[ 5 7 ABSTRACT A collapsible and portable signalling device including a collapsible support member and a foldable sign attached thereto. The collapsible support member includes a base member, intermediate telescoping members received within the base member and a supporting end member. One end of the foldable sign is attached to the base member and the other end is attached to the supporting end member so that in a collapsed position the sign ends are adjacent to and abut each other. Transverse and longitudinal fold lines are formed within the foldable sign so that it may be folded into a small portable package.

7 Claims, 5 Drawing Figures COLLAPSIBLE AND PORTABLE SIGNALLING DEVICE The present invention relates generally to improvements in signalling devices and, more particularly, it pertains to a new and improved signalling device which is collapsible and portable.

The general concept of collapsible signs and signalling devices is well known in the art. However, it has long been desirable to provide a collapsible signalling device which may be easily opened, used, and then collapsed or folded into a small portable package. Further, it would be desirable if such a collapsible signalling device be small enough to be conveniently stored in the users pocket or purse so that it may be carried with the user and employed wherever and whenever needed, yet large enough to provide a clearly noticeable sign. In addition, it has long been desirable to construct such a collapsible signalling device so that it may be economically manufactured and inexpensive enough to provide a practical and viable alternative to other types of signalling arrangements.

For example, in highly populated cities it has been difficult and, at times, dangerous for an individual to attract the notice of a taxi driver. More particularly, the individual is usually among a crowd of people and in order to be noticeable he must enter the street and wave his or her hand to signal approaching taxi drivers. However, the taxi driver frequently does not notice the waving individual until it is too late or, sometimes he is not noticed at all due to the surrounding crowd of people. Accordingly, it would be highly advantageous and desirable for such an individual to acquire an inexpensive signalling device which is both large enough to be noticeable and outstanding, and yet small enough to be conveniently carried and stored on the person of the user.

Accordingly, it is an overall object of this invention to provide a signalling device which fills these needs. More particularly, it is an object of this invention to provide an inexpensive signalling device which is large enough to be clearly noticeable at a distance. Further, it is also an object of this invention to provide a signalling device which may be easily collapsed and folded into a small package and conveniently stored and carried on the user.

Briefly, in accordance with the principles of the invention, a collapsible and portable signalling device is provided which includes a collapsible support member and a foldable sign fixedly attached thereto. The collapsible support member includes a base member, interrnediate telescoping members received within the base member and a supporting end member. One end of the foldable sign is attached to the base member and the other end is attached to the supporting end member so that in a collapsed position the sign ends are adjacent to and abut each other. The sign ends are formed by two or more layers of foldable material laminated to each other. At a point along the laminated ends of the sign, an opening is formed between the layers so that the base member may extend through the opening formed in one end of the sign and so that the supporting end member may extend into the opening formed at the other end of the sign. In this manner, the collapsible support member is fixedly secured between the laminated layers at each end of the sign.

When the collapsible support member is collapsed by telescoping the intermediate members into the base member, the foldable sign attached thereto must also be arranged or constructed so that it may be easily folded into a compact package which may be conveniently carried on the person of the user. To this end, the foldable sign has transverse and longitudinal preformed fold lines formed therein. In this manner, as the collapsible support member is contracted into its fully collapsed position, the user also folds the foldable sign along the transverse fold lines about an axis perpendicular to the collapsible support member to fold the sign on itself at least twice. After the collapsible support member has been completely collapsed and the foldable sign transversely folded, the foldable sign is then folded along the longitudinal fold lines about an axis parallel to the collapsible support member. The collapsible and portable signalling device may then be conveniently stored in any pocket or purse. To use the portable signalling device, the user merely unfolds the sign about the longitudinal and transverse fold lines and extends the collapsible support member to its fully extended position.

Accordingly, it can be seen that the present invention provides an inexpensive portable signalling device which may be easily actuated between a collapsed position and an extended position. Further, in its extended position the signalling device is clearly noticeable and outstanding while in its collapsed position it may be conveniently stored on the person of the user.

Further objects, features and advantages of the present invention will become apparent upon the consideration of the following detailed description of a presently preferred embodiment when taken in conjunction with the accompanying drawing, wherein:

FIG. 1 is a front elevational view of the collapsible and portable signalling device of the present invention in its fully extended position;

FIG. 2 is a rear elevational view, with parts cut away, of the present invention;

FIG. 3 is a perspective view of the signalling device of the present invention in an intermediate collapsed and folded position;

FIG. 4 is a perspective view of the signalling device of the present invention in a completely collapsed, but

partially folded configuration; and

FIG. 5 illustrates the signalling device of the present invention in its completely collapsed and folded position and ready for insertion into the pocket of the user.

Referring now to FIG. 1, the collapsible and portable signalling device of the present invention, which is generally designated by the reference numeral 10, comprises a collapsible support member 12 and a foldable sign portion 14 fixedly attached thereto. In FIG. 1, the signalling device 10 is illustrated in its completely extended and unfolded configuration and is ready for use. It should be understood that the foldable sign portion 14 may have any desired message printed thereon but, for the purposes of illustration, the signalling device of the present invention is illustrated as a taxi signalling device.

