Definitions

  • the invention relates to a fitting for a worktable with a height-adjustable worktop that is variable in inclination.
  • fittings are also known which only allow a change in the inclination of the worktop of a work table, such as the DE-GM 80 25 650 and the DE-GM 81 08 834 show.
  • the stands are designed as tubular sections, that the cross member is a U-section section open at the top, the upper side of which is by means of a deck plate is lockable and that the booms are square tube sections. With the cover plate removed, the drivable shaft with the bevel gears can be easily installed in the crossmember.
  • the support frame is composed of two side members and two cross members, that the support frame is rotatably mounted on two mounting brackets, which are connected to the free ends of the arms and that the support frame is supported on one of the arms by means of a gas spring.
  • the pivoting movement of the worktop is then not hindered by the cantilevers if it is provided that the bearing brackets end over the free ends of the cantilevers and are connected to the supporting frame by means of screws as bearing elements, and that the cantilevers in the area of the stands on the top corresponding support bearings for have the support frame.
  • the rotary bearing of the adjusting spindles and the attachment of the bevel gears are solved according to one embodiment so that the adjusting spindles are supported at the upper end with a bearing section in ball bearings, which are supported on bearing plates fixed to the stand and that the bearing section through the bearing plate and rotatably carries the bevel gear.
  • the storage, as well as the drive of the drivable shaft in the cross member and their coupling with the adjusting spindles take place according to an embodiment in such a way that the drivable shaft is rotatably mounted in bearing plates which are fixed in the interior of the cross member that the ends of the shaft the bevel gears wear which are in engagement with the bevel gears of the adjusting spindles and that the shaft carries a further bevel gear which is in engagement with a bevel gear arranged on a drive shaft which can be rotated by means of a crank.
  • the drive shaft consists of two telescopically displaceable parts which are rotatably coupled to one another and arranged along a boom, and that a bracket is attached to the free end of this boom, which non-rotatably holds the drive shaft in an inserted position.
  • the crank can be fixed in a horizontal storage position if the design is such that the crank can be fixed non-rotatably in the horizontal position with a connector to the drive shaft between the bracket. The crank then does not protrude into the space under the worktop, so that there is sufficient freedom of movement for the person sitting at the worktable. In addition, the set height of the worktop is also locked.
  • the adjusting nuts are fixed in the upper ends of the adjusting sleeves designed as tubular sections and that the fastening angles with one leg with the lower ones protruding from the stands Ends of the adjusting sleeves are firmly connected.
  • the arms 13 and 14 are attached, which are directed perpendicular to the cross member 10 and horizontally.
  • mounting brackets 17 and 18 are attached, on which a support frame formed from the two longitudinal members 39 and 40 and the two cross members 41 and 42 is pivotally mounted. The pivot axis is formed by screws 43 which are guided through the mounting brackets 17 and 18 and screwed into the support frame.
  • the bearing tabs 17 and 18 protrude above and in the area over the top of the arms 13 and 14 the stands 11 and 12 support the arms 13 and 14 on the upper side support bearings 15 and 16, so that in the storage position the support frame on which the worktop is fastened assumes a horizontal starting position.
  • the set inclination of the support frame is maintained by means of a gas spring 37 which is fastened to a bolt 19 and a bearing block 38.
  • the bolt 19 protrudes on the inside of the boom 13 and receives a suspension eye of the gas spring, which is attached to the cylinder of the gas spring 37.
  • the piston rod of the gas spring is suspended on the bearing block 38, which is fastened on the inside of the cross member 41, in the area of the rear longitudinal member 40.
  • the handle frame 44 can be pivoted with the handle 44, the gas spring 37 maintaining any set inclination.
  • An additional lock can also be actuated with the handle 44.
  • the stands 11 and 12 receive an adjusting spindle 57, which, as shown in FIG. 3, is rotatably supported by a bearing section 56, but is axially immovable in the stand 11 and 12, respectively is.
  • the storage takes place in the bearing plate 61 on which the ball bearing 60 is supported.
  • the part of the bearing section 56 protruding from the bearing plate 61 carries the bevel gear 55 in a rotationally fixed manner.
  • the adjusting spindle 57 is adjustable in an adjusting nut 59 which is fixed in the upper end of the adjusting sleeve 58.
  • the lower end of the adjusting sleeve 22 or 58 protrudes from the stand 11 or 12 and is fixedly connected to one leg of a mounting bracket 20 or 27, as shown in FIG. 1.
  • the fixing can take place by means of a screw 21 or 28 which is screwed into a thread receptacle in the closed end face of the adjusting sleeve 22 or 58.
  • the adjusting sleeve 22 or 58 therefore remains telescopically adjustable in the stand 11 or 12.
  • the adjustment is carried out when the adjusting spindle 57 is rotated via the bevel gear 55.
  • the bevel gear 55 is fixed in a rotationally fixed manner on the bearing section 56 by means of the screw 29.
  • the cross member 10 is a U-shaped section which receives a drivable shaft 49.
  • This shaft 49 is rotatably supported in bearing plates 50 and 52, which are fixed in the interior of the cross member 10.
  • the ends of the shaft 49 protrude into the upper end of the stands 11 and 12 and carry non-rotatably bevel gears 54 which are in engagement with the bevel gears 55 of the adjusting spindles 57.
  • the open top of the cross member 10 is closed by means of a snap-on cover plate, which is removed in the top view according to FIG. 5.
  • the drivable shaft 49 carries in the area of the bearing plate 50 a further bevel gear 51 which is connected in a rotationally fixed manner to a bevel gear 53 of a drive shaft consisting of the parts 34 and 46.
  • the bearing plate 52 designed as an angle also forms a bearing for the end of the part 46 of the drive shaft which carries the bevel gear 53.
  • the part 34 of the drive shaft is axially adjustable in the hollow part 46 of the drive shaft, but is non-rotatably guided.
  • the part 46 is rotatably supported in further bearings 47 and 48 on the inside of the boom 14, as the view according to FIG. 4 shows.
  • a bracket 36 is fastened on the inside, which holds the connecting part 45 of the crank 35 non-rotatably when the part 34 is retracted.
  • the crank 45 at the end of part 34 of the drive shaft must first be set horizontally so that there is as much freedom of movement as possible under the worktop. This allows the set height of the worktop to be locked at the same time.
  • 1 and 2 show, additional guide slides are adjustable between the cross member 10 and the mounting brackets 20 and 27 on the stands 11 and 12.
  • Each guide carriage has two fastening plates 23 and 24 or 30 and 31 which run parallel to one another and which are connected to one another by means of four bearing bolts. In this case, two bearing bolts are provided along the vertical edges of the fastening plates, on which rollers 25 and 26 or 32 and 33 are rotatably mounted, which have a tread adapted to the outer contour of the stands 11 and 12.
  • the fitting according to Figs. 1 to 5 is inserted from above into a table frame, the mounting brackets 20 and 27 and a mounting plate, e.g. 23 and 30 of the guide carriage are connected to a wall of the prefabricated table frame, which can also be designed as a base cabinet. Then only the prefabricated worktop needs to be connected to the support frame and the work table is fully assembled. The assembly effort in the manufacturing of the furniture parts is therefore very low, since the fitting is a unit in itself that quickly and easily combines the table frame and worktop so that the worktop can be changed not only in its working height, but also in its inclination.
