Rope bridges are known and used in many indoor and outdoor settings for a wide range of uses including seafaring, exploration, theatre, construction, and recreation. Rope may consist of one or more groups of fibers or strands twisted or braided together into a larger form. One or more ropes may be joined or braided together to form a rope bridge. A rope bridge may be suspended above the ground with one or more ends of the rope being secured to one or more abutments. For example, a rope bridge may include a rope suspended above the ground stretched between one or more play structures.
A braided bridge includes a mounting cable. The braided bridge further includes a first spoke component configured to couple to the mounting cable, where the first spoke component includes one or more spokes and a second spoke component configured to couple to the mounting cable. The one or more spokes of the first spoke component are configured to fold and couple the second spoke component to the first spoke component.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used as an aid in determining the scope of the claimed subject matter. The claimed subject matter is not limited to implementations that solved any or all disadvantages noted in the background.
Playground structures require many design considerations. The structures should be safe for users, resilient to user wear, weather resistant, cost effective, easily accessible, resistant to vandalism and theft, and require minimal maintenance.
Given all of the design considerations, playgrounds often include a wide variety of equipment made up of different materials. Braided bridges are one of many pieces of equipment that may be included in a playground. Traditionally, braided bridges are bridges made up of pieces of rope made from natural or synthetic fibers wherein the pieces of rope are joined or braided together and suspended above the ground, whereby the ends of the rope are secured to one or more play structures. Braided bridges are often used in playgrounds for users to walk across, balance on, and/or climb on.
However, it is increasingly desired for braided bridges to be resistant to user wear and be able to withstand weather related elements such as rain, snow, or sun. Therefore, it is desired for braided bridges be constructed such that the bridges are durable, long-lasting, and do not degrade over time.
Rope 110 has several disadvantages such as being susceptible to rot, degradation, mildew, and being vulnerable to vandalism. Additionally, ends 150 of rope 110 may need to be bound with tape, heat shrink tubing, or other material such as twine to prevent fraying or unravelling of the rope. If ends 150 of rope 110 are not properly bound, rope 110 may fray and degrade over time. Further, rope 110 has the tendency to be highly abrasive making it dangerous for users to use without protective outerwear.
Therefore, it is desired to have a solution that is cost-effective, safe, and durable. This would eliminate or reduce the number of times a braided bridge would need to be replaced and prevent injuries during use. In one example, the braided bridge includes a rubber belting material that is suspended above the ground and secured to two play structures.
As shown, spoke components 210 are braided together to form braided bridge 200. For instance, a first spoke component 212 wraps around a second spoke component 214, which wraps around a third spoke component 216, which wraps around a fourth spoke component 218, and so on. In other examples, first spoke component 212 can reach further (e.g. to third spoke component 216 or fourth spoke component 218). In some examples spoke components 210 can be braided to one another in other ways as well. Assembly of braided bridge 200 may be completed on site or may be completed before delivery to the install site.
Spoke components 210 can be formed in a variety of different ways. In one example, spoke components 210 may include a belting material that is water jet cut from a larger belt. In one example, spoke components 210 may be die cut from a belt structure. In other examples, spoke components 210 may be cut or formed in different ways. As shown, braided bridge 200 comprises a belting material. In one example, the belting material comprises rubber. In other examples, the belting material can comprise a material other than rubber. In some examples, the belting material can be re-enforced with materials such as steel, cotton, polyamide, polyester, or aramid fibers such as Kevlar. In other examples, the spoke component belting material may be textured. Additionally, in other examples, the belting material may be perforated for easier bending/folding/braiding of spoke components 210. The perforation may also provide a different experience for the user. For instance, a perforated bridge may be more flexible and/or stretch.
Belting materials, such as rubber, provide several benefits. Rubber material is not only durable, low maintenance, and cost-effective but provides essential slip-resistant properties making it safe for users to climb on, walk on, or hold on to even in the rain. Also, the slip-resistant properties of rubber are maintained over time even through use and wear.
Mounting cables 220 may be used to secure braided bridge 200 to one or more play structures. In one example, mounting cables 220 are attached to a play structure using a clevis connection 230 which attaches to a flange on the play structure. In other examples, mounting cables 220 can be connected to other components in different ways as well.
Mounting cables 220 may be spread to varying lengths. As shown in
At block 810, a first spoke component and a second spoke component are aligned. In one example, aligning the first and second spoke components includes placing the second spoke component directly on top of the first spoke component such that the center mounting apertures of the first and second spoke component align and rotating the second spoke component such that the spokes of the first component do not overlap with the spokes of the second component. In other examples, the alignment of the first and second spoke components may differ.
At block 820, the first spoke component is folded about the second spoke component. In one example, folding the first spoke component includes bending each individual spoke inward towards the center mounting apertures and overlapping each spoke such that all peripheral apertures on the first spoke component align with the center mounting apertures. In another example, the folding process of the first spoke component may differ.
At block 830, mounting cables are inserted through the aligned center mounting apertures of the first and second spoke component and the aligned peripheral apertures of the first spoke component. In one example, the mounting cables may comprise rope or cable. In other examples, the mounting cables may comprise chains or other flexible material. In some examples, the mounting cables are inserted earlier (e.g. before or after blocks 810 or 820).
At block 840, a next spoke component is placed on top of the last folded spoke component. In one example, the center mounting apertures of the next spoke component are inserted onto the mounting cables and the next spoke component is aligned with the last added spoke component such that the spokes of the next spoke component do not overlap with the spokes of the last added component. In other examples, the alignment of the last added and next spoke components may differ.
At block 850, the spokes of the last added spoke component are folded about the next added spoke component. In one example, folding the last added spoke component includes bending each individual spoke inward towards the center mounting apertures and overlapping each spoke such that all peripheral apertures on the last added spoke component align with the center mounting apertures. In another example, the folding process of the last added spoke component may differ.
At block 860, the alignment and folding process of spoke components is repeated until the desired length of the braided bridge is achieved.
At block 870, the braided bridge is mounted to a play structure. In one example, the braided bridge may be mounted to one or more play structures using clevis connections which attach to the flanges on the play structure, as indicated at block 872. In another example, the braided bridge may be mounted independently, as indicated at block 874.
