Embodiment Construction

[0023] The subject matter provides wrenches, particularly Stillson wrenches (commonly referred to as pipe wrenches), which exhibit enhanced resistance to damage to the wrench housing when lateral loads are applied. The increased resistance to damage to the wrench housing is due to one or both of the following features.

[0024] One feature is one or more geometric features that incorporate a channel extending through the wrench housing within which the shank of the upper jaw is disposed. Certain channel geometries can include one or more of: (i) inner walls that diverge away from each other, (ii) inner walls with one or more arcuate or non-linear regions or portions, and / or, (iii) ) openings of different sizes on opposite sides of the wrench housing.

[0025] Another feature is the provision of a specific spacer member that is disposed in the channel of the wrench housing. A spacer is positioned at least partially around the shank of the upper jaw and between the shank and a...

Abstract

The invention describes a wrench comprising: a handle defining a unitary housing; a handle defining a longitudinal axis and having an end defining a first jaw; and a second jaw spaced from the first jaw and secured to the housing. Two jaws; wherein the housing defines: a first face positioned adjacent to the second jaw; a second face spaced apart from the first face; and a channel having a passage through the housing between the first face and the second face a plurality of inner wall surfaces; wherein a lateral force applied to one of the handle and the housing causes a portion of the handle adjacent the first face to displace laterally in the channel and contact a flatter portion of at least one of the inner wall surfaces , causing the shank to apply a load to a relatively small surface area portion of at least one of the inner wall surfaces of the housing immediately adjacent to the first face; wherein at least a portion of at least one of the inner wall surfaces defines effective application of load to the The surface configuration of the larger surface area portion of at least one of the inner wall surfaces between the face and the second face.

Description

[0001] This application is a divisional application, and its original application is a Chinese patent with the application number 201810948983.X, the application date is August 20, 2018, and the invention name is "pipe wrench with a shell with expansion opening or gasket" Apply. technical field [0002] The present subject matter relates to wrenches, in particular Stillson wrenches, having flared or curved openings in the wrench housing. This subject also relates to the use of one or more spacers in a wrench housing, particularly a Stillson wrench. This subject also relates to methods for reducing the likelihood of wrench failure due to excessive lateral loading. Background technique [0003] Stillson wrenches (commonly referred to as "pipe wrenches") or other such wrenches utilize rear jaws (herein lower jaws) fixed to the handle and movable hook jaws (herein lower jaws) that pivot to a limited extent around the handle. called the upper jaw). Typically, the hook jaws can...
