Description

[Technical Field]

[0001] The present invention relates to a harness jacket, and more particularly to a jacket that a worker wears over a harness with a lanyard attached. [Background technology]

[0002] To ensure worker safety at work sites such as civil engineering and construction sites, workers are required to wear a harness (safety belt), which is connected to a lifeline and secured to a structure such as an anchor. During cold or hot weather, workers must wear a harness, attach a lanyard (rope), and then put on a jacket over the harness. Patent Documents 1 and 2 propose a harness jacket with a slide fastener extending downward from the collar on the back, allowing workers to don a harness, attach the lanyard, and then remove the jacket. Patent Document 3 proposes a jacket with an opening at the upper back and a snap fastener at the top. [Prior art documents] [Patent documents]

[0004] However, the jackets in Patent Documents 1 to 3 have an opening on the back, making it difficult to close the slide fastener or snap buttons when the lanyard is connected to the harness, and there is no way to check whether they are closed, so ultimately it is necessary to ask someone else to check. In particular, if the slide fastener or snap buttons are forgotten to be closed, there is a risk of being caught in machinery or the rope becoming tangled, resulting in a dangerous situation.

[0005] In order to solve the above-mentioned conventional problems, the present invention provides a highly safe harness jacket that can be easily put on and taken off with a lanyard attached to the harness, and does not require checking whether the back is open or closed. [Means for solving the problem]

[0006] One embodiment of the present invention is a harness jacket that is worn over a harness with a lanyard attached to the harness, and the back of the jacket includes an opening that remains open in the length direction from at least the position of the lanyard fastener to the upper part of both shoulders. There is no means for closing the opening above the opening. The present invention relates to a harness top characterized by the above. [Effects of the Invention]

[0007] The harness top of the present invention is a harness top that is worn over a harness with a lanyard attached to the harness, and the back of the top includes an opening that remains open in the lengthwise direction from at least the position of the lanyard fastener to the upper part of both shoulders, making it easy to put on and take off with the lanyard attached to the harness, and eliminating the need to check whether the back is open or closed, thereby providing a highly safe harness top.

[0009] The present invention provides a harness jacket worn over a harness with a lanyard attached to the harness. The back portion of the rear fabric of the jacket includes an opening that remains open in the body length direction, at least from the position of the lanyard attachment to the upper shoulders. This allows for easy donning and doffing of the harness with the lanyard attached, and eliminates the need to check whether the back portion is open, resulting in a highly safe harness jacket. Furthermore, the open opening prevents interference between the lanyard and the jacket, and does not impede various lanyard movements. For example, even if the lanyard approaches close to the neck, the lanyard and the jacket will not come into contact or become entangled.

[0010] The top is preferably a jacket worn as workwear in hot weather, with a fan to let outside air into the garment, or made of workwear fabric, jacket fabric, windproof or waterproof fabric worn in cold weather. The top may be sleeveless (vest), or may have long sleeves, three-quarter sleeves, or short sleeves.

[0011] The opening in the back preferably has a width that widens toward the top, but any shape is acceptable as long as it does not interfere with the lanyard and the jacket, does not hinder various lanyard movements, and does not cause the lanyard and the jacket to come into contact with or become entangled even when the lanyard touches the neck or shoulder. Specific shapes will be described later.

[0012] It is preferable that there be no means for closing the opening above the opening. This prevents interference between the lanyard and the jacket, and does not hinder various lanyard movements. For example, even if the lanyard comes into contact with the neck or shoulder, the lanyard and the jacket will not come into contact or become entangled, ensuring safety. If there is an opening / closing device such as a slide fastener or snap button above the opening to close the opening, the opening / closing device may come off when the lanyard comes into contact with the neck or shoulder, and the wearer will not realize that it has come off, creating a dangerous situation.

[0013] The lowest point of the opening, when the upper ends of the shoulders (reference numerals 5a and 5b in Figure 1) are taken as the upper ends and the bottom end of the hem as the lower end, is preferably up to 70%, more preferably up to 40%, and even more preferably up to 30% of the distance between the upper and lower ends in the body length direction, measured from the upper ends of the shoulders. If the opening is up to 70% of the distance measured from the upper ends of the shoulders, it will not be lower than the top of the wearer's pelvis, preventing the edge of the opening from lifting up even when the wearer bends forward. If the opening is up to 40%, it will be located above the lower torso, preventing the edge from lifting up even when the wearer twists their torso. If the opening is up to 30%, it will be located near the shoulder blades, preventing it from interfering with the connection between the harness and lanyard. The uppermost point of the opening is up to the upper shoulders, not in contact with the lanyard and preventing it from interfering with various lanyard movements. However, since these values ​​are expected to vary slightly depending on the design of the jacket, the lowest point of the opening is limited to a position that does not interfere with the connection or functionality of the lanyard and harness.

