The following description of various examples is merely illustrative in nature and is in no way intended to limit the disclosure, its application, or uses. Additionally, the advantages provided by the examples and embodiments described below are illustrative in nature and not all examples and embodiments provide the same advantages or the same degree of advantages.
This Detailed Description includes the following sections, which follow immediately below: (1) Definitions; (2) Overview; (3) Examples, Components, and Alternatives; (4) Advantages, Features, and Benefits; and (5) Conclusion. The Examples, Components, and Alternatives section is further divided into subsections, each of which is labeled accordingly.
The following definitions apply herein, unless otherwise indicated.
“Comprising,” “including,” and “having” (and conjugations thereof) are used interchangeably to mean including but not necessarily limited to, and are open-ended terms not intended to exclude additional, unrecited elements or method steps.
Terms such as “first”, “second”, and “third” are used to distinguish or identify various members of a group, or the like, and are not intended to show serial or numerical limitation.
“AKA” means “also known as,” and may be used to indicate an alternative or corresponding term for a given element or elements.
“Elongate” or “elongated” refers to an object or aperture that has a length greater than its own width, although the width need not be uniform. For example, an elongate slot may be elliptical or stadium-shaped, and an elongate candlestick may have a height greater than its tapering diameter. As a negative example, a circular aperture would not be considered an elongate aperture.
The terms “inboard,” “outboard,” “forward,” “rearward,” and the like are intended to be understood in the context of a host vehicle on which systems described herein may be mounted or otherwise attached. For example, “outboard” may indicate a relative position that is laterally farther from the longitudinal centerline of the vehicle, or a direction that is away from the vehicle centerline. Conversely, “inboard” may indicate a direction toward the centerline, or a relative position that is closer to the centerline. Similarly, “forward” means toward the front portion of the vehicle, and “rearward” means toward the rear of the vehicle. In the absence of a host vehicle, the same directional terms may be used as if the vehicle were present. For example, even when viewed in isolation, a device may have a “forward” edge, based on the fact that the device would be installed with the edge in question facing in the direction of the front portion of the host vehicle.
The terms “longitudinally” and “laterally” (and the like) are intended to be understood such that the lateral direction is generally parallel to the axis of rotation of the wheel and the longitudinal direction is generally parallel to the vehicle's direction of travel.
“Coupled” means connected, either permanently or releasably, whether directly or indirectly through intervening components.
“Resilient” describes a material or structure configured to respond to normal operating loads (e.g., when compressed) by deforming elastically and returning to an original shape or position when unloaded.
“Rigid” describes a material or structure configured to be stiff, non-deformable, or substantially lacking in flexibility under normal operating conditions.
“Elastic” describes a material or structure configured to spontaneously resume its former shape after being stretched or expanded.
“Providing,” in the context of a method, may include receiving, obtaining, purchasing, manufacturing, generating, processing, preprocessing, and/or the like, such that the object or material provided is in a state and configuration for other steps to be carried out.
In this disclosure, one or more publications, patents, and/or patent applications may be incorporated by reference. However, such material is only incorporated to the extent that no conflict exists between the incorporated material and the statements and drawings set forth herein. In the event of any such conflict, including any conflict in terminology, the present disclosure is controlling.
In general, a fender assembly in accordance with the present teachings may include multiple elements coupled together, such that the assembly is removably attachable to a one-wheeled skateboard (or similar vehicle) and such that an arched fender of the assembly is pivotable and/or detachable with respect to a base or “fender delete” portion. Examples of suitable one-wheeled vehicles are disclosed in U.S. Pat. No. 10,456,658.
The latchable and pivotable fender arch of the present disclosure has a latching end and a hinged end, such that the latching end of the arch can be selectively raised and lowered like the hood or bonnet of a car. This facilitates easy access to the underlying tire while ensuring the arch of the fender remains securely fastened to the vehicle during normal use (e.g., riding). The removable nature of the pivotable fender arch facilitates a user switching between operating the vehicle with a covered wheel and operating the vehicle with an uncovered wheel. For example, the user can remove the fender arch by hand (without tools), by unlatching one end and manually detaching the other, rather than needing to remove fasteners to detach a full fender from the vehicle and then refasten a separate fender delete.
The following sections describe selected aspects of illustrative fender assemblies, as well as related systems and/or methods. The examples in these sections are intended for illustration and should not be interpreted as limiting the scope of the present disclosure. Each section may include one or more distinct embodiments or examples, and/or contextual or related information, function, and/or structure.
I. Illustrative Fender Assembly
As shown in
Fender assembly 100 includes two portions: a detachable fender 108 and a base frame 110. The fender may be referred to as a fender portion or fender arch. The base frame may be referred to as a frame. In some examples, the base frame may be referred to as a ring or an annulus or a fender delete.
