FLEXIBLE CLOTHING CLAMP STRUCTURE Filed March 25, 1966 5 Sheets-Sheet 3 United States Patent 3,350,754 FLEXIBLE CLOTHING CLAMP STRUCTURE Robert J. Ballenger and Robert G. Schaefer, Highland Park, Ill., assignors to Central Specialties Company, Chicago, 111., a corporation of Illinois Filed Mar. 25, 1966, Ser. No. 537,531 22 Claims. (Cl. 24255) This invention relates generally to clamp structures and more particularly to clamp structures which are particularly adapted to clampingly engage and thereby retain substantially flexible material, particularly fabric.

The clamp of the present invention generally can be used with any type of material, however, it is particularly adapted and is primarily intended for use to clampingly engage and thereby retain substantially flexible sheet material. In particular, the clamp can be advantageously used to hold fabric and clothing. It is in this latter respect that the clamp is superior to those presently available, for it may be used repeatedly without losing its resiliency and clothing can be supported by the clamp for a considerable period of time with generally little, if any, creasing. Accordingly, one or more of the clamps can be adapted to a hanger for storing or transporting clothing, particularly rnens trousers.

It is therefore an object of the present invention to provide an improved clamp. More particularly, it is an object to provide an improved clamp which is adapted to clampingly engage and thereby retain substantially flexible sheet material, such as fabric and clothing.

Another object is to provide an improved clamp for supporting a substantially flexible sheet material such as fabric and clothing in a fashion such that little, if any creasing results.

Still another object is to provide a clamp of the described type which may be used repeatedly over a considerable period of time with little, if any, loss in its resiliency and hence clamping action.

Still another object is to provide a clamp of the described type which is adaptable to be mounted to a flat surface or it may have a bracket aflixed to it for removably affixing the clamp to a door by hooking the bracket over the top edge of the door or it may be formed as an integral part of a clothes hanger which is adapted to be hung on a clothes pole within a clothes closet and the like.

A still further object is to provide a clamp which is simple in construction, having no moving parts.

A still further object is to provide an improved clothes hanger having as an integral part thereof at least one clamp of the above-described type.

Still another object is to provide an improved hanger having two pairs of clamps of the above-described type formed as an integral part thereof so that two articles of clothing, such as two pairs of mens trousers, can be supported by it.

Still another object is to provide an improved hanger having clamps of the above-described type formed as an integral part of it, and having a hook-like member whereby an article of clothing, such 'as a pair of mens trousers can be supported by the clamps and the trouser legs draped over the hook-like member so as to substantially reduce the space required to store the trousers. In this respect, the hanger is also particularly adapted for use in a suitcase for transporting articles of clothing, such as mens trousers.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction 3,350,754 Patented Nov. 7, 1967 hereinafter set forth, and the scope of the invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention, reference should be had to the following detailed description taken in connection with the accompanying drawings in which:

FIG. 13 is a top plan view illustrating a manner in which a hanger can be formed with two pairs of clamps of the type illustrated in FIG. 1, as an integral part there- 0 and FIG. 14 is a partial top plan view of one end of the hanger, illustrating an alternative manner in which the end of the locking bar can be formed to provide the locking tips.

Similar reference characters refer to similar parts throughout the several views of the drawings.

Referring now to the drawings, in FIG. 1 there is illustrated a clamp 10 exemplary of the invention having a clamp body 12 formed of a substantially U-shaped rod which has the ends of its two

arms

13 and 14 reversely folded so that each of the arms, when viewed from the side, as illustrated in FIG. 2, generally resemble an inverted J. The loop portion 16 of the clamp body 12 between the

arms

13 and 14 is preferably bent to extend angularly outward towards the ends of the

arms

13 and 14, in a manner described more fully hereinafter. A locking bar 18 which comprises a rod which. is bent to form a substantially pointed tip 20 and which has its opposite ends affixed to respective one of the

arms

13 and 14 in a fashion such that the tip 20 is centrally disposed between the two arms. The locking bar 18 may be afiixed to the backside of the

arms

13 and 14, as illustrated, or alternatively, it can be affixed to the front side of them. A coil spring 22 has its ends secured to the ends of the

arms

13 and 14 and is of a length so that it forms a loop which extends, preferably to a point just slightly above the loop portion 16 of the clamp body 12. The inside diameter of the coil spring 22 advantageously corresponds to the outer diameter of the rod forming the clamp body 12 so that the ends of the coil spring 22 can be secured to the ends of the

arms

13 and 14 by forcibly and frictionally urging them on to the ends. The tip 20 of the locking bar 18 preferably projects between the loop of the coil spring 22 or to a point just behind the coil spring 22, and the downwardly disposed ends of the

arms

13 and 14 are bent slightly inwardly so that the coil spring is slightly angularly disposed with respect to the vertical axis of the clamp 10.

