Description

The present invention relates to a cylinder lock.

Patent Document 1 discloses a cylinder lock in which a lock coupling body is directly engaged with an input part for operating a lock mechanism arranged in a door, and an operating force to a plug inserted into a cylinder case is transmitted to the input part. The one described in is known.

In this conventional example, the paddle (lock coupling body) is slidably fitted onto the shaft provided on the coupling part fixed to the cylinder case, and has a position where the tip locks on the key rotor (input part) and a position at the base of the shaft. It moves between a lock release position located on the end side and the lock release position where the lock with the input section is released.

The lock coupling body is urged toward the locking position by a coil spring, and is temporarily held at the locking release position by being locked by a regulating piece that rotates together with the plug.

To attach the cylinder lock to the door, move the cylinder lock to the specified position while holding the lock connection body in the unlocked position, and then lock/unlock the cylinder lock to release the locking by the restriction piece. This is done by releasing the lock connecting body to project it to the locking position and connecting the lock connecting body to the input part of the locking mechanism section.

JP2019-108731A

However, in the conventional example described above, when connecting the lock connector to the input part, it is necessary to operate the plug, so an unlock key is prepared to rotate the plug when installing it on the door. There is a problem that the efficiency of the assembly work is low due to the necessity of assembly.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a cylinder lock with good assembly workability.

According to the present invention, the above objectives are:
a coupling body holder 3 connected to a plug 2 inserted into the cylinder case 1;
It has a lock connection body 4 held by a connection body holder 3,
The lock connection body 4 has a locking position where it can lock onto an input part 7 of a lock mechanism part 6 disposed in the door 5 and transmit a rotational operating force to the plug 2 to the input part 7;
The plug is biased towards the locking position and can be moved in the axial direction of the plug 2 between the lock release position where the plug 2 is retracted from the locking position and released from the input section 7, and the lock is released. can be restrained in position;
This is achieved by providing a cylinder lock in which the coupling body holder 3 is provided with a release operation part 8 for releasing the restraint of the lock coupling body 4 to the unlocked position.

The cylinder lock has a plug 2 that is inserted into a cylinder case 1 and can be rotated by a genuine unlocking key 15, and a lock coupling body 4 that rotates together with the plug 2. It is used to operate the lock mechanism 6 by locking the lock coupling body 4 to the input section 7 of the lock mechanism 6 that maintains the closed state.

A connecting body holder 3 that rotates as the plug 2 rotates is connected to the plug 2, and a lock connecting body 4 is slidable on the connecting body holder 3 along the axial direction of the plug 2, and is connected to the door 5. A locking position in which the door 5 protrudes inward and locks on the input part 7 in the fixed state, and a locking release position in which the door 5 retreats toward the outer panel 5a side and the input part 7 is unlocked. move between.

The lock connector 4 is biased toward the locking position, that is, toward the protruding position, and can be restrained in the unlocked position by appropriate means against the biasing force, and the connector holder 3 By operating the disposed release operation section 8, the restraint can be released and moved to the locking position.

In the present invention, in which the lock connecting body 4 can be held in the unlocked position where the lock connecting body 4 is moved back toward the outer panel 5a from the locked position, the total length of the cylinder lock with the lock connecting body 4 held in the unlocking position is When set appropriately, the cylinder lock or the input section 7 of the lock mechanism section 6 can be relatively moved along the back surface of the outer panel 5a without interfering with each other while the lock coupling body 4 is held in the unlocked position. becomes possible.

As a result, when attaching the cylinder lock to the door 5, the cylinder lock and the lock mechanism part 6 are moved relative to each other along the back surface of the outer panel 5a while the lock connector 4 is held in the unlocked position, and both are attached to the door. 5 to a position where it faces directly in the thickness direction, the lock coupling body 4 may be moved to a locking position by operating the release operation section 8, and the cylinder lock may be coupled to the lock mechanism section 6. Since this becomes possible, the workability of assembling the door 5 is improved.

Furthermore, the operation of moving the lock connector 4 to the locking position can be completed only by operating the release operation section 8 disposed on the connector holder 3, and no other operation is required. The workability of attaching is improved.

Furthermore, the lock coupling body 4 can be configured to be restricted from moving toward the unlocked position at the locked position.

