Description

TECHNICAL FIELD

This disclosure relates to a garment having an opening and closing portion on the front face.

BACKGROUND

Among garments having an opening and closing portion on the front face, garments are known in which a zipper is provided on the opening and closing portion, a slider of the zipper is held, and the slider is moved downward to open the opening and closing portion so that the garment is taken off.
On the other hand, there have been proposed a protective garment provided with an openable and closable front face opening and closing portion extending from a lower edge portion of a hood opening portion on the front face to a waist portion on the front face side (see Japanese Patent Publication No. 5560066); a garment having an inclination from a neck bottom portion to a waist portion and in which the right half is drawn rightward to move a slider portion downward (see Japanese Patent Publication No. 5409249); and a dust-free garment in which a zipper is provided to extend obliquely from a portion covering a neck portion to a portion covering a waist portion, and the garment is put on or taken off while a grip attached inside is held (see Japanese Patent Publication No. 3912060).
However, a protective garment as in JP '066 has the problem that when a slider of a zipper is held, and the zipper is moved downward during undressing, the slider portion cannot be held, and thus much time is taken for undressing so that the garment cannot be quickly taken off in the case of an emergency.
In addition, when a slider has a lock as in JP '249, there is the problem that since the slider is touched with an unclean hand, contaminants are likely stick to a body.
In addition, when with a grip attached inside, a zipper is opened to put on or take off a garment as in JP '060, there is the problem that since it is necessary to touch the inside of the opening portion, contaminants stuck on a hand are likely get to the inside of the garment.
Thus, it could be helpful to provide a garment that can be quickly taken off while contaminants stuck on a hand of a wearer are inhibited from getting to the inside of the garment and a body during undressing.

SUMMARY

We thus provide:
Our garment has an opening and closing portion for putting on and taking off the garment on the front body, in which a tab is placed at any position on each of the left and the right outside the opening and closing portion.
Preferably, an upper end portion of the tab is attached to an upper end of the opening and closing portion in conformity to the opening and closing portion, and a distance from the upper end of the opening and closing portion to a position at which the zipper is attached to the opening and closing portion is at least 1 cm.
Preferably, the zipper is a fastener to which a slider having no lock is attached.
Preferably, the tab is attached at each of any two or more positions on each of the left and the right of the upper end of the opening and closing portion and each of the right and the left of the opening and closing portion of a front body.
Preferably, the tab is placed on each of the left and the right with the opening and closing portion sandwiched therebetween, the left and right tabs has asymmetric in size, and the smaller tab is disposed inside the larger tab.
It is possible to obtain a garment that can be quickly taken off while contaminants stuck on a hand of a wearer are inhibited from sticking to the inside of the garment and a body from a zipper opening portion during undressing.

