Description

  The present invention is suitable for, for example, a sliding door or a single door sliding door lock in a home, factory, office, or station building, and reduces the number of parts and simplifies the configuration to reduce the size and weight and improve the appearance. The present invention relates to a sliding door lock that can quickly realize automatic locking at the time of closing, improve convenience and safety in use, and can enhance defense capability.

  As a conventional sliding door lock, a cylinder lock is attached to the middle and high positions of the vertical sliding of the inner sliding door, and a disk-like engagement portion is provided at the tip of a locking rod that can move with the rotor of the cylinder lock. Provided in the engagement hole of the receiving plate and the engagement hole formed in the middle and high position of the vertical wall of the outer sliding door so as to be able to advance and retract, and when locking, insert a key into the cylinder lock and rotate it around the axis to engage. There is one in which the joint portion is engaged with the outer edge portion of the engagement hole to lock the inner and outer sliding doors (see, for example, Patent Document 1).

  However, the sliding door lock locks the sliding door, for example, in a state where the pet is opened to a certain narrow width that allows pets to enter and exit. In addition to being uneasy about the security at the time of locking, there are problems that the key operation is required for locking and unlocking the sliding door.

  In addition, as another sliding door lock, a receiving bracket is attached to one of the sliding doors, a lock body is attached to the receiving bracket, and the opening of the other door is prevented by the thickness of the lock body, and the guide groove and the latch are attached to the receiving bracket. The lock body is provided with a latch piece that can be engaged with the latching portion, two sets of push button mechanisms, a lock ring and a push button type lock mechanism, and the latch ring abutment portion is engaged with the count portion of the lock ring. In addition, there is one in which a push button is pressed and unlocked corresponding to a password (for example, see Patent Document 2).

  However, the sliding door lock has a problem in that the structure is complicated and the number of parts is large, and it takes time and effort to manufacture and assemble.

  As a solution to such a problem, the sliding member is urged so as to be able to protrude on the door toe of the sliding door, and a latch that protrudes in accordance with the withdrawing / withdrawing operation of the member is provided on the door toe. The latch is provided so that it can be latched to the latching portion provided in the frame, and a lock member is provided to prevent the latch from being operated to the latch release side. The cylinder lock and the lock member are operated by operating the lock member from the outdoor side. There is a sliding door lock which can be locked and unlocked from inside or outside the room (for example, see Patent Document 3).

  However, the sliding door lock has a complicated structure and a large number of parts, and it takes time and effort to manufacture and assemble, and it is expensive, and the latch locking mechanism requires a large number of parts and their installation space. In addition, since the latch protrudes from the end face of the sliding door after the door is opened, there is a problem that clothes are caught on the latch to cause damage or contact with the body.

  In order to solve such a problem, a substantially L-shaped magnet mechanism is rotatably supported by the lock box, and is normally urged to be pivoted inward by a spring so that the magnet surface is exposed to the outside. When the door is closed, it is attracted to the magnet provided on the door frame and turns outward to allow the dead bolt to protrude from the lock box.When the door is opened, the magnet mechanism is turned away from the door frame and turned inward. Engage with the moving member to prevent the sliding member from moving to the door frame, move the shuttle plate to the outside, and rotate the second lever member to completely retract the dead bolt into the lock box. There is such a lock (see, for example, Patent Document 4).

  However, the lock has a complicated structure and a large number of parts, and it takes time and labor to manufacture and assemble, and is expensive.It is difficult to store the lock in the narrow door frame of the sliding door. There was a problem that the magnetic force was attenuated over time, the backward displacement of the deadbol when the door was opened was lowered, and the desired effect could not be obtained.

By the way, the applicant eliminates locks that are electrically or electronically operated, mechanically links all the components, strengthens the defense capability, and various keyless type button locks that can function effectively in an emergency. Developed and proposed.
For example, the button lock includes a plurality of push buttons for inputting personal identification information, a lock pin that moves together with the push button, and a key plate that engages and disengages the lock pin and performs locking and unlocking operations. The password information is input and stored in the button and locked, and the push button is pressed based on the password information to release the engagement with the key plate so that the lock can be unlocked (for example, Patent Document 5). reference).

  However, the button lock has a long and large case housing to be attached to the inside and outside of the door, and the smooth operation of the sliding door is impaired, and it is difficult to attach to the narrow door frame because of its poor appearance. It requires a solid lock that is linked to the operation of the internal and external lever handles, and a built-in rotating cam and dead bolt are incorporated into the lock, which helps increase the weight and cost of the sliding door. There was a problem.

The lever handles 27 and 30 or the square core rods 28 and 29 can be engaged with a latching claw, which will be described later, at one end of the latch catch 83 or the latch lock 84 depending on the rotation angle of the lever handles 28 and 29.
Then, the latch catch 83 or the latch lock 84 can be turned up and down with a pivot described later as a fulcrum according to the engagement displacement or rotation angle of the cams 81 and 82, and the rotation displacement can be held by a magnet described later. Has been.

  The latch catch 83 has a pivot that will be described later by the displacement of the square core 28 that moves in association with the turning operation of the lever handle 30 on the indoor side and the cam 81 of the cam shaft 77 that moves along with the square core 28. The latch lock 84 is pivotally supported by a fulcrum, and includes a square core rod 29 that moves together with the rotation operation of the lever handle 27 on the outdoor side, and a cam of a cam shaft 78 that moves together with the square core rod 29. By the displacement of 82, the pivot described later is made pivotable.

