Description

MODULAR SUPPORT DEVICE IN DIMENSIONS

FIELD OF THE INVENTION

The present invention relates to support devices with light trays allowing a user to easily deploy a support in a desired location, which is therefore in particular easy to move and store.
BACKGROUND OF THE INVENTION

The present invention aims to constitute such a device which also allows adaptation of the available support surface, in particular by doubling it to integrate an additional user.

PRIOR ART

Extensible tables are known which make it possible to carry out a multiplication of the available support surface. Referring to utility certificates CN206548101 and CN206261144, this type of table with extensions on legs and/or trestles, designed for many guests (generally at least four) are unsuitable for deployment in certain restricted spaces, in particular on beds to have breakfast in bed with a limited number of people.

Furthermore, it is known to produce trays comprising adjustable functionalities. For example, the utility certificate CN206576537U describes a tray with adjustable legs in inclination so as to have a tray, on his bed or on a table, which makes it possible to accommodate and orient in inclination a laptop computer.

This solution is nevertheless unsuitable for adjusting the surface of the available platform. In addition, patent application GB2545182 A describes a device whose periphery is adjustable, offering an extendable frame with four adjustable screws which delimits an outline without full support: a support must be placed on this frame, for example a board.

Thus, none of the currently known devices integrates a modularity of dimension of a support integrated into a tray suitable for restricted spaces, in particular to constitute a coffee table or a breakfast tray in bed.

The need to overcome the problems encountered on existing devices led to the present invention.

The object of the invention is to overcome at least some of the aforementioned drawbacks and to propose a support device serving in particular as a tray and capable of combining the advantages of speed, simplicity and modularity for its implementation.

In view of the foregoing, the subject of the invention is a light support device comprising a main support and two lateral legs provided at two opposite ends of said main support, comprising an auxiliary support linked to said main support and means for deploying said auxiliary support between a retracted position of said auxiliary support relative to said main support and an extended position of said auxiliary support relative to said main support.

Preferably, the side legs are retractable under the main support and/or under the auxiliary support and mounted on pivoting hinges.

For example, the main support is hollowed out to accommodate said rotating side feet so that they are either retracted into a receiving housing thereof, or flush with respect to a lower surface thereof.

Advantageously, the auxiliary support is pivotally mounted thanks to the deployment means.

According to one embodiment, the auxiliary support is mounted in linear connection on the main support thanks to deployment means which constitute means for guiding in translation of one relative to the other.

In one embodiment, the means for guiding in translation comprise a male element on one of the main support and of the auxiliary support and a complementary female element of said male element on the other of the main support and of the auxiliary support.

Advantageously, the male and female elements are assembled in a dovetail.

The method may further comprise the female element comprises a sliding rail.

Preferably, a mechanical bearing transforming into sliding or rolling the translational friction due to the transition from the retracted and deployed positions.

The invention also relates to a method in which at least one removable host structure in or on one of the main and auxiliary supports.

DETAILED DESCRIPTION OF FIGURES

Figure 1 illustrates a front view of the device 1 used to constitute a light support of modular size.

In the first illustrated embodiment, the device 1 comprises for this purpose, in the manner of known breakfast trays, a main support 3 and two lateral legs 5 provided at two opposite ends of said main support 3.

Such a device is generally made of plastic, for example by thermoforming, to increase its lightness. The device 1 can be made with materials allowing an optimal combination of mechanical strength and lightness, while benefiting from a texture and surface appearance suitable for proximity use, for example wood.

The side legs 5 are, in a known manner, retractable under the main support 3 and/or under the auxiliary support 7 and mounted on pivoting hinges 4.

The main support 3 can be hollowed out to accommodate the rotary side feet 5 so that these can be retracted into a housing 10 for receiving the latter 3, or else flush with a lower surface thereof. ci 3. The housing 10 is for example provided under the main plate 3 or on its sides, as illustrated in Figure 3.

In addition, the device 1 comprises an auxiliary support 7 linked to said main support 3. The auxiliary support 7 or extension 7 makes it possible to extend the sole surface of the main plate 3.

For this, the device 1 comprises deployment means 8,9 of said auxiliary support 7 between a retracted position, in which the auxiliary support 7 is retracted relative to said main support 3, and a deployed position in which said auxiliary support 7 is deployed. relative to said main support 3.

In the first embodiment illustrated by Figure 1, the device 1 can further comprise at least one auxiliary foot 6, which can also be removably or retractably mounted in one of the plates 3, 7. The foot 6 can be, as desired, , disposed either on the main support 3 (as in Figure 1 for the first embodiment), or on the auxiliary support 7 (as in Figure 2 for the second embodiment).

