Title: Protection device for trampoline

Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a protection device for a trampoline wherein the protection device is combined with a trampoline in order to provide safety for a person exercising on the trampoline. 
     Under the trend where a person pays a lot of attention to his/her physical health, exercise machines are quite popular on the market and trampolines are often found in gymnasiums or stadiums. However, those trampolines are not equipped with any protection device. 
     Trampolines are common exercise equipment. However, since a trampoline per se is not equipped with any protection measures, a user is often suffered from injuries caused by falling off the trampoline. Therefore, in the past, a spongy pad is often placed on the periphery of the trampoline to prevent a user from being injured when the user falls off the trampoline. The material of the spongy pad is, however, often liable to degrade due to use and aging and loses its original elasticity and, as a result, causes injuries to a user. Furthermore, a spongy pad is sometimes misplaced by a user when the user falls off a trampoline such that a subsequent user is injured when he/she falls off the trampoline and is not landed on the spongy pad. 
     SUMMARY OF THE INVENTION 
     Based on the above disclosure, an ordinary trampoline is not equipped with a protection device and, therefore, often causes unnecessary injuries to a user. Therefore, the inventor of the present invention performs researches on this problem and develops a trampoline that has not only exercise functions, but also safety features. 
     The main objective of the present invention is to solve the above-mentioned drawbacks and avoid the existence of such drawbacks by combining a protection device with a trampoline thereby providing protection for a user exercising on the trampoline. 
     Detailed explanation and technical contents of the present invention are disclosed hereinafter, together with the figures.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 1 shows a 3-D schematic diagram of the present invention. As shown in FIG. 1, the protection device  1  comprises a predetermined quantity of support parts  11 , the two ends of each support part  11  being separately installed with an annular upper half part  12  and an annular lower half part  13 ; and a protection film  14  being installed between two support parts  11 . wherein, each of the support part  11 , the upper half part  12  and the lower half part  13  are gas-filled bodies. wherein, the upper half part  12  and the lower half part  13  are multilateral bodies. wherein, each of the support part  11 , the upper half part  12  and the lower half part  13  are installed with gas-filling openings  111 ,  121  and  131 . wherein, the protection film  14  between two support parts  11  is installed with a plurality of air permeable openings  141 ; furthermore, one face of the protection film  14  is openable, and the periphery of the openable protection film  14  is installed with an opening and closing element  142 . wherein, the opening and closing element  142  is a slide fastener assembly or a button assembly. wherein, the protection film  14  is made of a transparent material or a non-transparent material. wherein, each of the support part  11 , the upper half part  12  and the lower half part  13  can form an inter-connected state and be inflated through a gas-filling opening. 
     FIG.  2  and FIG. 3 are a schematic diagram for the present invention under use and a schematic diagram of an assembly of the present invention and a trampoline, respectively. As shown in the figures, the protection device  1  is combined with a trampoline  2  by buckling the lower half part  13  with the frame  21  of a trampoline  2  through a predetermined amount of fastening elements  15  to form a trampoline equipped with a protection device  1 . wherein, the fastening element  15  is a Velcro or a male-female buckling element. 
     Therefore, the present invention combines a protection device with a trampoline to provide safety to a user exercising on the trampoline such that the user can exercise on the trampoline in a safe environment and prevent himself/herself from being injured caused by falling off the trampoline. The present invention completely eliminates the conventional drawbacks and endows a trampoline, in addition to exercise functions, with safety features. However, the above-mentioned disclosure is only a preferred embodiment of the present invention, and is not used to limit the scope of the present invention. Any equivalent modification or alteration of the claims of the present invention is within the scope of the present invention.
