Summary of the Invention

Problems to be Solved by the Invention

[0004] In the above-described configuration, the fixing device is attached to the top of the car, but other on-car devices such as an instrument box and a cooler are also installed on the top of the car. Therefore, the mass of the car increases, and as a result, the mass of the counterweight also increases, which is a factor causing an increase in cost.

[0005] Therefore, an object of the present invention is to provide an elevator and a fixing device for a car that can reduce the weight of the car.

Means for Solving the Problems

[0006] In order to solve the above problems, for example, the configuration described in the claims is adopted. The present invention includes several means for solving the above problems, but one example is an elevator comprising a car and a fixing device for stopping the movement of the car, wherein the fixing device comprises a movable unit provided at a predetermined height on the track on which the car travels and having a fitting member that can protrude from the inner wall of the track to the car, and a restricting member provided on the car that fits with the fitting member to restrict the movement of the car. [Effects of the Invention]

[0007] The present invention provides an elevator and a device for securing the elevator car that can reduce the weight of the elevator car. [Brief explanation of the drawing]

[0009] Hereinafter, embodiments to which the present invention is applied will be described with reference to the drawings. In each embodiment, the same components are denoted by the same reference numerals, and redundant descriptions are omitted.

[0010] ≪First Embodiment≫ <Elevator> Figure 1 is a configuration diagram of the elevator 1 and the elevator car fixing device 2 according to the first embodiment, and corresponds to a top view of the elevator 1 as seen from above. As shown in this figure, the elevator 1 has an elevator car 11, guide rails 12, counterweights 13, main rope 14, hoisting machine 15, and control panel 16 within a travel track 10 provided along the building. Furthermore, the elevator 1 is equipped with a fixing device 2 for restricting the movement of the elevator car 11 during inspection of the elevator 1. These are configured as follows.

[0011] [Riding basket 11] The elevator car 11 is box-shaped, and a car door 11a for boarding and alighting is provided on a part of the side wall. Two channel-shaped guide members 11b are fixed to the two outer walls of the elevator car 11 that are perpendicular to the car door 11a, projecting horizontally outward from the elevator car 11. These two guide members 11b are positioned along the direction of travel of the elevator car 11 with their channel-shaped openings facing outward. The two guide members 11b may also be fixed to a frame that surrounds the outer circumference of the elevator car 11.

[0012] Furthermore, a crosshead 11c, which serves as a frame, is positioned above the elevator car 11 and fixed to the elevator car 11. In addition, part of the fixing device 2, which will be described later, is positioned above the elevator car 11, and air conditioning equipment 3 and equipment boxes 4 may also be positioned there. The equipment boxes 4 house, for example, the control panel and electrical wiring boards.

[0013] [Guide rail 12] The guide rails 12 are erected on both sides of the car 11 at positions sandwiching the car 11. Each of these guide rails 12 is fixed to the traveling path 10 via a rail bracket 10b fixed to the inner wall of the traveling path 10. Such guide rails 12 are, for example, T-shaped steels, and each guide member 11b made of a channel steel fixed to the car 11 slidably engages therewith to guide the traveling of the car 11.

[0014] [Counterweight 13, main rope 14, hoist 15] The counterweight 13 is for balancing with the car 11. The main rope 14 is passed around a pulley (not shown) fixed to the car 11 and is suspended in a bottle shape to balance the car 11 and the counterweight 13. Further, the hoist 15 is driven with an intermediate portion of the main rope 14 wound thereon to run the car 11 suspended by the main rope 14. Note that the traveling of the counterweight 13 within the traveling path 10 is also guided by another guide rail 12a fixed to the inner wall of the traveling path 10.

[0015] [Control panel 16] The control panel 16 controls the traveling of the car 11 and the opening and closing of the car door 11a. The control of the driving of the car 11 and the car door 11a by the control panel 16 is performed based on signals from landing call buttons and car call buttons (not shown here), as well as an operation unit and a fixing device 2 to be described later.

[0016] Such a control panel 16 is constituted by a computer. The computer is hardware used as a so-called computer, and includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a non-volatile storage unit such as a ROM (Read Only Memory) or an HDD (hard disk drive), and further a network interface. The control panel 16 constituted by the computer performs drive control of the elevator according to a program stored in the storage unit of the computer. Note that the location where the control panel 16 is arranged is not particularly limited, and it may be within the traveling path 10, within the car 11, above the car 11, or within the machine room if there is a machine room above the traveling path 10.

