BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator for a fitting having an indoor side inner plate having a large number of ventilation holes and a movable plate for opening and closing the ventilation holes, and more particularly to the structure of an opening / closing operation member thereof.

[0002]

2. Description of the Related Art Various windows and doors are provided with a ventilator as a part of a crosspiece or separately from the crosspiece, and the ventilator is provided with a large number of ventilation holes in an inner plate facing the indoor side. , A movable plate that opens and closes the ventilation hole. There are two types of movable plates, one with a ventilation hole that slides in the longitudinal direction, that is, the arrangement direction of the ventilation holes, and one that does not have a ventilation hole that slides in and out of the inner plate at the same time as it slides. For slide type ventilation holes, ventilation holes of the same number, shape and arrangement as the ventilation holes of the inner plate are opened in the movable plate, and if the ventilation holes of the inner plate and the movable plate are matched, it becomes a ventilation state. The position of the ventilation hole is changed to the closed state. Further, in the proximity / separation type without ventilation holes, a flat plate is used as a movable plate, and the movable plate is rotatably supported so as to be adjacent to or separated from the inner plate. . In either type, an operating member such as a knob for moving the movable plate is attached. In order to fix the movable plate in the open position and the closed position, the operating member forms a leaf spring in a dogleg shape as described in, for example, Japanese Utility Model Laid-Open No. 62-171736. Fix the top part of the leaf spring to the indoor side and the outdoor side plate material, press the top part of the leaf spring against the slide type movable plate, and into the stop holes provided corresponding to the open and closed positions of the movable plate. A structure in which the top of the leaf spring is fitted and fixed, and
No. 191687, the movable plate is pressed against the inner plate by the force of a leaf spring to prevent the movable plate from moving easily, and the one described in Japanese Utility Model Laid-Open No. 63-86289. As described above, there is a structure in which the movable plate is held in the open and closed positions by friction between the movable plate and the guide member engaging with the movable plate.

[0003]

However, as described above, in the structure in which the movable plate is held in the open and closed positions depending on the spring force or the frictional force, the spring force or the frictional force, that is, the movable plate is used. If the fixing force is small, the movable plate may move due to vibration or shock caused by opening and closing, and the movable plate may move from the closed position to the open position or from the open position to the closed position. On the contrary, if the spring force or the frictional force for fixing the movable plate is increased in order to eliminate such a problem, a large force is required for the opening / closing operation, and the operability is deteriorated.

In view of the above problems, the present invention reliably holds the movable plate without moving the movable plate from the open and closed positions even when a shock is applied to the ventilator. An object is to provide a ventilator for a fitting that has a structure that can reduce the opening / closing operation force.

[0005]

In order to achieve the above-mentioned object, the present invention provides an inner plate facing a room and having a ventilation hole, and a movable plate with a ventilation hole that slides along the inner plate. Or, in a ventilator of a fitting provided with a movable plate without a ventilation hole that opens and closes the ventilation hole by moving toward and away from the inner plate upon sliding, an operating member that moves together with the movable plate in combination with the movable plate. And a spring for urging the operating member toward the indoor side, the inner plate is provided with an opening for exposing a part of the operating member, and both ends in the sliding direction of the indoor side surface of the operating member. And a center portion provided with protrusions protruding toward the inside of the chamber, and the width of the opening provided in the inner plate in the operating member slide direction is determined by the central protrusion of the operating member and one of the protrusions at both ends. Both are set to a width that can be exposed from the opening Open the movable plate, in the closed position,
In each case, the projection on one end of the indoor surface of the operating member is locked to the edge on one end side of the opening of the inner plate, and the one end of the central projection is on the edge on the other end side of the opening. It is characterized by having a structure that is locked to.

[0006]

As described above, according to the present invention, in the open and closed positions, the force of the spring exposes the one end side projection on the indoor side of the operation member and the central projection to the opening of the inner plate, and these projections are exposed. Since the structure is locked to the edge of the opening, even if a shock is applied to the movable plate, the locking structure prevents the movable plate from moving in the sliding direction. The spring force that exposes the projection of the operating member in the opening is only enough to bias the projection and the edge of the opening so that the spring force is weak and the spring force is weak. In addition, the operation force for releasing the locking at the time of opening / closing operation becomes small.

An opening / closing guide 15 is used to open and close the plate 11 by rotating the plate 11 about its shaft portion 11a.

The inner plate 7, the outer plate 9 and the movable plate 11 are made of extruded aluminum alloy or resin, and the operating member 12, the housing 13 and the guide 15 are made of resin.

