Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator car operation panel, and more specifically, to locking and unlocking a case housing a switch provided on the back side of the car operation panel, equipment, etc. It concerns the lock structure.

[Prior Art] Fig. 7 is a schematic front view of an elevator car operation panel disclosed in, for example, Japanese Utility Model Application Publication No. 58-144568, viewed from the hall side, and Fig. 8 is a diagram showing A-A in Fig. 7. FIG. 7th
In Fig. 8, <la) is a nearly L-shaped panel;
(lb) is a button provided on the surface of panel (1), (12
) is a hinge fixed to the back of the panel (1) by welding, etc., and (2) is a case that houses switches, equipment, etc.
It is fixed to the hinge (12) with a bolt or the like, and a screw seat (6) is fixed to the opposing surface by welding or the like. (7)
is a cosmetic screw that is screwed into the screw of the screw seat (6) from the front side of the panel (1), and fixes the case (2>).<4>
It's a stupid door.

In the elevator operation panel configured as described above, when replacing or maintaining or inspecting the switches, equipment, etc. (not shown) housed in the case (2), use a screwdriver from the front side of the panel (1). Cosmetic screw (7) and screw seat (6)
), and then remove the panel (
Rotate 1) to open the case (2>).

[Problem to be solved by the invention] In the elevator car operation panel as described above, the panel (1
), and each time the case (2) is opened and closed, the cosmetic screw (7) must be tightened and released from this tightened state. This is troublesome, and since the head of the decorative screw (7) is exposed on the landing side, there is a problem that the design value is reduced.

In addition to the above-mentioned prior art related to such a car operation panel, for example, Japanese Patent Publication No. 55-39518, Japanese Utility Model Publication No. 58-180858, Japanese Utility Model Publication No. 59-25813, and Japanese Utility Model Publication No. 60-165355 A number of such issues have been disclosed, but all of them have problems, and it was hoped that they would be resolved quickly.

The present invention has been made to solve the above-mentioned problems, and it is possible to more easily lock and unlock the case when opening and closing it, and also eliminates the exposure of decorative screws on the panel surface. To obtain an elevator car operation panel that is easy to handle and has an excellent design.

[Means for Solving the Problems] The elevator car operation panel according to the present invention has a switch provided on the back side of the panel for operating the car, and a switch on the panel for locking/unlocking a case for storing equipment. A plurality of latches interlocked by rods on the back side, a plurality of locking pawls provided at the free end of the case to engage with the latches, and a panel provided at a position substantially opposite to one of these locking pawls to engage the latch when the lock is locked. The car door is equipped with a rotary lever that is engaged with the car door, and a cam that is provided on the end face of the car door and interferes with the rotary lever when the car door moves in the closing direction.

[Function] The lock can be reliably locked by engaging the latch and the locking pawl. In addition, when unlocking the car door, when the car door is moved in the closing direction, the lever can be inserted into the gap between the car door and the panel and the rotary lever can be operated to easily disengage the latch and the locking pawl. I can do it.

[Embodiment] Figs. 1 to 6 show an elevator car operation panel according to an embodiment of the present invention, in which Fig. 1 is a schematic front view seen from the landing side, and Fig. 2 is a car door. BB sectional view of FIG. 1 when the elevator door is moving in the opening direction, FIG. 3 BB sectional view of FIG. 1 when the basket door is moving in the closing direction,
The drawings are a sectional view taken along the line CC in FIG. 3, FIG. 5 is a perspective view showing details around the rotary lever, and FIG. 6 is a perspective view showing the state of engagement between the lever and the latch.

In Figures 1 to 6, (1) is a panel with a rectangular cross section, (11> is a mounting frame provided on the inside of panel (1) on the entrance/exit side, and (12) is the back side of panel (1). The hinge (2) is attached to the hinge (12) by welding or the like, and is a case that houses switches, equipment, etc., and is fixed to the hinge (12) with bolts, etc., and the hinge (12) has locking claws (2) at diagonal positions.
1) and (21a) are attached with bolts or the like. (13) is a nearly U-shaped mounting bracket fixed to the end of panel (1), and (14) is fixed between arms (13a) and (13b) provided above and below the mounting bracket (13). shaft,(
13c) is a stopper provided on the arm (13b). (1
5) is a rotary lever that is integrally configured with a plate-shaped upper lever (15a) and an L-shaped lower lever (15b), and is rotatably attached to the shaft (14).
) is a torsion compression spring (1) interposed between the shaft (14) and the shaft (14).
6>, it is constantly pressed down and a rotational force in the opposite direction of the arrow is applied (FIGS. 2 and 5).

(3) and (3a) are shafts (31) fixed to the mounting frame (11).

(31a) respectively rotatably mounted latches, (31a);
32) is a leg fixed to the latch (3a), and the latch (3), (3a) is always rotated clockwise ( The rotational force of both latches (Fig. 4) is applied, and both latches (
3) The - ends of (3a) are connected by a rod (17). (18) is a stopper that restricts rotation of the latch (3). (4) a car door; (41) a cam plate attached to the end of the car door (4); and (5) a release lever.

In the present invention configured as described above, the latch (3) provided on the mounting frame (11) provided on the entrance/exit side of the panel (])
, (3a) are biased by the tension springs (33) and (33a) and rotate clockwise around the supports (31) and (31a), respectively, and when the panel (1) is closed, the solid line in Fig. 4 appears. The locking claw (21) fixed to the case (2) as shown in
(21a) and is locked. At this time, the rotation of the latch (3) is regulated by the stopper (18>), and the latch (3a) connected by the rod (17) is also positioned at that position. The lever (15a) is in contact with the panel (1) as shown in Fig. 2 due to the action of the torsion spring (16), but when the car door (4) closes, the cam plate (41) ), rotate it in the direction of the arrow in Figure 2 and position it under the leg (32) provided on the latch (3b), and the upper lever (15a) protrudes toward the car door (4) ( Figures 3 and 5).

To unlock the latches (3) and (3a), as shown in Figures 3 and 6, remove the lever from between the car door (4) and the panel (1) when the car door (4) is closed. (5>
, and using the cam plate (41) as a fulcrum, remove the lever <5.
> is pushed upward and the upper lever (15a) protruding toward the car door (4) is pushed up, the lower lever (15b) formed integrally with this is also displaced upward, as shown in Fig. 4. Push up the leg (32) to release the latch (3),
(3a) and the locking claws (21), (21a) are disengaged and unlocked. As a result, the case (3) can be opened by rotating the panel (1) around the hinge (12) in the direction of the arrow. If the release lever (5) is removed, the rotation lever (15) can be twisted and compressed by the compression spring ( 16) returns to the original state.

[Effects of the Invention] As described above, according to the present invention, a plurality of latches and locking claws are engaged with each other to lock a panel in a case housing car operation switches and equipment, and also lock a car operation switch and a case housing devices. Since the rotary lever is activated to unlock the door when the door is moved in the closing direction, the panel can be reliably locked and unlocked easily. Furthermore, since the decorative screws for fastening the case to the panel are not exposed on the panel surface side, the design as seen from the landing side can be improved.
