Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a binding system and method having interchangeable chassis (frames) for use with such a binding, each chassis (frame) having a sports motive mechanism such as an inline skate wheel set, an aggressive or freestyle inline skate wheel set, an ice skating blade, a speed skating blade, a hockey skating blade, a roller skating blade (“quad”) and others.

2. Description of the Related Art

Ice skating and roller skating have been popular for a long time. In the 1980s, inline skates became popular, and thereafter aggressive inline skates for tricks and stunts. Each type of blade or wheel set conventionally also has its own boot. Having multiple sets of skates takes up a lot of room and is expensive.

The desire and need for a boot with interchangeable motive mechanisms has long been recognized. For almost a century or more, inventors have been working to make one boot with an interchangeable set of motive mechanisms. For example, U.S. Pat. No. 1,530,211 to Siemnash issued in 1925 discloses a combination skate that has an interchangeable ice skating blade and roller skating wheel set.

Inventors have continued to work on this problem. The need for interchangeability has grown substantially given inline skates, aggressive inline skates, and other new motive mechanisms that have come about since 1925.

In the aggressive or freestyle inline skating field, there are many types of frames and wheel sets. Riders frequently need to change frames, either due to damage or due to trying different tricks that require different frame structure and/or different wheels. It is also common to rotate the frame in order to rotate the wheels for longer life.

To address the issue of interchangeability using one boot, UFS or “uniform frame system” was developed by Salomon. A UFS frame uses multiple different types of frames with various types of wheel sets, but always has two bolt holes on the top formed in the exact same configuration. This means that the distance the bolt holes are apart is exactly the same and the structure of the holes (size, mating surface, etc.) is exactly the same to mate with boots or bindings having a UFS sole plate for attachment of any UFS frame.

The UFS sole plate has bolt receiving holes with internal threading to receive the threaded end of bolts that are UFS standard diameter. Therefore, a user of one type of aggressive inline frame and wheel set can change to another type of frame and wheel set, as long as both frames are UFS.

UFS bolt holes are generally at either 165 mm (for kids) or 195 mm (for adults) apart. The UFS bolt diameter is M6 (6 mm).

UFS is extremely common in the aggressive inline skating field. Every or virtually every skate manufacturer follows UFS for all or most of their aggressive inline skates. Further, for other inline skates and for roller skates and ice skates, conventionally frames are riveted to the sole of a boot. With aggressive inline skates, boots and sometimes frames can get beat up and need changing often.

The need for an easy to use and simple interchangeable boot and frame system has existed for quite some time. Others have tried but have not succeeded in a simple top mounted system, where the bolt head on the sole plate side and bolted downward.

U.S. Published Patent Application No. 2010/0225100 to DePetri teaches a system for connecting a boot to a frame housing containing multiple motive options including roller wheels, ice blades, or mini-skis using vertically oriented bolts secured from the bottom of the frame into the boot.

U.S. Pat. No. 6,070,866 to Cornelius for roller skates and U.S. Pat. No. 4,351,536 to Sandino for ice skates both teach a system for connecting a boot either directly to or through a mounting plate to a frame housing using vertical top entering bolts. However, while Cornelius and Sandino use a bolt entering from the top, they still require a nut below the frame, vitiating the advantage of having a top down mount.

A simple and easy to use system that has interchangeable frames having different motive devices, preferably other than aggressive inline skates, which are attachable by UFS with a bolt from the bottom of the frame and/or from above the frame is needed.

SUMMARY OF THE INVENTION

In one embodiment, there is a motive mechanism frame as disclosed herein, and which frame is made in accordance with UFS.

In another embodiment, there is a set of frames for inline skates and roller skates and/or ice skates and/or other motive mechanisms, which frames are each made to UFS.

In another embodiment, there is a combination of a sole plate (or a binding or boot with a sole plate) and one or more interchangeable frames with the sole plate, wherein each of the frames and sole plate are made to a common standard, and wherein at least one of the frames is for a motive mechanism other than aggressive inline skates.