  The latch catch 83 and the latch lock 84 are formed into a substantially inverted L shape or a substantially Z shape by a zinc alloy die casting, which is a non-magnetic member, and the front shape of the latch catch 83 is substantially as shown in FIG. It is formed in a vertically long rectangle, and a pair of side pieces 85 project from the upper end of the rectangle.

A locking claw 85a is formed on the side portion of the side piece 85 so as to protrude rearward, and a circumferential end portion of the cam 81 is arranged to be engageable with an upper end portion of the locking claw 85a.
A concave curved engagement groove 86 is formed between the side pieces 85, 85, and the engagement groove 86 is disposed on the peripheral surface of the cam shaft 77 so as to be rotatable about the axis.
In the figure, reference numeral 87 denotes a pivot projecting outside the side piece 85. The pivot 87 is hooked on the pivot support grooves 65, 65 of the box bodies 45, 46 so that the latch catch 83 can be rotated around the pivot 87. I support it.

A substantially vertically long rectangular hole 88 is formed in an intermediate portion of the latch catch 83, and the pipe screw 31 and the screw 34 are accommodated in the elongated hole 88.
A rectangular magnet housing boss is provided at the lower end of the latch catch 83, and a rectangular concave hole 89 is formed inside the boss. A rectangular plate-shaped magnet 90 is accommodated in the concave hole 89, and its attracting surface is chrome-plated to be smooth, thereby reducing sliding friction with a magnet described later.

The magnet 90 is fixed by a steel screw 91, which is a ferromagnetic material, and prevents the magnetic field lines of the magnetic field from diffusing with a magnet, which will be described later, so that the flat attracting surface can be exposed from the square hole 67 to the outside. .
In the figure, 92 is a boss projecting from the back surface of the concave hole 89, and a screw hole 93 communicating with the concave hole 89 is formed therein.

  A spring receiver 94 is formed at an intermediate portion of the latch catch 83, and a latch spring 95 stronger than a later-described latch spring is accommodated in the spring receiver 94, and the other end of the spring 95 is seated on the back surface of the front plate 47. Through the elasticity, the latch catch 83 is urged so as to be rotatable about the pivot shaft 87 toward the inside of the sliding door 8.

On the other hand, the front shape of the latch lock 84 is formed in a substantially vertically long rectangle as shown in FIG. 7, and a pair of side pieces 96 project from the upper end portion thereof.
A locking claw 96a protrudes forward from the side portion of the side piece 96, and a circumferential end portion of the cam 82 is arranged to be engageable with a lower end portion of the locking claw 96a.
A concave curved engagement groove 97 is formed between the side pieces 96, 96, and the engagement groove 97 is disposed on the peripheral surface of the cam shaft 78 so as to be rotatable about the axis.
In the figure, reference numeral 98 denotes a pivot projecting from the rear end of the side piece 96. The pivot 98 is hooked on the pivot grooves 66, 66 of the box body 46 so that the latch lock 84 can be rotated around the pivot 98. I support it.

A substantially vertically long rectangular hole 99 is formed in the intermediate portion of the latch lock 84, and the pipe screw 33 and the screw 32 are accommodated in the elongated hole 99.
A circular magnet housing boss is provided at the lower end of the latch lock 84, a circular concave hole 100 is formed inside the boss, and a screw hole 101 is formed at the bottom of the concave hole 100.
A cylindrical magnet 102 is accommodated in the concave hole 100, and its attracting surface is polarized to a different polarity that can be attracted to the magnet 90, and the magnetic force is configured to be the same as the magnetic force of the magnet 90 The surface is chrome-plated to smooth the attracting surface and reduce sliding friction with the magnet 90.

The magnet 102 is attached by a steel screw 103, which is a ferromagnetic material, and prevents the magnetic field lines of the magnetic field from diffusing with the magnet 90, so that the flat attracting surface can be exposed to the outside from the square hole 68. ing.
In this case, the attracting area of the magnet 102 is formed smaller than the attracting area of the magnet 90, and the molding or assembling dimension error between the magnets 90 and 102 can be absorbed.

  A spring receiver 104 is formed at an intermediate portion of the latch lock 84, and a latch spring 105 is accommodated in the spring receiver 104. The spring 105 is weaker than the latch spring 95, and the other end is seated on the back surface of the front plate 48. Due to its elasticity, the latch lock 84 is urged so as to be rotatable inward of the sliding door 9 about the pivot shaft 98.

In this way, the latch catch 83 is pivotable in the vertical direction around the pivot 87 in conjunction with the operation of the indoor lever handle 30, and the latch lock 84 is connected to the outdoor lever handle 27. In conjunction with the operation, the pivot 98 can be pivoted up and down with the fulcrum as a fulcrum, and these displacements can be held in cooperation to form a locked / unlocked and opened state.
That is, when the sliding door is locked, the lever handle 30 on the indoor side is placed in a vertical state, and the cam shaft 77, the cam 81 and the square core rod 28 linked to the handle 30 are placed in a state where the rotation angle is 0 °. The both ends of the cam 81 are separated from the locking claw 85a by δ, and the engagement between them is released.

