Abstract
Abstract A pipe coupling which includes a housing and a nipple that is provided with locking lugs distributed over the circumference which engage in locking grooves of a grooved socket provided in the housing; the locking grooves thereby extend at first essentially in the axial direction and then essentially in the circumferential direction and are provided at the end of the circumferential section with a notch recessed in the direction toward the end face of the housing on the side of the nipple whereby a locking spring forces the locking lugs into the notches in the completely coupled condition; the grooved socket is thereby freely rotatably arranged within the housing about the axis thereof and is axially fixed with respect to the housing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
201 words
A pipe coupling which comprises grooved socket means contained within a housing means and a nipple means provided with locking lugs distributed over the circumference thereof which are received by locking groove means in said grooved socket means when coupling said nipple means to said housing means, said locking groove means each including a first section extending, as viewed from an end face of the housing means on the nipple-side, essentially in the axial direction and a second section adjoining said first section and extending essentially in the circumferential direction and being provided at the end of the circumferential section opposite where the axially extending section adjoins the first section with a notch means directed toward said end face of the housing means, and a locking spring means in said housing means which forces the locking lugs into said notch means in the coupled condition of said nipple means, characterized in that said grooved socket means is freely rotatable about the axis of the housing means and is axially fixed with respect to said housing means, said grooved socket means being provided with an axial opening, and said nipple means extending axially through said axial opening in said grooved socket means.
Claim 2
Dependent Claim
201 words
A pipe coupling which comprises grooved socket means contained within a housing means and a nipple means provided with locking lugs distributed over the circumference thereof which are received by locking groove means in said grooved socket means when coupling said nipple means to said housing means, said locking groove means each including a first section extending, as viewed from an end face of the housing means on the nipple-side, essentially in the axial direction and a second section adjoining said first section and extending essentially in the circumferential direction and being provided at the end of the circumferential section opposite where the axially extending section adjoins the first section with a notch means directed toward said end face of the housing means, and a locking spring means in said housing means which forces the locking lugs into said notch means in the coupled condition of said nipple means, characterized in that said grooved socket means is freely rotatable about the axis of the housing means and is axially fixed with respect to said housing means, said grooved socket means being provided with an axial opening, and said nipple means extending axially through said axial opening in said grooved socket means.
Claim 3
Dependent Claim
35 words
A pipe coupling according to claim 1, characterized in that the fit between the grooved socket means and the housing means is closer than the fit between the grooved socket means and the nipple means.
Claim 4
Dependent Claim
59 words
A pipe coupling according to claim 1, characterized in that the grooved socket means includes two axial parts, the part disposed further away from said end face of the housing means being constructed as annular disk while the other part disposed nearer the end face of the housing means is constructed as grooved part accommodating the locking groove means.
Claim 5
Dependent Claim
21 words
A pipe coupling according to claim 3, characterized in that said other part is in the form of a cylindrical sleeve.
Claim 6
Dependent Claim
41 words
A pipe coupling according to claim 3, characterized in that each second section of the locking groove means extending in the circumferential direction is formed as a recess in the end face of said grooved part which faces said annular part.
Claim 7
Dependent Claim
51 words
A pipe coupling according to claim 5, characterized in that the boundary surfaces of each second section of the locking groove means extending in the circumferential direction which is located on the side of the groove means opposite said end face of the housing means are formed by said annular part.
Claim 8
Dependent Claim
21 words
A pipe coupling according to claim 6, characterized in that said other part is in the form of a cylindrical sleeve.
Claim 9
Dependent Claim
35 words
A pipe coupling according to claim 6, characterized in that the fit between the grooved socket means and the housing means is closer than the fit between the groove socket means and the nipple means.
Claim 10
Dependent Claim
19 words
A pipe coupling according to claim 3, characterized in that said other part is made from synthetic plastic material.
Claim 11
Dependent Claim
17 words
A pipe coupling according to claiM 9, characterized in that said one part consists of non-ferrous metal.
