BACKGROUND OF THE INVENTION1. Field of the Invention
This invention relates to the clothing industry and, particularly to garment hangers and, more particularly, to molded plastic hangers with improved clothes clip having a relocated biasing force for the bottom of the plastic hanger. Further, this invention relates to an improved spring clip, particularly though not exclusively for providing a biasing force in the improved clothes clip of this invention for the suspending of clothes (e.g. trousers and skirts) during shipment or for display or storage.
2. Description of the Related Art
For many years, various types of hangers in different shapes and sizes have been used to support all different types of clothing, including coats, jackets, shirts, pants and other articles of clothing. In many instances, there will be some type of hanger clip on the bottom portion or rod of the hanger in order to hold skirts, pants and other articles of clothing that cannot be draped over the top of the hanger. Among the various hanger clips that have been used are the ones shown in Morrish (U.S. Pat. No. 4,878,276), Gau (U.S. Pat. No. 5,052,085), Abdi (U.S. Pat. No. 5,075,935), Hunter (U.S. Pat. No. 5,241,728), Santapa (U.S. Pat. No. 5,402,558), Zuckerman (U.S. Pat. No. 5,890,634), Blanchard (U.S. Pat. No. 5,934,525), Wong (U.S. Pat. No. 6,023,819), Petrou (U.S. Pat. No. 6,050,462), Bond (U.S. Pat. No. 6,119,906), Zuckerman (U.S. Pat. No. 6,202,906), and Wong (U.S. Pat. No. 6,305,586). The problem with all of these hanger clips is that they use teeth or directly opposed ridges to increase the gripping ability of the clip. Thus, the puncturing by the teeth or high point pressure can damage the more delicate fabrics used in clothing today.
There are several prior art hangers with clips using a U-shaped biasing spring to apply pressure to the gripping surfaces of hanger clips, such as Petrou (U.S. Pat. No. 6,050,462), Zuckerman (U.S. Pat. No. 6,202,906), Morrish (U.S. Pat. No. 4,878,276), Abdi (U.S. Pat. No. 5,075,935), Blanchard (U.S. Pat. Nos. 5,915,605 and 5,934,525), Santapa (U.S. Pat. No. 5,402,558), Shang (U.S. Pat. No. 6,023,818), Willinger (U.S. Pat. No. 6,098,254), Bond (U.S. Pat. No. 6,119,906) and Batts (U.S. Pat. No. 6,422,438). The problem with all these hanger clips and U-shaped biasing spring itself is that the spring operates on the gripping legs of the hanger clip and does not extend very far down the surface of the legs. This provides an ineffective biasing force, which allows the biasing spring to become useless over time as the clip stretches with each use and eventually does not return to a tightly closed position.
While the plastic hangers noted above do achieve various design goals, such hangers nevertheless suffer from one or more drawbacks, such as complexity of construction, difficulty of assembly, limited utility, limited durability and ruggedness, and the like.
These hanger clips are important to secure the clothes to the hanger. As described above the problem with current clothes clips is that the biasing means used to grip the clothing fatigues, reducing the effectiveness of the hanger clip to hold the clothes, thereby causing the clothes to fall on the floor. Expensive or delicate clothing that falls from the hanger clip can be wrinkled soiled or even damaged, rendering them difficult or impossible to sell. In a home environment, the problem is exacerbated, as the clothes may become wrinkled or soiled such that the garment cannot be worn without ironing, pressing or dry cleaning.
In addition, it is common for clothing manufacturers to ship clothing on hangers. Hangers with bottom clips are often used to secure skirts, pants and other articles of clothing during transit. When the clips loosen or fail, the clothes fall out of the grips of the hanger during shipment. This causes the garments to be soiled, wrinkled and, in some cases, damaged. These conditions have been a plight to manufactures and retailers causing not only the extra labor of replacing the garments on the hangers, but the extra cost of cleaning and pressing the garments to make them saleable or potentially the cost of returning unmerchantable goods to the manufacturer or other source.
Further, the advent of new delicate and “slippery” man-made materials used in garment manufacture (microfibres, modal etc) and the increasing use of extremely “slippery” existing fabrics (such as silk) has lead to new gripping requirements for bottom hanger clips. It is not always desirable to use sharp ridges, spikes or points (teeth) on the inside of the jaws of the clothes clip to securely grab the fibers of the garment, due to the damage those types of holding mechanisms cause to the appearance of the garment. There is a new industry requirement to have increased holding power exerted on the garment by other non destructive means. By means of having the legs of the U-shaped spring clip extend the full length of the surface of the handle end of the hanger clip, increased force can be applied to the opposing gripper end of the hanger clip to allow pressure to be applied more evenly across the garment clip interface. This combined with the offset of the ridges on the grip portion of the hanger clip creates greater holding power with less damage to the garments, as compared to the standard prior art U-shaped spring clips, whose legs stop mid way down the jaw face of the clip.
