Abstract

A securing means for receiving objects on grid surfaces formed from horizontally and vertically running grid bars comprises a fastening element (1a-1f) which has an upper and open groove (4), which passes through the fastening element (1a-1f), and a lower and open groove (5) which likewise passes through the fastening element (1a-1f), the grooves (4, 5) - relative to the use position of the fastening element (1a-1f) - running in the direction of adjacent and parallel, horizontal grid bars (2, 3) and being at a corresponding spacing from one another. The upper groove (4) extends from the upper end side (10) of the fastening element (1a-1f) into said element, and the lower groove (5) runs perpendicularly thereto and is open towards the rear side of the fastening element (1a-1f). Owing to this configuration, the fastening element (1a-1f) can be easily placed on the two abovementioned grid bars (2, 3), the upper grid bar (2) extending through the upper groove (4) and the lower grid bar (3) extending through the lower groove (5). A load-bearing element (6) for receiving objects can be fastened in a bore (23) between the grooves (4, 5). An object suspended in this way exerts, owing to its weight, a moment on the fastening element (1a-1f), under the effect of which moment the fastening element (1a-1f) is pressed firmly onto the grid bars (2, 3). <IMAGE>

Description

The invention relates to a holder for holding objects on grid surfaces,
consisting of a fastening element which can be attached to horizontal or oblique bars parallel to one another and at a predetermined distance from one another,
to which at least one support element can be attached.

Where tools, hand machines and other devices are received by known holders of the aforementioned type on usually vertical grid surfaces, which can be bordered, for example, by profile frames, a steel fastening element with a hook-like upper end can be used, which is hooked onto the horizontal grid bars. Otherwise, the fastening element is in the form of a tab, from the central section of which a hook which can be fastened to the tab for receiving the devices etc. protrudes and the lower end of which rests on the grating bar next to the bottom, so that the fastening element does not rotate backwards under load. The main disadvantage of such a fastening element is that it can easily detach from the lattice bar and fall off if it is accidentally touched, possibly even with the attached device. For the same reason, items must be attached to the fastener hooks with great care.

Another known fastener has the shape of a rectangular plate made of hard plastic, is provided at the front with at least one vertically projecting metal hook and has two upper and two lower hooks on the back for attaching the fastener to two parallel spaced one above the other strip-shaped bars of a grid surface or a suspension plate. The fastening element can optionally also be attached to sheet metal plates perforated in a certain pattern, the four hooks engaging in appropriately arranged four holes. A parallel shift is possible when attaching to the bars. So that the fastening element is firmly attached to the bars or on the perforated plate and does not fall off when lightly touched, a tongue that projects obliquely backwards is provided in the lower part of the fastening element, which under pressure when attaching the fastening element to the perforated plate or to the lattice bars is spring loaded. Practice shows, however, that despite the resilient tongue, the fastening element can easily detach from the perforated plate or from the lattice bars when handled carelessly in the region of the fastening element. In addition, the fastener has a jagged and correspondingly difficult to manufacture shape.

Holders are known in which the lower end of the fastening element can be screwed to the receiving surface while the upper hook-shaped end of the fastening element is hooked in, but these are perforated plate receiving surfaces with a rigidly predetermined hole pattern, so that the spacing of the fastening elements in the horizontal is fixed and cannot be changed flexibly. In addition, the fastening elements are made of steel with a relatively high outlay and have - depending on the object to be accommodated - different shapes. The attachment of the fasteners to the perforated plates requires a relatively long time by screwing after the fastening of the fastener in at least two holes. The same applies to a possible moving of fasteners.

Finally, fasteners of the aforementioned type must also be tilt-proof so that the suspended objects cannot swing about a vertical axis. A tipping or pendulum-proof fastening of the fastening element to the grille does not result in the fastening elements mentioned at the beginning with a hook-shaped upper end, and in the case of the fastening elements which can be screwed tight, it can essentially only be achieved with the fastening elements which engage in four holes.

Finally, it is also known to use such brackets in shops, where, for example, large double hooks (meat hooks) are used to hang clothes hangers on grating surfaces. It is obvious that such hooks as fastening elements cannot be used to securely hold objects on grid surfaces.

