DETAILED DESCRIPTION

The embodiments disclosed herein relate to improved hair styling brush systems. Professional hairstylists worldwide routinely employ a set tools considered essential to the shaping and styling of hair. Foremost among these are hair styling brushes, or hair brushes, and hand-held, electrically-heated "hairdryers", also known as "blow dryers". In the art of hairstyling, the hair styling brush is used to manipulate the hair as a flow of heated air generated by the hairdryer assists in setting the shape of the individual's hair.

Generally speaking, the hair brushes of the present disclosure comprise a plurality of bristles mounted within a resilient cushion member. The cushion member is engaged within a brush head portion that is joined to a hand-graspable handle. Additionally, the hair brushes of the present disclosure utilize at least one heat retention plate, or thermal plate, above and covering the resilient cushion member to assist shaping, shining, and drying of hair when the heat retention plate is heated with a blow dryer and placed in contact with hair during hair styling. The hair brushes of the present disclosure may also utilize a gap between the heat retention plate and the resilient cushion member. In use, the hair brushes of the present disclosure provide a user with greater thermal control during hairstyling procedures using heated air.

The concepts disclosed in the present disclosure may be implemented in a number of ways. One example implementation is illustrated in FIGS. 1 -18. Another example implementation is illustrated in FIGS. 19-21 . It is noted that while a particular brush shape is depicted and described in the figures, other brush shapes are envisioned, such as, for example, rectangular-shaped paddle brushes, oval-shaped brushes, etc.

FIG. 1 shows a perspective view, illustrating hair brush 102, according to an embodiment of the present disclosure. FIG. 2 shows an enlarged partial perspective view illustrating brush head portion 104 of hair brush 102. FIG. 3 shows a top view of hair brush 102. FIG. 4 shows a side view of hair brush 102. Hair brush 102 is one of a number of embodiments or implementations of hair brush system 100. One key feature of the hair brushes of hair brush system 100 is that they comprise a thermal plate to enhance the performance of the hair brush during use and to increase the durability of the components of the hair brush. The thermal plate, also referred to herein as a heat retention plate, assists shaping, shining, and drying of hair when heat is applied to the thermal plate using a blow dryer or similar device. The thermal plate advantages are numerous. The thermal plate allows shaping the hair (e.g., straightening, curling, giving a texture-wave effect, etc.) much more easily depending on how the brush is used on the hair. The thermal plate also substantially reduces blow drying time when blow drying the hair as the hot thermal plate contacting the hair causes the hair to dry faster. The thermal plate further lends more shine to the hair. When the scales on the surface of the hair are smoothed, or closed, by dragging the hot thermal plate in the direction of the scale closing (i.e. , brushing the hair from root to the ends), the "closed" scales result in a smoother surface which reflects light creating a shiny appearance. Shiny hair is desirable as it portrays a beautiful and healthy look. The thermal plate further improves the durability of the hair brush through reductions in the rates of thermal degradation within the constituent materials.

With reference to FIG. 1 and FIG. 2, hair brush 102 is depicted as a hand-held device for grooming and styling of hair. Hair brush 102 may be thought of as made up of three principal parts identified herein as handle portion 106, brush head portion 104, and bristle assembly 108, as shown.

Bristle assembly 108 comprises cushion member 110, thermal plate member 114 (also referred to herein as plate member 114 and also embodying herein a heat retention plate), and a plurality of bristles 112, as shown. It is noted that reference numerals identifying individual bristles 112 within drawings shall refer to like elements throughout. Bristle assembly 108 is depicted as able to be inserted into brush head portion 104, as best shown in the partially exploded view of FIG. 16. Bristles 112 of bristle assembly 108 project outwardly from cushion member 110, as shown. In an example implementation, cushion member 110 is constructed from a resilient material having rubber-like properties.

