BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing a wire regulating device of the present invention. Fig.

The wire adjustment apparatus shown in FIG. 1 may include a guide unit 200 and a torsion prevention module 100.

The guide portion 200 may extend parallel to the winch 10.

The winch 10 may be an element that lifts or drops a weight by winding the wire 30 on a cylindrical drum extending along the first direction.

It is preferable that the length of the wire 30 that is unwound from the winch 10 or wound on the winch 10 according to the rotation angle of the winch 10 is constant. To this end, the wire 30 may be wound on the winch 10 in the form of a coil.

According to this configuration, when the position where the wire 30 is unwound from the winch 10 is referred to as the first position P1, the first position P1 is the direction in which the winch 10 extends (the winch 10 ) In the longitudinal direction).

For example, it is assumed that the wire 30 is wound when the winch 10 rotates in the normal direction and the wire 30 is disengaged when the winch 10 is rotated in the reverse direction as shown in FIG.

When the wire 30 is wound, the first position P1 gradually changes to the left, and when the wire 30 is released, the first position 1 gradually changes to the right.

The operation in which the wire 30 is wound or unrolled to the winch 10 while the first position P1 is gradually moved is to move the wire 30 to the end portion of the wire 30 by moving the wire 30 in a direction away from the winch 10, Can be done normally when connected. In other words, the wire 30 can be normally wound or unwound to the winch 10 only if there is a tension that holds the wire 30 tight.

However, if an object connected to the wire 30 moves in a direction approaching the winch 10 regardless of the rotation of the winch 10, the wire 30 can not maintain the tension in the tight state.

For example, a winch 10 installed in a ski jump simulator is assumed.

2 is a schematic view showing a ski jump simulator.

The ski jump simulator may be a device that provides an environment similar to an actual ski jump within a limited space.

The ski jump simulator may be provided with a harness 50 worn by the user. The harness 50 can be connected to the winch 10 via the wire 30. Then, the winch 10 can be moved along the rails provided on the ceiling.

When the user makes a jump at the foot plate 70, the winch 10 winds the wire 30 to float the user in the air. By the way, when the user senses the jump and the winch 10 rotates, the wire 30 is lifted up. The wire 30 thus received can be twisted in the winch 10.

3 is a schematic view showing a state in which the wire 30 is twisted.

When the wire 30 extends in the second direction ②, for example, along the gravity direction, the wire 30 is lifted up when the external force F independent of the winch 10 is applied in the opposite direction of the second direction ②. The wire 30 thus lifted can be bent in the middle or over a portion already wound on the winch 10. According to this, normal operation of the winch 10 is difficult and a safety accident may occur.

Even if an external force F opposite to the extension direction of the wire 30 is applied to prevent this, at least the wire 30 in the winch 10 swings along the first direction 1 or sounds in the opposite direction of the second direction 2 It is necessary to prevent it. For this, the guide part 200 and the anti-twist module 100 can be used.

Referring again to FIG. 1, the guide portion 200 may extend parallel to the winch 10, in which the wire 30 is wound and extends along the first direction 1. The guide portion 200 may be installed at a position P2 spaced apart from the winch 10 in the second direction &thetas;, in which the wire 30 extends.

The anti-twist module 100 can move along the guide portion 200. The through-hole 199 through which the wire 30 unwound from the winch 10 passes may be provided in the anti-twist module 100.

The diameter of the through hole 199 may be less than 1.5 times the diameter of the wire 30. According to this configuration, even if the wire 30 is shaken to the right or to the left due to the external force F, lateral flow is suppressed by the inner wall surface forming the through hole 199 at the second position P2 corresponding to the position of the anti- .

Therefore, according to the anti-twist module 100, in the first section between the first position P1 and the second position P2 in spite of the external force F, the wire 30 is moved in the direction perpendicular to the second direction, It is possible to prevent the phenomenon of flowing along the flow path.

It is preferable that the wire 30 of the first section is not inclined in the second direction. To this end, the wire regulating device of the present invention may include a link portion 300.

