Description

[Detailed Description of the Invention] Technical Field The present invention relates to a belt connecting device that doubles as a pedestal and is attached to an optical device using a screw hole for attaching a tripod.

Prior Art Generally, in optical equipment such as video cameras,
There are two connecting parts that connect the hanging belt for carrying the device to the main body of the device.However, since a large force is applied to the connecting part of the hanging belt, the connecting part of the main body is attached to the connecting part of the main body. It was necessary to strengthen the device only by reinforcing it, which was an obstacle to simplifying and reducing the weight of the device itself.

Because of these disadvantages, a connecting device for a suspension belt, as shown in FIG. 1, has been provided, which is attached to an optical device using a screw hole for attaching a tripod. The screw head 15, which has a screw hole 15A for mounting a tripod in the center, the auxiliary part 16, and the screw part 17 are each formed integrally, and the screw head 15 and the auxiliary part 1
A ring holder 18 is provided between the ring holder 6 and the ring holder 18 and is rotatably provided with a ring 19 for hanging a hook of a hanging belt or the like. One end of the hanging belt is connected by fixing this connecting device to a screw hole for attaching a tripod of the device using the threaded portion 17. This allows one of the connecting parts of the hanging belt to be omitted.

However, in the case of the above-mentioned coupling device, the tripod mounting screw hole is usually provided on the bottom of the device, so when the coupling device is attached, the coupling device gets in the way and makes it difficult to stand the device in a stable state. There was a drawback that I couldn't keep it in place. In addition, as shown in the figure, a screw head 15, an auxiliary part 16 and a ring holder 18 are provided.
Because it has a triple-layered structure, it is thick, and when attached to a device, it protrudes to the outside and is very obstructive. In addition, since the screw head 15, the auxiliary part 16, the threaded part 17, the ring holding part 18, and the ring 19 are made of metal and are assembled into the above-described structure, the assembly work is troublesome.

Purpose of the invention The present invention was made in view of the problems of the conventional art as described above, and its purpose is to provide a connection device for a suspension belt that is attached to an optical device using a screw hole for mounting a tripod. The purpose of the present invention is to propose a belt connecting device that also has a pedestal on which the main body can be stably placed.

Another object of the present invention is to propose a belt connecting device that is not obstructive due to its small overall thickness and is extremely easy to assemble.

It is inserted into the grooves 1D-1 and 1D-2 of C-2, and is clamped and fixed by fixing members 4 and 5 from above. Then, the cover 6 is folded back at the connecting pieces 6B, 6C and placed over the base 1.

As can be seen from the above description, in the belt connecting device according to this embodiment, the hanging tool 2 is connected to the base 1.
The set screw 3 and the cover 6 are fixed using only the fixing members 4 and 5, and can be assembled extremely easily. In addition, since the set screw 3 is structured to hold the hanging tool 2 inside the base 1,
The thickness can be reduced, and even when attached to the device body, it does not protrude to the outside so much.

The connecting device assembled as described above is attached to a tripod attaching screw hole provided on the bottom surface 10A of the optical device main body 10 using the setscrew 3, as shown in FIG. Then, one end of the hanging belt is connected to the hanging tool 2. At this time, since the base 1 of the coupling device has a horizontally long shape as described above, the optical device can be stably placed while the belt coupling device is attached. In other words, it can be used as a pedestal. Furthermore, when used as a pedestal, the cover 6 is made of a non-slip material such as rubber, so that the main body of the device can be more stably placed on a table or the like. Furthermore, when the belt connecting device is attached to the main body of the device and suspended by the belt as described above, it is conceivable that the set screw 3 may loosen due to vibrations applied to the connecting device. Now, the protrusion 6E of the cover 6
is press-fitted into the screw hole 3E of the screw head 3A, so
Vibrations applied to the set screw 3 are absorbed and loosening is effectively prevented. Further, the cover 6 prevents the table head from being damaged at all.

As shown in FIGS. 8B and 8C, the cover 6 is formed in an inclined manner so that its thickness gradually decreases. Due to this structure, when the main body 10 of the device is placed as shown in FIG. 10, the main body 10 is tilted by the thickness of the belt connecting device, but the bottom surface of the cover 6 is in close contact with the surface on which the main body 10 of the device is placed. This results in more stability. In this embodiment, the cover 6 is provided with a slope and the cover can be opened and closed freely since forming a slope on the base 1 would hinder the attachment of the tripod.

Further, the base 1, the hanging tool 2, and the set screw 3 of the above embodiment are made of materials such as metal or plastic.

Further, when the cover 6 is opened, a tripod screw hole 3E is provided in the screw head 3A, so that a tripod can be used. At that time, the cover 6 opens more than 180 degrees, so it does not get in the way when using a tripod. Furthermore, the front of the tripod screw of the video camera tripod is JIS
Although there is a protrusion according to the standard, the stepped portion 1A of the base is provided with a notch 1A-1 for receiving the protrusion.

Effects As described above, according to the present invention, a hanging belt can be connected using the screw hole for mounting an optical device on a tripod, and the optical device can also be used as a pedestal on which the optical device can be stably placed. is possible. Also, since the overall thickness is small, it does not get in the way. Furthermore, since the structure is simple, just assemble the parts, assembly is extremely easy.

Further, a tripod can be attached even when this belt connecting device is attached to the main body of the device.

Furthermore, since the hanger is rotatable, the load on the belt can be reduced and the life of the belt can be extended.
