Abstract
Abstract A work support table having a plurality of removable working surfaces or elements. The table may be constructed in sections joined by means such as hinges. Support surface capturing strips or lips may be mounted on each section of the table about the periphery thereof except for that edge or edges along which the section is joined to another section. When the table is folded, the removable work surfaces or elements may be installed within the lips which serve to guide and limit the movement of the work surfaces. When the table is positioned in its opened configuration, the removable work surface elements enter into abutment so that relative movement or removal of the work surface elements is impossible until the table is folded or closed again. The table may be supported by a plurality of adjustable legs so that the work surface height can be controlled at the convenience of a person standing or sitting at the table.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A table comprising a first section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, a second section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, means attaching said first and second sections at said lineal edges thereof along which said lips do not extend for movement between an abutting position and a non-abutting position, and work surface means, removably insertable into said lip means when said two planar support means are in other than an abutting relationship and adjacent lip ends of said first and second sections are not in abutment, and fixed within said lip means in abutting relationship with one another when said planar support means are in coplanar abutting relationShip and the adjacent lip ends are in abutment.
Claim 2
Dependent Claim
143 words
A table comprising a first section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, a second section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, means attaching said first and second sections at said lineal edges thereof along which said lips do not extend for movement between an abutting position and a non-abutting position, and work surface means, removably insertable into said lip means when said two planar support means are in other than an abutting relationship and adjacent lip ends of said first and second sections are not in abutment, and fixed within said lip means in abutting relationship with one another when said planar support means are in coplanar abutting relationShip and the adjacent lip ends are in abutment.
Claim 3
Dependent Claim
143 words
A table comprising a first section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, a second section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, means attaching said first and second sections at said lineal edges thereof along which said lips do not extend for movement between an abutting position and a non-abutting position, and work surface means, removably insertable into said lip means when said two planar support means are in other than an abutting relationship and adjacent lip ends of said first and second sections are not in abutment, and fixed within said lip means in abutting relationship with one another when said planar support means are in coplanar abutting relationShip and the adjacent lip ends are in abutment.
Claim 4
Dependent Claim
143 words
A table comprising a first section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, a second section having a planar support surface and a lip means about the entire periphery except for one lineal edge thereof, means attaching said first and second sections at said lineal edges thereof along which said lips do not extend for movement between an abutting position and a non-abutting position, and work surface means, removably insertable into said lip means when said two planar support means are in other than an abutting relationship and adjacent lip ends of said first and second sections are not in abutment, and fixed within said lip means in abutting relationship with one another when said planar support means are in coplanar abutting relationShip and the adjacent lip ends are in abutment.
Claim 5
Dependent Claim
23 words
The apparatus of claim 1 wherein said attaching means comprise hinge means fixing adjacent sections of said planar support surface to one another.
Claim 6
Dependent Claim
18 words
The apparatus of claim 2 including means for adjustably supporting said planar surface relative to a predetermined plane.
Claim 7
Dependent Claim
17 words
The table of claim 1 including adjustable leg means for supporting said table at a convenient height.
