Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a small camera tripod that can be attached to the bottom of the camera and carried along with the camera.

[Prior art and problems to be solved] Conventional camera tripods are small and lightweight, and are separated from the camera when not in use, improving the mobility and operability of the camera during shooting. It is common practice to keep it unaffected.

Therefore, each time a tripod is used, it is inconvenient to attach the tripod to the camera.

The present invention solves the above-mentioned conventional problems, and when not in use, it can be left attached to the bottom of the camera body in a box shape as if it were part of the camera, and is easy to use. It is an object of the present invention to provide a tripod for a camera that can be placed in a state where it can be used.

[Means for Solving Problems] For this purpose, the present invention provides a tripod for a camera that is equipped with a pan head and a leg body, in which the pan head is in a substantially rectangular plate shape corresponding to the bottom of the camera, and when the legs are closed, the tripod is equipped with a camera tripod. The legs, which have almost the same shape, are connected to each other so that they can rotate and fold in half at their mutual ends, and the legs consist of a middle leg and left and right legs, and the middle legs are connected to the pan head tilt axis and the middle leg. The left and right legs are attached to the pan head so as to be rotatable and tiltable through the child fittings, and the pan head is automatically biased by an elastic body so as to be rotatable in the direction of opening the legs. The structure is such that the middle leg is automatically biased and attached to the middle leg so as to be able to freely rotate and open.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

The camera tripod according to this embodiment includes a pan head 1 for mounting a camera and legs 2 for supporting the pan head 1.

The pan head 1 is fixed to the bottom of the camera with a camera set screw 3. Here, the camera set screw 3 is inserted at a position corresponding to each model on the camera mounting surface 4 in order to be compatible with many types of cameras. A plurality of common mounting holes 5 are provided. Further, the pan head 1 is plate-shaped and has a substantially rectangular shape that can be adapted to the bottom of various cameras. It should be noted that this pan head can also be made into an attachment by having a shape that can be used only for a camera with a specific mechanism, and by reducing the number of mounting holes 5 to one.
Furthermore, although one camera set screw 3 is used here, it is also possible to use a plurality of camera set screws 3 to attach the camera at two or more points. Also,
A connecting piece 6 with the leg body 2 is provided on one end side of the pan head 1.

The legs 2 have substantially the same shape as the pan head 1 in the closed state, are rotatably connected to the pan head 1 at mutual ends, and can be folded into two. Specifically, the legs 2 are connected to the pan head 1 in the closed state.
A flat left leg 7 and a right leg 8 that have almost the same shape as
and a middle leg 9 whose distal end is stored in a recess formed by the left and right legs 7 and 8 when the legs are closed. Further, the left and right legs 7 and 8 are rotatably attached to the middle leg 9 via a leg mounting plate 10, and the middle leg 9 is rotatably attached to the connecting piece 6 of the pan head 1 via a core metal fitting 11. Installed.

To explain this in more detail, the left leg 7 is attached to the leg mounting plate 10.
The right leg 8 is rotatably attached by screws 14 to the through hole 12 on the left side and the through hole 13 on the right side at symmetrical positions.

In addition, the left and right legs 7 and 8 are rotated in the leg opening direction by the constricted portions 15 of the leg mounting plate 10, and rotated in the closed state by the side surfaces of the leg mounting plate 10. The rotation range is regulated by . That is, by being attached to the leg mounting plate 10 as described above, the left leg 7 and the right leg 8 can be moved to open and close left and right within one plane. On the other hand, the leg mounting plate 10
is rotatably attached to the middle leg 9 via a screw 16.

Therefore, the middle leg 9 is the left leg 7 in the vertical plane that includes the bisector of the left leg 7 and the right leg 8 in the open leg state.
and can rotate independently from the right leg 8.

Note that the rotation in the leg opening direction is handled by the base of the bifurcated part of the leg mounting plate 10, and the rotation in the leg closing direction is handled by the upper surface of the lower end of the leg mounting plate 10. The rotation range of each is regulated.

Further, the middle leg 9 is attached to the connecting piece 6 of the pan head 1 via the core metal fitting 11 as described above, and the leg body 2 having the above-described structure can be rotated and tilted relative to the pan head 1. It is movably pivoted and mounted.
That is, the upper end of the middle leg 9 is fixed to the head tilt shaft 17 in the horizontal direction when the legs 2 are in the open state and installed horizontally, and the head notch 17a of the head tilt shaft 17 is fixed to the upper end of the middle leg 9. On the other hand, the engaging protrusion 11a of the core metal fitting 11 can be brought into contact with a gap of a predetermined angle, and is pivotably supported so as to be tiltable within that angle.

