Definitions

  • the invention relates to a device for fastening Scaffolding elements according to the preamble of claim 1.
  • the attachment of the treads snap claws known become, for example, a crossbar one Have scaffolding hook-shaped claw housing, in which a locking bracket is rotatably mounted.
  • Such Snap claw is for example in EP 348 885.
  • the snap claw is replaced by a Return spring in the closed, locked position pressed.
  • the return spring is designed so strong that the tread can be placed on a crossbar of the scaffold without that the snap claw by the weight of the tread automatically engages.
  • Such a system which can also be dismantled by individual persons Snap claw regardless of the weight of the tread and thus of the size or the material has been used continued to develop a snap claw and put it into retail brought in by the geometry of the locking bracket in Connection with the arrangement of the axis of rotation of the locking bracket when Placing on a crossbar regardless of the Return spring pressed into its closed position and so automatic locking is avoided.
  • Such a snap claw is the most diverse Treads can be used.
  • the axis of rotation also remains when the support is in place of the tread on a level surface in its closed Position, which increases the total height of the level For example, on the floor or on a surface Loading area lying tread enlarged.
  • the object of the present invention is therefore a To create snap claw that is independent of the spring force placing on a scaffold part, for example one Cross bolt without automatic snap-in enables, with the storage on a flat surface a reduction in Total height should be achieved.
  • This task is based on a snap claw after the Preamble of claim 1 by its characterizing Features resolved.
  • one according to the invention is distinguished Snap claw in that a further edition on Locking bracket is provided, their arrangement in relation to Axis of rotation is designed so that when placed on a flat surface a torque towards the open Position is effected. This torque turns the Locking bracket, so that the total height of the device at Storage on a level surface reduced.
  • the desired torques can be at for example in a clockwise rotation locking bracket generate in that the closing edition in the closed position of the locking bracket itself immediately vertically below the axis of rotation or to the left of the Is vertical while the opening pad to the right of the vertical passing through the axis of rotation located. With a closing in the left turn The claws are reversed accordingly To provide arrangement.
  • Locking bracket is a projection pointing away from the axis of rotation provided, which includes the opening pad. Through the Rest of the locking bracket on this projection will this Place it on a level surface, for example on the floor or on a loading area of a transport vehicle so far rotated until the remaining area of the locking bracket, the then comes into contact with the surface the side of the perpendicular through the axis of rotation on which the opening movement is effected.
  • actuating element for manual actuation the locking bracket provided. This makes opening the Locking claw by the operator before lifting and Place on the scaffolding element.
  • At least one stop for limiting the opening rotation of the locking bracket intended can, for example be caused that the above-mentioned projection on a Basic body of the snap claw during swiveling strikes.
  • the locking bracket on its top with a stop Mistake can for example, as a claw housing open at the bottom become.
  • the bottom of the claw housing immediately as a counter strike for the one at the top of the Stopper provided stop serve.
  • This stop can for example, be formed so that it Withstands permanent loads without damage.
  • a stop for the limitation is also preferred the closing movement of the locking bracket provided.
  • This Stop can be formed, for example, by a rivet be on the inside of the locking bracket from the Claw housing protrudes or penetrates this. This Ultimately, the stop bears the weight of the corresponding one Scaffolding element, e.g. B. a tread with loose support on a crossbar or other scaffolding part.
  • the Rest of the locking bracket which when you put the locking claw on a scaffold part such as a crossbar is used as flat surface.
  • the scaffolding parts on which this Circulation is usually with a round Provide cross section. Now the overlay becomes a flat surface trained, so this flat contact surface on the round Scaffold part when tilted, e.g. B. by lifting the opposite end of the scaffold element without essential Roll off the change of position of the support point slightly.
  • a Coil spring on the axis of rotation of the locking bracket for generation the restoring force used This represents an expedient and space-saving way to generate the Restoring force, which also with little effort is accomplished.
  • a claw housing 2 which is hook-shaped and accordingly one Receptacle 3 for a crossbar 4 of a scaffold, for example, a mobile scaffold.
  • a profile 6 for more stable and lighter connection with a scaffold part for example, with a tread.
