Description
PRESSURE-RESPONSIVE SWITCH
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to a cord switch which is switched over when a cord member of the cord switch is pressed.
Description of the Related Art Considering the safety for the user of the vehicle, a window regulator which is driven by a motor to raise and Lower a glass of a vehicle door, for example, has been provided in which a cord switch is mounted on a window frame of the vehicle door, and when any obstacle (or foreign object) has been jammed between the cord switch and the glass of the vehicle door, the cord switch is pressed and switched over, so that rotation of the motor is stopped or reversed.
As shown in Fig. 14; a cord switch 60 has a hollow flexible cord member 62 such as a silicone, a rubber or the like in which the cord member 62 is provided with contact lines 64 at an upper wall portion 62A (which corresponds to one of two wall portions of the~cord member 62 generally opposed to each other) and at a lower wall portion 62B
(which corresponds to the other of the two wall portions), respectively. 4Yhen the cord member 62 is pressed, these contact lines 64 are made contact each other.
However, when the cord switch 60 is mounted on the window frame of the vehicle door, it may be bent largely at the corner of the window frame. Therefore, the contact lines 64 may be made contact each other when t:he cord switch 6() is mounted on the window frame.
Therefore, in a cord switch 72 shown in Fig. 15, a bridge conductor 68 is disposed at an upper wall portion 66A
oj' a cord member 66 and two contact lines 71 a:re disposed at a lower wall portion 66B of the cord member 66 with a barrier wall 70 being interposed between these contact lines 71. (see Japanese Utility Model Application No. 5-41282).
The cord switch 72 is structured such that even when a bending force is applied to the cord switch 72, because the distal end portion of the barrier wall 70 abuts on the bridge conductor 68, the bridge conductor 68 and the contact lines 71 are not made contact each other unnecessarily.
However, unless a pressing force which acts on the cord member 66 is strong enough to deform the barrier wall 70, the bridge conductor 68 do not contact these contact lines 71.. Further, when the pressing force acts on l~he barrier wall 70 vertically, the bridge conductor 68 is pressed in parallel to the barrier wall 70 and does contact the contact 21875.9 i_ines 71. However, if the pressing force acts on the barrier wall 70 from a transverse or diagonal direction, the barrier wall 70 is not deformed but is inclined due to the pressing force, the bridge conductor 68 is pressed diagonally, so that the bridge conductor 68 does not contact any of the contact lines 71.
In view of the aforementioned facts, it is an object of l:he present invention to provide a cord switch in which the desired bendability of t:he cord switch is accomplished, a contact portion and a contact body are not made contact each other even when the cord switch is bent or flexed, the contact portion and the contact body are made contact each other even when a pressing force which acts on the cord switch is relatively small, and the contacvt portion and the contact body are made contact each other, regardless of the angle at which the cord switch is pressed.
SUMMARY OF THE INVEN'I'IOi~~
In accordance with a first aspect of the present invention, a cord switch comprises a i'lexible hollow cord member which inc7.udes a predetermined wall portion and an opposing portion which generally opposes to the predetermined wall portLon and has a transverse cross sectional. configuration i.n which a neutral axis of the cord switch is pro vided at the predetermined wail portion side oL' 218~~~~9 t:he center of the distance between the pre: determined wa:l1 portion and the opposing- portion, a contacvt portion which is disposed inwardly of the hollow cord member and which extends on a portion of the predetermined wall. portion along t:he longitudinal direction of the hollow cord member, and a contact body which is disposed apart from the contact portion and extends along the longitudina_L direction of the hollow cord member, the contact body being di=;posed .inwardly of the hollow cord member and extending from t:he opposing portion to the portions between the predetermined wall L~ortion and the opposing' portion in the hol:Low cord member as viewed from a transverse cross section of t;he hollow cord member.
Namely, the cord switch according to the first aspect crf the present invention is characterized in that the cord switch has a cross sectional. configurati.orr of the flexible ho:Llow cord member, in which the neutral axis of the cord ~;wit:ch is provided at the predetermined wul:L portion side of t:he center or the di_stanc:e between the predetermined wall portion and the opposing portion which gerrera.l.ly opposes to the predetermined wall portion.
