Definitions

  • the invention relates to a device according to the preamble of claim 1.
  • Workpieces e.g. Building hardware usually has pre-punched holes through which fasteners, e.g. Nails are driven into the wall, the beam or the like. This driving can be done by hand with a hammer.
  • fasteners e.g. Nails are driven into the wall, the beam or the like.
  • This driving can be done by hand with a hammer.
  • well-known, e.g. operated fastener driving tools used they are known from DE-OS 23 50 859.
  • With relatively thin workpieces e.g. Building hardware with a thickness less than 2 mm can drive the fasteners through the sheet metal material of the fittings without the need for perforation. With thicker fittings, however, the force of the driving tools is usually not sufficient to secure the fasteners, e.g. a nail to drive through the material.
  • workpieces e.g.
  • Construction hardware is necessary, which is provided with holes or at least thinning at predetermined locations.
  • driving-in devices the problem arises here of positioning the driving-in device with the driving-out channel exactly above the perforation or the like of the workpiece, so that the fastening means is driven precisely through the perforation into the substrate.
  • the object of the present invention is to propose a simple and reliable positioning device for a fastener driving device of the known type.
  • the solution principle according to the invention is therefore based on the idea that e.g. to provide ring-shaped positioning elements which in the positioning position at least partially protrude into the region of the drive-out channel, which corresponds to its diameter approximately to the diameter of the perforation of the workpiece, so that the positioning elements in this position can snap into the perforation with their front ends, which the user of the driving tool, and that these positioning elements can then be moved at least by radial outward movement from the area of the driving channel, so that the latter is opened for driving out the fastening means.
  • the invention thus differs from an older proposal, in which on a fastener driving device the fastener was provided with an additional, relatively complex pneumatic control system, with which the front end was only slightly pushed out of the driving channel before the fastener was actually driven out, so that this front end itself could be used to position the driving tool over a hole.
  • the positioning elements are thus in their front positioning position, at least with their ends protruding from the device mouthpiece in an assembled position Position, while in their axially retracted release position a radial movement apart of these ends previously protruding into the expulsion channel is possible.
  • the driving tool with the positioning elements is guided over the workpiece until the positioning elements snap into the desired perforation, then the positioning elements are axially moved back from the positioning position to the release position, in which they can then move apart radially.
  • the positioning elements move automatically again from their release position into the positioning position after use of the driving tool, so that the driving tool is ready for a new use.
  • Claim 4 provides a convenient and reliable mounting of the positioning elements in the device mouthpiece.
  • the positioning elements in their front positioning position due to the interacting inclined surfaces are necessarily joined at least at their front ends, so that they form with their ends protruding from the mouthpiece of the desired outer cross-section matching the holes, while in the axially retracted release position, the positioning elements move freely radially outwards and can thus release the previously hidden expulsion channel.
  • the further embodiment according to claim 7 has the particular advantage that the positioning elements in their release position by the fastening means, e.g. the nail driven through the expulsion channel are spread apart.
  • the feature of claim 8 ensures that the device according to the invention can be used for different hole cross-sections without any problems, since perforations which lie in a certain diameter range can be scanned due to the conical tip formed by the positioning elements.
  • a securing nose is known on driving tools of the type mentioned at the outset, which is displaced axially against a spring force when the driving tool is placed on the workpiece, so that the actuating device of the driving tool is only released thereby. This is intended to avoid wanton actuation of the driving tool and accidents, since the fastener can only be driven out when the driving tool is really placed on a workpiece.
  • this known safety lug is now shortened compared to the known designs, i.e. it does not protrude to the front end of the device, but interacts with a rear surface of the actuating elements or the actuating cylinder.
  • the spring element which is present anyway for the securing lug, is advantageously also used for the positioning device according to the invention, and the securing lug and positioning device are actuated simultaneously.
