Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interval adjustment mechanism for an elevating type home fence, and in particular, an elevating type home fence in which intervals between protective fences such as a plurality of elevating ropes are changed according to respective moving positions up and down by a simple mechanism. The present invention relates to an interval adjusting mechanism.

  In recent years, in order to prevent users such as passengers from falling from the station platform to tracks (tracks) or coming into contact with trains (trains) that have entered the station platform, Home safety fences are being provided along the edge of the platform on the track side. Conventionally, there are various types and structures of home safety fences. For example, there is a protective wall type with a waist height with a side door platform door installed at a position corresponding to the entrance door of a train stopped at the station platform, or a person along the edge of the station platform on the track side like a subway A protective wall type that forms a wall entirely up to a height exceeding the height of the train, and has a laterally opening and closing door corresponding to the position of the entrance door of the train, or almost the entire area along the edge of the station platform on the track side There is an elevating rope safety fence or the like (Patent Document 1 below) formed by arranging an elevating rope. There are also safety fences that use long bars and rods instead of ropes.

  Moreover, the safety fence which has the gate structure disclosed by the following patent document 2 and patent document 3 is also proposed. Patent Documents 2 and 3 are patent applications by the same applicant, and the basic configuration of the gate device disclosed in Patent Documents 2 and 3 is the same. The gate device of Patent Document 2 has a front shape (changed from closed to open) as shown in FIG. 4, and corresponds to each position of a plurality of entrance doors of a train stopped at the station platform. Installed at home. The gate device has a pair of left and right fixed struts fixed to the floor of the station platform (11: numbers in parentheses are numbers used in the gazette; the same applies hereinafter) and each fixed strut (11). A movable support column (12) that slides up and down, and an upper stop bar (13) and a lower stop bar (14) that moves up and down between the left and right movable columns (12). As shown in FIGS. 2 and 5, the gate device disclosed in Patent Document 3 also slides up and down with respect to a pair of left and right fixed columns (11) fixed to the station platform and each fixed column (11). It consists of a pair of left and right movable struts (12), an upper stop bar (13), and a lower stop bar (14) that moves up and down.

  For example, as shown in FIGS. 4 and 5 of Patent Document 2, when the movable column (12) is in the lowered position and the gate device is closed, the upper stop bar (13) and the lower stop bar (14). When the movable strut (12) is in the raised position and the gate device is open, the lower restraining bar (14) moves upward and approaches the upper restraining bar (13). The distance between the stop bar (13) and the lower stop bar (14) is narrow. This configuration is the same as that of the gate device disclosed in Patent Document 3. As described above, in the gate devices disclosed in Patent Documents 2 and 3, the distance between the upper stop bar (13) and the lower stop bar (14) is variable during ascent and descent. In order to make the distance between the upper stop bar (13) and the lower stop bar (14) variable, a drive mechanism (control unit and drive unit) for moving the lower stop bar (14) up and down is provided on the movable column (12). ing.

Special table 2008-526614 JP 2012-106586 A (FIGS. 4 and 5 etc.) Japanese Patent Laying-Open No. 2011-173854 (FIGS. 2 and 5, etc.)

  The gate devices disclosed in Patent Documents 2 and 3 are arranged corresponding to the positions of the entrance doors of the train, and left and right support posts are installed at a distance corresponding to the door width of the entrance doors of the train. The top and bottom stop bars are arranged on the top. The left and right columns are each composed of a fixed column and a movable column that slides up and down with respect to the fixed column. The upper and lower restraining bars are provided on the movable strut, and in particular, the lower restraining bar is configured to be lifted and lowered by a drive mechanism provided on the movable strut when the movable strut is lifted and lowered. The raising / lowering operation of the lower restraining bar is independent of the raising / lowering operation of the movable column, and the raising / lowering operation of the lower blocking bar is performed after the raising / lowering operation of the movable column is completed. For this reason, the drive mechanism that performs the lifting and lowering operation of the lower restraining bar is provided as a drive element that is separate from the drive mechanism that performs the lifting and lowering operation of the movable column. Therefore, the structure of the drive mechanism for raising / lowering operation is complicated.

