Abstract
A tool, such as an adjustable wrench, has an adjustment mechanism to allow the operator to alter the angle of the tool head with respect to at least a portion of the tool handle. The adjustment mechanism, in a preferred embodiment, utilizes a pair of wings, one or both of which may be pushed rearwardly along the handle to disengage the locking mechanism from the tool head to allow for an operator to alter the angle of the tool head with respect to the handle. In a preferred embodiment, the locking mechanism has at least two teeth which engage a toothed hub which faces rearwardly of a pivot point on the tool head and is held into position by a spring when not disengaged by an operator.
Claims19
A tool comprising:
- a handle portion having a yoke at a forward end;
- a tool head coupled to said yoke at a pivot, said tool head having first and second planar outer surface portions and a toothed hub with a plurality of recessed surfaces and at least a portion of said toothed hub faces rearwardly of said pivot into said yoke, said first and second planar outer surface portions coinciding with a first and a second plane, said first and second planes intersecting at a plane intersection angle, and said toothed hub located between the first and second planes and within the plane intersection angle;
- a locking mechanism having at least two teeth, said locking mechanism carried at least partially within said yoke opposite the toothed hub, and whereby said locking mechanism may be positioned to a first position in which said at least two teeth engage at least two recessed surfaces of the toothed hub and a second position in which said locking mechanism is linearly displaced in a direction away from said toothed hub to allow rotation of said tool head about the pivot.
A flex handle tool comprising:
- a handle portion having a yoke at a forward end;
- a tool head for rotational operation in a plane coupled to said yoke at a pivot for movement of the handle portion orthogonal to the operational plane, said tool head having an adjustable wrench device with first and second planar outer surface portions and a toothed hub with a plurality of recessed surfaces facing rearwardly of said pivot into said yoke, said first and second planar outer surface portions coinciding with a first and a second plane, said first and second planes intersecting at a plane intersection angle, and said toothed hub located between the first and second planes and within the plane intersection angle;
- a locking mechanism having at least two wings, said locking mechanism carried at least partially within said yoke opposite the toothed hub, said wings located respectively on opposing sides of said locking mechanism, and
- whereby said locking mechanism may be positioned to a first position in which said at least two wings are located a first distance from the forward end of the handle and to a second position in which said at least two wings are a second distance from said forward end, said second distance being greater than said first distance to allow pivoting of said tool head.
A flex handle adjustable wrench comprising:
- a handle portion having a yoke at a forward end;
- a tool head for rotational operation in a plane coupled to said yoke at a pivot for movement of the handle portion orthogonal to the operational plane, said tool head having first and second planar outer surface portions and at least a portion of a toothed hub facing rearwardly of said pivot into said yoke and an adjustable wrench device facing substantially forward of said pivot, said wrench device having a first and a second planar outer surface area, said first and said second outer surface areas coinciding with a first and a second plane, said first and second planes intersecting at a plane intersection angle, said toothed hub located between said first and second plane and within the plane intersection angle;
- and a locking mechanism.
