Description

The present invention is particularly suitable for a narrow room or small-scale shooting centered on the photographer.
Suitable for shooting moving up and down, left and right, etc., and a crane device for shooting, easily changing the jib length at the shooting site, using the same jib body with longer jib arm use, position This is related to crane shooting from a high position.

There are three main types of conventional crane equipment for shooting,
First, a camera is attached to the tip of the jib that swivels and moves up and down.
This is a type of jib crane that has a jib and an auxiliary jib, and when the photographic crane is moved up and down, the camera moves parallel to the ground to keep it horizontal.
Second, digitalization has progressed, and with the advent of small, high-performance digital cameras, a camera is installed at the end of a long pole-shaped jib, where it is mounted by the existing tripod head for conventional video production. There is a pole-shaped jib to install on.
The third is a heavy-duty crane device that is over 100 kg.
(For example, refer nonpatent literature 1-3).

In the currently available shooting lanes, the camera head is leveled by jib and auxiliary jib.
It is possible to keep on.

By the way, moving the equipment around the photographer, setting the small-sized photographic crane device with a large television camera, movie camera, single-lens reflex camera and other video cameras, palm-sized cameras, sports, etc. There are various types of crane photography methods.
In addition, drone appears to be large when shooting from a high position. However, drone produces wind noise in studios and the wind noise enters the recording microphone, making it difficult to use in narrow spaces, and unsuitable for long-term use due to power problems.
The type that the photographer demands when using a crane is a small jib crane, a so-called small jib crane that can be operated by one person, and a pole-shaped jib, which is also a lengthy jib photographing device that can be used easily by one person . However, with the advent of small high-performance digital cameras, this pole-shaped jib crane uses a pole instead of a large jib crane and pursues only the length during operation. The means is realized by using a video tripod for the moving part, but the usability and stationary system are not good, such as using a tripod.

However, for shooting documentaries, for example, two sets of jib crane equipment and another crane for shooting high positions are prepared, and they are used according to the shooting angle.

The pole-shaped jib crane uses a pole, etc., and the means is realized by attaching the pole to a tripod during operation and using a video tripod for the moving part. Attach the weight to the back and attach it to the video tripod head in a well-balanced place, but the video tripod has a balancer mechanism, that is, the force of trying to return the center because of the spring force. When working and shooting at high places, the ability to return to the horizontal level works so much that it is not easy to use.

Large cranes in the studio lack mobility and are heavy, so they cannot be taken out outdoors or on location.

The present invention has been made in view of the above circumstances. For example, it can be set by a small number of people centering on a photographer, and uses a scene from a low position shot with a large shoulder camera, and a carbon material or an aluminum material. For example, a low-length jib has a counterweight, but the jib length is short, so the jib movement range is about 1m above and below, and a pole-like long jib is made of 1.3m carbon material on the top. By connecting four jibs, you can shoot from a 5.2m jib without having to use a separate crane device. It is an object of the present invention to provide a shooting jib that can be mounted and can be held at any position even when a long pole-shaped jib is mounted. In addition, the weight position moves up and down, so that an unprecedented jib crane can be moved.

The present invention has been made in order to achieve the above object, and is a photographing crane device in which a jib (boom) for keeping the camera level is incorporated in a main jib or a sub-jib mechanism is built-in, or Since the gap between the main jib and the sub jib is exposed to the outside, it is provided by a mechanism capable of maintaining the level of the camera, and a long jib arm can be attached to the main jib crane.
The imaging crane apparatus according to claim 1.

According to the present invention, when the long jib is mounted, the angle of the sub jib relative to the first and second sub jib attachment arms changes, so that the camera can be moved up and down while maintaining the level. By attaching the monitor to a mechanism that keeps the camera level using the camera, it is provided that the monitor always keeps the level even when the jib is moved up and down, so that the photographer can easily take a picture. Or claims
2. The photographing crane apparatus according to 2.

According to the present invention, the jib includes two or more bracket portions on which jibs having different lengths can be attached to the base jib. A long jib can be mounted on a short jib, and arm lengths with different jib lengths are provided.
The crane apparatus for imaging | photography in any one of Claims 1-4.

According to the present invention, the jib includes two or more shaft portions for attaching the jib to the jib fulcrum attachment portion. A long jib can be mounted on top of a short jib, arm lengths with different jib lengths are provided, and a shaft or wire that keeps the camera level like a short jib is provided when a long jib is mounted .
The crane apparatus for imaging | photography in any one of Claims 1-4.

