  Therefore, the problem to be solved by the present invention is a safety structure that prevents the passenger waiting on the platform from falling to the home and does not catch the passenger's body or luggage during the lifting operation of the fence-like device, and Providing a fence-like device that reduces the overall burden of equipment by reducing the burden on the equipment on the fixing side by reducing the surface area that receives wind, thereby reducing the cost of reinforcing the equipment on the fixing side. The task is to do.

  In addition, providing a fence-like device that is easy to install and can be installed at low cost, and can be used in any open door position (supports various trains and considers driving skills of the driver). This is the issue.

  In addition, as in the case of train platforms, there are various usage scenes that have problems in terms of cost, the strength of the side equipment to which the fence-like devices are fixed, and the strength of the fence-like devices (such as fences and parking lots that prevent the entry of animals into the field) Therefore, an object of the present invention is to provide a fence-like device that can be applied even in those usage scenes.

This ensures passenger safety.

  When installing on a train platform, the shapes of the uppermost cylinder (101), the intermediate cylinder (102) and the lowermost cylinder (103) are taken into account when passengers waiting on the platform come into contact. It is preferable to have a shape with no corners (cylindrical shape, elliptical cylinder shape, rounded polygonal prism shape, etc.), and considering the strength of the equipment on the platform side (floor, beam, roof, etc.) A cylindrical shape that can be reduced is optimal.

  The elevating body fixing portion (40) includes a beam (401) for fixing the elevating body (10) at the position of the uppermost cylinder (101).

  The lifting / lowering body fixing portion support portion (50) includes a column (501) and a bracket (502) for fixing the column (501) and the beam (401).

  In addition, when arranging the said raising / lowering body (10) in parallel, it is not necessary to make it a straight line, for example, when installing in the platform of the curved train, it is also possible to arrange according to the curvature of the said platform.

    Next, the operation | movement at the time of the shortening raise of the fence-shaped raising / lowering body apparatus (1) of Example 2 is demonstrated according to FIGS.

    When the motor (206) constituting the lifting / lowering body shortening / rising means (20) starts driving, the shaft of the motor (206) or the extension shaft that rotates in synchronization with the motor shaft starts to rotate clockwise, The vertical wire pulley (202) inserted in the shaft of the motor (206) or the extended shaft portion that rotates in synchronization with the motor shaft rotates clockwise.

  When the vertical wire pulley (202) rotates clockwise, the vertical wire (201) that vertically cuts the hollow portion of the elevating body (10) and connects the upper end to the vertical wire pulley (202) becomes the platform roof side (upper Direction).

  When the vertical wire (201) is pulled to the roof side (upward direction) of the platform, the second bottom surface (1041) in the lowermost cylinder (103) connected to the lower end of the vertical wire (201) and The top surface (1031) is pulled. When the top surface (1031) reaches the position of the lowermost cylinder lifting stopper (1034), the lowermost cylinder (103) is placed on the inner surface of the hollow portion of the intermediate cylinder F (102F), which is the intermediate cylinder immediately above. Along the platform (60) side of the platform along the roof side (upward).

  In addition, from the floor (60) side of the platform to the roof side (upward) along the hollow inner surface of the intermediate cylinder F (102F), which is the intermediate cylinder immediately above the lowermost cylinder (103). Ascending means that the position of the first bottom surface (1033) of the lowermost cylinder (103) rises from the floor (60) side of the platform to the roof side (upward). The overall length of the body (10) is shortened.

  The top surface (1031) position of the lowermost cylinder (103) that continues to rise from the floor (60) side of the platform along the hollow inner surface of the intermediate cylinder F (102F) to the roof side (upward), When the intermediate cylinder body F (102F) reaches the position of the intermediate cylinder lift stopper (1024), the intermediate cylinder body F (102F) is an intermediate cylinder body E that is the intermediate cylinder body immediately above. Ascending from the floor (60) side of the platform to the roof side (upward) along the hollow inner surface of (102E).

  When the operation as described above is repeated until the position of the uppermost cylinder raising stopper (1014) of the uppermost cylinder (101) is reached, the motor (206) stops.

  The state when the motor (206) is stopped is a part of FIG. 4 and FIG. 6 (the part where the lifting body is raised).

  Therefore, passengers waiting on the platform can get on the train.

  The shortening and raising operation time of the lifting body (10) is preferably faster than at least the current opening / closing time of the home fence. Although it is data published in magazines, according to the opinions of the station staff, the current opening and closing time of the platform fence is about 15 seconds per station. It is said that this has piled up and is affecting operation. Accordingly, considering the train operation, it is preferable that the shortening and raising operation time of the elevating body (10) is completed within at least 15 seconds.

  Next, the operation | movement at the time of the extension descent | fall of the fence-shaped raising / lowering body apparatus (1) of Example 2 is demonstrated according to FIGS.

  The motor (206) constituting the lifting / lowering body extension / lowering means (30) starts driving, and the shaft of the motor (206) or the extension shaft that rotates in synchronization with the motor shaft starts to rotate counterclockwise. The vertical wire pulley (202) inserted into the shaft of the motor (206) or the extended shaft portion that rotates in synchronization with the motor shaft rotates counterclockwise.

  When the vertical wire pulley (202) rotates counterclockwise, the vertical wire (201) that vertically cuts the hollow portion of the elevating body (10) and connects the upper end to the vertical wire pulley (202) becomes the platform floor (60). ) Move to the side (downward).

  When the vertical wire (201) moves toward the floor (60) side (downward) of the platform, the lowermost cylindrical body (103) and the lowermost cylindrical body ( 103) and the intermediate part cylinder A that has been pulled upward by the intermediate part cylinders B to F is lowered. The same operation is repeated up to the lowermost cylinder (103), and the lowermost cylinder (103) approaches the floor (60) side of the platform.

  Note that the fact that the lowermost cylinder (103) approaches the floor (60) side of the platform means that the position of the first bottom surface (1033) of the lowermost cylinder (103) is lowered. Therefore, the entire length of the lifting body (10) is extended.

  In addition, during the extended lowering operation of the lifting body (10), the lowering place obstacle detection sensor (1042) installed on the lower surface side of the first bottom surface (1033) is placed under a part of the lifting body (10). When it is detected that only the motor (206) corresponding to the descending place obstacle detection sensor (1042) is temporarily stopped. Only the motor (206) stops the operation, so that only the elevating body (10) corresponding to the motor (206) stops the extended lowering operation.

Thereafter, when the descending place obstacle detection sensor (1042) is no longer sensed, some motors (206) corresponding to the descending place obstacle detection sensor (1042) resume operation. When the motor (206) resumes operation, only the lifting body (10) corresponding to the motor (206) resumes the extended lowering operation.

  When the length of the elevating body (10) reaches a predetermined length (longest), a limit switch (not shown) installed on the vertical wire (201) is activated, and the motor (206) is stopped.

  The state when the motor (206) is stopped is a part of FIG. 6 (the part where the elevating body is lowered).

  Therefore, it is possible to prevent a passenger waiting on the platform from falling to the home.
