(First embodiment)
FIG. 1 (A) is a front view of the movable home fence 1 according to the first embodiment of the present invention as viewed from the home side, and FIG. 1 (B) is a side view of the movable home fence 1. As shown in FIGS. 1 (A) and 1 (B), the movable platform fence 1 is fixed to the floor 2 of the platform of the railway station, and is attached to the fixed portion 3 so as to freely advance and retract. And a door body 4 for opening and closing a train entrance. The fixing portion 3 includes two columnar members 5 that are erected and fixed to the floor surface 2, and an upper horizontal frame 6 and a lower horizontal frame 7 that are fixed to the columnar member 5. The upper horizontal frame 6 and the lower horizontal frame 7 are arranged at an interval in the vertical direction, and the door body 4 is arranged between the upper horizontal frame 6 and the lower horizontal frame 7.

  The door body 4 is composed of horizontal frames 4h and 4l arranged at intervals in the vertical direction and a vertical frame 4v connecting the horizontal frames 4h and 4l to each other on the door end side. That is, the door body 4 is configured by a frame structure in which a “U” -shaped frame is laid down.

  As shown in FIGS. 1A and 1B, a panel 8 and an access door 9 are attached to the front surface of the movable home fence 1 on the home side. The panel 8 is a plate-like member that covers the front side of the fixed portion 3 on the home side, and is fixed to the fixed portion 3. The access door 9 is a plate-like member arranged at a position on the front side of the home side of the fixed portion 3 so as to cover a driving device described later, and is attached to the fixed portion 3 via a hinge 10. That is, the access door 9 is a hinged door that swings around the hinge 10.

  FIGS. 1C and 1D are diagrams illustrating the internal structure and operation of the movable home fence 1. FIG. 1C shows a state in which the door body 4 is drawn into the fixed portion 3, that is, the movable home fence 1 in a fully opened state, and FIG. 1D shows that the door body 4 is pulled out of the fixed portion 3. Each of the movable home fences 1 in the closed state, that is, in the fully closed state is shown. As shown in FIGS. 1C and 1D, a linear guide rail 11 extending in a direction in which the door body 4 advances and retreats is fixed to the upper horizontal frame 6 of the movable home fence 1. Two linear guide blocks 12 are slidably attached to the linear guide rail 11, and the linear guide block 12 is fixed to the door body 4. That is, the door body 4 is slidably supported by the linear guide rail 11 via the linear guide block 12. Thus, since the door body 4 is supported by the fixed part 3 via the linear guide block 12 and the linear guide rail 11, it can freely advance and retreat with respect to the fixed part 3. Therefore, the door body 4 can freely move between the position shown in FIG. 1C and the position shown in FIG.

  As shown in FIGS. 1C and 1D, a pinion 13 and an electric motor 14 that rotationally drives the pinion 13 are fixed to the fixed portion 3 of the movable home fence 1. A flexible rack 15 is engaged with the pinion 13. One end of the flexible rack 15 is fixed to the door body 4 via a clamp 16. A rack guide body 17 that supports the flexible rack 15 so as not to bend between the pinion 13 and the clamp 16 is fixed to the fixing portion 3. The other end of the flexible rack 15 is drawn into a rack container 18 fixed to the fixing portion 3. The rack housing 18 is a sheath-like member that houses the flexible rack 15.

That is, the access doors 9a and 9b may be sliding doors.

