Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an empty can removal weir that excludes an obstacle such as an empty can that has entered a door opening and closing operation range from the opening and closing operation range.
[0002]
[Prior art and problems to be solved by the invention]
As shown in FIG. 18, the empty can 17 or the like left on the floor surface of the passenger compartment of the railway vehicle moves on the floor surface due to vibration or the like during traveling, so that the vehicle stops at the station and the door 1 is opened. During this time, there is a case of entering the position as shown in the figure.
[0003]
Then, when the door 1 is closed in a state as shown in FIG. 18, the empty can 17 and the like move along the lower rail 5. Then, as shown in FIG. 19, the empty can 17 and the like are sandwiched between the door tip portion 3 of the door 1 and the door stop portion 7 of the door frame 11.
If the empty can 17 or the like is interposed at such a position, the door tip portion 3 of the door 1 cannot contact the door stop portion 7 of the door frame 11. That is, the closing operation of the door 1 cannot be completed.
[0004]
Therefore, there is a possibility that the departure time of the railway vehicle will be delayed and the diagram will be disturbed.
Similarly, in a door mechanism applied other than the entrance / exit of the railway vehicle, for example, an elevator door mechanism, the closing operation of the door 1 may be prevented by the empty can 17 or the like.
[0005]
As a preventive measure of such a situation, it may be possible to install a sensor at each door or arrange a person for monitoring, but with such a method, production costs and labor costs increase, It's not a good idea.
Then, this invention aims at providing the empty can exclusion dam for preventing obstructions, such as an empty can, from being pinched | interposed between the door stop part of a door frame, and the door tip part of a door. .
[0006]
[Means for Solving the Problems and Effects of the Invention]
In order to achieve such an object, according to the first aspect of the present invention, when the door is closed, there is an obstacle such as an empty can between the door tip portion of the door and the door stop portion of the door frame. An empty can evacuation weir to prevent pinching, provided on a floor surface in the vicinity of the door stop portion, provided at a position that does not violate the opening and closing operation range in which the door reciprocates. It is characterized by comprising a ridge line that inclines in the closing direction.
[0007]
According to this empty can exclusion weir, empty cans and the like that have entered the position shown in FIG. 18 are eliminated as follows. Although only an empty can is described here, the same effect can be obtained with an empty bottle or the like as long as the rotating body has a cylindrical shape or the like. In addition, there are some shapes other than the above that can achieve the same effect.
[0008]
First, the empty can is pushed and moved toward the door stop portion of the door frame as the door is closed. Then, the empty can comes into contact with a ridge line that is inclined upward in the direction in which the door is closed from the floor surface. And when it is pushed further toward the door stop, the empty can tries to ride on the ridgeline. However, since the empty can has a cylindrical shape, it cannot stably ride on the ridgeline. For this reason, an empty can falls from the ridgeline to the axial line side (center of gravity side) of the empty can. That is, the empty can is excluded at a position where it is not sandwiched between the door stop portion of the door frame and the door tip portion of the door.
[0009]
In this way, this empty can evacuation weir should not be sandwiched between the door stop portion and the door end portion even if an obstacle such as an empty can enters the position as shown in FIG. Therefore, the door closing operation is not hindered by an empty can or the like.
Moreover, the invention according to claim 2 is the empty can evacuation weir according to claim 1, wherein a surface having the ridgeline is provided, and the surface is directed in a direction away from the opening / closing operation range of the door. And tilted downward.
The invention described in claim 3 is the empty can evacuation weir described in claim 1 or 2 , wherein the ridge line is projected onto the floor surface from above and a boundary that defines the opening / closing operation range. It is provided at a position where the line substantially coincides with the line.
[0010]
The ridge line of the empty can exclusion weir is a position that does not hinder the opening and closing operation of the door, and is further provided at a position near the door. There are various sizes of empty cans, but since the ridgeline is provided at such a position, the empty can can reliably fall in a direction away from the door opening / closing operation range after riding on the ridgeline.
