发明名称 Fastener driving apparatus
摘要 A fastener driving apparatus for driving fasteners into a substrate. The fastener driving apparatus is a combination of a motor driven linear motion converter; a compression cylinder; an expansion cylinder and a valve arrangement. The linear motion converter converts a rotational motion of a motor to a linear motion of a compression piston within the compression cylinder causing a gas within the compression cylinder to be compressed. The compressed gas is communicated to the expansion cylinder through the valve arrangement wherein the compressed gas expands causing an anvil coupled to an expansion piston within the expansion cylinder to move axially. The axial movement of the anvil causes a fastener to be driven into the substrate. The fastener driving apparatus is an ergonomically designed portable hand held tool providing comfort to a user, meeting safety standards and performance efficiency requirements.

主权项 1. A fastener driving apparatus, comprising: a power source; a motor electrically connected to the power source; a first cylinder comprising a first piston reciprocally movable within the first cylinder, the first piston defining a gas chamber within the first cylinder, the gas chamber capable of accommodating gas therein;a first cylinder end cap configured at a first end of the first cylinder, the first cylinder end cap configuring the gas chamber between the cylinder guide, the first piston and the first cylinder end cap, the first cylinder end cap having a hollow portion, a slider crank arrangement driven by the motor, the slider crank arrangement operationally coupled to the first piston and configured to cause the first piston to reciprocally move within the first cylinder; a second cylinder comprising a cylinder guide,a second piston disposed within the cylinder guide, the second piston having a front face and a rear face, andan anvil coupled to the rear face of the second piston, wherein the second piston is capable of linearly moving within the cylinder guide, thereby enabling the anvil to move in a driving direction; and a valve arrangement operationally disposed between the first cylinder and the second cylinder, the valve arrangement defining a gas passageway for communicating the gas from the first cylinder to the second cylinder and the valve arrangement capable of assuming one of an open position and a closed position; wherein the gas received within the gas chamber is compressed by the first piston in a single stroke of the slider crank arrangement in a manner such that the compressed gas is communicated into the second cylinder through the gas passageway of the valve arrangement, causing the compressed gas to expand in the second cylinder thereby causing the second piston to move linearly and enabling the anvil to drive a fastener into a substrate in the driving direction in the single stroke of the slider crank arrangement.
