Description

The invention relates to a multifunctional piece of combination furniture which can be used simultaneously as table furniture, in particular as standing table, and alternatively as a dart station, according to the preamble of claim 1.In the field of dart sports, it is known to store dart panes in dart cabinets which are suspended on a wall, for example, in living rooms and conceal the view of the respective dart pane in the closed state, so that the panes do not impair the visual impression of a living room. By opening the two door leaves arranged on the front side of a dart cabinet, access to the dart pane is released, so that the dart pane can be used as a target pane for the ejected arrows in a dart match.However, due to their size, such dart cabinets can mostly only be used with restrictions for professional dart sports, since e.g. the prescribed height of the dart board above the floor of about 1.73 m and also the distances to be exactly maintained between the board and the discharge line of 2.37 m must only be observed with not inconsiderable optical restrictions.Table furniture in a wide variety of configurations is also known from the prior art, which are used, for example, as meeting and presentation tables in offices and display rooms or also as desks in the private sector. However, these items of table furniture cannot be used as combination furniture, so that these usually have the sole function of a table.Accordingly, it is an object of the present invention to provide an optically appealing piece of furniture which can be used in particular as a meeting table and which can alternatively also be used as a dart station which satisfies the rules specified in the dartport.This object is achieved according to the invention by a piece of furniture having the features of claim 1.According to the invention, a multifunctional piece of furniture, which can be used on the one hand as a table and on the other hand as a recreational sports device, comprises an outer body which is open on the top side, with a front wall arranged vertically, a rear wall opposite it and two side walls connecting the front wall and rear wall to each other. An inner body which can be moved relative to the outer body is arranged in the interior of the outer body and can be moved from a retracted position out of the outer body into a vertical end position by a first electrically actuatable lifting device.The piece of furniture further comprises a wall element accommodated in the inner body, which can be moved by a second electrically actuatable lifting device from a retracted position out of the inner body into a vertical end position. The wall element is configured to carry a dart board which can be fastened to it by connecting means such as a hook and loop tape or hook connection. The piece of furniture according to the invention further comprises a cover element which, in the retracted position of the inner body and wall element, at least partially covers the upper side of the outer body in a first closure position and can be used as a work plate in this closure position. The cover element can be pivoted into a second release position or moved in the vertical direction, in which it releases the access to the interior of the outer body.For moving the first and second lifting devices, an electrical actuating device is provided, e.g. one or more manually actuatable electrical switches, or an electrical actuating device which can be controlled by a remote control, for example via Bluetooth from a mobile device and is designed to move the first and second lifting devices in such a way that the inner body and the wall element are moved up and down preferably one after the other in the vertical direction, in such a way that the center of a dart plate fastened to the wall element, in the extended end position of the inner body and of the wall element, is at a clear distance of substantially 1.73 m with respect to the placement surface on which the outer body is supported.The invention has the advantage that the piece of furniture according to the invention can be used both for conventional work in the office as a table and can be remodeled in the shortest time, so to speak, to a dart game station in the pauses between the works, without a dart game having a dart plate and a correctly positioned ejection line having to be installed permanently for this purpose. This allows considerable saving of space, or the space available in an office can additionally be used for sporting activities within the shortest time.Further features of the invention are described in the dependent claims.In the drawings, there are shown: FIG. 1 a shows a schematic three-dimensional illustration of the piece of furniture according to the invention with the dart board retracted when used as table furniture, FIG. 1 bshows a schematic semi-transparent representation of the piece of furniture from FIG. 1 a, FIG. 2a shows a schematic three-dimensional representation of the inventive combination furniture item with the dart plate fully extended when used as a dart game device, FIG. 2 bshows a semi-transparent representation of the combination furniture item from FIG. 2 a, FIG. 3 ashows a schematic three-dimensional side view of the piece of furniture from FIG. 1 a, FIG. 3 bshows a semi-transparent representation of the piece of furniture in a side view, and FIG. 