  • Publication number: 20120027559
    Abstract: The present document describes a user-operated tool and a method for lifting and dragging a heavy load on a surface. The tool comprises an elongated body having an upper end comprising a grip, a lower end for making contact with the surface in the vicinity of the heavy load, and a flex point located between the upper end and the lower end. The tool comprising a lift and drag member, having a hook member for hooking to the heavy load, connected to the elongated body and is movable about the flex point. The tool comprising a strap reel fixed on the elongated body for winding the strap thereon. In use, the user grips the tool and rotates the elongated member about the lower end and away from the heavy load. The lift and drag member thereby first lifts and then drags the heavy load toward the lower end.

  • Patent number: 7950615
    Abstract: A press-fit extendable support rod includes an outer pipe and an inner pipe sheatheable along the outer pipe. An end of a rope is fixed to the inner pipe, and another end of the rope is extendable outward. A press-fit buckle device is sheathed to a joint of the inner and outer pipes. A rotary arm is pivotally coupled to the press-fit buckle device, and an end of the rotary arm has a first operating portion, a second operating portion and a third operating portion. The rotary arm can be pivotally coupled to the press-fit buckle device by one of the operating portions, and another end of the rope is wound onto each operating portion. When the rotary arm is turned, the rope is pulled, turned around, and pressed at each operating portion, and the length of the inner pipe extended out of the outer pipe is adjusted and fixed.

  • Patent number: 6409151
    Abstract: A mechanical jack for lifting an object including a lever, a base and a fulcrum disposed between the lever and the base and a post for supporting the object being lifted with the post pivotally attached to the lever and a rod movably disposed between the post and the lever and the post cooperating with the lever, the base and the fulcrum is disclosed. The mechanical jack lifts and supports a wide variety of objects including, but not limited to, a snow plow blade, a sofa, a desk, a small building, a boat, a snowmobile, an aircraft, a filing cabinet, a stove, a table and other such loads. An additional feature of the mechanical jack includes a cup member disposed near a second end of the lever which faciliates lifting objects which are inconvenient or difficult to lift. Another feature of the mechanical jack includes a clasp disposed near the first end of the lever for use for assisting in the attachment of an object such as a snow plow blade to a “V” plate mounted on a vehicle.

  • Patent number: 5505433
    Abstract: An apparatus for removing a sheet of material anchored to the floor, such as a carpet, includes an anchor member capable of being releasably anchored to the sheet of material at one location. The anchor member has a foot strap. A handle is pivotally coupled to the anchor member. A rigid connecting member pivotably coupled to the handle by a connecting joint couples a gripper to the handle. The gripper grips the sheet of material at another location. The handle is capable of pivoting about the anchor member in order to pull the sheet of material gripped by the gripper upwardly from the floor.

  • Patent number: 5489083
    Abstract: Provided is a multi-functional tool that includes two elongated bars. When the tool is in a push configuration, the bars are pivotally connected by a collar mechanism to define an obtuse angle between the bars, with each bar having a foot end extending from the obtuse angle. A force properly applied to the pivot point, for example, increases the magnitude of the obtuse angle thereby forcing the foot ends away from each other, whereby mechanical objects engaged by the foot ends are moved away from each other. When the tool is in a pull configuration, the two elongated bars are connected by the collar mechanism such that they are generally parallel and such that the foot ends thereof extend from the collar in the same general direction, with one foot end extending further from the collar than the other foot end.

  • Patent number: 5370365
    Abstract: An erecting tool for converting an articulated flat plate from a folded storage condition to a flat deployed condition, includes an elongated main lever, an extension arm, a hook member and an auxiliary lever. The main lever is adapted to be placed at and pivoted about a stationary location on a dock toward and away from the articulated flat plate. The extension arm is rigidly attached to and extends outwardly in a cantilevered transverse relationship from a lower portion of the main lever. The hook member has an upper end pivotally coupled to the outer end of the extension arm such that the hook member extends below the extension arm. The hook member also has an outer end shaped to hook under an outer edge of the articulated flat plate and to begin lifting the plate upon pivoting the main lever in a rearward direction. The auxiliary lever is pivotally attached to the extension arm adjacent to and inwardly from the hook member.

  • Patent number: 5135200
    Abstract: A snowmobile jack is described herein that raises the rear of the snowmobile off of the ground when it is not in use. Manufacturers suggest that snowmobiles be raised when not in use, so that their tracks do not freeze to the ground. Manufacturers also recommend that snowmobiles be warmed up with their tracks elevated. This cuts down on general wear and tear of the tracks and supporting belts. The jack comprises a vertical lift bar slidable within a sleeve. The bar is raised by a foot pedal lever which acts on the lower end of the bar and is latched in the raised position. The bar carries a transverse rod adjustable in height relative thereto with hooks for engaging the rear bumper of the snowmobile.

  • Patent number: 4768408
    Abstract: A levered tool for spreading apart two interconnected semi-circular concentric brake drum shoes, to facilitate removal of the adjuster member which adjusts the minimum radius of the brake shoes. The semi-circular brake shoes are conventionally closed one toward the other at their inner ends as well as at their outer ends by coil springs, and are relatively pivotable about their inner ends. The adjuster member is usually an elongated spacer member, of adjustable length, extending in between the spaced inner ends of the brake shoes, against the bias of the corresponding coil springs. The outer circumferential faces of the brake shoes each comprises a transverse blade, the innermost edge of which projects inwardly relative to the main body of the brake shoes.

  • Patent number: 4738462
    Abstract: A tool for adjusting the position of a fifth wheel upon a tractor trailer assembly, in which a leverage arm is provided in combination with a pivotally mounted push and pull bar. The leverage arm is pivotally secured to a first mounting platform and extends the distance between the first mounting platform and a second mounting platform. Upon action of the leverage arm from outside of the second mounting platform, the leverage arm exerts a radial force against a pivotally connected push and pull bar. The push and pull bar is attached to the fifth wheel in such a manner as to translate the radial action of the leverage arm into a direct forward or backward action of the fifth wheel.