At that time, the latch catch 83 is rotated to the inside of the sliding door 8 with the pivot 87 as a fulcrum by the elasticity of the latch spring 95, and the magnet 90 at the lower end is located behind the square hole 67, that is, in the box body 45. The most part of the latch catch 83 is obliquely positioned in the sliding door 8. The lower end of the latch catch 83 is positioned so as to be engageable with the inner surface of the box body 45, and the rotation angle is restricted. The posture of the latch lock 84 that is attracted to the head is maintained. This situation is as shown in FIG.

On the other hand, the lever handle 27 on the outdoor side is placed in a vertical state when locked, and the cam shaft 78, the cam 82, and the square core rod 29 linked to the handle 27 are placed in a state where the rotation angle is 0 °. The portion is separated from the locking claw 96a by ε so that the engagement can be released.
Then, the magnet 102 at the lower end of the latch lock 84 is attracted to the magnet 90 of the latch catch 83 against the elasticity of the latch spring 105, and the magnet 102 protrudes rearward of the square hole 67. The sliding doors 8 and 9 are positioned so as to be engageable with the edge and the inner locking pieces 69 and 69 to prevent the sliding doors 8 and 9 from being moved or opened and closed. This situation is as shown in FIG.

  In this case, since the attracting surface of the magnet 90 is wider than the attracting surface of the magnet 102, it is possible to absorb an error in the molding dimensions of the magnets 90 and 102 and a dimensional error in the assembly of the latch catch 83 and the latch lock 84.

  Further, at the time of locking, both ends of the cam 81 are separated from the locking claw 85a by δ, and both ends of the cam 82 are separated from the locking claw 96a by ε. 30 can be quickly unlocked without load, and the unlocking operation from the indoor or outdoor side is urged, and the rotation angle of the latch catch 83 and the latch lock 84 with the pivots 87 and 98 as fulcrums is suppressed. The box body 45, 46 or the latch locks 83, 84 and the sliding doors 8, 9 are reduced in size and weight by suppressing the rotational displacement of the parts.

  The unlocking operation from the locked state can be performed from the indoor side or the outdoor side, can be unlocked by rotating the lever handle 30 from the indoor side, and the lock 25 can be unlocked from the outdoor side. After the unlocking operation, the lever handle 27 is rotated to be unlocked, and the latch catch 83 and the latch lock 84 can cooperate in the unlocking operation.

Among them, when unlocking from the indoor side, the lever handle 30 on the indoor side is rotated, and the square core rod 28 and the cam shaft 77 are moved in association therewith to enable the cam 81 to rotate.
At this time, when the rotation angle of the lever handle 30 is equal to or less than the distance δ, the cam 81 does not engage with the upper end portion of the locking claw 85a. The latch catch 83 and the latch lock 84 can be kept stationary through the attracted magnet 90 while maintaining the same posture as when locked.

Thereafter, the lever handle 30 is rotated to a value equal to or larger than the gap δ and equal to or smaller than θ ₁ , the end of the cam 81 is engaged with the locking claw 85a immediately below, and the locking claw 85a is pushed down. 4 is pivoted clockwise in FIG. 4, while the latch lock 84 is pushed back inward of the sliding door 9 via the magnet 102 attracted to the magnet 90, and the latch lock 84 is pivoted on the pivot 98 in FIG. 4. It can be turned clockwise. This situation is as shown in FIG.

Further, the lever handle 30 is rotated by θ ₂ (θ ₁ <θ ₂ ), the cam 81 is rotated to depress the locking claw 85a, and the latch catch 83 is rotated clockwise in FIG. The magnet 90 can be exposed vertically to the opening of the square hole 67, while the latch lock 84 is pushed back through the magnet 102 attracted to the magnet 90, and the magnet 102 is attracted to the square hole 68. It is possible to express vertically outside. This situation is as shown in FIG.

Thereafter, the lever handle 30 is rotated by θ ₃ (θ ₂ <θ ₃ ), the cam 81 is further rotated to push down the locking claw 85a, and the latch catch 83 is pivoted clockwise in FIG. And the attracting surface of the magnet 90 protrudes between the sliding doors 8 and 9 so that it can be unlocked.
On the other hand, the latch lock 84 is pushed back to the sliding door 9 side through the magnet 102 attracted to the magnet 90, the attracting surface of the magnet 102 is positioned between the sliding doors 8 and 9, and the attracting surface of the magnet 90, 102 is positioned vertically. Forms a locked state. This situation is as shown in FIGS.

Thus, at the time of unlocking, the attracting surfaces of the magnets 90 and 102 of the latch catch 83 and the latch lock 84 are positioned between the sliding doors 8 and 9, and the magnet 90 is attracted to the magnet 102 against the elasticity of the latch spring 95. The latch catch 83 is held in a substantially vertical posture.
Further, in the latch lock 84, the moment around the pivot axis 98 due to the elasticity of the latch spring 105 and the moment around the pivot axis 98 due to the gravity of the latch lock 84 antagonize, and the attracting surface of the magnet 102 is the front surface. It is located at the same level as the surface of the plate 48.

  At that time, the magnet 102 and the other end of the lower end portion of the latch lock 84 are positioned so as to be engageable with the inner surface of the box main body 46, restricting the push-back position of the latch lock 84, and to the square hole 68 of the latch catch 83. This prevents the protrusion of the door from being opened and ensures that the subsequent door can be opened.

