Cl. -136 13 Claims ABSTRACT OF THE DISCLOSURE A storable bed is of the type comprising a base frame, a bed frame that swings about a first pivot axis between a vertical stored position and a horizontal sleeping position, arm means which are pivoted to the bed frame about a second pivot axis and counterbalance springs acting between the bed frame and the arm means; the arm means carry bed clothes retaining means that clamp the bedclothes to the bed under the action of the counterbalance springs as the bed frame approaches the stored position, a connection between the arm means and the base frame permitting operation of the clamping means only while the bed frame is a predetermined distance from the stored position.

CROSS REFERENCE TO RELATED APPLICATIONS This is a continuation-in-part of my application Ser. No. 557,690, filed June 15, 1966, now abandoned.

BACKGROUND OF THE INVENTION This invention is concerned with improvements in or relating to beds of the vertically stored type, that is to say, beds of the type which can be moved at will from the usual horizontal sleeping position to a vertical stored position in which they occupy less floor space Such beds may be provided, for example, in a socalled bachelor or bed-sitting room apartment, mounted in a closet into which it can be swung during the daytime and concealed with suitable curtains or doors. In other arrangements the bed may, for example when in the vertical position, be disguised as a piece of furniture (e.g. a wardrobe) or a part of the room itself (e.g. a chimney piece).

The design of such beds presents a number of problems. For example, they should remain positively in the vertical and horizontal positions when placed there, and yet must be provided with some counterbalance means that are sufficiently effective for the bed to be moved safely and easily by one person, who may be elderly and have little strength. In practice the bed must be provided with some means for retaining the bedclothe in a fully made-up position while the bed is vertical, so that it can be made in the morning, swung to the vertical position, and will not require to be remade when returned to the horizontal position. In particular, the bed should be inexpensive and yet attractive in appearance, with the operative mechanism concealed to the maximum extent.

It is an object of the present invention to provide a new bed of the vertically storable type wherein the counterbalance springs are also effective to operate bedclothes retaining means.

SUMMARY OF THE INVENTION In accordance with the present invention there is provided a bed of the vertically storable type comprising a base frame, a mattress-receiving bed frame pivotally mounted on the base frame about a first pivot for movement between a horizontal sleeping position and a generally vertical stored position, arm means pivoted to the said bed frame about a second pivot between a first position corresponding to said bed frame sleeping position and a second position corresponding to said stored position, bedclothes retaining means carried by said arm means and movable thereby upon corresponding rotation of the arm means about the second pivot between a stored position in which it is generally parallel to the bed frame for retaining engagement with bedclothes on the bed and a sleeping position corresponding to the bed frame sleeping position, spring means providing a bed counterbalance force for the bed and a clamping force for said bedclothes retaining means, means connecting said spring means to the said arm means and the bed frame so that the spring force thereof acts between the arm means and the bed frame to rotate the arm means about the said second pivot to move the bedclothes retaining means towards the bed frame and thereby apply the said clamping force thereto, and also to urge the bed frame for rotation about the first pivot from the sleeping position toward the stored position, and constraining means connected between the base frame and the said arm means for constraining movement of the arm means after a predetermined movement of the bed frame away from the stored position toward the sleeping position, whereby upon further movement of the bed frame toward the sleeping position the bedclothes retaining means are constrained from movement with the bed frame and are thereby disengaged from their clothes retaining relation with the bed frame and retained in their corresponding sleeping position.

DESCRIPTION OF THE DRAWINGS Vertically storable beds which are particular preferred embodiments of the invention will now be described, by way of example, with reference to the accompanying drawings wherein:

FIGURE 1 is a perspective view of one side of the top end of a first embodiment, the bed being shown in its lowered position,

FIGURE 2 is a side elevation with the bed of FIG- URE 1 in the lowered horizontal operative position,

FIGURES 3 and 4 are views, generally similar to FIG- URE 2, showing respectively the bed in an intermediate position and in a stored vertical position, and

FIGURE 5 is a view similar to FIGURE 1 of a second embodiment.

In all the figures of the drawings parts thereof are broken away as necessary to show the internal structure and operation of the bed. Similar parts are given the same reference in all the figures of the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The bed is mounted on a floor 10 by means of a U- shaped base frame of angle iron, comprising a back member 11 and two side members 12, the base frame being securely fastened to the floor as by bolts or screws 13. Decorative side panels 14 are fastened to the side members 12 and conceal the operating mechanism.

