Abstract
An attachment assembly to convert an existing leaf blower into a device for drying vehicles. The attachment assembly includes several interchangeable modular sections, including an adapter section configured to attach to the air outlet of an existing commercial leaf blower. Other sections include air outlet nozzle sections, an extender section, and a weighted section. The inlet side of the nozzle sections, extender section, and weighted section as well as the outlet sides of the adapter section, extender section, and weighted section are uniform so that any of the outlets may be mated with any of the inlets. This allows any configuration of sections desired to be achieved. The adapter section may have a filter placed in the air stream to prevent debris from being blown into the vehicle and damaging the exterior of the vehicle.

[0092] The adapter section (200), as shown in
[0093] The adapter attachment clip (216) has an adapter clip spring (228), an adapter clip tooth (220), an adapter clip body (212), a clip pin (552), and an adapter clip release button (224). The adapter clip release button (224) is positioned over the adapter clip spring (228) so that the spring provides a force radially outwards from the adapter tube. The clip body connects the adapter clip release button to the adapter clip tooth (220). The clip pin (552) is between the clip release button and the adapter clip tooth and provides a fulcrum for the adapter clip body (212). The adapter attachment clip (216) is designed to engage a raised geometric shape (120) on the blower outlet tube (104). The adapter attachment clip (216) is self-locking so that it automatically engages the attachment feature (120) when the adapter (200) is placed on the blower outlet tube (104) without the need to depress the clip release button (532). However, the attachment clip (528) may not be removed unless the clip release button (532) is depressed. The adapter clip spring (228) provides a biasing force against the underside of the adapter clip release button (224) which forces the adapter clip tooth (220) down. As the adapter section (200) is slid over the blower outlet tube (104), the adapter clip tooth (220) has an angled leading edge (221) that forces the adapter clip tooth (220) to raise over the attachment feature (120). When the adapter clip tooth (220) passes the attachment feature (120), the force from the adapter clip spring (228) pushes the adapter clip release button (224) up and the adapter clip tooth (220) down which creates a secure engagement and prevents the adapter section (200) from being removed from the blower outlet tube (104) unless the adapter clip tooth (220) is raised by depressing the adapter clip release button (224).
[0094] As shown in
[0095] The conical nozzle (500) has a conical nozzle inlet (508) in which air from the adapter section (200) enters the conical nozzle (500) and a conical nozzle outlet (512) where air exits the conical nozzle (500). The conical shape of the nozzle body (504) causes the airflow generated by the blower (100) to compress into a smaller area and increases the flowrate of the air exiting the nozzle outlet (512).
[0096] A safety tip (516) is preferably located proximate the conical nozzle outlet (512). The safety tip (516) is constructed of a relatively soft flexible material that will not scratch the surface of a vehicle being dried upon contact. The safety tip (516) may be composed of rubber, polymer, silicone, or other similar soft, flexible material. The safety tip (516) may be over-molded onto the rim of the nozzle outlet or may be frictionally engaged or attached with an adhesive.
[0097] In some embodiments, a screen or filter (300) is configured to be located in the air flow path between the blower and the end outlet of the dryer assembly. More particularly, the filter (300) may be located between the blower outlet (108) and the adapter section (200) as shown in
[0098]
[0099] The rotatable nozzle body (720) has pin holes (708) for accepting a pin that connects the rotatable body (720) to the pivoting nozzle section (724). The rotatable nozzle body (720) ends in a partially spherical outer surface (716) having an opening (732). The opening (732) is somewhat slot shaped to direct air flow from a cylindrical flow pattern of the upstream to a more flat pattern corresponding to the articulating nozzle outlet (740). The overlap between the partially spherical outer surface (716) of the rotatable nozzle body (720) and the partially spherical inlet section (712) of the pivoting nozzle piece (724) prevents most of the air from escaping through the connection and forces the air out of the articulating nozzle outlet (740). The pivoting nozzle section (724) then transitions from the partially spherical inlet section (712) into the tapered body (736) which terminates in the articulating nozzle outlet (740) and optionally a safety tip (516). The cross section of the tapered body (736) where the tapered body connects to the partially spherical inlet section (712) is smaller than the cross section of the articulating nozzle outlet (740) such that the air passing through the tapered body is dispersed over a wider area.
[0100] The articulating nozzle (700) connects to an upstream section by having the nozzle connection collar (536) overlapping the adapter connection collar (232) and securing the connection with the use of at least one nozzle attachment clip (528) as discussed above. This connection allows the articulating nozzle (700) to rotate around the upstream section. This rotation allows the articulating nozzle (700) to have two degrees of motionrotation of the articulating nozzle relative to the adapter connection collar (232) and a pivoting nozzle section (724).
