Abstract
Description
[Technical Field]
[0001] This invention relates to trousers whose entire lower crotch area can be opened and closed. [Background technology]
[0002] Pants that can be opened up to the crotch area are already known, for example, as described in Patent Document 1. These pants have a wide front opening. The front opening is opened by pulling the slider up from the bottom to the top, and closed by pulling it down from the top to the bottom. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 06-033915 Summary of the Invention [Problem to be solved by the invention]
[0004] The trousers described in Patent Document 1 were devised in response to the fact that, until now, relatively few pajamas, sweatshirts, and other trousers had front openings, which caused considerable inconvenience when urinating. This device has a front opening that runs directly from the waist to the crotch, and can be opened by sliding a slider from bottom to top. This configuration makes it easy to put in and take out private parts, preventing incontinence and urinary leakage. However, this device is primarily intended to facilitate urination, and is not sufficient for general excretion, especially bowel movements.
[0005] The object of the present invention is to provide pants that are convenient for general use. [Means for solving the problem]
[0006] The characteristic feature of this device is that the entire crotch portion can be opened and closed, and it comprises a trouser body with a stretchable waist, and a slide zipper that extends from the upper center of the front of the trouser body, through the crotch portion of the trouser body, to the upper center of the back of the trouser body, and the entire crotch portion can be opened by moving the pull tab of the slide zipper.
[0007] With this configuration, for example, by sliding the pull tab from the upper center of the front body to the upper center of the back body, the entire crotch area can be opened and closed, preventing residual urine and urine leakage due to tightness or pressure after urination. Also, since there is no need to remove the belt or waistband when urinating, the preparation steps for urination can be significantly shortened, improving convenience especially for the elderly and those requiring care.
[0008] Furthermore, this configuration allows the pants to be worn for all excretions, including urination and defecation, while still wearing the pants, and the size of the opening in the crotch area can be adjusted by operating the pull tab depending on the purpose. Furthermore, by making the pants shaped to accommodate both male and female body types, they can be used as pants with the same structure regardless of gender. In this way, by providing a unisex structure that can be worn comfortably by both men and women and a configuration that allows excretion without removing the belt or waist fasteners, it is possible to reduce the burden on both the caregiver and the wearer and shorten the time it takes to urinate.
[0009] Another characteristic feature is that a pair of pull tabs are provided on the front body side, and the garment can be opened in both directions by moving the pair of pull tabs upward and downward, respectively.
[0010] According to this configuration, excretion can be performed by operating the pull tab depending on the purpose, such as urination, defecation, etc. In addition, the movement distance of the slide fastener is short, making it easy to operate.
[0011] Another characteristic feature is that the slide fastener is provided with a plurality of blind portions that hide the heads of the pair of pull tabs.
[0012] According to this configuration, by installing multiple blinds, it is possible to prevent malfunctions before they occur. Also, if the slide fastener malfunctions, the blinds can prevent the most important front from opening. Furthermore, the blinds are fashionable and reduce the exposure of the pull tab.
[0013] Another characteristic feature is that a pair of pull tabs are provided in the middle part of the crotch portion, and the pull tabs can be moved around the middle part toward the front body and the back body, respectively, to open in both directions.
[0014] According to this configuration, excretion can be performed by operating the pull tab depending on the purpose, such as urination, defecation, etc. In addition, the movement distance of the slide fastener is short, making it easy to operate.
[0015] Another characteristic feature is that the entire crotch portion is opened by moving the pull tab of the slide fastener from the front body side to the back body side.
[0016] In this configuration, the entire lower crotch area opens when the pull tab of the slide fastener is moved from the front to the back, and closes when the pull tab is moved from the back to the front, so there is no pressure on the crotch area and it is possible to eliminate the feeling of residual urine or urine leakage after urination.

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the accompanying drawings. However, the present invention is not limited to the following embodiments and various modifications are possible without departing from the spirit of the present invention.
[0019] [Pants structure] As shown in FIGS. 1 to 6, trousers 100 include a trouser body 10 with a stretchable waist 11 and a slide fastener 6. The trouser body 10 has a crotch portion 1 for accommodating the crotch area and a pair of crotch portions 3 into which the legs are inserted. The front portion is referred to as a front body 4, and the back portion is referred to as a back body 5. The crotch portion 1, crotch portion 3, front body 4, and back body 5 are integrally formed, and the slide fastener 6 extends from the upper center of the front body 4, via the crotch portion 2, to the upper center of the back body 5. A first stopper 8a (stopper 8) is provided on the back body 5 side to limit the movement of the pull tab 7. A cover cloth 9 may be provided to hide the first stopper 8a (stopper 8) (see the dashed line in FIG. 2).
