Description

L31.12-0088SUPPORT COMPONENTS COMPATIBLE WITH FLEXIBLE NET FOR PLAYGROUND DEVICES FIELD OF DESCRIPTION

[0001] The present description relates to devices for playground structures. More specifically, the present description relates to support components to connect portions of the playground to a net lattice of the playground.BACKGROUND

[0002] The design of components for incorporation into playground devices presents unique challenges. Consideration should be given to the fact that playground devices are prone to experiencing delayed maintenance, sometimes with years between part replacements. Consideration should also be given to optimizing to avoid injuries caused, for example, by falls. Playground device components should also be designed to withstand extreme environmental considerations. For example, many regions experience snow and ice in the winter followed by extreme heat and precipitation in the spring / summer. Consideration should also be given to the fact that playground device components are often used by children having little or no supervision. Finally, many if not most playground device components are left out in the open with little or no surveillance, which leaves them open to vandalism. With these and other factors coming into play, it takes an excellent designer to create desirable playground device components. There is an ongoing need for well-designed components from which playground device designers may pick and choose with confidence.SUMMARY

[0003] A playground assembly including a frame component having an elongated channel formed therein and a net lattice formed in part by a net rope. The playground assembly also including a plurality of net clips. Each net clip engages with the net rope when the net lattice is secured to the frame component, and the engagement that each net clip forms with the net rope is substantially concealed within the elongated channel of the frame component.

[0004] These and various other features and advantages that characterize the claimed embodiments will become apparent upon reading the following detailed description and upon reviewing the associated drawings.BRIEF DESCRIPTION OF THE DRAWINGS

[0029] As playground devices become more versatile and entertaining, net type components have become increasingly common. For many playground devices, it is ideal that a net type component comfortably accommodate multiple users of a variety of different sizes. For many playground devices, it is also ideal for a net type component to demonstrate long term strength and durability.

[0030] Additionally, many playground assembly structures include additional support components such as support cables, connectors, bridges, levels, etc. It is ideal that the net type component be able to accommodate these support components for long term strength and durability and to create continuous transitions throughout the playground assembly structure.

[0031] Examples described herein address these and other design considerations for net type playground device components.

[0032] FIG. 1 is a perspective view of a portion of a net lattice 100. Net lattice 100 illustratively includes one or more net ropes 102 distributed at least substantially uniformly to form net lattice 100. Net rope 102 may include a plurality of separate net rope segments, for example segments of same or varying lengths. Alternatively, it may be one continuous net rope 102 having a length sufficient to form some or all of net lattice 100.

[0033] Net lattice 100 also illustratively includes a plurality of net clamps 104. As shown, a network of net clamps 104 are disposed at least substantially uniformly. For example, as shown in FIG. 1, there are groupings of net clamps 104 formed in a line in the horizontal direction (rows of clamps from left-to-right in FIG. 1), and then there are groupings of net clamps 104 formed in a line in the vertical direction (columns of clamps from top-to-bottom in FIG. 1). Each net clamp 104 pulls two portions of net ropes 102 toward one another to form the visually appealing pattern that is inherent to net lattice 100. As is further detailed below, net clamps 104 are in one embodiment configured to secure the portions of net ropes 102 next to one another (may or may not be touching depending on net clamp 104 design) through a crimping style of engagement between the net clampsl04 and the portions of the net ropes 102. However, it is expressly contemplated that other modes of securing together portions of net rope 102 can be utilized (e.g., welding).L31.1 -0088

[0034] As is shown in FTG. 1, the positioning of net clamps 104 relative to one another determines the size, shape, and distribution of spaces incorporated into the pattern of the net lattice 100. An example of a single space so formed in the net lattice 100 is designated in FIG. 1 by reference numeral 106. However, this space 106 is repeated throughout the bulk of net lattice 100, as a result of the substantially uniform distribution of net clamps 104 into aligned columns and rows of net clamps 104. The spaces 106 formed in the lattice 100 can illustratively be modified by changing the relative positioning of the net clamps 104. For instance, by spacing consecutive columns or rows of net clamps 104 closer together, the size of adjacent net spacings 106 will decrease. Of course, it follows logically then that spacing consecutive columns or rows of net clamps 104 further apart will increase the size of adjacent net spacings 106. Further, it is not necessary for net clamps 104 to be consistently aligned into columns or rows. The distribution of net clamps can be organized in infinite combinations so as to produce consistent or even inconsistent spacings 106 throughout net lattice 100. In other examples, net clamps 104 are inconsistently spaced in one or more locations thereby causing variations in the size, shape, and or configuration from one spacing 106 to the next. For example, the spacings 106 across net lattice 100 can just as easily be varied in a consistently or inconsistently organized way depending on the requirements of a given application.

[0035] The securing of net clamps 104 to the portions of net ropes 102 illustratively causes the elongated centerline axis of net ropes 102 to be fixed permanently in a common plane - within each net clamp 104. However, net clamps 104 are adjacent to one another in a common column or row are allowed freedom of movement relative to one another. In this way, net lattice 100 is naturally flexible. Given the described scheme of connecting portions of net ropes 102 together, net lattice 100 is configured overall to respond by conforming to accommodate an applied weight or pressure. In one embodiment, which will be described in greater detail in relation to other Figures, the net ropes 102 are also constructed with a firm but flexible design that causes net lattice 100 then reassume some or all of its original shape and configuration upon relief of the weight or pressure. For example, if a user sits on the net lattice 100, net lattice 100 tolerates a comfortable conformity to the user’s body. Upon the user leaving exiting the net lattice 100, it will illustratively automatically recover some or all of the shape and configuration that it had before the user sat down. Thus, net lattice 100 promotes both sound device for convenient climbing and elasticity for comfortable lounging - all while maintaining the pleasing aesthetic features of the lattice.L31.12-0088

[0036] FTG. 2 is a perspective view of a portion of a net lattice 200. Net lattice 200 includes similarities to the net lattice 100 of FIG. 1, and similar components will be similarly numbered in FIG. 2. One or more net ropes 202 are illustratively connected together in various locations utilizing net clamps 204 so as to form the net lattice 200. Net lattice 200 then further includes a border rope 206 disposed along an outer perimeter of the net lattice 200 to provide support and maintain tension. Border rope 206 illustratively has a larger diameter relative to the one or more net ropes 202. Border rope 206 is configured to support looping portions of net rope 202. As such, the border rope 206 provides termination or transition points 208 for the one or more portions of a net rope 202. Termination or transition points 208 can include any number of loops around border rope 206. However, for many applications, a low number of loops such as 1-3 will provide appropriate structural integrity without adding additional material costs unnecessarily.

[0037] As is also shown in FIG. 2, in one embodiment, a transition loop 210 formed in one or more net ropes 202 is provided to further facilitate an anchoring or transition at border rope 206. In one embodiment, a free, distal end of one or more net ropes 202 is secured at or proximate to a termination or transition point 208. In another embodiment though, net rope 202 is anchored and transitioned at a point 208 without incorporation of any free end - but rather the net rope 202 is transitioned (looped) one or more times around border rope 206 (with or without incorporation of a transition loop 210) before back across the net lattice 200 as a next adjacent segment of net rope 202. In this manner, the entire lattice 200 (excluding border ropes 206, etc.) can be comprised of a single stretch of net rope 202. Additionally, as illustrated in FIG. 2, transition loop 210 and or any portion of a net rope 202 are optionally further secured and / or oriented utilizing one or more extra net clamps 204A. In this way, uncoiling of the terminations or transitions of net rope 202 at border rope 206 is mechanically discouraged.

