Description

  The present invention relates to a vertical blind.

  Conventionally, a vertical blind in which a louver is suspended from each of a plurality of carriers movable in a head rail is known. Each louver is provided on each of the plurality of carriers and is suspended by a suspension shaft having a hook formed at the end. The vertical blind is a folded state in which a plurality of carriers move in the longitudinal direction so that the louver group is brought close to one end of the head rail, or the louver group is arranged substantially evenly from one end to the other end of the head rail. It becomes a state. Further, when the suspension shaft rotates, each louver rotates, so that the louver group is in a fully closed state in which it is substantially parallel to the longitudinal direction of the head rail or in a fully open state in which it is substantially vertical. Further, the movement of the plurality of carriers and the rotation of the suspension shaft are performed by the rotation of the movement shaft and the rotation shaft extending in the longitudinal direction of the head rail, respectively.

  In addition, when the vertical blind is in a convoluted state, all the carriers are close to one end side of the head rail, so that the moving shaft and the rotating shaft are supported only at both ends. The center part is subjected to its own weight and is bent. In order to prevent such bending of the moving shaft and the rotating shaft, a rod support member provided so as to be movable in the longitudinal direction and to be able to be locked to the head rail in the vertical direction is used.

  As a technology related to the support member in such a vertical blind, a first rod support member adjacent to the master runner, a second rod support member adjacent to the first rod support member, and adjacent to the second rod support member A third rod support member is sequentially disposed on the head rail, a permanent magnet attracted to the permanent magnet of the master runner is attached to the first rod support member, and the first rod support is attached to the second rod support member. An iron piece magnetically attracted to the permanent magnet of the member is attached, and the third rod support member projects toward the master runner and passes through a through hole provided in the second rod support member. A vertical type characterized in that an iron bar that is magnetically attracted to a magnet is attached, and a stopper that stops each of these rod support members at a predetermined position is provided in the head rail. Rind, is known (see Patent Document 1).

Japanese Utility Model Publication No. 62-177898

  According to the above-described vertical blind, since the rod support members are stopped at positions spaced apart from each other in a state where the louver is folded, it is possible to prevent the movement shaft and the rotation shaft from being bent. However, since each rod support member is located between one end of the head rail and the master carrier in a state where the louver is deployed, the head rail end portion and the master carrier are dependent on the thickness of each rod support member in the longitudinal direction of the head rail. As a result, there is a problem that even if the louver group is closed, a portion that is not covered by the louver is generated at one end of the vertical blind and light leakage occurs. The distance between the head rail end and the master carrier depends on the number of rod support members. This problem becomes particularly noticeable as the size of the vertical blind increases, because more rod support members are required to prevent deflection due to its own weight.

  Therefore, the present invention has been made in view of such problems, and an object thereof is to provide a vertical blind that reduces light leakage caused by a rod support member.

  In order to solve the above-described problem, the vertical blind according to the present embodiment is pulled in one direction or pushed in the reverse direction by a master carrier arranged in the head rail so as to be movable in the longitudinal direction of the head rail. A vertical blind that suspends and supports a louver from each of the carriers, and is supported in a pivotal manner in the head rail so as to extend in the longitudinal direction, and is rotated by the master carrier or moved in the longitudinal direction. At least one drive shaft that transmits drive force, and a rod that is provided in the head rail so as to be movable in the longitudinal direction so as to be adjacent to the one direction side with respect to the master carrier, and supports at least the drive shaft The master carrier has an axial direction that is vertical and a louver is suspended from the lower end. A shaft that hooks are formed, in a state adjacent to the rod support member, an upper end of said shaft and having an offset axis which is provided so as to be positioned below the rod support member.

  According to the present invention, light leakage caused by the rod support member can be reduced.

