16 Claims.

This invention relates to improvements in articles of furniture of the type which have come to be known as davenport beds, that is to say a structure having movable mattress supporting frames which may be relatively folded or extended to provide for either davenport or bed phases of use.

The objects are to provide for maximum ease and facility in the conversion of the article from either phase to the other; to promote a maximum degree of comfort in the use of the article in either phase; to provide a combination of mechanical features which includes the movable mattress supporting frames and is characterized by extreme simplicity and manufacturing economy; and to provide for the permanent association with the movable supporting frames of mattress sections in an arrangement whereby in the davenport phase they are respectively used for the direct support of seat cushions and of an upholstered back element and in the bed phase are in adjoining coplanar relation to provide a mattress of substantially the same width as the mattress of a standard double bed.

The invention, generally stated, consists in sundry novel features of construction, relation and operation pertaining to the mattress supporting frames and means for their support in either phase of use and their guidance during the conversion from either phase to the other. These features will be set forth in detail as the description proceeds.

The supporting element of the structure includes a back frame I of generally rectangular outline and end walls 2. The frame I carries a transversely extending top rail 3 and each end wall 2 carries an end rail 4 and a front rail 5. The end walls 2 are connected and mutually braced by the frame I and also by a transversely extending member 5. The vertical end bars of the frame I provide a pair of rear supporting legs I and the front rails 5 provide a pair of front supporting legs 8. The structure includes an upholstered back element 9 which in respect to its frame, spring and upholstery features may be of any suitable standard or known construction and, therefore, requires no illustration in detail.

The outer faces of all parts of the stationary supporting element, 1. e., the faces which would otherwise be exposed to view, are, as shown in Figure 4, for the purpose of attractive appearance, preferably covered with finishing material of a kind and color which will match the seat cushions and the upholstered back element 9.

suitable character.

The element 9 is provided with end wings in which are arranged above the rails 4 as best shown in Figures 4 and 5 and normally rest against supporting blocks ll (Figures 2 and 12) arranged between the rails 3 and 4 and secured to the vertical end bars of the frame i. The element 9 is connected to the rail 3 by suitable hinges 52 which are attached to the wings iii. Thereby the element 9 may have a normal low cred position in which its wings I53 rest against and receive support from the blocks I l or a raised position as shown by broken lines in Figure 2, the back element being moved manually to its raised position prior to the conversion of the article from either phase of use to the other and thereafter, in either phase of use of the article, being returned manually to its normal position. The blocks I i are co-planar with the side walls 2 and may be considered as functional parts or extensions of the side walls. Their front faces i is against which the wings it normally rest are forwardly and downwardly inclined in conformity to the determined angle at which the back element e is supported. Means is provided for stably holding the back element in its raised position. Such means may be provided at either or both ends of the element and may be of any As shown it consists of links !3 and I4, pivotally connected at their lower ends as at E5, the link !3 being pivotally connected at its upper end as at [6 to the block ll adjacent its inner face and the link [4 being pivotally connected at its upper end as at H to the Wing it adjacent its inner face. The pivotal connection i5 between the links [3 and [4 may be of any suitable and well known construction which will cause the overlying terminal portions of the link to bear with such degree of frictional pressure against one another as will insure the stable retention of the back element in either of its positions. Such pivotal connections usually include springe and frictional washer features and are so well known that the illustration of their details is not required.

According to the invention the structure includes two rectangular inner and outer mattress supporting frames I3 and H3. The inner frame 18 includes side bars 253 and end bars 2| and the outer frame as includes side bars 22 and end bars 23, the several frame bars being conveniently and preferably of angle iron cross section. The side bars are at right angles to the walls 2 and the end bars are parallel to them. Where, as shown, the mattress is to be substantially of double bed width the frame I8 is preferably somewhat narrower than the frame IS in order that it may conform to the standard height and eleva tion of the back element 5 in the davenport phase of use, as will be later described in detail. Each of the frames It and 59 carries a mattress supporting fabric 24 which may be of any suitable known construction.

