Definitions
- the present invention relates to a floor mat More specifically, the present invention relates to a floor mat comprising a dust-adsorbing sheet, and a mat base for supporting and fastening the dust-adsorbing sheet Owing to the property of the material that is used, the dust adsorbing sheet used in the present invention exhibits the action for adsorbing oils, solvents and other liquids in addition to the action for adsorbing dust and dirt on the floor surface or from the bottoms of shoes. Therefore, the floor mat of the present invention can be extensively used being placed around a variety of machines in the factories, in gas stations and in the backyards of restaurants to guarantee clean and safe environment The present invention is also concerned with a mat base for use in the floor mat
- Japanese Unexamined Utility Model Publication (Kokai) No 4-10848 discloses a mat in which the mat body (corresponding to a dust-adsorbing sheet) is constituted by a nonwoven fabric of a resin material such as polypropylene, and a number of spot-like slip- preventing protuberances are formed on both the front and back surfaces of the mat body.
- Fig 1 illustrates an example of the mat
- a mat body 21 made of a nonwoven fabric of, for example, polypropylene is subjected, on the back surface thereof, to the emboss working, and is further provided, on both the front and back surfaces thereof, with a number of spot-like slip preventing protuberances 22
- the slip-preventing protuberances 22 are formed by foaming a latex containing rubber
- the mat body 21 is used on a base plate 23, and is fitted into a recessed portion 25 surrounded by a rising portion 24 of the base plate 23
- the mat that is shown is placed in a gas station, in a factory or in a restaurant to remove oil and the like adhered to the bottoms of shoes When the workers or passersby walk on this mat, however, the ends of the mat body are easily turned up, which may give rise to the occurrence of accident such as stumbling Besides, the constitution of the mat body is complex, and the step of production is complex, too, driving up the cost of production.
- a mat that is commercially available may be the one having constitution as shown in Fig. 2.
- This mat has a feature in that a number of cylindrical protuberances 32 are formed on the surface of a rubber tray 33, and a thick sheet 31 made of a nonwoven fabric is placed on a portion surrounded by the peripheral edge 34 of the tray 33.
- the protuberances 32 on the surface of the tray 33 prevents the sheet 31 from undesirably moving.
- the nonwoven fabric constituting the sheet 31 exhibits the action for removing the dust and oily dirt.
- the sheet 31 can be replaced after it is fouled to a noticeable degree.
- this mat is not capable of solving the above-mentioned important problem of turn-up at the edges of the sheet caused as it is trod, like the above- mentioned mat.
- a mat base for a floor mat for supporting and fastening a dust-adsorbing sheet wherein said mat base is made of a rubber-type material, has a surface having been subjected to a sheet stabilizing treatment to prevent the movement, caused by the slipping, of the dust- adsorbing sheet, and has along its peripheral edge a sheet fastening fitting formed integrally with the mat base.
- a floor mat comprising a dust-adsorbing sheet, and a mat base for supporting and fastening the dust-adsorbing sheet
- said dust-adsorbing sheet is made of a nonwoven fabric material that can be replaced
- said mat base is made of a rubber-type material, has a surface having been subjected to a sheet stabilizing treatment to prevent the movement, cased by the slipping, of the dust-adsorbing sheet, and has along its peripheral edge a sheet-fastening fitting formed integrally with the mat base.
- Figure 1 is a perspective view illustrating a conventional floor mat
- Figure 2 is a perspective view and a sectional view illustrating a portion of another conventional floor mat
- Figure 3 is a perspective view illustrating a preferred example of a floor mat of the present invention.
- Figure 4 is a sectional view illustrating a portion of the floor mat shown in
- the present invention is to solve the above-mentioned problems inherent in known floor mats.
- a floor mat which uses a mechanical fastener (so-called "surface fastener”).
- a mechanical fastener is mounted at least partly on the peripheral edge of a rubber mat base, so that a dust-adsorbing sheet of a nonwoven fabric can be easily fastened.
- Use of this floor mat makes it easy to replace the dust-adsorbing sheet, prevents turning-up at the edges of the sheet, and does not cause the structure of the mat or the production thereof from becoming so complex.
- the mechanical fastener is continuously used for extended periods of time, however, fiber dust from the dust-adsorbing sheet adhere onto the hooks. In order to avoid a drop in the sheet-fixing effect, therefore, it is necessary to remove the fiber dust once in a while. That is, to provide the floor mat that requires easy maintenance is one of the problems to be solved by the present invention.
- the object of the present invention is to provide an improved floor mat which is simple in the structure, cheaply produced maintaining a good yield, does not permit the ends of the sheet to be undesirably turned up while it is being used, and requires easy maintenance.
- the floor mat according to the present invention is, usually, constituted by a combination of two elements, i e , by a combination of a dust-adsorbing sheet, and a mat base for supporting and fastening the dust-adsorbing sheet.
