And it was configured by connecting the emergency stop button 60 to the configured line (+) and the sub-line (-).

Hereinafter, the operation state and the effect according to the technical configuration of the present invention described above are as follows.

In order to operate the trunk doors 5 and 5 ′ configured as shown in FIGS. 3 to 5, the slide door (not shown) of the operation panel is opened with a key and the emergency stop button 60 in FIG. 6 is installed on the operation panel. And door button (5) and closing button (80) to operate the trunk door (5, 5 ') can be operated, so when using the elevator trunk (4) if necessary, open the slide door of the operation panel with a key When the button 70 is turned on, power is applied to the opening relay U coil through the contact B of the closing relay D and the opening limit switch 11, and the opening relay U is turned on. ON), the contact A (U1a, U2a, U3a) of the open relay U is turned on, and the contact B (U1b) is turned OFF.

Therefore, the open relay (U) is self-maintained by the contact A (U1a) to be on (ON) operation even if you release the release button 70, the motor 100 is the contact A of the open relay (U) ( Power is applied by U2a (U3a) to forward rotation, and the closing relay D is turned on even when the contact B of the opening relay U is turned off and the closing button 80 is pressed. You will not be able to.

That is, since the driven pulley 40 rotates by the chain 50 when the drive pulley 30 fixed to the motor shaft is rotated by the rotation of the motor 100 in FIGS. 3 to 5, the transfer female screw 15 The trunk door 5.5 'fixed to the transfer female screw 15 is guided to the door guide 14 attached to the car wall 1 while moving left and right by the rotation of the driven pulley 40 to move in the opening direction.

In this case, when the trunk doors 5 and 5 'are moved to the open position, when the opening limit switch 11 is operated by the switch cam 13 attached to the trunk door 5', the opening limit switch 11 in FIG. ) Is turned off to cut off the power applied to the self-sustained open relay (U). Therefore, the open relay U is turned off so that the contacts A (U1a, U2a, U3a) of the open relay U are turned off, and the contact B is turned on to stop the motor 100 that has rotated in the open direction, and the closed relay. (D) is a condition under which power can be applied by the operating state of the close button 80.

Power is applied to the coil of the closing relay D through the limit switch 12. Accordingly, the closing relay D is turned on so that the contacts A1, D2a, and D3a of the closing relay D are turned on, and the B contact D1b is turned off. Therefore, the closing relay (D) is self-maintained by the contact A (D1a) to operate on even if you remove the hand from the closing button 80, the motor 100 is the contact A (D2a, D3a of the closing relay D) The power is supplied through the reverse rotation in the closing direction, the open relay (U) is off the contact B (D1b) of the closing relay (D) is off, even if you press the open button 70 can not be turned on.

That is, since the driven pulley 40 rotates by a chain when the drive pulley 30 fixed to the motor shaft rotates by the rotation of the motor 100 in FIGS. 3 to 5, the feed female screw 15 follows the pulley. The trunk doors 5 and 5 'fixed to the transfer female screw 15 are guided to the door guide 14 attached to the car wall 1 while moving left and right by the rotation of the 40 and move in the closing direction.

At this time, when the closing limit switch 12 is operated by the switch cam 13 attached to the trunk door 5 'when the trunk doors 5 and 5' are moved to the closed position, the closing limit switch 12 of 6 degrees is turned off. The power applied to the self-holding closing relay D is cut off, the closing relay D is turned off, and the contacts A1, D1a, D2a, and D3a of the closing relay D are turned off, and the contact B1 is closed. The motor 100 that has been turned on and rotated in the closing direction is stopped, and the open relay U is a condition under which power can be applied by the open button 70, and the trunk doors 5 and 5 'are closed. It stops to finish the use of the trunk (4).

In addition, even when the trunk doors 5 and 5 'are opened or closed, pressing the emergency stop button 60 inside the operation panel (not shown) in the case of emergency may cause the rotation of the motor 100 to be positive and positive. It cuts off the power of phosphorus (-) and cuts off the power of the open relay (U) and the closed relay (D) which were self-maintained, and cuts off the power applied to the motor (100). The operation stops, and it is obvious that the trunk doors 5 and 5 'can be opened and closed again with the open and close buttons 70 and 80 in the inside of the control panel slider.

According to the trunk door opening and closing device of the trunk-mounted elevator of the present invention as described above, unlike the conventional device that needs to loosen and tighten the bolt nut every time the trunk is used, it is possible to automatically open and close the trunk door by driving the motor by the operation button. The trunk can be used conveniently, and the inconvenience of having to keep the separate trunk door separately can be eliminated. Only the specific person can operate the open / close button by opening the slide door of the operation panel with the key. Since the door can be opened and closed, there is an advantage of preventing the risk of entering the children's trunk in advance.
