Title: Bodysuit

Description:
BACKGROUND 
     Most people change their clothes often, and most parents change their babies&#39; diapers and clothes often. Most parents change a baby&#39;s diaper multiple times in a day; some even change diapers as much as ten times per day. Many parents change the diaper for their baby every two to three hours. Clothes that are difficult to put on and take off can make changing diapers or outfits complicated and time consuming. Wearing and/or having a baby wear clothes that can quickly be taken off and put on can make changing easier and facilitate the processes for changing a baby&#39;s diaper. Clothes that allow for quick, easy access to the diaper area would be beneficial. Clothing that is easy and quick to put on and take off is highly desirable and may save time and money. For older wearers, a bodysuit that allows the wearer to use the bathroom more easily without requiring full removal of the bodysuit would be desirable as well. 
     Securing a bodysuit opening or flap using many snaps or buttons may cause difficulties. For example, the snaps or buttons may be easy to misalign and may be time-consuming to match with respective snaps, buttons, and/or button holes. If the snaps or buttons are arranged on the bottom portion of the child bodysuit, the opening or a flap might come apart when the child crawls, rolls, or walks around, so the parent may need to check the bodysuit again and again over time to make sure that the bodysuit continues to remain buttoned up. It is also possible that the buttoned or snapped area could become caught on something as the baby crawls or moves around. Snaps or buttons that need to be engaged or disengaged every time might be easily broken after frequent use. In other words, the snaps may lose their adhesive function, and the buttons may break off from the bodysuit. In addition, snaps/buttons might rip off and tear the garment around the snaps/buttons. If any snaps or buttons did come off, they could be a choking hazard for a child. A less complicated construction that does not require buttons or snaps may allow a manufacturer to reduce costs. 
     Disclosed herein are new garments, devices, components, systems, and methods for improving ease of use, access, removal, and changing of clothing, which avoid certain disadvantages. These may provide easier access and use for one-piece clothing or bodysuits. For example, these may help make changing clothes easier or changing diapers of a baby, and may provide other benefits as described herein. The concepts described herein may be applied to a wide variety of clothing, etc. 
     SUMMARY OF THE INVENTION 
     Embodiments of, and enhancements for, clothing, components, assemblies, systems, methods, etc. for easier access and use, are described herein. A variety of embodiments are encompassed, but a few non-limiting examples are described in more detail. 
     In one embodiment, a bodysuit is provided, wherein the bodysuit comprises a back panel having a top piece and a bottom piece thereof to define a receiving opening for allowing the user to easily put on or take off the bodysuit. A bodysuit can be a one-piece article of clothing. 
     In one embodiment a bodysuit is provided, wherein there are no snaps or buttons arranged on the front panel of the bodysuit so the user doesn&#39;t need to spend lots of time to engage or disengage snaps or buttons one by one so as to save more time to put on or take off the bodysuit. In one embodiment, the bodysuit does not include snaps or buttons on the back panel. In one embodiment, the bodysuit does not include any snaps or buttons at all. 
     In one embodiment, the bottom piece of a back panel of the bodysuit overlaps over the top piece of the back panel of the bodysuit to define an overlapping area, which may help protect against cold wind and/or unwanted materials falling into the receiving opening. In one embodiment, the top piece of a back panel of the bodysuit overlaps over the bottom piece of the back panel of the bodysuit to define an overlapping area, which may protect against cold wind and/or unwanted materials falling into the receiving opening. 
     In one embodiment, the bodysuit may comprise a front panel having a top piece and a bottom piece that combine to define a receiving opening for allowing the user to easily put on or take off the bodysuit. The bottom piece of the front panel of the bodysuit may overlap over the top piece of the front panel of the bodysuit to define an overlapping area for protecting cold wind or unwanted materials falling into the receiving opening, or the top piece of the front panel of the bodysuit may overlap over the bottom piece of the front panel of the bodysuit to define an overlapping area for protecting cold wind or unwanted materials falling into the receiving opening. 
