Definitions

  • the invention relates to an arrangement for hanging a working platform in a holder fastened to a wall of a building, the working platform having a holding part which is held in a receiving space of the holder in the working position of the working platform.
  • shoes are attached to a work platform for hanging, which are slotted from below.
  • the work platform is suspended from above in holders called hanging rings, the shoes engaging behind the hanging rings.
  • a safety pin is inserted through the shoe below the hanging ring.
  • the object of the invention is to design an arrangement for hanging a working platform in such a way that the working platform is immediately and securely hung in the holder in the working position without further activities or additional securing means against unintentional unhooking.
  • This object is achieved in that the holding part is positively locked in the receiving space in the working position of the working platform, and that the locking is lifted only in a horizontal position parallel to the wall and through the receiving space pivoted upward position of the working platform.
  • the invention has the advantage that for unlocking and thus for hanging and unhooking the work platform, it is so inclined that it is not accessible, but on the other hand immediately after hanging by swiveling into a horizontal and thus accessible position without any additional part and without any Handle is secured and can be used. It can therefore only be walked on when it is secured by swiveling it down into the working position.
  • the inclined position of the work platform prevents anyone from walking on it.
  • Embodiments of the invention can be implemented in a variety of ways, e.g. B. by articulated cables or cables, which bring about the locking and are driven downwards by the pivoting of the working platform, and which, for example, have parts which, when pivoting the working platform downwards on the wall, on the holder or on another, are fixed relative to the pivoting movement Point to the plant.
  • the locking can be done in any way, for. B. by inserting a bolt made by the joint or cable into a recess located in the counterpart.
  • the receiving space of the holder extends downwards. This enables the pivoting movement of the working platform to be used directly for locking if, in one embodiment of the invention, the holding part, which is held in the receiving space of the holder in the working position of the working platform, has a cross-section deviating from the circular shape. No moving parts are required on the work platform or bracket.
  • the cross-sectional shape is selected such that the holding part is inserted from above into the downwardly widening receiving space only in the pivoted upward position of the working platform through a narrow insertion opening and is rotated and locked in the lower, enlarged region of the receiving space can be.
  • the cross-section deviating from the circular shape can have any shape, e.g. B. also be elliptical.
  • the upward pivoted position of the work platform sets itself when it is attached to a hoist at suitable locations, e.g. B. on a guardrail on the edge of the work platform facing away from the wall is attached.
  • a certain swivel position can also be achieved by specifically attaching the work platform to the hoist.
  • the locking is released only in the position of the work platform pivoted upward by approximately 45 °.
  • the swivel angle of 45 ° prevents the still unsecured work platform from being walked on.
  • a swivel angle of 45 ° is not so large that a protective railing attached to the work platform hits the wall on which the work platform is to be suspended. Therefore, a guardrail attached to the work platform does not hinder the hanging or unhooking of the work platform.
  • the work platform is attached to a crane at two points on its guardrail, approximately half to two thirds of the height of the rail, for example, so that the work platform hovers freely by itself 45 ° inclined position. In this position, the work platform can be suspended from above in the holder and swivels into its working position when it is lowered further.
  • the holding part with the cross-section deviating from the circular shape is designed as a profile tube or profile rod rigidly attached to the working platform. Its cross-sectional dimensions can be easily selected and the receiving space of the holder can be easily designed so that the lock in the working position the working platform is guaranteed and can only be lifted by swiveling the working platform upwards.
  • the profile tube is a square tube, the cross-sectional diagonal of which runs parallel to the accessible work surface of the work platform. Since a square tube is a stable component, in one embodiment of the invention it can serve as a supporting support element of the work platform with which it is supported on the wall via the holder. However, any other (e.g. L- or U-shaped), also plate-shaped profiles can be used.
  • the holder of an embodiment of the invention has a base plate intended for attachment to the wall and at least one hook approximately perpendicular to the base plate, which, viewed from the side, can have the shape of a curved finger pointing upwards in order to form the receiving space.
  • the space between this hook and the base plate of the holder decreases upwards, it forms the receiving space of the holder.
