Description

  The present invention relates to a movable platform fence door installed on a railway vehicle platform, and more particularly to a door front end locking mechanism.

  FIG. 34 is a configuration diagram showing one side of a general home fence door (hereinafter simply referred to as a door). The door pocket 50 includes two pillars 51 and a cross beam 52 on the door bottom side and the door tip side. The door 1 is fixed to a bearing bracket 53, and two linear guide bearings 54 are fixed to the bearing bracket 53. The linear guide bearing 54 is configured to be able to move on a linear guide 55 fixed to the door pocket 50. The door 1 is opened and closed by a timing belt 57 driven by a motor 56. In FIG. 34, the exterior panel of the door pocket is omitted.

  The door 1 is supported by the linear guide bearing 54 and moves on the linear guide 55 in the direction of the arrow, and enters and exits the door pocket 50 to open and close the door 1.

  When the door is bent in the platform fence placed on the platform, when the door is bent against 100 kg of pressure per 1 m length by passengers coming from the platform side, a certain distance from the train (safety limit) There is a safety regulation that must not bend more. Therefore, the door has to be rigid so as not to bend with respect to the load, and the structure in the door pocket, such as a pillar and a horizontal beam supporting the door, has to have strength to withstand it. For this reason, as a structure to increase the rigidity of the door, it was necessary to arrange a strong material such as an iron pipe inside the door, and also to give the pillar enough rigidity to withstand the rotational force (moment) received from the door. .

  FIG. 35 is a view of the home fence door 1 as viewed from above. Here, when the door 1 is pressed, for example, from the home side, the door 1 bends with the door-side column 51 as a fixed end as shown in FIG. At this time, since the door 1 is in a cantilever state, the door 1 can withstand the pressure only by the rigidity of the door 1. In addition, when a pressure F is applied to the door 1, a rotation moment of a pressure F * door length L (= L * F) is applied to the door-side column 51 in addition to a pressure (= F) applied to the door 1. It will be.

Here, when the column 51 is twisted by this rotational moment, the door 1 is rotated from the base, and the position of the front end of the door is rotated from the column 51 that fixes the door in addition to the fall of the door 1 against the pressing. Since the minutes are added, the door front end portion is further displaced toward the track side. For this reason, the column 51 is required to have higher strength. That is, when the door 1 is pressed horizontally by passengers, as shown in FIG.
Displacement a due to deflection of door 1
Displacement b due to the collapse of the column 51 due to pressing,
The displacement c due to the rotation of the door 1 by the rotation of the column 51 by the rotation moment,
These three types of displacement occur.

This will be explained with reference to FIG. 37. In general, in the case of the door 1 having a length of about 1.5 m, when the pillar 51 is a 50 mm square iron rod, when a predetermined 75 kg of pressure is applied to the door tip,
Displacement a due to deflection of door 1: 16 mm
Displacement b of column 51 due to pressing b: 4.1 mm
The column 51 is twisted by the rotational moment, and the displacement c due to the rotation of the door 1 is 19 mm.
Therefore, the influence of the bending of the door 1 and the rotation of the column 51 is large, and it is necessary to increase the rigidity of the door 1 and the column 51.

  In order to increase the rigidity of the door 1 against bending, a structure in which an iron pipe is disposed inside the door 1 and the outside is covered with an iron plate is generally required, and it is necessary to increase the rigidity by increasing the thickness. In particular, when glass is attached to the door 1, the portion requiring rigidity against bending is the central portion 1a of the door 1 in FIG. 34, but since this portion is attached with glass, a strength material can be disposed. In addition, a structure that can withstand pressing only at the upper and lower portions of the door 1 is required. Therefore, it is necessary to configure the upper and lower portions of the door 1 with more strength materials such as pipes, and the weight of the door 1 becomes heavier. In addition, the increase in the weight of the door 1 causes an increase in the size of the motor 56 that drives the door, an increase in the size of the linear guide 55 for moving the door left and right, and an increase in the size of the rail that supports the linear guide 55.

  As a conventional technique for avoiding such a heavy door from tilting the front end of the door toward the track side or in the opposite direction at the position where the door is closed, Prior Art Document 1 (Japanese Patent Application Laid-Open No. 2002-2000). As shown in FIG. 1 of Japanese Patent No. 220047), there is a door in which a key that can move horizontally with respect to the door is attached.

