DAVENHKBE' This invention relates to bed doven 'ior'cs and more particularly to bed dovenports of the back-rest type.

The objects of the invention are to provide a bed davenport in which the back-rest. may be shifted to a position where it will serve as a part of o bed bottom. the shifting being accomplished with a minimum expenditure of offers; to provide means for out .10 moticeily assuring proper positioning oi the beck-rest in either its bed posifion or bowl-o rest position; to provide on article odor the moxinnnn oi comfori, when used as o enport or as a bed, and lo provide on :iri'icle 15 of the class described in which the lmciorcst and the bed bottom section may be made of similar size and shape and oi like parts, whereby a minimum number of ports are is quiz-ed end assembly oi' i'zhe oiiiiie facili- 29 fished, thus substantially reducing the cosh of manufacture.

Other objects are to provide :1 strncltm'e which heat in appearance, coin nreiircl light in Weight, simple a d rugged, and in general to provide an improved structure of the class described.

fisher objects and advantages of the incention will become apparent when the follow ing specification is considered in connection 39 with. the accompanying drawings wherein i have illustrated a selected embodiment of my invention and in wbichzl. is an end elevation showing my bed dnrenpori; in position for use as n davenport.

Fig. 2 is a transverse section showing my bed davenport arranged for use as o bed.

Fig. 3 is a side elevation looking at the right-hand side of F 1, and

Fig. i is a perspective of a detail of construction.

Referring now to the drawings, 1 have in dictated a supporting frame comprising and frames 11. and 12 which are connected and rigidly sin'ported in lheir cooperative position' by means of side ra ls 13 131d 14. The

side-rails l3 and i l may be conveniently connected to the end frames by means of suit able brackets 15 having a nofch in their on per edges adapted to receive a hooded pin sccured to and projeciing from the verlicol Application filed ficptcmber 53, 1928. Serial No. 133,107.

The outer side of the bed bothnn 16 is supperiod by moons of 21 pair of depei'uling; legs 32: 3 and 225 which are secnrml to the respective corners oi" the ilWl bottom frame. The lower ends of fhe lees ore provided With cnsiers or rollers Qel which engage the floor to facilitate movement oi the bed botcom. as will be hereinafter explained. The inner side oi? ihc bed bottom 16 is slidably supported by the sup-- 'IQUilllllg" frame, which frame is provided with n pnir of transverse channel n'lcnibers wh ch so". med lo the side rails 13 and 14. A. pair of roller brackets Q6-26 are secured to the side member 18 of the bed bottom and are provided with suitable rollers 2Z :?7 which enter the respective channel members 25-25 and (.1. e adapted to roll on the lower horizontal flange thereof. It Will be apparent that the bed boil/om 16 may he slid outwzn'diy from its position shown in Fig. 1 to the position as shown in Fig. 2.

A backrest 28, preferably of the some general construciiion as the bed bottom 16. 1' provided end is hingedly or pivotelly connected to the bed bottom by suitable means. In the present instance I prefer to effect connection of the back-resin and bed bottom at their adjncent edges by means of a pair of brackets, one seemed to the backrest and one to the bed botioni and preferably each comprising link members 29 and 30 which are secured to nether by riveting or other suitable means, as indicnted of 31, end which are secured to the he? bottom or backrest indicoted at 32 :2 dd 35 respectively. The links 29 each extend short dishince beyond the eonnceiion ill with the shortlinlr. SO and more pivoteliy cone nected at their ends as indicated at 34. The pivotal connection 34 preferably includes a roller 35 which projects outwardly from the brackets and which is seated in a track 36 secured to the corresponding end frame. The track 36 is preferably of channel construction so as to limit movement of the roller 35 in both an upward and adownward direction whereby upward movement of the inner end of the bed bottom is prevented and part of the load which normally would been the supporting rollers 27 is taken therefrom and carried by the roller 35. By this means I may safely use structure of lighter weight than otherwise would be proper.

'Phe back-rest 28 is thus partly supported by its connection with the bed bottom and by engagement of the roller 35 in the track 36. I further support the back-rest by means of a bell crank lever 37 which is pivotally mounted on a portion of the supporting frame by means of a suitable bracket 38 as clearly shown in Fig. 4. The long or upwardly extending leg of the bell crank is pivotally connected at its upper end as indicated at 39 to the back-rest. The lower arm or inwardly extending arm is connected by means of a suitable tension spring 40 with a portion of the supporting frame as by means of a depending bracket 41 as most clearly shown in Figs. 1 and 2. It will be understood that I refer to connect the back-rest and the bed bottom at their opposite ends in the manner described above in connection with one end and also that I prefer to provide'the above deslcribed bell crank arrangement at both enc s.

