Description

MODULAR PANTS HANGING UNIT
Brief Summary of the Invention BACKGROUND
This invention relates to a hanger for one or more pairs of pants, in particular, it relates to 1o a pants hanger having a stationary arm and a spring or springs biased against said arm to provide pressure for gripping a pair of pants between the spring or springs and the arm.
Numerous types of pants or trousers hangers have been disclosed over a long period of time. U.S. Patent 707,192 issued to Aiken describes a trousers supporter having parallel rods.
The spacing between two rods is barely sufficient to receive the four thicknesses of the trousers material but not wide enough to receive eight thicknesses of material which occurs at the seam portion at the extreme end of the trouser legs. Since this hanger is not adjustable, it is limited to certain trousers with a specific material thickness. This limitation makes this type of hanger unsuitable with the wide variety of materials and thicknesses now available.
U.S. Patent 2,492,325 to Schroeder describes a combination hanger comprised of 2o plurality of spaced parallel arms. The arms are spaced to receive the cuffs of men's trousers between an adjacent pair, however other garments can be draped over the arms as well. Since the arms are fixed with respect to each other, this pants hanger suffers from the same limitation as the above pants hanger with regard to the intended method of supporting pants. As to draping garments over the arms, the lack of a gripping arm requires careful balancing of the garment over the arm to prevent the garment from sliding off and falling to the floor, where it will inevitably become wrinkled or soiled.
U.S. Patent 4,557,407 to Bogaczyk describes a pants hanger having parallel bars in which a pair of pants are held between a pair of bars by the friction force between the surface of bars and pants. This technique is very sensitive to the fabric materials or fabric thickness and is likewise 3o not suitable for hanging wide variety of pants.
U.S. Patent 853,527 to Tye discloses a trousers hanger with a plurality of fingers proximally mounted to a plurality of corresponding pins which are parallel to each other and vertically disposed, enabling the distal end of each finger to swing horizontally. The distal ends of the first and last forgers are urged together by a compressed spring between the extended 3s proximal ends of the two forgers on the opposite side of the pins. Since only the distal ends of the fingers are compressed together, this hanger does not provide a pressure along the length of the forgers. As a result, the weight of the pants pulling on one side can pull and stretch the pants material with undesirable results.
U.S. Patent 2,127,333 to Hall et al. discloses a garment hanger with a plurality of pairs of forgers. Each pair of forgers are connected at a proximal end to each other and are free at the distal ends. Furthermore, the free ends of each pair are compressed together by a bolt and nut adjacent the proximal end of the gripping fingers. This patent suffers from the same disadvantage as the previous patent, in that only the distal ends of each pair are compressed together, which can result in misshaped pants due to uneven stretching and pulling of the fabric.
U.S. Patent 5,607,066 to Hebberd discloses a pants rack assembly having two rigid outer 1o fingers and two floating inner forgers which are pressed against the outer fingers by two springs disposed between them. The springs are supported by an additional spring support arm disposed between the two inner fingers. This patent can support two pairs of pants between two forger gripping members but it requires a middle spring support arm which increases manufacturing costs and thus increases the price of the assembly. Additionally, the presence of the two coil springs prevent a person from draping a garment, such as a skirt, necktie, or other item, over one of the inner fingers. If several of these assemblies were to be placed next to each other, it would be difficult to figure out which fingers are stationary and which fingers are floating to determine which way drape the article of clothing.
Accordingly, none of the prior art hangers provide a simple construction for providing pressure along the length of a supporting arm to grip a garment. It is therefore an object of this invention to provide a pants hanger which simplifies the pants hanging process and suffers from none of the disadvantages of the prior art. It is another object of the invention to provide a modular hanging unit that can be easily assembled into hanging array for hanging and draping multiple pairs of pants. It is also an object of the invention to provide an integrated hanging rack for hanging and draping multiple pairs of pants. It is yet another objective of this invention that extend the above mention objectives to hanging skirt, neck tie and other items. It is finally an object of this invention to provide all of the features in a device which is inexpensive to manufacture.
