This invention relates generally to construction of toys, and more particularly to darts for use in playing the game of darts.
Dart tips are generally constructed one of two ways: as a standard pointed-tip dart or as a safety, non-pointed tip darts.
It is well recognized that darts having a pointed tip are generally inappropriate for use by children. Examples of pointed, or sharp, tip darts is provided in U.S. Pat. No. 4,230,322, entitled “No Bounce Dart”, U.S. Pat. No. 6,533,688, entitled “Dart With Rotary Flight And Light Means”, U.S. Pat. No. 5,118,117, entitled “Recreational Dart”, U.S. Pat. No. 6,248,033, entitled “Darts For The Game Of Darts”, and U.S. Pat. No. 4,842,285, entitled “Anti-Bounce-Out Dart”, the disclosure of each of which is incorporated herein by reference.
Examples of a safety, non-pointed tip darts are magnetic tip darts and suction cup tip darts, as described by U.S. Pat. No. 6,267,698, entitled “Soft Tip Game Dart”, and U.S. Pat. No. 5,775,694, entitled “Dart Game With Blunt Dart Having Magnet Surrounded By Non-Magnetic Sleeve And Board Including Magnetic Material”, the disclosure of which is incorporated herein by reference. The '694 patent describes providing a standard dart body with a high-energy magnet at its tip to allow the electromagnetic input that results from the dart striking the dartboard to register the regions of the board that is struck.
To provide a participant in the game of darts with a competitive advantage, numerous efforts have been made to improve the flight of darts and to reduce “bounce-out” after a dart strikes the dartboard. One such technique is described in U.S. Pat. No. 5,642,887, entitled “Game Dart With Retractable Flight Section”, the contents of which are incorporated herein by reference.
Such conventional techniques, however, fail to provide a dart that is safe, that provides acceptable flight characteristics, and that is durable and economical to produce. Accordingly, the dart of the present invention has been developed to provide a dart that is durable, is economical to produce, and provides superior flight characteristics without compromising its essential safe nature.
To overcome the deficiencies of conventional darts, the present invention provides a dart having a lightweight, flexible tail that makes up a majority of the length of the dart, thereby improving safety.
The dart of the present invention includes a flexible tail made from an interwoven mesh to significantly reduce the weight of the tail and to provide the dart with superior flight characteristics. As constructed in the manner described below, the dart can be thrown in a knife-like fashion, i.e. with the thrower grasping the tail rather than the head or body. The dart is self-righting and the unique construction allows the tail to self-correct during flight. In addition to being light in weight, the mesh performs a shock absorbing function to reduce bounce-out.
The present invention provides a dart made by combining a head having first and second ends, with the first end being of a larger diameter than the second end, and the first end includes a magnet; with a flexible tail fixedly and permanently secured to the second end, wherein the flexible tail is formed from a tube of woven material.
The present invention further provides a method of constructing a blunt end safety dart by weaving a fiber to create a flexible tube; by constructing a flexible tail by inwardly folding the flexible tube to create first and second ends, wherein all exposed ends of the fiber are placed at the first end and only a continuous weave appears at the second end. A dart head is constructed by affixing a magnet in a first end thereof and providing a hole in a second, opposite end; and by affixing, in the second end of the head, the first end of the folded flexible tube, wherein the flexible tail makes up a majority of the overall length of the dart.
For a better understanding of the invention as well as other objects and further features thereof, reference is made to the following detailed description to be read in conjunction with the accompanying drawings, wherein:
The following detailed description of preferred embodiments of the invention is made with reference to the accompanying drawings. In describing the invention, explanation of related functions or constructions known in the art is omitted for the sake of clearness in understanding the concept of the invention, to avoid obscuring the description of the invention with unnecessary detail:
In a preferred embodiment, a dart 100 is constructed with a dart head 102 and tail 104. The tail 104 is of a conical, tapered shape formed from a mesh tube to provide a flexible, permanently affixed tail, as shown in
The tail 104 preferably is constructed from a tube of a loosely woven material, such as a nylon mesh. The interlacing strands are weaved or braided in a manner to construct a tube that resembles a Chinese finger trap. To prevent fraying, it is preferable to utilize a coated material. In a preferred embodiment, a nylon mesh is utilized. It will be recognized that other materials can be used.
As shown in
Distal end C has the largest relative diameter, created by allowing the mesh to expand. The expanded mesh has larger gap between the weave, which increases air drag at distal end C and providing a self-righting operation. Such construction eliminates the need for fins, which are necessary on conventional darts.
In a preferred embodiment, the mesh tube is inwardly folded, thereby creating a double thickness of the tube throughout, which advantageously increases the stiffness of the tail 104. The lightweight of the mesh allows the double thickness to be utilized without adding an undesirable amount of excess weight. Utilization of the woven mesh to construct the tail 104 creates a hole in the tail 104, with the hole extending longitudinally from distal end C through middle portion B to proximal end A.
As shown in the close-up views
The dart head 102 is preferably made of rigid plastic or like material, and as also shown in
The invention is not limited to the disclosed preferred embodiment, and should be construed to cover all such alternatives, modifications and equivalents as defined in the appended claims.
