  • Patent number: 6431315
    Abstract: Two generally triangular segments of metal or plastic are rigidly or pivotably connected at an angle of about 45 degrees. A flexible strap extends through vertical slots formed in each segment. A strap connector, such as a double bar buckle, is positioned between the two segments. The strap extends through the first slot and around a portion of the strap connector, back out the first slot and around the joint between the segments and into the second slot. The strap passes from the second slot, around a portion of the strap connector, back out the second slot and then around the tree. The free ends of the strap are releasably connected. The edges of the segments may have upwardly angled teeth, such that when the tree step is secured against the tree by downward pressure, the upwardly angled teeth restrain the upward return of the tree step in response to the tension in the strap. Installed, strap tension restricts opening of the two segments, while the strap connector restricts collapse of the two segments.

  • Patent number: 6419610
    Abstract: A truncated triangular inclined climbing wall is attached to a wooden play structure, and is tilted at about a forty-eight degree angle against the play structure, and is fastened by a flange to an elevated deck which is accessible through a wood framed inlet. The climbing wall is staked to the ground, and narrows from a wide, ground-engaging, base, to a narrower summit, which is immediately adjacent the framed inlet. The climbing wall is formed with a number of rock-simulative ledges, which progress from the base to the summit. Each molded ledge preferably has a child-graspable hand grip integrally molded in the riser. The top surfaces of the step-like ledges define treads which are inclined from the horizontal to direct the child's foot inward toward the climbing wall rather than away from the wall and off the structure.

  • Patent number: 6416101
    Abstract: A steel frame supports a trailer body which encloses a refrigerator freezer, a gas stove or grill, and storage space for a generator, LP gas tanks, and canopy components. During transport the trailer is covered by two hinged covers, and two side benches are retracted and retained elevated alongside the trailer body. In use, the covers are rotated 180 degrees about hinges to form counters for service of up to eight diners. Each bench has two legs which are slidably received within fittings on the ends of two horizontal extension members which telescope within tubular cross members mounted beneath the trailer body. The legs are elevated and held in place by spring catches. In service, the benches are extracted and lowered, and the covers deployed to define counters. A canopy has side poles which engage the ground, and bracing poles which extend from the trailer body, all being trailer stowable.

  • Patent number: 6415544
    Abstract: A plastic jaw or striker with downwardly facing teeth is pivotally mounted to a plastic base with mating upwardly facing teeth. A plastic trigger hangs from the base, and a coil spring extends between the jaw and the base rearward of the trigger. The spring holds the jaw in the set position, by engaging the rear of the jaw against the rear of the base. The trap is tuned to be not overly sensitive, avoiding springing of the trap by vibrations or insubstantial rodent entry. The spring or tension axis does not go through the trigger, simplifying construction and arrangement of parts. The open position is limited by the jaw engaging the base. The jaw is just over-center when set, such that a small movement towards closure does not trigger it. The trigger requires fairly large movement, facilitated by the raised pivot axis, to trigger the trap.

  • Patent number: 6412145
    Abstract: A semi-truck door latch handle cover has a rear plate which is positioned rearwardly of and connected to a front plate by a curved connector segment. The cover may have a lip extending rearwardly from the front plate along an edge opposite the connector segment. The front plate is thus positionable to overlie the vehicle latch handle with the lip engaged with the latch handle, and the rear plate positioned rearwardly of the vehicle latch handle, the cover being sufficiently resilient as to permit temporary deformation when the cover is attached to the latch handle. The rear plate may have vertically extending wings which contribute to the positioning of the cover with respect to latch flanges. The lip may extend around three sides of the front plate. Alternatively, a cover without a lip may have a resilient clip extending form the rear plate which connects to a latch axle pin.

  • Patent number: 6401727
    Abstract: Multiple plastic trays are covered with pivotable lids. Each tray is divided into distinct compartments into which infant and toddler toothbrushes, teething rings, pacifiers, or other such personal hygiene products may be placed. The lid is punctured by an array of air holes, which allow moisture to escape from the covered tray, while at the same time protecting the tray contents from contamination. The covered trays are received within an open front rack in a vertically spaced arrangement. Air cavities defined between stacked trays permit natural air flow over the trays, and the removal of moisture from the tray contents. A fan may be attached to the rear of the rack to blow air over the lids and to draw the moist air from within the compartments through the lid air holes.

  • Patent number: 6401604
    Abstract: A series of narrow and tall above-ground stainless steel tanks define independent brining cells into which cheese blocks are conveyed by common inlet and outlet flumes. Each cell has a removable conveyor assembly having a looped plastic link belt driven around a frame by an electric motor. Projecting plastic flights on the belt engage infed cheese blocks, and submerge a series of rows of blocks. An infeed flume delivers a stream of cheese blocks to a cell. Once a level below a flight is filled, the conveyor is actuated to submerge that level, and the next level is then filled until the tank is filled. After brining, the conveyor is incremented to discharge the cheeses flight by flight into an outlet flume.

  • Patent number: 6397517
    Abstract: An injection molded plastic body has a lid joined by a living hinge. A rodent passageway extends within the body between two aligned holes. The hinge is perpendicular to the passageway, allowing the lid to be opened when the body is fixed adjacent a building wall. The interior of the body is divided by a raised wall which is broken into two segments by an opening to a blind passageway extending perpendicular to the passageway. Two rodent feeding areas are positioned adjacent the blind passageway. Bait blocks are positioned within each feeding area on protrusions which are received within axially extending central holes. The blocks are clamped between underlying rings and cooperating structure depending downwardly from the lid. Instead of bait, a mechanical trap maybe positioned on two of three protrusions aligned along the blind passageway. The mechanical trap inter-fits with the protrusions to positively position the mechanical trap.

  • Patent number: 6394700
    Abstract: A plastic apron endwall is connected to a drain which extends under a highway. The apron endwall is in the form of an upwardly opening trough having a general wedge shape and incorporates lateral wings which extend outwardly from the sides of the apron end wall into the surrounding soil, so that as installed, the soil overburden prevents the apron end wall from being displaced upwardly by buoyancy forces in the event that the ditch into which the apron end wall drains becomes flooded. The total planar area of the wings is selected so that the overburden, that is the soil which lies above the wings, is sufficient to offset any buoyancy force produced by water saturated the soil in which the apron end wall is embedded.

  • Patent number: 6389738
    Abstract: A pest trap has a cover which engages with a base in two alternative positions. The cover has rodent access openings on opposed side walls which, in a first position, align with openings of similar dimensions in the opposed side walls of the base; and in a second position, when the cover is rotated 180°, align with solid portions of the base side walls to block the rodent access openings. A glue board within the base allows it to be used for trapping rodents and insects, or insects alone. The cover has tabs which pivot in base tab holes, and prongs which engage with base ledges to secure the cover to the base. The cover may have interior board restraint fingers which help to retain the glue board in a flat condition. A rod may support a bait block over a tray in place of the glue board.

  • Patent number: 6390029
    Abstract: A water heater has a cold water inlet bushing which screws into a threaded boss in the side wall of a hot water tank near its bottom. Cold water is injected through a pipe into the inlet bushing. A blind passageway is formed within the inlet bushing which extends radially inwardly from the tank outer wall. An outlet port intersects the blind passageway at 90 degrees, and is positioned tangent to the circular outer wall of the hot water tank at the point the tank is penetrated by the inlet bushing. The inlet bushing creates a jet of water which results in the water within the tank rotating. When turbulent mixing and circulation are created by the inlet water jet, smaller particles of sediment which are placed into suspension can be removed from the hot water tank along with the hot water.
