DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view of a vertical vacuum cleaner according to an embodiment of the present invention, and FIG. 2 is a side sectional view of a main part thereof. In FIG. 1, 1 is a main body of a vertical vacuum cleaner, and 2 is a brush. As shown in FIG. 2, the main body 1 is provided with a cord reel 5 for winding the electric cord 4 by the action of a mainspring (not shown).

FIG. 3 is a bottom view of an AA cross section of the main body. In the figure, 6 is a roller that is an elastic member that is brought into contact with the outer wall surface (hereinafter referred to as the outer wall surface) 7 of the cord reel 5, and this roller 6 is a rotation stopping member for stopping the rotation of the cord reel 5. And is held by one arm (hereinafter, referred to as one arm) 8a of the two arms 8a and 8b of the brake arm 8 formed in a substantially L shape.

The roller 6 is rotatably held inside the brake arm 8 by one arm 8a. Further, the brake arm 8 is pivotally supported in the central portion so as to be horizontally swingable about a pivot shaft 9 as a fulcrum, and one arm 8a is biased toward the outer wall surface 7 by a spring (not shown).

When the electric cord 4 is pulled out for cleaning, the roller 6 rotates while being brought into contact with the outer wall surface 7 of the cord reel 5 by the brake arm 8. However, after pulling out the electric cord 4, the brake arm 8 is rotated. The roller 6 is pressed against the outer wall surface 7 by 8 and the roller 6 is sandwiched between the outer wall surface 7 and the inner wall (hereinafter referred to as the inner wall) 8c of the brake arm 8 so that the roller 6 cannot rotate.

Therefore, the cord reel 5 cannot rotate,
The electric cord 4 is held in the pulled-out state. When winding the electric cord 4, the brake arm 8 rotates the roller 6 in a direction to release the pressure contact of the roller 6.

On the other hand, another arm (hereinafter referred to as another arm) 8b of the brake arm 8 is provided with a taper portion on a side surface which does not face the outer wall surface 7 in a direction in which the inner wall 8c extends downward from above. A slider 11 having a taper formed in a direction narrowing from the upper side to the lower side is fitted in a space between the side surface and the wall member 10 provided upright to face the side surface.

The armature 11 is biased upward by a coil spring 12 and one end of a flexible wire 13 is fixed to the lower end thereof. When the electric cord 4 is wound up, the flexible wire 13 pulls the wire downward to pull it up against a wall. The brake arm descends along the member 10 and the other arm 8b is pressed against the outer wall surface 7 side against the urging force of a spring (not shown) in accordance with this descending, whereby the brake arm is released in the direction of releasing the contact. 8 is configured to rotate.

On the other hand, the other end of the flexible wire 13 passes through the cable 14 and is fixed to the front portion of the brush portion 2 in a tensioned state. Here, the reason why the flexible wire 13 is used is that the brush portion 2 is rotatably provided and can follow the movement of the brush portion 2.

A pressing roller 15 is provided on the upper surface of the stretched flexible wire 13 so as to come into contact with the flexible wire 13. further,
As shown in FIG. 1, the pressing roller 15 is in contact with the lower end of a cord take-up button 16 projecting near the upper end of the brush portion 2 so that the user can operate it with his / her foot.

Next, the operation of winding the electric cord of the vertical vacuum cleaner thus constructed will be described.

Since cleaning is performed using a vertical vacuum cleaner,
First, the user pulls out the electric cord 4 from the vertical vacuum cleaner body 1 against the spring pressure of the mainspring, and in conjunction with this, the cord reel 5 rotates counterclockwise as shown by the arrow in FIG. To do. At this time, the roller 6 is in contact with the outer wall surface 7, but since the roller 6 rotates freely, the cord reel 5 can rotate and the electric cord 4 can be pulled out freely. it can.

On the other hand, when the user releases his hand after pulling out the cord reel 5 by a necessary amount, the cord reel 5 tries to rotate clockwise by the force of the spring to open, and at this time, the roller 6 and the outer wall surface. A frictional force is generated between 7 and.

Here, this frictional force tends to rotate the roller 6, and since the diameter of the roller support shaft 8d is smaller than that of the shaft supporting hole 8e, the roller 6 is moved to the inner wall 8c side. It acts to let you. Therefore, the roller 6 contacts the inner wall 8c inside the brake arm 8, and
Since it is held so as to be sandwiched between the inner wall 8c and the outer wall surface 7, it hardly rotates.

Therefore, the cord reel 5 is prevented from rotating and the electric cord 4 is not wound up. When the electric cord 4 is pulled out in this manner, the moving element 11 is held by the coil spring 12 as shown in FIG.

Eventually, the cleaning is completed, and the electric cord 4 pulled out from the vertical vacuum cleaner main body 1 is stored in the main body 1. Therefore, the user has a cord take-up button provided on the upper surface of the brush portion 2. When the foot 16 is stepped on, the push-down roller 15 descends in conjunction with this, and the push-down roller 15 pushes down the flexible wire 13 in contact therewith. At this time, the roller surface of the pressing roller 15 comes into pressure contact with the flexible wire 13, and the flexible wire 13
Does not scratch the surface.

When the flexible wire 13 is pushed down, the movable element 11 to which one end of the flexible wire 13 is fixed moves down along the wall member 10. Then, as the armature 11 descends, the other arm 8b is pressed against the outer wall surface 7 side and one arm 8a rotates in the direction opposite to the pressure contact direction of the roller 6, and as shown in FIG. The contact of the cord reel 5 with the outer wall surface 7 is released.

As a result, the cord reel 5 becomes rotatable and is rotated clockwise by the force of the mainspring to open, so that the electric cord 4 can be wound up. After this, remove your foot from the cord wind-up button 16 and move the mover 1
1 is moved to the position before being lowered by the coil spring 12, and the pressing of the armature 11 against the other arm 8b is released. As a result, the one arm 8a is again rotated by the spring in the direction of coming into contact with the outer wall surface 7, and the roller 6 comes into contact with the outer wall surface 7.

In this manner, the electric cord 4 can be stored by stepping on the cord winding button 16 provided on the brush portion 2.

[0027]

As described above, according to the present invention, the foot switch is operated by using the foot, the pressure contact releasing member is lowered through the flexible wire, and the rotation restraint by the rotation restraining member of the cord reel is released. , The electric cord can be wound by rotating the cord reel. This allows the electric cord to be wound up without bending the waist.
