Description

Safe deposit box with display panel

Technical Field

The present invention relates to a safe having a display panel, and more particularly, to a safe having a display panel, which allows an article in a main body to be checked from the outside as the amount of light passing through an internal light source increases.

Background

Generally, a hinge is a device attached to a body and a door to enable opening and closing of the door. The hinge is a device that can be engaged with and rotated about two symmetrical metal plate column shafts, and has a function as a hinge as one of the garnish and the opening/closing member. They are classified into an exposed hinge and a hidden hinge according to the attached appearance, and into a long hinge and a short hinge according to the size. For its purpose, a door is attached to a body to be able to open and close the door, and therefore is an essential device for a side hung door.

On the other hand, in schools, laboratories, hospitals, and the like, there are doors that do not transmit light, such as drugs, volatile substances, explosive substances, and chemical substances that react to sunlight and light such as indoor lighting, in order to block light. Therefore, there is no method to confirm the internal state other than the method of confirming the inside by opening the door, or the internal state cannot be known without a special device.

In particular, even if a chemical leakage, a toxic gas formation, or a fire occurs inside the storage box, it is not immediately known, which increases the risk, and in such a case, when the door is opened, the door must be opened without confirming the internal state, which causes a problem of being very dangerous to the user.

One example of a technique for solving these problems is disclosed in the following patent documents 1 to 3 and the like.

For example, patent document 1 (korean patent laid-open publication No. 10-1632300, 2016, 06, 15) discloses a functional perspective door for furniture, which is a functional perspective door for furniture provided at an entrance of a furniture F, as shown in fig. 1, and includes: door frames 11 to 14 each having a quadrangular frame shape; a base plate 21 provided inside the door frame; an LED module 20 including an LED chip 22 and a lens 23; a front transparent member 30 fixed to the front side of the door frame; a first reflective layer 35 which is positioned on the front transparent member 30 and reflects light; a rear transparent member 40 fixed to a rear side of the door frame; a second reflective layer 45 that is located on the rear transparent member 40 and reflects light; a cover body having a cross section opened upward

A shape; and a module cover formed on an inner surface of the cover body on an inlet side and having an insertion groove 62 into which the PCB substrate 21 of the LED module is inserted.

Further, patent document 2 (korean patent laid-open publication No. 10-1975757, granted on 30/04/2019) discloses a state sensing see-through safe deposit box which informs of an internal specific state of a safe deposit box main body, and includes: a safe box main body for receiving an object; a sensor that senses a specific state inside the safe deposit box; a door (door) provided in the safe box main body and having a transmission window; a light emitting module that increases an amount of light emitted according to a signal from a sensor that senses a specific state inside the safe deposit box to increase an amount of light reflected inside the safe deposit box toward the transmission window; and an optical film provided on the transmission window.

On the other hand, patent document 3 (korean patent laid-open publication No. 10-1376705, granted No. 03/14/2014) discloses a furniture hinge including a light control device that is engaged with an outer surface of a furniture engaging portion of a hinge portion and is controlled by being brought into contact with a door fixing portion when a door is opened, the light control device including: a light adjusting body which is matched with the furniture matching part and is installed not to be separated along the up and down direction; an LED lamp unit formed obliquely on a rear side of the light control body and provided to be capable of irradiating the inside of the furniture; a lighting switch unit which is provided so as to protrude forward of the dimming body, contacts a door fixing unit to disconnect the LED lamp unit, and lights the LED lamp unit when the door fixing unit is detached; and a power supply unit provided inside the door fixing unit.

Fig. 12 is a perspective view illustrating a configuration of the power supply part illustrated in fig. 9, and fig. 13 is a perspective view illustrating a configuration of the first power supply part illustrated in fig. 12.

As shown in fig. 9 and 12, the power supply unit 170 includes a first power supply unit 171 coupled to the hinge 110 and a second power supply unit 172 coupled to the frame 120, and electrically connects the first power supply unit 171 and the second power supply unit 172 when the door 100 is closed, and electrically disconnects the first power supply unit 171 and the second power supply unit 172 when the door 100 is opened.

As shown in fig. 11 and 12, the first power supply unit 171 includes: a first protrusion 173 protruding from the first terminal; a first cable 176 electrically connected to the first terminal to receive power supply from the main body; and a pair of fitting portions 178, the first cable 176 being fitted into the connection insertion hole 179.

The first terminal and the first protrusion 173 are electrically insulated from each other, and the pair of engagement portions 178 are fitted into the engagement grooves 114 provided in the body fixing portion 112, whereby the first power supply member 171 is coupled to the hinge 110.