As shown and preferred the mattress includes sections 25 and 25 which are respectively associated with and supported by the frames 18 and I9 and may be of any suitable construction, preferably that which includes cushioning springs (unnecessary to illustrate). The outer vertical f ace of the mattress section 26 which would otherwise be exposed to view is preferably covered with a strip of finishing material which matches the finishing material used for the rest of the structure. As extended in co-planar relation in the bed. phase (Figure 2) the sections 25 and 23 adjoin and provide a mattress which, as assumed in the drawings, may be of substantially the same width as the mattress of a standard double bed. In the conversion of the structure from either phase of use to the other the mattress section 26 is immovable relatively to its supporting frame it. For this purpose the section 25 is suitably attached to the frame is. This attachment is preferably and conveniently made by means of a suitable number, e. g. of tie tapes 2? (Figures 14 and 15) which are determinately spaced from one another. Each tie tape is stitched at one end to the inner vertical face of the section 2% and its free end is passed through an opening 28 in the horizontal flange of the inner ide bar 222 of the frame 19. The tie tape is looped about the vertical flange of the inner side bar 22 and its free end is secured to the body of the tie tape by a suitable fastener 2, e. a standard ball and socket fastener, one member of which is carried by the tape at its free end and the other member of which is carried by the body of the tape adjacent its point of attachment to the mattress Whenever, for any reason, it may be desired to remove the mattress section as from its supporting frame 39 the elements of the fasteners 29 are disengaged, whereupon the section 26 may be freely lifted from the frame is. Whereas the mattress section 25 is immovable relative to its supporting frame 19 the mattress section 25, during the conversion of the structure from either phase of use to the other, is preferably slidable upon its supporting frame it, its sliding move ment being in a fore and aft direction, i. e., in the direction of the end bars iii of the frame H8.

The mattress sections 25 and 26 are preferably in connected relation whereby during the conversion from either phase to the other they may have relative swinging movements. For this purpose the connection between these sections is in the nature of a hinge, so to speak, and may conveniently be of the construction shown in Figures 13 and 14. Thus the connection may consist of a flexible strip 33 which is bent upon itself along its center line as at 3! to provide leaves 32 which are located between the adjacent faces of the mattress sections and in each instance are attached by stitching to the adjacent mattress section, the strip 39 being coextensive in length with the mattress sections. The bow portion 3| of the bent and stitched strip 35 serves as a hinge axis whereby the sections, remaining in connected relation, may move angularly with respect to one another during the conversion of the structure from either phase of use to the other.

In the davenport phase the inner portion of the outer mattress section 26 extends under the inner side face of the inner mattress section 25 and provides bottom support for the inner mattress section.

The mattress supporting frames i3 and is are hingedly connected, the hinge connections 33 being provided between the adjacent side bars 2i! and 22 and conveniently comprising lugs arranged in pairs and projecting from the vertical flanges of the bars and hinge pins fitted in the lugs. By virtue of the inge connections 33 the frame i9 is utilized in both phases to provide support for the frame iii.

The frames 13 and It as connected by the hinges 33 are employed in combination with means for their support and guidance which is eperatively connected to the supporting element and to the frames and is operative at all times within the confines of the supporting element.

This means dictates the novel and advantageous relationship (to be presently described) of the hingedly connected frames l8 and I9 in both phases and their novel and advantageous relative movements during conversion from either phase to the other. The embodiment of the means for the support and guidance of the frames which is shown and preferred consists of stationary guides of channel cross section for each frame which have novel forms and arrangement and rollers carried by each frame which track in the channels of the companion guides.

