1. Field of the Invention
This invention relates to athletic and/or protective surface mats for participating in various activities including wrestling, martial arts, tumbling and cheerleading, which may take the form of wrestling mats, training mats, tumbling mats and carpet, and more particularly, a system and method of interlocking sections of such mats.
2. Description of Prior Art Including Information Disclosed Under 37 CFR 1.97 and 1.98
Participants in athletic activities use mats for protection. If the mat is provided in multiple sections, as it often is for easy storage and shipping, the sections need to be connected together before use. The standard connecting devices used for this purpose have been tape and hook and loop fastener strips (i.e. Velcro®).
However, tape is expensive and must be replaced regularly. Hook and loop strips are not easy to clean, do not lay flat and form an abrasive edge along the sides of the mat sections which the hook and loop strips attach together. Further, connecting and disconnecting both tape and hook and loop strips cause stress on the mat surface.
Accordingly, there is a need for a system and method of interlocking sections of athletic or other protective surface mats which forms a continuing connecting surface which is resilient and which attaches the mat sections to each other securely but which permits the mat sections to be easily and quickly attached together and detached from each other. Further, the interlocking closure should permit easy cleaning and create a seal which prevents liquids and particulate matter from being received between the sides of the interlocked mat sections. The system should be relatively inexpensive to fabricate and mount securely to the mat sections. It should also permit the mat sections to be connected together using a roller or similar mechanical pressure applying device.
The present invention employs a zipper-type or rubber/plastic snap strip type closure device to interlock the sides of the mat sections together. The closure device creates a continuous surface across the top of the mats. It is fabricated of smooth, resilient material so as to create a surface similar to the surface of the mat sections. The closure device can extend either horizontally or vertically along the top surface or side surface of the mat section. The closure device is liquid proof and prevents spills and other materials from penetrating below the surface of the closure sections. Further, the closure is easily cleaned because it is liquid proof.
The mats can be fabricated to have a foam or protective core, (such as rubber nitrile foam, polyethylene foam, or other types of resilient material) and can be formed of a single or multiple layers. The surface of the mat can be vinyl, carpet or any other suitable resilient surface. The connecting device may have a relief channel.
The preferred embodiment of the present invention is disclosed herein as employing a MaxiGrip® plastic zipper-type closure available from ITW MaxiGrip of Somerset, N.J. to interlock the mat sections. However, other zipper-type plastic closures available from other sources may function adequately as well.
In accordance with one aspect of the present invention, a system is provided for interlocking first and second mat sections. The system includes a resilient closure strip for interlocking the mats sections. Each of the mat sections has a surface. A layer of reinforced vinyl scrim is situated on the surface of each of the mat sections. The closure strip includes first and second closure members. Each of the closure members has an interengaging portion and a substantially planar connecting portion. The connecting portion of the first closure member is mounted on the first mat section with the interengaging portion thereof in a given orientation. The connecting portion of the second closure member is mounted on the second mat section with the interengaging portion thereof in an orientation substantially opposite to the orientation of the interengaging portion of the first closure member. At least a portion of the interengaging portion of the second closure member extends beyond the surface such that the interengaging portions of the first and second closure members align and can be interengaged when the mat sections are situated in side-by-side relation. A coating of poly-vinyl paint is situated over said first and second closure members and said reinforce vinyl scrim layer.
The system also includes a hand-held roller adapted to apply a downward force on the aligned interengaging portions to interengage the interengaging portions.
In accordance with another aspect of the present invention, a method is provided for interlocking first and second mat sections using a resilient closure strip including first and second closure members, each of the closure members having an interengaging portion and a connecting portion. The method includes the steps of: applying a layer of reinforced vinyl scrim on a surface of each of the mat sections mounting the connecting portion of the first closure member on the surface of the first mat section with the interengaging portion thereof in a given orientation; mounting the connecting portion of the second closure member on the surface of the second mat section with the interengaging portion thereof in an orientation substantially opposite to the orientation of the interengaging portion of the first closure member and at least a portion of the interengaging portion thereof extending beyond the surface to which the second closure member is mounted; locating the first and second mat sections in side-by-side relation such that the interengaging portions of the first and second closure members align; applying a downward force on the aligned interengaging portions of the first and second closure members causing the aligned interengaging portions interengage to interlock the first and second mat sections; and coating the first and second closure members and the reinforced vinyl scrim layer on the surface of each of the first and second mat sections with poly-vinyl paint.
The method also includes applying a downward force on the aligned interengaging portions using a hand-held roller.

To these and to such other objects that may hereinafter appears, the present invention relates to a system and method for interlocking athletic or other protective surface mats as described in detail in the following specification and recited in the annexed claims, taken together with the accompanying drawings, in which like numerals refer to like parts and in which:
As depicted in
Each closure member includes an interengaging portion 10a, 12a, and a generally planar connecting portion 10b, 12b extending outwardly from the interengaging portion. Preferably, the interengaging portion and the connecting portion of each closure member are integral and extruded or otherwise formed together as a single piece.
