Abstract

Abstract A puzzle game comprising a hollow sphere having a plurality of openings randomly formed therein, each of the openings being alignable with another opening, and a plurality of pins of predetermined dimensions, each of which is selectively inserted by a player through a pair of aligned openings wherein the puzzle is solved when the length of each pin as inserted through the aligned openings generally corresponds to the dimension of the chord line which is extended just beyond the outer surface of the sphere between the aligned openings.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 202 words
A puzzle game, comprising a hollow sphere having a plurality of openings formed at random therein, each of said openings being alignable with another opening, wherein a line extending through the alignable openings defines a chord of said sphere that when extended just beyond the outer surface of the sphere has a preselected dimension, and a plurality of pins, each being of predetermined length that has a corresponding relation to the preselected dimension of a chord, wherein each of said pins is properly securable in said sphere only if it is related in dimension to a preselected chord length after being inserted through a pair of openings, each of said pins having a head on one end thereof and a threaded portion formed on the other end thereof, said head having a diameter that is greater than that of said openings wherein the head of each pin defines a stop for a pin when it is located in a pair of aligned openings, a threaded nut corresponding in size to the head of a pin and being securable to the threaded portion thereof, said nut cooperating with the head of a pin to secure the pin in a pair of aligned openings.
Claim 2
Dependent Claim 202 words
A puzzle game, comprising a hollow sphere having a plurality of openings formed at random therein, each of said openings being alignable with another opening, wherein a line extending through the alignable openings defines a chord of said sphere that when extended just beyond the outer surface of the sphere has a preselected dimension, and a plurality of pins, each being of predetermined length that has a corresponding relation to the preselected dimension of a chord, wherein each of said pins is properly securable in said sphere only if it is related in dimension to a preselected chord length after being inserted through a pair of openings, each of said pins having a head on one end thereof and a threaded portion formed on the other end thereof, said head having a diameter that is greater than that of said openings wherein the head of each pin defines a stop for a pin when it is located in a pair of aligned openings, a threaded nut corresponding in size to the head of a pin and being securable to the threaded portion thereof, said nut cooperating with the head of a pin to secure the pin in a pair of aligned openings.
Claim 3
Dependent Claim 48 words
A puzzle game as set forth in claim 1, a pin being properly securable in said sphere when the threaded portion thereof protrudes just beyond a opening in which the pin is inserted for receiving a nut thereon in substantially flush relation with respect to the end thereof.
Claim 4
Dependent Claim 27 words
A puzzle game as set forth in claim 2, said sphere being formed of a transparent plastic material, wherein said pins as secured therein are externally visible.
Claim 5
Dependent Claim 170 words
A puzzle game, comprising a hollow sphere having a plurality of openings formed at random therein, each of said openings being alignable with another opening, wherein a line extending through the alignable openings defines a chord of said sphere that when extended just beyond the outer surface of the sphere has a preselected dimension, and a plurality of pins, each being of predetermined length that has a corresponding relation to the preselected dimension of a chord, wherein each of said pins is properly securable in said sphere only if it is related in dimension to a preselected chord length after being inserted through a pair of openings, said pins being of various lengths so that only one pin is correctly insertable through any selected pair of aligned openings, each pin having a head formed on one end thereof and a threaded portion on the other end, a nut being receivable on the threaded portion after the pin is inserted through the aligned openings to lock the pin in the sphere.
Claim 6
Dependent Claim 170 words
A puzzle game, comprising a hollow sphere having a plurality of openings formed at random therein, each of said openings being alignable with another opening, wherein a line extending through the alignable openings defines a chord of said sphere that when extended just beyond the outer surface of the sphere has a preselected dimension, and a plurality of pins, each being of predetermined length that has a corresponding relation to the preselected dimension of a chord, wherein each of said pins is properly securable in said sphere only if it is related in dimension to a preselected chord length after being inserted through a pair of openings, said pins being of various lengths so that only one pin is correctly insertable through any selected pair of aligned openings, each pin having a head formed on one end thereof and a threaded portion on the other end, a nut being receivable on the threaded portion after the pin is inserted through the aligned openings to lock the pin in the sphere.
