Definitions

  • This rod is provided with a pair of adjustment arms engageable with the mattress and with a crank connected to one end of a longitudinally extendable motor whose other end is carried on a rigid support assembly connected by hangers to the frame at locations remote from the hangers on the rod.
  • This support assembly may comprise a simple bar extending back from the rod and connected via a hanger to the end beam of the bed or may comprise another rod parallel to the first-mentioned rod and connected via a rigid bar to the first-mentioned rod. It is also possible to provide this second rod with lifting arms driven by an operating crank so as to raise both ends of the mat tress.
  • the present invention relates to an apparatus for lifting a portion of a mattress. More particularly this invention concerns such an apparatus suitable for raising the ends of a mattress lying on a closed rectangular frame formed of a pair of parallel side beams bridged by a pair of parallel end beams.
  • Another object is the provision of such an apparatus which is relatively inexpensive.
  • Yet another object is to provide such an apparatus which can readily be installed.
  • an apparatus comprising an actuating rod extending generally parallel to one of the pairs of side or end beams of the frame and supported on the other of the pairs by hangers provided at its ends.
  • At least one adjusting arm extending radially from and rotationally secured to the rod is operatively engageable with the portion of the mattress to be raised so that on rotation of the rod about its longitudinal axis that portion is lifted.
  • a crank extending radially from and rotationally secured to the rod is connected to one end of a motor which is extensible in a direction transverse to the rod. The other end of the motor is connected to a rigid support assembly having one end attached to the rod and another end connected to the frame at a location remote from the hangers of the rod. 4
  • Such an apparatus can be set into an existing bed frame and can readily function to raise the end of the mattress.
  • the number of working parts is minimal so that the cost of such a device is low and its service life is long.
  • each of the hangers is generally L-shaped, comprising a rigid plate adapted to overlie the respective beam and another plate extending at right angles thereto and adapted to press against one of the inner faces of the beam.
  • the overlying plate is advantageously screwed or otherwise clamped to side beam of the bed.
  • the support assembly according to this assembly can comprise a single rigid bar extending from the rod to a hanger secured to one of the end beams of the bed, or this bar can extend to a second such rod parallel to the first-mentioned rod and similarly secured via hangers at its ends to the side beams of the bed.
  • this second rod is also rotatable and is provided with lifting arms and an operating crank so that the arrangement may be placed in the middle of a bed with the lifting arms extending in opposite directions so as to be able to lift either of the ends of the bed.
  • To this end means is provided for preventing rotation of one of the rods which entails locking the respective crank relative to the rigid bar of the support assembly.
  • each of the rods is formed of a pair of polygonalsection telescoping parts which are secured together by clamping means such as grub or set screws.
  • clamping means such as grub or set screws.
  • the invention according to the present invention can be produced at relatively low cost so that without considerable expense a person needing the features of a hospital bed can buy a simple apparatus which converts his own bed into an adjustable hospital-type bed.
  • the device can be readily set up to operate with twin size or double beds.
  • FIG. 1 is a perspective view of the apparatus according to this invention.
  • FIG. 2 is a perspective view of a bed equipped with the apparatus of FIG. 1;
  • FIGS. 3, 4, and 5 are further perspective views of three other configurations in accordance with this invention.
  • a bed frame comprises longitudinally extending and parallel side beams 1 whose ends are bridged by parallel and transversely extending end beams 2.
  • a mattress 3 lying on top of this frame 1, 2 has an end region 3a adapted to be pivoted upwardly about an axis 4 of a pivotal U-shaped support member 5.
  • the apparatus comprises a rod 6 extending parallel to the end beams 2 and carrying on eachend a radially extending lifting arm 7 which engages the framework 5.
  • a rod 6 extending parallel to the end beams 2 and carrying on eachend a radially extending lifting arm 7 which engages the framework 5.
  • the rod 6 is provided with a crank 8 and is rotatable in a fork l0 fixed to one end of a bar 9 extending parallel to the side beams 1.
  • a motor 11 has an operating rod 12 which is reciprocal as shown by double-headed arrow 13 in a direction transverse to rod 6.
  • the rod 6 at each end is journaled in one plate 19 of an L-shaped hanger 14 whose other plate 20 is adapted to overlie the respective beam 1, while the plate 19 is adapted to press against the surface.
  • a screw 15 passes through each of the upper plates 20 so as to secure the assembly snugly in place.
  • Another such hanger 16 is provided at the free end of the bar 9 with its vertical plate 21 pressing against the inner face of the end beam 2 and its horizontal plate 22 overlying this end beam 1, another screw 15 being provided to secure it in place.
  • the other end of the motor 11 is provided with a fork 32 pivoted at 18 on a bracket 17 slidable along the bar 9 and securable thereon by a set screw 33.
  • the rod 9 is 3 formed by a pair of telescoping sections 9a and 9b which are secured together by a set screw 34.
  • the rod 6 is formed by three such telescoping sections, and outer section 6a and two inner sections 6b secured again by set screws 34.
  • FIG. 3 The arrangement shown in FIG. 3 is identical to that shown in FIGS. 1 and 2 except that a second rod 9' is provided parallel to the first rod 6 and is provided at each end with a hanger 19 having fingers 20 overlying the side beams 1.
  • a rigid bar 24 extends between the two rods 6 and 9' and a mounting block 23 secured to the rod 9 by a set screw 33 holds the fork 32 of the motor 11.
  • the rod 9 is extensible like the rod 6. This arrangement is particularly useful in beds where the entire end section 3a is not to be lifted but a portion inward of the end section so as to raise the knees of the user.
  • FIG. 4 another arrangement is shown which is adapted to lift end sections 3a and 3b of a mattress.
  • Reference numerals identical to those in FIGS. 1-3 are used for identical structure.
  • the principal difference lies in that the fork 32 on the end of the motor is secured via a crank 26 to the rod 9' which itself carries two lifting arms 5 adapted to raise the end 3b.
  • Clutches 27 are provided at the ends of each of the rods 6 and 9 so as to prevent rotation of the respective rod.
  • the user locks the clutch of rod 6 and operates the motor 11 so that portion 312 of the bed will be raised whereas locking of the clutch 9' and releasing the other clutch will cause the motor 11 to raise the head 3a of the bed.
  • FIG. 5 In thearrangement according to FIG. 5 similar reference numerals areagain used for identical structure.
  • a second bar 30 extending between the rods 6 and 9 and a second motor 29 is pivoted at one end on the rod 6 and at the other end on a crank 28 carried on the rod 9. ln this manner the two ends of the mattress can be lifted independently or jointly.
  • the rods 6 and 9' are telescoping as described with reference to FIGS. 1 and 2 so as to permit the apparatus to be adjusted for any width bed.
  • a mattress-displacing unit engageable with said displaceable portion of said mattress for selectively raising and lowering same, said unit comprismg:
  • first hanger means engaging said shaft at opposite ends thereof and mounting said shaft on said longitudinal sides for rotation of said shaft;
  • a stationary rigid bar rotatably engaging said shaft at one end of said bar and extending perpendicular to said shaft for retaining said shaft at a fixed location relative to the other end of said bar;
  • At least one lifting arm extending radially from said shaft and rotatably entrained therewith, said arm having a free end bearing on the undersides of said displaceable portion of said mattress for raising and lowering same relative to said frame upon rotation of said shaft;
  • crank lever carried by said shaft and rotatably entraining same
  • each of said hanger means comprises an L-shaped bracket having a flange adapted to overlie a respective side of said frame and a shank lying within said frame along an inner face of the respective side.