[0011]
Thus, since this empty can evacuation weir improves the certainty of empty can removal, the effect of the present invention, that is, the effect that the closing operation of the door is not hindered by the empty can or the like becomes remarkable. Furthermore, the invention according to claim 4 is an application of the empty can evacuation weir according to any one of claims 1 to 3 to a door of an entrance / exit of a railway vehicle, and is provided inside the opening / closing operation range. It is characterized by being.
[0012]
This empty can evacuation weir is applied to a doorway of a railway vehicle. Since empty cans and the like are often left on the passenger compartment floor of a railway vehicle, the effect of the present invention, i.e., the closing of the door, can be achieved by applying the empty can eliminating weir of the present invention to the door of the railway vehicle. The effect that the operation is not hindered by an empty can or the like appears more remarkably.
[0013]
Moreover, since this empty can exclusion dam is provided inside the opening / closing operation range, the empty can is excluded from the ridgeline to the inside of the vehicle.
In this way, when this empty can exclusion weir is applied, the empty can is excluded inside the vehicle, so that a useful effect of not polluting the outside of the vehicle, that is, the track is also exhibited.
[0014]
Furthermore, the invention described in claim 5 is the empty can eliminating weir described in claim 4 , characterized in that it is provided at a position hidden behind the door frame when viewed from the outside of the vehicle. Thus, since it is provided at a position where it cannot be seen from the outside of the vehicle, it has a more useful effect that it is not obstructive and does not impair the orderly appearance inside the vehicle.
[0015]
Some door mechanisms are provided with drainage grooves on the floor surface directly below the open / close operation range in which the door reciprocates. If a drainage groove is provided at such a position, an empty can or the like may fall into the drainage groove while the door is open. It may be difficult to eliminate empty cans or the like existing at such a position by an empty can eliminating weir provided at a position that does not violate the open / close operation range.
[0016]
Therefore, the invention according to claim 6 is to prevent an obstacle such as an empty can from being caught between the door tip portion of the door and the door stop portion of the door frame when the door is closed. The empty can evacuation weir is provided in the drainage groove provided in the closing operation range in which the door reciprocates on the floor surface, and obliquely right or with respect to the door closing direction from the bottom of the drainage groove. It is characterized by comprising a slope that is inclined obliquely upward to the left.
[0017]
According to this empty can evacuation weir, empty cans existing inside the drainage ditch are excluded as follows.
First, the empty can is pushed and moved toward the door stop portion of the door frame as the door is closed. Then, the empty can comes into contact with a slope that rises obliquely to the right or diagonally left with respect to the direction in which the door closes from the bottom of the drain groove. And when it is pushed further toward the door stop, the empty can starts to climb the slope. Since this slope is inclined upward or diagonally to the right or diagonally left with respect to the direction in which the door closes, the empty can rises along the left or right end of the drainage groove. When pushed further, the empty can escapes from the drainage groove and is removed to the left or right side of the drainage groove with an inclination in the diagonally right or diagonally left direction. That is, it is excluded at a position where it is not sandwiched between the door stop portion of the door frame and the door tip portion of the door.
[0018]
In this way, this empty can evacuation weir can prevent the door from being pinched between the door stop portion and the door end portion even if an obstacle such as an empty can enters the drain groove. The closing operation is not hindered by an empty can or the like.
The empty can evacuation weir described in claim 7 is the empty can evacuation weir described in claim 6, wherein the empty can evacuation weir is provided at a position in the drain groove that does not violate the open / close operation range.
The invention described in claim 8 is the empty can eliminating weir described in claim 6 or 7 , which is applied to a door of an entrance / exit of a railway vehicle.
[0019]
Since empty cans and the like are often left on the passenger compartment floor of a railway vehicle, the effect of the present invention, i.e., the closing of the door, can be achieved by applying the empty can eliminating weir of the present invention to the door of the railway vehicle. The effect that the operation is not hindered by an empty can or the like appears more remarkably.
The empty can evacuation weir described in claim 9 is the empty can evacuation weir described in claim 8, wherein the inclined surface is inclined upward from the bottom of the drainage groove in the direction in which the door is closed, and on the outside of the vehicle. It is characterized by an ascending slope.
