The present invention relates generally to an object launcher, and specifically to a single-handed device for engaging the object with the launcher, and more specifically to forming and throwing a snowball using the same apparatus, and most specifically to single-handedly forming a snowball using an apparatus and thereafter using the apparatus to launch the snowball thereby formed.
The art and practice of molding snowballs is well-known. In the simplest embodiments, a person gathers a suitable quantity of snow into her hands and compresses and molds the gathered snow into a ball. The person then may throw it without it “breaking up” because the compressive formation creates a solid snowball. Without the compression, the handful of snow cannot be thrown very far.
There are a couple of disadvantages to the prior art. One is that the person must use his hands to gather and compress the snow. Because the snow is cold and compressing the snow results in a certain amount of melting, the person's hands quickly become wet and cold, often limiting the duration of snowball making and throwing activities. In particularly cold weather, there may be some personal health risk to extended periods of snowball manufacture.
A second disadvantage is that snow varies widely in its density and nature. Some snow requires a great deal of compressive force to form into suitable snowballs. Other snow may be particularly icy and difficult to gather. Snow having nearly ideal conditions for hand formation is not always available, and the quality and duration of snowball formation and throwing activities again may be limited.
The prior art has developed a device to aid in snowball formation. An example of such a device is shown in U.S. Pat. No. 5,080,572 entitled “SNOW BALL MAKING DEVICE” that issued on 14 Jan. 1992. The abstract of the patent describes the device:
A snow ball making device is provided which includes a pair of elongated arms each of which has a first handle end and a second working end. These arms are pivotally secured to each other at a location intermediate their first and second ends, preferably within angled portions which connect longitudinally spaced parallel portions of the respective arms. The working end of each arm is provided with an open semi-spherical cup portion, such that the handle ends of the elongated arms are manipulable to move the semi-spherical cup portions between open and closed positions. In the closed position, the open semi-spherical cup portions are in flush engagement so as to insure the formation of a substantially spherical snow ball.
This device operates by gathering snow into the two semi-spherical cup portions and operating the two handles using one hand per handle. Operating the handles compresses the snow and forms it into a “substantially spherical” snow ball. The user removes the ball for use. While the device overcomes some disadvantages of using one's hands, there remain disadvantages to using it. These disadvantages include finding a way for the device not to interfere or get lost while throwing the snow ball, and the user is still left with handling the cold, wet snow ball with her hands during throw preparation and launch.
What is needed is another solution to snow ball formation that overcomes some of the disadvantages of the prior art while preserving the benefits.
Disclosed is an apparatus, including a shaft; a scoop, coupled to a distal end of the shaft, for collecting and holding a bolus of a compressible medium, the compressible medium retaining a post-compressed shape when operated from a proximal end of the shaft; and a former, coupled to the scoop and mating with the scoop, for molding and compressing the bolus into a generally spherical ball retained within the scoop. A method for forming a throwable ball, includes scooping a bolus of a compressible medium with a scoop coupled to a distal end of a shaft, the compressible medium retaining a post-compressed shape; and molding compressively the bolus into the scoop using a former coupled to the distal end, wherein the molding step creates the ball retained in the scoop when a user operates a proximal end of the shaft. A method for throwing a snow object, including operating a proximal end of a shaft having a snow object maker coupled to a distal end of the shaft to gather a bolus of snow into the snow object maker, the snow object maker having a scoop, coupled to the distal end, for receiving the bolus into a first concave portion, the first concave portion directed away from an operator when the proximal end is held for operation; and a former, operatively coupled to the scoop, for compressively molding the bolus into the throwable object by selectively engaging a second concave portion of the former with the bolus received into the first concave portion; molding the bolus into the throwable object by manipulation of the proximal end to operate the former; and swinging the shaft through an arc by operating the proximal end to launch the throwable object from the first concave portion.
The preferred embodiment permits a user to single-handedly gather snow, form the gathered snow into a ball, and throw the ball, all without ever touching the snow or ball with the user's hand or hands. Periods for snowball-related activities are able to be extended, user's are enabled to throw bigger snowballs greater distances for longer periods of time. One of the user's hands may be available for other actions/uses while making and throwing snowballs using the device. New activities are enabled using the preferred embodiment, such as for example, snowball-making/throwing activities while sledding, skiing, boarding, skating and the like. The device may be incorporated into available sport implements (e.g., a ski pole) or used as an adjunct to the tools of the sport.
These and other novel aspects of the present invention will be apparent to those of ordinary skill in the art upon review of the drawings and the remaining portions of the specification.
The present invention relates to an object launcher, and specifically to a single-handed device for engaging the object with the launcher, and more specifically to forming and throwing a snowball using the same apparatus, and most specifically to single-handedly forming a snowball using an apparatus and thereafter using the apparatus to launch the snowball thereby formed. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements. Various modifications to the preferred embodiment and the generic principles and features described herein will be readily apparent to those skilled in the art. Thus, the present invention is not intended to be limited to the embodiment shown but is to be accorded the widest scope consistent with the principles and features described herein.
Shaft 105 is constructed sufficiently rigid and flexible for the intended application, but preferably is constructed of a solid molded plastic or extruded aluminum tube body having about eighteen to about thirty inches of length. Shaft 105 has a proximal end and a distal end, and includes a handle 125 at the proximal end and scoop 110 coupled at the distal end. In some implementations and embodiments, shaft 105 has a variable length and/or a variable flexibility resulting from telescoping elements or from mutually cooperating elements that otherwise slide relative to each other. A variable length shaft is useful for adapting system 100 for use by users of different heights, among other advantages, while the variable flexibility shaft is useful for adapting system 100 to different conditions for objectizing and launching objects. Generally, as the flexibility of shaft 105 increases, objects may be launched greater distances. However, as shaft 105 also supports the collecting of an object, as the flexibility of shaft decreases, objects are often easier to be collected.
