DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
In this description, “front” refers to the front side of FIG. 1, “back” refers to the back side, “left” refers to the left side of FIG. 1, and “right” refers to the right side of FIG.
[0007]
The cabinet 1 has a water tank 2 and a gas cooker 3.
Below the water tank 2 and the gas cooker 3 is an article storage space 4.
A piping space 6 (opened rearward and downward) is formed behind a required portion of the back plate 5 of the cabinet 1, and an inspection opening 7 is formed in the back plate 5 so as to face the piping space 6.
The inspection opening 7 is closed by a closing plate 8 having a shape slightly larger than the inspection opening 7 when viewed from the front.
The left and right width of the piping space 6 is arbitrary in a range larger than the left and right width of the inspection opening 7 and smaller than the left and right width of the cabinet 1. Moreover, the vertical length of the piping space 6 is arbitrary in a range larger than the vertical length of the inspection opening 7 and smaller than the vertical length of the cabinet 1.
[0008]
As shown in FIGS. 3 and 4, the lower fixture 11 includes a first member 12 having an engaging portion 13 that engages with an edge portion of the inspection opening 7 and a step portion 14 into which the edge portion of the closing plate 8 is fitted. And a second member 16 having a presser piece 17 that covers the edge of the closing plate 8 fitted to the stepped portion 14 while being connected to the first member 12.
The first member 12 has a fitting recess 19 formed of a groove opened in the left-right direction and downward. The lower opening edges of the fitting recess 19 are close to each other, and the maximum width of the fitting recess 19 is positioned above the lower end of the fitting recess 19. .
In the second member 16, a fitting protrusion 20 having the same or substantially the same cross-sectional shape as that of the fitting recess 19 slidably fitted from the right end portion or the left end portion is formed in the fitting recess 19. Has been.
The second member 16 is fixed to the first member 12 by slidingly fitting the fitting protrusion 20 into the fitting recess 19 from the right end portion or the left end portion of the fitting recess 19. The second member 16 can be detached from the first member 12 by the reverse operation to that described above.
[0009]
The upper fixture 11 in FIG. 1 is obtained by reversing the lower fixture 11 up and down, and the structure is exactly the same.
The first member 12 and the second member 16 are manufactured by cutting an extrusion mold material made of synthetic resin or metal into predetermined dimensions.
[0010]
A water supply pipe 22 having a valve 24 and a hot water supply pipe 23 having a valve 24 are positioned in the piping space 6, and the water supply pipe 22 and the hot water supply pipe 23 are connected to a mixing faucet 25.
[0011]
Method of using the embodiment of the invention
Next, a method of using the embodiment of the invention will be described.
First, a procedure for fixing the closing plate 8 to the back plate 5 and closing the inspection opening 7 with the closing plate 8 will be described.
The engaging portions 13 of the four first members 12 are engaged with the left and right portions of the upper edge portion of the inspection opening 7 and the left and right portions of the lower edge portion of the inspection opening 7. At this time, the stepped portion 14 is directed forward. When the engaging portion 13 is fitted to the edge of the inspection opening 7, the first member 12 is connected to the edge of the inspection opening 7 unless a force equal to or greater than a set value is applied in a direction away from the inspection opening 7. It does not come off from the department.
Thereafter, the closing plate 8 is put on the inspection opening 7 so that the edge of the closing plate 8 is fitted to the stepped portion 14.
Thereafter, the fitting protrusion 20 is slid into the fitting recess 19 so that the presser piece 17 is positioned in front of the closing plate 8.
In this way, the second member 16 can be connected to the first member 12 to fix the closing plate 8 to the back plate 5.
The closing plate 8 can be removed from the back plate 5 by the reverse procedure.
[0012]
[Modifications]
A description will be given below of modifications and the like.
(1) The first member 12 and the second member 16 have large elasticity, and using the elasticity, the fitting protrusion 20 is directed from below the fitting recess 19 to the fitting recess 19 in FIG. The fitting protrusion 20 may be fitted into the fitting recess 19 by forcibly fitting. In this case, the fitting recess 19 does not need to be a groove.
(2) The fitting recess 19 may be formed on one of the first member 12 and the second member 16, and the fitting protrusion 20 may be formed on the other.
(3) The material of the first member 12 and the second member 16 is arbitrary.
