Embodiments disclosed herein include cordless window and architectural passage coverings. In particular, in one embodiment, a covering incorporates a separate sheet of material attached at one end to a roller, and at the other end to the covering, whereby the sheet of material extends and retracts the covering from an architectural passage. Moreover, in one embodiment, guide members may be attached to a covering by which the separate sheet of material passes through such guide members, wherein as the sheet is drawn upwards through the guide members, the guide members stack in an accordion fashion and raise the covering upwardly into folded layers of a roman shade. Additionally, in one embodiment, a pull cord guide that can be retro fitted to existing shades to avoid having a hazardous loop is disclosed.
In the use of window and architectural passage coverings, the art has long relied on cords, string or the like to extend and retract the coverings. Such coverings take many forms, including shades such as curtains, roll-up shades, Venetian blinds, vertical blinds, cellular shades, and the like. The problem with such coverings that rely on cords is that small children can become entangled in the cords and experience serious harm, including strangulation and death. On Aug. 26, 2009, the U.S. Consumer Product Safety Commission announced a voluntary recall of all ¼ inch Oval Roll-up Blinds and Woolrich Roman Shades, including some 4.2 million roll-up blinds and 600,000 Roman shades, (http://www.cpsc.gov/cpscpub/prerel/prhtml09/09324.html). The Commission referenced the hazard that “[s]trangulations can occur if the lifting loops slide off the side of the blind and a child's neck becomes entangled on the free-standing loop or if a child places his/her neck between the lifting loop and the roll-up blind material.” Recent cited injuries include a report that “[i]n November 2007, a 1-year-old boy from Norridgewock, Me. became entangled and strangled in the lift cord loop of a roll-up blind that had fallen into his portable crib. In October 2008, a 13-month-old boy from Conway, Ark. was found with his head between the exposed inner cord and the cloth on the backside of a Roman shade. The cord was not looped around the boy's neck but rather ran from ear to ear and strangled the child.” Numerous manufacturers and retailers have followed their call. Additional information may be found at: (http://www.windowcoverings.org).
In addition to the internal cords attached to the shade or blinds that can be pulled out and pose a problem, the pull cords, string and beaded cords in mechanical based blinds and shades that are pulled on to draw up the blinds or shades also pose a risk since they also create a hazardous loop of sufficient diameter (12 inches per the Consumer Product Safety Commission) for a small child to get their head tangled inside. Even the retrofit devices currently available (http://www.windowcoverings.org/how_to_retrofit.html) do not eliminate the hazardous loops created by the beaded cords even if they are tied to the wall with a tie-down device such as a Rollease™ product or with separated draw strings and/or cord stops that could still become tangled together to create a hazardous loop.
U.S. Pat. No. 7,624,784 to Anthony, et al. (hereinafter “Anthony”) discloses a segmented roll-up covering with a plurality of roller assemblies utilized to form panels wherein each roller assembly includes a strip of flexible lift sheet material and an associated roller about which the material can be wrapped. One edge of the lift sheet material is fixed to a relatively rigid bar or is otherwise supported while the opposite edge is secured to its associated roller. The roller with the lift sheet material secured thereto is cradled in one of a plurality of cradles provided in a first lift system which includes a cord ladder or similar structure so that upon movement of one vertical run of the cord ladder between an elevated and a lowered position while the other vertical run remains stationary, the cradle is raised or lowered thereby lifting or lowering the roller causing it to roll and either roll the fabric thereabout or unroll the fabric there from depending upon the direction of rotational movement of the roller. One problem with this system is that the lift system is enabled by a cord ladder, which as mentioned above, can pose a danger to small children.
There have been attempts to create cordless coverings in the art. One example is U.S. Pat. No. 7,036,547 to Cheng, et al. (hereinafter “Cheng”) discloses an assembly that includes a shade capable of height adjustment, comprising a shade with multiple pleats, a roller, a strap that extends through multiple pleats of the assembly, and at least one strap operatively connected with the roller to be raised and lowered as the height of the shade is increased or decreased. While Cheng discloses a cordless lift mechanism, the lift mechanism disclosed involves straps or narrow ribbons of fabric that would not reduce the strangulation risk to a child. In addition, the straps are threaded through the shade, exposing holes by which light can pass through the shade. Moreover, the straps are not sufficient to hold heavy shades, curtains and the like.
