Description

  The present invention relates to an apparatus for restricting entry into an elevator, and more particularly to an apparatus for restricting pressing of a call button of an elevator.

  In an apartment house or the like, for example, an auto-lock system is adopted for a common entrance of a building. At the joint entrance of the auto lock, residents can unlock the auto lock and enter the building. Visitors can enter the building by, for example, communicating with each dwelling unit using an intercom linked with each dwelling unit and having the resident release the auto-lock. Residents and visitors can enter the building and then press the call button on the elevator floor on the lobby floor to arrive at the car and get on the car to reach the entrance on the destination floor.

  In such a housing complex, an outsider may intrude into the building following the resident or a visitor authorized by the resident when auto-locking the common entrance. In this case, there is a problem that the outsider can get into the car that has arrived by pressing the call button at the elevator hall, and the outsider can enter the front of the dwelling unit.

  Various methods for restricting the entry of outsiders into the elevator have been proposed for such problems (see, for example, Patent Document 1). Patent Document 1 discloses an apparatus that controls the operation of an elevator so that an elevator door is opened only when a predetermined input is input to an input device such as a numeric keypad or a non-contact key reader at an elevator landing. ing. According to such a method, it is possible to prohibit outsiders from getting into the elevator. Such an apparatus for restricting entry into an elevator is generally introduced at the time of new construction or when an elevator is updated.

  Even in an existing elevator facility, there is a case where it is desired to add a function related to the restriction on the elevator as described above. However, the elevator entry restriction device disclosed in Patent Document 1 requires an input device such as a numeric keypad or a non-contact key reader to be installed at the elevator platform, and based on an input signal to the input device. It is necessary to rearrange the elevator control program to control the operation of the elevator. Therefore, when adding the function concerning the above-mentioned boarding restrictions to the existing elevator installation, introduction cost will become expensive.

  Further, in elderly facilities and hospitals, there is a need to add the above-described boarding restriction function even at the elevator platform on each floor. If the above-described boarding restriction device is installed at the elevator hall on each floor, the introduction cost is further increased, which is not appropriate.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings.

  1 to 7 show an example of a call button press restriction device according to the present invention. As shown in FIGS. 1 and 2, the call button press restriction device A1 of this embodiment includes two operation buttons 1 and 1 and an operation button restriction mechanism for restricting the movement of these operation buttons 1 and 1. 2 and is used by being attached to an indicator plate 5 provided at an elevator landing.

  The indicator plate 5 is provided with a call button 51 for calling an elevator car. For example, the indicator plate 5 shown in FIG. 1 is provided in an elevator landing on each floor of a building. For example, the indicator plate 5 can be pressed to distinguish two directions of an upper floor and a lower floor as destinations. Two call buttons 51, 51 are provided.

  The operation button 1 and the operation button restriction mechanism 2 are accommodated in a case 3, and the case 3 is attached so as to cover the indicator plate 5. Although details will be described later, in the present embodiment, the case 3 is provided with four locking claws 33, and these locking claws 33 are fitted in the notches 5a formed in the indicator plate 5 (see FIG. 7). Thus, the case 3 can be attached. The notch 5a is provided for easily removing the indicator plate 5 during maintenance.

  The case 3 has a substantially rectangular parallelepiped shape, and includes a base body 31 and a cover body 32 that covers the base body 31. The base body 31 has a long rectangular bottom wall 311 and side walls 312 rising from appropriate positions around the bottom wall 311. The base body 31 is provided with operation buttons 1 and 1 arranged in the longitudinal direction. The bottom wall 311 is provided with a pair of standing walls 313 and 313, and each operation button 1 is disposed between the pair of standing walls 313 and 313. Openings 311 a and 311 a for allowing the operation buttons 1 and 1 to appear and disappear are formed in the bottom wall 311.

  The operation buttons 1 and 1 are provided so as to cover the call buttons 51 and 51. Each operation button 1 is moved away from the call button 51 (see FIG. 3), and a push-down position (see FIG. 6) that advances to the direction z (first direction) on the call button 51 side and presses the call button 51. ).

  In the present embodiment, each operation button 1 is supported at the end of the standing wall 313 so as to be rotatable around the rotation axis O1. The rotation axis O1 extends in a direction x (second direction) perpendicular to the direction z. Thereby, the operation button 1 can be displaced in the direction z by a rotation operation around the rotation axis O1.

