Abstract: A mechanism for changing a pitch of a string of an electric guitar having a string supporting bridge mounted on the guitar body, and said bridge having a transverse flange. To be inexpensive and easy to mount on the guitar without requiring neither removal of components from the guitar nor making of new holes in the guitar body, the mechanism comprises a base, an actuating lever device pivotally attached to said base and including string engagement means for connecting a first one of the guitar strings thereto and for varying tension on said first one of the strings by pivoting said actuating lever device relative to said base, and clamping means carried by said base and operable to removably clamp said base to said flange.

Abstract: The present invention relates to a snap-type locking device for releasable and principally external keeping together of two parts and comprising at least one grip part at least one grip part, at least one movable arm and at least one spring, said at least one movable arm being turnably attached to said at least one grip part as well as, directly or indirectly, to a first part of said two parts. Said at least one spring abuts said at least one grip part in order to urge the same in a direction away from said two parts.

Abstract: The present invention relates to a tool for pipe bending comprising at least two branches (1, 3), at least one link arm (8), at least one former (7), and at least one sliding jaw (9), said at least one former (7) and said at least one sliding jaw (9) being intended to be placed on either side of a pipe (12) to be bent, and said at least one former (7) being fitted to, or constituting a part of, a first branch (1) of said at least two branches (1, 3) at the same time as said at least one sliding jaw (9) being fitted to, or constituting a part of, a second branch (3) of said at least two branches (1, 3). At least one of said at least one former (7) has at least one pipe-positioning index (18, 19), one of which is intended to be placed as close as possible to a corresponding bending-measure index on the pipe (12) when the pipe (12) is placed in the tool in order to be bent. The present invention also relates to a former (7) for use as a part of a tool for pipe bending.

Abstract: The present invention relates to a snap-type locking device for releasable and principally external keeping together of two parts (1, 2) and comprising at least one grip pat (11, 11a, 18, 20, 21, 22), at least one movable arm (12, 12a, 12b) and at least one spring (14, 14a, 14b, 14c), said at least one movable arm (12, 12a, 12b) being turnably attached to said at least one grip part (11, 11a, 18, 20, 21, 22) as well as, directly or indirectly, to a first part (1)of said two parts (1, 2). Said at least one spring (14, 14a, 14b, 14c) abuts against said at least one grip part (11, 11a; 18, 20, 21, 22) in order to urge the same in a direction away from said two parts (1, 2).

Abstract: The present invention relates to a case comprising at least one partition wall. Said at least one partition wall is dismountable and useful as a sitting and/or knee cushion.
