Description

REMOVABLE TABLE SYSTEM WITH MECHANISMS FOR FILLING AND

INTEGRATED FOLDING

[001] The invention relates to the field of folding / lifting tables, and more specifically a lift table system, advantageously equipped with an integrated automatic unfolding and folding system.

[002] For a long time, it has emerged the need to design foldable and foldable table systems, in order to both minimize the induced clutter and ensure the double-function of high table and coffee table. This need is particularly evident in large cities where the number of square meters of living space per person is reduced.

[003] In this context, many folding / liftable / convertible table systems have been developed. These folding table systems comprise means allowing them to move from a low position to a high position, and vice versa.

[004] Thus, the state of the art distinguishes three main categories of liftable tables:

table systems with "X" legs, with continuous raising and lowering movement;

- base table systems with pivot base with unfolding and manual folding;

table systems with vertical legs, with height adjustment using a jack or a screw system.

[005] Thus, by way of illustration of the state of the art, known collapsible and foldable tables generally comprise an adjustable "X" base. Other known folding and lifting tables have pivot-mounted legs. These legs mounted on pivots must be handled separately, resulting in an easy manipulation to move from a low position of the table to a high position of the table, and vice versa, since the manipulation must be performed in several times. [006] In general, a disadvantage of known foldable / liftable / convertible tables lies therefore in the relative complexity attached to their manipulation to move from a high position - or unfolded - to a low position - or folded - of these tables, and vice versa. Indeed, the folding tables / liftable / convertible known to move from their high position to their low position, and vice versa, usually requires several operations and / or the intervention of two people.

[007] In an attempt to overcome these known drawbacks, document US 4259909 A describes a table system comprising boomerang-shaped moving parts, rotatably mounted about pivots fixed on the underside of the table top, in the immediate vicinity of it. Said moving parts has a small side and a large side, on each side of each of the pivots, so that, by a rotation of the moving parts around the pivots, it is possible to put the table in a configuration of the coffee table type, in which the short sides of the moving parts are in contact with the ground, and the long sides are abutting against the underside of the table top, or in a high table configuration, in which the long sides of the moving parts are in contact with the ground, and the short sides are in abutment against the underside of the table top.

[008] A disadvantage of the folding / lifting table described in US 4259909 A lies in particular in the fact that the pivots around which the moving parts are rotating are placed in close proximity to the underside of the table top, so that it is not possible to implement boomerang-shaped moving parts, rotatably mounted on said pivots, or under a small-sized tray, with the risk that, when the table is in the coffee table configuration, the long sides form an unsightly and dangerous outgrowth, beyond the limits of said plateau, or under a plateau of very large size, the risk that the table configuration high table has a precarious balance.

[009] In addition, another disadvantage of this table system as described in US 4289909 lies in the fact that, as for other known folding / lifting table systems, it has no means of folding or automatic unfolding, so that it is necessary, to go from one configuration to another, to carry out several successive operations and / or to carry out these operations at least with the help of two people.

Thus, in summary, there is no known folding / lifting table system comprising an unfolding mechanism or folding integrated, allowing a only user to operate quickly, in a single manipulation, the transition from a coffee table configuration to a high table configuration, and conversely, the table system. Indeed, in the folding / lifting table systems of the state of the art, to perform the unfolding / folding of said table systems, in particular equipped with an articulated base system mounted on pivot, it is necessary to implement several steps and / or involve the intervention of two people.

[001 1] Other disadvantages of known systems reside in their inability to recover the irregularities of the ground, in their inability to withstand significant loads or in their instability. Thus, in order to overcome these unresolved disadvantages in the state of the art, there is a need for an optimized folding / lifting table system, incorporating automatic unfolding / folding means.

To this end, the foldable / foldable table system according to the present invention comprises a base system comprising pivoter-shaped mobile parts in the form of boomerang, and having integrated means of unfolding and folding automatic and instantaneous. In particular, the table system according to the invention comprises, for this purpose, a mechanism for rotating said boomerang-shaped moving parts in both directions synchronously.

