Abstract: A toy launching assembly for pneumatically launching toy projectiles. The toy launching assembly has a base structure that contains an open port. A tube carousel rotates atop the base structure. The tube carousel holds a plurality of launching tubes. A pulse of air is generated by rapidly compressing an air bladder. The pulse of air travels through an air hose to the base structure. Within the base structure, the pulse of air is directed to the open port under the tube carousel. An indexing mechanism is used to rotate the tube carousel and sequentially positions one of the launching tubes over the open port each time the air bladder is sufficiently compressed. Once positioned over the open port, the pulse of air generated by the air bladder travels through the launching tube and displaces a toy projectile from the launching tube.

Abstract: Exemplary embodiments of a gas pressure regulator comprise a regulator body, an adaptor sleeve, a retainer and an indexing ring. The regulator body includes a proximal portion, a distal portion, a ported intermediate portion therebetween, and a main bore. The adaptor sleeve axially receives the distal portion and includes an outer threading for engaging an air source adaptor of a paintball marker. The retainer threadably engages the main bore within the distal end, thereby axially securing the adaptor sleeve onto the distal end. The indexing ring receives the distal portion therethrough for resiliently biased axial movement of the indexing ring between a locking position and an unlocking position. When the indexing ring is in its unlocking position, the adaptor sleeve is rotatable with respect to the regulator body. When the indexing ring is in its locking position, the adaptor sleeve is rendered substantially non-rotatable with respect to the regulator body.
