to the fixing hole 42 a of the plate 42 using the hook . one end of moving portion 46 of a straight shaft 44 in which a rack gear 45 is formed is coupled to an inner center of the plate 42 , and one end of a guide plate 43 in which a long hole 43 a is formed is coupled to a hinge rib 42 b of one of both sides of an upper part and a lower part of the plate 42 , and the long hole 43 a of the guide plate 43 is inserted into and is moveably coupled to a guide rib 31 of the body 30 . the straight shaft 44 is inserted into and coupled to a bushing 32 coupled to the body 30 , and the rack gear 45 is installed to engage with a pinion gear 61 of a rotation shaft 60 installed in the body 30 . an elastic spring 50 is installed around the straight shaft 44 between the body 30 and the plate 42 , and a gravity center frame 100 or a front frame 201 of a treadmill 200 is coupled to a rear frame of the body 30 . a sensor 70 is fixedly installed by a fixing volt 71 at one side of the body 30 in which the rotation shaft 60 is installed . the sensor 70 is connected to a controller ( not shown ), and the controller is connected to a display unit and an input unit , and in the input unit , various data of a time , a striking speed , the number of times of striking , a weight upon striking , a time change amount upon striking , an impact amount , and a impact force are set , and the display unit distinguishably displays measured values of striking applied to the striking portion . the display unit is separately formed and is connected to the controller through a wired or wireless means . a rotation belt 204 is installed at the inside of a floor frame 202 of the treadmill 200 , a handle in which an angle adjustment button 213 is installed in an upper part thereof is installed at the left side of the treadmill 200 , a vertical shaft 210 is coupled to a lower side of the handle , and a spring 211 is installed between the vertical shaft 210 and a handle portion 212 . at the right side of the treadmill 200 , a handle having a treadmill on / off button and a front - rear movement button 213 a at an upper part thereof is installed , a vertical shaft 210 a is coupled to a lower part of the handle , and a spring 211 a is installed between the vertical shaft 210 a and the handle portion 212 a . an upper rail 203 is installed in an upper part of the treadmill 200 , a roller 221 of a support shaft 220 is inserted into a guide groove 203 a of the upper rail 203 , a ring 223 is installed at both sides of a support plate 222 coupled to the support shaft 220 , and a safety line 224 is connected to the ring 223 and is connected to both sides of a protective vest 225 . the plate 42 of a light metal material such as aluminum , or of a synthetic resin having high strength is provided in the striking portion 40 . the impact absorption member 41 is coupled to the plate 42 . the gravity center member 100 may be welded by disposing a connecting piece in the body 30 or may be fastened by a bolt and a nut to the body 30 . the kick exercise apparatus 10 can be moved and installed according to a location and position to install . when the impact absorption member 41 of the striking portion 40 is struck by punch or kick , the plate 42 moves inwardly and the central straight shaft 44 moves , and the pinion gear 61 installed in the rotation shaft 60 rotates by the rack gear 45 . in this case , the sensor 70 fixed to one side of the body 30 by the fixing volt 71 detects a rotation speed of the rotation shaft 60 and sends the rotation speed to a general display unit . in this case , at the same time with termination of striking to the striking portion 40 , the striking portion 40 is returned to an original position by a restoring force of the elastic spring 50 installed in the straight shaft 44 . the display unit is positioned at a location adjacent to the striking portion 40 . the display unit has an input unit , and an input operation can be manually / automatically performed . as described above , a striking mode of various methods according to a program can be set at the input unit , and various data such as a striking time period , the number of times of striking , a striking speed , a weight upon striking , a time change amount upon striking , an impact amount , and an impact force are previously input and set . when data are input to the input unit , in the display unit , a reference value is displayed with a numeral or a lamp , and a user can perform a striking mode of an initial state according to a preset value . thereafter , when a predetermined striking time period is terminated or when a striking exercise is terminated , exercise results such as a time , a striking speed , the number of times of striking , a weight upon striking , a time change amount upon striking , an impact amount , and an impact force are displayed in the display unit . if a performed result of a striking mode of an initial state is satisfied , a striking mode of a next step is performed , and if a performed result of a striking mode of an initial state is not satisfied , a striking mode of an initial state is again performed . in this way , striking is performed according to a preset mode and thus striking is repeatedly performed and striking of a next stage is performed according to the result . in the above process , after the kick exercise apparatus 10 according to an exemplary embodiment of the present invention is installed , the user can adjust a striking exercise amount according to a reference value that is set to the input unit , and as data of the striking exercise are displayed with numerals in a display unit , the user can easily recognize striking strength , accuracy of striking , a striking speed , the number of times of striking , a weight upon striking , a time change amount upon striking , an impact amount , and an impact force . although embodiments have been described with reference to a number of illustrative embodiments thereof , it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure . more particularly , various variations and modifications are possible in the component parts and / or arrangements of the subject combination arrangement within the scope of the disclosure , the drawings and the appended claims . in addition to variations and modifications in the component parts and / or arrangements , alternative uses will also be apparent to those skilled in the art .
