Translucent building blocks

Claim 2

In an article of manufacture in the form of a hollow translucent block having substantially vertical and substantially parallel side walls connected to substantially vertical and substantially parallel end walls, said side walls being longer than said end walls, said side walls and said end walls being connected to a bottom wall, the improvement comprising said bottom wall being defined by at least two oblique portions each forming an acute angle with respect to said side walls, said oblique portions having smooth upper and lower surfaces, said oblique portions converging to a ridge within said block, each side wall cooperating with the adjacent one of said oblique portions to form first and second trough portions, at least one of said trough portions being at least partially filled with a transparent liquid such that said liquid cooperates with the oblique portions with which it is in contact to transmit at least some light incident on said side walls through said block by total internal reflection and refraction.

Claim 3

The improvement of claim 1 wherein said ridge is substantially parallel to said side walls of said block.

Claim 4

A window structure including at least two of the translucent blocks of claim 1 in superposed relation.

Claim 5

The improvement of claim 1, wherein said transparent liquid is coloured.

Claim 6

The improvement of claim 1, wherein said transparent liquid is water.

Claim 7

The improvement of claim 1, further comprising a coloured gas in any volume left vacant by the liquid.

Claim 8

In an article of manufacture in the form of a hollow translucent block having substantially vertical and substantially parallel side walls connected to substantially vertical and substantially parallel end walls, said side walls being longer than said end walls, said side walls and said end walls being connected to a bottom wall, the improvement comprising said bottom wall being partially defined by a horizontal flange portion substantially perpendicular to said side walls and said end walls, and extending inwardly from said side walls and said end walls, and said bottom wall being partially defined by a hollow, depending portion having the shape of a right triangle, wherein a side wall of said depending portion lies in a plane substantially parallel to one of said side walls of said block and is connected to said flange portion, the end walls of said depending portion lie in a plane substantially parallel to the end walls of said block and are connected to said flange portion and wherein the other wall of said depending portion comprising a hypotenuse forms an oblique angle with said side wall of said depending portion by being connected at its lower end to said side wall of said depending portion and connected at its upper end to said flange portion, all of said walls and said hypotenuse having smooth surfaces, and said depending portion being at least partially filled with a liquid such that said liquid cooperates with said hypotenuse to transmit at least some light incident on said side walls of said block and said depending portion through said block by total internal reflection and refraction.

Claim 9

In an article of manufacture in the form of a hollow translucent block having substantially vertical and substantially parallel side walls connected to substantially vertical and substantially parallel end walls, said side walls being longer than said end walls, said side walls and said end walls being connected to a bottom wall, the improvement comprising said bottom wall being partially defined by a horizontal flange portion substantially perpendicular to said side walls and said end walls, and extending inwardly from said side walls and said end walls, and said bottom wall being partially defined by a hollow, depending portion having the shape of a right triangle, wherein a side wall of said depending portion lies in a plane substantially parallel to one of said side walls of said block and is connected to said flange portion, the end walls of said depending portion lie in a plane substantially parallel to the end walls of said block and are connected to said flange portion and wherein the other wall of said depending portion comprising a hypotenuse forms an oblique angle with said side wall of said depending portion by being connected at its lower end to said side wall of said depending portion and connected at its upper end to said flange portion, all of said walls and said hypotenuse having smooth surfaces, and said depending portion being at least partially filled with a liquid such that said liquid cooperates with said hypotenuse to transmit at least some light incident on said side walls of said block and said depending portion through said block by total internal reflection and refraction.

Claim 10

A window structure including at least two of the blocks of claim 7 in superposed relation.

Claim 11

A window structure comprising at least two superimposed translucent blocks, each of said blocks having substantially vertical and substantially parallel first and second walls connected to substantially vertical and substantially parallel third and fourth walls, said first and second walls being longer than said third and fourth walls, said walls being connected to a fifth wall, said fifth wall being defined by at least two oblique portions each forming an acute angle with respect to said first and second walls, said oblique portions having smooth upper and lower surfaces, said oblique portions converging to a ridge within said block, the cross-section of said blocks being W-shaped when said blocks are in a first position and M-shaped when said blocks are in a second position inverted from said first position, said blocks being at least partially filled with a transparent liquid which cooperates with said oblique portions with which said liquid is in contact to transmit at least some light incident on said first and second walls through said block by total internal reflection and refraction.

Claim 12

A window structure comprising at least two superimposed translucent blocks, each of said blocks having substantially vertical and substantially parallel first and second walls connected to substantially vertical and substantially parallel third and fourth walls, said first and second walls being longer than said third and fourth walls, said walls being connected to a fifth wall, said fifth wall being defined by at least two oblique portions each forming an acute angle with respect to said first and second walls, said oblique portions having smooth upper and lower surfaces, said oblique portions converging to a ridge within said block, the cross-section of said blocks being W-shaped when said blocks are in a first position and M-shaped when said blocks are in a second position inverted from said first position, said blocks being at least partially filled with a transparent liquid which cooperates with said oblique portions with which said liquid is in contact to transmit at least some light incident on said first and second walls through said block by total internal reflection and refraction.
