## Background
TECHNICAL FIELD
The present invention relates generally to gates, and more particularly to gates for swimming pool fences.
BACKGROUND OF THE INVENTION
Unsecured pools present a drowning hazard to unattended children. Accordingly, pools are commonly provided with a fence surrounding the pool to prevent children from inadvertently falling into the pool. Additionally, the fence surrounding the pool is commonly provided with a gate to allow convenient access to and from the pool. Moreover, such gates are commonly provided with locks to prevent children from opening the gate. Conventional gates also may be provided with structural members not present on the remainder of the fence because the gate is subject to additional loading due to the repeated opening and closing of the gate. These additional structural members on conventional gates, however, may be configured such that children can climb over the gate and thereby access the pool. For instance, conventional gates may include structural features, such as rods, poles, or stringers, which permit children to scale the gate and thereby access the pool.
Additionally, conventional pool fences and gates are typically shipped in a fully or partially assembled state in order to ensure the structural integrity and rigidity of the fence and gate upon installation around the pool. Gates, in particular, are typically shipped in an assembled state. However, shipping fences and gates in a partially or fully assembled state requires a large shipping container, which adds significant delivery expense to the fence and gate and limits the type of vehicles which are capable of transporting the fence and gate. An assembled gate will have a width and height that will take considerable clearance for packing and shipping.
As such, there is a need for a fence and gate which are configured to prevent children from climbing the gate and which are configured to be transported in a compact disassembled state and then assembled in situ into a structurally rigid frame around the pool.

DETAILED DESCRIPTION
The present invention is directed to a fence and a gate. The drawings depict the invention as applied to swimming pools for illustrative purposes only, and it is appreciated that the present invention may be used in other applications, such as to restrict access to playground structures (e.g., trampolines), buildings, and other private property (e.g., backyards). The gate and fence of the present invention are configured to prevent children from climbing the gate and thereby accessing the structure or property to which access is limited. Additionally, the gate and fence of the present invention are configured to be shipped in a compact disassembled state and then assembled in situ around the desired structure or property.
With reference now to the embodiment illustrated in FIG. 1, the fence 100 and gate 101 of the present invention are shown installed around the perimeter of a pool 102 having a pool decking 103 adjacent the pool 102. The fence 100 includes a plurality of spaced apart vertical fence posts 104. In the illustrated embodiment, lower ends of the vertical fence posts 104 extend into apertures 105 (e.g., cylindrical bores) in the pool decking 103 or other structure surrounding the pool 102. The vertical fence posts 104 may have any suitable shape, such as thin-walled cylindrical tubes, cylindrical rods, square bars, or flat plates. The vertical fence posts 104 may be made of any suitably strong material, such as aluminum, steel, fiberglass, or carbon fiber reinforced plastic. The fence posts 104 may be formed from any suitable process, such as machining, extruding, molding, or rapid prototyping using additive manufacturing.
With continued reference to FIG. 1, the fence 100 also includes a mesh screen 106 tensioned between the vertical fence posts 104. In one embodiment, the screen 106 may be installed with approximately 15-20 lbs of tension between the vertical fence posts 104. Additionally, the vertical fence posts 104 and the apertures 105 in the pool decking 103 may be canted (e.g., approximately 5 degrees) to compensate for the tension loading on the vertical fence posts 104 supplied by the tensioned screen 106. The screen 106 may be secured to the vertical fence posts 104 by any suitable means, such as bonding, adhering, or fastening.
The screen 106 includes a plurality of interconnected longitudinal strands 107 and transverse strands 108 arranged in a grid-like pattern. The strands 107, 108 may be interconnected by any suitable means, such as interlacing, bonding, adhering, or knotting. Together, the longitudinal and transverse strands 107, 108 define a grid of rectangular openings 109 in the fence 100. In one embodiment, the openings 109 are sized to prevent a child's fingers and toes from extending through the screen 106 (e.g., approximately 0.25 square inches), thereby inhibiting a child from climbing the fence 100. It will be appreciated, however, that the present invention is not limited to the size of the openings 109 recited above, and openings 109 of any suitable size are within the scope and spirit of the present invention. The screen 106 may be made of any suitable strong and durable material, such as aluminum, nylon, or vinyl-coated metal. A suitable fence 100 structure is described in U.S. Pat. No. 5,664,769, assigned to the applicant of the present invention, the entire contents of which are hereby incorporated by reference.