  In prior art document 1, it is necessary to incorporate a part including a drive unit such as an electromagnetic solenoid in the movable door, and the structure is complicated, and a cable for sending a drive signal and power to the movable door. The structure of the fixed part of the door pocket and the movable door was complicated. Also, for example, if the length of one door is 1 m, a load of 50 kg is applied to the tip, but the key is parallel to the door, and if the door rigidity is weak, the key will slip and escape from the guide. Could not be prevented from opening in the direction of the track or in the opposite direction.

Japanese Patent Laid-Open No. 2002-220047

  The present invention has been made to solve the above problems, and when the door is closed, the door does not open even when a pressure in a direction perpendicular to the door is applied, and the door is normally opened and closed. It is intended to obtain a movable platform fence door with a simple structure that does not require much effort.

  Embodiments of the present invention will be described below, but the structure of the movable home fence door is a general structure shown in FIG. 34 except for the structure of the front end portion of the door, and is therefore omitted in the description of each embodiment. . Moreover, the same code | symbol shall show the same or equivalent element in a figure, and description may be abbreviate | omitted.

Embodiment 1 FIG.
The structure of the front-end | tip part of the door which concerns on Embodiment 1 is shown in FIG. The figure is a plan view of a front end portion of the left and right doors 1 as viewed from above. The front end of the door 1 has an uneven shape that fits together. For example, the tip of the right door 1 has a convex cross section, and the convex tip has an arrowhead shape, and hooks 2 are provided at the D portion surrounded by a dotted line, that is, both hems of the arrowhead shape. The tip of the left door 1 facing the right door 1 has a concave cross section, and the hook 3 is engaged with the convex hook 2 on the E portion surrounded by a dotted line, that is, both inner edges of the concave portion. Is provided. A buffer member 4 is provided at the convex tip of the right door 1 and a buffer member 5 is provided at the concave periphery of the left door 1 to alleviate the impact when the left and right doors 1 are closed. It is made like that.

  As shown in FIGS. 1 and 2, the door 1 that normally slides with a linear guide advances and retreats straight from the door pocket at the time of normal opening and closing. The doors 1 are opened and closed smoothly without being engaged.

  When the door 1 is closed, as shown in FIG. 3, for example, when the right door 1 is pressed in the direction of arrow G, as shown in FIG. The hook 3 on the track side (upper side in the drawing) of the door 1 and the hook 2 of the right door 1 are engaged with each other, and the door 1 is locked so as not to open. Similarly, when H is applied to the left door 1, the opposite is true, and the hook 3 on the home side (lower side in the figure) of the left door 1 and the hook 2 of the right door 1 are engaged with each other. Is locked from opening.

  As shown in FIG. 4, the fitting portion due to the unevenness of the door tip can be provided at any position from the upper part to the lower part of the door 1. For example, the stress applied to the pressure G of FIG. 3 on the entire door of FIG. 3 is about 3 mm when a prescribed pressure of 75 kg of the door 1 having a length of 1.5 m is applied assuming that a hook is provided from the top to the bottom of the door 1. Even if aluminum is used, it is distorted only by about 0.1 mm. The same effect can be obtained even if the other side is not a door but a fixed end such as a pillar.

Here, an effect when the door tip is locked when the door is pressed vertically in the closed state of the door will be described. FIG. 5 shows a force propagation path by an arrow when a pressure applied by a passenger or the like is applied to the door by a double arrow F force when the door 1 is closed. FIG. 6 shows a force propagation path in which the angle is emphasized so that the component force can be easily understood.
Receives pressing F from passengers.
The force F is divided into the left and right doors 1 and separated into F11 and F12. This force works substantially parallel to the door 1.
The force of F11 is divided by the pillar 51 in the door pocket 50 in the transverse beam direction F111 and the home side direction F112.
Finally, F111 is received by the two pillars 51 as a force parallel to the home. The rigidity in this direction is generally high, and the bending is only negligible. If necessary, it can be dealt with by providing a streak between the column 51 and the cross beam 52 in the door pocket 50. F112 is supported by the rigidity of the pillar 51 on the door-end side. That is, the column 51 is inclined toward the track side.

Here, when the propagation path of the force with the conventional home fence door described above is arranged, in general, in the case of the door 1 having a length of about 1.5 m, when the pillar 51 is a 50 mm square iron bar, the door When a predetermined 75 kg of pressure is applied to the tip,
The displacement due to the deflection of the door 1 is
(Conventional displacement): 16 mm
(Displacement amount of the present embodiment): 0 mm
Only the pulling force is applied to the door 1, and generally metal is strong against pulling, so even a single iron plate has a negligible elongation.
The displacement due to the fall of the column 51 due to the press is as follows:
(Conventional displacement): 4.1 mm
(Displacement amount of the present embodiment): 4.1 mm
The present embodiment is the same as the conventional example for the pressure in this direction.
The column 51 is twisted by the rotation moment, and the displacement caused by the rotation of the door 1 is
(Conventional displacement): 19 mm
(Displacement amount of the present embodiment): 0 mm
Although F12 and F11 are transmitted to the column 51, the column 51 receives only a pulling force parallel to the door 1, not a rotational moment. That is, the column 51 is not twisted, and the front end of the door is not displaced by the twist of the column 51.