The guides 34 for the frame 18 are attached to the side walls 2 (including the blocks I) and are positioned adjacent the back frame I. These guides are similarly formed and arranged in confronting relation and have straight components 35 which at their lower ends merge into forwardly and downwardly extending curved components 3%. ends adjoin the back frame I and from their upper ends are inclined at a suitable angle to the perpendicular in a forward and downward direction. The end bars 22 of the frame I8 carry rollers 31 which track in the guide rails 34 and are located adjacent the outer ends of the bars 2|. Thereby in the davenport phase they are adjacent the then upper side of the frame I8 and in the bed phase are adjacent the then rear side of the frame 8. The channels of the guides 34 are closed at their lower ends by blocks 38 (Figure 9) which provide stops for engagement by the rollers 31, thereby positively to limit the extension of the sections in the conversion to the bed phase.

The guides 39 for the frame it are attached to the side walls 2 and are similarly formed and arranged in confronting relation, being straight and extending at a slight degree of angularity in a rearward and downward direction from points adjacent the front rails 5 to points suitably beyond the forwardly located lower ends of the guides 35. The lower ends of the guides 34 are immediately above, and in adjoining relation to, the guides 39. The front ends of the guides 39 are located in a common horizontal plane with the lower ends of the guides 34 as indicated by the broken line X in Figure 1. The end bars 23 of the frame 19 carry rollers 40 located at their rear or inner ends and which track in the guide rails 39, thereby at all times providing support for the frame It at its rear or inner side. Support for the frame [9 at its front or outer side is provided by depending legs 4| which carry floor engaging casters 42 and are preferably of angle iron cross section and butt welded to the vertical flanges of the frame bars at the front corners of the frame. The legs may be reinforced by gusset plates 43.

In the davenport phase (Figure l) the inner frame l8 extends upwardly and preferably rearwardly at a suitable angle from the outer frame it and its then upper side has lateral support by means of the rollers 31 from the upper ends of the guides 3 The then lower side of the inner frame l8 has direct support from the inner side of the outer frame It by means of the hinge connections 33. The outer frame !9 is confined wholly between the side walls 2, its rear or inner side being supported by means of the rollers 40 from the inner end portions of the guides 39 and its front or outer side being supported by the legs ill. The mattress section 25 is arranged immediately behind the back element 9, its upper portion being confined in the recess provided by the The straight components 35 at their upper top of the back element and the wings l0 and its lower portion being confined between the side walls 2. Thereby the mattress section 25 is wholly concealed from view and is supported by the frame iii in an inclined plane parallel to the plane of the frame. The mattress section 25 provides support for the body portion of the back element, 1. e. the portion which extends between the wings 50. It will be noted that the back element 9 in its lowered position has a forward and downward inclination from top to bottom which conforms to the inclination of the mattress section 25 and which has a degree of angularity that is conducive to comfort. The frame it occupies a plane which is common to the plane of the guides 39. Thereby the frame It has a rearward and slightly downward inclination and the mattress section 26 has a similar rearward and downward inclination. The low-er side of the back element 9 is immediately above the mattress sec tion 26 and the lower portion of the back element 9 is located in front of the lower portion of the mattress section 25 and behind the seat cushions 4d which the mattress section supports. The rearward and downward inclination of the frame is in the davenport phase which results in a similar inclination of the seat cushions at a suitable angle to the inclined back element 9 promotes comfort in the use of the article as a settee or divan.

In the bed phase (Figure 2) the inner or rear side of the outer frame is is supported by the rollers is from the front end portions of the guides 39 and the outer or front side of the frame i9 is supported by the legs ii from the floor. As thus supported the outer frame is has a truly horizontal position which results in the horizontal positioning of the mattress section 25. The inner frame i8 is supported at its then rear side by the rollers 3? from the lower end portions of the guides 34 (Figures 2 and 9) and at its front or inner side is directly supported from the frame !9 by means of the hinge connections 33. Thereby the frame it occupies a truly horizontal plane which is coincident with the plane X (Figure 1) with the resultant positioning of the mattress section 25 in a plane truly horizontal and which may be considered as an extension of the plane of the mattress section 26. The mattress provided by the sections 25 and 25 is of ample width and affords a flat and substantially uninterrupted supporting surface upon which the bedclothes may be arranged.