[0017] <Fixing device 2> FIG. 2 is a perspective view of the fixing device 2 of the car according to the first embodiment. FIG. 3 is a diagram (part 1) for explaining the configuration of the fixing device of the car according to the first embodiment, FIG. 3A is a top view, FIG. 3B is a front view, and shows the state of the elevator during normal operation. Further, FIG. 4 is a diagram (part 2) for explaining the configuration of the fixing device of the car according to the first embodiment, FIG. 4A is a top view, FIG. 3B is a front view, and shows the state when the movement of the car is restricted. These FIGS. 2 to 4 are diagrams of the fixing device 2 on the right side in the drawing among the two fixing devices 2 shown in FIG. 1. Hereinafter, the configuration of the fixing device 2 will be described based on these figures and FIG. 1 described above.

[0018] The fixing device 2 is a mechanism part for restricting the movement of the car 11, and two fixing devices 2 are provided at positions sandwiching the car 11. Each of these fixing devices 2 includes a movable unit 100 fixed to the traveling path 10 and a restricting unit 200 fixed to the car 11. They are as follows.

[0019] [Movable unit 100] The movable unit 100 is fixed to a predetermined height on the travel track 10 via a rail bracket 10b (not shown in Figure 2) fixed to the inner wall of the travel track 10. The height at which the movable unit 100 is fixed is the height at which the elevator car 11 is stopped when inspecting the elevator 1, and is the height corresponding to the regulating unit 200 provided on the elevator car 11. The two movable units 100, which are arranged on either side of the elevator car 11, may be symmetrical in their configuration, or they may be of the same shape. Furthermore, by fixing the movable unit 100 to the rail bracket 10b for fixing the guide rail 12, it is not necessary to prepare a separate member for fixing the movable unit 100, but the configuration is not limited to this.

[0020] Such a movable unit 100 includes a stopper pin 101, a support housing 102, a handle 103, a short connector 104, and further, a first connector 105a and a second connector 105b. The movable unit 100 is fixed to the rail bracket 10b in the support housing 102 using fixing members such as screws. The individual parts constituting the movable unit 100 will be described below.

[0021] -Stopper pin 101- The stopper pin 101 is rod-shaped, for example, cylindrical, and is supported by the support housing 102 (described below) so as to be able to protrude horizontally from the wall of the travel path 10 (see Figure 1). This stopper pin 101 has sufficient length to reach from the wall side of the travel path 10, which is closer to the guide rail 12, to the regulating unit 200 (described below). Such a stopper pin 101 is a fitting member that engages with the regulating member 201 of the regulating unit 200 (described below) to restrict the movement of the elevator car 11, and the movement during the engagement operation with the regulating member 201 is kept to a minimum.

[0022] -Support housing 102- The support housing 102 is fixed to the wall of the track 10 via a rail bracket 10b, and supports the stopper pin 101 so that it can protrude from the wall of the track 10 toward the elevator car 11. Such a support housing 102 comprises two parallel track walls 102a and 102b. These track walls 102a and 102b have through holes 102aa and 102bb through which the stopper pin 101 is slidably inserted, thereby restricting the direction of movement of the stopper pin 101. In addition, the track walls 102a and 102b support the stopper pin 101 by inserting it through the through holes 102aa and 102bb.

[0023] Furthermore, the support housing 102 has a restricting wall 102c perpendicular to the two track walls 102a and 102b. This restricting wall 102c is positioned closer to the wall of the track 10 than the two track walls 102a and 102b, and is positioned parallel to the stopper pin 101 supported by the two track walls 102a and 102b.

[0024] Such a restricting wall 102c has a first fitting portion 102d and a second fitting portion 102e. These first fitting portion 102d and second fitting portion 102e are notches provided in the restricting wall 102c, and the restricting wall 102c is notched in a direction perpendicular to the extension direction of the stopper pin 101 supported by the two track walls 102a and 102b. In the illustrated example, the first fitting portion 102d and the second fitting portion 102e are notched from top to bottom, but they may also be notched from bottom to top.

[0025] -Handle 103- The handle 103 extends perpendicularly from the side circumferential wall of the stopper pin 101 with respect to the axial direction of the stopper pin 101, and is an operating part for rotating the stopper pin 101 around its axis and moving the stopper pin 101 in the axial direction. The handle 103 has a protruding length and diameter that allows it to be freely fitted into the first fitting portion 102d and the second fitting portion 102e, respectively, by the rotation and movement of the stopper pin 101. The handle 103 also has a shape that facilitates the operation of rotating and moving the stopper pin 101 by an operator.

