Definitions

  • the invention relates to a work table, in particular an office table, with a rectangular table top which is supported by a table frame and which is adjustable in height and inclination.
  • a work table with a table top is known, which is supported by four vertical columns in guides of the table legs can be raised and lowered.
  • the columns have snap-in receptacles distributed in the longitudinal direction and are adjustable by means of snap-in elements attached to the guides.
  • the columns are connected to each other by a lever linkage with which the columns can be rotated and the snap-in connections can be canceled and restored after the columns have been adjusted. Since the columns can only be rotated but not tilted to the table top, the height can only be adjusted in a horizontal position. Therefore, all four columns must be turned and unlocked at the same time. This requires a synchronous control device for all columns, which is correspondingly complex and difficult to operate manually. However, since the adjustment can be carried out manually, there are none complex drive devices, such as adjusting spindles, actuators and the like.
  • the table top As the DE-PS 49 796 shows, it is also known to make the table top adjustable in height and inclination.
  • the table top rests on an adjustable column via a ball joint, which is designed as a rack and is adjustable by means of a gear drive.
  • the table top is supported by four adjustable columns with adjustment slots on locking screws on the table legs. If the position of the table top changes, the locking screws must be loosened and tightened again after the rack has been adjusted with the table top.
  • this requires complex and cumbersome control devices.
  • the table top carries a bearing unit with a frame support plate running parallel to the associated narrow side of the table top on the narrow sides, in that a pair of links are articulated in parallel on each frame support plate as table legs so that the lower ends the handlebars are each articulated on a foot parallel to the associated and directed towards the operating side of the table top and that at least one handlebar of each pair is assigned a locking device by means of which the set inclination of the handlebars directed towards the operating side of the table top can be locked.
  • the table frame only comprises the four handlebars with the two feet. After releasing the locking devices, the height of the table top can be changed simply by pivoting the handlebars. The newly set inclination of the handlebars is then locked with the locking devices.
  • one embodiment provides that the feet carry bearing plates in the end regions facing away from the operating side of the table top, to which the handlebars are articulated by means of bearing bolts, and that the bearing units are off-center on the narrow sides of the table top and to the rear of the table top are attached offset.
  • the possibility of changing the inclination of the table top can be achieved in a simple manner in that the table top is connected to a respective support plate in the area of the bearing units and that the support plates are each rotatably mounted on the associated frame support plate by means of a bearing element.
  • one embodiment provides that the support plates can be fixed non-rotatably with respect to the frame support plates by means of locking screws, locking pins and the like, the change in inclination being able to take place continuously or in predetermined steps.
  • a solution to the change in predetermined stages is provided, which is characterized in that the locking pins, which are adjustably guided in the support plates, can be brought into engagement and out of engagement with locking receptacles of the frame support plates by means of manually operable lever linkages.
  • an embodiment is advantageous, which is characterized in that the table top is mounted on a cross member, which is non-rotatably and firmly connected to the support plates of the bearing units with both ends, since this configuration is free for the construction of the table top lets and also include glass plates and the like.
  • a sufficient torsional rigidity of the table frame designed in this way is ensured in that the two frame support plates are rigidly connected to one another by means of a frame cross member. According to one embodiment, this can be achieved in that the frame cross member designed as a hollow profile section is inserted into corresponding openings in the frame support plates and welded to them.
  • a shapely transition between the table top and the bearing units is obtained according to one embodiment in that the long sides of the table top are provided with end profiles attached to longitudinal members and that on the End profiles inner covers are attached in the area of the bearing units, which cover the support plates and the frame support plates.
  • the storage units can be exploited in a simple manner for the attachment of additional parts that carriers for additional parts to be arranged above the table top, such as table lamps, shelves and the like, are attached to the outer sides of the frame support plates.
  • the work and / or storage area of the work table can be increased in a simple manner in that table additional plates can be or are connected in a horizontal position to the outer sides of the frame support plates.
