[0001] The present invention relates to a device for tilting and locking the resting surface
of a table.
[0002] In the catering sector, in bars or in reception rooms in general, tables are often
used which have tilting resting surfaces, which tilt from a horizontal configuration
for use to a vertical configuration for non-use, in order to facilitate the stacking
thereof when they are not needed.
[0003] Typically, such tables are provided with a central joint below the resting surface,
which connects a support of the surface, to which the latter is fixed, to the supporting
leg. In order to ensure that the horizontal configuration of the resting surface is
maintained, there is a snap-acting locking device with a moveable element that, pushed
by a spring, engages by snap action with the support of the resting surface, locking
it, and so also locking the resting surface which is integral therewith.
[0004] To unlock the resting surface, in so doing changing the configuration from horizontal
to vertical, the user must act on an adapted disengagement lever, which is positioned
at the locking device, in a position central to the resting surface and below it.
[0005] This solution, although widespread in the sector, is not devoid of drawbacks.
[0006] Access to the disengagement lever is not easy owing to its position, central to and
below the resting surface, forcing the user to bend down in order to reach the lever
and to exert thereupon the force required to release it.
[0007] Furthermore, the presence of the lever, which itself has a not inconsiderable size,
influences the weight and the cost of the tilting mechanism.
[0008] Also, these solutions are more easily adoptable for tables with a round resting surface,
than for tables with a rectangular resting surface, owing to the need to double the
mechanisms for locking and release (which must be installed on opposite sides), the
need to connect, on opposite sides, the actuation of the locking elements and of the
release levers, and owing to the need to connect the legs of the table to opposite
sides with a crosspiece, which, being typically thick and extending at the height
of the legs of the user, can interfere with them, without complying with the size
regulations now in force.
[0009] The aim of the present invention is to provide a device for tilting and locking the
resting surface of a table, for which the operations to release the resting surface
are easier than those needed with the solutions known nowadays.
[0010] Within this aim, an object of the invention is to provide a tilting device that is
easily adaptable to any type of table, either with central support or with a plurality
of supports and also with a rectangular resting surface, to comply with size regulations.
[0011] Another object of the invention is to provide a tilting device that is structurally
simple and easy to use, which can be implemented at low cost and the overall weight
of which is less than the solutions known nowadays.
[0012] This aim and these and other objects which will become better apparent hereinafter
are achieved by a device for tilting and locking the resting surface of a table, of
the type comprising at least one support for said resting surface, said device being
characterized in that it comprises:
- a body that is integral with said at least one support and extends along a tilting
axis below said resting surface and at least along much of the length of the latter,
to which it is also hinged at its ends,
- locking means, which comprise at least one tooth which protrudes from at least one
end of said body and is adapted to enter by snap action and reversibly a corresponding
opening at the edge of said resting surface when the latter is in the configuration
for use.
[0013] Further characteristics and advantages of the invention will become better apparent

[0014] With reference to the figures, the device according to the invention is generally
designated with the reference numeral 10.
[0015] The device designed for tilting and locking a resting surface 11 of a table 12, of
the type comprising at least one support 13, i.e. a single lower support centered
to the resting surface, as shown in the example of the table with a round resting
surface 11, or two lower supports, as in the example shown in Figure 5 for the table
12 with a rectangular resting surface 11.
[0016] The device 10 comprises a body 14 that is integral with the support, as can clearly
be seen in Figure 4, and which extends longitudinally along a tilting axis 15 below
the resting surface 11 and at least along much of the length of the latter, preferably
all of it as in the example to which it is also hinged at its ends (see Figure 5).
[0017] It also comprises locking means 16, which comprise at least one tooth 17 which protrudes
from at least one end of the body 14 and is adapted to enter by snap action and reversibly
a corresponding opening 18 at the edge 19 of the resting surface 11 when the latter
is in the configuration for use, typically horizontal.
[0018] In particular, a plate-like element 20, clearly visible in the enlargement in Figure
3, is joined, preferably by welding, to the edge 19 of the resting surface 11, on
the inside, and has the opening 18 within which the tooth 17 is adapted to engage.
