Abstract
Abstract This invention, entitled "dual position table top support" permits a table top to be supported in a horizontal working position or in a vertical out-of-the way storing position. The support is such that it is to be installed in an area bounded by three adjacent walls without having to fasten it physically, i.e. by means of screws, nails, rivets, adhesive, to any wall. It is intended for use in locations where a free-standing support or a support physically fastened to a wall is impractical. It is particularly suited for installation over a bathtub to provide a utility table suitable for hobbyists such as amature photographers who use their bathroom as a temporary darkroom.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
129 words
A table support assembly for use in conjunction with an alcove having a pair of side walls and an end wall comprising: a pair of side frame members adaptable to be mounted in spaced relationship in abutment with the respective side walls and at least one compression member disposed perpendicularly between said side frame members and closely adjacent to said end wall and sized to press said side frame members against the respective side walls, each of said side frame members having an upper surface for receiving a table top in flat mounted position resting thereon and also having an elongated cut-out in the rear edge for receiving the table between said side frame members and said end wall in upright stored position substantially parallel to said end wall.
Claim 2
Dependent Claim
129 words
A table support assembly for use in conjunction with an alcove having a pair of side walls and an end wall comprising: a pair of side frame members adaptable to be mounted in spaced relationship in abutment with the respective side walls and at least one compression member disposed perpendicularly between said side frame members and closely adjacent to said end wall and sized to press said side frame members against the respective side walls, each of said side frame members having an upper surface for receiving a table top in flat mounted position resting thereon and also having an elongated cut-out in the rear edge for receiving the table between said side frame members and said end wall in upright stored position substantially parallel to said end wall.
Claim 3
Dependent Claim
21 words
A table support assembly as defined in claim 1 wherein each of said side frame members has an enlarged central cut-out.
Claim 4
Dependent Claim
74 words
A table support assembly as defined in claim 2 wherein facing surfaces of said side frame members closely adjacent to said end wall slope towards each other in the downward direction and said compression member includes opposite ends which are parallel to and abut the respective facing side frame slopes, whereby said compression member forces said side members apart and into abutment with said side walls respectively as said compression member is forced downwardly.
Claim 5
Dependent Claim
34 words
A table support assembly as defined in claim 3 wherein said compression member support surfaces include mating grooved surfaces to prevent lateral motion between said compression member surfaces and said side frame member surfaces.
Claim 6
Dependent Claim
54 words
A table support assembly as defined in Claim 1 wherein said side frame members are respectively provided with wall contactors for contacting said alcove sidewalls outside of the lines of action of the forces of the compression member on the side members and base contactors at the bottom edges of said side frame members.
Claim 7
Dependent Claim
53 words
A support as defined in claim 1 including a plurality of said compression members and in which facing surfaces of said side frame members closely adjacent to said end wall are vertical and each of said compression members includes at least one threaded screw type device for adjustment of length and compressive force.
Claim 8
Dependent Claim
27 words
A compression member as defined in claim 6 in which at least one piece of each of said compression members is permanently attached to a side member.
Claim 9
Dependent Claim
42 words
A support as defined in claim 6 in which the compression member support surfaces on said side frames and the contacting surfaces of the compression members include recessions and mating protrusions to prevent motion normal to the axis of the compression member.
Claim 10
Dependent Claim
49 words
A support as defined in claim 1 including a plurality of said compression members in which facing surfaces of said side frame members closely adjacent to said end wall are vertical and each of the compression members includes a spring loaded device for adjustment of length and compressive force.
Claim 11
Dependent Claim
27 words
A compression member as defined in claim 9 in which at least one piece of each of said compression members is permanently attached to a side member.
Claim 12
Dependent Claim
42 words
A support as defined in claim 9 in which the compression member support surfaces on said side frames and the contacting surfaces of the compression members include recessions and mating protrusions to prevent motion normal to the axis of the compression member.
Claim 13
Dependent Claim
20 words
A support as defined in claim 1, in which said compression member is integrally joined to said side frame members.