[0020] [Pants according to the first embodiment] A first embodiment will be described with reference to FIGS. 1 to 3. As shown in FIGS. 1 to 3, trousers 100 of the first embodiment have a slide zipper 6 that can open and close the entire crotch region 2. The slide zipper 6 extends from the upper center of the front body 4, through the crotch region 2, to the upper center of the back body 5. In this embodiment, the pull tab 7 of the slide zipper 6 is located at the upper center of the front body 4 when closed, and at the upper center of the back body 5 when the entire crotch region 2 is open. The entire crotch region 2 is opened by moving the pull tab 7 from the front body 4 side to the back body 5 side. Alternatively, the slide zipper 6 may have the pull tab 7 located at the upper center of the back body 5 when closed, and at the upper center of the front body 4 when the entire crotch region 2 is open. In this case, the entire crotch region 2 may be opened by moving the pull tab 7 from the back body 5 side to the front body 4 side.
[0021] By moving the pull tab 7 from the front body 4 side to the back body 5 side, the entire crotch portion 2 opens, and by moving the pull tab 7 from the back body 5 side to the front body 4 side, it closes, so there is no pressure on the crotch area and it is possible to eliminate the feeling of residual urine after urination and urine leakage. In addition, since the size of the opening in the entire crotch portion 2 can be adjusted as desired, it is possible to defecate while wearing the pants 100.
[0022] In addition, the entire crotch section 2 can be opened and closed, making it easy to change diapers for bedridden or sick people. Furthermore, the pull tab 7 can be operated while the waist section 11 is fastened, so there is no need to remove the belt or waist section, and excretion can be performed quickly.
[0023] [Trousers according to the second embodiment] The second embodiment will be described with reference to Figures 4 to 6. As shown in Figures 4 to 6, trousers 100 of the second embodiment have a pair of pull tabs 7 of a slide fastener 6 provided at the intermediate section 8b of the crotch section 2. The pull tabs 7 are slid around the intermediate section 8b toward both the front body 4 and the back body 5, opening the entire crotch section 2 in each direction. In addition, to restrict the movement of the pull tabs 7, a first stopper 8a (stopper 8) is provided on the front body 4 side, and a second stopper 8c (stopper 8) is also provided on the back body 5 side. The other configurations, functions, and effects are the same as those of the first embodiment, so description thereof will be omitted.
[0024] The pair of pull tabs 7 of this embodiment can be opened and closed by operating them in both directions, toward the front body 4 and the back body 5, around the middle part 8b of the crotch region 2, so they can be used for defecation and urination. In addition, the movement distance of the slide fastener 6 is short, making it easy to operate.
[0025] [Third embodiment of pants] A third embodiment will be described with reference to Fig. 7. As shown in Fig. 7, trousers 100 of the third embodiment have a pair of pull tabs 7 of a slide fastener 6 provided between the upper center of the front body 4 and the crotch region 2, and the pair of pull tabs 7 can be positioned at any position on the front body 4. In this embodiment, the slide fastener 6 is provided with multiple (three in this embodiment) blinding portions 12, which function as hook-and-loop fasteners to hide the heads of the pair of pull tabs 7. The blinding portions 12 add a fashionable touch and suggest that each of the pair of pull tabs 7 can be slid both upwards and downwards.
[0026] As in this embodiment, by installing the blinding portions 12 in multiple locations (three locations in this embodiment) in the middle of the top and bottom, it is possible to prevent malfunctions from occurring. Also, if the slide fastener 6 malfunctions, the blinding portions 12 can prevent the most important front portion from opening. Furthermore, the blinding portions 12 are highly fashionable and reduce the exposure of the pull tab 7.
[0027] [Other embodiments] (1) A first slide fastener that can be opened from top to bottom or bottom to top may be provided on the front body 4 side, and a second slide fastener that can be opened from top to bottom or bottom to top may be provided on the back body 5 side of the crotch section 2, with a stopper 8 provided on the back body 5 side or the front body 4 side. If the pull tabs 7 of the first slide fastener and the second slide fastener are arranged opposite each other on the back body 5 side or the front body 4 side of the crotch section 2, the slide fasteners 6 on the front body 4 side and the back body 5 side can be operated independently, making it possible to open only the front body 4 side, only the back body 5 side, or both. This allows the opening range to be flexibly adjusted depending on the wearer's usage conditions, the caregiver's working conditions, and the application. (2) Opening and closing means such as a hook-and-loop fastener may be used instead of the slide fastener 6. This makes it easier to change diapers in nursing care settings. [Industrial Applicability]
