However, assembling the scaffold to perform high-altitude photography requires a great deal of labor. In addition, the shooting crane device often used in a studio or the like requires a large space, cannot be used in a small shooting location, is dangerous when there are people around it, and is very expensive. is there.

Disclosure of the invention

[0003] The present invention solves the above-described problem in the case of performing shooting from a high place, and is a light-weight that can be easily operated and can perform shooting at a high place safely even in a narrow place. To provide an inexpensive camera pedestal.

The camera pedestal of the present invention has a carrier that can move horizontally, a pole support that is supported on the carrier so as to be able to turn horizontally, and an upright standing on the pole support with the center of rotation of the pole support as the axis. A telescopic pole consisting of a lower pole, a middle pole, and an upper pole, telescopic means for expanding and contracting the telescopic pole, and a camera fixing part supported on the upper part of the upper pole so as to be swingable with a support shaft perpendicular to the axis. , To the lower pole

And a tilt pulley provided at the top of the lower pole and a tilt pulley provided at the lower part of the middle pole, and one end is tilted. The above-mentioned problem is solved by providing the front and rear tilt wire ropes respectively connected to the front and rear of the support shaft of the S camera fixing portion, which are connected to the operation means and the other end force. are doing.

The camera pedestal of the present invention raises and lowers the camera by extending and retracting the telescopic pole in the vertical direction, so that it is possible to safely shoot a high position force even in a narrow place. In addition, even if the camera is raised to a place where humans cannot reach, the tilt operation can be performed by the tilt operation means provided on the lower pole. Since the pole support can be swiveled horizontally on the carrier, panning around the axis of the telescoping pole is possible, making it easier to move the carrier horizontally.

[0005] The camera pedestal has a simple structure, is lightweight and inexpensive, and can be easily operated.

A hydraulic cylinder, a ball screw, or other means can be appropriately selected as a means for expanding and contracting the telescopic pole. Also, the middle pole and the upper pole should be extended and contracted at the same time, and even U should be extended and contracted.

[0006] The expansion / contraction means includes a constant load spring provided at the base of the lower pole for canceling the load on the middle pole, the upper pole, and the camera, and a pulley for raising and lowering provided on the upper part of the lower pole. It is wrapped around a wire rope for lifting and lowering the middle pole, one end of which is connected to the constant load spring, and the other end is connected to the lower part of the middle pole, and a pulley for raising and lowering provided at the upper part of the middle pole, and one end is If the upper pole is connected to the base of the lower pole and the other end is connected to the lower part of the upper pole, the load of the middle pole, the upper pole, and the camera will be offset by the constant load spring. It does not require large force for expansion and contraction, and can be easily moved up and down manually.

[0007] When a handle for lifting and lowering and turning is attached to the middle pole, the operation of lifting and lowering and turning is easier.

If a camera monitor is provided on the lower pole, it is possible to take pictures even when the camera is moved to a higher place and easily check the video.

Further, one ends of the front and rear tilt wire ropes are respectively connected to the tilt operation pulleys provided in the tilt operation means, and a camera tilt pulley having the same diameter as the tilt operation pulley is rotatable around the support shaft. And the other end of the tilt wire rope is connected to the upper part of the camera tilt pulley while the camera is horizontal. Since the pulley and the camera tilt pulley have the same diameter, the rotation angle of the tilt operation pulley and the camera tilt angle are equal, and the load applied to the tilt wire rope is constant regardless of the camera tilt angle. Operability is improved.

[0008] Furthermore, the camera fixing portion has a structure in which the camera can be fixed at a position where the center of gravity is on the axis of the support shaft, so that the operating force of the tilt operating means is kept constant even when the tilt angle of the camera changes. Therefore, there is no need to provide a counterweight, a balance mechanism, and the like, and light weight can be achieved. When the carrier is provided with a caster on the moving device, the carrier can move to an arbitrary position on a plane.

[0009] When the carrier is provided with the track running wheels in the moving device, it is possible to accurately move along a predetermined path along the track.

BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 1 is a perspective view of a camera pedestal showing an embodiment of the present invention, FIG. 2 is a side view of the camera pedestal, FIG. 3 is a cross-sectional view taken along line AA of FIG. 2, and FIG. FIG. 5 is a perspective view of the pedestal in a contracted state, and FIG. 5 is an explanatory view of a method of winding a wire rope of the pedestal for a camera.

In the camera pedestal, a pole support 15 is supported on a carrier 22 that can move horizontally by a moving device 43 including a caster 17 and a level adjustment mechanism 16 so that the pole support 15 can be horizontally turned by a turning mechanism 23. A telescopic pole 30 is erected on the support 15 with the center of rotation as the axis Y. Here, moving device mounting brackets 42 are fixedly mounted on the carrier 22 on all sides, and the moving device 43 is mounted on the moving device mounting bracket 42. If the moving device 43 can be moved in a stable state, the number and position of the moving device 43 may be changed as appropriate. No problem.

[0012] The telescopic pole 30 is composed of a lower pole 1, a middle pole 2, and an upper pole 3 which are slidably fitted to each other. The force camera fixing part 9 is swingably supported by the shaft 31. A camera 18 is mounted and fixed on the camera fixing section 9.

A pulley 11 for tilt operation is rotatably attached to the lower pole 1 with a tilt operation shaft 19 perpendicular to the axis Y. The tilt operation shaft 19 extends to the right in FIG. 3 (to the left as viewed from the photographer located behind), and at the tip thereof, the tilt operation shaft 19 and the tilt pulley 11 are rotated. A tilt handle 21 for performing a tilt operation is attached. [0013] A camera monitor 24 is provided near the tilt operation axis 19 of the lower pole 1.

The middle pole 2 is provided with a lifting handle 20 for changing the height of the camera 18 and the direction of the camera 18 by moving the middle pole 2 up and down and turning.

A constant load spring 5 is provided on the pole support 15 at the base of the lower pole 1. The constant load spring 5 is for canceling the loads of the middle pole 2, the upper pole 3, and the camera 18, and for example, a commercially available Conston (registered trademark) spring or the like is used.

As shown in FIG. 5, a lifting pulley 6 is provided above the lower pole 1, and a wire rope 7 for lifting the middle pole is wrapped around the pulley 6 for lifting, and one end is fixed. The other end is connected to the lower part of the middle pole 2.

An elevating pulley 10 is provided on the upper part of the middle pole 2, and an upper pole elevating wire rope 8 is wrapped around the elevating pulley 10, and one end of the wire rope 8 is attached to a pole support 15 at the base of the lower pole 1. The other end is connected to the lower part of the upper pole 1!

[0015] Further, a tilt pulley 12 is provided before and after the upper portion of the lower pole 1, and a tilt pulley 13 is provided before and after the lower portion of the middle pole 2, and the tilt pulleys 12 and 13 are respectively provided before and after. The tilting wire rope 14 is wound around, one end is connected to the tilting pulley 11, and the other end is connected before and after the support shaft 31 of the camera fixing unit 9.

When taking a picture using this camera pedestal, the photographer first adjusts the level of the carrier 22 with the level adjustment mechanism 16, the pole support 15 turns horizontally, and the telescopic pole 30 moves in the vertical direction. Make it stretchable.

When changing the height of the camera 18, the lifting handle 20 is manually raised and lowered. A middle pole lifting wire rope 7 is wrapped around a lifting pulley 6 above the lower pole 1, one end of which is connected to the constant load spring 5 and the other end is connected to the lower part of the middle pole 2. The wire rope 8 for raising and lowering the upper pole is wrapped around the pulley 10 for raising and lowering the upper part of the middle pole 2, and one end is connected to the pole support 15 at the base of the lower pole 1, and the other end is formed at the lower part of the upper pole 1. , The camera 18 moves up and down a distance twice as long as the moving distance of the elevating handle 20.

