Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a vacuum cleaner, and particularly to a handle provided on the vacuum cleaner body.

(Prior Art) Conventionally, as shown in Japanese Utility Model Publication No. 1984-843 and as shown in FIGS. A handle 4 having a presser part 3 for holding the two in a connected state is rotatably supported on the case 2, and the handle 4 can be held in a vertical or horizontal position. A vacuum cleaner is known that can be used both when positioned above and behind the storage case 2. However, in this structure, the handle 4 is attached to the storage case.
Because it is provided in the storage case 2, it can be used only when the vacuum cleaner main body 1 is stored in the storage case 2.The handle that can be used to carry the vacuum cleaner main body 1 taken out from the storage case 2 is There is only an upper handle 6 provided on the top of the machine body 1.

However, in general, with vacuum cleaners that have a handle on the top of the vacuum cleaner, the handle is located on the side when the vacuum cleaner is used with its back facing down. It is difficult to hold and move the vacuum cleaner body while standing, and it takes time and effort to carry the vacuum cleaner body.

Therefore, as shown in FIG. 7, a structure is adopted in which an upper handle 8 and a front handle 9 are provided separately at the upper center and front part of the cleaner body 7, respectively. However, since one of these handles 8 and 9 is used selectively, it is uneconomical to provide the two handles 8 and 9 on the cleaner body 7. In addition, with this structure, for example, when using the front handle 9 immediately after using the upper handle 8,
You have to change it each time, which takes time and effort.

In addition, as described in Japanese Utility Model Application No. 48-81652, a handle is rotatably supported on the vacuum cleaner body so that it can be held in a horizontal position and a vertical position, and when the handle is held in a horizontal position, The handle is located in front of the vacuum cleaner body, and when the handle is held in a vertical position, the handle is located above the vacuum cleaner body, and when the handle is held in a horizontal position, it is connected to the hose. A vacuum cleaner that holds an extension tube is also known.

(Problems to be solved by the invention) In the conventional vacuum cleaners shown in Fig. 5, Fig. 6, or Fig. 7 above, the handle was provided in a fixed position on the main body of the vacuum cleaner. If a handle is provided only on the top, it will be difficult to carry the vacuum cleaner when it is used in an upright position. In this case, there was a problem that it would be expensive.

Furthermore, in the vacuum cleaner described in Japanese Utility Model Application Publication No. 48-81652, when used with the handle held in a horizontal position, the grip part of the handle protrudes forward, and furthermore, this handle is usually made of plastic. Since the handle is made of hard material such as the handle, there is a problem in that it may cause damage when it comes into contact with features such as pillars or furniture.

This invention was created in view of the above problems.
One handle can be used as either an upper handle or a front handle, making it easy to carry the vacuum cleaner in its normal position or in an upright position, while also acting as a bumper when the handle is held horizontally. The company provides vacuum cleaners.