To avoid the above disadvantages, the invention provides that
- Based on the position of use of the fastening element - in the upper section of the fastening element, an upper groove crossing the fastening element in the direction of an upper lattice bar to be received in this groove
and in the lower section of the fastening element, a lower groove passing through the fastening element runs in the direction of a lower lattice bar to be received in this groove,
with both grooves facing from the direction of the bars extend essentially parallel outer surfaces of the fastening element into the fastening element,
the width of the grooves essentially corresponds to the diameter of the bars or in any case is not unnecessarily far above it,
the two grooves are arranged in such a position with respect to one another and on the fastening element that the fastening element can be placed directly at one fastening point on the two lattice bars lying one above the other, the upper lattice bar being received in the upper groove and the lower lattice bar in the lower groove
and wherein the fastening element for receiving vertically acting forces caused by the weight of the object held by the fastening element by applying one or more corresponding, in cross-section, substantially horizontally straight or curved groove surfaces of the upper and / or lower groove on the upper and / or lower lattice bar lies on
and wherein horizontal forces originating from the held object press the fastening element against the upper and lower lattice bars via groove surfaces which are essentially straight or curved in cross section,
and at least one receptacle, in particular as an opening or bore in the fastening element, is provided for fastening the support element, for example a hook, to the fastening element between the upper and the lower groove.

This design of the holder according to the innovation or its fastening element allows the fastening element to be simply attached to or placed on two grille bars lying parallel and one above the other at any point on the grille surface, in particular without restriction or specification of the fastening point in the horizontal direction. Regardless of which of the preferred modern mounts to be explained below is selected, in any case a secure attachment to the upper and lower ends of the fastening element is achieved immediately when the fastening element is placed on the upper and lower bars.

Essentially horizontally, either straight or in an approximately horizontal position, curved groove surfaces of at least one of the two grooves absorb any type of vertical forces. Corresponding groove surfaces of at least one of the two grooves, which are either straight or curved in the vertical direction, absorb the horizontal forces which can act on the fastening element. Thus, easy attachment of the fastener with the property of a secure attachment, especially under load, is achieved by the new design. The lateral displaceability of the fastening elements is retained, which is not only advantageous when later placing and pushing together suspended objects, but in particular also facilitates assembly if the fastening elements are used in pairs to form a relatively wide holder. It is also very important that a tilt and pendulum-proof mounting of the fastener on the upper and lower bars What is achieved is that correspondingly wide groove surfaces are available at the top and bottom for a correspondingly wide support on both lattice bars. A comparable stability has so far only been achieved with brackets in which the fastening elements on rods or the like have to be pulled up like pearls on a cord, so that the through openings or grooves have no lateral opening to the outside, as in the case of the new design, which is necessary is to put on or attach the fastener just at any point on the grid surface directly from the front.

A first preferred embodiment of the aforementioned holder according to the innovation is characterized in that
the upper groove - based on the position of use of the fastening element - essentially vertically from the top of the fastening element
and the lower groove extends substantially horizontally into the fastening element from the rear side of the fastening element facing the grating surface and
the two grooves in the fastener are arranged in such a position that the fastener can be placed on the two parallel bars one above the other by spacing the fastener first from the front with the upper end over the upper tie rod, the upper groove the upper Grid bar receives, and the fastener is then pivoted so far in the direction of the lower grating bar that the lower grating bar is received in the lower groove while the upper grating bar still located in the top groove.

In this first embodiment, the upper end of the fastening element is practically fork-shaped through the upper groove, at least seen in cross section. Therefore, it is also very easy to place this fork-shaped upper end from the front of the grating surface onto the upper grating rod and then to pivot the lower end of the fastening element onto the lower grating rod and to place it on this rod in such a way that the lower groove is the lower grating rod embraces. Vertical forces are consequently transmitted to the lower lattice bar via the lower groove, while the upper part takes over the guiding and securing against horizontal forces. The height of the upper lattice bar within the upper groove is practically irrelevant. Under load from a received object, the rear leg of the upper end of the fastener is pressed against the upper tie rod and the inner end of the lower groove against the lower tie rod, so that an attached load reinforces the attachment of the fastener to the grid surface.

A variant of the aforementioned first embodiment results in a second version according to the innovation, in which the upper groove - based on the position of use of the fastening element - is essentially horizontal from the front of the fastening element and the lower groove also from the rear side of the fastening element facing the grid surface extends substantially horizontally into the fastening element and the distance between the two grooves essentially the distance between the two bars corresponds.