In an example implementation, plate member 114 comprises a thin but rigid shelllike structure that fits over the portion of cushion member 110 containing bristles 112, as shown. Plate member 114 comprises an arrangement of apertures 122 through which bristles 112 outwardly project, as shown. Plate member 114 provides the advantages noted above and protectively covers portions of cushion member 110 that are most directly exposed to flows of heated air from a hairdryer during use. Without thermal plate member 114, cushion member 110 would be exposed and would make contact with the hair not providing the noted advantages of the thermal plate. In the example implementation of FIG. 1 , plate member 114 is shown covering the upper surface of cushion member 110; cushion member is shown exposed at the top-end portion of brush head portion 104. The amount of covering that plate member 114 provides cushion member 110 may differ from the implementation depicted in FIG. 1 . For example, thermal plate may cover the entire cushion member including the top-end portion, thermal plate may cover a portion less than that depicted in FIG. 1 exposing one or more areas of the upper surface of the cushion member, etc.

Bristles 112 may be arranged in linear rows as shown, for example, in FIG. 3. In such an example implementation, within each linear row, bristles 112 may be evenly spaced at a bristle-to-bristle distance D1 of about 4 millimeters. Those with skill in the art will understand that the spacing between bristles may be altered. Bristles 112 of adjacent rows may be arranged in a staggered pattern, as shown in the top view of FIG. 3 and the side view of FIG. 4.

In one example implementation, hair brush 102 may have a longitudinal length L1 of about 210 millimeters and a maximum transverse width W1 at brush head portion 104 of about 36 millimeters. It is noted that this length and width may be altered to provide hair brushes of different sizes. Further, as noted above, hair brushes made according to the teachings of the present disclosure may be implemented in a number of different shapes.

In an example implementation, bristles 112 of bristle assembly 108 may be arranged in seven spaced-apart rows that are generally oriented in parallel alignment with the longitudinal axis 103, as shown. In one of the various implementations of hair brush system 100, a smaller five-row arrangement of bristles may be implemented. In yet another of the various implementations of hair brush system 100, a larger nine-row arrangement of bristles may be implemented. In still other various implementations of the hair brush system 100, other numbers of rows of bristles or bristle arrangements may suffice.

Handle 106 facilitates comfortable grasping and manual manipulation of the hair brush during use. In this regard, handle portion 106 may comprises at least one ergonomically-designed graspable shape, as shown. The smoothly-tapered "teardrop" profile depicted in FIG. 3 is one of the various implementations of a handle configuration of a hair brush of hair brush system 100.

FIG. 5 shows a back-end view of hair brush 102 and FIG. 6 shows a front-end view of hair brush 102. Referring to the illustrations of FIG. 5 and FIG. 6, both cushion member 110 and the thermal plate member 114 comprise a rounded convex profile when assembled within brush head portion 104, as shown. The rounded convex profiles of cushion member 110 and the thermal plate member 114 assist in maintaining gap 135 discussed further below. The rounded convex profile is further beneficial in facilitating the execution of hair styling techniques. In various implementations of hair brush system 100, the profile of thermal plate member and cushion member may be other than rounded convex, for example, the profile may be square-like or rectangular-like. In other various implementations of hair brush system 100, the profile of the cushion member may differ from the profile of the thermal plate so long as there is a gap maintained between the cushion member and the thermal plate member.

In the implementation depicted in FIG. 5 and 6, the rows of bristles 112 project outwardly in an orientation generally perpendicular to the outer face of cushion member 110, as shown. Thus, the rows of bristles 112 are splayed outwardly in a radiating pattern generally following the curved outer surface of cushion member 110, as shown.

FIG. 7 shows a bottom view of hair brush 102. The bottom view of handle portion

106 illustrates an example implementation of an optional teardrop-shaped concave region 123 formed within the bottom surface of handle portion 106, as shown. The bottom view shown in FIG. 7 illustrates that the brush head portion 104 has a closed back in an example implementation. According to other example implementations, brush head portion 104 may be oval shaped or in a rectangular paddle brush shape.

In an example implementation, handle portion 106 and brush head portion 104 may be integrally joined, as shown in FIG. 7. In an example implementation, handle portion 106 and brush head portion 104 may be formed monolithically using a single material. Handle portion 106 and brush head portion 104 may be constructed from a durable and lightweight material with the substantial use of rigid plastics being an example material. Handle portion 106 and brush head portion 104 may be molded as a single unit using known injection processes. Other materials of handle portion and brush head portion such as, for example, molded rubbers, milled plastics, vacuum-formed materials, metals, wood, glass, carbon-fiber, etc., and any combination of the foregoing, may suffice. Further, other assembly techniques, such as, assemblies formed by joining together two or more pre-molded parts, co-molding a resilient material over a rigid plastic substrate, etc., may suffice.

