The device includes, as a single integral part molded from a plastic material, a pair of clamping members, a flexible web joining these members and serving as a hinge, a latch to lock the members in closed position and a hook by which the device can be suspended. The arrangement of the various features of the device is such that the device can be molded in a twopart die without the use of cams or similar devices to permit release of the molded part from the die.

25 Claims, 16 Drawing Figures MOLDED GARMENT CLAMP BACKGROUND OF THE INVENTION This application is related to my application entitled Garment Clamping Hanger" Ser. No. 18,130 filed on Mar. 10, 1970.

The invention is a one-piece molded plastic clamp having a pair of side members joined along one edge by a flexible web serving as a hinge. The opposite edges of the side members are free and, when the clamp is closed, are designed to grip an article placed between them. Between the free ends and the flexible web, the side members are spaced apart even when the clamp is closed. The clamp is made of a resiliently deflectable material whereby these side members may be deflected under pressure before they are latched together to create clamping pressure on the article. One of the side members has a latch and the other a keeper which, when engaged, lock the side members in clamping or closed position. The clamp also includes a supporting hook which is also integral with the side members to permit the device to be hung from a suitable support such as a rod or a bar. The entire device is designed to be manufactured by injection molding as a single piece in a simple two-part die because it lacks reentry shapes which would otherwise lock it in the mold.

Clamps for hanging all types of objects particularly small objects have been known for many years and have a wide variety of uses. They have been made from numerous materials including metal, wood and plastic. This invention, however, is intended to provide a clamp which supplies a need that has not heretofore been satisfied by existing devices. It is specifically intended to be capable of such inexpensive manufacture that it can be used and discarded. Examples of such use would be the display of hosiery, gloves, ties, scarves and similar clothing articles in a store or to hang film negatives during development. The invention provides a clamp which is sufficiently economical that it may be given away with the article when the article is sold. Further it is intended to do this yet provide, in a single integral part not only means to grip and thus support the article but means by which the article can be suspended for display. This is particularly important in connection with articles such as gloves, hosiery and ties which are more readily seen by the potential purchaser if they are displayed while suspended rather than piled one upon another on a shelf or counter. Further, because this device is particularly designed for molding from plastic, the material will cause no damage to the article such as rust, cutting or transfer of any decorative surface coatings. Because the invention permits the entire unit including its supporting hook to be made as a single part without further finishing operations or the assembly of separate components, this device can be manufactured for a fraction of existing devices presently'on the market.

DESCRIPTION OF THE PREFERRED EMBODIMENT A clamp incorporating the principles of this invention is illustrated in FIGS. 1 through 4. As can be best understood from FIG. 3, theentire clamp structure 10 is a single part comprising a body 11 having a pair of

sides

12 and 12a integrally joined by a thin flexible web orhinge 13. Anaperture 14 is provided generally centrally of the body 11 and extends into both of the clamping or

side members

12 and 12a Within theaperture 14 is ahook 15. one end. of which is integral with theside member 12a. The rest of the hook is separated from theside member 12 by anarrow gap 16. At one end of theaperture 14 is alatch 17 extending inwardly of the clamp. The latch is best seen in FIGS. 1, 2 and 4. Thelatch 17 may have one ormore teeth 18 designed to engage and lock with the opposite edge of theopening 14 which in this particular construction, forms thekeeper 19.

It will be observed from FIGS. 1, 2 and 4 that each of the

side members

12 and 12a, between theweb 13 and their free ends, is arched away from the other and that this arching is sufficient to substantially space the side members even when the clamp is closed and the free ends are pressed together firmly (FIG. 1). At the apex of the arch the

side members

12 and 12a are preferably reinforced byribs 20. Thekeeper 19 may also be reinforced by across rib 21 which can incorporate acamming surface 22 to guide thelatch 17 as it is moved into locking position (FIG. 5). The ability of the clamp to grip an article can be increased by the provision of grippingteeth 23 on the free ends of the

side members

12 and 12a.

