Abstract
Description
- This application claims priority to U.S. patent application Ser. No. 09/124,095 filed Jul. 29, 1998, entitled, “Padded Raised Flooring Panels and Coverings,” and U.S. patent application Ser. No. 60/123,883 filed Mar. 11, 1999, entitled, “Raised Floor Tape Locator System for Carpet Tile,” both which are incorporated by reference herein.
- This invention relates to raised panel or access flooring systems and floor coverings, including carpet and carpet tile and resilient sheet and tile products.
- Myriad materials have been used for flooring and floor coverings in buildings, including virtually every natural and human-made material imaginable, such as wood, stone, concrete, cork, plastics, paint, carpets, rugs, vinyl sheets and tiles, sawdust, rushes, and animal skins, to name just a few. Rugs and carpets in a wide variety of materials, patterns and constructions have been manufactured for centuries, particularly for use in homes. As recently as the middle of the twentieth century, carpets and rugs were virtually never used in commercial and industrial buildings like manufacturing facilities, stores and offices. Floors in such locations utilized “hard surface” materials like concrete, concrete compositions, wood or sheet materials like linoleum. Beginning in approximately the late 1960's and 1970's, carpet and carpet tiles began to be used extensively in commercial and “light” industrial buildings, a trend that was accelerated by the advent of new carpet technologies that provided more durable and attractive products and by the popularity of “open” floor plan offices.
- As a result of these developments, the comfort and aesthetic appeal of carpet and carpet tile have come to be widely expected in offices and other commercial environments.
- Floor structures in most office and commercial buildings are concrete. Typically, a modest amount of cabling in conduits and the like are buried in the concrete. Drop ceilings are frequently used in office and other commercial buildings to conceal the many other infrastructure elements normally found in buildings, such as electricity and communications cabling; water and sewage pipes; and heating, ventilation and air conditioning (HVAC) ducts. However, difficulty in accessing these elements and the cabling needs of some computer installations have led to the increased use of raised panel flooring. Raised panel flooring, also known as access flooring, typically includes multiple rigid floor panels which are supported by a pedestal and stringer structure that rests on the concrete slab floor of the building. An example is shown in U.S. Design Pat. No. D370,060, entitled “Modular Grid Understructure,” dated May 21, 1996, which is incorporated herein by this reference. The panels provide a stable floor, while the support structure creates a space or “subfloor” under the panels and above the concrete slab floor for routing infrastructure elements.
- Rigid flooring panels are typically constructed of aluminum, steel, wood, concrete or various combinations thereof. For example, flooring panels may be made of concrete or wood encased in a steel shell. These unyielding surfaces are uncomfortable and noisy to walk on. Also, bare metal surfaces (or even painted or coated surfaces) may be unattractive, creating an unpleasant environment, particularly in light of the expectations mentioned above that have developed as a result of widespread use of carpet in office and commercial environments. Thus, access floors often are covered with a sound and shock absorbent material, such as carpet tile. The use of carpet tiles also improves the aesthetic appearance of the floor.
- Carpet tiles can have a wide variety of constructions. However, carpet tiles typically include at least two layers: a top or “face” layer and a bottom or “backing” layer. The face layer is a relatively thin textile fiber layer, typically tufted, fusion bonded, woven or needle punched. The backing layer is a relatively thick resilient pad that contributes many desirable properties to the overall tile, such as cushioning and sound attenuation. The backing layer is hidden from view under the face layer.
- Accessing the subfloor requires removal and reinstallation of the rigid panels and any carpet tiles or other floor covering lying on the panels. Frequent movement of the tiles, traffic on the floor and other contacts with the tiles often damage the tiles, requiring replacement. The damage to the tiles is typically restricted to the face layer of the tile; the backing layer is rarely damaged. Moreover, purely cosmetic damage to the backing layer can be ignored since the backing is not visible. In contrast, even minor damage to the facing layer may necessitate replacement of the entire tile. Thus, as a result of minor damage to only one portion of the tile, the entire tile must be discarded. The disposal and/or recycling of both the face and backing layers is particularly difficult, because, due to the dissimilarities in materials, the various carpet components must be separated prior to recycling. As a result, damaged carpet tiles are often discarded, creating disposal costs and environmental problems. Alternatively, recyclers are forced to used complex and expensive recycling systems that can separate the dissimilar materials. It would be desirable to provide systems for use with access flooring which minimizes the disposal, recycling and/or replacement cost of damaged tiles while providing the aesthetic and functional characteristics of carpet tile or other conventional floor treatments.
