Description

  The present invention relates to a movable platform fence installed on a platform of a railway station.

  The movable platform fence is a kind of automatic door device installed on the platform of a railway station. Generally, the movable platform fence is configured by attaching a door body to a door pocket fixed to the platform so as to be able to advance and retract. When the train arrives at the platform where the movable platform fence is installed, the door of the movable platform fence is drawn into the door pocket. As a result, the entrance / exit is opened and passengers can get on and off the train. When the passengers get on and off, the door body is pulled out of the door pocket. As a result, the entrance / exit is closed, and then the train departs. And the entrance / exit closed state is maintained until the next train arrives.

  Such a sliding door type movable home fence needs to be configured to move forward and backward while keeping the door body in an upright posture. In particular, it is necessary to configure the door body so as not to fall in the front-rear direction, that is, the home side or the track side. When the door body falls in the front-rear direction, the door body interferes with the door pocket, and the operation of the door body is hindered. Further, when the door body swings in the front-rear direction, abnormal noise may occur. For this reason, conventionally, the movable home fence has been provided with a member that functions as an anti-tilt (rest) that restrains the door body from falling forward or backward. Hereinafter, a configuration example of the movable home fence according to the related art will be described with reference to Patent Document 1.

  The movable home fence (movable home fence) described in Patent Document 1 includes a door pocket fixed to the platform and a slide door (door body) slidably attached to the door pocket. The upper and lower sides of the slide door are formed with horizontally long grooves that extend in the width direction of the slide door (the direction in which the slide door advances and retreats). The upper horizontally elongated groove has a guide rail, and the lower horizontally elongated groove has a slide rail. Are installed. A slide block is mounted at a position corresponding to the slide rail of the door pocket. The slide block is slidably engaged with the slide rail. A guide roller is attached to a position of the door pocket corresponding to the guide rail. The guide roller rolls in contact with the guide rail. As described above, the slide door is configured such that the slide rail and the guide rail are respectively attached to the lower lateral groove and the upper lateral groove, and the slide door advances and retreats with respect to the door pocket. Therefore, the door body advances and retreats with respect to the door pocket while maintaining an upright posture.

JP 2010-126144 A

  In the movable home fence described in Patent Document 1, a horizontally long groove is formed in a main body of a door body (slide door), that is, a structural member (strength member) constituting the door body (slide door). For this reason, the cross-sectional area of the structural member (strength member) decreases at the site where the horizontally long groove is formed. Moreover, the laterally elongated groove extends over the entire width of the structural member (strength member). Therefore, there exists a problem that the intensity | strength of a door body falls. In addition, when the strength is reduced by providing the horizontally long groove, it is necessary to increase the thickness of the door body in order to secure the required strength. Or it is necessary to reinforce a door by another means. As a result, there is a problem that the mass of the door body increases, the power required to drive the door body increases, and the power consumption increases.

  The present invention has been made based on such a background, and an object of the present invention is to provide a movable home fence having a function of preventing the door body from falling down and suppressing power consumption.

  In order to achieve the above object, a movable home fence according to the present invention includes a door pocket, a door body attached to the door pocket so as to freely advance and retract, and the door body interposed between the door pocket and the door body. A support means that supports the door body in a freely movable manner, a slide rail that is fixed to the door body and that is spaced apart from the support means in the vertical direction and extends in the forward and backward direction of the door body, and a base portion that is the door pocket And an anti-falling fitting whose tip is slidably supported by the slide rail. The door body includes a frame and a sash frame that is fixed to the frame and holds a transparent plate, and the sash frame constitutes at least a part of the slide rail.

  According to the present invention, at least a part of the slide rail is formed on the sash frame. For this reason, compared with the case where the whole slide rail is formed in the frame of a door body, the fall of a door body can be prevented, without reducing the intensity | strength of a door body. Therefore, the door body can be configured to be lightweight, and the power consumption of the movable home fence can be suppressed.

  Hereinafter, embodiments of a movable home fence according to the present invention will be described in detail with reference to the drawings. In the drawings, the same or equivalent parts are denoted by the same reference numerals.

(First embodiment)
FIG. 1 is an explanatory diagram illustrating the configuration of the movable home fence 1 according to the first embodiment of the present invention. Fig.1 (a) is an external view which shows the external shape of the movable home fence 1 in a closed state, FIG.1 (b) is a block diagram which shows the state inside the door pocket of the movable home fence 1 in a closed state. In addition, FIG. 1C is a configuration diagram illustrating an internal state of the door pocket of the movable home fence 1 in an open state.

  As shown in FIG. 1A, the movable platform fence 1 includes a door pocket 3 fixed to the floor surface 2 of the platform of the railway station, and a door body 4 attached to the door pocket 3 so as to freely advance and retract. The door body 4 moves in the direction indicated by the arrow FWD in FIG. Moreover, it moves in the direction shown by the arrow BWD and is pulled back to the door pocket 3. FIG. 1A shows a closed state in which the door body 4 moves in the direction of the arrow FWD and is completely pulled out from the door pocket 3.

  First, a mechanism for supporting the door body 4 so as to freely move forward and backward will be described. As shown in FIGS. 1B and 1C, a guide rail 5 is disposed below the door body 4. The guide rail 5 extends parallel to the forward / backward direction of the door body 4 (the direction indicated by the arrow FWD or the arrow BWD in FIG. 1A) and is fixed to the door pocket 3. Further, a guide block 6 is fixed to an end portion of the door body 4 on the door bottom side (the end portion inside the door pocket 3 in FIG. 1B). Two guide rollers 7 are pivotally supported on the guide block 6. The guide rollers 7 are arranged at intervals in the forward / backward direction of the door body 4, and a part thereof is exposed below the guide block 6. Then, when the door body 4 advances and retreats with respect to the door pocket 3, the guide roller 7 comes into contact with the guide rail 5 and rolls. Thus, the door body 4 is supported by the guide rail 5 via the guide roller 7. The guide roller 7 includes two flanges (not shown), and the guide rail 5 is sandwiched between the two flanges. Therefore, the guide roller 7 is guided by the guide rail 5 and rolls in the forward / backward direction of the door body 4. Since it is constituted in this way, the guide rail 5 and the guide block 6 function as support means for supporting the door body 4 so as to be able to advance and retract.

