Description

  The present invention relates to a movable home fence that is erected along a side edge of a platform such as a railway and that opens and closes when the vehicle gets on and off.

A movable home fence that opens and closes according to the timing of getting on and off the vehicle by forming a fence along the side edge of the platform in order to prevent falls from the platform to the track side and contact accidents between the vehicle and passengers entering the platform. Is known (see, for example, Patent Document 1).
The movable platform fence generally supports a sliding door type entrance / exit door by a door pocket fixed to the platform. Then, the passenger door is pushed out from the door pocket to close the passenger door (fully closed state), and is pulled back to the door bag to release the passenger door (fully opened state).

  The structure in which the passenger door is supported by the door pocket has a configuration in which a rail is provided on the passenger door and a guide roller for guiding the rail is provided in the door pocket. Since the rail and the guide roller engage with each other with a gradual dimensional relationship, when the passenger door is urged by belt driving or the like, the rail and the guide roller operate lightly without generating a large friction, thereby realizing quick opening and closing of the passenger door.

  However, since the rail and the guide roller are engaged with each other with a gradual dimensional relationship, rattling of the passenger door is inevitably caused. For example, in a case where the entrance / exit door closes the entrance / exit and receives external force due to the wind pressure of the passing train, the entrance / exit door may rattle in the surface direction of the door. Even if rattling occurs, there is no functional problem, but it is desirable to suppress rattling when an external force is applied to the fully closed entrance / exit door.

  In addition, for rattling in the vertical direction, in cases where passengers waiting for a train lean on the doorway, they receive a considerable load, which puts excessive force on the support structure and drive mechanism in the door pocket, causing failure. It becomes the cause of.

  The present invention has been made in view of such circumstances, and has a support structure that can suppress the rattling of the door even when an external force is applied to the fully closed passenger door while maintaining a quick opening and closing operation as in the prior art. The purpose is to realize a movable home fence.

  A first form for solving the above-described problem is a movable home fence including a sliding door type passenger door and a door pocket portion that opens and closes the passenger door, and the passenger door is a predetermined door-side door. The width portion is arranged and configured to be positioned in the door pocket when fully closed, the entrance door includes a convex portion at the predetermined width portion of the door surface, and the door pocket portion is the convex portion when the entrance door is fully closed. This is a movable home fence provided with a roller (for example, the side roller 252 in FIG. 4) that is in contact with or close to.

  According to the movable platform fence of the first form, when the passenger door is in the fully closed state and is supported by the door pocket, the convex portion abuts or approaches the roller in the door pocket. Therefore, even if an external force that pushes the door surface acts on the fully-closed entrance / exit door, rattling can be suppressed.

  In the second mode, the passenger door includes the convex portions at the predetermined width portions of the door surfaces on the platform side and the track side, and the door pocket portion includes the rollers at positions corresponding to the convex portions. It is a movable home fence of a 1st form.

  According to the 2nd form, while the effect similar to the movable home fence of a 1st form is acquired, since a convex part and a roller are arrange | positioned on both the front and back of a passenger door, rattle can be suppressed more effectively.

  In the third mode, the passenger door includes the convex portions at different positions in the door opening / closing direction and / or the vertical direction, and the door pocket portion includes the rollers at positions corresponding to the convex portions. It is the movable home fence of 1 or 2nd form.

  According to the 3rd form, while being able to acquire the same effect as the movable home fence of the 1st or 2nd form, it can control rattling more effectively by receiving the shake of a passenger door at a plurality of points, up, down, left, and right. . In addition, if the convex part is configured as an independent part, and the part is damaged or worn to the extent that it is necessary to replace the convex part, it can be restored with low repair costs and repair work by replacing the parts individually. be able to.

  A 4th form is a movable home fence in any one of the 1st-3rd form in which the said convex part has a slope part which inclines at least in the extrusion direction of the said passenger door.

  According to the fourth form, the same effect as the movable home fence of any one of the first to third forms is obtained, and when the passenger door is pushed out and closed, the roller is first engaged with the end of the convex part. Even when the entrance / exit door is swung in the door surface direction, the entrance / exit door can be smoothly guided to a predetermined position by the roller hitting the slope. Therefore, the opening / closing operation can be made smooth, and the occurrence of collision noise between the roller and the convex portion can be suppressed.

  In the fifth embodiment, the door pocket portion includes an upper roller portion and a lower roller portion that sandwich the entrance door from the upper surface side and the lower surface side, and an urging portion that urges the upper roller portion downward (for example, FIG. 4). The movable guide fence of any one of the first to fourth forms having the upper guide roller block 210, the swing type upper guide roller 218, the swing arm 220, and the spring 222).

  According to the 5th form, while having the same effect as the movable home fence in any one of the 1st-4th form, the upper roller urges the entrance door downward by the energizing part, and the entrance door is made Since it can be closely supported by the upper and lower roller parts, the cause of rattling can be more reliably removed. In addition, in a state where the entrance / exit is fully closed, that is, the entrance door is pushed out from the door pocket, an external force acts from above, such as a passenger waiting for a train leaning on the entrance / exit door, and the external force includes an impact component. However, since a part of the impact component can be absorbed by the urging portion, the support structure and the drive system can be prevented from being out of order or malfunctioning.

