The upper hemisphere 1 and the lower hemisphere 2 are horizontally separated from each other and the lower hemisphere 2 is formed larger than the radius of the upper hemisphere 1. [ That is, the upper hemisphere 1 is of a shape in which the lower portion is removed with respect to the horizontal center line, and the upper hemisphere 2 is formed with the upper portion removed with respect to the horizontal center line. At this time, the upper hemisphere 1 is formed with a fastening portion 1a on its upper portion.

The radius of the lower hemisphere 2 is preferably larger than that of the upper hemisphere 1 by 2/100 to 10/100 mm (H).

The upper hemisphere 1 and the lower hemisphere 2 also have a coefficient of friction of the surface of the lower hemisphere 2 in order to facilitate rotation of the upper hemisphere 1 with respect to the lower hemisphere 2, And the surface of the lower hemisphere 2 can be made rougher.

As a result, the difference in frictional force acting on the lower hemisphere 2 and the upper hemisphere 1 is further increased, thereby improving operability.

4 and 5, the multifunctional ball B for a ball head having a panoramic function according to the present invention has a seating groove (not shown) at a position where the upper hemisphere 1 and the lower hemisphere 2 are in mutual contact with each other, 3 are formed, and the sliding member 4 is inserted into the seating groove 3. [ At this time, bearings, bushes, washers and the like are applied to the sliding member 4, and plastic bearings, rolling bearings, thrust bearings and the like are applied as bearings, and plastic materials are applied to the bushes and washers.

6 to 8, a ball head 40 to which a multi-function ball for a ball head having a panoramic function according to the present invention is applied includes a housing 41, a ball B, a top sheet 43, A ball seat 45, a feed cam 47, and a ball head knob 49.

An annular step 41a having a diameter smaller than the diameter of the ball B is formed in the housing 41 so that the ball B is inserted into the housing 41 and the ball B is prevented from escaping from the upper part . At this time, a spherical surface coinciding with the upper hemisphere 1 of the ball B is formed in the annular step 41a.

The ball B has the same structure as described above. At this time, the upper hemisphere 1 and the lower hemisphere 2 of the ball B are assembled into the housing 41 in a mutually coupled state so as to be rotated in the housing 41.

The top sheet 43 is provided on the upper end of the ball B and the spherical surface whose inside coincides with the upper hemisphere 1 of the ball B is concave.

The ball seat 45 is formed with a concave spherical surface whose upper portion coincides with the lower hemisphere 2 of the ball B. The lower portion of the ball seat 45 is formed with an inclined surface 45a inclined downward at both sides from the center.

Then, the conveyance cam 47 is slantedly in contact with the ball seat 45 to move the ball seat 45 up and down. The feed cam 47 is divided into two parts corresponding to the inclined surfaces 45a formed on both sides of the lower portion of the ball sheet 45. Each of the feed cams 47 is connected to the stud bolt 49 of the ball head handle 49 49b.

The ball head knob 49 is composed of a knob 49a and a stud bolt 49b to move the feed cam 47 left and right.

The ball head knob 49 is finely adjusted to perform a panoramic function and a panning function in a state where the ball B is assembled to the ball head 40. [

7, when the ball B is positioned horizontally, the ball seat 45 is fixed to the lower hemisphere 2, and the upper hemisphere 1 is fixed to the top sheet 43. As shown in FIG.

8, when the ball B is bent, a part of the ball seat 45 and the top seat 43 fix the lower hemisphere 2 and the ball seat 45 and the top seat 43 Is fixed to the upper hemisphere 1.

Since the radius of the upper hemisphere 1 is small, frictional force acts differently due to the difference in contact area, so that the lower hemisphere 2 is fixed and a point at which the upper hemisphere 1 is rotated is generated. Particularly, as the ball B tilts, the lower hemisphere 1 having a larger diameter comes into contact with the top sheet 43 and the frictional force increases.

Meanwhile, the ball head 40 to which the multi-function ball for the ball head having the panorama function according to the present invention is applied, deletes the configuration such as the disk which performs the panning function in the conventional lower part.

The multi-function ball B for a ball head having a panoramic function according to the present invention can be applied not only to the ball head 40 shown in the drawings but also to the clamping system shown in U.S. Patent Application Publication No. 2006-0175482, It is applicable to all ball heads equipped with balls and locking balls.

Hereinafter, the operation of the ball head to which a multi-function ball for a ball head having a panoramic function according to the present invention is applied will be described in detail with reference to the accompanying drawings.