  As shown in FIGS. 1B and 1C, the door body 4 includes a frame 8, a sash frame 9, and a transparent panel 10. The frame 8 is a frame-like frame that forms the outline of the door body 4, and is a structural member (strength member) that imparts strength to the door body 4 and maintains the shape of the door body 4. The sash frame 9 is a frame body that holds the transparent panel 10 and is fitted into the frame 8. A transparent panel 10 is fitted in the sash frame 9. Thus, the door body 4 includes a window in which the transparent panel 10 is fitted, and the sash frame 9 corresponds to a window frame that supports the transparent panel 10.

  The sash frame 9 has a cross-sectional shape (a cross-sectional shape obtained by cutting along the plane indicated by the line AA ′ in FIG. 1B) and has a groove-shaped portion with an open lower end. Constitutes the slide rail 11. Thus, in this embodiment, the entire slide rail 11 is constituted by the sash frame 9 and is not formed on the frame 8. In addition, a fall-stop fitting 12 is fixed to the door pocket 3. The tip of the fall-preventing metal fitting 12 is supported by the slide rail 11, and the anti-falling metal fitting 12 slides relative to the slide rail 11 in the forward / backward direction of the door body 4. In addition, the detailed structure of the slide rail 11 and the fall prevention metal fitting 12 is mentioned later.

  Next, a drive mechanism for moving the door body 4 back and forth with respect to the door pocket 3 will be described. As shown in FIG. 1B and FIG. 1C, a drive pulley 13 and a driven pulley 14 are arranged in the door pocket 3 with an interval in the forward / backward direction of the door body 4. A timing belt 15 is wound around the driving pulley 13 and the driven pulley 14. The timing belt 15 is connected to the door body 4 via a belt clamp 16. Therefore, when the driving pulley 13 is rotationally driven by an electric motor (not shown), the timing belt 15 advances and retreats between the driving pulley 13 and the driven pulley 14. When the timing belt 15 advances and retreats, the belt clamp 16 also advances and retreats. As a result, the door body 4 moves forward and backward with respect to the door pocket 3.

  In the state shown in FIG. 1B, when the drive pulley 13 is rotated in the clockwise direction (the direction indicated by the arrow CW), the door body 4 is moved to the right in FIG. 1B (the arrow in FIG. 1A). It moves in the direction indicated by BWD) and is pulled into the door pocket 3 as shown in FIG. Further, in the state shown in FIG. 1C, when the drive pulley 13 is rotated in the counterclockwise direction (the direction indicated by the arrow CCW), the door body 4 is moved to the left in FIG. ) In the direction indicated by the arrow FWD) and is pulled out of the door pocket 3 as shown in FIG. As described above, since the door body 4 is supported by the door pocket 3 via the guide rail 5 and the fall-preventing metal fitting 12, the upright state, that is, while maintaining the posture shown in FIG. , Advance and retreat with respect to the door pocket 3.

  Next, a detailed configuration of the slide rail 11 and the fall-preventing metal fitting 12 will be described. FIG. 2 is a cross-sectional view of a portion of the movable home fence 1 in the vicinity of the slide rail 11 and the fall-preventing metal fitting 12 cut along a plane indicated by line A-A ′ in FIG. As shown in FIG. 2, the slide rail 11 is at the upper part of the sash frame 9, and the cross-sectional shape thereof is a groove shape, the lower end is opened, and the horizontal direction, that is, the forward / backward direction of the door body 4. It extends to. The fall prevention metal fitting 12 is fixed to the door pocket 3 at the base portion 12a, and the arm portion 12b extends horizontally from the base portion 12a. The tip of the arm portion 12b is bent at a right angle, and the arm portion 12b has a bowl shape as a whole. The distal end portion of the arm portion 12 b is inserted into the slide rail 11 from the lower surface (open surface) of the slide rail 11. Sliding plates 12c are affixed to both the left and right sides of the tip of the arm portion 12b. The sliding plate 12 c is in contact with the inner surface of the slide rail 11. The sliding plate 12c is a flat plate made of a resin having a small friction coefficient (polyacetal, polyamide, polytetrafluoroethylene, polyphenylene sulfide, etc.). Since it is comprised in this way, the fall-prevention metal fitting 12 can slide freely in the extending direction of the slide rail 11.

  The two sliding plates 12c attached to the left and right sides of the tip of the arm portion 12b are in contact with the left and right inner walls of the slide rail 11, respectively. For this reason, the movement of the door body 4 in the left-right direction, that is, the movement of the door body 4 to the home side or the track side is restricted, and the door body 4 does not fall to the home side or the track side. Therefore, as shown in FIG. 2, the door body 4 advances and retreats with respect to the door pocket 3 while maintaining an upright state. Thus, the slide rail 11 and the fall-preventing metal fitting 12 function as a fall-preventing means for the door body 4.

  Further, in the movable home fence 1, the slide rail 11 is incorporated in the sash frame 9 and is not formed on the frame 8. Therefore, the strength of the door body 4 is not impaired by the fall-preventing means. As a result, it is not necessary to increase the thickness or reinforcement of the door body 4 to compensate for the decrease in strength, so that the door body 4 can be configured to be lightweight.
