The description of the first embodiment can be equally applied to the other embodiments listed above unless otherwise exceptionally detailed.

Figure 5 is a state diagram of a safety slide key door lock including a key safety guard according to an embodiment of the present invention according to the position of the sliding bar.

Referring to FIG. 5 , a safety slide key door lock 100 including a key safety guard according to an embodiment of the present invention includes a key safety guard 110, a slider 120, and a door switch assembly 130. can be configured to

The slider 120 functions to trigger physical opening/closing of the door 11 and ON/OFF of a driving contact point of a machine or robot. The slider 120 may include a slider groove 121 , a sliding bar 22 , a handle 123 and an actuator 124 .

The door switch assembly 130 may include a base 131 , a receptacle 132 , and a door switch 134 .

The base 131 may be integrally formed with the receptacle 132, and the door switch 134 may be mounted on the base 131.

The receptacle 132 is engaged with the sliding bar 122 in the locked state of the door 11 and is separated from the sliding bar 122 so that the door can be converted into an openable state.

The door switch 133 is combined with the actuator 124 to control the operation contact points of machines, robots, and the like. That is, the door switch 134 switches the contact point from OFF to ON when a change in the recognition of the actuator 124 occurs in a state in which the actuator 124 is not recognized. Conversely, when an unrecognized change in the actuator 124 occurs in a state in which the actuator 124 is recognized, the contact is switched from ON to OFF.

Figure 6 is a state diagram of a safety slide key door lock including a key safety guard according to an embodiment of the present invention according to the position of the sliding bar.

Referring to FIGS. 5 and 6 together, FIG. 5 depicts the safety slide key door lock 100 in an OFF state of the driving contact point before the door 11 is opened. Since the sliding bar 122 is biased to the right, the actuator 124 is separated from the door switch 133. In the state of FIG. 5 , the key 127 is located farthest from the rotation shaft 112 . Therefore, the key 127 is located in the area of the free end 111b of the key safety guard body 111.

6 depicts a state in which the door 11 is in a closed state and the driving contact is in an ON state. Since the sliding bar 122 is biased to the left, the actuator 124 is coupled with the door switch 133. In the state of FIG. 6 , the key 127 is positioned closest to the rotation shaft 112 . Therefore, the key 127 is located in the region of the fixed end 111a of the key safety guard body 111.

When the sliding bar 122 starts to move to the left in the state of FIG. 5, the key safety guard body 111 rotates counterclockwise, and the key 1270 changes its position so that it is positioned close to the rotation shaft 112. will do The radius of curvature of the curved surface formed by the key safety guard body 111 may be determined according to the vertical position difference between the rotating shaft 112 and the key 127 .

The function of a general door lock is to limit the opening of the door in a locked state, but the function of the safety slide key door lock 100 is to limit the closing of the door 11 in an open state. Here, the lock 125 and the key 127 function to switch lock setting/release of the sliding bar 122.

The lock 125 may be configured to restrict the movement of the sliding bar 122 by manipulation of the key 127 so that the door 11 in the open state is restricted from being locked. That is, contrary to the concept of a general door lock, the lock 125 and the key 127 have a function of limiting the closing of the opened door 11 .

The safety slide key door lock 100 is often installed at the entrance of a chamber where a device operating in an unattended state, such as a machine or robot, is disposed, or installed along with a fence surrounding an area. While the unmanned device is operating, the door 11 is closed and the key 127 is coupled to the lock 125, so the safety slide key door lock 100 is in an unlocked state, so the sliding bar 122 is in a movable state. is in

In the event of a problem with the unmanned device and maintenance is required, the operator can switch the operation contact from ON to OFF to stop the operation of the machine before entering the danger zone, with the key (127) inserted into the lock (125). , the sliding bar 122 is moved from the position shown in FIG. 6 to the position shown in FIG. 5 .

7 is a state diagram of a safety slide key door lock including a key safety guard according to an embodiment of the present invention according to the rotation of the key safety guard body.

Referring to FIG. 7, the state 111-2 of the key safety guard body 111 depicted in FIG. 5, the state 111-1 of the key safety guard body 111 depicted in FIG. 6, and the door 11 A state 111-3 of the key safety guard body 111 in an openable state is depicted.

When the actuator 124 is separated from the door switch 133 by the movement of the sliding bar 122, the contact is released and the operation of the machine in operation stops.