FIG. 1 is a view seen from the indoor side of FIG.
As shown in the cross-sectional views of (B) and (C), the housing 1
Reference numeral 3 denotes a box shape having an opening on one side, and the operation member 12 is slidably fitted in the housing 13 and assembled. The operation member 12 has two recesses 16 on the back surface thereof.
A coil spring 14 is housed between the housing 6 and the bottom surface of the housing 13. The housing 13 is fitted into an opening 17 provided in the movable plate 11, but the vertical width of the opening 17 does not hinder the rotation of the movable plate 11 when the movable plate 11 is opened and closed.
The lower surface side of the housing 13 is formed as an inclined surface, and a slight gap is provided between the lower surface and the lower edge of the opening 17. As shown in FIG. 1B, the width x of the housing 13 in the indoor / outdoor direction is set to be slightly smaller than the distance between the inner plate 7 and the outer plate 9, and the housing 13 together with the operating member 12 forms these plates 7. , 9 together with the movable plate 11 can be slid to the left and right.

The operation member 12 has a protrusion 18 formed in the center of the surface on the indoor side, and the inside of the protrusion 18 has a recess 19 for receiving a finger during operation. Further, the operation member 12
The projections 20 and 21 are formed at both ends on the indoor side. FIG.
As shown in (B), the dimension from one end of the central protrusion 18 of the operation member 12 to the outer end up to the protrusion 20 or 21 on the opposite side of the one end is equal as indicated by a, and this dimension a is the inner plate. It is slightly shorter than the lateral width b of the rectangular opening 22 provided in No. 7 (a <b). The vertical width c of these protrusions 18, 20, 21 is slightly smaller than the vertical width e of the opening 22 of the inner plate 7 as shown in FIG. Smaller than the vertical width d of the indoor side end of (c <
By setting e <d), the projection 18 can project from the opening 22 so that the operating member 12 does not slip out of the opening 22 toward the indoor side. And the central protrusion 18
Is slidably fitted in the opening 22 of the inner plate 7 to the left and right. In addition, as shown in FIG.
The protrusion width f of the operation member 12 is set to be larger than the protrusion width g of the protrusions 20 and 21 at both ends.
Is slightly larger than the dimension h from the bottom surface of the housing 13 to the tip on the opening side (i + f>
h), the thickness i of the operating member 12 and the projections 20 at both ends,
21 is smaller than the dimension h from the bottom surface of the housing 13 to the tip on the opening side (i + g <h)
The protrusions 20 and 21 at both ends can be submerged in the housing 13, that is, the inner plate 7, and the central protrusion 18 is not formed in the inner plate 7.

As shown in FIG. 6, a guide mounting groove 23 is formed on the surface of the inner plate 7 on the outdoor side, and one end side of the opening / closing guide 15 is fitted into the groove 23 to caulk the formation portion of the groove 23. It is fixed by. The opening / closing guides 15 are provided at two places on the left and right in order to bring the movable plate 11 into close contact with the inner slope 7, as shown in FIG. On the upper surface of the opening / closing guide 15, there is a guide groove 15a in which an intermediate portion j is inclined in the indoor / outdoor direction and both ends k and m are parallel to the inner plate 7. Piece 2
5 is slidably fitted in the guide groove 15a.

In this structure, as shown in FIG. 6, the engaging piece 25 of the movable plate 11 is connected to the guide groove 15 of the opening / closing guide 15.
In the state where it is fitted into one end k of a, the movable plate 11
Takes a vertical posture, and the ventilation hole 6 is closed by the movable plate 11. At this time, as shown in FIG. 3, the character "closed" appears on the indoor surface of the operation member 12. Further, in the operation member 12, as shown in FIG. 1B, the central projection 18 and the projection 20 at one end are exposed in the opening 22 by the force of the coil spring 14, and the end surfaces of these projections 18 and 20 are Opening 22
Is locked to the edge of. Since the projections 18 and 20 are locked to the edges of the opening 22 in this manner, the operating member 12 is disengaged from the opening 22 even when the inner plate 7 is moved in the left-right direction due to vibration or shock caused by opening and closing. Therefore, the movable plate 11 in which the operating member 12 is fitted into the opening 17 through the housing 13 does not shift in the left-right direction with respect to the inner plate 7.

