Description

[Detailed description of the invention] (Industrial application field) The emergency entrance window according to this invention is used as an entrance window for firefighting. When a fire occurs, a firefighter uses a ladder truck to reach the outside of the entrance window, opens the window from the outside, and enters the building to extinguish the fire and carry out rescue operations.

(Prior Art) Windows of various structures are used for openings in buildings. For example, the window shown in Figure 10 is used for both daylighting and ventilation, and the window opening 1
A window shoji 2 is attached to the inside of the window so that it can freely swing around a pivot 3 at one end.

When this window is closed, the window shoji 2 is placed in the solid line position in FIG. 10. In addition, when ventilation is performed, the window shoji 2 is closed to the window opening 1, as shown by the chain line a in the same figure.
Pull it out a little (for example, about 10 degrees) from the inside. Furthermore, when cleaning the outdoor surface of the glass constituting the window sash 2, the window sash 2 is further pulled out from inside the window opening 1, as shown by the chain line b in the figure.

On the other hand, the Fire Service Act Enforcement Order stipulates that some windows on the third floor or above that are located at a height of 31 meters or less must be used as fire entrances. For this reason,
When a window opening 1 on the third floor or above of a building is provided with an opening/closing window as shown in FIG. 10, a mark is attached to the glass of the window shoji 2 to indicate that it is an entrance. In the event of a fire, firefighters will break the glass marked with this mark and enter the building.

(Problems to be Solved by the Invention) The emergency access window of the present invention is intended to facilitate fire extinguishing work and ensure the safety of those working below the emergency access window.

If a conventional emergency access window is simply a mark affixed to the window, and if a fire breaks out, firefighters must break the glass before entering the building. It may fall and pose a danger to those fighting the fire below.

Moreover, if the glass is made of wire mesh (if the building is constructed in a designated fire prevention area, it is mandatory to use wire mesh), it is difficult to break it with a simple tool such as a hammer, and the building It takes time to get inside, and valuable time is wasted in extinguishing the fire.

In view of these circumstances, the micro film of Utility Application No. 57-90339 (Utility Model Application No. 58-191254) has a handle provided on the outdoor side of the window shoji that allows the window shoji to be operated from the outdoor side. A structure that can be opened freely is described.

According to the structure described in this microfilm, it is possible to enter indoors without breaking the glass, so there is no problem as described above, but there are still problems that need to be improved as described below.

That is, in the case of the structure described in the above-mentioned microfilm, the rod is raised by operating the handle on the outdoor side and the window sash can be opened. It is the rod itself that makes it possible.

Therefore, when opening window shoji from the outdoor side,
Including the handle for normal opening and closing provided on the indoor side.
All mechanisms for normal opening and closing must be displaced. In particular, moving the deceleration mechanism installed between the rod and the normal opening/closing handle from the opposite side and displacing this handle requires a large amount of force, so it is necessary to displace the handle on the outdoor side. The power increases.

In case of a fire emergency, it is preferable that the force required to operate the window opening handle be as small as possible, considering that it is necessary to enter the room as quickly as possible.

The emergency access window of the present invention was devised in view of the above-mentioned circumstances.

(Means for Solving the Problems) The emergency access window of the present invention consists of upper and lower horizontal frames and left and right vertical frames. Surrounded on all sides by frames,
A window shoji that can be opened and closed by rotating around a vertical axis and is built inside the window frame, a first handle provided on the outdoor side of the window frame, and a a first elevating member that is movable along the vertical frame and moves up and down based on the operation of the first handle; a second handle provided on the indoor side of the window shoji; a second elevating member that rises and lowers independently of the first elevating member based on the operation of the second handle; and a cam block fixed to one of the first elevating member and the second elevating member. is fixed to the other of the first lifting member and the second lifting member, and collides with the cam block based on the relative displacement between the first lifting member and the second lifting member when the window sash is closed. It comprises a collapsible abutment piece and a packing that is attached to each frame constituting the window frame and presses against the side surface of each frame constituting the window sash when the abutment piece and the cam block abut each other. There is.

(Function) The function of the emergency entrance window of the present invention configured as described above is as follows.