<First Embodiment>
(Overall configuration of vertical blind)
First, the overall configuration of the vertical blind according to the present embodiment will be described with reference to FIGS. 1 and 2. FIG. 1 is an overall front view showing a state in which a louver of a vertical blind according to the present embodiment is developed. FIG. 2 is an overall front view showing a state in which the louver of the vertical blind shown in FIG. 1 is closed. In the following description, when the longitudinal blind is viewed from the side and the installed vertical blind is viewed from the side, the installation surface side (for example, the opening window side) is the rear side, and vice versa (for example, the indoor side). ) Is assumed to be the front side. In the longitudinal direction, the side where the master carrier is located when the vertical blind is in the unfolded state will be described as the unfolded side, and the opposite will be described as the convolution side.

  As shown in FIGS. 1 and 2, the vertical blind 1 includes a head rail 11 fixed to a fixing part such as a window frame or a wall surface by a bracket (not shown). In the head rail 11, a moving shaft 12 and a rotating shaft 13 which are driving shafts extending in the longitudinal direction of the head rail 11 are rotatably supported at different positions in the front-rear direction, and one master carrier 15, Carrier 16 and a plurality of rod support members 17 are provided. In addition, a spacer link 18 that connects the master carrier 15 and the carrier 16 or the carriers 16 to each other is provided in the head rail 11, a moving operation unit 22 is connected to one end of the moving shaft 12, and one end of the rotating shaft 13. The rotation operation unit 23 is connected to the. The movement operation unit 22 and the rotation operation unit 23 can have arbitrary configurations. In the present embodiment, each of the movement operation unit 22 and the rotation operation unit 23 includes a pulley fixed to one end of the shaft and an operation cord spanned on the pulley. Composed. By operating the operation codes of the movement operation unit 22 and the rotation operation unit 23 to rotate the pulley, the shaft connected to the pulley is rotationally driven.

  The master carrier 15, the plurality of carriers 16, and the plurality of rod support members 17 are provided so as to be movable in the longitudinal direction within the head rail 11, and these are arranged from the deployment side with the plurality of rod support members 17 and the master carrier 15. The plurality of carriers 16 are arranged in this order. Among them, only the master carrier 15 moves in the longitudinal direction by the rotation of the moving shaft 12, and the plurality of carriers 16 are pulled in one direction by the master carrier 15 via the spacer links 18 and move to the deployment side. It is pushed in the direction opposite to the pulling direction and moves to the folding side. The plurality of rod support members 17 are provided to be locked to the head rail 11 in the vertical direction, and are pulled by the master carrier 15 attracted by magnetism to move to the convolution side and are pushed by the master carrier 15. And move to the deployment side. In addition, the some rod support member 17 is comprised so that each rod support member 17 may be latched in a mutually different position in a longitudinal direction in the movement to the convolution side. Further, the rotational force by the moving shaft 12 and the rotating shaft 13 is not transmitted to the plurality of rod support members 17.

  A louver 21 as a shielding material is suspended from each of the master carrier 15 and the plurality of carriers 16. An offset louver 21 a that is offset from the louver 21 by a predetermined distance from the louver 21 is suspended from the master carrier 15. The offset louver 21a has the same configuration as the louver 21 and has a different arrangement position. Each louver 21 is transmitted through the corresponding master carrier 15 or carrier 16 so that the rotation of the rotary shaft 13 is transmitted, and as shown in FIG. As shown, it is rotated so as to be in a fully closed state that is substantially horizontal. The offset louver 21a rotates in conjunction with the louver 21 corresponding to the master carrier 15, and its operation will be described in detail later.

(Career structure)
Next, the configuration of the master carrier and the carrier will be described. FIG. 3 is a side sectional view showing the configuration of the master carrier. FIG. 4 is an exploded perspective view showing the configuration of the master carrier. FIG. 5 is a perspective view showing the configuration of the master carrier and the carrier.

  As shown in FIGS. 3 and 4, the master carrier 15 includes a carrier case 150, a suspension shaft 151, a worm 152, a worm wheel 153, a friction spring 154, a lead nut 155, an offset shaft 156, and a connecting member 157. The carrier case 150 is a housing in which a part of the suspension shaft 151, a worm 152, a worm wheel 153, a friction spring 154, and a lead nut 155 are built in an internal space thereof, and the penetrating through the moving shaft 12 and the rotating shaft 13. A hole is formed.

