Japanese Patent Laid-Open No. 10-54186

  However, in the vertical blind described in Patent Document 1, the translucent louver suspended from the second carrier is provided so that the louver is always substantially parallel to the longitudinal direction of the head rail. The gap between the opaque louvers suspended from the first carrier is almost always closed. For this reason, there exists a subject that it cannot be made into the open / closed state which prevents incidence | injection of direct light in the state which opened all the louvers in the state substantially orthogonal to the longitudinal direction of the head rail, and ensured the view of the other side.

  The present invention has been made in view of such a problem, and it is possible to prevent the inside of the room from becoming completely visible without providing a gap between the louvers, and to ensure a view on the opposite side by providing a gap between the louvers. The present invention provides a vertical blind that can be switched between possible states.

In order to achieve the above-mentioned object, the invention according to claim 1 is a vertical blind in which a louver is suspended and supported from each of a plurality of carriers arranged to be movable in a head rail.

A carrier other than the first carrier (referred to as a second carrier) is provided with a biasing means that biases the rotation of the louver so that the louver maintains a state substantially orthogonal to the longitudinal direction of the head rail. To do.

  According to a second aspect of the present invention, in the first aspect, the first louver suspended from the first carrier pushes the second louver suspended from the second carrier while rotating. Is rotatable to a state substantially parallel to the longitudinal direction of the head rail.

According to a third aspect of the invention, in what according to claim 2, wherein, when the first louver is rotated so as to be substantially perpendicular angle from a substantially parallel angles to the longitudinal direction of the head rail, the second louvers biases The urging force of the means rotates while following the rotation of the first louver while contacting the first louver.

The invention of claim 4, wherein, in one of claim 2 or 3 Symbol mounting, and wherein the first louvers is translucent.

  According to the present invention, since the second louver suspended from the second carrier is urged to rotate by the urging means so as to be substantially orthogonal to the longitudinal direction of the head rail, When the first louver suspended from the carrier is not brought into contact with the second louver, a gap is formed between the first louver and the second louver, so that the view on the opposite side can be viewed from the gap without using the louver. Can be secured. Further, when the first louver is rotated in a direction parallel to the longitudinal direction of the head rail, a gap can be prevented between the first louver and the second louver. It can be prevented from becoming completely visible.

  According to the second aspect of the present invention, when the first louver is rotated to a state substantially parallel to the longitudinal direction of the head rail, the second louver is pressed by the first louver and the biasing means is applied. Because it can rotate to a state that is substantially parallel to the longitudinal direction of the head rail against the force, all louvers can be in a closed state that is substantially parallel to the longitudinal direction of the head rail. it can.

  According to the invention described in claim 3, the second louver is also moved in the longitudinal direction of the head rail by the urging force of the urging means only by rotating the first louver to a state substantially orthogonal to the longitudinal direction of the head rail. Therefore, all the louvers can be held in an open state substantially orthogonal to the longitudinal direction of the head rail.

  According to the fourth aspect of the present invention, when the first louver is rotated to a position where the adjacent second louvers can be closed, the vertical blind is closed only by the semitransparent first louver. As a result, the interior can be seen from the other side of the vertical blind while ensuring a certain level of privacy, without making the room completely visible from the opposite side.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view of a main part showing an embodiment of a vertical blind according to the present invention, FIG. 2 is a partial sectional view of a first carrier, and FIG. 3 is a partial sectional view of a second carrier.

  In the figure, reference numeral 10 denotes a head rail having a central portion opened at the bottom surface in the longitudinal direction. In the head rail 10, a rotating shaft 14 as a driving means is provided at the end of the head rail 10 in the longitudinal direction. It is supported rotatably by a non-bearing bearing. Three grooves extending in the longitudinal direction are formed on the outer peripheral surface of the rotary shaft 14, and one end of the rotary shaft 14 is connected to a drive gear (not shown) at one end of the head rail 10. The rotary shaft 14 can be rotationally driven by rotating the drive gear by operating the rotary operation rod 15 connected through the joint.

  In the head rail 10, a plurality of carriers are arranged so as to penetrate the rotation shaft 14 and move in the longitudinal direction thereof, and alternately become a first carrier 16 and a second carrier 17. The carrier on the other end side of the head rail 10 is a master carrier 17a.

  The master carrier 17a and the carriers 16 and 17 are formed with through holes 18a, 19a and 18, 19 on the left and right in the width direction, respectively, and the open / close cord 20 passes through the through holes 18 and 19. One end of the opening / closing cord 20 is fixed in the master carrier 17a by forming a knot inside the through hole 19a of the master carrier 17a, and the other end of the opening / closing cord 20 is an end facing the end cover 10a of the head rail 10. Is turned back in the cover 10a, passes through the through holes 18a, 18, 18,..., Is led out from one end of the head rail 10, passes through the cord weight 21, and is introduced into the head rail 10 again. , 19,..., And a knot is formed inside the through-hole 19a of the master carrier 17a to be fixed in the master carrier 17a.

  Each of the carriers 16 and 17 is connected so as to be separated or accessible with a predetermined interval determined by a spacer link 44 serving as an interval holding member as a maximum interval. Therefore, by operating the opening / closing cord 20 led out from one end of the head rail 10, the master carrier 17a can be moved along the head rail 10, and the other carriers 16, 17 are moved along with the movement of the master carrier 17a. The other carriers 16 and 17 can be moved along the head rail 10 by being pulled through the spacer link 44 or pressed by the master carrier 17a. In the following description, it is assumed that the carriers 16 and 17 including the master carrier 17a are in a separated state in principle. In a state where the carriers 16 and 17 including the master carrier 17a are separated from each other, the width of the first louver 40 is set longer than the interval between the second carriers 17.

