Description

  The present invention is suitable for locks such as rockers, joinery, mailboxes, and valuables boxes, and can be manufactured in a small, lightweight and inexpensive manner. In addition, a plurality of operation buttons are annularly arranged on the front surface of the housing, and the center of the operation buttons is arranged. A lock shaft linked to the door lock and cylinder lock is rotatably arranged, and an operation handle is movably arranged on the peripheral surface of the housing to reduce the size of the housing or lock and improve the appearance of the door. The present invention relates to a button lock that can smoothly and quickly perform a series of operations from operation to operation of an operation handle.

Recently, keyless locks that do not use keys are widely used as door locks for houses, companies, station buildings, stores, hospitals, and the like.
Among the keyless type locks, the so-called mechanical lock, which is locked and unlocked by a mechanical method, does not require wiring and has a concern of securing a power failure or securing a power supply, compared to an electronic or electric lock that is locked and unlocked by an electrical method. Therefore, there is an advantage that the defense capability can be improved and the maintenance can be reduced, and the mechanical strength is high.

The mechanical lock is generally attached to a door, a plurality of push buttons and a door handle for setting a personal identification number are provided on the case frame, a main lock is provided inside the door, and the main lock is used to operate the push button. It has a structure for interlocking and unlocking.
In the mechanical lock, a plate-like block is attached to the surface of the case frame, a plurality of plate bodies are stacked inside the case frame, and a plurality of slits or through holes are formed in the plate body. Alternatively, a substantially S-shaped plate-like button with a slit formed in the through hole is inserted upright or inverted, and a cylindrical cover button is attached to the outside of the button, and a predetermined push button is memorized. Alternatively, there is one in which a password is set in a non-memory state (see, for example, Patent Documents 1 and 2).

However, the above-mentioned one has a plurality of cover buttons on the surface of the case frame placed outside the door, so that a lot of password information can be set and the defense capability is improved, but the case frame is enlarged and installed in a wide area. There is a problem that space is required and the use of the door is restricted by a door having a wide installation space.
Moreover, when setting or changing the security code, remove the block and case frame from the door to expose the button, disassemble the adjacent parts, recombine the upright or inverted state of each button, and insert the plate into the slit The case requires troublesome work and is easy to make a mistake due to the upright or inverted state of the buttons. In addition, the plates are stacked in sequence on the case frame and fixed together. The frame and each plate are inseparable, making it difficult to rationally produce or mass-produce them, and restricting the shape and dimensions of each part, resulting in a lack of freedom in case frame design. there were.

  As a mechanical lock to solve such a problem, a substantially prismatic push button locking device is provided on the front door of the mailbox, and this push button locking device has a plurality of push buttons arranged in the length direction of the surface. An irregular plate-shaped tumbler is arranged inside the push button so as to be movable inward and outward of the door, and a lock member formed with a plurality of uneven portions on one side of the tumbler is arranged so as to be movable in the length direction of the locking device. In addition, a clear actuating body that holds the pressing position of the tumbler is disposed on the other side of the tumbler, and the operation member that moves the lock member in the unlocking direction to the outermost position of the push button and the pressing position of the tumbler are released. Place the clear button in a row, press the push button corresponding to the PIN, and hold the pressed position, and put the latching piece protruding from the rear end of the lock member on the lid of the mailbox Latched to the holding member provided on the inner surface, there is that so as to lock the closed state of the lid member (e.g., see Patent Document 3).

However, since the push button locking device is formed in the shape of an elongated rectangular column, it can be used before locking a thin accessory container or the like, but the defense function depends on the number of push buttons, and there is a limit to the suppression of the number of push buttons. Therefore, there is a limit to the downsizing of the locking device.
In addition, the configuration in which a plurality of push buttons are arranged in a horizontal row makes the operation space horizontally long, which hinders smooth operation, while the operation member and the clear button are configured separately from the push buttons. For this reason, these functions are detected and mischievous, and there is a problem that the defense function is lowered.

