Collapsible Kite Frame and Method of Collapsing a Kite for Shipping and Storage

Abstract

Disclosed is a collapsible kite frame that permits at kite to be fit into an economical shipping box, thereby significantly decreasing the costs associated with shipping. The kite frame utilizes a double revolute joint to connect the support members of a kite frame. A support sheath locks the joint and support members in a straight alignment, but, when removed, the support members are free to rotate and move inward, towards each other, thereby shortening the combined length span of the support members when in a straight alignment.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

[0031] Disclosed is a method of deconstructing a kite such that the folded kite may fit into an economical shipping box measuring about 8 inches by 18 inches.

[0032] As shown in FIG. 1, the double revolute joint 1000 comprises a first support member 2000, a central link 5000, a second support member 3000, and a support sheath 4000. The support sheath 4000 features a through tunneled opening, allowing the support sheath 4000 to fully encompass the double revolute joint 1000. The support sheath 4000 may be locked into place covering the double revolute joint by connecting a locking tab 3100 on the second support member 3000 to the lock opening 4100 on the support sheath 4000.

[0033] FIG. 2 shows an exploded view of the double revolute joint 1000. As shown, the first support member 2000 features a first support member connection tab 2100 with first support member lateral connection columns 2200 that protrude outward from the connection tab 2100. Similarly, the second support member 3000 features a second support member connection tab 3100 with second support member lateral connection columns 3200 that protrude outward from the connection tab 3100. The central link 5000 features lateral prongs 5100 that extend outward on both ends of the central link 5000, resembling an H shape. The lateral prongs 5100 create channeled openings (insertion hubs 5300, 5400) through which the connection tabs of the first and second support members (2100, 3100) are inserted.

[0034] As shown, the central link 5000 features lateral prongs 5100 which protrude from the center of the central link 5000. The protrusion of the lateral prongs 5100 creates two channels (insertion hubs 5300, 5400) through which the connection tabs of the first and second support members (2100, 3100) are inserted. The lateral prongs 5100 further feature side openings 5200, through which the lateral connection columns of the first and second support members (2200, 3200) are inserted, thereby securing the first and second support members (2000, 3000) to the central link 5000. The first support member connection tab 2100 is inserted into the first insertion hub 5300 such that the first support member lateral connection columns 2200 pass through the side openings 5200 of the lateral prongs 5100, thereby preventing the first support member 2000 from disconnecting from the central link 5000, yet simultaneously allowing a rotational movement. Likewise, the second support member connection tab 3100 is inserted into the second insertion hub 5400 such that the second support member lateral connection columns 3200 pass through the side openings 5200 of the lateral prongs 5100, thereby preventing the second support member 3000 from disconnecting from the central link 5000, yet simultaneously allowing a rotational movement.

[0035] FIG. 3 shows an environmental view of the double revolute joint 1000 locked in a straight alignment by sliding the support sheath 4000 over the central link 5000 and the connection tabs of the first and second support members (2100, 3100). Locking the support sheath 4000 over the double revolute joint 1000 creates a rigid frame construction, permitting the kite to withstand the forces of stretched fabric across the frame. The construction disclosed herein results in a superior construction and strength of kites having large dimensions with the additional ease of compact and inexpensive shipping in relatively small containers.

[0036] FIGS. 4 and 5 show the double revolute joint 1000 in use. As shown in FIG. 4, the connection between the insertion hubs (5300, 5400) (shown in FIG. 2) of the central link 5000 and the connection columns of the first and second support members (2200, 3200) (shown in FIG. 2) permits the first and second support members (2000, 3000) to rotate with respect to the central link 5000. The corresponding circular shapes of the first and second support member lateral connection columns (2200, 3200) (shown in FIG. 2) and encompassing side openings 5200 of the lateral prongs 5100 permit the first and second support member lateral connection columns (2200, 3200) (shown in FIG. 2) to rotate within the side openings 5200. This rotation motion allows the first and second support members (2000, 3000) to move inward, towards each other, such that the support members (2000, 3000) overlap, and thereby shorten the length span of the first and second support members (2000, 3000) together without disconnecting the first and second support members (2000, 3000).

[0037] FIGS. 5 and 6 show the double revolute joint 1000 being straightened and secured with the support sheath 4000. As shown in FIG. 5, the support sheath 4000 encompasses the first support member 2000 when not in use. When the support sheath 4000 is not in use, the first and second support members (2000, 3000) are able to rotate with respect to the central link 5000 via the revolution of the first and second support member lateral connection columns (2200, 3200) (shown in FIG. 2) within the side openings 5200. FIG. 6 shows the support sheath 4000 when in use to support the double revolute joint 1000. The support sheath 4000 slides laterally along the first support member 2000 towards the double revolute joint 1000 such that it encompasses the entirety of the central link 5000 and covers the first and second support member connection tabs (2100, 3100) (shown in FIG. 2) connected to the first and second insertion hubs (5300, 5400) (shown in FIG. 2) of the central link 5000. The rigidity of the support sheath 4000 acts to prevent the rotation of the first and second support member lateral connection columns (2200, 3200) (shown in FIG. 2) within the side openings 5200 of the lateral prongs 5100 of the central link 5000, thereby locking the first and second support members (2000, 3000) in a straight alignment.

[0038] Still referring to FIG. 6, the support sheath 4000 features a lock opening 4100 which corresponds in the shape to the locking tab 3300 of the second support member 3000. The support sheath 4000 slides laterally along the first support member 2000, over the central link 5000, and connects to the second support member 3000 via lock opening 4100 which encompasses the locking tab 3300 of the second support member 3000. As shown, when the lock opening 4100 is connected to the locking tab 3300, the support sheath 4000 encompasses the central link 5000, and the first and second support member connection tabs (2100, 3100) (shown in FIG. 2) of the first and second support members (2000, 3000).

[0039] FIG. 7 shows a common shipping box 6000 measuring 18 inches (length) by 8 inches (width) by 1.5 inches (height) and a standard kite. The kite depicted in FIG. 7 is not limiting as to the variation in dimensions and style of the kites that may be collapsed and contained within the common shipping box referenced. Kites with wing spans ranging from 4.7 inches to 93 inches and heights ranging from 3.1 inches to 305 inches may be collapsed with the use of double revolute joints to fit within the common shipping box referenced above. Referring back to FIGS. 4 and 5, when folding the kite, a person will slide the support sheath 4000 away from the central link 5000, toward the first support member 2000, such that the first and second support members (2000, 3000) are each free to rotate with respect to the central link 5000. The rotation of the first and second support member (2000, 3000) results in a shortening of the span of the support members, permitting a kite of larger portions to be folded and fit within the economical shipping box 6000 shown of FIG. 7. Referring still to FIGS. 4 and 5, when removing the kite from the shipping box 6000, a user may align the first and second support members (2000, 3000), slide the support sheath 4000 over the central link 5000, and connect the locking tab 3300 with the lock opening 4100, thereby securing the first and second support members (2000, 3000) in a rigid line. Once the first and second support members (2,000, 3,000) are secured in a rigid line, the material of the kite will be stretched out and ready for flight.
