The invention herein disclosed is known under the trade name Hassock-bed" and comprises a new article of furniturewhichcanbeusedeitherasabedorasahassock,and be converted at will from the one type of furniture into the other. 7

Special objects of the invention have been to enable the quick and easy conversion from the one form of furmture into the other and to have in each instance a fully useful and practical structure, that is, the bed in the one instance and the hassock in the other instance.

More specifically it has been a purpose of the invention to enable the conversion to be accomplished practically in a single continuous operation, the hassock to be opened out into a bed in a continuous unfolding operation and conversely, the bed to be changed back into a hassock by a simple and practically continuous folding and closing operation.

Special objects of the invention also are to so counterbalance the parts that only slight efiort will be required to effect the unfolding and folding operations.

It is a purpose of the invention also to insure that the parts will be firmly and securely locked in the closed or folded condition, but in such a way that they may be quickly unlocked when the conversion from hassock to bed-forming structure is to be made.

Other important objects of the invention are to accom plish all the foregoing with a relatively simple and low cost form of construction.

Other desirable objects and the novel features through which the purposes of the invention are attained are set forth or will appear in the course of the following specification.

The drawings accompanying and forming part of the specification illustrate apresent practical embodiment of the invention but structure may be modified and changed as regards the immediate illustration, all within the true intent and scope of the invention as hereinafterdefined and claimed.

Fig. 1 in the drawings is a perspective view of the invention in the form of and use as a hassock;

Fig. 2 is an enlarged side elevation of the folded hassock-forming structure as it appears after the hassock slip cover has been removed;

Fig. 3 is a side elevation showing the parts in the unfolding or opening operation;

Fig. 4 is a similar view showing the parts completely opened out into the bed-forming relation;

Fig. 5 is a broken plan view of the same; 7

Fig. 6 is a vertical cross sectional view with parts appearing as on substantially the'plane of line 66 of Fig. 0

2 t may be shortened for use as a child's bed, by folding under the end frame section and placing a bed or crib-forming .frame about the shortened frame structure; f" Fig. I0 is a side elevation of the parts in this latter conproviding the child's bed;

Fig. 11 is a plan view of the folding frame which can be attached to form the sides of this bed;

Fig. 12 is an enlarged broken sectional detail showing how the folding frame may be secured to the headboard. Fig. 1 shows the invention in use as a hassock, with 'a slip cover 15 over the cushion 16 which forms the top of the folded hassock-forming structure shown in Fig. 2.

This single cushion 16, in addition to providing the top of the hassock, cooperates with a foldable, double cushion 17, as shown in Figs. 3 and 4, to provide the complete, full length bed mattress.

These coextensive mattress-forming cushions are mounted so that the double length cushion will automatically unfold and line up with the single cushion as the latter is lifted and will automatically fold up beneath the single cushion as the latter is returned to position over the hassock base.

The base of the hassock, last referred to, is indicated in several views as a substantially rectangular frame 18 to rest on the floor, having a pair of upright posts 19 at the rear corners which become the head of the bed, and a pair of shorter upright posts 20 at [those] the from corners which are located intermediate the length of the bed.

The latter posts provide the pivotal supports for-the hingedly connected frames 21, 22, which carry the folding sections of the double mattress cushion.

The [outer or end] inner frame 21 is shown pivotally connected with the [inner or] intermediate frame 22 by hinge links 23 having the pivot connections 24, 25, at opposite ends.

These double jointed hinge cushion to fold smoothly, as cramping or squeezing. The [end] frame 21 is shown supported at the [outer] rear end by toggle links 26, 27, pivotally connected together at the center, at 28, and pivoted at the ends, at 29, 30, to [end] frame 21 and to the base, respectively. The center pivots are shown connected by links 31 to pivot pins 32 on the ends of levers 33 which are pivoted intermediate their ends at 34 on posts .20, and have their opposite ends pivoted at 35, underneath frame 22 at the far side of the hinge pivot 25.

As a result, the lifting and unfolding operation of the intermediate frame 22, as shown in Figs. 3 and 4, will impart a straightening action to the toggle links 26, 27, to lift the [outer] rear end of [end] inner frame 21.

