The present invention relates to improvements inchair beds, and i a division, of my co-pendingapplication, Serial Number 335,593, filed May l6, 1940, which latter application was 'a contin ution in-part of my application, Serial Number 309,855, filed December 18,1939.. f X

' The general fobje'ctof the invention is to provide improvements in a chair bed constructed in such a manner thatit may be Conveniently op-i erated by. an occupant between chair and bed positions by the mere shifting of weight of the bodyof the occupant.

More particularly it is. ent inventiom'to arrange the chair bed in such amannerthat it may be changed from a chair a into a bed without causing the rear edge to project rearwardly very far beyond its original rear plane. This feature allows a chair of the character described to be placed with its top rear edge relatively close to the wall of a room and to be changed into a bed without the necessity of moving the chair bed as a whole.

It is further proposed in the present invention to provide a chairbed comprising a main supporting frame and a movable frame structure ineluding rigid back and seat sections hinged together and means for supporting the frame structure on the main frame with freedom of floating movement between chair and bed positions.

Another object of my invention is to provide a peculiar link mechanism as a support for a movable frame structure, the said mechanism allowing the back section to rock on an intermediate support when the upper end of the back ispressed downward and, at the same time, exerting a forward pull on the back section, whereby the entire movable frame is pulled forward toward bed position.

Afurther object of the invention is to provide an improved supporting means for the seat causmg the latter to advance and ris to a position of alinement with the back section as the latter .istilted and lowered into horizontal position.

bed. r

While I have shown only the preferred forms of my invention, I wishto have it [understood that various changes, and modifications may. be.

made within the scope of the claims hereto attached, without departing from the spirit of the invention.

Referring to the drawingin detail, Figure 1 shows a main frame I comprising side members 2 adapted to serve as arm rests for an occupant of the chair, and end members3 and 4, one in the rear of the frameandthe other in the front The rear member is shown as being considerably higher than the front member, and the frame is preferably supported onshort legs 5.

The movableframe structure 6 comprises a back frame I and a seat frame 8, the two frames being hinged together, as at 9, for swinging movement between angular and alined positions.

Suitable upholstery It] covers the entire movable tially the same as that disclosed in my co-pending application, Serial Number 309,855, above referred to.

For upporting the movable frame structure, I provide two

links

35 and 36. The link 35 is pivoted to the bottom of the main frame, near the rear wall, as at 31, and to an intermediate portion of the back, by the pivot 38.

The link 36 is pivoted to the frame at its upper end, as at 39, and has its lower end pivoted to a bracket 40 projecting downwardly from the rear edge of the seat, as at 4|. Shoes 42 are provided for raising the seat as it is moved forward.

In operation, when the upper end of the back is pressed downward, the back rocks on the pivot 38, and the hinge 9 moves forward. This forward movement of the hinge is accompanied by a similar forward movement of the bracket 40 and its pivot 4|. Since the latter pivot has to follow the path of an are about the center 39,

with the link 36 serving a radius, it will move Inasmuch as the hinge 9 has to follow the path of the pin 4|, it is apparent that it will imme NroFFicE If, therefore, the back of the chair is located relatively close to the wall of the room, the converting movement may be effected without first moving the entire chair bed aWay from the wall.

During the converting movement, the shoe on the seat rides on the front wall 4 of the chair bed, and raises the seat to a position of a'linement with the back when the latter drops into horizontal position, as shown in Figure 2.

In the latter position, the back and the seat are supported on the rear and

front members

3 and 4 of the main frame, and the links cooperate in holding the movable frame unit in horizontal position.

It will be noted that the pivot 39 is almost vertically above the pivot 31, and that the free end of the link 36 is forward of the free end of the link 35 in both positions.

To reverse the movement, it is only necessary to lift the projecting end of the back section, which will automatically cause the different parts to resume the position of'Figure 1.

The form shown in Figure 3 differs from the first form principally in the shape of the main rear ends thereof, standards [4 rising from the front ends thereof, and connecting members l5 and I6 forming front and rear supports for the mattress units in horizontal position. The

bracket 40 is directly secured to one of the hinge v leaves by means of bolts 43 passing through the seat frame. I

It should be understood that throughout the specification, where the term link has been used in the singular, this has been done for the sake of simplicity, and that, inreality, the same link mechanism is used on both sides of the chair bed.

I claim:

1. In a chair bed, a main frame, a back and a seat having a hinge connecting the same, two links, each having one end pivoted to the main frame near the rear thereof, one near the bottom and the other near the top and substantially vertically above the former, a pivotal connection between the other end of the first link and an intermediate portion of the back, a bracket projectingdownwardly from the seat, and a pivotal 2. In a chair bed, a main frame, a back and a seatis'ection hingedly connected together to form a foldabl "unit, two links, each having oneend pivoted to the main frame near the rear thereof, one near the bottom and the other near'the top and substantially vertically above the former, a pivotal connection between the other end of the first link and the intermediate portion of the back section of the unit and a pivotal connection between the second end of the second'link and the unit adjacent the hinge thereof, the said unit beingo-perable by means of the said links to travel bodily forward cnthe main frame with the tilting ofthe said back.
