摘要:
The indirect-firing apparatus includes a combustion chamber for a cartridge (62), a trigger for igniting the cartridge, a barrel, an inertia block in the barrel, an anchor guide (7) designed to receive an anchor, a shuttle (34) in the anchor guide (7) mounted for movement from an anchor loading position to a position for firing and driving of the anchor, mechanisms (63, 11, 46) for displacement of the shuttle from one position to the other, and a barrel holder (61) for concomitantly controlling the closure of the combustion chamber (3) and means for displacement of the shuttle (34). The mechanisms (63, 11, 46) for displacement of the shuttle (34) are arranged so as to drive the shuttle (34) beyond the firing position (25). Damping components (33, 38), when the shuttle (34) has reached its firing position (25), absorb the action of the displacement mechanisms (63, 11, 46).

The tool is to be used for driving fastening members into a supporting material. It comprises a cylinder (3), with a piston (5), a combustion chamber (1, 11), a cylinder head (12) bearing a fuel igniting means (36) in the chamber (1), a pin guide (9), for receiving a fastening member and the piston (5) shaft (7) and a cage (21). Return means are provided for opening the chamber (11), driving the pin guide (9) forwardly, opening and closing abutment means for the chamber (11). There are provided: one single central spring (32) for opening the chamber (11) and, on each side of the tool, one single opening and closing side chamber abutment (18, 55), integral with the chamber (11) and mobile in translation on the corresponding side of the cylinder (3).

A gas setting tool, wasting a limited amount of fuel. The tool comprises i) an internal combustion engine, with a device for injecting fuel in the chamber of the engine, comprising a check valve and an injection piston, the injection piston extending beyond the check valve, and iii) a sealing joint mounted on the injection piston of the check valve. The injection piston comprises an internal bore opened on the exterior and the check valve and its injection piston are arranged so that, in an opening position, the fuel in a container is able, outside the check valve, to only flow through the internal bore of the injection piston. Thanks to this invention, fuel waste is reduced to the best.

The tool comprises an engine for propelling a piston including a shaft for driving a fastening member into a supporting material and through a pin guide, with means for adjusting the depth of drive of the piston shaft outside the pin guide at the end of the propulsion and at the stop of the piston in abutment against stop means. The pin guide is mounted free in translation and the depth of drive adjusting means comprise an adjustment knurl with a knurl shaft arranged so as to be in abutment against the pin guide and to push the pin guide forwards under the rotation action of the knurl.

The apparatus comprises a removable magazine for the supply of fasteners, designed to contain a strip of fastener-holding rings, a fastener-guide (3) and a unit (4) for shearing the strip of fastener-holding rings, and which is functionally a single unit. The shearing unit (4) and the fastener supply magazine are adapted to work together to house a skirt (11), integral with the shearing unit (4), forming a passage (12) for fastener input, in a reception compartment of the skirt (11).

The pole comprises a securing end, with device securing means and the device actuating means, a gripping end to be gripped by an operator and telecontrolling means for telecontrolling the actuating means. The actuating means are arranged in the device securing means and are directly controlled by the securing end of the pole and thus telecontrolled by the pole and its gripping end under the action of a thrust of the pole towards the support material. The device actuating means comprise safety means arranged to avoid by gravity the control of the actuating means by the securing end of the pole when the spatial position of the pole is inappropriate. The invention also relates to an anchoring device provided with the same safety means.

The tool comprises an assembly of a tip-guide and a shear unit, on which can be fastened a charger of fastening elements. The fastening elements are introduced in the bore of the tip-guide through a passing window provided in the shear unit. The tool comprises a pivoting flap for adjusting the effective length of the passing window to the length of the fastening elements to be driven. The flap is pivotally mounted about an axis substantially parallel to the tip-guide bore and is adapted to provide a guiding surface for the shortest fastening elements before they enter the partially plugged passing window. With the invention, the short elements can neither rock the tool nor jam it.

In the assembly of the invention, the assembly includes adapter means designed to connect the transmission member and the energy source and to ensure good transmission of energy between them. The adapter means comprise means for locking the energy source in rotation in the device and means for the angular indexing of the source in the position in which it is locked in rotation in the device. The invention is very suitable for gas fastening devices.
