Abstract
A diving stick of the type which, after being tossed into a swimming pool, sinks to the bottom while maintaining an upright posture so that it can easily be grasped by a diver, includes a soft malleable outer body designed to prevent accidental impalement, and provisions for enabling the diving stick to sink and maintain an upright posture at the bottom of the pool despite the buoyancy of the soft malleable material.
Claims9
An elongated object arranged to be tossed into a body of water, sink to a bottom of the body of water, and rest on the bottom while maintaining an upright posture so that it can easily be retrieved by a diver, comprising:
- an outer body made of a soft and malleable enough to prevent impalement of the diver, said outer body including an interior chamber and an exterior opening in communication with the interior chamber, said interior chamber having a volume large enough to accommodate sufficient ingress of water when the outer body is tossed into the body of water to overcome a buoyancy of the outer body, and thereby cause the elongated object to sink,
- wherein said outer body has first and second ends, and
- wherein when said elongated object is initially tossed into said body of water, said elongated object maintains a substantially horizontal orientation until said ingress of water occurs, a weight of the first end of the elongated object being insufficient by itself to cause a change from said substantially horizontal orientation to a vertical orientation, and
- a weight confined to the first end of said outer body,
- wherein the first end of the outer body is adapted to sink before the second end upon said ingress of water into said interior chamber to thereby cause said outer body to change from a horizontal orientation in which the outer body floats upon said surface to a vertical orientation as the outer body sinks below said surface, and to maintain said vertical orientation as it sinks to the predetermined level,
- wherein said outer body includes at least one opening at said second end of the outer body for permitting egress of air from said interior area to outside said outer body in response to the ingress of water,
- wherein said second opening is spaced from the second end of the body so that a pocket of air is present in said second end to cause said stick to maintain the upright posture as the elongated object is filled with water,
- wherein said elongated object further comprises a removable end cap at said first end of the outer body, said end cap being arranged to be removed to permit access to said weight, and
- wherein said weight is confined between the end cap and a flange extending inwardly from said outer body.
A diving stick arranged to be tossed into a body of water, sink to a bottom of the body of water, and rest on the bottom while maintaining an upright posture so that it can easily be retrieved by a diver, comprising:
- an outer body made of a material soft and malleable enough to prevent impalement of the diver,
- wherein said outer body has first and second ends,
- wherein a weight of said first end of the outer body is insufficient to cause said outer body to change from an initial substantially horizontal orientation to a preferred upright posture upon being tossed into said body of water, and
- wherein said first end of said outer body is nevertheless adapted to sink below the surface before the second end of said outer body sinks below the surface and to cause the outer body to maintain said preferred upright posture as it sinks to the bottom of the body of water and rests on the bottom, and
- further comprising a weight made up of sand confined in a separate enclosure at said first end of the object.
A diving stick arranged to be tossed into a body of water, sink to a bottom of the body of water, and rest on the bottom while maintaining an upright posture so that it can easily be retrieved by a diver, comprising:
- an outer body made of a material soft and malleable enough to prevent impalement of the diver,
- wherein said outer body has first and second ends,
- wherein a weight of said first end of the outer body is insufficient to cause said outer body to change from an initial substantially horizontal orientation to a preferred upright posture upon being tossed into said body of water, and
- wherein said first end of said outer body is nevertheless adapted to sink below the surface before the second end of said outer body sinks below the surface and to cause the outer body to maintain said preferred upright posture as it sinks to the bottom of the body of water and rests on the bottom, wherein said outer body includes an opening at said first end of the body for permitting ingress of water into an interior area defined by an outer surface of the outer body, and at least one opening at said second end of the outer body for permitting egress of air from said interior area to outside said outer body in response to the ingress of water, and further comprising a weight confined to the first end adjacent the first opening, and wherein said second opening is spaced from the second end of the body sufficient to cause a pocket of air to be present in said second end and thereby cause said stick to maintain the upright posture as the stick is filled with water.