In addition, you may use together the empty can exclusion weir in any one of Claim 1 to 3 and the empty can exclusion weir in Claim 6 . In this way, the reliability of empty can removal is further improved as compared with the case where each empty can exclusion weir is provided alone. For this reason, the effect that the closing operation of the door is not hindered by an empty can or the like becomes more remarkable.
[0020]
In particular, in railway vehicles, the empty can exclusion weir described in claim 4 or 5 and the empty can exclusion weir described in claim 8 or claim 9 can be used in combination. In this way, the above-mentioned effect appears more remarkably.
[0021]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described with reference to the drawings.
Here, an example will be described in which the empty can evacuation weir according to the present invention is applied to a door mechanism of a railway vehicle, specifically, a 300 series (Shinkansen Nozomi) vehicle. As the door mechanism, a sliding door system and a plug door system applied to a 300 series vehicle will be taken up. In the first embodiment, the case where the empty can eliminating weir according to the present invention is applied to a sliding door type door mechanism, and in the case of the second embodiment, the case where it is applied to a plug door type door mechanism will be described.
[0022]
[Embodiment 1]
First, the configuration of the empty can exclusion weir 30 of the first embodiment and the sliding door type door mechanism to which the empty can exclusion weir 30 is applied will be described.
FIG. 1 is a plan sectional view of the door mechanism, FIG. 2 is a front sectional view, FIG. 3 is a side sectional view, and FIG. 1 and 3 are diagrams when the door is in a fully closed state, and FIG. 2 is a diagram when the door is in a fully opened state.
[0023]
The door mechanism includes a door 1, a lower rail 5, a door stopper 7, and an empty can exclusion weir 30.
The door 1 reciprocates by air pressure, electromagnetic force, etc., and opens and closes the entrance / exit.
[0024]
The lower rail 5 is provided on the floor surface of the doorway substantially parallel to the traveling direction of the vehicle, and guides the door 1 so that it does not deviate from the track of the opening / closing operation.
Here, the opening / closing operation refers to an operation of reciprocating between a fully closed state in which the door tip portion 3 abuts against the door stop 7 and a fully open state in which the entire door 1 is housed in a door pocket (not shown). .
[0025]
The door stop portion 7 constitutes a part of the door frame 11 and is a portion that comes into contact with the door tip portion 3 when the door 1 is in a fully closed state.
The empty can exclusion weir 30 is for preventing an obstacle such as the empty can 17 from being caught between the door tip portion 3 and the door stop portion 7 of the door 1 when the door 1 is closed. is there. The empty can exclusion weir 30 is formed of stainless steel or aluminum alloy in a substantially triangular pyramid shape, and includes a ridge line 31 that is inclined upward from the floor surface in a direction in which the door 1 is closed. Further, the empty can exclusion weir 30 invades the open / close operation range (in this embodiment, the range sandwiched between the boundary lines 13 and 15) in which the door 1 reciprocates in the floor surface near the door stop 7. No position, specifically the inside of the opening / closing operation range, more specifically, a line projected from the top to the floor surface (corresponding to the side 35 on the bottom surface of the empty can exclusion weir 30 in this embodiment) and the boundary line 13 is provided at such a position that approximately coincides with 13. Further, in order to facilitate attachment to the floor surface, a planar attachment plate 33 is attached to the bottom surface of the empty can exclusion weir 30.
[0026]
Next, the operation of the empty can exclusion weir 30 will be described.
5, 6, 7, 8, and 9 are schematic diagrams illustrating how the empty can 17 is excluded from the open / close operation range by the empty can exclusion weir 30, and FIGS. 5, 6, 8, and 9 are perspective views. 7 and 7 are cross-sectional plan views of FIG.
[0027]
According to the empty can exclusion weir 30, the empty can 17 that has entered the position as shown in FIG. 5 is eliminated as follows. Although only an empty can is described here, the same effect can be obtained with an empty bottle or the like as long as the rotating body has a cylindrical shape or the like. In addition, there are some shapes other than the above that can achieve the same effect.