[0038] FIG. 3 is a perspective view of a portion of a net lattice 300. Net lattice 300 includes similarities to the previously described net lattices 100 and 200, and similar components will be similarly numbered in FIG. 3. Net lattice 300 is particularly similar to net lattice 200 in FIG. 2. Net lattice 300 includes one or more net ropes 302 and net clamps 304 configured to couple together to form the structure and pattern of net lattice 300. Net lattice 300 further includes border rope 306. Portions of net rope 302 have been routed to form a plurality of rope loops 310 (only a representative one has been labeled), wherein rope loops 310 are formed adjacent to where portions of net rope 302 are looped around a border rope 306 forming a number of terminations orL31.1 -0088transitions at a termination or transition point 308. For example, the labeled rope loop 310 illustratively terminates or transitions around border rope 306 two times and is secured in place via a plurality of extra net clamps 304A, as shown. However, in other examples, more or less loops around border rope 306 may be utilized. In this way, uncoiling of the terminations or transitions of net rope 302 about border rope 306 is mechanically discouraged.

[0039] One thing that is different about net lattice 300 is the inclusion of a rope hook 312 to facilitate securing a border rope 306 to a playground device 314. Rope hook 312 is illustratively configured to support border rope 306 within a hooked portion of the rope hook 312. By supporting the border rope 306, rope hook 312 aids in retaining tension across net lattice 300. In one example, rope hook 312 may be compressed or crimped around border rope 306. In other examples, such as those described below in relation to other Figures, border rope 306 is securely locked in rope hook 312 by fastening pressing it into the hooked portion of rope hook 312 and then securing it with a hook cover (not shown in FIG. 3).

[0040] In one embodiment, rope hook 312 is coupled to device 314 by welding. However, it is expressly contemplated that other modes of coupling rope hook 312 to device 314 may be utilized. Through incorporation of one or more rope hooks 312, the border rope 306 and therefore net lattice 300 may be secured and coupled to most any playground device. Those skilled in the art will appreciate that there are other suitable ways other than a rope hook to couple the net lattice embodiments described herein to a playground device - such as but not limited to clamping or through the incorporation of eyebolts or other similar connectors that may or may not require welding.

[0041] FIG. 4 is a perspective view of a portion of a net lattice 400. Net lattice 400 includes similarities to the previously described net lattices 100, 200 and 300, and similar components will be similarly numbered in FIG. 4. Net lattice 400 is particularly similar to net lattice 200 in FIG. 2. Net lattice 400 includes one or more net ropes 402 and net clamps 404 configured to form the structure and pattern of the net lattice 400. A border rope 406 illustratively supports an outer perimeter of net lattice 400. The border rope 406 supports the one or more net ropes 402. In one embodiment, net clamps 404 are positioned and configured to guide net ropes 402 into a clinching engagement with border rope 406 that limits or prohibits rubbing or other abrasive action between the net rope 402 and border rope 406. As such, the shape of openings in net lattice 400 may or may not be as consistent as the shape of openings further away from the border rope 406.L31.12-0088

[0042] Tn one embodiment, as shown in FTG. 4, net rope 402 has no loose end but instead terminates or transitions (i.e., loops) one or more times around border rope 406 before continuing in an opposite direction to form an adjacent run of rope 402 in the overall net lattice 400 structure. For example, in one embodiment, a segment of net rope 412 runs towards border rope 406 and terminates or transitions (i.e., loops) about border rope 406 a number of times (e.g., two times) before proceeding in an opposite direction as another segment 414. Segment 412 and segment 414 are clamped together by net clamps 404 (may or may not touch one another depending on net clamp 404 design). This routing of net rope 402 towards and away from border rope 406 plus the clamping with net clamps 404 produces the shape of net lattice 400, as shown. All of this being said, it is also contemplated that individual portions of net rope 402 could be utilized instead of the illustrated continuous rope 402 design.

[0043] Additionally, as shown in FIG. 4, border rope 406 is secured to a playground device 410 by a plurality of rope hooks 408. Rope hooks 408 may be secured to playground device 410 by, for example, welding. However, it is expressly contemplated that other means of fixing rope hooks 408 to device 410 may be utilized in the alternative. In operation, the plurality of rope hooks 408 secure border rope 406 to playground device 410, thereby providing sufficient tension and integrity of net lattice 400 as an integral component of the broader playground installation of which playground device 410 is a part.

[0044] FIG. 5 is a perspective view of a playground device 500 that incorporates a net lattice 502. Net lattice 502 is illustratively configured so as to be consistent with the embodiments of net lattices described in relation to any of the previous Figures 1-4. As shown, net lattice 502 generally covers an interior space within a device frame 504. A border rope 510 is configured to provide support within the net lattice 502 structure and also facilitates a coupling to the device frame 504. Border rope 510 is secured to frame 504 utilizing a plurality of rope hooks 512.

[0045] In one embodiment, frame 504 includes one or more curved portions 506. In another embodiment, straight portions are included as well, such as straight portion 508. In either case, border rope 510 is illustratively configured to have sufficient pliability to line the perimeter of both curved portion 506 and / or straight portion 508 while retaining the tension across the net lattice 502. Those skilled in the art will then appreciate that the size, shape and configuration of the playground device and corresponding net lattice features can change depending on the requirements for a given playground installation.L31.1 -0088

[0046] FTG. 6 is a perspective view of a rope hook 600. As shown, rope hook 600 includes a concave portion 602 configured to house and support a border rope, such as the examples of border ropes described above relation to other Figures. Concave portion 602 is illustratively sized sufficiently to fit any border rope that fulfills applicable requirements for a given installation. Rope hook 600 further includes a lip portion 604 configured to further secure and retain the border rope within concave portion 602. Additionally, in one embodiment, rope hook 600 includes a smooth portion 606 and jagged portion 608 disposed within concave portion 602. Jagged portion 608 is configured to further secure the border rope by applying a frictional, digging or drag force to prevent rotation and / or translation of the border rope within concave portion 602. In one embodiment, rope hook 600 further includes surface 610 which configured to couple to a desired playground device. As shown, surface 610 is generally depicted as flat in order to allow for suitable coupling to the playground device. For example, rope hook 600 may be coupled to a playground device at surface 610 by welding surface 610 to the playground device. However, in other embodiments, surface 610 may be curved in any suitable manner to allow for fitting of rope hook 600 to a playground device. 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 expressly contemplated that a different length and thickness may be utilized as well. Additionally, in one embodiment, rope hook 600 includes aperture 612. Aperture 612 is configured to receive one or more fasteners therein. The fasteners may be used, for example, to secure a hook cover onto rope hook 600. The fastener used in aperture 612 may be, for example, a bolt, screw, or any other fastener suitable for protrusion into aperture 612. In one embodiment, aperture 612 is a threaded aperture appropriate for a corresponding threaded fastener.

[0047] FIGS. 7A and 7B are perspective views of a hook cover 700. Hook cover 700 includes an internal portion 702 configured to receive a rope hook therein. The rope hook may be, for example, the rope hook 600 described above with respect to FIG. 6. Internal portion 702 includes a first gap 704 configured to facilitate engagement of a lip portion of the rope hook to hook cover 700, and a second gap 706 configured to facilitate engagement of a body portion of the rope hook to hook cover 700. Hook cover 700 may, in one embodiment, have a length of about 2.25 inches, a height of about 1 and 13 / 16 of an inch, and a width of about 1.125 inches. Additionally, hook cover 700 further includes an aperture 708 configured to allow insertion of a fastener therethrough. In installation, the fastener illustratively protrudes through aperture 708 andL31.12-0088additionally through the aperture provided in the rope hook in order to couple hook cover 700 and the rope hook together. The fastener utilized may be, for example, a bolt, screw, or any other fastener suitable for protrusion though aperture 708. In one embodiment, aperture 708 is a threaded aperture. Additionally, in one embodiment, aperture 708 has a diameter of about 0.410 inches. In operation, hook cover 700 is configured facilitate a housing of the rope hook and provide a protective barrier from any intentional or accidental damage to the rope hook and / or a border rope that is supported by the rope hook.

[0048] FIG. 8 is a perspective view of a playground device 800 incorporating elements described above in relation to other Figures. Device 800 includes a net lattice 802 having a plurality of net clamps 804 and one or more border ropes 806. Border rope 806 is 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 consistent with the hook cover described above with respect to FIGS. 7A-7B. The hook cover shown serves to further fasten border rope 806 to rope hook 808 while discouraging tampering. Additionally, as shown, rope hook 808 protrudes slightly outside of the hook cover such that it may be coupled to frame 810, such as but not limited to being secured by welding.

