Jackson, Bay Vtnage, Ohimassig'nor to 'lihe mr'vard Manufacturing Company, Cleveland, (Fir-i0, a corporation of Ohio Filed Oct. 6, 1960, Ser. No. 60,893 2 Claims. '(Cl. -17) The present invention relates to slide-out divans and to other furniture and bed constructions, and especially relates to a novel roller carriage unit for association and provision of a movable frame means-in sofa-divans, beds and other similar units,

At the present time, there is increased use being made of multi-purpose beds, -sofas, divans, sofa-divans, and the like. Thus, in many instances, these furniture units are used as divans for seats in the daytime, but with the divan being adjustable so that a portion of the divan can be moved out with relation to the remainder of the divan so that the unit can function as a single bed, or in some instances as a double bed, when desired.

In forming these multi-purpose furniture 'units, it is necessary that asturdy frame means be present in the unit on which the movable frame is well supported for limited, but conveniently available slide-out, or pull-out action to adjust the unit for other use. This multi-purpose unit at the same time must be of uncomplicated design and be adapted to have a long service life with no maintenance thereon.

The general object'of the present invention is to provide a novel slide-out sofa, divan, or the like characterized by the provision therein of a roller supported movable frame in the unit having limited sliding movement with relation to a stationary portion of the frame to change the unit from one intended use over to another use, or function.

Another object of the invention is to provide a novel roller-carriage in an article of furniture of the type described and wherein the roller-carriage is made from a plurality of inverted angles with roller support means being positioned on a floating angle intermediate the top and bottom angles in the slide assembly.

Another object of the invention is to provide a novel and improved slide unit in a sofa, divan or the like and where the slide carriage uses apair of inverted V-shaped angles and with stop means being associated with the movable carriage and support means for the angles to aid in limiting movement thereof on the main frame, and Where the roller means are positioned in the slide carriage in a novel manner.

A further object of the invention is to provide a novel siide unit adapted for use with both single and double beds and Where a pair of the slide units can be carried on a-stationary bedframe and be movable laterally thereof whereby individual sleeping units can be provided on a double bed and with such individual units being readily separated from each other for facilitating making up the beds and with the movable units effectively counterbalancing each other when in use.

Another object of the invention is to provide a novel and improved lineal bearing assembly including'a free floating bearing carriage made from an angularly formed strip containing bearings in each of its angularly opposed surfaces.

The foregoing and other objects and advantages of the invention will be made more apparent as the specification proceeds.

When referring to corresponding members shown in the drawings and referred to in the specification, corresponding numerals are used to facilitate comparison therebetween.

The present invention, in general, relates to the provision in a bedframe, sofa-divan, or the like, of a stationary frame, a movable frame and means securing the movable frame to the stationary frame for movement from a superimposed relation to a cantilever relation thereto, which securing means includes pairs of parallel, inverted, V- shaped angles secured to each of the frames and positioned in nested relation with the angles on the other frame; and roller carriage means including floating, inverted V-shaped roller angles positioned intermediate said angles secured to the frames, and roller members journalled on the roller angles for load support and transfer action between the frame angles.

Reference now is made to the details of the structure shown in the accompanying drawings, and a sofa-divan of the invention is indicated as a whole by the numeral 1. The sofa-divan 1 includes a stationary frame 2 having a plurality of support legs 3 and suitable boister means 4 may be secured to and be supported on the stationary frame 2, as by means of bolster supports 5. FIG. 2 and FIG. 3 of the drawings both bring out the fact that the bolster means 4 are positioned above and spaced from the other elements in the stationary frame 2 and a movable frame 6 is provided in the sofa-divan and is slidingly supported thereon by suitable means. Hence, the movable frame, as hereinafter described, can be pulled forwardly of the sofa-divan to extend from the stationary frame 2 as a cantilever, and with the movable frame being movable back into a substantially superimposed relationship to other portions of the stationary frame when desired, as indicated in FIGS. 1 and 3. Normally the movable frame 6 should be longer than the stationary frame 2, asis best shown in FIG. 2, and the support legs 3 are recessed from the margins of the sofa-divan. This movable frame 6, as shown in FIG. 6, includes a front rail 7, and a rear rail 8. Normally the front rail 7 has a downwardly extending leg and a horizontal leg 7a and 7b1thereon, respectively, while the rear rail 8 has an upwardly extending leg 8a and a horizontally extending leg 812.

