Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a keyless locking device that can be unlocked without key operation.

[Prior Art] A keyless locking device as described above (in this case, for example,
As described in Japanese Unexamined Patent Publication No. 1-30864, a plurality of push buttons labeled with alphanumeric characters are arranged on an unlocking operation panel attached to the outside of the door, and a plurality of push buttons labeled with alphanumeric characters are arranged in a predetermined manner. Only when the pushbutton corresponding to the unlocking combination is pressed, the locking body such as a deadbolt retracts from the edge of the door and locks the door. It is now possible to open it.

A slide plate is provided in the above-mentioned unlocking operation panel, and a locking plate made of a small plate is attached to the rear of each push button, and these locking plates are provided on the slide plate. It is arranged so as to cross the sliding direction within the recess. Each locking plate has two positioning positions: a protruding position and a retracted position behind the protruding position, and when the push button is not pressed, it is fixed at the protruding position, while when the push button is pressed, When this is done, it is locked by the pressed position holding spring and placed in the retracted position.

Then, the intersection area with the slide plate at the protruding position (hereinafter referred to as
There is an opening through which the slide plate can be inserted when the slide plate moves upward in the first intersection area (hereinafter referred to as the second intersection area).
A first locking plate is formed with a shielding surface that prevents the sliding plate from moving upward, and a second locking plate is provided with a shielding surface in the first intersection area, which is opposite to the first locking plate. and second locking plates each having an opening formed in the intersection area.

Then, by installing the second locking plate on the rear of the push button corresponding to the unlocking combination, and installing the first locking plate on the rear of the other push buttons, Only when a push button that matches the above unlocking combination is pressed down, the slide plate is caused to move upward in conjunction with the knob operation, and in conjunction with the upward movement of the slide plate, it is retracted into the locking body. It seems that the movement is occurring.

In addition, a set bar is further disposed in the unlocking operation panel to release the locked state of each locking plate by the pressed position holding spring, and to cause a reset operation by the reset bar. A reset button is further arranged on the surface of the unlocking operation panel, and pressing the reset button causes a reset operation by the reset button via, for example, a cam.

[Problem to be solved by the invention]

However, in the above device, one of the pushbuttons arranged on the surface of the unlocking operation panel is used as a reset button, so the There is a problem that the increasing number of unlocking combinations is significantly reduced, or more space is required for the reset button on the surface of the unlocking operation panel, making it impossible to achieve sufficient compactness. In the case of the above device, the door would not open even if the knob was operated after the pushbutton was operated, and the user knew that there had been an error in the pushbutton operation and tried operating the pushbutton again. When starting from the beginning, there is a problem that the operation becomes complicated because it is necessary to press the above-mentioned seven-point button beforehand.5 The present invention has been made in consideration of the above-mentioned conventional problems. The object of the present invention is to provide a keyless locking device that can be made compact and have improved operability, as well as improved structural reliability.

[Means to solve the problem]

Therefore, the keyless locking device according to claim 1 of the present invention is as follows:
A plurality of push buttons arranged on a surface, a locking body that causes a retraction operation in response to a pressing operation of these pushbuttons, and a press-down position holder that locks the locking body in a retracted position after the retraction operation has occurred. and move this pressed-down position holder to release the locking state with respect to the locking body.] - The means and the door opening operation for the operation part for opening the door are performed in a predetermined combination as described above. In the keyless locking device, the keyless locking device is further provided with a slide plate that intersects with the locking body and slides in the unlocking operation direction in response to the door opening operation when the push button is pressed. An interlocking plate that interlocks with the operation section and a biasing means that urges the slide plate in the direction of unlocking operation are provided, and the interlocking plate includes a reset means that pushes the reset means when the operation section is operated. - A locking part and a locking part that locks on the slide plate when the operation part is not operated,
- A slide plate locking portion is provided which releases the locking state when the operation portion is operated.

