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 Patent Document 1, an auxiliary lock for a sliding door provided with a mounting board that can be attached to the indoor side surface of the glass of an outdoor sliding door, and a lock member that is swingable up and down on the mounting board. The device has already been developed.
In this case, the lock member is made of a plate material pivotally attached to the mounting substrate so as to be swingable up and down about the horizontal axis, and is unlocked from the traveling path of the indoor sliding door (FIG. 2A of Patent Document 1). ) And a locked posture (the state shown in FIG. 2B of Patent Document 1) protruding into the traveling path of the indoor sliding door.

And according to this conventional auxiliary lock device, when the lock device is attached to the corner of the outdoor sliding door, in addition to the main locking by the crescent lock, both the sliding doors in the closed state are supplementarily locked. be able to. In addition, when the said locking device is affixed from the center part of an outdoor sliding door, both sliding doors can be locked in the state which opened the indoor sliding door halfway for ventilation.
Utility Model Registration No. 3054429

In the conventional auxiliary lock device, a plate-like magnet that attracts the other to one of the lock member and the mounting substrate is attached, and the lock member is always held in the unlocked posture by this magnet.
For this reason, when the lock member is swung to the lock posture side in order to lock both sliding doors, the user needs to swing the lock member to the indoor side with a force larger than the magnetic force of the magnet. There is a drawback in that the operation to make the locked posture is complicated.

In particular, in the above-described conventional auxiliary lock device, the lock member is held in the unlocked position by magnetically adsorbing the lock member to the mounting substrate. For example, the lock member is adsorbed to the mounting substrate in a frozen state in winter. In this case, it may be very difficult to swing the lock member toward the lock posture.
Accordingly, an object of the present invention is to improve the operability of the auxiliary lock device by allowing the auxiliary lock device of the sliding door to be locked by a simple push operation.

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 a contact portion that protrudes into the running path of the indoor sliding door by being pushed toward the outdoor side, and the holding by the holding member is released when the indoor sliding door collides with the contact portion. And a switch member to be 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. Release the unlocking by the switch member.
Then, the switch member has a contact portion that protrudes to the traveling path of the indoor sliding door by being pushed toward the outdoor side, and the indoor sliding door collides with the contact portion so that the holding member holds it. Since it is made to cancel | release, when locking an auxiliary | assistant locking device, a user only needs to push the said switch member to the outdoor side.
Therefore, the lock operation with respect to the auxiliary lock device is simplified compared to the conventional case where the lock member that is attracted to the mounting substrate by the magnetic force is rocked indoors against the magnetic force.

In the present invention, the number and position of the switch members are not particularly limited, but the switch member is provided with a pair of left and right switch members with respect to one mounting board. It is preferable that they are arranged so as to be line-symmetric with respect to the center line of the mounting substrate.
In this case, since the auxiliary lock device is locked by any of the pair of left and right switch members, even if the outdoor sliding door is left-opened or right-opened, one auxiliary lock device can be used as the auxiliary lock device. The versatility of the apparatus can be improved.

Moreover, in this invention, it is preferable that the said holding member is arrange | positioned between the said switch members so that it can operate by any member of a pair of said left and right said switch members.
In this case, since one holding member can be operated regardless of which of the pair of left and right switch members is operated, the number of parts of the holding member does not increase even when a plurality of switch members are provided. An auxiliary lock device which is advantageous in terms of manufacturing cost can be obtained.

  As described above, according to the present invention, the auxiliary lock device for the sliding door can be locked only by a simple push operation, and therefore the operability of the auxiliary lock device can be improved.

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

I have.
The lock member 6 is pivotally attached to the lower side of the central portion of the mounting substrate 5 so as to be able to swing up and down. The unlocking posture (the solid line state in FIG. 1) deviating from the travel path of the indoor sliding door 3 and the indoor sliding door 3 It is possible to switch to a locked posture (imaginary line state in FIG. 1) protruding into the travel route.

As shown in FIGS. 2 to 4, the mounting substrate 5 is formed of an aluminum alloy box that is flat and hollow and is chamfered in both upper and lower edges, and an adhesive is attached to the back side of the mounting substrate 5. An adhesive layer (not shown) made of an adhesive or the like 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 of the lock member 6 is formed at the center of the mounting substrate 5 and from below (see FIGS. 2 and 4). A horizontal pivot shaft 8 is installed on the upper side of the housing recess 7, and the lock member 6 can swing up and down by passing the pivot shaft 8 through the proximal end of the lock member 6. Are pivotally attached to the mounting substrate 5.
As shown in FIG. 4, 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. 4A) 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 of the indoor sliding door 3. Has been.
The lock member 6 is made of a substantially rectangular stainless steel plate, and swings downward and becomes unlocked when the entirety is stored in the storage recess 7, and swings upward by 90 degrees from this position. Thus, the lock posture is projected perpendicular to the mounting substrate 5.

