Description

Novel run-up device

Technical Field

The invention relates to the field of sports equipment, in particular to a novel running aid.

Background

The run-up device is track and field run-up equipment and is used in various large track and field events. The run-up device is nailed on the runway, wherein also have long nail and short nail, the long nail is used on the cinder runway under the general condition, and the plastic is just used the short nail. The installation method of the starting device comprises a common method and a stretching method. The "normal style" is usually adopted, and the left support is generally in front of the right support. The front support is arranged at the position of one half foot (about 4045 cm) behind the starting line, and the rear support is separated from the front support by one half foot; the supporting surfaces of the front and rear supports and the ground form angles of 40 degrees, 45 degrees, 70 degrees and 80 degrees respectively; the central axes of the two supports are spaced about 15 cm apart.

In the installation process of the traditional running aid, the nail at the bottom of the running aid is utilized to nail the running aid on the runway, but the installation process is very inconvenient, and the effective fixing nail of the running aid can be fixed on the runway only by means of tools. And because the nail is thrown to the plastic and cinder runway, the length of the nail at the bottom of the run-up is also short, and the nail needs to be configured according to the actual situation during installation, which is very inconvenient. Meanwhile, the front pedal support and the rear pedal support of the running aid are only fixedly sleeved in the clamping grooves on two sides of the fixing plate, and if the fixing plate nail is not firm, the front support and the rear support can shake to influence the start of a sportsman. Simultaneously, simple block cup joints between front and back support and the fixed plate, also can't effectively guarantee that the sportsman does not can make front and back support take place to rock when kicking backward with strength at the in-process of starting off, has certain risk. And when the athlete pedals the front and rear supports with force, the front and rear supports can generate an oblique backward impulsive force, and the front and rear supports do not have good fixed protection at the moment, so that the whole running aid is easy to pedal backward, and danger is caused.

When the push-pull sliding plate 31 moves to the clamping blocks 32 on the two sides of the rear end and is clamped in the third clamping grooves 63, the threaded thin nail 73 is driven to rotate for a large number of turns, the whole threaded section on the threaded thin nail 73 is screwed out of the inner threaded groove on the mounting cylinder 74, the threaded thin nail 73 penetrates out of the bottom surface of the first fixing bottom plate 1 for a long distance, the long nail function is realized, and the device is suitable for a cinder track. When the athlete steps on the front support and the rear support to prepare for starting, the pressure of the legs of the athlete presses the lower pressing rod 81 in the second clamping groove 57 on the second side baffle 51 through the first connecting column 59b, the lower pressing rod 81 pushes the flat harrow 82 to be inclined and supported on the ground along the direction in which the second clamping groove 57 inclines, so that a stable triangle is formed among the foot of the athlete, the flat harrow 82 and the ground, and the supporting plate 52 is more stable and firm when the athlete starts to run by pedaling the rubber pad 54 and the supporting plate 52. Meanwhile, during the running of the athlete kicking off the rubber pad 54 and the supporting plate 52, the pressing-down rod 81 generates a slight upward reaction force in a slant direction due to the reaction force of the fourth spring 84, so as to help the athlete accelerate the running in the case of the athlete kicking off the supporting plate 52 with too much force.
