Description

Elevator Protection Safety System Using Motion Sensor

The present invention relates to a safety device for preventing jamming in an elevator using a motion sensor, and when a platform door and elevator door are opened and closed, when a motion of a person or an object is detected at the opening and closing point of the door, the platform door is reopened, and also the platform door and the platform It relates to a device that stops the opening and closing of the elevator door and the elevator door when a body jamming is detected between the frames or in the gap between the elevator door and the elevator wall, and safety measures are taken.

More specifically, the elevator jamming prevention safety device using the motion sensor of the present invention is linearly provided in the longitudinal direction adjacent to the platform door on one side of the platform frame, and it is possible to detect that the body is caught between the platform door and the platform frame. The presence detection unit is provided linearly in the longitudinal direction, divided into one side and the other side along the longitudinal direction, and a current sensing unit or laser sensing unit capable of detecting jamming is provided on one side facing the platform door, and the jamming detecting unit is provided on the platform frame on the other side. A support part that can be fixed is configured, and a motion sensor capable of detecting the motion of a person or an object is provided as a motion detection part at the bottom of the safety device in a rotatable form as a motion sensing part to sense a movement toward the platform. Checks whether a person or object is moving and, if a motion is detected, sends a motion detection signal to the control unit to open the platform door so that safety measures can be taken. Elevator trapping prevention using motion sensor that detects jamming by means of current passing through the deformation of the jamming sensing part or blocking the laser light reception and transmitting it to the control unit to stop the operation of the elevator and take safety measures It's about safety.

In general, an elevator includes an elevator car that moves passengers while moving up and down along a hoistway formed in a vertical direction inside a building while a passenger is on board, a motor and a hoisting machine that generates a predetermined power, and a button operation of the passenger according to the control means for controlling the motor and the hoisting machine to move the elevator car to the corresponding floor and the like.

In addition, the elevator car provided in the elevator device is provided with a car door that can be selectively opened and closed, and a platform door that opens and closes in conjunction with the car door on each floor of the building to allow passengers to get on and off the floor is installed.

At this time, there is a gap between the platform frame and the platform door so that the platform door can be opened and closed smoothly. There was a problem in that if you could not take your hand off the platform door without recognizing that it was opened, the hand could be caught in the gap between the platform door and the platform frame, resulting in injury.

In particular, in the case of a child, there was a lot of concern about a safety accident in which the hand was caught between the platform frame and the platform door because of lack of attention.

In order to solve this problem, Public Utility Model No. 20-2010-0010939 has been proposed.

This relates to a hand jamming prevention device of an elevator, and a car door and a landing door are installed in a fixing part consisting of an upper frame, a left frame, and a right frame to prevent a passenger's hand or foreign substances from being caught in the platform car door. An upper frame left sensor and an upper frame right sensor comprising an object reflective sensor emitting detection light vertically downwards on the inner wall surfaces of both ends of the upper frame corresponding to the outer surfaces of the landing door and the car door is installed in pairs, and on the inner wall surface of the center of the upper frame corresponding to the outer surfaces of the platform door and the car door, a pair of upper frame central sensors comprising an object-reflecting sensor that emits detection light vertically downward is installed and configured, it is possible to prevent the passenger's hand or various foreign substances from being caught during the opening/closing operation of the platform car door.

However, the open utility model has a structure that detects a hand or a foreign substance through detection of a detection light. For example, even when a box or bag that does not affect the opening and closing of the door approaches the door, it detects this and arbitrarily controls the opening and closing of the door. Therefore, it is not only inconvenient for passengers as the forced door opening/closing control is frequently performed in a specific situation, but also has a structurally complicated problem because a number of sensors must be installed in the upper frame and the like.

Also, as another method, Patent Registration No. 10-1238068 has been proposed.

This relates to a safety device for preventing hand jamming of a platform car door, which is located between the elevator car and the car frame provided in the platform and the platform car door opened and closed according to the driving of the door driving motor controlled by the control means. A conductive waveguide sheet for a door that is provided on the surface to sense the current of the human body, a control means for determining whether the current is a microcurrent of the human body when the current is sensed through the conductive waveguide sheet for the door, and one edge of the conductive waveguide sheet for the door It is characterized in that it is composed of a first LED that is installed in the control means to illuminate the light to the conductive waveguide sheet for the door to be turned on under the control of the control means.

