Tilt operation is installed on lower floor's bar 1 with axle 19 by the tilt operation vertical with axle center Y swingably with pulley 11.In Fig. 3, tilt operation (is seen as left-hand side from the cameraman's side that is positioned at the rear) with axle 19 in right side side extends, and is equipped with at its leading section to make tilt operation rotate, carry out the inclination handle 21 of tilt operation with pulley 11 with axle 19 and tilt operation.

And, be provided with video camera near with axle 19 with display 24 in the tilt operation of lower floor's bar 1.

Lifting handle 20 is installed on middle level bar 2, is used for changing the height of video camera 18 and the direction of video camera 18 by making 2 liftings of middle level bar, rotation.

The bar support portion 15 of the base end part of lower floor's bar 1 is provided with permanent load spring 5.This perseverance load spring 5 is used to offset the load of middle level bar 2, upper strata bar 3 and video camera 18, for example, can use コ Application スト Application (registered trade mark) spring of market sale etc.

As shown in Figure 5, be provided with lifting on the top of lower floor's bar 1 with pulley 6, hang on pulley 6 in this lifting and be wound with middle level bar lifting and be connected with cable wire 7, one ends and the perseverance spring 5 of loading, the other end is connected with the bottom of middle level bar 2.

Be provided with lifting on the top of middle level bar 2 with pulley 10, hang on pulley 10 in this lifting and be wound with upper strata bar lifting usefulness cable wire 8, the one end is connected with the bar support portion 15 of the base end part of lower floor bar 1, and the other end is connected with the bottom of upper strata bar 1.

And, be provided with pulley 12 in the front and back on the top of lower floor's bar 1, also be provided with pulley 13 in the front and back of the bottom of middle level bar 2, hang respectively on

pulley

12,13 around tilting in this inclined back and forth with cable wire 14, one end is connected with pulley 11 with tilt operation, and the other end is connected with the front and back of the fulcrum 31 of video camera fixed part 9.

Utilize under the situation that this pedestal for camera photographs, the cameraman at first carries out the horizontal adjusting of carriage 22 with horizontal adjusting mechanism 16, bar support portion 15 can be horizontally rotated, and expansion link 30 can be flexible in vertical direction.

When changing the height of video camera 18, lifting is manually carried out in lifting handle 20 utilizations.Middle level bar lifting is hung around the lifting on the top of lower floor's bar 1 and uses on the pulley 6 with cable wire 7, one end is connected with permanent load spring 5, the other end is connected with the bottom of middle level bar 2, and, upper strata bar lifting is hung around the lifting on top of middle level bar 2 with on the pulley 10 with cable wire 8, an end is connected with the bar support portion 15 of the base end part of lower floor bar 1, and the other end is connected with the bottom of upper strata bar 1, therefore, the lifting distance of video camera 18 is the twice of the displacement of lifting handle 20.

The gravity that acts on video camera 18, video camera fixed part 9, upper strata bar 3 is applied to upper strata bar lifting with on the cable wire 8, and its tension force is supported with pulley 10 by lifting.Though the upper strata bar lifting of being supported with pulley 10 by this lifting is applied on the middle level bar lifting usefulness cable wire 7 with the tension force of cable wire 8 and the gravity that acts on the middle level bar 2 that comprises lifting handle 20, but owing to always be applied with certain force of strain on cable wire 7 by the perseverance spring 5 of loading in middle level bar lifting, above-mentioned power is offset, therefore, need not to make expansion link 30 flexible with very big power.

Because lower floor's bar 1 is provided with video camera with display 24, though therefore video camera 18 is hoisted move after, also can easily confirm the image of photographing.

When changing the direction of video camera 18, manual rotation and lifting handle 20.

Since utilize rotating mechanism 23 to make expansion link 30 with 15 rotations of bar support portion, therefore, 18 anglecs of rotation that horizontally rotate lifting handle 20 of video camera.

