Definitions

  • the invention relates to a table with a table frame, a table top movably mounted on the table frame and a device for adjusting the height of the table top relative to the table frame on at least one of its edges, at least one abutment being fixedly attached to the table frame below the table top.
  • Tables whose table top is adjustable in height and / or inclination are known in many embodiments. Tables with a height-adjustable table top make it possible to set a working height of the table top that is convenient for the person using the table, while tables with a tiltable table top offer the possibility of tilting a normally horizontal table top into a more convenient position for writing or drawing . If such tables do not have relatively complex, mechanical gears adjusting devices for the table top, locking devices in the form of bars, pens and the like are provided, the handling of which is relatively cumbersome, which often prevents the user from taking advantage of the proposed adjustment possibility.
  • a table with an adjustable table frame in which a table top movably mounted on the table frame can be adjusted with a device for adjusting the height of the table top relative to the table frame. This takes place at least on one of its edges and with at least one abutment for the table top which is firmly attached to the table frame.
  • the invention is therefore based on the object of designing a table of the type mentioned at the outset in such a way that the adjustment of the table top is not a problem, but without the device for adjusting the height or the inclination of the table top requiring great effort, in particular comprising complicated gears . At the same time, a stable fixation of the table top in the selected position should be ensured.
  • the abutment is assigned a wedge-shaped intermediate piece which is displaceably mounted in the opening direction of its angle substantially parallel to the table top and can be inserted more or less between the abutment and the table top, so that the position of the Intermediate piece determines the distance of the table top from the abutment and thus also the position of the table top relative to the table frame.
  • the table top is accordingly held in the selected position in that it is held by a wedge-shaped intermediate piece at a distance determined by the position of the intermediate piece from an abutment fixedly attached to the table frame. It can Take the intermediate piece a position in which the table top lies directly against the abutment, the distance of the table top from the abutment determined by the intermediate piece is therefore zero. In this case, the abutment defines the lowest position of the table top.
  • the table is therefore extremely easy to use.
  • the intermediate piece can either be attached to the table frame or the table top and there are many options for storing such an intermediate piece so that it can be inserted between the table top and the abutment or removed from the area between the table top and the abutment. In the simplest case, it is sufficient to attach the wedge-shaped intermediate piece to the end of a push rod which extends to the edge of the table top, so that it is easily possible for the user to move the intermediate piece by means of the push rod.
  • Such push rods would also make it possible to connect several wedge-shaped intermediate pieces with one another so that they can be moved together, which is particularly desirable when a parallel raising or lowering of the table top is to be possible by means of abutments and intermediate pieces arranged on several edges of the table top.
  • a table designed according to the invention can have a table top which can optionally be brought into one of two defined positions, namely a lower position in which the table top lies directly against the abutment, and in an upper position in which the wedge-shaped intermediate piece is completely inserted between the abutment and the table top.
  • a wedge offers the possibility of changing the distance of the table top in small steps or even continuously by changing the position of the wedge in relation to the abutment.
  • a preferred embodiment of the invention provides that the wedge-shaped intermediate piece has a first wedge surface parallel to its direction of displacement and a second wedge surface arranged obliquely thereto, and the second wedge surface rests on an inclined surface parallel to it in at least one defined position of the table top.
  • the first wedge surface forms a flat contact surface on a counter surface parallel to the direction of displacement, while the second wedge surface also comes into contact with a large area with an inclined surface provided for this purpose and parallel to the wedge surface.
  • the second wedge surface and the one next to it need it Sloping surface not necessarily to be flat, but they can advantageously be designed as cylindrical surfaces with generators parallel to the legs of the wedge angle, so that they produce a positive engagement transversely to the direction of displacement of the intermediate piece, which offers the possibility of securing the table top against one To give up the direction of movement of the intermediate piece in the vertical direction on the table frame.
  • the wedge surface and the inclined surface lying thereon can preferably be designed as circular cylindrical surfaces with essentially the same radius.
  • a preferred field of application of the invention can be found in tables which have a table top which is adjustable in inclination.
  • the table top is preferably pivotally mounted in the area of its rear edge and its inclination can be changed by adjusting its height in the area of the front edge.
  • a disadvantage of the previously known tables of this type was that the table top articulated in the region of its rear edge was supported on its front edge, which had the prerequisite that the table frame had parts reaching into the region of the front table edge, on which the Support can take place.
  • modern tables such as those used in particular as work tables in offices, often have a table frame which essentially consists only of two side parts provided with feet and a support connecting the side parts, which is arranged in the region of the rear edge of the table top.
  • a particular advantage of the invention is that it can also be implemented with such table frames. So is in a preferred embodiment of a table, the Table top is pivotally mounted in the area of its rear edge, the abutment is arranged near the rear edge of the table top. This abutment has an inclined surface against which the table top rests in its lowest position. From this lowest position, the table top can then be raised to the horizontal position by inserting the wedge-shaped intermediate piece between the abutment and the table top.
  • the push rod is guided in a bearing block attached to the underside of the table top. It carries a handle at its end opposite the intermediate piece and is surrounded by a helical compression spring which is supported on the one hand on the bearing block and on the other hand on the intermediate piece.
