Description

  The present invention relates to a handrail in a two-fold door provided at the entrance of a vehicle such as a bus.

Conventionally, in this type of folding door, on the inner side surface (facing the inside of the vehicle in the closed state) of the hand door, there is a handrail inclined upward toward the inside of the vehicle when the folding door is fully opened (folded back into two). In particular, passengers such as children and elderly people boarded on a handrail as a support when stepping on the entrance / exit steps located higher than the ground level when riding.
However, the folding door is on the entrance / exit step, and the handrail is inclined between the open end and the hinge end on the inner side of the hand door, and does not protrude beyond the width of the hand door. Therefore, in order to grasp the handrail, it is inconvenient for the passenger to step on the vehicle step in a half body posture and to grasp the handrail at the same time.
In order to solve such a problem, Patent Document 1 provides an arm that swings left and right in conjunction with the opening / closing operation of the folding door on the inner surface of the hand door in the two-fold door provided at the entrance of the vehicle. A vertical bar-shaped grip that is disposed on the inner side of the hand door in the closed state of the folding door and protrudes outward from the open end of the hand door in the opened state of the folding door is disclosed.
According to this grip, by opening the folding door, the grip can be protruded outward from the entrance and exit, and a grip that serves as a support for getting on and off can be placed in front of the entrance and exit. You can ride without difficulty by stepping on the entrance / exit with the grip in front of you.

JP 2003-247358 A

However, since the above grip is formed in the shape of a vertical bar, when the folding door is opened, it only protrudes outward in parallel with a predetermined interval from the opening side end of the hand door. Although it is effective as a support for stepping up to a vehicle step higher than the ground, it could not be a support until getting ready after getting into the vehicle or when getting off the vehicle.
Therefore, in the present invention, the handrail that swings up and down in conjunction with the opening / closing operation of the folding door inside the hand door and passes obliquely from the inside of the vehicle through the entrance / exit to the lower outside of the vehicle with the folding door open. The purpose of this is to further increase the safety of getting on and off by using the handrail.

In view of the above problems, the handrail of the present invention is a two-fold door provided at the entrance of a vehicle, and is arranged in parallel to the inner side surface of the hand door and parallel to the inner side surface in conjunction with the opening / closing operation of the folding door. A balustrade that swings up and down is maintained, and the balustrade stands upright vertically when the folding door is closed, and the lower end when the folding door is opened protrudes obliquely downward from the open end of the hand door. It is characterized by the fact that it is tilted.
In addition, on the inner side of the hand door, a coaster that pivots above the balustrade and that can reciprocate in the lateral direction is provided, and is linked to an operating mechanism that moves the coaster back and forth in conjunction with the opening and closing operation of the folding door. The balustrade and the coaster are characterized in that they are linked via a link mechanism that swings the balustrade up and down in accordance with the forward and backward movement of the coaster.

In short, according to the present invention, when the folding door is opened, the balustrade is tilted on the inner side surface of the hand door, and the lower end of the balustrade protrudes to the outside of the entrance / exit, thereby allowing the balustrade to pass through the entrance / exit from the inside of the vehicle. It can be slanted downward to the outside, so that it is always possible to use the balustrade as a support for walking and getting on and off safely when getting on and off the vehicle.
The balustrade stands upright in the closed state of the folding door, swings up and down while maintaining the parallel state with the inner surface of the hand door in conjunction with the opening and closing operation of the folding door, and the lower end when the folding door is opened is the hand Since the door is projecting obliquely downward from the open end of the door and tilted, the balustrade is always parallel to the inner surface even if the balustrade swings during the folding door opening / closing operation. Since it rotates above, it is safe without involving passengers in the car.
In addition, when the folding door is closed, the balustrade fits upright on the inner side of the hand door and can be stored and held in the car well, so it is not exposed to the wind and rain at all times and will not get dirty. Without having to do so, you can use the balustrade as a support for walking along when getting on and off.

  On the inner side of the hand door, a coaster that pivots on top of the balustrade and reciprocates in the lateral direction is provided, and the coaster is linked to an operating mechanism that moves forward and backward in conjunction with the opening and closing operation of the folding door. And the coaster are linked via a link mechanism that swings the balustrade up and down according to the advancement and retreat of the coaster, so that the operation mechanism advances and retracts the coaster according to the opening / closing operation of the folding door. Thus, the balustrade can be swung up and down, so that a dedicated drive source for moving the balustrade at the entrance / exit is unnecessary, and the mechanism for operating the balustrade can be made relatively compact.

