Claims
- 1. A floor section adapted for edge-to-edge connection with other similar floor sections to form a temporary extended floor surface, comprising:
- a generally planar rectangular core member plastic molded material encapsulating said core and forming edges around the rectangular floor section, each of said edges having recesses formed therein for receiving locking members, two of said edges having tongue portions formed therein and extending therealong, and the other two edges having complementary groove portions formed therein, and male-type locking members attached in two of said recesses, and complementary female locking members secured in the other two of said recesses, wherein said male and female lock members are configured to engage and automatically lock when said edges of said sections are fitted together, whereby a plurality of said floor sections can be secured in edge-to-edge relationship with said tongues and grooves and said male and female lock members in engagement with one another, respectively.
- 2. A planar section adapted for edge-to-edge connection with other similar sections, comprising:
- a panel having edges around said panel adapted for edge-to-edge connection with complementary edges of similar sections, each edge having recesses formed therein and complementary first and second locking members secured in said recesses in said edges, wherein said first and second locking members are configured so that said locking members engage and automatically lock upon fitting said sections together, whereby a plurality of said sections can be secured in edge-to-edge relationships with said complementary edges and said first and second locking members in engagement with one another, respectively.
- 3. A planar section according to claim 2, wherein said edges have complementary tongue and groove connections for securing to other planar sections having similar tongue and groove connections.
- 4. A planar section according to claim 2, wherein one half of said edges have tongue connections and one half of said edges have groove connections.
- 5. A planar section according to claim 4, wherein one half of said edges have male locking members and one half have female locking members.
- 6. A planar section according to claim 2, wherein said panel has a central core panel encapsulated in a plastic molded material, and wherein said plastic molded material forms said edges.
- 7. A planar section according to claim 2, further comprising means for disengaging said locking members when said edges are fitted together.
- 8. A planar section according to claim 2, further comprising means selectively operable for disengaging said first and second locking members.
- 9. A planar section according to claim 2, wherein the edges have an upper surface having an aperture therethrough providing access to the selectively operable means.
- 10. A planar section according to claim 2, further comprising means selectively operable to permit disengagement of said first and second locking members.
- 11. A floor section adapted for edge-to-edge connection with other similar sections, comprising:
- a panel having edges around said panel adapted for edge-to-edge connection with complementary edges of similar sections, each edge having recesses formed therein;
- complementary first and second locking members secured in said recesses, wherein said first and second locking members are configured for fitting together when said complementary edges are fitted together, and wherein said locking members are configured for engaging and automatically locking upon fitting said edges together wherein said edges remain substantially parallel and the relative approach angle of each locking member to the complementary edge of an adjacent section may be up to 45.degree. from a perpendicular approach to the complementary edge, whereby a plurality of said sections can be secured in edge-to-edge relationships with said complementary edges and said first and second locking members in engagement with one another, respectively.
- 12. A floor section as in claim 11, wherein said locking members engage when said section is pushed into a corner to engage other similar floor sections on two sides.
