FIELD OF INVENTION

The present invention relates to demountable brackets for electronic accessories and more particularly to demountable brackets which are provided with locking means.

DESCRIPTION OF THE PRIOR ART

Demountable brackets for auto tape players and similar accessories for motor vehicles and the like have commonly included a pair of mating, engageable bracket members, one intended to be fixedly mounted to the auto, and the opposing bracket intended to be mounted to the player. Demountable brackets may be fastened to the respective auto and player by a variety of fastening means, such as bolts, rivets, and welds. Demountable brackets for auto tape players may also be provided with locking means. Commonly, the locking means employs various types of shackles and hasps engageable through the mating bracket members. These demountable brackets, having mated bracket members and locking shackles, may be costly and complicated, without adding to the structural strength and security of the locking bracket. In practice, it has been found that the bracket member, mounted to the tape player, may impair the use of the tape player for purposes outside the automobile, such as remote tape playing; and may impair the appearance and performance of the tape player itself.

Accordingly, it is an object of the present invention to provide locking, demountable bracket means for auto electronic accessories, which employ a fixedly mounted bracket means and a locking lattice independent of the electronic accessory.

It is a further object of this invention to provide demountable bracket means which is visually inaccessible and which may be conveniently locked and unlocked with a key.

These and other objects shall become apparent from the description following, it being understood that modifications may be made without affecting the teachings of the invention here set out.

SUMMARY OF THE INVENTION

Generally, the car stereo expansion locking kit comprises a plurality of cornerposts operable to closely, slidably receive a car stereo, or the like, and having a plurality of horizontally cut lattice receiving slots, a locking lattice including a plurality of rectilinear and transverse lattice strips pivotally mounted at intervals to each other to form a parallelogram and including a pair of diagonally disposed, slot-engaging leaves fastened at diagonal corners of the locking lattice, and a lock operable to selectively lock the locking lattice into the slots of the cornerposts.

A more thorough and comprehensive understanding may be had from the detailed description of the preferred embodiment when read in connection with the drawings forming a part of this specification.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a left front perspective view of the car stereo extension locking kit of this invention shown with the parts thereof exploded away for illustrative purposes, including a car stereo player shown in broken lines for illustrative purposes.

FIG. 2 is a bottom plan view of the locking lattice and lock of this invention shown as it would appear in its unlocked position.

FIG. 3 is a bottom plan view of the apparatus of the FIG. 2 shown as it would appear in the locked position.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the drawings and more particularly to the FIG. 1, the car stereo expansion locking kit of this invention is shown to advantage and generally identified by the numeral 10. The expansion lock 10 comprises a plurality of cornerposts 11, a locking lattice 12, and a lattice lock 13. The cornerposts 11 may be fabricated of angle iron-like members, and may be fastened upstandingly to a vehicle (not shown) by means of bolts, rivets and the like (not shown) engageable through bolt brackets 11' provided at the interior corner at the uppermost terminal end of each of the members 11'. Each of the posts 11 are fastened with their vertical corners disposed away from the geometrical center of a substantially rectangular region which is operable to closely receive a car stereo 14 and similar accessory equipment. A plurality of horizontally cut, distally disposed slots 15 are provided from the vertical corner edge into the side walls of the cornerposts 11.

The slots 15 are operable to engage locking leaf portions 16 of the locking lattice 12. The locking lattice 12 comprises a plurality of rectilinear lattice strips 17 and 17' and transverse locking strips 18 and 18'. A pair of rectilinear lattice strips 17 and a pair of lattice locking strips 18 are parallelly, pivotally fastened to the respective terminal ends of each of the strips 17 and 18. The rectilinear middle lattice strip 17' is pivotally fastened at its terminal ends midway on the transverse lattice strips 18; and the transverse middle lattice strip 18' is pivotally fastened at its terminal ends midway on the rectilinear lattice strips 17 and at its midpoint to the midpoint of the middle lattice strip 17'. Thus, it may be seen that the locking lattice, comprising the lattice strips 17, 17', 18 and 18', is operable to form a pivotally fastened parallelogram. The locking leaves 16 are fastened at a pair of diagonal corners of the pivotally fastened intersects of the lattice strips 17 and 18. The locking leaves may have a pointed configuration operable to engage suitable horizontal pairs of the slots 15 of the cornerposts 11. It is to be understood that while all the cornerposts 11 are provided with slots 15, the expansion lock 10 of this invention may be satisfactorily fabricated with slots 15 included in a pair of diagonal cornerposts 11.

The lattice lock 13 is intended to selectively lock the lattice 12 into a predetermined locked juxtaposition. The lattice lock 13 comprises a body member 19, a pair of dogs 20, and a cylinder 21. The dogs 20 are a pair of substantially C-shaped members, and are carried opposingly to each other on the body member 19. The locking dogs 20 are actuated and locked by means of a substantially commonly known locking cylinder 21 disposed between the dogs 20 in the body member 19. The lattice lock 13 is operable to lock the lattice 12 by engaging the intersect of the lattice strips 17' and 18' on a geometrical diagonal perpendicular to the diagonal of leaves 16.

In operation, a car stereo 14 may be slidably disposed within the cornerposts 11. As shown in the FIGS. 2 and 3, the locking lattice 12 is conformed to a substantially rectangular configuration and is disposed adjacent the lowermost terminal side of the car stereo 14. The lattice lock 13 may be disposed diagonally at the intersect of the strips 17' and 18' with the edges 20 disposed in their outermost position. The lattice 12 may then be conformed into a parallelogram with the locking leaves 16 disposed through a suitable, horizontal slot 15 in each of a diagonal pair of cornerposts 11. By actuating the locking cylinder 21 and simultaneously locking the dogs 20 to their closed position, the lattice 12 is secured into a locked, substantially stable configuration beneath the car stereo 14.

Having thus described in detail a preferred apparatus which embodies the concepts and principles of the invention and which accomplishes the various objects, purposes and aims thereof, it is to be appreciated and will be apparent to those skilled in the art that many physical changes could be made in the apparatus without altering the inventive concepts and principles embodied therein. Hence, it is intended that the scope of the invention be limited only to the extent indicated in the appended claims.
