Technical Field

[0001] This invention generally relates to a sole accessory for cycling shoes. More specifically, this invention relates to a sole accessory for cycling shoes configured to use a skid plate. Background Technology

[0002] Generally, most cycling shoes have an upper and a sole. The upper is stitched or adhesively bonded to the sole to form an internal foot receiving space for securely receiving the foot. The upper is typically formed of one or more flexible materials, such as textiles, leather, and / or synthetic leather, stitched or adhesively bonded together. The upper may also include rigid reinforcements as needed and / or desired. The upper defines an ankle opening for inserting the wearer's foot into the internal foot receiving space and for removing the wearer's foot from the internal foot receiving space. Additionally, the upper may include laces or other closures to more securely hold the cycling shoe to the wearer's foot within the internal foot receiving space. The sole may be a single layer made of a suitable material or may be made of several layers of different materials. In the case of many athletic shoes, the sole typically has an insole, a midsole, and an outsole. The insole defines the bottom surface of the internal foot receiving space. The insole may be a thin, compressible member that improves shoe comfort. The midsole is typically attached to the lower edge of the upper. The midsole is typically the middle layer of the sole. The outsole is usually attached to the lower surface of the midsole and forms the ground contact portion of the shoe. Some cycling shoes are equipped with skid plates, which are used to attach the skid plate to the bottom surface of the shoe. In some cases, cycling shoes have pontoons in the sole to protect the skid plate and prevent it from impacting the ground. Summary of the Invention

[0090] Selected embodiments of the invention will now be explained and described with reference to the accompanying drawings. It will be apparent to those skilled in the art of human-powered vehicles (e.g., bicycles) that, based on this disclosure, the following description of the embodiments is for illustrative purposes only and is not intended to limit the invention as defined by the appended claims and their equivalents.

[0091] First refer to Figure 1 and Figure 2This example illustrates a cycling shoe 10 according to a first embodiment of the present invention. A sole attachment 12 is provided for the cycling shoe 10. The cycling shoe 10 is the right shoe in a pair of symmetrical shoes, with the left cycling shoe omitted. The left cycling shoe is identical to the right cycling shoe 10, except that it is a mirror image of the right cycling shoe 10. Therefore, the description of the cycling shoe 10 also applies to the left shoe. Therefore, only one of the cycling shoes (the right cycling shoe 10) will be described. The cycling shoe 10 is particularly suitable for cycling or other human-powered vehicles with pedals.

[0092] As should be understood from the accompanying drawings and descriptions herein, the terms "inner side" and "middle side" refer to the right side of a cycling shoe for the left foot and the left side of a cycling shoe for the right foot. In other words, the inner side or inner side is the side of the cycling shoe facing the wearer's other foot. Similarly, the terms "outer side" and "outer side" refer to the left side of a cycling shoe for the left foot and the right side of a cycling shoe for the right foot. The outer side or outer side is the side of the cycling shoe facing away from the other foot. Furthermore, the terms "inner side" and "middle side" are used interchangeably with respect to this disclosure. Similarly, the terms "outer side" and "outer side" are used interchangeably with respect to the description of this disclosure. Furthermore, the term "outer instep side" refers to the left side of the cycling shoe in the instep area of ​​the left foot and the right side of the cycling shoe in the instep area of ​​the right foot. Similarly, the term "inner instep side" refers to the right side of the cycling shoe in the instep area of ​​the left foot and the left side of the cycling shoe in the instep area of ​​the right foot.

[0093] Basically, such as Figure 1 and Figure 2 As seen in the illustration, the cycling shoe 10 includes a sole 14 and an upper 16. The sole 14 is attached to the upper 16. In a first embodiment, the cycling shoe 10 further includes a sole attachment 12. The sole 14 supports the upper 16. For example, the sole 14 can be fixedly attached to the upper 16 in a conventional manner, such as by stitching, gluing, and / or embedding portions of the upper 16 within the sole 14. Thus, the upper 16 and the sole 14 are integrated together. In this way, the sole 14 and the upper 16 form the cycling shoe 10. In the illustrated embodiment, the sole 14 is particularly useful for cycling. The cycling shoe 10 has a longitudinal direction L and a lateral or width direction W. The longitudinal direction L extends longitudinally from the toe end of the cycling shoe 10 to the heel end. The width direction W is perpendicular to the longitudinal direction L. The sole 14 has a longitudinal center plane CP parallel to the longitudinal direction L. Figure 2 As seen in the image, the longitudinal center plane CP divides the toe end of the cycling shoe 10 in two and the heel end of the cycling shoe 10 in two.

