DETAILED DESCRIPTION OF EXEMPLARY IMPLEMENTATIONS

(23) The following detailed description is merely exemplary in nature and is not intended to limit the described embodiments or the application and uses of the described embodiments. As used herein, the word exemplary or illustrative means serving as an example, instance, or illustration. Any implementation described herein as exemplary or illustrative is not necessarily to be construed as preferred or advantageous over other implementations. All of the implementations described below are exemplary implementations provided to enable persons skilled in the art to make or use the embodiments of the disclosure and are not intended to limit the scope of the disclosure, which is defined by the claims. For purposes of description herein, the terms upper, lower, left, rear, right, front, vertical, horizontal, and derivatives thereof shall relate to the invention as oriented in FIG. 1. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description. It is also to be understood that the specific devices and processes illustrated in the attached drawings, and described in the following specification, are simply exemplary embodiments of the inventive concepts defined in the appended claims. Hence, specific dimensions and other physical characteristics relating to the embodiments disclosed herein are not to be considered as limiting, unless the claims expressly state otherwise.

(24) As is described in further detail below, the present invention is generally directed to a hand-supportable mobile device retaining apparatus having a portion configured for snugly receiving a finger of a user therein, and having an opposite portion configured for snugly receiving a peripheral edge portion of a mobile device therein, such that a user of the apparatus is able to controllably rotate the apparatus (and thus the retained mobile device) about the user's finger. In this manner, the apparatus enables a user to selectively angularly rotate the mobile device between a first angular orientation when the retained device is being used and a second angular orientation (e.g. against the back of a user's hand) when the retained device is not being used, thereby effectively freeing up the palm side of a user's hand as well as the fingers of the user's hand. In accordance with an alternative exemplary implementation, the hand supportable mobile device retaining apparatus may incorporate structural features enabling a user to angularly rotate a retained mobile device into a plurality of fixed/locked angular positions.

(25) Referring initially to FIGS. 1, 3 and 9, a hand-supportable mobile device retaining apparatus 100 is shown, in accordance with a first exemplary implementation of the invention. The apparatus preferably has a unitary main body comprised of a lower mobile device support portion 110, an upper mobile device support portion 130, and a finger-engaging portion 140. For the purpose of the present disclosure, use of the term proximal end herein is meant to refer generally to the finger-engaging portion 140 end of the main body, and the term distal end is meant to refer to the opposite end proximate to side 116 of lower device support portion 110.

(26) Lower support portion 110 is generally defined by opposite first and second sides, 112 and 114, respectively, distal end side 116, bottom, or lower, surface 118, and top, or upper, surface 120. As depicted, upper surface 120 is preferably corrugated to provide enhanced friction against a bottom surface of a mobile device 400 (FIG. 9) during use of the apparatus 100 to selectively retain the mobile device. As will be apparent to those skilled in the art, it is contemplated that any of a number of alternative surface contouring configurations may be implemented, in lieu of corrugation, to achieve the preferred enhanced frictional engagement. Furthermore, applicant contemplates the use of a friction-enhancing material layer disposed upon surface 120.

(27) Upper support portion 130 is generally defined by opposite first and second lateral sides, 132 and 134, respectively, distal end side 136, top/upper surface 138, and bottom/lower surface 139. As depicted, lower surface 139, opposing the upper surface 120 of lower device support portion 110, is also preferably corrugated to provide added friction between a peripheral top surface portion of a mobile device 400 (FIG. 9). Again, it is contemplated that any of a number of alternative surface contouring may be implemented, in lieu of corrugation, to achieve the preferred frictional engagement. Likewise, a friction-enhancing material may be disposed upon surface 139.

(28) Preferably, the aforementioned main body is constructed from a resilient moldable elastomeric material such as, for example, natural rubber, polybutadiene and polyurethane, to name just a few. In material science, resilience is the ability of a material to absorb energy when it is deformed elastically, and release that energy upon unloading. The upper device support portion 130 and the lower device support portion 110, spaced-apart from each other by mobile device insertion limiting vertical surface 122, are constructed such that they both have a cantilevered configuration (i.e. cantilevered off of finger-engaging portion 140). Significantly, the cantilevered configuration enables flexing of lower device support portion 110 and upper device support portion 130 away from each other upon insertion of a peripheral edge portion of a mobile device 400 (FIG. 9) therebetween. In this manner, the configuration is conducive to a tight frictional fit of the aforementioned mobile device peripheral edge portion between friction-enhanced surfaces 120 and 139, upon insertion of the mobile device peripheral edge portion therebetween.

