Description

' . ~~ . : he FIELD OF INVENTION

The invention relates to the field of anti-theft devices for automobiles; specifically, a locking device for automobile gear levers.

BACKGROUND

One of the types of locking devices for automobile gear levers which is generally used, is a device that attaches the lock to the body of the automobile. This .

Jock has two (2) holes in which a u-shaped locking pin is inserted. The locking pin is : placed so as to surround the gear lever, wherein each of the pin legs are inserted into the holes of the lock to prevent the gear lever position from being shifted. However, : 15 this type of locking device, in spite of being made from steel can be sawn off, It does not effectively protect an automobile from theft, as it may be easily destroyed or unlocked. In terms of appearance, after installation, the components of this type of device are easily visible. - OBJECT OF THE INVENTION : :

The object of the invention is to provide an anti-theft device, which is different from commonly used gear lever locks, and affords more effective : automobile theft prevention. This device is installed inside the gear console, so as to maintain the interior appearance of the car. : :

SUMMARY OF THE INVENTION

According to the present invention there is provided an anti-theft device for automobile including a component adapted to be fitted to a gear lever or gear arm of the automobile, said component having a hole for insertion of a retractable plunger, said retractable plunger coupled to a movable lock cylinder slidably located ina casing adapted to be affixed to said automobile within the gear console of said automobile. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT :

The automobile anti-theft device of the preferred embodiment consists of two (2) parts, specifically, the lock set (1) and the component (100) to be assembled to : the gear lever or the gear arm (33). 25° Figure 1 illustrates the longitudinal profile of the lock of this invention, : having a pin (2) located ina slot (3) ona casing (6). The lock (1) consists of a lock cylinder (4) incorporated with a tumbler (5). The lock is installed in the casing (6). A cylinder-shaped end or plunger (7) of the lock cylinder (4) protrudes from a hole (8) located at the tail end of the casing (6). While locating the lock cylinder (4) to the casing (6), the pin (2), whichis a grub-screw, is screwed to the lock cylinder (4) through the slot (3). A spring (9) is loaded between the rear part of the lock cylinder (4) and the inner end of the casing (6).

Figure 2 illustrates the longitudinal profile of the lock of this invention, - displaying a cam (10) fitted inside the plug of the lock cylinder (4) behind the tumbler (5). A spring (11) is loaded between the hole drilled into the cam and the lock cylinder (4). In the locked position, the cam will obstruct the locking bolt inside ahole (1 2) located on casing (6). A detent (13) is made on the cam (10) for abutting a ledge (14) of the tumbler (5), to unlock the device.

Figure 3 illustrates the component to be assembled to the gear lever or the gear arm (33), which is comprised of a fastener (20) for the gear lever or gear arm (33). The fastener is separated into two (2) parts (21 and 22). Each part has a concave dent (23 and 24) on their opposing sides, for attachment to the gear lever or gear arm (35). A platform (25) is located on one part of the fastener (21 or 22), containing a hole (26) to allow the insertion of the cylinder-shaped end (7) of the lock cylinder (4), which is pressed into the locking position. © Figure 4 illustrates the flange of this invention which is fitted to the gear arm.

The lock (1) is installed on a structure (30) located around the transmission mechanism of the gear. The gear lever or gear arm fastener (20) is fitted to the gear arm (33) in such a manner that forces the gear into a position that enables the cylinder-shaped end (7) to be inserted into the hole (26), while the lock is pressed into the locking position. :

Figure 5 illustrates the flange of this invention installed with the gear lever (33). The lock (1) is installed on a structure (30) located around the transmission mechanism of the gear. The gear lever or gear arm fastener. (20) is fitted to the gear lever (33) in such manner that forces the gear into a position that enables the cylinder-shaped end (7) to be inserted into the hole (26), while the lock is pressed into the locking position. - 30 The invention will be understood to embrace many further modifications as will be readily apparent to persons skilled in the art and which will be deemed to reside within the broad scope and ambit of the invention, there having been set forth herein only the broad nature of the invention and a specific embodiment by way of example.

Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.

Claims

JI The claims defining the invention are as follows: :