When the article is to be converted from the davenport phase to the bed phase the seat cushions M are removed and the back element 9 is raised to a suitable extent about its hinges 12 as shown in broken lines in Figure 2. In the pre ferred embodiment herein illustrated the initial phase of the extension of the frames 58 and h is effected by gravity, thereby facilitating the conversion and reducing the physical effort. As extending upwardly and rearwardly and thereby because of the favorable angularity of its position the frame it under its own weight, and aided by the vertical component of the weight of the mattress section 25, has an initial movement which is transmitted to the frame i9 and the mattress section 26 which it supports. This movement of the frame it is of compound character, its rear sid having a component of downward sliding movement in the direction of the straight components 35 of the rails 3s and a component of forward pivotal movement about the axes of the rollers 3?. The pivotal movement is prescribed by the connection of the frame l8 through the hinges 33 to the frame i9 and results from the fact that the inner or then lower side of the frame it follows the inner side of the frame l3 as it travels outward by means of the rollers ii] along the guide rails 38.

The initial movement of the frames l8 and is as effected by gravity may be ultimately arrested by suitable counterpoise means which may conveniently consist of helical springs 45 arranged adjacent the inner faces of the side walls 2 with their ends connected to brackets 45 and 41, the brackets 45 being mounted upon the lower bar of the back frame l and the brackets '1 being attached to and depending from the end bars 23 of the frame l5, At the start of the gravityeffected movement of the frames l3 and I9 the springs d5 are relatively loose, that is to say are not under tension. As the outward movement of the frame i9 continues the springs 55 are gradually and progressively tensioned until a degree is reached at which the extension of the frames by gravity will be arrested. At such time the operator inserts his hand under the mattress section at its front side and grasps the front side bar 22 of the section I9, using this bar as a handle and pulling the section I 9 outward to the full permissible extent. ihe section 18 follows the section if! in such movement and at the completion of its movement occupies a horizontal plane in which it is supported by the lower end portions of the guides through the rollers 3! and by the hinge connections 33, all as above explained. The physical effort required to move the mattress sections to their fully extended positions is comparatively slight, due in part to the lightness of the tension of the springs 55 and in greater part to the favorable outline of the path of movement of the rollers 37 of the frame [8, this outline being characterized by the comparatively gentle curvature and forward direction of the curved components 35 of the guides 34 and their merger without any sharp angularity with the lower ends of the straight components 35 of the guides 34.

The mattress section 25 has no movement relative to the frame 5 and participates in its movements during conversion to either phase. There by, through the hinge connection 3 I, the mattress section 25 in conversion to the bed phase exerts a pulling action upon the mattress section 25 with resultant movement thereof relatively to the frame H3 in a direction toward the inner side bar 25. tended the mattress section 25 rests squarely upon the frame H3. The sliding action of the mattress section 25 relatively to the frame [8 may be facilitated by facing the horizontal flanges of the frame bars 20 and 2| with plywood (unnecessary to illustrate). The frame bars 22 and 23 of the frame l9 may be similarly faced with plywood in order to insure the true coplanar relation of the sections 25 and 25 in the bed phase.

In the davenport phase the weight of the frame It and the mattress section 25 which is utilized to initiate the extension movement of the frames is opposed by a suitable latch which positively maintains the parts in davenport relation. When the frames are extended to the limit of their outward movement in the conversion to the bed phase the tension of the springs d5 is opposed by a latch which positively maintains the frames at the outward limit of their extension mover When the frames l3 and I9 are fully exment as shown in Figure 2. The latching action is effected automatically and the unlatching action is effected manually.

