The invention relates to a method for installing a surface covering and apparatus for facilitating the method.
Surface coverings such as tile, laminates, vinyl, ceramics, wood, carpet and other textiles, may be installed by attaching the coverings to the surface being covered. Installation is primarily concerned with attachment of the element to the surface. Gaps between elements may occur, facilitating entry of unwanted matter such as dust or liquids. Larger gaps may be unsightly.
In accordance with a broad aspect of the present invention there is provided a method for installing a first surface covering element and a second surface covering element onto a surface, each of the elements having one half of a hook and loop attachment system, and the surface having the other of the hook and loop attachment system, the method comprising:
(i) placing the first element onto the surface so that at least some of the respective hooks and loops of the first element and surface engage;
(ii) placing the second element to marginally overlap the first element by a generally uniform amount, so that at least some of the respective hooks and loops of the second element and surface engage; and
(iii) applying a force to the second element, adjacent the overlap, to encourage the second element to move and to become generally coplanar with the first element and to eliminate the overlap.
The method may further comprise in step (ii), placing the second element with an amount of overlap that causes the loops to bias the second element against the first element after step (iii).
In another aspect, the amount of overlap is selected to cause the second element to be biased against the first element to create a seal between the first and second elements that is resistant to liquid transfer.
In another aspect, the amount of overlap in step (ii) is determined by a measurement of the maximum extension of the possible movement between the second element and the surface when at least some of the respective hooks and loops of the second element and surface engage, and the overlap is less than or equal to such maximum extension.
In another aspect, the amount of overlap in step (ii) is a function of the maximum resiliency of the loops.
In another aspect, the amount of overlap in step (ii) is a function of the maximum length of the loops.
In another aspect, the surface is a subfloor, and the method further comprises, before step (i), the step of placing the subfloor onto a floor, without attaching the subfloor to the floor.
In another aspect, the force is applied by hand.
In another aspect, the force is applied by a blunt instrument.
In another aspect, the force is applied progressively from one area of overlap to another area of overlap.
In another aspect, in step (ii) the second element is placed in a staggered relationship relative to the first element.
In another aspect, the method further comprising the step of:
(iv) placing a third element to marginally overlap both the first and second elements along adjacent edges by generally uniform amounts, so that at least some of the respective hooks and loops of the third element and surface engage; and
(v) applying a force to the third element, adjacent the overlap, to encourage the third element to move and to become coplanar with the first and second elements and to eliminate the overlaps.
In another aspect, the method further comprising the step of:
(iv) repeating all previous steps for a third element in conjunction with at least one of the first and second elements.
In another aspect, the first element is rigid.
In another aspect, the first element is made of one of vinyl, wood, linoleum, plastic, ceramic and rigid backed carpet.
In another aspect, the method further comprising, after step (i), positioning a template relative to the first element to cause the second element to overlap the first element by a predetermined amount; and, after step (ii), removing the template.
In another aspect, the first element also moves to tension the loops.
In another embodiment there is provided a decorative floor covering installation comprising:
a first surface covering element;
a second floor covering element;
a surface for receiving the first and second elements, each of the elements having one half of a hook and loop attachment system, and the surface having the other of the hook and loop attachment system, the first and second elements being attached to the surface by the hooks and loops, and the first and second elements being biased against one another.
In another aspect, at least some loops are approaching maximum extension and movement of at least one of the elements away from the other is limited.
In another aspect, at least some loops are approaching maximum extension so that the first element is biased against the second element to form a liquid resistant seal.
In another aspect, the surface is a free floating subfloor.
In another aspect, wherein the first element is rigid.
In another aspect, wherein at least some loops are extended by a predetermined amount.
In another aspect, the predetermined amount is at least twenty-five percent of a maximum extension of the loops.
In another aspect, the first element is flexible and resists folding.
In another aspect, the first element is made of one of vinyl, wood, linoleum, plastic, ceramic and rigid backed carpet
In a further embodiment there is provided a method for making a floor covering module having a covering element with at least one side substantially covered in one of hooks and loops of a hook and loop attachment system, and a sheet substantially covered the other of hooks and loops, the method comprising the steps of:
(i) bending the sheet;
(ii) placing the covering element onto the sheet to permit at least some of the hooks to engage at least some of the loops; and
(iii) flattening the combined sheet and covering element for placement onto a surface.