(29) Finger-engaging, or finger-receiving, portion 140 has an upper portion 140a and a lower portion 140b, separated proximally by a proximal gap 164 of C-shaped finger-receiving channel 162, alternatively referred to herein as a finger-receiving opening. Generally, upper and lower portions, 140a and 140b, respectively, extend from a first side 142 and an opposite second side 144 of finger-receiving portion 140.

(30) Upper portion 140a is further bounded by upper side 148, proximal side 152, and finger-engaging surface 160. As depicted, upper portion 140a may (optionally) be further bounded by a distal side 146. As shown, distal side 146 may be in the form of a step-down feature from upper surface 148 of finger engaging upper portion 140a to upper surface 138 of upper device-supporting portion 130. Such a step-down feature may result where the lower device-supporting portion 110 and the upper device-supporting portion 130 are spaced-apart a relatively short distance I the thickness of finger-engaging portion 140 required to create finger-receiving, or finger-insertion, channel 162 defined by finger-engaging surface 160. Proximal side 152 and finger-engaging surface 160 are adjoined at upper edge 156.

(31) Lower portion 140b is further bounded by lower/bottom side 150, proximal side 154, and finger-engaging surface 160. Proximal side 154 and finger-engaging surface 160 are adjoined at a lower edge 158.

(32) Optionally, upper and lower edges, 156 and 158, respectively, of the C-shaped finger-receiving portion may be provided having a friction-enhancing composition, a friction-enhancing edge profile (e.g. a saw-toothed edge profile), and the like, for enabling the secure attachment of the apparatus to an object (e.g., a peripheral portion of a vehicle sun visor)as opposed to a human finger. Furthermore, such friction enhancement may be provided in the form of a separate edging layer disposed over the upper and lower edges, 156 and 158, respectively, of the C-shaped finger-receiving portion.

(33) Referring briefly to FIGS. 3 and 8, a C-shaped, resilient, spring-loaded, compression member 170 may be provided encapsulated within the main body (as shown in cross-section in FIG. 3) for urging respective upper and lower portions, 140a and 140b, toward one other. In this manner, C-shaped finger-receiving channel 162 is universally adapted for receiving a wide range of user finger sizes, in light of the combination of the flexible nature of the cantilevered structures of 140a and 140b, and the internal compressive force applied by compression member 170 urging the cantilevered structures toward one another. Referring now particularly to FIG. 8, C-shaped compression member 170 is generally defined by opposite first and second lateral ends, 172 and 174, respectively; lower and upper proximal ends, 176 and 178, respectively; exterior, or outer, surface 180; and interior surface 182. As depicted by the arrows in FIG. 8, lower and upper proximal ends, 176 and 178, respectively, are biased, or urged, toward one another by the inherent compressive force, F.sub.C, of compression member 170. As will be readily apparent to those skilled in the art, compression member 170 may be provided in the form of, for example, split seam compression tubing or a split seam compression sleeve. Such split compression tubes or sleeves are commercially available in a variety of metal and polymer materials. Furthermore, depending upon the mechanical characteristics of the chosen tubing material, dimension and the like, it is possible to control the resulting compressive force, F.sub.C, of compression member 170.

(34) Referring now again generally to FIGS. 1, 3, 8 and 9, finger-receiving channel 162 is further defined by channel surface 160. Optionally, surface 160 may further include a thin cushioning layer (not shown) of, for example, a silicone gel material or the like, for aiding user comfort during use. Furthermore, in a preferred implementation of the invention, an upper friction-enhancing edging 156 is provided separating upper portion front side 152 and finger-receiving channel surface 160, and a lower friction-enhancing edging 158 is provided separating lower portion front side 154 and finger-receiving channel surface 160. The upper and lower friction-enhancing edging, 156 and 158, respectively, are provided for enhancing attachment of the apparatus 100 to an object other than a finger. For example, applicant contemplates use of the apparatus 100 for hanging a mobile device from a sun visor in a motor vehicle. In that case, the C-shaped compression member 170 further functions to urge, or force, upper and lower friction-enhancing edging, 156 and 158, toward one another to effectively clamp the apparatus 100 to an edge portion of the sun visor. In that manner, the apparatus 100 can be used to hang a mobile device from the visor for hands-free viewing by a vehicle driver or passenger.

