Patent Application
20230173333
This application relates to the field of mats, and more specifically, to exercise mats and the like, and methods of making same.
Exercise mats, pads and cushions are often used during a variety of exercise activities that are conducted on a floor surface, such as yoga, Pilates and other training workouts. Many existing exercise mats are made of rubber, foam or other cushioning materials to provide comfort and cushioning to a user over hard flooring. For example, a user may position an exercise mat on a hard floor surface to provide a more comfortable experience during various yoga poses or stretching exercises.
Most exercise mats, such as yoga mats, are designed to be used at home without shoes. Such mats are not designed to be used with equipment (e.g. weights, shoes, etc.) or in different workouts where mats with abrasion resistant surfaces that support lateral training movements are required. These exercise mats may breakdown through use in more varied workouts with equipment. Furthermore, mats may slip or slide on a floor surface or the user may slip on the mat during lateral training movements.
Thus, there remains a need for exercise mats that are fully supportive to the user's body, and textured to support lateral movements and avoid slipping.
In various embodiments, the present disclosure provides exercise mats incorporating areas of increased friction as compared to other areas of the exercise mat, the areas generally corresponding to sections of a top surface of the exercise mat where there is the most contact between the user and the exercise mat during use.
In one aspect, the present disclosure provides an exercise mat comprising: a top layer, at least two textured gripping zones formed on an upper surface of the top layer, the at least two textured gripping zones providing different levels of friction when a body is in sliding contact with the at least two textured gripping zones of the upper surface of the top layer, and a bottom layer joined to the top layer, wherein a friction level of a first textured gripping zone in sliding contact with the body is lower than a friction level of a second textured gripping zone in sliding contact with the body.
In various embodiments, the at least two textured gripping zones are joined by a seamless transition.
In various embodiments, the second textured gripping zone is positioned closer to one or more edges of the exercise mat.
In various embodiments, the exercise mat further comprises at least one additional textured gripping zone. For example, the at least one additional textured gripping zone may be positioned between the first and the second textured gripping zones. The at least one additional textured gripping zone may provide a friction level greater than the first textured gripping zone when in sliding contact with the body, and smaller than the second textured gripping zone when in sliding contact with the body. Alternatively, the friction level increases gradually from the first textured gripping zone toward the second textured gripping zone.
In various embodiments, the at least two textured gripping zones, including the at least one additional textured gripping zone, on the top layer of the exercise mat may comprise a plurality of raised surfaces extending upwards from the upper surface. For example, the textured gripping zones may comprise a plurality of semi-spheres, a height of the semi-spheres in the second textured gripping zone being greater than a height of the semi-spheres in the first textured gripping zone. Alternatively or in addition, a diameter of the semi-spheres in the second textured gripping zone may be greater than a diameter of the semi-spheres in the first textured gripping zone.
In various embodiments, the top layer comprises a polyvinyl butyral. For example, the top layer may comprise a polyvinyl butyral foam.
In various embodiments, the bottom layer comprises a polyvinyl butyral. For example, the bottom layer may comprise a polyvinyl butyral foam.
In various embodiments, a face surface of the bottom layer is at least partially textured, such as over the entire face surface, to provide friction between the face surface and a surface against which the mat is placed to prevent slippage of the exercise mat on the surface.
In various embodiments, the exercise mat further comprises a middle layer between the top layer and the bottom layer. For example, the middle layer may comprise a thermoplastic elastomer material.
In various embodiments, the top layer may also comprise at least one wicking agent, at least one antimicrobial agent, or both.
In addition to the aspects and embodiments described above, further aspects and embodiments will become apparent by reference to the drawings and study of the following detailed description.
Throughout the drawings, reference numbers may be re-used to indicate correspondence between referenced elements. The drawings are provided to illustrate example embodiments described herein and are not intended to limit the scope of the application. Sizes and relative positions of elements in the drawings are not necessarily drawn to scale. For example, the shapes of various elements and angles may be not drawn to scale, and some of these elements may be arbitrarily enlarged and positioned to improve drawing legibility.
In the following description, details are set forth to provide an understanding of the application. In some instances, certain structures, techniques, and methods have not been described or shown in detail in order not to obscure the application.
In the context of the present disclosure, various terms are used in accordance with what is understood to be the ordinary meaning of those terms.
Disclosed embodiments include exercise mats and methods of making same. In various embodiments, the disclosure provides exercise mats that may be used in a fitness studio environment or at a user's home, either inside or outside, where shoes, weights and/or other equipment are being used during exercise. In various embodiments, the exercise mat may be particularly suitable for high intensity and/or high impact work-outs involving lateral training movements. During such movements, users are more prone to slipping, in addition to the mat slipping on a floor surface. The exercise mats as described herein address these issues. The exercise mats as disclosed herein are for placement on a flat surface by a user to provide cushioning, grip, support, stability or any combination thereof, allowing the user to more easily and effectively perform yoga and/or other exercises, including high intensity training and other exercises involving lateral training movements.