[0026] When the handle 103 is fitted into the first fitting portion 102d (see Figures 2, 3A, and 3B), the tip of the stopper pin 101 is housed within the support housing 102, on the guide rail 12 side. In this state, the stopper pin 101 is held in a state supported by the two track walls 102a and 102b. When the handle 103 is fitted into the second fitting portion 102e (see Figures 4A and 4B), the tip of the stopper pin 101 protrudes from the support housing 102 and the guide rail 12, reaching the elevator car 11 and the regulating unit 200. In this state, the stopper pin 101 is held in a state supported by the two track walls 102a and 102b.

[0027] -Short connector 104- The short connector 104 is used to connect either of the two connectors described below, the first connector 105a and the second connector 105b, by making them electrically connected, and is inserted into either of them, for example. Such a short connector 104 is attached to the handle 103 and moves together with the handle 103 between the first mating portion 102d and the second mating portion 102e.

[0028] -First connector 105a and second connector 105b- The first connector 105a and the second connector 105b become electrically connected when the short connector 104 is inserted, and a signal indicating the connection state is transmitted to the control panel 16.

[0029] Of these, the first connector 105a allows the short connector 104 fixed to the handle 103 to be freely inserted when the handle 103 is fitted into the first mating portion 102d. When the first connector 105a is connected, the control panel 16, which receives a signal from the first connector 105a, permits normal operation of the elevator 1. The control panel 16 also determines whether to permit or deny each operation by the operating unit installed, for example, inside the equipment box 4 or on top of the elevator car 11, based on the signal received from the first connector 105a.

[0030] Furthermore, when the handle 103 is engaged with the second mating portion 102e, the short connector 104 fixed to the handle 103 can be freely inserted into the second connector 105b. When the second connector 105b is connected, the control panel 16, which receives a signal from the second connector 105b, disables the normal operation of the elevator 1. The control panel 16 also determines whether to permit or deny each operation by the operating unit installed inside the equipment box 4 or on top of the elevator car 11 based on the signal received from the second connector 105b.

[0031] Although not shown in the illustration here, the support housing 102 may be provided with a removable cover member to prevent unintended operation of the handle 103 and the short connector 104.

[0032] [Regulatory Unit 200] The regulating unit 200 is fixed to both sides of the elevator car 11, for example, via a crosshead 11c (shown only in Figure 1). Such a regulating unit 200 comprises a regulating member 201 and a holding member 202. These are as follows:

[0033] -Regulatory member 201- The restricting member 201 is a plate-shaped member having a through hole 201a into which the stopper pin 101 of the movable unit 100 is inserted and fitted. The restricting member 201 restricts the movement of the elevator car 11 when the stopper pin 101 is fitted into the through hole 201a.

[0034] -Retaining member 202- The retaining member 202 is a plate-shaped member fixed at a position where the tip of the stopper pin 101 abuts, and has a recess 202a that accommodates the tip of the stopper pin 101. Such a retaining member 202 also functions as a restricting member that restricts the movement of the elevator car 11 when the stopper pin 101 is inserted into and fitted into the recess 202a. The restricting unit 200 shall have at least one of the restricting member 201 and the retaining member 202 which functions as a restricting member.

[0035] Furthermore, in such a retaining member 202, a switch 202b may be provided on the bottom surface of the recess 202a, which is turned ON when the tip of the stopper pin 101 contacts it. Such a switch 202b is positioned so that the tip of the stopper pin 101 contacts it when the stopper pin 101 is moved to the position where the handle 103 is fitted into the second fitting portion 102e.

[0036] Furthermore, switch 202b is wired into the equipment box 4 on the elevator car 11, and the signal generated when switch 202b is turned ON is transmitted from the equipment box 4 to the control panel 16. Therefore, the wiring route is short and simple. When the control panel 16 receives the signal that switch 202b is turned ON, it disables the normal operation of elevator 1. The control panel 16 determines whether to permit or deny each operation by the operating unit in the equipment box 4 based on the signal received from switch 202b. For this reason, if switch 202b is provided in the regulatory unit 200, the short connect 104, first connector 105a, and second connector 105b provided in the movable unit 100 may be provided as needed.

[0037] <Effects of the First Embodiment> In the first embodiment described above, a movable unit 100 for restricting the movement of the elevator car 11 is fixed to the travel path 10, and only plate-shaped restricting members 201 and holding members 202 are fixed to the elevator car 11. This reduces the mass of the elevator car 11 and the mass of the counterweight 13 compared to the case where the movable unit 100 is fixed on the elevator car 11, thereby reducing the product cost of the elevator 1. Furthermore, since there is free space that would otherwise be occupied by the movable unit 100 when it is fixed on the elevator car 11, it is possible to secure workspace.

[0038] ≪Second Embodiment≫ <Elevator> The elevator of the second embodiment differs from the elevator of the first embodiment, which was described using Figure 1, only in the configuration of the fixing device. Therefore, only the fixing device of the second embodiment will be described below.

