Abstract

The seat includes a flexible seat element (3) and a support structure for supporting and stretching out this seat element. This support structure includes legs (2) joined by a positioning component (1) including holes designed to allow the legs to assume a vertical position in the folded state and an inclined position in the unfolded state in which they provide stable support for the seat element. … …

Description

FOLDING SEAT

  The present invention relates to a seat and it relates, more particularly, to a seat whose structure is improved, which is stable and can be adjusted and which can be assembled and disassembled easily, A known folding seat 4, as shown in FIG. 1, comprises an actual seat or seat element 41 formed of a flexible material, such as canvas, and a support structure 43 for supporting and tensioning the seat element 41 The support structure 43 includes three rigid tubular feet 44 made of stainless steel or plastic and a positioning piece 45 to hold them together

  pivoting the feet 44 in their middle parts.

  The positioning piece 45 consists of a rigid plate comprising three holes distributed evenly in order to receive the feet 44 These holes act as a fulcrum for the feet 44 so that the ends of the feet 44 can deviate towards the outside so as to form a base with their lower ends in order to stably position the seat 4 All that is necessary to complete the assembly of the seat 4 is to slide the flexible seat element 41 towards the low between the upper parts of the feet 44 while releasably engaging loops or other retaining means

  suitable for the upper ends of the feet 44.

  This known seat has a drawback since, when someone is seated on the seat element 41 of the seat, the feet 44 tend to give way while moving apart, which makes the seat 4 unstable and quickly damages its aspect and its role To this end, the inventor attempted to produce an improved seat

  to overcome the disadvantages of the known seat.

  The subject of the present invention is a seat which

  can reduce the disadvantages of the known seat.

  The present invention also relates to a seat that can easily, quickly and easily assemble, adjust, disassemble and store in a minimum

  space and in minimum time without the use of tools.

  The preferred embodiment of the present invention will now be described by way of example with reference to the accompanying drawings, in which: FIG. 1 is a perspective view showing a known seat; Figure 2 is a perspective view showing a first preferred embodiment of the present invention; Figure 3 is a schematic perspective view showing a positioning part according to the present invention; Figure 4 is a schematic side elevational view of the first preferred embodiment shown in Figure 2; Figure 5 is a schematic side elevational view of the first embodiment in the folded state; Figure 6 is a top plan view of a second preferred embodiment according to the present invention; and Figure 7 is a perspective view showing another preferred embodiment of the present invention and wherein the seat member is integral

with a folder.

  Referring now to Figures 2, 3, 4 and 5, it can be seen that there is shown diagrammatically a first preferred embodiment of the improved seat of the present invention. Thus, this seat comprises an actual seat or element of flexible seat 3 formed of a canvas or other material of great longevity and a structure intended to support and tension the seat element 3 The support structure comprises four identical tubular legs 2 and a positioning part 1 now pivotally assembled feet 2 in

their middle parts.

  Positioning piece 1 is a solid hexahedron, preferably having a square horizontal cross section

  and in which four guide holes 11 are formed.

  The four guide holes 11 are divided into two pairs of opposite holes Each guide hole It extends vertically through the body of the positioning piece 1 and diverges up and down

  from a horizontal median plane of the body 1.

  The guide hole 11 has vertical interior side walls 112 and inclined interior side walls 111 and a leg 2 is fixed so

  pivotable in the guide hole 11 by means of a screw.

  The guide hole 11 thus produced allows the foot 2 pivotally fixed in this hole to pivot around the screw and along a vertical plane parallel to the vertical side wall adjacent to the guide hole 11 of the body 1 between a position vertical in which the foot 2 coincides with the vertical interior side walls 112 and an inclined position in which the foot 2 coincides with the inclined interior side walls 111 of the guide hole 11 Figure 5 shows the seat of the present invention with its feet 2 assembled in a vertical compact form, while

  the seat element 3 is folded into a compact position.

  The four feet 2 all pivot in the same direction of rotation, as for example in the direction of clockwise or anticlockwise, from their vertical position to their inclined position The ends of the feet can be moved outwards and their lower ends form a base for the stable positioning of the seat, their upper ends being ready to receive loops or other suitable retaining means which are engaged on these ends so as to complete the seat assembly or, as shown in Figure 6, to support a panel such as a table top 31 which has two halves assembled by hinges 32 and four stop brackets 33 mounted on the underside and in the four parts angles from above 31

of table.

  As can be seen in FIG. 7, in another embodiment two adjacent feet 2 are longer than the two remaining feet 2 so as to form a backrest in the seat element 3 when this

  element is completely open and stretched.

  The play of the assembly between the feet and the positioning piece 1 allows, when a person is seated on the seat element 3, a slight adjustment of the feet 2 so that (a) the middle parts of the latter rest tightly against the inclined inner side walls of the guide hole 111 of the positioning piece 1, (b) the stability of the seat increases, (c) the seat adjusts automatically for support

  appropriate to the weight of the user of this seat.

  It is understood that the foregoing description

  has been given purely by way of non-limiting illustration and that variants and modifications may be made thereto within the framework of the present invention.

Claims (2)

  1 seat comprising: a seat support structure comprising four identical tubular legs (2) forming together at one of their common ends a base support for said seat, a positioning piece (1) for holding the legs together in their middle parts , this part being formed by a solid body having a cross section of square shape and comprising four guide holes (11), each guide hole being diverging upwards and diverging downwards from the middle part of its length to form a passage allowing the feet to take a vertical position and an inclined position, means for pivotally fixing the feet in the guide holes to the middle parts of the feet, the feet being adapted to pivot from their vertical positions to their inclined positions; and a flexible seat element (3) assembled to said feet along the latter at a point remote from said base support, whereby said seat element is suspended between the feet above from the support base.   2 seat comprising a seat support structure comprising four identical tubular legs (2) forming together at one of their common ends a base support for said seat, a positioning piece (1) for holding the legs together in their middle parts, this part being formed by a solid body having a cross section of square shape and comprising four guide holes (11), each guide hole being diverging upwards and diverging downwards from the middle part of its length to form a passage allowing the feet to assume a vertical position and an inclined position, means for pivotally fixing the feet in the guide holes to the middle parts of the feet, the feet being adapted to pivot from their vertical positions to their inclined positions; and a panel (31), such as a table top is mounted on the seat support structure.