For example, when the cord switch according to the first aspect is mounted along an inner peripheral portion of a window frame o1' rz vehicle door through the predetermined wallportion oP the o.ord member, a portion of t:he cord 21870~~
switch which is posit=Toned at the corner portion of the window frame is bent such that a tensi.:l.e stress is applied i~o the predetermined wall portion of t:he c~.ord member and a compression stress is applied to the oppo sing portion thereof. However, the cord switch is more bendable at the opposing portion of the cord member because the distance between the opposing portion and the neutral axis is longer l~han that between the neutral axis and the predetermined wall portion, so that the mounting of the cord switch on the corner portion of the window frame or the like of the vehicle can be facilitated. Therefore, even at the corner portion of the window frame, the cross sectional configuration of the opposing portion of the cord member before the cord switch i.s bent can be maintained, and unless the opposing portion of the cord member is pressed inwardly of the cord switch, an unnecessary contact. bel~ween the contact portion and the contact body can be prevented.
Further, positioning the neutral axis at the predetermined wall portion side can be accomplished by inclining the side wall portions of the cord member posi-boned between the predetermined wall portion anal the opposing portion so as t;o approach each other toward the opposing portion. The cross sec~tion<zl conf'i_gurat:ion of the cord member may gave a generally trupc:zoicl~.r-1_, a gencarally semi-circu.Lar or a generally tri.angul<zr c<>nl'It;uration. For 218705.9 example, if the cross sectional conf iguration of the cord member is generally trapezoidal, the predeternnined wall portion is a wall portion which corresponds to a bottom side of the trapezoid. If the cross sectional configuration of the cord member is generally semi-circular, the predetermined wall portion is a wall. portion vvhich corresponds to a chord portion of the semi-circle and the opposing portion of the cord member is a wall portion which corresponds to a substantially center point (i.e., central portion) of an arc of the semi-circle. Further, if the cross sectional configuration of the cord member is generally triangular, the predetermined wall portion. is a wall portion which corresponds to one of the i~hree sides of l~he triangle and the opposing portion is a waT~l portion which corresponds to a vertex of the triangle..
The contact body is disposed so as to cover the contact portion by extending from both of the sidce wa~'~1 portions to l~he opposing portion in the cord member. Therefore, regardless of the ang:Le at which the cord swii:ch according 1~o the first aspect is pressed, the contact body and the contao.t portion necessarily contact each other, so that very reliab:Le switching-over of the cord switch can be effected f_n the cord switch.
In accordance with a second aspect of the present ~:nventLon, the cord switch according t-o the first aspect is 2187U~'~
provided in which at least one of the contact portion and the contact body is made of a conductive rubber or a conductive rubber in which a wire is embedded. For this reason, these contact portion and contact body can be deformed easily in conformity with deformation or bending of r~he cord switch. As a result, the cord switch itself according to the second aspect of the present invention can be deformed or bent easily.
In accordance with a third aspect of the present invention,the cord switch according to the first or second aspect provided in which one the cord switch and a is of rnember be mounted on which the cordswitch is mounted has to a projecting portion anti the otherof the cord switch and ohe memberto be mounted on which the cord swatch is mounted has a recessed portion into which the projecting portion is press-fitted. For this reason, the projec:tin~; portion is press-fitted into the recessed portion by merely pressing the cord switch. Further, the projecting porl~ion may be a convex line which extends along the Longitudinal direction of the one of the cord switch and the member 1~o be mounted on which the cord switch is mounted, while the recessed portion m<~y be a groove which extends along the longitudinal direction of the other of the cord switch and the member to be mounted on which t:he cord switch is mounted. Moreover, i~he projecting portion or the recessed portion is provided at the predetermined wall portion.