(35) Referring now briefly to FIG. 9, during use of the apparatus of the present invention, a mobile device 400 may be slidably inserted (in the direction of the arrows) into the mobile device retaining slot (previously described in great detail above) until the leading edge side 402 of the mobile device 400 abuts up against vertical wall surface 122, such that the mobile device 400 is securely frictionally retained therein by the frictional force of lower surface 139 of upper device-supporting portion 130 against mobile device upper peripheral edge portion 406, in combination with the frictional force of upper surface 120 of lower device-supporting portion 110 against a lower surface 408 of the mobile device. Although FIG. 9 illustrates this mobile device insertion process using the exemplary apparatus initially introduced in FIG. 1, it will be apparent that the same insertion process holds true for the exemplary apparatus 200 introduced in FIG. 2 (described in further detail below) and the exemplary apparatus 300 introduced in FIG. 4 (described in further detail below).

(36) Referring now primarily to FIG. 2, in accordance with an alternative exemplary implementation, a hand-supportable mobile device retaining apparatus, shown generally as reference numeral 200, is provided having a structure substantially similar to that described in accordance with the hand-supportable mobile device-retaining apparatus 100 of FIG. 1, with a primary distinction that apparatus 200 incorporates an O-shaped finger-receiving linear channel 262 in lieu of the C-shaped finger-receiving channel 162. Initially, it should be noted that elements/features 210, 212, 214, 216, 218, 220, 222, 230, 232, 234, 236, 238, 239 and 246, depicted in FIG. 2 corresponding directly to respective elements/features 110, 112, 114, 116, 118, 120, 122, 130, 132, 134, 136, 138, 139 and 146, depicted in FIG. 2. Accordingly, further description of these elements/features is identical to the description provided hereinabove with regard to apparatus 100.

(37) Apparatus 200 further includes finger-engaging portion 240 having an O-shaped linear channel 262 defined by contiguous o-shaped interior channel surface 260. Finger-engaging portion 240 is further defined by first lateral side 242, opposite second lateral side 244, upper side 248, lower side 250 and proximal side 252. Significantly, apparatus 200 does not incorporate an internal (i.e. encapsulated) compression member tantamount to the compression member 170 of apparatus 100. Although not shown in the accompanying figures, applicant contemplates that an O-shaped compressive tubing, or compressive sleeve, element may be provided inserted within finger-receiving channel 262 such that the compression tubing/sleeve is snugly received within the finger-receiving channel.

(38) Referring now primarily to FIGS. 4-7, a hand-supportable mobile device retaining apparatus 300 is shown, in accordance with a third exemplary implementation of the invention. Generally, the apparatus has a mobile device-retaining component 310 releasably attachable to a finger-retaining component 360. A significant feature of this exemplary implementation is that, during use, it enables a user to selectively angularly rotate the mobile device-retaining component 310 about the finger-retaining component 360, to a user-desired angular orientation and subsequently maintain the mobile device-engaging component at the desired angular orientationthereby maintaining a mobile device (not shown) at a user-desired angle.

(39) The mobile device-retaining component 310 has a structure that is similar in construction to the mobile device-engaging components 110, 210 of the prior exemplary implementation. Mobile device-retaining component 310 is generally defined by a lower mobile device-supporting portion 320, an upper mobile device-supporting portion 340 spaced-apart therefrom, and an adjoining thickened proximal end portion 350.

(40) Lower mobile device-supporting portion 320 is further defined by a first lateral side 322, and opposite second lateral side 324, a distal end side 326, a lower surface 328, and an upper mobile device-supporting surface 330.

(41) Upper mobile device-supporting portion 340 is further defined by a first lateral side 342, an opposite second lateral side 344, a distal end side 346, an upper surface 348, and an opposite lower mobile device-engaging surface 349.

