Abstract

<P>PROBLEM TO BE SOLVED: To provide a vacuum cleaner whose handle can be always held from the upper side to be carried and is in a shape hard to be caught by furniture or the like. <P>SOLUTION: When this vacuum cleaner is stored in a standing position, an extension tube 10 is fixed on the bottom side of a cleaner body 4. Because a gripping handle 1 has no load, the handle 1 is positioned on the side of the cleaner body 4 in parallel with a coupling section 2, and does not obstruct the storage of the extension tube 9. When the cleaner body is lifted for use by gripping the handle, the handle 1 turns in relation to the coupling section because the handle 1 can rotate against an urging means with a restoration force so that the handle 1 can stay in the position parallel to a floor surface 12 and be always held from the upper side. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

    The present invention relates to a vacuum cleaner.

  In recent vacuum cleaners, even after cleaning is completed, the vacuum cleaner main body is left standing while being connected to the hose vacuum cleaner main body, and the extension pipe is further locked to the vacuum cleaner main body for easy storage. doing. Conventional vacuum cleaners of this type include, for example, stand storage diagrams as shown in FIGS.

  In FIG. 8, 1 is a handle part, 2 is a connection part, 3 is a cleaner body, 4 is a hose, and 10 is an extension pipe. The handle 1 is formed at the connecting portion 2 between the cleaner body 3 and the hose 4. When the cleaner body is carried, the handle 1 can be held and moved (see Patent Document 1).

  However, this type is formed so that the direction of the curved surface of the handle portion 1 faces the bottom surface of the vacuum cleaner body so that the handle portion 1 can smoothly enter and be easily gripped. Therefore, at the time of cleaning, the curved surface of the handle portion 1 may collide with or collide with an obstacle or furniture on the floor surface, and smooth cleaning may not be possible.

  Another example is shown in FIG. In FIG. 9, 1 is a handle part, 2 is a connection part, 3 is a vacuum cleaner main body, 4 is a hose, and 10 is an extension pipe. The handle 1 is formed at the connecting portion 2 between the cleaner body 3 and the hose 4. When carrying the cleaner body, the handle 1 can be held and moved (see Patent Document 2).

  However, in this type, the handle portion 1 is formed on the upper surface of the cleaner body in parallel with the connecting portion 2, so that when the cleaner body is drawn without using the handle portion 1 as in cleaning, Since there is no handle 1 on the bottom of the vacuum cleaner main body, it does not collide with or collide with obstacles or furniture on the floor, and it can be shaped like a streamline that is hard to get caught in furniture etc. However, when the handle portion 1 is used as in the case of carrying the vacuum cleaner body, it can be held only from the side of the handle portion 1 like a mug and is difficult to grasp.
