[0001] The present invention relates to a process to prevent an undesired accidental rotation
of a hight-regulating screw and a depth-regulating screw of a perfected hanging bracket
for the assembly of wall-cupboards, such as, for example, wall-units and base-units
for kitchens and bathrooms, and other items of furniture which must be cantilever-assembled
on a supporting wall.
[0002] Metal hanging-brackets structurally consisting of a shaped base having a substantially
rectangular configuration, are known.
[0003] A bracket protruding from the base, with a hook-shaped end, is assembled on said
base, in an adjustable position.
[0004] The base is designed for being fixed to a shoulder of the wall-cupboard by fixing
means, such as screws and/or pressure- or expansion- pins, or other fixing means,
whereas the hook is destined for being hooked to a support - a dowel, plate, shaped
bar, or similar product - fixed to the wall.
[0005] Two regulation mechanisms cooperate with said bracket, suitable for regulating the
height (vertical) and depth, respectively, of the bracket itself.
[0006] The wall-cupboard can be assembled to a wall in the desired position, also with respect
to adjacent cupboards.
[0007] A hanging-bracket of this type is described and illustrated, for example, in international
patent applications
PCT/EP2009/005627 and
PCT/EP2009/005628 to which reference should be made for clarifications and which should be considered
as being an integral part of the present patent application.
[0008] Hanging-brackets of the type briefly described above, are fixed to the shoulder of
the piece of furniture, either manually or using an automated assembly line equipped
with a vibrating feeder, which serves for feeding the hanging-bracket in the correct
position, to the automatic fixing unit of the same to the shoulder of the cupboard.
[0009] As is well-known to experts in the field, the vibration of the vibrating feeder tends
to tighten or loosen (depending on the rotation direction, clockwise or anticlockwise,
of the vibrating feeder) the regulation screws of the height and depth of the above-mentioned
mechanisms with which the hanging-bracket is equipped.
[0010] This is a serious drawback, as said regulation screws of the height and depth of
the hanging-bracket, translate and acquire a position which is different from that
established by the manufacturer of the hanging-bracket for a correct use of the same,
for both manual or automatic fixing of the same to the shoulder of the cupboard, and
also for a simple, correct and rapid assembly of the cupboard to the support fixed
to the wall.
[0011] An objective of the present invention is to overcome the above drawback of the known
art, by providing a hanging-bracket with regulation mechanisms of the height and depth,
equipped with regulation screws whose position can in no way be accidentally modified
by the vibrations of a vibrating feeder, or similar tool.
[0012] This objective is achieved by a hanging-bracket having the characteristics specified
in claim 1 and enclosed sub-claims.
[0013] The structural and functional characteristics of the invention and its advantages
with respect to the known art will appear clearly understandable from the following
description referring to the enclosed drawings, which illustrate embodiment examples
of the invention itself.
[0014] In the drawings:
- Figure 1 is a raised view taken according to the arrow A of figure 4;
- Figure 2 is a raised view taken according to the arrow B of figure 4;
- Figure 3 is a raised view taken according to the arrow C of figure 1;
- Figure 4 is a raised view taken according to the arrow D of figure 1;
- Figure 5 is a plan view taken according to the arrow E of figure 1;
- Figures 6 and 7 are two perspective views illustrating the hanging-bracket of figures
1-5;
- Figure 8 is a sectional view taken according to the line VIII-VIII of figure 1;
- Figures 9, 10 and 11 are enlarged sectional details illustrating processing phases
of the hanging-bracket according to the invention; and
- Figures 12 and 13 are perspective views similar to figures 6 and 7, illustrating the
same hanging-bracket equipped with different means for fixing it to the shoulder of
the piece of furniture.
[0015] With particular reference to figures 1-8 of the drawings, a metal hanging-bracket
produced according to the invention is indicated as a whole with 20 and is structurally
composed of a shaped base or shell 21, having a substantially rectangular configuration,
on which a bracket 22 is assembled in an adjustable position (with the possibility
of rotation and translation).
[0016] As can be clearly seen from the drawings, said bracket 22 comprises two opposite
sides or flanks 23, which envelop the base 21, protruding from the latter with a hook-shaped
end 24.
[0017] Two regulation mechanisms cooperate with said bracket 22, a first 25 for regulating
the height, a second 26 for regulating the depth.
[0018] The hanging-bracket thus structured is fixed to the shoulder of the cupboard, for
example by means of self-threading screws (not shown) which pass through holes 27
of the base 21.
[0019] The hook 24, on the other hand, is suitable for being hooked to a support fixed to
the wall, for example a dowel, a plate, a bar, or equivalent means.