On the other hand, when unlocking from the outdoor side, after unlocking the lock 25, the lever handle 27 on the outdoor side is rotated, and the square core rod 29 and the cam shaft 78 are moved together to rotate the cam 82. At this time, when the rotation angle of the lever handle 27 is equal to or less than the distance ε, the cam 82 does not engage with the lower end portion of the locking claw 96a, so that the latch lock 84 remains stationary. In addition, the latch catch 83 and the latch lock 84 can be kept stationary through the magnet 102 attracted to the magnet 90 while maintaining the same posture as when locked.

After that, the lever handle 27 is rotated to the clearance ε or more and φ ₁ or less, the end portion of the cam 82 is engaged with the lower end portion of the locking claw 96a directly above, and the locking claw 96a is pushed up. 4 is pivoted clockwise in FIG. 4 with the pivot 98 as a fulcrum, and the magnet 102 is pulled to the sliding door 9 side, while the latch catch 83 is pulled to the sliding door 9 side through the magnet 90 attracted to the magnet 102. 83 is pivotable clockwise in FIG. 4 with the pivot 87 as a fulcrum. This situation is as shown in FIG.

Further, the lever handle 27 is rotated by φ ₂ (φ ₁ <φ ₂ ), the cam 82 is rotated to push up the locking claw 96a, and the latch lock 84 is rotated clockwise in FIG. The magnet 102 is moved to position the attracting surface of the magnet 102 on the same plane as the front plate 47, and the latch catch 83 is pulled toward the sliding door 9 via the magnet 90 attracted to the magnet 102, and the attracting surface of the magnet 90 is moved to the front plate 47. Is positioned on the same plane. This situation is as shown in FIG.

Thereafter, the lever handle 30 is rotated by φ ₃ (φ ₂ <φ ₃ ), the cam 81 is further rotated to push up the locking claw 96a, and the latch lock 84 is rotated clockwise in FIG. And the attracting surface of the magnet 90 protrudes between the sliding doors 8 and 9 so that it can be unlocked. On the other hand, the latch catch 83 is pulled toward the sliding door 9 via the magnet 90 attracted to the magnet 102. The attracting surface is positioned on the same plane as the front plate 48, and the attracting surfaces of the magnets 90 and 102 are positioned vertically to form an unlocked state.
Such an unlocked state is as shown in FIG. 12, and this state is substantially the same as the case where the lever handle 30 is turned from the indoor side to unlock.

After the unlocking, the inner and outer lever handles 30 and 27 are held, and the sliding door 8 or 9 is moved in the opening direction to be opened.
For example, when the outer lever handle 27 is held and the sliding door 9 is moved in the opening direction, that is, in the leftward direction in FIG. Is done. In this case, instead of moving the sliding door 9 leftward in FIG. 1, the sliding door 8 may be moved rightward in FIG.
At that time, since the moment around the pivot 98 due to the elasticity of the latch spring 105 and the moment around the pivot 98 due to the weight of the latch lock 84 antagonize the latch lock 84, A similar state can be maintained.

On the other hand, in the latch catch 83, the magnet 90 is released from the magnetic field of the magnet 102, and the pivot spring 87 is turned counterclockwise by the elasticity of the latch spring 95 as shown in FIG. The rotation can be stopped when it competes with the surrounding moments. This situation is as shown in FIG.
This situation is the same when holding the inner lever handle 30 and moving the sliding door 8 in the opening direction to open it.

Thus, when the sliding door 9 is opened and the sliding door 9 is closed after a person enters or exits, for example, the lever handle 27 is held, and the sliding door 9 can be closed by moving it in the closing direction, that is, in the right direction in FIG. Yes.
That is, the sliding door 9 is moved in the closing direction, that is, rightward in FIG. 1, the vertical frame 17 is moved to the position opposite to the vertical frame 11 of the inner sliding door 8, and the magnetic fields of the magnets 102 and 90 influence each other. 15 is restored, the latch lock 84 rotates counterclockwise in FIG. 15 with the pivot 98 as a fulcrum against the elasticity of the latch spring 105, and the magnet 102 is attracted to the magnet 90 of the latch catch 83. A state similar to that at the time of locking can be formed.

On the other hand, the button lock which is the lock 25 is as shown in FIGS.
That is, the button lock includes a case housing 104 that defines the outside of the lock 25, a button press plate 105 that is stacked in the housing 104, and a lock plate 106 that performs a substantial locking function.

That is, the sliding doors 8 and 9 are arranged inside and outside, and these are movably attached to the left and right, and one vertical frame 11 and 17 is arranged to face each other when the doors are closed.
This state is as shown in FIGS. 1 to 4, and the interior seat 24 and the lock 25 are shorter than the conventional one, so that the appearance is good and the sliding doors 8 and 9 can be attached to a narrow space.

When the sliding doors 8 and 9 are attached in this manner and the vertical frames 11 and 17 are arranged to face each other, the square holes 67 and 68 of the front plates 47 and 48 attached to the vertical frames 11 and 17 are positioned to face each other. The rear magnet 90 and the magnet 102 at the opening of the square hole 68 face each other and attract each other.
At that time, as described above, the attracting surface of the magnet 90 of the latch catch 83 is located behind the square hole 67 and the attracting surface of the magnet 102 of the latch lock 84 is located at the opening of the square hole 68. The frames 11 and 17 can be arranged slightly opposite to each other with ease, and the sliding doors 8 and 9 can be easily attached to the inside and outside positions. This situation is as shown in FIG.

