KARPEN BED DAVENPORT Dec. 16, 1952 Filed Nov. 9, 1946 Patented Dec. 16, 1952 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to a bed-davenport, and more particularly to a bed-davenport which presents one reclining surface when the apparatus is used as a bed and a seperate reclining surface when it is used as a davenport.

A bed-davenport comprises apparatus which is adapted to be used either as a bed or a davenport, and when arranged for use as a davenport the bed portion is folded inside the structure to an inoperative position where it is out of sight and out of the way, thus distinguishing this type of apparatus from a roll-a-way wherein the bed structure does not fold inside the davenport structure, but may merely comprise a cot adapted to be stored underneath the davenport.

Among the features which are desirable in such a bed-davenport are rst, the apparatus should be easily convertible from a davenport to a bed and vice versa; second, the structure should be as compact as possible; third, the apparatus, especially when set up as a davenport, should present a pleasing appearance and should preferably resemble an ordinary davenport as much as possible; fourth, the apparatus should be of simple and sturdy construction; fth, the apparatus should be comfortable whether it is used as a davenport or as a bed.

Although many bed-davenports have been devised in the past they are all subject to certain disadvantages or shortcomings when compared with the above mentioned desirable features. For example, many of such prior art devices require that the bed structure be folded into three or more parts when the apparatus is converted to a davenport, and that these parts be inverted or folded back upon themselves so that they may be stored within the davenport structure. Such a construction is obviously disadvantageous, for the parts are heavy and cumbersome and do not readily lend themselves to inversion and folding. Furthermore such structures are often highly complex, and the parts easily become jammed or in some other manner get out of order.

Many of such prior art devices are exceeding- 1y bulky when used as a davenport, this bulk being necessary in order to give room in which to store the bed structure, and it has often been attempted to minimize this disadvantage by utilizing the same reclining surface when the apparatus is used as either a bed or a davenport. This has obvious disadvantages, for since the upholstery of the davenport may be expensive it is very often desirable to provide a bed surface other than this upholstery. Furthermore, the contours of the upholstered seat and back member do not readily lend themselves to provide a sleeping surface.

I have devised and am here disclosing and claiming a bed-davenport which eliminates the disadvantages of all known prior art structures, and which includes all of the desired features set forth above. My new bed-davenport includes a two section bed frame and is easily and simply converted from a davenport to a bed and vice versa, since the bed frame merely pulls out from the davenport structure, and is not necessary to invert any portions of the relatively heavy and bulky bed frame in making such conversion. My apparatus includes a novel linking arrangement between the bed frame sections and other portions of the apparatus, which linking arrangement allows the apparatus to operate eiiciently and smoothly and to be very easily converted when desired. When the apparatus is used as a davenport the front section of the two section bed frame rests beneath the upholstered seat, and the back section is arranged at substantially right angles to the front section behind the upholstered back, and when it is desired to use the structure as a bed my novel linking arrangement allows the front section to swing upwardly and forwardly and the back section to swing downwardly and outwardly without striking the supporting frame, until such sections are in alignment with each other to provide the bed surface. Such a construction results in a very compact unit, and my improved linking arrangement allows the parts to swing from davenport to bed position in a minimum of space, and therefore I am able to construct my apparatus to resemble an ordinary davenport. This is facilitated because the bed structure is equally divided beneath the seat and behind the back.

Since I use only a two part bed frame and since neither of the parts require inversion or folding back one upon the other, my linking arrangement is simple and sturdy, and there is no danger of the parts jamming or in some other manner getting out of order. tage of my improved structure is that my improved bed-davenport may include a bed spring of substantial depth, as for example a box spring, and a full size mattress (a felt mattress or'even an inner-spring mattress if desired), thereby presenting a comfortable full double bed size reclining surf-ace which may be, for example 54 inches wide, when the apparatus is used as a bed, and the novel construction mentioned above allows this full size spring and mattress to be car- Y, ried by the bed frame so that they are completely A further advanl3 out of sight and out of the way when the apparatus is set up as a davenport.

These and other features and advantages of this invention will be apparent from the following specification and from the drawings, in which:

Figure 1 is a section through a bed-davenport embodying my inventions, showing the parts in one position; Figure 2 is a section through the beddavenport showni in Figure l, but showing the parts in another position; and Figure 3 is a section through the bed-davenport shown in Figure 1 showing the parts in still another position.

