(14) According to an aspect, the handle portion 12 may consist of a pair of opposing grip portions 30, 32 that extend generally perpendicularly from either opposing side surface 20, 22 of the nose portion 14. Each grip portion 30, 32 may be formed as a single piece or from multiple pieces. According to an aspect, the grip portions 30, 32 may each be enlarged and tapered like conventional handle bars to allow a user to readily grip them in order to easily manipulate the tool. According to an aspect, the grip portions 30, 32 may be formed from a smooth material such as wood. However, the grip portions 30, 32 may be formed of a variety of other suitable materials such as a plastic. As shown, the grip portions, 30, 32 may each have a generally cylindrical shape that tapers away from the nose portion 14. According to an aspect, the grip portions 30, 32 may include inner support members 34, 36 that are secured to the second end 18 of the nose portion 14 at a respective side surface 20, 22 with outer members 38, 40 secured around the support members 34, 36.

(15) FIG. 5 is an illustration of an exemplary media element 50 to which a treatment head is to be attached in accordance with an aspect of the disclosure. The wash media element 50 may be configured to be secured to a hub of a vehicle wash component. It will be appreciated that the wash media element can have varying configurations, lengths or orientations as needed. As shown, the media element 50 may consist of an elongate structure, as is discussed in more detail in Applicant's U.S. Pat. No. 8,990,993, entitled Vehicle Wash Component, the disclosure of which is hereby incorporated by reference as though set forth fully herein. The media element may alternatively be constructed of other suitable materials.

(16) According to an aspect, the media element 50 may be constructed of two separate portions that are adhesively bonded together with a cord or bead welt at one end for mounting in a media securement member. Alternatively, the media element 50 may be formed as single pieces by conventional forming processes. As is shown, the media element 50 may be utilized in a vehicle wash brush in a tunnel vehicle wash facility. Alternatively, the media element may be employed in a brush for a rollover vehicle wash where the rotation direction of the brush reverses with each pass of the rollover gantry over the vehicle being washed.

(17) As shown, the media element 50 can include a front face 52, a rear face 54 and a pair of edge walls 56 that extend between the front and rear faces 52, 54 and has a thickness (T) defined between the front and rear faces 52, 54 (See FIG. 10). According to another aspect, each media element 50 may be formed of a self-supporting material such that it substantially retains a constant shape between a first end 58 and a second end 60 when the hub to which they are attached is rotated. For example, the media element 50 may be made of an elastomeric polymer type material such as ethylene-vinyl acetate (EVA). It will be appreciated that the media elements 50 could have a variety of different shapes and may be formed of a variety of different types of suitable materials.

(18) According to an aspect, each media element 50 may further define a plurality of elongated slots 62 that extend generally from the second end 60 toward the first end 58 along a portion of the media element 50 to divide it into a plurality of elongated fingers 64 disposed in spaced and parallel relationship with one another. The elongated slots 62 can extend fully between the front face 52 and the rear face 54 at any angle. As shown in the figures, the elongated slots 62 may extend generally linearly, however, it should be appreciated that they could extend in other shapes, e.g., an arc or zigzag pattern. As such, the fingers 62 may have other shapes as well. According to a further aspect, the elongated slots 62 may be oriented generally parallel to the edge walls 56, however, they may also be angled or sloped. Additionally, more or fewer slots 62 may be employed.

(19) As shown, according to an aspect, the slots 62 may be formed by the removal of material such that they may be defined by the absence of material. In other words, the opposing edges of the elongated fingers 64 may be spaced apart from one another by the slot 62. It should be appreciated that during rotation of the media elements 50, the slots 62 may advantageously allow components of the vehicle to pass therethrough between the fingers 62 to ensure that the vehicle is evenly engaged by the fingers 62 during each pass of the media element 50 and to ensure that the components are not snagged and damaged or torn from the vehicle. For example, an antenna of the vehicle may pass through the slot 62, thus allowing the fingers 64 to contact and remove debris from the surfaces of the vehicle on opposing sides of the antenna. Furthermore, it should be appreciated that the fingers 64 may bend/pivot relative to one another during contact with this vehicle to allow non-planar structures of the vehicle to be evenly contacted and cleaned by the fingers 64, as discussed herein.