The link unit 300 is linked to the winch 10 and the guide unit 200 and is capable of transmitting the movement of the winch 10 to the guide unit 200. The anti-twist module 100 can be automatically moved along the guide unit 200 by the guide unit 200 operated by the link unit 300. Movement of the anti-kinking module 100 is caused by the link portion 300 so that the first position P1 where the wire 30 is unwound from the winch 10 to the first direction 1 and the first position P1 where the anti- ) Can be adjusted in the same manner.

The guide unit 200 may include a first guide 210 and a second guide 220 extending in a first direction.

The first guide 210 can be rotated together with the winch 10 by the link portion 300. By the rotation of the first guide 210, the anti-twist module 100 can move along the first direction 1 '. For example, the first guide 210 and the anti-kink module 100 may have a ball screw configuration. In this case, the first guide 210 can form a screw of the ball screw, and the anti-twist module 100, which forms the ball of the ball screw, moves along the rotation of the first guide 210, It is possible to perform linear motion along the extension direction.

The second guide 220 may be used to prevent the anti-tangle module 100 from being rotated by the rotation of the first guide 210. The second guide 220 is provided parallel to the first guide 210 and the anti-twist module 100 supported by two elements, the first guide 210 and the second guide 220, . Accordingly, the second guide 220 can maintain the posture of the anti-twist module 100 constant and can prevent the through hole 199 extending along the second direction 2 from tilting.

The link 300 may include a first gear 310 connected to the rotation axis of the winch 10 and a second gear 320 connected to the rotation axis of the guide unit 200.

As the winch 10 rotates, the wire 30 can be wound or unwound on the wire 30 along the first direction 1 (positive or negative direction). At this time, if the gear ratio of the first gear 310 and the second gear 320 is properly adjusted and the two are connected, the wire 30 is pulled from the winch 10 in the first direction by the rotation of the winch 10 The first position P1 of the loosening and the second position P2 of the anti-twist module 100 can be matched.

The first position P1 varying in the first direction by the rotation of the winch 10 may vary depending on the thickness of the wire 30. [ For example, if the wire 30 is rotated when the winch 10 is rotated at the same speed, the first position P1 can move along the first direction 1 at a high speed. If the thickness of the wire 30 is reduced, the first position P1 will move along the positive or negative direction of the first direction 1 at a slow speed.

In order to adaptively cope with the moving speed of the first position P1 that varies depending on the thickness of the wire 30 installed on the winch 10, the transmission 330 (the first gear 310) and the second gear 320 May be provided.

The transmission 330 is an element that connects the first gear 310 and the second gear 320. The transmission 330 is connected to the wire 310 so that the second position P2 of the anti- The rotation speed of the second gear 320 can be adjusted to the rotation speed of the first gear 310 according to the thickness of the second gear 30.

For example, the transmission 330 may be installed between the first gear 310 and the second gear 320. Accordingly, the transmission 330 can be configured with one or more gears having an appropriate gear ratio to adjust the rotational speed ratio or the rotational angle ratio of the first gear 310 and the second gear 320.

4 is a perspective view showing the wire adjusting apparatus of the present invention.

The wire 30 is wound in a coil shape on the winch 10 extending along the x-axis corresponding to the first direction.

The anti-tangle module 100 is disposed at a position spaced apart from the winch 10 along the z-axis to support the wire 30 extending in the negative direction of the z-axis. The anti-kink module 100 is configured to move along a guide portion 200 that extends along the x-axis and is disposed at a different location from the winch 10 on the z-axis.

A first gear 310 is connected to the winch 10 and a second gear 320 is connected to the guide portion 200. The two gears 320 are connected to each other between the first gear 310 and the second gear 320, A transmission 330 is provided. The transmission 330 may be composed of one or more gears and may be replaced with a gear adaptive to the thickness of the wire 30 when the thickness of the wire 30 is varied.

According to the guide unit 200 and the anti-twist module 100 described above, even when the wire 30 is swung in the direction different from the z axis by the external force F, In the first section, no shaking occurs.

Next, a configuration for preventing the wire 30 of the first section from being heard along the positive direction of the z axis by the external force F will be described.

