2. Description of the Related Art Recently, the present applicants have disclosed, for example, Patent No. 25
A stair climber as shown in Japanese Patent No. 20216 and Japanese Patent No. 2527520 has been devised. The stairlift is shown in FIG.
As shown in FIG. 7 and FIG. 18, a rail member 301 provided along the stairs, a roller chain rack 302, and a guide member 303 are provided.
The moving body 306 is supported by the rolling contact of 05. The moving body has an electric motor 307 that is rotated by power supply via a power supply means 304, and rotates the sprocket 309 by rotation of the motor, and the sprocket meshes with the chain rack 302 to rotate the sprocket 309. The moving body 306 can move along the stairs 310.

On the other hand, an elevator basket (carrier) 311 is detachably connected to the moving body 306 by connecting means 312. Two guide rollers 313 and 315 are attached to the end of the lifting basket 311 so as to protrude therefrom.
13 is in contact with the upper guide 303a of the guide member 303, and the other roller 315 is in contact with the lower guide 303b of the guide member.
It is supported in contact with.

Accordingly, the stair climbing machine connects the elevator basket 311 to the moving body 306 by the connecting means 312, and in this state, the person in the wheelchair moves into the elevator basket 311. When the moving body 306 is moved by the rotation of the electric motor 307, the elevating basket 311 is continuously pulled by the connecting means 312 and moves while being supported by the guide member 303. At this time, even when there is a landing or the like on the stairs 310 and the slope is not constant, by changing the interval between the upper guide 303a and the lower guide 303b, the elevator basket 311 is maintained in a horizontal state.

[0005]

In the above-described conventional stair climbing machine, guide rollers 313 and 315 are arranged so as to protrude in front of the basket 311 and one of the rollers 313 is moved upward by a moment caused by the weight of the basket. And the other roller 315 is in contact with the lower guide 303b, so that the guide member 303 and the elevator basket 311 need to be rigidly configured, and the guide member can be arranged only on one vertical plane. For example, it could not be applied to spiral stairs and stairs bent in the middle.

Further, when the above-mentioned stair climber is applied to, for example, a two-step stair with a connecting passage interposed therebetween such as an overpass, separate stair elevators are arranged for the two stairs, respectively. It is necessary to raise the wheelchair to the connecting passage with one stairlift, then lower the wheelchair, cross the connecting passage by itself, and lower it again with the other stairlift, which increases equipment costs and increases It becomes twice as necessary, and the burden on station staff etc. also increases.

Further, while the lifting basket 311 is held in a horizontal posture, the moving body 306 changes its posture by the inclination of the stairs. Therefore, the connecting means 312 allows the relative posture change such as a spherical bearing. You need to use
The connecting means has a complicated structure.

Therefore, the present invention can maintain the elevator basket in a horizontal state even when the inclination angle changes on a vertical plane such as a landing and a communication passage, and can also provide a plan view such as a connecting portion between the stairs and the communication passage. It is an object of the present invention to provide a stair climber that can move the elevator cage even when it is curved or bent at the same time.

However, the moving body 3 moves while maintaining the vertical posture (the horizontal posture of the lifting basket 15).

At this time, the guide members 7 and 8 are curved (D) on a vertical plane and turned in the horizontal direction in the same manner as the linear meshing members 5 and 6, but are guided by the weight of the moving body 3. The rollers 12, 12, 13, 13 advance on the upper surfaces of the guide members 7, 8 along the curve D. In the curve, the traveling speed of the driving sprockets 10 and 11 is
Guide rollers 12, 12, 13, 1 located outside the curve
3 is required to advance at a high speed. However, each guide member 7, 8 is supported by two guide rollers 12, 12, and 13, 13, respectively, and the upper and lower two guide members 7, 8 are supported. Owing to the sharing and supporting of the load, the large weight of each guide roller 12, 12, 13, 13
Sprockets 10, 1
On the basis of the rotational force of 2, the guide rollers 12, 13 precede the horizontal state F while swinging the arms 30, 31 from the inclined position S.

Thus, even when the track equipment curves on a vertical plane such as a landing and a connecting portion with a communication passage, no special power is required for moving the guide rollers 12 and 13 forward, and each roller can be moved by a moving body. The mobile body 3 automatically follows while supporting the weight, and proceeds stably while maintaining the predetermined posture of the moving body 3.

Next, a case (2c) in which the track equipment in a plan view is curved like a connecting portion between the steps U ₁ and U ₂ and the communication passage Ur will be described with reference to FIGS. 8 and 9. When the guide member 8 'is on a vertical plane, the two guide rollers 116,
When the guide members 7 and 8 are curved, the guide roller 116 is moved by the guide member 8.
It does not function as a steady rest.

