Maneuverable ergonomic trailer stands are disclosed. An example portable trailer stand includes a frame having an upper ledge; an extendible leg coupled to the frame, the upper ledge being vertically movable to selectively engage and disengage an underside of a trailer parked on a driveway based on movement of the extendible leg relative to the frame; a wheel connected to the frame, the wheel to remain at a substantially fixed distance from the upper ledge as the upper ledge is vertically moved.

A wind turbine blade handling apparatus for rotating and lifting a blade. The apparatus includes a root device having a root support member with a concave upper surface and rollers having a longitudinal axis parallel to the longitudinal axis of the blade and configured to rotate the blade; a base, and a scissor-lift mechanism with intersecting struts which converts from a lowered position wherein the struts are disposed in a generally coplanar configuration, to an elevated position wherein the struts are disposed in an angled configuration.

An aspect of the present disclosure is directed to a monorail system configured and arranged for displacing at least one maintenance device configured and arranged for machining substantially vertically extending surfaces. Another aspect is directed to a maintenance system consisting of at least one maintenance device which is displaceable on the monorail system.

A camera mount includes a pivotable assembly of a pair of arms and a pocket into which an end of one of the arms is inserted, in one of a plurality of discrete orientations. The arms are pivotably joined to one another by a fastener and permitted to be aligned at one of a plurality of angles. The camera mount is installed in a track, a rail or another system mounted to a fixture of a materials handling facility or another environment, and a camera module is mounted to another end of one of the arms. A position of the camera module is selected by installing the camera mount into a desired location on the track, the rail or the other system. An orientation of the camera module is selected by selecting the one of the plurality of discrete orientations and aligning the arms at one of the plurality of angles.

A telescopic IV and feeding bag pole is disclosed herein. The miniature telescopic IV or feeding bag support pole is configured for children. The support pole includes a telescopic central post with bag holding arms, and a wheeled base with a plurality of casters. The wheeled base includes an H-shaped base member having two parallel supports which are perpendicular mounted to a central support rod. Each of the two parallel supports include castor wheels to allow a child to easily transport the IV pole. The telescopic central post is then mounted onto the central support rod. Furthermore, the telescopic central post has an opening at a top end which receives the holding arms. The holding arm is telescopically adjusted from the telescopic central post to provide the optimal height for a user.

Provided is a stand for a device that is capable of suppressing interference between a plurality of arms that are rotatably coupled and a device attached to an arm. The stand for a device includes a supporter that includes a first fulcrum; a first arm that is coupled to the supporter so as to be rotatable around the first fulcrum, and that includes a second fulcrum on one end; a second arm that includes a first end and a second end, the first end being coupled to the first arm so as to be rotatable around the second fulcrum; a grip; and a joint that is coupled to the second end of the second arm and the grip, is couplable to a device, and for which an orientation of the device with respect to the second arm is changeable by an operation of the grip.

A kit of parts for use in demountably configuring a variety of structural assemblies. A kit may comprise a plurality of cylindrical structural components configured for engagement with various types of male connector components along the sides or at the ends of the cylindrical structural components, there provided for demountable engagement of a female-end socket component at the end of another cylindrical structural component. The kit may additionally comprise components for one or more of roller carriage assemblies and/or one or more of sliding carriage assemblies configured for rolling or sliding movement along rail assemblies comprising a plurality of cylindrical, square, rectangular, or octagonal track components. The rail assemblies may be supported by bases comprising the cylindrical structural components and other components such as weight components, as well as threaded foot components or threaded caster components on which the rail assemblies can be adjustably levelled.
