Description

  The present invention relates to an auxiliary lock device for a sliding door, which can improve a crime prevention function by being attached to an indoor side surface of the sliding door.

For example, in a sliding door device made of an aluminum sash in a window portion of a house, a balcony or the like, a crescent lock is widely adopted as a final lock for preventing outsiders from entering the room.
However, it is known that an outsider can invade relatively easily only by locking the crescent lock only by breaking only the glass-corresponding portion of the outdoor sliding door and unlocking the crescent lock.

Therefore, for example, as shown in FIG. 4, the sliding door provided with the mounting substrate 5 that can be attached to the indoor side surface of the glass of the outdoor sliding door 2 and the lock member 6 that is provided on the mounting substrate 5 so as to be swingable up and down. The auxiliary locking device 1 has already been developed.
In this case, the lock member 6 is made of a plate member pivotally attached to the mounting substrate 5 so as to be swingable up and down around the horizontal axis, and is unlocked from the traveling path of the indoor sliding door 3 (see FIG. 5A). State) and a lock posture (state shown in FIGS. 5B and 5C) protruding into the traveling path of the indoor sliding door 3 are freely switchable.

And according to this conventional auxiliary | assistant lock device 1, when the said lock device 1 is affixed on the corner of the outdoor sliding door 2, as shown to FIG. In addition to locking, the sliding doors 2 and 3 in the closed state can be supplementarily locked. Further, as shown in FIG. 5 (c), when the lock device 1 is attached to the center of the outdoor sliding door 2, the sliding doors 2, 3 with the indoor sliding door 3 opened halfway for ventilation. Can be locked.
Utility Model Registration No. 3054429

In the conventional auxiliary lock device 1, a plate-like magnet that attracts the other to one of the lock member 6 or the mounting substrate 5 is attached, and the lock member 6 is always held in an unlocked posture by this magnet.
Therefore, when the lock member 6 is swung to the lock posture side in order to lock the sliding doors 2 and 3, the user needs to swing the lock member 6 to the indoor side with a force larger than the magnetic force of the magnet. In addition, there is a drawback that the operation of bringing the lock member 6 into the locked posture is complicated.

In particular, in the above-described conventional auxiliary lock device 1, since the lock member 6 is held in the unlocked posture by attracting the lock member 6 to the mounting substrate 5 with a magnetic force, the lock member 6 is frozen in the winter, for example. In this case, it may be very difficult to swing the lock member 6 toward the lock posture.
Therefore, an object of the present invention is to improve the operability of the auxiliary lock device for the sliding door by allowing the lock member in the unlocked position to be easily switched to the locked position.

In order to achieve the above object, the present invention employs the following means.
That is, according to the present invention, in the auxiliary lock device for the sliding door described above, the urging member that constantly urges the lock member toward the lock posture side, and the lock member is held in the unlocked posture against the urging member. A holding member and an operation member for releasing the holding by the holding member are provided.

According to the present invention, the urging member constantly urges the lock member toward the lock posture, and the holding member holds the lock member in the unlocked posture against the urging member. The holding by is released by the operation member. Therefore, when the operation member is operated to release the holding by the holding member, the lock member swings to the lock posture side by the urging force of the urging member, and the lock member can be automatically set to the lock posture.
Therefore, the lock member in the unlocked position can be easily switched to the locked position as compared with the conventional case where the lock member attracted to the mounting substrate by the magnetic force is rocked indoors against the magnetic force. Can do.

In the present invention, the position where the operation member is provided is not particularly limited, but the operation member is preferably disposed on the indoor side surface of the mounting board.
In this case, the presence of the operation member can be reliably recognized from the indoor side, and the operation member can be easily operated with fingers, so that the operability when the lock member is in the locked posture can be further improved.

In the present invention, as a specific configuration of the holding member, while being urged toward the lock member, the holding member is movably accommodated inside the mounting substrate, and with the approach or separation from the lock member. A thing provided with the latching claw for unlocking which engages / disengages with the lock member of an unlocking posture can be adopted.
In this case, the holding member is urged toward the lock member (in the direction of arrow A in FIG. 2), and the latching pawl for unlocking is always held at a position where it engages with the lock member. When the holding member is moved away from the lock member, the latching claw is detached from the lock member, and the lock member swings to the lock posture side by the biasing force of the biasing member.

