In the example of FIG. 4, the arranging face is a wall.
As shown in these figures, the camera attaching device 10 has a first attaching base member 12 and a second attaching base member 14 as an entire construction. A camera attaching base is constructed by both the first attaching base member 12 and the second attaching base member 14. The first attaching base member 12 is attached to an arranging face 16. A camera 18 is attached to the second attaching base member 14. The first attaching base member 12 and the second attaching base member 14 form an internal wiring chamber 20 as an internal cavity. The second attaching base member 14 is attached to the first attaching base member 12 by a hinge portion 22 so as to be opened and closed. The construction of each portion will next be explained in detail.
The first attaching base member 12 is manufactured by aluminum and has a box shape. The first attaching base member 12 is constructed by a bottom plate 30 of a square shape and a side wall 32 arranged so as to surround the bottom plate 30. The bottom plate 30 functions as an attaching portion for attaching the first attaching base member 12 to the arranging face 16. Screws 36 are fastened to the arranging face 16 through holes 34 of the bottom plate 30 respectively. For example, a switch box 38 is buried within the arranging face 16, and the bottom plate 30 is fastened to the switch box 38.
The second attaching base member 14 is manufactured by aluminum, and is constructed by a cover portion 40 and an arm portion 42. The cover portion 40 has a square shape, and corresponds to the cover of a box shape structure of the first attaching base member 12. Namely, the cover portion 40 has a shape corresponding to the square shape made by the side wall 32 of the first attaching base member 12. Four sides of the cover portion 40 are connected to an end portion of the side wall 32 so that the internal wiring chamber 20 is formed.
The arm portion 42 has a shape of a sleeve type, and is projected from the center of the cover portion 40. A connecting portion 44 is arranged at the tip of the arm portion 42. The camera 18 is connected to the connecting portion 44. More specifically, a pan head 46 of the camera 18 is fitted to the connecting portion 44 of the arm portion 42, and both the cloud base 46 and the connecting portion 44 are fixed by screws.
The cover portion 40 is connected to the side wall 32 of the first attaching base member 12 by the hinge portion 22. Thus, the internal wiring chamber 20 can be opened and closed by rotating the cover portion 40 with the hinge portion 22 as a center. The hinge portion 22 is constructed by upper and lower convex portions 50, 52 arranged in end portions of the side wall 32, and a convex portion 54 arranged in an edge portion of the cover portion 40. The convex portion 54 of the cover portion 40 is inserted between the convex portions 50 and 52 of the side wall 32. A screw 56 then extends through the convex portions 50, 54, and is fastened to a screw hole of the convex portion 52. Thus, the screw 56 becomes a shaft and the convex portion 54 becomes a bearing so that a hinge structure is constructed.
As shown in the above figures, the hinge structure is arranged in each of two places on both sides of the first attaching base member 12 and the second attaching base member 14. Namely, the hinge structure is arranged in each of the two places with the internal wiring chamber 20 between. In this embodiment mode, one of the hinge structures in these two places is used. Namely, the screw 56 is assembled into one hinge structure, and the hinge function is obtained. The screw 56 is not assembled into the other hinge structure, and the other hinge structure is not used as a hinge. As described later, it is selected which hinge structure is used in accordance with a camera arranging place.
Further, four holes 60 are arranged in the cover portion 40 so as to surround the arm portion 42. Four bosses 62 are projected in the bottom plate 30 of the first attaching base member 12 correspondingly to the four holes 60. Screw holes are arranged in the bosses 62 respectively. Screws 64 are fastened to the bosses 62 through the holes 60 respectively. Thus, the second attaching base member 14 is fixed to the first attaching base member 12.
An edge wall portion 66 is arranged so as to be extended along the edge of the cover portion 40. An edge wall portion 68 is also arranged in the first attaching base member 12 along the end portion of the side wall 32. The edge wall portion 66 of the cover portion 40 is fitted to the outside of the edge wall portion 68 of the side wall 32. Thus, the invasion of dust, etc. into the internal wiring chamber 20 is prevented.
Further, a clamp 70 is attached to the rear side of the cover portion 40. The clamp 70 is arranged in an inlet portion to the internal cavity of the arm portion 42. A cable 72 of the camera side is caught in the clamp 70. The cable 72 is connected to the camera 18 through the interior of the arm portion 42.
