Latest Patents

One of Tachihara's latest inventions is a nailer that features a wrenching portion in an adjuster designed for rotation. This gripping portion is polygonal in shape, which reduces the size and weight of the adjuster while enhancing its operability for adjusting driving depth. Additionally, an undercut portion is removed in a vertical direction, and a non-slip rugged portion is provided only in a longitudinal direction. This design allows for manufacturing in a simple two-part mold, thereby reducing production costs.

Another significant patent is a pneumatic fastener driving tool. This tool includes a main valve that alternately introduces and discharges compressed air into the upper piston chamber. It features a first passage leading compressed air into the main valve chamber, along with a repeat valve that opens and closes this passage. A second passage connects the lower piston chamber to a repeat valve chamber, where the repeat valve is reciprocably received. This construction allows the repeat valve to move in response to pressure changes, enabling reliable fastener driving without operational failures.
