Description

  The present invention relates to a ventilation port cover attached to the indoor side of a ventilation port that leads from the outside to the room, and more specifically, the ventilation port can be opened and closed stepwise, and the ventilation port is fully opened or fully closed by a single operation. In addition, the present invention relates to a ventilation port cover that prevents the ventilation port from being fully opened although it is not intended and that allows the direction of the air taken into the room to be easily and finely adjusted.

  Since housing in recent years has become highly airtight, if sufficient ventilation is not provided, there is a possibility that sick house syndrome will occur due to volatile organic compounds (VOC) used in wall materials and the like. For this reason, the revision of the Building Standards Act of the year 2003 required the installation of equipment that can be constantly ventilated as a countermeasure against sick house syndrome, and accordingly, a vent cover was also installed on the indoor side of the building.

  Here, a description will be given of a conventionally used vent cover. Generally, a vent cover is a cylindrical main body inserted into an air supply through hole formed in a wall of a building, and the air supply. And an air volume adjusting plate as a lid for closing the through hole for opening and closing, and the air volume adjusting plate is supported by the main body and can adjust the opening / closing ratio of the air supply through hole.

  That is, a bar-shaped slider is provided on the back surface of the air volume adjusting plate so as to project toward the main body, while the main body is provided with a slider receiver into which the slider protruding from the air volume adjusting plate is inserted. In addition, by adjusting the insertion ratio of the slider with respect to the slider receiver, the opening / closing ratio of the air supply through hole by the air volume adjusting plate can be adjusted.

  At this time, in the conventional ventilation port cover, the opening / closing ratio of the air supply through-hole by the air volume adjusting plate can be adjusted in stages by making the slider extendable in stages with respect to the slider receiver. There was one that adopted a stepped expansion and contraction mechanism.

  That is, in this method of expanding and contracting stepwise, the slider is urged in an extending direction by an elastic means such as a spring, and a plurality of locking recesses are formed in the slider along the longitudinal direction to Is provided with a locking claw portion that is locked to a locking recess formed in the slider, and by changing the position of the locking recess of the slider that the locking claw locks, the slider is moved against the slider receiver. It can be expanded and contracted in stages.

JP 2006-180976 A JP 2006-180977 A JP-A-9-158917 Japanese Patent Laid-Open No. 9-242723 JP 11-315812 A

  By the way, in the conventional stepwise expansion / contraction mechanism, there are cases where it expands stepwise and contraction stepwise, but in a mechanism that expands stepwise, it cannot be fully opened at once and cannot be contracted stepwise. This problem has been pointed out (see JP-A-11-315812).

  Further, with the mechanism that contracts in stages, it has been pointed out that although it is possible to contract in one operation by pushing the slider at a time, it cannot be expanded in stages (Japanese Patent Laid-Open No. 9-158917). JP, 9-242723, A).

  Furthermore, in the mechanism that contracts in stages, the latching claw and the latching recess are unlocked by pushing the slider further in a state where the slider is completely shrunk and the air volume adjusting plate is fully closed. Because the slider extends to the longest and the air flow adjustment plate is fully open, when the slider is pushed all at once to fully close the air flow adjustment plate, the slider is moved beyond the position where the air flow adjustment plate is fully closed. In this case, the slider may return to the longest position and the air volume adjusting plate may be fully opened, contrary to the intention of fully closing the air volume adjusting plate. This was particularly likely to occur when the air volume adjusting plate was to be fully closed all at once in order to prevent the wind from entering the room when a wind such as a typhoon was strong.

  Furthermore, some of the conventional vent cover has a wind direction controller to adjust the wind direction, but with the conventional controller, it is not possible to make fine adjustments simply by adjusting the wind direction. The wind direction adjustment work was also troublesome.

  Therefore, the present invention includes a cylindrical main body portion that is inserted into an air supply through hole formed in the wall of the building, and an air volume adjusting plate as a lid that closes the air supply through hole so as to be freely opened and closed. In the vent cover, it is possible to open and close the air supply through-hole with the air flow adjustment plate in stages and to open and close the air supply through-hole with the air flow adjustment plate in one operation. In addition, even when the air flow adjustment plate is pushed in with the air supply through hole fully closed, the air supply through hole will not open, and the direction of the air taken into the room can be easily and finely adjusted. The problem is to provide a vent cover.

The vent cover of the present invention is

  In the vent cover according to the present invention, the indoor side opening of the main body inserted into the air supply through-hole formed in the wall of the building is opened and closed by the air flow adjusting plate so that the air flow adjusting plate can be opened and closed. By inserting the slider projecting into the slider receiving part supported by the main body part so that it can be inserted and removed freely, the air volume adjusting plate can be moved forward and backward with respect to the main body part, and the slider insertion ratio with respect to the slider receiving part is adjusted. The opening / closing ratio of the indoor side opening of the main body can be adjusted by the air volume adjusting air volume adjusting plate. The slider has a plurality of locking recesses and is urged in a direction to be removed from the slider receiving portion, while a slider having a locking claw portion that locks in the locking recess protrudes from the slider. Prevents movement in the direction.

  Accordingly, by releasing the locking between the locking claw and the locking recess, it is possible to adjust the insertion ratio of the slider with respect to the slider receiving portion. By locking the pawl portion, the slider can be expanded and contracted in stages, and the locking pawl portion and the locking recess portion until the locking pawl is locked to the locking recess at the forefront or the end. The slider can be expanded and contracted at once by releasing the lock.

