The protrusions may be tapered and rounded at their distal ends to minimize carpet damage. The system may include multiple groups of protrusions arranged in repeating patterns across the mat's surface, optimizing grip and stability. The system provides an effective solution for stabilizing chair mats on carpeted floors while protecting the carpet from wear and damage over time.

Description

[0001] A portion of the disclosure of this patent document contains material that is subject to copyright protection. The copyright owner has no objection to the reproduction of the patent document or the patent disclosure, as it appears in the U.S. Patent and Trademark Office patent file or records, but otherwise reserves all copyright rights whatsoever.BACKGROUND

[0002] The present invention relates generally to chair mats, specifically those designed for use on carpeted flooring. More particularly, the present disclosure pertains to a novel gripper system intended to secure the chair mat in place while minimizing damage to the underlying carpet.

[0003] Chair mats are commonly used in offices, homes, and various work environments to protect flooring surfaces, particularly carpets, from the wear and tear caused by the movement of office chairs. A critical feature of chair mats is their ability to remain in place while in use, preventing slipping and shifting. To achieve this stability, traditional chair mats typically incorporate carpet grippers with cone or spike-shaped elements that penetrate carpet fibers, providing the necessary friction to hold the mat securely in position.

[0004] While cone and spike-shaped grippers are effective at providing grip, they present several significant drawbacks. First, the sharp points of these grippers can cause extensive damage to carpet fibers. As the grippers penetrate the carpet to achieve friction, they create punctures and tears in the fibers, leading to visible wear and degradation of the carpet. Over time, this damage can not only diminish the aesthetic appearance of the carpet but can also contribute to a reduction in the carpet's overall durability, significantly shortening its lifespan.

[0005] Furthermore, the penetration of these sharp grippers into the carpet often results in increased friction between the grippers and the carpet backing, which can cause further stress on the carpet's structure. This can lead to permanent indentations or even the detachment of the carpet's backing layer, further compromising the integrity of the flooring surface.

[0006] In addition to the issues caused by the physical damage to carpets, traditional cone or spike grippers can also pose challenges during the use and handling of the chair mat itself. The sharp points can create safety hazards, especially during installation or repositioning of the mat. There is an increased risk of injury from handling a mat with sharp or protruding elements, as users may inadvertently come into contact with the pointed grippers. Additionally, the pointed grippers can also complicate the manufacturing process, as misalignment of the grippers during production can lead to inconsistencies in performance or efficiency.

[0007] Thus, while cone and spike-shaped carpet grippers have been the standard in chair mats, their potential to cause damage to carpets, pose safety risks, and complicate the manufacturing process highlights the need for a more effective, carpet-friendly alternative to traditional gripper designs.BRIEF SUMMARY

[0008] In view of at least some of the above-referenced problems in conventional chair mats, an exemplary object of the present disclosure may be to provide a new and improved floor mat retention system to secure the floor mat in place while minimizing damage to the underlying carpet. The disclosure is aimed at improving the “anti-slip” properties of chair mats by providing increased lateral resistance to carpet fibers, without the need for deep penetration or sharp elements such as traditional cone or spike grippers. By eliminating sharp points and reducing the risk of carpet degradation, the disclosure enhances both the safety and durability of chair mats, offering a more efficient and carpet-friendly alternative to existing designs. Additionally, the disclosure addresses manufacturing challenges associated with traditional gripper systems, improving handling, use, sizing, and overall product performance.

[0009] The system may feature elongated, tapered, and rounded protrusions that extend from the lower surface of the mat to provide lateral resistance, effectively anchoring the mat without the need for sharp carpet grippers. These protrusions are arranged in specific radial patterned groupings, with varying angles between the protrusions to optimize grip and stability. The design ensures that pressure is evenly distributed across the mat, reducing the risk of carpet penetration and wear. Additionally, the system may feature repeating patterns of protrusions across rows and columns, improving handling, safety, and durability. The system offers an effective solution for maintaining and improving mat stability while preserving carpet integrity, making it a superior alternative to traditional carpet gripper designs.