The cable 72 of the camera side is connected to a cable 74 of the arranging face side within the internal wiring chamber 20. The cable 74 of the arranging face side is extended within the arranging face 16 through a hole 76 arranged in the bottom plate 30. The cable 74 is extended to the switch box 38 buried within the arranging face 16.
A decorative cover 80 manufactured by resin is attached to the front side of the cover portion 40. The decorative cover 80 is fixed to screw holes 84 of the cover portion 40 by screws 82.
The construction of the camera attaching device 10 of this embodiment mode has been explained as mentioned above. Next, an example of a preferable procedure of a camera attaching construction work using the camera attaching device 10 will be explained.

Here, the screw 36 is inserted into the hole 34 of the bottom plate 30, and is fastened to the switch box 38 buried within the arranging face 16. At this time, the cable 74 of the arranging face side is also pulled out into the box of the first attaching base member 12 through the hole of the bottom plate 30. The cable 74 is extended from the switch box 38.
Next, the hinge structure is formed by the second attaching base member 14 and the first attaching base member 12. The cover portion 40 of the second attaching base member 14 is set to approach the side wall 32 of the first attaching base member 12. The convex portion 54 of the edge of the cover portion 40 is then inserted between the two convex portions 50 and 52 of the side wall 32. The screw 56 is then inserted into the holes of the convex portions 50, 54, and is fastened to the screw hole of the convex portion 52. Thus, the hinge structure is obtained.
Next, the camera 18 is attached to the tip of the arm portion 42 of the second attaching base member 14. At this time, the cable 72 of the camera side is inserted into the arm portion 42. The cable 72 is inserted into the arm portion 42 and appears on the rear side of the cover portion 40 and is caught in the clamp 70. The clamp 70 is attached to the rear side of the cover portion 40 in advance. The cable 72 is then connected to the cable 74 of the arranging face side.
Next, the cover portion 40 is closed by using the hinge structure. The edge wall portion 66 of the cover portion 40 is fitted into the outside of the edge wall portion 68 of the side wall 32 of the first attaching base member 12. The screws 64 are then inserted into the holes 60 of the cover portion 40 and are fastened to the bosses 62 of the first attaching base member 12. Thus, the second attaching base member 14 is fixed to the first attaching base member 12.
Next, the decorative cover 80 is attached to the cover portion 40 by the screws 82. Thus, the camera attaching construction work is made.
FIG. 5 shows a selecting example of the hinge structure according to the camera arranging place. FIG. 5 is a schematic view of a state of the camera attaching device 10 seen from above.

Namely, a screw as a shaft is attached to the hinge 92 of the right-hand side. No screw is attached to the hinge 90 of the left-hand side. Thus, the second attaching base member 14 is opened and an internal line connecting work can be made without an interference of the arm portion 42 with the wall 94.
In FIG. 5B, the camera arranging place is located near the wall 96 of the right-hand side. In this case, a screw as a shaft is attached to the hinge 90 of the left-hand side. Thus, the hinge 90 of the left-hand side is used. Accordingly, in this case, the second attaching base member 14 is also opened and the internal line connecting work can be also made without an interference of the arm portion 42 with the wall 96.
As explained above, the camera attaching device 10 of this embodiment mode has the first attaching base member and the second attaching base member, and the internal wiring chamber is constructed by both the first attaching base member and the second attaching base member, and both the first attaching base member and the second attaching base member are connected by the hinge. In a state in which the first attaching base member 12 is fixed to the camera arranging place and the second attaching base member 14 is attached to the first attaching base member 12, the second attaching base member is opened by utilizing the hinge portion 22 and the line connection processing of the internal wiring chamber 20 can be performed. Accordingly, the attaching construction work can be easily made. Further, since the internal wiring chamber 20 is arranged, camera wiring can be avoided from exposure and the external appearance image can be improved.
Further, in accordance with the camera attaching device 10 of this embodiment mode, the first attaching base member 12 and the second attaching base member 14 have plural hinge connecting structures so as to open and close the second attaching base member in plural directions. Thus, the camera can be arranged in corner portions of the plural directions, and the degree of freedom of the camera arranging place can be increased.
