The bicycle cleat cover device is configured to be releasably secured to a bicycle cleat, wherein the bicycle cleat has an aperture sized and configured to receive a clipless pedal. The removable bicycle cleat cover device serves to inhibit debris from entering the central opening of the bicycle cleat when the bicycle cleat is disengaged from a pedal and the user is walking about on the ground.

Description

FIELD OF THE INVENTION

The present invention relates generally to bicycle cleat assemblies configured for releasable securement to clipless bicycle pedals, and, more particularly, to an aperture cover configured to be releasably retained within a central opening of a bicycle cleat assembly when a user's shoe is disengaged from a clipless bicycle pedal.

BACKGROUND OF THE INVENTION

Bicycle cleat assemblies of this particular kind typically include a spring housing and an overlaying bottom plate configured to be attached to the sole of a user's shoe. The spring housing and bottom plate, together, define a central opening sized and configured to conformably receive a clipless bicycle pedal. The spring housing supports one or more spring clips adjacent to the central opening, for engaging and releasably retaining the clipless bicycle pedal.

When the cleat assembly is disengaged from a pedal and the user is walking about on the ground, the cleat assembly's bottom plate is in direct contact with the ground. Debris such as dirt, sand, mud and rocks can enter the central opening of the cleat assembly as the user walks about. Once debris enters the central opening, it can impede the spring clip's ability to accept the pedal. Eventually, the central opening can accumulate an amount of debris that prevents entirely the insertion of the pedal into the cleat assembly.

In addition to making it more difficult to insert the pedal into the cleat assembly, the presence of debris in the central opening can impede the spring clip's ability to securely engage and releasably retain the pedal. As a result, the user can have the false impression that the pedal is properly seated in the cleat assembly when in fact it is not.

The presence of debris such as sand and dirt in the central opening of the cleat assembly can also increase the rate at which the cleat assembly components wear out during engagement and disengagement of the cleat assembly and the pedal.

It should be appreciated from the foregoing description that there is a need for an improved cleat assembly that overcomes the drawbacks discussed above. Specifically, there is a need for an improved cleat assembly that inhibits debris from entering the central opening of the cleat assembly when a user's shoe is disengaged from a pedal and the user is walking about on the ground. The present invention satisfies these needs and provides further related advantages.

SUMMARY OF THE INVENTION

The present invention can be embodied in a bicycle cleat/cover assembly. In this embodiment of the invention, the assembly includes a bicycle cleat and an aperture cover. The bicycle cleat is configured to releasably engage a clipless bicycle pedal, including having an aperture for receiving at least a portion of the clipless bicycle pedal. The aperture cover of the bicycle cleat/cover assembly is sized and shaped to be received in the bicycle cleat aperture when the bicycle cleat is disengaged from the clipless bicycle pedal.

In other, more detailed features of the invention, the aperture cover of the bicycle cleat cover assembly includes a bottom portion, a collar spaced from the bottom portion along an axis, and a sidewall extending from the bottom portion to the collar. In another embodiment, the aperture cover's collar extends radially outward beyond the sidewall to form a lip.

In another embodiment of the assembly, the aperture cover further includes a pair of protrusions. Each of the protrusions has a top portion that extends axially above the lip of the aperture cover's collar. In this embodiment, the top portion of one protrusion is separated from the top portion of the other protrusion by a gap such that the pair of protrusions can frictionally retain a second pair of protrusions of a substantially identical second aperture cover that has been offset by a ninety-degree angle.

In a further aspect of the invention, the collar of the assembly's aperture cover has four segments of equal circumferential length such that each segment of the collar has two adjacent segments and one non-adjacent segment. The non-adjacent segments of the collar have substantially identical curved top surfaces. The adjacent segments of the collar have curved top surfaces that are complementary, such that the aperture cover can mate with an identical second aperture cover that has been offset by a ninety-degree angle.

In other, more detailed features of the invention, the sidewall of the assembly's aperture cover has a beveled outer surface tapering toward the bottom portion. In another embodiment of this invention, a channel is formed in the sidewall of the aperture cover. The channel starts at a cutout formed at an intersection of the sidewall and the bottom portion and extends circumferentially about a portion of the sidewall. In yet another embodiment of this invention, a protuberance is formed in the channel, the protuberance extending radially outward within the channel.

The present invention can also be embodied in a bicycle cleat cover device having a bottom portion, a collar spaced from the bottom portion along an axis, a sidewall extending from the bottom portion to the collar, and a pair of protrusions. The cover device's collar extends radially outward beyond the sidewall to form a lip. Each of the cover device's protrusions has a top portion that extends axially above the lip. In this embodiment, the top portion of one protrusion is separated from the top portion of the other protrusion by a gap such that the pair of protrusions can frictionally retain a second pair of protrusions of a substantially identical second bicycle cleat cover device that has been offset by a ninety-degree angle.

In another embodiment of the invention, the cover device's collar has four segments of equal circumferential length such that each segment of the collar has two adjacent segments and one non-adjacent segment. The non-adjacent segments of the collar have substantially identical curved top surfaces. The adjacent segments of the collar have curved top surfaces that are complementary, such that the aperture cover can mate with an identical second aperture cover that has been offset by a ninety-degree angle.

In other, more detailed features of the invention, the cover device's sidewall has a beveled outer surface tapering toward the bottom portion.

