Describes a movable louver type shutter in which the bar member pin-coupled to the first transmission member is advanced and retracted, and the louver is rotated, that is, opened and closed via the second transmission member.

  However, in Patent Document 1, it is necessary to rotate the first transmission member by the rotation shaft and convert the rotation of the first transmission member into the movement of the bar member in the advancing / retreating direction. In addition, it is necessary to further convert the forward / backward movement of the bar member into the rotation of a plurality of louvers. Further, since large resistance and frictional force act on these operations, there is a problem that a large force is required for opening and closing the louver by operating the slider.

  In order to solve the problem relating to Patent Document 1, the applicant of Patent Document 2 is equipped with an opening / closing mechanism that opens and closes the louver by advancing and retracting the connecting member by rotating an operation unit facing the indoor side. A movable louver type shutter is proposed. Specifically, the opening / closing mechanism includes a rotary shaft member having an operation portion, a screw member that rotates forward and backward through a gear train when the rotary shaft member rotates forward and backward, and the screw member that rotates forward and backward.

The louver can be rotated through the piece. That is, since the conversion between the linear movement in the forward / backward direction and the movement in the rotational direction in which a large resistance or frictional force is generated is only the opening / closing portion of the louver, the force required for opening / closing the louver by operating the operation member is reduced. be able to. Moreover, the opening / closing (link) mechanism is composed of an operation member having a guide groove extending in the horizontal direction and inclined in the vertical direction and a link member extending in the vertical member, so that the configuration can be simplified and assembly workability can be improved. It can improve and cost reduction.

A louver rotated by a member is disposed, the operation member is disposed in the vicinity of the second vertically long member, and a locking portion of the link member is disposed in a pair of the second vertically long members. It is preferable to lock the connecting member. If it does in this way, a link member can be comprised by the rod-shaped member extended linearly. As a result, the operating force of the operating member can be applied as a louver opening / closing operating force without waste.

It is preferable that the opening operation direction and the closing operation direction of the second operation member to be operated are the same. In this way, the user's opening / closing operability can be improved.

  Moreover, it is preferable that the first and second operating members are provided at positions adjacent to each other in the vertical direction, and the movement distances in the horizontal direction substantially coincide with each other at the same rotation angle of the first louver and the second louver. . If it does in this way, the convenience at the time of adjusting the rotation angle of the 1st louver or the 2nd louver which a user will be located in the side far from a line of sight in the shutter long in the vertical direction can be improved.

  In the movable louver type shutter according to the present invention, since the conversion between the linear movement and the movement in the rotational direction, which is a large resistance, is only the opening and closing part of the louver, the operation force for opening and closing the louver by operating the operation member is very high.

  The louvers 27A and 27B that are opened and closed by the opening and closing mechanism are formed in accordance with the lengths of the vertical rods 11A and 11B and the intermediate rods 13A and 13B and the interval between them, and are fixed to both ends via fixing pieces 28A and 28B. A vertical frame member 19 is provided. In addition, connecting members 34A and 34B are disposed inside each vertical frame member 19, and fixed pieces 28A and 28B are connected to the connecting members 34A and 34B, respectively. And in this state, it is made to fit in mounting part 15A, 18, 18, 15B of vertical hook 11A, 11B and intermediate hook 13A, 13B.

  Thereafter, the openings 53 of the operation members 48A and 48B and the through holes 26 of the intermediate rail 14 are moved so as to coincide with each other in the vertical direction. In this state, the engagement protrusions of the link members 37A and 37B are inserted into the guide groove 52. After inserting the portion 38, the metal locking rod 43 of the locking portion 39 is inserted into the locking holes 36 of the connecting members 34A, 34A, 34B, 34B located in the intermediate collars 13A, 13B and locked. Can be assembled.

  As described above, the opening / closing mechanism of the louvers 27A and 27B in the shutter 10 according to the present invention is operated with the link members 37A and 37B in order to move the connecting members 34A and 34B connecting the fixed pieces 28A and 28B similar to the conventional one. Since only the members 48A and 48B are provided, the configuration is simplified. Therefore, the assembly workability can be improved and the cost can be reduced.

