  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a use state of a tool for disconnecting a dual air supply and exhaust cylinder according to the embodiment of the present invention (hereinafter sometimes simply referred to as a "tool for disconnecting connection").
The gas water heater is shown as an example of a predetermined | prescribed apparatus. The dual supply and exhaust cylinder 20 is overlapped and connected to the dual supply and exhaust unit 10 of the gas water heater G.
A non-slip member 30 is attached to the double supply and exhaust cylinder 20, and a disconnection tool 40 is set there.

[Tool for Disconnection 40]
Here, the disconnection tool 40 is made of iron, but the material is optional as long as it achieves the function of the present invention.

As shown in FIG. 2, the dual supply and exhaust cylinder 20 on which the anti-slip member 30 is mounted is fitted to the ring portion 41 of the disconnection tool 40, and the two handle portions 61 and 62 are formed. The connection between the dual air supply and discharge unit 10 and the dual air supply and exhaust cylinder 20 is released by holding, rotating, and pulling with both hands.
The internal diameter of the ring portion 41 in the closed state is made about 3 mm larger than the outer peripheral diameter of the dual supply and exhaust cylinder 20, and a gap is provided, whereby the dual supply and exhaust cylinder on which the non-slip member 30 is mounted It is supposed to fit 20.
A non-slip uneven portion 42 is provided on the inner surface side of the ring portion 41 (the surface in contact with the non-slip member 30 or the like). The uneven portion may be easily realized by an adhesive applied and solidified in a grid shape.

As shown in FIGS. 3 and 4, the ring portion 41 of the disconnection tool 40 is configured to be able to transition between the open state and the closed state by the two ring forming members 43 and 44 connected by the hinge 45. It is done.
In order to fix the closed state of the two ring forming members 43 and 44 of the ring portion 41, the disconnecting tool 40 is provided with one fastener portion 50 (here, as an example, a screw mechanism). There is. The tightening degree of the fastener portion 50 can be adjusted so that the double supply and exhaust cylinder 20 pinched by the two ring forming members 43 and 44 of the ring portion 41 is not deformed too much.
On the outer surface side of the ring portion 41, two attachment portions 46 and 47 (here, by way of example, screw grooves) that make the two handle portions 61 and 62 detachable are opposed in the radial direction of the ring portion 41 It is provided in the position. Since two are provided at opposite positions in the radial direction of the ring portion 41, the force of the operator can be transmitted effectively and efficiently. In addition, one or more mounting portions are provided, and the handle portion 61 and the like can be mounted at a more suitable position when working (the dual supply and exhaust cylinder 20 is installed in the vicinity of a wall surface etc. Even in a situation where the ring portion 41 can not be rotated by hitting the wall portion because of a long length of time, etc., once the handle portion that collides with the wall portion is removed, the wall portion does not become an obstacle The handle portion may be attached to the attachment portion again, etc.) or the number of handle portions may be increased according to the number of attachment portions.

Here, the rod-like base end portions of the handle portions 61 and 62 are threaded so as to be detachable from the attachment portions 46 and 47. For example, although it is set as rod shape, a shape is arbitrary. Since there are two handle portions, the operator can effectively and efficiently apply the force necessary to release the connection state that the operator holds, rotates, and pulls the two handle portions with both hands. . In addition, the dual supply and exhaust cylinder 20 may be installed at a narrow place where it is difficult to work, and it is possible to cope with the case where the worker can not exert 100% of the arm force by using the disconnection tool 40. .
Since the handle portions 61 and 62 are detachable from the attachment portions 46 and 47, the double feed / exhaust cylinder 20 is installed in the vicinity of a wall surface or the like, and the handle portions 61 and 62 are long and hit the wall portions to ring Even in a situation where the portion 41 can not be rotated, the ring portion 41 is rotated slightly by temporarily removing one handle portion that collides with the wall portion, and the attachment portion 46 of the ring portion 41 is attached. , 47 is a position where the wall portion is not an obstacle, and it is possible to cope with mounting the handle portion again.

[Anti-slip member 30]
As shown in FIGS. 5 and 6, a non-slip member 30 (here, a non-slip net as an example) is attached to the dual supply and exhaust cylinder 20. The dual supply and exhaust cylinder 20 is made of stainless steel or the like, and as it is, the connection release tool 40 is easily slippery. The non-slip member 30 may be wound twice around the outer periphery of the dual supply / discharge cylinder 20. In addition, the non-slip member 30 has an appropriate elasticity and also functions to prevent the deformation of the double supply / discharge cylinder 20. A commercially available non-slip mat (thickness 3 mm, made of vinyl chloride) or the like may be cut out and used as the non-slip member 30 by a necessary amount.

  Next, with reference to FIG. 7, the flow of the method for disconnecting the dual supply and exhaust stack according to the present embodiment will be described in detail.

  First, the non-slip member 30 is attached to the double feed / exhaust cylinder 20 which is overlapped and connected to the double feed / exhaust unit 10 of the gas water heater G as a predetermined device (step S701).

  Next, a non-slip uneven portion 42 is provided on the inner surface side which can be transitioned between the open state and the closed state by the two ring forming members 43 and 44 joined by the hinge 45 of the disconnection tool 40 The connection release tool 40 so that the dual supply and exhaust cylinder 20 (the anti-slip member 30 is attached) is fitted to the ring portion 41 in a state where the two ring forming members 43 and 44 of the ring portion 41 are closed. (Step S702).

  Next, the dual supply and exhaust cylinder 20 is tightened so as to be fitted to the ring portion 41 by the fastener portion 50 of the disconnection tool 40 to fix the two ring forming members 43 and 44 in a closed state ( Step S703).

  Next, two mounting portions 46 and 47 for making the handle portions 61 and 62 detachable on the outer surface side are attached at least to two ring portions 41 provided at positions opposite in the radial direction of the ring portion 41 The two handle portions 61 and 62 are attached to the portions 46 and 47, respectively (step S704). Note that step S704 may be omitted, that is, two handle portions 61 and 62 may be attached to two attachment portions 46 and 47 in advance.

  Then, the operator holds the two handle portions 61 and 62 with one hand using both hands, and rotates the whole of the connection release tool 40 in the circumferential direction of the ring portion 41, or the rotation surface of the rotation Two of the gas water heater G by pulling in the vertical direction (vertical direction in FIG. 1) (which naturally includes an operation such that rotation in the circumferential direction and pulling in the direction perpendicular to the plane of rotation are simultaneously performed). The state where the heavy feed and exhaust unit 10 and the dual feed and exhaust cylinder 20 are overlapped and connected is released (step S 705). The dual supply and exhaust cylinder 20 may be configured to be slidable and expandable.

  According to the above-described embodiment, even if the worker is not a particularly strong worker, no one needs a large force and does not destroy or break the dual supply and exhaust cylinder. The connection state of the dual supply and exhaust cylinder 20 can be reliably released with the original shape of the dual supply and exhaust cylinder 20.

[Modification]
The disconnection tool 40 not only releases the state in which the dual supply and exhaust unit 10 and the dual supply and exhaust cylinder 20 are overlapped and connected, but conversely, the dual supply and exhaust unit 10 and the dual supply and discharge. It can also be used when connecting the cylinder 20 in an overlapping manner.

  The embodiments described above are preferred embodiments of the present invention, and various modifications can be made without departing from the scope of the present invention. For example, it is applicable not only to a double feed and exhaust pipe but also to a single exhaust pipe and the like of a chimney of a stove and a boiler or the like, and a connection point such as a single exhaust pipe type gas water heater.
