Interlocking sidewalk block system

Abstract

New and improved interlocking sidewalk block system. The system incorporates a plurality of rectangular sidewalk blocks each having parallel top and bottom surfaces, parallel left length and right length side surfaces and parallel first end width and second end width surfaces. The first end width and second end width surfaces having a continuous channel running along the full width, said continuous channels being formed with lips at the first end width and second end width surfaces that create an internal height that is greater than the height at the surfaces. The system includes a plurality of couplers that are sized and shaped to have a cross section that fits simultaneously within two continuous channels when two sidewalk blocks are placed with a first end width surface of one block abutting the second end width surface of the second block and sliding a coupler into the continuous channels.

I claim the following:  
     
         1 . New and improved Interlocking Sidewalk Block System comprising: 
 a.) a plurality of rectangular sidewalk blocks each with a length dimension, a width dimension and a thickness dimension, each having a top surface, a bottom surface, a left length side surface, a right side surface, first end width side surface and a second end width side surface, the top surface being generally parallel to the bottom surface, the left length side surface being generally parallel to the right length side surface, the first end width side surface being parallel to the second end width side surface, the first end width side and second end width side surfaces both having a continuous channel running the full length of the side, said continuous channels formed by continuous openings running the full length of the first end width side and second end width side surfaces, said continuous channels each having an internal vertical dimension and an opening vertical dimension, said continuous channel opening vertical dimension is smaller than the continuous channel internal vertical dimension;    b.) a plurality of sleeves made of resilient material fixedly secured to said rectangular sidewalk block further defining said continuous channel; and    c.) a plurality of couplers that are sized and shaped with a length that approximates the width dimension of the rectangular sidewalk blocks, a cross section shape that nearly approximates the opening that is formed by the adjoining continuous channels when a first rectangular sidewalk block is placed with the first end width side surface adjacent to the second end width surface of a second rectangular sidewalk block., said couplers are further sized and shaped to permit the couplers to be slidably inserted within said adjoining continuous channels when a first rectangular sidewalk block is placed with the first end width side surface adjacent to the second end width surface of a second rectangular sidewalk block, said couplers are sized and shaped to remain frictionally secured within said adjoining continuous channels.    
     
     
         2 . New and improved Interlocking Sidewalk Block System comprising: 
 a.) a plurality of rectangular sidewalk blocks each with a length dimension, a width dimension and a thickness dimension, each having a top surface, a bottom surface, a left length side surface, a right side surface, first end width side surface and a second end width side surface, the top surface being generally parallel to the bottom surface, the first end width side surface being parallel to the second end width side surface, the first end width side and second end width side surfaces both having a continuous channel running the full length of the side, said continuous channels formed by continuous openings running the full length of the first end width side and second end width side surfaces, said continuous channels each having an internal vertical dimension and an opening vertical dimension, said continuous channel opening vertical dimension is smaller than the continuous channel internal vertical dimension;    b.) a plurality of sleeves made of resilient material fixedly secured to said rectangular sidewalk block further defining said continuous channel; and    c.) a plurality of couplers that are sized and shaped with a length that approximates the width dimension of the rectangular sidewalk blocks, a cross section shape that nearly approximates the opening that is formed by the adjoining continuous channels when a first rectangular sidewalk block is placed with the first end width side surface adjacent to the second end width surface of a second rectangular sidewalk block., said couplers are further sized and shaped to permit the couplers to be slidably inserted within said adjoining continuous channels when a first rectangular sidewalk block is placed with the first end width side surface adjacent to the second end width surface of a second rectangular sidewalk block, said couplers are sized and shaped to remain frictionally secured within said adjoining continuous channels.