According to this configuration, when the electric current of the human body is sensed by touching the edge of the frame of the elevator door or platform, etc., the platform car door is forcibly controlled to prevent injury from getting caught between the platform car door and the frame, and at the same time, the conductive waveguide By irradiating light with the sheet, it can also give the user a sense of visual alertness.

However, in the above-mentioned Registered Patent No. 10-1238068, light can be irradiated to the door surface by installing a conductive waveguide sheet on the surface of the door. The light of the LED installed on one side of the side of the door did not reach the other side enough, so the amount of light irradiated to the door surface was low, so there was a problem of low visibility due to low illuminance.

The configurations for preventing elevator jamming disclosed in the numerous patent documents reviewed above are relatively complex, and since they are installed in a relatively large elevator, the elevator installation cost is increased, which is not economical. There were problems that could cause interference.

In particular, the elevator jamming prevention devices applied to the known technology detect that a finger is caught between the elevator and the wall using a sensor. Since a separate configuration such as a converter is provided, not only the installation cost increases, but also there is a problem that the maintenance cost is high when each configuration fails because there are relatively many configurations.

The jamming detection unit 100 may be divided into left and right when viewed from the front along the vertical longitudinal direction.

That is, when the jamming detection unit 100 is viewed from the front, it may be divided into left and right, and a shape in which straight divided regions formed to be long are vertically formed side by side to be in contact with each other.

A current sensing unit 110 or a laser sensing unit 120 made of a flexible material may be provided on one side facing the platform door 14 from the jamming sensing unit 100, and a rigid support unit 130 may be provided on the other side. can

The support part 130 is formed vertically on the other side of the jamming detection part 100 and is made of a rigid material, so that the safety device of the present invention has the support part 130 serving as a pillar in the longitudinal direction of the platform frame 13 . It can be characterized in that it can be firmly supported and maintained in its shape as it is erected and attached.

Accordingly, the support 130 may be made of a metal material that is strong and has good corrosion resistance and light properties such as aluminum, and any kind of material may be used as long as it is suitable for its purpose.

The support part 130 may be provided with an adhesive member 131 such as a sticker or an adhesive along the back surface of the support part 130 when viewed from one side in contact with the platform frame 13, that is, from the front.

The support 130 may be attached to and fixed to the platform frame 13 by the adhesive member 131, and thus the entire stabilizer of the present invention is stably and firmly attached to the platform frame 13 to maintain its shape. have.

A current sensing unit 110 or a laser sensing unit 120 having a function of directly detecting body jamming may be provided on one side of the jamming sensing unit 100 toward the platform door 14 .

The jamming detection unit 100 may be configured to be arranged side by side on the support unit 130 , and should be configured to be in close contact with the platform door 14 as much as possible.

The gap between the platform frame 13 and the platform door 14 can be minimized when the jamming detection unit 100 is in close contact with the platform door 14 as much as possible in a range that does not interfere with the operation of the platform door 14 .

In addition, when the jamming detection unit 100 is in close contact with the platform door 14 as much as possible, even if a body is caught in the gap, the jamming detection unit 100 can be immediately recognized with high sensitivity, and an immediate response can be made when a safety accident occurs. .

Therefore, the jamming detection unit 100 should be able to detect the jamming of the body sensitively as described above, and at the same time, it should be configured so that the device configured to detect the jamming can be well protected without damage or failure.

For this purpose, the jamming detection unit 100 may be configured as a device for recognizing body jamming in various embodiments, and the present invention is a current sensing unit 110 configured to recognize by a method by sensing current flow, or a laser transmission/reception block. It may be composed of a laser sensing unit 120 configured to recognize by the method.

Therefore, the elevator jamming prevention safety device 10 using the motion sensor of the present invention is the first embodiment in which the jamming detecting unit 100 is composed of the supporting unit 130 and the current sensing unit 110 and the supporting unit 130 and laser sensing. It may be configured in the second embodiment consisting of the unit 120 .

Among the two configurations of the jamming detection unit 100 , the current sensing unit 110 will be described as a first embodiment.

The current sensing unit 110 may include a conductive space 112 , a sensing outer skin 111 , a first conductor 113 , a second conductor 114 , and a protrusion 115 .

The conductive space 112 may be defined as a space formed in the longitudinal direction inside the current sensing unit 110 .

