Abstract
The utility model belongs to the technical field of sports equipment, and particularly relates to parallel bars suitable for practicing forward rolls. The parallel bars comprise two cross bars (1) and vertical bars (2) positioned below the cross bars (1); each vertical bar (2) is fixedly provided with a connecting piece (3); each connecting piece (3) is movably connected with a crank arm lever (4) through a pin roll (5); each crank arm lever (4) is V-shaped; one side of each crank arm lever (4) is positioned between the two cross bars (1), and the other side of each crank arm lever (4) is positioned outside the two cross bars (1); the two cross bars (1) are provided with a plurality of hooks (6) in a split manner; a protection net (7) is arranged among the hooks (6). Through the crank arm levers, a beginner can feel force application opportunity and force application directions at different periods so as to quickly grasp the technical main points of actions, so that the human safety of the beginner can be effectively protected while the workload of teachers is reduced.
Description
Technical field
The utility model belongs to sports apparatus technical field, particularly a kind of parallel bars of applicable exercise forward roll.
Background technology
Parallel bars forward roll is one of gymnasium apparatus difficult part, and practitioner's fitness, space-time sense and will and character are had to certain requirement.Mainly in teaching adopt other people to help the mode with protection, mainly rely on practitioner's self specific physical quality, action comprehension ability and fixing exercise-equipment to carry out that repetitive learning many times grasps.In parallel bars forward roll teaching, practitioner often can not correctly exert oneself, and causes cannot carrying stern, turning over stern, finally under protection aid's power-assisted, twists over reluctantly.Student's (comprising most of schoolgirl) that some specific physical qualities are weak, first class hour, the difficulty of minute shoulder was also non-general except not completing upset, due to can not and as easy as rolling off a log the falling from the bar of time-division shoulder land, this situation is called leaks shoulder.The mode of this outer portion power-assisted comes the efficiency of execution study and exercise consciousness, enthusiasm obviously not ideal enough, and the sponge-rubber pad of pendulum bulk under thick stick and frame clumsy skill pad on thick stick has just become practitioner's " help symbol ".
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of parallel bars of applicable exercise forward roll are provided, and these parallel bars can make practitioner rely on the strength of self just can complete and carry stern, turn over stern action, and can reduce the generation of leaking shoulder phenomenon.
To achieve these goals, the technical solution of the utility model is as follows: a kind of parallel bars of applicable exercise forward roll, comprise 2 cross bars and be positioned at the montant under cross bar, on described montant, be fixed with connector, on connector, by bearing pin, be connected with curved arm lever, curved arm lever is " V " font, and a side of curved arm lever is between 2 cross bars, and the opposite side of curved arm lever is positioned at outside 2 cross bars.
Practitioner's lean forward from the waist item arm bar part between 2 cross bars of buckling while declining of crooking one's arm, being positioned at 2 parts outside cross bar holds up lower limb, make practitioner rely on apparatus to rely on the strength of self just can complete and carry stern, turn over stern action, without other people power-assisted, save human resources.On the other hand, one side of curved arm lever is between 2 cross bars, the opposite side of curved arm lever is positioned at outside 2 cross bars, the bottom of " V " font can be blocked by cross bar in uphill process, now the part between 2 cross bars of curved arm lever just drops to the position parallel with thick stick face, this scheme has effectively increased shoulder support face, avoids the Lou generation of shoulder peril.When practitioner grasps after the essential of exercise of forward roll substantially, connector and curved arm lever can be unloaded from parallel bars, parallel bars revert to appearance of the prior art.
As further technical scheme, described curved arm lever is longer than and is positioned at 2 parts outside cross bar in the part between 2 cross bars.
This scheme makes curved arm lever become laborsaving lever, makes practitioner spend less strength its lower limb can be held up.
As further technical scheme, described connector comprises 2 intermediate plates, and intermediate plate is adjusted the distance between 2 intermediate plates by the bolt in intermediate plate end, and connector has a planar portions, and described bearing pin is connected in planar portions.
This scheme provides a kind of fastening effective and easy-off connector.
As further technical scheme, split typely on described 2 cross bars be provided with some hooks, between hook, there is catch net.
As technical scheme further, the position of described catch net is near described curved arm lever.
Catch net can prevent that beginner from completing landing from parallel bars after forward roll, waits after skilled and catch net can be taken off from parallel bars.
In sum; the utlity model has advantage rational in infrastructure, successful; by curved arm lever, make beginner can know from experience the opportunity of having an effect and the power thrusts of different phase, comparatively fast to grasp stroking technique main points, when reducing teacher workload, can effectively protect beginner's personal safety.

The specific embodiment
Embodiment 1
As shown in Figure 1, a kind of parallel bars of applicable exercise forward roll, comprise 2 cross bars 1 and be positioned at the montant 2 under cross bar 1, on montant 2, be fixed with connector 3, on connector 3, by bearing pin 5, be connected with curved arm lever 4, curved arm lever 4 is " V " font, and a side of curved arm lever 4 is between 2 cross bars 1, the opposite side of curved arm lever 4 is positioned at outside 2 cross bars 1, and curved arm lever 4 is longer than and is positioned at 2 parts outside cross bar 1 in the part between 2 cross bars 1.Split typely on 2 cross bars 1 be provided with some hooks 6, between hook 6, have catch net 7, catch net 7 is made by elastic string, and the position of catch net 7 is near curved arm lever 4.
As shown in Figure 2, connector 3 comprises that 31,2 intermediate plates 31 of 2 intermediate plates are used for clamping montant 2.The distance that intermediate plate 31 is adjusted between 2 intermediate plates 31 by the bolt 32 in intermediate plate 31 ends, connector 3 has a planar portions 33, and bearing pin 5 is connected in planar portions 33.
When beginner rests in after the forward roll essential of exercise in parallel bars, connector 3, curved arm lever 4, hook 6, catch net 7 can be taken off from parallel bars, parallel bars revert to the appearance of prior art.
