Each barrier is connectable to a pair of anchors, and when connected to respective anchors, extends linearly from the first strip to the second strip.

Description

RELATED APPLICATIONS

This application is a continuation-in-part of co-pending U.S. patent application Ser. No. 14/458,501 filed on Aug. 13, 2014, which claims priority to Danish patent application, PA 201400040, filed on Jan. 22, 2014, each assigned to the assignee of this instant application, the disclosure of each which is hereby incorporated by reference in its entirety.

FIELD

This disclosure generally relates to systems and method for forming protective barriers with fences. More particularly this disclosure relates to a railing system mounted to railings of a fence.

BACKGROUND

Homes, offices, buildings, and public or recreational areas (e.g., parks, bridges and the like) use fencing to form protective barriers for stairways, decks, balconies and the like. Such systems are useful for preventing children, pets and adults from unintentionally stepping into dangerous areas (e.g., a balcony or a bridge). Typically, such systems involve balusters (e.g., made of wood, metal, or plastic) mounted to railings. Several types of railing systems are known. In one example, the railing system has horizontal barriers extending between generally vertically-oriented railings. In such cases, children or pets may accidentally step on the horizontal barriers and endanger themselves. Vertical barriers on the other hand, prevent users from climbing on to the railing system. In some examples, at least a portion of the railing system can be partially transparent, so that the barriers provide a view past the fence. One type of vertical railing systems include metal balusters that are mounted separately to railings by bolting or welding. Other railings systems can include balusters made of wood or polymer materials that are mounted between wood or polymer moldings. For instance, the railing system may include pickets fastened (e.g., threaded, friction or press-fitted) in appropriate holes in the railings.
Conventional railing systems are bulky and have a labor-intensive assembly procedure. Additionally, if railings or balusters suffer damage (e.g., due to user negligence or accidents) removing and replacing damaged balusters can be time consuming. As conventional balusters are often fitted within holes in the railings, removing a single baluster can damage the railings and/or adjacent balusters. Thick balusters and pickets also block any views past them and lead to a cluttered and/or bulky look.

SUMMARY

Certain embodiments include a railing system for mounting to railings of a fence. The railing system can include a first strip and a second strip, each having a first surface and a generally planar second surface opposite the first surface. The first and second strips can be mounted to respective fence railings. Each second surface can face and engage a railing of a fence. The first and second strips can each define a length and a width and can have a thickness substantially less than the length or the width. The thickness of the first and second strips can be generally uniform along the length. The first and second strips can each have a plurality of openings extending therethrough.
In one embodiment, the railing system can include a plurality of anchors. Each anchor can have a leading edge, a shank and a flared portion. The leading edge and the shank can have a cross-sectional area less than a cross-sectional area of the respective opening to permit the leading edge and the shank to extend, in a direction from the second surface to the first surface, through a respective opening of one of the first or second strips. The flared portion can have a cross-sectional area greater than the cross-sectional area of the respective opening to prevent passage of the flared portion through the respective opening and anchor the anchor against the second surface of the one of the first and second strips.
In one embodiment, the railing system includes a plurality of elongated barriers. Each barrier can have a fixed length to extend from the first strip to the second strip when mounted to respective fence railings. Each barrier can have a first end and a second end. The first end can be connectable to one of the anchors when anchored to the first strip and the second end can be connectable to one of the anchors when anchored to the second strip. Each barrier, when connected to respective anchors, can extend linearly from the first strip to the second strip.
In one embodiment, the railing system can include a plurality of sleeves. Each sleeve can be connectable with the shank of a respective anchor. Each sleeve can have a hollow portion. In such cases, the first and second ends of each barrier can be receivable by the hollow portion of a respective sleeve. The first end can be connectable to the first strip and the second end can be connectable to the second strip when received by the hollow portion of a respective sleeve. Each barrier, when connected to respective strips, can extend linearly from the first strip to the second strip.
Certain embodiments also include a method of mounting a railing system to railings of a fence. The method can involve the step of providing a railing system according to any of the embodiments disclosed herein. The anchor can be positioned on the first and second strips such that the leading edge and shank extend in a direction from the second surface to the first surface and the flared portion is prevented from passing through the respective opening so that the flared portion anchors the anchor against the second surface of the one of the first and second strips. The first and second strips can then be mounted to respective railings of the fence such that each second surface faces and engages a respective railing of a fence. The flared portions of each anchor can be captured between first or second strip and the respective railing when the first and second strips have engaged with respective railings. The shank of each anchor can be bent with respect to its flared portion to a desired angle. The first and second ends of each elongated barrier can then be to one of the anchors so that each barrier extends linearly from the first strip to the second strip.

