Definitions

  • This invention relates to an adjustable bed for home use which is provided with a powered mechanism for raising and lowering the head and foot portions of the bed springs.
  • Adjustable beds provided with a manual or powered mechanism for raising and lowering the head and foot portions of the bed springs or mattress supports are widely used in hospitals, and although it would be desirable to have beds with these adjustable features in the home, those designed for hospital use are not suitable for this purpose.
  • This difference in height is also important because it permits the mechanisms for raising and lowering the head and foot portions of the hospital beds to be conveniently mounted underneath them. Since the space heneath beds in the home is substantially less than that available under hospital beds, it would be difficult to similarly install the adjusting mechanism beneath them without causing an objectionable increase in height.
  • mattresses used with hospital beds are comparatively light to permit them to be conveniently removed for cleaning purposes. Furthermore, they are made rather inexpensively in anticipation of their rather short useful life so that when they must be destroyed, either for hygenic reasons or when they are worn out, the loss will not be too severe. Since they have an anticipated short life, problems of local strains caused by people sitting on edge of the beds, for example, are not a serious consideration.
  • the mechanism for adjusting the head and foot portions of the hospital beds is freely exposed so that the beds can be readily and frequently hygenically cleaned. This is not suitable for general home use where it is more important to prevent any substantial accumulation of dirt. In addition, it is important to be able to prevent access to the mechanism by any children in the household.
  • adjustable beds such as used in hospitals are not suitable for home use because they cannot fit into the general decor of the home, they are too high, they lack sutlic-ient peripheral support for the mattress, and the mechanism for adjusting the bed is freely exposed.
  • a further object of this invention is to provide an apparatus which can be installed as a unit between the side frames of a conventional bed for converting it to an adjustable bed.
  • Yet another object of this invention is to provide a bed suitable for home use which is provided with means for raising and lowering the head and foot portions of the mattress supports or bed springs, and which provides a large degree of peripheral support for the mattress.
  • Still another object of this invention is to provide a bed suitable for home use which is provided with a housing for protecting the mechanism for raising and lowering the head and foot portions ofthe mattress supports.
  • Yet a further object of this invention is to provide a bed suitable for home use in which the bed frame is also a housing for protectively mounting a mechanism for raising and lowering the head and foot portions of the bed springs or mattress supports.
  • Still a further object of this invention is to provide a ed frame for an adjustable bed which is formed from a plurality of planks assembled together.
  • Yet another object of this invention is to provide an adjustable bed suitable for home use in which the bed frame is formed from a plurality of connected planks mounted on edge and in which the mechanism for raising and lowering the head and foot portions of the mattress supports are mounted intermediate the opposite horizontal edges of the planks.
  • FIGURE 1 is a perspective view of the completed adjustable bed constructed according to the principles of this invention.
  • FIGURE 2 is a sectional view lengthwise along the center of the bed frame showing the adjusting mechanism
  • FIGURE 3 is a sectional View taken on the line 3-3 of FIGURE 2.
  • an adjustable bed indicated generally by the reference numeral it comprises a combined housing and bed frame, indicated by the reference numeral 12.
  • the combined housing and bed frame is rectangular in cross-section, and in this particular embodiment is formed from a plurality of planks horizontally disposed and on edge.
  • planks which form the supporting walls of the combined housing and bed frame are preferably formed from an inexpensive kind of wood, although other materials may be used. The important thing is that the height or width of the planks or supporting walls be large in comparison to their thickness.
  • the planks are assembled with their upper and lower edges 17 and 19 horizontally disposed to form spaced parallel side walls 16 and opposed parallel end walls 18, which are connected to the opposite ends of the side Walls.
  • legs 2% which may consist only of casters, are connected to the planks or supporting walls.
  • the length of the legs projecting below the lower edge 19 of the planks or supporting walls is small in comparison to the width or height of the planks so that the width of the planks substantially determines the height of the bed, exclusive of the mattress.
  • This arrangement helps prevent dirt from entering the combined housing and bed frame from beneath the lower edge 19 of the supporting walls.
  • it helps keep the height of the adjustable bed equal to the height of the standard conventional beds found in the home.
  • An articulated bed spring indicated by the reference numeral 22, see FIGURE 1, is secured to the combined housing and bed frame.
  • the bed spring comprises a peripheral frame 24 and a resilient spring system 26 connected therebetween.
  • the peripheral bed spring frame 24 is rectangular in shape to conform to the peripheral shape of the combined housing and bed frame, and in this particular embodiment it comprises a central portion 28 and end portions 30 and 32, which are pivotally connected to the central portion 28 on pivots 34 and 36, see FIGURE 2.