U.S. Published Patent Application No. 20050109468 to Hsu (hereinafter “Hsu”) discloses a cordless blind structure that includes a blind body attached to the underside of an upper beam, and a plurality of magnet components of elongated bars or blocks equidistantly distributed from the bottom-most slat upward to the top of the blind body. Hsu's system includes magnet components fixed to the outer surface of the blind body that acts as a cordless lift mechanism wherein the magnet components are consecutively lifted upwards and sequentially piled up in order to fold up the slats of the blind body. To unfold the blind body, the blind body is pulled slightly downwards by the bottom-most slat to detach the engaged magnet components from one another, releasing the collected blind body to suspend downwards. One drawback to the system of Hsu is the requirement of having expensive and likely heavy magnets capable of holding the weight of the blind or sacrificing weight for security that precludes the use of such system with heavier coverings such as shades, curtains and the like. Moreover, the system of Hsu fails to include guiding members to assure that the blind is folded properly.
U.S. Pat. No. 5,706,876 to Lysyj (hereinafter “Lysyj”) discloses a cordless, cellular window shade that uses a conventional roller shade bar to raise and lower transversely spaced tapes that extend through slits in the cellular fabric and are secured to the bottom rail of the shade. The deficiencies of the Cheng shade assembly are also present in the shade disclosed in Lysyj.
U.S. Pat. No. 5,273,096 to Thomsen et al. (hereinafter “Thomsen”) discloses an apparatus for gripping lengths of sheet material in a foldable blind or shade, in a blind that is composed of one continuous piece of fabric. Tubular members having longitudinal openings therein which accept the sheet material through grooves are described. Rod members also fit within the tubular members, to hold the sheet material between the tubular members and the rod members. Guide means are arranged to guide pull cords, and engage a longitudinal groove in each tubular member. Thomsen discloses a powered lift mechanism, but only exemplifies shades that include corded lift mechanisms that do not eliminate the risk of strangulation.
In consequence, the art is in need of improvement in coverings for architectural openings that maintains the functionality and aesthetics of previously developed coverings, but avoids their deficiencies, particularly their hazardous character as regards the risk of injury or death associated with the use of cord arrangements. The art also is in need of a new mechanism to drive the lifting mechanism of shades and blinds that avoids creating a hazardous loop.
Embodiments disclosed in the present description relate to cordless coverings for an architectural opening, such as a window, door, portal, or the like. In one embodiment, a cord loop enclosure for shades and blinds is disclosed and is configured to replace the looped beaded cords pull cords, and strings that drive a rolling mechanism to draw up the blinds or shade.
In one embodiment, a shade with a cordless lift mechanism is disclosed that comprises a roller, guide members or looped bars, and an inner and outer material, e.g., fabric material. In another aspect, the material can comprise any woven or non woven sheet or web of lift sheet material, or film or sheet material, with the first inner lift sheet material connected at one end to the roller and at the other end engaged in some manner to the outer material.
In one embodiment, the second outer material or decorative shade itself is secured at an upper end portion to a support member. The support member can be any well known construction of material that houses a rolling mechanism to draw up the shade, e.g., wherein the support member is attached to a wall above an architectural opening. The support member can for example comprise a box or rectangular-shaped panel that is covered with decorative fabric matching that of the shade or second material.
In various further implementations, the first or inner material behind the shade is generally hidden from view and is engaged with the bottom of the shade material, such that the first guide or lift sheet material is drawn up by the roller, thereby pulling from the bottom the bottom of the shade material. Alignment may be maintained during the raising and lowering of the shade by the use of guide members that can be attached to the shade, which maintain alignment and also allow for pleated stacking of the shade as the inner lift sheet material pulls on the bottom of the shade material, but which itself has its movement restricted to being close to the shade material by the guide members. As the lift sheet material is drawn up, the guide members that enclose the lift sheet material may be sequentially spaced along the shade material and begin stacking together to force the shade material to fold like an accordion as the shade is drawn up.
A further aspect to a cordless lift system comprising a monitoring assembly adapted to stop the first material from being wound about the roller, when stress, load or strain exceeding a predetermined value is sensed by the monitoring assembly as being exerted on a location or component of the covering.
