Description

The utility model relates to batons and can mainly be used by police and law enforcement officers to defend themselves when attackers violate or restore order. In addition, the proposed design can be used in game sports in which striking is required - baseball, cricket, bast shoes, hockey, polo.

Known telescopic baton with variable weight, which can be used by law enforcement officials or for self-defense (US 7044858 [1]). The baton contains a handle and a folding hollow body of several sections. When transporting or wearing, all sections are shifted to the handle and extend when brought into operation. The end section provides for the placement of one or more weights, spring-loaded to the end of the working end. By varying the number of weights, you can change the weight of the baton. According to the authors, this provides an increase in the effectiveness of the baton (inflicting maximum damage) with the same kinetic energy of the baton that the user gives it. A disadvantage of the known design is the need for significant muscular strength to strike at high speed with the baton. This is due to the fact that during the strike, the end of the baton describes an arc and the centrifugal force F equal to F = mv2 / R acts on the weights, here m is the mass of the weight, v is the speed of the baton R is the radius of curvature of the trajectory of the baton. It is clear that the impact force in this case is limited by the user's power.

A baton is known, containing a handle with a hand protecting ring, forming together with the working part a common hollow body, inside which a moving mass in the form of sand or liquid is placed (CN 201016644 [2]). At the time of the swing, the mass is in the handle and does not affect the acceleration of the baton at the beginning of the strike, but moving under the influence of centrifugal force to the end part of the body allows, according to the author, to increase the force of the blow. A disadvantage of the known device is the use as a moving mass of sand or liquid, as well as those inherent in the previous device described above. In the process of striking, the end of the baton describes the arc and the centrifugal force F equal to F = mv2 / R acts on the weights, here m is the mass of the weight, v is the speed of the baton R is the radius of curvature of the trajectory of the baton and the impact force in this case is limited by the user's power.

A baton is known that contains a handle and a housing connected to it, inside of which, in the hollow distal end, a moving mass in the form of a metal fraction is placed (US 2002155894 [3]). The presence of this mass allows you to extend the contact time with the site of the strike, which increases the effect on the muscles of the intruder, which hit and prevent the rebound of the club. A disadvantage of the known device is, as mentioned earlier, that the impact force is limited by the power of the user.

Closest to the claimed is a baton known from the description to US 2008234053 [4]. The baton consists of several hollow sections connected by carving, in each of which, except for the first, a spring-loaded weight of a cylindrical shape can be placed. By varying the number of sections, you can change the working length of the baton, and by changing the number of weights from one to several, you can change the weight of the baton. Moreover, to change the speed of the rotational movement of the baton, weights can be installed either closer to the handle or closer to the distal end. If it is desirable to increase the speed of striking, then weights are installed in sections closer to the handle. If it is desirable to increase the force of impact, then the weights are placed in sections of the striking end of the baton.

A disadvantage of the known design of the baton is that it does not allow you to change the speed of striking directly at the time of its implementation. To change the speed, you need to disassemble the baton, spinning it into sections and change the location of the sections with weights.

The inventive club is aimed at providing the possibility of changing the speed of striking directly at the time of its implementation due to the supply of energy from an additional source.

The specified result is achieved in that the baton contains a handle and a hollow body connected to it, inside of which a weight is placed. In this case, the weight is equipped with a means of its forced movement to the handle, equipped with a means of enabling movement and means of returning the weight to its original state.

This result is also achieved by the fact that the means for moving the weight to the handle is made in the form of a spiral spring connected to it, located in the handle, and the means for switching on the movement in the form of a lever releasing a spiral spring stretched in the handle.

The indicated result is also achieved by the fact that the means of returning the weight to its initial state is made in the form of a spiral spring connected to it, the second end of which is fixed to the end of the hollow body of the baton.

The indicated result is also achieved by the fact that the means of shifting the weight to the handle is made in the form of an electromagnetic relay core connected to it, placed together with the current source in the handle, and the means of switching movement in the form of a switch installed between the electromagnetic relay and the current source in the handle.

