Description

[Technical field]

[0001] The present invention relates to a coverall in which the top and pants are connected and which has an openable front part. [Background technology]

[0002] As is well known, coveralls are made up of a top and pants that are connected, and therefore prevent the intrusion of foreign objects into the clothing, allowing workers to work safely and hygienically, and are widely used as work clothes in industrial, agricultural, and other fields. In addition, coveralls are roomy between the wearer's body, allowing them to be worn loosely and relatively easy to move in, and because air is ventilated between the wearer's upper and lower body in response to the wearer's movements, they have excellent internal breathability and can be worn relatively comfortably.

[0003] However, in conventional coveralls, because the top and trousers are connected, the weight of not only the top but also the trousers is placed on the wearer's shoulders at the same time, which places a heavy burden on the shoulders and makes them prone to stiff shoulders.

[0004] Therefore, in the past, a belt was wrapped around the waist of the overalls so that the weight of the trousers was supported by the wearer's torso or waist (see, for example, paragraph "0013" in the following Patent Document 1). However, because this overalls simply involved wrapping a belt around the outside of the waist, it had the drawback of blocking airflow between the wearer's upper and lower body, significantly reducing internal breathability. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Registered Utility Model No. 3135570 Summary of the Invention [Problem to be solved by the invention]

[0006] To solve the above-mentioned problems of conventional coveralls, the present invention has been made, and it is an object of the present invention to provide a breathable coverall which puts less strain on the shoulders of the wearer and has excellent internal breathability between the top and trousers. [Means for solving the problem]

[0007] The present invention relates to a coverall in which a top and pants are connected and the top and pants have a front opening that can be opened and closed, a belt-shaped member that is wrapped around the back side of the torso of a wearer inside the trousers, the belt-shaped member having both ends fixed to the inside of the waist part of the trousers and a middle part that is separated from the waist part to form an air passage between the waist part and the belt-shaped member; and a flexible hanging part having an upper end attached to the middle part of the rear belt part and a lower end fixed to the inner surface of the trousers, When worn, the weight of the trousers is supported by the rear belt portion via the hanging portion.

[0008] In addition, the present invention is characterized in that the rear belt portion is provided with a length adjustment mechanism.

[0009] The present invention is also characterized in that at least the rear portion of the top is provided with a pleat portion formed by covering the bottom hem of the top over the outside of the waist portion of the trousers.

[0010] Furthermore, the present invention is characterized in that the front portion of the jacket and the front portion of the trousers are separated at the front opening.

[0011] The present invention is also characterized in that an attachment opening is provided in the upper garment to which a blower can be attached in a freely detachable manner, and the blower attached to the attachment opening supplies outside air into the upper garment and the trousers. Effect of the Invention

[0012] The breathable coveralls of the present invention are equipped with a rear belt portion that is wrapped around the back side of the wearer's torso on the inside of the trousers, and a hanging portion that connects this rear belt portion to the inside of the trousers.Therefore, when this breathable coveralls is worn, the weight of the trousers can be supported by the wearer's torso and waist via the rear belt portion and the hanging portion, significantly reducing the burden on the wearer's shoulders.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] "First embodiment" As shown in Figures 1 and 2, the breathable coveralls 10 of the first embodiment are composed of a top 1 for covering the upper body of a wearer, trousers 2 connected to the top 1 and for covering the lower body of the wearer, a rear belt portion 4 for wrapping around the back side of the wearer's torso inside the trousers 2, and a hanging portion 5 connecting the rear belt portion 4 to the inner surface of the trousers 2.

[0016] At the front of the top 1 and at the front of the trousers 2, respectively, there are formed front openings 31, 32 that continue from the top 1 to the upper part of the trousers 2, and these front openings 31, 32 are configured to be openable and closable by a known slide fastener. As opening and closing means for these front openings, in addition to slide fasteners, for example, clasps such as snaps, buttons, hooks, etc. can be appropriately used.

