Description

  The present invention relates to a sliding door provided on a window or door portion of a single sliding door or a three-sliding door.

In various sliding doors such as single-sliding doors and three-sliding doors, as a pulling handle for opening and closing the shoji, a digging-type pulling in which a concave portion is formed in the saddle portion of the shoji and a fixed handle type pulling have been used. .
However, when the digging type pull is formed on the indoor surface of the shoji, there is a problem that the concave portion formed in the heel portion is exposed to the room and the design property is lowered. In addition, if the digging type handle is formed on the side surface orthogonal to the indoor surface of the shoji, it becomes difficult to operate with either the left hand or the right hand depending on the direction of the opening, and there is a problem that the operability is lowered.
In addition, the fixed handle type handle is also formed so as to protrude from the shoji ridge to the glass surface, and there is a problem that the design property is lowered.

On the other hand, in a door having a swing opening / closing structure, a retractable door handle device is known in which a handle for opening and closing the door is configured to be able to appear and retract in the door body (see Patent Document 1).
In Patent Document 1, a handle main body that is projected and retracted on the surface of the door body is provided, and along with the operation of projecting and retracting the handle body, the handle main body protrudes and protrudes from the peripheral edge of the door body and is engaged with the engagement recess of the door opening peripheral frame. A locking mechanism is provided in the door body. The lock mechanism includes an expansion / contraction means that expands and contracts when the handle body protrudes and retracts, a slide rod that is connected to the expansion / contraction means, and a door latch that is connected to the tip of the slide rod and engages with the engagement recess. Yes.

In this retractable door handle device, when the handle body is pulled out from the door body, the door latch is inserted into the door body via the slide rod, the engagement between the door latch and the engagement recess is released, and the door body can be opened. it can.
On the other hand, when the handle body is pushed into the door body, the door latch projects from the door body via the slide rod, and engages with the engagement recess to lock the door body. However, since the door latch is slidable with respect to the slide rod by a spring, the door latch protrudes from the door body when the door body is opened and the door latch protrudes from the door body, and the door latch is closed when the door body is closed. Even if the door slides in contact with the frame around the door opening, the door latch is pushed into the latch housing by the guide inclined surface of the door latch so that the door body can be closed.

Japanese Patent Laid-Open No. 5-98853

However, in the retractable door handle device described in Patent Document 1, since the door latch is slidable with respect to the slide rod, even if the handle is pushed into the door body, the door latch is not necessarily engaged in the engagement recess. There was a fear that it was not. For example, if the engaging recess is blocked by some member, the door latch will slide against the slide rod even if it is assumed that the handle is pushed into the door body and the door latch is engaged in the engaging recess. Therefore, there is a possibility that a state where the engagement is not engaged in the engagement concave portion may occur.
For this reason, there is a possibility that the door is locked because the handle is pushed into the door body, and there is a problem that the security performance is not so high.

An object of the present invention is to provide a sliding door that allows a pull handle to appear in and out of a shoji's cage, and can unlock or lock the shoji in conjunction with this in / out operation, and can also improve crime prevention performance. is there.

The sliding door of the present invention is a sliding door provided with a frame and a shoji that is slidably movable in the frame, and the side of the shoji has a side surface on the inner peripheral side of the coffin among the side surfaces orthogonal to the indoor surface of the coffin. and the handle that is provided retractably in the sliding direction of the sliding door from the disposed within stiles, and an interlocking member provided movable forward and backward movement in the longitudinal direction of the stile in conjunction with the infested operation of the handle, the interlocking When the handle is moved in conjunction with the advancing and retreating movement of the member and the handle is pushed into the bag, the lock is engaged with the lock receiving portion formed on the frame, and the handle is pulled out from the bag. In the state, when the lock member that is unlocked from the lock receiving portion formed on the frame and the hook provided with the handle are separated from the frame, the handle is kept pulled out of the hook. , Restricted so that it cannot be pushed into the bag, and the handle is provided In the state in which the heel is in contact with the frame, a movement restricting means is provided to allow the handle to move in and out of the heel, and the interlocking members can be moved forward and backward in the longitudinal direction of the heel inside the heel, respectively. A slide body, a switch, a connecting member, and a lock operating member that are provided and connected in series with each other. The slide body and the handle are connected to each other so as to be interlocked with each other, and interlocked with the forward / backward movement of the lock operating member. The lock member is switched between a locked state and an unlocked state, and the movement restricting means is connected to be interlocked with the lock actuating member, and the slide body is advanced and retracted by operating the switch. The handle is configured to be able to switch between locking and unlocking of the lock member as the handle protrudes and retracts from the bag and the lock actuating member via the connecting member advances and retreats.