FIG. 5 is a perspective view showing the anti-twist module 100 of the present invention, and FIG. 6 is an exploded perspective view showing the anti-twist module 100 of the present invention.

When the wire 30 released from the winch 10 extends along the second direction 2, the anti-tangle module 100 may be disposed at a second position P2 spaced from the winch 10 in the second direction.

The torsion preventing module 100 can maintain the tension of the wire 30 constant in the first section between the first position P1 and the second position P2 where the wire 30 is unwound from the winch 10. [ To this end, the anti-tangle module 100 grabs the wire 30 when the winch 10 stops and releases the grip state when the winch 10 is rotated.

The anti-twist module 100 may be provided with a grip part 110 for grabbing the wire 30 and a control part 150 for determining whether the grip part 110 is to be gripped. When the end of the wire 30 is connected to the harness 50 worn by the user, the end of the wire 30 can be heard toward the winch 10 due to the jump of the user. The grip portion 110 can grasp the wire 30 when the wire 30 is lifted toward the winch 10 as described above.

Even if the wire 30 is moved upward by the user jumping, if the winch 10 pulls the wire 30 faster at that point in time, the wire 30 can be prevented from being lifted from the winch 10. However, since it is difficult for the user to know when to jump, the winch 10 is difficult to be driven at the time of the jump. Even if the jump point is grasped, if the winch 10 rotates immediately, the user will feel that the user is dragged to the wire 30 rather than feeling that the user is jumping. Therefore, at least in the ski jump simulator, the winch 10 is preferably rotated after the jump of the user so that a free jump is ensured.

According to this, the wire 30 wound on the winch 10 can be heard. However, according to the anti-twist module 100 of the present invention, when the winch 10 is stopped without rotating, the wire 30 is gripped at the position P2, so that at least the wire 30 is prevented from being lifted from the winch 10 .

The controller 150 may determine the operation mode of the grab 110. More specifically, the control unit 150 moves the grip unit 110 in one of a first mode in which the grip unit 110 grabs the wire 30 and a second mode in which the grip unit 110 releases the grip state .

When the control unit 150 is driven by electric power, the control unit 150 is turned off when the electric power is interrupted. In this case, the pressing portion 130 may be provided.

The pressing portion 130 can press the grip portion 110 in the direction in which the wire 30 is gripped. According to this, it is possible to prevent the wire 30 from being twisted normally.

The control unit 150 can be controlled by a control signal generated from a control unit (not shown) that rotates the winch 10. When the control signal requests release of the grip state, the control unit 150 can overcome the force of the pressing unit 130 and release the grip state of the grip unit 110.

The torsion prevention module 100 may be provided with a body portion 190 having a through hole 199 through which the wire 30 penetrates. At this time, the grip portion 110, the pressing portion 130, May be installed in the body portion 190.

In order to prevent the wire 30 from rubbing against the through hole 199 of the body portion 190, restraining portions 170 and 170 'may be provided at both ends of the body portion 190 in the second direction & have.

The restricting portion 170 can prevent the wire 30 from flowing in a direction different from the second direction (2). Also, the restricting portion 170 can prevent the wire 30 from being damaged due to friction.

For example, the restraining portion 170 may include a first restraining means 171 and a second restraining means 172 which extend in a direction perpendicular to the second direction. At this time, it is preferable that the first restraining means 171 and the second restraining means 172 are perpendicular to each other.

For example, when the second direction is z-axis, the first restraining means 171 may include two rollers that rotate about a rotational axis extending along the y-axis direction. And the wire 30 can pass between the two rollers. To this end, the distance between the two rollers is preferably equal to or greater than the diameter of the wire 30. The wire 30 passing through the first constraining means 171 can be restricted from flowing in the x-axis direction.

The second constraining means 172 may include two rollers that rotate about a rotation axis extending along the x-axis direction. The wire 30 passing between the two rollers can be restricted in the flow in the y-axis direction.

