For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for tightening and loosening fasteners. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

[0019] Referring to FIG. 1, there is shown a cutaway view of the fixed adjustable wrench in a disengagement position. The fixed adjustable wrench 10 provides a head 12 having an adjustable jaw 16 that is selectively fixed into a desired position by a user, upon actuation of a lever 23. The fixed adjustable wrench 10 comprises a handle 11 having a fixed jaw 14 positioned opposite the adjustable jaw 16 and adjacent a shoulder 13. The fixed jaw 14, adjustable jaw 16, and an upper side 15 of the shoulder 13 defining a gap 17 therebetween, wherein the adjustable jaw 16 and the fixed jaw 14 are configured to cooperate to secure an object within the gap 17. The adjustable jaw 16 is in sliding engagement with the upper side 15 of the shoulder 13, such that a distance between the adjustable jaw 16 and the fixed jaw 14 increases as the adjustable jaw 15 slides towards a lateral end of the shoulder 13. In one embodiment, a channel 28 allows for the sliding engagement of the adjustable jaw 15. In the shown embodiment, the faces of each of the fixed jaw 14 and adjustable jaw 16 are smooth. However, in alternative embodiments, the faces may include a grooved, textured, or the like features thereon.

[0020] An engagement member 18 comprises a first end 19 having a first set of teeth 20 configured to selectively interlock with a second set of teeth 21 of the adjustable jaw 16. In the shown embodiment, the first set of teeth 20 and the second set of teeth 21 are in a linear arrangement. However, in alternative embodiments, the sets of teeth 20, 21 may have a curved or an angled arrangement. In one embodiment, the adjustable jaw 16 is slidable between a plurality of positions along the channel 28, wherein each adjacent position adjusts the distance of the gap 17 at intervals.

[0021] In the shown embodiment, the engagement member 18 is disposed within the handle 11, and adapted to selectively engage with the adjustable jaw 16. A second end 22 of the engagement member 18 is operably connected to a lever 23, wherein the lever 23 is configured to selectively move between a disengagement position (FIGS. 1 and 2A) and a disengagement position (FIG. 2B). In one embodiment, the second end 22 is angled to allow for a greater number of teeth 20, 21 to interlock. In the engagement position, the engagement member 18 is coupled to the adjustable jaw 16 via the interlocking of the first set of teeth and the second set of teeth 20, 21. In the disengagement position, the engagement member 18 is disengaged from the adjustable jaw 16 allowing selective positioning of the adjustable jaw 16 along the upper side 15. In this way, the adjustable jaw 16 may be fixed in a desired position by first positioning the adjustable jaw 16 as desired along the upper side 15, actuating the lever 23, and thereby causing the engagement member 18 to move into the engagement position to secure the adjustable jaw 16 in the desired position.

[0022] In the shown embodiment, the lever 23 extends from exterior the handle 11 through an aperture 27. The lever 23 is operably connected to the adjustable jaw 16 via the engagement member 18. In one embodiment, the lever 23 is pivotally connected to the handle at a pivot 25, and further includes a connecting bar 24 that is pivotally connected 26 to a second end 22 of the engagement member 18. The pivot 25 is affixed to the handle 11, such that rotational movement of the lever 23 causes opposing rotational movement about the pivot 25. For example, rotation of the lever 23 away from the handle 23, causes the engagement member 18 to move away from the head 12. Additionally, this actuation of the lever 23 causes disengagement between the sets of teeth 20, 21.

[0023] Referring to FIGS. 2A and 2B, there is shown a cross-sectional view of one embodiment of the fixed adjustable wrench in a disengagement position and in an engagement position, respectively. In the shown embodiments, the fixed adjustable wrench further comprises a ring 50 in sliding engagement with a channel 51. The channel 51 is disposed on an end opposing the adjustable jaw 16, wherein the channel 51 extends along the same longitudinal axis of the handle. In FIG. 2A, the fixed adjustable wrench in the disengagement position, wherein the lever 23 is rotated about the pivot 25 and away from the handle, thereby causing the connecting bar 24 to move away from the adjustable jaw 16. In FIG. 2B, the fixed adjustable wrench in the engagement position, wherein the lever 23 is rotated about the pivot 25 and secured towards the handle via the ring 50, thereby causing the connecting bar 24 to move towards the adjustable jaw 16, and interlock the engagement member 18 with the adjustable jaw 16.

