TITLE OF THE INVENTION CONSTRUCTION BLOCK BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to interconnecting blocks and more specifically to interconnecting blocks used to construct glass and glass-like partition walls, windows and the like. 2. Background of the Prior Art Glass and glass-like partition walls are a regular part of modern construction. These walls, which can be either internal or external, are made from transparent or translucent glass, or more often, plastic blocks interfitted to form the wall. The art contains numerous examples of interconnecting construction blocks, many specifically targeted for building glass and glass-like partition walls. The current preferred block for constructing partition walls is seen in U.S. patent 4,891,925 issued to Carlson et al. The Carlson block has connection means at each corner in order to join the blocks to one another. Although the Carlson device uses spacing flanges in order to assist in block alignment during wall construction, the Carlson device continues to have limitations. The connection means on the Carlson invention require a certain amount of time to fit, thereby increasing labor time during wall construction. The corner location of the

connection means reduce the tightness of the fit of the blocks to each other and increases the vulnerability of failure of block interconnection. Failure at any of the connection means will result in partition wall failure. Furthermore, the Carlson device prohibits construction of walls that have other than rectangular configurations, such as a wall or window with a sloped or curved edge. Therefore, there is a need in the art for a construction block for use in window or wall partition fabrication that overcomes the above-stated limitations. Such a device must permit rapid and efficient block interconnection. Such a block must tightly and securely interconnect to other blocks and must have connection means redundancy in case of connection means failure. The block must permit construction of partition walls and windows that are not necessarily rectangular in shape.

SUMMARY OF THE INVENTION The construction block of the present invention meets the aforementioned needs in the art. The device provides for a construction block that interconnects to another construction block almost instantaneously. The device permits part of the block to be cut away in order to permit non-rectangular-shaped partition wall construction. The failure of the connection means on the construction block of the present invention will not result in partition wall failure. The construction block of the present invention is comprised of a generally rectangular block having a pair of parallel faces joined by four side edges. A first pair of spacing flanges, perpendicular to the side edges and parallel and adjacent to the faces, are located on two of the four side edges, either on adjacent or opposing side edges. A second pair of spacing flanges, perpendicular to the side edges and parallel and adjacent to the faces, are located on two of the four side edges, either on adjacent or opposing side edges. The second pair of spacing flanges are positioned such that when one block is fitted to another block, the second pair of spacing flanges are received within the recess created by the first pair of spacing flanges of the adjacent block with the outer side faces of the second pair of spacing flanges abutting the inner side faces of the first pair of spacing flanges of the adjacent block. Each set of flanges seats upon a side edge of the

other block. The interfacing first and second pair of spacing flanges provide support for the two interconnected blocks. One or more hook receptacles are located along the lower portion of each first pair of spacing flanges. One or more resilient hooks, in corresponding number to the number of hook receptacles, are located along the length of the second pair of spacing flanges and separated from each spacing flange. Alternately, the first pair of spacing flanges can be located closer to the center of the block, and thus farther away from the faces of the block, relative to the second pair of spacing flanges. Two blocks can be positioned such that an first pair of spacing flange-bearing side edge faces a second pair of spacing flange-bearing side of the other block. Thereafter, one of the blocks is pushed into the other. The hook receptacles receive the hooks that "click" into place. One-way ramps on both the hook receptacles and the hooks assure that once the blocks are interconnected, they will not separate. Once interconnected, the top of each spacing flange abuts the side edge of the other block thereby creating a very tight, snug, and mutually supporting fit. A structural bar can be positioned between the blocks within the recess between the second pair of spacing flanges to create a further tight and snug interfit and to improve