After the sliding doors 8 and 9 are attached, the strength of the latch spring 95 is much stronger than that of the latch spring 105, and there is no significant difference in the magnetic force of the magnets 90 and 102, that is, they are substantially the same. The latch lock 84 is attracted and moved to the latch catch 83 side with the pivots 98 and 98 as fulcrums against the elasticity of the latch spring 105, and the magnet 102 enters the square hole 67 through the square hole 68, and enters the magnet 90. Adsorb to the adsorption surface.
In this case, since the steel screws 91 and 103, which are ferromagnetic members, are attached to the centers of the magnets 90 and 102, the magnetic lines of force form a magnetic field that converges on the screws 91 and 103, thereby preventing the diffusion of the magnetic force. To do. This situation is as shown in FIG.

4, the lower end of the latch lock 84 enters the inside of the square hole 67 to prevent the sliding doors 8 and 9 from being opened, and the magnet 102 is attracted to the magnet 90 and latched with the latch lock 84 and the latch. Since the cooperative relationship of the catch 83 is strengthened, the sliding doors 8 and 9 cannot be opened even if the indoor lever handle 30 is rotated or moved in the left-right direction. Form a locked state.
At this time, since the lower end portion of the latch lock 84 is positioned so as to be engageable with the locking pieces 69 and 70, the position of the latch lock 84 at the time of locking is stabilized, and stable adsorption of the magnets 102 and 90 is promoted.

In addition, in the situation of FIG. 4, the password information is input to the lock 25 as described above, and the lock pin 173 input with the password prevents the lock plate 106 from moving upward, and the lock 25 forms a locked state. The outdoor lever handle 27 cannot be rotated, and the sliding door 9 cannot be opened.
Therefore, in the situation shown in FIG. 4, the opening of the sliding doors 8 and 9 is strongly prevented by the locked state of the lock 25 and the locking by the latch lock 84.

On the other hand, at the time such locking latch catch 83 as shown in FIG. 4 is positioned in the longitudinal direction slant in the latch control box L _1, the cam shaft 77 is disposed horizontally directed upward cam 81, The upper ends of the locking claws 85a and 85a are arranged directly below the both side ends of the cam 81 with a gap δ therebetween. This situation is as shown in FIG.
Further, as shown in FIG. 4, the latch lock 84 is positioned substantially vertically in the vertical direction in the latch control box L ₂ , the cam shaft 78 is disposed horizontally with the cam 82 facing downward, and is directly above both side ends of the cam 82. The lower ends of the locking claws 96a, 96a are arranged with a gap ε apart. This situation is as shown in FIG.

At the time of such locking, for example, when the sliding door 8 is opened from the indoor side, the lever handle 30 on the indoor side is rotated.
When the lever handle 30 is rotated, the square core rod 28 at the tip of the handle 30 is moved along therewith, and the cam shaft 77 fitted with the square core rod 28 is rotated.
At this time, when the rotation angle of the lever handle 30 is equal to or less than the angle corresponding to the gap δ, the latching claws 85a, 85a do not engage with both side ends of the cam 81, so the latch catch 83 uses the pivot 87 as a fulcrum. The state of FIG. 4 is maintained without rotating.

Thereafter, when the lever handle 30 is rotated by an angle equal to or greater than the gap δ (δ <θ ₁ <θ ₂ ), the end of the cam 82 in the rotational direction is engaged with the locking claw 85a immediately below. The latch catch 83 is pressed against the latch spring 95 by the engaging force, and pivots clockwise in FIG. 4 with the pivot 87 as a fulcrum, and its lower end presses the magnet 102 via the magnet 90 to latch lock. 84 is moved to the latch control box L ₂ side. This situation is as shown in FIGS. 9 (a) and 9 (b).

When the lever handle 30 is rotated by θ ₁ or more (θ ₁ <θ ₂ ), the end of the cam 81 in the rotating direction is engaged with the locking claw 85a immediately below, and further pressed down. As a result, the latch catch 83 resists the latch spring 95 and further pivots clockwise in FIG. 4 with the pivot 87 as a fulcrum, and its lower end presses the magnet 102 via the magnet 90, thereby latch-controlling the latch lock 84. Push it further to the box L ₂ side. This situation is as shown in FIGS. 10 (a) and 10 (b).
In the illustrated case, the latch catch 83 is positioned substantially perpendicular to the vertical direction in the latch control box L ₂ , the attracting surface of the magnet 90 moves to the opening edge of the square hole 67, and the attracting of the magnet 102 of the latch lock 84 is performed. The surface retreats to the opening edge of the square hole 67.

After that, when the lever handle 30 is rotated by θ ₂ or more (θ ₂ <θ ₃ ), the end of the cam 81 on the rotating direction side engages with the locking claw 85a immediately below and further pushes down. Due to the resultant force, the latch catch 83 resists the latch spring 95 and further pivots clockwise in FIG. 4 with the pivot 87 as a fulcrum, and its lower end presses the magnet 102 via the magnet 90 to latch the latch lock 84. Push it further to the control box L ₂ side. This situation is as shown in FIG. 11 (a) and FIG.

