Description

[Technical Field]

[0001] The present application relates to an elevator car handrail device and an elevator. [Background technology]

[0002] Elevators are sometimes equipped with handrail devices on their cars to accommodate disabled or elderly people. In conventional handrail devices, the handrail is fixed to the side wall of the car (also called the car panel) by a bracket. The bracket has a flange-shaped part that is fixed to the side wall, and the flange part is fixed to the side wall with a screw. In addition, the holes in the handrail support part on the side wall of the car are sometimes made elongated to adjust for manufacturing errors in the parts.

[0003] However, if the screws and slots for fixing the handrail are visible, it is not desirable from an appearance perspective. Therefore, in order to hide the screw heads, for example, the entire flange portion is covered with a cover (for example, Patent Document 1). [Prior art documents] [Patent documents]

[0009] In each drawing, the dimensions of the components may be enlarged or reduced relative to the actual dimensions, for example, to facilitate understanding, and the dimensional ratios between the drawings may not be consistent. Note that in each drawing, for example, to facilitate understanding, some of the components may be omitted.

[0010] Terms including ordinal numbers such as "first" and "second" are used to describe various components, but these terms are used only to distinguish one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. Furthermore, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0011] An embodiment of an elevator car handrail device and an elevator will be described below with reference to Figures 1 to 9. Note that in each figure, the dimensional ratios in the drawing do not necessarily match the actual dimensional ratios, and the dimensional ratios between the drawings do not necessarily match either.

[0012] As shown in FIG. 1, the elevator 1 may include, for example, a car 2 for passengers to ride in, car ropes 3 connected to the car 2, an elevator counterweight (hereinafter also simply referred to as "counterweight") 4 connected to the car ropes 3, a hoist 5 that drives the car ropes 3 to move the car 2 and counterweight 4 in the vertical direction D3, a car rail 6 that guides the car 2, a counterweight rail 7 that guides the counterweight 4, and a processing unit 8 that controls each part of the elevator 1.

[0013] Although the elevator 1 according to this embodiment is configured such that the hoisting machine 5 is disposed inside the machine room X2, the configuration is not limited to this. For example, the elevator 1 may be configured such that the machine room X2 is not provided and the hoisting machine 5 is disposed inside the hoistway X1.

[0014] In each drawing, the first direction D1 is the first horizontal direction D1, the second direction D2 is the second horizontal direction D2 that is a horizontal direction perpendicular to the first horizontal direction D1, and the third direction D3 is the up-down direction D3 that is perpendicular to each of the horizontal directions D1 and D2, and is the lifting direction in which the car 2 and the counterweight 4 move up and down. Although not particularly limited, the entrance / exit direction in which passengers move to enter and exit the car 2 may be, for example, the second horizontal direction D2 as in this embodiment.

[0015] As shown in Fig. 2, the elevator 1 may include an elevator car handrail device 20 attached to a side wall surface 2a of the car 2. The side wall surface 2a of the car 2 may be composed of a plurality of panels arranged in the first horizontal direction D1 or the second horizontal direction D2. In this embodiment, the elevator car handrail device 20 is fixed to the side wall surface 2a extending along the first horizontal direction D1 and the vertical direction D3, but is not limited to this. The elevator car handrail device 20 may also be fixed to a side wall surface 2a extending along the second horizontal direction D2 and the vertical direction D3.

[0016] The elevator car handrail device 20 may include a handrail 9. The handrail 9 in this embodiment extends in a first horizontal direction D1. The handrail 9 may have a cylindrical shape extending in the first horizontal direction D1. Furthermore, both ends of the handrail 9 in the first horizontal direction D1 may be closed by end covers 9a.

[0017] The elevator car handrail device 20 may also include fixing members 10 that fix the handrail 9 to the side wall surface 2a. The fixing members 10 are provided on both ends of the handrail 9 in the first lateral direction D1.

[0018] 3 to 5, the fixing member 10 may include a first member 11 attached to the handrail 9 and a second member 12 attached to the side wall surface 2a of the car 2. The fixing member 10 may also include a connecting screw 13, a first fixing bolt 14, a second fixing bolt 15, and a cover 16.

[0019] The first member 11 is fixed to the handrail 9. The first member 11 is pin-shaped. The first member 11 may include a base portion 11a fixed to the handrail 9 and an insertion portion 11b extending from the base portion 11a.

[0020] The base portion 11a is generally disk-shaped as shown in Figures 3 to 7. The surface of the base portion 11a facing the handrail 9 may be shaped to follow the shape of the outer surface of the handrail 9, and for example, as shown in Figure 6, it may be a concave surface 11c with an arc-shaped cross section in comparison with the handrail 9 which has a circular cross section.

