[Problem that the invention seeks to solve]

By the way, in order to stably support a camera with a tripod, it is necessary to keep the center of gravity of the camera low and the distance between the tripod and the ground to be large. There is a problem that the center of gravity cannot be lowered and the distance between the tripod and the ground cannot be made large, resulting in a lack of stability. In other words, in order to lower the center of gravity of the camera, it is necessary to tilt the grip body considerably, but in this case, the projected position of the center of gravity of the camera deviates from the approximate center of the pair of left and right legs that open in a "V" shape. , it becomes unstable. Furthermore, the length of the pair of left and right legs cannot be longer than the length of the grip body, and therefore, the ground contact interval of the tripod cannot be made significantly larger.

Furthermore, when using the grip, the pair of left and right legs are folded and housed in the grip body, making it difficult to grip.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a grip with a built-in tripod that is easy to hold when using the grip and is highly stable when using a tripod.

[Means for solving problems]

In order to achieve the above object, the present invention provides a grip which is rotatably disposed at the bottom of the camera and whose angle can be fixed between the angle when the grip is used and the angle when the tripod is used, which is tilted further forward of the camera than when the grip is used. a main body; and a pair of left and right legs that are at least partially slidably accommodated inside the grip body in the longitudinal direction of the grip body, and that are pulled out from the rear of the grip body and opened at a predetermined angle when the grip body is used on a tripod. It is characterized by consisting of.

[Effect]

According to the present invention, when the grip is used, the pair of left and right legs are slid into the grip body, so the hands do not touch the legs, making it easier to grip. In addition, when using a tripod, the grip body is tilted in front of the camera, and the pair of left and right legs are pulled out from the rear of the grip and opened at a predetermined angle, lowering the center of gravity of the camera and providing three points for contact with the ground. can be made larger.

〔Example〕

Preferred embodiments of the tripod built-in grip according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a side view of a video camera equipped with a built-in tripod grip according to the present invention, and shows a case where a built-in tripod grip 20 is used as a handgrip.

As shown in the figure, this video camera 10 is a VTR integrated type, and 12 is a photographic lens, 14 is an electronic viewfinder, 16 is a cassette holder, and 18 is a battery.

As shown in FIG.
It is removable from the bottom of the 0. That is, when attaching the built-in tripod grip 20 to the bottom of the video camera 10, the tripod screw 32 is positioned in the tripod mounting screw hole at the bottom of the video camera 10, and the positioning pin 33 is
is inserted into a detent recess (not shown) formed at the bottom of the video camera 10, and the tripod screw 32 is turned to be screwed into the tripod mounting screw hole.

The built-in tripod grip 20 mainly consists of a grip base 30 that is fixed to the bottom of the camera, a grip body 40 that is actually gripped, and a pair of left and right legs 50 and 50 when used as a tripod. .

In addition to the tripod screw 32 and positioning pin 33, the grip base portion 30 is provided with an angle locking mechanism 36 and a recording switch mechanism 38 for the grip body 40, which are rotatably disposed around a support shaft 34. .

As shown in FIG. 3, the angle lock mechanism 36 includes a slide member 3 that operates together with a lock release knob 36A (FIG. 2).
6B and a spring 36 that returns this slide member 36B.
C, lever 36D, claw portion 36E, and this claw portion 36E.
a spring 36F that biases in a direction to protrude; and a recess 42A provided on the grip body 40 side that engages with the claw portion 36E.
and sawtooth portions 42B.

Therefore, when the lock release knob 36A is moved to the right in FIG. 2 and the slide member 36B is moved in the direction of the arrow against the urging force of the spring 36C, one end of the lever 36D is pressed against the slide member 36B. The other end rotates clockwise, and the claw portion 36 resists the biasing force of the spring 36F.
Push up E. As a result, the claw portion 36E and the sawtooth portion 4
2B is disengaged, the lock is released, and the grip body 40 becomes rotatable.

When the grip main body 40 is rotated to a desired angle and then released from the lock release knob 36A, it is returned to its original position by the slide member 36B or spring 36C, and the claw portion 36E is protruded by the spring 36F and has a sawtooth. It engages with the shaped portion 42B, thereby fixing the angle of the grip body 40.

Note that when the claw portion 36E and the recess 42A of the grip body 400 are engaged, the grip body 40 is moved to the second position as shown in the figure.
This is the angle when using the grip (an angle tilted 30 degrees from the vertical direction toward the front of the camera). Further, when the claw portion 36E and the serrated portion 42B of the grip main body 40 are engaged, the grip main body 40 is used as a part of the tripod as described later, and the position where the claw 836E and the serrated portion 42B engage is used to fix the tripod. camera angle is set.

The recording switch mechanism 38 also includes a REC start button 38.
A and the spring 3 that returns this REC start button 38A.
8B, an actuation member 38C fixed to the REC start button 38A, a lever 38D rotated by the actuation member 38C, a click spring 38E that clicks the lever 38D, and an L' bar 38DI: Therefore, oN
It is composed of a REC start switch 38F that operates at 10FF.

Therefore, when the REC start button 38A is pushed beyond a certain dead zone, the lever 38D is rotated counterclockwise by the actuating member 38C, and the REC start switch 38F is pressed by the other end of the lever 38, and the REC start switch 38F is pressed.
It becomes N. Note that the REC start switch 38F is electrically connected to the camera body side via a connector (not shown).

