Description

{DOORWAY DEVICE FOR ELEVATOR}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a doorway device for a car or a platform of an elevator, and more particularly to an elevator doorway device in which a groove of a door for guiding opening and closing of a door is opened downward.

An example of a conventional entrance / exit device of an elevator will be described with reference to the drawings. Fig. 9 is a side view showing a state in which the car of the elevator is mounted on the platform, and Fig. 10 is a sectional view of the vicinity of the platform threshold. In the drawings, reference numeral 1 denotes a platform, reference numeral 2 denotes a platform door, and reference numeral 3 denotes a rail fixed to a building wall. The landing door 2 is suspended on the rail 3 by a roller 4 of a door hanger 5 provided on the upper portion of the landing door 2. Reference numeral 6 denotes a guide provided at the lower end of the landing door 2. [ The guide 6 is coupled to the groove 10 of the threshold 7 provided on the fixed portion 9 of the landing platform 1. Reference numeral 11 is a protection plate for preventing the tip of a person who is riding on the car 8 from getting caught in the gap between the threshold 7 and the fixed portion 9 or falling into the hoistway. The protection plate provided on the landing platform 1 is called a tow guard or a face plate, and the protection plate provided on the car 8 is called an apron.

The car 8 is connected to the car door 2a, the rail 3a, the roller 4a, the door hanger 5a, the guide 6a, the threshold 7a, the shield plate (apron) 11a. Reference numeral 12 denotes a main rope suspending the car 8.

In this case, since the groove of the threshold is opened upward, there is a problem that garbage and dust enter the groove and interfere with the opening and closing of the door, and it is also not preferable in terms of design.

Therefore, it is conceivable that the groove is opened to the lower side of the threshold. 11 is a front view of the landing door and the threshold, and Fig. 12 is a sectional view taken along line A-A of Fig. In the figure, reference numeral 13 denotes a groove opened below the threshold 7. Reference numeral 14 denotes a guide provided at the lower end of the landing door 2. [ The guide 14 is composed of a guide piece 15 that engages with the groove 13 and a support member 16 that fixes the guide piece 15 to the lower end of the landing door 2. The same reference numerals as those in Fig. 10 denote the same elements. The threshold on the side of the car 8 is also the same.

When the guide 14 is installed on the landing door 2, the gap S0 between the lower end 7b of the threshold 7 side (the right side in Fig. 12) and the upper end of the protective plate 11, (15) is inserted into the groove (13). Then, a support member 16 is provided at the lower end of the landing door 2.

With this configuration, no dust or dust enters the groove 13, and it is also preferable for the design.

Japanese Utility Model Application Publication No. 60-137774

In the above-described configuration, the gap S0 becomes larger to insert the guide piece 15 from the gap SO. Therefore, when the car 8 is conceived on the landing platform 1 by the expansion and contraction of the main rope 12 due to the reel bearing of the car 8, that is, the load on the car 8, The foot of the user may be caught in the gap S0 when the car 8 is lowered and lowered in a state in which the car door 2a is opened when a step is formed between the foot 7a and the threshold 7a .

It is also conceivable to insert the guide 14 into the gap SO from the end of the opening of the protective plate 11 (the left and right direction in Fig. 11), not from the gap SO. However, since the length of the protective plate 11 in the opening direction is longer than the width of the doorway, there is a problem that it is difficult to attach and detach the guide 14.

The present invention relates to an elevator, comprising: a threshold disposed below a door of an elevator and opening to open and close the door, the elevation being opened to the downward direction; And a protection plate provided at a side of a hoistway of the fixing unit at an interval in a downward direction from the threshold, wherein the protection plate is vertically adjustable in position , And the upper portion thereof is a guard for adjusting the clearance between the threshold and the protection plate.

Thus, since the position of the protection plate can be adjusted, the gap between the threshold and the protection plate can be made small, and the toe of the user can be prevented from getting caught in the gap.

Further, in the present invention, the guard of the protection plate is separable from the portion other than the guard of the protection plate, and the position of the guard is adjustable in the vertical direction.

As a result, the guard can be made smaller and lighter, so that the clearance between the threshold and the shield plate can be easily adjusted. It is also possible to use a bending material or a shape material of a steel sheet as a guard.

According to another aspect of the present invention, there is provided an elevator including a door disposed below a door of an elevator and opening to open and close the door, the door opening downward, And a protection plate provided on a side of a hoistway of the fixing unit at an interval in a downward direction from the threshold, the elevator doorway apparatus comprising: A guard for adjusting the clearance of the airbag is installed.