FIG. 8 shows an exploded view, illustrating various subcomponents of hair brush 102. FIG. 8 depicts hair brush 102 in a fully disassembled configuration. Visible in the exploded view of FIG. 8 is brush head portion 104, handle portion 106, and bristle assembly 108. Bristle assembly 108 is further subdivided into cushion member 110, bristles 112, and plate member 114, as shown.

In an example implementation, bristles 112 may be organized into separate bristle bars 116, as shown. In the example implementation illustrated in FIG. 8, 196 individual bristles 112 are shown grouped to form seven separate bristle bars 116. Each bristle bar 116 is shown to have a selected number of bristles 112 joined together by a continuous elongated base member 118, as shown. Bristle bars 116 may contain differing numbers of bristles 112 to accommodate the contoured shape of bristle assembly 108. As illustrated in FIG. 8, the two outermost opposing bristle bars 116A each contain 17 individual bristles 112. Inward of these are two longer bristle bars 116B, each one comprising 22 bristles 112, as shown. Inward of these are two additional bristle bars 116C, each one comprising 23 separate bristles 112, as shown. The central bristle bar 116D is the longest of the seven bars containing 24 bristles 112, as shown. Those with skill in the art will understand that, under appropriate circumstances, other arrangements of bristles and bristle bars may suffice.

In an example implementation, positioning of the bristle bars 116 within brush head portion 104 is controlled by cushion member 110. In an example implementation, cushion member 110 comprises an arrangement of perforations 120 into which the bristles of the previously-described bristle bars 116 are preferably engaged or integrated. It is noted that reference numerals identifying individual perforations 120 within drawings shall refer to like elements throughout.

Cushion member 110 in FIG. 8 is shown in an unfolded configuration that allows access to perforations 120 for placement of the bristles of bristle bars 116 therein. Once the bristles of bristle bars 116 are engaged within perforations 120, cushion member 110 is folded to allow the assembly to be inserted within brush head portion 104, as will be explained in greater detail herein.

In an example implementation, brush head portion 104 has a hollow interior cavity (also referred to as an open front portion) 140 to receive cushion member 110. Interior cavity 140 is depicted equipped with a set of structures designed to position and retain bristle assembly 108 within brush head portion 104. To this end, interior cavity 140 is shown with a pair of retention rails 142 located respectively along the interior side walls of interior cavity 140, as shown. The bottom end of interior cavity 140 is near the handle portion 106 and the top end of interior cavity 140 is at the opposing end. The retention rails 142 extend lengthwise along said brush head portion from the top end to the bottom end of the open interior cavity 140.

FIG. 9 through FIG. 1 1 further illustrate various features and arrangements of an example implementation of cushion member 110. FIG. 9 shows a top view of cushion member 110. FIG. 10 shows a sectional view through the transverse section 10-10 of FIG. 9. FIG. 1 1 shows a sectional view through the longitudinal section 1 1 -1 1 of FIG. 9. In reference to FIG. 9 through FIG. 1 1 and with continued reference to FIG. 8, perforations 120 (also referred to herein as apertures) within cushion member 110 may be arranged in longitudinal rows, with each longitudinal row configured to accommodate bristles from a single bristle bar 116. Such a structure and arrangement permits the bristles to flex at the base of the cushion member. In total, the example cushion member 110 illustrated in FIGS. 9-1 1 comprises 196 of perforations 120 to accommodate the 196 bristles 112 contained within the seven individual bristle bars 116 noted above. It is noted that the number of perforations may be increased or decreased. Corresponding perforations, or apertures, should be present in the thermal plate for passage of bristles.

In the present example implementation of hair brush system 100 illustrated in FIG. 9-1 1 , the central portion of cushion member 110, containing perforations 120, is shown to have an elongated portion, generally identified herein as bristle support member 124. Cushion member 110 is shown with a set of opposing arcuate ends 129 and an opposing pair of block-like side members 126 flanking each long edge of bristle support member 124

In an example implementation, each side member 126 is joined integrally with bristle support member 124 by a continuous "living" hinge 128 that is arranged in parallel orientation to longitudinal axis 103, as shown. Together, bristle support member 124, side members 126 and living hinges 128 form cushion member 110. Bristle support member 124, side members 126, and living hinges 128 may be molded as a single unitary structure.