As shown in fig. 12, the second power supply unit 172 includes: a second protrusion 174 protruding from the second terminal; a screw hole 175 provided for fixing to the frame 120 with a screw or the like; and a second cable 177 electrically connected to the first terminal to supply power to the light emitting part 160. The second terminal and the second protrusion 174 are electrically insulated from each other, the first protrusion 173 is in contact with the second terminal, and the second protrusion 174 is in contact with the first terminal, so that power can be supplied to the light emitting member 160. That is, the first terminal is electrically insulated from the first protrusion 173 and electrically connected to the second protrusion 174. The second terminal is also electrically insulated from the second protrusion 174 and electrically connected to the first protrusion 173. The first protrusion 173 and the second protrusion 174 are provided to have functions of, for example, a plus (+) terminal and a minus (-) terminal.

As described above, by providing the first protrusion 173 on the first terminal and the second protrusion 174 on the second terminal, electric shock can be prevented during use, and the electrical connection state can be maintained even if the opening and closing operation of the door 100 is repeated.

Therefore, when the door 100 is opened in the main body, the first protrusion 173 and the second protrusion 174 are spaced apart from each other to cut off the power supply to the light emitting member 160, and when the door 100 is closed in the main body, the first protrusion 173 and the second protrusion 174 are in contact with the second terminal and the first terminal, respectively, and the standby voltage state is maintained by the operation of the switching circuit.

Thereafter, when the user touches or taps the glass member 130, the motion sensing member senses the motion and the motion sensing information thereof is transmitted to the light emitting member 160, so that the switching circuit is in an on state, and thus, when the plurality of LED light sources 162 emit light, external light passes between the plurality of nano-scale air holes formed in the transmittance variable panel 150 as the amount of light between the transmittance variable panel 150 and the protection panel 140 increases, so that the article in the body can be confirmed from the outside. The plurality of LED light sources 162 may be operated for a predetermined time by operating the switching circuit for a timer of a predetermined time.

As described above, according to the present invention, since the plurality of LED light sources 162 emit light for a predetermined time period only by the operation of the activity sensing means and the timer, power consumption can be reduced.

Next, a further embodiment of the present invention will be described based on fig. 14 to 16.

Fig. 14 is a partial front view of another example of the door having the transmittance variable panel illustrated in fig. 8, fig. 15 is a view illustrating a light emitting part of still another example of the transmittance variable panel according to the present invention, and fig. 16 is a view illustrating one example of a movable sensing part mounted on a body having the transmittance variable panel according to the present invention.

In the embodiment illustrated in fig. 10 and 11, the explanation has been made in a configuration in which the substrate 161 is flat and the plurality of LED light sources 162 are directed to the periphery of the transmittance variable panel 150, but the plurality of LED light sources 162 may be disposed to be directed to the inside of the body as indicated by the arrows in fig. 14.

As shown in fig. 15, the substrate 161 may be formed in a trapezoidal shape and the LED light sources 162 may be arranged to face the variable transmittance panel 150. Therefore, the light emitting component 160 can be easily provided by applying the substrate 161 as shown in fig. 15.

In addition, although the above embodiment has been described with the structure in which the movable sensing member is provided on one side of the frame 120, as shown in fig. 16, the present invention can also be applied to a structure in which the movable sensing member 180 is provided on the upper portion of the main body 200 and the light emitting member 160 is operated. That is, the second power supply unit 172 may supply power to the light emitting unit 160 when the motion sensor 180 senses a motion of the user, for example, a palm or the like of the user.

Although the invention made by the present inventors has been specifically described above based on the above embodiments, the present invention is not limited to the above embodiments, and it goes without saying that various modifications are possible within a range not departing from the gist of the present invention.

That is, in the above description, as shown in fig. 10, the variable transmittance panel 150 is attached in parallel with the glass member 130, and the LEDs of the light emitting member 160 face the periphery of the variable transmittance panel 150, but the present invention is not limited thereto, and the variable transmittance panel 150 may be attached to the light emitting member 160 in an inclined manner so that the light emitted from the light emitting member 160 passes through the glass member 130 via the air holes of the plurality of nano-scale.

In the above description, the first terminal has the first protrusion 173 and the second terminal has the second protrusion 174, but the present invention is not limited to this, and the present invention may be applied to a structure in which the first protrusion 173 and the second protrusion 174 are provided on either the first terminal or the second terminal.
