Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to key lock covers and more particularly pertains to a new Protection Device For Key Lock Openings for preventing moisture and dirt from entering key locks. 
     2. Description of the Prior Art 
     The use of key lock covers is known in the prior art. More specifically, key lock covers heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements. 
     Known prior art key lock covers include U.S. Pat. No. 4,282,732; U.S. Pat. No. 4,825,673; U.S. Pat. Des. 333,083; U.S. Pat. No. 3,861,182; U.S. Pat. No. 4,090,379 and U.S. Pat. No. 4,858,454.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new Protection Device For Key Lock Openings embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, it will be noted that the Protection Device 10 for key lock openings comprises a cap 20 and a one-piece handle and clip assembly 30. 
     As best illustrated in FIGS. 1 through 4, it can be shown that the device 10 is utilized with key operated locking mechanisms, such as those on cars and trucks. As best shown in FIG. 3, a car or truck includes a lock mechanism 14 with a key hole 16, affixed to an exterior panel or surface 18 of the vehicle. 
     The device 10 includes a cap 20 which is sized to fit around the lock mechanism 14. The cap 20 includes an exterior convex surface 21, an interior concave surface 22, and a bottom surface 23, to give the cap an overall dome-shaped appearance. The bottom surface 23 is made flat so as to closely engage with the panel 18. The cap is made of rigid plastic material. 
     Extending from the concave surface 22 is a sealing ring 24. The ring 24 is sized such that it surrounds the locking mechanism 14, and so that it extends past the bottom surface 23 of the cap 20. This provides increased sealing effect when the bottom surface 23 is disposed in contact with the panel 18, thus preventing moisture from entering the locking mechanism 14. The sealing ring is made of a flexible rubber material, such as foam rubber. 
     One-piece handle and clip assembly 30 is affixed to the cap 20. The cap is preferably molded around the assembly 30 during formation of the cap, so as to integrally attach the cap and assembly. The assembly 30 includes a loop-shaped handle 31 which extends from the convex surface, and a clip 32 extending from the concave surface. The loop of the handle is sized so as to permit at least one finger to be inserted into the loop for pulling on the handle. Preferably more than one finger can fit within the loop for increased pulling force. 
     The clip 32 is sized such that it can fit within the key hole 16 of the lock mechanism 14. The clip 32 is also magnetized. Since the lock mechanism is normally made of metal, the attraction force between the magnetized clip 32 and the metallic components of the lock mechanism keeps the clip 32 inside of the key hole 16, and thus secures the device in place. The clip is magnetized to an extent such that the attraction force keeps the device firmly in place during use, but permits a person to remove the device by pulling on the handle 31. 
     It should be recognized that the handle and clip do not need to be of one-piece construction. A separate handle and clip could be used and appropriately attached to their respective surfaces. 
     FIG. 4 shows an alternate embodiment for use with a different type of locking mechanism. Some vehicle panels 18a include a recess 19 therein, with the locking mechanism 14 and key hole 16 disposed at the bottom of the recess 19. The recess might cause the clip to fit loosely within the locking mechanism and not be securely engaged. FIG. 4 shows a protection device which is similar in all aspects to the device 10, but it includes a frusto-conically shaped rubber plug 26 which extends from the concave surface of the cap and is molded about the upper end of the clip 32. The plug 26 fits closely within the recess 19 and prevents shifting of the clip and cap due to the recess. 
     In use, the lock to be protected is chosen and the device is attached by inserting the clip within the key hole. The clip is inserted until the bottom surface 23 contacts the panel 18. The bottom surface of the cap contacting the panel, and the sealing ring 24 engaging the panel, form a series of seals preventing moisture from entering the lock. The magnetic force between the clip and the metallic elements of the lock keeps the device in place. The device is simply removed by grasping the handle 31 and pulling with a force sufficient to overcome the magnetic attraction force. 
     As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
