Description

<Desc / Clms Page number 1>

The present invention relates to a chair and accessories allowing either an individual concerned with his physical condition to tone his main muscle groups 1 and to relax his back muscles by mechanical massage, or to professionals, physiotherapist, physical education teacher, trainer physical, graduate of the trades of the form, etc ..., to make execute under their control an education or a physical re-education to customers applicants.

 Benches and machines for bodybuilding or rehabilitation are traditionally bulky, heavy, equipped with complicated mechanical systems and therefore not transportable at home.

présenter dans un volume réduit qui la rend facilement transportable et rangeable. Son 1 attrait principal est d'en faire un objet ou un outil, d'un poids à la portée de tout à chacun, remisable au fond d'un placard de rangement ou dans un coffre d'automobile. The chair equipped with all its accessories has the advantage of being foldable and therefore of being

present in a reduced volume which makes it easily transportable and stowable. Its 1 main attraction is to make it an object or a tool, of a weight within the reach of everyone, put away at the bottom of a storage cupboard or in a car trunk.

Once unfolded, it can also be fixed to the ground to ensure its stability in certain environments.

Depending on the physical exercise to be performed, the chair seat is placed in an inclined or horizontal position using two support legs which are designed to allow them when folding the seat to place them behind the offset cross of the rear feet where clips are attached for storing certain parts. A sliding and pivoting handle locks the front and rear legs of the chair in the folded position, in the unfolded position the leg opening is locked by a pivoting safety device or a compass device. The various physical exercises are done using accessories which are elastic elements of traction of variable resistance according to their number, their diameter, their length and their material. Some elements are fitted at one end with a handle and at the other end with any quick-attach system, carabiner, fastening with self-gripping textile fiber tape. The anchor points of the elastics on the frame of the chair are multiple and repeated to allow a more adjusted adjustment of the elastics according to the type of exercise to be performed and the morphology of the practitioner.

 The accompanying drawings illustrate the invention.

1: 1
With reference to these drawings, the chair comprises a frame comprising 2 frames articulated together: - a component constituting the front legs (1) provided with a backrest (2) and the reclining and folding seat (3). The seat is wedged in an inclined position by an articulated leg (4) bearing on the lower spacer (5) of the front feet. Its position is ensured in a closed notch (6). In the horizontal position, the seat is wedged by another articulated leg (7) brought into the vertical position maintained and limited by stops included under the seat.

The 2 legs are independent and articulated on the same axis. The leg (4) is made of a single cleat. The leg (7) comprises two battens braced downwards. When folding the two legs, to fold the seat, the leg (4) is between the two elements of the leg (7).

 - The other constituting the rear legs (8) is consolidated by a deported cross (9) which is in fact the stabilizing element of the chair. The carrying handle (10) fixed freely on one of the rear legs can slide along an oblong hole receiving the pivot. The handle is engaged under a wing nut (11) as soon as the feet are one against the other. Tightening the nut confirms the locking of the folded feet.

The rear feet on their inside are fitted with clips (12) to secure certain parts.

A blocking security (13) ensures that the feet are kept open.

The four feet are provided with support plates (14) for fixing to the ground. The elastic elements (15) equipped with a handle (16) and with a carabiner (17) are fixed to the anchoring points (18) located at the bottom of the four legs and in the center of the spider.

. une tige (19) amovible s'adaptant dans des trous prépercés dans les pieds avant (1) . une tige (20) équipée en son milieu d'un manchon (21) souple semi-dur ou de propriété et de forme adaptées au massage. Elle sert également de poignée. The parts necessary for the back massage are:

. a removable rod (19) fitting into pre-drilled holes in the front legs (1). a rod (20) equipped in the middle with a flexible sleeve (21) semi-hard or of property and shape suitable for massage. It also serves as a handle.

. elastic elements (22) looped at their ends are simply slid by force on the two rods and positioned in notches.

Claims (1)

The thigh-leg frame is fixed in the pre-drilled holes at the front of the seat using the rod (19) which projects on either side of the seat to serve as a handle. An elastic element (23) connects the supporting leg (7) to the braced uprights (24) (25) which comprise at 1/3 of their length a damping roller (26) mounted on an axis (27) which can be placed in different positions in pre-drilled holes in the uprights. In order to relieve the transfer of forces to the upper stops of the support leg (7), an adjustable tie rod (28) is fixed between them and the front feet.  For transport, this frame is pressed against the seat of the folded chair and is held there using two existing elastic elements (15) intertwined.  For example, a fully equipped chair made of exotic hardwood has a minimum volume when folded of 1.10 m x 0.40 m x 0.16 m and weighs approximately 9 kg.  The fully equipped chair according to the invention enters the field of the rapidly expanding fitness market concomitant with the leisure market.
