Flexible mesh component for amusement park equipment

Abstract

Embodiments of an amusement park device (800, 1700) that includes a mesh lattice frame (100, 200, 300, 400, 502, 802, 1702) are disclosed. The mesh lattice frame (100, 200, 300, 400, 502, 802, 1702) is attached directly or indirectly to the amusement park device (800, 1700). A first segment (412) and a second segment (414) of the mesh cord (102, 202, 302, 402, 1000, 1100) are part of the mesh lattice frame (100, 200, 300, 400, 502, 802, 1702) and include a woven outer mesh cord layer (1102) surrounding a woven inner mesh cord layer (1106). The mesh clamp (104, 204, 304, 404, 1600) is also part of the mesh lattice frame (100, 200, 300, 400, 502, 802, 1702). The first section (412) and the second section (414) of the mesh cord (102, 202, 302, 402, 1000, 1100) extend substantially parallel to each other through the mesh clip (104, 204, 304, 404, 1600). A web clamp (104, 204, 304, 404, 1600) secures the first segment of the web cord to the second segment of the web cord at a point where the first segment of the web cord and the second segment of the web cord extend substantially parallel to each other.

Description

Background Art

[0001] The design of components for incorporation into playground equipment presents unique challenges. Consideration should be given to the fact that playground equipment is prone to deferred maintenance, sometimes years passing between parts replacements. Optimization to avoid injuries from falls and the like should also be considered. Playground equipment components should be designed to withstand extreme environmental considerations—winter is often snow and ice, followed by extreme heat and precipitation in the spring / summer. Consideration should also be given to the fact that playground equipment components are often used by children with little or no supervision. Finally, many, if not most, playground equipment components are exposed to the elements with little or no monitoring, making them vulnerable to vandalism. With these and other factors in mind, it takes great designers to create desirable playground equipment components. There is a constant need for well-designed components that playground equipment designers can confidently select from. Summary of the invention

[0002] Embodiments of playground equipment including a mesh lattice frame are disclosed. The mesh lattice frame is directly or indirectly attached to the playground equipment. A first section and a second section of mesh rope are part of the mesh lattice frame and include a braided outer mesh rope layer surrounding a braided inner mesh rope layer. A mesh clamp is also part of the mesh lattice frame. The first section and the second section of mesh rope extend substantially parallel to each other through the mesh clamp. The mesh clamp secures the first section of mesh rope to the second section of mesh rope at a point where the first section of mesh rope and the second section of mesh rope extend substantially parallel to each other.

[0003] These and various other features and advantages that characterize the claimed embodiments will become apparent upon reading the following detailed description and reviewing the associated drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] As playground equipment becomes more versatile and recreational, mesh-type components are becoming more common. For many playground equipment, it is desirable that mesh-type components comfortably accommodate multiple users of various body types. For many playground equipment, it is also desirable that mesh-type components exhibit long-term strength and durability. The embodiments described herein address these and other design considerations for mesh-type playground equipment components.

[0020] Figure 1 1 is a perspective view of a portion of a mesh lattice framework 100. The mesh lattice framework 100 illustratively includes one or more mesh ropes 102 that are at least substantially evenly distributed to form the mesh lattice framework 100. The mesh rope 102 may include a plurality of individual mesh rope segments, such as segments of the same or different lengths. Alternatively, it may be a continuous mesh rope 102 of sufficient length to form some or all of the mesh lattice framework 100.

[0021] The mesh lattice framework 100 also illustratively includes a plurality of mesh clamps 104. As shown, the network of mesh clamps 104 is at least substantially uniformly arranged. Figure 1 As shown, the group of mesh clamps 104 form a line in the horizontal direction ( Figure 1 The mesh clamps 104 are then grouped to form a line in the vertical direction ( Figure 1 104). Each mesh clamp 104 pulls two portions of the mesh rope 102 toward each other to form a visually appealing pattern inherent to the mesh lattice frame 100. As described in further detail below, in one embodiment, the mesh clamps 104 are configured to secure adjacent portions of the mesh rope 102 (which may or may not be in contact depending on the mesh clamp 104 design) via a crimp-type engagement between the mesh clamps 104 and the portions of the mesh rope 102. However, it is expressly contemplated that other means of securing portions of the mesh rope 102 together (e.g., welding) may be utilized.

