Abstract

A chair convertible into a bed, comprising a stationary frame having a seat member positioned therein and displaceable therefrom to extend in a forward direction and a support member positioned in the frame below the seat member and displaceable thereby to extend in a forward direction. A back-rest is hinged to the seat member and is adapted to move therewith from an upright position in the frame into a substantially horizontal position beyond the frame in a forward direction, coming to rest coplanar between the seat member and a reclining surface which becomes exposed when the back-rest and seat member are extended.

Claims

1. A chair convertible into a bed, comprising:

a stationary frame having an upright portion provided with a backrest stop;

a seat member positioned on said frame and displaceable relative thereto to extend in a forward direction;

a support member positioned in said frame below said seat member for the support thereof and displaceable thereby to extend in said forward direction, said seat member being connected to said support member;

a body defining a bed-forming surface positioned in said frame below said seat member and above said support member when said members do not extend in said forward direction;

a backrest hinged to said seat member and leaning on said stop in an upright position of the backrest, said backrest being displaceable by said seat member to assume a horizontal position between said body and said seat member on a level therewith, said backrest being pivotally connected to said support member in all positions; and

means in said frame for guiding said members for the displacement thereof;

2. A chair as defined in claim 1, further comprising a protective cover positioned within said frame in a stored condition and extendible therefrom in said forward direction to cover said surface, said backrest and said seat member in the extended position of the latter.

3. A chair as defined in claim 1, further comprising:

a first link pivotally connected to said backrest and said support member for the movable support of said backrest;

a second link pivotally connected to said seat member and said support member for the movable support of said seat member; and

said backrest is hinged to said seat member by a hinge provided with releasable locking means for maintaining the angle between said backrest and said seat member during the displacement thereof.

4. A chair as defined in claim 1 wherein the guide means comprises:

runners formed on said frame and extending in said forward direction;

first rollers provided on said support member and engaging said runners;

second rollers provided on said support member and riding on the floor; and

means for stopping said support member at a predetermined extension thereof.

5. A chair as defined in claim 3, further comprising:

a leg rigid with said seat member for resting on said support member in an unextended position thereof and for resting on the floor in an extended position of said seat member; and

a storage space provided in said support member and accessible in an extended position thereof by pivoting said seat member into an upright position.
