Description

Technology Field

[0001] The present invention relates to a safety indicator device for passing through elevator doors, and more specifically, to a safety indicator device for passing through elevator doors in which a guide means is installed on the car door seal of an elevator car to distinguish and indicate, through different colors, whether the car door of the elevator car and the landing door of the passenger are open or closed, open is complete, or just before closing from fully open, thereby inducing safer and more orderly boarding and alighting of the elevator and at the same time establishing such a boarding and alighting culture. Background Technology

[0003] Generally, an elevator is a vertical transport device that uses power and is installed in buildings or fixed facilities to transport people or cargo to a landing along a set path.

[0004] Elevators play a role in enabling users to move between floors in a building more quickly and conveniently. For the operation of such elevators, a vertical shaft is formed inside the building for the elevator car to ascend and descend, and a landing connected to the shaft is provided on each floor of the building, with a door installed between the shaft and the landing. Users operate a call button installed on the wall of the building, positioned to the left or right of the landing door, to move the elevator car to the landing of the corresponding floor and use it.

[0005] Most people use these elevators because they allow for quick and convenient movement between floors. In particular, the number of elevator users increases rapidly during commuting or school hours in office buildings and apartments, and this is even more true for large shopping malls and department stores. There is a need for technology to assist passengers and those waiting to board the elevator safely, not only during normal times but also during peak hours when usage surges.

[0006] Furthermore, for people with disabilities who have difficulty getting on and off elevators quickly, such as the elderly, the disabled, and the visually impaired, elevator car doors and landing doors are designed to stop for at least 10 seconds after being fully open before closing. However, since most buildings do not apply this as is, there is a need for technology that can make the process of getting on and off elevators safer for people using them. Prior art literature

[0020] Hereinafter, the safety indicator device for elevator door passage according to the present invention will be described in more detail with reference to the attached drawings.

[0021] Prior to this, terms and words used in this specification and claims should not be interpreted as being limited to their ordinary or dictionary meanings, but should be interpreted in a meaning and concept consistent with the technical spirit of the invention, based on the principle that the inventor can appropriately define the concept of the terms to best describe his invention.

[0022] Therefore, the embodiments described in this specification and the configurations illustrated in the drawings are merely the most preferred embodiments of the present invention and do not represent all of the technical ideas of the present invention; thus, it should be understood that various equivalents and modifications that can replace them may exist at the time of filing this application.

[0024] “A” of FIG. 1 is a schematic plan view illustrating an entry guidance means, which is a safety indicator device for passing through an elevator door according to a preferred embodiment of the present invention, and “B” is a schematic plan view showing the car door and elevator door in an open state; FIG. 2 is a cross-sectional view along line a-a' showing the installation structure of an LED bar according to a preferred embodiment of the present invention, and FIG. 3 is a block diagram showing the configuration of the entry guidance means according to a preferred embodiment of the present invention.

[0025] First, referring to FIGS. 1 to 3, the safety indicator device for elevator door passage according to the present invention is configured to include an entry / exit guidance means (100).

[0027] Before examining this, as widely known, a vertical passage is formed in the building for the vertical movement of an elevator car (10), and a landing (20) for the boarding and alighting of passengers is provided on each floor of the building. An elevator car (10) is installed in the vertical passage of the building, and a car door (14) is provided on the elevator car (10) side and a landing door (24) is provided on the landing (20) side. When the elevator car (10) stops at the landing (20), the two doors (14, 24) open simultaneously, and passengers board and alight, which is natural, and a door detection sensor (30) is provided to detect whether the door is open or closed.

[0028] Additionally, a car door seal (12) with a rail groove formed therein is provided on the lower front side of the elevator car (10) to guide the opening and closing of the car door (14), and a landing door seal (22) is provided on the landing side (20) to guide the opening and closing of the landing door (24). In other words, the two door seals (12, 22) are provided in a spaced-apart space between the elevator car (10) and the landing (20) to guide the opening and closing operation of the doors (14, 24). As shown in “B” of FIG. 1, after the two doors (14, 24) are opened and closed, the door seals (12, 22) guiding each door are clearly visible. These door seals (12, 22) are installed to guide the opening and closing of the doors (14, 24) while also preventing passengers from slipping into the space between the elevator car (10) and the landing (20). It is obvious that as the elevator car (10) moves up and down, the two door seals (12, 22) maintain a minimum gap. Since this configuration is widely known, a separate detailed description is omitted in this invention.

[0030] Meanwhile, the entry / exit guidance means (100) of the present invention comprises an LED bar (110), a boarding warning unit (120), and a control unit (130).