The indicated result is also achieved by the fact that the weight is made in the form of a core of a solenoid placed in a hollow body, and the means for switching on movement in the form of a switch installed between the solenoid and the current source in the handle.

Distinctive features of the claimed batons are:

- the weight is equipped with a means of its forced movement to the handle;

- the means of its forced movement to the handle is equipped with a means of enabling movement;

- The baton is equipped with a means of returning the weight to its original state;

- the means of moving the weight to the handle is made in the form of a spiral spring connected to it, located in the handle, and the means for switching on the movement in the form of a lever releasing a spiral spring stretched in the handle;

- the means for returning the weight to its initial state is made in the form of a spiral spring connected to it, the second end of which is fixed to the end of the hollow body of the baton;

- the means of shifting the weight to the handle is made in the form of an electromagnetic relay core connected to it, placed together with the current source in the handle, and the means for switching movement in the form of a switch installed between the electromagnetic relay and the current source in the handle;

- the weight is made in the form of a core of a solenoid placed in a hollow body, and the means for switching on movement in the form of a switch installed between the solenoid and the current source in the handle.

Providing the weight with a means of moving it to the handle and turning it on at the right time allows the weights to move to the handle of the baton, which will reduce the moment of inertia of the baton and thereby increase the speed of the end of the baton. This obviously follows from the law of change in the moment of momentum of a rigid body (see LD Landau, EE Livshits "Theoretical Mechanics"):

- момент силы, в нашем случае с которой пользователь действует на дубинку, Y - момент инерции дубинки,

- угловое ускорение конца дубинки. Для каждого конкретного пользователя

= const, таким образом, уменьшая Y в процессе разгона дубинки можно увеличить

и соответственно, скорость дубинки. Перемещение грузиков к ручке дубинки во время разгона, как раз и приводит к уменьшению Y, т.к. Y~m R2, где m - масса дубинки, R - расстояние от центра масс до кончика ручки, которое уменьшается при движении грузика к ручке. Снабжение грузика средством его перемещения к концу дубинки позволяет вернуть грузик к концу дубинки после совершения удара или при необходимости утяжелить конец.here

is the moment of force, in our case with which the user acts on the baton, Y is the moment of inertia of the baton,

- angular acceleration of the end of the baton. For each specific user

= const, thus, decreasing Y during acceleration of the baton can increase

and accordingly, the speed of the baton. Moving the weights to the handle of the baton during acceleration, just leads to a decrease in Y, because Y ~ m R2, where m is the mass of the baton, R is the distance from the center of mass to the tip of the handle, which decreases as the weight moves to the handle. Providing the weight with a means of moving it to the end of the baton allows you to return the weight to the end of the baton after a strike or, if necessary, weight the end.

The effect of using a baton can be explained not only from the point of view of mechanics, but also from the point of view of the law of conservation of energy. At the moment of acceleration of the baton, the centrifugal force F acts on the weight inside the baton

here m _gr is the mass of the weight, V is the speed of the baton, r is the radius of curvature of the trajectory of the baton. A pre-stretched spring or a solenoid, when voltage is applied to it, produces work A against centrifugal force to move the weight over distance S towards the handle of the baton

According to the law of conservation of energy, this energy passes into the additional kinetic energy of the club.

where m is the mass of the baton, ΔV is the increment of speed. Moreover, this additional energy is equal to

where P is the power of the energy source (a pre-stretched spring or a solenoid with a battery), Δt is the acceleration time of the baton, that is:

Given reasonable parameters: m _gr = 0.1 kg; V = 10 meters per second; r = 1 meter; S = 0.05 meters; m = 0.5 kg; Δt = 0.1 sec. it is easy to see that with these parameters the speed of the baton increases by about 20% at very low values of power consumption, on the order of tens of watts.

