Description

  The present invention relates to a platform door installed on a platform of a station.

  In order to prevent a person from falling from the platform of the station to the track side, safety measures are taken to install a platform door along the edge of the platform. Such platform doors are indispensable components not only for railways but also for new transportation systems that operate automatically. The installation of home doors continues to expand, and various home doors have been developed so far. For example, Patent Literature 1 discloses a home including a slide door that is slidable with respect to a door pocket, a slide mechanism that slide-connects between the slide door and the door pocket, and a driving means for the slide door. A door device is described.

JP 2000-016280 A

  In the prior art home door, the slide door is heavy, and therefore, a support structure for slidably supporting the slide door with respect to the door pocket must be configured firmly. In the conventional platform door, the slide door extends upward from the position near the upper surface of the platform and is supported at the lower edge of the slide door. The sliding door must be sufficiently robust against the moment caused by the crowd load acting on the track side. Therefore, the prior art platform doors are heavier and larger, which increases the manufacturing cost.

  Also, installing a platform door on the platform can reduce the labor of station staff located on the platform for safety confirmation when the train arrives, in addition to preventing falling people. However, there is a problem that it becomes impossible to see the track side from the platform side. In particular, there is a problem that even if a person is hiding or an object is placed behind the door pocket of the platform door, the platform cannot be seen from the blind spot.

  Furthermore, conventional home doors often employ a structure that supports and guides a sliding door by means of a linear bearing that is often used in machine tools, precision equipment, and the like. is there.

  ・ Since linear motion bearings using rolling elements (ball contact) require high precision (flatness, etc.) on the mounting surface, it is strongly required to ensure accuracy that is not necessary for supporting and supporting the home door when manufacturing door pockets. This increases the cost.

  -If the flatness of the installation surface of the home door (installation base surface on the home floor surface) is insufficient, the operation of the linear motion bearing is hindered and the mechanical resistance during opening / closing operation increases.

  -Since the guide rail of the linear motion bearing is installed inside the door pocket, it becomes difficult (or impossible) to provide an emergency exit in the door pocket. It is also possible to solve this problem by installing the guide rail on the sliding door side, but in that case, the guide rail is coated with grease for lubrication, so the guide rail is attached to the part that touches the passenger's hand. I can't. Therefore, it becomes difficult to attach the guide rail to the slide door having a simple structure composed only of the frame-like member, and the cost of the home door cannot be reduced.

The present invention according to claim 1 is a platform door device disposed along an edge of the platform, and a base disposed at a predetermined interval upward from the upper surface of the platform by a plurality of legs . a door pocket attached to the base, pre-SL and sliding door formed movably provided frame shape with respect to the door case, a guide member of the opened U-shaped upwardly of the sliding door Along the movement path, the doors are spaced apart from the door tip side and the door bottom side. The lower edge member of the frame-like slide door is received and the slide door is slidably supported in the direction along the edge of the platform. a guide member for guiding and summarized as home door apparatus comprising abutting follower on the upper surface of the lower edge member of the sliding door.

Two sets of guide members for guiding the slide door in a direction parallel to the track are installed on the upper surface of the base, and a liner attached to the surface of the guide member and a part of the frame-like member constituting the slide door (lower edge) The sliding door is guided while being in contact with the member. That is, by using a part of the frame-shaped member (lower edge member) constituting the slide door as a guide rail, it is not necessary to install the guide rail inside the door pocket.
The slide door may be formed of a frame body made up of a plurality of extruded section members.

  According to the present invention, by disposing the base above the upper surface of the platform and disposing the sliding door above the base, the blind spot when the track side is viewed from the platform side is reduced, Since the moment acting on the support guide mechanism is reduced by the crowd load acting on the upper edge of the slide door from the platform side to the track side, the support guide mechanism can be simplified, thus reducing the manufacturing cost of the platform door device. It becomes possible to do.

  In addition, the sliding door is supported and guided by a simple mechanism without using linear motion bearings made for machine tools and precision machines, which reduces the required accuracy when manufacturing the door pocket and reduces manufacturing costs. In addition, since it is not necessary to install a guide rail in the door pocket, it is easy to install an emergency exit in the door pocket.

Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
In the embodiment, the platform door system includes a plurality of platform door units 100. The home door unit 100 is arranged at a predetermined interval along the longitudinal edge of the platform P, and the adjacent home door unit 100 defines an opening S through which passengers come and go, for example. The home door unit 100 includes a base 108 fixed to the platform P by legs 126, a door pocket 102 attached to the base 108, and a sliding door that can be moved forward and backward in the horizontal direction to open and close the opening S. 16, 18 and a driving device 140 (FIG. 8) for the sliding doors 16 and 18 are provided.