In accordance with a fourth aspect of the present Invention, the cord swit:ch ac.~cord=ing to the first or second aspect is mounted by means of adhesion, embedding or press-fitting on a member to be mounted on which the cord switch ~_s mounted along the inner periphery of a window frame for a window glass which can raise and lower. Ln this case, when any obstacle has been jammed between the glass and the cord switch, the contact body contacts the contact potion. and switching-over of the cord switch is conducted. As a result, it is sensed that the glass has strucl~; any obstacle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in Fi.g. l, a cord switch 10 according to a first embodiment of the present invention has a flexible hollow cord member 12. The cord member _L2 has a trapezoidal cross sectional configuration. In this w<iy, since the cord member 12 has a trapezoidal cross se<:tiontil configuration, a neutral axis N of the cord member 12 is positioned at an upper wall portion 12A side o-f the center of t:he distance t~etween the upper wall portion 12A and the lower wall yortion 12B, so that the cord member f2 is more bendable at t:he lower wallportion 128 thereof than is at the upper wall portion 12A thereof', and the mounting of i:he cord member 7.2 on a window frame 23 of a vehicle can be f~cil_itated.
I~urther, even when a tensile force is appl.i.ed to the upper wall_ portion 12A and a compression force is applied to the Lower wall portion 12B, namely, the cord member 12 is bent such that the lower wall portion 12B is pc>sit:ioned inwardly, a substantially original cross sectional conf:igurati.on of the cord member 12 is maintained at the lower wall portion L2B thereof, so that an oversensitive contact between the upper wall portion .12A and the lower wall portion 12B is prevented, that is, a malfunction of the cord switch is prevented. In addition, the upper wall portion l_2A
corresponds to one of the two wall. portions which substantially oppose to each other, of the cord member 12.
On the other hand, the lower wall portion 12B, that is, the opposing portion described in the above aspects, corresponds to the other of the two wall portions.
On the other hand, at ~z substantially central portion of the upper wall portion 12A, a c:onduc:tive rubber 1.4 constituting a contact portion is provided to extend along the longitudinal direction of the cord rnernber 12. lrr this way, when the conductive rubber 14 serving as a contact portion is used, the whole body of the cord switch 1.0 becomes more bendable than tire body of a cord sw tch in which only metal cvonductive lines are used. P~Ioreover, the conductive rubber 14 has a wire 16 which i.s embedded at the core portion thereoY and decreases the eloctr:ical_ resistano,e LL
z of the conductive rubber 14.
Meanwhile, a conductive rubber 20 in which a wire 18 is embedded is disposed in the cord member 12 so as to extend from side wall portions 12C of the cord member 12 which are substantially opposed to each other to the lower wall portion 12B
in a generally U-shaped configuration. The wire 18 is preferably positioned at one end portion of the contact body formed by the conductive rubber 20, and is embedded in the conductive rubber 20 so as to not be exposed.
Next, a description of a state in which the cord switch 1c) according to the present embodiment is mounted on a window frame of a vehicle door will be given in detail hereinafter.
As shown in Fig. 6, a weather strip 24 is mounted on the generally rectangular window frame 23 of the vehicle door to be bent along an inner peripheral wall thereof. As shown in Fig. 1, the weather strip 24 has a cross section of a generally L-shaped configuration. A glass sealing member 26 is attached to a step portion 24A of the weather strip 24. An outer edge of the raised door glass 28 is fitted into the glass sealing member 26 to close the opening of the window frame 23.
Further, the upper wall portion 12A of the cord member 12 is adhered to the lower edge portion 24B of the weather strip 24 and the cord switch 10 is disposed at a position slightly shifted from the moving track of the door glass 28.
For this reason, even when the door window is closed fully by the window glass 28, the cord switch 10 is n.ot pressed by A
2l 870~~9 the door g:Lass 28 and is not switched over-, according:Ly.
'Cherefore, it becomes unnecessary to dispose a limit: switch or the like for detecting the position of the door glass to determine whether the opening of the door wincjow has been fully closed by the door glass 28 or any obstacle has been jammed between the door glass and the window frame 23. As a result, a jam preventing mechanism is simplified and the control circuitry for the mechanism can also be simplified.
