DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a case in which accessories such as a hose are housed in a case having an upper opening, and a cleaner main body is mounted and housed in a mounting portion formed in the upper opening. The present invention relates to a structured vacuum cleaner with a storage case.

[0002]

2. Description of the Related Art As this kind of conventional technology, Japanese Patent Publication No. Sho 64
Japanese Unexamined Patent Application Publication No. 6-6771, Japanese Utility Model Publication No. 4-27487, Japanese Utility Model Publication No. 3-21717, and the like.

[0003] Japanese Patent Publication No. 64-6771 and Japanese Utility Model Publication No. 4-27487 disclose a lower part of a step portion such as a bumper provided horizontally over the entire circumference of a cleaner body. A step portion such as a bumper is placed on the upper surface of the opening by fitting into the upper opening edge. In addition, before and after these storage cases, there are provided buckles and clamps for detachably connecting the main body of the vacuum cleaner to the storage cases, so that both can be safely carried in a state where both are connected. The vacuum cleaner body can be taken out of the storage case by releasing the connection by the clamp or the clamp.

[0004] Further, Japanese Unexamined Utility Model Publication No. Hei 3-21717 discloses a structure in which a vacuum cleaner main body can be easily placed and stored in an upper case of a two-stage storage case. No fixation with such a buckle or clamp is performed.

[0005] By the way, this type of vacuum cleaner with a storage case is placed in a storage place such as a closet after storing accessories such as hoses and the main body of the vacuum cleaner in the storage case after the cleaning is completed. It is taken out of a storage place such as a closet and used.

However, in the apparatus disclosed in the above publication, when moving the storage case out of a closet or the like, the heavy storage case storing the cleaner body and its accessories must be lifted and carried. No.

[0007] On the bottom of the storage case as described above,
It is conceivable to provide a small wheel such as a caster attached to the bottom surface of various storage cases so that a heavy storage case can be moved without being lifted.

[0008]

However, even with a small wheel such as a caster on the bottom surface of the storage case, it is necessary to bend the body and pull or push the storage case in and out of a closet or the like. It is quite difficult.

In such a case, it is convenient if the user can lift the front of the storage case to move it. However, in the case of a small wheel such as a caster on the bottom surface of the storage case, the storage is immediately performed when the front of the storage case is lifted. The lower part of the rear end of the case touches down and the rear caster also floats. Therefore, when the rear caster is in contact with the ground, the front of the storage case is slightly lifted, and its center of gravity is almost the same position as in the normal horizontal state, so the lifting load is heavy, and there is a problem in mobility in that state. .

When the storage case is lifted up and moved, the storage case is tilted, and there is a risk that the storage case may fall over or fall off due to excessive tilting. In Japanese Patent Publication No. 64-6771 and Japanese Utility Model Publication No. 4-27487, there is no danger because the cleaner body is fixed to the storage case with a buckle or a clamp. It takes time to store and retrieve. On the other hand, in Japanese Utility Model Publication No. 3-21717, storage and removal of the cleaner main body can be easily performed, but if the storage case is tilted, the cleaner main body is likely to fall off.

Therefore, the present invention has been made to solve such a problem.
An object of the present invention is to provide a vacuum cleaner with a storage case, which can lift one side of the storage case and easily move with a small force.

When one side of the storage case is lifted and moved as described above, the storage case falls over, or the stored vacuum cleaner body falls off without using a buckle or a clamp which is troublesome for storage and removal. It is an object of the present invention to provide a vacuum cleaner with a storage case that does not have any problem.

[0013]

SUMMARY OF THE INVENTION In order to achieve the above-mentioned object, the present invention is to accommodate accessories such as a hose in a case having an upper opening and a mounting portion formed in the upper opening. A vacuum cleaner with a storage case configured to place and store the cleaner body therein, comprising a wheel on a lower portion of one side of the storage case, and forming a handle on the other side of the case, When the other side of the storage case is lifted by the handle and moved by the wheels, the perpendicular line of the center of gravity of the cleaner body and the storage case is positioned near the wheels.

Further, a stopper is formed at a lower portion of one side of the storage case, the stopper portion restricting rotation of the storage case toward one side of the storage case about a wheel as a fulcrum.

Further, in a state where the cleaner main body is mounted on the mounting portion, the wheel of the cleaner main body abuts on the storage case at substantially the same height as the axle of the wheel or at a position above the axle. Is provided.

