- the uprights are telescopic with adjustment means with simultaneous action.
- the adjustment means may include screw and nut mechanisms for the respective uprights and a bevel gear shaft, this shaft extending under the plate to simultaneously activate the mechanisms.
- the base preferably includes a mechanism for locking the inclined position of the tray relative to each of the uprights using a shaft extending from one upright to the other for simultaneous locking of the two lateral sides of the tray. .
- the tray has a metallic upper surface and the table includes writing or drawing accessories magnetized so as to allow them to adhere to the surface of the tray even when the latter is in an inclined or even vertical position.
- the tray has two armrests, modular and removable projecting on each side of the front edge of the tray, defining a recess for the housing adaptable to the body of
- the table includes support of arches on each side of the plate, these extending vertically to allow, by depression, the coupling of said arches with the bases, while allowing the rotation of the arches around 'a vertical axis. It is useful for the base to be mounted on rolling means on the ground, allowing the table to be moved.
- FIG. 1 is a perspective view of a work table for disabled people according to a preferred embodiment of the invention.
- FIG. 1 is a partial sectional view of an upright of the table of Figure 1.
- the table includes a tray 10 mounted on a base comprising two uprights 12 and 14 interconnected by a cross 16, these uprights and cross together forming a gantry.
- the uprights 12 and 14 are telescopic and respectively comprise upper parts 18 and 20, and lower parts 22 and 24 sliding inside the upper parts 18, 20 in order to allow the height of the tray 10 to be adjusted.
- lower 22, 24 are mounted on bases 26, 28 which extend transversely to the plate 10 in order to maintain the stability of the table.
- Swivel casters 30, 32, 34 and 36 are mounted on the ends of the bases 26 and 28 in order to allow the table to be moved by rolling on the ground. Brakes are provided on the casters 30 to 36 for foot actuation.
- Sleeves 38, 40, 42 and 44 are mounted vertically on the bases 26 and 28 in front of and behind the uprights 12 and 14. These sleeves 38 to 44, formed of sections of welded tubes, serve as support for the coupling, by sliding , suspension poles 46, 48 with the bases 26, 28, in different orientations, with the possibility of rotation of the poles around a vertical axis.
- the transverse sides of the plate 10 extend beyond the uprights 12, 14 and the bases 26, 28 in order to present a maximum working surface.
- the suspension arches 46 and 48 include lower parts 50 and 52 and upper parts 54 and 56 staggered relative to the corresponding parts 50 and 52, so that the arches are released from the lateral sides of the plate 10.
- arms 58 and 60 which extend above the plate 10.
- the length of the arms 58, 60 is sufficient so that the free ends of the arms are close to each other, at - above the middle of the tray as well parallel than diagonal position, as shown in Figure 1.
- a sleeve (not shown) allows the ends of the two arms to be joined by sliding and locking screws make it possible to secure it with said arms, thus reinforcing the support
- the hoops 46 and 48 can support different support objects or accessories. As shown in FIG. 1, the arch 46 carries a strap 62 linked to a sleeve 64 which slides on the arm 58 and is immobilized by a locking screw 66.
- the strap 62 forms a bracelet made up of two detachable parts in order to allow the passage of the user's arm and comprises a fastener which can be easily closed or opened, of the loop and hook type, (known under the brand VELCRO), for example.
- the strap 62 therefore makes it possible to support the user's arm while allowing it to move in the horizontal plane by virtue of the rotation of the lower part 50 in its respective sheath 38.
- FIG. 1 represents the hoop 48 supporting a lectern or a turns page 68 suspended from a sleeve 70 which slides on the arm 60, with immobilization by locking screw 72.
- the lectern 68 allows a document to be placed in a good reading position while leaving the surface of the tray 10 clear for the movement of user's arm.
- a storage unit in the form of an open rack, mounted on a stand, can be provided by sliding this stand into one of the empty sheaths, such as the sheath 40 of FIG. 1, for example.
- Armrests 74 and 76 are mounted in lateral projection on the front of the tray 10 and define between them, with the front edge of the tray 10, a recess 78 which receives the body of the user while its elbows come to rest on the armrests 74 and 76.
- armrests 74 and 76 can be modified according to the body size of the individual and at his request and are fixed to the tray 10 by slides 80 and 82 fixed under the tray 10. Locking screws (not shown) make it possible to lock the position of the armrests 74 and 76. If necessary, one or both armrests can be removed, without leaving any dangerous protrusion beyond the edge of the tray 10. The edges of the tray 10 and the armrests 74 and 76 are padded to better protect the user.