  The suspension shaft 151 is a member whose axial direction is vertical, and has a hook 151a for hanging the louver 21 at one end protruding downward from the carrier case 150, and the other end existing inside the carrier case 150 is a worm. Connected to the wheel 153. Here, the vertical direction indicates a direction orthogonal to the longitudinal direction and the front-rear direction of the head rail 11. The worm 152 is a member that has an inner peripheral surface and an outer peripheral surface that transmits a rotational force to the worm wheel 153, with the axial direction facing the longitudinal direction. The inner peripheral surface of the worm 152 meshes with each of a plurality of grooves extending in the longitudinal direction formed on the peripheral surface of the rotary shaft 13 so as to be movable in the rotational direction and slidable in the longitudinal direction. The outer peripheral surface meshes with the worm wheel 153. The worm wheel 153 is arranged so that the rotation axis thereof is oriented in the vertical direction at the center portion of the head rail 11 in the front-rear direction, is coaxial with the suspension shaft 151, and the lower portion overlaps the upper portion of the suspension shaft 151. A rotational force is transmitted to the suspension shaft 151. The friction spring 154 is interposed between the worm wheel 153 and the suspension shaft 151 at a position where the worm wheel 153 and the suspension shaft 151 partially overlap in the vertical direction, and applies a friction force to both.

  The rotational force of the rotary shaft 13 is transmitted to the suspension shaft 151 via the worm 152, the worm wheel 153, and the friction spring 154 so that the louver 21 suspended from the suspension shaft 151 rotates. Further, in a situation where a load is applied to the louver 21 and the louver 21 cannot rotate, the worm wheel 153 can idle with respect to the suspension shaft 151 by the friction spring 154, so that the louver 21 or worm 152, worm wheel 153 and suspension are suspended. Breakage of the lowering shaft 151 can be prevented.

  The lead nut 155 is a member that is provided with a through hole and is fixed to the carrier case 150 so that the penetrating direction thereof is in the longitudinal direction. A female screw that engages with the male screw of the moving shaft 12 on the inner peripheral surface. Is formed. According to the lead nut 155, when the moving shaft 12 is rotated, the master carrier 15 moves in the longitudinal direction along the moving shaft 12.

  The offset shaft 156 is a member in which the axial direction faces the vertical direction in the same manner as the suspension shaft 151, and has a hook 156 a for hanging the louver 21 a at the lower end, and in the longitudinal direction with respect to the suspension shaft 151. It is arranged at a position away from the deployment side by a predetermined distance. The louver 21 a is the same as the louver 21, but is referred to as an offset louver in the following description in order to distinguish it from the louver 21. The connecting member 157 has a bridge extending in the longitudinal direction and two connecting portions provided at both ends thereof, one connecting portion is detachably connected to the hanging shaft 151, and the other connecting portion is an offset shaft 156. Is detachably connected. Note that the distance in the longitudinal direction of the offset shaft 156 relative to the suspension shaft 151 depends on the length of the bridge of the connecting member 157, and the length of this bridge depends on the thickness of the rod support member 17 in the longitudinal direction and the head rail 11. This is based on the total number of rod support members 17 provided, the width of the louvers 21, and the like. The connecting member 157 is connected to the suspension shaft 151 and the offset shaft 156 so as to be positioned below the lower end of the rod support member 17 in the vertical direction, and more specifically, the upper end of the connected offset shaft 156. Is connected to be positioned below the lower end of the rod support member 17.