[0094] Here, the upper 16 is a low-top style upper. However, the upper 16 is not limited to a low-top style, but can be any style. The upper 16 is made of any suitable natural or polymeric material. The upper 16 can be formed of an expandable or non-expandable material. For example, the upper 16 can be made of leather, nylon mesh, and / or any other material used in conventional uppers. Alternatively, the upper 16 can be made of a stretchable material or stretchable fabric that has the ability to stretch and elastically return to its initial unstretched state. For example, the stretchable material can be partially made of elastic fibers (such as Lycra, Spandex, or other elastic fibers), and / or can be a knitted fabric stretched due to a series of interlocking loops formed during the production of the upper 16. Here, the upper 16 is made of mesh thermoplastic polyurethane and synthetic leather material.

[0095] like Figure 2 As seen in the illustration, the upper 16 includes a first lateral side 16a and a second lateral side 16b. The upper 16 further includes a tongue 16c located between the first lateral side 16a and the second lateral side 16b. The upper 16 includes a foot receiving opening 16d formed between the first lateral side 16a and the second lateral side 16b. Here, the upper 16 further includes a fastening structure 18 for securing the cycling shoe 10 to the wearer's foot. The fastening structure 18 may also be referred to as a lacing structure or a shoe closure. The fastening structure 18 may, for example, include at least one shoe tightener 18A and at least one lace or cord 18B associated with said at least one shoe tightener 18A. In the illustrated embodiment, the fastening structure 18 includes a pair of shoe tighteners 18A. Each of the shoe tighteners 18A includes a cord 18B. Here, the shoe tightener 18A is a roll-type closure that pulls and releases the cord 18B to adjust the tension of the cord 18B. One of the shoe tightening members 18A is disposed on the first lateral side 16a, and the other of the shoe tightening members 18A is disposed on the strap 18C. A cord 18B of the shoe tightening member 18A on the first lateral side 16a extends through the tongue 16c and is connected between a shoelace guide 18D on the first lateral side 16a and a pair of shoelace guides 18E on the second lateral side 16b. The cord 18B of the shoe tightening member 18A on the strap 18C is connected to the shoelace guide on the first lateral side 16a.

[0096] Of course, other types of fastening structures can be used. For example, fastening structure 18 can simply be a shoelace connecting the first lateral side 16a and the second lateral side 16b. Furthermore, for example, the upper 16 can include one or more fastening strips with hook-and-loop fasteners having a fabric hook-and-loop fastening material. Since the fastening structures used to secure the shoe to the wearer's foot are conventional and well-known structures, a detailed description of the fastening structures is omitted for brevity. Because the invention is applicable to a wide variety of shoe styles, designs, and constructions, the depicted embodiments illustrate basic shoe designs made of several textile-based materials that are stitched or sewn together to form the depicted shape. However, the invention is not limited to the depicted shape, as will be understood from the following description of the invention.

[0097] Preferably, the cycling shoe 10 further includes an inner insole disposed inside the upper 16. The inner insole at least partially covers the upper surface or inner surface 14a of the sole 14. The inner insole is removably disposed on the sole 14. In other words, preferably, the inner insole is not attached to the sole 14. Instead, the inner insole is simply placed on top of the sole 14. The inner insole may also be referred to as the insole. The inner insole may be made of conventional materials commonly used for insoles of cycling shoes. For example, here, the inner insole comprises a layer of foam material. The inner insole may also be made of several layers of different materials.

[0098] Here, as Figure 1 and Figure 2 As seen in the image, the sole 14 further includes an outsole 20 disposed on the bottom surface 14b of the sole 14. The outsole 20 preferably comprises a rubber material. The rubber material of the outsole 20 can be natural rubber, synthetic rubber, or a mixture of natural and synthetic rubber. Here, the outsole 20 comprises an elastic polymer material, such as synthetic rubber or polyurethane (e.g., thermoplastic polyurethane). The outsole 20 can be formed by injection molding. The outsole 20 forms the ground contact surface of the sole 14. If desired and / or expected, the outsole 20 may include a tread to provide adhesion to the sole 14 during use. The outsole 20 is attached to the sole 14 by using an adhesive bond or by bonding via an overmolding process. The outsole 20 includes a plurality of sole blocks 20a disposed on the bottom surface 14b of the sole 14. Here, three sole blocks 20a are disposed in the forefoot area of ​​the shoe 10 and surround the sole attachment 12.