  In view of the above-described problems, the object of the present invention is such that each interval of protective fences such as a plurality of ropes that move up and down is configured to change according to each moving position up and down by a simple mechanism, and at low cost. An object of the present invention is to provide an elevating type home fence interval adjusting mechanism capable of realizing the mechanism.

  In order to achieve the above object, the lifting / lowering platform fence interval adjusting mechanism according to the present invention is configured as follows.

The distance adjustment mechanism (corresponding to claim 1) of the first liftable home fence is

In this structure, it is bridged between two pulleys arranged in a vertical relationship. An annular member, and the annular member is coupled to a connecting portion provided on the column portion,
One guard fence is coupled to an annular member, and when the structure is raised and lowered, the guard fence is raised when the structure is raised, and one guard fence is lowered when the structure is lowered. ,
With the vertical movement of the structure itself, characterized in that so as to vary the spacing.

  In the above-described lifting / lowering home fence interval adjusting mechanism, it is possible to change the interval between each of at least two protective fence parts (ropes, etc.) by interlocking with the raising / lowering operation of the raising and lowering structure part itself. In order to change the interval between the protective fences, it is not necessary to provide a separate drive device and drive control device.

In the above configuration, the second elevating-type home fence spacing adjustment mechanism is preferably configured in accordance with the movement of raising or lowering one of the at least two protective fence parts. It is characterized by interlocking the raising and lowering of the protective fence, and narrowing the interval when ascending and closing it with a wider interval when descending.
According to this configuration, when one guard fence is raised and lowered, the remaining guard fences are also raised and lowered, and when they are lifted, all guard fences are in a state where their intervals are narrowed together. It moves to the upper position, and the open state of the home fence is created on the lower side, and when it descends, the distance between the guard fences becomes wider and moves to the lower position, and the home fence is closed to function as a guard fence.

In the above configuration, the third elevating-type home fence interval adjusting mechanism preferably corresponds to the movement of raising / lowering any one of the at least two protective fence parts. It is characterized in that the protection fence part is moved up and down, and is closed with a wide interval when ascending, and is opened with a narrow interval when descending.
According to this configuration, it is configured to be opposite to the second device configuration described above, and at the time of ascent, the intervals between the plurality of protective fences arranged with the intervals narrowed at a predetermined position below are increased and closed. It is made to function as a protective fence, and when descending, the interval between the protective fences is narrowed and moved to a predetermined position below to create an open state of the home fence.

The distance adjustment mechanism (corresponding to claim 4) of the fourth elevating type home fence is preferably characterized in that, in the above configuration, the motor is built in the support column .

  In the above-described configuration, the fifth elevating-type home fence interval adjusting mechanism (corresponding to claim 5) is preferably characterized in that the protective fence portion is a rope spanned in the horizontal direction.

  According to the present invention, the structure part that supports a plurality of ropes and the like that are arranged at intervals has a mechanism that changes the distance in accordance with the raising / lowering operation of the structure part itself, and the structure part itself that is raised and lowered Since the intervals of the plurality of ropes and the like are changed based only on the operation, there is no need to provide a drive device and a drive control device for changing the intervals, and the intervals of the plurality of ropes that are moved up and down can be changed by a simple mechanism. The distance adjustment mechanism can be realized at a low cost because it can be changed according to each moving position.

  DESCRIPTION OF EMBODIMENTS Preferred embodiments (examples) of the present invention will be described below with reference to the accompanying drawings.

  With reference to FIGS. 1-3, 1st Embodiment of the space | interval adjustment mechanism of the raising / lowering platform fence which concerns on this invention is described.

  In FIG. 1, reference numeral 10 denotes a liftable platform fence. In the elevating platform fence 10, reference numeral 11 denotes a support column, and 12 denotes an elevating part. The column 11 is fixed to the home floor 13. The elevating part 12 is supported by a guide mechanism (not shown) in the support column 11 and is moved up and down (ascending (A) or descending (B)) in the height direction of the support column 11 by this guide mechanism. ing. Inside the column 11, a drive unit 14 that raises and lowers the elevating unit 12 is provided. When the drive unit 14 performs the ascending drive 14A via the guide mechanism, the elevating unit 12 is raised (A), and when the descending drive 14B is performed, the elevating unit 12 is lowered (B). As the configuration of the drive unit 14 and the configuration of the guide mechanism, a well-known device configuration that has been well known in the past can be used, and can be arbitrarily designed.

