Description

Light-operated trampoline

The invention relates to a light-operated trampoline, in particular to a trampoline suitable for human hand-operated bed to open up or down.

In the linkage mechanism of the conventional trampoline, as shown in the first and second figures, an upper strut 93 and a lower fixing rod 92 are respectively connected to the side of the bed board 90 and the bed base 91, and the front height is pivoted therebetween. The short-tilt short connecting rod 94 and the long connecting rod 95 are connected to each other, and the upper pivot rod 96 and the lower pivot shaft 99 are connected between the upper strut 93 and the long connecting rod 95, and the rods are used. The associated fulcrum configuration and the weight of the bed plate 90 allow the bed panel 90 to be attached to the bed base 91.

After the user applies the force to the upper slab plate 90 for a period of time, the long rod 95 can be continuously pushed by the movable rod 97 of the air pressure rod 96, so that the upper rod 93, the short link 94 and the long link 95 are automatically opened. The positioning state shown in the first figure is opened.

The linkage mechanism of the conventional trampoline utilizes the pivot 98 on the upper side of the pneumatic rod 96 to form a larger torque and the output angle. After the user starts to open the bed 90, the pneumatic rod 96 continues to force upward upward. The bed board 90 is positioned. Therefore, when the user wants to start to cover the bed 90 from the top to the bottom, he must first pull down vigorously. The bed board 90, which is sufficient to overcome the lifting force of the air bar 96, begins to swing downward, and finally uses the falling force and speed of the bed 90 to close to the bed base 91. Since the conventional trampoline begins to open and close, it must be manually operated. Therefore, for the elderly and the elderly, it takes a lot of mental and physical strength, which is quite troublesome and inconvenient, and the bed 90 is fast. Danger is likely to occur during opening and closing. Therefore, how to solve the above problems is the subject of research that the relevant industry players are eager to study.
