JP7347948B2 - Rainwear for work - Google Patents

Description

The present invention relates to work rainwear.

When working in high places such as in the construction industry, when working at a height of 2 meters or more, a work floor should be provided, and the edges and openings of the work floor should be provided with fences, handrails, covers, etc. It is common to prevent workers from falling.

On the other hand, when such measures are difficult, it is common to use fall arrest equipment. There are two types of fall arrest devices: torso belt type and full harness type. A full-harness type fall arrest device consists of a belt that holds multiple parts of the body, such as the shoulders, thighs, and chest. When a wearer of a full-harness type fall arrest device falls from a high place, the risk of the user's body slipping out of the safety belt or excessive pressure on the chest and abdomen is reduced.

In addition, when working outdoors or in bad weather such as rain, wear water-repellent and waterproof rainwear. Rainwear includes raincoats, rain suits, and ponchos. Rainwear is used not only for outdoor work in rainy weather, but also for commuting to work or school in rainy weather, cycling, mountain climbing, golfing, etc. in rainy weather.

This kind of rainwear is known to have an opening (ventilation) in the back of the rainwear in order to prevent heat and moisture from building up inside the rainwear due to water-repellent and waterproof treatment. For example, see Patent Document 1).

Furthermore, clothing is known that has an opening for connecting a lifeline (lanyard) to a full harness-type fall arresting device worn by a worker (for example, see Patent Document 2).

Patent Document 1 discloses a structure in which the yoke has an opening in at least a part of its lower side by partially joining the yoke and the lower body in a jacket whose torso is composed of a yoke and a lower body. ing. This actively enhances the ventilation effect and provides a pleasant cooling sensation when worn in hot and humid conditions.

Patent Document 2 discloses that work clothes that include at least a front body and a back body have an opening in the widthwise center of the back body through which a locking tool of a safety device worn by a worker can be inserted. A configuration is disclosed in which the holes are beveled. This allows workers to wear safety equipment and cold-weather work clothes.

Japanese Unexamined Patent Publication No. 57-042907 Utility model registration No. 3197200

However, Patent Document 1 does not consider the case where a worker wears a fall prevention device, and there is no description of suppressing the movement of the lanyard. Therefore, in the configuration of Patent Document 1, even if a lanyard is passed through an opening (ventilation) in the back body, the opening will be rolled up as the lanyard moves, and rainwater will infiltrate into the inside of the jacket. There is a problem.

Furthermore, Patent Document 2 does not include any description that takes into consideration the intrusion of rainwater from the opening. Therefore, the configuration of Patent Document 1 has a problem in that rainwater infiltrates into the clothing through the opening.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide rainwear for work that prevents rainwater from entering the rainwear through an opening for passing a lanyard through a fall prevention device worn by a worker.

In order to achieve the above object, the rainwear for work of the present invention has an opening provided in the rear body for passing a lanyard through a fall prevention device worn by a worker, and an opening provided below the opening. a suppressing portion for suppressing the movement of the lanyard, the opening portion extending downwardly in a state in which an inner opening piece and an outer opening piece disposed outside the inner opening piece overlap. It is characterized by being formed facing towards the other side.

The work rainwear of the present invention configured in this way can prevent rainwater from entering the inside through the opening for passing the lanyard through the fall prevention device worn by the worker.

EMBODIMENT OF THE INVENTION Hereinafter, the embodiment which implement|achieves the rainwear for work by this invention is described based on Example 1 and Example 2 shown in drawing.

In Example 1, a work rainwear to be worn by a worker wearing a full harness type fall arrest device will be described.

[Composition of work rainwear]
Hereinafter, the structure of the working rainwear of Example 1 will be explained based on FIGS. 1 to 6. In addition, below, the up-down direction shall indicate the length direction.

As shown in FIG. 1, the work rainwear 30 is worn by a worker M with a full harness-type fall arresting device (harness) 10 mounted on top of the clothing 2. A lifeline (lanyard) 20 is connected to the harness 10.

(Harness)
The harness 10 is a full-harness type fall arresting device, and as shown in FIGS. 2 and 3, it includes a belt 11 that supports the shoulders, waist, and thighs of the worker M, and a support body 12 that supports the belt 11. , and a ring member (D ring) 13 attached to the support body 12.

