Description

1BE2025 / 5747 2 forms armrests, various pieces of furniture and / or other types of objects, preferably an extension table which can be attached relatively firmly to an armrest and / or whose tabletop can be better positioned in relation to the armrest. Description of the invention5 The invention relates to an adjustable extension table in accordance with claim 1. The extension table is suitable for placement on an edge, e.g. an armrest and / or bath edge. The adjustable extension table comprises a tabletop section that includes a surface for placing objects on it, such as tableware, remote controls, or other items. A raised edge may be provided around the tabletop section. The surface can be configured to be used as a functional surface. The surface is configured to be placed in a functional position in which the surface extends primarily horizontally, for example, horizontally. The tabletop section can be primarily flat.The adjustable extension table comprises at least two retaining elements that are movably mounted to the tabletop section and are movable relative to each other between: an open state and a holding state. In the open state, the retaining elements are positioned at such a distance from each other to accommodate an edge, e.g. an armrest and / or bath rim, for example in such a way that an edge can be moved without friction / or resistance force between the retaining elements, for example by moving the extension table downwards and / or sideways over the edge. In the holding state, at least two retaining elements are placed closer together to hold the tabletop section relative to the edge, and at least two retaining elements are rotationally fixed relative to the tabletop surface to hold the tabletop section in the usage position. In the holding state, the retaining elements can be moved towards each other in such a way that they rest against an edge placed between them, e.g.such that rotation of the holder elements relative to the wall is prevented around at least two mutually perpendicular rotation axes. The holder elements may be moved towards each other in such a way that, during use, a clamping force is exerted on the edge situated between them, for example such that a friction force and / or resistance force is exerted on the edge, which hinders rotation around the edge. The holder elements may be relatively flat and / or comprise one or more curvatures. In particular, the holder elements may be adapted to the shape of an edge on which they are intended to be placed.35 The holder elements may be provided with a loaded and / or a structured surface. The surface may be provided with a microscopic structure and / or a 2025 / 5747 BE2025 / 5747 3 macroscopic structure to further increase contact forces, e.g. resistance forces, with an edge. Alternatively, an anti-slip surface may be provided on one or more of the holder elements, for example a coating, such as rubber.The at least two retaining elements are each mounted movably on the blade section in at least one adjustment direction parallel to the blade surface. In particular, the adjustment direction may run parallel to the blade surface, e.g. parallel to a longitudinal axis thereof. The at least two retaining elements may be mounted translatably, e.g. sliding, in the adjustment direction. The adjustment device may be designed in such a way that the position of the at least two retaining elements can be adjusted on an edge before placing the extension table and / or that adjustment can take place when the extension table is placed against the wall, e.g. whereby the extension table is temporarily supported. In particular, at least one of the holder elements should be able to be in a position corresponding to the holding state, after which the support table is placed against an edge, and after which another of the holder elements is moved if the respective position corresponding to the holding state is reached, e.g. against the edge, after which both holder elements are in the holding state and the support table e.g.is attached to the edge with rotational stability. The adjustment device may include a guide designed to guide the holder elements in a guiding direction, e.g. the adjustment direction. The adjustment device may include a clamp designed to clamp the holder elements with a clamping force, e.g. in the adjustment direction. The clamp may, for example, be designed as a one-hand glue clamp. The adjustment device may include a fixing designed to fix the holder elements in their respective positions and / or release them. The fixing may, for example, include a bolt, screws and / or a nut, e.g. bolts fitted with wing nuts. The adjustable extension table, for example the tabletop section and the holder elements, may be made of a commercially available material, such as metal, plastic and / or composite material. In one design form, the adjustable extension table, for example the tabletop section and / or the holder elements, is made of a wood-like material.It has been shown that such a material contributes to efficient manufacturing, in particular30 so that fewer specific tools that are often necessary for plastic and metal, such as (injection molding) molds, are required and / or that a wood-like material can contribute to an attractive aesthetic of the table. A metal, composite and / or plastic material can also contribute to a desired appearance and / or a long service life of the table.35 Thanks to the advantageous combination of a tabletop section, two holder elements movable in one direction of adjustment and an adjustment device to