Presented is a retractable substantially full passenger cab height cover for vehicle rear portions that renders the vehicle's rear portion open to transport cargo when the full cab height cover is retracted and covered at a full, or nearly so, passenger cab height when the full cab height cover is extended. It has application to all manner of vehicles such as pickup trucks or sport utility vehicles (SUV's) and may be designed in and sold as original factory equipment or sold as an aftermarket product. It is possible, by use of a fold down first tailgate disposed between the passenger cab and the rear portion of the vehicle and fold down rear passenger seat elements to have a very lengthy distance, from a second tailgate at the rear of the vehicle to just behind the driver's seat, for extra passenger seating, storage of cargo, carrying of small boats, or the like. A further refinement includes a multi-system sealing system disposed between elements of the retractable cargo bed cover.

A Collapsible Bed Cap for Trucks is disclosed. The cover has a plurality of collapsible or sectioned ribs extending longitudinally along the length of the bed in order to provide structural rigidity to the cover. The cap or cover is sectional and detachable such that it can be disassembled and/or collapsed and then stored in a single bag. When assembled, the cover has a tight, aerodynamic and aesthetically pleasing material cover to protect truck bed contents from environmental effects. The bed cover further has front and rear arches for strength; these arches are also collapsible for storage. Still further, the cover may be removed from a bed while assembled so that it might be converted into a free-standing awning.

The invention discloses a flooding damage control method for water-diversion fracture main channels of drill-hole-grouting plugged overburden rock. The method comprises the steps: collecting surface-drilling columnar data of all coal mining areas according to development characteristics of altitude of water-diversion fractured zones of overburden rock mined under specific mining conditions, determining stratum positions of all key strata in the overburden rock by adopting a key stratum position distinguishing method, then, determining development altitude of a water-diversion fractured zone of each area and areas of distribution of communicating strata and water-bearing strata of each area by an overburden rock water-diversion fractured zone altitude prediction method, finally, laying out the range of distribution of the water-diversion fracture main channels in areas of the communicating water-bearing strata of the water-diversion fractured zones. and determining a grouting drilling type and drilling construction parameters according to borehole tunnel positions, coal bed cover depth and ground drill distribution conditions; after drilling construction is completed, pumping slurry to areas of the water-diversion fracture main channels so as to plug water-diversion fracture channels. The flooding damage control method for the water-diversion fracture main channels of the drill-hole-grouting plugged overburden rock, disclosed by the invention, is determined, can adapt to different mining conditions and can provide a guarantee for water resource protection, flooding damage control and the like of coal mining of mining areas, the use method is reliable, and the practicability is high.

A disposable cover for a pet bed or resting surface comprises an outer layer having a perimeter; an elastic member located about the perimeter for fixing the cover with respect to the pet bed/resting surface; an inner layer for contact with the resting surface; and an intermediate layer which includes odor-absorbent material. A method of eliminating pet odor comprises providing a resting surface for a pet; covering the resting surface with a disposable odor-absorbent cover; and fixing the disposable cover to the resting surface with the attachment member.

A bed ventilator for drawing surrounding air thereinto, treating the surrounded air drawn thereinto with a selected air treatment component so as to produce treated air and blowing the treated air under a bed covering of a bed, the bed including a mattress and a mattress support supporting the mattress. The bed ventilator includes: a casing including an inlet, an outlet and a passageway extending therebetween for fluidly coupling the inlet and the outlet, the casing being configured and sized so that the outlet is positionable under the bed covering; an air circulator located between the inlet and the outlet for drawing the surrounding air through the inlet and blowing the treated air outwardly from the outlet; and a treatment component support mechanically coupled to the casing for removably supporting the air treatment component within said casing.

A retractable truck bed cover having an array of parallel aluminum slats joined together by connective hinges including leading and trailing edge configuration for improving the security of the cover by covering and concealing the seam between adjacent slats while improving the connective hinge's resistance to the effects of aging and/or exposure to temperature fluctuations. The truck bed cover connective hinge slat is designed to be in an array of discrete slats, which are joined to one another by means of joiner members secured at each end to slat end caps. The distal ends of the joiner members are attached to slat end caps at the distal ends of the slats, thereby preventing the joiner members from shrinking in relationship to the slats due to aging and/or exposure to temperature fluctuations.

Provided herein is a portable device useful for providing ventilation to a selected area via circulation of ambient air. A device according to the present invention is especially well-suited to providing ventilating air to a person resting on a bed, by directing air from the room to the volume defined by the top surface of the mattress of the bed and a bed covering disposed thereon. Use of the present invention increases the ability of persons to achieve restful sleep by enabling convenient control of the air surrounding the person to a comfortable level.