Therefore, there is a need in the industry for a simple, easy to use, inexpensive hanger clip and U-shaped biasing spring that exerts enough force to hold clothing during storage, display or transit, and is not affected by the natural fatigue of the biasing spring caused by repeated use so that the hanger clip will continue to hold clothes securely.
Another need exists for a hanger clip which can retain the “slippery” fabrics in use today without damaging the delicate nature of such fabric.
SUMMARY OF THE INVENTIONTherefore, it is an object of this invention to provide an improved hanger clip and biasing force, which will not loosen and will maintain a greater uniform pressure on the gripping end of the clip for the entire useful life of the hanger. An additional object of the invention is to permit greater retention of today's “slippery” fabrics without damaging the delicate threads.
This and other objects of the invention are obtained by an improved bottom hanger clip having a biasing force applied to the handle of clip, which provides increased force and a more evenly applied pressure at the gripping face of the improved hanger clip.
The improved hanger clip uses interlocking ridges on the gripping legs to “trap” clothing as opposed to gripping the threads of the material. Further, application of the biasing force in the basic form of a U-shaped spring to the handle legs to hold the legs open during use, and therefore the gripping faces closed, allows the application of sufficient force to the gripping faces of the clip more efficiently allowing greater force at rest with less susceptibility to fatigue. Finally, the indented shape of one of the legs of the U-shaped spring allows the spring to open about the pivot of the hanger clip, thereby preventing binding when operated. Adding a ridge to the opposite leg allows retention of the spring in the clothes clip without require undue design features in the molding of the clip.
It can also be appreciated by those skilled in the art that these and other objects of this invention will become more apparent in the detailed description of the invention and thus the scope of this invention should not be restricted only to these objects.

DETAILED DESCRIPTION OF THE INVENTIONIt should be understood that in the various Figures, like reference characters refer to like components.
Thebasic hanger10 can be of any size, shape and configuration that is standard in the industry or required by the size/weight of the garment. In the preferred embodiment, theunitary body12 is a one piece integrally molded I-beam type unit with opposing hanger clips20 at either end, and made of a reasonably strong, semi-rigid plastic, such as styrene-butadiene. Such plastics are manufactured by Phillips 66 under the Trademark K-RESIN and by BASF under the trademark SYROLUX. Any other materials that are accepted in the industry for making plastic hangers may be used. As well, the hanger of this invention may work as well if made from wood, metal or a composite material. Further, theunitary body12 may have an open frame or wire type construction where the hanger clips20 may be attached so as to be repositionable along the lateral axis of the hanger.
In addition to theunitary body12 thebasic hanger10 would have ahook14, as is known in the industry. Thehook14 may be made of any suitable wire stock or other metal. Plastic may be used, particularly, where it is integrally molded with theunitary body12.
As another embodiment for use with open frame or wire style hangers the hanger needs to have a bottom flange, beam or rod on which one or more hanger clips20 may be positioned. Usually, a hanger of this type will include two repositionable clips offset from the center, but the invention will work without regard to the number of hanger clips. One, two or three or more clips may be incorporated.
Each of the hanger clips on each side of the hanger would be constructed in exactly the same manner. Thus, only one illustrative hanger clip will be described herein.
As is usual with hanger clips, this hanger clip has two centrally joined levers, such as to pivot with respect to each other, creating a gripping jaw on one end, in order to hold garments, and handles on the other end, which when pressed together, release the pressure of the gripping jaw. In the preferred embodiment, onemember22 is stationary or fixed where thehandle leg28 is made integral with the hanger, however, in other embodiments themember22 may be attached to the lower beam, flange or rod of an open hanger so as to be repositionable along the beam, flange or rod. Thesecond member24 pivots about thefirst member22 at acentral axis16 in thetransition region32 to create a functioning clothes clip when its top or handleleg38 is pressed toward thestationary leg28 ofmember22. A biasing force, such asU-shaped spring26, holds thehandle legs28,38 of the hanger clip apart in a normal position to create a closing or gripping pressure on thegripping jaw end30,40 of the members to securely hold an article of clothing. Outside pressure on thehandle legs28,38 overcomes the force of the biasing U-spring26 to open the gripping jaw ends30,40 of the hanger clip to release the clothing.
In order to better support this hanger clip, it is preferable that the hanger be of I-beam construction12 or that the lower flange, beam or rod of the hanger have a flat cross-section. In the preferred embodiment the top or handleleg28 of the fixedmember22 is made integral with thebeam12, as is known in the trade; and, the opposite end of themember22 defines agripping leg30, which will engage the clothing. Atransition region32 between thehandle leg28 and thegripping leg30 includes twoparallel supports34, each defining aseat36, which mates withpin46 onmember24.
Themovable jaw24 has a top or handleleg38 and agripping leg40 at its other end. Thetransition region42 between the two legs contains anopening44. Apin46 extends across opening44 such to mate withseat36 insupports34 ofmember22.
