Definitions
- the present invention relates to a seat composed of assemblable elements having lateral uprights, a seat and a backrest.
- the invention proposes to remedy this problem by minimizing the number of parts necessary to fix the seat when it is mounted.
- the invention more particularly aims to provide a seat whose final assembly is blocked only by a minimum of fixing means, such as screws and nuts. Most of the stability of the mounted seat is ensured by an interlocking of the various elements constituting the seat and the fixing means finally making it possible to ensure this interlocking.

- the seat comprises uprights 110, 110 'formed in a single piece, a seat 120, a backrest 130, and a corner system 150.
- the uprights 110, 110' each have an approximately horizontal slot 111 and 111 'constituting a first means of nesting and in which come to fit the lateral edges of the seat 120.
- the seat has a slot 122 near its rear edge in which the backrest comes to fit approximately perpendicular to the seat which constitutes a means fitting between the seat 120 and the backrest 130.
- a wedge 150 is introduced between the backrest 130 and the uprights 110, 110'. The inclined face of the corner 150 is supported against the rear face of the backrest 130.
- the corner 150 and the backrest 130 are linked to each other by fixing means, for example by screws 182, 183 or other equivalent means.
- the face opposite the inclined face of the wedge 150 bears against the uprights 110, 110 'and is linked to these by means of fixing means, for example by screws 180, 181, or by other equivalent means.
- the backrest 130 is thus made integral with the uprights 110, 110 ′ and the various sockets of the mounted seat are therefore blocked.
- the corner can be placed either below the seat 120, as shown in Figure 1, or above and fixed to the back 130 and the uprights 110, 110 'in the same way as that previously described.
- a first variant of the first embodiment of the seat is shown in Figures 2 to 6.
- the elements common to the first embodiment and this variant have been designated by the same references.
- the seat according to this variant essentially consists of symmetrical lateral uprights 110, 110 ′, of a seat 120, of a backrest 130, of a screw 140, of a corner 150 and of a rider 160.
- the uprights 110 , 110 ′ are in the form of cylinder portions joining edge to edge at the rear of the seat.
- These uprights 110, 110 ′ each comprise an interlocking means constituted by an approximately horizontal slot 111, 111 ′ inside which the lateral edges of the seat 120 fit together perpendicularly to the lateral uprights.
- the seat 120 has on its front edge two notches 121, 121 'which prevent any lateral movement of the seat, when it is fitted into the uprights.
- the seat has a slot 122 near its rear edge, a slot in which the backrest fits approximately perpendicular to the seat.
- a third fitting means is provided between the seat 120 and the corner 150. It consists of a horizontal groove 152 formed in the corner 150, into which the seat fits by the notch 123 on its rear edge .
- the backrest 130 has a hole 131 in its lower half, this hole 131 allowing the passage of the screw 140.
- the corner 150 also has a hole 151 crossing it from the inclined plane 153 to the side 154 opposite the inclined plane parallel to the third side 155
- the inclined plane 153 is intended to bear against the rear face of the backrest 130 and the side 154, opposite the inclined plane and perpendicular to the hole 151, is intended to bear against the inner side of the rear joint of the uprights 110 , 110 '.
- the seat finally comprises the rider 160 which comes to nest by its two wings 161, 161 'in slots 112, 112' of the lateral uprights, thus maintaining the joint of the uprights closed.
- the rider 160 is integral with a nut 162 placed between the wings 161, 161 'of the rider.
- Figure 6 shows in detail the shape of the ends of the approximately horizontal slot 111 'of the upright 110'.
- the front end of the slot 111 ' is perpendicular to the front edge of the seat 120 while the rear end is parallel to the rear edge of the seat.
- the ends of the slot 111 are in the same way, perpendicular to the front edge of the seat 120 for the front end and parallel to the rear edge of the seat 120 for the rear end.
- the assembly of the seat shown can be carried out as follows. First of all, the seat 120 is slid into one of the slots 111 or 111 'of one of the lateral uprights 110 or 110'. Then, the file 130 is introduced into the slot 122 of the seat. The corner is then slid between the joint of the lateral upright 110 or 110 ′ and the backrest 130, the horizontal groove 152 being matched with the notch 123 of the seat 120. The seat 120 is then introduced into the slot 111 or 111 'of the second lateral upright and the latter is folded down until it joins the other lateral upright at the rear. The corner 150, through the inclined plane 153 pushes the backrest 130 forward.