The sensing outer skin 111 forms an outer surface of the current sensing unit 110 , surrounds the conductive space 112 , and may function to protect the conductive space 112 .

The sensing outer skin 111 refers to a portion that directly touches the body when the body is caught between the platform frame 13 and the landing door 14 .

Therefore, the sensing outer skin 111 to be positioned between the platform door 14 of a rigid material and the platform frame 13 holds the body between the platform door 14 and the platform frame 13 when a part of the body such as a finger is pinched. It is preferable to be composed of a soft and ductile material to protect it.

That is, when a body is caught in the gap between the sensing outer skin 111 and the landing door 14, the sensing outer skin 111 must undergo a deformation that pushes in while accommodating the pressure caused by the body's being caught in order to minimize injuries such as body damage. can

And after the body is removed between the jamming detection unit 100 and the platform door 14, the sensing outer skin 111 must be immediately restored to its present shape to fill the gap between the platform door 14 and the jamming detection unit 100 as much as possible and to restore the original shape. It becomes possible to perform the jamming detection function of

Therefore, it is preferable that the sensing outer skin 111 is made of a material having excellent ductility and elasticity with a soft touch, so that deformation due to body jamming and restoration to the present state can be smoothly performed after releasing the pinching.

The sensing outer skin 111 may be made of a material such as silicone or synthetic rubber as an embodiment of the present invention.

The first conductor 113 and the second conductor 114 have electrodes and are high-conductivity conductors provided to conduct electricity when they are in contact with each other so as to face each other at positions opposite to each other in the conductive space 112 . and may be configured with mutually opposite polarities.

The first conductor 113 may be provided on one side in the direction of the outer surface of the sensing outer skin 111 along the longitudinal direction of the conductive space 112 , and the second conductor 114 is the platform frame 13 . It may be provided on the other side in the direction toward.

That is, the first conductor 113 and the second conductor 114 may be respectively provided on the front and rear surfaces when the jamming detection unit 100 is viewed from the front, and it does not matter which conductor is located on the front and rear surfaces, but It should be able to be provided in opposing positions to be opposed.

On the other hand, the first conductor 113 and the second conductor 114 may be respectively provided on both sides when the jamming detection unit 100 is viewed from the front. do.

However, when the body is caught in the gap of the platform 11, the first conductor 113 and the second conductor 114 must be able to contact each other as an external force is applied to the jamming detection unit 100 by the body. In general, when the first conductor 113 and the second conductor 114 are provided on the front and rear surfaces, the probability that they coincide with the direction in which the external force is applied increases, so that a more preferable configuration may be obtained.

The first conductor 113 and the second conductor 114 may be configured as mutually opposite electrodes, so that when a contact is made, a current flows and conducts.

For example, the first conductor 113 may be composed of an anode and the second conductor 114 may be composed of a cathode. Normally, the conductors face each other while being spaced apart by a predetermined distance with the central space of the conducting space 112 interposed therebetween. It can be positioned in the shape of

The protrusion 115 may be configured along the vertical direction on both sides of the conductive space 112 when viewed from the front.

The protrusion 115 may be configured to protrude a predetermined length in the shape of a tetrahedron toward the inner space from the center of each of both side surfaces between the first conductor 113 and the second conductor 114 .

As a result, predetermined portions of both ends of the first conductor 113 and the second conductor 114 are blocked by the protrusion 115 so that they cannot come into contact with each other, and the central portions of the first conductor 113 and the second conductor 114 are closed. It can be a structure that can be in contact with each other.

The protrusion 115 is formed to protrude between the first conductor 113 and the second conductor 114 in the longitudinal direction of the first conductor 113 and the second conductor 114, and the shape has a longitudinal cross-section. It may be a tetrahedron, which is a triangular shape, or may be configured in various shapes such as a hemispherical shape and a cylindrical shape.

The current sensing unit 110 may recognize the pinching of the body as a method of conducting current according to the configuration described above, and the principle is as follows.

Here, as an embodiment of the present invention, it is assumed that the first conductor 113 is disposed as an anode on the surface of the pinch detection unit 100 and the second conductor 114 is disposed as a cathode on the rear surface.

First, when a body jam occurs in the gap between the jamming detection unit 100 and the platform door 14, the corresponding body part applies an external force to the sensing outer skin 111, and the sensing outer skin 111 is made of a material with high ductility and elasticity. Since it is constructed, the surface is deformed according to the direction in which the external force is applied, that is, the direction in which the body is pressed.