[0049] FIGS 9A-9B are perspective views of a rope hook coupling assembly 900. Assembly 900 includes a rope hook 902 fastened to hook cover 904. As shown, a border rope 906 extends through a concave portion of rope hook 902 and hook cover 904 such that it is secured into place. Border rope 906 and / or rope hook 902 are illustratively sized such that there is little to no gap for movement when border rope 906 is secured within the concave portion of rope hook 902.

[0050] Also shown in FIGS. 9A-9B is a cross section of border rope 906. As shown, border rope 906 illustratively includes six edge ropes 920 and a rope core 910. However, in another example, a different number of edge ropes and / or rope cores may be utilized. In one embodiment, the rope edges are reinforced, for example, with steel wire. Additionally, in one embodiment, rope core 910 is a steel core, but could just easily be comprised of a different material such as a polypropylene core material. In one embodiment, the material is selected to make it difficult to tear and / or otherwise damaging border rope 906. In one embodiment, the diameter of border rope 906 is about 20 millimeters (mm). Additional embodiments configurations for the composition of border rope 906 will be discussed below in relation to FIG. 11.L31.1 -0088

[0051] Assembly 900 additionally includes one or more fasteners 908 configured to protrude through aperture 912 and fasten hook cover 904 to rope hook 902. As illustrated, two fasteners 908 are used, wherein each fastener is applied on opposite side of rope hook 902 and hook cover 904. However, in other embodiments, one fastener may be used with aperture 912. Fasteners 908 may be, for example, threaded fasteners. However, in other embodiments, other fasteners may be used, such as a non-threaded fastener.

[0052] FIG. 10 is a sectional view of a net rope 1000. In one embodiment, net rope 1000 is the net rope or ropes used to form the net lattice embodiments described above in relation to other Figures. Net rope 1000 illustratively includes a plurality of woven rope fibers 1002 that surround a rope core 1004 that is difficult to see in FIG. 10 because it is itself surrounded by a plurality of woven strands 1006. In one embodiment, each woven strand 1006 and / or rope core 1004 is itself a weave of individual strands. However, for now, it is useful for the purpose of the present description to think of woven strands 1006 and rope core 1004 as each individual elements in their own right.

[0053] As was alluded to in the description of previous Figures, one or more net ropes 1000 are coupled together utilizing a plurality of net clamps so as to form a net lattice. The outer weave of rope fibers 1002 serves to protect the woven strands 1006 and the rope core 1004 from damage, while also providing a comfortable lounging and functional climbing surface for playground component users. Further, rope fibers 1002 also isolate playground users from the what would be relatively sharper, hotter, colder and otherwise uncomfortable to the touch woven strands 1006 and / or rope core 1004. In one embodiment, rope fibers 1002 are formed of braided polyester. However, in other embodiments, another material may be used to form rope fibers 1002 (e.g., polyethylene).

[0054] The woven strands 1006 and rope core 1004 together are configured to further discourage damage to the one or more net ropes 1000 over time. For instance, woven strands 1006 and rope core 1004 together reduce the likelihood that the one or more net ropes 1000 will outright break, tear be cut through or be compromised in some way by a vandal. Additionally, the relative rigidity of woven strands 1006 and rope core 1004 causes the structural integrity and shape of the net lattice to be maintained when it is not under pressure while also allowing for temporary shape change when the net lattice is under pressure such as by a user comfortably laying upon the net lattice. The relative rigidity of the woven strands 1006 and rope core 1004 in combination withL31.1 -0088their positioning in the rope clamps of the net lattice cause a degree of shape memory functionality, wherein the net lattice will deform when under pressure but naturally and automatically will return partially or completely to a non-deformed shape when not under pressure.

[0055] FIG. 11 is a cross-sectional view of a net rope 1100, which is illustratively consistent in all or most ways with net rope 1000. In other words, in one embodiment, the cross-sectional view is a cross section of net rope 1000. As shown, net rope 1100 includes an outer layer 1102 comprised of 12 (not by limitation) individually woven rope fibers (these were referred to as rope fibers 1002 in relation to FIG. 10). In one embodiment, the rope fibers of outer layer 1102 are formed of a polyester material. In another example, the rope fibers may be comprised of a fabric or some other relatively soft material (i.e., soft relative to the more rigid materials around which it is woven).

[0056] The diameter of net rope 1100 is defined by the overall diameter of outer layer 1102. For example, the diameter is approximately 6.6 millimeters (mm). However, it is expressly contemplated that net rope 1100 may have a larger or smaller diameter depending on the requirements of a given installation. A diameter in the range of 5-18 mm is effective to balance comfort for laying on with function for an appealing climbing experience. A diameter of less than 12 is especially effective for a shape memory effect wherein net lattice shape is automatically reassumed when pressure is removed (e.g., a lounging person exists). In one embodiment the overall net rope 1100 is dipped or coated in a protective material to further reduce the likelihood of fraying, etc. Such a coating though will be light and unlikely to add significantly to the diameter.

[0057] Net rope 1100 also includes inner layer 1106 comprised of six (not by limitation) individually braided strands (referred to in FIG. 10 as woven strands 1006) that are comprised of a more rigid material, such as a metallic material. Inner layer 1106 may or may not also be dipped or coated in a light protective layer. The 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 can be selected depending upon the requirements of a given application.

[0058] Finally, net rope 1100 further includes a rope core 1104 (referred to as rope core 1004 in FIG. 10) disposed within outer layer 1102 and inner layer 1106. The diameter of rope core 1104 is illustratively about 2.25 mm, though different diameters may be preferrable given the requirements of a given installation. Rope core 1104 is configured to help retain structural integrityL31.12-0088of the net lattice while also preventing damage to the net rope over time. For instance, rope core 1104 minimizes the likelihood of rope tearing, etc.

[0059] In one embodiment, rope core 1104 is formed from a metal material, such as steel. In another embodiment, rope core 1104 is formed of a polymeric material. In still another embodiment, rope core 1104 comprises a plurality of individual elements (e.g., steel or stainless-steel strands) coiled together. In that case, a woven lay length of about 18 mm is illustratively suitable. However, it is expressly contemplated that rope core 1104 may include a different diameter and lay length based on the desired thickness and length of net rope 1100.

[0060] FIG. 12 is a cross-sectional view of a border rope 1200, which is illustratively consistent with embodiments of border ropes described above in relation to other Figures. As shown, border rope 1200 includes six edge rope elements 1202 (an illustrative one has been labeled) woven over a border rope core 1204.

[0061] Each edge rope element 1202 is illustratively reinforced internally with a plurality of woven internal 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 metal or polymeric material) or itself can be a plurality of woven elongated elements (e.g., woven metal wires). In one embodiment, each edge rope element 1202 includes between 7 and 9 internal wires 1206 (e.g., galvanized steel wires) woven around the core for reinforcement. In one embodiment, the weave of internal wires 1206 has a lay length of about 34 mm. Additionally, in one embodiment, each edge rope element 1202 is covered with a weave of fabric elements, such as a woven network of polyester yams. Each edge rope element 1202 illustratively has a diameter of about 6.6 mm.

[0062] Border rope core 1204 is illustratively formed of a metal material, such as steel. In this way, the possibility of tearing and / or otherwise damaging border rope 1200 is minimized. In one embodiment, as shown, border rope core 1204 is comprised of a weave of internal wires 1208 surrounding a central core. For example, border rope core 1204 illustratively includes a weave of six internal wires 1208 around a metal, polymeric, or woven metal core. In one embodiment, each wire 1208 is formed of steel or stainless steel or galvanized steel. Additionally, in one embodiment, the border rope core 1204 is optionally covered with a weave of fabric elements, such as a woven network of polyester yarns.

