If one is facing high density storage of telescopic tubes for tote sake, then keeping the tubes free from projective collars, pins, interior structures, etc. that prevent 100% concentric nesting without adding length buildup, then there comes probably the challenge of protective the open ends of the tubes during any handling, transporting and even during assembly or disassembly. Care tactics might include placing temporary end-tube cushion socks or special temporary plugs upon de-telescoping or separating of tubes from the nest.

When using a Joe Cup coupler, a rounding plug in the child tube's insertion end might be used; and if non-laterally projecting, then such plug for just one end of tubes might be permanent, leaving the other end open; but note this challenges the 100% target, but a tiny compromise might be globally beneficial. Still seek a means for the 100% deal where the end plug might be temporary, not permanent.

In tote, a telescopic nest where tubes have no holes or plugs presents inadvertent spillage, so a means is needed to firmly cap both ends of the nest; two caps cabled together might work where one cap is placed and then the other cap, but the caps are kited together.

Efficient Storage and Protection of Telescopic Tubes for TPHG

When aiming for high-density storage of telescopic tubes, particularly for the ease of transport in a compact tote, it's essential to avoid any structures that interfere with full concentric nesting without adding to the overall length of the nest. Elements like collars, pins, or interior mechanisms that project into the structure can cause unwanted length buildup, which compromises the compactness necessary for urban transport.

However, with the tubes free of such protrusions, protecting the open ends during handling, transport, and even assembly or disassembly becomes crucial. A possible solution involves using temporary end-tube cushions or specialized plugs. These would be applied upon de-telescoping or when separating the tubes from the nest to safeguard the ends.

For designs utilizing a Joe Cup coupler, consider placing a rounding plug in the insertion end of the child tube. If the plug does not project laterally, it could potentially be permanent, leaving the opposite end open. While this introduces a slight compromise in maintaining 100% avoidance of length increase, such a minimal trade-off could be beneficial in the broader design. However, a better solution might involve temporary, rather than permanent, plugs to maintain the goal of full nesting without lengthening.

To prevent inadvertent spillage of tubes during transport, consider firmly capping both ends of the nested set. A practical approach could involve using two end caps connected by a cable, which keeps the caps "kited" together. One cap would be applied first, followed by the second, ensuring the nest is securely enclosed and the caps remain tethered and on the tube set ends; such stops spillage.

Protecting Telescopic Tube Ends During Unpacking

During unpacking of tubes, perhaps have ready rubber plugs to protect the open ends of the tubes.

To safeguard the open ends of telescopic tubes during unpacking and handling, it's practical to use rubber plugs. These plugs can prevent damage or contamination of the tube ends and ensure they remain in good condition for assembly.

When inserting a child tube into a Joe Cup for insertion in the mother tube, be sure that the plug has the same OD as the OD of the child; the Joe Cup body material will wrap around the plug's side, so there should be a distinct non-cutting radius to the plug's exterior edge.

From an engineering perspective, using rubber plugs provides several advantages:

• Protection: Plugs prevent debris and dirt from entering the tubes, which could affect the functionality and performance of the telescopic mechanism.
• Damage Prevention: They shield the tube ends from potential impacts or scratches that could compromise the integrity of the tubes.
• Ease of Handling: Rubber plugs make handling easier by covering sharp edges, reducing the risk of injury or snagging.

Ensure that the plugs are of appropriate size and material to fit snugly within the tube ends without causing deformation. Regular inspection and maintenance of these plugs will also help in extending their useful life.

==================================

a meta spar will use three or four sizes of spar segments requiring two or three sizes of Joe Cups to make the joins that make up the meta spars.

Response:

Here are some additional thoughts:

• Design Versatility: Using multiple sizes of Joe Cups means you can create a highly adaptable structure that can handle different wing configurations and experimental setups.
• Connection Strength: Ensuring that the joins between the different sizes of spar segments and Joe Cups maintain structural integrity will be essential for safety and performance.
• Ease of Assembly: Consider how intuitive the assembly will be for users. Having clear instructions or diagrams can help facilitate a smooth setup process.
• Weight Distribution: The varying sizes will also allow for better weight distribution along the wing, which can positively affect handling and stability during flight.
• Testing Variations: Once you have your Joe Cups and segments ready, testing different configurations will be key. You might discover optimal arrangements that enhance performance.

