Abstract

A table surface member is movable between a vertical storage position against a wall and a usable positioned horizontally extending from the wall. The table member connects to the wall by means of a hinge assembly which permits folding of the table such that the upper edge of the table in the storage position is the edge adjacent the wall in the usable position. In a preferred embodiment latch means are provided for latching the edge of the table to the wall or wall mounting bracket in the usuable position, so that no supporting legs for the outer end of the table are required. Alternatively, another disclosed embodiment uses folding legs to support the outer edge of the table in the usuable position. A preferred hinge assembly includes upper and lower hinge arms pivotally connecting to the wall and the table. The pivotal axis of the lower arm or arms to the table is spaced below a plane passing through the pivot axis of the upper arm to the table and parallel with the table surface. This offset plus intentional length mismatching of the hinge arms provides an overcenter resistance force which holds the table in its storage position without the need for a separate latch or counterbalance.

Claims

1. A folding wall table adapted for attachment to a wall for movement between a storage position vertically disposed adjacent the wall and a usable position horizontally extending from the wall, comprising:

a table surface member;

a wall mounting plate for attachment to a wall;

hinge means connecting said table surface member to said wall mounting plate for movement between said usable and storage positions so that the inner edge of the table, nearest the wall in the usable position, is the uppermost edge in the storage position; and

first and second latch means connected respectively to said table surface member adjacent said inner edge thereof and to said wall mounting plate, said latch means for securing said inner edge of said table surface to said wall mounting plate when the table is in its usable position.

2. A folding table according to claim 1 wherein said first latch means includes a pair of latch bolt assemblies secured to the underside of the table surface member adjacent the inner edge.

3. A folding table according to claim 2 wherein said second latch means includes striker plates connected to said wall mounting plate and wherein said latch bolts engage said striker plates.

4. A folding table according to claim 1 further including latch release means positioned adjacent the outer end of the table and operatively connected to said first latch means for actuation thereof.

5. A folding wall table adapted for attachment to a wall for movement between a storage position vertically disposed adjacent the wall and a usable position horizontally extending from the wall, comprising:

a table surface member;

upper and lower hinge arm means;

upper and lower wall pivot means for pivotally connecting said upper and lower hinge arm means respectively to said wall with the pivot axis of said upper hinge arm means higher than the pivot axis of said lower hinge arm means;

upper and lower table pivot means for pivotally connecting said upper and lower hinge arm means respectively to the underside of said table surface member with the pivot axis of said upper table pivot means positioned closer to the wall, when the table is in its usable position, than the pivot axis of said lower table pivot means;

said hinge arm means and said pivot means for allowing movement of said table surface member between its usable and its storage positions with the underside of the table folding against the wall in the storage position;

the pivot axis of said lower table pivot means being spaced below a plane passing through the pivot axis of said upper table pivot means and parallel with the table surface when in its usable position, so as to provide an overcenter resistance force to the movement of the table through an intermediate position near the storage position; and

latch means attached to the underside of said table surface member adjacent the edge thereof closest to the wall in the usable position, for securing said table in its usable position.

6. A folding wall table according to claim 5 wherein said wall pivot means includes a wall plate having striker plate means for cooperating with said latch means.

7. A folding wall table according to claim 6 further including latch release means positioned near the opposite end of the table surface member from the latch means, and means operatively connecting the release means for unlatching the table.

8. A folding wall table according to claim 5 wherein said upper hinge arm means comprises a pair of arms made of metal tubing.

9. A folding wall table according to claim 8 wherein said lower hinge arm means comprises a single relatively rigid arm, and wherein said lower table pivot includes a resilient tubular member pivoted to the table at its ends and connected to the end of the lower hinge arm at its center, whereby the resilient tubular member deflects to absorb the overcenter resistance force.

10. A folding wall table according to claim 8 wherein the effective length of said lower hinge arm is longer by a predetermined amount than the effective length of said upper hinge arm means plus the distance between said upper and lower wall pivot means minus the distance between said upper and lower table pivot means, so as to preload said resilient tubular member when the table is in its vertical storage position.