According to such a configuration, since unlocking or locking is performed in conjunction with the handle operation, operability can be improved. Furthermore, since the handle is submerged in the bag during locking, the appearance of the sliding door can be simplified and the design can be improved. In addition, since the handle is pulled out from the bag during unlocking, it is easy to open and close the shoji, the influence of the difference in the dominant hand can be reduced, and the operability can be improved.
In addition, since the movement restricting means is provided, the handle cannot be pushed into the bag until the shoji is closed, so that the shoji can be operated stably when opening and closing the shoji.
In addition, when the shoji is closed, that is, when the heel is in contact with the frame, the handle can be pushed in and locked for the first time, so that the lock member does not protrude from the heel before the heel contacts the frame. There is no contact. Therefore, unlike Patent Document 1, it is not necessary to employ a configuration in which the lock member is provided so as to be slidable with respect to the interlocking member and the lock member is released when it is brought into contact with the frame. For this reason, the handle is always pushed into the bag when locked, and always protrudes from the bag when unlocked. For this reason, it can be confirmed whether it is an unlocked state or a locked state by the position of a handle, and crime prevention performance can also be improved.

In the present invention, the locking member is pivotally supported with respect to the collar, and is pivotally supported by the interlocking member at a position eccentric from the pivoting shaft, and interlocked with the advance / retreat drive of the interlocking member. It is preferable to be comprised with the sickle lock rotated in the state accommodated in the inside and the state which protrudes from the inside of a cage | hook, and was engaged with the lock receiving part of the frame.
As a locking member, if it is a shoji that slides in the lateral direction, you may use a dead bolt type locking member that appears on the upper or lower side of the shoji and engages with the upper frame or the lower frame, Since the handle and the lock member are separated from each other, the length of the interlocking member becomes long, and a certain amount of force is required for the opening / closing operation. Become.
On the other hand, if a sickle lock is used as in the present invention, it can be placed near the handle, the interlocking member can be formed compactly, the opening and closing operation can be performed with a relatively small force, and the place where the sickle lock is placed is one place. However, the shoji does not tilt and can be locked in a balanced manner.

  In the present invention, the movement restricting means includes a trigger provided so as to be able to protrude and retract from the frame contact surface of the heel and having a guide pin, an urging means for urging the trigger in a direction protruding from the heel, and the interlocking A guide groove that is formed in a member and in which the guide pin of the trigger is disposed. The guide groove is engaged with the guide pin when the trigger is in a protruded state. And a long groove portion in which the guide pin is arranged and the interlocking member is movable when the trigger is in a state of being pushed into the bag while being in contact with the frame. It is preferable to be configured.

  If such a movement restricting means is provided, the interlocking member can be moved only when the trigger abuts against the frame and enters the bag against the urging force of the urging means. In addition, locking and unlocking operations are possible. Therefore, when the shoji is open and its heel is separated from the frame, the trigger is protruded from the heel by the urging means, and the interlocking member is kept immovable with the handle protruding from the heel. That is, since the movement restricting means can be configured only by a trigger with a guide pin, an urging means such as a spring, and a guide groove formed in the interlocking member, the movement restricting means can be configured with a simple structure and the cost can be reduced. .

Further, in Rukoto have a switch, handle it can protrude the handle from the stile by moving the interlocking member in the switch when being retracted into the stiles. For this reason, there is no need to grasp the handle itself and pull it out from the bag, the handle pull-out operation can be simplified, and the design can be improved. That is, when the handle itself is grasped and pulled out, it is necessary to provide a portion that protrudes from the ridge on the handle, or to be able to grasp the handle by denting a portion of the ridge. For this reason, in order to simplify the pulling-out operation, it is necessary to enlarge the protruding portion and the recessed portion so that the handle can be easily grasped. On the other hand, in the present invention, the handle can be protruded from the heel by moving the interlocking member forward and backward with another switch, so there is no need to grasp and pull the handle portion, and it is necessary to form the protruding portion and the recessed portion. The appearance design can be improved.

