Description

Wall hanger for furniture.

Field of the Invention

This invention concerns a device of hardware for furniture hanging on a wall and equipped with height adjustment capacity, in front inclination and, of course, in lateral displacement.

Prior art

For the hanging wall of furniture is known a great variety of devices included in the same field of which is the subject of the present invention.

Basic conditions on these devices are that are hidden from view and that, however, are reasonably accessible to drive regulations that allow the proper alignment of the furniture within a set of furniture or respect to its surroundings, once the furniture is  It is placed in its installation place.

The need to combine these conditions with the provision of the mechanisms producing regulations indicated and with the location limitations imposed by the own furniture design and its relationship with other furniture attached to it and that they must be regulated in the same way, all this makes the known solutions are complex in their constitution and installation and require to be accessible through openings made on the back wall of the furniture to allow regulation maneuvers when the furniture is attached to each other sideways; visual concealment and installation in these cases it is necessary to take advantage that the back wall of the furniture is set back generating a space between it and the wall in which you have to manage to install the hanger and hold it in the side and ceiling of the furniture (the back wall is generally flimsy for this purpose) through a mounting operation laborious and difficult to mechanize; when the back wall of the furniture  It is cloth only the hanger can be installed inside the furniture leaving to peek from behind (through the back wall) only the hook hanging on the anchor arranged in the wall.

Explanation of the invention and advantages

Faced with this state of affairs, the present invention advocates a furniture wall hanger solution that it consists of a set of pieces whose operative assembly offers a flattened constitution of thickness conveniently smaller than the width of a shroud that is executed vertically in the edge rear of the side panels of a piece of furniture with a height and depth duly greater than the respective height and width of a said set of pieces consisting of a base, a hook, a vertical adjustment spiral rotary cam, or cam spiral and a front regulation rotary ogival cam, or cam ogival; where, the base is attached to a mortise side and screwed to the bottom of it, the hook has a nail liable to be hung from a scarp support anchored to the wall hanging from the furniture, the spiral cam has its outline spiral supported on a lateral projection of the hook and rotated supported against the upper end of a vertical slide that is formed at the base and at the same time they have adjustment Sliding both the spiral cam itself and the lateral projection, the warhead rotates on a lower bearing that is formed at the base and is equipped with rotary and sliding adjustment between the vertical sides of a groove that is formed on said hook, while this ogival cam forms a disc that with rotary adjustment is embedded in a peripheral housing elastic that is formed on an elastic plate that is installed on the hook so that it is sandwiched between the body of the hook and wall of said shroud that is facing that in the one that is attached said base, whose disc has a toothed peripheral which is reciprocal of four jagged segments that are formed in said housing with radial throats that are interspersed between every two adjacent toothed segments, whose spiral and ogival cams are provided with first footprints for the application of a rotary drive tool, which are accessible through holes in the wall of the mortise corresponding to the interior of the furniture.

This proposed solution has the virtue of be installed recessed in the thickness of the side panels themselves of furniture, which at once solves numerous issues, such as they are: perfect visual concealment, where only the nail of the hook strictly necessary for its hook on the support escarpment anchored to the wall, resulting that, once assembled the furniture on the wall, all this is completely hidden from view; simple installation capable of simple machining by screwed to the bottom of the shroud; accessible maneuverability and simple through simple holes in the wall inside the shroud, allowing comfortable regulation independent of laterally attached furniture; release of interior space of the furniture for its essential purpose; applicability indistinctly for furniture with a cloth back wall or set back; indistinct applicability for right side panel or left of the furniture, since said spiral cam and ogival cam they are provided with second footprints for the application of a rotary drive tool.

These and other features of the invention They are detailed in the attached graphic representation.

Exhibition of a preferred embodiment

Regarding the drawings and references above listed, a preferred form is illustrated in the attached drawings of execution concerning the wall hanger of the invention.

