  However, the tripod is relatively large, and when the camera is attached to the tripod, the overall size becomes considerably large. On the other hand, it is conceivable to attach the camera to a simple table stand using a unique connector, but the camera itself does not have a tilt mechanism, and if the tilt mechanism is to be realized, the tripod tilt mechanism is used. You must use it.

  In view of the above circumstances, the present invention can easily attach the camera to the stand by using a connecting member for connecting the camera and the tripod, and further properly determines the camera posture on the stand. It is another object of the present invention to provide a camera stand structure that can tilt the camera on the stand.

  In order to solve the above problems, the camera stand structure of the present invention uses a connecting member having a tripod screw hole for connecting the camera and a tripod, and the connecting member is used as a groove portion of the intermediate support member. The intermediate support member can be slid and fitted, and the intermediate support member is attached to a stand.

  If it is said structure, a camera can be easily mounted | worn to a stand using the connection member for connecting a camera and a tripod.

  In the camera stand structure described above, the intermediate support member is formed with an elastically supported piece, and the piece is formed with a substantially hemispherical convex portion, and the tripod screw hole of the connecting member The basic posture of the camera may be determined when the convex portion is locked. According to this, the camera posture on the stand can be properly determined.

  In the camera stand structure configured as described above, the portion of the connecting member that is slidably fitted into the dovetail groove portion has an arc shape, the dovetail groove portion also has an arc shape, and the connecting member is disposed in the dovetail groove portion. The camera may be configured to perform a tilting operation by sliding the screen. According to this, the camera can be tilted on the stand without using a tripod.

  In these camera stand structures, it is preferable that a stopper for limiting the range of sliding movement of the connecting member is formed on the side of the intermediate support member opposite to the connecting member entrance. In addition, a recess may be formed in the stand, and the intermediate support member may be inserted into the recess, and the inner surface of the recess may serve as a stopper that limits the range of sliding movement of the connecting member. The concave portion has a circular shape, and the intermediate support member also has a circular shape. Further, a substantially rectangular insertion hole is formed in the concave portion, and the intermediate support member has a substantially rectangular locking plate portion. The intermediate support member is inserted into the recess, and the substantially rectangular engagement plate portion is rotated with the substantially rectangular insertion hole inserted into the substantially rectangular engagement plate portion. It is good also as a structure which a stop plate part is located in the back surface side of the said recessed part, and the said intermediate | middle support member is fixed to the said stand.

  According to the present invention, the camera can be easily attached to the stand using the connecting member for connecting the camera and the tripod. Since the basic posture of the camera is determined when the convex portion of the intermediate support member is locked in the tripod screw hole formed in the connecting member, the camera posture on the stand can be appropriately determined. Since the camera tilts by sliding the connecting member in the groove, it is possible to eliminate the need to purchase a tripod for tilting. Of course, for a user who already has a tripod, the camera can be attached to the tripod using the connecting member.

  A camera stand structure according to an embodiment of the present invention will be described below with reference to FIGS.

  FIG. 1 is an exploded perspective view showing a connecting bracket 1, an intermediate support member 2, and a stand 3 constituting a camera stand structure.

  A total of four screw insertion holes 1a are formed on both sides (flange portions) of the connection fitting 1, and the camera 5 (see FIG. 2, etc.) is connected to the connection fitting by screws (not shown) inserted through the screw insertion holes 1a. 1 is fixed. And the hole 1b for tripod screws is formed in the center part (concave part) of the connection metal fitting 1. As shown in FIG. A screw is formed on the top of a tripod (not shown), and the camera 5 can be fixed to the tripod by passing this screw through the hole 1b for the tripod screw. In addition, although the center part (recessed part) in a normal connection metal fitting has a flat shape, the center part (recessed part) of the said connection metal fitting 1 has circular arc shape (it protrudes in the downward side toward the center in FIG. Have. The central portion (concave portion) is larger in the lateral direction than the both sides (flange portions). That is, the central portion (concave portion) has a portion (hereinafter referred to as a protruding portion 1c) that protrudes from both sides (flange portions).

