Abstract
Abstract Adjustable connector for connecting two tubular bodies such as pipes includes an outer sleeve connectable to one body, an elastically deformable inner sleeve connectable to the other body and accommodated within the outer sleeve and a fastening element to fasten the sleeves and the bodies together while causing elastic deformation of the inner sleeve. Overall pressured embracement of said other body by the inner sleeve deformed by the fastening element assures easy and reliable connection of the two bodies, avoids development of damages on the surfaces of the bodies even after repeated fastening and results in stably durable connection of the two bodies thanks to uniform distribution of fastening pressure over the entire portion of the inner sleeve surface.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
189 words
An adjustable connector comprising: an outer sleeve having an axial through hole formed therein; an inner sleeve having an axial through hole formed therein, said inner sleeve comprising a body portion and an outer flange portion, said body portion having first and second axial ends and adapted to be inserted into said axial through hole of said outer sleeve, said outer flange portion being formed at said first end of said body portion and adapted to act as a stopper for limiting the movement of said inner sleeve into said axial through hole of said outer sleeve, said body portion having a pair of generally axially oriented slots formed in the periphery of said body portion and opening in said second end thereof whereby said body portion may be elastically deformed in a radial direction; and each of said pair of axially oriented slots merges into at least one circumferentially oriented slot formed in said body portion of said inner sleeve. fastening means coupled to said outer sleeve and capable of pressing said body portion of said inner sleeve so as to cause elastic deformation of said body portion
Claim 2
Dependent Claim
189 words
An adjustable connector comprising: an outer sleeve having an axial through hole formed therein; an inner sleeve having an axial through hole formed therein, said inner sleeve comprising a body portion and an outer flange portion, said body portion having first and second axial ends and adapted to be inserted into said axial through hole of said outer sleeve, said outer flange portion being formed at said first end of said body portion and adapted to act as a stopper for limiting the movement of said inner sleeve into said axial through hole of said outer sleeve, said body portion having a pair of generally axially oriented slots formed in the periphery of said body portion and opening in said second end thereof whereby said body portion may be elastically deformed in a radial direction; and each of said pair of axially oriented slots merges into at least one circumferentially oriented slot formed in said body portion of said inner sleeve. fastening means coupled to said outer sleeve and capable of pressing said body portion of said inner sleeve so as to cause elastic deformation of said body portion
Claim 3
Dependent Claim
34 words
An adjustable connector as claimed in claim 1, wherein said inner sleeve has a recess formed in the outer surface of said body portion and wherein a fitting plate is received within said recess.
Claim 4
Dependent Claim
33 words
An adjustable connector as claimed in claim 1, wherein said outer sleeve has a threaded radial through hole and said fastening means includes a fastening screw screwed into said threaded radial through hole.
Claim 5
Dependent Claim
143 words
An adjustable connector comprising: an outer sleeve having an axial through hole formed therein and an inner bulkhead extending longitudinally in said axial through hole; an inner sleeve having an axial through hole formed therein and an outer flange acting as a stopper for positioning the inward movement of said inner sleeve into said axial through hole of said outer sleeve, said inner sleeve further having a pair of generally axially oriented slots formed in the periphery thereof and extending through a sufficient portion of said inner sleeve so as to allow a radial elastic deformation of said inner sleeve, and a radial outer projection to be received in a longitudinal slot formed in said bulkhead of said outer sleeve; and fastening means coupled to said outer sleeve and capable of pressing said inner sleeve so as to cause said radial elastic deformation.
Claim 6
Dependent Claim
143 words
An adjustable connector comprising: an outer sleeve having an axial through hole formed therein and an inner bulkhead extending longitudinally in said axial through hole; an inner sleeve having an axial through hole formed therein and an outer flange acting as a stopper for positioning the inward movement of said inner sleeve into said axial through hole of said outer sleeve, said inner sleeve further having a pair of generally axially oriented slots formed in the periphery thereof and extending through a sufficient portion of said inner sleeve so as to allow a radial elastic deformation of said inner sleeve, and a radial outer projection to be received in a longitudinal slot formed in said bulkhead of said outer sleeve; and fastening means coupled to said outer sleeve and capable of pressing said inner sleeve so as to cause said radial elastic deformation.
Claim 7
Dependent Claim
29 words
An adjustable connector as claimed in claim 4, wherein each of said pair of axially oriented slots merges into a respective circumferentially oriented slot formed in said inner sleeve.
Claim 8
Dependent Claim
37 words
The adjustable connector as claimed in claim 4, wherein said outer sleeve has a radial threaded through hole and said fastening means includes a fastening screw screwed into said radial threaded through hole of said outer sleeve.
Claim 9
Dependent Claim
193 words
An adjustable connector comprising: an outer sleeve having an axial through hole formed therein; an inner sleeve having an axial through hole formed therein, said inner sleeve comprising a body portion and an outer flange portion, said body portion having first and second axial ends and adapted to be inserted into said axial through hole of said outer sleeve, said outer flange portion being formed at said first end of said body portion and adapted to act as a stopper for limiting movement of said inner sleeve into said axial through hole of said outer sleeve, said body portion having a pair of generally axially oriented slots formed in the periphery of said body portion and opening in said second end of said body portion whereby said body portion may be elastically deformed in a radial direction and a recess formed in the outer surface of said body portion; a fitting plate accommodated within said recess of said body portion of said inner sleeve; and fastening means coupled to said outer sleeve and capable of pressing said body portion of said inner sleeve so as to cause elastic deformation of said body portion.