Further, the keyless locking device according to claim 2 of the present invention is the device according to claim 1, further comprising an unlocking panel, and in which the relative displacement between the interlocking plate and the sliding plate is less than or equal to a predetermined amount. When the interlocking plate is locked to the unlocking panel in order to transmit the movement of the interlocking plate, when the relative displacement exceeds a predetermined amount, the interlocking plate operates so as not to release the locking state to the unlocking panel. It is characterized in that a connecting portion is provided between the unlocking panel and the interlocking plate.

[Function] According to the structure of claim 1 above, when the operation part that is operated to unlock the operation knob, operation lever, etc. is operated, the locked state of the slide plate by the interlocking plate is changed. As a result, if the push button operation according to the unlocking combination has been performed immediately before, this sliding plate will cause a sliding movement through each locking body by the biasing force of the biasing means. If a pushbutton operation that does not match the unlocking combination is performed, the locking body prevents the sliding movement. The interlocking plate interlocked with the operation section further includes:
Since the reset means is pushed, each locking body simultaneously returns to the protruding position and a reset state is provided.

In this way, in the above case, the reset operation is generated by operating the operation unit, and there is no need to provide a dedicated push button for Nanano as in the past, and all the push buttons arranged on the surface can be unlocked. Since it can be used for combinations,
It can be constructed with a more compact overall shape. Furthermore, since no dedicated reset operation is required, operability is improved.

In addition, in the configuration of claim 2, when the sliding movement of the sliding plate is blocked by the locking plate and the relative displacement between the interlocking plate and the sliding plate exceeds a predetermined amount, the interlocking plate is attached to the unlocking panel. No motion is transmitted, so this unlocking panel produces a similar movement as a sliding plate. In this way, in addition to the slide plate, an unlocking panel is used that operates only when the operation unit is operated in the unlocked combination state, and the operation of the unlocking panel moves the locking body, such as a deadbolt, in the unlocking direction. By configuring the locking body to be pushed and moved, the locking body is actuated directly by the operating force of the operating section, while the slide plate is actuated by the urging force of the urging means.

In other words, when a larger unlocking force is applied to the locking body as described above so that the unlocking operation occurs stably, but when the sliding movement of the sliding plate is blocked by the locking body. The force acting on the locking body from the slide plate, the force acting on the locking body, and the urging force of the urging means may be set in accordance with the strength of the locking body. As a result, the locking body can be made into a structure with lower strength, for example, a smaller size, without impairing reliability during unlocking, and this also allows the overall shape to be made more compact.

As shown in FIG. 11 and FIG. By connecting and fixing each other via the legs 57, the keyless locking device 5
is configured.

Next, the shape of the sensor chip 23 will be explained with reference to FIG. 15.

The sensor chip 23 is made of a hard plastic material such as polycarbonate, and includes, from the tip side (upper left side in the figure), a small-diameter cylindrical shaft portion 23a, a locking switching portion 23b with a substantially cross-shaped cross section, and a large-diameter cylindrical portion 23c. are manufactured in a shape that is successively connected in the axial direction. Among the four surfaces protruding radially from the axial center of the locking switching portion 23b, the surface extending horizontally to the left in the figure has a axial center line extending from the axial tip side to a predetermined axial position and from the side end surface to the axial center. A rectangular opening 23d recessed in the direction is formed, and a blocking surface 23e is provided at a position adjacent to the rectangular opening 23d on the rear side in the axial direction, and this surface is formed as a push release surface 23f. on the other hand,
On the surface extending vertically upward in H, there is a blocking surface 23e1 and a rectangular opening 23d° at the same axial positions as the rectangular opening 23d and the blocking surface 23e in the push-release surface 23f, respectively, in the opposite order to the above. are sequentially provided, and this surface is formed as a push-down non-release surface 23g.

On the other hand, two surfaces that are axially symmetrical to the push-release surface 23f and the push-down non-release surface 23g are first and second surfaces that are formed with spring locking portions 23h that protrude outward, respectively, at intermediate positions in the axial direction.
They are respectively formed as second positioning surfaces 23i and 23j. In addition, on the outer periphery of the large-diameter cylindrical portion 23c, there is an engagement that projects outward and extends in the axial direction at an angle of 45 degrees that bisects the circumferential distance between the push release surface 23f and the push non-release surface 23g. Protrusions 23k and 23k are formed.