(20) As shown, each of the elongated fingers 64 of the media element 50 may also include a plurality of crosswise apertures or niches 66 that extend generally perpendicularly to the elongated slots 62. The niches 66 may be configured such that they may receive, for purpose of attachment, a treatment head 68 to connect it to the wash media element 50. According to an aspect, each of the treatment heads 68 may have a forward face 70 and a rearward face 72 and may extend between a contact portion 74 and a tongue portion 76. Like the media element 50, each of the treatment heads 68 may be formed of a shape retaining material including, but not limited to, an elastomeric polymer type material such as ethylene-vinyl acetate (EVA). It will be appreciated that the treatment heads 68 could be formed from a variety of different materials. According to an aspect, each treatment head 68, like the media element 50, may be self-supporting along their lengths. This self-supporting characteristic can serve to apply a pressure force on the vehicle to provide improved cleaning.

(21) According to another aspect, the tongue portion 76 can include an enlarged head portion 78 that assists in retaining the treatment heads 68 secured to the wash media element 50. According to an aspect, the head portion 78 may be sized so that its width (W.sub.h) is larger than the width (W.sub.n) of the niche 66 to which it is inserted to ensure attachment during operation. The enlarged head portion 78 can include a rounded bottom surface 80 that terminates in a pair of opposing shoulder portions 82. According to a further aspect, the head portion 78 may be sized so that its width (W.sub.h) is less than the width (W.sub.f) of the elongated finger 64 to which it is attached. It will be appreciated that the treatment heads 68 may have a variety of different shapes and configurations.

(22) According to another aspect, the contact portion 74 of each treatment head 68 may be configured to contact the vehicle to remove debris and water therefrom. Each contact portion 74 may include a plurality of bristle portions 84 that may have various widths and lengths. The bristle portions 84 are preferably independently moveable with respect to one another to provide increased cleaning capabilities. As the bristle portions 84 move independent of one another, they can expose side portions of each bristle portion that can contact a vehicle and effect cleaning. As shown, according to one aspect, nine (9) individual bristles may be employed. However, it will be appreciated that any number of bristle portions 84 may be employed. It will be appreciated that the treatment heads 68 may extend from the crosswise niches 66 at any angle relative to the fingers 64. For example, the treatment heads 68 may extend from the niches 66 with the forward face 70 disposed at approximately a 45 degree angle relative to the front face 52 of the finger 64. According to another example, the treatment heads 68 can extend from the niches 66 with the forward face 76 of the treatment heads 68 disposed at approximately a 90 degree relative to the front face 52 of the finger 64. It will be appreciated that the treatment heads 68 could extend at other angles as desired.

(23) According to a still further aspect, the treatment heads 68 may be formed such that the contact portion 74 of each of the treatment heads 68 has a width (W.sub.cp) that is greater than the width (W.sub.f) of the elongated finger 64 to which it is attached such that it can extend past the edges of the fingers 64 and overlie at least part of the slots 62. It should be appreciated that positioning the contact portions 74 in this overlapping fashion over the slots 62 advantageously prevents skunk stripes on the vehicle at the location of the slots 62 between the fingers 64. More specifically, the bristles portions 84 can provide a contact point with the vehicle that would otherwise not be present because of the presence of the slots 62. As shown, the treatment head 68 can have a pair of sides 86 that generally converge from the contact portion 74 toward to the head portion 78 such that the width decreases. The sides 86 can converge in a generally arcuate manner in order to avoid any sharp or edge portions. According to an aspect, the tongue portion 76 that connects the contact portion 74 to the head portion 78. The tongue portion 76 may have a sufficient width to ensure that the contact portion 74 exerts a force onto a vehicle exterior. The tongue portion 76 thus can exert a spring force to keep the contact portion 74 engaged with the vehicle exterior.

