Abstract
Abstract A table assembly which may be repeatedly manufactured with identical components, but which may be sold in different lengths. Each side of the table includes a pair of spaced female beam members interconnected by a male beam member having its opposite ends disposed within the opposed female beam members. The male and female beam members are four sided and there are a set of four pads disposed at each end of the male beam member and a set of four pads disposed at the distal ends of the female members for supporting the male beam member centrally within the female beam members and so that the male beam member may slide relative to the female beam members. Associated with each set of four pads is a pair of spaced plates having notches in opposite extremities thereof so that a pair of the pads have their ends disposed in the notches whereas the remaining two pads are supported by the plates themselves. If the customer desires the table to be of an extended length, the female beam members are pulled apart to expose the interconnecting male beam members and a cover member is disposed over the exposed portion of the male beam members. The table also includes a flange means secured to the beam members for supporting a table top.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
188 words
A table assembly comprising; an extensible frame means including a plurality of legs supporting interconnected beams and including at least one hollow female beam member and at least one male beam member, said male beam member having a first end slidably disposed in said female beam member and extending from a first end of said female beam member, said male beam member being smaller in exterior cross section than the interior cross section of said female beam member, and separate support means disposed between said members for supporting said male beam member centrally within and spaced from the interior of said female beam member, said support means including first independent pad means attached to the interior of said female beam member adjacent and wholly within said first end of said female beam member and second independent pad means attached to said male beam member adjacent the first end of said male beam member which is disposed within said female beam member, said male and female beam members being multi-sided, said first and second pad means each including a set of pads with one for each of said sides.
Claim 2
Dependent Claim
188 words
A table assembly comprising; an extensible frame means including a plurality of legs supporting interconnected beams and including at least one hollow female beam member and at least one male beam member, said male beam member having a first end slidably disposed in said female beam member and extending from a first end of said female beam member, said male beam member being smaller in exterior cross section than the interior cross section of said female beam member, and separate support means disposed between said members for supporting said male beam member centrally within and spaced from the interior of said female beam member, said support means including first independent pad means attached to the interior of said female beam member adjacent and wholly within said first end of said female beam member and second independent pad means attached to said male beam member adjacent the first end of said male beam member which is disposed within said female beam member, said male and female beam members being multi-sided, said first and second pad means each including a set of pads with one for each of said sides.
Claim 3
Dependent Claim
47 words
An assembly as set forth in claim 1 wherein at least one of said pad means includes a pair of spaced plates with notches in opposite extremities thereof and a pair of pads with the ends of each pad disposed in said notches of the spaced plates.
Claim 4
Dependent Claim
67 words
An assembly as set forth in claim 1 wherein said frame means includes a second female beam member, said male beam member having a second end disposed within and extending from a first end of said second female beam member whereby the distance between said first ends of said first and second female beam members may be varied by sliding said beam members relative to one another.
Claim 5
Dependent Claim
17 words
An assembly as set forth in claim 1 including positioning means interconnecting said pads of each set.
Claim 6
Dependent Claim
119 words
An assembly as set forth in claim 4 wherein said positioning means includes a pair of spaced plates for each set of pads, said plates having notches in opposite extremities thereof, a first pair of said pads each having their opposite ends disposed in said notches of said spaced plates, said plates each having one of said other pads supported thereby. 6 An assembly as set forth in claim 3 wherein said first and second female beam members are spaced apart whereby an intermediate portion of said male beam member is exposed and including a cover member for disposition over the exposed portion of said male beam member between the spaced apart first ends of said female beam members.
Claim 7
Dependent Claim
43 words
An assembly as set forth in claim 6 wherein said cover member includes spacer means at each end thereof for engaging said male beam member whereby the outer periphery of said cover is contiguous with the outer peripheries of said female beam members.
Claim 8
Dependent Claim
145 words
A table assembly comprising: an extensible frame means including two parallel and spaced sets of first and second female beam members and two male beam members, cross beam members extending between laterally spaced pairs of said female beam members, and leg means extending downwardly from said beam members for supporting same; each of said first female beam members being disposed in longitudinal spaced relationship with one of said second female beam members; each of said male beam members having a first end disposed in one of said first female beam members and a second end disposed in one of said second female Members with an intermediate portion of each of said male beams members being exposed between the spaced ends of said first and second female beam members; and a pair of cover members disposed over the exposed intermediate portions of said male beam members.
Claim 9
Dependent Claim
145 words
A table assembly comprising: an extensible frame means including two parallel and spaced sets of first and second female beam members and two male beam members, cross beam members extending between laterally spaced pairs of said female beam members, and leg means extending downwardly from said beam members for supporting same; each of said first female beam members being disposed in longitudinal spaced relationship with one of said second female beam members; each of said male beam members having a first end disposed in one of said first female beam members and a second end disposed in one of said second female Members with an intermediate portion of each of said male beams members being exposed between the spaced ends of said first and second female beam members; and a pair of cover members disposed over the exposed intermediate portions of said male beam members.
