Benefits of technology

[0005] For the purpose of overcoming the limitations of the existing skateboard-ramps and providing an assembly skateboard-ramp with new structure, the present invention addresses the main technical issue by dividing the skateboard-ramp into several groups of ramps, which can be assembled to a whole assembly skateboard-ramp. Meanwhile, every group of ramp can be disassembled and inserted to another group so that the volume of the whole ramp will be reduced and thus brings convenience to the delivery. What is more, the ramp can be lengthened by comprising several groups of ramps together to enhance the skater's jump height and prolong the performance time in the air.

Problems solved by technology

A conventional skateboard-ramp is a complete unit, with a big volume, and cannot be contracted and folded, causing inconvenience to packaging and delivery of the ramp.
Moreover, because it is big volume, it is not able to be lengthened, thus limits jump-over height of the skaters, shortens their action time in the air and finally impacts the quality of their performance in the air.

Embodiment Construction

[0025] With reference to the drawings and preferred embodiment, the specific implementation, the structure, the properties and the functions of an assembly type skateboard-ramp according to the present invention are illustrated in detail as follows.

[0026] The skateboard is a sports instrument for exercise and performance that is widely used in skating. Meanwhile, a skateboard-ramp is an instrument that helps skater to perform multiple actions. A skater can jump by means of the skateboard ramp to perform actions, such as somersault and turn over in the air.

[0027] Refer to FIG. 2, 3, 4, and 5, the assembly type skateboard-ramp according to the present invention mainly comprises: skateboard-ramp 1, skateboard-ramp 2, skateboard-ramp 3, skateboard-ramp 4, etc. At both ends of ramp 1, 2, 3, and 4, there are swallow-tailed grooves 11, 21, 31 and 41 and swallow-tailed tongues 12, 22, 32, and 42. Each ramp has similar shape, but in gradually decreased size (shown in drawing 3, 4, and 5). ...

Abstract

An assembly type skateboard-ramp includes several groups of ramp, two sides of which have swallow-tailed tongue and groove joints respectively. The ramp has a curve face and an opposite vertical face. Each group of ramps has same form and gradually decreased size. The swallow-tailed tongues of ramps of a group are inserted in corresponding swallow-tailed grooves of ramps of another group. These skateboard-ramps can be assembled and disassembled.

Description

FIELD OF THE INVENTION [0001] The present invention relates to an instrument that is used in sports for the purpose of physical exercises and, more particularly, to an assembly type skateboard-ramp. BACKGROUND OF THE INVENTION [0002] A conventional skateboard-ramp is a complete unit, with a big volume, and cannot be contracted and folded, causing inconvenience to packaging and delivery of the ramp. Moreover, because it is big volume, it is not able to be lengthened, thus limits jump-over height of the skaters, shortens their action time in the air and finally impacts the quality of their performance in the air. [0003] Therefore the forementioned skateboard-ramp has a number of disadvantages and needs to be improved. [0004] In order to get rid of the forementioned disadvantages, the inventor, based on his rich experience and expertise, has conducted research and innovation, by means of continuous study and design, and repeatedly making samples and modifying them, finally brought abou...
