Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric vacuum cleaner having a handle for carrying.

[0002]

2. Description of the Related Art A conventional floor-moving type vacuum cleaner is shown in FIG.
As shown in FIG. 3, a suction port 3 for connecting the connection hose 2 is provided on the front side of the cleaner body 1, and the suction port 3 is provided inside the cleaner body 1.
A dust bag 4 is detachably attached so as to communicate with, and an electric blower 5 is arranged on the rear side thereof. Further, as moving means of the cleaner body 1, casters 6 are attached to the front side of the bottom surface of the body, and wheels 7 are attached to the left and right sides of the rear side. And
The air sucked from the outside by the electric blower 5 through the connection hose 2, the dust bag 4, and the filter 8 passes through the electric blower 5 and is exhausted to the outside from the exhaust port 9 at the rear part.

In the above vacuum cleaner, the cleaner body 1
A handle 10 for carrying is usually provided on the upper surface of the cleaner body 1 and rotatably supported on the cleaner body 1 by a hinge 11. The handle 10 rotates until it is substantially vertical to the cleaner body 1, and its rotation is restricted by a protrusion or a surface so that the handle 10 can be fixed in that state.

As another form, a simple handle using a suction port and a lower member of the cleaner body is provided in front of the cleaner body (for example, actual open sho 63-6206).
No. 3 gazette (shown in FIG. 5)), one provided with a fixed handle on the lower member of the cleaner body, or one provided with a movable handle on the lower member of the cleaner body, etc. For example, there is the one described in FIG. 1 of Japanese Utility Model Publication No. 63-62063 or the one described in FIG. 2 of Japanese Utility Model Publication No. 63-52564.

[0005]

As described above, with respect to the handle provided at the front of the cleaner body using the suction port and the lower member of the cleaner body, the handle mechanism is simple and the cleaner is also clean. Since the shape is restricted by the design process of the main body, it is difficult to make full use of the original function of the handle, and when holding the handle for a long time, it is difficult to hold the hand, or difficult to hold.

Further, with respect to the one having the fixed type handle using the lower member of the cleaner body, etc., it is possible to obtain a shape and an operation feeling which are sufficiently satisfied with respect to the functions such as the original ease of holding the handle. The main body of the vacuum cleaner becomes large, the usability as an electric vacuum cleaner deteriorates, and the storability is also adversely affected.

Further, in the case where a movable handle is provided on the lower member of the cleaner body, etc., if the one which can be pulled out and slid from the cleaner body, the width of the cleaner body becomes large and the drawer is pulled out. If it is used as it is, it may damage furniture and the like, and may impair the design. For rotatable items, the handle provided on the main body of the vacuum cleaner is fixed by rotating it from below, and the handle is usually used with the connection hose connected to the main body of the vacuum cleaner. Since the handle interferes with the handle, the usability is poor, and the handle is located under the vacuum cleaner body when stored.
The handle may collide with an obstacle when the vehicle is over a threshold, and the handle may be destroyed, and the handle may pop out due to vibration or shock. In addition, if the handle is used in a protruding state, it may damage the floor surface or catch an obstacle.

When the main body of the vacuum cleaner is lifted in a horizontal state or when it is lifted in a vertical state,
When using a single handle as in the conventional case, the handle cannot be fixed vertically or forward due to the position of the center of gravity of the cleaner body and its weight, and the cleaner body becomes unstable. I will end up.

In view of the above, it is an object of the present invention to provide an electric vacuum cleaner having a neat appearance and improved handle usability.

[0010]

In the drawing, 34 is a caster, 35 is a wheel, 36 is a knob for opening and closing the case cover 24, and 37 is a grounding rib that supports the cleaner body 20 in a vertical state when standing upright, which serves as an electric vacuum cleaner. The basic function is the same as the conventional one.

In this embodiment, the handle 40 is provided on the front side of the cleaner body 20 so as to be rotatable above the connection hose 26 via the mounting shaft 41 so that the handle 40 is integrated with the cleaner body 20. A groove 42 to be housed in is formed in the cleaner body 20.

The handle 40 is a hollow resin body formed in a U-shape and in a side-view shape, and comprises a grip portion 43 and two base portions 44 for supporting the grip portion 43. As shown in FIG. 3, a hole 45 into which the mounting shaft 41 is fitted is formed on the inner side surface of the base portion 44. The end surface 44a of the base portion 44 of the handle 40 is inclined upward from the front side to the rear side of the cleaner body 20.

The groove 42 is composed of a vertical groove portion 46 formed on both sides of the lower body member 21 with the suction port 25 sandwiched therebetween, and a recess 47 formed in the case cover 24 above the suction port 25, as shown in FIG. As described above, by fitting the hole 45 of the handle 40 into the pair of mounting shafts 41 projectingly provided on the side wall surface of the vertical groove portion 46 on the suction port 25 side, the handle 40 is mounted on the mounting shaft 4.
It becomes possible to rotate around 1 around the vacuum cleaner body 20 in a direction in which it falls forward. In addition, the handle 4 is provided above the recess 47.
A gap is provided for inserting a hand to raise 0. As shown in FIG. 4, the mounting shaft 41 is attached to the vertical groove portion 46.
Is provided on the side wall surface of the main body lower member 21 side of the handle 40
A hole 45 into which the mounting shaft 41 fits may be formed on the outer surface of the base portion 44.