To this end, more specifically, the present invention relates to a table system comprising a plate and at least two moving parts, preferably three moving parts, boomerang-shaped respectively mounted on a pivot adapted to a fixed connection piece on the underside of the tray, said at least two boomerang-shaped moving parts having, on one side of the pivot, a small side whose end opposite the pivot forms respectively a first point of support intended to be in contact with each other; with the ground and, on the other side of the pivot, a large side whose opposite end to the pivot forms respectively a second bearing point intended to be in contact with the ground, characterized in that the boomerang form of said at least two moving parts has an angle between the short side and the long side and respective lengths of said small and large sides adapted so that in a first position desdite s at least two moving parts about said pivot, said first and second bearing points are in contact with the ground, the table system then being in a low position, and in a second position of said at least two moving parts around said pivot, only said second fulcrum is in contact with the ground, and said first fulcrum is positioned, in abutment, under the lower face of the plate, the table system then being in a high position.

Furthermore, said table system is also remarkable in that it comprises a synchronized automatic unfolding mechanism to cause the synchronized rotation of said at least two moving parts around said pivot so that said table system switches from the low position at the high position and in that said table system comprises a synchronized automatic folding mechanism for causing the synchronized rotation of said at least two moving parts around said pivot so that said table system tilts from the up position in the low position.

According to a preferred embodiment, said connecting pieces have a shape adapted to deport said pivots at an offset distance under the lower face of the plate.

In this way, the table system according to the invention increases in compactness. According to one embodiment, the table system comprises at least three mobile parts boomerang respectively mounted on a pivot adapted to a connecting piece fixed on the underside of the plate.

According to one embodiment, the synchronized automatic unfolding mechanism and the synchronized automatic folding mechanism comprise a piston device, or a tensioner device, or a motorized device.

According to one embodiment, the synchronized automatic unfolding mechanism comprises a plurality of return springs, connected on the one hand to the connecting pieces, and on the other hand to the moving parts, said return springs being configured so that in the low position of the table system, said return springs are held in compression by the weight of the plate and so that, when the table system tray is at least partially supported, at least partially releasing said return springs from the weight of the plateau, said return springs are relaxed so as to cause the tilting of the moving parts around the pivots, until the first bearing points of said moving parts come against the stops. According to one embodiment, the synchronized automatic folding mechanism comprises a handle and a voltage cable network, said network of a tension cable being connected on the one hand to said handle and on the other hand to each of said return springs, and in that said handle and said tension cable network are configured in such a way that, while the table system is high position, by pulling action on the handle, the tension cable network is stretched and, the tabletop of the table system being at least partially carried in order to release the rotation of the moving parts around the pivots, the voltage of said network of tension cable causes the compression of the return springs, the compression of said return springs causing the rotation of the moving parts around the pivots, until the plateau ceases to be at least partially supported and the weight of said plate now compression springs in compression, the first and second support points, respective ends of the small and large side of each movable piece, are supported on the ground.

According to one embodiment, the table system according to the invention comprises three moving parts boomerang-shaped, so that the table system in the upper position rests on three points of support constituted by the second points of support, opposite ends to the pivots of the long sides of the moving parts, the first bearing points, ends opposite the pivots of the short sides of the moving parts abutting against the underside of the plate, and the table system in the down position rests on six points of support constituted by the first and second points of support, opposite ends to the pivots of the large and small sides of the moving parts. Advantageously, for illustrative purposes, the offset distance is 20 cm.

Advantageously, by way of illustration, the angle formed between the short side and the long side of the boomerang-shaped moving parts is 133 °.

Advantageously, for illustrative purposes, the small side of each mobile boomerang-shaped piece measures 24 cm, and that the long side of each mobile boomerang-shaped piece measures 52 cm.

Advantageously, by way of illustration, the plate has a circular shape with a diameter of 95 cm.

