Title: Vehicle stopping apparatus

Description:
TECHNICAL FIELD 
     The present invention relates to a vehicle stopping apparatus including tire infiltration units configured to come into contact with and infiltrate into a tire and a stop plate connected to one side of the tire infiltration units, wherein when the tire is rotated, the stop plate is rotated in conjunction with the rotation of at least one of the tire infiltration units and collides with a vehicle body, thereby completely preventing a vehicle from running away. 
     BACKGROUND ART 
     Generally, for vehicle stopping apparatuses used in sobriety tests, etc., there is widely used a method in which a spike strip provided with a plurality of iron needles is deployed on a road surface so that a tire is punctured when a vehicle passes through a checkpoint while ignoring inspection, thereby preventing the vehicle from running normally. 
     The use of the conventional spike strip has an advantage of making it possible to prevent a vehicle from running away by preventing the normal running of the vehicle. However, steering ability is temporarily lost when a tire is broken, and thus a problem arises in that a secondary accident may be caused when a vehicle is forcibly driven in the state in which the tire has been broken. Furthermore, recently, a vehicle capable of running at a constant speed even when a tire is punctured has been developed. Therefore, another problem arises in that a vehicle cannot be completely prevented from running away by simply puncturing a tire.

     MODE FOR INVENTION 
     Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. In this case, the thicknesses of lines, the sizes of components, etc. shown in the drawings may be exaggerated for the sake of clarity and convenience of description. 
     Furthermore, terms that will be described later are terms that are defined by taking into account their functions in the present invention, and may vary depending on a user, the intention of an operator, or practice. Therefore, the definitions of the terms should be made based on the context of the overall present specification. 
     As shown in  FIG. 1 , a vehicle stopping apparatus  1  according to an embodiment of the present invention includes tire infiltration units  10  configured to come into contact with and infiltrate into a tire and a stop plate  20  connected to one side of the tire infiltration units  10 . Via this configuration, when a tire T is rotated, the stop plate  20  is rotated in conjunction with the rotation of at least one of the tire infiltration units  10  and collides with a vehicle body C, thereby preventing a vehicle from running away. 
     As shown in  FIG. 2 , the plurality of tire infiltration units  10  may be installed on a base  400  in a lengthwise direction, and the stop plate  20  may be connected to the base  400  by connection members  30 , such as connection pins or the like. 
     Via this configuration, when a vehicle that runs away runs over at least one of the tire infiltration units  10  according to the present invention, the tire infiltration unit  10  enters the inside of the tire, as described above. The tire infiltration unit  10  is also rotated by the rotation of the tire, and accordingly the stop plate  20  is also rotated. As the stop plate  20  is rotated, the stop plate  20  is stuck in the vehicle body of a vehicle, and thus the rotation of the stop plate  20  is stopped. Therefore, the forward movement of the vehicle is prevented. 
     The stop plate  20  may use various configurations, and may use, for example, a Hercules wire rope or the like. The purpose of the stop plate  20  is to be caught on a vehicle and prevent the vehicle from moving forward, as described above. As long as the above purpose is achieved, the stop plate  20  falls within the scope of the present invention even when it uses other configurations. 
     As shown in  FIGS. 3 to 7 , each of the tire infiltration units  10  includes a tire contact unit  100  configured to be pressed and lowered by contact with a tire, a case  200  configured to accommodate the tire contact unit  100  therein, and a tire stop unit  300  installed inside the case  200  and configured to be rotated by the tire contact unit  100 . 
     The tire contact unit  100  includes a pointed head part  110  configured to come into contact with and infiltrate into the tire and formed such that an end thereof in the direction of a tire is pointed, a cooperative operation bar  120  disposed below the pointed head part  110  and formed in a bar shape, and a column part  130  disposed below the cooperative operation bar  120 . In other words, as shown in the drawings, the pointed head part  110  is formed to be pointed in the direction of a tire, i.e., a direction toward the tops of the drawings. When a tire runs over the pointed head part  110 , the pointed head part  110  enters the inside of the tire. The cooperative operation bar  120  and the column part  130  are formed below the pointed head part  110 . When a tire runs over the pointed head part  110 , the pointed head part  110 , the cooperative operation bar  120 , and the column part  130  are lowered by a predetermined height. When the column part  130  comes into contact with the bottom surface of the inside of the case  200 , the above lowering is stopped and the pointed head part  110  enters the inside of the tire, as described above. 
     In other words, the cooperative operation bar  120  and the column part  130  are lowered by the lowering of the pointed head part  110 , and the tire stop unit  300  is rotated and projected out of the case  200  in conjunction with the lowering of the cooperative operation bar  120 . The tire stop unit  300  is stuck in a tire, and thus the tire infiltration unit  10  is stuck inside the tire. 
     The case  200  includes a case body  210  formed such that the shape thereof is hollow and the top thereof is open, and a plurality of first openings  220  formed in one side of the case body  210  in a circumferential direction. As described above, the pointed head part  110 , the cooperative operation bar  120 , and the column part  130  are accommodated inside the case body  210 . 
     The tire stop unit  300  includes stop bars  310  rotatably fastened to the side walls of the first openings  220  and bent at a specific angle. In this case, the cooperative operation bar  120  and the column part  130  are lowered by the lowering of the tire contact unit  100 , and the first sides of the stop bars  310  are caught and rotated downward by the lowering of the cooperative operation bar  120  and the remaining sides of the stop bars  310  are projected through the first openings  220  of the case body  230  and enter the inside of a tire. 
