First Embodiment
A lift gate system 1 according to an embodiment of the present invention (hereinafter, referred to as "first embodiment") will be described below. Hereinafter, in the configuration and the operation of the lift type gate system 1, the description of the parts common to the lift type gate system 7 according to the above-mentioned prior art will be omitted. In addition, among components included in the lifting and lowering gate system 1, those corresponding to the components included in the lifting and lowering gate system 7 include “7” at the beginning of the code used in the lifting and lowering gate system 7. Use the replaced code.

  FIG. 1 is a front view of the lift gate system 1 in the passage blocking state, and FIG. 2 is a front view of the lift gate system 1 in the pass permission state. The lift gate system 1 includes an end lift gate 11T, an intermediate lift gate 11M, and a rope 12. Hereinafter, the end lift gate device 11T and the middle lift gate device 11M will be collectively referred to as lift gate device 11.

  The lift gate device 11 includes a main body 111 and a lift unit 112. Further, the lift type gate device 11 has a shielding plate 113 for shielding the opening 1111 provided on the upper surface of the casing of the main body 111 in the passage blocking state, and a passing person for the space above the opening 1111 in the passage permission state. A regulation plate 114 is provided which regulates the insertion of objects, arms and the like.

  FIG. 3 is a side view of the lift gate device 11 in the passage blocking state, and FIG. 4 is a side view of the lift gate device 11 in the passage permission status. The upper surface of the elevator unit 112 is shaped like a mountain so that a passerby does not put an object on the upper side in the closed state. The shielding plate 113 is a plate-like member having a mountain shape similar to the upper surface of the elevation unit 112, and the end side on the home 8 side is attached to the upper surface of the casing of the main body 111 by a hinge. The shield plate 113 is biased, for example, by a spring in the direction of the arrow shown in FIG.

  The restricting plate 114 is accommodated in the housing of the main body 111 in the passage blocking state. A hook 1141 is provided at the upper end of the regulating plate 114. Further, a hook 1121 is provided on the middle of the elevating part 112 in the vertical direction. The hook 1141 of the regulating plate 114 is hooked on the hook 1121 of the elevating part 112 while the elevating part 112 is lifted from the main body 111. Thereafter, the restricting plate 114 is pulled up with the rising of the elevation unit 112, and is moved to a position where the space between the opening 1111 and the rope 12 is partitioned from the space on the home 8 side as shown in FIG. As described above, since the space above the opening 1111 is partitioned from the space on the home 8 side by the restriction plate 114, the passerby can not inadvertently insert an object, an arm or the like between the main body 111 and the rope 12.

  When the elevating part 112 is lifted from the main body 111, the shielding plate 113 is pushed up by the upper surface of the regulating plate 114. As a result, in the passage permitted state, the shielding plate 113 is maintained in a state of being pressed against the front surface (the surface on the home 8 side) of the regulating plate 114.

  When the elevating part 112 is lowered, the regulating plate 114 is lowered together with the elevating part 112 by its own weight and accommodated in the casing of the main body 111. Further, along with the movement of the main body 111 of the restriction plate 114 into the housing, the shielding plate 113 is pivoted about the axis of the hinge by the urging of a spring or the like, and the opening 1111 is closed. When the bottom surface of the regulating plate 114 reaches the bottom surface or the like of the casing of the main body 111 while the elevating part 112 is lowered, the hook 1141 of the regulating plate 114 is disengaged from the hook 1121 of the elevating part 112.

  As described above, according to the lift type gate system 1, since the space between the opening 1111 of the main body 111 and the rope 12 is separated from the space on the home 8 side by the restriction plate 114 in the passage permitted state, There is no possibility that a person inadvertently inserts an object or an arm between the main body 111 and the rope 12. As a result, the risk of an object or a part of the body of a passerby being pinched between the main body 111 and the rope 12 is reduced.

  Further, according to the lift type gate system 1, the opening 1111 above the main body 111 is shielded by the shielding plate 113 in the passage blocking state, so that the risk of an object falling into the casing of the main body 111 is reduced.

A hook 2141 is provided at one end of the screen 2142 (the end not connected to the winding unit 2143). Further, hooks 2121 are provided in the elevating unit 212. While the elevating part 212 is lifted from the main body 211, the hook 2141 of the roll screen 214 is hooked on the hook 2121 of the elevating part 212. Thereafter, the screen 2142 unfolds while being fed out from the winding unit 2143 as the elevation unit 212 rises. As a result, as shown in FIG. 8, the space between the opening 2111 and the rope 22 is separated from the space on the home 8 side by the screen 2142 in the passage permitted state.

  The screen 2142 is taken up by the take-up unit 2143 as the elevating unit 212 descends. As a result, as shown in FIG. 7, the screen 2142 is accommodated in the housing of the main body 211 in the passage blocking state, and the opening 2111 is shielded by the shielding plate 213.

  The mechanism for taking up the screen 2142 as the winding unit 2143 raises the elevation unit 212 and winding the screen 2142 as the elevation unit 212 descends may be realized by, for example, a spring without special control. It may be realized by a motor or the like controlled in conjunction with the elevation of the elevation unit 212.

  As described above, according to the lift gate system 2, when the passage is permitted, the space between the opening 2111 of the main body 211 and the rope 22 is the home 8 side by the screen 2142 (an example of the sheet-like regulating member). Therefore, the passerby does not inadvertently put an object, an arm or the like between the main body 211 and the rope 22. As a result, the risk of an object or a part of the body of a passerby being pinched between the main body 211 and the rope 22 is reduced.

In addition, hooks 3121 are provided on the elevation unit 312. The hook 3141 of the bellows screen 314 is hooked on the hook 3121 of the elevator unit 312 while the elevator unit 312 is lifted from the main body 311. Thereafter, the bellows screen 314 is sequentially developed as the elevation unit 312 is raised. As a result, as shown in FIG. 12, the space between the opening 3111 and the rope 32 is separated from the space on the home 8 side by the bellows screen 314 in the passage permitted state.

  The opening 3111 is folded by its own weight while being bent along the fold along with the lowering of the raising and lowering part 312. As a result, as shown in FIG. 11, the bellows screen 314 is folded in the traffic blocking state. Further, the opening 3111 is shielded by the shielding plate 313 in the passage blocking state.

  As described above, according to the lift gate system 3, when the passage is permitted, the space between the opening 3111 of the main body 311 and the rope 32 is the home 8 by the bellows screen 314 (an example of the sheet-like regulating member). Since the space is separated from the space on the side, a passerby can not inadvertently put an object, an arm or the like between the main body 311 and the rope 32. As a result, the risk of an object or a part of the body of a passerby being pinched between the main body 311 and the rope 32 is reduced.
