Description

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

  Conventionally, there has been known a movable fence that is installed along the edge of the platform on the track side to prevent falls from the platform of the station and contact with the train, and the door can be opened and closed by a door. An example of such a movable fence is shown in Patent Document 1 below.

  The movable fence disclosed in the following Patent Document 1 is provided so as to be able to advance and retreat from the door pocket, the right door body provided so as to be able to advance and retract from the door pocket to one side, and the one side opposite to the one side. Left side door body.

  The door pocket is divided into an end portion on the one side and an end portion on the opposite side of the door pocket, and connects a pair of vertical frames extending in the vertical direction between the upper portions of the pair of vertical frames. The upper horizontal frame extending in the advancing / retreating direction of the door body and the lower portions of the pair of vertical frames are connected to each other, and the lower horizontal frame extending in the advancing / retreating direction of the door body and the end portion on the one side of the upper horizontal frame An upper linear rail attached to the upper surface of the upper horizontal frame so as to extend to a substantially central portion in the longitudinal direction, and extends from an end opposite to the one side of the lower lateral frame to a substantially central portion in the longitudinal direction.

  However, in the conventional movable fence described above, the strength of the door pocket cannot be improved by using the linear rail, and the slide block of each door body or each linear rail of the door pocket becomes heavily worn. There is a problem that it is difficult to maintain smooth sliding of the slide block with respect to the linear rail when an external force is applied.

  Specifically, in the above-described movable fence, the upper and lower linear rails do not connect the vertical frames on the left and right sides, and therefore the strength of the door pocket cannot be improved by these linear rails. Moreover, in said movable fence, the load applied by the cantilever support of the door body which advanced from the door pocket is supported by the hook of the protrusion part of the inner surface of the recessed part of the slide block with respect to the groove part formed in the both sides | surfaces of a linear rail. As a result, a large load concentrates on the protrusion of the slide block, and wear of the protrusion becomes severe. Moreover, since the slide block of the door body is engaged only with the upper half part or the lower half part of the linear rail of the door pocket, the holding force of the engagement of the slide block with the linear rail is small. For this reason, when an external force is applied to the door body that has advanced from the door pocket, a shift occurs in the engagement state of the slide block with respect to the linear rail, and smooth sliding of the slide block with respect to the linear rail is impaired.

  The present invention has been made in order to solve the above-described problems, and its purpose is to improve the strength of the door pocket using a guide member for guiding the forward and backward movement of the door, and to slide the door. And a movable fence capable of maintaining smooth sliding of the sliding member of the door even when an external force is applied to the door.

  In order to achieve the above object, a movable fence according to the present invention is a movable fence provided on a platform, and can move forward and backward from the door pocket installed on the platform and the edge of the platform on the track side. A door provided so that the first end plate portion constituting one end face of the door pocket in a direction along the track-side edge of the platform, and the one of the door pockets. A second end plate portion constituting an end surface on the other side opposite to the side, and extending in a direction along an edge on the track side of the platform, and connecting the first end plate portion and the second end plate portion to each other. And a guide member that cantilever and supports the door so that the door can advance and retreat, and the door includes a sliding member having an insertion hole through which the guide member is inserted. Provided, the sliding member, It is supported by the guide member in a slidable state along the serial guide member.

  In this movable fence, the guide member that is inserted into the insertion hole of the sliding member of the door and cantilever-supports the door connects the first end plate portion and the second end plate portion on both sides of the door pocket. In addition to the original role of guiding the forward / backward movement of the door, the member plays a role as a strength member that resists the load applied by the cantilever support of the door. For this reason, in this movable fence, the strength of a door pocket can be improved using the guide member which guides the forward / backward movement of the door. In this movable fence, since the guide member is inserted into the insertion hole of the sliding member of the door, the load applied by the cantilever support of the door is distributed and supported over a wide range of the inner surface of the insertion hole of the sliding member. In addition, when an external force is applied to the door that has advanced from the door pocket, it is possible to suppress a shift in the inserted state of the sliding member with respect to the guide member. For this reason, it is possible to reduce the wear of the sliding member as compared with the case where the load of the door is concentrated on the protrusion of the slide block fitted in the groove of the linear rail like a conventional movable fence, and the door Even when an external force is applied to the door, smooth sliding with respect to the guide member of the sliding member of the door can be maintained.