According to the present invention, the jib includes two or more shaft portions for attaching the jib to the jib fulcrum attachment portion. A plurality of long jibs can be mounted on a short jib. In this case, arm lengths with different jib lengths are provided, and there are at least one camera position with different camera positions or two or more camera positions. Provided at the same time.
The crane apparatus for imaging | photography in any one of Claims 1-6.

According to the present invention, when the balance weight is positioned behind the jib and the jib is horizontal, the balance weight can be adjusted up and down with respect to the horizontal position of the jib fulcrum. When the weight is moved to the top when the position of the jib is horizontal, the force that the jib moves back to the middle works, and even if the shooting place is separated, the force that the jib always returns to the same position works and operates safely Provided to do.
The imaging crane device according to claim 7.

According to the present invention, when the balance weight is positioned behind the jib and the jib is horizontal, the balance weight can be adjusted up and down with respect to the horizontal position of the jib fulcrum. When the weight moves to the bottom when the position of the jib is horizontal, the force that the jib goes up or down continues to work, so the tension is always applied to the jib as a human hand Therefore, since it can be operated up and down with a slight force applied to the hand, tension is kept applied, so that it is possible to perform shooting operations without causing backlash when the camera is arbitrarily stopped.
The photographic crane apparatus according to claim 8.9.

According to the present invention, a weight slide mechanism can be mounted, and the camera housing attached to the tip of the jib portion has a buoyancy when the camera is submerged from the surface of the water due to the buoyancy particularly during underwater shooting. Neutral buoyancy can be obtained with respect to buoyancy by a slide-type weight mechanism for adjustment. The photographing crane apparatus according to claim 11, which also has a function of finely adjusting a balance of the weight.

According to the present invention, particularly when taking a picture underwater, the camera housing attached to the tip of the jib is less likely to sink into the water by adjusting the buoyancy when the camera dives from the water surface under the buoyancy. It is possible to sink into the water by pulling the jib at a place away from the fulcrum by the auxiliary pulling part.
A crane apparatus for photographing according to claim 12 is provided.

According to the present invention, when assembling a long arm jib with an arbitrary length, the long arm jib has an electrical contact at the joint, and the power supply to the camera, the control signal, the tally signal, and the video signal contact from the camera are connected. It has a signal connector to the outside in the long arm jib of the first stage and the tip, which can pass all or one or more signals.
A crane apparatus for photographing according to claim 13 is provided.

As described above, the present inventor has noticed that various shooting scenes are shot with different jib cranes when using the jib. In addition, the jib camera mounting part and the weight part exist only in a straight line in the conventional position of the jib, and the jib camera mounting part and the weight part shift the jib in the middle when the weight is shifted from the conventional straight line to the upper part. I noticed the law that the camera position of the jib and the weight of the jib's camera mounting part and the weight part moved from the straight line to the lower part, and the jib only moved up or down.

With this crane, shooting settings can be realized by one person, and a long jib can be easily attached, resulting in a longer jib length and a larger vertical shooting range. If you set it with a short jib, the swing width will be small, but by installing a heavy camera, you can complete almost all jib shooting scenes from low position to high position shooting with this one .

As is apparent from the above description, according to the present invention, a long jib can be attached to the main jib body, a single heavy camera can be used at a low position, and a light camera can be used with a long jib. This makes it possible to shoot cranes that are suitable for shooting purposes. In particular, since a pole-shaped crane that is generally used is mounted on a tripod and used, the tripod has a strong force to return to the horizontal position with the force of a spring, so this is a heavy camera with a weight of around 8 kg to 15 kg. When the camera is tilted, the counter balance mechanism works, and the function that stops at any angle stops, so the pole-shaped jib is balanced with a weight on the back. Because of the spring force that tries to return to the horizontal position, it is very difficult to shoot a high position due to the nature of the tripod for professional video cameras. Even when a monitor is installed and operated, it can be kept level, making it easy for the photographer to see. Also, this system is easy to use because it is stationary in a movable range from top to bottom, even in a short jib at any position or in a jib with a reduced length. In addition, when shooting the balance of the jib, the jib can be leveled and the weight position can be adjusted up and down, so if you adjust the weight position while keeping the jib horizontal when adjusting the jib balance, it will be in the middle of the jib. Since the arm always returns to the same position by utilizing the returning property, safety can be secured because the habit of returning to the center when the hand is released from the jib can be used without locking the jib. If the weight position is adjusted while keeping the jib horizontal while adjusting the jib balance, the arm will always move fully up or down by using the property of moving up or down the jib. The moving range, that is, the magnification slightly lower than the support axis, can be weakened up or down, so the photographer can always shoot with tension, and it can be operated with hands with little backlash and is very smooth You can shoot a simple shooting screen. Also, by raising and lowering the weight position, the buoyancy can be adjusted in underwater shooting, and the photographer's fatigue during shooting can be alleviated. If the housing is slightly larger, the buoyancy is large.In that case, the mechanism that pulls the pole down can be used to pull the mechanism down by hand, or you can put it in the water instantly so that you can put your foot on the pulling mechanism. It becomes possible. Even if a weight slide mechanism is used, the same effect is obtained and it is easy to use.

