Abstract

A ramp for use with a sport bicycle comprises a top plate 1 connected to a base 7 by means of a spring 5 which has a shock absorbing function thereby giving the cyclist bounce and flexibility and has two anchor plates 9 in front for anchorage and sturdiness. <IMAGE>

Description

SPECIFICATION Steel ramp with spring attachment for sport bicycle Background of the invention Field of the invention: The invention relates to a ramp for sport bicycle comprising use of a spring to give bounce and flexibility as well as being portable and folding flat compared to the original model which was previously a simple design with none of the above new features.

Description of the prior art It is a known fact that past and current ramp designs are all simple designs and of a rigid type and non collapsable product. It has no spring action and the ramps have a tendency to dangerously slide on impact having no anchorage into the ground and capable of causing injury to the cyclist.

They are poorly visible from a distance as they are made of wood which is not portable and after a short period begin to splinter and break causing the sport of ramping to become hazardous.

Summary of the invention In the prior art, a ramp for sport bicycle is a simple structure made of wood which is not of great appeal to a young cyclist wanting to use his bicycle in the same way as is done at the sport bicycle track where in most cases if not all cases these tracks are closed during the week and only open on the weekend. The cyclist therefore substitutes the track for the public sidewalk, kerb or the road and even public open parking areas endangering lives in the process. In accordance with the subject invention, the ramp is able to provide all the fun of the track with the spring which is attached to the spring lock at the top and to the spring guide at the base.It has great shelf appeal as it has two brightly painted broad edges and has stickers affixed to it indicating the pressure point area as well as the Model number and name of the ramp adding to the appearance of the product. As the ramp is portable the young cyclist will be able to transport his ramp to safe areas for ramping as well as being able to transport it to his friends homes where children can enjoy themselves together or if so desired alone.

It is a prime object of the present invention to manufacture the ramp from light gauge sheet steel making it easily portable and also compact as the ramp folds flat. As an added safety factor, the edges of the ramp are painted in a bright colour affording the cyclist good visibility and is equipped with two anchor plates in front which holds the ramp, firmly embedding the plates into the surface.

This also stabilises the ramp preventing it from falling over should the cyclist ramp slightly offcentre.

More particularly the object of the ramp is to provide the young cyclist with a product which will permit him to enjoy his sport to the full, as if he were cycling at a sport track.

It is another object of the invention to keep young cyclists away from motorists and pedestrians as they tend to cycle in the road or on the sidewaks or ramp off the kerb and at the same time trying to perform different stunts. Our product will offer all the enjoyment and at the same time away from these danger areas, where such stunts can be performed in the privacy of the garden or any open ground. Our model is specifically designed for use on soft ground such as on grass sand or on far.

Other objects and advantages of the invention will become appearent during a reading of the specification taken in connection with the accompanying drawings.

Brief description of the drawings Figure 1 is a side view of the ramp showing the spring attached at the top to the spring lock and at the bottom to the spring guide as well as showing the anchor plate and split pin and washer; Figure 2 is the rear view of the spring ramp showing both anchor plates as well as the spring attached to the spring lock and spring guide; Figure 3 is the top view of the ramp which is smooth-top finished with the invisible base folded flat inside the top section together with the spring as it appears when closed; and Figure 4 is the exploded view of the ramp.

Description of the preferred embodiment Referring to the drawings, reference character 1 designates the top plate of the ramp onto which surface the cyclist will ramp and the surface is smooth finished with a safety color code, a spring lock 2 which secures the spring 5 to the top plate 1 of the ramp, the split pin 3 which secures the shaft 6 at both ends, the two washers 4 which aliow for easier collapsability when folding the ramp closed, the coil spring 5 which provides for flexibility and absorbs shock as well as giving bounce, the shaft 6 which allows for easier collapsability, the base 7 of the ramp supports the top plate 1 through the spring 5 and is made up of three pieces of tubing welded together to form the U-shaped base 7 as depictd in the diagram, the spring guide 8 is welded to the centre piece of steel which is welded between the two sides of the tubing at the base 7 and supports the spring guide 8, which in turn secures the spring 5 at the base 7, the anchor plates 9 are placed in front of the tubing at the base 7 to prohibit any movement of the ramp on impact thereby creating a stable structure which will not fall over if ramping off-centre.

It is to be understood that the present disclosure relates to a preferred embodiment of the invention which is for purposes of illustration only and is not to be construed as limiting the invention.
