Trampoline structure
Technical field
The present invention relates to a kind of trampoline structure, particularly relate to a kind of trampoline structure with the resistance to degree of high use.
Background technology
After the material life of modern is plentiful gradually, start the activity focusing on the lifting qualities of the life such as leisure, motion.Especially modern's amount of exercise is not enough, space is limited, and therefore various sports equipment manufacturing technology constantly progresses greatly, to providing the sports equipment little, easy to use that takes up room.
Trampoline in known technology is as United States Patent (USP) the 7th, and shown in 766, No. 795, a trampoline comprises ring-shaped frame (circular frame), and this ring-shaped frame is propped up by multiple feet (legs).This ring-shaped frame connects a spring pad (mat) by multiple spring (spring member), one annular wall (cylindrical wall) is installed on this framework, this annular wall is essentially flexible network structure, is dished out outside trampoline by the elastic force of trampoline for preventing user.When user jumps on this spring pad, the weight of user and this spring pad can stretch described spring, and the other end of described spring is linked to this ring-shaped frame, therefore the stressed meeting of described spring is transferred to this ring-shaped frame.Therefore, in use, the supporting framework of trampoline, comprises ring-shaped frame and feet, needs to bear sizable pressure.
The pressure that this spring produces this ring-shaped frame is described for convenience of description, referring again to No. 2010/0273611, another US Patent No., this front invention discloses a kind of trampoline, discloses the annexation of this spring (spring) and this ring-shaped frame (frame) in Fig. 3 of US No. 2010/0273611 patent.Obviously visible in figure, this spring one end is buckled on this ring-shaped frame, and the position of its snapping is about the inclined inner side, top of this ring-shaped frame.Can be gently intelligible, when user bounces on this trampoline, this spring will pull this ring-shaped frame, the strength that spring is pullled can be divided into horizontal component and vertical stress component with the angle of mechanics.Because the spring pad of this trampoline is because the weight of user is to sinking, this spring will be far longer than horizontal component to the vertical stress component that this ring-shaped frame applies, also namely, this ring-shaped frame is except the strength pullled to the inside, and this ring-shaped frame also receives very large pressure at right angle.
In theory, although circular tube shaped framework can be cancelled out each other when being subject to multidirectional stress, and circular pipe type framework has production cost advantage low, easy to assembly.But the study and use experience of circular pipe type framework is pointed out, this spring is unidirectional to the strength that this ring-shaped frame applies, spring apply pulling force in the position of this circular pipe type framework, direction is fixing, circular tube shaped framework effectively cannot be offset or be disperseed born stress.Therefore under Long-Time Service, skeleton joint easily because of user bounce produce pressure and be out of shape.Especially be the upper and lower of pipe, under spring is to the pullling of framework, bears larger stress.Larger problem is, because aforesaid ring-shaped frame is connected by multiple body to forming, in body joint be most fragile, meet with stresses maximum place, can be out of shape and produce the problem of security deficiency under Long-Time Service.
In front invention known now, most trampoline is still and uses circular tube shaped framework, except aforesaid US Patent No. 7,766, No. 795, No. 2010/0273611, US invention beyond, many the known patent such as No. 7,854,687, US2010/0311545, US, No. 2010/0190608, US, No. CN2571421st, Chinese patent are also had to disclose the trampoline using circular tube shaped framework.
Except circular tube shaped framework, in order to strengthen physical strength, also has the frame figure of other changes, as shown in No. 2010/0240496, US Patent No..Visible in Fig. 3 of this front invention, in order to strengthen the ability to bear to vertical stress component, it is flat face that upper and lower surface is changed in the body of formation framework and body joint, connects between upper and lower two flat faces with cambered surface, in the quadrilateral shape of distortion as same athletic tracks.By this upper surface, and the support of this cambered surface, really can strengthen its physical strength.
But, in order to extend trampoline service life, and guarantee the safety of user when using trampoline, the structural design of this ring-shaped frame still needs further reinforcement, therefore the present invention proposes the framework that another kind has more outstanding physical strength, especially do the change of form in body joint, in the hope of body joint, there is enough intensity and meet with stresses, and guarantee to be connected closely between body, to extend trampoline service life.
