  • the housing includes separable upper and lower insulating members and an integral handle set into an annular recess for receiving and storing a compressor hose.
  • the housing defines a neat and aesthetically pleasing appearance, and the handle is constructed and disposed for easy handling of the unit.
  • the interconnection between the housing and the compressor sub-assembly is constructed for maximum vibration isolation and sound deadening, and is designed for ease of assembly and cool operation.
  • the present invention is directed to a housing assembly for an air compressor or the like which encloses and efficiently supports an air compressor sub-assembly for quiet and cool operation.
  • the housing assembly serves to help isolate the air compressor subassembly, and, in the case of an electric version, assists in electrical insulation so that the unit is relatively free from vibration and is double insulated.
  • the housing includes an integral handle for ease in carrying, and the latter is set into and surrounded by an annular recess for convenient storage of the compressor hose when the unit is not in use.
  • the described housing presents a neat and esthetically pleasing appearance which is devoid of unsightly fasteners and the like.
  • the assembled unit is small, compact, and is well balanced for easy handling and storage, and is ideally suited for use by home owners as well as in more demanding environments.
  • the main objects, therefore, of the present invention are to provide a novel housing assembly for a portable, air compressor, or the like, including an electric powered, air compressor sub-assembly, wherein the housing construction neatly and efficiently encloses, supports, and electrically insulates and vibrationally isolates the air compressor sub-assembly.
  • Additional objects of the present invention are to provide a novel housing assembly of the above character which affords easy assembly of the air compressor sub-assembly, and which is relatively inexpensive to manufacture, rugged in construction, and reliable in use.
  • FIG. 1 is a perspective view illustrating an air compressor housing assembly embodying the present invention
  • FIG. 2 is an enlarged end view of the structure of FIG. 1;
  • FIG. 3 is a sectional view of FIG. 2, taken along the line 33 thereof;
  • FIG. 4 is an enlarged sectional view of FIG. 1 taken along the line 44 thereof;
  • FIG. 5 is'a sectional view of FIG. 3, taken along the line 55 thereof;
  • FIG. 6 is a partially exploded, sectional view of FIG. 3 taken along the line 66 thereof;

  • FIG. 1 An air compressor housing assembly embodying the present invention is illustrated generally at 11 in FIG. 1 and is seen to include separable upper and lower members 13, 15.
  • an air compressor subassembly 17 is enclosed within the lower housing member and is electrically powered such as, for example, from a conventional AC electric, power source connected thereto through a line cord 19.
  • the air compressor when energized, is constructed to deliver compressed air through a hose 21 which extends upwardly through a fitting 22 disposed in an opening in the upper housing member 13.
  • the hose 2! at its other end, is provided with a suitable fitting 25 for connection to a suitable output device.
  • On/off control for the air compressor is afforded by a switch 26 having ears 28, trapped between lugs 32, 34 integral with the housing members 13, 15, respectively.
  • the switch 26 includes an externally accessible rocker type operator 27 for operation thereof.
  • Suitable resilient feet 29 may be secured to the bottom of the lower housing member 15 to prevent surface marring, to enhance stability of the unit, and isolate vibration from the surface on which
  • the field laminations 33 are supported upon a plurality of ribs 39 formed integral with the bottom housing member 15. At the top, the laminations 33 are engaged by a plurality of spaced, sponge rubber pads 41 carried by ribs 42 integral with the upper housingmember 13 when the latter is in place on the lower housing member 15. As shown, the upper housing member 13 is fixed to the lower housing member 15 by screws 43, 45, 47.
  • An armature-piston (not shown) is slidably disposed within the cylinder housing 31 and is adapted to reciprocate upon energization of the field laminations 33-. When this occurs, air is alternately drawn in through air inlet openings formed in the lower housing member 1 l5 and is discharged through a coupling 37 to which the air hose 21 is connected. Suitable valve means is provided in the cylinder housing 31 to control inlet and discharge of air thereto.
  • Martin O. Schrock, et al. Ser. No. 333,018, filed Feb. 16, 1973, and owned by the as signee hereof. i
  • a rubber, rubberlike, or foam sleeve 49 constructed of, for example, unsaturated propolymer ethylene propylene rubber, is int'erposed between the cylinder housing 31 at the intake valve assembly 51 and the air inlet openings 35.
  • This sleeve 49 defines an expansion muffling chamber 53 which requires that the sound generated by the action of the intake valve 51 pass through this chamber and the small inlet openings 35 to the outside of the housing 11. This action serves to break up and greatly reduce the audibility of the valve noise.
  • sleeve 49 serves to assist in isolating vibration of the compressor cylinder 31 from the lower housing member 15.
  • a removable filter 57 constructed of,
  • polyurethane foam or felt can be disposed within an annular chamber 59 in the outer surface of the lower housing member over the inlet openings 35 to filter the incoming air.
  • the housing members 13, 15, being formed of a relatively high strength, plastic material having good electrical insulating properties, such as, for example, Abson 89, manufactured by B. F. Goodrich, serves to electrically isolate and insulate the user from the electric air compressor sub-assembly 17.
  • the compressor sub-assembly 17 is transversely and longitudinally clamped within the housing 11 by means integral with the upper and lower housing members 13, 15.
  • This means includes tapered walls 58, 60 formed integral with ribs 39, and tapered walls 70, 72 formed integral with ribs 42. The tapered walls 58, 60 and 70, 72 clampingly engage the laminations 33 as shown when the upper and lower housing members 13, 15 are secured together.
  • the pads 41, carried by ribs 42 and located between the tapered walls 70, 72 provide additional and resilient clamping forces on the laminations 33.
  • the compressor subassembly 17 is securely mounted and supported both longitudinally and transversely within the housing 11.
  • a linear fan housing 61 provided with openings (not shown) and having a piston fan 63 therein coupled to the reciprocating armature-piston.
  • This fan 62 draws cooling air inwardly through slots 64 in the housing 11 and circulates it over the air compressor sub-assembly 17.
  • the fan housing 31 is substantially cylindrical in shape and is resiliently supported by means of a band of foam material 63 wrapped therearound and trapped in place between baffles 66, 68 integral with the upper and lower housing member 13, 15. Furthermore, this resilient band of material 63 serves as a seal so that cooling air drawn into the housing 1 1 by the fan 62 and to the left of the resilient band 63, as seen in FIG. 3, is caused to continuously recirculate over those parts of the compressor sub-assembly 17 subject to heating during operation of the unit.
  • the upper housing member 13 is provided with a handle 65 formed integral therewith.
  • the handle 65 is set into a recess 67 in the housing member 13 and which is annular in configuration.
  • the handle 65 protrudes only slightly from the top of the upper housing 13.
  • the annular recess 67 defines an annular storage chamber for the compressor hose 21, and the handle 65 forms somewhat of a winding reel about which the loops of hose 21 may be wrapped, substantially as shown in FIGS. 1 and 3.
  • the handle 65 is disposed with respect to the center of gravity of compressor unit so that the unit is well balanced and easy to handle and transport by the user.
  • the particular construction and inset relation of the handle 65, together with the annular recess 67 provides a highly inexpensive, and yet neat and aesthetically pleasing appearance.