Further, the storage case is formed with a convex portion which fits into a concave handle provided on a lower surface side of a front portion of the cleaner body.

Further, in a state where the cleaner main body is placed on the mounting portion in the storage case, the cleaner body faces the front of the cleaner main body, and when the cleaner main body rotates around the wheel, the front of the cleaner main body is rotated. Is formed in a contact portion where the contact portion contacts.

A convex portion 43 is formed at the front of the opening edge to fit into the concave handle 6 formed on the front lower surface of the cleaner body 1. Thus, the concave handle 6 normally provided on the cleaner body 1 is used.
By effectively utilizing the above, the front and rear positioning of the cleaner main body 1 can be performed only by forming the convex portion 43 on the upper case 40, so that the configuration can be made inexpensively. In addition, with this configuration, the backlash of the cleaner main body 1 in the front-rear direction can be prevented, and also when the front of the storage case 20 is lifted, the cleaner main body 1 is supported by the convex portion 43, so that the cleaner main body 1 also has a falling-off prevention function. .

Further, the rear wall (contact portion) of the upper case 40 against which the stored rear wheel 3 of the cleaner main body 1 contacts is above the axle 3a of the rear wheel 3 on the main body side (1/2 or more of the rear wheel 3). ). Thereby, the storage case 20
Even when the cleaner main body 1 is tilted when the front is lifted, the rear wheel 3 does not ride on the rear wall of the upper case 40, and such falling off can be prevented.

Further, the inner surface (contact portion) 4 of the upper case 40 facing the front surface 1a (front cover 4) of the cleaner body 1.
0a is formed so as to be located close to a certain depth. That is, when the front of the storage case 20 is lifted, the cleaner main body 1 that tilts rearward with the rearward tilt of the storage case 20 rotates rearward around the rear wheel 3 as the rotation of the cleaner main body front surface 1a. It is configured such that a part thereof abuts on a part of the inner surface 40a of the upper case so as to function to regulate.

On the other hand, insertion holes 44, 44 for inserting the two separated connecting pipes 12, 12 into the lower case 30 in the vertical direction are formed on both sides of the rear part of the upper case 40. A storage pocket 45 for storing accessories such as a spare paper pack 13 and a round brush is formed between the insertion holes 44.

Next, storage and removal of accessories such as the cleaner body 1 and the hose 10 into and from the storage case 20 will be described.

As shown in FIGS. 5 and 6, the accessories are first stored in the upper case 40 through the upper opening 41 of the hose 1.
0, and one joint part of the hose 10 (the hand-operated side joint part 10a is housed first in the figure) between the U-shaped guide ribs 34, 34 provided behind the lower case 30.
, The hose 10 is rotated once, and the other joint part (in the figure, the main body inlet insertion side joint part 10b) is stored, and the floor suction tool 11 is stored thereon (even if the storage direction is reversed in the figure). good).

The removal may be performed at random. The opening 41 formed in the upper case 40 of the storage case 20 is
A sufficient space for storing and taking out the hose 10 and the floor suction tool 11 is ensured.

Therefore, there is no need to remove the upper case 40 of the storage case 20 for storage and removal.

Next, the two connecting pipes 12, 12 are housed one by one in insertion holes 44, 44 formed on the right and left rear. At this time, the structure can be stored at a predetermined position by simply storing the storage pocket 45 provided at the rear center portion of the upper case 40 and the U-shaped guide ribs 34 provided at the lower case 30 at random. ing.

In a storage pocket 45 provided at the rear central portion of the upper case 40, accessories such as a spare paper pack 13 and a round brush are stored.

On the other hand, as shown in FIGS. 7 and 8, when the cleaner body 1 is stored, the handle 7 of the cleaner body 1 is held upright and the opening 4 of the storage case 20 (upper case 40) is held.
1 Just insert the rear wheel 3 so that it matches the rear part,
It can be stored at a predetermined position (position where the main body side rear wheel 3 is placed on the case side rear wheel receiving portion 42 and the case side convex portion 43 is fitted to the main body side concave handle 6).

The main body 1 can be easily taken out simply by raising the handle 7 of the main body 1 and lifting it up.

As described above, the cleaner main body 1 can be stored simply by placing it on the top. At this time, since the large rear wheel 3 is positioned, it can be stored very easily and easily. Further, a special mechanism (for example, a clamp or the like) for positioning and fixing is not required, and can be provided at low cost.