  Each operation button 1 is provided with a protruding plate portion 11. The protruding plate portion 11 protrudes in a direction y that is perpendicular to both the direction z and the direction x at the end away from the rotation axis O1. The protruding plate portion 11 is provided in the middle of the thickness direction (direction z) of the operation button 1 and extends along a direction x that is parallel to the rotation axis O1.

  A compression coil spring 12 is provided at an appropriate position of the protruding plate portion 11. The compression coil spring 12 applies a biasing force in a direction (opposite to the direction z) in which the operation button 1 is rotated from the pressed position toward the retracted position, and one end thereof is fixed to the protruding plate portion 11. The other end is in contact with the bottom wall 311. Due to the compression coil spring 12, each operation button 1 is in the retracted position in a state where no external force is applied. On the other hand, when the top of the operation button 1 is pressed and the operation button 1 is rotated and displaced in the direction z, the bottom of the operation button 1 appears and disappears from the opening 311a. At this time, the operation button 1 is in a pressed position where the operation button 1 advances to the call button 51 side and presses the call button 51.

  Each protruding plate portion 11 is formed with a slit 111 penetrating in the thickness direction (direction z) of the operation button 1. The slit 111 is an intermediate portion in the direction x of the protruding plate portion 11 and is a portion into which a locking portion 211 of the lock member 12 described later enters. The significance of the slit 111 will be described later.

  As shown in FIG. 3, in the present embodiment, each operation button 1 is formed with a through hole 1 a penetrating in the thickness direction (direction z). The through hole 1a has a relatively small size with a cross-sectional diameter of about 3 mm. The significance of the through hole 1a will be described later.

  The operation button restriction mechanism 2 switches between a locked state in which the displacement of each operation button 1 from the retracted position to the pressed position is not permitted and an unlocked state in which the displacement of each operation button 1 from the retracted position to the pressed position is permitted. In this embodiment, the lock member 21 and the solenoid 22 are provided.

  As shown in FIG. 2, the lock member 21 is positioned outside the protruding plate portion 11 of the operation button 1 (on the right side in FIG. 2) and has a plate shape extending in the direction x adjacent to the side wall 312. ing. The lock member 21 is provided with locking portions 211 and 211 that protrude toward the operation buttons 1 and 1. Each locking part 211 is in a position overlapping the protruding plate part 11 of the operation button 1 in the direction z. The distance in the direction x of the locking portions 211 and 211 is substantially the same as the distance in the direction x of the slits 111 and 111.

  One end of the lock member 21 is connected to the actuator 221 of the solenoid 22. The lock member 21 is moved along the direction x in accordance with the movement of the actuator 221 and is movable between a lock position (see FIG. 2) and a lock release position (see FIG. 5). One end of the tension coil spring 23 is connected to the other end of the lock member 21, and the other end of the tension coil spring 23 is supported by the side wall 312 via the shaft 24.

  When the lock member 21 is in the lock position shown in FIG. 2, the slit 111 of the operation button 1 and the engaging portion 211 of the lock member 21 are in a position shifted in the direction z. Therefore, when the operation button 1 is pressed from the retracted position toward the pressed position, as shown in FIG. 4, the protruding plate portion of the operation button 1 is on the movement path from the retracted position to the pressed position. 11 abuts on the locking portion 211 of the lock member 21 to prevent the operation button 1 from moving. When the protruding plate portion 11 comes into contact with the locking portion 211, the bottom portion of the operation button 1 does not protrude from the opening 311a, and the call button 51 is not pressed. At this time, the operation button restriction mechanism 2 is in a locked state.

  When the lock member 21 is in the unlocked position shown in FIG. 5, the slit 111 of the operation button 1 and the locking portion 211 of the lock member 21 are in a position where they overlap in the direction z. For this reason, when the operation button 1 is pressed from the retracted position toward the pressed position, as shown in FIG. 6, the locking portion 211 enters the slit 111 of the protruding plate portion 11, and the operation button 1 is moved to the pressed position. Pushed in. As described above, the protruding plate portion 11 of the operation button 1 does not come into contact with the locking portion 211 of the lock member 21 in the movement path from the retracted position to the pressed position. At this time, the operation button restriction mechanism 2 is in the unlocked state.

  The solenoid 22 is for moving the lock member 21 between the lock position and the lock release position. When the solenoid 22 is not energized, as shown in FIG. 2, the actuator 221 is pulled out in the direction x side by the elastic restoring force of the tension coil spring 23, and the lock member 21 assumes the lock position. At this time, as described above, the call button 51 is not pressed by the operation button 1. On the other hand, when the solenoid 22 is energized, as shown in FIG. 5, the actuator 221 is drawn into the solenoid 22, and the lock member 21 takes the unlocking position. At this time, as described above, the operation button 1 can be pushed down to the pressed position.

