CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This Application claims the benefit of a U.S. provisional application No. 60/892,488 entitled “Mat Having Padded Portion”, filed Mar. 1, 2007, which is hereby incorporated by reference in its entirety. 
     
    
     BACKGROUND 
       [0002]    Many activities that take place on the ground or on the floor may be made easier and more pleasant with the use of a mat or other padded surface. Many mats have been designed for sleeping outdoors or for use at the beach. Various sports have also required surfaces with different degrees of softness and various dimensions resulting in the development of a variety of athletic mats. Illustrative of the various sports that may utilize a mat are yoga, gymnastics, martial arts, and general exercise. Now mats are available in a variety of sizes and shapes. 
         [0003]    Some individuals, for example, the elderly, pregnant women, and individuals with health problems that prevent them from participating in other sports often seek fun, low-impact methods of exercise. However, while these individuals are attracted to exercise, they are discouraged by the pain caused by the exertion of pressure on portions of the body not well configured to take such pressure, such as the knees, elbows, shoulders, hips, pelvis, buttocks, and the head. Additionally, body parts such as the hands and feet, while naturally adapted to support portions of the body&#39;s weight, may nevertheless cause an individual to experience pain when loaded at certain angles, in certain positions, or for long periods of time. Some individuals may thus be precluded from participating in exercise because of pain caused by focusing the body&#39;s weight on certain areas of the body. 
       SUMMARY 
       [0004]    Mats having an additional padded or cushioned portion are disclosed herein. When performing exercises some of the body parts may support the weight of the entire body for an extended period of time. An exercise mat with additional padding in appropriate locations may enhance user comfort, protect against injury, and/or ease strain on body parts that support substantial weight. A user of these mats may rest his/her knees or elbows on the padded portion for additional cushioning of tender joint areas. Further, some users of exercise mats may find that pressure applied to areas such as the hands, shoulders, buttocks, hips, pelvis, feet, and head may cause discomfort and the use of a padded portion is desirable. The exercise mats herein described comprise a substantially planar body portion combined with one or more portions with additional padding. The size, shape, number, and placement of the padded portions may be tailored to the intended use of the exercise mat. The padded portion may also be integrated into the mat or attached and moved at the discretion of the user. Finally, the padded portion may be integrated into the exercise mat between layers of the body portion or alternatively, the padded portion may be attached to an exterior planar surface of the exercise mat.

     DETAILED DESCRIPTION 
       [0014]    One implementation of an exercise mat disclosed herein may comprise a generally rectangular body portion having a substantially uniform thickness and an extra padded portion integrated with the exercise mat. Implementations of exercise mats described herein may be formed in a variety of sizes and shapes and are not limited to a generally rectangular shape. The padded portion when combined with the body portion of the exercise mat provides a greater thickness than the thickness of the body portion of the exercise mat alone resulting in additional cushioning in the area of the padded portion. The padded portions may help support and ease strain on the body, such as while exercising. The exercise mats disclosed may be used for cushioning the body while exercising, but may also be used for cushioning the body while kneeling, such as during gardening or other activities. The exercise mats described herein may be used for many exercises, for example, yoga, pilates, PiYo, weight-lifting, stretching, gymnastics, martial arts, and physical therapy. 
         [0015]    The padded portion of the exercise mat provides padding to cushion more tender areas of the body, such as knees, elbows, and hands during kneeling activities, while the remainder or body portion of the exercise mat may be formed to be thinner to help a user feel more grounded or stable to enhance balance during exercise. For example, during yoga exercises the thinner portions of the exercise mat may be used for holding standing poses while the padded portions of the exercise mat may be used to provide additional cushioning for the knees, elbows, and/or hands during kneeling poses. Additionally, the padded portion may be used to cushion the shoulders, buttocks, hips or the head during exercises wherein the user lays on the exercise mat. For example, during pilates exercises, portions of the user&#39;s hip are often substantially supporting the user&#39;s body and could benefit from additional cushioning. Implementations of exercise mats having additional padded portions may enhance the exercise experience by eliminating the need for people to roll or double-over their exercise mats or to use additional padded exercise mats, cushions, pillows, or blankets, which may slip in relation to the exercise mat. 