[0022] like Figure 1 As shown, the positioning of the mesh clamps 104 relative to each other determines the size, shape, and distribution of the spaces incorporated into the pattern of the mesh lattice framework 100. Figure 1 In the embodiment of the present invention, an example of a single space formed in the mesh lattice frame 100 is indicated by reference numeral 106. However, since the mesh fixtures 104 are substantially evenly distributed into aligned columns and rows of mesh fixtures 104, the space 106 is repeated throughout the body of the mesh lattice frame 100. The space 106 formed in the lattice frame 100 can be illustratively modified by changing the relative positioning of the mesh fixtures 104. For example, by spacing the mesh fixtures 104 of successive columns or rows closer together, the size of the adjacent mesh spacing 106 will be reduced. Of course, it logically follows that spacing the mesh fixtures 104 of successive columns or rows farther apart will increase the size of the adjacent mesh spacing 106. Further, the mesh fixtures 104 do not need to be uniformly aligned into columns or rows. The distribution of the mesh fixtures can be organized in an infinite combination to produce uniform or even non-uniform spacing 106 throughout the mesh lattice frame 100. In other examples, the mesh clamps 104 are not uniformly spaced at one or more locations, thereby varying in size, shape, and / or configuration from one spacing 106 to the next. For example, the spacing 106 on the mesh lattice framework 100 can be easily varied in a uniform or non-uniformly organized manner, depending on the requirements of a given application.

[0023] The mesh clamp 104 is fixed to the part of the mesh rope 102 so that the elongated centerline axis of the mesh rope 102 is permanently fixed in a common plane--in each mesh clamp 104. However, the mesh clamps 104 adjacent to each other in a common column or row are allowed to move freely relative to each other. Like this, the mesh lattice frame 100 is naturally flexible. Considering the described scheme that the parts of the mesh rope 102 are connected together, the mesh lattice frame 100 is configured as a whole to respond to adapt to the applied weight or pressure by complying. In an embodiment that will be described in more detail about other accompanying drawings, the mesh rope 102 also adopts a firm but flexible design structure, which makes the mesh lattice frame 100 recover some or all of its original shape and configuration after weight or pressure are reduced. For example, if a user sits on the mesh lattice frame 100, the mesh lattice frame 100 can comfortably fit the user's body. When the user leaves the mesh lattice frame 100, it will illustratively automatically resume some or all of the shape and configuration that the user had before sitting down. Thus, the mesh lattice frame 100 has both a solid device for easy climbing and a resiliency for comfortable resting, while also maintaining the pleasing aesthetic features of the lattice frame.

[0024] Figure 2 is a perspective view of a portion of a mesh lattice frame 200. The mesh lattice frame 200 includes Figure 1 The mesh lattice frame 100 is similar to that of Figure 2 202. Similar parts will be numbered similarly. One or more mesh ropes 202 are exemplarily connected together at different positions using mesh clamps 204 to form mesh lattice framework 200. The mesh lattice framework 200 then further includes a boundary rope 206 arranged along the outer periphery of the mesh lattice framework 200 to provide support and maintain tension. The boundary rope 206 exemplarily has a larger diameter relative to one or more mesh ropes 202. The boundary rope 206 is configured to support the looped portion of the mesh rope 202. Like this, the boundary rope 206 provides a termination point or transition point 208 for one or more parts of the mesh rope 202. The termination point or transition point 208 can include any number of loops around the boundary rope 206. However, for many applications, a low number of loops (such as 1 to 3) will provide suitable structural integrity without the need to unnecessarily increase additional material costs.

[0025] Also like Figure 2As shown, in one embodiment, a transition loop 210 is provided in one or more mesh ropes 202 to further facilitate anchoring or transition at the boundary rope 206. In one embodiment, the free distal end of one or more mesh ropes 202 is fixed at or near the termination point or transition point 208. However, in another embodiment, the mesh rope 202 is anchored and transitioned at point 208 without including any free ends, but rather the mesh rope 202 transitions (loops) around the boundary rope 206 one or more times (including or not including the transition loop 210) before returning to the mesh lattice framework 200 as the next adjacent segment of the mesh rope 202. In this way, the entire lattice framework 200 (excluding the boundary ropes 206, etc.) can be composed of a single segment of mesh rope 202. In addition, as Figure 2 As shown, any portion of the transition loop 210 and / or the mesh rope 202 may be further secured and / or oriented using one or more additional mesh clamps 204A. In this way, unraveling of the terminal or transition portion of the mesh rope 202 at the boundary rope 206 is mechanically prevented.