(42) Upper surface 348 is adjoined to lower surface 328 via rounded thickened portion convex exterior surface 352. Lower mobile device-engaging surface 349 and upper device support surface 330 are adjoined by vertical device insertion-limiting surface 332. Together, lower surface 349, upper surface 330, and adjoining vertical surface 332 form a slot sized, shaped, and otherwise configured for snugly receiving a peripheral edge portion of a mobile device (not shown) being inserted into device-retaining component 310. A pair of protrusions 354 may be provided extending outwardly from opposite sides of thickened proximal end portion 350, each protrusion 354 having a series of flats 358 and an end 356. As described further below, the protrusions are sized, shaped, and otherwise configured for engagement with a complementary structure of finger-retaining component 360.

(43) Finger-retaining component 360 is preferably comprised of a unitary body incorporating a finger-engaging portion 370 on a proximal side thereof, in the form of a finger-receiving channel 372. Finger-engaging portion 370, defining finger-receiving channel 372, may have a structure substantially similar to finger engaging portions 140 and 240, defining corresponding finger-receiving channels 162 and 262, of apparatus 100 and 200, respectively.

(44) A pair of identical, spaced-apart, tangs 363 is provided extending distally away from finger-retaining component 360, with each one of the pair of tangs extending from opposite ends thereof. Each tang 363 is provided having an aperture 364 extending therethrough. Preferably, each aperture is defined by a contiguous series of flats 368 corresponding to the respective series of flats 358 on the exterior surface of protrusions 354. As depicted by the dotted arrowed line in FIG. 4, during assembly of the finger-retaining component 360 to the device-retaining component 310, the opposing protrusions 354, or nubs, are inserted through the corresponding apertures 364 extending through tangs 363. Along its most distal side, finger-retaining component 360 has a concave surface 362 conforming to smooth rounded exterior convex surface 352 of thickened proximal end portion 350 of device-engaging component 310. This enables rotation of device-retaining component 310 about finger-retaining component 360 in an unimpeded manner.

(45) As best depicted in FIG. 5, when finger-retaining component 360 is fully assembled to device engaging component 310, protrusions 354 fit snugly within apertures 364 of finger-retaining component tangs 363, such that protrusion flats 358 are directly aligned with and abut corresponding tang aperture flats 368. Due to the resilient, temporarily deformable composition of the protrusion, the edges separating adjacent flats 358 of protrusions 354 are able to temporarily deform when device-retaining component 310 is angularly rotated about finger-retaining component 360, until each series of flats are realigned with one another.

(46) Referring now particularly to FIGS. 6 and 7, angular adjustment of the mobile device-retaining component about the finger-retaining component will now be briefly described, with reference to the particular exemplary structure described hereinabove.

(47) As shown in FIG. 6, device-retaining component 310 is shown angularly-offset 180-degrees from finger-retaining component 360. Obviously, during use a user's finger (e.g. the index finger of a user's left hand) would be inserted into finger-receiving channel 372 of finger-engaging portion 370 of finger-retaining component 360. As a result of the compression of the finger-receiving channel surface against the user's finger, due to the unique compressive construction previously described in great detail hereinabove with respect to the first implementation of the hand-supportable mobile device retaining apparatus 100 (in conjunction with the depictions in FIGS. 1, 3 and 8), the finger-engaging portion 370 is tightly engaged against the user's finger, preventing rotation of the channel 372 about the finger due to inadvertent slippage. Likewise, where the apparatus 300 is being used to secure a mobile device to an object (e.g. a vehicle sun visor) the unique construction also prevents such undesirable rotation.

(48) Through application of a relatively nominal force a user of the apparatus 300 is able to rotate the finger-retaining component from a first position 360 (FIG. 6) to a second, angularly-offset, position 360 (FIG. 7) as desired. As will be apparent to those skilled in the art, the particular mechanism provided to illustrate the locking angular rotation functionality was merely an example of one such configuration enabling such functionality; however, the invention is not intended to be so limiting. Likewise, with regard to the particular locking angular rotation mechanism used to illustrate this functionality, it is contemplated that in lieu of having protrusions 354 extending outwardly from the mobile device-retaining component 310 cooperatively engaging corresponding apertures 364 extending through the tangs 363 of the finger-retaining component 360, protrusions 354 could have been provided extending inwardly from the tangs (i.e. in place of the apertures 364) for cooperatively engaging corresponding apertures/cavities extending into the inwardly into the proximal thickened end portions 350 in place of the protrusions 358.

