Description

The utility model relates to the design of targets for sports and practical shooting and can be used in the manufacture of targets intended for practical shooting competitions, in which athletes use pneumatic weapons in training and competition processes, using plastic balls with a diameter of 6 mm as a projectile.

Various versions of sports targets are known from the prior art, for example, from the source CN 216049457 U, published on March 15, 2022, a target made of a steel plate in the shape of a windmill is known, which contains a base, a support, a rotating disk, a rotating arm and a target head. The lower end of the support is attached to the base, the rotating disk is located on the upper end of the support, the side surface of the middle of the rotating disk is fixed to the rotating shaft, and the rotating shaft is rotatably connected to the support. The rotating arm is located on the edge of the rotating disc, one end of the rotating arm is fixedly connected to the rotating disc. The target head is located at the other end of the rotating arm. The target head movable arm is located on the target head, the target head movable arm and the target head are secured in the clamping groove of the movable arm by one end of a compression spring, which is secured in the rotary arm shaft sleeve by a pin shaft and a cotter pin. The five groups of target heads are designed in the form of a windmill, in which the target heads are distributed in a uniform manner, so that uneven rotation or swinging of a plurality of targets in the same direction can be realized.

This source of information was taken as the closest analogue to the declared utility model.

The disadvantage of the closest analogue is the insufficient reliability of fastening the plates on the levers, and, as a consequence, the possibility of involuntary release of the plates.

Thus, the objective of the claimed utility model is to eliminate the shortcomings of the prior art.

The technical result, which the claimed utility model is aimed at achieving, is to increase the reliability of fixation of the plate at any speed of rotation of the target with its guaranteed detachment when hit by a projectile, with the absence of false alarms.

When developing the claimed utility model, the needs of the target audience of potential target users were taken into account, and work was also done to directly adapt the design for full use with airsoft weapons used in training and competitive processes.

Protection against false alarms is necessary for the full use of the target installation in competitive processes and as an element for creating a target environment at competitions of any level. The installations used must be reliable and repeatable in operation, and in the long term. Without the implementation of this protection, some athletes may gain an advantage due to incorrect operation of the installation, or may be directed by the judge to “overshoot” the exercise, which has a detrimental effect on the emotional state of the athlete.

The claimed technical result is fully achieved by the set of features stated in the independent claim of the formula.

A rotating sports target contains a central body with a rotation bearing installed in it, brackets with holes extending from the central body in one plane in radial directions, locks located at the ends of the brackets opposite to the central body, and metal plates secured in the locks. The plates contain the target and fastening parts. The fastening part of the plate contains a fastener having a round shape and a tapering part tapering towards the fastener, and the lock contains a recess corresponding in shape to the fastening part of the plate. In the recess of the lock in the middle part corresponding to the fastening of the plate, a cylindrical magnet is installed in the same plane with the bottom of the recess, and at the maximum distance from the tapering part of the recess of the lock, in the round part of the recess of the lock there is also an additional cylindrical magnet, which is recessed into the lock.

An additional cylindrical magnet is recessed into the lock body by 0.7 mm.

The brackets diverge from the central body evenly at the same angle.

When installing the plate into the recess of the lock, a gap of 0.1 mm is maintained around the perimeter of the fastening part of the plate.

Further, the claimed utility model is illustrated in more detail by drawings, in which:

Figure 1 shows the rear view of the claimed target,

Figure 2 shows the claimed target in front view,

Figure 3 shows the mounting location of the plate on the lever,

Figure 4 shows a plate

Figure 5 shows the moment of fixing the plate on the bracket,

Figure 6 shows the mounting unit for the plate on the bracket.

The claimed target contains a central body (3) in which a rotation bearing (4) is installed, mounted on a holder (not shown in the figure). Brackets (5) diverge from the central body (3) in the radial direction in one plane, made with through holes (6) for ease. Moreover, the brackets (5) diverge from the central body (3) evenly around the circumference with the same angle between them. At the end of each bracket remote from the central body (3) there are locks (7) in which the plates (8) are secured.

All plates are flat, identical and made of metal.

The plate (8) contains the affected part (9), made round, and the fastening part (10), extending from the affected part (9) in the same plane. The fastening part (10) is a tapered part (11) and a round fastener (12). The tapering part (11) is located tapering from the affected part (9) to the fastener (12).

