Description:

My current invention pertains to articles of furniture which are readily changeable or modifiable to render them suitable or serviceable for other uses, such, for example, but not necessarily restrictedly, as love seats capable of conversion into beds, the invention, however, being susceptible of satisfactory employment in other or comparable pieces of furniture.

In a specific embodiment of the invention in a love seat, the structure is so made that one end or arm portion of the seat may be drawn out, which action so positions or converts other parts of the theretofore concealed bed into operative relation.

Such a love seat, when in normal constricted or unexpanded position, has two seat-cushions, one on top of the other and desirably practically of the same length reaching from one arm of the structure to the other and one feature of the present invention resides in a construction whereby the movable part of the bed is made sufficiently long to accommodate one of such pair of cushions, preferably the upper one, as its mattress, the other cushion forming the mattress for the companion stationary section of the bed.

Another aim of the invention is to provide a structure of this general character in which the bed, when expanded into usable condition, has no objectionable means making the transverse middle section thereof of any greater degree of stiffness or hardness than the remaining portions of the bed.

A further purpose of the invention is to supply an article of furniture of this type in which the expansible end or arm of the seat is held reasonably rigidly and firmly in the contracted condition of the appliance.

In addition, the invention contemplates the employment or ordinarily concealed locking means for holding the parts of the structure together in its collapsed or condensed status.

To enable those skilled in this art to fully understand the novel invention, both from structural and functional standpoints, in the accompanying drawings, a present preferred embodiment of the invention has been illustrated in detail, and in the several views thereof, for simplicity, like reference numerals have been em50 ployed to designate the same parts.

In these drawings: Figure 1 is a front elevation of the love seat in its normal condition with a portion of the front thereof cut away to more clearly present a part of its inner construction.

Figure 2 is a like elevation of the structure in its expanded bed-forming condition; Figure 3 is a horizontal section on line 3-3 of Figure 2 illustrating the bed in its expanded condition but with the mattress-cushions omitted; Figure 4 is an enlarged end-view of the bedportion only of the article of furniture; Figure 5 is an enlarged vertical cross-section through the structure on line 5-5 of Figure 1; and Figures 6 and 7 are fragmentary detail sections on line 6-6 of Figure 3 and line 7-7 of Figure 4, respectively with the metal bed-fabrics omitted. Referring to these drawings, it will be readily perceived that the love seat includes a suitable back 11, a fixed end or arm 12, a movable end or arm 13, an under seat-cushion 14, and an upper seat-cushion 15 of equal size, but of greater thickness, the top surface of cushion 15 and the bottom face of cushion 14 desirably being made of mattress ticking or comparable or equivalent material, whereas the exposed portions of both cushions in the collapsed condition of the seat are of appropriate material, such as suitable textile fabric or leather, either real or artificial.

A stationary bed-frame is fixedly secured to the end or arm member 12 in any approved manner, such frame at its top including parallel, horizontal angle-bars 16, 16 connected together at their ends' adjacent to the arm-member 12 by a cross angle-bar 17, these three bars carrying a suitable or ordinary metal bed-fabric or springmounted structure characterized as a whole 18, brace-bars 19, 19 being employed at two corners of the frame for strengthening and stiffening purposes.

This stationary frame is supported by four corner legs 21 and 22 having anti-friction domemembers at their lower ends to rest on the floor or its covering.

The pair of legs 21, 21 part-way up their height are connected together by a horizontal angle-bar 23 (Figures 1, 2, 5 and 7) and at the same elevation the two legs 22, 22 at the opposite end of the frame are joined together by a similar horizontal angle-bar 24, the upper, horizontal flanges of these two members 23 and 24 supporting a pair of spaced-apart, guiding, track angle-bars 25, 2ý each having its outer flange directed upwardly and its inner flange horizontal.

The supplemental or auxiliary bed-frame which is secured in any approved manner to the movable end or arm member 13, includes parallel angle-bars 26, 26 secured together at their ends adjacent to such member 13 by a transverse angle-bar 27, braces 28, 28 being employed at such end of the frame and upright legs 29, 29, supporting this part of the construction, the lower ends of the legs having rollers 31, 31 bearing on the floor to facilitate the opening and closing of the structure.

