Abstract

A table is disclosed having extension leaves secured to opposite edges of the table top by hinges. The hinges include a first hinge member which is secured to the leaf and a second hinge member which is connected to the table top and is slidable relative to the table top. The first and second hinge members are pivotally connected to one another by a pivot pin carried by the slidable second hinge member and received within an elongated slot of the first hinge member. A rigid stop is secured to the second hinge member and spaced away from the pivot pin a distance less than a radius from the first end of the slot to the terminal end and a distance less than a radial distance from the second end of the slot to the terminal end.

Claims

1. A table comprising:

a support (22);

a table top (24);

means for connecting said table top to said support with said top generally horizontal;

a leaf (26) for said table top;

hinge means for hinging said leaf (26) to said table top (24) with said leaf moveable between a first position generally aligned with said table top (24) and a second position extending generally upwardly from said table top, said hinge means including a first hinge member (80) secured to said leaf (26) and a second hinge member (90), slidable connecting means (110,

     104) for slidably connecting said second hinge member (90) to said table top (14), pivot means for pivotably connecting said first hinge member (80) and said second hinge member (90), said pivot means including a pivot pin (96) secured to said second hinge member (90) and a slot (88) formed in said first hinge member (80) and extending between a first end and a second end (89), said slot (88) sized to slidably and rotatably receive said pivot pin (96) with said pivot pin (96) disposed adjacent said second end (89) of siad slot (88) when said leaf (26) is in said second position;

means (100) carried on said hinge means for locking said leaf (26) in said second position including means (102) for blocking pivotal movement of said pivot pin (96) within said slot (88) when said pin (96) is adjacent said second end (89) of said slot and permitting unobstructed sliding movement of said pin toward said first end of said slot (88) with said pin rotatably within said slot (88) at said first end;

said slidable connecting means including a bracket fixedly secured to said table top, said second hinge member having means cooperating with said bracket for said second hinge member to be slidably received within said bracket, means for urging said second hinge member to slide within said bracket to a position with said pin adjustment said first end of said slot; and

said table top and said leaf present opposing edges connected by said hinge means;

said edges having opposing generally convex surfaces disposed in abutting relation whereby said leaf edge surfaces pivot on said table top edge surface and said second hinge member slides on said table top as said leaf is moved from said first position to said second position.

2. A table comprising:

a support (22);

a table top (24);

means for connecting said table top to said support with said top generally horizontal;

a leaf (26) for said table top;

hinge means for hinging said leaf (26) to said table top (24) with said leaf moveable between a first position generally aligned with said table top (24) and a second position extending generally upwardly from said table top, said hinge means including a first hinge member (80) secured to said leaf (26) and a second hinge member (90), slidable connecting means (110,

     104) for slidably connecting said second hinge member (90) to said table top (24), pivot means for pivotably connecting said first hinge member (80) and said second hinge member (90), said pivot means including a pivot pin (96) secured to said second hinge member (90) and a slot (88) formed in said first hinge member (80) and extending between a first end and a second end (89), said slot (88) sized to slidably and rotatably receive said pivot pin (96) with said pivot pin (96) disposed adjacent said second end (89) of said slot (88) when sid leaf (26) is in said second position;

means (100) carried on said hinge means for locking said leaf (26) in said second position including means (102) for blocking pivotal movement of said pivot pin (96) within said slot (88) when said pin (96) is adjacent said second end (89) of said slot and permitting unobstructed sliding movement of said pin toward said first end of said slot (88) with said pin rotatably within said slot (88) at said first end;

said slidable connecting means including a bracket fixedly secured to said table top, said second hinge member having means cooperating with said bracket for said second hinge member to be slidably received within said bracket, means for urging said second hinge member to slide within said bracket to a position with said pin adjacent said first end of said slot; and

said table is provided with two leaves on opposite sides of said table top and hinged to said table top with hinge means having second hinge members slidably connected to said table top;

second hinge members of the first leaf aligned with second hinge members of a second leaf in a plane coincident with sliding movement of said second hinge members and spring means connecting said opposing sliding members.

3. A table comprising:

a support;

a table top;

first and second extension leaves for opposing sides of said table top;

hinge means for pivotally connecting each of said first and second leaves to said table top, said hinge means including cooperating pairs of sliding hinge members and stationary hinge members, at least one of said cooperating pairs connecting each of said leaves to said table top, said stationary hinge members fixedly secured to said leaves and having tongues with elongated slots therein, said slots hvaing longitudinal dimensions extending between first and second slot ends;

said sliding hinge members each having a pivot pin connected thereto;

slidable connecting means for connecting said sliding hinge members to said table top with said pivot pins slidable between first and second positions, said pivot pins in said first position being disposed beneath said table top, said pins in said second position being disposed spaced from an edge of said table top, said slidable connecting means including a bracket fixedly secured to said table top, said sliding hinge members including means cooperating with said bracket for said sliding hinge members to be slidably received within said bracket, means for urging said sliding hinge members to slide within said bracket to a position with said pivot pins in said first position;

said pins sized to be slidably and rotatably received within said slots;

said pins slidable between said first and second ends of said slots and with said pins adjacent said second ends when said leaves are pivoted to a position extending generally perpendicularly upwardly from said table top;

rigid stop means secured to said sliding hinge members and disposed to abut said stationary hinge members and block relative rotation between said pins and stationary hinge members when said pins are adjacent said second ends of said slots; and

means for pivotally mounting said table top on said support comprising horizontal spaced-apart stationary slide elements supported by said support;