[0017] 3 and 4, the rear belt portion 4 is made of a flexible belt-shaped member, and both ends 41, 41 are sewn and fixed to the inside of the sides of the waist portion 21 of the trousers 2, while a middle portion 42 of the rear belt portion 4 is separated from the waist portion 21, and an air passage 6 is formed between the middle portion 42 and the rear inner surface of the waist portion 21. Note that the slide fastener of the front opening portion 32 of the trousers 2 is not shown in FIG. 3 and FIG. 12 described later.

[0018] The suspending part 5 is made of a flexible belt-like member and is located at the rear of the waist part 21 of the trousers 2, with its upper end 51 attached to the middle part 42 of the rear belt part 4 and its lower end 52 sewn and fixed to the inside surface of the trousers 2. As a result, when the breathable coveralls 10 is worn, the trousers 2 can be suspended by the suspending part 5, and the weight of the trousers 2 can be supported by the wearer's torso and waist via the rear belt part 4 and the suspending part 5.

[0019] In this embodiment, a ring is formed at the upper end 51 of the hanging part 5, and the rear belt part 4 is passed through the ring to attach the upper end 51 of the hanging part 5 to the rear belt part 4, but the present invention is not limited to this. For example, the upper end 51 of the hanging part 5 may be fixed to the rear belt part 4 by sewing or gluing. The hanging part 5 may also have a length adjustment mechanism such as a well-known movable can or ladder lock. If the hanging part 5 has a length adjustment mechanism, the length of the hanging part 5 can be appropriately adjusted to easily adjust the length of the pants. The hanging part 5 may also be made of a string-like member.

[0020] Thus, the breathable coveralls 10 of this embodiment are provided with the rear belt portion 4 that is wrapped around the back side of the wearer's torso on the inside of the trousers 2, and the hanging portion 5 that connects the rear belt portion 4 to the inside of the trousers 2, so that when a wearer M wears the breathable coveralls 10, as shown in Fig. 4, the weight of the trousers 2 can be supported by the wearer's torso and waist via the rear belt portion 4 and the hanging portion 5, and the weight of the trousers is not placed on the wearer's shoulders as in conventional products, and the burden on the shoulders of the wearer M can be significantly reduced. In the figure, the symbol B indicates the wearer's back, and the symbol H indicates the wearer's buttocks.

[0021] Furthermore, the breathable coveralls 10 of this embodiment suspend the pants 2 on the inside of the pants 2 by a hanging part 5 having the required length, so that there is sufficient space between the wearer M's body and the breathable coveralls 10 on the back side of the wearer M's torso, and the waist area of ​​the coveralls is not constricted from the outside by a belt as in conventional products, resulting in a relaxed fit.

[0022] Furthermore, in the breathable coveralls 10 of this embodiment, an air passage 6 is formed between the middle portion 42 of the rear belt portion 4 and the rear inner surface of the waist portion 21 of the pants 2, so that sufficient ventilation is achieved between the upper and lower body of the wearer M, as shown by the white arrow A in Figure 4, and the internal breathability is also excellent.

[0023] Furthermore, in the breathable coveralls 10 of this embodiment, the suspending parts 5 having a required length are flexible, so that, for example, as shown in Fig. 5, even if the rear parts of the top 1 and pants 2 are pulled upward as the wearer M bends forward, as shown by the outlined arrow U in Fig. 5, the flexible suspending parts 5 bend and the rear belt part 4 wrapped around the back side of the torso of the wearer M does not slide up, and the rear belt part 4 can be kept in an appropriate fixed position. Furthermore, the movement of the top 1 and pants 2 accompanying the movement of the wearer M is not restricted by the rear belt part 4, and they are very easy to move.

[0024] In addition, in the breathable coveralls 10 of this embodiment, the flexible suspending part 5 is bent, so that its lower end 52 can move not only upward but also left and right relative to the rear belt part 4, and further, because the rear belt part 4 is passed through a ring part formed on the upper end 51 of the suspending part 5, the upper end 51 of the suspending part 5 can also move left and right relative to the rear belt part 4. Therefore, not only when the wearer bends forward, but also when the wearer twists the upper body, for example, the rear belt part 4 can be kept in a proper fixed position, and the ease of movement can be further improved.

