Description

TELESCOPIC STORAGE DEVICE

Technical area

The present invention relates to a storage device with horizontal shelves and vertically movable for a container of a predetermined internal height and open on the upper face.

Prior art

Storage containers such as trunk, suitcase, trunk, basket, drawer and the like offer the advantage, unlike shelf storage cabinets, to optimize their storage capacity by minimizing their overall volume and have a small footprint in height . On the other hand, they are often made up of a single interior space which is too large to be practical and which imposes on the user an empirical and constraining method of storage. In addition, their top-opening system induces a restriction of the visibility of the content at the top layer while limiting the accessibility of the bottom of the container and prohibits the installation of horizontal shelves that could facilitate the organization and the Storing the contents, as for a shelf cabinet, by dividing the interior volume into several storage spaces.

US Patent No. 2006/0000681 issued to BARKER DEBORAH proposes an attempt to organize the interior of a suitcase by movable shelves. It describes a set of horizontal shelves connected by means of bellows elements to structures constituting the body of the bag, composed of two sliding segments and whose expansion capacity is limited to twice their folded length, allowing elevation and limited spacing of shelves.

Such a system however imposes on the bag: a cubic shape, an additional opening system by disassembly of the front side panel to access the lower storage spaces and a strict limitation of the number of shelves due to the small amplitude of separation obtained , which makes it particularly unsuitable for the flat shape of the standard type of luggage and more generally to all containers whose only opening is on the upper face. It would therefore be advantageous to solve these problems with a device adapted to this type of container which has both a reduced footprint in height for storage and direct access to all its content for easy storage.

Presentation of the invention

To solve one or more of the aforementioned disadvantages, a telescopic storage device for a container of a predetermined internal height open on its upper face, comprises: at least one vertical sliding means, consisting of at least three rigid sliding segments said sliding means being secured to the container by its lowest sliding segment,

At least one substantially horizontal shelf (or storage plane) connected to said sliding means, such that said device is movable between:

A folded position, obtained by folding the sliding means in which the height of the device is less than the predetermined internal height of the container so that at least one shelf divides the interior volume of said container into several storage intervals and that each storage interval allows the storage of at least one content,

An unfolded position, obtained by extension of the sliding means, wherein the height of the device is greater than the predetermined internal height of the container so that each shelf is raised along said sliding means and the height of the less storage interval is increased and each storage interval is accessible, to allow the manipulation of each content.

Features of particular embodiments are: The device comprises several shelves, interconnected by at least one flexible connecting element, the highest shelf being connected to the top of each sliding means.

- The device comprises several shelves, connected to each other by less a flexible connecting element, the highest shelf being fixed at the top of each sliding means.

- Each shelf is connected via a connecting element at the top of a sliding segment of each sliding means such that each connecting element is fixed at its lower end to a shelf and at its upper end, at the top of a sliding segment not secured to the container.

The device comprises several shelves, such that each shelf is connected to a lower sliding segment than a shelf adjacent to it and upper and such that each connecting element connecting a designated shelf is longer than each connecting element connecting a shelf. adjacent and above said designated shelf.

This connection mode makes it possible, among other things, to use rigid connecting elements to connect the shelves, which generates a greater stability for the shelves in the extension and folding phases and in the two defined positions of the shelves. device.

- Each sliding means is fixed, by its lowest segment, on a horizontal plane, such that said plane bearing on the bottom of the container is secured to the bottom of the container by a releasable fastening system.

- Each sliding means is secured to the container by its lower sliding segment, by a releasable fastening system.

- The sliding means is composed of hollow sliding segments interengaging one in the other telescopically. The use of this type of sliding means makes it possible, among other things, to reduce the risk of interaction between the content and the sliding segments during the sliding process by preventing clothes, for example, from being caught between two sliding segments.

- The device comprises at least two sliding means and said sliding means are secured to each other by their highest sliding segment and via a connecting bar.

This allows, among other things, a process of unfolding and synchronized folding of the sliding means.

- A shelf is fixed at the top of each sliding means and said shelf serves as a lid by closing the container in the folded position of said device.

This allows, among other things, the user to perform in one action the opening of the container and the unfolding of the device. - The sliding means comprises a brake holding it in the unfolded position.

The use of the device is thus facilitated by freeing the user from holding the device in the unfolded position.

At least one shelf comprises at least one orifice through which a sliding means freely passes.

This allows, for example, to position in the center of the container, a sliding means which passes through each shelf through a hole.

DETAILED DESCRIPTION OF EMBODIMENTS With reference to FIG. 1, a device positioned in a container 1 comprises four vertical sliding means 3 in the form of four telescopic legs. Each telescopic leg has four rigid and hollow segments sliding into each other. These four telescopic legs are supported on the bottom and in the corners of the container which, for the sake of clarity of the drawing, the other sides have not been shown.

