A rotating shaft 3 is provided 10 to 50 cm inside from the opening end 11 and pivotally supports one end of the door 2.

  Then, when the car 1 arrives at the landing F and the door 2 opens, a part of the door 2 protrudes to the landing F beyond the car 1.

  The car 1 is a box-shaped member that stores luggage such as building materials and groceries and animals such as people and pets. And the opening part 12 for carrying out a luggage | load and an animal to the building side, or carrying in in the cage | basket | car 1 is provided. In the first embodiment and the second embodiment, the car 1 has a hollow rectangular parallelepiped shape. However, in other embodiments, a cubic shape, a cylindrical shape, or the like can be used.

  A wire rope W is fixed to the upper part of the car 1, and the length of the wire rope W between the hoist and the car 1 is adjusted by a hoisting machine (not shown) provided on the upper part of the hoistway A. The car 1 can be moved in the vertical direction in the hoistway A. Further, if necessary, a guide rail can be provided in the hoistway A that abuts the car 1 and prevents the car 1 from shaking in the horizontal direction and restricts the movement only in the vertical movement.

  The door 2 closes the opening 12 to prevent the luggage and animals from falling from the opening 12 of the car 1, and also removes the luggage and animals at the landing F or puts them in the car 1. It is a member which opens the opening part 12 in order to carry in. When the door 2 is opened, the door 2 is rotated around the rotation shaft 3 so as to protrude beyond the car 1 in a plan view and project to the landing F. Specifically, the door 2 is preferably a plate-like member and has a lateral width of 60 to 2000 cm. When the lateral width of the door 2 is within this range, the door 2 can be pushed out to the landing area F beyond the car 1 when the door 2 is rotated and opened. The door 2 preferably has a thickness of 20 to 100 mm. When the thickness of the door 2 is within this range, when the door 2 is open as shown in FIGS. 3, 5, 7, etc., the car 1 is raised or lowered due to the wire rope W being dropped or malfunctioning. Even if the door 2 interferes with the floor or ceiling of the landing area F, it is possible to secure a strength that can physically suppress the movement of the car 1, and the weight of the door 2 becomes too heavy. Therefore, energy such as electric power required for the vertical movement of the car 1 can be suppressed. In addition, as the material of the door 2, the door 2 interferes with the floor or ceiling of the landing area F even if the car 1 is dropped or malfunctioned due to breakage of the wire rope W, similarly to the thickness of the door 2. Thus, it is preferable to use a metal that is resistant to mechanical modification such as bending and twisting because the strength capable of physically suppressing the movement of the car 1 can be secured.

  And it is preferable that the door 2 has a height of 80 to 99% of the height in the vertical direction from the floor to the ceiling of the landing F of the building, and has a height of 85 to 95%. Preferably it is. If the height of the door 2 is in this range, even if the car 1 is dropped or malfunctioned due to breakage of the wire rope W when the door 2 is open, the door 2 is Since the movement of the car 1 is physically suppressed by interfering with the ceiling, and the vertical space between the opening 12 of the car 1 and the landing area F can be secured, the landing area F and the car 1 can be secured. Even when carrying or unloading luggage, it is prevented from being killed and injured by being caught between the car 1 and the boarding area F. Also, luggage loaded on the car 1, people on the board, pets, etc. Makes it easier to rescue animals.

  Moreover, the latching | locking part 21 is provided in the lower part of the other end side on the opposite side in the horizontal width direction with the one end pivotally supported with the rotating shaft 3 in the door 2. As shown in FIG. As shown in FIGS. 2, 3, and 5 to 7, in the first embodiment and the second embodiment, the locking portion 21 is a rod-like member that can move up and down manually or automatically. The locking portion 21 is raised so that the locking portion 21 does not come into contact with the floor of the car 1 when the door 2 is closed, and the locking portion 21 is at a predetermined place in the landing area F when the door 2 is open. The locking portion 21 is lowered so as to be inserted into the recess or the like. Specifically, the locking portion 21 is locked with the fitting hole 6 of the landing hall F in the first embodiment, and is engaged with the fitting hole 6 provided on the floor surface of the car 1 in the second embodiment. Can be stopped. By providing the locking part 21, if the locking part 21 is inserted into a depression or the like at a predetermined location such as the landing area F when the door 2 is open, when loading or unloading luggage, etc. Even if the door 2 does not close due to wind, shaking, etc., even if the car 1 is dropped or malfunctioned due to a breakage of the wire rope W, the door 2 interferes with the floor or ceiling of the landing F and the car The movement of 1 can be reliably suppressed.

