JP 2010-255388 A

  By the way, in the door of patent document 1, it is necessary to attach a coating | cover board to the connection material (beam member) which is a structural member by the side of a door. For this reason, at the time of construction of a door, it is difficult to reduce the number of construction steps because it is necessary to set a process of attaching the cover plate separately from the process of attaching the louver blades.

  An object of the present invention is to provide a movable louver and joinery that can prevent light leakage at the end portion of the louver and can be easily constructed.

  The movable louver of the present invention includes a louver body, an attachment body attached to an end of the louver body, and a support body that rotatably supports the attachment body, and the attachment body is attached to the support body. A first light-shielding protrusion formed so as to protrude toward the mounting body, and the support includes a second light-shielding protrusion formed so as to protrude toward the mounting body. The mounting body is positioned to overlap the second light-shielding protrusion in a state where the mounting body is in a closed position with respect to the support.

According to the movable louver of the present invention, for example, when the movable louver installed in the ventilation opening formed in the door or the like is positioned at the closed position of the opening, the attachment body is positioned at the closed position with respect to the support. Since the first light-shielding protrusion and the second light-shielding protrusion overlap, it is possible to prevent light from leaking from between the attachment body and the support body.
In addition, since the movable louver itself includes the first light-shielding protrusion and the second light-shielding protrusion, in addition to the attachment of the movable louver, it is not necessary to attach a cover plate for preventing light leakage to the door, etc. The construction process can be reduced and movable louvers can be easily constructed.

In the movable louver of the present invention, it is preferable that the movable louver has a restricting portion that is formed on the attachment body and the support body and restricts a maximum rotation angle of the attachment body with respect to the support body.
According to such a configuration, by restricting the maximum rotation angle of the attachment body with respect to the support body by the restriction portion, it is possible to set the open state of the opening by the movable louver installed in the opening of the door or the like. The direction of the movable louver can be set in the open area or the open state of the opening.

In the movable louver of the present invention, the first light-shielding protrusion and the second light-shielding protrusion have contact surfaces that contact each other when the attachment body is in a closed position with respect to the support, The restricting portion has a restriction contact surface formed on the attachment body and a restriction receiving surface formed on the support body, and the restriction contact surface is in a closed position of the attachment body with respect to the support body. In a certain state, it is preferable that the mounting body is inclined so as to be separated from each of the contact surfaces as the mounting body is separated from the rotation axis with respect to the support body.
According to such a configuration, when the attachment body rotates from the closed position with respect to the support body, the first light shielding protrusion is inclined with respect to the second light shielding protrusion. Since the mounting body is inclined so as to be separated from the abutment surface as it is separated from the rotation axis with respect to the support body, the contact surface and the contact surface can be brought into contact with each other at the maximum rotation position. The rotation of the movable louver can be regulated stably.

In the movable louver of the present invention, one of the attachment body and the support body has an engaging portion, and the other of the attachment body and the support body has an engaged portion. And it is preferable that the said engaging part is comprised so that it can engage with the said to-be-engaged part when the said attachment body is located in a closed position with respect to the said support body.
According to such a configuration, the closed state of the movable louver can be maintained by the engagement between the engaging portion and the engaged portion. For example, when a movable louver is installed at the opening of a door, the movable louver is subjected to a rotational force applied to the movable louver by the vibration of the door, or the movable louver receives gas pressure when the door is opened or closed. May rotate unintentionally. In order to prevent such unintentional opening and turning of the movable louver, it is conceivable to increase the rotation resistance of the attachment body relative to the support. However, if this rotation resistance is increased, the operation of the movable louver becomes heavy. . Therefore, the closed state of the movable louver can be maintained without increasing the operation of the movable louver by engaging the engaged portion with the engaging portion when the attachment body is located at the closed position with respect to the support body. .

In the movable louver of the present invention, a shaft body is formed on one of the attachment body and the support body, and the shaft body is rotated on the other of the attachment body and the support body. A bearing body that is movably supported is formed, and the first light-shielding protrusion and the second light-shielding protrusion are respectively provided by a pair of protrusions that are provided point-symmetrically with respect to the center of the shaft and the bearing body. Preferably, the ends of each of the pair of protrusions are provided at positions that overlap the bearing body in the thickness direction of the attachment body and the support body.
According to such a configuration, when the mounting body is in the closed position with respect to the support body, the end portions of each pair of protrusions overlap the bearing body, and therefore there is a gap between each pair of protrusions and the shaft portion. Is not formed. For this reason, it can prevent that light leaks from between each pair of protrusion part and a bearing body.

In the movable louver of the present invention, a shaft body is formed on one of the attachment body and the support body, and the shaft body is rotated on the other of the attachment body and the support body. A bearing body that is movably supported is formed, and a peripheral surface of one of the shaft body and the bearing body has an uneven shape along a circumferential direction of the shaft body, and the shaft body and the bearing It is preferable that either one of the bodies is formed with a flexible latching portion that comes into contact with the peripheral surface of the shaft body.
According to such a structure, when the latching part of a bearing body is located in the recessed part of the surrounding surface of a shaft body, the retention force which hold | maintains the rotation angle with respect to the support body of an attachment body arises. Further, when turning force is applied to the attachment body by manual operation, the latching portion is bent and disengaged from the concave portion of the peripheral surface of the shaft body, so that the attachment body can be rotated. Thereby, the rotation angle of every fixed space | interval can be hold | maintained, although the rotation operation of an attachment body is possible.

