Definitions

  • the invention relates to a powder-powered setting tool with a barrel, a guide box projecting laterally from the barrel for a nail strip that can be fed into the barrel bore through a lateral insertion opening of the barrel and is spring-loaded in the feed direction.
  • a powder-operated setting tool is known, the barrel bore on the mouth side is supplied with a nail strip consisting of a carrier and nails held therein through an insertion opening.
  • the nail strip is slidably mounted in a guide box projecting laterally from the barrel and is acted upon by a spring on the longitudinal side via a slide mounted in the guide box.
  • a driving piston which can be displaced in the barrel bore, the nail supplied to the barrel bore is separated from the carrier and driven into a subsurface.
  • the spring and the slide To load the guide box with a new nail strip or to remove a partially used nail strip from the guide box, the spring and the slide must be brought out of the way of the guide box, which leads to complex handling.
  • the invention has for its object to provide a setting tool of the type mentioned that allows easy loading and unloading with loading strips.
  • the object is achieved in that, diametrically to the barrel bore, opposite the insertion opening, a loading opening is provided in the barrel which essentially corresponds to the longitudinal projection of the nail strip, in the projection of which a stop can be pushed in radially up to at most the contour of the barrel bore.
  • the loading opening allows nail strips to be inserted into the guide box through the insertion hole, the insertion being carried out against the force of the spring in the guide box. Nail strips can also be removed when the stop is disengaged.
  • the spring ensures automatic ejection. After a nail strip has been pushed in completely, the stop is engaged and thus holds the nail strip in the correct position against the force of the spring, ie the nail that is in the feed direction of the nail strip is in the axis of the barrel bore.
  • This device design is suitable for nail strips, the supports of which each consist of a nail-holding section, which are separated from the rest of the nail strip together with the respective nail by means of the driving piston. Nail strips can also be used, from whose support the nails are ejected.
  • the barrel advantageously has a stop means supporting the stop in the engaged position.
  • the stop means designed, for example, as a wall part of the barrel, the engagement movement of the stop is limited and the engagement position is reliably maintained.
  • the stop is preferably arranged on a pivot lever mounted on the barrel. This arrangement of the stop permits a construction of the device area accommodating the barrel that is compressed in the longitudinal direction of the barrel.
  • the pivot lever is expediently designed with two arms, one arm having the stop and the other arm having a support shoulder for the stop means.
  • the swivel lever thus fulfills a double function in that in one swivel position the support shoulder is engaged with the contour of the barrel bore and the support shoulder is removed from the stop means in the other swivel position lies and the stop is outside the projection of the loading opening. To release the loading opening, the stop can move into the barrel bore by swiveling the swivel lever.
  • a spring means which drives the stop in the engaged position is preferably provided. Against its force, the spring means allows the stop to be disengaged by pivoting the pivot lever when a nail strip is inserted through the loading opening into the device. After the nail strip has been pushed in completely, it releases the stop for returning to the engaged position, the return taking place automatically with the aid of the spring means.
  • the spring means holds the swivel lever in this position under the cooperation of the support shoulder with the barrel-side lifting means.
  • the setting tool shown in Fig. 1 has a housing 1 with a side handle 1a and a trigger 1b.
  • a barrel 2 with a barrel bore 2a protrudes from the housing 1.
  • a drive piston 3, which is indicated in the rear position, is mounted in the barrel bore 2a and can be displaced in a manner known per se by powder force towards the mouth of the barrel 2.
  • a laterally projecting guide box 4 is firmly inserted.
  • the inside of the guide box 4 opens into an insertion opening 2b passing through the wall of the barrel 2.
  • a slide 5 is attached orders, which is acted upon by a spring 6 to the bore 2a.
  • the spring 6 is supported, facing away from the slide 5, on the wall of the guide box 4.
  • the insertion opening 2b is opposite a loading opening 2c diametrically to the barrel bore 2a.
  • a pivot lever 7 is pivotally mounted about a bearing pin 8.
  • One arm of the pivot lever 7 is formed with the free end as a stop 7a.
  • a second arm of the pivot lever 7 carries a support shoulder 7b which cooperates with a stop means 2e in the form of a nose on the barrel 2.
  • a spring means 9 in the form of a torsion spring holds the swivel lever 7 with the stop 7a in the position according to FIG.
  • a nail strip 11 is inserted into the guide box 4.
  • This consists of guide bushes 11a, which are connected to one another via burstable webs 11b.
  • a nail 11c is located in each guide bush 11a.
  • the nail strip 11 is displaceably guided in the longitudinal direction in the guide box 4 and is pressed by the slide 5 against the stop 7a, as is illustrated in FIG. 1 by an arrow.
  • a nail 11c fed in this way to the running bore 2a is held by the stop 7a coaxially to the running bore.
  • the driving piston 3 By actuating the setting tool, the driving piston 3 runs against the nail 11c located in the barrel bore 2a and drives this, while separating the associated guide bushing 11a from the remaining part of the nail strip 11, through the mouth of the barrel 2 into an underground. After returning the driving piston 3, the spring-loaded slide 5 brings the remaining nail strip 11 into contact with the stop 7a for the next setting process.
  • FIG. 2 shows the insertion of a nail strip 11, as indicated by an arrow, through the loading opening 2c into the setting tool.
  • the swivel lever 7 pivoted against the force of the spring means 9 according to the rotary arrow and thereby brought the stop 7a out of the projection of the loading opening 2c.
  • the insertion-side end of the nail strip 11 runs against the slide 5 and brings it into the tensioned position against the force of the spring 6.
  • the pivot lever 7, driven by the spring means 9 reaches the position shown in FIG. 1 with the stop 7a engaged.
  • Any removal of a nail strip 11 from the setting tool is also carried out by actuating the swivel lever 7 according to FIG. 2.