[0099] refer to Figures 2 to 7The anti-slip plate 22 is attached to the bottom surface 14b of the sole 14. The anti-slip plate 22 can also be referred to as a bicycle pedal anti-slip plate or a riding anti-slip plate. The anti-slip plate 22 can be attached to the sole 14 by a pair of fasteners 24 and an anti-slip plate nut 26. Here, the sole 14 has a pair of through openings 14c for receiving the fasteners 24 passing through them. Preferably, the openings 14c are elongated slots extending in a direction generally parallel to the longitudinal direction L. Furthermore, the sole 14 has a sole groove 14d for receiving the anti-slip plate nut 26. Washers or gaskets 28 can be provided for the fasteners 24 in a conventional manner. Here, the anti-slip plate 22 is a double-bolt anti-slip plate attached to the sole 14 using two bolts (i.e., fasteners 24). The anti-slip plate 22 includes a mounting part 30, a first pedal engagement part 32, and a second pedal engagement part 34. The mounting part 30, the first pedal engagement part 32, and the second pedal engagement part 34 are integrally formed as a single part. Therefore, the anti-slip plate 22 is a one-piece component.

[0100] The mounting part 30 of the anti-slip plate 22 is configured to be attached to the bottom surface 14b of the sole 14 by screwing a fastener 24 into the paired threaded holes 26a of the anti-slip plate nut 26. Specifically, in the first embodiment, the mounting part 30 of the anti-slip plate 22 includes a through opening 36 for receiving the fastener 24 passing through it. Here, the through opening 36 is an elongated slot that extends in a direction generally parallel to the width direction W of the sole 14 when the anti-slip plate 22 is in the mounted state (i.e., the anti-slip plate 22 is attached to the sole 14). As described below, in the mounted state where the sole attachment 12 and the anti-slip plate 22 are attached to the sole 14 by the fastener 24 and the anti-slip plate nut 26, the sole attachment 12 is disposed between the bottom surface 14b of the sole 14 and the mounting part 30 of the anti-slip plate 22. Therefore, the anti-slip plate 22 and the sole attachment 12 are configured to be attached to the bottom surface 14b of the sole 14 by screwing the fastener 24 into the threaded hole 26a of the anti-slip plate nut 26.

[0101] like Figure 5 and Figure 7 As seen in the image, the mounting part 30 of the anti-slip plate 22 further includes a plurality of protrusions 38 for engaging the sole attachment 12 in the mounted state. A first pedal engagement part 32 and a second pedal engagement part 34 extend from the mounting part 30 in opposite directions. The first pedal engagement part 32 and the second pedal engagement part 34 are configured to engage clipless or step-in pedals in a conventional manner.

[0102] The anti-slip plate 22, anti-slip plate nut 26, and washer or shim 28 are made of rigid materials, such as metal. Anti-slip plates, anti-slip plate nuts, and washers, such as anti-slip plate 22, anti-slip plate nut 26, and washer or shim 28, are known in the field of human-powered vehicles. Therefore, anti-slip plate 22, anti-slip plate nut 26, and washer or shim 28 will not be discussed in detail herein.

[0103] Still referencing Figures 2 to 7 As mentioned above, the sole attachment 12 is connected to the bottom surface 14b of the sole 14 via fasteners 24 and anti-slip nut 26. In this way, the sole attachment 12 is detachably and reattached to the bottom surface 14b of the sole 14. In the installed state, the sole attachment 12 is positioned in direct contact with the bottom surface 14b of the sole 14, and the anti-slip plate 22 is located on the opposite side of the sole attachment 12. In this way, in the installed state, the sole attachment 12 is positioned between the sole 14 and the anti-slip plate 22.

[0104] The sole accessory 12 basically includes a first block 40, a second block 42, and a bridging member 44. The bridging member 44 connects the first block 40 and the second block 42. In the installed state, the anti-slip plate 22 is positioned between the first block 40 and the second block 42 in the width direction W relative to the sole 14. Furthermore, in the installed state, the first block 40 is positioned on the outer side of the anti-slip plate 22 in the width direction W relative to the sole 14, and the second block 42 is positioned on the inner side of the anti-slip plate 22 in the width direction W relative to the sole 14.

[0105] Here, as Figure 6 As seen in the diagram, the first block 40 includes a first anti-slip plate receiving portion 46. The first anti-slip plate receiving portion 46 is configured to receive at least a portion of a first portion 30a of the anti-slip plate 22. Specifically, the first portion 30a of the anti-slip plate 22 corresponds to a first lateral portion of the mounting member 30. The first anti-slip plate receiving portion 46 defines a first concave surface 46a that follows the contour of the peripheral surface of the first portion 30a of the mounting member 30 of the anti-slip plate 22. In other words, the first concave surface 46a is configured to fit into the first portion 30a of the anti-slip plate 22. The second block 42 includes a second anti-slip plate receiving portion 48. The second anti-slip plate receiving portion 48 is configured to receive at least a portion of a second portion 30b of the anti-slip plate 22. Specifically, the second portion 30b of the anti-slip plate 22 corresponds to a second lateral portion of the mounting member 30. The second anti-slip plate receiving portion 48 defines a second concave surface 48a, which follows the contour of the peripheral surface of the second portion 30b of the mounting part 30 of the anti-slip plate 22. In other words, the second concave surface 48a is configured to fit into the second portion 30b of the anti-slip plate 22.

