,8 Claims. 1

This invention relates to bed construction, and more particularly to the provision of twin beds which may be used independently, but are capable of being nested together in order to occupy a minimum of space with one of the beds concealed.

-It is an object of the invention to provide twin beds which will afford comfort to the occupants and which can use mattresses of any desired thickness so that they will be as comfortable as other ordinary beds, and which may be nested for compactness, and which may be made ready for immediate use upon a moments notice.

`It is a further object of the invention to provide twin beds which may be made up ready for use prior to their beingnested and which may be separated, and the actual simple pulling apart or act of separating of the beds will cause the inner bed to automatically rise to the full height of the outerbed so that both beds may be immediately occupied.

A further object of the invention is to provide practical and substantial twin beds of the above described character of simple, durable and economical construction, and which will improve the appearance of the room in which they are used.

A further object oi the invention is to provide mechanism for the collapsing of the inner bed, which. may bemanipulated by a lever and by applying a smallramount of Weight upon the same.

Further objects and advantages of my invention will be apparent from the following specification taken in conjunction with the accompanying drawings, wherein:

Figure 1 is a perspective of the beds in separated relation;

Fig. z, a perspective of a portion of the working parts;

Fig. 3, a section through the framework of the beds in side by side relation;

Fig. 4, a bottom plan of the beds nested without the mattresses;

JFig. 5, a vertical longitudinal section `er the nested beds without the mattresses;

Fig. 6, a top planview of thenested beds Without the mattresses;

Fig. 7, a longitudinal section of the inner bed supported in operative position without the Inattresses and springs; `and Fig. 8, a `bottom plan of the beds devoid of mate tresses in side by side relation disclosing particularly the release mechanism for causing the inner Abed to'assume its operative height,

Asshown in Fig. 1, twin beds are provided with mattresses I0 and Il, and frames I2 and I3. The

mattresses Ill and II are of conventional, prefere` ably inner-spring, construction to aord maxle mum comfort to the user. The mattresses I0 and II may be of similar dimensions, although if 1de: sired the mattress Ill may be slightlysmaller in length and width.

The frames or bases I2 and I3 are designed pri;-l marily for their supporting function, vas is true of the base of any bed, but they are also designed for pleasing appearance, both when nested 'or when they are separated. Theyare likewisedef signed to simulate a single bed when they are in nested relation. Theseframes or bases are `also designed to provide maximumcompactness, `as Well as simplicity in the nesting of the same in addition to their supporting functions. The frame I3 forms ahousing or outer casing'for the frame I2 and its mattress. Rollers I4 are mounted within the plane of the end memberof the frame I3, therefore olering no obstruction interiorally or exteriorally of this frame, and at the same time the frame can readily be rolled'only in a` sidewise manner. The inner bed, whichincludes the frame I2, has its rollers I5 mounted on the lower ends of the legs I6 at right angles to the rollers of the other bed, andtherefore the inner bed can only be moved in an endwise direction. Thus, when the beds are being nested the inner bed having the frame I2 is moved endwise to position beside the other bed, having the frame I3, which forms the housing. This housing is moved laterally to bring the beds into nested relation. The inner extremities of the ends of the frame I3 are provided with bevelled felt-covered surfaces I'I in order to prevent the corners of the inner bed from being marred, and in order to cause automatic alignment by the movement of the inner bed endwise if necessary in assembling.

As shown in Fig. 1, when the beds are readyfer occupancy they are of the same height. However, in Qrder toacc'ommodate the thick mattress I0, it is neeessary for the bed which nests inside of the other to collapse suiciently to permit this nesting to be accomplished. Therefore, the innerl bed has a narrower frame I2 than that of the other er outer bed` frame, and pivoted legs I6 carrying the rollers I5 at their lower extremities Vserve to support the bed in both its `lowered and elevated positions- The frame I2 of the inner bed is rectangular, and has two pairs of legs IS, one pair at each end. The legs of each pair are connected adjacent their `lower extremities by means of a-braee I3 `of angle iron to make Vthem of relatively streng,

