Abstract
Abstract A piece of furniture adapted to be transformed in a bed comprising a frame having sides, an upper surface and a facing surface. The facing surface comprises a first lower panel fixed to the sides and a second upper panel connected to the lower panel by a hinge. A third panel is connected to the upper panel by means of a hinge and may be pivoted downwardly so as to be used as a table. The upper panel may also be pivoted downwardly around its hinge and be supported by the said first and third panels to constitute the base of a bed. Springs are foreseen to facilitate the lifting of the upper panel in its raised position.

Claim 1
Independent Claim
332 words
A piece of furniture adapted to be transformed into a bed comprising: a. a frame comprising rectangular side panels, an upper surface panel extending from one side to the other side and pivoted about its rear edge, and a facing part having a first lower panel extending across the lower part of the frame and fixed to each of said sides, and a second upper panel extending substantially over the full front surface of the frame and extending behind the said first lower panel, a retaining plate secured perpendicularly to the edge of said upper panel located behind the said first lower panel for supporting a mattress disposed on said upper panel, the said upper panel being connected to the upper edge of said first lower panel by a first hinge so as to permit a movement of the second upper panel from a vertical to a horizontal position; b. a rigid L-shaped member comprising a third and fourth panel extending across the upper portion of the second panel and connected by a second hinge along its apex to said second panel so that the third panel is adapted to cover the top surface of the second panel when the fourth panel projects forwardly of the second panel, the said member being adapted to tilt downwardly about the second hinge so that the said third panel projects forwardly of said second panel, whereby the first panel and the third panel form a base for the second panel when the latter is pivoted downwardly about the first hinge, and the upper surface panel has a downward lip along its forward edge adapted to hold the said second panel in its raised position; c. stretchable elastic means connected between the lower edge of the second panel and a location adjacent the lower intersections of the side panels and the said lower panel, wherein the tension of the said elastic means increases uniformly from the vertical to the horizontal position of the second upper panel.

A piece of furniture adapted to be transformed into a bed comprising: a. a frame comprising rectangular side panels, an upper surface panel extending from one side to the other side and pivoted about its rear edge, and a facing part having a first lower panel extending across the lower part of the frame and fixed to each of said sides, and a second upper panel extending substantially over the full front surface of the frame and extending behind the said first lower panel, a retaining plate secured perpendicularly to the edge of said upper panel located behind the said first lower panel for supporting a mattress disposed on said upper panel, the said upper panel being connected to the upper edge of said first lower panel by a first hinge so as to permit a movement of the second upper panel from a vertical to a horizontal position; b. a rigid L-shaped member comprising a third and fourth panel extending across the upper portion of the second panel and connected by a second hinge along its apex to said second panel so that the third panel is adapted to cover the top surface of the second panel when the fourth panel projects forwardly of the second panel, the said member being adapted to tilt downwardly about the second hinge so that the said third panel projects forwardly of said second panel, whereby the first panel and the third panel form a base for the second panel when the latter is pivoted downwardly about the first hinge, and the upper surface panel has a downward lip along its forward edge adapted to hold the said second panel in its raised position; c. stretchable elastic means connected between the lower edge of the second panel and a location adjacent the lower intersections of the side panels and the said lower panel, wherein the tension of the said elastic means increases uniformly from the vertical to the horizontal position of the second upper panel.
Claim 3
Dependent Claim
39 words
A piece of furniture as recited in claim 1, in which the upper panel is connected to the lower panel at a certain distance from its lower edge which is slightly smaller than the height of the lower panel.
Claim 4
Dependent Claim
46 words
A piece of furniture as recited in claim 1, comprising a rear panel, inner shelves adapted to receive covers, pillows and other small articles, the said shelves being hidden by the bed in its raised position and fixed to the saId side and the rear panels.
Claim 5
Dependent Claim
50 words
A piece of furniture as recited in claim 3, in which at least one of the side panels is provided with at least one door extending adjacent at least one of the shelves so as to provide access to the said one shelf when the pieces of furniture is closed.
Claim 6
Dependent Claim
80 words
A piece of furniture as recited in claim 4, in which one of the shelves comprises a sliding tray adapted to slide outside one of the side panels through said door, the said tray being solidly mounted in a sliding manner to the said shelf so as to maintain a parallel direction to the said shelf when the tray is pulled outside the furniture, the said tray being adapted to store material accessible when the piece of furniture is closed.
Claim 7
Dependent Claim
77 words
A piece of furniture as recited in claim 1, in which the said elastic means comprises two coil springs, each spring extending between the central portion of the lower edge of the second panel and a part adjacent the lower corner of the intersection of the side panels and said lower panel, whereby the coil springs extend below the lower edge of the second panel in an unstretched condition when the latter is in its raised position.
