Abstract

The subject of the present invention is a trampoline-type training apparatus. According to the invention, this apparatus consists of a reinforced-resin grid 1, each of the lateral edges of which is mounted on a support 4-5 so as both to pivot about a transverse axis and to move longitudinally.

Description

La présente invention a pour objet un appareil d'entrainement, du genre tremplin, qui peut entre utilisé notamment pour l'entrainement à la course à pied, au ski de descente ou à la danse rythmique, comme tremplin de saut ou pour faire travailler les muscles des jambes et du dos. The subject of the present invention is a training device, of the springboard type, which can in particular be used for training in running, downhill skiing or rhythmic dance, as a jump springboard or for working out the leg and back muscles.

Cet appareilest caracteriseen ce qu'il est constitué par un caillebotis en résine armée, dont chacun des bords latéraux est monté sur un support de façon à pouvoir à la fois pivoter autour d'un axe transversal et se déplacer longitudinalement. This device is characterized in that it consists of a reinforced resin grating, each of the lateral edges of which is mounted on a support so that it can both pivot around a transverse axis and move longitudinally.

Le caillebotis présente à la fois une grande résistance mécanique et une excellente souplesse. The grating has both high mechanical strength and excellent flexibility.

Si l'on saute de maniere réguliere sur le caillebotis, celui-ci prend une flèche, ce qui lui est possible grace à la nature du matériau de ce caillebotis et à la liaison mobile de ses bords latéraux par rapport aux supports, et accompagne les sauts en se déformant de manière alternée par rapport à son plan. L'énergie emmagasinée par le caillebotis lors d'un saut est restituée immédiatement après. If we jump in a regular way on the grating, it takes an arrow, which is possible thanks to the nature of the material of this grating and the movable connection of its lateral edges with respect to the supports, and accompanies the jumps by deforming alternately with respect to its plane. The energy stored by the grating during a jump is returned immediately after.

On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation de l'appareil selon l'invention, avec référence aux dessins annexés dans lesquels
La Figure 1 en est une vue en plan;
La Figure 2 en est une élévation latérale;
La Figure 3 est une vue en coupe d'un détail suivant

An embodiment of the apparatus according to the invention has been described below, by way of non-limiting example, with reference to the appended drawings in which
Figure 1 is a plan view;
Figure 2 is a side elevation;
Figure 3 is a sectional view of a following detail
III-III of Figure 1;
Figure 4 is a sectional view of a following detail
IV-IV of Figure 3.

Tel qu'il est représenté au dessin, l'appareil d'entraînement selon l'invention comprend un caillebotis en résine synthétique armée de fibres de verre, qui est désigné au dessin d'une façon générale par la référence 1. Ce caillebotis est constitué de plats 2 qui sont disposés verticalement, parallèlement les uns aux autres, et sont reliés par des tiges 3. Celles-ci traversent des trous prévus dans les plats et sont collées à ces derniers. As shown in the drawing, the drive apparatus according to the invention comprises a grating made of synthetic resin reinforced with glass fibers, which is generally designated in the drawing by the reference 1. This grating is constituted dishes 2 which are arranged vertically, parallel to each other, and are connected by rods 3. These pass through holes provided in the dishes and are glued to the latter.

Chacun des bords latéraux du caillebotis 1 est relié à deux berceaux 4 ancrés au sol par l'intermédiaire de platines 4a, cette fixation étant assurée d'une manière à la fois articulée autour d'un axe transversal et permettant un certain déplacement du bord correspondant vers l'intérieur du caillebotis. Each of the lateral edges of the grating 1 is connected to two cradles 4 anchored to the ground by means of plates 4a, this fixing being provided in a manner both articulated around a transverse axis and allowing a certain displacement of the corresponding edge towards the inside of the grating.

Les deux berceaux sont réunis l'un à l'autre par un profilé en U 5 dont chacune des extrémités est fermée par une plaque 6. Cette plaque est percée d'une ouverture oblongue 7 dirigée dans la direction longitudinale du caillebotis 1 et dans laquelle est engagée la cage extérieure d'un roulement à billes 8. Un axe 9 a ses extrémités montées à rotation par rapport aux plaques 6, par l'intermédiaire des roulements 8, et empechées de se dégager de ces roulements par des rondelles 10 et des vis 11. The two cradles are joined to each other by a U-shaped profile 5, each of the ends of which is closed by a plate 6. This plate is pierced with an oblong opening 7 directed in the longitudinal direction of the grating 1 and in which is engaged the outer cage of a ball bearing 8. An axis 9 has its ends rotatably mounted relative to the plates 6, by means of the bearings 8, and prevented from being released from these bearings by washers 10 and screw 11.

Un plat 12 est soudé sur l'axe 9. Des étriers ou cavaliers 13, dont la partie inférieure est munie d'une ouverture verticale 14, sont engagés sur l'une des tiges d'extrémité a du caillebotis et fixé par des vis 15 sur le plat 12, avec interposition a'une plaquette de caoutchouc 16.  A plate 12 is welded to the axis 9. Stirrups or jumpers 13, the lower part of which is provided with a vertical opening 14, are engaged on one of the end rods a of the grating and fixed by screws 15 on the flat 12, with interposition to a rubber plate 16.

La disposition est telle qu'au repos, c'est-a-dire quand le caillebotis est pratiquement plan, les deux axes 9 se trouvent, par rapport aux berceaux 4, dans leurs positions les plus éloignées du centre du caillebotis, les rouleaux 8 étant en butée contre les fonds des ouvertures oblongues 7. Le caillebotis ne peut ainsi se déplacer longitudinalement par rapport aux berceaux. The arrangement is such that at rest, that is to say when the grating is practically flat, the two axes 9 are, relative to the cradles 4, in their positions furthest from the center of the grating, the rollers 8 being in abutment against the bottoms of the oblong openings 7. The grating cannot thus move longitudinally relative to the cradles.

Lors de l'utilisation de l'appareil, par exemple lorsqu'on saute sur le caillebotis, celui-ci peut prendre une certaine flèche. En effet, chacune de ses extrémités latérales est solidaire de l'un des axes 9; mais celui-ci peut pivoter autour de son axe par rapport au bâti dixie, et en mdme temps se rapprocher du centre du caillebotis, les rouleaux 8 coulissant dans les ouvertures 7. Lorsque l'appareil cesse d'etre utilisé, le caillebotis reprend sa forme plane. When using the device, for example when jumping on the grating, it can take a certain arrow. Indeed, each of its lateral ends is integral with one of the axes 9; but the latter can pivot around its axis with respect to the tenth frame, and at the same time approach the center of the grating, the rollers 8 sliding in the openings 7. When the apparatus ceases to be used, the grating resumes its flat shape.

I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et représenté, mais en couvre au contraire toutes les variantes. C'est ainsi notamment que le caillebotis 1 pourrait être recouvert d'un tapis souple.  I1 goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants. Thus in particular that the grating 1 could be covered with a flexible mat.
