Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a shoulder-type vacuum cleaner.

Conventional configuration and its problems A conventional example will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is an electric blower, 2 is a main body, 3 is a filter device, and 4 is a dust collection box, all of which are integrally formed with an attachment hole 6 for attaching a shoulder strap 5. Reference numeral 7 denotes a band attachment fitting, which is attached to the attachment hole 6 of the dust collection box 4.

Reference numeral 8 denotes a metal fitting for attaching and detaching the band, which is attached to the band 5 with a box-shaped metal fitting 9. Reference numeral 10 denotes a caulking bolt for attaching the band 5 to the box-shaped metal fitting 9.

In the above configuration, the main body 2 of the shoulder band 5
In order to attach and detach the dust collection box 4, the band 5 is removed from the band attachment fitting 7 by pushing out the band attachment/detachment fitting 8 attached to the band 5.
At this time, in order to ensure strength during normal use, the band attachment/detachment metal fitting 8 is made of a strong material such as stainless steel, and the thickness of the plate is relatively thick. It required a considerable amount of force to spread out the 8, and was extremely difficult to use.

Further, three parts constituting the band attachment part are required: a band attachment fitting 7, a band attachment/detachment fitting 8, and a box-shaped fitting 9, and the cost thereof is also high.

Purpose of the invention The present invention solves the above-mentioned conventional drawbacks and provides a shoulder-type vacuum cleaner that is inexpensive and easy to use.

Structure of the invention The vacuum cleaner of the invention has a lower end fixed to a dust collection box, and a buckle metal fitting integrally formed with a band metal holding part, and a dust collection box, which is integrally formed with the band metal holding part. The desired purpose has been achieved by forming a mounting hole for a band fitting between the two and providing a band hook portion having an undercut portion facing the band fitting.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings. In FIGS. 3 and 4, reference numeral 11 denotes a main body containing an electric blower (not shown), and has a buckle 13 for detachably holding a main body switch 12 and a dust collection box 14.

Reference numeral 15 designates an air intake port, and reference numeral 16 designates a band hook portion formed integrally with the dust collection box 14.

Reference numeral 17 denotes a buckle fitting having a buckle hooking part 18, which is fixed to the mounting boss 19 of the dust collection box 14 with a screw 20, and a band hooking part 1 on the front side.
A band fitting holding part 22 is formed corresponding to the cut hole 21 for forming the band 6 on the mold, and an undercut part 24 is formed to prevent the band fitting 23 from falling downward. Further, an undercut portion 16' is formed at the tip of the band hooking portion 16 to prevent the band metal fitting 23 from slipping down. Reference numeral 27 is a hole for attaching a band fitting formed by the band hooking part 16 and the band fitting holding part 22. 25 is a band, and 26 is a rivet. Note that the band fitting 23 may be a figure-of-eight fitting to reliably prevent it from coming off.

With the above configuration, when the band 25 is attached to the dust collection box 14, the band metal fitting 23 fixed to the band 25 is set from below the band hooking part 16 upwards as shown by the arrow. At this time, an undercut 24 to prevent the band 25 from coming off is formed on the band metal holding part 22 of the buckle metal fitting 17, but the lower end of the buckle metal fitting 17 is attached to the dust collection box 14, and the upper part is free. Therefore, the buckle metal fitting 17 falls down as shown by the arrow, and the band metal fitting 23 can be easily set in the dust collection box 14.

Moreover, once the band fitting 23 enters the attachment part, an undercut is provided in the band fitting holding part 22, so that the band fitting 23 does not come off from the band hooking part 16 of the dust collection box 14 during normal use. It is.

Effects of the invention As described above, according to the invention, the band fitting can be attached and detached from the dust collection box smoothly and reliably.
In addition, the only part needed to attach the band to the dust collection box is the band metal fittings, which makes it possible to provide an inexpensive product.
