CONCEALED DEVICE FOR FITTING A WALL UNIT

Description

[0001] The present invention concerns a concealed device for fitting a wall unit.

[0002] Different devices are known for fitting a wall unit to an anchoring element on the wall, for example a bar, all adjustable.

[0003] The fitting device known from EP-A-0 555 924 comprises a plate designed to be fixed to the unit and a coupling element consisting of a head combined with a screw, which is connected to the plate and can engage in a support of the wall unit, for example a bar fixed to the wall.

[0004] This fitting device also has a first screw that acts between the plate and the coupling element to adjust the latter to a vertical position with respect to the plate and a second screw, the end of which is fitted with the coupling element, as said, for adjusting the distance between the coupling element and the plate.

[0005] The plate is provided with a number of fixing pins which extend along one side of it and along a portion located below the coupling element.

[0006] The plate is also provided with a number of holes for fixing screws, made all along the side opposite the plate with respect to the side that houses the fixing pins.

[0007] Devices of the type described, although able to perform the function for which they were designed, can be improved in a number of interesting and important ways.

[0008] In the first place, the devices described have an asymmetrical shape and as such are not particularly suitable for automatic handling.

[0009] Secondly, the particular shape of the plate of the device is not ideal as regards capacity to uniformly withstand the wall unit load.

[0010] The plate of the device is also excessively and unnecessarily bulky.

[0011] The aim of the present invention is, therefore, to produce a concealed device for fitting a wall unit that solves the above problems and permits the automatic fitting of said devices.

[0012] A further aim of the present invention is to produce a fitting device with a particularly compact, rational and therefore economic shape.

[0013] These and other aims are achieved by a concealed device for fitting a wall unit, according to claim 1, which is referred to for the sake of brevity.

[0014] Further characteristics of this invention are defined, furthermore, in the subsequent claims.

[0015] Further aims and advantages of this invention will become clear from the following description and the attached drawings, provided only as an illustrative and non-restrictive example, in which:

• figures 11-13 are enlarged perspective views of the device illustrated in figures 1-10.

[0016] With particular reference to the figures mentioned, the concealed device for fitting a wall unit, according to the invention, is indicated overall by reference number 10.

[0017] The fitting device 10 comprises a plate 11, which is designed to be fixed to a wall unit, and a coupling element 12, connected to the plate 11 via a slide mechanism.

[0018] The coupling element 12 is designed to engage in a support of the wall unit fixed to the wall (not shown for the sake of simplicity), for example a bar.

[0019] The fitting device 10 comprises, furthermore, a first screw 13, which acts between the plate 11 and the coupling element 12, to adjust the latter to a vertical position with respect to the plate 11.

[0020] The fitting device 10 also comprises a second screw 14, the end of which is fitted with the coupling element 12, and which can be used to adjust the distance between the coupling element 12 and the plate 11.

[0021] More in particular, the first screw 13 and the second screw 14 are both fitted on a slide 18, which can run between guides 19. The slide 18 is moved by reaction of the screw 13 against the stop 20.

[0022] The plate 11 is provided with a number of fixing pins 15, which are located on one side 16 of the device 10, symmetrically with respect to a centre line of the fitting device 10.

[0023] The fixing pins 15 are located all along one side 16 of the plate 11, and are obtained from the latter, as can be clearly seen in figures 11-13, by means of punching, drawing and forming. In addition, the side pins 15, or end pins, are interconnected by a drawn stiffening rib 15a.

[0024] On the same side 16, there are also holes 17 for the fixing screws of the fitting device 10.

[0025] It should be noted that the plate 11 comprises, in addition to the side that houses the fixing pins 15 and the holes 17 for the fixing screws, a further three sides forming a basically flat edge 21.

[0026] The particular shape of the fitting device 10, and in particular of its flat edge 21, permits automatic conveying of the same to the assembly area, as shown in figures 7-10.

[0027] More in particular, the devices 10 are conveyed by a feeder 22, shown schematically in figures 7-8 and in figure 10; this feeder is provided with apertures 23 for the flat edges 21 of the plate 11.

[0028] Finally, each device 10 is conveyed, for example by means of a robot and/or a plunger (not shown for the sake of simplicity), so that its fixing pins 15 fit into corresponding holes 25 on the back 24 of a wall unit.

[0029] Furthermore, the fact that the fixing pins 15 and the holes 17 for further fixing screws are located on one side of the plate 11, symmetrically with respect to a centre line of the fitting device 10, permits ideal distribution of the wall unit load. This is due also to the fact that the slide 18, fitted with the adjustment screws 13, 14 is contained in the same space as the pins 15.

[0030] The above description provides a clear illustration of the characteristics of the concealed device for fitting a wall unit subject of the present invention; likewise, the advantages are evident.

[0031] Finally it is clear that numerous variations can be made to the concealed device for fitting a wall unit, subject of this invention, without deviating from the scope of the appended claims.

[0032] In practice, the details illustrated may be implemented in any materials, forms and dimensions according to requirements and the same may be replaced by other technically equivalent means.