The lower portion of each side member 126 is shown comprising a hollow channel 132 extending the length of the member (see also FIG. 13). The interior of each channel 132 is shown populated with an arrangement of projecting ribs 134 oriented substantially perpendicular to longitudinal axis 103 (see also FIG. 13). These sets of projecting ribs 134 interlock when the two side members 126 are brought together as cushion member 110 is folded, as will be described in greater detail in FIG. 14.

With specific reference to FIG. 9 and FIG. 10, the upper portion of each side member 126 is shown with a continuous recessed channel 136 extending substantially the length of the member, as shown. Recessed channel 136 is shown arranged in parallel orientation to longitudinal axis 103, as shown. Each recessed channel 136 engages a respective retention rail 142 located along the interior sides of interior cavity 140 of brush head portion 104 (see FIG. 8). When cushion member 110 is folded, the two opposing recessed channels 136 are positioned and aligned to enable bristle assembly 108 to slidably engage retention rails 142.

In an example implementation, each recessed channel 136 further comprises one half of an interlocking retainer 146 designed to assist in retaining bristle assembly 108 within brush head portion 104. Interlocking retainer 146 is shown with a first plurality of outwardly projecting teeth 148 longitudinally disposed within recessed channel 136. A second plurality of teeth 150 are shown longitudinally disposed on each retention rail 142 (see again FIG. 8). In the depicted implementation, teeth 148 and teeth 150 have a saw tooth shape enabling teeth 148 and teeth 150 to interlock, in a ratchet-type fashion, when recessed channels 136 are engaged on retention rails 142. Those of ordinary skill in the art will appreciate that teeth 148 and teeth 150 could be of different shapes and profile, such as rounded or square, so long as the "teeth" can be placed in interlocking relationship. Interlocking retainer 146 is configured to retain bristle assembly 108 within brush head portion 104. Such arrangement at least embodies herein a cushion-member- to-brush-head-portion locking system.

FIG. 12 shows a sectional view, through the transverse section 12-12 of FIG. 13, illustrating the sectional profile of thermal plate member. FIG. 13 shows a perspective view illustrating various subcomponents of brush head portion 104. In FIG. 13, the subcomponents of bristle assembly 108 have been rotated, relative to the view of FIG. 8, to show the opposing (lower) surface structures of the constituent components. For clarity of description, only a single bristle bar 116 is shown in FIG. 13.

In reference to FIG. 12, according to an example implementation hereof, thermal plate member 114 comprises a relatively thin "shell-like" structure having a cross- sectional profile closely matching that of cushion member 110 when cushion member 110 is in the folded configuration (see also FIG. 14 and FIG. 15). Thermal plate member 114 provides heat to hair when hair is placed in proximity of the thermal plate member (when also applying heat to the brush with a blow dryer) and to protectively cover the outer portions of cushion member 110 that are most directly exposed to flows of heated air from a hairdryer, namely, bristle support member 124. In such an implementation, thermal plate member 114 limits the volume of heated air reaching the outer surface of cushion member 110 when the apparatus is used with a hair dryer.

Thermal plate member 114 is preferably constructed from a material having high thermal conductivity. Thermally conductivity materials suitable for use in the construction of plate member 114 include metals and ceramics, including ceramic coatings. In an example implementation, plate member 114 is constructed from a metallic material. Preferred metallic materials include aluminum and copper. Steel may also be used to construct thermal plate member 114. In implementations of the hair brush of the present disclosure, a physical air gap 135 is located between the underside of the plate member 114 and outer surface of cushion member 110 (see also FIG. 15). The metallic, or similar, material forming the plate allows for greater thermal control during hairstyling procedures using heated air.

The thickness of the metallic material forming plate member 114 depends on the material selection. In an example implementation, the metallic material forming plate member 114 comprises an aluminum alloy having a thickness X1 of about 0.4 millimeters.

In an example implementation, the metallic material forming plate member 114 may have a corrosion-resistant finish. Such finishes may include plating, anodizing, painting, or a protective coating including ceramic coatings imparting ions or ionically- charged molecules to the hair. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, other materials, such as, for example, cermets, polymer-graphite composites, thermally conductive polysulfone compounds, etc., may suffice.

