Description

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

(Prior Art) Sliding doors as shown in FIG. 7 are widely used to open and close openings in buildings and the like.
This sliding door consists of an upper frame 1, a lower frame 2, left and right vertical frames 3,
3 and 3 are assembled into a rectangular shape inside the sash frame 4,
Two sliding door shoji 5a and 5b, inside and outside, are built in such a way that they can be moved freely over the length direction of the upper and lower frames 1 and 2, respectively. The double sliding door shoji 5a, 5b are respectively upper stile 6a, 6b, lower stile 7a, 7b, and vertical stile 8 which faces the vertical frames 3, 3 when the sliding door is closed.
a, 8b, and matching frames 9a, 9 that are parallel to the vertical frames 8a, 8b and face each other when the sliding door is closed.
b are combined into a rectangular shape, and glass is supported on the inner circumferential side of each frame. Among the matching frames 9a and 9b that make up each sliding door shoji 5a and 5b, the crescent metal fitting 10 is attached to the matching frame 9a of the indoor sliding door 5a, and the crescent fitting 10 is attached to the matching frame 9b of the outdoor sliding door 5b. A receiving metal fitting (not shown) is provided in each portion facing the sliding door 10, and when the sliding door is closed, the crescent fitting 10 and the above-mentioned receiving metal fitting are connected by rotating the lever of the crescent fitting 10 to the closed state. When engaged, the sliding door can be locked.

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 proper 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,
For the inner and outer joining members (including joining frames, joining mullions, and intermediate mullions) that face each other when the sliding door is closed,
Elevating and lowering members are provided that move up and down within each member as levers provided on the respective matching members rotate, so that when the sliding door is in the closed state, the elevating and lowering members of both the inner and outer matching members interlock with each other. .

That is, a first elevating member is provided inside the indoor matching member, which moves up and down as the first lever for locking the sliding door provided on this matching member rotates. A second elevating member is provided inside the matching member and moves up and down as a second lever provided on the matching member rotates. Of both the first and second elevating members, a drive side block is fixed to the second elevating member, and a driven side block is fixed to the first elevating member. Long holes are formed in the vertical direction on the facing surfaces of both the indoor and outdoor mating members, and both of the blocks are partially opened from the long holes formed in the mating members with the respective blocks inside. When the sliding door is closed,
The protrusions can be freely engaged with each other.

(Function) Since the sliding door of the present invention that can be unlocked from the outdoors is constructed as described above, when a fire occurs, when the second lever provided on the outdoor-side alignment member is rotated, the outdoor-side alignment door can be unlocked. A second elevating member moves up and down inside the member, and raises and lowers a drive-side block that partially protrudes from a long hole formed in the indoor side surface of this combination member. 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. Based on the raising and lowering of the first elevating member, the first lever provided on the indoor-side matching member rotates, and the sliding door is unlocked.

Among these, the main body 18a of the driven block 18, which is fitted into the remaining part of the matching frame 9a so that it can only rise and fall, is inserted into the elongated hole 17a of the guide tube 11a fixed inside the matching frame 9a of the indoor sliding door shoji. A vertically long protrusion 19 formed on the side surface is freely movable only in the vertical direction, and the end face of the protrusion 19 and the first elevating member 15
while bringing the screws 20, 20 into close contact with the side surfaces of
The main body 18a is fixed to the first elevating member 15. A vertically elongated hole 21 is formed in the outdoor side surface of the connecting frame 9a, in a portion aligned with the main body 18a, and a driven side plate piece 18b is fitted into the elongated hole 21 so as to freely move only in the vertical direction. is fixed to the main body 18a with screws 22, 22. A U-shaped vertical wall 23 is formed on the outdoor side surface of the driven side plate piece 18b.

On the other hand, the elongated hole 17b of the guide tube 11b fixed inside the outdoor side connecting stile 9b is
A vertically long protrusion 25 formed on the side surface of the main body 24a of the drive side block 24 is fitted into the remaining part of the drive block 24 so that it can only move up and down. The end face of the main body 24a is brought into close contact with the side surface of the second elevating member 16, and the main body 24a is fixed to the second elevating member 16 with screws 26, 26. A vertically elongated hole 27 is formed in the indoor side surface of the outdoor side connecting stile 9b in a portion aligned with the main body 24a, and a driving side plate piece is fitted into the elongated hole 27 so as to be freely movable only in the vertical direction. 24b is fixed to the main body 24a with screws 28, 28. This drive side plate piece 24b
A protrusion 29 is provided on the indoor side surface of the driven side plate piece 18b so that it can enter into the inside of the vertical wall 23 formed on the outdoor side surface of the driven side plate piece 18b. This protruding part moves the indoor and outdoor sliding door shoji 5a, 5b (Fig. 7) to the closed state,
When facing each other, it enters the inside of the vertical wall 23, and the driving side plate piece 24b and the driven side plate piece 18b
so that they move up and down in synchronization.

