Moving Restraint {APPARATUS HAVING MOVING RESTRICT DEVICE}

The present invention relates to a movement restraint device having a bobbin function.

In a system in which a projectile is loaded inside a tube and fired, in order to safely transport the loaded tube, the tube must be transported in a state in which the projectile is constrained using a device that restricts the movement of the projectile.

Among the existing methods of restraining the movement of the projectile, the movement restraint device for attaching a bullet support or the like to the projectile has a simple structure and easy design. However, there is a disadvantage in that the driving performance is reduced when the projectile is launched by causing air resistance, the projectile should be released from the tube and at the same time the separation of the movement restraint must be made.

In addition, the movement restraint apparatus directly attached to the tube has a disadvantage in that the structure of the movement restraint apparatus becomes complicated and large in order to design such that interference with the projectile does not occur during launch. In particular, when the artifacts of the movement restraint are generated together with the launch of the projectile, it may affect other installations around.

In the state where the space for mounting on the tube is determined, as the size of the projectile increases, a space limitation for designing the movement restraint device occurs.

Therefore, the development of a movement restraint device that minimizes the space occupied by the device and does not cause interference with the projectile during launch may be considered.

The present invention is to provide a movement restraint device that can be structurally downsized without interference occurs during the launch of the projectile.

In order to achieve the above object of the present invention, the movement restraint apparatus according to an embodiment of the present invention has a hollow portion formed to receive a projectile, and at least one hole passing through one side to communicate with the hollow portion. And a constraining portion that restrains movement of the projectile and is installed outside of the tube so that interference does not occur in the interior of the tube when the projectile is launched. A cord that penetrates the hole to constrain the movement of the projectile and wraps at least a portion of the projectile, and a cord configured to receive the cord and provides an elastic force to wind and recover the cord drawn out to constrain the projectile A winding portion, connected to the string drawn out from the string winding portion, to fix the string, and to the projectile To recover the bound off when the request line to the spiral part and julgam and the connection with the line comprising releasably including government.

According to an example related to the present invention, the bobbin winding unit, a reel (elastic force) acts on the rotating shaft to automatically wind the string, and the string to prevent the string released from the reel to be wound into the reel It may include a bobbin fixing for fixing the.

The bobbin fixing part may include a bobbin switching part for operating the bobbin fixing part to receive or receive a signal from a controller for controlling the restraint of the projectile to restrain or allow the movement of the bobbin.

The bobbin winding unit may include a bobbin sensing unit connected to the reel and detecting whether the reel has completed the recovery of the string when the projectile release request is released.

According to another embodiment related to the present invention, the fixing unit is connected to the line surrounding the projectile, the line fixing unit for fixing the line, and receives a signal from the control unit for controlling the restraint of the projectile to the fixing unit It may include a signal receiving unit for operating the string fixing portion to release the connection of the fixed string.

The string fixing part may be disconnected from the string as the string fixed to the string fixing part is cut.

According to another example related to the present invention, the bobbin portion and the fixing portion may be integrally formed so that the restraint part is connected to the control part by one signal line so that the restraint part can be controlled.

The movement restraint device of the present invention is installed on the outside of the tube in which the projectile is accommodated, and the string restraining the movement of the projectile completely exits from the inside of the tube when the projectile is restrained, so that the projectile does not interfere with the launch path. There is an advantage not to receive.

In addition, since the movement restraint device of the present invention has a simple structure to release the restraint of the projectile, it is possible to miniaturize the device, thereby reducing the space constraints caused by the transport of the tube in which the movement restraint device is installed.

In addition, the detection unit for detecting whether the recovery of the rope restraining the projectile can be provided to contribute to improving the stability of the launch. Therefore, there is a great advantage compared to the existing movement restraint device.

Hereinafter, with reference to the accompanying drawings, the movement restraint device of the present invention will be described in detail. In the present specification, the same or similar reference numerals are given to different embodiments in the same or similar configurations. As used herein, the singular forms "a", "an" and "the" include plural referents unless the context clearly dictates otherwise.

