Description

[0001] The present invention relates to a cabinet suspending device according to the preamble of claim 1.

[0002] Cabinet suspending devices are used to ensure proper support and fixing of a piece of furniture to a wall, be it an actual cabinet closed at the front by one or more doors, an open cabinet or a shelf.

[0003] Cabinet suspending devices are intended to be fixed, built in or otherwise associated with the structure of a piece of furniture, generally at the rear portion/wall of the structure of the piece of furniture intended to be leant against a support wall.

[0004] Cabinet suspending devices must ensure a fast and stable attachment of the device to a hook or a support rail previously fixed to a wall. In addition, it is also required that the cabinet suspending devices are provided with adjustment means adapted to allow the adjustment of the cabinet suspending device position, and thus of the piece of furniture associated thereto, with respect to the hook or support rail both in vertical direction, i.e. in height, and in a direction perpendicular to the wall itself, i.e. away from or approaching such a wall.

[0005] As regards safety, the need to have a cabinet suspending device that can prevent undesired release from the hook or from the support rail is nowadays very much felt, particularly in case of a thrust acting on the piece of furniture from the bottom upwards, without complicating the structure of the cabinet suspending device as well as the hooking/release procedure to/from said hook or said support rail fixed to the wall.

[0006] The problem underlying the present invention is to devise a cabinet suspending device able to meet the above requirement while obviating the problems of the cabinet suspending devices of the prior art.

[0007] Such a problem is solved by a cabinet suspending device according to claim 1.

[0008] According to a further aspect, such a problem is solved by a kit for attaching a piece of furniture to a wall according to claim 14.

[0010] With reference to the accompanying figures, reference numerals 1 and 101 generally indicate a first embodiment and a second embodiment of a cabinet suspending device according to the invention.

[0011] The cabinet suspending device 1, 101 is intended to be applied to or integrated in the structure of a piece of furniture 2 and to engage with removable coupling a support rail 3 projecting from a wall for keeping the piece of furniture attached to the wall.

[0012] Said support rail 3 comprises an attachment portion 3a, intended to be attached to the wall that must support the piece of furniture 2, and an upper hooking portion 3b which cantilevers from the attachment portion 3a to be engaged in a reversible manner by the suspending device 1.

[0013] According to the illustrated embodiment, the above upper hooking portion 3b defines the upper end portion of the support rail 3 when such a rail is attached to the wall.

[0014] The above hooking portion 3b of the support rail 3 comprises a hook-shaped end portion to achieve a better engagement with the cabinet suspending device 1, 101.

[0015] The cabinet suspending device 1, 101 comprises

• a support structure 4 comprising a first side 10 intended to face towards the wall that must support the piece of furniture 2 when the cabinet suspending device 1, 101 is in use (see figure 1 and figure 9);
• attaching means 8 for the reversible attachment of the cabinet suspending device 1, 101 to the structure of a piece of furniture 2 to be supported on the wall;
• hooking means 7 comprising a free hooking end 7a for the reversible attachment of the cabinet suspending device 1, 101 to the upper hooking portion 3b of said support rail 3;
• coupling means interposed between the hooking means 7 and the support structure 4 to allow the free hooking end 7a of the hooking means 7 to be adjustably moved towards or away from said first side 10 of the support structure 4 to switch from a more rearward projecting position with respect to the support structure 4 to a projecting position more far away from the support structure 4, and vice versa,
• adjustment means 5 to adjust the distance of the free hooking end 7a of the hooking means 7 towards or away with respect to the first side 10 of the support structure 4, and
• an inner seat 11 extending vertically in said free hooking end 7a of the hooking means 7 starting from a lower opening, to allow such an inner seat 11 to engage from above an upper hooking portion 3b of a support rail 3 projecting from the above wall when the cabinet suspending device is in use to attach the piece of furniture 2 to such a wall (see figure 1).

[0016] According to the illustrated embodiment, the above support structure 4 is contained in a box-shaped body 10 from the first side of which the free hooking end 7a of the hooking means 7 protrudes.

