Description

[Detailed explanation of the invention] a. Purpose of the invention (industrial application field) The sliding door (including sliding doors and single sliding doors) that can be unlocked from the outside according to this invention can be used to open and close windows in buildings as well as to open and close windows in buildings. In the event of a fire, it will be used as an entrance for firefighting.

(Prior Art) Sliding doors as shown in FIG. 13 are widely used to open and close openings in buildings and the like. This sliding door has two inner and outer sliding door shoji 5a, 5b inside a sash frame 4 which is made up of a rectangular assembly of an upper frame 1, a lower frame 2, and left and right vertical frames 3, 3. It is built in such a way that it can be moved freely along the length of the building. The two sliding door shojis 5a, 5b each include an upper stile 6a, 6b, a lower stile 7a, 7b, a vertical stile 8a, 8b that faces the vertical frames 3, 3 when the sliding door is closed, and this vertical stile 8a, 8b and facing each other when the sliding door is closed.
A and 9b are combined into a rectangular shape, and glass is supported on the inner circumferential side of each frame. Matching frames 9a and 9b that constitute each sliding door shoji 5a and 5b
Of these, the crescent fittings 10 are attached to the matching frame 9a of the indoor sliding door 5a, and the crescent fittings 10 are attached to the outdoor sliding door 5b.
A receiving metal fitting (not shown) is provided in each of the connecting frames 9b at the part facing the crescent fitting 10, and when the sliding door is closed, the lever of the crescent fitting 10 is rotated to the closed state. The sliding door can be locked by engaging the crescent metal fitting 10 with the receiving metal fitting.

On the other hand, the Fire Service Act Enforcement Order stipulates that some windows on the third floor or higher that are located at a height of 31 meters or less must be used as fire entrances. For this reason,
When a sliding door is installed at a window opening on the third floor or above of a building, a mark is attached to the glass to indicate that it is an entrance. In the event of a fire,
Firefighters break through the glass with this mark on it and enter the building.

(Problems to be Solved by the Invention) However, when the above-mentioned sliding doors are used as an entrance for firefighting, the following inconveniences occur. In other words, if a building is constructed in a designated fire prevention area, the Fire Service Act requires that the glass used for sliding door shoji be glass with wire mesh. It is difficult to break through this with equipment, and it takes time to enter the building, wasting valuable time in extinguishing the fire and rescuing people.

The sliding door of the present invention that can be unlocked from the outdoors solves the above-mentioned inconveniences by being configured so that a locked sliding door can be easily opened from the outdoors without the use of special equipment. .

b. Structure of the invention (means for solving the problem) In the sliding door of the invention that can be unlocked from outside,
When a sliding door is closed, a side surface of the indoor side of the connecting member (including a connecting frame, a connecting mullion, and an intermediate mullion) facing each other on the indoor side is attached. a first elevating member that is connected to a rack that engages with a pinion that rotates as a first lever provided on the holder is rotated, and that moves up and down along the indoor side matching member as the first lever rotates; In addition, the outdoor matching member is also provided with a second elevating member that moves up and down along the outdoor matching member. The second elevating member and the first elevating member are configured to interlock with each other when the sliding door is in the closed state.

That is, the inner side of the indoor-side matching member is engaged with a pinion that rotates as the first lever for locking the sliding door provided on the matching member rotates, and the pinion is engaged with the pinion that rotates as the first lever for locking the sliding door provided on the matching member rotates. A first elevating member is connected to a rack that ascends and descends as the rack moves up and down, and a second elevating member that ascends and descends along the outdoor matching member is provided inside the matching member on the outdoor side.

On the side surface of the outdoor matching member exposed to the outdoors, as in the case of the indoor matching member, there is a second lever and a pinion that rotates as the second lever rotates. A lever device consisting of a rack that meshes with the pinion is provided, and a pin is installed in the rack of the lever device.