Next, a description will be given of the case of movement in the housed state.

In the housed state shown in FIG.
The vertical line a of the center of gravity (near the fulcrum of the handle 7) and the vertical line b of the center of gravity of the storage case 20 (center of the case) are located almost in the middle between the front wheel 31 and the rear wheel (ground point c) 32.

FIG. 9 shows a state in which the user lifts the handle 21 in front of the storage case 20 in this state.

In this embodiment, since the rear wheel 32 of the storage case 20 is attached to the lower portion of the rear end of the storage case 20, the perpendiculars a and b of the center of gravity of the cleaner body 1 and the storage case 20 are indicated by the rear wheels. 32, the front of the case can be lifted and moved, and the load of the cleaner body 1 and the storage case 20 is applied to the rear wheel 32. Therefore, the lifting load at the time of movement is reduced, and the mobility is improved. .

When taking out from a closet or the like,
The user simply lifts the handle 21 in front of the storage case 20, and the rear wheel 32 of the storage case 20 moves forward and is pulled out in this state, so that the user can easily take out the storage case 20 without using excessive force.

Further, when the rear wheel 32 is lifted more than the above,
Since the stopper portion 33 projecting obliquely downward from below touches the ground and the rear wheel 32 is in a floating state, the user feels a sense of incongruity and does not lift any more, so that the storage case 20 falls backward. Can be prevented.

Even when the front of the case is lifted as described above, the rear wall of the upper case 40, which is in contact with the rear wheel 3 of the cleaner main body 1, is located above the axle of the rear wheel 3 of the main body (1 of the rear wheel 3).
/ 2 or more), the rear wheel 3 does not ride on the rear wall of the upper case 40 even when the cleaner body 1 is tilted, so that the cleaner body 1 can be prevented from falling off. .

Further, since the case-side convex portion 43 is fitted to and supported by the concave handle 6 on the front lower surface of the cleaner body 1, the front of the storage case 20 is lifted, and the storage case 20 is moved rearward. Even if it is tilted, the rearward movement of the cleaner main body 1 is prevented, so that this also functions as a fall prevention function.

Further, the inner surface 40a of the upper case 40 facing the front surface 1a (the front cover 4) of the cleaner body 1 is
Since it is formed so as to be located close to a certain depth, as shown in FIG.
When the cleaner body 1 tries to tilt backward with the inclination of
The front surface 1a and the like abut the case inner surface 40a and the like, and the function of restricting the rotation of the cleaner body 1 about the rear wheel 3 is used.

[0048]

As described above, according to the present invention, a wheel is provided at the lower portion of one side of the storage case, and a handle is formed on the other side of the case. When moving, the vertical line of the center of gravity of the cleaner body and the storage case is configured to be located near the wheel, so that when the handle on the other side of the case is lifted and moved, the load of the cleaner body and the case is reduced. Since it is applied to the wheel on one side, the movement in the stored state can be easily moved with a small force by lifting one side of the storage case, and the effect of improving the mobility can be obtained.

Further, a stopper portion is formed at the lower portion of one side of the storage case to restrict the rotation of the storage case toward one side of the storage case with the wheel as a fulcrum, so that one side of the case can be lifted as described above. There is no risk of the storage case falling backward.

Further, the storage case is provided with a contact portion with which the wheel of the cleaner body abuts at substantially the same height as the axle of the wheel or at a position higher than the axle in a state where the cleaner body is placed on the placement portion. As a result, even if the case is lifted as described above and the inclination of the cleaner main body is increased, there is no fear that the wheels of the cleaner main body may get over the contact portion and fall off.

Further, since the storage case is formed with a convex portion that fits into a concave handle provided on the lower surface of the front part of the cleaner body, the cleaner body is provided with a case on the concave handle on the lower surface of the front part. Since the side projections are fitted and supported, they function as a fall-preventing function with an inexpensive configuration.

When the main body of the vacuum cleaner is placed on the mounting portion, it faces the front of the main body of the vacuum cleaner, and when the main body of the vacuum cleaner rotates around the wheels, the front side of the main body of the vacuum cleaner contacts the housing. By forming the abutting contact portion, even when the cleaner body is tilted rearward by lifting one side of the case, there is no danger that the cleaner body will rotate and fall around the wheels.