According to the first restraining means 171 and the second restraining means 172 described above, the x-axis flow and the y-axis flow of the wire 30 can be restricted. When the wire 30 moves along the second direction 2, the roller contacted with the wire 30 does not slip and rotates, so that damage to the wire 30 can be prevented.

When the body portion 190 having the grip portion 110, the pressing portion 130 and the adjusting portion 150 is integrally formed, it is difficult to assemble the respective elements.

To improve the productivity of the anti-kink module 100, the body portion 190 may include a body means 191 and a holding means 193.

A plurality of body means 191 may be assembled together to form a through hole 199 through which the wire 30 passes. For example, in FIG. 6, four body means 191 are assembled.

The holding means 193 can surround the outer periphery of the assembly in which the plurality of body means 191 are assembled and maintain the assembled state of the assembly including the plurality of body means 191. [

The through hole (199) through which the wire (30) penetrates may be a plane in which a plurality of arcs are continuous. At this time, each body means 191 can form each arc. Accordingly, when a plurality of body means 191 are assembled, a circular shape in which the respective arcs are combined is formed, and the circular shape at this time can be the through hole 199.

Therefore, when the plurality of body means 191 are assembled, the through hole 199 is also disappeared, but this concern can be eliminated by the holding means 193.

When the body portion 190 is divided into the plurality of body means 191, the grab 110, the pressing portion 130, and the adjusting portion 150 disposed around the through hole 199 can be easily installed have.

For example, the grip portion 110 may include a rotation axis o extending along a direction perpendicular to the second direction (2). At this time, the rotation axis o may be installed in the middle portion of the body portion 190 in the second direction (2). If the body portion 190 is integrally formed, it is obvious that the rotation axis o is difficult to install.

However, according to the present invention in which the body portion 190 is divided into a plurality of body means 191, one side of the rotation axis o is supported by a specific body means 191, and the other side of the rotation axis o is assembled with a specific body means 191 The other body can be supported. According to this, the installation of the grab 110 can be completed by inserting one side of the rotary shaft o to the specific body means 191 and sandwiching the other side of the rotary shaft o to the other body means 191.

The grip portion 110 may include a rotating shaft 118, an elongating means 111, and a grazing means 113.

The extending means 111 can extend in the direction from the rotating shaft 118 o toward the winch 10. The wire 30 may be tilted away from the wire 30 as it approaches the winch 10. The elongating means 111 is inclined to the wire 30 to prevent the elongating means 111 from contacting the wire 30 when the elongating means 111 is rotated about the rotational axis o.

The grappling means 113 can extend in a direction away from the winch 10 on the basis of the rotation axis o. A protrusion 114 protruding toward the wire 30 may be provided at an end of the grappling means 113. At this time, the projection 114 may be an element directly grasping the wire 30.

The pressing portion 130 may include a compression spring whose one end is supported by the body means 191 and the other end is supported by the grappling means 113. At this time, the number of the compression springs may be the same as the number of the grip portions 110.

The adjuster 150 may include an electromagnet mounted on a face of the body means 191 that faces the elongating means 111. [

It may be difficult to assemble when the pressing unit 130 and the adjusting unit 150 are installed together on one body unit 191. Accordingly, the body portions 190 and 190 'can be separated into a plurality of assemblies along the second direction.

In the figure, an adjusting unit 150 is provided on an upper body part 190 and a pressing part 130 is provided on a lower body part 190 '. A through hole 199 'continuous with the through hole 199 formed in the upper body portion 190 may be formed on the lower body portion 190'. Since the lower body portion 190 'is also divided into a plurality of body means, a holding means 193' for supporting the body means assembled with each other may be provided.

Figures 7 and 8 are schematic diagrams illustrating the first operation of the anti-kink module 100 of the present invention. Here, the first operation may mean an operation mode in which the grip portion 110 grabs the wire 30. [

The protection portion 119 may be added to prevent the rotation shaft provided on the rotary shaft 118 or the body means 191 from being damaged.

The protective portion 119 may be interposed between the body means 191 and the rotary shaft 118. The protection portion 119 may be formed with a hole or a groove into which the one end of the rotation shaft 118 is inserted.

