Abstract

A retainer with an axial passage for receiving a format part is disclosed. The retainer includes several clamping tongues facing in the direction of the format part, the clamping tongues being angularly aligned against an outer lateral surface of the format part and being elastically deformable. The format part is held stationary in a first movement direction by the clamping tongues when its outer lateral surface is contacting the clamping tongues and whereby the format part is movable and/or guidable in a second movement direction, the second movement direction being opposite to the first movement direction. Furthermore the retainer includes at least one adjuster, wherein the surface contact between the respective clamping tongues and the format part is released upon actuation and/or upon a defined alignment of the at least one adjuster.

Claims

1. A retainer with an axial passage for receiving a format part comprising:

several clamping tongues facing in the direction of the format part, the clamping tongues being elastically deformable, the clamping tongues angularly aligned against an outer lateral surface of the format part to hold the format part stationary in a first movement direction, the format part being movable in a second movement direction opposite to the first movement direction;

at least one adjuster, contact between the respective clamping tongues and the format part being released upon movement of the adjuster in the second movement direction, the format part as a result being movable in the first movement direction for removal; and

an upper base body and a lower base body, together forming a conical inner space, within which the angularly aligned clamping tongues or the format part are at least partially arranged when the outer lateral surface of the format part is in contact with the clamping tongues, the clamping tongues being part of a one-piece component of the retainer, the one piece component arranged between the upper base body and the lower base body, the upper base body being fixable via bore holes to the lower base body or the one-piece component being fixable via bore holes to the upper base body or to the lower base body, the one piece component being fixable via the bore holes by a screw connection.

2. The retainer as recited in claim 1 wherein the at least one adjuster is slidably mounted along an axis, the axis extending parallel to an outer lateral surface of the format part, and the movement of the adjuster in the second movement direction causes a reversible deformation of the clamping tongues to release the format part.

3. The retainer as recited in claim 1 wherein the one piece component is a clamping disc.

4. The retainer as recited in claim 1 wherein the bore holes of the one-piece component are arranged radially around the axial passage.

5. The retainer as recited in claim 1 wherein the clamping tongues each have two wide side surface areas on opposite sides, tapering in the direction of the axial passage.

6. The retainer as recited in claim 1 wherein the clamping tongues each have a first angular alignment with respect to an axis extending perpendicular to the outer lateral surface of the format part, the clamping tongues each having a second angular alignment with respect to the first axial alignment closer to the axial passage than the first angular alignment.

7. The retainer as recited in claim 6 wherein the first angular alignment is defined by an angle between 0°

and 90°

.

8. The retainer as recited in claim 7 wherein the first angular alignment is defined by an angle of at least about 45°

in a state with no contact between the clamping tongues and the format part.

9. The retainer as recited in claim 1 wherein the format part is supportable or guidable by the at least one adjuster in the state with surface contact of the outer lateral surface of the format part with the clamping tongues and upon movement the at least one adjuster in the second movement direction.

10. The retainer as recited in claim 9 wherein the retainer is designed for receiving a format part with an axis or a bolt.

11. The retainer as recited in claim 10 wherein the retainer is designed for receiving a heating rod in a heating device.

12. The retainer as recited in claim 1 wherein the retainer is designed for receiving a structural component or a working tool.

13. The retainer as recited in claim 1 wherein the retainer is designed for receiving a heating rod in a heating device for preforms.
