Definitions
- the invention relates to a legrest device for a seat and an armchair in particular and, in particular, a retractable legrest device under the seat or armchair and which has in service a large length and thickness of cushion ensuring complete and comfortable support. people’s legs.
- a leg rest device for seat or armchair characterized in that it comprises a set of two cushions, substantially the width of the leg rest, which retract one below on the other under the seat or armchair in the out-of-service position and which extend forward in continuity with each other and with the seat element of the seat or armchair in the service position, each of the planes cushions corresponding respectively in vertical cross section to the front side and to the lower side of a triangle articulated at its vertices, the upper vertex being articulated to the front part of the seat or armchair and its rear side being connected to a means of translation integral with the seat or armchair, the lowest cushion plane (on the lower side of the triangle) being slidably mounted longitudinally on its front articulation.
- the rear side of the triangle is constituted by a link joining the rear articulation of the lower cushion plane and the support articulation of the triangle, this link being connected to said means of translation secured to the seat frame, this means of translation by pushing the articulated triangle creating a general movement of rotation of the articulated triangle which flattens at first thanks to the sliding of its front articulation, and then rotates forward in a flat service arrangement where the cushions are continuously one on the other and in an angular orientation adjustable as desired under the control of said translation means, and vice versa by traction.
- leg rest arrangement with an articulated triangle, suspended from the front part of the seat or armchair equipped with a possibility of transverse sliding of the lower cushion relative to the second cushion close to the seat until bringing it in continuity of plane relative to the latter, at an angular orientation of small angle relative to the vertical, then a possibility of rotation of the legrest, of the two cushions simultaneously, at a variable and adjustable angle according to the position desired by the supported person.
- the legrest according to the invention comprises two parallel lateral fittings in the form of a plate on each side of the seat element supporting the support plane of the upper cushion, two parallel slide elements connected to the support plane of the lower cushion, the two lateral fittings being mounted articulated to the front part of the seat or armchair at their upper end, and connected to each of the slides at their lower end, and at least one connecting rod connected to said slides and to said fittings and forming the rear side of the articulated triangle.
- the link can be connected by its upper end to an upper tab secured to the support plane of the upper cushion.
- FIGS. 1 and 2 are schematic views of a legrest device according to the invention without cushions, respectively in cross section in the retracted retracted position and in perspective in service extension
- FIGS. 3 to 6 are schematic views showing the various stages of the putting into service of this legrest device.
- the legrest device according to the invention comprises a set of two parallel lateral fittings 1, articulated at their upper end to the part .-. nt of the seat element 3 of the fitted seat or armchair * . h and a set of parallel lateral slides 7, each adjacent to a fitting, and mounted articulated and sliding at the lower end of the fittings.
- the fittings are arranged on either side of the seat element 3 of the chair, each being articulated in a vertical lateral plane of the chair.
- the plane of articulation and sliding of the slides is the same as that of the fittings, namely vertical and in the extension of each of the fittings.
- the fittings are identical to each other and consist of a plate of substantially triangular shape and the apex A of the triangle at the rear is under the seat element 3 or seat cushion of the seat or the armchair .
- These fittings are rigidly connected to a transverse plate 9 supporting a first cushion 11 or upper cushion of the legrest ( Figures 3-6).
- This plate is rectangular, substantially the width of the cushion it receives. It is mounted with the plate embedded in it.
- the slides 7 are also connected to a plate 13 supporting a second cushion 15 or lower cushion mounted adjacent to the first.
- This plate is also rectangular, of the same width as the associated cushion and the latter is mounted with the plate embedded therein.
- the width of the two cushions in the longitudinal plane of the seat or chair) is substantially equal to the half-length of the legrest in use ( Figures 5 and 6).
- a rear connecting rod 17 connects the set of slides 7 to the set of fittings 1.
- This connecting rod is articulated at the rear part of the set of slides, in its median plane and at the level of the apex part A of the set of fittings also in its plane median.
- This connecting rod is therefore in movement in a vertical median plane of the seat or chair, being hinged to a rear lower tab 19 secured to the plate 13 of the set of slides and to an upper tab 21 secured to the plate 9 of the set of fittings.
- the kinematic assembly constituted is therefore analogous to a triangle articulated in section, mounted suspended from the front part of the seat element 3.
- a rear rod 23 disposed under the seat element is articulated connected to the link 17. This rod is driven in translation, pushing or pulling according to arrow, by a motor element, such as a screw jack, mounted integral with the seat or frame of the chair.
- FIG. 3 the legrest is in the retracted position under the seat or chair, folded back into the free space under the element of seat 3 and between the side uprights, not shown, of the frame or chassis of the seat or chair.
- the upper cushion 11 is arranged with its front face in a substantially vertical position.
- the lower cushion 15 is completely retracted back, its upper face touching the upper cushion and its front edge comes in the vertical extension of the front face of the upper cushion. It is a short distance from the ground.
- a first deployment phase FIG.
- the seat element of the seat or armchair can be mobile, according to a movement of small amplitude, of translation or of angular orientation, accompanying the movement of the legrest for optimal comfort of leg support.
- the kinematics described works perfectly.
- the legrest can also be mounted articulated by its fittings 1 to the lateral uprights of the support frame of the seat or armchair, for example to its lateral armrest elements.
- the cushions can be of relatively large thickness, without the kinematics of articulated triangle being prevented. This ensures good comfort in supporting the legs (without pressure point).
- the cushion 11 can be connected to a rear spring secured to the frame of the seat or chair and recalling it in the vertical orientation.
- This spring while retaining the cushion promotes the sliding of the cushion 15 to prevent the assembly of the two cushions from being lifted as a whole without prior sliding of the lower cushion and likewise the return to the retracted position of the cushions while ensuring a positive action on the sliding cushion lower than the lower limit of service orientation.
- the front end of the lower sliding cushion can be provided with a buffer intended to come in contact with the ground to favor the sliding of this cushion during this movement and vice versa when it returns to the retracted position.