- the dust-adsorbing sheet is made of a nonwoven fabric material which can be replaced or, in other words, which can be discarded after the use.
- the nonwoven fabric that can be discarded is usually produced as a recyclable product, which is very useful from the standpoint of maintaining environment and saving resources
- the nonwoven fabric material can be produced from natural or synthetic fiber materials using conventional manners Suitable examples of the fiber material include rayon, polyamide (nylon), polyester, polypropylene and the like, though the fiber material is in no way limited thereto only
- suitable fiber materials and production methods may be arbitrarily selected and combined together by taking desired effects and other factors into consideration
- a polypropylene fiber having excellent oil- adsorbing property is used as a starting material, and is finished into a sheet of any desired shape for adsorbing dust and dirt by the spun bond method, melt blow method or needle punch method
- the nonwoven fabric material may be a composite material
- the dust-adsorbing sheet can be used in various shapes and sizes depending upon the place where the floor mat is used or depending upon the desired effect for adsorbing dust and dirt Usually, the dust-adsorbing sheet is of a rectangular shape measuring, generally, 30 to 100 cm in width, 30 to 500 cm in length and 2 to 10 mm in thickness and, more preferably, measuring 45-70 cm in width, 45 to 140 cm in length and 3 to 8 mm in thickness When it is desired to obtain the effect for adsorbing dust and dirt over a wide area in a special application, the dust-adsorbing sheet may be used in a size larger than the above-mentioned range
- the mat base is desirably made of a rubber-type material to support and fasten the dust-adsorbing sheet
- a rubber-type material include, though not necessarily limited thereto only, synthetic rubbers such as nitrile rubber, styrene-butadiene rubber, isoprene rubber, butadiene rubber, EPDM (ethylene-propylene-diene terpolymer) rubber, and the like
- the rubber-type material used in the embodiment of the present invention has a hardness of, desirably, from 50 to 80 in terms of Shore A hardness as measured by using a durometer When the hardness is smaller than 50, the strength so drops that the mat base no longer withstands the use for extended periods of time When the hardness exceeds 80, on the other hand, it becomes difficult to completely prevent the dust-adsorbing sheet from slipping despite the presence of protuberances for preventing the slipping
- the cylindrical protuberances each measuring 1 mm high and 2 mm in diameter can be arranged maintaining a distance of 1 mm so as to constitute an equilateral triangle Moreover, the protuberances can be formed simultaneously at the time of forming the mat base from the rubber-type material
- the sheet stabilizing treatment may be to coarsen the surface of the mat base in addition to forming the groups of protuberances as described above
- the treatment for coarsening the surface can be effected relying on a customary method (e.g., a method which uses a rugged mold for molding the mat base, a method of producing a mat base after having laminated a film with rugged surface on the surface of the mold). It is further allowable to employ a method of grinding the surface of the mat base to form ruggedness on the surface, a method with utilizes the corroding action using chemicals, or any other method.
- the degree of coarseness is sufficient when ruggedness is formed on the surface of the mat base to a degree that can be perceived and a desired slip-preventing effect is obtained.
- the peripheral edge of the mat base is provided with a sheet-fastening fitting that is integrally formed with the mat base.
- the sheet-fastening fitting can be constituted as a member of the peripheral edge of the mat base.
- the sheet -fastening fitting can be advantageously formed by folding the peripheral edge of the mat base or joining a member (which may be made of the same rubber-type material as the mat base or of any other material when it is intended to obtain good appearance or ornamental effect) having the same shape as the folding portion to the peripheral edge of the mat base integrally therewith by sticking, adhesion with pressure or any other method.
- the sheet-fastening fitting being constituted as described above, a pocket-like space is formed enabling the peripheral edge of the dust-adsorbing sheet to be inserted and held therein.
- the sheet-fastening fitting preferably has at least one notch formed in the peripheral edge of the mat base.
- the peripheral edge is turned up to facilitate the insertion.
- it is recommended to form nearly linear notches or V-shaped or U-shaped notches at four corners when the mat base is of a rectangular shape.
- FIG 3 is a perspective view illustrating a preferred floor mat of the present invention which is disassembled into a mat base and a dust-adsorbing sheet.
- the mat base 1 of the present invention is made of an acrylonitrile rubber having high resistance against oils, and measures 955 mm wide, 1541 mm long and 6 mm thick.
- the mat base 1 has a Shore A hardness of about 60.
- Cylindrical protuberances 2 are formed in groups on the whole surface of the mat base 1 to prevent the dust-adsorbing sheet from moving due to slipping and to stably fasten the sheet.
- the protuberances 2 are formed simultaneously with the formation of the mat base 1 each measuring 1 mm in height and 2 mm in diameter. Though the protuberances 2 are formed on the whole surface of the mat base 1 in the diagramed embodiment, the protuberances 2 may be locally formed provided the effect of the present invention is not adversely affected.
