Abstract

PURPOSE:To provide a vacuum cleaner mounted with a lid and a handle both improved in the appearance. CONSTITUTION:Inner rotary shafts 73 of arm parts 71 of a lid 24 are inserted into rotation holes 66 respectively. The two arm parts 71 sandwich an upper body case member 26 to engage with the member 26 rotatably. Outer rotary shafts 76 of a handle 60 are inserted into long holes 67, so that the handle 60 is mounted on the upper body case member 26 rotatably by widening force of the handle body 26. An engaging surface 77 is placed on a peripheral surface on rotation holding parts 72 of the arm parts 71 of the lid 24, and positioned with preventing the handle 60 from going down. In long holes 67 below the outer rotary shafts 76 of the handle 60, closing members 78 to close the long holes 67 are arranged to close lower parts of the long holes 67. Thus, the outer rotary shafts 76 of the handle 60 are prevented from dropping off. Further, appearance can also be improved by this.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having an improved appearance to which a lid and a handle are attached.

[0002]

2. Description of the Related Art Conventionally, an electric vacuum cleaner having a lid and a handle rotatably attached to a main body of the vacuum cleaner has a structure as shown in FIG. 7, for example.

In the structure shown in FIG. 7, a pair of recesses 2 are formed on the upper surface of the cleaner body 1, and a cover 3 for closing the opening of the dust collecting chamber and a gripping handle 4 are rotated in the recesses 2. Install freely.

An inner surface portion 5 is formed on the center side of the pair of recesses 2 and is perpendicular to the rotating shafts of the lid portion 3 and the handle 4, and an outer surface portion 6 is formed opposite to the inner surface portion 5. Has been done. Further, an inner surface rotation shaft 7 is formed on the inner surface portion 5 so as to be perpendicular to the inner surface portion 5, and an outer surface rotation shaft 8 is formed on the outer surface portion 6.
Are formed so as to project.

Further, a turning hole 9 formed in the handle 4 is rotatably attached to the inner turning shaft 7, and a rotating portion of an arm 10 attached to the lid 3 is turned on the outer turning shaft 8. Moving recess
11 is rotatably attached.

Thus, the lid 3 and the handle 4 are rotatable with respect to the cleaner body 1.

[0007]

However, in the case of the conventional electric vacuum cleaner shown in FIG. 7, when the cleaner body 1 is formed, the opening 12 must be formed in the bottom surface of the recess 2 for die cutting. However, since the closing member 13 is provided in the opening 12, there is a problem that the appearance of the bottom surface of the concave portion 2 which is conspicuous during use is impaired.

The present invention has been made in view of the above problems, and an object thereof is to provide an electric vacuum cleaner in which a lid and a handle are attached with an improved appearance.

[0009]

According to the present invention, a vacuum cleaner body is provided with a recess, and a cover for closing an opening of a dust collection chamber and a gripping handle are rotatably attached to the recess. In the machine, one of the lid and the handle has an inner rotating shaft that is formed to project inward so as to project inward, and a rotating shaft that is coaxial with the inner rotating shaft and has a diameter larger than the inner rotating shaft. The other one of the lid and the handle has a peripheral surface portion serving as a peripheral surface, and the other one of the lid body and the handle is coaxially projecting outwardly in the opposite direction, and the peripheral surface portion-shaped external rotation shaft. An inner surface portion and an outer surface portion that are formed to face each other perpendicularly to the rotation axis of the lid and the handle, and the inner surface portion. And a bottom surface portion serving as a bottom surface of the outer surface portion and one of the inner surface portion and the outer surface portion, A rotation hole that rotatably holds one of the side rotation shaft and the outer rotation shaft, and a hole that is formed in the other of the inner surface portion and the outer surface portion and that faces the rotation hole. It has a long hole which is continuous to the bottom surface and which rotatably holds one of the inner rotating shaft and the outer rotating shaft.

[0010]

According to the present invention, a long hole is formed in either the inner surface portion or the outer surface portion of the recess formed in the cleaner body, and either the inner surface portion or the outer surface portion facing the long hole is formed. Since the turning hole is formed on the other side, and the inner and outer turning shafts of the lid and the handle are formed in the long hole and the turning hole, respectively, it is necessary to separately form the die-cutting hole in the recess as in the conventional case. Since it is eliminated, it is possible to improve the appearance and rotatably attach the lid and the handle.
