JP5752931B2 - Steps for getting on and off the vehicle - Google Patents

Description

  The present invention relates to a vehicle boarding / exiting step that is deployed on a vehicle step such as a bus, a one-box car, etc. so as to expand the area more than the above.

  Conventionally, in this type of vehicle, the step for getting on and off is already provided with the side part of the interior floor lowered one step, but the depth of the step is not sufficiently secured to secure a wide interior space (For example, refer to Patent Document 1).

JP 2007-90910 A (Steps for getting on and off the vehicle in FIGS. 1 and 2)

Therefore, when getting on and off, there is a problem that it is not easy to use because it is necessary to get on and off so as not to remove the foot while stepping on the step.
In addition, for reasons such as the recent decrease in the number of users of city buses, etc., it may be possible to operate the one-box car as a small bus, but in this case it may be necessary to meet the standards for use as a passenger vehicle. I had to increase the depth of the step.

  Therefore, in the present invention, even if an existing vehicle step does not conform to the standard of use as a passenger vehicle, an in-vehicle step that replaces the vehicle step on the vehicle step is replaced with the vehicle step ahead of the vehicle so that it conforms to the standard when getting on and off. The purpose of the present invention is to provide a vehicle getting-on / off step that extends to the outside and extends its depth length.

In view of the above problems, the vehicle getting-on / off step according to the present invention includes a stationary tread horizontally disposed at a rear portion in the depth direction on the vehicle step so as not to protrude outwardly on the existing vehicle step, and a tip of the vehicle step . A storage position where the front end is parallel to the upper part of the vehicle and the rear end overlaps in parallel on the fixed tread, and in front of the fixed tread so that the front end protrudes a predetermined length from the vehicle step to the front outside the vehicle. It is characterized by comprising an advancing / retreating plate provided so as to be reciprocally movable in parallel with the fixed tread between the overhanging positions connected on the same plane.
Specifically, a crank that can swing back and forth is provided on the vehicle step, a linkage is pivotally connected between the crank and the advance / retreat plate, and the axis of the advance / retreat plate in the linkage is the track of the advance / retreat plate. It is characterized in that it is slidably mounted in a guide groove formed along the shaft, and preferably the crank is connected to the drive device.

In short, according to the present invention, when the vehicle entrance / exit is opened by the door, the front end of the advance / retreat plate stored in an overlapping manner on the fixed tread horizontally disposed on the existing vehicle step protrudes a predetermined length from the vehicle step. In this way, by connecting to the front of the fixed tread on the same plane as this, it is possible to configure a step for getting on and off which is longer than the vehicle step and protrudes from the entrance to the outside of the vehicle.
Therefore, the depth of the boarding / exiting step can be lengthened to meet the usage standards for passenger vehicles, and the area of the boarding / exiting step can be expanded, so that safety during boarding / exiting can be ensured, and steps can be taken as in the past. You can get on and off without worrying about your feet.

  A crank that can swing back and forth is provided on the vehicle step, and a linkage is pivotally connected between the crank and the advance / retreat plate, and a pivot axis with the advance / retreat plate in the linkage is formed along the track of the advance / retreat plate. Because it is slidably mounted in the guide groove, the forward / backward tread plate can be controlled to reciprocate on a fixed track along the guide groove by swinging the crank back and forth, thereby always regulating the posture of the forward / backward tread plate. In particular, the movement of the advancing / retreating plate can be prevented during movement, and the reciprocating operation of the advancing / retreating plate can be performed safely and easily.

  Further, by connecting the crank to the driving device, the reciprocating movement of the advancing / retreating plate can be automated, and the troublesomeness of reciprocating the advancing / retreating plate near the entrance / exit is eliminated.

It is a perspective view which shows the overhang | projection state of the step for vehicle getting on / off concerning this invention. It is a partially omitted sectional view showing the overhanging state. It is a partially omitted sectional view showing the storage state.

