TECHNICAL FIELD The present invention relates to an adapter for mounting a tripod of a camera.

[0002]

2. Description of the Related Art A camera generally has a screw hole for mounting a tripod (head) on the bottom side. In the case of so-called horizontal shooting in which the camera bottom having the screw holes is directed downward, the stability by supporting the tripod is high. On the other hand, in the case of vertical shooting in which the camera is set to be orthogonal to the horizontal shooting, in order to support the camera with a tripod, the camera platform is tilted about 90 degrees in the vertical direction or an L-shaped Or a mold adapter. In such a support structure, when the camera is taken in the vertical position, the camera is connected to the camera platform or the L-shaped adapter by the fixing screw whose axis is oriented in the horizontal direction, so that the stability is poor. For example, the fixing screw is loosened. In such a case, the camera may be tilted in the rotation direction. If the camera is heavy, the load on the fixing screw becomes excessive. The conventional L-shaped adapter has a horizontal support arm along the bottom side of the camera and a vertical support arm along the side of the camera, and is screwed into the screw hole on the camera side with the horizontal support arm. It has a fixing screw.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a tripod mounting adapter which does not impair the stability of a camera even in a so-called vertical shooting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A tripod mounting adapter 10 according to one embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a tripod mounting adapter 10 as viewed from the front, and FIGS. 2 to 5 show the tripod mounting adapter 10 as viewed from up, down, left and right. In the following description,
The front-back direction of the tripod-mounting adapter 10 corresponds to the front-rear direction of the camera when attached to the camera, and the up-down direction corresponds to the up-down direction of the camera when the camera is held in the horizontal position.

The tripod mounting adapter 10 viewed from the front is
It has an L-shape including a lateral position support arm 11 and a vertical position support arm 12 extending substantially perpendicular to the lateral position support arm 11. Although details will be described later, when the tripod mounting adapter 10 is attached to the camera, the horizontal position support arm 11 is located along the bottom surface of the camera, and the vertical position support arm 12 is located along the side surface of the camera. On the upper surface side (the surface facing the camera) of the lateral position support arm 11, a mount plate 13 formed in a planar shape for mounting the camera is provided. A male screw portion 14a of the camera fixing screw 14 protrudes from the mount plate 13, and an operation knob 14b for rotating the male screw portion 14a is supported on the lower surface of the lateral position support arm 11. The male screw portion 14a is screwed into a tripod mounting screw hole (female screw) provided in the camera to fix the tripod mounting adapter 10.

A knob housing hole 15 is formed in the lower surface of the lateral position support arm 11. The operation knob 14b is rotatably supported in the knob storage hole 15. A mounting plate 16 for mounting the lateral position support arm 11 on a tripod (head) is further provided on the lower surface side of the lateral position support arm 11. An opening corresponding to the knob storage hole 15 is formed in the mount plate 16 so that the operation knob 14b is exposed even when the knob storage hole 15 is attached. However, since the thickness of the operation knob 14b is smaller than the sum of the depth of the knob storage hole 15 and the thickness of the mount plate 16, the operation knob 14b does not protrude below the mounting surface of the knob storage hole 15 (see FIG. 4). ), The operation knob 14b does not interfere with the tripod head when a tripod (head) is attached to the lateral position support arm 11.
Behind the operation knob 14b, a tripod (head) through the mount plate 16 to a certain depth of the lateral support arm 11
Mounting screw hole 17 for screwing the fixing screw on the side
Are formed.

A bracket 20 extends from the vertical support arm 12 toward the side of the camera (to the left in FIG. 1). A part of the bracket 20 is cut out, and a support member 21 (camera body support part) is provided in the cutout part.
Has been fixed. The support member 21 is formed with a keyhole 22 having an opening facing in the front-rear direction. This keyhole 2
2 has a large-diameter detachable end 23 and a small-diameter engagement end 24.
As will be described in detail later, in the tripod mounting adapter 10, the projection on the camera side is engaged with the
The camera can be held more stably than a conventional L-shaped adapter.

