COMBINATION ADJUSTABLE BACK AND BED CHAIR V I Irvin C. Poskin, Los Angeles, Calif. Application March 30, 1948, Serial No. 18,035

1' Claim. (Cl. 155162) The present invention relates tochairs and particularly to a combination adjustable back and bed chair.

On account of the present housing situation and the crowded conditions in homes, apartment houses and the like, it is not infrequent that make-shift accommodations must be providedfor guests who are unable to find hotel accommodations. Under certain circumstances due to the numbers in families, the livingroom has to be turned into a guest room. To provide means whereby the guest can recline instead of sit 'is one of the objects of this invention in providing this combination bed chair.

Another object of the invention is to provide in a bed chair of this type hidden means whereby the chair can be operated without disclosing that it is other than a comfortable upholstered chair.

Another object is to provide in combination with an ottoman, an adjustable chair which is more convenient for operation from an upright to a horizontal position to form acouch for an adult.

Fig. 6 is a sectional detail, the plane of section being indicated by arcuate line 6-6 on Fig. 5.

Fig. 7 is a perspective view showing separately the upstanding release lever. V I

Fig. 8 is a perspective View of the complete chair adjusted to form part of a bed, a conventional ottoman being shown juxtaposed to the left end of the chair to lengthen the chair sufliciently to form a bed for an adult.

side pieces I5, and a lower crosspiece structure- IB having forwardly offset end portions I! with which cooperate the pivot bolts [8 that are con- A further and more specific object is to provide, and mount on the back of the chair frame, a bracket plate which forms a superior bearing and supporting means for parts of the means for releasably locking the chair back at the desired inclination and elevation.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawings, which illustrate a preferred, reduced to practice, embodiment of the invention,

Fig. 1 is a rear elevation of the device adjusted to form a chair only, the lower part of the structure and a side portion thereof being broken away in order to contract the view. The rear fabric covering is omitted to disclose the release mechamsm.

Fig. 2 is a horizontal section taken on the plane indicated by line 2-2 on Fig. 1. The scale is larger than in Fig. 1 and one of the operative positions is shown in dotted lines.

Fig. 3 is approximately a reproduction of a part of the left hand portion of Fig. 2 on a larger scale, the plane of section passing diametrically through the screw-containing cylinder. One of the operative positions is shown in broken lines.

Fig. 4 is a vertical section on line 44 of Fig. 1, a rearward adjustment being indicated in broken lines, the upholstering being shown in the upper portion of the view.

Fig. 5 is a fragmental section detail on line 5-5 of Fig. 2, the scale being enlarged.

nected to the chair arms 12.

Adjacent to each lower corner the chair back structure [3 has a rearward extension 20 consisting of a block bolted or otherwise secured in place. Said blocks are each horizontally bored through to provide for having fitted within them the cylindrical casings 2| of the locking bolts 22. Said bolts are axially screwed onto stems 23 each of which has a diametrically enlarged end,

portion 24 terminating in a rounded head 25. The end of the lock casing 2| adjacent to the part 24 has an inturned fiange 26 which loosely receives the stem 23. Against said flange abuts a coil spring 21 which tends to move each bolt to locked position. Each bolt 22 cooperates with a series of locking recesses 28, 28a in an arcuate, ratchet-like strip 29 attached to the adjacent part of the arm rest I2 at that side of the chair structure.

Simultaneous retraction of the twin locking bolts 22 is effected by means of a pair of wire traction rods 3|, 31a having outer ends secured to the heads 25 and inner ends secured to the opposite ends of a common operating lever 32 which, at its midlength is secured to an operating shaft 33. Said operating shaft 33 (see Fig. '7) extends through a lower bearing strip 34 and an upper bearing strip 35 carried by the chair back and above the latter strip carries a rightangularly directed handle 36. Said handle closely underlies and is concealed by the back cover member 37 of the upholstering 38, so that the user of the chair, while seated thereon, can release the locking bolts by reaching his right hand over the back of the chair and applying pressure to said handle.

The aforesaid lower bearing strip 34 has a bracket plate 39 secured pendantly to its back side, said plate having in its lower portion a supporting notch 40 with a horizontal lower side portion which supports the aforesaid lever 32 5 during its swinging movements, thus preventing the lever and its operating means from dropping down from their proper operative position.

As shown most clearly in Figs. 5- and 6 the upper locking recess 28a difiers from the other recesses of said strip in that at its upper side it has a horizontal or rightangularly extending stop shoulder 41 whereas the corresponding shoulders or bevels 42 of the other recesses slope ingsuchl a manner as to allow the locking bolt to glideup wardly over them. 7

When it is desired to place the chair 'baciam a more inclined position than that shown imFigl- 1, the person sitting in the chair reaches his right hand over his shoulder and presses for 20 wardly upon the handle 36 underlying the fabric. This movement of the handle andf-lever H -retracts the-locking :bolts 22' from the locking recesses wl'iich they engage? Thereupon the pressure of the individuals back againstthechair baok cause's the latter to swing downwardly a selecteddistance; whereupon the pressure of thehandis removed from saidhandle 35;-permitting the locking bolts to be urged out-wardly under the pressure of their springs.

In this manner, if permittedto' droptoa horizontal posit/long the back of the chair is placed" in a position wherein it serves to convert 1 the chair into a bed for-repose-inarecumbent-post tion, especially when associated with-an"ottoman 44; as shown in FigrS: g

Whenit is-dsired to v elevate theback of thechairfrom a horizontal or from a more orless inclined position, allthatit is--necessary-to" do' is to lift up on the-topporti'on of-the'backpf the chair, thus causing the-locking-bolts 22-'to-" glide upwardlypver the "inclined faces"4-2 f the ratchet strip'until-they reach the stop shoulder- 4| of the-uppermost pair of-re'oesses; whereb y*thechairsback is h'eld inthe most steeply inclined position.

It willb'e seenfrom' Figs: land 2--that--the'o'1'1-' erating handle 394s plaeedto theright -of the center of the-chair to make said-handle more a'ccessible for manual operation."

I claim:

In a chair structure of the kind described, a chair frame, a chair back having its lower end portion pivoted to said chair frame so that said chair back is swingable between an upstanding and a substantially horizontal position, releasable locking means for said chair back, said locking means including locking bolts and bolt operating IYOdSg-flfld springs all-mounted upon the normally lower portion ofsaidzchair back and a ratchet carried by each side portion of the chair frame to cooperate with said bolts, said ratchets havingw teeth upwardly over which said bolts may glide? against the opposition of said springs, a L