(Third embodiment)
In the second embodiment, two sets of the upper horizontal frame 6 and the lower horizontal frame 7 are arranged on the home side and the track side of the columnar member 5, and the upper horizontal frame 6 and the lower horizontal frame 7 arranged on the home side. An example is shown in which the door body 4a is supported by a set of the above, and the door body 4b is supported by a set of the upper horizontal frame 6 and the lower horizontal frame 7 arranged on the track side. In the third embodiment, an example in which two door bodies 4a and 4b are supported by a pair of upper horizontal frame 6 and lower horizontal frame 7 is shown. As shown in FIGS. 5A and 5B, the movable home fence 1 according to the third embodiment includes only one set of an upper horizontal frame 6 and a lower horizontal frame 7 (not shown in FIG. 5). I have. The two door bodies 4 a and 4 b included in the movable home fence 1 are arranged in series and supported by a single set of the upper horizontal frame 6 and the lower horizontal frame 7. Access doors 9 a and 9 b are arranged in the center of the front side of the fixed portion 3 of the movable home fence 1 on the home side, and are attached to the fixed portion 3 via hinges 10, respectively. The access door 9a covers the driving device 19a that drives the door body 4a, and the access door 9b covers the driving device 19b that drives the door body 4b. Moreover, the panel 8a is arrange | positioned adjacent to the access door 9a, and the panel 8b is arrange | positioned adjacent to the access door 9b at the both ends of the front side of the fixed side 3 of the movable home fence 1 respectively. The panels 8a and 8b are attached to the fixed portion 3 via slide rails (not shown). Therefore, the panels 8a and 8b can be slid in parallel with the direction in which the door body 4 advances and retreats.

  Since the movable home fence 1 according to the third embodiment has the above-described configuration, the access doors 9a and 9b are swung around the hinge 10 as shown in FIG. 9a and 9b can be opened in double doors. If the access door 9a is opened, the drive device 19a that drives the door body 4a can be accessed from the outside of the movable home fence 1 to perform maintenance and inspection of the drive device 19a. If the access door 9b is opened, the drive device 19b for driving the door body 4b can be accessed from the outside of the movable home fence 1 to perform maintenance and inspection of the drive device 19b. Moreover, the panels 8a and 8b can be slid in parallel with the direction in which the door body 4 advances and retreats so that the front side of the fixed portion 3 on the home side can be greatly opened. Therefore, inspection and maintenance of various devices attached to the fixed portion 3 are facilitated.

  The structure of the movable home fence 1 which concerns on 3rd Embodiment is not limited to what was mentioned above. Instead of providing two access doors 9a and 9b, one access door 9 may be attached to the fixed portion 3 via a hinge 10 as shown in FIG. In this case, if the access door 9 is opened, the drive device 19a for driving the door body 4a and the drive device 19b for driving the door body 4b can be accessed from the outside of the movable home fence 1.

  Alternatively, the two access doors 9a and 9b may be eliminated, and the entire front side of the fixed portion 3 on the home side may be covered with the panels 8a and 8b as shown in FIG. 6B. Then, the panels 8a and 8b may be attached to the fixed portion 3 via slide rails (not shown) so that the panels 8a and 8b can slide in parallel with the direction in which the door body 4 advances and retreats. If such a configuration is selected, it is possible to access the driving device 19a for driving the door body 4a from the outside by sliding the panel 8a. Further, by sliding the panel 8b, it is possible to access the driving device 19b that drives the door body 4b from the outside. That is, in this case, the panels 8a and 8b themselves function as access means.

(Fourth embodiment)
The drive device 19 involved in the operation of the door body 4 in the movable home fence 1 is not limited to that disposed between the upper horizontal frame 6 and the lower horizontal frame 7. In some cases, an electric / electronic device for controlling the electric motor 14 is disposed above the upper horizontal frame 6. In 4th Embodiment, the structural example in case the drive device 19 is arrange | positioned above the upper horizontal frame 6 is shown.

  In the movable home fence 1 according to the fourth embodiment, as shown in FIG. 7A, a drive device 19 is fixed to the upper surface of the upper horizontal frame 6. Here, the drive device 19 is an electric and electronic device that controls an electric motor (not shown) included in the movable home fence 1. A hood 21 is placed on the upper surface of the upper horizontal frame 6, and the drive device 19 is covered with the hood 21. The hood 21 is a box-shaped member whose bottom surface is open, and is attached to the upper horizontal frame 6 via a hinge 10 disposed on the track side, and swings around the hinge 10. Therefore, as shown in FIG. 7 (B), the hood 21 swings around the hinge 10, is flipped up to the track side, and is released. Therefore, when the hood 21 is opened, the drive device 19 can be easily accessed from the home side.

