Abstract
The present invention relates to bar clamps, and more specifically, to attachments for extending the length of such clamps and enabling such clamps to be adaptable to a wider array of clamping needs. The accessories include an extension bar, a coupling that attaches one end of the extension bar to the clamp primary bar locking the bars in longitudinal alignment, and a stop that attaches to the primary bar or extension for fixing the location of a clamp jaw along the bars.
Claims12
In a bar clamp extension for extending the length of a bar clamp assembly which includes a primary bar having a distal end and a proximal end, a releasably mounted jaw on the distal end of the primary bar, a relatively moveable jaw attached to the proximal end section of the primary bar, the improvement comprising:
- an extension bar having a proximal end and a distal end;
- and
- coupling means at the proximal end of the extension bar for releasably attaching the extension bar to the distal end of the primary bar in longitudinal alignment, the coupling means including a cylindrical body with a proximal end configured to receive the end of the primary bar and a distal end fixed to the proximal end of the extension bar, and a hollow sleeve having a proximal end and a distal end and configured to be slideably received over the cylindrical body surrounding the respective ends of the primary bar and the extension bar received by the body.
In a bar clamp assembly with at least one clamp bar having a distal end and a proximal end, a releasably mounted jaw on the distal end of the primary bar, a relatively moveable jaw attached to the proximal end section of the primary bar, the improvement comprising:
- a first sleeve and a second sleeve slideably mounted on the clamp bar for securing the fixed jaw at selective locations along the clamp bar.
