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 that is installed on the platform of a railway station and opens and closes according to the arrival and departure of railway vehicles. Generally, a movable platform fence includes a door pocket fixed to a platform and a door that moves on a rail provided in the door pocket and moves forward and backward with respect to the door pocket.

Various attempts have been made to construct such a movable home fence in a lightweight and inexpensive manner. For example, the movable home fence described in Patent Document 1 comprises a main pipe formed by bending a door in a U shape, a sub pipe provided substantially horizontally, and a box-shaped member (supporting portion). To reduce the weight of the door. Further, Patent Document 1 claims that if such a structure is selected, the door can be formed at low cost.

Japanese Patent No. 33060555

However, the movable home fence described in Patent Document 1 has a problem that the weight reduction and cost reduction of the door have not been sufficiently achieved yet. For example, since the box-shaped member (supporting portion) is an indispensable component, there is a problem that the weight of the door increases by the amount of the box-shaped member. Further, there is a problem that the manufacturing cost increases due to the labor involved in manufacturing the box-shaped member and connecting the box-shaped member and the main pipe or the like. Further, if the weight of the door is large, the power required to open and close the door also increases, so that there is a problem that the operating cost of the movable platform fence increases.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a lightweight and inexpensive movable home fence.

The movable home fence according to the present invention is a movable home fence including a fixed portion fixed to the platform, a door portion that slides with respect to the fixed portion, and a drive portion that moves the door portion forward and backward with respect to the fixed portion. Therefore, the fixing portion includes a columnar member erected at the installation location and a plurality of horizontal frames fixed to the columnar member and extending in the sliding direction of the door portion, and the plurality of horizontal frames are spaced apart in the vertical direction. The doors are arranged at intervals to form a fixed fence, and the doors are provided with a plurality of horizontal fences that are arranged at intervals in the vertical direction and extend in the sliding direction of the doors, and the plurality of horizontal fences are on the door end side. At the end, coupled with a common door end member, at least one horizontal fence is directly supported by one horizontal frame, with the horizontal fence between the horizontal fence and the horizontal frame. Only the supporting means that supports the door portion so as to be able to move forward and backward in the sliding direction intervenes.

According to the present invention, since the fixed portion of the movable home fence is formed by the columnar member and the horizontal frame, and the door portion of the movable home fence is formed by the door end member and the horizontal fence, the structure of the movable home fence is simplified. The door. As a result, the weight of the movable home fence is reduced. In addition, the manufacturing cost of the movable home fence is reduced.

The third guide member 29 is a member that is arranged below the second guide member 28, one end of which is fixed to the fixing portion 3, and the other end of which extends toward the door end, and is in a fully open state (FIG. 7 (a)). In the state shown in (1), it is configured to be inserted into the lower horizontal fence 12. The push-pull chain 24 is guided by the third guiding member 29 and advances and retreats with respect to the lower horizontal fence 12. The specific shapes of the first to third guide members 27 to 29 will be described later.

By the way, in the state shown in FIG. 7A, when the sprocket wheel 25 is rotated counterclockwise (arrow CCW direction), the push-pull chain 24 is moved to the door end side (-X direction, arrow FWD) in the upper horizontal frame 7. Move in the direction) and push the door portion 4 toward the door end side. As a result, the door portion 4 moves to the door end side and is in the state shown in FIG. 7 (b). That is, it is fully closed. Further, the push-pull chain 24 in the columnar member 6 in the fully open state is pushed into the upper horizontal frame 7 in the fully closed state, and the push-pull chain 24 in the lower horizontal fence 12 is pulled out. .. During this time, the push-pull chain 24 is displaced by the first to third guide members 27 to 29, and moves back and forth along the above-mentioned path. That is, the push-pull chain 24 is guided by the first to third guide members 27 to 29 to move forward and backward.

When the sprocket wheel 25 is rotated clockwise (arrow CW direction) in the state shown in FIG. 7B, the push-pull chain 24 moves to the door tail side (+ X direction, arrow BWD direction) in the upper horizontal frame 7. Then, the door portion 4 is pulled back to the door end side. As a result, the door portion 4 moves to the door end side and is in the state shown in FIG. 7 (a). In other words, it will be in a fully open state. Further, the push-pull chain 24 that was in the upper horizontal frame 7 in the fully closed state was pulled out in the fully open state, and the push-pull chain 24 that was in the columnar member 6 was put in the lower horizontal fence 12. Be pushed in. During this time, the push-pull chain 24 is displaced by the first to third guide members 27 to 29, and moves back and forth along the above-mentioned path. That is, the push-pull chain 24 is guided by the first to third guide members 27 to 29 to move forward and backward.

In this way, when the movable platform fence 1 opens and closes, the push-pull chain 24 moves between the upper horizontal frame 7 and the lower horizontal fence 12. During this time, since the push-pull chain 24 is guided by the first to third guide members 27 to 29, the push-pull chain 24 is smoothly moved and the generation of abnormal noise is small.

Further, in the fully opened state, the push-pull chain 24 pulled out from the upper horizontal frame 7 is pushed into the lower horizontal fence 12, so a space for accommodating the pulled-out push-pull chain 24 is separately prepared in the fixed portion 3. No need. Therefore, the fixed portion 3 can be designed compactly.

Here, the configuration of the push-pull chain 24 will be described. As shown in FIGS. 8A and 8B, the push-pull chain 24 is configured by alternately arranging the link 30 and the joint piece 31 and connecting the link 30 and the joint piece 31 with a pin 32. There is. Further, the link 30 has a shape in which the contour of the upper corner portion 30a forms a right angle and the contour of the lower side corner portion 30b forms an arc in the side shape shown in FIG. 8A. Therefore, the push-pull chain 24 bends in the direction shown in FIG. 8C, but does not bend in the opposite direction.

Therefore, when the push-pull chain 24 is arranged so that the load is applied in the direction indicated by the arrow W in FIG. 8A, even if pressure is applied to the push-pull chain 24 in the direction indicated by the arrow T, the push-pull chain 24 does not bend. That is, in the state shown in FIG. 8A, the thrust can be transmitted by using the push-pull chain 24. The detailed configuration of the push-pull chain 24 according to the present embodiment is disclosed in Japanese Patent Application Laid-Open No. 2002-106647. If necessary, refer to the above publication.

Further, as shown in FIG. 9, the first to third guide members 27 to 29 have a groove-shaped or gutter-shaped cross section. Since the first to third guide members 27 to 29 have such a shape, the displacement of the push-pull chain 24 is restricted, and the push-pull chain 24 is guided in the direction intended by the designer. The second and third guide members 28 and 29 may be formed of a hollow pipe because the bracket 26 does not need to be exposed unlike the first guide member 27. That is, the push-pull chain 24 may be passed through the hollow pipe.

Further, the first and third guide members 27 and 29 may be configured to be expandable and contractible. For example, as shown in FIGS. 10A to 10C, the first guiding member 27 is divided into a first member 27a and a second member 27b, and the second member 27b is nested in the first member 27a. , You may move back and forth freely with each other.
