ない煩わしさがあつた。 When attaching a relatively heavy component to a vertical surface using screws, conventionally, to avoid applying large shearing forces to the screws, the screws are placed above the screw fastening point, as shown by A and B in Figure 1. , mounting support plate 101
A rectangular holding hole 102 is formed on the side, and a hook portion 104 that can be hooked into the holding hole 102 is formed on the mounting plate 103 on the component side. By hooking the hook part 104 to the holding hole 102, the weight of the component is reduced between the holding hole 102 and the hook part 104.
This makes it easier to screw in the mounting screw 105. However, as shown in the figure, in the conventional mounting structure of this type, the holding hole 102 has a rectangular shape similar to the end face shape of the hook part 104, and the lower surface of the hook part 104 and the lower end edge of the holding hole 102 are in contact with each other. Since there is considerable play between the hook portion 104 and the holding hole 102 in both the vertical and lateral directions, the screw insertion holes formed on the mounting support plate 101 side and the mounting plate 103 The side screw insertion holes were easily misaligned, and it was troublesome to have to align the screw insertion holes with each other.

である。 FIG. 2 shows, as an application example of the present invention, a latch-type mounting device for a combustion blower 1 in a heating machine to a mounting support plate 2.
In three places, one on the upper side and one on the lower side,
It is attached to the upper front surface of an almost vertical mounting support plate 2, which is also the outer frame of the heater, by means of mounting screws 3. And combustion blower 1
The mounting device of the present invention is applied to two mounting locations on the upper left and right sides. That is,
As shown in FIGS. 3 and 4, the mounting support plate 2 has an inverted triangular retaining hole for latching directly above the screw fastening point with the mounting plate 4 provided on the casing of the combustion blower 1. 5 is passed through the mounting plate 4, and a plate-shaped hook portion 6 which can be hooked into the holding hole 5 is bent at a substantially right angle above the screw fastening portion of the mounting plate 4. Holding hole 5 of mounting support plate 2
is formed on the bottom side which is longer than the width of the plate-like hook portion 6, and a threaded screw insertion hole 7 into which the mounting screw 3 can be screwed is formed directly below the center thereof. In addition, the plate-shaped hook part 6 of the mounting plate 4 on the side of the combustion blower 1 is in the form of a flat plate as shown in the figure, and is wider than the screw fastening point so that the holding hole 5 does not have to be too large. The dimensions have been reduced. Insert this plate-shaped hook part 6 into the holding hole 5 of the mounting support plate 2, and bring the screw fastening part of the mounting plate 4 into close contact with the front surface of the mounting support plate 2, so that the weight of the combustion blower 1 is applied to the mounting plate 4. When this is done, the plate-like hook portion 6 of the mounting plate 4 receives the weight vertically downward and comes into contact with the lower part of the holding hole 5 at two points on the edge of the holding hole 5, forming a chord with respect to the holding hole 5. It stops at . Plate-shaped hook portion 6 for holding hole 5
The most stable manner of latching is one in which the line connecting the two points of the plate-shaped hook part 6 in contact with the holding hole 5 is perpendicular to the direction of the vertically downward force applied to the plate-shaped hook part 6. There is. Based on this most stable relationship between the plate-like hook portion 6 and the holding hole 5, the screw insertion holes 7 and 8 are aligned with the screw fastening locations on the mounting support plate 2 and the screw fastening locations on the mounting plate 4, respectively. (assuming that the center lines coincide). Therefore, if the plate-shaped hook part 6 of the mounting plate 4 is applied to the holding hole 5 of the mounting support plate 2 and weight is applied, the plate-shaped hook part 6 and the holding hole 5 will be in the most stable state. Therefore, the screw insertion holes 7 on the mounting support plate 2 side into which the mounting screws 3 are screwed in and the screw insertion holes 8 on the mounting plate 4 side are aligned or have a relationship close to that. Therefore, screwing in the mounting screw 3 becomes an easy task.
This allows stable installation of the combustion blower 1.

ことができる。 As is clear from the above description of the embodiments, the present invention has a holding hole formed in a mounting support plate provided almost vertically, which has a guiding function in which the opening width dimension in the horizontal direction gradually decreases toward the lower part of the holding hole. It is formed into a triangular shape, into which a plate-shaped hook provided on the mounting plate is loosely fitted, and screws are inserted between the mounting support plate and the mounting plate based on the relationship between the plate-shaped hook and the holding hole. Since this is a latching type mounting structure in which holes are respectively formed, the latching state between the plate-shaped hook part and the holding hole is almost uniquely determined within a certain range when the mounting plate is allowed to hang freely. As a result, the screw insertion holes are automatically aligned with each other. Therefore, the work of screwing screws into the insertion holes can be significantly simplified, and the work of attaching various parts to vertical wall structures can be made more efficient.