[0063] FIG. 13 is a flow diagram showing an example process 1300 for forming a net lattice utilizing one or more net ropes, embodiments of the net lattice and net rope being described aboveL31.1 -0088in relation to other Figures. Operation 1300 begins at block 1310 where rope segment length parameters are adjusted. Adjusting rope segment length parameters illustratively comprises adjusting consecutive pairs of clamps within a clamping system. Each pair of clamps will illustratively produce a corresponding length of net rope. Thus, adjusting the pairs of clamps comprises selecting a consecutive series of lengths of net rope. For example, the net lattice shown in FIG. 5 follows a curved playground frame and, as such, different adjacent lengths of net rope will desirably be selected for different measurements of length. Setting the segment length parameters in accordance with block 1310 therefore means setting the pairs of clamps to correspond to desired consecutive lengths of net rope.

[0064] Process 1300 then proceeds to 1320 where the net rope (or net ropes) is secured into the clamping system. In one embodiment, this means securing lengths of the net rope into the clamp pairs. As such, each clamp pair produces and holds a desirable length of net rope. In one embodiment, a single stretch of net rope is stretched back and forth across multiple consecutive pairs of clamps, and therefore covering multiple consecutive lengths of net rope. For example, segment 412 of net rope described in relation to FIG. 4 would be secured in one pair of clamps while the next adjacent segment 414 of net rope would go into the next pair of clamps. And so on and so forth.

[0065] The process then proceeds to 1330 where a plurality of net clamps, which have been described above in relation to other embodiments, are arranged so as to receive adjacent segments of net rope, each secured in their own pair of clamps. The net clamps are illustratively laid out such that when secured to adjacent segments of net rope the desired pattern of the net lattice will be produced. For example, net clamps are illustratively laid out to eventually secure segments of net rope 412 and 414 together.

[0066] Finally, the process ends with 1340 where compression is simultaneously applied to the plurality of net clamps causing them to securely crimp in consecutive segments of net rope, thereby permanently effectuating the preferred net lattice shape. In one embodiment, all of the net clamps for a single pair of adjacent stretches of net rope are laid out and collectively crimped all at once. In another embodiment, the net clamps for multiple adjacent stretches of net rope are laid out and crimped together simultaneously. Those skilled in the art will appreciate that any combination of multiple net clamps can be simultaneously laid out and crimped.L31.12-0088

[0067] FIGS. 14A-14B (collectively FIG. 14) are perspective views of a net clamp 1600. Net clamp 1600 is a two-sided hook - one hook on each side to accommodate a segment of net rope on each side (e.g., segments 412 and 414 shown in FIG. 4). As shown, the segments of net rope will not touch one another but the center line axis of each will be brought into a common plane. In one embodiment, the net clamp is configured such that the segments will touch. Either way is acceptable depending on the requirements of a given application.

[0068] Each net clamp 1600 illustratively includes first and second concave portion 1602 configured to allow insertion of a net rope segment. Concave portion 1602 may be sized such it will eventually secure the net rope segment with little to no room for movement after crimping. Net hook 1600 further includes one or more teeth 1604 to provide slip resistance after crimping. Further a barb 1606 is optionally provided to further discourage net rope segments from slipping once crimped into a concave portion 1602.

[0069] The FIG. 14B view of net clamp 1600 actually shows the barb 1606 with teeth 1604 removed, for the purpose of clarity. Either, both, or none of features 1604 and 1606 can be included in the net clamp 1600 design. In general, it is desirable to prevent slippage and / or rotation of the net rope segments and features 1604 / 1606 will help with that. Additionally, both sides of each net clamp 1600 further include a first lip portion 1608 and second lip portion 1610, which are configured to compress together and secure a net rope segment within the concave portion 1602. This is effectively the crimping of the clamp 1600. In one embodiment, net clamp 1600 has a length of about 15 / 16 of an inch, with a height of about 11 / 16 of an inch and a relative thickness of about 1 / 4 of an inch.

[0070] FIG. 15 is a perspective view of a portion of a playground device 1700 illustratively includes a net lattice 1702 coupled to a frame 1708. The purpose of FIG. 15 is to demonstrate the point that there are ways other than a rope hook to couple to a playground device. For example, as shown in FIG. 15, a clamping mechanism 1704 is utilized to secure net lattice 1702 to frame 1708. In another example, one or more eyebolts 1706 are implemented to secure net lattice 1702 to frame 1708. These are just examples of other possible connections suitable for coupling net lattice 1702 to frame 1708.

[0071] Embodiments of net ropes described herein, including net rope 1000 in FIG. 10, are illustratively configured so as to include an outer layer (e.g., woven rope fibers 1002 in FIG. 10) and an inner layer (e.g., woven strands 1006 in FIG. 10). In one embodiment, the outer layer isL31.1 -0088relatively soft because it is substantially comprised of, for example, a fabric material while the inner layer is more rigid because it is substantially comprised of, for example, a metal material. An inner core (e.g., core 1004 in FIG. 10) then runs down the middle of both of the outer and inner layers. These three layers interact together so as to support easy movement of net rope segments relative to each other while still maintaining the long-term shape and structural integrity of the net lattice. The interaction of the layers of the net rope in combination with positioning of the net clamps causes the shape of spaces in the net lattice (e.g., spaces 106 referred in relation to FIG. 1) to be preserved long term even when temporarily deformed, for example, when the net lattice is placed under pressure by a user.

[0072] In one embodiment, as has been described, the inner layer (e.g., woven strands 1006 in FIG. 10) of a net rope includes a weave of six metallic elements around a concealed central core. Each of the six metallic elements is actually itself a weave of seven smaller individual strands. Thus, in this case, 42 total strands are utilized in the inner layer (not including the central core inside of the inner layer). In another example, more than 42 strands are utilized in the inner layer. In this way, a thicker and more rigid inner layer is formed to provide further protection of the central core and an increased overall rigidity of the net rope. In one embodiment, the central core that then lies inside of the inner layer is formed of a rigid yet flexible material. For example, the central core may be an elongated polymeric element. It could just as easily be deployed as a metallic element or even a weave of metallic elements in its own right.

[0073] The outer layer (e.g., woven rope fibers 1002 in FIG. 10) of the net rope is illustratively effective to moderate environmental conditions, such as temperature changes. It is also relatively soft to the touch. Additionally, the outer layer illustratively provides insulative properties and user isolation from the more temperature sensitive inner layer. The outer layer is illustratively formed from any of a number of materials. Examples of such materials include: a polymeric yam, elastomeric material, nylon, plastic, or any other material suitable for retaining the aforementioned features of the net rope. In one example, an adhesive is applied outside of the inner layer in order to support its connection to the outer layer and further contribute to the insulative properties of the outer layer of the net rope.

[0074] In some examples, the net ropes described herein have a diameter of about 6.6 millimeters. However, in other examples, a different diameter can be utilized as well. For instance, a diameter smaller than 6.6 millimeters can be utilized. In this case, the spacing between rows orL31.12-0088columns of net clamps in the net lattice is perhaps best if reduced. A reduction will promote optimization of the performance and durability befits of the net lattice as described herein. Additionally, a diameter larger than 6.6 millimeters can also be utilized. In this case, the spacing between net clamps in the net lattice is perhaps best if increased in order to promote optimization of the same performance and durability benefits.

[0075] It should be noted that the net ropes described herein need not be round or circular in all instances. Geometric shapes other than round or circular are possible. For example, the net ropes can be produced with a square, diamond, hexagonal, oval, or any other shape profile preferred in a given net lattice design. In one example, the breaking strength of the net rope, without regard to its shape, is approximately at least 650 kilograms.

[0076] As has been alluded to, the shape of spaces in the net lattice (e.g., spaces 106 referred in relation to FIG. 1) need not necessarily be the same or similar to the shapes showed in the Figures. The net clamp configuration can be adjusted to support different net lattice spacings such as square, rectangular, triangular, etc. The vast majority of the shapes within a given net lattice implementation are formed via a combination of four net clamps. However, in some examples, less or more net clamps can be integrated used to form different net lattice spaces. In one example, the perimeter of each net lattice spaces formed within the net lattice is no larger than twenty inches. In this way, the net spaces are large enough to support grappling and / or climbing while preventing climbing through the openings in the net lattice.

