Description

The invention relates to training devices and can be used to train martial arts athletes, track and field athletes and representatives of other sports that require training in reaction speed, in particular, impact speed.

A device for measuring the characteristics of a strike with a baseball bat is known, which comprises a frame, on the opposite sides of which light sources and receivers are mounted that are electrically connected to a recording device, and which makes it possible to measure, in particular, the speed of the strike with a baseball bat. Measurement of the impact velocity in this device is carried out by measuring the time the bat crossed the rays from the sources to the light receivers, followed by converting this time to a value equal to the velocity of the impact.

However, due to the highly specialized nature of this device, it can only be used to measure the speed of impact with a bat, which makes it impossible to train all the shock parts of the body, arm, leg, fist, knee, elbow. heads.

The problem to which the invention is directed is to provide a compact device in which the impact speed of all impact parts could be measured by a non-contact method.

The inventive device for measuring impact velocity comprises a frame, on the opposite lateral sides of which light sources and receivers are mounted, which are electrically connected to a recording device.

The device has the following distinctive features.

The frame can be arbitrarily located in space, which makes it possible to train all the shock parts of the body.

The named general solution, i.e. arbitrary arrangement of the frame in space, implemented in two versions: by executing the frame in a 0-shaped and U-shaped form.

In the first embodiment, the frame is made 0-shaped, a target is mounted between the shoulders of the frame, and the frame has the ability to be fixed on a mannequin, pear and other surface, which allows it to be placed to practice impacts in separate sections, for example, a mannequin, with all impact parts. Using multiple frames at the same time allows you to measure the speed of each hit from a series of hits.

In another embodiment, the frame is made U-shaped and has the ability to change the height and orientation relative to the support element mounted on the floor or

another surface. This does not require a mannequin, punching bag, etc., and the arbitrary arrangement of the frame in space makes it possible to train all the shock parts. Light sources and receivers may be

0 are installed with the possibility of rotation, which simplifies the selection of the direction of the training impact and at the same time provides automatic adjustment when changing the direction of the impact during training.

5 A target is mounted between the shoulders of the frames,

for example, in the form of a stretch of elastic rubber or an elastically fixed rod, the impact on which the athlete strives to develop the highest speed, which allows accurate concentration of the impact.

The device can be implemented as follows.

In FIG. 1 shows a device with a 0-shaped frame, in FIG. 2nd figurative

5 frames.

On opposite sides of the 0-shaped frame 1, light sources (not shown) and light receivers 2, 3 are electrically connected to the recording

0 with a device 4. A target 5 is installed between the shoulders of frame 1. The frame can be mounted on a pear, mannequin, etc. using the lock 6.

The device operates as follows.

By fixing frame 1 on the mannequin, pear, etc. using the lock 6, strike the target 5. In this case, the shock part sequentially crosses the rays of light coming from

0 sources to light receivers. In the recording device 4, the intersection time of these rays is measured and the inverse value corresponding to the speed of striking by this time.

5 in a variant of the device with a U-shaped

frame see fig. 2, on opposite sides of the U-shaped frame 7, light sources (not shown) and light receivers 8, 9 electrically connected to the recording device 10 are mounted rotatably with respect to the axis OiO 1 1. The frame 7 is fixed on the support element 11 with a screw 12 on the required height and has the ability to rotate 5 relative to the horizontal axis 00. A target 13 is mounted between the shoulders of the frame 7. The light sources and receivers are connected using a U-shaped element 14.

The device operates as follows

Positioning the frame 7 at the desired height and fixing it with the screw 12, orienting it to the required rotation angle with respect to the axis 00, a strike is applied to the target 13. In this case, the shock part sequentially crosses the rays of light coming from sources to light receivers. In the recording device 10, the intersection time of these rays is measured and the inverse to this time value corresponding to the speed of striking.