[0026] Figure 3 is a perspective view of a portion of a mesh lattice frame 300. The mesh lattice frame 300 includes similarities to the previously described mesh lattice frames 100 and 200, and Figure 3 Like parts in the drawings will be numbered likewise. The mesh lattice frame 300 is particularly similar to Figure 2 300. The mesh lattice framework 300 includes one or more mesh ropes 302 and one or more mesh fixtures 304 configured to be coupled together to form the structure and pattern of the mesh lattice framework 300. The mesh lattice framework 300 further includes a boundary rope 306. The portion of the mesh rope 302 has been routed to form a plurality of rope loops 310 (only a representative one is marked), wherein the rope loop 310 is adjacent to the portion of the mesh rope 302 around the boundary rope 306 loop position to form, thereby forming several terminals or transition portions at the termination point or transition point 308. For example, the rope loop 310 of the mark exemplarily terminates or transitions twice around the boundary rope 306, and is fixed in place by a plurality of additional mesh fixtures 304A, as shown. However, in other examples, more or less loops around the boundary rope 306 can be utilized. In this manner, unraveling of the terminal or transitional portion of the mesh rope 302 around the boundary rope 306 is mechanically inhibited.

[0027] One difference of the mesh lattice frame 300 is the inclusion of a rope hook 312 to facilitate securing the boundary rope 306 to the playground equipment 314. The rope hook 312 is illustratively configured to support the boundary rope 306 within the hook portion of the rope hook 312. By supporting the boundary rope 306, the rope hook 312 helps maintain tension on the mesh lattice frame 300. In one example, the rope hook 312 can be compressed or crimped around the boundary rope 306. In other examples (such as those described below in conjunction with other figures), the boundary rope 306 is securely locked in the rope hook 312 by firmly pressing the boundary rope 306 into the hook portion of the rope hook 312 and then using a hook cover ( Figure 3 (not shown) fixing the boundary rope 306.

[0028] In one embodiment, the rope hooks 312 are coupled to the equipment 314 by welding. However, it is expressly contemplated that other means of coupling the rope hooks 312 to the equipment 314 may be utilized. By including one or more rope hooks 312, the boundary ropes 306, and therefore the mesh lattice frame 300, may be secured and coupled to most any playground equipment. Those skilled in the art will recognize that in addition to rope hooks, there are other suitable ways to couple the mesh lattice frame embodiments described herein to playground equipment, such as, but not limited to, clamping or by including eyebolts or other similar connectors that may or may not require welding.

[0029] Figure 4 is a perspective view of a portion of a mesh lattice frame 400. The mesh lattice frame 400 includes similarities to the previously described mesh lattice frames 100, 200, and 300, and Figure 4 Like parts in the drawings will be numbered likewise. The mesh lattice frame 400 is particularly similar to Figure 2 4. The mesh lattice frame 400 includes one or more mesh ropes 402 and one or more mesh clamps 404 configured to form the structure and pattern of the mesh lattice frame 400. Boundary ropes 406 illustratively support the outer perimeter of the mesh lattice frame 400. Boundary ropes 406 support one or more mesh ropes 402. In one embodiment, the mesh clamps 404 are positioned and configured to guide the mesh ropes 402 to close engagement with the boundary ropes 406, which limits or prohibits friction or other abrasive effects between the mesh ropes 402 and the boundary ropes 406. In this way, the shape of the opening in the mesh lattice frame 400 may be consistent or inconsistent with the shape of the opening away from the boundary ropes 406.

[0030] In one embodiment, Figure 4As shown, the mesh rope 402 does not have an untied end, but terminates or transitions (that is, loops) around the boundary rope 406 once or multiple times, and then continues in the opposite direction to form the adjacent path (run) of the rope 402 in the overall mesh lattice frame 400 structure. For example, in one embodiment, the segment 412 of the mesh rope extends toward the boundary rope 406, and terminates or transitions (that is, loops) around the boundary rope 406 several times (for example, twice), and then travels as another segment 414 in the opposite direction. Segment 412 and segment 414 are clamped together by the mesh clamp 404 (according to the mesh clamp 404 design, these segments can contact or not contact each other). This routing of the mesh rope 402 towards and away from the boundary rope 406 plus the clamping of the mesh clamp 404 produces the shape of the mesh lattice frame 400, as shown in the figure. In summary, it is also envisioned that the single part of the mesh rope 402 can be used to replace the continuous rope 402 design shown.

[0031] In addition, if Figure 4 As shown, the boundary ropes 406 are secured to the playground equipment 410 by a plurality of rope hooks 408. The rope hooks 408 may be secured to the playground equipment 410 by, for example, welding. However, it is expressly contemplated that other means of securing the rope hooks 408 to the equipment 410 may be utilized in alternative arrangements. In operation, the plurality of rope hooks 408 secure the boundary ropes 406 to the playground equipment 410, thereby providing sufficient tension and integrity to the mesh lattice frame 400 as a component of a wider playground facility of which the playground equipment 410 is a part.

