Wall-Proximity Furniture Member Having Sync Mechanism

A furniture member includes a base assembly, a frame assembly, a legrest mechanism, a support rod, and a sync mechanism. The frame assembly is movable relative to the base assembly among an upright position, a partially reclined position, and a fully reclined position. The legrest mechanism is movable relative to the frame assembly between a retracted position and a fully extended position. The support rod is supported by the frame assembly. The sync mechanism is coupled to and supported by the support rod. The sync mechanism is configured to prevent the frame assembly from moving from the upright position to the partially reclined position until the legrest mechanism reaches the fully extended position.

System consisting of a camshaft and a camshaft sleeve

A system including a camshaft and a camshaft sleeve. The camshaft sleeve has a sleeve-shaped main body for receiving an end region of the cam-shaft. The main body includes a joining region, a bearing region and a seat region. The main body and the camshaft are configured in such a way that, in the mounted state, the cam-shaft is joined in the joining region to the camshaft sleeve, the system having, in the bearing region, a clearance between the camshaft and the camshaft sleeve, and the camshaft and the camshaft sleeve are connected to one another in the seat region via a positively locking means and/or a frictionally lock, in particular a toothing system.

Mechanically programmable closed fluid actuation system

Aspects of the disclosure relate to methods, apparatus, and systems for actuating a soft robot. An actuation system includes a camshaft, a motor configured to drive the camshaft to rotate around a rotational axis, and an air bladder configured to expel fluid from the air bladder during compression and draw fluid into the air bladder during decompression. The system further includes a cam coupled to the camshaft that is configured to rotate around the rotational axis when the camshaft is driven and compress or decompress the air bladder based on a physical profile of the cam as the cam rotates around the rotational axis. The system also includes a soft robot coupled to the air bladder, wherein the soft robot is actuated to move based on the fluid inserted into the soft robot during compression or the fluid removed from the soft robot during decompression.

Stamped metal outer cam for steering system

A rake adjustment assembly for a steering column system includes a rake lever that is rotatable. The rake adjustment assembly also includes a rake bolt operative coupled to the rake lever and positioned to selectively exert a clamping force to lock and unlock the rake position of the steering column system. The rake adjustment assembly further includes a cam assembly comprising an outer cam formed of stamped steel and press fit within a pocket defined by an outer face of the lever. The outer cam includes a main body. The outer cam also includes a plurality of legs extending from the main body.

Reciprocating pedals with dual-levered cam for asymmetric reciprocation
11175688 · 2021-11-16 · ·

A lift truck employs forward and reverse pedals connected through respective cams having different upper and lower cam profiles that engage to provide asymmetric reciprocal pedal motion. For example, first pedal depression causes a first cam upper profile to engage with a second cam upper profile and cause increased elevation of a second pedal, and first pedal depression causes a first cam lower profile to disengage with a second cam lower profile associated with the second pedal, such that first pedal depression is greater than the increased elevation of the second pedal.

Cam for a camshaft

A cam having at least two part cams are arranged axially behind one another along a longitudinal axis includes an undercut between the cam parts. The part cams have running faces which lie radially on the outside of the part cams and have different variable running face contours. The undercut has a profile with a variable contour which is dependent in each case on that adjacent running face contour which is at a smaller radial spacing from the longitudinal axis than the other running face contour.