[0025] Second Embodiment Next, a breathable coveralls 20 of a second embodiment will be described with reference to Fig. 6. The breathable coveralls 20 are characterized in that the rear part of the upper garment 1 is provided with a total of two circular attachment openings 71, 71 penetrating the inside and outside of the upper garment 1, and each attachment opening 71 is configured to allow a known blower 7 to be detachably attached, while the rear belt part 4 and hanging part 5 are configured similarly to the coveralls 10 of the first embodiment described above.

[0026] The blower 7 is driven by a battery (not shown), and by operating the blower 7 attached to each mounting opening 71, outside air is supplied into the top 1. The outside air supplied into the top 1 is also supplied into the trousers 2 through the above-mentioned ventilation passage 6. In this way, according to the breathable coveralls 20 of the second embodiment, the blower 7 can smoothly supply outside air not only into the top 1 but also into the trousers 2 through the ventilation passage 6, so that the upper and lower bodies of the wearer can be efficiently air-cooled, for example, even when working outdoors in summer, and a more comfortable environment inside the clothing can be provided.

[0027] In the second embodiment of the breathable coveralls 20, an attachment opening 71 to which the blower 7 can be attached and detached is provided at the rear of the upper garment 1, but this attachment opening 71 may also be provided on the side of the upper garment.

[0028] "Third embodiment" Next, a breathable coveralls 30 of a third embodiment will be described with reference to Figures 7 to 12. The main features of the breathable coveralls 30 are that a length adjustment mechanism 43 is provided on the rear belt part 4 that is wrapped around the back side of the torso of the wearer, that a plurality of hanging parts 5 are provided on the inside of the trousers 2, that a pleated part 8 is provided on the rear part of the top 1 by placing the hem part 11 of the top 1 over the outside of the waist part 21 of the trousers 2, and that the front part of the top 1 and the front part of the trousers 2 are separated. The other configurations are the same as those of the coveralls 10 of the first embodiment described above.

[0029] As shown in Figures 7 and 8, the breathable coveralls 30 has the hem 11 of the top 1 covering the outside of the waist area 21 of the trousers 2 at the front and back, giving the top 1 and trousers 2 an appearance similar to separate work clothes, enhancing the design.

[0030] 9 and 10, a horizontal pleat 8 is formed at the rear of the top 1 by connecting the lower edge of the hem 11 of the top 1 and the upper edge of the waist part 21 of the trousers 2 with a flexible, strip-like connecting piece 81. This pleat 8 makes it easier for the top 1 to move relative to the trousers 2 when the wearer M, for example, bends or twists his or her upper body, further improving ease of movement.

[0031] Moreover, the connecting piece 81 forming the recess of the pleat portion 8 is provided with an oval opening 82, which allows ventilation to the outside. Instead of providing the opening 82 in this connecting piece 81, the connecting piece 81 itself may be made of a material with excellent breathability, such as mesh cloth. Also, the connecting piece 81 may not be provided with an opening, and may be made of a material that is almost non-breathable.

[0032] On the other hand, in the front part of the top 1 of the breathable coveralls 30, as shown in Fig. 11, the hem 11 of the top 1 and the waist 21 of the trousers 2 are separated, and no connecting piece 81 is present. That is, the front part of the top 1 and the front part of the trousers 2 are separated from each other at the front openings 31 and 32 of the breathable coveralls 30. This allows the front openings 31 of the top 1 and the front openings 32 of the trousers 2 to be opened larger, making it easier to put on and take off the breathable coveralls 30. Even when the front opening 31 of the top 1 is open, the top 1 and the trousers 2 can be made to look like separate work clothes in which they are separated.

