A joint assembly joins first and second components about a common axis. The first component has a first end portion having a radially outwardly facing surface shaped to fit radially inside a second surface of a hollow second end portion of the second component to form an interface between the opposing first and second surfaces. The first and second surfaces have a concavity extending laterally with respect to the axis such that when the first and second surfaces are opposingly arranged the opposing concavities define a cavity at the interface. A retaining member is insertable into the cavity at the interface to prevent axial separation of the first and second components. One of the first and second end portions has a free end protrusion axially spaced from the concavity and the other of the first and second end portions has an axially extending recess arranged to receive the free end.

An assembly (100) to be mounted on a vehicle to support a load receiving body on the vehicle. The vehicle having a forward direction of travel with the load receiving body being tillable. The assembly including a primary frame (110), having a longitudinal axis X, that is to be attached to the vehicle. A secondary frame (120) extending between the primary frame and to be attached to the load receiving body. A hinge (170a,b) pivotally attaches the primary frame to the secondary frame for angular movement about a pivot axis that is transverse to the longitudinal axis so that the secondary frame is movable between a lowered position and a raised position. The lowered position has the secondary frame adjacent to the primary frame and the raised position having the secondary frame raised at an acute angle at the hinge. A first actuator (161) is pivotally attached to a portion on the primary frame and is pivotally attached to the secondary frame and operable to cause angular movement of the secondary frame about the pivot axis. A second actuator (162) is attached to the portion and mounted to primary frame and operable to cause movement of the hinge portion in a direction generally parallel to the longitudinal axis X.

The invention provides a reusable linkage which has a coupling which coupling has one or more male connectors formed from two or more compressible leaves; and/or one or more female connectors wherein each female connector is shaped to receive a male connector; wherein the compressible leaves of the male connector are shaped to resiliently engage the female connector and wherein the leaves of the male connector are compressible such that a male connector can be removed from a female connector.

A collapsible steering column assembly includes: a mounting bracket having a pair of arms and is configured to be fixed to a vehicle body; a supporting housing which is disposed between the pair of arms to be tiltable about the mounting bracket; a steering column which passes through the supporting housing so as to be able to undergo a tilt motion together with the supporting housing; and a locking device which is configured to be in a locking state or an unlocking state to selectively allow a telescopic motion and a tilt motion of the steering column by selectively applying clamping force to the pair of arms. The steering column comprises an outer jacket, an inner jacket which is slidably inserted into the outer jacket and a tolerance ring which is interposed between the outer jacket and the inner jacket, and the tolerance ring is configured so as to make the inner jacket and the outer jacket move together to realize a telescopic motion in the unlocking state of the locking device and so as to allow the inner jacket to move into the outer jacket by impact in the locking state of the locking device. The tolerance ring is configured to move relative to the outer jacket in a longitudinal direction while the inner jacket collapses into the outer jacket.

Connector systems for, for example, polymeric solid foam products and products using such systems are disclosed. The connector systems may comprise a pair of hollow coupling members embedded in adjacent foam bodies, such as sections of a surfboard or paddleboard. When axially aligned, the coupling members may be connected together by a connector member that extends into each coupling member. The coupling members have internal projections. The connector member has bent connector channels along which the projections can travel when the connector member is rotated about its axis and in so doing the foam bodies may be connected together or disconnected.

An assemblable structural column joint connection using fiber-reinforced concrete filled round double steel tubes, including an outer high-strength round steel tube, an inner high-strength round steel tube and a round separation plate. The wedge-shaped teeth are provided at two sides of the outer and inner high-strength steel tubes, and wedge-shaped teeth spaced are uniformly distributed along circumferences of the inner and outer high-strength round steel tubes. The round separation plate includes a round plate provided with a central through-hole, and vertical separation walls are provided with on upper and lower surfaces of the round plate. The vertical separation walls are provided with wedge-shaped sliding grooves matching the wedge-shaped teeth. The inner and outer high-strength round steel tubes are fixedly connected to the round separation plate by matching the wedge-shaped teeth with the wedge-shaped sliding grooves.

The invention relates to a fastening element (10) which can be mounted on the upper side of a positionable formwork wall (54) of a formwork system (52). The fastening element (10) has an angular element with a first leg and a second leg. The first leg can take the form of a mounting part which can be fastened in a reversibly releasable manner to the positionable formwork wall (54). As an alternative to this, the first leg can be arranged directly or indirectly on the mounting part. The free end of the second leg has a connection possibility for a push-pull prop (24) or is connected to a push-pull prop (24). The angular element is preferably designed to be pivotable with respect to the mounting part. With the positionable formwork wall (54) set up, the positionable formwork wall (54) can form, together with the fastening element (10) and the push-pull prop (24), an arch into which a closing formwork wall (66) can be inserted.

A metallic-composite joint fitting is provided. The fitting may comprise a frustoconical internal bearing having a bore, a conical sleeve configured to be disposed about the frustoconical internal bearing, a composite structure configured to couple between the frustoconical internal bearing and the conical sleeve, a metallic end fitting configured to be disposed within the bore and couple to the frustoconical internal bearing, and an external nut configured to couple to the metallic end fitting and the conical sleeve, wherein at least one of the frustoconical internal bearing or the conical sleeve comprises a flanged portion mutually configured to couple the conical sleeve to the frustoconical internal bearing via a locking ring.