Therefore, as a mechanical lock to solve the above problem, a plurality of operation buttons capable of inputting personal identification information are arranged on the surface of the case installed on the door so as to be able to be pressed, the operation buttons include a hollow cylindrical button case, A button gear rotatably inserted into the button case, and a plurality of latching pieces projecting from the lower peripheral surface of the button case, and a plurality of dogs projecting from the lower end of the button case, The button case is inserted into a button insertion hole provided on the surface of the case, the latching pieces are engaged with a plurality of guide ribs protruding from the inner surface of the insertion hole, and a plurality of gears and the dog are inserted in an intermediate portion of the button gear. The button gear can be rotated 45 ° by 45 ° when the button case is pressed, by inserting the lower end shaft of the button gear into the relay member protruding inside the back plate. The rotation angle is It has granted eight of the personal identification number of 0 to 7 in response to the pressing number of times.
On the other hand, the terminal gear and the reset gear are arranged inside the case so that they can be meshed, the reset gear is arranged so that they can mesh with the button gear, the rotational displacement of the button gear is transmitted to the reset gear, and the terminal gear can be rotated to the clutch shaft And a square hole of the terminal gear is detachably fitted to the square shaft of the shaft, and the cam shaft at the lower end of the clutch shaft is engaged with the shaft hole of the control cam. A notch groove that can be engaged with and disengaged from the engagement pawl is formed, and a lock plate is swingably connected to the control plate, and one end of the lock plate is provided to be engageable with a drive cam linked to the door handle. There is a button lock that can lock the movement of the lock plate (see, for example, Patent Document 4).

  However, this button lock can reduce the number of pushbuttons by half, and the case or button lock can be made compact as much as each pushbutton is given multiple passwords. Cover plate, back plate and control plate, lock plate, memory release link and many other parts are required. The structure is complicated and the assembly is complicated. Since the one end of the lock plate is linked to the operation handle and the coaxial drive cam, there is a possibility that the lock case or the button lock becomes long and the appearance of the door is impaired. Moreover, at the time of locking / unlocking, after operating the operation button, the finger is moved downward to rotate the operation handle, and thus there is a problem that a series of locking / unlocking operations lacks smoothness.

In addition, as another button lock, a lock case is attached to the vertical shaft of the inner door, and two operation buttons are arranged so as to be pressed at the upper and lower positions of the lock case, and the operation button has a hollow cylindrical shape.

A locking groove is formed on the surface, and a locking plate locking claw is provided in the locking groove so as to be able to be engaged and disengaged. There is a sickle lock for a sliding door in which a drive cam having a sickle attached to a piece is engagably disposed, and an operation handle is movably connected to the drive cam (see, for example, Patent Document 5).

  However, this conventional button lock can reduce the number of operation buttons to two, and a plurality of passwords can be assigned to each push button, so that the lock case or button lock can be made thin and compact. The operation handle is pivotably arranged, one end of the lock plate is linked to the operation handle and the coaxial drive cam, and the lower end of the lock plate is linked to the drive handle and the coaxial drive cam. The length of the lock case or button lock may damage the aesthetics of the door.In addition, when unlocking and unlocking, after operating the operation button, the finger is moved downward to rotate the operation handle. There was a problem that the lock operation was not smooth.

It is attached so that it can be engaged, and the rotation angle of the lock shaft 8 is restricted, and the square hole 87 of the lock plate 86 is fitted to the end of the square shaft 70. At that time, the mounting angle of the housing 6 is adjusted according to the rotation state of the lock plate 86, and the notch groove 29 is positioned vertically downward.