DETAILED DESCRIPTION

The following detailed description is exemplary in nature and is not intended to limit the scope, applicability, or configuration of the invention in any way. Rather, the following description provides some practical illustrations for implementing exemplary embodiments. Examples of constructions, materials, dimensions, and manufacturing processes are provided for selected elements, and all other elements employ that which is known to those of ordinary skill in the field. Those skilled in the art will recognize that many of the noted examples have a variety of suitable alternatives.
Embodiments include a railing system for mounting to railings of a fence. The railing system can be mounted to existing railings of a fence quickly and without requiring many tools. Such systems provide a transparent fence allowing a user to be able see past the fence, and at the same time form protective barriers in the form of barriers that can easily be adjusted to ensure that they are securely mounted after installation. Such embodiments create aesthetically pleasing views suitable for use in many modern homes, offices and other buildings.
FIGS. 1 and 2 are perspective views of a railing system 10 according to an embodiment. As shown in FIGS. 1 and 2, the railing system 10 can be mounted to existing railings 110, 120, 130, 140 of a fence 100 for use in balconies, decks, stairways and the like. Alternatively, the railing system 10 can function as a stand-alone railing system 10 for use therein. As seen in the close-up perspective views of FIGS. 3 and 4A-4B, the railing system 10 includes a first strip 20 mounted on the existing railing 110 of a fence 100. Referring back to FIG. 2, a second strip 30 can be mounted to the existing railing 120 of the fence 100 opposite to the first strip 20. For instance, in one example, if the first strip 20 is mounted on the bottom railing 110 of the fence 100, the second strip 30 can be mounted on the top railing 120 of the fence 100. Alternatively, in other cases, the first and second strips 20, 30 can be mounted on the left and right side railings 130, 140 of the fence 100. In some exemplary embodiments, the first and second strips 20, 30 can be substantially similar in size and shape. Alternatively, the first and second strips 20, 30 can be of dissimilar sizes and shapes to allow them to be positioned on dissimilarly shaped railings (e.g., in balconies, decks, or inclined and/or spiral stairways). The first and second strips 20, 30 can be mounted flush (e.g., as shown in the view of FIGS. 11 and 12) against the railings 110, 120 to form a vertical, horizontal, angled or otherwise asymmetrically-oriented (e.g., spiral stairway) railing system 10.
FIGS. 5A-5C show various views of the first and second strips 20, 30 mounted to existing railings 110, 120 of a fence 100. As shown in FIGS. 5A-5C, the first and second strips 20, 30 each have a first surface 32 and a second surface 34 opposite the first surface 32. Each second surface 34 of the first and second strip 30 can engage (e.g., via fasteners 38, adhesives, etc.) a railing 110 or 120 of a fence 100. The first and second strips 20, 30 can be positioned and oriented such that they substantially conform to the orientation of the railings 110, 120 on which they are mounted. In one example, the second surface 34 can be generally planar (e.g., without any protrusions, bumps, or other surface projections) to facilitate mounting the first and/or second strips 20, 30 to a planar railing. Alternatively, in other examples, the second surface 34 can be curved or inclined to mount flush against a curved or angled railing. In the illustrated embodiments best seen in FIGS. 5A-5C, the first surface 32 faces away from the railing 110, 120 on which it is mounted, and the second surface 34 faces toward and/or is in opposition to the railing 110, 120 on which the first or second strip 30 is mounted. Additionally, as best shown in FIGS. 3 and 4A, the first surface 32 can either have tracks to capture other components (e.g., fasteners) to not protrude out of the first surface 32. Alternatively, the first surface 32 can be planar with uniform thickness (e.g., without any protrusions, bumps, or other surface projections).