The sensor chip 23 described above is assembled by inserting the shaft portion 23a into the insertion hole 22a of the reader case 22 from the outside of the door. A push button spring 58 made of a compression coil spring is disposed on the outer periphery of the tip end side of the shaft portion 23a protruding from the insertion hole 22a, and the push button 25 is attached so as to cover the tip side of the L rudder shaft portion 23a. is leader case 2
Attached to 2. The push button 25 has tongue-like protrusions 25a and 25a extending outward from the door, respectively, below -L on the rear end surface.
25a is provided, and these tongue-like protrusions 25a, 2
Locking protrusions 25b and 5b respectively protrude in the vertical direction at the tips of 5a.
25b is formed. As a result, the tongue-like projections 25a are inserted into the square holes 22b and 22b of the leader case 22.
・By pushing in 25a and positioning the locking protrusions 25b on the inner side of the door than the square holes 22b, -
The push button 25 is assembled to the leader case 22.

In this assembled state, the push button 25 is urged toward the outside of the door by the push button spring 58, and is held in a state of being locked to the leader case 22 by the locking protrusion 25b. When the push button 25 is pressed, it comes into contact with the tip of the shaft portion 23a of the sensor chip 23, causing the sensor chip 23 to move toward the inside of the door.

On the other hand, a setting button 24 is fitted into the inner end of the door of the sensor chip 23. The sending button 24 has a recess formed therein that is recessed from the outer end surface of the door and has approximately the same cross-sectional shape as the large-diameter cylindrical portion 23C of the sensor chip 23. When the large-diameter cylindrical portion 23c is fitted into these four parts, a sensor chip spring 59 made of a compression coil spring is compressed between the bottom surface of the recess and the end surface of the large-diameter cylindrical portion 23C.

The outer periphery of the setting button 24 has a shape in which a flange-like large-diameter disk portion 24a, a square cross-section portion 24b, and a small-diameter cylindrical portion 24c are successively connected from the outside of the door. After the setting button 24 is attached to the sensor chip 23, when the leader case cover 32 is assembled, the square cross section 24b is fitted into the square hole 32a of the league case cover 32. The assembled state is such that the periphery of the square hole 32a is in contact with the inner end surface of the door of the large-diameter disk portion 24a. This prevents the setting button 24 from being pulled out to the inside of the door, and the spring force of the sensor chip spring 59 acts as a force that urges the sensor chip 23 to the outside of the door. , the outer end surface of the door of the locking switching part 23b is held in a position where it contacts the reader case 22 (hereinafter, this position is referred to as the protruding position), and the cylindrical part 24c of the setting button 24 is
A slint groove 24d is further bored in the inner end surface of the door. For example, the slit groove 24d is formed in such a direction that it faces up and down when the push release surface 23f of the sensor chip 23 is located in the horizontal direction. Then, the tip of a tri-bar, for example, is fitted into the slit groove 24d, and pushed to the outside of the door so that the rectangular cross-section portion 24b separates from the square hole 32a of the league case cover 32, making it rotatable. By rotating the sensor chip 23 by 90 degrees, the sensor chip 23 is rotated by 90 degrees, thereby switching the push-down non-release surface 23g to a horizontal position.

Next, the above sensor chip 23 and the above sensor panel 31

Notch recess 31.31a. b
In the state where the sensor panel 31 is located inside, the upward movement of the sensor panel 31 is blocked by the blocking surface 23e. At this time, the tip of the locking protrusion 26b of the push-down position holding spring 26, which is located on the opposite side of the frame 31a with the sensor chip 23 in between, is in an axially symmetrical position with the push-down release surface 23f. It is located axially rearward than the spring locking portion 23h on the first positioning surface 23i.