[0031] First, as shown in FIG. 2, the LED bar (110) is installed in the direction of opening and closing of the car door (14) on the car door seal (12) which is provided on the lower front side of the elevator car (10) and guides the opening and closing operation of the car door (14), and emits light in one of the colors red, green, and yellow by means of a control signal. Meanwhile, when the LED bar (110) is installed on the side of the car door seal (12) and emits light, the light is softly emitted through the spaced-apart space between the landing door seal (22) and the car door seal (12), as previously described, so it will be visually advantageous. In addition, when the car door (14) is closed, there is an advantage that the LED bar (110) inside the elevator car (10) cannot be seen with the naked eye. Although the LED bar (110) is installed for safety of passage, if it is exposed to the outside when unnecessary, it may be inconvenient for users, and if it malfunctions and lights up during operation, passengers may be startled.

[0032] Meanwhile, if the LED bar (110) is embedded in a separate space, such as the floor of the elevator car (10), there will be significant inconvenience in terms of maintenance, such as replacing the LED bar (110) from the initial installation. However, in the present invention, by mounting the LED bar (110) on the car door seal (12), there are significant advantages in terms of maintenance, such as replacement, and there is also the advantage of minimizing inconvenience to users as it does not protrude outward in appearance.

[0033] At this time, as shown in the enlarged view, when installing the LED bar (110), the upper side may be covered with a transparent cap (112) to prevent the LED bar (110) from being directly exposed to foreign substances or rainwater.

[0035] Next, the boarding warning unit (120) is installed on one side of the interior of the elevator car (10) and is in the form of a speaker that outputs voice guidance messages in response to a control signal.

[0037] Next, the control unit (130) receives a signal from a door detection sensor (30) that detects the opening and closing of the car door (14) as shown in FIG. 3, and controls the LED bar (110) and the boarding warning unit (120). When the car door (14) begins to open, it outputs a corresponding control signal to light up the LED bar (110) in red and simultaneously broadcasts a warning message through the boarding warning unit (120) to be careful because the door is opening. When the car door (14) is fully opened, it outputs a control signal to light up the LED bar (110) in green. When the car door (14) is fully open, it controls the LED bar (110) to flash yellow 2 to 3 seconds before the door closes and simultaneously broadcasts a warning message through the boarding warning unit (120) to be careful because the door is closing soon. When the door (14) begins to close, the LED bar (110) is turned red through control and at the same time, a warning message that the door is closing is broadcast through the boarding warning unit (120), and when the car door (14) is completely closed, the LED bar (110) is turned off through control.

[0039] When configured in this way, the control unit (130), which is the entry / exit guidance means (100) of the present invention, outputs a corresponding control signal when the car door (14) begins to open, thereby illuminating the LED bar (110) in red, and the boarding warning unit simultaneously broadcasts a voice guidance message saying, “The elevator door is opening.”

[0040] When the car door (14) is fully opened, a control signal is output to light up the LED bar (110) in green, and additionally, a voice guidance message saying “The door is fully open, please be careful when getting on and off” may be broadcast through the boarding warning unit (120).

[0041] Continuing, when 10 seconds have passed with the car door (14) fully open, the corresponding control signal is output to flash the LED bar (110) yellow for 2 to 3 seconds, and the boarding warning unit (120) simultaneously broadcasts a voice guidance message saying, “The elevator door is closing.”

[0042] When the car door (14) begins to close, the corresponding control signal is output to light up the LED bar (110) in red, and the boarding warning unit (120) broadcasts a voice guidance message saying “The door is closing.”

[0043] When the car door (14) is completely closed, the corresponding control signal is output to turn off the LED bar (110) and switch to a standby state.

[0045] It is obvious that the operating relationship mentioned above, namely the flashing signal or lighting color of the LED bar (110) and the voice message of the boarding warning unit (120), may be displayed or expressed differently depending on the situation.

[0047] According to the above configuration, when the car door (14) of the elevator car (10) and the landing door (24) of the landing (20) are in the opening or closing operation, a red strip-shaped mark indicating the prevention of boarding and disembarking is displayed on the floor surface adjacent to the car door (20) of the elevator car (10), and at the same time, a voice message guiding the prevention of boarding and disembarking is transmitted. By visually and audibly perceiving this, waiting passengers and passengers can take precautions when boarding or disembarking, thereby effectively preventing collisions and getting stuck between the doors during the opening and closing operation of the car door (14) and the landing door (24). This significantly reduces the risk of safety accidents for passengers and also reduces elevator door malfunctions, thus providing advantageous effects in terms of safety and maintenance.

[0049] The foregoing is merely a preferred embodiment formed by a slight improvement of the present invention and is by no means intended to limit the present invention; any equivalent variation or equivalent change made to the improvement of the present invention, or any combination not illustrated in this specification, should be included within the scope of protection of the present invention.
