Hook holder for a machine tool

1. A holding apparatus for being detachably attached to a machine tool housing of a machine tool and for receiving a hook for hanging the machine tool from the hook, the holding apparatus comprising:

a fastening portion for fastening the holding apparatus to the machine tool housing;

a securing device for securing the holding apparatus on the machine tool housing; and

a receiving portion having an opening and being intended for receiving and rotatably supporting an insertion portion of the hook, the receiving portion defining an axial direction;

the fastening portion having a first interlocking connector designed to engage with first mating interlocking connector provided on the machine tool housing, an interlocking connection between the first interlocking connector and the first mating interlocking connector allowing movement of the holding apparatus in a sliding direction and preventing movement perpendicular to the sliding direction, the securing device being movable between an open position and a locked position, the securing device being designed to prevent the holding apparatus from moving in the sliding direction in the locked position and to allow movement in the sliding direction in the open position.

2. The holding apparatus as recited in claim 1 wherein the first interlocking connector and the first mating interlocking connector form a dovetail joint.

3. The holding apparatus as recited in claim 1 wherein the fastening portion includes a through-opening and the securing device includes an actuator having a first end and a first end portion extending from the first end and a second end and a second end portion extending from the second end, the first end portion being rigidly couplable to the holding apparatus and the second end portion being designed to project into the through-opening in the fastening portion, the second end protruding beyond the fastening portion when the securing device is in the locked position and being arranged within the through-opening in the fastening portion when the securing device is in the open position.

4. The holding apparatus as recited in claim 3 wherein the fastening portion includes a coupling part having the first interlocking connector and an arm projecting from the coupling part, the first end portion being rigidly connectable to the arm.

5. A holding system for holding a machine tool, the holding system comprising:

the holding apparatus as recited in claim 1 and the hook having the insertion portion, the insertion portion of the hook being introducible into the receiving portion of the holding apparatus.

6. The holding system as recited in claim 5 further comprising a first latch interacting with the receiving portion of the holding apparatus and intended for defining a rotational position of the hook relative to the holding apparatus, the first latch being couplable to the insertion portion of the hook for rotation therewith.

7. The holding system as recited in claim 6 wherein the first latch includes at least one spring arrangement and the receiving portion includes at least one depression, the at least one spring arrangement being designed to engage with the at least one depression in the receiving portion.

8. The holding system as recited in claim 5 further comprising at least one second latch interacting with the insertion portion of the hook and including a second interlocking connector for defining a rotational position of the hook relative to the holding apparatus and the receiving portion of the holding apparatus having at least one depression extending axially along an inner surface of the opening in the receiving portion, and into which the at least one second latch can be introduced such that the second interlocking connector of the at least one second latch can be brought into engagement with second mating interlocking connector provided on an outer face of the insertion portion of the hook introduced in the receiving portion.

9. The holding system as recited in claim 8 wherein the at least one second latch has a first leg and a second leg interconnected at one of their ends via a connecting portion, a free end of the first leg opposite the connecting portion including the second interlocking connector.

10. A machine tool comprising: the holding system as recited in claim 5 .