  The base 108 is arranged and fixed with a plurality of legs 126 spaced apart from the upper surface of the platform P. Thus, by separating the base 108 upward from the upper surface of the platform P, it is possible to confirm that a person is hiding outside the door pocket 102 or that an object is placed on the bottom side of the base 108 from the platform P side. It becomes visible through. Also, the door pocket 102 can be downsized. Further, by separating the base 108 upward from the upper surface of the platform P, the length H of the slide doors 16 and 18 is shortened, the moment due to crowd load is reduced, and the slide doors 16 and 18 are reduced. It becomes possible to simplify the rigidity of itself and the structure of the support guide means of the slide doors 16 and 18 described later.

  The base 108 has a pair of stationary bases 104 fixed to the platform P by legs 126, and a pair of movable bases 106 provided so as to be rotatable in the horizontal direction with respect to the stationary base 104. (See FIG. 5). Legs are not provided below the movable base 106. The door pocket 102 is attached to each of the stationary door pockets 120 via a pair of hinges 124 and is rotated in the horizontal direction together with the movable base 106. It has a free pair of movable door pockets 130. More specifically, the movable door pocket 130, together with the movable base 106, can be rotated horizontally around the hinge 124 between the closed position shown in FIGS. 1, 2, and 4 and the open position shown in FIG. It has become.

  A control panel (not shown) for controlling the home door unit 100 can be disposed under the base 108 so as to be exposed to the outside. By disposing the control panel outside the door pocket 102, the inside of the control panel can be accessed without removing the cover of the door pocket 102, and maintenance work is facilitated.

  In the present embodiment, the guide means for the sliding doors 16 and 18 are offset from each other in the door pocket 102 in a direction perpendicular to the opening and closing direction of the sliding doors 16 and 18, and the two sliding doors 16 and 18. Are arranged and housed in the door pocket 102 side by side. That is, the door pocket 102 is formed so as to accommodate the two sliding doors 16 and 18 in a sliding manner. The upper portion of the door pocket 102 is cut off at both ends thereof, and the sliding doors 16 and 18 are exposed at the door tips even when they are in the open position stored in the door pocket 102 as shown in FIG. It is like that. This prevents an accident in which a finger or the like is pulled between the door pocket 102 and the slide doors 16 and 18 when the slide doors 16 and 18 are pulled into the open position. Further, by cutting out a part of the door pocket 102 in this way, the blind spot when the track side is viewed from the platform side is reduced. In the present embodiment, the door pocket 102 has a cover 120a that covers the door tips of the lower edge members 16d and 18d (FIG. 10) of the slide doors 16 and 18.

  As shown in FIGS. 10 to 14, the slide doors 16, 18 have door tip members 16 a, 18 a, door bottom members 16 b, 18 b, upper edge members 16 c, 18 c, and lower edge members 16 d, 18 d, and are rectangular. It consists of the frame body formed in. This frame is made of, for example, a plurality of section members having a cross section as shown in FIG. 14 and cut into an appropriate length of an appropriate metal material, for example, an aluminum extrusion molding material, for example, screws or bolts. It can be formed using an appropriate joining means such as fastening. The cushions 17 and 19 attached to the doors of the slide doors 16 and 18 have a protruding portion 11 that extends downward beyond the lower edge members 16d and 18d.

  In this way, the slide doors 16 and 18 are formed from a frame body, and the installation height thereof is separated from the floor surface of the platform P by a certain amount (installed at a high position and the lower part is omitted). , 18 may cause the leading ends of the frame-like slide doors 16 and 18 to collide with the head and face of an infant or a standing infant on the stroller and cause injury. By providing the cushions 17 and 19 with the protruding portions 11 extending downward beyond the lower edge members 16d and 18d, such an accident can be prevented. That is, by extending the cushions 17 and 19 to a position lower than the head and face of the infant at a lower position (position lower than the side frame of the stroller), the head and face are pierced by the tip of the door. Such a situation is avoided.

  The guide members 160 and 162 serving as guide means are substantially U-shaped block members having arm members 160 a and 162 a extending upward, and are fixed to the upper surface of the stationary base 104. Lower edge members 16d and 18d of the sliding doors 16 and 18 are disposed between the arm members 160a and 162a extending above the guide members 160 and 162. In the arm members 160a, 162a of the guide members 160, 162, a liner 164a (see FIGS. 7, 27, 28) is provided on the inner surface facing the lower edge members 16d, 18d of the slide doors 16, 18. Further, a liner 164b is provided on the inner surface facing the bottom surfaces of the lower edge members 16d and 18d of the slide doors 16 and 18 between the arm members 160a and 162a of the guide members 160 and 162.

  The sliding doors 16 and 18 are guided in the horizontal direction by guide members 160 and 162 mounted on the stationary base 104, and each of the sliding doors 16 and 18 is driven by a driving device 140 mounted on the stationary base 104 as shown in FIG. It is driven in a horizontal linear direction between a closed position where they abut each other at the front end or the door tip and an open position stored in the door pocket 12, as shown in FIG.