In another aspect, looped guide bars may be arranged horizontally and attached to an outer shade material at regular vertical intervals, with the inner lift sheet material threaded through the loop formed by the guide bars. The inner material or “roller shade” slides freely through the guide bars as the shade is rolled up without the use of a cord to “pull” up the shade. In this manner, the covering system provides a cordless lift mechanism that does not present the risk of child strangulation prevalent in shades that use corded lift mechanisms. The inner lift sheet material can be attached at or near the bottom of the lift sheet material at or near the bottom of the shade material, or can have some engaging elements such as magnetic strips, Velcro® fastener tapes, or an elongated bar sewn into the bottom of the inner lift sheet material that is of a greater length than the inner lift sheet material and of a greater length than the space between the two loops of the guide members that are positioned at spaced intervals along the vertical extent of the shade, such that the bar collects each guide member from the bottom up as the inner guide shade is raised to raise the outer shade material in the same stacked accordion fashion.
In implementations in which magnetic strips are employed as engaging elements, the magnetic strips are preferably weight sensitive to weight levels of around 8 pounds, or more or less, such that if a child were able to separate the inner lift sheet material from the guides, leaving the inner lift sheet material nonetheless attached to the shade material and crawling between them, the weight of the child would break the magnetic bond, opening the inner and outer materials to release the child from any otherwise hazardous confinement. Likewise, Velcro® fastener tapes can be used that are weight sensitive in character, so that respective tape members disengage from one another when the engaged strips are subjected to a separational weight thereon, e.g., of 8 pounds or less, or alternatively of 8 pounds or more.
In one embodiment, the invention relates to a cordless shade lift system is disclosed that can include a roller in one of a number of functional styles, including a conventional clutch mechanism with a loop pull cord that could be tied out of reach of small children or that can be encased within a loop cord enclosure, a spring loaded roller that enables manual raising or lowering, a gravity free rolling mechanism for easy specific positioning at any desired level, or a motorized mechanism for automatic raising or lowering.
In the motorized shade systems, an additional torsion based safety mechanism or safety clutch commonly known in the art can be arranged such that when the motorized system recognizes strain exceeding a predetermined value on the system, the motorized system will shut down and not raise the shade. Thus, the shade is not drawn up if for example a child manages to crawl into any potential pocket created at or near the bottom of the first lift sheet material as attached to the second shade material. Such a system can be combined with the bar, magnetic connector, or Velcro® hook and loop fastener system described above to further insure that a child would not get drawn up into the shade should they be able to insert themselves into a pocket created between the first lift sheet material and the second shade material.
In one embodiment, a cordless shade lift system inner material or “roller shade,” is disclosed which may include a mesh or similar extension attached to the bottom end that incorporates a weighted dowel to “square” the shade. The material would ideally not be so thin and of such short width to allow the material to be bunched up creating a dangerous loop.
In one embodiment, guide members or continuous loops may be attached to a shade material to make a continuous loop around the inner lift sheet material of the lift system, such that the inner material is pulled up through the guide members thereby successively stacking (upwardly in a bottom up progression) the guide members as the inner lift sheet material is pulled upwardly through the guide members.
In another embodiment, guide members or hooks are disclosed that only extend around the inner lift sheet material to a relatively short extent, e.g., by about a couple inches, but which are continuous across the shade material behind the inner lift sheet material, effectuating a same stacking of the shade as the inner lift sheet material is drawn up by the roller. These guide members would not create a complete loop as described above, but would instead allow for the lift sheet material to be pulled through the hooks on each of the (left and right) sides of the shade assembly, rather than being pulled all the way through the continuous loop guides. This system combined with an elongated guide bar attached to the lift sheet at or need the bottom would allow for an additional safety element such that the inner lift sheet could be pulled away from the decorative material to keep small children from getting stuck in any pockets created therein should they crawl between the lift sheet and decorative material.
In another embodiment, a covering for an architectural opening is disclosed which comprises: a support member; a roller secured to the support member; a first material having a proximal portion secured to the roller, whereby the first material can be wound about the roller or unwound there from; a second material having a proximal portion secured to the support member and a distal portion secured to a distal portion of the first material; and at least one guide member attached to the second material, whereby the at least one guide member guides the second material about the first material as the first material is wound about the roller or unwound there from.
