DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are provided by way of example so that those skilled in the art can fully understand the spirit of the present invention. Therefore, the present invention is not limited to the embodiments described below, but may be embodied in other forms. In the drawings, the width, length, thickness, etc. of components may be exaggerated for convenience. Like reference numerals designate like elements throughout the specification.

1 is a schematic view of a running leisure sports system.

As shown in FIG. 1, a running leisure sports system includes a cable 30 that is interposed between upper and lower cable support structures 10, 20 and upper and lower cable support structures 10, 20. The top cable support structure 10 may include a deck having a platform configured to facilitate the user to ride on and off.

The upper cable support structure 10 and the lower cable support structure 20 may be provided with communication means for confirming that the user is safely lowered. Wireless communication means is provided when the distance between the upper cable support structure 10 and the lower cable support structure 20 is several kilometers.

Since the cable 30 is made of a metal material, the tension may change in a seasonal change. Therefore, it is necessary to adjust the length of the cable 30 by measuring the tension periodically. For example, the length of the cable 30 should be reduced in summer, and the length of cable 30 should be increased in winter.

A cable trolley 100 is attached to the cable 30 along the cable 30 and a harness 1 for the user is suspended from the trolley 100.

The cable 30 near the lower cable support structure 20 is provided with a terminal brake 200 for reducing the speed of the trolley 100 sliding along the cable 30.

2 is a schematic view of the terminal brake shown in Fig.

1 and 2, the terminal brake 200 is disposed along the cable 30 with a cable 30 and a common axis. The terminal brake 200 is disposed near the lower cable support structure 20. The terminal brake 200 includes a plurality of units consisting of a coil spring 210 and a spacer 220 coupled to each other.

The coil spring 210 and the spacer 220 are appropriately selected so that the speed of the trolley 100 can be gradually reduced. If the elasticity of the coil spring 210 is too strong and the spacer 220 is too light, an impact may be applied to the user. Conversely, if the elasticity of the coil spring 210 is too weak and the spacer 220 is too heavy, there is a danger that the trolley 100 is not sufficiently decelerated.

3 is a side view of the spacer shown in Fig. 3, the spacer 220 includes a body portion 221 and a support portion 226. As shown in Fig. The body portion 221 has a first surface 222 and a second surface 223 side by side with the first surface 222. The body portion 221 may be made of a metal such as stainless steel. A bore 224 through which the cable 30 passes is formed in the center of the body 221. The body portion 221 is divided into two pieces so as to be easily attached to the cable 30. [ The body portion 221 can be assembled through a screw connection.

The support portion 226 is coupled to the body portion 221 so as to protrude from the first surface 222 and the second surface 223 of the body portion 221, respectively. The support portion 226 is also formed with a bore 227 through which the cable 30 passes, and is divided into two pieces so as to be easily coupled to the cable 30. The support portion 226 is formed by wrapping the engagement protrusions 225 extending from the first surface 222 and the second surface 223 of the body portion 221 with the support portions 226 separated into two pieces, 226 can be coupled to the body portion 221 in a screwed manner.

Figure 4 is a side view of the spring shown in Figure 2; 4, the coil spring 210 includes a body portion 211, an extension portion 212, and a hook portion 213. As shown in Fig. The body portion 211 provides an elastic force as a spirally wound portion. At both ends of the body portion 211, a support portion 226 of the spacer 220 is fitted. The extension portion 212 extends radially outward at both ends of the body portion 211. A hook portion 213 bent to engage with the body portion 221 of the spacer 220 is connected to an end of the extension portion 212.

A method in which the support portion 226 of the spacer 220 is inserted into the body portion 211 of the coil spring 210 and the hook portion 213 of the coil spring 210 is hooked on the body portion 221 of the spacer 220 The spacer 220 and the coil spring 210 can be coupled to each other. The unit units including one spacer 220 and one coil spring 210 are connected to each other to form the terminal brake 200.

