Chain link for a link chain and tool magazine with link chain

A tool magazine for a machine tool, the tool magazine comprising:

• a link chain including a plurality of associated chain links for tool transport;
• a drive configured to cause circulating movement of the link chain, each of the chain links including:
• a first side, at which a respective first link portion is located,
• a second side, at which a respective second link portion is located,
• a third side interconnecting the first side and the second side, a respective third link portion being located at the third side, and
• a fourth side interconnecting the first side and the second side,
• wherein the first link portion of one of the chain links is pivotally attached to the second link portion of a first adjacent one of the chain links to provide relative pivoting movement of the one of the chain links relative to the first adjacent one of the chain links about a respective first axis of rotation, and the second link portion of the one of the chain links is pivotally attached to the first link portion of a second adjacent one of the chain links to provide relative pivoting movement of the one of the chain links relative to the second adjacent one of the chain links about a respective second axis of rotation,
• a respective tool receptacle pivotally attached to the respective third link portion of each of the chain links to provide pivoting movement of the respective tool receptacle relative to the corresponding chain link about a respective third axis of rotation, each of the respective tool receptacles having a respective tool receiving portion to receive a tool and each of the received respective tools define a respective longitudinal tool axis;
• and
• a pivot device pivoting the tool receptacle of the one of the chain links in relation to the one of the chain links about the respective third axis of rotation from a transport orientation, in which the respective longitudinal tool axis is parallel to the respective first axis of rotation and the respective second axis of rotation of the one of the chain links, into an exchange orientation, in which the respective longitudinal tool axis is perpendicular to the respective first axis of rotation and the respective second axis of rotation of the one of the chain links, wherein:
• each of the chain links includes a respective first through-opening extending from the respective third side to the respective fourth side,
• each of the tool receptacles includes a respective second through-opening, and
• when a predetermined one of the tool receptacles is in the respective transport orientation, the respective first through-opening and the respective second through-opening of the predetermined one of the tool receptacles border on one another and form a continuous opening through the corresponding chain link and corresponding tool receptacle, and when the predetermined one of the tool receptacles is in the respective exchange orientation, the respective first through-opening and the respective second through-opening do not border one another to form the continuous opening.
