Abstract
Abstract The present invention is a device for supporting floor panels in which when the floor panels are clamped by a single-operation type panel retainer, a retaining member of a vertically swingable panel retainer support on a stud bolt is urged downwardly by the resilient force of a compression spring washer interposed between the upper surface of the retainer member and the lower surface of the head portion of the stud bolt for tightly securing the floor panels to the panel pedestal. The present invention further provides a structure for supporting floor panels in which a supporting post is swingably raised on the pedestal base plate, side walls of corners of the floor panels placed on the panel pedestal being matchingly engaged with a guide wall of the panel pedestal support and mating projections of said panel pedestal being closely fitted into mating holes formed by embedding resin holders in said floor panels, whereby the floor panels are tightly secured by a panel retainer to the panel pedester.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
122 words
A device for supporting floor panels in which a supporting post is raised on a pedestal base plate provided on a reference floor surface, the panels being placed on a panel pedestal at the upper portion of said supporting post and a single-operation type panel retainer and a panel retainer support being engaged with each other to clamp said floor panels, characterized in that a retaining member of the panel retainer support is disposed for vertical swinging movement on a collar interposed between it and a stud bolt, and that a compression spring washer for urging the retaining member downwardly is interposed between the upper surface of the retaining member and the lower surface of a head portion of the stud bolt.
Claim 2
Independent Claim
122 words
A device for supporting floor panels in which a supporting post is raised on a pedestal base plate provided on a reference floor surface, the panels being placed on a panel pedestal at the upper portion of said supporting post and a single-operation type panel retainer and a panel retainer support being engaged with each other to clamp said floor panels, characterized in that a retaining member of the panel retainer support is disposed for vertical swinging movement on a collar interposed between it and a stud bolt, and that a compression spring washer for urging the retaining member downwardly is interposed between the upper surface of the retaining member and the lower surface of a head portion of the stud bolt.
Claim 3
Dependent Claim
31 words
A device as set forth in claim 1 wherein said retaining member is raised by an inclined surface formed on the lower surface thereof of rotation relative to said panel retainer.
Claim 4
Dependent Claim
26 words
A device as set forth in claim 1 wherein a slide ring is provided between said panel retainer and said stepped portions of said floor panels.
Claim 5
Dependent Claim
139 words
A structure for supporting floor panels by a plurality of supporting devices positioned on a reference floor surface, characterized in that a pedestal base plate is fixed to said reference floor surface, that a supporting post is raised for swinging movement through an adjusting nut on said pedestal base plate, that a panel pedestal on which corner portions of said floor panels are placed is integrally formed with said supporting post at its upper portion, that a guide wall of said panel pedestal and side walls of the corners of said floor panels are brought into matching engagement with each other, and mating projections of said panel pedestal are closely fitted into mating holes formed by embedding resin holders in said floor panels, and that said floor panels are tightly secured by a panel retainer to said panel pedestal.
Claim 6
Dependent Claim
139 words
A structure for supporting floor panels by a plurality of supporting devices positioned on a reference floor surface, characterized in that a pedestal base plate is fixed to said reference floor surface, that a supporting post is raised for swinging movement through an adjusting nut on said pedestal base plate, that a panel pedestal on which corner portions of said floor panels are placed is integrally formed with said supporting post at its upper portion, that a guide wall of said panel pedestal and side walls of the corners of said floor panels are brought into matching engagement with each other, and mating projections of said panel pedestal are closely fitted into mating holes formed by embedding resin holders in said floor panels, and that said floor panels are tightly secured by a panel retainer to said panel pedestal.
Claim 7
Dependent Claim
29 words
A structure as set forth in claim 4 wherein both said guide wall of said panel pedestal and said side wall of said floor panels have the same inclination.
Claim 8
Dependent Claim
26 words
A structure as set forth in claim 4 wherein said holders are provided between said floor panels and said panel pedestal to eliminate metallic contact therebetween.
Claim 9
Dependent Claim
23 words
A structure as set forth in claim 4 wherein said mating holes of said holders are widened in direction toward its open portion.
Claim 10
Dependent Claim
25 words
