FR2762196A1 - Foot rest with adjustable inclination and height - Google Patents

Abstract

The pouffe (M) is put against a fixed seat (SF) and one side of its upper plate is raised or lowered to adjust its inclination. It is moved by an electric motor whose ends pivot on the frame of the pouffe. The pouffe is raised or lowered by adjustable height plates that support its rollers or the rollers can be fixed to different height legs. A case can be put on the pouffe to raise it or to form a low table.

Description

 The present invention relates to a device for tilting the seat plate of an independent pouf above and below its horizontal portion.

Adjusting the height of the feet makes it possible to put it against all types of fixed seats and to transform it safely into a leg rest with wheels.

 The footrest is traditionally incorporated in the seat. Its position is determined automatically according to the inclination of the backrest and the seat.

For the most advanced automatic models this positioning is independent by tilting one or two narrow foam strips. When he has one, it is just under the feet. This part is connected to the seat by a strip of fabric. These models are without any protection system when in use.

 The device of the invention overcomes all these disadvantages by fitting against the seat an independent module on wheels that moves at the right distance to the seat to allow the legs not to be compressed to the knees in any high or low tilt position of the seat pan relative to the horizontal.

 This module looks much like a beanbag with wheels on the outside.

Instead of being square it is rectangular to allow to rest on the foam feet and especially all the legs of even the largest people.

 The feet of this module are adjustable vertically and manually to fit all seat heights. By reversing the direction of use it can be immediately attached to the higher seat of a chair for the elderly or disabled.

 The seat plate is primarily electrically adjustable but it can be also pneumatically or manually in all positions inclined above and below its horizontal poof position. These indinaisons are obtained from one of the short sides of fixed height of the mobile on which is at its top a joint connecting it to one of the sides of the seat plate. The other side is of variable height and corresponds to the other end of the seat. The slow displacement of the electrical solution allows a precise adjustment to find its optimum comfort as well in relaxed or relaxed position.

 Below the high relaxed position, the closure fabric that is no longer tight returns inside by tensioners hung under the mounting system.

Alternatively there is a fan closure system on both lengths and accordion width.

The module is fully removable for quick change or cleaning.

The safety is particularly studied in electric mode: * with a low-voltage motor 12 Volts * with a special connection at the input of the module to connect the power wire
one just when using eê with alternatively a built-in battery for wireless use. The
refills are done at night.

* with a security system that blocks the descent as soon as there is an obstacle:
foot, hand, etc. between the moving part and the low fixed part of the module.

Alternatively, there is provided a low power electric motor. This module can only be used as a leg rest. We can hide it and use it in pouf by coming to the head of a bottomless box. The horizontal part covered with foam serves as a pouf and withstands a heavy load. The two small sides are provided with shelves that by folding on the foam turns it into a coffee table.

 The accompanying drawings illustrate the invention. Figure 1 shows in perspective the outside of the rectangular module (L '> L> I) and H on wheels (R) which horizontally is in poof mode.

 FIGS. 2 show in the different positions of the legs the displacement (D) of the module (M) relative to the fixed seat (SF) so that the legs (J) are at the same place on the module whatever the desired position: low (JB) or horizontal (JH) or relax (JR).

 Figures 3 allow to see the height adjustment of the module to adapt to all heights (H1 and H2) fixed seat (SF). These are either right-angled (MD) amounts for the upper part or folded amounts (MR) for the lower part. The amounts are positioned inside the structure. It can be an independent plateau with feet of different heights (P1-P2).

 Figure 4 shows the uses of the module (M) according to the direction: low for fixed seats (SF), high for chair (C).

 Figure 5 shows the electric motor that pivots at both ends (P 1) and (P2) on the frame of the module and under the inclined seat plate (I). The articulation (A) and the seat plate are protected by suitable foams (MS) to their specific needs.

 Figure 6 shows the tissues that are stretched inwards under the engine as soon as you are no longer in the high relax position (T1) for the width and (T2) for the two lengths at an angle.

 Figure 7 shows the location of the self-adhesive strips (B) on the module structure as well as the electrical plug (P) to be plugged for use or overnight charging.

 Figure 8 shows the safety with the bar (S) which disengages the descent by sliding the point (P2) of the motor (M) on the bar when meeting an obstade (O).

 Figure 9 shows the leg rest (RJ) on which is placed the fixed pouf (PF) with the two hanging shelves (T).

 Figure 10 shows the fixed pouf (PF) which can be transformed into a coffee table (TB) by folding the two hanging tablets on the foam.

 The realization can be made with wooden cleats for the structure and the sinter for the two triangular struts as well as the fixed vertical part. This set can be made with a three-sided molded structure made of hard recyclable plastic. The inclined plate may be of chipboard or plywood 3 or 5 plies. The extensions are preferably wood because of the visible parts but can be as well painted metal or plastic to give futuristic forms. The connection between the indined part and the rest is achieved by several hinges or a piano hinge. The whole is covered with mosses of different densities and soft according to the places. The whole is dressed by fabric, skai or leather according to the desired aesthetic. The operation is ensured by a B.T. electric motor or a pneumatic cylinder or manually with a rack system.
