An apparatus for launching a flying disc comprises an elongated handle member, an elongated launching member, a disc gripper, and a release mechanism. The launching member is connected at its proximal end to the distal end of the handle member so as to permit relative angular motion of the launching member and the handle member. The disc gripper is connected to the launching member at its distal end. The release mechanism is operatively coupled to the disc gripper and arranged so as to (i) enable the disc gripper to hold the flying disc with the launching and handle members forming an angle less than a release angle and (ii) cause the disc gripper to release automatically the held flying disc as the launching and handle members move to the release angle from an angle less than the release angle.
A method for launching the flying disc comprises: (i) arranging the launching and handle members to form an angle less than the release angle; (ii) loading the flying disc into the disc gripper; (iii) engaging the release mechanism to engage the disc gripper to hold the flying disc; and (iv) grasping the proximal end of the handle member and swinging the launching apparatus to cause the launching and handle members to move to the release angle and to cause automatically the disc gripper to release the flying disc, thereby launching the flying disc.
Objects and advantages pertaining to launchers for and launching of a flying disc may become apparent upon referring to the exemplary embodiments illustrated in the drawings and disclosed in the following written description and/or claims.
The embodiments shown in the Figures are exemplary, and should not be construed as limiting the scope of the present disclosure and/or appended claims. It should be noted that the drawings depict an exemplary embodiment suitable for use by a right-handed user, however, it is intended that the present disclosure and claims shall encompass both right- and left-handed embodiments, as well as embodiments that can be used with either handedness.
An exemplary embodiment of an apparatus for launching a flying disc is illustrated schematically in
The disc gripper 16 is connected to the distal end of the launching member 14 and can be arranged in any suitable way for gripping the flying disc 900. As illustrated schematically in
In the exemplary embodiment, the disc gripper 16 comprises a pair of opposed gripping members 112 and 114 arranged for gripping the flying disc 900 positioned between them (
In the exemplary embodiment, the release mechanism 18 is operatively coupled to at least one of the opposed gripping members 112 or 114 so as to (i) bias the opposed gripping members 112 and 114 toward one another to hold the flying disc 900 between them with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R) and (ii) release automatically the bias on the gripping members 112 and 114 thereby releasing the held flying disc 900 as the handle member 12 and the launching member 14 move to the release angle (R) from the angle (A) less than the release angle. The release mechanism 18 can be thus coupled in any suitable way. In the exemplary embodiment, the pivotably connected gripping member 114 comprises an elongated distal arm of a lever and is arranged for gripping the flying disc 900. The lever also comprises a proximal lever arm 116 arranged for engaging the release mechanism 18, and is pivotably connected to the launching member 14 at a pivot point 118 between the lever arms 114 and 116.
The proximal lever arm 116 of the exemplary embodiment includes a linear ratchet 120 arranged so as to (i) engage the release mechanism 18 to bias the gripping members 112 and 114 toward one another with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R) and (ii) disengage automatically from the release mechanism 18 and release the bias on the gripping members 112 and 114 as the handle member 12 and the launching member 14 move to the release angle (R) from the angle (A) less than the release angle. In the exemplary embodiment, release mechanism 18 includes a flange 14c on the launching member 14 that is arranged so as to (i) engage the linear ratchet 120 with the handle member 12 and the launching member 14 forming an angle (A) less than the release angle (R) and (ii) disengage automatically from the linear ratchet 120 as the handle member 12 and the launching member 14 move to the release angle (R) from an angle (A) less than the release angle. In an alternative embodiment, such a flange could be positioned on handle member 12 instead (described further below). The proximal lever arm 116 can be arranged to engage or disengage from the release mechanism 18 in any other suitable manner.
In the exemplary embodiment, one of the projections 12a can be arranged to include a cam portion 12c (
In an alternative embodiment (
The angle (A) formed between the handle member 12 and the launching member 14 typically has some minimum angle imposed by the nature of the mechanical joint connecting them. It may be possible to arrange the handle member 12 and launching member 14 so that the minimum angle is anywhere from 0° to 180°, but the minimum angle is typically greater than about 60°, more typically greater than about 90°, and most typically greater than or equal to about 120°. The angle (A) referred to in the present disclosure will typically be greater than the minimum angle and only extend beyond the release angle (R) by a few degrees (perhaps as much as about 10°). The release angle (R) is typically less than or equal to about 180°, and can range between about 150° and about 180° (note that angles greater than 180° indicate that the handle and launching members have moved through and beyond a parallel arrangement). The handle member 12 and the launching member 14 can be arranged so as to limit the relative angular motion to less than a maximum angle, which is at least as large as the release angle (R). In some instances the maximum angle is about equal to the release angle (R); in other instances the maximum angle is greater than the release angle (R).
In the exemplary embodiment, the handle member 12 and the launching member 14 are arranged so as to limit their relative rotation between the minimum and maximum angles. A wedge-shaped depression 14b on the rearward projection 14a of launching member 14 receives a wedge-shaped protrusion 12b on one of the opposed surfaces of forward projections 12a of handle member 12 (
A method for launching the flying disc comprises: (i) arranging the handle member 12 and the launching member 14 to form an angle (A) less than the release angle (R); (ii) loading the flying disc 900 into the disc gripper 16; (iii) engaging the release mechanism 18 to engage the disc gripper 16 to hold the flying disc 900; and (iv) grasping the proximal end of the handle member 12 (with one hand or with both hands, as desired) and swinging the launching apparatus to cause the handle member 12 and the launching member 14 to move to the release angle (R) and to cause automatically the disc gripper 16 to release the flying disc 900, thereby launching the flying disc 900. Typically, the plane of the swing, the plane of the disc, and the plane in which handle member 12 and launching member 14 rotate relative to one another are approximately parallel to one another to result in proper flight of the flying disc. Other arrangements can be employed if suitable or desired. A typical swing is illustrated schematically in
Use of the disc launcher will typically include a backswing after the disc is loaded into the disc gripper. During the backswing, inertia will tend to move the launching member toward or beyond the release angle, causing the disc to be released prematurely. An variety of mechanisms or arrangement can be employed to prevent (or reduce the likelihood of) such a premature release. In the exemplary embodiment illustrated schematically in
The direction of disc flight relative to the swing, the distance traveled by the launched disc, and the character of the disc's flight each depend on the dimensions and arrangement of the disc launcher. Any desired lengths can be chosen for the handle and launching members. The handle member is typically less than about 3 feet long, and often between about 2 feet long and about 3 feet long; the launching member is typically less than about 2 feet long, and often between about 1 foot long and about 2 feet long. A longer handle member 12 can result in longer disc flight, but too long of a handle member impedes swinging of the launcher due to increased weight and air resistance. The relative lengths of the launching member 14 and handle member 12 affect the amount of spin imparted onto the launched disc, which can be optimized empirically for each type of disc, for each user, or for desired disc flight characteristics. Both handle member 12 and launching member 14 can be constructed with telescoping or interchangeable shafts or barrels, to enable adjustments of their lengths to achieve such optimization (