- a pocket-like space 3 (see Fig. 4) by folding the peripheral edge 1 1 so that the peripheral edge of the dust-adsorbing sheet 5 can be inserted and held therein thereby to fasten the sheet.
- the peripheral edge 11 of the mat base 1 is folded to form the pocket-like space 3.
- a separate member (which may be of the material same as, or different from the mat base 1) corresponding to the peripheral edge 1 1 may be joined with an adhesive to the end of the mat base 1 to integrally bond them together.
- V-shaped notches 4 are formed in the peripheral edge 1 1 of the mat base 1 so that, when the peripheral edge of the dust-adsorbing sheet 5 is to be inserted in the pocket-like space 3, the peripheral edge thereof can be turned up to facilitate the operation of insertion.
- N-shaped notches 4 are formed at four corners of the rectangular mat base 1.
- the shape of the notch 4 is not limited to the V-shape as shown but may be of a linear shape or a U-shape by taking the working efficiency into consideration.
- the places for forming the notches 4 are not limited to four corners of the rectangular mat base 1 but may be arbitrarily changed depending upon the desired effect.
- the dust-adsorbing sheet 5 comprises a nonwoven fabric obtained by treating a polypropylene fiber by the needle punch method, and measures 924 mm wide, 1520 mm long and 2.5 mm thick (corresponds to the amount of weight of 270 g/m 2 ).
- the dust-adsorbing sheet 5 comprising the polypropylene nonwoven fabric can be incinerated leaving small amounts of ash and making it possible to decrease the cost of waste disposal.
- the floor mat of this embodiment comprises the above-mentioned mat base
- the dust-adsorbing sheet 5 enables the dust- adsorbing sheet 5 to be stably fastened to the central portion (surrounded by the peripheral edge 1 1) of the mat base 1.
- the notches 4 formed at four corners of the mat base 1 make it very easy to insert the dust-adsorbing sheet 5 in the pocket-like space 3.
- the protuberances 2 formed on the surface of the mat base 1 prevent the dust-adsorbing sheet 5 from undesirably slipping.
- the peripheral edge of the dust-adsorbing sheet 5 is held in the pocket-like space 3, accidents caused by the turned-up ends of the dust-adsorbing sheet 5 is prevented in advance.
- the dust-adsorbing sheet 5 that is contaminated and must be replaced can be easily replaced by a new one.
- the following evaluation test was conducted in order to make sure excellent slip-preventing effect exhibited by the mat base of the present invention having protuberances on the surface thereof compared with the mat base having smooth surface.
- Sample mat base 1 (article of the present invention):
- a mat base (Shore A hardness of about 60) made of an acrylonitrile rubber similar to the mat base of the embodiment shown in Fig. 3 was prepared. During the testing, however, the peripheral edge that hinders the testing was removed in advance. The size was 60 mm wide, 60 mm long and 6 mm thick. The cylindrical protuberances measured 1 mm in height and 2 mm in diameter.
- Sample mat base 2 (article for comparison):
- a sample mat base 2 was the same as the sample mat base 1 except that cylindrical protuberances were all removed from the surface to make the surface smooth.
- the size was 150 mm wide, 3000 mm long and 2.5 mm thick (corresponds to the amount of weight of 270 g/m 2 ).
- the dust-adsorbing sheet was placed on the central portion of the sample mat base 1, a spring balance was attached to one side of the dust-adsorbing sheet, and the dust-adsorbing sheet was pulled in a horizontal direction to move it.
- the initial moving resistance of the dust-adsorbing sheet was measured to be 500 g.
- the sample mat base 2 was used instead of the sample mat base 1 to similarly measure the initial moving resistance.
- the dust- adsorbing sheet moved without any resistance, and the initial moving resistance was measured to be 0 g.
- the floor mat of the present invention includes the dust-adsorbing sheet which, owing to its material, exhibits the action for adsorbing dust and dirt on the floor or on the bottoms of shoes, as well as the action for adsorbing oils, solvents, and other liquids. Therefore, the floor mat of the present invention can be extensively used being placed around the machines in the factories, in the gas stations, in the backyards of restaurants and in the like places to guarantee a clean and safe environment. While in use, furthermore, the dust- adsorbing sheet is prevented from slipping or from being turned up at the ends, and prevents the workers and passersby from running into an accident caused by stumbling.
- the notches and pocket-like space formed in the peripheral edge of the mat base of the invention enable the contaminated dust-adsorbing sheet to be replaced by a new dust-adsorbing sheet easily and reliably.
- the mat base of the present invention does not catch fiber dust or dirt of the dust adsorbing sheet, and avoids a problem of drop in the sheet-fastening ability when a mechanical fastener is used and further eliminates the additional maintenance work for removing the fiber dust and dirt.
- the mat base is light in weight, tough and is flexible, and, hence, the floor mat can be used in any place.
