摘要:
Apparatus for projecting an object such as a ball is described. The apparatus comprises a support for the object to be projected, an impeller assembly configured to transfer energy to the object to project it away from the apparatus; and an actuating mechanism operable by a user interaction with the apparatus. The impeller assembly may be driven mechanically by the actuating mechanism by transfer of energy input by the user interaction. The apparatus may be used for an animal and in particular a dog. The described apparatus removes the need for a further power supply and so avoids unnecessary energy consumption and provides advantages in relation to cost, reliability, and longevity. Embodiments of the invention are modular in nature which greatly assists in training the animal to use the apparatus.

The invention consists in a throwing apparatus comprising an elongated handle and a cup mounted on the handle at or adjacent one end thereof. The cup is shaped to receive a throwable, non spherical, object and to retain such object until the handle is swung whereupon the object is released from the cup.

A ballistic impeller golf club includes a piston (67) and an explosive charge (117) disposed within the head of the golf club. The piston (67) is adapted to travel outwardly from the club head in response to a rapidly expanding gas produced by the explosive charge. A golf ball, disposed proximate to the club, is struck by the piston, thereby causing the golf ball to travel a predetermined distance.

The invention consists of a device for manually sending and receiving an object such as a ball in the context of a sporting or leisure activity. This launcher is made up of two separate rigid parts (e.g. in the form of sticks) and a flexible trapezium-shaped surface by way of a sending and receiving zone. The object is received by holding the handles sufficiently close together to form a pocket to absorb the impact of the object striking the flexible surface. The object is sent by suddenly drawing the hands apart to the maximum distance permitted by the width of the flexible surface, using their natural fan-like parting movement. It is the tension created by the stretching of this surface which ejects the object and sends it very long distances with only the hands for motive force.

The present invention relates generally to methods and devices for projecting articles. In particular, the present invention relates to a method and apparatus for projecting balls and like articles for interaction with a player where a player may, for example, be considered a human training for or playing a ball sport or, an animal such as a dog exercising by retrieving the projected article. In one form, the invention relates to a method and apparatus for projecting an article comprising: feeding at least one article into a launching means wherein the launching means comprises a plurality of independently controlled rotating drive devices each device adapted to provide contact between the launching means and the at least one article for providing a component of drive force to launch the at least one article; attenuating at least one component of drive force to control the 3-Dimensional spin of the launched article by moving at least one drive device whilst maintaining the orientation of the axis of rotation of said drive device.

Ball game practice apparatus, particularly for tennis practice, comprising a ball catching assembly (2) and a ball collecting assembly (3), which in its turn comprises at least a first chute (30) beneath the ball catching assembly, said ball catching assembly being connected with a ball propulsion assembly (5) via a ball feeding assembly (4). A characteristic feature of the invention is that in the ball collecting assembly (3) between the chute (30) and the ball catching assembly (2) there is a damping device (32), through which the balls must pass and which damps the falling speed of the balls to prevent them from leaving the ball collecting assembly (3) by rebounding from the bottom (33) of the chute. Another characteristic feature of the invention is further that the bottom of said at least first chute (30) consists of a plane, preferably sloping only in the longitudinal direction of the chute.

The invention relates to a game (1) for throwing and receiving a ball or a shuttle, comprising a basket (20) articulated around two rigid walls (21, 23) and elastic means (22, 24) so as to project the ball or the shuttle at a certain speed by stretching the game (1), at the same time facilitating the reception of the projectile in the articulated basket (20) when the game (1) is in the idle position.