Then, as shown in FIG. 17, when the push button 25 is pressed so that the spring locking portion 23h is located axially rearward of the locking protrusion 26b of the pressed position holding spring 26, Thereafter, while the sensor chip spring 59 returns to the front in the axial direction due to the spring force, the spring locking portion 23h engages the pressed position holding spring 26.
is locked by the tip of the locking protrusion 26b, and therefore,
It is held at a retracted position that is axially retreated from the protruding position. In this retracted position, the rectangular opening 23d axially forward of the blocking surface 23e is located at the position of the cutout recess 31b of the frame 31a of the sensor panel 31. Therefore, by operating the push button 25, the sensor panel 31 passes through the rectangular opening 23d.
It is designed to switch to a state where it can be moved upward.

On the other hand, as described above, when the setting button 24 is operated and the push-down non-release surface 23g is located in the horizontal direction, the sensor panel 31 becomes movable upward in the protruding position, contrary to the above. , from this state press button 2
When the pushing operation in step 5 is performed, the sensor panel 31
Switch to the upward movement prevention state.

In this way, the sensor chip 23, which can be switched between the movable state and the movement inhibited state of the sensor panel 31 in the -L direction, according to the operation of the push button 25, is located at the first position of the reader case 22.
They are provided for each of the four insertion holes 22a, and therefore these fourteen sensor chips 23...
The sensor panel 31 is actually moved only when all of the sensor panels 31 are movable to one side of the sensor panel 31.
This can cause movement in the opposite direction. For example, the 10th
In the figure, as shown by the direction of the slint grooves 24d on each end face of the 14 setting buttons 24, the four sensor chips 23 from the top of the right row in the figure are The push release surface 23f is the sensor panel 31
It is assembled by inserting it through the notch recess 31b (hereinafter referred to as
These four sensor chips 23... are referred to as a set chip group), and the other sensor chips 23... are in an assembled state in which the pressed non-release surface 23g is inserted through the notch recess 31b (hereinafter referred to as a set chip group). , these 10 sensor depths 23... are referred to as non-setting chip group), then from the state in which all sensor chips 23... are located at the protruding position (hereinafter referred to as the reset state), the four sensor depths 23 of the above-mentioned setting depth group are
Only when the push button 25 of the sensor depth 23 is pressed, the sensor panel 31
If one of the non-setting chips is further pushed in, the upward movement of the sensor panel 31 is prevented.

As shown in FIGS. 18 and 19, when the above-mentioned repressor h bar 2'N is moved upward, the protruding piece 26 of the press-down position holding spring 26 is moved as shown in the figure.
When b moves above the spring locking portion 23h of the sensor chip 23, the holding state of the retracted position by the locking protrusion 26b is released, and the sensor chip 23 is returned to the protruding position by the sensor chip spring 59. Each sensor chip 23... has a locking protrusion 26 (!...)
Since the reset part 27 is moved in one direction integrally with the reset part 27, the reset part 27 moves upward in the reset I state in which all the sensor chips 23 are located in the protruding position. given by action.

Next, the operating state of the keyless locking device 5 having the configuration described in "2" will be explained.

For example, in FIG. 10, the seven push buttons 25 in the right row have the following buttons in order from the top: ■, 2, 3, 4, 5, A-B. However, the seven pushbuttons 25 in the left column are 6, 7, 8, 9, 0, C-.
It is assumed that each alphanumeric code D is attached to the outer surface of the door, and the combination of the codes of the push button 25 that can make the sensor panel 31 upwardly movable (in the above case, the right column The following explanation will be given by referring to 1, 2, 3, 4) corresponding to the upper four sensor chips 23 as unlocking combination numbers.