  In the elevating part 12, two pulleys 16 and 17 that freely rotate are provided in an upper and lower positional relationship inside a case 15 that forms an outer appearance part, and an annular shape is provided between the two pulleys 16 and 17. The belt 18 is stretched over. A predetermined portion of the annular belt 18 is joined to a tip portion of a connecting portion 19 fixedly provided at an upper portion of the column 11.

  Further, for example, four rope holders 21A, 21B, 21C, and 21D are sequentially provided from the top inside the elevating unit 12 based on the positional relationship in the vertical direction. In the rope holder 21A, the uppermost rope 22A is coupled, and the rope holder 21A holds the rope 22A horizontally. In the rope holder 21B, the second rope 22B from the top is coupled, and the rope holder 21B holds the rope 22B horizontally. In the rope holder 21C, the third rope 22C from the top is coupled, and the rope holder 21C holds the rope 22C horizontally. The rope holder 21D is coupled to the lowest (fourth from the top) rope 22D, and the rope holder 21D holds the rope 22D horizontally. 2 shown in FIG. 2 has each coupling | bond part between the rope holders 21A-21D and the ropes 22A-22D. The shape of the rope holder 21A is, for example, a trapezoid, and each shape of the rope holders 21B to 21D is, for example, a narrow plate shape. The shape of the rope holders 21A to 21D can be arbitrarily designed according to the purpose and conditions.

  Moreover, in this raising / lowering type home fence 10, it is set as the structure which uses four ropes 22A-22D laid in the horizontal direction at intervals as a protection fence part to raise / lower. The distance between each of the four ropes 22A to 22D is variable according to the height position. In addition, as a guard fence part, arbitrary members, such as a bar, which have a similar shape and structure can be used.

  Bar-shaped members 21A-1, 21B-1, and 21C-1 that are directed downward are provided at arbitrary predetermined positions on the lower surfaces of the rope holders 21A to 21C. Each lower end part of rod-shaped member 21A-1 to 21C-1 is formed as an enlarged diameter part. As shown in FIG. 2 in which the main part of FIG. 1 is enlarged, the rod-shaped member 21A-1 is inserted into a hole 21B-2 formed in the rope holder 21B on the lower side of the rope holder 21A. Yes. The rod-shaped member 21B-1 is inserted into a hole 21C-2 formed in the rope holder 21C arranged on the lower side of the rope holder 21B. The rod-shaped member 21C-1 is inserted into a hole 21D-2 formed in the rope holder 21D arranged on the lower side of the rope holder 21C.

  With respect to the attachment positions of the rope holders 21 </ b> A to 21 </ b> D, the rope holder 21 </ b> A located at the top is fixed to the upper part of the case 15 of the elevating unit 12. Therefore, the rope holder 21A is fixed at a fixed position in the case 15 of the elevating unit 12, and is always stationary. The rope holder 21D located at the lowest position is coupled to the predetermined position of the belt 18 described above. Accordingly, the rope holder 21 </ b> D moves with the movement of the belt 18. The two rope holders 21B and 21C located in the middle are related to the rope holders 21A and 21D in a link mechanism by the rod-like members 21A-1, 21B-1, and 21C-1. The movement is restricted. That is, when the lowermost rope holder 21D rises in response to the movement of the belt 18, the rope holder 21D is pushed upward in conjunction with this, and the rope holders 21B and 21C are also rod-like members 21A-1 to 21C. Ascends so as to approach the rope holder 21A while the lateral movement is restricted by -1. On the other hand, when the rope holder 21D descends in response to the movement of the belt 18, the rope holders 21B and 21C move downward by their own weight while their lateral movement is restricted by the rod-like members 21A-1 to 21C-1.