When the movable plate 11 is separated from the inner plate 7 to release the blockage of the ventilation hole 6, a finger is put in the recess 19 of the operating member 12 and the operating member 12 is pushed against the force of the coil spring 14.
The projection 20 is retracted through the opening 22, and the operation member 12 is moved rightward as indicated by an arrow R in FIG.
As a result, the movable plate 11 is also moved to the right. As a result, the engagement piece 25 on the lower side of the movable plate 11 shown in FIG. 6 slides through the guide groove 15a from the end portion k to the inclined portion j and reaches the end portion m. This allows the movable plate 11 to move from the closed state indicated by the solid line to 2
It will be in the open state indicated by the dotted line. Further, when the end of the projection 18 of the operating member 12 reaches the edge of the opening 22 of the inner plate 7 and abuts against it, further movement is blocked, and the projection 21 at the other end of the coil spring 14 in the opening 22. Protrusion 2 by force
One end is locked to the edge of the opening 22. At this time, the character "open" appears on the indoor side surface of the operation member 12, and the protrusions 18 and 21 are locked to the edge of the opening 22 to prevent the operation member 12 from moving. Movable plate 11
Is prevented from being moved in the closing direction by an impact.

The force of the coil spring 14 is the opening 22.
Since the projections 18 and 20 or 21 need only be strong enough to be projected, the operation member 12 can be easily pushed in with a finger, and the opening / closing operation can be facilitated. The coil spring 14
The number of the coil springs may be one, but by disposing two coil springs 14 at the left and right positions of the concave portion 19 serving as the operating portion as in the present embodiment, a spring having a weaker spring force than that of the case of using one coil spring is used. And the touch becomes softer.

Further, as in this embodiment, the height of the protrusion 18 at the center of the operating member 12 is set to a height at which the protrusion 18 does not sink into the inner plate 7, so that the operating member 12 is temporarily not operated. Even if it is pushed and moved as necessary, there is no possibility that the protrusion 18 will go under the inner plate 7, and it is not necessary to pay close attention to the operation of the operation member 12.

FIG. 7A shows an operating member 12A according to the present invention.
FIG. 11 is a view showing another example of the operating member 12A in which the spring 30 is integrally formed, and as shown in the cross-sectional view of FIG. 7B, the operating member is provided in the opening 17 of the movable plate 11. 12A is fitted so that the central projection 18 on the indoor surface of the operating member 12A and one of the projections 20 and 21 on both ends are exposed from the opening 22 of the inner plate 7, and the spring 30 formed on the operating member 12A. Is pressed against the outer plate 9. According to this embodiment, there is an advantage that the housing 13 and the coil spring 14 are unnecessary and the number of parts can be reduced. As shown in FIG. 7C, a leaf spring 31 may be used as a spring, the leaf spring 31 may be attached to the back surface of the operation member 12B and the leaf spring 31 may be pressed against the outer plate 9. The leaf spring 31 can also be used between the housing 12 and the operating member 12 in the above embodiment.

If the movable plate 11 is not provided with a ventilation hole as in the present embodiment, and the movable plate 11 is moved closer to or away from the inner plate 7, the movable plate 7 is provided with a ventilation hole. Since those that do not use are used, the rain swirl is good, and since the ventilation hole can be configured in the shape of a small slit, there is an advantage that it is excellent in design, but the present invention is not limited to this. As shown in the perspective view of FIG. 8 (A), the exploded perspective view of FIG. 8 (B), and the transverse sectional view of FIG. 9, ventilation holes 6A (32 is an insect net provided in the ventilation holes 6 of the inner plate 7) Ventilation hole 6 of inner plate 7 by sliding movable plate 11A having
It can also be applied to the one that opens and closes. In FIGS. 8 and 9, the same reference numerals as those in FIGS. 1 to 6 indicate parts or portions having the same function. The ventilation hole 6 of the inner plate 7 and the movable plate 1 are the same.
The state in which the ventilation holes 6A of 1A are in agreement is the state in which the ventilation holes 6 are open, and the state in which the positions of these ventilation holes 6 and 6A are different is the state in which the ventilation holes 6 are closed. Also in this embodiment, as in the case of the above-mentioned embodiment, the operation force is reduced and the movable plate 1 by the impact
A movement prevention effect of 1 A is obtained. It goes without saying that the spring structure shown in FIG. 7 can also be adopted in the embodiments of FIGS. 8 and 9.

Although the present invention has been described with reference to the embodiments, various changes and additions are made to the structure and combination of the inner plate 7, the movable plate 11, the outer plate 9 and the operating member 12 without departing from the scope of the present invention. Is possible.

[0019]

According to the present invention, when the movable plate is in the open or closed position, the central and one end projections provided on the operation member biased toward the room by the spring are the openings of the inner plate. Since the movable plate is configured to be locked to the edge of the part, the movable plate does not move from the open position and the closed position even when an impact is applied to the ventilation body, and the movable plate is reliably held. Further, since the spring force only needs to be strong enough to expose the projection from the opening, the spring force can be weak and the operation member can be pushed in to remove the projection at the end from the edge of the opening. The opening / closing operation force can be reduced, it can be opened and closed easily, and the operability is improved.
