However, since the knob of the fixing screw is provided near the horizontal rotation axis, and a heavy camera is attached and fixed to the tip side of the support shaft, when the knob is operated to loosen the fixing screw, the camera There is a risk that the spindle will fall down due to its own weight and break the camera.
Therefore, when tilting the camera to an arbitrary angle, be sure to press the tip of the support shaft with one hand so that the support shaft does not fall down, and operate the knob of the fixing screw provided near the horizontal rotation shaft with the other hand. As such, there is the hassle of having to operate with both hands.

  Therefore, the present invention has a technical problem to be able to tilt the support shaft to a desired angle without tilting the support shaft due to the weight of the camera even when operated with one hand.

In order to solve this problem, the invention of claim 1 is a camera stand that fixes a camera at an arbitrary inclination angle with respect to an object to be observed placed on a stage, and the camera is set at an arbitrary height. A stopper for stopping the swing of the support shaft is provided on the swing support portion that supports the support shaft to be swingably supported around the horizontal rotation shaft, and an operation element of the stopper is attached to the tip of the support shaft.

And a concave groove is provided at a position corresponding to the annular rib formed along the inner peripheral surface of the bearing hole, and the stopper is provided with an insulator having the annular rib as a fulcrum in the key groove, The operating rod inserted into the support shaft is moved forward and backward by screw feed of the operation element provided at the end of the support shaft, and the horizontal rotation shaft is pressed against the bearing hole by pressing and tilting one end of the lever, so that the support shaft can be arbitrarily set. It is configured to be fastened and fixed at an inclination angle of.

According to the camera stand of the present invention, the stopper for stopping the swinging of the support shaft is provided on the horizontal rotation shaft, and the operation element for the stopper is provided on the support shaft tip. The stopper can be loosened by operating the child, and the support shaft can be tilted to a desired angle as it is, and then the stopper operator can be tightened with the hand holding the tip of the support shaft to fix the support shaft.
In this case, as a stopper, an insulator having an annular rib formed along the inner peripheral surface of the bearing hole as a fulcrum is disposed in the key groove of the horizontal rotating shaft to which the support shaft is attached, and is inserted into the support shaft. If the operated rod is screw-fed by an operating element provided at the tip of the support shaft, one end of the lever is pressed and tilted, and the horizontal rotating shaft is pressed against the bearing hole and fixed to each shaft.

  In this example, the camera is mounted and supported at an arbitrary height in order to achieve the purpose of tilting the spindle to a desired angle without tilting the spindle due to the weight of the camera even when operated with one hand. A stopper operator for stopping the swinging of the support shaft is provided at the end of the support shaft.

  FIG. 1 is a side view showing an example of a camera stand according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is an explanatory view showing a main part.

  The camera stand 1 of this example is used to fix the camera C to an arbitrary inclination angle with respect to an object to be observed placed on the stage 2, and attaches and supports the camera C at an arbitrary height. A stopper S for stopping the swinging of the support shaft 3 is provided on the swinging support portion P that supports the pipe-shaped support shaft 3 to be swingable, and an operation element 5 of the stopper S is attached to the support shaft tip 3a. It is attached.

The swing support portion P includes a horizontal rotation shaft 4 that fixes the support shaft 3 and a bearing block 8 in which a bearing hole 9 that rotatably supports the horizontal rotation shaft 4 is formed. It is provided at the upper end of the fixed column 7 that is erected.
A key groove 4 a extending in the axial direction is formed on the peripheral surface of the horizontal rotating shaft 4, and a concave groove 4 b is provided at a position corresponding to the annular rib 10 formed along the inner peripheral surface of the bearing hole 9. ing.

In the stopper S, an insulator 11 having an annular rib 10 as a fulcrum is disposed in a key groove 4a of the horizontal rotating shaft 4, and a pipe-shaped operation rod 12 inserted through the support shaft 3 is provided at the support shaft tip 3a. When the spherical operation element 5 is screwed, one end 11a of the lever 11 is pushed down to tilt the lever 11 in the key groove 4a, and the horizontal rotary shaft 4 is pressed against the inner peripheral surface of the bearing hole 9 to The horizontal rotating shaft 4 is fixed to the bearing hole 9 by friction, and as a result, the support shaft 3 is fastened and fixed at an arbitrary inclination angle.
The operating element 5 is formed with a male screw 5a that engages with a female screw 3b formed at the support shaft tip 3a, and between the male screw 5a and the operating rod 12, and between the operating rod 12 and the lever 11. Are provided with spheres 13 and 14 for preventing the pressing force from being biased.

The above is one configuration example of the present invention, and the operation thereof will be described next.
In a state where the operating element 5 of the camera stand 1 is tightened, the lever 11 of the stopper 5 is inclined, and the horizontal rotating shaft 4 is pressed against the inner peripheral surface of the bearing hole 9 and fixed to the bearing hole 9 by the friction. As a result, the support shaft 3 is securely fastened and fixed at an arbitrary inclination angle.
In this state, if the camera C is fixed to the height adjustment bracket 15 attached to the support shaft 3 and adjusted to a desired height, the support shaft 3 is fixed by the stopper S. It will not fall over.

Next, in order to adjust the imaging angle, if the operator 5 is grasped with one hand and the screw is loosened, the pressing force of the operating rod 12 that has pressed the one short 11a of the lever 11 is weakened. The insulator 11 that presses 4 against the inner peripheral surface of the bearing hole 9 becomes free in the key groove 4a, and the horizontal rotary shaft 4 can rotate.
At this time, since the operator 5 at the tip 3a of the support shaft 3 is grasped with one hand, the support shaft 3 does not fall down by its own weight.

  Then, if the operator 5 is clamped with one hand while holding the operator 5 with one hand and the operator 5 being gripped is tightened, a pipe-like operation rod inserted through the spindle 3 12 is screw-fed by a spherical operation element 5 provided at the tip end 3a of the spindle, and one end 11a of the lever 11 is pressed to tilt the lever 11 within the key groove 4a. The horizontal rotary shaft 4 is fixed to the bearing hole 9 by the friction, and as a result, the support shaft 3 is fastened and fixed at an arbitrary inclination angle.

  In this way, the operator 5 can be loosened or tightened with one hand while holding the operator 5 at the tip 3a of the support shaft, and the support shaft 3 can be tilted to a desired angle with that hand. The angle can be adjusted without using it. Moreover, since the operator 5 of the support shaft tip 3a is always held with one hand while the angle is adjusted, the support shaft 3 is not accidentally tilted.

FIG. 4 shows another embodiment. 1 and 2 are denoted by the same reference numerals, and detailed description thereof is omitted.
In this example, the swing support part P is fixed to a horizontal rotating shaft 4 in which the support shaft 3 is inserted into the bearing hole 9 and is rotatably supported. A key groove 4a extending in the circumferential direction is formed, and a concave groove 4b is provided in the circumferential direction.