[0020] More specifically, the first height (vertical) regulation mechanism 25 comprises
a lunette 28 guided to slide on the base 21. The lower end of said lunette 28 acts
on the bracket 22, whereas the upper end cooperates with a hight-regulation screw
29 which is screwed onto a nut 30 blocked on the base 21.
[0021] Said height-regulation screw 29 has a head 31 with an imprint for an operating tool.
The stem of the height-regulation screw 29 is supported by means of arched supports
32 of the base 21.
[0022] The second mechanism for regulating the depth 26 consists of a depth-regulation screw
33 acting on the end of the bracket 22 opposite the hook 24.
[0023] Said depth-regulation screw 33 is screwed onto a nut 34 blocked on the bracket 22.
The stem of the depth-regulation screw 33 is supported by the bracket 22 and by an
arched support 35 of the base 21, said support 35, together with end teeth 39 of the
base 21 itself, defining a containment seat 40 for the head 41, with an imprint 42,
of the depth-regulation screw 33.
[0024] From the above description with reference to Figures 1-7, and as is well-known to
experts in the field, once the cupboard has been assembled to the wall, the rotation
of the height-regulation screw 29 will cause an oscillation around the area 43 of
the bracket 22 in the direction of the arrow F, whereas a rotation of the depth-regulation
screw 33 will cause a translation of the same arm 22 in the direction of the arrow
F1.
[0025] The functioning of the height and depth regulation mechanisms of the hanging-bracket
in question is also illustrated and described in detail in the above-mentioned international
patent applications PCT/
EP2009/005627 and
PCT/EP2009/005628.
[0026] According to the invention, an undesired accidental rotation (screwing or unscrewing)
of the screws 29 and 33 - caused, for example, by a vibrating feeder - is prevented,
by completely pulling the bracket 22 against the base (21) by tightening the depth-regulation
screw 33: this maneuver compels the bracket 22 to acquire the horizontal position
illustrated in figures 1 and 2 of the drawings. With the bracket 22 in an exactly
horizontal position, the height-regulation screw 29 cannot be screwed (as it is pushing
the lunette 28 and consequently the bracket 22, which is blocked in a horizontal position
by the tightening of the depth-regulation screw 33) and cannot be unscrewed (as, thanks
to a deformation d in its threading which is engaged with the nut 30, it creates friction
with the rotation which prevents the same).
[0027] Said deformation d in the threading of the height-regulation screw 29 can be clearly
seen in the enlargement of figure 11.
[0028] As can be clearly seen in figures 9 and 10, the deformation d is obtained by means
of a punch 36 and a counter-punch 37 between which the hanging-bracket 20 is positioned.
[0029] Figures 12, 13 show a hanging-bracket completely identical to that illustrated in
figures 1-11, with the exception of the fixing means to the shoulder of the cupboard;
pressure pins 38 (so-called doubels) are in fact envisaged instead of holes 27 for
screws.
[0030] The objective indicated in the preamble of the description, has therefore been achieved.
[0031] The protection scope of the invention is defined by the following claims.
1. A process to prevent an undesired acidental rotation of a height-regulating screw
(29) and a depth-regulating screw (33) of a perfected hanging bracket (20) for the
assembly of wall-cupboards wherein said perfected hanging bracket (20) comprises,
in combination:
a shaped base (21) on which a bracket (22) is assembled, whose position is adjustable,
with the possibility of rotating and translating, said bracket (22) having a hook-shaped
end (24) protruding from said base (21), two regulation mechanisms, the first (25)
for adjusting the height and a second (26) for adjusting the depth, cooperating with
said bracket (22), the first mechanism (25) for regulating the height comprises a
lunette (28) guided to slide on the base (21), the lower end of said lunette (28)
acting on the bracket (22) whereas the upper end cooperates with a height-regulation
screw (29), the second mechanism (26) for regulating the depth, consists of a depth-regulation
screw (33) which acts on the end of the bracket (22) opposite to the hook (24), characterized in that said height-adjustable screw (29) has a deformation in it's threading in order to
prevent an undesired accidental rotation (screwing or unscrewing) of said height-regulation
screw (29) and said depth-regulation screw (33) by completely pulling the bracket
(22) against the base (21) by tightening the depth-regulation screw (33), said manoeuvre
compelling the bracket (22) to acquire a horizontal position, the height-regulation
screw (29) cannot therefore be screwed by pushing the lunette (28) and consequently
the bracket (22), which is blocked in a horizontal position by the tightening of the
depth-regulation screw (33) and cannot be unscrewed as, thanks to a deformation (d)
in its threading, it creates friction with the rotation which prevents it.
