ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention is related to the field of gliding sports, snowboarding in particular, and it is especially related to a device for retaining a boot on a glide board and, more particularly, on a snowboard.
2. Description of Background and Relevant Information
The sport of snowboarding is generally practiced with boots that are connected to a glide board via retention devices. When a user employs flexible boots that allow for easy walking, he has to use retention devices that enable rear support to be taken with the lower part of the leg, so that the board performs correctly.
Known retention devices generally comprise a base affixed to the board via a disk and screws. A rear support element whose position can be adjusted longitudinally with respect to the base allows the boot to be positioned on the device via heel contact, and attachment means retain the boot on the device in contact with the base and the rear support element.
These devices make the steering of the board possible, but they do have certain disadvantages. In particular, the adjustment of the position of the foot with respect to the board is time consuming and difficult to undertake, thus causing lost time. This problem is particularly vexing for businesses that rent out equipment, and who must quickly adjust a retention device according to the size of the boot. Another disadvantage is a lack of precision in the rear supports taken, due to the presence of a clearance between the boot and the rear support element.
SUMMARY OF THE INVENTION
An object of the invention is to resolve the problem of the time that it takes to adjust a retention device, as well as the problem of the clearance between the boot and the rear support element of the device.
In order to resolve these problems, the invention provides for a retention device for a boot on a glide board adapted for snowboarding, such device comprising a base, a plate, a disk and at least one retention screw for the disk provided to attach same to the board, the base having a rear support element provided to come into contact with the boot, a retention element affixed to the plate and enabling the boot to be retained on the device, the device extending along a longitudinal direction which is the longitudinal direction of the boot when the latter is retained on the device.
The device according to the invention includes at least one mechanism for the translational guidance of the plate with respect to the base along the longitudinal direction of the device. Consequently, the clearance between the boot and the rear support clement can be adjusted to a zero value so as to enable rear supports to be taken with precision.
Another specificity of the device is that the disk biases the plate and the base towards the board when the screw is screwed into the board, such that the plate and the base are immobilized simultaneously with respect to the board.
The retention screw or screws for the disk enable the device to be positioned on the board and the rear support clement to be kept in contact with the boot. An advantageous result thereof is that the time required for adjusting the device becomes very short when compared to a traditional device.
Preferably, the translational guide mechanism is obtained by the cooperation of at least one groove of the plate with at least one projecting ridge/lip of the base, the groove and the ridge being oriented parallel to the longitudinal direction of the device. Thus, it becomes possible to bring the rear support element closer to or further away from the boot with great ease.
The device according to the invention also comprises a positioning mechanism provided to translationally position the plate with respect to the base in the longitudinal direction.
Preferably, the positioning mechanism has a cursor that permanently biases the plate towards the base via a pinching effect.
Thus, it becomes possible to tighten the retention screws of the disk without any risk of upsetting the position of the base with respect to the plate. The presence of the positioning mechanism enables the position of the plate to be adjusted with respect to the base, before adjusting the position of the device on the board.
The disk preferably has a peripheral surface provided to position the plate with respect to the disk, the plate having a surface that is complementary to that of the disk.
Finally, according to a preferred embodiment of the invention, the retention element of the boot and the translational guide mechanism of the plate with respect to the base are arranged in the vicinity of a lateral edge of the device. This facilitates the putting on and removal of the boot.
The invention is also related to an assembly having a board and a retention device.
