Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a support device for a fan for wall hangings.

(B) Conventional Technology A conventional wall-mounted fan is shown in Japanese Utility Model Publication No. 57-6797 (F04D29 / 00) (see FIG. 7).

That is, the opening 53 is provided in the bottom plate 52 of the stand 51 of the wall-mounted fan, and the beam 55 is screwed to the support column 54 of the stand 51.
Tongue piece 56 that fits with the opening 53 and a recess that fits with the beam 55
A mounting base 58 having 57 is fixed to a wall surface 59, and the wall-mounted fan is supported by fitting the opening 53 of the bottom plate 52 with the tongue piece 56 and the beam 55 with the recess 57.

(C) Problems to be solved by the invention In the conventional example, since the beam 55 and the strut 54 are fixed at only one point, there is a possibility that the beam 55 may come off the strut 54 during use. In addition, since the fan for wall hangings and the mounting base are supported only by fitting from above, there is a risk that the fan for wall hangings will fall off from the wall surface when the force from below is applied. .

The present invention relates to an improvement of a supporting device for a wall-mounted fan, and solves such a problem.

(D) Means for Solving the Problems A support device for a fan for wall hangings according to the present invention is a composite device that supports a mounting plate that is fixed to a wall surface and has a screw hole at an upper end, and a drive unit that includes a motor and a fan. A stand made of resin, a bottom plate that closes the bottom surface of the stand, and a bottom plate that is provided on the bottom plate and is inserted between the upper end and the wall surface of the mounting plate from above when the stand is mounted to the mounting plate. And a support rib that is integrally formed with the stand, is applied with the bottom plate, and abuts against the upper end of the mounting plate from above when the insertion part is completely inserted, and the support rib on the stand. A screw boss that is integrally formed with the support rib and that matches the screw hole when the supporting rib abuts, and that is screwed into the screw hole to fix the screw boss to the mounting plate. It is equipped with a screw.

(E) Action That is, since the stand is screwed to the mounting plate and the screw boss mutually reinforces the supporting ribs, the force from above, below, left and right is sufficiently resisted.

Further, when the stand is inserted into the mounting plate from above, the support ribs come into contact with each other to match the screw hole with the screw boss.

Moreover, since the bottom plate can be applied to the support ribs, the bottom plate can be firmly fixed to the stand.

(F) Embodiment An embodiment of the present invention will be described with reference to the drawings.

1 is a drive unit, a motor 2, a fan 3, and a protective guard 4
It consists of and. Reference numeral 5 denotes a synthetic resin stand, which is composed of a box-shaped base 6 having an open bottom surface and a pillar 7 projecting from the base 6, and the pillar 7 supports the drive unit 1. Reference numeral 8 denotes a metal bottom plate that closes the bottom surface of the base 6, and a boss 9 formed inside the base 6.
It is fixed with a small screw 10 ... 11 and 11 are the bottom plates 8
Fitting holes 12 and 12 provided under the fitting holes 11 and 12 are buffer members made of an elastic goss material fitted into the fitting holes 11 from the rear surface side of the bottom plate 8 and slightly smaller than the fitting holes 11 and 11. Large shaft 1
2a and a head portion 12b having a diameter larger than that of the shaft portion 12a. Therefore, the cushioning members 12, 12 are fitted in the fitting holes 11, 11 while the shaft portion 12a thereof is elastically deformed, and the head portion 12b is brought into contact with the bottom plate 8 to move inwardly into the base 6. It will prevent it from slipping out. Reference numeral 13 is an air flow rate changeover switch arranged inside the base 6, 14 is a switch operating knob arranged on the upper surface of the base 6, and 15 is a swinging selection arranged on the base of the column 7. It is a switch.

Reference numeral 16 is a shield plate having an insulating property, and has mounting holes 17, 17 and 18 at positions that are aligned with the fitting holes 11 and 11 and one of the bosses 9 ... . Among the mounting holes, the one 17 that matches the fitting holes 11 and 11 has the same diameter as the fitting holes 11 and 11 that matches the boss 9
The diameter is larger than the boss 9.

That is, the shielding plate 16 is a cushioning member attached to the bottom plate 8.
By fitting the shaft portions 12a of 12 and 12 into the mounting holes 17 and 17, the shaft portions 12a are attached to the bottom plate 8 and are located between the changeover switch 13 and the bottom plate 8, and the contacts 13a of the switch 13 are provided. Are prevented from coming into contact with the bottom plate 8 to cause a short circuit.

Reference numeral 19 denotes a metal mounting plate screwed to the wall surface 20, and the upper end portion 19a is bent in an inverted L shape so that a gap 21 is formed between the upper end portion 19a and the wall surface. . 22 is a screw hole formed in the upper end portion 19a.

Now, reference numeral 23 is an insertion portion formed by bending the upper end portion of the bottom plate 8, and is inserted into the gap 21 from above when the stand 5 is attached to the attachment plate 19. Reference numeral 24 is a support rib integrally formed on the inner upper part of the base 6, and has an end face 24a to which the bottom plate 8 is applied and an abutting part 24b abutting on the upper end 19a from above. There is. twenty five
Is a screw boss integrally formed inside the base 6 so as to match the screw hole 22 when the contact portion 24b contacts the upper end 19a, and is continuous with the support rib 24. There is. 26 is a screw boss 25 that is screwed into the screw hole 22
It is a screw to fix to 19.

In order to attach the stand 5 to the attachment plate 19, first, the insertion portion 23 is inserted into the gap 21 from above. Then, the contact portion 24b of the support rib 24 contacts the upper end portion 19a, and the screw hole 22 and the screw boss 25 are aligned with each other, so that both are fixed by the screw 26.

In this way, the upper part of the stand 5 is fixed to the wall surface, and the lower part is supported by abutting against the wall surface via the heads of the cushioning members 12, 12.

(G) Effect of the Invention In the configuration of the supporting device for the fan for wall hangings of the present invention, the stand is screwed to the mounting plate, and the screw boss mutually reinforces the supporting rib, so It can withstand force sufficiently, and the reinforced screw boss receives the tightening force of the screw, so even if it is tightened too much, the deformation of the synthetic resin stand can be prevented and the mounting state can be strengthened. It is possible.

Further, when the stand is inserted into the mounting plate from above, the supporting ribs come into contact with each other so that the screw hole and the screw boss are aligned with each other, so that the screwing operation is easy.

Further, since the bottom plate can be applied to the supporting ribs, the bottom plate can be firmly fixed to the stand, and there is no fear that the bottom plate and the stand will come off and the wall-mounted fan will fall.