  The state shown in FIG. 1A shows a state in which the elevating unit 12 is raised (A) to the highest position based on the ascending drive 14A by the drive unit 14. At this time, since the belt 18 is coupled to the connecting portion 19, the belt 18 rotates counterclockwise, and as a result, the rope holder 21D coupled to the belt 18 moves upward and downward. In conjunction with this, it rises in the case 15 of the elevating unit 12. When the rope holder 21D rises, it is pushed up by the rope holder 21D and the rope holders 21B and 21C also rise. Finally, the rope holder 21D is pressed against the rope holder 21A, and the four rope holders 21A, 21B, 21C, and 21D come to rest in a state where they are substantially in contact with each other. As a result, when the elevating unit 12 is raised, the intervals between the four ropes 22A, 22B, 22C, and 22D are reduced. Thereby, when the raising / lowering part 12 raises, the lower space of rope 22A-22D is open | released, and the raising / lowering type home fence 10 will be in the open state.

  The state shown in FIG. 1B shows a state in which the elevating unit 12 is lowered (B) to the lowest position based on the descent drive 14B by the drive unit 14. At this time, since the belt 18 is coupled to the connecting portion 19, the belt 18 rotates in the clockwise direction. As a result, the rope holder 21 </ b> D coupled to the belt 18 is interlocked with the movement of the elevating unit 12 descending. Then, it descends in the case 15 of the elevating part 12. When the rope holder 21D is lowered, the rope holders 21B and 21C are also lowered by its own weight. Finally, when the rope holder 21D comes to the lowest position, the intermediate rope holders 21B and 21C are respectively regulated by the rod-like members 21A-1 and 21B-1 that are in an engaging relationship, and the rod-like member It is stopped at a lower position determined by the length of. The position of the lowest rope holder 21D is also determined by the length of the rod-shaped member 21C-1. As a result, when the elevating unit 12 is lowered, the intervals between the four ropes 22A, 22B, 22C, and 22D are expanded in the vertical direction, and are separated at a desired interval. Thereby, when the raising / lowering part 12 descend | falls, the four ropes 22A-22D are arrange | positioned at a suitable space | interval, and the raising / lowering type home fence 10 will be in the closed state.

  The ascending state (A) and the descending state (B) shown in FIG. 1 are repeated alternately at an appropriate timing required. That is, when the elevating unit 12 is driven up, it changes from (B) in FIG. 1 to (A), and when the elevating unit 12 is driven down, it changes from (A) to (B) in FIG. When the raising / lowering part 12 raises / lowers, it is comprised so that the space | interval of the four ropes 22A-22D may change. That is, the distance between the ropes 22A to 22D is wide when in the lowered state, and the distance between the ropes 22A to 22D is narrowed when the raised state. As a result, the elevating platform fence 10 is opened and closed.

  As described above, the entire height of the casing portion of the liftable home fence 10 composed of the support column 11 and the lifting part 12 is configured by narrowing the interval between the plurality of ropes 22A to 22D as the protective fence part when rising. There is an advantage that it can be kept low.

  Next, with reference to FIG. 3, the spacing adjusting mechanism for the ropes 22A to 22D of the elevating platform fence 10 will be conceptually described. That is, when the lifting / lowering operation 32 is performed on the structural unit 31 (corresponding to the lifting / lowering unit 12) based on a driving device (not shown), the relationship 33 (the belt 18, the connecting unit 19, A mechanism 34 (corresponding to the rope holders 21A to 21D, the rod-like members 21A-1 to 21C-1 and the like) that changes the interval based on the rope holder 21D or the like) is provided. , 36 (corresponding to the ropes 22A to 22D). In other words, the distance adjusting mechanism of the liftable platform fence 10 has a feature in that the distance 37 between the protection fence portions 35 and 36 is changed based on the lifting operation of the structure portion 31, and the distance 37 is changed. Therefore, there is an advantage that a dedicated drive mechanism and a control unit are not required.

  As shown in FIG. 1, a plurality of necessary units are installed along the track-side edge of the station platform in the casing portion including the column 11 and the lifting unit 12 of the lifting platform fence 10. The ropes 22 </ b> A to 22 </ b> D are held to form a rope erection state. FIG. 4 is a diagram illustrating an arrangement state of the two liftable platform fences 10. The four ropes 22A to 22D are held via the lifting parts 12 of the two lifting platform fences 10, each lifting part 12 is in a lowered state, and the lifting platform fence 10 is in a closed state. .

