  • Publication number: 20140352056
    Abstract: A convertible seating unit is adaptable for use in different applications (e.g., motor home, travel trailer, hospital room, commercial, and residential). A frame and linking mechanism reduces the number of steps required to position the unit between seat and bed configurations. The mechanism includes seat and mid seat sections that are attached via a set of articulating linkage which provide that when the seat front is lifted and pulled up/outward, support feet automatically extend without secondary motion by the user. Once the support feet are supported by the floor, a back section is rotated forward from its seat to its bed position, thus completing conversion from a chair to a bed.

  • Patent number: 8555431
    Abstract: A linear actuator device for pieces of furniture, e.g. beds, is described which include an adjustable section (2, 3) pivotally embedded in a frame (1). The section (2, 3) is raised and lowered by at least one rod (23, 24) mounted on a pivot shaft (4, 6). The actuator comprises a housing (8) with a bushing (10) receiving the pivot shaft (4, 6), and a spindle (14) driven by a low-voltage DC motor (11). The spindle (14) carries a spindle nut (12) fixed against rotation which in one direction of motion operates an arm (5, 7) mounted on the pivot shaft (4, 6) for adjusting the section within the piece of furniture. By designing the arm (5, 7) such that, when it engages the spindle nut (12), it will rest against an area (17) of the nut's end which faces farthest away from the shaft, an expedient moment curve for pivoting the section is obtained, as a large moment occurs at the beginning and the end of the section's movement just when needed.

  • Patent number: 8468621
    Abstract: A furniture product includes a folding mechanism that folds into a seat frame. The folding mechanism includes a rear section, a middle section, and a front section, with the rear and middle sections being received in a cavity in the back of the seat frame when the product is in a stowed, seating position. Upon receiving a user input, a position motor deploys the folding mechanism into a sleeping position. Upon achieving the sleeping position, an inflation switch is engaged. An air pump disposed in or near the furniture product is activated in response to engagement of the inflation switch. To return the product to a stowed, seating position, a user input causes the air pump to deflate the mattress and the position motor to fold the folding mechanism into the seat frame.

  • Patent number: 8464370
    Abstract: The present invention is directed to a furniture item having user-support frames that are convertible between a seat configuration and a bed configuration. In one embodiment, user-support frames include a head-support frame anchored by a link assembly to a furniture-item base and a back-support frame pivotably coupled to the head-support frame. The link assembly facilitates both pivoting and lateral shifting of the head-support frame relative to the furniture-item base. In the bed configuration, a cam and cam follower are disposed under the user-support frames, such that when the user-support frames laterally shift, the cam contacts the cam follower, thereby upwardly moving a junction at which user-support frames are hinged to one another.

  • Patent number: 8365322
    Abstract: The patient room window seat converts between a bench seat and a bed with a simple pull of a handle. In the seat position part of a horizontal upholster cushion is under the backrest so the portion of the cushion in available is the correct width for comfortable seating. Moving the upholstered cushion forward until fully uncovered provides a comfortable bed. A second knob removes a stop allowing the cushion to fully extend and leave the base uncovered in a service position that gives full access for cleaning. The patient room seat is constructed with a commercially available heavy-duty ball bearing slides and a modular multi-position remote latching mechanism. The slides and the latching mechanism working in combination provide an effortless transition between the seat and bed position, allowing elderly or weakened individuals to operate the window seat without problem.

  • Patent number: 5336216
    Abstract: An apparatus for delivering a defocused laser beam to a sharp-edged spot (having variable size) in a target plane. The beam has a low power density in a plane of interest between the delivery apparatus and the target plane. In a preferred embodiment, the target plane is the retina of a patient's eye, and the defocused beam profile is controlled so that the beam has low power density at the eye's cornea. The beam produced by the invention is useful not only for ophthalmic surgery, but also for industrial laser heat treating and cutting applications in which a sharp-edged beam cross-section is needed at a target, particularly where delivery of low beam power densities at non-target structures are desirable. In a preferred embodiment of the inventive apparatus, an input laser beam emerges from an optical fiber, and a first lens (having short focal length) is mounted adjacent the optical fiber's output end to receive and transform the input beam.
