Abstract
Various offset adjustable wrenches and methods are disclosed herein. The offset adjustable wrench has first and second jaws. The second jaw can be moved relative to the first jaw to grip objects of various sizes. The second jaw can be connected to a sliding element that can reduce or eliminate wobble of the second jaw to improve grip strength. The first and second jaws can be offset from a handle such that a user can grip and rotate an object with the offset adjustable wrench without injuring the user's hand contacting an adjacent surface, such as a wall or ceiling.
Claims21
An offset adjustable wrench comprising:
- a base comprising a chamber;
- a sliding element received in the chamber, the sliding element comprising a plurality of cylindrical rails;
- a first jaw connected with the base;
- a second jaw comprising a first end and a second end, the first end opposite the first jaw and extending along a longitudinal central plane, the second end connected with the sliding element and offset at a non-zero angle relative to the first end, wherein the longitudinal central plane does not intersect the plurality of cylindrical rails;
- and
- a worm gear configured to operatively engage with the sliding element such that rotation of the worm gear translates the sliding element relative to the base, thereby translating the first jaw relative to the second jaw.
3 more elements
An adjustable wrench comprising:
- a base comprising a cavity;
- a fixed jaw connected to the base;
- a sliding guide configured to be received in the cavity, the sliding guide comprising rails;
- an adjustable jaw comprising a first end and a second end, the first end opposite the fixed jaw and extending along a longitudinal central plane, the second end connected to the sliding guide and offset at a non-zero angle relative to the first end, wherein the longitudinal central plane does not intersect the rails;
- a worm screw configured to engage with the sliding guide such that rotation of the worm screw translates the sliding guide relative to the base, causing the adjustable jaw to be moved relative to the fixed jaw;
- and
- a handle configured to be grasped by a user,
- wherein the fixed jaw and the adjustable jaw are offset from the handle.
5 more elements
An offset adjustable wrench comprising:
- a base comprising a cavity, the cavity comprising three cylindrical slots;
- a guide comprising three cylindrical rails configured to be respectively received in the three cylindrical slots of the cavity, wherein one of the three cylindrical rails comprises teeth;
- a fixed jaw connected with the base;
- an adjustable jaw comprising a first end and a second end, the first end opposite the fixed jaw and extending along a longitudinal central plane, the second end connected with the guide and offset at a non-zero angle relative to the first end, wherein the longitudinal central plane does not intersect the three cylindrical rails;
- a worm gear configured to engage with the teeth of the one of the three cylindrical rails such that rotation of the worm gear translates the guide within the cavity relative to the base to move the adjustable jaw relative to the fixed jaw while maintaining the adjustable jaw opposite the fixed jaw;
- and
- a handle,
- wherein the base extends from the handle at an angle such that the adjustable jaw and fixed jaw are positioned on a plane that is offset from another plane of the handle.
5 more elements
An offset adjustable wrench comprising:
- a fixed jaw unit comprising:
- a base comprising a chamber;
- and
- a first jaw;
- a movable jaw unit comprising:
- a sliding element received in the chamber, the sliding element comprising a plurality of elongate rails, each of the elongate rails having a respective longitudinal axis;
- and
- a second jaw having a free end, wherein a plane that passes through the longitudinal axes of the elongate rails does not pass through the free end;
- and
- a worm gear configured to operatively engage with the sliding element such that rotation of the worm gear translates the movable jaw unit relative to the fixed jaw unit, thereby translating the movable jaw unit relative to the fixed jaw unit.