- One approach in the art was a steel panel with welded side flanges and a tile having a carpet square bonded thereto and a base plate having flanges with an inward projection that snaps onto the steel panel as disclosed by U.S. Pat. No. 4,996,818 issued to Bettinger, Mar. 5, 1991. In Bettinger, the entire tile including the bonded carpet and the base plate are removed. Bettinger does not provide for detaching only the carpet portion of the tile. Attempts to remove the bonded carpet from the tile are likely to destroy the carpet leaving it unusable. Thus, with Bettinger, the entire tile must be removed and not just the bonded carpet. Thus, a need still exists for a system and method that provides for detaching the upper carpet portion of a floor covering of a raised access floor panel system where the carpet is not destroyed and may be reused.
- This invention addresses these limitation by presenting a relatively thick, resilient pad is bonded directly to and covers the entire surface of an access floor panel. The pad provides the functional characteristics of conventional floor treatments by absorbing impacts, attenuating sound and contributing to the desired “feel” when standing or walking on the floor. “Installation” of the pad occurs in the factory where it is bonded to the panel, rather than on-site, thereby simplifying on-site activities.
- Modules of “reinforced face cloth” having only a face layer and a stabilizing layer are used to cover the pad. The reinforced face cloth modules provide the desired aesthetic effect of conventional floor treatments. The reinforced face cloth modules also extend the life of the pad by reducing wear.
- In one embodiment, the reinforced face cloth modules are not bonded to the padded floor panels. Alternatively, the modules may be bonded lightly to the pad with a pressure sensitive adhesive that allows easy removal. The pressure sensitive adhesive prevents the module from sliding without limiting the ability to remove the module from the pad. In either case, damaged or worn modules can be replaced with a minimum of material usage and dramatically lower cost than if conventional floor treatments were replaced. Furthermore, because the pad and the modules are at most only lightly bonded together, the complexity and cost of separating the modules from the pad and recycling either or both the pad and the module is reduced.
- In an alternative embodiment of this invention, the reinforced face cloth modules affix to the pad utilizing hook and loop fasteners.
- The pad may be cast directly onto the panel or may be manufactured separately and bonded to the panel with an adhesive. In the event the pads are cast directly onto the panel, additional pads may be manufactured separately for use to replace damaged pads. Alternatively, damaged pads may be repaired by filling in the damaged area with an appropriate repair material, or panels having damaged pads may simply be replaced.
- The reinforced face cloth modules may be manufactured in sizes corresponding to the panels or may be manufactured in any desired standard sizes and distributed on the floor independent of the panel interfaces.
- Accordingly, it is an object of the present invention to provide aesthetic and wear coverings for raised flooring panels which are easily replaced with a minimum of waste.
- Another object of the present invention is to provide shock absorbent and sound attenuating coverings for raised flooring panels in which the coverings are affixed to the panel.
- Another object of the present invention is to provide coverings for raised flooring panels having an inexpensively replaced face cloth module.
- Another object of the present invention is to provide coverings for raised floor panels which minimize waste and reduce recycling costs.
- Other objects, features and advantages of the present invention will become apparent with reference to the drawings, the following description of the drawings and the claims.
- FIG. 1 is a perspective view of a room with a partially installed raised floor with corners of components of the panel covering partially lifted to show the structure of the covering.
- FIG. 2 is an elevation view of a raised flooring panel and covering taken along line2-2 in FIG. 1.
- FIG. 3 is a side elevation view of a hook and loop fastener interposed between a reinforced face cloth module and a pad.
- FIG. 4 shows a side elevation view of a raised flooring panel having a recess adapted to receive a hook and loop fastener.
- FIG. 5 shows a side elevation view of a raised flooring panel having a recess without utilizing a hook and loop fastener.