It is a feature of the invention that novel and improved support means have been provided for positioning the movable frame ti on the stationary frame 2 for convenient, readily controlled movement therebetween from a divan, or seating position to an extended, or sleeping position. These means are shown in figures, such as FIGS. 4, 5, 6 and 9, and include a plurality of substantially inverted V-shaped angles positioned in nested relationship with each other. The supports, or support means for the movable frame 6 include at least two sup- 'port 9 suitably secured and extending from front to rear of the stationary frame 2 in parallel relation to it other. PEG. 6 of the d.awings best brings out that the stationary frame may be made from angle means with horizontal legs 2:: and dependent, or downwardly extending legs 25, as shown, and that the angles 9 are attached to the le s 2a by welding or by bolting through a mounting plate 2.9 welded to the leg extremities of the angles 9. The movable frame 6 has a pair of supported angles secured through and extending between the front and rear rails 7 and 8 of the movable frame in properly spaced relationship for. nesting engagement with the support angles 9. -hese supported angles 10 are shown secured to the movable frame by means of downwardly extending brackets 12 and 13. FIG. 6 best shows these brackets 12 and 13 and that the bracket 12 is secured to the horizontal leg 71: of the front rail and extends downwardly therefrom to be attached, for example, by a bolt 14, to a stop plate 15 secured, as by welding, to the front end of each of the supported angles 10. The bracket i3 likewise is welded to the lower surface of the horizontal leg 2b of the rear rail of the movable frame and extends downwardlytherefrom to be, for example, bolted to the carrier plate 16 which is welded to and extends transversely of the supported angle 1%) at the rear end thereof. Such carrier plate 16 is provided with a V-shaped notch 17 "so that such carrier plate 15 does not extend across the rear open end of the supported angle it) but permits forward movement thereof, as hereinafter described. Naturally, the bracket 12 and the stop plate 15, or the bracket 13 and carrier plate 16 may be formed as single angle brackets with the downwardly extending leg of the rear bracket notched out, as at 17, and welded to the supported angle 1%}. The horizontal leg of the angle bracket may also be provided with bolt holes for attachment to the horizontal legs 7b and 8b of the movable frame 6.

As a feature of the invention, a novel and improved roller carriage assembly is provided by the present invention to position the movable frame 6 for convenient, read .ily controlled, sliding action on the stationary frame 2. Such roller carriage includes a roller angle 18 freely, or hoatingly positioned intermediate each of the pairs of support angles and supported angles with all of such angles normally being of the same size and contour for convenient nesting engagement therebetween. These roller angles each carry a plurality of rollers 19. In order to position these rollers 19 on the roller angles 18, a plurality of slots or openings 29 are formed in the roller angles and with the rollers 19 being in such slots. The rollers I? are of a diameter as to protrude both vertically upwardly and downwardly from the associated support surfaces of the roller angles 18. These rollers are suitably journalled on pins or shafts 21 that are secured to the roller angles by special means thereon. For example, the pins 21 are very effectively secured to the roller angles 13 by stamping, or punching portions of the roller angles adjacent the slots in opposite directions. Thus a pair of integral, upwardly extending retainer bars or straps 22 are formed in each leg of the roller angles 18 adjacent each of the slots 20 and a pair of downwardly extending straps 23 are formed in each leg of the roller angles and integrally therewith. The straps 22 and 23 are arranged so that the pins 21 are firmly positioned to 3'ournal the rollers 19 with their longitudinal axes extending normal to the longitudinal axes of the roller angles 18; The lower ends of the pins 21 may bear against marginal portions of the strap openings or slots to prevent axial movement of the pins. 3

