Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bus wheelchair getting-on / off device for reducing the burden on an operator when pulling out and setting a slope member stored under the floor of a step.

[0002]

2. Description of the Related Art Conventionally, in order to improve the ease of getting on and off a bus for wheelchair users, a slope member is stored at a lower portion of a step of a bus entrance, so that it is possible to normally get on and off using a step. When a wheelchair user gets on and off, pull out the stored slope member and bridge the floor inside the vehicle and the sidewalk with the slope member so as to eliminate the step between the sidewalk and the floor inside the vehicle. A wheelchair getting on / off device is proposed in Utility Model Registration Publication No. 2582601.

[0003]

In the case of an ordinary, multi-step bus such as a so-called two-step bus, there is a large step between the floor surface in the vehicle and the sidewalk. In the case of bridging, a slope member having a relatively long overall length must be used in order to secure a gentle slope, and the weight increases due to the need to guarantee strength.

Further, in order to bridge the sidewalk and the floor inside the vehicle without interfering with each step, it is necessary to secure the height by supporting the slope member drawn out of the storage portion by lifting it with the support lever. There is.

As a result, when an operator such as a crew member sets the slope member, the worker first pulls out the slope member,
Next, a relatively heavy slope member must be lifted using the support lever as a fulcrum, which causes a problem that a great burden is imposed on an operator.

Similarly, when the support lever is tilted to store the slope member, the slope member is heavily extended to the support lever, so that the operator slowly tilts the support lever while holding the slope member. Must be carried out, which imposes a great burden on workers.

Further, in Japanese Utility Model Registration No. 2582601, since the slope member is retractably stored in the storage portion, when the vehicle travels in a state where the slope member is stored, vibration caused by running of the vehicle occurs. As a result, the slope member rattles, and the rattling sound caused by the rattle is transmitted to the passengers as noise, giving the passenger discomfort.

To cope with this, for example, Japanese Patent Laid-Open No. 10-2
In the state where the throw member is stored in the storage section, the rear end of the slope member is pressed against the rear end of the storage section via the elastic member, and the front end of the slope member is stored in the storage section. There is disclosed a technique for suppressing the backlash of the slope member by pressing with an elastic member provided on the inner surface of a lid that opens and closes.

However, this prior art requires an elastic member and a bracket for receiving the elastic member in order to suppress rattling of the slope plate, which not only complicates the structure but also increases the manufacturing cost. In addition, since the elastic member is rattled due to deterioration, it is necessary to periodically replace the elastic member, and the maintenance is complicated.

The slope member disclosed in Japanese Patent Laid-Open Publication No. Hei 10-230791 discloses a technique in which a handle is provided at a substantially central portion of a front portion, and the handle is gripped to put the slope member in and out of the storage portion. ing.

However, when pulling out the slope member, if the user lifts the slope member by gripping the handle, the load is concentrated on one point of the handle, so that the posture of the slope member is not stable and the operability is poor.

SUMMARY OF THE INVENTION In view of the above circumstances, a first object of the present invention is to provide a bus wheelchair getting on / off device capable of reducing a burden on an operator and smoothly setting and storing a slope member.

A second object of the present invention is to provide a simple structure, which does not require replacement of parts, allows the slope member to be taken in and out of the storage portion in a stable posture, and securely fixes the slope member to the storage portion. The present invention provides a bus wheelchair getting on and off device that can be operated.

[0014]

According to a first aspect of the present invention, there is provided a slope member which is retractably stored in a storage portion formed under a floor of a step, and which is provided when the slope member is pulled out. In a wheelchair getting on / off device for a bus that bridges a sidewalk and a floor inside a vehicle in a state where a member is raised via a support lever and the middle of the slope member is supported by the support lever, the support lever is attached to the support lever. A biasing means for biasing in a direction in which is raised.

In such a configuration, when the slope member stored under the floor of the step is pulled out and the support lever is raised, the support lever is biased in the rising direction by the biasing means. When the user pulls out and sets the slope member, the force in the direction of raising the support lever is reduced.