3o SUMMARY
The embodiments disclosed in the present application are directed towards pants hangers which obtain a gripping force by biasing a spring or springs between two stationary arms. The spring or springs serve both as a guide during the insertion of a garment between the two stationary arms and as a source of gripping pressure, thereby reducing the complexity and manufacturing costs.

In a first embodiment, a plurality of springs formed from spring wire are mounted to a first stationary arm and gently curves out to apply pressure against a second stationary arm. The shape of the spring provides a smooth guide for inserting garments between the two arms for hanging, but also maintains the garments in position by gripping them between the spring and the second stationary arm.
Each Spring element may be attached at one end to the first stationary arm, having a single resilient biasing region, or it may be attached at both ends to the first stationary arm and have two resilient biasing regions on either side of the contact region which functions to grip and hold the garment in place.
The remaining embodiments provide for various shaped flat metal springs which serve the same function and operate in substantially the same way as the formed wire springs. The flat metal springs provide a greater surface area of contact against the garment, which permits more evenly-distributed pressure, which reduces the likelihood of damage to a garment due to stretching and pulling of the fabric. Secondly, the flat metal springs may be cheaper to produce ~s due to fewer steps in manufacturing.

io Detailed Description of the Preferred Embodiments The first embodiment of the invention is shown in Figures 1 through 4. Figure 1 shows the invention according to the first embodiment in top down, or plan view. The invention comprises a pants hanger having a common block 10 from which two fixed parallel arms 11 and 12 extend.
The invention would work equally well if these two arms were reversed, serving each others' functions, e.g., if the invention were to be turned upside-down. Left arm 12 has two spring elements 30 mounted to it. Arms 11 and 12 are formed integrally with common block 10 but need not be.
2o Each spring element 30, shown separately in side view in Figure 2 and top view in Figure 3, are formed from a single piece of spring wire, and include two mounting terminals 31, two torsion spring sections 32, and spring arm 33. Terminals 31 fit into terminal receiving channels formed into arm 12 and torsion spring sections 32 fit over posts 35 formed into arm 12. Receiving channels may be simply holes into which terminals 31 extend, or grooves formed in the upper and lower surface of arm 12. Torsion springs 32 fit snugly into torsion spring coil housing cavity 17.
Posts 35 are shown in profile in Figure 2 for clarity, but may be integrally formed in arm 12 or eliminated altogether. When smaller spring wire size is used, posts 35 add additional mechanical support to coils 32.
Each spring 30 is biased in an "open" condition shown in Figure 3, but is compressed 3o slightly by arm 11 when installed onto arm 12. Each spring 30 includes contact region 34 which is biased against arm 11 when installed. Contact region 34 gripes an article of clothing slipped between arms 11 and 12 to support the article in a hanging condition. When clothes are present between arms 11 and 12, springs 30 are placed in a compressed condition as shown in Figure 4, and the free ends of springs 30 may be forced into respective cavities 16 formed into the body of arm 12. Cavities 16 permit the springs to deform to such an extent that the springs provide nearly as much clearance between the springs themselves and arm 12 as would be if the springs were not present at all between arms 11 and 12 without sacrificing the gently curving shape of springs 30 which allow clothing to be easily inserted and removed past spring elements 30.
Figures 5 and 6 show a second embodiment according to the invention. This embodiment is similar to the previous one, except that spring elements 40 are formed from stamped, flat metal springs instead of spring wire. Flat metal springs 40 provide a greater area of pressure against an article of clothing supported by them than do spring wire springs 30 of the previous embodiment.
Springs 40 are formed in the same basic shape as springs 30 in the previous embodiment, but due to their simpler structure, they are easier to manufacture and attach to arm 12 of the hanger unit.
1o Each spring 40 includes a mounting terminal 41 which is embedded into hanger arm 12, a substantially U-shaped resilient biasing region 42 which takes most of the bending stress when the spring is deformed, contact region 43 which serves to compress an article of clothing against arm 11, ramp region 44 to prevent bunching or jamming when removing an article of clothing, and spring end 45, which always remains in contact with arm 12, also to provide for easy removal of the article of clothing.
Figures 7, 8, and 9 show a third embodiment according to the invention. In this embodiment, a single spring is employed which extends a majority of the length of arm 12. The single long spring element with two resilient biasing points 55 provides even greater surface contact area and more uniform pressure against a garment than previous embodiments and is 2o assembled with fewer parts.