  FIG. 8A is a partial side view of the movable home fence 1 according to the fourth embodiment, and shows a state where the hood 21 is in the open position. FIG. 8B is a partial side view of the movable home fence 1 and shows a state where the hood 21 is in the closed position. As shown in FIG. 8A, when the hood 21 is in the open position, the end surfaces of the linear guide rail 11 and the linear guide block 12 are exposed. Therefore, in this state, the state of the linear guide rail 11 and the linear guide block 12 can be visually inspected. In addition, oil and grease can be supplied to the linear guide rail 11 and the linear guide block 12. Further, as shown in FIG. 8B, when the hood 21 is in the closed position, the linear guide rail 11 and the linear guide block 12 are covered by the hood 21. Therefore, in this state, the linear guide rail 11 and the linear guide block 12 are protected against inadvertent access from the outside. As described above, the hood 21 is attached to the fixed portion 3 so as to be movable between the open position and the closed position, so that the drive device 19 can be accessed from the outside of the movable home rail 1 when in the open position. Functions as an access means.

  In general, the movable platform fence 1 is exposed to a strong wind pressure caused by a train wind generated when the train travels or a natural wind such as a typhoon. When the movable home fence 1 is exposed to a strong wind pressure, a problem may occur if the mounting strength of the component parts is low or there is rattling. When the panel 8 is detachably attached to the fixing portion 3, the attachment strength is lower than when the panel 8 is fixed to the fixing portion 3. When the panel 8 is detachably attached to the fixed portion 3, the panel 8 may be rattled.

  A snap lock is known as means for detachably attaching the panel 8 to the fixing portion 3. When a snap lock is used to attach the panel 8 to the fixing portion 3, it is necessary to secure a space for arranging the snap lock in the hood 21. However, since the movable home fence 1 is required to be downsized and the drive device 19 is already arranged in the hood 21, it is not possible to secure a space for arranging the snap lock in the hood 21. There is a problem that it is difficult. Further, even if the panel 8 is fixed with a plurality of snap locks, there is a problem that it is difficult to effectively fix the panel 8 and suppress the occurrence of rattling.

  Therefore, in the movable home fence 1 according to the fourth embodiment, the above problem is solved by selecting the following configuration. That is, as shown in FIGS. 7B and 8A, the panel 8 included in the movable home fence 1 is supported by the fixed portion 3 via the slide frame 22. A cushion member 23 is fixed to a part of the hood 21 that faces the panel 8 when the hood 21 is in the closed position. Then, as shown in FIG. 8B, the cushion member 23 has a thickness Th that can contact the panel 8 and press the panel 8 when the hood 21 is in the closed position.

  Since the movable home fence 1 according to the fourth embodiment has the above-described configuration, the panel 8 can be slid and removed from the fixed portion 3 when the hood 21 is in the open position. When the hood 21 is in the closed position, the panel 8 is pressed against the fixing portion 3 by being pressed by the cushion member 23, so that the panel 8 is fixed to the fixing portion 3. Further, the occurrence of rattling of the panel 8 is suppressed. As shown in FIG. 7B, the cushion member 23 extends in the longitudinal direction of the hood 21, that is, in the length direction of the platform on which the movable platform fence 1 is installed. Therefore, when the hood 21 is in the closed position, the cushion member 23 can abut against the panel 8 and press the panel 8 in all regions in the width direction of the panel 8. As a result, the occurrence of rattling of the panel 8 is effectively suppressed.

  As described above, in the movable home fence 1 according to each of the embodiments described above, the access door 9 and the hood 21 function as an access unit that enables access to the drive device 19 from the outside of the movable home fence 1.