DETAILED DESCRIPTION

Our garment has an opening and closing portion for putting on and taking off the garment on the front body, in which a tab is placed at any position on each of the left and the right outside the opening and closing portion.
Preferably, the garment has an opening and closing portion for putting on and taking off the garment, the opening and closing portion passing through the center of a front body to reach any position on a waist portion.
The garment refers to an over all type garment in which an upper garment and a lower garment are integrally formed, or a garment having an opening and closing portion on the front face of the garment such as a jacket or a raincoat. Specific examples of the garment include antifouling protective garments and chemically protecting protective garments.
The fabric used for the garment may be any fabric such as a woven fabric, a knitted fabric or a non woven fabric, and synthetic fibers such as those of polyester and polyethylene are preferably used as a fiber material that forms such a fabric.
In addition, the upper end of the opening and closing portion refers to an upper end portion of a first tab attached to the upper end of the opening and closing portion.
Next, an example of the garment will be described in detail with reference to the drawings.
FIG. 1 is a front view showing one example of the garment. FIG. 2 is a perspective view showing the opening and closing portion. FIG. 3 is a perspective view showing the upper end of the opening and closing portion. FIG. 4 is a front view showing another example of the garment.
Our garment may be of a type in which an upper garment 1 and a lower garment 2 are integrally formed as shown in FIG. 1. The upper garment 1 has hood portion 3 and, as shown in FIG. 2, a first tab (large) 8 a and a first tab (small) 8 b, and a second tab (large) 9 a and a second tab (small) 9 b are sewn to an opening and closing portion 5 on the left and right. In addition, in FIG. 1, a substantially circular opening portion 30 that secures a field of view is formed on the front face of the hood portion 3. The lower garment 2 includes left and right leg portions 21 a and 21 b.
Preferably, the opening and closing portion 5 for putting on and taking off the garment extends from the position of the upper end at the center of the front body to the vicinity of the waist. Preferably, the opening and closing portion 5 of a front body 4 has the first tab (large) 8 a and the first tab (small) 8 b, and the second tab (large) 9 a and the second tab (small) 9 b on the left and right for making it possible to take off the garment, the first tab (large) 8 a and the first tab (small) 8 b are sewn on the left and right in conformity to the upper end 11 of the opening and closing portion, and the second tab (large) 9 a and the second tab (small) 9 b is sewn to the opening and closing portion 5 in a lower part as compared to the first tab (large) 8 a and the first tab (small) 8 b. By placing the tabs on the left and the right of the opening and closing portion 5, and drawing the tabs to the left and right in the order of the first tab and the second tab, the opening and closing portion 5 can be opened without holding a slider 7 of a zipper, and the garment can be quickly taken off while contaminants are inhibited from getting to a body because the slider is not touched with an unclean hand.
Preferably, the garment has an opening and closing portion for putting on and taking off the garment on the front body, in which the tab is placed at any position on each of the left and the right outside the opening and closing portion 5.
Preferably, a distance 11 a from the upper end 11 of the opening and closing portion to a zipper insertion is at least 1 cm. As shown in FIG. 3, an angle a of a line connecting the upper end 11 of the opening and closing portion and an upper end 7 a of the slider is less than 45° at the position of the upper end 7 a of the slider, and thus a force d for moving the slider 7 downward is greater than a force c for opening the tab to the left and the right so that a zipper 6 is easily opened. More preferably, the zipper is attached at such a position that the distance 11 a to the zipper insertion fastener is 1 cm or more and 3 cm or less.
When the distance 11 a to zipper insertion is less than 1 cm, the angle a is 45° or more, and thus the force c for opening the tab to the left and the right is greater than the force d for moving the slider downward so that when there is no difference in force c to open the tab, the force d to move the slider 7 downward is reduced, thus making it difficult to open the zipper. In addition, when the zipper 6 is placed at such a position that the distance 11 a is more than 3 cm, the upper end 11 of the opening and closing portion is opened, and therefore contaminants may enter from the opening and closing portion 5, resulting in sticking of contaminants to a body.
The zipper 6 is preferably a fastener, and the slider 7 of the fastener is preferably a slider having no lock. In a slider having a lock, it is necessary that the slider 7 be held by hand, lifted upward and moved downward so that contaminants stuck on a hand more likely stick to a body.
The position at which the second tab (large) 9 a and the second tab (small) 9 b are attached is preferably at a distance of 20 cm or more and 40 cm or less from the first tab (large) 8 a and the first tab (small) 8 b. Preferably, the distance is more preferably 25 cm or more and 35 cm or less. When the position of the second tabs 9 a and 9 b are at a distance of less than 20 cm, the distance from the second tab to the waist portion is long so that even when the second tab is expanded to the left and the right, the opening and closing portion 5 cannot be fully opened. In addition, when the positions of the second tab (large) 9 a and the second tab (small) 9 b are disposed at a distance of more than 40 cm below the first tab (large) 8 a and the first tab (small) 8 b, the zipper can be opened to the vicinity of the solar plexus, but the second tab is disposed below the solar plexus, and therefore even when the second tab (large) 9 a and the second tab (small) 9 b are expanded to the left and the right, the opening and closing portion 5 cannot be opened.
It is preferable that the first tab (large) 8 a and the first tab (small) 8 b have bilateral-asymmetric in size, and the second tab (large) 9 a and the second tab (small) 9 b have bilateral-asymmetric in size. More preferably, the smaller tabs, e.g., the first tab (small) 8 b and the second tab (small) 9 b, are disposed inside the larger tabs, e.g., the first tab (large) 8 a and the second tab (large) 9 a.
Generally, when a tab is placed, a double-sided tape or a fastener tape are often placed inside the tab to suppress fluttering of the tab. When the sizes of tabs on left and the right are the same, or the size of a tab disposed on the lower side is larger than the size of the other tab, the upper and lower tabs are bonded to each other at the time of providing a double-sided tape or a fastener tape inside the tab disposed on the upper side.
It is preferable to provide a cover member 10 that covers the opening and closing portion 5 at the time of closing the opening and closing portion 5, and exposes the opening and closing portion 5 at the time of opening the opening and closing portion 5. The cover member 10 is formed of a fabric identical to that of a body part, and the cover member 10 can be kept in a closed state by a double-sided tape, a fastener tape or the like.
The garment is produced in the following manner. The fabric that forms the garment is cut into parts such as the upper garment 1, the hood portion 3, the leg portions 21 a and 21 b, the first tab (large) 8 a, the first tab (small) 8 b, the second tab (large) 9 a, and the second tab (small) 9 b.
Examples of the method of joining the parts include sewing with a sewing thread, welding with an ultrasonic wave or a high-frequency sewing machine, and bonding with an adhesive tape. In addition, the jointed portion can be reinforced with a resin tape or the like. In addition, the first tab (large) 8 a and the first tab (small) 8 b, the second tab (large) 9 a and the second tab (small) 9 b, and fasteners are attached to the opening and closing portion 5 on the left and the right, and the cover member 10 is attached to the opening and closing portion 5 on one of the right or the left to cover the opening and closing portion 5. In addition, a stretchable material such as rubber is sewn to a hood hem opening 30, a sleeve hem, a bottom hem and the like.
The garment is put on and taken off in the following manner. To put on the garment, the body is put in the garment from the opening and closing portion 5, and fitted with the garment, and the hood portion 3 is put on the body. Subsequently, the slider 7 of the fastener is moved to the position of the upper end of the zipper, and the opening and closing portion 5 is closed. Thereafter, the first tab (large) 8 a and the first tab (small) 8 b, the second tab (large) 9 a and the second tab (small) 9 b, and the cover member 10 are closed to cover the opening and closing portion 5.
Also, to take off the garment, the cover member 10, the first tab (large) 8 a and the second tab (large) 9 a are opened to expose the opening and closing portion 5. Subsequently, the tabs are opened in the left and right in the order of the first tab (large) 8 a and the first tab (small) 8 b, and the second tab (large) 9 a and the second tab (small) 9 b so that the opening and closing portion 5 is opened. Next, the head is released from the hood portion 3, and both the sleeves are unfastened. The garment is drawn down, and finally both the legs are drawn out to take off the garment.
Specific examples of the garment include antifouling protective garments and chemically protective garments.