  • This holder can be U-shaped, T-shaped or L-shaped in plan view.
  • the yoke of the U, the transverse side of the T or one leg of the L form the base plate, the two legs of the U, the leg of the T or the other leg of the L form the hook standing at right angles to the base plate. This design makes it very easy to produce a stable holder.
  • An embodiment of the arrangement according to the invention is designed so that the space between the base plate and the upper end of the hook of the holder is smaller than the width of the projection surface of the profile tube parallel to the accessible work surface of the work platform and equal to or larger than that smallest possible projection surface of the profile tube is parallel to its longitudinal axis.
  • the work platform has a deflector which, when the work platform is lowered in a horizontal position, pushes the holding part away from the insertion opening of the receiving space in the holder by sliding on an inclined surface of the holder. This prevents the holding part of the working platform from being unlocked and placed loosely from above onto the holder without the holding part entering the receiving space for locking.
  • this inclined surface is formed by an outer surface of the holder.
  • the deflector has a plate which is at an angle from the underside of the work platform to the wall. This embodiment of the deflector and the holder cause the work platform to slide over the inclined surface of the holder if it is not properly suspended in the holder.
  • Embodiments of the deflector are designed so that when the working platform is suspended in the receiving space, the surface of the deflector facing the holder keeps a distance from the inclined surface of the holder when the working platform is pivoted from the position pivoted upwards for hanging in, or else the deflector on this slipped.
  • the deflector and the inclined surface of the holder can work together so that the holding part in the raised position of the work platform in the Recording space can enter and when the holding part has entered the receiving space when the work platform is pivoted downwards, it is moved away from the wall by the abutment of the deflector on the inclined surface of the holder and the holding part thereby comes under an undercut in the edge of the receiving space and there by the deflector remains locked on the inclined surface until this locking is released by swiveling up the work platform.
  • the undercut is formed by an inclined surface which, after the work platform has been swung up and unlocked, facilitates the exit of the holding part from the receiving space.
  • the holding part can also have a circular cross section.
  • the locking occurs due to the pivoting movement of the working platform in its horizontal working position, either by changing the effective cross section of the holding part or by a displacement of the working platform caused by the pivoting movement away from the wall and thereby resulting in the holding part entering an undercut in the Edge of the recording room.
  • embodiments of the invention are designed so that they make use of both of the above-mentioned locking mechanisms.
  • the work platform can be suspended in the holder at any point on the holding part.
  • the distance between the two brackets required to hang up a work platform can be varied. Their distance from one another does not need to be measured precisely.
  • the work platform can be moved laterally by a certain distance. This eliminates the need to measure the holder accurately.
  • the work platform 1 shown in Fig. 1 is suspended and locked in the working position with its holding part 2 in two coolers 3.
  • the holders 3 are attached to a wall 4.
  • the work platform 1 is supported on the underside of the support struts 5 against the wall 4.
  • FIG. 2 shows the arrangement for hanging in the work platform 1 from FIG. 1 on an enlarged scale.
  • the holder 3 is fastened to the wall 4 with a screw 6 and a tie rod (not shown). It consists of a U-shaped plate in plan view.
  • the yoke of the U forms a base plate 7 for attaching the holder 3.
  • the two legs of the U each form a hook 8 which, seen from the side, has the shape of a curved finger pointing upwards.
  • the space between the base plate 7 and the hook 8 of the holder 3 decreases upwards.
  • the hooks 8 and the base plate 7 delimit a receiving space 9.
  • a square tube 10 is welded onto the work platform 1 as a holding part 2.
  • the cross-sectional diagonal 11 of the square tube 10 runs parallel to the working plane of the work platform 1.
  • the cross-sectional diagonal 11 of the square tube 10 is longer than the space between the base plate 7 and the upper free ends of the hooks 8, that is to say larger than the clear width of the insertion opening 12.