Prior to entry into the danger zone, the operator pushes the sliding bar 122 coupled with the receptacle 132 to release the coupling. As the sliding bar 122 is removed from the receptacle 132, the actuator 124 is removed from the door switch 133, the operation contact of the machine is switched from ON to OFF, and the key safety guard body 111 is in the state (111-1) ) to state 111-2.

Next, after converting the key 127 coupled to the lock 125 to the locking position, the operator must separate the key 127 from the lock 125 and carry the separated key 127. The purpose of possession is to prevent the locked state of the lock 125 from being released by another person.

This is because if the lock 125 is unlocked and the sliding bar 122 is moved, the contact point is switched from OFF to ON and the machine is operated, resulting in a safety accident.

However, there is a problem that safety accidents frequently occur in the safety slide key door lock 100 according to the prior art. A worker entering a dangerous area for maintenance forgets to possess the key 127 . When the key 127 is coupled to the lock 125, the key safety guard body 111 is in the state 111-3, and the door 11 is open, close the door 11 and turn the key 127. An attempt to separate from the lock 125 is frequently attempted by another person. As described above, safety accidents may frequently occur due to functional differences between the safety slide key door lock and the general door lock.

Hereinafter, the key safety guard 110 according to an embodiment of the present invention will be described in detail.

8 is an exemplary view of a key safety guard according to an embodiment of the present invention.

Referring to FIG. 8 , the key safety guard 110 may be configured to include a key safety guard body 111 . One side of the key safety guard body 111 is composed of a fixed end 111a and the other side is composed of a free end 111b, and a hole 111c may be provided between the fixed end 111a and the free end 111b. 4, the key safety guard 110 may be configured to include two key safety guard bodies 111a and 111b.

The key safety guard body 111 should be disposed to primarily interfere with the key 127 for setting/unlocking the lock 125 and secondarily interfere with the door 11 or door post 12.

The key safety guard 110 is fundamentally different from the safety ring of the water opening prevention function attached to the apartment door. The safety ring functions to prevent the door from opening beyond a certain limit, but the key safety guard 110 functions to prevent the door from being opened, contrary to the function of the safety ring. The open prevention function of the key safety guard 110 is not continuous. When the secondary interference between the key safety guard body 111 and the door or door post is released, the door 11 may be converted to be openable. However, the first order interference must be canceled before the second order interference. The first interference corresponds to interference between the key 127 and the key safety guard body 111 to force possession of the key 127 and efficiently manage it.

Functionally, the key safety guard body 111 should put the door 11 in an openable state when the first interference is canceled and the second interference is canceled. That is, the key safety guard 110 enables the key 127 to be forcibly separated from the lock 125 to cancel the primary interference before opening the door 11 and enables the door 11 to be opened. It should have a structure that allows the secondary interference to be released through the position change of the body 111.

The fixed end 111a is an area provided with a rotating shaft 112 when the key safety guard body 111 changes its position, for example, when it rotates, in order to cancel the secondary interference of the key safety guard body 111. corresponds to

The free end 111b corresponds to an area where movement occurs when the key safety guard body 111 rotates in order to cancel the secondary interference of the key safety guard body 111 . That is, in the key safety guard body 111, the free end 111b rotates with respect to the rotating shaft 112 having the fixed end 111a.

The fixed end 111a and the free end 111a are characterized in that they are disposed at different positions. For example, when the fixed end 111a is fixed to the door post 12 side, the free end 111b may be positioned on the door 11 side to interfere with the opening of the door 11. Conversely, when the fixed end 111a is fixed to the door 11 side, the free end 111b is disposed on the door post 12 side and interferes with the door post 12 when the door 11 is opened. It can be.

The diameter of the hole 111c provided in the free end 111b should be arranged so as to interfere with the outer diameter of the key 127 of the safety slide key door lock 100, more specifically, the handle of the key 127. Accordingly, when the lock 125 coupled with the key 127 is provided on the side of the door 11 as shown in FIG. 3 , the free end 111b should also be disposed on the side of the door 11 together with the lock 125 . Conversely, when the lock 125 is provided on the door post 12 side as shown in FIG. 2 , the free end 111b should also be disposed on the door post 12 side together with the lock 125 .

The rotating shaft 112 serves to release the secondary interference of the key safety guard body 111 . That is, in the key safety guard body 111, secondary interference can be canceled through positional transformation of the free end 111b around the rotation shaft 112 provided at the fixed end 111a.

The rotating shaft 112 may be installed perpendicular to the surface of the door 11 or parallel to the door post 12 . Referring to FIGS. 5 and 6 , the rotating shaft 112 is installed to be perpendicular to the surface of the door 11 .