(Lanyard)
As shown in FIG. 3, the lanyard 20 includes a rope 21, a carabiner 22 attached to one end of the rope 21 via a shock absorber 23, and a carabiner 22 attached to the other end of the rope 21. A hook 24 to be attached is provided.

The carabiner 22 can be connected to the D ring 13. The hook 24 can be hung on the handrail 1, for example. Note that the hook 24 can be hooked at a higher position than the D ring 13 to shorten the falling distance in the event of a fall, and to suppress the impact load applied when preventing the fall.

(Front body of work rainwear)
The work rainwear 30 is made of waterproof fabric. The work rainwear 30 can be made of Gore-Tex (registered trademark) fabric, for example. The working rainwear 30 can be long enough to cover the buttocks of the worker M. As shown in FIG. 2, the front body 31 of the work rainwear 30 includes an opening 33, a transparent part 34 attached to the opening 33, and a ring part 32 to which the hook 24 of the lanyard 20 can be attached. Be prepared.

The opening 33 is provided near the right chest of the worker M. The opening 33 is formed, for example, into a vertically long rectangle of about 7 [cm] x 10 [cm].

The transparent portion 34 is made of waterproof transparent fabric. The transparent portion 34 can be made of, for example, a transparent fabric made of polyurethane. The transparent portion 34 is formed in a size large enough to cover the opening 33.

The ring portion 32 is adapted to allow the hook 24 of the lanyard 20 to be hung thereon when the lanyard 20 is not in use.

(Back part of rainwear for work)
As shown in FIG. 4, the back body 41 of the working rainwear 30 is integrally formed by sewing together a rainwear upper part 42, a rainwear lower part 43, and a sleeve part 44.

The rainwear upper part 42 and the rainwear lower part 43 are formed so as to partially overlap in the vertical direction (length direction). The rainwear upper part 42 is placed outside the rainwear lower part 43 to form this overlap.

The distance from the lower end 42a of the rainwear upper part 42 to the upper end 43a of the rainwear lower part 43 is, for example, about 5 to 15 cm. That is, the rainwear upper part 42 and the rainwear lower part 43 are formed so as to overlap by, for example, about 5 to 15 cm.

The rainwear upper part 42 and the rainwear lower part 43 are sewn together on the outside in the width direction of the work rainwear 30. That is, the rainwear upper part 42 and the rainwear lower part 43 form a seam part 43b on the outside in the width direction of the work rainwear 30. In other words, the rainwear upper part 42 and the rainwear lower part 43 have no seam portion 43b formed in the center in the width direction of the work rainwear 30.

<Opening>
As shown in FIG. 5, the central portion where the stitched portion 43b is not formed forms an opening 48. The opening 48 is an opening that communicates from the inside of the work rainwear 30 to the outside, and is formed facing downward. The opening 48 can have a size of, for example, about 14 to 17 cm in the width direction of the work rainwear 30.

The portion of the rainwear upper part 42 that forms the opening 48 constitutes an outer opening piece 42A. The portion of the rainwear lower part 43 that forms the opening 48 constitutes an inner opening piece 43A. That is, the opening 48 is formed so as to face downward, with the inner opening piece 43A and the outer opening piece 42A disposed outside the inner opening piece 43A overlapping each other.

A folded portion 43c, in which the end of the inner opening piece 43A is folded back outward, is formed at the upper end of the inner opening piece 43A. The folded portion 43c is formed by, for example, folding the inner opening piece 43A outward by approximately 1 cm.

A hook-and-loop fastener 46 as a fastening member for fastening the inner opening piece 43A and the outer opening piece 42A is attached to the front surface of the inner opening piece 43A and the back surface of the outer opening piece 42A. When worker M is not wearing the harness 10 or has not connected the lanyard 20, the inner opening piece 43A and the outer opening piece 42A are fastened together using the hook and loop fastener 46 to prevent rainwater and wind from entering. can be prevented.