The bed frame 15 which receives a conventional box spring 16 and mattress 17 is illustrated as comprising two angle iron side members, a generally z-section end member, and tubular cross members 18, the side members being separable at 19 intermediate their length to permit the bed to be compactly packaged for storage and transport. The top ends of the spring and mattress abut against the top member which has forwardly-extending side members 20 fastened thereto, the

side members

15 and 20 being spaced apart, as by a web 21 (FIG. 1), to provide space for entry of the hand in manipulating the bed clothes. A respective box structure 22, open at its vertical rear edge 23 is securely fastened to each side member 20. A pivot pin 24 extends from the outer side face of the structure 22 and engages in a trunnion 25 carried by a vertical post 26 securely fixed to the respective side member of the base frame 12. It will be seen that the weight of the bed frame is supported on the pivot pins 24, and that it is capable of free pivoting movement thereon, between the said vertical stored and horizontal sleeping positions. In the horizontal position the weight of the bed frame is also supported by a pair of legs 27, which are pivoted to respective side frames near to the bottom ends thereof. Each leg has one end of a tension spring 28 connected thereto, the other end of the spring being connected to the respective bed frame side, the connection being such that the spring must be extended to move the leg from both the supportive position (FIG. 2) or the stored position (FIG. 3), and therefore will not permit the leg to remain in an intermediate position.

A pivot pin 29 extends from each side member 20 within the box 22 and has the end of one arm of a Y-shaped member 30 pivoted thereto. The foot of each Y-member is connected to the frame by constraining means constituted by a respective flexible connection, which in this embodiment comprises a chain 31, while the end of the other arm is connected by a pivot 32 to an anchor plate 33 within the box 22. A plurality of tension springs 34 (only two illustrated) within the box 22 have one end connected to the plate 33 and the other end connected to an anchor plate 35 fast with the interior of the box structure.

A generally vertically-extending rod means 36 is attached at its lower end to the foot of each member 30, the two rods being connected together at the upper ends by a cross-bar 37. A downwardly-extending plate 38 is fixed to the bar 37 and carries a pivot pin 39 which mounts a bedclothes retaining board 40 for pivoting movement thereon. The pin 39 is much closer to one end of the board than the other, so that the board 40 is movable under the effect of gravity from a vertical bedclothes retaining position (when it engages the vertical face of an L-shaped stop member 41) and a horizontal concealed position (when it engages the horizontal face of member 41) in which it is concealed behind a decorative headboard 42. The headboard is fastened to a bracket member 43 which is hinged by hinges 44 to the end member 15. Brackets 45 fastened to the back of the headboard 42 are provided with respective slots which embrace the respective rods 36, so that the movement of the board 42 is controlled by the rods. A flexible connection, comprising a chain 46 provided with a shock absorbing/tensioning spring 47, has one end connected to the rear of the board 42 and the other end connected to the rear of the board 40, the connection being such that downward movement of the headboard 42 will cause clockwise rotation of the board 40 from the concealed to the retaining position.

The operation of the bed is as follows:

With the bed in the position as seen in FIGURE 2, the pivot 29, comprising the centre of action of the counterbalance springs 34, is at its position of maximum horizontal spacing and minimum vertical spacing with respect to the support pivot 24, the springs 34 are at their maximum extension, the chain 31 is taut, the headboard 42 is vertical, the chain 46 is slack, while the retainer board 40 is horizontal and concealed behind the board 42. Although the springs are at their maximum extension, the rotative force which they apply to the bed about the pivot 24 is also determined by the vertical spacing between the two

pivots

24 and 29. The total rotational force is arranged to be not sufiicient to raise the bed by an adequate mar gin, so that there is no tendency for the bed to lift of its own accord, and yet it can readily be lifted when required by an elderly person or a small child.

As the bed rises toward the intermediate position shown in FIGURE 3, as indicated by the arrow 48, there is a rapid. increase in the said vertical spacing betweenthe

pivots

24 and 29, causing a rapid increase in the rotational force applied by the springs; the rotational force is decreased somewhat by the reduction of the spring elongation, but the overall effect is an increase in the force, so that the bed becomes virtually weightless once it has been lifted a few inches off the floor and can be arranged to continue its upward movement virtually of its own accord. At some point in the upward movement the legs 27 rotate to the stored position, as indicated by the arrow 49.

