Description

[Detailed explanation of the invention] a. Purpose of the invention (industrial application field) The sliding door of this invention that can be unlocked from the outside is used to open and close the windows of a building, and also to be used as an entrance for firefighting in the event of a fire. .

(Prior Art) Sliding doors as shown in FIG. 8, for example, 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 made up of a rectangular upper frame 1, a lower frame 2, and left and right vertical frames 3, 3, respectively. 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.
In the connecting frame 9b, a receiving metal fitting (not shown) is provided in the part facing the crescent metal fitting 10, and by rotating it when the sliding door is closed, this crescent metal fitting 10 and the above-mentioned receiving metal fitting can be connected. 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 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, an elevating member is provided that moves up and down within the matching member in response to the rotation of a lever provided on the inner and outer matching members (including matching frames, matching mullions, and intermediate mullions) that face each other. When the sliding door is closed and locked, the elevating and lowering members of both the inner and outer connecting members can be freely interlocked, and the sliding door can be unlocked by rotating a lever provided on the outdoor connecting member. There is.

That is, on the inside of the indoor side matching member, there is provided a first elevating member that moves up and down in accordance with the rotation of the first lever for locking the sliding door provided on this matching member, and on the outdoor side. 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 surfaces of both the indoor and outdoor binding members that face each other, and both of the blocks have elongated holes formed in the binding member that is equipped with an elevating member to which each block is fixed. A portion is made to protrude from the hole, and the protrusions can be freely engaged with each other.

Furthermore, in the sliding door of the present invention that can be unlocked from the outdoors, there is a member that moves in synchronization with the lifting and lowering of the second elevating member provided inside the outdoor matching member, and a member that moves in synchronization with the elevation of the second elevating member provided inside the outdoor matching member. A member that moves in synchronization with the rotation of the provided second lever is freely engaged with the member. The relationship between the two above-mentioned members that play with each other is such that when the drive block in the outdoor matching member moves up and down as the first lever provided on the indoor matching member rotates in the locking direction. The relationship between the loose ends is such that the end portions move toward each other and when the locking operation is completed, the loose ends can no longer be displaced.

(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 connecting member is rotated, the sliding door will come into contact with each other. Force is transmitted between the members that have entered the room but are unable to move any further, and the second elevating member moves up and down inside the matching member on the outdoor side, and a layer is formed on the indoor side of this matching member. The drive side block, which partially protrudes from the elongated hole, 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. 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.

When the first lever provided on the indoor matching member is rotated from the locked state to the unlocked state, the member that moves in synchronization with this first lever will rotate to the outdoor second lever. Because it is displaced relative to the synchronously moving members and no force is transmitted between the two members,
The second lever on the outdoor side does not rotate.

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

The drive side block 24 is fixed by the drive side block 24, and the driven side block is engaged with the protrusion 29 of the drive side block 24 and the vertical wall 23, and is fitted into the guide tube 11a in the joining frame 9a of the indoor sliding door shoji. The first elevating member 15 lowers. As the first elevating member 15 descends, the pinion 14a meshing with the rack portion 15a provided in the upper half of the first elevating member 15 rotates clockwise in FIG.
The first locking lever, in which the rotating shaft 13a is inserted into the pinion 14a, 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. . The windows with sliding doors that can be unlocked from the outdoors according to the present invention are located on the third floor or higher, so locking the sliding doors has no meaning in terms of 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.

When the sliding door is locked or unlocked from the indoor side by rotating the first lever provided on the joining frame 9a of the indoor sliding door shoji, the pin 35 on the unlocking lever 32 side is , within the long hole 31 of the disc 30 that rotates as the first lever rotates.
Since it only moves relative to 1, the unlocking lever provided on the outdoor side does not rotate when unnecessary.

The relationship between the elongated hole 31 and the pin 35 will be explained in more detail with reference to FIG. 6. When the first lever provided on the indoor connecting frame 9a is rotated in the unlocking direction, The elongated hole 31 and the pin 35 are in the state shown in FIG. 6, but when the first lever is rotated in the locking direction, the disc 30 with the elongated hole 31 opened is in the state shown in FIG. Rotate 180 degrees clockwise,
Pin 35 that remains in the position shown in Figure 6
is now moved to the opposite end of the elongated hole 31. When the disc 34 is rotated 180 degrees clockwise in FIG. 6 by rotating the unlocking lever 32 from this locked state, the disc 30 fixed on the rotating shaft 13a side is rotated.
rotate in the same direction, rotating the first lever in the unlocking direction.

In the illustrated example, as the pinions 14a and 14b rotate, both the driving side and driven side blocks 24, 2
Separately from the second and first elevating members 16, 15 to which the frame 8 is fixed, third and fourth elevating members 37, 38 are raised and lowered inside each guide tube 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 close each sliding door shoji 5a, 5b when the sliding door shoji 5a, 5b is moved to the closed state and then locked. It causes a slight parallel movement inward, and various conventionally known structures can be used.

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.

In addition, the mechanism for transmitting the rotational movement of the first and second levers to both the driving and driven blocks as a force in the vertical direction can be a rack and pinion as in the example shown, or a link mechanism or other conventional mechanism. The link mechanism, etc. can have a playable part between the elongated hole and the pin in the middle of the link mechanism. In this case, it is necessary that the direction of force transmission be reversible.

Furthermore, the structure for allowing the disks 30 and 34 to play with each other can be constructed by reversing the side where the pin 35 and the elongated hole 31 are provided from the case shown in the figure, and by using a clutch mechanism as shown in FIG. You can also do it. This clutch mechanism includes projections 39 and 4 on the side surfaces of each disk 30 and 34.
0, and acts so that force is transmitted between the two disks only when both the protrusions 39 and 40 abut against each other.

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. Further, in normal use, the unlocking lever provided on the outdoor side does not move, and this lever does not become an eyesore.
