Description

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

  It takes a relatively large amount of force in order to overcome the inertia and open the larger and heavy fittings, in particular the sliding doors, than the conventional fittings in the closed state. Locking devices provided with an opening support mechanism are used for such fittings (sliding doors) that require a relatively large force at the beginning of opening. As a lock device with an opening support mechanism, for example, a “lock with opening support mechanism” described in Patent Document 1 is known.

FIG. 11 is a longitudinal sectional view of the conventional sliding door with a lock for opening and closing described in Patent Document 1 as viewed from the front.
In the case 110 mounted on the sliding door 102, the lock with the opening support mechanism is operated to switch the hook bolt 115 engaged with the striker 104 attached to the vertical frame and the hook bolt 115 between the locking position and the locking position. The lock is provided with a thumb-turn shaft 120 integral with the thumb-turn lever, a trigger 117 for restricting the switching of the hook bolt 115 in the unlocked state to the locking position, and an opening support mechanism. A kick lever 142 pivotally supported so as to be able to reciprocate between a standby posture in the case 110 and an operating posture in which a part thereof protrudes out of the case 110, biases movement of the kick lever 142 toward the standby posture. It includes a return spring 146 and an operating handle 145 for switching the kick lever 142 to the operating position against the biasing force of the return spring 146.
The kick lever 142 and the hook bolt 115 are interlockably connected via the link rod 147, and in a state where the fully closed sliding door 102 is forcibly opened by the operating handle 145, the handle operation of the operating handle 145 is performed. In conjunction with this, the hook bolt 115 can be unlocked from the locked state.

However, in the conventional lock with the opening support mechanism described above, the operation part (such as thumb turn lever) for locking and unlocking and the operation handle for operating the opening support mechanism are different, and the operation for opening and opening the window is Although the operation can be performed continuously, the operation for closing and locking the window is complicated, since the operation is independent. Also, the structure is complicated.
Not only does the structure of the case become complicated, but the kick lever and the hook bolt operating mechanism are all housed in one case, and the kick lever is placed at an arbitrary position away from the position of the operation handle. Is difficult, and multiple kick levers can not be arranged. In addition, there is a restriction on the case, and there is a problem that it is difficult to increase the size of each part and to transmit a large torque with the operation lever.

As a result, by rotating the operation handle 20a by, for example, 90 °, unlocking is performed by removing the latch from the hook provided on the opening frame prior to the operation of the kicking roller 64 of the opening support mechanism 60.
The lock device may have any structure as long as it can be locked or unlocked by rotating the operation handle 20a (for example, a lock described in Japanese Utility Model Application Publication No. 59-15584, Japanese Patent Application Laid-Open No. 2006-241748). And the like, and when locking or unlocking by rotating the operating handle 20a, it is not limited to one that directly operates a latch or the like by the handle shaft 22 of the operating handle 20a, but the interlocking bar 50 The locking and unlocking may be interlocked with the vertical movement of the lens.

Next, the opening support mechanism 60 will be described.
FIG. 5A is a perspective view of the opening support mechanism 60, and FIG. 5B is a perspective view of guide pin attachment means 54 for driving the kicking arm 63 of the opening support mechanism 60.
The opening support mechanism 60 generally comprises a mounting base 61 and a kicking arm 63 pivotally attached to the base 61.
The base plate 61 is formed in a substantially L-shaped cross section including an attaching portion 61a for attaching to the vertical rod 2c of the sliding door, and an arm supporting portion 61b supporting the kicking arm bent at a right angle from the attaching portion 61a. .
As shown in FIG. 5A, a kicking arm 63 is pivotally connected to the arm supporting portion 61b by a connecting pin 62 in the vicinity of the upper end thereof, and the kicking arm 63 is kicked out at the free end (rotation end) of the kicking arm 63. A kicking roller 64, which is a means, is rotatably fixed.

Here, the arm support portion 61b is provided with a first guide groove 61b (1) in the vertical direction as shown in the drawing, and the kicking arm 63 has a guide groove portion in the vertical direction in the drawing. A generally H-shaped second guide groove 63a is provided having a groove bent obliquely upward from the upper end of the second guide groove 63a. The longitudinal direction portions of the first and second guide grooves 61b (1), 63a are arranged in alignment as shown.
On the other hand, as shown in FIG. 5B, the guide pin attachment means 54 has a substantially L-shaped cross section, and its attachment surface 54a is fixed to the interlocking bar 50 by an 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.

