Underpans Patents (Class 180/69.1)
  • Patent number: 6378639
    Abstract: An oil drip pan assembly for a vehicle for preventing oil from dripping onto the ground from a vehicle. The oil drip pan assembly for a vehicle includes a bracket member being adapted to securely attached to an undercarriage of a vehicle; and also includes a receptacle being removably fastened to the bracket member; and further includes an oil absorbent member being removably supported upon the receptacle for absorbing oil being dripped about an oil pan or from gaskets in the engine; and also includes a screen member being securely and removably disposed upon the receptacle to securely retain the oil absorbent member upon the receptacle.

  • Patent number: 6290013
    Abstract: A battery tray for a motor vehicle which substantially reduces the accidental spill of acid to other parts of the motor vehicle is disclosed. The battery tray includes a planar surface, a front wall, a back wall, and first and second side walls. A first drain trough is disposed on the center of the floor, and a second drain trough is connected to the first drain trough through a drain passage. A third drain trough is offset at an angle from the second trough. The battery tray also includes a drain hole disposed on the third trough and a removable hose attached to the drain hole. The pitch of the troughs are angled in such a way to prevent any acid spill from contacting other parts of the motor vehicle and to direct the flow of the acid towards the drain hole and away from motor vehicle parts.

  • Patent number: 6258430
    Abstract: A portable parking mat and berm of modular construction which allows easy assembly and assures secure retention of liquids dripping from the undersurface of a vehicle. The four edges of a flexible rectangular sheet are individually supported a desired minimum distance above the surface of a garage floor through the use of modular structures installed in end-to-end alignment. One-piece integral side structures are quickly located in alignment along the lateral edges of the sheet and installed through the employment of interengaging parts that secure the flexible sheeting therebetween. Similar structures may be used at the head end, while at the entrance end two-piece modular structures are provided that provide sloping front and rear ramp surfaces designed to support the weight of a vehicle passing thereover while resisting any shifting movement upon their engagement by the tires of the vehicle.

  • Patent number: 6216811
    Abstract: A battery tray that includes a system for controlling the flow of fluid is provided. The battery tray includes a base surface having a retention cup formed therein. The retention cup collects aqueous sulfuric acid discharged from the battery. The retention cup includes a vent or slot formed therein to allow its contents to evaporate over time. A system of troughs and channels are included in the base surface to direct fluid flow towards the retention cup. The battery tray effectively controls the flow of aqueous sulfuric acid so that the acid does not contact neighboring vehicular components. If aqueous sulfuric acid contacts metal vehicle components it will promote corrosion of the components.

  • Patent number: 6202778
    Abstract: A motor vehicle having a sump guard and an undertray assembly attached to the undercarriage of the motor vehicle for protection of the undercarriage and engine. The undertray is made from a resilient plastics material and is moveably connected to part of the body structure of the motor vehicle and is allowed to deflect upwardly when impacted from below by an obstacle. Because of resilient nature of the undertray assembly, the undertray assembly disperses an impact load when applied thereto.

  • Patent number: 6170586
    Abstract: An apparatus for a flexible, attachable and absorbent pad for absorbing fluid leaks from an irregular surface on a motor vehicle. The pad includes an absorbent quilted pad which faces to receive the liquids or oils which drop from an engine part or structure. The pad is made from a heat resistant material which is absorbent enough to absorb a cup or two of fluid. An outer sheet is bonded to the bottom side of the absorbent pad so which is water resistant and able to retain accumulated oil or fluids which may pass through the absorbent pad. Each edge of the outer sheet is folded around the peripheral of the pad and heat sealed or glued to the pad. Tethers, such as wires, cords, or the like, are then disposed through the folded border sections and glued or sealed to the outer sheet and absorbent pad. The tethers are then used to fasten the pad to a fluid leak by connecting the tether together around the vehicle structure which is leaking and molding the pad to the irregular surface.