Thus, the legs 5 and 6 are interchangeable in design, having equivalent functions of substantially horizontal maintenance of the main 3 and auxiliary 7 supports.

These feet 5, 6 can be in the form of bars, tubes or arches, as illustrated by way of example and not limiting. They can also have known additional functions, such as tilt adjustments, non-slip pads, rubber end protectors to protect the bed or length adjustment, for example by telescopic tubular extensions, adjustment means and ratchet locking feet...

Generally, two auxiliary feet 6 are placed, on either side of device 1, at the location of the connection between the main plate 3 and the auxiliary plate 7. Such auxiliary feet 6 make it possible to support the load exerted by the structure of the deployed device 1 which, especially if it is loaded with objects to be supported on its upper surface, tends to bend at this joint under the effect of gravity.

In the case illustrated in Figure 2, the device 1 is in the deployed position and has no auxiliary foot 6, insofar as the deployment means 8, 9 are sized to ensure sufficient structural stability.

In particular, the deployment means 8, 9 can comprise T-shaped or cross-shaped rubber blocks, which allow attachment to the auxiliary tray 3. They can consist of rubber corners which also allow the user to note that the auxiliary plate 7 is in place in the deployment position of the device 1.

In one embodiment, the auxiliary support 7 can be pivotally mounted thanks to the deployment means 8,9, in which case it rotates on hinges placed on or under the main plate 3.

Alternatively, the auxiliary support 7 can be mounted in linear connection on the main support 3. In particular, it can be mounted thanks to deployment means 8.9 which constitute means for guiding in translation 8.9 of the main plate 3 relative to the auxiliary plate 7.

As detailed in Figure 3, such means for guiding in translation 8,9 comprise in particular a male element 9 on one of the main support 3 and of the auxiliary support 7 and a complementary female element 8 of said male element 9 on the other main support 3 and auxiliary support 7.

Thus, the male 9 and female 8 elements allow sliding, like a shelf drawer.

For structural reinforcement and easy assembly, the male 9 and female 8 elements are for example assembled in a dovetail, namely thanks to complementary shapes.

The female element 8 can comprise for example a sliding rail. This is completed by a male element that fits into the rail, for example a spar or a stud.

The rail can also be the male element 9 which is inserted into the female element 8 for guiding in translation during the deployment or retraction of the device 1.

In addition, at least one mechanical bearing can be placed in or on one of the male 9 and female 8 elements.

The mechanical bearing is for example a plain bearing or a mechanical bearing.

Ideally, care should be taken to balance the bearings. There is an even number of bearings on either side of the deployment means 8, 9, and ideally one at each end of the start and end of travel.

The slide bearing is used to transform into sliding the translational friction generated by the passage between the retracted and deployed positions.

For this, plain bearings are provided made of a soft, smooth hard material, in particular plastic or aluminum.

The mechanical bearing is used to transform into bearing the translational friction generated by the passage between the retracted and deployed positions. It may in particular consist of ball bearings. It is possible, for example, to provide a planetary gear train for optimum rolling and high mechanical resistance, while limiting the noise generated by the rolling.

As illustrated in Figure 4, the device 1 may comprise at least one removable reception structure 13 provided in or on one of the main 3 and auxiliary 7 supports.

The removable structures 13 are arranged in openings allowing them to be stored after use.

In this case, one or more cup holders 13 or glass holders 13 are provided, for example, making it possible to free up the support surface of the device 1 by offsetting the support for the cups or glass, which further increases the available surface. on device 1.

Referring to Figure 5, the cup holders 13 are attached directly to the auxiliary support 7, and are therefore made retractable by the retraction of the auxiliary tray 7 in the main tray 3.

Figure 6 illustrates a removable structure 13 which comprises a tight Plexiglas plate which allows the user to personalize the device 1 by inserting photos, or decorative images.

This removable structure can also be attached or retracted according to the needs of the user, thanks to an aluminum extrusion allowing a locking action and maintaining in position vis-à-vis a sheet of plexiglass which protects the inserted images from interspersed way.

Figure 7 illustrates the device 1 of the invention which is also designed to be integrated into a wall support 17, so as to store either the device 1, or only the auxiliary tray 2 which is attached, in particular in the case of the second embodiment for which the auxiliary plate 7 is not retracted into the main plate 3.

For example, Wall Mount 17 may have one or more wall tie hooks for hanging use.

Thus, a breakfast tray is produced capable of being modulated in size and for which a minimum bulk can be obtained, by retracting or disassembling the legs 5, 6, the main and auxiliary trays 3, 7 and the cup holders. and/or image support 13.