When changing the angle of inclination of video camera 18, manual operation inclination handle 21 rotates tilt operation pulley 11 with tilt operation axle 19.

Be hung around with on the

pulley

12,13 with cable wire 14 owing to tilt, one end is connected with pulley 11 with tilt operation, and the other end is connected with fulcrum 31 front and back of video camera fixed part 9, therefore, in case tilt operation is rotated with pulley 11, then can change the angle of inclination of video camera 18.

For example, in Fig. 2, in case tilt operation axle 19 is rotated to clockwise direction, the inclination that is connected with the rear side of the fulcrum 31 of video camera fixed part 9 is stretched with 14 of cable wires, the rear side reduction crustal inclination of video camera fixed part 9, and therefore, video camera 18 is up.

At this moment, because the inclination that is connected with the front side of the fulcrum 31 of video camera fixed part 9 is sent by the rotation of tilt operation with pulley 11 with cable wire 14, therefore, the front side of video camera fixed part 9 can be along with lifting.

In Fig. 2, in case make tilt operation axle 19 to counterclockwise rotating, the inclination that is connected with the front side of the fulcrum 31 of video camera fixed part 9 is stretched with 14 of cable wires, the front side reduction crustal inclination of video camera fixed part 9, and therefore, video camera 18 is down.

And, make expansion link 30 from elongation state shown in Figure 1 when deflated state shown in Figure 4 shortens, inclination from video camera fixed part 9 to the bottom that is arranged on middle level bar 2 has only reduced the amount of displacement with the distance of pulley 13, but increased the distance of using pulley 12 from this inclination with pulley 13 to the inclination on the top that is arranged on lower floor's bar 1, therefore, tilt can not relax with cable wire 14.Therefore, also identical even under deflated state with elongation state, by operation inclination handle 21, can change the angle of inclination of video camera.

Therefore pedestal for camera, can make video camera 18 be moved horizontally to camera positions arbitrarily owing to can move horizontally by the mobile device 43 with carriage 22 and scroll wheel 17.

In addition, in this pedestal for camera, directly be connected with video camera fixed part 9 with cable wire 14 owing to tilt, therefore, as Fig. 6, shown in Figure 7, along with the angle of inclination increases, upper strata bar 3 and inclination reduce with the distance between the cable wire 14, and relative tilt increases with the amount of movement h of cable wire 14 above-below directions, the variation delta θ at angle of inclination.

That is, along with the increase at angle of inclination, the variable quantity at the angle of inclination of the operational ton of inclination handle 21 and video camera 18 loses ratio.

And,,, therefore,, then make video camera 18 level of getting back to need big operating physical force in case tilt angle theta increases because the center of gravity G of video camera 18 leaves fulcrum 31 as Fig. 8, shown in Figure 9.

In order to make this operating physical force even, can be as shown in figure 10, can consider on inclination handle 21, to be provided with counterweight 33, or as shown in figure 11, balanced controls 34 based on spring 35 are set in the front and back of the fulcrum 31 of video camera fixed part 9, but if counterweight 33 were set then the overall weight increase, if balanced controls 34 are set then the quality increase of video camera 18 peripheries, would need to increase the power of drawing in of the permanent spring 5 of loading.

Therefore, as countermeasure, be preferably formed as Figure 12～formation shown in Figure 14.

At this, be the center, will tilt to be rotatably mounted on the video camera fixed part 9 with the video camera of pulley 11 with fulcrum 31 with tilt operation with pulley 32 with diameter, inclined back and forth is connected with pulley 11 with tilt operation respectively with an end of cable wire 14, inclination is under the level at video camera 18 with the other end of cable wire 14 is connected with the top of video camera inclination respectively with pulley 32.

And, video camera fixed part 9 is bent to form to the lower right side, the position that video camera 18 is positioned in the right side side of upper strata bar 3, at center of gravity G on the axis of fulcrum 31 is fixed.

