Abstract

A frame for an inline skate, comprising two spaced apart sidewalls connected by an upper horizontal interconnection means, said sidewalls adapted to support a plurality of wheels in an inline configuration, characterized in that the upper horizontal interconnection means comprises three spaced apart web members, and each web member is provided with a respective mounting aperture for securing a boot thereto.

Description

Technical Field

The present invention relates to an inline skate comprising a frame and a boot. In particular it relates to a boot having three mounting points adapted to be mounted to three respective mounting apertures on the frame.

Background

Generally, an inline skate includes a plurality of wheels installed in a frame in series. The frame of an inline skate is designed to be fixed to the lower side of the boots and to support a user's weight. In addition, it is designed to effectively absorb an impact from a contact between the ground and the wheels, and impact due to collision with obstacles when the inline skates are being used. Conventionally, inline skate frames as shown in Figure 4 of WO2004/096385 (Sam Ming CHO ) have a horizontal upper wall interconnecting two side walls which are adapted to support a plurality of wheels in an inline configuration. In recent times attempts have been made to make high speed (or high performance) inline skate frames which are of relatively low mass in which the frame comprises two side support walls that are interconnected and which have two spaced apart mounting points in the form of elongate apertures at raised spaced apart locations. An example of this design is shown in the applicant's own U.S. Design Patent No. 470208 entitled "Inline Skate Frame". In such a frame the boot is mounted to the two spaced apart mounting points.
In recent times larger skating wheels have been introduced and skaters have desired that their boots be as low as possible to the ground. As a result of this, the traditional gap between the two frame mounting points has increased from about 165mm to 195mm. This increase in the distance of the gap allows the boot mounted to such a frame to flex, which is undesirable.
The present invention attempts to overcome at least some of the disadvantages of the prior art inline skate frames.

Summary of the Invention

In accordance with a first aspect the present invention consists of a frame for an inline skate, comprising two spaced apart sidewalls connected by an upper horizontal interconnection means, said sidewalls adapted to support a plurality of wheels in an inline configuration, characterized in that the upper horizontal interconnection means comprises three spaced apart web members, and each web member is provided with a respective mounting aperture for securing a boot thereto.
Preferably, said three spaced apart web members are equally spaced apart.
Preferably, two of said three web members are disposed at or near opposite ends of said frame, and the remaining said web member is disposed there between.

Best Mode of Carrying Out the Invention

Figs. 1 to 3 depicts a frame 10 and boot 20, which in combination form an inline skate in accordance with a first embodiment of the present invention. Frame 10 comprises two spaced apart sidewalls 11 that are connected by upper horizontal interconnection means in the form of three spaced apart web members 12, 12a. The sidewalls 11 in this embodiment are each provided with four inline holes 13 allowing four wheels (not shown) to be mounted to the frame 11 in a conventional manner.
Two of the three spaced apart web members 12 are located near the opposed aft and fore ends of the frame 11, whilst the third central web member 12a is disposed there between. Each of the web members 12 is provided with a mounting aperture 14 in the form of an elongate slot. Each of the elongate slots is disposed lengthwise such that they are substantially at right angles (90°) to the intended line of travel of the wheels (when they are fitted to the frame).
Each of the three web members 12, 12a are at the same height as each other, and connected to the upper edges of the sidewalls 11, so that the web members 12, 12a and their respective mounting apertures 14 are flush with the sidewalls 11. This feature differs from the prior art inline skate frame in US Design 470208, where the mounting apertures are raised above the sidewalls.
The boot 20 has three spaced apart mounting points 21, 21a disposed axially in a heel to toe direction. The mounting points 21, 21a allow the boot 20 to be mounted to frame 10 by fasteners (not shown) passing through apertures 14. The mounting points 21 are located near the opposed heel and toe ends of the boot, whilst mounting point 21a is disposed therebetween.
The boot has two sole regions 22, each disposed between two of the three spaced apart mounting points. Both these sole regions 22 are concavely shaped. When the boot 20 is mounted to the frame 10, each of the concavely shaped sole regions 22 is disposed immediately over a respective wheel 30, such that they act as "wheel arches". As shown in Fig. 3, the upper portion 30a of the two central wheels 30 project through openings between web members 12, 12a, thereby being disposed above the frame 10.
This means that whilst larger skating wheels may be used with frame 11, the boot 20 mounted to frame 10 is disposed as low as possible to the ground when in use. In addition the use of three mounting points 21 secured to the respective spaced apart web members 12 on frame 10 results in the boot 20 becoming stiffer and giving the skater a stronger platform to push off.
It is understood that the above has been given by way of an illustrative embodiment of the invention. All modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope of and ambit of the invention as described herein. For example, in a not shown embodiment the central mounting point 21a on the boot that aligns with the central web member 12a of frame 10 may lie in a plane closes to the top of the boot than the other two "heel" and "toe" mounting points. In such an embodiment a spacer may be fitted between the central web member 12a of frame 10 and the central mounting point 21a of the boot. It should also be understood that in other not shown embodiments spacers of various kinds may be used between any of the mounting points and web members.
Whilst the above described embodiment depicts a frame 10 having two side walls 11, it should be understood that in another not shown embodiment the invention may comprise a frame having a single side wall to which the wheels are connected and three cantilevered (or projecting) members each having a mounting aperture would act as the horizontal interconnection means for securing to a boot.
Also in another not shown embodiment the mount slots or apertures may have a shape and orientation that differ to the slots 14 shown in the above described embodiment.
Furthermore, whist the abovementioned embodiment depicts the boot 20 having concavely shaped sole regions 22, it should be understood that in other not shown embodiments the shape of the sole region may differ.
The term "comprising" (and its grammatical variations) as used herein is used in the inclusive sense of "having" or "including" and not in the exclusive sense of "consisting only of".