In the vertical position support arm 12, the bracket 2
A mounting plate 25 for mounting the vertical position support arm 12 on a tripod (head) is fixed to the surface on the opposite side of the mounting plate 25. A tripod mounting screw hole 26 is formed to penetrate and screw a fixing screw on the tripod (head) side. That is, the tripod mounting adapter 10 can be selectively fixed to the tripod at two positions, the horizontal position support arm 11 (mount plate 16) and the vertical position support arm 12 (mount plate 25).

A state in which the camera 40 is supported by the tripod mounting adapter 10 having the above configuration will be described with reference to FIGS. 6 and 9, the pentaprism section 40P shown in FIG. 7 is omitted, but the camera body 41 is common.

The camera 40 has, on the bottom side of the camera body 41, a tripod mounting screw hole 42 into which the male screw portion 14a of the camera fixing screw 14 can be screwed. Further, a pair of strap attaching / detaching projections 43 and 44 are formed integrally with the camera body 41 on the upper right and lower right portions of the front of the camera body 41. In the present embodiment, the upper strap attaching / detaching protrusion 43 (supported portion) is the tripod mounting adapter 1.
Supported by 0. As shown in FIG. 10, the strap attaching / detaching projection 43 has a large-diameter head 43a, a small-diameter neck 43b, and a base 43c.
2 corresponds to the diameter of the detachable end 23, and the neck 43b is
Corresponding to the diameter. The base 43c has a larger diameter than the head 43a.

When attaching the tripod adapter 10 to the camera 40, first, the strap attaching / detaching projection 43 is inserted into the attaching / detaching end 23 of the keyhole 22. Since the diameter of the detachable end 23 corresponds to the head 43a, the support member 21
The head 43a and the neck 43b can be inserted until they abut. In this inserted state, the strap attaching / detaching projection 4
The third neck 43b is fitted in the keyhole 22 (the detachable end 23). Subsequently, the neck portion 43b of the strap attaching / detaching protrusion 43
The support member 21 (the tripod mounting adapter 10) is slid so that is moved into the engagement end 24. Then, since the head 43a has a larger diameter than the engagement end 24, the head 4a
The support member 21 is prevented from coming off by 3a. When the tripod mounting adapter 10 is slid to this retaining position, the mount plate 13 on the side of the lateral position support arm 11 comes into contact with the bottom surface of the camera body 41. Here, the position of the camera fixing screw 14 on the tripod mounting adapter 10 and the position of the tripod mounting screw hole 42 on the camera 40 are aligned, and the operation knob 14b is rotated in the tightening direction.
When the male screw portion 14a is screwed into the tripod mounting screw hole 42, the tripod mounting adapter 10 is completely fixed to the camera 40 (see FIGS. 6 to 9). In this fixed state, the support member 21 is maintained in a state of being prevented from being detached from the strap attaching / detaching projection 43, and the tripod mounting adapter 10 is connected to the lateral support arm 11 (camera fixing screw 1) with respect to the camera bottom surface.
4) and the support member 2 engaged with the strap attaching / detaching projection 43
The camera 40 will be supported at two points (1).

When performing the horizontal position photographing, a tripod head is mounted on the side of the horizontal position support arm 11 as shown by a two-dot chain line 50L in FIG. At this time, by fixing a fixing screw (not shown) provided on the camera platform 50L to the tripod mounting screw hole 17, the camera platform 50L abuts on the mount plate 16 and is fixed. On the other hand, when performing the vertical position shooting, the tripod mounting adapter 10 and the camera 40 of FIG. 6 are rotated by 90 degrees, and the tripod head is mounted on the vertical position supporting arm 12 as shown by a two-dot chain line 50H in FIG. Attach. At this time, the method of fixing the tripod is the same as that for shooting in the horizontal position.
6, the camera platform 50 </ b> H is fixed to the mount plate 25.