Then, a washer 90 and a spring washer 91 are disposed on the lock plate 86, bolts 92 are inserted into these, and screwed into the screw holes 71 of the lock shaft 8, and one end of the lock plate 86 is connected to the lock shaft 86. 8 is attached so as to be able to rotate in synchronization with the other, and the other end is detachably disposed in the vertically long lock holes 88 and 89 formed in the vertical frame 2 and the bent pieces 2 a and 3 a of the door 3.
This situation is as shown in FIG. 4, and the other end portion of the lock plate 86 is engaged with the lock holes 88 and 89 to lock the opening of the door 3. In this case, since the screw 11 is exposed on the front surface of the button lock 5, it is desirable to conceal this by a suitable means to prevent mischief of the screw 11.

When such a button lock 5 is used, desired password information is input to the operation button 22 in advance.
The password information is configured by selecting 4-digit password information. In the embodiment, the password information is configured by appropriately combining password numbers 1 to 8. In this case, it is also possible to use the same personal identification number repeatedly and select, for example, “1111” or “1122”. In the embodiment, “1234” is adopted as the personal identification number, the upper left operation button 22 is made to correspond to the personal identification number “1”, and the personal identification numbers “2”, “3”, “4” are sequentially set in the clockwise direction. It corresponds to the operation button 22 in the vicinity.

Therefore, the position of the operation button 22 corresponding to the personal identification number is specified, and even if the personal identification number “1234” is the same in appearance, when the position of the corresponding operation button 22 is different, for example, “2341”, “ 3412 "and" 4123 ".
In the embodiment, the upper left operation button 22 in FIG. 1 corresponds to the password “1”, the upper right operation button 22 corresponds to the password “2”, and the lower right operation button 22 corresponds to the password “1”. 3 ”, and the lower left operation button 22 is associated with the personal identification number“ 4 ”.

The password information thus selected is input by setting the button lock 5 attached to the door 3 to the unlocked state, for example.
In this case, the unlocked state of the button lock 5 is initially set to the code information “1111”, and the engagement between the lock ball 55 and the recess 67 of the lock shaft 8 is released as shown in FIG. It can be confirmed that the operation handle 7 and the lock shaft 8 are placed so as to be able to rotate synchronously, and that the personal identification number “1” is displayed on each display window 24 on the front surface of the button lock 5 in appearance.
At that time, if the unlocked state cannot be confirmed, the operation button 22 is pressed a predetermined number of times using the operation pin 94 and its holding portion 95 as will be described later, and the code number “1” is displayed on each display window 24. Let

Therefore, when inputting the personal identification number “1234” to the button lock 5, the holding portion 95 of the operation pin 94 is held, the operation pin 94 is inserted into the pin insertion hole 32 of the operation button 22, and the shaft end is stored. It is brought into contact with the change cam 51 and pushed in against the elasticity of the cam spring 76.
In this way, the cam spring 76 is compressed and the displacement memory change cam 51 moves in the same direction, and on the other side, the angular shaft 52 separates from the engagement groove 50 and engages with the memory change cam 51. The engagement of the groove 50 is released, and the relay member 39 can be rotated.
Under this condition, while the insertion state of the operation pin 94 is maintained, the end of the grip portion 95 is engaged with the operation button 22 in the vicinity corresponding to the personal identification number and pressed a predetermined number of times.

That is, since “1” is displayed in each display window 24 at the time of assembling the button lock 5, for the operation button 22 corresponding to the password information “1”, the password information “1” and “ "1", that is, the operation button 22 is pressed zero times, in other words, the original display is maintained without being pressed.
For the operation button 22 corresponding to the personal identification information “2”, “1” is initially displayed in the display window 24. Therefore, the difference between the personal identification information “2” and “1”, the operation button 22 is displayed. The operation button 22 corresponding to the password information “3” is pressed once, the difference between the password information “3” and “1”, the operation button 22 is pressed twice, and the password information “4”. Since “1” is initially displayed on the display window 24, the difference between the password information “4” and “1” and the operation button 22 are pressed three times.

