[0026]

[0027] In more detail,

[0028] the frame 100 includes: a mounting plate 110 being formed at right angle and having an L-shaped cross-section to correspond to the shape of an edge of the structure 700 such as a wall or a column so that the frame 100 can be stably fastened; a top protrusive holder 120 and a bottom protrusive holder 130 protruding outward in shape from the upper and lower ends of the front of the mounting plate 110 to hold the rotary shafts 300 inserted in the rotary rollers 200 over the front side of the mounting plate 110 and to form a shock-absorbing space that can attenuate shock applied to the structure 700 and the impacting object 800 in a collision of the impacting body 800 with the structure 700; strap holes 140 formed through upper and lower portions of the mounting plate 110 to pass the connection straps 600 that can strongly couple the frames 100 when the frames 100 are fastened to the structure 700; bolt holes 150 formed between the strap holes 140 of the mounting plate 110 so that the frame 100 can be fastened to an edge of the structure 700 by bolts 620; and a sensor seat 160 protruding upward from a side on the top of the top protrusive holder 120 and having a T-shaped recession 161 so that the sensor unit 500 that can sound an alarm by sensing approach of an object can be fastened to the top of the frame 100, in which top rotary shaft grooves 121 and bottom rotary shaft grooves 131 are formed in oblong shapes respectively on the bottom of the top protrusive holder 120 and the top of the bottom protrusive holder 130 so that the upper and lower ends of the rotary shafts 300 are inserted therein and the rotary shafts 300 can smoothly horizontally rotate. Further, elastic members holes 170 are formed at first sides from the top rotary shaft grooves 121 and the bottom rotary shaft grooves 131 so that the elastic members 400 that can contract or stretch when the impacting object 800 collides with the structure 700 can be inserted in the frame 100. Second sides of the top rotary shaft grooves 121 with the elastic body holes 170 at the first sides, unlike the bottom rotary shaft grooves 131, are open so that the rotary shafts 300 can be inserted from the front of the top protrusive holder 120, and protrusive retainers 122 protruding inward are formed inside the open sides to prevent separation of the upper ends of the rotary shafts 300 inserted in the top rotary shaft grooves 121.

[0029]

[0030] The rotary rollers 200 are formed in a cylindrical shape to be able to attenuate shock that is applied to the structure 700 and the impacting object 800 by minimizing a contact surface with the impacting object 800 by rotating in the movement direction of the impacting body 800 when the impacting body 800 hits against the structure 800, and each have a central hole 210 longitudinally formed through the center thereof to receive the rotary shafts 300.

[0031] The sensor unit 500 includes: a sensor 510 that can sense an approach of an object; an alarm 520 that is disposed on the top of the sensor 510 and can sound an alarm when an object approaches; a switch 530 that is disposed on a side of the sensor 510 to control whether to operate the sensor 510; a coupler 540 that protrudes downward from the bottom of the sensor 510 and has a locking ball hole 541 at the center; a locking ball 541 that is formed in a spherical shape corresponding to the diameter of the locking ball hole 541 to be inserted in the locking ball hole 541 of the coupler 540 so that the sensor 510 can rotate left and right to correspond to an object that approaches at various angles; an height adjuster 560 that protrudes downward from the bottom of the locking ball 550 and can determine the vertical position of the sensor 510 coupled to the locking ball 550; and an insert 570 that has a T-shaped cross-section corresponding to the recession 161 to be inserted into the recession 161 of the sensor seat 160 of the frame unit 100 so that the sensor unit 500 is integrally coupled to the frame unit 100.

[0032]

[0033] The connection straps 600 can fasten a plurality of frame units 100 by being inserted in the strap holes 140 formed through the mounting plates 110 of the frame units 100 and each have a Velcro tape 610 on the front and rear sides of both ends so that the frames 100 integrally connected by the connection straps 600 can be stably fixed on the outer side of the structure 700.

