Reference numeral 16 denotes a spring for urging the buckle 6.

[0004]

However, in the conventional vertical vacuum cleaner, when the handle 1 is stored in the handle storage portion 3, the upper end of the handle 1 is positioned higher than the upper end of the cleaner body 2. Therefore, there is a problem in that the size of the vacuum cleaner when it is packed becomes large, the useless space increases, and the packing efficiency deteriorates.

[0005] In view of the above, an object of the present invention is to provide a vertical vacuum cleaner in which a handle is detachable and packing efficiency is improved.

[0006]

As shown in FIG. 1, a pipe guide 35 includes an upper first vertical groove 40, a lower second vertical groove 41, and a first vertical groove. A horizontal groove 42 is formed to connect the lower end of 40 and the upper end of the second vertical groove 41, and the handle pipe 31 is provided with an engagement projection 43 for engaging with each of the grooves 40, 41, 42. It is detachable from the pipe guide 35. The angle formed by the first vertical groove 40, the second vertical groove 41, and the horizontal groove 42 is 90 degrees or less. And a locking means 4 for locking the handle pipe 31 to the pipe guide 35.
5 is provided, and the engagement protrusion 4
3 is located in the second vertical groove 41.

[0007]

In the means for solving the above problems, the packed vacuum cleaner is in a state where the handle body 22 is detached from the vacuum cleaner main body 21. When the handle 22 is mounted on the pipe guide 35 of the cleaner main body 21 in order to use the cleaner, the first vertical groove 40 and the engagement protrusion 43 are aligned, and the handle 22 is pushed down to engage. The mating projection 43 is moved downward along the first vertical groove 40. When the engagement projection 43 reaches the lower end of the first vertical groove 40, the handle body 22 is rotated to move the engagement projection 43 along the lateral groove 42. When the engagement protrusion 43 reaches the upper end of the second vertical groove 41, the handle body 22 is pushed down again to move the engagement protrusion 43 downward along the second vertical groove 41.

The handle body 22 is adjusted to an appropriate height, and the handle pipe 31 is locked to the pipe guide 35 by the engagement means 45, so that the handle body 22 is fixed and cleaning is performed. At this time, the engagement protrusion 43 is located in the second vertical groove 41, and the engagement protrusion 43 comes into contact with the side wall of the second vertical groove 41, and the handle body 22 is No rattling in the lateral direction. Further, even if the handle pipe 31 tries to slip out of the pipe guide 35 due to an erroneous operation, the engagement projection 43 abuts on the upper wall of the lateral groove 42 and does not move further upward and does not slip out. Moreover, if the angle formed by the first vertical groove 40, the second vertical groove 41, and the horizontal groove 42 is 90 degrees or less, the handle body 22 must be surely rotated in order for the handle body 22 to escape from the pipe guide 35. It is necessary to guide the engagement projection 43 along the lateral groove 42.

A lower second vertical groove 41 and a horizontal groove 42 connecting the lower end of the first vertical groove 40 and the upper end of the second vertical groove 41
Are provided.

The first vertical groove 40 and the second vertical groove 41 are
As shown in FIG. 4, a part of the wall surface of the pipe guide 35 is formed by projecting in a concave shape, and is shifted from each other by 90 degrees in the horizontal direction. The horizontal groove 42 is formed by piercing the wall surface of the pipe guide 35, and the angle between the first vertical groove 40 and the second vertical groove 41 is 90 degrees. In addition,
The pipe storage portion 34 is formed with a pipe storage vertical groove 34 a continuous with the second vertical groove 41. On the lower wall surface of the handle pipe 31, a convex engaging projection 43 which is detachably engaged with the first vertical groove 40 and guided by the grooves 40, 41, 42 is held through.

When the engaging projection 43 is located in the second vertical groove 41, that is, when the cleaner is used,
Pipe handle 3 with handle pipe 31 at multiple levels of height
5 is provided with locking means 45 for locking. As shown in FIG. 1, the locking means 45 engages with the engagement hole 46 formed in the upper wall surface of the pipe guide 35 and the engagement hole 46 provided above the engagement protrusion 43 of the handle pipe 31. It is composed of a plurality of lock pins 47 and a plurality of elastic bodies 48 for urging the lock pins 47 outward.

Each lock pin 47 is connected to the handle pipe 31.
It is attached to the band-shaped elastic body 48 disposed therein, and is disposed so as to penetrate a wall surface of the handle pipe 31 on the side opposite to the side on which the engagement protrusion 43 is disposed. The elastic body 48
Is composed of a C-shaped leg portion 49 that slides up and down along the inner wall of the handle pipe 31 and a flat top portion 50 that connects the leg portions 49, and a lock pin 47 is fixed to the center of the top portion 50. I have.

On the outer wall of the pipe guide 35, there is provided a pushing body 51 which presses the lock pin 47 to elastically deform the elastic body 48, thereby pushing the lock pin 47 into the handle pipe 31 to release the engagement. Screwed. The pushing body 51 is disposed so as to protrude from a pushing opening 52 of the cleaner body 21 shown in FIG. 3 and has a pushing pin 51 a at a position facing the engaging hole 46.