4 shows a schematic three-dimensional view of a further embodiment of the inventive piece of combination furniture, in which the table top is arranged fixedly on the upper side of the wall element.As is shown in FIGS. 1 to 4, a multifunctional piece of furniture 1 according to the invention comprises an outer body 2 which is open on the upper side and has a front wall 2 farranged upright, a rear wall 2 ropposing it, and two side walls 2 sconnecting the front wall 2 fand rear wall 2 rto one another. An inner body 6 is arranged in the interior of the outer body 2, which inner body can be moved relative to the outer body 2 by a first lifting device 4 from a retracted position shown in FIGS. 1 aand 1 binto a vertical end position shown in FIGS. 3 aand 3 b.The inner body 6 also accommodates a wall element 10 which can be moved by a second lifting device 8 in the vertical direction out of the inner body 6 from a retracted position (FIG. 1 b ) into a vertical end position (FIGS. 2 a, 3 aand 4 ). As can be seen in the illustration of FIG. 2 a, the wall element 10 is configured to receive a dart plate 12 which is fastened via fastening elements, not shown in more detail, to the inner wall of the wall element 10 which points toward the front side of the piece of furniture 1.The piece of furniture 1 according to the invention further comprises a cover element 14, or 114 which, in the retracted position of the inner body 6 and the wall element 10, in a first closed position, covers the upper side of the outer body 2 at least partially, but preferably completely, and thereby closes the opening 24 on the upper side of the outer body 2, so that the piece of furniture 1 can be used as a table, in particular as a desk or a work table. In this case, the cover element 14, 114 which is correspondingly designed on its upper side and is coated in particular with plastic or another suitable, mechanically insensitive material can be used as a work plate. In the closed position, the inner body 6 and the wall element 10 are inserted into one another in a completely nested manner, so that the upper edges of the inner body 6 are at the same height or below the upper edges of the outer body 2.As can be seen from the illustration of FIGS. 2 aand 2 b, the cover element, in contrast, releases access to the interior of the outer body 2 in a second release position, in which the cover element 14 is preferably pivoted away to the rear, or, according to a further embodiment of the invention, is alternatively arranged in a horizontally extending plane above the wall element, as is indicated in FIG. 4.The piece of combination furniture 1 according to the invention further comprises an electrical actuating device 16 which is configured to move the first and second lifting devices 4, 8 in such a way that the inner body 6 and the wall element 10 are preferably moved up and down one after the other in the vertical direction in such a way that the center 12 zof a dart plate 12 fastened to the wall element 10 is arranged at a vertical distance of 1.73 m in the extended end position of the inner body 6 and wall element 10 with respect to the placement surface 18, e.g. the floor on which the outer body 2 is preferably supported via four rollers.In the preferred embodiment of the invention, the first electrically actuatable lifting device 4 comprises a first and a second lifting column 4 a, 4 bwhich comprises a first fixed element connected to the outer body 2 and a second element which is vertically movable relative to the latter and is connected to the inner body 6, in particular an adjoining side wall 6 sof the inner body 6. In the same way, the second lifting device 8 comprises at least one, but preferably two further electrically actuatable lifting columns 8 a, 8 bwhich each have a fixed element coupled to the inner body 6 and a further movable element which is vertically displaceable relative to the latter and to which the wall element 10 is fastened.In the preferred embodiment of the invention shown in the figures, this preferably completely spans the rear side of the piece of furniture between the two second lifting columns 8 a, 8 b, so that arrows which fall from the dart plate or which accidentally strike laterally next to it cannot reach behind the piece of furniture 1. This makes it possible to clearly simplify the search for lost arrows even in the case of restricted space conditions and advantageously reduce the risk of damage to objects which are located on the rear side of the piece of furniture in the event of misses.The lifting columns used for moving the inner body 6 and also the conversion element 10, which lifting columns have an inner spindle drive driven by an electric drive motor, for example, are sufficiently known in the field of office furniture and serve, for example, for moving work surfaces of tables up and down by motor.In the preferred embodiment of the invention, the vertical travel paths of the first and / or second lifting device 4, 8 are preferably adjustable, e.g. by changing the position of a respective limit switch on the respective lifting column, so that the travel path of the second lifting device 8, in particular, in the end position is exactly adjusted so that the height of the center 12 zof the dart plate 12 exactly corresponds to the height of 1.73 m predetermined in the dartport. The actuating device 16 is preferably