  • a locking bracket 7, for gripping the cross bar 4th is angular, is rotatable about an axis of rotation 8 stored in the claw housing 2.
  • One on the axis of rotation 8 attached coil spring 9 is supported at one end 10 a designated nose 11 of the claw housing 2 and the other end 12 on the locking bracket 7.
  • the coil spring 9 presses the locking bracket 7 thus in its shown in Fig. 1 closed rest position.
  • the locking bracket 7 the crossbar 4 so that the scaffold covering attached to it is secured against unintentional lifting.
  • the arrow A is the vertical above the support point 14 the support level 13 shown on the crossbar 4.
  • the Arrow D marks the perpendicular that falls from the axis of rotation 8 becomes.
  • the bearing point 14 is clearly visible to the left of the perpendicular through the axis of rotation 8.
  • a torque S which Locking bracket 7 presses in a right turn, but by the stop 15 is blocked.
  • the helical spring 9 thus loosely rests the latching claw 1 the crossbar 4 on, without an automatic snap of the locking bracket 7 on the crossbar 4 is possible.
  • the Einrastk, laue 1 has a maximum height H.
  • the snap claw 1 is on a level Underground 16 shown depicted.
  • the locking bracket 7 is pressed into its uppermost position, in the one Projection 17 on a lower edge 18 of the claw housing 2 triggers.
  • the upper stop surface 19 lies on the underside 20 of the claw housing 2, so that on this Place the substantial portion of that at the Snap claw 1 attached scaffold part to the locking bracket 7 acting weight is carried.
  • the projection 17 has a support tip 21 and one Actuating surface 22.
  • the actuating surface 22 is for manual actuation of the locking bracket 17, for example Release from the locked position shown in FIG. 1 is an advantage.
  • the security function is against unintentional loosening, for example against lifting off guaranteed a tread (see Fig. 1). Furthermore can by pressing on the locking bracket 7 on the actuating surface 22 a tread with latching claw 1 released from the crossbar 4 and be raised. After releasing the operating surface 22 is the locking bracket 7 by the coil spring 8 in its closed position according to FIG. 2 pressed. In this Position of the locking bracket 7, the locking claw 1 together with the attached tread or other scaffolding the crossbar 4 are stored loosely. Due to the location of the Contact point 14 next to the Lot D below the axis of rotation 8 results a torque S that the locking bracket 7 regardless of the Spring 9 holds in the closed position shown. A weight force acting from above can therefore not cause the locking claw 1 to engage automatically.
  • the locking claw 1 has a maximum height H.
  • this part can be placed on a flat surface 16, for example on the floor.
  • the latching bracket 7 initially rests with its support tip 21 'on the flat surface 16', whereby a torque M is generated which rotates the latching bracket 7 'against the restoring force of the coil spring 9.
  • the support area 20 ', with which the latching bracket 7 comes into contact with the flat surface 16, 16' in the course of laying down, is brought to the right side with respect to the vertical D through the axis of rotation 8 during the rotational movement of the latching bracket 7, 7 ' .
  • the opening rotational movement of the latching bracket 7 also continues when the support region 20 'rests on the flat base 16, as a result of which the stop tip 21 is then lifted off the flat base 16 again.
  • the locking bracket 7 is rotated by the weight of the tread, which acts on the locking claw 1, until it strikes with its stop surface 19 on the underside of the claw housing 2.
  • the height h of the snap claw becomes minimal.
  • the difference between the maximum height H and the minimum height h is particularly important when stacking treads with snap-in claws according to the invention, since less height is required as a result.
  • the procedure described can be reversed Order.
  • the procedure described can be reversed Order.
  • the locking bracket 7 When lifting the Snap claw 1 from a flat surface, for example from the floor or a loading area of a transport vehicle pivots the locking bracket 7 through the coil spring 9 the intermediate position 7 'according to the closed position Fig. 2.
  • the tread can first loosely on the Crossbar 4 and another, not shown Crossbar on the opposite side of the tread be put on. This process is as easy as the described disassembly of the tread by a single Person.
