Abstract The invention relates to a sleeve (1) for interconnecting rods (3, 5) provided with threads. The sleeve (1) has an opening in each end, said openings preferably having a different size and/or form. The inside form of the sleeve (1) is such that when the rods (3, 5) are combined to a mutual threaded engagement the sleeve (1) can be axially fitted to the overlapping area of the combined rods (3, 5). The inside dimension of the sleeve (1) is such that it makes separation of the rods (3, 5) in their position fitted on the overlapping area impossible as well as elimination of the mutual thread engagement. The sleeve (1) enables a rapid, simple and reliable joining of rods (3, 5) provided with threads with a free choice of the length of the overlapping area.
A sleeve for interconnecting threaded rods, comprising: sleeve means for retaining together said threaded rods when said rods are in mutually threaded engagement with each other so as to allow said rods to be freely rotated with respect to each other, said sleeve means being sufficiently narrow to prevent said rods from becoming disengaged from each other while said rods are within said sleeve means; one end of said sleeve means being partially closed assymetrically with respect to its longitudinal axis so s to allow only one rod to extend therethrough.

A sleeve for interconnecting threaded rods, comprising: sleeve means for retaining together said threaded rods when said rods are in mutually threaded engagement with each other so as to allow said rods to be freely rotated with respect to each other, said sleeve means being sufficiently narrow to prevent said rods from becoming disengaged from each other while said rods are within said sleeve means; one end of said sleeve means being partially closed assymetrically with respect to its longitudinal axis so s to allow only one rod to extend therethrough.
Claim 3
Dependent Claim
16 words
The sleeve according to claim 1, wherein said sleeve is adapted to retain two rods together.
Claim 4
Dependent Claim
47 words
The sleeve according to claim 1, wherein the inside form of the sleeve is adapted to the outer contour of the overlapping area of the rods provided with threads so that the rods are mutually fixed substantially rigidly except for their rotating ability about their longitudinal axes.
Claim 5
Dependent Claim
25 words
The sleeve according to claim 1, wherein the other end of said sleeve means is open such that all of said rods may extend therethrough.
Claim 6
Dependent Claim
15 words
The sleeve according to claim 1, further comprising an inspection window at the one end.
Claim 7
Dependent Claim