When the sensing outer skin 111 is deformed by being pressed, a similar deformation is accompanied therein, and the first conductor 113 is bent into the conductive space in the same manner as the deformation of the sensing outer skin 111 .

Accordingly, the first conductor 113 serving as the positive electrode comes into contact with the second conductor 114 serving as the negative electrode, thereby allowing current to pass therethrough.

The current formed by being energized by the contact between the first conductor 113 and the second conductor 114 can be transmitted to the elevator 20 control unit through the communication module provided in the upper fixing unit 300 as a body jamming detection signal. In addition, the control unit may immediately stop the operation of the landing door 14 and restore it to its original state or maintain the stopped state.

After that, when the body caught in the gap is removed, the current sensing unit 110 is restored to its original shape, so that it can be prepared to prevent another accident.

At this time, the protrusion 115 is provided to serve as a buffer between the first conductor 113 and the second conductor 114 , and the first conductor 113 deformed by an external force is the sensing outer skin 111 . It can function to make it easier to restore when returning to the original state according to the restoration by the elasticity of the .

In addition, the protrusion 115 is limited to a predetermined length and protrudes, so that when the first conductor 113 or the second conductor 114 is deformed, the protrusion 115 can be easily made to contact each other so as not to interfere with the conduction. .

Accordingly, a brief look at the manufacturing process of the current sensing unit 110 configured as described above is as follows.

The current sensing unit 110 is bisected based on the conductive space 112, and a cutout 116 may be formed along the protrusion direction of the protrusion 115 configured on one side of both ends, and the cutout 116 may be the reference. Thus, the current sensing unit 110 may be spread to both sides.

For example, if a cutout 116 is formed on the left side protrusion 115, the left side is bisected along the cutout 116, and the right side has no cutout 116, so it becomes a continuous form, and the right side is connected to the unfolded current sensing unit ( 110) may be provided.

Accordingly, the cutout 116 is cut and the right side surfaces are connected to each other and fixed by inserting each conductor into the inner surface of the conductive space 112 in an unfolded state.

For example, a first conductor 113 is attached to one side of the conductive space 112 to be fixed, and a second conductor 114 is attached to the other side to be fixed.

Thereafter, when the cut ends are joined so as to abut each other so that the protrusion 115 is formed while contacting the cutout 116, the first conductor ( 113) and the second conductor 114 may be attached along the longitudinal direction.

Next, the laser sensing unit 120 will be described as a second embodiment of the two configurations of the jamming sensing unit 100 .

The laser sensing unit 120 may include a light sensing space 122 , a sensing outer skin 121 , a light emitting unit 123 , and a light receiving unit 124 .

The laser sensing unit 120 divides the jamming sensing unit 100 in the longitudinal direction as described above and may be configured side by side with the support unit 130 , and the shape and function of the laser sensing unit 120 is the current sensing unit 110 . may be configured in the same manner as in the first embodiment in which is used.

The sensing outer skin 121 may also have the same function, shape, and material in the above-described current sensing unit 110 .

The light sensing space 122 may be formed as an inner space formed along the longitudinal direction of the sensing outer skin 121 , and the shape may be similar to the conductive space 112 .

The light emitting part 123 may be embedded in the upper fixing part 300 toward the light sensing space and may be provided to emit a laser in the lower fixing part 400 direction.

The light receiving unit 124 is installed in the lower fixing unit 400 toward the light sensing space, and may be provided to face the light emitting unit 123 to receive the laser emitted from the light emitting unit 123 .

As a result, the light emitting unit 123 and the light receiving unit 124 are provided at positions opposite to each other between the upper and lower fixing units 300 and 400 so as to transmit and receive lasers through the light sensing space 122 . can

The light emitting part 123 and the light receiving part 124 are respectively fixed to the upper fixing part 300 and the lower fixing part 400 at positions corresponding to each other with the light sensing space 122 interposed therebetween, thereby emitting from the light emitting part 123 . The laser light can reach the light receiving unit 124 located on a straight line.

If the light emitting unit 123 and the light receiving unit 124 are not fixed and installed separately and capped, the installation is not easy because the positions of the light emitting unit 123 and the light receiving unit 124 must be precisely positioned. If the positions of the light emitting unit 123 and the light receiving unit 124 do not coincide with each other, the function of the jamming detection unit 100 may not function as a jamming prevention safety device.