  As shown in FIG. 5, the carrier 16 includes a carrier case 160, a suspension shaft 161, a worm 162, a worm wheel (not shown), and a friction spring. The operations of the suspension shaft 161, the worm 162, the worm wheel, and the friction spring are the same as those of the master carrier 15. Unlike the master carrier 15, the carrier 16 does not include a lead nut 155, and the moving shaft 12 is inserted into a through hole provided in the carrier case 160. Accordingly, the rotational force of the moving shaft 12 is not transmitted to the carrier 16, and the carrier 16 can simply move in the longitudinal direction relative to the moving shaft 12.

  A fixing groove for fixing the spacer link 18 to be slidable in the longitudinal direction is formed in the upper part of the carrier case 150 of the master carrier 15 and the upper part of the carrier case 160 of the carrier 16. The fixing groove is formed with claws that can slide the spacer link 18 in the longitudinal direction and restrict the movement in the vertical direction at different positions in the front-rear direction. The spacer link 18 connects the carriers 16 arranged adjacent to each other, or the master carrier 15 and the carrier 16 adjacent thereto. One of the fixed ends 18 a of the spacer link 18 is fixed to the fixing groove of the carrier 16 on the folding side, and the other free end 18 b of the adjacent spacer link 18 is fixed to the fixing groove of the master carrier 15 or the carrier 16. It is slidably fitted so as to overlap the upper side of the fixed end 18a. According to such a spacer link 18, the separation distance between adjacent carriers can be changed with the length of the spacer link 18 being the maximum distance.

(Operation of rod support member)
Next, the operation of the rod support member will be described. FIG. 6 is a front view in the head rail showing stepwise the state of the rod support member moved in the end direction by the master carrier. FIG. 7 is a plan view in the head rail showing the state of the rod support member moved in the end direction by the master carrier. 6A shows a state where the master carrier moves to the deployment side, FIG. 6B shows a state where the master carrier abuts on the rod support member, and FIG. 6C shows a state where the master carrier contacts the rod support member. FIG. 7 shows the same state as FIG. 6A.

  As shown in FIG. 6 (a), among the plurality of rod support members 17, the rod support member 17a provided on the most folding side in the longitudinal direction is provided on the stopper pin 111 when the vertical blind 1 is in the folded state. By being locked, the head rail 11 is placed at a predetermined locking position in the longitudinal direction. As shown in FIG. 7, the stopper pin 111 is formed on the head rail 11 and protrudes in the front-rear direction so as to lock the rod support member 17 a to the folding side so as not to move. Since the rotational force of the moving shaft 12 is not transmitted to the rod support member 17a, even if the master carrier 15 is moving to the deployment side, the deployment side end of the master carrier 15 is folded from the position of the stopper pin 111. As long as it is located on the side, the rod support member 17a is not moved from the locking position.

  As shown in FIG. 6 (b), when the master carrier 15 is moved and its development side end abuts against the rod support member 17a and further moves to the development side, the rod support is shown in FIG. 6 (c). The member 17a is pushed by the master carrier 15 and moves from the locking position to the deployment side. The rod support member 17b disposed adjacent to the deployment side of the rod support member 17a is indirectly pushed by the master carrier 15 via the rod support member 17a, and the rod adjacent to the deployment side with respect to the rod support member 17b. The support member 17c is also pushed in the same manner.

(Operation of offset louver)
Next, the operation of the offset louver will be described. FIG. 8 is a front view in the headrail showing stepwise the state of the vertical blind in which the louver group is closed after the blind is in the unfolded state. FIG. 9 is a plan view in the head rail showing the vertical blind in the unfolded state and in the fully open state. FIG. 10 is a plan view showing a state of the louver group when the offset louver is changed from the fully open state to the fully closed state. In FIG. 8, (a) shows a state where a plurality of rod support members are moved to the deployment side end, (b) shows a state where the rod support member has moved to the deployment side end, (c) Indicates a state where the louver is fully closed by rotating. In FIG. 10, (a) shows a state corresponding to FIG. 8 (b), (d) shows a state corresponding to FIG. 8 (c), and (b) and (c) are shown in (a). The process from the state shown to the state shown in (d) is shown.

