Abstract
Abstract A self-supporting transmission line carrier between a moveable consumer and a stationary connection comprising a row of tubular members of any selected cross-sectional shape which are pivotally connected with one another and engage in one another. The tubular members are angled-off from the extended position only in one direction, in a manner whereby the angling-off of the tubular members is limited relative to one another by means of abutments. Each tubular member on one end has an inwardly rimming, circulatory channel, the outwardly angled-off edge of which forms the inner abutment. Each tubular member is shortened on the other end on one half by the width of the channel and has a circulatory inwardly directed angled-off edge which forms the outer abutment. Two adjacent tubular members engage behind one another with their inner and outer abutments and the maximum angling-off is fixed by the width of the channel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
A self-supporting transmission line carrier between a moveable consumer and a stationary connection comprising a row of tubular members of any selected cross-sectional shape operatively pivotally connected relative to one another and engaging in one another, said tubular members bending relative to one another from an extended position thereof only in one direction, each of said tubular members being formed on one end with an inwardly directed rimming, circulatory channel having an outwardly directed angled-off edge forming an inner abutment, each of said tubular members being shorter at the other end on one half thereof by the width of said channel and having a circulatory inwardly directed angled-off edge forming an outer abutment, the bending of the tubular members being limited relative to one another by means of said abutments, each two adjacent of said tubular members engaging behind one another with said inner and outer abutments, the latter moveably disposed relative to one another, and the bending being limited thereby to a maximum by the width of said channel.
Claim 2
Dependent Claim
170 words
A self-supporting transmission line carrier between a moveable consumer and a stationary connection comprising a row of tubular members of any selected cross-sectional shape operatively pivotally connected relative to one another and engaging in one another, said tubular members bending relative to one another from an extended position thereof only in one direction, each of said tubular members being formed on one end with an inwardly directed rimming, circulatory channel having an outwardly directed angled-off edge forming an inner abutment, each of said tubular members being shorter at the other end on one half thereof by the width of said channel and having a circulatory inwardly directed angled-off edge forming an outer abutment, the bending of the tubular members being limited relative to one another by means of said abutments, each two adjacent of said tubular members engaging behind one another with said inner and outer abutments, the latter moveably disposed relative to one another, and the bending being limited thereby to a maximum by the width of said channel.
Claim 3
Dependent Claim
35 words
The transmission line carrier according to claim 1, wherein each tubular member comprises an upper part and a lower part, said lower part is shorter than said upper part by the width of said channel.
Claim 4
Dependent Claim
27 words
The transmission line carrier according to claim 2, further comprising tabs on one of said parts, said tabs are spot welded on the other of said parts.
Claim 5
Dependent Claim
27 words
The transmission line carrier according to claim 2, further comprising tabs on one of said parts, said tabs are projection welded on the other of said parts.
Claim 6
Dependent Claim
29 words
The transmission line carrier according to claim 2, further comprising a spacer means engages in said channel in the range of said lower part for reducing the maximum bending.
Claim 7
Dependent Claim
17 words
The transmission line carrier according to claim 1, wherein said tubular members are formed with air slots.
Claim 8
Dependent Claim
27 words
The transmission line carrier according to claim 1, wherein said tubular members are made of a thin metal sheet, a synthetic material coats said thin metal sheet.
Claim 9
Dependent Claim
26 words
The transmission line carrier according to claim 1, wherein said tubular members are injection molded in one piece of a synthetic material and are formed assembleable.
Claim 10
Dependent Claim
19 words
The transmission line carrier according to claim 1, wherein said one half constitutes a lower half of said members.
