Description

  The present invention relates to a locking device with an opening support mechanism applied to a joinery, and a sliding door provided with the locking device with an opening support mechanism.

  A relatively large force is required to overcome the inertial force and open the heavier and heavier fittings than ordinary fittings that are closed. For such a joinery (sliding door) that requires a relatively large force in the initial stage of opening, a lock device having an opening support mechanism is used. As this locking device with an opening support mechanism, for example, a “sickle lock with an opening support mechanism” described in Patent Document 1 is known.

FIG. 11 is a longitudinal sectional view as seen from the front of the sliding door of the conventional sickle lock with an opening support mechanism described in Patent Document 1. FIG.
In the sickle lock with the opening support mechanism, the case 110 attached to the sliding door 102 is operated to switch the hook bolt 115 to be engaged with and disengaged from the striker 104 attached to the vertical frame, and the hook bolt 115 between the locking posture and the unlocking posture. A sickle lock provided with a thumb turn shaft 120 integrated with a thumb turn lever, a trigger 117 for restricting the unlocked hook bolt 115 from switching to a locked posture, and an opening support mechanism. A kick lever 142 that is pivotally supported so as to be reciprocally movable between a standby posture in the case 110 and an operating posture in which a part of the case 110 protrudes out of the case 110, and the kick lever 142 is moved and biased toward the standby posture. It includes a return spring 146 and an operation handle 145 that switches the kick lever 142 to the operating posture against the urging force of the return spring 146.
The kick lever 142 and the hook bolt 115 are connected to each other via a link rod 147 so that the operation handle 145 can be operated when the fully closed sliding door 102 is forcibly opened by the operation handle 145. In conjunction with this, the hook bolt 115 can be unlocked from the locked state.

However, the conventional sickle lock with an opening support mechanism has a lock / unlock operation part (such as a thumb turn lever) and an operation handle for operating the opening support mechanism. Although it can be performed continuously, the operation of closing and locking the window is independent, so the operation is complicated. The structure is also complicated.
The kick lever and hook bolt operating mechanism are all housed in a single case, which not only complicates the structure of the case, but also places the kick lever at an arbitrary position away from its operating handle. It is difficult to place multiple kick levers. In addition, there is a problem that requires a solution, for example, it is difficult to transmit a large torque with an operation lever by increasing the size of each component due to restrictions on the case.

Thus, the operation handle 20a is rotated by 90 °, for example, and unlocking is performed by removing the latch from the latch provided on the opening frame before the kicking roller 64 of the opening support mechanism 60 operates.
The lock device may be of any structure as long as it can be locked or unlocked by rotating the operation handle 20a (for example, locks described in Japanese Utility Model Publication Nos. 59-15584 and 2006-241748). Here, when locking or unlocking by rotating the operation handle 20a, the interlocking bar 50 is not limited to the one that directly operates the latch with the handle shaft 22 of the operation handle 20a. It may be locked and unlocked in conjunction with the up and down movement of the.

Next, the opening support mechanism 60 will be described.
5A is a perspective view of the opening support mechanism 60, and FIG. 5B is a perspective view of the guide pin mounting means 54 that drives the kicking arm 63 of the opening support mechanism 60. FIG.
The opening support mechanism 60 is generally composed of a mounting substrate 61 and a kicking arm 63 pivotally attached to the substrate 61.
The substrate 61 is formed in a substantially L-shaped cross section including an attachment portion 61a for attachment to the vertical fence 2c of the sliding door and an arm support portion 61b for supporting a kicking arm bent at a right angle from the attachment portion 61a. .
As shown in FIG. 5A, a kicking arm 63 is pivotally attached to the arm support portion 61b by a connecting pin 62 in the vicinity of its upper end, and the kicking arm 63 kicks out at the free end (rotating end). A kicking roller 64 as a means is fixed rotatably.

Here, the arm support portion 61b is provided with a first guide groove 61b (1) in the vertical direction as shown in the figure, and the kicking arm 63 has a vertical guide groove portion in the drawing. A second guide groove 63a having a substantially hemispherical shape as a whole having a groove bent obliquely upward from the upper end thereof is provided. The longitudinal portions of the first and second guide grooves 61b (1) and 63a are arranged in alignment with each other as shown.
On the other hand, as shown in FIG. 5B, the guide pin mounting means 54 has a substantially L-shaped cross section, and its mounting surface 54a is fixed to the interlocking bar 50 by appropriate means such as screwing. A guide pin 56 is erected on a guide pin mounting surface 54 b bent at a right angle from the mounting surface 54 a of the guide pin mounting means 54.

