That is, the relationship between the first footrest corresponding portion 2213 and the second footrest corresponding portion 3213 is shown in Fig. The second footrest-corresponding contact portions 3213 are each defined by the rear end side of the two second footrest connection ribs 322b and the rear end of one or more predetermined number of second footrest main ribs 322a disposed therebetween, A second footrest main rib 322a is disposed between the second footrest connection ribs 322b and a second footrest connection rib 322b and a second footrest main rib 322a are alternately arranged at a ratio of 1: And the first footstep continuous incline contact portion 2213 also has a corresponding width and the first footstep continuous incline contact portion 2213 is accommodated in the second foot corresponding portion 3213 thus partitioned, (See Fig. 20 (a)).

A plurality of second scaffolding main ribs 322a may be disposed between the second scaffold connection ribs 322b to form a structure that provides an extended space region of the second scaffold-corresponding contact portion 3213 (See Fig. 20 (b)). However, when the width between the second foot connecting ribs 322b is excessively widened, the scraping effect through the interlocking structure or the engaging structure is lowered, so that it is desirable to have a drainage relationship in which an appropriate number of the footrest connecting ribs 322b is arranged.

A second footrest corresponding portion 3213 partitioned by the second footrest connection rib 322b and / or the second footrest main rib 322a, a first footrest corresponding to the first footrest corresponding to the first footstep continuous An interlocking structure is formed with respect to the first footrest 210 and the second footrest 320, which are at least partially overlapped when projected on a plane parallel to the indoor floor of the vehicle through the engagement structure of the inclined contact portions 2213 The height difference between the first footrest and the second footrest is minimized when viewed on a plane perpendicular to the ground, thereby minimizing the step difference in the connection area of the footrests, thereby eliminating safety accidents and inconveniences have.

The second scaffolding tilting unit 340 includes a second scaffold hinge body 341, a second scaffold hinge body holder 343, and a second scaffold hinge body connecting member 345. One end of the second footrest hinge body 341 has a hinge body coupling portion 3411 at the one end and a hinge body coupling portion 3415 at the other end and a hinge body coupling portion 3415 between the hinge body coupling portion 3411 and the hinge body coupling portion 3415, (3413). The hinge body coupling portion 3411 is connected to the second scaffold body coupling portion 3211 and the hinge body coupling portion 3415 is connected to the second scaffold hinge body holder 343 through the second scaffold hinge body coupling member 345 do. The hinge body connecting portion 3415 of the second scaffold hinge body main portion 3210 and the second scaffold hinge body holder 343 are formed to protrude upward and have a shape of? So that a smooth link operation is performed, Thereby enabling a compact arrangement of the components of the device. Through this structure, the second foot plate 320 can achieve a predetermined tilting rotation hinge operation with respect to the horizontally moving carrier body 310.

The horizontal rotation axis C1 constituting the tilting hinge operation of the second foot plate 320 is mounted on the second foot hinge body connecting member 345 which is the connecting shaft of the hinge body connecting portion 3415 and the second foot hinge body holder 343 And is formed to protrude upward from the hinge body connecting part 3415 and the second scaffold hinge body holder 343 and is formed at the center of the axis of the second scaffold hinge body connecting member 345 above the shape area of? A gap is formed between the horizontal rotation axis C1 and the support roller 240 by a predetermined distance in the direction in which the foot module 20 is drawn out.

In addition, the footing module 20 of the present invention is configured such that the first footstep module 200 and the second footstep module 300 move together with respect to a predetermined moving region, and then the second footstep module is pulled out or drawn alone . The connection support means 260 may be disposed on the side of the first scaffolding module 200 and may be connected to the connection support means 260 through the connection support means 260. [ The retaining pin 311 as a possible engaging means is disposed in the second scaffolding module 300.

That is, the latching pin 3111 is mounted on one side of the second scaffolding module 300, and the connection support means 260 is coupled to the first scaffolding module 200, (Not shown).