- the plate 10 is tiltable from the front vertical position to the rear vertical position. So that the accessories, (not shown), placed on the plate 10 do not slip, the upper surface of the plate 10 is coated with a sheet of lacquered sheet steel allowing the magnetic adhesion of the accessories, the undersides of which are magnetized. for this purpose.
- Accessories include a ruler, and object holders for example.
- FIG. 2 shows the mechanisms for adjusting the height and tilt of the plate 10.
- the mechanisms comprising similar parts for the respective uprights 12 and 14, only those of the part corresponding to the upright 14 are shown.
- each upright includes a screw and nut mechanism 100 mounted inside the upright.
- the two mechanisms 100 are connected together by a gear shaft 102, mounted inside the cross-member 16, under the plate 10.
- Each mechanism 100 comprises a screw comprising a bevel gear head 104, a barrel 106 and a rod with a trapezoidal thread 108.
- the screw is mounted vertically inside the upper part 20 of the upright 14 by a bushing 110 which keeps the screw in an upright position, the bearing being integral with the upper part 20 and carrying the weight of the plate 10 transmitted through the screw 20.
- the threaded rod 108 is screwed in a nut 112 which is integral with the lower part 24 of the upright 14.
- the nut 112 has a flange 114 which projects from the end of the lower part 24 in order to transmit the force, applied by the screw on the nut, to the lower part 24.
- the flange 114 slides in the upper part 20 to guide the end of the lower part 24.
- a ring 116 is mounted on the lower end of the upper part and has an opening in which slides the lower part 24 of the upright 14 in order to guide the end of the upper part 20 on the lower part 24.
- the parts 20 and 24 of the upright 14 as well as the nut 112 with its flange 114 and the ring 116 are all of rectangular section, which immobilizes the parts in rotation with respect to each other.
- the shaft 102 extends between the two uprights 12 and 14 under the plate 10 (not shown in Figure 2). It carries at each of its ends a bevel gear 118 which meshes with the toothing of the bevel gear 104, in order to urge it in rotation and to connect the two mechanisms with screws and nuts.
- the hexagon socket head 120 is accessible through an orifice 122, formed in the upper part 20 of the upright, by a crank (not shown) making it possible to manually rotate the shaft 102 and thus to adjust simultaneously, the height of the uprights 12 and 14.
- the plate 10 (not shown in Figure 2) is mounted on a spider 124 which is in turn mounted on the upright 14 for pivoting about an axis formed by a screw and nut assembly 126, the upright 12 comprising a similar device.
- the axes 126 allow the rotation of the cross-member 24 and therefore the inclination of the plate 10 around a parallel axis and above the cross-member 16.
- a shaft 130 extends inside the crosspiece 16 between the two uprights 12 and 14 and passes through a notch (not shown) in the segment 128, in the form of an arc of a circle, centered on the axis 126
- a plate 132 slides on the axis 126 and has a part provided with a female thread into which is screwed a section of the shaft 130 provided with a male thread.
- the end of the shaft 130 has a support collar 134 for the segment 128 and a head 136, with a hexagon socket, accessible using the crank used to turn the axis 102 through an opening 138 made in the upper part 20 of the uprights 12 and 14.
- the plate 132 presses the segment 128 against the flange 134, blocking the tilting movement of the plate 10.
- the axis 130 can then be turned in the other direction to release the tilt of the platform.
- the use of the table described is as follows. The user can be seated in a wheelchair or on a hospital bed, for example, and in either case either the wheelchair is approached the stationary table, or the table is slid over bed. In both cases, the portico shape of the base allows it to step over the furniture.
- the recess 78 allows the body of the user to be housed between the two armrests 74 and 76, which are then in the correct position to promote the support of the elbows.
- the strap 62 makes it possible to better control the movement of an arm of the user above the plate 10 by supporting it.
- the fact that it is in two parts makes it easier to insert and release the arm relative to the strap.
- the height adjustment of the table can be done by the crank with a multiplied movement, the two sides being adjusted at the same time, which facilitates the task and avoids any mechanical jamming due to asymmetrical movements.
- This crank can be replaced by a motor which comes under environmental control.
- crank, or motor allows you to lock or unlock the tilt of the table.
- This configuration greatly facilitates the support of the disabled person's body in the working position, without having to bend over the table and while allowing the provision of additional supports, or the positioning of accessories. of work or documents.