For this reason, the light emitting unit 123 and the light receiving unit 124 are located in a state of being fixed to the upper fixing part 300 and the lower fixing part 400, respectively, and the upper fixing part 300 and the lower fixing part 400 are pinched. When the installation is completed by covering the upper and lower ends of the branch 100, the light emitting unit 123 and the light receiving unit 124 are located at the corresponding points without adjusting the positions, so that there is no defect during product manufacturing and installation is easy. It can have a simple effect.

Like the current sensing unit 110 , when an external force is applied to the sensing outer skin 121 due to body jamming or the like, the laser sensing unit 120 may be deformed such that the inner space of the light sensing space 122 is pushed and crushed.

That is, when a part of the body is caught between the platform door 14 and the sensing outer skin 121, the sensing outer skin 121 is pressed by the external force applied by the body and deformation occurs, and the light sensing space 122 is formed. Similarly, the inner surface of the skin 121 is also deformed in the direction in which both sides of the light sensing space 122 touch.

Then, the laser emitted from the light emitting unit 123 is blocked by the inner surface of the sensing outer skin 121 that is crushed and protruded into the light sensing space 122 so as not to touch the light receiving unit 124 .

In a normal situation, that is, in a situation in which no external force is applied to the jamming detection unit 100 and thus no body jamming is recognized, the light receiving unit 124 should receive the laser without interruption. ), it is possible to recognize the situation of body jamming by not receiving the laser.

As soon as the light receiving unit 124 fails to receive the laser, it can transmit a body jamming detection signal to the elevator 20 control unit through the communication module provided in the lower fixing unit 400, and the control unit immediately controls the operation of the platform door 14. It can be stopped and restored to its original state or maintained in a stopped state.

The two components of the jamming detection unit 100 described above, that is, the current sensing unit 110 as the first embodiment and the laser sensing unit 120 as the second embodiment, by performing the above-described configuration and operation, the safety of the present invention The device detects that a body or an object is caught in the gap between the platform frame 13 and the landing door 14 and can generate a signal so that an immediate safety action is taken.

On the other hand, the upper fixing part 300 is provided on the upper end of the jamming detection unit 100 in the same shape as a cover to perform a function of protecting the jamming detection unit (100).

The lower fixing part 400 is provided in the same shape as a cover at the lower end of the jamming detection unit 100 similarly to the upper fixing part 300 to protect the jamming detection unit 100 .

The upper fixing part 300 and the lower fixing part 400 block the external force that can be applied through the top and the bottom of the pinch detection part 100 at the top and the bottom of the pinch detection part 100 and prevent the inflow of foreign substances. The current sensing unit 110 and the laser sensing unit 120 may be configured in an external shape for a function of protecting them from malfunction or damage.

In addition, a communication module, a control module, and a power module may be built in the upper fixing part 300 and the lower fixing part 400 .

Therefore, the power module functions to supply power necessary for generation of electrodes and laser generation that can detect body jamming in the jamming detection unit 100, and the control module generates a detection signal when detecting body jamming to connect the communication module. It can be performed including a function of transmitting to the elevator 20 control unit through the.

The communication module, the control module and the power module may be configured by being built-in in both fixing parts of the upper fixing part 300 and the lower fixing part 400, or dispersedly embedded in the fixing parts of both ends, or concentrated on one fixed part may be built-in.

The communication module may be connected to a communication network by wireless communication with the elevator 20 control unit, and a wireless communication network may also be established between the upper fixed unit 300 and the lower fixed unit 400 .

However, it is preferable to construct a wireless communication network, but if necessary for an installation environment or to supplement functions, it may be provided as a wired communication network, or may be configured as a communication network in a form in which wired and wireless are mixed.

The power module is preferably provided as a built-in type using a battery, but may also be configured by being connected to a power supply by wire for continuous supply of power.

Meanwhile, the upper fixing part 300 and the lower fixing part 400 may function to fix the safety device of the present invention to the platform frame 13 .

As for the upper fixing part 300 and the lower fixing part 400, the fixing members 310 and 420 are inserted and coupled in the direction of the platform 13 from their respective surfaces, so that the platform frame 13 can be fixed.

