DETAILED DESCRIPTION
A. Overview
[0044]
B. Knob
[0045] This structure acts as the portion of the handle for actuating and adjusting the handlebar assembly by hand, without a tool or instrument, as referenced in the Summary above. In one application, the knob may be rotated by hand in a clockwise or counter-clockwise rotation to perform the threading, tightening and locking motion of the assembly.
[0046] The knob (10) of this assembly acts as the handle for which the user will grab then turn to fasten, tighten or lock the bar end assembly inside the handlebar (50). The outside of the knob (10) can be any size, shape or length, but is preferably sized to accommodate gripping by hand during the threading, tightening and locking process described above. The knob (10) can be made of any solid material strong enough to hold the threaded stud in place.
[0047] The inside cavity of the knob has a cylindrical barrel like structure for the non-threaded expansion retaining block (30) to fit over and then rotate as the assembly actuates. The outside dimensions of this cylindrical barrel preferably conform to the inside dimensions of the Non-threaded expansion block (3). In one embodiment, this conformity provides for an interference or near-interference fit.
C. Threaded Stud
[0048] The threaded stud is preferably a male threaded post that may be inserted and coupled with a corresponding female threaded expansion retaining block (40). The threaded stud is preferably used to complete the threading, tightening and locking process described above, which moves the threaded expansion retaining block (40) along the threads towards the knob (10). This process in turn causes the threaded stud to slide against and compress the non-threaded expansion retaining block (30) against the inside walls of the handlebar (50).
[0049] The threaded stud (20) is preferably held securely by the knob so that when a user turns the knob, the threaded stud (20) turns along with the knob.
[0050] The threaded stud (20) is preferably cylindrical in shape and is long enough to extend through the non-threaded expansion retaining block (30), and for inserting into the threaded expansion retaining block (40). The threaded stud (20) has one or more threads that run along the length of the cylinder, similar to a machine screw. The one or more threads can vary in size, and serve to retain the screwing function needed to pull the threaded expansion retaining block (40) closer to the knob (10) when the knob (10) and threaded stud (20) are turned.
D. Non-Threaded Expansion Retaining Block
[0051] This component preferably resides between the compression of the knob (10) and the threaded expansion retaining block (40) when assembled. The angled face of the non-threaded expansion retaining block (30) preferably contacts the angled face of the threaded expansion retaining block (40) and permits each component to move opposite the other to perform the tightening and locking motion. The outside surface of the non-threaded expansion retaining block (30) is forced against the inside wall of the handlebar (50) to perform the tightening and locking motion.
[0052] In embodiments, the non-threaded expansion retaining block (30) is positioned between the knob (10) and the threaded expansion retaining block (40) in an assembly state, and assists in the locking motion. The non-threaded expansion retaining block is essentially unrestricted until the knob (10) is turned enough so that the threaded expansion retaining block (40) moves up the threads enough to come in contact with the angled face of the non-threaded expansion retaining block (30). At this point, the outer faces compress against the inner wall(s) of the handlebar (50), thereby securing the assembly.
[0053] The outer surface(s) of the non-threaded expansion retaining block (30) are preferably configured in a way so that the surface(s) come in contact with and create friction against the inner wall(s) of the handlebar (50) to complete the tightening and locking action of the assembly. The outer dimensions of this structure need not match the inner dimensions of the handlebar (50) as long as there are points of contact with the inner walls of the handlebar (50). The inner dimensions of the non-threaded expansion retaining block (30) preferably conform to the outer dimensions of the knob's (10) inside cylindrical barrel so that this structure can fit over and rotate around the barrel of the knob (10). The inside dimensions of this structure should be large enough to allow the threaded stud (20) to move freely as the non-threaded expansion retaining block (30) slides as the locking action described above is performed.
E. Threaded Expansion Retaining Block
[0054] In embodiments, the threaded expansion retaining block (40) is coupled with the threaded stud (20). When the tightening motion of the assembly occurs, the threaded expansion retaining block (40) moves toward the knob (10) along the threads in a tightening fashion. The angled face of the threaded expansion retaining block (40) preferably rests against the angle face of the non-threaded expansion retaining block (30). The threaded expansion retaining block (40) then slides up the face of the non-threaded expansion retaining block (30) and compresses against the inside walls of the handlebar (50) to aid in the tightening and locking motion of the assembly.