With continued reference to FIG. 1, the fence 100 also includes at least one access opening 110 defined between two adjacent vertical fence posts 104′, 104′′. Gates 101 are provided in each of the access openings 110 in the fence 100 to provide ingress to and egress from the pool or other structure to which the fence 100 restricts access. One side of the gate 101 is hingedly coupled to one of the fence posts 104′ defining the access opening 110 such that the gate 101 is configured to move between an open position and a closed position. In one embodiment, the gate 101 may be hingedly coupled to the fence 100 by two spring-loaded hinges, as shown and described in U.S. Pat. No. 5,664,769. The gate 101 and fence 100 may also include a mechanism configured to releasably lock the gate 101 in the closed position, such as a latch and catch, a hook and eye latch, or the magnetic latch shown and described in U.S. Pat. No. 5,664,769. The locking mechanism may be coupled the other fence post 104′′ defining the access opening 110 and the side of the gate 101 opposite the hinged side of the gate 101.
With reference now to the embodiment illustrated in FIGS. 2A, 2B, and 3, the gate 101 includes two spaced apart vertical support posts 111, 112 and a lower horizontal post 113 extending between the vertical posts 111, 112. Together, the vertical support posts 111, 112 and the lower horizontal support 113 define a generally U-shaped frame. In the illustrated embodiment of FIG. 6, the vertical support posts 111, 112 are thin-walled tubes having an outer diameter and an inner diameter d. The inner diameter d of the vertical support posts 111, 112 is defined by a smooth bore 114 extending the entire length of the vertical support posts 111, 112. Upper and lower ends 115, 116 of the vertical support posts 111, 112 include openings 117, 118 (e.g., cylindrical holes), respectively, extending into the bores 114, the significance of which is explained below. Similarly, in the illustrated embodiment of FIG. 7, the lower horizontal support 113 is a thin-walled tube having an outer diameter and an inner diameter. The inner diameter of the lower horizontal support 113 is defined by a smooth bore 120 extending the entire length of the lower horizontal support 113. Opposite ends 121, 122 of the lower horizontal support 113 include openings 119, 123 (e.g., cylindrical holes) extending into the bore 120, the significance of which is explained below. Although the supports 111, 112, 113 are illustrated as tubular members, the supports 111, 112, 113 may have any other suitable shape, such as square bar, flat plate, or cylindrical rod. The supports 111, 112, 113 may be made of any suitably strong material, such as aluminum, steel, fiberglass, or carbon fiber reinforced plastic. The supports 111, 112, 113 may be formed by any suitable process, such as machining, extruding, molding, or rapid prototyping using additive manufacturing.

In an alternate embodiment, the outer diameter of the annular lips 170, 171 on the vertical legs 162 of the Tees 160, 161 are substantially equal to the inner diameter of the bores 154, 114 in the upper posts 150, 151 and the vertical support posts 111, 112 such that the Tees 160, 161 are configured to be secured to the upper posts 150, 151 and the vertical support posts 111, 112 with press fit connections (i.e., interference fit). In the illustrated embodiment of FIG. 2B, the outer diameter of the tubular body portion 168 of the vertical leg 162 of the Tees 160, 161 is substantially equal to the outer diameter of the upper posts 150, 151 and the vertical support posts 111, 112 such that the Tees 160, 161 are flush with the upper posts 150, 151 and the vertical support posts 111, 112 when the Tees 160, 161 are attached to the upper posts 150, 151 and the vertical support posts 111, 112.
With continued reference to FIGS. 2B and 3, the horizontal legs 165 of the Tees 160, 161 are configured to support a cross-brace 180, described in detail below, extending horizontally between the upper post 150 and the vertical support post 111 on one end and the upper post 151 and the vertical support post 112 on the other end. In the illustrated embodiment of FIG. 5, the free ends 167 of the horizontal legs 165 of the Tees 160, 161 include thin-walled annular lips 181 having an outer diameter and an inner diameter. The inner diameters of the annular lips 181 are defined by smooth bores 182 extending along at least a portion of the horizontal leg 165. The outer diameter of the annular lips 181 is smaller than the outer diameter of the tubular body portion 169 of the horizontal leg 165 such that shoulders 183 are defined between the annular lips 181 and the tubular body portion 169 of the horizontal leg 165.
The Tees 160, 161 may also include narrow channels or grooves 184 configured to increase the structural rigidity of the Tees 160, 161. In the illustrated embodiment of FIGS. 2B, 3, and 5, the narrow channels 184 extend along the tubular body portions 168, 169 of the Tees 160, 161. It will be appreciated, however, that the Tees 160, 161 may be provided without the narrow channels 184 and still fall within the scope and spirit of the present invention. The Tees 160, 161 may be made of any suitably strong material, such as fiberglass, fiberglass reinforced nylon, aluminum, carbon fiber reinforced plastic, or steel. The Tees 160, 161 may be made from any suitable process, such as machining, molding, welding, stamping, or rapid prototyping using additive manufacturing.