The fixing members 310 and 420 may be used with a device capable of solid coupling and fixed maintenance, such as bolts and nails, and are inserted from the surface of the upper fixing part 300 and the lower fixing part 400 and penetrated through the platform frame (13). It can also be fixed by continuing up to, and a through hole is formed in the portion in contact with the rear platform frame 13 of the upper fixing part 300 and the lower fixing part 400 to be coupled to the platform frame 13 and then covered with a cover. It may be configured in a detachable manner.

Alternatively, a shape change in which the fixing members 310 and 420 are inserted after thinning the thickness after the upper fixing part 300 and the lower fixing part 400 are extended in the longitudinal direction to form a step may also be applied.

The types and coupling forms of the fixing members 310 and 420 are not limited in the method as long as they can maintain a high coupling force without impairing the function of the safety device of the present invention.

On the other hand, the elevator jamming prevention safety device 10 using the motion sensor of the present invention is provided with a motion sensor 210 to induce the safe operation of the platform door 14 by detecting the movement of people and objects. have.

To this end, the motion sensing unit 200 may be provided extending from the lower fixing unit 400 .

One end of the motion detecting unit 200 is coupled to the lower fixing unit 400 , and the other end of the motion sensor 210 is provided to face the front of the platform 11 to detect a motion occurring in the platform 11 .

In particular, the motion sensing unit 200 is located in the lower part of the present invention, so it is characterized in that it is provided to detect the motion at a low position. Motion detection can be better captured.

The motion sensing unit 200 and the lower fixing unit 400 may be coupled by a rotating shaft 410 , and the motion sensing unit 200 rotates along the edge of the lower fixing unit 400 with respect to the rotating shaft 410 . You can move it to adjust its position.

For example, if the overall length of the elevator trapping prevention safety device 10 using the motion sensor of the present invention is relatively long to the platform frame 13, and the motion sensing unit 200 touches the floor during installation, the motion sensing unit 200 is placed on the side. It can be rotated and moved so that it does not touch the floor, and it can be maintained in its shape.

For example, when the safety device of the present invention is installed on the left side of the platform 11 and the motion sensing unit 200 touches the floor, the motion sensing unit 200 is rotated to the left so that it does not touch the floor and the platform door 14. It can be used after making it, and on the contrary, when it is installed on the right side of the platform 11, it can be used by rotating the motion detection unit 200 to the right.

In addition, the motion sensing unit 200 is extended to the lower fixing part 400, but configured to protrude with a higher step than the lower fixing part 400, and then coupled to the rotating shaft 410 to rotate the motion sensing unit 200 in the upper direction. may do it

Therefore, the elevator jamming prevention safety device 10 using the motion sensor of the present invention can have the advantage that it can be mounted and used in any case in various forms of the pre-installed platform 11 structure.

The motion sensor 210 provided in the motion detection unit 200 is provided in the direction of sensing toward the platform 11 so as to detect the movement of people and objects located in the platform 11 when the platform door 14 is opened and closed. can be

At the moment when the platform door 14 is closed, it is regarded as after all people board the elevator 20 or all people get off the elevator 20. When any movement is detected in the platform 11, the elevator door 21 It is necessary to control the movement of the elevator door 21 in advance before a jamming accident occurs.

The motion detection unit 200 of the present invention can function as a preventive safety device that detects the possibility of an accident in advance and takes preemptive measures when the platform door 14 is closed as described above.

In addition, since the motion detection unit 200 is coupled to the lower fixing unit 400 and the position can be changed and set, the direction of sensing by the motion sensor 210 after installing the safety device of the present invention can be changed. It is also applied to the case where it has the characteristic that preventive safety measures can be implemented.

In particular, the motion detection unit 200 may function as a safety device for preventing jamming at the moment the platform door 14 is closed, and the jamming detection unit 100 may cause body jamming at the moment the platform door 14 is opened. As soon as it functions as a safety device, it can be utilized as a double safety device that can function both at the moment when the platform 11 is opened and closed.

Based on the above description, an example of use of the elevator jamming prevention safety device 10 using a motion sensor according to a preferred embodiment of the present invention is as follows.

The safety device of the present invention can be easily installed without the need for additional equipment or devices in the elevator platform 11 where the elevator 20 is installed and operated.

First, the safety device of the present invention is attached to the platform frame 13 configured on one wall of the platform 11 .