[0032] Figure 5 is a perspective view of a playground equipment 500 including a mesh lattice frame 502. The mesh lattice frame 502 is illustratively configured to be in accordance with the embodiment of the present invention. Figures 1 to 4 504. As shown, the mesh lattice frame 502 generally covers the interior space within the equipment frame 504. The boundary rope 510 is configured to provide support within the mesh lattice frame 502 structure and also facilitate coupling with the equipment frame 504. The boundary rope 510 is fixed to the frame 504 using a plurality of rope hooks 512.

[0033] In one embodiment, the frame 504 includes one or more curved portions 506. In another embodiment, straight portions are also included, such as straight portion 508. In either case, the boundary ropes 510 are illustratively configured to have sufficient flexibility to line the perimeter of the curved portions 506 and / or the straight portions 508 while maintaining tension on the mesh lattice frame 502. Those skilled in the art will appreciate that the size, shape, and configuration of the playground equipment and the corresponding mesh lattice frame features may vary depending on the requirements of a given playground facility.

[0034] Figure 6 600. As shown, the rope hook 600 includes a concave portion 602, which is configured to accommodate and support boundary ropes, such as the examples of boundary ropes described above with respect to other figures. The size of the concave portion 602 is exemplarily determined to be sufficient to adapt to any boundary rope that meets the applicable requirements of a given facility. The rope hook 600 further includes a lip portion 604, which is configured to further fix and maintain the boundary rope in the concave portion 602. In addition, in one embodiment, the rope hook 600 includes a smooth portion 606 and a serrated portion 608 disposed in the concave portion 602. The serrated portion 608 is configured to further fix the boundary rope by applying friction, digging force or dragging force to prevent the boundary rope from rotating and / or translating in the concave portion 602. In one embodiment, the rope hook 600 further includes a surface 610, which is configured to be coupled to the desired playground equipment. As shown, surface 610 is usually depicted as flat, so as to allow suitable connection to playground equipment. For example, rope hook 600 can be connected to playground equipment at surface 610 by welding surface 610 to playground equipment. However, in other embodiments, surface 610 can be bent in any suitable manner to allow rope hook 600 to be assembled to playground equipment. In one embodiment, rope hook 600 has a length of about 2.25 inches and a relative thickness of about 0.5 inches. However, it is clearly envisioned that different lengths and thicknesses can also be utilized. In addition, in one embodiment, rope hook 600 includes orifice 612. Orifice 612 is configured to receive one or more fasteners therein. For example, fasteners can be used to fix hook cover to rope hook 600. The fasteners used in orifice 612 can be, for example, bolts, screws or any other fasteners suitable for protruding into orifice 612. In one embodiment, orifice 612 is a threaded orifice suitable for corresponding threaded fasteners.

[0035] Fig. 7A and Figure 7B 700. The hook cover 700 includes an inner portion 702 configured to receive a rope hook therein. The rope hook may be, for example, the one described above with respect to Figure 6The rope hook 600 described. The inner portion 702 includes a first gap 704 and a second gap 706, the first gap 704 is configured to facilitate the engagement of the lip portion of the rope hook with the hook cover 700, and the second gap 706 is configured to facilitate the engagement of the body portion of the rope hook with the hook cover 700. In one embodiment, the hook cover 700 can have a length of about 2.25 inches, a height of about 1 and 13 / 16 inches, and a width of about 1.125 inches. In addition, the hook cover 700 further includes an aperture 708, which is configured to allow fasteners to be inserted therein. When installed, the fasteners exemplarily protrude through the aperture 708 and also pass through the holes set in the rope hook so as to couple the hook cover 700 and the rope hook together. The fasteners utilized can be, for example, bolts, screws, or any other fasteners suitable for protruding through the aperture 708. In one embodiment, the aperture 708 is a threaded aperture. In addition, in one embodiment, the aperture 708 has a diameter of about 0.410 inches. In operation, the hook cover 700 is configured to facilitate accommodating the rope hook and provide a protective barrier to prevent any intentional or accidental damage to the rope hook and / or the boundary rope supported by the rope hook.

[0036] Figure 8 800 includes a mesh lattice frame 802 having a plurality of mesh clamps 804 and one or more boundary ropes 806. The boundary ropes 806 are configured to be inserted into and supported by a plurality of rope hooks 808. As shown, each rope hook 808 includes a hook cover. The hook cover is illustratively similar to the above description of the embodiment of the present invention. FIG. 7A to FIG. 7B The hook cover is consistent with the description. The hook cover shown is used to further secure the boundary rope 806 to the rope hook 808 while preventing tampering. In addition, as shown, the rope hook 808 slightly protrudes from the outside of the hook cover so that it can be connected to the frame 810, such as but not limited to being fixed by welding.