[0034]

[0035] As an embodiment,

[0036] when a plurality of frame units 100 is fastened on the edges of the structure 700 that is a rectangular wall or column, as shown in FIG. 2, the connection straps 600 are inserted through the oblong strap holes 140 formed at the upper and lower portions of the mounting plates 110 of the frame units 100, thereby integrally connecting the frames 100. Further, as shown in the detailed view of FIG. 7, the Velcro tapes 610 on the front and rear sides of both sides of the connection straps 600 are attached to each other, whereby the frames units 100 integrally connected by the connection straps 600 can be fastened on the edges of the structure 700. When a single frame unit 100 is fastened on an edge of the structure, as shown in the detailed views of FIGS. 2 and 8, bolts 620 are inserted in the structure 700 through the bolt holes 150 formed through the mounting plate 110, whereby the frame unit 100 can be stably fastened.

[0037]

[0038] The rotary rollers 200 can be fitted on the rotary shafts 300 by the central holes 210 longitudinally formed through the centers of the rotary rollers 200. The upper ends and lower ends of the rotary shafts 300 are inserted between the top protrusive holder 120 and the bottom protrusive holder 130 of the frame unit 100 fastened on the structure, so the rotary shafts 300 can be coupled over the front of the frame unit 110 with the rotary rollers 200 fitted thereon. That is, the lower ends of the rotary shafts 300 are inserted first into the bottom rotary shaft grooves 131 formed on the top of the bottom protrusive holder 130 and then the upper ends of the rotary shafts 300 are inserted into the top rotary shaft grooves 121 formed on the bottom of the top protrusive holder 120 from the open sides, whereby the rotary shafts 300 can be coupled over the front of the frame unit 100. In this state, the upper ends of the rotary shafts 300 are fixed by the protrusive retainers 122 protruding inward inside the open sides of the top rotary shaft grooves 121, so the rotary shafts 300 cannot be separated forward from the frame unit 100.

[0039] When the impacting object 800 such as a vehicle or freight that is being carried hits against the rotary rollers 200 coupled with the rotary shafts 300 inserted therein over the front side of the frame unit 100, as shown in FIG. 9, the rotary rollers 200 with the rotary shafts 300 inserted therein are rotated about the rotary shafts 300 in the movement direction of the impacting object 800, as shown in FIGS. 5 and 6, so the contact area with the impacting object 800 can be minimized. Further, the rotary shafts 300 inserted in the rotary rollers 200 are horizontally moved between the top protrusive holder 120 and the bottom protrusive holder 130 by the pressure applied to the outer sides of the rotary rollers 200, so the shock that is applied to the structure 700 and the impacting object 800 can be attenuated. That is, as shown in the detailed views of FIGS. 5 and 6, by the pressure applied to the outer sides of the rotary rollers 200, the upper and lower ends of the rotary shafts 300 press first sides of the elastic members 400 inserted in the elastic member holes 170 of the frame unit 100, so the elastic members 400 can contract. Accordingly, the rotary shafts 300 are horizontally moved in the top rotary shaft grooves 121 and the bottom rotary shaft grooves 131 in which the upper and lower ends of the rotary shafts 300 are inserted, so the shock that is applied to the structure 700 and the impacting object 800 can be absorbed.

[0040]

[0041] Since the insert 570 is inserted in the recession 161 of the sensor seat 160 of the frame unit 100, as shown in FIG. 3, the sensor unit 500 can be fastened to a side on the top of the top protrusive holder 120 of the frame unit 100. Further, as shown in the detailed view of FIG. 9, the sensor 510 senses that a vehicle or freight that is being carried approaches the structure 700 and the alarm 520 sounds an alarm, so a driver or a worker can recognize approach of the vehicle or the freight, whereby it is possible to prevent a collision of the vehicle or the freight that is being carried with the structure 700. Further, as shown in the detailed view of FIG. 3, since the spherical locking ball 550 is inserted in the locking ball hole 541 formed at the center of the connector 540 and the locking ball hole 541 rotates forward/backward and left/right on the locking ball 550, as shown in the detailed view of FIG. 6, the sensor 510 of the sensor unit 500 can effectively deal with an object approaching at various angles.

[0042] The configurations and operation principles of the sensor 510 and the alarm 520 can be inferred from the related art, so they are not described herein.