  Next, an operation for opening and closing the louvers 27A and 27B via the opening and closing mechanism in accordance with the operation of the operation members 48A and 48B will be specifically described.

  First, in the neutral position of the operation members 48A and 48B shown in FIG. 2, the louvers 27A and 27B are in a half-open state between the fully closed state and the fully open state. In this state, as shown in FIG. 7, when the operation members 48A and 48B are moved to the left in the horizontal direction, the louvers 27A and 27B are all overlapped by the louvers 27A and 27B adjacent to the upper and lower ends. Closed. Specifically, first, when the operation members 48A and 48B are moved to the left side, the link members 37A and 37B are moved upward in the vertical direction in the intermediate collars 13A and 13B according to the inclination of the guide groove 52. Then, as shown in FIG. 4A, in conjunction with the movement of the link members 37A, 37B, the pair of connecting members 34A, 34A and 34B, 34B located in the intermediate collars 13A, 13B are respectively integrally upward. Moved to. As a result, the pin coupling portions 32 of the fixed pieces 28A and 28B are moved upward following the connection members 34A and 34B. As a result, the base 30 of the fixing pieces 28A and 28B inserted through the non-movable vertical frame member 19 rotates around the attachment hole 29, and all the louvers 27A attached to the fixing part 31 coaxial with the base 30 are provided. 27B rotates integrally and enters a closed state. In addition, in the vertical rods 11A and 11B at both ends, the fixing pieces 28A and 28B are rotated and the connecting members 34A and 34B are moved upward in accordance with the rotation of the louvers 27A and 27B.

  On the other hand, as shown in FIG. 8, when the operation members 48A and 48B are moved to the right in the lateral direction, the louvers 27A and 27B are in a fully opened state rotated substantially horizontally. Specifically, first, when the operation members 48A and 48B are moved to the right side, the link members 37A and 37B are moved downward in the vertical direction in the intermediate collars 13A and 13B according to the inclination of the guide groove 52. Then, as shown in FIG. 4 (B), in conjunction with the movement of the link members 37A and 37B, the pair of connecting members 34A and 34A and 34B and 34B located in the intermediate collars 13A and 13B are respectively integrally downward. Moved to. As a result, the pin coupling portions 32 of the fixing pieces 28A and 28B are moved downward following the connection members 34A and 34B. As a result, the base 30 of the fixing pieces 28A and 28B inserted through the non-movable vertical frame member 19 rotates around the attachment hole 29, and all the louvers 27A attached to the fixing part 31 coaxial with the base 30 are provided. 27B rotates integrally and becomes an open state. Further, in the vertical rods 11A and 11B at both ends, the fixing pieces 28A and 28B are rotated and the connecting members 34A and 34B are moved downward in accordance with the rotation of the louvers 27A and 27B.

  Thus, in the shutter 10 of the present invention, the lateral operation of the operation members 48A and 48B is converted into the vertical movement of the link members 37A and 37B by the guide groove 52, and the movement of the link members 37A and 37B is converted. The connecting members 34A and 34B, which are moving in the same direction, are moved forward and backward in conjunction with each other, and the louvers 27A and 27B are rotated through the fixed pieces 28A and 28B. That is, since the conversion between the linear movement in which a large resistance or friction force is generated and the movement in the rotational direction is only the opening / closing portion of the louvers 27A, 27B, the opening / closing operation of the louvers 27A, 27B by the operation of the operating members 48A, 48B. Can be reduced.

  Here, in order to open and close the louvers 27A and 27B, the work amount of moving the link members 37A and 37B in the vertical direction is the case where the operation members are arranged to be movable in the vertical direction and are directly moved in the vertical direction. This is the same as the case where the operation members 48A and 48B are movable in the horizontal direction and are indirectly moved in the vertical direction through the guide groove 52 as described above. However, when the guide groove 52 that extends in the horizontal direction and inclines in the vertical direction is applied as in this embodiment, the operation amount (distance) increases, but the required operation force can be reduced. In other words, by changing the horizontal length of the guide groove 52, the vertical inclination angle can be changed, and the force required for the opening / closing operation can be easily reduced. In addition, when the lateral dimension of the guide groove 52 is increased, the rotation angle of the louvers 27A and 27B associated with the operation amount is reduced, so that the rotation angle of the louvers 27A and 27B can be easily finely adjusted.