2, the unit units are divided into at least two groups according to the distance from the trolley 100, and as the group farther from the trolley 100, the modulus of elasticity of the coil spring 210 of the unit units belonging to the group . In FIG. 2, the elastic modulus Ka of the coil springs 210 of the unit units belonging to the group A is the smallest, and the elastic modulus Kc of the coil springs 210 of the unit units belonging to the C group is the largest. The trolley 100 approaching at a high speed can be smoothly buffered by using the coil spring 210 having a small modulus of elasticity in the A group. After the coil springs 210 of the group A are decelerated to some extent, since the coil spring 210 having a large elastic modulus of the B group and the C group is buffered, the coil spring of the B group and the C group A great impact is not applied to the passenger even in the step of buffering by the passenger 210.

In addition, it is preferable to make the weight of the spacer 220 lighter in the order of the A group, the B group, and the C group in order to provide a soft buffer.

2, a restraint member 230 is provided on the side of the upper cable support structure 10 of the terminal brake 200 so as to be movable along the cable 30. As shown in Fig. The restraint member 230 engages with the spacer 220 of the unit unit at the side end of the upper cable support structure 10. The restraint member 230 serves as an interface for transmitting the momentum of the sliding trolley 100 to the terminal brake 200. The terminal brake 200 absorbs and disperses the momentum transmitted through the restraint member 230, thereby causing the trolley 100 to gradually stop.

The restricting member 230 includes a sliding portion 231 that moves along the cable 30 and a circular cap 232 that is rotatably installed on the sliding portion 231 and is configured to be coupled to the trolley 100 do.

5 is a perspective view of an embodiment of a trolley for leisure sports and a restraining member according to the present invention. 5, the trolley 100 includes a frame 110, a brake assembly 120, a guide 130, a pulley mount 140, and a carriage 150 which form the body of the trolley 100 do.

The frame 110 forms the body of the trolley 100 to which other components are coupled. The frame 110 may be made of a suitable material, for example, aluminum. The frame 110 has a first end 111 and a second end 112. The first end 111 is a rear end with respect to the sliding direction, and the second end 112 is a front end. The frame 110 is elongated along the cable 30. The frame 110 is located under the cable 30. [

The brake assembly 120 is installed near the first end 111 of the frame 110. A guide 130 is installed on the second end 112 of the frame 110.

The guide 130 has two extensions 131 that extend away from one another. A capture 232 of the restricting member 230 is fitted to a vertex portion where the two extensions 131 of the guide 130 meet. When the trolley 100 descends and reaches near the position where the terminal brake 200 is installed, the guide 130 transmits the amount of movement of the trolley 100 to the restraint member 230 while engaging with the capture 232. The momentum transmitted to the restricting member 230 is dispersed and absorbed by the coil springs 210 of the terminal brake 200.

The pulley mount 140 is mounted to the frame 110 at a position between the brake assembly 120 and the second end 112. The pulley mount 140 extends in the direction of the cable 30 from the frame 110. The pulley mount (140) supports at least one pulley (141) that rolls along the cable (30). The pulley 141 is rotatably installed near the end of the pulley mount 140 extending in the direction of the cable 30. [ Since the frame 110 hangs under the cable 30, the pulley 141 contacts the upper surface of the cable 30. [

A slit 113 is formed between the pulley mount 140 and the second end 112 to which the carriage 150 to which the harness 1 is mounted is engaged. Thus, the weight of the user is applied in a section between the pulley mount 140 and the second end 112.

The position of the brake assembly 120 and the user is suspended in the opposite direction with respect to the pulley mount 140 so that the weight of the user generates a torque such that the brake assembly 120 presses the lower surface of the cable 30. [ The larger the torque is, the greater the frictional force by the brake assembly 120 is. Accordingly, the frictional force is changed depending on the position of the carriage 150. [ As the carriage 150 approaches the guide 130, the frictional force increases, and as it approaches the pulley mount 140, the frictional force decreases.

The position of the carriage 150 can be appropriately adjusted by the inclination angle of the cable 30, the weight of the user, the desired running speed, and the like. If the frictional force is too great, the trolley 100 may stop during the running, and if the frictional force is too small, the running speed is too fast and can be dangerous.