First, press the pushbutton 25 that matches the unlock combination number above.
A case will be described in which the operation lever 8 is rotated after the operation is performed. At this time, the second
As shown in the figure, the retractor hub 28 rotates integrally with the square core shaft 10, and the tilting portion 28b of the retractor hub 28 rotates integrally with the square core shaft 10.
When the retractor 30 is tilted from the horizontal state shown in FIG. 1, the retractor 30 is pushed up in the -L direction against the spring force of the retractor spring 38. Along with this, the sensor panel 31 also moves in one direction. In other words, until then, the upward movement of the sensor panel 31 is prevented by the engagement surface portion 30d of the I-actor 30 coming into contact with the engagement bent portion 31e from above, and as described above. As the tractor 30 moves in the -1 direction, a pulling force by the sensor panel spring 42 is applied to the sensor panel 31. At this time, in all the sensor chips 23...
When the square openings 23d and 23d' of the sensor chips 23... are located at the intersection of the frame part 31a of the sensor panel 31, the frame part 3 ], a is inserted through these square openings 23d and 23d'. rises and the sensor panel 31
The whole body moves upward.

In this way, the sensor panel 31 along with the retractor 30 -
When moving in the L direction, the joint 29 attached to the retractor 30 is also brought into a state in which its right end surface is in contact with the right inner protrusion 33c of the unlocking panel 33 due to the spring force of the joint spring 40. hold and rise. In the middle of this toe-up, the two-wheeled portion of the unlocking panel actuating portion 29a at the joint 29 moves to the unlocking panel 3.
The actuated protrusion 33d of No. 3 comes into contact with the lower end surface of the protrusion 33d, and thereby,
Thereafter, this unlocking panel 33 is also pushed upward, and therefore, the unlocking operation bar 33b of this unlocking panel 33 moves upward. This unlocking bar 33
The lock 4, which will be described later, is unlocked by the folding movement of b.

In addition, during the upward movement of the above-mentioned glue tractor 30,
The locking surface portion 30d at the upper end of the retractor 30 comes into contact with the lower end surface of the reset bar 27, so that the reset bar 27 also moves upward a little later than the upward movement of the sensor panel 31. As a result, as shown in FIG. 18, with the frame 31a of the sensor panel 31 positioned within the rectangular opening 23d of the sensor depth 23, the sensor chip 23 is released from being locked by the push-down position holding spring 26. . As a result, the sensor chip 23, which had been held in the retracted position, moves forward to a position where the rear surface of the square opening 23d abuts the frame portion 31a.

Then, when the operating lever 8 is returned and the reset bar 27 is lowered, the tip of the locking protrusion 26b is lowered to a position behind the locking position of the spring locking portion 23h. As a result, when the sensor panel 31 is lowered and the notch recess 31b is at the same height as the sensor chip 23, the sensor depth 23 moves further forward through the notch recess 31b and returns to the initial protruding position. It becomes a cent state.

Next, the pushbutton 25 that does not match the unlock combination number
When an operation is performed on ..., and the sensor panel 3 is in a one-way state of no movement,
A case in which the operating lever 8 is rotated will be described.

In this case, as shown in FIG. 3, the retractor hub 28 rotates integrally with the square core shaft 10, and the retractor 30 is thereby pushed upward in the same manner as above, but
The sensor panel 31 is prevented from moving upward by one sensor chip 23 that does not match the combination number.

In this way, when the sensor panel 31 is held stationary and the tractor 30 moves upward, the joint 29, which rises together with the retractor 30 for three days as shown in the figure, On the way, the locking surface portion 29b comes into contact with the lower end of the locking protrusion 31i of the sensor panel 31, thereby preventing upward movement of the locking surface portion 29b. Therefore, from this point on, as the retractor 30 rises, the joint 29 rotates counterclockwise around the joint knock 39 against the spring force of the joint spring 40. . Therefore, the unlocking panel actuating portion 29a side of the joint 29 rotates toward the center, resulting in a state in which the unlocking panel actuating portion 29a contacts the actuated protrusion 33d of the unlocking panel 33 from below. It disappears. As a result, no upward movement occurs in the unlocking panel 33, and therefore the unlocking actuating bar 33b is held immobile.

