Description

  The present invention relates to an entrance door of an apartment house such as an apartment or an apartment.

  Conventionally, the entrance doors of apartment buildings have not been provided with natural openings by providing openings such as louvers for crime prevention and fire prevention, but natural ventilation is performed from the balcony side opposite the entrance. For this reason, the dwelling unit is in a bag state, and it is not possible to obtain the refreshingness that the wind in the middle of summer or spring and autumn passes. When natural ventilation is required, packing is kept under the entrance door, and the entrance door is opened halfway for natural ventilation. However, there was a problem that people passing through the corridors could look into the dwelling unit. There are several proposals for introducing wind into the dwelling unit, and one of them is a ventilation door. This is because when two shoji screens are built up and down in the door and an opening is provided, the upper shoji screen moves down, the lower shoji screen moves up, and the shoji screen moves up and down. It is.

Moreover, the door which can be ventilated and daylighting of Unexamined-Japanese-Patent No. 2004-11335 provides a slide space in a door main body, and the opening which penetrates the said slide space to the indoor outdoor direction in the center part of the width direction of the door main body. And a small door having a daylighting portion and a ventilation portion having substantially the same width as the opening, and is slidably provided.

  The conventional ventilating doors that incorporate the two above-mentioned shojis above and below are doors that are provided at the door, and the part where the shojis moved opens, and the upper and lower shojis overlap in the middle when fully open, so the shojis are stored Protrudes from the door body. For this reason, only a lever handle lock with a long cylinder can be used, and it is difficult to attach a door chain or door guard, and since it can be easily opened from the outside, there is a problem in terms of crime prevention, and there is a problem in using it as a front door.

  A door that allows ventilation and lighting is provided with a slide space in the door body, and a small door having a lighting part and a ventilation part is slidably provided in the slide space. Since the door is built in the door, the lock is attached to avoid the sliding small door, so the position of the lock is limited, it is difficult to attach the door chain and door guard, and it can be easily opened from the outside, so it is also crime prevention There are problems, and it is difficult to ensure the performance as a fire prevention equipment, and there is a problem in using it as an entrance door.

  The entrance door with a small door for ventilation is provided with a ventilation grill on the sleeve wall panel, and the ventilation grill is configured to drop the fire damper in the event of a fire and shut it off from the small door. A grill will be provided, and there is a risk that dust will be trapped and the effect of ventilation cannot be expected. Furthermore, because the sleeve wall panels are arranged side by side, the sleeve wall panels will affect the layout around the entrance and restrict the floor plan around the entrance of apartments and condominiums, etc. There is.

  In view of the above, the present invention provides a refreshing effect that the wind in the middle of summer or spring and autumn passes even if the entrance door is locked, prevents insects from entering even through the wind, shields the line of sight, fires An object is to provide an entrance door that sometimes functions as a specific fire prevention equipment and ensures crime prevention performance.

  According to the first aspect of the present invention, a ventilation panel 2 for ventilation is provided on the door body 1 and an outer small door 3 urged so as to be always closed by an auto hinge is provided on the outside of the ventilation panel 2 so as to be openable and closable. The latch 4 that locks with the small door 3 opened is linked to the smoke sensor or the combined heat and smoke sensor, or the latch 4 of the outer small door 3 is released in the event of a fire in conjunction with the thermal fuse. The small door 3 is closed and the space between the ventilation panels 2 is blocked, and the inner small door 5 is provided on the indoor side of the ventilation panel 2 so as to be openable and closable. This is a front door that can be opened and closed from the indoor side to adjust the ventilation rate of the ventilation panel 2 and to close the ventilation panel.

  The door main body 1 is a steel flash door in which an iron plate having a thickness of 0.5 mm or more is pasted on both sides of a steel frame or a press door having a thickness of 1.5 mm or more. The thickness of the door is usually 40 mm. The outer small door 3, the ventilation panel 2, and the inner small door 5 are incorporated in the door thickness. The outer small door 3 is also a steel flush door or press door similar to the above. In order to ensure the fire prevention performance of the specific fire prevention equipment of the ventilation panel portion, the outer small door 3 is a 180 degree open single door incorporating an auto hinge and is linked to a known smoke sensor or a combined heat smoke sensor, Or, it will be a self-closing fire door linked to a thermal fuse. The inner small door 5 is a steel flush door or press door similar to the above, but may be made of aluminum. The inner small door 5 opens and closes in order to adjust the air flow rate of the ventilation panel from the room at the opening angle, so it may be a hinged door, but a folding door is optimal for reducing the occupied area when the door is opened. is there. Note that the door thickness of the door body 1 is not limited to 40 mm, and the door thickness may be changed by accommodating the outer small door 3, the ventilation panel 2, and the inner small door 5. This ventilation panel 2 has an outer door 3 on the outdoor side and an inner door 5 on the indoor side, ensuring specific fire prevention equipment and crime prevention performance, allowing wind to pass but preventing insects from entering and shielding the line of sight. Has the effect of

  There are many standards for smoke detectors and thermal smoke detectors, and those that can be incorporated into the outer small door 3 are appropriately selected. The sensor detects fire smoke or flame and converts it into an electrical signal. This electrical signal operates on the electromagnet charged in the latch 4 and the claw that locks the outer door 3 is released. The outer door 3 suspended from the hinge acts to close. Many standards for thermal fuses are commercially available, and those that can be incorporated into the outer small door 3 are selected as appropriate. This thermal fuse is melted by heat at the time of fire, for example, melted at a melting point of 72 degrees, the spring works, the latch that locks the outer small door 3 is released, and the outer small door suspended by the auto hinge 3 has the effect of closing.