Further, even when the cord switch 10 is bent at a corner portion 24C of the weather strip 24, the cord switch ;_0 is more bendable at t:he lower wall portion 12B of the <:ord member 12 than at t;he upper wall portion 12A thereof, ~~o that the cord switch 10 can substantially nnaintain the cross sectional configuration thereof before i~he bending of i~he cord switch 10. Accordingly, the distance between the conductive rubber 14 and the conductive rubber 20 is maintained substantially constant before ~rnd after the bending of the cord swit:ch 10. As a result, an unnecessary contact between the conductive rubber 14 and the conductive rubber 20 can be prevented.
When any obstacle has been jammed, or c:iamped, bet4veen t:he door g.Lass 28 anti the cord switch 1.0, the lower wall_ portion 12B Ls pressed upwardly, and the conductive rubber 1.4 and the conduct ive rubbc>,r 20 are made contrict each other .
'There fore , thc~ cord swi teh 20 i. s swi tc~hed over , ror exarnp i_e , 1. ;3 21~705~
from ON to OF switching-over, or from OFF to ON switching-over so as to stop or reverse (i.e., inversely lower the window glass 28) an elevating apparatus (i.e.,. window regulator) which is not shown. Further, the sensitivity a d,justment of the cord switch 10 can be effected easily by changing the thicknesses of the cord member and the conductive rubber, and t:he distance between the conductive rubbers.
As shown in Fig. 2, regardless of the an~;le at which t:he cord switch 10 is pressed, very reliable switching-over can be effected in the cord switch 10.
As shown in Fig. 3, when a pressing force acts on the cord switch 10 upwardly, the lower wall portion 12B of the cord member 12 is deformed to protrude upwardly, so that the conductive rubber 14 and the conductive rubber 20 are made contact each other. As shown in F.ig. 4, when a pressing force from a directly transverse direction acts on the cord >witch 10, one of the side wall portions L2C of the cord member 12 is deformed to make the conductive rubber 14 and t:he conductive rubber 20 contact each other. Further, as shown in Fig. :p, a pressing force acts on the cord sw tch 10 diagonally, one of the sidewaLl port.i.ons i.2C and the Lower wall portion 12B are deformed to make t:he conductive rubber l.4 and the conductive rubber 20 contact each other.
It should be noted that the cross seotLOnal I.4 2187~~9 ~~onf'iguration of the cord member 12 is not limited t=o a trapezoidal. In order to position a neutral axis of the cJord member at the upper wal=L portion side of the center of the distance between the upper wa_L1 portion and the lower wall portion, a triangu:Lar cord switch 30 according to a :second embodiment of the present invention may be used as shown in Fig. 7 and a semi-circular cord switch 32 according ~to a third embodiment of the present invention may be used as shown in Fig. 8.
In accordance with the present embodiment, the cord switch J_0 is adhered to the weather strip 24. However, as shown in Fig. 9, the cord switch 10 may be embedded in the weather strip 24. Further, as shown in Fig. 10, by forming a T-shaped projection (i.e., convex) 40 on thc~ upper wall portion 12A of the cord member 12 and providing on t=he weather strip 24, a recessed portion (i.e., groove) 42 into which the T-shaped projection 40 is press-fitted, the mounting work of the cord switch 12 can be fac:ilitat:ed. I'he cross sectional configuration of a-~ project;ion is not: limited 1:o a T-shaped c~.onfigurat=ion. Namely, an anchor-shaped I; arrow-shaped) pro,jecti.t~n (i..e., convex) :>0 which is shown i:n Fig. 11 or an umbre lla-shaped pro,j ecvt ion ( :L . a . , convex) >2 which is shown in Fig. 1Z may be used, al_tE~rnatively.
L~urther, as shown in fig. 13, a projecting portion or a convex 56 may be Formed on tire weather strip 24 and a recessed portion (i..e., groove) 78 into which the project.in~r portion or the convex ~E> is press-fitted may be formed in vhe cord member 12.
Further, the present embodiment has been applied to a ,jam preventing apparatus used for the door glass of the vehicle. However, the present invention cyan be applied to a c~riverless or radio-controlled vehicle in which the cord switch is mounted on a bumper or the like of the vehicle in order to detect a collision of the vehicle. The present invention can also be applied to prevent any obstacle from being jammed in a so-called sunroof system in which a movable portion of a vehicle roof is automatically opened and closed and in an autodoor system of a 1-box-car type vehicle or the like. Thus, the present invenl~ion may be used for a jam preventing application or the like in which a cord switch is provided to be bent adjacent to a movable portion of a vehicle body to prevent any obstacle from being ,jammed around the movab7.e portion of i=he vehicle body.