Thereby, the guard can be easily installed.

Further, the present invention is provided with a spacer for fixing the guard and the threshold at a position outside the range where the guide moves during opening and closing of the door.

Thus, since the strength of the guard can be increased, warpage of the guard can be prevented, and the gap between the threshold and the protection plate can be prevented from widening.

Further, in the present invention, the surface of the threshold portion on the hoistway side is an inclined surface protruding upward from the lower side toward the hoistway.

Thus, even when the toe is inserted into the gap between the threshold and the protection plate, the toe can be extruded toward the hoistway along the inclined surface with the elevation of the car.

In addition, the guard has a cross-sectional shape of "U" shape in which the middle portion in the vertical direction protrudes toward the hoistway.

This makes it difficult for the toe to be caught in the gap.

Further, the guard has a curved portion in its middle portion, and the tip end of the bent portion protrudes toward the hoistway side than the end surface on the hoistway side of the threshold.

This makes it difficult for the toe to be caught in the gap.

Further, the upper end of the guard is disposed so as to coincide with the end surface of the threshold on the side of the hoistway, on the side of the half hoistway or the flat surface than the side surface of the hoistway of the threshold.

As a result, it is difficult for the toe to be caught in the gap, and dust and dust are less likely to enter the threshold groove.

Further, the upper end of the guard has a bent portion, and the tip of the bent portion is disposed so as to coincide with the end surface of the threshold on the side of the hoistway in the half-hoistway side or the flat end surface than the side surface of the hoistway side of the threshold.

As a result, it is difficult for the toe to be caught in the gap, and dust and dust are less likely to enter the threshold groove.

According to another aspect of the present invention, there is provided an elevator including a door disposed below a door of an elevator and opening to open and close the door, the door opening downward, And a protection plate provided on a side of a hoistway of the fixing unit at an interval in a downward direction from the threshold, the upper portion of the protection plate is provided with an opening And a spacer for fixing the guard and the threshold is provided at a position outside the range where the guide moves during opening and closing of the door.

Thus, since the strength of the guard can be increased, warpage of the guard can be prevented, and the gap between the threshold and the protection plate can be prevented from widening.

The door is provided below the door of the elevator and opened to open and close the door. The fixed portion of the lift or car installed with the threshold and the front end of the door are provided in the groove. And a protection plate provided at a side of the elevating passage of the fixing section at an interval in a downward direction from the threshold, wherein an upper portion of the protecting plate has a gap between the threshold and the protecting plate And the guard has a cross-sectional shape of "U" shape in which the middle portion in the vertical direction protrudes toward the hoistway.

This makes it difficult for the toe to be caught in the gap between the threshold and the protective plate.

According to another aspect of the present invention, there is provided an elevator including: a door disposed below a door of an elevator and guiding opening and closing of the door; a wall constituting the groove of the threshold; A guide installed in a door and coupled to the groove to guide opening and closing of the door and a protection plate provided on a side of a hoistway of the fixing unit with an interval downward from the threshold, And a guard provided at a position near the groove of the threshold, and the end of the guard is provided at a position near the lower end of the wall portion constituting the groove of the threshold.

The upper end of the guard may be arranged to coincide with the lower end face of the wall portion constituting the groove of the threshold in the vertical direction.

As a result, it is difficult for the toe to be caught in the gap, and dust and dust are less likely to enter the threshold groove.

The upper end of the guard may be disposed above the lower end surface of the wall portion constituting the groove of the threshold.

As a result, it is difficult for the toe to be caught in the gap, and dust and dust are less likely to enter the threshold groove.

According to the present invention, it is possible to make it difficult for the toe to be caught in the gap between the lower end of the end portion on the hoistway side of the threshold and the upper end portion of the protection plate.

An embodiment of the present invention will be described with reference to Fig. Fig. 1 corresponds to Fig. 12, and the same reference numerals as those in Fig. 12 denote the same elements.

In the figure, reference numeral 20 denotes a guard having a vertically long hole (not shown). The guard 20 is attached to the fixing portion 9 by the bolt 21 through the elongated hole. This makes it possible to adjust the gap S1 between the lower end 22a of the threshold 22 and the upper end 20a of the guard 20 by using the long hole. Reference numeral 22b denotes an end surface of the threshold 22 on the hoistway side. Reference numeral 23 denotes a support fixed to the lower portion of the landing door 2. [ Reference numeral 24 denotes a guide. The guide 24 has a guide piece 25 to be engaged with the groove 13 of the threshold 22 and a support member 26 for fixing the guide piece 25 to the support 23. Reference numeral 27 denotes a shim for adjusting the amount of projection of the support member 26 to the hoistway side (right side in Fig. 1). Reference numeral 28 denotes a reinforcing member of the guard 20.

