Definitions

  • the object of the invention is now to provide a folding frame which is characterized by particularly simple handling and, moreover, has an inexpensive construction.
  • the upper ends of the legs are connected to the underside via links which, when viewed in the direction of the scissor axis, form open angles with the associated legs with respect to one another and when the legs are folded in or out to the scissor axis parallel axes of the joints connecting these links to the legs and the underside pivot, and that the links can be locked in at least one position that projects downward from the bottom and is assigned to a position of use of the legs.
  • the folding frame according to the invention can be operated in a very simple and clear manner.
  • the device to be supported for example a worktop
  • the device to be supported only needs to be lowered towards the ground after unlocking the locking of the handlebars; this automatically places the legs on the underside of the device to be supported.
  • the folding frame 3 has scissor-like, X-shaped crossed legs 4 and 5, which are each arranged in pairs, such that - cf. also Fig. 5 - one leg 4 is arranged on one long side of the tool box 2 and one leg 4 on the other long side of the tool box 2. The same applies to the legs 5. Otherwise, the legs 4 on the one hand and the legs 5 on the other hand are connected to one another in a frame-like manner.
  • each handlebar 7 are pivotally connected via joints 8.
  • These links 7 are each hinged at their other ends to bearing parts 9 on the underside of the tool box 2, in such a way that that the handlebar 7 with the associated legs 4 and 5 when viewed in the direction of the axis of the scissor joint 6 form angle ⁇ open to each other.
  • the links 7 can thus pivot relative to the legs 4 and 5 and relative to the tool box 2 about joint axes or bearing axes parallel to the axis of the scissors joint 6.
  • levers 11 are pivotally mounted, which project with their free ends between two links 7 and are acted upon by springs, not shown, such that the levers 11 each according to FIG. 5 from above on the joint axes 12 of the joints 8 between the legs 4 or 5 and the handlebars 7.
  • levers 11 are connected to one another in a U-shaped or frame-like manner.
  • an arm 13 is attached to each pair of levers 11, the free end of which can be reached by a human hand encompassing the adjacent handle 1.
  • recesses 14 are arranged transversely to the longitudinal axis of the levers 11, which are open towards the aforementioned longitudinal edges and are dimensioned such that they are able to accommodate the hinge axes 12.
  • the folding frame shown works as follows:
  • the joint axes 12 of the joints 8 are each in accordance with Fig. 5 indented in recesses 14 of the lever 11 so that the legs 4 and 5 are locked in the position of use.
  • the hinge axis 12 of the legs 4 can be accommodated on the associated levers 11 in different recesses 14 than the hinge axis 12 on the legs 5, provided that a plurality of recesses 14 are arranged on each of the levers 11. This makes it possible to set up the tool box 2 inclined relative to the ground, ie one end of the tool box 2 has a larger floor clearance than the other end.
  • the tool box 2 When the folding frame 3 is to be brought into its transport or non-use position, the tool box 2 is gripped by its handles 1 and raised slightly; at the same time, the arms 13 are pushed away with their thumbs or fingers in the direction of arrow P from the position shown in FIG. 1, so that the levers 11 also pivot and the joint axes 12 of the joints 8 are released from the recesses 14 on the levers 11.
  • the tool box 2 can now be lowered, the legs 4 and 5 successively passing through the positions shown in FIGS. 2 and 3.
  • the arms 13 of the levers 11 can be released.
  • the lower ends of the levers 11 slide over the facing longitudinal edges of the legs 4 and 5 or over sliding surfaces (not shown) arranged on the legs 4 and 5, so that the levers 11 automatically against the underside of the tool box 2 be pivoted.
  • the axis of the scissor joint 6 engages in a spring clip 15 arranged on the underside of the tool box 2.
  • toggle lever arrangements can also be provided, which are arranged between the bearing parts 10 and the joints 8 or their articulated axes 12, ie the joints 8 or their articulated axes 12 are connected by means of the toggle lever arrangements the bearing parts 10 connected.
  • the above-mentioned toggle lever arrangements are designed such that they assume an over-center position in their extended position, ie when they connect the joints 8 or their joint axes 12 and the bearing parts 10 in a substantially straight line in the view shown in FIG. 1, which are stable against thrust forces is. So that the position of use of the folding frame 3 is also securely secured.
  • rollers can be arranged on the feet of the legs in order to be able to move the tool box 2 easily, possibly in the manner of a wheelbarrow.
  • the links 7 have a pivoting range limited by stops 16 in the downward direction, ie the links 7 can only be pivoted in the downward direction up to a predetermined end position.
  • the handlebars 7 are approximately vertical in this end position relative to the underside of the tool box 2 - or also to the underside of a platform or the like supported by the folding frame 3, which can also be designed in the manner of a frame .
  • levers 17 are used, the right ends of which in FIGS. 6 and 7 on the joints 8 between the legs 4 and the associated links 7 - or also near these joints 8 on the upper ends of the legs 4 and the lower ends of the associated link 7 - are articulated and at their left ends in FIGS. 6 and 7 hook-like projections or downwardly open recesses 18 are arranged, which in the example shown cooperate with the joint axis of the joints 8 between the legs 5 and the associated links 7 .
  • the levers 17 are expediently like the legs 4 and 8 or the like on both longitudinal sides of the folding frame 3 or the box 2. arranged and close to their left in Figs. 6 and 7 ends firmly connected by a crossbar, such that the levers 17 can only be pivoted together.
  • At least one of the levers 17 is of sufficient length such that it can be easily gripped for unlocking and raised in the direction of the arrow E.
  • levers 17 can be inadvertently raised briefly, they can subsequently lock the collapsing folding frame 3 again in the half-high position of use when it falls down.
  • springs not shown, which push the levers 17 downward in addition to gravity.
  • sliding surfaces 19 are expediently arranged, on which the left ends of the levers 17 in FIGS. 6 and 7 rest when the folding frame 3 is completely folded. In this way, even with relatively short levers 17, it can be reliably prevented that the left lever ends can pivot under the plane of the legs 5 when the frame 3 is folded.
  • the lower ends of the right-hand arm 7 in FIGS. 6 and 7 pivot to the right, the levers 17 also being shifted accordingly to the right.
