Definitions

  • the invention relates to a clamping device for releasably attaching the body of a cleaning device such as a broom, scrubber or the like.
  • a clamping device for releasably attaching the body of a cleaning device such as a broom, scrubber or the like.
  • said clamping lever being pivotable perpendicular to the plane including the fork-shaped arms and being connected to it Bearing body which is clamped but rotatably held by the fork-shaped arms between the fork-shaped arms, forming the pivot axis for the clamping lever, and moves the arms between an open position and a spread clamping position when the pivot lever is actuated by means of a control cam.
  • the tensioning lever is arranged parallel to the plane including the fork-shaped arms and above it, and is embodied as a toggle lever, perpendicular to it the aforementioned plane extending hinge axis between the bifurcated arms is fixed.
  • the toggle lever acts on a slide which is arranged between the fork-shaped arms and which can therefore be moved in the direction of the fork arms.
  • One of the fork arms has an inward bend on which the slide is pushed when the tension lever is pivoted.
  • the ends of the fork-shaped arms previously inserted into the recesses on the body of the cleaning device are spread outward, and the handle is thus firmly clamped to the body.
  • toggle lever can be released very easily in a timely manner, for example by accidental contact, by bumps or the like, which can never be avoided especially when using such devices.
  • individual parts - toggle levers and sliders - are stamped parts made of sheet metal that deform easily with robust handling, so that proper function is no longer guaranteed.
  • thrust washers are arranged between the bearing body and the fork-shaped arms, which are seated on the inside by means of trunnions in the bearing body and have a diametrically continuous groove on the outside, to which the fork-shaped arms lie.
  • the bearing body is clamped between the fork-shaped arms and at the same time the thrust washers are held in a rotationally fixed manner, while the bearing body itself is free of rotation.
  • the bearing body indicates the pressure discs facing end faces curve-like projections, so that by pivoting the clamping lever, the bearing body rotates about an imaginary axis of rotation and thereby moves the thrust washers outwards.
  • the bent ends of the fork-shaped arms are braced in the recesses on the device body.
  • the invention has for its object to provide a tensioning device of the structure described above so that the bending and impact forces that usually occur when using the cleaning device, as well as the torsional forces occurring between the fork-shaped arms, can be absorbed by the tensioning device without malfunction and finally one simple training is created in terms of manufacturing and assembly technology.
  • the tensioning device practically consists of only one component, since the tensioning lever and bearing body can be formed in one piece.
  • the bearing body is inserted between the fork-shaped arms from the open side until the bends engage in its recesses.
  • the bends are spread by means of the control cam from a narrow starting position - the open position - into the clamping position, the bent ends of the fork-shaped arms being braced in the recesses on the device body.
  • the bends on the fork-shaped arms are V-shaped and the recesses on the bearing body are in the form of an inner cone.
  • the V-shaped bends are at least with one leg of the surface of the inner cone, so they are properly guided by this between the opening and the clamping position.
  • the inner cone has at least one recess with an axis which is offset eccentrically with respect to the geometric axis of the bearing body. Due to the offset of the axes, the inner cone also forms the control curve for the leg of the V-shaped bends that lie against it.
  • the bearing body is tubular, that is to say hollow on the inside, so that the V-shaped bends are exposed in the region of the apex and thus the rotation is not impaired by frictional forces.
  • an indentation which runs in the axial direction and serves to push the bearing body onto the bends arranged to form a shoulder. Due to the depression, the axial length of the bearing body is reduced at this point, so that the bearing body can be pushed onto the V-shaped bends without difficulty until they engage in the tube interior.
  • the shoulder formed by the depression also serves as a limit stop for the bearing body in one direction of rotation.
  • a groove or a rib for engaging the bends in the tensioned position is arranged approximately diametrically opposite the countersink of the bearing body.
  • the other end position, namely the clamping position, of the bearing body is fixed with this groove or rib.
  • the eccentrically offset inner cone forms a control curve for one leg of the V-shaped bends.
  • the end faces can rise from the depression to the groove or rib in a steady curve to the greatest axial length of the bearing body, whereby it can further be provided that the inner cone is only about one Half shell of the bearing body is arranged.
  • one leg of the V-shaped bends is guided over a greater length on the ion cone, the other leg, on the other hand, is carried out on a small area on the end face on the other half-shell of the bearing body.
  • the stem 1 shown in Fig. 1 consists of a tube 2, which is provided at one end with an end cap 3, which optionally also serves for hanging. At the other end, a fork is pressed into the tube 2, the ends 4, 5 of which extend in the direction of the stem and at the ends of which the body 6 of a cleaning device, e.g. a broom, scrubber or the like. is fixed by means of a clamping device 7.
  • a cleaning device e.g. a broom, scrubber or the like.
  • the forked arms 4, 5 are bent outwards at their free ends 8, 9.
  • the body 6 of the cleaning device has elongated recesses 10, 11 into which the bent ends 8, 9 of the fork-shaped arms 4, 5 can be inserted until they engage behind the underside of the body 6 or undercuts arranged in the depth of the recesses 10, 11 .
  • the clamping device 7 consists of a clamping lever 12 and a tubular bearing body 13. These two parts are integrally formed, for. B. injected as a plastic part.
  • the fork-shaped arms 4, 5 are provided with V-shaped, inwardly directed bends 16, 17 which engage in the bearing body 13 from the end faces 14, 15.
  • the apexes of the bends 16, 17 lie in the free tube space.
  • a significant depression is provided, through which a shoulder 18 (FIGS. 2, 3) is formed.
  • This depression reduces the axial extent of the bearing body sufficiently to be able to insert the bearing body from the open side between the fork-shaped arms 4, 5 until the V-shaped bends 16, 17 snap into the tube space of the bearing body 13 under slight spring force, so that the tensioning device can no longer fall down in this position (FIG. 2). Then the bent ends 8, 9 of the fork-shaped arms 4, 5 are inserted into the recesses 10, 11 on the device body 6.
  • the wall of the tubular bearing body 13 is not the same over the entire circumference, rather it is stronger in the area 21 directly behind the shoulder 18 than in the approximately diametrically opposite area 22.
  • This decrease in Wall thickness in the region of the end faces 14, 15 is achieved in that the bearing body 13 is provided on these end faces with an inner cone 20, the geometric axis of which is offset eccentrically with respect to the geometric axis of the bearing body 13.
  • This inner cone 20 forms on the one hand the contact surface for the legs 23, 24 of the V-shaped bends 16, 17 and on the other hand - due to the offset of the axes - a control curve at the same time. If the tensioning lever 12 is pivoted upwards from the position shown in FIG.
  • a type of control curve is also formed here becomes.
  • a groove 27 (FIG. 4) is arranged in the region 26, into which the upper one Snap the legs of the V-shaped bends 16, 17 into the clamping position. The tensioning lever is thus fixed in the tensioning position.
  • a rib 28 can also be provided, behind which the forked arms 4, 5 snap.