By the way, the above-described conventional auxiliary lock device (FIG. 4) does not have a function of holding the lock member in the locked posture in the posture.
Therefore, as in the case of a normal crescent lock without a lock holding function, if an intruder such as a thief breaks only the part corresponding to the auxiliary lock device of the glass of the outdoor sliding door, There is a risk that the auxiliary locking device can be easily released simply by swinging the member upward and returning it to the unlocked posture.

Therefore, in the present invention, the holding member further moves into and out of the rocking path of the lock member as it approaches or separates from the lock member, and the lock member is unlocked by moving into and out of the rocking path. It is preferable that a locking claw for holding the lock that restricts or releases the swing to the locked posture is provided.
In this case, since the holding claw is provided on the holding member urged toward the lock member, the holding member is moved away from the lock member by the operation member with respect to the lock member in the lock posture. The lock member in the locked posture cannot be returned to the unlocked posture unless the latching claw is moved out of the rocking path of the lock member.

  Therefore, even if an intruder breaks only the part corresponding to the glass auxiliary lock device of the outdoor sliding door and puts his hand indoors, the lock member can not be in the unlocked posture unless he notices the presence of the operation member, For this reason, it is possible to prevent the auxiliary lock device from being easily unlocked simply by returning the lock member to the unlocked posture.

Further, in the present invention, a pair of the lock member and the operation member are provided for one mounting board, and these members are arranged so as to be in a point-symmetric state with respect to the center portion of the mounting board. It is preferable.
In this case, even if the mounting substrate of the auxiliary lock device is turned upside down, the auxiliary lock device has exactly the same function. For this reason, the user can attach the auxiliary lock device to the outdoor sliding door without worrying about the vertical direction, and the attachment work of the auxiliary lock device is facilitated in this respect.

  As described above, according to the present invention, the lock member in the unlocked posture can be easily switched to the locked posture, so that the operability of the auxiliary lock device for the sliding door is improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

As shown in the figure, this sliding door device is composed of an outdoor sliding door 2 and an indoor sliding door 3 that are slidably fitted in a sash frame (not shown) so as to be slidable with each other, and these sliding doors 2 and 3. A crescent lock (not shown) for final fastening is provided, and a plate-like transparent or translucent glass 4 is fitted in the frame of the sliding doors 2 and 3.

On the other hand, the auxiliary lock device 1 of the present embodiment includes a mounting board 5 that can be attached to the indoor side surface of the glass 4 of the outdoor sliding door 2 and a pair of locking members 6 that are provided on the mounting board 5 so as to be swingable up and down. ing.
These locking members 6 are arranged at positions separated from each other in the width direction, and are unlocked from the traveling path of the indoor sliding door 3 (the posture of the locking member 6 on the right side in FIG. 1), and traveled by the indoor sliding door 3. It is possible to switch to a locking posture protruding in the path (the posture of the lock member 6 on the left side in FIG. 1).

As shown in FIG. 2, the mounting substrate 5 is made of an aluminum alloy box that is flat and has four hollow corners chamfered in a rounded shape, and an adhesive adhesive or the like is formed on the back side of the mounting substrate 5. An adhesive layer (not shown) is provided.
If the warning sign “Security crime prevention lock installation” is written on this adhesive layer, and the warning sign is made visible through the glass 4 from the outside, the intrusion of outsiders such as thieves can be controlled psychologically. can do. Note that this warning display may be any display that reminds the user that some kind of security measures have been taken for the sliding door device, and various displays such as “Police stop” and “Security system installed” should be adopted. Can do.