  • the square tube 10 has a square cross section with a side length 13 which is smaller than the inside width of the insertion opening 12. If the work platform 1 is therefore in the swiveled-up position shown in FIG. 2, the square tube 10 can be moved into the receiving space 9 . If the working platform 1 is subsequently pivoted into the horizontal and accessible working position shown in FIG. 3, the square tube 10 attached to the working platform 1 rotates about its longitudinal axis 14. The clear width of the receiving space 9 decreases upwards, so that the square tube 10 In the horizontal position of the working platform 1 shown in FIG. 3, it cannot emerge from the receiving space 9, since the clear width of the insertion opening 12 of the receiving space 9, as already mentioned, is smaller than the cross-sectional diagonal 11 of the square tube 10.
  • the working platform 1 If the working platform 1 be unhooked, it must first be brought into the position shown in FIG. 2, preferably pivoted upwards by an angle of 45 ° from the horizontal, so that the square tube 10 is rotated again into the position shown in FIG. 2, in which it can emerge from the receiving space 9.
  • a deflector 15 is attached to the underside of the work platform 1 and is angled obliquely downwards to the wall 4.
  • An outer edge 16 of the hook 8 of the holder 3 extends upward from the insertion opening 12 of the receiving space 9 obliquely downward from the wall 4, then merges into an arc which, for. B. may have the shape of a circular arc segment around the longitudinal axis 14 of the square tube 10, and then runs obliquely to the wall 4 downwards, parallel to the deflector 15.
  • the distance of the outer edge 16 at the top of the insertion opening 12 from the Wall 4 is so small that the deflector 15 abuts and slides against the outer edge 16 when the working platform 1 is lowered from above onto the holder 3 in a horizontal position, as shown in FIG. 4.
  • a receiving space 17 has an undercut 18.
  • Inclined surfaces 19 of the hooks 8 and the shape of a deflector 20 are selected such that the deflector 20, even when the holding part 21 has entered the receiving space 17, pushes it slightly away from the wall 4 when the working platform 1 is pivoted downward, and the holding part 21 in the undercut 18 locked. If the deflector 20 causes the work platform 1 to move away from the wall 4 when the work platform 1 is pivoted away, so that the holding part 21 enters an undercut 18, the holding part 21 can also have a circular cross section.
  • the distance between two holders 3 from one another can be chosen almost arbitrarily, since the area of the square tube 10 welded to the working platform 1, with which the working platform 1 can be suspended in the holder 3, extends a little inwards from the outside of the working platform 1.
  • the working platform 1 is thereby brought into a position pivoted upward by approximately 45 ° from the horizontal by placing it on a protective railing 22 (see FIG. 1), which is located on its side facing away from the holding part 2, on a crane is appended.
  • a protective railing 22 see FIG. 1
  • the working platform 1 is transported to the holders 3 by means of the crane, the holding part coming to bear against the wall 4.
  • the holding part 2 passes through the narrow insertion opening 12 into the receiving space 9.
  • the holding part 2 is inserted in the receiving space 9 (as shown in FIG.
  • the working platform 1 swivels when the crane hook is lowered further the longitudinal axis 14 of the holding part 2 in its horizontal working position (FIG. 3), in which it is supported on the wall 4 with support struts 5 on its underside (FIG. 1).
  • the work platform 1 can then be used immediately. Since the clear distance between the base plate 7 and the hooks 8 in the upper region of the receiving space 9 is smaller than the diagonal 11 of the square tube 10 welded to the work platform 1, the work platform 1 cannot be removed from the holders 3 without first having to To be swiveled 45 ° and then raised. An unintentional unhooking of the work platform 1 from the holders 3 is reliably prevented.
  • One or more deflectors 15 on the underside of the work platform 1 extend laterally along the area in which the square tube 10 can be hung in the holder 3.
  • the deflectors 15 ensure that the work platform 1 with the square tube 10 is suspended in the holder 3 and can not only be placed on it from above.
  • a flat iron is welded to the square tube 10 (not shown), which prevents the work platform 1 from being suspended in the holder 3 in this area. This will prevent the Working platform 1 protrudes laterally too far over the holder 3 and that the holders 3 are arranged too close to one another. As a result, a tilting moment of the work platform 1 is limited, which occurs when the work platform 1 is loaded laterally outside the two holders 3 into which it is suspended. The other holder 3 receives a tilting moment around the holder 3 closer to the load.
