Description

Elevator gap clamping detection switch
Technical Field
The present invention relates to an elevator gap pinch detection switch, and more particularly, to an elevator gap pinch detection switch in which a switch body is provided in a space between an elevator door and an elevator wall, thereby preventing a part of a human body such as a finger from being sucked into the space along with the elevator door to prevent people from being injured when the elevator door is opened, and thus, assembly and maintenance are easier with a simpler structure.
Background
Generally, an elevator comprises: an elevator car which moves passengers in a vertical direction along a lifting passage formed in a vertical direction in a building in a state that the passengers are loaded in the elevator car; a motor and a winder for generating a prescribed power; and a control unit for controlling the motor and the winder according to the button operation of the passenger, so that the elevator cage moves to the corresponding floor.
The elevator car installed in the elevator apparatus has a car door that can be selectively opened and closed, and elevator landing doors that can be opened and closed in conjunction with the car door and allow passengers to get on and off at the corresponding floors are installed in the respective landing halls of the building.
In this case, a gap is formed between the floor frame and the elevator floor door to smoothly open and close the elevator floor door, and when a passenger waits in the waiting hall for boarding the elevator, the passenger does not get out of the elevator door without being aware of the opening of the elevator door in a state where the passenger has his or her hand around the gap of the elevator floor door, and the passenger is injured by being caught in the gap between the elevator floor door and the floor frame. In particular, in the case of children, attention is not sufficient, and therefore, there is a risk of a safety accident in which hands are caught between the floor frame and the elevator floor door and injured.
To solve such problems, Korean laid-open utility model No. 20-2010-0010939 was disclosed. The utility model relates to a hand clamping prevention device of an elevator, which is used for preventing hands of passengers or foreign matters from being clamped in an elevator landing door formed by arranging a car door and an elevator landing door in a fixed part consisting of an upper frame, a left side frame and a right side frame, a pair of upper frame left side sensor and upper frame right side sensor formed by an object reflection type sensor for emitting detection light in a vertical direction along a downward direction are respectively arranged on inner wall surfaces of both end portions of the upper frame corresponding to outer surfaces of the elevator landing door and the car door, a pair of upper frame center sensors formed by object reflection type sensors emitting detection light along the vertical direction towards the lower side are arranged on the inner wall surface of the upper frame center corresponding to the outer surfaces of the elevator landing door and the elevator car door, and when the elevator door is opened and closed, the hands of passengers, various foreign matters and the like can be prevented from being clamped.
However, the above-described utility model discloses a structure for detecting hands or foreign matters by detecting light, for example, in the case of an access door such as a box or a bag which does not affect the opening and closing of the door, the opening and closing of the door is controlled arbitrarily by detecting the above-mentioned situation, and therefore, the door opening and closing of the door which is mandatory in a specific situation becomes too frequent, which not only causes inconvenience to passengers, but also requires a plurality of sensors or the like to be provided in an upper frame or the like, and thus, the structure becomes complicated.
On the other hand, in order to solve the problem of the above utility model, japanese laid-open patent publication No. 2009-515798 is proposed. The present invention relates to a door assembly having a sensor made of a conductive film or the like on a surface or an edge surface of a door panel or a car front side wall panel, and having a sensor having the same structure also on a door frame.
Therefore, if the hand contacts with the surface or edge surface of the door panel or the front side wall plate of the car and the current of the human body is detected, the hand is prevented from being clamped between the elevator door and the frame and being injured by forcibly controlling the opening and closing of the door panel or the front side wall plate of the car. However, the above-mentioned utility model can only simply detect a human body to open and close the door to prevent injury, and does not provide visual information such as direct warning or emergency state to the door, so that in the case where the lamp is turned off due to a problem such as power failure in the elevator, a passenger may feel panic due to being unable to identify the position where the passenger is located.
On the other hand, in order to prevent leaning on the door or overload, according to "elevator equipment safety management law", a label printed with caution items such as "touch without hand", "leaning prohibited", and falling danger "is forcibly attached to a height of 170cm to 180cm from the lower ends of the elevator landing door and the car door of the elevator. However, since the car door and the elevator landing doors of all floors need to be attached after the aforementioned notice tag is manufactured, it takes much cost to attach a large number of notice tags, and also, it takes much cost for maintenance due to loss, damage, and the like of the attached notice tags, and much time is required due to labor input, and the aesthetic appearance of the elevator is also degraded.