The first and second strips 20, 30 can each be made of metals (e.g., aluminum, stainless steel, or other metals or alloys). As perhaps best seen in FIG. 5C, the first and second strips 20, 30 can each have a length “L”, a width “W” and a thickness “T”. The thickness “T” of the first and second strips 20, 30 can be generally uniform along their length “L”, as best seen in FIG. 10). Returning to FIGS. 5A-5C, in some cases, the thickness “T” can be uniform along the width “W”. The thickness “T” of the first and second strips 20, 30 can be substantially less than the length “L” or the width “W”, and the width “W” can be less than the length “L”, leading to a shallow and/or narrow profile of the first and second strips 20, 30 when mounted to existing railings of width and thickness greater than the width and thickness of the first and/or second strips 20, 30 respectively. The profile of the first and second strips 20, 30 facilitates the first and second strips 20, 30 from being substantially invisible when mounted on to existing railings 110, 120 of a fence 100, thereby providing aesthetically pleasing views suitable in modern homes and office buildings. Such systems also ensure that a limited quantity of materials is used in fabricating the first and second strips 20, 30, thereby lowering the cost of manufacturing the railing system 10.
In certain embodiments, the first and second strips 20, 30 can be of any desirable length “L” (e.g., between about one foot and about ten feet, and typically about three feet). When mounting to existing railings 110, 120 of a predetermined length, the first and second strips 20, 30 can then be cut to the predetermined length of the existing railing. The width “W” of the first and second strips 20, 30 can generally be less than the width of the existing railings 110, 120 on which the first and second strips 20, 30 are mounted. In one example, the width “W” of the first and second strips 20, 30 can be on the order of a few inches. The first and second strips 20, 30 can have any width (e.g., substantially equal to, or greater than, or less than the width of the railings 110, 120). As mentioned elsewhere herein, the thickness “T” is substantially less than the length “L” and the width “W” of the first and second strips 20, 30. The thickness “T” can be between about 1 millimeter and about 10 millimeters, and in some exemplary embodiments, is about 2 millimeters. Other ranges of thickness are also contemplated. In some cases, the railing system 10 can be provided with several strips of various standard dimensions (e.g., several lengths, widths and/or thicknesses as a kit) to mount to various types and geometries of railings 110, 120.
Referring back to FIGS. 4A-4B, the first and second strips 20, 30 each can have a plurality of openings 36 extending therethrough. As perhaps best seen in FIGS. 5A and 5C, the openings 36 can be equally spaced although they may have a non-uniform spacing. Each opening receives a fastener 38 (e.g., wood screws, nuts and bolts, push-connect or similar fasteners) to engage the first and second strips 20, 30 to the existing railings 110, 120 of the fence 100. In the cross-sectional view of FIG. 4B, the fastener 38 is a wood-screw. In this example, a user can engage the first and second strips 20, 30 to the existing railing of the fence by positioning the first and second strips 20, 30 to the railings 110, 120, respectively, positioning the plurality of fasteners 38 in the openings 36 of the first and second strips 20, 30, and then fastening the first and second strips 20, 30 to the railings 110, 120 (e.g., by driving the fasteners 38, via the plurality of openings 36, into the first and second railing via a power tool). Alternatively, any other fastener (e.g., hook and loop) known in the art can be used to engage the first and second strips 20, 30 to existing railing 110, 120. Alternatively, the first and second strips 20, 30 can be bonded (e.g., by welding, soldering, or using adhesives) to existing railing 110, 120.
Prior to positioning and engaging the first and second strips 20, 30 on the existing railings 110, 120, a plurality of anchors 40 may be inserted to openings 36 in the first and the second strip 30 to anchor 40 the first and second strips 20, 30 when engaged with the railings 110, 120. The anchors 40 may be positioned in the openings 36 in any configuration. In the embodiments illustrated in FIG. 5A-5B, each anchor 40 is placed in an opening 36 interspersed between openings 36 that receive a fastener 38. However, this may not be the case in other embodiments where anchors 40 are positioned in adjacent openings 36. As seen in FIG. 5D, each anchor 40 can have a leading edge 42, a shank 44 and a flared portion 46. The leading edge 42 and the shank 44 can have a cross-sectional area “A2” less than a cross-sectional area of the respective opening (not shown) of the first or second strip 30 to permit the leading edge 42 to be inserted into the opening. When inserted, the leading edge 42 and the shank 44 extend in a direction from the second surface 34 to the first surface 32, through a respective opening. The flared portion 46 can have a cross-sectional area “A1” greater than the cross-sectional area of the respective opening (not shown) of the first or second strip 30 to prevent passage of the flared portion 46 through the respective opening. The flared portion 46 anchors each anchor 40 against the second surface 34 of the one of the first and second strips 20, 30. In some embodiments, the flared portion 46 of the anchor 40 is beveled or chamfered to prevent sharp edged anchors. Any number of anchors 40 can be used, and in the illustrated embodiments shown in FIGS. 5A-5C, the spacing between the openings 36 receiving each anchor 40 is about one inch. While a uniformly spaced configuration of openings 36 is shown in FIGS. 5A-5C, the anchors 40 may be positioned in a staggered configuration e.g., in non-uniformly spaced openings 36).
