Sleeper sofa
A convertible sofa-bed which is easy to convert between a sofa configuration and a bed configuration is provided. From a sofa configuration, a buttock-foot member may be pulled outward. Simultaneously, a head rest member and back rest member which are initially at a generally vertical position are traversed to a generally horizontal position. When the buttock-foot member is fully traversed outward (i.e., extended position), the head rest member, back rest member and the buttock-foot member are generally substantially coplanar and generally horizontal. This provides a firm bed. From the bed configuration, head rest member and the back rest member may be buckled to allow the buttock-foot member to be pushed inward. The buttock-foot member is then pushed fully inward (i.e., retracted position) until the head rest member and the back rest member are in the generally vertical position with the buttock-foot member and back rest member forming a seat.
1. Convertible furniture comprising:
a base frame comprising;
at least one frame member positioned in general horizontal relation to supporting floor surface and including a cross-bar positioned in general horizontal relation to the floor surface;
at least one support member interconnected to said cross-bar, said support member defining a contacting surface; and
an articulating assembly comprising:
a quadrangle headrest member having opposed lateral side members and opposed longitudinal side members;
as quadrangle backrest member having opposed lateral side members and opposed longitudinal side members; and
a quadrangle foot member further having opposed lateral side members and opposed longitudinal side members;
the headrest, backrest and foot members being connected to each other such that the articulating assembly is selectively movable between a first position wherein the headrest, backrest and foot members extend in generally co-planer relation to each other, and a second position wherein the headrest and backrest member each extend at a particular angular relation to the foot member; and
the articulating assembly and the base frame being oriented relative to each to each other such that the movement of the of the articulating assembly to the first position facilitates the engagement of the contacting surface of the at least one support member to at least one of (a) a longitudinal side of said headrest member and (b) a longitudinal side of said backrest member.
2. The convertible furniture of claim 1 wherein the frame member comprises at least two support members defining at least two contacting surfaces.
3. The convertible furniture of claim 1 wherein said foot member further comprises at least one catch member to releasably engage the cross-bar to maintain the articulating assembly in said second position and to disengage the cross-bar to allow said articulating assembly to be moved to said first position.
4. The convertible furniture of claim 1 wherein said headrest and backrest members are pivotally connected.
5. The convertible furniture of claim 1 wherein said backrest and foot members are pivotally connected.
6. The convertible furniture of claim 1 wherein in said second position, the headrest member extends in angular relation to the backrest member.
7. The convertible sofa of claim 1 further comprising at least one biasing member interconnected between said headrest member and said backrest member.
8. The convertible sofa of claim 1 further comprising wheels attached to the footrest member.
9. The convertible furniture of claim 1 wherein said foot member further comprises at least one catch member to releasably engage said frame member to maintain the articulating assembly in said second position and to disengage the frame member to allow said articulating assembly to be moved to said first position.
10. Convertible furniture comprising:
a base frame comprising;
at least one frame member positioned in general horizontal relation to supporting floor surface wherein the frame member includes a cross-bar positioned in general horizontal relation to the floor surface and interconnected to the frame member;
at least one support member interconnected to said cross-bar, said support member defining a contacting surface; and
an articulating assembly comprising:
a quadrangle headrest member having opposed lateral side members and opposed longitudinal side members;
a quadrangle backrest member having opposed lateral side members and opposed longitudinal side members; and
a quadrangle foot member further having opposed lateral side members, opposed longitudinal side members, and at least one catch member;
the headrest, backrest and foot members being connected to each other such that the articulating assembly is selectively movable between a first position wherein the headrest, backrest and foot members extend in generally co-planer relation to each other, and a second position wherein the headrest and backrest member each extend at a particular angular relation to the foot member, the at least one catch member configured to releasably engage said cross-bar to maintain the articulating assembly in said second position and to disengage the cross-bar to allow said articulating assembly to be moved to said first position; and
the articulating assembly and the base frame being oriented relative to each to each other such that the movement of the of the articulating assembly to the first position facilitates the engagement of the contacting surface of the at least one support member to at least one of (a) a longitudinal side of said headrest member and (b) a longitudinal side of said backrest member.
11. The convertible furniture of claim 10 wherein the frame member comprises at least two support members defining at least two contacting surfaces.
12. The convertible furniture of claim 10 wherein said headrest and backrest members are pivotally connected.
13. The convertible furniture of claim 10 wherein said backrest and foot members are pivotally connected.
14. The convertible furniture of claim 10 wherein in said second position, the headrest member extends in angular relation to the backrest member.
15. The convertible sofa of claim 10 further comprising at least one biasing member interconnected between said headrest member and said backrest member.
16. The convertible sofa of claim 10 further comprising wheels attached to the footrest member.