Spring 50 includes recess region 51 at about the mid-point along its length which lines up with recess region 13 formed in arm I1 of hanger unit 10. The recess regions 13 and 51 are designed to accommodate the seams on pants legs which are usually found at about the mid point between creases. Spring 50 is shown in perspective view in Figure 8, and it is formed from a single piece of stamped flat metal spring, and it includes two terminals 53 and 54, two substantially U-shaped resilient biasing regions 55, two ramp portions 56, and two contact regions 52 formed on either side of recess 51. Terminal 53 is embedded in left arm 12, and is therefore fixed in place. Contact regions 52 and recess portion 51 may be stiffened by being bent along both edges or by being corrugated lengthwise to minimize bending under pressure. If formed from 3o plastic, the contact regions 52 and recess portion 51 may be stiffened by having ribs formed and extending along the side opposite arm 11. U-shaped bend 55 and ramp portion 56 located adjacent to terminal 53 and the U-shaped bend 55 and ramp portion 56 located adjacent to terminal 54 assert substantially independent biasing force toward right arm 11 and apply uniform pressure against the right arm 11 through contact regions 52. Spring 50 flattens out when compressed, and 3s terminals 53 and 54 are urged away from each other as shown in Figure 9.
Because of this, terminal 54 slides part way out of its slot 18 but is still retained by the slot when spring 50 is compressed as shown in Figure 9. Ramps 56 permit a garment to be smoothly inserted and removed without undue pulling, jamming, or stretching on the garment.
Figure 10 shows a variation on the previous embodiment in which a plurality of spring elements, each having two substantially U-shaped resilient biasing regions, are provided along the length of the hanger. This embodiment shows that a majority of the benefits derived from the previous, single-spring embodiment can also be enjoyed by employing more than one spring. In particular, a large surface area of compression to grip the garment, a relatively even distribution of pressure against a garment, easy insertion and removal of the garment, etc.
Springs 50 each 1o have two ends 54 and 53, which may both slide freely inside their respective slots 19, or may have one free end and one fixed end as the spring 52 shown in Figures 7 through 9.
The orientation of the hanger is not material to its utility as a hanger for garments. If very long garments are required to be hung in a space not tall enough to accommodate the full length of the garments, it may be desirable to rotate the hanger 90° as shown in Figure 11 and drape the I5 garment over the lower arm. While Figure 11 shows the hanger shown in Figure 7 at a different angle, any hanger disclosed herein may be rotated for a similar effect. In fact, any hanger according to the invention will operate substantially the same regardless of the angle at which it is rotated.
Each hanger embodiment disclosed herein may be arranged in an array of hangers, where 20 each hanger is but one module of many. Each hanger module can be mounted to, or formed integrally with, a common support as shown in Figure 12.
Figure 13 shows a plurality of hangers according to the embodiment shown in Figure 10 wherein each support arm may be formed integrally with common block 10 or they may be mounted to common block 10. In this example, each support arm except the outer two are 25 common to adjacent hangers. Thus each support arm, except the outer two, serve both as a spring support for one hanging unit on one side and a gripper surface for another hanging unit on its other side. In this way a plurality of closely spaced units can be easily fit into a small space.
A person of ordinary skill may certainly envision other enhancements or alterations to the embodiments set forth above without departing from the spirit and scope of the invention. For 3o example, the hanger bodies and springs may be formed of varying materials.
Plastic springs, for example, may be used in place of metal wire or flat metal springs. The hanger bodies may be formed of ceramic, wood, glass, or metal instead of plastic. Composite plastic may be desired for the hanger body. The modularity of the hangers can be improved by providing snapping fixtures to permit them to be snapped together to create any size array of hangers to fit any available space.
35 The hangers may be mounted for rotation along a vertical axis at their bases to permit easy viewing of the hung garments to select among them. The hangers may be mounted to a vertical pole for display purposes, or to satisfy other requirements of the available space.
Having now particularly described the preferred embodiments of the invention, it is understood that the scope of protection sought is not defined by the detailed description set forth s above, but by the claims appended hereto.
