Abstract:
A lightweight jack of the Y-type for raising an edge of a vehicle off the ground, the jack having a folded position and an unfolded position, the jack comprising:a central body (1) including a base (8) to support the jack on the ground;an arm (2), rotatably coupled to the central body, including on a free upper end thereof a gripper (7) matable with the edge of the vehicle;a threaded spindle (3) linked to a bar (5) and a nut (4), the bar being connected to the arm via a bar cross shaft and the nut (4) being connected to the central body (1);a crank winding handle (6) connected to the spindle (3) to rotate the spindle in order to raise or lower the free upper end of the arm (2) and the gripper;the arm (2) comprising an arm cross shaft (9) disposed through transverse holes (10) of the gripper, whereby the gripper is rotatable about the arm;the transverse holes (10) of said gripper (7) being through two holed fins (11) projecting from both sides of a central lengthwise section (14) of the gripper, the two holed fins being folded opposite each other and aligned to take therethrough the supporting arm cross shaft disposed between opposing walls of the arm (1);the holed fins being located crosswise on the gripper not far from an outermost end thereof, folded on a horizontal plane over the arm cross shaft and being disposed completely below the surface of the gripper on which the vehicle rests;a projection of the central lengthwise section (14) comprising at least one gripper fin (29), located on the gripper on a plane, said plane lying outside the plane of the holed fins (11), parallel to a disposition of the transverse holes (10) in said fins (11), and on a longitudinal axis of the gripper; whereby extra support is provided for said gripper (7) on the edge of support flanges of the central body (1) when the jack is in the folded position;an internal reinforcement device (20) disposed inside the free upper end of the arm (2) between the arm cross shaft (9) of the gripper and the bar (5) secured crosswise between arm flanges of the arm;the bar (5), through which the spindle (3) passes, including a U-shaped cross section and a cylindrical neck (25) from a base and towards the exterior, of sufficient length to accept the spindle therethrough;the central body comprising an outermost gap (16) adjacent a connection to the nut (4), the central body comprising, on an outside of the outermost gap, two central-body flanges (17) parallel to each; said central-body flanges including a cross section with L-shapes oriented in opposing directions with respect to a longitudinal axis of the central body; exteriors the two central-body flanges defining a portion of a surface of the central body;a support base (8) including a U-section and a bottom comprising a vertical cross wall (18) of a certain height, the support base being interrupted at lengthwise ends thereof at a certain distance from U-flanges of the U-section, thereby creating two spaces (19) which accept a thickness of the central body (2) of the jack, and wherein the vertical wall is disposed on a lateral plane with respect to a vertical plane containing attachment holes (27) to which the central body is attached.