In normal times (when there is no fire), when opening a closed window sash for ventilation or cleaning, a second handle provided on the indoor side of the window sash is operated. Based on the operation of this second handle,
A second elevating member moves up and down along the vertical stile. At this time, since the first handle provided on the outdoor side of the window frame is not operated, the first elevating member does not rise or fall.

In this way, as the second elevating member moves up and down while the first elevating member remains stationary, the cam block or abutment piece fixed to the second elevating member and the abutment piece fixed to the first elevating member One side or the cam block will come out of contact.

When the cam block and the abutting piece are disengaged, the force that presses the side of the stile that makes up the window sash against the packing attached to the window frame is released, and the window shoji is rotated around its vertical axis. , can be opened.

When closing, contrary to the above case, rotate the window shoji in the closing direction and store it inside the window frame, then rotate the second handle in the opposite direction to the opening operation, and open the first elevating member. While keeping the cam block and the abutting piece stationary, the second elevating member is raised and lowered to bring the cam block and the abutment piece into abutment with each other.

In addition, when a closed window shoji is opened from the outside in the event of a fire, the first handle provided on the outside side of the window frame is operated. Based on the operation of the first handle, the first operating member moves up and down along the vertical frame. At this time, since the second handle provided on the indoor side of the window sash is not operated, the second elevating member does not rise or fall.

In this way, as a result of the first elevating member moving up and down while the second elevating member remains stationary, the cam block or abutment piece fixed to the second elevating member and the abutment piece fixed to the first elevating member One side or the cam block will come out of contact.

As a result, as in the case of opening from the indoor side, the force pressing the side surfaces of the stile that makes up the window shoji against the packing attached to the window frame is released, and the window shoji can be rotated about its vertical axis. By doing so, it can be opened.

(Example) Figures 1 to 9 show examples of the emergency access window of the present invention.

In the emergency access window of the present invention, as shown in FIG. 5, a window frame 6 consisting of upper and lower horizontal frames 4, 4 and left and right vertical frames 5, 5 is fixed inside the window opening. Inside this window frame 6, a window shoji 2 is built in which the four circumferences of the glass 9 are surrounded by upper and lower horizontal frames 7, 7 and left and right vertical frames 8, 8. Then, by connecting the vertical stile 8 and the vertical frame 5 on one side (left side in FIG. 5) of the window shoji 2 to each other with a hinge (not shown),
The windows can be opened and closed freely.

A first handle (not shown) is attached to the outdoor side surface of the vertical frame 5 of the window frame 6 and the window shoji 2 (on the right side in FIG. 5). The first handle allows the first elevating member 11 shown in FIGS. 1 and 2 to be driven up and down along the vertical frame 5.

Elongated holes 12, 12 that are long in the vertical direction are formed in two positions on the upper and lower sides of this first elevating member 11. The guide pins 46, 46 are loosely aligned with each other. The first elevating member 11 has each elongated hole 1

Cam blocks 13, 13 are fixed at two positions above and below the surface facing the outer surface of the vertical frame 8, which is a part of the first elevating member 11 mounted on the inner surface of the vertical frame 5 in this manner. are doing.

The outdoor side surfaces of the cam blocks 13, 13 are formed as cam surfaces 15 which abut against roller-shaped abutting pieces 14, 14, which will be described later. The middle part of this cam surface 15 is a vertical part 15a, and above and below this vertical part 15a,
The closer to the end of the cam surface 15 (the farther away from the vertical part 15a) the inclined parts 15b, 15b are formed which approach the indoor side (the right side in FIG. 2).

Further, a pin 16 is implanted on the inner surface of the intermediate portion of the first elevating member 11. And this pin 1
6 is fitted into a U-shaped notch 47 formed at one end of the drive arm 17 (the right end in FIG. 2).
The middle part of the drive arm 17 is pivotally supported by a support bracket 18 fixed to the inner surface of the vertical frame 5, and the other end is movable up and down by a first handle provided on the outdoor side of the vertical frame 5. There is. Therefore, when the first handle is operated, the first elevating member 11 moves up and down via the drive arm 17 and pin 16.

