To explain the above condition using Fig. 2, a washer 4 is inserted under the turntable clamp screw 2 to prevent the surface of the turntable 3 from being scratched when the turntable clamp screw 2 is tightened. .

The turntable 3 still has a hole 3a through which the turntable clamp screw 2 passes.

Then, the turntable 3 is operated by a cover 5 with the record player unit 10 placed over the cover 1a.
As shown in the cross-sectional view of FIG.
It is fixed to the record player unit 1 in a lifted state so that a gap a can be secured between the record player unit 1 and the record player unit 1.

Additionally, the record player unit 1 is also provided with a device for transporting the record player unit 1 while being fixed to a stereo device.

In FIG. 1, the panel clamp of the record player unit 1 is indicated by 7. The role of the panel clamp is to fix the record player unit 1 and the table board 12 of the stereo device until it is delivered to the user so that the record player unit 1 is not damaged by vibration during transportation, and also to fix the record player unit 1 and the table board 12 of the stereo device to the user. When using the record player, it has the role of preventing the record player unit 1 from being lifted so that the person does not touch the electrical wiring of the stereo device.

The panel clamp screw 7 is screwed into the screw hole of the record player unit 1, but at this time, a washer 9 is inserted to prevent the surface of the record player unit 1 from being scratched.

The table board 12 has a hole 12 through which the panel clamp screw 7 passes.
A is formed in a dimensional relationship with the straight part 7b of the neck crane cinere to ensure a gap.

There is a groove 7a in the lower part of the neck cleaner. Now, insert a washer 10 with a diameter larger than the hole 12a of the table board 12 into the groove 7a and insert it into the groove 7a. By fixing the retaining ring 11, when the gunnel clamp screw 7 is raised in the direction of arrow C in FIG. The screw boss 1b contacts the table board 12, and the record player unit 1 and the table board 12 are fixed.

Furthermore, when the user uses the record player,
By screwing in the panel clamp screw 7 from the above-mentioned state (the state in which the gunnel clamp screw 7 is screwed up), a gap is created between the one shoe 10 and the table board 12, and furthermore, the record player unit 1 is attached to the cushion spring. 13 from the table board 12, a gap is created between the panel clamp Nelpos 1b and the table board 12, and a gap is also created between the straight part 7b of the panel clamp screw 7 and the hole 12a of the table board 12. Can be secured. In this way, the record player unit 1 is in contact with the table board 12 only through the cushion spring 13, so that the cushion spring 13 can cut off external vibrations necessary when playing a record.

In addition, from this state, even if you try to lift the record player unit 1, the washer 10 for preventing it from being pulled out is attached to the table board 12.
Since it is larger than the hole 12a, the user's hand will not get caught and touch the dangerous part.

When actually used, the turntable 2 and spacer 5 are removed, as shown in FIG. 4.

In addition to the above-described type of panel clamp screw 7, there is also a type shown in FIG. 5.

That is, as shown in FIG. 5(A), it is composed of three parts: a screw 14, a washer 15, and a clamp 9-16. After inserting the washer 15, the clamper 16 is attached to the screw 14.
5 (Fig.
As shown in B) and (C), it is rotated in the direction of the arrow to penetrate the hole 12a of the table board 12, but is prevented from being removed.

The conventional example has been explained above, but this method requires parts such as screws for the turntable clamp and the record player unit clamp, and the user has to remove the turntable's flange screws and spacer when in use. There was a risk that the item would be lost if re-transported.

The flange screws for the record player unit had to be placed on the outside of the turntable, which was an unsightly design.

The present invention solves the above-mentioned drawbacks and provides a fixing device for transporting a record player that is inexpensive and extremely easy to use. An embodiment of the present invention will be described below with reference to the drawings.

``First, the present invention will be explained in detail. FIG. 6 is a plan view of the entire record player unit using the transportation fixing device of the present invention.

The position of the clamp screw 17 is provided inside the turntable 2°.

FIG. 7 is a partially enlarged view of the turntable 200.

FIG. 8 is a perspective view showing the structure of an embodiment of the present invention. At the lower part of the screw head of the clamp screw 17, there is a detent 18 which is rotatably assembled with the Franz 0 screw 17 by processing the heel of the clamp screw 17 or the like. Grooves 21a and 21b that fit into the neckline 19 and the turntable 20, respectively
A clamp ring 21 is inserted into the upper straight part 17a of the clamp screw 17 so that it can rotate and slide up and down, and by fitting the retaining ring 22 into the groove 17b provided at the lower part of the upper straight part 17a. Extraction has been stopped.

- The sensor 19 has a screw hole 19a that engages with a threaded portion 17c provided at the bottom of the clamp screw 17, and a clamper 21 is provided on both sides of the screw hole 9a.
The second protrusion 19b that engages with the groove 21b is the remaining part.

