Description

Technical Field

[0001] The present invention relates to a door sill and an elevator including the door sill.

Background Art

[0002] An elevator car is provided with an opening through which people and luggage enter and exit, and a car door that opens and closes the opening. On the other hand, each floor of a building structure is provided with an entrance / exit facing the opening of the car and a landing door that opens and closes the entrance / exit. A door sill (threshold) is provided at the opening of the car and the entrance / exit of the building structure. The door sill has a sill groove that guides the movement of the door in the opening and closing direction.

[0003] In recent years, it has been required to narrow the width of the sill groove so that the front wheels of a wheelchair do not enter the sill groove. Also, the width of the sill groove may be changed according to the standards of a country or region. Therefore, there are cases where the door sill of an already installed elevator is replaced with a new door sill having a different sill groove width.

[0004] Patent Document 1 describes a threshold (door sill) that guides the leg portion of a door of a door opening / closing device used in an elevator. The threshold described in this Patent Document 1 has a plurality of long threshold bodies having a U-shaped cross section and a plurality of short spacers having a width corresponding to the sill groove width.

Summary of the Invention

Problems to be Solved by the Invention

[0006] By the way, in the threshold (door sill) described in Patent Document 1, it is possible to change the width of the threshold groove by changing the width of the spacer. However, when the width of the spacer is changed, the width of the entire threshold is changed. Therefore, it is necessary to remove the spacer and the threshold body from the building structure and attach a new threshold. Therefore, when changing the width of the threshold groove, the same work as when replacing the integrally formed threshold is required.

[0007] An object of the present invention is to provide a door sill and an elevator that can improve workability when changing the width of a sill groove in consideration of the above problems.

Means for Solving the Problems

[0008] In order to solve the above problems and achieve the object of the present invention, the door sill of the present invention includes a receiving portion, a first sill groove forming portion, and a second sill groove forming portion. The receiving portion is fixed to the entrance of an elevator provided in a building structure. The first sill groove forming portion is fixed to the receiving portion and forms the first wall surface of the sill groove. The second sill groove forming portion is detachably fixed to the receiving portion and forms the second wall surface of the sill groove. The first fin groove forming portion has a bottom surface portion that forms the bottom of the fin groove, a first groove wall surface portion that continuously forms the first wall portion of the fin groove on the bottom surface portion, and a first upper surface portion that is substantially orthogonal to the first groove wall surface portion. The second fin groove forming portion has a second groove wall surface portion that forms the second wall portion of the fin groove and a second upper surface portion that is substantially orthogonal to the second groove wall surface portion. The second fin groove forming portion has a second groove wall surface portion that forms the second wall portion of the fin groove and a second upper surface portion that is substantially orthogonal to the second groove wall surface portion. The second groove wall surface portion has an end surface on the side opposite to the second upper surface portion, and the end surface of the second groove wall surface portion abuts against the bottom surface portion of the first fin groove forming portion.

[0009] Further, the elevator of the present invention includes a car that moves up and down in an elevator shaft provided in a building structure and stops at a position facing the entrance provided on each floor of the building structure, and the above-described door sill attached to the entrance.

Also, the width direction is parallel to the moving direction of the car-side door 125. Fixed brackets 135A, 135B are fixed to the front columns 123a, 123a.

[0025] The fixed bracket 135A is fixed to the front column 123a arranged at one end in the width direction of the car 120 among the two front columns 123a, 123a. Also, the fixed bracket 135B is fixed to the front column 123a arranged at the other end in the width direction of the car 120 among the two front columns 123a, 123a.

[0026] [Configuration of Door Sill] Next, the configuration of the building-side door sill 206 will be described with reference to Figs. 3 and 4. Fig. 4 is a side view showing the building-side door sill 206.

[0027] As shown in FIG. 3, the building-side door sill 206 is a long member. The longitudinal direction of the building-side door sill 206 is the direction in which the building-side door 205 moves, and the width direction of the building-side door sill 206 is the direction in which the building-side door 205 and the car-side door 125 face each other. The building-side door sill 206 has a sill groove 206a extending in the longitudinal direction. The lower end portion of the building-side door 205 is slidably engaged with the sill groove 206a. The sill groove 206a guides the movement of the building-side door 205.

[0028] As shown in FIG. 4, the building-side door sill 206 has a receiving portion 210 fixed to an entrance 201a (see FIG. 1) provided in a building structure, a first sill groove forming portion 220 connected to the receiving portion 210, and a second sill groove forming portion 230 detachably connected to the receiving portion 210.

[0029] The receiving portion 210 is formed by bending a sheet metal.

