In the safety belt 2, the main belt 4 and the back side belt 6 are non-detachably connected via an integrated belt 8. - 特許庁Thereby, when the back side belt 6 is attached, the main belt 4 is attached. That is, when performing slope work requiring the back side belt 6, the main belt 4, which is connected in a non-detachable state, is also attached. This means that the main belt 4 must be worn to prevent accidents such as falls. This safety belt 2 is excellent in safety.

In this safety belt 2, the integrated belt 8 has a belt-side overlapped portion 34b at a position where it intersects with each shoulder belt 28. As shown in FIG. The shoulder belt 28 is passed through and connected to the belt-side overlapping portion 34b. The opening width of the belt-side overlapping portion 34b is larger than the width of the shoulder belt 28. As shown in FIG. The shoulder belt 28 can be moved with respect to the belt-side overlapped portion 34b within the range of the difference between the opening width of the belt-side overlapped portion 34b and the width of the shoulder belt 28. As shown in FIG. Thereby, the arrangement position of the integrated belt 8 can be adjusted with respect to the main belt 4 . The arrangement position of the back side belt 6 can be adjusted with respect to the main belt 4. - 特許庁As a result, fine adjustment of the position of the back side belt 6 is facilitated according to the body shape of the wearer, although it is connected in a non-detachable state.

When the wearer changes posture by bending forward or twisting the body during work, the front shoulder belt portion 28a or the rear shoulder belt portion 28b arranged along the body is pulled in the direction of the shoulder. At this time, in the safety belt to which the crossing portion of the main belt 4 is sewn and fixed, the crossing portion of the main belt 4 is pulled toward the shoulder by the pulled front shoulder belt portion 28a or the rear shoulder belt portion 28b. Such a safety belt impairs the feeling of wearing, restrains the wearer from changing his or her posture, and makes the wearer feel annoyed. On the other hand, in the safety belt 2, the front harness overlapping portion 28h and the rear harness overlapping portion 28m are passed through each other, so that the front shoulder belt portion 28a or the rear shoulder belt portion 28b can follow the change of posture of the wearer. to move. This safety belt 2 does not impair the feeling of wearing.

In this safety belt 2, the end suspension belt 10 connected to the backside belt 6 has an end suspension overlapping portion 10b. The end suspension overlapped portion 10b and the belt side overlapped portion 34b are passed through each other to connect the back side belt 6 and the integrated belt 8 together. As a result, the position of the backside belt 6 can be easily adjusted with respect to the integrated belt 8 even when the belts are connected in a non-detachable state.

The main belt 4 includes a front harness overlapped portion 28h and a rear harness overlapped portion 28m which are sewn to intersect the integrated belt 8 and formed in an annular shape. The belt-side overlapped portion 34b, the front harness overlapped portion 28h, and the rear harness overlapped portion 28m are passed through each other. Thereby, the integrated belt 8 and the main belt 4 regulate the range in which they can move relative to each other. Thereby, the positional relationship between the main belt 4 and the integrated belt 8 is regulated within a predetermined range. In this safety belt 2, the positional relationship between the main belt 4 and the integrated belt 8 is adjustable, and the positional relationship is maintained within a predetermined range. By maintaining this positional relationship within a predetermined range, attachment and detachment of the safety belt 2 is facilitated.

The safety belt 2 includes a waist suspension belt 26 that connects the central portion of the integrated belt 8 in the left-right direction and the rear crossing portion 28e. By providing the trunk suspension belt 26 , the integrated belt 8 is prevented from shifting from a predetermined position with respect to the main belt 4 .

Furthermore, the trunk suspension overlapped portion 26b and the belt center overlapped portion 34a are passed through each other, and the trunk suspension belt 26 and the integrated belt 8 are connected. While the positional relationship between the waist belt 26 and the integrated belt 8 is adjustable, the positional relationship is maintained within a predetermined range.

In this safety belt 2, a lifeline is connected to the connecting ring 14c of the connecting belt 14. As shown in FIG. Since the front crossing portion 28d is provided, tension is generated in the longitudinal direction of the shoulder belt 28 in the main belt 4 when the connecting belt 14 is pulled. This prevents the pair of shoulder belts 28 from being pulled toward each other inward in the left-right direction. As a result, even if the main belt 4 is pulled by the connecting belt 14, the wearer's body is prevented from being pressed by the pair of shoulder belts 28 being drawn inward in the left-right direction.