According to an advanced embodiment, the table system according to the invention further comprises a locking device of the table system in the upper position, to lock the table system in the up position, and / or a locking device of the table system in the down position, to lock the table system in the down position. Other features and advantages of the invention will appear on reading the detailed description of the embodiments of the invention, given by way of example only, and with reference to the drawing which shows:

FIG. 5, a bottom view of a table system according to the invention, shows a handle and a tension cable network providing the function of a synchronized folding mechanism;

FIGS. 6A and 6B, a schematic representation of an exemplary locking system of the table system in the high position.

In what follows, the described embodiments are more particularly related to a particular table system, wherein the synchronized folding mechanism and the synchronized unfolding mechanism are based on a handle, a plurality of springs of reminder and a voltage cable network. However, any implementation of a folding and unfoldable table system comprising a synchronized folding mechanism and a synchronized unfolding mechanism as provided by the present invention is also contemplated. With reference to the embodiment shown in particular in Figures 1A-1 B and 2A-2B, the table system according to the invention consists of a plate 1 on the lower surface of which are arranged a plurality of connecting pieces 2. At the lower end of these connecting pieces 2 is provided a pivot connection 4 around which each foot, consisting of a mobile part 3 boomerang-shaped, is rotatably mounted. As shown in Figure 3, the plurality of mobile parts 3 shaped boomerang are able to rotate around the pins 4 provided on the connecting pieces 2.

In addition, to optimize the compactness of the system, in the embodiment shown in all the figures, which is an advantageous embodiment but not exclusive, the connecting pieces 2 are adapted to ensure the offset pivots 4 at an offset distance under the plate 1 of the table.

3 boomerang-shaped moving parts have a small side and a long side, on each side of the pivot 4. [0034] Thus, by rotation around the pivots, the short sides and the long sides rest on the ground and the table system is then in a configuration "coffee table", the long sides rest on the ground, the short sides abut against the underside of the tray 1, and the table system is then in a configuration " high table ". In a preferred embodiment, as shown in Figures 1A-1B, 2A-2B and 5, the table system according to the invention comprises three sets comprising a mobile part 3 in the form of boomerang - a pivot 4 - a connecting piece 2.

Moving parts

As has been described above, the moving parts 3, forming the legs of the table system, are rotatably mounted around articulations arranged on the pivots 4, and have a boomerang shape with, on either side of the pivot, a big side and a small side. To ensure optimum mechanical rigidity, the small and large sides are preferably slightly bent, their curvature being oriented outwards. The dimensions of the short side, the long side, and the angle formed between said small and large sides of the boomerang-shaped moving parts are suitably configured so that, with reference to Figs. 1A-1B (low position), 2A -2B (up position) and 5 (bottom view:

- In the high position, the end opposite the pivot of the long side of each movable part 3 is in contact with the ground. The table is based on three points of support, and is therefore perfectly stable. The short sides of the moving parts 3 abut against the underside of the plate 1. - In the low position, each support point is split, on either side of the pivot 4, since the ends opposite the pivot 4 of the small and large side of each movable part 3 is in contact with the ground. The table then rests on six points of self-stable supports, conferring on the whole a particularly high stability, coupled with an increased capacity to support a load deposited on the plate 1 as well as an ability to catch the irregularities of the ground , because of the possibility for each movable part 3 to benefit from a degree of freedom in rotation around the pivot 4.

The table system according to the invention further comprises automatic unfolding and folding means.

Indeed, the table system has a lifting / unfolding system and lowering / folding mechanically assisted. To achieve this function, the table system according to the invention takes advantage of the fact that the plurality of connecting pieces 2 cooperate with a set of independent joints, consisting of the plurality of pivots 4 arranged on said connecting pieces 2, they they are also fixed on the underside of the tray 1 of the table.

Thus, with reference to the embodiment shown in Figure 4, the articulation between each movable part 3 and the corresponding connecting piece 2 is formed by a pivot link 4 independent, with a return spring 8, connected d 1 part to the frame of the joint that constitutes the connecting piece 2 and secondly to the moving part 3, said return spring 8 being able to cause the rotation of the movable part 3 around the pivot 4 in both meaning, as it relaxes or compresses. In addition, the return spring 8 is connected to a voltage cable network 10, actuable by the handle 1 1 (or by any equivalent means for transmitting the movement) to force the compression of said return spring 8 by pulling on said handle 1 1.