  In addition, the stopper prevents the slider from moving in the direction of removal from the slider receiver, and unless the stopper is operated, the slider does not move in the direction of removal from the slider receiver and the air volume adjustment plate does not move. Even if the air volume adjusting plate is pushed in when the adjusting plate is in the fully closed state, the slider does not move to the air volume adjusting plate, and the air volume adjusting plate is not fully opened although it is not intended.

  Further, in the ventilation port cover of the present invention, the airflow direction adjusting tool is provided with the airflow direction adjusting tool on the main body part side, and the airflow direction adjusting tool is provided on the outer periphery of the support part protruding from the airflow adjusting plate on the main body part side.

FIG. 1 and FIG. 2 are cross-sectional views for explaining the structure of the vent cover of the present embodiment. It is a ventilation port cover of an Example. In the figure, W is the wall of the building, and W1 is the surface of the indoor wall.

  The vent cover 1 of the present embodiment can freely open and close the main body 2 inserted into the air supply through hole W2 formed in the wall W of the building and the indoor opening 201 of the main body 2. The air flow adjusting plate 9 is closed, and the air flow adjusting plate 9 is moved in the front-rear direction with respect to the main body 2 to open and close the indoor opening 201 of the main body 2. That is, the state where the air volume adjusting plate 9 closes the indoor side opening 201 of the main body 2 is the state of FIG. 1, and the state where the air flow adjusting plate 9 is moved to release the indoor side opening 201 of the main body 2 is shown in FIG. It is a state.

  Here, the main body 2 will be described with reference to the drawings. FIG. 3 is a perspective view of the main body 2, FIG. 4 is a front view of the main body 2, and the main body 2 in this embodiment is a building wall. The insertion body 3 is inserted into an air supply through-hole W2 formed in W. This insertion body 3 is a cylinder in this embodiment according to the shape of the air supply through-hole W2. The opening on the front end side is the indoor opening 201.

  And the decorative edge part 4 is continuously provided in the outer periphery of the front-end | tip part of this insertion body 3 toward the outer peripheral side, and this decorative edge part 4 is in order to cover the hole edge of the said through-hole W2 for air supply It is used. The insert 3 does not necessarily have a cylindrical shape. If the shape of the air supply through hole W2 is a square hole, the insert 3 has a rectangular tube shape.

  In the figure, reference numeral 5 denotes a slider receiving portion. That is, in the ventilation port cover 1 of the present embodiment, a slider receiving portion 5 is supported in the insert 3, and the slider receiving portion 5 has a hollow rectangular bar shape, and the insert is supported by the support plate 8. 3 is supported by the central portion.

  That is, four corner portions of the slider receiving portion 5 are continuously provided with plate-like support plates 8 facing in the radial direction, and the distal end portion of the support plate 8 is the inner wall of the insert 3. It is connected to. As a result, the slider receiving portion 5 is supported by a central portion inside the insert 3. However, the support plate 8 does not necessarily have a plate shape, and may be any form as long as the slider receiving portion 5 can be supported inside the insert 3.

  Next, 9 in FIGS. 1 and 2 is an air volume adjusting plate. In other words, the vent cover 1 of the present embodiment has an air volume adjusting plate for closing the opening 201 on the indoor side of the main body 2 so as to be openable and closable. In this embodiment, the air volume adjusting plate 9 is the insert body. 3 is a square plate having an area capable of sufficiently covering the three openings, and is arranged on the inner peripheral side of the decorative edge 4.

  A slider projects from the surface of the air flow adjusting plate 9 facing the main body 2, that is, the back surface of the air flow adjusting plate 9 toward the main body 2. 1 and 2, reference numeral 10 denotes a slider. In this embodiment, the slider 10 is shaped like a square bar, and a locking recess 11 is formed at intervals along the longitudinal direction. It is inserted freely.

  Further, a spring 12 as an elastic body is provided in the slider receiving portion 5, and this spring 12 allows the slider 10 to be removed from the slider receiving portion 5 through the slider 10 inserted in the slider receiving portion 5. Energizing in the direction. That is, the slider receiving portion 5 is open on the indoor side, that is, on the air volume adjusting plate 9 side, and closed on the outdoor side, and the spring 12 is disposed between the closed portion on the outdoor side and the slider 10 inside. Thus, the slider 10 is always urged in a direction to be removed from the slider receiving portion 5. In this embodiment, a small hole is formed in the front end portion of the slider 10 in the longitudinal direction, and the front end of the spring 12 is inserted into the small hole, thereby fixing the position of the spring 12. Yes.

  The slider 10 is prevented from coming out of the slider receiving portion 5 by a stopper. That is, in the figure, 13 is a stopper, and this stopper 13 is movable in a direction perpendicular to the insertion / extraction direction of the slider 10. The stopper 13 is formed with a locking claw 15, which can be locked to a locking recess 11 formed on the slider 10. In a state where the claw portion 15 is locked, the slider 10 cannot move in the direction in which the slider 10 comes out of the slider receiving portion 5, while it can move in the direction in which the slider 10 is inserted into the slider receiving portion 5.

  This relationship will be described in detail. FIG. 5 shows a state in which the slider 10 is inserted into the slider receiving portion 5 and the locking claw portion 15 of the stopper 13 is locked to the locking recess 11 of the slider 10. FIG. 6 is an exploded view of the slider receiving portion 5, the slider 10, and the stopper 13.

  In the drawing, the stopper 13 has a frame-shaped stopper body 14 that is provided around the lower end of the slider receiving portion 5, and the stopper body 14 is in a direction perpendicular to the longitudinal direction of the slider receiving portion 5. A locking claw portion 15 that is locked to a locking recess 11 formed in the slider 10 is formed at the inner circumferential tip.

