A spacer assembly for spaceably coupling a first and second component with a threaded connection bolt, each one of the first and second component provided with one or more fitting apertures. The spacer assembly includes a support member, a base member, and a spacer member having resilient friction elements configured to provide an interference fit engagement with a predetermined friction force with a threaded connection bolt, during use.

An inner housing defines a pin retaining receptacle elongated in an X-direction with entry ramps extending parallel to the X-direction. The inner housing is slidably coupled to an outer housing and extends into an interior thereof. Centering protrusions of one housing can engage the other housing to initially retain the pin retaining receptacle of the inner housing in a central position within the interior of the outer housing in the Y-direction prior to insertion of the pin into the pin retaining receptacle. The other housing can be movable against the centering protrusion to permit the pin retaining receptacle of the inner housing to move out of the central position in the Y-direction in response to engagement of the pin against the entry ramps during insertion of the pin into the pin retaining receptacle.

A shelf system includes a panel including a first opening; a plug in the first opening, the plug including a wing that extends from a rear of the plug and is angled with respect to a side of the plug, and a second opening; and a shelf including a tongue, the tongue inside the second opening such that the shelf is retained with respect to the panel by the plug.

In some examples, an apparatus can include a base plate to interface with a printing device, where the base plate includes an extension member having a pawl, and a lock ring, where the lock ring includes a blocking key, where the lock ring is to interface with the base plate such that the blocking key prevents rotation of the extension member to lock the base plate to the printing device.

A pipe press-fit connecting apparatus includes a connecting device. The connecting device may be used to connect a connected unit to a pressing power providing unit. The connecting device includes a fastener and a coupling pin. The fastener is installed at one end of the installation hole on an exterior surface of a cylinder block and has a fastening pin configured to be resiliently arranged and at least partially be exposed to the installation hole. The coupling pin is inserted through the installation hole and the insertion hole through another end of the installation hole on the exterior surface of the cylinder block to be resiliently coupled to the fastening pin to couple the connected unit to the pressing power providing unit.

The present application provides a fastening clip, which comprises a fastening pin and a fastening sleeve. The fastening pin can be inserted into the fastening sleeve, the fastening sleeve comprises a base and two pairs of retaining wings, the two pairs of retaining wings respectively extend downward from a lower surface of the base, and outer sides of at least one of the two pairs of retaining wings have raised ribs extending in a circumferential direction. The fastening clip of the present application can firmly fasten at least two plates.

A spin nut is operable to attach to a threaded fastener such as a rod. The spin nut includes a threaded nut having a shoulder for supporting a bracket, and a snap retainer detachably coupled to the threaded nut operable to spin onto any position on the threaded rod. At least one wing is formed on the snap retainer operable to attach to a bracket having a hole and spin to adjust to a position on the threaded rod. The snap retainer is detachably couple the plurality of sectioned threaded nut sections operable to spring open on a side opposite the band to allow the threaded rod to pass through.

A retaining clamp of a quick release fastening device, which is latchable in a component opening and in which a fastening bolt is lockable, comprising the following features: two spring legs arranged opposite to each other in a V-shape, the arrangement of which comprises a tapered open end at which the V-shaped spring legs are not connected to each other, and the arrangement of which comprises a widened end, at which the V-shaped arranged spring legs are connected to each other via a connection web with a central passage opening, and each of the two spring legs arranged in a V-shape comprises a central window with a spring web arranged therein, which is fastened at one side and is at least once angled in its course in the direction of the widened end.

Apparatus, systems and methods for providing one or more accessories on a support surface include a base releasably engageable with the support surface, a housing configured to carry at least a first accessory and be releasably engaged with the base and an elongated carrier rod configured to carry at least a second accessory and be releasably engaged with the base.

Provided is a length-adjustable assembly and method including a connecting element for connecting the assembly to a component so that the connection can be subjected to tensile loads and compressive loads, the connecting element being plugged along the longitudinal axis onto an axial end section with respect to the longitudinal axis of the assembly. The connecting element includes a latching arm elastically bendable outwardly with respect to the longitudinal axis in a mounting configuration of the connecting element for plugging the connecting element onto the end portion, wherein the latching arm includes a latching element, wherein the latching element to positively cooperate with a mating latching element of the end portion, the mating latching element of complementary shape to the latching element, in an operating configuration of the connecting element fitted onto the end portion along the longitudinal axis.