set the position of the holder elements in relation to the tabletop section, the extension table can be used in a relatively adjustable manner. The slots can thereby define a rotation axis that extends horizontally in the operating position. This allows for the provision of an adjustment device that is relatively simple to manufacture but nevertheless versatile.In particular, this ensures that the extension table is suitable for a relatively large number of widths and / or shapes of armrests. In particular, this allows the extension table to be placed on types of armrests other than existing extension tables, such as armrests or edges of other pieces of furniture and / or other types of objects, such as swimming pools or hot tubs. Due to the adjustability, the extension table can potentially be attached relatively firmly to an armrest, so that the risk of the armrest rotating is reduced. Furthermore, by choosing the position of the tabletop sections relative to the holder elements, a solution can be created for the specific use, e.g.Based on the specific edges and / or the type of furniture piece or object, an optimal position may be chosen in relation to the edge or armrest, for example a position where the tabletop can be reached more easily, or at a greater distance from a seating area, for example so that the seating space next to an armrest or edge is relatively less or not restricted and / or where the chance is smaller that a person touches the table while sitting and / or standing. In a specific design, the tabletop surface determines a tabletop longitudinal axis. The tabletop longitudinal axis can, for example, be the center axis of the tabletop. In a further design, at least two retaining elements are mounted movably parallel to the blade longitudinal axis and are adjustable along the blade longitudinal axis by means of the adjustment device. It has been shown that advantageous adjustability can be achieved in this way. 25 In a design, at least one of the at least two retaining elements is rotatable relative to the blade surface in the open state.The minimum-stone holder element can, for example, be provided with a rotatable attachment to the blade section, for instance where the adjustment device connecting the holder element to the blade section is rotatable. The minimum-stone holder element can be rotatable from the open position towards the holding position. In this way, for example, a clamping of non-releasing form edges and / or armrests can be achieved. As additions / or an alternative, the minimum-stone holder element can be rotatable in the holding position, for example to rest even better against the edges / or armrest. 35 In one design form, the adjustment device comprises a guide that extends, for example, mainly parallel to the blade surface. The guide can, for example, 2025 / 5747 BE2025 / 5747 5 extend parallel to the longitudinal axis of the blade section. At least two retaining elements are each mounted in the guide. In this way, the fastening can be further improved. In particular, such an abutment of a retaining element against the edge on either side of the edge can be achieved.One or more guides may be provided, whereby at least two retaining elements are mounted in the same and / or mutually different sections of the guides. The multiple guides may be mounted at a distance from each other, for example at a distance perpendicular to the longitudinal axis of the blade section. In this way, the retaining elements can rest against an edge at different positions to possibly further improve stability. In one design, the adjustment device comprises at least two guides, with at least two retaining elements mounted in each of the respective guides. In one design, the adjustment device comprises at least three retaining elements, for example four, whereby at least one of the at least two guides has at least two retaining elements mounted, which are movable relative to each other between the open and holding states.In a version with four retaining elements, for example, two guides can be provided positioned at a distance perpendicular to the longitudinal axis of the blade section, with two retaining elements mounted movably in each guide in the direction of adjustment. In this way, contact on either side of the edge can be achieved at different positions along the edge. In one design form, the extension table comprises at least one slot and at least two retaining elements, with at least two retaining elements positioned on either side of the same slot. In this way, it has been shown that the retaining elements can be rotated alongside each other, which can be advantageous, for example, when used as a table, because a relatively low position of the blade surface could thus be obtained. In one design form, the extension table comprises at least two slots running parallel to each other, but placed at a distance parallel to the blade section. Thus, each guide can comprise a slot. This design form can, for example,comprising at least three or at least four retaining elements, where, for example, two retaining elements are installed in each of the two parallel slots. In this way, a relatively stable positioning, e.g. on an edge or on a surface, can be achieved. In a further design, the extension table comprises a guide with at least two slots placed one below the other, where at least two retaining elements are installed on either side of the two slots placed one below the other. In an even further design, the extension table comprises two sets of two slots placed one below the other, where the two sets are