Description

[Technical Field]

[0001] The present invention relates to a platform gate that is closed by protruding a pair of door bodies between a pair of main body ends. [Background technology]

[0002] A known movable platform fence is one that comprises a door pocket and a movable door, as well as a first support guide section with a biasing roller that contacts the upper part of the movable door, and a second support guide section with a load support roller that contacts the lower part of the movable door, and the second support guide section has a roller position adjustment cam section that supports the roller support section with a rotating cam that makes it possible to adjust the fixed angle relative to the door pocket (Patent Document 1).

[0003] Another type of movable platform fence is known, which has a door body that moves back and forth relative to a fixed part, and the door body is freely swingable around a swing axis parallel to the axis of movement of the door body. A swing control piece that abuts against the door body and restricts its swing is attached to the fixed part via a position adjustment means such as a long hole or bolt that adjusts the attachment position (Patent Document 2).

[0004] The movable platform gates described above are based on the premise that adjustments are made by tinkering with the internal components of the device, which means there are limitations on the adjustment values ​​that can be made during assembly and the risk of increased load on the drive components.In addition, since the installers are not experts in product assembly, there are cases where they cannot intervene in door adjustments, which requires the manufacturer to dispatch an engineer or assembler.

[0006] The present invention has been made in consideration of the above-mentioned background art, and aims to provide a platform fence that reduces the need to adjust parts inside the door pocket or fence body when installing the platform fence.

[0007] In order to achieve the above-mentioned object, the platform fence of the present invention comprises a first door body that advances and retreats laterally from the end of the first platform fence body and has a first abutment member at its tip, a second door body that advances and retreats laterally from the end of the second platform fence body and has a second abutment member at its tip that abuts against the first abutment member in the closed state, and an adjustment mechanism provided on at least one of the first door body or the second door body that adjusts the position of one or a combination of the first abutment member and the second abutment member in two directions perpendicular to the opening and closing direction.

[0008] According to the above-mentioned platform gate, an adjustment mechanism provided on the door body adjusts the position of one or a combination of the first and second abutment members in two directions perpendicular to the opening and closing direction, so that after the platform gate is installed, it is possible to align the first and second door bodies in two directions perpendicular to the opening and closing direction. As a result of being able to adjust the positions in two directions perpendicular to the opening and closing direction, it is also possible to adjust the rotation angle around the opening and closing direction.

[Figure 8] FIG. 10 is an oblique view illustrating a door body in a modified platform fence. DETAILED DESCRIPTION OF THE INVENTION

[0010] First, the overall structure of a platform fence according to one embodiment of the present invention will be described with reference to Figure 1. Figure 1 is a view of the platform fence 100 as seen from the platform PF side, showing the state in which the exterior panel on the platform PF side of the platform fence 100 has been removed. In this specification, the platform PF side of the platform fence 100 is considered to be the back side of the platform fence 100.

[0011] The platform fence 100 separates the station platform PF from the track RL. The platform fence 100 is also called a movable platform fence. The platform fence 100 is made up of a predetermined number of platform fence elements 10 lined up in a row to cover a predetermined area of ​​the platform PF. Each platform fence element 10 has a door body 20 and a platform fence main body 30. In the example of Figure 1, in each platform fence element 10, a pair of door bodies 20 protrude from the end opening of the platform fence main body 30, and the door bodies 20 close the boarding and alighting passageway, thereby forming a fence-like device that extends along the edge of the platform PF and opens and closes at appropriate positions.

[0012] The door body 20 is a door element that is housed within the platform fence main body 30 and is provided so that it can be freely inserted and removed. The door body 20 has a main door body 21 that moves laterally forward and backward from a first end 32, which is one end of the platform fence main body 30, and a secondary door body 22 that moves laterally forward and backward from a second end 33, which is the other end of the platform fence main body 30. Normally, the operations of the main door body 21 and the secondary door body 22 are controlled so that they open and close in conjunction with each other.

[0013] The platform fence main body 30 is fixed to the floor of the platform PF and has a door pocket structure that holds the door body 20 so that it can move back and forth. The platform fence main body 30 has an electric circuit system 40 and the like inside a housing 31.

[0014] A guide mechanism 50 and a transmission mechanism 60 are provided between the door body 20 and the platform fence main body 30.

