Abstract
An apparatus for securing a workpiece comprising first and second clamp members, a transportable elongate member to which the clamp members are mounted for being shifted between clamped and unclamped positions to allow a clamped workpiece to be transported, and a base having a base securing mechanism for securing the base to a work surface and an elongate member securing mechanism which allows the transportable elongate member to be connected in a fixed position relative to the base to keep the secured workpiece fixed relative to the work surface. With this configuration, the elongate member and clamp members may be used in conjunction with the base and/or removed from the base and used remotely thereto.
Claims33
An apparatus for securing a workpiece, the apparatus comprising:
- a bar clamp having a first clamp member, a second clamp member, and a bar, wherein the clamp members are disposed about the bar and wherein the bar clamp can be configured to operate in at least one of a clamp mode and a spreader mode;
- and
- a base having a mating structure for mating with the bar of the bar clamp wherein one of the bar clamp and the base are removable from the other of said bar clamp and said base and wherein the bar clamp remains operable when removed from said base.
An apparatus for securing a workpiece, the apparatus comprising:
- a bar clamp having a first clamp member, a second clamp member, and a bar, wherein the clamp members are disposed about the bar and wherein the bar clamp can be configured to operate in at least one of a clamp mode and a spreader mode;
- a base having a mating structure for mating with the bar clamp wherein one of the bar clamp and the base are removable from the other of said bar clamp and said base and wherein the bar clamp remains operable when removed from said base;
- and
- a support structure for supporting at least one of the clamp members when the bar clamp is inserted on the base so that the supported clamp member can make contact with a work surface thereby offering additional support to the apparatus.
An apparatus for securing a workpiece, the apparatus comprising:
- a bar clamp having a first clamp member, a second clamp member, and a bar, wherein the clamp members are disposed about the bar and wherein the bar clamp can be configured to operate in at least one of a clamp mode and a spreader mode;
- a base having a mating structure for mating with the bar clamp wherein one of the bar clamp and the base are removable from the other of said bar clamp and said base and wherein the bar clamp remains operable when removed from said base;
- and
- wherein the second clamp member comprises a brake that limits shifting of the second clamp member along the bar in at least one direction and a user operated actuator therefor located above the bar proximate a gripping position and operable to release the brake to allow the clamp to slide along the bar.
An apparatus for securing a workpiece, the apparatus comprising:
- a bar clamp having a first clamp member, a second clamp member, and a bar, wherein the clamp members are disposed about the bar and wherein the bar clamp can be configured to operate in at least one of a clamp mode and a spreader mode;
- a base having a mating structure for mating with the bar clamp wherein one of the bar clamp and the base are removable from the other of said bar clamp and said base and wherein the bar clamp remains operable when removed from said base, a lower base portion for mounting the base to a work surface, and an upper base portion for connecting the base and the bar clamp.
An apparatus for securing a workpiece, the apparatus comprising:
- first and second clamp members;
- a transportable elongate member to which the clamp members are mounted for being shifted between clamped and unclamped positions to allow a clamped workpiece to be transported;
- and
- a base having a clamping portion for being clamped to a substantially stationary surface, and a connecting portion of the base which allows the transportable elongate member to be connected in a fixed position relative to the base to keep the clamped workpiece fixed relative to the stationary surface.
An apparatus for securing a bar to a base assembly comprising:
- a first clamp member;
- a second clamp member positioned opposite the first clamp member and movable with respect to the first clamp member from a bar engaging position wherein the clamp members engage and retain the bar, to a bar disengaging position wherein the clamp members disengage the bar;
- an actuator connected to the second clamp member for moving the second clamp member from one of its bar engaging position and its bar disengaging position to the other of said bar disengaging position and bar engaging position;
- and
- a resilient member connected to the actuator which compensates for over travel of the second clamp member with respect to one of the bar and the first clamp member.
An apparatus for securing a base assembly to a work surface comprising:
- a first clamp member;
- a second clamp member positioned opposite the first clamp member and movable with respect to the first clamp member from a work surface engaging position wherein clamp members engage the work surface to which the apparatus is mounted, to a work surface releasing position wherein the work surface is released from the clamps;
- an actuator connected to the second clamp member for moving the second clamp member from one of the work surface engaging position and the work surface releasing position to the other of said work surface releasing position and work surface engaging position;
- and
- a quick release mechanism connected to the actuator for disengaging the actuator and rapidly shifting the actuator to the work surface releasing position.