The latching elements are operatively connected to a pivotally hung panel board 58 which is arranged at the front of the structure and, as shown, may be coextensive in length with the mattress supporting frame E9. The board 56 is provided at its ends adjacent its upper edge (Figures 1 and 7) with inwardly projecting ears 9 to accommodate pivot pins 55 by which it is connected to the forward ends of the end bars 23 of the frame IS. The board it also has value from the standpoint of appearance in that it extends below the frame is to a line quite close to the casters t2 and thereby, in the davenport phase, conceals the legs 4i and the parts below the frame 59. The board 58 is preferably covered with finishing material of the same and color that is used for the rest of the structure. The pivotal suspension of the board is utilized in connection with the action of the latch mechanism for which reason it is necessary that the board he maintained in a normal plane coincident, as a matter of appearance, with the common plane of the legs 8. This is conveniently accomplished by opposed inner and outer helical compression springs 5i and 52 which are preferably provided in connection with each of the legs 4|. The springs of each pair are respectively arranged adjacent the inner and outer faces of the front flanges of the leg li and are mounted upon a stem 53 carried by and projecting rear wardly from the board 43, the front flange of the associated leg 5! having an opening for the accommodation of the stem and which is of suitably larger diameter. At its rear end the stem carries a washer 54 which is backed by a securing nut. The spring 5! reacts against the washer .54 and the inner face of the front flange of the leg 4| and the spring 52 reacts against the board 48 and the outer face of the front flange of the leg 4|.

In the construction preferred a movable ele ment 55 (Figure 10) is common to both latch mechanisms, this element being of L-shaped outline and having a rearwardly projecting arm 55 and a downwardly projecting arm 5?. The element 55 is pivotally mounted between cars 53 which are carried by the inner or rear side bar 22 of the frame is and project below the frame. The ears 58 are located approximately at the center of the bar 22 and the pivot 59 of the element 55 is located at the elbow formed by the junction of the arms 56 and 5'5. The arm 53 at its lower end is pivoted to a link 55 by which it is operatively connected to the board 53, the opposite or forward end of the link being secured with a measure of loose play to a bracket 5i attached to the board &8 adjacent its inner face. When the board 48 is swung outward from its normal position the arm 55 is lowered about its pivot 59 and when swung inward the arm 55 is raised. The arm 55 is formed for cooperation with keepers 52 and 53 (Figures 10 and 11), the keeper 62 being attached to the lower cross bar of the frame I and providing a shoulder and the keeper 53 being attached to the transverse brace member 5 and provided with a tooth lilze shoulder 65 having its upper surface of inclined cam outline. The arm 55 is provided with a terminal hook 66 for engagement behind the shoulder 64 and with a laterally projecting finger or for engagement behind the shoulder 55. In the davenportphase the arm 55 cooperates with the keeper 62 and when the frames l8 and H! are at the extreme limit of their extension movement during their conversion to the bed phase the arm 55 cooperates with the keeper 53.

In the conversion to the bed phase the seat cushions 44 are removed and the back element 9 is then raised as above explained. Thereupon the operator grasps the lower portion of the board 48 and pulls it outward against the pressure of the springs This outward movement is very slight in degree but is sufiicient to lower the arm 55 (which at that time extends below the shoulder 64) until the hook G6 is moved beyond and below the shoulder 64. Thereupon the frame [8 immediately becomes self-active in initiating the gravity-effected phase of the extension movement of the connected supporting frames, all as above explained.

The element 55 participates in the movement of the frame [9 and as the frame, under the pull of the operator, nears the extreme limit of its outward or extension movement (which is prescribed by the engagement of the rollers 3! against the blocks 38 as shown in Figure 9) the finger 5? (the arm 55 being maintained in a mean position by the springs 52 and 53) will ride over the cammed upper edge of the shoulder 65. As the frame 19 reaches its extreme limit of outward movement the finger 5? passes beyond the shoulder 55 and the arm 55 drops, engaging the finger 6'! behind the shoulder. Thereby both frames are held, in opposition to the tension of the springs 5, at the extreme limit of their outward movement. This relationship is shown in Figures 2 and 10.

