Sprags having lower end portions are each inserted into the second apertures, central portions are each inserted into the first apertures, and upper end portions are in contact with the interior circumference of the sprag limiter, and allow the shaft hub to rotate in one direction based on the pulley movement.

A compensation coupling includes a first coupling half and a second coupling half, which may be fitted into one another under elastic deformation. The first coupling half has spring claws and the second coupling half has a toothing. The spring claws and the toothing have different pitches. A print bar for inkjet printing includes the compensation coupling.

A rotating mechanism includes a stationary component and a rotating component rotatablely connected to the stationary component. One of the stationary component and the rotating component is provided with at least one group of clamping grooves each including a plurality of clamping grooves that are consecutively arranged in a rotation direction of the rotating component. The rotating mechanism further includes at least one elastic clamping block, which is in one-to-one correspondence with the at least one group of clamping grooves, disposed on another one of the stationary component and the rotating component. Each elastic clamping block is configured to be capable of being matched with any clamping groove of a plurality of clamping grooves included in a corresponding group of clamping grooves, and to be capable of being elastically deformed in a direction away from the clamping groove under a squeezing action of an inner surface of the clamping groove.

An operating system for an architectural covering is provided. The operating system allows at least three modes of operation of an architectural covering. A transmission may be included between an input assembly and an output drive member, and the transmission may be selectively engaged to place the operating system into one of the at least three modes of operation. The operating system may include a first drive section including an input, a second drive section including an output, and a control mechanism arranged to selectively lock an element of the first and second drive sections to control movement of the output of the operating system upon actuation of the input. A shift lock is also disclosed herein. In use, the shift lock operates to restrict shifting operation of the operating system from one operating mode to another.

An adjusting device for adjusting a light module in a vehicle lighting device. The adjusting device includes an adjusting mechanism into which a rotary motion can be transmitted. The adjusting device also includes a transmission element that can be used to transfer the rotary motion. The adjusting mechanism and the transmission element are connected in a way that transmits torque via a coupling that provides torque overload protection. The adjusting mechanism is embodied with at least two parts and features a first part into which a rotary motion can be transmitted and it features a second part that is embodied as a part of the coupling.

A clutch assembly for a toy includes a clutch disc member and an inserting member. The clutch disc member includes a central opening and a plurality of seats distributed in a circular pattern. The inserting member includes a plurality of wedges distributed in a circular pattern. The seats and the wedges are designed to (A) engage the wedges in the seats when a force exerted between a driving element operably connected to the clutch disc member and a driven element operably connected to the inserting member is less than a predetermined force level, and (B) automatically disengage the wedges from the seats when the force exerted exceeds the predetermined force level, and (C) re-engage again when the excessive force is released so as to fall below the predetermined force level after slippage of the wedges out of the seats.

A driving force transmission mechanism includes a first transmission member and a second transmission member that are arranged on an identical rotational center axis. The first transmission member includes one or more transmission claws engaged with the second transmission member. The transmission claw includes, at a position away from the rotational center axis, a fixing portion with respect to the first transmission member, and extends in a direction crossing a direction directed from the fixing portion to the rotational center axis. The second transmission member includes one or more stoppers engaged with a tip end of the transmission claw and one or more holding portions engaged with a side of the transmission claw, which faces the rotational center axis.

In example embodiments, a discrete torque limiter is described that includes a first cylindrical member including grooves along a longitudinal surface of the first cylindrical member. The discrete torque limiter includes a second cylindrical member arranged concentrically with the first cylindrical member. The second cylindrical member can be adapted to move independently around the first cylindrical member. The second cylindrical member can include flexural spokes with teeth that engage the grooves along the first cylindrical member when no torque is applied and that disengage from the grooves when a torque that exceeds a threshold torque is applied to the first cylindrical member or second cylindrical member.

A torque limiting tool is described. The tool comprises a torque limiting mechanism comprising a sleeve connectable to a drive shaft and a torque drive coupler that resides within a housing. The sleeve comprises a sleeve annular sidewall having a plurality of outwardly projecting elongated first lobes and recessed first grooves that are circumferentially positioned along the length thereof. The drive coupler comprises a socket defined by a coupler annular sidewall having a plurality of outwardly projecting second elongated lobes and recessed second grooves positioned along the coupler interior sidewall. Torque is transferred therebetween when the ramped surfaces of the first and second lobes mate within respective second and first grooves of the coupler and sleeve. When a torque limit is exceeded, the first and second lobes of the sleeve and coupler disengage for their respective second and first grooves.

A sliding clutch for an adjustment device of a rearview device of a motor vehicle comprises two plastic parts. A first part is formed as an external gear wheel having a first multiplicity of first coupling elements and a second part is formed as an internal shaft having a second multiplicity of second coupling elements. The two plastic parts rotate with one another up to a predefined maximum torque namely because a positive fit exists between the first and second coupling elements up to the predefined maximum torque. The invention furthermore relates to a side-view mirror for a motor vehicle having an adjustment device which comprises a sliding clutch according to the invention.
