US 4,050,439 A · Accurate adjustable sling-shot

Abstract

A sling-shot device comprises, in basic assembly, an enclosed, generally circular "tine" section or impeller holder fixed on the grip or handle portion of the assembly with provision in said circular "tine" section for angularly and rotatably adjusting the secured ends of the elastic power band or the like or equivalent sling or impeller member, said ends being mounted secure at more or less diametrically opposed points located circumferentially on said circular "tine" section so that at least substantially perpendicular aiming (or sighting) and "firing" of the sling-shot is facilitated regardless of the position assumed in operational holding of the sling-shot when other-than-perpendicular (to the ground) handle dispositions are encountered; this accommodating a natural and most comfortable and desired body stance and head-cocking positional relationship assumed because of individual physique, style and mannerism for any given shooter using the sling-shot.

Dependent claims

In a sling-shot assembly having a frame head portion with a handle portion depending therefrom to which frame head portion there is attached an aligned extensible elastic sling band for generally non-elongate missile hurling without physical missile guide means thereabout which extensible sling band is securely attached by the disconnected ends of said sling band at spaced points on and to the frame head portion of the body of the sling-shot that is over it's handle portion:

means rotatable in a substantially vertical plane in combination in said sling-shot for adjusting the points at which said disconnected ends of said sling band are secured and fixed to said frame head so that,
during operational usage of the sling-shot disposed in given situation according to the mode of grasp and stance employed by the user, the said points are disposed and situate relative to one another and to level ground in a plane that is at least substantially parallel to and with the plane of the level ground.

Sling-shot comprising, in cooperative assembly:

a body unit having a generally circular and flatly cylindrical frame head portion with mounting faces on each side thereof which is supermounted over and joined with an extending handle grip portion
said frame head portion being so configured as to form within its confines an at least substantially round opening in said frame head which opening gives free passage of missiles hurled out of and propelled for flight from the sling-shot by the provision of extensible, elastic sling-band means in the sling-shot,
said elastic sling-band means mounted in said sling-shot;
at least a single generally washer-like sling band bearing ring positioned in fixable but rotatably movable engagement having faces on each side thereof with one of its faces on and against one of the mounting faces of said cylindrical framehead, the inner diameter of each of said rings having at least approximately the diameter of said opening in the frame head;
each of said rings being concentrically positioned in the assembly with respect to said opening;
the respective disconnected ends of said sling-band means being mounted upon and securely attached to and with at least one of said rings at at least approximately diametrically opposed points of securement for said ends on the peripheral area of each of the rings;
means for locking each of said rings in predetermined relative disposition placement on the face of said frame head on which each ring mounting is made;
and
means for loosening each of the ring in the mounting on the face of the frame head portion to permit rotational movement thereof;
whereby and whereupon
adjustment of the diametrically opposed points of securement of said sling band on and with each and every of said rings may be made so that said points are then rotatably movable to another disposition wherein they are then disposed if not so positioned so as to generally lie in any plane relative to the general center line of the handle portion of said sling-shot including that plane, during operational usage of the sling-shot, which is at least substantially parallel with the plane of level ground.

Sling-shot comprising, in cooperative assembly:

a body unit having a generally cicular and flatly cylindrical frame head portion with mounting faces on each side thereof which is supermounted over and joined with an extending handle grip portion;
said frame head portion being so configured as to form within its confines
an opening in the interior space of said frame head portion which opening has adequate dimensional space therein to give free passage of missiles hurled out of and propelled for flight from the sling-shot;
an extensible, elastic sling band mounted in said sling-shot;
at least a single generally arcuately formed sling band bearing collar positioned in fixable but rotatably movable engagement on and against one of the mounting faces of said frame head portion, the inner dimension of each of said collars having at least approximately the dimensional space of said opening in the frame head portion;
each of said collars being concentrically positioned in the assembly with respect to said opening;
the respective disconnected ends of said sling band being mounted upon and securely attached to one of said at least a single collar at oppositely spaced points of securement for said ends on the peripheral area of the said at least a single collar;
means for locking said at least a single collar in predetermined relative disposition placement on the mounting face of said frame head portion on which the said at least a single collar mounting is made;
and
means for loosening said at least a single collar in the mounting on the face of the frame head portion to permit rotational movement thereof;
whereby and whereupon
adjustment of the opposed points of securement of said sling band on said at least a single collar may be made so that said points are then rotatably movable wherein they are then disposed if not so positioned so as to generally lie in any plane relative to the general center line passing through the middle of the handle portion of said sling-shot including that plane, during operational usage of the sling-shot, which is at least substantially parallel with the plane of level ground.