The sliding means support four horizontal storage planes, or shelves. The intermediate and lower shelves are connected to the upper shelf by means of four connecting elements 7 such as flexible cords. A content 9 illustrated by a box is positioned on an intermediate shelf. The upper shelf 5 (or upper plane) is fixed at the top of the sliding means by a fastening means 11 such as a screw or a rivet. The shelves are made of a rigid material such as plastic. The operating mode of the device is as follows. A lifting action of the user on the highest shelf 5 causes the unfolding of the sliding means 3 as well as the raising and spacing of the different shelves 5, FIG. 2. The sliding means are deployed in such a way that the device has a height greater than the predetermined internal storage height H of the container 1. The lower shelves are suspended under the upper shelf by the flexible nature of the connecting elements 7 which determine by their lengths the maximum spacing of the shelves, allowing an elevation and distribution of the shelves along the height of the device and the sliding means.

The deployed device has, outside the container, all the interior storage space arranged with horizontal shelves at enlarged intervals height and thus facilitates access and management of the content. Thus, in this arrangement, a user has easy access to each storage interval to manipulate content and store, for example, clothing.

When the container 1 must be closed, an inverse mechanical action, for example by pressing on the upper shelf, causes the folding of the sliding means and the successive approximation of the intermediate shelves. The device is such that the rigid sliding segments fit into each other and the height of the folded device is less than the internal storage height H of the container 3. Thus the container can be closed by a cover 13, FIG. 3.

In the folded position of the device, the internal storage volume of the container is reduced only by the telescopic supports and by the thickness of the shelves which are close to each other and which divide said interior volume of the container into several storage intervals. The contour shape and dimensions of the different shelves are designed to allow the device to unfold and fold freely and smoothly with the container.

The lower and intermediate shelves have orifices 15 through which the telescopic supports whose diameter is determined to allow the free sliding of the telescopic supports which pass through them. Each shelf thus provided with an orifice for each sliding means is better guided during its folding and unfolding and is stabilized in unfolded and folded position of the device. The flanks 17 define the intermediate shelves on three sides. They are integral with the shelves in their lower parts and are made of a rigid material. Preferably, the sliding means are self-locking and allow the device to be held in the high position.

In a variant, FIGS. 4 and 5, the orifices of the intermediate shelves are extended on the side of the upper face of the shelves by tubular structures or protective sheath 19 constituting a protection for the sliding of the telescopic supports 3 against a possible gene by the contents. 5. It should be noted that the sidewalls 17 and the protective cases 19 are made so that their height allows to close the container in the folded position of the device. In the second embodiment, FIGS. 6 and 7, the four telescopic supports 3 are fixed on the bottom and in the corners of the container 1 each having three sliding segments of different diameters, they are positioned with their widest segment towards the bottom. and are fixed in the corners of the upper shelf by their upper ends. The telescopic supports are self-locking and allow the device to remain in the high position. The shelves 5 are made of rigid material. The intermediate shelves 5 have dimensions determined to allow them a free movement of vertical elevation without a hitch with said telescopic supports 3. The intermediate shelves are connected to each other and to the upper shelf by connecting elements 7 which are made of soft material similar to cords and which are fixed in their angles and on their upper and lower faces. In unfolded position of the device, Figure 6, the lengths of the connecting elements 7 allow similar intervals between the different shelves 5. The lower shelf makes accessible the storage space of the bottom of the container by raising it at the upper edge said container. The intermediate shelves are in abutment with the contents 9 illustrated by boxes and on the bottom of the container 1, in the folded position of the device, FIG.

The third embodiment, Figures 8, 9 and 10, comprises the same elements as the previous embodiment, it differs in that the sliding means 3 are supported in a housing 21 of the wall of the container 1, it is also different in that the upper shelf 5 serves as a lid by closing the container 1 in the folded position of the device, Figure 9, wherein the height of the device is less than the internal height H of said container. Figure 10 shows the section of the sliding means 3 of Figure 8 which is substantially rectangular in shape.