(49) Referring now generally to FIGS. 10-19, a handheld mobile device support apparatus 500, 700 is shown in accordance with a further embodiment of the present invention. Referring initially to FIGS. 10, 10A, 12, and 13-15, a handheld mobile device support apparatus 500 is shown in accordance with at some implementations of the present invention. Preferably, the apparatus 500 is provided having a unitary, or one-piece, molded structure including a support panel 502 and a universal finger-engaging cradle 520. Support panel 502 and finger-engaging cradle 520 are preferably molded from a relatively rigid polymer such as, for example, high-density polyethylene (HDPE), polypropylene (PP) and Polystyrene (PS), to name just a few.

(50) Support panel 502 is generally defined by a front surface 504 and an opposite rear surface 506 separated by a contiguous perimeter (508, 510, 512, 514). The contiguous perimeter may include first and second lateral edges, 508 and 510, respectively, and upper and lower edges, 512 and 514, respectively. Upper edge 512 may be referred to herein by alternative terms, such as top edge, upper end, and distal end of support panel 502. Likewise, lower edge 514 may be referred to herein by alternative terms, such as bottom edge, lower end, and proximal end of support panel 502.

(51) A tacky gel pad 516 (alternatively referred to herein as gel pad layer and adhesion pad) is provided disposed upon an area of front surface 504 of support panel 502. Significantly, tacky gel pad layer 516 is formed from a material imparting a permanent tackiness, or permanent stickiness, to front exposed surface 517. In a preferred implementation, adhesion pad 516 is formed from a polyurethane gel composition. Unlike thermoplastic elastomers (TPE) or polyvinylchloride (PVC) based adhesion pad products, polyurethane gels do not have to contain processing oil, plasticizer, or other low-molecular-weight (liquid) materials, which could leach and dirty the contact surface; potentially, degrading the pad's adhesive characteristics. Acrylate and other polymers compounded with so-called tackifiers are other commonly used to create sticky, or tacky, surfaces; however, they are not preferred for use with the present invention because they do not impart a permanent tack to the exposed front surface 517 of the gel pad. To the contrary, the tackiness, or stickiness, associated with these materials continuously decreases with use. Thus, continually adhering, and then detaching, the rear side of a mobile phone housing to such a surface, even a few times, would significantly degrade the tackiness in short order. As should be apparent to those skilled in the relevant arts, non-polyurethane gel pad compositions could be employed, without departing from the intended scope of the present invention, as long as such alternative compositions impart the desired adhesive characteristics. That is, as long as the chosen composition provides a substantially permanent degree of adhesive force between the gel pad exposed surface 517 and the rear surface of the adhered mobile device when successively used over a period of time, such that the adhesive force is sufficient to prevent inadvertent detachment of the mobile device from the gel pad during use. For example, gel pad 516 may be formulated from silicone elastomers, or any other available chemical composition, imparting the required permanent adhesive force to the attached mobile device.

(52) One example of a preferred polyurethane resin for forming gel pad 516 is GK-22 Polyurethane Gel manufactured by Tandem Products, Inc. d/b/a Northstar Polymers, LLC of Minneapolis, Minn. This polyurethane gel composition is a 2-part thermoset material. The molecular weight of the reaction products is controlled to yield a polymer film, which exhibits a state between highly viscous liquid and solid at room temperature. Significantly, this makes the polymer film permanently tacky without leaching out low-molecular-weight liquid. This is ideal material for pressure sensitive adhesive (PSA) applications such as the present application, where permanent tackiness without residue is important. The material may be cured at room temperature. With a simple casting process, it can be laminated and adhere permanently to high-surface-energy plastic films (not shown in the drawings) such that the laminated polyurethane gel can be cut to the desired shape, and attached to other plastic substrates (i.e. such as front surface 504 of front panel 502) using a glue or other chemical adhesive interposed between the plastic film and the front surface 504.

(53) Accordingly, although not shown in the accompanying drawing figures, it will be understood to those skilled in the related arts that tacky gel pad 516 may have a structure that includes a relative thick layer of polyurethane gel, for example, disposed upon an underlying plastic film base. Accordingly, the plastic film base (not shown) of the tacky gel pad 516 may be easily directly adhered to front surface 504 of support panel 502 using a glue or other appropriate chemical adhesive. Most mobile smartphones have a weight within a range of about 4 ounces to 10 ounces. Therefore, it is preferable that the exposed surface 517 of gel pad 516 imparts an adhesive force to the rear surface 408 of a temporarily adhered mobile device 400 adequate to prevent the adhered mobile device from unsticking, or detaching, from the gel pad surface regardless of the orientation of the support panel 502. That is, the adhesive bond between the device 400 and the gel pad surface 517 should be sufficient to overcome the maximum downward force of the weight of the carried mobile device.