A wearer of the safety belt 2 bends forward or twists the body during work. During such work, the wearer's waist is at the center of the working body. Therefore, the amount of movement of the waist of the wearer is smaller than that of other parts. In this safety belt 2, since the side crossing portions 28c are positioned at the left and right hips of the wearer, the amount of movement of the side crossing portions 28c is small. In this safety belt 2, the lateral crossing portion 28c is prevented from changing its position significantly when the wearer moves. The safety belt 2 prevents the main belt 4 from being pulled by the action of the wearer and impairing the feeling of wearing. In addition, the main belt 4 is suppressed from interfering with the change of posture of the wearer.

The safety belt 2 has a pair of end hanging belts 10 extending upward from the left and right ends of the back side belt 6 . In each of the end suspension belts 10, the end suspension overlapping portions 10b are arranged so as to overlap the left and right side crossing portions 28c. Thus, in the safety belt 2, the backside belt 6 can be arranged to wrap the back and sides of the buttocks of the wearer who rests his or her weight on the slope.

In this safety belt 2 , the end hanging overlapping portion 10 b of the end hanging belt 10 is passed through the outer belt portion 34 c of the integrated belt 8 . The front harness overlapping portion 28 h and the rear harness overlapping portion 28 m of the main belt 4 are passed through the inner belt portion 34 d of the integrated belt 8 . As a result, the end suspension overlapped portion 10b, the front harness overlapped portion 28h, and the rear harness overlapped portion 28m can be arranged at overlapping positions. The end suspension overlapped portion 10b, the front harness overlapped portion 28h, and the rear harness overlapped portion 28m do not restrict mutual movement in the longitudinal direction of the integrated belt body 34. As shown in FIG. This safety belt 2 is excellent in wearing feeling.

The safety belt 2 has a front crossing portion 28d and a rear crossing portion 28e. As described above, in the safety belt 2, even if the connecting belt 14 is pulled, the position of the pair of shoulder belts 28 is unlikely to shift. Similarly, even if the connecting ring positioned at the rear crossing portion 28e is pulled backward, the position of the pair of shoulder belts 28 is less likely to shift. This prevents the wearer's body from being pressed by the pair of shoulder belts 28 regardless of whether the main belt 4 is pulled forward or backward. Furthermore, the provision of the front crossing portion 28d and the rear crossing portion 28e makes it difficult for the safety belt 2 to come off. This safety belt 2 is excellent in safety.

The safety belt 2 includes a buckle 16 that detachably connects one shoulder belt 28 . One shoulder belt 28 is detachably connected between the front crossing portion 28d and the belt-side overlapping portion 34b of the integrated belt 8. As shown in FIG. By releasing the connection of one shoulder belt 28 with this buckle 16, the wearer can easily put his/her head between the pair of shoulder belts 28 between the front crossing portion 28d and the rear crossing portion 28e. It's becoming While the safety belt 2 is difficult to come off as described above, it is also easy to put on.

The buckle 16 is preferably provided on at least one of the shoulder belts 28 from the viewpoint of facilitating wearing. From the viewpoint of facilitating attachment and detachment, the buckle 16 is preferably attached to the front shoulder belt portion 28a, and more preferably attached to the front shoulder belt portion 28a between the front cross portion 28d and the belt-side overlapping portion 34b of the integrated belt 8. be provided.

Also, the buckle 16 is preferably provided on the front shoulder belt portion 28a between the side crossing portion 28c and the front crossing portion 28d rather than on the folded portion of the shoulder belt 28. As shown in FIG. Even when the shoulder belts 28 are disconnected by the buckles 16, the safety belt 2 can be supported on the wearer's shoulders by the pair of shoulder belts 28 between the front crossing portion 28d and the rear crossing portion 28e. This makes it easy to attach and detach the safety belt 2 . From this point of view, the buckle 16 may be provided on the rear shoulder belt portion 28b between the side crossing portion 28c and the rear crossing portion 28e.

The safety belt 2 is worn in a state in which one of the pair of shoulder belts 28 is disconnected and the other is connected. This allows the safety belt 2 to be supported on the shoulders of the wearer. When both the pair of shoulder belts 28 are disconnected, the safety belt 2 cannot be supported by the wearer's shoulders. Moreover, the safety belt 2 in which one of the pair of shoulder belts 28 is disconnected can maintain a form close to the worn state even when worn. The safety belt 2 is easier to wear when one of the connections is released. It is preferable to provide the buckle 16 on either one of the shoulder belts 28 from the viewpoint of not accidentally disconnecting both of the pair of shoulder belts 28 when worn.