Since the cord switch according to the present -nvention has the above-described structure, i~he cord swit=ch is more bendable than a conventional cord switch. Namely, l~he contact portion and the contao.t body s.Lre not made contact each other even when the cord swito.h is bent, they contact each ot=her even when a pressing force which acts on t=he cord swito.h is small., and they contact each other L Ei 2 ~ 87059 i°egardless of the angle at which the cord swiitch is pressed.
BACKGROUND OF THE INVENTION
Field of the Invention The present invention relates to a cord switch which is switched over when a cord member of the cord switch is pressed.
Description of the Related Art Considering the safety for the user of the vehicle, a window regulator which is driven by a motor to raise and Lower a glass of a vehicle door, for example, has been provided in which a cord switch is mounted on a window frame of the vehicle door, and when any obstacle (or foreign object) has been jammed between the cord switch and the glass of the vehicle door, the cord switch is pressed and switched over, so that rotation of the motor is stopped or reversed.
As shown in Fig. 14; a cord switch 60 has a hollow flexible cord member 62 such as a silicone, a rubber or the like in which the cord member 62 is provided with contact lines 64 at an upper wall portion 62A (which corresponds to one of two wall portions of the~cord member 62 generally opposed to each other) and at a lower wall portion 62B
(which corresponds to the other of the two wall portions), respectively. 4Yhen the cord member 62 is pressed, these contact lines 64 are made contact each other.
However, when the cord switch 60 is mounted on the window frame of the vehicle door, it may be bent largely at the corner of the window frame. Therefore, the contact lines 64 may be made contact each other when t:he cord switch 6() is mounted on the window frame.
Therefore, in a cord switch 72 shown in Fig. 15, a bridge conductor 68 is disposed at an upper wall portion 66A
oj' a cord member 66 and two contact lines 71 a:re disposed at a lower wall portion 66B of the cord member 66 with a barrier wall 70 being interposed between these contact lines 71. (see Japanese Utility Model Application No. 5-41282).
The cord switch 72 is structured such that even when a bending force is applied to the cord switch 72, because the distal end portion of the barrier wall 70 abuts on the bridge conductor 68, the bridge conductor 68 and the contact lines 71 are not made contact each other unnecessarily.
However, unless a pressing force which acts on the cord member 66 is strong enough to deform the barrier wall 70, the bridge conductor 68 do not contact these contact lines 71.. Further, when the pressing force acts on l~he barrier wall 70 vertically, the bridge conductor 68 is pressed in parallel to the barrier wall 70 and does contact the contact 21875.9 i_ines 71. However, if the pressing force acts on the barrier wall 70 from a transverse or diagonal direction, the barrier wall 70 is not deformed but is inclined due to the pressing force, the bridge conductor 68 is pressed diagonally, so that the bridge conductor 68 does not contact any of the contact lines 71.
In view of the aforementioned facts, it is an object of l:he present invention to provide a cord switch in which the desired bendability of t:he cord switch is accomplished, a contact portion and a contact body are not made contact each other even when the cord switch is bent or flexed, the contact portion and the contact body are made contact each other even when a pressing force which acts on the cord switch is relatively small, and the contacvt portion and the contact body are made contact each other, regardless of the angle at which the cord switch is pressed.

switch which is posit=Toned at the corner portion of the window frame is bent such that a tensi.:l.e stress is applied i~o the predetermined wall portion of t:he c~.ord member and a compression stress is applied to the oppo sing portion thereof. However, the cord switch is more bendable at the opposing portion of the cord member because the distance between the opposing portion and the neutral axis is longer l~han that between the neutral axis and the predetermined wall portion, so that the mounting of the cord switch on the corner portion of the window frame or the like of the vehicle can be facilitated. Therefore, even at the corner portion of the window frame, the cross sectional configuration of the opposing portion of the cord member before the cord switch i.s bent can be maintained, and unless the opposing portion of the cord member is pressed inwardly of the cord switch, an unnecessary contact. bel~ween the contact portion and the contact body can be prevented.