[0044] Referring to FIGS. 1-2 and 9, a floor mat retention system 100 is provided. The floor mat retention system may include a mat 110 and at least one group of elongated protrusions 120. The mat 110 may also be referred to herein as a floor mat 110 or a chair mat 110. The mat 110 may include an upper surface 112 and a lower surface 114. The at least one group of elongated protrusions 120 may extend from the lower surface 114 of the mat 110. The floor mat retention system 100 may specifically be designed to improve the anti-slip properties of chair mats used on carpeted surfaces while reducing potential carpet damage caused by traditional grippers.

[0045] Referring to FIGS. 3-6, additional views of the at least one group of elongated protrusions 120 are shown. In certain optional embodiments, as further discussed below, the at least one group of elongated protrusions 120 may include at least two elongated protrusions which may be angled relative to each other. In other optional embodiments, as illustrated herein, the at least one group of elongated protrusions 120 may include a first elongated protrusion 122, a second elongated protrusion 124, and a third elongated protrusion 126. As illustrated in FIG. 6, the second elongated protrusion 124 may be angled at a first angle 130 relative to the first elongated protrusion 122. The third elongated protrusion 126 may be angled at a second angle 132 relative to the second elongated protrusion. The third elongated protrusion 126 may be angled at a third angle 134 relative to the first elongated protrusion 122. In certain optional embodiments, the first angle 130 may be greater than the second angle 132. In other optional embodiments, the third angle 134 may be greater than the second angle 132. In further optional embodiments, the first angle 130 may be equal to the third angle 134. In certain optional embodiments, the first angle may be about one hundred thirty-five (135) degrees. In other optional embodiments, the second angle may be about ninety (90) degrees. These angles may be changed in other optional embodiments such that the first, second, and third angles 130, 132, 134 add up to three hundred sixty (360) degrees. The arrangement of the elongated protrusions ensures the mat maintains its stability across different areas of the carpet, optimizing grip and minimizing potential carpet damage. As illustrated in FIG. 3, the elongated protrusions offer increased lateral resistance (e.g., force arrows) against carpet fibers and enhance the mat's stability without sharp, invasive carpet penetration.

[0046] Each of the first, second, and third elongated protrusions 122, 124, 126 may be disposed around and extend radially relative to a center point 150. Each of the first, second, and third elongated protrusions 122, 124, 126 may include a length 140 defined radially from the center point 150. Each of the first, second, and third elongated protrusions 122, 124, 126 may be spaced apart from the center point 150 by a radial dimension 152 less than the length 140 of each of the first, second, and third elongated protrusions 122, 124, 126. The length 140 may be defined proximate to the lower surface 114 of the mat 110. The design of the protrusions distributes force evenly across the mat's surface, preventing localized pressure that could lead to carpet damage over time.

[0047] Each of the first, second, and third elongated protrusions 122, 124, 126 may include a height 142 and a width 144, each defined perpendicularly relative to the length 140. The width 144 may be defined proximate to the lower surface 114 of the mat 110. The height 142 may be defined between the lower surface 114 of the mat 110 and a distal end 146 of the respective first, second, or third elongated protrusion 122, 124, 126. In certain optional embodiments, the height 142 may be less than the length 140. In other optional embodiments, the height 142 may be greater than or equal to the length 140. In certain optional embodiments, the width 144 may be less than the length 140. In other optional embodiments, the width 144 may be greater than or equal to the length 140. In certain optional embodiments, the width 144 may be less than the height 142. In other optional embodiments, the width 144 may be greater than or equal to the height 142.

[0048] In certain optional embodiments, as illustrated in FIGS. 4-5, the distal end 146 of each of the first, second, and third elongated protrusions 122, 124, 126 may be rounded, for example, at the corners. In further optional embodiments, each of the first, second, and third elongated protrusions 122, 124, 126 may be tapered towards the distal end 146 thereof. The tapering and rounded corners ensures that the protrusions 120 do not dig deeply or sharply into the carpet, reducing long-term wear and improving the durability of both the mat 110 and the carpet.