[0015] In Figure 1, the platform fence element 10 on the right side is referred to as the first platform fence element 10A, and the platform fence element 10 on the left side is referred to as the second platform fence element 10B. The first platform fence element 10A has a first platform fence main body 30A and a first door body 20A that moves from the end of the first platform fence main body 30A (first end 32 on the left side in the figure) to the side where the second platform fence element 10B is located. The second platform fence element 10B has a second platform fence main body 30B and a second door body 20B that moves from the end of the second platform fence main body 30B (second end 33 on the right side in the figure) to the side where the first platform fence element 10A is located. When considering opening and closing, the first door body 20A and the second door body 20B work together to function like sliding doors that open and close in sync. In Fig. 1, solid lines indicate door bodies 20A, 20B that are abutting against each other and in a closed state, and dashed lines indicate door bodies 20A, 20B that are spaced apart and in an open state. The first platform fence main body 30A and the second platform fence main body 30B are both platform fence main bodies 30 and are arranged adjacent to each other. The first door body 20A is the main door body 21 of the first platform fence main body 30A, and the second door body 20B is the secondary door body 22 of the second platform fence main body 30B.

[0016] The relationship between the first platform fence element 10A and the second platform fence element 10B as described above holds true between any pair of adjacent platform fence elements 10.

[0017] In each platform fence body 30, the electrical circuit system 40 is a component used to control and drive the platform fence elements 10, and enables the electrically operated opening and closing of the door body 20. The electrical circuit system 40 includes a control device 41, a driving force generating device 44, etc.

[0018] Of the electrical circuit system 40, the control device 41, driving force generating device 44, etc. are arranged on a circuit board (not shown) and fixed to the housing 31. The electrical circuit system 40 provided in the series of platform fence elements 10 is connected via a communication line CC to a general control device 107 that is separately provided on the platform PF or its periphery. The control device 41 includes a computer, receives opening / closing signals, etc. from the general control device 107, and controls the operation of the platform fence elements 10. The driving force generating device 44 generates a driving force to move the door body 20. The driving force generating device 44 has a first motor 44a that drives the main door body 21 and a second motor 44b that drives the secondary door body 22.

[0019] The guide mechanism 50 has, for example, a guide rail 51 provided on the housing 31 side and a sliding member 52 attached to the door body 20. The sliding member 52 includes a roller, an adjustment jig, etc., and is relatively movable along the guide rail 51, allowing the door body 20 to move in the ±X directions relative to the housing 31, i.e., to move laterally. The guide rail 51 and the sliding member 52 are provided corresponding to the upper and lower parts of the door body 20, respectively, and allow the door body 20 to move smoothly laterally, i.e., to open and close smoothly. A mechanism for adjusting the attitude of the door body 20 relative to the housing 31 can be incorporated into the sliding member 52.

[0020] The guide mechanism 50 may be configured such that the sliding member 52 is fixed to the housing 31 and the guide rail 51 is fixed to the door body 20 .

[0021] The transmission mechanism 60 has an open-end type timing belt 61 that is fixed at one end to the door body 20 and at the other end to the housing 31, and a plurality of pulleys 62 around which the timing belt 61 is wound. Motors 44a and 44b are connected to specific pulleys 62.

[0022] FIG. 2(A) is a front view illustrating the platform fence 100 in an open state, and FIG. 2(B) is a front view illustrating the platform fence 100 in a closed state. The multiple platform fence elements 10 that make up the platform fence 100 are sequentially installed on the platform PF and positioned in advance. However, it is not easy to accurately align the leading edge 81 of the first door body 20A, which is advanced in direction A from the first platform fence main body 30A, with the leading edge 82 of the second door body 20B, which is advanced in direction B from the second platform fence main body 30B, to within millimeters. Therefore, when precise installation is required, the workability of construction decreases. Therefore, in the illustrated platform fence 100, adjustment mechanisms 91 and 92 are provided in conjunction with the first abutment member 83 provided at the leading edge 81 of the first door body 20A and the second abutment member 84 provided at the leading edge 82 of the second door body 20B. One or both of the adjustment mechanisms 91, 92 adjust the position of one or a combination of the first abutment member 83 and the second abutment member 84 in two directions perpendicular to the ±X directions, i.e., the Y direction and the Z direction, which are the opening and closing direction D0. This allows the first abutment member 83 at the leading edge 81 of the first door body 20A and the second abutment member 84 at the leading edge 82 of the second door body 20B to be positioned relative to the door bodies 25a, 25b after installation, even if the installation precision of the platform fence bodies 30A, 30B is not very high. By adjusting the positions of these members relative to the door bodies 25a, 25b, the leading edge 81 of the first door body 20A and the leading edge 82 of the second door body 20B can be aligned with each other and abutted against each other to achieve an appropriate closed state. In this case, the abutment members 83, 84 are easily accessible from the outside and can be installed freely, so there is no need to adjust the position of the door bodies 25a, 25b of the door bodies 20 themselves.