[0077] As indicated above in relation to the Figures, the spaces in the net lattice (e.g., spaces 106 referred in relation to FIG. 1) are formed using one or more net clamps. The net clamps are illustratively crimped-style connectors that bring together segments of net rope that run parallel to one another. In one embodiment, the net lattice includes at least three net clamps all in-line with one another either horizontally or vertically. Utilizing the net clamps enables the net ropes to not overlap over one another, which is common in traditional rope style playground climbers. Also, the net clamps as described herein enable net ropes and clamp connectors to remain in substantially parallel alignment (i.e., in the same plane) alignment with one another. In one example, the net clamps encompass approximately 100% of the net rope cross sectional thickness and do not form a closed geometric shape. By closing around the net rope, the net clamp compresses the outer jacket of the net rope in order to minimize slipping.L31.1 -0088

[0078] Tn addition to net lattice formation, the net clamps are configured to secure to the net ropes to prevent and / or minimize damage to the net lattice arrangement. In one example, the minimum load capacity of the net lattice is 20 pounds per square foot. Further, each net clamp can be produced with an interior barb feature configured to grip the net rope in order to further prevent slipping of the net rope. Each net clamp is configured such that it adds friction to the net rope, which prevents and / or minimizes slipping while the net clamp is coupled to the net rope. In one example, the net clamp has a minimum slip resistance of 200 pounds, sufficient to retain and secure the net rope.

[0079] In one example, the net ropes described herein as used to form the net lattice include a kink resistant wrap surrounding a polymeric central core. For instance, when folding the net rope to an angle of about 180 degrees, the net rope resists any creasing and / or kinking from the applied force.

[0080] FIG. 16 is a perspective view of a first side of a net lattice having a mount according to one example. As shown in FIG. 16, net lattice 1800 includes net rope 1803 and one or more net clamp(s) 1804. In one example, net lattice 1800 is similar to or the same as net lattice 100, net lattice 200, net lattice 300, and / or net lattice 400 as discussed above. For example, net rope 1803 can include a singular net rope woven back and forth through one or more net clamp(s) 1804. In one example, net rope 1803 can be similar to or the same as net rope 102, 202, 302, and / or 402 and net clamp(s) 1804 can be similar to or the same as rope clamp 104, 204, 304, and / or 404, as discussed above.

[0081] Mount 1802 is connected to net lattice 1800. Mount 1802 can be permanently or temporarily secured to net lattice 1800. Accordingly, mount 1802 can be fixed to a specific location on net lattice 1800, or the same mount 1802 can be moved to different locations on net lattice 1800, depending on specific installation considerations (e.g., playground structure considerations, etc.). Mount 1802 is positioned proximate to space 1806 of net lattice 1800. Space 1806 is formed by net clamp(s) 1804 spaced apart on net rope 1803, which forms a pattern of net lattice 1800. In one example, space 1806 is formed by four net clamps 1802 and the corresponding portion of net rope 1803. In one example, mount 1802 is connected to net lattice 1800 between four (4) corresponding net clamps 1804, such that mount 1802 engages the corresponding portion of net lattice 1800. In some examples, mount 1802 can overlap with one or more net clamps 1804 and / or portions of net lattice 1800.L31.12-0088

[0082] Mount 1802 can be disposed within space 1806 of net lattice 1800 and / or can made to cover a substantial portion of space 1806 of net lattice 1800. In one example, mount 1802 can cover all of space 1806 and / or can extend into a neighboring space formed in the pattern of net lattice 1800. In one example, mount 1802 is positioned and secured over rope 1803 and net clamp(s) 1804, such that mount 1802 clamps onto rope 1803 and net clamp(s) 1804.

[0083] As shown, mount 1802 houses cable 1808. In one example, cable 1808 is made of a firm yet flexible material composition. Cable 1808 can include a single material or can include a combination of materials. For example, cable 1808 can include a metal core (e.g., steel, copper, alloys, etc.) surrounded by a sheathing (e.g., polyethylene, nylon, rubber, etc.), and / or other components. Cable 1808 can also be made with a square, diamond, hexagonal, oval, or other shape profile. In one example, cable 1808 is used to connect net lattice 1800 to a structural component of a frame, such as a playground frame (e.g., device frame 504). In another example, cable 1808 connects net lattice 1800 to a different component, such as a separate net lattice. In another example, the different component connected to cable 1808 is a play feature associated with a playground structure.

[0084] As shown in FIG. 16, cable 1808 enters into mount 1802. Body portion 1807 of mount 1802 includes aperture 1805 which receives cable 1808. In one example, cable 1808 passes through aperture 1805 of mount 1802 (shown in FIG. 17). For instance, cable 1808 enters, passes through, and exits mount 1802 in a substantially perpendicular manner. Mount 1802 provides a more controlled and predictable way for cable 1808 to pass-through net lattice 1800. In another example, mount 1802 is configured to receive an end of cable 1808, such that cable 1808 does not pass entirely through mount 1802. For example, mount 1802 can be a termination point for cable 1808. Ultimately, mount 1802 forms a female connection component for a male connection component (i.e. cable 1808) or vise versa.

[0085] Net lattice 1800 can include a plurality of mounts 1802 for a variety of different applications and cable 1808 can support net lattice 1800 during different applications. For example, a weight (e.g., from a user) can be applied to net lattice 1800 and cable 1808 can provide tension assistance when net lattice 1800 experiences a significant weight in a compact location. Cable 1808 can also provide net lattice 1800 with load absorption and / or shock dampening assistance when a load (e.g., from a user) is applied to net lattice 1800. For example, if a user isL31.12-0088climbing on net lattice 1800, cable 1808 can absorb some of the load (i.e. weight) applied by the user on net lattice 1800.

[0086] FIG. 17 is a pictorial view of a second side of net lattice 1800 having a second side of mount 1802 according to one example. Similar to FIG. 16, FIG. 17 shows net lattice 1800 which includes net rope 1803, net clamp(s) 1804, and mount 1802. FIG. 17 also demonstrates how mount 1802 can be adjusted relative to net lattice 1800. For example, as shown in FIG. 17, mount 1802 is not entirely set onto net lattice 1800, to illustratively show channel system 1813 of mount 1802. Net lattice 1800 can be adjusted to couple to mount 1802, such that the corresponding portion of net lattice 1800 fits within channel system 1813 of mount 1802 (discussed in more detail with regard to FIGS. 18A-18B).

[0087] In one example, FIG. 16 illustrates a first side of net lattice 1800, while FIG. 17 illustrates a second side of net lattice 1800. Similarly, FIG. 16 illustrates a first side of mount 1802, while FIG. 17 illustrates a second side of mount 1802. The second side of mount 1802 can be coupled to the first side of mount 1802 via fastener 1811. Therefore, cable 1808 passes through net lattice 1800 in a substantially perpendicular manner. Mount 1802 assists in aligning cable 1808 as it passes through net lattice 1800. In one example, a net system includes multiple net lattices (e.g„ multiple of net lattice 1800) stacked in vertical sequence, and each net lattice includes a set of corresponding mounts (e.g., multiple of mount 1802) in vertical alignment. For instance, a single continuous cable runs through each net lattice in sequence. In this example, cable 1808 extends through mount 1802 on net lattice 1800 and continues to an additional mount of an additional net lattice, which can ultimately link the net lattices. As a result, net lattice 1800 and the additional net lattice are in operative communication that, in one example, forms an interconnected net system. It is expressly contemplated that alternative configurations can be employed.

[0088] FIG. 18A is an exploded view of mount 1900 according to one example. FIG. 18B is an exploded view of mount 1900 according to one example. FIG. 18A and FIG. 18B include similar components. Similar components are numbered accordingly and FIG. 18A and FIG. 18B are discussed below in unison. Mount 1900 can be similar to or the same as mount 1802 as discussed above. As shown in FIG. 18A, mount 1900 is a pass-through mount.