[0049] Referring to FIGS. 7-8, the at least one group of elongated protrusions 120 may comprise a first group of elongated protrusions 120A and a second group of elongated protrusions 120B. In certain optional embodiments, the first group of elongated protrusions 120A may be angled relative to the second group of elongated protrusions 120B. In further optional embodiments, the first group of elongated protrusions 120A may be positioned adjacent to the second group of elongated protrusions 120B. As discussed below, these groups can be arranged in repeating patterns to optimize grip and stability across the mat's surface.

[0050] In certain optional embodiments, the at least one group of elongated protrusions 120 may comprise a plurality of groups of elongated protrusions. As such, the at least one group of elongated protrusions 120 may also be referred to herein as a plurality of groups of elongated protrusions 120. The layout of these groups can be further optimized to ensure uniform anti-slip performance across the mat 110, as further discussed below.

[0051] As illustrated in FIG. 7, the floor mat retention system 100 may include a first pair of groups 160 of the plurality of groups of elongated protrusions 120 which may be disposed at a first group angle 161 relative to each other. The floor mat retention system 100 may further include a second pair of groups 162 of the plurality of groups of elongated protrusions 120 which may be disposed at a second group angle 163 relative to each other. The floor mat retention system 100 may further include a third pair of groups 164 of the plurality of groups of elongated protrusions 120 which may be disposed at a third group angle 165 relative to each other. In certain optional embodiments, the first group angle 161 may be ninety (90) degrees. In other optional embodiments, the first group angle 161 may be greater than or less than ninety (90) degrees. In certain optional embodiments, the second group angle 163 may be one hundred eighty (180) degrees. In other optional embodiments, the second group angle 163 may be greater than or less than one hundred eighty (180) degrees. In certain optional embodiments, the third group angle 165 may be ninety (90) degrees. In other optional embodiments, the third group angle 165 may be greater than or less than ninety (90) degrees.

[0052] In certain optional embodiments, the first pair of groups 160 may define a repeating pattern along a first row 180 (as shown in FIG. 8), the second pair of groups 162 may define a repeating pattern along a second row 182, and the third pair of groups 164 may define a repeating pattern along a third row 184. In further optional embodiments, the floor mat retention system 100 may include additional pairs of groups of the plurality of groups of elongated protrusions 120 and additional rows. In still further embodiments, the pairs of groups may repeat as additional rows are added to form a pattern vertically (e.g., along a column). This arrangement ensures uniform performance no matter where the user places or rolls their chair on the mat.

[0053] As illustrated in FIG. 8, the floor mat retention system 100 may include a first row of groups 170 of the plurality of groups of elongated protrusions 120 including a first row repeating pattern 171. Each group of elongated protrusions of the first row repeating pattern 171 may be rotated relative to a horizontally adjacent group of elongated protrusions, for example, as discussed above with regard to the first pair of groups 160. The floor mat retention system 100 may further include a first column of groups 172 of the plurality of groups of elongated protrusions including a first column repeating pattern 173. Each group of elongated protrusions of the first column repeating pattern 173 may be rotated relative to a vertically adjacent group of elongated protrusions, for example, by forty-five (45) degrees, ninety (90) degrees, one hundred thirty-five (135) degrees, one hundred eighty (180) degrees, or the like.

[0054] In certain optional embodiments, the floor mat retention system 100 may further include a second row of groups 174 of the plurality of groups of elongated protrusions 120 including a second row repeating pattern 175 different than the first row repeating pattern 171. In further optional embodiments, the floor mat retention system 100 may further include a second column of groups 176 of the plurality of groups of elongated protrusions 120 including a second column repeating pattern 177 different than the first column repeating pattern 173. In further optional embodiments, the floor mat retention system 100 may further include any number of additional rows or columns of groups of the plurality of groups of elongated protrusions 120.

[0055] As shown in FIG. 9, the mat 110 is designed to be cut into various sizes to meet specific requirements, such as first mat size 110A, second mat size 110B, third mat size 110C, and others. This careful design may prevent any ‘cut-through’ of individual grippers during the stamping process, ensuring that each mat maintains its integrity and functionality, regardless of the size or shape it is cut into. By doing so, the mat remains effective in its grip while retaining a clean and precise edge, ensuring longevity and user satisfaction.
