Description

  The present invention relates to a blind in which a large number of slats are rotatably supported so that adjacent slats overlap each other when fully closed to improve shielding, and more particularly to a blind suitable for a plurality of units.

  Conventionally, the blind described in Patent Document 1 is known as a blind with improved shielding.

  The blind shown here supports a large number of slat holders, each supporting a number of slats, so that each frame can be pivoted, and each slat holder is connected by a link mechanism to rotate each slat in the same phase. When fully opened, the slats are rotated so that they are positioned in parallel. When fully closed, the slats are rotated so as to be connected in a flat plate shape so as to be shielded from light. Each slat is formed in a flat plate shape except for the end in the width direction, and the rotation axis of each slat is offset from the center line in the width direction of the slat to one side, and each flat plate portion of each slat is fully closed. Are arranged on substantially the same plane, and a curved portion is provided at the width direction end of the slat on the rotation axis side, and the other width direction end opposite to the curved portion of each slat is upward. A light shielding frame is provided in the vicinity of the longitudinal end of each slat to be in contact with the lower end of the turning locus of the curved portion and in contact with each flat plate portion of each slat when fully closed.

  When the slat is closed, the curved portion of each slat moves on the rotation trajectory which is a circle in contact with the upper surface of the light shielding frame, so that each slat is rotated horizontally without colliding with the light shielding frame. Both ends in the longitudinal direction are in contact with the upper surface of the light shielding frame, and the contact portion of each slat is in contact with the curved portion of the adjacent slat from above.

  By the way, depending on the size of the opening for setting the blind, there may be a case where a plurality of blinds are arranged in series instead of one blind. When multiple blinds are connected in this way, as shown in FIG. 6A, when all the blinds are operated at the same time, they can operate as if they were one blind. it can.

  However, as shown in FIG. 6B, when only some of the blinds are operated, or when some of the blinds cannot be operated due to a failure, the slat holder for holding the slats of the operated blinds There is a risk of interference with a blind link mechanism or the like that is not operating. As a result, when one blind hits the other blind, the rotation of the slat is constrained, and the slat is opened only halfway. In the worst case, there is a problem that the blind is damaged by interference. .

  As a means of avoiding such interference, the positions of the support driving parts of each blind (such as a link mechanism that rotationally drives the slats and a support bar that rotatably supports the slat holder) are shifted from each other in the longitudinal direction of the slats. Although it is conceivable, it is necessary to shift each blind individually, which takes time. In addition, when the slat is opened, the support drive unit can be seen by a person in the room. However, if the support drive unit of each blind is shifted, there is a problem that a problem occurs in design.

  The present invention has been made in view of such a problem, and provides a blind that can be independently manufactured and can be easily manufactured without disturbing the rotation of the slat when the blinds are continuously mounted. The purpose is to do.

In order to achieve the above-described object, according to the first aspect of the present invention, a number of slat holders are rotatably connected to the support drive units, and each slat holder holds a slat, and the slats are driven by the drive of the support drive unit. In the blind in which the holder rotates to open and close the slats, and when fully closed, the main body of all slats forms a closed surface and the ends overlap with each other adjacent slats.
The connection position of the slat holder at the end of the slat group holding the slat and the support drive unit is shifted in the longitudinal direction of the slats from the connection position of the other slat holder and the support drive unit, As a result, when the blinds are connected and the slats of the respective blinds open and close independently, the slat holders at the end portions do not interfere with the supporting drive parts of the adjacent blinds or the slat holders connected to the support drive parts. Or the support drive part to which the slat holder of this edge part is connected is arranged.

  According to a second aspect of the present invention, in the first aspect of the present invention, a crank-shaped offset arm portion whose tip is offset in the longitudinal direction of the slat is provided at the end portion of the support driving portion. The slat holder at the end is rotatably connected to the tip.

  According to a third aspect of the present invention, in the second aspect of the present invention, the offset arm portion is substantially L-shaped, and extends in the connecting direction from an offset piece extending in the longitudinal direction of the slat and an end portion of the offset piece. The slat holder holding piece is rotatably connected to the end portion of the slat holder.