         [0016]    Implementations of exercise mats may comprise a padded, cushioned, or thickened portion integrated with a body portion of the exercise mat. The body of the exercise mat may comprise two substantially uniform opposing planar surfaces. During use of the exercise mat, one of the planar surfaces may contact the floor and the other opposing planar surface may be in contact with a person during exercise. The padded portion may be designed such that it extends above/beyond both of the planar surfaces on both sides of the exercise mat. In other embodiments the padded portion may be designed such that it extends above/beyond only one of the planar surfaces on one side of the exercise mat. Additionally, the padded portion of the exercise mat may also have gradually sloped sides so that the padded portion gradually merges into the thinner body portions of the exercise mat. In yet another embodiment, the padded portion may be disposed between layers of the body portion of the exercise mat such that one or both of the substantially uniform opposing surfaces are not planar in the area of the padded portion. The padded portion disposed within the body portion may cause the substantially uniform opposing surfaces to bow outwardly in the area where the padded portion is located. 
         [0017]    The padded portions may be positioned at a number of different locations on the exercise mat and may be formed in a variety of different shapes and sizes. In some exemplary embodiments the padded portion may comprise one portion extending across the width of the exercise mat. In this embodiment the single raised portion may be used to cushion the knees or elbows, for example. In another exemplary embodiment the padded portions may comprise two portions extending across the width of the exercise mat. In this embodiment one portion may be used to cushion the knees and one portion may be used to cushion the elbows or hands, for example. 
         [0018]    In other embodiments exercise mats may be formed with several different padded portions. An exercise mat may include a padded portion positioned near one end of the exercise mat for supporting the head. An exercise mat may also include separate padded portions spaced apart for cushioning the hands or elbows and for cushioning the knees or feet. An exemplary exercise mat for yoga may comprise three padded portions disposed as two portions extending along the length or width of the exercise mat for cushioning the knees/feet and elbows/hands and a third padded portion at one end of the exercise mat for cushioning the head or near the middle of the exercise mat for cushioning the hips, buttocks, and pelvis. 
         [0019]    Implementations of exercise mats disclosed herein may also be designed with padded portions extending across the width of the exercise mat, extending along the length of the exercise mat, or disposed as various shapes (e.g. circles, squares, triangles, bands, etc.) in a number of different locations on the exercise mat. The number and positioning of the padded portions may be determined by the ultimate athletic purpose of the exercise mat to best accommodate or comfort the user of the exercise mat. 
         [0020]    Implementations of exercise mats disclosed herein may be formed of a number of different materials, for example, durable foam, to provide some cushioning while having a high-tack surface to prevent slipping during activity. Other exemplary materials may include cellular vinyl, rubber, open cell foam, bio-cellular foam from soybean or corn plants, bamboo, natural rubbers, polychloroprene, latex, polyvinyl chloride (PVC), jute, polymer environmental resin (PER) plastic, or thermoplastic elastomer (TPE) which contains carbon and hydrogen. Any number of other materials having cushioning and/or elastomeric properties may also be used. In one embodiment, the body portion and the padded portion of the exercise mat may be formed of the same materials. In an alternative embodiment, it may be possible or desirable to use different materials to construct the body portion and the padded portion of the exercise mat. 
         [0021]    Implementations of exercise mats disclosed herein may be formed of a material which is soft enough to provide comfort while having a surface that is tacky enough to prevent slipping or sliding during exercise. The exercise mats may also be formed of a material which is both durable and washable to provide a more hygienic exercise surface. The exercise mats may be thin enough to be rolled and fitted into a bag, such as a yoga bag, or wrapped with a carrying strap. Alternatively, the exercise mats may be folded one or more times and fitted into a bag or wrapped with a carrying strap. The exercise mats may also be formed from toxin-free materials, for example, materials free of phthalate based plasticizers, such as dinoctyl phthalate (DOP) softeners, toluene, Azo dyes, or heavy metals. The exercise mats may be ecologically friendly through manufacture with degradable, biodegradable, and/or recyclable materials and may provide a more health-friendly appeal if made without latex, PVC, and other various chlorides. 
