Abstract
Abstract A guide chain with supporting link chains including chain links which are connected by crosspieces. To limit the mutual pivot angle, each chain link is provided with slots which extend about a common pivot axis, with engaging studs of an adjacent chain link extending into the slots. In order to facilitate assembly and improve the support capability of the guide chain, each chain link is made as one piece, is provided at one end, on one side, with a disc-shaped plate in which are disposed the slots, and is provided at the other end, on the opposite side, with a cup, on the bottom of which are formed the engaging studs. The diameter of the plate is less than the diameter of the cup, so that the plate of one chain link can be placed into the cup of another chain link.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
224 words
An energy-conveying guide chain for feeding consumable material of all types, via lines, from a stationary connection to a movable consuming device; the lines being disposed in continuous inner spaces within said chain as link-supported therewith, which comprises: a plurality of one-piece chain links, each of which has two ends, with a disk-shaped plate being disposed at one end, on one side of said link, and a cup with a floor being disposed at the other end, on the opposite side of said link; said plate having a central pivot axis, and slots disposed therearound in said plate at one end; said cup having a central pivot axis, and engaging studs disposed therearound and formed in the floor of said cup; each of said plates being provided with a central pivot hole disposed on said pivot axis thereof, and each of said cups being provided with a central pivot journal disposed on said piovt axis thereof; a diameter of said plate being less than a diameter of said cup, so that the plate of one chain link can be placed in the cup of another chain link readily insertable in each other for a snap connection therewith, with the engaging studs of said cup extending into the slots of said plate to limit the angle of pivot of said links relative to one another.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
44 words
A guide chain according to claim 1, in which said cup is provided with a wall, and the diameter of said plate is less than the width of its link by an amount equal to approximately two times the thickness of said cup wall.
Claim 4
Dependent Claim
36 words
A guide chain according to claim 2, in which each link is provided with a groove between said plate and a central portion of said link to accommodate said wall of a cup of another link.
Claim 5
Dependent Claim
22 words
A guide chain according to claim 3, in which the height of said plate is less than the depth of said cup.
Claim 6
Dependent Claim
44 words
A guide chain according to claim 4, in which each of said pivot journals of said cups comprises sections which are separated from one another by slits; that end of each section remote from said bottom of said cup is provided with a groove.
Claim 7
Dependent Claim
43 words
A guide chain according to claim 5, in which each of said plates is provided with a collar which projects radially into said pivot hole, and which engages said grooves of said sections of a pivot journal which extends into said pivot hole.
Claim 8
Dependent Claim
27 words
A guide chain according to claim 4, which includes a sealing member disposed between the plate and cup of two chain links which have been placed together.
Claim 9
Dependent Claim
18 words
