Description

TECHNICAL FIELD The present invention relates to a tripod adapter for fixing a portable TV camera to a tripod.

(Prior art and its problems) With the conventional one-touch type tripod adapter, the edge fittings provided on the front and rear bottoms of the camera are faced to each other so as to be fixed. A tension bar is attached to one of the edge fittings in order to absorb dimensional errors in manufacturing the tripod adapter. However, the holding force of the tension bar is limited, and when an external force exceeding the holding force acts on the camera, the camera may rattle slightly.

(Purpose) In order to eliminate the drawbacks, the present invention is designed so that the camera can be fixed with one touch without rattling.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

As shown in FIG. 2, the edge fitting 1 is provided on the front bottom surface of the camera.
, And a V-edge metal fitting 2 is provided on the rear bottom surface.

As shown in FIG. 1, there is a rotary lever 4 near the center of the base 3 of the tripod adapter, and a cam groove 5 and a pin 6 are provided on the rotary lever 4 to enable the operation of moving and fixing the bottom of the camera. It constitutes the operation rotary lever. A moving plate 7 is connected to the cam groove 5 by a pin 8, and a camera bar 10 and the moving plate 7 are connected by a torsion bar 9.
Is connected. The camera pedestal 10 is provided with a positioning pin 11 for mounting the camera-side V-edge metal fitting 2 indicated by a chain double-dashed line in FIG. 1, and these members are used to mount the V-edge metal fitting 2 on the camera pedestal 10. A moving member that moves 2 in the front-rear direction with respect to the base 3 is configured. The V-edge metal fitting 2 meshes with the base 3 as shown by B in FIG.
The hooking tool 12 shown in FIG. 4, which is a sectional view taken along line B, is provided. On the other hand, regarding the fixing of the V-edge metal fitting 2, a connecting rod 13 is rotatably attached to a pin 6 provided on the rotary lever 4, and a pin 14 is provided at the other end of the connecting rod 13 so that a lock having a symmetrical shape is formed. The lever 15 is connected to the pin 14 by stacking two levers. The lock lever 15 is rotatable around a fulcrum shaft 16 as a fulcrum, and is rotated by a spring 17 in a direction of pushing the V edge fitting 2 attached to the camera side (shown by a chain double-dashed line in FIG. 5). These members form a lock member for fixing the V edge fitting 2.

Next, in order to fix the front of the camera, the hook 19 having the inclined surface 18 that meshes with the edge fitting 1 on the bottom surface of the front of the camera shown in FIGS. 22 is attached to the base 3 so that a force always acts in the direction in which the edge fitting 1 is pressed, and these members constitute a lock member for fixing the edge fitting 1.

A safety lock release button 23 is provided at the tip of the rotary lever 4 so as to engage with a safety lock 24 embedded in the base 3.

 This operation will be described below.

When attaching the camera to the tripod adapter, set the rotary lever 4 to the position I (Fig. 1), and attach the V-edge metal fitting 2 attached to the rear bottom of the camera to the camera pedestal.
Place it between pins 11 provided on 10. In this case, the edge fitting 1 on the front bottom surface of the camera is in the position shown by the chain double-dashed line in FIG. Next, rotate the rotary lever 4 to the position II position (5th
When operated up to (Fig.), The moving plate 7 slides by the pin 8 engaged with the cam groove 5, the V-edge metal fitting 2 on the camera pedestal 10 moves to the position of the chain double-dashed line, and the hooking tool Mesh with 12.

Along with the movement of the V edge fitting 2, the edge fitting 1 attached to the front bottom surface of the camera also moves as a unit, and the hook 19
When the inclined surface 18 and the edge fitting 1 are in contact with each other, the spring pressure of the spring 22 acts and the edge fitting 1 is always sandwiched and fixed by the base 3 and the hook 19 (FIG. 5). When the rotary lever 4 is continuously operated to the position III, the connecting rod 13 moves following the movement of the pin 6 as shown by the chain double-dashed line in FIG. The lock lever 15 pushes the V-edge metal fitting 2 by the action of the spring 17 which tries to rotate as a fulcrum, and the hook 12 provided on the base 3 causes the V-shaped metal fitting 2 to move to the V-shape.
It is a mechanism for sandwiching and fixing the edge fitting 2. When the rotary lever 4 is operated from the position I to the position II, the lock lever 15 does not rotate in the direction in which the V edge fitting 2 is sandwiched.

(Effects) The tripod adapter according to the present invention secures the camera by one-touch operation of the rotary lever 4 by combining the edge fitting 1 provided on the camera, the hook 19 provided on the adapter base 3, the V edge fitting 2 and the lock lever 15. It can be fixed to.