[0023] FIG. 3(A) is a perspective view illustrating the tip 82 of the second door body 20B, and FIG. 3(B) is a perspective view illustrating the tip 81 of the first door body 20A.

[0024] Referring to FIG. 3(B), a first abutment member 83 made of rubber or other elastic material and elongated in the vertical Z direction is fixed to an end surface 81e of a plate member 81a constituting the tip 81 of the first door body 20A. The plate member 81a corresponds to the door main body 25a of the first door body 20A excluding the first abutment member 83. The first abutment member 83 extends along and covers the end surface 81e. However, the width of the first abutment member 83 is narrow, approximately half the width of the plate member 81a, and the vertical dimension of the first abutment member 83 is slightly narrower than the vertical dimension of the plate member 81a. The first abutment member 83 is fixed to the plate member 81a at four locations with fasteners 91a. The first abutment member 83 can be displaced or shifted in the Y direction or the Z direction by loosening a fastener 91a that is part of the adjustment mechanism 91, and is re-fixed to the plate member 81a in the displaced state by tightening the fastener 91a at the desired position. A recessed groove 91g that extends vertically along the entire first abutment member 83 is formed, and the recessed groove 91g functions as the adjustment mechanism 91, as will be described in detail later. The recessed groove 91g has a stepped shape in a cross section in the XY direction perpendicular to the up-down direction D2, and more specifically, is a tapered groove that widens on the open side.

[0025] Referring to FIG. 3(A), a second abutment member 84 made of rubber or other elastic material and elongated in the vertical Z direction is fixed to an end surface 82e of a plate member 82a constituting the tip 82 of the second door body 20B. The plate member 82a corresponds to the door main body 25b of the second door body 20B excluding the second abutment member 84. The second abutment member 84 extends along and covers the end surface 82e. However, the width of the second abutment member 84 is narrow, approximately half the width of the plate member 82a, and the vertical dimension of the second abutment member 84 is slightly narrower than the vertical dimension of the plate member 82a. The second abutment member 84 is fixed to the plate member 82a at four locations with fasteners 92a. The second abutment member 84 can be displaced or shifted in the Y direction or the Z direction by loosening a fastener 92a that is part of the adjustment mechanism 92, and is re-fixed to the plate member 82a in the displaced state by tightening the fastener 92a at the desired position. A convex rib 91h extending vertically along the entire second abutment member 84 is formed, and the convex rib 91h is capable of fitting into a concave groove 91g of the first abutment member 83, as will be described in detail later, and functions as the adjustment mechanism 92. The convex rib 91h is arc-shaped, more specifically, semicircular, in a cross section taken along the XY direction perpendicular to the up-down direction D2, and is rotatable around an axis parallel to the up-down direction D2 while in contact with or close to the first abutment member 83.

[0026] FIG. 4(A) is a partially enlarged perspective view of the leading end 81 of the first door body 20A, and FIG. 4(B) is a partially exploded perspective view of the leading end 81 of the first door body 20A or the door main body 25a. A nut 91b of the fastener 91a is screwed into an elongated hole 91c of the first abutting member 83 so as to be embedded therein. The elongated hole 91c is provided in the first abutting member 83 and extends in the front-to-rear direction D1. The nut 91b is screwed onto a screw 91n extending in the +X direction, i.e., the leading end direction, from a movable member 91m that moves along a slotted track 91s formed so as to be embedded in the leading end 81 of the plate member 81a. The slotted track 91s is provided in the door main body 25a of the first door 20A and extends in the up-down direction D2. A seat portion 91k of the elongated hole 91c is sandwiched between the nut 91b and the movable member 91m, thereby detachably fixing the first abutting member 83. In the above, the nut 91b and the movable member 91m constitute the fastener 91a. The combination of the slot track 91s, the elongated hole 91c, and the fastener 91a is called the adjustment mechanism 91, and the recessed groove 91g of the first abutment member 83 also functions as the adjustment mechanism 91 from a different perspective than the fastener 91a, etc.

[0027] The first abutment member 83 can be appropriately displaced in the front-rear direction D1 relative to the tip 81 of the first door body 20A or the door main body 25a depending mainly on the length of the elongated hole 91c of the adjustment mechanism 91. Here, the front-rear direction D1 is a direction perpendicular to the door main bodies 25a, 25b of the first door body 20A or the second door body 20B and corresponds to the ±Y direction. Furthermore, depending on factors such as the length of the first abutment member 83 and the length of the slot track 91s, the first abutment member 83 can be appropriately displaced in the up-down direction D2 relative to the tip 81 of the first door body 20A or the door main body 25a. Here, the up-down direction D2 is a direction along the tip of the door main bodies 25a, 25b of the first door body 20A or the second door body 20B and corresponds to the ±Z direction. By utilizing the above displacements in combination, the first contact member 83 can be fixed in a position where it is slightly rotated within a range of a predetermined tilt angle ±Δβ (corresponding to the rotation angle β shown in FIG. 3(B)) around the opening / closing direction D0, i.e., the Y axis, relative to the tip 81 of the first door body 20A or the door main body 25a, by the adjustment mechanism 91. Here, the tilt angle ±Δβ of the first contact member 83 is determined by the length and spacing of the elongated holes 91c formed at the upper and lower ends of the first contact member 83.