placed at a distance parallel to the tabletop section from each other. In a single design, at least two retaining elements extend mainly vertically in the holding state. It has been shown that such an extension results in a longer moment arm and thereby a relatively stable contact against the edge or armrest.In one design form, the extension table comprises at least one leg, which is designed to be placed on a floor surface. By means of a single leg, the maximum weight-bearing capacity and / or stability of the tabletop section could be further improved. Multiple legs may be provided, for example at least 2 or 4. The leg or legs may each be provided with a foot section, for example a relatively flat and / or rounded foot section for relatively stable placement on a surface. By means of the leg or legs, the usability of the table for various applications is further increased. For example, the extension table could comprise at least two support elements and at least one leg. Alternatively, at least two legs may be fitted, so that the tabletop section can be held in the usage position both on an edge, by means of the support elements, and on a floor surface, by means of the legs. For example, there may be three or four legs. fitted, with which the blade section can be placed on a floor surface. In a design form, at least two holder elements form the legs.The retaining elements can be shaped in such a way that they are suitable for supporting the blade section on a base surface. In this way, the blade section can be used both on an edge and freestanding by means of the main elements.25 In one design form, the guide comprises a slot, e.g., extending widely across the blade surface. Such a guide is relatively compact, stable, efficient to manufacture, and / or has some aesthetic value. In particular, two slots running parallel to each other can be provided, whereby30 the retaining elements are installed in both slots, e.g., by means of a connection such as a bolt. The two slots can run parallel to each other. In this way, the retaining elements can, e.g., be slidable within the slot in a predominantly vertical position, whereby this rotation in the operating position further hinders sliding, e.g., by friction of the respective installations in the two respective slots.In particular, the resistance to rotation can be such that further shifting of the retaining elements in the slot can subsequently be prevented. 2025 / 5747 BE2025 / 5747 7 The slot can be a fully through slot. Such a slot is relatively simple to manufacture and / or appears to allow for simple assembly of a fastening end, for example when the fastening end comprises an opening that can be aligned with it. Fastening can then take place, for example, by means of a pin-hole connection, bolts / or screws, and can be relatively easy to remove. The continuous opening formed by the slot can be continuous in one direction parallel to the blade surface, e.g. such that the opening is continuous in the horizontal direction in the operating position. It has been shown that this allows for an aesthetically pleasing design to be achieved and / or facilitates disassembly or adjustability. In this way, fastening can take place, e.g. by means of a horizontal dowel joint, e.g. a horizontally running bolt.For advantageous reasons, the slot can be provided near an outer edge of the tabletop, so that the adjustment mechanism is relatively easily accessible for adjusting the holder elements, for example less than 10 cm, such as less than 5 cm from the outer edge of the tabletop.15 In one design form, the guide comprises a support extending visibly from the tabletop surface, in which the slot is made. The support can be, for example, a support beam or lath on which the tabletop section is mounted. The support can be designed to increase the load-bearing capacity of the tabletop section. By providing the slot in the support, compactness, stability, manufacturing, and / or aesthetics can be further improved. In a design comprising at least two holder elements, a fixing end is used to adjust the position of the respective holder elements on slot 25. The fixing end can be attached to the blade section via the adjusting device. The fixing end can, for example, be provided with an opening for connection to the adjusting device, such as a screw and / or bolt opening.The fastening ends, in particular the respective openings thereof, can be located mainly horizontally in the operating position, e.g. horizontally, next to the slot30 and be connected to the slot by means of an adjustment device, such as a bolt, screw or pin, so that an easy-to-manufacture and / or-to-use fastening is obtained. In one design form, the slot is positioned at such a distance from the blade section, e.g. from the blade surface, that the respective fastening ends of the two retaining elements are rotatable with respect to the blade surface. 