Title: Multi-purpose mat system

Description:
FIELD OF THE DISCLOSURE 
     The present disclosure relates to a mat system, and particularly to a multi-purpose mat system suitable for utilizing as a picnic mat, a flag, or a folding stretcher. The support frame of the mat system may enable to be collapsed into smaller pieces with the mat being folding in a compact size in order to facilitate the transportation. 
     BACKGROUND OF THE DISCLOSURE 
     Generally, any number of method and systems have been utilized to move a patient from one location to another. The patients could be moved or transported by a conventional stretcher or bed by several attendants. The portable stretcher are popular and well known devices which function well under most circumstances, and the conventional portable stretcher usually comprises a fabric sheet supported by the support frames in order to support the patient on the fabric sheet, However because these stretchers are bulky and heavy, they occupy a large space for storage when the spaces in the vehicle or ambulance have been already limited. 
     In some situations, it is preferable that the portable stretcher can be collapsed in a compact size. Many of the improved portable stretchers have been developed to enable the stretcher to be folded into a compact folded state to facilitate carrying and transportation. However, even if the current foldable stretcher could be stored in a relative smaller space, it could not be able to utilize in any time if people forget to put it in the vehicle. Accidents happen unexpectedly and people could not always have the stretcher in hand. 
     In another non-limiting example, currently-available foldable stretcher have several joints where the support frames are connected at, and the foldable stretcher could be folded via the joints. However, these joints affects the overall structure of the stretcher. Another drawbacks for the current-available foldable stretcher is that the overall structure is not strong enough to overcome an average weight of the body, and in such situation, the body may flip over or fall down therefrom during the transportation. 
     To overcome this known problem, there may exist a desire to develop a multi-purpose mat for utilizing in various kinds of purposes, such as picnic mats, flags, or stretchers. Therefore, people could store or bring the mat by the side so as to face emergency situations.

Here, the first support frame  122  comprises the plurality of the first support members  1221  which could be detachably coupled with each other, and the second support frame  121  comprises the plurality of the second support members  1211  which could be detachably coupled with each other. 
     Accordingly, in an embodiment, the plurality of the first support members  1221  could be coupled with each other by various kinds of connection method and the plurality of the second support members  1211  could be coupled with each other by various kinds of connection method. For example, each of the first support members  1221  and the second support members  1211  may selectively comprise a screw portion or a bolt portion, wherein the screw portion may be configured to engage with the bolt portion to connect the first support member  1221  with one another (e.g., another one of the first support member  1221 ) and connect the second support member  1211  with one another (e.g., another one of the second support member  1211 ). 
     In an embodiment, the mat  100  can be a rectangular shape. The mat  100  may be a square shape based on the needs of the purposes. 
     It should be understood that the above-described shapes are exemplary and any other shapes which are adopted to fold the mat  100  in order to make the left loops  111  being aligned with the right loops 112  can be utilized as the shape of the mat  100 . 
     According to all of the embodiments described above, the front side  117 , the rear side  118 , the left side  101 , and the right side  102  of the mat  100  may be folded towards either the top face  113  or the bottom face  114  of the mat  100 , and to be sealed (or stitched) on the top face  113  or the bottom face  114  to form folds or stems. It is noted that the fold or stems may be able to enhance an overall structure of the mat  100 . 
     According to all of the embodiments described above, the loops  110 , including the right loops  112  and the left loops  111 , may be stitched on the folds or stems of both of the right side  102  and the left side  101 , or/and both of the front side  117  and the rear side  118 . During the uses of the multi-purpose mat system  10 , the support frame  12 , including the first support frame  122  and the second support frame  121 , may be biased against the loops  110 , and in this manner, the loops  110  may sustain most of the weight of the patient&#39;s body supported on the mat  100 . Therefore, the folds or stems could enhance the adhesion of the loops  110 , including the right loops  112  and the left loops  111 , and prevent the loops  110  bumping off or falling down from the mat  100 . 
     Similarly, while operations and/or methods may be depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations and/or method steps be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. 
     Many alterations and modifications may be made by those having ordinary skill in the art without departing from the spirit and scope of the disclosed embodiments. Therefore, it must be understood that the illustrated embodiments have been set forth only for the purposes of example and that it should not be taken as limiting the embodiments as defined by the following claims. For example, notwithstanding the fact that the elements of a claim are set forth below in a certain combination, it must be expressly understood that the embodiment includes other combinations of fewer, more or different elements, which are disclosed herein even when not initially claimed in such combinations. 
     Thus, specific embodiments and applications of the multi-purpose mat system have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those already described are possible without departing from the disclosed concepts herein. The disclosed embodiments, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms “comprises” and “comprising” should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Insubstantial changes from the claimed subject matter as viewed by a person with ordinary skill in the art, now known or later devised, are expressly contemplated as being equivalent within the scope of the claims. Therefore, obvious substitutions now or later known to one with ordinary skill in the art are defined to be within the scope of the defined elements. The claims are thus to be understood to include what is specifically illustrated and described above, what is conceptually equivalent, what can be obviously substituted and also what essentially incorporates the essential idea of the embodiments. In addition, where the specification and claims refer to at least one of something selected from the group consisting of A, B, C and N, the text should be interpreted as requiring at least one element from the group which includes N, not A plus N, or B plus N, etc. 
     The words used in this specification to describe the various embodiments are to be understood not only in the sense of their commonly defined meanings, but to include by special definition in this specification structure, material or acts beyond the scope of the commonly defined meanings. Thus if an element can be understood in the context of this specification as including more than one meaning, then its use in a claim must be understood as being generic to all possible meanings supported by the specification and by the word itself. 
     The definitions of the words or elements of the following claims therefore include not only the combination of elements which are literally set forth, but all equivalent structure, material or acts for performing substantially the same function in substantially the same way to obtain substantially the same result. In this sense it is therefore contemplated that an equivalent substitution of two or more elements may be made for any one of the elements in the claims below or that a single element may be substituted for two or more elements in a claim. Although elements may be described above as acting in certain combinations and even initially claimed as such, it is to be expressly understood that one or more elements from a claimed combination can in some cases be excised from the combination and that the claimed combination may be directed to a subcombination or variation of a subcombination.
