  Some gate devices that permit and prohibit the passage of passersby by opening and closing the doors are in contact with the ends of the other doors, pillars, and the like in which the ends of the closed doors are paired. When a gate device of a type in which the end of the door is in contact with another member (hereinafter referred to as “contacted member”) is used in a cold region, if the closed state continues for a long time, The end part and the contacted member are fixed by ice, and there is a problem that the door cannot be opened.

  In view of the above background, an object of the present invention is to reduce open / close failure due to ice when a gate device of a type in which an end portion of a door in a closed state comes into contact with a contacted member is used in a cold region. .

In order to solve the above-described problems, the present invention includes a door that opens and closes, and a contacted member that contacts an end of the door, and the end and the contacted member reduce sticking due to ice. as the door to provide a gate device having one or more point-like and one or more linear at least one in contact with each other shape when in the closed state, as a first aspect.

  According to the gate device of the first aspect, compared to the conventional technique in which the end of the door and the contacted member come into contact with each other in the closed state, the area of contact between the end of the door and the contacted member Therefore, it is difficult for ice to stick, and the door opening / closing failure is reduced.

  In the gate device according to the first aspect described above, a configuration in which the end portion has one or more conical protrusions facing the contacted member may be employed as the second aspect.

  In the gate device according to the first or second aspect described above, a configuration in which the contacted member has one or more conical protrusions toward the end is adopted as a third aspect. Also good.

  According to the gate device of the second or third aspect, since the contact portion by the point is substantially realized when the end portion of the door or the projecting portion of the contacted member is in the closed state, it is difficult to be fixed by ice. Failure to open and close the door is reduced.

  In any one of the first to third gate devices described above, a configuration in which the end portion has one or more hook-shaped protrusions facing the contacted member may be adopted as a fourth aspect. Good.

  Further, in any one of the first to fourth gate devices described above, a configuration in which the contacted member has one or more hook-shaped protrusions facing the end portion is employed as a fifth aspect. May be.

  According to the gate device of the fourth or fifth aspect, since the contact portion by the line is substantially realized when the protrusion of the door end portion or the contacted member is in the closed state, the fixing due to ice hardly occurs. Failure to open and close the door is reduced.

  In any one of the first to fifth gate devices described above, when the door is in a closed state, the end portion and the contacted member have a portion that overlaps in the normal direction of the door. It may be adopted as the sixth aspect.

  According to the gate device of the sixth aspect, when an external force due to wind or the like is applied in the normal direction of the door when the door is in the closed state, the abutted member supports the end of the door against the external force. Therefore, the inconvenience that the door that should be in a closed state opens is unlikely to occur.

[Embodiment]
A gate device 1 according to an embodiment of the present invention will be described below. FIG. 1 is a diagram showing the overall configuration of the gate device 1. FIG. 1 illustrates a case where the gate device 1 is installed at the platform of a railway station. The installation location of the gate device 1 may be any location as long as it is necessary to permit and prohibit the passage of passers-by.

  In FIG. 1, the gate device 1 is composed of a left side device 1L and a right side device 1R. The left side device 1L includes a main body 11L and a door 12L. The right side device 1R includes a main body 11R and a door 12R. Hereinafter, when the main body 11L and the main body 11R are not distinguished from each other, they are referred to as the main body 11. Further, when the door 12L and the door 12R are not distinguished from each other, they are referred to as the door 12.

  The main body 11 is disposed in the vicinity of the edge of the platform 8 on the track side, and serves as a protective wall that protects the user of the train 9 from falling from the platform 8 to the track. The main body 11 includes a moving mechanism that reciprocates the door 12 in the horizontal direction. The main body 11 accommodates the door 12 by a moving mechanism and permits the user to travel between the platform 8 and the train 9, and the user 11 between the platform 8 and the train 9 projects the door 12. It is possible to switch between a closed state in which traffic is prohibited. The left side device 1L and the right side device 1R work together to move the door 12L or the door 12R, thereby creating an open state or a closed state. FIG. 1 shows the gate device 1 in a state where it is in the process of shifting from the closed state to the open state.

  The front end (right direction in FIG. 1) in the protruding direction of the door 12L is configured by a door tip member 121L. Similarly, the front end (left direction in FIG. 1) in the protruding direction of the door 12R is configured by a door tip member 121R. Hereinafter, when the door-end member 121L and the door-end member 121R are not distinguished from each other, they are referred to as the door-end member 121. The door end member 121 is a member in which an elastic body such as rubber is formed, and is attached to a front edge portion in the protruding direction of the main body of the door 12.

  FIG. 2 shows the gate device 1 in the closed state. In the closed state, the door-end member 121L and the door-end member 121R are in contact with each other. That is, the door tip member 121L is a contacted member that contacts the door tip member 121R, and the door tip member 121R is a contacted member that contacts the door tip member 121L.