configured such that the travel path or travel paths of the first and / or second lifting device 4 / 8 can also be adjusted afterwards, e.g. if the height of the outer body 2 above the ground changes due to the type of floor covering used. Although this can also be done purely mechanically, for example via adjustable limit switches, this is preferably done via the control device which controls the position of the lifting devices 4 / 8.According to a further idea underlying the invention, a receiving space 20 is formed between the front wall 2f of the outer body 2 and the front wall 6f of the inner body 6 arranged adjacent thereto. This is configured to accommodate a distance specification device 30, with which a predefined horizontal distance of in particular 2.37 m between a discharge line 32 and the dart plate 12 along the placement surface 18 can be predefined.Although the distance specification device 30 can be formed, for example, by three plate elements accommodated telescopically on one another, in the preferred embodiment of the invention it preferably comprises a total of three planar partial elements 30 a, 30 b, 30 c, as is shown in FIGS. 2 a, 2 band 3 a. These are preferably designed as rectangular plates which have an edge length which allows them to be introduced from above with their longitudinal edges in front into the receiving space 20 and to be stowed in the receiving space 20 in a stacked form, as is indicated in the semi-transparent illustration of FIG. 1 b.The three plate-shaped flat partial elements 30 a, 30 band 30 cmay consist, for example, of foamed plastic material and preferably have interlocking coupling elements 34 aand complementary coupling elements 34 bwhich may be connected to one another in a form-fitting manner in the manner of puzzle pieces to form a coherent planar mat which may be arranged on the placement surface 18. As is indicated in FIGS. 2 aand 3 b, a stop 36 a couplable to the outer body 2 is arranged at the first end of the mat and a strip 38 defining the ejection line 32 is arranged at the second end of the mat.In the area of the bottom of the outer body 2, a counterstop 36b extending downward from the latter, i.e. in the downward direction toward the placement surface 18, and two lateral stop surfaces 36s are arranged, against which the stop 36a of the distance specification device 30 can be placed after the latter has been assembled to form a mat and pushed under the outer body 2. The stop 36 aon the mat and the counterstop 36 bon the outer body as well as the lateral stop surfaces 36 scooperating with the stop 36 ain the lateral direction are configured to limit a lateral and / or longitudinal movement of the distance specification device 30, i.e. of the assembled mat. The arrangement of the counterstop 36 band of the lateral stop surfaces under the bottom of the outer body has the advantage that they are not visible from the outside during the use of the piece of furniture 1 as a working or meeting table, so that the table is perceived as such without any visual restrictions.In order to avoid disadvantages during the displacement or movement of the furniture item 1 according to the invention on the supporting surface 18 or during the transport thereof, the counterstop 36 ain the last-described embodiment of the invention comprises a lateral stop plate 36 bextending in the lateral direction of the outer body 2. The two lateral stops 36s, in contrast, are designed as two side plates 36s arranged orthogonally to the latter, which can be inserted into the base 2b of the outer body 2 from the inside through one or more preferably slot-shaped openings formed in the base 2b of the outer body 2 for each of the plates 36b, 36s. The lateral stop plate of the counterstop 36 band the two side plates of the lateral stops 36 sarranged orthogonally thereto can be connected to form a coherent component which is inserted from the inside into the corresponding opening in the base plate 2 bof the outer body 2 and which preferably remains in the base plate 2 bduring the transport of the furniture item 1 according to the invention in the interior of the outer body 2 after being pulled out of the relevant opening. In order to gain access to the openings in the base plate 2 band the stop plates 36 b, 36 sfrom the interior of the outer body 2, the rear wall 2 rof the outer body 2 is advantageously formed in multiple parts, in particular 3 parts with a removable central part (not shown), which can preferably be closed off. The removable middle part has the advantage that the assembly, installation and revision of the mechanical and electrical components, such as the lifting devices, electrical components and supply lines, in the interior of the outer body are considerably facilitated.According to a further idea underlying the invention, the receiving space 20 can be covered on its upper side by a flap 22 which can be pivoted separately from the cover element 14 and which can be seen, for example, in the open position in FIG. 2 a. In the closed position (not shown), this covers the opening 24 on the upper side of the receiving space 20 and, when the inner body 6 is moved into the first retracted position (FIGS. 1 a, 1 b), is pivoted away from the front side of the outer body 2 into an open vertical position, which is illustrated in the side view in FIG. 3 b, via a guide curve 26 formed on the