Abstract
Abstract A device for producing an installation template for conduits, especially conduits for hydraulic or pneumatic switching or operating circuits. The device includes a plurality of relatively short articulated elements that are connected or connectable to one another. Adjacent articulated elements can be respectively moved relative to one another about a common geometrical point of rotation and within a predetermined spatial angle, and can be fixed in any possible position relative to one another. In addition, the device has end pieces that are associated with the articulated elements and are connected or can be connected to the latter, with these end pieces being provided with connectors for rod elements. Finally, the device has rod elements that are several times longer than the articulated elements, and that are provided with connectors that correspond to the connectors on the end pieces.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
242 words
A device to simplify assembly of even complex conduit systems for pressure-medium-driven switching or operating circuits for producing an installation template for conduits employed to arrive at precise measurement of length of said conduits and also to permit marking of conduit sections to be bent to a specific shape in motor vehicle industry as well as for processing and working machinery of various kinds, comprising: a plurality of interconnectable articulated elements, each of which is relatively short compared to the length of said template; adjacent ones of said articulated elements can be respectively moved, relative to one another, about a common geometrical point of rotation and within a predetermined spatial angle;, said articulated elements can be fixed in any position relative to one another by clamping; end pieces which are respectively connectable to given ones of said articulated elements; in addition, each of said end pieces is provided with connecting means on a side thereof remote from said articulated elements, with said given ones of said articulated elements each having a planar abutment surface for engagement with said end pieces; and rod elements, each of which has a length that is several times greater than its diameter; each of said rod elements is provided with connecting means for cooperating with said connecting means of said end pieces so that said articulated elements can be kept in position to conform to various installation requirements although readily adaptable different configurations of employment undertaken therewith.
Claim 2
Independent Claim

Claim 3
Dependent Claim
77 words
A device according to claim 1, in which each of said articulated elements has a ball section and a socket, with said socket having an outer edge remote from said ball section, and with said ball section having a circular shoulder which cooperates with said outer edge of an adjacent socket of a different one of said articulated elements to effect said predetermination of the spatial angle of movement of said articulated elements relative to one another.
Claim 4
Dependent Claim
44 words
A device according to claim 2, in which the socket of a given articulated element is seated on the ball section of an adjacent articulated element under stress to effect said clamping for fixing the position of said articulated elements relative to one another.
Claim 5
Dependent Claim
37 words

Claim 6
Dependent Claim
22 words
A device according to claim 1, in which said articulated elements, said end pieces, and said rod elements are made of plastic.
Claim 7
Dependent Claim
14 words
A device according to claim 5, in which said plastic is a polyamide resin.
Claim 8
Dependent Claim
30 words
A device according to claim 3, in which at least one of said ball section and said socket of a given articulated element is provided with at least one slit.
Claim 9
Independent Claim
164 words
A device for producing an installation template for conduits, comprising: a plurality of interconnectable articulated elements, each of which is relatively short compared to the length of said template; adjacent ones of said articulated elements can be respectively moved, relative to one another, about a common geometrical point of rotation and within a predetermined spatial angle; said articulated elements can be fixed in any position relative to one another by clamping; end pieces which are respectively connectable to given ones of said articulated elements; in addition, each of said end pieces is provided with connecting means on a side thereof remote from said articulated elements; rod elements, each of which has a length that is several times greater than its diameter; each of said rod elements is provided with connecting means for cooperating with said connecting means of said end pieces; each of said rod elements comprising two telescoping parts, and clamping means for holding said parts in any position relative to one another.
Claim 10
Independent Claim
164 words
A device for producing an installation template for conduits, comprising: a plurality of interconnectable articulated elements, each of which is relatively short compared to the length of said template; adjacent ones of said articulated elements can be respectively moved, relative to one another, about a common geometrical point of rotation and within a predetermined spatial angle; said articulated elements can be fixed in any position relative to one another by clamping; end pieces which are respectively connectable to given ones of said articulated elements; in addition, each of said end pieces is provided with connecting means on a side thereof remote from said articulated elements; rod elements, each of which has a length that is several times greater than its diameter; each of said rod elements is provided with connecting means for cooperating with said connecting means of said end pieces; each of said rod elements comprising two telescoping parts, and clamping means for holding said parts in any position relative to one another.
