DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographing means for photographing an object from the air according to various uses such as city planning, road design, forestry survey, disaster survey, archaeological survey, sports broadcasting, air flow and the like. The present invention relates to a device for holding various devices such as a measuring device for measuring in the air, various sensors for investigating habits of birds in the air, a transmitter and a receiver for use in radio wave relay in the air.

2. Description of the Related Art In recent years, in order to photograph various objects from the air, a device in which a frame holding a camera is suspended from a balloon which is anchored by an anchoring rope is used.
The balloon is of a spherical or airship type.

[0003]

However, when the balloon is formed into a spherical shape, it has the advantage of being small and capable of obtaining large buoyancy. However, the balloon is easily swung by the wind, and the balloon is moored on the ground by mooring lines. Because the camera swings with the swing of the balloon, the inertia energy is large,
It takes a long time to stop, and accurate shooting cannot be performed efficiently. On the other hand, if the balloon is configured as an airship,
The swinging can be reduced by improving the opposition to the direction of the wind, but in this case, the buoyancy is dispersed, so that the buoyancy is inferior to that of a spherical shape, the size must be increased, and the cost increases. In addition, even if the balloon is formed in any shape, after all, it is not possible to prevent swinging due to the wind, so in the case of applications that allow intermittent work such as shooting, It is possible to work by selecting weather conditions with weak winds, but it is necessary to make the equipment function regardless of bad weather conditions such as sports broadcasting, measurement of airflow, survey of bird habits, radio wave relay etc. It cannot be used for certain applications, and cannot be used for general purposes.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and uses a small-sized spherical balloon having a large buoyancy to control various devices in the air without being affected by weather conditions. It can be held in a stable state that is almost stationary at a position, so that it can be applied not only to a device that functions intermittently but also to a device that functions continuously for a long period of time to obtain versatility. It is another object of the present invention to provide an aerial holding device for a device that can reduce the cost.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, an aerial holding device for a device according to the present invention comprises a balloon formed in a spherical shape, and a plurality of hanging lines for hanging the device around the balloon. And a holding net placed over the balloon, and a plurality of tension cords holding the holding net pulled downward from three or more places.

An aerial holding device of another apparatus according to the present invention for achieving the above-mentioned object is provided with a linking means for holding the balloon so as not to be detached from the holding net in the above configuration. is there.

[0007] In each of the above configurations, the device can be hung from the periphery of the balloon by a plurality of hanging cables, and the devices are arranged so that the horizontal axis intersects the upper and lower two points. It can be connected to the suspension line by suspension means having a bendable joint.

According to the present invention configured as described above,
By holding the holding net over the balloon in a state where it is pulled downward with three or more pulling ropes at multiple locations, various devices can be affected by weather conditions while using a small balloon with large buoyancy. Therefore, it is possible to maintain a substantially stationary state in a substantially fixed position in the air without any trouble.

Then, the balloon 1 is filled with helium gas, and the balloon 1 is raised to a desired altitude in a state where the imaging device 4 is suspended by the suspension ropes 3 while pulling out the tension cords 6 and the multi-core cord 50.
When photographing at a fixed position, the pull cord 6 is releasably connected to the fixed portion, and the balloon 1 and the like are anchored by the pull cord 6. Then, by holding the holding net 5 over the balloon 1 and holding the four corners in a state where the four corners are pulled by the pull cords 6, the balloon 1 that is about to float by buoyancy moves the center of the holding net 5 upward. Press. In addition, the balloon 1 is linked to the holding net 5 and the like by the strings 8, 9 and the like as described above, and is held at a position so as not to be separated. As a result, the balloon 1 is fixed to the holding net 5, and
Since the holding net 5 is formed at the corners and is not easily deformed, it is possible to hold the balloon 1 in a substantially fixed state so as not to swing by the wind after all.

When the order is completed in this way, the target subject captured by the monitor television camera 29 is received by the monitor television receiver of the control device on the ground to confirm the subject. If the angle of the camera 28 on the vertical plane is shifted, the motor 45 is rotated forward or backward, and the camera 28, the monitor television camera 29, etc. are rotated forward or backward in the vertical direction as described above. If the angle of the camera 28 is shifted in the plane, the motor 39 is rotated forward or backward, and the support frame 25, the camera 28, the monitor television camera 29 and the like are moved in the vertical direction as described above. By rotating forward or backward around the axis 23, the angle of the camera 28 is correctly matched with the subject. Thereafter, the shutter switch of the camera 28 is operated under the control of the control device, and the subject can be photographed.

At the time of photographing, even if the wind is blowing a little, the balloon 1 hardly shakes as described above.
Since the camera 28 and the like are also suspended from the plurality of locations around the balloon 1 by the suspension cable 2, there is almost no possibility of shaking. A bendable joint 20, in which the camera 28 and the like are arranged so that the horizontal axes 18 and 19 intersect at two upper and lower positions even if the balloon 1 or the camera 28 and the like is slightly shaken by strong wind or the like,
Since it is suspended by the suspension joint 14 having the suspension 21, the posture is restored by its own weight, and the vehicle can be directed to the correct angle. In this state, the subject can be photographed at a correct angle by remotely controlling the photographing device by the control device on the ground. Therefore, the subject can be correctly recognized after shooting.

It is to be noted that airflow and the like can be measured by using a measuring instrument in place of the camera 28 and the monitor television camera 29, and the habits and the like of birds can be investigated by using various sensors. It can be used for radio wave relay by using a device and a receiver, and can be applied to various other devices.

[0022]

As described above, according to the present invention, the holding net covered by the balloon is held in a state where it is pulled downward by three or more pulling ropes at three or more places, thereby providing a small and large buoyancy. The various devices can be maintained in a substantially stationary position at a substantially fixed position in the air, without being affected by weather conditions, while using the spherical balloon. Therefore, the present invention can be applied not only to a device that functions intermittently but also to a device that functions continuously, so that versatility can be obtained and the cost can be reduced.

Further, by holding the balloon so as not to be detached from the holding net by the linking means, the balloon is detached from the holding net due to a positional shift with respect to the holding net even if the device is swung by a relatively strong wind. Can be prevented, the balloon, the device, and the like can be reliably held in the air, and the reliability can be improved.

Further, by suspending the device from the periphery of the balloon with a plurality of suspension cables, it is possible to suppress the swing of the device and maintain the device in a stable state.

Also, by connecting the equipment to the suspension cable by means of suspension means having bendable joints arranged so that the horizontal axis intersects the upper and lower two points, many balloons are shaken by strong wind or the like. The device can be immediately returned to its original position by its own weight.