     In one embodiment, a receiving opening of a bodysuit may be longitudinally formed from one side of a seam between the front panel and the back panel of the bodysuit to the other side of a seam therebetween, wherein the width of receiving opening may be smaller than the width of the back panel so as to aid the top opening end of the bottom piece to stay in position. 
     In one embodiment, a method for the user to quickly put on or take off the bodysuit is provided according to the preferred embodiment of the present invention so as to facilitate and simplify the steps for putting on or taking off the bodysuit. 
     The bodysuits described herein may be constructed inexpensively (including less expensively than a bodysuit with many buttons and/or snaps) and do not have a complicated structure, which may help to decrease the manufacturing cost and related manufacturing processes of the present invention. 
     The bodysuits described herein and designed so as to minimize the manufacturing cost. The bodysuits are easy to operate and time-saving so as to be more convenient for the user to put on or take off the bodysuit. Therefore, the bodysuits provide an economic and efficient solution not only for providing a bodysuit to allow the user to quickly put on and take off the bodysuit, but also for reducing the manufacturing cost for the manufacturer. 
     The foregoing and other objects and advantages may be attained by a bodysuit, comprising a unitary body which includes a front panel and a back panel that form a head opening at a seam position between top ends of the front panel and the back panel; wherein the back panel may be adapted for putting on and taking off the bodysuit and may include a top piece and a bottom piece. The bottom piece may have a top opening end overlapped with the top piece to define a receiving opening, or the top piece may have a bottom opening end overlapped with the bottom piece to define a receiving opening. The top opening end of the bottom piece may stay in a waist position of a back of the user while the user puts on the bodysuit or, when the user takes off the bodysuit, the top opening end of the bottom piece of the back panel may be pulled down towards to the user&#39;s leg and pass over the user&#39;s crotch and legs to take off the bodysuit. 
     The foregoing and other additional advantages and features will become apparent from the description which follows and the associated figures, and may be realized by means of the instrumentalities and combinations and methods described, including those in the appended claims. 
     In one embodiment, clothing, devices, apparatuses, components, systems, etc. may include any features described herein, depicted in the figures, or known in the art. And these may be used in various methods including any combination of the various steps described herein and any steps known in the art.

     DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS 
     Described herein are clothes, devices, components, assemblies, systems, methods, etc. associated with covering a person&#39;s body in an easy and efficient way. The description and accompanying figures, which describe and show certain embodiments, are made to demonstrate, in a non-limiting manner, several possible configurations of clothing, devices, components, assemblies, systems, etc. and various methods of using them according to various aspects and features of the present disclosure. Accordingly, the disclosure is not limited to the specific embodiments described. Rather, the inventive principles associated with the embodiments described herein, including with respect to the clothing, apparatuses, devices, components, assemblies, systems, methods, etc. described herein, may be applied in a variety of ways, including to other types of clothing, apparatuses, devices, components, assemblies, systems, methods, etc. General and specific clothing, apparatuses, devices, components, assemblies, systems, methods, etc. are described herein sufficiently to enable one to develop a variety of implementations/applications without undue experimentation. In the development of particular applications, numerous implementation-specific decisions will be made to achieve the design-specific goals, which will vary from one implementation/application to another. It will be appreciated that, having access to this disclosure and reading this disclosure, such a development effort would be a routine undertaking for persons of ordinary skill in the art. 
     This document does not intend to distinguish between components that differ in name but not function. In the following discussion and in the claims, the terms “including,” “includes,” “comprising,” “have,” and “has” are used in an open-ended fashion, and thus should be interpreted to mean “including, but not limited to.” The word “or” is used in the inclusive sense (i.e., “and/or”) unless a specific use to the contrary is explicitly stated. 
     The following description is disclosed to enable any person skilled in the art to make and use the present invention. Preferred embodiments are provided in the following description only as examples and modifications will be apparent to those skilled in the art. The general principles defined in the following description can be applied to other embodiments, alternatives, modifications, equivalents, and applications without departing from the spirit and scope of the present invention. 