As reflected in Figure 1, this hanger is embedded in the thickness of the side panel (5) of the furniture and consists in a set of parts whose operative assembly offers a flattened constitution of thickness conveniently smaller than the width of a mortise (6) that is executed vertically in the rear edge of the side panels (5) of a piece of furniture with a height and depth duly greater than the respective height and width of a said set of pieces consisting of a base (1), a hook (2), a vertical adjustment spiral rotary cam, or spiral cam (3) and an ogival rotary cam with front adjustment, o ogival cam (4); wherein, said base (1) is attached to a side of mortise (6) and screwed to the bottom of it, said hook (2) has a nail (7) that can be hung from a Escarpment support (8) anchored to the wall (9) of furniture hanging, said spiral cam (3) has its spiral contour supported by a lateral projection (10) of said hook (2) and rotates against the upper end of a vertical slide (11) that is formed in said base (1) and in which, at the same time, it is adjusted slidingly, said warhead (4) rotates supported on a bearing bottom (12) that is formed in said base (1) and is provided with rotary and sliding adjustment between the vertical sides (14) of a groove (13) that is formed on said hook (2), at time that this warhead (4) forms a disc (19) that with adjustment Rotary is fitted in a peripheral housing (27) elastic that is formed on an elastic plate (26) that is installed on the hook (2) so that it is sandwiched between the body of the hook (2) and the wall of said mortise (6) which is facing the one in which said base is attached (1), whose disk (19) has a peripheral teeth (28) that is reciprocal of four toothed segments (29) that are formed in said accommodation (27) with radial throats (30) that are sandwiched between every two adjacent jagged segments (29), whose spiral (3) and ogival (4) cams are provided with first footprints (15, 16) for the application of a rotary drive tool (22), which are accessible through holes (23) in the wall of said mortise (6) corresponding to the interior of the furniture.

The operative installation of the hanger in the mortise (6) only requires the screwing of the clamping screws (24) at the bottom of said shroud (6), whereby the nail (7) of the hook (2) is located at a strictly precise point for facilitate hanging on the scarp holder (8) that is anchored on the wall (9) and for which a regulation can be verified of the lateral position of the furniture.

Once this installation is done, the first respective footprints (15, 16) of the spiral (3) and ogival (4) cams face the holes (23) made for access and actuation of the tip of the drive tool (22) rotary; obviously, the individual holes (23) could transform into a single window that encompasses both. In this dot interests to review a particularity of the invention consisting of said spiral cam (3) and ogival cam (4) being provided with second footprints paths (20, 21) for the application of a rotary drive tool (22); this means that the hanger can be applied interchangeably for the panels lateral (5) left or right of the furniture, with the only difference that in one case the performance of the tool (22) will be above mentioned first footprints (15, 16) or on these second footprints (20, 21).

The consideration of this assembly (figures 1 and 2) in conjunction with the constituent details of the pieces individual (figures 3 to 13), enable rapid understanding of an operation that, for the rest, is quite simple.

For height adjustment, just turn (in counterclockwise direction according to figure 2) the spiral cam (3), a from the position of this figure 2, and the furniture will rise  progressively being this spiral cam (3) resting on the lateral projection (10) of the hook (2) and against the upper end of the slide (11) of the base (1), maneuver is whose amplitude it reaches until the point when the tip (25) of the spiral cam (3) butt against the lateral projection itself (10).

At maintenance of the regulated position contributes, on the one hand, the fact that said spiral cam (3) has its active edge provided with a parallel knurling (18) that, to facilitate the firm maintenance of the regulated position, it is reciprocal of a rib (34) that is carved in said projection side (10) of the base (1) of the hanger; and on the other hand, the fact that this spiral cam (3) has formed (figures 8 and 9) a prominence that protrudes laterally against the body of said base (1), prominence that exerts an extra transversal tightening to the body of the spiral cam (3). In addition, the adjustment of the spiral cam (3) at the base (1) prevents oscillations from occurring from his plane, to which the fact that his active flat body is sandwiched with rotary adjustment between bodies of the base (1) and the hook (2).

For the regulation of the frontal inclination of the furniture, just turn the ogival cam (4) so that one or the other of its symmetrical edges (according to which of the side panels of the furniture concerned) push against the corresponding vertical side (14) of the groove (13) of the hook (2) and, by reaction, rotating on the lower bearing (12) of the base (1), produce the swinging of the hook (2) and said swinging makes the furniture is regulated frontally. In this rotary maneuver of the ogival cam (4) there is an elastic jump like a ratchet between the peripheral teeth (28) of the disc (19) and the segments teeth (29) of the elastic plate (26), which is enabled by the elastic nature of the elastic plate itself (26) and the existence of radial throats (30) that are interspersed between these serrated segments (29); once the action is finished regulator, the elastic plate recovers its initial state and it produces the coupling between the peripheral teeth (28) and the serrated segments (29), which, favored in addition by the own weight of hanged furniture, firmly secure the point of established regulation and provides fine regulation in the regulation range possible.

Anti-swing stability of its rotation plane is in this case secured by the own adjustment of the ogival cam (4) in the lower bearing (12) of the base (1), and the existence of the own disc (19) that is sandwiched between the body of said hook (2) and the wall of said mortise (6) that faces that in which said base is attached (1).