Further, of the first and second elevating members, a driving side block is fixed to the second elevating member, and a driven side block is fixed to the first elevating member. First and second elongated holes that are elongated in the vertical direction are formed in the facing surfaces of both the indoor and outdoor mating members, respectively, and both blocks are formed in the mating member with the respective blocks inside. The first thing I did was
A portion thereof protrudes from the second elongated hole, so that the protrusions can freely engage with each other when the sliding door is closed.

The pin attached to the lever device provided on the outdoor side joining member and the second elevating member are engaged with each other through the end of another elongated hole formed in the second elevating member, and When the lock is unlocked, the movement of the pin is transmitted to the second lifting rod.

(Function) Since the sliding door of the present invention that can be unlocked from the outdoors is constructed as described above, in the event of a fire, when the second lever provided on the outdoor connecting member is rotated, this lever will rotate. As the pinion rotates, the rack that meshes with the rotating pinion moves up and down, and as the pin installed in this rack moves, the second elevating member provided on the outdoor matching member moves up and down, and this matching A drive side block, which partially protrudes from a second elongated hole formed in the indoor side surface of the member, is raised and lowered. As the driving block moves up and down in this way, the driven block, which is partially engaged with the driving block, moves up and down inside the indoor matching member, and the first lifting member to which the driven block is fixed moves up and down. to raise and lower. As the first elevating member moves up and down, the rack moves up and down, the pin that engages with the rack rotates, and the first lever provided on the indoor connecting member rotates, unlocking the sliding door. be done.

(Example) Next, the present invention will be explained in more detail by explaining the illustrated embodiment.

1 to 3 show an embodiment of the present invention, in which FIG. 1 is a sectional view taken along the line AA in FIG. 13, and FIG. 2 is a view seen from the right side of FIG. 1.

Both indoor and outdoor sliding door shoji 5a, 5b (13th
Inside the connecting frames 9a and 9b in Figure), there are first and second elevating members 11a and 1, each having an H-shaped cross section.
1b is fitted so that it can be moved up and down. Among these, a driven side block 12 made of a slippery hard material such as nylon is installed in the middle part of the first elevating member 11a fitted inside the joining frame 9a of the indoor sliding door shoji.
A main body 13 is fixed with screws 14. This driven block 1
A first elongated hole 15 that is long in the vertical direction is formed in the portion where the two face each other.
A driven side plate piece 17 having a U-shaped vertical wall 16 formed on the outdoor side surface is loosely engaged with the driven side plate piece 17. This driven side plate piece 17
and the main body 13 are connected and fixed by screws 18, 18 to constitute the driven side block 12,
The surfaces of both members 17 and 13 that come into contact with each other are made into washboard-like uneven surfaces to prevent the driven side plate piece 17 from shifting relative to the main body 13 when the screws 18 and 18 are tightened.

On the other hand, in the middle of the second elevating member 11b, which is fitted inside the connecting frame 9b of the outdoor sliding door shoji 5b so as to be able to move freely only in the vertical direction, there is a part made of nylon or the like similar to the driven block 12. A main body 20 of the driven block 19 is fixed with screws 21. On the outdoor side surface of the joining frame 9b, a second long hole which is vertically elongated in the same way as the first long hole 15 is located between the drive side block 19 and the first long hole 15. A hole 22 is formed. A driving side plate piece 24 having a protrusion 23 formed on the interior side surface of the second elongated hole 22 so as to be able to freely enter the inside of the vertical wall 16 of the driven side plate piece 17 is loosely fitted into the second elongated hole 22. The drive side block 19 is fixed to the main body 20 by screws 25, 25. The contact surface between the main body 20 and the drive side plate piece 24 constituting this drive side block 19 is also a washboard-like uneven surface, similar to the case of the driven side block 12 described above, so that when the screws 25, 25 are tightened, the contact surface between the main body 20 and the drive side plate piece 24 is The side plate piece 24 is prevented from shifting with respect to the main body 20.