Referring now to the drawings, one particular form or" apparatus embodying my invention is shown in Figure 1 as being arranged as aidavenport. Figure 3 shows the same apparatus ar` ranged as a bed, while Figure 2 shows the apparatus with the parts in an intermediate -position. The apparatus comprises a frame which may be constructed of woodor other suitable material and which comprises a front member it, `a side piece l'l, and' a back yframework including a back member I2, a top member I3 and a back cushion support Ill which is fastened to the top member I3 in such manner that a well or'rec'ess exists therebetween.

The davenport structure is'completed through the upholstered back I5 and the upholstered front IS. Whilethe members I5 and i6 are referred throughout thisspecication and claims as being singular, it wiilbe understood'that suchrespective members may each be made up of two or more upholstered members 'if desired. rlhe back I5 comprises a' supporting member I5dJ and a member Ib which'may be upholstered in any manner desired and which may be designed with internal springs and padding in the conventional manner. In theembodiment illustrated the back is movable and is shown asbeihg mounted on the forward end of the top member I3 by means of the simple hinge II so that the member can be swung upwardly to apo'sition above the supporting frame, althoughany other type of 'mounting maybe used if desired.

r)The upholstered seat l which also include conventional springs Yand padding, is movably connected tothe frontin'ember le of the supporting frame, such connection being here shown asv a pivotal mounting about a moving center. A bracket I8 isk carried by Said seat and extends downwardly (in Figure l) from the lower front corner of said seat to provide a mounting bracket and a step or rest as shown in Figure 1 .l An l.- shaped link member I9 is pivotally connected to such bracket, the other end of this L-shaped link being pivotally connected to one end of another link 20, the other end of which is pivotally connected to the side piece II adjacent the front member Hl. A link 2l has one end pivotally connected to the protruding end of the bracket I8, and its other end is pivotally connected to a link 22, the other end' of this last mentioned link being pivotally connected to the side piece I I behind and below the point where the link 2i) is connected to said side piece. The link members 20 and 2l are pivotally joined intermediate'their ends at 23 where said members cross each other.

This construction results in the seat I6 being pivotally mounted about a movable center, and said seat may be swung upwardly and forwardly of the supporting frame and inverted to the position shown in Figures 2 and 3. When in such position the inverted forward portion ofthe seat is supported by the leg'24 and the rear portion of the seat is moved away from the front member I0 and is supported by the linking arrangement just described. These support members are so constructed that when said member is inverted its upper surface is as high above the floor as is the top of the front supporting frame member I0. It will be understood that the linkage just described at one end of the bed-davenport is duplicated at the other end.

The bed structure of my new bededavenport comprises a two section frame, vone side of the front section consisting of the channel iron 25 -which is adapted to rest beneath the seat when in inoperative position, as when the structure is being used as a davenport, and a back section one side of which comprises the channel iron 26 which 4is adapted to rest in inoperative position at right angles to the front section and behind the upholstered back when the structure is made up as a davenport. Of course similar frame members are used at the other end of the structure,v and there are lalso va plurality of members connecting the side members of the respective frames. A two section bedspring of substantial depth, here shown as a box spring comprising the sections 2'1 and 28, is carried by the two section frame. The spring section 2i is bolted to the front frame section and the spring section 28 is bolted to the back frame section. 'lne sprung sections each nave a width equal to the length of the channel irons 25 and land are of suon a depth that adjacent edges of said spring sections approach each other. If 1t is oesiredtne sections may oe hinged together along these adjoining edges. A mattress 29 may be carried by the two section spring to providea reclining suriace when the apparatus is made'up as a bed. y l

In the past it has been found very diihcult'to design a bed structure which could be brought out from within the davenport structure Without inverting one or more of the bed structure parts or without designing an excessively bulky davenport in order to allow the bed structure to clear the frame. I have devised a simple but novel linking arrangement whereby the parts are linked to each other and to the supporting frame in such manner that the front frame section moves upwardly and forwardly and the back vframe section moves downwardly and forwardly and into alignment with the front frame section to form a bed surface. My improved linking arrangement allows these operations to take place while the frame sections carry the box spring and the mattress, and the bed structure clears the supporting framework, while at the same time the whole apparatus is constructed with little more bulk than is found in a conventional davenport.