This thoughtful design strategy should lead to exciting results for your TPHG. How do you envision the process of creating and testing these configurations?

Joe Cup Coupler Realization for Meta Spar of Three Spar Segments Maybe Useful for Kingpost and Queenposts[/b]

In a meta spar consisting of three spar segments, the design uses a stepwise double-tapered configuration. The central segment serves as the mother tube, while two outer segments—called child tubes—insert into the ends of the mother tube. This assembly employs two Joe Cup couplers, but with an important twist: one Joe Cup faces one direction, while the other faces the opposite way. This configuration is particularly useful for maintaining structural integrity and resisting axial loads in applications like kiting and hang gliding.

A good example of this arrangement is the crossbar in a Malay kite, where the double-taper stepwise design utilizes a central tube with two end sticks joined via oppositely facing Joe Cup couplers. In a Tiny Packed Hang Glider (TPHG), this three-part configuration can be applied to the kingpost and two queen posts.

Resistance to Buckling:
The tapered design, with the mother tube as the central strong section and the two child tubes tapering outward, gives the system a significant advantage in resisting compressive buckling. The thicker central segment provides stability where it's most needed, while the tapered outer segments help reduce overall weight without sacrificing structural integrity.

Axial Compression and Rigging:
In both kiting and TPHG, rigging plays a critical role in maintaining axial compression along the meta spars. The tension exerted by the sail keeps the spars under compression, allowing the structure to remain stable without the need for additional locking mechanisms. The use of oppositely facing Joe Cups ensures that each child tube locks securely into the mother tube, preventing misalignment and further supporting the axial compression.

Application in TPHG:
In the case of the kingpost, the three-part arrangement consists of a central mother tube, with two planetary child tubes forming the outer segments. Each queen post follows a similar design, where each post is a separate meta spar made up of a mother tube and two child tubes. The Joe Cup couplers provide a simple, lightweight way to assemble each spar segment, while the sail tension and rigging keeps everything in axial compression during flight. The resistance to buckling and ease of assembly make this an efficient solution for compact, portable glider designs.

TPHGs: the new dandelion radiance for the world.

In the case of dandelion seeds, the parachute-like structure creates vortex rings around the seed as it falls, forming a low-pressure "air pocket." This pocket helps slow the descent of the seed, allowing it to float farther. These vortex structures and pockets are critical to the seed's aerodynamic dispersal.

Advanced Development: Joe Cup Body Strap and Collar Integration

Another advancement has been discovered and proven: The Joe Cup's body strap can be multiply wrapped and bonded to the cylindrical segment collar, while still being able to feed into the insertion space inside the mother tube by coming off the outside of the collar. This innovation allows the strap to work more effectively under axial compression between the mother and child tubes.

Key Benefits of Multiple Wrapping:

The strap, when multiply wrapped and bonded, will allow for spot filling on the collar, ensuring the mother tube is hugged snugly around its entire circumference.
This design reinforces the collar and strap interface, creating a non-sewing firm fold that reliably limits the insertion of the child tube during axial compression in flight.
The multiple wrapping adds structural integrity to the entire assembly, preventing unwanted slippage or movement.

This technique enhances the overall performance and durability of the Joe Cup assembly, particularly in managing the forces between the mother and child tubes during compression. It provides a robust and low-cost method of ensuring tight integration.

As usual, the body strap filling the gap between mother and child may be thickened as needed. Also, the child insertion end will have a plug to stabilize the child's open end and provide a softening radius to prevent the child's tube end from cutting the Joe Cup strap. Also, an additional bushing could be used to work with a Joe Cup when needed to fill the mother-child gap.

Hi Doug,

I enjoy most of your posts, but your most recent (above) seems to be stretching Joe's 5 foot topic just a bit.

[dhmartens]

You are correct Bob. The 5 foot hang glider movement is part of FAA part 103, the Poo Fighter telescopic glider is part of both Faa part 103 and Faa part 107 and it does seem a bit of a stretch. I am looking into the licensing and requirements of a dual purpose invention. It really comes down to funding where more customers can provide better chances of long term success.