The table system according to the invention comprises at least two moving parts boomerang-shaped, and preferably three. According to a preferred embodiment, the table system according to the invention comprises three moving parts boomerang-shaped ensuring the function of legs of the table system. According to other embodiments, a table system according to the present invention may comprise four or even more legs. The specific shape of the moving parts 3, as shown in FIG. 3, said specific form being linked in particular to their boomerang shape, to the dimensions of the small and large sides, to the angle formed between the small and the large side thus, if any, that the respective curvature of the small and large sides, is expected to have different advantages explained below, depending on the selected embodiments.

In the upper position of the table system according to the invention, the short sides of the moving parts 3 abut against the underside of the plate 1. The stop 5 of each movable part 3 pivoting is very far from the pivot axis 4, so that the functional blocking games are reduced. In addition, since the stops 5 are remote from the pivot connection 4, the support lever arm is very important, so that the table system is able to withstand high loads, without the risk of damaging said stops 5.

In the low position, each movable part 3 ensures two points of support on the ground, taking advantage of their shape boomerang. In this low position, the slight rotation allowed by the pivot connection makes it possible to catch the irregularities of the ground and ensures perfect positioning of the table system according to the invention.

The pivot connection

Referring to Figure 4, according to a particular embodiment, each pivot 4 is independent and is arranged on the connecting piece 2, which forms the frame of the pivot connection. The mobile part 3, boomerang-shaped, is rotatably mounted about the axis 6 of the pivot 4, in pivot connection relative to the connecting piece 2, by means of two bearings 7. The axis 6 of the pivot 4 is further connected to a return spring 8 which is itself connected to the moving part 3. This return spring 8 allows the tilting of the boomerang-shaped moving parts 3 around the pivot 4 of axis 6. By this rotation, the table system goes up when raising the plate 1 of the table under the effect of the expansion of the return spring 8. According to this embodiment, the axis 6 of the pivot 4 is also fixed to a connecting rod 9, itself connected to a network of tension cable 10 attached to a handle 1 1.

The operation of the table system

Advantageously, by the implementation of the table system according to the invention, with its automatic unfolding and folding means, the lifting / unfolding, as the lowering / folding of the table has an immediate character. The manipulation to switch the table system according to the invention from a high position to a low position, and vice versa, is achievable in a single operation.

The lifting / unfolding

Still in reference to FIG. 4, according to a preferred embodiment, the return springs 8, at the joints formed by the pivots 4, are compressed in the low position and are maintained in this compressed state due to the weight of the plate 1 of FIG. Table. For the user, it is sufficient to lift the plate 1, so that said plate 1 is at a height of the ground greater than the total height of the moving parts 3, so that the return springs 8, released from the weight of said plate 1, relax and exert a force on the pivots 4 causing the rotation of each of the moving parts 3 around said pivots 4, so that first bearing points, ends of the short sides of the moving parts, abut against the stops 5 on the lower face of the plate 1, and second support points, ends of the long sides of said moving parts 3, are in contact with the ground when the user rests the table, the table system then being in high position. The table switches automatically and instantly to the up position. It should also be noted that, according to this embodiment, in which the return springs 8 are held in compression by the weight of the plate 1, the automatic unfolding of the table remains functional even if the plate 1 is not raised. flat, thanks to the mechanical assistance produced by the return springs 8.

[0046] Lowering / folding

Referring to Figures 4 and 5, according to a preferred embodiment, to lower the table, the user activates the handle 1 1, pulling on it, so as to pull the voltage cable network 10 so that said network of tension cable 10 causes the compression of the return springs 8, while the user slightly raises the plate 1 to allow the rotation of the moving parts 3 around the pivots 4. Thus, the return springs 8 compress while rotating the moving parts 3 in the form of a boomerang around the pivots 4 of axis 6, so that the table system switches to coffee table configuration, the opposite ends to the pivot 4 of the long sides of the moving parts 3 coming into contact with the ground and the opposite ends to the pivot 4 of the short sides of the moving parts 3 abutting against the underside of the plate 1. Once the rotation of the moving parts 3 performed, the user is indeed in effect the plateau 1 with the weight ensures the maintenance of the springs 8 in compression. The shape of the plate 1 of the table and its weight are also preferably provided to allow such a manipulation is easily achievable.

