摘要:
The invention relates to a hand-held or semi-stationary setting device for driving fastening elements into a substrate with the aid of a power piston, said device comprising an attachment device at one discharge end. In order to simplify the operation of a hand-held or semi-stationary setting device, waste gas leaving a combustion chamber is used during a setting operation to pre-stress the attachment device against the substrate.

An improved tool for installing an explosively driven fastener as well as an improved explosively driven fastener for use therewith are disclosed. The fastener includes a nail having a head with an explosive load attached thereto in a plastic cap that includes a buffer. The tool has a plurality of concentric cylinders and springs including a muzzle for receiving the fastener head and explosive load. A spring actuated firing pin ignites the load causing it to explode and drive the nail out of the tool. The explosion also automatically resets the tool. The tool and the fastener provide many advantages over existing explosively driven fasteners and the tools used to install them.

An adapter is provided that includes a housing, a striker, a spring, a lever, and a hook. The striker is movably mounted in the housing and biased by the spring towards a firing position with a front end extending into an aperture at the front of the housing. The lever is pivotally connected to the exterior of the housing and the hook. The hook extends through an aperture in the housing and is connected to the striker such that movement of the lever will move the striker. The front end of the housing has a connector for connecting the housing to a rear end of a powder actuated connecting tool.

A nailing machine includes a body, a nose extending from the body and having a nail guide channel therein, a driver reciprocally movable within the nail guide channel for driving the nail, and at least one first surface and at least one second surface formed on the end portion of the nose. The first surface extends perpendicular to the longitudinal axis of the nail guide channel. The second surface is formed in continuity with the first surface and is inclined at a predetermined angle with respect to the first surface.

An explosive powder charge operated fastening element setting device includes a housing supporting a handle. A damping unit is arranged between the handle and the housing so that the handle is displaceable in the setting direction of the setting device against a force developed in the damping device. A fastening element guide is mounted in the housing for movement opposite to the setting direction against a spring force. The force of the damping unit is greater than the spring force. The damping unit includes a cylinder containing a first fluid medium acting on a piston pressing, outside the cylinder, against the housing with a second fluid medium within the cylinder pressurizing the first fluid medium.

A sleeve-like holding member is positioned within the housing of an explosive powder operated gun-like setting device for gripping the fastening element before it is propelled from the housing. The holding member has at least one axially extending slot so that it is radially expandable against its own inherent tension. When a plurality of slots are provided, they are spaced angularly apart and extend from one end toward but short of the other end of the holding member. Adjacent slots extend from different ends of the holding member.

A noise reducer for a powder actuated fastening tool comprises a barrel including inner and outer cylindrical walls which are radially spaced to define a gas expansion chamber between them. The chamber is adapted to receive combustion gases through ports or passages in the inner wall, and the gases may be exhausted from the chamber in any appropriate manner, preferably at a location adjacent the front end of the tool. The outer wall of the barrel can thus be made to slidingly fit within the tool receiver, while porting of the expansion chamber can be such as to induce a favorable flow pattern to the combustion gases passing therethrough.

A pole extension device for use with a powder-actuated tool. A cam-equipped handle is twistably mounted on the end of a hollow elongate body. An inelastic cable is disposed within the body engaging the tool firing mechanism and attached to a pin riding on the cam, such that twisting of the handle, relative to the body, results in discharge of the tool.