The lock coupling body 4 is biased toward the locking position, and once moved to the locking position, it remains in the locking position due to the biasing force and remains locked with the input section 7 of the locking mechanism section 6. However, in order to prevent inadvertent release of the lock from the input section 7 due to movement to the lock release position due to vibration or the like, it is necessary to increase the biasing force.

On the other hand, if the biasing force is increased, an operation force that resists the large biasing force is required when setting the locking device to the unlocked position, which is the initial posture, resulting in a problem that workability deteriorates.

On the other hand, if the movement of the lock coupling body 4 from the locking position to the locking release position is restricted by an appropriate stopper means, the lock coupling body 4 is moved to the locking position by applying the biasing force to the release operation section 8 and releasing the restraint. Since it is sufficient to set the force to a size sufficient to cause the force to move, the biasing force can be reduced, and as a result, work efficiency is improved.

moreover,
The release operation unit 8 is operable to move from a lock position corresponding to a restraint state to the lock release position of the lock coupling body 4 to an assembly position beyond the lock release position corresponding to a restraint release state,
The lock connector 4 is held in the locking position by operating the release operation part 8 to the unlock position, and has a cylinder lock that can be removed from the connector holder 3 when the release operation part 8 is in the assembled position. Can be configured.

In this case, the lock connection body 4 is restrained in the unlocking position with the release operation part 8 in the lock position, and when the release operation part 8 is moved from the lock position to the lock release position, the lock connection body 4 is It moves to the unlocked position, and is held at that position by being prevented from detaching from the coupling body holder 3 by an appropriate stopper means. Thereafter, when the release operation section 8 is moved to an assembly position beyond the unlock position, the restriction by the stopper means is released and the lock connector 4 can be separated from the connector holder 3.

As a result, the lock coupling body 4 can be easily attached to and detached from the coupling body holder 3 while the release operation part 8 is operated to the assembly position, so that the efficiency of assembling the cylinder lock is improved.

Further, the cylinder lock is configured such that the operation of the release operation portion 8 from the unlock position to the assembly position is impossible by continuous operation from the lock position to the unlock position, and the release operation from the lock position to the unlock position is impossible. By making the operation on the part 8 different from the operation on the release operation part 8 from the unlocking position to the assembly position, the operation for connecting the cylinder lock and the locking mechanism part 6 and the operation for assembling the cylinder lock can be performed in a series. Cannot be executed as an operation.

As a result, when the cylinder lock and the locking mechanism section 6 are connected, the lock connector 4 will not be inadvertently detached from the connector holder 3, that is, the cylinder lock will not be disassembled.

moreover,
The lock coupling body 4 is provided with a first stopper part 9 and a second stopper part 10, and the coupling body holder 3 is provided with a stopper body 11 that can be operated from a lock position to an unlock position by a release operation part 8. installed,
The stopper body 11 includes a first piece 12 that restricts the stroke end of the first stopper portion 9 on the locking position side to restrict separation of the lock connector 4 from the connector holder 3;
At the locked position, the second stopper part 10 is restricted from moving in the direction of the locked position to hold the lock coupling body 4 in the unlocked position, and at the unlocked position, the second stopper part 10 is allowed to move in the direction of the locked position. A cylinder lock comprising two pieces 13 can be constructed.

In this configuration, the stopper body 11 is disposed on the coupling body holder 3, and can be moved from the lock position to the unlock position by operating the release operation section 8. The stopper body 11 is provided with a first piece 12 and a second piece 13, and these first and second pieces 12 and 13 allow the first and second stopper parts 9 provided in the lock coupling body 4, The state of the lock coupling body 4 is controlled by opening and closing the movement path 10.

Also,
The stopper body 11 is urged toward the lock position, and
When the first piece 12 constitutes a cylinder lock that restricts movement of the lock connecting body 4 in the locking position toward the locking release position, the stopper body 11 resists the urging force by operating the release operation part 8. After driving the lock coupling body 4 to the locking position by operating the stopper body 11 to the lock release position, when the operating force on the release operation part 8 is released, the stopper body 11 returns to the lock position by the biasing force.

In this state, the first piece 12 restricts the movement of the lock connector 4 toward the unlocked position and holds the lock connector 4 in the lock position.