By such formation, because tilt operation tilts with pulley 32 same diameters with pulley 11 and video camera, therefore, tilt operation uses the rotational angle of pulley 11 to equate with the angle of inclination of video camera 18, and, even the angle of inclination changes, upper strata bar 3 and inclination can not change with the distance between the cable wire 14 yet, therefore, irrelevant with the angle of inclination of video camera 18, tilting with forming certain load on the cable wire 14, improved operability.

Because video camera 18 is positioned at fixed-site on the axis of fulcrum 31 at video camera fixed part 9 at center of gravity G, therefore, even the angle of inclination of video camera 18 changes, the operating physical force of inclination handle 21 also is certain, need not to be provided with counterweight 33 or balanced controls 34 etc., can realize lightness.

In this pedestal for camera, have four scroll wheels 17, because scroll wheel 17 can freedom rollably be supported on the mobile device 43 respectively, therefore, as shown in figure 15, if begin to move under the skimble-scamble state of the direction of scroll wheel 17, then the direction of each scroll wheel 17, was advanced to the direction different with the desirable direction of cameraman before the desirable direction of cameraman unified.

Therefore, one side moves under the situation of one side photography, can not photograph according to cameraman's intention.

In this case,, preferably lay track 38, use mobile device 41 with rail running wheel 37 according to the desirable mobile alignment of cameraman as Figure 16～shown in Figure 180.

On the carriage 22 of pedestal for camera shown in Figure 16, with shown in Figure 1 identical, mobile device installing rack 42 is fixedly installed on the four direction.And, mobile device 41 is by connector 33, vertical fulcrum 34, wheel support plate 35, lock handle 36, Height Adjustment handle 40 and rail running wheel 37 constitute, connector 33 utilizes the handle 39 of horizontal adjusting mechanism 16 to be fixed on two mobile device installing racks 42, vertical fulcrum 34 has external screw thread in the bottom, be installed in rotation on the end, front and back of connector 33, wheel has with the external screw thread of fulcrum 34 with support plate 35 twists the internal thread that closes, lock handle 36 lockings are twisted the rotation that the wheel that closes is used support plate 35 with the external screw thread of internal thread and fulcrum 34, Height Adjustment handle 40 is installed in the upper end of fulcrum 34, and rail running wheel 37 is installed in the front and back end of wheel with support plate 35.

Utilize under the situation that this pedestal for camera photographs, at first the cameraman lays track 38 according to the desirable mobile alignment of cameraman, and pedestal for camera is placed on the track 38.Then,, hold Height Adjustment handle 40, lock handle 36 is rotation counterclockwise to overlooking, but make the external screw thread of fulcrum 34 bottoms become the state that relative wheel rotates with support plate 35 for the height of unified wheel with support plate 35.

Afterwards, when the reduction wheel was used the height of support plate 35, making Height Adjustment handle 40 was counterclockwise to rotate to overlooking, when the rising wheel is used the height of support plate 35, make Height Adjustment handle 40 to overlooking to clockwise direction rotates unified four wheels height of support plate 35.Then, holding Height Adjustment handle 40, is the clockwise direction rotation with lock handle 36 to overlooking, a fixed pivot axis 34 and wheel support plate 35.

In case pedestal for camera is moved on track 38, each wheel is that rotate at the center, conversion direction with support plate 35 according to the direction of track 38, with fulcrum 34, and therefore, carriage 22 correctly moves to fixed course along track 38.

Therefore, one side moves under the situation of one side photography, can photograph according to cameraman's intention.

In addition, in this pedestal for camera, owing to be fixedly installed on the carriage 22, therefore at four direction with identical mobile device installing rack 42 shown in Figure 1, if with mobile device 41 and mobile device 43 exchanges, can on the floor beyond the track, use as required with scroll wheel.

Pedestal for camera processing ease of the present invention can be photographed in light weight and low price safely in narrow and small place from eminence.