[0021] 7, the outer surface of the insertion portion 11b has a substantially square cross section and includes an upper outer surface 11d and a lower outer surface 11e that are parallel to each other. The upper outer surface 11d and the lower outer surface 11e are arranged to extend along the first lateral direction D1 and the second lateral direction D2.

[0022] The insertion portion 11b may have a female thread portion 11f formed on the lower outer surface 11e. A connecting screw 13 is screwed into the female thread portion 11f from below.

[0023] As shown in Figures 6 and 7, the first member 11 may have a recess 11g that opens toward the side wall surface 2a, and a through-hole 11h that is formed at the bottom of the recess 11g so as to penetrate in the second horizontal direction D2. The recess 11g has a circular cross section. The first member 11 is fixed to the handrail 9 by a first fixing bolt 14 that passes through the through-hole 11h. The handrail 9 is not particularly limited, but may have a female threaded member 9b that the first fixing bolt 14 screws into, as shown in Figure 4. The first member 11 may be fixed to the handrail 9 at the work site, or the handrail 9 to which the first member 11 is fixed may be transported to the work site in advance.

[0024] The second member 12 is fixed to a side wall surface 2a of the car 2. As shown in Fig. 8 and Fig. 9, the second member 12 may include a cylindrical portion 12a and a bottom portion 12b that closes one end of the cylindrical portion 12a.

[0025] As shown in Fig. 9, the outer surface of the cylindrical portion 12a has a circular cross section. The inner surface of the cylindrical portion 12a has a generally rectangular cross section and includes an upper inner surface 12c and a lower inner surface 12d that are parallel to each other. The upper inner surface 12c and the lower inner surface 12d are arranged to extend along the first lateral direction D1 and the second lateral direction D2.

[0026] The insertion portion 11b of the first member 11 is inserted into the cylindrical portion 12a of the second member 12. A height h2 (see FIG. 8) between the upper inner surface 12c and the lower inner surface 12d of the second member 12 is slightly larger than a height h1 (see FIG. 6) between the upper outer surface 11d and the lower outer surface 11e of the first member 11, and the cylindrical portion 12a restricts movement of the insertion portion 11b in the up-down direction D3. On the other hand, a width w2 (see FIG. 9) between the upper inner surface 12c and the lower inner surface 12d of the second member 12 in the first lateral direction D1 is larger than a width w1 (see FIG. 7) between the upper outer surface 11d and the lower outer surface 11e of the first member 11, and the cylindrical portion 12a allows movement of the insertion portion 11b in the first lateral direction D1. This allows the first member 11 to slide in the first horizontal direction D1 relative to the second member 12 fixed to the side wall surface 2a. As a result, even if, for example, a manufacturing error occurs in the side wall surface 2a of the car 2 or an installation error occurs when fixing the second member 12 to the side wall surface 2a, the error can be adjusted by sliding the first member 11 in the first horizontal direction D1.

[0027] As shown in FIGS. 8 and 9 , the cylindrical portion 12a may have a first elongated hole 12e formed to extend in the first horizontal direction D1. The first elongated hole 12e penetrates in the up-down direction D3 from the lower surface of the cylindrical portion 12a to the lower inner surface 12d. A connecting screw 13 is inserted into the first elongated hole 12e from below. With the insertion portion 11b of the first member 11 inserted into the cylindrical portion 12a, the connecting screw 13 threads into the female thread portion 11f of the first member 11. This secures the cylindrical portion 12a to the insertion portion 11b by the connecting screw 13. As described above, the first elongated hole 12e is formed on the lower side of the second member 12, and the connecting screw 13 is inserted into the first elongated hole 12e from below the second member 12. Therefore, the connecting screw 13 and the first elongated hole 12e for securing the handrail 9 to the side wall surface 2a of the car 2 are difficult to see. Furthermore, as shown in Figure 4, the connecting screw 13 sandwiches the tubular portion 12a between the lower outer surface 11e of the insertion portion 11b with the head thereof abutting the underside of the tubular portion 12a, thereby reducing the amount by which the connecting screw 13 protrudes from the underside of the tubular portion 12a, making the connecting screw 13 even less visible.