  • a sleeve is connected to each support plate rotatably mounted on the frame support plate, which is arranged on the outside of the frame support plate and serves as a plug-in receptacle for a plug-in extension of the outer cover and / or as a bearing element for limited pivotable supports for additional parts , then not only the outer cover can be easily attached to the storage unit.
  • Carriers for additional parts can also be attached to the storage unit in such a way that they can be pivoted to a limited extent.
  • an embodiment has proven to be particularly simple, which is characterized in that the lower ends of the handlebars as a locking device for the handlebars of a pair the sides facing each other are connected with overlapping plates, that the plates in the overlapping areas are provided with arcuate elongated holes for receiving a locking screw, the radii of the elongated holes being related to the respective joint axes of the handlebars and that the locking screws for locking the Position of the plates and thus the handlebar can be screwed into a threaded hole of an abutment plate connected to the associated foot.
  • the design is such that the handlebars consist of square tube sections which are firmly connected at their ends to bearing eyes, that the bearing eyes facing the bearing units are connected to the associated frame support plate by means of screws and that the bearing eyes facing the feet can be rotated in cover plates by means of bearing bolts are stored, which cover the plates and the abutment plate.
  • a stylish finish is achieved in that the square tube sections of the handlebars are covered by cladding profiles.
  • Fig. 1 shows schematically the structure of the work table according to the invention.
  • Bearing units 11 are attached on both narrow sides of the rectangular table top 10, specifically off-center and offset toward the rear of the table top 10.
  • two parallel arms 14 and 17 extend as table legs, which are connected to the bearing unit 11 in an articulated manner, as shown by the joint axes 15 and 18.
  • the table top 10 is also pivotally attached to the bearing units 11 in order to be able to be adjusted to different inclinations, as can be seen from the positions designated 10 ′ and 10 ′′ and the horizontal pivot axis 13.
  • the lower ends of the links 14 and 17 are at one Foot 20 articulated to the end of the foot 20 facing away from the operating side, which runs parallel to the associated narrow side of the table top 10 and to Operating side of the same is directed.
  • the links 14 and 17 assume an inclination towards the operating side of the table top 10, which can assume an acute angle of approximately 65 ° to 85 °.
  • the lower pivot axes of the links 14 and 17 are designated.
  • the cover plates 21 can cover the articulation points with the parts required for this. In the smallest inclination of the handlebars 14 and 17 there is always so much space under the table top 10 that an occasional furniture 30 can be accommodated.
  • the links 14 and 17 of the two narrow sides of the table top 10 are stiffened by means of a frame cross member 22, as will be shown.
  • the additional plate 27 and the support 23 for the table lamp 24 are attached to the right-hand storage unit 11.
  • the table top 10 can have a storage attachment 28 and inserted glass plates 25 and 26, as the top view according to FIG. 3 shows.
  • the additional plate 27 and the support 29 of the storage plate 31 are attached to the left bearing unit 11.
  • the storage plate 31 has two recessed grooves 33 into which the brackets 32 can be inserted.
  • the links 14 and 17 consist of square tube sections 34 and 38 which are fixedly connected to the bearing eyes 35 and 39 at the lower ends.
  • the cladding profiles 37 and 41 cover the square tube sections 34 and 38.
  • the bearing bolts 36 and 40 which are inserted through the bearing eyes 35 and 39, are mounted in the bearing plates 48 and 50.
  • the bearing plates 48 and 50 are firmly connected to the base plate 52 of the foot 20 and can also take over the function of the cover plates 21 mentioned at the outset.
  • the links 14 and 17 carry the overlapping plates 43 and 45 on the sides facing one another. In the overlapping regions, the plates 43 and 45 are provided with arcuate elongated holes 44 and 46 through which the locking screw 42 is guided. The radii of the elongated holes 44 and 46 are related to the pivot axes 16 and 19 of the links 14 and 17 and are coordinated with the pivot angle thereof.