An embodiment of the present invention will be described below with reference to the drawings.
The handrail according to the present invention is arranged in parallel with the inner side surface D1 of the hand door Da in the two-fold door FD provided at the entrance G of the vehicle such as a bus, and the inner side surface D1 in conjunction with the opening / closing operation of the folding door FD. A balustrade 1 that swings up and down while maintaining a parallel state is provided. The balustrade 1 stands upright in the closed state of the folding door FD, and the upper end 1a when the folding door FD is opened is connected to the hinge side of the hand door Da. The lower end 1b protrudes obliquely upward from the end a1, and the lower end 1b protrudes obliquely downward from the open side end a of the hand door Da and tilts.

The folding door FD connects the hand door Da and the fishing door Db so as to be able to bend and stretch at the hinge H on the step S of the entrance / exit G, and pivotally attaches one side edge (fishing source) of the fishing door Db to the vehicle. Then, by connecting an automatic opening / closing device (not shown) mounted on the vehicle to the fishing door Db and swinging the fishing door Db, the fishing door Db and the hand door Da are bent and extended, and the entrance G is opened. Open and close.
Although not shown in the drawings, the upper and lower ends (step S) of the entrance / exit G are formed with concave grooves that are vertically parallel to the lateral sides thereof, and the open side end (one side edge) a of the hand door Da is formed in each of the concave grooves. The groove running bodies projecting from the upper and lower ends are slidably mounted, and as shown in FIGS. 1, 4, 6, and 8, the open side end a side of the hand door Da is always on the same line (on the axis of the groove). Equivalent) The open / close state of the folding door FD is regulated so that it moves back and forth linearly.

The folding door FD is not limited to the illustrated example, and may be provided on both the left and right sides of the entrance / exit G so as to be double-opened. In this case, of course, the handrail is applied to each hand door Da of the left and right folding doors FD. Is provided.
The folding door FD may be manually opened and closed.

The balustrade 1 includes a square bar-shaped support rod 2 having a predetermined length, a round bar formed in a substantially U-shape, and a longitudinal portion that is the same length and parallel to the support rod 2 and each end of the support rod 2 And a handrail rod 3 provided with short portions (corresponding to upper and lower ends 1a and 1b) fixed at right angles to the portion.
And the balustrade 1 stands upright (lengthwise) so that the support rod 2 is along the hinge side end a1 side of the hand door Da, and the lower part of the window W formed in the upper half on the inner surface D1 of the hand door Da Is pivotally attached to the front part of the bracket 4 straddling the lateral width direction near the hinge side end a1 (hereinafter referred to as a pivot 2a).
Thereby, the balustrade 1 is attached to the inner surface D1 of the hand door Da so as to swing up and down while always maintaining a parallel state with the inner surface D1.

On the inner side surface D1 of the hand door Da, below the window W, a balustrade sunk device 5 that swings the balustrade 1 up and down according to the opening degree of the folding door FD is attached.
The balustrade submerging device 5 has a base 6 joined and fixed on an inner surface D1, and a pair of upper and lower linear rails 7 and 7a are horizontally arranged in the lateral direction (the width direction of the hand door Da) below the upper surface of the base 6. .

The linear rails 7 and 7a are installed between support pieces 8 and 8a which are erected on the base 6 in the lateral direction, and cylindrical sliders 9 and 9a are slidably mounted using the support pieces 8 and 8a as a stopper. doing.
On the sliders 9 and 9a, a substrate 10 having a predetermined shape is placed and fixed to form a coaster 11 that can reciprocate in the lateral direction.

The coaster 11 is linked to an operation mechanism unit 12 that moves it back and forth in conjunction with the opening / closing operation of the folding door FD.
The balustrade 1 and the coaster 11 are connected via a link mechanism 13 that swings the balustrade 1 up and down in accordance with the forward and backward movement of the coaster 11.

The operation mechanism 12 moves the coaster 11 forward and backward along the linear rails 7 and 7a in conjunction with the opening / closing operation of the folding door FD, and on the inner side D2 of the fishing door Db, the hinge side end b An output rod 14 whose tip protrudes from the hinge side end b toward the hand door Da (left side in the figure) is horizontally arranged.
Then, the front end of the output rod 14 and the front end of the substrate 10 in the coaster 11 are pivotally connected via a connecting rod 15 in a plan view.
Thereby, the tip of the output rod 14 is displaced on a predetermined circular orbit by opening / closing (bending / extending) operation of the folding door FD, so that the coaster 11 is moved forward and backward along the linear rails 7 and 7a via the connecting rod 15.

The link mechanism portion 13 includes a flange 16 pivotally attached at a substantially middle portion of the base 6 and a short link 17 that pivotally connects the upper end of the flange 16 and a portion below the pivot 2a of the support rod 2. The long hole 18 is drilled in the vertical direction at the rear end of the substrate 10 of the coaster 11 and slidably mounted with a trochanter (not shown) provided at the lower end of the flange 16.
Then, the coaster 11 is reciprocated to bend and extend the rod 16 and the linkage 17 of the link mechanism 13, support the balustrade 1 (support rod 2) upright in the bent state, and tilt the support rod 2 in the extended state. It is made to push up and support this.