Scoop 110 serves as a preferred objectifier, which in the preferred embodiment includes collecting and holding a bolus of a compressible medium. This compressible medium includes snow or other substance that is able to be formed and shaped into a ball that retains its shape after forming/shaping. Scoop 110 may also select a single item from a collection of items and retain it within a cavity. The cavity of scoop 110 is preferably one-half of a sphere that holds the bolus after it is collected. Scoop 110 may be inclined relative to a longitudinal axis of shaft 105. Inclination of scoop 110 is adapted to assist in objectizing and for launching objects from within the cavity.
In some embodiments and implementations, scoop 110 is coupled to shaft 105 using a mounting system that permits different lengths of shaft 105 to be used in cooperation with scoop 110. For example, a threaded end at the distal end of shaft 105 may be used to mount to complementary threaded portion in scoop 110. Additionally, the mounting system may provide for varying the inclination angle according to a user preference.
Former 115 is a mating element cooperating with scoop 110 for objectizing an object or medium. In the preferred embodiment, former 115 includes a spherical cavity matching the cavity in scoop 110 for use as a compactor/former/shaper of the bolus. Former 115 includes two positions relative to scoop 110, a closed position and an open position. In the closed position, former 115 compresses the bolus and presses it into scoop 110 to form a generally spherical ball of the compressible medium (e.g., a snowball). In the open position after ball formation, the ball is retained within scoop 110 and former 115 pivots down and away from scoop 110. In the open position, former 115 does not interfere with a launching of the ball from scoop 110 when shaft 105 is swung in an arc about handle 125. Former 115 is also positioned relative to scoop 110 and shaft 105 to permit former 115 to be operated from single-handed manipulation of handle 125, such as, for example, tapping former 115 against the ground or other object or structure to move former 115 from the open position to the closed position.
In the preferred embodiment when scoop 110 and former 115 define matching semi-spheres, the closed position juxtaposes the two structures together sufficiently to form the bolus into the desired shape. This juxtaposition need not be completely closed, or even in some cases mostly closed. The degree of closure depends upon the nature and condition of the compressible medium and the user's desire to collect, shape and form balls of varying quality. Typically, the “best” balls are formed when scoop 110 and former 115 are completely closed, but these “best” balls may be perceived to require extra time to form by completely closing the elements. Balls of lesser quality (produced from less proximate juxtapositions) may be produced faster, thus more balls per unit of time may be launched.
In other embodiments, former 115 is a trapper that simply retains an object within the cavity of scoop 110 while the object is collected. Scoop 110 and former 115 are preferably molded plastic semi-spheres, though other shapes and materials may be used. In some conditions, scoop 110 may require extra stiffness and/or use of a cutting edge along all or a portion of a periphery of the cavity to efficiently collect sufficient quantities of the compressible medium.
Biasing system 120 of the preferred embodiment includes an elastomeric band coupled between former 115 and shaft 105 to bias former 115 into the open position. The elastomeric band is replaceable and preferably provides a sufficient biasing force to maintain former 115 in an open or semi-open position so as to not interfere with a launch of an object from within a cavity of scoop 110. In some configurations, former 115 will tend to the closed position as shaft 105 is swung through the arc, and that tendency is increased as shaft 105 becomes longer or the speed of the swing or of scoop 110 increases. Other biasing systems may be used, to pull, push or otherwise separate former 115 from scoop 110 and induce former 115 into the open position.
In operation, a user operates system 100 through single-handed manipulation of handle 125. The user collects the bolus of the compressible medium (e.g., snow) into scoop 110. In some instances, the collection is achieved by scooping up a sufficient quantity to overflow the cavity of scoop 110, and in other instances, scoop 110 is plunged into a large quantity of the medium, or former 115 is used as a “plow” to produce a suitable pile of medium that may be collected by scoop 110.
The user then manipulates handle 125 to cause former 115 to be juxtaposed sufficiently to scoop 110 to form the desired shape and consistency ball. The user achieves this by urging former 115 against the ground, building, other structure or other object to move it towards the closed position. In the preferred embodiment, it is accomplished by “tapping” former 115 against the ground to compress/pack and form the desired ball.
Releasing the closing force permits biasing system 120 to move former 115 to the open position. This retains the ball within the cavity of scoop 110. The user may then, when desired, swing shaft 105 about an arc to launch the ball from the cavity of scoop 110 towards the desired target. System 100 is ready to collect and form other balls in quick succession.
In operation, when former 115 is moved sufficiently close to activate latching mechanism 505. Thereafter, former 115 does not open to permit launching of an object in scoop 110 until release 510 is actuated. In this configuration, the user would actuate release 510 immediately prior to launch. In this configuration, system 500 may be used to launch virtually any object that fits within scoop 110 and former 115.
Scoop 710 is shifted relative to shaft 705 to enable scooping without interfering with the ski pole function. Shaft 705 need not be coupled to a “rim” of scoop 710, but could be attached nearly tangential to scoop 710. Similarly, former 715 may be desirably “side-mounted” to enable former 715 to be tapped closed without interfering with the ski pole functions.
The above-described arrangements of apparatus and methods are merely illustrative of applications of the principles of this invention and many other embodiments and modifications may be made without departing from the spirit and scope of the invention as defined in the claims.
These and other novel aspects of the present invention will be apparent to those of ordinary skill in the art upon review of the drawings and the remaining portions of the specification.