[0028] The bottom surface portion 12b is fixed to the side wall surface 2a. As shown in FIGS. 8 and 9, the bottom surface portion 12b may have a second elongated hole 12f formed to extend in the first lateral direction D1. A second fixing bolt 15 is inserted into the second elongated hole 12f through the inside of the cylindrical portion 12a. The second fixing bolt 15 is threaded into a fixing hole 2b (see FIGS. 3 and 4) formed in the side wall surface 2a. As a result, the bottom surface portion 12b is fixed to the side wall surface 2a by the second fixing bolt 15. The second fixing bolt 15 has a larger diameter than the first fixing bolt 14.

[0029] 8 and 9, the bottom surface portion 12b may have a protrusion 12g extending toward the side wall surface 2a. The protrusion 12g is disposed below the second elongated hole 12f, although it is not particularly limited thereto. The protrusion 12g has a cylindrical shape, although it is not particularly limited thereto.

[0030] The side wall surface 2a may have a third elongated hole 2c (see FIGS. 3 and 4) formed along the first horizontal direction D1. The third elongated hole 2c is disposed below the fixing hole 2b, although this is not a particular limitation. The third elongated hole 2c is disposed so as to face the protrusion 12g of the second member 12 when the second elongated hole 12f of the second member 12 faces the fixing hole 2b. The protrusion 12g of the second member 12 is inserted into the third elongated hole 2c. This prevents the second member 12 from being oriented upside down when the second member 12 is fixed to the side wall surface 2a. The third elongated hole 2c restricts movement of the protrusion 12g in the up-down direction D3 while allowing movement in the first horizontal direction D1. This allows the second member 12 to slide in the first horizontal direction D1 relative to the side wall surface 2a. As a result, even if a manufacturing error occurs in the panel that constitutes the side wall surface 2a, the error can be adjusted by sliding the second member 12 in the first horizontal direction D1.

[0031] The cover 16 covers the peripheries of the first member 11 and the second member 12. The cover 16 is cylindrical. The surface of the cover 16 facing the handrail 9 may have a shape that follows the shape of the outer surface of the handrail 9, similar to the first member 11, as shown in FIGS. 3 to 5. The cover 16 may have a fourth elongated hole 16a formed to extend in the first lateral direction D1, as shown in FIGS. 3 to 5. The fourth elongated hole 16a is formed in a position that overlaps with the first elongated hole 12e when viewed from below when the cover 16 covers the second member 12. In other words, the connecting screw 13 is inserted through the fourth elongated hole 16a and the first elongated hole 12e and threaded into the female thread portion 11f of the first member 11.

[0032] 4, the head of the connecting screw 13 is received in the fourth elongated hole 16a. The connecting screw 13 is, for example, a flat head screw, and the fourth elongated hole 16a is countersunk to match the shape of the head of the connecting screw 13.

[0033] [1] As described above, the elevator car handrail device 20, as in this embodiment, comprises: a handrail 9 extending in a first horizontal direction D1 parallel to the side wall surface 2a of the car 2; a first member 11 attached to the handrail 9 and facing the side wall surface 2a; and a second member 12 attached to the side wall surface 2a and facing the first member 11 in a second horizontal direction D2 perpendicular to the up-down direction D3 and the first horizontal direction D1; one of the first member 11 and the second member 12 (the second member in this embodiment) 12 comprises a cylindrical portion 12a that opens toward the other (the first member in this embodiment) 11; The other (in this embodiment, the first member) 11 of the second member 12 has an insertion portion 11b that is inserted into the cylindrical portion 12a, and the cylindrical portion 12a restricts movement of the insertion portion 11b in the vertical direction D3 while allowing movement in the first horizontal direction D1, and the cylindrical portion 12a has a first hole (in this embodiment, a first long hole) 12e that penetrates from the underside to the inside in the vertical direction D3, and when the insertion portion 11b is inserted, it is fixed to the insertion portion 11b from below by a connecting screw 13 that passes through the first hole (in this embodiment, the first long hole) 12e.

[0034] With this configuration, even if there is a manufacturing error in the side wall surface 2a of the car 2 or an installation error when fixing the second member 12 to the side wall surface 2a, the error can be adjusted by sliding the first member 11 in the first lateral direction D1. Furthermore, with this configuration, the first member 11 and the second member 12 are fixed from below by connecting screws 13, so the screws and elongated holes used to fix the handrail 9 to the side wall surface 2a of the car 2 are not easily visible.

[0035] [2] Furthermore, in the elevator car handrail device 20 of [1] above, it is preferable that the first hole (in this embodiment, the first elongated hole) 12e extends in the first horizontal direction D1, the insertion portion 11b has a female thread portion 11f formed on the lower outer surface 11e, and the connecting screw 13 is inserted through the first hole (in this embodiment, the first elongated hole) 12e and screwed into the female thread portion 11f.