  When the gate device 1 is arranged in a cold region and the frequency of the train visiting the station is low, the state where the door-end member 121L and the door-end member 121R are in contact with each other continues for a long time, and the door-end member 121L and the door-end The member 121R may be fixed with ice. In particular, when the gate device 1 is disposed outdoors, the door-end member 121L and the door-end member 121R are likely to stick due to ice. Therefore, the door-end member 121L and the door-end member 121R have a shape that is less likely to be fixed by ice as compared to the door-end member according to the related art.

  FIG. 15 is a diagram illustrating the shapes of the door-end member 921L and the door-end member 921R according to the related art. The door-end member 921L is a member corresponding to the door-end member 121L according to the present embodiment, and the door-end member 921R is a member corresponding to the door-end member 121R according to the present embodiment. FIG. 15A is a front view of the door tip member 921L and the door tip member 921R in transition between the open state and the closed state. FIG. 15B is a front view of the door-end member 921L and the door-end member 921R in the closed state. FIG. 15C is a top view of the door tip member 921L and the door tip member 921R that are in transition between the open state and the closed state. FIG. 15D is a top view of the door-end member 921L and the door-end member 921R in the closed state. FIG. 15E is a side view of the door tip member 921L and the door tip member 921R.

  In FIG. 15E, the hatched region is a region where the door tip member 921L and the door tip member 921R are in contact with each other in the closed state (hereinafter referred to as “contact region”). As shown in FIG. 15E, the door tip member 921L and the door tip member 921R are in contact with each other in the closed state, so that the area of the contact area is large. Therefore, when ice adheres to the contact area, the door-end member 921L and the door-end member 921R are strongly fixed by the attached ice. As a result, the inconvenience that the door cannot be opened tends to occur.

  FIG. 3 is a diagram illustrating the shapes of the door-end member 121L and the door-end member 121R according to the present embodiment. 3A to 3E are the same as those in FIGS. 15A to 15E. This also applies to FIGS. 4 to 11.

  As shown in FIG. 3, a plurality of conical projections are arranged on the side surface where the door tip member 121L contacts the door tip member 121R. Similarly, a plurality of conical protrusions are also arranged on the side surface where the door tip member 121R contacts the door tip member 121L.

  The protrusions of the door end member 121L and the protrusions of the door end member 121R are arranged at positions where the protrusions do not collide with each other in the closed state. Therefore, each of the protrusions of the door tip member 121L comes into contact with the flat portion of the side surface of the door tip member 121R at a point. Similarly, each of the protrusions of the door-end member 121R comes into contact with the flat portion of the side surface of the door-end member 121L substantially at a point. In addition, in FIG.3 (e), the some point shown along with the vertical direction on the left side of the side surface of the door-end member 121L and the door-end member 121R has shown the contact | abutting area | region.

  As shown in FIG. 3 (e), the door tip member 121L and the door tip member 121R are substantially in contact with each other at a point in the closed state, so that the area of the contact region is the door tip member 921L and the door tip member according to the prior art. It is narrower than the area of the contact area of 921R. Therefore, even if ice adheres to the contact area, the force with which the door-end member 121L and the door-end member 121R are fixed by the adhering ice is weak. Therefore, the inconvenience that the door 12 cannot be opened is unlikely to occur.

  As described above, according to the gate device 1, even when used in a cold region, the door 12 is unlikely to open and close. Since the gate device 1 does not require a heater or the like, the gate device 1 is realized at low cost and has high durability.

[Modification]
The embodiment described above can be variously modified. Examples of these modifications are shown below. Note that the above-described embodiment and the modifications described below may be combined as appropriate.

(1) Arrangement | positioning and the number of the protrusions which the door-end member 121 has are not restricted to what is illustrated to embodiment mentioned above. FIG. 4 is a diagram illustrating the door-end member 121 having protrusions having an arrangement different from the arrangement of the protrusions included in the exemplary door-end member 121 in the embodiment described above. The door-end member 121L and the door-end member 121R having the protrusions arranged as illustrated in FIG. 4 also contact each other substantially at a point in the closed state, so that the inconvenience that the door 12 cannot be opened is less likely to occur.

(2) The cross-sectional shape of the door-shaped member 121 having a weight-shaped projection cut by a plane perpendicular to the projection direction is not limited to a circle. For example, the door end member 121 may have a quadrangular pyramid-shaped protrusion.

(3) The door-end member 121 may have a protrusion that is not of a weight shape. FIG. 5 is a diagram illustrating a door-end member 121 having a quadrangular prism-shaped protrusion. In FIG. 5E, the hatched area is the contact area. According to the door-end member 121 having the protrusions illustrated in FIG. 5, the door-end member 121L and the door-end member 121R are in contact with each other in a plurality of small rectangular areas in the closed state. Therefore, the area of the contact area is large compared to the case of the door-end member 121 having the protrusions illustrated in FIGS. 3 and 4, and the door-end member 121L and the door-end member 121R are likely to be fixed by ice. The area of the contact area is small compared to the case of the door tip member 921L and the door tip member 921R according to the prior art illustrated in FIG. Therefore, compared with the prior art, the inconvenience that the door 12 cannot be opened is less likely to occur.

