The clasp plate 16 is fixed to the rotor 15a at the base end, and the distal end extends outward from the clasp through slit 13a of the receiving member at the locking position to engage with the free edge 7 of the door panel when the door is closed. In the unlocked position, it fits inside the receiving member 3. The operation knob 17 has an operation shaft 17a that penetrates the operation shaft hole 14a and is coupled to the tip of the rotor 15a from the outside of the back plate 14. The key 18 is inserted into the key hole of the pin cylinder lock 15 from the key insertion hole 12a through the joint portion W4, and the pin cylinder lock 15 is locked and unlocked by forward and reverse rotation.

  According to the locking and unlocking apparatus of the invention according to this application, in the closed state, a smooth appearance without protrusions such as a handle for locking and unlocking operation can be obtained on the outside of the panel, while the door panel can be easily locked and unlocked from the outside. Can do. Further, even when the door is opened, there is no portion protruding from the peripheral edge of the opening, the appearance is good, and there are no obstacles when entering and exiting the opening.

It is a cross-sectional top view which shows the wall body provided with the locking / unlocking mechanism of the door panel which is one Example of this invention in a closed state. It is a cross-sectional top view of a part of locking mechanism in the wall of FIG. It is a vertical side view of a part of the locking mechanism in the wall of FIG. It is a one part perspective view of the locking mechanism in the wall of FIG. It is a disassembled perspective view of a part of locking mechanism in the wall of FIG.

Embodiments of the present invention will be described with reference to the drawings.
In FIG. 1, a number of metal panels supported by the spacers C are connected in a flush manner to form an indoor wall body W (only a part of which is shown in the figure). In order to open and close the opening W1 of the wall body W, the door panel 2 is suspended between the two studs C. The wall W has a front surface W2 and a back surface W3 opposite to the front surface. The front surface W2 is formed so that one surface thereof is substantially smooth except for the joint portion W4 in the vertical direction formed between the panels.

  The locking / unlocking mechanism 1 is for locking and unlocking between the door panel 2 and the receiving member 3 that receives the door panel 2, and includes a locking device 4.

  The door panel 2 is hung on one of adjacent studs C by a hinge 5 and can open and close an opening W1 between the adjacent studs, and is a substantially hollow box-shaped main body 6 and a free edge 7 of the main body 6. And a flange portion 8 extending continuously from the surface. A packing 8 b is fixed to the back surface side of the flange portion 8.

  The receiving member 3 has a lock receiving space 9 inside, is fixed to the other stud C, and abuts against the flange portion 8 of the door panel 2 when the door panel 2 is closed to form a series of wall bodies W. 2 to 4, the receiving member 3 includes a front surface plate portion 10, a facing edge 11, an abutting plate portion 12, an end edge plate portion 13, and a back surface plate portion 14, which are along the stud C. It is the structure which encloses the lock | rock accommodation space 9 in the square cylinder shape of a vertical direction.

  When the flange portion 8 of the door panel contacts the contact plate portion 12 when the door is closed, the surface plate portion 10 becomes flush with the surface of the flange portion 8.

  The facing edge 11 is orthogonal to the edge of the surface plate portion 10 and faces the edge so as to form a joint portion W4 in the vertical direction between the edge 8a of the flange portion 8 when the door is closed. To do.

  The abutting plate portion 12 forms a step with respect to the opposing edge 11 and extends at a right angle, and abuts against the back surface of the flange portion 8 when the door is closed, so that the surface plate portion 10 is arranged flush with the front surface of the flange portion 8. . The contact plate portion 12 has a key insertion hole 12a that penetrates the lock housing space 9 at a position corresponding to the joint portion W4.

  The edge plate portion 13 is orthogonal to the contact plate portion 12, has a slit 13 a for penetrating the stopper plate that penetrates the lock housing space 9 and faces the free edge 7 of the door panel body 6 in parallel when the door is closed.

  The back plate portion 14 has a shaft hole 14 a that is arranged in parallel to the opposite side of the front plate portion 11 and penetrates a shaft for operating the lock device 4 in the lock housing space 9. In the illustrated embodiment, the back plate 14 has an opening 14b, which is closed by a cover plate 14c. The opening 14 b is for assembling the lock device 4 in the lock housing space 9. A shaft hole 14a is formed in the cover plate 14c.

  The lock device 4 includes a pin cylinder lock 15, a stopper plate 16, an operation knob 17, and a bar key 18 for operation.

  As shown in FIGS. 2, 3, and 5, the pin cylinder lock 15 has a key hole corresponding to the key insertion hole 12 a of the receiving member, and the rotor 15 a is extended to the back surface side to enter the lock receiving space 9 of the receiving member. It is fixed. In the figure, reference numeral 19 denotes a mounting seat for the lock 15, which is welded to a position corresponding to the key insertion hole 12 a on the inner surface of the contact plate 12. The lock 15 is fixed to the mounting seat 19 with a nut 22 through a presser ring 20 and a presser plate 21.

  The base plate 16 is fixed to the rotor 15a at the base end, and rotates forward and backward in the range of 90 degrees between the locked position and the unlocked position integrally with the rotor 15a. The stopper plate 16 extends outward from the stopper penetration slit 13a of the receiving member at the locking position and engages with the free edge 7 of the door panel when the door is closed. Fits inside. The free edge 7 of the door panel 2 is formed with a slit 7 a that receives the front end side of the stopper plate 16. A sliding tongue piece 16a is provided on the base end side of the clasp plate 16, and its peripheral edge is in contact with a spring plate 23 fixed to the pressing plate 21, and resists rotation of the rotor 15a every 90 ° rotation. , The stopper plate 16 is held at the locked position and the unlocked position.

  The operation knob 17 is for operating the rotor 18 from the back side of the receiving member 3 and has an operation shaft 17a. The operation shaft 17a penetrates the operation shaft hole 14a from the outside of the back plate 14 and is coupled to the tip of the rotor 15a.

  The key 18 is formed in a thin rod shape and can be inserted into the key hole of the pin cylinder lock 15 from the key insertion hole 12a through the joint portion W4, and the pin cylinder lock 15 is locked and unlocked by forward and reverse rotation. Therefore, in the closed state, only the small key insertion hole 12a is exposed in the joint portion W4 on the surface side of the wall W, and the smoothness of the surface is not impaired.

  In the locking / unlocking mechanism 1 of the present invention configured as described above, when the door panel 2 is closed and locked from the surface W2 side of the wall body W, the door panel 2 is closed with the hand against the elasticity of the packing 8b. While maintaining the above, the key 18 is inserted into the keyhole from the gap of the joint portion W4 to rotate the pin cylinder lock 15 in the locking direction. As a result, the stopper plate 16 is rotated integrally with the rotor 15 a to the locking position against the elasticity of the spring plate 23, and is locked by being engaged with the slit 7 a of the door panel 2.

  On the other hand, when unlocking from the front surface side of the door panel 2, similarly, when the key 18 is inserted into the key hole from the gap of the joint portion W4 and rotated in the unlocking direction, the stopper plate 16 is released from the slit 7a of the door panel 2. The door panel 2 is automatically opened by being pushed by the elasticity of the packing 8b. Then, it can be operated to reach the edge of the door panel 2 and open it further. The door panel 2 may be automatically opened using a hinge that rotates and biases the door panel 2 in the opening direction.

  In addition, what is necessary is just to rotate the knob | pick 17 forward / reversely, when locking / unlocking from the back surface side of the door panel 2. FIG.