[0030] The first support portion 211 is formed of a rectangular plate body having a plane substantially perpendicular to the vertical direction. The length of the short side of the first support portion 211 is substantially the same as the length in the width direction of the building-side door sill 206, and the length of the long side of the first support portion 211 is substantially the same as the length in the longitudinal direction of the building-side door sill 206. The first support portion 211 is fixed to the lower end portion of the entrance 201a via a bracket (not shown). Also, the upper surface of the first support portion 211 supports the first sill groove forming portion 220.

[0031] The wall plate portion 212 is continuous with the long side on the car-door side in the first support portion 211 and protrudes downward. The wall plate portion 212 is formed of a rectangular plate body having a plane substantially perpendicular to the direction in which the building-side door 205 and the car-side door 125 face each other. The wall plate portion 213 is continuous with the long side on the building-structure side in the first support portion 211 and protrudes upward. The wall plate portion 213 is formed of a rectangular plate body having a plane substantially perpendicular to the direction in which the building-side door 205 and the car-side door 125 face each other.

[0032] The second support portion 214 is continuous with the wall plate portion 213 and protrudes in the horizontal direction. The second support portion 214 is composed of a rectangular plate body having a plane substantially perpendicular to the vertical direction. The lower surface of the second support portion 214 faces the upper surface of the first support portion 211 with a predetermined distance therebetween. The upper surface of the second support portion 214 supports the second sill groove forming portion 230.

[0033] The first sill groove forming portion 220 has a base 240 fixed to the receiving portion 210 and a surface material 250 joined to the base 240. The surface material 250 forms the appearance surface of the first sill groove forming portion 220.

[0034] The base 240 is formed by bending a sheet metal having the same thickness as the receiving portion 210. The base 240 is formed of, for example, a stainless steel plate.

[0035] The base 240 has a first supported portion 241, a wall plate portion 242 that intersects the first supported portion 241 substantially perpendicularly, and a horizontal plate portion 243 that intersects the wall plate portion 242 substantially perpendicularly. Further, the base 240 has a groove wall portion 244 that intersects the horizontal plate portion 243 substantially perpendicularly and a second supported portion 245 that intersects the groove wall portion 244 substantially perpendicularly.

[0036] The first supported portion 241 is composed of a rectangular plate body having a plane substantially perpendicular to the downward direction. The first supported portion 241 is supported by the first support portion 211 of the receiving portion 210. Also, the first supported portion 241 is fixed to the first support portion 211 using screws.

[0037] The wall plate portion 242 is continuous with the long side on the cage door side of the first supported portion 241 and protrudes upward. The wall plate portion 242 is located above the wall plate portion 212 of the receiving portion 210. The wall plate portion 242 is composed of a rectangular plate body having a plane substantially perpendicular to the direction in which the building side door 205 and the cage side door 125 face each other.

[0038] The horizontal plate portion 243 corresponds to the first upper surface portion according to the present invention. The horizontal plate portion 243 is continuous with the wall plate portion 242 and protrudes toward the building structure side. The horizontal plate portion 243 is composed of a rectangular plate body having a plane substantially perpendicular to the vertical direction. The lower surface of the horizontal plate portion 243 faces the upper surface of the first supported portion 241 with an appropriate distance therebetween. Also, the upper surface of the horizontal plate portion 243 is located at the same height as the upper surface of the second support portion 214 in the receiving portion 210.

[0039] The groove wall portion 244 corresponds to the first groove wall surface portion according to the present invention. The groove wall portion 244 forms the first wall portion of the sill groove 206a. The groove wall portion 244 is continuous with the horizontal plate portion 243 and protrudes downward. The groove wall portion 244 is composed of a rectangular plate body having a plane substantially perpendicular to the direction in which the building side door 205 and the car side door 125 face each other. The groove wall portion 244 faces the wall plate portion 242 with a predetermined distance therebetween in the direction in which the building side door 205 and the car side door 125 face each other.

[0040] The second supported portion 245 corresponds to the bottom surface portion according to the present invention. The second supported portion 245 forms the bottom of the sill groove 206a. The second supported portion 245 is continuous with the groove wall portion 244 and protrudes toward the building structure side. The second supported portion 245 is composed of a rectangular plate body having a plane substantially perpendicular to the vertical direction. A part of the second supported portion 245 faces the second support portion 214 of the receiving portion 210 with an appropriate distance therebetween. The second supported portion 245 is supported by the first support portion 211 of the receiving portion 210.

[0041] The surface material 250 is formed by bending a sheet metal thinner than the base 240 and the receiving portion 210. The surface material 250 is formed of, for example, a stainless steel plate.

[0042] The surface material 250 has a side surface portion 251 facing the wall plate portion 242, an upper surface portion 252 facing the horizontal plate portion 243, a groove wall surface portion 253 facing the groove wall portion 244, a bottom surface portion 254 facing the second supported portion 245, and a rising portion 255. The surface material 250 is joined to the base 240 using, for example, an adhesive.

