Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a ventilation register used for indoor ventilation.

(Conventional technology) Conventionally, for example, in apartment complexes, in order to ventilate (not forced) living rooms, ventilation holes were provided in the upper part of the wall next to the window sills, and a cylinder was inserted into this ventilation hole. A ventilation hood is attached to the outer end of the cylinder, exposing it to the outdoor wall, and a ventilation register is attached to the inner end, exposing it to the indoor wall. This ventilation register has an external panel with a trapezoidal cross section with numerous ventilation holes on the front of the mounting tube that is inserted into the cylinder, and a rotary opening/closing plate is installed inside this external panel. be. The way to use it is to operate the knob in the center of the front of the exterior pane to rotate the rotary opening/closing plate, open the ventilation holes on the exterior pane, and circulate air from the front of the exterior pane to ventilate the room. When not in use or when ventilation is temporarily interrupted, turn the rotary opening/closing plate to the closed position to close the ventilation hole.

(Problem to be solved by the invention) In apartment complexes, curtain rails generally extend to the side of the window sills, and for this reason, the curtains constantly cover the front of the outside of the ventilation register. Moreover, in the conventional example, air circulation is performed from the front (front) of the outside. For this reason, air circulation was obstructed by the curtain, making it difficult to provide sufficient ventilation. Therefore, if the curtain is thin and white, such as a lace curtain, the air blowing out from the ventilation register acts like a filter in front of the ventilation hole, and the curtain can be damaged by long-term use. There was also the problem of getting it dirty. Furthermore, due to long-term use, dirt had accumulated around the ventilation holes in front of the ventilation register, and this dirt could be seen directly from the front, spoiling the aesthetics of the room.

The purpose of the present invention is to provide sufficient ventilation even when the front of the ventilation register is covered with a curtain, and to prevent the curtain from becoming dirty and the aesthetics of the room to be maintained. Another object of the present invention is to enable smooth ventilation operations even if an obstacle is located in front of the ventilation register.

(Means for solving the problem) The present invention includes a mounting frame provided with a ventilation opening,
A front cover is attached to the front of the mounting frame with the shaft as the center of rotation, and a front cover that covers the ventilation opening is connected to the rear of the mounting frame and inserted into the ventilation hole opened in the wall. and a regulating means for positioning the front cover at a position where the ventilation opening is opened and a position where the ventilation opening is closed. The front cover has a substantially L-shaped side cross section, and the upper side of the front cover is the attachment portion to the attachment frame. In the open position of the front lid, the front plate portion of the front lid is set in a substantially hanging state.

(Function) By swinging the front cover back and forth, the ventilation opening is opened and closed, and the front cover is always positioned in front of the ventilation opening, creating a gap for indoor and outdoor air to circulate when opened. is ensured, and air circulation is not obstructed by curtains, etc. Air flows in and out of the room through the gap, and when the front cover is opened, a portion of the air from the ventilation opening hits the inner surface of the front plate and flows downward.

(Example) A first example of the present invention will be described with reference to FIGS. 1 to 5.

1 to 3, the ventilation register is provided with a front cover 2 at the front (left side in FIG. 1) and a mounting cylinder 3 at the rear of a support frame 1, which is a mounting frame.

The support frame 1 is formed into a rectangular shape in the front, has a ventilation hole 11 in the center, and has approximately square bearing plates 12 protruding from both sides of the upper part of the front (front).
A reinforcing plate 121 connects both bearing plates. Each bearing plate 12 has a protrusion 13, which is a shaft part, protruding diagonally from one corner of the outer surface thereof, and an engagement recess 14 is formed on the other side. An engaging recess 15 of the same size is provided adjacent to the engaging recess 14, and both engaging recesses are located on the same circumference around the protrusion 13.

The front lid 2 covers the ventilation opening 31. In the front lid 2, the front plate portion 24 has a square front shape, which is the same as the front shape of the abutment frame 1, and the side cross section is L-shaped. As shown in FIGS. 2 and 4, hinge holes 22, 22 are formed on the bent side of the upper side of the front lid 2, that is, on the upper side of the side plates 21, 21.
The protrusion 13 of the abutment frame 1 is loosely fitted into each hinge hole, and the front cover 2 can swing back and forth with respect to the abutment frame 1 using this fitted portion as a hinge. Further, the inner surfaces of the side plate parts 21, 21 of the front lid 2 are provided with locking protrusions 23, 23 projecting as shown in FIGS. It is engaged with the mating recess 14 and positions the front lid 2 to close. When the locking protrusion 23 engages with the other engagement recess 15, the opening position of the front cover 2 is determined. When the front cover 2 is in this open position, the front plate part 24 is in a substantially hanging state, that is, in a state perpendicular to the ventilation direction of the ventilation opening 31, and there is a predetermined gap 4 between the lower part of the front surface of the support frame 1 and both sides. It opens up and allows air to circulate.

