Definitions

  • the invention relates to a powder-powered setting tool for driving in fasteners, such as nails, in substrates, with a mouth part that can be moved from a front position backwards to the ignition-ready position, a guide profile that projects laterally over the mouth part with a slide for advancing the fasteners from the guide profile into the Mouth bore, the slide being displaceable from an initial position into an end position freed from the fastening elements.
  • Known powder-operated setting tools generally have a pressure lock, which ensures that the propellant charge can only be ignited if the mouthpiece of the device is pressed against a surface in the setting direction.
  • the mouth part can be shifted backwards into a ready-to-ignite position in a housing, the tension spring of an ignition mechanism known per se usually being compressed.
  • the object of the invention is to provide a pressure protection device which the triggering of an ignition process is excluded if there is no fastening element in the muzzle bore.
  • the object is achieved in that the slide, in the end position projecting into the axial projection of the end face of the housing, displaces the mouth has part in the ready-to-fire stop shoulder.
  • the slide In the end position freed from the fastening elements, that is to say when the last fastening element has also left the mouth bore, the slide is located with a stop shoulder in the axial projection and thus in the displacement path of the end face of the housing. If the housing is pressed against the ground in this state, the housing only moves relative to the mouth part until the end face of the housing comes up against the stop shoulder. This only slight displacement is not sufficient to get the ignition ready.
  • This can be achieved, for example, in that a pin-shaped projection runs onto a stop shoulder of the slide lying outside the guide profile.
  • the guide profile can be open, with a substantially U-shaped cross section, or can be designed as a closed box profile.
  • the slide is advantageously supported on the bottom of the guide profile in the setting direction.
  • the stop shoulder is advantageously formed by the end face of the slide facing the housing.
  • the use of this end face as a stop shoulder makes separate measures unnecessary, so that this is a particularly simple form of the slide.
  • the stop shoulder is preferably formed by the region of the end face of the slide exposed by a box-shaped guide profile towards the housing.
  • the box-shaped guide profile has a window-like recess for the housing in the axial projection of the end face of the housing.
  • the box-shaped design of the guide profile offers safe and protected guidance of the fastening elements. To load the guide profile with fasteners, this can be conveniently removed from the side open or swing open a side wall. In the open position, the slide can also be returned to its starting position. The stop shoulder of the slide is protected in the box-shaped guide profile from external damage, so that trouble-free operation is guaranteed.
  • the stop shoulder is surmounted in the feed direction of the slide by a feed nose for the fastening elements.
  • the feed nose can be offset in relation to the stop shoulder in the setting direction.
  • a spring element driving the slide from the starting position into the end position is provided in a development of the invention.
  • the spring element can be designed as a tension or compression spring.
  • the setting tool shown in FIG. 1, designated overall by 1, has a housing 2 with a laterally protruding handle 3 and a trigger 4 assigned to it for triggering the ignition of a powder propellant charge.
  • the powder propellant charge sits in a bearing opening of a barrel and is in the ready-to-fire position of the setting tool 1 in the effective range of an ignition element which can be controlled by the trigger 4.
  • the housing 2 is protruded in the setting direction by a mouth part 5, which can be shifted backwards from the rest position shown in FIG. 1 into the ignition ready position shown in FIG. 3.
  • An orifice bore 6 leads to a hint which can be identified, which can be accelerated forward by the application of powder propellant gases in the orifice bore 6.
  • the mouth part 5 is assigned a box-shaped guide profile, designated 8 overall, in a fixed position.
  • the guide channel 9 of the guide profile 8 opens laterally into the mouth bore 6.
  • the guide profile 8 consists of a base body 11 with a U-shaped cross section and a removable side wall 12 with an L-shaped cross section closing it.
  • the side wall 12 is fixed to the base body 11, for example by snap connection in a manner known per se.
  • On a rear wall 13 of the base body 11 is supported, for example, a compression spring 14 made of strip material, which acts on a slide generally designated 15.
  • the slide 15 is mounted on guide rails 16, 17 in the guide channel 9 laterally.
  • the end face 18 of the guide bar 17 facing the housing 2 forms a stop shoulder 19 with a region on the feed direction side.
  • the stop shoulder 19 is in advance Direction of the slide 15 overlooked by a feed nose 21.
  • the feed nose 21 acts on a series of fastening elements lined up next to one another, identified overall by 22.
  • the fastening elements 22 each consist of a nail 23 and a guide bushing 24 made of plastic, as shown in FIG. 2.
  • circular guide rings 25 are provided in the axial projection of the fastening elements 22.
  • the axial section 26 between the guide rings 25 has a radially recessed outer contour.
  • a support bar 27 which is longitudinally oriented in the base body 11 projects into the niche formed along the section 26 and holds the fastening elements 22 axially defined in the guide profile 8.
  • the housing 2 shifts in relation to the mouth part 5 in the setting direction and thereby dips with its front end through a recess 29 into the guide channel 9 of the Guide profile 8.
  • the feed of the fasteners 22 into the mouth bore 6 is not hindered by the pressing process.
  • the ignition readiness is reached, so that the setting process can be triggered.
  • the piston 7 runs onto the fastening element 22 located in the orifice bore 6 and drives the nail 23 into the substrate 28, destroying the guide bush 24. After the piston 7 has subsequently been returned, the next fastening element 22 enters the orifice bore 6.
