[0001] The present invention relates to a wall assembly group for a cantilevered piece of
furniture, whether it be a wall cupboard or a so-called base, forming part for example
of furniture for kitchens, bathrooms or living rooms.
[0002] Hereinafter, for the sake of simplicity, the term wall cupboard will be used in general.
[0003] The type of groups to which the present invention relates is that provided with a
plaque which is fixed to the wall or onto a bar (in turn fixed to the wall) and equipped
with a hooking device fixed to the wall cupboard (so-called hanging bracket) which
is engaged on the plaque for hanging the cupboard.
[0004] The fixing of cupboards to the wall is currently more widely used in household furnishing
solutions, also for hanging furniture which is close to the floor.
[0005] The necessity is therefore increasingly felt for assembly groups which are equipped
with an anti-disengagement system, suitable for preventing an undesired disengagement
of the hooking means from the plaque, due to a force from below which tends to raise
the cupboard; this situation could arise for example when the cupboard is unexpectedly
pushed upwards from below.
[0006] A known solution, described in patent application
MI2009A000699, of April 24, 2009, envisages that the anti-disengagement system "automatically" enters into function
when the hooking means of the hanging bracket are inserted into the plaque.
[0007] This "automatic" anti-disengagement system exerts this function by means of an elastic
element, such as a metallic lamina or spring, which moves, under thrust, to allow
the hooking means to pass into an engagement seat and then returns (elastically) to
its initial position to prevent the hooking means from becoming disengaged from their
seat.
[0008] These "automatic" anti-disengagement systems, however, have the common drawback that,
during a dismantling phase of the cupboard, it is necessary to act continuously and
individually on each plaque to disable the "automatic" anti-disengagement system;
this is normally effected by an operator who acts with a tool on the elastic element,
first moving it and then keeping it in its position of non-engagement with the above
hooking means.
[0009] It should be noted that wall cupboards are often provided with a plurality of hooking
means and plaques: this requires the need for an operator for each plaque, who acts
on the "automatic" anti-disengagement system of the same.
[0010] In short, if a wall cupboard is provided (for example) with four plaques, four operators
are required, who must simultaneously act on the anti-disengagement system of each
plaque to allow the non-engagement of the wall cupboard.
[0011] As can be understood, this solution is not practical and should be avoided, without
however renouncing the safety provided by the presence of anti-disengagement systems.
[0012] Another drawback is linked to the autonomous intervention of these "automatic" anti-disengagement
systems: when using them, in fact, the control the operator indirectly has in the
assembly is lost: if the activation of the anti-disengagement system is automatic,
a malfunctioning can arise deriving from an incorrect hooking, whereby the assembler
is unaware of the unsuccessful intervention of the anti-disengagement system.
[0013] In this case, even if the wall cupboard can remain suspended to the wall, it is neither
fixed correctly, nor is the anti-disengagement system functioning, with the result
that due to an upward force from below, it can easily become unhooked from the wall
with consequences that can be easily predicted.
[0014] The objective of the present invention is to provide an assembly group for wall cupboards
which can overcome these drawbacks.
[0015] This objective is achieved by an assembly group according to the first claim and
optionally provided with the advantageous characteristics of the enclosed sub-claims,
which are an integrant part of the present description.
[0016] The idea at the basis of the present invention is to provide a wall assembly group
of a wall cupboard, of the type comprising: a plaque to be fixed to a wall, a hanging
bracket that can be coupled with said plaque and anti-disengagement means that can
be moved to a first stable position in which, when the hanging bracket is fixed to
the plaque, they intercept the hooking means to prevent the decoupling of the latter
from the plaque, and wherein the anti-disengagement means can also be moved to a second
stable position, in which, when the hanging bracket is fixed to the plaque, they release
the hooking means to allow the decoupling of the latter from the same plaque.
[0017] In this way, as can be seen, the drawbacks of the known systems discussed above are
overcome: a single operator, in fact, when the wall cupboard is being dismantled,
can act at different times on all the anti-disengagement means to bring them to a
condition of non-engagement, subsequently decoupling the hooks from the plaques, thus
removing the cupboard.
[0018] According to other advantageous characteristics, during the assembly phase, the operator
can act positively (i.e. effect a real action) to activate the anti-disengagement
means, thus being able to verify the correct activation and assembly.
[0019] The structural and functional characteristics of the invention, as also its advantages
with respect to the known art, will appear more evident from the following description,
referring to the enclosed drawings, which show possible practical embodiments of the
invention itself.
[0020] In the drawings:
- figures 1 and 2 show a first embodiment of the group according to the present invention,
with the anti-disengagement means respectively in a first stable interception position
of the hooking means and in a second stable position in which said hooking means are
free;
- figures 3 and 4 show a second embodiment of a group according to the present invention,
with the anti-disengagement means respectively in a first stable interception position
of the hooking means and in a second stable position in which said hooking means are
free;
- figures 5 and 6 show a third embodiment of a group according to the present invention,
with the anti-disengagement means respectively in a first stable interception position
of the hooking means and in a second stable position in which said hooking means are
free.
[0021] With reference to the enclosed figures 1 and 2, these illustrate a first embodiment
of an assembly group 1A of wall cupboards.
[0022] The group 1A comprises a hanging bracket 2A which can be fixed to the wall cupboard
and a plaque 3A which can be alternatively fixed to the wall or a bar (not shown)
in turn fixed to the wall.
[0023] The hanging bracket 2A is of the known type and can comprise a simple hook (not shown)
or hooking means (such as those shown) wherein the position of the hooking end 20A
can be regulated, for example in a horizontal direction (or depth) and/or vertical
direction (or height).