9 and 10 are diagrams for explaining the operation of a ball head to which a multi-function ball for a ball head having a panoramic function according to the present invention is applied.

First, a clamp is engaged to fasten the camera C to the fastening portion 1a provided on the upper hemisphere 1 of the ball B.

Then, a tripod is coupled to the bottom surface of the housing 41.

The ball B is restrained by the frictional force between the ball seat 45 and the top sheet 43 by moving the feed cam 47 by using the ball head knob 49 to raise the ball seat 45 .

9, when the panoramic function and the panning function are to be performed while the camera C is horizontally fixed, the ball seat 45 is adjusted to the lower hemisphere The upper hemisphere 1 is fixed and the top sheet 43 is fixed to the upper hemisphere 1. Due to the difference in the radii, A rotation point is generated.

In this state, when the photographer rotates the camera C horizontally, only the upper hemisphere 1 connected to the clamp is rotated, so that the panorama function and the panning function can be performed while maintaining the horizontal composition with the upper hemisphere 1 alone.

10, the photographer rotates the ball B to fix the camera C vertically and then moves the conveyance cam 47 using the ball head knob 49 to move the ball sheet 45 to the position shown in FIG. The ball B is restrained by the frictional force between the ball seat 45 and the top sheet 43. As a result,

In order to perform the panoramic function and the panning function in this state, the ball seat 45 and the top sheet 43 on the right side in the drawing fix the lower hemisphere 2 when the ball head knob 49 is finely adjusted, Since the ball seat 45 and the top sheet 43 on the upper left side fix the upper hemisphere 1 and the radius of the upper hemisphere 1 is small, the frictional forces are different from each other due to the difference in contact area, And a point at which the upper hemisphere 1 is rotated is generated. At this time, when the ball B is bent in the 90 占 direction, the fastening force is further increased, and the stability is excellent.

That is, when the camera is bent in the 90 ° direction, its center of gravity moves away from the center of the ball (B) and falls with a larger force, which in turn increases the frictional force.

In this state, when the photographer rotates the camera C vertically, only the upper hemisphere 1 connected to the clamp is rotated, so that the panorama function and the panning function can be performed only by the upper hemisphere 1.

In addition, when the camera C, the lens, and the like are mounted, the frictional force of the lower hemisphere 2 is greater due to the weight thereof, so that the lower hemisphere 2 is fixed and the rotation of the upper hemisphere 1 The lower hemisphere 1 having a larger diameter comes into contact with the top sheet 43 as the ball B tilts and the frictional force is increased so that it is possible to prevent the accident have.

In addition, since the panoramic function and the panning function according to the present invention are integrated into the ball B, the configuration of the normal panning portion and the panoramic portion can be eliminated, and the center of gravity of the camera is remarkably lowered, There is no panning configuration unfavorable to vibration, and the panning can be locked with a higher fastening force, so that the vibration suppression performance is enhanced, the sharpness of the image is greatly improved, and the ball head structure can be simplified and lightened.

In order to facilitate fixing of the upper hemisphere 1 and the lower hemisphere 2 when the ball head 40 is locked and smooth the rotation in the panning operation, Can be applied. That is, as shown in FIG. 5A, the plastic washer 4, which also serves as a bearing, can be inserted into the separation surface to enable smooth rotation. When the ball head 40 is locked, the plastic washer is compressed, The frictional force provides additional frictional force to prevent rotation.

5 (b), a collet-type plastic bush 4 is installed in a state of enclosing the shaft 5 protruding from the upper hemisphere 1 or the lower hemisphere 2 The plastic bush 4 compresses and fixes the shaft 5 to restrict the rotation of the upper hemisphere 1 and the lower hemisphere 2 when the ball head 40 is locked.

5 (c), when the upper hemisphere 1 and the lower hemisphere 2 are brought into close contact with each other according to the locking, the plastic bush 4 having the second inclined surface 4a It may have a structure for compressing and fixing the shaft 5 protruding from the upper hemispherical bulb 1 or the lower hemisphere 2.

5 (d), the rolling bearing 4 is installed between the shaft 5 protruded from the lower hemisphere 2 and the shaft groove 6 of the upper hemisphere 2, You can also get a structure that allows you to

5 (e) to 5 (g), when the thrust bearing 4 is inserted for smooth rotation of the upper hemisphere 1 and the lower hemisphere 2, the upper hemisphere 1 The rotational locking of the ball B is caused by the force of the ball seat 45 and the ball seat 45 outside the ball pressing the ball B It depends on the friction force.