In the present invention, a pair of elastic members are provided at positions sandwiching the handle from both sides intersecting the protruding and retracting direction, and a convex portion or a concave portion is formed on the elastic member, and the handle is pushed into the bag. It is preferable that a concave portion or a convex portion that is engaged with the convex portion or the concave portion of the elastic member is formed in the state where the elastic member is protruded from the ridge and the state where it protrudes the most.
According to such a configuration, since the handle is engaged with the pair of elastic members at least at the two positions of being pushed into the bag and the most protruding state, the handle is stably held at the two positions. In addition, the play of the elastic member can be suppressed because the force of the elastic member is applied to the handle.

In the present invention, it is preferable that a lock means is provided for restricting the handle pulled out from the heel so that it cannot be pushed into the heel.
According to such a configuration, even when the heel is in contact with the frame when closing the shoji and the movement restricting means is deregulated, the lock is restricted by the lock means, so that the handle cannot be pushed into the heel. By removing this restriction, the handle can be pushed into the bag. Therefore, the handle is not pushed into the bag while maintaining the momentum when closing the shoji by operating the handle, and it is possible to prevent a finger or the like from being pinched between the handle and the bag. Furthermore, after closing the shoji, the user can remove the restriction of the locking means with the intention of locking, and the shoji can be locked by pushing the handle into the bag. The door is not pushed into the door and the door is locked, and inconveniences such as frequent opening and closing of the door can be felt, and inconveniences such as closing the child outdoors can be prevented.

In this case, the lock means includes a lock member that restricts the forward and backward movement of the interlocking member, and the lock member is provided so as to be engageable with the interlocking member and to be operated from the indoor side. The restriction release portion is formed, and the engagement portion is urged in a direction to engage with the interlocking member and is rotatably supported with respect to the flange. It is preferable that the engagement portion is configured to be disengaged by an operation.
According to such a configuration, since the locking member is biased in the direction in which the engaging portion engages with the interlocking member, the engaging portion automatically becomes the interlocking member in a state where the handle is pulled out from the hook. Engagement is possible, and the movement of the handle can be controlled reliably and easily without the user performing a locking operation. Further, by disengaging the engaging portion by operating the restriction releasing portion and releasing the movement restriction of the handle, the shoji can be locked if the handle is pushed into the bag in this state.

The cushioning material 17 is formed of a material capable of absorbing an impact, such as sponge or soft rubber, for example, so that when the handle 11 is moved in and out, the handle 11, the case body 13, and the exterior body 12 Even if it hits, sound can be prevented.

  In FIG. 12, a plurality of notch grooves 11H are formed on the side surface of the guide portion 11B of the handle 11, and a pair of protrusions 11I are formed at the intersection of the horizontal portion 11C and the contact portion 11D of the handle 11. Yes. Further, a protrusion 12C is formed at a position corresponding to the notch groove 11H in the opening 12A of the exterior body 12, and a pair of recesses 12D is formed at a position corresponding to the protrusion 11I. And in the state which the handle 11 protrudes most from the case body 13, the notch groove 11H of the guide part 11B and the protrusion 12C of the exterior body 12 are engaged, and the pair of protrusions 11I and the recess 12D are engaged. The play of the handle 11 at this position is prevented. As described above, the notch groove 11H and the protrusion 11I of the handle 11 and the protrusion 12C and the recess 12D of the exterior body 12 constitute a backlash preventing means for the handle 11.

According to this embodiment, there are the following effects.
(1) That is, since the unlocking or locking is performed by the sickle lock 22 of the locking device 20 in conjunction with the operation of the handle 11, operability can be improved. Furthermore, since the handle 11 is submerged in the door toe 8A during locking, the appearance of the sliding window 1 can be simplified and the design can be improved. Moreover, since the handle 11 is pulled out from the door toe 8A at the time of unlocking, it becomes easy to open and close the shoji 5 and the influence of the difference between the dominant hand can be reduced and the operability can be improved.

