  • Patent number: 4305167
    Abstract: A bed making device with a structural support base adapted to receive springs and mattress with two horizontal guide members attached at either end of the base on each side. A carrier arm is slideably positioned on each pair of guide members and contains a retractable detent pin at the top. The pin attaches to a mating opening in the bed linens and the linens are attached to the pins at the foot of the bed. A reversible electric motor with a two position foot switch, limit switch and gear driven belt drive is attached to the arms electromechanically, thereby transmitting linear direction to the mechanism. The carrier arms are horizontally propelled simultaneously forward pulling the bed linens in place. When the linens are so positioned the detent pin is retracted and the arms continue forward to a position near the head of the bed where they stop automatically.

  • Patent number: 4304018
    Abstract: A bed covering includes a top covering adapted to overlie the top surface of a mattress, a side covering adapted to be fitted to the mattress and to surround the head end, foot end and sides thereof, and a foldable side panel interconnecting the top covering and side covering along the foot end and at least one side of the mattress so that the mattress, side panel and top covering define somewhat of a sleeping bag type enclosure for receiving a person. A first zipper along the edge of the top covering and top edge of the side covering enable the bed to be made by simply closing the first zipper to thereby foldably collapse and enclose the side panel between the top covering and mattress. A second zipper may be provided between the side panel and side covering to facilitate entry onto the mattress below the bed covering.

  • Patent number: 4303162
    Abstract: A spring-driven track unit for merchandising soft drink bottles has a sliding sheet metal pusher having a forwardly extending foot and a sloping back extending upwardly and forwardly from the rear edge of the foot. A self-coiling polyester sheet extends from a coil retained at the front of the track, along the supporting surface of the track and underneath the pusher foot. The self-coiling sheet is secured to the back of the pusher and provides a bearing surface for a driving spring which is in the form of a narrow, self-coiling strip. The driving spring is secured to the track near the front end and extends rearwardly in a recess to a coil located behind the sloping back of the pusher. The force of the pusher on the bottles is adjustable by bending the sloping back upwardly or downwardly. The pusher is prevented from sliding off the track by tabs bent downwardly from inwardly extending flanges below and integral with the track.

  • Patent number: 4301559
    Abstract: A sofa bed mechanism consisting of three sections, namely, a rear section, an intermediate section, and a front section, that are foldable between collapsed sofa positions in which the sections are in substantially horizontal vertically stacked positions and bed positions in which the sections extend in substantially horizontal alignment. A frame supports the sections, the frame being of minimum width by which is meant the frame is of a shallow dimension in a direction front to rear of the sofa. The sections are stacked on top of the frame in their sofa positions so that the frame and the sections present a compact substantially rectangular profile when viewed from the end of the frame, thereby allowing substantial flexibility in the design of the sofa in which the mechanism is mounted. The end sections are connected by hinge assemblies located entirely on the sides of the assemblies to avoid the necessity for any cross tubes that might interfere with sleeper comfort in the bed position of the mechanism.

  • Patent number: 4301560
    Abstract: An improved adjustable waterbed mattress with hydrostatic wave absorption comprising a water-inflatable bag-like enclosure containing therein a non-woven or very loosely woven expanded fiber product, unbonded or fixed with a binder to the same or another fiber product, which resists decomposition in water. When a user sits or lies on a conventional waterbed there is a tendency to sink or bottom out especially on the edge and an undesirable wave front is created in the waterbed mattress. The provision of the subject expanded fiber product in the waterbed mattress of the present invention substantially mitigates and dissipates this wave front and allows the bed to be easily packaged, filled, heated, drained and stored.

  • Patent number: 4300269
    Abstract: A device for locking one or more cords or other flexible elements against longitudinal movement, and including two members interconnected for relative pivotal movement between locking and released positions, with one of the members having a portion which is slightly laterally deflectible upon assembly of the device to permit movement of a pivot lug into a pivot recess to form the pivotal connection between the members, and with the other member having an interlocking projection which in the locking relative position of the members blocks lateral movement of the deflectible portion of the first member to prevent disassembly of the parts in that locking position.

  • Patent number: 4300270
    Abstract: The housing for the screw of a hose clip has a tubular section with a flat bottom wall a portion of which extends laterally beyond the tubular section and is overlapped by a plate-like second portion forming part of and being inclined with reference to a side wall of the tubular section. When the screw is rotated in a direction to tension the band which is placed around a hose, pipe or a like structure, the screw tends to move the extension toward such structure. The extension is or can be hollow to receive parts of the overlapping end portions of the band. Reinforcing ribs are provided at the outside of the housing between the side wall of the tubular section and the extension. The housing is made of a sheet metal blank which is deformed to form the tubular section and the two portions of the extension, and such portions of the extension are thereupon welded to each other.

  • Patent number: 4300690
    Abstract: A security display rack comprising an elongated support member appropriately elevated above a supporting surface and an elongated locking member. The support member has an elongated surface and a plurality of grooves extending through the support member and opening at the elongated surface. Each of these grooves is adapted to have at least a portion of an article inserted therein with the grooves spacing the articles along the support member. The locking member is mounted for movement so that it can open and at least partially close the open ends of the grooves. The locking member has a closed position in which it lies along the elongated surface of the support member and at least partially closes the open ends of the grooves. In the closed position, the articles inserted into the grooves either cannot be withdrawn from the support member of their withdrawal is impeded. The locking member can be locked in the closed position.