First, it is assumed that it is attached to the platform frame 13 provided on the left side of the platform 11 .

When the user sees the jamming sensing unit 100 from the front, the support unit 130 is configured on the left side and the current sensing unit 110 or the laser sensing unit 120 is located on the right side to be attached to the platform frame 13. to set

At this time, regardless of the gap between the platform frame 13 and the platform door 14, the current sensing unit 110 or the laser sensing unit 120 is in close contact with the platform door 14 as much as possible to reduce the gap, so that the body or object is placed in the gap. It is preferable not to be pinched, but it should be located within a range that does not interfere with the operation of the platform door 14 and other elevators 20 .

If the gap between the platform frame 13 and the landing door 14 is narrow, the jamming detection unit 100 may be installed with the entire rear surface in contact with the platform frame 13, which is shown in (a) of FIG. .

On the other hand, if the gap between the platform frame 13 and the platform door 14 is wide, the jamming detection unit 100 has only the support unit 130 in contact with the platform frame 13 while the current sensing unit 110 or the laser sensing unit 120. may be installed in an exposed state between the gaps, which is shown in FIG. 2(b).

That is, as shown in FIG. 2, in a state in which the jamming prevention part 100 is positioned so as to be in close contact with the platform door 14 or the elevator door 21 according to the width of the gap, the support part 130 is attached to the adhesive member 131. By attaching it to the platform frame 13 using a

Therefore, in any case depending on the situation of the gap, the user can fix the jamming detection unit 100 to the platform frame 13 using the adhesive member 131 provided on the rear surface of the support unit 130, and a stable fixing state is maintained. By making it possible to maintain, it is possible to expect high utilization and practical effects that can be applied accordingly in any case where the size of the gap is different.

As described above, the elevator jamming prevention safety device 10 using the motion sensor of the present invention has the advantage of being comprehensively applicable regardless of the width of the gap between the platform 11 and the platform door 14 .

Thereafter, the user can further strengthen the installation fixing state by inserting the fixing members 310 and 420 into the upper fixing part 300 and the lower fixing part 400 , respectively, and coupling them to the platform frame 13 .

In the installation process, if the safety device of the present invention is longer than the installable length of the platform frame 13 and the motion sensing unit 200 touches the floor, the motion sensing unit 200 is rotated to the left and installed to be spaced apart from the floor. can

Alternatively, if the user wants to increase the position of the motion sensor 210 of the motion sensing unit 200 according to specific needs, the user installs the safety device of the present invention as high as possible and then rotates the motion sensing unit 200 to the left to increase the height. It can also be rotated to the top or can be configured so that the motion sensor 210 senses at a higher position.

On the other hand, if the safety device of the present invention and the platform door 14 are far away, so that the motion sensor 210 is closer to the platform door 14 and then wants to sense it, the motion detection unit 200 may be installed by rotating it to the right.

As described above, through the rotational movement of the motion sensing unit 200, it is possible to use the platform 11 for general purpose through setting various positions according to the shape of the platform 11 and the intention of the user.

On the other hand, the safety device of the present invention may be installed by attaching it to the right frame of the platform 11.

In this case, as opposed to the above-described left frame installation process, the support unit 130 may be configured on the right side and the current sensing unit 110 or the laser sensing unit 120 may be positioned on the left side.

That is, when installed on the left platform frame 13, the front and rear sides of the installed form may be inverted and used.

In addition, since the direction of the rear surface of the support part 130 is also changed, the adhesive member 131 may be attached to the platform frame 13 by being provided on the rear surface of the support part 130 which is newly set.

The motion sensing unit 200 separates the rotating shaft 410 from the lower fixing unit 400, reverses the front and rear directions, installs the motion sensor 210 to face the platform 11, and then inserts the rotating shaft 410 again. Thus, the motion detection unit 200 may be configured.

Now, the motion detection unit 200 is installed at a desired position by rotating it in the left, right, and upper directions according to the height from the floor, the distance from the platform 11, the purpose of use, etc., as in the case of being installed on the left platform frame 13 . can be

As such, in order to be installed in either direction of the platform frame 13 of the left and right sides, the motion sensing unit 200 and the lower fixing unit 400 of the present invention may have the rotating shaft 410 separated, and the motion sensing unit ( 200) may be configured in a form that can be coupled by the rotation shaft 410 in either direction on the front and rear surfaces of the lower fixing part 400, so the elevator jamming prevention safety device 10 using the motion sensor of the present invention is It has the advantage of versatility that does not have problems such as being manufactured in a separate form or limited in use depending on the environment of use.