[0017] The above coupling means interposed between the hooking means 7 and the support structure 4 are not illustrated in the figure for simplicity of representation. Preferably, such coupling means provide for a series of horizontal guides formed inside the box-shaped body 4 along which the hooking means 7 are guided in the longitudinal/horizontal direction X-X like a slider, so that the free end 7a of the hooking means 7 slides to and from the above projecting position more distanced from the support structure 4.

[0018] According to the illustrated embodiment, the above attaching means 8 are tabs projecting from the box-shaped body of the support structure 4 for engaging corresponding holes formed in the inner side of the walls of the piece of furniture 2. Alternatively, it is possible to provide structurally and/or functionally different attaching means, such as expansion bolts, screws, nuts, bolts, studs, pins and the like.

[0019] Advantageously, said hooking means 7 comprise a blocking tab 12 positioned in proximity of said lower opening of said inner seat 11. Said blocking tab 12 allows:

• partially obstructing the lower opening of the inner seat 11, leaving only a restricted passage free, and
• cooperating with the inner seat 11 in delimiting and defining a retaining seat in the free end 7a of the hooking means 7 suitable for preventing the hooking means 7 from being vertically pulled out from the hooking portion 3b of the support rail 3 inserted in said retaining seat when the cabinet suspending device 1, 101 is in use.

[0020] Preferably, when the cabinet suspending device 1, 101 is in use, the above free passage is positioned at the portion of the lower opening of the inner seat 11 that is most distal from the support structure 4, i.e. at the portion of the lower opening of the the inner seat 11 that is closest to the front side of the head end 7a and to the wall when the cabinet suspending device 1, 101 is in use.

[0021] Preferably, said adjustment means for adjusting the distance of the free hooking end 7a of the hooking means 7 towards or away from said first side 10 of the support structure 4 comprise a longitudinal adjustment screw 5 extending longitudinally in said support structure 4, said longitudinal adjustment screw 5 acting between the support structure 4 and the hooking means 7.

[0022] Preferably, said longitudinal adjustment screw 5 is accessible from the back side of said structure opposite said first side 10.

[0023] Preferably, said longitudinal adjustment screw 5 engages a threaded nut integral in translation with said hooking means 7, so that a rotation in one direction or in the opposite direction of said longitudinal adjustment screw 5 causes a relative displacement towards or away from the free end 7a of the hooking means 7 from the first side 10 of the support structure 4.

[0024] The cabinet suspending device 1, 101 further comprises a vertical adjustment screw 6 extending vertically in said support structure 4, such a vertical adjustment screw 6 acting between the support structure 4 and the hooking means 7 for vertically adjusting the height of the relative position of the hooking means 7 with respect to the support structure 4.

[0025] The hooking means 7 are supported and guided by the support structure 4 so as to be displaceable in an adjustable manner both in the longitudinal/horizontal direction and in the vertical direction with respect to the support structure 4 which is integrally attached to the piece of furniture 2, so as to allow an adjustment of the depth and in the vertical direction of the piece of furniture 2 attached to the wall by means of the cabinet suspending device 1, 101.

[0026] Preferably, the hooking means 7 are guided and supported by the support structure 7 so as to be able to slide reversibly in both the longitudinal/horizontal direction and in the vertical direction.

[0027] With specific reference to the first preferred embodiment of the cabinet suspending device 1 illustrated in figures 1 to 8, in the cabinet suspending device 1 the above blocking tab 12 is associated to said hooking means 7 so as to be displaceable in a relative manner with respect to the free hooking end 7a of said hooking means 7 to reversibly switch from:

• a position advanced towards the free hooking end 7a of the hooking means 7 in which it partially obstructs said lower opening of the inner seat 11 of the hooking means 7, so as to prevent vertically pulling out the hooking portion 3b of the support rail 3 inserted in the retaining seat when the cabinet suspending device 1 is in use, and
• a position away from the free hooking end 7a of said hooking means 7 in which the blocking tab 12 does not obstruct the lower opening of the inner seat 11 of the hooking means 7 allowing vertically inserting and/or pulling out the hooking portion 3b of the support rail 3 into/from the inner seat 3.