2025 / 5747 BE2025 / 5747 8 In addition to the distance between the slots and the blade section, as an alternative, the shape of the respective fastening ends can be adjusted to increase an effective distance, for example by rounding the corners thereof. The shapes and / or distance of the respective mounting ends may be such that the respective holder elements have a rotatability of a maximum of 45 degrees, for example a maximum of 30 degrees.In this way, a limitation of rotatability can be achieved by means of a predetermined shape and / or distance. Such a limitation can be advantageous because, in the event of the adjustment mechanism unexpectedly becoming loose, the maximum rotation of the blade section can be restricted. Furthermore, it has been shown that the limitation can further improve the stability of the holding elements in the holding state, because the play thereof at the maximum angle is reduced by the limitation. Finally, it has been shown that a limitation of the legs contributes to increased stability of the extension table when it is placed on a floor surface by means of the legs, e.g., freestanding. In a single design, the support comprises multiple continuous slots that extend at least partially along one another. The at least two retaining elements can be arranged in the same and / or mutually different slots. The multiple slots can be arranged at a distance from each other, for example at a distance perpendicular to the longitudinal axis of the leaf section.In this way, the retaining elements can rest against an edge at different positions to potentially further improve stability. 20 In one design form, the adjustment device comprises at least two slots and the at least two retaining elements are each installed in a respective single slot. Alternatively, the at least two retaining elements can each be installed in more than one slot. It has been shown that stability, for example rotational stability, can be further improved.25 In one design form, the adjustment device comprises at least three slots, for example four, in which at least two of the at least three slots and at least one retaining element are fitted, which is movable between the open and holding states. In a version with four retaining elements, for example, two guides can be provided, placed at a distance perpendicular to the longitudinal axis of the blade section, which are also provided with two slots, in which two retaining elements are mounted in the adjustment direction in each of the two slots.In this way, each retaining element can be secured relatively firmly in two slots. The various slots can thus increase the total fastening force, without a relatively large force having to be applied to a single slot. In particular, the slots can be positioned at different distances from the tabletop. This allows for the provision of an easy-to-manufacture and / or easy-to-use adjustment mechanism and / or an adjustment mechanism that is perceived as aesthetically pleasing. In one version of the extension table, at least two retaining elements are attached to the tabletop section in a detachable manner. It has been shown that detachability results in a relatively compact, easy-to-store extension table. For example, storage space for detached retaining elements can be provided under the tabletop section, such as between the supports and / or between the guides. According to another aspect, the invention relates to a piece of furniture10 comprising an edge, e.g.an armrest, equipped with an adjustable extension table according to one of the design forms disclosed herein, in which at least two retaining elements can be placed on the rim in the holding position. The shape, dimensions and / or materials of the retaining elements and the rim can, for example, be matched to each other, e.g. to achieve high stability and / or rotational stability in the holding position.15 In one design form, the piece of furniture is a bath, for example a whirlpool or jacuzzi, equipped with a bath rim, in which at least two retaining elements can be placed on the bath rim in the holding position, such that the horizontal position of the tabletop section relative to the bath water contained in the bath is adjustable. It has been shown20 that the adjustable extension table according to the invention is relatively well suited for use on rims, due to the adjustability of the retaining elements to adapt them to the shape of the bath rim.In addition, the leaf section shall be moved in such a way that it does not obstruct persons in the bath and / or in such a way that it does not lie above the water, which may be advantageous for moisture- and / or condensation-sensitive objects placed on the leaf surface. According to another aspect, the invention relates to a method for adjusting an extension table placed on an edge, e.g. an armrest and / or bath rim, e.g. an adjustable extension table according to one of the forms of execution disclosed herein, comprising the steps of: • moving at least two retaining elements of the extension table from an open state to a holding state for holding the leaf section attached to the retaining elements in the operating position; and • setting the position in the holding state of the at least two retaining elements relative to the leaf section by means of an adjustment device.2025 / 5747 BE2025 / 5747 10 The method can be carried out using one or more of the versions disclosed herein for the adjustable extension table, and corresponding benefits can be achieved as described herein for the adjustable extension table. In particular, the method can be carried out in a version where the method involves rotating one of the 5 holder elements in the slot around the connection between the holder element and the slot, which extends mainly horizontally in the operating position. According to a further version, the holder element is rotated in such a way that it locks more firmly in the slot and sliding of the holder element in the slot is made more difficult. 10 It has been shown that the advantageous combination of adjustment devices and two holding elements can also be of advantage in pieces of furniture other than a table, for example also in pieces of furniture other than a table according to the invention, such as a chair.Such a piece of furniture may also expressly be the subject of a separate application, with embodiments as described within the embodiments of the extension table, in particular as described in the clauses and conclusions thereof.