  On the other hand, the slider receiving part 5 has a guide in which the stopper 13 is slidably fitted, and the stopper 13 is perpendicular to the longitudinal direction of the slider receiving part 5 by fitting in the guide. It is possible to move only in the direction to do. That is, a long guide member 701 is connected to the lower end portion of the slider receiving portion 5 in the direction perpendicular to the longitudinal direction of the slider receiving portion 5 in two upper and lower stages on the outer peripheral side of the opposing side wall. Thus, a guide groove 702 is formed between the guide members 701, and the guide 7 is constituted by the guide member 701 and the guide groove 702.

  Further, in the lower end portion of the slider receiving portion 5, a notch portion 6 is formed in one portion of the side wall other than the side wall where the guide 7 is formed. The stopper 13 is configured to be fitted in the guide groove 702, and the engaging claw portion 15 is disposed to face the notch portion 6, and the slider receiving portion 5 is formed along the guide groove 702. The slider receiving portion 5 is provided around the lower end portion so as to be movable in a direction orthogonal to the longitudinal direction. Further, the stopper 13 is always on the base end side, that is, on the anti-slider receiving side, by a spring 16 interposed between the side wall facing the notch 6 in the slider receiving portion 5 and the base end side of the inner periphery of the stopper main body 14. It is biased to the club side. As a result, the locking claw portion 15 always passes through the notch portion 6 and enters the slider receiving portion 5.

  On the other hand, a lever 17 is connected to the base end side of the stopper main body 14, and in this embodiment, a pressing portion 18 is connected to the distal end portion of the lever 17. And the latching claw part 15 can be taken out from the slider receptacle part 5 by pressing the press part 18 to the stopper main body 14 side and moving the stopper main body 14 to the front end side. In this embodiment, the lever 17 passes through the pressing portion through hole 401 formed in the decorative edge portion 4, and the pressing portion 18 protrudes below the decorative edge portion 4.

  Next, the locking recess 11 formed in the slider 10 has a horizontal surface 1101 formed in a direction perpendicular to the longitudinal direction of the slider 10 from the side surface of the slider 10, and obliquely downward from the innermost portion of the horizontal surface 1101. The tapered surface 1102 is formed. In this embodiment, four locking recesses 11 are formed at intervals along the longitudinal direction of the slider 10, and the locking recesses 11 are formed at the lower end of the slider receiving portion 5. The slider 10 is inserted into the slider receiving portion 5 so as to face the notch portion 6, whereby the locking claw portion 15 is locked in the locking recess 11.

  Here, the locking claw portion 15 has a horizontal surface that contacts the horizontal surface 1101 of the locking recess 11 and a tapered surface that contacts the tapered surface 1102 of the locking recess 11. Therefore, when pressure is applied to the slider 10 in the direction in which it is inserted into the slider receiving portion 5, upward pressure is applied to the tapered surface 1502 of the locking claw by the tapered surface 1102 of the locking recess 11. Since the stopper main body 14 can be moved only in the direction orthogonal to the longitudinal direction of the slider receiving portion 5 by the guide 7, the tip of the stopper main body 14 is provided on the tapered surface 1502 of the locking claw portion 15 by the so-called wedge principle. Pressure is applied toward the side. As a result, the stopper main body 14 moves to the distal end side, the locking claw portion 15 comes out of the slider receiving portion 5 and the locking recess 11 and the locking claw portion 15 are unlocked.

  On the other hand, when a pressure is applied to the slider 10 so as to be removed from the slider receiving portion 5, a downward pressure is applied to the horizontal surface 1501 of the locking claw by the horizontal surface 1101 of the locking recess 11. Similarly to the above, the stopper main body 14 can be moved only in the direction orthogonal to the longitudinal direction of the slider receiving portion 5 by the guide 7, and the pressure on the horizontal surface 1501 of the locking claw portion by the horizontal surface 1101 of the locking recess 11. Therefore, the principle of the wedge does not work, so that the locking of the locking recess 11 and the locking claw 15 is maintained without being released.

  Therefore, the stopper 13 in this embodiment prevents the slider 10 from moving in the direction in which the slider 10 comes out of the slider receiving portion 5 in a state where the locking claw 15 is locked to the locking recess 11. Is allowed to move in the direction of insertion into the slider receiving portion 5.

  The guide 7 is not necessarily configured as described above, and may be any configuration as long as the stopper 13 is movable only in the direction perpendicular to the longitudinal direction of the slider receiving portion 5. Further, as a method for allowing the locking claw portion 15 to enter the slider receiving portion 5, it is not always necessary to use the notch portion 6. In addition, a through hole is formed in the slider receiving portion 5, and the through hole is inserted through the through hole. Thus, the locking claw portion 15 may enter the slider receiving portion 5.

  Further, the stopper 13 is not necessarily provided around the lower end portion of the slider receiving portion 5, and may be provided around any portion along the longitudinal direction of the slider receiving portion 5. In this case, the guide 7 is formed at a location where the stopper 13 is provided around the slider receiving portion 5, and the locking claw portion 15 is provided at a location facing the locking claw portion 15 when the stopper 13 is provided around. Is formed with an insertion hole for insertion into the slider receiving portion 5.

  Moreover, the shape of the slider 10 and the slider receiving part 5 is not specifically limited, It does not necessarily need to be a square bar shape, and may be a round bar shape.

