[0001] Wall attachment for furniture, characterized in that it comprises a set of parts
which when operatively mounted provide a flat assembly of thickness conveniently less
than the width of a mortise (6) made vertically in the rear edge of the side panels
(5) of a piece of furniture, and which with its ogival lever (4) forms a disc (19)
which through rotary adjustment is housed in a housing (27) having a resilient perimeter
formed in a resilient plate (26) fitted on the hook (2) in such a way that it is housed
between the body of the hook (2) and the wall of the said mortise (6) opposite that
in which the said base (1) is located, this disc (19) having peripheral teeth (28)
matching four toothed segments (29) formed in the housing (27).
SCOPE OF THE INVENTION
[0002] This invention relates to a fitting for the attachment of furniture to a wall having
the capability for adjustment in height, frontal inclination and of course laterally.
PRIOR ART
[0003] A great variety of devices for the attachment of furniture to walls are known in
the field to which this invention relates.
[0004] Basic requirements for these devices are that they should be hidden from view but
that they should nevertheless be reasonably accessible for making those adjustments
through which the piece of furniture can be suitably aligned as part of a set of furniture
or with respect to its surroundings, once the piece of furniture has been positioned
in its installed location.
[0005] The need to associate these conditions with the provision of mechanisms giving rise
to the adjustments indicated and with the limitations on location imposed by the design
of the furniture itself and its relationship to other pieces of furniture abutting
it which have to be adjusted in the same way all have the effect that known arrangements
are of complex construction and complex to install, and have to be accessed through
openings made in the back of the furniture so that adjustments can be carried out
when the pieces of furniture are alongside each other. In such circumstances, for
the purposes of hiding from view and installation it is necessary to take advantage
of the fact that the back of the furniture is recessed, creating a space between it
and the wall in which it is necessary to work in order to fit the attachment and support
it on the sides and top of the piece of furniture (the back being generally weak for
this purpose) through a fitting operation which is laborious and difficult to mechanize.
When the back of the furniture is flush fitted the attachment has to be fitted within
the piece of furniture leaving only the hook which attaches to the wall-mounted anchorage
projecting behind (through the back).
EXPLANATION OF THE INVENTION AND ITS ADVANTAGES
[0006] This being the case, this invention provides a wall attachment for furniture comprising
a set of parts which when operatively fitted forms a flat assembly of a thickness
which is conveniently less than the width of a mortise which is made vertically in
the rear edge of the side panels of a piece of furniture having a height and depth
which are requisitely greater than the corresponding heights and widths of a said
set of parts comprising a base, a hook, a spiral rotary lever for vertical adjustment,
or a spiral lever and an ogival rotatory lever for frontal adjustment, or an ogival
lever, in which the base lies against one side of the mortise and is screwed to the
bottom thereof, the hook has a tip which is capable of engaging a hook support anchored
to the wall to which the piece of furniture is attached, the spiral lever has its
spiral perimeter supported on a lateral projection of the hook and rotates supported
against the upper extremity of a vertical opening formed in the base, in which both
the spiral lever itself and the lateral projection can be slidably adjusted, the ogival
lever rotating and being supported on a lower bearing which is formed in the base
and is provided with sliding rotary adjustment between the vertical edges of a groove
which is formed in the said hook, while this ogival lever forms a disc which through
rotary adjustment is housed in a resilient peripheral housing formed in a resilient
plate which is installed in the hook in such a way that it is enclosed between the
body of the hook and the wall of the said mortise opposite the same against which
the said base abuts, the said disc having a toothed perimeter which matches four toothed
segments formed in the said housing with radial members which are placed between each
of the adjacent toothed segments, the spiral and ogival levers of which being each
provided with first recesses for the application of a rotary activating tool, which
are accessible through openings in the wall of the mortise corresponding to the interior
of the piece of furniture.
[0007] This proposed arrangement has the virtue that it is installed embedded within the
thickness of the side panels of the piece of furniture, thus at the same time solving
many problems such as: hiding it perfectly from view, in which only the tip of the
hook projects by the amount strictly necessary for attachment to the hook support
anchored to the wall, with the result that, once the piece of furniture is mounted
on the wall, all of it is wholly hidden from view; simple installation capable of
simple mechanization through screwing to the base of the mortise; accessible and sensitive
manoeuvrability through simple holes made in the inner wall of the mortise, providing
the possibility of convenient independent adjustment of pieces of furniture abutting
each other laterally; release of space within the piece of furniture for its essential
purpose; application to pieces of furniture with both a flush or recessed back; applicability
to both the right- or left-hand side panels of the piece of furniture, given that
the said spiral lever and ogival lever are each provided with second recesses for
the application of a rotary activating tool.
[0008] These and other particulars of the invention are detailed in the appended graphical
illustration.

DESCRIPTION OF A PREFERRED EMBODIMENT
[0011] A preferred embodiment of the wall attachment according to the invention is described
in the appended drawings in relation to the drawings and references listed above.