In one embodiment, a shade kit is disclosed that can be readily assembled with ease, that comprises: a support member; a roller secured to the support member; a first (inner guide) material having a proximal portion secured to the roller, whereby the first material can be wound about the roller or unwound there from; a second (shade) material having a proximal portion secured to the support member and a distal portion secured to a distal portion of the first material; and at least one guide member attached to the second material, whereby the at least one guide member guides the second material about the first material as the first material is wound about the roller or unwound there from. The at least one guide member can in specific implementations comprise at least one straight rod adapted to be fitted on each end to U-shaped guide members spaced apart to sufficiently couple each end of the first material for alignment of the first material as it is drawn up by the roller. Alternatively, the at least one guide member could comprise two straight rods adapted to be fitted on each end with U-shaped guide members so as to form a complete loop around the first material.
In another embodiment, a system with a do-it-yourself kit is disclosed that comprises a support member; a roller secured to the support member; a first lift sheet (inner guide) material having a proximal portion secured to the roller, whereby the first material can be wound about the roller or unwound there from; a second (decorative shade) material having a proximal portion engaged with the support member and a distal portion secured to a distal portion of the first material, wherein the decorative shade is devoid of a liner, the need for which is obviated by the first lift sheet material; and at least one guide member attached to the second material, whereby the at least one guide member guides the second material about the first material as the first material is wound about the roller or unwound there from. The system may include U-shaped rings that easily fit on guide bars to create the guide members. The guide bars may have loops or holes in one or more places for sewing to the decorative shade, or may be attached within a pocket created by or on the back of the decorative shade and/or with a Ronco® button fastener or rivets allowing for easy attachment. The decorative shade itself can be readily clamped, fastened or attached at one end to the support member and engaged at a different section to the lift sheet material.
In one embodiment, a covering as described above is disclosed, wherein the at least one guide member comprises a plurality of guide members attached at intervals along the second material, that fold the second material into an accordion folded compacted form when the first material is wound about the roller.
In another embodiment, a cordless cover system for an architectural opening is disclosed, comprising: a support member; a rolling mechanism secured to the support member; a first material having a proximal portion secured to the rolling mechanism, whereby the first material can be wound about the roller or unwound there from; a second material having a proximal portion secured to the support member and a distal portion secured to a distal portion of the first material; and at least one guide member attached to the second material, whereby the at least one guide member guides the second material about the first material as the first material is wound about the rolling mechanism or unwound there from.
In a further embodiment, a method of making a cordless cover for an architectural opening is disclosed, comprising: providing a support member; attaching a rolling mechanism to the support member; attaching a first material at a proximal location of said first material to the rolling mechanism, whereby the first material can be wound about the roller or unwound there from; attaching a second material at a proximal location of said second material to the support member; attaching a distal location of said second material to a distal location of said first material; and attaching at least one guide member to the second material, whereby the at least one guide member guides the second material about the first material as the first material is wound about the rolling mechanism or unwound there from.
Also disclosed is a cordless covering system, comprising a covering sheet suspended or suspendable from a support and secured at its lower end portion to a lower end portion of a lifting sheet that is joined at its upper end to a lifting and lowering apparatus, with guide structure that couples the covering sheet with the lifting sheet so as to enable the lifting sheet during lifting thereof to compact the covering sheet into an upwardly compacted form, and during lowering thereof to release the covering sheet from its upwardly compacted form to a downwardly extending sheet conformation.
In one aspect of such cordless covering system, the guide structure comprises laterally extending guide members coupled to the covering sheet and engaging the lifting sheet at edge portions thereof.
In another aspect, the lifting sheet has secured to a distal end thereof a laterally extending bar that engages the guide structure to effect folding of the covering sheet into an accordion-folded compacted form when said lifting sheet is lifted.
In another embodiment, a cordless covering system is disclosed, wherein the covering sheet and lifting sheet are secured to one another at their distal portions by matably engageable securement elements on each of said distal portions.
The cordless covering system in a further aspect comprises a monitoring assembly adapted to stop the lifting sheet from being lifted when stress, load or strain exceeding a predetermined value is sensed by the monitoring assembly as being exerted on a location or component of the cordless shade system.
In another aspect, the cordless covering system comprises a motor arranged to reversibly raise or lower the lifting sheet.
