[0005]

However, in the above-mentioned conventional structure, when the same extension tube is used for the main bodies having different sizes (height when standing up), depending on the position of the hook portion A fitted with the main body. First because the height of the locking portion B changes
Since the storage height of the extension tube is changed, it becomes a constraint condition for setting the position of the main body locking portion A, and depending on the main body, the height during storage has to be increased. Also, as is clear from FIG. 9, the handle has a large overall height when stored,
A more compact storage form has been desired.

Further, when carrying in the stored state, the position of the hooking portion B is far from the hand portion on which the weight of the hose is applied, which is unstable. As a method of holding the attachment, there is a problem that the structure of the holding portion is complicated and the protruding portion is large and may be caught during cleaning.

The present invention solves the above-mentioned conventional problems. A first object of the present invention is to always obtain a minimum storage height even if the same extension tube is used for bodies of different sizes. That is.

A second object is to provide a method capable of reducing the storage height with the same number of operations. A third object is to improve the stability of the hand portion and the extension pipe when stored. Further, a fourth object is to provide a storage form that can be stored at the lowest height, is compact, and has good stability. A fifth object is to provide a method for holding an attachment which is easy to use and has a simple structure.

[0009]

The means according to the present invention for achieving the above-mentioned first object comprises a first hook for engaging with a first locking portion formed on the main body of the second extension tube. The stopper provided with the portion is fixed, the second locking portion is provided independently of the stopper, and the second hooking portion that fits into the second locking portion is formed in the first extension pipe. It is a thing.

In order to achieve the second object, the length of the first extension pipe is made shorter than the length of the second extension pipe by a maximum of about the length of the proximal portion.

In order to further achieve the third object, the second
The hooking part of is formed integrally with the hand part.

In order to achieve the fourth object, there is provided locking means for separating the first extension pipe from the proximal portion and storing and fixing the first extension pipe in front of the second extension pipe substantially in parallel. The engaging portion and the second hooking portion are arranged at positions where the upper end of the proximal portion and the upper end of the extension pipe are substantially at the same height when they are fitted to each other.

Further, in order to achieve a fifth object, the second extension pipe is provided with a first hooking portion and a second locking portion which are fitted to the first locking portion formed in the main body, A second hooking portion that fits into the second locking portion is provided on the first extension pipe or the proximal portion, and the second hooking portion has a support wall that is substantially vertical to the outer contour of the extension pipe or the proximal portion. And L down from the support wall
A guide wall extending in a letter shape is provided, and an attachment holder that extends upward from the support wall to form a gap between the guide wall and the substantially same plane as the guide wall is integrally formed.

[0014]

In the vacuum cleaner of the present invention having the above-mentioned structure, the extension pipes are made to serve as the second locking portion by adjusting the fixing position of the stopper according to the position of the first locking portion provided on the main body. Since the second hooks can be stored while being fitted to each other to the minimum storage height, use the same extension pipe for main bodies with different sizes (height of the first locking portion). The storage height can always be kept to a minimum.

Further, it is possible to lower the position of the hand portion which has restricted the storage height, and it is possible to reduce the total height during storage.

Further, since the extension pipe can be supported on the upper side against its own weight, the stability at the time of storage can be improved, and since the fitting position is at the upper side, storage and removal operations can be facilitated.

Then, both the second extension pipe and the proximal portion can be fitted or locked to the first extension pipe fitted to the main body so that the storage height can be minimized and at the same time the width can be accommodated within the width of the main body. It is possible to store it compactly.

Further, the attachment can be held at a position close to the hand side during cleaning by a simple and unobtrusive structure.