As a result, even without increasing the urging force applied to the lock connector 4, the lock connector 4 can be prevented from being unlocked from the input section 7 due to inadvertent movement toward the unlock position due to vibration or the like. can be held in the locked position.

Holding of the lock coupling body 4 in the locking position by the first piece 12 can be achieved by providing the lock coupling body 4 with a suitable stopper part, and the second stopper part 10 can also be used.

moreover,
The stopper body 11 is operable to move beyond the unlocked position to the assembly position,
The first piece 12 can constitute a cylinder lock that allows the first and second stopper parts 9 and 10 to pass through in the assembled position, and allows the lock connector 4 to be detached from the connector holder 3.

In addition, cylinder locks,
The stopper body 11 can be moved from the lock position to the unlock position to the assembly position by pressing the release operation part 8 with a finger,
In addition, the connecting body holder 3 can be configured to be provided with a regulating wall 14 that regulates the movement path of the releasing operation section 8 from the unlocking position to the assembly position from being pressed by a finger.

According to the present invention, it is possible to facilitate the connection operation with the lock mechanism section, and it is possible to improve the workability of assembling the door.

FIG. 6 is a diagram showing a state in which the connecting body is locked to the input section.

FIG. 1 shows a handle device (H) using the cylinder lock (CY) of the present invention. The handle device (H) is fixed to the door 5 to operate a locking mechanism 6 provided in the door 5 to maintain the closed state of the door 5, and has an operating handle 17 connected to a handle base 16. It is formed.

The handle device (H) in this example is configured as a so-called flush surface handle in which only the operation handle 17 appears on the surface of the door 5, and the handle device (H) is fixed to the door 5 so that only the operation handle 17 appears on the surface of the door 5. This is done by fixing the base 16 to the back surface of the outer panel 5a.

In this example, the locking mechanism section 6 is configured to release the closed state of the door 5 by an unlocking operation on the input section 7, that is, an operation using a cylinder lock (CY), or an operation to open the door 5 using the operating handle 17. However, it is also possible to provide only the function of rejecting or allowing the opening operation of the door 5 using the operation handle 17 in response to the operation of the input unit 7 using the cylinder lock (CY).

As shown in FIG. 2, the operating handle 17 is connected to the handle base 16 via first and second links 18 and 19, and is driven by a drive cam from the initial state shown in FIG. 2(a) by an electric actuator (not shown). 20, the operation handle 17 can be driven to a position where it protrudes from the surface of the door 5, that is, the outer panel 5a (see FIG. 2(b)).

As shown in FIG. 2(c), when the operating handle 17 is rotated in the direction of the arrow around the pivot 19b using the elongated hole 19a formed in the second link 19 from this state, it is integrally attached to the second link 19. The actuating portion 19d of the connected auxiliary link 19c rotates the actuating lever 21 around the rotation axis (C21), actuating the transmission member 22 such as a cable device, and actuating the locking mechanism portion 6.

The cylinder lock (CY) is shown in Figure 3 and below. The cylinder lock (CY) is inserted into the cylinder case 1, has a plug 2 that can be rotated by a genuine unlocking key 15, and is fixed to a handle base 16 in the cylinder case 1.

As shown in FIG. 4, the rear end of the plug 2 (hereinafter, in this specification, the direction facing inward of the door 5 when attached to the door 5 is referred to as "rear", and the outer panel 5a side is referred to as "front"). ), the connecting body holder 3 is connected to the connecting body holder 3 using a connecting pin 23 (a spring pin in this example). In order to connect the connecting body holder 3, a pin insertion hole 24 is provided at the rear end of the plug 2, and the pin insertion hole 24 has a semicircular shape at both ends and is elongated in the front-rear direction. The connecting pin 23 with possible diameter dimensions is fixed to the connecting body holder 3 at both ends.

As shown in FIG. 4(a), the pin insertion hole 24 is formed in such a shape that the long axis gradually becomes shorter toward the center, and the connecting body holder 3 connected by the connecting pin 23 is As shown in FIG. 4(b), the connecting pin 23 can be rotated around the central axis (C23) (in the direction of the arrow in FIG. 4(b)). Rotation (rotation in the direction of the arrow in FIG. 4C) in a plane perpendicular to the rotation plane around the central axis (C23) of the pin 23 is allowed.

