Definitions
- the present invention relates generally to selectively attachable floor coverings, and more particularly to a selectively attachable mat capable of withstanding frequent laundering and to a method of making the same.
- mats are well known in the prior art for use at entrance ways of commercial buildings to collect dirt and water tracked into the building. Accordingly, mats prevent permanent floor coverings, such as carpets, that cannot be easily cleaned or replaced from becoming heavily soiled.
- mats After a period of use, mats become saturated with dirt and water and must be replaced with a clean mat. Typically, mats are replaced after a predetermined period of use, such as one week.
- the mat is commercially launderable, and thus reusable.
- Commercially laundering is abusive to mats because of the water temperature and the detergents necessarily involved. Consequently, a mat may crinkle, shrink or even be destroyed after only a few cycles of use and laundering.
- mats have been constructed in the prior art with a rubber backing that provides support for the carpet portion of a mat. Besides support, the rubber backing also provides an excellent cushion for the mat during use.
- a problem with rubber backed mats is providing a system for fastening such a mat to the floor.
- the fastening system should be inexpensive and able to withstand frequent commercial laundering of the mat.
- the system should hold the mat firmly in place, but allow the mat to be easily removed and replaced. Without such a fastening system, the mat is subject to being inadvertently pushed and sliding out of position. Additionally, the mat may slide out from under a user and cause a slip and fall accident.
- a rubber backed mat needs to be fastened to the floor to prevent such movement.
- the problem with the use of fastening systems on rubber backed mats is getting a fastener to adhere to the rubber backing in a manner that can withstand frequent commercial laundering. In this regard, adhesives break down after only a couple cycles of commercial laundering.
- Alternative methods of attachment, such as sewing or ultrasonic welding are expensive and thus do not provide an adequate solution to the problem.
- the fastening system should be inexpensive and able to withstand frequent commercial laundering of the mat. Additionally, the fastening system should hold the mat firmly in place, but allow the mat to be selectively removed with ease for laundering.
- the present invention provides a solution to solving the problems in the art described above by providing a selectively attachable floor covering capable of withstanding frequent laundering and a method of making the same.
- the floor covering is a mat including a rubber base and one or more fasteners.
- Each fastener comprises selectively attachable material extending into the rubber base for permanent attachment therewith and selectively attachable material protruding from the rubber base for selective attachment with a mating fastener on the floor.
- the selectively attachable material extending into the rubber base is permanently attached therein by the process of vulcanization when the base is cured. During the curing process, heat softens the rubber base while pressure forces the selectively attachable material extending toward the rubber base into the same. Accordingly, the rubber base is cross linked with the material as the sheet is cured to form a permanent bond.
- the resulting mat of the present invention can withstand repeated laundering without the fastener becoming separated from the rubber base.
- Fig. 1 is a perspective view of a mat used in an entry way of a commercial building in accordance with the preferred embodiment of the present invention.
- Fig. 2 is a perspective view of the mat of Fig. 1, showing a carpet, a rubber base, and a fastener in accordance with the preferred embodiment of the present invention.
- Fig. 3 is an enlarged perspective view of a corner of the mat of Fig. 1, showing the construction of the fastener and of a mating fastener in accordance with the preferred embodiment of the present invention.
- Fig. 4 is a side view of a press for making the mat of Fig. 1 in accordance with the preferred embodiment of the present invention.
- Fig. 1 shows a selectively attachable floor covering capable of withstanding frequent laundering in accordance with the preferred embodiment of the present invention.
- the floor covering is a mat 12 used at an entrance way 14 of a commercial building 16 to collect dirt and water tracked therein. Accordingly, the mat 12 prevents soiling and damage to a carpet or other permanent floor covering that cannot be easily cleaned or replaced.
- the mat 12 is selectively attached to a floor 18 of the commercial building 16 with fasteners capable of withstanding frequent laundering. Thus, the mat 12 is held firmly in place during use to reduce the likelihood of slip and fall accidents, but can be easily and frequently removed for laundering when soiled.
- the mat 12 comprises a flat carpet 20 with an integral rubber base 25 and a plurality of integral fasteners 30 protruding from a bottom 26 of the rubber base 25.