  Next, in FIGS. 1 and 2, 19 is a filter. That is, in the vent cover 1 of the present embodiment, the filter 19 is provided in the insert 3 so that foreign matters such as dust flowing into the main body together with the outside air are captured by the filter 19. This prevents foreign matter such as dust from entering the room. In the present embodiment, the filter 19 has a filter body supported on the inner peripheral side of a filter frame having an outer diameter substantially equal to the inner wall of the insert 3, and the filter body is made of air such as a nonwoven fabric or a mesh. It is a material that does not allow foreign materials such as dust to pass through.

  Next, in FIGS. 1 and 2, reference numeral 31 denotes a wind direction adjusting tool. That is, in the ventilation port cover 1 of the present embodiment, a wind direction adjusting tool 31 is provided on the surface (hereinafter referred to as “back surface”) of the air volume adjusting plate 9 on the main body portion 2 side. The direction of the wind entering the room through the inside of the insertion portion 3 can be adjusted.

  Here, the wind direction adjusting tool 31 will be described. FIG. 7 is a schematic perspective view showing the outline of the back surface of the air volume adjusting plate 9, and the portion indicated by 31 in the figure is the wind direction adjusting tool.

An insertion hole 35 into which the claw portion 3302 is inserted when the column portion 3301 is inserted therein is formed. As a result, while the locking claw 33 is inserted into the support portion 34, the claw portion 3302 is locked to the insertion hole 35 of the support portion 34, so that the support portion 34 protrudes from the back surface of the air volume adjusting plate 9. Has been established.

  Next, the engaging portion will be described. In FIGS. 7, 8 and 9, 39 is an engaging portion, and in this embodiment, the engaging portion 39 is slidable on the outer peripheral side of the support portion 34. It is formed in a ring shape and a part in the circumferential direction is cut away.

  Further, in this embodiment, the engaging protrusions 40 are formed at two opposing positions on the inner peripheral side of the engaging portion 39, while the engaging portion 39 is provided on the side wall of the support portion 34. An engagement hole 36 is formed at a place where the engagement protrusion 40 can be engaged when the support portion 34 is provided around the outer periphery. Further, the engagement protrusion 40 has such a length that it can be pulled out of the engagement hole 36 by applying a force in the direction of rotation to the engagement portion 39, thereby rotating the engagement portion 39. Thus, the engaging portion 39 can be fixed to the support portion 34 by engaging the engaging protrusion 40 with the engaging hole 36, and the engaging portion 39 rotates with respect to the support portion 34. It is free.

  In the drawing, a plurality of tooth-shaped protrusions 37 of gears are formed on the outer periphery of the support portion 34 in the present embodiment in a direction parallel to the axial direction of the support portion 34. As a result, in a state where the engaging protrusion 40 is disengaged from the engaging hole 36, the engaging protrusion 39 is engaged between the protrusions 37, so that the engaging portion 39 rotates. It is possible to prevent this.

  Next, in FIGS. 7 and 8, reference numeral 41 denotes a connecting portion. That is, in the present embodiment, a connecting portion 41 is continuously provided on the engaging portion 39 toward the outer peripheral side. And the wind direction adjustment board 42 is attached to the front-end | tip of this connection part 41, and the wind direction adjustment tool 31 in a present Example is comprised by this.

  Here, the wind direction adjusting plate 42 will be described. In the present embodiment, the wind direction adjusting plate 42 has a plate shape curved in an arc shape, and the engaging portion 39 is rotated with respect to the support portion 34. Thus, it is possible to rotate the air volume adjusting plate 9 so as to draw a circle on the back surface.

  Therefore, by rotating the wind direction adjusting plate 42 and, for example, arranging the wind direction adjusting plate 42 on the side where strong wind is not desired to enter the room, it is possible to prevent the wind from entering the room from the side.

  As shown in the figure, in the present embodiment, the connecting portion 41 has a base end portion of an elongated plate-like material connected to the engaging portion 39, and a tip portion of the plate-like material is Although it is attached to the wind direction adjusting plate 42 as a deformed ring having an arc shape corresponding to the inner wall of the wind direction adjusting plate 42, it is not necessarily limited to this shape as long as the wind direction adjusting plate 42 can be continuously provided. .

  Next, reference numeral 43 in the figure denotes a guide. In other words, in the present embodiment, the wind direction adjusting plate 42 slides on the back surface of the air volume adjusting plate 9 on the outer side of the portion where the wind direction adjusting plate 42 rotates, or the ring direction adjusting plate 42 rotates in the vicinity. The guide 43 is formed so that the wind direction adjusting plate 42 can be stably rotated and arranged. Therefore, the guide 43 has a height that can support the wind direction adjusting plate 42 from the outer peripheral side, and further, when the air volume adjusting plate 9 is pushed into the main body 2 side, it collides with the lever 17. To avoid it, a part is cut out.

  Next, in FIGS. 5, 6, and 9, reference numeral 44 denotes an insertion portion continuously provided on the base end side of the slider 10. That is, as described above, in this embodiment, the slider 10 protrudes from the back surface of the air volume adjusting plate 9 toward the main body 2 side. At this time, in this embodiment, the slider 10 is attached to and detached from the support portion 34. The slider 10 is projected from the back surface of the air volume adjusting plate 9 by being freely attached.

  Explaining this relationship, in the present embodiment, a pair of locking projections 38 are formed so as to face the inner peripheral side of the support portion 34, while the base end of the slider 10 A cylindrical insertion portion 44 having an outer diameter that can be inserted into the support portion 34 is provided continuously, and a locking groove 45 in which the locking projection 38 is locked is formed in the insertion portion 44. Then, the slider 10 is protruded on the back surface of the air volume adjusting plate 9 by inserting the insertion portion 44 into the support portion 34 while locking the locking projection 38 in the locking groove 45.

