WRENCH WITH ENGAGING JAWS
An example wrench is provided. The example wrench includes a first jaw having a first jaw engaging surface configured to engage a first side of a fastener and a second jaw having a second jaw engaging surface configured to engage a second side of a fastener. A first plane defined by the first jaw engaging surface may intersect with a second plane defined by the second jaw engaging surface at an engagement angle. The engagement angle may be an acute angle.
1 . An adjustable wrench comprising:
a handle;
a first jaw fixed relative to the handle, said first jaw having a first jaw engaging surface configured to engage a first side of a fastener;
a second jaw moveable relative to the first jaw, said second jaw having a second jaw engaging surface configured to engage a second side of the fastener; and
an adjustment mechanism operatively coupling the first jaw and the second jaw to permit sliding of the second jaw towards the first jaw;
wherein the first jaw engaging surface is substantially flat and defines a first plane;
wherein the second jaw engaging surface is substantially flat and defines a second plane; and
wherein, when the second jaw is moved towards the first jaw via operation of the adjustment mechanism to where the second jaw contacts the first jaw, the first plane and the second plane are not parallel to each other and define an engagement angle therebetween that is less than five degrees.
2 . The adjustable wrench of claim 1 , wherein the engagement angle is approximately three degrees.
3 . The adjustable wrench of claim 1 , wherein the engagement angle between the first and second planes remains constant as the second jaw is moved towards or away from the first jaw.
4 . The adjustable wrench of claim 1 , wherein the first jaw further comprises an off-corner loading recess disposed adjacent to the first jaw engaging surface between the first jaw engaging surface and the handle.
5 . The adjustable wrench of claim 1 , wherein the first jaw engaging surface comprises a first front edge near an end of the first jaw opposite the handle, the first jaw further comprising:
a first front chamfered surface disposed adjacent to the first front edge of the first jaw engaging surface.
6 . The adjustable wrench of claim 5 , wherein the second jaw engaging surface comprises a second front edge near the end of the second jaw opposite the handle, the second jaw further comprising:
a second front chamfered surface disposed adjacent to the second front edge of the second jaw engaging surface.
7 . The adjustable wrench of claim 1 , further comprising:
a first side chamfered surface disposed adjacent to a side edge of the first jaw engaging surface; and
a second side chamfered surface disposed adjacent to a side edge of the second jaw engaging surface,
wherein the first side chamfered surface and the second side chamfered surface are on the same side of the adjustable wrench.
8 . The adjustable wrench of claim 1 , wherein the adjustment mechanism comprises a wormscrew.
9 . The adjustable wrench of claim 1 , wherein the adjustment mechanism comprises a turnable knurl interfacing with a slotted pin.
10 . The adjustable wrench of claim 1 , wherein the engagement angle is between two degrees and five degrees.
11 . An adjustable wrench configured to have an adjustable opening for engaging fasteners of varying sizes, the adjustable wrench comprising:
a handle opposite the adjustable opening;
a first jaw fixed relative to the handle, said first jaw having a first jaw engaging surface configured to engage a first side of a fastener;
a second jaw moveable relative to the first jaw, said second jaw having a second jaw engaging surface configured to engage a second side of the fastener; and
an adjustment mechanism operatively coupling the first jaw and the second jaw to permit sliding of the second jaw towards the first jaw; and
wherein, when the second jaw is moved towards the first jaw via operation of the adjustment mechanism to where the second jaw contacts the first jaw, the first jaw engaging surface and the second jaw engaging surface are not parallel to each other and intersect at an intersection point such that there is a gap between the first jaw engaging surface and the second jaw engaging surface forward of the intersection point toward the adjustable opening.
12 . The adjustable wrench of claim 11 , wherein the first jaw further comprises an off-corner loading recess disposed adjacent to the first jaw engaging surface between the first jaw engaging surface and the handle such that, when the second jaw is moved towards the first jaw via operation of the adjustment mechanism to where the second jaw contacts the first jaw, there is a second gap between the first jaw and the second jaw rearward of the intersection point toward the handle.
13 . The adjustable wrench of claim 11 , wherein the first jaw engaging surface comprises a first front edge near an end of the first jaw opposite the handle, the first jaw further comprising:
a first front chamfered surface disposed adjacent to the first front edge of the first jaw engaging surface.
14 . The adjustable wrench of claim 13 , wherein the second jaw engaging surface comprises a second front edge near an end of the second jaw opposite the handle, the second jaw further comprising:
a second front chamfered surface disposed adjacent to the second front edge of the second jaw engaging surface.
15 . The adjustable wrench of claim 11 , further comprising:
a first side chamfered surface disposed adjacent to a side edge of the first jaw engaging surface; and
a second side chamfered surface disposed adjacent to a side edge of the second jaw engaging surface,
wherein the first side chamfered surface and the second side chamfered surface are on the same side of the adjustable wrench.
16 . The adjustable wrench of claim 11 , wherein the adjustment mechanism comprises a wormscrew.
17 . The adjustable wrench of claim 11 , wherein the adjustment mechanism comprises a turnable knurl interfacing with a slotted pin.
18 . The adjustable wrench of claim 11 , wherein the first jaw engaging surface defines a first plane;
wherein the second jaw engaging surface defines a second plane; and
wherein, when the second jaw is moved towards the first jaw via operation of the adjustment mechanism to where the second jaw contacts the first jaw, the first plane and the second plane define an engagement angle therebetween that is less than five degrees.
19 . The adjustable wrench of claim 18 , wherein the engagement angle is between two degrees and five degrees.
20 . The adjustable wrench of claim 11 , wherein when the first jaw and the second jaw engage a fastener in the adjustable opening, the first side of the fastener is fully engaged with the first jaw engaging surface, the second side of the fastener is partially engaged with the second jaw engaging surface.
