Abstract:
A wedging clamp assembly is provided for retaining a saw blade. A housing defining a vertical cavity therein is included in the assembly. The cavity includes a top end and a bottom end tapered with respect to the top end. Extending through a bottom end of the housing is a saw blade passageway included in the bottom end of the cavity. Disposed inside the cavity is a saw blade retention mechanism. A piston is further disposed within the cavity. The saw blade retention mechanism is configured for lockingly retaining a saw blade upon insertion into the passageway, thus, causing the piston to be biased against the bottom end of the cavity. At least one locking element is further included in the saw blade retention mechanism, and such locking element is disposed in the cavity for engaging the bottom tapered end. A wedging clamping force exerted by the at least one locking element is applied to the saw blade, and such force renders the saw blade immobile relative to the housing. The saw blade retention mechanism is configured to release the blade when the biasing force on the piston is overcome by an opposing force applied to the piston, thus, releasing the wedging clamping force.
Abstract:
An apparatus in an example comprises a seat, a torso support, and a connector. The seat comprises a rigid core. The torso support is coupled with the seat. The connector is coupled with the seat and/or the torso support. The connector is removably connectable with an accessory that serves to at least in part support a weight of a patient relative to a load-bearing surface. A location of the patient on the seat with a front of the patient faced toward the torso support and the connector coupled with the accessory allows control by a caregiver of an upper body of the patient for and during transfer of the patient by the caregiver from a start location to a target location.
Abstract:
A shifting device including first and second shift control members, a takeup element, a holding member, and a release member. The takeup element configured for winding and unwinding a tensioned control cable. The first control member is rotatable about a handlebar and configured to rotate the takeup to at least pull or wind the control cable onto the takeup. The second control member is a return-to-neutral member for rotating the takeup to release the. The holding member is rotatable with the takeup and retains the takeup in select angular positions. The release member is operable for disengaging the holding member in response to the actuation or return stroke of the second control member for allowing the takeup to unwind the cable a sufficient amount to enable a single gear shift.
