Description

[Detailed Description of the Invention] This invention relates to a self-propelled record cleaner that is pivotally connected to the spindle of a turntable and runs over the record around the spindle.

With conventional record cleaners, you have to hold the record with one hand, which can leave marks on the record or cause the record to accidentally slip and break. Since the entire circumference is wiped while changing the amount of water, uneven wiping tends to occur.

For this reason, one end of the cleaner body is already rotatably pivoted to the spindle of the turntable of the record player, and while the cleaner body runs over the record centering on the spindle, the roller brush supported by the cleaner body is used to move the cleaner body over the record. A so-called self-propelled type that collects dust has been proposed.

By the way, in such a self-propelled record cleaner, it is required that the rotational force of one motor serves as the driving force for the driving wheels and the rotational driving force for the roller brush, thereby minimizing the weight burden on the record. It is necessary not only to prevent the disc from being damaged by the wheels, but also to prevent the user from feeling anxious that the record disc will be damaged by the wheels.

This idea was made in view of the above circumstances, and consists of a belt that transmits the rotational force of the motor to the roll brush via a reduction pulley, which is hung around the outer circumferential surface of the driving wheel, and this belt is configured as a running drive belt. It is an object of the present invention to provide a self-propelled record cleaner that can simplify the rotary drive system and can be operated by itself without giving the user a sense of anxiety that the record will be damaged.

An embodiment of this invention will be described below with reference to the drawings.

1 and 2, reference numeral 1 denotes a cleaner body made of synthetic resin or the like in the shape of a long box, consisting of an upper case 2 and a lower case 3, and located on one end 1a side of the cleaner body 1. A power supply battery 4 and a motor 5 driven by the battery 4 are mounted inside the lower case 3, and a roll brush 6 is supported on the lower case 3 at the other end 1b side. , - of the outer periphery of this roll brush 6
portion is exposed from the bottom wall of the lower case 3 (see Fig. 3).

Reference numeral 7 denotes a shaft hole that is fitted and pivotally supported by a spindle 9a of a turntable 9 on which a record disc 8 is placed, and is located at one end 1a of the cleaner main body 1 and formed in the lower case 3.

The reason why heavy objects such as the battery 4 and the motor 5 are placed on the one end 1a side of the cleaner body 1 is to set the center of gravity of the cleaner body 1 at the center of travel, thereby stabilizing the travel. be.

10 is a driving pulley fixed to the rotor shaft 11 of the motor 5, 12 is a reduction pulley fixed to the shaft 13 of the roll brush 6, and 14 is a support member 15 within the cleaner body 1.
It is a driving wheel for running that is rotatably supported by 16.

On the outer circumferential surface of the drive pulley 10 and the outer circumferential surface of the driving wheel 14,
A belt 18 having protrusions 17 for preventing slipping is hung, and this belt 18 is configured as a running drive belt.

Furthermore, the reduction pulley 12 is rolled down onto the belt 17, so that the roll brush 6 is rotated.

When the rotation speed of the motor 5 is 5.00OR, P, M,
Roll brush 6 rotated via the reduction pulley 12
It is preferable to set the rotational speed of the driving wheels 14 to about 3.00OR, P, and M, and the rotational speed of the driving wheels 14 to about 200R, P, and M, respectively.

19 is a slave shaft, 20 is a dust collection chamber provided in front of the roll brush 6 in the rotating direction, and 21 is a lid body that opens and closes the dust collection chamber 20 and has a ventilation hole 22.

23 is a lid for holding the battery, and 24 is an elastic material such as a sponge that suppresses the vibration noise of the motor 5 when the upper case 2 is covered, and also has the function of preventing rattling.

In the above structure, the spindle 9a of the turntable 9 is inserted into the shaft hole 7 of the cleaner main body 1 and set as shown in FIG. 3.

In this state, turn on the W switch (not shown) and motor 5
When activated, the driving pulley 10 rotates in the direction of arrow a as shown in FIG. .

Since the reduction pulley 12 rotates in the direction of arrow C due to the rotation of the belt 18, the roll brush 6 also rotates in the same direction.

Therefore, the dust on the record 8 is bounced up by the tip of the roll brush 6 that rotates against the direction of travel, and at the same time is carried by the air flow generated by the rotation of the roll brush 6 and collected in the dust collection chamber 20. taken.

Here, the traveling drive system and the rotational drive system of the roll brush 6 have a simple configuration that utilizes the rotational force of one motor 5, and the rotational force is also transmitted through a belt 18 hung around the drive pulley 10. Since the belt 18 is used as a driving belt, there is no noise like a gear mechanism, and the belt 18 is hung around the outer circumference of the driving wheel 14, so there is a risk of damaging the top of the record 8 since the belt 18 acts as a tire. You can run it without any problems.

By the way, as shown in FIG. 5, the support shaft 25 of the driving wheel 14 is attached to the bearing portion of the supporting member 16 located on the shaft hole 7 side among the supporting members 15 and 16 of the driving wheel 14 in the direction in which the belt 18 is hung. A bearing piece 26 that elastically resists the movement (in the direction of arrow d) is integrally made of synthetic resin or the like.

This is because even if the support shaft 25 of the driving wheel 14 is not set toward the shaft hole 7, the bearing piece 26 is elastically deformed by the tensile force of the belt 18 at the same time as the driving wheel 14 is running, so that the support shaft 25 is not set toward the shaft hole 7.
5 is made to face the shaft hole 7, that is, the center of travel, and this prevents the driving wheels 14 from shifting laterally during traveling in the circumferential direction, allowing the above-mentioned traveling to be carried out without difficulty.

Of course, the support shaft 27 of the slave shaft 19 is also directed toward the center of travel to prevent lateral displacement during travel.

As described above, this invention has a belt that transmits the rotational force of the motor to the roll brush via the reduction pulley and is hung around the outer circumferential surface of the driving wheel to form a running drive belt, which simplifies the configuration and records records. It is possible to provide a self-propelled record cleaner that does not cause damage to discs.
