Definitions

  • the present invention relates to an adjustable support device for wall- mounted furniture.
  • the 'base support' or 'wall bracket' support devices In addition to the pure hanging function, a term which will thus be used in the following to refer to a support condition in a wall-mounted condition, the 'base support' or 'wall bracket' support devices must also possess a mechanism for the precise adjustment of the position of the furniture in the front/rear and top/bottom directions, so as to ensure both flush mounting on the wall and horizontality and alignment between several pieces of furniture side by side. This therefore requires a robust and relatively complex structure of the device with its various adjustment kinematics, which necessarily increase the size thereof.
  • adjustable support devices have therefore been proposed in the art, which are intended to be at least partially recessed in the inner wall of the shoulders of the furniture.
  • the general aim of the present invention is to provide an adjustable furniture hanging device which can be recessed at least partially in the shoulder of a piece of furniture in order to have reduced space requirements within the furniture, but which at the same time does not require hollows of complex shape and construction.
  • an adjustable support device for hanging furniture on a wall comprising a shaped plate, provided with two coplanar wings, intended to constrain the device to the furniture, and an intermediate zone, recessed with respect to a fixing plane identified by the two coplanar wings and which is intended to be housed in a recess in a shoulder of the furniture, the body of a hooked hanging arm and a kinematic mechanism for adjusting the position of the arm with respect to the shaped plate being housed in the intermediate zone, the hooked hanging arm protruding from the shaped plate and ending with a hooked end which is intended to hook onto a support plate fixed to a wall on which the furniture is to be hung, characterised in that the hooked hanging arm has a hooked end which is offset with respect to the body of the arm in order to be arranged in a hooking plane which is spaced, in the opposite direction to the recess formed by the intermediate zone, from the fixing plane identified by said two coplanar wings.
  • -figure 1 represents a schematic and perspective front view of an adjustable support device for a piece of furniture, made according to the principles of the present invention
  • FIG. 1 -figure 2 represents a rear, schematic and in perspective view of the device of figure 1 ;
  • -figure 3 represents an upper schematic view of the device of figure 1
  • -figure 4 represents a front schematic view of the device of figure 1 ;
  • Figure 1 shows an adjustable hanging device for furniture made according to the invention and generically indicated with 10.
  • the device 10 comprises a shaped plate 11 , provided with two coplanar wings 12, 13, intended for fixing the device to the furniture, and an intermediate zone 14 which is recessed with respect to the plane for fixing the furniture identified by the two wings.
  • the intermediate recessed zone 14 houses the body of a hanging arm 15 which protrudes from plate 11 and ends with a hooked end 16.
  • the hooked end 16 is intended to engage on a coupling seat in a support bracket 21 fixed to the wall 22 to which the furniture 23 is to be hung.
  • the furniture is shown only schematically and partially with a side shoulder 24 thereof and a rear back 25 thereof.
  • the device In its position of use, the device is intended to be oriented as shown in figure 1 , i.e. , with the plate 11 arranged in a vertical plane so that the wings 12 and 13 are arranged one above and the other below the intermediate recessed zone 14, respectively, so that the arm 15 extends lying substantially horizontally to be directed towards the rear of the furniture and protrude through an opening 46 in the back 25.
  • Relative position terms such as 'vertical', 'horizontal', 'front', 'back', etc. used in the present description are to be understood here as referring to such a position of use of the device.
  • the intermediate recessed zone 14 also houses a kinematic mechanism 18 for adjusting the position of the arm 15.
  • the adjustment substantially occurs in a plane which is parallel to the plane identified by the two wings and which will be vertical when the device is in its condition of use on the furniture.
  • the kinematic mechanism 18 advantageously comprises a first adjustment 19 which allows to adjust the projection of the hooked end of the arm 15 with respect to the plate 11 (in the forward/backward direction when the device is on the furniture) and a second adjustment 20 which allows to adjust the inclination of the arm between the two wings, in a plane parallel to the plane of the two wings (and therefore parallel to their fixing plane) and around a hinging zone near one of its ends 17 which is opposite the hooked end.
  • the inclination is extrinsic, therefore substantially in the vertical plane when the device is mounted on a piece of furniture.
  • FIG. 2 also shows the other side of device 10 with respect to that shown in figures 1 and 4.
  • the first adjustment 19 can advantageously comprise a screw 26 which controls the sliding of the arm.
  • a sliding screw 26 screws into a threaded seat 27 at the end 17 of the arm 15.
  • the threaded seat 27 can be made by means of a threaded nut appropriately constrained to the end 17 of the arm.
  • the head 26b of the screw 26 is constrained to allow the axial rotation of the screw but not its axial sliding.
  • the screw 26 and threaded seat 27 create a screw-nut coupling so that when the screw 26 is manually rotated, the aforementioned forward/backward sliding of arm 15 is produced.
  • the second adjustment 20 can in turn advantageously comprise a screw 28 which operates a limit switch limiting the inclination movement of the arm.
  • the inclination screw 28 screws into a threaded seat 29 present on the plate, which can be made by means of a threaded nut suitably constrained to the plate 11 .