Korean patent laid-open No. 10-1238068 for solving the problems of the safety device for preventing the grip of a door is disclosed. The invention relates to a safety device for preventing elevator door from clamping hands, which is characterized by comprising: a door conductive wave plate provided on a surface of an elevator door, which is opened and closed by a door driving motor controlled by a control unit according to a position between a car frame and a floor frame provided in an elevator car and a waiting hall, for detecting a current of a human body; a control unit for judging whether the current is micro current of human body if the current is detected by the conductive wave plate; and a first Light Emitting Diode (LED) provided on an edge side of the gate conductive wave plate, and configured to irradiate light to the gate conductive wave plate by being controlled by the control unit to be turned on. With this configuration, when the current of the human body is detected by the hand contacting the corner of the frame such as the elevator door or the elevator waiting hall, the elevator door is forcibly controlled to prevent the hand from being injured by the hand being caught between the elevator door and the frame, and the light is irradiated to the conductive waveguide sheet, so that the user can be visually alerted.
However, although the korean patent No. 10-1238068 has a problem in that a conductive wave plate may be provided on the surface of a door to irradiate light to the surface of the door, in a general elevator, in order to form a wide door through which a person can pass without hindrance, light of a light emitting diode provided on one side of a side surface of the door does not sufficiently reach the opposite side, and thus the amount of light irradiated to the surface of the door is low, and thus visibility is lowered as illuminance is lowered.
The structures for preventing the pinching disclosed in the above-mentioned patent documents have a problem that the structure is complicated and the structure is installed in the elevator in a large scale, so that the installation cost of the elevator is increased, which is not economical, and the passage of the elevator user may be disturbed after the installation.
In particular, the anti-pinch device for an elevator, which is applied to the known art, detects that a finger is pinched between the elevator and a wall body using a sensor, and thus, an additional structure such as a sensing part, a control part, and an inverter for converting a detection signal generated by the sensor and transmitting the converted signal to the control part is required, and thus, installation costs are increased, and the structure is complicated, and thus, if each structure is broken down, a lot of costs are required for maintenance.

Referring to fig. 1 to 7, the elevator gap pinching sensing switch according to the present invention includes a switch body 100 formed of a flexible material, having a predetermined space 101 formed therein, a protrusion 103 formed at a lower end of the space 101 to protrude in a direction of the space 101, and a left body 1021 and a right body 1022 separated from each other by a cut-out portion 104 with the protrusion 103 as a center, and connected to one side to open and close an interior of the switch, and positioned in each gap of front and rear doors of an elevator. As shown in fig. 3, the cross-sectional shape of the space 101 is a shape in which trapezoids are in contact with each other in opposite directions. Although the drawing shows that the protruding portion 103 is formed only on one side, it may be formed on both sides in a vertically symmetrical manner.
On the other hand, the switch body 100 is formed of a soft material such as silicon rubber or rubber, for example, in order to minimize the injury of fingers when the fingers are caught between the gaps of the elevator 200 and to easily conduct electricity by easily deforming and contacting with a conductor provided inside. The protrusion 103 is formed by joining inclined portions formed in an inclined manner to each other inside the switch main body 100, and the protrusion 103 is formed to play a role of buffering, and is easily restored to an original state when pressure is applied to the switch main body 100 by an external force, for example. At the same time, the conductors of different polarities described later can be brought into contact only with the intermediate portion of the conductor so as to be smoothly brought into contact with each other. The switch body 100 is divided into two parts, i.e., left and right parts, and the upper part is connected to the lower part in an open state, thereby forming a left body 1021 and a right body 1022. Further, as shown in fig. 4, since the protrusion 106 functioning as a hinge has elasticity, the left body 1021 and the right body 1022 can be spread out in the left and right directions.
On the other hand, the present invention includes a positive electrode first conductor 131 and a negative electrode second conductor 132 disposed so as to face each other on the inner surface of the space 101. Preferably, the first conductor 131 and the second conductor 132 are made of a material such as copper having excellent electrical conductivity as a copper plate.
The cross-sectional shape of the switch body 100 is a "shape", and the first conductor 131 and the second conductor 132 are attached to the inner surfaces of the switch body 100 at intervals in an opposing manner. As shown in fig. 6, the first conductor 131 and the second conductor 132 are connected to a control panel of an elevator by protruding a predetermined length from the upper end portions thereof. The upper end and the lower end are provided to prevent the first conductor 131 and the second conductor 132 from being in poor contact due to moisture or foreign matter entering the space 101. As shown in fig. 7, the switch main body 100 having the first conductor 131 and the second conductor 132 built therein may be formed in plural numbers and may be connected to each other for use. Therefore, the elevator door can be cut to an appropriate length to be used in a manner conforming to the length of the elevator door.