- the latter by means of its interlocking with the seat 120, also pushes it towards the front of the seat, so the notches 121, 121 'are engaged in the front of the slots 111, 111' of the uprights.
- the wings 161, 161 ′ of the jumper 160 are introduced into the slots 112, 112 ′ of the lateral uprights, preventing the rear of the latter from moving away from one another, and the jumper 160 is provided by the screw 140 which passes through the hole 131 of the backrest 130 and the hole 151 of the corner 150, the head of the screw pressing on the front face of the backrest 130.
- a vertical displacement of the backrest is then prevented by the screw 140 and the assembly , once the screw 140 and the nut 162 are locked, can no longer be disassembled.
- FIG. 7 A second variant of the first embodiment is shown in FIG. 7.
- This variant corresponds to an embodiment made of metal, for example aluminum.
- the elements common to the first embodiment and to this variant have been designated by the same references.
- the edges of the seat 120 and of the backrest 130 are folded in order to give them sufficient rigidity.
- the edges of the lateral uprights 110, 110 ' can also be folded for the same reason. It is also possible to form a rib in them instead of bending their edges.
- the corner 150 has a slot 152 into which the seat 120 fits and its rear folded edge.
- FIG. 8 A third variant of the first embodiment is shown in FIG. 8.
- This variant comprises in particular an upright 110 in one piece and made of metal, for example aluminum, folded to give it the shape of a truncated cylinder.
- the seat 120 and the folder 130 have folded edges 124, 125, respectively 132, 133. In place of these folds, it is possible to provide ribs in the surfaces to obtain the same effect.
- the first fitting means is constituted by slots 111, 111 'approximately horizontal in the upright 110 in which the seat is inserted.
- the seat 120 has a slot 122 intended to receive the folder 130 in interlocking.
- the third nesting means consists of an approximately vertical slot 156 in the upper part of the corner and which receives the folded edge 124 of the seat 120 in nesting.
- the entire seat is fixed by four screws 141, 142, 143 and 144, two screws (141 and 142) passing through corresponding holes 134, 135 of the backrest to be screwed into the holes 157, 157 ' of the corner, and two screws (143 and 144) passing through corresponding holes 113, 114 of the upright 110 and being screwed into the holes 158 and 158 'of the corner.
- Reinforcement means 170 is also shown in this figure. This means takes the form of a crossbar fixed at its two ends to the folded upright 110 to prevent its deformation. Instead of this bar, mechanical or weld attachment points between the seat and the upright can also be used.
- the mounting of the seat according to this variant is carried out in a similar manner to the others. First of all the seat is fitted into the upright, then the backrest is fitted into the seat and finally the corner is fitted with the seat and the screws are put in place and tightened. Furthermore, in this variant, a single screw passing through the backrest, the corner and the upright combined with a nut can also be used in place of the four screws shown in FIG. 7.
- the seat is balanced by the lower part of the backrest 230 and the lower part of the uprights 210, 210 'close to the rear joint.
- the first fitting means is constituted by the slots 211, 211 'in the uprights 210, 210'
- the second fitting means is constituted by a horizontal slot 232 in the backrest 230 and it is the seat 220 which is fitted into the backrest.
- a third interlocking means is produced by a rectangular cut 221 in the seat, a cut into which the upper part of a wedge 250 fits.
- the inclined plane 253 of the wedge 250 cooperates with a countersink 233 located in the back surface of the backrest.
- a jumper 260 which is integral with a nut 262, is also used to block the joint of the lateral uprights, by means of its wings 261, 261 '.
- the nut 262 is connected to a screw 240 also passing through the backrest 230 and the corner 250, through their respective holes 231, 251.
- This second embodiment includes the upright 210, the seat 220, 97/36520 1 1 PCMB97 / 00320
- the upright 210 is formed in a single piece, the corner 280 extends to the ground and the single screw of the second mode is replaced by four screws 241, 242, 243 and 244 including two of between them (242 and 243) fix the backrest on the inclined face of the corner, and the other two (241 and 244) fix the corner to the single upright.
- the use of these four screws makes it possible in particular to take up the bending stresses to which the lower part of the upright is subjected when a person is seated on the seat.
- This variant comprises, similarly to the second mode, a first interlocking means constituted by the slot 211 in the upright 210 and as a second interlocking means the slot 232 in the backrest 230.
