Abstract
A tool is provided in order to facilitate utilization by users in a wide variety of applications. By way of example, a multipurpose tool includes a first handle having a first axle and a second handle having a second axle; a first jaw and a second jaw, defining a stowed position and a deployed position, where in the stowed position the first jaw is received within the second handle and the second jaw is received within the first handle; a third jaw and a fourth jaw, defining a stowed position and a deployed position, where in the stowed position the third jaw is received within the second handle and the fourth jaw is received within the first handle, where the first jaw and fourth jaw are pivotably attached at the second axle, the second jaw and third jaw are pivotably attached at the first axle.
Claims15
A multipurpose tool comprising:
- first and second handles configured for relative movement between a closed position and an open position, wherein the first handle comprises a first axle extending thereacross, the second handle comprises a second axle extending thereacross, and wherein the first handle comprises a first cam surface and the second handle comprises a second cam surface;
- first and second jaws rotatably connected to the first and second handles, respectively, wherein the first jaw defines an opening through which the first axle extends, and wherein the second jaw defines an opening through which the second axle extends;
- third and fourth jaws rotatably connected to the second and first handles, respectively, wherein the third jaw defines an elongated opening through which the second axle extends, and wherein the fourth jaw defines an elongated opening through which the first axle extends;
- first and second cam followers attached to the first and second jaws, respectively, wherein the first and second cam followers follow along the second and first cam surfaces, respectively, as the first and second handles move between the closed position and the open position;
- and
- third and fourth cam elements fixedly attached to the third and fourth jaws, respectively, wherein the third and fourth cam elements rotate relative to the second and first cam followers as the third and fourth jaws rotate from a stowed position within the second handle and first handle, respectively, to a deployed position, wherein the third and fourth cam elements bias the third and fourth jaws away from the first and second axles, respectively against a biasing force into engagement with the first and second jaws, respectively, in response to the third and fourth jaws being in the deployed position.
A multipurpose tool comprising:
- a first handle and a second handle configured for relative movement between a closed position and an open position, wherein the first handle rotates about a first axis to the open position and the second handle rotates about a second axis to the open position;
- a first jaw and a second jaw rotatably connected to each other at a third axis, wherein the first jaw is connected to the first handle at the first axis and the second jaw is connected to the second handle at the second axis;
- a third jaw and a fourth jaw, wherein the third jaw is rotatably connected to the second handle at the second axis and the fourth jaw is rotatably connected to the first handle at the first axis;
- a first cam surface attached to the first handle and a second cam surface attached to the second handle;
- a third cam element attached to the third jaw and a fourth cam element attached to the fourth jaw,
- wherein in response to rotation of the third jaw about the second axis from within the second handle, the third cam element presses against the second cam surface and biases rotation of the third jaw off of the second axis to receive the first jaw within a cavity of the third jaw, and
- wherein in response to rotation of the fourth jaw about the first axis from within the first handle, the fourth cam element presses against the first cam surface and biases rotation of the fourth jaw off of the first axis to receive the second jaw within a cavity defined by the fourth jaw.