When the guide 24 is provided, the guide piece 25 is engaged with the groove 13, and the support member 26 is fixed to the support 23. Next, the guard 20 is attached to the fixing portion 9 by means of the bolt 21. At this time, the gap S1 is set to be optimal by using the long hole of the guard 20. [ When the guide 24 is removed, the reverse procedure is performed.

Thus, since the optimum gap S1 can be set by a simple operation, the possibility that the user's foot is caught in the gap S1 can be reduced. In this embodiment, the upper end 20a of the guard 20 is located on the half-hoist side (left side in Fig. 1) of the threshold 22 side than the hoistway side end face 22b, There is an effect that it is difficult to enter. Further, since the guard 20 is provided with the reinforcing member 28, it is possible to prevent the guard 20 from being deformed even if the user's foot is hit.

In this embodiment, the guard 20 is movable upward only because the reinforcing member 28 has an L-shaped cross section. However, the guard 20 may be formed with a long hole, and the reinforcing member 28 So that the position of the guard 20 in both the upper and lower directions can be adjusted. Further, the position of the guard 20 in both the upper and lower directions can be adjusted by changing the shape of the stiffener or omitting the stiffener to increase the strength of the guard 20 itself.

As shown in Fig. 1, the groove 13 is formed between two wall portions 16 and 17 formed in the threshold 22. In Fig. One of the two wall portions 16 and 17 located on the hoistway side is referred to as a first wall portion 16 and the other wall portion located on the half hoistway side is referred to as a second wall portion 17. [ The first wall portion 16 and the second wall portion 17 protrude downward.

The lower end face 16a of the first wall portion 16 is located above the lower end face 17a of the second wall portion 17 as shown in Fig. The upper end portion 20a of the guard 20 is provided in the vicinity of the first wall portion 16 but is located above the lower end face 16a of the first wall portion 16. The guard 20 is overlapped with the first wall portion 16 in the vertical direction.

Fig. 2 shows another embodiment of the present invention. In this embodiment, a part or all of the end surface 22b on the hoistway side of the threshold 22 is inclined to form a hoistway surface 22c. The upper portion 30a of the guard 30 is also inclined so as to be parallel to the hoistway side face 22c and the tip end thereof is aligned with the hoistway side end face 22b of the threshold 22 It is. In addition, the support member 26a of the guide 24 is inclined in accordance with the inclination. Otherwise, it is the same as in Fig.

Even if the user's toes hit the upper surface 30a of the guard 30 or the hoistway surface 22c of the threshold 22 when the car 8 is slowed up, 2), the possibility of being caught in the gap S1 is further lowered.

The upper end portion 30a of the guard 30 is provided at a position substantially coinciding with the lower end face 16a of the first wall portion 16 constituting the groove 13 in the vertical direction have.

Fig. 3 shows another embodiment of the present invention. The upper end of the guard 40 is curved in a U-shaped cross section and the tip of the hoistway side (the right side in Fig. 3) of the middle portion 41 is curved in a direction of the hoistway side end face 22b of the threshold 22 And are formed in a matching shape. The upper side 42 of the intermediate portion 41 is inclined upward and the lower side surface 43 is inclined downward. The reinforcing member 44 also has a shape conforming to the above-described shape. Otherwise, it is the same as in Fig.

With this configuration, since the tip (upper end) of the guard 40 is introduced to the half-hoistway side, the possibility that the toe of the user is caught on the tip of the guard is lowered. In addition, there is an effect that it is easy to remove even if the guard of the user is caught by the toe of the user.

In this embodiment as well, as in the embodiment of Figs. 1 and 2, the guard 40 is movable upward only because of the presence of the stiffener 44, but the shape of the stiffener may be changed or the stiffener may be omitted, By increasing the strength of itself, it is possible to move the guard in both the up and down directions.

Further, as shown in Fig. 3, the guard 40 is formed by bending the middle part and the upper part. Further, the lower portion of the guard 40 is not bent, but is formed in a straight line when viewed from the end face. The curved portion of the middle portion of the guard 40 is referred to as a first bend portion 40a and the bent portion of the upper end is referred to as a second bend portion 40b and the portion of the straight line below the guard 40 is referred to as a straight portion 40c ).