With continuing reference to
Frame 110 includes a first leg 112 having a first coupling portion 114 and a second leg 116 including a first latch portion 118. Frame 110 is configured to be coupled to vehicle 102 with first leg 112 and second leg 116 on opposite sides of wheel 106. As best viewed in
Fender 108 includes an arcuate sheet configured to curve over the wheel, and has a first end 120 and a second end 122. First end 120 has a second coupling portion 124 configured to releasably mate with first coupling portion 114 of frame 110 to form a manually releasable joint 126. Second end 122 has a second latch portion 128 configured to mate with first latch portion 118 of frame 110 to releasably secure the second end to the frame. In some examples, the fender has a circular curvature. In some examples, the fender has an elliptical curvature. Fender 108 curves through a selected angle to provide a desired protection, and may curve through any suitable angle such as at least 90 degrees or such as 180 degrees, e.g., depending on the configuration of the wheel opening.
In some examples, joint 126 is a pivoting joint collectively formed by the first and second coupling portions and the first and second coupling portions may be referred to as first and second hinge portions, respectively. An axis of rotation of joint 126 may be oriented transverse to direction of travel D, i.e., such that the axis is oriented transverse to a longitudinal axis of fender 108 and second end 122 of the fender is configured to be raised up and down relative to base frame 110. (See
In some examples, first coupling portion 114 includes a first hook and second coupling portion 124 includes a second hook, such that the first and second hooks are configured to hook together. For example, the second hook of fender 108 may be open toward the second end of fender 108 (i.e., the other end), such that the hook of the fender grabs around an outer end of the hook of the base frame relative to the wheel position.
In some examples, including in some examples where the first and second coupling portions comprise hooks, first coupling portion 114 includes a first hinge knuckle 130 and the second coupling portion includes a second hinge knuckle 132, such that the first and second hinge knuckles are configured to collectively form a releasable hinge 134. For example, each of the hinge knuckles may be open, such that the curls or partial tubes forming the knuckles can grab onto each other on one direction but can also be quickly released in an opposite direction (e.g., both directions being generally parallel to direction D). In operation, latching of the other end of the fender to the base frame prevents release of the hinge knuckles from each other, while unlatching permits pivoting and/or release, depending on how the user manipulates the unlatched fender. See the sectional view of
As depicted in
In some examples, one of the first coupling portion and the second coupling portion includes a hinge knuckle and the other of the first coupling portion and the second coupling portion includes a hinge pin, such that the hinge knuckle and the hinge pin are configured to collectively form a releasable hinge.
With reference to the sectional view of
Turning now to the latching end of the assembly, one of the first latch portion 118 and the second latch portion 128 comprises a recess and the other of the first latch portion and the second latch portion comprises a hook. In some examples, second latch portion 128 of the fender comprises a hook 138 and first latch portion 118 of the base frame comprises a recess 146. Recess 146 may include any suitable opening, aperture, recess, or depression in the base frame configured to securely receive hook 138.
Hook 138 comprises an actuator accessible on an exterior of the fender assembly (e.g., on a user-accessible face of second end 122 of the fender). As depicted in the example of
As mentioned above, base frame 110 may in some examples define a ring or an annulus or a fender delete. For example, frame 110 may comprise a third leg 150 and a fourth leg 152, these side legs in combination with the first and second end legs forming a rectangular or generally rectangular annulus. Fender assembly 100 may be coupled to the body of vehicle 102 using multi-use fasteners, such as bolts or screws, secured in apertures 162 of base frame 110. Optionally, an outer, downward-extending ridge or rib 156 and/or tabs 154 of third leg 150 and fourth leg 152 may interface or mate with corresponding features of the vehicle body. Optionally, a mud flap or skirt 148 may extend downward from the first or second leg to cover a corresponding opening or openings in the body of vehicle 102.
In some examples, fender 108 includes one or more flanges or tabs 158 extending generally downward from first end 120 and configured to be disposed on an inner or wheel-facing side of first leg 112 when the fender is coupled to the base frame. Tabs 158 are configured to prevent or resist undesired movement of first end 120 in a longitudinal direction that would result in decoupling of the components of joint 126 and accidental disengagement of the fender from the base frame. For example, if a longitudinal force is applied to the fender, tabs 158 may eventually abut first frame leg 112, arresting movement of the fender before portion 124 becomes disengaged from portion 114. In some examples, fender 108 includes one or more tabs or flanges 160 extending generally downward from second end 122 on a wheel-facing side of second leg 116. Similar to tabs 158, flange 160 is configured to prevent or resist undesired movement of second end 122 in a longitudinal direction that would result in unlatching and accidental disengagement of the fender from the base frame.
