  • Publication number: 20190322502
    Abstract: The present invention relates to a scissors lift comprising a bottom frame, a top frame and a scissors mechanism arranged between said bottom frame and said top frame to displace said bottom frame and said top frame relative to each other by transfer of an actuation force. The scissors mechanism comprises a central hollow scissors arm delimited between opposite scissors arm surfaces, wherein said central hollow scissors arm has a bottom pivotal connection connecting it to said bottom frame and a top pivotal connection connecting it to said top frame. Further, the mechanism comprises two passive scissors arms being pivotally connected to said bottom frame and pivotally connected to said top frame. Each of said two passive scissors arms are pivotally connected to said central hollow scissors arm on said opposite scissors arm surfaces of said central hollow scissors arm.

  • Publication number: 20180311091
    Abstract: A platform link mechanism may include a base with a first member rotatably coupled to the base. A second member may be coupled to the first member. The second member may be moveable with respect to the first member between a first position and a second position. A lifting link assembly may be rotatably coupled to each of the base and the second member. A platform mount may be coupled to the second member. The platform mount may be rotatable about a platform pivot with respect to the second member. The lifting link assembly may rotate relative to the first member, the second member, and the base as the second member moves relative to the first member. The first member may rotate relative to the base as the lifting link assembly rotates relative to the first member.

  • Patent number: 9504618
    Abstract: Disclosed here is a jack for the change of a position of the seat base in a wheelchair. The jack has, in the lower frame (1), the driving system of the screw jack with a vertical screw (14) is fixed; and the upper end of the screw (14) is pivotally fixed in the main arms (3) of the scissors system. The driving system of the screw (14) of the screw jack is fixed to the base (11) attached slideably to the lower frame (1) in the tracks (8) in such a way that the screw (14) is permanently in a perpendicular position to the lower frame (1) and the upper frame (2) with maximum deviation of ±10°; and the base (11) is driven by the arms (17), with their first ends fixed pivotally in the main arms (3), and the other ends fixed pivotally in the base (11).