The driven side block 12 and the driving side block 19 formed as described above are connected to both the inside and outside sliding door shoji 5a,
5b is placed inside the sash frame (Fig. 13), the driven side plate piece 17 and the driving side plate piece 24 are arranged so that the protrusion 23 of the driving side block 19 enters inside the vertical wall 16 of the driven side block 12. Adjust the height.

For this reason, the first and second elevating members 11a, 11
When one of the elevating members 11a and 11b moves up and down, this movement is transmitted to the other elevating member based on the engagement between the driving block 19 and the driven block 12, and both the elevating members 11a and 11b move up and down. It will move up and down at the same time.

Of the first and second elevating members 11a and 11b fitted inside each of the interlocking frames 9a and 9b so as to be able to rise and fall freely, the first elevating member 11a fitted inside the indoor side interlocking frame 9a is , is configured to move up and down in accordance with the rotation of a first lever 26 provided on the side surface of the connecting frame 9a that is exposed to the indoor side. As shown in FIGS. 3 to 6, the first lever 26 is rotatably supported on a pedestal 27 fixed to the side surface of the joining frame 9a of the indoor sliding door 5a. hollow pedestal 2
7, the rotation shaft 28 of the first lever 26
A pinion 29 coupled to a pair of racks 3 is supported inside the pedestal 27 so as to be able to move up and down.
0 and 30, so that the respective racks 30 and 30 are raised and lowered in opposite directions as the lever 26 rotates. A pin 31 is implanted at the end of each rack 30, 30, and each pin 31, 31 is inserted into the upper half and lower half of the indoor side connecting frame 9a, respectively, so as to be able to rise and fall freely. The first elevating members 11a, 11a are fitted into circular holes 54, 54 bored at the ends thereof. Therefore, when the first lever 26 provided on the indoor side connecting stile 9a is rotated, the first elevating members 11a, 11a provided inside the upper and lower halves of this connecting stile 9a are moved. move up and down in opposite directions.

On the other hand, a second lever for unlocking the door from the outside when the sliding door is locked is provided on the side surface of the frame 9b of the outdoor sliding door 5b that is exposed to the outside. As shown in FIGS. 7 to 9, this second lever 32 has almost the same configuration as the first lever 26 described above, and as the lever 32 rotates, a pair of upper and lower pins 33, 33 are raised and lowered in opposite directions. However, since this second lever 32 is only for unlocking the sliding door shoji from the outside in the event of a fire, etc., it cannot be used for locking engagement like the one provided at the base of the first lever 26 described above. There are no standing walls.

Inside the outdoor side connecting frame 9b, second elevating members 11b and 11b are respectively fitted in the upper and lower halves so as to be able to move up and down, as in the case of the indoor side connecting frame 9a described above. I am wearing it. However, this second elevating member 11b, 11b and the second lever 32
The pair of pins 33, 33 that move up and down with the rotation of the sliding door shoji are not engaged in a state where the movement of one is directly transmitted to the other, and the sliding door shoji is in the locked state (the state shown in Fig. 7). Only when the second lever 32 is rotated in the unlocking direction, the movement of the pins 33, 33 is transmitted to the second elevating members 11b, 11b, and these elevating members 11b, 11b are shown in FIG. It is designed so that it can be moved to the unlocked state. That is, the distance between the pins 33, 33 is reduced as shown by the chain line in FIG. 8 only when the second lever 32 is moved in the unlocking direction. or,
Each pin 33, 33 is connected to each second elevating member 11.
It is made to fit into elongated holes 35, 35 formed at the ends of b, 11b, which are different from the first and second elongated holes 15, 22. Each second elevating member 11b, 11b is
When the first levers 26 are turned to the locked state with the sliding door closed, they are separated from each other as shown in FIG. 7, and when the first levers 26 are turned to the unlocked state, they are separated as shown in FIG. 8. They approach each other as shown by the solid lines. Therefore, when the second lever 32 is rotated to the locked state and the pins 33, 33 are separated from each other as shown in FIG.
Based on the operation of step 6, each of the second elevating members 11
Even if b and 11b rise and fall, each second elevating member 11
The movement of b and 11b is not transmitted to each of the pins 33 and 33. Furthermore, the second lever 32
Even if the first lever 26 is rotated between the locked state and the unlocked state while the first lever 26 is rotated to the locked state, each of the pins 33 inside the elongated holes 35, 35 , 33 only change.