[0037] FIG. 9A to FIG. 9B 900. The assembly 900 includes a rope hook 902 secured to a hook cover 904. As shown, a boundary rope 906 extends through the concave portion of the rope hook 902 and the hook cover 904 so that it is secured in place. The size of the boundary rope 906 and / or the rope hook 902 is exemplarily determined so that when the boundary rope 906 is secured in the concave portion of the rope hook 902, there is little to no clearance for movement.

[0038] FIG. 9A to FIG. 9BAlso shown in the figure is a cross-section of the boundary rope 906. As shown, the boundary rope 906 illustratively includes a rope core 910 and six boundary ropes 920. However, in another example, a different number of edge ropes and / or rope cores can be utilized. In one embodiment, the rope edge is reinforced with steel wire, for example. In addition, in one embodiment, the rope core 910 is a steel core, but can easily be composed of a different material (such as a polypropylene core material). In one embodiment, the material is selected so that it is difficult to tear and / or otherwise damage the boundary rope 906. In one embodiment, the diameter of the boundary rope 906 is about 20 millimeters (mm). The following will be about Fig.11 Additional example configurations of the composition of boundary line 906 are discussed.

[0039] The assembly 900 also includes one or more fasteners 908, which are configured to protrude through the aperture 912 and fasten the hook cover 904 to the rope hook 902. As shown, two fasteners 908 are used, each of which is applied to opposite sides of the rope hook 902 and the hook cover 904. However, in other embodiments, one fastener can be used with the aperture 912. The fastener 908 can be, for example, a threaded fastener. However, in other embodiments, other fasteners, such as non-threaded fasteners, can be used.

[0040] Fig.10 1 is a cross-sectional view of a mesh rope 1000. In one embodiment, the mesh rope 1000 is one or more mesh ropes used to form the mesh lattice frame embodiments described above with respect to other figures. The mesh rope 1000 illustratively includes a plurality of braided rope fibers 1002 surrounding a rope core 1004, the rope core 1004 being arranged at a Fig.10 1004 is difficult to see in the embodiment because it is surrounded by multiple braided strands 1006. In one embodiment, each braided strand 1006 and / or core 1004 is itself a braid of individual strands. However, for the present, it is useful to treat braided strands 1006 and core 1004 as separate elements in themselves for the purpose of this specification.

[0041] As mentioned in the description of the previous figure, one or more mesh ropes 1000 utilize a plurality of mesh fixtures to link together, to form a mesh lattice framework. The outer braid of rope fiber 1002 is used to protect braided strand 1006 and rope core 1004 from damage, and also provides comfortable rest and functional climbing surface for playground component users simultaneously. Further, rope fiber 1002 also isolates playground users from relatively sharper, hotter, colder and otherwise uncomfortable braided strand 1006 and / or rope core 1004 to touch. In one embodiment, rope fiber 1002 is formed by braiding polyester. Yet, in other embodiments, another kind of material can be used to form rope fiber 1002 (for example, polyethylene).

[0042] Braided strand 1006 and core 1004 are configured to further prevent one or more mesh ropes 1000 from being damaged over time. For example, braided strand 1006 and core 1004 have reduced the possibility that one or more mesh ropes 1000 will be completely broken, torn, cut or destroyed by destroyers in some way. In addition, the relative rigidity of braided strand 1006 and core 1004 makes the mesh lattice framework maintain its structural integrity and shape when not being subjected to pressure, and also allows temporary shape change to occur when the mesh lattice framework is subjected to pressure such as lying comfortably on the mesh lattice framework by the user. The relative rigidity of braided strand 1006 and core 1004 is combined with their positioning in the rope clamp of the mesh lattice framework, and a certain degree of shape memory function is produced, wherein the mesh lattice framework can be deformed when being subjected to pressure, but can naturally and automatically partially or completely recover to the shape that is not deformed when not being subjected to pressure.

[0043] Fig.11 1 is a cross-sectional view of a mesh rope 1100, which is exemplary identical in all or most aspects to mesh rope 1000. In other words, in one embodiment, the cross-sectional view is a cross-section of mesh rope 1000. As shown, mesh rope 1100 includes an outer layer 1102, which is composed of (not limited to) 12 individually woven rope fibers (these are referred to as Fig.10 In one embodiment, the rope fibers of the outer layer 1102 are formed of a polyester material. In another example, the rope fibers may include fabric or some other relatively soft material (i.e., relatively soft relative to the harder material around which they are woven).