[0033] 12, the breathable coveralls 30 are provided with a length adjustment mechanism 43 made of a known ladder lock at the middle portion 42 of the rear belt portion 4 that is wrapped around the back side of the wearer's torso. By manipulating this length adjustment mechanism 43 to appropriately adjust the length of the middle portion 42 of the rear belt portion 4, the width of the ventilation opening of the ventilation passage 6 formed between the rear belt portion 4 and the inner surface of the waist portion 21 of the trousers 2 can be adjusted.

[0034] Furthermore, the breathable coveralls 30 are provided with a plurality of (a total of two in this embodiment) hanging parts 5 on the inside of the rear part of the waist part 21 of the trousers 2. With this, when the breathable coveralls 30 are worn, the weight of the trousers 2 can be more stably supported by the torso and waist of the wearer via the rear belt part 4 and the hanging parts 5.

[0035] The breathable coveralls 30 are provided with a front belt portion 9 on the outside of the front part of the waist portion 21 of the trousers 2. The front belt portion 9 is made up of a pair of left and right flexible belt-shaped members 91, 91, the base end 92 of each belt-shaped member 91 being sewn and fixed to the outside of the side of the waist portion 21 of the trousers 2, and the tip side of each belt-shaped member 91 is provided with known male-female interlocking fasteners 93, 94. By connecting these fasteners 93, 94 to each other, the front belt portion 9 is wrapped around the front side of the wearer's torso. In the drawing, the reference numeral 95 indicates a pair of known belt loops on the left and right for passing the front belt portion 9 on the outside of the front part of the waist portion 21 of the trousers 2.

[0036] Thus, according to the breathable coveralls 30, the front belt part 9 is provided on the outside of the front part of the waist area 21 of the trousers 2, so that when the front opening part 31 of the top 1 is opened, the front belt part 9 can be exposed as shown in Fig. 11, and when the front opening part 31 of the top 1 is closed, the front belt part 9 can be concealed by the front part of the top 1 as shown in Fig. 7. This further enhances the design of the breathable coveralls 30 and widens the range of design options.

[0037] In this embodiment, primarily from the standpoint of design, known buttons are used as the opening and closing means for the front opening 31 of the top 1, and a known slide fastener is used as the opening and closing means for the front opening 32 of the trousers 2, but the present invention is not limited to this, and other opening and closing means can be used for each front opening.

[0038] Although the breathable coveralls of each embodiment have been described above, the present invention can be carried out in other embodiments.

[0039] For example, in the breathable coveralls 30 of the third embodiment, the pleats 8 are provided only at the back of the top 1, but the present invention is not limited to this. For example, in a breathable coveralls in which the top 1 and trousers 2 are connected around the entire periphery of their front and back, like the breathable coveralls 10 of the first embodiment, the pleats may be formed around the entire periphery of the hem of the top 1.

[0040] Furthermore, in the breathable coveralls of each embodiment, the top 1 is a long-sleeved top, but the present invention is not limited to this, and may be, for example, a short-sleeved top or a sleeveless top.

[0041] In the breathable coveralls 10 of the first embodiment, the top 1 and the trousers 2 may be made of different fabrics.

[0042] In addition, in the second embodiment of the breathable coveralls 20, a known blower 7 is configured to be removably attached to an attachment opening 71 provided at the rear of the upper garment 1, but the present invention is not limited to this, and the blower 7 may be configured to be removably attached to the upper garment 1 of the breathable coveralls 30 of the third embodiment.

[0043] In the breathable coveralls 30 of the third embodiment, the front belt portion 9 may be provided with a length adjustment mechanism such as a well-known movable can or ladder lock.

[0044] The present invention may be embodied in various other forms that include improvements, modifications, and variations based on the knowledge of a person skilled in the art, without departing from the spirit of the present invention. In addition, the present invention may be embodied in a form in which any of the invention-specifying matters is replaced with other techniques within the scope of the same action or effect, and an invention-specifying matter that is integrally configured may be composed of multiple members, or an invention-specifying matter that is composed of multiple members may be embodied in a form in which it is integrally configured.
