Description

The present invention relates to a harness-type safety belt that is worn by a worker on the body when working at a high place to prevent a fall, and more particularly to a joint portion that connects a body belt to the harness-type safety belt.

There are two types of safety belts for preventing falls: harness type safety belts and torso belt type safety belts. Harness type safety belts that hold multiple main parts of the wearer's body such as shoulders and thighs when preventing a fall. Compared to the torso belt type safety belt that prevents the body from crashing at one place on the torso, the burden on the human body during and after the fall is less, so in recent years, the harness type safety belt has replaced the torso belt type safety belt. The belt has spread rapidly.
This harness type safety belt is classified into two types of harness type safety belts, X type and Y type, depending on the difference in the belt shape from the shoulder to the back.

The X-shaped harness type safety belt is composed of a shoulder belt and a thigh belt as shown in FIG. 5, and one shoulder belt is hung from the vicinity of the wearer's right waist through the chest and hung on the right shoulder on the back. It is connected to the thigh belt that passes through the center and is wound around the left thigh near the left waist, and the other shoulder belt is hung from the vicinity of the wearer's left waist through the chest to the left shoulder and passes through the center of the back. It is a harness type safety belt that is connected to a thigh belt that is wound around the right thigh near the right waist, and when the wearing state is viewed from behind the wearer, the shoulder belts intersect at the back and are just X-shaped.
Like the X-type harness type safety belt, the Y-type harness type safety belt consists of a shoulder belt and a thigh belt, but the right side is hung from the upper part of the wearer's right thigh through the chest to the right shoulder. The shoulder belt and the left shoulder belt, which is hung from the upper part of the left thigh through the chest to the left shoulder, are united at the center of the back and overlapped to extend to the buttock, where each belt is separated from the left thigh. It is connected to the thigh belt that is hung on the left thigh at the upper part and the thigh belt that is hung on the right thigh at the upper part of the right thigh. Since it extends to the buttocks, it is a harness-type safety belt with a Y-shaped back.

When the workers had tools and parts necessary for the work, they attached a tool case and a parts storage bag that could attach and store them to the torso belt type safety belt. When this worker works at a high place, it is desired to wear a harness-type safety belt having excellent safety performance rather than connecting the runlard to the torso-belt-type safety belt to be worn. In that case, both the torso belt type safety belt and the harness type safety belt were worn at the same time.

However, if the harness type safety belt is mounted on the harness type safety belt or the harness type safety belt is mounted on the body belt, the load can be supported by the shoulder belt even if the tool is hung on the body belt because it is not integrated. However, it was not easy to use.
There is also a harness-type safety belt in which the shoulder belt, thigh belt, and body belt are integrated, but when it is not necessary to wear the harness-type safety belt when working on the ground, or when working at heights where tools are not required, the body The harness-type safety belt and the integrated safety belt, which cannot be easily attached and detached from the body belt, were not easy to use, such as when it was not necessary to wear a belt.
For this reason, a harness-type safety belt has been invented that allows the body belt to be easily attached and detached.

The X-type harness-type safety belt of Patent Document 1 (Practical New Design Registration No. 3190133) was invented as a device that allows the body belt to be easily attached to and detached from the harness-type safety belt. In this safety belt, the lower end of the shoulder belt and the upper end of the thigh belt are polymerized at predetermined positions, that is, at both waists, and the central portion of the binding belt in which the socket body is fixed at one end and the tongue plate is fixed at the other end is attached to the polymerized portion. It is polymerized in the vertical direction and sewn. When attaching the torso belt to this harness type safety belt, it can be connected by arranging the torso belt in the overlapping portions on both sides and inserting the tongue plate into the socket body of the binding belt.
As described above, when the harness type safety belt shown in Patent Document 1 is used, the tools of the body belt on which the tools and the like are attached can be attached to the harness type safety belt without removing the tools from the body belt.

Further, in Patent Document 2 (Japanese Patent Laid-Open No. 2017-42358), a coupling tool for connecting a body belt to a harness type safety belt has been invented.
This coupling tool is mainly used by attaching it to a Y-shaped harness type safety belt, and has a structure in which two hooking bodies that hook near the waist of the shoulder belt of the harness type safety belt are connected by a connecting tool. The hanging body has a substantially rectangular outer shape, is provided with two insertion holes orthogonal to the connector and parallel to each other, and is provided with an opening having a predetermined length on the central side located between the two insertion holes. , The connector is composed of two overlapping belts of a predetermined length, and is provided with a gap for arranging the trunk belt between the two belts. Is.
Two locking bodies are locked near the waist of both shoulder belts, and the torso belt is placed in the gap formed between the connector and the harness type safety belt or in the gap between the two overlapping belts. By sandwiching it, the harness type safety band and the torso belt can be connected.
As described above, by using this coupling tool, it is possible to attach the tool bag and tools attached to the body belt to the harness type safety belt without removing them.

