SCOPE OF THE INVENTION
[0001] The present invention relates to a lower levelling support element for overhanging
wall-mounted furniture that is intended to complement the upper support element of
the furniture and to counteract the tipping moment of the furniture. The invention
also enables access beneath the furniture for the purpose of adjustment.
PRIOR ART
[0002] In this field, lower feet located at the base of the furniture that support said
furniture in conjunction with the upper support element to offset the tipping moment
of the furniture are known.
[0003] Numerous support elements are known that are relatively complex, in relation to the
subject matter of the present invention, in that a large number of elements are used
to form the device itself, the construction of which requires complicated production
processes. For this type of device, the back of the furniture needs to be machined,
as there is no other way to access the support element. Furthermore, the complexity
of the support element means that the parts are not symmetrical and therefore a special
part has to be created for each side, the right-hand side and the left-hand side.
This has a negative impact on production costs and subsequent assembly by specialized
labour.
[0004] Moreover, for longer furniture, this system provides no guarantees against bowing,
as the aforementioned device can only be installed at the sides of the furniture,
and it is impossible to install it halfway along the length of the furniture in order
to prevent bowing. This limits the length of the furniture that can be worked with.
DESCRIPTION OF THE INVENTION AND ADVANTAGES
[0005] In consideration of the prior art, the subject matter of this invention is a lower
levelling support element for overhanging wall-mounted furniture anchored to the wall
with, made up of metal-injection-moulded parts having outstanding elasticity, mechanical
strength, hardness and machinability properties, which, for each side of the furniture,
include an anchoring plate and an adjustable support foot with a support surface for
the structural side panels and/or base panels of the furniture, there being beneath
said support surface an adjustment zone with the vertical-adjustment screw head and
the depth-adjustment screw head, which are directly accessible beneath the furniture.
[0006] The vertical-adjustment screw head has a vertical-adjustment shaft, the end of which
is fitted with a ring gear that meshes with the pinion gear of a threaded rod and
the opposite end of which has a stop for the threaded rod joined to the anchoring
plate through the stop window, said threaded rod being provided with a coupling nut
to the anchoring plate, in the movement of the slider with the slider guide thereof
in the plate guide, the guide of the slider fitting the guide of the anchoring plate.
[0007] The stop ensures that the pinion gear of the threaded rod does not bear all of the
force and the tipping moment.
[0008] The coupling nut is coupled to the anchoring plate through windows in said anchoring
plate, the height of the sides of the window being the same as the coupling nut.
[0009] The depth-adjustment screw of the depth-adjustment screw head is attached to the
projection of the guider of the horizontal portion of the adjustable support foot
that is guided on the guider channel of the adjustable support foot, said guider having
a wall that can butt against the base panel of the furniture.
[0010] The support surface of the adjustable support foot is U-shaped, which facilitates
reception of the side panel and/or base panel of any of the sides of the furniture.
[0011] Vertical adjustment helps to position the furniture horizontally when installed overhanging
on a wall. To achieve this using a rotary actuating tool, access is provided to the
shaft fitted with the ring gear that meshes with the pinion gear of the threaded rod
that is located vertically, all of which without interfering at any time with the
furniture.
[0012] The diameter of the horizontal-adjustment screw matches the thread of the guider
projection, the width of said guider projection fitting the guider channel of the
adjustable support foot.
[0013] Another noteworthy feature of the invention is that the lower levelling support element
is symmetrical, i.e. it is neither left- nor right-sided, which helps to significantly
reduce both manufacturing and assembly costs.
[0014] Furthermore, there is a risk of bowing when installing longer furniture. In this
case, the lower levelling support element proposed can be installed halfway between
the side panels of the furniture, thereby avoiding the aforementioned problem, as
the furniture need not be machined in any way to install the lower levelling support
element.
[0015] The support surface of the adjustable support foot of the lower levelling support
element is U-shaped, which helps to hold any of the side panels and/or base panels
of the furniture.
[0016] Moreover, it is noteworthy that the inside of the furniture need not be machined
in an y way for installation on the lower levelling support element, as the furniture
is supported on it and the vertical adjustment and the depth adjustment can both be
accessed from underneath the furniture, for which the vertical-adjustment and depth-adjustment
screw heads are provided with a frontal configuration for the tip of a rotary actuating
tool.
[0017] All of the foregoing provides the following advantages: injection-moulded production,
which is cheap for mass production and the automation of which is common and uses
conventional means, and easy automation of assembly of the unit itself.
[0018] These and other details of the invention are explained in the detailed description
below, which is based on the attached figures.