  Further, in the present embodiment, the locking groove 45 is continuously provided in an insertion groove portion 4501 formed in a direction parallel to the axial direction of the slider 10, and in a direction orthogonal to the axial direction of the slider 10 at the distal end portion of the insertion groove portion 4501. The locking groove portion 4502 has a key shape, and when the locking protrusion 38 is locked to the locking groove 45, the locking protrusion 38 is first inserted into the insertion groove portion 4501 and is directly advanced to the tip portion. Go. Then, after the locking projection 38 reaches the tip of the insertion groove portion 4501, the slider 10 is rotated to insert the locking projection 38 into the fixed groove portion 4502, and the locking projection 38 is fixed to the fixed groove portion. The slider 10 is rotated until it reaches the innermost part 4502. Then, the insertion portion 44 can be inserted and fixed in the support portion 34 in a state where the locking projection 38 is locked in the locking groove 45, and the slider 10 can be prevented from coming out of the support portion 34.

  Next, the operation of the vent cover 1 of this embodiment configured as described above will be described. In the state of FIG. 1, the slider 10 is inserted to the innermost part of the slider receiving portion 5, and the stopper 13 is locked. The claw portion 15 is locked in the locking recess 11 on the foremost side of the slider 10, and the air volume adjusting plate 9 is in a state where the indoor side opening 201 of the main body portion 2 is fully closed. The slider 10 is urged by the spring 12 in a direction to be removed from the slider receiving portion 5, and pressure is applied to the slider 10 in a direction to be removed from the inside of the slider receiving portion 5. Since the locking of the locking recess 11 and the locking claw 15 is not released, the slider 10 cannot be removed from the slider receiving portion 5 unless the stopper 13 is operated. The move can not be opened aperture 201 of the indoor side of the main body portion 2.

  Next, when the stopper main body 14 is moved to the distal end side via the lever 17 by pressing the pressing portion 18 toward the center of the main body 2 in the state of FIG. While moving in the protruding direction, the locking recess 11 of the slider 10 and the locking claw 15 are unlocked.

  Then, since the slider 10 is biased by the spring 12 in the direction to come out of the slider receiving part 5, it moves in the direction to come out from the slider receiving part 5, and thereby the air volume adjusting plate 9 moves to the indoor side. Then, the indoor side opening 201 of the main body 2 is opened. As a result, outside air can be taken into the room, and the filter 19 captures foreign matter such as dust flowing into the main body together with the outside air, thereby preventing the entry of foreign matter such as dust into the room. Can do. In addition, by intermittently pressing the pressing portion 18, the slider 10 is extended stepwise and the air volume adjusting plate 9 is moved stepwise to the indoor side, so that the indoor side opening 201 of the main body portion 2 is stepwise. You can open up to.

  On the other hand, by pressing the pressing portion 18 for a relatively long time, the slider 10 is extended to the longest and the air volume adjusting plate 9 is moved to the indoor side in one operation, thereby opening the indoor side opening 201 of the main body portion 2. It is possible to fully open at once, and this fully open state is shown in FIG. At this time, the spring 12 that is biased in the direction of pulling out the slider 10 is adjusted so that the slider 10 does not come out of the slider receiving part 5 when the air volume adjusting plate 9 is fully opened, or the slider receiving is received. The part 5 may be provided with a stopper for controlling the movement of the slider 10.

  In this state, by rotating the wind direction adjusting plate 42, the direction of the wind entering the room can be adjusted, and the wind direction adjusting tool 31 in this embodiment is provided on the back surface of the air volume adjusting plate 9. An engaging portion 39 that is rotatably provided on the outer peripheral side of the support portion 34 that protrudes from the support portion 34, a connecting portion 41 that is connected to the engaging portion 39 in the direction of the peripheral edge of the air volume adjusting plate 9, Since the plate-shaped wind direction adjusting plate 42 formed in an arc shape connected to the connecting portion 41 is configured, the wind direction adjusting plate 42 can be easily rotated to place the wind direction adjusting plate 42 at a desired location. Is possible.

  Next, when the pressure is applied in the direction in which the slider 10 is inserted into the slider receiving portion 5 by pushing the air volume adjusting plate 9 toward the wall side in the fully opened state of FIG. 2, as described above, the principle of the wedge Thus, the latching of the latching recess 11 and the latching claw 15 can be released, and the slider 10 can be inserted into the slider receiving part 5. Therefore, the air volume adjusting plate 9 is moved to the wall side and the main body 2. It is possible to close the indoor side opening 201. At that time, by pushing the air volume adjusting plate 9 stepwise toward the wall, the locking claw portion 15 is locked to the locking recess 11 stepwise, and the indoor side opening 201 of the main body portion 2 is stepped stepwise. In addition to being able to close, the air volume adjusting plate 9 is pushed to the wall side at once, thereby locking the locking claw portion 15 to the locking recess 11 on the foremost side and opening the indoor side opening 201 of the main body portion 2. It is possible to fully close at once. This fully closed state is the state shown in FIG. 1. In this state, as described above, even if the air volume adjusting plate 9 is pushed in, the fully closed state is not released and the air volume adjusting plate 9 is moved as long as the stopper 13 is not operated. Thus, the opening 201 on the indoor side of the main body 2 cannot be opened.

  Thus, in the ventilation port cover 1 of the present embodiment, by pushing the air volume adjusting plate 9 into the main body side, the indoor side opening of the main body portion can be closed stepwise or at once, and the stopper can be used. By operating, the indoor side opening of the main body can be opened stepwise or all at once, and the air volume adjusting plate 9 cannot be moved unless the stopper is operated. In the process of fully closing the indoor side opening, it is possible to reliably prevent the indoor side opening of the main body from opening by pushing the air volume adjusting plate 9 too much.