As a result, misalignment between the cylinder lock (CY) and the input section 7 of the lock mechanism section 6 is absorbed, and connection reliability is improved.

Further, at the rear end of the plug 2, a forward biasing force is applied by an elastic member 26 held at the innermost part of a plug insertion recess 25 recessed forward in a cylindrical portion 3a of a connecting body holder 3, which will be described later. By applying a biasing force to the plane of the rear end of the plug 2, the plug 2 and the connecting body holder 3 become aligned in a straight line due to the elastic force.

As shown in FIG. 5 and below, a lock connector 4 is connected to the connector holder 3. As shown in FIG. As shown in FIG. 6, the lock connecting body 4 has a spherical portion 4a at the rear end, a cylindrical connecting portion 4b at the front end, and an outer diameter approximately equal to the outer diameter of the connecting portion 4b at the middle portion. Each has a circular flange 4c, and a small diameter portion 4d smaller in diameter than the connecting portion 4b is formed between the flange 4c and the connecting portion 4b.

The spherical portion 4a of the lock connector 4 has a locking protrusion 4e that can be locked in a locking recess 7a of the input portion 7, which will be described later, and a first stopper portion that also serves as a rotation stopper at the front end of the connector 4b. 9 are formed respectively, and the stepped portion between the connecting portion 4b and the small diameter portion 4d is used as the second stopper portion 10.

Further, as shown in FIG. 5(a), a spring accommodating recess 4f for accommodating a compression spring 27, which will be described later, is formed on the front end surface of the connecting portion 4b.

On the other hand, the connecting body holder 3 is formed by protruding a cylindrical part 3a forward from the front end surface of the stopper holding part 3b, and a plug insertion part into which the rear end part of the plug 2 is inserted is inserted into the front end of the cylindrical part 3a. A recess 25 is provided, and the above-mentioned elastic member 26 is fixed to the innermost part (rear end) of the plug insertion recess 25 .

Further, the stopper holding portion 3b is provided with a paddle insertion recess 28 that is open to the rear end surface and reaches the middle portion of the cylindrical portion 3a. As shown in FIG. 5(b), this paddle insertion recess 28 has a circular portion 28a through which the flange 4c of the lock connector 4 and the locking protrusion 4e can pass, and a circular portion 28a through which the first stopper portion 9 can pass. A spring receiving protrusion 29 that enters into the spring accommodating recess 4f of the lock coupling body 4 is protruded from the bottom wall (front end surface).

With the above configuration, the lock connector 4 is inserted into the connector holder 3 through the paddle insertion recess 28 opened at the rear end of the connector holder 3 with the compression spring 27 supported by the spring receiving protrusion 29. It can be assembled, and when it is attached to the connecting body holder 3, it moves in the front-rear direction between the unlocking position shown in FIG. 5 and the locking position shown in FIG.

In order to control the position of the lock coupling body 4 within the coupling body holder 3, a stopper body 11 is attached to the stopper holding portion 3b of the coupling body holder 3. As shown in FIGS. 5 and 7, the stopper body 11 includes a first piece 12 protruding from the rear end edge of the substantially rectangular flat support piece 11a, and a second piece 12 protruding from the front end edge of the support piece 11a. A release operation portion 8 extending in the front-rear direction is bulged in the center of the support piece 11a.

In addition, a pair of restriction wall insertion openings 11b are formed at opposite positions in the center of the support piece 11a so as to sandwich the release operation part 8 therebetween, and at both side edges of the support piece 11a, the push-in side of the stopper body 11 is opened. A stroke stopper 11c for determining the end of the stroke is provided in a protruding manner, and a regulating wall 14 is further provided in the connecting body holder 3 in a protruding manner, passing through the regulating wall insertion opening 11b.

On the other hand, as shown in FIGS. 5A and 5B, a stopper holding recess 30 is formed in the stopper holding part 3b of the coupling body holder 3, and the stopper holding recess 30 is separated by the wall surface of the paddle insertion recess 28. The body 11 is attached to the connector holder 3 by inserting the first and second pieces 12 and 13 into a stopper insertion opening 31a formed in a partition wall 31 between the stopper holding recess 30 and the paddle insertion recess 28.

