A bicycle wheel positioning device includes a case and two positioning units. The two positioning units are respectively installed to the case and each include a roller unit and at least one spring. When the two roller units are applied by a force, the two roller units are pushed away from each other. When the force is removed, the roller units move back and toward each other by the at least one spring in each roller unit.

A device for handling a clothes line, the device being mountable to a support, the device comprising: a body; a pulley mounted to the body for mounting the clothes line thereto; an elongated guide mountable substantially vertically to the support, the body being mounted to the guide and movable longitudinally therealong; and an actuating assembly operative for selectively moving the body along the guide and for selectively rotating the pulley to move the clothes line when the clothes line is also mounted to another pulley and looped around the two pulleys under tension.

The invention provides a system for positioning a viewing screen. The system comprises a base body and at least one screen body. The screen body comprises a suspension hook and, on the one hand, is configured to be rigidly connected, at least in one position of the screen body, to the base body and, on the other hand, is configured to fasten a viewing screen thereto. The system further comprises a securing body for releasably securing the rigid connection between the base body and the screen body. The base body comprises a suspension edge. The suspension hook and the suspension edge are configured to suspend the screen body from the suspension edge of the base body via the suspension hook.

An assembly for attachment to a windowpane is disclosed. The assembly includes an adhesive layer attached to the windowpane, a magnetic material attached to the adhesive layer, and a container comprising a magnetically attracted material.

An apparatus includes an upper member, a lower member disposed beneath the upper member, and a spring disposed between the upper member and the lower member. The upper member has a pin extending downward therefrom. The lower member has a seat configured to receive a free end of the pin. The spring surrounds the pin, and has a free length that is less than the length of the pin. In an unloaded state, the free end of the pin contacts the seat and the spring applies a compressive force to prevent relative lateral movement between the upper member and the lower member. When the lower member carries a load in a loaded state, the load applies a tensile force to the spring that forms a gap between the free end of the pin and the seat, which allows relative lateral movement between the upper member and the lower member.

A system can include a display assembly that includes a display, a display side, a back side and a frame, where the back side includes a serial bus socket; and a camera assembly that includes a camera head unit coupled to an end of an arm, where an opposing end of the arm includes a serial bus connector receivable by the serial bus socket of the back side of the display assembly.

A system can include a display assembly that includes a display, a display side, a back side, a frame and a serial bus socket; and a cable clip, removably attachable to the back side of the display assembly, that receives a portion of a cable that includes a serial bus connector receivable by the serial bus socket.

One embodiment provides a method and apparatus for suspending air conditioning duct works from a support structure comprising unistrut type support beams which apparatus includes a plurality of support brackets arranged and configured for being slidably interlockable with the interior of the unistrut beam members. The support brackets can be slid inside the interior of the support beam until adjacent a support beam which support beam can be connected to the support bracket. In like manner additional support brackets can be inserted into the interior of the support beam members to be adjustably located next to their respective support rod. In such manner multiple support rods can be used to support a frame member even where the support rods are not symmetrically located along the length of the support beam as the support bracket can be slid/moved inside the support beam until lining up with its respective support rod. Additionally, the entire support framework can be moved relative to the plurality of support rods by sliding the framework relative to the support brackets. In such manner the location of the supporting frame member can be changed without moving the support rods.