In the figures, the same reference numbers and characters are used to refer to corresponding components or to components that have a corresponding function. 10 Detailed description of the figures Figure 1 shows schematically in perspective an adjustable extension table 1 according to a design of the invention. The adjustable extension table 1 is suitable for placement on an edge, e.g. an armrest and / or bath edge and comprises a leaf part 2 which comprises a leaf surface 15 3 for placing objects thereon. The leaf part 2 is designed to be placed in a working position, as shown in Fig. 3, in which the leaf surface extends mainly horizontally.The extension table1 in both shown versions comprises at least two, namely four, holder elements4 which are movably mounted to the tabletop part 2 and are movable relative to each other between an open state for receiving an edge99, e.g. an armrest and / or bath edge, between two holder elements4, as shown in Fig. 3, Fig. 4 and Fig. 8. The holder elements4 are movable in a holding state, in which at least two holder elements4 are placed closer together to hold the tabletop part 2 relative to the edge99, and in which at least two holder elements4 are rotationally fixed relative to the tabletop surface3 to hold the tabletop part 2 in the usage position. In the holding state, the holder elements4 can be moved towards each other in such a way that they rest against an edge99 placed between them, e.g. such that rotation of the holder elements 4 with respect to the wall around at least 30 rotation axes perpendicular to each other is prevented.The holder elements can be moved towards each other in such a way that, during use, a clamping force is exerted on the edge situated between them, for example in such a way that a friction force and / or resistance force is exerted on the edge, which makes rotation around the edge difficult.35 The holder elements4 are planar in the shown design but may alternatively or additionally include one or more tensile curves. For example 2025 / 5747 BE2025 / 5747 12 the holder elements4 could be adapted to the shape of an edge on which they are intended to be placed. The holder elements may be provided with a charged and / or a structured surface. The surface may be provided with a microscopic and / or a macroscopic structure to further increase contact forces, e.g. resistance forces, with an edge5. An anti-slip surface may be provided on one or more of the holder elements, for example a coating, such as rubber.The at least two holder elements4 are each mounted on the blade section in at least one adjustment direction parallel to the longitudinal axis of the blade surface3 via adjustment device5, namely translatable, e.g. by sliding.10 The adjustment device5 is designed to set the position in the holding state of the at least two holder elements4 relative to the blade section2, such that the position of the at least two holder elements4 in the holding state relative to the blade section 2 is adjustable in the adjustment direction. The adjustment device5 is designed so that the position of the at least two holder elements4 is adjustable before placing the extension table on an edge15 and / or that the adjustment can take place when the extension table is placed against the wall, e.g. whereby the extension table is temporarily supported. The adjustment device 5 comprises, in the shown versions, a combination of a bolt inserted through the holder element 4 and slot 6, which is fixed by means of a nut attached thereto.20 The mounting ends of the holder elements(4) are rotatable with respect to the blade surface around the rotation axis extending horizontally in the operating position by means of a rotation movement R. Slot6 is a through slot and the mounting ends are located horizontally next to the slot in the operating position, and are connected to the slot by means of the adjustment device, so that the rotation axis and the rotation R that is possible is defined by the connection between the respective mounting end and slot6. The slots6,6 extend over the greater part of their extensions near the outer edge of the tabletop, namely less than 10 cm from the outer edge, e.g. less than 5 cm from the outer edge.30 The tabletop surface3 defines a tabletop longitudinal axisL, which is the center axis of the tabletop part2, and at least two retaining elements4 are each mounted movably parallel to the tabletop longitudinal axisL and adjustable by means of the adjustment device5 along the tabletop longitudinal axisL.At least one of the at least two holder elements 4 is rotatable relative to the blade surface 3 to the holding position in the open state, as shown in Fig. 7-8. 