A securing device for temporarily limiting movement of a universal joint of a steering column may include a locking element that extends in a longitudinal direction and has a free front end at a front as seen in the longitudinal direction. A handling means may be fitted at a rear of the locking element as seen in the longitudinal direction. The locking element may have a blocking body, and first and second positioning elements that are disposed on opposite sides of the blocking body and extend in the longitudinal direction adjacent to the blocking body. The positioning elements may be resilient relative to the blocking body in a transverse direction that is transverse to the longitudinal direction. The positioning elements help simplify installation and improve protection against damage.

This disclosure provides a system and method for limiting a swing angle of a jib crane, the jib crane having a jib rotatably mounted to a mast. The device can have a collar having a collar height and a collar width, the collar being configured to be fit to the mast at a stop height. The device can also have one or more stopping tabs enagagable with the collar and configured to be positioned on the collar at one or more points about a circumference of the mast. The stop height can place the one or more stopping tabs in a position coincident with the jib to interfere with the swing angle of the jib. The method can use the device to limit the angle through which the jibe crane can swing unimpeded.

A dynamic platform with extending struts has fastened thereto a bi-directional torsional power unit to selectively deliver force opposing either extension or flexion, and to provide assistance in a respective opposite direction. The power unit is threadably mounted on a hinge pin (spline) centrally located on the platform, and is latched to a catch assembly radially located thereto, the hinge pin of the platform communicating with one end of a torsion spring of the power unit and the catch assembly communicating with another end of the torsion spring, to selectively deliver the extension/flexion force. The power unit can be detached, with simple manual operation of the catch assembly, without tools, flipped over and reattached to the same platform attachment points to switch (reverse) extension torque to flexion torque and vice versa.

An adjustable non-view obscuring umbrella having a canopy and a support structure. The support structure having a support post, a plurality of non-articulating umbrella ribs, and at least one articulating umbrella rib. An articulating umbrella rib having an upper rib member, a lower rib member, and an umbrella rib articulation mechanism. An umbrella rib articulation mechanism having an upper bracket and a rotation actuation member, wherein the rotation actuation member is rotationally coupled to the upper bracket

A ball-and-socket joint as an engagement point for a driving element, having a ball head and a socket with a bearing opening, wherein the ball head has a pin for limiting the pivoting of the ball head in the bearing opening, wherein the ball head together with the pin is at least partially arranged in the bearing opening, and wherein at least one damping element is arranged in the bearing opening in such a manner that contact of the pin with the socket is prevented during the pivoting of the ball head.

An article of outdoor foldable furniture with a lamplight decoration structure includes a frame body and a foldable component for connecting the frame body. The frame body is provided with at least one light bar groove. The foldable component includes a first connecting part, a folding part, and a second connecting part. The first and second connecting parts are closed and extended through the folding part. The first connecting part and/or the second connecting part are provided with a luminous body mounting groove. The luminous body mounting groove is correspondingly disposed in the light bar groove of the frame body. A lampshade, provided with a light guide bar, is mounted in the light bar groove of the frame body. A light-emitting unit corresponding to the light guide bar is mounted in the luminous body mounting groove. A controller is conductively connected to the light-emitting unit through flexible wires.

A foldable locking mechanism (300,500) adapted for a frame body (400) includes a first mounting seat (1), a second mounting seat (2), a third mounting seat (4), a first locking component (3) and a driving component (1a,2a). The second mounting seat (2) is pivotally connected to the first mounting seat (1) and the third mounting seat (4). The first locking component (3) is at least partially disposed between the second mounting seat (2) and the third mounting seat (4) and movable between a first releasing position and a first locking position for allowing or restraining a relative pivotal movement of the second mounting seat (2) and the third mounting seat (4). The driving component (1a,2a) is disposed on the first mounting seat (1) and abuts against the first locking component (3). The driving component (1a,2a) is configured to drive the first locking component (3) to move to the first releasing position to allow a folding operation of the foldable locking mechanism (300,500) for allowing a folding operation of the frame body (400).