With continued reference to FIGS. 5C and 5D, the leading edge 42 of each anchor 40 receives an elongated barrier 50. In some examples, the barrier 50 can be a filling. The elongated barrier 50 can have a fixed length to extend from the first strip 20 to the second strip 30 when mounted to respective fence railings 110, 120. Each barrier 50 can have a first end 52 and a second end 54. In one example, the first end 52 can be connectable to one of the anchors 40 extending from and/or anchored to the first strip 20 and the second end 54 can be connectable to one of the anchors 40 extending from and/or anchored to the second strip 30. Each barrier 50, when connected to respective anchors 40, can extend linearly from the first strip 20 to the second strip 30. While the embodiment illustrated in FIGS. 1-4B show the barriers 50 oriented in a generally vertical direction (e.g., as balusters), the barriers 50 can be oriented in any configuration. For example, the barriers 50 may be oriented horizontally, extending between the left side railing 130 and the right side railing 140 seen in FIGS. 1 and 2. Alternatively, the railings 110, 120 can be angled with respect to a horizontal or a vertical plane (e.g., the stairway railings shown in FIG. 6). In such cases, the barriers 50 can either be extending vertically as shown in FIG. 6, or can be inclined with respect to the horizontal or vertical plane, to form a protective fence for stairways.
In the embodiments illustrated in FIG. 5C, the barriers 50 are cylindrical with a diameter substantially less than their length. However, the barriers 50 can be of any shape (e.g., having a square, hexagonal, octagonal, or irregular cross-section when viewed in the length-wise direction). The barriers 50 can be of any length allowing them to extend linearly in any orientation (horizontal, vertical or angular orientation) between railings 110, 120. In some cases, the barriers 50 can have a length that equals the spacing between adjacent railings between which the barriers 50 extend linearly, when the railing system 10 is assembled (e.g., when the barriers 50 are anchored to the first and second strips 20, 30 via the plurality of anchors 40). In many cases, fences for balconies and stairways are of standard dimensions. For instance, the top and bottom railings (best seen in FIGS. 1 and 2) can be spaced apart by a distance of about 30 inches. In this example, the barriers 50 can have a length of about 30 inches to extend linearly and vertically between the top and bottom railings when assembled. Alternatively, if the barriers 50 are to be oriented in a horizontal configuration, they can have a length that equals the spacing between the left and right side railings shown in FIGS. 1 and 2.
With continued reference to FIGS. 1 and 2, in some exemplary embodiments, the barriers 50 can either be cables or rods. In embodiments wherein the barriers 50 are cables, the barriers 50 can be substantially flexible (e.g., with respect to the existing railings). In embodiments wherein the barriers 50 are rods, the barriers 50 are substantially rigid in comparison to the existing railings and/or first and second strips 20, 30. In such embodiments, the barriers 50 can be hollow or solid. The cable or rod can be pre-cut to a predetermined length. In some cases, the railing system 10 can be provided with several cables or rods of various standard dimensions (e.g., several lengths and diameters and/or thicknesses as a kit) and a user may cut (e.g., with a wire-stripper, saws, or other cutting tools) the cable or rod to the desired length. As mentioned elsewhere herein, many fences are of standard dimensions, wherein the spacing between adjacent railings 110, 120, 130 and 140 is known. In such cases, the predetermined length of the pre-cut rod or cable can equal the spacing between railings between which the barriers 50 can extend linearly when assembled. Alternatively, the user can cut the rod or the cable to any desired dimension. In some exemplary embodiments, when the railing system 10 is assembled (e.g., when the barriers 50 are anchored to the first and second strips 20, 30 via the plurality of anchors 40), the barriers 50 do not sag. For instance, the barriers 50 can be held in tension between the first and second strips 20, 30 by the plurality of anchors 40, such that the barriers 50 are substantially linear when anchored to the first and second strips 20, 30. Such barriers 50 can provide aesthetically pleasing fences for stairways, decks, and balconies (e.g., by allowing a view past the fence).