  • a simple assembly of the device according to the invention is possible. First of all, from the rear open, extended end, for example, the bottom sitioning cylinder with the inserted positioning elements inserted into the tapered mouthpiece. This can then be screwed onto the device body or part of it. In this way, an exchange of the positioning device for a different dimension is possible without difficulty.
  • a special securing of the positioning device is provided in the mouthpiece.
  • the his principle according to known pneumatically operated N ageleintreib réelle 1 of Figure 1 has a in a pressure cylinder 28 to the actuation of an actuating device 27, consisting of lever and pressure inlet valve, axially displaceable piston 5 on which a guided in a drive-out 6 driving pin at its front end. 7 has. 1, the piston 5 is currently in its lower driven position, in which a nail 4 is driven through a hole 2 in a workpiece to be fastened to a beam 29, for example building hardware 3.
  • the front end of the driver pin 7 lies above a nail magazine 30 which opens laterally into the drive-out channel 6 and from which nails which are arranged diagonally side by side are pressed individually into the drive-out channel 6 under spring pressure.
  • a sleeve-shaped device body part 24 provided with an external thread 31 is now attached to the front end of the device section forming the expulsion channel 6.
  • a device mouthpiece 8 is screwed onto this device body part 24 with its enlarged rear end 23.
  • a positioning cylinder 12 which is adapted to the internal dimensions of the device mouthpiece 8, is guided axially displaceably. With its axial bore 11, it forms part of the expulsion channel 6.
  • the positioning cylinder 12 becomes from a protruding from the sleeve-shaped device body part 24 securing lug 21, which acts on a rear surface 22 of the positioning cylinder 12 under spring force, pressed into the front tapered section of the device mouthpiece 8, so that the positioning cylinder 12 protrudes with its front end from the device mouthpiece 8.
  • the mounting cylinder 12 is by means of a parallel to ustreibkanalachse A
  • a pin 26 which is fixed to the apparatus body part 24 and engages in an axially parallel recess 25 of the positioning cylinder 12, secured against rotation in the device mouthpiece. 8
  • the positioning cylinder 12 has four radial slots 10 offset at 90 °, which merge into radially extending deeper recesses 17 at the rear end.
  • Positioning elements 9 with rear hook sections 16 are each pivotably suspended in the radial recesses 17 so that they are guided in the slots 10 and with their respective front section 18 in the axially front positioning position of the positioning cylinder 12 shown in FIG Expulsion channel 6 protrude.
  • the positioning elements 9 are thereby pressed under the spring force acting on the securing lug 21 and transmitted to the positioning cylinder 12, because the positioning elements 9 each lie on an inner complementary inclined surface 15 of the device mouthpiece 8 with an outwardly facing inclined surface 14.
  • the radial recesses 17 and the slots 10 are dimensioned such that the positioning elements 9 are pivoted into the combined positioning position shown in FIG. 2a under the action of the spring force mentioned.
  • the positioning elements 9 at their front end 13 protruding in the positioning position from the device mouthpiece 8 each from the rear outside to the front inside have inclined surfaces 20, the positioning elements 9 form a conical tip in their positioning position, which can be inserted into the perforation 2 of a workpiece 3, so that a secure positioning of the driving tool 1 over this perforation 2 is possible.
  • This radial pivoting apart of the positioning elements 9 is achieved in that the fastening means, namely the nail 4, when driven out, meets the inner engagement surfaces 19 of the positioning elements 9 which run obliquely towards one another towards the tip of the device mouthpiece 8, and thus pushes the front sections 18 apart. This position with the nail 4 fully expelled is illustrated in FIG. 3.
  • the securing lug 21 which was axially pushed back into the hole 2 when the positioning elements 9 were inserted, pushes the positioning cylinder 12 including the positioning elements under the action of the spring force 9 in the axial direction forward so that under the we Kung the inclined surfaces 14 and 15, the positioning elements 9 are brought together with their front portions 18 so that the inclined surfaces 20 again form the desired conical tip.
  • the positioning device is now ready for a new use.