In this second embodiment, too, both bars are received in the two grooves in the position of use of the fastening element, the fastening element being attached to the two bars in an inclined position with the upper end behind the upper bar and with the lower end in front of the lower bar, to place the upper end on the upper lattice bar and the lower end on the lower lattice bar by rotating the fastening element appropriately about a central horizontal axis, in such a way that both lattice bars are located in the associated horizontal grooves. However, these can also have a slightly oblique profile, as seen in cross section, so that the lateral openings of the grooves each lie somewhat higher than their inner ends. In this case, too, there are all the advantages of the innovation, in particular the pressure of the upper end of the fastening element against the upper lattice bar and the lower end against the lower lattice bar increases under load, because the support element attached to the fastening element between the two grooves by the object or its force exerts a corresponding moment on the fastening element, which leads to the aforementioned pressing forces.

After a modification of this second embodiment, both grooves have inner extensions which are angled vertically upward.

Finally, a third embodiment according to the invention as well as a preferred embodiment is provided, in which the upper groove - based on the position of use of the fastening element - is bent upward in the body plane or angled extension is provided in an arcuate or angular cross-section, and the lower groove extends vertically from the underside of the fastening element into the fastening element and the fastening element can be placed on the two parallel grille bars lying one above the other by the extension of the angled upper groove the upper lattice bar and the lower groove the lower lattice bar.

In this embodiment, the upper end of the fastening element can be placed on the upper lattice bar in a manner comparable to a hook, the lower end being simultaneously placed on the lower lattice bar, and the fork-shaped lower end encompassing the lattice bar in a manner similar to the upper groove in the upper end of the fastener according to the first preferred embodiment according to the innovation. In the third embodiment here, the fastening element is carried by the angled upper groove on the upper lattice bar, while the lower groove, in any case preferably takes over the guiding and securing against horizontal forces. It can also be arranged so that it carries vertical forces.

After a modification of this third embodiment, the lower groove is angled in the same way as the upper groove.

There are particular advantages for the holder according to the innovation if the fastening element is designed as a solid body made of a hard plastic such as polyethylene or polyvinyl chloride of appropriate quality. The body should expediently be cuboid or plate-shaped. In addition, it should be as perpendicular to each other as possible Have front and back surfaces and parallel axes of the upper and lower grooves.

This design as a plastic block allows a particularly simple manufacture of the fastening element, because a plastic profile with a corresponding cross section, e.g. produced in the extruder and the individual fasteners need to be separated from this strand only in a suitable manner. The hole required for receiving the support element on the fastening element or a corresponding passage opening is produced either in connection with the extruder process or subsequently. The production of the fastener as a profile section allows the production of different width fasteners without any additional effort.

The key areas relevant to the stability of the seat of the fastener on the bars can be produced very easily and without any reworking, and these groove areas extend over the entire width of the fastener, so that a particularly wobble-resistant connection between the fastener and the bars can be produced.

Finally, the design of the fastener as a plastic body also leaves enough scope for any desired design of the design of the fastener, as well as in terms of color and other features such as transparency by using a transparent plastic. Appropriate external design of the fastening element expands its application options, especially where an appealing design is important such as shop fittings.

The further feature according to the invention is very important, in particular in connection with the production of the fastening element as a plastic body, according to which the fastening element can be resiliently clamped onto the corresponding lattice bar by the cross-sectional design of the lower and / or upper groove. Because this feature supports the simple placement of the fastener on the bars as well as its secure fit.

For the clamp fastening, it is expedient that the cross section of the lower and / or the upper groove comprises a narrowing and a subsequent widening from the outside inwards. In this case, the fastening element practically engages on the bars, so that a loosening of the fastening element from the bars is only possible with the appropriate effort. Nevertheless, a slight sideways movement can be maintained.

It is advantageous if the constriction can be resiliently widened when the fastening element is clamped onto the lattice bar, for example by means of an external groove in the body approximately at the level of the widening, so that the fastening element can be easily placed on the lattice bars in spite of the latching fastening resulting in the end position.

The cross section of the extension is preferably dimensioned such that there is a clamping fit of the fastening element on the lattice bar or on the lattice bars, which fixes the fastening element on the lattice bars, but also a displacement of the fastening element allowed along the bars under hand pressure.

The attachment of the support element or elements to the section of the fastening element lying between the two grooves is in itself arbitrary, but preferably a shaft of a support element is e.g. in the receptacle designed as a continuous bore. a hook can be picked up and secured in this position, for example by means of a nut / bolt fastening. The shaft of the support element can be particularly easily and securely attached to the fastening element if the through hole to create a secure press / clamp fit forms a conically narrowed receptacle for a substantially cylindrical shaft. The tapered receptacle is expediently smaller in diameter than the cylindrical shaft and is designed to be resilient so that the shaft, supported by the plastic leather properties, is held firmly by the conical receptacle.