In another aspect, the sheet is bent to present a convex surface for attachment to the covering element.
In another aspect, the sheet is bent to present a generally helical surface for attachment of the covering element.
In another aspect, the covering element is placed onto the sheet to overlap along at least one edge.
In a further alternative embodiment there is provided a planar surface comprising a subfloor substantially covered with loops and at least two decorative covering elements having complementary loops for attachment to hooks, in which at least some of the loops of at least one of the decorative covering elements are in tension pulling that element in to abutment with the other element.
In a yet further embodiment there is provided a method for installing a first surface covering element onto a surface, wherein the element has one half of a hook and loop attachment system, and the surface has the other of the hook and loop attachment system, the method comprising the steps of: (i) placing the first element onto the surface so that at least some of the respective hooks and loops of the first element and surface engage; (ii) applying a force to the first element in a direction generally parallel to the surface, to encourage tensioning in the loops; and (iii) securing the first element into place.
Other and further advantages and features of the invention will be apparent to those skilled in the art from the following detailed description of embodiments thereof, taken in conjunction with the accompanying drawings.
The present invention will be further understood from the following detailed description of embodiments of the invention, with reference to the drawings in which:
a illustrates a loop in various degrees of extension;
b is a top view of
a illustrates the installation of decorative elements having a complimentary tongue and groove;
Similar references are used in different figures to denote similar components. Proportions and positioning of illustrated elements may be exaggerated or distorted in order to better illustrate the methods and apparatus.
Releasable attachment systems have been used to conveniently install decorative floor coverings. In particular, complimentary hook and loop attachment systems, such as those disclosed and in prior patents (and applications) including U.S. Pat. Nos. 6,306,477; 6,298,624; 6,802,167; 7,096,632; and application Ser. Nos. 10/013,688; 10/543,905; 10/543,904; 10/543,902; 10/543,906; 10/879,149; 10/543,901; and 10/543,903, all of which are herein incorporated by reference.
In general, a field of hooks (or loops) may be provided on a surface to be covered. A decorative covering may be provided having a side covered with loops (or hooks, as the case may be) for engaging the complimentary hooks (or loops) of the surface. This arrangement has the advantage that the decorative coverings may be easily repositioned during installation, and after installation, one or more decorative coverings may be removed and replaced to address wear and tear, or to change the appearance of the surface that is covered. The present disclosure provides methods and tools for encouraging the installed decorative coverings to fit more closely with one another. This is achieved by biasing or tensioning the hook and loop attachment as described herein. This may reduce the occurrence of unsightly gaps between the decorative coverings, and, to the extent that adjacent decorative coverings abut one another, such installation may also inhibit the passage of foreign elements such as dust, and possibly liquids, between the decorative coverings.
Surface covering elements 22, such as vinyl planks, may be provided with loops 24 (as illustrated in
Decorative elements may also have different or complimentary geometric shapes. The shapes may also be irregular or non-uniform so long as adjacent decorative elements may be installed according to the method described herein. An example of irregular decorative elements is illustrated in
For example, a typical hook sheet might be between a sixteenth of an inch and three quarters of an inch thick, and a typical decorative element may have similar dimensions. However, thinner and thicker decorative elements and hook sheets may be employed. When a hook sheet with integral stems is used, the stems may be one millimeter high and 0.55 millimeter in diameter. The hooks (and sheet) may be made of polypropylene. The ratio of stem height to diameter is preferably about 2:1, and may be as great as 10:1. The stem diameter may be in the general range of 0.3 to about 0.9 millimeters. Stem diameters of as small as 0.1 millimeter may be acceptable.
Decorative elements, such as luxury vinyl tile that are typically used without hook and loop attachment may be converted simply by adding hooks and loops, as appropriate. Alternatively, decorative covering elements may be specifically manufactured to take advantage of the hook and loop attachment systems. For instance, such decorative coverings may be manufactured to have less rigidity because the hook surface or hook sheets will also contribute to the overall rigidity of the floor covering.
