• the curved shape can be obtained by folding the blade with an angle preferably close to 90 ° along a line parallel to its longitudinal axis.
• the top of the folding angle will have a sufficient radius of curvature to avoid breaking the blade during folding; in fact, in the preferred case where the metal used is blued steel sheet, it would break on bending if the angle at the top was too sharp.
• This technique is used to reduce manufacturing costs, which would be generated by the use of a metal which should be quenched after folding to increase the hardness.
• the blade can adopt all kinds of forms suitable for increasing its rigidity.
• This shape may be partially or entirely circular, or possibly wavy. So that this blade, despite its folding described above, withstands the forces resulting from the impacts of the hammer used to drive it into the wall, it will preferably be guided by the part that it serves to fix on the wall or by a guide tool.

• the maximum mechanical resistance to shearing can be obtained both by the shape of the blade and by the fact that this shape will be reflected both in the fixing piece and in the wall; the rigidity obtained by the shape of the blade, and by the guide of the blade inside the fixing piece on the wall, will facilitate the penetration of said blade into the wall when it is pushed in with blows hammers. Folding the blade at an angle will allow it to be guided by its top; similarly, if the blade has a wavy shape, it will also be guided and stiffened. This will make it possible to offer blades of different dimensions depending on the weight to be supported.
• the blade will not have to penetrate much into the wall to ensure high shear strength. This resistance will be ensured by the anchoring surface in the wall, generated by the shape of the blade.
• a blade having a width of approximately 10 mm (deployed) and penetrating into the wall 4 mm deep makes it possible to obtain an anchoring surface of 40 mm 2 , which is important and makes it possible to support a significant weight.

• Figures 17 to 20 illustrate a preferred embodiment of an object support device such as a table and its implementation for fixing the object to the vertical wall 1; with reference to these figures in particular, the screw 20, 21 is provided at its lower end with a head 49 comprising an imprint 48, for example with a hexagon socket, for its drive by a screwdriver 38 provided with a flexible and long rod 39 terminated at one end by the handle 40, and terminated at its second end by a head 390 provided, on the one hand with a blade 41 of shape complementary to the imprint 48 provided in the head 49 of the screw, and provided by elsewhere, flexible and / or elastic jaws 42, 43 or fingers (for example made of plastic), which extend from said head 390 and which are provided in the vicinity of their free end and on an internal part thereof.
• a head 49 comprising an imprint 48, for example with a hexagon socket
• a screwdriver 38 provided with a flexible and long rod 39 terminated at one end by the handle 40, and terminated at its second end by a head 390 provided, on
• ramp 74 facilitates (during a movement of movement of the head 390 of the tool relative to the head 49 of the screw) the spacing of the branches 42, 43, so that these can slide around the head 49 until they tighten above the head 49, the diameter of which is greater than the diameter of the central part 50, to grip the head of the screw and allow the tool to be held in the position suspended from the head by its said fingers or jaws;
• the ramps 75 facilitate the spacing of the jaws and the separation of the tool from the screw 20, 21 during a pulling along arrow 381 on the handle 40 of the screwdriver 38.
• the block 6, 7 or body forming an intermediate support of the table has a preferred form of cylinder of rectangular section with axis 600 inclined with respect to the bases constituting the rear faces 57 and front 56 parallel to each other of the block; the block has four through holes 10 whose axes are parallel to the axis 600 of the block and has two slots 14 and 15 allowing the sliding of two blades such as those illustrated in FIGS. 12A and 12B, for fixing the block to the wall 1 Said block 6, 7 is thus limited by an upper wall 72 and a lower wall.
• the side walls 603 and 604 are flared and delimit two prominent parts 64 in the shape of an ear extending along an axis parallel to the axis 52 of the screw 20, 21; as illustrated in FIGS. 18 and 20.
• the adapter block 66 the surface of the rear face 68 of which is notably larger than the surface of the front and rear faces (57 and 56) of the block 6, can be fixed to the wall by said rear face 68 provided with a adhesive, as well as by fixing accessories such as nails extending through holes 661 provided in the adapter 66; said adapter is flattened and has a front face 67 parallel to the rear face 68 for fixing the adapter to the wall; the adapter can thus support block 6.
• the device according to the invention is used to suspend an object which has on its rear face 690 a recess or cavity 692 inside which the block 6, 7 and the screw 20 can extend , 21 for support and adjustment; in the case of a switchboard 69, this recess 692 results from the presence of the crosspieces 5, 401 of the frame, which are prominent with respect to said rear face 690, of a value which must be at least slightly greater than the distance between the axis 52 of the screws 20 and 21 and the extension of the front face 56 of the parts 6 and 7, for example at least equal to the thickness (reference 79 in figure 20) of the block, which is preferably of the order of 10 to 20 mm.
• the tool for positioning and helping to fix a flat object such as a painting against a wall by fixing means such as screw nails or blades comprises a first elongated bar 81 along a longitudinal axis 82, and a second bar 91 elongated along a longitudinal axis 83 perpendicular to said axis 82, and mounted to slide along its longitudinal axis 83 relative to said first bar, and having graduations 92 for measuring distance;
• the first bar includes:
• first cavities 86 for example regularly spaced along the bar, capable of receiving at least part of a intermediate fixing element 6, 7 of the switchboard, and of a thickness or depth 99 such that said body 6, 7 can be housed at least in part in said first cavity with its rear face substantially flush with the rear face 88 of the first bar ;
• the first cavity 86 opens onto a front face 87 of the first bar by an orifice 98 allowing free passage and sliding of said fixing means 12, 13, 16, 17, 19 of the body, for their impacting in said wall.
• the bar 81 comprises several second cavities 85 able to receive a positioning and support element 8. 9 of the table which is screwed into said element 6, 7 intermediate fixing; the second cavity communicates with said first cavity and preferably extends along a longitudinal axis 84 perpendicular to said axis longitudinal 82 of the first bar, which second cavity 85 opens onto a lower face 90 as well as onto an upper face 89 of said first bar.
• the bar 81 elongated along its axis 82 (which is horizontal in the position of use) comprises only through cylindrical cavities 85, of vertical axis and of section matching the section of a head 49 of an adjustment screw; the upper face 89 of the bar is inclined so that the body 6, 7 resting by its lower face 71 on the face 89, has its rear face 57 pressed against the wall when the rear face 88 of the bar is also pressed against this wall.
• the tools illustrated in FIGS. 10, 21 and 22 facilitate the maintenance of the devices by the user during the driving in of the nails or blades, and also facilitate the positioning of the supports at the desired locations for attachment to the wall.