Thereafter, the installation can be completed by inserting and combining the fixing members 310 and 420 in the upper fixing part 300 and the lower fixing part 400, and it can be used in the same way and as the same device in any direction of the platform frame 13. .

When the safety device of the present invention is installed on the platform frame 13 through the above procedure, the safety device can be driven when the platform door 14 is opened and closed.

First, after the elevator 20 arrives at the platform 11, at the moment the elevator door 21 and the platform door 14 are opened, if a part of the body, such as a hand, is caught in the gap on the side of the platform door 14, the hand is not detected. The skin 111 and 121 are pressed.

If the jamming detection unit 100 is configured as the current sensing unit 110 as the first embodiment of the present invention, the sensing outer skin 111 pressed by the hand is deformed and the first conductor 113 is formed in the conductive space ( 112) It is squashed and pushed into the center, and contact is made with the second conductor 114 on the opposite side.

When the first conductor 113 and the second conductor 114 come into contact and energized, the control module immediately generates a jamming detection signal and transmits it to the elevator 20 control unit through the communication module to the elevator 20 and the elevator door ( 14) can be stopped.

If the pinch detection unit 100 is configured with the laser detection unit 120 as the second embodiment of the present invention, the sensing outer skin 121 pressed at the moment of the hand pinch is deformed and the light sensing space 122 formed therein. ), and the laser emitted from the light emitting unit 123 is blocked, so that the light receiving unit 124 cannot receive the laser.

As soon as the laser is cut off in the light receiving unit 124 , the control module generates a jamming detection signal and transmits it to the elevator 20 control unit through the communication module to stop the operation of the elevator 20 and the elevator door 14 .

On the other hand, at the moment when the elevator door 21 and the platform door 14 are closed after a person in the elevator 20 gets off and boarding is completed, there is no person at the opening or closing point of the door of the platform 11 in front of the platform door 14 There should be no movement for getting off.

However, when the platform door 14 is closed, the motion sensor 210 detects the movement of a person or an object at the opening and closing point of the platform 11 door, immediately the control unit generates a motion detection signal and transmits it to the elevator 20 control unit. The elevator door 21 and the landing door 14 can be controlled to stop closing and reopen, and to suspend the operation of the elevator 20 until it is determined whether it is normal.

Meanwhile, the elevator jamming prevention safety device 10 using the motion sensor of the present invention may be installed in the elevator 20 .

As the elevator door 21 opens and closes in the elevator 20, a gap of a predetermined width is formed in the entrance and exit parts on both sides of the front side of the elevator 20. The safety device of the present invention is attached to the interior wall of the elevator 20. It may be installed adjacent to the elevator door 21 .

Therefore, when the elevator door 21 is opened and closed inside the elevator 20, when a part of the body such as a finger is caught between the elevator door 21 and the inner wall of the elevator 20, it is immediately recognized and the operation can be stopped. have.

On the other hand, an elevator communication unit (not shown) may be mounted on the upper part of the elevator, and the elevator communication unit is provided to interoperate with the communication module built in the safety device of the present invention installed in the platform 11 on each floor of the building to achieve economic efficiency. can be promoted

That is, when the elevator 20 is moving and stops at a specific floor for a stop, the elevator communication unit transmits a signal to the communication module of the present invention installed in the platform frame 13 indicating that the elevator 20 is stopping and moving on the corresponding floor. Accordingly, the jamming detection unit 100 of the present invention may be in an operation standby state, and at the same time receiving a signal from the elevator communication unit from the communication module, the control module may activate the jamming detection unit 100 .

Therefore, the elevator jamming prevention safety device 10 using the motion sensor of the present invention installed in the platform 11 of each floor can not wait while consuming energy sources in a normal operation state regardless of the operation of the elevator 20, (20) can be started immediately during operation and can function as a jam-preventing safety device, thereby preventing economic loss and performing the best safety device function.

The safety device of the present invention attached to the inner wall of the elevator 20 can be made in the same configuration and method as when it is attached to the platform frame 13, and the safety device can be provided simply without additional equipment or additional devices.