     As shown in  FIG. 1A  and  FIG. 1B  of the drawings, an exemplary bodysuit  10  is provided, wherein the bodysuit  10  comprises a unitary body  11  having a front panel  12  and a back panel  13  that form a head opening  20 , wherein the back panel  13  comprises a top piece  131  and a bottom piece  132  that has a top opening end  1321  to define a receiving opening  30 . The front panel  12  is a front facing side (relative to a wearer&#39;s body) of the bodysuit  10 , and the back panel  13  is the back facing side of the bodysuit  10 . (However, in one embodiment, the panel  12  may be a back panel and the panel  13  may be a front panel, i.e., with the opening  30  on a front side of a wearer.) The front panel  12  may be made of a unitary piece of material or of multiple pieces (e.g., pieces sewn together). The front panel  12  could be constructed to appear as a one piece bodysuit or may include additional features to make it look like a two-piece article of clothing. For example, the front panel  12  may include a flap sewn in the middle to overlap and make the front panel appear as two pieces, e.g., as a shirt and pants/shorts. The front panel may include one or more pockets as well, e.g., similar to pants pockets and/or a shirt pocket. The front panel, the back panel, the top piece of the back panel, the bottom piece of the back panel, may each be combination pieces formed of multiple other pieces, panels, components, etc. 
     The bodysuit  10  may be made of any kinds of material that are suitable for clothing, including materials suitable for clothing a child or baby. In one embodiment, the bodysuit  10  is preferably made of cotton, but polyester, cashmere, silk, wool, rayon, stretchy materials, or blends or combinations of these or others maybe be used. In one embodiment, multiple materials are used to form bodysuit  10 . In one embodiment, an inner material and an outer material of all or portions of bodysuit  10  may be different and have different physical properties. For example, an inner material of bodysuit  10  may be lower friction (e.g., silk) to facilitate ease of putting on and taking off of bodysuit  10 . Optionally, an inner material could be warmer material or lined with a warmer material for keeping the wearer/user warm (e.g., similar to thermal underwear material, fleece, or other warm materials). 
     In  FIGS. 1A and 1B , the bodysuit  10  is illustrated as a child or baby bodysuit; however, the bodysuit can also be designed and/or configured as other kinds of garments, such as swimsuits, pajamas, doll/toy clothing, undergarments (e.g., thermal undergarments), adult bodysuits, senior garments (e.g., for easy changing of adult diapers), youth or teenage bodysuits, and onesies for babies and older people, including toddlers, children, youths, teenagers, adults, and seniors. For example,  FIGS. 5A and 5B  show pictures of an embodiment of a bodysuit for an older child. Bodysuits made for babies and toddlers (or children still in diapers), may provide easy access to the diaper for changing. However, the configurations and features described herein, when used on bodysuits for larger children, youths, teenagers, adults, seniors, etc., may provide easier access for using the toilet. For example, a wearer wishing to use the toilet, may pull down the top end and elastic band of the bottom piece  132  without having to remove the bodysuit entirely from the wearer&#39;s legs. The top end and elastic band of the bottom piece  132  may be easily pulled down over the buttocks sufficiently to allow the person to use the toilet, then pulled back up over the buttocks (e.g., to rest in the waist or lower back region), all without having to entirely remove the bodysuit from the legs. 
     As shown in  FIG. 1B , the top piece  131  of the back panel  13 , in one embodiment, may extend from a seam between the front panel  12  and the back panel  13  to the position which passes through the receiving opening  30 , and the bottom piece  132  of the back panel  13  may extend from the bottom end of the back panel to the waist portion of the bodysuit  10 . In such a manner, the top piece  131  of the back panel  13  and the bottom piece  132  of the back panel  13  may define an overlapping area  40  that a bottom end (e.g., a bottom end formed as flap) of the top piece  131  of the back panel  13  may be downwardly extended below the waist portion of the bodysuit  10 , and the top opening end  1321  of the bottom piece  132  of the back panel  13  may be upwardly extended over the butt portion of the bodysuit  10  to reach the waist portion thereof. The bottom end of the top piece  131  of the back panel  13  may be tucked into the top of the bottom piece  132  of the back panel  13 . In one embodiment, the bottom end of the top piece  131  may be sewn in such a way that the bottom end is predisposed to be tucked in, e.g., the seam may extend inside and below the top opening end  1321 . This can help ensure that the bottom edge of the top piece  131  is tucked inside the top opening end  1321  and can help ensure that the bodysuit looks more like a one-piece outfit in the back. The bottom end and bottom edge of the top piece  131  may extend down to various positions/lengths, e.g., the bottom edge of the top piece  131  may extend below the waist, below the middle of the buttocks, below the buttocks of the wearer/user, and/or any point in between. The lower the bottom edge extends the more effective it may be at protecting against drafts or, cold air, etc. reaching the wearer/user or his/her legs through the receiving opening  30 . The bodysuit may look like a one-piece bodysuit from the front. 
