Abstract
A system for positioning and maintaining in place an horizontal plate upon an horizontal surface such as the upper face of a rest block, typically when such plate and such block are elements of a modular furniture system, characterized in that the components of said positioning system are not visible on any of said plate surfaces, which enables said plate to be reversible.
Claims8
A fastener system for positioning and maintaining in place a horizontal plate upon a horizontal support surface, wherein the horizontal plate has top and bottom planar surfaces and a peripheral edge having a recess containing a hole, and the support surface has an upper horizontal surface containing first and second holes, said fastener comprising:
- a shoe mountable on the upper horizontal surface of the support surface, said shoe having a horizontal upper bearing plate, a horizontal lower base plate, and a middle connecting portion connecting said lower base plate to said upper bearing plate, said lower base plate having a first stud extending downwardly therefrom aligned and configured to fit into the first hole of the support surface and a second stud extending downwardly therefrom aligned and configured to fit into the second hole of the support surface, said middle connecting portion having two vertical parallel sides defining with said upper bearing plate and said lower base plate a pair of grooves parallel to each other and to said horizontal surface of said support surface;
- and
- a movable fork having horizontal arms slidably engageable with said grooves of said shoe, a rear body extending perpendicularly from said arms, said rear body having a vertical semi-cylindrical heel having a planar rear face having a height equal to the thickness of said plate, a front face slidably connectable with said recess of said peripheral plate edge, and a stud extending perpendicularly from said front face, said stud being slidably connectable with said hole in said plate edge recess.
A reversible modular furniture system comprising:
- a plate having top and bottom planar surfaces and a peripheral edge having a recess containing a hole;
- a support surface having an upper horizontal surface containing first and second holes;
- and a fastener system for removably connecting said plate to said support surface with either said top planar surface or said bottom planar surface facing said support surface, said fastener system comprising:
- a shoe mountable on said upper horizontal surface of said support surface, said shoe having a horizontal upper bearing plate, a horizontal lower base plate, and a middle connecting portion connecting said lower base plate to said upper bearing plate, said lower base plate having a first stud extending downwardly therefrom aligned and configured to fit into said first hole of said support surface and a second stud extending downwardly therefrom aligned and configured to fit into said second hole of said support surface, said middle connecting portion having two vertical parallel sides defining with said upper bearing plate and said lower base plate a pair of grooves parallel to each other and to said horizontal surface of said support surface;
- and
- a moveable fork having horizontal arms slidably engageable with said grooves of said shoe, a rear body extending perpendicularly from said arms, said rear body having a vertical semi-cylindrical heel having a planar rear face having a height equal to the thickness of said plate, a front face slidably connectable with said recess of said peripheral plate edge, and a stud extending perpendicularly from said front face, said stud being slidably connectable with said hole in said plate edge recess.
