A coupling has: a first coupler rotatable about an axis and defining first connections distributed about the axis; a second coupler defining second connections distributed about the axis, the second connections offset from the first connections; and segments distributed about the axis and extending radially from the first connections to the second connections, a segment of the segments having a first end engaging a first connection of the first connections and a second end engaging a second connection of the second connections, the first end circumferentially offset from the second end, a face of the segment abutting against a face of the first coupler when the segment is inserted into the first connection in a first orientation such that a penetration depth of the segment into the first connection in the first orientation is less than the penetration depth in a second orientation opposite the first orientation.

A support system is disclosed that includes a holding structure, a clamp assembly, and a device coupled to the frame of the clamp assembly. The holding structure includes a top portion, a base portion and an intermediate rod portion. The clamp assembly clamps to the intermediate rod portion of the holding structure. The clamp assembly includes a frame, a latch, one or more gear plates, one or more handles, and one or more bias members.

A clamp apparatus is disclosed that includes a body, first and second actuators, first, second, third and fourth gear sets, first and second movable grippers, and at least one leaf spring. The first gear set is coupled to the first actuator and the second gear set is coupled to the second actuator. The first gear set engages the second gear set. The first and second movable grippers are each operatively coupled to the body. The third gear set is coupled to the first movable gripper and the fourth gear set is coupled to the second movable gripper. The third gear set operatively engages the fourth gear set. The leaf spring engages with the third gear set and the fourth gear set to urge the first movable gripper and the second movable gripper toward a clamped position.

The present disclosure provides an assembly including at least one adjustable coupling mechanism. In one aspect, the first coupling mechanism includes a first component having a central axis parallel to its outside surface. The first component further includes an inside surface defined by a bore formed in the first component along a central bore axis. The central bore axis is offset from the central axis. The first component can be coupled to the assembly, uncoupled, rotated about its central axis, and recoupled to change a distance between the first coupling mechanism and another part of the assembly. The first component further includes a plurality of holes formed circumferentially around the bore bottom and extending through the bore bottom and the bottom surface of the first component that can be used to removably couple the first component to the assembly.

Systems, methods, and devices are disclosed for securing structures. One fastener includes a threaded body and a head. The head includes a rounded axial protrusion having a first radial diameter, and a noncircular radial portion for securing the fastener. The noncircular radial portion has a second radial diameter greater than the first radial diameter. The noncircular radial portion is positioned between the threaded body and the rounded axial protrusion.

A pipe connection comprises a connecting piece, a pipe and a clamping ring. The pipe and the clamping ring are made of a material having memory properties. An end of the pipe and the clamping ring have been reversibly expanded co-jointly and firmly and sealingly shrunk to the connecting piece by back shrinkage. Preferably the clamping ring is made from a cross-linked polyolefin by injection molding.

A refill head (100), and oral care implement incorporating the same, wherein the refill head (100) can be uncoupled from a stem (220) of a handle (200) by withdrawing the refill head (100) from the stem of a handle (200) along the longitudinal axis of the oral care implement, which results in locking members (134) on the refill head (100) disengaging from an engagement rib (230) on the stem (220). The locking members (134) and engagement rib (230) may be aligned with or angled relative to the longitudinal axis of the oral care implement. A portion of the stem may be visible through a portion of the refill head to reinforce the proper connection between the refill head and the handle.

A locator (150) for positioning a male element (144) relative to a female element (142) in a joint (132), the male element (144) having a smaller footprint than the female element (142) and the locator (150) comprising an aperture (156) for receiving the male element (144), the aperture (156) having a smaller footprint than the female element (142) and locating means (164) for positioning the locator (150) relative to the female element (142) of the joint (132) such that the aperture (156) of the locator (150) selectively exposes only a part of the female element (142) to ensure location of the male element (144) within the female element (142) in a desired position. The locator (150) further comprises attachment means for attaching the locator (150) to the joint (132), wherein the attachment means is configured to detach on application of a threshold force. The invention therefore provides a simple means of reliably positioning a male element (144) in a desired position relative to a female element (142) in a joint during an initial installation stage without the need to visualise the joint (132). The invention is particularly applicable to a joint (132) in a vehicle suspension system between a frame (132) and a bolt (145) that supports a control arm (16).

When a battery pack is mounted to a battery attachment part, the battery pack is slid in a horizontal direction (a direction substantially perpendicular to an upper-lower direction) with respect to the housing, e.g., along a long longitudinal direction of a battery-side rail part, such that tool-side rail parts of the battery attachment part are introduced into engaging recess portions of the battery pack. Thereby, the elastic members are fitted and compressed in the battery-side rail parts and the tool-side rail parts, so that the elastic members press upwards the battery-side rail part (e.g., the battery pack) and press downwards the tool-side rail parts (e.g., the housing). That is, the elastic members press the battery pack and the housing such that they come close to each other.

A center body attachment system may comprise an engine flange, a center body mounting assembly, and a center body. The center body mounting assembly may retain the center body and the engine flange in slidable engagement, whereby the engine flange and the center body may expand and contract at different rates. The center body may comprise a housing. The housing may comprise a floating counter bore, a spring supporting the floating counter bore, and a slider radially inward of the floating counter bore and retained within the housing by a nut.