Also, at the appropriate position on the upper surface of the base 6, when the rod 16 and the linkage 17 are bent (when the folding door FD is closed), a stopper 19 for abutting and supporting the upper right side of the rod 16 whose upper end is inclined to the right side, At the time of extension of 16 and the linkage 17 (when the folding door FD is opened), there is provided a stopper 20 that abuts and supports the upper left side of the flange 16 whose upper end is inclined to the left side.
In addition, in the vicinity of the stop 20, the upper end is tilted to the left so that it does not rattle even if the passenger grabs the rail 1 that is tilted by the extension of the fence 16 and the linkage 17 when the folding door FD is opened. A holder 21 for abutting and supporting the upper front of 16 is disposed opposite to the base 6.

Further, a roller 22 that rolls on the upper surface of the base 6 during the running of the coaster 11 is provided at the front end of the substrate 10 of the coaster 11, and the front end of the sliders 9 and 9a of the coaster 11 is linear when the folding door FD is fully opened. When abutting against the front support piece 8 at the right end of the rails 7 and 7a, the rail is sandwiched between the base of the front support piece 8 joined on the base 6 and the clamp plate 23 arranged opposite to the base. doing.
Thereby, in particular, in the initial stage of the operation of closing (extending) the folding door FD from the fully open (bending) state of the folding door FD, the coaster 11 can be moved along the linear rails 7 and 7a while pressing the coaster 11 toward the inner surface D1 side. Thus, the closing force of the folding door FD is satisfactorily transmitted to the balustrade submerging device 5 so that the device 5 operates more smoothly.
The base 6 is covered with a base cover 6a so as to conceal most of the balustrade submerging apparatus 5, but is partially omitted in the figure for convenience.

Next, the operation of the handrail configured as described above will be described with reference to the drawings.
First, in the closed (extended) state of the folding door FD, the hand door Da and the fishing door Db are on the same line, and the output rod 14 holds the state where the coaster 11 is pressed to the left side via the connecting rod 15, and the slider 9 and 9a rear end contact | abuts to the rear support piece 8a of the linear rail 7 and 7a left end, and the coaster 11 is located in the base 6 left end.
At this time, the flange 16 has a lower trochanter located at the upper end of the long hole 18 of the coaster 11 and tilted to the right, holding the bent state with the linkage 17 and positioning the support rod 2 on the vertical line, The balustrade 1 is vertically elongated along the inner surface D1 (see FIGS. 1 to 3).

Then, when the fishing door Db is rotated in the opening direction to open the folding door FD by an automatic opening / closing device or the like, the tip of the output rod 14 is displaced according to the rotation position of the fishing door Db, and the output rod 14 Pulls the coaster 11 through the connecting rod 15 and moves the sliders 9 and 9a from the left end of the linear rails 7 and 7a to the right (hinge side end a1) side.
By the movement of the coaster 11 to the right side, the lower end of the hook 16 is also pulled to the right, and the hook 16 rotates counterclockwise around its pivot 16a, and the support rod 2 is centered around its pivot 2a via the linkage 17. Push up to rotate clockwise (see FIGS. 4-7).

Thereafter, when the folding door FD is fully opened (bent), the front ends of the sliders 9 and 9a come into contact with the front support piece 8 at the right end of the linear rails 7 and 7a, and the roller 22 intervenes between the base of the front support piece 8 and the clamp plate 23. Then the coaster 11 stops.
At this time, the rod 16 and the linkage 17 are extended, and the rod 16 is supported in contact with the stopper 20 at the upper left side and supported by the holder 21 at the upper front of the cage 16 via the linkage 17. The support rod 2 is firmly pushed up and supported to maintain the state that the balustrade 1 is tilted, that is, the state in which the balustrade 1 is slanted from the inside of the car through the entrance / exit G to the lower side of the car (see FIGS. 8 to 10).

As a result, the passenger walks along the handrail 3 with the lower end 1b of the balustrade 1 inclined downward from the entrance G as the starting end of the support, and can step on the step S at the entrance G and safely get on without any difficulty.
Also, since the rail 1 can be used as a handrail for getting off the vehicle, the passenger walks along the handrail 3 with the upper end 1a of the rail 1 from the inside of the vehicle as a support end, and is safe from the step S of the entrance G. You can get down to.

  When the folding door FD is closed from the fully opened state, the balustrade sunk device 5 operates in the reverse order to the interlocking operation of the folding door FD so that the folding door FD extends and the entrance / exit G is closed. 1 stands vertically vertically along the inner side surface D1 of the hand door Da, and the state is firmly held.