On the other hand, the present invention further includes a control unit (not shown) for stopping the driving of the elevator 200 and the elevator door 210 by detecting the above-mentioned condition when the conductors 131 and 132 are electrically conducted by the contact of the external force. The control part is electrically connected with a control panel for controlling the operation of the elevator door and the lifting motion of the elevator, when the first conductor 131 and the second conductor 132 are contacted with each other, if the current is switched on, a part of human body such as fingers or the like or objects are detected to be clamped in the gap between the elevator door to stop the driving of the elevator door or open the elevator door. Alternatively, the control unit may stop the elevator from moving up and down when the feet are caught between the elevator and the gaps above and below the elevator door. That is, as shown in fig. 3, when an external force is applied to the outside of the switch main body 100 to apply pressure, the first conductor 131 and the second conductor 132 are pressed toward the center of the switch main body 100 and conduct electricity with each other, thereby functioning as a switch.
On the other hand, the elevator gap pinching detection switch of the present invention shown in fig. 3a is provided at a small gap between the elevator doors, and in the case of the embodiment of fig. 3b, it is shown at a large gap between the elevator doors. That is, when a person gets on the elevator, the first conductor 131 and the second conductor 132 are in relatively good contact with the body of the human body, but since a part of the body having a small volume such as a finger may be sandwiched between the doors, as compared with the case shown in fig. 3a, a part of the upper end of the switch main body 100 is provided to protrude only from the cross section of the doors.
Meanwhile, the lower portion of the switch body 100 and the elevator door fixing member 120 configured to be able to receive a part of the lower portion of the switch body 100 are provided. The elevator door fixing member 120 has a protrusion 121 formed on an inner surface thereof, and a coupling groove 102 formed on an outer surface of a lower portion of the opening and closing body 100 at a position corresponding to the protrusion 121, thereby preventing the opening and closing body 100 inserted into the elevator door fixing member 120 from being separated outward.
On the other hand, the second embodiment of fig. 5 has exactly the same structure as the above-described embodiment of fig. 3 and 4. However, since the switch body 100 is formed of a relatively soft material, only when used in combination with the elevator door fixing member 120 is the additional reinforcing member 105 inserted to maintain the circular form of the switch body 100.
The procedure for detecting the presence of a gap in an elevator according to the present invention having the above-described structure will be described below.
Referring to fig. 4, the switch body 100 is divided into two parts with respect to the space 101, and is configured by forming a cut-out portion 104 cut out at one of both side ends, connecting the upper ends to each other, inserting and fixing the conductors 131 and 132 into the space 101, and then joining the cut-out portion 104.
As shown in fig. 3, in the switch body 100 into which each conductor is inserted, after the elevator door fixing member 120 as an additional member is coupled to an end of the elevator door 210 by bonding, screws, or the like and fixed, the switch body 100 is inserted into the elevator door fixing member 120 and fixed. In this case, the switch body 100 is firmly inserted into the elevator door fixing member 120 without being separated outward by the coupling groove 102 and the protrusion 121.
Hereinafter, the third to fifth embodiments are observed.
Fig. 8 is a plan sectional view schematically showing a state of a third embodiment of an elevator gap pinch detection switch according to the present invention, fig. 9 and 10 are views for explaining an assembly process of an internal structure of the elevator gap pinch detection switch of fig. 8, fig. 11 is a view showing a process of coupling the elevator gap pinch detection switch of fig. 8 with an elevator door, fig. 12 and 13 are views showing a fourth embodiment of the elevator gap pinch detection switch according to the present invention, and fig. 14 to 16 are views showing a fifth embodiment of the elevator gap pinch detection switch according to the present invention.
First, referring to fig. 8 to 13, the third and fourth embodiments of the electrode gap pinching sensing switch according to the present invention have the same configurations as those of the first and second embodiments described above. The shape of the space 101 and the switch main body 100 are not divided into left and right parts, but are divided into upper and lower parts by an upper main body 1023 and a lower main body 1024.
That is, as shown in fig. 8 to 10, the cross-sectional shape of the space 101 is a shape in which trapezoids are in contact with each other in opposite directions. Alternatively, as shown in fig. 9, the cross-sectional shape is a shape in which trapezoids are in contact with each other in the forward direction. The protrusion 103 is formed to have a buffering function, and is easily restored to an original state when a pressure is applied to the switch main body 100 by an external force, for example. At the same time, the conductors of different polarities described later can be brought into contact only with the intermediate portion of the conductor so as to be smoothly brought into contact with each other.