[0028] Preferably, the cabinet suspending device 1 further comprises actuating means which can be operated to move the blocking tab 12 towards and from the advanced position with respect to the free hooking end 7a of said the hooking means 7 when the cabinet suspending device 1 is in use.

[0029] Preferably, the blocking tab 12 is coupled to the hooking means 7 to be reversibly guided and supported by the hooking means 7 in the relative displacement from and towards said advanced position.

[0030] According to the preferred embodiment shown in figures 1 to 8, said blocking tab 12 is slidably coupled to and supported by the hooking means 7 (preferably by the bottom side of the hooking means 7) by means of a guide-slider coupling adapted to allow to reversibly move the blocking tab 12 from and towards said advanced position with respect to the hooking means 7.

[0031] Preferably, the cabinet suspending device 1 comprises elastic means 13 acting on the blocking tab 12 to push said blocking tab 12 with a predetermined elastic load towards said advanced position with respect to the hooking means 7.

[0032] According to the preferred embodiment shown in figures 1 to 8:

• the blocking tab 12 projects from the first side 10 of the support structure 7 parallel to the hooking means 7 (preferably along the lower side of the hooking means 7);
• the cabinet suspending device 1 comprises stop means for limiting the maximum advanced travel end position reached by the blocking tab 12 away from the first side 10 of the support structure 4, and
• the lower opening of the inner seat 11 of the hooking means 7 is not obstructed by the blocking tab 12 when the hooking means 7 are in said projecting position most distanced from said support structure 4 and the blocking tab 12 is in said maximum advanced travel end position.

[0033] Preferably, the lower opening of the inner seat 11 of said hooking means 7 surpasses the blocking tab 12, thus being not obstructed when the hooking means 7 are in said projecting position most distanced from said support structure 4 and the blocking tab 12 is in said maximum advanced travel end position.

[0034] Preferably, said stop means for limiting the maximum advanced travel end position reached by the blocking tab 12 comprises said vertical adjustment screw 6 against which said blocking tab 12 interferes in said maximum advanced travel end position, preferably said vertical adjustment screw 6 extends perpendicularly to said blocking tab 12 through a slot extended in said blocking tab 12 in the longitudinal direction in which said blocking tab 12 projects from said first side 10 of said support structure 4.

[0035] It should be noted that, in consideration of the above description in relation to the first embodiment of the cabinet suspending device 1, by acting on the longitudinal adjustment screw 5 it is possible to act on the hooking means 7 so as to bring them in said projecting position most distanced from the support structure 4. As described above, in this configuration (see figure 8) the lower opening of the inner seat 11 is not obstructed by the blocking tab 12 since said stop means, specifically the vertical adjustment screw 6, limit the maximum advanced travel end position reachable by the blocking tab 12 away from the first side 10 of the support structure 4. Therefore, at least in this configuration (see figure 8), the lower opening of the inner seat 11 is not obstructed by the blocking tab 12, so that the relative insertion or removal movement of the hooking portion 3b of the support rail 3 in the inner seat 11 through the lower opening thereof is not hindered by the blocking tab 12. Starting from this configuration (see figure 8) and acting on the longitudinal adjustment screw 5 so as to determine a retraction of the free head end 7a of the hooking means 7 towards the first wall 10 of the support structure, there occurs the partial obstruction of the above lower opening of the inner seat 11 by the blocking tab 12 (see figure 6), such closure being favoured by the action of the elastic means 13 acting on the blocking tab 12 pushing it towards the free hooking end 7a of the hooking means 7. Once the lower opening of the inner seat 11 is partially obstructed by the blocking tab 12 (as shown in figure 6), a further retraction of the free hooking end 7a of the hooking means 7 towards the first wall 10 of the the support structure 4, achieved by continuing to act on the vertical adjustment screw 6, causes a simultaneous retraction of the blocking tab 12 together with the hooking means 7.

[0036] Preferably, the attachment portion 3b of the support rail 3 defines with the blocking tab 12, more specifically with the lower side of the blocking tab 12, a shape coupling between inclined planes such as to cause a reversible retraction of the blocking tab 12 from said advanced travel end position towards a distanced position during the insertion of said attachment portion 3b of the support rail 3 in the lower opening of the inner seat 11, as shown in figure 7.