The stopper body 11 attached to the coupling body holder 3 is movable in a plane perpendicular to the axial direction of the lock coupling body 4, and can be moved to a locked position shown in FIG. 5, an unlocked position shown in FIG. 8, and a position shown in FIG. As shown in FIG. 3, the stroke stopper 11c of the stopper body 11 moves between assembly positions where it abuts against the partition wall 31.

Further, a compression spring 32 is interposed between the partition wall 31 and the back surface of the support piece 11a of the stopper body 11, and the stopper body 11 is biased in the direction of removal from the connecting body holder 3.

The first and second pieces 12 and 13 of the stopper body 11 are provided with a first opening 12a and a second opening 13a. As shown in FIG. 5, the second opening 13a of the second piece 13 has the lock connecting body 4 in the unlocked position (the protrusion dimension of the lock connecting body 4 from the connecting body holder 3 is the minimum (zero in this example)). As shown in FIG. 5(d), the small diameter portion abutting edge 13b abuts against the small diameter portion 4d of the lock coupling body 4, and is attached in the removal direction by the compression spring 32. The biased stopper body 11 is prevented from coming off from the coupling body holder 3 by pressing the small diameter portion abutting edge 13b against the small diameter portion 4d, and is held at the lock position.

As shown in FIG. 5(d), in this state, the second stopper portion 10 of the lock coupling body 4, which is urged backward by the compression spring 27, comes into contact with the second piece 13 of the stopper body 11, and its movement is restricted. In order to do so, the lock link 4 is held in the unlocked position.

The second opening 13a is formed in a shape through which the lock connecting body 4 can pass except when the stopper body 11 is in the locked position, and as shown in FIG. When the stopper body 11 is moved to the lock release position by pushing down against the biasing force of being pushed out.

On the other hand, when the stopper body 11 is in the unlocked position, parts other than the first stopper part 9 can pass through the first opening 12a, and only when the stopper body 11 is in the assembled position, the first stopper part 9 can pass through. As shown in FIGS. 8(b) and 8(d), when the stopper body 11 is operated from the lock position to the unlock position and the lock coupling body 4 is moved rearward, the first The stopper portion 9 collides with the first piece 12.

The position of the lock connection body 4 where the first stopper part 9 is held in contact with the first piece 12 corresponds to the locking position, and in this position where the lock connection body 4 is protruded inward from the door 5 when attached to the door 5, the position shown in FIG. As shown in FIG. 11(c), the locking protrusion 4e of the lock coupling body 4 locks into the locking recess 7a provided in the input section 7 of the locking mechanism section 6, and the operating force to the plug 2 is reduced. The signal is transmitted to the lock mechanism section 6.

Furthermore, when the operating force on the stopper body 11 is released from the state shown in FIG. 8, the stopper body 11 moves to the lock position due to the restoring force of the compression spring 32, and as shown in FIG. The lower edge of the lock connector 12a comes into pressure contact with a stopper surface 4g formed on the lock connector 4.

In this state, the first piece 12 prevents the lock connection body 4 from being inadvertently unlocked due to vibration or the like in order to block the movement path of the second stopper portion 10 of the lock connection body 4 in the direction of the unlocking position. This effectively prevents the locking mechanism section 6 from being disconnected from the input section 7 due to movement toward the position side.

Furthermore, as described above, since the first opening 12a is formed in a shape that allows the first stopper part 9 to pass through when the stopper body 11 is in the assembled position, as shown in FIG. By operating the body 11 to the assembly position, the restraint of the first stopper portion 9 by the first piece 12 is released, so that the lock coupling body 4 can be separated from the coupling body holder 3.

Therefore, with the stopper body 11 held in the assembled position, the lock coupling body 4 is inserted into the coupling body holder 3 and pushed to the lock position, and then the stopper body 11 is simply released from the operating force. 11 returns to the locked position by the restoring force of the compression spring 32 and is held at the unlocked position, so that the lock coupling body 4 can be easily assembled.

When the stopper body 11 is assembled to the coupling body holder 3, the compression spring 32 urges the stopper body 11 toward the lock position, and as described above, the small diameter portion abutting edge 13b of the second piece 13 contacts the small diameter portion of the lock coupling body 4. 4d to prevent rattling.

