Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cover for a ventilation louver in a house or the like. More specifically, the present invention relates to a cover for a ventilation louver that can improve the interior environment and living environment of a ventilation louver in a house or the like.

[Problems to be Solved by Prior Art and Ideas] As shown in FIG. 9, a conventional ventilation louver in a house is not provided with a cover, and the indoor side thereof is exposed on the wall surface. Furthermore, in a general opening/closing type louver 3, a lever 24 for opening and closing the closing member (damper) N protrudes from the surface of the louver 3 toward the indoor side. Therefore, it does not look good, and there are problems such as outside air blowing into the room.

The purpose of this invention is to improve the appearance of the indoor side of the ventilation louver and to prevent outside air from directly blowing into the room.

[Means for Solving the Problems] The ventilation louver cover of the present invention has (a) a left and right side consisting of a bottom part fixed to the left and right upper corner parts of the ventilation louver, and a rising piece rising at right angles from the bottom part. It consists of a pair of L-shaped members, (b) a cover equipped with left and right ribs rotatably and movably connected to the left and right rising pieces, and (c) the rising pieces are When the cover is closed, the height is set to leave a gap between the cover and the ventilation louver, (d) the lower end of the cover extends below the lower end of the ventilation louver, and (e) the left and right In at least one of the pairs of the L-shaped member and the rib, (e-1) a plurality of annularly arranged engagement recesses are formed on the sliding surface of either the rising piece or the rib. (e-2)
An engagement protrusion that engages with the engagement recess is formed on the other sliding surface, and (e-3) the rising piece and the rib are rotatably connected by a headed pin; 4) An elastic ring is interposed between the head of the pin and a mating member facing the head to press the upright piece and the rib against each other.

[Function] Since the cover is attached to the ventilation louver via a hinge with a detent, it can be held at any angle.

Normally, keep the cover parallel to the wall.
Hide the ventilation louver. This improves the view inside the room. Additionally, wallpaper or paintings can be pasted on the front of the cover, making it look even better.

Further, although the ventilation louver is usually provided at the upper part of the room, the lower end of the cover extends below the lower end of the ventilation louver, so the ventilation louver cannot be seen even when looking up from below.

Also, since the cover is attached with a certain gap left between it and the ventilation louver, outside air is blocked by the cover and flows downward along the wall surface. Therefore, it does not cause discomfort to those inside the room. Furthermore, because of the gap, the operating lever of the opening/closing device (damper) of the ventilation louver does not interfere with the cover.

When operating the opening/closing device, the cover can be tilted significantly upward. In addition, by keeping the cover slightly tilted upward, the direction of the wind can be adjusted to some extent.

Since the L-shaped member can be attached to the ventilation louver, the cover of the present invention can be easily attached to the existing ventilation louver.

[Example] Next, the ventilation louver cover of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view showing an embodiment of the cover of the present invention together with a ventilation louver, Figs. 2-3 are perspective views and sectional views of main parts of the cover shown in Fig. 1, and Figs.
5 is a cross-sectional view of main parts showing other embodiments of the hinge according to the present invention, FIG. 6 is a cross-sectional view showing an example of the state in which the ventilation louver and cover shown in FIG. 1 are attached, and FIG. FIG. 7 is a perspective view showing how the L-shaped member of the hinge shown in FIG. 2 is attached;
FIG. 8 is a perspective view of the L-shaped member of the hinge shown in FIG. 2, viewed from the back side.

As shown in FIG. 1, the ventilation louver cover of the present invention is composed of an L-shaped member 1 attached to the ventilation louver 3, and a cover 14 rotatably attached to the L-shaped member 1.

The ventilation louver 3 is attached to the indoor side of a ventilation hole (communication hole) provided in the outer wall,
It is usually constructed as a frame having slit-like or grid-like parts. In addition, as shown in Figure 6, the grid-like part of the louver 3 has indoor IN and outdoor
Some have an operating lever 24 inserted therethrough for opening and closing the communication hole 23 with the OUT. In order to secure a space for such an operating lever 24 and a flow path for outside air, the cover 14 is kept some distance from the wall surface even when it is closed.

The cover 14 shown in FIG. 1 is constructed such that the L-shaped member 1 is attached to the corner of the upper end of the louver 3, and then the cover 14 is connected to the L-shaped member 1.

