Abstract
Abstract A guide chain for guiding energy lines from a stationary connection to a movable consuming device is comprised of a plurality of chain members being pivotably connected to one another. Each of the chain members is comprised of two side portions arranged at a distance parallel to one another. Two transverse elements connect the two side portions with one another. In order to open the guide chain at its upper side on either side of the side portions for providing access to the energy line channel, the two side portions are provided with a pivot joint which is comprised of a lug element extending in the longitudinal direction of the side portion and a holding member which is detachably connected to the lug element, the transverse element being connected to the two holding members.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
179 words
A guide chain for guiding energy lines from a stationary connection to a movable consuming device, said guide chain comprising: a plurality of chain members being pivotably connected to one another, each one of said chain members being comprised of: two side portions arranged at a distance parallel to one another; two transverse elements connecting said side portions with one another; at least two pivot joints, a first one of said pivot joints fastened to a first one of said side portions and a second one of said pivot joints fastened to a second one of said side portions, for pivotably connecting at least one of said transverse elements to said side portions, said pivot joints each comprising a lug element, extending in a longitudinal direction of said side portions and forming a pivoting axis of said pivot joint, and a holding member connected in a detachable manner to said lug element, said holding member having a U-shaped cutout with undercuts for receiving said transverse element, said transverse element being inserted into said U-shaped cutout with a rotating movement.
Claim 2
Dependent Claim
179 words
A guide chain for guiding energy lines from a stationary connection to a movable consuming device, said guide chain comprising: a plurality of chain members being pivotably connected to one another, each one of said chain members being comprised of: two side portions arranged at a distance parallel to one another; two transverse elements connecting said side portions with one another; at least two pivot joints, a first one of said pivot joints fastened to a first one of said side portions and a second one of said pivot joints fastened to a second one of said side portions, for pivotably connecting at least one of said transverse elements to said side portions, said pivot joints each comprising a lug element, extending in a longitudinal direction of said side portions and forming a pivoting axis of said pivot joint, and a holding member connected in a detachable manner to said lug element, said holding member having a U-shaped cutout with undercuts for receiving said transverse element, said transverse element being inserted into said U-shaped cutout with a rotating movement.
Claim 3
Dependent Claim
22 words