It will be observed from FIGS. 3, 4 and 5 that the clamp can be molded in a two-part mold without the use of cams, with the mold-halves opening and closing in the direction of the arrows A and B (FIG. 4). It will be seen that in such an arrangement there are no such undercut or reentry structures aswill prevent the part from being removed from the mold when the mold is opened. Yet the part, as removed from the mold, is complete and requires no further work whatsoever to prepare it for its final use. It will be noted that the hook is erected simply by folding the

side members

12 and 12a into their operating position. It will also be noted that thelatch 17 will automatically engage thekeeper 19 as the side members approach clamping position. By the provision of more than onetooth 18 on the latch the clamp can be made to exert the requires gripping pressure on articles of various thickness.

It is contemplated that this invention will be manufactured by injection molding. In this type of molding it is particularly important that the molds or dies be as simple as possible. The addition of cams or other movable parts to the mold materially increases product cost because it lengthens the molding cycle, substantially increases initial mold cost and significantly decreases mold life. It also frequently decreases the number of cavities which may be incorporated in each mold.

A number of synthetic resinous materials may be used for this product. Resins particularly suitable for the manufacture of this product include polypropylene, polyethylene and nylon. The material must provide a part in which theside members 12 and l2aare resilient and may be slightly deflected. In this manner when the clamp is closed the arch in the sides may be slightly flatten thus building up clamping pressure and assuring a positive lock between thelatch 17 and thekeeper 19. When so deflected the sides when released must spring out firmly to assure the locking effect between the latch and the keeper and to assure retention of the desired clamping pressure. It must also be capable of providing theweb 13 serving as the hinge and withstand repeated flexing without fatigue.

FIG. 6 illustrates a slight modification of the clamp shown in FIGS. 1 through 5. In this arrangement the latch 17a instead of simply bridging the distance between the two side members is extended beyond theside member 12a to form a manipulation arm orpad 24. By pressing on this pad the latch can be caused to release when it is desired to open the clamp. It will be understood that this is merely a further extension of the same invention.

FIGS. 7, 8 and 9 illustrate a further modification of the invention shown in FIGS. 1 through 5. In thisclamp 30 theside members 12nd 12a remain the same. Thelatch 17b has, in addition to theteeth 18, amanipulation pad 31. The pad is designed so that it overlies a portion of the central aperture 32 in the clamp. As such it does not require any cams to accommodate it to the mold. Thus, it is suitable for molding in a two-part die.

The hook a is again integral with theside member 12a but instead of lying in the plane of theside member 12 it is inclined out of this plane sufficiently that when the clamp is closed the plane of the hook is centered about the vertical center line of the clamp as seen in FIG. 7. Once again this can be done because the hook lies entirely within that portion of the opening 32 which is in theside member 12. It will benoted that thepad 31 can be inclined with respect to thelatch 17b sufficiently to make it parallel to the adjacent face of the clampingmember 12 when the clamp is closed.

FIG. 10, 11 and 12 illustrate a further modification of this invention. In thisclamp 40 the edges of theside members 12b and 12c adjacent the flexible web or hinge are formed into flanges extending inwardly of the clamp. These flanges position the web 1311 away from the plane of the side members. Thus, when thesides 12b and 12c are folded about theweb 13a to their normal operating position, the sides are spaced apart. Further in this arrangement it will be noted that theflange 41 has a raisedridge 42 designed to engage thestop shoulder 43 on the flange 41a. As the clamp is closed, this engagement occurs before the free ends of theside members 12b and contact each other. This interference between theridge 42 and the. stopsurface 43 stretches thehinge web 13a, giving the side members a slight bias to spring apart, assuring a locking grip between the latch and its keeper when the clamp is fully closed.

It will be also noted that thehook 15a is integral with theside member 12b at the end of theflange 41. Thus it is offset from the plane of the adjacent portions of both of theside members 12b and 120 and when the clamp is closed the hook will be pivoted into an erected position basically centered on the vertical centerline of the clamp.