At the same time, the [inner] from end of this frame is guided up into horizontal position by links 36 engaged with pivots 34 on the posts 20 and pivotally connected with the [inner] from end of the frame at 37.

In the fully extended, horizontal relation shown in Fig. 4 the [end] inner and intermediate frames 21 and 22 are locked by

toggle links

38, 39, pivotally connected together at the center at and pivoted at their outer ends at 41, 42, with downwardly angled extensions 43 of the frame 21, and with frame 22. This toggle linkage and interlocking relation prevents breakdown of the hingedly connected frames under application of undue or excessive pressure. I

The downwardly inclined extensions 43 for the connection of

toggle links

38 and 39 cause these links to break connections enable the shown in Fig. 2, without at the center connection 40 as the bed starts folding from the Fig. 3 to the fully folded, Fig. 2, position.

The frame 44 for the single top cushion 16 is shown as [pivotally] hingedly connected at 45 with the intermediate frame22 so as to fold over and carry cushion 16 over the top of intermediate frame 22 as the three frames are hinged over each other from the Fig. 3 to the Fig. 2 position.

The [outer] front ends of intermediate frame 22 and end frame 44 are supported by

leg members

46 and 47,

, the latter rigidly secured to frame 44 at 48 and the former fold the pivoted legs 46 in the reverse, folding operation,

as indicated in Figs. 3 and 2.

In the completely folded condition, upwardly projected, angular extensions 53 of legs 46 engage in projecting brackets 54 on posts 19 to aid in locking and securing the parts in fully folded relation.

To lock the inner or intermediate set of legs 46 against collapsing tendency, the outer frame member 44 is shown provided with dependent lugs 55 to bear upon the [leg extending struts] links 50 in the fully extended position of the parts shown in Fig. 4.

The three hingedly connected frames 21, 22 and 44 are shown in Fig. 5 as carrying suitable mattress supporting springs 56 foldable on the hinging lines, so as not to interferewith the free folding and unfolding operations de- To further facilitate the unfolding and folding operations the parts are balanced and counterbalanced in the illustration by elongated helical springs 57 connected between an intermediate lug 58 on the end of [end] frame 21 and [outer] corner posts 19, Figs. 5 and 6, and a spring 59 connected between this lug and the mid-portion of the base at 60, Fig. 3. Other extension springs, 61, are shown connected between the end pivots 32 of levers 33 and anchorage points 62 in the [outer] rear corners of the base.

These springs have the effect of partially supporting having the center pivot 19 connected by link so with the center pivot 28 of the inner frame raising and lowering toggle links 26, 27.

Figs. 2, 3 and 4 show successive positions and operation of headboard 73.

The hinge center 74 for the headboard is located at the [inner] rear end of frame 21 and at a height approximating the thickness of the mattress pad 17, so that in the folded relation shown in Fig. 2 it will lie flat between the folds of the pad. In the unfolding relation the frame 22 lifts away from the lowered headboard, as shown in Fig. 3, before the linkage described becomes efiective to raise the headboard. Finally, as the parts become fully unfolded and straightened out in the horizontal relation shown in Fig. 4, the

linkage

26, 27, 80, 75 and 76, will pull the headboard into upright position, the parts locking in this relation by the toggles 26, 27, reaching or passing dead center relation.

lhe reverse action takes place in folding from the bed tothe hassock-forming condition, it being noted particularly in Fig. 3 that the headboard 73 will be folded down into holding position over the mattress pad 17 beand counter-balancing the pivotally mounted frame sec- 'tion's, enabling the latter to be smoothly and easily drawn up out of and returned to relatively folded relation in the base.

The parts are preferably [balanced so as to be] biased in the folding direction, and in addition'it has been found desirable to lock and secure the structure in the closed,

folded condition.

The locking mechanism is shown as consisting of a rod 63, Figs. 2, 7 and 8, journalled in 64 beneath the [outer] front end of the outer or upper frame section 44, carrying at the center a hook 65 engageable with a catch 66 attached to the hinge links 23 connecting the inner and intermediate frame sections 21, 22. A spring 67 connected with an upward extension 68 of the hook tends to rock the hook into engagement with the catch or keeper, the extent of the spring movement being limited by the stop 69, Fig. 8. Movement in the opposite direction is limited by a front stop 70 engageable by hook 'into the extended relation.