In the preferred embodiment according to FIG. 1, a fastening element, generally designated 1a, of a holder according to the invention consists of a block-shaped body made of a hard plastic such as polyvinyl chloride or polyethylene of appropriate quality, the mutually perpendicular outer surfaces, namely an upper side 10, a lower side 11, a Front 12, a back 13 and two narrow sides 14, 15. A lower groove 5 extends across the fastening element 1 a in its lower section 7 and an upper groove 4 in the upper section 9. In this first embodiment, the upper groove 4 extends vertically downwards in the middle from the upper side 10, while the lower one Groove 5 runs from the rear 13 horizontally approximately to the center of the fastening element 1a. Since the upper and lower grooves 4 and 5 are continuous grooves, they are correspondingly open on the narrow sides 14, 15, as the drawing shows.

A bore 23 extends in the central section 8 of the fastening element 1 a from the rear side 13 to the front side 12, in a substantially vertical position to the aforementioned sides. It serves to accommodate any hook-shaped support element 6, for example, of which only the shaft is shown.

The arrangement and the course of the lower and upper groove 4, 5 on the fastening element 1 a is selected such that the fastening element 1 a, as the drawing shows, on an upper grating bar 2 and a lower grating bar 3 running parallel thereto at a distance and having a larger grating area , which is not shown, can be put on. For this purpose, the fork-shaped upper gate 9 of the fastening element 1 a, which is fork-shaped through the upper groove 4, is placed from the front in a horizontal or oblique position on the upper grating bar 2, so that the upper groove 4 encompasses the upper grating bar 2. The fastening element 1 a is then pivoted downward until the lower groove 5 has received the lower lattice bar 3, as shown.

When an object is attached to the support element 6, the fastening element 1a fastened to the upper and to the lower lattice bars 2 and 3 is subjected to a corresponding load. Vertical forces become effective, which in this embodiment of the fastening element 1 a are transmitted to the lower lattice bar 3 via the horizontally straight groove surface 17 that is curved at the end. At the same time, the horizontal forces K1 and K2 indicated schematically in FIG. 1 take effect as a result of a moment M exerted on the fastening element 1a by the attached object via the support element 6. These horizontal forces K1, K2 are absorbed by vertically straight or vertically curved groove surfaces 18 of the upper and lower grooves 4 and 5, respectively. The fastening element consequently receives a very secure fit, particularly under load, on or on the two lattice bars 2, 3. As a result of the width of the fastening element 1a, there are also sufficiently long or wide inner groove surfaces 17 and 18, so that no lateral ones Wobble or pendulum movements of the fastener 1a with respect to the bars 2, 3 can occur.

As can also be seen from the drawing, the lower groove 5 absorbs the vertically acting forces V, while the upper groove 4 only absorbs horizontal forces occurring from the front or from the rear.

In the preferred modification of the first embodiment shown in FIGS. 1 a and 1 b, with reference to FIG. 1, the same reference numerals designate corresponding parts of the fastening element shown there and generally designated 1 a ', so that the detailed description as described above is repeated 1 is omitted.

An essential difference of the fastening element 1 a 'compared to the fastening element 1 a is that a skeleton structure is provided on the inside, as before, with smooth-surface narrow sides 14, 15, a smooth-surface front 12 and the top and bottom sides 10 and 11, respectively, which can be seen in FIG 1b results. Except for the lower section 7, the fastening element 1a 'produced by the plastic injection molding process consists of a box open at the rear with a wall 30 running all around. Flush with the wall 30, two eyes 31 are arranged one above the other - related to the position of use of the fastening element 1a' , 32 with transverse ribs 33, 34 and 35, 36 to the adjacent wall 30 and with corresponding longitudinal ribs 37 and 38 and 39 for connecting and stiffening the structure. The longitudinal rib 37 runs obliquely towards a recessed inner wall 40 of the upper groove 4.

Below a web 5a forming the lower groove 5, a grip part 7a extends in the extension of the front side of the fastening element 1a 'on the lower section 7 to facilitate handling of the fastening element 1a', especially when putting on and taking off, in particular the lower section 7 of the fastening element 1a 'on or from the lower lattice bar 3.