  According to the second aspect of the present invention, the support plate 12 is interposed between the two punching metals 11 so that the size is smaller than the thickness of the door. The dimension to be set is determined by the fit of the outer small door 3, the ventilation panel 2, and the inner small door 5, but 20 mm is usually adopted. The punching metal 11 is a commercially available aluminum plate, stainless steel plate, or steel plate, the plate thickness is 1.0 mm to 1.6 mm, the holes 13 are squares of 20 mm × 20 mm and the interval is 40 mm, or the circle is 20 mm in diameter and the interval is 40 mm. However, the shape, size, and spacing of the holes are not limited to this, and may be any shape such as a rectangle, an ellipse, a triangle, a cross, or a star. The size of the hole 13 is made the same and the position of the hole 13 is shifted so as to block the line of sight from the hole 13 so that the passing air volume of the punching metal 11 on the outdoor side and the punching metal 11 on the indoor side are the same. The ventilation panel 2 is an indoor punching metal 11 provided with an insect net 14, which allows the wind to pass but prevents insects from entering and shields the line of sight.

  Further, the holes 13 of the punching metal 11 on the indoor side may be made smaller than the punching metal 11 on the outdoor side, the interval may be made fine, and the size of the holes 13 per unit area may be made the same, so that the air flow rate is the same. In this case, the size and interval of the holes 13 in the punching metal 11 on the outdoor side and the punching metal 11 on the indoor side should not be made an integral multiple. By doing so, the position of the hole 13 is shifted and the hole 13 of the punching metal 11 on the indoor side is small, so that the effect of wrinkles is exhibited. That is, when the room is darker than the outside, an effect that the room cannot be seen from the outside even though the room can be seen from outside the room appears. The ventilation panel 2 is provided with an insect screen 14 on the indoor side of the punching metal 11 and has the effect of blocking the line of sight by preventing the invasion of insects while allowing the wind to pass therethrough.

  The support plate 12 has an effect of setting the interval between the two punching metals 11 with the support plate 12 interposed therebetween, and also has an effect of a reinforcing material for ensuring the strength of the ventilation panel 2. The insect net 14 prevents insects from entering, and various types of standards such as stainless steel and polypropylene are commercially available. 16 to 24 meshes are used as the mesh standards.

A ventilation panel 2 is provided with a net 14. The thickness of the ventilation panel 2 is determined by the size of the outer small door 3, the ventilation panel 2, and the inner small door 5. Normally, 20mm is adopted, and if the cell angle rises 45 degrees indoors, the cell spacing Becomes 20 mm, and the line of sight can be blocked. The angle is not limited to 45 degrees, but is determined by the thickness d of the honeycomb core 15 and the interval p. When the angle is decreased, the interval p is also decreased and the line of sight is blocked. The honeycomb core 15 is an aluminum plate, a stainless steel plate, or a steel plate, and a thin plate having a thickness of 0.4 mm to 1.2 mm is used, and the shape of the cell may be any of hexagonal, square, circular, corrugated, and the like. A ventilation panel 2 is provided with an insect screen 14 attached to the indoor surface of the honeycomb core 15 and has the effect of blocking the line of sight by preventing the invasion of insects but allowing the wind to pass therethrough as described above.

  An outside small door 3 energized so as to be always closed by an auto hinge is provided on the outside of the ventilation panel 2 so as to be openable and closable. In conjunction with a thermal sensor or in conjunction with a thermal fuse, the latch 4 of the outer small door 3 is released in the event of a fire, the outer small door 3 is closed, and the ventilation panel 2 is shut off. It has the effect of ensuring the performance of specific fire prevention equipment. By making the outer small door 3 a door that opens 180 degrees, there is an effect that the passage of the corridor is not obstructed even in the opened state. With the configuration in which the inside small door 5 is provided on the indoor side of the ventilation panel 2, there is an effect that the ventilation amount can be adjusted and the ventilation panel portion can be locked with the door body 1 locked. Further, by making the inner small door 5 a folding door, there is an effect that the occupied area when opened can be reduced and the entrance area can be used widely.

  By configuring the ventilation panel 2 with the two punching metals 11 and the insect net 14, each can be selected and configured from commercially available standard products, so that the cost can be reduced. The support plate 12 has an effect of setting the interval of the punching metal 11 and ensuring the strength of the ventilation panel 2. By shifting the position of the hole 13 of the punching metal 11, the wind passes but has the effect of blocking the line of sight. When the hole 13 of the punching metal 11 on the indoor side is made smaller than the hole 13 of the punching metal 11 on the outdoor side, there is an effect that when the room is darker than the outside, the room can be seen from the outside, but the room cannot be seen from the outside.

  By setting an angle to shield the line of sight from commercially available honeycomb cores 15 of various standards and cutting them diagonally with the required width, an angled honeycomb core 15 can be formed, and this is used as the ventilation panel 2, so the cost is low. There is an effect that can be set small. Further, since ventilation can be performed with the entrance door closed, a comfortable environment can be obtained without operating the air conditioner in the middle of spring and autumn, so that the energy saving effect is the same as described above.