  • the screw 28 and threaded seat 29 create a screw-nut coupling so that when the screw 28 is manual rotated, an axial sliding of the screw 28 is produced, whose tip end 30 pushes against an arched return 31 forming the movable limit switch of abutment to the upward movement of the arm 15.
  • the maximum upward inclination of arm 15 is thus established when it rotates around its end opposite the hook (e.g., around the nut 27, constrained to the arm 15 with enough slack to allow the inclination).
  • the entire kinematic adjustment mechanism can be made so as to avoid protruding from the upper plane of the two wings.
  • the recessed zone can be suitably perforated so that the adjustment mechanism can be arranged astride the thickness of the plate in the recessed zone. This allows to reduce the thickness of the device and to have a shallower housing recess in the furniture.
  • the device 10 will be, as the person skilled in the art can easily imagine, made in two specular versions
  • the corresponding plates 21 have been fixed to the wall, all that is needed is to hook the ends of the two arms to the brackets and act on the screw heads with a suitable tool for the fine adjustment of the position of the furniture, as is substantially known to the person skilled in the art.
  • the arm 15 is shown in figures 1 and 3 in its adjustment position with the hook end more extracted from the plate 11 .
  • the screws can be manoeuvred with a suitable known tool, e.g., a screwdriver or a suitable wrench, depending on the shape of the heads 26b and 28b of the two screws 26 and 28.
  • a suitable known tool e.g., a screwdriver or a suitable wrench
  • the head of the two screws may have a crossed seat or hexagonal recess to be engaged by a Phillips screwdriver or Allen wrench.
  • FIG 2 Also shown in figure 2 are the faces 32 and 33 of the wings 12 and 13, which are intended to be arranged against the side of the furniture when device 10 is mounted on the furniture and which therefore form the resting surfaces of the device to the side of the furniture (as also clear from figure 1 ).
  • Respective elements 34, 35 protrude from such resting surfaces of the wings 12 and 13, the elements being intended to penetrate the furniture wall to lock the device in place.
  • the elements 34 and 35 consist of a first rigid section 38 close to the wings (e.g., made in a single piece on the same wings 12 and 13) and a second section or end section 39 which is yielding, viz., which has at least a side surface consisting of a yielding pad (e.g., in plastic).
  • the first rigid section 38 allows it to withstand the vertical loads, even high ones, developed by the weight of the furniture on the device 10, discharging them into the shoulder of the furniture, while the second yielding section 39 forms a pressure engagement pad in the holes in the furniture and which prevents the free extraction of the elements 34, 35 once they have been inserted into the receiving holes 36, 37 in the furniture.
  • the pads of the yielding section 39 can have side ribs shaped like arrows in the direction of insertion into the holes, as can be seen by way of example in figures 2 and 3.
  • the wall support bracket 21 can preferably comprise a central body 40 with at least one window 41 , which makes the coupling seat accommodating the hooked end 16, and wings 42 and 43 provided with respective slots 44, 45 for fixing the support bracket to the wall 22, for example by means of known expansion dowels and screws (not shown, being easily imaginable by the person skilled in the art).
  • the window 41 can be obtained near the side edge of the support bracket, and preferably have a side wall to prevent accidental lateral sliding of the hook from causing the device 10 to leave the bracket, resulting in the furniture falling.
  • the bracket can also be made with an open side wall or even, simply, with an upper hooking tooth 141 which makes the housing seat for the hooked end of the device, as schematically shown in figure 5 for the bracket indicated with 121.
  • Such a bracket can, for example, be made from a suitably shaped profile.
  • bracket 121 is shown together with an alternative solution 110 of the device but, of course, the bracket 121 can also be employed with the device 10, as the device 110 can also be used with the bracket 21 .
  • a device according to the invention can be used independently of the type of bracket to which it is to be hooked, as can easily be imagined by the person skilled in the art on the basis of the description given here.
  • the shape of the device obliges the support bracket, whatever it may be, to be positioned in a position which interferes with the rear edge of the shoulder of the furniture and obliges making a seat dug into such a side edge and which is in addition to the seat dug into the side wall of the furniture to accommodate the recessed central part 14 of the device 10.
  • the arm 15 is made with a hooked end which is offset with respect to the body of the arm, in order to be in an offset hooking plane and which is spaced, in the direction opposite the recess formed by the intermediate zone, from the fixing plane identified by said two coplanar wings.
  • the arm is shaped bent so as to move away from the plane identified by the resting faces 32, 33 of the wings 12 and 13 and in the direction opposite such faces.
  • the bent and offset end can be in a plane parallel to that of the arm body present in the intermediate recessed zone 14.
  • the hooked terminal end 16 is therefore outside the thickness of the side shoulder of the furniture, as can be seen for example in figure 3.
  • Such an offset end part 16 will be sized to be long enough to exit from the back of the furniture starting from the edge of the recess 47 towards the back, without however interfering with any drawers, which generally do not arrive in the rear against the back.
  • the end part 16 could have a length comprised between 15 and 40mm, also depending also on the specific hooking requirements.
  • the shape of the arm thus allows to simplify the installation whatever wall bracket is employed, the device according to the invention allowing, even if recessed in the shoulder of the furniture, to fix the brackets to the wall outside of the interference with the shoulders of the furniture.