On the other hand, a second handle 19 is provided on the indoor side surface (left side surface in FIG. 3) of the vertical stile 8 of the window sash 2 for opening and closing the window sash 2 from the indoor side. This second handle 19 is attached to the outer surface of the vertical stile 8.
A second elevating member 20 is provided which is driven by the operation of and moves along the vertical frame 8.

Also, the upper and lower portions 2 of the outer surface of this second elevating member 20
Pivot shafts 45, 45 are implanted at certain positions, and roller-shaped abutment pieces 14, 14 are rotatably supported on each pivot shaft 45, 45. Each abutting piece 14, 14 is
As the window shoji 2 is closed, the outer surface of the vertical stile 8 and the inner surface of the vertical frame 5 are in a state where they are opposed to each other.
Cam surfaces 15, 15 of the cam blocks 13, 13
It can be freely collided with.

On the other hand, a pin 37 is implanted on the inner surface of the intermediate portion of the second elevating member 20. This pin 37 and a U-shaped notch 48 formed in the elevating plate 38 shown in FIG. 6 are engaged with each other. This elevating plate 38 is driven up and down by the second handle 19.

That is, this second handle 19 is rotatably mounted on a mounting base 39 fixed to the indoor side surface of the vertical stile 8. A gear 41 is fixed to a rotating shaft 40 connected to the base end of the second handle 19, and this gear 41 and a rack 42 fixed to the elevating plate 38 are meshed with each other.

Therefore, when the second handle 19 is rotated, the second handle connected to the second handle 19 via the rotating shaft 40, the gear 41, the rack 42, the elevating plate 38, and the pin 37 is rotated. The elevating member 20 moves up and down by an amount corresponding to the amount of rotation of the second handle 19.

Furthermore, in the illustrated embodiment, depending on the amount of operation of the second handle 19 provided on the indoor side of the vertical stile 8,
The opening angle of the window shoji 2 is adjustable, and the window shoji 2 can be completely opened by operating a first handle provided on the outdoor side of the vertical frame 5.

In order to configure the opening adjustment mechanism of this window shoji 2,

The inclined portion 23b continues from the tip of the straight body portion 23a so as to be bent toward the outdoors, and allows the straight body portion 23a and the outside of the connecting arm 22 to communicate with each other. or,
When the window sash 2 is rotated to the closed state and the horizontal stile 7 and the horizontal frame 4 are parallel to each other, the inclined portion 23b faces outdoors as it moves away from the straight main body portion 23a. Further, when the window sash 2 is left half open for ventilation (as indicated by the chain line a in FIG. 10), the inclined portion 23b and the horizontal stile 7 become parallel to each other.

Moreover, on the lower surface of the horizontal stile 7 of the window shoji 2, there are seventh to
A first horizontally moving member 24 as shown in FIG. 9 is attached so that it can freely move along the horizontal stile 7. One end of the first horizontally moving member 24 (the right end in FIGS. 7 and 9) and the lower end of the second elevating member 20 are
They are connected to each other by a first driving force transmitting device 25.

This first driving force transmitting device 25 has a hollow casing 26 bent at right angles at the middle portion, and a spring material, etc.
It is constructed by inserting a transmission member having rigidity and flexibility, and horizontally moves the first horizontally moving member 24 as the second elevating member 20 moves up and down.

In this way, the base end of the mounting plate 27 is attached to the other end (the left end in FIGS. 7 and 9) of the first horizontally moving member 24, which moves horizontally as the second elevating member 20 moves up and down. The binding is fixed. And this mounting plate 27
A pin 28 that can be freely engaged with the engagement groove 23 is suspended from the lower surface of the tip.

On the other hand, on the upper surface of the lower horizontal frame 4 constituting the lower side of the window frame 6, a second horizontally moving member 29 that moves horizontally along the horizontal frame 4 is provided. Then, the base end portion (the right end portion in FIGS. 7 and 9) of the second horizontally moving member 29 is connected to the second horizontally moving member 29 via the second driving force transmitting device 30.
It is coupled to the lower end of the first elevating member 11. This second power transmitting device 30 has the same structure as the first driving force transmitting device 25. Therefore,
As the first elevating member 11 moves up and down, the second horizontally moving member 29 moves horizontally along the horizontal frame 4.

