DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a blind type blind.

[0002]

2. Description of the Related Art A blind type has a self-supporting frame composed of a pair of vertical frames and a pair of horizontal frames, and a blind disposed in a space of the frame. As such a conventional blind type, for example, as shown in Japanese Utility Model Publication No. 2-28784 and Japanese Utility Model Publication No. 2-28785, there is a type in which a blind is a slat type and a slat is rotatable. . The vertical position of the slats completely obstructs the field of view, while the horizontal position of the slats allows the opposite sides of the slat to be seen from each other. As another type, there is a type in which the blinds can be folded up, the view is blocked when the blinds are lowered, and the blinds are folded up when looking at the other side.

[0003]

However, in the case where the slats are operated to rotate, when the slats are set in a horizontal state, the opposite sides can be seen on the entire surface of the slats, and the field of view is unnecessarily widened. There's a problem. That is, for example, when it is desired to have a conversation with a next-seat person who is separated by a vertical line, it is sufficient to see the upper part of the upper body from each other, but even the feet can be seen. In the case of the type in which the slats are folded up upward, the same problem as described above occurs.In addition, an operation of pulling the elevating operation code by a length substantially equal to the height of the blind is required, and the The work of pulling down the lifting operation cord or the knob attached to it from below to above is troublesome. An object of the present invention is to solve such a problem.

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by making it possible to lower the blind only by the upper half. That is, the blind type of the present invention includes a rectangular frame including a pair of vertical frames and a pair of horizontal frames, a blind disposed in a space of the frame, and a stopper mechanism provided in one vertical frame of the frame. The upper end of the blind is connected to the movable member of the stopper mechanism via the elevating operation cord, and when the movable member of the stopper mechanism is moved upward, the upper end side of the blind descends, and conversely, the movable member is moved. When the blind is moved downward, the upper end of the blind moves upward, and when the movable member of the stopper mechanism reaches the upper movable limit position, the blind is configured such that about half of the upper side is opened.

[0005]

With the movable member of the stopper substantially at the center of the vertical frame, the upper end of the blind is raised to a position in contact with the upper vertical frame, and the blind is completely closed.
In this state, when the movable member is moved to the upper movable limit position by operating the stopper mechanism, the upper half of the blind is opened. Therefore, it is possible to obtain a view of only a necessary portion. The operating distance of the movable member of the stopper mechanism is about half the height of the blind

[0006]

1 to 6 show an embodiment of the present invention. Frame 10 and pleated blind 14
And The frame 12 has vertical frames 16 and 18,
It has an upper horizontal frame 20 and a lower horizontal frame 22, which are formed in a rectangular shape. The vertical frames 16 and 18
And upper horizontal frame 20 are provided with corner covers 24 and 26, respectively.
Are linked by Legs 28 and 30 are provided at the lower ends of the vertical frames 16 and 18, so that the frame 12 can stand on its own. The blind 14
As shown in FIG. 3, a head rail 32 is provided at an upper portion, and a bottom rail 34 is provided at a lower portion. Further, the blind 14 has a width such that both ends are positioned inside the vertical frames 16 and 18. The blind 14 is supported by support cords 36 and 38 fixed to the frame 12. The lower ends of the support cords 36 and 38 are connected to the bottom rail 34 by sequentially passing through the blinds 14 having the folds. Both ends of a lifting operation cord 40 are respectively connected to both ends of a head rail 32 of the blind 14. That is, the elevating operation cord 40 connected to the left end side of the head rail 32 in FIG.
Extends upward to the guide roller 42 disposed inside the
As a result, it is bent by about 90 degrees and wound around the guide roller 44 in the other corner cover 26, then extends downward, is wound around a shaft portion of a movable member 48 of a stopper mechanism 46 described later, and then extends upward again. It is wound around a guide roller 44 and then extends downward and is connected to the right end side of the head rail 32 in FIG. As shown in FIG. 4, the stopper mechanism 46 includes a groove 50 provided vertically in the vertical frame 18 and a rack 5 provided
2 and a movable member 48 having meshing claws 54 that can mesh with the rack 52. The groove 50 is provided until reaching the upper end of the vertical frame 18, and is interrupted at the lower end of the corner cover 26. The movable member 48 is guided so as to be vertically movable along the groove 50. As shown in FIG. 5, the movable member 48 includes a sliding portion 56 movably supported in the groove 50, a meshing claw 54 rotatably supported on the sliding portion 56 via a support shaft 58, and a meshing claw 54.
And a knob 60 capable of moving the engagement pawl 54 between the engagement position and the release position.

Next, the operation of this embodiment will be described. FIG. 1 shows a state in which the blind 14 is closed to block the field of view. That is, the movable member 48 of the stopper mechanism 46 is pulled down to the vicinity of the middle portion of the vertical frame 18, and the stopper mechanism 46 is in a state where the engagement claws 54 are engaged with the rack 52 as shown in FIG. 5. Therefore, although an upward force is applied to the movable member 48 from the elevating operation cord 40, the movable member 48 does not move, and the blind 14 is held in the fully closed state. When the user wants to open the blind 14 from this state, the user operates the knob 60 and, as shown in FIG.
Is pivoted about the support shaft 58 to release the engagement of the engagement claw 54 with the rack 52. As a result, the movable member 48 becomes movable. Since the weight of the blind 14 is acting on the movable member 48 via the lifting / lowering operation cord 40, when the movable member 48 is moved upward by using this, the head rail 32 of the blind 14 starts to descend. . When the movable member 48 reaches the upper end (movable limit position) of the groove 50 provided in the vertical frame 18 as shown in FIG. 2, the movable member 48 cannot move any more, and the blind 14 As shown in FIG. 2, the operation is stopped in a state of being opened about halfway. As a result, the blind 14 is opened to the height of the line of sight, and only the upper body or face is visible from the other side, and the vicinity of the foot can be hidden. In addition, since the movable member 48 of the stopper mechanism 46 only needs to move about half the height of the vertical frame 18, the blind 14 can be easily moved up and down. The blind 14 can be stopped at an arbitrary position between FIGS. 1 and 2 by operating the stopper mechanism 46.

[0008]

As has been described above, according to the present invention, it is not necessary to fully open the blind when looking at the other side, and it is only necessary to lower the blind to the required height. Only the view can be secured. Further, by operating the movable member up and down by half at the maximum, opening and closing can be performed, so that the operation becomes easy.
