Description

[Detailed explanation of the idea] This invention mainly relates to a tripod for a camera.

Conventional camera tripods do not have multiple pipes with legs that can be freely moved, and most of them are constructed so that they become a single rod shape even if they are extended or contracted. It gives off a delicate impression, and this feeling is especially strong when used by foreigners, many of whom are superior in physical strength to us Japanese.

The purpose of this invention is to provide a camera tripod that has a sturdy structure and can give a solid impression of stability.

This invention will be explained in detail below based on an embodiment shown in the drawings. Three legs 2 are rotatably attached to the lower part of a pedestal 1 of the tripod, and each of the legs 2 A pair of small pipe-shaped supports 5a, 5a, each having its upper and lower ends fixed by a connector 3.4, has a compound leg 5, and an insertion hole 4a provided in the connector 4 at the bottom of this compound leg 5. A pipe-shaped first single leg 8 that penetrates through the bearing 7, slides, and is housed between the struts 5a, 5a of the compound leg 5; The second single leg 9 and the precepts,
Each compound leg 5 is rotatably connected to the pedestal 1 by having the upper connector 3 pivoted on the support shaft 6, and the first single leg 8 is connected to the lower connector 4 by a screw fastener. The second single leg 9 is fixed to the lower connector 4 via a ring-shaped wedge body 11 by a fastening nut 10, and the second single leg 9 is also fixed to the ring by a tightening nut 12 screwed onto the lower part of the first single leg 8. shaped wedge 1
3 to the first single leg 8.

The upper end of the first single leg 8 is provided to prevent the first single leg 8 from falling out of the lower connector 4 and to allow it to swing back and forth about the insertion point into the lower connector 4 as a fulcrum. A flange 14 for preventing this is fixed, and this flange 14 is provided with protruding buffer members 15 on the upper and lower surfaces that contact the connectors 3 and 4 and on the sides that contact the sides of the columns 5a and 5a. ing.

Therefore, as shown in FIG. 1, in this tripod, the second single leg 9 is housed inside the first single leg 8, the first single leg 8 is housed between the supports 5a, 5a of the double leg 5, and each Tighten the nut 10,1
It can be carried in a fixed state at 2, opened and used in this state as needed, or it can be used by tightening nuts 10, 12.
Loosen and pull out the first single leg 8 or second single leg 9 according to the desired height, tighten the tightening nuts 10 and 12 again to secure each single leg 8 and 9, and then open and use. However,
The base of the leg 2 is made sturdy by the compound legs 5, so even if you handle it fairly roughly or place a fairly heavy camera on the pedestal 1, the leg 2 will remain stable.
There is no need to worry about it breaking or bending.

In addition, especially when the single legs 8 and 9 are all retracted, the leg part 2 is composed of three pillars, which makes it even more sturdy and gives it a solid appearance and a sense of stability. become able to.

Next, when the first single leg 8 expands and contracts, each support 5a of the compound leg 5,
At this time, since a flange 14 is provided at one end, the flange 14 locks the supports 5a, 5a, so that the first single leg 8 is connected to the lower connector. The upper and lower connectors 3 and 4 of this collar 14 and the support column 5
A buffer member 15 is provided in the portion that contacts the upper and lower connectors 3 and 5a, so that the collar 14 is connected to the upper and lower connectors 3 and 5a.
4 will not make a loud noise or damage the supports 5a, 5a.

Note that the shape and structure of the buffer member 15 are not limited to those in the embodiment, and may be configured integrally with the collar portion 14.

As explained in detail above, this invention allows the legs of a camera tripod to be constructed extremely robustly, and also
It gives the viewer a solid sense of stability, and
Even with this configuration, it is possible to achieve the effect that unnecessary noise is not generated during use, and the support that constitutes the compound leg is not damaged.
