DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory diagram of a wall fixture 1 according to the present invention, in which an upper bracket 2 and a lower bracket 3 are shown on the upper side, and a side view of a water heater 30 with the wall fixture 1 attached on the left side. It shows. First, as shown in FIG. 2, the upper bracket 2 is a rectangular plate having an upper plate 4 and a lower plate 5 that are bent up and down so as to be parallel to each other. 4, a keyhole-shaped suspension through-hole 6 is formed in the center of the lower plate 5, and the lower plate 5 located on the near side is recessed toward the back side, and the bottom surface is flush with the upper plate 4. A horseshoe-shaped recess 7 positioned above and an inverted V-shaped notch 8 whose lower end opens in a tapered shape are formed on the same line as the suspension through-hole 6. Reference numerals 9 and 9 denote screw fixing holes formed on both sides of the lower plate 5, and reference numerals 10 and 10 denote reinforcing V beads.
[0007]
Next, as shown in FIG. 3, the lower bracket 3 is a quadrangular plate that is bent so that the upper plate 11 is on the front and the lower plate 12 is on the reverse side of the upper bracket 2. 11 is bent upward so as to leave a rectangular contact plate 13 at an angle of 90 ° at the center lower end, and screw fixing holes 14 are formed on the left and right of the upper plate 11. 15 and 15 are V beads. The lower plate 12 is provided with rectangular first through holes 16, 16 that are vertically oriented and symmetrically arranged side by side, and substantially between the first through holes 16, 16. An oval second through hole 17 having the same length is formed. Further, on both sides of the lower plate 12, guide pieces 18 and 18 are bent at a right angle on the front side over substantially the entire length of the side edge, and each guide piece 18 is slightly above and below the first through hole 16. An oval guide hole 19 having a short dimension is formed.
[0008]
On the other hand, 20 is a slide plate, and a belt-like plate having a width of about one third of the vertical dimension of the lower plate 12 is folded on both sides so as to be loosely fitted between the guide pieces 18 and 18 of the lower plate 12. The bosses 22 that are formed by bending the bent pieces 21 and 21 and projecting outward from the center of each bent piece 21 are respectively inserted into the guide holes 19 and 19 of the guide pieces 18 and 18 on both sides. By inserting, the slide plate 20 is slidably mounted up and down within a range (L3 in FIG. 3) in which the bosses 22 and 22 are in contact with the upper and lower ends of the guide holes 19 and 19, as indicated by a two-dot chain line. . The slide plate 20 has first screw insertion holes 23 and 23 having a length substantially the same as the width of the first through-hole 16 at a position overlapping with the first through-holes 16 and 16 of the lower plate 12. The second screw insertion holes 24 having substantially the same width as the second through holes 17 are formed at positions overlapping the two through holes 17, so that the first and second screw insertions are possible regardless of the position of the slide plate 20. The holes 23 and 24 are always located in the first and second through holes 16 and 17.
[0009]
As shown in FIG. 1, the wall fixture 1 configured as described above is fixed to the top and bottom of the back cover 31 of the water heater 30 with screws, respectively. The cover 31 is fixed in a state where the bottom surface is in contact. After the upper and lower brackets 2 and 3 are fixed, when the hanging through hole 6 or the notch 8 of the upper bracket 2 is hooked on a mounting screw (not shown) on the wall side, the water heater 30 is suspended from the wall by the upper bracket 2. Be defeated. Next, the lower bracket 3 may be screwed to the wall using the first screw insertion holes 23, 23 or the second screw insertion holes 24 of the slide plate 20, but the slide plate 20 can slide up and down. The screwing position can be freely determined within the slide range of the slide plate 20. That is, when the upper bracket 2 is engaged with the suspension through-hole 6, the slide pitch L1 when the slide plate 20 is in the upper limit position is added to the slide range L3 of the slide plate 20 (L1 + L3). When the mounting pitch can be selected and the upper bracket 2 is engaged with the notch 8, the sliding range L3 of the sliding plate 20 is added to the mounting pitch L2 when the sliding plate 20 is at the upper limit position (L2 + L3). The mounting pitch can be selected.
[0010]
Thus, according to the said form, the slide plate 20 which has the 1st screw insertion hole 23 and the 2nd screw insertion hole 24 in the lower bracket 3 can be slidably provided, and the mounting pitch of the upper and lower brackets 2 and 3 can be adjusted. As a result, the degree of freedom of the mounting pitch is increased, and the length of the water heater 30 may vary greatly when changing from a different manufacturer's water heater as well as different models among the same manufacturer. However, a new water heater 30 can be easily mounted without changing the position of the first mounting screw, and the workability is improved.
Further, since the lower bracket 3 is formed with a contact plate 13 that contacts the bottom surface of the water heater 30 attached to the back cover 31, the contact plate 13 prevents the water heater 30 from tilting left and right. It works to stabilize the installation.
[0011]
The shape of the lower bracket, the specific slide structure of the slide plate, and the like are not limited to those described above. For example, instead of the boss 22 in the slide plate 20, a screw is bent over the guide hole 19 in the lower plate 12. In the lower bracket 3, either the first screw insertion hole 23 or the second screw insertion hole 24 and the corresponding first through hole 16 on the lower plate 12 side and the first screw insertion hole 23 are provided. Either one of the two through holes 17 may be eliminated.
Further, as shown in FIG. 4, the guide piece 25 of the lower plate 12 in the lower bracket 3 is bent inwardly in a U-shape, and the slide plate 20 is formed as a flat plate without a bent portion. It is also possible to adopt a structure that allows sliding by holding. In this case, the lower plate 12 needs a boss 26 and the like for preventing the slide plate 20 from coming off and determining the slide range. Therefore, when the slide plate 20 is fitted between the guide pieces 25, 25, the slide plate 20 may be bent slightly forward and get over the boss 26. The slide plate 20 can also be provided on the opposite surface of the lower plate 12 in any form of FIGS.
[0012]
Furthermore, in the said form, the through-hole 6 for suspension and the notch 8 are provided in the upper bracket 2, and the upper suspension position is also selectable. With this configuration, the degree of freedom of the mounting pitch is further increased by the distance between the hanging through hole 6 and the notch 8, and this is a preferred form, but this hanging through hole can be further increased in the vertical direction, If the degree of freedom by the upper bracket is unnecessary, it is possible to eliminate either the suspension through hole or the cutout. On the other hand, the contact plate 13 is not limited to one at the center, and a plurality of contact plates 13 can be provided at left and right symmetrical positions.
[0013]
【The invention's effect】
According to invention of Claim 1, a lower bracket is attached to the back surface of a water heater, and the lower board extended below the upper board and provided with the long through-hole in the up-down direction, And a slide plate provided so that the front surface of the lower plate can be slid in the vertical direction within the range where the screw insertion hole is located in the through hole. Adjusting the distance from the bracket suspending position to the screw insertion hole increases the degree of freedom in the mounting pitch, allowing different models among the same manufacturer, as well as hot water when replacing from different manufacturers' water heaters. Even if the length of the water heater changes greatly, a new water heater can be easily attached without changing the position of the first mounting screw, and workability is improved.
According to the second aspect of the present invention, in addition to the effect of the first aspect, the abutment plate that abuts the bottom surface of the water heater is extended on the upper plate of the lower bracket, so that the hot water in the attached state is provided. Stabilization of the boiler can be achieved.
According to the third aspect of the invention, in addition to the effect of the first or second aspect, the upper bracket is provided with a plurality of suspension through holes or notches at different heights, so that the mounting pitch can be reduced. The degree of freedom can be further increased.
