Chain link having a multi-axis link joint
A chain link for an energy drag chain that guides conduits, tubes or the like between a stationary point of connection and a mobile point of connection. The chain link includes a cross piece and two spaced-apart link plates. The cross piece is connected to at least one link plate in an articulated manner and the connection between the cross piece and link plate can be a multi-axis connection.
1. A chain link for an energy drag chain that extends between a stationary connection point and a mobile connection point, the chain link comprising:
a cross piece having a substantially spherical head; and
two link plates arranged at a distance from one another, and at least one of the link plates includes a socket for receiving the substantially spherical head to join the cross piece and the link plate at a multi-axial articulated joint without a threaded connection portion.
2. The chain link according to claim 1 , wherein the cross piece comprises:
a first end region, and the first end region includes the substantially spherical head arranged on an axis that intersects a longitudinal axis of the cross piece, and the substantially spherical head is at least a portion of the multi-axial articulated joint.
3. The chain link according to claim 1 , wherein the socket is at least a portion of the multi-axial articulated joint.
4. The chain link according to claim 1 , wherein at least one link plate is made at least partially from plastic.
5. The chain link according to claim 1 , wherein the cross piece is disposed to form a cover over a space between the two link plates.
6. A chain link for an energy drag chain that extends between a stationary connection point and a mobile connection point, the chain link comprising:
a cross piece having a socket; and
two link plates arranged at a distance from one another, and at least one of the link plates includes a substantially spherical head for engaging the socket to join the cross piece and the link plate at a multi-axial articulated joint.
7. The chain link according to claim 6 , wherein the cross piece comprises:
an end region defining the socket that is at least a portion of the multi-axial articulated joint.
8. The chain link according to claim 6 , wherein the cross piece comprises:
a first end region, and the first end region includes the socket to define an axis arranged substantially parallel to a longitudinal axis of the cross piece, and the socket is at least a portion of the multi-axial articulated joint.
9. The chain link according to claim 6 , wherein the cross piece comprises:
an end region defining the socket, and the socket is substantially spherical to define at least a portion of the multi-axial articulated joint.