Decorative element 38 may be identical to decorative element 22, but it need not be. For example, decorative element 22 may be a wooden or vinyl floor plank, whereas decorative element 38 may be made of ceramic or some other material. It is preferable that corresponding edges 22a and 38a of decorative elements 22 and 38 are generally congruent to one another (as shown in
Decorative element 38 may be placed upon one or more anchor sheets 26 so that at least some loops of decorative element 38 are caught or retained by one or more hooks 32. Unlike the installation of decorative element 22, decorative element 38 is installed so that it overlaps decorative element 22, preferably along an edge thereof. The amount of overlap “B” is preferably similar to a length “L” of a loop 24.
a presents an isolated view of a loop 24.
Overlap “B” may be calculated based upon the length and resilience of loop 24 and the desired force of abutment between decorative elements 38 and 22. For example, overlap “B” may be similar to distance “L”, particularly if many loops 24 are compressed or bent adjacent to the substrate 25 to which loop 24 is attached. An overlap “B” in the range of L+M, or L+M+N may also be selected, depending upon the resiliency of loops 24 and the requirements of the installation (e.g., closely abutting decorative elements).
Accordingly, to the extent that loops 24 (or hooks 32) also have elasticity or resiliency, the overlap “B” may be greater. In an embodiment, overlap “B” may be between about one millimetre and thirty millimetres and might also be in the range of two millimetres to ten millimeters. An overlap “B” of about 2 to 3 millimetres has been found to be effective. In the present example, overlap “B” is about 2 millimetres.
The amount of overlap “B” may be determined by a measurement of the maximum extension of the possible movement between the decorative element 38 and field of hooks 20, when at least some of the respective hooks 32 and loops 24 of decorative element 38 and field of hooks 20 engage. For example, this may be done by placing (in direction “A”) decorative element 38 upon a field of hooks 20 and then applying a force, for example, in direction “C”. The maximum relative displacement of decorative element 38 may be used as overlap “B”. Overlap “B” is preferably less than or equal to such maximum extent of movement.
For example, in an embodiment, decorative element 38 can move by two millimeters when at least partially attached and generally parallel to field of hooks 20. Accordingly, overlap “B” is preferably about two millimeters or less. The closer that overlap “B” is to the maximum relative movement, the greater the likelihood that decorative element 38 will exert force against decorative element 22 once installed. If loops 24 are not resilient, overlap “B” will typically be less and a force exerted by decorative element 38 upon decorative element 22 may be less. In this example, loops are manufactured by stitching polyester yarn (to form the loops) through a polypropylene layer using a malimo process. Such loops are manufactured by Scott & Fyfe in Scotland under part number 40/film. Suitable loops made by other manufactures and with other materials may also be suitable. For example, fleece or “fluffy” materials may be suitable. The hooks are mushroom shaped and may have the following approximate dimensions: 0.5 mm diameter; 0.6 mm length; and 0.9 mm head.
Even if a force is not exerted, an overlap “B” may be used to at least reduce the amount of play in decorative element 38 relative to field of hooks 20.
To install decorative element 38, a force is applied to decorative 38. Force is applied in the region of the overlap to (i) cause decorative element 38 to become generally co-planer with decorative element 22, and (ii) to enable at least one loop 24 that is free to engage a hook 32. For decorative elements 38 made of more rigid materials, the force applied may be in the general direction “C”. The force is applied in general direction “C” until overlap “B” is reduced or eliminated. A force may then be applied in the general direction “A”. It must be emphasized that the particular direction that decorative element 38 is moved need not be precise, as long as the overlap area “B” is eliminated, and decorative element 38 is permitted to become somewhat co-planer with decorative element 32.
For less rigid decorative elements, a force in a combined direction A+C may be applied, where the particular force component A or C may be different, or varied. When relatively resilient luxury vinyl tile is used for decorative element 38, a quick blunt force applied in the general direction “A” to the overlap area “B” can serve to quickly place decorative element 38 into the desired alignment (as shown in
The amount of force and the manner in which it is applied may vary depending on the material used for decorative element 38. For example, if a resilient material is used, then a blunt instrument such as a hammer or a rigid brick-like structure, or some other suitable element, may be used without damaging the decorative coverings 38 and 22. Padding may be applied to any tool (or hand) used to apply the force in order to reduce damage to the decorative element. Similarly, protective padding may be applied onto any area of a decorative covering that receives a force. For some installations, it may be possible to simply apply the force to decorative element 38 by hand. However, this may not be as efficient as using a tool. On the other hand, for particularly brittle or delicate floor coverings 38, hands or tools gently applied may be required to protect the covering.