The connection support means 260 is rotatably coupled to the first scaffolding module 200. More specifically, the connection support means 260 is coupled to the rear support frame 211 on the inner one side of the lower support frame 211 of the first scaffolding module 200 As shown in Fig. The connection support means 260 includes a hook link 262 and a hook actuating link 263. The hook link 262 is engaged with the hooking pin 311 so that the first scaffolding module 200 is pulled out together with the second scaffolding module 300 and the hook operation link 263 is rotated together with the hook link 262 .

The rotation of the hook link 262 is made by the hook actuating link 263, and the hook actuating link 263 is actuated by the pressing block E. [ The pressurizing block E is mounted on the guide frame 411 (see Fig. 25) of the drive unit 40 described below.

A hook portion 262-1 is formed at the end of the hook link 262, and the hook portion 262-1 can be engaged with the hooking pin 311. [ The hook operation link 263 is pressed by the separate pressing block E as the first scaffolding module 200 is pulled up to the end of the projecting support portion 102 so that the hook link 262 is disengaged from the engagement pin 311 . The hook link 262 and the hook actuating link 263 are all coupled to the connection support shaft 261 mounted on the first scaffolding module 200 and configured to rotate about the connection support shaft 261, And may be configured to rotate integrally through a mechanical element such as a connecting pin (not shown).

27 and 28, when the second scaffolding module 300 is moved in the direction in which the second scaffolding module 300 is drawn out by the drive unit 40, the first scaffolding module 200 is connected to the connection support means 260 The second scaffolding module 300 and the second scaffolding module 300 are moved in a straight line direction. 27, since the hook link 262 of the first scaffolding module 200 is held in engagement with the retaining pin 311 of the second scaffolding module 300, the second scaffolding module 300 The first scaffolding module 200 moves simultaneously. Since the first scaffold module 200 is configured to be extended to the end of the protruding support portion 102 by mounting a separate stopper (not shown) in the frame unit 10, The first scaffolding module 200 can not move forward and is restrained in a stationary state when the scaffolding module 300 linearly moves to the end of the protruding support portion 102 together with the scaffolding module 300. [

28, when the first scaffolding module 200 and the second scaffolding module 300 are moved to the end of the protruding support portion 102, the hook actuating link 263 is separated from the separate press block E, And simultaneously the hook link 262 is also rotated integrally in the clockwise direction.

When the hook link 262 is rotated in the clockwise direction, the engaging state of the hook link 262 and the engaging pin 311 is released. Therefore, as shown in FIGS. 29 and 30, In the case where the second footstep module 300 is moved in the direction to be continuously drawn out by the drive unit 40, only the second footstep module 300 is moved in the direction to be drawn out. That is, since the first scaffolding module 200 is held in a state of being pulled and restrained by the stopper, and the engaged state of the hook link 262 and the engagement pin 311 is released, Only the second scaffolding module 300 is pulled out by the drive unit 40 in a stopped state.

At this time, the pressing block E can be coupled to the side surface of the guide frame 411 of the driving unit 40, and the hook link 262 can be engaged with the side surface of the guide frame 411, And can be elastically supported by a spring (not shown).

In a state where the first scaffolding module 200 is extended to the end of the protruding support portion 102 together with the second scaffolding module 300 by the connection support means 260, The second footstep module 300 may be unintentionally drawn or vibrated while the second footstep module 300 is drawn out of the vehicle because the linear movement is restricted in the direction of being pulled out by the stopper, have. Therefore, the connection support means 260 according to an embodiment of the present invention can prevent the connection of the first scaffold module 200 with the first scaffold module 200 in a state in which the first scaffold module 200 is extended to the end of the protrusion support portion 102, . ≪ / RTI >

To this end, the connection support means 260 includes a follower link 264 rotatably coupled to the first scaffolding module 200 and adapted to be engaged with a separate ratchet gear R, a follower link 264, And a follower actuating link 265 which is integrally pivotally coupled and resiliently rotatable in conjunction with movement of the second scaffolding module 300. At this time, the follower link 264 and the follower operation link 265 can be pivotally coupled together with the above-described connection support shaft 261, and the ratchet gear R can be coupled to the guide frame 411 of the drive unit 40, Or the like.