The first bent portion 40a has a portion 45 integrally formed with the straight portion 45 and a portion integrally formed with the first piece 45 (Hereinafter referred to as " a "). The first bent portion 40a is configured to protrude toward the hoistway. More specifically, the first bend section 40a is disposed so as to substantially coincide with the hoistway side end face 22b of the threshold 22 in the transverse direction (direction perpendicular to the up-and-down direction, left-right direction in the figure) have. That is, the first bend section 40a is disposed so that the straight line or plane contacting the first bend section 40a and the end surface 22b of the threshold 22 in parallel with the up / down direction (vertical direction) .

The second bent portion 40b is formed between the above-described second piece 46 and a portion integrally formed with the second piece 46 (hereinafter referred to as "third piece") 47. The second bent portion 40b is formed to protrude upward. The second bend section 40b is provided on the half-hoist side of the step 22 side end surface 22b in the transverse direction. In other words, the end surface 22b of the threshold 22 on the hoistway side is located closer to the hoistway than the tip of the second bent portion 40b in the transverse direction. The third piece (47) constituting the second bent portion (40b) is directed downward in the inclined downward direction on the semi-hoisted river side.

It is preferable that the tip end of the second bent portion 40b is arranged to substantially coincide with the lower end face 16a of the first wall portion 16 constituting the groove 13 in the vertical direction. It is more preferable that the tip end of the second bent portion 40b is disposed above the lower end face 16a of the first wall portion 16 in the up and down direction. Thus, it is possible to prevent the user's foot from entering between the first wall portion 16 and the second bent portion 40b.

The second bent portion 40b is a convex portion protruding upward and has a concave portion 48 between the second piece 46 and the third piece 47 because the guard 40 is formed in a plate shape. One end of the reinforcing member 44 is inserted into the concave portion 48. One end of the reinforcing member 44 is inserted into the concave portion 48 of the second bent portion 40b to thereby support the guard 40. [

The linear portion 40c has a through hole with respect to its thickness direction. The through hole is formed as a long hole along the vertical direction. A through hole is also formed in the protective plate 11. The through hole of the straight portion 40c and the through hole of the shield plate 11 are made to coincide with each other so that the shaft portion of the bolt 21 is inserted therethrough and the shaft portion of the bolt 21 is screwed into the screw The guard 40 is fixed to the threshold 22 by screwing it into the hole. Since the through hole of the straight portion 40c is formed long in the vertical direction, the position can be adjusted in the vertical direction.

The through hole of the straight portion 40c may not be formed as a long hole but may be formed in a circular shape. That is, for example, the tip end of the second bent portion 40b of the guard 40 substantially coincides with the lower end face 16a of the first wall portion 16 constituting the groove 13 of the threshold 22, Even if the through hole of the straight portion 40c is not formed as an elongated hole, it is possible to adjust the position of the guard 40 in the optimum position without adjusting the position in the vertical direction It becomes possible to arrange it.

The guard 40 having the first bend section 40a, the second bend section 40b and the straight line section 40c may be formed by bending a metal plate or by extrusion molding. Further, the guard 40 may be formed of a synthetic resin.

In the above embodiments, the reinforcing member is attached to the upper part of the guard or the strength of the guard itself is increased. However, since the length of the guard in the opening direction is longer than the width of the entrance, It may be desired to further increase the strength of the upper portion of the guard to maintain the clearance S1 over the entire opening direction.

Therefore, an embodiment in which the strength of the guard is increased will be described with reference to Fig.

4 shows a spacer 50 provided between the upper surface 30a of the guard 30 and the surface 22c of the side surface of the threshold 22 shown in Fig. Since the upper portion 30a is fixed to the hoistway side surface 22c by the spacer 50, the strength of the guard 30 can be increased, and the gap S1 can be stably maintained. The spacer 50 is provided at a position other than the range in which the guide 24 moves during the opening and closing operation of the door 2, that is, at the center of the central double wishbone door and at both ends of the threshold 22.

Since the gap S1 is adjustable, the thickness of the spacer 50 can be adjusted by using a core or the like in accordance with the gap S1.

Fig. 5 shows another embodiment of the present invention. In this embodiment, the guard 51 has a straight portion 51c at a lower portion thereof. The straight portion 51c has a through hole (long hole) that penetrates in the thickness direction and is long in the vertical direction. The straight portion 51c is fixed to the protection plate 11 through the through hole and the bolt 21. [ The upper portion of the guard 51 is formed to be thicker than the thickness of the straight portion 51c. The outer surface of the upper portion of the guard 51 is formed at the same height as the outer surface of the straight portion 51c. The inner surface of the guard (51) has an inclined surface (51a) inclined at a predetermined angle with respect to the outer surface of the guard (51). Since the upper portion of the guard 51 is formed thicker than the straight portion 51c, the strength is high. Therefore, it is possible to secure sufficient strength of the guard 51 without using the reinforcing members 28, 44 in the above-described other embodiment.