[0024] Hooking devices 2A or hanging brackets of the type described above are known in themselves
and are consequently not described in greater detail.
[0025] The plaque 3A, in the example described hereunder, is of the type suitable for being
applied to a wall by means of screws or pegs: for this purpose, it is provided with
fixing holes 31A in which the screws V screwed to the wall, are engaged.
[0026] The plaque 3A is also provided with at least one seat 32A in which the hooking end
20A of the hanging bracket 2A is inserted: in this embodiment, the seat 32A is a window
into which the hooking end 20A passes, subsequently resting on its lower edge.
[0027] The plaque 2A comprises anti-disengagement means 30A which in this solution comprise
a lamina 34A provided, at least on part of one side, with actuating means, which in
this case are consecutive saw-toothed notches 35A.
[0028] The functioning of the anti-disengagement means 30A is evident from simply observing
figures 1 and 2: the lamina 34A can be moved from a first stabile position (that of
figure 1) in which it intercepts part of the passage span of the window 32A and therefore
prevents disengagement of the hooking ends 20A from their engagement with the edge
of the window 32A.
[0029] The lamina 34A can also be moved to a second stable position (that of figure 2) in
which it substantially frees the whole passage span of the window 32A consequently
freeing the hooking end 20A which, free to move upwards, can be disengaged from the
edge of the window 32A.
[0030] The activation of the lamina 34A, in order to cause its movement between the first
and second position, is obtained in this example by means of a tool U, for example
a screw-driver, which acts on the consecutive saw-toothed notches 35A: the rotation
of the screw-driver in one direction or another causes the linear translation of the
lamina 34A in a sliding seat 36A situated on the plaque 3A.
[0031] In this way, the second position (figure 2) is stable, in the sense that it can be
maintained without any force applied to the anti-hooking means 30A, and also the actuation
of the anti-disengagement means 30A (both in the movement from the first to the second
position, and vice versa) undergoes a positive action on the part of the operator,
who must act with the tool U to move the lamina 34A.
[0032] A second embodiment of the group 1B is shown in the enclosed figures 3 and 4.
[0033] In this embodiment, the same parts as the first embodiment are indicated with the
same numbers followed by the letter B, and consequently, for the sake of brevity,
no further mention will be made thereof.
[0034] The difference between the first embodiment 1A and the second embodiment 1B relates
to the different embodiment of the anti-disengagement means 30A and 30B.
[0035] In this second embodiment, in fact, the anti-disengagement means 30B comprise an
elastic lamina 34B which can be activated in a direction towards or away from the
edges of the window 32B by means of the actuation means 35B which, in this case, are
beads screwed onto the plaque 3B.
[0036] The lamina 34B is engaged on one side with an engagement seat 36B of the plaque 3B,
whereas the free end extending towards the window 32B is free to bend.
[0037] The bead 35B, when screwed or unscrewed, acts on the lamina 34B to cause the bending
of its free end which moves so as to intercept (as in figure 1) or free (as in figure
2) the hooking end 20B, which is therefore respectively blocked in the window 32B
or free to become disengaged from the latter.
[0038] As can be immediately observed, also in this case, both the first and second position
that can be acquired by the lamina 34B, are stable, in the sense that the presence
of an operator for holding it in the second position is not necessary, as for this
purpose, it is sufficient for the bead 35B to be screwed.
[0039] Finally, a third embodiment of the group 1C is illustrate in figures 5 and 6.
[0040] In this third embodiment, the same parts as the first and second embodiment are indicated
with the same numbers followed by the letter C, and consequently, for the sake of
brevity, no further mention will be made thereof.
[0041] The difference between the other embodiments and the third embodiment 1C relates
to the different embodiment of the anti-disengagement means 30C of the latter.
[0042] In this, in fact, the anti-disengagement means 30C comprise a lamina 34C which, analogously
to that of the first embodiment, can be moved from a first stable position (that of
figure 5) in which it intercepts part of the passage span of the window 32C and therefore
prevents disengagement of the hooking end 20C from engagement with the lower edge
of the window 32C, and a second stable position (that of figure 6) in which it substantially
frees the whole passage span of the window 32C thus freeing the hooking end 20C from
which, free to move upwards, it can become disengaged from the edge of the window
32C.
[0043] For this purpose, the lamina 34C slides with respect to the plaque 3B inside the
engagement seat 36B of the plaque 3B.
[0044] In this example, the actuation means 35C comprise gripping flaps which extend perpendicularly
to the body of the lamina 34C and which can be manually held to cause the movement
of the lamina 34C itself, thus avoiding the use of tools.
[0045] As can be immediately observed, also in this case, both the first and second position
that can be acquired by the lamina 34C, are stable, in the sense that the presence
of an operator for holding it in the second position is not necessary.
[0046] A further advantageous characteristic which is common with all the variants 1A, 1B,
1C, can also be noted: the plaque 3A, 3B and 3C comprises two windows 32A, 32'A or
32B, 32'B or 32C, 32'C adjacent to each other, so that the end 20A, 20B, 20C of the
hanging bracket can be housed in one or other depending on the assembly requirements.
[0047] In the first and third variant, the laminas 34A and 34C can be moved in the respective
seats 36A and 36C and have an extension which is such that they are alternatively
in the first position with respect to one window 32A and 32C and in the second position
for the other window 32'A and 32'C.
[0048] The objectives mentioned in the preamble of the description have therefore been achieved.
[0049] Numerous variants to what has so far been described are also possible, all to be
considered as being an integral part of the present invention.
[0050] For example, even if anti-disengagement means which intercept at least part of the
passage span of a window in which the hook is housed have been described so far, they
could comprise different forms, all available to experts in the field in the light
of what has been described so far.