According to a second aspect of the present invention, there is provided a slope member which is stored in a state where it can be pulled out and pivotally attached to a storage portion formed under the floor of the step, and by pulling out the slope member, the sidewalk and the floor surface in the vehicle are pulled out. In a wheelchair getting on / off device for a bus, a fixing means extending in the width direction of the slope member and capable of moving up and down with respect to the slope member is pivotally attached to a front portion of the slope member, At least one pair of engagement portions extending downward from the center to the left-right symmetric position is provided, and the engagement portion is located at a position facing the engagement portion when the slope member is stored in the storage portion in the storage portion. It is characterized in that a hook portion for hooking is provided.

In such a configuration, when pulling out the slope member from the storage portion, the fixing means which is pivotally attached to the front part of the slope member is gripped, and the engaging portion provided on the fixing means is engaged. And pulling out the slope member by pulling out this fixing means. When storing the slope member, push the slope member in the direction of the storage portion while holding the fixing means, and after confirming that the slope member is stored in the storage portion in a predetermined manner, extend the slope member downward. The engaged engaging portion is engaged with the engaging portion, and the slope member is positioned and fixed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 to 5 show a first embodiment of the present invention. FIG. 1 shows a side view of the two-step bus.

On the left side of the two-step bus, a middle entrance a, front entrance b, and rear entrance c are provided, and an upper step 2a is provided between the floor 2 in the vehicle and the middle entrance a. A lower step 2b is provided. A storage section 4 for storing the slope member 3 of the wheelchair access device 1 is formed below the floor of the upper step 2a. In the following description, the pull-out direction of the slope member 3 is described as “front”, and the storage direction is described as “rear”.

As shown in FIG. 3, the slope member 3 includes a slope plate 3a, a sub-slope plate 3b slidably held in a forward direction with respect to the slope plate 3a,
And a connecting plate 3c which is connected to the rear end of the slope plate 3a so as to be able to open freely. Normally, the connecting plate 3c is folded on the slope plate 3a and the sub-slope plate 3b
Is stored on the lower surface of the slope plate 3a, and is stored in the storage unit 4 in this state.

The rear end of the slope plate 3a is connected to the slider 6 via the support lever 5. The slider 6 moves the slope member 3 along guide rails (not shown) formed on both sides of the storage unit 4 when the slope member 3 stored in the storage unit 4 is taken in and out. A pair of opposed members is provided on both sides of the slope plate 3a.

The tip of the slider 6 is positioned at the opening 4a of the storage section 4.
When it is projected from the opening 4a by a predetermined amount, it is hooked on a stopper (not shown) to restrict the projection from the opening 4a, and the projected state is maintained. Reference numeral 4b denotes a lid for opening and closing the opening 4a.

A pair of support levers 5 are provided on both sides of the slope plate 3a. As shown in FIG. 5, one end of each support lever 5 has a hinge 7 which rotates integrally with the support lever 5. The other end of the support lever 5 is pivotally supported at a pivot point P1 of a bracket 3d formed at the rear end of the slope plate 3a.

A lever 8 is fixedly mounted on the hinge 7. At the end of the lever 8, a hook point for hooking one end of a tension spring 9 on a line connecting the pivot points at both ends of the support lever 5. P2 is formed, and the other end of the tension spring 9 is hooked to a hook point P3 of a bracket 3d formed on the slope plate 3a.

As shown in FIG. 5, when the slope member 3 is stored in the storage section 4, the support lever 5 is set to maintain a horizontal state. In this state, the tension spring of the bracket 3d is set. The hook point P3 for hooking 9 is
It is set at a position distant from the pivot point P1 that pivotally supports the other end of the support lever 5 with respect to the hinge 7 and at a position offset downward.