A motive mechanism frame as disclosed herein other than for aggressive inline skates, wherein the frame is made in accordance with UFS and the sole plate has a threaded insert, preferably of metal, for receiving a bolt threaded from the bottom (or the top).

A motive mechanism frame as disclosed herein other than for aggressive inline skates, wherein the frame is made in accordance with UFS and also has a threaded insert disposed in the position of the UFS through holes for the frame mounting bolts.

In each of the above embodiments, the frames are preferably for skates (boots or bindings and frame type) other than for aggressive inline skates. However, they may also be used with aggressive inline skates.

Preferably, in a further variation of each of the above embodiments, there is a mechanism on at least one of the frame types or more than one of the frame types having an internally threaded member that is accessible to and adapted to receive a bolt threaded downward into the threaded member from the top of the frame, preferably of a dimension matching UFS, and for attaching the frames to the sole plate (e.g., of boots or bindings) and preferably of metal.

In another embodiment, there is a method of affixing and detaching frames to the sole plate in accordance with the above embodiments.

FIGS. 1 to 3—Conventional Aggressive or Freestyle Inline Skates and UFS:

In order to best understand embodiments of the invention, one needs to understand a standard, e.g., UFS. FIGS. 1 to 3 show UFS.

An aggressive or freestyle inline skate 2 has a boot or binding 4 with a sole plate 4a (fixed to or unitary with the boot or binding) and a frame 6 with an inline wheel set 6b. A top portion 6a of the frame 6 and the sole plate 4a are made in accordance with set standards, typically, UFS (uniform frame system).

Specifically, each UFS sole plate 4a has a bottom surface (FIG. 3) that has two threaded members 4b, each centered within an annular boss 4c and located at a specified distance U from each other. In addition, each UFS frame 6 (FIG. 2) has a top surface 6a having a pair of through holes 6c located at the center of a recess 6d, the through holes 6c also being located at the same specified distance U from each other. The diameter of the annular bosses 4c and the diameter of the recesses 6d are essentially the same and in particular such that the bosses rest in the recesses for lateral strength and alignment. The height of the bosses is also preferably the same as the depth of the recesses.

The specified distance U for an adult size skate in UFS is 195 mm. The specified distance U for a child size skate in UFS is 165 mm. There is also a channel 4e formed in the bottom surface of the sole plate. Channel 4e has a standard width W (FIG. 3), which is the same as the width W (FIG. 2) of the top 6a of the UFS frame for additional lateral support.

The threaded member is of a standard diameter and thread size to fit an M6 bolt 8 or screw (6 mm). M6 is the UFS bolt diameter size. The bolt length will vary depending on multiple factors, such as the skate, the frame, and the manufacturer. Bolt length may vary between about 13 mm and about 28 mm, or may be other lengths.

In UFS, the threaded end 8a of bolt 8 passes through the through holes 6c from the bottom of the frame (direction of arrow B in FIG. 1) and is threaded by means of its head 8b (an allen head) into insert member 4b (direction of arrow A in FIG. 1).

While some frames and wheel sets enable direct access to the bolt head 8b without removing wheels in an aggressive inline skate, sometimes the inner wheels need to be removed such as in a “flat set up,” to reach the bolts.

UFS frames and sole plates usually enable the frame to be rotated 180 degrees in a horizontal plane, so that the outer edge of the wheels 6b becomes the inner edge and vice versa. This enables the wheels to last longer.

As shown in FIGS. 1 and 2, this aggressive inline skate frame has a grinding area 7 (a concave recess in the bottom of the skate frame proximate the center and between the center two wheels.

