Definitions

  • FIG. 13 is a schematic diagram of a compressor having secondary handles.
  • the base also includes a recess 10 , which, in a preferred embodiment, is a through-hole in the base.
  • the recess 10 accommodates a flywheel 12 so that the compressor can be mounted in an ultra-low profile manner on the base. That is, a portion of the flywheel 12 may pass through the recess 10 .
  • the air reservoirs 4 are positioned on the base 6 such that there is a space 14 between them. As explained further below, additional components of the air compressor are supported in the space 14 and on the portion of the base between the reservoirs.
  • the wheel assembly 26 includes a wheel 28 that is mounted to a pair of brackets 32 , each of which connects the wheel 28 to the air reservoir 4 .
  • the wheel assembly need not be directly mounted to the air reservoirs.
  • the wheel assembly is attached to the second portion 20 of the air reservoirs 4 , opposite the first portion 18 , such that a user may grasp the handles and transport the air compressor, such that the air compressor rolls on the wheel.
  • the configuration of such an air compressor is known as a “wheelbarrow” style air compressor.
  • the benefits of the present invention may be realized based on the position of bottom-most portions 37 , 39 of the pump 36 a and the motor 38 a with respect to the air reservoirs 4 .
  • the bottom-most portions are the lowest portions of the pump and motor from the ground when measured in their normal operating positions.
  • FIG. 10 which shows a cross-section of a circular air reservoir 4
  • the reservoir may be divided into quadrants: an uppermost quadrant 70 , an upper-mid quadrant 72 , a lower-mid quadrant 74 and a lower-most quadrant 76 .
  • At least one air reservoir is oriented on the base so that it is angled with respect to a central axis 44 that passes through the wheel 26 , with the central axis thus being defined as being generally perpendicular to the rotational axis of the wheel.
  • the reservoir 4 will be positioned at an angle ⁇ , labeled in FIG. 4 as 42 , in a range of about one and one-half through five degrees, although in other embodiments the angle ⁇ may have a lesser or greater value depending on design specifications. Because the air reservoirs are angled, the width of the compressor 2 near the wheel assembly 26 will be less then the width of the remainder of the air compressor in the direction toward the handle assembly 16 , with the width increasing towards handle assembly 16 .
  • the pump assembly 36 and motor assembly 38 are at least partially disposed on the top portion 23 of one of the air reservoirs 4 and are positioned so that the profile P of these air compressor components, when viewing FIG. 4 , is substantially parallel to the longitudinal axis 7 of the air reservoir. Having the profile P substantially parallel to the longitudinal axis of the air reservoir leaves room for a flywheel 12 to be disposed in the space 14 and attached to the base 6 .
  • the space 14 is large enough to accommodate flywheels of a variety of sizes, so that a flywheel of a larger size does not need to be disposed on the reservoir.
  • a larger flywheel will not greatly increase the height of the compressor, so that the disadvantages described above associated with compressors having high profiles may be avoided.
  • the joint and handle may be attached to the bottom portion 8 .
  • the handle 22 may be rotated as shown by the dashed line R so that it stores in a position parallel and adjacent to the reservoir 4 (shown in phantom in FIG. 6 as 22 a ).
  • each handle 22 c may include a plurality of nesting portions 80 that allow telescopic movement by collapsing or nesting within each other, as compared to FIG. 7 a , where the handle 22 b is able to slide in and out of the sleeve 50 .
  • the nesting portions 80 may be partially nested so that less than all of the nesting portions are collapsed or entirely nested. Detents or other commonly known release mechanisms may be incorporated to selectively retain the nesting portions 80 in a nested or partially-nested position.
  • such nested handles may be removable so that they do not project outwardly from the air reservoir as described above.
  • each reservoir 4 may include a skid 60 attached to the bottom portion 8 of the reservoir 4 .
  • the skids 60 facilitate the sliding of the air compressor that under certain circumstances may be useful.
  • the skids may be used when loading the compressor into the back of a vehicle, or other situations where it may not be desirable to use the wheel assembly to transport the compressor.
  • the skids may be used to slide the compressor once they have made point contact with the edge of the back of the vehicle.
  • the secondary handles 62 a , 62 b are arranged relative to the compressor's center of gravity, depicted as CG.
  • the secondary handles 62 a , 62 b may be disposed on the air reservoirs as described in the above embodiments.
  • the first secondary handle 62 a is located at horizontal distance Y 1 from the center of gravity CG and second secondary handle 62 b is located at a distance Y 2 from the center of gravity CG.
  • the compressor shown in FIG. 8 is particularly advantageous when it is used in a compressor having reservoirs with a capacity less than two and one-half gallons each, which capacity allows the compressor to be easily transported and lifted by a single user.
  • the air reservoirs may have a greater capacity.
  • the air reservoirs may have a capacity in a range of four to four and one-half gallons each, although the air reservoirs are not required to be limited to such a capacity.