[0028]
First, the empty can 17 is pushed toward the door stop 7 with the closing operation of the door 1. Then, as shown in FIGS. 6 and 7, the empty can 17 comes into contact with the ridgeline 31 of the empty can exclusion weir 30. When pushed further toward the door stop 7, the empty can 17 tends to ride on the ridge line 31. However, since the empty can 17 has a cylindrical shape, it cannot be ridden on the ridgeline 31 stably. For this reason, as shown in FIG. 8, the empty can 17 falls from the ridgeline 31 to the vehicle interior side. When further pushed from this state, as shown in FIG. 9, the empty can 17 is removed at a position where it is not sandwiched between the door stop portion 7 and the door end portion 3.
[0029]
Next, the effect of this empty can exclusion weir 30 will be described.
(1) As described above, even if an obstacle such as the empty can 17 enters the position as shown in FIG. 5, the empty can exclusion weir 30 is located between the door stop portion 7 and the door end portion 3. Since it can be made not to be pinched, the effect that the closing operation of the door is not hindered by the empty can 17 or the like is exhibited.
[0030]
(2) The ridgeline 31 of the empty can exclusion weir 30 is provided very close to the open / close operation range. Since the ridgeline 31 is provided at such a position, even if the empty can 17 is very small, the axis 19 (center of gravity) of the empty can 17 is located on the vehicle interior side relative to the ridgeline 31 as shown in FIG. Will be located. For this reason, after the empty can 17 rides on the ridgeline 31, the reliability which falls to the direction away from the door 1, ie, a vehicle inside, improves. Therefore, the effect of the present invention, that is, the effect that the closing operation of the door is not hindered by an empty can or the like becomes remarkable.
[0031]
{Circle around (3)} Since this empty can exclusion weir 30 has a substantially triangular pyramid shape, it is very easy to install and exhibits the effect that excellent stability can be obtained after installation. {Circle around (4)} Since the empty can eliminating weir 30 is not complicated, it exhibits an effect that it can be easily manufactured.
[0032]
(5) Since the empty can exclusion weir 30 is provided inside the vehicle in the opening / closing operation range, the empty can 17 is excluded from the ridgeline 31 to the inside of the vehicle. Therefore, the useful effect of not polluting the outside of the vehicle, that is, the track is exhibited.
(6) Since the empty can evacuation weir 30 is provided in the vicinity of the door stop 7, it is further useful that the probability of the empty can 17 entering the vicinity of the door stop 7 in the open / close operation range can be reduced. Exerts a positive effect.
[0033]
Since the effects as described above are obtained, it is possible to avoid a situation in which the closing operation of the door is hindered by an obstacle such as an empty can, the departure time of the railway vehicle is delayed, and the schedule is disturbed.
[Embodiment 2]
First, the configuration of the empty can exclusion weirs 30 and 40 of the second embodiment and the plug door type door mechanism to which these empty can exclusion weirs 30 and 40 are applied will be described.
[0034]
10 is a plan sectional view of the door mechanism, FIG. 11 is a front sectional view, FIG. 12 is a side sectional view, and FIG. 13 is a perspective view of an empty can removing weir 40. 10 and 11 are views when the door is in the fully open state, and FIG. 12 is a view collectively showing the fully open and fully closed states. This door mechanism includes a door 1, a drainage groove 9, an empty can exclusion weir 30, and an empty can exclusion weir 40.
[0035]
Since the door 1 is the same as that of the above-mentioned Embodiment 1, description is abbreviate | omitted.
The drainage groove 9 is a groove for discharging water drops or the like that have fallen from the user's rain gear to the floor surface, and is provided in the opening / closing operation range of the door 1 in the floor surface.
The empty can exclusion weir 30 is the same as that of the first embodiment, and is provided at a position hidden behind the door frame 11 when viewed from the outside of the vehicle as shown in FIG.
[0036]
As with the empty can exclusion weir 30, the empty can exclusion weir 40 is configured such that when the door 1 is closed, an obstacle such as the empty can 17 is not sandwiched between the door tip portion 3 and the door stop portion 7. It is for making. The empty can evacuation weir 40 is provided inside the drainage groove 9, and includes a slope 41 that rises from the bottom of the drainage groove 9 in the direction in which the door 1 closes and rises to the outside of the vehicle.