The support lever 5 always receives the urging force of the tension spring 9, and when the support lever 5 is in a horizontal state,
That is, when the slope member 3 is stored in the storage unit 4, the locking point P for locking both ends of the extension spring 9 is provided.
2 and P3 are pulled at a distance L, and at this time, the tension spring 9 urges the support lever 5 in the counterclockwise direction in FIG.

When the slope member 3 connected to the support lever 5 is lifted upward while maintaining a substantially horizontal state, the support lever 5 rotates about the hinge 7 and the hinge 7 Until the hook point P3 for hooking the tension spring 9 reaches the horizontal axis HL passing through the center of rotation of, the hook point P2 and P3 maintain a substantially constant distance L, and the hook point P3 is When passing through HL, the distance between the hook points P2 and P3 gradually decreases.

The slider 6 is provided with a stopper 6a for regulating the opening angle of the support lever 5 at the time of rising, and the support lever 5 is fixed to a preset maximum opening angle by the stopper 6a. The maximum opening angle is
In the present embodiment, it is set to 116 °.

Further, the tension spring 9 is set so as to be shortened to a range of an opening angle larger than the position where the support lever 5 is hooked on the stopper 6a, so that the support lever 5 is hooked on the stopper 6a. And the hanging point P at that time
Even when the distance between P2 and P3 reaches L '(L>L'), the urging force on the support lever 5 is retained.

In the two-step bus, the step from the lower step 2b to the floor 2 in the vehicle is larger than that of the one-step bus or the non-step bus, and as shown in FIG.
In order to bridge the floor surface 2 and the sidewalk 10 on a gentle slope, it is necessary to use the slope member 3 having a relatively long length. In consideration of storage efficiency, the slope member 3 is divided into three parts. I have. In addition, the slope member 3 is connected to each step 2
Since it is necessary to bridge the floor surface 2 and the sidewalk 10 without interfering with the a and 2b, the slope member 3 is supported in a state where it is lifted by the support lever 5 in the middle.

Next, the operation of the present embodiment having the above configuration will be described. Slope member 3 of wheelchair getting on / off device 1
Is normally stored in a storage unit 4 provided under the floor at the upper step 2a of the middle entrance a, and the opening 4a is
As shown in (a), it is closed by the lid 4b.

When the wheelchair getting on / off device 1 is used, first, as shown in FIG. 4 (b), the crew (the driver in the case of a one-man bus) opens the lid 4b downward, and then stores it in a superposed state. When the slope member 3 is gripped and pulled out by a grip portion (not shown), a slider 6 supporting a rear portion thereof moves together with the slope member 3 along a guide rail (not shown).

The slope member 3 is configured such that the slider 6 is
Is pulled out to a position where it is engaged with a stopper (not shown). At this position, when the slope member 3 superimposed in a three-layer state is further pulled, the slider 6 is connected to the slider 6 via the hinge 7. The lever 8 supported and rotated upward.

At this time, the engaging point P2 of the tension spring 9
However, until the horizontal axis HL is reached, the pivot point P2, which locks both ends of the extension spring 9, rotates while maintaining a substantially constant distance L, and the latch point P3 passes through the horizontal line HL. Then, the distance between the hook points P2 and P3 gradually decreases.

The urging force of the tension spring 9 in the direction in which the distance between the hooking points P2 and P3 becomes shorter assists the upward rotation of the support lever 5, so that the crew member trying to pull out the slope member 3 can use it. The burden is reduced.

When the support lever 5 is engaged with the stopper 6a formed on the slider 6, the tension spring 9
The distance between the latching points P2 and P3 for latching both ends of L becomes L ', and even in this state, the tension spring 9 is further contracted, that is, the support lever 5 is rotated clockwise in FIG. Since the force to be applied is acting, the support lever 5 is kept in a state of being stopped by the stopper 6 a by the urging force of the tension spring 9.

