Abstract

A cutting guide serves to adjust a length of an exhaust tube introduced in an exhaust pipe so as to adapt to combination of the exhaust pipe communicating from the inside to the outside of a building with an exhaust terminal attached to an end portion of the exhaust pipe on an outdoor side. The cutting guide has a reference site for alignment with an exhaust pipe unit including the exhaust pipe, and has an indication of a cutting position of the exhaust tube for adjusting a length of the exhaust tube protruding from the end portion of the exhaust pipe portion on the outdoor side to a length adapted to a type of the exhaust terminal.

First claim

What is claimed is:

1. A cutting guide for adjusting a length of an exhaust tube introduced in an exhaust pipe so as to adapt to combination of said exhaust pipe communicating from inside to outside of a building with an exhaust terminal attached to an end portion of said exhaust pipe on an outdoor side, comprising:
a reference site for alignment with an exhaust pipe unit including said exhaust pipe; and
a first indication of a cutting position of said exhaust tube for adjusting a length of said exhaust tube protruding from an end portion of said exhaust pipe unit on the outdoor side to a length adapted to a type of said exhaust terminal, wherein
the cutting guide has a second indication of at least one of an illustration, a character, and a graphic representation of the cutting guide, the exhaust pipe unit, and the exhaust tube, showing a use situation of the cutting guide in which the reference site of the cutting guide is aligned with an upper surface of the end portion of the exhaust pipe unit on the outdoor side and another site other than the reference site of the cutting guide is aligned with an outer circumferential surface of the exhaust tube protruding from the end portion of the exhaust pipe unit on the outdoor side,
said first indication indicates the cutting position in accordance with the type of said exhaust terminal,
said cutting position in accordance with the type of said exhaust terminal is indicated with a graphic representation representing the exhaust terminal and an indication indicating the cutting position,
the graphic representation representing the exhaust terminal is arranged at a position corresponding to a position at which the indication indicating the cutting position of the exhaust tube adapted to the exhaust terminal is arranged, and
the cutting guide does not have a through hole.

2. The cutting guide according to claim 1 , wherein
said graphic representation representing the exhaust terminal is at least any one of a photograph and an illustration of said exhaust terminal.

3. The cutting guide according to claim 1 , wherein
said cutting guide is a rectangular sheet member and has one side for alignment with the outer circumferential surface of said exhaust tube protruding from said end portion of said exhaust pipe unit on the outdoor side and another side for alignment with the upper surface of said end portion of said exhaust pipe unit on said outdoor side, and
said another side intersects with said one side and implements said reference site.

4. The cutting guide according to claim 3 , wherein
said one side has a shape fitting to a shape of the outer circumferential surface of said exhaust tube.

5. The cutting guide according to claim 3 , wherein
said one side has a stepped shape having a plurality of steps and at least one step of said plurality of steps corresponds to illustrated said cutting position.

6. The cutting guide according to claim 1 , wherein
said cutting guide is a cylindrical member and constructed to be able to surround from an outer circumferential side, a part of the outer circumferential surface of said exhaust tube protruding from said end portion of said exhaust pipe unit on the outdoor side.

7. The cutting guide according to claim 1 , wherein
said cutting guide has a sheet member having a surface where said cutting position is shown and an adhesive material formed on a surface opposite to the surface of said sheet member where said cutting position is shown.

8. The cutting guide according to claim 1 , wherein
a surface of said cutting guide where at least said cutting position is shown is waterproofed.