Any force applied to decorative covering 38 may ideally be applied along the entire overlap area at once. Alternatively, force may be applied at two or more regions of the overlap area, either simultaneously or sequentially. For example, force may be applied at one end of the overlap area (see
As a force is applied to decorative element 38 to move it, loops 24 are caused to slide around respective hooks 32 and at least some of the loops become taut. Thus a tensioning or biasing force is created, encouraging the decorative element 38 to abut decorative element 22. This may reduce the extent of movement of decorative element 38 in general, and in particular, it may serve to reduce the extent of movement of decorative element 38 within the plane of decorative element 38. To the extent that loops 24 (or hooks 32) are resilient, applying additional force may stretch the loops 24 and/or hooks 32 to further inhibit movement of decorative element 38. This arrangement may also inhibit unintentional removal of the decorative elements 22 and 38.
If there is minimal or no resiliency in loops 24 (or hooks 32), then when decorative element 38 is brought into alignment with decorative element 22, the ability of decorative element 38 to move relative to field of hooks 20 may be reduced as compared to a decorative element installed in the manner of
If overlap “B” is made large relative to the length “L” of loops 24, or if it is made large relative to the resilient extent of loops 24, then additional energy may be stored in the loops 24 that initially engage hooks 32 when decorative element 38 is first placed upon field of hooks 20. This additional energy is stored when decorative element 38 is made co-planer with decorative element 22. As overlapped decorative element 38 is moved into place, loops 24 become taught around corresponding hooks 32. (If resilient loops are used then, loops 24 elastically stretch as additional force is applied to decorative element 38.) When decorative element 38 is aligned with decorative element 22, loops 24 that have been elongated and/or stretched, exert a force to encourage decorative element 38 towards decorative element 22 in a direction generally opposite to direction “C”. This may encourage decorative element 38 to abut decorative element 22. This abutment may reduce any unsightly gaps between decorative element 38 and 22. It may also reduce the ability for foreign and unwanted matter to pass between decorative elements 38 and 22. When sufficiently resilient loops 24 (and/or hooks 32) are used, the force exerted by decorative element 38 upon decorative element 22 may be sufficient to make the interface between the decorative elements resistant, or possibly even impermeable, to a liquid.
If decorative element 38 is not adequately aligned relative to decorative element 22, then a gap may still exist. It has been found that as additional decorative elements are added adjacent to the installed decorative elements, any gaps between previously installed decorative elements may be reduced or eliminated.
The described installation has the further advantage that, as the installed decorative elements (and other components) expand and contract due to environmental conditions, the play provided by the combined hook 32 and 24 arrangement, may accommodate some of such expansion and contraction, and may reduce the likelihood of the decorative elements to form gaps, or to cup or buckle.
Additional accommodation for excess stress within the components of the decorative covering and field of hooks may be obtained by use of hooked sheets 26 that are permitted to free float over, or have minimal attachment to, a surface such as a floor. For example, a gap “G” may be provided when hooked sheets 26 are laid upon a surface. Gap “G” may be as small as a fraction of a millimetre and may be as large as one centimetre or more, depending upon the nature of the surface element 22 and the intended use for the covering. In an embodiment, a gap “G” of about 2 millimetres may be used. Gap “G” may permit movement of one or more hook sheets 26 as decorative element 38 is being installed. For example, if overlap area “B” is too large, and there is not enough play and/or resiliency within hooks 32 or loops 24 to permit installation of decorative element 38, then hooked sheets 26 may move to reduce or close gap “G” to permit installation of decorative element 38. Similarly, expansion and contraction of the various elements described due to environmental or other factors may be accommodated by gaps “G”. This may serve to reduce cupping, bending, and other deformations in the surface made up of decorative elements such as decorative elements 22 and 38. Gaps “G” may affect the calculation of the preferred overlap “B”, because the gaps may permit additional movement of portions of hooked surface 20, particularly when a decorative element 38 spans a gap “G”.