The sliding door of the present invention that can be freely unlocked from the outdoors is constructed as described above, but in the event of a fire, a firefighter turns the second lever 32 provided on the connecting frame 9b of the outdoor sliding door shoji 5b. By doing so, the pins 33, 33 are moved from the solid line state to the chain line state in FIG. As the pins 33, 33 move, the second elevating members 11b, 11b, which had been in the state shown in FIG. 7, move to the state shown in FIG. 21, and the driven block 12, which is engaged with the protrusion 23 of the drive block 19 and the vertical wall 16, is inserted into the first frame 9a of the sliding door shoji on the indoor side. Lifting member 11a,
11a moves up and down. First elevating member 11a, 11
By raising and lowering the first lifting member 11a, 1
A pinion 29 meshed with the racks 30, 30 connected to the ends of 1a rotates, and a first lever 26 for locking has a rotating shaft 28 connected to this pinion 29.
Rotate in the unlocking direction.

Therefore, it becomes possible to move both sliding door shojis 5a, 5b in the opening direction without breaking the glass of the sliding door shojis 5a, 5b, and even if the above-mentioned glass is made of wire mesh, it will not take time to enter the room. . The window of this invention with a sliding door that can be unlocked from the outside is located at a height of 3rd floor or higher.
Locking a sliding door is not meant to prevent crime, but rather to prevent the sliding door from being opened inadvertently or to maintain airtightness, so the fact that it can be opened easily from outside is not a particular problem. In addition, when locking and unlocking the sliding door from the indoor side on a daily basis, the long holes 3 formed in the second elevating members 11b, 11b on the outdoor sliding door shoji side.
Only the relative displacement between 5, 35 and pins 33, 33,
The second lever 32 does not rotate. That is, when the second elevating member 11b moves up and down in conjunction with the first elevating member 11a, which moves up and down as the first lever 26 rotates, the pin 33 moves inside the elongated holes 35, 35. , the pin 33 itself does not move up and down, and the second lever 32 is prevented from rotating.

In the illustrated example, as the first lever 26 rotates, the second and first elevating members 11b and 11a, to which both the driving side and driven side blocks 19 and 12 are fixed, raise and lower each joining frame 9a. , 9b are actuated to drive pulling mechanisms provided at the upper and lower ends of both ends.

In order to maintain airtightness and soundproofing indoors and outdoors, the pulling mechanism is used to move each sliding door shoji 5a, 5b toward the indoor side when the sliding door shoji 5a, 5b is moved to the closed state and then locked. For example, a structure as shown in FIG. 10 or 11 is used. Of these, the first
In the structure shown in FIG.
a (in the case of the indoor sliding door shoji 5a; the same structure can be used for the outdoor sliding door 5b). The lower wedge piece 3 is movable and moves up and down at the lower end of the joining stile 9a in conjunction with the movement of the first elevating member provided in the lower half of the joining stile.
8 can freely abut against the upper end indoor side edge of the lower guide rail 39 on the upper surface of the lower frame, so that when the upper wedge piece 36 rises and the lower wedge piece 38 descends, both the upper and lower ends of the connecting stile 9a move toward the indoor side. I try to be drawn to it.