[0014] The acromion line connecting the upper and lower shoulders is preferably sewn three-dimensionally with a bulge. This prevents wrinkles and sagging. To achieve this three-dimensional sewing, for example, the upper seam line of the back body fabric of the jacket is made a line that slopes gently downward from the neck side of the acromion line toward the upper arm side, while the seam line of the front body fabric from the neck side to the upper arm side is made a straight line, so that the acromion line is sewn three-dimensionally with a bulge. As a result, the back body fabric around the opening is pulled from the acromion line toward the upper arm side (from the center of the body to the outside), preventing wrinkles and sagging in the back body. Note that the acromion line is not essential; shoulder fabric parts may be made to cover both upper and lower shoulders in a belt-like manner.

[0015] The fabric around at least the opening of the upper garment may be a stretchable fabric. If a stretchable fabric is used and sewn to a size smaller than the wearer's physique, the opening will be stretched when worn, so that it will fit snugly against the wearer, preventing wrinkles and bulges, and improving safety. The stretchable fabric may be a one-way fabric containing elastic fiber yarn, a two-way fabric, or a stretchable fabric containing conjugate yarn.

[0016] The jacket of the present invention can be put on and taken off with the lanyard still attached to the harness. The fact that the jacket can be put on and taken off by the wearer alone is important in terms of improving work efficiency.

[0017] The upper garment may be provided with a fan for blowing air into the upper garment and an exhaust port for discharging the air. Upper garments equipped with a fan are commonly used as workwear during hot seasons.

[0018] The exhaust port is preferably a gap formed by a spacer. This spacer is preferably fixed to the backside of at least one of the front body panels near the top end of a slide fastener that can be opened and closed in the lengthwise direction of the front body panel. Without the spacer, when a heavy object that blows air into the upper garment, such as a fan, battery, or tool, is attached to the upper garment, it would be pulled by the fabric and crush the opening at the top end of the slide fastener, making it difficult to exhaust air. However, the spacer ensures that an air flow path is always maintained.

[0019] The upper garment fabric may contain antistatic fibers (antistatic fibers), which can prevent static electricity from occurring, preventing fires and static shocks.

[0020] The harness worn under the outer garment of the present invention is preferably a fall arrest harness. Fall arrest harnesses come in two types: full harness and waist belt. Both types are available in single-line and U-line suspension equipment, as well as dedicated single-line suspension (fall protection) equipment, and any of these can be used.

[0021] The following description will be given with reference to the drawings, in which the same reference numerals indicate the same elements. FIG. 1 is a schematic back view of a harness top 1 according to one embodiment of the present invention. This top 1 is worn over a harness with a lanyard attached to the harness. The back body 2 of the harness top 1 has an opening 3, and a harness lanyard fastener 4 is located below the opening 3. The opening 3 does not include the lanyard fastener 4 and does not have fabric extending to the area between the upper shoulders 5a and 5b. There are no slide fasteners to close the opening 3, nor snap buttons or the like to partially connect both sides of the opening. The shoulders 7a and 7b, which connect the upper shoulders 5a and 5b and the lower shoulders 6a and 6b, form the apparent acromions and define the top edge of the top 1. The acromion stitching lines 8a and 8b are located lower on the back than the apparent acromions 7a and 7b (top edge lines). This design improves the load concentration on the acromion lines 7a, 7b (top line) when heavy items such as fans, batteries, or tools are attached to the top. The fabric pulls on the acromion lines, which can easily damage the fabric if a seam is present in this area. The back body 2 of the harness top 1 has fans 7a, 7b on the left and right sides of the lower bottom section, which blow air into the top, and a battery storage compartment 11 in the center. The battery is located in the center of the lower back. If there are two fans, they are preferably positioned between the fans, as the weight of the battery reduces the gap between the opening edge (particularly the acromion line connecting the upper shoulders 5a, 5b and the lower shoulders 6a, 6b) and the wearer. Furthermore, it is preferable to provide a reinforcing member at the opening edge that is less stretchy than the body fabric. In the case of a jacket that uses a fan to draw outside air into the garment, the reinforcing member reduces the gap between the opening edge and the wearer due to increased internal pressure. 9 is a long-sleeved shirt (inner shirt) worn under a harness.

