摘要： A linear stage having a screw-nut assembly is actuated by the rotational motion of the screw. A mechanism, which is an integral part of the nut, quickly disconnects the screw and the nut, allowing rapid positioning of the linear stage in both the forward and reverse direction. The motion of said stage has a resolution given by the thread pitch of the screw and the nut; and a travel only limited by the length of the screw. The quick disconnect screw-nut assembly mechanism described in this invention is achieved by axial preloading said nut and allowing said nut to pivot perpendicular to the axis of said screw. Two or more linear stages having said screw-nut assembly are concatenated with one another to form a multi-axis positioning device.

摘要： An electromechanical latching system for locking a cabinet door and the like is disclosed. The latching system includes a motor drive that may include a gearbox. The motor drive selectively rotates a screw. In one embodiment, the screw engages a threaded opening of a pawl and the screw is used to pull up the pawl against, for example, a doorframe to secure, for example, a door against the doorframe. In another embodiment, the screw engages a threaded opening of an actuating arm such that rotation of the screw linearly moves the actuating arm along the length of the screw. The actuating arm engages an operating rod that operates one or more pawl assemblies to engage or disengage respective keepers.

摘要： An electric actuator comprises a gear mechanism which transmits the rotary driving force of a rotary driving source, and a ball spline mechanism which includes a ball spline shaft provided movably back and forth from a connecting block to the outside and which converts a rotary motion transmitted by the gear mechanism into a rectilinear motion. The electric actuator has a ball spline nut which is externally fitted to the ball spline shaft to be meshed with the gear mechanism and which is integrally formed with a gear section having a plurality of teeth circumferentially.

摘要： The invention relates to a furniture drive (2) for adjusting parts of a piece of furniture in relation to one another which is configured as a dual drive. Said drive comprises two drive units (4, 4null), every drive unit (4, 4null) being provided with a linearly displaceable drive element that is functionally linked with a pivoted lever for pivoting said lever in the mounting position of the furniture drive. Said pivoted lever in turn is functionally linked with a part of the piece of furniture to be adjusted. The drive according to the invention is further characterized in that the linearly displaceable drive element or a support element (24) linked therewith is provided with a support surface (26) for supporting the pivoted lever (18) in a position remote from its pivot axis (16) in the mounting position of the furniture drive (2), which surface is inclined with respect to the axis of motion (29) of the drive element. The inventive furniture drive (2) is simple in design and therefore inexpensive, it is furthermore advantageous in that it is very compact.