  In the present embodiment, an LED lamp 35 (display unit) for indicating the energized state of the solenoid 22 is provided in the case 3. The LED lamp 35 is supported by the bottom wall 311 of the base body 31 and lights up only when the solenoid 22 is energized.

  As shown in FIG. 2, the four locking claws 33 provided on the case 3 are paired left and right (direction y in FIG. 2), and the left and right pairs are separated vertically (direction x in FIG. 2). doing. The locking claws 33, 33 that form a pair on the left and right sides are connected to each other by a set screw 34, and the distal end side protrudes to the outside through the opening portion of the side wall 312. As clearly shown in FIG. 7, a through hole 331 through which the screw portion of the set screw 34 is inserted is formed at the base end portion of one locking claw 33, and the base end portion of the other locking claw 33 is formed. A screw hole 332 for screwing the screw portion of the set screw 34 is formed. According to such a configuration, it is possible to adjust the distance between the front ends of both the locking claws 33, 33 by turning the set screw 34.

  When attaching the case 3 to the indicator plate 5, first, the set screw 34 is loosened, and the tip hook portions of the locking claws 33, 33 are made to face the notch 5 a of the indicator plate 5. Next, the set screw 34 is tightened, and the tip of the locking claw 33 is fitted into the notch 5a. In this way, the case 3 (base body 31) can be attached to the indicator plate 5. The set screw 34 is operated with the cover 32 removed.

  The cover body 32 has a long rectangular top wall 321 and a side wall 322 that rises from an appropriate position around the top wall 321. A decorative plate 323 is provided on the outer surface of the top wall 321. The top wall 321 and the decorative plate 323 are formed with openings 32a and 32a in which the tops of the operation buttons 1 and 1 face outward and a through hole 32b for making the LED lamp 35 visible from the outside. Attachment of the cover body 32 to the base body 31 is performed by appropriate means such as screwing in a state where the top wall 321 is covered so as to face the bottom wall 311 of the base body 31.

  The call button press restriction device A1 according to the present embodiment is installed, for example, in an elderly facility or a hospital, and is controlled by a controller (not shown) disposed on a wall near the place where the call button press restriction device A1 is installed. The For example, a power supply line and a signal line (not shown) are connected to the call button press restriction device A1, and the operation button restriction mechanism 2 (solenoid 22) is controlled based on a control signal from the controller.

  The controller includes a signal input device such as a numeric keypad input device or a non-contact key reader, and controls the operation button limiting mechanism 2 (solenoid 22) based on an input signal to the signal input device by an elevator user. To do. When an appropriate signal is input to the signal input device, the controller switches the operation button control mechanism 2 (solenoid 22) from the locked state to the unlocked state based on the signal from the signal input device. That is, the controller outputs a control signal for turning on the energization of the solenoid 22. When the solenoid 22 is energized, the call button 51 can be pressed by pressing the operation button 1 to the pressed position as described above. When a predetermined time has elapsed from the start of energization of the solenoid 22, the energization of the solenoid 22 is cut off. Then, the operation button restriction mechanism 2 returns from the unlocked state to the locked state. The operation modes of the lock member 21 and the operation button 1 when the solenoid 22 is not energized and when energized are as described above with reference to FIGS. The controller is configured by an electronic circuit including a microcomputer, for example, and can control the operation button restriction mechanism 2.

  Next, the operation of the call button press restriction device A1 will be described.

  As described above, the call button restriction device A1 (operation button restriction mechanism 2) of the present embodiment has a locked state in which the call button 51 of the elevator cannot be pressed and an unlocked state in which the call button 51 can be pushed. It can be switched. The operation button 1 cannot be pushed in unless the operation button restriction mechanism 2 is switched from the locked state to the unlocked state. According to such a configuration, it is possible to restrict the entry of the elevator by restricting the person who is given the authority to release the lock. For example, in an elderly facility or a hospital, the use of an elevator by an unintended resident or hospitalized patient can be prevented by giving an unlocking authority only to a predetermined manager.

  According to the call button press restriction device A1, the boarding of the elevator can be restricted by covering the elevator call button 51 so as to cover it. For this reason, it is possible to add a function related to boarding restrictions to an existing elevator at a relatively low cost without changing the elevator control program. Therefore, the call button press restriction device A1 is suitable for introduction into an existing elevator facility.

