  • Patent number: 4752977
    Abstract: A crib having a frame and a bed supported by the frame includes at least one side rail assembly for enclosing one side of the bed surface. The side rail is attached to the frame for raising and lowering movement of the side rail. A latch assembly releasably secures the side rail in a raised position. A handle assembly includes a first rod connected to the side rail. A second rod is slidably connected to and located above the first rod for movement relative thereto. An actuator is connected between the second rod and the latch so that movement of the second rod toward the first releases the latch. The rods may be pivotally moved away from the side rail. A projection attached to the side rail is positioned between the rods to prevent movement of the rods for releasing the latch unless the rods are first pivoted away from the side rail.

  • Patent number: 4726087
    Abstract: A foam pillow has two main support surfaces on opposing sides thereof. One surface includes convolutions defining a relatively flat profile and the other surface includes longitudinal ribs of arcuate cross-section, which define a curved profile having at least two prominent lobes of differing heights and a central trough. The pillow is particularly adapted for support of a person's head in the trough, with the user's neck received on one of the lobes. Reversal of the lobes permits variation in the amount of neck support. The ribs comprise spherical ridges and have circular channels separating their bases to provide a heat and moisture dissipation function. The curved support surface may include cross-hatching at various intervals to provide extra dispersion of pressure.

  • Patent number: 4715246
    Abstract: A three-speed planetary transmission which mounts inside the wheel hub concentric with the pedal drive shaft on the axis of the driving wheel of a vehicle such as a tricycle taxi. The transmission is characterized by three planet gears mounted in bearings on a gear carrier fitting driven by the pedal drive shaft. Rotatable sun and ring gears, which can be selectively locked against rotation, are in constant mesh with the planet gears. Conventional free-wheel ratchet mechanisms transfer torque from the sun and ring gears to the wheel hub. Two low gear ratios are provided to facilitate initial movement of a heavily loaded vehicle. The simplified gear shift, low maintenance, and compact nature of this chainless three speed transmission provide an improved alternative to the conventional three-speed chain drive for heavily loaded tricycles.

  • Patent number: 4713851
    Abstract: A suspension system for a bed or bunk which is to rest on a substantially horizontally oriented deck and is particularly adapted for the sleeper compartments of large truck cabs and which substantially reduce the amplitude of vibrations and other disruptive movements of the truck. The system includes a lower support frame which is adapted to be on the deck. An upper support frame for supporting a mattress is positioned above the lower support frame. The two frames are interconnected by at least two torsion spring members wherein the upper support frame is free to move up and down relative to the lower support frame under the influence of the spring action of the torsion spring members. The spring action dampens the transmission of up and down movements from the truck to the upper support frame and the mattress positioned thereon.

  • Patent number: 4704749
    Abstract: A body lift (10) has a wheeled frame (12) and drive motor (42, 44) for moving the frame (12) on its wheels (48, 54). A vertical support (14) extends upward from a base (32) of the wheeled frame (12). Arm and leg support pairs (56, 58 and 78, 80) are movably mounted for translation along the vertical support (14). An elevation motor (28) is connected to lead screw (16) to move the arm and leg support pairs (56, 58 and 78, 80) along the vertical support (14). The leg supports (78, 80) of the leg support pair are laterally pivotable toward and away from each other. A torsion spring (102) is connected to urge the leg supports (78, 80) to a normally outwardly pivoted position. The arm supports (56, 58) of the arm support pair are coupled to pivot the leg supports (78, 80) inward laterally in response to weight applied by a user to the arm supports (56, 58).

  • Patent number: 4704751
    Abstract: A device for securing slats to the frame of a bedspring comprised of a support partially encircling the end section of the slat and continuing in two straight sections longitudinal thereto, which constitute joining means to the frame since they are introduced in the holes of the inner wall thereof. The straight sections of the support are secured in a ferrule of the slat, in the bottom of which there has previously been placed damper means which absorbs the pressure of the slat. The slats constituting the support base for the mattress can have different widths, depending on the weight to be supported, according to their location, thereby reinforcing the corresponding zones.

  • Patent number: 4691393
    Abstract: A bed-like stretcher for supporting a patient includes a bed surface frame pivotally connected to a base. A gas spring fixes the frame in position relative to the base. A hand-operated actuator mounted to the frame is moveable in first and second opposite directions, and is biased into a normal position. A rod connects the actuator to a release rod for the gas spring, whereby movement of the actuator in either direction releases the spring to permit pivotal movement of the frame. A stop bar is secured to the frame to be adjacent an upward-facing stop surface on the base when the frame is horizontal. The bar is biased into contact with the stop surface when the frame is horizontal to prevent downward pivotal movement of the foot end. A cable connects the stop bar to the actuator, whereby movement of the actuator in one direction causes the cable to slacken and movement of the actuator in an opposite direction causes the actuator to pull the cable to withdraw the bar from contact with the stop surface.

  • Patent number: 4691952
    Abstract: A mechanism for reliably adjusting and securing the load applied through a keeper and a tension latch assembly is provided. The mechanism includes a housing (25, 35), a drive system (50, 70) for effecting the adjustment, and a clutching arrangement (50, 60, 70, 80) within the housing which prevents the drive system from effecting any further adjustment when a pre-determined load is achieved between the keeper and the hook of the latch assembly. Other features include the placement of the driving component, accessed by the operator, at a location external to the housing and provision of audible and physical indicators for the benefit of the operator when the desired load adjustment has been accomplished.