In the above configuration, the packaged vacuum cleaner has the handle body 22 detached from the vacuum cleaner main body 21. Then, in order to insert the handle body 22 into the pipe guide 35 of the cleaner body 21 and attach it to use the cleaner, as shown in FIG. Then, the engagement projection 43 of the handle pipe 31 is inserted, and the handle 30 is pushed downward to move the engagement projection 43 downward along the first vertical groove 40. At this time, the lock pin 47 of the handle pipe 31 is pressed by the inner wall of the pipe guide 35, and the elastic body 48 is elastically deformed and pushed into the handle pipe 31.

When the engagement projection 43 reaches the lower end of the first vertical groove 40 and contacts the lower wall of the horizontal groove 42, the handle 3
0 is rotated to move the engagement protrusion 43 along the lateral groove 42. When the engagement protrusion 43 comes into contact with the side wall of the second vertical groove 41,
The handle 30 is pushed down again to move the engagement protrusion 43 downward along the second vertical groove 41, and is inserted until the handle 30 comes into contact with the upper surface of the cleaner body 21.

When performing cleaning, the handle 3
When the lock pin 47 of the handle pipe 31 is fitted to the engagement hole 46 of the pipe guide 35, the lock pin 47 is engaged by the restoring force of the elastic body 48 as shown in FIG. The handle body 22 protrudes in the direction of the hole 46 and engages with the engagement hole 46 to fix the handle body 22 to the cleaner body 21. At this time, the engagement protrusion 43 is, as shown in FIG.
And abuts on both side walls of the second vertical groove 41. As a result, the handle body 22 is locked together with the locking by the lock pin 47.
No rattling in the horizontal direction.

On the other hand, in order to remove the handle body 22 from the pipe guide 35 of the cleaner main body 21, the engagement is released by pressing the pusher 51 and the lock pin 47 into the handle pipe 31 to reverse the engagement. The operation is performed.

As described above, since the handle body 22 is detachably attached to the cleaner main body 21, when packing the vacuum cleaner with the handle body 22 removed from the cleaner main body 21, packing is performed. The height when the vacuum cleaner body 21 is
Height L (see FIG. 3), the packing height is lower than when packing is performed with the conventional handle attached to the cleaner body, and the number of packings can be reduced. The handle 2
2 has no effect on the packing number if the cleaner main body 21 is put in the space at the time of packing.

Further, since the horizontal groove 42 is interposed between the first vertical groove 40 and the second vertical groove 41, when the height of the handle body 22 is adjusted, the handle body 22 is erroneously inserted into the pipe. Even if the user tries to get out of the guide 35, the engagement protrusion 43
Abuts on the upper wall of the lateral groove 42 and does not move upward any more, so that the handle body 22 can be prevented from coming off.

It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that many modifications and changes can be made to the above-described embodiment within the scope of the present invention. For example, as shown in FIG. 6, the lower end of the first vertical groove 40 is formed slightly lower than the upper end of the second vertical groove 41, and the horizontal groove 42a is inclined.
The angle C between the first and second vertical grooves 40, 41 and the horizontal groove 42a may be 90 degrees or less. In order to remove the handle body 22 from the pipe guide 35, the engaging protrusion 43 is guided to the lateral groove 42a, and then the handle body 22 is surely rotated so that the engaging protrusion 43 is obliquely downward along the lateral groove 42a. It is necessary to move and guide to the first vertical groove 40. This is to prevent the handle body 22 from rotating and being inadvertently pulled out due to an erroneous operation, since the handle body 22 is easily rotated when the lateral groove is horizontal. Can be prevented.
In addition, by inclining the lateral groove, the user can reliably perform the operation of rotating the handle body 22, and the user can reliably recognize the operation of removing the handle body 22.

Further, as shown in FIG.
Forming first and second vertical grooves 61, 62 and a horizontal groove 63,
An engagement protrusion 65 may be provided on the upper part of the inner wall of the pipe guide 64. Further, an engagement protrusion may be provided at a lower portion of the inner wall of the handle pipe, and first and second vertical grooves and horizontal grooves may be formed in the pipe guide, and the handle pipe may be externally inserted into the pipe guide.

Further, as shown in FIG.
Alternatively, the first vertical groove 71 and the second vertical groove 72 may be formed vertically apart from each other on a straight line, and the horizontal groove 73 connecting the lower end of the first vertical groove 71 and the upper end of the second vertical groove 72 may be spiral. Good.

[0026]

As is apparent from the above description, according to the first and second aspects of the present invention, since the handle body is detachable from the cleaner body, the handle body is cleaned when packing the cleaner. When packing is performed in a state where the packing is removed from the machine main body, the height at the time of packing is sufficient for the height of the vacuum cleaner main body, and the number of packing can be reduced. For this reason, packing efficiency is improved, and packing and transportation costs can be reduced. In addition, since the horizontal groove is interposed between the first vertical groove and the second vertical groove, even if the handle body tries to slip out of the pipe guide due to an erroneous operation, the engagement protrusion abuts on the wall surface of the horizontal groove and is further raised. Because it does not move
The handle body can be prevented from coming off.

According to the third aspect, since the angle formed by the first and second vertical grooves and the horizontal grooves is 90 degrees or less, it is necessary to perform an operation for surely rotating the handle in order for the handle to come off. Therefore, the handle body can be reliably prevented from coming off due to an erroneous operation. Further, it is possible to make the user surely recognize the operation of removing the handle body.

According to the fourth aspect, when the handle pipe is locked by the pipe guide, the engaging projection is located in the second vertical groove and abuts against the side wall, so that the handle is locked together with the locking means. The rattling in the lateral direction of the body can be reduced.