Through the upper eye 31, the bore 23 extends z. B. for receiving the, as indicated in Fig. 1, support element 6, and the lower eye 32 has a continuous threaded bore 23a for optional insertion of a bolt provided with a corresponding external thread or the like, which can also serve as a support element. The stresses and force ratios resulting from the use of the fastener 1a 'when loaded by an attached object are the same as in the fastener 1a of Fig. 1 except for the difference that the through bore 23 and the through threaded bore 23a are vertical with respect to the central bore 23 of the fastener 1a of Fig. 1 are slightly offset.

It is very important that when attaching the fastening element 1 a 'there is a snap fastening between the upper grating bar 2 and the groove end 18 of the upper groove 4 and between the lower grating bar 3 and the corresponding groove end 18 of the lower groove 5. The fact that the bars 2, 3 snap or snap into the grooves 4 and 5 is due to the fact that the groove width, from the groove opening to the end of the groove, is smaller than the diameter of the bars and only at the groove end 18 by a slight increase in width or the radius at this point the clamping becomes smaller, in such a way that there is a secure snug fit or clamping fit at the groove end 18. This seat is dimensioned such that a lateral displacement of the fastening element 1 a 'along the bars 2, 3 is possible with clear finger pressure, but otherwise a tight fit of the fastening element 1 a' is achieved on the bars 2, 3, so that no unintentional Displacement can result. When the fastening element 1a 'is placed on the bars 2, 3, the webs 4a, 5a yield until the bars 2, 3 snap into the slightly enlarged groove ends 18. Here, the handle part 7a facilitates the handling of the fastener 1a '. 7, the clamp seat will be explained again later with reference to the geometry shown there.

In the second preferred embodiment shown in FIG. 2, the same reference numerals with reference to FIG. 1 correspond to the same parts of a fastening element shown there and generally designated 1b, so that a detailed description is omitted again. In contrast to the first embodiment, both grooves 4, 5 here run horizontally, based on the position of use of the fastening element 1b, namely the upper groove 4 from the front 12 and the lower groove 5 from the rear 13 approximately up to the middle of the fastening element 1b . When placing on the upper and lower bars 2 and 3, the fastener 1b is, for example, first guided with its upper portion 9 between the upper and lower bars 2 and 3 and preferably attached to the upper bar 2 from below so that the upper groove 4 receives the upper lattice bar 2. Then the lower section 7 of the Fastening element 1b on the lower lattice rod 3, so that it is finally received by the inner end of the lower groove 5, as shown. The essentially horizontally straight groove surfaces 17 of the upper and lower grooves 4 and 5 both take on the vertical forces V in this embodiment, while - especially under load - the vertically curved groove surface 18 of the upper groove 4 the horizontal force K1 and the corresponding groove surface 18 of the lower groove 5 absorbs the horizontal force K2.

As indicated by dotted lines, one or both of the grooves 4, 5 can be provided with an upwardly extending vertical extension 16 in order to make the fastening of the fastening element 1b on the upper and lower bars 2 and 3 even more secure and / or to facilitate the attachment of the fastening element 1b in this embodiment, because the extension 16 can be used for relative movements when one of the bars 2 is already in the associated groove while the second bar is being inserted into the groove assigned to it.

The third embodiment shown in FIG. 3 of a fastening element, generally designated 1c, does not require a detailed description, since the same reference numerals as in FIGS. 1 and 2 denote the same parts. The upper groove 4 here runs angularly as a result of a vertical inner extension 16, so that the upper section 9 of the fastening element 1c is hook-shaped and the fastening element 1c also experiences a connection corresponding to a hook with the upper lattice bar 2. Since the upper groove 4 extends from the rear 13 of the fastener 1c, the upper section can be 9 of the fastener 1c when mounting the fastener 1c on the bars 2, 3 very easily. First of all, the fastening element 1c, with its lower section 7, on which the lower groove 5 extends vertically upwards from the underside 11 of the fastening element 1c, can be easily placed on the lower grating bar 3, in order to subsequently attach the upper section 9 of the fastening element 1c to lead against the upper lattice bar 2 until it assumes the predetermined and illustrated position in the angular upper groove 4. 3 also shows the groove surfaces 17, which are curved in the horizontal, for absorbing vertical forces v and vertically straight groove surfaces 18 for absorbing horizontal forces K1 and K2.

The fastening element shown in FIG. 4 and generally designated 1d is essentially a modified embodiment of the second embodiment according to FIG. 2 of the fastening element 1b. The upper groove here does not extend horizontally from the front 12 as in the case of the fastening element 1b, but obliquely into the interior of the fastening element 1d, so that here too there is a hook-like suspension of the fastening element 1d on the upper lattice bar 2.

