Abstract
Abstract A connecting apparatus having a pair of connector elements each having an end piece to which a line, such as a rope or a cable etc. is connected, and which has a complemental opposed end face so as to come into contact with each other without relative rotation therebetween. The end pieces are connected together in and by a nut member. One of the end pieces has an outer peripheral threaded portion which can be screwed in the nut member.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
172 words
A connecting apparatus for lines comprising: a pair of connector elements having end pieces which have opposed end faces, said opposite end faces of said pair of connector elements coming into abutting contact with each other, said end faces having a plurality of complemental shapes to each other, at least one of said end pieces being provided with an outer peripheral threaded portion and the other end piece being provided with an abutment; and a nut member in which said end pieces can be inserted so that said threaded portion of the end piece is screwed in the nut member, said nut member being provided with a counter abutment which can be engaged by said abutment of the end piece, so that, when the end pieces are inserted in the nut member, the end pieces can be integrally connected in and to the nut member by the screw engagement between the threaded portion of the end piece and the nut member and by the engagement between said abutment and the counter abutment.
Claim 2
Dependent Claim
172 words
A connecting apparatus for lines comprising: a pair of connector elements having end pieces which have opposed end faces, said opposite end faces of said pair of connector elements coming into abutting contact with each other, said end faces having a plurality of complemental shapes to each other, at least one of said end pieces being provided with an outer peripheral threaded portion and the other end piece being provided with an abutment; and a nut member in which said end pieces can be inserted so that said threaded portion of the end piece is screwed in the nut member, said nut member being provided with a counter abutment which can be engaged by said abutment of the end piece, so that, when the end pieces are inserted in the nut member, the end pieces can be integrally connected in and to the nut member by the screw engagement between the threaded portion of the end piece and the nut member and by the engagement between said abutment and the counter abutment.
Claim 3
Dependent Claim
26 words
An apparatus according to claim 1, wherein said end pieces have a plurality of complemental projections and a plurality of recesses on their opposed end faces.
Claim 4
Dependent Claim
40 words
An apparatus according to claim 1, wherein said abutment is made of an annular shoulder face provided on one of the end pieces and wherein said counter abutment is made of a restricted end face provided on the nut member.
Claim 5
Dependent Claim
20 words
An apparatus according to claim 1, wherein each of said end pieces has a rope connected thereto, made of strands.
Claim 6
Dependent Claim
33 words
An apparatus according to claim 1, wherein ropes are connected to the respective end pieces, so that strands of said rope are frayed and spread in the end pieces together with an adhesive.
Claim 7
Dependent Claim
22 words
An apparatus according to claim 1, wherein at least one of said end pieces has, at its one end, an eye piece.
Claim 8
Dependent Claim
22 words
An apparatus according to claim 1, wherein at least one of said end pieces has, at its one end, a connecting jaw.
Claim 9
Dependent Claim
18 words
An apparatus according to claim 1, wherein each of said end pieces comprises a substantially cylindrical hollow body.
Claim 10
Dependent Claim
199 words
A connecting apparatus for lines comprising: a pair of connecting elements having end pieces which have opposed complimentary end faces, each end face having a plurality of projections and a plurality of recesses, said plurality of projections and said plurality of recesses being complemental to each other, said opposed end faces coming into abutting contact by having said plurality of projections of one end face abut said plurality of recesses on the other end face, at least one of said end pieces being provided with an outer peripheral threaded portion and the other end piece being provided with an abutment; and a nut member in which said end pieces can be inserted so that said threaded portion of the end piece is screwed in the nut member, said nut member being provided with a counter abutment which can be engaged by said abutment of the end piece, so that, when the end pieces are inserted in the nut member, the end pieces can be integrally connected in and to the nut member by the screw engagement between the threaded portion of the end piece and the nut member and by the engagement between said abutment and the counter abutment.
Claim 11
Dependent Claim
199 words
A connecting apparatus for lines comprising: a pair of connecting elements having end pieces which have opposed complimentary end faces, each end face having a plurality of projections and a plurality of recesses, said plurality of projections and said plurality of recesses being complemental to each other, said opposed end faces coming into abutting contact by having said plurality of projections of one end face abut said plurality of recesses on the other end face, at least one of said end pieces being provided with an outer peripheral threaded portion and the other end piece being provided with an abutment; and a nut member in which said end pieces can be inserted so that said threaded portion of the end piece is screwed in the nut member, said nut member being provided with a counter abutment which can be engaged by said abutment of the end piece, so that, when the end pieces are inserted in the nut member, the end pieces can be integrally connected in and to the nut member by the screw engagement between the threaded portion of the end piece and the nut member and by the engagement between said abutment and the counter abutment.
Claim 12
Dependent Claim
27 words
