Definitions

  • the invention relates to a tool for driving in pins according to the preamble of patent claim 1.
  • a tool of this type is known from DE-B-1 250-379. It has a tubular housing that can be gripped with one hand, the cylindrical cavity of which is closed at the front by a disk provided with a guide hole for a pin.
  • a guide sleeve In the cavity there is a guide sleeve and a plunger is slidably mounted in it, which is adapted to the diameter of the pin to be driven in at the front and widened at the back.
  • the bore diameter of the guide sleeve is adapted to the plunger, i.e. H. smaller in the front part of the sleeve than in the rear part.
  • the rear end of the plunger is designed as a striking head, which is struck with a hammer (not part of the tool) to drive in the pin.
  • the hole in the wall is also widened by causing the pin to vibrate naturally with each stroke.
  • the tool has a tubular housing similar to a bicycle pump, in which a striking body with a handle and a plunger are arranged so as to be displaceable coaxially with a guide hole for the nail.
  • the plunger has a head which can be displaced to a limited extent in a bore at the lower end of the striking body, a rubber block or a spring being arranged in the region of this displaceability.
  • the tool is fixed to the floor by placing the foot on a base plate attached to the lower end of the housing, whereupon he holds the upper end of the housing with one hand and grips the handle with the other hand and pushes it down.
  • the impact body first moves downwards with the plunger when the spring is released until the plunger strikes the nail head.
  • the plunger initially remains at rest until the striker, which moves against the force of the spring, strikes the top of its cavity at the head of the plunger, so that the plunger strikes the nail into the floor.
  • the purpose of the rubber block or the spring is to dampen the impact of the plunger on the nail head so that burr formation at the end of the plunger is avoided. Precise driving in of a nail is also not possible with this tool, and there is also a risk of playful nailing. Because only the nail head, but not the nail shaft, is held laterally in the guide hole, the shaft at the entrance of the hole made in the floor can bend and expand.
  • the invention seeks to remedy this.
  • the invention specified in claim 1 solves the problem of creating a simple tool with which pens can be knocked into a hard wall without particular manual work, without damaging it (or the pen).
  • the outer end 4 of the guide sleeve 3 is closed and provided with a guide hole 5 through which the rear end 6 of a pin 7 to be punched into a wall can be passed.
  • the bottom 8 of the sleeve 3 is dimensioned accordingly thick, so that there is a sufficient length for the reliable guiding of the pin 7 of the guide hole 5.
  • the head 9 of a plunger 10 is displaceably guided, the shaft 11 of which is guided in a hole 12 in the housing 1, in the position shown, in which the head 9 abuts the bottom 8, into the interior 13 of the housing 1 somewhat protrudes.
  • the head 9 has a blind hole 14 coaxial with the guide hole 5 for the rear pin end 6.
  • the plunger 10 is loaded by a helical spring 15 supported between its head 9 and the edge of the hole 12.
  • Guide sleeve 3, guide hole 5 and plunger 10 are coaxial to the housing 1.
  • the end face at the outer end 4 of the sleeve 3 is slightly convex (convex), it can be provided with a (not shown) cover made of rubber-like material.
  • a striking body 16 is mounted such that it can be moved easily and, in its end position on the left (not shown) in FIG. 1, abuts the plunger shaft 11.
  • the striking body 16 consists of a solid cylinder 17, expediently made of iron, which has a plastic jacket 18 on which a handle 19 is formed at the outer end of the striking body 16.
  • the body 17 is approximately as heavy as the head of a hammer suitable for driving in the pins.
  • a pin 21 sits in the casing 22 of the housing 1 at its right end 23 in the drawing and engages in a longitudinal slot 24 of the casing 18, which ends shortly before the left end face 25 of the impact body 16 in the drawing, in order to completely pull it out of the casing To prevent housing space 13.
  • a ventilation hole 26 (or more) in the housing jacket 22 prevents the formation of an air cushion in the cavity 13, which would be very undesirable, particularly when the impact body 16 is pushed into it.
  • the end face 27 at the outer end of the cylinder 17 is provided with a stepped cylindrical recess 28/29, in the further part 29 a flat head plate 30 with a through hole 31 (FIG. 4) and in the narrower part 28 a head 32 with a blind hole 33 (Fig. 5) for a hammered pin 7 can be used in a slightly adhesive manner.
  • a blind hole 34 is located at the base of the narrower part 28 of the recess 28/29.
  • the head 32 with the blind hole 33 and, if desired, the head disc 30 with the through hole 31 beforehand can either be put onto the pin by hand or inserted into the recess 28 or 29 using the tool, in which case he or she then adheres easily and can be attached to the rear end of the pin with the help of the tool.
  • the hole 33 and 31 is dimensioned so that the z. B. PVC head 32 or the head disc 30 holds with a clamp on the pin 7.
  • FIG. 6 shows pins 7 without a head struck into a wall 36, with the head 32 and also with the head disc 30, the latter serving to fasten a drawing, a picture or a so-called poster 37 to the wall 36 and not at the same time to damage what is reliably achieved in the manner described.