In the fourth embodiment, FIGS. 11 and 12, the device comprises three shelves 5, the highest shelf is fixed to connecting elements 7 made of flexible material at the upper ends of the sliding segments of the highest level of the supports. The shelves are interconnected by flexible connecting elements 7. The telescopic supports are fixed on the bottom of the container 1 and have three sliding segment, their extension and folding process is controlled by electric motors 23, housed at their base, a battery 25 supplying said engines. In the unfolded position of the device, FIG. 11, the various shelves 5 are suspended by their flexible connection elements 7. In the folded position of the device, FIG. 12, the shelves 5 abut with the contents 9, illustrated by boxes, and the container bottom 1. A lid 13 closes the container. In the fifth embodiment, Figures 13,14 and 15, the device comprises four telescopic legs 3 resting on the bottom of the container 1 which are secured to said container by releasable fastening systems 26, such as rotary latches. 13, the rotary latches 26 are in the closed position, and make each telescopic support 3, integral with the container 1. When the latches 26 are open, Figure 15, each telescopic support 3 is separated from the container 1 and the device can be removed said container. Rigid connecting bars 27 made of light metal are fixed by interlocking and gluing on the highest sliding segments and thus firmly connect the tops of the telescopic legs two by two. The telescopic legs 3 have a brake that allows them to maintain their unfolded position, a trigger 29 releases the brake mechanism. Flanks 17 made of flexible textile material delimit the internal storage space of the intermediate shelves 5 on three sides. The flanks help to keep the stored contents from overflowing and give the user an indication of the maximum storage height for each shelf. The flanks 17 line the upper shelf 5 on the four sides, and connect said upper shelf to the connecting bars 27. The three shelves 5 are interconnected by flexible connecting elements 7 which are fixed on the upper and lower faces of the The shelves are made of a flexible textile material stretched over a rigid metal frame structure. A shelf thus produced adapts to the shape and volume of the content stored on the shelf immediately below it when the device is folded, which gives the user a margin of error when evaluating the volume. allowable storage for each shelf. The content 9 stored on the shelves is illustrated by boxes.

In order to lower the device, FIG. 15, the user presses on the triggers 29 to release the brake mechanism of the telescopic legs 3. In FIG. 13, the height of the folded device is less than the internal height H of the container which is closed by a lid 13, the sides of the shelves intermediates not shown for clarity of drawing.

In the sixth embodiment, Figures 16, 17 and 18, the device comprises a single shelf 5 which has flanks 17 on four sides. Link bars 27 integrally connect the four sliding means by their top. The flanks 17 connect the shelf 5 to the connecting bars 27. The sliding means 3 are of sliding type, have three sliding segments and are fixed on the outer walls of the container by fixing lugs 30. The dimensions of the device are width less than the container 1 so that its single shelf 5 cuts only a portion of the internal volume of said container when the device is in the folded position, Figure 18, leaving a free space for storage, next to the device whose height is equal to the internal height H storage container. The content 9 is illustrated by a box. The container 1 has rollers 31 and can, for example, be slid under a bed acting as a cover 13. Figure 18, the forward sliding means 3 are shown while the front face of the container is not shown for clarity of drawing. Figure 16 shows the sectional shape of sliding type sliding means 3 of Figure 17

In the seventh embodiment, Figures 19 and 20, the telescopic supports 3 are fixed by interlocking and gluing on a plane 33 bearing on the bottom of the container 1. Figure 19, unlockable fastening systems 26 such as, rotary latches are in the closed position, and make integral the plane 33 of the container 1. When the latches 26 are open, Figure 20, the plane 33 is disengaged from the container 1 and the device can be removed from said container. The upper shelf 5 made of rigid material has flexible flanks 17 and is connected by connecting elements 7, made of a rigid material such as hard plastic, to the different sliding segments the highest telescopic supports. The other shelves 5 are connected by flexible connecting elements 7 to segments of the same level. In the folded position of the device, Figure 19, the lower shelf is in abutment on the content 9 illustrated by a box. In the unfolded position of the device, Figure 20, the lower shelf rises to a height allowing easy access to the bottom of the container by the upper face of said container.

The use of flexible connecting elements, gives a shelf greater tolerance of adjustment to the volume of content located on the adjacent and lower plane, giving the user greater freedom in the use of different storage spaces.

In the eighth embodiment, FIGS. 21 and 22, the device comprises four telescopic supports 3 comprising five sliding segments of different diameters. The telescopic supports are self-locking, allow the maintenance in high position of the device. The shelves 5 are made of rigid material, and are positioned between the telescopic supports 3, their dimensions are determined to allow a free movement of vertical elevation smoothly with said telescopic supports. The upper shelf 5 is connected to the highest tubular segments, by connecting elements 7 made of a rigid material (hard plastic). The other two shelves 5 are connected to each telescopic support 3 by flexible connecting elements 7.

In unfolded position telescopic supports 3 Figure 21, the shelves 5 are spaced from each other, each shelf being maintained horizontally by its connecting elements 7 which have the same length. In the folded position of the telescopic supports 3, Figure 22, the shelves 5 are close together, the lengths of the connecting elements 7 produce similar intervals between the bottom of the container 1, the various shelves 5 and the lid 13 of the container.

