Abstract

PURPOSE:To automatically restore a breasting section to a fixed position, by controlling the position, to which the breasting section of the camera returned and, on the other hand, providing a spring which elastically holds the state of the breasting section when the breasting section is forcedly moved to the lower section of the camera. CONSTITUTION:A breasting unit 2 is constituted by uniting a breasting arm 24, gear keeping plate 13, angle controlling ring 16, and gear guide 9 in one body and projecting the shaft 10 of a locking knob 3 from the gear guide 9. In case when the breasting unit 2 is at the position A by means of a built-in coil spring 26, a breasting section 25 tends to move to the position of the horizontal direction against a camera 1 due to the coil spring 26, but the movement of the breasting section 26 in the direction from the position A to another position B is controlled by the elasticity of a spring 27. Moreover, it is necessary to move the breasting unit 2 towards the position A with a force which is stronger than the holding force of the spring 27 for arm when the breasting unit 2 is moved from the position B to another position C. Therefore, the breasting unit automatically returns to a prescribed position even when the camera is removed from the shoulder and the breasting unit or camera is never damaged.

Description

[Detailed Description of the Invention] The field of application of the Emperor and the above is related to the shoulder type Coco Camera 1;

BACKGROUND OF THE INVENTION Conventionally, Njorder type cameras, especially those used for entertainment or broadcasting, have often been provided with a breastplate to maintain the stability of the camera during JhjpF.

By the way, this type of breastplate is rotatably attached to the bottom of the camera, and is oriented perpendicular to the camera when the camera is in use and when not in use.

It is constructed so that it can be rotated and assisted in the horizontal direction.

Problems to be Solved by the Invention However, in the case of such a breastplate, the rotation of the breastplate is controlled by a locking knob, but if the breastplate is in use, that is, when it is perpendicular to the camera. Another problem is that when the camera is taken off the shoulder and placed on a desk or the like, the weight of the camera may damage the breastplate mechanism and cause it to come loose.

The present invention eliminates these conventional drawbacks,
When you remove the camera from your shoulder, the 1st position will reach a certain position.
The purpose is to provide a breastplate device that will return to normal condition.

Means for Solving the Problems In order to achieve the above object, the present invention provides means for automatically returning the breastplate to a certain position when the camera is removed from the shoulder, and also This device is provided with a means for locking it in that state when it is moved.

Therefore, according to the present invention, the breastplate can be easily protected, and the camera can be handled very easily.

The configuration of the example is shown. In the figure, 4 is a lock plate fixed to the 111 side of the camera 1 with a screw 5, and a screw hole 6 in the center of which @10 of the lock knob 3 is hinged;
Each has a gear portion 7 and a lock hole 8 on its outer periphery. A gear guide 9 has a hole 11 through which the shaft 10 of the lock knob 3 passes, and one of the gear guides is provided with a protrusion 12 corresponding to the lock hole 8 of the lock plate 4. Furthermore, a fixing protrusion 15 for fixing the gear press plate 13 with a screw 14 is provided on the other surface. Reference numeral 16 denotes a one-piece stopper 1 which has a gear part 17 corresponding to the gear part 7 of the lock plate 4 on one side, and has a hole 18 in the center for allowing the vehicle 10 to pass through.
htJl, 'tall ring, which has a long hole 22 that exposes the protrusion 15 of the gear guide 9, an adjustment piece 19, and a stopper 23. Reference numeral 24 designates a one-flange arm having an IIN abutment arm 25, which also has a protrusion 27 that serves as a stopper for the protrusion 19 of the gear guide 9 and the stopper 23 of the angle regulating ring 16, and holds one end of the coil spring 26. 28
is provided in a part of the gear holding plate 13, and the coil spring 26
This is an arm spring that is fixed to the breastplate arm 24 by a notch part holding one end of the 27 screw 28.

In the above-mentioned real sister example, we will explain the order of 6-marked cows.

As shown in FIG. 5, the protrusion 19 of the gear guide 9 is caused to protrude from the elongated hole 22 of the control ring 16. In this state, the ring 16 can rotate within the range defined by the elongated hole 22 using the protrusion 15 as a fulcrum. Figure 6.

FIG. 7 shows a state in which the breast plate arm 24 and the coil spring 26 are matched to each other in the state shown in FIG. 5. Next, when fixing the gear press plate 13, one end of the spring 26 is hooked to the notch 28, rotated 120 degrees, and fixed 181 to the protrusion 19 of the gear guide 9 with the screw 14. As a result, the sandals, breast plate arm 24, gear press plate 13, angle regulating ring 16, and gear guide 9 are integrated. Here, by making the shaft 10 of the lock knob 3 protrude from the gear guide 9, a one-punch unit is constructed.

Next, the protrusion 12 of the gear guide 9 is made to correspond to the lock hole 8 of the lock plate 4 fixed in advance to the camera l, and the lock knob 3 is made to correspond to the screw hole 6; It is fixed as shown in FIG. In this case, the built-in coil spring 26 positions the breastplate 2 in the position shown in FIG. That is, in this case, the coil spring 26 attempts to move the chest plate 25 to a position horizontal to the camera l, but the elasticity of the spring 27 restricts the movement from the position A to the direction B. , Therefore, in the case of a whirlpool rod in which the 1st stopper 2 is placed in the horizontal position B, the spring 27 for the arm is
It will be moved against the elasticity of. Also, breastplate 2
When moving the chest plate 2 from position B to position C, it is necessary to move the chest plate 2 in the direction A with a force greater than the holding force of the arm spring 27.

411tb of the breastplate 2 from B to C or D direction is until the protrusion 19 of the gear guide q hits the protrusion 27. In addition, when setting the position C or D of +-pad 2, that is, the position of the breastplate at 01 from A or D from A, (adjusting the distance between C and D), loosen lock knob 3 and set gear 1. When connecting parts 7 and 17, the angle regulating ring 16 may be rotated and set as shown in FIG. 5 in this state.

Effects of the Invention As explained above in the embodiments, according to the present invention, it is of course important to regulate the position of the breastplate when the camera is in use.
Even when the camera is taken off the shoulder, the camera can be automatically set to a predetermined position 11,111 m, so the camera has the advantage of being easy to handle.

In particular, this position is a position where the breastplate can easily move to a horizontal position when looking at 1F when the camera is placed on the desk.
Even when it is placed on the shoulder again, it can be immediately moved to a vertical position or a position close to it, which has the advantage that the operation becomes extremely easy. According to the present invention, the breastplate is moved to a horizontal position simply by applying the weight of the camera to the bodyguard, so that the breastplate or the camera will not be damaged.