A recess 5 for gripping is provided at the joint between the front plate part 24 of the front cover 2 and the lower end of the support frame 1 to facilitate opening and closing of the front cover.

As shown in FIGS. 2 and 3, the mounting tube 3 has a front opening as a ventilation opening 31, and a collar 32 is provided on the outer periphery of the front.
It comes into contact with the holding part 16 on the back side, and the claw 17 is inserted from the back side.
It is stopped at A long hole 33 is formed on the outer periphery of the mounting tube 3, and a mounting piece 34 is provided inside the hole from the rear end of the long hole. This mounting tube is inserted into the indoor end of the support pipe P inserted into a ventilation hole formed in the wall W, and is fixed by raising the mounting piece.

A protrusion 18 (FIG. 2) is provided around the entire outer periphery of the ventilation hole 11 on the front surface of the support frame 1.

Next, how to use it will be explained.

In the state shown in the first figure, the front cover 2 closes the ventilation opening 31, so air cannot circulate and ventilation is interrupted.

From this state, the front cover 2 is swung clockwise (in the direction of the arrow in FIG. 1) about the protrusion 13 using the handle recess 5, and when it reaches the position indicated by the chain line, it comes out of the engagement recess 14. The locking protrusion 13 engages with the engagement recess 15, and its front cover is fixed, and the front plate portion 24 is brought into a substantially hanging state as shown by the chain line in FIG.

As a result, the left, right, and lower sides of the back surface of the front lid 2 are opened, and air from inside and outside the room circulates through the gaps 4 on three sides, thereby performing ventilation. At this time, due to the presence of the protrusion 18 provided on the front surface of the support frame 1, the outside air is blown out over the protrusion and is not blown out directly along the front surface of the support frame, so there is an advantage that the wall W is not contaminated. Further, when this is opened, a part of the air from the ventilation opening 31 hits the inner surface of the front plate part 24 and flows out downward.

A second embodiment will be described with reference to FIG.

In addition, for the purpose of explaining this example, the same reference numerals are given to the constituent members corresponding to those of the above example.

This example is characterized by the support means for attaching the front cover 2 to the support frame 1 and the front cover regulating means. That is, to explain the supporting means, bearing plates 12, 12 are provided projecting from the upper front surface of the support frame 1, and a shaft 6 is installed between both bearing plates. A bracket 25 hanging from the upper inner side of the front lid 2 is rotatably attached to the shaft 6.

Further, to explain the regulating means, the vertical part of the L-shaped spring plate 7 is fixed to the back surface of the front lid 2, and the engaging recess 71 is provided in the horizontal part. Ventilation opening 31 in mounting tube 3
A locking protrusion 35 is provided at the lower part of the inner periphery, and the engagement recess 71 can be engaged therewith. When the front lid 2 is opened, the locking protrusion 35 is engaged in the engagement recess 71,
The open position of the front lid 2 is fixed.

In this example, the support frame 1 and the mounting tube 3 are integrally formed. Projections 19 all around the front of the frame
is provided. This protrusion is for detouring outside air so that it does not directly hit the wall W.

The front lid 2 swings around an axis 6 and opens a ventilation opening 3.
1 is opened and closed, and air flows through the gap 4 at the left and right sides and bottom of the front lid.

In each of the above examples, if the same pattern as the wallpaper on the wall W is displayed on the front of the front plate part 24 of the front cover 2 as necessary, its presence will be difficult to recognize, which is more preferable from the viewpoint of the aesthetics of the room. .

(Effects of the invention) As explained above, according to the invention, the front cover covers the front of the ventilation opening, so even if a curtain is placed in front of it, the ventilation function is not impaired, and the outside air can flow through the ventilation opening. Since the air does not flow straight into the room, the curtains are less likely to get dirty, and since the air vents cannot be seen directly, the aesthetics of the room are not compromised. Further, the front surface of the front plate portion of the front cover can be effectively used as a decorative surface. In addition, when the front cover is in the open position, the front panel is in a substantially hanging state, so that some of the air from the ventilation openings flows downward and does not directly hit objects located in front of the front cover, such as curtains. The front cover can be opened and closed smoothly because the curtain is not easily soiled and there is no risk of hitting objects that are close to the front cover when the curtain is opened. Since the side cross-sectional shape of the front cover is formed into a substantially L-shape, the front cover can easily be placed in a hanging state in the open position. In addition, since a mounting tube is provided at the rear of the mounting frame to be inserted into a ventilation hole formed in the wall, installation into the ventilation hole is facilitated.
