Definitions

• the invention relates to leg rests, in particular for armchairs and in particular a leg rest 5 mounted sliding at the front of a chair and allowing a person to sit in it by its front face.
• a first well-known type consists of a hinged plate system at the front of the armchair, folded vertically into the out-of-service position and which is oriented in a cantilevered fashion forward to support the legs of the people at a desired angle.
• the plate has only a limited width, slightly greater than the thickness of the seat cushion, so that the legs of the seated persons are supported in compression over a small area and therefore the comfort of support is reduced.
• the legrest consists of a cushion, mounted on longitudinal slides at the front of the chair, which disappear under the seat of the chair in the out-of-service position and which are moved forward in service.
• access to the seat of the chair is impossible from the front and it requires swivel chair armrests or the like.
• the invention aims to remedy these drawbacks and proposes a leg rest device, intended in particular for an armchair, characterized in that it is slidably mounted laterally at the front of the armchair. 30 Thanks to this arrangement, the legrest cushion retracts laterally by simple push or pull, which allows people to access the armchair thus equipped by its front face as in a normal armchair. As soon as the person has installed himself in his chair, he brings the cushion back, for example using a leg, to the normal operating position, adjacent to the seat of the chair.
• the lateral sliding movement of the legs can be performed on a variable amplitude, depending on the width of the chair and in general equal to 1/2 the whole thereof, to allow easy access to the chair.
• t - The legrest can be mounted on a U-shaped support bracket, of width substantially equal to that of the seat cushion, placed in front of it and at a short distance and whose arms are connected to the frame of the chair. These arms can be 0 arranged laterally each between the seat cushion and the corresponding armrest of the chair, detachably connected and not visible to a variable orientation mechanism of the fitting and therefore of the leg rest cushion.
• the legrest consists of a cushion of dimensions suitable for supporting the legs, comprising a rigid flat cradle embedded in it, this cradle comprising a device for lateral sliding of a plate -support laterally attached to said fitting.
• the invention also relates to an armchair equipped with a leg rest device.
• FIG. 1 is a top view in section of a leg rest device according to the invention.
• FIG. 2 is a partial axial sectional view of this device showing in particular its connection to the chair.
• the legrest according to the invention designated by 1 mounted on a chair 3, essentially consists of a cushion 5 of substantially rectangular format in extension of the seat 7 of the chair, mounted integrally to a support fitting 9 disposed at the front of the chair.
• the leg rest cushion 5 has a width equivalent to the width of the seat cushion 7 of the chair, as well as its thickness. Its length is greater than that of the seat cushion. It includes within it a flat cradle 11 embedded in the thickness of the cushion and of width slightly less than the latter.
• This cradle houses a support plate 13 fixed by its external end to the fitting 9.
• This plate is arranged laterally on the fitting, on the right or on the left, on request, depending on the preferred direction of access, respectively on the left or right at the front of the chair.
• the plate is slidably mounted laterally inside the cradle, over the width of the latter, by means of two slides 15 formed parallel to the width side of the cushion, respectively at its front part and at its rear part.
• the slides consist of two conventional slide pieces 15a integral with the cradle cooperating with guide pieces 15b fixed on the width of the cradle. Note that only one front slide can still be used. - -
• the fitting has a U-shape whose straight main branch 17 has a width slightly greater than that of the seat cushion and whose opposite branches 19 are each arranged over a short length along one side of the seat cushion and the corresponding armrest (not shown) of the chair.
• the connection of the fitting to the orientation mechanism of the legrest is completely hidden between the seat cushion and the armrests.
• the drive can be carried out on one side only by means of a geared motor (not shown), the other articulation remaining free.
• the mounting of the leg rest in solidarity with the chair is therefore very easy by bringing the tabs of the fitting in coincidence with the corresponding receiving pads of the drive mechanism 25 of the chair.
• the main branch 17 of the fitting can be an element forming safety in bending, capable of bending to an excessive force on the legrest, this to protect the other elements from breaking.
• This branch can be easily changed by dismantling and reassembly on the opposite branches 19 or support arms of this fitting.
• the amplitude of the lateral translation of the legrest depends on the width of the support plate 13.
• the latter is arranged substantially on a lateral portion of the fitting, to the left or to the right, over 1/3 of its length , allows an amplitude of translation of the legrest substantially equal to 2/3 of the width of the seat, largely sufficient to allow access to the chair by its front face.
• the legrest can slide directly on the main branch of the fitting, for example by means of a telescopic rod guided on the main branch, which allows translation over the total width of the seat cushion.
• the main branch being rectilinear can also serve as a slide, being guided on an adequate grooving of the front part of the cradle of the leg rest cushion.
• the main branch 17 can be slidably mounted directly on the cradle, being detached from the branches or support arms 19.
• the ends of the arms and of the slide (the main branch) then include coupling hooks allowing the adaptation (of preferably in quick setting) of the cushion on the support arms.
• the arms in the out-of-service position, the arms can be folded down between the seat cushion and the armrest, thus concealing any mechanical part of the cushion assembly.
