Definitions

  • the invention relates to a driving tool for fasteners which can be anchored by driving in.
  • Such fasteners can be designed as a nail without an expansion area, which are driven directly into the anchoring base, for example wood, gas concrete or the like, without pre-drilling.
  • nailable fasteners with an expansion area are used, which are anchored by driving them into a hole made in the anchoring base.
  • the fasteners are usually driven in by hammer blows that are applied directly to the nail head.
  • Driving tools with a flat face are used when setting the fastening elements in unfavorable places or when setting them mechanically with a rotary hammer.
  • the flat striking surface very often causes the driving tool to slip or tilt on the nail head, so that the impact energy does not act centrally on the fastening element. This results in bumps and damage to the fastener, which prevents the fastener from being properly placed.
  • attaching the fastener to hard-to-reach places is difficult or impossible since there is no possibility of holding the fastener.
  • the invention has for its object to provide a driving tool for fasteners which can be anchored by driving in, with which a correct setting of the fasteners is made possible even in hard-to-reach places.
  • the centering hole in such a way that a funnel-shaped section extends from the end face of the head of the fastening element and is adjoined by a cylindrical hole.
  • the fastening element can also be held in a horizontal position with the driving tool and easily attached to a wall.
  • a centering hole designed in this way is suitable for attaching a cover cap to the head of the anchored fastening element.
  • the driving tool For a mechanical setting of the fastening elements with a hammer drill, it is expedient to provide the driving tool with a clamping shank that fits into the receptacle of the hammer drill.
  • a further embodiment of the invention provides that the centering pin which engages in the centering bore of the fastening element is arranged on a plunger which is rotatably held on the shaft of the driving tool.
  • the centering pin can additionally be designed such that it engages in a clamping manner in the centering bore in the head of the fastening element.
  • the plunger For mounting and axially securing the plunger against falling out, it is expedient that the plunger, with its end facing away from the centering pin and having a constriction, lies in a central inner bore of the shaft of the driving tool and is arranged by flanged edge arranged on the front end of the shaft and projecting into the constriction, Circlip or the like is axially secured.
  • the fastening element 1 has a shaft with an expansion area 2 and a head 3.
  • the expansion area is formed by a longitudinal notch 4, the side flanks 5 of which are bent radially outwards to form expansion legs.
  • the fastening element 1 can be anchored by driving it into a borehole 6 of a component 7.
  • a centering bore 10 is made in the head 3 of the fastening element 1, into which the centering pin 11 arranged on the face 9 of the driving tool 8 engages.
  • the centering bore 10 and the centering pin 11 can be designed to taper for better centering.
  • the centering bore 10a has a funnel-shaped section 12, starting from the end face of the head 3 of the fastening element 1, to which a cylindrical bore 13 is connected.
  • This design of the centering hole 10a makes it possible to hold the fastening element 1 in a horizontal position with the driving tool 8a after the attachment.
  • the centering pin 11a on the driving tool 8a is adapted to the centering bore 10a with a conical section 14 which is extended with a cylindrical section 15.
  • the driving tool 8a is designed with a clamping shank 16 that fits into the receptacle of a hammer drill.
  • FIG. 3 shows the fastening element 1 anchored in the borehole 6 of the component 7 with a centering hole 10a according to FIG. 2.
  • This centering hole is suitable for fitting a cover cap 17, which for this purpose has a pin 18 which fits into the centering hole 10a.
  • FIG. 4 shows a two-part driving tool 8b with a clamping shank 16, which has a central inner bore 19 with a flat base 20 on its front end region.
  • the end of the plunger 21 facing away from the centering pin 11a is inserted in such a way that the plunger 21 can rotate relative to the clamping shaft 16.
  • the front end of the clamping shaft 16 has a flanged edge 22 which engages in the constriction 23 of the plunger 21.
  • the centering pin 11a protruding from the striking surface 9 of the plunger 21 engages, for example, by a slight oversize in the centering bore 10a of the fastening element 1 a. As a result, the plunger 21 is prevented from rotating by the fixed fastening element 1 during the driving-in process.