With reference now to the embodiment illustrated in FIGS. 2A and 2B, the gate 101 also includes a rectangular gate screen 190 having opposing sides 191, 192 and opposing upper and lower ends 193, 194. The gate screen 190 is tensioned between the vertical support post 111 and the upper post 150 on one side 191 and the vertical post 112 and the upper post 151 on the other side 192. Additionally, the lower end 194 of the gate screen 190 is coupled to the lower horizontal support 113. The gate screen 190 includes a plurality of interconnected longitudinal strands 195 and transverse strands 196 disposed in a grid-like pattern, substantially as described above. The strands 195, 196 may be interconnected by any suitable means, such as interlacing, bonding, adhering, or knotting. Together, the longitudinal and transverse strands 195, 196 define a grid of rectangular openings 197 in the gate 101. In one embodiment, the openings 197 are sized to prevent a child's fingers and toes from extending through the gate screen 190 (e.g., approximately 0.25 square inches), thereby inhibiting a child from climbing the gate 101. It will be appreciated, however, that the present invention is not limited to the size of the openings 197 recited above, and openings 197 of any suitable size are within the scope and spirit of the present invention. Additionally, it will be appreciated that the free upper end 193 of the gate screen 190 is flexible and is therefore configured to prevent an individual from climbing over the gate 101. The gate screen 190 may be made of any sufficiently suitable strong and durable material, such as aluminum, nylon, or vinyl-coated metal.
With continued reference to FIGS. 2A and 2B, the gate screen 190 includes edge bindings 198 extending along the sides 191, 192 and ends 193, 194 of the gate screen 190 (i.e., the edge bindings 198 extend around the periphery of the gate screen 190). In one embodiment, the edge bindings 198 are made of a fabric material, such as nylon, acrylic, linen, or cotton. The edge bindings 198 may be attached to the gate screen 190 by any suitable means, such as bonding, adhering, or mechanical fastening (e.g., stitching). The edge bindings 198 are configured to prevent the strands 195, 196 of the gate screen 190 from fraying, which might otherwise prematurely wear down the gate screen 190. Additionally, fasteners 199 securing the gate screen 190 to the vertical and horizontal posts 111, 112, 113 are configured to engage the edge bindings 198. The edge bindings 198 may have any suitable width, such as between approximately 0.25 inch and 2 inches, depending upon various factors, such as the outer diameter of the posts 111, 112, 113 and the size of the gate screen 190. It will be appreciated, however, that the gate screen 190 may be provided without the edge bindings 198 and still fall within the scope and spirit of the present invention.
With reference now to the embodiment illustrated in FIGS. 2A, 3, 10A, and 10B, the gate 101 also includes three tensioning plates 200, 201, 202 configured to secure the gate screen 190 to the vertical support posts 111, 112 and the lower horizontal support 113.

Together, the flat plate 203 and the teeth 204, 205 have a generally U-shaped transverse cross-section. The first and second tensioning plates 200, 201 have substantially the same length of the sides 191, 192 of the gate screen 190, as illustrated in FIG. 2A. The third tensioning plate 202 is substantially the same length as the lower end 194 of the gate screen 190. The tensioning plates 200, 201, 202 also include a plurality of openings 206 configured to receive the fasteners 199 securing the tensioning plates 200, 201, 202 to the gate screen 190 and the posts 111, 112, 113. When the gate screen 190 and the tensioning plates 200, 201, 202 are installed, the sides 191, 192 of the gate screen 190 are disposed between the tensioning plates 200, 201 and the vertical support posts 111, 112, respectively, and the lower end 194 of the gate screen 190 is disposed between the tensioning plate 202 and the lower horizontal support 113, as illustrated in FIG. 2A. The plurality of fasteners 199 extend through the tensioning plates 200, 201, 202, the edge bindings 198 of the gate screen 190, and the supports 111, 112, 113 to secure the gate screen 190 to the supports 111, 112, 113. When the gate screen 190 and the tensioning plates 200, 201, 202 are installed, the fasteners 199 draw the teeth 204, 205 on the tensioning plates 200, 201, 202 into engagement with the edge bindings 198 of the gate screen 190. Moreover, when the fasteners 199 are installed, head portions of the fasteners 199 abut the flat rectangular bases 203 of the tensioning plates 200, 201, 202. The tensioning plates 200, 201, 202 may be made of any suitably strong material, such as aluminum, steel, fiberglass, or carbon fiber reinforced plastic. The tensioning plates 200, 201, 202 may be formed by any suitable process, such as machining, extruding, molding, stamping, welding, or rapid prototyping using additive manufacturing.