As described above, in the conventional camera support structure, the camera is unstable and tends to tilt, especially in vertical shooting. For example, when trying to support the camera 40 in the vertical position without using an adapter such as the tripod mounting adapter 10, first, the camera platform is set to the 50L angle position in FIG. Directly into the tripod mounting screw hole 42 of FIG. Then, the camera platform is tilted by about 90 degrees by an angle adjustment mechanism (not shown) provided on the camera platform side. Such a supporting state is unstable, and if the fixing screw is loosened even slightly, the camera 4 is rotated around the fixing screw.
0 easily falls back and forth, and the load on the fixing screw increases. Further, if the support strength of the angle adjustment mechanism on the camera platform side is weak, the camera 40 cannot be held in the vertical position, so that a usable tripod is also limited. If an L-shaped adapter having a vertical mount is used, it is not necessary to tilt the camera head at least, but the conventional L-shaped adapter only supports and fixes the camera to the camera by screwing it to the bottom of the camera. As a result, the camera may fall back and forth, and the load on the fixing screw may be excessive.

On the other hand, the tripod mounting adapter 1 of the present embodiment
0, the camera 40 is not only supported on the side of the lateral position support arm 11 by screwing the camera fixing screw 14 and the tripod mounting screw hole 42, but also by the engagement relationship between the keyhole 22 of the support member 21 and the strap attaching / detaching projection 43. , The camera 40 does not fall as described above, and the camera fixing screw 1
No excessive load is applied to 4 as well. Specifically, the camera 4
The weight of 0 is not only the camera fixing screw 14 but also the supporting member 2.
The load is not concentrated on the camera fixing screw 14 since the light is transmitted to the tripod even through 1. Also, even if a force acts to tilt the camera 40 back and forth around the camera fixing screw 14,
Since the small-diameter neck 43a is engaged with the small-diameter engaging end 24, the strap attaching / detaching projection 43 has a head 43a and a base 43c.
Regulates its movement. Therefore, even if the camera fixing screw 14 is slightly loosened, the camera 40 does not fall back and forth, and stable vertical shooting is guaranteed.

When removing the tripod mounting adapter 10 from the camera 40, the operation knob 14b is rotated in the loosening direction to release the screwing of the male screw portion 14a and the tripod mounting screw hole 42.
The tripod mounting adapter 10 may be slid so that the strap attaching / detaching projection 43 is located inside the attaching / detaching end 23. As a result, it is possible to release the strap attaching / detaching protrusion 43 from the keyhole portion 22 and release the engagement between the two.

As is apparent from the above description, the tripod-mounting adapter 10 includes the horizontal support arm 11 and the vertical support arm 1.
Since each of 2 was configured to support the camera,
Stable camera support is possible even in vertical shooting. Also, when used in horizontal position shooting, improvement in stability can be expected.

FIG. 11 shows a different embodiment. The camera 140 shown in the figure is provided with a strap attachment / detachment projection 143 similar to the strap attachment / detachment projection 43 on the side rather than the front of the camera body 141.
A support member 121 extends from the vertical position support arm 12 so as to engage with the strap attaching / detaching protrusion 143. Although not shown, the support member 121 is formed with a keyhole having a large-diameter detachable end and a small-diameter engagement end similarly to the keyhole 22 described above, and the head of the strap detachable projection 143 is formed in this keyhole. And the neck is inserted and slid to the retaining position.
Contacts the bottom surface of the camera body 141. Then, by screwing the camera fixing screw 14 into the tripod mounting screw hole 42 in this retaining state, the tripod mounting adapter 110 can be mounted on the camera 140. As is clear from this embodiment, the position of the supported portion on the camera body side in the present invention can be variously changed. For example, the strap attaching / detaching protrusion may be located on the upper surface side or the rear surface side of the camera body.

Further, in the above embodiment, the supported portion on the camera body side is a hook-shaped strap attaching / detaching protrusion having a head and a neck, and the keyhole portion is formed on the camera body supporting portion on the adapter side. The shapes of the support and the camera body support are not limited to the embodiments. Although not shown, for example, when a hole for inserting a strap is formed in the camera body, this strap insertion hole is used as a supported portion on the camera body side, and the adapter is connected to the vertical support arm of the adapter in relation to the strap insertion hole. Support projections that match may be formed. Further, the supported portion on the camera side may be provided for purposes other than attaching and detaching the strap.

[0021]

As is clear from the above, according to the present invention, it is possible to obtain a tripod mounting adapter in which the stability of the camera is not impaired even in vertical shooting.
