Abstract

Improved closing device, namely one that rotates the inner cylinder with the turning of the key and this in turn turns other cam-like parts to lock or unlock the anti-theft mechanism, which is characterized in that the bulb (2) in its end contacting the cam has a plurality of lugs (1) displaced towards the outer sides with respect to an imaginary central axis (5) resulting from the prolongation of the opening enabled for the insertion of the key, so that of the plurality of lugs, the use of 2 being optimal, none of them is positioned on said imaginary central axis (5), it being foreseen that on the opposite or internal face of the cam (3) or (6), there are two housings positioned likewise to that of the lugs of the bulb in order to achieve a coupling of the bulb with the cam (3) or (6), so that on said central axis (5) the male function (7) of the coupling performs the cam (3) or (6), and the female function is carried out by the bulb (2).

Description

Improved closing device.

Technical field

Accessories that prevent unauthorized use or theft of two or four wheel vehicles.

Anti-theft for two or four vehicles wheels.

Background of the invention

There are devices, within the field of technique, in which the male female coupling of the lock light bulb with the cam that locks or unlocks the rest of the closing mechanism, is made by coupling a protruding pin existing in the center of one end of the bulb, with a cavity or central housing of the cam, said cam cavity remaining centered on a central axis resulting from the prolongation of the hole enabled for key insertion, so that on said central axis the male function of the coupling is performed the bumper of the light bulb and the female function of the coupling lo Make the cam.

By entering the key in the light bulb is rotated the bulb with the protruding stud, which at its this time transmits the turn to the cam, which locks or unlocks the rest of the locking mechanism of an anti-theft lock. This common system, is vulnerable to attacks, in case central part, a screwdriver sharp instrument, can access the cavity or housing of the cam, breaking through the brute force inside the bulb, and thus rotate the cam directly without the use of its corresponding key.

Therefore there is no lock with the differentiating features that we will discuss below and that thanks to them you get more security and adaptability.

Description of the invention

The device of the invention has a new structure based on which the connection of the light bulb lock with the cam that locks or unlocks the rest of the anti-theft mechanism, is carried out very effectively, and attack resistance of screwdriver sharp instruments. To do this, the male female coupling of the light bulb lock with the cam has the peculiarity that, on the central axis resulting from the extension of the hole enabled for introduction of the key, the face coinciding with the bulb of the cam, does not present any cavity or housing, so that exactly on said central axis the male function of the coupling is performed by the cam and the female function is performed by the light bulb, which allows, although it can be traversed by brute force inside the bulb, introducing an instrument stabbing through the key-enabled hole, said instrument cannot stay directly on cam and turn the.

Optionally you can place a disk protector inside the bulb, at the end of the hole key introduction and parallel under the lugs of Connection.

To complement the description, which then it will be carried out in the preferred embodiment, and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive of a set of planes, based on whose figures are they will more easily understand the innovations and advantages of device object of the invention.

Description of a preferred embodiment

In view of the figures, it can be seen as The device consists of a light bulb lock (2) coupled to a cam (3) or (6), where the bulb (2) at its end that contact the cam, it has two lugs (1) and where the cam (3) or (6) on the opposite or internal face has two accommodations enabled to couple the lugs (1) of the bulb, remaining, both the lugs (1) and the cam housings (3) or (6), displaced towards the outer sides with respect to a central axis (5) resulting from the extension of the hole enabled for key introduction. Said lugs (1) are introduced in two housings that have the cam (3) or (6) positioned of the same way as the said lugs, so by insertion and rotation of the key, turn the bulb (2) with the lugs and at the same time the cam (3) or (6). With that we get the inner face of the cam (3) or (6) not present no housing centered on the central axis (5) resulting from the extension of the hole enabled for the introduction of the key, so that on said central axis (5) the function male (7) of the coupling is made by cam (3) and the Female function is performed by the bulb (2).

Optionally, the device can be reinforce, housing a protective disk (4) inside the bulb (2) at the end of the key insertion hole and in parallel under the connection studs. This protective disk (4) can have several geometries like square, circular, hexagonal, being its optimum circular shape, and this may have an extension to the cam contact area (3).

Claims (3)

1. Improved closing device, specifically one that turns the inner bulb with the turn of the key and this in turn rotates other cam-type parts to lock or unlock the anti-theft mechanism, characterized in that the bulb (2) in its end that contacts the cam, has a plurality of lugs (1) displaced towards the outer sides with respect to an imaginary central axis (5) resulting from the extension of the hole enabled for the introduction of the key, so that of the plurality of lugs, the optimum being the use of 2, none of them is positioned on said imaginary central axis (5), it being provided that on the opposite or internal face of the cam (3) or (6), there are two positioned housings of in the same way as the lugs of the bulb in order to achieve a coupling of the bulb with the cam (3) or (6), so that on said central axis (5) the male function (7) of the coupling is performed by the to cam (3) or (6), and the female function is performed by the bulb (2). 2. Improved closing device according to claim 1, characterized in that the bulb houses a protective disk (4) in its central part, parallel under the lugs (1). This (4) can have several geometries such as square, circular, hexagonal, its optimum shape being circular. 3. Improved closing device according to claim 2, characterized in that its protective disk can have an extension to the face of the cam (3) that confronts the light bulb (2).