A headboard 73 is shown pivoted to the [inner] rear endoftheinnerframe2l,at74

- This headboard is automatically raised and lowered in 'theopeningandclosing operations andisfurtherutiliaedto assist in folding and holding the double length cushion 17 by the provision of

toggle links

75, 76, pivoted at the endsat77,78,totheheadboardandtoframe21and fore that pad reaches the doubled-up condition, resulting in finally foldedcondition shown'in Fig. 2.

e lowering of the three spring frames 21, 22, 44, into the base-forming frame 18, as shown in Fig. 2, is of special advantage in that it reduces the over-all height in the folded position to a convenient and comfortable seating height for a hassock, andthis compacted or condensed relation of the parts avoids any waste space.

The folded structure, therefore, is as small and compact as may be desirable for a hassock, and this is accomplished without reducing the overall dimensions of the bed, for the three folding sections of the hassock will provide the frame ofafullsize bed.

It will be clear from the foregoing that in the folded relation shown in Fig. 2 the parts are securely locked by engagement of leverage extensions 53. of intermediate pivoted legs 46 with the catches or keeper lugs 54 on the sides of posts 19, and by engagement of book on the upper or outer frame section 44 with catch 66 on intermediate frame 22.

In this condition the device provides a substantial, practical hassock-forming foundation with a top cushion 16 and may be used for general hassock purposes.

Instead of an ornamental slip cover such as shown in Fig". 1, other covers maybe employed, such as a cover simulating the appearance of a wall cabinet or stand, and which could be applied with the folded device standits side instead of resting on the bottom. The locked condition permits of this turning the device on its'side, enabling it to be placed againsta wall and used as a table, or to be stored in this position in a closet or the like. Casters or feet may be provided on the base frame for supporting it flat or on edge and to aid in about. To unlock and extend into bed-forming position, the locking rod 63, Fig. 7, may be grasped by the handles 72 and turned to rock the book 65 out of engagement with catch 66, and then these same handles be used to pull out the top and intermediate frame sections 44, 22, through the Fig. 3 position to the fully extended relatio shown in Fig. 4.

As shown in Figs. 9 to 12, the outer or top flame sec- 10 tion 44 may, if desired, be swung in under the intermediate frame section 22, about the connecting pivot 45, thus shortening the bed structure to the combined length of the hingedly connected sections 21 and 22, amounting to the length of the double or foldable mattress pad A removable side flame may be used in this partially extended condition, the same beingshown as made up of side boards 81, hingedly connected at their ends at 82 with end boards 83 hinged together at 84.

Legs 85 are shown pivoted to the side boards at 86, in position to swing down over the outer end of frame 22, and which frame has screw seats 87 to receive the thumb screws 88 or like fasteners which can be passed through the openings in the legs into the end of the frame to support this end of the frame and to secure the legs in upright position.

At the other end the side boards 81 are shown secured to .the headboard 13 by angle plates 89 reaching around the edges of the headboard and through which thumb screws or other fasteningsM are passed into the headboard. I

The

folding frame

81, 83, is quickly attachable and detachable and may be easily applied to convert the partly unfolded structure into a shortened bed or crib such as shown in Fig. 9.

The invention has the advantage of automatically extending the mattress out into flattened condition, ready for use, in the simple act of opening and unfolding the connected flames, so that there are no heavy operations of separately handling the mattress. The mattress pads are attached to the frame sections so as to move therewith. The fastenings for the purpose may be in the nature of tapes or the like, so that the pads may, when desired, be readily removed for cleaning or replacement. I

The motions of the mattress carrying frames are substantially counter-balanced so that very little effort is required in the .extending and folding operations. The

parts fold naturally and easily into position, one over the other, it being noted that levers 33, pivoted on the base, support the inner end of the intermediate frame 22 andalso,asthepartsarelowered,servetoswingthis frame inwardly into alignment over the "lower, inner flame member.