FIGS. 4 to 7—Inline Skates Embodiment:

In FIGS. 4 to 7, there is shown an inline skate 12 having a binding 14 with a sole plate 16 attached and/or unitary therewith, and a frame 18, in accordance with a set of frames and/or set of motive sport footwear in accordance with an embodiment of the invention. The frame 18 has a set of wheels 20, such as for an inline skate, which may be an aggressive (or freestyle) inline wheel set or a recreational inline wheel set. Preferably all of the wheels have the same diameter, although they do not have to have the same diameter. Preferably the frame has no grinding area (no enlarged central recess accessible between the wheels), although it could have one.

The wheels 20 are mounted on the frame usually using allen bolts 21 as axles. The threaded ends of the bolts are seated in a threaded receptor 23. The threaded receptor is preferably a figure eight shape (or other shape that prevents rotation) held in a recess in a sidewall 18d of frame 18. This structure enables the wheel to rotate freely on the axle and the axle (allen bolt) to be tightened or loosened without the “nut” (the threaded receptor) rotating.

The frame 18 is made to UFS specifications as is the sole plate 16. The frame has a top surface 18a that has the UFS width W between sidewalls 18d. The frame also has recesses 18b with the same diameter (D), the same depth (d) of the recesses 18b and the same spacing distance U for its two through holes 18c as the UFS specification (as the corresponding parts of FIG. 2).

FIGS. 8 to 9—Sole Plate:

In FIGS. 4 to 7, there is shown an inline skate 12 having a binding 14 with a sole plate 16 attached and/or unitary therewith, and a frame 18, in accordance with a set of frames and/or set of motive sport footwear in accordance with an embodiment of the invention.

The sole plate 16 is shown in more detail in FIGS. 8 and 9, and as noted above, is also made to UFS specifications. Specifically, its underside has the same channel with width W, the same threaded member and spacing U, the same annular bosses with diameter D and height d, as the corresponding UFS parts of the UFS sole plate 4a of FIG. 3.

In addition, the top 16d of the sole plate 16 of FIGS. 8 and 9 has two recesses, preferably D-shaped recesses 16c that receive a corresponding D-shaped metal receptor 16b. The top 16d also has the threaded member 16a attached thereto preferably by being molded into (by co-molding or in molding such as molding in place) the sole plate. Preferably the recesses are noncircular and the shape of the metal receptor has the same noncircular shape to fit snuggly in the recesses without being rotatable, so a bolt may be threaded into the threaded member 16a. Metal receptor 16b is essentially a washer with its hole slightly chamfered so that a bolt can readily mate with the hole, and it will act as a guide for the threaded member 16a.

The sole plate may be formed as part of the binding (or a boot) or may be separately formed and fixed thereto.

FIGS. 10 to 12 and 12A—Roller or Quad Skates Embodiment:

In FIGS. 10 to 12, there is shown a roller (or quad) skate chassis (or frame) and wheel assembly 30, which may be attached to the sole plate 16 and therefore the binding (or boot). The frame 32 is preferably part of a set of frames and/or set of motive sport footwear in accordance with an embodiment of the invention, or may be the only frame.

The frame 32 has a wheel mounting structure 34 which includes axles for mounting four wheels 33 in two rows of two, as in a typical roller skate. There may be a brake, as in roller and inline skates.

There are also two bolts 33a that hold the wheel mounting structure 34 to the frame 32. The frame has the same sidewall width W as the width W of the UFS specifications and of the channel of the sole plate 16.

In addition, there is an annular recess 37 with the same diameter (D) as the UFS specifications and as the diameter D of the recess 18b, and has the same depth (d) as well. In the case of the roller skate frame, since the wheels 33 and/or wheel mounting structure 34 block ready access to the UFS bolt's head, and since the wheels 33 and/or wheel mounting structure 34 are not readily removable, there is a threaded insert member 36 located in the recess 37. The threaded insert member 36 preferably receives the threaded end of the same standard M6 bolts that the threaded member 16a in the sole plate receives. Accordingly, a standard M6 allen bolt may be used to fix the skate from the top of the sole plate 16, by passing through the threaded member 16a and then into the threaded insert member 36.

