Abstract
Abstract A connection arrangement between a pipe stub and a hose surrounding the same which includes an axially symmetrical clamping member surrounding the hose and, axially on both sides thereof one sleeve-like clamping nut or collar with sections of hollow cylindrical shape which are directly adjacent one another; the two sleeve-like clamping nuts or collars can be tightened with each other so that the clamping member which consists of a deformable and simultaneously substantially non-compressible material, is pressed against the outer surface of the hose thereby establishing the connection; external grooves may be provided on the outer surface of the clamping member which extend approximately parallel to the axis.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
141 words
A connecting device between a pipe stub and a flexible hose surrounding said stub, comprising a substantially axially symmetrical clamping means surrounding said hose and two clamping collar means which are arranged axially at each end of said clamping means and which are adapted to be axially tightened with each other, said clamping collar means having axial portions of substantially hollow cylindrical form which face one another, characterized in that the clamping means consists of a deformable, yet substantially non-compressible material, and in that the outer surface of the clamping means is provided with groove means that extend at least approximately parallel to the axis and have a depth smaller than the radial thickness of the clamping means within the areas thereof devoid of groove means so that a cOntinuous internal surface is provided by the clamping means which is uninterrupted.
Claim 2
Dependent Claim
141 words
A connecting device between a pipe stub and a flexible hose surrounding said stub, comprising a substantially axially symmetrical clamping means surrounding said hose and two clamping collar means which are arranged axially at each end of said clamping means and which are adapted to be axially tightened with each other, said clamping collar means having axial portions of substantially hollow cylindrical form which face one another, characterized in that the clamping means consists of a deformable, yet substantially non-compressible material, and in that the outer surface of the clamping means is provided with groove means that extend at least approximately parallel to the axis and have a depth smaller than the radial thickness of the clamping means within the areas thereof devoid of groove means so that a cOntinuous internal surface is provided by the clamping means which is uninterrupted.
Claim 3
Dependent Claim
141 words
A connecting device between a pipe stub and a flexible hose surrounding said stub, comprising a substantially axially symmetrical clamping means surrounding said hose and two clamping collar means which are arranged axially at each end of said clamping means and which are adapted to be axially tightened with each other, said clamping collar means having axial portions of substantially hollow cylindrical form which face one another, characterized in that the clamping means consists of a deformable, yet substantially non-compressible material, and in that the outer surface of the clamping means is provided with groove means that extend at least approximately parallel to the axis and have a depth smaller than the radial thickness of the clamping means within the areas thereof devoid of groove means so that a cOntinuous internal surface is provided by the clamping means which is uninterrupted.
Claim 4
Dependent Claim
141 words
A connecting device between a pipe stub and a flexible hose surrounding said stub, comprising a substantially axially symmetrical clamping means surrounding said hose and two clamping collar means which are arranged axially at each end of said clamping means and which are adapted to be axially tightened with each other, said clamping collar means having axial portions of substantially hollow cylindrical form which face one another, characterized in that the clamping means consists of a deformable, yet substantially non-compressible material, and in that the outer surface of the clamping means is provided with groove means that extend at least approximately parallel to the axis and have a depth smaller than the radial thickness of the clamping means within the areas thereof devoid of groove means so that a cOntinuous internal surface is provided by the clamping means which is uninterrupted.
Claim 5
Dependent Claim
25 words
A connecting device according to claim 1, characterized in that the material of the clamping means is harder than the material of the flexible hose.
Claim 6
Dependent Claim
37 words
A connecting device according to claim 2, characterized in that the material of the clamping means is selected from the group consisting of nylon, synthetic hard rubber, natural rubber, plastic or pressed material, lead and non-ferrous alloys.
Claim 7
Dependent Claim
24 words
A connecting device according to claim 2, characterized in that the internal surface of the clamping means, in the non-tightened condition, is continuously smooth.
Claim 8
Dependent Claim
71 words
A connecting device according to claim 4, characterized in that the remaining radial material thickness of the clamping means within the area of the groove means is smaller than the material thickness in the area of the remaining portions thereof by such an extent that, in the tightened condition of the clamping means, inwardly protruding bulges are formed in the area of the groove means, which prevent damage to the hose.
Claim 9
Dependent Claim
17 words
A connecting device according to claim 5, characterized in that said clamping means essentially consists of nylon.
Claim 10
Dependent Claim
39 words
A connecting device according to claim 1, characterized in that the internal surface of the clamping means formed by alternating portions of the clamping means devoid of and provided with groove means, is continuously smooth in the non-tightened condition.
Claim 11
Dependent Claim
71 words
A connecting device according to claim 7, characterized in that the remaining radial material thickness of the clamping means within the area of the groove means is smaller than the material thickness in the area of the remaining portions thereof by such an extent that, in the tightened condition of the clamping means, inwardly protruding bulges are formed in the area of the groove means, which prevent damage to the hose.
Claim 12
Dependent Claim
17 words
A connecting device according to claim 1, characterized in that said clamping means essentially consists of nylon.
Claim 13
Dependent Claim
142 words
A connecting device between a pipe stub and a flexible hose surrounding said stub, comprising a substantially axially symmetrical clamping means surrounding said hose and two clamping collar means which are arranged axially at each end of said clamping means and which are adapted to be axially tightened with each other, said clamping collar means having axial portions of substantially hollow cylindrical form which face one another, characterized in that the clamping means consists of a deformable, yet substantially non-compressible material, and in that the clamping means is provided with groove means extending in a direction approximately parallel to the axis from the outer surface thereof inwardly to a point spaced from the inner surface thereof so that the portions devoid of groove means are connected with each other along the inner surface by the remaining portions left by the groove means.
Claim 14
Dependent Claim
142 words
A connecting device between a pipe stub and a flexible hose surrounding said stub, comprising a substantially axially symmetrical clamping means surrounding said hose and two clamping collar means which are arranged axially at each end of said clamping means and which are adapted to be axially tightened with each other, said clamping collar means having axial portions of substantially hollow cylindrical form which face one another, characterized in that the clamping means consists of a deformable, yet substantially non-compressible material, and in that the clamping means is provided with groove means extending in a direction approximately parallel to the axis from the outer surface thereof inwardly to a point spaced from the inner surface thereof so that the portions devoid of groove means are connected with each other along the inner surface by the remaining portions left by the groove means.