[0106] Now for reference Figures 8 to 18 The sole attachment 12 will now be described in more detail. In the first embodiment, the first block 40 and the second block 42 are disposed at opposite ends of the bridging member 44. Here, the first block 40 and the second block 42 are mirror images of each other with respect to a plane P1 parallel to the longitudinal center plane CP of the sole 14, as shown below. Figure 8 As seen in the diagram. As described below, the first block 40 and the second block 42 are connected to the end of the bridging member 44 via an overmolding process. In this way, both the first block 40 and the second block 42 are integrated with the bridging member 44.

[0107] Preferably, each of the first block 40 and the second block 42 comprises an elastomeric material. For example, the elastomeric material comprises a rubber material. Alternatively, for example, the elastomeric material comprises a resin material. Preferably, the resin material comprises a polyamide material. Furthermore, the elastomeric material of the first block 40 and the second block 42 may comprise a combination of rubber and resin materials. Additionally, although the first block 40 and the second block 42 are made of the same material, it is apparent to the present invention that the first block 40 may be made of a first material, and the second block 42 may be made of a second material different from the first material. Preferably, the bridging member 44 comprises a metallic material. For example, the metallic material is selected from the group consisting of iron, aluminum, titanium, and stainless steel. In the first embodiment, the first block 40 and the second block 42 are injection molded onto the ends of the bridging member 44.

[0108] refer to Figures 7 to 12 The first block 40 includes a first surface 50 facing the sole and a first surface 52 facing the ground. For example... Figure 7 As seen in the image, the first ground-facing surface 52 is opposite the first sole-facing surface 50 in the thickness direction T1 of the cycling shoe 10. The first block 40 further includes a first peripheral side surface 54. The first peripheral side surface 54 is located between the first sole-facing surface 50 and the first ground-facing surface 52. The first block 40 further includes a first inclined surface 56, which is disposed on the side of the first block 40 opposite to the sole 14 of the cycling shoe 10.

[0109] refer to Figure 13 The first inclined surface 56 has a first slope S1. The first slope S1 is a measure of the steepness of the first inclined surface 56 relative to the first ground-facing surface 52. Therefore, the first inclined surface 56 forms a first tilt angle θ1 relative to the first ground-facing surface 52. Here, for example, the first tilt angle θ1 is approximately thirty degrees plus or minus ten degrees (30° ± 10°).

[0110] refer to Figure 14The second block 42 includes a second surface 60 facing the sole and a second surface 62 facing the ground. For example... Figure 7 As seen in the image, the second ground-facing surface 62 is opposite the second sole-facing surface 60 in the shoe thickness direction T1. The second block 42 further includes a second peripheral side surface 64. The second peripheral side surface 64 is located between the second sole-facing surface 60 and the second ground-facing surface 62. The second block 42 includes a second inclined surface 66. The second inclined surface 66 is disposed on the side of the second block 42 facing away from the sole 14. The second inclined surface 66 has a second slope S2. The second slope S2 is a measure of the steepness of the second inclined surface 66 relative to the second ground-facing surface 62. Therefore, the second inclined surface 66 forms a second slope angle θ2 relative to the second ground-facing surface 62. In the first embodiment, the second slope S2 is equal to the first slope S1. Therefore, for example, the second slope angle θ2 is approximately thirty degrees plus or minus ten degrees (30° ± 10°).

[0111] Return to reference Figures 7 to 12 The bridging member 44 has a first bridging surface 70 and a second bridging surface 72. The first bridging surface 70 is configured to contact the anti-slip plate 22. The second bridging surface 72 is configured to contact the sole 14 of the cycling shoe 10. The second bridging surface 72 is disposed on the side of the bridging member 44 opposite to the first bridging surface 70 in the bridging thickness direction T2. ​​The bridging member 44 is disposed closer to the first surface 50 and the second surface 60 facing the sole in the bridging thickness direction T1 than to the first surface 52 and the second surface 62 facing the ground.