An embodiment of the present invention will be described below with reference to the drawings.
The step for getting on and off the vehicle according to the present invention is provided such that the depth length can be expanded and contracted on the vehicle step S already provided at the lower part of the vehicle entrance and exit with a step on the in-vehicle floor F.
In this step for getting on and off, the fixed tread 1 that is horizontally disposed at the rear in the depth direction on the vehicle step S as shown in the illustrated example and the front end portion from the vehicle step S so as not to protrude outward on the vehicle step S. a storage position X rear end stepped parallel overlap on the front end of the fixed step board 1 with parallel at the tip over the vehicle step S without 2a protrudes forward as the outside, the front end than the vehicle step S The portion 2a is provided so as to be able to reciprocate in parallel with the fixed tread 1 between the front of the fixed tread 1 and an overhanging position Y connected on the same plane so that the portion 2a protrudes to the front outside the vehicle. It consists of an advancing / retracting board 2.

On the vehicle step S, front and rear left and right walls 3, 3 a, 4, 4 a which are parallel to the front and rear and the left and right of the vehicle step S are erected and the fixed tread 1 is horizontally supported at the center upper end of the rear wall 3 a.
The fixed tread 1 is parallel to the front end 1a between the front and rear walls 3 and 3a, the left and right end parallel to the left and right walls 4 and 4a, and the rear of the rear wall 3a along the kick of the vehicle step S. It consists of a thin plate having a trapezoidal shape in plan view having a rear end portion that is inclined, and an inclined wall 1b having a downward-falling shape is continuously formed at the front end portion 1a.

  Side walls 5 and 5a are formed on the left and right side edges of the fixed tread 1 from the front wall 3 to the rear of the rear wall 3a, and the front ends of the side walls 5 and 5a are fixed to the front wall 3 and The end portion is fixed to the rear wall 3a so as to protrude rearward beyond the left and right side portions formed with a lower height than the center portion supporting the fixed tread 1 in the rear wall 3a.

The advancing / retracting plate 2 has a lateral width longer than that of the fixed tread plate 1 and has a depth substantially equal to the distance between the front wall 3 and the rear wall 3a, and is continuously fixed to the front edge and the left and right side edges of the lateral rectangular plate. The U-shaped reinforcing frame constitutes a front end 2a and a side wall 2b of the advancing / retracting plate 2.
The rear side of the side wall 2b is formed so that the lower end edge is inclined downward toward the rear end, and on the inner side of the side wall 2b of the advancing / retreating plate 2, the inclination start end side and the end side at the downwardly inclined rear lower end edge are formed. Each has a trochanter 6 and 6a.

The advancing / retreating plate 2 is connected to a pair of left and right cranks 7 provided on the vehicle step S so as to be able to swing back and forth via an advancing / retracting mechanism as appropriate.
Each crank 7 shares a base end (crank) shaft 8, and the base end shaft 8 passes through the side walls 5, 5 a and is rotatably mounted between the left and right walls 4, 4 a.

  The advancing / retreating mechanism has a linkage 9 pivotally connected between the crank 7 and the advancing / retracting plate 2, and is a pivot 10 with the advancing / retreating plate 2 in the linkage 9, and an inclination start end having this as a support shaft. The trochanter 6 (pivot 10) on the side is slidably mounted in a guide groove 11 formed so as to penetrate along the trajectory of the advancing / retreating foot plate 2 on the side walls 5 and 5a of the fixed tread plate 1, and on the side walls 5 and 5a. The trochanter 6a on the inclined terminal side is slidably mounted in the same guide groove 11a which has been translated obliquely rearward and downward on the lower side.

  Since the crank 7 and the linkage 9 in the advancing / retreating mechanism having the above-described configuration are disposed in the gap between the front end 1a and the side walls 5 and 5a of the fixed tread 1 cut out at the left and right edges of the inclined wall 1b, The ream 9 can bend and stretch without any hindrance.