In this case, as the retractor 30 rises, the locking surface portion 30d of the two wheels comes into contact with the lower end surface of the reset bar 27, and the action of pushing the reset bar 27 downward occurs in the same manner as described above. As a result, as shown in FIG. 19, the locking state of the sensor chip 23 by the locking protrusion 26b of the push-down position holding spring 26 is released. As a result, until then,
The sensor chip 23 held in the retracted position returns to the initial protruding position through the notch recess 31b of the sensor panel 31 and is set.

In this way, in the keyless locking device 5, the pushbuttons 25 that match the preset unlock combination number/month...
When operating the operating lever 8 after pressing the button 25, the unlocking bar 33b moves in the - direction, and the pushbutton 25 that does not match the unlocking combination number above.
When the pressing operation is performed, the unlocking operation bar 33b is held in an immovable state. Therefore, in conjunction with the operation of the unlocking bar 33b, the lock 4 has a function of retracting the deadbolt 3, as will be described later, and as a result, the door can be opened without using a key. It is possible to unlock from the outside.

As described above, each time the operating lever 8 is operated, the retractor 30 causes the reset I bar 27 to move upward, and therefore the operating levers 8 and 9 reset the sensor chimbu 23... It also functions as an operating section.

Next, the structure of the lock 4 will be explained.

As shown in FIG. 20, this lock 4 includes a rectangular plate-shaped front 61 fixed along the side end surface of the door 1, and a front reinforcing plate 62 fixed over the front 61.

A first latch hub spring 68 made of a compression coil spring is compressed between the end faces of the two cases 63, and the first latch hub spring 68 causes the pressure 67 to be applied to the right end face of the second case 63. It is urged in the right direction, that is, in the B direction, so that it is held in contact with the mating piece 65b.

On the other hand, a rendezvous tail 2a having a U-shaped cross section is disposed on the B-direction end of the first retaining piece 65a of the latch hub 65. This latch bolt tail 2a is fixed to the rear end side of the shaft portion 2b extending in the direction B from the front 61 side of the latch bolt 2,
A latch spring 69 made of a conical coil spring is installed between the latch bolt tail 2a and the inner wall surface of the case 63 in the B direction. The tip 2C is held at a position protruding from the front 61.

Furthermore, a temporary 70 is attached to the latch hub spring receiver in the shape of a 7 at a position intersecting with the shaft portion 2b of the latch bolt 2.
- It is disposed so as to be movable in the B direction. In this latch hub spring receiver, a second latch hub spring 71 made of a compression coil spring is disposed on the outer periphery of the shaft portion 2b between the vertical surface portion of the plate 70 and the tip portion 2C of the latch port 2. The plate 70 of the launch hub spring receiver is biased in the direction B by the second latch hub spring 71, so that the latch hub spring receiver temporarily contacts the left end surface of the first engagement piece 65a of the latch hub 65. held in contact. Further, a force larger than the counterclockwise force applied to the latch hub 65 by the first latch hub spring 68 is set to be applied from the second latch hub spring 71 to the launch hub 65, and as a result,
The latch hub 65 is held such that the right end surface of the first engagement piece 65a is in contact with the latch tail 2a.

On the other hand, above the dead bolt 3 in the case 63, there is a cylinder tail ll of the cylinder lock 11.
A punto hub 73 is provided which is rotated by b. This Punto hub 73 has an arm portion 73b extending diagonally downward to the right in the figure from its rotation center, and the lower end side of this arm portion 73b is inserted into the four portions 3a formed on the rear end side of the deadbolt 3. It is supposed to be located.

