Description

  The present invention relates to a harness-type safety belt that is worn on the body by an operator during work at a high altitude to prevent a fall, and particularly relates to a coupler and a coupling method for coupling a torso belt to the harness-type safety belt. is there.

  There are a harness-type safety belt and a torso-belt safety belt as safety belts for preventing crashes, but a harness that holds the main part of the wearer's body, such as the shoulders, waist, and thighs, at multiple locations when preventing a crash. Since the type safety belt has less burden on the human body at the time of and after the fall prevention, the harness type safety belt has been rapidly increasing in recent years.

  When using a harness-type safety belt, it is not necessary to wear a torso belt-type safety belt as a fall prevention measure, but it is necessary to attach a waist bag, such as a sack bag or pliers, to store materials used in the work. I often wear a belt. In this case, it is desirable to combine the harness-type safety belt and the body belt so that it is easy to use and can be easily combined.

As a method of connecting the harness-type safety belt and the torso belt, a method of providing the harness-type safety belt with a belt threader for inserting and connecting the torso belt to the positions of both hip bones is common.
The belt threader for coupling the waist belt is provided on both waists of the harness-type safety belt, and the belt threader cannot be removed from the harness-type safety belt even when the body belt is not coupled.

There are various types of body belts that are coupled to the harness-type safety belt depending on the application.
The most standard belt belt has a width of 50 mm. In addition, when a lot of lumbar equipment is worn and the lumbar equipment is heavy, the torso belt is bent and the burden on the waist is large, so the contact with the waist is softened and the weight of the entire waist belt is shared in a wide area A supporter belt may be combined with a torso belt. The width of the supporter belt is typically 100 mm.
In order to suppress the bending of the waist belt caused by the worn waist tool, there is a waist belt having a width of 60 mm and a high rigidity.
In addition, there is a case where the safety belt on the pillar and the harness-type safety belt are combined, but the width of the safety belt on the pillar is typically 100 mm, which is the same as that of the supporter belt.
As described above, the widths of the majority of the body belts coupled to the harness-type safety belt are 50 mm, 60 mm, and 100 mm.

Japanese Patent No. 3769551 and Patent No. 5750333 disclose a method of connecting a harness-type safety belt and a body belt. All of the above-mentioned known inventions are assumed to be combined with a body belt having a width of 50 mm. In Japanese Patent No. 3853804 and Utility Model Registration No. 3190133, it is assumed that the belt is combined with a body belt having a width of 100 mm.
In any known invention, a body belt having a width limited to one kind is combined.

  The inventions of Patent No. 3769551, Patent No. 5750333, Patent No. 3853804, and Utility Model Registration No. 3190133 have members for attaching the waist belt on both waists of the harness-type safety belt, even when the waist belt is not coupled. The member cannot be removed from the harness-type safety belt.

Further, in the one belt threading tool, usually two long holes for inserting the belt of the torso belt are formed, and the harness-type safety belt is provided with two belt threading tools, for a total of four of the above-mentioned lengths. Insert the body belt through the hole and join.
The operator decides the type and position of the waist tool to be attached to the waist belt in consideration of workability, so the harness type safety belt and the waist belt are joined by the worker himself, and various waist tools and harness types are attached. It is necessary to insert the waist belt in order from the end of the waist belt into the four long holes of the belt threader of the safety belt.
In addition, when joining a waist belt with a waist tool already owned and used by an operator to a harness-type safety belt, it is necessary to remove the various waist tools equipped from the waist belt.
As described above, the joining work of the harness-type safety belt and the body belt is troublesome for the operator.

Utility Model Registration No. 3190133

  As described above, the following problems have not been solved in the conventional methods for connecting a harness-type safety belt and a body belt.

The conventional method of connecting a harness-type safety belt and a body belt does not support a plurality of body belts having different widths. Therefore, it is necessary to prepare a harness-type safety belt corresponding to the type of trunk belt that varies depending on the work content. Or when using a waist belt with a waist device already owned by the operator, the harness-type safety belt attached to the waist belt must be suitable for the width of the waist belt, and the user must The range for selecting the type of type safety belt is limited.

