摘要： An expandable car jack includes a vehicle lifting assembly with an upper lifting member, a lower lifting member mechanically coupled to the upper lifting member, and a lifting mechanism capable of moving the upper lifting member to a plurality of raised height positions. A base is coupled to the vehicle lifting assembly and includes a first base support member, a second base support member, and a base support coupler that is operable to selectively couple the first base support member to the second base support member in at least a first coupling position and a second coupling position. The base support coupler selectively mechanically maintains a parallel alignment and a perpendicular alignment of the first base support member and the second base support member when the base support coupler is in the first coupling position, allows the first base support member and the second base support member to freely move between the parallel alignment and the perpendicular alignment when the base support coupler is in the second coupling position, and remains mechanically coupled to at least the first base support member in the first and second coupling positions so that the first base support member cannot move with respect to the second base support member without a mechanical alteration to the base support coupler prior to moving either the first base support member or the second base support member.

摘要： The invention relates to a jack with supporting parts, which are provided as profiles that have U-shaped cross-sections and lateral profile limbs (15, 17) or which are provided as elements with laterally elevated sheet metal lobes (13). Said supporting parts are pivotally interconnected by joints (5, 6) in such a manner that the lateral profile limbs (15, 17) and/or the elevated sheet metal lobes (13) overlap in the vicinity of the joints (5, 6), and arbors pass through borings in the lateral profile limbs (15, 17) or elevated sheet metal lobes (13). The aim of the invention is to reduce the weight of a jack of the aforementioned type as well as the risk of the profile limb (15, 17) kinking. To this end, the bottom of the U-shaped profile or element which, with the profile limbs (15) or sheet metal lobes (13) thereof, tightly surrounds the other profile or element, is provided with beads (19, 21) or lobes (24), which inwardly project and which are arranged inside, however, near the profile limbs (15, 17) or sheet metal lobes of the other profile or element.
摘要翻译：本发明涉及具有支撑部件的千斤顶，该千斤顶被设置为具有U形横截面和侧向轮廓臂（15,17）的轮廓，或者被提供为具有横向升高的金属薄片（13）的元件。所述支撑部件通过接头（5,6）以这样一种方式可枢转地相互连接，使得横向轮廓臂（15,17）和/或升高的金属薄片（13）在接头（5,6）附近重叠，，并且乔木穿过横向轮廓（15,17）或高架金属片（13）中的钻孔。本发明的目的是减小上述类型的千斤顶的重量以及轮廓（15,17）扭结的风险。为此，U形轮廓或元件的底部，其具有轮廓四肢（15）或其金属片（13）紧紧围绕另一轮廓或元件，设置有胎圈（19,21）或然而，向内突出并且布置在内侧的凸角（24）接近另一轮廓或元件的轮廓臂（15,17）或金属片。

摘要： A scissor jack assembly with double-lead Acme threaded screw. Through use of urethane or similar material as a braking means, the jack assembly is operable with a self locking action over a wider range of loads and especially at lower loads where an Acme loading phenomenon that results in said self locking action has previously been unattainable. Faster and smoother jack operation is made possible by employing a thrust bearing, including a plurality of roller or ball bearings, with the jack assembly. A spacing washer is also provided to retain the threaded shaft within the trunnions of the jack assembly, in order that the ends of each of the trunnions need not be machined or stamped to retain the trunnions within the jack assembly. Utilizing such a spacing washer decreases the costs involved with manufacturing the jack assembly, while increasing the ability to repair the jack assembly.

摘要： A sliding jack post stand for a trailer is capable of movement in either of two directions by application of downward force on a lever by an operator standing on one side of a trailer to be moved. A low friction plate is mounted above and spaced from a ground plate on an intermediate spacer and support plate. A slider having parallel side edges bent to enclose opposed side edges of the low friction and support plates in sliding relation supports the lower end of a trailer jack post. The slider has a fulcrum located opposite a series of nests formed in the base plate. The base plate also has a fulcrum located opposite a series of nests formed in the slider. Movement in a first linear direction is accomplished by a force applied downwardly on the handle of an articulated lever placed against one fulcrum and one of the series of nests. Movement in a second linear direction is accomplished by a force downwardly on the handle of the lever placed against the other fulcrum and one of the other nests thereby minimizing the opportunity for back injury.
摘要翻译：用于拖车的滑动千斤顶支架能够通过站立在待移动的拖车的一侧上的操作者通过向杠杆施加向下的力在两个方向中的任一方向上移动。低摩擦板安装在中间隔板和支撑板上的接地板的上方并与之隔开。具有平行的侧边缘的滑块具有弯曲以包围滑动关系的低摩擦和支撑板的相对的侧边缘，支撑拖车千斤顶柱的下端。滑块具有与形成在基板中的一系列巢相对的支点。基板还具有与滑块中形成的一系列巢相对的支点。在第一线性方向上的运动通过向下施加在铰接杆的手柄上的力来实现，所述手柄位于一个支点和一系列巢中的一个之间。在第二线性方向上的运动通过向下放置在杠杆的手柄上的力来实现，该杠杆放置在另一个支点上，并且其它巢之一由此使背部损伤的机会最小化。

The arm has a load accommodation (4) on its free end and engaging the bottom of the vehicle. The arm can be pivoted to various levels directly or by way of levers and transmissions attached to it and to the upright by a manually controlled mechanism, specifically a threaded shaft (5). A brace (15) is attached to the upright and rests flat against the ground or floor (11) at the end of the base facing away from the vehicle while the jack is in the initial-introduction position. The brace is a tab rigidly attached to the upright (1).

摘要： Landing gear for a vehicle such as a trailer, comprising a leg, a foot at the lower end of the leg adapted for engagement with the ground, a pair of generally channel-shaped members forming a tube which extends up from the foot and telescopically receives the lower end of the leg, an elastomeric member disposed in the tube between the lower end of the leg and the foot, and a bearing plate in the tube interposed between the elastomeric member and the lower end of the leg. The tube is attached to the lower end of the leg to permit limited telescopic movement of the leg and the foot whereby the foot is adapted to move upwardly relative to the leg as the landing gear accepts the weight of the vehicle thereby resiliently to compress the elastomeric member between the foot and the bearing plate. A method of making the foot and tube of the landing gear is also disclosed.

摘要： A jack for lifting unbalanced loads such as automobiles, comprises a base having a raised portion thereon with a recess therein to accommodate the base of a jack column. The recess for the jack column is offset on the base and oriented to place a major portion on the base beneath the jack saddle during operation in order to increase stability. A substantially circular collar is mounted about the jack column at a predetermined distance from the base, said collar being supported by a plurality of spaced flexible legs pivotally mounted to the base at one end and curving upwardly to a removable mounting at the collar to prevent column tilt. The jack also includes a saddle assembly having a movable saddle with a protruding portion to engage an aperture in the load which is oriented to approximate the direction of lift point shift. The saddle is free to move perpendicular to the column against the action of a spiral spring when a load is applied and its rotational motion about the column is resiliently restrained by spring means. Thus, the two elements of lift point shift, magnitude and direction, cause compensating movements in the saddle assembly to increase stability, and thereby improve functional reliability and operational safety.