EXAMPLES

Next, our garments will be described further in detail by way of examples. Quality evaluation in examples which was carried out by the following method.
(1) First tab (large) 8 a and first tab (small) 8 b, and second tab (large) 9 a and second tab (small) 9 b

Measurement of Undressing Time

Undressing was started in a state in which an over all type garment was worn, and the time until completion of undressing to the ankle was measured.
(2) Evaluation on whether a hand touches a slider of the garment during undressing:
Evaluation was performed on the basis of the following criteria: the sample is rated “◯” when the slider is not touched during undressing; and the sample is rated “x” when there is the possibility that the slider is touched.

Example 1

A vertically continuous over all type garment was fabricated using a non woven fabric obtained by providing a non woven fabric on each of the front and back sides, and disposing a waterproof and moisture-permeable film between the non woven fabrics on the front and back sides. To join each position, welding was performed with a seam margin of 1 cm using an ultrasonic welding machine, and welded portions were bonded with a resin tape. A first tab (large) 8 a and a first tab (small) 8 b to be sewn to an opening and closing portion 5 were positioned at a distance of 30 cm from a second tab (large) 9 a and a second tab (small) 9 b to be sewn to the opening and closing portion 5, a slider 7 having no lock was attached to a zipper 6, and a distance 11 a to a zipper insertion was 1 cm. A cover member 10 was sewed to cover the opening and closing portion 5 with the cover member 10. The first tab (large) 8 a and the second tab (large) 9 a were disposed under the cover member 10. Rubber was sewn to the opening portion 30, a sleeve hem, and a bottom hem. Results are shown in Table 1.
As shown in Table 1, the tabs were disposed under the cover member 10 and, therefore, it was possible to shorten the uncovering time because it was possible to open the cover member 10 concurrently with opening the tabs for undressing. In addition, it was not necessary to touch the slider 7 during undressing and, therefore, the body was not contaminated.

Example 2

A vertically continuous over all type garment was fabricated using a non woven fabric identical to that in Example 1 as a fabric. To join each position, sewing was performed with a seam margin of 0.7 cm using an overlock machine. A first tab (large) 8 a and a first tab (small) 8 b to be sewn to an opening and closing portion 5 were positioned at a distance of 25 cm from a second tab (large) 9 a and a second tab (small) 9 b to be sewn to the opening and closing portion 5, a slider 7 having no lock was attached to a zipper 6, and a distance 11 a to a zipper insertion was 3 cm. A cover member was sewed to cover the opening and closing portion 5 with the cover member 10. The first tab (large) 8 a and the second tab (large) 9 a were disposed under the cover member 10. Rubber was sewn to the opening portion 30, a sleeve hem, and a bottom hem. Results are shown in Table 1.