[0044] The diameter of the mesh rope 1100 is defined by the overall diameter of the outer layer 1102. For example, the diameter is about 6.6 millimeters (mm). However, it is clearly contemplated that the mesh rope 1100 can have a larger or smaller diameter, depending on the requirements of a given facility. Diameters in the range of 5 mm to 18 mm are effective to balance the comfort of lying down and the function of an attractive climbing experience. Diameters less than 12 are particularly effective for shape memory effects, where the mesh lattice frame shape automatically recovers when pressure is removed (e.g., there is a person resting). In one embodiment, the entire mesh rope 1100 is immersed in or coated with a protective material to further reduce the possibility of wear and tear, etc. However, such a coating will be light and unlikely to significantly increase the diameter.

[0045] The mesh rope 1100 also includes an inner layer 1106 including, without limitation, six individually braided strands (in Fig.10Inner layer 1106 may or may not be impregnated or coated with a light protective layer. Inner layer 1106 provides damage and tamper resistance. In one embodiment, the lay length of the braided strands in this layer is about 23 mm. However, it is expressly contemplated that different lay lengths may be selected according to the requirements of a given application.

[0046] Finally, the mesh rope 1100 further includes a rope core 1104 disposed within the outer layer 1102 and the inner layer 1106 (in Fig.10 1004). The diameter of the core 1104 is illustratively about 2.25 mm, but different diameters may be preferred given the requirements of a given facility. The core 1104 is configured to help maintain the structural integrity of the mesh lattice framework while also preventing damage to the mesh ropes over time. For example, the core 1104 minimizes the possibility of rope tearing, etc.

[0047] In one embodiment, the core 1104 is formed by a metal material (such as steel). In another embodiment, the core 1104 is formed by a polymer material. In yet another embodiment, the core 1104 includes a plurality of individual elements (e.g., steel or stainless steel strands) that are coiled together. In this case, a braiding lay of about 18 mm is exemplary suitable. However, it is clearly envisioned that the core 1104 can include different diameters and lays based on the desired thickness and length of the mesh rope 1100.

[0048] Fig.12 1 is a cross-sectional view of a boundary rope 1200 , which is exemplarily consistent with the embodiments of boundary ropes described above with respect to other figures. As shown, the boundary rope 1200 includes six edge rope elements 1202 (an exemplary one is labeled) woven on a boundary rope core 1204 .

[0049] Each edge rope element 1202 is illustratively reinforced internally with a plurality of braided inner wires 1206 that themselves surround a core element. The core element of each rope element 1202 is illustratively a single elongated element (e.g., made of a metal or polymer material) or it itself may be a plurality of braided elongated elements (e.g., braided metal wires). In one embodiment, each edge rope element 1202 includes 7 to 9 inner wires 1206 (e.g., galvanized steel wires) that are braided around the core for reinforcement. In one embodiment, the braiding of the inner wires 1206 has a lay length of about 34 mm. In addition, in one embodiment, each edge rope element 1202 is covered with a braid of a fabric element, such as a braided network of polyester yarns. Each edge rope element 1202 illustratively has a diameter of about 6.6 mm.

[0050] Boundary rope core 1204 is exemplarily formed by metal material (such as steel).In this way, the possibility of tearing and / or otherwise damaging boundary rope 1200 is minimized.In one embodiment, as shown in the figure, boundary rope core 1204 comprises inner wire 1208 braids around center core.For example, boundary rope core 1204 exemplarily comprises the braid of six inner wires 1208 around metal, polymer or braided metal core.In one embodiment, each wire 1208 is formed by steel or stainless steel or galvanized steel.In addition, in one embodiment, boundary rope core 1204 is optionally covered with the braid of fabric element, such as the braided network of polyester yarn.

[0051] Fig.13 1 is a flow chart illustrating an example process 1300 for forming a mesh lattice frame using one or more mesh ropes, embodiments of which are described above with respect to other figures. Operation 1300 begins at block 1310, where a rope segment length parameter is adjusted. Adjusting the rope segment length parameter illustratively includes adjusting consecutive pairs of clamps within a clamping system. Each pair of clamps will illustratively produce a corresponding length of mesh rope. Thus, adjusting the pairs of clamps includes selecting a series of consecutive lengths of mesh rope. For example, Figure 5 The mesh lattice framework shown follows the curved playground framework, so that for different length measurements, different adjacent lengths of the mesh rope will be preferably selected. Therefore, setting the segment length parameter according to block 1310 means setting the pairs of clamps to correspond to the desired continuous lengths of the mesh rope.

[0052] The process 1300 then proceeds to 1320 where the mesh rope (or multiple mesh ropes) are secured to the clamping system. In one embodiment, this means securing the length of the mesh rope to the clamp pairs. In this way, each clamp pair produces and holds a desired length of the mesh rope. In one embodiment, a single length of mesh rope is stretched back and forth across multiple consecutive pairs of clamps and thus covers multiple consecutive lengths of the mesh rope. For example, with respect to Figure 4 The described segment 412 of mesh rope will be secured in one pair of clamps, while the next adjacent segment 414 of mesh rope will go into the next pair of clamps. And so on and so forth.