- the seat according to this mode mainly consists of symmetrical lateral uprights 310, 310 ′, of a seat 320, of a backrest 330, a screw 340, a spine-shaped wedge system 350, a jumper 360, a support piece 341, a wedge 343 and two nuts 342 and 345.
- the uprights 310, 310 ' are in the form of cylinder portions joining edge to edge at the rear of the seat. They each comprise the first interlocking means consisting of an approximately horizontal rectangular cutout 311, 311 ′ (see FIG. 20) inside which the seat 320 fits approximately perpendicularly to the rear joint of the lateral uprights 310 , 310 '.
- One of the seat supports on the floor is the lower rear edge of the uprights.
- the backrest 330 has a first horizontal rectangular cutout 331 intended to be crossed by the seat 320 and which is larger than the section of the seat 320.
- the lower edge 333 of the backrest which extends towards the front is in contact with the ground and constitutes the other fulcrum of the seat.
- a third interlocking means is produced by a longitudinal rectangular cutout 321 in the rear of the seat 320, a cutout which is composed of a wide part and a narrow part in which the upper part of the vertebral column 350.
- a notch 322, 322 'vertical intended to fit with the vertical edge of the rectangular cutouts 311, 311' of the uprights 310, 310 '.
- the seat finally has on its underside a notch 323 perpendicular to the longitudinal axis in which a locking piece 341 will be inserted and a countersink 324 in the longitudinal direction.
- the vertebral column 350 extending almost to the ground, comprises on the bottom of its front edge, which marries the rear surface of the backrest 330, a horizontal half dovetail 351 which comes to fit in a second cut 332 of the backrest so that the backrest is secured to the spine 350 and its detachment from the spine 350 when a person sits on the seat is prevented.
- the vertebral column 350 also has, on the bottom of its vertical rear edge, another half dovetail 352 which comes to fit into a cutout 312, 312 'of the uprights 310, 310' joined which has the effect of making the spine 350 integral with the uprights 310, 310 '.
- the wedge system is shown in detail in FIGS. 17 to 19.
- This system is cut in the faces of the upper part of the vertebral column 350 and it comprises in particular two inclined planes which produce a double wedge effect preventing the tilting of the 'seated forward.
- the seat 320 which is cantilevered, will tend to rotate forward around its interlocking with the spine 350.
- the contact surface which is at the back of the spine upwards and that which is at the front of the spine downwards flares so as to create this double wedge effect during load the seat and prevent rotation.
- This flare is shown in detail in Figures 14 and 16.
- the contact surfaces of the seat are also cut in correspondence with the surfaces of the spine as shown in Figure 16. The intersection of these two inclined planes gives the inclined line L shown in Figure 18.
- the blocking means used in this embodiment are described more particularly with reference to Figures 17 and 18. These means consist essentially of a screw 340, a support piece 341, two nuts 342, 345, a shim 343, an internally threaded sleeve 344 and a jumper 360.
- the internally threaded sleeve is embedded inside the vertebral column 350, in the middle of the zone comprising the double corner, and it is arranged approximately horizontally. The blocking of the seat is ensured by these elements and it takes place in three phases.
- the first consists of blocking the interlocking of the seat 320 and the spine 350 by the screw 340, the support piece 341 inserted in the slot 323 of the seat 320 and the internally threaded bush 344 embedded in the column vertebral 350.
- the head of the screw bearing on the support piece 341 linked to the seat 320, the tightening of the screw 340 in the internally threaded socket 344 linked to the vertebral column 350 will maintain the interlocking of the seat and the spine.
- the second phase is then to press the backrest 330 against the spine 350 by screwing the first nut 342 and the shim 343, previously mounted on the screw 340, in the direction of the threaded sleeve 344.
- the section of the rectangular cutout 331 of the backrest 330 being larger than the section of the seat 320, the backrest can slide freely on the seat.
- the third phase is finally to maintain the uprights 310, 310 'fitted into the vertical slots 322, 322' of the seat 320 by joining them together by the rider 360, the wings 361, 362 of which fit into the slots 313, 313 'amounts 310, 310'.
- the jumper 360 is secured by the second nut 345 on the screw 340.
- the mounting of the seat can be carried out in the manner shown in FIG. 20.