[0028] Returning to FIG. 3, the adjustment mechanism 92 for the tip 82 of the second door body 20B has a structure similar to that of the adjustment mechanism 91 for the tip 81 of the first door body 20A. That is, the adjustment mechanism 92 has a fastener 92a and components equivalent to the slot track 91s and elongated hole 91c shown in FIGS. 4(A) and 4(B). The fastener 92a includes components equivalent to the screw 91n shown in FIG. 4(B) and a nut 92b that screws into the screw. This allows the second abutment member 84 to be displaced in the horizontal Y direction, i.e., the up-down direction D2, relative to the tip 82 of the second door body 20B or the door main body 25b, and the second abutment member 84 to be displaced in the vertical Z direction, i.e., the front-rear direction D1, relative to the tip 82 of the second door body 20B or the door main body 25b. In relation to the above displacement, the adjustment mechanism 92 can fix the second abutment member 84 in a position where it is slightly rotated within a predetermined tilt angle ±Δβ (corresponding to the rotation angle β) around the opening / closing direction D0, i.e., the Y axis, relative to the tip 82 of the second door body 20B or the door body 25b. The adjustment mechanism 92 has a protrusion 91h provided on the second abutment member 84 that corresponds to the recessed groove 91g of the adjustment mechanism 91. The recessed groove 91g of the adjustment mechanism 91 and the protrusion 91h of the second abutment member 84 fit together when the first door body 20A and the second door body 20B are in the closed state.

[0029] 5(A) is a plan view showing the relative positions of the first door body 20A and the second door body 20B when they are closed, and the positional relationship between the first door body 20A and the second door body 20B and the contact members 83 and 84. The recessed groove 91g of the first contact member 83, which is an element of the adjustment mechanism 91, and the protruding rib 91h of the second contact member 84, which is an element of the adjustment mechanism 92, are arranged to fit together.

[0030] FIG. 5B shows a case where the first door body 20A and the second door body 20B are misaligned in the front-to-rear direction. When there is such a misalignment, the adjustment mechanism 91 is used to shift the first abutment member 83 by ε1 in the -Y direction from its original position indicated by the dashed-dotted line, and the adjustment mechanism 92 is used to shift the second abutment member 84 by ε2 in the +Y direction from its original position indicated by the dashed-dotted line. The first abutment member 83 and the second abutment member 84 are positioned opposite each other and positioned in the Y direction. In other words, the edges of the first door body 20A and the second door body 20B are aligned, achieving a proper closed state. The shift amounts ε1 and ε2 can be set to allow for a tolerance of, for example, approximately ±4 mm.

[0031] 5(C) shows a case where the first door body 20A and the second door body 20B are not parallel but form an angle. In this case, the recessed groove 91g of the adjustment mechanism 91 and the protruding rib 91h of the adjustment mechanism 92 are fitted together. The recessed groove 91g is a tapered groove that widens on the open side and is relatively shallow, allowing the protruding rib 91h to rotate around the Z axis parallel to the up-down direction D2 or around the vertical axis. This allows the tip 81 of the first door body 20A or the door body 25a to rotate slightly relative to the tip 82 of the second door body 20B or the door body 25b within a predetermined tilt angle ±Δα (corresponding to the rotation angle α). In other words, the first door body 20A and the second door body 20B do not need to be completely parallel in the closed state, and even if a relative angle is formed between the two door bodies 20A and 20B, the tip 81 of the first door body 20A and the tip 82 of the second door body 20B can be butted together to achieve an appropriate closed state. In other words, even if the first door body 20A and the second door body 20B are not parallel but form an angle, the door edges of the first door body 20A and the second door body 20B can be aligned.

[0032] Referring to FIG. 6, a case where the door body 25a of the first door body 20A and the door body 25b of the second door body 20B are misaligned in the vertical Z direction will be described. When such a misalignment occurs, one or both of the first abutment member 83 and the second abutment member 84 are shifted in the ±Z direction or the vertical direction D2 by a shift amount φ1. Although the misalignment of the door bodies 25a and 25b remains, the first abutment member 83 and the second abutment member 84 are positioned facing each other without any misalignment. In other words, the leading edges of the first door body 20A and the second door body 20B are aligned, achieving a proper closed state. The shift amount φ1 can be set to allow for, for example, approximately 10 mm.