PREFERRED EMBODIMENT
[0021] With reference to the drawings and references mentioned above, the attached views
show a preferred embodiment of the subject matter of the invention, which relates
to a lower levelling support element (1) for overhanging, wall-mounted furniture (18)
that is anchored to the wall (20), which includes an anchoring plate (16) and an adjustable
support foot (2) with a support surface (3) for the structural side panels (21) and/or
base panels (22) of the furniture (18), there being beneath said support surface (3)
an adjustment zone (4) with the vertical-adjustment screw head (11) and the depth-adjustment
screw head (8a), which are both directly accessible beneath the furniture (18).
[0022] The vertical-adjustment screw head (11) has a vertical-adjustment shaft (12), the
end of which is fitted with a ring gear (13) that meshes with the pinion gear (14a)
of a threaded rod (14), said threaded rod (14) being provided with a coupling nut
(15) to the anchoring plate (16) through the window (16b), in the movement of the
slider (17) with the slider guide (17a) thereof in the plate guide (16a).
[0023] The depth-adjustment screw (8) of the depth-adjustment screw head (8a) is attached
to the projection (7) of the guider (6), which is guided along the guider channel
(5) of the adjustable support foot (2); said guider (6) having a front wall (10) that
can butt against the base panel (22) of the furniture (18).
[0024] The invention provides for the overhanging furniture (18) to be supported on at least
two lower levelling support elements (1), which are located on the side panels (21)
of the furniture (18). The support surface (3) of the adjustable support foot (2)
is U-shaped, which facilitates reception of the side panel (21) and/or base panel
(22) of any of the sides of the furniture (18).
[0025] Another noteworthy feature of the invention is that the lower levelling support element
(1) is symmetrical, i.e. it is neither left- nor right-sided, which helps to significantly
reduce both manufacturing and assembly costs. Furthermore, there is a risk of bowing
when installing longer furniture (18). In this case, the lower levelling support element
(1) proposed can be installed halfway between the side panels (21) of the furniture
(18), thereby avoiding the aforementioned problem, as the furniture (18) need not
be machined in any way to install the lower levelling support element (1).
[0026] The end of the threaded rod (14) opposite the pinion gear (14a) has a stop (25) for
the threaded rod (14) connected to the anchoring plate (16) through the window (16d)
of the anchoring plate (16).
[0027] The simplicity of construction and assembly is evident from the exploded view in
Figure 4, which clearly shows that the lower levelling support element (1) is built
using simple and rapid component assembly operations, without the need for other linking
or fastening means, which facilitates and reduces the cost of manufacture and assembly.
The assembly sequence is illustrated in Figure 4, in which the arrow (26) indicates
the assembly position for the stop (25) for the threaded rod (14). Said stop (25)
helps to ensure that the pinion gear (14a) of the threaded rod (14) does not bear
all of the force and the moment generated by the weight of the furniture (18) when
it is installed on the wall (20).
[0028] Figures 6 and 7, using the cross sections A-A' and B-B' indicated in Figure 5, illustrate
the depth adjustment and vertical adjustment respectively.
[0029] Vertical and depth adjustment are clearly shown in Figures 6 and 7. Depth adjustment
(Figure 6), which establishes a series of relative positions between the wall (20)
and the side panel (21) and the base panel (22) of the furniture (18), is effected
by turning the depth-adjustment screw head (8a) in either direction using a rotary
actuator tool (24), without interfering with the furniture (18). To do so, the depth-adjustment
screw (8) is connected to the projection (7), which results in a horizontal movement
of the guider (6) along the guider channel (5) of the adjustable support foot (2);
the base panel (22) of the furniture (18) bears against the front wall (10) of the
guider (6), and consequently the successive positions thereof result in tilting of
th e furniture (18) in one direction or the other, thereby adjusting the depth.
[0030] Vertical adjustment (Figure 7) is achieved by rotating in either direction, using
a rotary actuating tool (24) and without interfering with the furniture (18), the
vertical-adjustment screw head (11) comprising a vertical-adjustment shaft (12), the
end of which is fitted with a ring gear (13), that meshes with the pinion gear (14a)
of the threaded rod (14), which is provided with a coupling nut (15) to the anchoring
plate (16).
[0031] The foregoing results in a vertical movement of the threaded rod (14) that, on account
of the coupling of the coupling nut (15) to the anchoring plate (16), transforms the
movement of the vertical-adjustment screw head (11) into movement of the slider (17)
of the adjustable support foot (2) along the guides (16a) of the anchoring plate (16)
in conjunction with the guides (17a) of the slider (17).
[0032] Thus, the movement causes a vertical movement of the adjustable support foot (2)
as shown in Figure 7, where the structural side panel (21) and/or base panel (22)
of the furniture (18) are butted together.
[0033] T h i s detailed description demonstrates the aforementioned simplicity of the design
provided, as well as the functional reliability and efficiency thereof, th e capacity
fo r final self-adjustment thereof, and the absence of mechanical connections likely
to cause faults, require maintenance work or suffer mechanical degradation over time;
as well as the reversibility thereof, which permits assembly on either of the side
panels (21) of the furniture (18) indistinctly.
