Description

[Detailed Description of the Invention] The present invention relates to an insulator placed on the leg of a main body of a device such as a record player.

Traditionally, legs made of vibration-absorbing material or legs with an insulator mechanism have been attached to the legs of devices such as record players, but conventional insulators only have a vibration-absorbing effect. The vibration of the main body of the device due to the reaction of the rotational vibration of the turntable, etc., will increase the adverse effects such as cross-modulation distortion occurring in the reproduced signal.

The purpose of this invention is to solve the above-mentioned drawbacks of the conventional insulator, and to not only allow the height to be adjusted arbitrarily, but also to fix the spring action as necessary.
Moreover, it is an object of the present invention to provide an insulator with a locking mechanism that can be easily attached to the main body of the device.

The structure of the present invention will be described with reference to the drawings together with its embodiments. In the drawing, reference numeral 1 denotes a main body of a device such as a player, and leg mounting holes 2 are provided in the lower surface.
3 is a spiral leg shaft that is screwed into the leg mounting hole 2 to adjust the height; 4 is a guide shaft that is slidably inserted into the leg shaft 3 and supported so that it does not come out. , 5 is a covered cylindrical upper adjustment body which is screwed into the leg shaft 3, and 6 is a tray-shaped lower adjustment body which is screwed into a threaded portion formed at the lower end of the guide shaft 4. Then, the peripheral wall 6c fits loosely into the peripheral wall 5c of the upper adjustment body 5, and the upper adjustment body 5
By descending, the inner bottom surface of the upper adjustment body 5 comes into contact with the upper end 7 of the peripheral wall. Reference numeral 8 denotes a spring means arranged between the leg shaft 3 and the guide shaft 4.

To explain the above configuration in detail, the upper adjustment body 5
is supported by screwing the leg shaft 3 into the screw hole 5a at its center, and is raised and lowered by rotating the upper adjustment body 5. Reference numeral 3a denotes a flange formed at the lower end of the leg shaft 3, which serves as a stopper for the upper adjustment body 5 and also serves as a spring seat for a coil spring serving as the spring means 8. The upper adjustment body 5 has an inverted tray shape with a peripheral wall 5c, and a non-slip portion 5b is formed on the outer periphery of the peripheral wall 5c. The lower adjustment body 6 has a tray shape symmetrically with the upper adjustment body 5, and has a smaller diameter than the upper adjustment body 5, and has a central screw hole 6a connected to the lower end of the guide shaft 4. The formed threaded portion is screwed in, and the peripheral wall 6c is loosely fitted into the peripheral wall of the upper adjustment body 5. 6b is a non-slip portion formed on the outer periphery. A spring seat 3b corresponding to the flange 3a is provided at the lower part of the guide shaft 4. Reference numeral 9 denotes a cushion material provided to cover the spring means 8.

Therefore, by rotating and lowering the upper adjustment body 5 against the elastic force of the spring means 8, the inner bottom surface can come into contact with the upper end 7 of the peripheral wall, thereby locking the spring action. By rotating the entire adjustment body 6, the screwing of the leg shaft 3 into the leg mounting hole 2 can be adjusted, and the height of the leg can be adjusted.

In the above configuration, the guide shaft 4 is included in the leg shaft 3.
is inserted and makes a piston movement, it can slide freely in the vertical axis direction (axial direction), but because the guide shaft 4 is restricted within the leg shaft 3, it can move in the horizontal direction. For example, in the case of a record player, it is possible to effectively prevent the entire device from shaking due to the reaction of rotational vibration of the turntable without impairing the effect of the insulator.

Furthermore, when using the device in a quiet environment, by bringing the upper adjustment body 5 and the lower adjustment body 6 into contact with each other, the spring action by the elastic means can be locked and the device can be operated. For example, it is possible to eliminate cross-modulation distortion that occurs when playing a record player while the spring action is being applied by the elastic means.

According to the insulator with a locking mechanism of the present invention, it is possible to effectively prevent the entire device from shaking horizontally without impairing the effectiveness of the insulator. Since the spring action can be locked by bringing the vertical adjustment body into contact with the spring against the spring force of the spring, the spring action is activated by the spring when the device is used in a quiet environment. It is possible to eliminate cross-modulation distortion, etc. that occurs when playing a record player in a state where the

Furthermore, it is possible to adjust the height as desired by rotating the entire upper adjustment body and lower adjustment body, for example,
When packing and transporting, the entire leg can be removed by pulling out the leg shaft from the leg mounting hole.