Furthermore, the voltage cable network 10 and the return springs 8 are arranged so that the mechanical assistance they confer is synchronized, so that the unfolding as folding are synchronous, in the sense where the triggering of the tilting of all moving parts 3 is performed simultaneously. Thus, the moving parts 3 are engaged simultaneously in the rotation that sees them move from their unfolded position to their folded position, and vice versa, without this meaning that said moving parts 3 are at all times at the same stage of their unfolding or their folding. The synchronization of unfolding and folding therefore means that said unfolding or folding takes place in parallel for all moving parts 3.

[0048] Sizing example:

By way of illustration, a table system according to the invention may have the dimensions listed below. It goes without saying that these dimensions are given by way of example and that a person skilled in the art is able to produce a table system according to the present invention and having different dimensions, subject to respecting the technical constraints and specifications. proportions described herein.

Thus, in an exemplary embodiment of the table system according to the invention:

- the offset distance is 20 cm;

the angle formed between the short side and the long side of the boomerang-shaped moving parts is 133 °,

the small side of each mobile boomerang piece measures 24 cm, and the long side of each mobile boomerang piece measures 52 cm, the tray has a circular shape with a diameter of 95 cm.

The locking device of the table system in high or low position

According to an advanced embodiment, the table system according to the invention further comprises a locking device in the high position and / or a locking device in the low position. With reference to FIGS. 6A and 6B, there is described an exemplary device for locking the table system in the high position, to lock the table in the up position after unfolding. According to this particular embodiment, again with reference to FIGS. 6A and 6B, each foot, that is to say each moving part 3, is locked under the plate 1 by means of a retractable pin 15. This retractable pin 15 is able to slide in an axial guide 12 arranged in the fixed part of the base, namely the connecting piece 2, or in its moving part, namely in the moving part 3. When the moving part 3 rotates around the 4 pivot connection to allow the unfolding of the table system, the retractable pin 15 slides in the axial guide 12 and is housed in a corresponding cavity arranged directly in the movable part 3 or, as shown, in a receiving part 13 provided for this Indeed, in order to limit the wear of the moving part 3. The retractable pin 15 is thus able to translate in the axial guide 12 and can be actuated mechanically, automatically or manually. The locking and unlocking of the retractable pin 15 may further be actuated by a spring, cable, or other equivalent means. The fastener 14 of the retractable pin 15 serves to maintain the retractable pin 15.

In summary, the table system according to the invention has the advantage of being "transformable", in the sense that it can be used in the low or high position, the transition from the low position to the high position, and reciprocally, being achievable by a single person, in a single simple operation, thanks to the specific means described above conferring a mechanical assistance to the unfolding and the synchronized folding of the system.

Such a table system, according to the present invention, is in the form of a plate 1 with movable parts 3 mounted on pivots 4 arranged on connecting pieces 2 fixed on the underside of the plate 1 , said connecting pieces 2 preferably ensuring an offset of said pivots 4 at a distance from said plate 1.

It is specified, moreover, that the present invention is not limited to the preferred embodiment described in detail above and is capable of numerous variants accessible to those skilled in the art.

In particular, it should be noted that the embodiments of the mechanical assistance means for allowing the synchronized rotation of the moving parts 3 around the pivots 4 comprise a plurality of return springs 8 and a voltage cable network 10 However, the springs 8 and the cable 10 may be replaced by any equivalent means for exerting a torque on said parts 3, via, for example, a piston device, a tensioner device, or a motorized device.

Similarly, the particular embodiment described, having the synchronized automatic unfolding / folding mechanism as constituted by a plurality of springs cooperating with a cable network and a handle, can quite be mounted in an inverted manner, in the sense that the springs are then compressed in the upper position of the table system, and released in the low position.

Other variants can be imagined by those skilled in the art implementing the present invention.