As shown in FIG. 5A, the guide pin 56 includes both the first guide groove 61 b (1) of the arm support portion 61 b of the substrate 61 and the second guide groove 63 a that is bent in a substantially square shape of the kicking arm 63. Is inserted.
In this configuration, when the operating handle 20a is rotated from the closed state of the sliding door 2 and the interlocking bar 50 is raised by the operating mechanism 20, the guide pin 56 is connected to the first guide groove 61b (1) and the second guide groove. Ascend in the longitudinal groove portion of 63a. Here, while the guide pin 56 ascends in the longitudinal groove portion of the second guide groove 63a, the kicking arm 63 is not driven and does not move, but during this time, it is not shown by the rotating operation handle 20a. The key is unlocked.

  Next, as the operation handle 20a is rotated, the guide pin 56 further rises to reach the obliquely upward groove portion of the second guide groove 63a. Thereafter, the ascending guide pin 56 becomes the obliquely upward groove. Push up the part. Thereby, the kicking arm 63 rotates around the connecting pin 62 and comes out from the vertical rod 2c of the sliding door, kicks the sliding door vertical frame 1c and pushes the sliding door 2 in the opening direction.

In this embodiment, as described above, as the operation handle 20a rotates, the key is first unlocked, and then the kicking arm 63 is operated. In this case, the operation delay from the start of the rotation of the operation handle 20a to the start of the operation of the kicking arm 63 is caused by the idle movement of the guide pin 56 in which the guide pin 56 moves in the longitudinal groove portion of the second guide groove 63a. Realized by. Therefore, the guide pin 56 that moves idle in the longitudinal groove portion of the second guide groove 63a constitutes the operation delay means of the present invention.
In the present embodiment, the length of the longitudinal groove portion of the second guide groove 63a is set to the sliding length of the slider 40 and the interlocking bar 50 when the operation handle 20a is rotated by 90 °. Yes.

In the above description, the opening support mechanism 60 (the kicking arm 63) is described as being one, but the locking device of the present invention is not limited to this.
That is, it is also possible to adopt a configuration in which a plurality of opening support mechanisms 60 are vertically attached at predetermined intervals in the vertical rod 2c and are linked to one interlocking bar 50. By adopting this configuration, a plurality of opening support mechanisms 60 can be simultaneously operated by one rotation operation of the operation handle 20a. By simultaneously operating the opening support mechanism 60, the sliding door 2 can be pushed out in a better balance than when one opening support mechanism 60 is provided, and the pushing operation of the sliding door 2 from the fully closed position can be performed smoothly. .

Next, the interlocking bar 50 will be described.
The interlocking bar 50 is configured as an interlocking member that transmits the turning force in the operation mechanism 20 to the opening support mechanism 60. The structure may be any shape such as a plate shape or a rod shape. In short, the vertical movement based on the rotation converted by the operation mechanism 20 can be transmitted to the opening support mechanism 60, and the emptying prevention mechanism 70 described later can be operated. That's fine. Therefore, the interlocking bar in the present invention is used as a generic term for these.
FIG. 6 is a perspective view of the interlocking bar 50 formed in a plate shape as an example.
The interlocking bar 50 has a lower end connected to the connecting portion 40 b of the slider 40 and an upper end connected to the guide pin mounting means 54.

  Further, a notch 55 in the horizontal direction is formed at the middle part of the upper and lower ends of the interlocking bar 50, and the notch 55 constitutes a part of the emptying prevention mechanism 70 shown in FIG. That is, when the sliding door is opened, the notch portion 55 engages with a wall portion 72b (1) (FIGS. 7A and 7B) serving as a stopper of an empty hanging prevention mechanism 70, which will be described later. The movement is prevented, and the lock device is prevented from hanging when the sliding door is opened.

Next, the detailed structure of the emptying prevention mechanism 70 will be described.
FIG. 7A is a sectional view of the emptying prevention mechanism 70 (non-interlocking means), and FIG. 7B is a side view thereof.
The anti-hanging mechanism 70 is provided at an appropriate position between the operation mechanism 20 and the opening support mechanism 60 along the interlocking bar 50 of the vertical shaft 2c, and is roughly abutting when the sliding door 2 is closed. A door stop portion (also referred to as a trigger) 72 having a contact surface 72a, and an urging means that constantly presses and urges the door stop portion 72 toward the sliding door vertical frame 1c side, in this case, a coil spring 74, and housing these, It consists of a case 75 having a side wall that serves as a guide when the contact portion 72 appears and disappears.

