Arranged on the base body at ends in spaced-apart relationship in a conveying direction are coupling sections for swingable connection with a neighboring chain link. Bearings are formed on an upper side of the base body for support of running or guide rollers. A thrust member is connected vertically elastically to an underside of the base body and has an underside provided with at least one recess for formfittingly receiving a coupler of a head piece of the holding adapter for holding the article to be conveyed. ## Claims ### Claim 1 A chain link of a transport chain of a conveyor for conveying an article hanging from a holding adapter, said chain link comprising: a base body having lateral contact surfaces configured to enable friction rollers to be pressed there against for driving the transport chain; coupling sections arranged on the base body at ends in spaced-apart relationship in a conveying direction and configured for swingable connection with a neighboring chain link; bearings formed on an upper side of the base body and configured for support of running or guide rollers; and a thrust member connected vertically elastically to an underside of the base body and having an underside provided with at least one recess for formfittingly receiving a coupler of a head piece of the holding adapter for holding the article to be conveyed. ### Claim 2 (depends on 1) The chain link of claim 1, wherein the at least one recess of the thrust member has in the conveying direction a trailing edge which is oriented transversely to the conveying direction and aligned at an obtuse angle in relation to the underside of the thrust member which underside is oriented in parallel relation to the conveying direction. ### Claim 3 (depends on 1) The chain link of claim 1, further comprising a spring element configured to connect the thrust member with the base body. ### Claim 4 (depends on 3) The chain link of claim 3, wherein the spring element is configured in the form of a spring leaf configured to extend at a slant for interconnecting the base body with the thrust member. ### Claim 5 (depends on 4) The chain link of claim 4, wherein the spring element extends in relation to the base body and the thrust member at an angle between 5° and 30°. ### Claim 6 (depends on 1) The chain link of claim 1, constructed in one piece. ### Claim 7 A transport chain of a conveyor for conveying an article hanging from a holding adapter, said transport chain comprising a plurality of chain Links swingably connected to one another, each said chain link including a base body having lateral contact surfaces configured to enable friction rollers to be pressed there against for driving the transport chain, coupling sections arranged on the base body at ends in spaced-apart relationship in a conveying direction and configured for swingable connection with a neighboring chain link, bearings formed on an upper side of the base body and configured for support of running or guide rollers and a thrust member connected vertically elastically to an underside of the base body and having an underside provided with at least one recess for formfittingly receiving a coupler of a head piece of the holding adapter for holding the article to be conveyed. ### Claim 8 (depends on 7) The transport chain of claim 7, wherein the at least one recess of the thrust member has in the conveying direction a trailing edge which is oriented transversely to the conveying direction and aligned at an obtuse angle in relation to the underside of the thrust member which underside is oriented in parallel relation to the conveying direction. ### Claim 9 (depends on 7) The transport chain of claim 7, wherein the chain link has a spring element configured to connect the thrust member with the base body. ### Claim 10 (depends on 9) The transport chain of claim 9, wherein the spring element is configured in the form of a spring leaf configured to extend at a slant for interconnecting the base body with the thrust member. ### Claim 11 (depends on 10) The transport chain of claim 10, wherein the spring element extends in relation to the base body and the thrust member at an angle between 5° and 30°. ### Claim 12 (depends on 7) The transport chain of claim 7, wherein the chain link is made in one piece. ### Claim 13 (depends on 7) The transport chain of claim 7, wherein the thrust member has overlap portions on spaced-apart ends in the conveying direction for connection with a thrust member of an adjacent chain link. ### Claim 14 A conveyor for conveying a hanging article, comprising: a rail profile; a transport chain having a plurality of chain links and movable in the rail profile in a conveying direction, each said chain link including a base body having lateral contact surfaces configured to enable friction rollers to be pressed there against for driving the transport chain, coupling sections arranged on the base body at ends in spaced-apart relationship in a conveying direction and configured for swingable connection with a neighboring chain link, and a thrust member formed an underside of the base body and having an underside provided with at least one recess; and a holding adapter configured to hold the article to be conveyed and having a head piece which is rollingly supported in the rail profile and configured for coupling with the thrust member. ### Claim 15 (depends on 14) The conveyor of claim 14, wherein the at least one recess of the thrust member has in the conveying direction a trailing edge which is oriented transversely to the conveying direction and aligned at an obtuse angle in relation to the underside of the thrust member which underside is oriented in parallel relation to the conveying direction. ### Claim 16 (depends on 14) The conveyor of claim 14, wherein the chain link has a spring element configured to connect the thrust member with the base body. ### Claim 17 (depends on 16) The conveyor of claim 16, wherein the spring element is configured in the form of a spring leaf configured to extend at a slant for interconnecting the base body with the thrust member. ### Claim 18 (depends on 17) The conveyor of claim 17, wherein the spring element extends in relation to the base body and the thrust member at an angle between 5° and 30°. ### Claim 19 (depends on 14) The conveyor of claim 14, wherein the chain link is made in one piece. ### Claim 20 (depends on 14) The conveyor of claim 14, wherein the thrust member has overlap portions on spaced-apart ends in the conveying direction for connection with a thrust member of an adjacent chain link. ### Claim 21 (depends on 14) The conveyor of claim 14, further comprising running rollers supported by the head piece of the holding adapter and configured to roll in the rail profile, said head piece having a coupler configured to extend beyond the running rollers and received in the at least one recess by a formfit when engaged with the thrust member, said formfit between the thrust member and the coupler of the holding adapter being configured to resiliently deflect the thrust member in a direction of the base body of the chain link when the coupler of the holding adapter exerts a predefined force impact upon the thrust member, wherein the formfit to the holding adapter is releasable. ### Claim 22 (depends on 20) The conveyor of claim 20, wherein the overlap portions of the thrust member define a leading overlap portion and a trailing overlap portion, said leading overlap portion of the thrust member engaging underneath a trailing overlap portion of the thrust member of the adjacent chain link. ### Claim 23 (depends on 14) The conveyor of claim 14, wherein the holding adapter has a mount for an identification piece.