Fig. 6 shows another embodiment of the present invention. In the present embodiment, the guard 60 has a straight portion 60c fixed to the protection plate 11. [ The linear portion 60c has a through hole (long hole) that penetrates in the thickness direction and is long in the vertical direction. The straight portion 60c is fixed to the protection plate 11 through the through hole and the bolt 21. [ A wall portion 62 protruding toward the hoistway is formed around the straight portion 60c. By forming the wall portion 62 around the straight portion 60c in this way, the strength of the guard 60 can be increased. Therefore, it is possible to secure a sufficient strength of the guard 60 without using the reinforcing members 28, 44 in the other embodiment described above.

The upper portion of the guard 60 is configured to be tapered toward the upper side. The outer surface of the guard 60 is formed at the same height as the end surface 62a of the wall portion 62 formed around the straight portion 60c. The inner surface of the guard 60 has an inclined surface 60d inclined at a predetermined angle with respect to the outer surface of the guard 60. [

The upper end portion 60a of the guard 60 is located above the lower end face 16a of the second wall portion 17 constituting the groove 13 of the threshold 22 in the vertical direction.

7 and 8 show another embodiment of the present invention. In this embodiment, the shield plate 11 has a guard 70, a shield plate main body 11a, a guard 70, and a support plate 18 for supporting the shield plate main body 11a. The support plate 18 supports the guard 70 in a position away from the shield plate main body 11a. The support plate 18 includes a linear portion 18a extending linearly in the vertical direction, an inclined portion 18b extending obliquely at a predetermined angle with respect to the linear portion 18a, a support portion 18c.

The linear portion 18a is a supporting portion for supporting the shield plate main body 11a. The linear portion 18a supports the shield plate main body 11a through the bolts 21. [ The inclined portion 18b is a supporting portion for supporting the guard 70. [ The inclined portion 18b supports the guard 70 through the bolt 72. [ The support 18c is connected to the threshold 22 via bolts 73 and nuts 74. [

The guard 70 has a triangular shape when viewed from the side. The guard 70 has a straight portion 70c detachably attached to the inclined portion 18b of the support plate 18. [ The linear portion 70c has a through hole 19 that penetrates in the thickness direction and is long in the up and down direction. The linear portion 70c is fixed to the inclined portion 18b of the support plate 18 by the through hole 19 and the bolt 72. [ A wall portion 76 protruding toward the hoistway is formed around the straight portion 70c.

As shown in Fig. 7, the upper portion of the guard 70 is configured to be tapered toward the upper side. The upper end 70a of the guard 70 is located above the lower end face 16a of the first wall portion 16 constituting the groove 13 of the threshold 22. [

Since the through hole 19 is formed in the linear portion 70c of the guard 70, the bolt 72 for fixing the guard 70 can be loosened and moved downward. The guide piece 25 can be removed from the groove 13 of the threshold 22 by moving the guide 24 downward when the guard 70 is moved downward as shown in Fig.

In each of the above embodiments, the upper end portion of the guard does not protrude more toward the hoistway than the threshold, so that dust, dust, and the like can be prevented from entering the gap. Even when an external force is applied to the door from the landing side to the hoistway side, the gap between the threshold and the guard can be made small, so that the effect of preventing the guide from falling off toward the hoistingway side The guide is difficult to deviate from the conventional configuration.

In the above embodiments, the protection plate 11 is fixed sufficiently below the threshold 22, and the guards 20, 30, and 40 are installed above the protection plate 11 so as to overlap with the protection plate 11 A cutout portion through which the guide 24 can pass is formed in a part of the protection plate 11 and the guide 24 is installed on the door 2 by using the cutout portion, A structure in which a position adjustable guard is provided may be employed. In this case, the upper end portion of the protective plate 11 and the lower end portion of the threshold 22 are set as the gap S1.

With such a configuration, the size and weight of the guard can be reduced, so that the installation and adjustment of the guard can be facilitated.

When the guards 20, 30 and 40 are mounted on the fixing part 9, the guards 20, 30 and 40 may be overlapped with the protective plate 11, Even if there is a clearance between the cover 11 and the cover 11, the toe is not caught by the fixing portion 9. [ Further, the guards 20, 30, 40 may be formed integrally with the protective plate 11. By doing so, the number of parts can be reduced.