The door stop portion 72 includes a contact surface 72a that contacts the sliding door vertical frame 1c, and a groove portion 72b (a wall portion 72b (1) described later) that is formed on the inner side in the protruding direction of the contact surface 72a and allows the interlocking bar 50 to pass therethrough. When the sliding door 2 is separated from the sliding door vertical frame 1c and the door contact portion 72 protrudes from the vertical rod 2c, the notch portion 55 (the upper and lower wall surfaces 55a (1) of the interlocking bar 50 is preferable. , 55a (2)) and a wall portion 72b (1) serving as a stopper for preventing the interlocking bar 50 from moving up and down.
When the sliding door is fully closed, the contact surface 72a contacts the sliding door vertical frame 1c or the vertical bone, compresses the coil spring 74, and retracts to the vertical rod 2c side. On the other hand, when the sliding door is opened, the coil spring 74 protrudes from the vertical rod 2c by the urging force (elastic force). 7A and 7B show a state in which the door stop portion 72 protrudes due to the urging force of the coil spring 74. FIG.

Here, the width W1 of the groove 72b of the door stop 72 shown in FIG. 7B is configured to be wider than the width W2 of the interlocking bar 50. Therefore, the interlocking bar 50 can freely move up and down while the fully closed sliding door 2 is opened by a width (distance) corresponding to the predetermined width W1.
When the sliding door is opened by a width corresponding to the width W1, the cutout portion 55 of the interlocking bar 50 and the wall portion 72b (1) of the door stop portion 72 come into contact with each other to prevent the interlocking bar 50 from moving up and down. Thereafter, even if the operation handle 20a is to be rotated, the interlocking bar 50 is constrained so that the operation handle 20a cannot be rotated, so that the locking device is hung and the kicking arm 63 is prevented from operating.

  When the sliding door is closed, when the sliding door approaches the fully closed position and the contact surface 72a of the door contact portion 72 protruding from the vertical rod 2c contacts the sliding door vertical frame 1c or the vertical bone, the door contact portion 72 is turned into the coil spring 74. Retreat against the force of the. In that case, when the retreat width of the door stop portion 72 exceeds the width W2 of the wall portion 72b (1) of the groove portion 72b in contact with the interlocking bar 50 (preferably formed equal to the width of the interlocking bar 50), The interlocking bar 50 comes out of contact with the door stop 72, and can freely move up and down in the groove 72b of the door stop 72. Therefore, the sliding door can be locked in this position, that is, prior to reaching the fully closed position.

Next, the overall operation of the key device according to the embodiment of the present invention described above will be described with reference to the drawings.
FIG. 8 is a front view showing the entire structure from the locking position to the unlocking position of the sliding door, and FIGS. 8A to 8D are views showing the operation of the opening support mechanism 60 accompanying the rotation of the operation handle 20a. FIG. 9 is a diagram showing a contact state between the resin nut 34 (contact portion 34a) and the pressing member 32 (flat surface 32a) that change in accordance with the operations of FIGS. 8A to 8D.

  That is, FIG. 8A shows a state in which the sliding door is closed and locked by the lock device, and the operation handle 20a is in an upright position as shown in the figure, for example. Further, the contact portion 34a of the handle shaft 22 and the flat surface 32a of the pressing member 32 at that time are in contact with each other between the flat surfaces (see FIG. 9A).

Here, in order to open the sliding door, first, the operation handle 20a is rotated downward from the upright position (in FIG. 8, it is rotated counterclockwise).
As the operation handle 20a rotates, the handle shaft 22 shown in FIG. 9A and the resin nut 34 fitted on the handle shaft 22 rotate. At that time, the resin nut 34 rotates against the pressing force from the pressing member 32 while pushing the flat surface 32a of the pressing member 32 up and down.

  At the same time, the rotating piece 37 integrally connected to the handle shaft 22 rotates. Along with this, the guide pin 37 (1) with the collar 37 (2) of the rotating piece 37 rotates upward and pushes up the lateral guide groove 40 (1) of the slider 40. The slider 40 ascends smoothly as its upper and lower guide grooves 40 a (1) and 40 a (2) are guided by guide pins 42 a and 42 b attached to the case cover 43. When the slider 40 is raised, the interlocking bar 50 integrally connected to the slider 40 is raised.