  According to the present invention, in order to shift the connecting position of the end slat holders in the longitudinal direction of the slats relative to the connecting positions of the other slat holders, the blind slats can be opened and closed independently when the blinds are connected. Even if it does, it will avoid that the support drive part to which the slat holder of an edge part or this slat holder is connected interferes with the support drive part of the adjacent blind, or the slat holder connected to this support drive part. be able to.

  It is only necessary to shift the connecting position where the end slat holder supporting the end slat is connected, and it is not necessary to configure the blinds in which the positions of the entire support driving unit are offset from each other. It can be unified, manufacturing becomes easy, and the design is not impaired when the slat is opened.

  In addition, since the connecting position between the end slat holder and the support drive unit is shifted by the offset arm portion formed at the tip of the support drive unit, the shape of the end slat holder connected to the offset arm unit is changed. It is not necessary to make it different from the shape of other slat holders, and the slat holder at the end can be made common with other slat holders.

FIG.

Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 5.
As shown in FIGS. 4 and 5, the blind 10 according to this embodiment can be so-called connected, for example, arranged on a skylight in parallel along the rotation direction of the slats. 4 and 5 show two blinds 10 connected in series, but the number of blinds connected in series is not limited to two, and may be any number.

  In each blind 10, as shown in FIG. 4, the support drive unit 12 is suspended from the structure by the support bolt B.

  The support drive unit 12 includes a frame 13 and a motor unit 14 including a motor, and a link mechanism 16 that is operated by driving the motor is coupled to the motor unit 14. The link mechanism 16 includes a first joint bar 17 whose one end is fixed to the output shaft of the motor, a second joint bar 18 whose one end is pivotally attached to the other end of the first joint bar 17, and a second joint bar 18. The swing rail 20 is pivotally attached to the other end of the swing rail 20. Except for a leading slat holder 22A, which will be described later, one end of a large number of slat holders 22 is pivotally attached to the swing rail 20 at a predetermined interval in the longitudinal direction of the swing rail 20. Further, the frame 13 is provided with a number of support bars 24 extending vertically downward corresponding to the slat holders 22, and each support bar 24 has the other end of the corresponding slat holder 22 at its center of rotation. At point C, it is pivotally attached.

  The slats 26 are respectively held by all the slat holders 22 so that a large number of slats 26 are supported in an aligned state. The rotation center point C of the slat holder 22 is offset to one end side with respect to the lateral direction center of the slat 26, and the slat 26 is centered on the rotation center point C with respect to the support drive unit 12. It is rotatably supported.

  As will be described later, the swing rail 20 can be moved back and forth by the link mechanism 16 in order to open and close the slat 26, and moves forward to open the slat 26. And the front-end | tip of the swing rail 20 is located back rather than the site | part with which the end of the slat holder 22A of a front-end should be connected originally. Instead, as shown in FIGS. 2 and 3, one end of an offset arm 32 bent in a crank shape is attached to the tip of the swing rail 20, and a leading slat holder is attached to the other end of the offset arm 32. 22A is rotatably connected.

  More specifically, one end of the offset arm 32 is introduced into the swing rail 20, and the main body of the offset arm 32 led out from the swing rail 20 has a substantially L shape and extends in the longitudinal direction of the slat 26. The offset piece 32a includes a slat holder holding piece 32b that extends in parallel with the axis of the swing rail 20 from the end of the offset piece 32a and connects the leading slat holder 22A.

  Further, as shown in FIGS. 2 and 3, an offset spacer 34 protruding in the longitudinal direction of the slat 26 is provided from the support bar 24 provided corresponding to the slat 26 at the tip, and an end portion of the offset spacer 34 is provided. The slat holder 22A is rotatably connected to the slat holder 22A.

  With the offset arm 32 and the offset spacer 34, the connecting position of the leading slat holder 22A supporting the leading slat 26 and the support driving unit 12 is more than the connecting position of the slat holder 22 other than the leading and the support driving unit 12. The leading slat holder 22 </ b> A is displaced in the longitudinal direction of the slat 26 and is disposed at a position offset in the longitudinal direction of the slat 26 with respect to the slat holders 22 other than the leading slat 26.