  As shown in FIG. 8A, when the rod support members 17a to 17c are pushed directly or indirectly to the deployment side by the master carrier 15, as shown in FIG. 8B, the rod support members 17c. Comes into contact with the side end of the head rail 11, and the vertical blind 1 is in a developed state. Specifically, as shown in FIG. 9, the movement shaft 12 and the regulating portion 12 a provided at the deployment side end of the rotary shaft 13 abut against the regulation portion 13 a, and further movement toward the deployment side is regulated. The In such an unfolded state, when the rotation operation unit 22 is operated, the rotational force of the rotation shaft 13 is transmitted to the master carrier 15 and the plurality of carriers 16 to rotate the louver group, as shown in FIG. Fully closed state. At this time, the offset louver 21 a rotates in conjunction with the rotation of the louver 21 corresponding to the master carrier 15. The rotation of the offset louver 21a will be described below.

  When the rotating shaft 13 is rotated in the fully opened state as shown in FIG. 10A, the louver group is rotated as shown in FIG. 10B, and the louver rotated by the hanging shaft 151 in the louver group. 21 contacts the offset louver 21a. When the louver 21 is further rotated, the offset louver 21a is pushed by the louver 21 and rotates as shown in FIG. Here, the offset louver 21a is pushed in one of two divided areas divided by the axis of the offset shaft 156 in the width direction as a pushing area. When the louver 21 is rotated until the louver 21 is fully closed, the offset louver 21a is also fully closed as shown in FIG. Since the offset louver 21a is rotated until the fully closed state, the louver 21 rotated by the suspension shaft 151 has an end portion on the offset louver 21a side in the width direction when the fully closed state is reached. It is desirable that the offset louver 21a is located in the pushing region.

  Thus, in the operation from the fully open state to the fully closed state, the offset louver 21a is rotated by the louver 21 rotated by the suspension shaft 151. On the other hand, with respect to the operation from the fully closed state to the fully open state, as shown in FIG. 10A, the louver group is in a state substantially orthogonal to the longitudinal direction of the head rail 11 in the fully open state. Can be pushed by the louver 21 until it becomes a halfway state from the fully closed state to the fully open state, but is not pushed until it is completely opened from this halfway state. Therefore, it is conceivable to provide a mechanism for urging the offset shaft 156 with the rotational force in the rotational direction leading to the fully open state. An example of such a mechanism is a rotation transmission mechanism disclosed in Japanese Patent Application Laid-Open No. 2010-150857.

  As described above, according to the vertical blind according to the first embodiment, the offset louver that is suspended on the offset shaft by providing the offset shaft that is offset from the suspension shaft of the master carrier by a predetermined distance toward the deployment side. Can cover the gap due to the thickness of the rod support member, and reduce light leakage. In addition, by connecting the suspension shaft and the offset shaft with a connecting member, the configuration of the master carrier is changed according to the thickness and number of rod support members necessary to prevent the moving shaft and the rotating shaft from being bent. Without any problem, it is possible to cope with the gap by using connecting members having different bridge lengths. In addition, since the connecting member can be attached to and detached from the suspension shaft and the offset shaft, the offset shaft can be attached to and detached from the master carrier.Therefore, depending on the installation situation of the vertical blind at the installation site, An offset louver can be attached after installation of the vertical blind to reduce light leakage.

<Second Embodiment>
Next, a vertical blind according to the second embodiment will be described. Since the vertical blind according to this embodiment is different from the first embodiment in the configuration of the master carrier, only the configuration of the master carrier will be described below. FIG. 11 is a front view showing the configuration of the master carrier of the vertical blind according to the second embodiment. FIG. 12 is a front sectional view showing the configuration of the master carrier shown in FIG.