In addition, it was not necessary to touch the slider during undressing and, therefore, the body was not contaminated.

Example 3

A vertically continuous over all type garment was fabricated using a 100-percent-cotton woven fabric as a fabric. To join each position, sewing was performed with a seam margin of 0.7 cm using an overlock machine. A first tab (large) 8 a and a first tab (small) 8 b to be sewn to an opening and closing portion 5 were positioned at a distance of 35 cm from a second tab (large) 9 a and a second tab (small) 9 b to be sewn to the opening and closing portion 5, a slider 7 having no lock was attached to a zipper 6, and a distance 11 a to a zipper insertion was 1 cm. A cover member was sewed to cover the opening and closing portion 5 with the cover member 10. The first tab (large) 8 a and the second tab (large) 9 a were disposed under the cover member 10. In addition, rubber was sewn to a sleeve hem and a bottom hem. Results are shown in Table 1.
As shown in Table 1, the tabs were disposed under the cover member 10 and, therefore, it was possible to shorten the uncovering time because it was possible to open the cover member 10 concurrently with opening the tabs for undressing. In addition, it was not necessary to touch the slider 7 during undressing and, therefore, the body was not contaminated.

Example 4

An upper garment was fabricated using a woven fabric identical to that in Example 3 as a fabric. To join each position, sewing was performed with a seam margin of 0.7 cm using an overlock machine. A first tab (large) 8 a and a first tab (small) 8 b to be sewn to an opening and closing portion 5 were positioned at a distance of 30 cm from a second tab (large) 9 a and a second tab (small) 9 b to be sewn to the opening and closing portion 5, a slider 7 having no lock was attached to a zipper 6, and a distance 11 a to a zipper insertion was 1 cm. A cover member 10 was sewed to cover the opening and closing portion 5 with the cover member 10. The first tab (large) 8 a and the second tab (large) 9 a were disposed under the cover member 10. In addition, rubber was sewn to a sleeve hem and a bottom hem. Results are shown in Table 1.
As shown in Table 1, the tabs were disposed under the cover member 10 and, therefore, it was possible to shorten the uncovering time because it was possible to open the cover member 10 concurrently with opening the tabs for undressing. In addition, it was not necessary to touch the slider 7 during undressing and, therefore, the body was not contaminated.

Comparative Example 1

As with Example 1, a vertically continuous over all type garment was fabricated using as a fabric a non woven fabric obtained by providing a non woven fabric on each of the front and back sides, and disposing a waterproof and moisture-permeable film between the non woven fabrics on the front and back sides. To join each position, welding was performed with a seam margin of 1 cm using an ultrasonic welding machine, and welded portions were bonded with a resin tape. Only one tab (large) was sewn to an upper end of an opening and closing portion 5 on the left side of the opening and closing portion 5, a slider having a lock was used as the slider 7 to be attached to a zipper 6, and a distance 11 a to a zipper insertion was 0 cm. A cover member 10 was sewed to cover the opening and closing portion 5 with the cover member 10. The tab was disposed on the cover member 10. In addition, rubber was sewn to a hood hem, a sleeve hem, and a bottom hem. Results are shown in Table 1.
As shown in Table 1, the tab was disposed on the cover member 10 and, therefore, it was necessary to open the tab and the cover member 10 in this order during undressing so that much time was taken to undress. In addition, since a hand touches the slider during undressing, a body may be contaminated.
Comparative Example 2
As with Example 1, a vertically continuous over all type garment was fabricated using as a fabric a non woven fabric obtained by providing a non woven fabric on each of the front and back sides, and disposing a waterproof and moisture-permeable film between the non woven fabrics on the front and back sides. TO join each position, welding was performed with a seam margin of 1 cm using an ultrasonic welding machine, and welded portions were bonded with a resin tape. A first tab (large) 8 a was sewn only to an upper end 11 of the opening and closing portion, a slider having no lock was used as the slider 7 to be attached to a zipper 6, and a distance 11 a to a zipper insertion was 1 cm. A cover member 10 was sewed to cover the opening and closing portion 5 with the cover member 10. The tab (large) 8 a was disposed on the cover member 10. In addition, rubber was sewn to a hood hem, a sleeve hem, and a bottom hem.

Results are shown in Table 1.

As shown in Table 1, the tab was disposed on the cover member 10 and, therefore, it was necessary to open the tab and the cover member 10 in this order during undressing so that much time was taken to undress. In addition, since a hand touches the slider during undressing, a body may be contaminated.