Then, the trochanter 6 (the pivot shaft 10) moves back and forth in the guide groove 11 by the bending and extending operation with the linkage 9 by swinging the crank 7 back and forth, so that the advancing / retreating plate 2 moves along the guide groove 11 to the retracted position X. And the overhanging position Y are reciprocated in parallel with the fixed tread 1 .
In the overhanging state of the advancing / retreating plate 2, the trochanters 6 and 6a are locked to the front ends of the guide grooves 11 and 11a on the rear side, and the rubber cushioning material 12 mounted on the upper end of the front wall 3 is on the side wall 2b on the front side. The horizontal state of the advancing / retreating plate 2 is maintained by supporting the lower end.

In order to automatically operate the advancing / retreating plate 2, the base end shaft 8 of the crank 7 is connected to the drive device 13 so as to be rotatable forward and backward.
This drive device 13 is provided with an electric motor and a speed reducer (not shown) on the left side of a motor base 14 that is erected on the left side of the left wall 4, and passes through the motor base 14 and protrudes toward the left wall 4. And a base end shaft 8 projecting outward (left side) from the left wall 4 is a parallel crank mechanism comprising a pair of cranks 15 and 15a having the same length and a linkage 16 pivotally connected between the cranks 15 and 15a. It is connected through.

As a result, the drive device 13 is activated and the drive shaft 13a rotates forward and backward, whereby the crank 15 of the drive shaft 13a swings back and forth, and the base shaft 8 is moved through the linkage 16 and the crank 15a. By making the same rotation as the drive shaft 13a, the advance / retreat plate 2 is deformed and moved.
In addition, stoppers 17 and 17a that touch the crank 15 are provided at each swing position of the crank 15 corresponding to the extended state and retracted state of the advancing / retreating plate 2 (see FIG. 1).

Next, the operation of the vehicle entry / exit step configured as described above will be described.
When the advancing / retracting plate 2 is housed in the room, the crank 15 of the drive shaft 13a tilts rearward and touches the stopper 17, and the crank 7 is placed on the vehicle step S via the linkage 16, the crank 15a, and the base shaft 8. I'm putting it back.

  As a result, the crank 7 and the linkage 9 connected thereto extend rearward, and the trochanter 6 (the pivot shaft 10) and 6a are positioned at the rear ends of the guide grooves 11 and 11a to fix the advancing / retreating plate 2 The vehicle step S is retracted to the retracted position X on the tread plate 1, the rear end portion is overlapped on the front end portion 1 a of the fixed tread plate 1, and the front end portion 2 a of the advancing / retreating step plate 2 is not projected out of the vehicle step S. The storage is arranged on the fixed tread board 1 above. Therefore, in the retracted state of the advancing / retreating plate 2, there is no problem in opening and closing the vehicle door.

In order to project the advancing / retracting plate 2 out of the vehicle from the retracted state, the drive device 13 is operated and the base shaft 8 is rotated via the cranks 15 and 15a and the connecting rod 16 to thereby move the crank 7 in the rearward state. Is swung forward.
As a result, the crank 7 and the linkage 9 are bent forward, and the trochanters 6 (pivotal shafts 10) and 6a are positioned at the front end located below the rear ends of the guide grooves 11 and 11a. Arranged at the forward overhanging position Y, the advancing / retreating step board 2 and the fixed tread board 1 are connected to the front and rear on the same plane, and the step for getting on and off is ahead of the entrance and exit from the vehicle step S in a state where the depth is longer than the vehicle step S. Project outside the car.

In such a state, the driving device 13 stops, and the crank 15 falls forward and touches the stopper 17a.
Thus, the boarding / exiting steps (tread plates 1 and 2) developed forward in front of the entrance on the vehicle step S are used as foot joints that are longer in depth than the vehicle step S and expanded in area.

  In order to store the extended and retracted stepping plate 2 in the overhanging state, the driving device 13 is operated to swing the proximal shaft 8 backward in the reverse direction to operate the forward and backward stepping plate 2 in the reverse order. Then, it is stored in multiple layers via the fixed tread 1 on the vehicle step S.
