Embodiments of the present invention generally relate to drying a vehicle, and more specifically to drying a vehicle using a handheld blower.
Handheld blowers used for yard and other outdoor work are common. Invented in the late 1950's, they have gained popularity and versatility overtime. Originally, blowers were used to spray chemicals in the agricultural industry and now have many uses, from blowing leaves into piles, to cleaning gutters and surfaces of debris. They are versatile instruments and readily available at most hardware, lawn and garden, and big box stores. Additionally, with the introduction of battery powered lawn care tools, the restrictions of a power cord are eliminated and blowers may now be used in more places and for more end uses.
With over 250 million motor vehicles, the United States has one of the world's highest vehicle-per-capita rates with almost 1 vehicle for every person in the country. In order to maintain proper care of their vehicles, vehicle owners must wash and clean the exterior of the vehicles to prevent rust and deterioration of the paint from salt and other damaging materials. Maintaining a clean vehicle also prevents the user from becoming dirty when entering and exiting the vehicle. Further, many users take pride in keeping their vehicle clean and aesthetically pleasing. For these purposes, it is important to dry the vehicle after washing to remove residual dirt and chemicals and prevent the formation of water marks on the vehicle surface. Drying the vehicle involves either significant manual labor by the owner using towels or chammies or paying for an automated car wash that utilizes large industrial blowers for blow drying the vehicle or manual laborers to hand dry the vehicle. Towel drying a vehicle is tedious and may be difficult depending upon the size of the vehicle and the owner. Moreover, drying a car with a cloth can cause micro scratches on the vehicle's paint. Automated car washes with industrial drying blowers, while involving little to no labor, use high power water jets, large contact roller brushes or pads which may also cause damage to the vehicle's exterior. Automated car washes also cost money to use. Thus, car owners have long faced the dilemma of choosing between allowing water spots to form on the car, manually drying their vehicles themselves with towels, paying for an automated car wash with drying, or paying others to manually dry the vehicle.
There has thus been a long felt need for a vehicle dryer that is inexpensive, readily accessible and does not cause damage to the vehicle's exterior. With the amount of vehicles in the United States and worldwide, there is a large market for a device that it inexpensive and can quickly dry a vehicle with minimal user effort without damaging the vehicle's exterior surface. Despite the large need and demand, and given the widespread availability of lawn and/or debris blowers for decades, there has been a surprising failure to successfully develop a vehicle drying blower using a lawn blower.
The present disclosure inexpensively solves the problem of drying vehicles without damaging the paint by providing a drying attachment for use with handheld yard blowers. According to aspects of the present disclosure, in one embodiment the attachment includes an adapter configured to attach to a pre-existing yard blower and a nozzle configured to connect to the adapter. The adapter has a first end that is configured to attach to a pre-existing blower's outlet and a second, opposite end that is designed to connect to a nozzle or, in other embodiments, a plurality of other component pieces. The remaining component sections comprise a variety of extenders, other nozzles, and a weighted section to assist a user in counterbalancing the weight of the blower.
Existing commercial blowers typically have a removable blower tube which is connected to a fixed or non-removable air outlet port of the blower by some sort of attachment feature. According to aspects of the present disclosure, a variety of multiple adapters are available wherein the first end is specially configured to interconnect with the particular outlet port of different blower brands, e.g., Black & Decker, DeWalt, Ryobi, EGo, Husqvarna, Toro, Snapper, Echo, and Milwaukee, among others, while the second, opposite outlet end of these various adapters will be identical in order to interconnect with the various nozzles and other components comprising the different embodiments of a drying adapter assembly. The attachment feature may be a raised edge, a recessed groove, a notch, a locking element, or similar associated with the non-removable outlet port. The adapter is configured to engage this attachment feature at the adapter section inlet and provide a new downstream outlet for the air expelled from the blower. As noted, in preferred embodiments, the adapter outlet has a common size to mate with all other downstream sections, which are discussed below, thus reducing manufacturing costs and increasing the configurations available to the end user.
In at least one embodiment, the adapter section includes an in-line filter. The filter may be disposed at the adapter section outlet, or anywhere along the body of the adapter while in the airflow path. The filter may comprise a mesh which allows air to flow through the device but prevents the expulsion of small debris that could scratch or mar the surface of the vehicle. The mesh would be sized to prevent the passage of debris without restricting airflow significantly. The filter may also be removable and include different sized configurations that prevent the expulsion of different sized debris ranging from small particles such as pieces of leaves and other debris, to larger debris such as sticks and pine needles.