Further, positioning the neutral axis at the predetermined wall portion side can be accomplished by inclining the side wall portions of the cord member posi-boned between the predetermined wall portion anal the opposing portion so as t;o approach each other toward the opposing portion. The cross sec~tion<zl conf'i_gurat:ion of the cord member may gave a generally trupc:zoicl~.r-1_, a gencarally semi-circu.Lar or a generally tri.angul<zr c<>nl'It;uration. For 218705.9 example, if the cross sectional conf iguration of the cord member is generally trapezoidal, the predeternnined wall portion is a wall portion which corresponds to a bottom side of the trapezoid. If the cross sectional configuration of the cord member is generally semi-circular, the predetermined wall portion is a wall. portion vvhich corresponds to a chord portion of the semi-circle and the opposing portion of the cord member is a wall portion which corresponds to a substantially center point (i.e., central portion) of an arc of the semi-circle. Further, if the cross sectional configuration of the cord member is generally triangular, the predetermined wall portion. is a wall portion which corresponds to one of the i~hree sides of l~he triangle and the opposing portion is a waT~l portion which corresponds to a vertex of the triangle..
The contact body is disposed so as to cover the contact portion by extending from both of the sidce wa~'~1 portions to l~he opposing portion in the cord member. Therefore, regardless of the ang:Le at which the cord swii:ch according 1~o the first aspect is pressed, the contact body and the contao.t portion necessarily contact each other, so that very reliab:Le switching-over of the cord switch can be effected f_n the cord switch.
In accordance with a second aspect of the present ~:nventLon, the cord switch according t-o the first aspect is 2187U~'~
provided in which at least one of the contact portion and the contact body is made of a conductive rubber or a conductive rubber in which a wire is embedded. For this reason, these contact portion and contact body can be deformed easily in conformity with deformation or bending of r~he cord switch. As a result, the cord switch itself according to the second aspect of the present invention can be deformed or bent easily.
In accordance with a third aspect of the present invention,the cord switch according to the first or second aspect provided in which one the cord switch and a is of rnember be mounted on which the cordswitch is mounted has to a projecting portion anti the otherof the cord switch and ohe memberto be mounted on which the cord swatch is mounted has a recessed portion into which the projecting portion is press-fitted. For this reason, the projec:tin~; portion is press-fitted into the recessed portion by merely pressing the cord switch. Further, the projecting porl~ion may be a convex line which extends along the Longitudinal direction of the one of the cord switch and the member 1~o be mounted on which the cord switch is mounted, while the recessed portion m<~y be a groove which extends along the longitudinal direction of the other of the cord switch and the member to be mounted on which t:he cord switch is mounted. Moreover, i~he projecting portion or the recessed portion is provided at the predetermined wall portion.
In accordance with a fourth aspect of the present Invention, the cord swit:ch ac.~cord=ing to the first or second aspect is mounted by means of adhesion, embedding or press-fitting on a member to be mounted on which the cord switch ~_s mounted along the inner periphery of a window frame for a window glass which can raise and lower. Ln this case, when any obstacle has been jammed between the glass and the cord switch, the contact body contacts the contact potion. and switching-over of the cord switch is conducted. As a result, it is sensed that the glass has strucl~; any obstacle.

DESCRIPTION OF THE PREFERRED EMBODIMENT
As shown in Fi.g. l, a cord switch 10 according to a first embodiment of the present invention has a flexible hollow cord member 12. The cord member _L2 has a trapezoidal cross sectional configuration. In this w<iy, since the cord member 12 has a trapezoidal cross se<:tiontil configuration, a neutral axis N of the cord member 12 is positioned at an upper wall portion 12A side o-f the center of t:he distance t~etween the upper wall portion 12A and the lower wall yortion 12B, so that the cord member f2 is more bendable at t:he lower wallportion 128 thereof than is at the upper wall portion 12A thereof', and the mounting of i:he cord member 7.2 on a window frame 23 of a vehicle can be f~cil_itated.