A winding spring 9 that functions as a biasing member that constantly biases the lock member 6 toward the locking posture is wound around the pivot shaft 8, and the lock member 6 swings around the upper edge of the lock member 6. A restricting piece 10 (see FIG. 4A) for restricting the angle to approximately 90 degrees is formed.
For this reason, the lock member 6 urged toward the lock posture by the winding spring 10 is brought into contact with the bottom surface of the storage recess 7 so that the lock member 6 projects perpendicularly to the mounting substrate 5. Is held in a locked position.

As shown in FIGS. 2 and 3, a holding member 12 that holds the lock member 6 in the unlocked posture against the urging force of the winding spring 9 is accommodated in the mounting substrate 5. On the upper side, a pair of left and right switch members 13R and 13L for releasing the holding by the holding member 12 is provided.
Of these, the holding member 12 is a vertically long bar-shaped member housed in the central portion of the mounting substrate 5 so as to be movable in the vertical direction, and the retaining piece 14 that moves back and forth toward the housing recess 7 is provided. It is provided at the lower end.

Also, a leaf spring 15 (see FIG. 2) that functions as a biasing member that constantly biases the holding member 12 toward the lock member 6 (lower side) is housed in the inner space on the upper side of the mounting substrate 5. ing. The leaf spring 16 has an arcuate shape in which a central portion curves downwardly in a front view.
Then, the holding member 12 that can move up and down is stored in the mounting substrate 5 with the upper end of the holding member 12 in contact with the curved portion of the leaf spring 15. The latching piece 14 always protrudes toward the storage recess 7.

The latching piece 14 formed on the holding member 12 is used for holding the unlocking to be engaged with and disengaged from the locking member 6 in the unlocking posture as the locking member 6 approaches or separates. That is, the upper end portion of the lock member 6 is formed with a hooking hole 16 for restricting upward swinging of the lock member 6 by the hooking piece 14 being hooked.
For this reason, while the locking piece 14 of the holding member 12 is inserted into the locked hole 16, the lock member 6 is held in the unlocked posture, but the direction in which the holding member 12 is separated from the lock member 6 ( When it moves upward, the latching piece 14 is disengaged from the latched hole 16, and the lock member 6 swings upward to the lock posture side by the urging force of the winding spring 9.

As shown in FIGS. 1 and 2, the pair of left and right switch members 13 </ b> R and 13 </ b> L are mounted on a slide frame 17 provided on the upper portion from the center portion of the mounting substrate 5. The slide frame 17 is accommodated in the mounting substrate 5 so as to be horizontally movable in the left-right direction, and is formed of a hollow frame having a length substantially the same as the lateral width of the mounting substrate 5.
The pair of left and right switch members 13R and 13L are both symmetrical with respect to the center of the slide frame 17 and have the same function in terms of the release function with respect to the holding member 12. Therefore, in the following, the right switch The structure of the switch member will be described taking the member 13R as an example.

As shown in FIGS. 2 and 3, the switch member 13 </ b> R is made of a substantially horizontally long rectangular plate and is housed in a housing groove portion 18 formed on the right side portion of the slide frame 17. A midway portion of the switch member 13R is rotatably supported by a support shaft 19 provided in the storage groove 18 in the vertical direction.
The support shaft 19 is mounted on the slide frame 17 so that both end support portions thereof can move linearly within a predetermined range in the left-right direction, and is moved to the center in the left-right direction by a coil spring 20 provided in the storage groove portion 18. Always energized.

For this reason, the switch member 13R is swingable with respect to the front and back direction of the mounting substrate 5 (vertical direction in FIG. 3).
Further, a contact portion 21 having a substantially L-shaped cross section is formed at the tip edge portion (end portion on the outer side in the left-right direction) of the switch member 13R, and an engagement groove portion 22 is formed on the inner surface side of the contact portion 21. Has been. Further, the storage groove portion 18 of the slide frame 17 is formed with an inclined cam surface 23 on which the base end edge portion of the switch member 13R can be detachably mounted.

