An inflatable tube ski vehicle with steering mechanism comprises an inflated, torus-shaped tube or bladder and a ski insert disposed in the central opening of the bladder. The ski insert may be dish-shaped, or it may partially wrap around the top and/or bottom of the bladder. In either case, the ski
An inflatable tube ski vehicle with steering mechanism comprises an inflated, torus-shaped tube or bladder and a ski insert disposed in the central opening of the bladder. The ski insert may be dish-shaped, or it may partially wrap around the top and/or bottom of the bladder. In either case, the ski vehicle has a steering/braking mechanism comprising left and right lever arms pivotally attached to and extending down through the ski insert. To turn, a rider simply pulls on one of the lever arms, causing a lower portion of the lever arm to extend past a bottom of the insert. To brake, both arms are pulled simultaneously. Because the ski vehicle is round and because the weight of the vehicle and rider are largely uniformly distributed over the center of the vehicle, a pivot or fulcrum point occurs directly under the rider's seat, affording a significant degree of control.

A shooting game machine having a gun for projecting bullets using compressed air and targets arranged in a predetermined distance in front of the gun, comprising: a housing which is provided with at least one opening formed on a front wall thereof; a gun supporter mounted inside of the opening on the front wall of the housing for supporting the gun; and a target holding mechanism installed in front of the gun in a predetermined distance for holding at least one target wherein the target holding mechanism comprises: movable means for moving the targets; driving means for driving the movable means; and at least one target holder horizontally mounted to the movable means, the target holder being provided with at least one slot having a shape of "T". 9. The shooting game machine of claim 8 further comprising: at least one target for being inserted into the slot of the target holder and suspended therefrom wherein the target is provided with a body and a suspender connected to the body via a neck. 10. The shooting game machine of claim 9 wherein the slot of the target holder is provided with a wide portion having a same width as the suspender of the target in order for the suspender to be inserted into the slot through the wide portion and a holding portion for holding the suspender of the target. 11. The shooting game machine of claim 10 wherein the target is suspended from the target holder by inserting the suspender through the wide portion of the slot and pulling down the target such that the neck of the target is engaged with a holding portion and the suspender is held. 12. A shooting game machine having a gun for projecting bullets using compressed air and targets arranged in a predetermined distance in front of the gun, comprising: a housing which is provided with at least one opening formed on a front wall thereof; a gun supporter mounted inside of the opening on the front wall of the housing for supporting the gun; a target holding mechanism installed in front of the gun in a predetermined distance for holding at least one target; and a plurality of elastic members applied on a surface of a plate of an inner wall of the housing for cushioning impact of the bullet against the inner wall. 13. The shooting game machine of claim 12 wherein the elastic members are rubber. 14. The shooting game machine of claim 13 wherein the elastic members have a shape of a tapered column projected from the plate. 15. The shooting game machine of claim 12 wherein the front wall of the housing is made out of a transparent plate. 16. The shooting game machine of claim 15 wherein the gun supporter comprises: a rotation ring having an outer diameter less than that of the opening; a pair of connectors rotationally the connecting rotation ring with the front wall in the opening at upper and lower end portions of a circumferential edge of the opening; and a pair of studs connecting the gun to the rotation ring such that the gun rotates on an axis of the studs perpendicular to an axis on which the rotation ring rotates. 17. The shooting game machine of claim 16 wherein each connector comprises: a connecting bracket having a shape of "U" such that an indented portion is engaged with circumferential edge of the opening of the front wall; and a cylindrical shaft of which one end is fixed to the connecting bracket and the other end having a stepped portion for rotationally connecting with the rotation ring. 18. The shooting game machine of claim 17 wherein the rotation ring has a pair of projections perpendicularly projected from the rotation ring at a longest distance therebetween on the rotation ring an respective connection holes such that the stepped portions of the shafts are rotationally received in the respective connection holes. 19. The shooting game machine of claim 18 wher ein the studs are oppositely and coaxially fixed on the rotation ring at an angle of 90° relative to the projections of the rotation rings. 20. The shooting game machine of claim 19 wherein each stud has a stepped end portion having a smaller diameter than that of the stud and threaded such that the gun is rotationally mounted between the studs in the rotation ring. entation of said actuator within said housing. 7. The equalizing chuck assembly of claim 1 wherein each of said rocker arms has an intermediate spherical portion supported in a bearing assembly disposed in an aperture formed in said front face of said housing. 8. The equalizing chuck assembly of claim 1 further comprising a plurality of stops, each of said plurality of stops disposed on said front face adjacent a corresponding jaw member. 9. The equalizing chuck assembly of claim 1 further comprises an adaptor plate secured to an end of said housing opposite said front face. 10. The equalizing chuck assembly of claim 1 wherein each of said counterweights are generally D-shaped having a flat surface inwardly oriented. 11. The equalizer chuck assembly of claim 1 wherein each of said plurality of jaw members has a bore formed therein, said bore receiving said first end of said rocker arm. 12. A equalizing chuck assembly comprising: a housing having a front face; an actuator supported for axial motion in said housing and positionable between a first axial position and a second axial position; a first chucking mechanism including a first equalizing plate pivotally connected to said actuator so as to move axially therewith and rotate relative thereto, a first pair of rocker arms pivotally coupled to said housing, each of said first pair of rocker arms having a first end extending through said front face, a second end opposite said first end, a jaw member secured to said first end, a counterweight secured to said second end and a toggle link operably connecting said second end to said first equalizing plate; a second chucking mechanism including a second equalizing plate pivotally connected to said actuator so as to move axially therewith and rotate relative thereto, a second pair of rocker arms pivotally coupled to said housing, each of said second pair of rocker arms having a first end extending through said front face, a second end opposite said first end, a jaw member secured to said first end, a counterweight secured to said second end and a toggle link operably connecting said second end to said second equalizing plate; a third chucking mechanism including a third equalizing plate pivotally connected to said actuator so as to move axially therewith and rotate relative thereto, a third pair of rocker arms pivotally coupled to said housing, each of said third pair of rocker arms having a first end extending through said front face, a second end opposite said first end, a jaw member secured to said first end, a counterweight secured to said second end and a toggle link operably connecting said second end to said third equalizing plate; wherein axial movement of said actuator between said first position and said second position pivots said rocker arms, thereby moving said jaw members between an open position and an closed position. 13. The equalizing chuck assembly of claim 12 wherein each of said first, second and third chucking mechanisms further comprises a pair of bearing assemblies disposed in said equalizing plate, each of said pair of bearing assemblies being operably coupled to a respective rocker arm through a respective toggle link. 14. The equalizing chuck assembly of claim 12 wherein each of said first, second and third chucking mechanisms further comprises a centralizing pin extending from an interior surface of said housing, said centralizing pin engaging said equalizing plate when said actuator is moved to said first position. 15.
