Next, the structure of the wall fixing metal fixture which fixes the housing | casing and wall of the 1st Embodiment of this invention is demonstrated based on drawing.
FIG. 1 is a side view of the housing and the wall. Reference numeral 1 denotes a substantially rectangular parallelepiped housing, for example, a housing of a hot water storage type hot water heater provided inside with a hot water storage tank for storing hot water (not shown). Reference numeral 2 denotes a leg portion that supports the casing 1 of the hot water storage type water heater and is fixed to the installation surface by an anchor bolt (not shown). Reference numeral 3 denotes a wall of a house or the like on which the casing 1 of the hot water storage type water heater is installed. Reference numeral 4 denotes an L-shaped wall fixing bracket for fixing the side surface or top surface of the casing 1 of the hot water storage type water heater and the wall 3, and reference numeral 5 denotes a casing 1 of the hot water storage type water heater and the L-shaped wall fixing bracket 4. It is a fixing tool such as a screw.

As shown in FIGS. 2 and 3, the wall fixing bracket 4 is an L-shape having a long piece 4 a fixed to the casing 1 of the hot water storage hot water supply device and a short other piece 4 b fixed to the wall 3. In the long piece 4a of the wall-fixing metal fitting, two parallel long holes 6 are opened along the longitudinal direction, and a plurality of hole portions 7 for fixing the wall are opened in the short other piece 4b. . Further, in the direction orthogonal to the longitudinal direction of the long hole 6, a plurality of groove portions 8 that are continuously opened from the long hole 6 are provided symmetrically. Here, a total of six groove portions 8 are provided at three positions on the upper and lower sides from the longitudinal center of the long hole 6. The width of the groove 8 is slightly larger than the shaft diameter of the fixture 5 and smaller than the screw head diameter, and is approximately the same as the width of the elongated hole 6. The depth is about 6 to 1.5 times.

  When the housing is installed, as shown in FIG. 4, the short other piece 4 b between the wall 3 of the house and the wall fixing metal 4 is fixed with a screw or the like through the hole 7 for fixing the wall. The long piece 4 a and the housing 1 of the hot water storage type hot water heater are fixed by the fixture 5 through the long hole 6. At that time, the installation position of the case 1 of the hot water storage type hot water heater can be appropriately moved by a distance corresponding to the dimension range of the long hole 6, so that the distance from the wall 3 differs depending on the installation location. Can be securely fixed.

  Further, when the strength of the shaking exceeds the fastening force of the fixture due to a large shaking such as an earthquake, the housing 1 of the hot water storage type water heater slides within the range of the dimension of the long hole 6. However, since the long hole 6 has a shape having the groove portion 8, as shown in FIG. 5, the fixing tool 5 is caught by the groove portion 8 when sliding, and the casing 1 of the hot water storage type water heater slides to the end of the long hole 6. Can be suppressed.

  In this way, when the fixture 5 is caught in the groove portion 8, the housing 1 of the hot water storage type water heater is prevented from being greatly inclined, and the leg portion 2 is damaged due to a load applied to the leg portion 2 of the housing 1. And deformation can be prevented.

  Next, 2nd Embodiment which changed the position of the groove part 8 of the wall fixing metal fitting 4 is described based on FIG. Here, the same components as those in the first embodiment are designated by the same reference numerals, and the description thereof is omitted.

  Here, as shown in FIG. 5, the upper slot 6a, the lower slot 6b, a plurality of vertically symmetrical grooves provided in the upper slot 6a at equal intervals are formed 8a, and the lower slot 6b. The vertically symmetric groove portions provided at equal intervals are referred to as 8b, the vertical center line of the upper groove portion 8a is referred to as A, and the vertical center line of the lower groove portion 8b is referred to as B.

  And the groove part 8a and the groove part 8b are provided in the position shifted by the distance C of the wall fixing bracket 4 between the center line A and the center line B. This distance C indicates that when the casing 1 is tilted from 1 ° to several degrees in the longitudinal direction of the wall fixing bracket 4, the two fixing tools 5 screwed to the casing 1 rotate around the tilt fulcrum. In this case, it is determined as appropriate based on the horizontal distance between the upper and lower fixtures 5.

  As described above, since the groove 8a and the groove 8b are provided by being shifted by the distance C, the fixture 5 can easily enter the groove 8 even when the housing 1 is tilted during a large shake such as an earthquake. As a result, it is possible to prevent the housing 1 from being greatly inclined and to prevent the leg 2 from being damaged or deformed due to a load on the leg 2 of the housing 1.

  In the first and second embodiments, the shape of the groove portion 8 has been described as a U-shape. However, the shape is not limited to this, and may be, for example, a V-shape or a square shape.

  Next, 3rd Embodiment which changed the shape of the groove part 8 of the wall fixing metal fitting 4 is described based on FIG. Here, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.

  The groove portion 8 of this third embodiment has a narrow entrance 9 and a long groove 10 that extends symmetrically in the longitudinal direction of the long piece 4a of the wall fixing bracket 4 at a position continuously recessed from the entrance 9. It is what you are doing.

  The shape of the entrance 9 is tapered, and the opening near the elongated hole 6 is wide and narrows toward the back. The width of the opening portion of the entrance 9 is smaller than the shaft diameter screw head diameter of the fixture 5 and larger than the width of the long hole 6. The width of the portion close to the long groove 10 is slightly larger than the shaft diameter of the fixture 5 and smaller than the screw head diameter and is approximately the same as the width of the long hole 6. Thereby, when the fixing tool 5 slides and enters the groove portion 8, it is possible to make a shape that is easy to enter and is not easily removed.

  Also, the width of the long groove 10 in the short direction is slightly larger than the shaft diameter of the fixture 5 and smaller than the screw head diameter and is approximately the same as the width of the long hole 6 and the length of the long groove 10 in the long direction. Is about 1.5 to 3 times the shaft diameter of the fixture 5.

  As described above, since the groove portion 8 is configured to be provided with the entrance 9 and the long groove 10 in the back thereof, the fixing tool 5 that is stuck in the long groove 10 has a characteristic that it is difficult to go out. When the slide slides into the long groove 10 from the entrance 9, the swing width can be suppressed by the distance of the long groove 10, and the fixture 5 is easy because the exit portion of the long groove 10 is narrow against vertical swing. Can be prevented. Moreover, it can suppress that the housing | casing 1 inclines largely and can prevent the damage, deformation | transformation, etc. of the leg 2 which occur when the leg 2 of the housing | casing 1 is loaded.

  In addition, this invention is not limited to 3rd Embodiment, It does not prevent changing in the range which does not change a summary, For example, the shape of the groove part 8 is a curved long groove shape, or a groove | channel The shape is not symmetrical and extends only to one side, or the tapered portion of the entrance 9 may be reversely tapered or non-tapered.

In the first to third embodiments, for example, the case of this time is a hot water storage type hot water heater, but an electric water heater or a hot water boiler having a top surface and a side surface may be used. .