The lock (7) of each bracket (5) contains a recess (13) in the front view, having a shape corresponding to the shape (fastener and tapered part) of the fastening part (9) of the plate (8). In this case, the recess has such dimensions that the fastening part (10) of the plate (8) placed in it has a gap. In the recess (13) of the lock (7) at the intended location of the connection of the tapering part (11) and the fastener (12) of the fastening part (10) of the plate (8), cylindrical additional recesses (14) are made, designed to prevent jamming when the plate is unfastened and easier release of fasteners from the lock.

In the middle of the round part of the recess (13) of the lock (7) there is a main cylindrical magnet (1) in the same plane with the bottom of the recess (13) (when installing the plate, the magnet (1) is adjacent to the fastening part (10)), and at the maximum distance from the tapering part of the recess (13) in the round part there is also an additional cylindrical magnet (2), which is recessed into the lock (7), approximately 0.7 mm (when installing the plate, the magnet (2) is located at a distance from the fastening part (10)) .

Each of the magnets (1) and (2) performs its own function:

The magnet (1) is located at a distance from the bottom of the recess, so as to directly adjoin the metal surface of the fastening part (10) and performs the function of directly fixing the plate in the lock and ensuring guaranteed operation or “unfastening” when the projectile hits the affected part of the target.

The magnet (2) is located at the maximum distance from the center of gravity of the plate, to counteract the forces that arise when hitting the target installation itself (central body, bracket, lock), and not into the affected part of the plate, in order to avoid false positives. In this scenario, the vectors of forces acting on the plate are in the opposite direction to the vectors of forces acting on the targeted destruction of the plate. Thanks to the action of the levers in this system, protection against false alarms is provided.

It is worth paying attention to the fact that the magnet (2) is not directly adjacent to the metal surface of the plate, but is “recessed” into the seat in a recess to a depth of 0.7 mm. This decision was made due to the repeated superiority of the holding force of the magnet in relation to the mass of the plate itself. Experimental tests have shown that if the impulse is insufficient, the plate can come unfastened from the magnet (1), but still be fixed to the magnet (2).

Fastening and holding the plate is carried out thanks to the implementation of a "Puzzle" type locking connection between the recess of the lock and the fastening part of the plate.

The height of the mounting part of the plate is 38 mm, and the height of the affected part is 70 mm.

When placing the fastening part of the plate in the recess of the lock, a gap of 0.1 mm is formed around the perimeter of the fastening part of the plate.

The developed type of fastening allows you to reliably hold the plate at any speed of rotation of the target, as well as in any initial position, under the influence of different directions of gravitational force vectors. The form of fastening implies a maximum reduction in the static friction force for any displacement of the fastener in the seat within the established gaps due to the geometry of the lock.

Let's consider two cases:

1. The plate is fixed in the lock, the affected part is directed upward. Under the influence of gravity, the plate will tend to move to the lower position in the lock until it reaches the lock. Geometrically, this case can be considered as the contact of the outer surface of a cylindrical body, with a diameter of 19.8 mm, with the inner cylindrical surface of the fastening, with a diameter of 20.0 mm, where the place of contact of the bodies will be one line (in the projection - point (15)) (see Fig. 6).

2. The plate is fixed in the lock, the affected part is directed downwards. Under the influence of gravitational forces, the plate will tend to move to the upper position in the lock until it reaches the junction with the lock. Geometrically, this case can be considered as the contact of the outer surface of a cylindrical body, with a diameter of 19.8 mm, with the inner truncated cylindrical surface of the fastening, with a diameter of 20.0 mm, where the place of contact of the bodies will represent two lines (in the projection - points (16)) (see Fig. .6).

Thus, the above target design fully ensures the achievement of the stated technical result.

The claimed utility model is new, since the totality of its essential features is not known from the prior art, and, accordingly, meets the patentability condition of “novelty”.

The claimed utility model meets the patentability requirement of “industrial applicability”, since it can be used in industry.

Although the present utility model has been disclosed with reference to preferred embodiments thereof, this is not intended to limit the present utility model, those skilled in the art may modify and implement the present utility model without departing from the spirit and scope of the utility model, therefore , the scope of protection of a real utility model should be regulated by the scope specified in the formula of the utility model.
