  • the present invention relates to a kit, according to the preamble of claim 10, for subsequently attaching a guide element to a nail setting device, comprising a base body on which attachment means are provided in order to be able to attach the base body to the base body of a nail setting device, and which has fastening means for a movable guide element, and a movable guide element fastened to this.
  • the present invention relates to a nail setting device according to the preamble of claim 14, in particular a pneumatic nailer, with a base body which comprises a barrel for guiding a nail to be driven into a workpiece and a striking pin driving said nail, wherein the barrel extends between a front free end, through which the nail emerges when driven into a workpiece, and a drive-side rear end, wherein the barrel forms a firing channel on the inside along a firing channel axis and has an open front end section in which it surrounds the firing channel only over a partial circumferential section.
  • Nails are among the oldest known fasteners in construction technology, such as house building, shipbuilding, armament technology, etc., mostly in connection with the material wood.
  • nails are driven into the material to be nailed with hammers. This usually requires several hammer blows, and there is a risk of the nail bending if the nail head is not hit in the extension of the nail shaft.
  • Conventional pneumatic nailers have a base body which comprises a barrel for guiding a nail to be driven into a workpiece and a firing pin which drives it.
  • the base body can form a device nose, particularly in the case of a modular pneumatic nailer, or be part of a device nose, to which a device for applying compressed air is connected at the back.
  • the barrel extends between a front free end, which is placed on the workpiece to drive a nail, and a rear drive-side end, which is fluidically connected to the device for applying compressed air, and forms a firing channel on the inside.
  • the firing pin is pressurized with compressed air by manually actuating a trigger or by automatically actuating it, so that it moves at high speed in the firing channel towards the free end of the barrel and drives a nail into a workpiece.
  • Pneumatic nailers of this type are particularly popular for driving in metal nails.
  • pneumatic nailers have also been increasingly used to drive wooden nails directly into components that are to be joined together without making a pre-drill.
  • nails are connected to form rigid or flexible nail strips so that the nails can be automatically fed into the firing channel one after the other.
  • the barrels of commercially available pneumatic nailers have an open front end section in which the barrel only surrounds the firing channel over a partial section of the circumference. Since wooden nails do not have the ductility of metal nails, the material bond breaks down when they hit a hard spot, so that the wood fibers contained in the wooden nail exert radial pressure on the barrel of the nailing device under the axial pressure of the firing pin due to their then no longer aligned structure. It has been found that this pressure can exceed the strength of the components of the nailing device, in particular the barrel and the firing pin.
  • Nail setting devices with a movable guide element of the type mentioned above are known, for example, from US 2009/ 007 2000 A1 , which Preamble of claim 1, which US 6 578 749 B1 and the EP 1 741 519 A1 previously known.
  • the object of the present invention is therefore to further develop a nail setting device of the previously known type in such a way that it is characterized by particular reliability and ease of use and in particular avoids the disadvantages mentioned above.
  • the nail setting device has fastening means which are designed and suitable for releasably fastening to the base body a movable guide element which can be pivoted about a pivot axis relative to the base body between a radially inner guide position with respect to the firing channel axis, in which it partially closes the open front end section of the barrel and guides a nail to be driven in and the firing pin driving it along the firing channel axis, and a radially outer deflection position in which a radial deflection of a nail to be driven in is possible.

  • the movable guide element has a linearly extending guide groove for guiding a nail to be driven in and a firing pin in an inner end face facing the firing channel axis when it is attached to the nail setting device.
  • a guide groove which preferably extends in the direction of the firing channel axis when the movable guide element is in its guide position, enables stable guidance of a nail to be driven in, which slides along the movable guide element when being driven into a workpiece.
  • the guide groove can have a V-shaped cross-section, with the opening angle being in particular at least 60° and/or at most 120°, preferably approximately 90°.
  • a V-shaped basic shape creates a two-point support for a nail with a circular cross-section. With an opening angle of 90°, the support points are also offset from one another by an angle of 90° on the contour of the nail.
  • the front surface which points radially inwards to the firing channel axis when installed, can have additional surface sections in addition to the guide groove.
  • a flat front surface section adjoins the guide groove on both sides, viewed from the center of the groove, with the two front surface sections lying in one plane in particular.
  • there can be chamfered slopes which can be inclined, for example, at an angle of 15° to the flat front surface sections.
  • the rear end of the guide groove opens into a central recess which completely passes through the movable guide element radially to the firing channel axis and separates two webs which protrude to the rear and lie opposite one another.
  • the central recess can be used to remove wood fibers which are released when a nail collapses, so that a subsequent nail can be driven in directly afterwards without first cleaning the free end of the firing channel and the movable guide element.
  • the width of the recess can be based on the diameter of the nail, in particular be larger than the diameter of the nail to be driven in and/or be approximately 6 mm. A rounding can be provided in the transition to the two webs which protrude to the rear.
  • the two webs can extend back to different distances.
  • inlet contours can be provided in the transition to the webs, which are preferably designed differently on both sides of the guide groove. Tests have shown that the asymmetry of the design of the webs and the inlet contours means that the firing pin cannot hit the movable guide element in an unfavorable manner when it slips off the nail head and be damaged there if the nail collapses. Due to the geometric asymmetry of the movable guide element in the area of the webs and the inlet slopes, damage to the various components can be reliably prevented.

  • Such a stepped inlet contour on one side of the guide groove can efficiently absorb high radial forces from a collapsing wooden nail. At the same time, the mechanical stresses on the firing pin and the barrel are minimized and plastic deformation of the components is avoided.
  • the transition between the front and rear inlet slopes can be rounded, with the rounding preferably having a radius of about 4 millimeters.
  • Such a rounding between the two inlet slopes prevents a sharp-edged transition and thus the risk of material blocking.
  • the front inlet slope and the rear inlet slope as well as a rounding formed between them can also extend at least partially into the area of the central recess and form a transition between the guide groove and the central recess.
  • the inlet contour can be designed as a single-stage inlet bevel on one side of the guide groove and can be inclined to the inner end face by an angle of at least 10° and at most 20°, preferably by 15°. It can thus be provided that one inlet contour is designed in several stages and the other inlet contour is designed as a single-stage inlet bevel. Such asymmetry means that damage to the firing pin and other components can be reliably prevented if a nail collapses and forces acting radially to the firing channel axis occur.
