Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upright type electric vacuum cleaner having a handle which is bendable with respect to a cleaner body.

[0002]

2. Description of the Related Art Conventionally, the upright type electric cleaning has a drawback that it tends to fall down when it is housed because the entire vacuum cleaner has a vertically long shape.
As described in Japanese Unexamined Patent Publication No. 6 (A47L 9/02), etc., the locking claws integrally formed on the connection pipe are locked to the ribs formed in the arm chamber of the floor nozzle main body, so that the cleaner main body is upright. It is known that it is fixed.

However, in the above structure, the locking claw is
Since it is located in the air flow path from the suction port of the floor nozzle body to the dust collection chamber of the vacuum cleaner body, if dust that is sucked in from the suction port gets entangled with its locking claws, it may reduce the suction force and cause noise. There is a problem such as becoming.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide an upright type electric vacuum cleaner capable of securely fixing the main body to the standing state with a simple structure.

[0005]

The first means of the present invention is to:
A floor suction tool having a suction port, a connection pipe rotatably attached to the floor suction tool in a tilting direction, a cleaner body connected to the connection tube, and an upper portion of the cleaner body And a handle that is bendable rearward with respect to the main body of the cleaner, and a locking portion is formed on the floor suction tool at a position facing the rotation axis of the connection pipe. In addition to forming a standing wall, a pivot on the connecting pipe is formed with a projection that rides over the engaging portion of the standing wall and engages with the engaging portion when the connecting pipe is raised, and the floor suction tool rear portion. Is characterized in that a fitting portion is formed in which the end portion of the bent handle fits in the standing state of the vacuum cleaner body.

A second means of the present invention is to connect a floor suction tool having a suction port, a connection pipe rotatably attached to the floor suction tool in the up and down direction, and a connection pipe. The main body of the vacuum cleaner, and a handle arranged on the top of the main body of the vacuum cleaner and foldable rearward with respect to the main body of the vacuum cleaner. When the cleaner main body is rotated, a restricting portion that contacts the connecting pipe and restricts the suction tool main body from rotating more than a predetermined amount is formed, and the handle is folded when the cleaner main body is in an upright state. It is characterized in that the ends of the handle are brought into contact with each other during bending.

[0007]

According to the structure of claim 1 of the present invention, when the cleaner main body is erected and the connecting pipe is rotated toward the front side of the cleaner main body when the cleaner is housed, it is formed on the rotating shaft of the connecting pipe. By engaging the protruding part over the locking part of the standing wall of the floor suction tool and locking it, bending the handle to the rear side of the vacuum cleaner main body and fitting the end part to the fitting part of the floor suction tool. It is possible to prevent the cleaner body from accidentally rotating backward and falling.

According to the second aspect of the present invention, when the vacuum cleaner is stored, the handle is bent while the vacuum cleaner main body is erected and the connecting pipe is rotated toward the front side of the vacuum cleaner main body. ,
By fitting the end part to the regulation part of the floor suction tool, the cleaner body is held in the upright state, and when the cleaner body is lifted with the handle extended, the suction tool body moves downward. When rotated, the connection tube comes into contact with the restriction portion, and the rotation of the suction tool body at a predetermined angle or more is restricted.