     As shown in  FIG. 4 , the top piece  131  of the back panel  13 , in one embodiment, may extend from a seam between the front panel  12  and the back panel  13  to a position which passes over the receiving opening  30 , and the bottom piece  132  of the back panel  13  may extend from the bottom end of the back panel to the waist portion of the bodysuit  10 . The top piece  131  of the back panel  13  and the bottom piece  132  of the back panel  13  may define an overlapping area  40  that a bottom end (e.g., a bottom end formed as flap) of the top piece  131  of the back panel  13  may be downwardly extended below the waist portion of the bodysuit  10 , and the top opening end  1321  of the bottom piece  132  of the back panel  13  may be upwardly extended over the butt portion of the bodysuit  10  to reach the waist portion thereof. The bottom of the top piece  131  of the back panel  13  may extend over and cover the top of the bottom piece  132  of the back panel  13 .  FIG. 4  includes a cut out region for the purpose of showing the top opening end  1321  and elastic band underneath the top piece  131  in the overlapping area  40 . In one embodiment, the bottom end of the top piece  131  may be sewn in such a way that the bottom end of the top piece  131  is predisposed to overlap and cover the top portion of the bottom piece  132 , e.g., the seam may extend below the top opening end  1321  along the outside of the bottom piece  132  (for example, along the outer edges or sides). This can help ensure that the bottom edge of the top piece  131  covers the top opening end  1321  and can help ensure that the bodysuit looks similar to a two-piece outfit from the back having a top and bottom, e.g., a shirt and pants/shorts. The bottom end and bottom edge of the top piece  131  may extend down to various positions/lengths, e.g., the bottom edge of the top piece  131  may extend below the waist, below the middle of the buttocks, below the buttocks of the wearer/user, and/or any point in between. The lower the bottom edge extends the more effective it may be at protecting against drafts or, cold air, etc. reaching the wearer/user or his/her legs through the receiving opening  30 . The bodysuit may still look like a one-piece bodysuit from the front, e.g., the front of the bodysuit of  FIG. 4  may look similar to  FIG. 1A . 
     It is worth mentioning that the overlapping area  40  between the top piece  131  and the bottom piece  132  of the back panel  13  can prevent cool air from passing through the receiving opening  30  of the bodysuit  10 , so even if a receiving opening  30  is located at a back side of the bodysuit  10 , the user may not feel cold. 
     As shown in  FIG. 1B , the receiving opening  30  may be longitudinally formed from one side seam between the front panel  12  and the back panel  13  to another side seam therebetween. And, the width of the receiving opening  30  may be smaller than the width of the back panel  13 , such that the top opening end  1321  of the bottom piece  132  of the back panel  13  is able to stay more easily in a position. Since the width of the receiving opening  30  is smaller than the width of the back panel  13 , the top opening end  1321  of the bottom piece  132  of the back panel  13  can generate an inward-pressed force while the user wears the bodysuit  10 , so the top opening end  1321  of the bottom piece  132  of the back panel  13  may not easily fall down from the waist portion of the user. 
     It is worth mentioning that the top opening end  1321  of the bottom piece  132  of the back panel  13  may be a curved, straight, or other shape opening end. For the ergonomics, while the user wears the bodysuit  10 , a curved shape opening end can attach on the waist portion of the user, such that the curved shape opening end can match with the waist shape of the user&#39;s body, so the top opening end  1321  of the bottom piece  132  of the back panel  13  may stay in the waist portion of the user&#39;s body. 