When using a torso belt with a waist device already owned by the operator and connecting the torso belt to a harness-type safety belt, remove the various waist devices from the torso belt and then remove the torso belt. It is necessary to insert the four elongated holes of the belt-type tool of the harness-type safety belt and various waist tools in order, and this work is very troublesome for the user.

Even the same worker may or may not need a torso belt depending on the work contents. However, as described above, the harness-type safety belt and torso belt coupling method disclosed heretofore, Since the belt cannot be easily attached to or removed from the harness-type safety belt, it is easier to work with a torso belt even when work is not required on the torso belt or to wear a torso belt with a waist device. Even when it was good, the work was sometimes performed without wearing the waist belt at the expense of workability, which was inconvenient.

In addition, the conventional harness-type safety belt is equipped with members for attaching the waist belt on both waists even when the waist belt is not coupled to the harness-type safety belt when an operation that does not require the waist belt is performed. It is a structure which cannot be removed from the harness type safety belt.
In high-altitude work where there is a risk of crashing, a harness-type safety belt that eliminates unnecessary parts as much as possible, is lightweight, has a good fit, and reduces the burden on the operator as much as possible is desired. A structure that can be removed from the harness-type safety belt is desired when a member that couples is not required.

In view of the problems of the prior art,
A plurality of belts with different widths can be combined,
The coupling tool for coupling the torso belt can be easily attached to and detached from the belt part of the harness-type safety belt according to the work contents,
In addition, when a torso belt is not required, there is no belt threader for attaching the torso belt to the harness type safety belt, so it can be used as a harness type safety belt that is lightweight and comfortable to wear.
Preferably, when the waist belt with the waist tool already used by the operator is coupled to the harness-type safety belt, it is not necessary to remove the various waist tools equipped from the waist belt at one end.

By combining the harness-type safety belt and the body belt with a plurality of body belts having different widths, the range of types of the harness-type safety belt selected by the user is expanded.
There is no need to limit the harness-type safety belt even when a different waist belt is used depending on the work content or when a waist belt with a waist tool already owned by the worker is used.

  When a torso belt is necessary or unnecessary depending on the work contents, the torso belt can be easily coupled and detached, which is effective in improving workability.

  In addition, if the coupling according to the present invention is detached from the harness-type safety belt in an operation that does not require a torso belt, unnecessary members are eliminated from the waist portion of the harness-type safety belt.

In the case of a coupler that does not need to be inserted from the terminal and can be connected to an arbitrary position of the torso belt, it can be easily connected to the torso belt with a waist tool already owned by the operator. Conventionally, after removing various waist tools equipped on the torso belt from the torso belt, there are four long holes in the belt threading tool for connecting the torso belt to the harness type safety belt. Although it was necessary to perform a very troublesome work for the user, that is, to sequentially insert various waist tools, this is not necessary in the present invention.

  Embodiments according to the present invention will be described below with reference to the drawings.

FIG. 1 is a front view and a side view of a state in which a coupler according to an embodiment of the present invention is mounted on a harness-type safety belt.
2, 3 and 4 are a front view and a side view of a state in which a coupler according to an embodiment of the present invention is mounted on a harness-type safety belt and a trunk belt is coupled.

As shown in FIG. 5, the coupler 3 for coupling the body belt 7 to the harness-type safety belt according to the present invention includes two locking bodies 31 (first locking body and second locking body). ), And the first locking body and the second locking body are connected by a connecting band 32.
The locking body 31 has a substantially rectangular outer shape, is provided with two insertion holes 312 that are orthogonal to the connector 32 and are parallel to each other, and a central side 313 located between the two insertion holes 312 is a center. By providing an opening having a predetermined length open, a substantially E-shaped insertion hole is formed together with the insertion hole.
For example, the locking body 31 has a substantially rectangular outer diameter, and the two insertion holes 312 are parallel, but the locking body 31 may be elliptical, and the two insertion holes 312 have two pairs of holes. It is good also as a shape which arrange | positioned the letter-shaped hole in parallel.
A connecting band 32 having a predetermined length is connected to the end side 314 adjacent to the other locking body 31 among the two end sides 311 and 314 positioned outside the substantially E-shaped insertion hole. The first locking body 31 and the second locking body 31 are coupled together.
The connection band 32 is composed of two overlapping bands, and a gap 321 for disposing the body belt 7 is provided between the two bands.
By inserting both ends of the connecting band 32 into the end side 314 of the two locking bodies 31 and folding them back, the two locking bodies 31 and the connecting band 32 are connected.
In addition to the method of sewing as described above, the connecting band 32 and the locking body 31 may be fixed with a scissors or heat welded.

