Block pedestal having slidably supported horizontal members

1. A pedestal which comprises:

(1) a horizontal component which has:

(i) a substantially constant generally rectangular core cross-section having a horizontal width w, and a height h, w being at least 10 times h,

(ii) a horizontal dimension 1, measured at right angles to the width, which is at least 10 times h, and

(iii) a horizontal upper surface which includes a plurality of elongated, horizontally-extending configurations selected from straight open channels and straight projections;

(2) first and second vertical components, each of which has:

(i) a substantially constant, generally rectangular core cross-section,

(ii) a horizontal bottom surface comprising at least one configuration which is (a) a projecting section or (b) a recessed section, and

(iii) a horizontal top surface comprising a plurality of horizontally-elongated straight open channels,

wherein said projecting sections are received in, and horizontally slidable in, said straight open channels in the upper surface of the horizontal component, or said recessed sections receive, and are horizontally slidable over, said straight projections on the upper surface of the horizontal component, and

(3) a plurality of parallel elongated support members extending between said first and second vertical components and slidably received in the horizontally-elongated straight open channels in the horizontal top surface of said first and second vertical components;

wherein the horizontal and vertical components and support members are secured to each other only by gravitational force.

2. A pedestal according to claim 1 wherein the horizontal component has a substantially planar bottom surface.

3. A pedestal according to claim 1 wherein each of the horizontal dimension 1 and the width w is at least 20 times the height h.

4. A pedestal according to claim 1 wherein said plurality of elongated, horizontally-extending configurations are straight open channels and the first and second vertical components each comprise a projecting section which fits slidably into the straight open channel, and each straight open channel has a depth substantially equal to or less than the depth of the projecting section.

5. A pedestal according to claim 1 wherein each of the first and second vertical components has a core cross-section which is rectangular and has a width parallel to the elongated, horizontally-extending configurations of the horizontal component, and a height parallel to the height h of the horizontal component, such that the ratio of the width to the height of the core cross section of each of said first and second vertical components is from 4:1 to 40:1.

6. A pedestal according to claim 1

wherein the horizontal dimension 1 and the width w of said horizontal component is at least 20 times the height h of said horizontal component.

7. A pedestal according to claim 6 wherein, each of the horizontal dimension and the width w of said horizontal component is at least 40 times the height h of said horizontal component.

8. A pedestal comprising:

a horizontal component having a horizontal upper surface comprising an outermost horizontal perimeter and a plurality of elongated, horizontally-extending configurations selected from straight open channels and straight projections;

first and second vertical components each having:

a horizontal bottom surface comprising at least one configuration that is (a) a projecting section or (b) a recessed section; and

a horizontal top surface comprising a plurality of horizontally-elongated, straight open channels;

wherein (a) said projecting sections of the first and second vertical components are received in, and horizontally-slidable in, said straight open channels, or (b) said recessed sections of the first and second vertical components receive, and are horizontally-slidable over, said straight projections; and

the pedestal further comprises a plurality of elongated support members, each support member extending between, and supported by, said first and second vertical components by being received in one of said open channels of the first vertical component and in one of said open channels of the second vertical component;

wherein the vertical components and the support members do not extend horizontally out beyond said outermost horizontal perimeter; and

wherein the horizontal component, vertical components, and support members are secured to each other only by gravitational force.

9. A pedestal comprising:

a horizontal component having a horizontal upper surface comprising a plurality of elongated, horizontally-extending configurations selected from straight open channels and straight projections;

first and second vertical components, each having a substantially constant, generally rectangular core cross-section, a horizontal bottom surface comprising at least one configuration that is a projecting section or a recessed section, wherein said projecting sections are received in, and horizontally slidable in, said open channels, or said recessed sections receive, and are horizontally slidable over, said straight projections, and a horizontal top surface comprising a plurality of parallel, horizontally-elongated straight open channels;

a plurality of parallel, elongated support members, each support member having a first end and a second end, and each support member extending between said first and second vertical components and slidably received in the open channels of said first and second vertical components, wherein the first and second ends of each support member protrude horizontally out beyond said first and second vertical components, and

wherein the horizontal and vertical components and support members are secured to each other only by gravitational force.