Referring now to FIG. 2, there is shown a rear elevational view of the signalling device 10 of the present invention. As may be seen most clearly therein, the collapsible support member 12 includes a base member 16 and a series of intermediate telescoping members attached to the base member 16 and adapted to be telescopically received therein. The collapsible support member 12 also includes a supporting end member 20 having a diameter approximating that of the base mem ber 16, so that when the collapsible support member 12 is collapsed, the supporting end member 20 will not be telescopically received within the base member 16, but will abut against the upper end 16a of base member 16.

The foldable sign portion 14 includes an indiciacarrying surface or face on each side thereof so that any desired message may be placed on either or both of the faces. The foldable sign portion 14 also includes a lower end 14a and an upper end 14b which are fixedly attached to the upper end 16a of base member 16 and supporting end member 20, respectively. The lower end 14a of foldable sign portion 14 is constructed in such a manner so that it may be easily attached to upper end 1611 of base member 16. More particularly, the lower end 14a includes two layers 14c, 14d laminated to each other by any suitable sealing means, such as an adhesive. In one particular form of the in vention, the lower end 14a is formed by simply folding a portion 140 of the foldable sign 14 about an axis 142 onto portion 14d and applying a suitable adhesive between the layers to form the desired lamination. An opening 14f is then formed in the fold axis 14s in order to form an opening wide enough through which base member 16 may be extended between layers 14c, 14d. A suitable sealing means is then applied to the upper end 16a of base member 16 so that it is fixedly attached and adheres to layers 14c, 14d.

A similar arrangement is employed to fixedly attach the upper end 14b of foldable sign portion 14 to the supporting end member 20. More particularly, an end portion 14g of foldable sign portion 14 is folded over onto portion 14h about a folding axis l4j in order to form two layers which may be suitably laminated to each other. In order that the supporting end member 20 may be placed between the two layers 14g, 14h and fixedly attached thereto, an area 14k between the two layers 14g, 14h are not laminated to each other. In this manner, a suitable adhesive is applied to supporting end member 20 so that it may be placed between layers 14g, 14h and fixedly attached at 14k.

In order that the signalling device may be folded into a small package, preformed fold lines or crease lines are formed in the foldable sign 14. In a preferred form of the invention,

transverse fold lines

22a, 22b, 22c and 22d are preformed in the foldable sign portion 14. In addition, longitudinal fold lines 22c and 22f are also preformed in the foldable sign portion 14.

Accordingly, as may be seen in FIG. 3, the signalling device 10 of the present invention is easily collapsed and folded into a small portable package. More particularly, as shown in FIG. 3, collapsible support member 12 may be fully collapsed by pushing base member 16 and supporting end member together so that the intermediate telescoping members 18 may be received within the base member 16. In its fully collapsed position, supporting end member 20 of collapsible support member 12 is adjacent to and abuts against the upper end 16a of base member 16. As collapsible support member 12 is collapsed, foldable sign portion 14 will fold over on itself about transverse fold line 22b. In addition, lower end 14a will be folded over onto foldable sign portion 14 about transverse fold line 22d. Accordingly, it should be clear, that when collapsible support member 12 is in its fully collapsed position,

lower end 14a of foldable sign portion 14 will be adjacent to and abut against upper end 14b of foldable sign portion 14, as may be seen most clearly in FIG. 4.

As may be seen in FIG. 4, the next step in the folding operation is completed by folding sign portion 14 over onto itself again about

transverse fold lines

220, 22c. Although FIG. 4 illustrates that signalling device 10 has been folded and collapsed into a relatively small package approximately 4 X 4 inches square, it may be still further compacted so that it may be easily and conveniently stored within a standard size pocket 24, as shown most clearly in FIG. 5. To complete the final folding operation, sign portion 14, as shown in FIG. 4, is folded behind itself about longitudinal fold line 22c. Sign portion 14 is then folded about longitudinal fold line 22f to form the compact package illustrated in FIG. 5. In order that the collapsed and folded signalling device 10 may be conveniently inserted into a pocket, such as a shirt pocket 24, and avoid movement or loss thereof, a suitable clip 16b is provided on base member 16 so that signalling device 10 may be attached to pocket 24.

When it is desired to use signalling device 10, it is merely unfolded about its longitudinal fold lines 22e, 22f and then unfolded about

transverse fold lines

22a and 220. Then, in order to completely unfold sign 14 about transverse fold lines 22b and 22d, collapsible support member 12 is opened to its fully extended position by gripping supporting end member 20 and forcing it away from base member 16. The user may then grip base member 16 and hold signalling device 10 in the manner illustrated in FIG. 1 so that sign 14 may be clearly observed.

From the foregoing, it will be appreciated that there has been provided in accordance with the present invention, an inexpensive signalling device which is large enough in its unfolded position to be clearly noticed and outstanding, yet is compact enough in its collapsed and folded position to be conveniently stored or carried on the person of the user.

A latitude of modification, change and substitution is intended in the foregoing disclosure and in some instances, some features of the invention will be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the spirit and scope of the invention herein.