The sliding door of the present invention that can be unlocked from the outdoors is constructed as described above, but in the event of a fire, a firefighter can turn the second lever provided on the connecting frame 9b of the outdoor sliding door shoji 5b. As a result, the pinion 14b in the connecting frame 9b is rotated counterclockwise in FIG. 2. As the pinion 14b rotates counterclockwise, the second elevating member 16, which has a lower half formed with a rack portion 16a that engages with the pinion 14b, descends, and the second elevating member 16 is attached to the screw 2.
a drive side block 24 fixed by 6, 26;
Through the driven block 18 which is engaged with the projection 29 of the drive block 24 and the vertical wall 23,
Guide tube 11 inside the stile 9a of the indoor sliding door shoji
The first elevating member 15 fitted in a lowers. As the first elevating member 15 descends, the pinion 14a that meshes with the rack portion 15a provided in the upper half of the first elevating member 15 rotates clockwise in FIG. The first lever for locking, into which the rotating shaft 13a is inserted, is rotated in the unlocking direction. The direction in which each lever rotates when unlocking is often opposite to the illustrated example.

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. . Since the windows with sliding doors that can be unlocked from the outdoors according to the present invention are located at a height of 3rd floor or higher, locking the sliding doors has no meaning in crime prevention and prevents the sliding door shoji from being opened inadvertently. Since the purpose is to prevent or maintain airtightness, it is not a particular problem that it can be easily opened from outside.

In the illustrated example, as the pinions 14a and 14b rotate, both the driving side and driven side blocks 24, 1
Separately from the second and first elevating members 16, 15 to which the frame 8 is fixed, the third and fourth elevating members 30, 31 are raised and lowered inside the respective guide tubes 11a, 11b, and each connecting frame 9a, 9b is raised and lowered. It is designed to drive pulling mechanisms provided at both the upper and lower ends of the.

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. 4 or 5 is used. Among these, the structure shown in FIG. 4 is a structure that moves in conjunction with the movement of the first elevating member 15 to move the stile 9a (in the case of an indoor sliding door shoji 5a).
The same structure can be applied to the outdoor sliding door 5b. )
The upper wedge piece 32 that moves up and down at the upper end can freely abut against the lower end indoor side edge of the upper guide rail 33 on the lower surface of the upper frame, and moves up and down at the lower end of the connecting frame 9a in conjunction with the movement of the fourth lifting member 31. The lower wedge piece 34 can freely collide with the upper indoor side edge of the lower guide rail 35 on the upper surface of the lower frame, so that when the upper wedge piece 32 rises and the lower wedge piece 34 descends, both the upper and lower ends of the connecting frame 9a are drawn toward the indoor side.

Furthermore, in the structure shown in FIG. 5, when the first and fourth elevating members 15, 31 move in the opposite direction to the structure shown in FIG. (Although only the lower end portion is shown in FIG. 5, the upper end portion can also be constructed in the same manner by simply turning it upside down.) is constructed so as to be drawn toward the indoor side. That is, the pinion 40 provided at the lower end of the elevating arm 48 is loosely engaged with the oblique elongated hole 38 formed at one end of the L-shaped crank piece 37 which is pivotally supported by the horizontal shaft 36 at the lower end of the connecting frame 9a. , lifting arm 48
and the fourth elevating member 31 are connected. As the first lever rotates in the locking direction, the fourth elevating member 31 rises, and when the elevating arm 48 is pulled up, the crank piece 37 rotates clockwise in FIG. The lower end of the piece 37 abuts against the indoor side surface of the lower guide rail 35 on the upper surface of the lower frame, and as a reaction, the 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 frame 9a, the third lifting member 30 is omitted, and the wedge piece at the lower end of the connecting frame 9a is guided to the lower part of the upper surface of the lower frame by the second lifting member 16 that descends when the door is locked. At the same time as the upper end of the rail 35 is brought into contact with the indoor side edge, the crank piece at the upper end is rotated,
This crank piece is attached to the upper guide rail 33 on the lower surface of the upper frame.
It can also be made to abut against the indoor side of the
It is also possible to use the third elevating member 30 with the crank piece and the wedge piece upside down compared to the above case.

In this case, if necessary, a direction changing mechanism as shown in FIG. 6 may be employed in order to reverse the direction of elevation during locking. This direction changing mechanism has a first pin 41 provided at one end of a rotary plate 40 which is rotatably supported by a shaft 39 at an intermediate portion of the substrate 47, and which is fixed to the upper half of the substrate 47 so as to be movable up and down. A second pin 44 provided at the other end of the rotary plate 40 is engaged with a horizontally elongated hole 43 formed at the lower end of the elevating plate 42, and is latched to the lower half of the base plate 47 so as to be movable up and down. It is made to fit into a horizontally long elongated hole 46 formed at the upper end of the elevating plate 45. In such a direction changing mechanism, when one of the elevating plates is raised or lowered, this movement is transmitted to the other elevating plate via the rotary plate 40, so that both elevating plates are raised or lowered in opposite directions in synchronization. Make it.

However, the sliding door of this invention that can be unlocked from outside is
It is not necessarily necessary to provide a mechanism to draw the sliding door shoji indoors.

In addition, the mechanism for transmitting the rotational movement of the first and second levers as vertical force to both the driving side and driven side blocks may be a rack and pinion as in the example shown, or a link mechanism or other conventional mechanism. You can adopt what is created. In this case, it is necessary that the direction of force transmission be reversible.

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