  Further, when the operation member is arranged to be movable in the vertical direction, when the louvers 27A and 27B are directly rotated from the outside, the link members 37A and 37B can be easily opened and closed in conjunction with each other. However, in this embodiment, when the louvers 27A and 27B are to be directly rotated, the engaging projections 38 of the link members 37A and 37B abut against the inner wall of the guide groove 52, so that the link members 37A and 37B are It cannot be moved. Therefore, the problem concerning crime prevention can be solved sufficiently.

  Furthermore, the shutter 10 of the present embodiment is configured to have three rows of vertically long members of the vertical rod 11A, the intermediate rod 13A, 13B, and the vertical rod 11B, and is located in the vicinity of the intermediate rod 13A, 13B in the middle portion thereof. In addition, the operation members 48A and 48B are disposed, and the link members 37A and 37B are disposed so as to be positioned in the intermediate collars 13A and 13B. As a result, since the link members 37A and 37B can be constituted by linearly extending rod-like members, the operation force of the operation members 48A and 48B can be used as the opening / closing operation force of the louvers 27A and 27B without waste.

  The operation member 48A that opens and closes the louvers 27A and 27A located on the upper side with the middle rail 14 as a boundary, and the operation member 48B that opens and closes the louvers 27B and 27B located on the lower side are opened and closed. Since the operation directions are the same, it is possible to prevent the user from being confused when opening and closing the upper and lower louvers 27A and 27B, and convenience can be improved.

  Moreover, the first and second operation members 48A and 48B are provided at positions adjacent to each other in the vertical direction, and at the same rotation angle of the louvers 27A and 27B, the movement distances in the horizontal direction coincide with each other. The convenience at the time of adjusting the rotation angle of louvers 27A and 27B can be improved. That is, when the rotation angles of the louvers 27A and 27B are finely adjusted, the operation members 48A and 48B are generally operated while staring at the louvers 27A and 27B located at the line of sight. However, in the vertically long shutter 10 in which the louvers 27A and 27B are disposed above and below the middle rail 14 as a boundary, for example, it is necessary to operate the operation member 48B in a bent state in order to stare at the lower louver 27B. . However, in this embodiment, the upper and lower louvers 27A and 27B can be set to the same rotation angle by operating the operation members 48A and 48B to positions that coincide with the horizontal direction. For this reason, the user does not have to perform an unreasonable posture when adjusting the rotation angle of the louvers 27A and 27B located in a portion away from the line of sight, so that convenience can be improved.

  In addition, the movable louver type shutter of the present invention is not limited to the configuration of the above embodiment, and various modifications are possible.

  For example, as shown in FIG. 9, due to the installation location of the shutter 10, the length in the vertical direction is shorter than that of the above embodiment, and in the configuration in which the middle rail 14 is not provided, only one operation member 48 is provided. Good. In addition, as shown in FIG. 10, due to the installation location of the shutter 10, the operation members 48 </ b> A and 48 </ b> B are arranged in a configuration in which the lateral length is shorter than that of the above embodiment and the intermediate rods 13 </ b> A and 13 </ b> B are not provided. It arrange | positions so that it may be located in the vicinity of one vertical rod 11B. In this case, as shown in FIG. 11, the link members 37A and 37B are preferably provided with a bent portion 55 so that the ends thereof extend in the vertical direction in the vertical rod 11B.

  In the above embodiment, the link members 37A and 37B are composed of the rod-shaped main body and the separate locking member 41, but they may be integrally formed. Of course, the locking structure between the locking portion 39 and the connecting members 34A and 34B is not limited to the hole 36 and the rod 43, and can be changed as desired.

  Furthermore, in the above-described embodiment, the link members 37A and 37B, the base frame 44, and the operation members 48A and 48B are formed of resin, but may be formed of metal, and the molding material can be changed as desired. is there.