  • the locking screw 42 is screwed into the threaded hole of the abutment plate 51, which is also firmly connected to the base plate 52 of the foot 20. If the locking screw 42 is loosened, the links 14 and 17 can be adjusted in the swivel range predetermined by the elongated holes 44 and 46.
  • the two pairs of links of the table top 10 are connected in the same way with a foot 20 in an articulated and lockable manner.
  • the bearing plate 48 has a bore 49 which allows access to the locking screw 42.
  • Each bearing unit 11 has a frame support plate 62 with an opening through which the frame cross member 22 is inserted.
  • the frame support plates 62 are firmly connected to the frame cross member 22, for example welded.
  • the table top 10 is built on the cross member 56, which is non-rotatably connected at both ends to a support plate 58, as the connecting part 57 of FIG. 8 indicates.
  • the support plate 58 has an approach on which a bearing element 61 is pushed on. This bearing element 61 is inserted into a receptacle of the frame support plate 62 and produces a rotary bearing between the frame support plate 62 and the support plate 58.
  • the support plate 58 and the bearing element 61 are held by the sleeve 60, which is connected to the shoulder of the support plate 58 by means of the screw 59. Therefore, since the support plate 58 and the sleeve 60 are attached to the frame support plate 62 with the bearing element 61 with play, the table top 10 can be freely pivoted on the frame support plates 62 in order to be adjusted to different inclinations.
  • the set inclination can be locked by means of locking screws, each of which braces the associated support plate 58 and the associated frame support plate 62.
  • a step change in the inclination of the table top 10 can also be achieved with the aid of adjustable locking pins.
  • the locking pins which are adjustable by means of manually operable lever linkages arranged on the underside of the table top 10, are adjustably mounted in the support plates 58 and can be brought into and out of engagement with locking receptacles in the frame support plates 62, specifically via the lever linkages.
  • the long sides of the table top 10 are closed by end profiles 54 which are fastened on side members 53.
  • the inner cover 55 is attached to the end profiles 54 and covers the support plate 58, the bearing element 61 and the frame support plate 62 from the side facing the table plate 10.
  • the carrier 23 for an additional part can be screwed onto the outside of the frame carrier plate 62 by means of screws 63.
  • the openings 67 in the support 23 designed as a hollow profile section allow access to the screws 63.
  • the support 23 or 29 can also be connected in various angular positions to the frame support plate 62, which then carries correspondingly distributed threaded receptacles.
  • the mask 64 covers the slot between the inner cover 55 and the outer cover 65 in the region of the carrier 23 led out of the storage unit 11.
  • the outer cover 65 carries a sleeve-shaped extension 66, which is inserted as a connector into the sleeve 60 in order to connect the outer cover 65 to the bearing unit 11.
  • the carrier 23 or 29, if it is provided with a corresponding bearing eye, can also be pivotally mounted on the sleeve 60.
  • the covers 55 and 65 leave a gap 74 which allows the pivoting movement of the carrier 23.
  • the mask 64 can cover the gap 74.
  • the additional plate 27 can also be attached, which can also be inserted with a part into the frame cross member 22 to prevent rotation.
  • the outer cover 65 then has a corresponding shape with recesses.
  • the hinge axes 15 and 18 of the links 14 and 17 are formed by the screws 69 and 71, which are guided through the upper bearing eyes 68 and 70 of the links 14 and 17 and screwed to the frame support plate 62.
  • These screws 69 and 71 are also easy to loosen when changing the height of the table top 10, but without breaking the connection to the frame support plate 62, and after setting and locking the handlebars 14 and 17 in a new inclination to tighten again. This increases the rigidity of the table frame designed in this way.
  • the frame support plate 62 is formed between the links 14 and 17 with the wall parts 72 and 73 so that these wall parts 72 and 73 can also define the end positions of the links 14 and 17 as stops.