The core metal fitting 11 also has a through hole 1 extending in a direction perpendicular to the vertical plane on which the middle leg 9 rotates.
8 is provided. Similarly, a slot 19 is provided in the center of the metal core 11. The core metal fitting 11 is rotatably attached to the connecting piece 6 of the pan head 1 by a knurled bolt 20 and a knurled nut 21 passing through the through hole 18.

In addition, the knurled nut 21 is the bolt 20
It is designed to be able to freely slide in the axial direction of the bearing, and to rotate integrally with the bearing around the axis.

Furthermore, a lock lever 22 is fixed to the head of the knurled bolt 20 so as to mesh with the knurl. This lock lever 22 fixes the movement of the pan head 1 around the knurled bolt 20. At the same time, the interval between the slots 19 of the core metal fitting 11 is reduced, and the movement around the pan head tilt axis 17 is also fixed, and by rotating in the opposite direction, these fixations are released.

Further, the middle leg 9 is urged to be automatically rotatable via a spring 23 as an elastic body.
This spring 23 is connected to the slot 19 of the core metal fitting 11.
The core metal fitting 11 is inserted into the inside and attached together with the core metal fitting 11 with knurled bolts 20, and by rotatably urging the core metal fitting 11, the middle leg 9 integrated with the core metal fitting 11 is rotationally urged. I'm starting to do that.

Also. Although not shown, a click portion is provided on the opposing surfaces of the connecting piece 6 of the pan head 1 and the middle leg 9, and once the middle leg 9 is in a position where it can support the pan head 1 in a horizontal state, the middle leg 9 can be rotated. I'm trying to get it to stop. The click portion is provided with a protrusion on one side and a protrusion that engages with the protrusion on the other side.

Further, the left and right legs 7, 8 are automatically biased against the middle leg 9 via springs 24, 25 as elastic bodies so as to be able to rotate freely. Specifically, the spring 24 is attached to the connection portion between the middle leg 9 and the leg mounting plate 10 with a screw 16, and urges the leg mounting plate 10 to be rotatable with respect to the middle leg 9. Both left and right legs 7 attached to
8 is rotationally biased. Further, the springs 25 are disposed between both side surfaces of the leg mounting plate 10 and the left and right legs 7 and 8, respectively, and bias the left and right legs 7 and 8 in the leg-opening direction.

Therefore, these springs 23, 24, 25 automatically bring the middle leg 9 and the left and right legs 7, 8 into the open state.

The middle leg 9 and both left and right legs 7 and 8 are kept in a closed state when not in use, and are folded in half on the bottom side of the pan head 1. A lock plate 26 is provided to maintain this folded state. Panhead 1
The connecting piece 6 is attached to the opposite end of the connecting piece 6. This lock plate 26 is slidably attached to the lower surface of the pan head 1, and is configured such that a locking piece 28 and an operating piece 29 are biased toward the end side via a spring 27. The locking pieces 28 of the lock plate 26 are engaged with engaging recesses 30 formed at the ends of the left and right legs 7, 8 to maintain the folded state.

Therefore, when in use, if the operating piece 29 of the lock plate 26 is pushed in the opposite direction, the lock plate 2
The locking piece 28 of 6 and the engagement recess 30 of both left and right legs 7 and 8
At the same time, the spring 23 automatically rotates the middle leg 9 in the direction of opening the legs.
In addition, the spring 24 automatically rotates the left and right legs 7, 8 in the direction away from the middle leg 9 via the leg mounting plate 10, and the spring 25 automatically rotates the left and right legs 7, 8 in the direction away from the middle leg 9. She makes him open her legs. In this case, the click portion positions the pan head 1 in a horizontal position.

Then, install it in this state and use the pan head tilt axis 17.
By using the knurled bolt 20 to determine the rotational position of the pan head 1 in the vertical plane and the front and back tilt angle, the lock lever 22 is tightened and fixed, and the device can be easily put into use. Further, the pan head 1 can also be used in a vertical position as shown in FIG.

[Effects of the invention] As explained above, the present invention provides a leg body that has almost the same shape as the pan head when the legs are closed, for a nearly rectangular plate-shaped pan head corresponding to the bottom of the camera, by attaching the legs to the ends of each other. Since it is connected so that it can be rotated and folded in half, it can be firmly fixed to the bottom of the camera and support the camera in a stable state, giving it a sense of unity with the camera, and also when not in use. In some cases, the device can be folded in half and left compactly attached to the bottom of the camera body, as if it were part of the camera.

In addition, the leg body is composed of a middle leg and left and right legs,
Since the middle leg is rotatably and tiltably attached to the pan head via the pan head tilt shaft and the core metal fitting, it is possible to easily adjust the front and rear and left and right angles of the camera.

Furthermore, the middle leg is automatically biased to be rotatable by an elastic body and attached to the pan head, and the left and right legs are automatically pivoted and opened relative to the middle leg via the elastic body. Since it is attached by applying force, the legs can be opened in a so-called one-touch operation, resulting in good operability.
