Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention is provided with a raising and lowering door housed inside the door body,
The present invention relates to a ventilation door that opens and closes a ventilation and daylighting section that is opened in a door body by these raising and lowering doors and moves the raising and lowering doors up and down by an operating rod.

(Prior Art) A conventional ventilation door is one in which an insect screen is stretched over the entire outdoor side of the door body, and a pair of raising and lowering doors is provided on the indoor side thereof, and these raising and lowering doors are moved up or down. As a result, a mechanism for ventilating from the opening formed inside the door body is provided. However, since the raising and lowering door is exposed to the outside and can be easily raised and lowered, there is a problem in terms of crime prevention and a problem that the appearance is not good.

(Technical problem of the invention) The technical problem of the present invention is to solve the above-mentioned problems and to provide a ventilation door which has a ventilation function and a daylighting function and is excellent in crime prevention and operability.

(Means for Solving the Problems) In order to solve the above problems, the ventilation door according to the present invention has an opening formed in either or both of an upper portion and a lower portion of a panel provided on an indoor side and an outdoor side of a door body. The ventilation and daylighting section is opened and closed by a raising and lowering door that is housed in a sliding manner between the indoor and outdoor panels, and vertical holes are formed vertically through the left and right sides of the indoor panel of the door body. The raising and lowering door is provided with an operating rod formed by projecting rods protruding from both left and right sides of the raising and lowering door through the elongated hole and projecting to the indoor side, and integrally connecting left and right projecting ends of the rod. It is characterized by

(Operation and Effect of the Invention) In the above-described configuration, the ventilation and daylighting portion of the door body can be opened and closed by the vertical movement of the raising and lowering door, so that the door can be provided with ventilation and daylighting functions. Moreover, when opening and closing the ventilation and daylighting section, the operating rod that protrudes to the indoor side is moved up and down, and the operating rod cannot be operated from the outside. Since it is housed between the doors and is not exposed to the outside, the security of the ventilation door is improved and the appearance is improved. Further, since the operating rod is formed by integrally connecting the left and right rod bodies,
It can be operated with one hand, making it easy to operate the door.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In the figure, reference symbol A indicates a ventilation door. This ventilation door
A door main body 4 provided with indoor / outdoor panels 2 and 3 and a pair of doors housed between the indoor / outdoor panels 2 and 3, which are provided in a door opening of a building body so as to be rotatable and openable / closable by a hinge portion. It is composed of the raising and lowering doors 5 and 6.

The door body 4 has a left-right vertical frame 7, 7 and upper and lower horizontal frames 8, 8 in a rectangular frame, and a plurality of horizontal frames are provided on the outdoor side and the indoor side of these vertical frames 7, 7 and horizontal frames 8, 8, respectively. Bones 9, 9,
The indoor panel 2 and the outdoor panel 3 are provided so as to face each other with a space interposed therebetween, and grid-like ventilation and daylighting portions 10 and 11 are provided on the upper and lower portions of the indoor and outdoor panels 2 and 3, respectively. Blind portions 12 are formed in the middle portion, and elongated holes 13 are formed in the up-down direction on the left and right sides of the indoor panel 2 as shown in FIG. In addition, the upper ventilation and daylighting section 10
The ratio of the vertical dimensions of the blind portion 12 in the middle portion and the ventilation / light collecting portion 11 in the lower portion is set to approximately 1: 2: 1. 22 is a pull tab of the door body 4.

Next, two sliding grooves 14 and 14 are arranged side by side along the inner surfaces of the left and right vertical frames 7 and 7 of the door body 4 inside and outside, respectively. , 6 are stored so that they can move up and down.

A transparent plate portion 15 and an insect screen portion 16 are provided on the upper and lower portions of the door 5 on the indoor side, respectively. The translucent plate portion 15 is formed slightly larger than the blind portion 12, and the insect screen portion 16 is formed in a size corresponding to the ventilation and daylighting portions 10 and 11.

On the other hand, the door 6 on the outdoor side is the door 5 above.
The transparent plate portion 15 and the insect screen portion 16 having the same size as the above are provided on the opposite sides in the vertical direction.

A pinion 18 is rotatably provided vertically in the sliding grooves 14, 14 of the left and right vertical frames 7, 7 of the door body 4, and a rack 19 is provided on the left and right vertical frames 20, 20 of the two doors 5, 6. Is provided. As shown in FIG. 6, the racks 19 of both doors face each other and face each other, and the pinion 18 is arranged so as to mesh between the racks 19.

Next, an operating rod 17 is provided on the indoor door 2 facing the indoor panel 2. The operating rods 17 are rods 17a, 17a projecting from the left and right sides of the indoor doors 5, 6, respectively.
Is formed by penetrating through the long holes 13 on both left and right sides of the indoor panel 2 to project to the indoor side, and the projecting ends of these rods 17a, 17a are integrally connected via a handle 17b. .

In the above configuration, the ventilation door A can open and close the door opening by rotating it with the pull tab 22, and by raising or lowering the operating rod 17, the indoor raising / lowering door 5 also slides upward or downward. To do. At this time, the pinion 18 meshing with the rack 19 provided on the raising / lowering door 5 rotates, so that the rack 19 of the outdoor raising / lowering door 6 that meshes with the pinion 18 is driven. It slides in the opposite direction in conjunction with the door 5 of.

Therefore, as shown in FIG. 1 (a), the upper and lower ventilation and daylighting sections 10 and 11 of the door body 4 are connected to the translucent plate section 1 of the two doors 5 and 6, respectively.
When 5 and 15 correspond to the ventilation and daylighting sections 10 and 11 in the closed state, the translucent plate section is moved from the ventilation and daylighting sections 10 and 11.
You can get the daylight by 15, 15. On the other hand, when the operating rod 17 is raised, the indoor raising / lowering door 55 slides upward, and the other raising / lowering door 6 slides downward, so that FIG.
As described above, the insect net parts 16, 16 of the doors 5, 6 are exposed at the positions corresponding to the ventilation and daylighting parts 10, 11 of the door body 4, and the ventilation and daylighting parts 10, 11 are opened. Therefore, even if the door is not opened and operated, the invasion of insects can be prevented and ventilation can be obtained. When the operating rod 17 is further lowered, the ventilation and daylighting section 10,
11 is closed again, and the insect screen 16 is a blind part of the door body 4.
It goes inside 12 and is hidden from the outside.

As described above, since the ventilation and daylighting portions 10 and 11 of the door body 4 can be opened and closed by the raising and lowering doors 5 and 6, the door can be provided with ventilation and daylighting functions. Moreover, when opening and closing the ventilation and daylighting sections 10 and 11, the operation rod 17 protruding toward the indoor side is moved up and down.
In addition to not being able to operate 17, the doors 5 and 6 are housed between the indoor and outdoor panels 2 and 3 of the door body 4 and are not exposed to the outside, so the security of the ventilation door is improved and the appearance is good. Becomes Further, since the operating rod 17 is formed by integrally connecting the left and right rods 17a, 17a, it can be operated with one hand, and the raising and lowering doors 5, 6 can be operated easily.
