Turnbuckle
First Claim
1. A turnbuckle comprising:
- first and second fastening parts, said first fastening part having a first end fitting and a first rod-shaped portion, said second fastening part having a second end fitting and a second rod-shaped portion, at least said first rod-shaped portion being formed with external threads; and
a tightening device including first and second tightening members in telescoping relationship with each other, each tightening member having an outer end piece and an inner end piece,wherein the outer end piece of at least said first tightening member has a threaded through-hole therein, said first rod-shaped portion being in screw engagement with said through-hole,said inner end piece of said second tightening member is formed with a threaded through-hole for screw engagement with said first rod-shaped portion, andsaid tightening device is constructed to assume at least a shorter and a longer elongation condition, so that, in the shorter condition, said first rod-shaped portion is in screw engagement with the threaded through-hole of the inner end piece of said second tightening member and, in the longer condition, said first rod-shaped portion is not in screw engagement with the threaded through-hole of the inner end piece of said second tightening member, a spacing between the outer end pieces of the first and second tightening members in a longitudinal direction of the tightening device is greater than said spacing in the shorter condition, and the inner end pieces of said first and second tightening members are in abutting relationship.

Abstract
A turnbuckle comprises first and second fastening parts, the first fastening part having a first end fitting and a first rod-shaped portion, and the second fastening part having a second end fitting and a second rod-shaped portion, at least the first of which rod-shaped portions is formed with threads. The turnbuckle further comprises a tightening device comprising first and second tightening members, each having an outer end piece and an inner end piece. The outer end piece of at least the first tightening member has a threaded through-hole to receive in screw engagement the threaded rod portion of the first fastening part. The inner end piece of the second tightening member has a threaded through-hole also to receive in screw engagement the threaded rod portion of the first fastening part. The tightening device is arranged to assume at least two different elongation conditions. In a shorter condition, the inner end piece of the second tightening member is engaged with the threaded rod portion of the first fastening part. In a longer condition, the inner end piece of the second tightening member is not so engaged, but the tightening members are longitudinally displaced such that the inner end pieces of the first and second tightening members abut each other.