  The operation button restriction mechanism 2 includes a lock member 21 that is movable between a lock position and a lock release position. Then, by changing the position of the lock member 21, a locked state in which the displacement of the operation button 1 from the retracted position to the pressed position is not permitted, and an unlocked state in which the displacement of the operation button 1 from the retracted position to the pressed position is permitted. And can be switched. According to such a configuration, switching between the locked state and the unlocked state in the operation button limiting mechanism 2 can be realized with a relatively simple structure.

  Further, the movement of the lock member 21 between the lock position and the lock release position can be appropriately performed by switching between the non-energization and the energization of the solenoid 22.

  Further, in the present embodiment, an LED lamp 35 for indicating the energized state of the solenoid 22 is provided. For this reason, it can be easily grasped from the outside whether the operation button restriction mechanism 2 is in the locked state or the unlocked state.

  The operation button 1 is supported so as to be rotatable about a rotation axis O1 extending in a predetermined direction, and a biasing force in a direction of rotating from the pressed position toward the retracted position is applied by the compression coil spring 12. . According to such a configuration, the operation button 1 can be normally displaced between the retracted position and the pressed position while being displaceable.

  The operation button 1 is formed with a through hole 1a penetrating in the thickness direction (direction z). Thereby, even if some troubles occur in the operation button restriction mechanism 2 and it cannot be brought into the unlocked state, for example, the call button 51 can be pushed by pushing it through the pin into the through hole 1a.

  FIG. 8 shows another example of a call button press restriction device according to the present invention. In the figure, elements that are the same as or similar to those in the above embodiment are given the same reference numerals as in the above embodiment, and description thereof will be omitted as appropriate.

  The call button press restriction device A2 of the present embodiment is additionally provided with a numeric keypad input device 4, a control unit 41, and a battery 42, and is different from the call button press restriction device A1 of the above embodiment in this respect. ing. The numeric keypad input device 4 is an example of the signal input means referred to in the present invention, and is for inputting a personal identification number, for example. The control unit 41 is for switching the operation button restriction mechanism 2 from the locked state to the unlocked state based on the input signal from the numeric keypad input device 4. The battery 42 supplies driving power for the solenoid 22 and the like. These numeric keypad input device 4, control unit 41, and battery 42 are accommodated inside case 3. The numeric keypad input device 4, the control unit 41, the battery 42, the solenoid 22 and the like are appropriately connected by power supply lines and signal lines. As for the numeric keypad input device 4, each input key appears and disappears from the cover body 32, and an input operation is possible.

  In the call button press restriction device A2 of the present embodiment, the operation button restriction mechanism 2 (solenoid 22) is controlled based on an input signal to the numeric keypad input device 4. When the correct password (appropriate signal) is input to the numeric keypad input device 4 by the elevator user, the control unit 41 locks the operation button control mechanism 2 (solenoid 22) based on the signal from the numeric keypad input device 4. Switch from state to unlock state. That is, the control unit 41 outputs a control signal for turning on the energization of the solenoid 22. When the solenoid 22 is energized, the call button 51 can be pressed by pressing the operation button 1 to the pressed position as described above. When a predetermined time has elapsed from the start of energization of the solenoid 22, the energization of the solenoid 22 is cut off. Then, the operation button restriction mechanism 2 returns from the unlocked state to the locked state.

  According to the call button restriction device A2 of the present embodiment, since it is not necessary to supply a control signal or power from the outside, the introduction cost can be reduced.

  The call button press restriction device according to the present invention is not limited to the above-described embodiment. The specific configuration of each part of the call button press restriction device according to the present invention can be varied in design in various ways.

  In the above embodiment, the case where the two operation buttons 1 and 1 are provided has been described as an example, but the present invention is not limited to this. For example, in an elevator hall at a common entrance of an apartment house, generally, only a call button on the upper floor is provided as a destination, and for a call button press restriction device installed for such a call button, one operation is performed. It is good also as a structure which comprises a button. Moreover, it can also be set as the structure which comprises three or more operation buttons as needed.

  In the above embodiment, the call button press restriction device A1 is attached using the notch 5a of the indicator plate 5, but is not limited thereto. The call button press restriction device can be attached using other means such as double-sided adhesive tape or screw fixing. Moreover, it does not necessarily need to attach with respect to the indicator plate 5, and you may attach to the wall surface provided with the indicator plate.
