A fastening device for fastening add-on parts on carrier components has a plug-in locking device, for locking to a carrier component, and a releasable rotary locking device, spaced apart axially from the plug-in locking device and intended for locking to an add-on part. The rotary locking device has an axial supporting element and at least one locking wing, spaced apart axially from the supporting element and extending away radially from a shank of the fastening device. The supporting element and the at least one locking wing have axial locking surfaces, located axially opposite one another. The axial locking surface of the supporting element is arranged axially between the locking wing and the plug-in locking device. The rotary locking device also has a rotary locking stop, which delimits the rotating-in and/or rotating-out action.

In some examples, an apparatus can include a base plate, a plurality of support platforms connected to the base plate, where each of the plurality of support platforms include an attachment plate to connect each support platform to the base plate, a spring plate, and a flange, and a cam to interface with the base plate, where the plurality of support platforms are to radially translate with respect to an axis of the base plate when the cam is rotated.

A quick release connector for coupling a removable device with a mounting surface. The mounting surface can include a wheelchair arm, and the removable device can include a user controller. The quick release connector can enable a user to briefly contact a release mechanism, rotate the removable device by a limited amount, and remove the device with a single hand. The quick release connector can robustly couple the removable device with the mounting surface, enabling the mounted removable device to resist dislodging by knocks and bumps.

Provided is a latch member. The latch member, in one aspect, includes an upper portion and a lower portion extending from one or more surfaces and defining a central axis, the lower portion including first and second lower portions circumferentially spaced from one another and axially spaced from the upper portion to form first and second channels, the first and second lower portions having respective first and second leading peaks opposite the first and second channels, the first leading peak axially offset from the second leading peak, wherein the first and second channels are configured to each receive one of two pins of a related hook member and cause the latch member to rotate relative to the hook member, wherein the latch and hook member are configured to alternate between latched and unlatched configurations as the latch member reciprocates substantially along the central axis relative to the hook member.

A male-female quick connect system is described, along with related methods and uses. Example applications include using the strap as an exercise resistance trainer band, a boating mooring connector, a replacement or supplement to freight transport tie-downs, and others. An interchangeable strap connection system is described, having: a male connector; a strap connected to the male connector; a plurality of female sockets spaced from one another and anchored to a substrate, with each female socket structured to permit the male connector to interchangeably quick connect with and quick release from the female socket.

A fastener includes a male member having a head and a threaded portion protruding from the head along a longitudinal axis, and a female member having a body portion and a tubular tightening portion extending from the body portion along the longitudinal axis. The tubular tightening portion includes a thread bore receiving the threaded portion of the male member and a plurality of teeth formed on an outer surface of the tubular tightening portion. Further, the male member includes at least one arm extending form the head along the longitudinal axis, and the at least one arm of the male member includes a projection protruding radially inward from the arm and engaging the teeth of the female member.