Means for shifting the weight to the handle can be made in various ways. For example, in special cases, it can be in the form of a spiral spring connected directly to it or by means of a rod, placed in the handle or in the form of an electromagnetic relay connected directly to the weight or by means of a rod, placed together with a current source in the handle. Accordingly, the means initiating the movement of the weight to the handle can be made in the form of a lever releasing a spiral spring stretched in the handle or in the form of a switch mounted between an electromagnetic relay and a current source in the handle. Also, a means of moving the weight to its original state (towards the end of the baton) can be performed in various ways. It can be spiral springs, rubber bands, cores of electromagnetic relays connected by conductors to a current source located with in the handle.

The essence of the claimed baton is illustrated by examples of implementation and graphic images. In FIG. 1 is a schematic sectional view of an embodiment of a baton using a coil spring as a means of forcing a weight to move toward the handle.

Example 1

The baton contains a hollow body 1, one of the ends of which serves as a handle 2. A movable weight 3 is placed in the hollow body, which is connected by means of a rod 4 to a means of forcing it to the handle, made in the form of a coil spring 5 located in the handle. The baton is equipped with a means that starts moving the weight to the handle 6, made in the form of a lever, releasing a spiral spring stretched in the handle. Attached to the weight is a tool for returning it to its initial state 7, made in the form of a spiral spring or rubber cord, the second of which is connected to the end of the working end of the baton.

The baton is used as follows.

In its initial position, the spring 5 (Fig. 1) is stretched and fixed with the lever 6. After swinging with a baton, in the process of dispersal, the user presses the lever 6, the spring 5 is compressed, the weight 3 with the rod 4 is moved to the handle of the baton, the moment of inertia of the baton decreases, and the speed increases. Thus, the energy of the spring passes into the kinetic energy of the baton. After the impact, the spring is again stretched by the user and is fixed using the lever 6, and the weight 3 is returned to its original position by spring (or weight) 7 and the baton is ready for the next impact.

Example 2

The baton contains a hollow body 1, one of the ends of which acts as a handle 2. A movable weight 3 is placed in the hollow body, which is connected via a rod 4 to a means of forcing it to a handle made in the form of a core 8 of an electromagnetic relay 9. The baton is equipped with triggering the movement of the weight to the handle 2, made in the form of a switch 10 installed between the electromagnetic relay 9 and the current source 11 in the handle 2. A means of its return to the initial state 7 is connected to the weight; in the form of a spiral spring or rubber cord, the second of which is connected to the end face of the working end of the baton

The baton is used as follows.

After a swing, in the process of accelerating the baton, the user presses the button (switch) 10, the voltage is supplied from the current source 11 to the electromagnetic relay 9, the core of which is retracted towards the handle. The weight 3 with the help of the rod 4 is shifted to the handle, which leads to a decrease in the moment of inertia of the baton and, accordingly, to an increase in its speed, i.e. the electrical energy of the current source (battery or accumulator) is converted into the kinetic energy of the baton. After the blow, the user stops pressing the switch 10, the relay 9 is de-energized, the core 8 with the help of a spring (or cord) 7 returns to its original position and the baton is ready for the next blow.

Example 3

The baton contains a hollow body 1, one of the ends of which serves as a handle 2. A solenoid 12 is placed in the hollow body, the core 13 of which serves as a movable weight. The baton is equipped with a means that starts moving the weight to the handle 2 made in the form of a switch 10 mounted between the solenoid 12 and the current source 11 in the handle 2.

The baton is used as follows.

After a swing, in the process of accelerating the baton, the user presses the button (switch) 10, the voltage is supplied from the current source 11 to the solenoid 12, the core 13 of which is retracted towards the handle, which leads to a decrease in the moment of inertia of the baton and, accordingly, to increase its speed, t. e. the electrical energy of the current source (battery or accumulator) is converted into the kinetic energy of the baton. After the blow, the user stops pressing the switch 10, the solenoid 12 is de-energized, the core 13 with the help of a spring (or cord) 7 returns to its original position and the baton is ready for the next blow.