<Loop section>
Below the opening 48, as shown in FIGS. 4 and 5, a loop portion 45 is provided as a suppressing portion that suppresses movement of the lanyard 20. The loop portion 45 can be attached at a position approximately 2 to 5 cm below the lower end of the opening 48, for example. The loop portion 45 is made of waterproof fabric and is formed into a band shape, for example, about 2 cm wide and 14 to 19 cm long.

Both ends of the loop part 45 are sewn to the rainwear lower part 43. Sewn portions 45b are formed at both ends of the loop portion 45. The loop part 45 constitutes an annular loop part together with the rainwear lower part 43.

(inner)
As shown in FIG. 6, the working rainwear 30 may have an inner layer 50 that can be attached to and removed from the working rainwear 30.

An opening 53 is formed in the front body 51 of the innerwear 50 near the right chest of the worker M so as to correspond to the opening 33 of the work rainwear 30. The opening 53 of the inner 50 is formed into a vertically long rectangle of, for example, about 8 [cm] x 11 [cm]. The opening 53 of the innerwear 50 is formed to be slightly larger than the opening 33 of the work rainwear 30.

An opening 55 for connecting the lanyard 20 to the harness 10 worn by the worker M is formed in the rear body of the innerwear 50.

[Effects of work rainwear]
Hereinafter, the operation of the working rainwear 30 of the first embodiment will be explained based on FIGS. 7 to 9.

By the way, it is recommended that the hook 24 of the harness 10 be hooked at a position as high as possible, at least at a position higher than the D ring 13, in order to shorten the falling distance in the event of a fall and reduce the impact load applied to the wearer when preventing a fall. has been done. If the hook 24 is hooked at a position lower than the D ring 13, the falling distance in the event of a fall will become longer, and the impact load applied when preventing the fall will increase. However, if the hook 24 of the harness 10 is hooked at a high position, the opening 48 may be rolled up by the lanyard 20, and there is a risk that rainwater may enter through the opening.

The work rainwear 30 of the first embodiment has an opening 48 provided in the back body 41 for passing the lanyard 20 through a fall prevention device (harness 10) worn by the worker M, and an opening 48 in the opening 48. The opening 48 includes an inner opening piece 43A and an outer opening disposed outside the inner opening piece 43A. It is formed with the pieces 42A overlapping each other and facing downward (FIG. 3).

Thereby, as shown in FIG. 7, the posture of the lanyard 20 near the connecting portion can be directed downward. Therefore, the opening 48 can be prevented from being rolled up due to movement of the lanyard 20. As a result, rainwater can be prevented from entering through the opening 48 when the worker M is working, especially when bending or squatting.

On the other hand, in the case of the work rainwear 930 that does not include the restraining part (loop part 45), the posture of the connecting part of the lanyard 20 is oriented upward, as shown in FIG. Therefore, the opening 48 ends up being rolled up due to the movement of the lanyard 20. As a result, rainwater enters through the opening 48 when the worker M is working, especially when bending or squatting.

Furthermore, the opening 48 can be directed downward while the worker M is wearing the work rainwear 30. Therefore, rainwater can be prevented from entering through the opening 48 when the worker M is working. That is, since the end of the inner opening piece 43A of the opening 48 is higher than the end of the outer opening piece 42A, rainwater flows over the outer opening piece 42A and flows inside the work rainwear 30. Rainwater will not enter. However, since the opening 48 allows air to flow in and out, heat and moisture trapped inside the work rainwear 30 can be discharged.

In the work rainwear 30 of Example 1, the restraining part is an annular loop part 45 provided below the opening part 48 (FIG. 5).

Thereby, the posture of the lanyard 20 near the connecting portion can be directed downward by the loop portion 45. Therefore, with a simple configuration, it is possible to prevent rainwater from entering through the opening 48 when the worker M is working.

In the work rainwear 30 of Example 1, the upper end of the inner opening piece 43A is provided with a folded part 43c in which the fabric is folded back (FIG. 5).

Thereby, even if rainwater enters through the opening 48, it is possible to prevent the rainwater from entering the inside of the work rainwear 30.

In the work rainwear 30 of Example 1, a transparent portion 34 is provided on the chest of the front body 31 (FIG. 2).