[0039] <Fixing device 2'> Figure 5 is a front view (part 1) of the elevator car fixing device 2' according to the second embodiment, showing the elevator in its normal operating state. Figure 6 is a front view (part 2) of the elevator car fixing device 2' according to the second embodiment, showing the elevator car in its restricted movement state. The difference between the elevator car fixing device 2' shown in these figures and the elevator car fixing device described in the first embodiment is that the restricting unit 200' side is equipped with a switch unit 203' instead of a holding member. The configuration of the restricting member 201 in the movable unit 100 and the restricting unit 200' is the same as that of the first embodiment.

[0040] [Regulatory Unit 200'] -Switch section 203'- The switch section 203' is a roller-type switch provided at the position where the tip of the stopper pin 101 contacts it, and comprises a switch housing 203a', a switch 203b', and a roller 203c'. The switch housing 203a' holds the switch 203b' and the roller 203c' and is fixed to the upper part of the passenger basket 11. The switch 203b' is turned ON by the roller 203c'. While fixed to the upper part of the passenger basket 11, the roller 203c' is pushed and moved by the tip of the stopper pin 101 during the process of moving the stopper pin 101 to the position where the handle 103 is fitted into the second fitting portion 102e, thereby turning on the switch 203b' (see Figure 6).

[0041] Furthermore, switch 203b' is wired into the equipment box 4 on the elevator car 11, and the signal generated when switch 203b' is turned ON is transmitted from the equipment box 4 to the control panel 16. Therefore, the wiring route is short and simple. When the control panel 16 receives the signal that switch 203b' is turned ON, it disables the normal operation of elevator 1. The control panel 16 determines whether to allow or disallow each operation by the operating unit in the equipment box 4 based on the signal received from switch 203b'. For this reason, if switch 203b' is provided in the regulatory unit 200', the short connect 104, first connector 105a, and second connector 105b provided in the movable unit 100 only need to be provided as needed.

[0042] <Effects of the second embodiment> Even in the second embodiment described above, the movable unit 100 for restricting the movement of the elevator car 11 is fixed to the travel path 10 side, and only the plate-shaped restricting member 201 and the switch unit 203' are fixed to the elevator car 11. As a result, as in the first embodiment, the mass of the elevator car 11 can be reduced compared to the case where the movable unit 100 is fixed on the elevator car 11, and the mass of the counterweight 13 can also be reduced, thus reducing the product cost of the elevator 1. Furthermore, since the space occupied by the movable unit 100, which is fixed on the elevator car 11, becomes available, it is also possible to secure workspace.

[0043] ≪Third Embodiment≫ <Elevator> The elevator of the third embodiment differs from the elevator of the first embodiment, which was described using Figure 1, only in the configuration of the fixing device. Therefore, only the fixing device of the third embodiment will be described below.

[0044] <Fixing device 2”> Figure 7 is a front view (part 1) of the elevator car fixing device 2" according to the third embodiment, showing the elevator in its normal operating state. Figure 8 is a front view (part 2) of the elevator car fixing device 2" according to the third embodiment, showing the elevator car in a restricted state. The difference between the elevator car fixing device 2" shown in these figures and the elevator car fixing device described in the first embodiment lies in the configuration of the movable unit 100" and the restricting unit 200". The configuration of the movable unit 100" and the restricting unit 200" will be described below with reference to Figure 1, along with Figures 7 and 8.

[0045] [Movable Unit 100"] The movable unit 100" is fixed to a predetermined height on the travel track 10 via a rail bracket 10b (not shown in Figure 2) fixed to the inner wall of the travel track 10. The height at which the movable unit 100" is fixed is the height at which the elevator car 11 is stopped when inspecting the elevator 1, and is the height corresponding to the regulating unit 200" provided on the elevator car 11. The rail bracket 10b may be the same one used to fix the guide rail 12 to the travel track 10, but it may also be a different type.

[0046] Such a movable unit 100" includes a shaft member 106", a fitting member 107", and a short connector 104, a first connector 105a, and a second connector 105b. The parts constituting the movable unit 100" will be described below.

[0047] -Shaft member 106”- The shaft member 106" is a cylindrical rotating shaft, fixed to the wall of the travel path 10 via the rail bracket 10b with its axis oriented in the direction of travel of the elevator car.

[0048] - Fitting member 107" - The fitting member 107" is a member that extends from the shaft member 106" perpendicularly to the shaft member 106". The tip position of the fitting member 107" is moved by the rotation of the shaft member 106". That is, the tip of the fitting member 107" has sufficient length to reach the regulating unit 200" which will be described later, from a state where it is on the wall side of the travel path 10 rather than the guide rail 12 (see Figure 7) (see Figure 8).

