Definitions

  • the invention relates to a powder-powered setting tool for driving in fasteners, such as nails, in substrates, with a mouth part which can be moved from a front position backwards to the ignition-ready position, a guide profile projecting 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 mostly being compressed.
  • the invention has for its object to provide a pressure protection the triggering of an ignition process is excluded if there is no fastening element in the muzzle bore.
  • FR-A-277 653 relates to a bolt-setting tool with a nail magazine on the front barrel part which can be pivoted about an axis lying parallel to the barrel. If the nail magazine is in the swung-out state, ignition of the device must be prevented for safety reasons. Due to the arrangement of a locking member, the feed channel can only be swiveled into the forward position of the barrel.
  • EP-A-100 105 relates to a nail magazine for nail devices. When the magazine is empty, a blocking element is moved over the slide. This blocking element engages around the displaceable mouth part and prevents it from plunging backwards into the device and thus getting into the ignition-ready position.
  • the object is achieved in that the slide has a stop shoulder projecting into the axial projection of the end face of the housing in the end position, which is formed by the end face of the slide facing the housing and which moves the front end of the housing into an ignition-ready position by a Cutout in the guide channel of the guide profile is prevented.
  • 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 slider 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 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 it can be conveniently removed from the side or 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 from external damage in the box-shaped guide profile, so that trouble-free function 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 initial position into the end position is provided.
  • 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 position of the setting device 1 in the effective range of an ignition element which can be triggered 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 that closes the latter.
  • 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 the feed direction of the slider 15 overlooked by a feed nose 21.
  • the feed lug 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 oriented longitudinally in the base body 11 projects into the niche thus created along the section 26 and holds the fastening elements 22 axially defined in the guide profile 8.
  • the housing 2 moves relative 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.