(4) The door end member 121 may have a hook-shaped protrusion. FIG. 6 illustrates the door-end member 121 having a hook-shaped protrusion having the horizontal direction as the longitudinal direction. FIG. 7 exemplifies a door-end member 121 having a hook-shaped protrusion having a vertical direction as a longitudinal direction. FIG. 8 illustrates a door-end member 121 having a hook-shaped projection having a longitudinal direction as an oblique direction with respect to a horizontal direction or a vertical direction. FIG. 9 illustrates the door-end member 121 having a serpentine hook-shaped protrusion. In addition, the shape of the cross section at the time of cut | disconnecting the projection part which the door-end member 121 illustrated in FIGS. 6-9 has in a surface perpendicular | vertical to a longitudinal direction is a triangle, for example. The broken lines in FIGS. 6 (e), 7 (e), 8 (e), and 9 (e) indicate contact areas. According to the door-end member 121 having the hook-shaped protrusions illustrated in FIGS. 6 to 9, the door-end member 121 </ b> L and the door-end member 121 </ b> R are substantially in contact with each other in a closed state. Inconvenience is unlikely to occur.

(5) The shape of the door-end member 121 illustrated in FIGS. 3 to 9 is a shape having a flat side surface and a protrusion on the side surface. The shape of the door-end member 121 may not have a flat side surface. FIG. 10 is a diagram illustrating the shape of the door-end member 121 that does not have a flat side surface. The door-end member 121L and the door-end member 121R illustrated in FIG. 10 have shapes that are greatly different from each other. Specifically, the door-end member 121L has a shape in which the side surface is undulated as a whole, and the door-end member 121R has a completely flat shape in which the side surface does not have a protrusion. In this case, the top of the wave of the door-end member 121L corresponds to a hook-shaped protrusion, and abuts on the flat side surface of the door-end member 121R. A broken line shown in FIG. 10E is the contact area. Also with the door-end member 121 illustrated in FIG. 10, the door-end member 121L and the door-end member 121R are substantially in contact with each other in a closed state, so that the inconvenience that the door 12 cannot be opened is less likely to occur.

(6) The door-end member 121L and the door-end member 121R may have a shape having an overlapping portion in the normal direction of the door 12 in the closed state. FIG. 11 and FIG. 12 are views illustrating the door member 121L and the door member 121R having such shapes. In the closed state, the door tip member 121L and the door tip member 121R are overlapped in the normal direction X or the normal direction X ′ of the door 12 in the range D shown in FIG. 11 (d) or FIG. 12 (d). . Therefore, for example, when an external force is applied in the normal direction of the door 12 due to the passage of a train or the like, the door-end member 121L and the door-end member 121R catch each other in the range D to resist the external force, and the door 12L and the door Warpage in the normal direction X or normal direction X ′ of 12R is reduced.

(7) In embodiment mentioned above, the gate apparatus 1 is comprised by the left side apparatus 1L and the right side apparatus 1R, and the door tip member 121R which comprises the door end member 121L which comprises the edge part of the door 12L, and the edge part of the door 12R. Abut each other. Instead, a configuration in which the gate device 1 does not include either the left device 1L or the right device 1R may be employed.

  FIG. 13 is a diagram illustrating a gate device 2 according to a modified example that does not have the right side device 1R. The gate device 2 includes a protective wall 2R instead of the right device 1R included in the gate device 1. In the gate device 2, the door end member 121L abuts against the side surface of the protective wall 2R in the closed state. That is, the contacted member of the door end member 121L is a side surface portion of the protective wall 2R.

  In this case, the door tip member 121L has the shape of the door tip member 121L illustrated in FIGS. 3 to 11, for example, and the side surface portion of the protective wall 2R has the shape of the door tip member 121R illustrated in FIGS. Configured to have. As a result, the area of the contact area between the door end member 121L and the protective wall 2R is reduced, and the inconvenience that the door 12L cannot be opened is less likely to occur.

(8) In the embodiment described above, switching between the closed state and the open state is performed by sliding the door 12 in the horizontal direction. The direction in which the door 12 moves for switching between the closed state and the open state is not limited to the horizontal direction.

  FIG. 14 is a diagram (top view) illustrating a gate device 3 according to a modification of the configuration in which the door 12 rotates about a vertical axis. Also in the gate apparatus 3, the door-end member 121L and the door-end member 121R are comprised so that it may have a shape illustrated in FIGS. As a result, the area of the contact area between the door-end member 121L and the door-end member 121R becomes narrow, and the inconvenience that the door 12 cannot be opened is less likely to occur.
