Spare Tire Security Device

Abstract

A security device to safeguard spare tires with a rim is mounted on the underside of a vehicle with a cable attached to a pin on one end and a winch on the other end. The security device includes a flat disc base and a tube with several openings or holes. This device enters through the main spare tire rim opening, the base is supported on one side and the tube crosses it up to exit on the opposite side, thus protecting the cable that holds the tire. The cable and pin are introduced through the rim and they are introduced by the tube in such a way that the pin is inserted in a series of lateral holes in said tube. The cable and tire are adjusted by means of a winch. The cable that holds the tire is covered by the tube of the security device.

2. A spare tire security device according to claim 1, wherein a variable distance from the base is 0.05 cm to 5.0 cm.

3. A spare tire security device according to claim 1, wherein the tube can have any geometric profile so long as its length covers the length of the cables that support the spare tire.

4. A spare tire security device according to claim 1, wherein the tube length is smaller or equal than the spare tire width.

5. A spare tire security device according to claim 1, wherein the tube side openings can be of any shape as long as the pin can be introduced easily on both.

6. A spare tire security device according to claim 1, wherein the base includes a center opening that allows for extra cable to go through and a second tube of the same diameter than the tube is attached to the underside of the base by one of its ends, working as an extension of the tube and protecting the end of the wire cable spare length.

DETAILED DESCRIPTION OF THE INVENTION

[0029] This descriptive report describes a theft prevention spare tire security device primarily suited for underside mounting systems with a wire cable winch on one end and a pin on the other end.

[0030] The security device is comprised of two parts: a base (1) and a tube (2) perpendicularly and concentrically attached to the base at one end, where the tube longitudinal axis coincides at the base center.

[0031] The base (1) is comprised by a flat plate whose size is larger than the rim center holes; and the tube's (2) dimensions are adequate so when the device is inserted through the rim of the spare tire, said tube can only be inserted but not the base

[0032] The tube (2) is hollow and works as a container and protector of the cable and it has to be installed in such a way that allows it to be inserted through the rim; it can be of any geometric profile as long as it covers the length of the cable and can be installed as previously described. The tube (2) has perforations on its lateral walls to form at least two lateral holes (3), where the pin (5) of the mounting device normally installed in the vehicle will be inserted.

[0033] Said mounting device has at least one cable (6) and a pin (5) attached to said cable, where both elements are incorporated to a winch mechanism to hold the spare tire in place. The tube diameter should allow the pin and cable to be easily inserted and for the pin itself to be placed through both lateral holes (3). Thus, if the cable hangs underneath the car, the security device stays in place by means of the pin (FIG. 5).

[0034] To install the security device, the spare tire is supported from the mounting device by introducing the cable and pin through the rim (7) of the spare tire (8) until the cable itself goes through the rim. The pin and the cable are then introduced through the upper tube opening (4) and the pin is placed through both side openings (3) with each one of the ends (FIG. 5). Then, the security device is placed concentrically on one of the rim sides, and its tube (2) is inserted through said rim until the base (1) meets the rim while the tube (2) goes through it (FIG. 6).

[0035] This way, once the spare tire (7) is mounted with the winch mechanism, there is no access to the cable (6) which holds it since is guarded by the tube (2) of the security device; this makes it impossible to remove the spare tire by severing the wire cable. This requires the use of heavier tools and more time in order to disable or destroy the security device.

Preferred Embodiments of the Invention

[0036] In a preferred embodiment of this invention, the base diameter can change depending on the diameter of the rim orifices; for example, the rim of a truck tire requires a base size bigger than the rim of a compact vehicle.

[0037] In another embodiment, the number and size of the side openings (3) can change to match the shape and size of the pin of the vehicle security system.

[0038] In another embodiment, the openings are situated from 0.5 cm to 5.0 cm to the base, in order to cover the cable from cutting tools when attempting to reach it by deflating the rubber tire and moving it upwards. Said cable is covered by the tube (2) hampering attempts to cut the cable.

[0039] In another embodiment, to facilitate manufacturing and operation, the tube (2) is recommended to have a cylindrical profile.

[0040] In another embodiment, the security device's materials should be made of a metal that facilitates soldering, while being tough enough to cover and protect the wire cable from being severed.

[0041] In another embodiment, the length of the tube (2) should be equal or smaller than the tire width in order to completely cover the access to the wire cable (6) that holds the spare tire (8) to the vehicle; such that the wire cable is covered by the security device on the case that the tire is deflated hampering attempts to cut the cable.

[0042] In another embodiment, the base has a center opening allowing spare cable through and a tube of the same diameter than the main tube (2) is joined to the underside of the base, working as an extension of the main tube and protecting the end of the wire cable extra length (6).

Invention Advantages and Innovation

[0043] The invention presented on this descriptive report is a security device for spare tires mounted on a vehicle, and its design and characteristics present several benefits to the user. Through analysis of the Detailed Description, the Preferred Embodiments of the Invention and the presented Figures, the following advantages can be discerned. [0044] The device has a simple design comprised of two components: a base (1) and a tube (2) [0045] According to the embodiment of invention where the tube is cylindrical, the design is tougher, and the material used in its manufacture is minimized. [0046] Since the security device is designed as a single piece and the pin can only be inserted in one specific way, which results on an easy installation process. [0047] The toughness of the tube provides enough protection to make it a difficult process to sever the wire cable that mounts the tire to the vehicle. [0048] The device itself is an accessory, adjustable to different vehicle types with different spare tire mounting methods.