  As shown in FIGS. 11 and 12, the master carrier 15a according to this embodiment is provided with a transmission mechanism that transmits the rotational force transmitted to the suspension shaft 151 to the offset shaft 156 as well in the first embodiment. Different from the master carrier 15. Similarly to the master carrier 15, the carrier case 150 a of the master carrier 15 a incorporates a part of the suspension shaft 151, a worm 152, a worm wheel 153, a friction spring 154, and a lead nut 155, and an offset shaft 156. And a transmission mechanism are built-in. Here, as in the first embodiment, the offset shaft 156 is separated from the suspension shaft 151 by a predetermined distance on the deployment side in the longitudinal direction, and its upper end is positioned below the lower end of the rod support member 17. Placed in. The transmission mechanism includes a rotation gear 158a provided on the suspension shaft 151 to rotate integrally, a transmission gear 158b that meshes with the rotation gear 158a and transmits a rotational force to the offset shaft 156, and an offset shaft 156 to rotate integrally. The offset gear 158c is provided and meshes with the transmission gear 158b. Here, the transmission gear 158b is a spur gear that is disposed between the suspension shaft 157 and the offset shaft 156, and is rotatably fixed inside the carrier case 150a so that the rotation shaft faces the vertical direction.

  Thus, by providing a transmission mechanism that transmits the rotational force of the suspension shaft to the offset shaft in the master carrier, the offset louver can be rotated without causing the louver to contact the offset louver. And the rotation angle of the offset louver can be synchronized to improve the design of the opening / closing operation.

<Third Embodiment>
Next, a vertical blind according to the third embodiment will be described. Since the vertical blind according to the present embodiment is different in the configuration of the master carrier and the spacer link, only these configurations will be described below. FIG. 13 is a front view showing the configuration of the master carrier of the vertical blind according to the third embodiment. FIG. 14 is a front sectional view showing the configuration of the master carrier shown in FIG. FIG. 15 is a front view in the head rail showing the distance between the master carrier and the carrier and the distance between the carriers.

  As shown in FIG. 13 and FIG. 14, the master carrier 15 b according to the present embodiment is a member in which the axial direction faces the vertical direction instead of including the suspension shaft 151, and the upper end is connected to the worm wheel 153. The rotary gear 158 is provided so as to rotate integrally with the vertical rotary shaft 151b. The vertical rotation shaft 151b differs from the suspension shaft 151 only in that it does not have a hook 151a, and its operation is the same as that of the suspension shaft 151. Therefore, the transmission composed of the rotation gear 158a, the transmission gear 158b, and the offset gear 158c. The operation of the mechanism is the same as in the second embodiment.

  Further, because the suspension shaft 151 is not provided, the separation distance between the master carrier 15b in the deployed state and the carrier 16 adjacent thereto is different from those in the first and second embodiments. Therefore, in this embodiment, the spacer link 28 shorter than the spacer link 18 that connects the carriers 16 is used as a member that connects the master carrier 15b and the carrier 16 adjacent thereto. This spacer link 28 differs from the spacer link 18 only in length, and the other configuration is the same as that of the spacer link 18. The length of the spacer link 28 is the same as the distance between the suspending shafts 161 of the adjacent carriers 16 in the unfolded state in which the distance between the offset shaft 156 of the master carrier 15b and the suspending shaft 161 of the adjacent carrier 16 is the same. It is desirable to do. In this case, the spacer link 28 is configured to be shorter than the spacer link 18 by the distance between the vertical rotation shaft 151b and the offset shaft 156 in the longitudinal direction.

  In this way, by providing only the offset shaft on the master carrier and shortening the distance between the master carrier in the deployed state and the carrier adjacent thereto, the distance between the offset shaft and the suspension shaft can be reduced between the suspension shafts. This can be the same as the separation distance, and by extension, light leakage can be reduced while maintaining the design.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. For example, a moving shaft was used as a means for moving the master carrier in the longitudinal direction of the head rail, but a part of a cord arranged in a loop in the head rail was connected to the master carrier, and from the end of the head rail The master carrier connected to the cord may be moved by operating the cord of the hanging portion. Further, the moving shaft and the rotating shaft may be connected to an electric motor, respectively, and these shafts may be driven to rotate electrically. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