[0055] The threaded expansion retaining block (40) thereby acts as a compressing body, which by moving up the threaded stud (20), as the assembly is actuated, achieves the locking process described above. During this locking process, the threaded expansion retaining block (40) translates along the one or more threads until contacting the non-threaded expansion retaining block's (30) angle face. At this time, as the action of the assembly continues, this structure slides upward along the angled face of the non-threaded expansion retaining block (30) until the outside surfaces contact the inner wall(s) of the handlebar (50) to complete the tightening and locking process.
[0056] The outer surface(s) of the threaded expansion retaining block (40) are preferably oriented so that these surface(s) come in contact with and create friction against the inner wall(s) of the handlebar (50) to complete the tightening and locking process during assembly of the handlebar assembly. The outer dimensions of the threaded expansion retaining block (40) need not match the inner dimensions of the handlebar precisely, so long as there are points of contact with the inner walls of the handlebar (50). The inner dimensions of the threaded expansion retaining block (40) are preferably threaded to match or otherwise be coupled with the threads on the threaded stud (20) so that when the knob (10) and threaded stud (20) are rotated, the threaded expansion retaining block (40) moves (by rotational translation) closer to the knob (10).
F. Handlebar
[0057] This structure acts as a housing for both the non-threaded expansion retaining block (30) and the threaded expansion retaining block (40). During the tightening and locking motion of the assembly, both expansion retaining blocks (30, 40) compress against the inside walls of the handlebar (50) to complete the tightening and locking motion of the entire assembly.
[0058] The handlebar (50) may also serve as the housing for the bar end assembly. When the bar end assembly is secured to the handlebar (50), the bar end assembly will lock to this structure. The handlebar (50) also serves as a handle for a non-specific object, and may receive accessories, grips and other articles at the user's preference.
[0059] The outside surface of the handlebar (50) is intended to be gripped by hand and act as a handle. The handlebar (50) assembly's outside dimensions can vary in both size and shape without impairing the function of the bar end assembly described above. The inside dimensions of the handlebar (50) preferably facilitate, but not necessarily match, the outside dimensions of both the non-threaded expansion retaining block (30) and the threaded expansion retaining block (40) as long as there is contact between the outside of the non-threaded expansion retaining block (30), the outside of the threaded expansion retaining block (40) and the inside wall of the handlebar (50).
G. Connections of Components and Sub-Components of Invention
[0060] In embodiments, the knob (10) connects to the threaded Stud (20) as shown in
H. Alternative Embodiments of Invention
[0061] The expansion retaining blocks (30, 40) of the handlebar assembly may vary in shape, size and style, while still permitting the above-described expansion and contact with the inside walls of the handlebar (50). The material of these blocks can also perform the expansion functionality by flexing as each block is rotated or otherwise positioned against the inside wall of the handlebar (50).
[0062] The inside walls of the handlebar (50) of this assembly can vary in shape, size and style as long as these inside walls accept and facilitate the tightening and locking function of the bar end assembly.
[0063] The amount of parts in the assembly can be greater than described above as long as the assembly performs the same expansion action against the inside walls of the handlebar (50).
I. Operation of Preferred Embodiment
[0064] Methods of assembly, disassembly, reassembly and modification of the handlebar assembly are also contained herein. In one embodiment, the user first inserts the bar end assembly, which includes the knob (10), threaded stud (20), non-threaded expansion retaining block (30) and the threaded expansion retaining block (40), inside the handlebar (50). Next, the user turns the knob (10) in a direction to tightens the bar end assembly relative to the handlebar (50). This tightening motion moves the non-threaded expansion retaining block (30) and the threaded expansion retaining block (40) so each moves along the other's angled face in opposing directions, as illustrated in the Figures and described above. This opposing expansion motion compresses the non-threaded expansion retaining block (30) and the threaded expansion retaining block (40) against the inner walls of the handlebar (50) to complete the tightening and locking motion of the bar end assembly to the handlebar (50).
[0065] If the user wishes to remove, exchange or replace the existing bar end(s), the user turns the knob (10) in the direction which loosens the bar end assembly. This decreases the expansion movement of the non-threaded expansion retaining block (30) and the threaded expansion retaining block (40).
