A door includes a rectangular panel having a first face, a second face, and two pairs of opposing edges, in which the edges of each pair of edges are parallel and in which a first pair of edges is longer than a second pair of edges. The rectangular panel includes a layered composite material, in which a first layer of the composite material has a positive Poisson's ratio (PPR) and a second layer of the composite material is disposed in contact with the first layer and that includes a material having a negative Poisson's ratio (NPR). The door includes a hinge including plates joined together by a joint, in which a first one of the plates is attached to a first one of the edges of the first pair of edges and in which a second one of the plates extends beyond the first one of the edges. The door also includes a handle opening defined through a thickness of the rectangular panel.

An appliance includes an outer cabinet having a front aperture for accessing a processing space. A door selectively engages the front aperture in a closed position to enclose the processing space. A hinge includes a cabinet mount attached to the outer cabinet and having a stop that defines an open position of the door. A hinge pin extends through the cabinet mount to define a rotational axis of the hinge. A sheet metal flange is press fit onto the hinge pin and is fixedly attached to the door. The sheet metal flange is wrapped around the hinge pin and is attached to the door via fasteners. The pin includes a protrusion that selectively engages the stop of the cabinet mount in the open position.

A surgical table comprising a base and a patient support supported between opposed ends of the base, each opposed end including a pitch/roll assembly. The base is configured such that the patient support can be rolled and pitched relative to the opposed ends via the pitch/roll assemblies such that the roll axis of each pitch/roll assembly remains coaxial regardless of how the patient support is pitched or rolled relative to the base. The patient support includes an outer frame and an inner frame supported on, and displaceable relative to, the outer frame. The inner frame is further articulating about, and relative to, itself. The outer frame is rigid in that it does not change configurations.

A multi-piece hydroponic tower is provided which utilizes separate tower body and face plate components that are hingeably coupled together, thereby simplifying tower construction as well as tower maintenance. In addition to the hinge, the tower face plate(s) is held in place with a latch, e.g., a snap-fit fastener. A V-shaped groove may be included on either side of the tower, the grooves increasing the efficiency of delivering water and nutrients to the plants via the narrowed rear cavity wall(s). The V-shaped grooves may also be used as an alignment aid when coupling planters, harvesters, or other equipment to the tower.

A door hinge includes a door flange. The door flange includes a first-cylindrical portion. The first-cylindrical portion segmented and having an axially vectored borehole therethrough. The door hinge includes a frame flange. The frame flange including a second-cylindrical portion. The second-cylindrical portion segmented and having a corresponding axially vectored borehole therethrough. The first-cylindrical portion and second-cylindrical portion are configured to engage when their respective boreholes are coaxial. A plurality of apertures are disposed on the door flange and the frame flange. A plurality of plugs are included with the door hinge. Each of the plurality of plugs are sized and dimensioned to close at least one of the plurality of apertures. The door hinge is useful for attaching a door to a door frame.

A compliant hinge for deployable membrane-like structures and other applications is provided. The compliant hinge generally includes a flexible intermediate portion having one or more enclosed contours connected by inner longitudinal segments along a longitudinal axis of symmetry. The enclosed contours are resiliently deformable in response to an in-plane load, including tension and shear forces. The compliant hinge allows for rotation, bending, and extension, and can interconnect rigid panels in tensioned precision structures and other applications.