The present invention is illustrated with a MaxiGrip® plastic zipper-type closure available from ITW MaxiGrip of Somerset, N.J. to interlock the mat sections. However, other zipper-type or snap type resilient closures may function adequately as well.
Closure members 10, 12 are oppositely oriented and mounted to the top of mat sections 14, 16, respectively. When properly aligned, the interengaging portions 10b, 12b of the closure members can be engaged, as seen in
When the closure members 10, 12 are interengaged, the closure creates a substantially continuous surface across the top of the interlocked mat sections 14, 16. The closure members are fabricated so as to provide a surface similar to the top surface of the mat sections 14, 16.
Closure A can extend either horizontally along the top surface 18 of the mat sections (as illustrated) or vertically along the side surfaces 20 of the mat sections. When the closure members are interengaged, liquid proof seal is created which prevents spills of liquid and particulate materials from penetrating below the surface of the closure and entering between the sides 20 of the interlocked mat sections 14, 16. The closure can be easily cleaned because it is liquid proof.
Mat sections 14, 16 can be fabricated to have a foam or protective core, (such as rubber nitrile foam, polyethylene foam, or other types of resilient material) and can be formed of a single or multiple layers. Each mat section 14, 16 includes a body 14a, 14b with a top surface 18 and a side surface 20. A thin layer of reinforced scrim 22 is applied to the top surface 18 of each of the mat section.
The bottom surface of the connecting portion 10b of closure member 10 is fixed to the scrim layer 22 on the top surface 18 of mat section 14 to secure the closure member to the mat section. Similarly, the bottom surface of connecting portion 12b of closure member 12 is fixed to the scrim layer 22 on top surface 18 of mat section 16 to secure the closure member to the mat section.
The connecting portions of the closure members are permanently fixed to the scrim layer on top of the respective mat sections. This can be accomplished by sonic welding, adhesive or other conventional method which does not adversely affect the materials of which the closure members, scrim layer and mat sections are made.
As best seen in
Further, closure member 10 is positioned relative to mat section 14 such that the unattached side of interengaging portion 10a of closure member 10 is substantially co-extensive with the plane of side surface 20 of mat section 14. By way of contrast, closure member 12 is positioned relative to mat section 16 such that interengaging portion 12a of closure member 12 extends beyond the plane of side surface 20 of mat section 16. This permits the interengaging portions 10a, 12a to align when the mat sections 14, 16 are placed in side-by-side relation.
Preferably, a continuous coating 24 of poly-vinyl paint is provided over the exposed surface of each of the closure members 10, 12 and the reinforce vinyl scrim layer 22 of the mat sections. Coating 24 may be applied before or after the mat sections are interlocked. Coating 24 is preferably sprayed onto the surfaces to provide a thin, uniform, protective layer.
As noted previously, closure members 10, 12 are mounted on mat sections 14, 16 in opposite orientations and are located on the mat sections such that interengaging portions 10a, 12a are aligned when the mat sections are in side-by-side relation. That permits the mat sections to be interlocked by simply applying a downward force on the interengaging portions from above.
While the downward interlocking force could be applied manually to interengage the closure members, a hand-held roller, such as illustrated in
The interlocked mat sections can be detached by pull mat 16 upwardly relative to mat section 14 such that interengaging portion 12a is no longer interengaged with interengaging portion 10a. However, as long as the interengaging portions of the closure members are interengaged, a secure, liquid sealed connection is maintained between the mat sections and there is a substantially continuous smooth surface created by the interlocked mat sections.
In use, the first and second mat sections are interlocked using a resilient closure strip including first and second closure members, each of the closure members having an interengaging portion and a connecting portion. A layer of reinforced vinyl scrim is applied on a surface of each of the mat sections. The connecting portion of the first closure member is mounted on the surface of the first mat section with the interengaging portion thereof in a given orientation. The connecting portion of the second closure member is mounted on the surface of the second mat section with the interengaging portion thereof in an orientation substantially opposite to the orientation of the interengaging portion of the first closure member. At least a portion of the interengaging portion of the second closure member extends beyond the surface to which the second closure member is mounted. The first and second mat sections are located in side-by-side relation such that the interengaging portions of the first and second closure members align. A downward force is applied on the aligned interengaging portions of the first and second closure members causing the aligned interengaging portions interengage to interlock the first and second mat sections. The first and second closure members and the reinforced vinyl scrim layer on the surface of each of the first and second mat sections are coated with poly-vinyl paint.
In the preferred embodiment, the downward force is applied on the aligned interengaging portions using a hand-held roller.
While only a single preferred embodiment of the present invention has been disclosed for purposes of illustration, it is obvious that many modifications and variations could be made thereto. It is intended to cover all of those modifications and variations which fall within the scope of the present invention, as defined by the following claims.