FIG. 1A is a conceptual view illustrating a side of a state where one restrainer is installed in a movement restraint apparatus according to an embodiment of the present invention, and FIG. 1B illustrates a side of a state where two restraints are installed in a movement restraint apparatus illustrated in FIG. 1A. 1C is a conceptual view from above of a state where three restraints are installed in the movement restraint apparatus illustrated in FIG. 1A.

1A to 1C, the movement restraint apparatus 100 according to the exemplary embodiment of the present invention is configured such that the projectile 10 accommodated in the tube 110 is restricted by the constraint portion 120. do. As shown, the restrainer 120 may be installed outside the tube 110 and provided with at least one.

The tube 110 has a hollow portion formed to receive the projectile 10, and has at least one hole 116 penetrating through one side to communicate with the hollow portion. The projectile 10 is charged to the opened side of the tube 110, and at this time, a gap is generated between the inner wall of the tube 110 and the projectile 10. There is a possibility that the projectile 10 may be damaged due to the projectile 10 collides with the inner wall of the tube 110 during the transport of the tube 110 loaded with the projectile 10 due to the separation. Therefore, in the present invention, by using the restraint portion 120, the projectile 10 is firmly fixed to the tube 110 during transportation. Although the cross section of the tube 110 is shown in a circular shape, it may be formed to have a cross section of a polygon other than a rectangle or a rectangle.

The constraining part 120 restrains the movement of the projectile 10, and when the projectile 10 loaded into the tube 110 is ejected to the outside of the tube 110 when the projecting object 10 is fired on the injection path of the projectile 10. In order not to cause interference in the tube 110 is installed outside the projectile 10 can be stably launched to the outside of the tube 110 without being caught.

Hereinafter, the restrictor 120 will be described in more detail with reference to the drawings.

The restraint unit 120 includes a string 130, a bobbin unit 140, and a fixing unit 150.

The string is formed to surround at least a portion of the projectile 10 through the hole 116 to constrain the movement of the projectile 10 loaded inside the tube 110. String 130 may be formed of a fiber or steel wire, it is preferable that the deformation is not large when a tensile force is applied.

The bobbin section 140 is formed to accommodate the string 130 therein, the string 130 is drawn out to the outside and accommodated again inside, to the outside to restrain the movement of the projectile (10) The elastic force is provided to wind and recover the drawn line 130. Specifically, the string 130 accommodated in the bobbin section 140 may be automatically wound into the bobbin section 140 by receiving an elastic force acting inside the bobbin section 140. For example, when an external force is applied to draw the string 130, the string 130 is drawn out of the bobbin winding 140, and when the external force is removed, the bobbin 130 is moved into the bobbin winding 140. It can be automatically recovered into the bobbin section 140 by the acting elastic force.

The fixing unit 150 is connected to the string 130 drawn out from the bobbin winding unit 140 to fix the string 13, and the connection with the string 130 can be released. Specifically, the string 130 drawn out from the bobbin section 140 should be fixed to one side of the bobbin 130 to restrain the projectile 10 and not be recovered by the elastic force acting on the bobbin section 140. In this case, the fixing part 150 is formed to fix one side of the string 130.

On the other hand, when launching the restraint of the projectile 10 should be released, when the request for release of the projectile 10, the string 130 restraining the movement of the projectile 10 can be recovered to the bobbin winding unit 140. As such, the fixing part 150 is configured to be disconnectable from the string 130 connected to fix the string 130. Accordingly, the string 130 is recovered to the bobbin winder 140, and no interference occurs in the path from which the projectile 10 is launched in the tube 110, so that the launch may be stably performed.

As shown in FIG. 1A, one of the restraints 120 may be installed on the outside of the tube 110 to restrain the movement of the projectile 10, and the two restraints 120 may be disposed up and down as shown in FIGS. 1B and 1C. Alternatively, three may be installed to fix the projectile 10 more stably in the tube 110. The number of restraints 120 installed in the tube 110 is not limited, and the number of restraints 120 may be selectively adjusted according to the projectile 10 to be fixed.