On the other hand, when you release your finger from the REC start button 38A, the REC
The start button 38A and the actuating member 38C are returned to their original positions by the spring 38B, which causes the lever 38D to rotate clockwise and activate the REC start switch 38.
F becomes OFF.

Now, as described above, the grip body 40 is rotatably arranged with respect to the grip base part 30 by the support shaft 34, and also has a pair of left and right leg parts 50 as shown in FIG.
．． It has a storage section 44 in which a part of the storage device 50 is slidably stored. Note that 46 is a spring that fixes the leg portions 50 and 50 stored in the storage portion 44.

On the other hand, the leg portions 50.50 are pulled out from the rear of the grip body 40 as shown by the solid line in FIG. It is arranged so that it can be slid freely between the two positions. Further, the left and right pair of legs 50.50 are rotatably supported by a shaft 50A, and the legs 50, 50 are disposed between them.
A torsion spring 52 is provided which biases the opening direction of 0.50 (see FIG. 5). Therefore, when the legs 50.50 are pulled out a predetermined amount from the rear of the grip main body 40, the pair of left and right legs 50.50 are opened symmetrically by the torsion spring 52, as shown in FIG. Note that the opening degree of the pair of left and right leg portions 50 and 50 at this time is 30°.

That is, according to the built-in tripod grip configured as described above, when changing the built-in tripod grip from a state in which it can be used as a hand grip to a state in which it can be used as a tripod, as shown in FIGS. The main body 40 is tilted toward the front of the camera, and then the pair of left and right legs 50, 50 are pulled out from the rear of the grip main body 40. The drawn-out legs 50.50 are symmetrically opened at a predetermined angle by the torsion spring 52. As a result, the camera can be supported by the grip main body 40 and the pair of left and right legs 50.5003.

6 to 8 show other embodiments of the grip with a built-in tripod according to the present invention. FIG. 6 is a side view when the grip is in use, and FIGS. 7 and 8 are a side view when the grip is in use. They are a side view and a top view.

Note that this grip with a built-in tripod differs only in shape from the grip with a built-in tripod of the first embodiment described above, so members having the same mechanism are given the same reference numerals, and detailed explanation thereof will be omitted.

The main differences between the built-in tripod grip of the first embodiment and this built-in tripod grip are that a part of the leg portion 50 constitutes a part of the grip as shown in FIG. 6, and as shown in FIG. When pulling out the pair of left and right legs 50, 50, as shown in Fig. 2, the legs are pulled out upward without changing the angle downward midway.

Although the tripod built-in grip of this embodiment is removably attached to the bottom of the camera, the present invention is not limited to this, and may be integrally fixed to the bottom of the camera. Further, the angle lock mechanism and the recording switch mechanism are not limited to those of this embodiment, and various other mechanisms may be used.

By the way, when using the tripod built-in grip 20 as a tripod, it may be more stable as a tripod if it is attached to the bottom of the video camera 10 with the front and rear directions reversed or in any direction. On the other hand, positioning pin 3 that prevents rotation
If 3 is omitted, the video camera may rotate when used as an undergrip, making it unstable.

Therefore, we made the positioning pin that prevents it from rotating freely and retracts it, and when this positioning pin reaches a position other than the recess on the bottom of the video camera, it can be retracted to attach the built-in tripod grip to the video camera in any direction. It's convenient if possible.

Figure 9 is a sectional view showing the structure of the mounting part that allows the built-in tripod grip to be mounted in any direction;
It mainly consists of a tripod screw 60, a positioning pin 62, and a coil spring 64.

A disc-shaped knob 60A is fixed to the tripod screw 60, and by rotating the knob 60A, the tripod screw 60 can be rotated. Further, the positioning pin 62 is located between the tab/toro 6 that comes into contact with the bottom of the video camera and the plate 68 below it.
It is disposed so as to be movable in the vertical direction in the figure, and is biased by a coil spring 64 in the protruding direction (upward in FIG. 9).

When attaching the built-in tripod grip to the bottom of the video camera as an undergrip using the above mounting section, position the tripod screw 60 in the tripod mounting screw hole on the bottom of the video camera, and insert the positioning pin 62 into the screw hole formed on the bottom of the video camera. The tripod screw 60 is inserted into the stopper recess and screwed into the tripod mounting screw hole by turning the tripod screw 60 using its knob 60A.

On the other hand, when attaching the built-in tripod grip to the bottom of the video camera as a tripod, the mounting method is not limited to inserting the positioning pin 62 into the recess for preventing rotation as described above. It can be mounted in any direction, preferably in the direction that provides the most stability as a tripod. In this case, the positioning pin 62
contacts the bottom of the video camera and retracts against the biasing force of the coil spring 64, and the video camera is fixed to the tripod built-in grip only by the tripod screw 60.

〔Effect of the invention〕

As explained above, according to the tripod built-in grip according to the present invention, when the grip is used, the pair of left and right legs are slid and stored inside the grip body, so the hands do not have to touch the legs at all or hardly at all, making it easy to grip. There is an advantage. Also,
When using a tripod, tilt the grip body toward the front of the camera.
Since the pair of left and right legs are pulled out from the back and opened at a predetermined angle, the center of gravity of the camera can be lowered, and the three points of contact with the ground can be made thicker, making it a highly stable tripod. can be configured.