Of the personal identification number “1234”, the operation button 22 corresponding to the personal identification number “1” is positioned in front of the memory change cam 51 at the upper right position in FIG. 40, and the operation button 22 at the same position is pressed zero times. In other words, the initial display is maintained without pressing.
In addition, the operation button 22 corresponding to the password information “2” is positioned in front of the storage change cam 51 at the upper left position in FIG. 40, and the operation button 22 at the same position is pressed once, and the password information “3”. 40 is located in front of the memory change cam 51 at the lower left position in FIG. 40, and the operation button 22 at the same position is pressed twice to operate the operation button 22 corresponding to the password information “4”. 40 is located in front of the memory change cam 51 at the lower right position in FIG. 40 and presses the operation button 22 at the same position three times.

  In this case, in the embodiment, the minimum “1” is initially displayed on each display window 24, and the display on the display window 24 is sequentially increased by the pressing operation of the operation button 22. When “3” of “1” or more is displayed, pressing is performed for the number of times from “3” to “1” through “8”, that is, six times, and “1” is displayed on the display window 24.

Thus, the operation button 22 corresponding to the password information “1” is pressed zero times, that is, the state at the time of assembly is maintained, and the operation button 22 corresponding to the password information “2” is pressed once to change the memory. After the engagement between the angular shaft 52 of the cam 51 and the engagement groove 50 is released and the relay member 39 is made rotatable, the operation pin 94 is further pushed in so that the end of the grip portion 95 is brought to the front of the operation button 22. Engage and press the operation button 22.
If it does in this way, the operation button 22, its dog 31, and the button gear 33 under engagement will be pushed together inside the housing 6, and the latching piece 30 and the guide rib 21 will cancel | release engagement.

After that, when the engagement between the square shaft 52 and the engagement groove 50 is released, the pressure of the operation pin 94 is loosened and pulled back forward, so that the button gear 33 and the operation button 22 are moved to the original position by the elasticity of the button spring 38. When the button gear 33 is returned to the original position, the cam face 36a is engaged with the taper surface at the tip of the guide rib 21, and the button gear 33 is equivalent to one pitch of the guide ribs 21 and 21, that is, Turn 45 °.
For this reason, the relay member 39 rotates synchronously with the button gear 33 around the support guide 46 via the prismatic support guide 46 fitted in the square hole 34 of the button gear 33. In the embodiment, the upper clock in FIG. The display seal 42 of the flange 40 is moved in the same direction, and the personal identification number of the display window 24 facing the flange 40 is switched from “1” to “2”.

Thereafter, when the operation pin 94 is pulled out from the pin insertion hole 32, the memory change cam 51 is pushed back by the elasticity of the cam spring 76, and the angular shaft 52 engages with the engagement groove 50 of the relay member 39.
In this case, the memory change cam 51 maintains the same phase position as that at the time of assembly, while the engagement groove 50 rotates 45 ° together with the relay member 39, but the center angle of each engagement groove 50 is 45 °. Therefore, even after the rotation, the position of each engagement groove 50 is kept in the same state as the beginning, and the angular shaft 52 is engaged with this engagement groove 50.
Accordingly, the memory change cam 51 maintains the same position as when the unlocking operation is initially performed, and the concave portion 54 is placed at the same position before and after the input of the password, and the lock button is located between the concave portion 54 and the concave portion 67 of the lock shaft 8. 55 is interposed.

  Next, the operation button 22 corresponding to the password information “3” is pressed twice. In this case, the operation button 22 is pressed once, the button gear 33 and the relay member 39 are rotated by 45 ° in the same manner as described above, and the personal identification number of the display window 24 is switched from “1” to “2”. Then, the operation button 22 is pressed once more, the button gear 33 and the relay member 39 are further rotated by 45 °, and the personal identification number of the display window 24 is switched from “2” to “3”.