When the interlocking bar 50 is raised, the guide pins 56 of the guide pin attaching means 54 attached to the upper part of the interlocking bar 50 are raised in the first guide groove 61b (1) and the second guide groove 63a. At the same time, the latch (not shown) is pulled up from the latching portion of the opening frame in conjunction with the rotation of the handle shaft 22 and unlocked.
When the interlocking bar 50 is further lifted with the rotation of the operation handle 20a, the guide pin 56 of the guide pin mounting means 54 of the interlocking bar 50 is a bent portion that extends obliquely upward of the second guide groove 63a of the kicking arm 63. To reach.

8B and 9B show the position of the operation handle 20a and the positional relationship between the resin nut 34 (contact portion 34a) and the pressing member 32 (flat surface 32a).
That is, the operation handle 20a and the resin nut 34 are both turned 90 ° from the start of operation.
In this state, as in FIG. 9A, the flat surface 32a of the pressing member 32 is in contact with the rectangular surface of the contact portion 34a from above and below. That is, the flat surface of the contact portion 34a and the flat surface of the pressing member 32 are in contact with each other while the pressing force of the pressing member 32 is applied, and are maintained in a stable state.

  When the operation handle 20a is further rotated from this state, the guide pin 56 of the guide pin mounting means 54 connected to the interlocking bar 50 further rises and reaches a portion inclined obliquely upward of the second guide groove 63a. Then, it comes into contact with the upper wall of the inclined second guide groove 63a and pushes it up. As a result, the kicking arm 63 provided with the second guide groove 63 a rotates upward around the connecting pin 62.

Along with this rotation, the kicking roller 64 pivotally attached to the free end (rotating end) of the kicking arm 63 pushes the sliding door vertical frame and pulls the sliding door away from the vertical frame (that is, kicks out). The kicking of the sliding door of the kicking roller 64 is continued until the operation handle 20a is rotated and the guide pin 56 reaches the obliquely upper end of the second guide groove 63a.
8C and 9C show the position of the operation handle 20 at this time and the positional relationship between the resin nut 34 (contact portion 34a) and the pressing member 32 (flat surface 32a).
In this embodiment, this position is a position rotated by less than 120 ° from the beginning.

  Next, the return from the state of FIGS. 8C and 9C to the state of FIGS. 8D and 9D will be described. In this embodiment, this operation is performed automatically. That is, as already described, the abutting portion 34a having a rectangular section of the resin nut 34 that accommodates the handle shaft 22 having a rectangular section has a flat surface 32a that contacts the rectangular surface of the abutting portion 34a from above and below. The pressing member 32 is urged from above and below by the coil spring 33 and is in contact therewith.

  FIG. 9C shows a state in which the operation handle 20a (and hence the contact portion 34a) is further rotated by about 30 ° from the state of FIG. 9B. This state is a state in which the guide pin 56 of the guide pin mounting means 54 of the interlocking bar 50 is in contact with the upper end portion of the bent portion of the kicking arm 63 that extends obliquely upward of the second guide groove 63a. It is the maximum rotation position of 20a (contact part 34a).

In this case, the flat surface of the contact portion 34 a is in contact with the flat surface 32 a of the pressing member 32 at an angle of about 30 °. Therefore, the positional relationship between the two is unstable, and a moment in the reverse rotation direction acts on the contact portion 34a. Accordingly, when the grasped operation handle 20a is released, the operation handle 20a is rotated in the direction opposite to the rotation, so that the contact portion 34a and the state shown in FIG. 9D (FIG. 9B) are obtained. That is, the resin nut 34 automatically rotates and returns to the state shown in FIG. 8B, and the interlocking bar 50 is lowered accordingly, and the guide pin 56 of the guide pin mounting means 54 is moved to the second position of the kick arm 63. The bent portion of the guide groove 63a that is inclined upward is lowered, and the kicking roller 64 of the opening support mechanism 60 returns to the standby position in the vertical rod 2c of the sliding door.
As is clear from the above description, the rotation of the operation handle 20a is a click motion for each rotation.