  Thereby, the door does not need to be rigid with respect to deflection, and a lightweight, thin and cheap door can be configured. As a result, it is possible to reduce the size of the motor for driving the door and the size of the drive rail, and to make the door pocket structure light and inexpensive. In addition, since the door is light, the power required for opening and closing the door can be reduced, so that an energy-saving home fence can be obtained. In addition, it is only necessary to consider only the collapse of the column to the track side, and it is possible to reduce the weight and the cost.

  In the closed state of the door described above, when the door is pressed vertically, the effect of locking the door tip so that it does not open is the same for all of the following embodiments.

Embodiment 2. FIG.
Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, a hook structure is provided at the front end of the door, and the hook is engaged by a vertical press applied to the door to lock the door. Each of the drawings is a plan view of the front end portion of the door as viewed from above.

  The difference between the second embodiment and the first embodiment is that the first embodiment has a structure in which a concave shape and a convex shape are provided at the front end of the door. It is a point that a hook is provided on a part of the slope. This will be described in detail below.

  FIG. 7 shows a normally open state where the door 1 is not subjected to vertical pressure. As for the front-end | tip of the doors 1 on either side, the opposing part of both the doors 1 has the slope 6 so that one board may be cut | disconnected diagonally in the thickness direction, for example. On the slope 6, hooks 7 that engage with each other are formed. A buffer member 8 is attached to the tip of each door 1. FIG. 8 shows a normal closed state where the door 1 is not subjected to vertical pressure. As shown in FIGS. 7 and 8, when no vertical force is applied to the door 1, the door 1 freely opens and closes.

  FIG. 9 shows a case where a vertical pressure is received in a state where the door 1 is closed. When the left door 1 receives the pressure J, the left door 1 is pressed, the hooks 7 of the left and right doors 1 are engaged with each other, and both the doors 1 are locked so as not to open. This is the same when the right door 1 is pulled in the direction opposite to J. However, in the structure of FIGS. 7 to 9, when the right door 1 is pushed in the same direction as J, or when the left door 1 is pulled in the direction opposite to J, the hook is not hooked. Unable to lock 1 open.

Therefore, as shown in FIG. 10, a structure is prepared in which the front end of the door has an inclined surface in which the hook direction is opposite to that of FIGS. The structure shown in FIGS. 7 to 9 is called an A pattern, and the structure shown in FIG. 10 is called a B pattern. And the structure of A pattern and B pattern is divided | segmented and arrange | positioned in the up-down direction of the door 1. FIG. FIG. 11 is a perspective view showing this configuration, and shows an example in which the A pattern portion is arranged at the upper portion of the front end of the door 1 and the B pattern portion is arranged at the lower portion. If one door on the right side is pulled in the M direction or the left door 1 is pulled in the N direction, the hooks on the pattern A will engage, and the right door 1 will be in the N direction and the left door 1 in the M direction. When pulled, the hooks of the B pattern portion engage with each other. As a result, the hook locks the opening of the door 1 regardless of which door is pushed or pulled in any direction. A plurality of these A and B pattern portions may be alternately arranged. The same effect can be obtained even if the other side is not a door but a fixed end such as a pillar. Of course, in a normal state where no pressure is applied, the door is freely opened and closed.
The above describes an example in which both the A pattern and B pattern hooks are provided on one door or fixed end when the door is closed and the door and fixed end are closed, but the door and fixed end are closed. Assuming that the door is pressed vertically from the home side and only trying to prevent the door from flexing to the track side, the A pattern or B pattern hook is attached to the door and the fixed end is It is also possible to provide only a B pattern or A pattern hook that hooks onto the hook.

  According to the second embodiment, the hook portion can be deeper than the same thickness door. In addition, the thickness of the hook portion can be increased when the prescribed pressure is large with a very long door or the like.

Embodiment 3 FIG.
12-20 is a figure explaining the structure and operating principle of the movable platform fence door which concern on Embodiment 3 of this invention. The third embodiment is different from the second embodiment in that the second embodiment performs locking using a hook, whereas the third embodiment performs locking without using a hook.