  Further, in the ventilation port cover of the present embodiment, the wind direction adjusting tool is provided on the main body side of the air volume adjusting plate, and the air direction adjusting tool is provided in a projecting manner on the main body side of the air volume adjusting plate. An engagement portion that is rotatably provided on the outer peripheral side, a connection portion that is provided continuously with the engagement portion, and an arc-shaped wind direction adjusting plate that is provided continuously with the connection portion. By rotating the engaging portion, the wind direction adjusting plate can be arranged at any position on the peripheral portion of the air volume adjusting plate, so that the direction of the wind taken into the room can be adjusted by this wind direction adjusting plate, and At this time, it is possible to easily finely adjust the position of the wind direction adjusting plate.

  The second embodiment of the vent cover according to the present invention will be described with reference to the drawings. The vent cover of the present embodiment is characterized by the structure of the stopper, and the other configurations are the same as those of the above-described embodiment. Only the relationship between the slider, the slider receiving portion and the stopper will be described, and the description of the other portions will be omitted. Further, the slider 10 is a diagram in which the insertion portion 44 is omitted.

  In the stopper of this embodiment, when the air volume adjusting plate 9 is attached to the slider 10, it is possible to prevent the slider 10 from moving in the direction in which the slider 10 is inserted into the slider receiving portion 5. That is, in the ventilation port cover 1 of the present embodiment, the slider 10 is detachably protruded from the air volume adjusting plate 9 via the support portion 34 as in the above-described embodiment. When assembling the cover 1 or after removing the air flow adjusting plate 9 for cleaning, the air flow adjusting plate 9 may be attached to the slider 10 again.

  However, at this time, the stopper 13 in this embodiment allows the slider 10 to move in the direction in which it is inserted into the slider receiving portion 5 even when the locking claw 15 is locked to the locking recess 11. When the air volume adjusting plate 9 is attached to the slider 10, if the slider 10 is pushed in, the slider 10 moves to the slider receiving portion 5 side, and the air volume adjusting plate 9 may not be attached smoothly. Therefore, in the stopper of this embodiment, the slider 10 can be prevented from moving in the direction in which the slider 10 is inserted into the slider receiving portion 5.

  12 to 14 are views showing the relationship between the slider, the slider receiving portion and the stopper in the second embodiment. FIG. 12 shows the slider 10 inserted in the slider receiving portion 5 and the slider. 10 shows a state in which the locking claw 15 of the stopper 13 is locked to the locking recess 11 of FIG. 10. FIG. 13 is an exploded view of the slider receiving portion 5, the slider 10, and the stopper 13. is there.

  The stopper 13 in this embodiment has a second locking claw portion 47 protruding above the spring 16 toward the locking claw portion 15 via the mounting portion 46. On the other hand, on the surface of the slider 10 that faces the second locking claw portion 47, a second locking recess is formed at a position that faces the second locking claw portion 47 when the slider 10 is extended to the longest. 48 is formed. A locking claw through-hole 49 through which the second locking claw portion 47 passes is formed on the surface of the slider receiving portion 5 that faces the second locking claw portion 47.

  In addition, the second locking claw portion 47 is not locked to the second locking recess 48 in a state where the locking claw portion 15 and the locking recess 11 are locked, and the pressing portion 18. In the state immediately after the locking recess 11 of the slider 10 and the locking claw 15 are unlocked by pushing the lever toward the center of the body 2 and moving the stopper body 14 to the tip side via the lever 17. The second locking claw 47 is not locked to the second locking recess 48, and in a state immediately after the locking recess 11 of the slider 10 and the locking claw 15 are released, The stopper body 14 is set to a length that is locked to the second locking recess 48 by moving the stopper body 14 toward the distal end side.

  Furthermore, when the slider 10 is about to move toward the slider receiving portion 5, the second locking claw portion 47 and the second locking recess 48 come into contact with each other to prevent the slider 10 from moving. It is in form. That is, the relationship between the locking claw 15 and the locking recess 11 is opposite.

  That is, the second locking recess 48 is formed on the side surface of the slider 10 obliquely upward from the horizontal plane 50 formed in the direction perpendicular to the longitudinal direction of the slider 10 from the side surface of the slider 10 and the innermost portion of the horizontal plane 50. It is formed by the taper surface 51 formed in the direction.

  On the other hand, the second locking claw portion 47 has a horizontal surface 52 that contacts the horizontal surface 50 of the second locking recess 48 and a tapered surface 53 that contacts the tapered surface 51 of the second locking recess 48. Yes. Accordingly, in a state where the second locking claw portion 47 is locked to the second locking recess 48, if pressure is applied to the slider 10 in the direction in which it is inserted into the slider receiving portion 5, The horizontal surface 50 of the locking recess 48 applies a pressure in the direction in which the slider 10 tends to move toward the slider receiving portion 5 to the horizontal surface 52 of the second locking claw portion. Since it is movable only in the direction orthogonal to the longitudinal direction of the receiving portion 5 and the pressure is applied to the horizontal surface 52 of the second locking claw portion 47 by the horizontal surface 50 of the second locking recess 48, the locking recess 11 Therefore, the principle of rust does not work as in the relationship with the locking claw 15, so that the locking of the second locking recess 48 and the second locking claw portion 47 is not released, and the slider 10 is moved to the slider receiving portion 5. Inserted into It is prevented to move to that direction.