  The rotation shaft 3 is a member that pivotally supports one end of the door 2 so that the door 2 can be opened and closed, and is provided 10 to 50 cm, more preferably 20 to 40 cm from the opening end 11 of the car 1. Yes. When the position of the rotating shaft 3 is slightly deeper than the opening end 11 as described above, the door 2 moves backward from the opening end 11 by about 10 to 50 cm so that it can be loaded on the car 1. Although the size and quantity of the luggage are limited, even when the luggage 1 is loaded or unloaded, even if the car 1 is lifted or lowered due to the wire rope W being broken or malfunctioning, it is separated from the rotating shaft 3. Since the lower end or upper end of the door 2 comes into contact with the floor or ceiling of the landing hall F, it becomes difficult for the impact due to the contact to be transmitted to the rotating shaft 3, so that the rotating shaft 3 is not easily damaged, and the car 1 is more than necessary. The storage space is not reduced. When the rotation shaft 3 is not easily damaged in this manner, the door 2 is difficult to be removed due to the impact of the contact, so that the door 2 itself becomes a bark and the vertical movement of the car 1 can be physically suppressed.

  Thus, depending on the opening / closing mechanism of the door 2 and the position where the rotation shaft 3 that pivotally supports the door 2 is provided, the car 1 may be inadvertently brought into or out of the car 1 by the operator Can prevent death or injury caused by movement. Furthermore, if the door 2 is rotated at the boarding / unloading hall F so that the door 2 extends beyond the car 1 to the boarding / unloading hall F, an operator who loads / unloads luggage into / from the car 1 uses a wire rope. Even if the door is lifted due to a fall or malfunction due to damage to W, it can be recognized at a glance that the door 2 is standing and the movement of the car 1 is suppressed, so that the safety device is attached in an invisible position. Compared to a transport machine, you can work with great peace of mind.

  As shown in FIG. 4, FIG. 5, etc., as the rotating shaft 3, a plurality of hinges can be used as the rotating shaft 3, and in other embodiments, a long hinge that is as high as the door 2 or the like. Can also be used. Further, the rotation shaft 3 may be attached to a columnar or plate-like support member 4 provided on the left and right of the opening 12 of the car 1, and a control panel is attached to the support member 4 so that the door 2 You may make it perform opening / closing and operation of the latching | locking part 21.

However, when the door 2 is open, even if the door 2 comes into contact with the floor or ceiling of the landing area F due to an unexpected movement of the car 1, the door 2 itself becomes a bark. Instead, it is preferable to provide a pair of doors on the left and right sides, which are a plurality of places, so as to form a double door. If comprised in this way, since the load concerning the door 2 will be disperse | distributed, the door 2 becomes difficult to be damaged.

  Moreover, as shown in FIG. 6, FIG. 7 which shows 2nd embodiment, the door 2 can also be provided and provided with a hinge in the middle of the door 2 so that protrusion at the boarding / alighting area F may be decreased. As shown in FIG. 7, when the door 2 is folded and opened, the door 2 does not unnecessarily protrude from the landing area F, so that the space of the landing area F can be used effectively and the door plate 4 Since the structure is such that the sheet protrudes from the car 1 to the boarding area F, when the car 1 is moved unexpectedly, the car 1 and the floor or ceiling of the boarding area F are firmly arranged. Since the load applied to the door 2 is dispersed, the door 2 is further hardly damaged. In the second embodiment, the configuration other than the door 2 is the same as that of the first embodiment.

  And as shown in each figure, it is preferable that the landing gate F is provided with an openable safety gate 5 that prevents the landing gate F from falling. The safety gate 5 preferably receives a signal via a sensor (not shown) that detects the arrival of the car 1 when it arrives at the landing F, and the gate is preferably opened automatically. Door 2 opens automatically or manually. At this time, the door 2 is opened to such an extent that it does not contact the safety gate 5. When there is a locking portion 21 at the lower part of the door 2, the impact when the locking portion 21 is lowered automatically or manually so as to be inserted into a depression or the like at a predetermined place such as the landing F or the like and the door 2 hits. Do not close with wind or wind.

  On the other hand, it is preferable that the safety gate 5 is also closed when the door 2 is closed automatically or manually after the loading or unloading of the luggage or the like is completed in the car 1. In this way, the safety gate 5 is interlocked with the movement of the car 1 and the opening and closing of the door 2, so that it is possible to prevent falling from the landing place F or contact with the car 1, etc. Can work.