For this purpose, a stabilizing device (stabilizing roller means) 3
6 are provided. A pair of front and rear guide rollers 4 sandwiching the guide member 8 by the curve of the guide member 8
8, 49 and 50, 51 follow the curve. Then, the gears 37 and 39 rotate by the same angle via the support members 45 and 46, the sliders 42 and 43, and the arms 40 and 41, and this state is at the center of the moving body 3 on the radius of curvature center line Z, that is, the drive. With the meshing position of the sprocket 11 and the linear meshing member 6 and the meshing surfaces of the gears 37 and 39 positioned, the supporting members 45 and 46 were forcibly rotated in the opposite directions by the same angle according to the curvature of the guide member 8. Will be. As a result, the pair of front and rear guide rollers 48, 49 and 50, 51 roll while sandwiching the curved guide member 8 and are positioned in a direction perpendicular to the curve center line, that is, in a position parallel to the curve tangent. The moving body 3 (front-back direction) is held.

Further, as shown in FIG. 5, the guide member curved portion (2c) located between the stairs and the communication passage has an inclined angle which is changed in the horizontal direction even on the vertical plane. Rollers 48, 49 and 50, 51
Will also move relatively up and down. For this reason, the supporting members 45 and 46 are arranged so that the pair of front and rear guide rollers follow the guide member 8 that changes in the vertical plane direction.
Is moved by the ball sliders 42 and 43 in the vertical direction, and the front and rear guide rollers 48, 49 and 50 and 51 are moved by the guide member 8 regardless of the change in the vertical direction of the guide member.
Follow.

Further, the guide rollers 48 which are nipped from both right and left sides by the change of the guide member 8 in the vertical plane direction,
The support members 45, 46 are respectively connected to the sleeve members 45b, 46b via bearings via the bearings 45, 46b.
Since the supporting member 59 is supported, the guide roller always rolls on the left and right sides in accordance with the change in the inclination angle of the guide member 8 accurately.

Further, the front and rear arms 58, 59 are rotatably supported by plates 62, 63 having rotating shafts 60, 61 on a vertical line of the guide member 8, and the guide rollers 48, 49 and 50 are respectively supported by the plates. , 51 are supported, so that the front and rear plates 62, 63 are respectively orthogonal to the guide member 8 at the front and rear positions, that is, the extension line Z ₁ connecting the center lines of the guide rollers 48, 49 and 50, 51. , Z ₂ is automatically adjusted so that toward the curve center. Thereby, each guide roller 48, 49 and 50, 5
1 is aligned with the guide member 8 having a circular cross section, so that the right and left side surfaces are accurately pinched even though the guide member is curved in a plan view.

Accordingly, even if the inclination angle of the guide member 8 changes in the vertical plane direction, the guide rollers 48, 49 and 50, 51 in front of and behind the stabilizer 36 accurately align with the guide member 8 from the left and right directions. The pinching and following movements are forcibly held against the support devices 45 and 46 of the front and rear guide rollers so as to be always parallel to the curve of the guide member corresponding to the curvature of the guide member 8 and moved. The swing of the body 3, and hence the basket 15 in the curved portion in plan view, is prevented.

On the other hand, in the curved portion (2c) in plan view, as shown in FIG.
The rotation plane of (same for 10) does not coincide with the longitudinal direction of the linear meshing member 6 (same for 7) that is vertically below the guide member 8. Therefore, as shown in FIG. 10 (d), the diameter of the roller 19 is smaller and longer than that of the roller 18 of the roller chain 20.
Are arranged radially along the curve. In this state, a plurality of drive sprockets 11 (10)
Although the individual teeth mesh with the roller 19, even if the roller 19 is inclined with respect to the tooth surface of the sprocket, the meshing proceeds smoothly without interfering from the start of meshing and the moving body 3 follows the curve. Can proceed. In the above-described embodiment, the pin 17 and the roller 19 implanted in the case member 32 are used for the linear meshing members 5 and 6 without using the roller chain 20 in the curved portion in a plan view. A flexible roller chain that can be deformed at a predetermined curvature also in the longitudinal direction of the pin by connecting the link plate and the pin with a long hole or the like may be used.

The moving body 3 integrally attached with the lifting basket 15 rises along one of the steps U ₁ while receiving the supply of electricity from the power supply device 35 formed of a trolley wire, and further curves in a plan view. reaches the communication passage Ur, move horizontally along the communication passage, and descends along the other stairs U ₂ curved again, reaches under the stairs. In this state,
The transfer board 123 of the elevator basket 15 is dropped, and the person in the electric wheelchair is dropped from the elevator basket 15.

At this time, in the curve portion 2c in plan view,
The rotation of the electric motor 9 is controlled so as to be slow, so that a large centrifugal force or the like does not act on the lifting basket 15 located outside the rotation of the moving body. The power supply device 35 includes a cover 1
Although the structure is such that it is difficult for the hand to enter through the slit 117a of the 17th, the slit portion may be closed with a rubber plate with a cut or the cover may be made into a labyrinth structure to prevent the hand from entering.