Also in this case, the memory change cam 51 maintains the same phase position as that at the time of assembly. On the other hand, the engagement groove 50 rotates 90 ° together with the relay member 39, but the center angle of each engagement groove 50 is 45 °. Therefore, even after the rotation, the position of each engagement groove 50 is kept in the same state as the beginning, and the angular shaft 52 is engaged with this engagement groove 50.
Accordingly, the memory change cam 51 for the operation button 22 corresponding to the password information “3” maintains the same position as that at the time of the initial unlocking, and the recessed portion 54 is placed at the same position as before and after the input of the password number. And a lock ball 55 is interposed between the recess 67 of the lock shaft 8.

Further, the operation button 22 corresponding to the password information “4” is pressed three times. In this case, the operation button 22 is pressed once, the button gear 33 and the relay member 39 are rotated by 45 ° in the same manner as described above, and the personal identification number of the display window 24 is switched from “1” to “2”. Then, the operation button 22 is pressed once more, the button gear 33 and the relay member 39 are further rotated by 45 °, and the personal identification number of the display window 24 is switched from “2” to “3”.
Thereafter, the operation button 22 is pressed once more, the button gear 33 and the relay member 39 are further rotated by 45 °, and the personal identification number of the display window 24 is switched from “3” to “4”.

Also in this case, the memory change cam 51 maintains the same phase position as that at the time of assembly. On the other hand, the engagement groove 50 rotates 135 ° together with the relay member 39, but the center angle of each engagement groove 50 is 45 °. Therefore, even after the rotation, the position of each engagement groove 50 is kept in the same state as the beginning, and the angular shaft 52 is engaged with this engagement groove 50.
Therefore, the memory change cam 51 for the operation button 22 corresponding to the personal identification information “4” maintains the same position as that at the time of the initial unlocking, and the concave portion 54 is placed at the same position as before and after the personal identification number is input. And a lock ball 55 is interposed between the recess 67 of the lock shaft 8.

  Thus, even after the password “1234” is input, the lock ball 55 is interposed between the recess 54 of each memory change cam 51 and the recess 67 of the lock shaft 8, and the operation handle 7 and the lock shaft 8 are synchronized. It becomes possible to rotate, and the button lock 5 is placed in the unlocked state. This situation is as shown in FIG.

  Such input setting of the personal identification information can be performed by one-handed operation or pressing operation using the operation pin 94. Therefore, this can be easily performed, and the operation button 22 as in the case where the operating button 22 is pressed with a finger is used. Eliminate fingerprints, prevent detection of password information, and improve defense capabilities. In addition, whether or not the password information setting is appropriate can be easily and reliably confirmed visually by checking the password number 41 displayed on the display window 24 immediately after the input.

When the button lock 5 to which the password information is input and set is used to actually close and lock the locker door 3, the operation handle 7 is rotated to lock the lock plate 86 into the lock holes 88 and 89. After the engagement, one or more operation buttons 22 among the four operation buttons 22 are pressed once or more.
For example, when one operation button 22 is pressed once against the elasticity of the button spring 38, the operation button 22, the button gear 33, and the memory change cam 51 are pushed together into the housing 6 side.
Thereafter, when the pressing operation of the operation button 22 is released, the operation button 22, the button gear 33, and the memory change cam 51 are pushed back to the original positions by the elasticity of the button spring 38 and the cam spring 76.

  When the button gear 33 returns to the original position, the cam face 36a engages with the taper surface at the tip of the guide rib 21, and the button gear 33 corresponds to one pitch of the guide ribs 21 and 21, that is, 45 °. The relay member 39 rotates and synchronizes with the button gear 33 around the support guide 46 via a prismatic support guide 46 that is rotated and fitted into the square hole 34 of the button gear 33, and the flange 40 is displayed on the relay member 39. The seal 42 moves and the password of the display window 24 facing the flange 40 is switched from “1” at the time of unlocking to “2”.

Thus, when the relay member 39 is rotated by 45 °, the angular shaft 52 of the memory changing cam 51 that engages with the engaging groove 50 is synchronously rotated, and the concave portion 54 is moved in synchronism with the concave portion 67 of the lock shaft 8.