In changing the bed davenport from the davenport position shown in Fig. l to the bed position shown in Fig. 2, the operation is as fnilows :The operator pulls the bed' bottom 16 outwardly which slides or rolls on the floor and on the channel track members 25-25 as above explained. Because of the pivotal connection at 34 between the bed bottom and back-rest, the back-rest is caused to move forwardly with the bed bottom and swings about the pivotal mounting of the bell crank 37 on the supporting frame or bracket 38. As the back-rest 28 swings as above described, it swings about the hinged or pivotal connection.34 with the bed bottom and also turns on its pivotal connection 39 with the end of the bell crank lever 37. It will be apparent to those skilled in the art that sufficient forward or outward movement of the bed bottom section will cause the back-rest to assume a position substantially co-planar with the bed bottom as shown in Fig. 2. In order to more firmly support the back-rest in this co-planar position I preferably provide the lower bracket 26 which is secured to the bed bottom with an outwardly extending shoulder or seat 42 on which the forward end of the backrest is adapted to be seated. The rear end of the back-rest adapted to be seated on a small supporting bracket'43 as best shown in Figs. 2 and 3, the bracket 43 being secured in place on the upper flange of the channel member 25.

The spring 40 which is connected between a stationary part of the supporting frame and the lower end of the bell crank lever 37 is effective to prevent sudden dropping of the back-rest into its bed position because, as the bell crank 37 swings on its pivotal mounting on the frame, the spring is stretched and acts as a counterbalance. The spring is preferably of such strength that it will not of itself cause the back-rest to return to its davenport position but will prevent sudden placement or slamming into bed position, whereby durability of the article is greatly increased.

To return the structure to davenport position, the operator merely lifts on the outer edge of the back-rest so as to effect a reversal of the above described operation of converting the davenport to a bed. In this operation the spring 40 will obviously be effective to offer material assistance to the 0 erator since the spring normally tends to swing the bell crank in the direction in which it must travel in bringing the back-rest from the bed position to the davenport position. Inward movement of the bed bottom is limited by engagement of the legs 22 and 23 with the side rail 13, suitable provision being made to permit the legs 22 and 23 to move inwardly so that their inner edges will engage the vertical flange of the side rail. The legs 22 and 23 and the outer edge of the bed section do not, therefore, project outwardly an objectionable amount. Swinging of the back-rest 28 with the bell crank 37 about the pivotal connection of the bell crank with the supporting frame and turning movement of the backrest about its pivotal connection with the upper end of the bell crank. is limited because of its connection with the bed bottom which, as above explained, is limited in inward movement.

I prefer to provide the pivotal conection 34 between the bed bottom and the back-rest at a point spaced above the bed bottom a distance substantially the same as the thickness of a mattress or cushion which it is desired to use for increasing the comfort qualities of the bed davenport. It will be readily understood that by bringing the pivotal connection up to the top of the mattress or cushion that interference with the movement of the back-rest from one position to another, by the mattress or other bedding, is avoided. By making the back-rest and bed bottom of substantially the same size and construction, I eliminate the necessity of a large number of parts and thereby facilitate manufacture and assembly, whereby the cost of construction is lowered.

I am aware that various changes in size,

proportion of parts, and construction, as well as arrangement, may be readily made Without departing from the essence of the invention, and I, therefore, reserve the right to make such changes as fairly fall Within the l scope of the following claims, which should be construed as broadly as possible consistentv with the state of the art.

I claim as my invention: 1. In abed davenport, the combination of a supporting frame, a seat section mounted on said frame so as to be adjustable from normal seat position to extended bed position, a back rest section normally extending up- I I wardly from said seat section and hinged thereto, whereby adjustment of said seat section from its normal position to its bed position incidentally eflects adjustment of said back rest to bed position, an arm pivotally connecting a point at the rear of said frame, with a point intermediate of the height of said back rest, said arm serving to control the adjustment of said back rest, and spring means connected between said arm and said frame, tending to swing said arm rearwardly on said frame and effective for such purpose through substantially the entire arc of movement of said arm, for counterbalancing the weight of said back rest during adjustment thereof.

2. In a bed davenport, the combination of a supporting frame, a seat section mounted on said frame so as to be adjustable from normal seat position to extended bed position, a back rest section normally extending upwardly from said seat section and hinged thereto, whereby adjustment of said seat section from its normal position to its bed position incidentally effects adjustment of said back rest to bed position, a bell crank pivotally mounted on a rear portion of said frame and below said back rest, said bell crank having a long arm extending upwardly and pivotally connected at its upper end to a point intermediate of the height of said back rest, and a short arm extending forwardly beneath said seat section, and a tension spring directly connected between the outer end of said short arm and a front part of said frame, said spring tending to swing said long arm rearwardly and being effective for such purpose through substantially the en tire arc of movement of said arm, for counterbalancing the Weight of said back rest during adjustment thereof.