  Referring to FIG. 8, the driving device 140 includes a bracket 142 fixed to the stationary base 104, a driving motor 144 attached to one side surface of the bracket 142, a driving pulley 146, idle pulleys 148 and 154, and a support roller 156, 158. The drive pulley 146 is disposed on the opposite side of the drive motor 144 and is attached to a drive shaft 146 a that is horizontally oriented and rotatably supported by the bracket 142. The drive shaft 146a is connected to an output shaft (not shown) of the drive motor 144 via a speed reducer (not shown). The driving device 140 and the guide member 160 on the distal end side are disposed in a cover 120a that covers the door tips of the lower edge members 16d and 18d (FIG. 11) of the sliding doors 16 and 18 in the stationary door pocket 120. .

  The idle pulley 148 on the rear end side is rotatably attached to the support shaft 150 by a retaining ring or a C-shaped clip 152a and a washer 150b. Support rollers 156 and 158 are disposed on both sides of the leading idle pulley 154. The support roller 156, idle pulley 154, and support roller 158 are supported by a retaining ring or C-shaped clip 152a and washer 152b. 152 are attached to rotate independently of each other.

  Referring to FIG. 9, the support rollers 156 and 158 on the distal end side are radially outermost first annular portions 156a and 158a, and second annular portions provided inside the first annular portions 156a and 158a. 156b, 158b, a third annular portion 156c, 158c provided inside the second annular portion 156b, 158b, and a metal hollow cylindrical shape provided inside the third annular portion 156c, 158c Cores 156d and 158d are provided.

  The first annular portions 156a and 158a and the third annular portions 156c and 158c are made of an elastic material such as urethane rubber, and the second annular portions 156b and 158b are made of a metal material such as stainless steel. . In particular, the first annular portions 156a and 158a are formed of an elastic material harder than the third elastic portions 156c and 158c. Further, bearing bushes 156e and 158e can be disposed on the inner peripheral surfaces of the cores 156d and 158d.

  As described above, when the hardness of the inner third annular portions 156c and 158c is made lower than that of the outer first annular portions 156a and 158a, a large load is applied to the slide doors 16 and 18 in the downward direction in the vertical direction. Further, when the inner third annular portions 156c and 158c are deformed (collapsed), the lower edge members 16d and 18d of the slide doors 16 and 18 come into contact with the liner 164b, and a load acting on the slide doors 16 and 18 is applied. It becomes possible to load the liner 164b. This reduces the contact surface pressure between the outermost first annular portions 156a and 158a of the support rollers 156 and 158 and the lower edge members 16d and 18d, and the support rollers 156 and 158 or the lower edge members 16d and 18d. It is prevented that permanent deformation occurs.

  As shown in FIG. 7, the idle pulleys 148, 154 are disposed in the grooves 13 (see FIG. 14) of the lower edge member of the slide doors 16, 18, and the support rollers 156, 158 are located under the slide doors 16, 18. It contacts the lower surface or the flank 13a (see FIG. 14) on both sides of the groove 13 of the edge member. Thus, a part of the section member constituting the frame of the slide doors 16 and 18 is used as a guide rail. A belt 166 is stretched around the leading pulley 154, the driving pulley 146, and the trailing pulley 148, and each end of the belt 166 is attached to the slide door 16, the mounting brackets 166a and 166b. 18 are coupled to the front end (door tip) side and the rear end (door bottom) side of the lower edge members 16d, 18d. The drive pulley 146 may be a toothed pulley having teeth arranged at equal intervals along the outer peripheral surface. The belt 166 can be a toothed belt having a plurality of teeth adapted to the teeth of the drive pulley 146. Thus, when the drive pulley 146 is rotationally driven by the drive motor 144, the slide doors 16 and 18 move back and forth in the horizontal direction according to the rotational direction of the drive pulley 146.

  Further, a follower 134 disposed on the rear end side in the moving direction of the slide doors 16 and 18 is disposed in the stationary door pocket 120. The follower 134 engages with the upper surfaces of the lower edge members 16d and 18d of the slide doors 16 and 18, and restricts the upward movement of the slide doors 16 and 18. A steady rest 138 having a liner similar to the liners of the guide members 160 and 162 is disposed inside the vicinity of the upper end of the stationary door pocket 120. The liner of the steady rest 138 is arrange | positioned so that the side surface of the upper edge parts 16c and 18c of the sliding doors 16 and 18 may be faced. Further, in the movable door pocket 130, a follower 132 (FIG. 4) that supports the bottom surfaces of the lower edge members 16d and 18d on the rear end (door bottom) side of the slide doors 16 and 18 is disposed.
