Description

[Detailed description of the invention] [Field of industrial application] This invention relates to a ventilation opening formed indoors, and more specifically, a ventilation opening that can be opened and closed by reversing and replacing a removable louver. It is related to.

[Prior Art] Generally, a ventilation opening is formed in a room, such as a sunroom. Specifically, it consists of an aluminum frame that is attached to an opening formed in the sunroom floor, a sliding air breather that is positioned from the outside at the bottom of this aluminum frame, and a wooden lattice that fits into the aluminum frame. ing. When ventilation was desired, the lattice was removed from the aluminum frame, the air breather was slid open by hand, and then the lattice was fitted into the aluminum frame again to let outside air from under the floor into the sunroom. .

As another conventional example, there is a ventilation opening that is constructed of a frame that is attached to an opening formed in a floor, a wooden lattice that is replaceably attached to the opening of the frame, and a blind lid. When ventilating, the lid was removed from the frame and a lattice was attached to let outside air in. When ventilation was not required, the lattice was removed from the frame and the lid was placed on top.

[Problem that the invention attempts to solve]

However, the conventional technology has the following problems.

B. The former conventional technology has problems in that it requires a large number of parts, increases cost, and requires troublesome ventilation operations.

(b) The latter conventional technology involves replacing the lattice and the lid by removing the lid and attaching the lattice to the frame when ventilation is required, and removing the lattice from the frame and attaching the lid when ventilation is not required. There is a problem that the operation is cumbersome, and it takes time and effort to store and sometimes search for the removed grid or lid.

C. In both the former and latter conventional techniques, the grid is mounted in an erected manner on the grid mounting part formed on the periphery of the frame, so the grid is not strong enough to withstand loads such as stepping on the grid. There was a problem in that it was necessary to hold the lattice, and the cost of making the lattice robust was high.

This invention solves the above-mentioned problems, and aims to provide a ventilation opening that is simple in structure, has a small number of parts, can reduce costs, and is easy to operate.

[Means for solving problems]

In order to solve the above-mentioned problems, this invention includes a frame body in which long hole-shaped ventilation holes are formed in the bottom at equal intervals in parallel, and is attached to a ventilation opening opened in the indoor floor; Arranged at intervals that close the mouth,
A louver that is placed on the bottom of the frame and has blades forming contact surfaces on both front and back sides is removably fitted to the frame, and further, at least one of the contact surfaces of the blades is provided with the ventilation hole. A ventilation hole is formed on a contact surface placed on the bottom of the frame body to be opened, and can be opened and closed depending on the direction of the contact surface of the blade by reversing the top and bottom of the louver and/or the front and back directions. It is something.

[Effect]

Since the vent according to this invention was constructed as described above, the louver fitted into the frame was removed.
By flipping it upside down and/or front and back and fitting it into the frame again, the contact surfaces of the blades can be moved from the vent position at the bottom of the frame where they are parallel and evenly spaced to the bottom position away from the vent, or from the vent position to the bottom position away from the vent. Since the avoided bottom position is replaced by the vent position, ventilation is performed by freely displacing the vent from the closed state to the open state or from the open state to the closed state.

〔Example〕

An embodiment of this invention will be described based on the drawings.
Figure 1 of the drawings is a partially cutaway perspective view of the ventilation port, Figure 2 is a cross-sectional view of the ventilation port, Figure 3 is a cross-sectional view of the ventilation port with the louver in Figure 2 reversed, and Figure 4 is a cross-sectional view of the ventilation port. It is a top view of a frame.

Ventilation port A is configured as follows. That is, a frame body 1 with a bottom is attached to a ventilation opening (not shown) formed in the indoor floor part B of the sunroom, and a louver that can be fitted and removed from this frame body 1 and placed directly on the bottom part 2 of the frame body. It consists of 6. The frame 1 is formed by bending an aluminum plate to have a certain depth, and forms a rectangular bottom 2, as well as flange-shaped attachment portions 3 on the four upper sides of the frame 1. Furthermore, long hole-shaped ventilation holes 2a are bored in the bottom part 2 at regular intervals in parallel, so that outside air can be taken in from under the floor. A mounting hole is formed for mounting on the A steel net 5 is attached to the back side of the frame bottom 2 by spot welding to prevent insects from entering from under the floor.

The louver 6 has upper, lower, left and right frames 7 in plan view,
A plurality of vanes 8 are arranged inside these frames 7. This louver 6 is formed to have an external dimension that fits into the frame 1, and further, when placed on the frame bottom 2, the upper surface position of the louver 6 is approximately 1 mm lower than the height of the frame flange 3. to prevent feet from getting caught. The entire surface of the louver 6 is placed linearly on the frame bottom 2, and the load from above is applied entirely to the frame 1, so the louver 6 itself has the same strength as before. There's no need.