  Accordingly, in the stopper of the present embodiment, when the air volume adjusting plate 9 is attached to the slider 10, even if the slider 10 is pushed by the air volume adjusting plate 9, the slider 10 moves to the slider receiving portion 5 side. The air volume adjusting plate 9 can be easily attached to the slider 10.

  Next, the relationship between the slider 10, the stopper 13 and the slider receiving portion 5 in this embodiment will be described with reference to FIG. 14. FIG. 14 (a) shows the locking recess in the state where the slider 10 is extended to the longest. 11 is a cross-sectional view showing a state where the locking claw portion 15 is locked to the second locking claw portion 15. In this state, the second locking claw portion 47 and the second locking recess portion 48 are not locked. When the slider 10 is pushed into the slider receiving portion 5 side, the slider 10 moves to the slider receiving portion 5 side.

  Next, FIG. 14B shows a state where the pressing portion 18 is pushed toward the center side of the main body portion 2 and the stopper main body 14 is moved to the distal end side via the lever 17 to engage with the locking concave portion 11 of the slider 10. It is sectional drawing which showed the state immediately after releasing the latching | locking of the nail | claw part 15, The 2nd latching claw part 47 and the 2nd latching recessed part 48 are not latched also in this state, Therefore, a slider When 10 is pushed into the slider receiving portion 5 side, the slider 10 moves toward the slider receiving portion 5 side.

  In the state of FIG. 14B, the second locking claw portion 47 is further moved by pushing the pressing portion 18 toward the center of the main body 2 and moving the stopper main body 14 toward the distal end via the lever 17. Passes through the locking claw through-hole 49 and is locked by the second locking recess 48, so that even when the slider 10 is pushed to the slider receiving portion 5 side, the slider 10 is moved to the slider receiving portion 5 side. It becomes possible to prevent moving to. This state is shown in FIG.

  Therefore, in the vent cover 1 of the present embodiment, when the air volume adjusting plate 9 is attached to the slider 10 with the slider 10 extended to the longest, the engagement between the engagement recess 11 and the engagement claw portion 15 of the slider 10. After releasing the stop, the stopper body 14 is further moved to the distal end side, and the second locking claw portion 47 is locked to the second locking recess 48 so that the slider 10 is pushed by the air volume adjusting plate 9. Even in this case, the slider 10 can be prevented from moving to the slider receiving portion 5 side, and the air volume adjusting plate 9 can be easily attached to the slider 10.

  The second locking claw portion 47 does not necessarily have to be provided above the spring 16 and may be provided at any position as long as it can be locked to the second locking recess 48. . Therefore, for example, it may project toward the locking claw 15 via the mounting portion 46 below the spring 16, or on both inner sides of the stopper body 14 facing the longitudinal direction of the spring 16. Or you may arrange | position to one side. In this case, the through-holes 49 for the engaging claws and the locations where the second engaging concave portions 48 are formed are also locations facing the second engaging claw portions 47.

  The third embodiment of the vent cover according to the present invention will be described with reference to the drawings. The vent cover of the present embodiment is characterized by the configuration of the stopper, and the other configurations are the same as those of the previous embodiment. Only the relationship between the slider, the slider receiving portion and the stopper will be described, and the description of the other portions will be omitted. Further, the slider 10 is a diagram in which the insertion portion 44 is omitted.

  15 to 17 are sectional views showing the relationship between the slider, the slider receiving portion and the stopper in the third embodiment. In the figure, 21 is the stopper, 10 is the slider, and 5 is the slider receiving portion. is there.

  In this embodiment, the stopper 21 has a stopper main body 22 having a locking claw 23 which is locked to the locking recess 11 formed in the slider 5 at the tip, and the stopper main body 22 is , And is supported in the built-in portion 30 formed in the stopper receiving portion 5. In addition, the stopper main body 22 is pivotable in both the direction in which the locking claw 23 is locked to the locking recess 11 and the direction in which the locking is released. The locking claw 23 is always urged in the direction in which the locking claw 23 is locked to the locking recess 11.

  A lever 25 is disposed on the proximal end side of the stopper main body 22, and the lever 25 has a distal end abutting on or close to the proximal end side of the stopper main body 22. By pushing the base end of the main body 22, the stopper main body 22 rotates in the direction in which the locking claw 23 is released from the locking recess 11.

  The lever 25 is urged by a spring 27 in a direction to release the contact or proximity between the distal end portion and the proximal end side of the stopper main body 22. The slider 10 is locked in the locking recess 11.

  The lever 25 is branched into a pressing piece 28 that presses the proximal end side of the stopper main body 22 and a biased piece 29 that is biased by a spring 27. The pressing piece 28 and the biased piece 29 are separated from each other. , And penetrates the side wall of the built-in part 30 and is located in the built-in part 30. That is, the spring 27 is interposed between the inner wall of the slider receiving portion 5 and the biased piece 29 in the built-in portion 30.

  On the other hand, in the present embodiment, the slider 10 is inserted into the slider receiving portion 5 in such an arrangement that the locking concave portion 11 faces the built-in portion 30 side of the slider receiving portion 5, and is similar to the above-described embodiment. The spring 12 urges the slider receiving portion 5 in the direction of removal.