Next, the crew pulls out the sub-slope plate 3b forward from the slope plate 3a, puts the front end of the sub-slope plate 3b on the sidewalk 10, and sets the sub-slope plate 3c.
Is opened in the direction of the floor surface 2 in the vehicle around the rear end of the slope plate 3a, and the front end of the joint plate c is hooked on the floor surface 2.

As a result, as shown in FIG. 3, the sidewalk 10 and the floor surface 2 in the vehicle are connected via the slope member 3 on a gentle slope without any level difference, and it is possible to get on and off by a wheelchair.

When the passenger gets on and off the wheelchair, the sub-slope plate 3b and the joint plate 3c are vertically overlapped with the slope plate 3a interposed therebetween, and then the support lever 5 is moved downward, that is, counterclockwise in FIG. In the storage direction.

At this time, since the biasing force in the opposite direction is applied to the support lever 5 by the tension spring 9, even if the load of the slope member 3 is applied to the support lever 5, the support lever 5 is suddenly tilted. The burden on the crew at the time of storage is reduced.

As described above, according to the present embodiment, the support lever 5 is urged in the opening direction by the tension spring 9, so that the load on the crew member when pulling out and storing the slope member 3 is reduced. As a result, the slope member 3 can be set and stored smoothly.

FIGS. 6 to 12 show a second embodiment of the present invention. Note that the same components as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted. FIG. 7 shows a front view of a state in which the slope member 3 is stored in the storage unit 4 (however, the connecting plate 3c is omitted).

The slope plate 3a and the sub-slope plate 3b are
Both are formed of a relatively light metal plate material such as an aluminum alloy. Both side portions of the slope plate 3a are mounted on a pair of base frames 21, and are fixed via rivets or the like. A side frame 21a is bent upward at a substantially right angle at an outer end of each base frame 21, and a flange portion 21b is bent outward at a substantially right angle from an upper end thereof.

A sub-frame 22 is disposed below the base frame 21 in parallel. A sub-side frame 22a is formed at an outer end of each sub-frame 22 so as to be bent substantially at right angles upward. This sub side frame 2
2a is opposed to the outer surface of the side frame 21a bent at the base frame 21 at a predetermined interval, and the upper end thereof is fixed to the flange portion 21b bent at the base frame 21 by welding or the like. Has been established.

The slide base 23 is formed in a groove shape and has an opening surface mounted on the sub-frame 22. On the upper surface of the slide base 23, flange portions 3e formed on both sides of the sub-slope plate 3b are placed and fixed via rivets or the like. Further, the gap between the opposing surfaces of the slide base 23 is fixedly provided at predetermined intervals from the near side to the far side of FIG.

On the other hand, a lower portion of the guide plate 25 is fixed to the outer surface of the slide base 23 via a rivet or the like.
The upper part of the guide plate 25 is
It is inserted between 1a and 22a and slidably supported.

Posts 26 are vertically provided at symmetrical positions on the front bottom surface of each sub-frame 22, and one end of a support bracket 27 is fixed to the front surface of each post 26 by welding or the like. . Each of the support brackets 27 extends in a direction facing each other, and an end surface thereof is bent in an L shape to form a facing surface 27a.

An elongated hole 27b extending in the vertical direction is formed in the facing surface 27a. Both ends of a grip bar 28 which is an example of a fixing means extending in the width direction of the slope member 3 are formed in the elongated hole 27b. It is inserted so that it can move up and down. An engaging pin 28 which is an example of an engaging portion is provided at both ends of the grip bar 28.
a is provided. The engagement pin 28a extends downward, and is inserted into a guide hole 27c formed in a base plate 27d fixed to the bottom surface of the support bracket 27 by welding or the like.

Further, a stepped portion 4d for avoiding interference with the post 26, the support bracket 27, and the grip bar 28 is formed at the front of the floor surface 4c of the storage portion 4. In the state where the slope member 3 is stored in the storage part 4, as shown in FIG. 7, the engagement pin 28a is inserted into a locking hole 4e as a locking part formed in the step part 4d of the floor surface 4c.