A plate 24 having a pair of apertures 26 (shown in dotted lines in FIGS. 13) can be fixedly secured between the

arms

13 and 14 for affixing the clamp to a flat surface, by extending fastening means such as threaded screws through the apertures 26.

To use the clamp 10, the coil spring 22 is flexed or bent outwardly away from the clamp body 12 and the object to be clamped, such as the flexible sheet material 28, is placed behind the clamp against the tip of the locking bar 18, as illustrated in FIGS. 4 and 5, and the coil spring 22 released. It can be seen that the coil spring 22 forcibly urges the sheet material 28 about the pointed tip 20 of the locking bar 18 so as to effectively lock the sheet material between the coil spring 22 and the

arms

13 and 14 of the clamp body 12. Also, the looped end of the coil spring 22 engages and forcibly urges the sheet material 28 inwardly above the loop portion 16 and between the

arms

13 and 14 of the clam body 12 so that the sheet material generally drapes over the loop portion 16. It is found that the action of the coil spring 22 is effective to securely clamp the sheet material so that considerable effort is required to release the material, without releasing the tension of the coil spring. Furthermore, while the sheet material is firmly clamped and retained, the clamp causes very little, if any, creasing of the material, even after the material is clamped therein for considerable periods of time.

To further increase the effectiveness of the clamp in retaining objects clamped therein, the entire clamp is preferably coated with rubber or a similar material to provide greater frictional engagement with the object so that greater resistance is provided against the object being released. This coating may be advantageously applied by dipping the clamp, and, accordingly, the looped end of the coil spring 22 is preferably spaced from the loop portion 16 of the clamp body 12, as indicated above, so that the coating does not overrun and adhere the coil spring to the clamp body. A jet of air can advantageously be applied across the clamp at this point, after the dipping operation to viritually eliminate any possibility of this occurring. The coating applied to the clamp also functions to effectively seal and therefore fixedly secure the ends of the coil spring to the

arms

13 and 14 so that under normal circumstances or use, the possibility of the ends of the coil spring coming loose from the arms is virtually eliminated. A coating, such as rubber, is particularly desirable to provide secure clamping and retainment of glossy or similar type objects or material which offers, very little, if any, resistance to another object slidingly or clampingly engaged therewith.

The use of a coil spring is generally unique in an application of the above-described type inasmuch as coil springs are generally intended and used in applications wherein the coil spring is stretched longitudinally. Normally in such an application, a torsion spring would be used. However, it is found that the coil spring is extremely effective and is virtually immune to damage. When the coil spring 22 is bent to permit an object to be clamped beneath it, each of its coils flex and is working so that its tensional forces resisting the bending action is generally distributed throughout the length of the coil spring. This factor is particularly significant, particularly at the ends affixed to the

arms

13 and 14, since it permits the spring to be repeatedly bent without breakage occurring at these connecting points. In attempting to use a torsion spring, it is found that the springs fail at these points after the spring is bent a relatively few times. Also, this same factor permits the coil spring to retain its resiliency and therefore its clamping ability indefinitely.

In FIG. 6, the clamp 10 is illustrated affixed to a substantially U-shaped bracket 40 which is adapted to be hooked over the upper edge Of a door d e. li

The bracket 40 can have a width which substantially corresponds to the width of the plate 24, illustrated in FIG. 1, so as to provide a hook which will securely engage with the door. With this construction, it can be seen that the clamp 10 can be used in bedrooms or bathrooms to conveniently hang articles of clothing or towels and the like. In FIG. 7, a bar 42 is illustrated having a number of clamps 10 aflixed to it and a plate 44 having apertures 46 therein for fixedly mounting the bracket unit to a fiat surface and the like. In this case, the bar 42 can be bent to provide tips which correspond to the tip 20 illustrated in FIGS. 1-3 and the clamp body is afiixed to the rod so that the tips project between the loop of the springs, in the manner described above, Individual articles can be retained by respective ones of the clamps or the article can be retained by means of all of the clamps, simultaneously.

