  • Patent number: 9410374
    Abstract: A ladder lift is provided. The ladder lift may include a foldable platform, a frame, a motorized gear mechanism, a gear channel and a toggle switch. The gear channel may extend upwardly from a supporting surface along the length of the frame. The gear channel may house a belt track extending along the length of the gear channel. The foldable platform may be rigidly connected to the motorized gear mechanism. The motorized gear mechanism may selectively engage the belt track for causing the foldable platform to move in a specified direction along the length of the gear channel. The toggle switch may be used to engage and disengage the motorized gear mechanism. The frame may support the gear channel, the foldable platform, the motorized gear mechanism and a user. The user may be accommodated on the foldable platform. Then the user may activate the toggle switch so that the foldable platform moves in a specified direction along the length of the gear channel for a predetermined distance.

  • Patent number: 9366042
    Abstract: A collapsible structure is described that can be erected to provide an elevated working platform having two ends and two sides. Two telescopically collapsible ladder frames (10, 12) are disposed above the level of the platform, one on each end of the platform. Each ladder frame (10, 12) is formed of two stiles (20, 22) having telescopically collapsible sections, rungs each extending between respective sections of the two stiles and latch mechanisms for locking the stile sections in the extended position of the ladder frame. Each of the ladder frames (10, 12) further incorporates a guardrail (30, 32) that lies parallel to the rungs (24) when the ladder frame is collapsed. The guardrail (30, 32) is mounted for rotation about a first stile and releasably secured to the second stile. After release from the second stile of the same ladder frame and rotation about the first stile each guardrail is connectable to the second stile of the other ladder frame to lie parallel to a side of the platform.

  • Patent number: 9321618
    Abstract: An apparatus comprising a pair of telescoping arms pivotally coupled between a base and a platform. Each arm comprises a base portion pivotally coupled to the base to pivot about a base pivot axis, an extension portion slidably coupled to the base portion and pivotally coupled to the platform to pivot about a platform pivot axis, and, a pivot support assembly attached along a side of one arm of the pair facing toward the other arm of the pair. The pivot support assembly is configured to allow longitudinal travel of a pivot anchor with respect to the base portion. The pivot assembly is coupled between the pivot anchors. The drive assembly is connected to controllably move the extension portions inwardly and outwardly with respect to the corresponding base portions, and controllably move the pivot anchors toward and away from the corresponding base pivot axes.

  • Patent number: 8985275
    Abstract: A lift safety system that prevents the lifting of a support platform from a support base until all of the support legs for the support base are supporting a minimum amount of weight to ensure stability of the lift. The support base includes a plurality of legs that extend outwardly with each of the legs having an adjustment member with a pad that engages a ground surface. As the adjustment member is adjusted downwardly with respect to the leg, a first engaging member connected to the adjustment member is elevated upwardly to engage a second engaging member thereby releasing a corresponding finger member attached to the support platform from the support base. Once all of the legs are supporting a minimum amount of weight, all of the finger members are released from the support base thereby allowing elevation of the support platform.

  • Patent number: 8973709
    Abstract: A lift includes a mast and a brake module. The mast is for disposing on a working surface and has at least one track. The brake module is connected to a lift module mounted on the mast and includes at least one friction member and at least one forcing member. The friction member has a pressing portion and an axle oppositely arranged. The pressing portion is substantially shaped to engage the track. The forcing member is rotatably disposed on the axle for pivoting axially between a first position and a second position. At the first position, the pressing portion can be moved along the track and stopped by the lift module. At the second position, the forcing member displaces the friction member to force the pressing portion tightly against the track. Thus, the brake module is held in position relative to the mast.

  • Publication number: 20150008072
    Abstract: A variable height support with a platform and a base supporting the platform and reconfigurable to selectively change a height of a support surface on the platform relative to a subjacent surface. A control assembly is operable to selectively: a) maintain the support surface at a selected height; and b) release the platform to allow the base to be reconfigured to change the height of the support surface. The control assembly has a ratchet subassembly that, with the control assembly in a first state, allows the base to be reconfigured by exerting a continuous upward force upon the platform that causes the platform to elevate and be blocked within a range at a plurality of different vertical locations against downward movement. The control assembly further has an actuator that is repositionable to change the control assembly into a second state wherein the platform can be lowered over the range.