The material of the locking body may be a metal such as steel or aluminum alloy, or may be plastic.
The coupling band may be a fiber belt or an elastic plastic.

  Generally, the body belt coupled to the harness-type safety belt has a width of 50 mm, a width of 60 mm, and a width of 100 mm with a supporter belt attached.

Hereinafter, the case where the body belt 7 equipped with the supporter belt 6 having a width of 100 mm is coupled to the harness type safety belt will be described.
As shown in FIG. 7, the coupler 3 is disposed at the intersection of the harness belt 1 and the body belt 7, and the two locking bodies 31 coupled by the coupling band 32 are disposed at positions above and below the intersection. To do.
In the lower first locking body 31, the two insertion holes 312 are arranged so that the harness belt 1 contacts the back surface of the lower end side 311, the front surface of the central side 313, and the back surface of the upper end side 314. The first locking body 31 is locked to the harness belt 1 by being inserted into the harness belt 1.
In other words, the harness belt 1 is folded and inserted into a U-shape through the substantially E-shaped insertion hole of the engagement body 31, and the engagement harness 31 is hooked on the central side 313, thereby engaging the engagement body 31. The harness belt 1 is locked.
The operation of locking the locking body 31 to the harness belt 1 is easy.

Next, as shown in FIG. 8, a body belt in which a supporter belt 6 having a width of 100 mm is mounted between the connector 32 and the harness belt 1 when connected to the first locking body 31 locked to the harness belt 1. 7 is disposed, the upper second locking body 31 is locked to the harness belt 1.
The method of locking the first and second locking bodies 31 to the harness belt 1 is that the harness belt 1 has the back surface of one end side 311 of the first locking body 31, the surface of the central side 313, and the other side. By being inserted so as to be in contact with the back surface of the end side 314.
By the above operation, the body belt 7 with the supporter belt 6 having a width of 100 mm is sandwiched between the gap 322 between the connector 32 and the harness belt 1, and the harness-type safety belt and the body belt are coupled.
At this time, the gap 322 of the coupler 32 is set to a length that matches the width of the body belt 7 to which the supporter belt 6 is attached. Thus, the coupling position of the body belt with respect to the harness-type safety belt is not easily shifted in the direction along the body belt, and the coupled state can be maintained.
When the width of the supporter belt 6 is different from 100 mm, the connecting tool 32 is set to a length that matches the width of the supporter belt 6.

Further, when the work is performed by attaching a harness-type safety belt to which the body belt 7 to which the supporter belt 6 having a width of 100 mm is attached is attached, the body belt 7 to which the supporter belt 6 having a width of 100 mm is attached and the harness belt 1. When the coupling position is shifted, each part of the worn body is shifted and the feeling of wearing is deteriorated, or the harness belt 1 above or below the torso belt 7 is slackened, and the harness belt 1 is caught on the protrusion of the structure. It will interfere with safety and workability.
In the coupling device and the coupling method according to the present invention, the harness belt 1 and the latching body that are largely bent and inserted through the latching body 31 when tension is applied to the harness belt 1 due to the weight of the harness-type safety belt or the like. Since a frictional force is generated between 32, the position where the locking body 31 is locked to the harness belt 1 does not easily shift in the direction along the harness belt 1, and the above problem does not occur.

