Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a hook device that is to be mounted on an exterior surface, usually flat, such as an undersurface of a table, counter, bar top, gaming machine, shelf, cabinet or building structure wall where the hook device is to be used for suspending an item therefrom.

2. Description of the Related Art

Hook devices have long been in use for supporting personal items such as clothing, purses, umbrellas, backpacks, belts, scarves, tools, cables, towels and gadgets. The hook device comprises a U-shaped hook that protrudes outwardly from the surface on which it is mounted. When the hook device is not being used, the hook becomes a hazard capable of tearing clothes of a human or causing injury. It is desirable to have the hook retracted when not in use to eliminate this hazard and also to improve appearance avoiding the unsightly look of the not used hook. There have been designed previously numerous different types of retractable hook devices. However, these prior art devices have been complexly constructed and therefore expensive to manufacture.

It is desirable to construct a retractable hook device which is simple in construction and can optionally be installed either with adhesive or mechanical devices such as screws or nails.

It is further desirable to construct a retractable hook device which can be manufactured inexpensively and therefore sold to the consumer at an inexpensive price.

SUMMARY OF THE INVENTION

A retractable hook device that is to be attached to a vertical, inclined or horizontal surface to be used to support personal items such as by a strap extending from the personal item. The hook device includes a housing which has an internal enclosed chamber. The hook device has a hook that has an inner end and an outer end. The outer end is basically U-shaped. The inner end is straight and is located within the internal enclosed chamber. Mounted on the inner end is a protuberance. A release plate is mounted on the housing which has a main body that is located within the internal enclosed chamber and an enlarged end (actuator) that extends exteriorly of the housing. The main body has an internal opening. The enlarged end is designed to be manually contacted to cause inward sliding movement of the release plate which is to disengage the detent established by a protrusion mounted on the release plate in conjunction with the protuberance which will permit the hook to move between an extended position located transverse to the housing to a retracted position located alongside the housing. When the hook is in the retracted position and the enlarged end is released from manual contact the protrusion again abuts against the protuberance functioning as a detent to lock the hook in the retracted position.

DETAILED DESCRIPTION OF THE INVENTION

Referring specifically to the drawings there is shown in FIGS. 1 to 5 the retractable hook device 10 of this invention. Hook device 10 has a metal or plastic housing 12. Housing 12 has a back surface 14. Back surface 14 is to be attached in some conventional manner to an exterior structure (not shown). Conventional manner of attachments could be by adhesive, screws or nails. Housing 12 can assume any desirable shape with generally an elongated rectangular configuration being preferred. Housing 12 is also to be as thin as possible so when the device 10 is not being used it is to be obscure.

Housing 12 has an internal enclosed chamber 16. A rectangularly shaped opening 18 is provided within the upper end 20 of housing 12. A release plate 22 is slidingly mounted within opening 18 in a close fitting relationship movable from an outer position shown in FIGS. 4 and 5 to an inner position (not shown). However, the position of the release plate 22 in FIG. 4 is different from that of FIG. 5 (moved some intermediate distance toward the inner position). Release plate 22 has an upper surface 24 on which is mounted protrusions 26, 28, 30 and 32. Protrusions 26 and 28 function as a movement limiter defining the position of the release plate 22 in the outward direction (shown in FIG. 5) where the protrusions 26 and 28 abut against the wall of enclosed chamber 16 that is located closest to upper end 20. Protrusion 32 connects with an elongated coil spring 34 with protrusion 32 functioning into continuous aligned contact between coil spring 34 and release plate 22. Coil spring 34 is mounted within cavity 36 formed within housing 12. Release plate 22 has an internal opening 38 which is rectangularly shaped. Release plate 22 has an enlarged outer end 40 which may be referred to as an actuator.

U-shaped hook 42 has an access opening 44 formed within its outer end. Hook 42 is normally constructed of metallic rod material. Hook 42 has an inner end 46 which is basically of a straight configuration where the outer end of hook 42 is curved. Inner end 46 is conducted through hole 48 formed on one side of housing 12 and through an aligned hole (not shown) formed in an opposite side of housing 12. Lock washer 50 functions to longitudinally restrain the inner end 46 relative to housing 12. The hook 42 is capable of pivotally moving relative to housing 12 between a retracted position shown in FIG. 4 and an extended position shown in FIG. 5. In the retracted position the hook 42 is located in substantial longitudinal alignment (alongside) with the housing 12. In the retracted position the hook 42 is located substantially transverse to housing 12. In this position an article or item (not shown), such as a piece of clothing, umbrella handle, strap of a purse, etc. could be inserted through access opening 44 to be supported by the hook 42.

Fixedly mounted on the inner end 46 is a protuberance 52. Protuberance 52 has a first flat surface 54 and a second flat surface 56. When the hook 42 is in the extended position (FIG. 5), the second flat surface 56 abuts against protrusion 30 which functions as a detent to lock in place the hook 42. When the user pushes on enlarged outer end 40 (indicated by arrow 64) and moves release plate 22 compressing spring 36 with this movement being sufficient to disengage second flat surface 56 from the protrusion 30, hook 42 will be automatically pivoted due to the bvias of coil spring 58 mounted on inner end 46 and connecting with housing 12 to the retracted position in direction of arrow 60. The connection between flat surface 56 and protrusion 30 is as a detent. When the hook 42 is in the retracted position, the protrusion 30 abuts against first flat surface 54 again forming a detent locking the hook 42 in position. When it is desired to again move the hook 42 to the extended position, the user just presses on enlarged outer end 40, which is now in the outer position, sufficiently to release protrusion 30 from first flat surface 54, which is now in the inner position, which will the permit the user to manually pivot the hook in the direction of arrow 62 to the extended position.
