DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0029] The description that follows is presented to enable one skilled in the art to make and use the present invention, and is provided in the context of a particular application and its requirements. Various modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principals discussed below may be applied to other embodiments and applications without departing from the scope and spirit of the invention. Therefore, the invention is not intended to be limited to the embodiments disclosed, but the invention is to be given the largest possible scope which is consistent with the principals and features described herein.

[0030] FIG. 2 is an exploded isometric view of the butterfly handle locking device 100 of the present invention. An embodiment of the sportsboard and sportscraft locking device 100 of the present invention has two main body portions 102 that fit together. Each main body portion 102 has a central region 104 with an axial bore 106. A flange 108 having a shackle bore 110 extends from the central region 104 of each main body portion 102 in a plane perpendicular to the central axis A, with the flange 108 on a first main body portion 102 immediately adjacent the flange 108 on a second main body portion 102. A wing arm structure 112 extends from the central axis A of each main body portion 102.

[0031] The two main body portions 102 are secured together in axial alignment by an axle 120. The axle 120 could be a bolt 120 with a head 122 at one end and screw threads 124 at the other end, and a nut 126. In addition, the axle 120 could also be a lock or jam pin that fits securely at the ends but allows rotation of the two main body portions 102. Thus, the entire device 100 is a unitary assembly. The butterfly handle locking device 100 can be formed using any suitable, rigid material such as, but not limited to, regular and hardened metal, hardened steel, stainless steel, polymeric material including plastic and rubber, fiberglass, resin-based material, composite and injection-molding substrate, etc.

[0032] FIGS. 3A-3C are isometric views of the butterfly handle locking device of the present invention in the unlocked, intermediate and locked positions, respectively. When the flanges 108 on the main body portions 102 are pivoted such that the flanges 108 are away from each other, the wing arms 112 of the two main body portions 102 pivot closer together as best shown in FIG. 3A. This would commonly be referred to as an unlocked position because the wing arms 112 are folded together and unable to be secured between the handle lobes 86 of the butterfly handle 90. However, when the flanges 108 are pivoted together they pass through an intermediate position as best shown in FIG. 3B. As the flanges 108 continue to pivot together so that they overlap and the shackle bores 110 line up, the wing arms 112 pivot away from each other into a fully spread open position as best shown in FIG. 3C. In this fully spread open position the wing arms would be locked inside the interior space 94 and unable to pass through the gap B between the two lobe handles 86 of the butterfly handle 90.

[0033] FIGS. 4A-4C are section views of the butterfly handle locking device of the present invention in the unlocked position adjacent a typical butterfly handle, in an intermediate position disposed partially within a typical butterfly handle, and in the locked position installed in a typical butterfly handle. The three positions of the butterfly handle locking device 100 shown in FIGS. 4A-4C are essentially equivalent to and correspond directly with those shown in FIGS. 3A-3C.

[0034] As described above, when the flanges 108 on the butterfly handle locking device 100 are separated, the wing arms 112 swing together and the lower portion of the device 100 can be inserted through the opening B of the handle 90, as best shown in FIG. 4A. As the flanges 108 are pivoted together, they begin to overlap. In addition, in the intermediate position as best shown in FIG. 4B, the wing arms 112 begin to spread apart and occupy the interior space 94 of the handle 90. Finally, once the flanges 108 are pivoted together so that they completely overlap, the shackle bores 110 align and the wing arms 112 assume a fully spread open position. In this locked position, the butterfly handle locking device 100 is secured to the handle 90 and the wing arms 112 are spread too far open to be able to pass back through the opening B between the handle lobes 86.

[0035] FIGS. 5A-B are isometric views of the butterfly handle locking device 100 of the present invention in the locked position installed in a typical butterfly handle 90 mounted on a sportsboard or sportscraft 80 without padlock 70 and cable 72 and with padlock 70 and cable 72, respectively. It will be understood that once the flanges 108 of the two main body portions 102 line up flush with each other and the shackle bores 110 in the two flanges 108 align as shown in FIGS. 3C and 4C, the butterfly handle locking device 100 is in a locked position. The shackle arm 74 of a padlock 70 can pass through both of the shackle bores 110 and also pass through the spliced eyelet end 76 of the cable 72 before closing.

[0036] It will be understood that various padlocks 70, cable 72, chains and other flexible connectors and locking devices may be used as desired for securing the two flanges 108 of the main body portions 102 and preventing them from separating. Thus, the sportsboard or sportscraft 80 can be locked with a padlock 70 and cable 72 or chain to essentially anything, for example a roof-top or rear rack or carrier, inside a truck or other vehicle, to a larger boat, or to any other object as desired. It will also be understood that butterfly handles 90 of various shapes and sizes are used commonly on a range of products from sportsboards and sportscraft to large shipping boxes, packaging for electronic appliances, and on home appliances as well as commercial equipment.

[0037] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. Although any methods and materials similar or equivalent to those described can be used in the practice or testing of the present invention, the preferred methods and materials are now described. All publications and patent documents referenced in the present invention are incorporated herein by reference.

[0038] While the principles of the invention have been made clear in illustrative embodiments, there will be immediately obvious to those skilled in the art many modifications of structure, arrangement, proportions, the elements, materials, and components used in the practice of the invention, and otherwise, which are particularly adapted to specific environments and operative requirements without departing from those principles. The appended claims are intended to cover and embrace any and all such modifications, with the limits only of the true purview, spirit and scope of the invention.
