Description

[Detailed description of the invention] The present invention relates to a buckle attachment device for a storage case of a vacuum cleaner, etc., and in particular, the purpose of this invention is to easily and securely attach a buckle to a storage case. It is.

Conventional buckle devices for storage cases include those in which the buckle is attached to the buckle case using a holding plate and screws, and those in which the buckle is inserted into the buckle case with some pressure, but the former has a large number of parts; Also, it requires a lot of man-hours to install, and although the latter requires only pressing, when storing and carrying the main body of a vacuum cleaner, etc., the weight of the storage case and accessories is on the rotating shaft of the buckle. The drawback was that it required strength.

The purpose of the storage case buckle attachment device of the present invention is to eliminate these drawbacks and easily and securely attach the buckle to the storage case. A case will be described in which an embodiment of the device is implemented as a buckle attachment device for a storage case of a vacuum cleaner.

Reference numeral 1 denotes a vacuum cleaner main body (equipment) that includes a built-in electric blower or the like (not shown), and has a handle 2 for carrying. Reference numeral 3 denotes a storage case for storing accessories such as a hose, an extension pipe, a suction port, etc. (all not shown), and has an opening so that a part of the vacuum cleaner main body 1 can be inserted from the top. A buckle 5 is provided in an opening 4 formed on the side of the storage case 3 at a distance below the upper end of the case 3 so that the storage case 3 and the vacuum cleaner main body 1 are connected when the vacuum cleaner body 1 is inserted. Reference numeral 6 denotes a buckle case provided in the storage case 3, and both side walls thereof have insertion holes 8, 8 on both sides of the side opening 4, and serve as shaft supporting walls for supporting the rotating shaft 7 of the buckle 5. The buckle 5 is rotatably attached by inserting the buckle 5 between the both side walls of the buckle case 6 with some pressure and inserting the rotating shafts 7 on both sides into the insertion holes 8, and the buckle 5 is attached to and detached from the vacuum cleaner body 1 by rotation. . 9 is a spring that always biases the buckle 5 in the engagement direction;
The vacuum cleaner body 1 and storage case 3 are separated by engagement of the buckle 5.
and are kept in a combined state.

The difference between the diameter d ₁ of the rotating shaft 7 on both sides of the buckle 5 and the diameter d ₂ of the insertion hole 8 of the buckle case 6 is the difference between the upper end of the buckle 5 and the storage case 3 when the buckle 5 is attached to the storage case 3.
The relationship between h and the gap h is as shown in the following equation.

h<d ₂ −d ₁ In the above embodiment, the vacuum cleaner body 1 is attached to the storage case 3, and the buckle 5 is attached to the vacuum cleaner body 1.
When the vacuum cleaner body 1 is combined with the handle 2 and carried, the rotating shaft 7 of the buckle 5 is smaller than the insertion hole 8, so the buckle 5 can be lifted by the gap between them. However, since h< _d2 - _d1 , the upper end 10 of the buckle 5 comes into contact with the upper edge of the side opening 4 of the storage case 3 before the rotating shaft 7 of the buckle 5 comes into contact with the buckle case 6.

Therefore, when the vacuum cleaner main body 1 and storage case 3 are combined and carried by the handle 2, the weight of the storage case 3 and accessories will not be concentrated on the rotation shaft 7, and the weight of the storage case 3 and accessories will not be concentrated on the rotation shaft 7. Great strength is not required, and the buckle 5 can reliably maintain its attached state.

In the above embodiment, the relationship h < d ₂ - _{d 1} is set, but even if the relationship h = d ₂ - d ₁ is set, the weight will not be concentrated on the rotating shaft 7, and the same effect can be achieved. can be expected.

As described above, in the present invention, by avoiding the concentration of the weight of the storage case and accessories on the rotating shaft, the rotating shaft does not require great strength, which simplifies component design. It is possible to easily put into practical use an excellent mounting device that can be mounted with an extremely simple operation of inserting the shaft with some pressure and fitting the rotating shaft into the insertion hole, and that can reliably maintain the mounted state.