A storage recess 7 for the lock member 6 is formed on the upper side, the right corner, and the lower side of the mounting substrate 5. A horizontal pivot shaft 8 is installed on the outer edge of the storage recess 7, and the lock shaft 6 can swing up and down by penetrating the pivot shaft 8 through the base end of the lock member 6. It is pivotally attached to the mounting substrate 5.
As shown in FIG. 3, when the lock member 6 is in the unlocked position, almost the entire lock member 6 is stored in the storage recess 7, and the surface of the lock member 6 is substantially flush with the surface of the mounting substrate 5. become. Further, the thickness T (see FIG. 3) of the mounting substrate 5 is set to be smaller than the gap E (see FIG. 1) between the glass 4 of the outdoor sliding door 2 and the vertical frame 3A of the indoor sliding door 3. Yes.

Each of the pair of lock members 6 is made of a substantially rectangular stainless steel plate. Of the pair of lock members 6, the upper first lock member 6 </ b> A is unlocked when the lock member 6 </ b> A swings downward and is entirely stored in the storage recess 7. The lock posture swings upward by the angle and protrudes perpendicularly to the mounting substrate 5.
On the other hand, the lower second lock member 6B is unlocked when the lock member 6B swings upward and is entirely stored in the storage recess 7, and swings downward by 90 degrees from this posture. Thus, the locking posture is such that the mounting substrate 5 protrudes perpendicularly.

A winding spring 9 that functions as a biasing member that constantly biases the lock member 6 toward the lock posture side is wound around the pivot shaft 8, and a rocking force of the lock member 6 is wound around the base end edge of the lock member 6. A restricting piece 10 for restricting the moving angle to approximately 90 degrees is formed.
For this reason, the lock member 6 biased toward the lock posture by the winding spring 10 is a lock in which the lock member 6 protrudes perpendicularly to the mounting substrate 5 when the regulating piece 10 abuts against the mounting substrate 5. Held in posture.

As shown in FIG. 2, a holding member 12 that holds the lock member 6 in an unlocked posture against the urging force of the winding spring 9 is accommodated inside the mounting substrate 5, and the surface of the mounting substrate 5 (indoor An operation member 13 for releasing the holding by the holding member 12 is provided on the side surface.
The holding member 13 is made of a horizontally long metal plate housed inside the mounting substrate 5 so as to be movable to the left and right sides along the horizontal direction, and a pair of upper and lower latches that protrude and retract toward the housing recess 7. Claws 14 and 15 are provided at the tip.

A coil spring 16 that functions as a biasing member that constantly biases the holding member 12 toward the lock member 6 is housed inside the mounting substrate 5. Due to the spring force of the coil spring 16, the pair of upper and lower latching claws 14, 15 always project toward the housing recess 7.
An operation piece 17 that is exposed on the surface side of the mounting substrate 5 is formed in the middle in the longitudinal direction of the holding member 12, and the operation member 13 is directly connected to the operation piece 17.

For this reason, the holding member 12 can be moved in the same direction against the urging force of the coil spring 16 by operating the operating member 13 with a finger and sliding it in a direction away from the lock member 6. The pair of latching claws 14 and 15 are both drawn into the mounting substrate 5 from the storage recess 7.
The operation member 13 of the present embodiment is formed of a substantially rectangular block body having a curved surface, and is accommodated in a storage groove 18 formed on the surface of the mounting substrate 5. In addition, an arrow 19 indicating an operation direction by the operation member 13 when the lock member 6 is switched to the locked posture is engraved inside the storage groove 18.

  As shown in FIG. 2, in the present embodiment, a pair of locking members 6 and an operation member 13 are provided for one mounting substrate 5. These members 6 and 13 are arranged so as to be point-symmetric with respect to the center portion of the mounting substrate 5, and even if the mounting substrate 5 is mounted upside down, the auxiliary lock device 1 has exactly the same function. It has become something that plays. For this reason, the auxiliary lock device 1 can be attached to the outdoor sliding door 2 without the user having to worry about the vertical direction, and the attachment work of the auxiliary lock device 1 is easy in this respect.

Of the pair of upper and lower latching claws 14, 15 formed on the holding member 12, the first latching claw 14 far from the pivot shaft 8 is in the unlocked posture as the locking member 6 approaches or separates. This is for holding the unlocking and disengaging with the locking member 6.
For this reason, when the operation member 13 is operated to move the holding member 12 away from the lock member 6, the first latching claw 14 is detached from the lock member 6, and the lock member 6 is biased by the urging force of the winding spring 9. It swings to the lock posture side.