In another aspect, a loop cord control enclosure is disclosed to encase a looped cord attached to the shade or blind system at the top to drive the rolling mechanism that raises and lowers a shade or blinds. The cord is encassed to protect any hazardous loops from being exposed, and exposes the cord on each side of a shaft to allow an operator to draw the cord and shade/blind up and down. The mechanism is adapted to be retrofitted onto an existing shade or originally fit on any of the systems described above. In one embodiment, the loop cord enclosure is attached at the roller at the top, has the cord encased in an enclosure with two channels (also called “cord tracks”) to keep each loop separate, has the cord exposed in the middle on each side of a shaft, and is again enclosed at the bottom all the way to a pully wheel. In another embodiment, that pully wheel at the bottom may alternatively be a spring tension mechanism or a weight to keep the cord taut.
In another aspect, a cord channel enclosure may completely enclose the cord and utilize a slider to actuate the cord within the cord channel enclosure.
Other aspects, features and embodiments will be more fully apparent from the ensuing disclosure and appended claims.
Those skilled in the art will appreciate the scope of the present disclosure and realize additional aspects thereof after reading the following detailed description of the preferred embodiments in association with the accompanying drawing figures.
The accompanying drawing figures incorporated in and forming a part of this specification illustrate several aspects of the disclosure, and together with the description serve to explain the principles of the disclosure.
The embodiments set forth below represent the necessary information to enable those skilled in the art to practice the embodiments and illustrate the best mode of practicing the embodiments. Upon reading the following description in light of the accompanying drawing figures, those skilled in the art will understand the concepts of the disclosure and will recognize applications of these concepts not particularly addressed herein. It should be understood that these concepts and applications fall within the scope of the disclosure and the accompanying claims.
Embodiments disclosed in the present Specification relate to a cordless covering for an architectural opening, such as a window, door or the like.
The advantages and features of the embodiments disclosed herein are further illustrated with reference to the following disclosure, which is not to be construed as in any way limiting the scope of the invention but rather as illustrative of the invention in a specific application thereof.
In one embodiment, the cordless covering system is schematically depicted in
The flexible lift sheet material 105 can be any woven or non-woven material, fabric or the like that is strong enough to raise the decorative shade material 102 from the end thereof opposite the end that is attached to the support member 100. Ideally, the decorative shade material 102 will have one or more guide members 104 that allow the flexible inner lift sheet material 105 to pass through as it is raised or lowered by a roller 101. The decorative shade material 102 is attached, e.g., sewn, bonded or otherwise removably or non-removably secured to the guide members at one or more attachment points 103.
In the illustrated embodiment, the attachment point 103 is a simple circular eyelet at each end of the guide member 104. As the roller 101 begins rotating in a direction that draws in the lift sheet material 105, the lift sheet material 105 attached at the bottom to the shade 102 begins pulling on the shade until the very bottom guide member 104 starts being raised. The lift sheet material 105 passes through the guide member 104, drawing up the bottom guide member 104 and shade 102 that are attached to one another at attachment point 103 until the bottom guide member 104 reaches the next highest guide member 104 from the bottom. This process continues as the guide members 104 are drawn together like an accordion to form a compacted folded conformation 106 as shown in
The guide members 104 are advantageously selected to be strong enough to handle the weight of the entire shade 102 along with any other guide members 104 drawn up by the lift sheet material 105, but light enough not to cause excessive strain on the roller 101. The guide members 104, including guide rods 108 and end clips or U-shaped brackets 107, can be made of any suitable metal, plastic, polymer, acrylic, or other material, and may be formed by extrusion, injection molding, machining, casting, forging, etc. One advantageous embodiment includes metal guide rods 108 and injection molded end clips or brackets 107. The guide members 104 can form an entire loop shape with two equal length bars 108 capped on each end with U-shaped ends 107 to constitute a complete loop around the lift sheet material 105. Such U-shaped end caps 107 might ideally have female connectors to allow coupling to male ends on the guide rods 108 for ease of installation. The guide members could also merely comprise one guide shaft 108 attached to the shade 102 with hook or U-shaped brackets 107 on each end of each guide shaft 108 to sufficiently couple the lift sheet material 105 as for example is shown in
Likewise, the attachment points 103 are advantageously strong enough to attach the guide members 104 to the shade 102 in any number of ways, including attachment with sew holes, rivets, button fasteners or the like. Additionally, the guide shafts or rods 108 of the guide members may be rectangular in profile or cylindrical with a flat surface or 2 flat surfaces, e.g., with a profile of ⅜″× 3/16″ and having any suitable length. Alternatively, or in addition, the guide rods 108 can include small sew holes spaced along the length of the rod, to allow the decorative shade 102 to be sewn to or otherwise attached in a secure manner to the guide members 104.
