Description

The present invention relates to an antitheft device and more particularly to an antitheft device for motorcycle helmet, bicycle helmet or the like. However, the device according to the invention will find many other applications such as a safe (bag) car safety for example.

Wearing the helmet is mandatory for motorcyclists in particular and said helmet is particularly bulky and provides discomfort when the motorcyclist leaves his vehicle. Indeed, almost all motorcycles do not have means for safely storing the helmet and many motorcyclists are thus content to fix their helmet to one of the wheels of the motorcycle with a padlock and / or of a chain. However, this solution has the disadvantage of causing staining, especially in case of bad weather, and / or scratches on the helmets so that many motorcyclists prefer to take their helmet despite the inconvenience caused by the clutter said helmets.

To remedy these drawbacks, it has already imagined motorcycle boxes, also called "top case" which are attached to the rear loop of the motorcycle frame and have a volume adapted to receive a motorcycle helmet. Such a motorcycle trunk is described in Japanese Patent JPS 5757172, in the international patent application WO 02/34613 and in the European patent application EP 2316717 in particular.

However, this type of storage means has the disadvantage of not being able to be attached to all types of motorcycle including, in particular, so-called sports bikes whose frame does not include a rear loop adapted to receive such a motorcycle trunk. In addition, this type of storage means does not have an aesthetic adapted to that of these sports bikes.

To overcome this disadvantage, we have already imagined anti-theft devices for motorcycle helmet that do not require a motorcycle trunk. This is particularly the case of the French patent application FR 2 547 263.

Document FR 2 547 263 describes an anti-theft device for a motorcyclist's protective helmet, ensuring the retention of the helmet on the saddle of the motorcycle. Said device is constituted by a simple wire ring, of smaller diameter than the largest lower diameter of the helmet, held in place by two main tensioning wires, connected to the ring by two diametrically opposed points and by two connected secondary tensioning lines. to the ring by two points, located on a diameter perpendicular to the diameter connecting the main points, the ends of the secondary ropes being connected to each of the main ropes in the vicinity of their ends, and the ends of the main ropes being connected to means of hooking located at the lower part of the saddle, on each of the lateral sides.

This type of device has the disadvantage of being bulky when it is not used. Indeed, when the motorcyclist wears his helmet, he must hold the ring and the ropes, the motorcycles do not have adequate storage means to contain them.

Flexible anti-theft devices are also known which are easier to store, in a pocket for example, when they are not used. This is particularly the case for patent applications WO 92/19116 and WO 2011/135143 in particular.

WO 92/19116 describes a protection against theft and against the weather for the helmets of users of two-wheelers. Said protection consists of a bag of water-repellent material which has an opening for introducing the helmet. To obtain in a simple way a great security, one of the ends of a chain or rope located inside the bag is connected to the bag, and opposite the introduction opening is arranged an eyelet for the passage of a fixing lug fixed to the other end of the rope or chain, said lug being connectable to a closure element consisting of a cable provided with a padlock.

This type of device has the disadvantage of offering only a very limited security insofar as the bag has a low resistance and where the cable can be cut very easily by means of a simple cutting plier.

WO 2011/135143 discloses a cover formed by a net consisting of longitudinal and transverse son, to wrap the helmet, which is connected to an interlaced steel cable which is at the base thereof; presenting at its two ends, which remain on each side of the helmet, one of the parts of an anchoring system being intended to secure the cover with the helmet to the motorcycle, all the net being introduced into an envelope. The thread or screening of threads being of iron or steel, and the envelope of textile material. Said net can be folded and, when not used to protect the helmet, can remain anchored to the bike and attached to it.

This type of device makes it possible to secure the helmet only on the seat or the central tank of the motorcycle. In addition, the cost of manufacturing the net is expensive, thus affecting the cost of manufacturing the assembly. The invention aims to overcome the disadvantages of the state of the art by providing an invention providing an anti-theft device for motorcycle helmet or the like in particular, simple and inexpensive design, having a very small footprint when n ' is not used, providing protection against bad weather and ensuring good resistance in case of attempted theft. For this purpose and in accordance with the invention, there is provided an antitheft device of objects or values comprising at least one envelope obtained in an impervious textile having a resistance to perforation of level 4 and a tear resistance greater than or equal to at least 30 daN for the warp and weft threads, said envelope being provided with an opening closed by a slide fastener and at least two slots adapted to receive a flexible strap made of metal-reinforced polymer, said strap having at each of its free ends a loop adapted to receive a padlock.

It is understood that the envelope provides sufficient strength to prevent any attempt to unexpectedly open the envelope and that the strap can be cut by a simple pliers. In addition, the device can be easily folded, including the soft strap, and fit in the pocket of a jacket or coat when not in use.

In order to limit manufacturing costs, said loops are formed by the strap, the ends of the strap being then folded to be sewn onto the strap and thus form said loops.

In order to avoid any contamination of the contents of the envelope, said slide fastener is advantageously impermeable.

Preferably, the zipper comprises a shuttle provided with a zipper having an eyelet, said eyelet being adapted to receive a padlock. Note that the same padlock can also be used for closing the strap and fixing the device on any suitable support.

Preferably, the envelope is obtained in a polyester fabric.

Said polyester fabric has a basis weight of at least 450 g / m2.

Moreover, said polyester fabric has a thickness of between 1 and 2 mm.

Advantageously, the casing has a generally ovoid shape adapted to receive a motorcycle helmet or the like, comprising a flat bottom and a curvilinear zipper extending on one of the lateral sides of the casing for a long period of time. first end of the flat bottom to the opposite end of said flat bottom.

Furthermore, the slots are made in the flat bottom at one end of said flat bottom and the slots extend parallel and perpendicular to the sagittal plane of said envelope.