In this embodiment, the through hole in the frame is of a larger radius than the standard UFS specifications, so that the threaded insert member 36 may be provided therein. For example, it may be molded into, epoxied, unitarily formed in, or otherwise fixed to the rest of the frame in the position of the through hole.

FIG. 12A is a cross section of the sole plate 16 in the area of the D-shaped recesses 16c showing the D-shaped metal receptor 16b and the threaded insert member 16a. The underside of the sole plate 16 has the annular boss that fits into the recess 37 in the frame. The threaded insert member 36 is attached to the frame preferably by being molded into the frame 32 at area 32a. A UFS sized bolt 39 threads from the top through the threaded insert member 16a and into the threaded insert member 36.

In any embodiment, there may be a threaded insert (preferably of metal) affixed to the frame at the throughholes to enable top mounting where the bottom of the frame is not readily accessible (e.g., as in certain roller skates and where the motive element is a roller ball) and/or simply for convenience.

FIGS. 13 and 13A—Ice Skates Embodiment:

In FIG. 13, there is shown a frame 40 with an ice skating blade 42 fixed to the frame, e.g., by bolts 45. The top surface of the frame 40 has the same UFS compatible shape as in the embodiment of FIGS. 10 to 12, and has the threaded insert member 36 in the recess 37 of the frame as in FIG. 12A. FIG. 13A is a top view of the ice skate frame, showing the UFS configuration. Top surface 45 has sidewalls 44 located distance W apart to fit in the UFS channel 16e in the sole plate 16. Top surface 46 also has two UFS sized recesses 47 with threaded insert members 48 located in the center of the recesses for accepting M6 bolt threads. The threaded inserts are the same as threaded insert members 36 and are located at a distance of U apart from each other. If the skate blade 42 is readily removable using the bolts 45, then the threaded insert may be unnecessary. However, because an ice skate blade must be tightly fixed to the frame, with no wobble, it is preferred to use the threaded insert member 48.

FIG. 14—Binding:

In FIG. 14, there is shown the binding 14 in an open position. The binding has a front section 14a and a rear section 14b which is preferably movable between an open position as shown therein and a closed position as shown in FIG. 4. The rear section 14b may be hinged. The opening of the binding enables quick entry and/or quick exit by the rider. Also, it is desirable to make the binding adjustable, e.g., one type to accommodate kids sizes e.g. 4 to 7 and another type to accommodate adult sizes, e.g., 8 to 11. There may also be a boot as in FIGS. 1 and 3 or similar thereto. Sole plate 16 is a generally rigid member which may be affixed to and/or may be an integral or unitary part of the boot and/or the binding.

FIGS. 15 to 17—System Embodiment(s):

In FIGS. 15 to 17, there is shown the binding with the ice skate version, the roller skate (quad) version and the inline skate version, respectively. As noted above, the binding may be a boot. FIG. 15 is a combination of the binding of FIG. 14 (including the sole plate of FIGS. 8 and 9) with the ice skate frame 40 of FIGS. 13 and 13A. FIG. 16 is a combination of the binding of FIG. 14 (including the sole plate of FIGS. 8 and 9) with the quad roller skate frame 32 of FIGS. 10 and 11. FIG. 17 is a combination of the binding of FIG. 14 (including the sole plate of FIGS. 8 and 9) with the inline skate frame 18 of FIGS. 6 and 7.

Any Motive Sport Footwear e.g., ice skates, roller skates, quad skates, inline skates, skates with spherical balls as a motive interface device, skis, rails, and comparable sports or recreational devices wearable on one's feet may be made with a UFS frame in accordance with the invention. In the system, the motive sport footwear where the motive interface device, such as blades and/or roller skate wheels, is such that access to a bolt that would pass through the UFS through holes is not readily or reasonably available, is preferably made with the threaded insert of FIG. 12A and is otherwise UFS compatible.

Additionally, any motive sport footwear where there is reasonable access, such as inline skates, whether freestyle, recreational or roller hockey, may be on a frame that is UFS compatible and has the through holes of a UFS frame.