There are conveniently two of such plate-like elements 20, in longitudinally opposing
positions, with which the body 14 is adapted to engage with its ends.
[0019] The resting surface 11 and the plate-like elements 20 are preferably made of metallic
material and the latter are obtained by blanking and bending sheet metal.
[0020] The locking means 16 comprise at least one element 21 for engagement with the edge
19 of the resting surface 11, in particular with the plate-like element 20. The engagement
element 21, indicated in Figures 6 to 9, has a square cross-section and has a free
end at which there is the tooth 17 and it is adapted to translate with respect to
the body 14, pushed by way of a spring 22, hereinafter referred to as the first spring
22, toward the outside of the body 14, so as to protrude therefrom with the tooth
17, as shown in Figure 8, and vice versa in opposition to the spring 22, as shown
in Figure 9.
[0021] The engagement element 21 is coupled with its end that lies opposite to the tooth
17 integrally with a translatable element 23, hereinafter referred to as the first
translatable element 23, within the body 14, which is tubular, along the direction
of extension of the latter.
[0022] The first translatable element 23 has a cavity 24 so as to correspond to a window
25 provided on the body 14, which, at least in the direction of translation of the
first translatable element 23, is longer than the cavity 24.
[0023] The device 10 can be provided with the engagement element 21, with the respective
first translatable element 23, at only one of the ends of the body 14, or, as in the
example shown, it can comprise a pair of opposite engagement elements 21, at the opposite
ends of the body 14, which are coupled so as to translate in opposite directions and
simultaneously, being connected by way of adapted transmission means 26.
[0024] Each one of them is integral with a respective first translatable element 23 and
is pushed by a respective spring 22 so as to protrude with the tooth 17 from the respective
end of the body 14.
[0025] The transmission means 26 comprise a linkage 27, at a first translatable element
23, which is pivoted in a central portion thereof on a rotation axis 28 which is perpendicular
to the direction of the tilting axis 15 and is coupled by the ends at, respectively,
the first translatable element 23 and a first end of a rod 29 which is integral with
the opposing first translatable element 23, which carries the other engagement element
21, to which it is coupled with an opposite second end.
[0026] The device 10 also comprises means 30 for the snap coupling of the body 14 to the
resting surface 11, which comprise a pair of cylindrical elements 31, which are aligned
along the tilting axis 15, each one at an end of the body 14, from which they protrude,
being pushed by way of a spring 32, hereinafter referred to as the second spring 32,
in order to be inserted by snap action in a corresponding circular hole 33 at the
edge 19 of the resting surface 11. The cylindrical elements 31 therefore constitute
the hinges with which the body 14 is coupled to the resting surface 11.
[0027] Each plate-like element 20 is conveniently provided with such a circular hole 33,
for receiving each one of the cylindrical elements 31.
[0028] Each cylindrical element 31 is integral with an element 34 which can translate within
the body 14, along the direction of extension of the latter, and which is provided
with a recess 35 at a slot 36 provided on the body 14 and along which the recess 35
is adapted to be translated with the translatable element 34. Hereinafter the latter
will be referred to as the second translatable element 34.
[0029] In particular, as can be seen from the exploded views, there are two caps 37 which
close each of the ends of the body 14.
[0030] From the view in Figure 7 and from the cross-section in Figure 10 it can be seen
that each one of the caps 37 has two openings from which the engagement element 21
can protrude and it has two receptacles 38 at each one of which a respective appendage
39, i.e. respectively of the first translatable element 23 and of the second translatable
element 34, is accommodated. The appendages 39 are hollow in order to accommodate
the respective springs, the first 22 and the second 32, which being helical are mounted
on a respective peg 40 of the appendage 39 and are contained between the inner wall
of the latter and a containment wall 41 of the receptacle 38, as can be seen from
Figure 10 (in which the device 10 is shown in cross-section taken along the tilting
axis 15).
[0031] In order to integrally associate the engagement elements 21 and the cylindrical elements
31 with the respective appendages 39, each one of the latter has, at the end, a channel
for inserting the end of the respective engagement element 21 or of the respective
cylindrical element 31, the latter conveniently having a groove.
