Description
    RELATED APPLICATIONS
  • [0001]
    This non-provisional application claims priority from provisional application No. 60/754,662, filed on Dec. 30, 2005, the disclosure of which is incorporated herein by reference in their entirety.
  • FIELD OF THE INVENTION
  • [0002]
    This invention relates generally to a coil clip for clamping garments and, more particularly, to a garment hanger clip provided with improved construction for preventing deformation and for ease in manufacturing and manipulation.
  • BACKGROUND OF THE INVENTION
  • [0003]
    The present invention relates to a structural improvement of “Coil Spring Hanger Clip” disclosed in the U.S. Pat. No. 6,023,819. A problem of the coil spring hanger clip disclosed in the above U.S. patent is resided in that either the fixed jaw or the movable jaw of the clip has an asymmetrical and unbalanced construction, thus leading to asymmetrical application of the force to each jaw. This cause deformation and mismatch of two jaws after use over a period of time.
  • [0004]
    The clip disclosed in the above U.S. patent also involves the following particular disadvantages:
  • [0005]
    (1) the asymmetrical and unbalanced construction of the clip has rather difficulty in injection molding during the manufacturing thereof and inevitably results in an additional problem of being relatively expensive to manufacture;
  • [0006]
    (2) the clip requires for a heavier coil spring and a high force applied to the clip and spring is required to manipulate the clip; and
  • [0007]
    (3) there is a tendency for the delicate and smoothly textured garments to accidentally or unintendedly release or drop off from the jaws of the clip because of the deformation of the clip and of the design of teeth at the bottom of inner surfaces of the jaws.
  • [0008]
    Accordingly, there exists a need for an improved clip with a simple design which is inexpensive to produce in an injection mold and which is capable of surely and stably holding garments, especially holding expensive and delicate garments.
  • SUMMARY OF THE INVENTION

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0031]
    Referring firstly to FIG. 1 of the drawings, there is illustrated a garment hanger 10 comprising a hanger arm 12, from which a hook member 14 projects upwards in the middle. Positioned at both ends of the hanger arm 12 are clips 20 constructed consistent with a first preferred embodiment of the present invention, to which a garment can be securely clamped. The garment hanger 10 may be of any size, shape and configuration that is conventional in the clothing industry. Preferably, the garment hanger 10 used in the present invention is advantageously of a type having a plastic post 16 integral with the hanger arm 12 and a hook member 14 made of metal and received in the post 16. The plastic material may be preferably selected from PP, HIPS and K-resin. As is known in the industry, the hanger 10 may also be formed as a one-piece moulding of plastic material.
  • [0032]
    The clip 20 comprises a first jaw 22 (hereinafter referred as fixed jaw) integrally moulded with one end of the hanger arm 12, a second jaw 24 (hereinafter referred as movable jaw) that pivots with respect to the fixed jaw 22, and a coil spring 26 held between the fixed jaw 22 and the movable jaw 24 to serve as a biasing means of the clip 20 for holding and releasing an garment, as best seen in FIGS. 2 to 4. Each of the jaws 22, 24 may be made as a single piece of molded plastic.
  • [0033]
    Referring now to FIGS. 5 to 7, the fixed jaw 22 is symmetrically formed with two arcuate portions 32 outwardly, upwardly and inwardly extending from an inner surface of the fixed jaw 22 with a uniform size and configuration. The two arcuate portions 32 are provided in a spaced and aligned fashion to define two open-end supports 40. The lower ends of the arcuate portions 32 are joined by a ledge 34 which extends outwardly from the inner surface of the fixed jaw 22. The ledge 34 serves as a stop to prevent the coil spring 26 (usually being V-shaped, as shown in FIG. 13) from being pressed too far downwardly during its insertion between the jaws. For the sake of supporting the ledge 34, a projection 36 extends downwardly from the underside of the ledge 34 along the inner surface of the fixed jaw 22. A groove 38 is built on the upper inner surface of the fixed jaw 22 for receiving a first leg of the coil spring 26. The groove 38 is also used for supporting the coil spring and preventing it from moving or slipping. Arranged on the lower inner surface of the fixed jaw 22 are rows of raised teeth 62 formed substantially perpendicularly to the inner surface of the fixed jaw 22 in order to improve the clamping action of the clip 20.
  • [0034]
    Referring to FIGS. 8 to 10, they show a moveable jaw 24 for use in combination of the fixed jaw of FIGS. 5 to 7. The movable jaw 24 is symmetrically formed with a pair of stub shafts 42 outwardly, laterally and oppositely extending from an inner surface of the movable jaw 24 with a uniform size and configuration. The two stub shafts 42 are spaced apart so that they define a space 58 adapted for suitable accommodation of the coil spring 26, as shown in FIG. 4. The stub shafts 42 are constructed to fit the dimensions of the portions 32 on the fixed jaw 22 so as to allow engagement therebetween. In this embodiment shown, the stub shaft 42 includes a support 46 and an arcuate pin 44 axially extending out from the support 46. The two arcuate pins 44 are configured so that they can be pivotally received in the open-end supports 40 of the fixed jaw 22 through the opening of the supports 40 in this manner to form a pivot axis about which the movable jaw 24 is pivotally mounted to the fixed jaw 22. Reinforced ribs 56 may be positioned above the stub shafts 42 to afford-additional support.