In addition, in order to guide the sliding movement of the deadbolt 3 in the A-B direction, a long hole 3b extending in the AB force direction is bored in the deadbolt 3, and a deadbolt guide is inserted into the long hole 3b. A knock 75 is installed upright on the case 63. And, in addition to this Dead Guide Nonku 75,
The upper right end side of the first actuating plate 76, which has an L-shape, is rotatably supported. On the lower end side of the first actuating plate 76, the latch hub spring receiver is disposed so that it is located close to the left side of the vertical surface of the plate 70 and approximately parallel thereto. Furthermore, the lower end side of a vertically long second actuating plate 77 is pivotally supported by a first notch 78 at the corner of the first actuating plate 76.
A second notch 80 is provided on the upper end side of the joint transmission gear 79 disposed on the A direction side of the Punto hub 73.
The shaft is supported by

The above-mentioned seven joint transmission gears have a substantially fan-shaped shape extending in the direction B from the side of the first guide knob 81 that rotatably supports the joint transmission gears, and a circular arc surface at the end in the direction B has a portion. A toothed portion 79a having a gear shape is formed. This toothed portion 79a is the cylindrical portion 7 of the dead hub 73.
It is assembled in a state in which it meshes with a toothed portion 73d similarly formed on the outer circumferential surface of 3a.

Furthermore, an abbreviated joint 82 is connected to the joint transmission gear 79. This joint 82
is rotatably supported by a second guide knob 83 at an intermediate position of the horizontal plate portion 82a. The lower end side of the vertical plate portion 821 extending downward from the left end side of the horizontal plate portion 82a is pivotally supported by the joint transmission gear 79 by a third notch 84, and as shown in the figure, the lower end side of the vertical plate portion 821 is
is the immersion position, that is, 1. When located in the unlocked position, the horizontal plate portion 82a is held in an inclined state with its right end side positioned upward.

A concave notch 85 is formed in the case 63 at a location to the right of the second guy I/knock 83, and the notch 85 has a gap in the L direction. The above-mentioned unlocking operation bar 33b extending from the unlocking operation panel 6 of the keyless locking device 5 is located.

In the lock 4 having the above configuration, when an operation that causes the square core shaft 10 to rotate clockwise, that is, an operation that pushes down the operating levers 8 and 9 is performed, the launch bolt 2 is moved to the front 61. The locked state by the Lande bolt 2 is released by moving in the B direction so as to be recessed from the front.

On the other hand, locking/unlocking of Deadpol l-3 is done using cylinder lock 1.
This is done by moving the lower end side of the arm portion 73b of the dead hub 73 fitted into the recess 3a of the dead bolt 3 in the AB force direction by the rotation operation A of the cylinder tail l1bO of No. 1.

Further, in the lock 4, an operation that causes the square core shaft 10 to rotate counterclockwise, that is, the operation lever 8
It is also possible to release the locking by the Punto bolt 3 even when an operation is performed in the direction of pulling it up to one side. In this case, as shown in FIG. 21, as the launch hub 65 rotates counterclockwise, the first engagement piece 65a of the latch hub 65
However, the latch hub spring receiver pushes the plate 70 in the direction A, and as a result, the first actuating plate 76 rotates clockwise.

Furthermore, the second actuating plate 77 is pushed up with the rotational movement of the gear, and as the second actuating plate 77 moves upward, the jigo point transmission gear 79 rotates counterclockwise around the first guide knob 81. Rotate. As a result, the dead hub 13 meshing with the toothed portion 79a of the gigopoint transmission gear 79 is rotated clockwise), and the punch bolt 3 is pushed in the projecting direction by the armature of the put hub 73 and the end ◇ze 1 of the put hub 73. Moved, 1 r.

and becomes locked.

In addition, in the locked state as shown in item 2, as the joint transmission gear 79 rotates, the horizontal plate portion 82a of the joint 82 is displaced to a substantially horizontal state, and its tip approaches the unlocking operation bar 33b. It will be located at

Further, in the locked state as described above, when an unlocking operation is performed by the keyless locking device 5 and the unlocking operation bar 33b moves upward, the unlocking operation is performed as shown in FIG. The tip end side of the horizontal plate portion 82a of the joint 82 is pushed down by the bar 33b, so that the joint 82 rotates counterclockwise about the second guide knob 83. As a result, the joint transmission gear 79 rotates clockwise around the first guide knob 81.
As the dead hub 73 rotates counterclockwise, the Punto bolt 3 is pushed in the B direction at the tip of the arm portion 73b of the dead hub 73. Due to dirt, the tip of this put-hold 3 is switched to the unlocked state where it is recessed from the Freon (.61).