After the trunk belt 7 is disposed at a predetermined position of the harness-type safety belt, the first and second locking bodies 31 are locked to the harness belt 1 and the trunk belt 7 is coupled to the harness-type safety belt. Even when the waist belt 7 to which a number of waist tools are attached is coupled, the troublesome operation of removing the waist tool from the waist belt 7 is not required.
The coupler according to the present invention does not need to be assembled to the harness belt 1 in advance when the harness-type safety belt is manufactured, and the coupler according to the present invention can be added to the harness-type safety belt and the trunk belt already owned by the user. Can be easily combined by the user. This is convenient for the user and economically preferable.
Also, in the manufacturing process when the harness type safety belt and the body belt are combined, the ends of the harness belt 1 are not inserted through the two insertion holes 312 of the locking body 31 in order, but both ends are opened. Since the latching body 31 can be latched to the harness belt 1 of the part which is not performed, the order of this assembly process is not limited within a manufacturing process. Moreover, the assembly process which concerns on a coupler is easy and manufacturing cost is reduced. This is economically preferable for the user as described above.

Next, a case where the body belt 7 having a width of 50 mm is coupled to the harness type safety belt will be described.
As shown in FIG. 7, the coupler 3 is disposed at the intersection of the harness belt 1 and the body belt 7, and two locking bodies 31 coupled by the coupler 32 are disposed at positions above and below the intersection. To do.
The harness belt 1 is inserted into the two insertion holes 312 so as to contact the back surface of the lower end side 311, the front surface of the central side 313, and the back surface of the upper end side 314 of the two locking bodies 31. As a result, the locking body 31 is locked to the harness belt 1.
As shown in FIG. 9, the torso belt 7 is inserted into the gap 321 between the ends of the band 32 of the connecting member 32 constituted by two overlapping bands, and the torso belt is harnessed by sandwiching the torso belt. Combined with type safety belt.
The gap 321 of the connector 32 is set to a length that matches the width of the body belt 7 having a width of 50 mm. As a result, the harness-type safety belt and the waist belt are not easily displaced in the direction along the waist belt, and the joined state can be maintained.

Similarly to the case where the body belt 7 to which the supporter belt 6 is attached is coupled to the harness-type safety belt, the position where the locking body 31 is locked to the harness belt 1 is easily shifted in the direction along the harness belt 1. There is nothing.
Furthermore, the coupler according to the present invention does not need to be assembled to the harness belt 1 in advance when the harness-type safety band is manufactured, and if the coupler according to the present invention is added to the harness-type safety band already owned by the user. Easy to install.

  However, in the case of the structure described above, when connecting a waist belt 7 having a width of 50 mm to which a large number of waist tools are mounted, the waist belt 7 is removed from the waist belt 7 and is composed of two belts. The body belt 7 must be inserted into the gap 321 of the connecting tool 32 from the end, and a troublesome operation is required.

Therefore, another coupler 3b according to the present invention will be described.
As shown in FIG. 11, the coupling tool 32b constituting the coupling tool 3b is composed of three overlapping belt bodies, and two adjacent belt bodies among the three belt bodies, that is, the first belt body. The belt body and the second belt body are respectively provided with the hook surface and the loop surface of the surface fastener 323b, and the third belt body is not provided with the surface fastener.
A gap 321b for disposing the body belt 7 is provided between the first and second belt bodies.
The overlapping portion of the first belt body and the second belt body can be attached and detached by a hook-and-loop fastener 323b, the hook-and-loop fastener 323b is opened, and a gap 321b between the first and second belt bodies is provided. After the trunk belt 7 is disposed, the surface belt 323b is joined to join the trunk belt to the coupler 3b.
Since the gap 321b is opened by dissociating the hook surface and loop surface of the hook-and-loop fastener 323b, it is easy to dispose or remove the waist belt 7 in the gap 321b.

Next, another coupler 3c according to the present invention will be described.
As shown in FIG. 12, the coupling tool 32c constituting the coupler 3c is composed of three overlapping belts, and two adjacent belts among the three belts, ie, the first belts. The belt body and the second belt body are respectively provided with the convex part and the concave part of the hook 323c, and the third belt body is not provided with a hook.
A gap 321c for disposing the body belt 7 is provided between the first and second belt bodies.
The overlapping portion of the first belt body and the second belt body is detachable by a hook 323c, the hook 323c is opened, and a gap 321c between the first belt body and the third belt body is formed. After the trunk belt 7 is arranged, the trunk belt is coupled to the coupler 3c by fastening the hook 323c.
Since the gap 321c is opened by dissociating the convex portion and the concave portion of the hook 323c, it is easy to dispose or remove the waist belt 7 in the gap 321c.

