This invention broadly relates to a braking system for recreational riding-boards. In particular, the invention relates to a braking system for recreational riding-boards capable of enabling a rider to maintain balanced during braking.
Description of Related Art
It is desirable in the board-riding industry to provide riding-boards that are safe and versatile. One way to achieve this is to provide a braking system which enables the rider to slow down or stop particularly when riding downhill.
Existing braking systems have a shortcoming in that when the brake is applied, the rider is likely to be thrown off balance due to forward momentum. Hence riding-boards equipped with such a braking system are actually more dangerous to ride.
It is an object of the present invention to provide a braking system which is capable of ameliorating or overcoming the above shortcoming or which Will at least provide a useful alternative.
According to one aspect of the present invention there is provided a braking system for a recreational riding-board, the braking system including:
a braking mechanism adapted to slow down or stop the motion of the riding-board; and
an activating means adapted to control the braking mechanism;
wherein the activating means in use is located between the middle and rear end of the riding-board.
In a preferred embodiment, the activating means has a first end adapted in use to be held by a rider and a second end operatively connected to the braking mechanism.
Preferably, the activating means in use in located in the vicinity of the rear end of the riding-board.
In a preferred embodiment, the activating means is removably attached to the riding-board. The activating means may include a pliable tether. When subjected to a pulling force exerted by the rider, the activating means is preferred to be capable of changing from a slack state to a tensioned state.
Preferably, the tensioned activating means is capable of providing the rider with leverage. As such, the tensioned activating means is capable of activating the braking mechanism and bracing the rider against forward momentum simultaneously.
Preferably, the tensioned tether is capable of inhibiting further forward momentum of the rider caused by braking. In a first embodiment, the recreational riding-board is a skateboard. The skateboard includes an aperture. Preferably, the aperture is located toward the rear of the riding-board. The aperture is preferred to provide a fulcrum against which the tether bears.
Preferably, the tether includes a first portion including the first end and being disposed on one side of the skateboard. The first end is preferred to include a handle adapted to facilitate gripping by the rider. The tether is preferred to include second portion including the second end and a third portion including a third end, both of the second and third portions being disposed on an opposing side of the riding-board.
Optionally, the first portion of the tether is covered by a telescopic sheath extending from the upper surface of the skateboard.
Alternatively, the activating means is in the form of a rigid stick, rod or wire.
The braking mechanism may include one or more levers. Preferably, the braking mechanism includes a pair of levers, each being connected to a truck of the skateboard via a pivot hinge. Each of the second and third ends of the tether is connected to one end of a corresponding lever. The other end of each lever is preferred to be attached to a braking means adapted in use to engage a rear wheel of the skateboard. Each braking means may be in the form of a brake pad.
The braking mechanism may include an additional pair of levers for the front wheels of the skateboard. In such an embodiment, the tether includes fourth and fifth portions, each having an end connected to the corresponding additional lever.
Each of the levers may be a cam lever or biased.
In another embodiment, the recreational riding-board includes a snowboard or sandboard. The snowboard or sandboard may include one or more apertures adapted to accommodate the braking mechanism.
The braking mechanism is preferred to include a lever which is tied at one end to the tensioned tether and pivotally hinged toward the rear of the riding-board. The lever is preferred to follow a curve which conforms to a bent end of the riding-board.
Preferably, the lever includes or is connected to a blade at another end, the blade being adapted in use to plough into or through snow or sand. More preferably, the lever is pivotally connected to a holder which is affixed to the snowboard or sandboard.
The braking mechanism is preferred to include an impediment which in combination with the holder is capable of restricting pivotal movement of the lever. As such, the extent to which the blade, ploughs into the snow or sand may be controlled by installation or removal of the impediment. The impediment is preferably in the form of a pin.
In another embodiment, the riding-board has two apertures each in the form of a slot located toward the rear end of the snowboard or sandboard. In this embodiment, the lever is U-shaped having a pair of prongs adapted in use to plough into or through snow or sand. Each prong is preferred to be aligned with the corresponding slot.
Preferably, each prong has one or more fingers adapted to plough into the snow or sand. Optionally, the or each finger is attached to an elongate snowplough or sandplough.
Preferably, the tensioned tether is capable of pivoting the lever from a retracted position where the prongs are not in contact with the snow or sand to a braking position where the prongs are lowered to plough into the snow or sand. The lever may include biasing means such that it is biased back into the retracted position when not in use.
The invention may be better understood from the following non-limiting description of preferred embodiments, in which:
Different embodiments of the braking system of the present invention are intended to be applicable to different recreational riding-boards such as skateboards and snowboards which are illustrated and described herein. However, it should be noted that the braking system of the present invention may be applied to other types of recreational riding-boards such as sandboards. It should also be noted that the braking system of the present invention is retrofittable onto a used riding-board.

The second and third portions 30 and 32 meet at a meeting point 34 and merge to become the first portion 28 which extends through the aperture 24 being exposed on the upper side of the skateboard 10. In use, the aperture 24 provides a fulcrum against which the tether 14 bears.
As best shown in
In use, the tether 14 is generally in a slack state as best shown in
Referring to
It is contemplated that the braking mechanism may have an additional pair of levers for the two front wheels (not shown) of the skateboard 10. In such an embodiment, the tether 14 has fourth and fifth portions, each having an end connected to a corresponding additional lever which is affixed to the front truck.
Also, although not shown in the accompanying drawings, each of the levers may be a cam lever or spring loaded such that once the rider stops exerting a pulling force on the tether 14 via the handle 18, the levers 36 and 38 will pivot back to the original positions thereby effecting disengagement of the brake pads 54 & 56 from the wheels 58 & 60.

Turning now to
In the present embodiment, the braking mechanism has a tether 14A which is tied to a U-shaped lever 74 which is located toward the rear end 72 of the snowboard 66. The lever 74 follows a curve which conforms to the bend toward the rear end 72 of the snowboard 66. The U-shaped lever 74 has a pair of prongs 76 & 78. The middle of each prong 76, 78 is pivotally hinged to the snowboard 66 and spring loaded. As such, when the front end 80 of the lever 74 is lifted from a retracted position by the pulling force exerted by the tensioned tether 14A, the prongs 76 & 78, which are aligned with corresponding slots 68 & 70, are pivoted into a braking position where the prongs are lowered to plough into the snow through the slots 68 & 70. The lever 74 is spring loaded such that it is biased back into the retracted position when the pulling force is no longer exerted by the tether 14.