[0037] Such a retraction of the blocking tab 12 is useful to allow the attachment portion 3b of the support rail 3 to effectively fit into the inner seat 11 and is made possible by the presence of the elastic means 13 which, as a result of the thrust exerted by the end of the attachment portion 3b of the support rail 3 on the lower side of the blocking lug tab 12, allow the blocking tab 12 to retract momentarily towards the first side 10 of the support structure 4. As soon as the head of the attachment portion 3b of the support rail 3 surpasses the blocking tab 12, being inserted inside the inner seat 11, the elastic means 13 acting on the blocking tab 12 providing to bring such a tab to the position in which they partially obstruct the lower opening of the inner seat 11 (see figure 6).

[0038] In order to facilitate the above insertion, the head of the attachment portion 3b of the support rail 3 should be larger than the remaining part of the body of the attachment portion 3b so as to determine:

• a greater retraction of the blocking tab 12 towards the first side 10 of the support structure 4 when such a head is located at the height of blocking tab 12, and
• a subsequent advancement of the blocking tab 12 towards the free hooking end 7a of the hooking means 7, carried out due to the presence of the elastic means 13, once the above head has completely surpassed the blocking tab 12 fitting into the inner seat 11.

[0039] The above advancement of the blocking tab 12 towards the free hooking end 7a of the hooking means 7 constitutes an effective obstacle to the fact that the head of the hooking portion 3b of the support rail 3 may slip off from the inner seat 11 following the interference that is created between the head of the attachment portion 3b of the support rail 3 and the upper side of the blocking tab 12.

[0040] In order to increase the effectiveness with which the head of the hooking portion 3b of the support rail 3 is retained by the blocking tab 12 inside the inner seat 11, i.e. in order to have an effective interference of the head of the hooking portion 3b of the support rail 3 with the upper side of the blocking tab 12, the above head of the hooking portion 3b of the support rail 3 is preferably shaped as a hook or is folded, preferably away from said attachment portion 3a, i.e. in such a way that the hook or the folding are facing towards the first side 10 of the support structure when the suspending device is in use (see figures 6, 7 and 8).

[0041] With reference to the cabinet suspending device 1, it should be noted that the effective retaining action exerted by the blocking tab 12 on the head of the attachment portion 3b of the support rail 3, so as to firmly hold it inside the inner seat 11, allows preventing the piece of furniture 2 from being inadvertently disengaged from the support rail 3 as a result of an accidental thrust from the bottom upwards.

[0042] At the same time, the simplicity of the cabinet suspending device 1 is such as to determine the possibility of moving the blocking tab 12 from and towards said advanced position, in which it partially obstructs the lower opening of the inner seat 11, acting only on the usual adjustment screws, in particular on the longitudinal adjustment screw 5, without therefore causing any complication of use with respect to the cabinet suspending devices of the prior art.

[0043] With specific reference to the second preferred embodiment of the cabinet suspending device 101 shown in figures 9 to 15, it should be noted that, unlike what has been described in relation to the cabinet suspending device 1, in this embodiment the device is provided with a blocking tab 112, which is integral with the hooking means 7 in order to be integral with the free end 7a of the hooking means 7 towards or away from said first side 10 of the support structure 4.

[0044] Said blocking tab 112 is positioned at the lower opening of the inner seat 11 of the free end 7a of the hooking means 7, more precisely in spaced relation from said lower opening and outside the inner seat 11.

[0045] Preferably, the above free passage of the retaining seat, which is delimited and defined by the inner seat 11 and by the blocking tab 112, is oriented away from the first side 10 of the support structure 4, i.e. is oriented in such a way as to be directed at least partially towards the support rail 3 when device 101 is in use (see figure 11).

[0046] According to the preferred embodiment shown in figures 9 to 15:

• the lower opening of the inner seat 11 of the free end 7a of the hooking means 7 is oriented downwards, i.e. towards the lower side, of the cabinet suspending device 101 when said cabinet suspending device is in use, and
• the blocking tab 112 extends below said lower opening of the inner seat 11 substantially throughout the width of the lower opening itself.