In addition, the hole 116 may include first and second holes 112 and 114. In detail, the first hole 112 is formed at one side of the tube 110 so that the string 130 drawn out from the bobbin winding 140 can be passed into the tube 110.

The second hole 114 is formed at one side of the tube 110 so that the string 130 that constrains the movement of the projectile 10 passes through the tube 110 and is connected to the fixing part 150. Accordingly, the string 130 that passes through the tube 110 and the outside is entangled or rubbed with each other during the operation of being drawn out and recovered by the string winding unit 140 and the fixing unit 150. You can prevent it.

On the other hand, the restraint unit 120 is connected to a control unit (not shown) that controls the restraint of the projectile 10 in one signal line so that the operation of the restraint unit 120 can be controlled, as shown in the present invention. 140 and the fixing part 150 may be integrally formed. Accordingly, only one signal line required for the release request of the projectile 10 may be installed in the restraint part 120, thereby simplifying the design of a transmission / reception mechanism for the signal controlling the restraint part 120.

Hereinafter, the bobbin winding 140 will be described in more detail with reference to FIG. 2.

2 is an enlarged conceptual view of the bobbin section 140 in the movement restraint apparatus 100 shown in FIG.

Referring to FIG. 2, the bobbin unit 140 includes a reel 142 and a bobbin fixing unit 144.

The reel 142 is rotated about the axis of the reel 142 and is formed so that the rope 130 can be wound. When an external force is applied to draw the rope 130, the reel 142 is rotated about the axis of rotation and the rope ( As the 130 is released from the reel 142, the drawing is made, and when the external force is removed, the string 130 may be wound around the reel 142 and recovered by the elastic force acting on the rotating shaft. The reel 142 is preferably formed in a cylindrical shape, but may also be formed in a square pillar shape instead of a cylinder.

The bobbin fixing part 144 fixes the string 130 to prevent the string released from the reel 142 from being wound into the reel 142. Accordingly, even when the external force acting to pull out the string 130 is removed, the string 130 may be maintained in the drawn state. For example, the bobbin fixing part 144 may be installed on a path from which the string 130 is drawn, and may fix the string 130 by pressing a part of the string 130. In FIG. 2, the bobbin fixing part 144 is illustrated as being installed inside the bobbin part 140, but may be installed outside the bobbin part 140.

In addition, the bobbin fixing part 144 may include a bobbin switch part 146. The bobbin switch 146 operates the bobbin fixing part 144 to receive or receive a signal from a controller (not shown) that controls the restraint of the projectile 10 to restrain or allow the movement of the string. For example, when the rope 130 is drawn out from the bobbin winding unit 140 when the projectile is restrained, the drawer 130 is not wound and recovered to the bobbin winding unit 140 when the drawing is completed as necessary to restrain the projectile 10. The bobbin switch unit 146 is operated to fix the drawn line 130, and when the release of the projectile 10 is requested, the bobbin switch unit 146 is pulled out by the bobbin fixing unit 144. The string 130 is operated to be recovered to the bobbin winding unit 140 again. The bobbin switch 146 may be formed to partially protrude to the bobbin 140 as shown.

Meanwhile, the bobbin winding unit 140 may include a bobbin sensing unit 148 for sensing whether the string is recovered. The stripe detector 148 may be connected to one side of the reel 142. Upon requesting release of the projectile 10, the string 130 is operated to be recovered into the bobbin section 140 by the bobbin section 140. At this time, the bobbin detecting unit 148 serves to detect whether the reel 142 has completed the recovery of the string 130. Accordingly, after detecting whether the string 130 is recovered first, the projectile 10 may be launched, and the string 130 may not be completely recovered by the bobbin winding 140 so that the restraint of the projectile 10 may be restricted. It is possible to prevent the problem that the projectile 10 can be launched in the unreleased state.

Hereinafter, the fixing unit 150 will be described in more detail with reference to FIG. 3.

3 is an enlarged conceptual view of the fixing part 150 in the movement restraint apparatus 100 illustrated in FIG. 1A.