Also, in the event of an abnormal situation, for example, when the supply of electricity is cut off, the power supply to the electromagnetic brake 22 is also cut off and the brake is actuated immediately, stopping the lower drive sprocket 11 and stopping the moving body 3. Stop on the spot. When the moving speed of the moving body is out of the predetermined range due to an abnormality of the control unit or the like, the pulse length is detected and the electromagnetic brake 22 operates to stop the moving body. Also, when the synchronous chain 21 is cut, the cut is detected and the electromagnetic brake 21 is operated.
Further, the roller chain 2 constituting the linear meshing members 5 and 6
0 is very unlikely to be cut, but even if cut, the roller chain 20 does not fall because the roller chain 20 is held in the holding plate 32c.
The meshing relationship with 0, 11 is maintained, and in this state, the electromagnetic brake 21 operates to stop the moving body.

Guide rollers 48, 49 and 50, 5 are provided on these arms 58, 59 so as to sandwich the rail 65 in the lateral direction, respectively.
1 is rotatably supported.

In the present embodiment, the guide rollers 48, 49 and 50, 5
1 is not supported rotatably about the vertical axis. Therefore, when the rail 65 is curved, the arm is not always directed in the radius of curvature direction. Therefore, as shown in FIG. 16 (a), a slight gap exists between the rollers 48, 49 and the rail 65. Need to exist. Therefore, the guide rollers 48, 49 and 50, 51 have flanges 48a, 49a, respectively, and are configured to sandwich the rail 65 in the vertical direction by these flanges.

Next, the operation of the stair climber according to the second embodiment will be described. As in the first embodiment, the lifting basket is integrally connected to the moving body 3, and a disabled person or the like in an electric wheelchair is placed on the lifting basket.

[0074] In this state, when rotating the electric motor 9 by pushing the start switch, rotating on the drive sprocket 10 ₂ directly from the output shaft 9a of the motor 9 is transmitted further bevel gear 131, 134, synchronous sprockets 109,
Chain 21, sprocket 110, bevel gear 145
And it is transmitted to the lower drive sprocket 11 ₂ through 147. These two drive sprockets 10 _2, 11 ₂ are respectively meshed from each laterally flexible roller chain 20 ₂ constituting the upper and lower linear engagement member 5 _2, 6 _2, and both the drive sprocket 10 _2, 11 ₂ is the speed in by rotating, moving body 3, while maintaining the posture to hold the lift cage in a horizontal state, moves while being guided by the guide member 7 _2, 8 _2. At this time, the weight acting on the movable body 3 from the lifting basket or the like is carried by the upper and lower guide member 7 _2, 8 ₂ via a guide roller 12 _2, 13 _2.

The moving body 3 can be used even when the inclination angle changes on a vertical plane at the connecting portion between the track facility 2 and the landing and the stairs and the communication path, even if the above-mentioned vertical driving sprocket 10 is used.
_The vertical posture is maintained by the same speed drive of ₂ and 112,
At this time, the upper and lower flexible roller chains 20 ₂ (5
_2, 6 _2), since the inclination angle of the longitudinal direction (facility direction) is changed, relatively changes the moving body and the angle of the upper and lower flexible chain.

[0076] the upper drive sprocket 10 ₂ and the support frame 135 supporting integrally the electric motor 9, the horizontal support shaft 1
33 is swingably supported on the frame 3a around the (cylindrical portion 132), and since it is guided by the guide member 7 _2, 7 ₂ 'by rollers 140,141,141, the moving body 3, flexible even relatively angular change with respect to the longitudinal direction of the chain, the rotation plane of the upper drive sprocket 10 ₂ automatically swing to match the longitudinal direction of the roller chain 20 _2. Furthermore, the electric motor 9 is also pivoted integrally, rotation of the output shaft 9a of the motor 9, not via a universal joint or the like, is transmitted onto the drive sprocket 10 ₂ always directly.

[0077] Similarly, automatically pivot support frame 146 which holds the lower drive sprocket 11 ₂ and the emergency brake 22, the lower drive sprocket 11 ₂ of the rotary plane coincides with the longitudinal direction of the lower roller chain The rotation of the driving sprocket is always transmitted integrally to the emergency brake 22. Further, always the rotation of the lower drive sprocket 11 ₂ is transmitted to the emergency brake 22 together, the emergency brake is always accurately detect the pulse length, reliably actuating the emergency brake in abnormal.

