Abstract
A coupling rod fitting (1) having a first end piece (2); a second end piece (3); and having an intermediate piece (4) which connects the first end piece (2) and the second end piece (3). The intermediate piece (4) is formed as a connecting rod and the first end piece (2) and the second end piece (3) have in each case one sleeve (5 and 6 respectively), which sleeves are pushed onto the connecting rod (4) and are fixed in an adjustable final assembly position on the connecting rod (4).
Claims8
A coupling rod fitting (1) adjustable in axial length, comprising
- a first end piece (2) including a first connector;
- a second end piece (3) including a second connector;
- and
- a connecting rod (4) having a first end and a second end,
- wherein the connecting rod (4) first end and second ends are cylindrical,
- wherein the first end piece (2) is assembled from two sheet-metal halves (9, 10) together forming a sleeve (5) with a cylindrical recess adapted to receiving the connecting rod (4) first end,
- wherein the second end piece (3) is assembled from two sheet-metal halves (11, 12) together forming has a sleeve (6) with a cylindrical recess adapted to receiving the connecting rod (4) second end,
- wherein the sleeves (5, 6) have in each case an axially elongate welding window (7 and 8 respectively) between the two sheet-metal halves (9, 10 and 11, 12 respectively),
- wherein the coupling rod fitting (1) is adapted for forming a coupling rod by pushing the sleeves (5, 6) at least part way onto the first and second ends of the connecting rod (4), wherein the sleeves (5, 6) are adapted to be fixed to the connecting rod (4) by means of a cohesive connection through the axially elongate welding windows, and wherein the effective length of the coupling rod is adapted to be varied by varying the final assembly position of the sleeves (5, 6) on the connecting rod (4) and by varying the position of the cohesive connection on the end pieces (2, 3) and on the connecting rod (4).