inner side of the front wall 2 fof the outer body 2. The flap 22 serves to close the receiving space 20 after the partial elements 30 a- 30 care removed, so that arrows which rebound from the dart plate 12 cannot fall into the receiving space 20. The guide curve 26, on the other hand, ensures that the flap 22, after opening for removing the flat partial elements 30 a, 30 band 30 cand subsequent closing, is automatically opened again during the game operation and moved into the vertical position shown in FIG. 3 b. As a result, when the inner body 6 is moved down, the flap is prevented from colliding with the retaining plate 50 shown in FIGS. 2 aand 3 a, 3 b, to which a digital input device such as a tablet, which is required for the game operation, can be fastened. As can be seen from the illustration of FIG. 3 b, the retaining plate 50 would otherwise collide with the flap 22 when the inner body 6 is moved down and would be damaged if the latter is in the closed horizontal position (not illustrated) in order to cover the receiving space 20 during the game operation.In order to improve the visibility of the dart screen 12 for the players during the game operation, an annular illumination device 40 is preferably arranged on the side of the movable wall element 10 facing the front side of the outer body 2, said illumination device being arranged concentrically to the dart screen 12 received on the wall element 10, by means of which illumination device the dart screen 12 is illuminated in the extended position of the wall element 10. In this embodiment of the invention, an electrical switch, not shown, is preferably provided, which automatically activates the lighting device 40 when the wall element 10 and / or the inner body 6 is moved into the extended end position.According to a further idea underlying the invention, the cover element 14 is pivoted rearward away from the front wall of the outer body 2 via hinges 11 received on the rear wall 2 ror the side walls 2 sof the outer body 2 into a substantially vertical open position, in which access to the interior of the outer body 2 is completely released. The hinges 11 indicated in FIG. 3 bare configured for this purpose in such a way that the entire cover element 14 in the pivoted-open position is arranged offset to the latter in a plane running parallel to the rear wall 2 rof the outer body 2, such that the cover element 14 can extend beyond the rear wall 2 rof the outer body 2 on the rear side thereof without colliding with the rear wall. This embodiment of the invention allows the cover element 14 to extend on all sides beyond the standing walls of the outer carcass 2, for example by 200 mm or more, in order to provide the necessary leg clearance when the piece of furniture is used as a seat work station.According to a further idea underlying the invention, it can be provided that the wall element 10 contacts the cover element 14 on its underside when it is moved out of the inner body 6 and pushes it out of the horizontal closure position into the vertical open position. In this case, the wall element 10 is first moved by the second lifting device 8 out of the inner body 6 in the vertical direction, while the inner body 6 remains in the retracted position in the outer body 2. The raising of the wall element 10 when the inner carcass 6 is retracted results in the advantage that the raising force required for raising the cover element 14 is smaller, since the point of application of the raising force extends further away from the hinges towards the front side of the piece of furniture.According to a further embodiment of the invention illustrated in FIG. 4, the cover element 114 is arranged on the upper side of the wall element in a horizontal plane fixed to the wall element and is movable together with the wall element in the vertical direction in such a way that the cover element 114 in the lower end position lies completely on the upper side of the outer body 2 and covers the latter. This embodiment of the invention has the advantage that no hinges 11 and, if appropriate, retaining straps (not shown) are required, with which the cover element 114 has to be pivoted beyond the plane of the rear wall 2 rinto the vertical position and retained therein.List of reference characters1 Multifunctional piece of furniture according to the invention 2 outer body 2 rback wall outer wall 2 ffront wall 2 sside walls 2 bbase of outer body 4 first lifting device 4 a, 4 blift columns of first lifting device 6 inner body 6 sside walls of inner body 8 second lifting device 8 a, 8 blift columns of the second lifting device 10, movable wall element 11 hinge 12 dart pane 12 zcentre of the dart pane / bulls eye 14 cover element / table top 16 electrical actuating device 18 placement surface / base 20 receiving space 22 pivotable flap 24 opening at the top side of the receiving space 26 guide cam 30 distance specification device / mat 30 afirst partial element 30 bsecond partial element 30 cthird partial element 32 ejection line 34 acoupling elements 34 bcomplementary coupling elements 36 astop at distance specification device 36 bcomplement stop 36 slateral stop surfaces at the bottom side of the outer body 38 ledge, the ejection line defines 40 annular lighting device around dart pane 50 holding plate for digital input device / tablet 114 cover element of the further embodiment of FIG. 4
