The present invention relates to an angle-variable support for use as a support for, for example, a photographing device such as a camera or an illuminating device such as an electric stand.

For example, in the case of supporting a camera with a conventional supported object, the camera is fixed to a mounting table installed on the upper three legs of the spherical bearing bearing, and then the camera is placed before or after the spherical bearing. The camera was rotated in the circumferential direction to adjust the angle of the camera to an arbitrary position, and the spherical bearing was fixed by rotating a lever or a fastening screw.

However, in the case of the structure in which the spherical body addressed to the mounting table is fixed by the rotation operation of the lever or the fastening screw as described above, loosen the lever or the fastening screw to release the spherical body, and then move the camera. After turning the ball in any direction of the circumference or the circumference, and tightening the lever or the fastening screw again, it is possible to change the direction of the camera quickly in a random direction by touching a lot of hands for fixing and releasing the spherical body. There was a problem that could not be done.

Moreover, since the tip portion of the pressing portion or the fastening screw addressed to the lever is pressed against the slippery rigid body circumference of the metal sphere, sufficient frictional resistance cannot be obtained to fix the sphere in place. Or the spherical body is easily rotated along the circumferential surface even if the fastening screw is tightened strongly, there is a problem that the camera, etc. fixed to the mounting table is slid due to its own weight and vibration.

The main purpose of this paper is to make the spherical body fixed by the one-touch operation to operate only the release ring by operating the fixing ring to separate the pressing pad from the sphere. An object of the present invention is to provide a variable angle support that can quickly and variablely adjust a supported object to any room.

Another object of this paper is to provide a friction term, because the locking projections are formed on the spherical body when the spherical body is fixed to the pressing pad that presses the spherical body integrally so that the spherical body is fixed to the spherical body. SUMMARY OF THE INVENTION An object of the present invention is to provide an angle-variable support that can reliably prevent rotation of a supported object such as a lighting apparatus due to its own weight or vibration and can be firmly fixed in a variable arbitrary direction.

Another object of the present invention is to form a concave-convex surface on the spherical body pressing surface of the pressing pad, and to provide an angle variable support that can obtain stronger frictional resistance than when fixing the sphere in place.

Another object of this paper is to form concave fitting parts and convex fitting parts in engagement with the contact between the concrete holding zone and the base, and the concrete holding zone and the base rotate in the conical direction when the release ring engages the engagement operation. An angularly variable support can be reliably prevented.

Another object of the present invention is to form cams on the axially opposite surfaces of the release ring and the spherical retainer, respectively, by releasing the engagement means, which are concave and convex fits, by rotating only the release ring. It is an object of the present invention to provide an angle variable support that can be smoothly and easily performed.

This paper maintains the spherical body made of elastic body in the cylindrical sphere holding unit so that it can be rotated, and the inside of the fastening part and the concrete holding part which guided the axis to the spherical body through the opening cut in the upper part of the concrete holding part. Pressing pads are formed on the bottom surface of the bottom of the concrete holding portion and the pressing pad formed with a concave surface corresponding to the spherical main surface, and the pressing pad penetrates up and down through the base between the bottom of the concrete holding portion and the base and the pressing portion. Coil spring that pushes the pressure pad toward the spherical body by opening the pad between the shaft and the bottom of the concrete holding part and the pressure pad which integrally formed the locking projections that squeeze the main surface of the sphere at the tip. And engagement means and concrete oil formed on each joining surface joined to the bottom and the base of the concrete holding portion to engage the bottom and the base at the time of joining. It is characterized in that the angle variable support having a release ring for loosely fitted to the outer peripheral surface of the branch and the base, the cam is released to release the engagement means.

According to this proposal, the engagement means formed in the joint between the concrete holding portion and the base by operating the release ring in the disengaging direction are separated from each other by a cam, and at the same time, the pressing pad and the locking protrusion fixed integrally with the base are formed on the spherical body. Release the spheres and then rotate the spheres in the front, back, or circumferential direction, and then change the supporting object such as a camera or lighting fixture fixed to the fastening part in any direction, and then engage the release ring. Therefore, the engagement means at the joint between the base and the concrete holding part are engaged with each other by the elastic force of the coil spring, and at the same time, the spherical body is pressed by the pressing pad and the locking projection, and the spherical body and the supported object are changed to the corrected position. Fix it.

According to the present invention, there are excellent effects as follows.

(1) The fixing of the spherical body is released by the pressing pad and the locking projection only by operating the release of the locking ring, and the pressing pad and the locking stone are caused by the elastic force of the coil spring when the locking ring is engaged. Since the machine is automatically pressed onto the sphere, the operation of turning and tightening with a lever or a fastening screw is unnecessary as in the conventional art. The fixation and release of the sphere can be easily performed by only one touch operation. The direction of the supported object such as a camera or a lighting fixture fixed to the fastening part can be changed quickly.

(2) In addition, during the engagement operation of the fixing release ring, the main surface of the spherical body in which the locking end of the shaft is made of an elastic body is pushed up from the bottom. Because of this, it is possible to prevent the supported object from sliding due to the weight or vibration of the supported object.

(3) Further, in the engagement operation of the fixing release ring, the engagement means provided in the joint portion of the bottom side and the base side is engaged, whereby the position slip due to the relative rotation between the concrete holding part and the base can be prevented.

(4) In addition, in the case where the concave-convex surface is formed at a predetermined portion of the pressing pad to which the spherical body abuts, the concave-convex surface condenses the spherical body main surface when fixing the spherical body, thereby preventing the spherical body from rotating in the circumferential direction. The spherical body can be fixed more securely.