The follower actuating link 265 is configured to be resiliently attached to one surface of the second scaffolding module 300 by a separate torsion spring (not shown). 27 and 28, when the first scaffolding module 200 and the second scaffolding module 300 move at the same time and no relative movement occurs between them, the follower operation link 265 moves to the second 29, only the second scaffolding module 300 is moved in a state where the first scaffolding module 200 is stopped, and relative movement is performed in a direction in which the second scaffolding module 300 moves away from the first scaffolding module 300 The follower actuating link 265 is rotated in the direction in which it closely contacts the second scaffolding module 300 by the elastic contact force of the torsion spring. At the same time, the follower link 264 is rotated so that the follower link 264 is engaged with the ratchet gear R of the guide frame 411.

29, when the first footstep module 200 is stopped and the second footstep module 300 is moved upward, that is, when the second footstep module 300 is pulled out, the follower operation link 265 is tilted The second footplate module 300 is rotated in the direction of elastic contact with the second footplate module 300 in the clockwise direction by the elastic force of the spring. At the same time, the follower link 264 rotates integrally in the clockwise direction. As the follower link 264 rotates in the clockwise direction, its end is engaged with the ratchet gear R. [

Thus, as the follower link 264 is engaged with the ratchet gear R, the first scaffolding module 200 is restrained in the direction in which it is pulled.

Accordingly, the first scaffolding module 200 is simultaneously drawn to the end of the protruding support portion 102 together with the second scaffolding module 300 by the connection supporting means 260, and is moved in the direction of drawing or pulling in this state. So that it is stably fixed. The second scaffolding module 300 is drawn out of the vehicle by the drive unit 40 in a state where the first scaffolding module 200 is stably fixed.

The rear end of the second scaffolding module 300 presses the follower operating link 265 and the rear end of the second scaffolding module 300 pushes the follower operating link 265. When the second stepping module 300 is retracted, The operation link 265 is rotated counterclockwise. When the follower operation link 465 rotates in the counterclockwise direction, the follower link 264 that rotates together with the follower operation link 465 also rotates integrally in the counterclockwise direction, so that the follower link 264, The engagement of the first footstep module R is released, so that the first footstep module 200 can also be retracted together.

Also, in such a rearward pulling-in process, the second scaffolding module 300 is pulled in by a continuous process of contact and non-contact between the pressing block E and the hook operation link 263 so that the hooking pin 311 reaches a predetermined position The contact engagement state between the hook link 262 and the engagement pin 311 can be restored by the rotation of the hook link 262 in the counterclockwise direction.

Meanwhile, the pedestal unit 20 according to an embodiment of the present invention may be configured to perform a predetermined pivoting operation for stable contact with the upper surface of the flat foam (Q) in a state of being drawn out from the frame unit 10 to the outside of the vehicle . That is, in the drawing process of the footing unit 20, the footing plate is rotated by a certain angle in a predetermined upward direction and then can be rotated downward by its own weight, And the upper surface of the foot unit 20 forms a downward inclined surface toward the platform Q. [

Meanwhile, the footrest unit 20 may be constructed in such a manner that one footstep module is pulled in or pulled out as described above, or may be configured in a multi-stage fashion in which two footstep modules are sequentially pulled in or pulled out. As shown in FIG. Hereinafter, for the sake of convenience of explanation, a description will be given of a structure in which the scaffolding unit 20 is rotated with respect to the second scaffolding module 300.