The convex part 114 is a plate-like member that is horizontally long in the door opening / closing direction and is formed of resin, for example, and includes slopes 114a at both ends in the longitudinal direction. The convex portion 114 is fixed to the predetermined position on the door panel 102 by bonding or screwing.

  Of course, the convex portion 114 may not be formed as such a separate member, but may be formed integrally with the door panel 102 by extruding a corresponding portion of the door panel 102 or increasing the thickness thereof. is there.

Next, the door pocket part 200 will be described.
FIG. 4 is an AA longitudinal sectional view (see FIG. 5) of the door pocket portion 200 as seen from the home side, and shows a state in which the exterior cover 201 is removed. FIG. 5 is a BB vertical cross-sectional view (see FIG. 4) of the door pocket portion 200.

  The door pocket portion 200 includes (1) a pedestal 202 for mounting on a home, (2) four struts 204 made of steel material having an L-shaped cross section and erected at the four corners of the pedestal 202, and (3) An upper guide roller block 210 attached to bridge the upper ends of the columns 204, (4) a lower guide roller block 230 attached to the upper surface of the pedestal 202, and (5) a belt drive block attached to the upper surface of the pedestal 202 240, (6) a side roller 252 provided on the side roller stay 250 passed between the platform-side left and right columns 204 and between the track-side left and right columns 204, and (7) the movable home rail 2 And a control device 290 having an electric circuit and an electronic component for controlling the operation.

  The full width of the door pocket 200 (the width in the door opening / closing direction) is set shorter than the lateral width of the passenger door 100. That is, when the doorway is fully closed, a predetermined width portion on the door bottom side of the passenger door 100 is located in the door pocket portion 200, and the doorcase portion 200 supports the predetermined width portion so that the entire passenger door 100 is supported. The

The upper guide roller block 210 is a guide roller that engages with the upper guide rail 106 of the passenger door 100, and a swinging upper guide roller 218 that engages the rail while urging the rail downward from above, and a fixed type And an upper guide roller 224.
Specifically, an opening 214 is provided at the center of the base 212 connected to the pillars at the four corners. A support piece extends downward at the door end side end of the opening 214, and the support piece holds a horizontal swing shaft 216 orthogonal to the door opening / closing direction.

  A swing arm 220 that rotatably supports the swing type upper guide roller 218 is pivotally supported on the horizontal swing shaft 216. The upper surface of the swing arm 220 is in contact with the lower end of a spring 222 fixed at one end to the base 212 and suspended in the vertical direction. Therefore, the swing arm 220 is urged downward by the spring 222. The

  In addition, a fixed upper guide roller 224 that is rotatably supported by a horizontal shaft is provided on the door bottom side of the opening 214.

  The lower guide roller block 230 supports two lower guide rollers 234 engaged with the lower guide rail 108 of the passenger door 100 on a roller stay 232 fixed to the pedestal 202 so as to be rotatable about a horizontal rotation shaft.

  The belt drive block 240 includes a drive pulley 242, a driven pulley 244, a tension pulley 246, and a motor 248 that applies a rotational force to the drive pulley 242.

The rotation shaft of the tension pulley 246 is urged in a predetermined direction by a spring 247, and applies appropriate tension to the cog belt 112 that is stretched.
The rotation of the motor 248 is controlled by the control device 290. As appropriate, a configuration incorporating a reduction gear or the like is preferable. A description of a power supply unit that supplies power to the motor 248 and the control device 290 is omitted, but it is assumed that it is appropriately prepared in the same manner as a known movable home fence.

  The side roller stays 250 connect the home-side columns 204 or the track-side columns 204 in the lateral direction (door opening / closing direction). In the present embodiment, a total of four are provided, two on the platform side and two on the track side.

Each of the side roller stays 250 is provided with two side rollers 252 each having a roller made of an elastic resin rotatably supported on a vertical rotation shaft.
The side roller 252a of the upper side roller stay 250 on the home side is provided at a position facing the side roller 252b of the upper side roller stay 250 on the track side. Similarly, the side roller 252c of the side roller stay 250 at the lower part on the home side is provided at a position facing the side roller 252d of the side roller stay 250 at the lower part of the track side.
The gap between the opposing side rollers 252 is set to be the same as or slightly wider than the thickness of the entrance / exit door 100 where the convex portion 114 is provided. When the side roller 252 is engaged by being elastically deformed, it may be set slightly narrower.

Next, the operation and engagement relationship of each part in the fully opened / fully closed state of the entrance / exit will be described.
FIG. 6 is a partial cross-sectional view as viewed from the platform side around the door pocket portion 200 of the movable platform fence 2 in a fully opened state, and corresponds to a cross-sectional view taken along line AA in the fully opened state. FIG. 7 is a (1) CC cross-sectional view, (2) D partial enlarged view, and (3) E partial enlarged view around the door pocket portion 200 of the movable home fence 2 in the fully opened state.