The protector 119 may have a larger volume than the rotary shaft 118. The protector 119 may be provided with a plurality of holes or grooves provided with different rotational shafts.

For example, in FIG. 7, four grab portions 110 are provided, so that the rotational axis o is also four. In this case, since each of both ends of the rotary shaft is supported, a total of eight supporting points are required. The protective portion 119 may be disposed between the respective grip portions 110, and a total of four may be provided. In addition, two grooves may be formed in one protective portion 119 to connect different rotational axes o. According to this, the four guard portions 119 can be provided with four grip portions 110. According to this, another assembly including four protective portions 119 and four grab portions 110 is formed. By fitting the assembly at this time to the body means 191, the grab portion 110 can be completed.

The pressing portion 130 can push the grab means 113 toward the wire 30. [ According to this, the wire 30 can be grabbed in a state where no power is supplied to the controller 150 as shown in FIG.

When the grip means 113 is positioned below the rotary shaft 118 and presses the wire 30 by the compression spring, if the wire 30 is pulled down by a strong external force, the grip state can be partially released. On the other hand, if the wire 30 is lifted up by the external force F or if the winch 10 rotates, the protrusion 114 provided at the end of the grappling means 113 becomes more tightly caught in the wire 30.

Therefore, according to the embodiment in which the grappling means 113 is located below the rotation axis, the phenomenon in which the wire 30 is heard can be reliably prevented, and at the same time, an accident that the user is injured by the abnormal operation of the winch 10 .

Even if the wire 30 is loosened due to a malfunction of the winch 10 in the ski jump simulator, the protrusion 114 hits the wire 30 by the elastic force of the compression spring, so that the wire 30 is loosely released and there is no problem . However, when the user comes up with a malfunctioning winch 10, a safety accident such as being struck on the ceiling or caught in the winch 10 is expected. However, according to the grip portion of the present invention, pulling down the wire in a state where the wire is gripped can be allowed to some extent, but pulling up is never allowed. As a result, it is preferable that the grab device 113 is positioned below the rotary shaft.

Figures 9 and 10 are schematic diagrams illustrating a second operation of the anti-kink module 100 of the present invention. Here, the second operation may mean an operation mode in which the grip portion 110 releases the grip state of the wire 30. [

When the grip state of the wire 30 needs to be released, the control unit can control the control unit 150 to operate.

The magnet 112 influenced by the magnetic force of the electromagnet may be installed on the surface of the extending portion 111 facing the regulating portion 150 when the regulating portion 150 is provided with the electromagnet. At this time, it is preferable that the magnet 112 is disposed such that the N pole or the S pole faces the control unit 150.

If the regulating unit 150 includes a magnetic body attached to the magnet 112 or has an electromagnet operated in a polarity opposite to that of the magnet 112, Can be supplemented.

In addition, when the control unit 150 operates in the same polarity as the magnet 112 in the second operation, the repelling means 111 moves in a direction away from the control unit 150 by the repulsive force, and the rotation axis is rotated. Then, by the rotation of the rotary shaft, the grab device 113 is moved away from the wire 30, and the grip state of the wire 30 is released.

FIG. 11 is a schematic diagram showing an adjustment unit 150 installed in the anti-twist module 100 of the present invention.

When the control unit 150 is operated by an external power or an external control signal such as an electromagnet, the control unit 150 may be connected to a power line or a signal line. At this time, the adjusting unit 150 may be installed on the outer surface of the body 190 to be connected to an external power line or signal line.

For this, a groove or the like for accommodating the adjusting part 150 may be formed on the outer surface of the body means 191. The groove may be provided at a position facing the holding means 193. According to this, the fixing of the assembling part can be completed by installing the holding part 193 after the assembling part is provided in the groove. This can simplify the manufacturing process.

The wire adjusting apparatus of the present invention can be adapted to an environment in which the wire 30 can be lifted up regardless of the driving of the winch 10, such as a ski jump simulator. However, it is reminded that it can be applied to an environment where the wire is always pulled down, such as an elevator or a crane, in order to prevent a safety accident as much as possible.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims.