[0036] With this configuration, the connecting screw 13 clamps the tubular portion 12a between itself and the lower outer surface 11e of the insertion portion 11b with its head abutting the underside of the tubular portion 12a, thereby reducing the amount by which the connecting screw 13 protrudes from the underside of the tubular portion 12a, making the connecting screw 13 even less visible.

[0037] [3] Furthermore, in the elevator car handrail device 20 of [1] or [2] above, it is preferable that the second member 12 comprises the cylindrical portion 12a and a bottom portion 12b that closes one end of the cylindrical portion 12a, the bottom portion 12b comprises a second hole (in this embodiment, a second elongated hole) 12f extending in the first horizontal direction D1, and the second member 12 is fixed to the side wall surface 2a by a fixing bolt (in this embodiment, a second fixing bolt) 15 that is inserted through the second hole (in this embodiment, the second elongated hole) 12f.

[0038] According to this configuration, even if a manufacturing error in the side wall surface 2a of the car 2 is so large that the error cannot be adjusted between the first member 11 and the second member 12, the error can be adjusted by sliding the second member 12 in the first lateral direction D1. In other words, even if there is a large manufacturing error in the side wall surface 2a of the car 2 or a large attachment error when fixing the second member 12 to the side wall surface 2a, the error can be adjusted.

[0039] [4] In any of the elevator car handrail devices 20 [1] to [3] above, it is preferable that the elevator car handrail device 20 further includes a cover 16 that covers the periphery of the first member 11 and the second member 12, and that the cover 16 has a fourth hole (in this embodiment, a fourth elongated hole) 16a that overlaps with the first hole (in this embodiment, a first elongated hole) 12e when viewed from below, and that the head of the connecting screw 13 is accommodated in the fourth hole (in this embodiment, a fourth elongated hole) 16a.

[0040] With this configuration, the head of the connecting screw 13 is housed in the fourth elongated hole 16a, making it even less visible.

[0041] [5] Furthermore, as in this embodiment, the elevator 1 preferably comprises a car 2 and the elevator car handrail device 20 described above in [3] attached to the side wall surface 2a of the car 2, the bottom surface portion 12b having a protrusion 12g extending toward the side wall surface 2a, the side wall surface 2a having a third hole (in this embodiment, a third long hole) 2c into which the protrusion 12g is inserted, and the third hole (in this embodiment, the third long hole) 2c restricts movement of the protrusion 12g in the vertical direction D3 while allowing movement in the first horizontal direction D1.

[0042] According to this configuration, even if a manufacturing error occurs in the side wall surface 2a of the car 2, the error can be adjusted by sliding the second member 12 in the first lateral direction D1.

[0043] [6] Furthermore, it is preferable that the elevator 1 includes the car 2 and the elevator car handrail device 20 described in [1] or [2] above, which is attached to the side wall surface 2a of the car 2, as in this embodiment.

[0044] With this configuration, for example, even if there is a manufacturing error in the side wall surface 2a of the car 2 or an installation error when fixing the second member 12 to the side wall surface 2a, the first member 11 can be adjusted by sliding it in the first lateral direction D1. Furthermore, with this configuration, the first member 11 and the second member 12 are fixed from below with connecting screws 13, so the screws and elongated holes used to fix the handrail 9 to the side wall surface 2a of the car 2 are difficult to see.

[0045] The elevator car handrail device 20 and the elevator 1 are not limited to the configuration of the above-described embodiment, nor are they limited to the above-described effects. Furthermore, it goes without saying that various modifications can be made to the elevator car handrail device 20 and the elevator 1 without departing from the spirit of the present invention. For example, it goes without saying that one or more of the configurations, methods, etc. according to the various modified examples described below may be arbitrarily selected and adopted in the configurations, methods, etc. according to the above-described embodiment.

[0046] (A) In the elevator car handrail device 20 according to the above embodiment, the second member 12 has a cylindrical portion 12a that opens toward the first member 11, and the first member 11 has an insertion portion 11b that is inserted into the cylindrical portion 12a. However, the elevator car handrail device 20 is not limited to this configuration. For example, the first member 11 may have a cylindrical portion that opens toward the second member 12, and the second member 12 may have an insertion portion that is inserted into the cylindrical portion.

[0047] (B) In the elevator car handrail device 20 according to the above embodiment, the handrail 9 extends parallel to the side wall surface 2a of the car 2. However, the elevator car handrail device 20 is not limited to this configuration. For example, the handrail 9 may extend at an angle relative to the side wall surface 2a of the car 2.

