摘要： A double-ended wrench is described having an elongated handle formed substantially nontwisted extending in a longitudinal direction, a first wrench head positioned at one end of the wrench and a second wrench head positioned at the other end thereof. Each wrench head has an orifice with an imaginary axis of wrench rotation. The first wrench head is positioned relative to the second wrench head whereas the axis of wrench rotation of the first wrench head is substantially perpendicular to the axis of wrench rotation of the second wrench head. The elongated handle comprises a first handle portion connecting to the first wrench head, and a second handle portion connecting to the second wrench head. Each handle portion has an elongated cross-sectional shape when viewed in a cross-sectional plane perpendicular to the longitudinal direction. Each cross-sectional shape is elongated in a predetermined direction, and, the first handle portion is positioned relative to the second handle portion whereas the cross-sectional shape of the first handle portion is elongated in a direction substantially perpendicular to the direction in which the cross-sectional shape of the second handle portion is elongated.

摘要： An adjustable, open end wrench is described which has a wrench head for turning a variety of different size fasteners. The wrench head comprises two jaws each having an engaging surface for engaging with the fasteners. One jaw is generally fixed and connected to a gripping portion formed as a wrench lever and the other jaw is movable relative to the fixed jaw. The wrench head comprises an adjustable mechanism by which the jaws may be spaced apart including a maximum spacing dimension between the jaws. The wrench head further comprises an imaginary centerline intersecting both of the jaws substantially perpendicular to the engaging surfaces of the jaws as viewed from a side view thereof. And further wherein, each jaw has a width dimension measured at the centerline, and the width dimension of both jaws combined is relative to the maximum spacing dimension between the jaws. The width dimension of both jaws combined is substantially equal to or less than 85% of the maximum spacing dimension between the jaws, and, the width dimension of both jaws combined is substantially equal to or greater than 50% of the maximum spacing dimension between the jaws, so as to enhance the interaction and accessibility of the wrench to the fasteners.

摘要： The present invention involves a wrench for tightening and loosening bolts, nuts and fasteners having n number of equal length outside working surfaces. The wrench has a working wrench head with an orifice which contains at least two pairs of flat inside working surfaces. The pairs of inside working surfaces are arranged about and equidistant from an imaginary central axis through the orifice, and the surfaces of each pair form a surface contact angle a with one another. A handle which, is removably or permanently connected to the working wrench head and adapted for rotation of the working wrench head. In one preferred embodiment, the wrench has at least two pairs of surface contact angles that are directly opposite one another.