In some embodiments, the first and second ends 52, 54 of each barrier 50 have a stopper 60 to be received by or engage with an anchor. In some embodiments, the stopper 60 is integrally formed with the barrier 50. Alternatively, each stopper 60 can be fastened (e.g., threaded connection, with a fastener, or a complementary connector), or connected via a friction or press fit with the first and second ends 52, 54 of the barriers 50. Alternatively, each stopper 60 can be welded or adhered to the first and second ends 52, 54 of the barriers 50. In the embodiments illustrated in FIG. 4B, the stopper 60 is of cylindrical shape. Alternatively, the stopper 60 can be spherical (as illustrated in FIGS. 12-13B), cubical, or other shapes. In an exemplary embodiment illustrated in FIG. 4B, the stopper 60 can be sized such that it is received by an anchor 40 of the plurality of anchors 40. In the illustrated embodiment shown in FIG. 4B, at least a portion of the shank 44 of each anchor 40 is hollow. At least a portion of the hollow portion of each anchor 40 has an internal diameter greater than the external diameter of the stopper 60. In some embodiments, at least a portion of the hollow portion of each anchor 40 has an internally threaded portion for fastening the first barrier 50 to the first and second strips 20, 30. In such embodiments, the stopper 60 comprises an externally threaded portion engaging with the internally threaded portion of the anchor. While the illustrated embodiment in FIG. 4B shows the shank 44 having an internally threaded hollow portion and the stopper 60 having an externally threaded portion, the shank 44 of the anchor 40 and the stopper 60 can be configured such that the stopper 60 has an internally-threaded hollow portion for receiving an externally threaded portion of the shank 44 of the anchor. In such cases, the shank 44 may be hollow or solid. Other possible engagement between the anchor 40 and the stopper 60, such as a frictional or press fit, complementary connectors (e.g., via a dovetail joint), push-connect fasteners (e.g., flexible tabs, buttons, ribs, and the like which may be compressed and released to form a tight fit), and combinations thereof are also contemplated. Alternatively, non-releasable connection (e.g., bonding with an adhesive, welding or soldering the first and second ends 52, 54 with the anchors 40 once the barriers 50 are brought into contact with the anchors 40) between the anchors 40 and the first and second ends 52, 54 of the barriers 50 are also contemplated.
As mentioned elsewhere herein, the barriers 50 can be in a generally vertical orientation, a generally horizontal orientation, or in any angular orientation. In such embodiments, the first and second strips 20, 30 are in a generally horizontal orientation and the shank 44 of the anchors 40 extends in a direction generally perpendicular to the second surface 34 of the first and second strips 20, 30. Such embodiments are useful in constructing fences for balconies, deck, and the like. In some embodiments, the first and second strips 20, 30 are in a generally non-horizontal orientation. Such embodiments can be useful for constructing stairways, as illustrated in FIGS. 6-8.
In the illustrated embodiment shown in FIGS. 6 and 7, the first and second strips 20, 30 are placed in an angular orientation for a portion of the stairway, rather than in a horizontal orientation shown in FIGS. 1 and 2. In such cases where the first and second strips 20, 30 are in an angular orientation (e.g., at an angle “A” between about 1 degree and about 85 degrees, with respect to a horizontal plane, such as the treading surface 62 of the stairs), the barriers 50 can be horizontal, vertical or angled with respect to the railings 110, 120 and/or first and second strips 20, 30. In such embodiments, the shank 44 of each anchor 40 can extend in a direction non-perpendicular with respect to the second surface 34 of the first or second strip 30 through which the anchor 40 extends. For instance, the shank 44 can be bendable with respect to the flared portion 46 of each anchor. The shank 44 can be bendable (e.g., with a bending tool 80) such that it forms a desired angle with respect to the flared portion 46 and/or the second surface 34 of one of the first or second strips 20, 30 from which the anchor 40 extends. The shank 44 of the anchor 40 positioned on the other of the first or second strip 30 can also be bendable such that it forms a desired angle (e.g., between about 1 degree and about 85 degrees) with respect to the flared portion 46 and/or the second surface 34 of the other of the first or second strips 20, 30. The first and second ends 52, 54 of the barriers 50 can be connected to the angled shanks 44, thereby forming a fence with the barriers 50 in the desired orientation (e.g., horizontal, vertical, or angular).
