Description

DETAILED DESCRIPTION OF THE INVENTION A) Industrial Application Field The present invention relates to an electric blower, an electric blower, a suction port (1), and a rotary brush. Regarding machines.

(2) Conventional technology In this type of vacuum cleaner, when the operating handle is held perpendicular to the main body of the vacuum cleaner, the brush rotates in the same place on the surface to be cleaned such as a carpet, causing damage to the surface to be cleaned. In order to prevent this, a wheel is provided that moves in and out in conjunction with the operating handle, and this wheel is constantly biased upward by a coil spring (see USP 3654.661 specification and drawings).

However, this conventional example has the disadvantage that when the axle is pulled, the coil spring stretches and loses its springiness, resulting in poor durability, as well as a complicated structure and a high mast.

C) Problems to be solved by the invention The present invention has been made in view of the above points, and when moving furniture etc. during cleaning, the front part of the main body rises above the floor by tilting the operating handle. This prevents the carpet surface from being damaged even when the rotating brush is rotating.

2) Means for Solving the Problems The present invention provides a pair of wheels supported by an axle at the rear of a vacuum cleaner body equipped with an electric blower and a rotating brush at the suction port, and a pair of wheels supported by an axle are attached to the axle via a support arm. The operating handle is rotatably supported, and the handle is held bare at a predetermined position by a handle switching lever. This problem is solved by making the center of gravity of the entire vehicle be located between the axle and the sled when the sled comes into contact with the floor during use.

e) Push the operating handle switching lever to release the locked state of the operating handle, and when the operating handle is in the tilted usage state, when you release your hand from the handle, the claw at the tip of the handle will lock onto the handle switching lever. It tilts until it catches the stopper and stops. In this state, the weight of the handle moves rearward, so the entire center of gravity also moves rearward, shifting the center of gravity between the wheels and the sled. ) and a bottom plate (5) forming a horizontally elongated suction port (4), and an electric motor (
The blower (7) and the electric motor (6) are driven from No. 61.
) houses a rotating brush αα connected to the rotating shaft (8) of the brush via a belt (9). aυ0 is a wheel disposed at the rear of the vacuum cleaner main body (1), and a rod-shaped operating handle (toward) having a grip part αΦ at the tip is rotated on the axle shaft (2) of the wheel via a bifurcated arm member α3. It is installed so that it can move freely.

(to) is a ventilated nest dust bag whose opening is the main body (
1) It is removably connected to the intake passage α mark containing the blower (7) formed inside, and the end thereof is latched to the lower part of the grip part I of the rod-shaped operating handle (to) via the coil spring α9. There is.

The rock has one end pivotally supported by a support shaft (shaft) in front of the axle (1), and the other end has a pedal section (1).The handle is a 1-handle switching lever, and the lever has a relief hole through which the axle (2) is inserted. and a stopper piece that is appropriately engaged with the first and second claw parts (to) formed at the tip of the arm member (to).
is provided.
1) The penalty is a sled part provided at the rear end of the vacuum cleaner body (1), which is a sled part that is used when the operating handle (to) is tilted and the user's hand is removed from the handle Q5). Wheels (111 (11)
It is supported together with 1.

The device is a microswitch that controls the electric motor (6) by coming into contact with and separating from the arm member (6) as the operating handle (6) rotates, and is OFF when the operating handle (6) is stored upright, but when the operating handle (6) is in an upright state. It is turned on when in use. 3 is a buffer band attached to the peripheral side of the vacuum cleaner body (1). - In the above configuration, when the operating handle (19) is stored in an upright position, the entire center of gravity is forward of the axle (2).The stopper piece (■) of the handle switching lever (■) is connected to the first claw (toward) of the arm member αj. At the same time, the microswitch comes into contact with the arm member a3 and is turned off, so the electric motor (6) is stopped, and accordingly, the rotating brush α1 and the feed Kfi l?) are also stopped. .

Then, step on the pedal part (support) and push down the handle switching lever ■ to unlock the operating handle (151), and when you release your hand from the handle (to) in normal use condition, the handle (to) becomes an arm member. The second claw part (5) rotates until it hooks on the stopper piece (■) of the handle switching lever (■), tilts, and stops.

In this state, the weight of the handle moves rearward, so the entire center of gravity also moves rearward, and the center of gravity moves between the axle and the sled.
The vacuum cleaner main body (1) is supported by the wheels (11) Ql) and the sled surface, and as the rotating brush leaves the floor ■, the operation handle (to) moves and the micro switch ■ By interlocking, the microswitch is turned off when the handle (to) is placed upright, and the microswitch is turned on when the handle (to) is tilted.
If the floor 4 hat ζ is left in this state, the rotating brush 1α will automatically move away from the floor surface ■, thereby preventing damage to the carpet floor surface.

g) Effects of the Invention Since the present invention is constructed as described above, there is no damage to the carpet floor surface etc. even if the cleaning is interrupted temporarily, and the structure is easy to handle due to the spacing, making it practical. We can provide an excellent upright electric cleaning rock.