  Next, with reference to FIG. 5, 2nd Embodiment of the space | interval adjustment mechanism of the raising / lowering platform fence which concerns on this invention is described. 5A corresponds to FIG. 1A, and FIG. 5B corresponds to FIG. 1B. In FIG. 5, elements that are substantially the same as those described in FIG. 1 are given the same reference numerals, and redundant descriptions are omitted. In FIG. 5, the illustration of the lower part of the column 11 is omitted.

  In FIG. 5, the shape and internal structure of the support 11, the attachment position of the connecting portion 19, the case 15 of the elevating / lowering portion 12, the pulleys 16 and 17 in the case 15, and the belt 18 laid between the two pulleys 16 and 17. The configuration of is the same as that of the first embodiment described in FIG. Therefore, the raising / lowering operation of the raising / lowering part 12 and the rotation operation of the belt 18 accompanying the said raising / lowering operation are as having demonstrated in 1st Embodiment.

  A mounting base 40 is provided in the upper part of the elevating part 12 in the case 15. On the lower side of the mounting base 40, for example, four rope holders 41A, 41B, 41C, 41D are sequentially arranged from the top based on the positional relationship in the vertical direction. Rope 22A-22D is couple | bonded with each of rope holder 41A-41D, and each rope holder 41A-41D hold | maintains each corresponding rope 22A-22D horizontally. The uppermost rope holder 41A is fixed to the mount 40, and one end of the lowermost rope holder 41D is coupled to the belt 18. The rope holders 41A to 41D have, for example, a narrow plate shape. The four rope holders 41 </ b> A to 41 </ b> D each include a link mechanism 42 that makes a so-called magic hand structure by using one side surface thereof, and are connected by these three link mechanisms 42. In each of the three link mechanisms 42, the coupling portions with the rope holders 41 </ b> A to 41 </ b> D are provided so as to slide in the lateral direction (horizontal direction) in FIG. 5.

  As shown in FIG. 5A, the rope holders 41 </ b> A to 41 </ b> D connected by the link mechanism 42 move the rope holder 41 </ b> D coupled to the belt 18 to the belt 18. Ascending with the counterclockwise rotational movement, each link mechanism 42 is closed, and the rope holders 41A to 41D are substantially in contact with each other. As a result, the four ropes 22 </ b> A to 22 </ b> D are raised and the interval between them is narrowed. Further, as shown in FIG. 5B, when the elevating part 12 is lowered, the rope holder 41D coupled to the belt 18 is lowered along with the clockwise rotation of the belt 18, and each link mechanism 42 is moved. The rope holders 41 </ b> A to 41 </ b> D are widened so as to be a desired distance by opening in the vertical direction. As a result, the four ropes 22 </ b> A to 22 </ b> D are lowered and the distance between them is widened.

  As described above, even in the configuration based on the link mechanism 42 according to the second embodiment, the intervals between the plurality of ropes 22A to 22D, which are protective fences, can be narrowed when ascending. There is an advantage that the overall height of the casing portion of the liftable platform fence 10 composed of the lifter 12 can be kept low.

  The interval adjusting mechanism for the liftable platform fence according to the present invention can also be configured as follows. According to each of the above embodiments, when the rope is raised, the distance between the ropes is narrowed to create an open state of the home fence on the lower side of the rope, and when the rope is lowered, the distance between the ropes is widened to keep the closed state of the home fence. It was configured to make. On the other hand, it can be configured such that when the rope is raised, the distance between the ropes is widened to create a closed state of the home fence, and when the rope is lowered, the distance between the ropes is narrowed to create an open state of the home fence. In this case, the plurality of ropes are configured to be raised from a predetermined lower position during the closing operation and to be lowered to a predetermined lower position during the opening operation.

  The configurations, shapes, sizes, and arrangement relationships described in the above embodiments are merely schematically shown to the extent that the present invention can be understood and implemented, and the numerical values and the compositions (materials) of the respective components Is just an example. Therefore, the present invention is not limited to the described embodiments, and can be variously modified without departing from the scope of the technical idea shown in the claims.