During this movement of the bed frame the headboard 42 is rotated from a position generally perpendicular to the mattress to a position in which it is generally parallel thereto, at which it will engage a pillow (indicated by 50), laid at the head of the bed and hold it in firm engagement with the mattress 17. The headboard has also moved downward, as indicated by the arrow 51, the brackets sliding along the rods 36, thereby initially tightening the chain 46 and thereafter causing the chain to rotate the bedclothes-retaining board 40 about its pivot 39, as indicated by the arrow 52, to the vertical position shown in which it presses on the top surface of the bedding, and holds the bedding and the mattress neatly in place.

As the bed moves further toward the position shown in FIGURE 4, the chain 46 is still taut, being held in that condition by the spring 47, while the chain 31 now becomes slack, so that the springs 34 are no longer attempting to rotate the bed, but instead are effective to press the boards 42 and 40 (particularly the latter) respectively into strong engagement with the pillow and the bedclothes and hold them firmly in place on the mattress. During this final stage of the upward movement thesaid vertical spacing does not change, the springs reach their minimum extension and the rotative force is now at a minimum, while the horizontal spacing is now approximately at a minimum. As seen from FIGURE 4, the bed frame is arranged to tilt backwards a small amount in its final position, so that the bed is now held in this position by gravity and there is no possibility of it swinging downward of its own accord.

As the bed is swung from the vertical storage to the horizontal sleeping position the sequence of events is reversed. The

boards

42 and 40 are held by the counterbalance springs in firm engagement with the pillow and bedclothes until the bed frame has rotated sufliciently for the chain 31 to become taut, and thereafter they are moved under the action of the chain away from such engagement. As the headboard 42 pivots to its vertical position it also moves upward along the rods 36, permitting the board 40 to rotate under the effect of gravity to the horizontal concealed position. The springs have their minimum effect while the bed is moved through its truly vertical position, but rapidly become very effective thereafter until the bed is nearly in its horizontal position, becoming less elfective in the fully horizontal position, so that the bed moves positively to that position.

The embodiment of FIGURE 5 is functionally equivalent to that of FIGURES 1 to 4, but'is of considerably simpler construction. Thus the springs 34 are connected between a member 35 integral with the side member 20 and an anchor plate 33 which is pivotally connected to an L-shaped member 30 at the junction of the two arms thereof. The pivot 29 is located at the free end of one arm of the member 30, while the chain connector 31 is connected thereto adjacent the free end of the other arm.

The other major difference between the two embodiments is that the bedclothes retaining board is not concealed in the operative position of the bed, but is of decorative shape and appearance and remains always in view. In this embodiment the board is pivotally mounted, by means of a pin 39 on an upstanding rod 38 fixed to the cross bar 37, for rocking movement in the directions of the arrows 50, so that the board will accommodate itself to the outline of the bedclothes as it contacts them. The pin 39 is above the centre of gravity of the board so that it will always return automatically to the position illustrated. The parts 36 to 39 comprise a unitary structure that is removably mounted in sockets 51 at the free ends of the arm members 30.

It will now be seen that I have provided a simple, inexpensive but highly effective construction in which a single set of springs not only oppose the weight of the bed with a desired opposition characteristic, but also are arranged at the appropriate attitude of the bed to operate the bedclothes retaining means. Moreover, by mounting the operating mechanism in two simple individual units at each side of the bed I am able to mass produce them as individual operating units that can be applied to beds of different widths and lengths. For example, with a bed and headboard of a specific width all that need to be changed in the base frame is to provide two new

transverse members

11 and 37 of the required width. By the use of multiple springs the force exerted by each spring assembly can readily be adjusted by providing a suitable choice of springs of different strengths and/or by adding or eliminating springs.

It will also be apparent that I have provided a structure which can be disassembled and accommodated for shipping and storage in a compact space. For example, the particular embodiments described herein can accommodate a full size mattress measuring 78" x 54", and yet can be packed for shipping in a carton measuring 63 x 24". It will be understood that particular embodiments only of the invention have been shown and described.