The tip of the second horizontally moving member 29 (seventh,
A bent portion 31 is formed at the left end (in FIG. 9). The tip of this bent portion 31 (upper end in Fig. 9)
The hole 32 extends to the lower side of a long hole 32 formed in the support bracket 21 along the length of the horizontal frame 4. A pin 33 implanted on the upper surface of the tip of this bent portion 31 is loosely engaged with the elongated hole 32.

The connecting arm 22 is pivotally supported on the support bracket 21 by a pivot shaft 34 provided near the end of the elongated hole 32. The outer peripheral edge of the proximal end of the coupling arm 22 is formed into a semi-circular curved edge 35.
A notch 36 recessed toward the pivot 34 is formed in a part of the curved edge 35 . The pin 33 moves to one end of the elongated hole 32 (left end in FIGS. 7 and 9) when the second horizontally moving member 29 moves forward (leftward in FIGS. 7 and 9). ,
Enter into the notch 36.

In the emergency access window of the present invention configured as described above, when opening the closed window sash 2 for ventilation during normal times (when no fire has occurred), the window sash 2 must be opened. The second handle 19 provided on the indoor side of the vertical stile 8 is rotated by 90 degrees from the closed position.

In this way, as the second handle 19 rotates, the rotating shaft 40 and the gear 4
1. The second elevating member 20 connected via the rack 42, the elevating plate 38, and the pin 37 descends a little along the vertical frame 8, and the roller fixed to the inner surface of the second elevating member 20 The shaped abutting pieces 14, 14 are lowered.

When the second elevating member 20 descends in this way, the first elevating member 11 provided on the inner surface of the vertical frame 5 does not move up and down, and the cam block 13 fixed to the inner surface of the first elevating member 11, 13 doesn't move.

Therefore, the cam blocks 13, 13 fixed to the first elevating member 11 and the abutment pieces 14, 14 fixed to the second elevating member 20 move relative to each other in the vertical direction. Cam block 13, 13
The abutment between the abutment pieces 14 and 14 is removed. and,
The abutting pieces 14, 14 can be moved further indoors than the cam blocks 13, 13.

For this reason, the force that presses the outdoor side surfaces of the vertical and horizontal frames 8 and 7 that make up the window shoji 2 against the packing 44 (FIG. 9) attached to the vertical and horizontal frames 5 and 4 that make up the window frame 6 is released. At the same time, the window shoji 2 can be freely rotated in the opening direction about the hinge connecting the vertical frame 5 and the vertical stile 8 on the left side in FIG.

However, in this case, the first elevating member 1
1 does not move up or down, and the notch 36 at the base end of the connecting arm 22 and the pin 33 remain engaged with each other. For this reason, the connecting arm 22 only rotates to the state shown by the chain line in FIG.

Further, the pin 28, which moves horizontally as the second elevating member 20 descends, also moves only a little.
Therefore, as the window sash 2 moves in the opening direction, the horizontal frame 4 and the horizontal stile 7 rotate relative to each other, and the connecting arm 22 rotates within the range in which the pin 33 can move within the notch 36. Even when the pin 28 moves, the pin 28 will not come out of the engagement groove 23.

Therefore, the window sill 2 is in a half-open state with the horizontal frame 4 and the horizontal stile 7 still connected to each other by the connecting arm 22 (for example, as shown by the chain line a in FIG. 2 opens about 10 degrees to the wall) and can be used for indoor ventilation.

In order to clean the outdoor surface of the glass 9 constituting the window shoji 2, when the window shoji 2 is opened wide (for example, about 90 degrees) with respect to the wall surface, the second handle 1
Rotate 9 further 90 degrees (180 degrees based on the closed state).

When the second handle 19 is largely rotated in this way, the mounting plate 27 attached to the tip of the first horizontally moving member 24 is placed in the state shown by the solid line in FIG. state) to the state shown by the chain line in the figure. And this mounting plate 27
A pin 28 hanging down from the lower surface of the connecting arm 22 comes out of an engagement groove 23 formed at the tip of the connecting arm 22.

Therefore, the window shoji 2 can be opened wide toward the indoor side without being restricted by the connecting arms 22.