[0032] Each cap 37 has a limb 42 extending toward the interior of the body 14, which is
interposed between a wall of the body 14 and the first translatable element 23 and
is conveniently provided with a through opening 43 with dimensions corresponding to
those of the window 25, which it overlaps.
[0033] For one cap 37, the one at the end portion of the body 14 in which the linkage 27
is present, there is a pin 44 on which the linkage 27 is hinged.
[0034] At the same portion, the first translatable element 23 is contoured to receive one
end of the linkage 27.
[0035] The body 14 is provided with holes 45 for the fixing of each of the caps 37, which
are conveniently perforated, by way of screws 46.
[0036] Each of the caps 37 has, on one of its sides, a recess 47 in which a filler 48 made
of elastically deformable plastic material, similar to rubber, is placed, which protrudes
from the end of the body 14 in order to abut against a respective portion 49 of the
plate-like element 20 (indicated in Figure 3) when the resting surface 11 is brought
to the configuration for use, the portion 49 being positioned below the resting surface
11.
[0037] Use of the device according to the invention is the following.
[0038] The resting surface 11 can be mounted on the support 13. It is positioned on the
body 14 with the plate-like elements 20 at the ends of the body 14. The tip of a screwdriver,
or other similar means, is inserted into one of the recesses 35 in order to shift
the second translatable element 34 toward the center of the body 14, thus making the
cylindrical element 31 retract into the body 14. The end of the body 14 is faced toward
the plate-like element 20 with the cylindrical element 31 at the circular hole 33.
[0039] The recess 35 is then released and the cylindrical element 31, pushed by the second
spring 32 toward the outside of the body 14, engages by snap action within the circular
hole 33.
[0040] The same operation is repeated for the opposite end of the body 14.
[0041] At the end of the mounting, the resting surface 11 will be tiltable about the tilting
axis 15, which passes through both of the cylindrical elements 31.
[0042] The locking of the resting surface 11 in the configuration for use occurs by inserting
the teeth 17 of the engagement elements 21 into the respective openings 18 of the
plate-like elements 20. This occurs by snap action, by way of the thrust of the springs
22, when the resting surface 11 is made to rotate into the configuration for use.
[0043] To return to the tilted configuration, the user acts directly with his/her hands
on one of the cavities 24 to make the first translatable element 23 slide within the
body 14, as shown in Figure 9.
[0044] In this step the opposing first translatable element 23 is entrained so as to translate
in the opposite direction from the previous one by way of the transmission means 26.
The linkage 27 rotates about the pin 44, causing the translation of the rod 29, which
entrains the opposing first translatable element 23. The two engagement elements 21
are then made to retreat into the body 14, in opposition to the thrust of the respective
first springs 22, thus releasing them from the engagement with the respective plate-like
elements 20.
[0045] In practice it has been found that the invention fully achieves the intended aim
and objects, by providing a device thanks to which the user can release the resting
surface of the table in order to bring it from a configuration for use to the tilted
position more easily and rapidly than the solutions nowadays known, independently
of the characteristics of the support of the resting surface and in compliance with
the size regulations in force.
[0046] In fact, the means to use in order to release the resting surface are positioned
at its perimeter and therefore are easily accessible, independently of the dimensions
and shape of the table.
[0047] Furthermore the device according to the invention is structurally simple and easy
to use, and is also lighter and more economic than the solutions known nowadays which
require the installation of a release lever.
[0048] Another advantage of the device according to the invention is that it enables the
user to easily mount and dismount the resting surface with respect to the supporting
structure, of which the tilting mechanism is substantially an integral part, and therefore
to not only stack more tables in smaller spaces but also to store the resting surfaces
and the supports separately. This possibility can also be convenient for transport.
[0049] The invention, thus conceived, is susceptible of numerous modifications and variations,
all of which are within the scope of the appended claims. Moreover, all the details
may be substituted by other, technically equivalent elements.
[0050] In practice the materials employed, provided they are compatible with the specific
use, and the contingent dimensions and shapes, may be any according to requirements
and to the state of the art.