The joinery of the present invention includes a shoji in which an opening is formed, and the above-described movable louver of the present invention that is rotatably provided in the opening of the shoji.
According to the joinery of the present invention, the same effect as the above-described movable louver of the present invention is exhibited.

[Construction of movable louvers]
Hereinafter, the construction procedure of the movable louver 3 will be described.
First, the movable louver 3 is assembled. Specifically, two combinations 5 are prepared for one louver body 4. Next, both end portions of the louver body 4 are inserted into the fitting groove portions 54 of the cap bodies 50, and set screws (not shown) are threaded through the holes 55 and screwed into the screw holes 41 of the louver body 4. The main body 50 is attached to the louver main body 4. Subsequently, the shaft main body 511 of each cap main body 50 is inserted into the shaft hole 614 of each cap receiving body 60, and the cap main body 50 is rotatably connected to the cap receiving body 60.
Here, the concave portion of the concavo-convex outer peripheral surface 511 </ b> A of the shaft main body 511 is engaged with the latching portion 613 of the cap receiver 60. For this reason, when the latching | locking part 613 is located in the recessed part of 511 A of outer peripheral surfaces of the shaft main body 511, the retention strength which hold | maintains the rotation angle with respect to the cap receiver 60 of the cap main body 50 arises. Further, when turning force is applied to the cap body 50 by manual operation, the latching portion 613 is bent and disengages from the concave portion of the outer peripheral surface 511A of the shaft body 511, so that the cap body 50 can be rotated. Thereby, the rotation angle of the cap body 50 at a predetermined interval (in this embodiment, the rotation angle of every 30 °) can be held while the cap body 50 can be rotated.
In this way, two movable louvers 3 are assembled according to the number of openings 21 of the door body 2.

Next, each movable louver 3 is attached to the door body 2. Specifically, the extension piece 612 and the insertion protrusion 64 of each cap receiver 60 are inserted into the holding hole 241 and the insertion hole 242 of each connection member 24, and the connection member 24 located on the lower end side of the upper movable louver 3. And a connecting member 24 positioned on the upper end side of the lower movable louver 3 are fitted into the intermediate rail 22 to constitute a combination of two movable louvers 3. Subsequently, this combination is disposed in the opening 21 of the door body 2 and is sandwiched by the frame 23 from the outside of the room. Then, the frame 23 is screwed to the door body 2.
In this way, each movable louver is attached to the door body 2 to constitute the indoor door 1.

[Operation of movable louver]
Hereinafter, the opening / closing operation | movement of the movable louver 3 is demonstrated.
1 to 4 show a state in which the movable louver 3 is in the closed position of the opening 21, and FIG. 3 shows a state in which the movable louver 3 is in the maximum open position in which the opening 21 is fully opened by turning 90 degrees. The state which exists in the maximum rotation position which the movable louver 3 rotated to the maximum is shown. In FIG. 3, the movable louver 3 in the closed position is indicated by a solid line, and the movable louver 3 in the maximum open position is indicated by a two-dot chain line with the reference numeral 3A. The movable louver 3 in a state of being in the moving position is denoted by a two-dot chain line with reference numeral 3B.

The opening operation of the movable louver 3 is as follows. When the movable louver 3 in the closed position is manually operated, the louver body 4 and the cap body 50 rotate in the R direction (opening direction) about the rotation axis 57 with respect to the cap receiver 60. At this time, the engaged claw portion 53 is removed from the engaging claw portion 63, and each extending portion 42 of the louver main body 4 is separated from the airtight material 252 of each door stop material 25. Therefore, the opening 21 starts to be opened and is movable. Louver 3 is inclined with respect to door body 2.
Subsequently, when the louver main body 4 and the cap main body 50 are rotated 90 degrees in the R direction, the louver main body 4 and the cap main body 50 reach the maximum open position, and the open area of the opening 21 becomes the most expanded state.
Further, when the louver main body 4 and the cap main body 50 are rotated in the R direction, the open area of the opening 21 is narrowed, the movable louver 3 is inclined in the opposite direction to the aforementioned inclination, and the airflow guiding direction is also opposite. . When the louver main body 4 and the cap main body 50 reach the maximum rotation position, the restriction contact surfaces 524 of the first light shielding protrusions 52 come into contact with the restriction receiving surfaces 624 of the second light shielding protrusions 62, and the louver main body 4. Further, the rotation of the cap body 50 in the R direction is restricted.
In this way, the movable louver 3 performs an opening operation.

The closing operation of the movable louver 3 is as follows. When the movable louver 3 in the maximum rotation position is rotated in the closing direction by manual operation, the louver body 4 and the cap body 50 reach the closed position through the maximum open position. When the louver main body 4 and the cap main body 50 reach the closed position, the engaged claw portion 53 engages with the engaging claw portion 63, and each extending portion 42 of the louver main body 4 is an airtight material for each door stop material 25. The first light-shielding protrusion 52 is in contact with the second light-shielding protrusion 62 and shields light that is about to pass between the cap body 50 and the cap receiver 60.
In this way, the movable louver 3 performs a closing operation.

[Effect of this embodiment]
(1) When the cap body 50 is located at the closed position with respect to the cap receiver 60, the first light-shielding protrusion 52 and the second light-shielding protrusion 62 overlap with each other. It is possible to prevent light from leaking from between.
Further, since the movable louver 3 itself includes the first light shielding protrusion 52 and the second light shielding protrusion 62, in addition to the attachment of the movable louver 3, a cover plate for preventing light leakage is attached to the door body 2.