In an example implementation, apertures 122 of plate member 114 may be arranged in positions complementary to perforations 120 of cushion member 110. In total, plate member 114 shown comprises 196 apertures 122 to accommodate the 196 bristles 112 contained within the seven previously noted bristle bars 116. In the presently discussed example implementation, each aperture 122 may have a diameter D4 of about 3.3 millimeters. FIG. 14 shows a sectional view extending transversely through cushion member 110 illustrating cushion member 110 in a partially assembled and folded configuration. Visible in FIG. 14 are side members 126, central bristle support member 124, living hinges 128, and bristle bars 116. Bristle assembly 108 may be assembled by first engaging the plurality of bristle bars 116 within perforations 120 of bristle support member 124. Subsequently, side members 126 are folded under bristle support member 124 to capture and resiliently support the plurality of bristle bars 116 engaged therein. The folds within cushion member 110 occur along living hinges 128, as shown.

FIG. 15 shows a sectional view, through the section 15-15 of FIG. 3, illustrating the completed bristle assembly 108 engaged within brush head portion 104 of hair brush 102. In the assembled apparatus shown, the two side members 126 of cushion member 110 are brought into contact resulting in the inter-engagement of the opposing sets of projecting ribs 134, as shown. The two arcuate interior surfaces 127 of side members 126 together form a concave surface 138 that pushes against base members 118 of bristle bars 116 to firmly hold the bars in place, as shown.

In an example implementation, plate member 114 is located in a protective position above cushion member 110 and is preferably configured to provide gap 135 between the underside of plate member 114 and outer surface of cushion member 110, as shown. Gap 135 serves as a thermal break between the thermally-conductive metallic composition of plate member 114 and the elastomeric material forming cushion member 110. Among other advantages, gap 135 reduces thermal degradation of the cushion material.

Referring to the illustrations of FIG. 13 through FIG. 15, each bristle 112 takes the form of a slender peg projecting outwardly from the linear base member 118, as shown. In an example implementation, each bristle 112 may comprise a projecting length X2 of about 20.5 millimeters. In an example implementation the peg-like bristles 112 have a substantially cylindrical cross-section which tapers approaching the distal end, as shown. In an example implementation, each bristle 112 may comprise a proximal diameter D2 of about 2 millimeters and a distal diameter D3 of about 1 .12 millimeters. The distal ends of bristles 112 may comprise a smooth hemispherical shape to ensure user comfort during use.

Bristles 112 may be fabricated from a durable heat and chemical resistant material having a firm to rigid mechanical resiliency. Example materials include synthetic resins and similar polymeric materials such as nylon (polyamide), nylon blends, HDPE (high- density polyethylene), polyester PBT (polybutylene terephthalate), and the like. Bristles 112 and base member 118 may be molded as a single unit using well-known injection processes. The injection mold tools are preferably engineered to produce smooth surfaces that do not catch the hair or damage the scalp. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, other bristle arrangements, such as, for example, bristles having ball-point tips, metal pins, bristles infused with ion-releasing compounds, wooden bristles, bamboo bristles, etc., may suffice.

Applicant's use of thermal plate member 114 to thermally isolate and protect cushion member 110 expands the range of materials suitable in the construction of the resilient component. In an example implementation, cushion member 110 may be molded from a synthetic elastomer having approximately the same physical, chemical, and mechanical properties as natural rubber. Synthetic rubbers suitable for use in the fabrication of cushion member 110 may include styrene butadiene rubber (SBR), polybutadiene rubber (BR), acrylonitrile butadiene rubber (NBR), butyl rubber (MR), ethylene propylene diene rubber (EPDM), polychloroprene rubber (CR), and polyisoprene rubber (IR). It is noted that the use of other resilient materials, including natural rubber, is possible.

In an example implementation, the plurality of peg-like bristles 112 may be engaged within bristle support member 124 by inserting the bristle bars 116 through perforations 120 from the rear portion of cushion member 110. Perforations 120 within bristle support member 124 should be at least equal in size to the base diameter D2 of bristles 112. Tapering of the bristle shafts assists in frictionally retaining the bristle bars 116 within bristle support member 124. The enlarged base members 118 of bristle bars 116 prevent the bristles from being pulled through perforations 120 during use.