[0012] As shown in Figure 1, this attachment is embedded in the thickness of the side panel
(5) of the piece of furniture and comprises a set of pieces which when operatively
fitted offer a flat assembly of a thickness which is conveniently less than the width
of a mortise (6) made vertically in the rear edges of the side panels (5) of a piece
of furniture having a height and depth which are duly greater than the corresponding
heights and widths of said set of parts comprising a base (1), a hook (2), a rotatory
spiral lever for vertical adjustment, or a spiral lever (3) and an ogival rotatory
lever for frontal adjustment, or ogival lever (4), in which the said base (1) abuts
one side of the mortise (6) and is screwed to the base thereof, the said hook (2)
has a tip (7) which can be engaged by a hook support (8) attached to the wall (9)
to which the furniture is attached, the said spiral lever (3) has its spiral perimeter
bearing against a lateral projection (10) of the said hook (2) and rotating supported
against the upper extremity of a vertical space (11) formed in the said base (1) and
which is slidably adjusted at the appropriate time, the said ogival lever (4) rotating
supported on a lower bearing (12) formed in the said base (1) and provided with rotary
and sliding adjustment between the vertical sides (14) of a groove (13) formed in
the said hook (2), while the said ogival lever (4) forms a disc (19) which is housed
with rotary adjustment within a housing (27) having a resilient perimeter which is
formed in a resilient plate (26) fitted in the hook (2) in such a way that it is enclosed
between the body of the hook (2) and the wall of the said mortise (6) opposite thereto
against which the said base (1) abuts, the said disc (19) having a toothed perimeter
(28) matching four toothed segments (29) formed in the said housing (27) with radial
members (30) fitted between each of the two adjacent toothed segments (29), these
spiral (3) and ogival (4) levers being each provided with first recesses (15, 16)
for the application of a rotary activating tool (22) which can be accessed through
openings (23) in the wall of the said mortise (6) on the interior of the piece of
furniture.
[0013] Operative fitting of the attachment in the mortise (6) only requires the securing
screws (24) to be screwed to the bottom of the said mortise (6), as a result of which
the tip (7) of the hook (2) is located at a specific point to facilitate attachment
to the hook support (8) anchored to the wall (9) and with respect to which the lateral
position of the piece of furniture may be adjusted.
[0014] Once this has been fitted, the first recesses (15, 16) respectively of spiral (3)
and ogival (4) levers are opposite the holes (23) provided for access and activation
by the tip of rotary activating tool (22); obviously individual openings (23) may
be converted into a single window covering the two. At this point it is worthwhile
pointing out that one feature of the invention lies in the fact that these spiral
(3) and ogival (4) levers are each provided with second recesses (20, 21) for the
application of a rotary activating tool (22); this means that the attachment may be
fitted to either of the left- or right-hand side panels (5) of the piece of furniture,
with the sole difference that in one case activation by the tool (22) takes place
on the said first recesses (15, 16) or the second recesses (20, 21).
[0015] Consideration of this assembly (Figures 1 and 2) together with the constituent details
of the individual parts (Figures 3 to 13) will provide a rapid understanding of an
operation which is in any event quite simple.
[0016] In order to adjust for height, it is necessary to rotate spiral lever (3) (in an
anticlockwise direction in Figure 2) from the position in that Figure 2, and the piece
of furniture will rise progressively until this spiral lever (3) bears against lateral
projection (10) of hook (2) and against the upper extremity of the space (11) in base
(1), a movement which continues until the time when the tip (25) of spiral lever (3)
abuts against lateral projection (10).
[0017] The fact that the said spiral lever (3) has its active edge provided with parallel
knurling (18) which in order to keep the adjusted position firm is matched by a rib
(34) cut into the said lateral projection (10) of base (1) of the attachment and on
the other hand the fact that this spiral lever (3) forms a prominence (Figures 8 and
9) which projects laterally against the body of the said base (1), a prominence which
exerts an extra transverse pressure on the body of the spiral lever (3), helps to
maintain the adjusted position. Furthermore, adjustment of spiral lever (3) in base
(1) prevents oscillations from occurring in its plane, assisted to some extent by
the fact that its flat active body is enclosed with rotary adjustment between the
bodies of base (1) and hook (2).
[0018] In order to adjust the frontal inclination of the piece of furniture, it is sufficient
to rotate ogival lever (4) so that one or the other of its symmetrical edges (depending
upon which of the side panels of the piece of furniture is involved) presses against
the corresponding vertical side (14) of groove (13) of hook (2) and through reaction,
by rotating on bearing (12) of base (1), gives rise to tipping of hook (2) and this
tipping has the result that the piece of furniture is adjusted frontally. In this
rotary manoeuvre of ogival lever (4) a resilient offset in the form of a ratchet is
produced between the toothed periphery (28) of disc (19) and the toothed segments
(29) of resilient plate (26), this being made possible through the resilient nature
of resilient plate (26) itself and the existence of the radial members (30) placed
between these toothed segments (29); once the adjustment action is complete, the resilient
plate recovers its initial condition and gives rise to coupling between toothed periphery
(28) and toothed segments (29), which, also assisted by the inherent weight of the
attached piece of furniture, firmly secures the point of adjustment established and
provides fine adjustment within the possible range of adjustment.
[0019] Stability against tipping in its plane of rotation is in this case ensured through
adjustment of ogival lever (4) in lower bearing (12) of base (1), and this is helped
to some extent through the existence of its disc (19) which is enclosed within the
body of said hook (2) and the wall of said mortise (6) opposite thereto against which
said base (1) abuts.