Further, as shown in FIG. 8, the regulating wall 14 of the connecting body holder 3 is set at a height such that its tip is approximately flush with the top surface of the release operation part 8 when the stopper body 11 is pushed down to the unlocking position. Further, as shown in FIG. 8(d), the interval (W) between the regulating walls 14 is set to be narrower than the width of the finger (F).

Therefore, when the release operation part 8 is pressed down from the lock position with the finger (F), when the stopper body 11 reaches the lock release position, the press operation with the finger (F) becomes impossible, and the stopper body 11 is substantially The end of stroke to the unlocked position is determined. Therefore, in order to further operate to the assembly position, it is necessary to press down the release operation part 8 using an appropriate tool that can be inserted between the regulating walls 14, as shown in FIG. 10(b). .

As a result, it is completely possible to prevent the lock coupling body 4 from separating from the coupling body holder 3 due to the stopper body 11 being accidentally operated to the assembly position during the coupling operation of the cylinder lock (CY) to the locking mechanism section 6. It can be prevented.

In addition, in the above, a case is shown in which the operation to the assembly position is changed by switching the pressing operation to the assembly position from the pressing operation by the finger (F) to the pressing operation by a tool, but in addition to this, for example, It is also possible to configure the release operation section 8 to be pressed down until the lock release operation, and to move from this state to the assembly position by sliding in a direction perpendicular to the direction of the pressing operation.

FIG. 11 shows a method of attaching the handle device (H) configured as described above to the door 5. First, in this example, the input part 7 of the lock mechanism part 6 is arranged in advance at a predetermined position inside the door 5, and the lock connector 4 of the cylinder lock (CY) fixed to the handle device (H) is engaged. It is held in the unlocked position.

The handle device (H) is assembled to the door 5 by moving the handle device (H) along the back surface of the outer panel 5a of the door 5, as shown in FIG. It is fixed to the outer panel 5a by suitable fixing means (not shown) at a position substantially directly facing the input part 7 in the thickness direction of the door 5.

The cylinder lock (CY) is formed in such a size that the lock connector 4 does not interfere with the input section 7 when the lock connector 4 is moved along the movement path along the back surface of the outer panel 5a in a state where the lock connector 4 is in the unlocked position. In this example, in which the lock coupling body 4 is housed in the coupling body holder 3 in the locked position, the rear end surface of the coupling body holder 3 is fixed to the handle device (H) when it is assembled in the handle base 16 of the handle device (H). It is formed to a size that does not interfere with the input section 7 by a movement operation to a position (sliding operation along the back surface of the outer panel 5a).

In this state, when the release operation part 8 is pushed down with a finger toward the unlock position, the lock connector 4 protrudes toward the center of the thickness of the door 5 and moves to the lock position, and the lock protrusion 4e It is locked in the locking recess 7a of the input part 7, and thereafter, the rotational operating force to the plug 2 can be transmitted to the locking mechanism part 6.

Furthermore, even if there is an error in the fixing position between the handle device (H) and the input section 7, the plug 2 and the connecting body holder 3 can be connected by the connecting pin 23 as shown in FIG. 11(c). Since the portion is bendable, the connecting body holder 3 can be bent at an appropriate angle to lock the locking protrusion 4e of the lock connecting body 4 in the locking recess 7a of the input section 7.

The input portion 7 of the locking mechanism portion 6 is formed with a funnel-shaped guide portion 7b whose diameter gradually increases toward the front for guiding the locking protrusion 4e of the lock connector 4 to the locking recess 7a.

Thereafter, when the operating force on the release operation section 8 is released, the stopper body 11 returns to the locked position, and the lock coupling body 4 maintains the locked state with the input section 7 by the action of the compression spring 32.

In addition, although the case has been described above in which the coupling operation between the cylinder lock (CY) and the input unit 7 is performed by moving the handle device (H), it is also possible to fix the handle device (H) to the door 5 in advance. It is also possible to move the input section 7 to a predetermined position. In this case as well, the operation of moving the input unit 7 is performed while the lock connector 4 of the cylinder lock (CY) is held in the unlocked position.