Horn shaped bracket members 30 and 32 connect adjacent portions of said frame sections, the bracket 3Q being rigidly secured near the bottom or the pack iraine section niemeer ze by means of the bolts or rivets 3 I, and the similar horn shaped bracket member 32 being rigidly secured near the back of the front frame section member 25 by means of the bolts or rivets 33, these bracket members being pivotally joined together at 34 by means of a bolt or rivet. My apparatus is so constructed that the pivot point 34 is spaced from each of said frame sections a distance substantially equal to the depth of the bed spring so that as the front and back frame sections pivot with respect to each other the bed springs will stay close together, and when the frame sections are in alignment with each other the bedspring sections will adjoin or even touch each other.

At each end of the bed-davenport three linkage systems join the apparatus together so that the frame sections can be moved from the inoperative position shown in Figure l to the operative position shown in Figure 3 without inverting either section. The linking means to be hereinafter described comprise linkage systems each including linking members which are all pivotally connected. In the description of such linkage systems it will be understood that every connection of each link member is pivotal, and in order to shorten the description, such connections will not be again referred to as being pivotal. The rst linkage system comprises a link member 35 connected between a low and rear point on the supporting frame and a point on the back frame section member 26 above the center of said frame section. In the embodiment of my invention illustrated in the drawings this link member is connected by means of a rivet 36 to the bracket 31, said bracket in turn being connected to the side piece I I by means of the bolts 38. The other end of the link member 35 is connected to the back frame section member 26 at a point 39 above the center thereof by means of a bolt or rivet.

A second linkage system is connected between a higher and more forward point on the supporting frame and a lower point on the back section, and comprises a link member 4I] connected to the side piece I I by means of the bracket 4I, the other end of said member being connected to the link member 42 which is connected to the back frame member 26 at a point below the point of connection 39.

A third linkage system is connected between an intermediate point on said supporting frame and a still lower point on the back section, and comprises a link member 43 connected to the side piece II at a point between the brackets 31 and 4I, the other end of said link member being connected by the link member 44 to the back frame section member at a lower point than the point of connection of the link members 35 and 42. The second and third linkage systems are interconnected by means of a link member 45 which is connected between the point of connection of the link members 43 and 44 on the one hand and the link member 40 at a point intermediate its ends on the other hand.

Stop means comprising a block member 46 is secured to the side piece I I by means of the bolts or rivets 4l and operates on the link member 35 to limit the movement of the movable two section frame and to support the back end of such frame where the structure is made up as a bed.

At each end of the bed-davenport a fourth linkage system connects the front frame section from a point near the forward end thereof to the seat I6, said linkage system comprising a link member 48 connected to the front frame section member 25 at a point near the front edge thereof, the other end of said link member being connected to the link member 49 which is in turn connected to the seat at a point near the center of the bottom of said seat.

The apparatus is shown in Figure 1 as being made up as a davenport. If it is desired to convert the apparatus into a bed, the upholstered back I5 is pivoted upon its hinge II and swung upwardly to inoperative position above the supporting frame as shown in Figure 2. The upholstered seat is then swung upwardly and forwardly, said seat pivoting about the movable center to a position as shown in Figure 2, and being supported in such position on the leg 24 and the linkage system earlier described.

The fourth linkage system described above causes the movable frame sections to start their movement toward operative position as the seat is pivoted. This movement is caused because of the links 4B and 49, and when the seat is pivoted the front frame section moves forwardly and upwardly and the back frame section swings forwardly as shown in Figure 2. The front frame section is then pulled forwardly, and the three linkage systems heretofore described cause the two frame sections to move into alignment with each other into the position shown in Figure 3. As can best be seen in Figure 2 the whole bed structure stays very low in the middle in the initial stages of movement, thereby allowing the back frame section to swing down and clear the back cushion support I4, and the linkage arrangement causes proper alignment of the two frame sections. The stop member 46 contacts the link 35 and stops forward movement of the frames and also acts as a support for the rear portion of the back frame. As shown in the drawings the box spring and the mattress are carried by the frame sections `and are automatically moved to the proper position by the movements above described.

When it is desired to recouvert the apparatus into a davenport the operations described. are simply reversed. That is. the front frame section is pushed backwardly, thus causing the back frame section to swing around to a substantially upright position and to clear the back frame support Iii during such movement. When the parts have reached the position shown vin Figure 2 the seat I 6 is pivoted back around its movable center and the apparatus is now made up as a davenport.

While I have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims.