- FIG. 1 illustrates the installation of a raised
floor system 10 usingcovering 12 in accordance with the present invention. Raisedfloor 10 includessupport columns 14 andfloor panels 16.Columns 14 are typically distributed on the floor of a room at intervals that coincide with theintersection 18 of the corners ofadjacent panels 16. - Referring to FIG. 2, each
panel 16 is covered with apad 20. The paddedpanels 16 are covered with reinforcedface cloth modules 22.Pad 20 may be made of any durable, resilient material. Suitable materials include solid, flexible polyvinyl chloride (PVC); foamed PVC; solid or foamed polyurethane, solid or foamed modified bitumen products such as urethane modified bitumen; or any other materials which provide the desired characteristics. If PVC products are used, they may be made from recycled materials. In particular, urethane modified bitumen, such as that disclosed in U.S. Pat. No. 5,096,764, entitled “Printable Carpet Tile and Method,” the entirety of which is incorporated herein by this reference, may be used to producesuitable pads 20. - The appropriate thickness and other properties of
pad 20 should be determined by reference to the anticipated environment. For instance, pad 20 may be made thicker to create additional shock absorption or thinner where minimized weight is important.Pad 20 may be cast directly ontopanel 16 using known manufacturing methods.Pad 20 also may be cast or otherwise formed separately and bonded topanel 16 using any suitable adhesive. In either case,additional pads 20 may be manufactured separately for use as replacement pads. -
Pads 20 cover the entire upper surface ofpanel 16. Thus, whenpanels 16 are installed as shown in FIG. 1, a continuous, gap free surface is formed.Panels 16 are not visible underpads 20. As shown in FIG. 2,panels 16 may have tabs, flanges or other interlocking means 30 for joining each panel to an adjacent panel. The top surfaces of joiningmeans 30 need not be covered bypads 20 as they will be concealed under the edge of the adjoining panel 16 (and that panel's corresponding pad 20). - Reinforced
face cloth modules 22 are made of atopcloth layer 24 and a stabilizinglayer 26.Topcloth layer 24 may be any desirable surface, such as a woven, tufted, fusion bonded, needle punched or any other suitable textile layer or, alternatively, linoleum, vinyl or any other form of sheet or tile or other suitable floor treatment product. - Stabilizing
layer 26 may be made of non-woven fiberglass or other suitable materials in the minimum amount necessary to provide the desired dimensional stability. Stabilizinglayer 26 is dimensionally stable and thereby serves to stabilize reinforcedface cloth module 22 so that it lies flat, i.e., it preventsmodule 22 from curling up at the edges or assuming a dome-like shape. Stabilizinglayer 26 is not a polymeric layer alone. The stabilizinglayer 26 is a layer that stiffens and substantially reinforces polymer materials and cannot be an amorphous polymer. Typically the stabilizinglayer 26 is fiberglass and could be other polymer fibers but cannot be amorphous polymers that tend to stretch, grow, and dome.Layers layer 26 may be made up of a sheet of non-woven fiberglass encased in an adhesive or plastic, such as the urethane modified bitumen material described above.Layer 26 may be pressed againstlayer 24 before the adhesive or plastic material cures, thereby bonding the layers together. Using urethane modified bitumen encapsulation as an adhesive reduces the amount of material required to assemble a complete module and simplifies the manufacturing process. - Reinforced
face cloth modules 22 may be made to fitpanels 16 exactly or may be made in sizes that differ from the panel dimensions. In either case, as shown in FIG. 1, reinforcedface cloth modules 22 are placed on the floor formed bypads 20 in such a manner as to completely coverpads 20. If reinforcedface cloth modules 22 are the same size aspads 20, they may be (but need not necessarily be) placed so that the interfaces between adjacent reinforcedface cloth modules 22 coincide with the interfaces betweenadjacent pads 20. Alternatively, or if reinforcedface cloth modules 22 do not match the size ofpads 20, reinforcedface cloth modules 22 may be positioned without regard to the interfaces betweenadjacent pads 20. - If
face cloth modules 22 are sufficiently stable, they may be positioned without any means for bonding them to pad 20. Alternatively, pressure sensitive or other adhesives or other means can be utilized to securemodule 22 in place atoppads 20. Suitable adhesives include, but are not limited to acrylic-based pressure sensitive adhesives. - Although the foregoing is provided for purposes of illustrating, explaining and describing certain embodiments of the floor covering the present invention in particular detail, modifications and adaptations to the described floor covering and other embodiments will be apparent to those skilled in the art and may be made without departing from the scope or spirit of the invention as described in the following claims.
- For instance, FIG. 3 shows an additional means for affixing reinforced
face cloth modules 22 topads 20. FIG. 3 shows an alternative embodiment for affixing the reinforcedface cloth modules 22 topads 20. Hook andloop fasteners 40 attach the reinforceface cloth modules 22 to thepads 20. Hook andloop fasteners 40 serve to accurately hold a floor covering 22 in place on thepanels 16 while themodules 10 are removed to another location. - In another alternative embodiment shown in FIG. 4, hook and
loop fasteners 40 position in arecess 42 of thepanel surface 16. Hook andloop fasteners 40 recessed in thepads 20 eliminate even minute deflections in the upper surface of the reinforcedface cloth modules 22. Therecess 42 can be about half the thickness of the hook andloop fastener 40 or therecess 42 can equal the thickness of the hook andloop fastener 40. - In yet another alternative embodiment shown in FIG. 5, the
recess 42 can be utilized without the hook andloop fastener 40. Many recess configurations are possible ranging from a single hook andloop fastener 40 system to one with many hook andloop fasteners 40 configured in a variety of groupings. For instance, a corner recess system in which any combination of locators can be used. Alternatively, a perimeter arrangement recess system can serve to locate and hold reinforcedface cloth modules 22 in place.
