Definitions

  • This invention relates to a bar clamp of the type used to temporarily clamp together two articles, for example, for gluing, or to hold a work piece for welding. More particularly, it relates to a specific type of quick-action bar wherein a movable jaw can be rapidly or incrementally advanced using just one hand, thereby leaving the user's other hand free to hold the articles being clamped. The clamp therefore can be completely controlled and adjusted using just one hand.
  • the clamp is activated by a user squeezing a trigger which acts against the driving plate via a cam motion to advance the movable jaw forward on the slide bar toward the fixed jaw.
  • the movable jaw advances forward by sliding through the braking plate.
  • the braking plate allows free movement in the direction toward the fixed jaw or “forward” direction, but then clamps against the slide bar via a binding interference to prevent the movable jaw from sliding away from the fixed jaw or "backwards” direction.
  • the incremental steps of release-advance-and-then-binding-again, used to advance the movable jaw, can be advanced a full step, or cycle of the driving plate and braking plate. Once the movable jaw contacts the article to be clamped and is not able to take one more full “step,” however, it is unable to exert additional clamping force against the article. Even when the user applies considerable force against the trigger, the mechanism has too much inherent loss between the binding and free-sliding states of the driving and braking plates and the movable jaw is not able to move any further along the slide bar to create additional clamping force.
  • the present invention solves the above problems with current quick action clamps by including an additional lever that allows the user to apply a much greater clamping force against the articles being clamped, in an amount sufficient to hold the articles more securely for subsequent operations such as sawing, drilling, filing, bending, etc.
  • the present invention is comprised of an improved quick action clamp which includes an additional lever that allows the user to apply a much greater clamping force against the articles being clamped, in an amount sufficient to hold the articles more securely for subsequent operations such as sawing, drilling, filing, bending, etc.
  • At least one additional lever may be attached at various points to the quick action clamp and when engaged by the user to apply an additional clamping force to further secure the article being clamped.
  • the at least one additional lever is attached adjacent to the braking plate such that when the additional lever is engaged by the user, the additional lever acts via a cam to apply a force upon the braking plate causing the movable jaw to advance toward the fixed jaw in a smooth movement and an additional distance.
  • the at least one additional lever is actuated via a cam, or similar method such as a screw, which applies force smoothly and incrementally, rather than in the stepped release-advance- reengage fashion of the binding braking plate, the clamping pressure can be released without applying additional forward pressure.

  • the present invention is an improvement over quick action bar clamps by including at least one additional and separate clamping lever which is used to apply incremental clamping force once the movable jaw has contacted the article to be clamped.
  • FIG. 1 shows a general view of a preferred embodiment of the improved quick action bar clamp 1.
  • the present invention includes a movable jaw 3 connected to a slide bar 5.
  • the slide bar 5 passes through an opening (not shown) in the housing 9.
  • the housing 9 supports a trigger handle 11 extending downwardly from the housing 9 and is used by the user to activate the quick action bar clamp 1.

  • the braking plate 15 is connected to the portion of the housing most proximal to the fixed jaw 19 by at least one spring 17 extending from the top portion of the trigger handle 11 to the rear side of brake plate 21.
  • the opening (not shown) through which the slide bar 5 extends is sized so that the braking plate 15 engages the slide bar 5 to prevent movement of the movable jaw 3 in the direction away from the fixed jaw 23.
  • the braking plate 15 allows free movement in the direction toward a fixed jaw 23 or "forward” direction, but then clamps against the slide bar 5 via a binding interference to prevent the movable jaw 3 from sliding away from the fixed jaw 23 or "backwards" direction.
  • At least one driving plate 25 is placed around the slide bar 5.
  • At least one spring 27 allows the driving plate 25 to move in the direction of the fixed jaw 23 when the trigger handle 11 is squeezed by the user.
  • the driving plate 25 allows the movable jaw 3 to advance along a slide bar 5 incrementally similar to an "inch worm" type of movement.