At this time, the guide members 7 ₂ , 7 ₂ ′, 8 ₂ ,
Rollers 140, 141, 150 guided to 8 ₂ '
Since only the weight of the support frames 135 and 146 supporting the electric motor 9 or the emergency brake 22 and the like acts, the support frame easily swings following the change in the angle of the guide member, and the vertical drive sprocket 10 _2, 11 precisely mesh with ₂ always from the side in the vertical flexible roller chain 20 ₂ at the same angle. By accurately meshing the driving sprocket with the flexible chain and directly driving the driving sprocket from the electric motor 9, the moving body 3 can be moved accurately and reliably with high transmission efficiency.

Further, the track equipment is curved in plan view (2
In c), a stabilizer 36 similar to the previous embodiment is used.
_The function ₂ prevents the moving body 3 from swinging about the vertical axis.
At this time, the rollers 48, 49 and 5
Although there is a slight gap between the rails 0 and 51, since each roller has a flange, each roller can be moved up and down according to an angle change in a vertical plane of the rail, and the roller that holds the rail can be moved. Since either one of the rolling members always rolls in close contact with the rail 65, it is possible to prevent the moving body 3 from swinging.

[0080] Note that the embodiments of the second uses a flexible roller chain 20 ₂ as a linear engagement member 5 _2, 6 ₂ of the upper and lower, relatively gentle curve (small curvature)
The change in track equipment in the vertical plane is handled by the bending of the flexible chain based on the play between the pin and the bush, and the change in track equipment in a planar view that results in a relatively tight curve (large curvature) is calculated by the relative rotation between the pin and the bush. Therefore, it is sufficient to provide a series of flexible chains over the entire length of the facility such as an overpass, and it is possible to easily cope with not only the overpass but also other facilities such as a spiral staircase.

In each of the first and second embodiments, not only the above-mentioned overpass but also stairs and communication passages by underground passages, stairs bent at a right angle or the like on the way, or ordinary straight stairs, etc. Of course, it can be applied to The first and second embodiments described above, the upper and lower linear engagement member 5,5 ₂ 6,6 ₂ respectively guide members 7 ₂ corresponds to 8,8 ₂ was facilities, Only one guide member for supporting the weight of the moving body 3 is sufficient. Further, although the elevating basket is detachably attached to the moving body, a foldable elevating basket may be integrally fixed to the moving body.

[0082]

According to the first aspect of the present invention, since the upper and lower rotating mesh members respectively mesh with the linear mesh members and travel on the moving body at the same speed, the overpass having a landing and a communication passage is provided. Even on stairs such as the stairs, the elevator basket can always be held horizontally and transported stably, and the weight acting on the moving body from the elevator basket etc. is supported by guide members via guide rollers. As a result, an excessive load due to a moment or the like does not act on the guide roller and the guide member, etc., and a series of track means, a single moving body, and a lifting basket can cope with the problem and improve reliability. it can.

According to the second aspect of the present invention, the linear meshing member is disposed such that the longitudinal direction of the rotary support member and the roller is substantially horizontal, so that the rotary meshing member is formed of the linear meshing member. The linear meshing member can be prevented from being directly exposed to the step side by meshing with the vertical plane, and the rotating plane of the rotating meshing member can be aligned with the longitudinal direction of the linear meshing member, thereby ensuring reliable and accurate meshing. In addition to being able to hold the moving body, the moving body can be made compact in the width direction (the length of protrusion from the wall surface).

According to the third aspect of the present invention, the roller chain is provided in a direction in which the roller chain is bent in the vertical direction so as to cope with a change in the inclination angle in the vertical plane and to have a predetermined curvature in plan view. The linear meshing member which is not directly exposed on the side of the stairs can be provided with low cost and high reliability by arranging. According to the fourth aspect of the present invention, since the linear meshing member is disposed such that the longitudinal direction of the rotation supporting member and the roller is substantially vertical, the facility of the track means is facilitated and various stair facilities are provided. Can be easily handled.

According to the fifth aspect of the present invention, by bending the flexible roller chain in the vertical direction,
A relatively steep curve (large curve) that responds to a change in the inclination angle in a vertical plane such as a landing with a relatively gentle curve (small curvature) and that is bent by the relative rotation of the pins and bushes of the flexible roller chain. Inexpensive and highly reliable installation of track means using flexible roller chains that are continuous over the entire length of an overpass, etc., in response to changes in the plan view of the connecting portion between the stairs and the communication passage, etc. And various stairs such as spiral stairs can be easily handled.

According to the sixth aspect of the present invention, the rotational plane of the rotary meshing member always coincides with the longitudinal direction (facility direction) of the linear meshing member such as a flexible roller chain.
Regardless of the relative angle change between the moving body and the linear meshing member,
In addition to always maintaining a proper and reliable meshing relationship, the electric motor is also fixed so as to swing integrally with one of the rotary meshing members, so that rotation is always transmitted directly from the electric motor to the rotary meshing member. Thus, the moving body can be reliably driven with high transmission efficiency.

According to the present invention, when an abnormality occurs,
The emergency brake is activated, and the moving body can be reliably stopped, and safety can be improved.
