Abstract
Abstract A multisided building block having a cavity along each side in a peripheral zone of the block and an outwardly directed open socket held within the cavity. In an adjoining position of two building blocks, a socket belonging to one block is aligned with, and is in a close vicinity of a socket belonging to the other, adjoining block. There are further provided plugs, each conforming in shape to the socket opening and positioned within the aligned sockets for interconnecting the same.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
210 words
In a building block assembly, a building block having a foursided frame and a panel surrounded by the frame; each frame side having longitudinally extending, parallel-spaced legs and an interconnecting floor together defining an outwardly open, generally U-shaped cross section, wherein the improvement comprises in combination: a. a rib-and-shoulder formation provided on an outer zone of each leg on each side of the frame; the shoulders of the riband-shoulder formation on two adjoining sides of the frame being oriented towards one another; the shoulders of the riband-shoulder formation on the other two adjoining sides of the frame being oriented away from one another; b. a plurality of outwardly open, tubular sockets disposed centrally between the two legs of each frame side on the interconnecting floor and connected to the legs by transverse bridge members; said sockets being distributed along the length of each frame side; the distance between any adjoining two sockets in one frame side being twice the distance of an outermost socket from the adjacent end of the frame; each socket has a terminal edge that is recessed with respect to said outer edges of the legs; and c. a removable and reinsertable coupling member conforming in shape to each socket opening for being received by the socket.

Claim 3
Dependent Claim
48 words
A building block as defined in claim 1, wherein said sides consist of two long sides of equal length and two short sides of equal length, either of said long sides having a length that is an integer multiple of the length of either of said short sIdes.
Claim 4
Dependent Claim
54 words
A building block as defined in claim 1, further including oblique walls, one positioned to extend to each intersection between two adjoining sides; the outermost socket on one side and the adjacent outermost socket of an adjoining side extend at right angles to one another outwardly from one and the same said oblique wall.
Claim 5
Dependent Claim
102 words
A building block as defined in claim 1, wherein the coupling member is formed of a plurality of plugs conforming in shape to each socket opening for being received by the socket; and a web rigidly and permanently connecting said plugs with one another to define a distance therebetween that is identical to the distance between any two adjoining sockets in a frame side; said web having a width dimensioned to fit between the legs of any said frame side; said web having a thickness dimensioned to fit between the recessed terminal edges of two aligned sockets of two adjoining building blocks.
Claim 6
Dependent Claim
32 words
A building block as defined in claim 4, wherein said plugs have a tubular configuration and said web connected to said plugs surrounds about one half of the circumference of said plugs.