In this situation, the lower end portion of the latch catch 83 protrudes to the outside of the square hole 67, the attracting surface of the magnet 90 moves to the opening edge portion of the square hole 67, the latch lock 84 is further pushed and moved backward, The magnet 46 is close to the inner surface of the bottom of the main body 46 so as to be engageable, and the attracting surface of the magnet 102 is retracted to the opening edge of the square hole 68.
Accordingly, in the situation of FIG. 12, the magnet 90 of the latch catch 83 is attracted to the magnet 102 of the latch lock 84 retracted from the square hole 67, and the mooring relationship between the latch lock 84 and the latch catch 83 is maintained. Since the lower end part of this is retracted from the square hole 67, the substantial mooring relationship with respect to the sliding door 8 is released, and an unlocked state is formed.

Therefore, when the lever handle 30 is maintained at the rotation angle or slightly rotated to θ ₄ and the lever handle 30 is moved in the opening direction of the sliding door 8 against the attracting force of the magnets 90 and 102. The magnet 90 slides on the attracting surface of the magnet 102 and is separated from each other, and the sliding door 8 is opened.

Thus the sliding door 8 is open door, the latch catch 83 is rotated to the 12 dihedral clockwise pivot 87 as a fulcrum by the elasticity of the latch spring 95, located in an oblique shape in the longitudinal direction of the latch control box L ₁ The magnet 90 is positioned behind the square hole 67.
Further, the latch lock 84 maintains substantially the same state as when unlocked in FIG. 12 due to the elasticity of the latch spring 105, and the attracting surface of the magnet 102 is positioned at the opening of the square hole 68. This situation is as shown in FIG. 15 and FIG.
Therefore, after this, people can enter and exit from the open space of the sliding door 8.

On the other hand, after the sliding door 8 is opened, when the sliding door 8 is closed from the outside by using an appropriate grip portion, the vertical frames 11 and 17 of the sliding doors 8 and 9 face each other, and the front plate 47 attached to the vertical frames 11 and 17. , 48 are opposed to each other, and the magnet 90 behind the square hole 67 and the magnet 102 at the opening of the square hole 68 attract each other.
At this time, as described above, the attracting surface of the magnet 90 of the latch catch 83 is located behind the square hole 67 and the attracting surface of the magnet 102 of the latch lock 84 is located at the opening of the square hole 68. 8, 9 can be easily opened and closed.

  Thus, when the magnets 90 and 102 are opposed to each other, the strength of the latch spring 95 is very strong as compared with the latch spring 105 as described above, and there is no significant difference in the magnetic force of the magnets 90 and 102. Therefore, the latch lock 84 is attracted and moved toward the latch catch 83 with the pivot shafts 98 and 98 as fulcrums against the elasticity of the latch spring 105, and the magnet 102 enters the square hole 67 through the square hole 68. The magnet 90 is attracted to the attracting surface.

This situation is as shown in FIG. 4. Under this condition, the lower end of the latch lock 84 enters the inside of the square hole 67 to prevent the sliding doors 8 and 9 from being opened, and the magnet 102 is attracted to the magnet 90 and latches. Since the cooperative relationship between the lock 84 and the latch catch 83 is strengthened, the sliding doors 8 and 9 cannot be opened even if the indoor lever handle 30 is rotated or moved in the left-right direction. Forming a substantial locked state.
At this time, since the lower end portion of the latch lock 84 is positioned so as to be engageable with the locking pieces 69 and 70, the position of the latch lock 84 at the time of locking is stabilized, and stable adsorption of the magnets 102 and 90 is promoted.
That is, after the sliding door 8 is closed, the door is automatically locked, the opening of the sliding doors 8 and 9 from inside and outside is prevented, and safety is ensured.

On the other hand, when the sliding doors 8 and 9 are locked, for example, when the sliding door 9 is opened from the outdoor side, the lock 25 provided on the outdoor side is first unlocked.
When unlocking the lock 25, the button 26 corresponding to the password information input to the lock 25 is pressed. In the embodiment has entered the personal identification information of "14580A" in lock 25, to press via the button 26 the locking pin 173 corresponding to the dark certificate information based on the personal identification information display S _1.

For example, when the button 26 corresponding to the password information “1” is pressed, the flange portion engages with the button washer 112, the button washer 112 engages with the upper end portion of the lock pin 173, and the lock pin 173 is moved to the button. The spring 116 and the lock spring 162 are pushed down against the elasticity.
Therefore, the cone flange 176 pushes open the end portion of the reset spring 155 engaged with the reduced diameter side, and the lock pin 173 is pushed down in the axial direction. The reset spring 155 is a step portion on the large diameter side of the cone flange 176. The lock pin 173 is held in a pressed posture.
At that time, the cam flange 178 engages with the lock hole 136 of the lock plate 106, and the cam flange 177 on the other side engages with the lock pin hole 148 of the reset plate 107. This situation is as shown in FIG.

For example, when the button 26 corresponding to the password information “8” is pressed, the flange portion engages with the button washer 112, and the button washer 112 engages with the upper end portion of the lock pin 173, so that the lock pin 173 is engaged. Is pushed down against the elasticity of the button spring 116 and the lock spring 162.
For this reason, the cone flange 176 pushes open the end portion of the reset spring 155 engaged with the reduced diameter side, and the lock pin 173 is pushed down in the axial direction, and the reset spring 155 is placed on the large diameter side step portion of the cone flange 176. Engage and hold down the lock pin 173.

