Clamp-type hand tool
In order to improve a clamp-type hand tool, comprising a first arm incorporating a corresponding jaw portion and a second arm incorporating a corresponding jaw portion wherein the two arms are pivotable relative to one another and the jaw portions form a jaw device having an adjustable aperture, in such a manner that it is employable in as universal a way as possible, it is proposed that the jaw portion of the first arm and/or the law portion of the second arm be displaceable on the corresponding arm.
1. A clamp-type hand tool, comprising:
a first arm with a corresponding jaw portion; and
a second arm with a corresponding jaw portion;
wherein:
the two arms are pivotable relative to one another;
the jaw portions form a jaw device having an adjustable aperture; and
at least one of: (i) the jaw portions of the first arm is displaceable on the first arm and (ii) the jaw portion of the second arm is displaceable on the second arm.
2. A clamp-type hand tool in accordance with claim 1 , wherein the displaceable jaw portion is displaceable away from the other jaw portion or is displaceable towards the other jaw portion.
3. A clamp-type hand tool in accordance with claim 1 , wherein the size of the aperture of the jaw device is adjustable by means of the displaceable jaw portion.
4. A clamp-type hand tool in accordance with claim 1 , wherein the clamping force effective on one or more work-pieces that are clamped in the jaw is adjustable by means of the displaceable jaw portion.
5. A clamp-type hand tool in accordance with claim 1 , wherein the displaceable jaw portion is adapted to be displaced and fixed on the corresponding arm.
6. A clamp-type hand tool in accordance with claim 1 , wherein the direction of displacement of the displaceable jaw portion is transverse to a pivot axis for the first arm and the second arm.
7. A clamp-type hand tool in accordance with claim 1 , wherein the direction of displacement of the displaceable jaw portion is transverse to the longitudinal direction of a handle portion of the corresponding arm.
8. A clamp-type hand tool in accordance with claim 1 , wherein a slide rail is provided for the displaceable jaw portion.
9. A clamp-type hand tool in accordance with claim 8 , wherein the slide rail extends transversely relative to a handle portion of the corresponding arm.
10. A clamp-type hand tool in accordance with claim 8 , wherein the slide rail is connected to a handle portion of the corresponding arm.
11. A clamp-type hand tool in accordance with claim 8 , wherein the displaceable jaw portion is in the form of a sliding bracket which is guided on the slide rail.
12. A clamp-type hand tool in accordance with claim 11 , wherein the sliding bracket is fixable on the slide rail in releasable manner by means of a clamping force.
13. A clamp-type hand tool in accordance with claim 12 , wherein one or more elastic elements are provided in order to hold the sliding bracket on the slide rail.
14. A clamp-type hand tool in accordance with claim 13 , wherein at least one springy tongue element is provided which presses the sliding bracket on to the slide rail.
15. A clamp-type hand tool in accordance with claim 14 , wherein the tongue element is arranged on the sliding bracket.
16. A clamp-type hand tool in accordance with claim 15 , wherein the tongue element is formed in a one-piece manner with the sliding bracket.
17. A clamp-type hand tool in accordance with claim 9 , wherein the sliding bracket comprises at least one latching element and the slide rail comprises matching seatings, whereby a displacement of the sliding bracket is blocked if the at least one latching element has entered into a seating.
18. A clamp-type hand tool in accordance with claim 17 , wherein a row of seatings is provided along the slide rail in the direction of displacement.
19. A clamp-type hand tool in accordance with claim 17 , wherein the seatings and a surface, upon which a force-exerting element is effective, are arranged at opposite sides of the slide rail.
20. A clamp-type hand tool in accordance with claim 17 , wherein the seatings have side faces which are inclined with respect to the direction of displacement.
21. A clamp-type hand tool in accordance with claim 8 , wherein the slide rail is provided with a graduated scale.
22. A clamp-type hand tool in accordance with claim 8 , wherein the slide rail is arranged on the corresponding arm in fixable and displaceable manner.
23. A clamp-type hand tool in accordance with claim 22 , wherein the displaceable jaw portion is firmly seated on the displaceable slide rail.
24. A clamp-type hand tool in accordance with claim 22 , wherein the displaceable jaw portion is seated on the displaceable slide rail in a fixable and displaceable manner.
25. A clamp-type hand tool in accordance with claim 22 , wherein the corresponding arm comprises a guidance recess for the slide rail.
26. A clamp-type hand tool in accordance with claim 1 , wherein a spring is arranged between the first arm and the second arm.
27. A clamp-type hand tool in accordance with claim 26 , wherein the spring is arranged and constructed in such a manner that an external force must be expended in order to pivot the arms relative to one another when enlarging the aperture of the jaw device.
28. A clamp-type hand tool in accordance with claim 26 , wherein the spring is arranged and constructed in such a manner that the arms exert a clamping force on one or more work-pieces which are located between the jaw portions of the two arms.
29. A clamp-type hand tool in accordance with claim 1 , wherein a jaw piece for a work-piece is arranged, in moveable manner, on the jaw portion of at least one of the first arm and the second arm.