  FIG. 12 is a plan view showing the front end portion of the door according to the third embodiment, and the front end of the door 1 has a portion where both doors 1 face each other as if a single plate is cut obliquely in the thickness direction. It has a slope 6. On the other hand, FIG. 13 shows a structure in which the direction of the slope 6 is opposite to that in FIG. Here, the structure of FIG. 12 is temporarily called a C pattern, and the structure of FIG. 13 is temporarily called a D pattern. In the third embodiment, the configurations of the C pattern and the D pattern are arranged separately in the vertical direction of the door 1. FIG. 16 is a perspective view showing this configuration, and shows an example in which a C pattern portion is arranged at the top of the front end of the door 1 and a D pattern portion is arranged at the bottom. In this way, even when the door 1 is subjected to a vertical pressure, the door 1 is locked closed and can be normally opened and closed without any trouble.

  FIGS. 17 and 18 are operation explanatory views when the right door 1 is pressed in the arrow S direction. When the pressing of S is applied to the right door 1, the K portion contacts the slope 6 of the C pattern door 1 shown in FIG. 17. At this time, the portion L of the slope 6 of the door 1 of the D pattern shown in FIG. As described above, since the C pattern and the D pattern are provided above and below the end face of one door 1, the right door and the left door are in a state of being bitten at the positions of K and L, as in the second embodiment. Will be locked. In particular, it is possible to lock more effectively by adopting a concave / convex shape that does not easily cause a slip at a contact site, or a material or shape that increases friction.

  12 and 13, the inclined surface 6 is provided at the front end of the door 1, but instead of the inclined surface, a protruding portion 60 having a rectangular planar cross section that overlaps the side surface may be formed at the front end of the door 1. . 14 and 15 are plan views thereof, and are referred to as a C pattern and a D pattern, respectively, similarly to FIGS. 12 and 13. Although not shown in the drawings, the structure of the C pattern and the D pattern of FIGS. 14 and 15 is arranged on each door 1 in the same manner as in FIG. Is closed and locked, yet it can be opened and closed normally.

  FIG. 19 and FIG. 20 show the operation, and when the right door 1 is pressed with T, the protruding portion 60 of the C pattern door 1 shown in FIG. At this time, the projecting portion 60 of the D pattern door 1 shown in FIG. As described above, since the C pattern and the D pattern are provided above and below the end face of one door 1, the right door and the left door are in a state of being bitten at the positions of R and U, as in the second embodiment. Will be locked. In particular, it is possible to lock more effectively by adopting a concave / convex shape that does not easily cause a slip at a contact site, or a material or shape that increases friction.

Embodiment 4 FIG.
Next, a fourth embodiment of the present invention will be described with reference to FIGS. The structure of the home fence door is the same as that of FIG. 1 except for the front end of the door. FIG. 21 is a plan view of the door 1 opened and FIG. 22 is a plan view of the door 1 as viewed from above. In the fourth embodiment, the front end cross section of the right door 1 is a convex portion 9 smaller than the door thickness, while the front end cross section of the left door 1 is a concave portion 10 and the convex portion 9 is fitted into the concave portion 10. Nested structure. Of course, the uneven structure of the left and right door tips may be reversed from the figure. A chamfer 11 is applied to the tip of the convex portion 9, and a chamfer 12 is also applied to the inner edge of the opening of the concave portion 10.

  In this structure, in a normal state where no vertical pressure is applied to the door 1, as shown in FIG. 22, since the convex portion 9 is inserted and removed straight into the concave portion 10, there is no problem in opening and closing the door 1. FIG. 23 shows a case where the door 1 receives vertical pressure. When the door 1 is closed and the pressure of the arrow P is vertically applied, as shown in FIG. 23, the convex portion 9 and the concave portion 10 come in contact with the circled portions K and L, and the friction force The door 1 can be prevented from opening. Even when a pressure in the direction opposite to the arrow P is received, the closing of the door 1 is locked according to the same principle. The same effect can be obtained even if the other side is not a door but a fixed end such as a pillar.

  The fourth embodiment has a feature that the structure is simple. In addition, no electrical equipment is required as compared with the conventional example.

Embodiment 5. FIG.
24 to 27 show a fourth embodiment of the present invention. As shown in FIG. 24, the lock mechanism according to the fifth embodiment is provided with a handle 13 having a bar-like body formed at the tip of the right door 1 and fitted with the handle 13 at the tip of the left door 1. A grip 14 is provided. Conventionally, such a lock mechanism is locked when the handle is gripped by the gripping portion at the time of locking, and in order to release the lock, an operation of pulling a separate unlocking lever is performed. Therefore, a special release operation is required and the structure is complicated.

