Abstract

A security system (1), comprising a chassis side member (2) with holes on sides, at least one mechanism (3) allowing lowering and raising the spare tire fastened to one side of the chassis side member (2), a tip (4) of the lug wrench for moving the mechanism (3) by passing through the other hole of the chassis side member (2) and a stud (5) for preventing the access of the tip (4) of the lug wrench to the mechanism (3) and when disassembled, moving the mechanism (3) by making the tip (4) of the lug wrench reach the mechanism (3), the stud being situated in the center of the chassis side member (2) and characterized by a special nut (6) placed in the tip of the stud (5), outside the chassis side member (2) and integral with the stud (5).

Description

Description A SECURITY SYSTEM

[I] Technical Field

[2] The present invention relates to a vehicle security system for securing a spare tire mounted on commercial vehicles.

[3] Background of the Invention

[4] Today spare tires are fixed below the vehicles by means of a spare tire hoist and when the tire needs changing, said spare tire is taken out of its socket by being moved by means of a key and lug wrench on the mechanism. However, the tire can be stolen. There are various developments in the art in order to overcome this problem.

[5] CA2075125 discloses locking of a spare tire placed on a bumper to the shaft, with a padlock. But the padlock can easily be broken and the spare tire can be stolen.

[6] WO9856643 describes a lock which is secured to an insert on a hoist placed on the rear bumper, and also unlocking it with a key. Upon unlocking the lock mechanism is accessible via lug wrench. However, the key is carried by the user and it poses a problem for the user if the key gets lost. And the security lock can be broken with any tool such as a sledgehammer. Thus the spare tire can be stolen.

[7] In the state of the art any security system enabling ergonomic usage of spare tire hoists on commercial vehicles and securing the spare tire is not known.

[8] Brief Description of the Invention

[9] The object of the invention is to provide a security system in which spare tire hoist can only be used by the owner of the vehicle and to secure the spare tire from being stolen.

[10] Detailed Description of the Invention

[I I] The security system according to the invention is illustrated in the accompanying drawings in which:

[12] Figure 1 is a schematic view of the security system according to the invention.

[13] Figure 2 is a perspective view of a special nut, a lug wrench and a stud, those of which are the components of the security system according to the invention. [14] The components of the security system according to the invention are each given reference numerals: [15] 1. Security system

[16] 2. Chassis side member

[17] 3. Mechanism

[18] 4. Tip

[19] 5. Stud

[20] 6. Special nut [21] 7. Bracket

[22] 8. Adaptor

[23] 9. Head

[24] The security system (1) mainly comprises a chassis side member (2) with two holes on opposite sides, a mechanism (3) for lowering the spare tire to the ground and raising it, said spare tire being fastened to one side of the chassis side member (2), a lug wrench tip (4) for moving the mechanism (3) by passing through the other hole of the chassis side member (2), a stud (5) placed in the center of the chassis side member (2), said stud preventing the tip (4) from reaching the mechanism (3) and, when disassembled, allowing the tip (4) reach the mechanism (3), thereby allowing the movement of the mechanism (3), and a special nut (6) placed in the tip of the stud (5) outside the chassis side member (2) and integral with the stud (5).

[25] The chassis is the main frame of vehicles. The chassis is protected via the stud (5) inside the chassis side member (2) and a bracket (7) fastened with a rivet to the special lock (6), which is situated outside the chassis side member and integral with said stud (5).

[26] Said stud (5) is fastened to the chassis by means of special nut. An adapter (8) outside the chassis side member (2) of the stud (5) and mounted on the special nut (6) that is integral with the stud (5) helps removing the stud (5) by moving the special nut (6) by means of the lug wrench head (9).

[27] Tip (4) of the lug wrench facilitates lowering the spare tire to the ground and raising it by moving the mechanism (3). The lug wrench head (9) complies with the adapter (8) and thus makes the stud (5) move downwards in cooperation with the special nut (6).

[28] The adapter (8) is situated in the special nut (6), which is integral with the stud (5) and outside the chassis side member (2), when the spare tire needs changing. The special nut (6) is opened by means of the lug wrench head (9) and the stud (5) is perpendicularly pulled downwards. Therefore any barrier between the mechanism (3) and the lug wrench is eliminated. Then the tip (4) of the lug wrench has an access to the mechanism (3) through the hole on the chassis side member (2). After the tip (4) of the lug wrench moves the mechanism (3) the spare tire is lowered to the ground.

[29] In general the security system (1) according to the invention may be used to prevent stealing of the spare tire from heavy/light vehicles, cargo trucks and/or jeeps.

[30] Within this main concept, it is possible to develop various embodiments of the security system (1) according to the invention and the invention cannot be limited to the examples herein and is actually as in the claims.

Claims

[1] A security system (1), comprising a chassis side member (2) with holes on sides, at least one mechanism (3) allowing lowering and raising the spare tire fastened to one side of the chassis side member (2), a tip (4) of the lug wrench for moving the mechanism (3) by passing through the other hole of the chassis side member (2) and a stud (5) for preventing the access of the tip (4) of the lug wrench to the mechanism (3) and when disassembled, moving the mechanism (3) by making the tip (4) of the lug wrench reach the mechanism (3), the stud being situated in the center of the chassis side member (2) and characterized by a special nut (6) placed in the tip of the stud (5), outside the chassis side member (2) and integral with the stud (5).