The depth of the groove 42 is made larger than the thickness of the handle 40, so that the handle 40 can be fitted and stored in the handle 40.
6, the distance from the center of the hole 45 to the farthest portion of the end surface 44a of the base 44 is slightly smaller. Also, the hole 4
The distance from the center of 5 to the horizontal wall 46a of the vertical groove 46 is made longer than the distance from the center of the hole 45 to the farthest portion of the end surface 44a of the base 44, and when the handle 40 is tilted forward as shown in FIG. The handle 40 can rotate without coming into contact with the groove 42, and the base 44 of the handle 40 abuts the vertical wall 46b of the vertical groove 46 to prevent further downward rotation. In this state, the handle 40 is fixed, and the position of the grip portion 43 of the handle 40 coincides with the horizontal line L passing through the center of gravity of the cleaner body 20, as shown in FIG.

With such a structure, when the electric vacuum cleaner is used, the handle 40 is tilted to the cleaner main body 20 side and stored in the groove 42. In this state, the handle 40 does not protrude from the outer surface of the cleaner body 20 and has a neat appearance. Also, the cleaner body 20
Since the handle 40 is located on the upper half side of the cleaner main body 20 when the vehicle climbs over the threshold or collides with an obstacle, it is not destroyed or damaged. Even if the handle 40 floats and falls forward, rotation is restricted when the base portion 44 of the handle 40 comes into contact with the wall surface of the groove 42, and the handle 40 does not interfere with the connection hose 26. There is no hindrance. The dust bag 3

Next, when the handle 40 is tilted to the front side, the end surface 44a of the base 44 of the handle 40 has the vertical groove portion 4 of the groove 42.
It rotates around the mounting shaft 41 until it comes into contact with the vertical wall 46b of No. 6, and the rotation is restricted at a predetermined position, and it is in a fixed state. In this state, the grip portion 43 of the handle 40 is located on the same horizontal plane as the center of gravity of the cleaner body 20. Therefore, when carrying the cleaner body 20, the cleaner body 2
0 is in a vertical state, the weight of the cleaner body 20 is entirely applied to the handle 40, no extra force is required without wobbling, and stability when held is increased. Furthermore, the vacuum cleaner body 20 is set upright by the wheels 35 and the grounding ribs 37 simply by lifting the vacuum cleaner body 20 and lowering it. Therefore, the connection hose 26 can be used or stored in a stable state without tilting when cleaning a high place or storing it when not in use.

Here, as another method for fixing the handle 40 at a predetermined position, as shown in FIG. 7, the depth above the vertical groove portion 46 is equal to the thickness of the handle 40, and the depth below the center of the hole 45 to the base portion 44 of the handle 40. The depth is set to be equal to or larger than the distance to the farthest portion of the end surface 44a so that the base portion 44 can rotate without contacting the vertical wall 46b. An upper wall 48 is formed at a portion connecting the both sides, and when the rear side surface of the base portion 44 comes into contact with the upper wall 48, the handle 40 cannot be tilted further forward and is fixed at a predetermined position. It

(Second Embodiment) In this embodiment, as shown in FIGS. 8 and 9, a torsion coil spring 50 is provided as an urging body for urging the handle 40 in the housing direction. The torsion coil spring 50 is wound around the mounting shaft 41, one end is fixed to the base portion 44 of the handle 40, and the other end is fixed to the side wall surface of the suction port 25. By the way, instead of the torsion coil spring 50, a tension spring is used as a biasing body for the handle 4.
It may be interposed between 0 and the cleaner body 20. The other structure is the same as that of the first embodiment.

As a result, when the handle 40 is tilted forward and used, and then the hand is released from the handle 40, the handle 40 is naturally returned by the urging force of the torsion coil spring 50 and is in the stored state. That is, when the user does not intentionally use the handle 40, the handle 40 is always attached to the cleaner body 2.
It is stored in 0. Therefore, it is possible to prevent forgetting to store the handle 40, and the handle 40 does not fall forward due to vibration or the like during cleaning, and damage to furniture or the like can be prevented.

Further, a handle is provided on the front side of the cleaner body so as to be rotatable above the connection hose via a mounting shaft,
A groove is formed in the cleaner body so that the handle is integrated with the cleaner body, and a movable piece that is retracted into the groove when the case cover is opened and closed is provided inside the suction port. Since the piece protrudes into the groove,
The handle cannot be stored in the groove without closing the case cover. Therefore, the handle is not obstructed during the replacement of the dust collecting bag, and the replacement work is facilitated.

Further, a handle is rotatably provided on the upper side of the cleaner body through a mounting shaft, and a groove is formed in the cleaner body for accommodating the handle which is tilted rearward so as to be integrated with the cleaner body. Since the handle is held in the vertical state and the state in which the handle is tilted forward, when the handle is stored, it is integrated with the main body of the cleaner, and a neat appearance is obtained, which is excellent in design. Moreover, by holding the handle in each state, one handle can be used properly in a stable state according to the purpose of use, and an inexpensive and convenient handle can be provided.