[0048] (C) In addition, in the elevator car handrail device 20 according to the above embodiment, the handrail 9 is configured to extend horizontally. However, the elevator car handrail device 20 is not limited to this configuration. For example, the handrail 9 may be configured to extend in a direction that is inclined up or down relative to the horizontal. Furthermore, the handrail 9 does not need to extend linearly, and may have a curved portion that extends in the vertical direction D3.

[0049] (D) In the elevator car handrail device 20 according to the above embodiment, the inner surface of the cylindrical portion 12a has a generally rectangular cross section, and the outer surface of the insertion portion 11b has a generally square cross section. However, the elevator car handrail device 20 is not limited to this configuration. For example, the outer surface of the insertion portion 11b may also have a generally rectangular cross section.

[0050] (E) In the elevator car handrail device 20 according to the above embodiment, the first elongated hole 12e extends in the first horizontal direction D1, the insertion portion 11b has an internally threaded portion 11f formed on the lower outer surface 11e, and the connecting screw 13 is inserted through the first elongated hole 12e and threadedly engages with the internally threaded portion 11f. However, the elevator 1 is not limited to this configuration. For example, the tubular portion 12a may have an internally threaded portion that penetrates from the lower surface to the interior in the vertical direction D3, and the connecting screw 13 may be threadedly engaged with the internally threaded portion and its tip may abut the lower outer surface 11e of the insertion portion 11b.

[0051] (F) In the elevator car handrail device 20 according to the above embodiment, the second member 12 includes a cylindrical portion 12a and a bottom surface portion 12b closing one end of the cylindrical portion 12a, the bottom surface portion 12b includes a second elongated hole 12f extending in the first horizontal direction D1, and the second member 12 is fixed to the side wall surface 2a by a second fixing bolt 15 inserted through the second elongated hole 12f. However, the elevator car handrail device 20 is not limited to this configuration. For example, the second member 12 may also include a cylindrical portion 12a and a bottom surface portion 12b closing one end of the cylindrical portion 12a, the bottom surface portion 12b includes a circular hole penetrating in the second horizontal direction D2, and the second member 12 is fixed to the side wall surface 2a by a second fixing bolt 15 inserted through the circular hole. That is, the second member 12 does not necessarily have to be able to adjust its position by sliding in the first lateral direction D1 relative to the side wall surface 2a.

[0052] (G) The elevator car handrail device 20 according to the above embodiment further includes a cover 16 that covers the periphery of the first member 11 and the second member 12. The cover 16 has a fourth elongated hole 16a that overlaps with the first elongated hole 12e when viewed from below, and the head of the connecting screw 13 is received in the fourth elongated hole 16a. However, the elevator car handrail device 20 is not limited to this configuration. For example, the elevator 1 does not necessarily have to include the cover 16. However, for reasons of appearance or safety, it is preferable that the elevator 1 include the cover 16. Furthermore, the head of the connecting screw 13 may abut against the underside of the cover 16, sandwiching the tubular portion 12a and the cover 16 between the cover 16 and the lower outer surface 11e of the insertion portion 11b.

[0053] (H) The elevator 1 according to the above embodiment includes a car 2 and an elevator car handrail device 20 attached to a side wall surface 2a of the car 2. The bottom surface 12b includes a protrusion 12g extending toward the side wall surface 2a, and the side wall surface 2a includes a third elongated hole 2c into which the protrusion 12g is inserted. The third elongated hole 2c restricts movement of the protrusion 12g in the up-down direction D3 while allowing movement in the first lateral direction D1. However, the elevator 1 is not limited to this configuration. For example, the side wall surface 2a may include a protrusion extending toward the bottom surface 12b, and the bottom surface 12b may include a elongated hole into which the protrusion is inserted. The elongated hole restricts movement of the protrusion in the up-down direction D3 while allowing movement in the first lateral direction D1.

[0054] (I) In addition, in the elevator 1 according to the above embodiment, the protrusion 12g is arranged below the second elongated hole 12f, and the third elongated hole 2c is arranged below the fixing hole 2b. However, the elevator 1 is not limited to this configuration. For example, the protrusion 12g may be arranged above the second elongated hole 12f, and the third elongated hole 2c may be arranged above the fixing hole 2b.

[0055] (J) In the elevator car handrail device 20 according to the above embodiment, the protrusion 12g is configured to have a cylindrical shape. However, the elevator car handrail device 20 is not limited to this configuration. For example, the protrusion 12g may be configured to have a square prism shape.

[0056] (K) In the elevator car handrail device 20 according to the above embodiment, the through hole 11h is a circular hole.