The limit of the outward extension movement of the frames I8 and I9 is selected to permit the last step in the conversion of the bed phase, namely the movement of the back element 9 by the operator from its raised position to its fully lowered position in which the wings Ill abut the inclined front faces of the blocks H, the back element in such movement clearing the mattress section 25. The back element 9 is shown in its lowered position in Figure 2 and, with the frames i8 and is held at the extreme limit of their outward movement, a space S intervenes between the rear vertical face of the mattress section and the adjacent lower portion of the back element 9.. This space promotes convenience in arranging the bedclothes. When this has been done the operator effects the final step in the conversion to the bed phase. For the purpose of this final step the guides 34 terminate in relatively short and straight extensional components 68 (Figure 9) with which the curved components 35 merge at their lower ends, the components 58 being substantially parallel to the guides 39. In the final step of the conversion to the bed phase the operator grasps the lower portion of the board 48 and pushes it inward against the pressure of the springs 52. This inward movement is very slight in degree but is sufficient to raise the arm 56 (which at that time extends above the keeper 53) until the finger ii! is moved beyond above the shoulder 65. Thereupon the springs immediately act to effect a rearward movement of the frames i8 and I9 which occludes the space S and is arrested by the lower portion of the back element 9, this rearward movement being sufilciently indicated in Figure 2 by the broken line Y. When the frames [8 and ie have been moved back to the position indicated by the line Y they will assume relative positions in which they are substantially in a common horizontal plane. With the frames positioned as indicated by the line Y the springs 45 will remain under tension and thereby serve an added advantage, viz., of causing the parts of the bedclothing which hang beyond the rear vertical face of the mattress section 25 to be, in effect, clamped with an appropriate degree of pressure between the mattress section 25 and the lower portion of the back element 9.

In conversion from the bed phase to the davenport phase the first step is to pull the mattress supporting frames back to the limit of their outward or extension movement where they are again held by the engagement of the finger 61 with the shoulder 65 of the keeper 63. The back element 9 is then swung from its lowered position to a raised position as indicated in broken lines in Figure 3. The operator then manipulates the board 48 to disengage from the keeper 63 at which time the springs 45 initiate the return movements of the frames l3 and I9. When the tension of the springs 45 decreases to a point where they are no longer effective in moving the frames l 8 and 19 the operator, grasping the front side bar 22 of the frame I9, pushes the frames home, that is to say into the relation shown in Figure 1 and above described in detail. The physical effort required for this operation is comparatively slight, due to the direct application of force by the frame l9 to the frame l8 and the easy movements of the rollers 31 from the lower to the upper ends of the guides 34 and of the frame It with relation to its hinges 33 and the axes of the rollers 31. When the return or folding movements of the frames l8 and I9 have been completed the hook 66, by virtue of the springs 5i and 52, is engaged behind the shoulder 64 of the keeper 52 and'positively latches the mattress supporting frames in their folded relation. During the relative swinging of the frames I8 and iii in the final stage of their return movement the mattress section 26 pushes the mattress section 25. Since the mattress sections have a suitable degree of yielding capacity and their casings are flexible they readily assume the relationship shown in Figure 1 in which the mattress section 25 in effect rests upon the inner portion of the mattress section 26 as a bottom support, the pivot 3| by reason of the yielding capacity of the sections and the flexibility of their casings being shifted to a short extent to meeting points along the inner or then bottom face of the mattress section 25 and along the top face of the section 26. When the supporting frames [8 and I9 are completely folded and latched the back element 9 is restored to its fully lowered position and the seat cushions 44 are replaced upon the mattress section 26.

The invention has been shown and described as a davenport bed for the reason that its use in this capacity will be its principal use. However, in the furniture industry another convertible article of furniture is known as a sleep chair and is an article which can be converted from a chair to a single bed. Generally speaking davenport beds and sleep chairs may be constructed to operate with similar parts and on similar principles. It will, therefore, be understood that the term "davenport is used herein and in the claims as a matter of convenience and with the intent of encompassing a davenport strictly so called or a chair.
