Description

[Detailed description of the invention] This invention relates to an improvement of a wall-mounted electric fan.

As shown in FIGS. 1 to 3, a conventional electric fan of this type has a blower section 4 consisting of an electric motor 1, blades 2, and a guard 3 attached to a stand 6 through a neck piece 5.
was supported. This stand 6 has an auxiliary plate 8 with an opening 7 formed at its bottom fixed with screws 9, and a wall 10
Pass the wall mounting plate 11 fixed to through the opening 7,
A thumbscrew 12 is inserted through the stand 6 and the auxiliary plate 8 and is screwed into this.

Due to this configuration, the thumbscrew 12 protrudes from the top of the stand 6, which not only looks bad, but also makes the packaging device complicated because the protruding portion gets in the way during packaging, and it is difficult to package the product. Become something. Furthermore, the molding of the stand 6 includes a mold that moves toward the neck piece 5 side and the wall 10 side.
There were drawbacks such as the need for a slide mold for forming the through hole of the thumbscrew 12.

This invention was made in view of the above-mentioned drawbacks, and the purpose is to provide an electric fan that does not have screws such as thumbscrews protruding, has a good appearance, and is easy to package.

Hereinafter, one embodiment of this invention will be explained according to FIGS. 4 to 6. In the figures, 1 to 5, 10, 1
2 indicates the same or equivalent part as the above conventional example, and 1
Reference numeral 5 denotes a wall mounting bracket fixed to the wall 10, which is formed into an L-shape with a claw 16 at the end, and a female thread 17 that engages with the thumbscrew 12 on the surface where the claw 16 is formed, and the other surface. has a mounting hole 19 through which a wood screw 18 passes.
is drilled. Reference numeral 20 denotes a stand molded from synthetic resin, which has an engagement hole 21 and a U-shaped recess 22 that engages with the claw 16 that is open on the neck piece 5 side.
A hole 23 through which the thumb screw 12 passes is formed by providing a stepped portion on the bottom surface of the recess 22 so as to remove the wall thickness.

In the electric fan configured as described above, the wall mounting bracket 15 is fixed to the wall 10 with wood screws 18, the claws 16 of the wall mounting bracket 15 are engaged with the engagement holes 21 of the stand 20, and the thumb screws 12 are tightened. The stand 20 is fixed by passing through the hole 23 and screwing it into the female thread 17 of the wall mounting bracket 15. At this time, the thumb screw 12 does not protrude from the outer wall of the stand 20 due to the recess 22. In addition, the recess 22 and the engagement hole 2 are arranged so that the neck piece 5 side is opened in this way.
1. Since the hole 23 is formed, the structure can be simplified by using a mold that can be moved to the neck piece 5 side and the wall 10 side.

As explained above, this invention consists of a wall mounting bracket that is fixed to the wall, a stand that is engaged with the wall mounting bracket, and a device that penetrates the side wall of the stand and is screwed into the wall mounting bracket to clamp the stand. A recessed portion is provided on the side wall surface of the stand so that the thumb screw does not protrude beyond the outer periphery of the side wall surface, which provides a good appearance, simplifies the packaging device, and facilitates work. Furthermore, since the thumbscrew does not protrude, damage to the thumbscrew is also eliminated.