The second scaffolding module 300 includes a carrier plate 310 linearly moved by the drive unit 40 and a second plate spring 310 rotatably coupled to the front of the carrier plate 310 about the horizontal rotation axis C1. And the second foot plate 320 is configured to rotate about the horizontal rotation axis C1 in the process of being drawn out from the first foot plate module 200. [

The second scaffolding 320 is supported and drawn by a support roller 240 coupled to a support frame 210 of the first scaffolding module 200 in the process of being drawn out from the first scaffolding module 200 The carrier plate 310 and the second plate 320 may be separated from each other as shown in FIG. 21 so that the second scaffold 320 can be drawn out simultaneously with a predetermined rotating operation, that is, a predetermined upward rotation and downward rotation, And the second foot lifter 320-1 is formed at the rear lower end coupled thereto. That is, the second footrest lifter 320-1 is formed on the lower surface of the second footrest 320, and the second footrest lifter 320-1 is in contact with the support roller 240.

The second footrest lifter 320-1 is configured such that when the second footrest 320 is pulled out of the first footstep module 200 the second footrest 320 is rotated by the horizontal rotation axis C1 formed by the second footrest tilting unit 340 ) To a predetermined center of rotation. The second foot lifter 320-1 includes a lifter uphill 320-1a, a lifter downhill 320-1b and a lifter peak 320-1c, 320 and a plane including the direction in which the foot module 20 is drawn out from the front end of the second foot plate 320 toward the rear end of the second foot plate, The height of the time increases. The lifter downhill 320-1b has a smaller height from the tip of the second footplate 320 toward the rear end of the second footplate 320. The lifter peak 320-1c has the lifter uphill 320-1a and 320-1b, And a lifter peak 320-1c disposed between the lifter downhill 320-1b and connecting the lifter uphill 320-1a to the lifter downhill 320-1b. That is, the lifter peak 320-1c is disposed between the lifter uphill 320-1a and the lifter downhill 320-1b to prevent a sudden change in rotation of the second lifting plate, .

Accordingly, the second footplate 320 is supported by the support rollers 240 in the process of being drawn out from the first footplate module 200 to the outside, and the upward movement is performed at a predetermined angle And when the second foot plate 320 reaches the vicinity of the upper portion of the platform Q, it gradually rotates downward due to its own weight. That is, the second foot plate 320 does not rotate downward in a state where the second foot plate 320 is drawn out but turns in a predetermined upward direction and downward direction in a process of being drawn out. Likewise, even when the second footplate 320 is retracted by the drive unit 40, the second footplate 320 is suddenly rotated upwards at a predetermined angle along the profile of the second footplate lifter 320-1 formed on the lower end face, . According to this structure, the pulling-out and pulling-in operation of the second foot plate 320 can be made more smooth and stable.

Meanwhile, the second footrest 320 may further include a second footrest supporting roller receptor 323 according to the present invention. The second scaffold support roller receptor 323 is formed on the lower surface of the second scaffold 320 to receive the support roller 240 when the second scaffold 320 is drawn out of the first scaffold module 200, The second scaffold support roller receptor 323 is disposed at the rear end in contact with the lifter downhill 320-1b. The second scaffold supporting roller receptor 323 is formed in a groove structure so as to have a structure closer to the body 101 than the lifter downhill 320-1b, The support roller 240 can be received in the second scaffold support roller receptor 323. The support rollers 240 are accommodated in the second scaffold support roller receptors 323 so that the stiffness of the second scaffolds 320 can be maintained and the tilt angle of the second scaffolds 320 can be smoothly formed .

The second footrest supporting roller receptor 323 may be spaced apart from the horizontal rotation axis C1 formed at the second footrest tilting unit 340 by a predetermined distance dr. The support rollers 240 can be separated from the first and second scaffold support roller receivers by the distance between the second scaffold support roller receptors and the second scaffold support rollers, The torque load load applied to the support rollers 240 to the second scaffolding tilting unit 340 may be reduced to increase durability and stability when accommodated in the scaffold support roller receptor.