structural integrity of any wall or window built from the blocks. Using the construction blocks of the present invention greatly expedites the construction of a partition wall. Once the blocks are positioned, they are merely snapped into place without the need to assemble any connection means. Block interfit is extremely tight and secure. By using interconnection means along the entire length of each block, as opposed to just the corners, redundancy exists in block interconnection and failure of one or more connection means will not result in partition wall or window failure. Furthermore, a section of the block may be removed, either a straight section or an arcuate section, permitting non-rectangular-shaped partition wall construction. Such block section removal will not result in block interconnection failure. The construction wall of the present invention is relatively simple and straightforward to manufacture.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings, it is seen that the construction block of the present invention, generally denoted by reference numeral 10, is a generally rectangular form, having a pair of parallel disposed faces 12 joined by four side edges 14. The block 10 may be formed as a single unit, or as shown, as a pair of identical halves 16 joined along seam 18 in any appropriate fashion. The block 10 may be formed from transparent or translucent plastic. Alternately, the block 10 can be opaque and furthermore, may be formed from any appropriate material. Several blocks 10 can be interconnected and built into a partition wall or a block window. Located on two of the side edges 14 are a first pair of spacing flanges 20 extending perpendicularly outward from the plane of the side edge 14 adjacent and parallel to each face 12. A recess 22 exists between the first pair of spacing flanges 20. The two side edges 14 that contain the first pair of spacing flanges 20 can be on adjacent side edges 14 or opposing side edges 14. As seen in figure 1, one or more hook receptacles 24 are located along the length of each first pair spacing flange 20. As seen, the hook receptacle 24 has a ramped portion 26 and a lip 28. Located on two of the side edges 14 are a second pair of spacing flanges 30 extending perpendicularly outward from the plane of the side edge 14 adjacent and parallel to each face 12. A recess 32 exists between the second pair of

spacing flanges 30. The two side edges 14 that have the second pair of spacing flanges 30 can be adjacent side edges 14, if adjacent side edges 14 hold the first pair of spacing flanges, or opposing side edges 14, if opposing side edges 14 hold the first pair of spacing flanges 20. As seen in figures 3 and 4, one or more hooks 34, in corresponding number to the number of hook receptacles 24 that are located on the first pair of spacing flanges 20 and in corresponding locations along the length of the side edges 14 relative to the locations of the hook receptacles 24, are located along the length of each second pair of spacing flange 30. As seen, each hook 34 has a ramped portion 36 and a lip 38. A small void area 40 separates the hooks 34 from the second pair of spacing flanges 30. The height of the first pair of spacing flanges 20, second pair of spacing flanges 30, and hooks 34 are all equal. The second pair of spacing flanges 30 is positioned closer to the central portion of their respective side edges 14 relative to the first pair of spacing flanges 20. As seen in figures 9-11, the first pair and second pair of spacing flanges 20 and 30 can be reversed such that the first pair of spacing flanges 20 is positioned closer to the central portion of their respective side edges 14 relative to the second pair of spacing flanges 30. In this embodiment, the hooks 34 that are across from one another now face each other and the corresponding hook receptacles 24 that are across from one another face away from each

other. In all other aspects, the structure of the block 10 remains the same. In order to interconnect two blocks 10 to one another, the blocks 10 are positioned such that a side edge 14 having the second pair of spacing flanges 30 of one of the blocks 10, faces a side edge 14 having the first pair of spacing flanges 20 of the other block 10. The two blocks 10 are pushed toward one another. This causes the ramped portion 36 of each hook 34 to interact with the ramped portion 26 of the corresponding hook receptacle 24. The hook 34 is formed such that it is sufficiently resilient to bend inwardly to permit the two ramped portions 26 and 36 to pass over one another. Once the ramped portions 26 and 36 pass one another, the hook 34 "clicks" into place and returns to its original position. As such, the lip 38 of the hook 34 abuts the lip 28 of the hook receptacle 24. The two lips 28 and 38 hold one another and prevent the blocks 10 from being separated from each other. The blocks 10 can separated from each other only by permanent invalidation of one of the blocks. In this position, the tops of the first pair of spacing flanges 20 of the first block 10 abut the side edge of the second block 10 while the tops of the second pair of spacing flanges 30 and hooks 34 of the second block 10 abut the side edge of the first block 10. This results in a secure and tight fit of the two blocks to each other. If desired, a structural bar 40 can be positioned within the second pair

of spacing flange recess 32 between the blocks after interconnecting the blocks 10 resulting in an even tighter and more secure interfit. The use of the spacing flanges assures straight and proper alignment of the blocks 10 as a partition wall is being assembled. The use of the cooperating hooks 34 and hook receptacles 24 assures a solid and sturdy interconnection of the blocks 10 that will not fail under normal conditions. Once two blocks 10 are interconnected, the overlap of each first pair of spacing flange 20 with its corresponding second pair flanges 30 can be ultrasonically welded to one another to further secure adjacent blocks 10 to each other. The outer faces of the first pair flanges 20 form a continuous grout groove. In the alternate embodiment, the second pair of spacing flanges 30 will form the grout groove. While the invention has been particularly shown and described with reference to an embodiment thereof, it will be understood by those skilled in the art that various changes in form and detail may be made without departing from the spirit and scope of the invention.