Because the sole plate is UFS compatible, the frames and thus the motive sport footwear in the system are interchangeable with each other. Therefore, there system may be made with two, three, four or even five different types of frames, and preferably at least one of which has the threaded insert. Moreover, in a variation, the frames are all interchangeable and built to the same standards, which need not necessarily be UFS specifications. However, additional significant advantage is achieved by making the frames in the system to UFS specifications. Further, while at least one frame with the threaded inserts is preferably in the system, the system can be embodied with interchangeable frames built to the same standards.

This, in a most preferred embodiment, is true regardless of the type of motive device on the frame, whether or not top or bottom mounting is required.

FIGS. 18 and 19—Threaded Insert and Bolting Variations:

As shown in FIG. 18, which is very similar to FIG. 12A, any frame may be made with the threaded insert member 36 and still bolted from the bottom using a bolt 39a (which is preferably the same as bolt 39). As shown in FIG. 19, there is a typical UFS mounting of the type shown in FIGS. 1 and 3. In this case, there is no threaded insert member 36 and the bolt 39a is used. In this situation, the frame at area 32b (corresponding to area 32a of FIG. 12a) has a standard UFS throughhole. Any of the bottom mounting frames of the invention may use this structure.

Where the bottom of the frame is readily accessible for threading and unthreading a bolt to the frame (i.e., when the motive device is either not in the way of threading and unthreading a bolt from the underside of the frame, or when the motive device or a portion thereof may be removed by simply removing a bolt or action of comparable ease and without destroying the frame and/or motive device), preferably the standard connection system of FIG. 19 is used. Where the bottom of the frame is not readily accessible, then it is preferable to use the threaded insert (such as threaded insert members 36 or 48) in the frame. Note that the metal receptor 116b and threaded insert member in the frame is preferably structured the same or substantially similar to the threaded insert member and metal receptor in the sole plate and installed such as shown in FIG. 9, i.e., by using the D-shaped (nonround) recess, and the D-shaped (or matching nonround) metal receptor 16b (which recess and D-shaped metal receptors are on the bottom side with respect to the top of the frame), and with the threaded member facing upward. Preferably, threaded member 16a and metal receptor 16b of the sole plate and their counterparts used in threaded insert members 36 and 48 in the frame are metal, even though the sole plate and/or frame may be a hard plastic or hardened rubber.

FIG. 19 shows metal receptor 116b while FIG. 12A does not. However, metal receptor 116b may be used in the embodiment of FIG. 12A and metal receptor 116b need not be used in the embodiment of FIG. 19. The metal receptor in the sole plate may be optionally used as well, although it is preferred. It would also be possible to simply embody any of the frames for a motive interface device that is not an aggressive inline skate frame as a UFS compatible frame, with the threaded insert or without it.

Another unique aspect of the invention is providing a UFS frame with a threaded insert.

All of the above variations, with frame or frames, with a system of frames and a binding or boot with a sole plate, and/or in combination with a binding or boot with a sole plate, may embody the invention. Inventive method(s) of using the frames of the system and/or of attachment of the frame(s) with or without the threaded insert to the boot or binding with sole plate is evident from the above structure and description as well.

The frames and sole plates herein may be made of any material suitable for a frame, such as metal, plastic e.g., nylon for strength and relative lightweight, polypropylene, e.g., reinforced polypropylene, or a combination of plastics and/or other materials. Threaded inserts and the threaded member are preferably metal, although possibly other materials may be suitable.

Although the invention has been described using specific terms, devices, and/or methods, such description is for illustrative purposes of the preferred embodiment(s) only. Changes may be made to the preferred embodiment(s) by those of ordinary skill in the art without departing from the scope of the present invention, which is set forth in the following claims. For example, the parts of the sole plates and frames in the preferred embodiments made to UFS may be made to another standard, although that is less preferred. In addition, it should be understood that aspects of the preferred embodiment(s) generally may be interchanged in whole or in part.