FIGS. 8-14 show a railing system 10 with a plurality of barriers 50 according to another embodiment. In the illustrated embodiment best seen in FIGS. 13A-13B, the barriers 50 are cylindrical with a diameter “D” and a length “H”. Of course, any other cross-sectional shape of the barrier 50 (e.g., square, hexagonal, octagonal, rectangular, etc.) along the lengthwise direction is also contemplated. Each barrier 50 slidingly engages with a pair of sleeves 70. Alternatively, each barrier 50 can be fixedly coupled to a pair of sleeves 70. In such cases, the sleeves 70 can be positioned toward the first and second ends 52, 54 of each barrier 50. Each sleeve 70 can be connectable with the shank 44 of a respective anchor. Each sleeve 70 can have a hollow portion. In such embodiments, the first and second ends 52, 54 can be receivable by the hollow portion of a respective sleeve 70. Each sleeve 70 can be connectable with a respective anchor. Once connected, the engagement between the sleeves 70 and the anchors 40 facilitate anchoring the barriers 50 to the first and second strips 20, 30.
As mentioned previously, each barrier 50 includes a pair of stoppers 60 at its first and second ends 52, 54. In the illustrative (best seen embodiments in FIG. 12), the stoppers 60 are spherical, and can be welded to or integrally formed with (e.g., by molding if the barriers 50 are fabricated from polymer, by casting or machining if the barriers 50 are fabricated from metals) the barrier 50. In the illustrated embodiments shown in FIG. 12, the hollow portion of each sleeve 70 has an internal cross-sectional area (e.g., along its lengthwise direction) that is sufficiently greater than an external cross-sectional area of the stoppers 60, so that the stoppers 60 can be received by and/or pass through the hollow portion of the sleeve 70. For instance, if the sleeves 70 are cylindrical with an annular hollow portion, the internal diameter of the annulus can be greater than the external diameter of a cylindrical or spherical stopper 60. As shown in the illustrated embodiments, the barriers 50 typically have an outer cross-sectional area less than the outer cross-sectional area of the stoppers 60. The barriers 50 can therefore pass through the hollow portions of the sleeves 70, as illustrated in FIG. 8. The stoppers 60 can be seated in the anchors 40 as described previously (e.g., with respect to FIG. 4B) and the sleeves 70 can cover the stopper 60 and/or shank 44 of the anchor, as illustrated in FIGS. 9 and 11. Alternatively, the stoppers 60 can be received by and seated in the hollow portion of each sleeve 70.
Each sleeve 70 can engage with an anchor 40 extending from an opening of the first or second strip 30, and thereby connect each barrier 50 to the first and second strips 20, 30. As mentioned herein, the shank 44 of each anchor 40 in embodiments described herein can be bendable, as shown in FIG. 10 to orient the first and second strips 20, 30 and/or barriers 50 in any desired orientation (e.g., horizontal, vertical or angular orientations). In such cases, prior to engaging with the sleeve 70, the shank 44 of the anchor 40 can be bent (e.g., with a bending tool 80) to a desired angle (e.g., angle “B” as shown in FIG. 10). In some cases, the angle “B” can equal the angle “A” shown in FIG. 6. The sleeves 70 and anchors 40 can then engage by any known means. In one example, the sleeves 70 and anchors 40 can engage via a threaded connection. For instance (as shown in FIG. 14), each anchor 40 can have an externally threaded portion that can engage (e.g., by applying a torque) with an internally threaded portion of the sleeve 70. In such embodiments, the hollow portion of sleeve 70 can have internal threads for at least a portion of the length of the sleeve 70. Alternatively, the sleeve 70 can be externally threaded and can engage with an internally threaded portion of the anchor. In such embodiments, the anchor 40 can have a hollow portion comprising internal threads to receive and engage with the externally threaded portion of the sleeve 70. Alternatively, other known means such as frictional or press fit, complementary connectors (e.g., via a dovetail joint), push-connect fasteners (e.g., flexible tabs, buttons, ribs, and the like which may be compressed and released to form a tight fit), and combinations thereof are also contemplated. Alternatively, non-releasable connection (e.g., bonding with an adhesive, welding or soldering the sleeves 70 with the anchors 40 once the barriers 50 are brought into contact with the anchors 40) between the anchors 40 and the sleeves 70 are also contemplated.