  25 to 27 show only the handle 13 and the gripping part 14 taken out. The gripping part 14 includes a base material 15 having a recess for receiving the handle 13, a bifurcated member 16 pivotally attached to the base material 15, and a connecting rod that is pressed and moved by the pivoting of the bifurcated member 16. 17 and a release lever 18 whose one end is kicked by the connecting rod 17 to release the lock.

  FIG. 25 shows the handle 13 and the grip 14 when the door 1 is open. At this time, the bifurcated member 16 is inclined to the handle 13 side. In the closed state of the door 1 shown in FIG. 26, the handle 13 is engaged with the fork portion of the bifurcated member 16, and at the same time, the bifurcated member 16 is rotated to an upright position, whereby the bifurcated member 16 causes the handle 13 to move. Lock it. At this time, there is still a slight play between the doors 1 in the forward / backward direction. In this locked state, the door 1 does not open, so even if a vertical pressure is applied to the door 1, it is difficult for the door to bend or moment to the pillar. In order to release the lock, as shown in FIG. 27, the right door 1 is slightly advanced and pushed into the grip 14 side. As a result, the bifurcated member 16 rotates counterclockwise in the figure, and one end of the bifurcated member 16 pushes the connecting rod 17, and the connecting rod 17 kicks the release lever 18, whereby the lock is released. Return to the state and the door 1 opens. Since the door 1 is generally controlled by a motor with a position control mechanism such as a resolver, the movement of the door 1 can be controlled with an accuracy of about 0.1 mm, and the door 1 is slightly moved forward when unlocked. Control is easily realizable. The lock release mechanism generally exists under a name such as a push catch, and a detailed description thereof will be omitted.

  According to the fifth embodiment, the unlocking of the door can be performed with only a slight forward movement of the door, so there is no need to manually operate the release lever. The same effect can be obtained even if the other side is not a door but a fixed end such as a pillar.

Embodiment 6 FIG.
The sixth embodiment relates to a door locking mechanism provided with a U-shaped handle 13 provided at the tip of one door 1 and a lock 19 having a lock release mechanism provided at the tip of the other door 1. Is. In this embodiment, as the unlocking mechanism, when the door 1 is large and requires a large locking force, or the door 1 needs to be provided with a special lock, the grip as shown in the fifth embodiment is used. Applicable when the part cannot be used or when it is not possible to avoid opening the door by passengers.

  FIG. 28 does not include a drive unit for unlocking the door, and the wire 20 connected to the unlocking mechanism of the lock 19 can be operated by a control circuit in the door pocket 50. In FIG. 28, a wire 20 is stretched from a lock release lever 22 of the lock lock 19 to a pulley 23, a pulley 24, a solenoid pulley 25, and a wire fixing end 26. The solenoid pulley 25 is connected to the solenoid 21, and the solenoid 21 is driven by the control circuit 27. The solenoid 21, the solenoid pulley 25, and the control circuit 27 are built in and fixed to the door pocket 50.

  FIG. 29 is a view when the door 1 is opened. Even when the door 1 is opened and closed, the wire 20 passes through the solenoid pulley 25, and the solenoid pulley 25 is connected to the wire 20 regardless of whether the door 1 is opened or closed. It has a structure that can be pulled. FIG. 30 shows a state in which the handle 1 of the right door 1 is locked by the lock lock 19 with the door 1 closed, and the door 1 is not opened even if the door 1 is pressed in the vertical direction in this state. It has become. FIG. 31 is a diagram showing an operation when the locked state is released. The solenoid 21 is energized by the control circuit 27 and the solenoid pulley 25 is pulled down. As a result, the wire 20 is pulled, and the wire 20 pulls the lock release lever 22 through the pulley 24 and the pulley 23 to release the lock of the lock lock 19. FIG. 32 is a view when the door 1 is opened. The unlocked lock 19 and the handle 13 of the right door 1 are opened and the door 1 is opened.

  By disposing the wire in this way, the lock can be unlocked from the outside, and the internal structure of the door to be opened and closed can be simplified. The same effect can be obtained even if the other side is not a door but a fixed end such as a pillar.

Embodiment 7 FIG.
FIG. 33 shows a seventh embodiment of the present invention, and the handle 13 and the lock lock 19 provided on the door are the same as those in the sixth embodiment. A difference from the sixth embodiment is that a solenoid 21 for unlocking is provided in the door 1 or the lock 19, a control circuit 27 for controlling the solenoid 21 is provided in the door pocket 50, and the solenoid 21 and the control circuit 27 are provided.
