Abstract: An improved sleeper bed for over-the-road trucks comprises a first upper frame and a second lower frame with an air spring mounted between the first and second frames for dampening the movement of the frames toward one another. A pair of scissors-like struts extend between the upper and lower frames and allow the upper frame to move up and down according to the amount of force thereon. A pair of pillow block bearings are mounted to braces on the lower frame. A pair of guide rods extend downwardly from the upper frame and are telescopically received in respective pillow block bearings. The pillow block bearings allow the guide rods to shift or pivot slightly when horizontal forces are experienced by the sleeper bed so as to reduce the shock felt by a user thereon.

Abstract: A system for illuminating the interior of a mailbox having a bottom wall, a side and arcuate top wall, a closed rear wall, an open front, and a door pivotally attached to the bottom wall for selectively closing the open front. The lighting system includes a light source positioned within the interior of the mailbox. The lighting system further includes a battery power source mounted within the mailbox. A light sensor is positioned within the mailbox for sensing the level of ambient light within the interior thereof. The lighting system includes an electromagnetic sensor that permits current from the power source to be transmitted to the light sensor upon an opening of the mailbox door. If the level of ambient light sensed by the light sensor is below a predetermined level, the light source is energized to illuminate the interior of the mailbox. Current to the light sensor and light source is interrupted upon a closing of the mailbox door.

Abstract: A modular shelf system having a plurality of shelf modules of various sizes for constructing a modular system for storing or displaying variously sized items. Each module includes opposed walls with an open front side. One wall presents a male attachment structure while the opposed wall defines a female receptacle configured to receive the male attachment structure. The system includes a pair of finish panels for attractively covering the attachment structures of the modules. One panel includes a first generally smooth side and a second side that defines a female receptacle such that the panel can be detachably coupled with a male attachment structure of a shelf module. The second panel presents a first smooth side and a second side having a male attachment structure suitable for detachably coupling with a female receptacle of a shelf module. The lower wall of each shelf module presents connectors which can be detachably coupled with apertures in each upper shelf module wall.

Abstract: A clamshell screw anchor is provided which is inexpensive to manufacture, installable in many types of soils including rocky and frozen soils, and is adaptable for use in various applications, such as supporting electric transmission poles. The screw anchor broadly includes a unitary body member, a core, and a helical load bearing element. The body member is stamped from a substantially flat piece of material, and presents a pair of opposed, elongated body segments depending from a line of symmetry. Each of the body segments includes a first end shaped to define a hub element having a C-shaped cross section, a second end shaped to define a lead point element, and a pair of longitudinally extending side edges. The body member is folded about the line of symmetry, and the body segments are secured together along the side edges so that the hub elements form a hub having an open, upper end, and a rectangular cross-sectional shape, and the lead point elements form a lead point having an earth-engaging tip.
