Abstract
Abstract A slide device for supporting the folding leaf of a dropleaf table comprises a bar and an elongated retainer having a channel which receives the bar for lengthwise reciprocation. The channel has a depth slightly greater than the width of the bar, and the retainer is provided with oppositely extending coplanar flanges on opposite sides of the channel which define a substantially flat mounting surface. A first boss is provided on each flange near one end which projects above the mounting surface. A second boss of substantially the same height as the first boss is also provided on each flange and is disposed adjacent to the first boss on the side thereof toward the other flange end. Each second boss has a first mounting hole therethrough, and each flange is provided with a second mounting hole near the other end thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
189 words
A slide device for supporting the folding leaf of a drop-leaf table comprising an elongated bar, an elongated retainer channel having opposite ends which receives said bar for lengthwise reciprocation, said channel having oppositely extending coplanar flanges on opposite sides thereof which define a substantially flat mounting surface adapted to mount said channel on the underside of a tabletop, said bar having an upper surface spaced below said mounting surface, a first boss on each flange near one end of said channel which projects above said mounting surface, a second boss of substantially the same height above said surface as said first boss on each flange and disposed adjacent to said first boss on the side thereof toward the other end of said channel, each second boss having a first mounting hole therethrough and each said flange having a second mounting hole near said other end of said channel, said bar being movable between a retracted position substantially within said channel and an extended position extending outwardly from said other end of said channel for supporting the folding leaf in a horizontal position generally aligned with said table top.
Claim 2
Dependent Claim
189 words
A slide device for supporting the folding leaf of a drop-leaf table comprising an elongated bar, an elongated retainer channel having opposite ends which receives said bar for lengthwise reciprocation, said channel having oppositely extending coplanar flanges on opposite sides thereof which define a substantially flat mounting surface adapted to mount said channel on the underside of a tabletop, said bar having an upper surface spaced below said mounting surface, a first boss on each flange near one end of said channel which projects above said mounting surface, a second boss of substantially the same height above said surface as said first boss on each flange and disposed adjacent to said first boss on the side thereof toward the other end of said channel, each second boss having a first mounting hole therethrough and each said flange having a second mounting hole near said other end of said channel, said bar being movable between a retracted position substantially within said channel and an extended position extending outwardly from said other end of said channel for supporting the folding leaf in a horizontal position generally aligned with said table top.
Claim 3
Dependent Claim
22 words
