Abstract:
1. An endless track comprising: a plurality of detachable adjacent links, each comprising a main body with inwardly and outwardly facing surfaces, a male linking end, and an opposite female linking end; and wherein the male linking end protrudes from the main body, and the female linking end includes a receiving station, and wherein the receiving station of a first link releasably matingly couples with the male linking end of a second adjacent link when the angular relationship as measured between the outwardly facing surfaces of the first and second links are oriented at an angle of less than about 110 degrees; and wherein the male linking end of the second link freely rotates within the receiving station of the first link without detaching from the first link when the angular relationship as measured between the outwardly facing surfaces of the first and second links is at an angle of greater than about 110 degrees, and wherein the main body is defined by x, y, and z axes, and wherein the male linking end is substantially coaxially aligned relative to the y axis; and wherein the at least one receiving cavity is oriented substantially parallel to the x axis; and wherein the at least one receiving cavity further comprises a first cavity having a width dimension which is measured in a direction which is substantially parallel to the y axis; and a second cavity that is coupled to the first cavity and which extends in the direction of the inwardly facing surface of the main body, and which is further oriented in substantially parallel relation relative to the z axis; and wherein the second cavity has a length and a width dimension; and wherein the receiving station is substantially coaxially oriented relative to the y axis; and wherein the at least one post is oriented in substantially parallel relation relative to the x axis, and further has a length dimension when measured in a direction which is substantially parallel to the y axis, and a width dimension when measured in a direction which is substantially parallel to the z axis; and wherein the length dimension of the post is greater than the width dimension thereof; and wherein the width dimension of the first cavity is greater than the width dimension of the post, and is less than the length dimension of the post; and wherein the length and width dimensions of the second cavity are greater than the length dimension of the post; and wherein the post of the first link enters the first cavity of the second adjacent link when the angular relationship between the first and second links, as measured between the outwardly facing surfaces thereof lies in a range of greater than about 45 degrees to less than about 110 degrees; and wherein the post of the first link enters the second cavity of the second adjacent link such that the post and the second cavity are substantially coaxially aligned and oriented in substantially parallel spaced relation relative to the x axis; and wherein the first and second links substantially freely rotate, one relative to the other when the angular relationship between the first and second links, as measured between the outwardly facing surfaces, lies in a range of greater than about 110 degrees to less than about 270 degrees, and wherein the plurality of adjacent links are fabricated of a moldable, castable, or machinable material.