[0101]
[0102] The weighted section (400) is designed to counter the tendency of the blower to point upwards during use due to the weight of the blower. The force of the air leaving a nozzle can create rotation in the blower about the handle and cause it to point towards the sky rather than the vehicle surface. The plastic tubes, by themselves, do not provide much weight to counter the blower force. Therefore, the added weight provided by the weighted section (400) will prevent the blower from rotating during use and provide more control for the user. Additionally, the farther downstream the weighted section is from the blower, the more resistance will be provided. Thus, it is not required that the weighted section (400) be attached directly to the adapter section (200). Certain blowers may be more prone to raising than others, and so placing the weighted section (400) farther downstream may be advantageous.
[0103]
[0104]
[0105]
[0106]
[0107] As shown by
[0108] It is to be understood that any of the adapter connection collars (232) may be attached to any of the nozzle connection collars (536). Thus, while only some configurations are described and shown in the figures, any configuration that begins with the adapter section (200) and ends with either the conical nozzle (500) or the articulating nozzle (700) is possible. Thus, a configuration of the adapter section (200) connected to the extender section (600), which then connects to the weighted section (400) and ends in the conical nozzle (500) is possible. Alternatively, the adapter section could have the weighted section (400), then the extender section (600), then the articulating nozzle (700). Additionally, multiples of the weighted section (400) and extender section (600) are possible. Specifically, when drying larger vehicles, such as RV's and campers, it would be beneficial to combine multiple extender sections (600) together so that the blower's range is extended and a larger effective range is achieved.
[0109] It is therefore to be understood that while different embodiments are herein set forth and described, the above and other modifications and changes may be made in the construction and arrangement of elements as well as intended use of the apparatus without departing from the spirit and scope thereof. For example, the component parts may connect on the inside, not the outside, the clips may be different, the diameters may be different, the nozzle shape may be different, the length of the sections may be different, etc. The above configurations show the nozzle attachment clips going over the adapter connection collar; however, it is contemplated that the nozzle connection collars fit within the adapter connection collars. The above embodiments and configurations show the nozzle attachment clips contained on the nozzle connection collar and the clip attachment feature on the adapter connection collar; however, the clips may be found on the adapter connection collar and the clip attachment feature may be on the nozzle connection collar. Alternatively, it is contemplated that both the adapter connection collar and the nozzle connection collar have both nozzle attachment clips and clip attachment features. Additionally, the clip attachment feature shown in the above embodiments is a recessed groove in the collar; however, any suitable method for attaching the collar may be used. These include a ball and groove system, a raised feature similar to the one shown on the blower tube, magnets, a high friction surface to hold the connection together, a notch and groove, and other methods that would be obvious to one having skill in the art. While the figures show that there are two nozzle attachment clips, there may be one nozzle attachment clip or more than two nozzle attachment clips. Alternatively, there may be no nozzle attachment clips as described in certain embodiments such as those having a radial notch and groove attachment feature, a frictional attachment, or a biased attachment. There may also be a loop or ring attached to the each of the adapter section, the extender section and the nozzle sections to accommodate a shoulder strap. The strap would be connected to any of these loops and to the blower to facilitate carrying and use of the device. This loop or ring may consist of an arcuate extension extending radially out from each of these sections. Additionally, the airflow outlet of the nozzles may vary beyond what is shown in the accompanying drawings to provide a focused narrow airflow or a wider coverage area a would be appreciated by those of skill in the art upon reading the present disclosure. These nozzles would be useful for drying the tops of taller vehicles without requiring a ladder or platform.
[0110] Although the preferred embodiments according to the present disclosure have been described herein, the above description is merely illustrative. The embodiments disclosed do not limit the scope of the present disclosure. Further modification of the embodiments disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.

The foregoing is not intended to limit the invention to the form or forms disclosed herein. In the foregoing Detailed Description for example, various features of the invention are grouped together in one or more embodiments. The features of the embodiments may be combined in alternate embodiments other than those discussed above.
[0112] Moreover, though the description of the invention has included description of one or more embodiments and certain variations and modifications, other variations, combinations, and modifications are within the scope of the invention, e.g., as may be within the skill and knowledge of those in the art, after understanding the present disclosure. It is intended to obtain rights which include alternative embodiments to the extent permitted, including alternate, interchangeable and/or equivalent structures, functions, ranges or steps to those claimed, whether or not such alternate, interchangeable and/or equivalent structures, functions, ranges or steps are disclosed herein, and without intending to publicly dedicate any patentable subject matter.