  Further, the locking recess 11 in the present embodiment also has a horizontal plane 1101 formed in a direction orthogonal to the longitudinal direction of the slider 10 from the side surface of the slider 10 and the innermost portion of the horizontal plane 1101, as in the previous embodiment. A tapered surface 1102 formed obliquely downward is formed. The locking claw 23 also has a horizontal surface that contacts the horizontal surface 1101 of the locking recess 11 and a tapered surface that contacts the tapered surface 1102 of the locking recess 11. When pressure in the direction of insertion into the portion 5 is applied, the stopper body 22 rotates in the direction in which the locking recess 11 and the locking claw 23 are released according to the principle of the wedge, whereby the slider 10 is Insert into the slider receiver 5.

  On the other hand, when a pressure is applied to the slider 10 in the direction of coming out of the slider receiving portion 5, a downward pressure is applied to the horizontal surface of the locking claw by the horizontal surface 1101 of the locking recess 11. At this time, since the stopper main body 22 has a turning locus in the direction in which the locking claw 23 is locked to the locking recess 11, the slider 10 is pressed against the inner wall of the slider receiving portion 5 by the stopper main body 22. Then, the slider 10 is in a fixed state against the urging force of the spring 12, the locking of the locking recess 11 and the locking claw 15 is maintained without being released, and the slider 10 comes out of the slider receiving unit 5. It cannot move in the direction.

  Therefore, the stopper 21 in this embodiment also prevents the slider 10 from moving in the direction of coming out of the slider receiving portion 5 in a state where the locking claw 23 is locked to the locking recess 11, and the slider The movement of 10 in the direction of insertion into the slider receiving portion 5 is allowed.

  Next, the operation of the stopper 21 in this embodiment will be described. In the state shown in FIG. 15, the slider 10 is inserted to the innermost part of the slider receiving portion 5, and the locking claw portion 15 of the stopper 21 is the innermost portion of the slider 10. The air flow adjusting plate 9 is locked in the locking recess 11 on the front end side, and the indoor side opening 201 of the main body 2 is fully closed. In this state, the slider 10 is urged by the spring 12 in the direction in which the slider 10 is removed from the slider receiving portion 5, and pressure is applied to the slider 10 in the direction in which the slider 10 is removed from the slider receiving portion 5. Since the locking of the locking recess 11 and the locking claw 15 is not released, the slider 10 cannot be removed from the slider receiving portion 5 unless the stopper 21 is operated, and therefore the air volume adjusting plate 9 is moved to move the main body. The opening 201 on the indoor side of the part 2 cannot be opened.

  Next, in the state of FIG. 15, by pressing the pressing portion 26 toward the slider receiving portion 5, the stopper main body 22 is moved through the lever 25 in the direction in which the locking claw portion 23 and the locking recess 11 are unlocked. When it rotates, the locking recess 11 of the slider 10 and the locking claw 23 are unlocked.

  Then, since the slider 10 is biased by the spring 12 in the direction to come out of the slider receiving part 5, it moves in the direction to come out from the slider receiving part 5, and thereby the air volume adjusting plate 9 moves to the indoor side. Then, the indoor side opening 201 of the main body 2 is opened. At that time, by intermittently pressing the pressing portion 26, the slider 10 is extended stepwise, and the air volume adjusting plate 9 is moved stepwise to the indoor side, thereby opening the indoor side opening 201 of the main body portion 2 stepwise. Can be released.

  On the other hand, by pressing the pressing portion 26 for a relatively long time, the slider 10 is extended to the longest and the air volume adjusting plate 9 is moved to the indoor side by one operation, thereby opening the indoor side opening 201 of the main body portion 2. It is possible to fully open at once. FIG. 17 shows the fully opened state, and FIG. 16 shows a process in which the slider 10 extends. At this time, the spring 12 that is biased in the direction of pulling out the slider 10 is adjusted so that the slider 10 does not come out of the slider receiving part 5 when the air volume adjusting plate 9 is fully opened, or the slider receiving is received. The part 5 may be provided with a stopper for controlling the movement of the slider 10.

  In this state, the direction of the wind entering the room can be adjusted by rotating the wind direction adjusting tool 19 as in the case of the above-described embodiment, and not only the wind direction but also the air volume. Can be finely adjusted.

  Next, when the pressure is applied in the direction in which the slider 10 is inserted into the slider receiving portion 5 by pushing the air volume adjusting plate 9 toward the wall in the fully opened state of FIG. 11 and the latching claw 23 are unlocked, and the slider 10 can be inserted into the slider receiving portion 5. Accordingly, the air volume adjusting plate 9 is moved to the wall side to open the indoor side opening 201 of the main body portion 2. Can be closed. At that time, by pushing the air volume adjusting plate 9 stepwise toward the wall, the locking claw portion 23 is locked to the locking recess 11 stepwise, and the indoor side opening 201 of the main body 2 is stepped stepwise. In addition to being able to close, the air volume adjusting plate 9 is pushed to the wall side at a stroke, so that the locking claw 23 is locked to the locking recess 11 on the foremost side, and the indoor opening 201 of the main body 2 is opened. It is possible to fully close at once. As described above, this fully closed state is the state shown in FIG. 15. In this state, even if the air volume adjusting plate 9 is pushed in, the fully closed state is not released, and unless the stopper 25 is operated, the air volume adjusting plate 9 is moved. It cannot be moved and the opening 201 on the indoor side of the main body 2 cannot be opened.

  As described above, even in the ventilation port cover 1 of the present embodiment, by pushing the air volume adjusting plate 9 into the main body side, the indoor side opening of the main body portion can be closed stepwise or at a time, and the stopper can be used. By operating, the indoor side opening of the main body can be opened stepwise or at once, and the air volume adjusting plate cannot be moved unless the stopper is operated. In the process of fully closing the inner opening, it is possible to reliably prevent the indoor opening of the main body from opening by pushing the air volume adjusting plate too much.
