Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle rotating structure for a vertical vacuum cleaner.

[0002]

2. Description of the Related Art In a conventional vertical vacuum cleaner, when in use, the handle is extended above the main body, and the entire vacuum cleaner is moved forward, backward, left and right on the cleaning surface by a suction tool connected to the lower end of the main body. While inhaling dust, when not using a vacuum cleaner, store the handle in the main unit, remove it, or rotate it to the rear of the main unit to reduce the overall height and lean it in the corner of the room. There was one that made the storage space small when storing in a closet.

In particular, the handle is rotated to the rear of the main body of the vacuum cleaner to reduce the total height to reduce the storage space.
Some were disclosed in Japanese Utility Model Laid-Open No. 57-23261 and those shown in FIGS. 10 and 11.

That is, the lower end portion of the handle 1 is a circular holding portion 3 formed on the upper portion of a main body 2 which is divided into left and right parts.
When the handle 1 is clamped in the rear of the main body 2 and rotatable, and the handle 1 is raised upward, the handle 4 at the tip of the handle 1 is used for cleaning work, and after cleaning, the buckle 5 is unlocked to show the handle 1 As shown in FIG. 11, the main body 2 was rotated to the rear so as to reduce the total height and stored.

The diameter of the circular holding portion 3 is substantially the same as the width of the main body 2 in the front-rear direction. When the handle 1 is raised, it extends upward from the front surface of the main body 2 and the handle 1 is rotatably housed behind the main body 2. In the state, the handle 1 was slanted downward from the rear surface of the main body 2, and the tip of the handle 4 was in contact with the back surface of the main body 2.

[0006]

According to the above construction, when the handle 1 is rotated and stored, the storage space in the front-rear direction when standing up on the floor is larger than the handle 1 and the handle from the front end face of the floor suction tool 6. The distance to the bent portion of No. 4 was L, which was large.

Further, since the handle 1 projects rearward from the back surface of the main body 2 by the bending amount of the handle 4, the appearance is unsightly.

Regarding these, actual development of Japanese Utility Model Laid-Open No. 57-23261
The same applies to the device described in the publication.

Further, when the main body 2 is used, substantially the central portion of the handle 4, that is, the handle portion 4A is located in front of the central axis in the longitudinal direction of the main body 2, and the height of the handle portion from the floor surface is made constant. At this time, the angle between the main body 2 and the floor surface becomes small. When this angle becomes smaller, the weight moment of the product weight excluding the floor suction tool 6 acting as a fulcrum acting on the palm having the grip 4 is the horizontal distance from the floor suction tool 6 to the center of gravity position. Since the angle decreases and increases as the angle increases, the weight acting on the palm of the handle increases, which causes fatigue during use.

If the bending angle of the handle 4 with respect to the handle 1 is increased, the handle portion can be located near the central axis of the main body in the longitudinal direction, but in this case, the storage space L shown in FIG. 11 becomes larger. Will end up.

Further, the circular holding portion 3 which serves as a handle when the handle 1 is housed has a step formed between the main body side 2 and the handle 1 side and a circular shape which is difficult to fit in the hand, and thus is uncomfortable to use.

By making the diameter of the circular holder 3 larger, the shape can be made easier to fit in the hand, but in this case, the dimension in the front-rear direction becomes large and the storage space also becomes large.

Further, since the circular holding portion 3 also includes the internal wiring 8 led to the power switch 7 provided near the handle 4, another power switch is provided for use as a handy type. Since the power switch 7 is provided only in the vicinity of the handle 4 when used as a handy type when the handle 1 is stored, the power switch 7 is separated from the circular holding part 3 so that the power switch 7 can be turned on and off. Becomes very difficult.

A changeover switch 51 is provided on the rotation locus of the rotation stopper 25 to switch between the power supply switch A36 and the power supply switch B47.

Next, the operation and action of the above configuration will be described. When using the vertical vacuum cleaner 12, pull out the power cord 18 from the main body 11 and connect it to a power outlet, grasp the grip A22 with the hand, tilt the main body 11 backward, and turn on the power switch A36 to turn it on. At the same time when the blower is operated, the floor nozzle 16 is moved back and forth or left and right for use. Since the floor nozzle 16 is connected to the main body 11 so that it can be lifted up and down and rotated in the left and right directions, the floor nozzle 16 can be easily turned to the left and right by twisting the main body 11 to the left and right. The main body 11 is used by being twisted when cleaning the place where the connection port 15 hits the floor surface such as under the bed and there is no room in height.

After use, it can be stored upright in the corner of the room as it is, but by pulling the buckle 30 backward and removing the claw 31 from the stepped shaft portion 23 of the handle 21, the handle 21 can be rotated to the position shown in FIG. It can be stored by rotating like 3 and can be stored upright with increased stability or stored in a closet. Furthermore, by making the end portion of the handle 21 the stepped shaft portion 23, the strength of the shaft portion is improved and the rattling of the shaft portion can be prevented.