At this time, the cam flange 178 engages with the lock hole 135 of the lock plate 106, and the cam flange 177 on the other side engages with the lock pin hole 148 of the reset plate 107. This situation is as shown in FIG.
Thereafter, the button 26 corresponding to the other password information “4”, “5”, “0”, “A” is pressed in the same manner, and the corresponding lock pin 173 is pressed down.

If the button 26 is pressed incorrectly during the unlocking operation, that is, if the non-password input button 26 is pressed, the clear button 111 is pressed as a cancel or correction operation, and the clear is performed via the enlarged diameter edge 111a. The button washer 113 is pressed, and the clear pin 181 that engages with the button washer 113 is pressed down.
Then, the taper surface 182a of the taper flange 182 projecting from the clear pin 181 is engaged with and pressed against the taper surface 157a of the clear pin insertion hole 157, and the reset plate 107 is moved upward against the reset spring 159. Move to the left.

In this way, the reset spring 155 moves with the reset plate 107, and its end portion is separated from the lock pin 173 or the cone flange 176 to release the engagement between them, so that each lock pin 173 is moved by the lock spring 162. Pushed up against the button spring 116, the reset spring 155 is engaged with the small diameter side of the cone flange 176, and the lock pin 173 of the button 26 that has been erroneously operated is restored to its original state at the time of non-password input, and the button that has been properly operated 26 lock pins 173 restore the original state when the password is input.
Therefore, after that, based on the password input information, the button 26 is pressed again to perform the unlocking operation.

When the button 26 or the lock pin 173 corresponding to the password information “14580A” is pressed in this way, the cam flange 178 is inserted into the lock hole 135 corresponding to “8”, “0” in the first row of the lock plate 106. The cam flange 178 is positioned in the same manner as the cam flange 177 of the lock hole 135 in the same row.
This situation is as shown in FIG. 37, in which one side ends of the cam flange 177 and the cam flange 178 are engaged with the protrusion 139 on the upper portion of the lock hole 135, and the other side ends thereof are separated from the engaging edge portion 138. Therefore, the lock plate 106 is allowed to move upward.

In addition, the cam flange 178 enters the lock hole 136 corresponding to “1”, “4”, “0”, “A” in the second row of the lock plate 106 in an inverted state instead of the cam flange 177. The cam flange 178 is positioned similarly to the cam flange 177 of the lock hole 136 in the same row. This situation is as shown in FIG. , And the other end portions thereof are separated from the engaging edge portion 138 to allow the lock plate 106 to move upward.
Therefore, in this situation, the lever handle 27 can be rotated, and the unlocked state of the lock 25 is formed.

After unlocking the lock 25, for example, when the sliding door 9 is opened from the outdoor side, the lever handle 27 on the outdoor side is rotated.
When the lever handle 27 is rotated, the square core rod 28 at the tip of the handle 27 is moved along therewith, and the cam shaft 78 fitted with the square core rod 28 is rotated.
At this time, when the rotation angle of the lever handle 27 is equal to or smaller than the angle corresponding to the gap ε, the latching claws 96a and 96a do not engage with both side ends of the cam 82, so the latch lock 84 uses the pivot 98 as a fulcrum. The state of FIG. 4 is maintained without rotating.

Thereafter, when the lever handle 27 is rotated by an angle equal to or greater than the gap ε (ε <φ ₁ <φ ₂ ), the end portion of the cam 82 in the rotating direction is engaged with the locking claw 96a directly above. The latch lock 84 is pushed up by the engaging force, and the latch lock 84 resists the latch spring 105 and pivots in the clockwise direction in FIG. 4 with the pivot 98 as a fulcrum. By suction, the latch catch 83 is pulled toward the latch control box L ₂ side. This situation is as shown in FIGS. 13 (a) and 13 (b).

When the lever handle 27 is rotated by φ ₁ or more (φ ₁ <φ ₂ ), the end of the cam 82 in the rotating direction is engaged with the engaging claw 96a immediately above and further pushed up, and the engagement force As a result, the latch lock 84 resists the latch spring 105 and further pivots counterclockwise in FIG. 13 with the pivot 98 as a fulcrum, and its lower end further retracts from the square hole 68 to attract the magnet 90 to the magnet 102. Te pull the latch catch 83 to the latch control box L ₂ side. This situation is as shown in FIGS. 14 (a) and 14 (b).
In the illustrated case, the latch catch 83 is positioned substantially vertically in the vertical direction in the latch control box L ₁ , the attracting surface of the magnet 90 is positioned at the opening edge of the square hole 67, and the magnet 102 of the latch lock 84 is The suction surface is retracted to the opening edge of the square hole 67.

Thereafter, when the lever handle 27 is rotated by φ ₂ or more (φ ₂ <φ ₃ ), the end of the cam 82 in the rotating direction is engaged with the engaging claw 85a immediately above and further pushed up. Due to the resultant force, the latch catch 83 opposes the latch spring 105 and further pivots counterclockwise in FIG. 14 with the pivot 98 as a fulcrum, and the lower end of the latch catch 83 retracts from the square hole 68, thereby Push it further to the ₂ side. This situation is as shown in FIG. 11 (a) and FIG.
In this situation, the lower end portion of the latch catch 83 protrudes outside the square hole 67, the attracting surface of the magnet 90 is retracted from the opening portion of the square hole 68, and the magnet 90 is attracted to the magnet 102 to latch the latch catch 83. Pull to the control box L ₂ side. This situation is as shown in FIG. 11 (a) and FIG.