I~urther, even when a tensile force is appl.i.ed to the upper wall_ portion 12A and a compression force is applied to the Lower wall portion 12B, namely, the cord member 12 is bent such that the lower wall portion 12B is pc>sit:ioned inwardly, a substantially original cross sectional conf:igurati.on of the cord member 12 is maintained at the lower wall portion L2B thereof, so that an oversensitive contact between the upper wall portion .12A and the lower wall portion 12B is prevented, that is, a malfunction of the cord switch is prevented. In addition, the upper wall portion l_2A
corresponds to one of the two wall. portions which substantially oppose to each other, of the cord member 12.
On the other hand, the lower wall portion 12B, that is, the opposing portion described in the above aspects, corresponds to the other of the two wall portions.
On the other hand, at ~z substantially central portion of the upper wall portion 12A, a c:onduc:tive rubber 1.4 constituting a contact portion is provided to extend along the longitudinal direction of the cord rnernber 12. lrr this way, when the conductive rubber 14 serving as a contact portion is used, the whole body of the cord switch 1.0 becomes more bendable than tire body of a cord sw tch in which only metal cvonductive lines are used. P~Ioreover, the conductive rubber 14 has a wire 16 which i.s embedded at the core portion thereoY and decreases the eloctr:ical_ resistano,e LL
z of the conductive rubber 14.
Meanwhile, a conductive rubber 20 in which a wire 18 is embedded is disposed in the cord member 12 so as to extend from side wall portions 12C of the cord member 12 which are substantially opposed to each other to the lower wall portion 12B
in a generally U-shaped configuration. The wire 18 is preferably positioned at one end portion of the contact body formed by the conductive rubber 20, and is embedded in the conductive rubber 20 so as to not be exposed.
Next, a description of a state in which the cord switch 1c) according to the present embodiment is mounted on a window frame of a vehicle door will be given in detail hereinafter.
As shown in Fig. 6, a weather strip 24 is mounted on the generally rectangular window frame 23 of the vehicle door to be bent along an inner peripheral wall thereof. As shown in Fig. 1, the weather strip 24 has a cross section of a generally L-shaped configuration. A glass sealing member 26 is attached to a step portion 24A of the weather strip 24. An outer edge of the raised door glass 28 is fitted into the glass sealing member 26 to close the opening of the window frame 23.
Further, the upper wall portion 12A of the cord member 12 is adhered to the lower edge portion 24B of the weather strip 24 and the cord switch 10 is disposed at a position slightly shifted from the moving track of the door glass 28.
For this reason, even when the door window is closed fully by the window glass 28, the cord switch 10 is n.ot pressed by A
2l 870~~9 the door g:Lass 28 and is not switched over-, according:Ly.
'Cherefore, it becomes unnecessary to dispose a limit: switch or the like for detecting the position of the door glass to determine whether the opening of the door wincjow has been fully closed by the door glass 28 or any obstacle has been jammed between the door glass and the window frame 23. As a result, a jam preventing mechanism is simplified and the control circuitry for the mechanism can also be simplified.
Further, even when the cord switch 10 is bent at a corner portion 24C of the weather strip 24, the cord switch ;_0 is more bendable at t:he lower wall portion 12B of the <:ord member 12 than at t;he upper wall portion 12A thereof, ~~o that the cord switch 10 can substantially nnaintain the cross sectional configuration thereof before i~he bending of i~he cord switch 10. Accordingly, the distance between the conductive rubber 14 and the conductive rubber 20 is maintained substantially constant before ~rnd after the bending of the cord swit:ch 10. As a result, an unnecessary contact between the conductive rubber 14 and the conductive rubber 20 can be prevented.
When any obstacle has been jammed, or c:iamped, bet4veen t:he door g.Lass 28 anti the cord switch 1.0, the lower wall_ portion 12B Ls pressed upwardly, and the conductive rubber 1.4 and the conduct ive rubbc>,r 20 are made contrict each other .