35 The holder element 4 can be provided with a rotatable attachment to the blade part 2 by means of the fixation, because the adjustment device 5 that connects the holder element to the blade part 2025 / 5747 BE2025 / 5747 13 is rotatable. The holder elements 4 in Fig. 1 are rotatable from the open state towards the holding position. As additions / or alternative, at least one holder element 4 can be rotatable in the holding position, as in Fig. 7 and 8, for example to lie even better against the edges / or armrest. The holder elements can be rotated in such a way, as shown, for example, in Fig. 7 or Fig. 95, that the holder elements4 clamp themselves in the slots6 by means of the adjustment means5 and that further sliding of the holder elements4 within the slots is thereby made difficult.The adjustment device 5 comprises a guide 6 extending mainly parallel to the blade surface 3 and at least two retaining elements 4 are each mounted in the guide 610. There are two guides 6, 6' provided, which are arranged at a distance from each other at a distance perpendicular to the longitudinal axis 1 of the blade part 2. The adjustment device 5 of Fig. 1 comprises at least two guides 6 designed to guide the retaining elements 4 in a guiding direction, namely the adjustment direction 1, and in which at least two retaining elements 4 are each mounted in a respective guide. In this version, the adjustment device 5 comprises a fixing designed to fix the retaining elements 4 in their respective positions and / or release them, and in this case comprises a bolt and wing nut, but could also comprise screws, a clamp or other fixing. The extension table 1 of Fig.1 comprise at least three holder elements4, in particular four, in which at least one of the at least two guides6, namely in both 20 guides6, at least two holder elements are fitted, which are movable relative to each other between the open state and the holding state. The at least two holder elements4 extend mainly vertically in the holding state, but are somewhat rotatable therein. The adjustable extension table1, in particular the top section 2 and holder elements 4, 25 are made of a commercially available material, namely a wood-like material, but in other versions could also be made of, for example, metal, plastic and / or composite material. The design of Fig. 2 comprises at least one leg7, namely four, two of which are visible in the side view, whereby the legs7 are arranged to be placed on a 30 base surface, so that the blade part 2 can be held in the working position both on an edge and on a base surface.At least two holder elements4, in particular all four, form the legs7 in this design. Alternatively, at least two holder elements4 could be provided and at least one leg, for example two, so that the blade section235 can be held in the service position simultaneously both on an edge, by means of the holder elements, and on a bottom surface, by means of the legs. 2025 / 5747 BE2025 / 5747 14 The guide6 comprises a slot extending across the blade surface. The guide6 comprises a support8 extending across the blade surface, with the slot6 in the support8. At least two holder elements4 comprise a fastening end9 with which the respective holder elements4 are adjusted to the slot6. The 5 fastening end9 is attached to the blade part via the adjusting device 5 and is provided with an opening for connection with the adjusting device 5, through which the adjusting device 5 can extend, namely a screw and / or bolt opening through which, in this version, the bolt is inserted.The slot6 is positioned at such a distance from the blade section2 that the respective mounting ends9 of at least two retaining elements4 are rotatable with respect to the blade surface3. In addition to the distance between the slot and the blade section, as an alternative, the shape of the respective mounting ends may be adjusted to increase an effective distance, for example by rounding their corners. The shape and / or distance of the respective mounting ends may be such that the respective retaining elements have a maximum rotatability of 45 degrees, for example a maximum of 30 degrees with respect to the blade surface3. The carrier8 comprises multiple through slots6 that extend at least partially alongside each other. The multiple slots6 are located at a distance from each other perpendicular to the longitudinal axis1 of the blade section2. The adjustment device5 comprises at least two slots20 6 in this design, and at least two holder elements4 are each arranged in multiple slots. The two slots are arranged at different distances from the blade section2.At least two holder elements4 are thus installed here in the same slots6, but could also each be installed in mutually different slots6, e.g. each in a respective single slot6.25 In the shown design, the adjustment device5 comprises at least three slots, namely four, of which 2 are visible in the side view. Thus, two guides are provided, placed at a distance perpendicular to the longitudinal axis1 of the leaf part2, which are provided with two slots6, in which two holder elements4 are installed in each of the two slots6, movable in the adjustment directioni. It follows from this that in at least two of the at least three slots6 at least one holder element4 is installed, which is movable between the open state and the holding state. At least two retaining elements4 are detachably mounted on the leaf section 2. Underneath the leaf section 2, between the supports8 with guides, a storage space for detached retaining elements4 is provided.35 The design shown in Fig. 9 depicts a variant in which at least two retaining elements4 are mounted on either side of the same slots6.In particular, two guides may be provided, comprising a set of two parallel slots, where the holder elements are installed in both of the slots located one below the other. The design of Fig. 10 shows a table in different orientations. Each guide comprises a set of two slots, respectively two slots, which are placed one below the other. There are two holder elements in both of the slots placed one below the other. In the same side of the two slots placed one below the other, but the holder elements could also be installed on either side of the slots, respectively 6',6', as i.