  As shown in these drawings, when the passenger door 100 is attached to the door pocket portion 200, the lower guide rail 108 of the passenger door 100 is engaged with and supported by the lower guide roller 234 of the door pocket portion 200, and the upper door The guide rail 106 engages with the swinging upper guide roller 218 and the fixed upper guide roller 224. Due to these engagement relations, the passenger door 100 is correctly guided in the door opening / closing direction at the time of pushing / drawing.

  And in the fully open state, the convex part 114 of the passenger door 100 exists outside the door pocket part 200 (not shown in FIGS. 6 and 7), and the door panel 102 is only inserted between the opposing side rollers 252. It is. At this time, a sufficient gap L5 is formed between the side roller 252 and the door panel 102 so that the side roller 252 does not come into contact when the passenger door 100 moves.

  FIG. 8 is a partial cross-sectional view of the periphery of the door pocket portion 200 of the movable platform fence 2 in the fully closed state when viewed from the platform side, and corresponds to an AA cross-sectional view in the fully closed state. FIG. 9 is a (1) FF cross-sectional view, (2) G partial enlarged view, and (3) H partial enlarged view around the door pocket portion 200 of the movable platform fence 2 in a fully closed state.

  When the passenger door 100 is fully closed, the control of the control device 290 controls the motor 248 to rotate clockwise when the drive pulley 242 is viewed from the home side. Closed.

  At this time, as shown in FIGS. 8 to 9, the predetermined width portion on the door bottom side of the passenger door 100 is located in the door pocket portion 200, and the left and right center position of the convex portion 114 is the rotational axis position of the side roller 252. The positional relationship almost matches. Between the facing side rollers 252, the door panel 102 and the two convex portions 114 are positioned, and the gap between the side rollers 252 and the convex portions 114 is slightly vacant (close state) or elastic resin. The amount of contact (contact state) is set to such an extent that the side roller 252 made in this way is slightly bent.

  Therefore, even when an external force is applied in the direction of pushing the door surface against the passenger door 100 in the fully closed state, the side roller 252 can suppress rattling. Nevertheless, in the process of opening and closing the door, the gap L5 is formed between the side roller 252 and the entrance door 100 as described above, so that no extra friction is generated on the side roller 252; The conventional smooth and quick opening / closing operation is maintained.

  Even if an external force that presses the door surface of the passenger door 100 acts during the opening / closing operation and the side roller 252 rides on the end of the convex portion 114, the convex portion 114 is provided with the slope 114a. As a result, it is possible to suppress backlash associated with riding on the end portion.

  Further, as shown in FIG. 10, when an external force is applied from above, such as when a passenger waiting for a train leans on the entrance / exit door 100 in the fully closed state, the door bottom side of the entrance / exit door 100 tries to lift, The swinging upper guide roller 218 and the upper guide rail 106 and the lower guide roller 234 and the lower guide rail 108 are in close contact with each other by the urging force of the movable upper guide roller 218, so that there is no backlash. Even if the external force exceeds the urging force of the swinging upper guide roller 218 and the entrance / exit door 100 is temporarily tilted, the upper guide rail 106 eventually comes into contact with the fixed upper guide roller 224 and the tilt is restricted. When the external force disappears, the passenger door 100 is automatically restored to the normal position by the urging force of the swing type upper guide roller 218.

  Even if the external force includes an impact component, the swinging upper guide roller 218 swings together with the swing arm 220 to absorb the impact component, so that the support structure and drive system malfunctions and failures due to the impact are suppressed. can do.

  Therefore, according to this embodiment, the rattling etc. by the external force which acts on the fully-closed entrance / exit door 100 can be suppressed, and a sense of security as a “durable and well-made movable home fence” can be given.

As mentioned above, although embodiment which applied this invention was described, the form of this invention is not limited to the said structure, Abbreviation of a structure or a change can be given suitably.
For example, the position and number of the convex portions 114 are not limited to the above embodiment, and can be arbitrarily changed. Further, for example, instead of individually providing the convex portions 114 corresponding to the side rollers 252 as in the above embodiment, the convex portions 114 arranged on the left and right in the same line shape are connected to the left and right convex portions 114. It can also be formed as a single belt-like convex portion. Furthermore, one plateau-shaped convex portion including four convex portions 114 may be formed on the home side surface and the track side surface.
In addition, the slope 114a of the convex portion 114 is not both ends in the longitudinal direction, but only the slope 114a that is inclined in the push-out direction of the passenger door 100 (only the slope 114a on the left side as viewed in FIG. 3 in the case of the movable home fence 2R for right installation). It is good.

  Further, the side roller 252 is elastically supported on the side roller stay 250, so that the rotation shaft of the side roller 252 can be elastically displaced in the door surface direction (home side to track side direction) of the passenger door 100. It can also be set as a simple structure.
