  • Publication number: 20200082680
    Abstract: The present disclosure concerns a warning device comprising a warning body having a longitudinal axis and comprising a light-emitting assembly; and a collapsible stand configurable in a compacted configuration and in a warning configuration in which the light-emitting assembly is at least partially visible. The collapsible stand comprises a handle sleeve mounted to and slidable along the warning body and legs pivotably mounted to the handle sleeve, the legs being juxtaposed against the warning body when the collapsible stand is in the compacted configuration to cover the warning body and the legs extending outwardly and downwardly when the collapsible stand is in the warning configuration, the collapsible stand being configurable between the compacted configuration and the warning configuration by sliding the handle sleeve along the warning body. The disclosure also concerns a warning assembly comprising such a warning device and a method of emitting a warning light signal.

  • Publication number: 20200041140
    Abstract: A grease filter (10) has a frame (12) and a grease filter baffle assembly (14) which includes a front (30), a rear panel (32), and an air deflector assembly (34). The front panel has entrance openings (38) therethrough and a series of first bypass holes (42) therethrough. Similarly, the rear panel has a series of exit openings (46) therethrough and a series of fourth bypass holes (50) therethrough. The air deflector assembly has a repeating series of convoluted first baffle walls (56) and a repeating series of convoluted second baffle walls (58). The first baffle walls include second bypass holes (60) therethrough. The second baffle walls includes third bypass holes (62) therethrough. The combination of the front panel, first baffle walls, second baffle walls, and rear panel create a primary air flow channel (66) and a bypass air flow path (68).

  • Publication number: 20200003476
    Abstract: A combination light and pressure relief vent (10) is disclosed which includes a housing (11), a valve assembly (12), and a light assembly (13). The housing include a multi-radial positionable valve body (16), port tube (17), and an outside louver (18). The valve assembly includes a low positive pressure exhaust valve (57), a high positive pressure exhaust valve (59), a low negative pressure intake valve (61), and a high negative pressure intake valve (62). The light assembly includes a heat sink casing (68) which defines a heat chamber (37) and which includes a projection (80) extending into the heat chamber. The casing is coupled to an LED module (57) wherein heat generated by the LED module is transferred through the casing to the heat chamber to warm the valve assembly.

  • Patent number: 8573002
    Abstract: A portable cooler has a thermally isolating outer shell defining an internal compartment for holding contents to be kept cool, such as, for example, food, drinks and temperature-sensitive medicine. The portable cooler has a door connected to the outer shell for providing unrestricted access to the internal compartment. The portable cooler may have a shelf for holding a cold gel pack to help keep the contents cool. The cooler may also have a plurality of dividers (that are optionally reconfigurable) for defining variously sized storage spaces for the contents. The cooler may have an aesthetically pleasing curved outer shell and an adjustable shoulder strap so that the cooler can be carried on a person's shoulder. Because the cooler is easy and comfortable to carry and because its large swing-open door provides full and quick access to its contents, this cooler is more ergonomic and aesthetic than traditional designs.

  • Publication number: 20080149000
    Abstract: An adjustable table has a pair of substantially parallel legs pivotally mounted to a base and extending upwardly to connect pivotally to a table top support to thus enable the table top support to cant between a forward-leaning posture and a rearward-leaning posture. A table top is rotationally mounted to the table top support to enable the table top to rotate relative to the base. The table top can have an upper panel that extends horizontally relative to a lower panel. The table top can also have a tilting mechanism to tilt the upper panel of the table top relative to the lower panel. Telescopic legs can furthermore provide height adjustment. This table can adopt multiple configurations and postures, thus providing an ergonomic, adjustable table for a variety of uses and applications.