In various embodiments, the exercise mat 10 further comprises at least one additional textured gripping zone 22. The at least one additional textured gripping zone 22 may be positioned between the first 14 and second 16 textured gripping zones. In such embodiments, the at least one additional textured gripping zone 22 provides a friction level greater than the first textured gripping zone 14 when in sliding contact with the body and smaller than the second textured gripping zone 16 when in sliding contact with the body. In some embodiments, the at least one additional textured gripping zone 22 may alternate with the second textured gripping zone 16 in any pattern. For example, the at least one additional textured gripping zone 22 may alternate concentrically with the second textured gripping zone 16, as shown in
As shown in
The at least two textured gripping zones 14 and 16, as well as the at least one additional textured gripping zone 22, may comprise a plurality of semi-spheres 24, as shown in
In various embodiments, the top layer 12 and/or the bottom layer may comprise a polyvinyl butyral, which may be recycled and/or used polyvinyl butyral. By being made of polyvinyl butyral, the exercise mats as disclosed herein may have higher abrasion resistance as compared to other mats. For example, the top layer 12 and/or the bottom layer comprise a polyvinyl butyral foam, such as a closed cell polyvinyl butyral foam, making the mat easier to clean and/or more stain resistant as compared to previous mats.
In various embodiments, a face surface of the bottom layer of the exercise mat may be at least partially textured to provide increased friction between the face of the bottom layer of the exercise mat and a surface against which the exercise mat is placed to decrease or prevent slippage of the exercise mat on the surface during use.
In various embodiments, the exercise mats as disclosed herein further comprise a middle layer between the top layer 12 and the bottom layer. For example, the middle layer may comprise a thermoplastic elastomer material. For such embodiments, the exercise mat 10 may be prepared by joining the top layer 12 and the middle layer, and then the at least two textured gripping zones are embossed on the top surface 18 of the top layer 12 as described in further detail below.
In various embodiments, a thickness of the exercise mats as disclosed herein may be between about 0.5 mm and about 6.5 mm, between about 0.5 mm and about 4.5 mm, between about 0.5 mm and about 3.5 mm, or any thickness therebetween. In various embodiments, the exercise mat has a thickness of about 6.5 mm.
In various embodiments, the exercise mats as disclosed herein may weight about 3.5 lbs.
In various embodiments, the exercise mats as disclosed herein have sufficient flexibility such that they can be rolled and/or folded for transport and/or storage.
The exercise mats as disclosed herein may be prepared by mixing a combination of ingredients, such as, for example, polyvinyl butyral, triglycol dioctate, stearic acid and water, as well as other optional additives such as foaming agents, fillers, plasticizing agents and the like. The materials may be mixed, melted and blended in an extruding machine or mixing machine. The exercise mats may then be formed through compression molding, using a mold comprising the at least two textured gripping zones for the top layer 12, and a separate mold for the bottom layer. In various embodiments, the top layer 12 may further be treated with an antimicrobial agent, such as, for example, a silver-based antimicrobial agent and/or 3-trimethoxy propyl dimethyl octadecyl ammonium chloride.
The top layer 12 and the bottom layer are then joined, with an optional middle layer therebetween. For example, the layers may be joined using an adhesive or a bonding technique. In various embodiments, the layers may have thermoplastic bonding properties that cause adjacent layers to bond with one another when heated. Alternatively, the layers may be bonded using adhesives and/or mechanical connections. In addition, any combination of these methods or any other methods known to those of ordinary skill in the art may be used.
In various embodiments, the exercise mat 10 may be made using a vacuum embossing machine. The vacuum embossing machine may include a mold plate having an embossed top surface that has a female version of the textured gripping zones embossed thereon to form a male version of the textured gripping zones on the exercise mat 10. The top layer 12 of the exercise mat 10 is attached to the middle layer, the middle layer comprising a thermoplastic elastomer material. The mat formed from joining the top and middle layers is cut to a desired size and shape, and is positioned on the mold plate having the embossed top surface, with the polyvinyl butyral side of the top layer facing the embossed top surface texture of the mold plate. The mold plate is inserted into a vacuum embossing machine and the mat is heated, for example, for about two minutes at a temperature of about 170° C., or alternatively, for about 1 to about 15 minutes at a temperature of about 120° C. to about 200° C., and with a suction pressure provided by the embossing machine such that the temperature and suction provided by the vacuum embossing machine softens the thermoplastic elastomer of the middle layer and conforms it to the textured gripping zones of the mold plate to form a corresponding surface texture through the polyvinyl butyral side of the top layer 12. The mat can then be cooled, and the bottom layer is attached to form the exercise mat 10.
Following production, the exercise mats as disclosed herein may comprise about 70% or more polyvinyl butyral, about 25% or more triglycol dioctate, about 3.5% or less stearic acid, and about 1.5% or less water.
These examples illustrate various aspects of the invention, evidencing different embodiments of the exercise mats as disclosed herein.