The embodiment shown further in FIG. 5 of a fastener fastened generally with 1e is a modification of the third embodiment of the fastener 1c according to FIG. 3, with the difference that here both grooves 4, 5 are angled from the rear 13 of the fastener 1e run inwards and end accordingly in an extension 16. The force-transmitting groove surfaces 17 and 18 are also shown in this embodiment in Fig. 5, so that the function is understandable without further description.

6 shows a further exemplary embodiment of a fastening element 1f, which differs from the previously described embodiments in that instead of two grooves, only a single groove 5a is provided, which extends vertically from the underside 11 of the fastening element 1f (based on the Position of use of the fastener 1f) extends through the fastener 1f and ends at a distance from the top 10 with a curved groove surface 18. The width of the groove 5a is smaller than the diameter of the lattice bars 2, 3, but the curved groove surface 18 at the end of the groove 5a is part of a groove extension, as shown in the drawing, and at the height of the lower lattice bar 3, the straight and even groove surfaces 17 curved groove surfaces 18a for receiving the lower lattice bar 3 in the position of use of the fastening element 1f.

When attaching the fastening element 1f to the grating, the fastening element 1f is guided like a clamp or fork over the upper grating bar 2 and, after a corresponding rotation into the grating plane, also over the lower grating bar 3 until the grating bars 2, 3 snap into place on the curved groove surfaces 18 or 18a, which may result in a press fit. A groove 25 on the upper side 10 results in a certain articulation effect, so that when the fastening element 1f is placed on the grating bar 2, the two fork halves of the fastening element 1f can be opened sufficiently until the grating bar 2 snaps into place. After snapping in particular on the lattice bar 2 can the fastening element 1f can only be detached from the latticework with appropriate finger pressure or the like.

After the shaft 6 of the supporting element has been fastened in the central section 8, there is an additional safeguard against inadvertent loosening of the fastening element 1f from the grid, because the shaft 6 extending through the fastening element 1f blocks the free passage in the groove 5a. Otherwise, this exemplary embodiment, as the drawing shows, corresponds to the previous exemplary embodiments, so that a more detailed description is dispensed with.

7 shows a preferred embodiment for the grooves 4, 5. In order to achieve a secure clamping fit of the different designs of the fastening element 1a, 1a ', 1b, 1c, 1d and 1e, the groove 4 or 5 initially has an inlet funnel 19 in cross section with a relatively large opening for easy insertion of the relevant lattice bar 2 or 3 on. The inlet funnel 19 opens into a circular section 21 in which the relevant lattice bar 2 or 3 is to be received. In order to facilitate the insertion of the bars 2 and 3 into the circular section 21, a continuous groove 22 is provided on the corresponding outside at the level of the circular section 21, so that the part 24 with a corresponding undersize of the rear part of the inlet funnel 19 during insertion of the lattice rod 2 or 3 can deflect resiliently, however, when the lattice rod 2 or 3 has reached its final position in the circular section 21, spring back and bring about a secure clamping fit, so that the fastening element only requires considerable force from the lattice rod can be solved again. This cross-sectional shape can be in Extrusion process in the manufacture of a strand, from which the individual fasteners are divided, very easily and accurately. Incidentally, it is equally applicable to straight grooves and to angular grooves without any fundamental difference.

FIG. 8 shows a preferred embodiment for the design of the bore or opening 23, which runs through this in all exemplary embodiments of the fastening element 1a-1f and is intended for receiving the shaft 6 of the respective support element. In order to achieve simple and secure anchoring of the shaft in the opening 23, this first has a straight annular section 23a on the side where the shaft 6 is to be inserted, and the section 23a corresponds in diameter to the shaft 6 or is only slight smaller, at least in such a way that the shaft 6 is also encompassed in the section 23a without play. Section 23a is followed by a conically narrowing section 23b, and this is followed by a straight section 23c, which is smaller in diameter than the diameter of section 23a. This design, in conjunction with the plastic leather properties, enables the shaft 6 of the respective support element to be inserted under pressure into the opening 23, expediently until a projection formed on the shaft 6 stops, for example a ring, so that the shaft 6 is in this position with it tight press fit is held by the narrowing opening 23.

Figures 9-11 illustrate that different types of support elements with a corresponding shaft 6 can be attached to the respective fastening element.