At this time, since the square core shaft 10 is rotated clockwise by the operation of the operating lever 8, the launch port 1-2 is also brought into the retracted state in the same way as described in [1]I, and thereby,
Door 1 is opened and closed.

As described above, in the embodiment I, by operating the push buttons 25 arranged on the unlocking operation panel 6 in accordance with the unlocking association number set. ,
The door 1 can be opened and closed by unlocking from the outside of the door without using a key. And the above keyless locking device 5
In this case, the operation lever 8 also serves as a reset operation, and the reset operation occurs almost simultaneously when the operation lever 8 is operated. Therefore, there is no need to provide a dedicated reset pushbutton, etc., as in the past, and all the pushbuttons arranged on the surface can be used for unlocking combinations, allowing for a more compact shape and 2-piece configuration. Ru. In addition, if you realize that you have operated the push button 25 incorrectly because you are unable to open or close the door 1 after operating the operating lever 8, return the operating lever 8 and immediately check the unlock combination number. You can resume operations that suit your needs.
Unlike the conventional method, there is no need to perform additional operations using a reset button, which improves operability.

Furthermore, in the above keyless locking system 7I'5, the sensor panel 31 is slidable by the spring force of the sensor panel spring 42, in addition to the unlocking panel 33 which is directly slid by the operating force of the operating lever 8. It's starting to come alive. Therefore, ]2 Pressing the unlocking panel 33
1-While ensuring sufficient force, that is, unlocking force,
The spring force of the sensor panel spring 42 can be set according to the strength of the sensor depth 23. As a result, the sensor depth 23 can be made of a hard plastic molded body as described above, or can be made into a smaller shape, thereby making it possible to make the overall shape more compact. At the same time, it can be manufactured at a lower cost.

Note that the above embodiments do not limit the present invention, and various modifications can be made within the scope of the present invention. For example, the unlocking panel 33 may not be provided, and the sensor panel 31 may have an unlocking function
A configuration in which the JJ bar 33b is erected is also possible within the scope of claim 1 of the present invention. Further, in the above example, the switchable sensor depth 23 having the push release surface 23f and the push non-release surface 23g is provided as a locking body. Other configurations such as

〔Effect of the invention〕

As described above, the keyless locking device according to claim 1 of the present invention is provided with an interlocking plate that interlocks with the operating section and a biasing means that biases the slide plate in the unlocking operation direction, and the interlocking plate The device includes a reset locking portion that pushes the helical 1-means when the operating portion is operated, and a reset locking portion that locks onto the slide plate when the operating portion is not operated, and a reset locking portion that locks the sliding plate when the operating portion is not operated. This configuration is provided with a slide plate locking portion to be released.

Therefore, since the reset operation occurs simultaneously with the operation of the operation section, there is no need to provide a sensor I or dedicated button as in the past, and all the push buttons arranged on the surface can be used for unlocking combinations. It can be constructed in a more compact shape. In addition, since no dedicated reset operation is required, there is an effect that operability can be improved.

Further, the keyless locking device according to claim 2 of the present invention further includes an unlocking panel, and transmits the operation of the interlocking plate when the relative displacement between the interlocking plate and the slide plate is less than or equal to a predetermined amount. When the relative displacement between the moving plate and the sliding plate exceeds a predetermined amount, the connecting portion operates to prevent the locking state from being released from the unlocking panel. This structure is provided between the lock panel and the interlocking plate.

Therefore, the force that pushes a locking body such as a deadbolt in the unlocking direction acts from the unlocking panel via the operating section, interlocking plate, and connecting section, while the force acting on the sliding plate from the biasing means , the strength of the locking body can be made smaller in total. As a result, the locking body can be made into a structure with lower strength, such as a smaller size, without sacrificing reliability during unlocking, and this also has the effect of making the overall shape more compact. play.
