Definitions

  • the invention is based on a height-adjustable footrest, in particular for assembly tables, according to the preamble of claim 1.
  • a footrest is known from DE 41 29 496 Cl, which is held on a frame with a prestressed tension spring and at least on one side in a vertical guide of the Is guided.
  • the vertical guide is designed with a toothed rack which is engaged by a toothed wheel mounted on the footrest.
  • a pawl is provided, which, spaced from the gearwheel, engages in the rack arranged on the vertical guide and locks the footrest.
  • the height-adjustable footrest according to the invention with the characterizing features of claim 1 has the advantage that it is of simpler construction, with the pawl engaging in the rack being dispensed with. This eliminates the wear on the rack caused by the engagement of the pawl. Due to the action of the prestressed spring, the counter bearing is pressed against the first guide surface and the clamping jaws against the second guide surface of the guide, so that a
  • Tilting of the guide is generated, whereby the inclined footrest is locked in the desired position.
  • the footrest is infinitely adjustable.
  • the measures listed in the subclaims enable advantageous developments of the height-adjustable footrest specified in claim 1. Good guidance of the footrest when adjusting the height is achieved if the counter bearing is pivoted and has a bearing surface for the guide surface. A jamming when guiding on two vertical guides is excluded in that the gears on the two guides are connected to one another in a rotationally fixed manner by means of a shaft.
  • FIG. 1 shows a sectional view through an assembly table with a height-adjustable footrest according to the invention
  • FIG. 2 shows a section through a vertical guide for the height-adjustable footrest according to line II-II according to FIG. 1
  • FIG. 3 shows a sectional view along line III-III according to FIG. 2 .
  • 10 denotes an assembly table, which is designed with a frame 11 made of profile elements 12, which are partially indicated in cross section, and with a worktop 13. A more precise design of the assembly table 10 is dispensed with at this point, since such a structure is generally known.
  • a vertical guide rod 15 is fastened to the two narrow sides of the assembly table 10 with a rear guide surface 16 and a front guide surface 17 viewed by the worker on the assembly table.
  • the guide rods 15 are, for example also made of profiled elements which are fastened to the frame 11 of the assembly table 10
  • the guide rods 15 are only fastened to the frame 11 at the bottom.
  • the profile elements of the guide rods 15 have, for example, at least on the rear guide surface 16, a T-groove 19 cut in the hip.
  • the toothed rack 18 is composed of toothed rack segments 18 ′ which are inserted into the T-slot 19 provided on the rear guide surface 16. The attachment and the lined up arrangement of the
  • the two guide rods 15 serve to guide a height-adjustable footrest 20. However, it is also conceivable to provide only one guide rod 15 on which the height-adjustable footrest 20 is guided.
  • the footrest 20 is expediently formed from a frame 21 made of profiled elements, which is covered with a plate 22.
  • FIGS. 2 and 3 The guidance of the footrest 20 on the guide rods 15 can be seen more clearly from FIGS. 2 and 3, only one of the two guide rods 15 being shown.
  • a respective bearing plate 24 On opposite side profiles of the frame 21 of the footrest 20, a respective bearing plate 24 is fastened.
  • a prestressed tension spring 35 At the rear of the footrest 20 there is a prestressed tension spring 35 on both sides, each with a fixed spring suspension 36 on the guide rod 15 or on the frame 11 and with a movable spring suspension 37 on the height-adjustable footrest 20, for example on the bearing plate 24. is attached.
  • the shaft 26 is supported on both sides in a bearing 32 arranged on the clamping jaws 27. However, it is also possible to mount the bearings 32 in the bearing plate 24.
  • the shaft 26 protrudes beyond the frame 21 of the footrests 20 on both sides, a gear wheel 31 being attached to the protruding ends of the shaft 26 in a rotational test.
  • the counter bearing 29 is pivotally mounted on the journal 28.
  • the counter bearing 29 has a bearing surface 30 which acts on the front guide surface 17.
  • the pivot axis of the counter bearing 29 and the axis of rotation of the gear 31 are in the horizontal position of the
  • Footrest 20 in a horizontal plane.
  • the clear width between the gear 31 and the support surface 30 of the counter bearing 29 is dimensioned such that in the horizontal position of the footrest 20 between the front guide surface 17 and the support surface 30 there is play and the gear 31 can roll along the rack 18.
  • the clamping jaws 27 are block-shaped and consist, for example, of a steel plate which is welded to the bearing plate 24.
  • the clamping jaws 27 have an edge 33 which, in the direction of the tilting moment caused by the tension spring 35, acts on the rear guide surface 16 outside the toothed rack 18 at a distance from the bearing surface 30 of the counter bearing 29. Since the jaws 27 are made of steel and the profile of the guide rod 15 There is aluminum, the guide surface 16 is expediently covered with a steel sheet in the region of the attack of the edge 33.
  • the frame 11 does not necessarily have to be a table 10, but can also be a frame or stand which serves to fasten the guide rods 15.
  • the footrest 20 can thus also be used as a free-standing footrest.

Abstract

Ce repose-pied (20) réglable en hauteur, notamment pour une table de montage (10), est guidé sur au moins une barre de guidage verticale (15) avec une première surface de guidage (16) et une seconde surface de guidage (17). La première surface de guidage (16) comprend une crémaillère (18) sur laquelle roule une roue dentée (31) montée rotative sur le repose-pied (20). Un ressort de traction (35) précontraint vient en contact avec le repose-pied (20). Sur sa surface de guidage (17) opposée à la crémaillère (18), le repose-pied (20) comprend une butée pivotante (29). Dans une position inclinée du repose-pied (20), une mâchoire de serrage (27) sollicitée par le ressort de traction (35) vient en contact avec la surface de guidage (16) opposée à la surface de guidage (17) pour la butée (29), de façon à bloquer le repose-pied (20) dans la position inclinée sur la barre de guidage (15).
