Description

[Detailed description of the invention] The present invention relates to an improvement of a horizontal rotation device for a pan head.
A seat 5 is provided with a protrusion 4 formed by a large diameter portion 2 and a small diameter portion 3 protruding from the upper surface of the seat 5. A concave groove 6 is drilled in the concave groove 6, and only when a rotating ring 7 is artificially applied with force, it is fitted into the concave groove 6 so as to be rotatable in the horizontal direction, and tightening pieces 8 are provided at both ends around the large diameter portion 2. .8' is fitted into the tightening ring 9 integrally projecting, and furthermore, an inverted parallel-shaped body 10 is rotatably attached to the protrusion 4, and a through hole is provided in the top wall of the inverted parallel-shaped body 10. 11 through the small diameter section 3
is protruded from the upper side of the ceiling wall, and a C-shaped ring 12 for preventing removal is fixed to this protrusion, and an engagement hole that is mutually engaged with the lower surface of the inverted parallel-shaped body 10 and the upper surface of the rotating ring 7 is provided. 13 and an engaging protrusion 14, and the tightening piece 8 of the tightening ring 9,
8′ is formed in the inner circumferential surface of the inverted parallel-shaped body 10.
5, and the tightening pieces 8, 8' are attached to the inverted parallel-shaped body 10.
The rotation of the inverted parallel-shaped body 10 is stopped by tightening with a tightening knob 16 screwed on the zero peripheral wall, and a horseshoe-shaped shaft bearing part 18 is integrally provided on the upper surface of the inverted parallel-shaped body 10, A shaft hole 19 is provided at the horizontal center of this shaft bearing portion 18, and a semicircular moving shaft hole 20 is placed on a circular line centered on the coaxial hole 19.
A rotary ring 22, 22' having a protrusion 21 integrally provided on the outer surface at both ends of the shaft hole 19 is fitted in the rotary ring 22, 22' so as to be rotatable in the vertical direction only when artificial force is applied. Separately, a camera etc. fixing stand 23 having a π shape is configured,
Both legs 24° 24' of this fixed base 230 are attached to the above shaft bearing 1.
Through-holes 25 and 25' are fitted on the outside of both side surfaces of the leg portions 24 and 24', and corresponding to both ends of the shaft hole 19, and through-holes 25 and 25' are formed through the legs 24 and 24'. The engagement groove 26 of the protrusion 21 provided on the outer surface of the rotating ring 22, 22' is on the inner surface of the edge.
are bored with one end continuous with the lower end edge of the leg portion 24.24', and the shaft hole 19, the rotary ring 22 button, and the through hole 25.
The shaft rod 27 with head 27' is inserted into 25', and the coaxial rod 27 is
Screw the nut 28 onto the tip of the shaft rod 27 and insert it into the shaft hole 19.
The through hole 25 is rotatable within the rotary ring 22 and the rotary ring 22.
25', and a ball head 29 is provided outside the head end of this shaft rod 21, and an operating handle 30 is attached to the ball head 29. Through holes 32, 32' are provided at locations corresponding to both ends of the moving shaft hole 20, and a tightening ring 33, 33' is inserted into the through holes 32, 32'.
The shaft rod 34 with head 34' is inserted into the inner diameter hole button of the tightening ring 33, 33' and the moving shaft hole 20, and the tightening nut 35 is screwed onto the tip of the coaxial rod 34. When the tightening nut 35 is tightened, the tightening rings 33 and 33' break off both sides of the shaft bearing part 18, making it impossible for the shaft rod 34 to move within the moving shaft hole 20, and then tightening the tightening nut 35 again. When the tightening rings 33 and 33' are loosened, the buckling of the tightening rings 33 and 33' on both sides of the shaft bearing part is eliminated, allowing the shaft rod 34 to move within the moving shaft hole 20. When the locking knob 16 is loosened, the fixing base 23 is moved horizontally, and when the tightening nut 35 is loosened, the fixing base 23 is moved vertically, and both the tightening knob 16 and the tightening nut 35 are loosened. When this happens, the fixed base 23 can be moved in all directions.

As described above, the present invention constitutes a seat 5 having a protruding pillar 4 formed by a large diameter portion 2 and a small diameter portion 3 projecting from the upper surface, and this seat 5.
A groove 6 is bored around the base end of the large diameter portion 20 on the top surface, and a rotary ring 7 is fitted into the groove 6 so as to be rotatable in the horizontal direction. A tightening ring 9 having integrally protruding tightening pieces 8 and 8' is fitted, and an inverted parallel-shaped body 10 is rotatably mounted on the protrusion 4, and the inverted dish-shaped body 10 is
The small diameter portion 3 protrudes to the upper side of the ceiling wall through a through hole 11 provided in the ceiling wall, and a C-shaped ring 12 for preventing removal is fixed to this protrusion, and the tightening ring 9 is also tightened. The fastening pieces 8, 8' are inserted into the U-shaped recesses 15 formed on the inner peripheral surface of the inverted parallel-shaped body 10, and the fastening pieces 8, 8' are screwed onto the circumferential wall of the inverted parallel-shaped body 100. Since the rotation of the inversely parallel shaped body 10 is stopped by tightening the tightening knob 16, the fixing base 23 can be rotated horizontally from side to side by loosening the tightening knob 16, and Of course, the rotating ring 7 can be tightened to stop the rotation, but in particular, in the present invention, the rotating ring 7 can be inserted into the groove 6 on the upper surface of the pedestal 5, and the rotating ring 7 can be artificially tightened. An engagement hole 13 and an engagement protrusion 14 that are rotatable only when a force is applied and that are mutually engaged with the lower surface of the inverted parallel-shaped body 10 and the upper surface of the rotating ring 7.
Because of this provision, when the tightening knob 16 is loosened and the fixed base 23 is rotated horizontally from side to side, the brake is applied by the rotating ring 7 and the rotation is performed only by the amount of the artificially applied force, making it extremely easy to use. It has the effect of being easy to use.