  • end portion 32 is itself articulated at pivot 38. It is understood, however, that the principles of this invention are applicable to bed springs which are articulated in any manner.
  • horizontally extending support bars which in this case are angle irons 4t
  • angle irons 4t are horizontally disposed and rigidly secured to the inner side of the supporting walls 16 of the combined housing and bed frame, and these angle irons are substantially centrally positioned between the opposed horizontal side edges of the supporting walls for reasons to become apparent below.
  • a powered mechanism is also supported by the angle irons 40.
  • This mechanism includes a pair of hydraulic cylinders 46 in which the pistons 48 are slidably mounted in a manner well known in the art. As seen in FIG- URE 2, these cylinders are mounted on support plates 43 which are rigidly secured to and depend from the angle iron support bars 40.
  • Each of these pistons is connected to a lever system and these lever systems are connected to the end portions 30 and 32 of the bed spring frame 24 to cause them to pivot with respect to the central portion 28 whenever the powered mechanism is actuated.
  • the lever systems comprise bell crank levers t) and 52, pivotally connected on the support bars 40, and respectively associated lever arms 51 and 53. It is apparent that operation of the pistons 46 transmits movement to the lever arms 51 and 53 through the levers 50 and 52. This will impart the desired adjustment of the end portions 30 and 32, since the lever arms 51 and 53 are pivotally connected to the end portions at 55 and 57, respectively.
  • both the articulated bed spring and the mechanism for pivoting the end portions of the bed spring are mounted on the angle iron support bars 4%.
  • the im portance of this arrangement is that both the bed spring and the powered mechanism can be conveniently mounted as a unit between the side frames of any conventional bed. This arrangement is very useful because it permits conventional beds to be modified so they have been adjustable features without disturbing the harmony of the bedroom suite or the decor of the home.
  • the combined housing and bed frame 12 is formed from a plurality of planks. As seen in FIG- URE 3, the ends of the planks may be conveniently and economically connected together by means of the wooden corner sections 13, which in this embodiment happen to be arcuate for decorative purposes.
  • the combined housing and bed frame is formed from planks which may be made of a very inexpensive untreated wood, the planks, or at least their external surface and top edge, may be encased in a soft resilient upholstering material both for decorative purposes and for protecting the planks to some extent from the effects of humidity.
  • the principal portion of mattress 54 rests on bed springs 22, part of the lower surface 56 of its peripheral portion 58 rests on the top edge 17 of the planks forming the supporting walls of the combined housing and bed frame.
  • the peripheral bed spring frame 24 is positioned so it lies within the periphery of the combined housing and bed frame and is positioned closely adjacent to the supporting walls.
  • the bed spring frame is further positioned so the upper edges 29 of this frame are in substantial correspondence with the upper edge 17 of the walls of the housing when the bed spring is entirely horizontal, and when the bed spring frame is also encased in a soft resilient upholstering material for protection against humidity and to reduce wear on the lower surface of the mattress, it is almost flush with the upper edge 17 of the supporting walls.
  • This is an important feature because it increases the amount of support for the peripheral portion 58 of the mattress. This increased support is needed when the bed springs and mattress are entirely horizontal because the greatest peripheral strains occur then, due to people sitting on the edge of the bed.
  • a floor 21 could be secured to the lower edge 19 of the combined housing and bed frame to completely seal the housing and protect the spring system and the powered mechanism mounted inside.
  • An adjustable bed comprising a combined housing and bed frame, said combined housing and bed frame comprising at least supporting walls connected together,
  • said supporting walls having opposed upper and lower horizontal edges, the height of said Walls large in comparison to their thickness, at least the external surface and upper edge of said walls protectively encased in a soft resilient upholstering material, legs connected to said supporting walls to support the combined housing and bed frame, the length of said legs projecting below the lower edge of said walls small in comparison to the height of said walls, an articulated bed spring, said bed spring comprising a peripheral frame and a resilient spring system connected therebetween, said peripheral frame similar in shape to the peripheral shape of said combined housing and bed frame and comprising a central portion rigid with the peripheral frame and pivotally connected end portions all protectively encased in a soft resilient material, the central portion of the peripheral frame of said bed spring horizontally disposed and rigidly mounted between the opposed Walls of the combined housing and bed frame, and a mechanism protectively mounted in said housing and connected to the end portions of the bed spring to cause them to pivot with respect to the central portion of the bed spring, said mechanism comprising a bell crank lever pivoted intermediate its ends to the combined housing and bed frame