[0024] Referring to FIGS. 3A-3C, there is shown a front view of another embodiment of the fixed adjustable wrench in a disengagement position, a close-up view of the lever and engagement member of FIG. 3A, and a close-up view of the lever and engagement member of FIG. 3A, respectively. In the shown alternative embodiment, the fixed adjustable wrench 10 includes a head 12 having a channel 28 configured to receive the adjustable jaw 16. The channel 28 extends from an upper side 15 through the shoulder 13, whereby the shoulder 13 is offset lateral from the fixed jaw 14.

[0025] In the shown alternative embodiment, the lever 23 is pivotally connected to the shoulder 13 via the lever pin 30. The engagement member 18 is connected to the lever 23 via the connecting bar 24, wherein the connecting bar 24 includes pivots 25, 26 respectively. The engagement member 18 comprises a first set of teeth 20 positioned opposing a second set of teeth 21 of the adjustable jaw 16. Further, the second set of teeth 21 have a length greater than the length of the first set of teeth 20. However, in an alternative embodiment, the first set of teeth 20 have a length greater than the length of the second set of teeth 21. The adjustable jaw 16 further includes a grooved face 29 opposing a grooved face of the fixed jaw 14, defining a gap 17 therebetween.

[0026] Referring to FIG. 4, there is shown a front view of another embodiment of the fixed adjustable wrench with a spring. In the shown embodiment, a spring 52 is disposed within a channel of the head, and affixed to the lever 23 at a first end and removably engaged with the head of the fixed adjustable wrench 10. The spring 52 is biased so as to maintain the fixed adjustable wrench 10 in an engaged position. For example, the lever 23 is affixed to the fixed adjustable wrench 10 via a pivot pin 53, whereby the lever 23 is selectively rotatable about the pivot pin 53. The spring 52 engages with an interior face of the head, such that movement of the second end 22 of the engagement member towards the adjustable jaw 16 causes the teeth of the engagement member and the adjustable jaw 16 to disengage. In one embodiment, the spring 52 includes a pair of coaxial cylinders operably connected, wherein a first cylinder slides within the second cylinder allowing the spring 52 housed therein to compress.

[0027] In the shown embodiment, the fixed adjustable wrench 10 further comprises a ring 50 in sliding engagement with a channel 51. The ring 50 is selectively engageable with the lever 23, wherein the ring 50 can maintain a disengaged position of the engagement member. In this way, a user may selectively position the adjustable jaw 16 by sliding the adjustable jaw 16 through a channel configured to receive the adjustable jaw 16. In an alternative embodiment, the spring 52 is affixed to the head of the fixed adjustable wrench 10 and removably engaged to the lever 23. Thus, the spring 52 is biased so as to maintain the fixed adjustable wrench 10 in a disengaged position.

[0028] Referring to FIG. 5, there is shown a front view of another embodiment of the fixed adjustable wrench with a cheater bar. In the shown embodiment, the fixed adjustable wrench includes a cheater bar 57 that is pivotally affixed via hinge 56 to the handle. A twist lock 55 disposed on the cheater bar 57 is operably connected to the hinge 56, such that actuation of the twist lock 55 in a first direction causes the cheater bar 57 to lock into place, and rotation in a second opposing direction causes the cheater bar 57 to release and allow for pivotal arrangement thereof. Further, the cheater bar 57 may be telescopic having a first elongated section operably connected to a second elongated section, such that actuation of the twist lock 55 allows for altering of a lineal length of the cheater bar 57. In the shown embodiment, a handle section 58 configured for hand gripping is disposed at a distal end of the cheater bar 57. The handle section 58 may be recessed or include a high friction for handling.