[0022] FIG. 2 is a schematic front view of a harness top 1 according to one embodiment of the present invention. The center of this top 1 features a slide fastener 13 that can be opened and closed along the body length, allowing the top to be put on and taken off by opening it. The fastening mechanism may be a snap fastener or a regular button. The neck of the front body 12 may be a round neck or a V-neck. The neck of the front body passes over both upper shoulders 5a and 5b and connects to the opening edge of the back body. Air blown into the top 1 from fans 10a and 10b primarily passes through spacers 20a and 20b and is exhausted from the front of the neck. This allows the air to blow from the neck to the face and head, effectively cooling the body. Cooling this area is particularly effective in the neck, where blood vessels are located close to the skin.

[0023] 3 is a schematic rear view showing a state in which a lanyard consisting of a carabiner 16 and the like is connected to the lanyard fastener 4 of a harness 14 via a D-ring 15, and the harness top 1 is worn over the lanyard fastener 4 in one embodiment of the present invention. As shown in FIG. 3, the attachment position of the lanyard fastener 4 is located at the bottom of the opening 3. FIG. 4 is a schematic front view of FIG.

[0024] Figure 5 is a schematic paper pattern diagram of the main parts of a harness top 1 according to one embodiment of the present invention. In this harness top 1, a seam line 17 along the acromion line, located at the top of the back body 2, is a gently sloping line that slopes downward from the neck toward the upper arm. A seam line 18 along the acromion line of the front body 12 is a straight line or a slightly curved line. By sewing along the seam lines 17 and 18, the acromion line 19 is sewn in a bulging three-dimensional shape. As a result, the back body fabric around the opening is pulled from the neck toward the upper arm (from the center of the body to the outside) at the acromion line 19, preventing wrinkles and sagging.

[0025] 6 is a schematic rear view of a harness top according to an embodiment of the present invention. As shown in FIG. 6, the bottom of the opening 3 is placed below the wearer's shoulder blades, and the lanyard fastener does not interfere with the fabric. The bottom shape of the opening 3 may be rectangular 23, elliptical arc 24, or other shapes such as round, U-shaped, or triangular.

[0026] FIG. 7A is a schematic diagram showing the area where fabric may be present on the right half of the back body. Point X corresponds to the right shoulder upper part 5a. Point C is the intersection of the center line of the body and the opening. The lowest point of the opening, with both shoulder upper parts (reference numerals 5a and 5b in FIG. 1) as the upper end and the hem end as the lower end, is preferably up to 70% of the distance measured from the upper ends of both shoulders, more preferably up to 40%, and even more preferably up to 30%. Point Cu is the upper limit of the lower end of the opening, and is 30% of the distance measured from both shoulder upper parts 5a and 5b to the hem end. Point Cd is the lower limit of the lower end of the opening, and is 70% of the distance measured from both shoulder upper parts 5a and 5b to the hem end. Point C can be set arbitrarily between points Cu and Cd. When the distance between points X and C is taken as the radius and a circular arc with center point Q on the opposite side of opening 3 connects points X and C, if the fabric is positioned within the shaded area α, the fabric around the opening will not interfere with the harness. Figures 7B-7D show examples of the shape of the opening in a harness top connecting points X and C. As long as the line is within area α and passes through points X and C, and does not cause the edge of the fabric to droop, either a straight line or a curve can be selected. Figure 7B shows an example where points X and C are connected by a straight line, Figure 7C shows an example where points X and C are connected by an arc, and Figure 7D shows an example where points X and C are connected by a smooth curve.

[0027] FIG. 8A is another schematic diagram showing the area where fabric may be present on the right half of the back body. A relay point Y is placed at an arbitrary position within region α in FIG. 7A. When arcs are drawn between points X and Y and between Y and C using the same procedure as in FIG. 7A, if the fabric is located within the shaded region β, the fabric around the opening will not interfere with the harness. Preferably, arcs are drawn with the line segments connecting points X and Y and between Y and C as their axes, and the opening edge is located in the region passing through regions γ1 and γ2 between the two arcs. This prevents the fabric around the opening from interfering with the harness and effectively prevents fabric sagging. More preferably, relay point Y is placed within region α, excluding the square region δ 5 cm below and to the right of point C. This effectively prevents the fabric around point C from sagging.

[0028] Figures 8B-8D show examples of more preferable shapes of the opening of a harness jacket when a relay point Y is provided. Figure 8B shows an example in which points X and Y are connected by straight lines, and points Y and C are connected by straight lines, with the opening width increasing upward. Figure 8C shows an example in which points X and Y are connected by a straight line, and points Y and C are connected by an upward arc, with the opening width remaining the same. Figure 8D shows an example in which a straight line passing through point X and a curved line passing through point C are connected by a curved line passing through point Y, with the opening width increasing downward. By providing relay point Y in this way, the width of the bottom of the opening, where the lanyard fastener is attached, is increased, further reducing interference between the fabric and the harness.