[0033] 7, let us consider a state in which the door body 25a of the first door body 20A is tilted by a slight rotation about the front-to-rear Y axis, and a state in which the door body 25b of the second door body 20B is tilted by a slight rotation about the front-to-rear Y axis. In this case, an in-plane tilt occurs in which the first door body 20A and the second door body 20B are tilted so that they are higher or lower at the center where they meet. This in-plane tilt occurs when the first platform fence body 30A and the second platform fence body 30B are mounted at an angle by a slight rotation about the Y axis, or when the door bodies 20A and 20B are mounted at an angle by a slight rotation about the Y axis relative to the platform fence bodies 30A and 30B. 5(A), even in such a case, since the recessed groove 91g of the first abutting member 83 has a depth d of about several millimeters, even if the bottom surface 95a of the recessed groove 91g of the first abutting member 83 and the top surface 95b of the ridge 91h of the second abutting member 84 are spaced apart at their upper ends in both doors 20A and 20B in the closed state with both abutting members 83 and 84, as long as the distance e is about several millimeters and is less than the depth d of the recessed groove 91g, the door bodies 20A and 20B or the abutting members 83 and 84 will appear to be connected without a break when viewed from the front, that is, when both doors 20A and 20B are viewed in the +Y direction. This allows the first door body 20A and the second door body 20B to tilt within a predetermined tilt angle ±Δγ (corresponding to the rotation angle γ) due to relative rotation around the Y axis. Furthermore, even if tilting of the first door body 20A and the second door body 20B around the Y axis is permitted, if the door bodies 20A, 20B or the abutment members 83, 84 are connected without interruption when viewed from the +Y direction, when something like a thin rod is caught between the first abutment member 83 and the second abutment member 84, such incomplete locking can be detected with sufficient accuracy by monitoring the position of the door bodies 20A, 20.

[0034] The platform fence 100 according to the above embodiment comprises a first door body 20A which advances and retreats laterally from the end 32 of the first platform fence main body 30A and has a first abutment member 83 at its tip 81, a second door body 20B which advances and retreats laterally from the end 33 of the second platform fence main body and has a second abutment member 84 at its tip 82 which abuts against the first abutment member 83 in the closed state, and adjustment mechanisms 91, 92 which are provided on at least one of the first door body 20A or the second door body 20B and which adjust the position of one or a combination of the first abutment member 83 and the second abutment member 84 in two directions D1, D2 perpendicular to the opening and closing direction D0.

[0035] According to the platform fence 100, the adjustment mechanisms 91, 92 provided on the door bodies 20A, 20B adjust the position of one or a combination of the first abutment member 83 and the second abutment member 84 in two directions perpendicular to the opening and closing direction D0, so that after the platform fence 100 is installed, it is possible to align the first door body 20A and the second door body 20B in the two directions D1, D2 perpendicular to the opening and closing direction D0. As a result of being able to adjust the position in two directions perpendicular to the opening and closing direction D0, it is also possible to adjust the rotation angle β around the opening and closing direction D0.

[0036] Furthermore, in the platform fence 100 of the above embodiment, the slot tracks 91s provided on the door bodies 25a, 25b and the multiple long holes 91c provided on the abutment members 83, 84 enable position adjustment within a relatively large allowable dimensional range, and the fastening devices 91a, 92a ensure stable fixation of the abutment members 83, 84.

[0037] 〔others〕 The present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit and scope of the present invention.

[0038] It is possible to omit one of the adjustment mechanisms 91, 92. For example, if the adjustment mechanism 92 is omitted, the second abutment member 84 is fixed to the door body 25b, but the first abutment member 83 is displaced with respect to the door body 25a, so that the first abutment member 83 and the second abutment member 84 can be disposed opposite each other. Note that, if the adjustment mechanism 92 is omitted, as shown in FIG. 8, a circular hole 192c is formed in the second abutment member 84 instead of the elongated hole 92c, and the components corresponding to the slot track 91s and the movable member 91m shown in FIG. 4 are omitted from the tip 82 of the second door body 20B, and instead, a fastener 192a corresponding to a screw 91n (see FIG. 4) protrudes from the end face 82e, onto which a nut 92b is screwed.

[0039] The adjustment mechanisms 91 and 92 are not limited to those using the elongated holes 91c or the slotted tracks 91s, but may be mechanisms that allow for various types of positional deviation.