In one embodiment of the present invention, a long arm jib is used in more detail.

Embodiments of the present invention will be described below with reference to the accompanying drawings. AA jib shown in FIG.
106 jib fulcrum mounting part is constructed from 107 tripods, and C shaft 2 part fulcrum and 112 auxiliary jib mounting arm 2 are permanently fixed (that is, tripod 106 jib fulcrum mounting part mounting movable part A is attached). Shaft is constantly fixed) Jib up and down (camera up
Since the 101 auxiliary jib arm (sub-jib) moves in parallel with the AA jib when the AA jib is moved up and down, the level is always maintained even if the AA jib moves up and down. Attach the 103 video head to the 102 head, and attach the BB video camera.
When attaching the long arm jib, the first stage of the long arm jib is attached to the AA jib from the 110 long arm jib attachment bracket 2 and the 109 long arm jib attachment bracket 1. Depending on the shooting site, the 4th and sometimes the 5th stage of the Nung Arm Jib are installed. Attach a 108 video camera to the end of the long arm jib. CC video camera 2 and B video camera can be used simultaneously. Adjust the balance of the weight side and the camera side by adjusting the length of the 104 weight balance adjustment shaft with the position of the 105 balance weight with the AA jib horizontal.

FIG. 2 shows the entire photographing crane apparatus, and is a view when used with a short jib. Adjust the weight of 104 weights according to the weight of the BB video camera.
When the jib arm is short, there is an advantage that a heavy camera can be mounted.

FIG. 3 is a diagram when 113 monitor is installed in FIG. The long arm jib is connected from the 1st stage to the 4th stage. In the long arm jib, the length of the long arm jib can be increased or decreased except for the first stage and the tip.

FIG. 4 shows the embodiment shown in FIG. 1 with a 114 shiv fulcrum mounting extension fitting, a 115 horizontal mechanism holding bracket attached to the tip of the long jib arm, and a 115T horizontal mounting holding bracket and 114 jib fulcrum mounting extension 117 assisting Fix the jib arm 2. The joint part of the 115 horizontal mechanism holding bracket and the 117 auxiliary jib arm operates. The joint part of 117 auxiliary jib arm 2 and 114 fulcrum attaching part extension metal fittings also operates. This maintains the level of the 108 video camera even when tilted.

5, FIG. 6, and FIG. 7 are diagrams of examples of weight position mounting. FIG. 5 shows a standard mounting method. When the jib is made horizontal with respect to the fulcrum, the center of the weight and the center of the fulcrum become parallel. In parallel, when the jib arm is tilted, if the weight side and the camera side are balanced, the arm rests cleanly at any angle.
In the case of FIG. 6, when the jib is leveled with respect to the fulcrum, the weight center and the center of the fulcrum are on the weight. If the weight is set above the center of the weight and the fulcrum when the jib is leveled, a habit of returning to the horizontal when the hand is released is born. As a result, even when the hand is released, it always returns to the same position, so that it is very convenient because there are many shootings such as swimming as shown in FIG.
In FIG. 7, the center of the weight and the center of the fulcrum are downward when the jib is horizontal with respect to the fulcrum.
If you move down in parallel, if you move a little above the neutral point, you will have a habit of going up, and if you move it down a little, you will get a habit of going down. The weight may be slid up and down, or a metal fitting that draws an arc from a fulcrum.

FIG. 8 is a diagram with 116 monitor mounting brackets attached, and the monitor angle is always constant because it moves in parallel with the jib body. In the case of the usage as shown in FIG. 9, when the jib arm is lifted up, and the monitor is fixed to the boom, it is very difficult to see when the boom angle is raised. Since the underwater housing has buoyancy, particularly in the case of underwater photography, the 118 auxiliary pull portion is difficult to dive in the air and underwater. In order to solve this problem, the 121 slide shaft is positioned on the 121 slide weight fixing bracket attached to the jib body, and the 119 slide shaft slides on the slide shaft. Not only underwater, but also useful for fine adjustment after balancing with the slide mechanism. The position of the balance weight may be realized across the fulcrum on the front side or the rear side of the jib body. Moreover, you may use for the adjustment of FIG. 6, FIG. 7 by attaching to a vertical part.
