This ensures that the pawl 2 in the operative position, that is, when it is received in the longitudinal slot 10 and fixed to the base body 1, about the rotation axis 6 can be rotated.
  • the clear height A of the longitudinal slot 10 in the front region is smaller than the height B of the rear part of the pawl 2.
  • the carriage 9 is explained in more detail. Under initial state, the state of the carriage 9 is understood before insertion into the guide rail.
  • the carriage 9 further includes a biasing mechanism 3, a sliding body 4 and the previously mentioned hinge pin fifth
  • the assembly of the carriage 9 is approximately as follows vonstatten: First, the rear portion 22 of the pawl 2 is introduced with the cam-like projection 26 ahead in the slot 10 of the body 1 and then rotated so far until the bore 25 in the rear part of the pawl 2 with the transverse bore 15 in the main body 1 is aligned. Thereafter, a hinge pin 5 is inserted from the side into the transverse bore 15 of the base body 1 and the bore 25 in the rear part of the pawl 2, so that the pawl 2 is fixed by means of the hinge pin 5 on the base body 1. Subsequently, the biasing mechanism 3 is fixed to the base body 1 by means of two screws 33, 34. Thereafter, the slider 4 is pushed from below onto the base body 1. Finally, the back of the slider 4 is connected via a screw 35 with the back of the body 1. Whenever spoken from above and below, or from the top or bottom, this refers to the mounting position of the carriage.

  • the biasing mechanism 3 has a plunger 31, which is loaded by a spring 32 in the direction of the pawl 1.
  • the plunger 31 abuts against the pawl 2 in the region of the constriction 23 and pushes the front part 21 downwards so far that the pawl 2 rests with its underside on the damping element 42.
  • the sliding body 4 surrounds the main body 1 with the exception of the top at least partially on all sides.
  • the slider 4 serves to reduce the friction between the guide rail and the carriage 9 when the latter is received in the guide rail.
  • the slider 4 prevents the guide rail from being significantly worn by the carriage 9.
  • Such a slider 4 is generally a wear part, which should be replaced periodically.
  • said lever ratio is greater than 2, in particular greater than 3.
  • the Fig. 4 shows the carriage according to Fig. 3b after insertion into a guide rail 7, wherein the guide rail 7 and the bottom 8 are drawn only hinted.
  • the front side of the carriage 9 or of the main body 1 is in each case the side facing away from the guide rail 7, whereas the rear side is the side of the carriage 9 or main body 1 facing the guide rail 7.
  • the arranged on the back 22 a of the pawl 2 friction surface 28 is pressed by the biasing mechanism 3 against the bottom 8 of the guide rail 7, so that the carriage 9 in the Rail 7 is locked (locked).
  • the axis of rotation 6 of the pawl 2 is selected with respect to the arranged on the rear part 22 friction surface 28 so that the friction surface 28 is moved radially towards the bottom 8 of the guide rail 7 when the front part 21 of the pawl 2 is pressed down or pulled. Conversely, friction surface 28 moves away from the bottom 8 of the guide rail 7 when the pawl 2 is pulled up in the front. In order to move the carriage 9 manually, therefore, the front part 21 of the pawl 2 must be slightly raised or turned upwards.
  • Such guide rails 7 are, seen in cross section, designed substantially rectangular, wherein they have on the bottom 8 facing away from the top of a slot which is wider than the pawl, however, narrower than the carriage 9 itself.
  • the carriage 9 is displaceable in the rail along the rail longitudinal axis and can not be removed forwards from the rail 8. The carriage 9 has to be pushed into the rail 7 from the side at a specifically provided insertion area.
  • the pawl 2 When inserted into the rail carriage 7 9, the pawl 2 can not be removed from the base body 1 even if the bolt is not present or broken -abgeschert- because the pawl 2 only by a sliding rotary motion, namely a rearward Sliding movement followed by a counterclockwise rotation could be removed from the slot 10, which is not possible for the reasons set forth below.
  • the carriage 9 Once the carriage 9 is inserted into the U-shaped rail 7, the pawl 2 can only slightly, that is pushed by a maximum of about 1 to 2 millimeters, to the rear.
  • the maximum possible rotation is limited by the cam 13 abutting the shoulder 13, while in the counterclockwise direction the maximum possible rotation is limited by the area of the rear part 22 of the locking pawl 2 which adjoins the cam 26 to the front.
  • the front part 21 of the pawl 2 is pulled in the case of load down, so that in the case of load, a rotation of the same in the counterclockwise direction anyway only a theoretically possible variant.
  • the pawl 2 is pulled by the force acting in the region of the elongated slot 24 downward force, which causes the back 22 a of the pawl 2 under the action of a large radial force on the bottom 8 of the rail. 7 applies, whereby the carriage 9 is locked immovably. At very high load, the pawl 2 can possibly penetrate to some extent in the bottom 8 of the rail 7.
  • the safety device performs its safety function by at least a part of the body weight of a person to be secured must be intercepted. This happens, for example, when a person loses his balance when climbing a ladder or slips off a rung. It is understood that the safety gear is designed so that it must be able to catch the entire body weight of a person to be secured.
  • the pawl 2 is usually pulled as far down or twisted until the cam 26 on the shoulder 13 for Plant comes.
  • the rear side 22a of the pawl 2 penetrates into the bottom 8 of the rail 7, which is usually made of aluminum.
  • the pawl 2 is made of a harder material than the guide rail 7, so that in the load case, only the bottom 8 of the rail 7 material plastically deformed. It is understood that the guide rail 7 must be replaced after a load case, at least in sections.
  • a very decisive advantage of the safety gear designed according to the invention is that the safety function of the safety gear is not impaired even in an extreme load case in which the hinge pin 5 should break or shear, since the pawl 2 does not come out of the longitudinal slot 10 of the main body 1 can be pulled out.
  • This is made possible by the combination of an appended to the paragraph 13 survey 26 and the forward rising lower wall portion 14a of the longitudinal slot 10, on which the lower end face 29 of the pawl 2 comes after a fracture of the bolt to rest.
  • this is achieved in that the clear height A of the slot 10 in the front region is smaller than the height B of the rear part of the pawl second
  • the pawl is not removable from the slot forward (pulled out)
  • the pawl is not removable without damaging the body and / or the pawl. It is understood that using appropriate force and related damage such as material plastic deformation of the pawl and / or the Basic body, the pawl can be removed. But this is not in the sense of the invention.
  • the pawl could be designed such that its rear part can not be pushed through the slot in principle.
  • the pawl would have to be inserted into the slot from the rear side of the base body, wherein the front part is dimensioned so that it can be pushed through the slot, while the rear part is higher than the slot, so that the pawl after the Inserting in the slot can not be pulled forward out of the slot.