6 is an exploded perspective view of the brake assembly shown in Fig.

According to FIGS. 5 and 6, the brake assembly 120 includes a brake pad 121 that is detachable so as to be replaceable when worn. The brake pads 121 are inserted into the left and right brake pad housings 122. The brake pad 121 includes engagement projections 123 protruding from both sides and the brake pad housing 122 has grooves 124 of a shape and size capable of receiving the engaging projections 123. [ The brake pad 121 may be made of a thermosetting resin.

Although the brake pads 121 are shown as one piece in FIG. 6, the brake pads 121 may be formed of a plurality of pieces having different materials or shapes from each other to control brake performance. Also, the spacing between each piece can be adjusted.

When assembled, the brake pad housing 122 fixes the brake pads 121 on three sides. The brake pad housing 122 includes a groove 125 of a size and shape capable of receiving the frame 110 formed below. Brake pad housing 122 is secured to frame 110 by various fasteners.

The brake assembly 120 includes a pair of side plates 126 for reinforcing the brake pad housing 122.

In addition, the brake assembly 120 includes a pair of idle wheels 127. The idle wheels 127 are disposed above and below the brake pad 121 with the cable 30 therebetween. The idle wheels 127 are mounted on a bracket 129 coupled to the side plate 126. Each of the idle wheels 127 is located near both ends of the brake pad 121 in the longitudinal direction.

The idle wheel 127 cooperates with the brake pad 121 to adjust the friction force between the brake pad 121 and the cable 30. This makes it possible to efficiently control the running speed of the trolley 100 and to extend the service life of the brake pad 121. That is, the idle wheel 127 relieves the pressure applied to the right end of the brake pad 121 in which the greatest pressure is applied, and applies the pressure evenly to the brake pad 121 as a whole.

The idle wheel 127 also serves to secure the trolley 100 to the cable 30 in a crisis situation in which the pulley mount 140 is damaged and the trolley 100 can not be supported.

Figure 7 is a schematic diagram of a trolley recovery system. 7, the recovery system includes a recovery line 40, a power transmitting member 50, a connecting line 60, a control device 70, a traveling speed measuring means 80 and a sensor 90. [

The withdrawal line 40 extends near the bottom cable support structure 20 in the vicinity of the top cable support structure 10. The collection line 40 forms a closed loop. In addition, the recovery system includes a plurality of pulleys 41 that support the recovery line 40 and are provided for switching directions. The pulleys (41) allow the collection line (40) to run in parallel with the cable (30). The sweep line 40 is provided with a swivel 42 for preventing the sweep line 40 from twisting.

When the trolley 100 slides along the cable 30, the trolley 100 and the collection line 40 are separated from each other, and the collection line 40 does not travel. When the trolley 100 is withdrawn along the cable 30, the trolley 100 and the recovery line 40 are connected to each other via the connection line 60, and the recovery line 40 runs.

One end of the connecting line 60 is attached to the trolley 100 and the other end of the connecting line 60 can be quickly connected to the return line 40 at a one-touch speed. .

When the recovery line 40 runs in a clockwise direction so that the trolley 100 can return to the boarding position near the upper cable support structure 10 along the recovery line 40, Is connected to the left side portion of the engine 40, and is connected to the right side portion when traveling in the counterclockwise direction.

Since the swivel 42 described above is thicker than the recovery line 40, it prevents the recovery line 40 from being twisted and supports the hook of the connection line 60 so that the connection line 60 is positioned at the position where the recovery line 40 is coupled Can play a role.

The power transmitting member 50 serves to run the collecting line 40 clockwise and counterclockwise. The power transmitting member 50 may include an inverter and a motor and a drive pulley wound around the recovery line 40. [ Further, it may further include a switch that can change the direction of rotation of the motor.