Furthermore, in the structure shown in FIG. 11, when the pair of upper and lower first elevating members 11a, 11a move in the opposite direction to the structure shown in FIG. Both end portions (only the lower end portion is shown in FIG. 11, but the upper end portion can also be constructed in the same way by simply turning it upside down) are constructed so as to be drawn toward the indoor side. That is, a pin 44 provided at the lower end of the lifting arm 43 is loosely engaged with an oblique elongated hole 42 formed at one end of an L-shaped crank piece 41 that is pivotally supported by the horizontal shaft 40 at the lower end of the connecting frame 9a. , connects the elevating arm 43 and the first elevating member 11a. As the first lever rotates in the locking direction, the first elevating member 11a rises, and when the elevating arm 43 is pulled up, the crank piece 41 rotates clockwise in FIG. The lower end of the piece 41 abuts against the indoor side surface of the lower guide rail 39 on the upper surface of the lower frame, and as a reaction, the joining stile 9a is drawn toward the indoor side.

Such a pulling mechanism may be provided on both the joining frame 9a of the indoor sliding door shoji and the joining stile 9b of the outdoor sliding door shoji, but even if it is provided only on either one, both the inside and outside sliding door shoji You can attract. For example, if a pulling mechanism is provided only on the outdoor side stile 9b, if both the inside and outside sliding door shoji are moved to the closed state and then the locking operation is performed to pull the stile 9b towards the indoor side, the closed state is reached. Indoor side stile 9 that matches this stile 9b
a is also pushed toward the indoor side, and the same effect as when this stile 9a is pulled toward the indoor side can be obtained. On the other hand, if the pulling mechanism is provided only on the indoor side stile 9a, the outdoor side stile 9b is connected to the indoor side stile 9a by the engagement of the crescent metal fitting and the receiving metal fitting when the door is locked. is also moved to the indoor side, and the same effect as that of drawing this connecting frame 9b to the indoor side can be obtained.

Further, the mechanism for drawing each of the connecting frames 9a, 9b toward the indoor side does not need to be the same mechanism at both the upper and lower ends of each of the connecting frames 9a, 9b, but different mechanisms may be used for the upper and lower ends. Also good. For example, for the indoor side connecting stile 9a, the first elevating member 11a is set to only one that spans almost the entire length of the connecting stile 9a, and the first elevating member 11a, which descends when the door is locked, lifts the connecting stile 9a. At the same time, the wedge piece at the lower end is brought into contact with the indoor side edge of the upper end of the lower guide rail 39 on the upper surface of the lower frame, and at the same time, the crank piece at the upper end is rotated. It is also possible to use the crank piece and the wedge piece upside down compared to the above case by setting the movement direction of the first elevating member 11a in the opposite direction during locking.

In this case, if necessary, a direction changing mechanism as shown in FIG. 12 may be employed in order to reverse the direction of elevation during locking. This direction changing mechanism has a pin 48 provided at one end of a rotary plate 47 which is rotatably supported by a shaft 46 at the intermediate portion of the substrate 45, and a first pin 48 that is fixed to the upper half of the substrate 45 so as to be movable up and down. The rotary plate 47
A pin 51 provided at the other end is loosely engaged with a horizontally long elongated hole 53 formed at the upper end of a second elevating plate 52 that is movably locked to the lower half of the substrate 45.
In such a direction change mechanism, when one of the elevator plates is raised or lowered, this movement is transmitted to the other elevator plate via the rotating plate 47, so that both elevator plates are raised or lowered in opposite directions in synchronization. Make it.

However, the sliding door of the present invention that can be unlocked from the outdoors does not necessarily need to be provided with a mechanism for pulling the sliding door shoji toward the indoor side.

c. Effects of the invention The sliding door of the invention that can be unlocked from the outdoors is constructed and operates as described above, so even when wire mesh glass is used for the sliding door shoji, it can be easily opened from the outdoors. When used as a firefighting entrance, effective firefighting and rescue operations can be carried out without wasting important time for firefighting activities.