     Accordingly, the bodysuit  10  may further comprise an elastic band  14  arranged along the top opening end  1321  of the bottom piece  132  of the back panel  13 , wherein the elastic band  14  can be stretched to a predetermined length or a range of lengths so as to expand the size of the receiving opening  30 . Therefore, the elastic band  14  can be pulled to expand the size of the receiving opening  30  for allowing the user to put on or take off the bodysuit  10  through the receiving opening  30 . After the user puts on the bodysuit  10 , the pulled force on the elastic band  14  is released, so the elastic band  14  will return to its original length so as to secure on the waist portion of the user. In one embodiment, the elastic band may expand in length anywhere between 10-100% longer than the original length, though other percentages and lengths are possible. 
     The bodysuit  10  may further comprise a pair of sleeves  15  extended (e.g., integrally extended) from the front panel  12  of the unitary body  11  defining two arm openings  151  for allowing the user to put the user&#39;s arms along the two sleeves  15  through the two arm openings  151 , and a pair of trouser legs  16  downwardly extended (e.g., integrally extended) from the garment body  11 , wherein the user is able to insert the user&#39;s legs into the two trouser legs  16  through the receiving opening  30 , such that the pair of the trouser legs  16  can protect the user&#39;s legs (e.g., from exposure in cold weather) so as to support the user wearing the bodysuit  10  according to the preferred embodiment. The trouser legs  16  may optionally include foot portions on the end of each leg that cover the feet. 
     The bodysuit may include or omit sleeves, trouser legs, or various combinations of these, e.g., trouser legs but no sleeves, sleeves but no trouser legs. As shown for example in  FIG. 2 , the bodysuit  10  can be a vest style bodysuit or onesie, so in this manner, the two arm openings  151 A may be formed at the seam between the front panel  12  and the back panel  13 . In other words, sleeves  15  may be omitted in the bodysuit  10  and, if omitted, the vest style bodysuit may be cooler for the user (e.g., for use in hot weather). In addition, the pair of the trouser legs  16  can be omitted and the bodysuit  10  provided with two leg openings  161  spacedly arranged on the bottom portion of the unitary body  11 , which can be the bottom seam between the front panel  12  and the back panel  13 , so the legs of the user may be inserted through the two leg openings  161  respectively. In one embodiment, trouser legs  16  and/or sleeves  15  may be removably attachable (e.g., using zippers, hook and loop fasteners, snaps/buttons, other fasteners, etc.) to the vest style bodysuit to form a bodysuit more similar to that shown in  FIGS. 1A, 1B, and 4 . 
     The elastic band  14  provides benefits in terms of ease of use, manufacturing, and other things, but can optionally be replaced or supplemented by other components. For example, the bodysuit may include one or more drawstrings, separated elastic bands, pleats, accordion folds, zippers, magnets, snaps, buttons, and/or combinations of some or all of these. In one embodiment, snaps, buttons, and/or magnets arranged on the top opening end  1321  of the bottom piece  132  of the back panel  13  may be attached on the top piece  131  of the back panel  13  by matching with the respective snaps, buttons, and/or magnets on the top piece  131  of the back panel  13  so as to hold the top opening end  1321  of the bottom piece  132  of the back panel  13  in position. In other words, this kind of design (and others described below) can support the elastic band  14  on the top opening end  1321  to stay in position even if the elastic band  14  were to lose its extendable/retractable function after frequent use. 
