Definitions

  • the invention relates to a table with a table frame, a table top and two support devices which are articulated with the one ends on the table frame and with the other ends on the underside of the table top and are pivotable by means of an actuating device, the table top by means of the actuating device both in the Height as well as the inclination is adjustable.
  • a table of this type is known from DE-A-32 24 540.
  • the height can be adjusted without changing the inclination of the table top.
  • the actuating device required for this requires a complicated mechanism with many parts, all of which are arranged below the table top and are coupled to the table top and the table frame.
  • several lever chains are provided in the actuating device, which allow an unambiguous adjustment in a limited area, when a secure determination of the set height and inclination of the table top is desired.
  • an adjusting device for a table is known, with which the height or the height and the inclination of the table top can be changed.
  • the front edge of the table top must be actuated in order to actuate a coupling in the actuating device.
  • the height of the front edge of the table top remains at approximately the same height.
  • This change in the inclination of the table top causes a simultaneous height adjustment of the table top and the operation of the actuating device is not easy, since in addition to the actuation of the actuating device via the table top, the clutch must be kept actuated.
  • DE-A-30 39 180 shows a table in which the height and inclination of the table top can also be changed independently of one another.
  • two actuating devices are provided for this purpose, which can be actuated separately, the actuating points being locally separated from one another.
  • the support devices in the upper region of the transverse center of the table frame are articulated about transverse pivot axes on the table frame, that the support devices on the underside of the tabletop are supported on transverse pivot axes on the table top, but in the depth of the table top are adjustable so that the adjusting device pivots the support devices either individually or together towards the table top or lowers towards the table frame, the table-side pivot axes of the support devices moving towards or away from each other, and that when pivoting a support device only the inclination of the table top and only the height of the table top can be changed when the two supporting devices are pivoted together while maintaining the inclination.
  • the adjustment mechanism only requires the two support devices which are fixed to the table frame, but can be swiveled and swiveled on the table top and are adjustable perpendicular to the swivel axis. With the adjusting device, the support devices can be pivoted individually or together, and it is then automatically determined whether only the inclination of the table top or only the height of the table top is changed while maintaining the inclination.
  • each support device is designed as a pair of pivot levers spaced apart in the transverse direction.
  • each support device is designed as a plate-shaped support cheek extending over the essential part of the transverse direction.
  • each support device is supported on the table top via two joints forming the pivot axis, that the joints are arranged on sliders that are guided in pairs and in opposite directions in guide rails, and that the guide rails extend towards the depth of the table top.
  • the guide rails are designed as C-profile sections, and that the sliders carry tabs which protrude from the guide rails and are designed for articulating the support devices. The sliders are clearly guided and offer an easy way to link the support devices without limiting their swivel range.
  • the articulation of the support devices on the table frame is solved according to one embodiment so that the table frame has two lateral supports resting on feet, which are connected to one another in the region of the upper transverse center by means of a frame, and that the support devices in the region of the front and rear side of the frame are articulated.
  • a further embodiment provides that at least one guide arm is articulated on the underside of the table top between the support devices, which is articulated in the area of the rear side of the table Frame supported on the table frame.
  • a spur gear is rotatably mounted between the two sliders, the axis of rotation running in the transverse direction of the table top, that the spur gear is diametrically engaged with two racks which run along the guide rail and are firmly connected to the adjustable glides in this guide rail.
  • the pivoting movements can be transmitted to the support devices in such a way that two threaded spindles running in the longitudinal direction of the guide rails are used as the adjusting device, which are adjustable in threaded bores of the sliders, but are non-displaceable and freely rotatable on the underside of the table top.
  • the threaded spindles assigned to the adjusting devices can be driven individually or together depending on whether the inclination or the height of the table top is to be changed.
  • a common threaded spindle with two opposite threaded sections is used as the adjusting device for the two sliders adjustable in a guide rail is, which is adjustable in corresponding counter-threaded bores of the slider, but is immovable and freely rotatable on the underside of the table top.
  • the option of changing the height or the inclination is additionally provided that the two threaded sections of the threaded spindle are connected to one another by means of a coupling, that only a drive section is assigned to the threaded section directed towards the front of the table top, and that when the coupling is engaged, the height and at disengaged clutch the inclination of the table top can be changed by means of the single drive.
  • each support device is guided into the two supports of the table frame by means of an extension, that each extension is coupled to a driver which is adjustable on a horizontal threaded shaft rotatably mounted in the support, that each Threaded shaft rotatably supports a drive pulley that the drive pulleys assigned to a support device can be set in rotation by means of an endless ball chain that can be operated in both directions, and that at least one, preferably the endless ball chain assigned to the front support device can be driven individually and both endless ball chains can be driven together are.