As shown in FIG. 9, in the safety belt 42, the lower end of the front shoulder belt 28a and the lower end of the rear shoulder belt 28b are sewn to the thigh belt 30. As shown in FIG. By this sewing, the shoulder belt 28 and the thigh belt 30 are connected. Although not shown in the safety belt 2 of FIG. 1, the shoulder belt 28 and the thigh belt 30 are sewn on like the safety belt 42 .

FIG. 10 shows the waist bag 46 and the pliers case 48 along with the safety belt 42 . FIG. 10 shows the safety belt 42 viewed from the back.

The waist bag 46 is a bag for storing tools and parts. The waist bag 46 has a main body 46a and a belt loop 46b. A waist belt body 44a is passed through a belt loop 46b of the waist bag 46. - 特許庁The waist bag 46 is worn by inserting the waist belt main body 44a from one opening of the belt loop 46b to the other opening. The waist belt body 44a is pulled out from the belt loop 46b, and the waist bag 46 is removed. The waist bag 46 cannot be attached to or detached from the waist belt body 44a unless the waist belt body 44a is removed from the through ring 36. - 特許庁

The pliers case 48 is a case that accommodates tools such as pliers. The pliers case 48 has a main body 48a and a belt loop 48b. Like the belt loop 46b, the belt loop 48b cannot be attached to or detached from the waist belt main body 44a unless the waist belt main body 44a is removed from the through ring 36. As shown in FIG.

In FIG. 10, a waist bag 46 and a pliers case 48 are attached to the waist belt body 44a between the waist suspension overlapping portion 26b of the waist suspension belt 26 and the through ring 36. As shown in FIG.

This safety belt 42 has a waist belt 44 . The waist belt 44 is passed through the through ring 36 of the integrated belt 8 . The integrated belt 8 is attached to this waist belt 44 . The waist belt 44 is worn around the wearer's waist. Thereby, the integrated belt 8 is securely positioned around the wearer's waist. By tightening the waist belt 44 around the waist, deviation of the determined positional relationship between the main belt 4 and the integrated belt 8 is suppressed.

In this safety belt 42, the waist belt 44 is passed through the waist-hanging overlapping portion 26b. As a result, even if the waist bag 46, the pliers case 48, and the like are attached to the waist belt 44, the weight of the waist belt 44 prevents the waist belt 44 from dropping. Furthermore, the safety belt 42 is provided with the central suspension belt 12, thereby preventing the back side belt 6 from moving downward.

A waist bag 46, a pliers case 48, and the like can be attached between the waist belt 44 and the loop 36. As shown in FIG. A waist bag 46, a pliers case 48, and the like can be attached to the safety belt 42 without being restricted by the side crossing portion 28c. With this safety belt 42, the range in which the waist bag 46 and the pliers case 48 can be attached is widened.

In the safety belt 42, the waist bag 46 and the pliers case 48 cannot be attached to or detached from the waist belt body 44a unless the waist belt body 44a is removed from the through ring 36.例文帳に追加This prevents the waist bag 46 and the pliers case 48 from coming off the waist belt 44 during high-place work.

On the other hand, the waist belt 44 is attached by being passed through the through ring 36 of the integrated belt 8 and the waist suspension superimposed portion 26b. Only this waist belt 44 can be attached and detached. By attaching and detaching the waist belt 44, the waist bag 46 and the pliers case 48 can be easily attached and detached.

The weight of the safety belt 42 to which the waist bag 46 and the pliers case 48 are attached is increased. This safety belt 42 has a buckle 16 for releasing the connection of the shoulder belt 28 . As described above, by releasing the connection of the buckle 16, the safety belt 42 can be easily worn. The safety belt 42 is supported by the wearer's shoulder when worn. The safety belt 42 can be worn relatively easily even when the weight is increased by supporting the wearer with the shoulder. The safety belt 42 can be easily worn even when the waist bag 46 or the pliers case 48 contains tools and parts.

The safety belt 42 connects the main belt 4, the backside belt 6, and the integrated belt 8 in a non-detachable manner. By sewing, the main belt 4, the backside belt 6, and the integrated belt 8 can move relative to each other while being connected in a non-detachable state. Further, the front shoulder belt portion 28a and the rear shoulder belt portion 28b of the main belt 4 are also relatively movable. As a result, the safety belt 42 is restrained from restricting the movement of the wearer. This safety belt 42 is excellent in wearability. Furthermore, since the range in which the main belt 4, the backside belt 6, and the integrated belt 8 can move relative to each other is restricted to a predetermined range, it is possible to prevent the shape from collapsing. The safety belt 42 is easy to put on and take off because the shape is suppressed from collapsing.

The harness-type safety belt for slopes described above can be widely applied to safety belts used for slope work.