  Therefore, as shown in FIGS. 5 (a) and 5 (b), even when the blinds 10 are connected, the blinds 10 (hereinafter referred to as “rear blinds” disposed behind the two adjacent blinds). The leading slat holder 22A is connected to the support drive unit 12 in the longitudinal direction of the slat 26 from the axis of the swing rail 20 of the blind 10 (hereinafter referred to as “front blind”) disposed in the front. The slat holder 22A at the head of the rear blind 10 is moved at a position shifted in the longitudinal direction with respect to the swing rail 20 of the front blind 10 during the rotational movement.

  A shielding frame 30 (FIG. 4) is arranged around the lower side of the slat 26, and the shielding frame 30 is fixed to the structure.

Next, the operation of the present embodiment will be described.
When the motor of the motor unit 14 rotates and the first joint bar 17 of the link mechanism 16 rotates, the swing rail 20 and the offset arm 32 perform a translational swinging motion with the movement of the second joint bar 18, and each slat holder. 22 and each slat 26 rotate around the rotation center point C in the same phase, and the slats 26 are parallel to each other by this rotation to form a gap between adjacent slats 26. Displacement between the fully opened state (FIG. 3) and the fully closed state (FIG. 2) in which each slat 26 is on the same plane and forms a closed surface 28, and there is no gap between adjacent slats 26. can do. In order to prevent a gap from being formed between the adjacent slats 26 in the fully closed state, the end portions of the respective slats 26 are overlapped with the end portions of the adjacent slats 26.

  Here, also at the boundary portion of the blinds 10 that are connected, the end portion of the front slat 26 of the rear blind 10 overlaps the end portion of the rearmost slat 26 of the front blind 10.

  When the connected blinds 10 perform the same operation all at once, the swing rails 20 operate in parallel, so that no interference between adjacent blinds 10 occurs. For example, as shown in FIG. 4 (a), when the slats of all the blinds 10 to be connected are closed, the swing rails 20 of all the blinds 10 take the most moved position, A space is maintained between the rear end of the swing rail 20 of the front blind 10 and the slat holder 22A of the front slat 26 of the rear blind 10.

  On the other hand, as shown in FIG. 4B, when the slat 26 of the front blind 10 is kept closed and only the slat 26 of the rear blind 10 is opened, the swing rail 20 of the rear blind 10 is moved forward. The slat holder 22 moves around the rotation center point C until the slat 26 moves to a vertical angle. Thereby, as shown in FIGS. 4B and 5B, the leading slat holder 22A is tilted forward from the rear end of the swing rail 20 of the front blind 10, but as described above, Since the position of the rail 20 is offset in the longitudinal direction of the slat 26, the swing rail 20 of the front blind 10 and the front slat holder 22A of the rear blind 10 can be prevented from interfering with each other.

  In this way, since interference between adjacent blinds can be prevented, only the slats 26 of the rear blind 10 can be fully opened. That is, only the slat 26 of one blind 10 can be rotated, and the independent operation of the blinds 10 to be connected can be enabled. Further, even when the other blind 10 cannot be rotated due to a failure, the one blind 10 can be opened and closed.

  Since it can be realized only by providing the offset arm 32 and the offset spacer 34, it can be applied to all the blinds 10, and the structure of each blind 10 can be unified, so that the manufacturing is easy. By providing the offset arm 32 and the offset spacer 34, the shape of the leading slat holder 22A does not need to be different from the shape of the other slat holders 22, and parts can be shared.

  Further, when the blinds are viewed from the room side with the slats 26 fully open, the support drive unit 12 including the swing rails 20 is aligned, so that the design is not impaired.

  In the above example, only the connecting position between the leading slat holder 22A that moves forward when the slat 26 rotates and the support drive unit 12 is shifted in the longitudinal direction of the slat 26, but this is not limitative. Instead, only the connecting position between the last slat holder 22 </ b> A and the support drive unit 12 may be shifted in the longitudinal direction of the slat 26.

  In the above example, the slat holder 22A at the end of the first or last part is shifted with respect to the other slat holders 22, thereby supporting the slat holder 22A at the end of one blind and the other adjacent blind. Although interference with the drive unit 12 has been prevented, the present invention is not limited to this. By shifting the slat holder 22A at the end with respect to the other slat holders 22, Further, interference with the slat holder 22 of the other adjacent blind may be prevented, or the support drive unit 12 to which the slat holder 22A at the end of one blind is connected, and the slat holder of the other adjacent blind Interference with 22 or the support drive unit 12 to which it is connected may be prevented.
