Description

[Technical Field]

[0001] The present invention relates to the operation of electronic or electric locks. [Background technology]

[0002] Electronic or electric locks installed on front doors are designed to automatically lock when the door is closed, but since the lock remains on even in emergencies such as fires, it is necessary to unlock the door in the event of an emergency evacuation or rescue.

Alternatively, by linking the signal from the electronic lock or electric lock of the present invention to the sound made by an installed fire alarm in the event of a fire, the electronic lock that has been locked by the sound made by the fire alarm that detects a fire can be unlocked. [Effects of the Invention]

[0006] By installing the electronic lock of the present invention, it is possible to respond to fire emergencies without requiring major construction work on the door.

[0007] By installing the electric lock of the present invention, it is possible to respond to fire emergencies without requiring major construction work on the door. [Brief explanation of the drawings]

[0009] In this description, an electronic lock that is powered by a battery is defined as an electronic lock and is referred to as an electronic lock.

[0010] In this explanation, electronic locks refer to both those that require holes or screws to be drilled into the door and cannot be easily removed or relocated, and those that do not require holes or screws to be drilled into the door and can be easily removed or relocated, as shown in the structural explanation below.

[0011] In this description, an electric lock that is powered by a commercial power source is defined as an electric lock and will be referred to as an electric lock. DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings, but the technical scope of the present invention is not limited to this embodiment.

[0013] 1 to 6 show examples of installation of an electronic lock device according to an embodiment of the present invention. The electronic lock device depicted here can be installed without drilling holes or screwing into the door. Specifically, FIG. 1 is an overall external view of the present invention. FIG. 2 shows an example of an installation position of an electronic lock of the present invention as seen from the interior side of the front door. FIG. 3 is an enlarged view of the installation position of an electronic lock of the present invention. FIG. 4 is a cross-section illustrating the installation position of an electronic lock of the present invention on a front door, and FIG. 5 is an enlarged view illustrating hemming of a thin steel plate used in an example of an installation form. FIG. 6 is a perspective view of the front door as seen from the outside, showing how a portion of the present invention looks from the outside.

[0014] Furthermore, Figs. 7 to 11 are explanatory diagrams of the mechanical configuration and operation of an example embodiment of the present invention. Specifically, Fig. 7 is a front view of the electronic lock of the present invention when locked with the top cover (no reference numeral) removed, and Fig. 8 is a front view of the electronic lock when unlocked. Fig. 9 is a perspective view of the configuration of the electronic lock of the present invention when the top cover and bottom case (no reference numeral) are removed. Furthermore, Fig. 10 is a perspective view of the frame configuration of the mechanical components in the electronic lock of the present invention to be installed on a front door.

[0015] The following description will be given in order, starting with Figure 1. Figure 1 shows the external appearance of an electronic lock body 100, which is made up of a deadbolt 120 and a retaining plate 110.

[0016] Next, an example of the installation position of the electronic lock main body 100 in Fig. 1 will be explained with reference to Fig. 2. The electronic lock main body 100 is installed at the upper end of the front door 10 on the side of the lever handle a 11. Fig. 2 also serves to explain the cross-sectional position of Fig. 4 (described later).

[0017] The deadbolt 120 in FIG. 3 is positioned so as to overlap with the entrance door frame protrusion 20a, and details will be explained in FIG.

[0018] In Figure 4, a retaining plate 110 is fixed to the entrance door 10 with double-sided tape 114, and the retaining plate 110 also holds down the outside of the entrance door 10. The reason the retaining plate 110 is made of a thin steel plate is because it is installed in the gap between the entrance door 10 and the entrance door frame protrusion 20a. The shape of the tip of the retaining plate 110 that holds down the entrance door 10 from the outside is explained in detail in Figure 5.

[0019] In Fig. 5, the tip of the holding plate 110 is shaped as a hemming bent portion 110a, and the electronic lock body 100 in Fig. 4 is fixed in the gap between the hemming bent portion 110a and the front door 10 via a cushion 113. When a strong force is applied outward in the pulling direction from the handle lever 13 b in Fig. 6, the hemming bent portion 110a is directly received by the front door 10.

[0020] Figure 6 shows how the electronic lock looks on the upper outside of the front door 10, and is designed to be unobtrusive aesthetically. The front door 10 and the front door frame 20 are connected via hinges a 15, b, and c.

[0021] Figure 7 shows the locked state of the electronic lock body 100 in terms of the position of the deadbolt 120, and Figure 8 shows the unlocked state of the electronic lock body 100 in terms of the position of the deadbolt 120 in a tilted position, i.e., away from the front door frame protrusion 20a. Here, the deadbolt 120 rotates around a shaft 121.

[0022] Next, the configuration of the electronic lock main body 100 will be explained using Figures 9 and 10. The explanations of Figures 9 and 10 here are for a state where the lower case 101 and upper cover 102 (both without reference numerals) are removed. In Figure 10, a holding plate 110, which is a thin steel plate, and a frame 111, which is made of a steel plate thicker than the holding plate 110, are joined by welding or the like to improve strength. In Figure 9, a base plate assembly 130 is mounted on the frame 111. In addition, a battery case 115 is fixed to the frame 111 together with a battery 116.

[0023] The electronic lock or electric lock of the present invention communicates with the fire alarm via wired or wireless means such as Bluetooth or Wi-Fi. The communication means is not particularly specified.

[0024] When a fire alarm sounds in the event of a fire, the electronic lock or electric lock of the present invention performs an unlocking operation in response to a communication signal from the fire alarm.

[0025] The electronic or electric lock of the present invention is configured to recognize and respond to the sound of a fire alarm when a fire occurs.

[0026] When a fire alarm sounds in the event of a fire, the electronic or electric lock of the present invention performs an unlocking operation in response to the sound from the fire alarm.

[0027] The electronic lock or electric lock according to the present invention has either of the following functions: an unlocking method using wired or wireless communication with a fire alarm, or an unlocking method using the sound of the fire alarm.

[0028] By unlocking the door in the event of a fire, doors that would not open without a special unlocking operation are automatically unlocked, making evacuation and rescue easier in the event of a fire. [Explanation of symbols]
