Description

[Detailed description of the invention] Industrial application field The present invention is a method for quickly and easily positioning a camera, accurately and reliably fixing the camera in a desired position, and without using any tightening screws or clamping rods.
Moreover, the present invention relates to an improvement in a camera tripod head that can reliably and accurately displace the head and stably set and hold the camera displacement angle.

Prior Art Conventional camera tripods are widely used in the flat type (the tripod part is rectangular when stored) and the square type (the tripod part is triangular when stored). The rotating part of the pan head was mainly formed in a spherical shape, and the fixing means used was a tightening screw or the like to apply strong pressure directly to the rotating part to position and fix it.

In addition, in the rotating part of the tripod head, the horizontal shaft is rotatably fitted onto the vertical shaft, and the horizontal shaft can be indirectly tightened by tightening the band body with a long tightening rod. death,
The rotating part of the pan head is fixed by fixing the vertical and horizontal axes.

Furthermore, when displacing the camera after positioning the pan head in the horizontal and vertical directions of a conventional camera tripod, the side of the rotating part of the arm on which the camera is mounted must be directly tightened with a screw, etc. Tighten using
Fixation was performed after displacement.

In this displacement means, for example,
A camera head is proposed in Publication No. 31450.
In this system, one side of the camera stand is rotatably pivoted to a vertical rotation table attached to a base that fixes the tripod, and a lever with a tensioning mechanism attached to the pivot point and a pusher with a spring acting are used. A button is attached to the push button, and a click metal fitting is fixed to the push button. A camera head that can be fixed at any angle.

Problems that the invention aims to solve The rotating part of the pan head in conventional flat tripods is mainly formed into a spherical shape, and the fixing part is positioned by directly pressing the rotating part with a tightening screw etc. However, since the rotating part is spherical, there is no clear distinction between horizontal rotation and vertical rotation, so positioning the camera requires skill.
It was difficult to simply fix the camera at a desired position.

In addition, since the fixed part is simply fixed by applying strong pressure to the rotating part with a tightening screw, etc., there are drawbacks such as the camera moving during shooting due to insufficient tightening force of the screw etc. It existed.

Furthermore, even when the pan head is being stored, there is a problem in that the tightening screws and the like protrude outside the pan head main body, which obstructs the pan head's storage.

For this reason, the horizontal and vertical rotations of the pan head rotating section are distinguished, and both can be performed separately, making it possible to quickly and easily position the camera, and to position the camera at the desired position. It has been strongly desired to develop a tripod head that can be securely fixed to the tripod, and in which the tightening screws and the like do not protrude outside the tripod body and do not interfere with storing the tripod.

The biggest problem with conventional rectangular tripods is that the long clamping rod protrudes outside the camera head, so when positioning the camera, the clamping rod hits your face, etc. Not only does this pose a problem in operation, but also when the tripod is stored, the tightening rod becomes an obstacle to storage.

Therefore, there is no need to use long tightening rods.
There has been a strong desire to develop a pan head that can position a camera reliably and quickly, and in which a tightening rod is not formed outside the pan head body and does not interfere with tripod storage.

Furthermore, since the conventional camera head is simply tightened and fixed with a screw, etc., the arm often displaces due to the weight of the camera during shooting, which is not only inconvenient but also difficult to position accurately. .

Also, when displacing the camera, the horizontal position,
Most often, the angle is set at a 45-degree inclination or a vertical position, and in such cases, conventionally, each person had no choice but to arbitrarily set the required angle based on their own sense, and positioning operations required skill.

In this displacement means, the above-mentioned Utility Model Publication No. 39-31450
In the camera tripod head of the publication, when setting the camera in the horizontal and vertical positions, the fitting piece connected to the click fitting fixed to the push button with the action of a spring is attached to one leg of the camera stand. This can be done by fitting the camera into the recess, but if the camera is set at a different angle, the rod equipped with a tightening mechanism must be tightened each time.
Each person had no choice but to arbitrarily set the required angle based on their own sense, and positioning operations required skill.

At the same time, since it is simply tightened and fixed with a rod, it often shifts due to the weight of the camera during shooting, which is not only inconvenient as it is impossible to stably set and maintain the displacement angle, but also makes it difficult to accurately position the camera. was difficult.