[0053] The process then proceeds to 1330, where a plurality of mesh clamps (described above with respect to other embodiments) are arranged to receive adjacent segments of mesh rope, each segment being secured in its own pair of clamps. The mesh clamps are illustratively arranged so that when secured to adjacent segments of mesh rope, a desired mesh lattice frame pattern will be produced. For example, the mesh clamps are illustratively arranged to ultimately secure segments of mesh ropes 412 and 414 together.

[0054] Finally, the process ends at 1340, where compression is applied simultaneously to a plurality of mesh clamps so that they are securely crimped in successive segments of the mesh rope, thereby permanently achieving the preferred mesh lattice frame shape. In one embodiment, all mesh clamps for a single pair of adjacent segments of the mesh rope are simultaneously laid out and crimped together. In another embodiment, mesh clamps for multiple adjacent segments of the mesh rope are simultaneously laid out and crimped together. Those skilled in the art will appreciate that any combination of multiple mesh clamps may be laid out and crimped simultaneously.

[0055] FIG. 14A to FIG. 14B (collectively, FIG. 14 ) is a perspective view of a mesh clamp 1600. The mesh clamp 1600 is a double-sided hook—one hook on each side—to accommodate a segment of mesh rope (e.g., Figure 4 4 and 414). As shown, the segments of the mesh rope will not touch each other, but the centerline axes of the segments will be in a common plane. In an embodiment, the mesh fixture is configured so that the segments will touch. Either approach is acceptable depending on the requirements of a given application.

[0056] Each mesh clamp 1600 illustratively includes a first concave portion and a second concave portion 1602 configured to allow insertion of a mesh rope segment. The size of the concave portion 1602 can be determined so that it will ultimately secure the mesh rope segment, wherein there is little to no room for movement after crimping. The mesh hook 1600 further includes one or more teeth 1604 to provide slip resistance after crimping. Further, a barb 1606 is optionally provided to further prevent the mesh rope segment from sliding after being crimped into the concave portion 1602.

[0057] Mesh clamp 1600 Fig. 14B The view actually shows the barb 1606 with the tooth 1604 removed for clarity. Either, both of the features 1604 and 1606 can be included in the mesh clamp 1600 design or neither can be included in the mesh clamp 1600 design. Generally speaking, it is desirable to prevent the mesh rope segment from sliding and / or rotating, and the features 1604 / 1606 will help achieve this. In addition, the two sides of each mesh clamp 1600 further include a first lip portion 1608 and a second lip portion 1610, which are configured to be compressed together and fix the mesh rope segment in the concave portion 1602. This is actually the crimping of the clamp 1600. In one embodiment, the mesh clamp 1600 has a length of about 15 / 16 inches, a height of about 11 / 16 inches, and a relative thickness of about 1 / 4 inches.

[0058] Fig.15is a perspective view of a portion of playground equipment 1700 that illustratively includes a mesh lattice frame 1702 coupled to a frame 1708 . Fig.15 The purpose of this is to demonstrate that there are other ways to attach to playground equipment besides rope hooks. For example, Fig.15 As shown, the mesh lattice frame 1702 is secured to the frame 1708 using a clamping mechanism 1704. In another example, one or more eyebolts 1706 are implemented to secure the mesh lattice frame 1702 to the frame 1708. These are merely examples of other possible connections suitable for coupling the mesh lattice frame 1702 to the frame 1708.

[0059] The mesh rope described herein (comprising Fig.10 Embodiments of the mesh rope 1000 in the embodiment are illustratively configured to include an outer layer (e.g., Fig.10 The braided rope fibers 1002) and the inner layer (e.g., Fig.10 In one embodiment, the outer layer is relatively soft, as it essentially comprises, for example, a fabric material, while the inner layer is more rigid, as it essentially comprises, for example, a metal material. Then, the inner core (e.g., Fig.10 The core 1004 in the mesh extends along the middle of both the outer layer and the inner layer. These three layers interact together to support easy movement of the mesh rope segments relative to each other while still maintaining the long-term shape and structural integrity of the mesh lattice framework. The interaction of the layers of mesh ropes combined with the positioning of the mesh clamps allows the spaces in the mesh lattice framework (e.g., about Figure 1 The shape of the mentioned space 106) is maintained over a long period of time, even when temporarily deformed (for example, when the mesh lattice frame is subjected to pressure from a user).