In another embodiment, a channel is formed in the sidewall of the cover device. The channel starts at a cutout formed at an intersection of the sidewall and the bottom portion and extends circumferentially about a portion of the sidewall. In a further aspect of the invention, a protuberance is formed in the channel, the protuberance extending radially outward within the channel.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

With reference now to the illustrative drawings, and particularly to FIGS. 1-5, there is shown an embodiment of a cover device 10 for a bicycle cleat assembly in accordance with the invention, the cover device including a main body 14 and an actuator 16. The main body defines a longitudinal axis 18, and comprises a collar 20 and a bottom portion 22 opposite the collar, and a sidewall 24 extending axially between the collar and the bottom portion. The actuator comprises two graspable protrusions 44, 50 for use in inserting and extracting the cover device from the cleat assembly. The collar 20 extends radially outward beyond the sidewall 24 of the cover device, forming a lip 58 (best illustrated in FIGS. 2-3, 7-8).

The cover device 10 can be configured to be releasably secured within an aperture 34 formed in a cleat assembly 12 (FIG. 6A). The cleat assembly is configured for attachment to the sole of a user's shoe and for releasable securement to a bicycle pedal 60 (FIG. 6B). The particular cleat assembly depicted in FIG. 6A is configured for attachment to the user's left shoe, but it will be appreciated that a similar cleat assembly could be oppositely configured for attachment to the user's right shoe. The cleat assembly includes a base plate 62, a spring housing 64 and a steel bottom plate 66. An elastomeric bottom cover 78 can be attached to the bottom surface of the steel bottom plate and disposed over substantially the entire bottom surface of the bottom plate around the aperture 34 (FIG. 9). The spring housing and bottom plate, together, define the cleat assembly aperture that is sized and shaped to conformably receive the pedal. The spring housing contains a horseshoe-shaped spring clip 68 that includes a first radially inwardly extending tongue 70 and a second diametrically opposed radially inwardly extending tongue 72. The spring clip tongues 70 and 72 releasably engage complimentary shaped recesses 74 and 76 formed in the forward and rearward edges respectively of the pedal (FIG. 6B) when the pedal is fully inserted into the cleat assembly aperture.

The cleat assembly cover device depicted is sized and configured to provide a friction fit between the main body 14 and the cleat assembly aperture 34. The actuator 16 of the cover device is positioned near the collar 20, and the bottom portion 22 of the cover device comprises a leading end upon reception into the cleat assembly aperture. The cleat assembly cover device can comprise a resilient deformable material such as a molded elastomeric material (e.g., polyurethane).

More particularly, as illustrated in FIGS. 2 and 3, the cover device 10 further includes a receiving region 28 formed in the sidewall 24. Although not visible in FIGS. 2 and 3, the illustrated embodiment has a second identical receiving region formed in the diametrically opposed region of the sidewall. The following description is limited to just one of the two identical, and diametrically opposed, receiving regions formed in the sidewall of the cover device. The receiving region includes a cutout 30 and a channel 32. The cutout of the sidewall forms a radially inwardly extending depression beginning at the bottom portion 22 of the cover device, the cutout being shaped and configured to receive one of the spring clip's radially inwardly extending tongues 70 or 72 (FIG. 6A) when the cover device is inserted into the cleat assembly aperture. The channel is in communication with the cutout and extends circumferentially in a plane generally orthogonal to the cover device's longitudinal axis 18, the channel being shaped and configured to receive one of the spring clip's radially inwardly extending tongues 70 or 72 upon angular rotation of the cover device about its longitudinal axis following insertion into the cleat assembly aperture 34. This feature reduces the likelihood that the cover device will accidentally disengage from the cleat assembly aperture when the user is walking about on the ground.

The channel 32 of the cover device 10 further comprises a first leg 36 adjacent to the cutout 30, a protuberance 38, a second leg 40, and a stop 42. The protuberance of the channel is located between the first leg and the second leg of the channel and extends radially outwardly. The protuberance is sized and configured to frictionally engage one of the spring clip's radially inwardly extending tongues 70 or 72. The second leg of the channel terminates at the stop and has a circumferential length configured to receive one of the spring clip's radially inwardly extending tongues 70 or 72. The protuberance is adapted to allow the one of the spring clip's tongues to snap into or out of the second leg of the channel upon application of sufficient torque to the cleat assembly cover device to overcome the frictional engagement between the protuberance and the spring clip's tongue.

The collar 20 of this preferred embodiment has four segments 80, 82, 84 and 86 of equal circumferential length, each segment having two adjacent segments and one non-adjacent segment. The non-adjacent segments of the collar have substantially identical curved top surfaces, whereas the adjacent segments of the collar have curved top surfaces that are complementary to one another. As a result, the device cover can mate with an identical second device cover that has been offset by a ninety-degree angle (best illustrated in FIGS. 2, 3).

The actuator 16 of the cleat assembly cover device 10 further includes a first actuator protrusion 44 having a bottom end 46 joined to the top surface of the bottom portion 22 of the cover device and a terminal end 48 opposite the bottom end, and a second actuator protrusion 50 also having its bottom end 52 joined to the top surface of the bottom portion 22 of the cover device, and a terminal end 54 opposite the bottom end. The first and second actuator protrusions extend axially such that the terminal ends of the first and second actuator protrusions project beyond at least a portion of the collar 20 (best illustrated in FIGS. 2 and 3).

More particularly, the terminal ends 48 and 54 of the first and second actuator protrusions 44, 50 of the actuator 16 are spaced from one another a distance 56 (best illustrated in FIGS. 5A, 5B). The space between the first and second actuator protrusions can receive the terminal ends 48′, 54′ of first and second actuator protrusions 44′, 50′ of an identical second cleat assembly cover device 10′, the two pairs of actuator protrusions contacting and frictionally retaining each other in a closed orientation resulting in the proximal end 20 of the first cleat assembly cover device 10 being substantially in contact with the proximal end 20′ of the second cleat assembly cover device 10′ (best illustrated in FIGS. 7, 8).

Although the invention has been described in detail with reference only to the presently preferred embodiments, those skilled in the art will appreciate that various modifications can be made without departing from the invention. Accordingly, the invention is defined only by the following claims.