- the seat 320 is introduced into the cutout 331 of the backrest 330, the spine 350 is then fitted into the seat 320 behind the backrest 330.
- the screw 340, the first nut 342, the support piece 341 and the shim 343 are put in place and tightened.
- the uprights 310, 310 ' are fitted with the seat 320 and with the spine 350, the wings of the rider 360 are inserted into the uprights 310, 310' and the rider 360 is secured on the screw 340 by the nut 345.
- FIGS. 21 to 24 A fourth embodiment of the invention is described with reference to FIGS. 21 to 24.
- This mode uses in particular two symmetrical lateral uprights 410, 410 ′, a seat 420, a backrest 430, a system of corners 450, 470 , a jumper 460, a screw 440 and a nut 441.
- the lateral edges of the backrest 430 and of the seat 420 are folded approximately at right angles. Instead of this fold, it is also possible to form a rib to obtain equivalent reinforcement.
- the uprights 410, 410 'each have an approximately horizontal slot 411, 411' starting from their vertical rear edge and two approximately vertical slots 412, 412 ', 413, 413' connected to the horizontal slots, the second vertical slots 413, 413 'extending the horizontal slots 411, 411 'and the first vertical slots 412, 412' being located between the rear edge of the uprights and the second vertical slots 413, 413 '.
- the horizontal slots 411, 411 'and the vertical slots 413, 413' receive the seat 420 and its folded edges 421, 422 in interlocking, as the first interlocking means, while the first vertical slots 412, 412 'receive the wings 461, 462 of the jumper 460.
- the lower edge of the rear part of the uprights 410, 410' rests on the ground constituting a seat support point.
- the backrest 430 has a vertical rectangular shape and curved forward, its vertical edges 431, 432 are folded about at right angles to the surface and the lower horizontal edge rests on the ground.
- the backrest 430 has a rectangular cutout 433 at approximately mid-height which is crossed by the seat 420 and which constitutes the second interlocking means.
- the corner system 450, 470 comprises two jumpers 450, 470 whose wings 451, 452, 471, 472 flare.
- the first jumper 450 has on its back an approximately horizontal slot 456, two vertical rectangular cutouts 454, 455 connected by the slot 456 and a hole 453 approximately in the middle of the back.
- the slot 456 is crossed by the seat plate 420 before the latter fits into the slots 411, 411 'of the uprights and the cutouts 454, 455 are large enough to allow the folded edges 421, 422 of the seat 420 and the wings of the rider 460.
- the back of the rider 450 can be curved to match the curve of the internal face of the uprights 410, 41C joined.
- the second jumper 470 has a hole 473 approximately in the middle of its back.
- the third fitting means is then produced by fitting the seat 420 with the first jumper 450, the second jumper 470 and the backrest 430, as shown in FIG. 22.
- the third jumper 460, for the joining of the lateral uprights 410, 410 ′ may have a curved central part corresponding to the curve of the external face of the joined lateral uprights and pierced with a hole 463 to allow the screw 440 to pass, and two wings 461, 462 which fit into the corresponding slots 412, 412 'of the uprights 410, 410'.
- the blocking of the assembly is carried out by the interlocking of the various elements and the tightening of the nut 441 on the screw 440.
- FIGS. 21 and 24 make it possible in particular to better understand how the blocking takes place.
- the seat 420 passes through the cutout 433 in the backrest 430, and fits into the slot 456 of the first jumper 450 and into the horizontal slot 411, 411 'of the uprights 410, 410'.
- the lateral parts of the cutout 433 are then wedged between the outside of the folded edges 421, 422 of the seat 420 and the wings 451, 452 of the rider 450. Because the seat has a trapezoidal shape, its longitudinal movement is limit.
- the jumper 460 maintains the uprights 410, 410 'joined and the lateral position of the part 450.
- the second jumper 470 whose wings are supported on the faces inside of the folded edges 421, 422 of the seat 420, a wedge effect occurs when the nut 441 is tightened on the screw 440, effect which pulls the seat 420 rearward via the second jumper 470 and drives the backrest 430 which is pressed inside the part 450.
- the mounting of this embodiment can be carried out as follows: the seat 420 is fitted with the backrest 430 and the first jumper 450. The uprights 410, 410 'and they are fitted on the rear of the seat 420. The third rider 460 and the second rider 470 are placed and the assembly is secured by means of the screw 440 and the nut 441.