  In the movable fence, the guide member is preferably constituted by a hollow pipe.

  According to this configuration, it is possible to reduce the weight of the guide member as compared to a case where the guide member is formed of a solid bar.

  In the movable fence, it is preferable that the guide member has an outer peripheral surface that is circular in a cross section orthogonal to the axial direction.

  According to this configuration, wear of the guide member and the sliding member can be reduced, parts procurement can be facilitated, and member costs can be reduced. Specifically, for example, when the outer surface of the guide member has a shape that forms a square shape in a cross section orthogonal to the axial direction, the corner of the outer surface of the guide member hits the sliding member, resulting in wear. Easy to progress. On the other hand, in this structure, since the outer peripheral surface of the guide member forms a circle in a cross section orthogonal to the axial direction, the contact at the corner as described above does not occur. For this reason, wear of the guide member and the sliding member can be reduced. In addition, when the outer surface of the guide member is square, it is necessary to use a rectangular sliding member corresponding to the rectangular outer surface, but such a rectangular sliding member is not a general part, Parts procurement becomes complicated and the cost of members increases. On the other hand, in this structure, since the outer peripheral surface of a guide member is circular, a general round-shaped sliding member can be used, component procurement is easy and the cost of a member can be reduced.

  In the movable fence, the sliding member may be constituted by a bush, or may be constituted by a bearing.

  According to these configurations, a smooth sliding state of the sliding member with respect to the guide member can be maintained without supplying lubricating oil to the sliding member. For this reason, the smooth sliding state of the sliding member with respect to the guide member can be maintained while simplifying the maintenance work. In addition, the processing accuracy of bushes and bearings is not required to be as high as the processing accuracy of linear rails and slide blocks used in conventional movable fences. Can be reduced. In addition, the fitting of the sliding member consisting of a bush or a bearing and the guide member does not require as high accuracy as the accuracy required for the engagement between the linear rail of the conventional movable fence and the slide block. The complexity of the work of assembling the constituent members can be reduced.

  In the movable fence, a plurality of the guide members are provided in the door pocket, the plurality of guide members are arranged at different height positions, and the door is supported by the plurality of guide members. It is preferable to have a sliding member.

  According to this configuration, since the load applied by the cantilever support of the door can be shared by the plurality of guide members, the strength of the door bag with respect to the load applied by the cantilever support of the door can be further improved. In addition, in this configuration, since the plurality of guide members are arranged at different height positions, compared to the case where the plurality of guide members are arranged in the horizontal direction at the same height position, the piece of the door Greater strength can be exerted against the load in the direction of gravity applied by the holding support.

  In the movable fence, the movable fence, as the door, is provided with a first door provided so as to be able to advance and retreat from the door pocket to the one side along an edge on the track side of the platform, and a track of the platform. A second door provided so as to be capable of advancing and retracting from the door pocket to the other side along an edge of the side, wherein the door bag serves as the guide member, the first end plate portion and the second end. A first guide member that connects the plate portions to each other and guides and supports the first door so that the first door can be advanced and retracted; and the first end plate portion and the second end A second guide member that connects the plate portions to each other and guides and supports the second door so that the second door can advance and retreat; and the first guide member and the first guide 2 The guide members are arranged in a line in the vertical direction in the door pocket. Which is preferably location.

  In this configuration, the first door is cantilevered and supported by the first guide member in the door pocket, and the second door is cantilevered and supported by the second guide member, and is orthogonal to the track-side edge of the platform in the door pocket. A space can be secured on one side of the first guide member and the second guide member in the horizontal direction. For this reason, the layout of apparatuses which require a comparatively large space, such as a control apparatus, can be easily performed in the door pocket.

  As described above, according to the present invention, the strength of the door pocket is improved by using the guide member that guides the forward and backward movement of the door, the wear of the sliding member of the door is reduced, and an external force is applied to the door. A movable fence capable of maintaining smooth sliding of the sliding member of the door even when applied is provided.