[0089] Mount 1900 includes base 1902, top segment 1904, and bushing 1906. Base 1902 and top segment 1904 form a body section of mount 1900. In one example, top segment 1904 can be split into first section 1907 and second section 1909. For instance, a two-part top segment 1904L31.12-0088can assist mount installation and / or assembly. When first section 1907 and second section 1909 are connected to form top segment 1904, an aperture can be formed therethrough.

[0090] In one example, base 1902 and / or top segment 1904 are made of cast aluminum pieces. In one example, bushing 1906 is made a plastic material formed by a manufacturing process (e.g., injection molding). Top segment 1904 includes a structure having section 1908 which extends toward and into base 1902. In one example, section 1908 has a cylindrical shape. In other examples, section 1908 has a different shape such as cubic, conical, hexagonal, or other shape. Top segment 1904 also includes lip 1905. Lip 1905 can include a beveled edge which allows cable to freely rotate within mount 1900 at different angles relative to top segment 1904. In one example, lip 1905 is positioned on both the top and bottom side (i.e. near section 1908) of the top segment 1904.

[0091] Bushing 1906 is positioned within mount 1900 and is configured to receive an elongated component (i.e. a rope, cable, etc.). Once mount 1900 is assembled, bushing 1906 is positioned within top segment 1904, as shown in FIGS. 16-17. Thus, top segment 1904 forms a housing around bushing 1906. In other words, bushing 1906 is substantially concealed within mount 1900. Bushing 1906 is configured to guide an elongated component (e.g., cable 1808) through mount 1900. As shown in FIG. 18A and FIG. 18B, bushing 1906 is a pass-through bushing designed to facilitate the passage of a cable through mount 1900. Alternatively, bushing 1906 can be a closed bushing that acts as a termination point for a cable (described in more detail with regard to FIG. 19). Bushing 1906 provides a more controlled and predictable passage of the cable through a net lattice (e.g., net lattice 1800). As shown, bushing 1906 has a spherical shape. In one example, this spherical shape allows a cable to pass through mount 1900 at various angles without requiring alignment or rotation of mount 1900 itself. Thus, bushing 1906 can move independently from mount 1900. For example, as shown above in FIG. 16-17, bushing 1906 can include a diameter smaller than the diameter of lip 1905 of top segment 1904. This allows bushing 1906 to be secured within mount 1900 while retaining an ability to pivot or move slightly in response to cable motion. In one example, this reduces the stress and / or contusion of mount 1900 relative to a net lattice.

[0092] As previously mentioned, mount 1900 includes base 1902. Base 1902 is made to receive section 1908 of top segment 1904, and therefore mate with top segment 1904. In one example, aperture 1912 receives section 1908. Aperture 1912 includes a shape that matches or is associated with the shape of section 1908. As shown, aperture 1912 is positioned in the center ofL31.1 -0088base 1902 and extends through base 1902, such that a passage is formed. Tn other examples, aperture 1912 is offset from the center of mount 1900. Aperture 1912 can also include a beveled edge.

[0093] Base 1902 includes first side 1920 and second side 1922. In one example, first side 1920 is the top side of base 1902, and second side 1922 is the bottom side of base 1902. First side 1920 includes aperture 1912, guide(s) 1924, and fastener passage(s) 1926. Second side 1922 includes aperture 1912 and fastener passage(s) 1926. In one example, guide(s) 1924 are configured to secure a rope of a net lattice when mount 1900 is positioned on a net lattice, as discussed above. For example, mount 1900 can be shaped to fit within a space formed within a net lattice. Thus, guides 1924 receive each respective side of the rope section defining the space. As shown, guides 1924 form a channel or groove system to receive the ropes of a net lattice. In one example, a net lattice includes a space formed by four segments of the net rope. Therefore, the space has four sides (i.e. four rope portions) forming the perimeter of the space, and guide(s) 1924 can receive the four rope portions. Base 1902 can also be shaped to match any shaped space in a net lattice. In another example, with a net lattice space having a shape with a different number of sides (e.g., 6 sides), guide(s) 1924 are made accordingly (i.e. six guides 1924 are included). It is expressively contemplated that any number of sides can be received by guides 1924. Accordingly, mount 1900 can act as a support within a net lattice to keep consistency between the spaces formed within the net lattice.

[0094] As shown in FIG. 18A, fastener passage(s) 1926 are also included in base 1902. Fastener passage(s) 1926 can receive fastener(s) 1928. Fastener(s) 1928 secure base 1902 to top segment 1904. As shown in FIG. 18B, fastener(s) 1928 extend through base 1902 and into fastener aperture(s) 1930 of top segment 1904. In one example, fastener(s) 1928 are bolts or screws with threaded features that are secured within fastener aperture(s) 1930. Base 1902 can be fixed to top segment 1904.

[0095] In one example, when mount 1900 is assembled on a net lattice (e.g., net lattice 1800), base 1902 is positioned on a first side of the net lattice, the rope of the net lattice is set into guide(s) 1924, top segment 1904 is placed on top of base 1902, and fastener(s) 1928 are deployed to secure mount 1900 in place on the net lattice. Additionally, a cable can be inserted into or through mount 1900 during or after the assembly process. In one example, the cable can be made of a smaller diameter compared to the diameter of bushing 1906 and top segment 1904. In thisL31.1 -0088example, mount 1900 is loose-fitting on the cable and allows the cable to move in a vertical direction (i.e. up and down relative to the net lattice plane) but restricts movement in the lateral direction (i.e. left and right relative to the net lattice plane). In one example, the vertical direction is substantially perpendicular to the plane of the net lattice. In a different example, the vertical direction is angled relative to the place of the net lattice. As discussed, lip 1905 and bushing 1906 allow the cable to move and tilt independent of mount 1900.

[0096] FIG. 19 is an exploded view of mount 1950 according to one example. Mount 1950 can be similar to mount 1802 and / or mount 1900 as discussed above. Mount 1950 can as a termination point for an end of a cable (instead of a passage for the cable). For example, mount 1950 does not allow a cable to pass-through and thus forms an end point of the cable. Mount 1950 includes bushing 1952. Bushing 1952 is similar to bushing 1906, discussed above, but includes a capped structure. As shown in FIG. 19, bushing 1952 includes outer feature 1954 and inner feature 1956. As shown, outer feature 1954 includes a spherical structure that is open on one end to access inner feature 1956. Inner feature 1956 includes a recess that receives an end of a cable. Thus, inner feature 1956 does not extend through the entirety of bushing 1952 and forms a pocket for an end of the cable. Therefore, bushing 1952 allows mount 1950 to act as an end of a cable.

[0097] As illustrated in FIGS. 16-19, the disclosed mounts can be composed of multiple components, and certain components can be divided into several separate parts. In one example, mount 1802, 1900, and / or 1950 are anchors that hold a cable in place relative to a net lattice. It is expressively contemplated that any component associated with the mount can be subdivided into any number of separate components to assist the assembly process. In another example, it is expressly contemplated that the mount, in its entirety, and / or any of its associated components, can be made as a single, unified component.

[0098] FIG. 20A is a pictorial view of a net system according to one example. FIG. 20B is a pictorial view of a net system according to one example. FIG. 20A and FIG. 20B include similar components. Similar components are numbered accordingly and FIG. 20A and FIG. 20B are discussed below in unison. Net system 2000 can be included in a playground structure. As shown in FIG. 20A, net system 2000 includes frame 2002, frame 2003, and net rope 2004. Net rope 2004 can include a single, continuous rope. Alternatively, net rope 2004 can include a plurality of ropes. Net rope 2004 can form a net lattice, as shown in FIGS. 20A-20B. In one example, frame 2002 and frame 2003 are similar to or the same as device frame 504, and net rope 2004 is similar to orL31.12-0088the same as net ropes 102, 202, 302, and / or 402 discussed above. Tn one example, frame 2002 and frame 2003 are connected to net rope 2004. Frame 2002 is opposite to frame 2003, and net rope 2004 is shown to extend between the opposing frames. In one example, frame 2002 and frame 2003 are similar or the same. For purposes of conciseness, a connection between net rope 2004 and frame 2002 will be described in detail however, it is expressly contemplated that the same or a similar connection can apply between net rope 2004 and frame 2003.