The guide pin 56 is, as shown in FIG. 5A, both the first guide groove 61b (1) of the arm support portion 61b of the substrate 61 and the second guide groove 63a bent in a substantially V shape of the kicking arm 63. It is inserted in the
In this configuration, when the operation handle 20a is turned to raise the interlocking bar 50 by the operation mechanism 20 from the closed state of the sliding door 2, the guide pin 56 is moved 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 vertical direction groove portion of the second guide groove 63a, the kicking arm 63 is not driven and immobile, but in the meantime, it is not illustrated by the operating handle 20a which rotates. The key is unlocked.

  Next, when the guide pin 56 further ascends with the rotation of the operation handle 20a and reaches the groove portion directed obliquely upward of the second guide groove 63a, the guide pin 56 rising thereafter is a groove directed obliquely upward Push up the part. As a result, the kicking arm 63 pivots around the connection pin 62 to move outward from the longitudinal edge 2c of the sliding door, kick the sliding door longitudinal frame 1c, and push the sliding door 2 in the opening direction.

In the present embodiment, as described above, the key is first unlocked with the rotation of the operation handle 20a, and then the kicking arm 63 is operated. In this case, the delay of the operation from the start of rotation of the operation handle 20a to the start of operation of the kicking arm 63 is an 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 which freely moves 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 °. There is.

Although the opening support mechanism 60 (the kicking arm 63) has been described above as one, the lock device of the present invention is not limited to this.
That is, a plurality of opening support mechanisms 60 can be attached at the top and bottom at predetermined intervals in the vertical rod 2c, and they can be interlocked with one interlocking bar 50. By adopting this configuration, it is possible to simultaneously operate the plurality of opening support mechanisms 60 by one rotation operation of the operation handle 20a. By operating the opening support mechanism 60 at the same time, the sliding door 2 can be pushed out with better balance than when one opening supporting mechanism 60 is provided, and the pushing operation from the fully closed position of the sliding door 2 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 power in the operation mechanism 20 to the opening support mechanism 60. The structure may be plate-like, rod-like, etc. 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 sky hanging prevention mechanism 70 described later can operate. Just do it. Therefore, the interlocking bar in the present invention is used as a generic term of these.
FIG. 6 is a perspective view of the interlocking bar 50 formed in a plate shape as an example.
The lower end side of the interlocking bar 50 is connected to the connection portion 40 b of the slider 40, and the upper end side thereof is connected to the guide pin attachment means 54.

  Further, a notch 55 in the lateral direction is formed in the middle part of the upper and lower ends of the interlocking bar 50, and the notch 55 constitutes a part of the idling prevention mechanism 70 shown in FIG. That is, when the sliding door is opened, the notch 55 engages with the wall 72b (1) (FIGS. 7A and 7B) serving as a stopper of the idling prevention mechanism 70 described later, thereby the upper and lower sides of the interlocking bar 50 The movement is blocked, and the locking device is prevented from emptying when the sliding door is opened.

Next, the detailed structure of the anti-idle mechanism 70 will be described.
FIG. 7A is a cross-sectional view of the anti-idling mechanism 70 (non interlocking means), and FIG. 7B is a side view thereof.
The locking 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, and roughly contacts the sliding door 2 when it is closed. A door contact portion (also referred to as a trigger) 72 having a contact surface 72a and a biasing means for always pressing the door contact portion 72 toward the sliding door vertical frame 1c side, in this case a coil spring 74, accommodates these and It consists of case 75 which has a side wall used as a guide at the time of contact part 72 appearing and retreating.

The door stop portion 72 includes an abutting surface 72a that abuts on the sliding door vertical frame 1c, and a groove 72b (a wall portion 72b (1) described later) which is formed inside the projecting direction of the abutting surface 72a and allows passage of the interlocking bar 50. When the sliding door 2 is separated from the sliding door vertical frame 1c and the door stopper 72 protrudes from the vertical weir 2c, the notches 55 of the interlocking bar 50 (upper and lower wall surfaces 55a (1) , 55a (2)), and has a wall portion 72b (1) serving as a stopper for blocking the vertical movement of the interlocking bar 50.
When the sliding door is fully closed, the contact surface 72a abuts on the sliding door vertical frame 1c or the vertical bone, and squeezes the coil spring 74 to retract the coil spring 74 toward the vertical rod 2c. On the other hand, in the state in which the sliding door is opened, it projects from the vertical weir 2c by the biasing force (elastic force) of the coil spring 74. FIGS. 7A and 7B each show a state in which the door contact portion 72 protrudes due to the biasing force of the coil spring 74.

