Abstract
A bowling pin including a body having a head, a neck, a ball line portion, and a base all integrally formed of a synthetic material. The body includes a hollow area and a longitudinal axis of the hollow area extends generally perpendicularly to a substantially planar bottom surface of the base. A method of manufacturing a bowling pin includes providing a mold shell having a mold cavity shaped substantially as a bowling pin, disposing a mandrel inside a mold cavity, introducing material into the mold cavity, cooling the material inside the mold cavity, removing the mandrel from the mold cavity, removing the material from the mold cavity, and cooling the material outside the mold cavity.
Claims21
A howling pin, comprising:
- a body comprising a head, a neck, a ball line portion, and a base all integrally formed of a synthetic material, the neck connecting to head and the ball line portion;
- and
- a hollow area extending from a substantially planar bottom surface of the base into the body and extending at least into the neck with a portion having a smallest diameter of the bowling pin, and having a longitudinal axis generally perpendicular to the bottom surface, wherein:
- the body forms an exposed exterior surface of the bowling pin, and
- the hollow area comprises a generally conical shape with a sidewall having a generally constant gradient along a majority of an axial length of the hollow area.
A bowling pin, comprising:
- a body having a head, a neck, a ball line portion, and a base all integrally formed of a synthetic material;
- hollow area which terminates within the body and which has a longitudinal axis substantially perpendicular to a substantially planar surface of the base;
- a base attachment connected to the base;
- and
- an insert disposed within the hollow area at a location where the hollow area terminates within the body,
- wherein in the body forms an exposed exterior surface of the bowling pin and the hollow area includes a generally constant decreasing gradient along a majority of an axial length.