[0099] Frame 2002 includes recess 2006. FIG. 20B more clearly illustrates how recess 2006 can be a channel or groove that receives net rope 2004. In one example, frame 2002 contains a channel running in a longitudinal direction parallel to a length of frame 2002. Net rope 2004 is secured within this channel by fasteners, such as clamps, clips, screws, bolts, and / or other fasteners. Alternatively, net rope 2004 can also be looped through eyelets or hooks attached to the inner side of the channel. Additional securing methods can include using built-in anchor points within the channel. In one example, an additional component is used within recess 2006 of frame 2002 to secure net rope 2004 in place.

[0100] In one example, a playground assembly includes frame 2002 component having recess 2006 (i.e. an elongated channel) formed therein. The playground assembly can include net system 2000 formed at least in part by net rope 2004 and one or more net clips (described in more detail with regard to FIG. 21A-21B). Each of the net clips can engage net rope 2004, of net system 2000, when net system 2000 is secured to frame 2002. The engagement formed between each net clip and net rope 2004 is substantially concealed within recess 2006 of frame 2002, such that the net clips and the engaged portions of the net rope are not externally exposed when net lattice 2000 is secured to frame 2002. In some examples, net rope 2004 forming net lattice 2000 is a single, continuous net rope. In some examples, in which net rope 2004 is a single net rope, the engagement between each net clip and the portion of the single net rope is configured such that a portion of the single net rope loops around a respective net clip of the plurality of net clips. For example, net rope 2004 of net lattice 2000 can be passed (i.e. looped) around the net clip. Each net clip can include a rope receiving surface configured to support a respective portion of a single net rope. In one example, the rope receiving surface of each net clip is formed as a recess defined in each net clip, the recess being shaped to receive and support the respective portion of the single net rope.L31.1 -0088

[0101] In one example, each net clip can further include an aperture configured to receive a fastener therethrough, and the fastener can engage the respective portion of the single net rope to secure the single net rope relative to the net clip.

[0102] In one example, the aperture of each net clip extends in a direction that is substantially perpendicular to the rope receiving surface of the net clip.

[0103] In one example, the plurality of net clips can support the single net rope such that a first portion of the single net rope is substantially concealed within the elongated frame component, and a second portion of the single net rope is disposed outside of the elongated frame component.

[0104] In some examples, each net clip can support the single net rope in a manner that causes alternating portions of the single net rope to be disposed inside the frame component (i.e. the first portion) and outside the frame component (i.e. the second portion), thereby forming a repeating pattern of concealed and exposed rope segments along the length of frame 2002.

[0105] In some examples, the one or more net clips are slidably received within frame 2002 which allows positional adjustment of the net clips relative to frame 2002 during assembly or installation of net system 2000. In one example, the net clips are slidably received within recess 2006 formed within frame 2002 such that recess 2006 guides and retains the net clips while allowing a sliding movement along a length of frame 2002. In some examples, each net clip is spaced apart from one another along frame 2002, such that the net rope is supported at spaced locations within recess 2002.

[0106] In another example, frame 2002 is an elongated frame component and includes recess 2006 which defines an elongated slot extending along a longitudinal axis of the elongated frame component.

[0107] FIG. 21A is a perspective view of a net clip according to one example. FIG 21B is a perspective view of a net clip according to one example. FIG. 21 A and FIG. 2 IB include similar components. Similar components are numbered accordingly and FIG. 21A and FIG. 21B are discussed below in unison. Net clip 2008 includes first end 2010, second end 2012, passage 2014, and surface(s) 2016. Surface(s) 2016 can illustratively include an external surface of clip 2008. Additionally, the shape of net clip 2008 can vary based on, in one example, a shape of a recess of a frame. Net clip 2008 also includes passage 2014. Passage 2014 extends through net clip 2008. Passage 2014 can receive net rope 2004, such that net rope 2004 extends through net clip 2008. In another example, passage 2014 can receive a fastener to secure net clip in place (e.g., on aL31.12-0088playground frame). Net clip 2008 can also include channel 2015 which can receive a net rope. Channel 2015 forms a rope receiving surface of net clip 2008. Alternatively to passage 2014, channel 2015 can receive the net rope. The net rope can extend along and / or through channel 2015 (shown and described in more detail with regard to FIG. 24). In one example, the net rope can be looped around net clip 2008 with channel 2015. For example, the net rope can be threaded through and held in channel 2015 such that the net rope loops around net clip 2008. In one example, channel 2015 extends in a direction substantially perpendicular to passage 2014.

[0108] In one example, with reference to FIGS. 20A-20B, net clip 2008 can be made to fit within recess 2006 of frame 2002 and secure net rope 2004 in place. Net clip 2008 can slide within frame 2002 to a desired position along the length of frame 2002. In one example, net system 2000 can include frame 2002 and frame 2003 (as shown in FIG. 20A). In this example, a distance is defined between frame 2002 and frame 2003, and net rope 2004 can span this distance. In one example, during assembly of a net system, net rope 2004 is attached to net clip 2008. Net rope 2004 can be passed through passage 2014 to attach net rope 2004 to net clip 2008. Net clip 2008 can then be disposed within an end of frame 2002, such that net rope 2004 extends out of frame 2002, across the space. In another example, net rope 2004 can be looped around channel 2015 and be thus looped around net clip 2008. Net rope 2004 can be used as a guide to pass net clip 2008 lengthwise through frame 2002. As discussed, net clip 2008 can act as an anchor for net rope 2004 along frame 2002. Net clip 2008 can be secured at a position along frame 2002 by a tension force from net rope 2004, as net rope 2004 is pulled taught across the distance. In one example, a plurality of net clips 2008 can be used and can be spaced apart across a length of frame 2002.

[0109] FIG. 22A is a perspective view of a frame component according to one example. FIG. 22B is a different perspective view of the frame component according to one example. FIG.22A and FIG. 22B include similar components. Similar components are numbered accordingly and FIG. 22A and FIG. 22B are discussed below in unison. FIGS. 22A and 22B include frame 2020 which includes body 2022, recess 2024, and passage 2026. In one example, frame 2020 is similar to or the same as frame 2002 or frame 2003 as discussed above.

[0110] As shown in FIGS 22A and 22B, frame 2020 has a cylindrical shape. It is understood that frame 2020 can include any shape. In one example, frame 2020 can be made from metallic material. Frame 2020 can be made from an extrusion manufacturing process to create a continuous frame portion having a uniform cross-section. As shown, frame 2020 includes a single, continuousL31.1 -0088perimeter having multiple contours. In one example, frame 2020 is made with a pipe profile and the extrusion process involves shaping the pipe into a hollow, cylindrical form as it passes through a specially designed die.

[0111] Frame 2020 includes recess 2024 and passage 2026. In one example, recess 2024 includes a larger opening than passage 2026, relative to frame 2020. Passage 2026 provides a passage from an external environment into an interior space of recess 2024. As shown in FIGS.22A and 22B, the continuous perimeter of frame 2020 can form recess 2024, such that recess 2024 shares the same side as external side 2035 (e.g., external sidewall) of body 2022. Recess 2024 can receive a net clip, such as net clip 2008. Accordingly, the profile of a net clip (e.g., net clip 2008) can match the profile of recess 2024. In one example, a net clip (e.g., net clip 2008) can be inserted through an end of frame 2020 and moved along a length of frame 2020 to a desired location. A fastener can then be inserted near passage 2026 and be driven into area 2030 (e.g., an indent) to secure a net clip in place at a desired location along frame 2020 (shown and described in more detail with regard to FIG. 24).

[0112] Frame 2020 can also include one or more cavities 2032, 2034, and 2036. Each cavity 2032, 2034, and 2036 can form at least one respective internal sidewall of frame 2020. For example, cavity 2034 includes internal sidewall 2037, and so on. In one example, each internal sidewall (e.g., internal sidewall 2037) is separated by external sidewall 2035 by wall 2039 of frame 2020.