The rigid connecting elements 7 of the upper shelf 5 induce a downward shift of the surface of the shelf relative to the tops of the sliding segments to which it is connected, this shift makes it possible to create, in the folded position of the supports, a interval between its surface and the lid 13 of the container and induces the corresponding storage space.

The connecting elements 7 create larger offsets for the lower shelves 7, which allows to generate, in the folded position of the telescopic supports 3, and despite the juxtaposition of the upper ends of the sliding segments to which they are connected, intervals between the surfaces. shelves. Thus the storage intervals between the shelves are generated, for the folded position of the device, by the differences in progressive lengths between their respective connecting elements.

When a telescopic support unfolds, its sliding segments slide relative to each other which results in the spacing of their upper ends, each shelf being connected to a different segment, the unfolding process increases the intervals between the different shelves and achieves the goal of improving the accessibility of different storage spaces by increasing their height . The maximum number of modular shelves for this embodiment depends on the number of sliding segments constituting the telescopic supports.

The following combined data determine the elevation heights of the different shelves 5 and the heights of their respective intervals in the unfolded position of the telescopic supports 3: lengths of the connecting elements 7; length of the telescopic supports 3 and number of their respective sliding segments; choice of sliding segments to which they are connected.

In the ninth embodiment, FIGS. 23 and 24, each telescopic support 3 comprising two sliding segments bears in a housing 21 outside the container 1. During the process of extending and folding a telescopic support 3, its sliding segment the lower slider in the housing 21 which acts as a third sliding segment and allows, in the unfolded position of the telescopic support, to fill the objective of elevation of each shelf 5 and increasing the heights of the storage intervals to make them accessible.

The shelves 5 are connected to the tops of the sliding segments of the telescopic legs 3 by rigid connecting elements 7 positioned vertically. The highest shelf 5 is connected to the highest sliding segment of each telescopic support 3. The lower shelf 5 to the higher shelf is connected to a telescopic support by a sliding segment lower than the upper shelf each shelf is connected to sliding segments of the same level. The connecting elements 7 of the lower shelf 5 are longer than the connecting elements of the upper shelf.

All the connecting elements are made of a rigid material which induces specific constraints, the lengths of the various connecting elements must be determined to allow the complete folding of the telescopic supports. A rigid link member 7 positioned vertically requires a specific attachment such as a fixing ring 37 which produces a horizontal shift of its body relative to the surface of the sliding segment on which it is fixed, in order to eliminate the inadvertent blocking of the body of the abutting connecting element, during the folding of a telescopic support 3, against the angles produced by the differences in diameter between the different sliding segments . In order to allow the juxtaposition of the rigid connecting elements 7 and the folding of the telescopic supports 3, their fasteners 37 must offset, with respect to each other, the connecting elements connecting the same telescopic support and create a larger offset for an element. link connecting a designated shelf only for a connecting member connecting an adjacent shelf and lower to the designated shelf. The offsets obtained by the fastening rings 37 also make it possible to position the sliding means 3 outside the container 1 which has notches 38 on its upper edge in which the fixing rings 37 come to juxtapose in the folded position of the FIG. 24, for closing the container by the lid 13.

In the tenth embodiment of FIGS. 25, 26, 27 and 28 the device is adapted to a container 1 of cylindrical shape, it comprises a single telescopic support 3 fixed to the center of the container 1, the shelves 5 are disk-shaped. The upper shelf 5 is fixed to the top of the telescopic support and serves as a lid by closing the container in the folded position of the device, Figure 28, it comprises a handle 39 facilitating its grip to open the container 1 which has hooks 41 allowing locking the lid. The intermediate shelf is connected to the top of a sliding segment by a rigid connecting element 7 of hollow tubular shape, it is provided with a central orifice 15. The telescopic support 3 passes through the orifice 15 and the connecting element 7 which allow by their width of inner diameter, free sliding of the lower sliding segments. Figure 27 shows the junction between the connecting element 7 of Figure 28, the intermediate shelf 5 and the telescopic support 3. In the eleventh embodiment of Figures 29, 30, 31 and 32, the device comprises four telescopic legs 3 fixed on a horizontal plane 33 and fixed by their tops to a shelf 5. The intermediate shelf 5 has holes through which the telescopic legs 3 to which it is connected by tubular connecting elements 7. The intermediate shelf and the plane 33 have flanks 17. The device is functional without a container. Figure 31, the device is positioned in a container 1 open on a side face. Figure 32 shows a variant of the device of Figure 30 which has no sidewall and which is covered by a container 1 open on the underside. The invention has been illustrated and described in detail in the drawings and the foregoing description which is to be considered illustrative and given by way of example and not as limiting the invention to this description alone. Many alternative embodiments are possible.
