Total Claims: 10
Claim 1
Independent Claim
152 words
A chair comprising a pair of side frames having sidearm portions, back frame means interconnecting said side frames, seat means extending between said side frames, a table member, and a of elongated coacting members having combined relative slidable and rotary movement, one of said pair of members being pivotally mounted at one thereof to a rear portion of one of said side frames, means for mounting said table member on the other of said pair of members, whereby said table member may be swung upwardly in a vertical plane from a vertical storage position adjacent said one frame to a position above the sidearm portions of said side frames, thence rotated about the axes of said pair of members to a horizontal position overlying and supported by the sidearm portions of said side frames and movable in a horizontal plane to selected positions relative to said sidearm portions of the side frames.
Claim 2
Dependent Claim
152 words
A chair comprising a pair of side frames having sidearm portions, back frame means interconnecting said side frames, seat means extending between said side frames, a table member, and a of elongated coacting members having combined relative slidable and rotary movement, one of said pair of members being pivotally mounted at one thereof to a rear portion of one of said side frames, means for mounting said table member on the other of said pair of members, whereby said table member may be swung upwardly in a vertical plane from a vertical storage position adjacent said one frame to a position above the sidearm portions of said side frames, thence rotated about the axes of said pair of members to a horizontal position overlying and supported by the sidearm portions of said side frames and movable in a horizontal plane to selected positions relative to said sidearm portions of the side frames.
Claim 3
Dependent Claim
34 words
A chair as in claim 1 wherein said pair of members are in telescopic relation, one of said telescopically related members being pivotally mounted at the outer end thereof on said one side frame.
Claim 4
Dependent Claim
28 words
A chair as in claim 2, wherein the other of said telescopically related members is mounted on the underside of said table member adjacent one side edge thereof.
Claim 5
Dependent Claim
87 words
A chair as in claim 1, and further including means for preventing inadvertent swinging movement of said table member relative to said one side frame, said means comprising separable, interengaging coacting members respectively mounted on said one side frame and said table member and operative to prevent swinging movement of said table member when said table member is subjected to one mode of movement thereof, and to allow for swinging movement of said table member when said table member is subjected to another mode of movement thereof.
Claim 6
Dependent Claim
63 words
A chair as in claim 4 wherein said separable coacting members include a locking plate affixed to said one side frame, said plate having an inclined, upwardly opening slot, and a pin member projecting from the movable member mounted on said table member, said pin member being receivable in the slot of said plate when said table member is in its storage position.
Claim 7
Dependent Claim
55 words
A chair as in claim 3 wherein said telescopically related members are longitudinally adjustable to locate said table member in selected positions relative to said back frame means, and coacting movable means on the sidearm portion of one of said side frames and said table member for locking said table member in selected positions thereof.
Claim 8
Dependent Claim
67 words
A chair as in claim 1 and further including footrest means, a pair of horizontally disposed tubular members fixed to the lower ends of the respective side frames, members telescopically mounted in said pair of tubular members, bracket means interconnecting the forward ends of the telescopically mounted members, means for movably mounting said footrest means on said bracket means for movement between operative and inoperative positions thereof.
Claim 9
Dependent Claim
52 words
A chair as in claim 7 and further including caster means mounted on the lower ends of said side frames, said bracket means including depending stabilizer means in inwardly offset relation to said caster means, the stabilizer means terminating in a plane slightly above the plane of movement of said caster means.
Claim 10
Dependent Claim
40 words
A chair as in claim 6 and further including coacting means respectively mounted on said telescopically related members to (1) limit the longitudinal displacement of the telescopically related members, and (2) to allow said telescopically related members to be separated.
