Description:

BACKGROUND OF THE PRESENT INVENTION

1. Field of Invention

The present invention relates to sportsboard, and more particularly to a sportsboard comprising a locking arrangement which is capable of securely and conveniently locking the sportsboard onto a fixture so as to avoid being stolen.

2. Description of Related Arts

Conventional sportsboard, such as a surfboard, are widely utilized by those who love water sports including the likes of surfing, wake riding, snowboarding, kayaking, and skating. A conventional sportsboard usually comprises a riding board having a predetermined shape which is adapted to fit a predetermined water sports, and a stabilizing device, such as a fin, extended from the riding board for steering, propelling and stabilizing of the sportsboard when it is gliding on a water surface.

Conventional sportsboard has a pressing disadvantage of lacking an effective locking device for locking the sportsboard when it is not in use in order to prevent such undesirable conduct as theft. The underlying difficulty in designing such a locking device lies with its interference with the normal operation of the spbrtsboard. Specifically, any add on locking device is liable to deteriorate the performance of the sportsboard. This perhaps small and insignificant deterioration in performance may become material when it is to be utilized in professional competition in which extremely accurate assessment of performance is required. Thus, a small deterioration in performance may result in material alteration in the ranking in a particular water sports competition.

Obviously, the deterioration in performance is not necessarily material when the sportsboard is utilized only for entertainment purpose. However, it doesn't mean that it poses no problem when the add-on locking device, such as a locking hole drilled on the riding board, affects the stability of the whole sportsboard. As such, it is even unsafe that the sportsboard is to be utilized for water sports.

Even though the locking device does not affect the general stability of the sportsboard, it may present a danger to the user during the course of the water sports. For example, during surfing, the user may unexpectedly encounter an intensely strong wave which brings the user out of the riding board. Normally, the user should be able to swim and grab the riding board so as not to get lost of floating support in the water. However, it is possible that the locking device, due to random motion driven by the strong wave, accidentally hit the user, then, the user may no longer be able to grab the sportsboard tightly and then regain control thereof. In other words, the locking device may pose a danger to the user.

Since the sportsboard is fairly expensive, it is necessary to protect it from being stolen, especially when it is not in use. However, with the above-mentioned problems, conventional locking device seems to provide the locking function at the expense of the quality of performance, which is definitely undesirable. This presents a rather paradoxical dilemma in which two conflicting considerations equally prevail. In view of this, a novel sportsboard with a locking arrangement which is capable of overcoming the above-mentioned difficulties has to be developed.

SUMMARY OF THE PRESENT INVENTION

Another object of the present invention is to provide a sportsboard locking arrangement, which is adapted for use in conjunction with conventional locking devices, such as a regular lock, so that no specifically-designed equipments are needed. In other words, no unnecessary expense will be incurred to the user for buying any specific equipment in using the present invention.

Another object of the present invention is to provide a sportsboard locking arrangement, which is adapted for use effectively in a wide variety of sportsboards so as to generally enhance security for conventional sportsboards.

Another object of the present invention is to provide a sportsboard locking arrangement, which does not alter the original design and structure of the sportsboard, so as to minimize the manufacturing cost and the ultimate selling price of the present invention.

Another object of the present invention is to provide a sportsboard locking arrangement, which is easy and convenient to operate, but provides sound security protection to the sportsboard from theft.

Accordingly, in order to accomplish the above objects, the present invention provides a sportsboard locking arrangement for a sportsboard having a surface and a receiving slot indented thereon, wherein the sportsboard locking arrangement comprises:

    • a locking guider having a guiding member defining a locker guiding hole thereon and two pivot arms downwardly extended from the guiding member wherein a distance between the two pivot arms of the locking guider is smaller than a width of the receiving slot; and
    • means for pivotally mounting the two pivot arms of the locking guider on two sidewalls of the receiving slot, wherein the locking guider is adapted for pivotally moving between a locking position that the guiding member is pivotally folded at a position above the surface of the sportsboard, and a storage position where the guiding member is pivotally folded into the receiving slot below the surface of the sportsboard;
    • whereby, when the locking guider is folded at the locking position, a fastener is adapted to pass through the locker guiding hole of the locking guider to lock up the sportsboard to a fixture.