FIG. 16 shows an exploded view, illustrating an assembled bristle assembly 108 positioned for insertion into interior cavity 140 of brush head portion 104. In an example implementation, bristle assembly 108 is inserted into brush head portion 104 by slidably engaging recessed channels 136 on retaining side members 126 located along the sidewalls of interior cavity 140. Bristle assembly 108 is moved toward handle portion 106 until teeth 148 (see FIG. 1 1 ) and teeth 150 of locking retainer 146 are engaged.

Thermal plate member 114 is shown secured within brush head at three attachment points. FIG. 17 shows a partial perspective view, magnified for clarity, illustrating one the three attachment points. Each forward corner of plate member 114 is shown comprising a single locking barb 152 (at least embodying a slotted plate structure connect to the thermal plate and positioned beneath an uppermost surface of the thermal plate). Each locking barb 152 engages a respective one of the two locking-barb receivers 154 (at least embodying herein a slot corresponding to the slot of the slotted plate structure positioned beneath an uppermost surface of the thermal plate) located at the leading ends 141 of retention rails 142, as best shown in FIG. 18. FIG. 18 shows a partial perspective view, magnified for clarity, of one locking-barb receiver 154 of brush head portion 104. Locking-barb receiver 154 engages and captures the hook-like locking barb 152 of plate member 114. Such arrangement at least embodies herein at least one thermal-plate-to-brush-head-portion locking system. It is noted that the locking system securing thermal plate 114 in position and the locking system securing cushion member 110 in position assist to maintain gap 135 to avoid contact between thermal plate member 114 and cushion member 110. Such arrangement maintains the position of cushion member 110 and of plate member 114. It is further noted that FIG. 17 shows the slots of locking barb 152 and the slots of locking-barb-receiver 154 forming a joint wherein the planes of the slots of the locking barb 152 and that of the locking-barb-receiver 154 are in perpendicular planes. Such arrangement and connection is shown in FIGS. 16-17. It should be clear to those of skill in the art that if bristle assembly 108 and plate member 114 are to be removably connected from brush head portion 104, then the above described thermal-plate-to-brush-head-portion locking system and the cushion-member- to-brush-head-portion locking system are omitted.

The tongue-shaped arcuate rear portion 156 of plate member 114 is preferably secured by engagement of the arcuate rear portion 156 under the central outer wall 160 of brush head portion 104. See FIG. 3. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, other locking/securing arrangements, such as, for example, snap- together engagements, mechanical fasteners, spring lock devices, deformable captures, etc., may suffice. Central outer wall 160 extends upwardly and connects to side members 161 on opposing sides of the brush head. Central outer wall 160 has a semi-dome shaped structure that extends above cavity 140 and transitions into side members 161 forming connected with the sides of brush head portion 164, as shown in, for example, FIG. 16. The combination of central outer wall 160 and side members 161 forms a shrouding element that shrouds plate member 114, as shown in FIG. 3. Because plate member 114 is configured to be heated, the shrouding element provides protection to a user from contacting the hot plate member 114. Further, side members 161 of shrouding element provide additional gripping surfaces for a user. For example, a thumb and forefinger may be placed on side member 161 so that the user may manipulate the brush to style the hair without contacting hot plate member 114.

FIG, 19 through FIG. 21 illustrate another example implementation of brush-head portion 164 and handle 166 of hair brush 170 of hair brush system 100. Hair brush 170 is substantially similar to hair brush 102, thus, only the differences will be discussed below. In this regard, FIG. 19 shows a top view, illustrating brush head portion 164 and handle 166 of hair brush 170. FIG. 20 shows a sectional view, through the longitudinal section 20-20 of FIG. 19, illustrating various internal and external features of hair brush 170. FIG. 21 shows a side view, further illustrating various external features of hair brush 170

Within hair brush 170, the connective region between brush head portion 164 and handle 166 is shown with a textured pattern 172. Textured pattern 172 assists a user in firmly grasping the device during use. In an example implementation, textured pattern 172 comprises an arrangement of recesses arranged in a diamond-shaped pattern, as shown. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, other grip patterns, such as, for example, bumps, circumferential channels, circumferential ridges, friction enhancing- coatings, etc., may suffice.
