Patent ID: 7448371

Claim:
A device for projecting an object, the device comprising: a projectile mount configured to hold an object to be projected; a housing; a retractor mechanism coupled by a linkage to the projectile mount for producing movement of the projectile mount relative to the housing; at least one resilient member, at least one end of the resilient member being coupled to the housing, and the resilient member engaging the retractor mechanism, wherein relative movement of the retractor mechanism away from the housing stores energy in the resilient member, and relative movement of the retractor mechanism towards the housing transfers the stored energy into movement of the projectile mount, wherein the at least one resilient member includes a band of elastic material, at least a portion of the at least one resilient member being positioned externally of at least a portion of the housing; and wherein the retractor mechanism further comprises a connector plate, wherein the projectile mount is removably coupled to the connector plate.