By the way, since the rotary sliding surfaces 29 of the handle 21 and the handle cover 19 are inclined toward the rear side of the main body 11 by about 8 degrees with respect to the central axis of the main body 11 in the longitudinal direction, the handle 21 is placed on the front surface of the main body 11. When the handle 21 is rotated in the direction of the floor nozzle 16, the rear surface of the handle 19 is separated from the front surface of the main body 11 by this angle. Therefore, the rotary sliding surface 29 does not protrude from the front end surface of the main body 11 and the handle 21 rotates. Can be stored. Therefore, the amount of protrusion of the entire handle 21 from the front surface of the main body 11 can be reduced.

Furthermore, since the rotary sliding surface 29 is inclined toward the rear side of the main body by about 8 degrees, the position of the handle A22 approaches the central axis of the main body 11. When the height of the handle A22 from the floor surface is constant during operation, the angle between the central axis of the main body 11 and the floor surface becomes larger than when the rotary sliding surface 29 is not inclined. As a result, when the floor nozzle 16 is rotated about the fulcrum, the weight of the main body excluding the floor nozzle 16 causes the handle A to move.
The weight moment acting on the palm having the hand 22 is reduced as the horizontal distance from the floor nozzle 16 to the position of the center of gravity becomes smaller as the angle becomes larger, and the weight load acting on the palm having the handle A22 is lightened.

Next, the inclination of the rotary sliding surface 29 and the handle 2
By bending the handle A22 with respect to 1, the central portion of the handle A22 is located near the A surface that divides the weight of the main body 11 in the front-rear direction into two, and as a result, the twisting torque when twisting the main body 11 left and right can be reduced, The load on the can be reduced.

Further, the rotary sliding surface 29 and the handle 2
1. Due to the combination of the bending angles of the handle A22, when the handle 21 is rotated and stored, as shown in FIG.
The gap between 1 and the main body 11 can be made substantially uniform and small.
As a result, it is possible to improve the appearance of the handle 21 when it is rotated and stored, and to effectively use the space above the floor nozzle 16 to reduce the storage space in the front-rear direction.

Further, when the handle 21 is rotated and stored, the hose 14 is disposed on the rear surface of the main body 11 opposed to the rotary stored position of the handle 21, so that the handle B35 is held while the handle 21 is rotated and stored. When using it as a handy type vacuum cleaner, the hose 14 can be removed from the connection port 15 regardless of the position of the handle 21 and an attachment can be connected to the end of the hose 14 to prevent the hose 14 from being used. There is no. Even if the hose 14 is provided on the side surface of the main body 11, the hose 14 can be used regardless of the rotation storage position of the handle 21.
In this case, in normal use, the hose 14 is
It tends to get out of the side and get in the way, which makes it inconvenient.

The power switch A is provided near the handle A22.
By providing 36 and pulling out the lead wire 37 to the main body 11 from the hole A38 at the center of the shaft portion, the lead wire 37 is not twisted due to the rotation of the handle 21, and the durability of the lead wire 37 is improved.

Further, the handle 21 and the handle cover 19 for rotatably accommodating the handle are composed of left and right parts respectively, and the left and right split surfaces A41 of the handle shaft portion and the left and right split surfaces B42 of the handle cover are displaced from each other. As a result, there is no catch on both split surfaces during use, and the usability is improved.

Further, since the recess B43 is provided on the front surface of the handle cover 19 facing the handle 21, even if a foreign matter enters between the front surface of the handle cover 19 and the handle 21, the foreign matter escapes to the recess B43. The rotation of the handle 21 can be kept smooth.

Further, a buckle 30 for fixing the handle 21 in the raised state is provided on the handle cover 19, and the handle 2
The concave portion A34 and the buckle claw portion 31 provided in the stepped shaft portion 23 of No. 1
Since the taper 44 is provided on the handle, there is no backlash between the recess A34 and the buckle claw portion 31, and there is no wobbling of the handle 21 at the time of use, and the usability is improved.

Next, FIGS. 7 to 9 show a second embodiment.
Since the rotation stopper 25 restricts the handle 21 from rotating to the left, the lead wire 3 pulled out from the power switch A36 provided near the handle A22 in the handle 21.
7 can be prevented from twisting.

Further, by making the shape of the end of the stepped shaft portion 23 of the handle 21 into a truncated cone shape, the pressure receiving area between the stepped shaft portion 23 and the bearing portion 24 in the rotational axis direction and the radial direction can be reduced. Therefore, the peripheral part of the rotating shaft can be downsized.

Further, the bearing portion 2 is provided on the front portion of the handle cover 19.

Further, a rib 49 is provided between the boss B48 provided in the stepped shaft portion 23 of the handle 21 and the end wall 23A of the stepped shaft portion 23 so as to connect them to each other. By providing the groove 50 on the shaft sliding surface, it is possible to minimize the deformation of the frustoconical shaft end portion 46 of the handle when a load is applied. Further, if the groove 50 is not provided, a sink mark is generated during the molding, and the hole diameter of the boss B48 becomes larger than a predetermined size, which tends to cause a tightening failure, but this phenomenon can also be suppressed. In addition, even if abrasion powder or the like is generated due to rubbing during rotary sliding, it escapes to the outer peripheral portion through the groove, and good rotary sliding can be maintained.

Further, the rotation stopper 25 of the handle 21