  • the common drive of the two endless ball chains for changing the height of the table top is facilitated by the fact that the threaded shafts assigned to the two support devices have opposite sense of thread and that the two endless ball chains rotate in the same direction when the drive is common, since both drive coupling disks only with the Drive must be coupled, which is achieved in a particularly simple manner in that the endless ball chains over each an arranged on the underside of the table top drive coupling plate are guided, that the two drive coupling plates are arranged one behind the other with a common axis of rotation, and that as a drive a hand crank or a drive motor can be optionally coupled to one or both drive receptacles of the drive coupling plates. It is sufficient to fix the hoses or pipes in the base frame in order to obtain a defined circulation of the endless ball chains between the drive coupling plates and the drive plates on the threaded shafts.
  • Fig. 1 shows a table according to the invention from top to bottom, the table top 2, including the frame 4, which is made of hollow profiles made of light metal.
  • Base 6 with feet 8 can be seen, the front parts of which are longer than the rear parts.
  • the feet 8 carry two supports 10 and the frame 12 which is fastened between the two supports 10 and connects them to one another.
  • the frame 12 is designed as a hollow box profile and has the shape of a U open in cross-section.
  • Two support devices 14 and 15 designed as support plates are pivotably attached to the frame 12.
  • the table has the front support device 14 and the rear support device 15.
  • the support devices 14 and 15 are formed as hollow profiles made of sheet metal, which can be reinforced by transverse beads.
  • Both actuators 14 and 15 are pivotally mounted on the frame 12 about the axes 16 and 17 which run in their longitudinal direction, ie in the transverse direction of the table top.
  • the arm 18 is pivotally mounted, likewise about the axis 17 running in the longitudinal direction thereof.
  • 3 to 5 show how the table top 2 can be adjusted. If the two support devices 14 and 15 are swiveled upwards together, the table top 2 is raised, both adjusting devices 14 and 15 are swiveled downwards together, then the table top 2 is also lowered. If the rear adjusting device 15 remains at the top while the front adjusting device 14 is being lowered, the table top 2 assumes a forward inclination which is determined by the pivoting angle of the front supporting device 14.
  • FIG. 7 which can be put together to form a single figure, provide details for the adjustment of the support devices 14 and 15.
  • the support devices 14 and 15 have their edges facing away from the frame 12 and are close their outer right and left ends, two tabs 20, which are rigidly attached to the supports 14 and 15.
  • the outer ends of the tabs 20 are each mounted in a slider 22 or 23 with an internal thread about axes 24.
  • the front (22) and the rear sliders 23 are slidably guided in downwardly open C-profiles as guide rails 26 of the frame 4.
  • Two sections 28 and 29 of a threaded spindle 27 are rotatably and non-displaceably mounted in the guide rails 26 designed as a C-profile.
  • Sections 28 and 29 have opposite threads, e.g. the front section 18 is a right-hand thread, the rear section 29 is a left-hand thread.
  • Corresponding internal threads have the associated front and rear sliders 22 and 23, respectively. Between the two sections 28 and 29 of the threaded spindles there is a coupling 32.
  • the clutch 32 is held engaged by a compression spring 34, it can be pulled over the tension element 36, e.g. a wire, disengage with the hand button 38 and, after releasing the hand button 38, returns to the position shown in which the two sections 28, 29 are coupled to one another.
  • the hand crank 40 which is formed from the turntable 42 and the foldable handle 44, is used to drive the front section 28 of the threaded spindle 27.
  • the crank handle 40 is in drive connection with the front section 28 of the threaded spindle 27 via the angular gear 46.
  • the rear section 29 of the threaded spindle 27 is also rotated via the clutch 32, namely in the same direction of rotation. Since both sections 28 and 29 have opposite threads, in one direction of rotation the hand crank 40, for example, the slider 22 is moved forward (to the left in FIG. 2a), the slider 23, however, is moved backwards. As a result, the supports 14 and 15 and the table top 2 lowered. In the opposite direction of rotation of the crank handle 40, the support devices 14 and 15 and the table top 2 are raised accordingly.
  • the threaded spindles 27 can also be coupled so that they are e.g. a single crank handle 40, are rotatable.
  • electric motors in particular tubular motors, can also be provided, which can be driven in opposite directions of rotation.
  • the arm 18 is located approximately in the middle of the table (viewed from left to right), which initially serves to secure the table top 2 against displacement from the front to the rear. Since the described sliders 22, 23 are freely displaceable in the guide rails 26 of the frame 4, this means that the entire frame 4 and thus the table top 2 can be freely moved from front to back, regardless of the setting of the table top 2 in height and of inclination.
  • the arm 18 is mounted on the rear of the frame 12 so as to be freely pivotable about the axis 50 running in the longitudinal direction thereof (cf. FIG. 6).
  • the upper end of the arm 18 is articulated to the slider 52.