     In one embodiment, one or more drawstrings may be used instead of or in addition to an elastic band. The drawstring(s) may be used to loosen or tighten the receiving opening  30  in any of the embodiments discussed herein. The drawstring(s) may be pulled to tighten the opening  30  and help hold the bodysuit  10  and bottom piece  132  tightly on the wearer/user. The drawstring(s) may be tied, clamped, fastened, and/or otherwise held in position to help hold the bodysuit  10  and bottom piece  132  tightly on the wearer/user. The drawstring(s) may be untied, unclamped, unfastened, and/or otherwise loosened to help open the receiving opening  30  of the bodysuit  10  for removal or partial removal from the wearer/user. In one embodiment, the drawstring(s) may loop around the waist of the wearer/user in a way that does not significantly alter the appearance of the bodysuit  10 , e.g., so the bodysuit  10  may still resemble a one piece bodysuit as in  FIG. 1A or 2 . For example, a passage way through the fabric or under the outer layer of fabric may be provided for the drawstring(s) to pass through. In one embodiment, loops or slits may be provided around the waist on the inside or outside of the bodysuit through which the drawstring(s) (and/or a belt) may pass. In one embodiment, the drawstring(s) may alternate directions inward and outward passing through slits. In one embodiment, the drawstring(s) may cause bunching, folds, pleats, and/or an accordion-like arrangement of fabric as the drawstring(s) are tightened. This can allow more fabric to be available in the loosened configuration to allow for easier dressing and removal of the bodysuit  10 . In embodiments similar to  FIG. 4 , the bottom portion of the top piece  131  may help to hide any bunching, folds, pleats, and/or accordion-like arrangement of fabric where the bottom portion of the top piece  131  overlaps and covers the top portion of the bottom piece  132 . 
     In one embodiment, multiple elastic bands may be used and may be separated from each other. This may allow different portions of the receiving opening  30  to open or expand in different ways. For example, the opening  30  may be designed to open more in areas where the feet of a wearer are more likely to pass to make putting on and taking off the bodysuit  10  easier. In one embodiment, the top end of the bottom piece  132  may be formed as a flap and elastic bands may attach between edges or corners of the flap to another portion of the bodysuit  10  (e.g., to a side seam or to the front panel  12 ). The elastic bands may act as an expandable tether between portions of the bodysuit  10 . In one embodiment, the flap may form an opening between the flap, an elastic band(s), and another portion of the bodysuit  10  and the opening may increase in size when the flap is pulled outwardly and the elastic band(s) expands. 
     In one embodiment, pleats and/or accordion folds (or other bunching or folding of material) may be used around opening  30 , which may provide additional fabric/material to allow the receiving opening  30  to open wider and make it easier to put on and take off. In one embodiment, pleats and/or folds may be formed with snaps, hook and loop fasteners (Velcro), buttons, magnets, etc. arranged in a manner to make opening and closing of the receiving opening  30  as easy and convenient as possible. 
     In one embodiment, one or more zippers may be used in addition to or instead of the elastic band. For example, zippers may extend from the receiving opening  30  in one or more directions on the top piece  131  and/or the bottom piece  132 . The zippers may allow for expanding or narrowing the receiving opening  30 . In one embodiment, a zipper may extend down the middle of the bottom piece  132  starting from the top edge of the bottom piece  132 . In one embodiment, two zippers may extend down the sides of the bottom piece  132  starting from the top edge of the bottom piece  132 . In one embodiment, one or more zippers may extend up the top piece  131  starting from the bottom edge of the top piece  131 . One or more zippers could also run along the side seams of the top piece  131  or the bottom piece  132 . In embodiments similar to  FIG. 4 , the bottom portion of the top piece  131  may help to hide any zippers where the bottom portion of the top piece  131  overlaps and covers the top portion of the bottom piece  132 . In one embodiment, zippers may be formed along edges of the flap portion of the top piece  131  that is tucked under or covers over the top edge and elastic band of the bottom piece  132  to restrict movement or allow greater movement of the flap portion. 
       FIG. 5A  is a side perspective view of an exemplary bodysuit with an overlapping area similar to that of  FIG. 4 , but configured/designed for an older child.  FIG. 5B  is a back perspective view of the bodysuit of  FIG. 5A  with the lower end of the top piece of the back pulled up to show the underlying top end of the bottom piece of the back. The top piece  131  of the back panel is shown with a seam running down the side to the bottom edge of the top piece  131 . The bottom piece  132  may also include a seam along the side running up to the top edge of the bottom piece  132 . 
     The clothing, bodysuits, components thereof, etc. described herein may be used in a variety of methods. Methods of using the clothing and bodysuits or any of their components/features may include any of the steps discussed anywhere in this description or the summary.