         [0022]    Implementations of exercise mats having padded portions described herein may be formed as single unitary structures or may be formed such that the padded portions may be detachably coupled to/from the body portion of the exercise mat. The exercise mats may be formed by an extruding process, wherein a foam mat may thicken in desired locations to form the padded portion. Alternatively, the exercise mats may be formed in a mold with the body portion and padded portion formed together in the same mold or formed in separate molds and later coupled together. When formed separately, the body portion and padded portion may be formed into an exercise mat by either permanently or detachably coupling the padded portion to the body portion in the desired location. Another way of forming the exercise mat may be to laminate the padded portion between two adjacent layers of the body portion of the exercise mat. More specifically, the body portion of the exercise mat may comprise at least two layers with generally matching planar surfaces joined together through the use of high heat, pressure, and/or adhesives. At least one padded portion may be placed between the layers of the body portion of the exercise mat in desired locations and then sealed in those locations through the laminating process as described above. 
         [0023]    The padded portion may comprise the same material as the body portion of the exercise mat or alternatively it may comprise a different material, for example, cotton, polyester and/or wool batting, down, or ethylene-vinyl acetate (EVA) foam. In one embodiment the padded portion may be integrated with the body portion of the exercise mat. In this embodiment it may be desirable to provide a gradually sloped edge where the padded portion meets the body portion of the exercise mat. The gradually sloped edge portion may help to prevent the user from tripping or stumbling when moving from one area of the exercise mat to another area. Other processes and materials may also be used to form the exercise mats disclosed herein. 
         [0024]    In other embodiments, the padded portion of the exercise mat may be formed separately from the body portion of the exercise mat. The padded portion may be removable from or capable of being detachably coupled to the body portion of the exercise mat. In these embodiments the padded portion may be formed of the same material as that of the body of the exercise mat or may be formed of materials different from that of the body of the exercise mat. The padded portion may be formed as a pillow structure and stuffed with a different material, for example, batting. In one implementation the padded portion may be sized to be received by a pocket located on the body portion of the exercise mat. In another implementation the padded portion may be detachably coupled to an area of the body portion of the exercise mat, for example, with a hook-and-loop fastening mechanism, adhesive materials, belts, or clips. Alternatively, the padded portion may be formed separately from the body portion of the exercise mat and may simply be used in conjunction with the exercise mat. In this embodiment, the exercise mat and the padded portion may have tacky surfaces that operate to keep the padded portion securely in place and prevent slipping or sliding of the padded portion in relation to the exercise mat. 
         [0025]    In some implementations the padded portion may be formed as a hollow area containing a bladder or reservoir which may be filled with a fluid, for example, air, water, or gel. In this implementation a user may inflate the padded portion of the exercise mat with the fluid to the desired thickness and/or firmness via a fluid conduit extending outwardly from the bladder to the exterior of the exercise mat. This fluid conduit may be equipped with a valve or a cap to selectively seal the fluid conduit and the fluid within the bladder. In this implementation a user would also have the option to refrain from inflating the padded portions during certain exercise activities to use the exercise mat as a mat having a substantially uniform thickness. Alternatively, the fluid may be hermetically sealed within the bladder at the time of manufacture. 
         [0026]    Referring now to  FIGS. 1A and 1B , one embodiment of the exercise mat is shown. More specifically, the exercise mat  100  is generally rectangular in shape with a singular padded portion  102  spanning the width of the exercise mat  100  in a position closer to one end of the exercise mat  100  than the other. The padded portion  102  is depicted in  FIGS. 1A and 1B  as fully integrated into the body portion  104  of the exercise mat  100  and incorporates gradually sloped edges  106  to help prevent the user from tripping or stumbling when moving from one area of the exercise mat  100  to another area. In this specific configuration, the padded portion  102  may be utilized for cushioning the user&#39;s hands, elbows, knees, shoulders, buttocks, hips, pelvis, feet, or head depending on the position of the user&#39;s body on the exercise mat  100 . The embodiment of the exercise mat  100  depicted in  FIGS. 1A and 1B  is merely an example of one configuration of the exercise mat  100 .