Accordingly, in the situation of FIG. 12, the magnet 90 of the latch catch 83 is attracted to the magnet 102 of the latch lock 84 retracted from the square hole 68, and the mooring relationship between the latch lock 84 and the latch catch 83 is maintained. Since the lower end part of this is retracted from the square hole 68, the substantial mooring relationship with respect to the sliding door 9 is released, and an unlocked state is formed.
Therefore, lever - maintaining the rotation angle of the steering wheel 27, or slightly pivoted phi _4, the lever - the handle 27 against the attracting force of the magnet 90,102 moves pulling the opening direction of the sliding door 9 when The magnet 102 slides on the attracting surface of the magnet 90 and is separated from each other, and the sliding door 9 is opened.

When the sliding door 9 is thus opened, the latch lock 84 maintains the same state as when unlocked in FIG. 12 due to the elasticity of the latch spring 105, and the attracting surface of the magnet 102 is positioned at the opening of the square hole 68. .
The latch catch 83 is rotated to the 12 dihedral clockwise pivot 87 as a fulcrum by the elasticity of the latch spring 95, located in the slant stationary back-and-forth direction of the latch control box L _1, the magnet 90 is It is located behind the square hole 67. This situation is as shown in FIGS. 15 and 16B. Therefore, after this, the entrance / exit from the open space of the sliding door 9 becomes possible.

On the other hand, when the lever handle 27 is rotated to open the door, the end portion of the flat surface 190a of the drive cam 190 is engaged with the bent piece 142 of the lock plate 106, and the lock plate 106 is opposed to the lock spring 147. Push up.
Then, the cam flanges 177 and 178 of the lock pin 173 engage with the opening edges 135a and 136a of the lock holes 135 and 136, thereby preventing the lock plate 106 from moving upward.

Further, when the lever handle 27 is rotated to open the door as described above and the drive cam 190 is moved, the reset plate 107 is moved via the protruding piece 156 placed on the flat surface 190a of the drive cam 190. It is pushed up against the reset spring 159.
For this reason, the reset spring 155 moves together with the reset plate 107, and the terminal portion thereof is separated from the lock pin 173 or the cone flange 176 to release the engagement therebetween.

Then, each lock pin 173 is pushed up against the button spring 116 by the lock spring 162, the reset spring 155 is engaged with the small diameter side of the cone flange 176, and each lock pin 173 restores the original state at the time of password input.
Therefore, after that, even if the lever handle 27 is rotated back to the original position and the sliding door 9 is closed, the password input information of the lock 25 is maintained and the locked state can be formed.

On the other hand, when the sliding door 9 is closed from the outside after the sliding door 9 is opened, the vertical frames 11, 17 of the sliding doors 8, 9 face each other, and the square holes 67 of the front plates 47, 48 attached to the vertical frames 11, 17. 68 face each other, and the magnet 90 behind the square hole 67 and the magnet 102 at the opening of the square hole 68 attract each other.
At that time, as described above, the attracting surface of the magnet 102 of the latch lock 84 is located at the opening of the square hole 68 and the attracting surface of the magnet 90 of the latch catch 83 is located behind the square hole 67. 8, 9 can be easily opened and closed.

  Thus, when the magnets 90 and 102 are opposed to each other, the strength of the latch spring 95 is very strong as compared with the latch spring 105 as described above, and there is no significant difference in the magnetic force of the magnets 90 and 102. Therefore, the latch lock 84 is attracted and moved toward the latch catch 83 with the pivot shafts 98 and 98 as fulcrums against the elasticity of the latch spring 105, and the magnet 102 enters the square hole 67 through the square hole 68. The magnet 90 is attracted to the attracting surface.

  This situation is as shown in FIG. 4. The lower end of the latch lock 84 enters the inside of the square hole 67 to prevent the sliding doors 8 and 9 from being opened, and the magnet 102 is attracted to the magnet 90 and latched with the latch lock 84 and the latch. Since the cooperative relationship of the catch 83 is strengthened, the sliding doors 8 and 9 cannot be opened even if the outdoor lever handle 27 is operated to rotate or to be moved in the left-right direction. Form a locked state.

  At this time, since the lower end portion of the latch lock 84 is positioned so as to be engageable with the locking pieces 69 and 70, the position of the latch lock 84 at the time of locking is stabilized, and stable adsorption of the magnets 102 and 90 is promoted. That is, after the sliding door 9 is closed, it is automatically locked and the opening of the sliding doors 8 and 9 from inside and outside is prevented.

Note that the password information of the button lock of the lock 25 may be perceived by long-term use, so it is desirable to change it periodically.
In that case, the lock 25 is removed from the sliding door 9, and the lock display slit 180 of the lock pin 173 corresponding to the new password information among the lock pins 173 exposed on the back surface of the cover plate 108 is inserted into the plate. 108, and the other lock pin 173 positions the code display slit 180 on the outside of the plate 108. This change operation is performed in the same manner as when the password information is input, and the lock 25 may be attached to the sliding door 9 after the password information is changed.

  As described above, the sliding door lock according to the present invention reduces the number of parts, simplifies the structure, reduces the size and weight, reduces the cost and improves the appearance, and does not require the conventional full lock, and also automatically locks when the door is closed. Can be realized promptly to improve convenience and safety in use.
