- the present invention relates to a device for assisting inflation of an inflatable element. She finds in particular an application for the practice of water sports. It also finds an application for the practice of mountain activities and, more generally, for the practice of any outdoor activity that may require the use of tracking means. Those who adhere to such sports or outdoor activities in fact wish to have means of assistance or tracking, which can be operated when needed, and having a small footprint that does not interfere with their freedom of movement the rest of the time.
- This type of device which can take the form of a lifejacket or a buoy, generally requires to be inflated prior to the sporting activity; it generally comes, by its size when inflated, limit the freedom of movement of the user.
- a compressed air cartridge that the user perforates when necessary, to inflate the inflatable device.
- the user wears the deflated device in a pocket formed on his bathing suit. In case of difficulty, it perforates, by means of a push button, a cartridge of compressed air. The air thus released by the cartridge inflates the device, which is then a means to facilitate the user's flotation.
- Such a device nevertheless has the disadvantage of being able to be actuated accidentally, the kinematics of the push button favoring the inadvertent perforation of the compressed air cartridge.
- Such devices are usually disposable, the cartridge and the inflatable device being, for sealing constraints, fixed so that when inflated, the device inflatable must be replaced.
- Such devices therefore generally have a deterrent cost for their purchase and use.
- the present invention aims to overcome the drawbacks identified above, and to allow water sports enthusiasts to be equipped with a device for assisting inflation of an inflatable element, which can in particular be operated only in case of need and easily reusable.
- the invention relates to a device for assisting inflation of an inflatable element by means of a compressed air cartridge, comprising:

- the cam portion 62 of the actuating means 40 is not in contact with the outer face 38 of the wall 34 in the rest position P1. Nevertheless, an actuating means 40 could be conceived. which would be in contact with the wall 34 in the rest position PI without exerting any pressure on the wall 34, or possibly the existence of an intermediate piece between the actuating means 40 and the wall 34, without departing from the scope of the present invention.
- FIGS. 4A to 4E show schematically an example of use of an inflation aid 100 of an inflatable element 10 according to the invention.
- the inflatable element 10 is a buoyancy aid that a water sports enthusiast can use when needed.
- the user fixes the assembly constituted by the receptacle 20, the compressed air cartridge C and the protective cap 32 at his wrist.
- This attachment allows, among other things, the inflatable element 10, when inflated, to remain attached to the user.
- the user then wraps the inflatable element 10, then deflated, also around his wrist.
- a storage device such as for example a textile envelope, in which the inflatable element 10 deflated, after having been rolled on itself or simply folded, would be placed.
- the user can for example wind up the storage device containing the inflatable element 10 around his wrist or his ankle, so that he can operate it if necessary.
- the storage device containing the inflatable element 10 may also comprise fixing means, which may for example consist of a lace or a self-gripping band, allowing the storage device to be removably attached to the user, directly on a portion of his body, or through one of his clothes.
- the small size of the inflation aid device 100 according to the invention allows the user to practice his activity freely, without the device causes the slightest discomfort.
- the user may wish to have assistance with flotation. It then suffices for him, at first, to unroll the inflatable element 10 that he wears deflated and wrapped around the wrist, and, in a second step, and as shown in Figure 4D, to actuate the element gripping device 60 of the actuating means 40 to move it to the active position P2.
- the actuation of the gripping element 60 makes it possible to perforate the compressed air cartridge C, and thus to inflate the inflatable element 10.
- a storage of the inflatable element 10, when deflated such that the actuation of the actuating means 40 allows both to unroll and inflate the inflatable element 10.
- the user thus has an inflated inflatable element 10 by which its flotation is facilitated; he can thus regain strength or signal his position around him.
- the perforation means 28 could be formed on or near the inner face 36 of the wall 34, without departing from the scope of the present invention; it would then be sufficient for the fins 31 to be adapted to receive the end 16 of the compressed air cartridge C, the end 14 being able to be perforated then being disposed close to the insertion opening 26 of the receptacle 20 where the perforating means 28 would be located.
- the actuating means 40 could be constituted by a pin system, a hinge or any other means for applying to the cartridge of the invention.
- compressed air C a force F2 sufficient to release the gas G contained in the compressed air cartridge C.
- the invention although particularly suited to the field of devices for assisting flotation, could also be used to equip devices to be identified, such as a floating flag, or, in general, any equipment used in an outdoor activity requiring the use of an inflatable element.
