Abstract

PURPOSE: To prevent a member unrelated to a cage operation part from being projected from a surface of a swing return panel by turning a working shaft from a lower end side of the swing return panel. CONSTITUTION: A substantially L-shaped member 13 to be engaged is engageable with a cutout part of an engagement member 10, and the member 13 is fixed to a fitting wall of a wing well. A tension spring 14 is stretched between the tip side of the engagement member 10 and a support pat 7a, and the engagement member 10 is urged toward the member 13. When a cage operation part assembled with a swing return panel 1 is inspected, a hexagon head wrench 16 is fitted to a recessed part 8a in a working shaft 8 to turn the working shaft 8, and a working pin 12 is moved along an inclined surface of a cam to press a working piece 11 downward. When the working piece 11 is pressed, the engagement member 10 is turned around a support shaft 10c to be engaged from the member 13. Then, the swing return panel 1 is unlocked.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock device for locking a swing return panel provided on a sleeve wall of an elevator cab.

[0002]

2. Description of the Related Art As shown in FIG. 7, a swing return panel 102 is provided on a sleeve wall 101 of an elevator cab so that the swing return panel 102 can be opened and closed. The car operation unit 103 is incorporated, and this car operation unit 103 is a destination floor instruction button 103a for instructing the destination floor of the car.
And so on. One end side (left end side in FIG. 7) of the swing return panel 103 is attached to the side wall 104 via a hinge (not shown), and the swing return panel 103 is closed at the other end side (right end side in FIG. 7). A lock portion 105 (shown in FIGS. 8 and 9) that locks in the closed state is attached. That is, a swing shaft 106 is provided on the other end side of the swing return panel 102, and an engagement piece 107 is fixed to the rotation shaft 106.
7 is engageable with an engaged portion 108 formed on the sleeve wall 101. When the engaging piece 107 engages with the engaged portion 108,
The swing return panel 102 is locked in the closed state.

In order to inspect the car operation unit 105, the rotary shaft 10 protruding from the surface of the swing return panel 102 is checked.
When 6 is rotated by a driver or the like, the engagement piece 107 is disengaged from the engaged portion 108 and the locked state is released. next,
The swing return panel 102 is opened, and the car operation unit 105 incorporated therein is inspected.

[0004]

In such a conventional swing return panel locking device, the rotary shaft 1 is used.
No. 06 had to be taken out from the surface of the swing return panel 102 in order to be turned by a driver. As described above, if the rotating shaft 106, which is not related to the car operation unit 105, is projected from the surface of the swing return panel 102, it is somewhat aesthetically problematic.

It is an object of the present invention to provide a swing return panel lock device in which a member unrelated to the car operation part is not exposed from the surface of the swing return panel.

[0006]

In order to achieve such an object, according to the present invention, a swing return panel which is provided on a sleeve wall so as to be openable and closable and is located relatively closer to the inside of a car than a kick plate is. An operating shaft rotatably provided on the back side of the swing return panel, an engagement member operably attached to the back side of the swing return panel, and the engagement member provided on the sleeve wall side. Engaged member that locks the swing return panel in the closed state when engaged with, and cam means that releases the engaged state with the engaged member by operating the engaging member by rotating the operating shaft. And a structure in which the operating shaft can be rotated from the lower end side of the swing return panel.

[0007]

When the car operation part incorporated in the swing return panel is inspected, a hexagon wrench or the like is brought to the lower end side of the swing return panel and the hexagon wrench is fitted to the operating shaft. Turning the actuating shaft with a hexagon wrench actuates the cam means. When the cam means is actuated, the engagement member rotates and is disengaged from the engaged member. Then, the swing return panel is unlocked.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 to 6 are views showing an embodiment of a lock device for a swing return panel according to the present invention.

In FIG. 6, reference numeral 1 denotes a swing return panel which is provided on a sleeve wall 2 of a car room of an elevator so as to be openable and closable. The swing return panel 1 incorporates a car operation unit 3 for operating the elevator. Has been. The car operation unit 3 has a destination floor instruction button 3a and the like.

As shown in FIG. 1, a hinge 4 is attached to one end of the swing return panel 1 and is rotatably supported by a side wall 5 of the cab through the hinge 4. Further, a lock device 6 for locking the swing return panel 1 in a closed state is provided on the other end side of the swing return panel 1.

As shown in FIGS. 2 and 3, a support bracket 7 having a substantially L-shaped cross section is fixedly attached to the back side of the swing return panel 1, and a support portion 7a of the support bracket 7 has an operating shaft 8 attached thereto. Are rotatably supported via a support block 9. Further, the engagement member 10 is rotatably supported on the support portion 7a via a support shaft 10c.

As shown in FIG. 4, the engaging member 10 has a sloped portion 10a formed on the tip end side, and a cutout portion 10b is formed adjacent to the sloped portion 10a. An operating piece 11 having a cam slope 11a is provided on the base end side of the engaging member 10.
Is fixed, and the operating pin 12 planted on the operating shaft 8 is in contact with the cam slope 11a. The operating piece 1
1 and the operating pin 12 constitute a cam means.

A notched portion 10b of the engaging member 10 is engageable with an engaged member 13 having a substantially L-shaped cross section, and the engaged member 13 is fixed to a mounting wall surface 2a of the sleeve wall 2. .
A tension spring 14 is stretched between the tip end side of the engaging member 10 and the support portion 7a, and biases the engaging member 10 toward the engaged member 13.

A kick plate 15 is located below the swing return panel 1 as shown in FIG. The swing return panel 1 is positioned relatively to the inside of the car with respect to the kick plate 15, and a step is formed between them. Therefore, as shown in FIG. 5, the operating shaft 8 can be seen between the swing return panel 1 and the kick plate 15. The lower end of the operating shaft 8 has a hexagonal concave portion 8 that can be engaged with the hexagonal wrench 16.
a is formed.

When inspecting the car operation part 3 incorporated in the swing return panel 1, as shown in FIG. 2, a hexagon wrench 16 is brought to the lower end side of the swing return panel 1 and operated by the hexagon wrench 16. The shaft 8 is fitted into the recess 8a. Actuator shaft 8 with hexagon wrench 16
When is turned, the operating pin 12 moves along the cam slope 11a, pushing the operating piece 11 downward. When the operating piece 11 is pushed, the engaging member 10 rotates about the support shaft 10c and is disengaged from the engaged member 13. Then, the locked state of the swing return panel 1 is released. Next, FIG.
Open the swing return panel 1 as shown in, and inspect the car operation unit 3.

[0016]

As described above, according to the present invention,
Since the operating shaft can be rotated from the lower end side of the swing return panel, it is not necessary to take out the member of the lock device from the surface of the swing return panel as in the conventional case, which is excellent in appearance. .