Referring to FIG. 3, the fixing unit 150 may include a string fixing unit 152 and a signal receiving unit 154.

The string fixing part 150 is connected to the string 130 surrounding the projectile 10 to restrain the movement of the projectile 10 to fix the string 130. For example, the fixing of the string 130 may be made in the form of pressing one side of the string 130 connected to the string fixing part 152. In addition, although the row fixing part 152 is illustrated as being installed inside the fixing part 150, the fixing part 152 may be installed outside the fixing part 150.

The signal receiver 154 receives the signal from the controller that controls the restraint of the projectile 10 and operates the string fixing part 152 to release the connection of the string 130 fixed to the fixing part 150. . Specifically, in order to release the restraint of the projectile 10 during launching, the string 130 should be recovered into the bobbin section 140 by the bobbin section 140.

In this case, when the signal receiver 154 receives a signal for the release request from the controller, the signal receiver 154 may release the connection with the rope 130 connected to the rope fixing part 152. In operation, and as the rope fixing part 152 releases the connection of the rope 130, the rope 130 is recovered by the bobbin winding 140 to release the restraint of the projectile 10. Although the signal receiver 154 is illustrated as being installed inside the fixing unit 150, the signal receiving unit 154 may be installed outside the fixing unit 150.

Meanwhile, the string fixing part 152 may be disconnected from the string 130 as the string 130 fixed to the string fixing part 152 is cut. Specifically, when a part of the rope 130 connected to the rope fixing part 152 and cut by the rope fixing part 152 is cut, an external force for fixing the rope 130 drawn out from the bobbin winding part 140. As a result, the string 130 may be recovered by the elastic force acting on the bobbin section 140, thereby restraining the projectile 10 from being restrained.

Hereinafter, other installation examples of the restrainer 120 for restraining the movement of the projectile 10 will be described with reference to FIGS. 4A to 4C.

4A is a concept illustrating a state in which a line is connected to two restrainers 120 to restrain the movement of the projectile 10 in the movement restraint apparatus 100 illustrated in FIG. 1A, and FIG. 4B is shown in FIG. 1A. 4 is a conceptual diagram illustrating a state in which the strings 130 are connected to each other in the movement restraint device 100 to restrain the movement of the projectile 10, and FIG. 4C illustrates the movement restraint device illustrated in FIG. 4B. In (100) is a conceptual diagram showing a state when the cross section of the tube 110 is a square.

4A and 4B, two or more restraints 120 may be installed outside the tube 110 to restrain the movement of the projectile 10. In this case, the string 130 drawn out from the bobbin section 140 of the restraining unit 120 installed on one side of the tube 110 is a fixed part of the restraining unit 120 installed on the other side of the tube 110. By being connected to and fixed to 150, the movement of the projectile 10 may be restricted. Accordingly, as compared with the case in which the string 130 is drawn out and fixed by one restraint unit 120, the section in which the string 130 surrounds the projectile 10 is reduced, when requesting the release of the projectile 10. An operation of collecting the string 130 by the bobbin winding unit 140 may be performed more quickly, and the possibility of entanglement of the string 130 may be lowered.

Meanwhile, referring to FIG. 4C, when the shape of the tube 110 into which the projectile 10 is charged is a quadrangular shape, the restricting portions 120 are respectively installed on the outer surface of the rectangular tube 110, and FIGS. 4A and 4B. By connecting and fixing the string 130 between the restraints 120 in the manner described above, the movement of the projectile 10 may be restrained in the rectangular tube 110.

In addition, the string 130 is connected to the restraint portion 120 is shown as being connected to one side facing the tube 110, the connection of the string 130 is not facing the tube 110 other It may be connected through one side.

However, the scope of the present invention is not limited to the configuration and method of the embodiments described above, and all or some of the embodiments may be selectively combined so that various modifications may be made to the embodiments. In addition, the present invention can be applied to all equivalents of inventions, such as inventions that can be modified, added, deleted, or replaced at the level of those skilled in the art, It belongs to the scope is self-evident.
