Abstract

The present disclosure relates to an adjustable collar for inserting a pipe therein, in particular for positioning and securing a pipe to an apparatus. The present disclosure provides an adjustable collar for inserting a pipe therein, which accepts pipes of any diameter within a predetermined range instead of only accepting pipes of certain standard diameters. Furthermore, pipes can be secured into the adjustable collar without the need for hand tools, adapters, or other accessories.

Claims

1. An adjustable collar for inserting a pipe therein, comprising

a housing with a first open end and a second open end;

at least two sizing clamps, radially movably mounted at said first open end, and having a first end and a second end;

a control ring rotatably mounted at said first open end, and having a first end and a second end; and

one or more clamp guides configured to receive the sizing clamps and and defining an allowed movement range for the sizing clamps;

wherein one of the first and second ends of the control ring and one of the first and second ends of the sizing clamps are in contact with each other, wherein at the contact side of said control ring and sizing clamps, one of the contacting ends of the control ring and sizing clamps is provided with a spiral guide track and the other is provided with cooperative guide followers.

2. The adjustable collar according to claim 1, wherein at the contact side of said control ring and sizing clamps, the contacting end of the control ring is provided with a spiral guide track and the contacting end of the sizing clamps is provided with cooperative guide followers.

3. The adjustable collar according to claim 1, further comprising spacer elements mounted onto control ring to allow for an extended clamping range.

4. The adjustable collar according to claim 1, which comprises an adjustable seal arranged inside the housing.

5. The adjustable collar according to claim 1, wherein the housing comprises a number of seats, arranged stepwise from the first open end of the housing in the direction of the second open end to accommodate pipes of decreasing diameter in the housing.

6. The adjustable collar according to claim 1, which comprises as a locking element for securing and desecuring the clamps in and from a radial position.

7. The adjustable collar according to claim 1, wherein said locking element is a diameter indicating safety lock.

8. The adjustable collar according to claim 1, further comprising a non-return valve inside the housing.

9. The adjustable collar according to claim 1, further comprising a test port integrated into the housing.

10. The adjustable collar according to claim 1, which is an adapter for a flue gas outlet.

11. Computer-readable medium having computer-executable instructions adapted to cause a 3D printer to print the adjustable collar according to claim 1.

12. The adjustable collar according to claim 1, which is mounted to an apparatus.