For this reason, there has been a strong desire to develop a pan head that can accurately and reliably set the camera angle and stably maintain the set angle.

A gap 18 is vertically provided in the tapered portion 4 to divide the tapered portion 4 into two, and the gap 18 communicates with the attachment hole 11.

When fixing the pan head main body 1 in an appropriate position, the dial 9 is rotated, the pressing part 33 presses and moves the horizontal body presser 5, and the horizontal body presser 5 is guided by the tightening screw 8 and the locking recess 7. Move laterally within the pan head main body 1,
The tapered portion 4 of the fitted horizontal body 3 is tightened.

At the same time, the gap 18 provided in the tapered part 4 is closed, and since this gap 18 is in communication with the mounting hole 11, the mounting hole 11 is also tightened at the same time, and the vertical shaft 14 fitted in the mounting hole 11 is closed. is strongly tightened around its entire circumference by the mounting hole 11.

As a result, the horizontal body 3 and the vertical shaft 14 are fixed to each other, so that the pan head main body 1, that is, the camera, is prevented from rotating in the horizontal direction and is fixed at a desired position.

Further, the horizontal body 3 is tightened with a horizontal body presser 5 to integrate the two, and the horizontal body presser 5 is fitted into the locking recess 7 of the pan head main body 1 via the locking protrusion 6. Therefore, vertical rotation of the pan head main body 1, that is, the camera, is prevented and fixed at a desired position.

Next, a rotating part 35 is protruded from the lower end of the arm 22 which is rotatably pivoted to the pan head main body 1, and this rotary part 35 is connected to the pan head main body 1 through an arm screw 26. It is rotatably fitted into a fitting chamber 36 provided at the end of the.

Effects of the invention Therefore, according to the invention, the horizontal and vertical rotations of the pan head are completely separate structures, which makes positioning the camera simple and easy, and the pan head can be easily and easily positioned. The horizontal and vertical rotations can be fixed simultaneously by simply rotating the dial, so the camera can be positioned accurately and easily.

This dial fixation is achieved by tapering the horizontal body and the horizontal body presser, so just rotating the dial with a small amount of force generates a strong tightening force.
Not only is it easy to handle, but the rotation of the pan head can be firmly fixed, and there is no risk of damage to the clamping part even after long-term use.

In particular, after the horizontal body is tightened with the horizontal body presser and the two are integrated, the horizontal body presser is inserted through the locking convex portion,
Since it is fitted into the locking recess of the pan head main body, vertical rotation of the pan head main body, that is, the camera, is reliably and completely prevented, and it can be fixed at a desired position.

In addition, the horizontal fixation of the pan head main body uses tapered parts provided on the horizontal body and horizontal body presser to tighten the mounting hole, so an extremely strong tightening force is generated, and this tightening force occurs around the entire circumference of the mounting hole, tightening the vertical axis as a whole, and as a result, the horizontal body and vertical axis are fixed to each other, so the horizontal rotation of the pan head body, that is, the camera, is restricted. Movement is prevented and it can be securely and completely fixed in the desired position.

In addition, the dial of the present invention does not protrude outside the head like conventional tightening rods, but is completely incorporated as a part of the head, making it not only convenient to handle but also easy to store. It is convenient to carry because it does not get in the way at any time.

Further, the present invention is useful because it allows the camera to be positioned quickly, easily, and accurately, and it also allows the camera to be reliably fixed at a desired position.

Secondly, this invention allows you to set the tilt angle of the camera appropriately and fix it at the same time with a simple one-touch operation, which not only makes it convenient to handle, but also makes it easier to move the camera compared to conventional methods. It is something that can be done. Moreover, unlike conventional methods, there is no risk that the set position of the arm will shift due to the weight of the camera during shooting, and the desired camera angle can be set accurately and reliably, and the set angle can be stably maintained.
It can be fixed.

In addition, when displacing a camera, the angle is most often set to a horizontal position, a 45 degree tilt, and a vertical position. Since it can be fixed, there is no need to arbitrarily set the necessary angle according to each individual's sense as in the conventional case, and the positioning operation can be easily performed without requiring any skill.

Furthermore, since the displacement device of the present invention has only the push button protruding to the outside, it is not only convenient to handle, but also convenient to store, as conventional screws and the like get in the way. There is no need to worry about it, it can be easily stored, and it is convenient to carry.