[0066] Additional configurations of the handlebar assembly according to another embodiment are shown and described in relation to
[0067] The assembly according to this embodiment preferably comprises a knob, a threaded shaft, a locking nut, one or more spring retaining bracket(s), and a retaining band as depicted, for example, in
[0068] According to a preferred embodiment, in operation, the locking nut is allowed to translate along the linear axis of the threaded shaft, thereby increasing or decreasing (per the user's preference) the distance between the knob and the locking nut. This movement in turn increases or decreases the distance between the pairs of spring retaining brackets, as shown in
[0069] A slot located along the perimeter of the spring retaining bracket(s) permits this expansion and, as the retaining band imparts a force on the spring retaining brackets. By imparting this movement on the spring retaining bracket(s), the series of radially positioned teeth shown in
[0070] The components described above are preferably comprised of steel, aluminum, steel alloy, aluminum alloy, graphite, metal alloy or equivalent, with the exception of the retaining band, which is preferably a rubber or similar synthetic material. In alternative embodiments, the materials may be modified to suit the particular application. In certain embodiments, the components may be comprised of stainless steel. The knob preferably comprises a gnurled or textured surface for improved purchase when tightening or loosening the knob, as a user's grip may be compromised due to the presence of water, oils, mud, debris, etc.
[0071] In one embodiment, two assemblies like the one shown in
[0072] The present disclosure also relates to the mounting of boots or similar equipment to a piece of equipment, such as a wakeboard of waterski. Turning now to
J. Wakeboard or Water Ski Binding/Boot
[0073] This structure is any device that a user would insert their foot into to be secured to a wakeboard or waterski and includes a base plate/chassis, as described and shown herein.
[0074] A wakeboard or water ski binding/boot (10) comprises a shoe-like structure or any structure in which you can insert your foot such that this boot (10) and your foot may be bound, attached or secured to one another, and then secured to a wakeboard or water ski (30) having the binding system described herein. This device may also consist of a base plate/chassis (11) that provides the means for mounting and securing the boot (10) to the wakeboard or water ski (30).
[0075] This binding/boot (10) may be a shoe, sandal, sock, sleeve or boot, or anything similar object worn on the foot. It may also have straps, strings, laces, buckles or any devices used to tighten and secure the foot inside the binding/boot (10). The chassis/base plate (11) of the binding/boot (10) is typically attached permanently to the bottom of the binding/boot (10) shoe like structure, but is not limited to being permanently attached, and in one embodiment is not considered a separate apparatus from the boot (10). The base plate/chassis (11) holds the vertical engagement teeth (12) interface for securely attaching the binding/boot (10) to the wakeboard or waterski (30). The base plate/chassis (11) also has but does not require a base plate/chassis slot (13) for assisting a user in securing the base plate/chassis (11) to the wakeboard or waterski (30). Several variations of the elements in combination with each other, or with other elements described above, is expressly contemplated.
K. Mounting Bracket
[0076] The mounting bracket structure is used to secure the wakeboard or waterski binding/boot to the wakeboard or water ski. In a preferred embodiment, the mounting bracket (20) structure is used to secure the binding/boot (10) to the wakeboard or waterski (30) and has integrated teeth (21) aligned with and that join with the teeth on the binding/boot (10) to ensure that the bindings does not rotate.
[0077] The mounting bracket (20) can have many different shapes and can be made out of different materials as long as the mounting bracket has vertical teeth (21) that join with vertical engagement teeth (12) on the binding to complete the assembly. The mounting bracket (20) also has but does not require a male engagement tongue (22) that assists in securing the base plate/chassis (11) to the wakeboard or waterski mounting inserts (31).
L. Wakeboard or Water Ski
[0078] According to various embodiments described herein, any board or ski used for water sports activities in which the user mounts a wakeboard or waterski by using the bindings/boots is contemplated for use with the present invention. In other embodiments, any other apparatus (including snowboards, downhill or cross-country skis, skydiving boards, etc.) may be used in connection with the present disclosure.
[0079] In a preferred embodiment, a board or ski (including those used to ride across water) has mounting inserts (31), which assist in serving as a fastening system, and which are intergrated into the wakeboard or waterski (30) to accommodate the fasteners (40) and fastening of binding/boots (10) to the board (30).
[0080] The wakeboard or ski (30) can have many shapes, designs and be made of different materials. Typically, the board has a mounting system (31) that accommodates securing bindings/boots (10) to the board or ski (30). Additional elements of the binding system are also typical for the particular board the binding system is associated with, as described in further detail below.
M. Fastener
[0081] The fastener may be made of any suitable structure, but in a preferred embodiment is comprised of one or more threaded screws, which are used to securely tighten and complete the connection between the wakeboard or water ski binding/boot, mounting bracket and the wakeboard or water ski.
[0082] The fastener (40) is preferably inserted through the mounting bracket (20) to secure the binding/boot to the board. It is expressly understood that the fastener (40) is not limited to a screw, and can be of any other device known to one of ordinary skill in the art that would secure the mounting bracket (20) and base plate/chassis (11) to the wakeboard or water ski (30). Thus, while the fastener (40) is usually a threaded screw, it is not limited to having threads, and may vary in length and size, so long as it serves to fasten the binding/boot (10) to the board or ski (30). In a preferred embodiment, the fastener may be adjusted either by using a tool or by canter lever motion by hand.