In some cases, certain portions of the barrier 50 may sag when installed on natural or treated woods. The barrier 50 may be less taut after outdoor exposure for a period of time than when installed. Also, the barrier 50 may expand after installation in some cases if it is woven or braided. Certain embodiments of the railing system shown in FIGS. 15A and 15B can therefore prevent sagging of the barrier 50 and/or hold it in tension.
FIGS. 15A and 15B show a barrier 50 according to another embodiment. In the embodiment best illustrated in FIGS. 15A and 15B, the barrier 50 includes one or more springs 150 proximal to the stopper 60. In some cases, the springs 150 can be compression springs. Springs 150 can be sized so that each spring 150 is captured between a stopper 60 and a sleeve 70. For example, the spring 150 can be sufficiently small such that it does not slide past the stopper 60 and can be sufficiently large such that it does not slide out of sleeve 70 (e.g., side 160 facing away from the stopper 60). The spring 150 can be provided in one or both first and second ends 52, 54 of the pre-cut barrier 50. The spring 150 facilitates keeping the barrier 50 taut and in tension when the first and second ends 52, 54 of the barrier 50 are connected to corresponding opposite surfaces of railings (e.g., existing railings 110 and 120, or railings 130, 140 of fence 100 shown in FIG. 2). If during use, the barriers 50 have any extra slack that would cause them to sag instead of extending linearly between railings (e.g., existing railings 110 and 120, or railings 130, 140 of fence 100), the spring 150 develops a spring force to pull the barrier 50 until linear and/or taut.
With continued reference to FIGS. 15A and 15B, the spring force “F” generated by each compression spring 150 can be generally oriented along a longitudinal axis 160 of each barrier 50. The spring force “F” generated by each compression spring is directed generally toward the first and second strip (20, 30 best seen in FIG. 7) or away from the center 170 of the barrier 50 as illustrated by arrows “d” and “e” such that the barrier is held in tension. The spring force “F” may act to pull portions of the barrier 50 that sag centrally, thereby having the barrier extend substantially linearly between the first and second strips when held in tension.
Certain embodiments may include a method of mounting a railing system 10 to railings of a fence 100. The method can involve the step of providing a railing system 10 such as those described herein. A desired number of anchors 40 can be positioned on the openings 36 of the first and second strips 20, 30 such that the leading edge 42 and shank 44 of each anchor 40 extends in a direction from the second surface 34 to the first surface 32. When positioned, the flared portion 46 of each anchor 40 is prevented from passing through the respective opening so that the flared portion 46 anchors the anchor 40 against the second surface 34 of the one of the first and second strips 20, 30. Once the anchors 40 are positioned in the openings 36, the first and second strips 20, 30 can be mounted to respective railings 110, 120 of the fence 100 such that each second surface 34 faces and engages a respective railing of a fence (e.g., as shown in FIG. 5A). Once mounted, the flared portions 46 of each anchor 40 being are captured between first or second strip 30 and the respective railing 110, 120. In some embodiments, the mounting fixes the flared portion 46 of each anchor 40 against the respective fence railing 110, 120. As shown in FIG. 5B, and described herein, the first and second strips 20, 30 are mounted to respective railings 110, 120 by fasteners 38, or bonded therewith (e.g., by adhesives).
The shank 44 of each anchor 40 can then be bent with respect to its flared portion 46 to a desired angle to have the desired angular orientation. In some embodiments, the angle between the bent shank 44 and the flared portion 46 is between about 1 degree and about 85 degrees. In some embodiments, the method of mounting the railing system 10 to the railings 110, 120 of a fence 100 includes connecting a bending tool 80 as described herein (e.g., as shown in FIG. 10) to the leading edge 42 of one of the anchors 40, grasping and manipulating the bending tool 80 to bend the shank 44 of the one of the anchors 40 with respect to its flared portion 46, and disconnecting the bending tool 80 from the leading edge 42 of the one of the anchors 40. Once the anchor 40 is bent to a desired angle, the first and second ends 52, 54 of each elongated barrier 50 can be connected to one of the anchors 40 (e.g., via a threaded engagement by applying a torque with a tool such as a wrench 90, as shown in FIG. 14) so that each barrier 50 extends linearly from the first strip 20 to the second strip 30.
Thus, embodiments of railing system are disclosed. The disclosed embodiments are presented for purposes of illustration and not limitation and other embodiments are possible. One skilled in the art will appreciate that various changes, adaptations, and modifications may be made without departing from the spirit of the invention.