The present invention further includes a positive third conductor 133 and a negative fourth conductor 134 disposed to face each other on the inner surface of the space 101 of the switch main body 100. Preferably, the third conductor 133 and the fourth conductor 134 are made of a material such as copper having a good electric conductivity as a copper plate.
A support member 114 is attached to the rear surfaces of the third conductor 133 and the fourth conductor 134, and the support member 114 is attached to the rear surfaces of the third conductor 133 and the fourth conductor 134 to prevent the third conductor 133 and the fourth conductor 134 from being bent or broken. Therefore, it is preferable that the supporting member 114 is formed of Polycarbonate (PC) which is relatively less deformable and has flexibility. As a result, as shown in fig. 10, the conductors 134 and 134 to which the support member 114 is attached can be inserted from the top to the bottom and then joined so as to be easily fixed to the inner surface of the space 101.
The cross-sectional shape of the switch body 100 is a "shape", and the third conductor 133 and the fourth conductor 134 are attached to the inner surfaces of the switch body 100 spaced apart from each other so as to face each other. That is, as shown in fig. 8 to 10, in a state where the lower portion is closed and the upper end portion is opened, the third conductor 133 and the fourth conductor 134 protrude to the upper end portion by a predetermined length and are connected to the control panel of the elevator. As in the first and second embodiments, the upper and lower end portions are provided to prevent a contact failure of the third conductor 133 and the fourth conductor 134 due to inflow of moisture or foreign matter into the space 101. That is, the third conductor 133 and the fourth conductor 134 function as switches.
On the other hand, the configuration of the fifth embodiment of the elevator gap pinch detection switch according to the present invention is completely the same as the third embodiment and the fourth embodiment. However, the shape of the space 101 and the outer shape of the switch body 100 are somewhat different.
That is, as shown in fig. 14 to 16, the present invention includes the positive fifth conductors 135, which are arranged in order to be positioned inside the space 101, and the negative sixth conductors 136, which are positioned inside the upper body 1023 and are provided inside the lower body 1024, and are provided over the entire area of the lower body 1024. The sixth conductor 136 is made of a metal material such as aluminum, and when the switch body 100 is pressed, the fifth conductor 135 and the sixth conductor 136 are brought into contact with each other to conduct electricity, and the control unit stops the driving of the elevator 200 and the elevator door 210. The fifth embodiment is different from the above embodiments in that the cut-out portion 104 is not provided. The shape of the space and the shape of the sixth conductor 136 may be various shapes.
As described above, according to the elevator gap pinch detection switch of the present invention, the elevator gap pinch detection switch of the present invention can be easily inserted into the elevator door fixing member 120 and coupled to the elevator door fixing member only between the elevator and the wall body installed in the related art, and the first conductor and the second conductor are connected to the control unit for controlling the driving of the elevator, so that the facility becomes considerably simple. For example, conventionally, a sensor unit, a control unit, an inverter for converting a detection signal generated by the sensor and transmitting the converted detection signal to the control unit, and the like are required in order to prevent a finger from being pinched, but according to the present invention, the cost can be reduced to about 1/10, which is very economical.
In addition, since the gaps between the elevator and the wall body, that is, the gaps between the lobby 301 and the wall body and between the elevator car 302 and the elevator door, and the gaps between the upper and lower portions can be formed, the installation is easy, and particularly, in the case of the elevator installed in the related art, the elevator is installed in an attachment manner, and therefore, when a failure or maintenance occurs, it is only necessary to simply detach the elevator gap insertion detection switch and attach a new elevator gap insertion detection switch, and thus, the maintenance is very convenient.
The embodiments of the elevator gap pinch detection switch according to the present invention described above are merely exemplary embodiments, and those skilled in the art to which the present invention pertains can easily realize other specific embodiments without changing the technical idea or necessary features of the present invention. Therefore, it should be understood that the above-described embodiments are illustrative embodiments in all respects, and are not intended to limit the present invention. For example, the components described in the singular form may be dispersed and implemented, and similarly, the components described in the dispersed form may be implemented in a combined form.
The scope of the present invention is shown by the appended claims, and all changes and modifications that come within the meaning and range of the claims and the equivalent concepts thereof are intended to be embraced therein.