[0112] refer to Figures 7 to 10 The bridging member 44 has a first end portion 74 and a second end portion 76. The first end portion 74 is connected to a first block 40. The second end portion 76 is connected to a second block 42. The bridging member 44 has an intermediate portion 78 disposed between the first end portion 74 and the second end portion 76. The intermediate portion 78 has a fastener receiving opening 78a. The fastener receiving opening 78a is an elongated opening configured to receive two fasteners 24 passing through it. A first bridging member surface 70 and a second bridging member surface 72 are disposed on the intermediate portion 78. Here, the first bridging member surface 70 of the intermediate portion 78 has at least one rib 80. Here, the at least one rib 80 is an annular flange. The annular flange or rib 80 surrounds the fastener receiving opening 78a. The annular flange or rib 80 is sized to fit into the through opening 36 of the anti-slip plate 22. Preferably, the annular flange or rib 80 is fitted tightly into the through opening 36 of the anti-slip plate 22 to minimize the relative movement of the sole attachment 12 relative to the anti-slip plate 22 during the attachment of the sole attachment 12 and the anti-slip plate 22 to the sole 14.

[0113] refer to Figure 15 and Figure 16 The first bridging component surface 70 has at least one groove 70a. The second bridging component surface 72 has at least one protrusion 72a. The at least one groove 70a and the at least one protrusion 72a are aligned in the bridging component thickness direction T2. ​​Here, the at least one groove 70a comprises a plurality of grooves 70a, and the at least one protrusion 72a comprises a plurality of protrusions 72a. The groove 70a surrounds the fastener receiving opening 78a. Similarly, the protrusion 72a surrounds the fastener receiving opening 78a. The groove 70a and the protrusion 72a are aligned in the bridging component thickness direction T2. ​​In this way, the groove 70a and the protrusion 72a are formed by pressing the intermediate portion 78 and deforming it so that the groove 70a is formed on the first bridging component surface 70, resulting in the protrusion 72a being formed on the second bridging component surface 72.

[0114] refer to Figure 17 and Figure 18 Here, the first end portion 74 is embedded in the first block 40. For example, the first block 40 is connected to the first end portion 74 of the bridge 44 by overmolding the first block 40 onto the first end portion 74. Similarly, the second end portion 76 is embedded in the second block 42. For example, the second block 42 is attached to the second end portion 76 of the bridge 44 by overmolding the second block 42 onto the second end portion 76. The first end portion 74 includes at least one first hole 74a occupied by the first block 40. Here, the first end portion 74 includes a plurality of (four) first holes 74a. The first holes 74a are occupied by the first block 40. In other words, the material of the first block 40 is disposed in each first hole 74a. The first end portion 74 includes at least one first rib 74b embedded in the first block 40. Here, the first end portion 74 includes a plurality of (two) first ribs 74b.

The shoe sole attachment 112 is configured for use with the cycling shoe 10 and skid plate 22 of the first embodiment. Of course, the shoe sole attachment 112 can be configured for use with other cycling shoes and skid plates. In the second embodiment, the shoe sole attachment 112 essentially includes a first block 140, a second block 142, and a bridging member 144. The first block 140 is identical to the first block 40 of the first embodiment. Furthermore, the bridging member 144 is identical to the bridging member 44 of the first embodiment. However, as described below, the second block 142 has been modified from the second block 42 of the first embodiment. Given the similarity between the first and second embodiments, for the sake of brevity, descriptions of parts identical to those in the first embodiment in the second embodiment can be omitted.

[0116] Here, the first block 140 includes a first anti-slip plate receiving portion 146, and the second block 142 includes a second anti-slip plate receiving portion 148. The first block 140 further includes a first surface 150 facing the sole, a first surface 152 facing the ground, a first peripheral side surface 154, and a first inclined surface 156. The first inclined surface 156 has a first slope S1. The first slope S1 is a measure of the steepness of the first inclined surface 156 relative to the first surface 152 facing the ground. Therefore, the first inclined surface 156 forms a first tilt angle θ1 relative to the first surface 152 facing the ground. On the other hand, the second block 142 further includes a second surface 160 facing the sole, a second surface 162 facing the ground, a second peripheral side surface 164, and a second inclined surface 166. The second inclined surface 166 has a second slope S2. The second slope S2 is a measure of the steepness of the second inclined surface 166 relative to the second surface 162 facing the ground. The second slope S2 is different from the first slope S1. Specifically, the second inclination S2 is greater than the first inclination S1. For example, the first inclination angle θ1 is approximately thirty degrees plus or minus ten degrees (30° ± 10°), while the second inclination angle θ2 is approximately forty degrees plus or minus ten degrees (40° ± 10°). In any case, in the second embodiment, the second inclination S2 is different from the first inclination S1. Therefore, in the second embodiment, the second inclination angle θ2 is different from the first inclination angle θ1.
