Description

[Detailed description of the invention] The tripod of this invention is easy to attach and detach between the main body and the leg rod.
In addition, it is convenient to use because it allows two types of mounting angles.

It consists of a leg rod with screws 20 and 21 screwed together, respectively.

Telescope tripods are used by attaching short metal legs or long wooden legs to the telescope mount depending on the situation, but to replace them, you need to tighten the wing nut that tightens the shaft bolt that connects the two legs. The drawback is that you have to turn the bolt many times to remove it, then remove the bolt, then replace the leg and match the holes, then insert the bolt and turn the wing nut many times to tighten it, which is very time-consuming. be.

The tripod of this invention eliminates the above-mentioned drawbacks and also has other effects. Next, to explain the usage condition, FIG. Engagement recess 9 with a small height, that is, a small distance 9 from the lower surface 10'
The engaging recess 9 provided at the position L is shown engaged, and the leg rod 13 opens at a large angle α with respect to the axis 1a of the mount 1, so that the tripod can be used stably.

Figure 4 shows a thick washer 1 attached to the lower edge of the front plate of the leg rod attachment part 2.
0, the engagement recess 8 provided at a position having a large distance 8L from the lower surface 10' is engaged. Since it can only be opened at a small angle β, it can be used as a high tripod.

In other words, as shown in FIG. 4, the leg rod 13 cannot open any further because the engagement recess 8 is provided after a long distance 8L, but the engagement recess 9 extends further downward than the engagement recess 8. Therefore, the leg rods 13 can be further expanded as shown in FIG.

Note that the aforementioned concave portion extending downward means that the distance 9L from the lower surface 10' to the side surface 9a is smaller than the distance 8L.

Next, when replacing the leg rod 13 with the main leg, use the wing nut 19,
After slightly loosening the bolts 20 and 21, the bolt 16 is pulled out from the notch 2'' by pulling the leg rod 13 downward, and the leg rod 13 is separated from the leg rod mounting portion 2.

Then, the U-shaped part at the top of the main leg is fitted into the leg-rod attachment part 2, and the attachment bolt is inserted into the notch 2'' of the leg-rod attachment part 2, and the wing nut is tightened to connect them.

In the tripod of this invention, the leg rod attachment part of the telescope mount has a pair of side plates and a front plate that interconnects the front edges of both side plates, with the lower surface open, and deep cuts are made in both side plates. Since the recess is formed perpendicularly from the lower edge, to attach the leg rod to the mounting base, all you need to do is insert the mounting bolt at the top of the leg rod into the notch and tighten it by slightly turning the nut.To remove it, do the reverse operation. The replacement operation with the main leg can be performed easily and quickly.

Then, fit a thick washer into the bolt that connects the leg rod and the U-shaped lower body, and the thick washer forms two types of engagement recesses, and the distance from the bottom surface of the thick washer to the engagement side of each engagement recess is determined. Since it is formed to be large and small, if the leg rod is installed so that the engagement recess with a large distance engages with the mounting part, the leg rod will only open at a small angle with respect to the axis of the mount, so it can be used as a high tripod. Furthermore, if the leg rods are installed so that the engagement recesses having the short distance are engaged, the leg rods can be used stably because they open at a large angle.

A square hole was made in the center plate of the U-shaped body, and the square hole on the bottom of the thick nut was fitted into this hole, making it an artist! It is possible to assemble the engaging recessed portion of the surface having the larger distance or the engaging recessed portion having the smaller distance in a predetermined direction.
