Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a ventilation door having ventilation portions at the upper and lower portions of a door body for performing indoor and outdoor ventilation.

[Prior Art and Problems to be Solved] A conventional ventilation door has ventilation portions separated from each other at an upper portion and a lower portion of the door body, and a raising / lowering shoji is provided corresponding to each ventilation portion to open and close the door. There is something to do.

In the prior art, in order to communicate the lifting and lowering shoji provided separately in the vertical direction, a wire is used to interlock the two lifting and lowering shojis via a plurality of pulleys.

However, in the interlocking mechanism using the wire, there is a problem that slippage occurs between the wire and the pulley, or the wire stretches, so that stable interlocking cannot be performed. Further, the interlocking mechanism using a chain has a large size, although it does not slip, and it is difficult to incorporate it in the door body.

The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to ensure reliable and smooth interlocking between the lifting and lowering shoji.

[Means for Solving the Problems] The present invention provides a ventilation door having ventilation parts at the upper and lower parts of a door body, in which upper and lower doors for opening and closing the ventilation part are respectively installed at the upper and lower parts of the door body. , These upper and lower lifting / lowering doors are arranged in the same plane along the upper / lower longitudinal direction of the door body, and racks are provided along the both side surfaces of the upper / lower lifting / lowering doors and mesh with the respective racks. Interlocking the upper and lower shoji doors by engaging with the above-mentioned upper and lower hoisting shoji doors, which are vertically movable on both sides of the upper and lower hoisting shoji doors, and meshing with the upper and lower pinion gears that mesh with the rack of the hoisting and lower shoji doors. It is configured by providing a rack.

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

FIG. 1 is a front view of the ventilation door of the present invention seen from the outside, and FIG.
(A), (b) is the front view seen from the indoor side, FIG. 3 is the sectional view on the AA line of FIG.

In each of the above figures, the ventilation door of the present invention comprises a door body 1 having a large number of ventilation holes 8a, which are ventilation portions, in the upper and lower portions thereof, and raising and lowering shoji 10, 10 for opening and closing the upper and lower ventilation holes 8a. .

The door body 1 includes an outer frame 2 formed by vertically and horizontally connecting frames, an inner frame 3 framed inside the outer frame 2, and the outer frame 2 and the inner frame 3
It has two front and back surface panels 8 and 9 provided in a space surrounded by. The ventilation hole 8a is the surface panel 8 on the outdoor side.
Are provided on the upper and lower parts of the. Further, the front surface panel 9 on the indoor side is provided only in the center of the space surrounded by the inner frame 3, and the upper and lower portions corresponding to the ventilation holes 8a are opened.

The inside of the upper door body 1 is divided into two upper and lower parts by a middle bar 6,
Up and down shoji 10,10 are stored in each. That is, as shown in each drawing, two lifting and lowering shojis 10 are arranged in the same plane along the upper and lower longitudinal directions of the door 1.

The raising and lowering shoji 10 is guided on both sides by the left and right inner frames 3, 3 and moves up and down in the door body 1 to open or close the ventilation hole 8a. In addition, 10a is an airtight material, which is provided around the outdoor surface side of the lifting / lowering shoji 10, and the ventilation hole 8a is hermetically closed when the shoji is closed.

The raising and lowering shoji 10 has a glass plate in its frame,
Even when the ventilation holes 8a are closed, daylight can be obtained.
Reference numeral 4 denotes a roll screen door, which is pulled up to the front surface of the ventilation hole 8a when the lifting / lowering shoji 10 is opened by fixing the end portion to the frame of the hoisting / shock shovel 10.

FIGS. 4 and 5 show BB line and C- line of FIG. 1, respectively.
It is a C line sectional view.

As shown in each of the above figures, racks 13 are provided on the vertical frames of the two lifting and lowering shojis 10 along both side surfaces thereof. On the other hand, the left and right inner frames 3, 3 of the door body 1 are provided with pinions 11, 12 corresponding to the racks 13 and meshing with the racks 13. Therefore, the lifting / lowering shoji 10 moves up and down while being guided by the pinions 11 and 12 on both sides. The lower pinion 12 is composed of an inner first pinion 12a and an outer second pinion 12b.

An interlocking rack 15 is vertically movably housed in the left and right inner frames 3,3. This interlocking rack 15 has its inner flanks, the upper pinion 11 at the top and the second pinion at the bottom.
It meshes with 12b respectively. Therefore, when the lower lifting / lowering shovel 10 is lowered from the state shown in FIG. 2 (a), the first pinion 12a meshing with the rack 13 rotates, and the interlocking rack 1
The second pinion 12b that meshes with the 5 is rotated, so that the interlocking rack 15 moves downward along the inner frame 3. Then, by moving the interlocking rack 15, the upper pinion that meshes with this
11 rotates and raises the lifting and lowering shoji 10. As a result, as shown in FIG. 2 (b), the upper and lower ventilation holes 8a are closed by the lifting and lowering shoji 10,10.

On the contrary, when ventilation is performed by opening the ventilation hole 8a, if the lower lifting / lowering door 10 is lifted, the upper lifting / lowering door 10 is lowered via the interlocking rack 15, and the upper and lower ventilation holes 8a are opened. Becomes

In the embodiment, the interlocking rack 15 is fixed at an arbitrary position by meshing with a shoji stopper (not shown) provided on the middle crosspiece, so that the lifting and lowering shoji 10, 10 do not move up or down at any position. So that it is fixed.

The outer frame 2, the inner frame 3, the lifting and lowering shoji 10, the middle crosspiece 6 and the like are made of an extruded aluminum material, and the front panels 8 and 9 are made of an aluminum panel body.

In the embodiment, since the second pinion 12b is provided, the both lifting and lowering shoji 10,10 are configured to move in the opposite directions. However, without providing the second pinion 12b, both the lifting and lowering shoji 10,10 are provided. Can also be moved in the same direction.

Further, as in the embodiment, the ventilation part may not be composed of a large number of ventilation holes 8a, but may be a complete opening over the entire upper or lower part of the door body, and this opening may be opened and closed by the shoji 10, 10. .

[Effects of the Invention] As described above, according to the present invention, the force applied to the lifting and lowering shoji on the operating side remains unchanged by interlocking the upper and lower lifting and lowering shojis via the pinion and the interlocking rack provided on both sides of the lifting and lowering shoji. The effect is that it is transmitted to the other lifting / lowering shoji, and both lifting / lowering shoji separated reliably and smoothly can be interlocked. Further, according to the present invention, since the upper and lower lifting / lowering shoji are arranged in the same plane along the longitudinal direction of the door body and the racks are provided along both side surfaces of the lifting / lowering shoji, the shoji is superposed in the expected direction. Because the door is thin, the shoji can be held from inside and outside without any gaps, and by supporting the shoji from both sides, not inside and outside, there is no turning force in and out of the shoji. You can always open and close smoothly.

Further, according to the present invention, the upper and lower hoisting and sliding doors are arranged on the same plane along the upper and lower longitudinal directions of the door body, and the racks are provided along both side surfaces of these hoisting and sliding doors. By disposing them in the attaching direction, it is possible to prevent these meshing members from being compressed by the force that the shoji body receives due to wind or the like, and it is possible to obtain a smoother opening / closing operation.