As is clearly shown in FIG. 11, thehook 15a lies entirely within that portion of theopening 45 which is I within the side member 120. Thus, it does not interfere with the use of a two-part mold.

Another difference in this clamp is the fact that the keeper 19c consists of an inwardly projecting finger having a plurality ofteeth 46. The latch has amanipulation pad 47 and asingle tooth 44. Again the clamp may be closed about materials of varying thickness because the provision of theseveral teeth 46 on the keeper 19c permits this selection of closing positions. It will be noted that when the clamp is closed both the keeper and the latch are confined within the silhouette of theclamp 40. Againribs 20a are provided to reinforce theside members 12b and 12c. The fact that theteeth 42 on the keeper 19a and thetooth 44 on the latch require a small undercut in the die does not destroy this fact since the material is somewhat resilient and the size of the teeth is such that the teeth may be caused to release from the mold due to slight deflection of the part itself.

FIG. 13 illustrates the fact that this invention can be practiced in a clamp in which only one of the side or clamping members is arched. In theclamp 60, theside member 61 is straight and theside member 62 only is arched. Thelatch 63 is integral with theside member 62 and thekeeper 64 is integral with theside member 61 and is formed within the outline of the side member FIGS. 14, 15 and 16 show a further modification of this invention in which the supporting hook, as molded, circumscribes one of the side members rather than being circumscribed by it. Theclamp 70 has a pair of side or clamping

members

71 and 72 joined by a flexible web orhinge 73. Ahook 74 has one end integral with theside member 72. The main body of thehook 74 largely surrounds theside member 71 and is separated from it by agap 75. While the side or clamping members and the hook are illustrated as substantially circular in configuration, it will be recognized that numerous other shapes could be employed. Also it will be recognized that the shape of the hook need be the same as that of the side members, so long as the hook and the side member it inscribes are separated by a gap. Thus, for example the hook may be generally circular when the side member is generally rectangular or keystone in shape.

Acentral aperture 76 extends across thehinge 73 into both the

side members

71 and 72. At one end of the aperture 76 alatch 77 is integral with theside member 72 and projects inwardly of the clamp, as the parts of the clamp appear when closed. Thelatch 77 has a finger ormanipulation pad 78 on its free end when overlies or is within the outline of theaperture 76 as the clamp appears when fully open (FIG. 14). Thepad 78 is generally parallel to the general plane occupied by the

side members

71 and 72 and thehook 74 when the clamp is fully open as illustrated in FIG. 14.

The latch has one ormore teeth 79 designed to engage thekeeper tooth 80. The keeper is formed at the end of theaperture 76 opposite from thelatch 77. The keeper preferably includes acamming ramp 81 to facilitate engagement of the .latch.

It will be observed from FIGS. 15 and 16 that the

side members

71 and 72 are convex or outwardly disked. This provides the necessary spacing of the side members at the latchto permit effective latching and positive article gripping pressure. In all embodiments it is optional whether small teeth, serrations or similar gripping surfaces will be provided on the inner faces of the free ends of the side members. Whether or not such are provided does not change the principles of the invention.

In all of the several embodiments of the invention which have been described, the flexible web or hinge is created by reducing the wall thickness of the plastic. In all cases it is molded of the same plastic as the remainder of the body of the clamp. In all embodiments the side or clamping members are resiliently deflectable within a limited range. This is important to assure both positive engagement between the latch and the keeper and adequate clamping pressure on the articles to effectively grip them. Thus, the plastic material used for the manufacture of this invention must not only be suitable for injection molding, but it must, in a wall thickness of about 0.0625 inch, have significant resistance to deflection yet in a wall thickness of about 0.02 have the characteristic of being both flexible and fatigue resistant.

In all embodiments the invention must be so designed that the entire product can be manufactured as a single, integral part. This must be accomplished by simple, two-part molds which do not have any cams or movable sections to release any reentry portion of the product.

While a preferred embodiment and several modifications of this invention have been illustrated and described, it will be recognized that other modifications of this invention may be made.
