Definitions

  • the invention relates to a device for launching small objects, specifically balls or pellets or other small objects, consisting of a standing part and a launching part.
  • a game of table football is known, for example, in which the player figures are attached to the playing surface by a spring.
  • the figure is pre-stressed on a spring against the direction of the ball's launch by the hand or finger. After releasing, the figure abruptly springs back, and impacts the ball to launch it in the desired direction.
  • the figure here simultaneously forms the standing and launching part.
  • Document EP I 685 881 describes a different design for the playing figures for table football or another table ball game.
  • the playing figure has a single support leg fixed to the playing surface which together with the body forms the standing part, and a single movable leg which is rotatably mounted on an axis on the standing part and at the connection with the body of the figure is provided with a spring so as to form the launching part.
  • the launching part is twisted backwards into the tension position. After releasing, the launching part, through the tension of the spring, is expelled and rapidly returns to its resting position, thereby launching the playing ball.
  • Document US 2 289 421 describes a playing figure, specifically a bowler, whose body forms the standing part and whose arms form the launching part, equipped with a spring in its shoulder.
  • the arm is held in the tension position by a movable pin. Releasing the pin springs the arm back, launching the ball.
  • the disadvantages of the aforementioned playing figures lie in the fact that in order to function correctly, they require a solid surface to which they are attached.
  • the game thus makes high demands for space.
  • the manufacture of the above described playing figures with their respective playing surfaces is demanding in terms of cost and material.
  • the overall game, respectively the device, is expensive and difficult to carry, and its use is limited.
  • the invention aims to provide a device which would remedy the above disadvantages, would be small, easily portable, inexpensive, easy to grip by left- and right-handers, and would be simple to manufacture, while providing other uses such as promotional use.
  • the device consists of a standing part, a launching part rotatably mounted to the standing part, and of an elastic element for storing energy during the rotation of the launching part in one direction and for releasing energy during the rotation of the launching part and launching the object in the opposite direction.
  • the essence of the invention lies in the fact that the launching part is formed by a tension arm and a launch arm.
  • the mutually adjacent ends of the tension arm and the launch arm are provided with a means for coupling the rotary movement of the tension arm and the launch arm, and at least one of the arms is connected with an elastic element for storing energy during the movement of the averted ends of the arms towards each other into the tension position, in which the arms essentially form the shape of the letter "V", and for releasing the stored energy during the return movement of the arms into the resting position.
  • each arm has its own axis of rotation.
  • the tension arm is rotatably mounted to the standing part on its own axis of rotation of the tension arm
  • the launch arm is rotatably mounted to the standing part on its own axis of rotation of the launch arm.
  • the axes of rotation are arranged at mutually adjacent ends of the arms arranged in a central region of the launching part.
  • the elastic element consists of a rubber strip connecting the tension arm and launch arm at their outer side opposite the direction of tension.
  • the outer placing of the elastic element is suitable e.g. for embodiments in which the ends of the arms are provided with cogged segments.
  • the elastic element is a thin steel strip connecting the tension arm and the launch arm at their point of contact.
  • the strip is slidably mounted at its one end in a casing formed as a recess in the tension arm, while its other end is slidably mounted in a casing formed as a recess in the launch arm.
  • the steel strip functions as a means for storing and releasing energy as well as a means for coupling the movement of the tension arm and launch arm. When the arm moves into the tension position and back to its resting position, the steel strip bends while moving in its casing due to changes in its length during bending.
  • the elastic element is formed by a rubber strip interconnecting the arms and mounted at one of its ends in a casing formed as a recess in the tension arm, while its other end is mounted in a casing formed as a recess in the launch arm.
  • the shape of the rubber strip is adaptable, so it can be mounted in a fixed position into both casings, especially when using softer and more flexible rubber.
  • the function of the rubber strip is the same as the function of the steel strip.
  • the elastic element is formed by a coil spring arranged between the standing part and the launching part.
  • the coil spring By arranging the coil spring on the axes of rotation of the arms forming the launching part, multiplied force is achieved for springing the launch arm. It is possible, however, to deploy a coil spring only on one axis of rotation. The function remains the same, only with reduced springing force of the launch arm.
  • the means for coupling the rotary movement of the tension arm and launch arm can be solved in many different ways, in one preferred embodiment, this means is formed by cogs formed on the tension arm and cogs formed on the launcher arm, wherein the cogs of the tension arm and the cogs of the launch arm mesh together at the point where the two arms meet. This may be cogged segments at the ends of the arms, inner cogged surfaces at the interface area where the two arms overlap, and similar.
  • the means for coupling the movement of the arms in another preferred embodiment is formed by a friction drive.
  • the function of the friction wheels of the friction drive is the same as the function of the cogs.
  • the standing part is taller than the launching part. This embodiment ensures that there is no friction between the launch arm and the surface of the base, so that its movement is not hampered during launching. It should be emphasized that the device is intended for launching objects on any hard surface and does not require a special pad.
  • the standing part is in the shape of a horizontal "U” and the tension arm and launch arm are each in the shape of the letter “L” mirrored against each other, whereby the standing part and the tension arm and the launch arm fit together.
  • This design is easy to handle and simultaneously allows the device to be turned over so that it may be used by a left-handed person.
  • the lower arm of the horizontal "U” forms the base of the device, while its upper arm and the base of the "L” forming the upper part form a support for fingers when applying tension to the tension arm.
  • the base of the "L” launch arm then has sufficient space to hit and launch a small object.
  • the advantages of the device according to the invention consist especially in the fact that no additional accessory is required for its application, it can be applied to any hard surface, and it can launch special balls as well as any small objects, e.g., rubber or paper balls, etc.
  • the device is small, easily portable, simple to manufacture, and inexpensive.
  • the surface of the device can be used for advertising purposes. Description of the illustrations