An appropriate, metal bed-fabric 32 is yieldingly mounted on the top of such secondary frame as by helical-springs, as is also the case with the first-mentioned or stationary bedsection.

The other ends of the bars 26 are connected together by a downwardly-bowed or arched bar 33 so that the occupant of the bed will be comfortable and without bearing his weight on such element 33, the metal fabrics 18 and 32 readily yielding downwardly.

Shorter upright legs 34, 34 support the end of such smaller frame 26, 27, 33 remote from the arm or love seat member 13 on the tracks or rails 25, 25, the legs having rollers 35, 35, at their lower ends adapted to travel or ride easily along such tracks.

These legs 34 and their rollers 35, however, are not mounted directly on the frame elements 26, 26, but rather each is secured to a slide 36 (Figure 7) beneath and has a multiple pin or rivet and slot connection 37 with the corresponding bar 26 of such shiftable secondary or smaller frame.

In order to prevent the rollers 35, 35 from running off the ends of their supporting tracks 25, 25, each of the latter at one end is fitted with a stop 38 (Figs. 6 and 7).

To lock the two sections of the bed together in the contracted condition of the structure and with arm-member 13 in place, a latch 4 1 (Figure 7) having a bevelled end 42 is hinged or pivoted at 43 on a bracket 44 mounted on the underside of a transverse angle-bar 45 forming a part of the frame and connecting the legs 29, 29 together, such latch or lock having a tail 46 beneath the lower edge of the depending, vertical flange of the angle-bar 45 to limit the rocking descent of the latch, the latter being pressed downwardly by a suitable spring 47 engaging the angle-bar and latch and coiled around the hingepin 43.

When the undersection of the bed is pushed home within the outer larger bed-section, latch 41 engages and rides over the angle-bar 24 of the fixed frame, and, by cooperation with the inner edge of such bar, releasably locks or latches the two members of the bed together, and, of course, at the same time holds the end or arm member 13 in proper position with relation to the other parts II and 12 of the love seat.

00 Such pivoted lock or latch is manually releasable by means of a cord-loop 48 secured to the latch and extended upwardly through a loop 49 on the inner side of the end-member 13 to a position about midway the thickness of the upper go seat-cushion 15 (Figure 1).

As an additional means for maintaining the seat-end or arm-member 13 more firmly in closed position, springs 51 mounted on the cross anglebar 17 of the fixed frame extend downwardly and securely engage and press downwardly on the top surfaces of the frame-bars 26, 26.

To open the love seat to provide a bed for sleeping purposes, one reaches down between the top cushion 15 and the arm-member 13 and pulls upwardly on the cord 48 to raise and free the lock or latch 41 and at the same time moves the arm-member 13 outwardly.

During such movement of the parts and expansion of the structure, rollers 31, 3i travel easily on the floor or its rug or carpet covering and rollers 35, 35 roll on the stationary tracks and guides 25, 25, the inner end of the smaller auxiliary or secondary frame readily passing out from beneath the two springs 51, 5 !.

When the rollers 35, 35 contact with their limiting stops 38, 38 and the expansion of the structure is continued, the slides which now become stationary allow the movable bed-frame to prolong it outward travel until one of the pins 37 comes to and is stopped by the end of the slot in the slide (Figure 6).

The parts are so constructed and proportioned that the movable bed-frame top-surface is of sufficient length to receive the inverted upper cushion 15 which is swung over and thereby reversed to occupy such relation, the bottom of the upper seat-cushion 15 and the top of the lower seatcushion 14 being desirably hinged or connected together at 52, as by a piece of fabric fastened to the two, to allow such reversal turning of the upper cushion, the latter being enough thicker than the companion cushion 14 so that the top surface of the mattress now formed by such two cushions, one of which has been turned upside down, is substantially flat (see Figure 2). To convert the novel structure back into the original love seat, all one has to do is to swing the cushion 15 up on top of the other cushion 14 and push the end or arm-member 13 inwardly, the result being that the slides 36, 36 collapse first, and, when the member 13 is fully back in place, the movable bed-frame will have been pushed under the confining springs 51, 5! and the latch will have locked the parts together.