(54) Briefly, as best shown in FIG. 14, finger-engaging cradle 520 may be in the form of a semi-cylindrical body having an interior, concave finger-engaging surface 522, and an opposite exterior, convex surface 524 adjoining the finger-engaging cradle 520 with the lower edge 514 of the support panel 502. The finger-engaging cradle 520 (alternatively referred to herein as a finger-engaging cradle and a finger cradle) is further defined by a pair of forward and rearward lower edges, 526a and 526b, respectfully, and opposite first and second lateral edges, 528 and 530, respectively. For purposes further described herein, first and second strap-receiving lateral slots, 532a and 532b, respectively, are provided extending through the semi-cylindrical body of finger cradle 520.

(55) Referring now primarily to FIG. 11, an adjustable finger retention strap length 540 is preferably provided for maintaining a tight engagement of a user's finger against concave finger contact surface 522 of finger cradle 520 during use. The strap length 540 may be constructed from a non-stretchable, non-resilient flexible material such as Nylon. Alternatively, the strap length 540 may be constructed from a stretchable, resilient flexible material such as rubber, silicone, and the like.

(56) Strap length 540 may include a thickened strap end 544 and an opposite free end 546. Furthermore, an exterior surface 542a of strap length 540 may have disposed thereon a first half 550 of a hook-and-loop attachment system proximate to the free end 546 of strap, and a second half 552 of the hook-and-loop attachment system spaced inwardly from the first half 550, toward an intermediate strap length location. During attachment of the apparatus 500 to a user's finger 606 (see FIG. 18) free strap end 546 may be fed through first strap-receiving slot 526a of finger support cradle 520, around the user's finger, and through second strap-receiving slot 526b, to form a strap loop 542. Subsequently, the free strap end 546 may be pulled taut and folded back upon itself, or tightened, to firmly sandwich the user's finger between interior strap surface 542b and concave finger contact surface 522 of finger cradle 520. The thickened strap end 544 is provided having a thickness greater than the width of first strap-receiving slot 526a to prevent the thickened strap end from being inadvertently pulled therethrough. Finally, the first half 550 of the hook-and-loop system may be releasably secured to the respective second half 552 of the hook-and-loop system to tightly secure the apparatus 500 to a user's finger, such that the apparatus 500 and carried mobile device 400 are secured and the user can selectively rotate the apparatus (and attached mobile device) about the central axis of the user's finger, between a non-use position/orientation, wherein the user's hands are kept free for other uses, and an in-use position/orientation, wherein the mobile device is oriented to enable the user to interact via the user's thumbs with the mobile device touchscreen display.

(57) Furthermore, support panel 502 may incorporate a plurality of auxiliary mobile device support clips 570 for complementing, or augmenting, the adhesive support rendered by gel pad 516 to mobile device 400. Preferably, the mobile device support clips 570 are integral with support panel 502. That is, it is preferred that the support clips 570 are provided as molded features of the apparatus 500. As will be apparent to those skilled in the art, while not preferred, the support clips 570 may optionally be provided as separate components attached about the periphery of the support panel 502. Furthermore, although the support clips 570 are shown located at particular positions about the support panel periphery any number of clips may be provided at any corresponding peripheral locations desired. Likewise, in addition to clips 570, or in lieu thereof, corner ears (not shown) defining receiving slots may be integrated overhanging corner portions of support panel front surface 504 for seating corners of a corresponding portable mobile device therein.

(58) Referring now particularly to FIG. 19, finger-supporting cradle 520 (shown with adjustable finger retention strap length 540 removed for convenience) may be used for auxiliary applications, such as attaching the apparatus 500 to a structural surface, such as cylindrical support member 650. For instance, the finger support cradle 520 may be employed (in conjunction with adjustable finger retention strap length 540) to temporarily fasten the apparatus to handlebars of a bicycle, a vehicle steering wheel, or any other cylindrical structure.

(59) Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalents.