With reference now to the embodiments illustrated in FIGS. 2B and 3, the gate 101 includes a cross-brace 180 configured to add rigidity to the gate 101. The cross-brace 180 on the gate 101 extends between the horizontal legs 165 of the two Tees 160, 161. The cross-brace 180 is disposed on the inner pool-facing side of the gate 101 such that the cross-brace 180 does not present a handgrip or foothold for children to climb over the gate 101 from the outside of the gate 101 (i.e., the cross-brace 180 is disposed between the gate screen 190 and the pool 102 or other structure to which the gate 101 and fence 100 restrict access, as illustrated in FIG. 1). Additionally, the cross-brace 180 is sufficiently spaced below the upper edge 193 of the gate screen 190 such that a child cannot reach over the gate screen 190 from the outside of the gate 101 and grab onto the cross-brace 180, thereby inhibiting children from climbing over the gate 101. In one embodiment, the cross-brace 180 is spaced between approximately 4 inches and approximately 8 inches below the upper edge 193 of the gate screen 190. It will be appreciated, however, that the present invention is not limited to the spacing between the cross-brace 180 and the upper edge 193 of the gate screen 190 recited above, and any suitable spacing may be selected based upon the overall height of the gate 101 and the height of the children to whom the fence 100 and gate 101 are configured to restrict access to the pool 102. In an alternate embodiment, the cross-brace 180 may be aligned with the upper edge 193 of the gate screen 190.

In one embodiment, the middle portion of the cross-brace 180 extends between approximately 1 inch and approximately 3 inches rearwardly away from the gate screen 190. It will be appreciated, however, that the present invention is not limited to the spacing between the cross-brace 180 and the gate screen 190 recited above, and any suitable spacing may be selected based upon the overall height of the gate 101 and the height of the children to whom the fence 100 and gate 101 are configured to restrict access to the pool 102. In an alternate embodiment, the cross-brace 180 may be in direct contact with the gate screen 190.
In the illustrated embodiment of FIG. 8, the cross-brace 180 is a thin-walled tube having an outer diameter and an inner diameter. The inner diameter of the cross-brace 180 is defined by a smooth bore 210 extending the entire length of the cross-brace 180. The cross-brace 180 may be formed by any suitable means, such as machining, molding, welding, stamping, roll forming, or rapid prototyping using additive manufacturing. Although the cross-brace 180 is illustrated as a thin-walled cylindrical tube, the cross-brace 180 may have any other suitable shape, such as a rod, a square bar, or a plate.
The horizontal legs 165 of the Tees 160, 161 are configured to couple opposite ends 211, 212 of the cross-brace 180 to the gate 101. In one embodiment, the outer diameters of the annular lips 181 on the horizontal legs 165 of the Tees 160, 161 are slightly smaller than the inner diameter of the cross-brace 180 such that the annular lips 181 are configured to be inserted into the opposite ends 211, 212 of the smooth bore 210 in the cross-brace 180, as illustrated in FIG. 2B. When the annular lips 181 are inserted into the bore 210 in the cross-brace 180, the shoulders 183 on the Tees 160, 161 are configured to abut the opposite ends 211, 212 of the cross-brace 180.
The Tees 160, 161 may be coupled to the cross-brace 180 by any suitable means, such as fasteners (e.g., hex head screws), adhesive, bonding, welding, or brazing. In the illustrated embodiment of FIG. 5, the annular lip 181 on the horizontal leg 165 of each Tee 160, 161 includes an opening 213 (e.g., cylindrical holes).

Additionally, in the illustrated embodiment of FIG. 11, the outer diameter of the tubular body portion 410 of the horizontal leg 406 of each Tee 401, 402 is substantially equal to the outer diameter of the cross-brace 417 such that the Tees 401, 402 are flush with the cross-brace 417 when the Tees 401, 402 are attached to the cross-brace 417.
With continued reference to the embodiment illustrated in FIGS. 12A and 12B, the Tees 401, 402 each also include upper and lower gussets 420, 421, respectively, configured to increase the rigidity and load-bearing capacity of the Tees 401, 402. In the illustrated embodiment, the upper gusset 420 is a generally triangular, curved plate extending between the upper shoulder 415 of the vertical leg 403 and the shoulder 419 of the horizontal leg 406. Similarly, the lower gusset 421 is a generally triangular, curved plate extending between the lower shoulder 416 of the vertical leg 403 and the shoulder 419 of the horizontal leg 406. It will be appreciated, however, that the gussets 420, 421 may have other suitable configurations and still fall within the scope and spirit of present invention. For instance, the gussets 420, 421 may not extend completely to the shoulders 415, 416, 419 of the vertical and horizontal legs 403, 406.
