The configuration of the basket 205 is constructed in relation to the dimensional configuration of the frame 102 and/or handle 110 with which the basket may be connected. In
The maintenance of the structural lines established by the first and second vertical supports may be accomplished through a basket depth dimension which does not substantially protrude from the vertical plane. In effect, the basket 205 provides a sufficient depth for the carrying of accessories, but does not interfere with a perceived verticality of the frame 102 provided by the first and second vertical supports. For example, the basket 205 may be constructed to provide a depth wherein the depth of the basket 205 maintains the visually perceived verticality of the frame 102. In a preferred embodiment, the depth of the basket 205 may range from three to six inches, such depth being visually perceived as not substantially protruding from and thereby interfering with the verticality of the frame 102. It is contemplated that the depth of the basket 205 may vary, providing greater depth than six inches or less depth than three inches without departing from the scope and spirit of the present invention while maintaining the perceived verticality of the frame 102 at the location of the first and second vertical supports 113 and 115.
The configuration of the basket 205 may vary to accommodate the shape of the air compressor to which it is connected. The various configurations may allow the basket to have contouring, different polygonal designs, and the like which provide an aesthetically pleasing appearance and maintain the overall shape of the air compressor 100, including the frame 102.
In the current embodiment, the basket 205 is configured in a generally rectangular box shape which extends between and connects with the first and second vertical supports, extends at least partially down the length of a section of the frame 102, and has a depth. It is understood that the length of the basket 205 may vary significantly. This variance allows the basket 205 to be constructed in accordance with the needs of a consumer or manufacturer. Further, the various lengths which may be constructed for the basket 205 allows it to vary in how far the basket 205 extends down the frame 102. The width of the basket 205 may also vary significantly. This variance in the width of the basket 205 provides different basket constructions which protrude out from the frame 102 at various distances without departing from the scope and spirit of the present invention.
The basket 205 of the accessory carrying assembly is enabled to carry various items, such as attachments for the hose, nails, nail guns, hammers, wrenches, and the like which may be utilized with the air compressor 100. Further, as may be seen in
In an alternative embodiment, the basket 205 may be configured as an enclosure with continuous surfaces joined together to form a closed container. This may be advantageous in its ability to store and carry items which may fall out of the wire form of the basket 205. The closed basket may be formed of varying dimensions such as those described above for the wire form basket. Further, the basket may be configured to include various devices, such as a connector assembly, and the like for increasing the utility and ease of use of the basket.
It is contemplated that the basket 205 and hanger of the accessory carrying assembly may be alternately used with other power devices as well. For example, they may be employed with a generator, portable generator, power washer, other hydraulic pump assemblies, and the like. When used with various alternative devices, the accessory carrying assembly may include additional features than the basket and hanger. For example, disposed on a generator, the accessory carrying assembly may include outlets for providing power connections, fuses, and/or controls which are used to determine the operation of the generator.
It is further contemplated that the basket 205, in either the wire form or closed form, may include a cover connected with the basket 205 by at least one fastener. The cover may completely encompass one side of the basket 205 providing a closed assembly or may partially encompass one side leaving access available without having to move or remove the cover. The cover may be composed of various materials, such as metal, plastic, composite, and the like. Further, the cover may provide a transparent, translucent, and the like, cover enabling an operator of the air compressor 100 to see what is inside the basket 205 without having to move or remove the cover. The cover may be enabled like a door to provide access to the accessories stored within the basket 205. The cover/door may open in various directions, for example if the cover is on a top side of the basket 205 then it may open towards the back of the basket 205 so as to assist in easy access to accessories stored within. If the cover/door is on a long side of the basket 205 then it may open towards one side of the basket 205 to allow access to the accessories stored within.
The basket 205 is connected with the handle 110 through a plurality of mounting members included on the basket 205 connecting with a plurality of fastening points disposed with rubber grommets included within the handle 110. The rubber grommets may assist in reducing the wear between the handle 110 and the basket 205 caused by various factors, such as frictional contact due to vibration. The plurality of mounting members may be formed of metal, plastic, or other rigid material, to securely engage the basket 205 with the handle. The number, location, and configuration of the plurality of mounting members may vary to accommodate the connection of the basket 205 with the handle 110. The plurality of mounting members allow for the handle 110 to be reversibly connected to the frame 102 without diminishing the ability to mount and store the basket 205 on the air compressor 100.
The number, location, and configuration of the plurality of fastening points may vary to accommodate to the mounting members being employed with the air compressor 100.

Thus, the basket 405 of the accessory carrying assembly is a remotely transportable assembly relative to the air compressor 300. This may be advantageous on work sites where the air compressor is unable to be taken to the location the accessories are needed.
The configuration of the basket 405 including the handle 440 is advantageously constructed to promote the ease of use of the accessory carrying assembly, wherein, the connection and removal of the basket 405 with the frame 302 is more easily accomplished. The mounting members and extensions provide an increased ease of use by making the connection of the basket 405 with the handle 310 of the frame 302 simpler. The mounting members and extensions do not require the use of additional fasteners or mechanical connectors in order to securely seat the basket upon the handle 310. In addition, the fastening points including the rubber grommets further promote this ease of use by promoting the ease with which the mounting members may be inserted and removed.
The configuration of the basket 405 further promotes the stability of the connection between the basket 405 and the handle 310 of the frame 302. The basket 405, having dimensions which enable it to fit between the bars of the handle 310, utilizes the handle 310 as a support mechanism when connected together. Thus, the basket 405 is provided lateral support not only by the mounting members connection with the fastening points but by the configuration of the bars of the handle 310 as well.
The hanger assembly 450 is a wire form assembly having a first hanger 455 and a second hanger 460 integrally connected and used to store items, such as the hose used with the air compressor. The first and second hangers may be identical in configuration and mounted adjacently on the frame assembly in a one hundred eighty degree orientation relative to one another. It is understood that the first and second hangers may be configured differently from one another while maintaining the ability to perform the function of the hanger assembly.
The first and second hangers are coupled with the frame 302 through the first fastener 350 and second fastener 352. It is contemplated that the first and second hangers may be connected with the frame 302 using other fastening assemblies, such as clips, straps, compression lock systems, bolts, screws, and the like, which are not a part of the first and second fastener assembly of the air compressor.
The hanger assembly 450, similar to the basket 405, is formed of wire formed first and second hangers. The hangers are generally “U” shaped and are connected on the bottom by cross supports to provide structural integrity. In operation, a hose or other item may be wrapped around the bottom of the “U” and within the arms of the “U”. It is contemplated that other forms and configurations may be employed for the hangers, such as a single “T” bar form which may connect with one or both sides of the frame assembly. It is further contemplated that the hanger assembly 450 may be operationally coupled with various other assemblies, such as generators, other hydraulic pumps, and the like.
The hanger assembly 450 may be formed to include various other devices and capabilities. For example, the hanger assembly 450 may be coupled with a generator including outlets, fuses, and selectors which determine operation of the generator. Further, the hanger assembly 450 may provide a recessed area for storing accessories within.