Utility model registration No. 3190133 JP-A-2017-42358

The harness type safety belt of Patent Document 1 is attached to the body belt by winding the body belt around the binding belt equipped on the harness type safety belt and inserting the tongue plate at the other end of the binding belt into the socket body at one end of the binding belt. Both waists of the body belt can be connected with a binding belt without removing the removed tools.

However, since this binding belt for attaching the body belt is not equipped on all harness type safety belts, workers who have the body belt or the body belt type safety belt can newly attach the binding belt for attaching the body belt. You must purchase a harness-type safety belt equipped with.

Further, the coupling tool for connecting the body belt to the harness type safety belt shown in Patent Document 2 is attached at a position where the shoulder belt and the body belt of the harness type safety belt intersect at the time of attachment, and the body is connected at the connecting portion of the coupling tool. By sandwiching the belt, the harness type safety belt and the body belt can be connected.

There are two types of this harness type safety belt, Y type and X type. In the case of the Y type harness type safety belt, the harness type safety belt and the shoulder belt of the harness type safety belt are attached to the body belt. Since the torso belts are substantially orthogonal to each other, the angle between the connecting portion of the fitting (the holding point of the torso belt) and the torso belt is almost perpendicular, and the torso belt can be attached in a state orthogonal to the shoulder belt.

However, in the case of the X-type harness type safety belt, as shown in FIG. 7, the shoulder belt and the torso belt have an angle of about 60 degrees in the mounted state.
Therefore, when the torso belt is attached to the harness type safety belt by this tying tool, the tying tool is arranged parallel to the shoulder belt of the harness type safety belt, so that the torso belt arranged vertically to the tying tool is the harness type safety belt. The angle with the belt will be about 30 degrees.
As a result, when the torso belt is attached to the harness type safety belt by this binding tool, the shoulder belt or the torso belt becomes twisted, and the usability deteriorates.

In addition, since the belt is placed from the shoulder to the thigh of the wearer in the harness type safety belt, the wearer is in a forward bent posture, a crouched posture, or a twisted posture when working or moving. When the shoulder belt and thigh belt are usually bent at the wearer's waist. At this time, if the harness type safety belt and the body belt are used in a state of being connected by using the binding tools of Patent Document 1 and Patent Document 2, the shoulder belt or the body belt is in a twisted state, and the usability is poor.

Can be rotatably connected.

FIG. 2 is an explanatory view showing a state in which the harness type safety band (shoulder belt 51) and the body belt 55 are connected by using the harness type body belt attachment 1 of the present invention, and FIG. 3 shows the shoulder belt 51 of FIG. FIG. 4 is an arrow view of A in a state where the first hook 10 is attached to the belt, and FIG. 4 is a view of arrow B in a state where the second hook 20 is attached to the body belt 55 of FIG.
FIG. 5 is an explanatory view of a state in which the harness body belt attachment 1 of the present invention is attached to the shoulder belt 51 of the X-type harness type safety belt, and FIG. 6 is an X-type harness body belt attachment 1 of the present invention. It is explanatory drawing of the state which attached to the harness type safety belt of the above, and attached the body belt 55.

As shown in FIGS. 5 and 6, in the harness body belt attachment 1, the first hook 10 is attached to the shoulder belt 51 of the harness type safety belt 50 (see FIG. 5), and then the second hook body 10 is attached. The body belt 55 is attached to the hook 20 (see FIG. 6).
As a method of attaching the first hook 10 to the shoulder belt 51, as shown in FIG. 2, the shoulder belt 51 is bent so as to form a small loop in the Y-axis direction (the length direction of the belt), and the first The left side portion of the shoulder belt 51 is hung on the left side first protrusion piece 17 and the right side portion is on the right side first protrusion piece 17 by passing through the gap from below the first protrusion piece 17 and 17 of the hooking body 10 and passing upward. Hang on one piece 17.
As a result, as shown in FIG. 3, the shoulder belt 51 has the back surface of the first belt width direction side 12a of the first hook body 10, the front surface of the first protrusion pieces 17 and 17, and the first belt width direction side 12b. Since it is sandwiched between the back surfaces, the harness body belt attachment 1 is attached to the shoulder belt 51 as shown in FIG.

Next, the body belt 55 is attached to the second hook 20. Similar to the case where the first hook 10 is attached to the shoulder belt 51, the body belt 55 is attached in the X-axis direction as shown in FIG. Bend so as to form a small loop, pass through the gap from below the second protrusions 27, 27 of the second hook 20 and pass upward, and pass the upper part of the body belt 55 to the upper second protrusion piece. Hang on 27, and hang the lower part on the lower second protrusion piece 27. As a result, as shown in FIG. 4, the body belt 20 has the back surface of the second belt width direction side 22a of the second hook body 20, the front surface of the second protrusion pieces 27, 27, and the second belt width direction side 22b. It is sandwiched on the back side. Therefore, the second hook 20 can be attached to the body belt 55. (See Fig. 6)

In this way, the harness type safety belt and the body belt can be connected by using the harness body belt attachment 1 of the present invention. Then, the wearer slides the first hook 10 on the shoulder belt 51 so that the body belt 55 is at the mounting position of the waist, and positions the body belt 55.
FIG. 6 shows a state in which the harness body belt attachment 1 is attached to the X-type harness type safety belt and the body belt 55 is further attached.