The front surface of the cover 14 is formed as a panel surface 14a. Therefore, for example, the same material as the interior material such as wallpaper around the louver 3 can be used on the panel surface 14a.
Since it can be pasted or installed on the cover 14, the louver 3 and operation lever 2
It has the advantage that mechanical parts such as 1 are covered with the same interior material as the surrounding area, making them less noticeable. Note that the ventilation louver 3 is normally provided at the top of the wall, and as will be described later, the cover 14 is separated from the wall, so the lower dimension of the cover 14 is adjusted so that the louver 3 is not visible. It is longer than Garari 3.

The L-shaped member 1 has a bottom part 1a formed with an L-shaped groove 4 (see FIG. 8) that fits into the corner part 18 of the ventilation louver 3, and a rising piece 1b rising from the bottom part 1a at a substantially right angle. It is configured.

As shown in detail in FIG.
b and the rib 2 of the cover 14 have holes 5,
A pin 8 having a head 7 is inserted through the holes 5 and 6. An elastic ring 9 made of sponge or the like is placed between the head 7 of the pin 8 and the rib 2.
is mediated. As the elastic ring, in addition to a sponge, for example, a wave washer 9a shown in FIG. 4 or a disc spring 9b shown in FIG. 5 may be used. A screw hole 11a is formed at the tip of the pin 8, into which a screw 11 for attaching the washer 10 can be screwed, and as shown in FIG.
0 and the head 7 sandwich the rising piece 1b and the rib 2 with some allowance in the axial direction.

The inner surface 2a of the rib 2 and the outer surface 1c of the rising piece 1b are in sliding contact with each other due to the action of the elastic ring 9, and each constitute a sliding contact surface.

The inner surface 2a of the rib 2 is formed with a plurality of annularly arranged engagement grooves 12 as shown in FIG. A plurality of engagement protrusions 13 that can be engaged with the engagement groove 12 are formed so that the engagement protrusions 13 can be engaged with the engagement grooves 12.

The hinge constructed as described above is the cover 14.
When the side is rotated in the direction of arrow A or arrow B in FIG. 2, the engagement projections 13 sequentially engage and disengage from the plurality of engagement grooves 12. When it is finally stopped at the desired angular position, the engagement position is maintained by the engagement between the engagement protrusion 13 and the engagement groove 12, which are pressed against each other by the elastic ring 9. A detent effect is performed.

Since the washer 10 is subjected to repeated tensile forces in the axial direction, it is preferable to apply an adhesive or the like to prevent the screws 11 from loosening. In that case, for example, as shown in FIG. 4, a small diameter portion 8a is provided at the tip of the pin 8, and after passing the pin 8 through the rising piece 1b and the rib 2, the pin 8 is inserted between the tip of the small diameter portion 8a and the small diameter portion 8a. The washer 10 may be heat-sealed. Alternatively, as shown in FIG. 5, use a pin 8 having a locking portion 8c and a cross-shaped slit 8d on the tip side, insert the pin 8 into the rising piece 1b and the rib 2, and then insert the screw 8b.
The tip end side of the pin 8 may be expanded by screwing into the slit 8d.

In the hinge shown in FIGS. 2 and 3, a pin 8 separate from the rib 2 and the like is used, but the pin 8 may be integrally provided to protrude from the rib 2 or the rising piece 1b.

The rib 2 formed on a part of the cover or the rising piece 1b of the L-shaped member 1 is configured to have sufficiently high flexibility and elasticity, and for example, the first
As shown in the figure, the ribs of the cover 14 are arranged on the outside (or inside) of each of the two L-shaped members 1, and the sliding surfaces are elastically brought into contact with each other by the elasticity of the ribs 2 and the rising pieces 1b themselves. In this case, the rib 2 or the rising piece 1b itself can be used as the elastic means.
In that case, such a rib 2 or the like can be used as an auxiliary means for the elastic ring 9, but the elastic ring 9 itself can also be omitted.

If the elastic ring 9 is omitted in this way,
In particular, it is preferable to use a separate pin 8 because it frees the ribs 2 and the like from bending, and the engagement and disengagement between the engagement protrusion 13 and the engagement groove 12 becomes smoother. However, if a pin integrated with the rib 2 or the rising piece 1b is used as described above, the washer 10 and screw 11 shown in FIG. 2 in addition to the elastic ring 9 can be omitted, making the mechanism extremely simple. There are advantages that can be achieved.

