Abstract
A ball projecting apparatus includes a housing with a frontward opening. The interior of the housing has an elongated ball guider which extends inclinedly and longitudinally from a position near the frontward opening and which terminates at a lower position, an electrically driven rotor which is mounted below the elongated ball guider, and a torsion spring which is mounted pivotally to the housing. The torsion spring has a first end portion which engages by a stopper and a second end portion which extends into a circular path that is traveled by the rotor when the rotor is activated.
Claims11
A ball projecting apparatus comprising:
- a housing with a frontward opening;
- an elongated ball guider provided in said housing having a longitudinal slot formed therealong, said elongated ball guider extending inclinedly and longitudinally from a position near said frontward opening to a lower position of said housing;
- an electrically driven rotor mounted in said housing below said elongated ball guider, said rotor having at least one lobe with a free end, said free end revolving with said lobe along a circular path when said rotor is driven;
- a torsion spring mounted pivotally in said housing, said torsion spring having a first end portion and a second end portion opposite to said first end portion extending into said circular path via said longitudinal slot;
- stopper disposed in said housing and engaging said first end portion of said torsion spring;
- and
- means for sensing said ball in said elongated ball guider to drive said rotor,
- wherein, said torsion spring can be triggered by said rotor to project a ball in said elongated ball guider out of said housing via said frontward opening.
A ball projecting apparatus comprising:
- a housing with a frontward opening and first and second halves;
- an elongated ball guider provided in said housing having first and second longitudinal plates which cooperatively form a longitudinal slot formed therebetween, said first longitudinal plate being integral with said first half of said housing, said second longitudinal plate being mounted pivotally on said second half of said housing, said elongated ball guider extending inclinedly and longitudinally from a position near said frontward opening to a lower position of said housing;
- an electrically driven rotor mounted in said housing below said elongated ball guider, said rotor having at least one lobe with a free end, said free end revolving with said lobe along a circular path when said rotor is driven;
- a torsion spring mounted pivotally in said housing, said torsion spring having a first end portion and a second end portion opposite to said first end portion extending into said circular path via said longitudinal slot, wherein said torsion spring can be triggered by said rotor to project a ball in said elongated ball guider out of said housing via said frontward opening;
- a stopper disposed in said housing and engaging said first end portion of said torsion spring;
- and
- a switch below said second longitudinal plate and electrically connected to said rotor, said switch having an actuating rod which bears against said second longitudinal plate and which enables said rotor to operate when said second longitudinal plate is depressed by said ball disposed thereon to further depress said actuating rod.
