Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a canister type vacuum cleaner.

BACKGROUND ART Conventionally, vacuum cleaners of this type have had a structure as shown in FIG. 8, for example.

That is, a pedal 1 having a rotating shaft 1a approximately in the center and integrally formed with a brake petal portion 1b and a switch petal portion 1c is provided on the upper surface of the main body 2, and a bearing portion 3 corresponding to the rotating shaft 1a is provided. A petal spring 4, which is formed as a part of the main body 2 and biases the operation of the petal 1, is provided approximately at the bottom of the center of the petal 1, and brake levers are provided at the bottom of both sides of the petal 1 so as to operate in conjunction with the petal 1. 5 and a switch 6, and generally had an exhaust port 7 on a part of the outside of the main body 2, completely unrelated to the petal 1, and an exhaust filter 8 inside the exhaust port 7. .

Problems to be Solved by the Invention In such a conventional configuration, since the rotating shaft 1a is in a fixed position, when either the brake pedal part 1b or the switch petal part 1c is pressed to operate, the other one does not lift up. I had a problem with it getting hot. Also, if you press near the rotation axis 1a,
There was a problem that the pedal 1 became difficult to operate, or in some cases could not operate.

This invention solves these problems,
An object of the present invention is to provide a vacuum cleaner having a petal with good operability so that even when one side of the petal is pressed, the other side does not lift up, and the operation can be performed smoothly no matter which position is pressed. .

Means for Solving the Problem In order to solve this problem, the present invention provides a pedal on the main body that is biased upwardly by a spring or the like and can move up and down, and a brake pedal part and a switch pedal are attached to both ends of this pedal. In addition, when the brake pedal at one end is pressed down, the cord reel brake lever is linked to release the cord reel brake, and when the switch petal at the other end is pushed down, the main body switch is linked to switch between on and off. The petal is configured to be able to move, and is provided with engaging portions near the four corners of the petal that engage with the main body in a vertically movable manner.

Effect With this configuration, when one end of the petal is pressed,
Of the four engaging parts, only the two on the pushed side move downward, and the other does not move. Therefore, when one end is pushed as in the conventional example, the other end does not lift up. Also, if we consider the case where the part near the center of the petal is pressed, in this case all four engaging parts will move downward,
Unlike the conventional example, there is no problem of poor movement or no movement. Furthermore, if we consider the case where the rear end of the petal is pressed, in this case, the 2nd part of the rear end
The engaging portions at the locations move downward, causing the petals to move. As a result of the above, the petal of the present invention operates smoothly no matter where it is pressed, and there is no problem such as the other end lifting up when one end is pressed, making it possible to improve operability.

Embodiment Hereinafter, the drawings (first
This will be explained based on FIGS.

In the figure, 10 is the outside of the main body that houses the motor 11 and cord reel 12, and 13 is the dust collection chamber 1.
4, a dust collection chamber lid for taking in and taking out the dust collection bag 15; 16, an intake port gasket attached to the intake port 17 to maintain tightness with the hose and the dust collection bag 15; 18; 19 is an air protector for taking in outside air and preventing overheating when the intake port 17 is sealed, and 19 is an intake filter made of urethane foam to prevent fine dust from entering. 2
0 and 21 are rubber front support rubber and rear support rubber that hold the motor 11 in a vibration-proof manner;
22 is a motor cover that holds the rear part of the motor 11, 23 is a primary exhaust port provided outside the main body and at the top of 10, and 24 is located between the primary exhaust port 23 and the petal 25 above it. Exhaust filters made of urethane foam, 25a and 25b are brake pedal parts and switch petal parts that constitute part of the petal 25, 25c is a secondary exhaust port provided in the petal 25, and 25d and 25e are the petal 25.
Claws and protrusions, 26, provided at the four corners of each petal portion 25a, 25b to face each other, respectively.
and 27 correspond to the claw part 25d and projection part 25e of the petal 25, and a claw part receiver and a protrusion part receiver which restrict the operating range thereof; 28, a petal spring which urges the petal 25 upward; and 29, a push button type switch. , 30 is a brake lever that holds the brake roller 31, 32 is a caster, and 33 is a roller. Note that the petal 25 has claw portions 25 at the four corners.
d, the claw part 2 so that it can move up and down with the protrusion 25e.
5d is formed to be elongated in the vertical direction and engages with the claw portion receiver 26 (see FIG. 7), and the protrusion portion 25e is engaged in the protrusion portion receiver 27 in the form of a vertical groove that is elongated in the vertical direction. (See Figure 6).

In the above configuration, the dust-containing air taken in from the intake port 17 is filtered by the dust collection bag 15, passes through the intake filter 19 and the motor 11, and then passes through the primary exhaust port 23, the exhaust filter 24, and the secondary exhaust port. 25
It is discharged to the outside through c. The switch is turned on and off by pressing the switch petal portion 25b, and the cord is wound up, that is, the brake lever 30 is released by pressing the brake pedal portion 25a. As shown in FIG. 6, these petal parts are operated by moving downwardly only two of the four claw parts 25d and projections 25e on one side. Furthermore, even if the rear end of the pedal 25 is pressed as shown in FIG.
5b operation is possible. Therefore, no matter which part of the petal 25 is pressed, the petal operation is smooth, and there is no problem such as when one end is pressed and the other end lifts up.

Effects of the invention As described above, according to the invention, by restricting the vertical movement of the petal near the four corners, the operation can be performed smoothly no matter where you press the petal, and when you press one end, the other end There is no adverse effect such as that caused by floating, and operability can be improved.