[0037]
Moreover, the empty can exclusion weir 40 is formed so that the cross-sectional shape by a plane orthogonal to the longitudinal direction is substantially trapezoidal. Further, the width W1 of the upper bottom surface 43 of the empty can exclusion weir 40 is set to be slightly narrower than the opening width W3 of the drainage groove 9. Similarly, the width W2 of the lower bottom surface 45 is the bottom width of the drainage groove 9. It is set slightly narrower than W4. This is because the drainage effect of the drainage groove 9 is favorably maintained by securing a gap for water drops or the like on the floor surface to flow into the drainage groove 9.
[0038]
Here, the opening / closing operation performed by the plug door type door mechanism will be described.
First, like the sliding door system, the door 1 moves substantially linearly in the traveling direction of the train or in the opposite direction. At this time, the door 1 passes substantially directly above the drainage groove 9. When the door 1 is displaced along the direction of the closing operation to a predetermined position, the door 1 moves along the direction of the closing operation while moving from the vehicle inner side position (the left side position indicated by the solid line in FIG. 12) to the vehicle outer side. To the position (the position on the right side indicated by the alternate long and short dash line in FIG. 12) to reach the fully closed state. In addition, this plug door system reduces the air resistance at the time of driving | running | working by comprising so that the outer surface of a vehicle and the outer surface of the door 1 may be located on the substantially same plane in the state which the door 1 closed, This is a method applied for the purpose of making the appearance of a vehicle orderly with no irregularities.
[0039]
Next, the effect | action of these empty can exclusion weirs 30 and 40 is demonstrated.
FIGS. 14, 15, 16, and 17 are schematic perspective views illustrating a state in which the empty can 17 is excluded from the drainage groove 9 by the empty can exclusion weir 40.
According to the empty can exclusion weir 40, the empty can 17 that has entered the position shown in FIG. 14 is eliminated as follows. As in the first embodiment, only an empty can is described here, but a similar effect can be obtained with an empty bottle or the like as long as the rotating body has a cylindrical shape or the like. In addition, there are some shapes other than the above that can achieve the same effect.
[0040]
First, the empty can 17 is pushed and moved in the drain groove 9 in the direction in which the door 1 is closed in accordance with the closing operation of the door 1. Then, as shown in FIG. 15, the empty can 17 contacts the slope 41 of the empty can exclusion weir 40. When the door 1 is further pushed in the closing direction, the empty can 17 starts to climb the slope 41. Since the slope 41 is inclined upward toward the vehicle exterior, the empty can 17 receives a force toward the vehicle interior due to the downward component of the slope 41 of gravity. For this reason, as shown in FIG. 16, the empty can 17 climbs the slope 41 while being in contact with the inner edge of the drainage groove 9. And if it pushes further from this state, the empty can 17 will climb the slope 41 completely. Then, as shown in FIG. 17, the empty can 17 is removed from the drainage groove 9 to the inside of the vehicle by the force applied to the inside of the vehicle that has been received until then.
[0041]
Then, the empty can 17 removed from the drainage groove 9 is further eliminated to the inside of the vehicle by an action similar to that of the first embodiment by the empty can exclusion weir 30 provided along the drainage groove 9.
Next, the effect of these empty can exclusion weirs 30 and 40 will be described.
[0042]
According to the above empty can exclusion weir 40, the effects (1) to (6) can be obtained as in the first embodiment, and the disturbance of the diamond can be avoided. Furthermore, the empty can exclusion weir 30 of the second embodiment is provided at a position hidden behind the door frame 11 when viewed from the outside of the vehicle. Therefore, there is a more useful effect that there is no possibility of impairing the orderly appearance in the vehicle without being obstructive.
[0043]
Moreover, since the reliability of removing the empty can 17 is further improved by using the empty can eliminating weirs 30 and 40 together, the effect that the closing operation of the door 1 is not hindered by the empty can 17 is further remarkable. It becomes.
While the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and may be implemented in various modes.
[0044]
For example, in the above-described embodiment, the case of being attached to the floor surface of a railway vehicle has been described as an example. However, in the scope of the present invention, it may be attached to a vehicle or a place other than the railway vehicle.