  • the staggering (indicated with 'a' in figure 3 and measured between the surface of the wings 12, 13 forming their resting plane on the furniture and the face of the hooked end of the arm facing in the same direction as such a plane) is at least equal to, and preferably greater than, the minimum established distance (indicated with 'b' in figure 3 and figure 5) desired to be maintained between the hooked end of the device and the side edge of a wall mounting bracket.
  • such a distance ' b' will advantageously be the distance between the side wall 48 of the bracket 21 which is intended to face the shoulder of the furniture carrying the device 10 (i.e., towards the plane of the wings intended to be rested and fixed to the furniture) and the close side edge 49 of the window 41 .
  • the minimum distance 'b' can be that which is desired to be maintained between the edge or side wall 148 of the bracket and the position 149 of the side face of the hooked end which faces the shoulder of the furniture (i.e., towards the resting and fixing plane of the wings to the furniture) when the hooked end is hooked on the bracket.
  • a wall-fixing bracket can be kept correspondingly farther away from the shoulder of the furniture, as is clear from the example in figure 3, and does not interfere with the rear edge of the shoulder.
  • the offset 'a' can be comprised between 2 and 20 mm, and preferably be around 5 mm.
  • the arm 15 can advantageously be made in the form of a fork directed towards its hinging point, so as to embrace the plate in the recessed zone on its two opposite faces. This allows to have a good torsional strength and improved guidance for the movement of the arm on the plate.
  • Figures 5 and 6 show two embodiment variants of the device 10.
  • the kinematic mechanism for adjusting the position of the arm (respectively arm 115 and 215, with offset hook ends 116 and 216) is manoeuvrable by means of a tool which can be engaged to the kinematic mechanism from a direction perpendicular to the extension plane of the fixing wings of the device, rather than from a direction substantially parallel to such a plane as is the case in the embodiment of figures 1 -4.
  • the devices 110 and 210, as well as the hooking plate 21 and furniture inserts remain substantially the same as those already described above with reference to the device 10 and will therefore not be further described in detail here.
  • the device 110 has the kinematic mechanism 118 in which the first adjustment 119 is substantially equal to the adjustment 19 described above, but the screw 126 has the head 126b in the form of a bevel gear to engage in a complementary idle bevel gear 150 arranged with the rotation axis at right angles with respect to the rotation axis of the screw 126 and normal to the fixing plane of the two wings 112 and 113 between the intermediate zone 114.
  • the device 110 also has the second adjustment 120 which is similar to the adjustment 20 of the previous embodiment but has a slider 130 internally threaded to be engaged and moved by the rotation of a screw 128 screwed therein and held stationary in the axial direction by means of a suitable constraint on the device.
  • the slider 130 pushes against an arched return 131 , which forms the movable limit switch of abutment to the upward movement of the arm 115.
  • the head 128b of the screw 128 is in the form of a bevel gear to engage in a complementary idle bevel gear 151 arranged with the rotation axis at right angles with respect to the rotation axis of the screw 128 and normal to the fixing plane of the wings 112 and 113.
  • the two idle gears 150 and 151 centrally have an engagement seat for their rotation with a suitable known tool, e.g., a screwdriver or a suitable wrench, as described for the device 10, but directed according to the above- mentioned perpendicular engagement direction, as shown by way of example in figure 5 for a screwdriver tool.
  • a suitable known tool e.g., a screwdriver or a suitable wrench
  • the further embodiment of figure 6 with the plate 211 , wings 212 and 213 and intermediate zone 214 the same as the previous embodiments, envisages a further simplification with respect to the solution of figure 5, since the idle bevel gears 150 and 151 are not present and the bevel gears on the screw heads are made with teeth which directly match the shape of the tip of a Phillips screwdriver (as shown in section in figure 6).
  • the device 210 comprises a suitable guide block 252 above the bevel gears on the screw heads 226 and 228 of the kinematic adjustment mechanism 218, otherwise the same as the adjustment device 118 described above.
  • the position of the arm (indicated with 215 in figure 6) is thus adjusted simply by inserting a Phillips screwdriver into the suitable seats in the guide block 252, as shown by way of example in figure 6. Similar to the embodiment of figure 5, the rotation of the screwdriver controls the rotation of one or the other screw 226 or 228 through the corresponding bevel gear in the screw head. The screw 226 will move the arm 215 back and forth, while the screw 228 will move the slider 230, which, acting on the return 231 , will establish the inclination limit switch of the arm.
  • brackets of various types can also be used with brackets of various types and, for example, with the bracket 21 or with the bracket 121 .
  • the fixing means of the devices according to the invention may be different from those shown and provide expansion dowels, screws, etc., as now easily imaginable by the person skilled in the art.
  • the size and proportions of the various parts of the devices can also vary according to preferences and specific requirements.
  • the bracket to be fixed to the wall for hooking the device according to the invention thereon can also be different from what is shown and for example can be extended between the two shoulders of the furniture to make both hooking seats for two mirrored devices according to the invention fixed to opposite shoulders of a piece of furniture.