On the other hand, the second latching claw 15 closer to the pivot shaft 8 moves out of and into the swing path of the lock member 6 as it approaches or separates from the lock member 6, and moves back and forth in the swing path. Thus, the lock member 6 is for holding a lock that restricts the rocking of the lock member 6 to the unlocked posture.
For this reason, when the lock member 6 is in the locked posture, the operation member 13 is operated to move the holding member 12 in the direction away from the lock member 6, and the second latching claw 15 is moved to the lock member 6. The lock member 6 in the locked posture cannot be returned to the unlocked posture unless it is withdrawn from the swing path.

Next, the usage method and operation of the auxiliary lock device 1 of the present embodiment will be described.
First, when the auxiliary lock device 1 is attached to the glass 4 of the outdoor sliding door 2 and both the pair of lock members 6 are in the unlocked state (see FIGS. 2 and 3), the auxiliary lock device 1 is E (see FIG. 1) can be passed, and the sliding doors 2 and 3 can be moved along the sash frame.

  On the other hand, in order to lock the sliding doors 2 and 3 with the auxiliary lock device 1, the operation member 13 may be slid in the direction of the arrow 19. Then, the holding member 12 directly connected to the operation member 13 moves in a direction away from the lock member 6 against the urging force of the coil spring 16, whereby the first latching claw 14 is detached from the lock member 6, and the winding spring The lock member 6 is swung by the urging force 9 to be in a locked posture. When the lock member 6 is in the locked posture, the lock member 6 protrudes into the traveling path of the indoor sliding door 3, so that the sliding doors 2 and 3 cannot travel along the sash frame and are locked.

As described above, according to the auxiliary lock device 1 of the present embodiment, when the operation member 13 is operated to release the holding by the holding member 12, the lock member 6 swings to the lock posture side by the urging force of the winding spring 9. The lock member 6 can be automatically set to the locked posture.
Therefore, as compared with the conventional case where the lock member 6 adsorbed to the mounting substrate 5 by the magnetic force is rocked indoors against the magnetic force, the unlocking lock member 6 can be easily locked. Can be switched to.

If the first lock member 6A located on the upper side of the pair of lock members 6 is set to the lock posture, the sliding doors 2 and 3 in the closed state are supplementarily locked in addition to the lock by the crescent lock. (Closed lock).
Further, as shown in FIG. 1, by folding the first lock member 6A to the unlocked posture, and projecting the second lock member 6B located on the lower side from the mounting substrate 5 to the locked posture, The indoor sliding door 3 can be locked in a half-open state for ventilation (half-open lock).

On the other hand, in the auxiliary lock device 1 of the present embodiment, the holding member 12 is biased toward the lock member 6 by the coil spring 16, thereby accommodating not only the first latching pawl 14 but also the second latching pawl 15. It always protrudes into the recess 7.
For this reason, with respect to the lock member 6 once in the locked posture, the holding member 12 is moved in the direction away from the lock member 6 by the operation member 13 (the direction of the arrow 19 in FIG. 1), and the second latching claw The lock member 6 in the locked posture cannot be returned to the unlocked posture unless 15 is retracted from the swing path of the lock member 6.

  Therefore, even if the intruder breaks only the portion corresponding to the auxiliary lock device 1 of the glass 4 of the outdoor sliding door 2 and puts his hand indoors, the lock member 6 is brought into the unlocked posture unless the presence of the operation member 13 is noticed. For this reason, it is possible to prevent the auxiliary lock device 1 from being easily unlocked simply by returning the lock member 6 to the unlocked posture.

In addition, this invention is not limited to the said embodiment, For example, you may decide to provide only one lock member 6 with respect to one attachment board | substrate 5. As shown in FIG.
Moreover, when the clearance gap between the sliding doors 2 and 3 is large, the auxiliary | assistant lock apparatus 1 of this invention can also be affixed on the upper frame or the lower frame instead of the glass 4 of the outdoor sliding door 2. FIG.
