Abstract
Abstract Interlocking sections for portable floors and the like have a floor section (10) having interlocking members set in molded urethane (15) for connections along the edges of the floor sections (10). The interlocking members latch a male member (50) and a female member (70) fitting into recesses along the edges of the floor section (10) and are molded into place. The female locking member (70) has a central slot (85) receiving a flange (60) of the male locking member (50). Slots (81a, 81b) and (100a, 100b) and springs (90, 91) guide motion of pins (80a, 80b) which engage the flange (60). A release mechanism (120) actuated by an Allen key wrench has a cam member (121) which engages the springs (90, 91) to release the male locking member (50).

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
152 words
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.
Claim 2
Dependent Claim
152 words
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.
Claim 3
Dependent Claim
101 words
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.
Claim 4
Dependent Claim
101 words
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.
Claim 5
Dependent Claim
28 words
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.
Claim 6
Dependent Claim
25 words
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.
Claim 7
Dependent Claim
24 words
A planar section according to claim 4, wherein one half of said edges have male locking members and one half have female locking members.
Claim 8
Dependent Claim
30 words
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.
Claim 9
Dependent Claim
21 words
A planar section according to claim 2, further comprising means for disengaging said locking members when said edges are fitted together.
Claim 10
Dependent Claim
20 words
A planar section according to claim 2, further comprising means selectively operable for disengaging said first and second locking members.
Claim 11
Dependent Claim
25 words
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.
Claim 12
Dependent Claim
22 words
A planar section according to claim 2, further comprising means selectively operable to permit disengagement of said first and second locking members.
Claim 13
Dependent Claim
146 words
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° 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.