Since the body belt attachment 1 for the harness has the first hook 10 for attaching the shoulder belt and the second hook 20 for attaching the body belt rotatably attached via the shaft 41. As shown in FIG. 2, the shoulder belt 51 is not parallel to the Y axis, but the body belt 55 is caused by the rotation of the first hook body 10 and the second hook body 20 around the shaft 41. Is mounted in the X-axis direction. Therefore, in the wearing state shown in FIG. 7, the shoulder belt 51 extends from the front of the chest to the waist and is not orthogonal to the torso belt 55, but the first hook 10 attached to the shoulder belt 51 and the torso. Since the second hook 20 attached to the belt 55 is rotatably attached to the shaft via the shaft 41, the body belt 55 can be attached at an angle familiar to the wearer's body portion.

In the harness type safety belt, a belt is arranged from the wearer's shoulder to the thigh.
When the wearer wears a harness-type safety belt without a torso belt, the shoulder belt and thigh belt are above the wearer's waist when the wearer is in a forward-bent or crouched posture during work or movement. Since it gradually bends from the beginning, the wearing feeling is not significantly impaired.
However, when the harness type safety belt and the torso belt are worn together, the torso belt is firmly attached approximately horizontally to the height of the wearer's hipbone, and even if the wearer's working posture changes. Since the mounting position of the torso belt does not move, the thigh belt of the harness type safety belt bends at a large angle from the lower side of the torso belt, and the wearing feeling is poor.

For example, in the case of a normal harness type safety belt, since the thigh belt is a flat belt having a width of about 45 mm, it bends freely in the thickness direction but does not bend in the width direction. Therefore, when the wearer wears the torso belt and the harness type safety belt and is in a forward bent posture, the entire surface of the thigh belt does not come into close contact with the thigh, and one edge in the width direction is the front side. It is pulled by the leg and pressed against the thigh, and the edge of the other thigh belt is bent away from the thigh. This state is not comfortable for the wearer. In addition, when the thigh is bent, the thigh is pulled by the thigh belt, and there is a feeling of resistance.

Even when the binding tools of Patent Document 1 and Patent Document 2 are used, the harness type safety belt and the torso belt are fixedly and orthogonally connected at the waist, so that the operator bends forward during work or movement. When the person is in a crouched position, the thigh belt bends at a large angle from the lower side of the wearer's waist as described above, and the wearing feeling is poor, and the thigh is pulled by the thigh belt and there is a feeling of resistance. ..

In the harness body belt attachment 1, the first hook 10 attached to the shoulder belt 51 and the second hook 20 attached to the body belt 55 are rotatably attached to the shaft via the shaft 41. However, since the first hook 10 is attached to the shoulder belt 51 above the mounting position of the torso belt, the torso is in a forward bent or crouched posture when the wearer is working or moving. Since the belt can move from the mounting position of the first hook 10 according to the posture of the worker, the wearing feeling is not impaired and there is no resistance that the thigh is pulled by the thigh belt.

Although not shown, in the Y-shaped harness type safety belt, the shoulder belt is substantially parallel to the Y axis in the worn state, so that the body belt can be attached in the X axis direction.
As described above, even if the shape of the harness type safety belt is changed, by using the harness body belt attachment 1 of the present invention, the body belt can be securely wound around the wearer's waist and attached.

As the material of the harness body belt attachment 1, a resin may be used, or a metal material such as steel or an aluminum alloy may be used.

(Second Example)
In the harness body belt mounting tool 1 of the first embodiment, the second hooking body 20 has a flat plate shape, and the first connecting member mounting piece 15 of the first hooking body 10 for axially mounting the hook body 20. Reference numeral 15 is a structure in which an insertion hole 19 into which a second connecting member of the second hook can be inserted is provided in the central portion thereof.
In the second embodiment, as shown in FIG. 12, the first hooking body 10 has a flat plate shape, and the second hooking body 10 for axially mounting the first connecting member mounting piece 15 of the first hooking body 10. The second connecting member mounting piece 25 of the stop body 20 has a structure in which an insertion hole 29 into which the first connecting member mounting piece 15 of the first hooking body 10 can be inserted is provided in the central portion thereof.
The first connecting member mounting piece 15 is inserted into the insertion hole 29 in the central portion of the second connecting member mounting piece 25, and the first shaft hole 16 and the second connecting member mounting piece 25 provided in the first connecting member mounting piece 15 are provided.