(24) FIGS. 7 through 9 illustrate an exemplary method for attaching a treatment head 68 to a wash media element 50 in accordance with an aspect of the present disclosure. According to an aspect, although not expressly shown in FIGS. 7 and 8, the nose portion 14 of the tool 10 may be passed through the niche 66. Once the nose portion 14 is exposed on the front face 52, the treatment head 68 may be placed in communication with the tool 10 in order to effect attachment thereof to the media element 50. Specifically, as shown in FIG. 7, after the nose portion 14 has passed through the niche 66, the head portion 78 of the treatment head 68 may be passed through the slot 24 in the nose portion 14 of the tool 10. According to an aspect, the head portion 78 may be oriented such that the width (W.sub.h) of the head portion 78 is oriented in the longwise or height (H.sub.s) direction of the slot 24 allowing the head portion 78 to pass therethrough as its width (W.sub.h) is smaller than the height (H.sub.s) dimension of the slot 24 (W.sub.h<H.sub.s). In this configuration, the tongue portion 76 may reside in the slot 24 with the head portion 78 located on one side 20 of the slot 24 and the contact portion 74 on the other side 22 of the wash media element 50. It will be appreciated that the head portion 78 may be passed through the slot 24 in a variety of different ways.

(25) Referring now to FIG. 8, according to an aspect, the treatment head 68 may be rotated within the slot 24 about 90 degrees (as represented by the arrow R) such that the width dimension of the head portion 78 may be oriented in the width dimension of the slot 24. According to another aspect, as the width (W.sub.h) of head portion 78 is greater than the width (W.sub.s) of the slot 24 in the nose portion 14 (W.sub.h>W.sub.s), the treatment head 68 is prevented from decoupling from the slot 24 and thus the tool 10. According to another aspect, the tongue portion 76 may be sized and formed of a compressible material such that it is wedged in the slot 24 to fixedly secure it therein, but can be easily uncoupled. It will be appreciated that the tongue portion 76 may have a variety of different widths and configurations. It will also be appreciated that the tongue portion 76 may be retained in the slot in a variety of different ways.

(26) According to another aspect and with reference to FIG. 9, once the treatment head 68 is secured in the slot 24, the nose portion 14 of the tool 10 may be pulled back through the niche 66 in the wash media element 50 (i.e., from the front face 52 to the rear face 54). As the nose portion 14 is passed back through the slot 24, the head portion 78, which is coupled in the slot 24 also passes through the niche 66. According to an aspect, as the head portion 78 enters the niche 66, the shoulder portions 82 are able to slightly deflect inwardly toward the tongue portion 76 to allow the head portion 78 to pass therethrough. Once the head portion 78 exits on the rear face 54 of the slot 24, the nose portion 14 can be rotated to allow the head portion 78 to exit the slot 24. Additionally, once the head portion 78 exits onto the rear face 54 of the slot 24, the shoulder portions 82 can deflect back or return to their normal position. As the width (W.sub.h) of the head portion 78 is greater than the width (W.sub.n) of the niche 66, the shoulder portions 82 can engage the rear face 52 of the wash media element 50 to prevent the head portion 78 from passing back through the niche 66. This serves to keep the treatment head 68 secured to the wash media element 50 in a manner shown in FIG. 10. It will be appreciated that a variety of other methods for employed for securing the treatment head 68 to the media element 50 with the tool 10, including attaching the treatment head 68 to the slot before inserting the nose portion 14 into the niche.

(27) According to a further aspect, prior to coupling the treatment head 68 to the tool, the treatment head 68 may be lubricated to assist in its entry into the niche 66. For example, the treatment head 68 may be soaked in a soapy water solution. The treatment head 68 could also be soaked in a variety of other suitable fluids or the like. Additionally, the wash media element 50 could be soaked in solution for the same person.