Further, the turntable 20 has an elongated hole 20a through which the detent 18 passes and which can still engage with the groove 21a of the clamper 21.
is profitable.

On the other hand, a driving nut 24 having a screw hole 24a that engages with the threaded portion 17c of the clamp screw 17 is fixed to the table board 23 of the stereo device on which the record player unit having the transportation fixing device of the present invention is mounted. Further, this driving nut 24 is provided with an eave.

Next, the present invention will be explained in detail with reference to FIGS. 9(A) to 9(D).

In FIG. 9(A), the clamp screw 17 is
It is screwed into and penetrates the screw hole 19a of No. 9, and assembled with the retaining ring 22 and the upper part of the screw hole 19a in contact with each other.

25 is a turntable shaft, and 26 is a cushion spring for isolating the panel 19 from external vibrations.

First, a method will be described when it is necessary to fix and transport the turntable 20 and the A-wall 19 as a record player unit.

In the past, record player units and stereo devices were often produced in separate factories, and the record player unit was transported to the stereo device manufacturing factory and assembled to complete the entire system.

When transporting this record player unit, it is necessary to fix the turntable 20 and the panel 19 without causing any damage.

In FIG. 9(B), pull up the clamp screw 17 in the direction of the arrow to connect the screw part 17c and the screw hole part 19 of the panel 19.
Engage with a.

At this time, the detent 18 is raised together with the clamp screw 17 along the long hole 20a of the turntable 20.

Further, when the clamp screw 17 is screwed up to a certain extent, the clamp 21 is rotated 90 degrees to fit the grooves 21a and 21b into the protrusion 19b of the panel 19 and the elongated hole 20a of the turntable 20, respectively. .

At this time, the turntable 20 controls the clamper 21.
□Since the thick portion 1' between the grooves 21a and 21b is lifted up, there is a gap with the turntable shaft 25.

Further, since the retaining ring 22 pushes up the upper surface of the clamper 21, the clamper 21 is fixed to the panel 19 via the protruding portion 19b of the /4' flannel 19.

Further, since the detent 18 passes through the elongated hole 20a of the turntable 20, the turntable 20 can only move by a small gap between the detent 18 and the elongated hole 20a when it is lifted. Even if transported in this condition,
The weight of the turntable 20 is not applied to the turntable shaft 25 and can be safely transported.

Next, the case where the record player unit is fixed to the table board of the above-mentioned stereo system will be explained.

In FIG. 9(C), the panel 19 is placed on the table board 23. At this time, a driving nut 24 is fixed to the table board 23 at a position opposite to the clamp screw 17. now,
In the state shown in Fig. 9 (F3), tighten the clamp screw 17 by arrow B.
Screw it in the direction. Then, the threaded part 17c and the slotted hole 24a of the driving nut 24 are screwed together, and the entire flannel 19 is fixed with the lower part of the threaded part 19a and the head of the driving nut 24 in contact with each other. At this time, the detent 18 has descended together with the clamp screw 17 and is in contact with the crank 4'21, so the relationship between the turntable 20 and the turntable shaft 25 maintains a gap.
The rotation stopper 18 and the elongated hole 20a of the turntable 20 are still closed.
Since the relationship remains as shown in FIG. 9(B), the record player unit and the stereo device can be safely sent without being damaged during transportation.

Furthermore, with reference to FIG. 9 (■), a situation in which a user obtains this stereo apparatus and actually uses it will be explained. Loosen the clamp screw 17 in the direction of arrow A, create a gap between the rotation stopper 18 and the clamp groove 21, and then tighten the clamp screw.
Rotate groove 21 90 degrees 'sq, groove 21a' + 2 l
b, the elongated hole 20a of the turntable 20, and the panel 1
By releasing the engagement with the protrusion 19b of 9, the clamp 21 falls to the center ring 22. Then, tighten the clamp screw 17 further until the tip of the clamp screw 17 contacts the bottom of the driving nut 24. Then, first, turntable 2
0 and the crankshaft 21 disengage, the turntable 20 becomes in a usable state with no gap between the turntable shafts.

In addition, the Zenel 19 is connected to the table board 2 by the cushion spring 26.
3, the threaded part 19a of the flannel 19 is in a floating state.
Since there is a gap between the lower surface of the drive nut 24 and the upper surface of the driving nut 24, vibrations of the stereo device are damped by the cushion spring 26.

Furthermore, even if the user lifts up the panel 19, the retaining ring 22
Additionally, because the panel 19 cannot be lifted above a certain height, the user will not be able to touch any hazardous parts of the stereo system.

Furthermore, compared to the conventional example, there is no need to remove the turntable crane and store it in preparation for retransportation, the number of parts is small, and packaging is easy.

Further, since the clamp screw 17 can be disposed inside the turntable 20, the design is also excellent.

As described above, the present invention has the following features compared to conventional transport fixing devices:
This is extremely effective.