[0043] The side surface portion 251 forms the side surface on the car door side of the building-side door sill 206. The upper surface portion 252 is continuous with the side surface portion 251 and protrudes toward the building structure side. The upper surface portion 252 forms the upper surface of the building-side door sill 206. The groove wall surface portion 253 is continuous with the upper surface portion 252 and protrudes downward. The groove wall surface portion 253 forms the wall surface of the sill groove 206a. The bottom surface portion 254 is continuous with the groove wall surface portion 253 and protrudes toward the building structure side. The bottom surface portion 254 forms the bottom surface of the sill groove 206a.

[0044] The rising portion 255 of the facing material 250 protrudes upward continuously from the bottom surface portion 254. The rising portion 255 faces the groove wall surface portion 253 in the direction in which the building-side door 205 and the car-side door 125 face each other. The surface of the rising portion 255 facing the groove wall surface portion 253 and the end surface of the second support portion 214 in the receiving portion 210 are located on the same virtual plane. The rising portion 255 prevents the liquid that has entered the sill groove 206a from flowing toward the receiving portion 210 side.

[0045] The second sill groove forming portion 230 is formed by bending a sheet metal having the same thickness as the facing material 250. The second sill groove forming portion 230 has a side surface portion 231, an upper surface portion 232 that intersects the side surface portion 231 substantially perpendicularly, and a groove wall surface portion 233 that intersects the upper surface portion 232 substantially perpendicularly.

[0046] The side surface portion 231 faces the wall panel portion 213. The side surface portion 231 is fixed to the wall panel portion 213 using screws. The upper surface portion 232 corresponds to the second upper surface portion according to the present invention. The upper surface portion 232 is supported by the upper surface of the second support portion 214. The groove wall surface portion 233 corresponds to the second groove wall surface portion according to the present invention. The groove wall surface portion 233 faces the groove wall surface portion 253 of the facing material 250 at a predetermined distance in the direction in which the building-side door 205 and the car-side door 125 face each other.

[0047] The distance between the groove wall surface portion 233 and the groove wall surface portion 253 is the width of the sill groove 206a. A plurality of types of second sill groove forming portions 230 according to the present invention are provided. The lengths in the direction in which the building side door 205 and the car side door 125 face each other on the upper surface portion 232 of the plurality of types of second sill groove forming portions 230 are different. Thereby, by replacing the second sill groove forming portion 230, the width of the sill groove 206a can be easily changed. As a result, the workability when changing the width of the sill groove 206a can be improved.

[0048] When the second sill groove forming portion 230 having the shortest length in the direction in which the building side door 205 and the car side door 125 face each other on the upper surface portion 232 is attached to the wall plate portion 213 of the receiving portion 210, the length of the width of the sill groove 206a becomes the longest. In this case, the groove wall surface portion 233 contacts the end surface and the rising portion 255 of the second support portion 214.

[0049] Further, the end surface of the groove wall surface portion 233 abuts on the bottom surface portion 254 of the surface material 250. Thereby, even if the second sill groove forming portion 230 is pushed from above, it can be prevented from rattling. As a result, it is possible to prevent the groove wall surface portion 233 and the second supported portion 245 from colliding and generating noise.

[0050] Note that the configuration of the building side door sill 206 attached to the building structure has been described so far. However, the car side door sill 126 provided in the car 120 can have the same configuration as the building side door sill 206.

[0051] 2. Summary As described above, the building side door sill 206 according to the above-described embodiment includes a receiving portion 210, a first sill groove forming portion 220, and a second sill groove forming portion 230. The receiving portion 210 is fixed to the entrance 201a of the elevator 1 provided in the building structure. The first sill groove forming portion 220 is fixed to the receiving portion 210 and forms the first wall portion of the sill groove 206a. The second sill groove forming portion 230 is detachably fixed to the receiving portion 210 and forms the second wall portion facing the first wall portion of the sill groove 206a. Thus, by replacing the second sill groove forming portion 230, the distance between the first wall portion and the second wall portion of the sill groove 206a (the length of the width of the sill groove 206a) can be easily changed. As a result, the workability when changing the width of the sill groove 206a can be improved.

[0052] Further, the first sill groove forming portion 220 according to the above-described embodiment includes a second supported portion 245 (bottom surface portion) that forms the bottom of the sill groove 206a, a groove wall portion 244 (first groove wall surface portion) that forms the first wall portion of the sill groove 206a continuously with the second supported portion 245, and a horizontal plate portion 243 (first upper surface portion) that is substantially orthogonal to the groove wall portion 244. The second sill groove forming portion 230 includes a groove wall surface portion 233 (second groove wall surface portion) that forms the second wall portion of the sill groove 206a and an upper surface portion 232 (second upper surface portion) that is substantially orthogonal to the groove wall surface portion 233. Thereby, the first sill groove forming portion 220 and the second sill groove forming portion 230 can form the upper surface of the building-side door sill 206 and the sill groove 206a. As a result, it is possible to realize the building-side door sill 206 in which the width of the sill groove 206a can be easily changed while suppressing an increase in the number of parts.