[0047] Preferably, the side of the inner seat 11 closest to the free end 7a of said hooking means 7 is defined by a front inner wall 113 which forms an inclined plane with respect to the vertical, so as to be converging towards the first side 10 of the support structure 4 proceeding from the lower opening towards the bottom of the inner seat 11.

[0048] Due to the presence of the blocking tab 112, the cabinet suspending device 101 allows effectively preventing the piece of furniture 2 from inadvertently disengaging from the support rail 3 as a result of an accidental thrust from the bottom upwards.

[0049] In consideration of the presence of the blocking tab 112, the engagement or disengagement of the upper hooking portion 3b of the support rail 3 inside the inner seat 11 of the free hooking end 7a of the hooking means 7 is only possible by tilting upwards, by a predetermined angle α, the piece of furniture 2 and the cabinet suspending device 101 associated therewith with respect to the support wall to which the support rail 3 is attached, as shown in figure 12. This inclination allows aligning the above free passage of the retaining seat with the upper hooking portion 3b of the support rail 3, allowing such hooking portion 3b of the support rail 3 to fit all the way into the inner seat 11 formed in the free hooking end 7a of the hooking means 7.

[0050] In order to carry out the above hooking operation with rotation of the suspending device 101 with the upper hooking portion 3b of the support rail 3, it is first necessary to act on the longitudinal adjustment screw 5 so as to move the free hooking end 7a of the hooking means 7 away from the first side 10 of the support structure 4. This allows tilting the piece of furniture 2 with respect to the wall while avoiding interference between the piece of furniture 2 and the wall.

[0051] Once the cabinet suspending device 101 is in engagement with the hooking portion 3b of the support rail 3, acting on the longitudinal adjustment screw 5 causes a retraction of the free hooking end 7a of the hooking means 7 toward the first side 10 of the support structure 4, up to placing the back of the piece of furniture 2 at the correct distance from the wall, i.e. at the distance by which the back of the piece of furniture 2 touches wall 2 without being inclined anymore. In this configuration, the distance of the free hooking end 7a of the hooking means 7 from the first side 10 of the support structure 4 is such as to prevent the piece of furniture 2 from only assuming a rotated/tilted position by an angle much smaller than said angle α in figure 12, it being impossible to disengage the hooking portion 3b of the support rail 3 from the inner seat 11 formed in the free hooking end 7a of the hooking means 7, as can be seen in figures 14 and 15.

[0052] If it is necessary to remove the piece of furniture 2 from the wall, it is sufficient to act first on the longitudinal adjustment screw 5 so as to cause a distancing of the free hooking end 7a of the hooking means 7 from the first side 10 of the support structure 4, so as to again tilt the piece of furniture 2 by said angle α with respect to the wall (see figure 12).

[0053] As can be appreciated from what has been described, the cabinet suspending device according to the present invention meets the above need and overcomes the drawbacks which have been described in the introductory part of the present description with reference to the prior art. In fact, with a simple and easy to implement structure, the device is able to prevent the accidental disengagement of the cabinet suspending device attached to the cabinet from the support rail.

[0054] A further advantage of the cabinet suspending device according to the invention lies in that the same does not need further adjustment means with respect to those normally provided for adjusting the positioning in depth and the vertical positioning of the suspending device with respect to the support rail.

[0055] Of course, a man skilled in the art may make several changes and adjustments to the cabinet suspending device described above in order to meet specific and incidental needs, all falling within the scope of protection of the invention as defined in the following claims.

[0056] Thus, for example, reference is always made in the description to a support rail 3 as the use of support rails nowadays is the most widely used method of supporting cabinets on a wall. However, alternatively it is possible to provide for other support means to be attached to the wall that are structurally and/or functionally equivalent, such as hooks, brackets or pins.

[0057] Moreover, it is noted that, generally, for a correct support of a piece of furniture it is necessary to provide for the use of two or more suitably spaced apart cabinet suspending devices along the support rail.