[0060] In one embodiment, as already described, the inner layer of the mesh rope (e.g. Fig.10 The braided strands 1006 in the mesh rope include a braid of six metal elements surrounding a hidden central core. Each of the six metal elements is actually itself a braid of seven smaller individual strands. Therefore, in this case, a total of 42 strands are used in the inner layer (excluding the central core inside the inner layer). In another example, more than 42 strands are used in the inner layer. In this way, a thicker and more rigid inner layer is formed to provide further protection for the central core and increased overall rigidity of the mesh rope. In one embodiment, the central core located inside the inner layer is then formed of a rigid but flexible material. For example, the central core can be an elongated polymer element. It can be easily deployed as a metal element or even deployed as a braid of metal elements itself.

[0061] The outer layer of the mesh rope (e.g. Fig.10The braided rope fibers 1002 in the mesh rope are exemplarily effective in mitigating environmental conditions, such as temperature changes. It is also relatively soft to the touch. In addition, the outer layer exemplarily provides insulating properties and isolation of the user from the more temperature-sensitive inner layer. The outer layer is exemplarily formed from any of a number of materials. Examples of such materials include: polymer yarns, elastomeric materials, nylon, plastics, or any other material suitable for maintaining the above-mentioned characteristics of the mesh rope. In one example, an adhesive is applied to the outside of the inner layer to support its connection to the outer layer and further contribute to the insulating properties of the outer layer of the mesh rope.

[0062] In some examples, the mesh rope described herein has a diameter of about 6.6 millimeters. However, in other examples, different diameters may also be used. For example, a diameter less than 6.6 millimeters may be used. In this case, it may be best to reduce the spacing between the rows or columns of mesh clamps in the mesh lattice frame. Reduction will promote the optimization of the performance and durability benefits of the mesh lattice frame described herein. In addition, a diameter greater than 6.6 millimeters may also be used. In this case, it may be best to increase the spacing between the mesh clamps in the mesh lattice frame to promote the optimization of the same performance and durability benefits.

[0063] It should be noted that the mesh rope described herein need not be circular or annular in all cases. Other geometric shapes except circular or annular are also possible. For example, the mesh rope can be made into a square, rhombus, hexagon, ellipse or any other shape profile preferred in a given mesh lattice frame design. In one example, no matter how its shape, the breaking strength of the mesh rope is about at least 650 kilograms.

[0064] As already mentioned, the spaces in the mesh lattice framework (e.g. Figure 1 The shape of the space 106 mentioned does not necessarily have to be the same or similar to the shape shown in the figure. The mesh clamp configuration can be adjusted to support different mesh lattice frame spacings, such as square, rectangular, triangle, etc. The vast majority of shapes within a given mesh lattice frame implementation are formed by a combination of four mesh clamps. However, in some examples, fewer or more mesh clamps for forming different mesh lattice frame spaces can be integrated. In one example, the perimeter of each mesh lattice frame space formed in the mesh lattice frame is no more than twenty inches. In this way, the mesh space is large enough to support grasping and / or climbing while preventing climbing through the opening in the mesh lattice frame.

[0065] As shown in the figure above, the space in the mesh lattice frame (e.g., Figure 1The space 106 mentioned is formed using one or more mesh clamps. The mesh clamps are illustratively crimp connectors that bring together segments of mesh ropes that extend parallel to each other. In one embodiment, the mesh lattice frame includes at least three mesh clamps that are all aligned with each other horizontally or vertically. The use of mesh clamps prevents the mesh ropes from overlapping each other, which is common in traditional rope playground climbers. In addition, the mesh clamps as described herein keep the mesh ropes and the clamp connectors aligned substantially parallel to each other (i.e., in the same plane). In one example, the mesh clamps surround approximately 100% of the cross-sectional thickness of the mesh rope and do not form a closed geometric shape. By closing around the mesh rope, the mesh clamp compresses the outer sheath of the mesh rope to minimize slippage.

[0066] In addition to the mesh lattice frame formation, the mesh clamp is also configured to be fixed to the mesh rope, to prevent and / or minimize the mesh lattice frame arrangement from causing damage. In one example, the minimum load capacity of the mesh lattice frame is 20 pounds per square foot. Further, each mesh clamp can be manufactured to have an internal barb feature, and this internal barb feature is configured to clamp the mesh rope, so as to further prevent the mesh rope from sliding. Each mesh clamp is configured so that it increases the friction of the mesh rope, which prevents and / or minimizes the sliding when the mesh clamp is connected with the mesh rope. In one example, the mesh clamp has a minimum skid resistance of 200 pounds that is enough to keep and fix the mesh rope.

[0067] In one example, the mesh ropes described herein for forming a mesh lattice framework include a kink-resistant wrap around a polymer core. For example, when the mesh rope is folded to an angle of about 180 degrees, the mesh rope resists any creases and / or kinks caused by the applied force.