Although the shade 102 is described in reference to a window shade or covering, it is to be understood that such a structure can be used in conjunction with any type of opening, including architectural openings such as doors, hatches, portals, entry ways and the like.
The cordless covering system of
Thus, in one embodiment, a cover is disclosed that comprises a crank mechanism that is manually actuatable to wind the lift sheet about the roller or to unwind the lift sheet from the roller. Such crank mechanism may be mechanically coupled to the roller for rotation thereof in either of a first rotation direction or a second rotation direction opposite to the first rotation direction. The crank mechanism may be mechanically coupled to the roller by any suitable coupling structure, such as for example a beaded chain that is mounted inside a channel member. The dual or single channel enclosure 117 may take on many forms, including having an exposed cord that ideally won't create a hazardous loop of 12 inches or more in diameter.
Such a system is disclosed in
Referring now to
In this embodiment, an actuating component 176 is received within a depression 178 defined by the slider 130. A shaft 180 connects the actuating component 176 to the cord engagement member 172 and the cord disengagement component 174. In this manner, turning the actuating component 176 clockwise and counterclockwise within the depression 178 also turns the cord engagement member 172 and the cord disengagement component 174.
Referring now to
The cord disengagement component 174 may also disengage the engagement end 193 from the cord 142 and also serve to snap the cord engagement member 172 and the actuation component 176 (shown in
In general, it may be desirable to have the lift sheet be a single panel article as opposed to vertically extending multiple strips laterally spaced apart from one another, since in the latter instance, the strips may bunch or otherwise become intertwined with one another, and may pose a safety hazard if a small child's arm or neck becomes entangled by such strips, if they are not arranged in a “breakaway” or disengageable relationship to the cover of the shade assembly. It typically is preferred to have the lift sheet extend laterally across a substantial portion of the back of the cover, and to have the lift sheet arranged for such breakaway disengagement of the lower end portion of the lift sheet from the cover.
Such laterally extended character of the lift sheet serves another purpose, of protecting the back of the decorative shade material, when the cover is formed of such material. This in turn can permit the cover to be “liner-less” since a lining layer of sheet material is not required, if the lift sheet extends substantially across the full extent of the cover.
In various embodiments, it is preferred to utilize guide members that extend only partly inwardly in a lateral direction, so that the guide members are arranged to “wrap around” the edge portions of the lift sheet, as shown in
It will therefore be recognized that embodiments of the cordless shade system disclosed herein can be constructed and arranged in any suitable manner, e.g., with a decorative sheet suspended or suspendable from a support and secured at its lower end portion to a lower end portion of a lifting sheet that is joined at its upper end to a lifting and lowering apparatus, with guide structure that couples the decorative sheet with the lifting sheet so as to enable the lifting sheet during lifting thereof to compact the decorative sheet into an upwardly compacted form, and during lowering thereof to release the decorative sheet from its upwardly compacted form to a downwardly extending sheet conformation.
Further, when the cordless shade system is deployed in a window, door or other opening, the lifting sheet itself may be decoratively appointed with a design, pattern, appliqué, silk-screened image, logo or other visual indicia, so that both faces of the shade system have an aesthetic or otherwise suitable visual appearance.
Although the embodiments disclosed herein have been illustratively described with respect to various embodiments for window openings or other architectural openings, it will be recognized that the cover assembly can be advantageously utilized as a covering for any indoor or outdoor passage, portal, gate opening or the like. For example, the cover assembly in other embodiments can be used as a closure for a tent or cabana or a decorative screen or partition that may be deployed with an associated frame, to provide a freestanding room divider, privacy screen, sun-blocking structure or the like.
While the embodiments disclosed herein have been described herein in reference to specific aspects, features and illustrative embodiments, it will be appreciated that the utility of the invention is not thus limited, but rather extends to and encompasses numerous other variations, modifications and alternative embodiments, as will suggest themselves to those of ordinary skill in the field of the present invention, based on the disclosure herein. Correspondingly, the invention as hereinafter claimed is intended to be broadly construed and interpreted, as including all such variations, modifications and alternative embodiments, within its spirit and scope.
Those skilled in the art will recognize improvements and modifications to the preferred embodiments of the present disclosure. All such improvements and modifications are considered within the scope of the concepts disclosed herein and the claims that follow.