  The first carrier 16 includes a rotation transmission mechanism 28 including a worm 24 having a center hole 24 a formed with a rib that engages with a groove of the rotation shaft 14 and a worm wheel 26 that meshes with the worm 24. A hook 30 that can rotate integrally with the worm wheel 26 around the vertical axis is connected to a lower portion of the worm wheel 26 and protrudes downward from the first carrier 16. A semitransparent first louver 40 is suspended from the first carrier 16 via a hook 30. When the rotary shaft 14 is rotated by operating the rotary operation rod 15, this rotation is transmitted to the hook 30 via the rotation transmission mechanism 28, and the first louver 40 rotates about the vertical axis in the corresponding direction. ing.

  A through hole 32 is formed in the second carrier 17 so as to pass through the rotating shaft 14 loosely. A hook 34 projects downward from the second carrier 17 so as to be rotatable around the vertical axis with respect to the second carrier 17. ing. The second carrier 17 is not provided with a rotation transmission mechanism 28. An opaque second louver 42 is suspended from the second carrier 17 including the master carrier 17 a via a hook 34.

  The hook shaft 35 of the hook 34 of the second carrier 17 is provided with a spring 45 as urging means. The spring 45 is set so that the second louver 42 is orthogonal to the longitudinal direction of the head rail 10 in a state where the initial winding is not applied (initial state). When the hook shaft 35 is rotated together with the second louver 42, the spring 45 is tightened or expanded depending on the rotation direction of the second louver 42, and the hook shaft 35 is rotated by the restoring force to return to the initial state from this state. The two louvers 42 are returned so as to be in a state orthogonal to the longitudinal direction of the head rail 10.

Next, the operation of this embodiment will be described with reference to FIG.
FIG. 4A shows a completely closed state in which all the louvers 40 and 42 are substantially parallel to the longitudinal direction of the head rail 10. In this state, the semitransparent first louver 40 is superimposed on the adjacent opaque second louver 42, and the opaque second louver 42 shields the outside from the room. At this time, the second louver 42 is held in a state substantially parallel to the longitudinal direction of the head rail 10 against the urging force of the spring 45 by overlapping with the first louver 40.

  When the rotary operation rod 15 is operated from the state of FIG. 4A to rotate the rotary shaft 14 and the first louver 40 is rotated clockwise (thin arrow in the figure), as shown in FIG. 4B. Further, the second louver 42 rotates so as to follow the rotation of the first louver 40 while being in contact with the first louver 40 by the biasing force of the spring 45 in the direction of the thick arrow in the drawing. Then, when the second louver 42 shown in FIG. 4C is rotated until the second louver 42 is substantially orthogonal to the longitudinal direction of the head rail 10, the spring 45 returns to the initial state, so the second louver 42 stops rotating. To do. In this state, the first louver 40 closes the gap between the second louvers 42, and the vertical blind is closed only by the translucent first louver 40. It is possible to take in the light from the other side of the vertical blinds and look at the scenery while ensuring a certain level of privacy without becoming visible.

  If the rotation operation of the rotation operation rod 15 is further continued from FIG. 4C as shown in FIGS. 4D and 4E, the first louver 40 rotates alone and does not contact the second louver 42. It becomes a state. In this state, the second louver 42 is urged so as to be orthogonal to the longitudinal direction of the head rail 10, and the first louver 40 is not in contact with the second louver 42. A gap is formed between the two louvers 42 and a view on the opposite side can be ensured without the first louvers 40.

  Thus, only by rotating the first louver 40 to a state orthogonal to the longitudinal direction of the head rail 10, the second louver 42 is maintained substantially orthogonal to the longitudinal direction of the head rail by the biasing force of the spring 45. Therefore, all the louvers 40 and 42 can be held in an open state substantially orthogonal to the longitudinal direction of the head rail 10.

  When the first louver 40 is further rotated by operating the rotation operating rod 15, as shown in FIGS. 4 (f) and 4 (g), the second louver 42 is urged by the biasing force in the direction of the thick arrow in the figure. The second louver 42 is pushed by the first louver 40 and rotates together with the first louver 40 while keeping in contact with the first louver 40. Then, as shown in FIG. 4 (h), the louvers 40, 42 are completely closed in a direction reversed by 180 degrees from the direction of the louvers 40, 42 shown in FIG. 4 (a).

  Thus, by rotating the first louver 40 to a state substantially parallel to the longitudinal direction of the head rail 10, the second louver 42 is pushed by the first louver 40 and the longitudinal direction of the head rail 10. Therefore, all the louvers 40, 42 can be completely closed.

  As described above, according to the present embodiment, a state in which the interior is prevented from being completely exposed without providing a gap between the louvers 40 and 42 and a view on the opposite side by providing a gap between the louvers 40 and 42 are provided. The state that can be secured can be switched by the rotation of the first louver 40, and the variation of the operation of the vertical blind can be increased.

It is a principal part perspective view showing embodiment of the vertical blind of this invention. It is a fragmentary sectional view of the 1st career. It is a fragmentary sectional view of the 2nd career. (A), (b), (c), (d), (e), (f), (g), (h) is a plane explanatory view of a louver showing an operation pattern of the present embodiment.
