Embodiment 2
This embodiment is shown in FIG. 6, and the attachment target part of the camera fixture 1 in the first embodiment is changed.

  That is, in the first embodiment, the case where the small camera 3 is supported and fixed by the ski stock 2 using the camera fixture 1 has been described, but in this embodiment, as shown in FIG. A camera fixture 1 is attached and fixed to a handrail 51a of a balcony 51 in a hut 50 such as a lodge or a bungalow, and the small camera 3 is supported and fixed to a male screw portion 6 of the camera fixture 1.

In this case, since there is no existing screw hole as in the first embodiment, a fixing hole main body 5 of the camera fixing tool 1 is inserted and supported after a pilot hole has been previously drilled in the attachment target portion of the handrail 51a. As shown in FIG. 4A, the rotary tool 30 is rotationally engaged with the tool gripping portion 12c of the flange portion 12, and the camera fixing tool 1 is fastened and fixed to the handrail 51a by performing a tightening rotation operation.

Subsequently, the tripod female screw portion 11 of the camera main body bottom portion 10a of the small camera 3 is relatively rotated and screwed into the male screw portion 6 of the fixture main body 5. Since the camera fixture 1 is fixed to the handrail 51a and cannot be rotated, the small camera 3 is rotated with respect to the male screw portion 6 of the camera fixture 1 in the fixed state. .

In such a structure, the required operation rotational speed of the tripod female screw portion 11 of the small camera 3 with respect to the male screw portion 6 of the fixture main body 5 tends to fluctuate unsteadily. It is also conceivable that the shooting direction when the support is fixed does not face the desired direction.

In the present embodiment, in consideration of such a situation, an elastic washer 52 made of elastic rubber or the like is interposed between the male screw portion 6 and the bottom portion 10a of the camera body 10 (FIG. 6B). ) (Refer to the two-dot chain line), the small camera 3 can be supported and fixed in a desired photographing direction without damaging the bottom 10a of the camera body 10.

Moreover, in the usage form of the camera fixture 1 as in this embodiment, the camera fixture 1 is permanently attached to the handrail 51a of the balcony 51 instead of being temporarily or temporarily attached and fixed.

  That is, in this embodiment, as shown in FIG. 7 (a), the camera fixture 1 is attached and fixed to the open / close lid 61 of a foamed cooler box 60 used in outdoor activities such as fishing, and this camera is fixed. The small camera 3 is supported and fixed to the male screw portion 6 of the tool 1.

Also in this case, there is no existing screw hole as in the second embodiment, but the fixing target body 5 of the camera fixing tool 1 is not formed in advance without making a pilot hole because the attachment target site is made of foamed polystyrene and a soft material. 4A, with the rotary tool 30 rotated and engaged with the tool gripping portion 12c of the flange portion 12 and tightening and rotating as shown in FIG. 1 can be easily clamped and fixed to the open / close lid 61 of the cooler box 60.

In such a structure, as in the case of the second embodiment, the required operation rotational speed of the tripod female screw portion 11 of the small camera 3 with respect to the male screw portion 6 of the fixture main body 5 tends to fluctuate unstably. However, since the attachment target part is made of foamed polystyrene and a soft material, the degree of freedom in the photographing direction when the small camera 3 is supported and fixed is greater than in the second embodiment.

In addition, since the cooler box 60 can be moved by hand, it is possible to take a free photographing posture and photographing direction by placing the cooler box 60 at an arbitrary position.
Other configurations and operations are the same as those of the first embodiment.

  In addition, Embodiment 1-3 mentioned above shows the suitable embodiment of this invention to the last, This invention is not limited to this, A various design change is possible within the range.

  For example, in the first embodiment, the case where the camera fixture 1 is applied to the top 2 a of the ski stock 2 and the small camera 3 is supported and fixed by the ski stock 2 is shown. The same applies to the top of the tracking pole with the structure.

  Further, the specific shape of the tool gripping portion 12c in the flange portion 12 of the illustrated embodiment may be a shape like a hexagon bolt head.