Therefore, in a non-operating state in which the switch member 13R is not pushed (the state of the switch member 13L on the left side in FIG. 3), the engaging groove 24 formed on the slide frame 17 is the engaging groove portion 22 of the contact portion 21. The switch member 13 </ b> R is held in a state of being housed in the storage groove 18 of the slide frame 17.
On the other hand, when the base end portion of the switch member 13R is pushed, the support shaft 19 moves to the right against the coil spring 20, and the base end edge portion of the switch member 13R rides on the inclined cam surface 23 and is positioned. Accordingly, the posture is maintained in the operation state (the state of the switch member 13R on the right side in FIG. 3) in which the contact portion 21 protrudes indoors (the lower side in FIG. 3).

The slide frame 17 of the present embodiment has a substantially triangular slide piece 25 (see FIG. 2) at the center, and the slide piece 25 is a push-up formed at the center of the holding member 12. It abuts on the cam surface 26.
The sliding surface where the slide piece 25 and the cam surface 26 come into contact with each other is such that the holding member 12 moves when the slide frame 17 moves in either the left or right direction from the neutral position where the center line coincides with the mounting substrate 5. It is inclined in the direction of moving upward.

Therefore, when the right switch member 13R is in the operating state, when the indoor sliding door 3 collides with the contact portion 21, the slide frame 17 moves from the neutral position to the left side.
Accordingly, as the slide frame 17 moves, the slide piece 17 pushes the holding member 12 upward via the cam surface 26, and the unlock holding by the holding member 12 with respect to the lock member 6 is released.

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, the lock member 6 is in the unlocked posture (see FIG. 1), and the left and right switch members 13R and 13L are in an unoperated state. The auxiliary lock device 1 can pass through the gap E (see FIG. 1), and the sliding doors 2 and 3 can travel along the sash frame.

On the other hand, when the auxiliary lock device 1 wants to lock both the sliding doors 2 and 3, the user may push the base end portion of the right switch member 13R toward the outdoor side.
Then, as shown in FIG. 1, the contact portion 21 of the right switch member 13R protrudes into the traveling path of the indoor sliding door 3, and the switch member 13R enters the operating state. When the switch member 13R is in the operating state, when the outdoor sliding door 2 or the indoor sliding door 3 is forced to be opened, the vertical frame of the indoor sliding door 3 collides with the contact portion 21 of the switch member 13R.

As a result, the slide frame 17 moves to the left and the holding member 12 is pushed upward by the slide piece 25. Then, the unlocking holding by the holding member 12 is released, the latching piece 14 is detached from the locking member 6, and the locking member 6 swings by the urging force of the winding spring 9 to be in the locked posture.
When the lock member 6 is in the locked posture in this way, the lock member 6 protrudes into the travel path of the indoor sliding door 3, so that the sliding doors 2 and 3 are locked in earnest.

As described above, according to the auxiliary lock device 1 of the present embodiment, the auxiliary lock device 1 can be locked only by a very simple lock operation in which one switch member 13R is pushed once with a finger. .
Therefore, as compared with the conventional case where the lock member 6 adsorbed to the mounting substrate 5 by magnetic force is swung to the indoor side against the magnetic force, the lock operation for the auxiliary lock device 1 is very simple. Become.

  Further, in the auxiliary lock device 1 of the present embodiment, since the lock operation with respect to the auxiliary lock device 1 can be performed by any one of the pair of left and right switch members 13R, 13L, the outdoor sliding door 2 is opened left or right. In any case, one auxiliary lock device 1 can be used also, and the versatility of the auxiliary lock device 1 can be improved.

Furthermore, in the auxiliary lock device 1 of this embodiment, the holding member 12 can be operated by any member of the pair of left and right switch portions 13R, 13L, so that the switch members 13R, 13L on the mounting substrate 5 are operated. Arranged between.
For this reason, since the unlock holding of the same holding member 12 can be released regardless of which of the pair of left and right switch members 13R and 13L is operated, the number of parts of the holding member 12 increases even when a plurality of the switch members are provided. This is advantageous in terms of materials and manufacturing costs.

The present invention is not limited to the above embodiment. For example, the switch members do not necessarily have to be provided as a pair on the left and right, and may be a single member.
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.

  It is a perspective view which shows the auxiliary | assistant lock apparatus of this invention, and its installation state.   The right side of the auxiliary locking device is a front view made of a cross-sectional view.   It is a top sectional view of a slide frame portion of the auxiliary lock device.   It is side surface sectional drawing seen from the right side of the said auxiliary | assistant lock apparatus, (a) shows the state of a locking member in an unlocking attitude | position, (b) shows the state of a locking member in a locking attitude | position.