[0017] Gravity acting on the camera 18, the camera fixing section 9, and the upper pole 3 is moved by the upper pole lifting wire. It is hung on a rope 8, and its tension is supported by a lifting pulley 10. The tension of the upper pole elevating wire rope 8 supported by the elevating pulley 10 and the gravity acting on the middle pole 2 including the elevating handle 20 are applied to the middle pole elevating wire rope 7. A constant tension is always applied to the middle pole lifting wire rope 7 by the constant load spring 5 so as to cancel each other, so that no large force is required to extend and retract the extension pole 30.

[0018] Since the camera monitor 24 is provided on the lower pole 1, the video taken even when the camera 18 is moved to a high place can be easily confirmed.

When changing the direction of the camera 18, the lift handle 20 is manually turned. Since the telescopic pole 30 turns together with the pole support 15 by the turning mechanism 23, the camera 18 turns horizontally by the turning angle of the lifting handle 20.

When changing the tilt angle of the camera 18, the tilt handle 21 is manually operated, and the tilt operation pulley 11 is rotated by the tilt operation shaft 19.

Since the tilt wire rope 14 is wrapped around the tilt pulleys 12 and 13, one end is connected to the tilt operation pulley 11, and the other end is connected before and after the support shaft 31 of the camera fixing unit 9. When the pulley 11 for tilt operation is rotated, the tilt angle of the camera 18 changes.

For example, when the tilt operation shaft 19 is rotated clockwise in FIG. 2, the tilt wire rope 14 connected to the rear side of the support shaft 31 of the camera fixing unit 9 is pulled, and the camera fixing unit 9 is rotated. The camera 18 turns upward as the rear side of the camera tilts down.

At this time, since the tilt wire rope 14 connected to the front side of the support shaft 31 of the camera fixing portion 9 is sent out by the rotation of the tilt operation pulley 11, the front side of the camera fixing portion 9 can follow ascending.

When the tilt operation shaft 19 is rotated counterclockwise in FIG. 2, the tilt wire rope 14 connected to the front side of the support shaft 31 of the camera fixing unit 9 is pulled, and the tilting operation shaft 19 is rotated in front of the camera fixing unit 9. The camera 18 points downward as the side tilts down.

Also, when the telescopic pole 30 is reduced to the contracted state shown in FIG. 4, the distance from the camera fixing part 9 to the tilt pulley 13 provided at the lower part of the middle pole 2 is equal to the travel distance when the telescopic pole 30 is reduced as shown in FIG. Although it is reduced, it is provided above the lower pole 1 from this tilt pulley 13. Since the distance to the tilt pulley 12 is increased, the tilt wire rope 14 is not loosened. Therefore, the tilt angle of the camera can be changed by operating the tilt handle 21 even in the contracted state, as in the extended state.

In the camera pedestal, the carrier 22 can be horizontally moved by the moving device 43 provided with the casters 17, so that the camera 18 can also be horizontally moved to an arbitrary photographing position.

In this camera pedestal, since the tilt wire rope 14 is directly connected to the camera fixing portion 9, as shown in FIGS. 6 and 7, as the tilt angle increases, the upper pole 3 and the tilt pole become larger. The distance from the wire rope 14 decreases, and the amount of change Δ の in the tilt angle with respect to the amount of vertical movement h of the tilt wire rope 14 increases.

That is, as the tilt angle increases, the amount of operation of the tilt handle 21 and the amount of change in the tilt angle of the camera 18 become less proportional.

Further, as shown in FIGS. 8 and 9, since the center of gravity G of the camera 18 is separated from the support shaft 31, when the tilt angle Θ is increased, the camera 18 is returned to a horizontal position, so that a large operation force is required. In order to equalize this operation force, a counterweight 33 is provided on the tilt handle 21 as shown in FIG. 10, or a spring is mounted around the support shaft 31 of the camera fixing part 9 as shown in FIG. Considering the possibility of installing a balance mechanism 34 with 35 The total weight increases when the counterweight 33 is provided, and the mass around the camera 18 increases when the balance mechanism 34 is provided. Need to be done.

Therefore, in order to deal with these points, it is preferable to adopt a configuration as shown in FIGS.