In one embodiment, a conical nozzle is connected to the outlet of the adapter section. The conical nozzle attaches to the outlet of the adapter section via a number of attachment clips. A clip may be on either the adapter section, the nozzle section, or both and is configured to engage a clip receiving feature associated with the opposite component section. The clip receiving feature may include a raised edge, a recessed groove, a notch, a locking element or some other structure known to those of skill in the art and used to secure one component in a mating position with a second component.
Another embodiment comprises the adapter section with a selectively articulating nozzle. The articulating nozzle pivots in at least one direction and may also rotate. The articulating nozzle may be composed of two separate sections, an inlet section configured to mate with the outlet end of the adapter or the outlet end of an extender tube (discussed herein), and an outlet section. The inlet section is generally tubular and in at least one embodiment has a first or inlet end that fits over the outlet end of an adapter or extender tube, and a second end, opposite the first end, having a partial spherical outer surface having a slot shaped aperture to allow air to pass through the inlet section and into the outlet section. According to aspects of the present disclosure, the inlet section is capable of rotating three-hundred sixty degrees in either direction relative to the adapter or extender tube.
The outlet section of the articulating nozzle has a first, upstream end with a partial spherical surface which engages and covers the partial spherical end of the inlet section when the two sections are joined. A pair of pins, rivets or screws connect the outlet section to the inlet section wherein the partial spherical section of the inlet section and the partial spherical cover section of the outlet section mate or nest and the outlet section is free to pivot about the pins and redirect airflow as a result. The outlet section has a wedge-shaped pivoting nozzle section extending from the partial spherical cover portion and optionally ends in a rubber safety tip. This configuration allows the air flow to be directed up to 45 degrees off the longitudinal axis of the airflow. The articulating nozzle section may be attached by clips located on the nozzle section, the adapter section, or both which engage a clip attachment feature of the opposite section. The clip attachment feature may be a raised edge or a recessed groove. The articulating nozzle may be able to rotate around the adapter section, allowing two degrees of motion.
In another embodiment, an extender section connects the adapter section with either of the nozzle sections. The extender is a hollow tube having a certain length and is intended to extend the location of the air outlet from the blower in order for a user to reach and dry farther away portions of the vehicle. Multiple extender sections may be joined to extend the nozzle farther, for example, when drying larger vehicles such as campers and RVs. The extender has an inlet side that is configured to be connected to the adapter section by clips which engage a clip attachment feature on the corresponding section. The clips may be on the adapter section, the extender section, or both. The clip attachment feature may be a raised edge or a recessed groove. The outlet section of the extender section may be the same size as the outlet of the adapter section and therefore, be able to receive any of the other sections, except for the adapter section, discussed herein. The outlet section of the extender may have clips for attaching an additional section, or a clip attachment feature, or both.
In another embodiment, a weighted section may be joined with the other components to provide a counterbalance to the weight of the blower body and facilitate use of the blower as a vehicle dryer. The weighted section may be positioned between the adapter section and a nozzle section. The weighted section is configured to be connected to the adapter section by clips. The clips may be on either the weighted section, the adapter section, or both, and engage a clip receiving feature. The clip receiving feature may be a raised edge or a recessed groove. The weighted section may have a weighted collar between the weighted section inlet and the weighted section outlet. The weighted collar may be weighted by sand, metal, plastic, water, or other suitable dense material. The outlet of the weighted section may connect to an additional section by clips on either the weighted section, nozzle section, or both, which engage a clip attachment feature. The clip attachment feature may be on either the weighted section, the downstream section, or both, and is configured to engage a clip attachment feature. The clip attachment feature may be a raised edge or a recessed groove and may be on the weighted section, the nozzle section, or both.
Another embodiment of the invention comprises a safety tip for the nozzle sections. The safety tip is located on the outer edge or outlet end of the nozzle where the air flow is expelled from the device. The safety tip may be over-molded or attached by a friction fit or adhesive. The safety tip is composed of a soft material which may be rubber or some other soft polymer. The safety tip prevents the configured blower attachment from denting or scratching the surface of a vehicle upon contact.

The adapter section (200), as shown in
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).
As shown in
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).
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.
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
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.
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 motion—rotation of the articulating nozzle relative to the adapter connection collar (232) and a pivoting nozzle section (724).
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.
As shown by
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.
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.
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 discussion of the invention has been presented for purposes of illustration and description. 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.
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.
