FR2747576A1 - Stilt with platform having gyratory movement - Google Patents

Abstract

The stilt has a platform (5) for the feet on an upper tube (4) that is joined to an intermediate tube. This slides in a lower tube that rests on the ground. A cable (15) is fixed to the lower tube and to the intermediate tube. The cable is attached to the tubes by a fixed point (11,14) and by rotating parts (12,13) that allow the platform to rotate. A spring (1) is mounted round the intermediate tube, just under the upper tube, and is compressed between the tubes.

Description

The present invention relates to a shock absorption device, and to widening the possibilities of movement when practicing changes on stilts.

 The different types of current stilts offer more restricted possibilities of movements and approaches due to their characteristic of fixed, integral construction, of the axis carrying the stilt, in contact with the ground, relative to the base of the stilt properly said. In addition and taking into account this construction characteristic, the foot platform, an integral part of the base, where the user is placed, does not receive any modification, from its distance from the ground, hence the absence of 'a compression effect of the construction, which could be intended to absorb shocks, due to use when walking, or performing different movements.

 These shocks can cause trauma; especially in the lumbar region of the spine.

 The device according to the invention overcomes this drawback, while providing a more flexible approach, as well as a wider range of movements. I1 comprises, according to a first characteristic, a spring and a pivot device at 3600, arising from the mounting of the spring to the stilt.

The user after placing his foot on the platform provided for this purpose, strap it, (the straps are not shown in the drawings), then proceeds to fix his leg, on the tube forming the upper part of stilt, thanks to a clamping member.

 He does the same in order to put on the second stilt.

During its movements, its weight makes it possible to compress the spring, which has the effect of varying the distance of the foot platform from the ground, hence the principle of shock absorption.

The principle of free mounting of the base, relative to the tube resting on the ground, allows the user, when he wishes, to make gyratory movements.

According to the particular embodiments: - The stilt can be composed of a base, comprising the foot platform and different integral elements which compose it.

- To these elements can be added the upper part, and its clamping member.

- This part can be assembled to the base by sliding and fixed by bolting.

- A tube can in turn be added to the base.

- This tube can be assembled to the base by sliding and fixed by bolting.

- This tube can extend the base and serve as an axis.

- This axis thus formed can enter by sliding into a second tube bearing on the ground.

 - This axis as well as the integral and added parts of the base, can have vertical and gyratory mobility, relative to this second tube, bearing on the ground.

The axle and its extension tube can be connected to each other using a cable.

 - This cable can be fitted at its ends with two gyratory hanging devices.

 - Cable twisting can thus be avoided.

 - A mobile spring can be placed between, the tube resting on the ground, and the base of the stilt.

 - This movable spring can be crossed and held by the tube extending the base.

 - This spring can be compressed in order to absorb shocks and allow movements such as: Bounces, Bounces, Jumps.

 - The compression of the spring can be variable, depending on the characteristics of the spring used, as well as the types of movements made by the user.

 - In view of the different physical capacities for each individual, a variable adaptation period may be necessary in order to make full use of the operating possibilities of the devices.

The accompanying drawings illustrate the invention:
Figure 1 shows in section, the device of the invention.

 Figure 2 shows the device from the side.

 Figure 3 shows the device from the front.

 With reference to these drawings, the device comprises, a base made up of integral elements such as: A foot platform (5), two plates (9) and (10), two reinforcements (7) and (8) , two sections of tube (4) and (16), and added elements such as: A top part (6), sliding in the part (16), and provided with its clamping member (17).

 A tube (2), sliding in the part (4), extending the latter and thus serving as an axis for the base of the stilt, and for holding the spring (1).

 A second tube (3), receiving the tube (2), by sliding.

 A spring (1), placed between the parts (3) and (4).

 A cable (15), and two gyratory hanging devices (12) and (13).

 A threaded rod (11), used to fix the parts (6), and (2) to the base; and serving as a point of attachment to the device (12).

 A second threaded rod (14), serving as a point of attachment to the device (13).

 A clamping member (17).

 Two reinforcements (19) and (20) of the tube (3).

 A non-slip cap (21).

 By way of example, the base made up of the parts, (5), (16), (4), (7), (8), (9), (10), can be produced in one piece by plastic molding or aluminum.

 By way of nonlimiting example, stilts can have different heights.

The device according to the invention is particularly intended for damping shocks and widening the range of movements during movements on stilts.