- the carpet 20 includes a base fabric 22 and pile yarns 24 formed by tufting fibers to the base fabric 22 and trimming the top ends of the pile yarns 24.
- the process for making the carpet 20 is well known in the art and thus will not be further described herein.
- the pile yarns 24 are yarns composed of cotton fibers, polyvinyl alcohol fibers, nylon fibers, or the like. In the preferred embodiment, the pile yarns 24 are composed of nylon fibers because of the durability, appearance, and resistance to linting of the same.
- the rubber base 25 is cured directly to the base fabric 22 of the carpet 20. During the curing process, which is described below in detail, the rubber of the base 25 is vulcanized to cross link with the base fabric 22 and form a permanent bond. Accordingly, the mat 12 can withstand repeated laundering without the carpet 20 becoming separated from the rubber base 25.
- the rubber base 25 is made of nitrile-butadiene rubber (NBR) because of its resistance to oils and ability to withstanding frequent laundering.
- NBR nitrile-butadiene rubber
- a fastener 30 is disposed at each corner of the rubber base 25 to provide gripping support for the mat 12 in all directions.
- a fastener 30 may also be disposed in the center of the rubber base 25 for further gripping support. Moreover, a fastener 30 may be located along each edge of the rubber base 25 or along a leading edge and a trailing edge of the rubber base.
- each fastener 30 comprises two opposing sections of selectively attachable hook or loop material, such as that manufactured and sold by Aplix, Inc. of Charlotte, North Carolina.
- the selectively attachable material is loop material because it forms a better bond with the rubber base 25 and because it is less abrasive to the carpet 20 during laundering.
- hook material may be used for one or both sections.
- a first section of loop material 32 extends upwardly into the bottom 26 of the rubber base 25 and includes a first backing 33 abutting the bottom of the rubber base.
- a second, opposite facing section of loop material 34 protrudes downwardly from the first section 32 and includes a second backing 35 permanently bonded to the first backing 33.
- the second backing 35 is permanently bonded to the first backing 33 by stitching.
- the backings may also be permanently bonded by ultrasonic welding or by water- resistant adhesives.
- the mat 12 of the present invention is made by first separately forming the carpet 20 and the fasteners
- the fasteners are formed by sewing the backings of the loop material together.
- the carpet 20 is placed in a curing press 50 above an uncured sheet of rubber 52 that will cure in the press to form the rubber base 25.
- the curing press 50 is of a type that is well known in the art and, generally described, comprises a top platen 54 with heating coils 56 and a bottom bladder 58.
- the fasteners 30 are disposed under, and at the corners of the rubber sheet 52.
- the rubber sheet 52 is sandwiched between the carpet 20 and the fasteners 30 such that the sheet will vulcanize and cross link with both the carpet and the fasteners.
- the rubber sheet 52 is vulcanized by the process of heating the press 50 with the heating coils 56 to between 250 and 300 degrees Fahrenheit and inflating the bladder 58 to provide between 50 and 60 pounds pressure (psi) in the press.
- the curing process takes between 15 and 25 minutes.
- the heat softens the rubber sheet 52 while the pressure forces the first section of loop material 32 of each fastener 30 into the bottom 26 of the sheet.
- the rubber sheet 52 is cross linked with the loop material as the sheet is cured to form a permanent bond.
- the phase permanent bond means a bond that will not become loosened or undone by normal use and extended commercial laundering. As a result, the mat 12 can withstand repeated laundering without the fasteners 30 becoming separated from the rubber base 25.
- the mat 12 is removed from the curing press 50 and is ready for extended use and laundering.
- the fasteners 30 of the mat 12 are selectively attached to the floor 18 of the commercial building 16.
- the fasteners 30 are attached with mating fasteners 60 anchored to the floor.
- the mating fasteners 60 may be anchored by adhesive tape and other well known means.
- the fasteners 30 comprise loop material
- the mating fasteners 60 comprise hook material
- the mating fasteners 60 comprise a mating material.
- the fasteners 30 and the mating fasteners 60 form a fastening system 62 that allows the mat 12 to be selectively attached to the floor 18 for use and easily removed for laundering when the mat has become soiled. Further, because the fasteners 30 are permanently attached to the rubber base 25, they can withstand repeated laundering such that the mat 12 can be reused for an extended period.