A known click mechanism is provided between the support bracket 21 and the connecting arm 22, which is comprised of a steel ball 43 pressed by a spring and a recess into which the steel ball 43 fits. This click mechanism is
It works when the window shoji 2 is half-opened as shown in FIG. Therefore, even when the window shoji 2 and the connecting arm 22 are uncoupled and only the window shoji 2 is rotated indoors, the connecting arm 22 remains in the position shown in FIG. 9 unless an external force is applied. The state shown in is maintained.

When closing the window shoji 2, the window shoji 2 is rotated in the closing direction and placed inside the window frame 6, contrary to the case of the above-mentioned opening operation. Thereafter, the second handle 19 is rotated in the opposite direction to the opening operation, and the second elevating member 2 provided on the outer surface of the vertical stile 8 is rotated.
0 is raised, and a roller-shaped abutment piece 14 attached to the outer surface of the second elevating member 20 and a cam block fixed to the inner surface of the first elevating member 11 provided on the inner surface of the vertical frame 5 are connected. 13 and collide with each other. As a result, the outdoor side surfaces of the vertical and horizontal frames 8 and 7 forming the window shoji 2 are pressed against the packing 44 attached to the vertical and horizontal frames 5 and 4 forming the window frame 6.

However, if you want to close the window shoji 2 again after opening it wide to clean the outdoor surface of the glass 9, first turn the second handle 19 widely (from the closed state). (rotated 180 degrees)
The window shoji 2 is then moved in the closing direction, leaving the window shoji 2 in a half-open state (the state indicated by the chain line a in FIG. 10).

By setting the window shoji 2 in a half-open state, the positional relationship between the mounting plate 27 at the tip of the first horizontally moving member 24 and the connecting arm 22 becomes the state shown by the chain line in FIG. 9. Therefore, from this state, rotate the second handle 19 slightly in the closing direction (until the angle with the closed state is about 90 degrees), and as shown by the solid line in FIG. Connect the hanging pin 28 to the connecting arm 2
2 into the engagement groove 23 formed at the tip.
The following operation is the same as when opening the window shoji 2 for ventilation.

In addition, in the event of a fire, when opening the closed window shoji 2 from outside for extinguishing work, the first handle provided on the outdoor side of the vertical frame 5 of the window frame 6 is operated. , the first elevating member 11 provided on the inner surface of the vertical frame 5 is raised along the vertical frame 5.

At this time, the second elevating member 20 provided on the outer surface of the vertical stile 8 constituting the window shoji 2 does not rise or fall. Therefore, as the first elevating member 11 rises, the cam blocks 13, 13 fixed to the inner surface of the first elevating member 11 and the roller-shaped rollers provided on the outer surface of the second elevating member 20 The abutting pieces 14, 14 are disengaged, and the abutting pieces 14, 14 are attached to the cam blocks 13, 1.
It is possible to move indoors more than 3.

At the same time, the second horizontally moving member 29 provided on the upper surface of the lower horizontal frame 4 moves to the right in FIGS. 7 and 9. Along with this movement, the pin 33 provided on the upper surface of the tip of the bent portion 31 at the tip of the second horizontally moving member 29 comes out from inside the notch 36 formed at the base end of the connecting arm 22. . As a result, the coupling arm 22 can freely rotate without being restricted in its rotation angle.

Therefore, the window shoji 2 can be opened wide without being restricted by the connecting arms 22.

In addition, the first handle provided on the outdoor side of the vertical frame 5 is
Similar to the second handle 19, it is also possible to use one with the structure shown in Figure 6, but it is used only in emergencies and does not require much operability or durability. Therefore, the linear movement of the handle is directly transmitted to the first elevating member 11, etc.
It is also possible to simplify the structure and make it smaller.

(Effects of the invention) Since the emergency entry window of the invention is configured and operates as described above, it is possible to enter indoors without using special equipment even when glass with wire mesh is used. When used as a fire entrance, important time is not wasted for fire extinguishing activities, and effective fire extinguishing and rescue operations can be carried out.

Furthermore, since there is no need to move moving members during the opening operation from the outdoor side or the opening operation from the indoor side, the opening operation from the outdoor side can be performed with a small force in the same way as the opening operation from the indoor side. Therefore, fire extinguishing work can be smoothly carried out in a timely manner.