  The intermediate support member 2 includes a substantially disc-shaped main body portion 21 and a rectangular locking plate-like portion 22 existing on the bottom surface side of the main body portion 21. In the main body 21, there is a dovetail groove 21 a formed from the front side to the back side in FIG. 1. The interval between the lip portions in the dovetail groove 21a is substantially equal to the width of both sides (flange portions) of the connection fitting 1, and the interval between the inner walls of the dovetail groove 21a is the width of the central portion (recess) of the connection fitting 1. It is almost coincident. The length of the dovetail groove 21a is longer than the length of the central portion (concave portion) of the connecting fitting 1 (the length in the direction orthogonal to the width).

  The front side portion of the dovetail groove 21a becomes the entrance of the connecting fitting 1. The connecting fitting 1 is inserted into the dovetail groove 21a from this entrance, and the connecting fitting 1 is slid to fit the protruding portion 1c of the connecting fitting 1 into the dovetail groove 21a (see FIG. 2). Since mounting can be performed by fitting by such a slide, mounting effort is not required and removal is easy. A stopper 21d for limiting the range of sliding movement of the connecting metal fitting 1 is formed at a location opposite to the entrance.

  As shown also in FIG. 3, the dovetail groove 21 a has an arc corresponding to the arc shape of the central portion (concave portion) of the connection fitting 1. This circular arc is centered on one point on the lens optical axis of the camera 5 and passes through the groove 21a. By sliding the connecting metal fitting 1 in the dovetail groove 21a, the connecting metal fitting 1 moves along an arcuate track having the arc shape. As a result, as shown in FIGS. 4A and 4B, the camera 5 connected to the connection fitting 1 performs a tilt operation.

  A central portion of the main body 21 is formed with a piece 21b that is connected to the main body 21 only on one side (elastically supported). A substantially hemispherical convex portion 21c is formed on the upper surface of the piece 21b. Is formed. The convex portion 21c is fitted from below into a hole 1b for a tripod screw formed in the connection fitting 1 by the mounting by the slide. The basic posture of the camera 5 is determined in this fitted (locked) state. In this embodiment, the basic posture of the camera 5 is such that the lens optical axis of the camera 5 is horizontal (the optical axis and the bottom of the stand are parallel). Since the click feeling is obtained when the convex portion 21c is locked in the tripod screw hole 1b, the user can easily recognize that the camera 5 is in the basic posture. In addition, since the basic posture of the camera 5 is maintained using the tripod screw hole 1b originally present in the connection fitting 1, the structure can be simplified.

  The locking plate-like portion 22 of the intermediate support member 2 is formed long from the front side to the back side in FIG. A locking recess 22 a is formed at the front side end and the back side end of the locking plate-like portion 22.

  A recess 3 a is formed in the stand 3. The recess 3 a has a circular shape with a size corresponding to the main body 21 of the intermediate support member 2. In a state where the main body portion 21 of the intermediate support member 2 is inserted into the recess 3a, the inner surface of the recess 3a serves as a stopper that limits the range of sliding movement of the connecting metal fitting 1. A rectangular insertion hole 3b is formed in the bottom plate portion of the recess 3a. This rectangular insertion hole 3b is long in the horizontal direction (left-right direction). By turning the intermediate support member 2 in a state where the main body portion 21 of the intermediate support member 2 is inserted into the concave portion 3a and the locking plate-like portion 22 is inserted into the rectangular insertion hole 3b, the locking plate-like portion 22 is formed. The intermediate support member 2 is fixed to the stand 3 on the back side of the recess 3a. Moreover, the convex part 3c * 3c which protrudes below is formed in the back surface side of the recessed part 3a, and the latching recessed part 22a of the latching plate-shaped part 22 engages with the convex part 3c * 3c. When removing the camera 5 from the stand 3, the intermediate support member 2 may be rotated in the reverse direction.

  A transparent dome 5a is provided at the front portion of the camera 5, and the lens portion of the camera 5 is positioned on the transparent dome 5a. In addition, an insertion slot for the wireless LAN card 6 is formed at the rear of the camera 5.
