1. Field of the Invention
This invention relates to a exercise equipment and, particularly, exercise mats. The exercise mat is made of a material that is both resilient and deformable, and can bias itself against both normal and lateral forces applied thereto.
2. Description of the Related Art
The following descriptions and examples are given as background only.
Numerous types of mats are used in the exercise industry. In general, such mats can accommodate a person, either in the standing or prone position, in order to protect that person against impact from a hard floor surface. Many mats can be rolled up and stored when not in use. Not only can exercise mats protect a person against floor impact, but also shield the floor from sweat and other bacteria absorbed within the mat itself.
Conventional mats are generally not durable enough to withstand excessive repeated impact from a weighted object. In addition, such mats are not resilient enough to bias the object back to its position prior to impact. In many applications, it is important not only to bias the object in the normal force vector direction, but also in a lateral direction so as to keep the object from glancing off the mat and onto the adjacent floor surface.
Therefore, a need exists for an exercise mat that is resilient and durable to excessive repeated impacts (e.g., thousands to possibly hundreds of thousands) and can deform at each impact sufficient to bias the object back toward its original position in the normal and lateral directions.
The problems outlined above are solved by an exercise mat that is designed to have a bottom surface that can securely contact a floor, yet no adhesive backing material is required. The bottom surface can also be secured against a wall if desired. Generally speaking, the front surface can have protrusions. It is desirable that the protusions be circular, and extend hemispherically upward from the front surface. There may be other protrusions associated with written indicia, for example, that can be included on the front surface.
The protrusions can extend as part of the mat material and, therefore, the overall mat including the protrusions and indicia can be of a singular, unibody construction. If so, the overall mat is preferably constructed of a single-molded foam material. In a preferred embodiment, the foam material can be made of ethylene-vinyl acetate or, alternatively, a rubber foaming material can be used in an extruded mold that is fashioned using an upper and lower tool or plates.
According to another embodiment, the protrusions and indicia can be made from a material of different density and resiliency than the mat, and the overall mat can be extruded with apertures to receive the protrusions or indicia which can be secured therein and extended to any desired distance from the front surface depending upon the amount of biasing desired. If advantageous, the protrusions can be adjusted in the field or by the manufacturer. In this fashion, the protrusions and indicia can be changed in accordance with the desired mat functionality or aesthetics. Alternatively though not preferred, the end user can manually cut-out apertures if, for example, multiple alternative designs are desired for the protrusions and indicia.
It is desirable that the protrusions be circular in a hemispherical shape. The hemispherical shape can have a rounded or flattened upper portion depending on the user's preference and mat functionality. A circular protrusion is preferred so that the angle of lateral impact is equally resilient in all directions. For example, a square protrusion would give a greater lateral resilience in one direction than another.
The outer dimensions of the mat can be circular, square, or rectangular. Regardless of the outer dimensions, it is desirable that the innermost region of the mat have circular protrusions and the outermost region of the mat can have indicia, such as alphabetic characters or other designs, or rectangular protrusions. Since a weighted object will most likely strike the innermost portion of the mat, the circular protrusions provide a greater benefit than the non-circular protrusions at the outermost region, not only with regard to any lateral bias provided by the circular shape, but also to the weighted object itself.
According to one embodiment, an exercise mat is provided. In this embodiment, the mat can be circular. The exercise mat comprises indicia on a front surface of the mat which can extend in an arcuate pattern proximate to an edge of the mat. A center protrusion is also provided proximate to a center of the front surface of the mat. A plurality of substantially circular protrusions are also provided which extend from the front surface of the mat between the edge of the mat and the center protrusion. The indicia preferably comprises at least two alphabetic characters spaced from each other. In one embodiment, the alphabetic characters can extend radially outward toward the edge of the mat. The circular protrusions can be located at predetermined distances from each other that can vary depending on their proximity to the center protrusion and the indicia. Depending on the orientation of the mat, the indicia and circular protrusions can provide opposing vertical and horizontal forces when impacted by a weighted object. The horizontal force can be a lateral force to provide frictional resistance when impacted by a weighted object, such as an exercise ball or foot.
According to another embodiment, an exercise mat is provided. In this embodiment, the mat can be rectangular or square. The exercise mat can include indicia on a front surface of the mat which extends in a substantially straight direction proximate to an edge of the mat. The exercise mat can further include rectangular protrusions on the front surface proximate each edge of the mat as well as circular protrusions proximate the center of the mat that can be surrounded by the rectangular protrusions.
Other objects and advantages of the invention will become apparent upon reading the following detailed description and upon reference to the accompanying drawings in which:
While the invention is susceptible to various modifications and alternative forms, specific embodiments thereof are shown by way of example in the drawings and will herein be described in detail. It should be understood, however, that the drawings and detailed description thereto are not intended to limit the invention to the particular form disclosed, but on the contrary, the intention is to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention as defined by the appended claims.
The following description of various embodiments of exercise mats is not to be construed in any way as limiting the subject matter of the appended claims.
Also illustrated is a plurality of protrusions 20 which are preferably raised or extended from the front surface of mat 10 and are spaced from each other. Protrusions 20 are preferably circular in shape having a hemispherical upper surface, according to one embodiment. While many protrusions 20 can exist near design features 12/14 and indicia 16/18, it is preferred that most of the protrusions 20 occur in the region between a center protrusion 22 and indicia 16/18. By congregating protrusions 20 in this fashion, the majority of strikes upon mat 10 are accommodated by protrusions 20 having a hemispherical upper dimension and contour. Having protrusions 20 in a circular, hemispherical contour, lends to their omni-directional biasing features and allows a striking object, such as a weighted ball, to return to its original position after being thrown by a person standing above the mat, for example. Avoiding sharp edges helps eliminate any non-consistent frictional forces applied to an object in the lateral direction, regardless of the direction in which the object is applied to mat 10. Sharp edges, such as corners or certain letters of the alphabet contained in design features 12/14 or indicia 16/18, could prevent the object from returning to its original position.
Center protrusion 22 is also preferably circular in shape with an inner dimension 24 that can vary in size. According to an alternative embodiment, center protrusion 22 can also vary in size. Inner dimension 24 can preferably form a design, such as that shown in
Preferably, mat 10, design features 12/14, indicia 16/18, protrusions 20, center protrusion 22, and inner dimension 24 are all formed in a single molded or extruded process within the confines of a tool that stamps a molded material to form a unibody construction. The material is preferably an EVA material, such as ethylene-vinyl acetate or any suitable rubber foaming material which has an elasticity and is resilient to many thousands of strikes by an object, such as a weighted ball, yet is deformable at each strike. The various features formed on the front surface of mat 10 provide both normal and lateral biasing against any object thrown or applied against mat 10.
According to an alternative embodiment as illustrated in