Alternative hook sheets 40 may be employed to permit movement of hook sheets relative to one another. Such hook sheets may have overlapping expansion areas about portions 42 and 44. Hook sheets that include this configuration are illustrated in
As noted above, the various components described, when installed, tend to be nearly flush with one another. Any gaps or spaces shown in the figures are exaggerated for illustration and ease of explanation. Similarly, the field of hooks 20 and hook sheets 26 forming a field of hooks 20 are sometimes illustrated in the figures with hooks missing in an area or with hooks missing about the edges or perimeter. This is done for ease of illustration or may be done for ease of manufacture. However, hooks may be included over the entire surface, or strategically placed upon select portions of a surface to be covered to enable decorative elements to be installed in a manner described herein.
In the foregoing embodiments an overlap has been used to permit the engagement and tensioning of connected hooks and loops to encourage decorative element 38 to be retained by surface 20, and to encourage abutment of decorative element 38 against decorative element 22. In another embodiment, a fixed feature (not shown) such as a piece of wood nailed or glued to a surface may be used instead of decorative element 22 (at least for the installation of a first decorative element 38, or row of decorative elements 38). In this embodiment, decorative element 38 is overlapped with the fixed feature, and installed as described above.
In a further alternative embodiment, decorative element 38 is placed upon surface 20 in general direction “A”. A force generally parallel to surface 20 may be applied to decorative element 38. This force may cause decorative element 38 to become displaced, and loops 24 (and possibly hooks 32) to be elongated or stretched in the manner described herein. Once decorative element 38 is displaced by a desired amount, it may be held generally in place by placing decorative element 24 in abutting relationship to it. Any resilience in loops 24 (or hooks 32) may cause marginal displacement of decorative element 24. In this embodiment, a similar abutting relationship is achieved to that described for when decorative covering 38 is installed by overlapping it. Decorative element 38 may alternatively be held in place, once moved, by something other than decorative element 22. In this embodiment, decorative element 38 may be moved by hand or by employing a tool having a slip resistant surface.
Template 48 is illustrated having a straight edge. This is done so that it conforms to an edge such as edge 22a of a decorative element 22. If decorative element 22 has a curved edge, or an irregular edge, then template 48 may be configured accordingly.
In an alternative embodiment, a template congruent to but smaller than the decorative element 38 may be placed on the surface 20. Decorative elements 24 may then be placed adjacent the perimeter of the template. The template may then be removed to reveal an exposed area of surface 20 that is marginally smaller than decorative element 38. Decorative element 38 may then be placed within the exposed area with one or more edges overlapping a respective decorative element 24. Each overlap may then be removed employing the method described above.
a illustrates the installation of decorative elements 62 and 64 having cooperating tongues and grooves. Decorative element 64 having an exposed tongue or groove may be installed in the manner described above. Decorative element 62 having the other of a tongue and a groove may be installed using a sheet 66 that has at least one surface that does not engage hooks 32. Such surface is placed against hooks 32. A thickness of sheet 66 may correspond to a distance between decorative element 64 and field of hooks 20.
Decorative element 62 is installed by first placing sheet 66 upon field of hooks 20. Decorative element 62 may then be slid into position by applying a force in the general direction “H”. Sheet 66 is then removed. While this installation method may not provide significant biasing of decorative element 62 against decorative element 64, it enables the positioning of the tongue within the groove to inhibit passage of foreign matter, and to reduce the occurrence of gaps between decorative elements.
As noted,
Decorative elements may also be attached to a field of hooks independently in order to form modules that may be installed to cover a surface.
As illustrated in
As shown in
Decorative covering 74 and hook sheet 70 are preferably offset along at least one edge. This permits the combined module formed by the decorative covering and the hook sheet to be attached to like decorative coverings and hook sheets as shown in
While it is preferred that decorative element 74 is somewhat flexible. A more rigid decorative element, for example, made of wood, may be used with some benefit. When a stiff decorative element is used, bending of hook sheet 70 should be minimal to encourage at least a few hooks and loops to engage. Once hook sheet 70 is flattened, some tensioning of previously engaged hooks and loops may provide improved securement of the rigid decorative element to the hook sheet.
While the foregoing embodiments of the invention have been described in some detail for purposes of clarity and understanding, it will be appreciated by one skilled in the art, that numerous modifications, variations, and adaptations may be made to the particular embodiments of the invention described above without departing from the scope of the invention, which is defined in the following claims.
