摘要： A counterbalanced vertical track assembly which may be configured with three types of pulley support assemblies are herein disclosed. The first type of pulley support assembly has a pair of opposed pulley modules having an elongate structural element interposed the two pulley modules which are attached to end plates at both ends of the elongate structural element. The second type of pulley support assembly has a pair of opposed pulley modules which include male end connectors for demountable engagement of the pulley modules with another module of the system with female ends. The third type of pulley support assembly has a pair of opposed pulley modules wherein the modules' pulley brackets are repositionable to varying angular orientations by alternating screw mount positions selected on mount components at opposite ends of an elongate structural element.

摘要： A bicycle retractable bicycle cross bar adaptor includes a bar having a first tube, a second tube and a control unit. The first tube has a first connection end and the second tube has a second connection end which is movably inserted into the first connection end. The second tube includes multiple holes. The control unit includes an inner part, a switch and a sleeve. A switch is pivotably connected to the inner part and the sleeve is mounted to the inner part and the switch. The sleeve includes a flexible tongue to pivot the switch. The switch includes a rod on one end thereof. When the switch is pivoted, the rod is inserted into one of the holes of the second tube to set the length of the bar. When the rod is removed from the hole, the second tube is moved relative to the first tube.

摘要： Ladders, ladder components and related methods are provided. In some embodiments, adjustable stepladders are provided which include locking mechanisms that enable height adjustment of the ladder through application of a force towards the rails of the ladder. In other embodiments, spreader mechanisms are provided with cross bracing located and configured to provide additional stability to the ladder while also incorporating a handle that enables efficient collapsing of the ladder while reducing the potential of pinching ones hands or fingers. In another embodiment, a device is provided for selective coupling with the ladder that includes a support or safety rail and an adjustable tray. The device may be coupled with the ladder in a number of different positions including a stowed position. In another embodiment, a hinge assembly is provided having a magnetic component configured to be magnetically coupled with and temporarily store an object on the ladder.

摘要： A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

摘要： A motor adapter assembly can couple a motor shaft for a ceiling fan motor to a downrod. The motor adapter assembly can include a base plate, a cradle with arms extending through the base plate, and a threaded bushing secured between the arms of the cradle. Threading a cap to the threaded bushing can be used to pivot the downrod between an upright position and a pivoted position.

摘要： A telescopic system comprising at least two profiled rails which are guided linearly on one another in the longitudinal direction, are movable relative to one another over a distance and each have a longitudinal profile with longitudinal grooves and/or longitudinal ribs wherein at least one sliding element is provided on each profiled rail, via which sliding element the at least two profiled rails bear against one another in a slidable manner, and which sliding element is arranged so as to be fastened in an axially non-displaceable manner, at least with respect to the longitudinal direction, on the longitudinal profile of the associated profiled rail. Such a telescopic system is intended to be simpler in design and able to be mounted more easily. This is achieved in that the sliding element, at least with respect to a sliding plane defined by the longitudinal direction and a first transverse direction perpendicular to the longitudinal direction, is then connected to a clamping element so as to be fixed against displacement on the profiled rail, wherein the clamping element is arranged with a clamping fit on the longitudinal profile of the profiled rail, to be precise in or on a longitudinal groove and/or on a longitudinal rib.

摘要： An improved telescoping stick for testing emergency safety systems is disclosed. The telescoping stick retracts so that the user can easily carry the stick throughout a commercial building without inconveniencing the people in the building, and it extends so that the user can easily reach test or reset buttons on emergency devices, such as emergency lights and exit signs. The end of the improved telescoping stick includes a rotatable tip on a ball-and-socket swivel that allows the tip to be orientated in any direction to reach a button of any configuration.

摘要： A telescopic tube is disclosed. By pressing and rotating a switching button, an abutting section is aligned to a first hole of an outer tube and then elastically pushed by an elastic member, a pin section of the switching button is released from engagement with a fastening hole of the inner tube, and the position of the inner tube in the outer tube can be adjusted individually. After the inner tube is adjusted completely and the switching button is pressed to rotated again, the pin section is inserted into the fastening hole, the engaging section is engaged in the first hole. When the switching button is pressed, the movement of the inner tube makes the switching button release from the first hole and the third hole, and the inner tube, the control assembly and the inner mounting member are retractable in the through hole of the outer tube.

摘要： Provided is a leg retention clip for a leg of a tripod and a tripod assembly that includes the leg retention clip. The leg retention clip can be inserted inside a hollow-out inside of a first leg section with slots/holes which output protruding edges of the leg retention clip. When a second leg section is fitted over the first leg section, the protruding edges of the leg retention clip can stop movement of the second leg section and help lock the second leg section in place with respect to the first leg section. If the leg of the tripod includes more than two leg sections, the leg can be provided with multiple leg retention clips.