(5) In addition, the engagement means forms a concave fitting portion and a convex fitting portion of the structure engaged with the concrete holding portion and the base by engaging the concrete holding portion with the base, thereby sliding the position by the opposite rotation of the concrete holding portion and the base. The change can be prevented more reliably.

(6) In addition, when the upper and lower pairs of cams are formed on the opposite surfaces of the release ring, the concrete holding portion and the shaft as the cams, the concave fitting portion and the convex fitting portion are simply operated by rotating the fixing release ring. Since it can be disengaged with, the fixing release operation is simple and easy.

In addition, since it is pushed back of the long axis 22 by the reflecting force at the time of insertion, the toe part 19b which protrudes in the insertion hole 19a of the fitting body 19 to the engaging surface 22a which is erected on the long axis 22. ) Is engaged to fix the clamping width between the fitting body 19 and the clamper 20.

Next, when the direction of the camera 2 is changed in this fixed state, as shown in FIG. 5, the fixing release ring 18 is rotated to release the cam 12a of the concrete holding part 9 and the fixing release. By contacting each protruding part with the cam 18a of the melting ring 18, the coil spring 11 is spun and the concrete holding part 9 moves upward and the base 13 moves downward. The holding portion 9 and the base 13 are spaced apart, and the concave fitting portion 16 formed on the concrete holding portion 9 and the convex fitting portion 17 formed on the base 13 are axially extended. It is disengaged and the fixed state by this engagement of each tooth surface 16a and 17a is canceled | released.

At the same time, the pressing pad 10 which is addressed to the base 13 is spaced downward from the main surface of the spherical body 6, and the uneven surface 10a and the tip of the shaft 14, which are angled to the upper end of the pressing pad 10, are separated. The fixing state of the spherical body 6 is released by the support with the latching protrusion 14a which is formed.

In this release state, the screw shaft 7 protruding into the spherical body 6 is rotated along the longitudinal hole 9b formed in the upper portion of the spherical body 9, or the spherical body 6 itself is rotated. The spherical holding section 9 is rotated in the circumferential direction to change the camera 2 into an arbitrary room.

When the sphere holding part 9 is rotated, each projection 12b formed in each protruding part of the cam 12a and each recess formed in each protruding part of the cam 18a ( 18b) ... can be sequentially engaged, so that the concave fitting portion 16 and the convex fitting portion 17 can be detached, and at the same time, they can be kept engaged by being engaged with each other. .

After setting the direction of the camera 2, the cams of the concrete holding portion 9 and the unlocking ring 18 are rotated by rotating the unlocking ring 18 as shown in FIG. 3 from the state of FIG. (12a) (18a) and the protruding part of each cam (12a) (18a) and each of the bent portion of each of the cam (12a) (18a) in contact with the coil spring ( The spherical fitting portion 17 formed in the concrete holding portion 9 and the convex fitting portion 17 formed in the concrete holding portion 9 is pressed down by the elastic force of 11). ) Is fitted in the axial direction to fix the pivoting device by engagement of the angular surfaces 16a and 17a.

The locking protrusion 14a is pressed against the main surface of the spherical body 6, and the rotation of the spherical body 6 is performed in synergism by the friction between the uneven surface 10a and the locking protrusions 14a of the shaft 14. Strongly fasten.

In this way, the spherical body 6 is released by the pressing pad 10 only by the operation of rotating the release ring 18, and the engagement force of the release ring 18 is applied to the elastic force of the coil spring 11. Since the rotation of the spherical body 6 is automatically fixed by the pressing pad 10, the rotation and the physique operation such as a revolver or a fastening screw are unnecessary as in the related art, and the fixation and release of the spherical body 6 are fixed. It can be easily performed only by the one-touch operation of rotating the release ring 18, and there is an effect that the direction of the camera 2 fixed to the fastening portion 3 can be quickly and variably adjusted.

In addition, when fixing the spherical body 6, the concave-convex surface 10a and the engaging projections 14a formed on the pressing pad 10 are pressed onto the main surface of the spherical body 6, so that the spherical body 6 is Rotating in the circumferential direction is fixed by the uneven surface 10a, while locking in the locking projection 14a works effectively to rotate in the longitudinal direction of the spherical body 6 to fix the spherical body 6. By the synergistic effect between the uneven surface 10a and the locking projection 14a, frictional resistance can be obtained by a pressure force sufficient to fix the spherical body 6 in position, and the spherical body 6 can be moved to an arbitrary rotational position. ) Can be fixed.

As a result, when the said camera 2 is fixed to the fastening part 3 which speaks to the spherical body 6, the closed end by which the direction of the camera 2 changes abruptly by self weight or a vibration etc. can be prevented reliably. There is an effect that the camera 2 can be firmly fixed to any room that has been variablely adjusted.

In addition, since the concave fitting portion 16 and the convex fitting portion 17, which are respectively formed on the sphere holding portion 9 and the base 13, are engaged with each other to fit and fix each other, the direction of the camera 2 is maintained. Each tooth surface 16a, 17a, which is formed in the concave fitting portion 16 and the convex fitting portion 17, which is variable by the rotation of the portion 9, is respectively engaged in the axial direction to fit the sphere. The holding unit 9 and the base 13 have an effect of reliably preventing relative rotation caused by vibration or movement up and down.

In addition, since the concave fitting portion 16 and the plunging fitting portion 17 are released only by the operation of rotating the fixing release ring 18, the concrete holding portion 9 and the base 3 are fixed to the rotating position. And the outer circumferential surface of the concrete holding portion 9 and the base 13 as compared with the structure configured to allow the ring to be rotated, while the fixing release ring 18 can be rotated. The contact surface resistance against is reduced, and as a result, the fixation and release operation can be performed smoothly with a weak force.