Here, the width W1 of the groove portion 72b of the door contact portion 72 shown in FIG. 7B is 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 opens by a width (distance) corresponding to the predetermined width W1.
When the sliding door opens by a width corresponding to the width W1, the notch 55 of the interlocking bar 50 abuts on the wall portion 72b (1) of the door stopper 72 to prevent the interlocking bar 50 from moving up and down. Thereafter, even when the operating handle 20a is to be rotated, the interlocking bar 50 is restrained and can not be rotated, so that the locking of the lock device and the operation of the kicking arm 63 are blocked.

  When closing the sliding door, when the sliding door approaches the fully closed position and the contact surface 72a of the door contact portion 72 protruding from the longitudinal rod 2c abuts on the sliding door vertical frame 1c or the vertical bone, the door contact 72 Retreat against the force of In that case, if the retreating width of the door contact portion 72 exceeds the width W2 (preferably formed equal to the width of the interlocking bar 50) of the wall portion 72b (1) of the groove 72b in contact with the interlocking bar 50, The interlocking bar 50 comes out of contact with the door stopper 72, and can freely move up and down in the groove 72b of the door stopper 72. Therefore, in this position, that is, prior to reaching the fully closed position, the locking operation of the sliding door becomes possible.

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 of the sliding door to the unlocking position, and FIGS. 8A to 8D are diagrams showing the operation of the opening support mechanism 60 accompanying the rotation of the operation handle 20a. Further, FIG. 9 is a view showing a contact state between the resin nut 34 (contact portion 34a) and the pressing member 32 (flat surface 32a) which changes corresponding to the operation 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 operating handle 20a is in the upright position as shown, for example. Further, the contact portion 34a of the handle shaft 22 and the flat surface 32a of the pressing member 32 at this time are in contact with each other at flat surfaces (see FIG. 9A).

Here, in order to open the sliding door, first, the operation handle 20a is turned downward from the upright position (in FIG. 8, it is turned counterclockwise).
With the rotation of the operation handle 20a, 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 while pushing the flat surface 32 a of the pressing member 32 up and down against the pressing force from the pressing member 32.

  At the same time, the pivoting piece 37 integrally coupled to the handle shaft 22 pivots. Also, along with that, the guide pin 37 (1) with the collar 37 (2) of the pivoting piece 37 pivots upward, and pushes up the lateral guide groove 40 (1) of the slider 40. The slider 40 is guided by the guide pins 42a and 42b whose upper and lower guide grooves 40a (1) and 40a (2) are attached to the case cover 43 and smoothly ascends. When the slider 40 ascends, the interlocking bar 50 integrally connected to the slider 40 ascends.

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

FIGS. 8B and 9B show the position of the operation handle 20a at this time, 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 the case of FIG. 9A, the flat surface 32a of the pressing member 32 is in contact with the rectangular surface of the contact portion 34a in the vertical direction. That is, the flat surface of the contact portion 34 a and the flat surfaces of the pressing member 32 are in contact with each other in a state where the pressing force of the pressing member 32 is applied, and are maintained in a stable state.

  From this state, when the operation handle 20a is further rotated, the guide pin 56 of the guide pin attachment means 54 connected to the interlocking bar 50 is further raised, and when it reaches a portion inclined obliquely upward of the second guide groove 63a. And abut on the upper wall of the second guide groove 63a which is inclined and push it up. As a result, the kicking arm 63 provided with the second guide groove 63 a pivots upward around the connection 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 guide pin 56 reaches the obliquely upper end of the second guide groove 63a by rotating the operation handle 20a.
FIG. 8C and FIG. 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 the present embodiment, this position is a position rotated less than 120 ° from the beginning.

  Next, the return from the states of FIGS. 8C and 9C to the states of FIGS. 8D and 9D will be described. In this embodiment, this operation is performed automatically. That is, as described above, the contact portion 34a of the cross section square of the resin nut 34 accommodating the handle shaft 22 of the cross section square has the flat surface 32a that contacts the rectangular surface of the contact 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.

  FIG. 9C shows a state in which the operating handle 20a (therefore, the contact portion 34a) is further rotated by about 30 ° from the state of FIG. 9B. In this state, the guide pin 56 of the guide pin attachment means 54 of the interlocking bar 50 is in contact with the upper end portion of the bent portion directed obliquely upward of the second guide groove 63a of the kicking arm 63, and the operation handle 20a (abutment portion 34a) is the maximum rotational position.