  • the table according to the invention also offers such a possibility, if, in a further embodiment of the invention, at least one hollow support extending perpendicularly to its rear edge is attached to the underside of the table top, the abutment protrudes into the rear end of the hollow support and the push rod is mounted with the intermediate piece within the hollow support and is movable in its longitudinal direction.
  • the stop with the hollow support can then be attached to a corresponding spar of the table frame, so that there is the possibility of attaching a table top corresponding to the respective customer request to such a hollow support.
  • the hollow beam can be connected in an especially advantageous manner to the stop protruding into its rear end.
  • a particularly simple and at the same time particularly stable design of the adjusting device can be achieved in that at least one wedge-shaped intermediate piece in the longitudinal direction of the Carrier is slidably arranged and on the underside of the table top a wedge piece associated with the intermediate piece and complementary to the intermediate piece is attached with an inclined surface inclined to the table surface against which the intermediate piece bears with its second wedge surface.
  • the table top is supported directly on the height-adjustable edge on a stable support, so that the table top is able to take up very high loads without special effort having to be made with regard to the stability of the table frame, as is more self-supporting in the application Arms to hold the table top is necessary.
  • the arrangement of a single intermediate piece between the support and the table top may be sufficient, but several such intermediate pieces may also be necessary.
  • two intermediate pieces are arranged at a distance from one another in the region of the height-adjustable edge of the table top, each of which is assigned a complementary wedge piece and which are connected to one another by a push rod extending parallel to the edge of the table top.
  • the connecting rod connecting the intermediate pieces is provided with a radially projecting handle and the support of the table frame, on which the intermediate pieces are arranged displaceably, several spaced apart, has the locking positions of the wedge-shaped intermediate pieces defining recesses into which the handle can be inserted.
  • the table frame shown in Fig. 1 has two side parts, each consisting of an elongated foot 1 and a column 2, which protrudes from the foot 1 near one of its ends.
  • the columns 2 are each formed by a channel-like profile, which allows the insertion of electrical lines and the like and is closed from the outside by a hood 3.
  • the two columns 2 are connected to each other by a longitudinal beam 4, which is also designed as a hollow profile.
  • Two stops 5 are attached to the longitudinal beam 4 at a distance from one another, on which hollow beams 6 are attached.
  • the hollow beams 6 are essentially horizontally from the side member 4 towards the same side, after which the feet 1 protrude beyond the column 2. They are used to fasten a table top 7, as indicated by dash-dotted lines in FIG. 1.
  • the abutments 5 consist of a profile part which is essentially U-shaped in cross section and which has a projecting tab 51 at one end, which engages in a slot 41 in the side member and is fastened to the side member.
  • the hollow supports 6 are pushed onto the abutments 5 and are connected to one another in an articulated manner by means of a bolt 8 passing through the lateral sections of the U-shaped profile and the lateral walls of the hollow supports 6.
  • the hollow beams 6 each consist of an upper plate 61, on the underside of which a type of hood 62 is fastened, the height of which decreases from the end of the hollow beam 6 facing the longitudinal beam 4 to the other end.
  • the abutments 5 each engage in the hood 62 of the associated hollow beam. They also taper in the direction of the end protruding from the longitudinal beam 4, more so than the hood 62, so that the hollow beam 6 can be pivoted by a certain angle relative to the abutment 5 about the axis formed by the bolt 8.
  • the plate 61 of the hollow support 6 In its upper position, which corresponds to the horizontal position of the table top 7, the plate 61 of the hollow support 6 forms an angle with the transverse web 52 of the abutment 5 forming a stop surface, which in the illustrated embodiment is arranged by a wedge-shaped intermediate piece 9 arranged inside the hood 62 is filled out.
  • This intermediate piece 9 is attached to the end of a rod 91 which is slidably mounted in a bearing block 92 fastened within the hood 62 on the underside of the plate 61.
  • a helical compression spring 93 which strives to hold the intermediate piece 9 in the area between the crosspiece 52 of the abutment 5 and the plate 61 carrying the table top 7.
  • the free end of the rod 91 protrudes from the hood 62 and is provided there with a button 94 serving as a handle.
  • the table top in the drawn-out position in FIG. 2 of the hollow support 6 is supported via the intermediate piece 9 on the crossbar 52 of the abutment 5 and is thus held securely in the horizontal position.
  • the intermediate piece 9 is pulled out of the area between the table top 7 and the abutment 5 in the opening direction of its wedge angle by pulling the button 94, the hollow support 6 with the table top 7 can pivot down into the position shown in broken lines in FIG. 2 in which position the hollow support 6 with its plate 61 rests directly against the stop surface formed by the crosspiece 52 of the abutment 5.
  • the inclination of the table top is approximately 10%.
  • the table top 7 If the table top 7 is to be brought back into a higher position, it is sufficient to raise the table top 7 slightly at its front edge. It then enters the wedge-shaped intermediate piece 9 under the force of the helical compression spring 93 into the space between the abutment 5 and the table top 7 (cross piece 52 and plate 61), to the extent that the space created by lifting the table top allows.
