081126000 | Sliding jaw, handle-lever grip | 8 |
20090320650 | ADJUSTABLE WRENCH - An adjustable wrench includes a body with a first jaw fixed to the body, and a second jaw movable relative to the first jaw. A lever mechanism is coupled to the body and the second jaw to effect motion of the second jaw relative to the first jaw. The wrench also includes a locking mechanism having a free state in which the first and second jaws move relative to each other, and a locking state in which the first and second jaws are locked from movement away from each other. The locking mechanism changes from the free state to the locking state after an object is gripped between the first and second jaws. The locking mechanism includes a pawl coupled with the lever mechanism, the pawl being arranged to move linearly into engagement with the body when the locking mechanism changes from the free state to the locking state. | 12-31-2009 |
20130186242 | Fire Sprinkler Head Shut-Off Tool With Fusible Release Mechanism - The disclosed invention relates to a fire sprinkler shut-off tool for stopping water flow from an activated fire sprinkler head. Due to the lack of any automatic safety release mechanisms, such tools currently on market suffer the disadvantage of requiring constant monitoring in case fire rekindles. The shut-off tool comprising a pair of adjustable clamping arms and an actuator assembly for adjusting and fixing the clamping arms addresses the safety issue by integrating a fusible link locking tab into the actuator assembly. The presence of a nearby fire melts and separates the locking tab thereby releasing the clamping arms from an activated fire sprinkler head. The shut-off tool also addresses the safety problem of firemen or building maintenance personnel using a shut-off device that requires two hands while working from a ladder as this device can be easily used with one hand. The shut-off tool also achieves the object of universal fit on most fire sprinkler heads by use of the adjustable angled clamping arms and by locating a sealing surface on each of the clamping arms so as to permit operation with fire sprinklers mounted in an upright position. | 07-25-2013 |
20130247725 | Adjustable Wrench - An adjustable wrench includes a handle including a notch defined therein. A driving head is pivotally fixed to the handle for engaging an object that is driven by the adjustable wrench. The driving head and the handle include first and second springs engaged therebetween. The first and second springs each include a first end abutting against the handle and a second end abutted against the driving head, respectively. The notch receives the first and second springs. Coils of the second spring are disposed within a space delimited by coils of the first spring. One of the first and second springs is coiled clockwise from the first end to the second end thereof, and the other of the first and second springs coiled counterclockwise from the first end to the second end thereof. | 09-26-2013 |
20130319187 | WRENCH - The present invention provides a wrench which includes a movable jaw, a fixed jaw and a slidable member formed at the bottom portion of the movable jaw and slidably mounted to the main body. In the present invention, a toggle member can be driven to rotate through rotating a handle of the wrench, and the toggle member can smoothly move to and fro between a driving space and an evading space of the slidable member. Whereby, the present invention is simple in structure, has characteristics of smoothly engagedly-cooperative movements between parts of the wrench, so that it can make full use of the force applied by the user and has excellent effects of use. | 12-05-2013 |
20130327186 | WRENCH - A wrench is configured to rotate a fastener. The wrench includes a handle and a head pivotally coupled to the handle. The head includes a first jaw configured to engage the fastener and a second jaw configured to engage the fastener. The second jaw is movable with respect to the first jaw to adjust a distance between the first jaw and the second jaw. The wrench also includes an actuator operable to move the second jaw with respect to the first jaw to adjust the distance. The handle is pivotally coupled to the head such that rotation of the handle with respect to the head moves the second jaw toward the first jaw. | 12-12-2013 |
20140069238 | Adjustable wrench - An adjustable wrench includes a fixed jaw base, an adjustable jaw base and a handle. The adjustable jaw base includes a slide rod which is slidably movable in a slide grove of the fixed jaw base to adjust the space to clip an object. A poke rod of the handle is located in a poke recess of the slide rod to provide an action force or a limit force to the slide rod. The slide rod is provided with a spring to react to the action force or limit force of the poke rod. One side of the fixed jaw base has a first operation portion for the user to press and control the space to clip the object, enhancing the convenience to turn a workpiece. Particularly, when the handle is pivoted, the poke rod in the poke recess will direct act on the center of the slide rod. | 03-13-2014 |
20140260827 | SELF-ADJUSTABLE WRENCH - The disclosure is directed to a self-adjusting wrench, comprising a movable jaw member, a fixed jaw member a biasing member and a handle, wherein the movable jaw member, the fixed jaw member and the handle engage to self-adjust and lock the gap between the movable jaw and the fixed jaw upon applying pressure to the jaws using the handle. | 09-18-2014 |
20150143963 | PIPE WRENCH - A pipe wrench includes a body and a first jaw has one end fixed to the body, and a second jaw is slidably located in a first recess defined in the top of the body and is located beneath the first jaw. A resilient member is connected between the body and the second jaw. A first link has one end pivotably connected to an end of the second jaw. A second link has the first end thereof pivotably connected to the mediate portion of the first link. An adjustment member threadedly extends through a closed end of the body and contacts against the second end of the second link. The second jaw is quickly slid by the resilient member and controlled by the adjustment member, so that the object can be released and clamped quickly. | 05-28-2015 |