The cross-sectional shapes of the engagement groove 12 and the engagement protrusion 13 are not particularly limited, but shapes such as semicircular, trapezoidal, triangular, etc. that allow the engagement and disengagement of the engagement protrusion 13 and the engagement groove 12 to be relatively smooth are preferable. preferable.

Further, the shape of each of the engaging grooves 12 and the engaging protrusions 13 is, for example, an elongated fan shape extending in the radial direction, but is not limited thereto. Further, instead of the engagement groove 12 and the elongated engagement protrusion 13, for example, a hemispherical engagement recess, an engagement protrusion, etc. may be used.

It is preferable to have a large number of engagement recesses such as engagement grooves, since the degree of freedom in locking positions is higher, but the number is usually about 10 to 20. Further, the number of engaging protrusions is preferably three or more and provided at approximately equal intervals in order to smooth the detent action, but is not particularly limited.

In the case of the hinge shown in FIGS. 2 and 3, in order to simplify the molding work, especially the structure of the mold, the engagement protrusion 13 is formed on the L-shaped member 1 side, and the engagement groove 12 is formed on the cover 14. Although they are formed on the sides, they may of course be reversed.

In the ventilation louver cover of the present invention, when the cover 14 is opened or closed, the engagement protrusion and the engagement groove engage in sequence, and the cover, interior surface, louver, etc. are not closed instantly and impactfully. It has the advantage of not being damaged. Furthermore, since the cover can be left partially open, even short children can open and close it.

The hinge with detent related to this invention is
It may be used for both corners of Garari 3, respectively.
It may be used only on one side and connect the other side with a conventional hinge, preferably one with some axial movement. Furthermore, the ribs 2 of the cover 14 shown in FIG.
On the left side, it may be configured to be placed inside.
In this case, the engagement protrusion 13 of the hinge is connected to the engagement groove 1.
2, the entire cover 14 moves somewhat to the right. Therefore, since the elasticity of the ribs 2 etc. cannot be utilized, it is necessary to provide an elastic ring 9 in the same way as shown in FIGS. Since it moves, it has the advantage of smoother operation.

If the louver 3 is configured in advance as a louver with a cover, the rising piece may be directly formed integrally with the frame of the louver 3 without using the L-shaped member 1. However, when attaching the cover 14 to the louver 3 already attached to the building, an independent L-shaped member as described above is used.

Next, preferred attachment means for such a hinge that is attached later will be explained.

The L-shaped member 1 shown in FIGS. 7 and 8 is provided with a mounting protrusion 15 that is fitted into the gap S of the louver 3. Note that when forming the L-shaped groove 4, such a protrusion 15 can be left in place. A slit 16 parallel to the gap S is formed in the projection 15, and a tapered hole 17 is formed at the base of the slit 16.

After fitting this thing into the corner part 18 of the louver 3 as shown in FIGS. The small diameter side of the tapered hole 17 is expanded. Therefore, the portion 20 divided by the slit 16 bends somewhat in the direction of the arrow P, and the protrusion 15 expands within the gap S.
The width of the L-shaped groove 4 becomes narrower. Therefore, Garari 3
The L-shaped member 1 can be fixed very easily and reliably.

In order to further ensure the fixing effect, a protrusion or pawl 22 that can engage with the lattice member 21 of the louver 3 may be provided near the lower end of the protrusion 15.

The cover 14 of the ventilation louver is normally placed so that it does not get in the way when operating the operating lever (24 in Figure 6) for opening and closing the aforementioned communication hole.
It is configured to open up to about 180°.

The cover of the ventilation louver of the present invention can be made of any material, but it is usually made of any material in order to facilitate the formation of the engagement protrusion and the engagement recess, and to improve the slipperiness between them. Those molded from synthetic resins such as polyamide and polyacetal are preferred.

[Effects of the invention] By providing the cover of the invention, the appearance of the ventilation louver is improved and it is possible to prevent outside air from blowing directly into the room. Furthermore, since the cover of the present invention is equipped with a unique detent mechanism, it can be locked at almost any angular position. Furthermore, since the mechanism is extremely simple, it can be manufactured at low cost and has the advantage of being less likely to break down.