Next, at the stage where the above series of unlocking and kicking operations of the sliding door is completed, the emptying prevention mechanism 70 is activated to prevent the lock from being lost. Next, this point will be described.
As already described, the emptying prevention mechanism 70 is provided at an appropriate position between the operation mechanism 20 and the opening support mechanism 60 along the interlocking bar 50 of the vertical rod 2c.
FIG. 10 is a diagram showing an operation procedure of the emptying prevention mechanism (non-interlocking means). FIG. 10A is when locking, FIG. 10B is when unlocking, FIG. 10C is when kicking out, and FIG. Each of the emptying prevention mechanisms 70 is shown.

That is, in the state of FIG. 10A, the sliding rod 2c and the frame vertical frame are in contact with each other. In this state, the door contact portion 72 resists the biasing force of the coil spring 74 and the sliding door vertical frame 1c or vertical frame. It touches the bone. Therefore, the door stop portion 72 is stopped on the vertical rod 2 c side, and the interlocking bar 50 can freely move in the groove portion 72 b of the door stop portion 72.
In the state of FIG. 10B, the interlocking bar 50 is raised, and the notch 55 passes through the groove 72 b of the door stop 72. At this stage, the lock is unlocked, but the opening support mechanism 60 has not been operated yet. Therefore, the sliding door vertical rod 2c and the sliding door vertical frame 1c are in contact with each other, and the interlocking bar 50 can freely move in the groove 72b of the door stop 72 as in FIG. 10A.

The state of FIG. 10C shows a state where the interlocking bar 50 has reached the highest position.
In this state, since the sliding door is separated from the sliding door vertical frame 1c, the resistance against the coil spring 74 from the sliding door vertical frame 1c against the door contact portion 72 does not act. Therefore, the door stop portion 72 tends to protrude outward from the vertical rod 2c of the sliding door, but the lower portion of the cutout portion 55 of the interlocking bar 50 is in contact with the lower side wall portion of the groove portion 72b of the door stop portion 72. Since they are in contact with each other, the protrusion of the door stop 72 is prevented.

  The state of FIG. 10D shows a state when the kicking roller 64 once kicked is automatically returned to the original standby position, and accordingly, the interlocking bar 50 is lowered from the state of FIG. 10C. That is, when the notch 55 of the interlocking bar 50 matches the position of the groove 72b during the lowering, the interlocking of the interlocking bar 50 is released at that moment. It jumps out of the vertical shaft through the notch 55 of the interlocking bar 50.

When the door stop portion 72 jumps out from the vertical gutter at one end, the upper and lower end portions 55a and 55b of the notch portion 55 of the interlocking bar 50 are in a positional relationship that sandwiches the upper and lower portions of the door stop portion 72. Therefore, if the interlocking bar 50 is to be raised, the wall 72b (1) of the door stop 72 will be at the upper end 55a of the interlocking bar 50, and if the interlocking bar 50 is to be lowered, it will be below the door stop 72. The wall surface comes into contact with the lower end portion 55 b of the interlocking bar 50. Therefore, the movement of the interlocking bar 50 becomes impossible.
Therefore, it is possible to prevent the lock device from being hung.

The operation from the unlocking of the lock to the kicking out of the sliding door in the key device according to the embodiment of the present invention has been described above. Conversely, even when the sliding door in the open state is in contact with the sliding door vertical frame, the sliding door is temporarily moved. After contacting the vertical frame, the operating handle is rotated clockwise in FIG. 8 from the state of FIG. 8B to the state of FIG. 8A, so that the latch connected to the handle shaft is provided on the vertical frame of the sliding door. Engage with the part to complete the lock.
In that case, in the conventional sickle lock, since the lock is engaged by rotating the thumb turn lever, a relatively large moment such as that of the operation handle cannot be used. If an operation handle is provided in place of the thumb turn lever, the number of operation handles is two, so that it is difficult to arrange and it is difficult to design.

In addition, according to the present embodiment, the operations of locking or unlocking and kicking can be performed in order and all can be performed with a single operation handle, so that continuity of operation can be ensured. In addition, the operation handle itself can be enlarged to use a relatively large moment by the operation handle.
Therefore, it is possible to lock more strongly than the conventional locking mechanism, and it is possible to lock the joinery while crushing the airtight material with the airtight material interposed.
Further, since the lock device can be prevented from being hung up automatically by a simple configuration by the contact of the door stop portion and the interlocking bar, the operation of the key device can be simplified as a whole.