  • the force of the helical compression spring 93 is not sufficient to bring the hollow supports 6 with the table top 7 into the horizontal position beyond the position selected by lifting, while on the other hand between the surfaces of the wedge-shaped intermediate piece and the Transverse web 52 of the abutment 5 or the plate 61 of the hollow support 6 is sufficiently high to prevent the wedge-shaped intermediate piece 9 from being pressed outwards by the weight of the table top 7. It is therefore possible to bring the table top into any desired position by simply lifting and locking it without additional measures.
  • the front edge of the table top can be lowered just as easily by pulling out the intermediate pieces 9 from the area between the crosspiece 52 of the abutment 5 and the table top 7 by the desired amount.
  • the table shown in FIGS. 4 to 7 has two side parts 101, 102 which are connected to one another by two longitudinal members 103, 104 to form a stable frame, between the side parts 101, 102 of which a table top 105 is arranged.
  • the table top 105 connects with its rear edge to the one longitudinal beam 103 and is connected to this longitudinal beam in an articulated manner.
  • This articulated connection can be made by means of hinges but can also consist only in a simple support of the rear edge of the table top 105 on a contact surface attached to the longitudinal beam 103.
  • the other longitudinal beam 104 is located in the front area of the table top 105 and is arranged below the table top, so that it is not visible in FIG. 4.
  • the carrier 104 arranged at the front edge of the table top 105 is designed as an upwardly open hollow profile in which two blocks 106 belonging to an adjusting device are slidably mounted.
  • Two angle rails 141, 142 which are on the side walls of the hollow support, are used to support these blocks 106 104 are fastened in such a way that their webs 143, 144 projecting from the side walls face each other in a plane parallel to the axis of the carrier 104. These webs engage in corresponding slots 161, 162 on the side surfaces of the blocks 106, so that these webs form slide rails for the blocks.
  • the two blocks 106 are connected to one another by a push rod 107, which has a radially protruding handle 170 in the area of its center, which penetrates a slot 145, which is provided in the side wall of the carrier 104 facing the edge of the table top 105.
  • This slot 145 has three spaced-apart recesses 146, into which the handle 171 projecting radially from the push rod 107 can be inserted by pivoting the push rod.
  • These three cutouts 146 define discrete locking positions for the blocks 106 which can be displaced along the carrier 104 by means of the push rod 107.
  • the blocks 106 form wedge-shaped intermediate pieces with which wedge pieces 108 fastened on the underside of the table top 105 interact.
  • These wedge pieces have a flat surface 181, with which they rest on the underside of the table top 105, and an inclined surface 182 inclined to the table surface, which in the exemplary embodiment shown is formed by a circular cylindrical surface which has an axis which is inclined to the flat contact surface 181.
  • This inclined surface 182 runs parallel to a cylindrical wedge surface 163, which is formed by a corresponding recess in the block 106.
  • the arrangement is such that the inclined surfaces 182, which are located on the wedge pieces 108 attached to the underside of the table surface 105, bear against the wedge surfaces 163 of the blocks 106.
  • these blocks 106 form wedge-shaped intermediate pieces which are connected to a first wedge surface 164 on the bottom of the carrier 104 or with the parallel grooves 161, 162 on the angle rails 141, 142 fastened in the carrier 104 are guided in the direction of displacement of the blocks 106, while on the second wedge surfaces 163 the tabletop 105 with the interposition of the wedge pieces 108 comes to the plant. Accordingly, the table top 105 is supported on the carrier 104 with the interposition of the wedge pieces 108 and the intermediate pieces 106, the position of the intermediate pieces 106 determining the distance of the table top 105 from the carrier 104.
  • the intermediate pieces 106 can be shifted to the right in the drawing so that the table top 105 comes to rest directly on the upper side of the carrier 104. From this position, the table top 105 is raised when the intermediate pieces formed by the blocks 106 are moved to the left by means of the handle 171 attached to the push rod 107. Before the uppermost position shown in FIG. 6 is reached, the handle 171 passes through a central recess 146 at the edge of the slot 145, through which a central locking position for the intermediate pieces 106 and thus also for the table top 105 is defined. It goes without saying that a larger number of such locking positions could also be provided. Here too, after lifting the table top at the front edge, the intermediate pieces can be adjusted by actuating push rod 107 on handle 171 without great effort.
  • the invention is not limited to the exemplary embodiments shown, but deviations are possible without leaving the scope of the invention.
  • Intermediate table top arranged to be displaceable perpendicularly to this front edge, and it would also be conceivable to arrange wedge-shaped intermediate pieces on at least two parallel edges of the table top and to connect them to one another such that the simultaneous adjustment of all intermediate pieces enables the table top to be raised or lowered in parallel.
  • the wedge surfaces of the intermediate piece and of the wedge piece interacting therewith do not necessarily have to be rectilinear in the direction of displacement, but could have a fine gradation which forms a detent preventing an undesired displacement of the intermediate pieces.
  • adjustable intermediate pieces and / or the associated abutments can be attached not only to the side members of the table frame, but also to the side parts thereof. Accordingly, a variety of modifications will be apparent to those skilled in the art, all of which are within the scope of the invention as defined by the claims.
