Abstract
An elevated floor board comprising an upper and a lower floor board combined together by means of combining posts on the upper board and cylindrical posts on the lower board fitting with the combining posts, a number of hard gasket rings and soft gasket rings disposed to fit around the combining post to adjust the height of the elevated floor board, one or two separating boards possible to be fixed between the upper and the lower floor board to form two or more cavities between the upper board, the lower board and the separating board(s) for dispose electric or telephone lines to prevent mutual interference.
Claims12
An elevated floor board comprising:
- an upper floor board provided with a plurality of combining posts extending downward from four corners;
- a lower floor board having essentially the same size and shape as said upper floor board, the lower floor board including a plurality of receiving posts extending upward from four corners to receive said combining posts of said upper floor board in center holes thereof, each of said receiving posts having two different diameters, an upper segment with a small diameter and a lower segment with a large diameter;
- at least one separating board disposed between said upper and said lower floor boards, the separating board having essentially the same size and shape as said upper and lower boards, the separating board having holes to fit around the upper small segment of each receiving post of said lower floor board;
- a plurality of gasket rings to fit around each of said combining posts of said upper floor board, at least one of said gasket rings on each combining post being formed from an elastic material so as to absorb shock and sound when the floor is stepped on;
- and
- said gasket rings being disposed between the upper floor board and the lower floor board, fitting around said combining posts of said upper floor board,
- each segment of the floor being assembled by placing said combining posts through said gasket rings, thence through said holes in said separating board, where the combining posts are received in the receiving posts of said lower floor board,
- the number of said gasket rings being changed to alter the height of the elevated floor board, said separating board forming an upper cavity between itself and the board above it and a lower cavity between itself and the board below it for disposing electric wires or telephone lines therein to protect said wires or lines and to prevent mutual interference.

An elevated floor board comprising:
- an upper floor board having a plurality of combining posts extending down from four corners;
- a lower floor board having essentially the same size and shape as said upper floor board and a plurality of receiving posts extending up from four corners, each of said receiving posts having a through hole;
- a plurality of gasket rings, each having a hole just large enough to fit around a combining post of said upper floor board, at least one of said gasket rings on each combining post being formed from an elastic material so as to absorb shock and sound when the floor is stepped on;
- said combining posts of said upper floor board passing through said gasket rings where they are received into said receiving posts of said lower floor board, thereby forming a cavity between said upper and said lower floor boards, with said gasket rings fitting around said combining posts, said combining posts fitting in said receiving posts, the number of said gasket rings being changed to alter the height of the elevated floor board.

An elevated floor board comprising:
- an upper floor board having a plurality of combining posts extending downward;
- a lower floor board having essentially the same size and shape as said upper floor board and a plurality of receiving posts extending upward, each of said receiving posts having a center combining hole to receive said combining posts of said upper floor board;
- a plurality of gasket rings, each having a hole just large enough to fit around said combining posts of said upper floor board, at least one of said gasket rings on each combining post being formed from an elastic material so as to absorb shock and sound when the floor is stepped on;
- and
- a plurality of locating bases disposed between each two neighboring receiving posts of said lower floor board, each said locating base having two curved walls fixed at two ends of a straight flat wall to fit around each said receiving post, said flat wall being provided with electric or telephone sockets or other electrical components.