The supported angles and roller "angles of the invention are restricted in their vertical movement with relation to each other, as by means of a U-bolt, or equivalent member 24, SCured to the front rail 2a of the stationary rail 2a through the mounting plate 29. Adjacent the.

rear ends of each of the support angles 9, a similar U- bolt 25 is secured over the nested angle assembly and is retained fixedly in engagement with the support angle 9, as by means of a cross bar or plate 26 extending under and fixedly secured to the lower edge of the support angle 9. The position of the U-bolt 25 from the rear member of the stationary frame 2 will limit the outward movement of the movable frame member 6, by providing a stop against which the carrier plate 16 will abut. A slight clearance between the U-bolt 25 and the exterior surface of the supported angle 18 is provided to permit movement therebetween during the reciprocating motion of the movable frame member 6. At the extreme outward position of frame member 6, the U-bolt 25, in contact with the supported angle 10, supports the frame member 6 against tipping and provides a stable cantilever structure. However, the U-bolts 24 are slightly larger in a vertical direction than the roller assembly whereby a limited lifting movement is permitted for the front end of the movable frame 6 when starting to pull the movable frame 6 out to a cantilever relationship with the stationary frame 2. Such limited vertical movement of the movable frame 6 permits lock fingers 28 that are secured to the supported angle 10 to be lifted up over the mounting plates 29 positioned on the stationary frame 2 when the movable frame is pulled out from its retracted position. When retracting the movable frame, the lock fingers 28 will ride up over the lock plates 29 and drop behind them to be effectively retained in retracted position, as long as no forward movement thereof is needed.

Associated with the support angle 9 is a stop plate 35 to arrest the'roller angles 18 which float horizontally between this stop plate and the stop plate 15.

It will be realized that any suitable number of the rollers 19 may be used and that they are provided on both legs of the roller angles to furnish effective resistance against downward and sideward forces. Such cylin drical rollers have been found to be particularly effective in providing smooth support for the movable carriage. It also will be noted that the roller angle 18 may be of lighter gage than the other angles. 7

*FIG. 12 shows a modified use of the slide-out or roller carriage means of the invention, as applied to a bedframe. Thus a double bed 30 of substantially conventional construction is provided and it includes a pair of longitudinally spaced cross rails 31, only one of which is shown in the drawings, and with suitable longitudinally extending or side rails (not shown) also being provided in the bedframefii. In extra width beds it is quite possible'a center support member would be applied to the center of the frame. In all events, the bedframe 30 is a suitable support member of sufficient width to accommodate two twin-bed spring and mattress assemblies arranged side by side While each half of the support member is adapted to have a pair of the roller carriage or movable carriage units 33, similar to the movable carriage and frame means 6 of the other figures of the draw ings, operably associated therewith. Such movable carriage units would comprise the three nested angles and associated means as previously described. Each of the crossrails 31 would have a center stop plate 32 provided thereon and these movable carriage units 33 would be attached to and associated with the cross rails 31 on opposite sides of the stop plates 32. Thus any suitable spring and mattress means 34 can be carried by the movable carriages 33 and be moved laterally outwardly of the bed frame 39, when desired. The movable carriages 33 can be separated when the beds are to be made, and the movable carriages can be either retained in their adjacent positions for sleeping action, or else be pulled laterally outwardly of the bed when desired. The movable carriages 33 will effectively counterbalance each other when pulled out to extended, cantilever sleep positions.

However, the cross rails 31, FIG. 12, may be of inverted V-shape in section to form the lower members in the movable carriage assembly, if desired.

From the forgoing, it will be see that the slide carriage means in the divan, or other article of the invention can be readily moved from a seating position out to an extended sleeping position, or that separating movement of twin sleeping units can be obtained. The slide carriage and mociated means are of novel construction and of good operative properties. Hence the objects of the invention are believed to be achieved.

While two complete embodiments of the invention have been disclosed herein, it will be appreciated that modification of these particular embodiments of the invention may be resorted to without departing from the scope of the invention as defined in the appended claims.
