![]() Such tow tab may therefore provide for a quick connection and disconnection of a towing string (not shown). According to an embodiment of the present disclosure, the tow tab 37 provides the only tethering connection to the box kite. 1B), the tow tab 37 is independent of the frame of the box kite. By virtue of being sewn on to the sail 21, therefore part of the canopy ( 30 of FIG. a top sail 21) is a fabric loop defining a tow tab 37 of the box kite according to the present disclosure. 1A, sewn on to one corner of one of the sails 21 (e.g. 1D) receiving the opposite ends of respective spreader struts 25, capped with plugs 44, which serve to hold opposed spars 23 in spaced apart relationship. 1D) received in friction or interference fit relationship over respective spar extensions 26 of the spars 23, and are formed with barrels 42 (e.g. ![]() Sockets, generally designated 41, are formed at one extremity with rings 43 (e.g. The spar extensions 26 are conveniently received at their opposite ends in fabric pockets 27 formed at distal ends of the inside corners of the sails 21, and project medially through fabric sleeves 31 connecting between the opposed sails (top and bottom sails 21). drum-tight) sail fabric which results in a box-like (quadrangular) shape of the sails 21. 1A, the box kite of the present invention includes, generally, a plurality of elongated spars 23, spaced about in a quadrangular pattern with the distal spar extensions 26 thereof received in respective inside corners of sails 21 and pushed apart to provide, in combination, rigidity for the sails 21 and tight (e.g. 1A is a perspective view of a box kite according to an embodiment of the present invention in an assembled state of the box kite. Accordingly, preparation of the struts may include a single step of cutting to a desired length without further processing.įIG. Capping of the extremities of the respective struts with the plugs can provide not only ease of assembly and disassembly of the box kite, but also added safety in the handling of the struts which may include (unfinished) sharp and/or irregular extremities. The extremities of the respective struts may be capped with closed hollow cylindrical plugs with end walls configured to be in coaxial relationship with the respective projecting barrels of the sockets. The sockets are formed on respective one ends with rings that are slid over the spar extensions and configured with respective projecting barrels having bores which receive the extremities of respective struts in friction or interference fit to provide for convenient and effective construction of the box kite. In the assembled state of the box kite of the present invention, the plurality of spars are spaced apart and coextensive, formed at their opposite extremities with spar extensions arranged in respective corners of the quadrangular (e.g. D05B23/00- Sewing apparatus or machines not otherwise provided for.B64C31/00- Aircraft intended to be sustained without power plant Powered hang-glider-type aircraft Microlight-type aircraft.Google has not performed a legal analysis and makes no representation as to the accuracy of the date listed.)