  • [0035]
    Similar to the fixed jaw, a ledge 48 is also provided which extends outwardly from the inner surface of the movable jaw 24 to join the stub shafts 42 and functions in a manner same as the ledge 34 provided on the fixed jaw 22. For supporting the ledge 48, a projection 50 extending downwardly from the underside of the ledge 48 along the inner surface of the movable jaw 24 is disposed.
  • [0036]
    Two parallel vertical ribs 52 are built on the upper inner surface of the movable jaw 24 to form a slot 54 for better guiding and receiving a second leg of the coil spring 26. One of the ribs 52 may be formed as an extension of the stub shaft 42, which the other rib 52 is arranged adjacent to and parallel with to form the slot 54, as best seen from FIG. 8. It is obvious that the ribs 52 of relatively large size can provide a stronger resistance in response to the force applied to the clip in order to open the clip and release the garment.
  • [0037]
    The lower inner surface of the movable jaw 14 has rows of slightly upward raised teeth 64 at an angle of about 80 degrees with respect to the longitudinal axis of the movable jaw 14, as shown in FIG. 10. The teeth 64 on the movable jaw 24 can be arranged to offset from those 62 on the fixed jaw 22 to create interengagement. The design of the teeth 64 formed on the movable jaw 64 in accordance with the present invention allows for stably clamping garments between the jaws of the clip.
  • [0038]
    The movable jaw 24 is pivotally mounted to the fixed jaw 5 and the hanger arm 12 of the garment hanger by respectively inserting the stub shafts 42 of the movable jaw 24 into the open-end supports 40 of the fixed jaw 22. The jaws 22, 24 are biased together by disposing the coil spring 26 into the space 58 defined by the fixed and movable jaws 22, 24 along the slot 54 formed on the movable jaw 22 and the groove 38 formed on the fixed jaw 22. The coil spring 26 can be readily pushed downwardly to seat in place, with its first leg received in the groove 38 on the fixed jaw 22 and its second leg received in the slot 54 on the movable jaw 24. The coil spring 26 may be easily fitted either by hand or by a suitable means.
  • [0039]
    In this embodiment, the clips 20 disposed at the ends of hanger arm 12 are substantially mirror images of one another, centred about the middle of the hanger arm. In particular, the grooves 38 and the slots 54 of the two clips 20 are mirror-inverted, as shown in FIG. 14.
  • [0040]
    FIGS. 11 and 12 illustrate a fixed jaw and a movable jaw consistent with a second embodiment of the invention. This embodiment is substantially similar in structure and operation to that disclosed in the first embodiment, but differing only in that the clips disposed at the ends of hanger arm 12 are made as a same configuration rather than as a mirror-inverted configuration. In other words, this embodiment offers an advantage of the obviation of necessity to distinguish the jaw as the right one or the left one either for the fixed jaw or for the movable jaw, when in use or manufacturing process. As can been seen in FIG. 12, the stub shafts extend downwardly to form two additional ribs 68 as an alternative of the projection 50 for providing supporting action.
  • [0041]
    In operation, the clip 20 is normally closed. Pressure of a user's fingers on the movable jaw 24 overcomes the force of the coil spring 26. This causes the clip 20 to open for securing a garment due to the pivot arrangement of the two jaws. When the pressure is released, the coil spring 26 moves the jaws back to the closed position so that the garment is stably secured by the clip 20.
  • [0042]
    As discussed above, a significant feature of the invention is the construction of the symmetrical uniform outwardly, upwardly and inwardly directed portions 32 and the stub shafts 42 respectively arranged on the fixed and movable jaws to thereby eliminate the unbalance and deformation problems, which was not accomplished by the prior art garment hangers. This feature greatly prolongs the service life of the clip.
  • [0043]
    In addition, such a symmetrical and uniform construction also offers the convenience of mass-manufacturing the clip using molding with one mold or two structurally similar molds, the clip thus being manufactured at very low cost which should contribute to its popularity and usefulness. According to the invention, the coil spring in a relatively small size may be used while maintaining the clamping action. The utilization of a lighter spring allows the ease for assembling the jaws or manipulating the clip through the less thumb pressure exerted against the movable jaw.
  • [0044]
    Further, the garment clip in accordance with the present invention is developed with the teeth on the jaw slightly inclining upward to form an angle of about 80 degrees with the longitudinal axis so as to prevent the undesirable release of a garment.
  • [0045]
    It is understood that many other embodiments of the present invention are also possible, and many corresponding modifications as well as variations can be made by those skills in the art as according to the disclosure of the present invention and without departing from the spirits and essentials thereof, while such modifications and variations fall into the scope of the claims of the present invention.