[0049] As shown in Figure 8, when the elevator car is stopped at a predetermined height, this fitting member 107" fits onto the restricting member 206" of the restricting unit 200" described next, thereby restricting the movement of the restricting member 206" and the elevator car 11 to which it is fixed. The tip of such a fitting member 107" has a shape that grips the restricting member 206" by pressing down on it from above, for example (see Figure 8).

[0050] Furthermore, the fitting member 107" is provided with bolt holes 107a" in the portion that clamps the regulating member 206" as needed.

[0051] -Short connector 104- The short connector 104 is similar to the one described in the first embodiment and is used to connect either the first connector 105a or the second connector 105b in an electrically connected state, and is inserted into either of these, for example. Such a short connector 104 is attached to the mating member 107" and moves between positions on either side of the shaft member 106" as the mating member 107" rotates.

[0052] -First connector 105a and second connector 105b- The first connector 105a and the second connector 105b are the same as those described in the first embodiment, and when the short connector 104 is inserted, they become electrically connected and transmit a signal indicating the connection state to the control panel 16.

[0053] Of these, the first connector 105a is fixed to the rail bracket 10b on the side of the travel path 10 wall that is closer to the travel path 10 than the shaft member 106". The first connector 105a allows the short connector 104 to be freely inserted when the tip of the fitting member 107" is positioned on the side of the travel path 10 wall due to the rotation of the shaft member 106". When the first connector 105a is connected, the control panel 16, which receives a signal from the first connector 105a, permits normal operation of the elevator 1. The control panel 16 also determines whether to permit or deny each operation by the operating unit installed, for example, inside the equipment box 4 or on top of the elevator car 11, based on the signal received from the first connector 105a.

[0054] Furthermore, the second connector 105b is fixed to the rail bracket 10b on the elevator car 11 side of the shaft member 106". When the tip of the fitting member 107" of the second connector 105b is positioned on the elevator car 11 side due to the rotation of the shaft member 106", the short connector 104 can be freely inserted. When the second connector 105b is connected, the control panel 16, which receives a signal from the second connector 105b, disables the normal operation of the elevator 1. The control panel 16 also determines whether to permit or deny each operation by the operating unit installed in the equipment box 4 or on top of the elevator car 11 based on the signal received from the second connector 105b.

[0055] [Regulatory Unit 200”] The regulating unit 200” is fixed to the elevator car 11, for example, via a crosshead 11c. Such a regulating unit 200” includes a regulating member 206”.

[0056] -Regulator 206”- The restricting member 206" fits into the fitting member 107" of the movable unit 100", thereby restricting the movement of the restricting member 206" and the elevator car 11 relative to the wall of the travel path 10 to which the fitting member 107" is fixed (see Figure 8). In the example shown in Figure 8, the restricting member 206" is a plate that fits into the fitting member 107" from below, and is pressed down from above by the fitting member 107", thereby restricting the upward movement of the elevator car 11.

[0057] Such a restricting member 206" is provided with a bolt hole 206a" in the portion that is clamped by the fitting member 107" when fitted with the fitting member 107" as needed. This allows a bolt 108" to be inserted through the bolt hole 107a" of the fitting member 107" and the bolt hole 206a" of the restricting member 206" and secured with a nut 109" when the fitting member 07" and the restricting member 206" are fitted together.

[0058] Furthermore, the restricting member 206" may be provided with a switch (not shown) at the portion that contacts the fitting member 107" when it is fitted with the fitting member 107"; this switch turns on when the fitting member 107" makes contact with the restricting member 206". The switch provided on the restricting member 206" is wired into the equipment box 4 on the elevator car 11, and the signal generated when the switch is turned on is transmitted from the equipment box 4 to the control panel 16. Therefore, the wiring route is short and simple. In this case, the short connect 104, the first connector 105a, and the second connector 105b provided on the movable unit 100 may be provided as needed.

[0059] <Effects of the Third Embodiment> Even in the third embodiment described above, the movable unit 100" for restricting the movement of the elevator car 11 is fixed to the travel path 10 side, and only the plate-shaped restricting member 206" is fixed to the elevator car 11. As a result, as in the first embodiment, the mass of the elevator car 11 can be reduced compared to the case where the movable unit 100" is fixed on the elevator car 11, and the mass of the counterweight 13 can also be reduced, thus reducing the product cost of the elevator 1. Furthermore, since the space occupied by the movable unit 100" when it is fixed on the elevator car 11 becomes available, it is also possible to secure workspace.