The control device 70 includes a processor and controls the power transmitting member 50 by receiving signals from the traveling speed measuring means 80 and the sensor 90. The signals from the traveling speed measuring means 80 and the sensor 90 are transmitted to the control device 70 provided in the lower cable supporting structure 20 through the radio transmitting device 11 provided in the upper cable supporting structure 10 .

The sensor 90 is connected to the processor of the control device 70 so that the trolley 100 senses its proximity to the upper cable support structure 10 and transmits a stop signal to the control device 70. [ The control device 70 transmits a stop command to the power transmitting member 50 to cause the power transmitting member 50 to stop the running of the collecting line 40 in response to the stop signal. Further, the control device 70 transmits a command to cause the power transmitting member 50 to rotate the collecting line 40 in the opposite direction when the collecting line 40 is driven again. The control device 70 may further include a switch for inputting a re-run command of the return line 40. [

The running speed measuring means 80 serves to generate an electric signal capable of measuring the running speed of the collecting line 40. The control device 70 receives the electric signal of the traveling speed measuring means 80 and calculates the traveling speed of the collecting line 40 and compares the traveling speed with a predetermined speed. If the speed is equal to or higher than the predetermined speed, To the stop command power transmitting member 50 for stopping the running of the vehicle. The traveling speed measuring means 80 measures the traveling speed of the collecting line 40 when the trolley 100 approaches a distance of about 10 to 20 m from the upper cable supporting structure 10, Thereby stopping the running of the line 40. When the collection line 40 stops running, the trolley 100, which was collected along the cable 30, also stops. Therefore, the trolley 100 can reach the user boarding position near the upper cable support structure 10 at high speed, thereby preventing the user or the operator from being placed in a dangerous situation.

The traveling speed measuring means 80 includes a magnetic field generating means 81 provided on the collecting line 40 and a sensor 82 provided around the traveling path of the collecting line 40. The magnetic field generating means 81 may be a permanent magnet. More specifically, the magnetic field generating means 81 may be a rubber magnet of a certain length disposed inside the recovery line 40. The magnetic field generating means 81 is connected to the recovery line 40 to which the trolley 100 is connected so that the traveling speed when the trolley 100 approaches a distance of about 10 to 20 m from the upper cable support structure 10 ) At a point 10 to 20 m ahead of the point of view.

The sensor 82 generates an electric signal when the magnetic field generating means 81 passes, and transmits the electric signal to the control device 70. The sensor 82 may be mounted on a pulley 41 installed to switch the direction of the recovery line 40. The sensor 82 may be installed in each of the pair of pulleys 41 or may be installed in one of the pulleys 41. [

When the pair of sensors 82 is used, the traveling speed of the collection line 40 can be calculated using the difference in the generation time of the electric signals measured by the pair of sensors 82, The traveling speed can be calculated by using the generation time of the electric signal and the length of the magnetic field generating means 81. [

The control device 70 also includes a first section in which the trolley 100 begins to move away from the lower cable support structure 20 along a path that is withdrawn along the cable 30, 10 and a second section between the first section and the third section to control the traveling speed of the collecting line 40. [ The control device 70 receives the rotation number of the motor of the power transmitting member 50 and calculates the distance traveled by the trolley 100 along the cable 30 and accordingly controls the rotation speed of the motor. For example, in the first section, the motor is rotated at a slow speed. In the second section, the motor is rotated at a very high speed to reduce the cycle time. In the third section, the motor is rotated at a very low speed to secure the safety of the occupant and the operator . The traveling speed measuring means 80 described above preferably measures the speed in the third section.

The permanent magnet 160 is installed at the first end 111 of the trolley 100 so as to fix the recovered trolley 100 to the boarding position. A cable 30 is provided with an electromagnet 95 configured to engage with the permanent magnet 160 so that the trolley 100 recovered along the cable 30 does not slip again along the cable 30 by gravity. The polarity of the electromagnet 95 is switched by the control device 70. [ When the occupant is ready to glide on the harness 1 connected to the trolley 100, the operator operates the switch connected to the controller 70 so that the trolley 100 is separated from the electromagnet 95.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