In the preferred embodiment, the fixed orstationary member22 is integral with thehanger12 and made as a single piece of molded plastic. Further, in the preferred embodiment themovable member24 is made as a single piece of molded plastic.
To pivotally connect the two jaws, they are overlaid—one over the other, so that thepin46 ofmember24 rests in theseat36 on thesupports34 of themovable jaw22. Thus, the jaws pivot about theaxis16 of thepins46, as is known in the trade.
The biasing force consists of aU-shaped spring26 and may be any gauge metal composite or other material that may used for springs in clothes clips. The particular gauge and material will depend on the force required by the spring to exert a needed pressure at the gripper jaw of the hanger clip.
As shown, thespring26 is disposed so that it resembles a “U” which contains abend48 offset from thebase49 of the “U” and oriented about thesame axis16 as thepin46 ofmember24 about which themembers22,24 pivot with respect to each other. The twolegs50,51 of the spring are such that oneleg50 extends from thebend48 and exerts a uniform force on the top or handleleg38 ofmovable member24, and theother leg51 extends frombase49 and exerts a uniform force on the top or handleleg28 of fixedmember22. The twolegs50,51 of the spring exert force so as to hold the top or handlelegs28,38 in a normally open position. This has the effect of holding the gripper jaw formed by grippinglegs30 on fixedmember22 andgripper leg40 onmember24 together or closed so as to hold garments. The shape of thespring26 is critical as without thebend48 which places thepin46 on the outside of thespring26, the spring would constrict on thepin46, thereby binding the clip and thus rendering it difficult or impossible to use.
Theindented bend48 mating withpin46 generally holds thespring26 in place. Opposite thebend48 is aridge54 running perpendicular to theleg51. This ridge further prevents movement of thespring26 during use of theclip20. To better support thespring26 and to prevent it from moving or slipping, anedge lip54 may be employed on the top or handle leg ofmember24. Additionally, ribs may be placed on the top or handle legs of the members which extend the length of the interface betweenleg50 andmember24 and ofleg51 andmember22 so as to contain the lateral movement of the spring as well. Further, anedge lip29 may also be placed on the stationary or handleleg28 ofmember22 to prevent slipping or moving of thespring26 in relation to that leg.
It may be appreciated that thespring26 may be shortened and need not run the entire length of the top or handle legs ofmembers22,24 or may be widened at the top to contain more surface area. However, the preferred embodiment, which, is designed for increased uniform pressure at the gripper legs of22,24, uses such maximum length as is practical. The key point is that preferred design and location of the biasing U-shaped spring in the hanger clip permits a greater and more uniform pressure at the jaw of the clip without binding on thepin46.
In operation, the clothes clip is normally closed. Pressure of a user's fingers on the top or handleleg38 of themovable member24 and the fixed ortop leg28 ormember22 overcomes the force of the spring and moves the top or handlelegs28,38 of the members together. Due to the pivot arrangement of the two members, this action causes the grippinglegs30 and40 of the members to separate. The user then places an article of clothing between thegripping legs30 and40. When the top or handle ends28 and38 are released by the user, the spring moves thejaws30 and40 back into position and the clothing is held securely between thegripping legs30 and40. To release the clothing, the user again applies pressure on the top or handlelegs28 and38 as heretofore, and the clothing can be removed from between thegripping legs30 and40.
To improve the gripping action of thegripping legs30,40, raisedridges60 are employed. Theseridges60 are offset so as to not contact the opposing ridge when closed. This causes the clothing to “snake” through the alternating ridges so as to permit today's “slippery” garments to be held with little or no damage to the delicate threads.
Gripping pads may be employed to enhance the slip resistance of the gripping faces. To affix the pads one could utilize direct molding of the pad to the members, any suitable mechanical means, or just use an adhesive. Another way to affix the pads is to provide projections on the pads which fit into recesses or openings on the gripping legs. One version uses projections with arrow shaped heads that extend into slots. Cylindrical and rectangular shapes may also be used. Generally, the pads may be made of a tactile material, such as rubber; however, any material with good anti-slip qualities is preferred.
Hangers with these clothing clips are typically made in standard 8″, 10″, 12″ or 14″ widths. Softer or harder springs may be used, depending on the thickness or bulkiness of the clothes to be held by the hanger. For heavy weight trousers or skirts, a heavier gauge spring may be desirable. For light summer clothes and bathing suits, a much lighter gauge spring would be used, so as to not damage the more delicate clothing.
Thus, there is shown and described a unique design and concept of a hanger clip and improved biasing force for that clip. The particular configuration shown and described herein relates to a preferred embodiment. While this description is directed to a particular embodiment, it is understood that those skilled in the art may conceive modifications and/or variations to the specific preferred embodiment shown and described herein while still remaining within the scope and spirit on the invention. Any such modifications or variations which fall within the purview of this description and ensuing claims are intended to be included therein as well even if not specifically described. The description herein is intended to be illustrative only and is not intended to be limitative.