(2) Furthermore, since the movement restricting means constituted by the trigger 24 and the guide groove 23A of the lock actuating member 23 is provided, the handle 11 cannot be pushed into the door toe 8A until the shoji 5A is closed. The handle 11 can be stably operated when opening and closing the shoji 5A.

(3) Further, when the shoji 5A is closed, that is, when the trigger 24 is immersed in the door toe 8A, the handle 11 can be pushed and locked for the first time, so that the sickle lock 22 is inserted before the trigger 24 is inserted into the door toe 8A. Does not protrude from the door toe 8A, and the sickle lock 22 does not contact the vertical frame 4. Therefore, unlike the conventional retractable door handle device, it is not necessary to adopt a configuration in which the lock member is provided so as to be slidable with respect to the interlocking member and the lock member is released when it comes into contact with the frame. For this reason, the handle 11 is always pushed into the door toe 8A when locked, and always protrudes from the door toe 8A when unlocked. For this reason, it can confirm whether it is an unlocked state or a locked state by the position of the handle 11, and a crime prevention performance can also be improved.

(4) Furthermore, since the lock actuating member 23 can be moved only when the trigger 24 comes into contact with the vertical frame 4 and is immersed in the door rod 8A against the urging force of the spring member 24B, the lock 11 It is possible to perform in / out operations and lock / unlock operations. Therefore, when the shoji 5A is open and the door toe 8A is separated from the vertical frame 4, the trigger 24 protrudes from the door toe 8A by the spring member 24B, and the handle 11 protrudes from the door toe 8A. In this state, the lock actuating member 23 is kept immovable. That is, since the movement restricting means can be configured only by the trigger 24 with the guide pin 24A, the spring member 24B, and the guide groove 23A formed in the lock operating member 23, the movement restricting means can be configured with a simple structure, and the cost is also reduced. Can be reduced.

(5) Further, since the sickle lock 22 that rotates in conjunction with the lock actuating member 23 is used in the lock device 20, the sickle lock 22 can be disposed in the vicinity of the handle 11 as compared with the conventional door handle device. Thus, the lock actuating member 23 can be formed compactly, the opening / closing operation can be performed with a relatively small force, and even if the sickle lock 22 is arranged at one place, the shoji 5A is not tilted and can be locked in a balanced manner.

(6) Further, since the switch 15 capable of moving the slide body 14 and the lock actuating member 23 back and forth is provided, the slide body 14 is moved by the switch 15 when the handle 11 is immersed in the door toe 8A. By doing so, the handle 11 is protruded from the heel, and the sickle lock 22 can be removed from the lock receiving portion 4B by sliding the lock operating member 23. For this reason, it is not necessary to grasp the handle 11 itself and pull it out from the door rod 8A, the pull-out operation of the handle 11 can be simplified, and the design can be improved.

(7) Moreover, since the spacer 18 is interposed between the case body 13 and the door end fence 8A, even when the outside air temperature becomes lower than the room temperature and the door end fence 8A is cooled, the pulling device 10 The temperature drop of the handle 11, the exterior body 12, and the case body 13 can be suppressed, and the occurrence of dew condensation in each of these parts can be prevented.

(8) Furthermore, by using the positioning means of the handle 11 as shown in FIG. 8, 9 or 10, the handle 11 is at least in two positions, the state where it is pushed into the door-end rod 8A and the state where it protrudes most. Since the handle 11 is engaged with the leaf spring 16, the handle 11 can be stably held at the two positions, and the force of the leaf spring 16 is applied to the handle 11, so that play can be suppressed.

(9) Further, by providing a cushioning material 17 as shown in FIG. 11 at the contact portion 11D of the handle 11, it is possible to prevent a collision sound with the case body 13 and the exterior body 12 when the handle 11 is operated. Can do.

(10) Furthermore, by using the rattle prevention means of the handle 11 as shown in FIG. 12, it is possible to prevent the handle 11 from rattling in the state where the handle 11 protrudes most from the door end rod 8A.