[0113] In some examples, cavities 2032, 2034, and 2036 are formed as part of an extrusion process; however, other manufacturing methods may be used to produce similar features, cavities 2032, 2034, and 2036 can have the shapes illustrated in FIGS. 22A-22B, although the number, size, shape, orientation, and arrangement of such cavities can vary according to design considerations. The inclusion of cavities 2032, 2034, and 2036 can reduce the overall weight of frame 2020, decrease material usage, etc.

[0114] FIG. 23 is a perspective view of an elongated frame structure according to one example. FIG. 23 shows that frame structure 2019 can be made for a specific curved frame design. For example, frame 2019 can be made (e.g., extrusion process, etc.) for a specific net system design. Frame 2019 can support a net system, such as net system 2000 shown in FIG. 20A. By way of example, frame 2019 includes several frame pieces; first frame 2020, second frame 2038 and third frame 2040. First frame 2020 is also shown and described in FIGS. 22 A and 22B, andL31.1 -0088FIG. 23 illustrates how frame 2020 can be apart of an overall frame structure (i.e. frame structure 2019). Frame 2020 can be connected to other frame components (i.e. second frame 2038) shown by joint 2028. Frame 2020 can be a straight section, a curved section, or other section. As shown in FIG. 23, each frame section can be connected regardless of the curvature or length of each section, since the end profile of each frame section is compatible. For example, as shown in FIG.23, frame 2020 is connected to second frame 2038, and second frame 2038 is connected to third frame 2040. For example, first frame 2020 is a straight section while second frame 2038 is a curved section, however the end profiles of each section mate at joint 2028. Connecting frame sections together can achieve an overall frame shape of frame 2019. Each frame section can include the same extruded profile, such that recess 2024 and passage 2026 of frame 2020 align with the recess and passage of second frame 2038 and / or third frame 2040.

[0115] Once an overall frame structure 2019 is constructed, one or more net clips can be attached to a portion of net rope prior to being attached to frame 2020, 2038, and / or 2040. In one example, the net clips can then be inserted into recess 2024 of frame 2020. The net rope can be used to pull the net clips through frame 2020 until a desired position along frame structure 2019 for the net clip is reached. For example, a net clip can be inserted in recess 2024 of frame 2020 and passed along the length of each frame section to reach a desired position, such as a position along third frame 2040. This illustratively completes one anchor point for connecting a net system to a frame.

[0116] Returning briefly to FIGS. 20A-20B, net system 2000 is shown as being connected to two opposing frames (i.e. frame 2002 and frame 2003) separated by a distance. One or more net clips can be positioned within frame 2002 and / or frame 2003. along the length of frame 2002 and / or frame 2003 (e.g., see FIG. 20B), to form anchor points for net rope 2004. For instance, a first net clip can be positioned where net rope 2004 enters recess 2006 of frame 2002 and a second net clip can be positioned at a halfway point along frame 2002. Frame 2003 can include net clips in corresponding locations. In one example of an assembly process, net rope 2004 is a single rope and is looped around the first net clip positioned in frame 2002, rope 2004 then exits recess 2006 frame 2002 to extend across to frame 2003, loops around a second net clip positioned within frame 2003, exits frame 2003, and extends back across to frame 2002. This process can be repeated to form net system 2000. Therefore, in one example, a net lattice including net rope 2004 can only include two rope ends (i.e. a start of the rope and the end of the rope). As would be appreciated byL31.1 -0088one skilled in the art, an installer is only required to secure two terminal rope ends when installing the net system.

[0117] FIG. 24 is a perspective view of a net clip attached to a frame component according to one example. Net system 2100 includes frame 2102, net clip 2104, net rope 2106, and fastener 2108. As shown, net clip 2104 can be inserted into recess 2103 of frame 2102. Net clip 2104 can be similar to or the same as net clip 2008. Net clip 2104 secures net rope 2106 along frame 2102. Net rope 2106 can be used to slide net clip 2104 within recess 2103 of frame 2101, and position net clip 2104 at a desired location along frame 2102. A plurality of net clips can be threaded along net rope 2106 and inserted into recess 2103 of frame 2102 (e.g., to form net system 2000 of FIG.20A).

[0118] Net clip 2104 can also receive fastener 2108. Once net clip 2104 is in a desired position along frame 2102, fastener 2108 can pass through net clip 2104 and clamp onto net rope 2106, such that net rope 2106 is clamped against frame 2102. Thus, net rope 2106 can be clamped (i.e. secured) in position. Additionally, fastener 2108 can cause net clip 2104 to deform, such that the ends of net clip 2104 (i.e. similar to or the same as ends 2010, 2012 of net clip 2008) are pressed against the internal sides of recess 2103 of frame 2102. Thus, net clip 2104 can be secured in position. Therefore, fastener 2108 can act in several ways to secure the components to frame 2102. For example, fastener 2108 can cause net clip 2104 and net rope 2106 to be secured simultaneously. In other examples, fastener 2108 can be deployed such that net rope 2106 is secured while net clip 2104 can still be slightly adjusted. However, it is expressly contemplated that other ways of securing net clip 2104 and net rope 2106 can be utilized.

[0119] As shown in FIG. 24, net rope 2106 and fastener 2108 can enter recess 2103 of frame 2102 through passage 2105. Passage 2105 can include an edge that connects recess 2103 to the exterior side of frame 2102. Passage 2105 and / or recess 2103 can form an elongated channel through frame 2102. Net rope 2106 can enter and exit frame 2102 through passage 2105 to extend between frame components. In one example, a first portion of net rope 2106 enters into recess 2103, is looped around clip 2104, and exits recess 2103 to extend to a separate frame component. Fastener 2108 can be inserted into passage 2105 to secure net clip 2104 and / or net rope 2106 in position along frame 2102.

[0120] Frame 2102 can also include bores 2110. Bores 2110 can be used to secure frame 2102 additional frame pieces and / or to other components. For example, bore 2110 can be aL31.12-0088threaded aperture to receive a fastener to connect frame 2102 to a second frame. Bores 2110 can be formed by an extrusion process during the extrusion of frame 2102, or can be added postextrusion. It is understood that bores 2110 can include more or fewer bores than shown in FIG. 24, and can include a variety of sizes, shapes, profiles, etc.

[0121] FIG. 24 also shows an installation operation to construct a playground assembly. In one example, a method of assembling a playground structure includes providing frame 2102 having recess 2103 formed therein. The method can include providing a net lattice (e.g., formed by rope 2106) that includes a first loop and a second loop formed therein. The method can further include placing a first net clip (i.e. clip 2104) in the first loop of the net and sliding, with the first net clip placed in the first loop, the first net clip into frame 2102 such that a portion of net lattice 2106 proximate to the first net clip protrudes from recess 2103. The method can further include placing a second net clip (not illustratively shown) in the second loop and sliding, with the second net clip placed in the second loop, the second net clip into frame 2102 adjacent to the first net clip. In one example, sliding the second net clip into frame 2102 adjacent to the first net clip includes sliding the second net clip into frame 2102 such that a second portion of net lattice 2106 proximate to the second net clip protrudes from the elongated channel (shown in more detail in FIG. 20B).

[0122] In one example, providing the net lattice that includes the first loop and the second loop formed therein includes providing the net lattice formed by a single net rope, and the single net rope defines the first loop and the second loop. In other words, a user can create each net loop by taking a first portion and a second portion of the net rope and forming a “U” shape between the first and second portions such that the first and second portions run substantially parallel. An example of a net loop is shown in FIGS. 20A-20B.

[0123] In one example, sliding the first net clip into the frame component includes sliding the first net clip into recess 2103 along a length of recess 2103.

[0124] In one example, sliding the second net clip into the frame component adjacent to the first net clip includes sliding the second net clip into recess 2103 along the length of recess 2103, and positioning the second net clip adjacent to the first net clip within recess 2103.