  • the slider 52 is freely displaceably mounted in a C-profile 54.
  • the C-profile 54 forms the center of the frame 4 (Fig. 1).
  • An additional threaded spindle 56 is rotatably mounted in the C-profile 54. In contrast to the previously described threaded spindles 27, this has only one thread in one thread. It can also be powered by a hand crank or a motor. If the threaded spindle 56 is actuated, then it moves the C-profile 54 forwards or backwards relative to the slider 52 which remains in its position, so that the table top 2 is displaced in the same sense.
  • the arm 18 is articulated at both ends, as the axes 50 and 58 show. The arm 18 consequently makes all upward and downward movements of the table top 2 and ensures in its respective position that the table top 2 does not automatically move forward or backward, in particular when used in a set inclination.
  • the U-shaped frame 12 and the space above the frame 12 and between the actuators 14 and 15 and the frame 4 can be used to accommodate cables and accessories.
  • FIG. 8 shows another exemplary embodiment for an actuating device. Only the part of the actuating device as shown per support 10 is shown.
  • the support devices 14 and 15 which are pivotably mounted on the front and rear side of the frame 12, as can be seen from the pivot axes 16 and 17, are inserted into the support 10 with extensions 60 and 61. These extensions 60 and 61 are in receptacles of drivers 62 and 63, which are adjustable on the threaded shafts 64 and 65.
  • These threaded shafts 64 and 65 like the bearings 71, are rotatably mounted in an additional profile 70 which is inserted into the support 10. The bearing points of the threaded shafts 64 and 65 are therefore not visible on the outside of the support 10.
  • each threaded shaft 64 or 65 rotatably carries a drive pulley 66 or 67, over which an endless ball chain 68 or 69 is guided as a drive means.
  • the drive of the threaded shaft 64 and 65 can be different.
  • the two threaded shafts 64 and 65 are also actuated in the same direction of rotation. Then the threaded shafts 64 and 65 and the threads in the drivers 62 and 63 must run in opposite directions Have a sense of thread to maintain the opposite movements of the drivers 62 and 63. However, if the threaded shafts 64 and 65 are formed identically with the drivers 62 and 63, then the endless ball chains 68 and 69 must each run in opposite directions for a common adjustment of the two support devices 14 and 15. In each case, the possibility must be provided to individually drive at least one of the endless ball chains 68 and 69.

  • the drive, a hand crank, an output shaft of a drive motor or the like, is then optionally inserted only into the drive receptacle 77 or into both drive receptacles 77 and 78, as shown in FIG. 11.
  • the endless ball chain 68 can be driven alone or both endless ball chains 68 and 69 are driven in the same direction. Therefore, the thread direction of the thread shafts 64 and 65 should be selected in opposite directions.
  • the endless ball chains 68 and 69 are guided between the drive coupling disks 74 and 75 and the drive disks 64 and 65 in hoses or tubes 72 and 73.
  • cages 80 guide the endless ball chains 68 and 69 and ensure the drive connection.
  • Fig. 13 shows how actuators in both supports 10 of the table frame can be drawn into the endless ball chain drive.
  • the endless ball chain 68 in the hose or tube 72 leads over the drive coupling disk 74 and the drive shafts 64 and 64 'assigned drive disks 66 and 66' in the same direction of rotation, so that the threaded shafts 64 and 64 ', which are assigned to the support device 14, circulate in the same way.
  • the endless ball chain 68 in the hose or tube 73 runs over the drive coupling disk 75 and the threaded shafts 65 and 65 'associated drive disks 66 and 66' in the same direction of rotation, so that the threaded shafts 65 and 65 'which are assigned to the support device 15 in same way and also as the threaded shafts 64 and 64 'revolve.
  • both support devices 14 and 15 are therefore raised or lowered depending on the direction of rotation of the endless ball chains 68 and 69. 13 is that the threaded shafts 64 and 64 'with their drivers have an opposite thread as the threaded shafts 65 and 65' with their drivers in order to maintain the opposite movement of the drivers and support devices.
  • the position of the table top 2 can also be fixed by a spur gear 82 and two racks 83 and 84 in the direction of the depth of the table top 2, as shown in FIG. 14.
  • the spur gear 82 is rotatably mounted in the guide rail 26 between the sliders 22 and 23.
  • the axis of rotation extends in the transverse direction of the table top 2.

  • the ends of the racks 83 and 84 facing away from the spur gear 82 are fixedly connected to the sliders 22 and 23, so that they are adjusted synchronously with them. This ensures that the table top 2 does not move in the direction of the depth of the table top 2 even when the height is changed.
  • This forced fixation of the table top 2 is preferably carried out in each of two guide rails 26 in order to be able to adjust even large and heavy table tops 2 without tilting in height and inclination.