With continued reference to the embodiment illustrated in FIGS. 12A and 12B, the Tees 401, 402 also include a series of narrow horizontal channels or grooves 422 configured to increase the structural rigidity of the Tees 401, 402. In the illustrated embodiment, the narrow channels 422 extend along the tubular body portions 409, 410 of the Tees 401, 402. In another embodiment, the narrow channels 422 may extend along both the tubular body portions 409, 410 and the gussets 420, 421 of the Tees 401, 402. Additionally, it will be appreciated that the Tees 401, 402 may be provided without the narrow channels 422 and still fall within the scope and spirit of the present invention.
With reference now to FIG. 13, a Tee connector 425 according to another embodiment of the present invention is illustrated. The Tee connector 425 includes a vertical leg 426 and a horizontal leg 427, substantially as described above with reference to FIGS. 12A and 12B. However, the upper and lower ends of the vertical leg 426 and the free end of the horizontal leg 427 include generally rectangular lips 428, 429, 430, respectively, rather than the circular lips 411, 412, 418 illustrated in FIGS. 12A and 12B. The rectangular lips 428, 429, 430 each include two spaced apart straight segments 431, 432 and two arcuate segments 433, 434 connecting opposite ends of the straight segments 431, 432. The rectangular lips 428, 429 on the vertical leg 426 are configured to be received in generally rectangular openings 435 in the upper ends 115 of the vertical support posts 111, 112 and the lower ends 153 of the upper vertical posts 150, 151. Additionally, the rectangular lip 430 on the free end of the horizontal leg 427 is configured to be received in generally rectangular openings in the opposite ends 423, 424 of the cross-brace 417. Moreover, in one embodiment, the elbow joints also include generally rectangular lips, rather than the circular lips 135, 136 illustrated in FIG. 4, which are configured to be received in generally rectangular openings in the lower ends 116 of the vertical support posts 111, 112 and the opposite ends 121, 122 of the lower horizontal support 113. Each of the generally rectangular openings 435 in the upper vertical posts 150, 151, the vertical support posts 111, 112, the cross brace 417, and the lower horizontal support 113 includes two straight segments 436, 437 and two arcuate segments 438, 439 extending between the ends of the straight segments 436, 437. The straight segments 436, 437 and the two arcuate segments 438, 439 of the generally rectangular openings are configured to match the contour of the straight segments 431, 432 and two arcuate segments 433, 434 of the generally rectangular lips on the Tees 425 and the elbows. The rectangular lips 428, 429, 430 on the Tees 425 and the elbows and the corresponding rectangular openings in the upper vertical posts 150, 151, the vertical support posts 111, 112, the cross-brace 417, and the lower horizontal support 113 are configured to prevent the support members 150, 151, 111, 112, 417, and 113 from rotating relative to the Tees 425 and the elbows. Otherwise, such rotation may cause the gate to flex and become misaligned.
Although the Tees and elbows have been describe above with reference to generally rectangular lips having two straight segments, the Tees and elbows may alternately be provided with only one straight segment (i.e., each of the lips on the ends of the Tees and elbows may include an arcuate segment and a single straight segment). Similarly, although the upper vertical posts, the vertical support posts, the cross-brace, and the lower horizontal support have been described above with reference to generally rectangular openings having two straight segments, each of the openings may alternately be provided with only one straight segment. In one embodiment, when the gate is assembled, the single straight segment in each of the openings aligns with the single straight segment on each of the lips on the Tees and elbows in order to prevent the upper vertical posts, the vertical support posts, the cross-brace, and the lower horizontal support from rotating relative to the Tees and elbows.
The rectangular lips 428, 429, 430 may have any suitable length, depending upon the desired connection strength and rigidity between the Tees and elbows and the upper vertical posts, the vertical support posts, and the cross-brace. The rectangular lips 428, 429, 430 may be relatively longer as illustrated in FIG. 13 or relatively shorter as illustrated in FIGS. 12A and 12B with reference to the circular lips 411, 412, 418. It will be appreciated that relatively longer lips on the Tees and elbows are configured to provide a more rigid connection between the Tees and elbows and the upper vertical posts, the vertical support posts, and the cross-brace.
The Tees 160, 161 (or 401, 402 or 425) may be made of any suitably strong material, such as fiberglass, fiberglass reinforced nylon, aluminum, carbon fiber reinforced plastic, or steel. The Tees 160, 161 (or 401, 402 or 425) may be made from any suitable process, such as machining, molding, welding, stamping, or rapid prototyping using additive manufacturing.