Here, a camera tilt pulley 32 having the same diameter as the tilt operation pulley 11 is fixed to the camera fixing unit 9 so as to be rotatable about the support shaft 31, and one end of the front and rear tilt wire ropes 14 is used for tilt operation. The other end of the tilt wire rope 14 is connected to the upper portion of the camera tilt pulley 32 in a state where the camera 18 is horizontal, respectively.

Further, the camera fixing portion 9 is formed by being bent to the lower right side, and the camera 18 is fixed on the right side of the upper pole 3 at a position where the center of gravity G is on the axis of the support shaft 31.

With this configuration, since the tilt operation pulley 11 and the camera tilt pulley 32 have the same diameter, the rotation angle of the tilt operation pulley 11 and the tilt angle of the camera 18 become equal, and Even if the tilt angle changes, the distance between the upper pole 3 and the tilt wire rope 14 does not change, so that the load applied to the tilt wire rope 14 is constant regardless of the tilt angle of the camera 18, improving operability. I do.

Further, since the camera 18 is fixed to the camera fixing portion 9 at a position where the center of gravity G is on the axis of the support shaft 31, even if the tilt angle of the camera 18 changes, the operating force of the tilt handle 21 is constant. Therefore, it is not necessary to provide the counterweight 33 and the balance mechanism 34, etc., and it is possible to lighten the pedestal. In this camera pedestal, the force caster 17 having four casters 17 can be turned to the moving device 43 respectively. As shown in FIG. 15, when the casters 17 are aligned in the same direction as shown in FIG. 15 and the movement is started from a state, the direction of each caster 17 is aligned with the direction intended by the photographer. Goes in a direction different from the photographer ’s intention

[0027] Therefore, when shooting while moving, it may not be possible to shoot a video as intended by the photographer.

In such a case, as shown in FIGS. 16 to 18, it is preferable to lay the track 38 in accordance with the movement route intended by the photographer and use the moving device 41 provided with the track running wheels 37. In the carrier 22 of the camera pedestal shown in FIG. 16, moving device mounting brackets 42 are fixed on all sides similarly to the one shown in FIG. The moving device 41 has an adapter 33 fixed to the two moving device mounting brackets 42 using the handle 39 of the level adjustment mechanism 16 and a male screw at the lower portion. Around a rotatably mounted vertical support shaft 34, a wheel stay 35 having an internal thread that is screwed to the male screw of the support shaft 34, and a wheel stay 35 that is internally screwed to the male screw of the support shaft 34. It comprises a lock handle 36 for locking the shaft, a height adjustment handle 40 attached to the upper end of the support shaft 34, and a track running wheel 37 attached to the front and rear ends of a wheel stay 35.

When photographing using the camera pedestal, the photographer first lays a track 38 in accordance with the movement path intended by the photographer, and places the camera pedestal on the track 38. . Next, in order to align the height of the wheel stay 35, hold the height adjustment handle 40, rotate the hook handle 36 counterclockwise in plan view, and connect the male screw at the lower part of the support shaft 34 to the wheel The table 35 is made rotatable.

Then, when lowering the height of the wheel stay 35, the height adjustment handle 40 is rotated counterclockwise in plan view, and when increasing the height of the wheel stay 35, the height adjustment handle is used. Rotate 40 clockwise in plan view to align the heights of the four wheel stays 35. After that, the height adjustment handle 40 is grasped, and the lock handle 36 is rotated clockwise in a plan view to fix the support shaft 34 and the wheel stay 35.

When the camera pedestal travels on the track 38, each of the wheel stays 35 rotates around the support shaft 34 in the direction of the track 38 and changes direction. Navigate the path of exactly.

Therefore, when photographing while moving, it is possible to capture an image as intended by the photographer.

In the camera pedestal, a moving device mounting bracket 42 similar to that shown in FIG. 1 is fixed to the carrier 22 on all sides, so that the moving device 41 is provided with a caster as necessary. If it is replaced with the moving device 43, it can be used on the floor outside the orbit. Industrial potential

[0032] The camera pedestal of the present invention is easy to operate, can safely perform photography from a high place even in a narrow place, and is lightweight and inexpensive.