[0029] Figures 9A-C show preferred embodiments of the shape of the opening of a harness jacket of the present invention. Figures 9A and 9B show examples in which points X and Y, and points Y and C, are connected by curves with one inflection point each, Z1 and Z2. Figure 9C shows an example in which points X and Y are connected by a curve with one inflection point Z1, and points Y and C are connected by a curve with no inflection points. By smoothly connecting points X and Y, and points Y and C, respectively, with curves with one or fewer inflection points, interference between the fabric and the harness or lanyard fastener, as well as the risk of fabric sagging, can be further reduced. While specific opening shapes are described in Figures 7 to 9, these shapes are not limiting and any shape is acceptable as long as the fabric around the opening does not sag.

[0030] 10 is a schematic explanatory diagram showing a battery storage section 11 in one embodiment of the present invention. This battery storage section 11 is composed of a pocket section 27 formed on a pocket auxiliary fabric 26. A battery 29 is stored in the pocket section 27, and a lid is secured with a hook-and-loop fastener 28. The battery 29 and fans 10a and 10b are connected by electric wires 31a and 31b. 30a and 30b are fasteners for the electric wires 31a and 31b. Only the top and bottom ends of the pocket auxiliary fabric 26 are sewn horizontally to the back of the fabric of the back body 2. The middle part between the pocket auxiliary fabric 26 and the fabric of the back body 2 is free, and the fabric of the back body 2 expands due to the air blown from the fans 10a and 10b. This allows the air blown from the fans 10a and 10b to cool the back.

[0031] 11 is a schematic perspective view of a spacer body 32 according to one embodiment of the present invention. The spacer body 32 is made of resin such as polypropylene, and is a cylindrical body with a roughly triangular cross section, an internal reinforcing wall, and numerous holes. The cross section is larger at the top and smaller at the bottom. The top measures approximately 40 mm wide (portion 33 that comes into contact with the front body fabric) and 25 mm high (portion 34 that ensures ventilation) when viewed from the cross section. The bottom measures approximately 40 mm wide and 25 mm high, for an overall length of approximately 100 mm. [Example]

[0032] The present invention will be explained in more detail below using examples, but it should be understood that the present invention is not limited to the following examples.

[0033] Example 1 (1) Threads of the upper garment fabric The yarn material is polyester, with a warp thread of 84T (35 filaments) and a weft thread of 167T (67 filaments). (2) Fabric of the top The fabric is woven, with a twill weave, warp density of 145 threads / inch, weft density of 108 threads / inch, and weight of 110g / m 2 is. The above fabric was used to create the jacket (men's size L) shown in Figures 1 and 2. When left at rest, the length (length from a horizontal line drawn between both shoulders 5a and 5b in Figure 1 to the hem) was 660 mm, the width (circumference) was 1200 mm, and the size of the opening in the back was 190 mm wide at the top of both shoulders (a horizontal line drawn between both shoulders 5a and 5b in Figure 1), 100 mm wide above the bottom curve, 235 mm high, and weighed 330 g (but without battery or fan). Next, a worker at height was fitted with the harness shown in Figure 3-4, and a lanyard was connected to it, and a test was conducted to see if the jacket could be put on and taken off smoothly.Next, when the worker worked at height while wearing the jacket, the opening meant that the lanyard and the jacket did not interfere with each other, and the various movements of the lanyard were not hindered, and even when the lanyard came close to the neck, the lanyard and the jacket did not come into contact or become entangled.

[0034] Example 2 (1) Threads of the upper garment fabric The yarn material is polyester, with a warp thread of 84T (72 filaments) and a weft thread of 167T (48 filaments). (2) Fabric of the top The fabric is woven, with a twill weave, warp density of 145 threads / inch, weft density of 108 threads / inch, and weight of 145g / m 2 is. As in Example 1, this jacket was also fitted with a harness, a lanyard was attached, and a test was carried out to see if the jacket could be put on and taken off. The jacket was able to be put on and taken off smoothly. Next, when the subject worked at height while wearing the jacket, the openings prevented the lanyard from interfering with the jacket, did not hinder various lanyard movements, and even when the lanyard approached close to the neck, the lanyard and the jacket did not come into contact or become entangled. In addition, in the case of the fan-equipped garment, most of the air blown by the fan flowed out of the garment through the spacer. [Industrial Applicability]

[0035] The harness jacket of the present invention is suitable as a jacket to be worn over a fall arrest harness such as a full harness type or a waist belt type. [Explanation of symbols]