     Each of the stop bars  310  includes a stop bar body  311  bent at a specific angle. A through hole  312  is formed in the stop bar body  311 , and a pin P is inserted into the through hole  312 . The pin P is also inserted into a reception hole  221  formed in the side walls of the first opening  220 . Via this configuration, the stop bar  310  is rotatably installed on the side walls. 
     As shown in the drawings, the stop bar body  311  includes a horizontal portion  311 - 1  formed in a horizontal direction, and a vertical portion  311 - 2  bent downward at an end of the horizontal portion  311 - 1  in the direction of the outside of the case  200 . The through hole  312  is formed in a portion where the horizontal portion  311 - 1  and the vertical portion  311 - 2  are connected to each other. A portion of the horizontal portion  311 - 1  in the direction of the inside of the case  200  is caught by the lowering of the cooperative operation bar  120 . When the portion of the horizontal portion  311 - 1  in the direction of the inside of the case  200  is pushed downward, the stop bar body  311  is rotated around the pin P, and the bottom end of the vertical portion  311 - 2  is rotated upward and is projected through the first opening  220  in the direction of the outside of the case  200 . 
     First protrusion bar units  140  and second protruding bar units  150  are installed in the column part  130 . Furthermore, the case body  210  includes second openings  230  formed below the first openings  220 , and reception depressions  240  depressed from the inside surface of the case body  210 . The first protruding bar units  140  and the second protruding bar units  150  may be installed at the same height, in which case the second openings  230  and the reception depressions  240  may be also installed at the same height. It will be apparent that the second protruding bar units  150  may be installed at lower locations than the first protruding bar units  140 , as shown in the drawings, in which case the reception depressions  240  may be formed at lower locations than the second openings  230 . 
     The first protrusion bar units  140  are disposed in a horizontal direction, and include respective first protruding bars  141  configured to be inserted into first seat depressions  132  formed in the column part  130 . The first protruding bars  141  are projected out of the case  200  via the second openings  230 . 
     The second protruding bar units  150  are disposed in a horizontal direction, and each include a second protruding bar  151  configured to be inserted into a corresponding one of the second seat depressions  133  formed in the column part  130  and a second elastic unit  152  provided between the bottom surface of the second seat depression  133  and the second protruding bar  151  and configured to press the second protruding bar  151 . In other words, the second protruding bars  151  of the second protruding bar units  150  press the inside surface of the case body  210 , are lowered in conjunction with the lowering of the column part  130 , and reach the height of the reception depressions  240  and are inserted into the reception depressions  240 . 
     The second openings  230  have a predetermined height in a height direction so that the first protruding bars  141  are selectively lifted and lowered in the state of being projected out of the second openings  230  while being lowered in conjunction with the lowering of the column part  130 . In other words, when the pointed head part  110  enters the inside of a tire, the column part  130  is lowered and the stop bar  310  is rotated by the cooperative operation bar  120 . In this case, when the displacement over which the column part  130  is lowered is insufficient, the angle around which the stop bars  310  are rotated is insufficient, and thus there is a case where the vertical portions  311 - 2  of the stop bars  310  are not projected in the direction of the outside of the case  200 . 
     In order to eliminate this concern, the second openings  230  through which the first protruding bars  141  pass have a specific height. In other words, when the pointed head part  110  enters the inside of a tire, the tire presses the first protruding bars  141 . The column part  130  is lowered by the lowering of the first protruding bars  141 , and the cooperative operation bar  120  is also lowered. Via this configuration, the angle around which the stop bars  310  are rotated can be sufficiently secured. 
     While being lowered in conjunction with the lowering of the column part  130  as described above, the second protruding bars  151  reach the reception depressions  240 , and are inserted into the reception depressions  240 . Via this configuration, the lowered column part  130  is fastened and prevented from being lifted back. 
     The cooperative operation bar  120  is intended to rotate the stop bars  310  as described above, and may be formed in a cross shape. Accordingly, four first openings  220  may be formed in the case  200  and four stop bars  310  may be also formed, and thus the stop bars  310  may be rotated through the respective first openings  220 . 
     Meanwhile, the second protruding bar units  150  provided in the column part  130  are installed at lower locations than the first protrusion bar units  140 , and the second protruding bar units  150  and the first protrusion bar units  140  are disposed in intersecting directions. For example, when the first protruding bars  140  are disposed in the front-back direction of the drawings, the second protruding bars  150  may be disposed in a left-right direction. 
     Furthermore, an elastic support portion  160 , such as a spring or the like, is disposed below the column part  130 , and elastically supports the bottom of the column part  130 . 
     Meanwhile, the vehicle stopping apparatus according to the present invention further includes an information communication unit (not shown) provided inside the case  200  and configured to store detection information regarding the lowering of the column part  130  and to transmit the detection information to a user. 
     In this case, the information communication unit includes a separate detection sensor, and transmits information related to the fact that the pointed head part  110  has been inserted into a tire and information related to the type of vehicle based on the degree of the insertion via the degree to which the column part  130  has been lowered. 
     In this case, the detection sensor is configured in the form of a load cell, is connected to the first protruding bars  140 , and detects the degree to which the first protruding bars  140  have been lowered. 
     While the embodiments of the present invention have been described with reference to the accompanying drawings, it will be appreciated by those having ordinary knowledge in the art to which the present invention pertains that the present invention may be practiced in other specific forms without changing the technical spirit or essential feature of the present invention. 
     Therefore, the above-described embodiments should be construed to be illustrative and non-limitative in all aspects, the range of the present invention described in the detailed description should be defined by the attached claims, and all alterations or modified forms derived from the meanings and ranges of the claims and equivalents thereto should be construed to fall within the scope of the present invention.