[0053] Further, the groove wall surface portion 233 (second groove wall surface portion) according to the above-described embodiment has an end surface on the side opposite to the upper surface portion 232 (second upper surface portion). The end surface of the groove wall surface portion 233 abuts on the second supported portion 245 (bottom surface portion) of the first sill groove forming portion 220. Thereby, even when the second sill groove forming portion 230 is pushed from above, it is possible to prevent rattling. As a result, it is possible to prevent the groove wall surface portion 233 and the second supported portion 245 from colliding and generating noise.

[0054] Further, the first sill groove forming portion 220 according to the above-described embodiment has a surface material 250 that covers the second supported portion 245 (bottom surface portion), the groove wall portion 244 (first groove wall surface portion), and the horizontal plate portion 243 (first upper surface portion) to form a finished surface. Thereby, the second supported portion 245, the groove wall portion 244, and the horizontal plate portion 243 can be formed of a material that ensures rigidity, and the surface material 250 can be formed of a material that is difficult to ensure rigidity but has a good appearance.

[0055] Further, the surface material 250 and the second sill groove forming portion 230 according to the above-described embodiment are formed by bending a sheet metal having the same plate thickness. Thereby, the appearance surface of the building-side door sill 206 can be formed of the same material. As a result, the building-side door sill 206 can be made to have an overall sense of unity and can be made to look better.

[0056] Further, the receiving portion 210 according to the above-described embodiment has a first support portion 211 that supports the second supported portion 245 (bottom surface portion) of the first sill groove forming portion 220, and a second support portion 214 that supports the upper surface portion 232 (second upper surface portion) of the second sill groove forming portion 230. In this way, since the second support portion 214 supports the upper surface portion 232 of the second sill groove forming portion 230, it is not necessary to form the second sill groove forming portion 230 with a material that can ensure rigidity. As a result, the second sill groove forming portion 230 can be formed of a material that is difficult to ensure rigidity but has a good appearance. In addition, the second sill groove forming portion 230 can be made into a simple shape. Therefore, the second sill groove forming portion 230 can be made into a shape that is easy to attach to and detach from the receiving portion 210.

[0057] Further, the first sill groove forming portion 220 according to the above-described embodiment is fixed to the receiving portion 210 using screws. Thereby, the manufacturing cost of the building-side door sill 206 can be reduced as compared with the case where the first sill groove forming portion 220 is fixed to the receiving portion 210 by welding.

[0058] In addition, the elevator 1 according to the above-described embodiment includes a car 120 and a building-side door sill 206 (door sill). The car 120 moves up and down within a hoistway 110 provided in a building structure and stops at a position facing an entrance 201a provided on each floor of the building structure. The building-side door sill 206 is attached to the entrance 201a (or the car 120 may also be used). The building-side door sill 206 includes a receiving portion 210, a first sill groove forming portion 220, and a second sill groove forming portion 230. The receiving portion 210 is fixed to the entrance 201a of the elevator 1 provided in the building structure. The first sill groove forming portion 220 is fixed to the receiving portion 210 and forms a first wall portion of the sill groove 206a. The second sill groove forming portion 230 is detachably fixed to the receiving portion 210 and forms a second wall portion facing the first wall portion of the sill groove 206a. Accordingly, by replacing the second sill groove forming portion 230, the distance between the first wall portion and the second wall portion of the sill groove 206a (the length of the width of the sill groove 206a) can be easily changed. As a result, the workability when changing the width of the sill groove 206a can be improved.

[0059] As described above, the embodiments of the door sill and the elevator of the present invention have been described including their operational effects. However, the door sill and the elevator of the present invention are not limited to the above-described embodiments, and various modifications can be made without departing from the gist of the invention described in the claims. Further, the above-described embodiments have been described in detail for the purpose of easily explaining the present invention, and are not necessarily limited to those having all the configurations described.

[0060] For example, in the above-described embodiment, the first sill groove forming portion 220 has a configuration having a surface material 250. However, the first sill groove forming portion according to the present invention may be composed only of the base 240. In this case, the upper surface of the horizontal plate portion 243 of the base 240 may be set to the same height as the upper surface of the upper surface portion 232 of the second sill groove forming portion 230.

[0061] In addition, in the above-described embodiment, an example in which double-opening doors are applied as the car-side door 125 and the building-side door 205 has been described. However, as the car-side door and the building-side door according to the present invention, single-opening doors may be applied.

[0062] In addition, the elevator according to the above-described embodiment provides a machine room 160 in the hoistway. However, the elevator according to the present invention may be a so-called machine-roomless elevator that does not provide a machine room in the hoistway.