The wing plate 8 has ventilation holes 2 arranged on the bottom part 2 of the frame body.
They are installed so that they are located opposite each other at intervals of a.
The slats 8 are attached by applying an adhesive to both end faces in the longitudinal direction of each slat 8 to provide a tack stop that penetrates the slats 8 from the outside of the stile 7. The shape of the wing plate 8 is formed into a trapezoidal pentagon with one corner of a quadrilateral cut out in cross-sectional view, and in FIG.
Lift up and remove the louver 6 when it is in the position avoiding a, and turn it upside down 180 degrees on a flat surface, and the third
As shown in the figure, the contact surface 8a of the blade 8 is placed at a position where the vent hole 2a of the bottom portion 2 is closed. In other words, the frames 7a and 7 in the vertical positional relationship
b is the second one by flipping it 180° on the plane.
The upper stile 7a in the figure is located at the lower side in FIG. 3, and the lower stile 7b in FIG. 2 is located at the upper side in FIG. 3. As a result, the vent 2a
changes from an open state to a closed state, and the intake of outside air is interrupted, resulting in no ventilation.

When ventilation is desired, the top and bottom of the louver 6
If the 180° inversion operation is performed in the opposite direction, the louver 6 will move from the state shown in FIG. 3 to the state shown in FIG. Become.

Although not shown, the louver 6 can be removed from the frame 1 and turned over 180° to freely open and close the vent 2a. That is,
Since the upper surface of the blade 8 in FIG. 2 faces downward by turning the front and back 180 degrees and is placed on the frame bottom 2, the contact surface 8a of each blade 8 is connected to the frame ventilation hole. 2a is in a closed state.

Next, other embodiments of the blade shape may be shown in FIGS. 5 and 6. That is, as shown in FIG. 5 as a second embodiment, the blades 9 are formed to have a hexagonal cross section and are arranged in a frame with the upper and lower surfaces parallel to each other. As a third embodiment, as shown in FIG. 6, the wing plate 10 may be formed into an L-shape in cross section.
In the second and third embodiments described above, even if the louver 6 is turned over 180° vertically or front and back as in the first embodiment, the contact surfaces of the respective blades 9 and 10 remain on the frame bottom 2. vent 2a, or at the bottom 2 avoiding the vent 2a.
It can be opened and closed freely.

Note that the shape of the louver of the louver is not limited to those of the first to third embodiments described above, and one side of the louver closes the frame vent with the contact surface of the louver before being turned over. After flipping the louver 180 degrees vertically and/or front and back, it should be shaped so that the bottom side is located at the bottom of the frame, avoiding the position of the frame vent with the contact surface of the wing. It is fine as long as it is something. A structure for ventilating the inside of a sunroom to make it more comfortable to live in using the ventilation opening configured as described above will be explained using an example adopted in the ventilation mechanism shown in FIG. 7. In the sunroom C, a ventilation opening A is formed in the floor part B, and a sliding opening/closing type exhaust opening 11 is located on the ceiling side. Outdoors, a cool rail 12 is buried underground to introduce outside air to obtain cold air in the summer or to warm the outside air in the winter. A pipe 13 for heat exchange is connected to the cool rack 12 toward the ground, and its tip is connected to the ventilation port A. A suction fan 14 is installed below the ventilation port A in the pipe 13. Without providing this fan 14, the outside air may be introduced into the sunroom C by the natural upward movement of the air inside the pipes due to the temperature difference between the ground and the underground, using a difference in height between the pipes.

By configuring the ventilation mechanism as described above,
In the summer, if you open the vent A louver, the outside air taken into Cool Rael 12 will flow through fan 14.
While being attracted by the suction action of the air, the air is cooled in the pipe 13 and taken into the sunroom C through the ventilation opening A as cold air. If the exhaust port 11 is left open, the warm air inside the sunroom C will be exhausted and the room will be made comfortable with cool air. In the winter, if the cool rack 12 is closed so that outside air cannot be taken in, the air inside the pipe 13 will be warmed by underground heat, and the fan 14 will suck in warm air from the exhaust port A to the sunroom C. installed inside the room to make the room more comfortable.

[Effect of idea]

Since this invention is constructed as described above, it has the following effects.

(b) Since the only constituent members of the ventilation hole are the frame body in which the elongated hole-shaped ventilation hole is formed and the louver, the number of parts is small, and the manufacturing process is not labor-intensive, resulting in cost reduction.

The ventilation opening can be opened and closed by simply removing the garary from the frame and turning it upside down and/or front and back, making ventilation operations easy and hassle-free.

Since the entire surface of the louver is placed on the bottom of the frame, even if a person steps on the louver and places a load on it, the frame can absorb that load, and the louver retains the same strength as before. There is no need to do this, and costs can be reduced.