In this case, the flat surface of the contact portion 34 a contacts 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. Therefore, when the gripped operating handle 20a is released, the operating handle 20a is pivoted in the direction opposite to the pivoting, and the state of the contact portion 34a and FIG. 9D (FIG. 9B) is obtained. That is, the resin nut 34 is automatically rotated to return to the state of FIG. 8B, and the interlocking bar 50 is lowered accordingly, and the guide pin 56 of the guide pin attachment means 54 is the second of the kicking arm 63. The bent portion directed obliquely upward of the guide groove 63a is lowered, and the kicking roller 64 of the opening support mechanism 60 returns to the standby position in the longitudinal ridge 2c of the sliding door.
Further, as apparent from the above description, the rotation of the operation handle 20a is a click motion for each rotation.

Next, when the above-described series of sliding door unlocking and kicking operations are completed, the anti-idle mechanism 70 is activated to prevent the non-idling of the lock. Next, this point will be described.
As described above, the anti-idling 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 view showing the operation procedure of the idling prevention mechanism (non interlocking means), FIG. 10A at the time of locking, FIG. 10B at unlocking, FIG. 10C at kicking out, and FIG. The blanking prevention mechanism 70 is shown respectively.

That is, in the state of FIG. 10A, the vertical hook 2c of the sliding door is in contact with the frame longitudinal frame, and in this state, the door contact portion 72 resists the biasing force of the coil spring 74. It is in contact with the bone. Therefore, the door stop portion 72 is stopped at 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 ascends, and the notch 55 thereof passes through the groove 72b of the door stopper 72. At this stage, the lock is unlocked but the opening support mechanism 60 has not been activated yet. Therefore, the vertical hook 2c of the sliding door 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 stopper 72 as in FIG. 10A.

The state of FIG. 10C shows the 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, a reaction force against the coil spring 74 from the sliding door vertical frame 1c against the door contact portion 72 does not act. Therefore, the door stopper 72 tries to project outward from the longitudinal ridge 2c of the sliding door, but the lower part of the notch 55 of the interlocking bar 50 is in contact with the lower side wall of the groove 72b of the door stopper 72. Because of the contact, the protrusion of the door stopper 72 is blocked.

  The state of FIG. 10D shows a state when the interlocking bar 50 is lowered from the state of FIG. 10C in accordance with which the kicking roller 64 which has kicked out has automatically returned to the original standby position. That is, when the notch 55 of the interlocking bar 50 matches the position of the groove 72b during this lowering, the interlocking bar 50 is unrestrained at that moment, so the door contact 72 is biased by the biasing force of the coil spring 74. Through the notch 55 of the interlocking bar 50, it flies out of the vertical weir.

When the door stopper 72 jumps out from the vertical rod at one end, the upper and lower end portions 55a and 55b of the notch 55 of the interlocking bar 50 are in a positional relationship in which the door stopper 72 is sandwiched therebetween. Therefore, if it is attempted to raise the interlocking bar 50, the wall 72b (1) of the door stopper 72 moves to the upper end 55a of the interlocking bar 50, and if it is going to lower the interlocking bar 50. The wall surface abuts on the lower end 55 b of the interlocking bar 50. Therefore, the movement of the interlocking bar 50 becomes impossible.
Therefore, it is possible to prevent the locking device from being idled.

In the above, the operation from the unlocking of the lock to the kicking of the sliding door in the key device according to the embodiment of the present invention has been described. Conversely, even when the sliding door in the open state is in contact with the sliding door vertical frame After contacting the vertical frame, the operating handle is turned clockwise in FIG. 8 from the state of FIG. 8B to the state of FIG. 8A, so that a latch connected to the handle shaft is provided on the sliding door vertical frame Engage the department to complete the lock.
In that case, in the conventional lock, since the engagement of the lock is performed by the rotation of the thumb turn lever, a relatively large moment like the operation handle can not be utilized. In addition, if an operation handle is provided instead of the thumb turn lever, the number of operation handles is two, which is not only difficult to arrange, but also unsightly in design.

Further, according to the present embodiment, since the operations of locking or unlocking and kicking can be performed in order and all can be performed with one operation handle, the continuity of the operation can be secured. In addition, it is possible to enlarge the operating handle itself to utilize a relatively large moment by the operating handle.
Therefore, it is possible to lock strongly as compared with the conventional lock mechanism, and it is possible to lock the fitting while crushing the air tight material by interposing the air tight material.
Further, since the locking of the lock device can be prevented automatically by the simple configuration by the abutment of the door contact portion and the interlocking bar, the operation of the key device can be simplified as a whole.
