DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an example of a shoulder belt according to the present invention applied to the above-mentioned video camera.

In FIG. 1, 11 indicates the shoulder belt of this example as a whole. Shoulder belt 11 in this example
The main body is made of a braided fiber, leather, or other flexible member. Then, by engaging one end and the other end of the belt 11 with the hooks 2 and 3 of the video camera body 1,
It has first and second attaching portions 12 and 13 such as hook engaging portions for attaching the shoulder belt 11.
In the illustrated example, when the belt 11 is hung on the shoulder to carry the video camera 1, a pad 11A is provided at a portion that comes into contact with the shoulder of the wearer.

In this example, when the wearer wears the belt 11 on the shoulder to carry the video camera 1, the part located on the back side of the wearer (for example, the mounting portion 12 side) and the chest side. The portion located at (for example, the mounting portion 1
(3 side) is provided with a bridge portion 15 for connecting the bridge.

In this example, the bridge portion 15 is made of the same member as the belt 11 (it is also possible to make different flexible members), and both end portions 16 and 17 thereof are the belt 1.
It is joined to 1 by, for example, suturing.

The bridge portion 15 has its both end portions 16 and 17 fixed to the belt 1 by fixing members as will be described later.
It may be attached to one body portion. Also, both ends 1
Although 6 and 17 are joined to the belt 11 by suturing or the like, they may be joined at a middle portion of the bridge portion 15 into two and joined by a fixing member such as a buckle. In that case, the bridge portion 1
The length of 5 can be adjusted.

Due to the above configuration, FIG.
As shown in, the shoulder belt 11 has a bridge portion 1
The presence of 5 forms the loop portion 14. By forming the loop portion 14 in this manner, even if the first attachment portion 12 and the portable portable object 9 are coupled due to breakage of the hook or the like, as shown in FIG. 2B, they may come off. Due to the existence of the loop portion 14, the belt 11 does not come off the shoulder as shown in FIG. 2C.

For this reason, the length of the bridge portion 15 is set as shown in FIG.
If the length is set so that the portable object 9 such as the video camera 1 does not come into contact with the ground even in the state of C, the second attachment portion 13 and the portable object can be separated from each other. As long as the connection is maintained, it is possible to prevent the portable object 9 such as the video camera body 1 from falling to the ground and being damaged.

In this case, the force applied to the connecting portion between the second mounting portion 13 and the portable portable object 9 which are connected to each other depends on the momentum of the portable portable object 9, and the portable portable object 9
The momentum due to the difference in the center-of-gravity position is determined by the product of the mass and the square of the velocity, so the smaller the difference is, the smaller the momentum. When the shoulder belt 11 according to the present invention is used, the portable object 9 contacts the ground as shown in FIG. 2C from the state of being carried by the shoulder belt 11 as shown in FIG. 2A. When falling by a distance that does not occur, the momentum is relatively small in view of the average height of a human being, and if the connecting portion between the second mounting portion 13 and the portable object 9 is designed with a certain safety factor. It is sufficiently possible to temporarily support a portable object such as a video camera.

FIG. 3 shows another embodiment of the shoulder strap according to the present invention, which is an example in which the shoulder strap is attached to a compact home video camera. In this example, one end portion 22 of one flexible belt 21 is joined to the intermediate portion of the belt 21 by stitching so as to leave the first attachment portion 23, and the loop portion 24 is formed. Then, the second attachment portion 25 is fixed to a part of the loop portion 24 by a fixing metal fitting 26 such as a buckle.

In the case of this example, a portion 27 of the loop portion 24 between the connecting portion of the fixing metal fitting 26 and the loop portion 24 and the stitched portion of the one end portion 22 of the belt 21 is the bridge portion of the example of FIG. Equivalent to 15. The length of this bridge portion 27 is
It is possible to adjust the second mounting portion 25, which is joined to the belt 21, by the fixing metal fitting 26 depending on which position of the loop portion 24 of the belt 21 is fixed.

In the above example, the bridge portion 15 or 27 is constructed to have a predetermined length.
As shown in the schematic view of FIG. 4, the bridge portion 33 may have a substantially zero length. That is, for example, one belt may be U-shaped, and the portion at the position 33 may be fixed with a metal fitting or the like in a state where the mounting portions 31 and 32 are formed as shown in FIG.

By the way, the loop is formed from the beginning from the beginning, and the first and second attaching portions are connected to each other, and the loop and the first and second attaching portions are connected by one connecting cord or the like. A shoulder belt configured to be connected to the connecting portion may be considered, but it is difficult to carry a portable object with one connecting cord. On the other hand, like the present invention,
When the bridge portion is formed, it is possible to stably hold a portable object.

The bridge portions 15 and 2 for the belt
The formation position of 7 does not have to be in the vicinity of the first and second attachment parts as long as the shoulder of the wearer can fit in the loop part formed by providing the bridge part.

Further, in the example of FIG. 3, the second mounting portion 25 may be constituted by a member different from the belt. For example, a rigid rod-shaped member may be used instead of the flexible member.

Further, although the example in which the shoulder belt is separated from the portable object has been described above, the invention is that the shoulder belt is attached to the first and second attachment parts by the fixing metal fittings and the sewing. It is, of course, applicable to a portable object that is connected to it in a non-detachable state.

[0023]

As described above, according to the present invention, the shoulder belt is provided with the bridge portion connecting the portion located on the chest side and the portion located on the back side when the belt is hung on the shoulder. Since it is provided and configured to form the loop portion, even when the engagement with the portable portable object is disengaged in one of the first and second attachment portions,
With this loop portion, it is possible to prevent an accident that the portable portable object falls to the ground.

The present invention is particularly effective in the case of an expensive portable portable object having a large mass, such as a professional video camera for a broadcasting station. Even in the case of a lightweight home video camera, one of the attachment parts such as hooks may be damaged while walking in crowded people, or the buckle at the connecting part with the shoulder belt may come loose. Even when it is lost, the same action and effect are exhibited, and the strange feeling due to the fact that it is pulled out makes it possible to notice the accident of disengagement between the belt and the portable object, and the camera or the like can be kept safe.

Further, the shoulder belt according to the present invention has an advantage that the user can feel a sense of security by using the shoulder belt in addition to the case where the actual accident as described above is encountered.
