Description

[Detailed description of the invention] The present invention relates to a record stand that is used when cleaning or removing static electricity from a record using a self-propelled or manual record cleaner or static eliminator. By making the spindle freely rotatable, the record cleaner and static eliminator can be smoothly rotated over the record.

In recent years, record cleaners and static eliminators that use self-propelled drive wheels to clean and eliminate static electricity while rotating around a spindle above the record disc have gradually become popular due to their ease of handling. I've been doing it.

By the way, such cleaning and static elimination work is carried out by placing and setting the record cleaner or static eliminator on the record by inserting a spindle insertion hole formed in the record cleaner or static eliminator into a spindle set up on the stand. However, if the spindle is fixed on a stand, when the record cleaner or static eliminator rotates around the spindle,
The sliding friction between the inner circumferential surface of the spindle insertion hole and the outer circumferential surface of the spindle increases, resulting in a large load for self-propelled turning. Of course, this sliding friction is not limited to those that are self-propelled and turn, but also applies to those that are driven directly by hand around a spindle.

Therefore, the present invention has been developed with these points in mind, and by installing the spindle rotatably upright on a mounting table, the sliding friction between the inner circumferential surface of the spindle insertion hole and the outer circumferential surface of the spindle is reduced. Make it smaller;
To provide a record stand that allows a record cleaner and a static eliminator to smoothly rotate on their own over the record.

Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a perspective view of the record stand, Fig. 2 is an exploded perspective view of the main parts, and Fig. 3 is a partially cutaway side view during use.The main body 2 of the record stand 1 is made of synthetic resin. It is a long box body made of aluminum, and its top surface consists of a base plate part 2 ₁ that supports the label part of the record disc 3, a lower plate part 2 ₂ that corresponds to the recording part, and an edge plate part 2 ₃ that supports the peripheral non-recording part. The center hole of the record disc 3 and the spindle insertion hole 4' of the static eliminator 4 as an embodiment of the record disc cleaning device are provided in the center of the substrate part ₂₁ .
A spindle 5 for fitting is provided upright.

The spindle 5 is made of a conductive material such as brass or copper, and is rotatably installed in a mounting hole 6 formed in the base end ₂₁ . A discharge body 7 in which a large number of carbon brushes 7' are embedded is vertically installed. 8 is Watsusha.

A pair of leg rods 9 ₁ , 9 ₂ made of synthetic resin are housed on both longitudinal edges of the main body 2 , and one end of the leg rods 9 1 , 9 2 is connected to the bottom of the base plate 2 ₁ by pins 10 ₁ , 10 ₂ . The legs are pivoted on the sides, and can be rotated 120 degrees around pins 10 ₁ and 10 ₂ to open the legs, as shown by phantom lines. In addition, each leg rod 9 ₁ ,
Protrusions 11 ₁ and 11 2 for supporting the peripheral non-recording portion of the record disc 3 are protruded from the tip of 9 ₂ , and the upper surfaces 11 ₁ ′ and _{11 2 ′} are uneven.
It is designed to be rotated by hooking your fingertips.

The static eliminator 4 includes a discharge electrode plate 1 that generates corona discharge.
2 and a cathode plate 13 are built-in, and the cathode plate 13
is connected by a conductive wire 14 to a contact piece 15 disposed above the spindle insertion hole 4'. 1
6 is a drive wheel for self-propulsion, and 17 is a switch button.

The main stand 1 has the above-mentioned configuration. When in use, the legs 9 ₁ and 9 ₂ are rotated to open the legs, and when the record 3 and the static eliminator 4 are placed and set, the contact piece 15 is attached to the spindle 5. touches the top of the Next, when the switch button 17 is pressed, the drive wheel 16 rolls on the record 3, and the static eliminator 4 rotates on the record 3 about the spindle 5. At this time, the inner circumferential surface of the spindle insertion hole 4' comes into sliding contact with the outer circumferential surface of the spindle 5, but since the spindle 5 is rotatably installed, as the static eliminator 4 rotates,
The spindle 5 can also rotate in the same direction.
Therefore, the sliding friction is extremely small, and the static eliminator 4 can smoothly rotate on its own over the record 3. Furthermore, a record disc 3 is provided in the gap between the inner peripheral surface of the spindle insertion hole 4' and the outer peripheral surface of the spindle 5.
It is common for the static eliminator 4 to become unable to rotate on its own due to large particles of dirt on top floating up and entering the static eliminator 4.
Since the spindle 5 is rotatably installed, the static eliminator 4 will not become unable to rotate on its own even if large particles of dirt get into it.

Now, along with the self-propelled rotation of the static eliminator 4, corona discharge occurs between the discharge electrode plate 12 and the cathode plate 13,
The generated ions are blown onto the record 3,
The static electricity charged on the record 3 is neutralized and removed.

By the way, if the ions generated by the corona discharge remain in the static eliminator 4, they will have an adverse electrical effect, such as causing the electrical system built in the static eliminator 4 to malfunction. However, in the above configuration,
The staying ions are quickly captured by the cathode plate 13 and passed through the conductive wire 14, the contact piece 15, and the spindle 5 to the discharge body 7.
and is neutralized and removed by an air discharge generated near the tip of the carbon brush 7'.

4 and 5 are a perspective view and a cross-sectional view of main parts of another embodiment of the present invention in a state of use, in which the main stand 18 is also a long box made of synthetic resin, and the upper surface of the main body are the base plate part 19 ₁ , the lower plate part 19 ₂ , and the edge plate part 19 ₃
A circular recessed part 20 is formed in the substrate part ₁₉₁ , and a central hole 20 is formed in the center of the recessed part 20.
1 is formed. A disk-shaped plate 22 is separately formed to be fitted and placed in the recess 20, and a conductive spindle 23 is rotatably erected at the center thereof. Further, at the lower end of the spindle 23, a large number of conductive rings 2 are provided as discharge means.
A conductive chain 24 for grounding formed by connecting 4' in a chain is vertically installed, and the mounting base 18 is connected to the base 2.
When placed on the base 25, the conductive chain 24
It is designed to be grounded to.

The main mounting stand 18 is constructed as described above, and as the static eliminator 4 rotates, the spindle 23 also rotates in the same direction, so the sliding friction with the inner peripheral surface of the spindle insertion hole 4' is extremely small. Static eliminator 4
can smoothly rotate on its own over the record 3. Further, the ions remaining in the static eliminator 4 quickly leak out to the base 25 through the conductive chain 24.

Although each of the above embodiments has been described using the static eliminator 4 as an example, it goes without saying that it can also be applied to a record cleaner.

As explained above, the present invention is based on the spindle 5, which is installed upright on the table 1, 18 on which the record is placed.
23 is fitted with a cleaning device equipped with a cleaning means inside, and the cleaning device 4 is rotated around spindles 5 and 23 to perform cleaning. The mounting tables 1 and 18 are made of synthetic resin, and the spindles 5 and 23 erected on the mounting tables 1 and 18 are made of a conductive material.
A discharge means is provided on the lower end side of the spindle 5,
Since the spindles 5 and 23 are rotatable on the mounting tables 1 and 18, the spindles 5 and 23 can be used as discharge circuits insulated from the mounting tables 1 and 18.
Since the spindles 5 and 23 are rotatable, the sliding friction between the static eliminator and the like is extremely small, and the contact force between the static eliminator and the spindle 5 and 23 is increased to form an electric path for discharge. It is possible to turn smoothly even if the force is increased.