  Therefore, in the case of the couplers 3b and 3c having the coupling tool 32b and the coupling tool 32c, the harness-type safety belt and the body belt having a width of 50 mm can be obtained without removing the waist tool from the waist belt 7 on which many waist tools are mounted. Can be combined.

  The coupling tool 3b and the coupling tool 3c have a structure in which the coupling tools 32b and 32c can be opened by the hook-and-loop fasteners and hooks so that the belts can be easily attached and detached. Instead of the hook, the first band and the second band may be connected by a buckle.

Next, a case where the body belt 7a having a width of 60 mm is coupled to the harness type safety belt will be described.
As shown in FIG. 10, the coupling tool 3 according to the present invention is arranged at the intersection of the harness belt 1 and the body belt 7a, and the two latches connected by the coupling tool 32 in the vertical direction of the intersection. It arrange | positions so that the edge part edge | side 314 of the body 31 may each be located in a far side, and the edge part edge | side 311 of the two latching bodies 31 may each be located in the near side.
The harness belt 1 is inserted into the two insertion holes 312 so as to be in contact with the back surface of the lower end side 314, the front surface of the central side 313, and the back surface of the upper end side 311 of the lower locking body 31. Thus, the locking body 31 is locked to the harness belt 1.
Next, as shown in FIG. 10, in the state where the lower locking body 31 locked to the harness belt 1 is locked, the torso belt 7a is disposed between the harness belt 1 and the connector 32, and the upper locking mechanism 31 is connected. The stop 31 is locked to the harness belt 1. At this time, the method of locking the upper locking body 31 to the harness belt 1 is the same operation as that of the lower locking body 31.

When the body belt 7a having a width of 60 mm is coupled to the harness-type safety belt, the gap 322 between the connector 32 and the harness belt 1 is set to a length that matches the width of the body belt 7a having a width of 60 mm. The mold safety belt and the body belt 7a are not easily displaced in the direction along the body belt, and can maintain the coupled state.
The position where the locking body 31 is locked to the harness belt 1 does not easily shift in the direction along the harness belt 1.
Further, the coupler according to the present invention does not need to be assembled to the harness belt 1 in advance at the time of manufacturing the harness-type safety belt, and the coupler according to the present invention is added to the harness-type safety belt already possessed by the user. Can be easily installed.
Further, the connecting tool 32 can connect the harness-type safety belt and the 60 mm wide belt 7a without removing the waist tool from the waist belt 7a on which many waist tools are mounted.

Another embodiment of the coupler according to the present invention will be described.
As shown in FIG. 15, the coupling tool 3d includes two locking bodies 31d and a coupling tool 32d. The locking body 31d has a substantially rectangular outer shape, is orthogonal to the coupling tool, and is horizontally long and parallel to each other. Two insertion holes 312d are provided, and the two insertion holes 312d are provided with openings having a predetermined length on the end side 311d and the connection side end side 314d that are located on the outer sides, and the two insertion holes 312d. A coupling tool 32d having a predetermined length is connected to a central side 313d located between the two locking bodies 31d, and the coupling tool 32d is composed of two overlapping belts, A gap 321d for disposing the body belt 7 is provided between the two belts.

A case will be described in which the body belt 7 to which the supporter belt 6 having a width of 100 mm is attached is coupled to a harness-type safety belt using the coupling tool 3d.
By inserting the harness belt 1 so as to be in contact with the surface of the one end side 311d of the locking body 31d and the back surface of the central side 313d located between the two insertion holes and the surface of the other end side 314d, One locking body 31d is locked to the harness belt 1, and the body belt 7 fitted with the supporter belt 6 having a width of 100 mm is disposed perpendicularly to the harness belt 1 and immediately above the locking body 31d, and has a width of 100 mm. The body belt 7 to which the supporter belt 6 is attached is sandwiched between the connector 32d and the harness belt 1, and the other locking body 31d is located at the center between the surface of one end side 314d and the two insertion holes 312d. By inserting the back surface of the side 313d and the surface of the other end side 311d so as to contact the harness belt 1, the harness type safety belt and the body belt are combined.