N. Connections of Main Elements and Sub Elements of Invention
[0083] The fastener (40) is preferably inserted through the mounting bracket (20). The mounting bracket (20) and fastener (40) are then inserted into the engagement teeth (12) interface on the binding/boot (10), one on each side as depicted in the drawing figures. Then, this assembly is fastened to the wakeboard or water ski (30) using its mounting inserts (31).
O. Alternative Embodiments of Invention
[0084] Two mounting brackets (20) and fasteners (40) are typically used, one on each side of the boot/binding (10) base plate/chassis (11), to fasten the binding/boot (10) to the board (30). However, the system is not limited to having only two, and may have less than two or more than two without departing from the spirit of the disclosure. Thus, as long as the vertical engagement teeth (12) and engagement teeth (12) union is achieved to secure the boot/binding (40) to the board (30), the benefits of the binding system is achieved. The organization of the elements described herein is not limited to having the mounting brackets (20) on each side either, as long as the same vertical teeth union is achieved to secure the boot/binding (10) to the board (30).
P. Operation of Preferred Embodiment
[0085] Wakeboard or waterski boot/bindings (10) are thereby connected to a wakeboard or waterski (30) using an attachment system that is integrated into the bottom of the boot/binding in most cases, but are not limited to being integrated. In some cases the boot portion and attachment system are separate parts, which may form an assembly to complete the boot/binding that is to be attached to the board. In any case, the base plate or chassis portion of either style boot/binding contains an integrated adjustment system used for accomplishing two processes; attaching the boot/bindings to a wakeboard or waterski and also setting a desired position or adjusting the stance/position at which the user places his feet on the board. These processes may occur at the same time, or may be separate. These two processes are preferably accomplished by using additional mounting brackets and fasteners.
[0086] On the binding/boot base plate or chassis there are incremental teeth, notches or otherwise apparatus/indicia to permit the user to set a desired stance angle or boot position. In a preferred embodiment, this adjustment permits the boot to be positioned relative to the longitudinal axis of the board in a wide range of positions. In a preferred embodiment, this range encompasses approximately 60 degrees of movement from one extreme boot position to the other extreme boot position. In a most preferred embodiment, this range encompasses approximately 45 degrees of movement from one extreme position to the opposite extreme position.
[0087] In a preferred embodiment, there are also opposing teeth on the mounting brackets that mate in a male/female fashion with the teeth on the base plate/chassis portion of the boot/binding. These teeth, notches or otherwise are organized in a circular fashion on both the base plate/chassis so the user can rotate the binding/boot about a center point and then set the desired stance angle by placing the mounting bracket into desired tooth or notch while securing the boot/binding assembly to the wakeboard or waterski.
[0088] The fastener may be inserted into, on or through the mounting bracket. The mounting bracket and fastener are placed over, onto or otherwise joining with the base plate/chassis portion of the wakeboard or waterski boot/binding at the desired stance adjustment. This assembly of fasteners, mounting brackets and binding/boot are then secured to the wakeboard or waterski by inserting the fastener into the mounting inserts on the wakeboard or waterski and then each fastener is tightened to complete the secure bond between the wakeboard or waterski and the boot/binding assembly to keep the stance adjustment at the desired locations or angles without change or prolonged use.
[0089] In at least one embodiment, the teeth on both the base plate/chassis and the mounting brackets lay in a horizontal fashion so the peaks and valleys of the teeth, notches or otherwise lay horizontally stacked parallel to the surface of the board. The problem with this orientation is that the integrity of the assembly staying in place or at the desired set stance adjustment relies solely on fasteners staying completely tight. If the fasteners in this style assembly loosen slightly, the stance can change without notice and does not stay set at the desired adjustment because the mounting brackets slide up and over the peaks of the teeth to the next increment, which is not desired and can cause injury to the user if it changes drastically. In some cases they can skip very far across multiple teeth or increments and the stance angles can change drastically.
[0090] In an alternate embodiment, the teeth are turned or rotated 90 degrees, such that the peaks and valleys of the plurality of teeth are aligned vertically, not horizontally, or are sitting substantially perpendicular to the surface of the board. This orientation does not allow the boot/binding set stance adjustment to change even if the fasteners loosen and the integrity of the assembly staying at the set adjustment relies on the height of the teeth, notches or otherwise and the fact the assembly cannot move laterally because the fasteners are inserted into the mounting inserts of the wakeboard or waterski.