Thereby, as shown in FIG. 9, it is possible to check what the worker M is wearing through the transparent part 34. Therefore, the site manager, etc. can check whether the worker M is wearing the harness 10 correctly while wearing the work rainwear 30, and the worker himself can check. .

The work rainwear of Example 2 differs from the work rainwear of Example 1 in that the structure of the suppressing part is different.

[Composition of work rainwear]
FIG. 10 is a rear view showing the work rainwear of Example 2. Hereinafter, the structure of the working rainwear of Example 2 will be explained based on FIG. 10. Note that parts that are the same or equivalent to those described in the above embodiments will be described using the same terms or the same symbols.

In the work rainwear 130 of Example 2, as shown in FIG. 10, an opening 148 is formed in the center where the stitched portion 43b is not formed. The opening 148 is an opening that communicates from the inside of the work rainwear 130 to the outside, and is formed downward. The opening 148 can have a size of, for example, about 14 to 17 cm in the width direction of the work rainwear 130.

The portion of the rainwear upper part 42 that forms the opening 148 constitutes an outer opening piece 142A. The portion of the rainwear lower part 43 that forms the opening 148 constitutes an inner opening piece 143A.

The outer opening piece 142A protrudes downward from the lower end 42a of the rainwear upper part 142 by, for example, about 5 cm, and forms a tongue portion. Both ends of the outer opening piece (tongue) 142A in the width direction of the work rainwear 130 are sewn to the rainwear lower part 43. Sewing portions 142b are formed on both sides of the outer opening piece (tongue portion) 142A.

The opening 148 is formed so as to face downward, with the inner opening piece 143A and the outer opening piece 142A disposed outside the inner opening piece 143A overlapping each other.

[Effects of work rainwear]
Next, the operation of the working rainwear 130 of the second embodiment will be explained. In the work rainwear 130 of Example 2, the restraining part is a tongue part from which the outer opening piece 142A projects downward, and the sides of the tongue part are sewn together (FIG. 9).

Thereby, the posture of the lanyard 20 in the vicinity of the connecting portion can be directed downward by the tongue portion. Therefore, with a simple configuration, it is possible to prevent rainwater from entering through the opening 148 when the worker M is working.

Note that the other configurations and effects are substantially the same as those of the above embodiment, so explanations will be omitted.

The working rainwear of the present invention has been described above based on the first and second embodiments. However, the specific configuration is not limited to these examples, and changes in design, combinations of examples, Additions, etc. are permitted.

In Examples 1 and 2, the transparent portion 34 is provided near the right chest of the worker M. However, the transparent portion may be provided near the left chest of the worker, or may be provided near both the left and right breasts _.

In Example 1 and Example 2, examples were shown in which the work rainwear 30, 130 did not have a hood. However, the work rainwear may be hooded. In this case, for example, when the hood is not being worn, the suppressing portion directs the lanyard near the connecting portion downward, so that excessive interference between the hood and the lanyard 20 can be prevented.

In Example 1 and Example 2, an example was shown in which the fastening member for fastening the inner opening piece 43A and the outer opening piece 42A is the hook-and-loop fastener 46. However, the fastening member may be a button, a fastener, or the like.

In Examples 1 and 2, examples were shown in which the opening 33 was formed into a vertically long rectangle. However, the opening may be a horizontally long rectangle or a circle.

In Examples 1 and 2, the loop portion 45 is made of waterproof fabric. However, the loop portion may be formed of an elastic body such as rubber. In this case, movement of the lanyard can be further suppressed.

In Examples 1 and 2, an example is shown in which the present invention is applied to work rainwear worn by a worker M wearing a full harness type fall arrest device. However, the present invention can also be applied to work rainwear that is worn by the worker M while wearing a torso belt type fall arresting device or a chest harness.

In Example 1 and Example 2, an example was shown in which the present invention is applied to work rainwear 30, 130 that is long enough to cover the buttocks of worker M. However, the present invention can also be applied to rainwear for work that has a length up to the worker's waist.

In Examples 1 and 2, an example was shown in which the present invention is applied to work rainwear in which the lanyard 20 is inserted into the opening 48 and connected to the D ring 13. However, the present invention can also be applied to work rainwear in which a lanyard connected to a fall arrest device is passed through the opening 48 in advance.