In FIG. 8 there is illustrated a hanger 48 including a rod 50 which is affixed to another rod 52 and which has its one end bent to provide a hood 54 which is adapted to hang over a clothes bar and the like. The opposite end of the rod 50 extends perpendicularly to the bar 52 a short distance below the bar 52 and is then angularly dis posed at an angle of approximately 30 and then again reversely bent to extend parallel with the bar 52. The pair of clamps 10 are aflixed to the opposite ends of the bar 52, and the bar 52 is bent to provide a pair of tips corresponding to the tips 20 of the locking bar 18. As described above, the body portions 12 of the clamps 10 are aflixed to the bar 52 so that the tips project between the loop portion of the coil spring 22, in the manner described above.

The hanger 48 can be advantageously used to hang a pair of mens trousers, in the manner illustrated in FIGS. 9 and 10. In these figs., it can be seen that the top of the trousers 58 are clampingly engaged by means of the clamp 10, in the manner described above, and the pant legs of the trousers can be folded and draped over the horizontally disposed end 56 of the rod 50. The hanger 48 is ideally suited for hanging trousers in a closet, for the trousers are securely retained on the hanger by means of the clamps 10 so that there is very little likelihood of them becoming unhooked from the hanger and, furthermore, since the pant legs are folded and draped over the horizontally disposed end 56 thereof, the pant trousers require no more room than a pair of shorts. This feature also permits trousers to be suspended on clothes bars which are disposed in vertical, spaced relationship, one on top of the other. For the same reason, the hanger 48 is ideally suited for use in conjunction with a suitcase since the pant trousers can be compactly folded and secured on the hanger, within the suitcase.

The hanger 48 is also ideally suited for use in depart ment stores for displaying mens trousers, for the trousers are securely clamped and held by the clamps 10 thereon and require little storage space since the trouser legs can be folded and draped over the horizontally disposed end 56 of the bar 50. Since the hanger is adapted to clampingly engage the top end of the trousers, labels 60 and 62 indicating the price, size and like information concerning the trousers are disposed so that they can be easily read and observed by anyone interested in purchasing the trousers. Also, the fact that the trousers can be clampingly engaged 'by the clamps for a considerable period of time without being creased adds considerable value to their use for this purpose.

The hanger 48 can also be coated with rubber or similar material, in the manner described above, to offer greater frictional surfaces and hence resistance to th trousers accidentally being removed.

A hanger 64 is illustrated in FIGS. 11 and 12 which has a clamp 66 formed as an integral part of it and which is adapted to hang larger articles or to, for example, hang a pair of mens trousers by the pant cuffs rather than the top of the trousers, as in the case of the hanger 48 illustrated in FIGS. 9 and 10. The clamp 66 is like the clamp 10 illustrated above, however, the clamp body 68 is substantially larger in width than the clamp body 12 and the coil spring 70 is correspondingly lengthened to provide a loop when affixed to the ends of the

arms

72 and 73 of the clamp body 68. The clamp body 68 is fixedly secured to a rod 74 which functions as a locking bar and also the support member for the hook 76 afiixed to it. Since the clamp body 68 is substantially wider in width, the locking bar 74 preferably has offset bends formed in it to provide a pair of

tips

78 and 89 which are disposed with respect to the coil spring 70 and the lower portion of the clamp body 68, in the manner described above. With this construction, it can be seen that larger articles and particularly the cult portion of mens trousers can be clampingly secured to the hanger .64.

In FIG. 13, there is illustrated a hanger 82 which may be like hanger 48 illustrated in FIG. 8, however, the hanger 82 has a pair of clamps affixed to each of its two pposite sides so that, for example, two pair of mens trousers can be hung on the hanger. In the case of the hanger 82, a bar 84 has each of its ends bent to function in the manner of the locking bar 18 of the clamp and the clamp bodies 8588 are fixedly secured to the bar 84 in alignment with the tips 90 formed therein. It may be noted that the bar 84 is bent in a fashion such that on each of its opposite ends a pair of tips 90 are formed to extend on one side of the bar 84 while only a single tip 90 extends on the opposite side thereof. In FIG. 14 there is illustrated an alternative manner in which the ends of the bar 84 may be formed to provide two centrally disposed, oppositely extending tips 92. In this case, the ends of the rod 84 are reversely folded and bent so as to provide the tips 92 and the

clamp bodies

94 and 96 are fixedly secured to the rod 84 so that the tips 92 are disposed with respect to the coil springs 98 and 99 in the manner described above.

It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efiiciently attained and, since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