One outstanding feature of this construction is that, by reason of the use of the slides 36, 36, the bed can be expanded enough so that in the love seat the two superposed cushions 14 and 15 may be of the same length reaching from arm to arm as portrayed and, in this connection, it should be noted that, in the expanded condition of the structure, the inner end of the withdrawn bedsection is supported solely by said slides and associated parts.

Those versed in this art will readily understand that this novel invention is not necessarily confined and restricted to the precise and exact details of structure and mode of operation hereinabove set forth and that various changes may be resorted to without departure from the heart .and essence of the invention as defined by the appended claims, which should be construed as broadly as permissible by the state of the prior art, and without the loss or sacrifice of any of the material benefits and advantages accruing from uo the employment of the principles underlying the invention.

I claim: 1. In a convertible love seat, the combination of a pair of arm-members, an upper bed-section, G; including a resilient cushion-supporting means. secured at one end to one of said arm-membeP1s and forming the seat of said love seat, a !ower bed-section having a second resilient cushionsupporting means mounted thereon and movable therewith and normally nested beneath said upper bed-section and secured at its opposite end to the other arm-member, said united arm-members and bed-sections being slidable relatively to one another lengthwise said bed-sections by corresponding movement of one of said arm-members to allow conversion of the love seat into a bed, top and bottom normally-superposed seat-cushions for said love seat, each of substantially the length of said upper bed-section and extending from one-arm member to the other arm-member in the contracted condition of the structure, said upper bed-section having a frame with supporting legs adjacent its end opposite its arm-member end and a cross tie-bar at said opposite end below the top of said frame, tracks on said frame parallel to the direction of elongation of the love seat, said lower bed-section having a frame, intermediate-members haing rollers bearing on and adapted to travel on and lengthwise of said tracks, slidable connections disposed lengthwise said bed-sections between the inner end of said lower bed-section and said intermediate-members, each said slidable-connection comprising a slot in the one element accommodating spacedapart pins fixed to the other element, and stopmeans to limit the extent of outward movement of said intermediate-members, said lower-bed section being capable of full withdrawal from beneath said upper bed-section by reason of said slidable-connections allowing further outward travel of said lower bed-section after said intermediate members have engaged said stop-means, said intermediate-members constituting the sole support for the inner en d of said lower bed-section in the completely-expanded condition of the structure.

2. In a convertible love seat, the combination of a pair of arm-members, an upper bed-section, including a resilient cushion-supporting means, secured at one end to one of said arm-members and forming the seat of said love-seat, a lower bed-section having a second resilient cushionsupporting means mounted thereon and movable therewith and normally nested beneath said upper bed-section and secured at its opposite end to the other arm-member, said united arm-members and bed-sections being slidable relatively to one another lengthwise said bed-sections by corresponding movement of one of said arm-members to allow conversion of the love seat into a bed, top and bottom normally-superposed seat-cushions for said love-seat, each of substantially the length of said upper bed-section and extending from one arm-member to the other arm-member in the contracted condition of the structure, said upper bed-section having a frame with supporting legs adjacent its end opposite its arm-member end and a cross tie-bar at said opposite end below the top of said frame, tracks on said frame parallel to the direction of elongation of the love seat, said lower bed-section having a frame, intermediate-members having rollers bearing on and adapted to travel on and lengthwise of said tracks, slidable-connections disposed lengthwise said bed-sections between said inner end of said lower bed-section and said intermediate-members, stop-means to limit the extent of outward movement of said intermediate-members, said lower bed-section being capable of full withdrawal from beneath said upper bed-section by reason of said slidable-connections allowing further outward travel of said lower bed-section after said intermediate-members have engaged said stop-means, said intermediate-members constituting the sole support for the inner end of said lower bed-section in the completely-expanded condition of the structure, and springmeans fastened to said upper bed-section pressing down on the inner end of said lower bed-section in the fully telescoped relation of the bedsections, thereby assisting in maintaining the arm-member of said lower bed-section in position.
