摘要： A two-part jack system includes a mechanical jack stand with a ratchet mechanism and a ratchet release, and a power unit that may be selectively aligned with and attached to the jack stand for raising or lowering it. A unitary control mechanism carried by the power unit is adapted to selectively lock the power unit in an aligned position relative to the jack stand, and also to selectively release the ratchet release of the jack stand. A locking mechanism is carried in part by the jack stand and in part by the power unit. The unitary control mechanism has three different operating positions. In one operating position the locking mechanism is kept locked while the ratchet release is left in an unreleased state; in a second operating position the locking mechanism is kept locked while the ratchet release is released; and in the third operating position the locking mechanism is held in an unlocked condition while the ratchet release is left in an unreleased state. The power unit has an operating handle, and a single lever which operates the unitary control mechanism is carried on the power unit operating handle for convenient access and easy control by a human operator.
摘要翻译： 两部分千斤顶系统包括具有棘轮机构和棘轮释放的机械千斤顶支架，以及可选择性地对准并附接到千斤顶支架以用于升高或降低其的动力单元。 由动力单元承载的整体控制机构适于将动力单元相对于千斤顶支架选择性地锁定在对准位置，并且还选择性地释放千斤顶支架的棘轮释放。 锁定机构部分由承载架承载，部分由动力单元承载。 统一控制机制有三种不同的运行状态。 在一个操作位置，锁定机构保持锁定，同时棘轮释放被保持在未释放状态; 在第二操作位置，锁定机构在释放棘轮释放时保持锁定; 并且在第三操作位置，锁定机构保持在解锁状态，同时棘轮释放保持在未释放状态。 电源单元具有操作手柄，操作单元控制机构的单个操作杆承载在动力单元操作手柄上，方便操作，操作人员易于控制。

摘要： A floor jack includes a frame having a handle with a control knob, and a pair of pivotal lift arms elevated by pushing the rearward ends by a push bar of a hydraulic cylinder. The cylinder has a control valve attached to a control shaft extending from the control knob. A pair of guide rail are attached to the bottom of the frame; and a pair of rack bars are slidably mounted on each guide rail, and has a forward end pivotally attached to the push bar. A pair of dogs are positioned above the rack bar, each having a rearward end pivotally attached to the frame and a forward for engaging a tooth of the rack bar. The forward end of the dogs engage the rack bar as the lift arms are elevated; and in the event of a hydraulic failure, the dogs lock the lift arms in the elevated position. A release includes a cam tube having a V slotted opening in the underside thereof. A swing plate has a cam follower stud slidably engaged within the V slotted opening. The swing plate includes linkage that is actuated by rotation of the control knob. An initial rotation of the control knob automatically rotates the cam tube to release the dogs, and further rotation opens the valve to lower the lift arms.

摘要： A power unit (or a hydraulic floor jack) includes a rectangular frame with side flanges and has a tubular handle enclosing a control shaft and a control knob. A pivotal lifting mechanism is mounted on the frame including a pair of parallel lift arms having rearward ends interconnected by a lateral push bar. The forward ends (with the bridge) are rotatable upward for lifting a load as the push bar is translated forward within a pair of U channels tracks attached to the inner side flanges. A hydraulic cylinder has a ram for pushing the lateral push bar forward along the tracks for raising the forward ends of the lift arms, and has a releasable control valve for retracting the ram to lower the forward ends of the lift arms. The safety mechanism includes a toothed rack bar secured in the vertical wall of the racks. The lateral push bar has bore holes in the ends thereof. A cylindrical dog is slidably supported within each of the bore holes ad has a proximal end that is extendable for engaging a tooth of the rack bar. The dogs are biased into the extended position, and include release cables and linkage for releasing the dogs from the rack bar by rotating the control knob counter-clockwise.

摘要： A power unit has a frame with a bottom and a pair of lift arms with a cover plate, and a bridge. A lower latch member has a forward end, a middle portion and a rearward end with the middle portion pivotally connected near the lower inner side of one of the lift arms. The rearward end is angled downward, extending below the lower side of the lift arm. The rearward end is biased downwardly and is engagable with the bottom of the frame. The forward end has an upward finger with a beveled-up nose thereon that is engagable with a downward lateral flange at the forward end of the bridge. The bridge is retained by the forward end of the lower latch member, and whereby when the lift arm is lowered to the lowermost position, the forward end is automatically released. An upper latch member has a forward end, a middle portion and a rearward end, with the middle portion pivotally connected to a pivot arm extending downwardly from the cover plate. The forward end has a downward finger with a beveled-down nose thereon, that is biased downwardly and is engagable with an upward lateral flange at the rearward end of the bridge. The rearward end has a button extending upwardly through an aperture in the upper cover plate to release the upper latch member.

摘要： A two-position lift bridge is used with a jack-stand power unit including a forward end, a rearward end, a pair of upward side flanges, with the rearward end having a hydraulic cylinder. A rear cover plate extends horizontally from the side flanges and over the cylinder, and has vertical apertures for positioning the lift bridge, and has a threaded vertical aperture for securing the lift bridge. The frame has a pair of parallel lift arms having forward end that are extendable by the cylinder. Each forward end has a leveling pad pivotally attached having an outwardly extended flange, and one having a vertical aperture and a threaded aperture. The lift bridge includes a rectangular plate one side having downward extending corner flanges with horizontal openings for engaging one of the outwardly extended flanges of the leveling pad. The other side of the plate has a pin extending downward for engaging the aperture in the other leveling pad, and includes a vertical aperture that is aligned with the threaded aperture of the leveling pad for receiving a fastener. The lift bridge can be stored on the cover plate and secured with the fastener. The lift bridge can be positioned on the forward ends of the lift arm by placing the corner flanges on the outward flange of one leveling pad, then positioning the downward pin into the aperture in the other leveling pad, and secured with the fastener.

摘要： A jack stand is for use with a power unit. The power unit includes a rectangular frame and a pair of parallel lift arms having forward ends extendable vertically over the frame. The forward ends of each lift arm have a frusta-conical disc pivotally attached to the inner sides thereof, so that the upper surface of the disc inclines upwardly at an acute angle. The jack stand includes a base plate with a first tubular frame attached thereto and extending vertically therefrom. An upper tubular frame is positioned in telescoping relationship relative to the first tubular frame and has a rectangular lifting plate attached to the upper end thereof. The lifting plate has parallel sides with flanges extending downwardly, with the lower ends of the flanges having an acute angle for engaging the upper surface of the frusta-conical discs of the power unit. The angle of the upper surface of the frusta-conical disc extends upwardly and the acute angle of the lower ends of the side flanges of the lift plate extends downwardly, each at an angle ranging from about 15° to about 30°, and are preferably both inclined at an angle of about 20°.

摘要： A three stage jack stand has a base plate, and includes a first stage tubular rectangular housing. A second stage “U” shaped ratchet shaft has ratchet teeth on the forward edges, and is telescopically positioned in the housing. An upper base is attached to the ratchet shaft having a lower portion also extendable and retractable within the housing; and having a vertical cylindrical opening. A third stage tubular shaft has ratchet teeth in the left and right sides, and is telescopically positioned within the opening in the upper base, and has a lift collar mounted on the upper end. The tubular shaft is automatically controlled by a pair of pivotal upper dogs. The dogs have upper ends biased into a tooth of the tubular shaft, and have inclined lower ends that pivot the upper ends into disengagement when the lower ends are within the tubular housing. The second-stage ratchet shaft is controlled by a pair of pivotal lower pawls aligned with the teeth on the edges of the ratchet shaft, and is actuated by a spring handle.