rigid construction, and the upper extremities of said legs are likewise reinforced with cross braces I9. The legs I 6 are fastened by bolts and nuts 26 to brackets 2| attached to the side members of the frame I2. These bolts form the pivots about which the legs swing. The upper extremities of the legs I6 are connected by pivots 22 with links 23, at one or both sides of the bed (only one being shown), which links at their opposite ends are provided with pivots 24 connected to the opposite extremities of a crank bar 25 pivoted at its center on a bolt 26 so that throwing or rotation of the crank bar 25 about the pivot 26, when the legs are depending in supporting position, when the bed is in elevated position, will by means of thev links 23, swing the lower extremities of one pair of legs slightly away from the other pair, thereby permitting slight pressure on the bed to Vdepress it to collapsed position. The pivot 26 is mounted in a plate 21 counter sunk inside of the bed frame I2, and a lever 28 having an operating knob on its free end is also pivotally mounted on said plate 21. The lever 28'oscillates ina slot 28 in the inner surface of the side frame of the bed. This limits the throw of the lever from the locked position of Figs. 2 and 7, clockwise only, sufficient to move the pivot 24 beyond dead center. This moves the upper ends of the pairs of legs toward each other and spreads the lower portions of said pairs of legs apart initiating collapse of the legs so that weight will cause them to move to fully collapsed position. When the free end of this lever is raised the'pivot 24 is engaged thereby and the bar 25 is swung on its pivot 26, to cause the release of the legs. Weight of the 'bed and the application of slight pressure will cause the legs to swing apart at their bottoms to permit the bed to be lowered. The lever 28 is provided with a notch 29 for receiving one of the pivots 24, and due to the fact that the pivoted end of the lever 28 is mounted slightly eccentrically of the pivot 26, when the pivot 24 is engaged by the notch 29 the locking action will be accomplished, thereby maintaining the legs in upright position. When the bar 25 is in the position shown in Fig. 2 it is slightly beyond dead center, being limited as to further movement in a counter-clo-ckwise direction by means of the lever 28 against which the nearer pivot 24 engages so that there can be no possible accidental lcollapsing of the bed. However, when the lever is swung upwardly the bar 25 is rotated beyond dead center in a clockwise direction. This movement of the levers swings the upper ends of the legs toward the center of the beds and the lower extremities of the legs away from the center of the bed and .permits it to be forced downwardly. The spring 30 connects one of the links 23 to the bed frame, thus tending to maintainthe connecting links 23-23 and bar 25 beyond dead center.

Spring means is provided for normally bring- .ing the legs I6 into dependingoperative, sustaining, position. Such spring means includes a main connecting spring 3|, connecting the centers of the reinforcing braces I8 so that when vthe legs are released the spring 3| contracts to pull the lower extremities of the legs toward operative position, and in like manner springs 32,

connecting the upper ends'of the braces I9 and the ends of the bed, pull the upper ends of the legs toward the ends of the bed, thus assisting the spring 3|. The springs 3l and 32 are of sufficient strength and under sumcienttension to overcome the weight of the bed structure and 4 lift the same when the legs are released when in collapsed position.

Stops 33 (Fig. 7) are adapted to be engaged by l the braces I9, and thus limit the swinging of the lower extremities of the legs toward each other when the legs are in supporting position, while stops 34 are engaged on their under sides by the legs I6 when they are collapsed as shown in Fig. 5, thereby limiting the collapsing movement of the legs.

In order to fasten the legs I6 in collapsed position, swinging latches 35 on pivots 35, are pivoted to mounting bars 37 attached to the under side of the frame cross bars 38. Rollers 45, mounted on the cross bars provide bearing means for the latches 35. These latches 35 have beveledtoe portions 35 adapted to be engaged by the leg braces i8 so that these leg braces ride under these toe portions of the latches, and the legs are held in collapsed position. The extrem-V ities of the latches, remote from the toe portions 35' are adapted to be engaged and operated for releasing the legs to permit the bed to attain its proper elevation under the influence of the springs 3| and 32, and this operation can be accomplished manually by a kick of the toe or foot, or otherwise. Similarly the latch 35 can be operated by a lever, hereinafter described, on the other bed section. Springs 39 maintain the latches 35 in latching position.

In order to cause simultaneous release of the latches 35, links 4l) are attached to opposite ends of a bar 4| pivoted in the frame at 4I. Movement of this bar in a clockwise direction (Figs. 2 and 6) will retract the latches to release the legs. Reverse movement is automatic on account of the springs 39.

The lower extremities of the beveled felt-covered surfaces I 'I of the outer casing have mount ed therein spring pressed detents 42, on pivots 43, under the inuence of the springs 44. Each of these detents engages a section of the frame so that it can only move in a limited arcrfrom a position `substantially in alignment with the end of the frame I3 to a position at right angles thereto across the line of movement of the inner bed frame I2, and directly in the path of movement of the latches 35. Y

Thus when the beds are brought into nested relation the detents 42 are collapsed against the action of the springs but when they are moved in the opposite direction they trip the latches 35, just as the beds are separated and the inner bed automatically assumes its full height on the legs i6 due to the action of the springs 37| and 32. This height corresponds to that of the other bed.

The lever 26 and associated linkage locks the legs in fixed relation until the lever is swung upwardly, whereupon as previously stated the weight of the bed and slight pressure by an individual will cause the bed to assume its lowermost position, and the braces4 i8 connecting the legs at their lower extremities ride beneath the toe portions of the latches 35 and are heldin this position until these latches are released, atv