'There fore , thc~ cord swi teh 20 i. s swi tc~hed over , ror exarnp i_e , 1. ;3 21~705~
from ON to OF switching-over, or from OFF to ON switching-over so as to stop or reverse (i.e., inversely lower the window glass 28) an elevating apparatus (i.e.,. window regulator) which is not shown. Further, the sensitivity a d,justment of the cord switch 10 can be effected easily by changing the thicknesses of the cord member and the conductive rubber, and t:he distance between the conductive rubbers.
As shown in Fig. 2, regardless of the an~;le at which t:he cord switch 10 is pressed, very reliable switching-over can be effected in the cord switch 10.
As shown in Fig. 3, when a pressing force acts on the cord switch 10 upwardly, the lower wall portion 12B of the cord member 12 is deformed to protrude upwardly, so that the conductive rubber 14 and the conductive rubber 20 are made contact each other. As shown in F.ig. 4, when a pressing force from a directly transverse direction acts on the cord >witch 10, one of the side wall portions L2C of the cord member 12 is deformed to make the conductive rubber 14 and t:he conductive rubber 20 contact each other. Further, as shown in Fig. :p, a pressing force acts on the cord sw tch 10 diagonally, one of the sidewaLl port.i.ons i.2C and the Lower wall portion 12B are deformed to make t:he conductive rubber l.4 and the conductive rubber 20 contact each other.
It should be noted that the cross seotLOnal I.4 2187~~9 ~~onf'iguration of the cord member 12 is not limited t=o a trapezoidal. In order to position a neutral axis of the cJord member at the upper wal=L portion side of the center of the distance between the upper wa_L1 portion and the lower wall portion, a triangu:Lar cord switch 30 according to a :second embodiment of the present invention may be used as shown in Fig. 7 and a semi-circular cord switch 32 according ~to a third embodiment of the present invention may be used as shown in Fig. 8.
In accordance with the present embodiment, the cord switch J_0 is adhered to the weather strip 24. However, as shown in Fig. 9, the cord switch 10 may be embedded in the weather strip 24. Further, as shown in Fig. 10, by forming a T-shaped projection (i.e., convex) 40 on thc~ upper wall portion 12A of the cord member 12 and providing on t=he weather strip 24, a recessed portion (i.e., groove) 42 into which the T-shaped projection 40 is press-fitted, the mounting work of the cord switch 12 can be fac:ilitat:ed. I'he cross sectional configuration of a-~ project;ion is not: limited 1:o a T-shaped c~.onfigurat=ion. Namely, an anchor-shaped I; arrow-shaped) pro,jecti.t~n (i..e., convex) :>0 which is shown i:n Fig. 11 or an umbre lla-shaped pro,j ecvt ion ( :L . a . , convex) >2 which is shown in Fig. 1Z may be used, al_tE~rnatively.
L~urther, as shown in fig. 13, a projecting portion or a convex 56 may be Formed on tire weather strip 24 and a recessed portion (i..e., groove) 78 into which the project.in~r portion or the convex ~E> is press-fitted may be formed in vhe cord member 12.
Further, the present embodiment has been applied to a ,jam preventing apparatus used for the door glass of the vehicle. However, the present invention cyan be applied to a c~riverless or radio-controlled vehicle in which the cord switch is mounted on a bumper or the like of the vehicle in order to detect a collision of the vehicle. The present invention can also be applied to prevent any obstacle from being jammed in a so-called sunroof system in which a movable portion of a vehicle roof is automatically opened and closed and in an autodoor system of a 1-box-car type vehicle or the like. Thus, the present invenl~ion may be used for a jam preventing application or the like in which a cord switch is provided to be bent adjacent to a movable portion of a vehicle body to prevent any obstacle from being ,jammed around the movab7.e portion of i=he vehicle body.
Since the cord switch according to the present -nvention has the above-described structure, i~he cord swit=ch is more bendable than a conventional cord switch. Namely, l~he contact portion and the contao.t body s.Lre not made contact each other even when the cord swito.h is bent, they contact each ot=her even when a pressing force which acts on t=he cord swito.h is small., and they contact each other L Ei 2 ~ 87059 i°egardless of the angle at which the cord swiitch is pressed.
