Description

  The present invention relates to a vertical blind, and in particular, a plurality of carriers are attached to the inside of a glass door or the like mounted in an opening through which external light enters, so as to be movable laterally along the opening, and a slat is attached to each of the carriers. The present invention relates to a vertical blind supported by suspension.

  Conventionally, a plurality of carriers slidably combined with a moving shaft and a rotating operation shaft in a carrier case disposed laterally on the upper portion, and these carriers move along with the movement of the corresponding carriers and are transferred to the carriers. Vertical blinds with slats that rotate relative to them are known. The vertical blind is configured to use a large number of vertically suspended slats as a light-shielding member, inside the carrier case, a moving shaft for opening and closing the blinds in the length direction, and for rotating the slats. And a rotary operation shaft. In addition, the blinds can be opened and closed between the open state of the blinds gathered on the base end side in the longitudinal direction of the carrier case and the closed states of the blinds arranged almost evenly over the entire length of the carrier case. By rotating the rotation operation shaft in the closed state, the louver can be rotated around the vertical axis, thereby adjusting the dimming state.

  Here, in the conventional vertical blind, the slats suspended by the carrier are moved in one row in the length direction of the carrier case, and all the slats are closed and light-shielded. These slats are parallel to the plane on the opening side, and light shielding is performed in a state where adjacent slats are slightly overlapped or substantially aligned with each other. Therefore, in the closed state, external light is almost completely blocked regardless of the incident angle.

  In general, a vertical blind arranged in a window or opening on the south side always blocks light regardless of the incident angle even if the incident light moves from east to west. That is, light is always blocked regardless of the incident angle of external light. For this reason, light cannot be made incident or blocked according to the incident angle of light.

  An object of the present invention is to provide a vertical blind in which external light is blocked or incident according to the incident direction of light incident through the opening side.

  Another problem of the present invention is that when there is an opening along the south side, outside light from the east side and outside light from the west side are guided to the inside without blocking, and light from the south side is It is to provide a vertical blind designed to block off.

  Still another subject of the present invention is to introduce the light from the east in the morning and the light from the west in the evening into the interior, and block light rays perpendicular to the opening from the south, thereby It is to provide a vertical blind designed to reduce temperature changes.

  The above-described problems and other problems of the present invention will be made clear by the technical idea of the present invention described below and the embodiments thereof.

The main invention of the present application is a vertical blind in which a plurality of carriers are attached to the inside of an opening into which external light enters, and the slats are suspended and supported on the carriers.
The present invention relates to a vertical blind in which guide means are provided on the outer side and the inner side, respectively, and the slats are suspendably supported in two rows of the outer side and the inner side.

  Here, an outer moving unit is constituted by the outer moving shaft and the outer rotating operation shaft, and an outer carrier that supports the slats of the outer row is suspended and supported by the inner moving shaft and the inner rotating operation shaft. An inner moving unit may be configured, and an inner carrier that suspends and supports the inner row of slats may be movably supported. The outer row slats suspended and supported by the outer carrier and the inner row slats suspended and supported by the inner carrier may be alternately arranged in the moving direction. Further, light incident from the direction perpendicular to the moving direction of the carrier through the opening is blocked by the slats in the outer row and the slats in the inner row, and is oblique to the moving direction of the carrier through the opening. Light incident from a direction may be incident on the inside through a gap between the outer row of slats and the inner row of slats.

  The distance between the outer moving unit and the inner moving unit in the direction perpendicular to the moving direction may be adjustable by movement adjusting means. The movement adjusting means guides at least one of the outer unit supporting the outer slat and the inner unit supporting the inner slat so as to be movable in a direction perpendicular to the moving direction of the slat; It is comprised from the adjustment lever attached to one of the said outer unit and the said inner unit, and the action | operation part of the said adjustment lever may engage with the other long hole. Further, the movement adjusting means is a pair of rotating bodies that are rotatable by a horizontal support shaft, and the pair of rotating bodies are arranged to face the outer unit and the end of the inner unit, The outer unit and the inner unit may be rotatably supported at positions symmetrical with respect to the center.

The main invention of the present application is a vertical blind in which a plurality of carriers are attached to the inside of an opening into which external light enters, and the slats are suspended and supported on the carriers.
Guide means are provided on the outer side and the inner side of the opening, respectively, and the slats are suspended and supported movably in two rows of the outer side and the inner side.

  Therefore, such a vertical blind has a blind structure in which slats are arranged in two rows along the inside of the opening. Accordingly, by shifting the positions of the two rows of slats in the closed state, light from an oblique direction can be incident and light from a right angle direction can be blocked. Therefore, when the opening is formed along the south side, the light from the east side in the morning and the light from the west side in the evening are led into the interior, and the light from the south side in the daytime is completely blocked.

Sprocket wheels 31 and 32 are fixed to the outer rotation operation shaft 12 and the inner rotation operation shaft 14, respectively, and a roller chain 33 is wound around the sprocket wheels 31 and 32.

  The outer carrier 37 and the outer lead carrier 38 are supported by the outer moving shaft 11 and the outer rotating operation shaft 12 in the carrier case 10. The outer carrier 37 is not moved by the outer moving shaft 11, whereas the outer lead carrier 38 is moved by the outer moving shaft 11 and pulls the outer carrier 37. The outer carrier 37 and the outer lead carrier 38 are respectively provided with hooks 39 at their lower end portions as shown in FIG. 1, and the outer slats 40 are suspended by these hooks 39. Similarly, the inner carrier 41 and the inner lead carrier 42 are movably supported by the inner moving shaft 13 and the inner rotating operation shaft 14. Further, hooks 39 are attached to the inner carrier 41 and the inner lead carrier 42, and these hooks 39 suspend inner slats 44. The outer slat 40 and the inner slat 44 are connected to each other by a connecting string 45. Weight sheets 46 are attached to the lower ends of the outer slat 40 and the inner slat 44, respectively.

  Next, the structure of the outer carrier 37 and the inner carrier 41 for suspending and moving the outer slat 40 and the inner slat 44 will be described with reference to FIG. The outer carrier 37 and the inner carrier 41 have the same structure and include a housing 50 assembled by a pair of halves. A rectangular recess 51 is formed on the inner surface of the housing 50. A guide plate 52 is fitted into the rectangular recess 51. The guide plate 52 has a circular hole 53 at the center thereof, and the outer moving shaft 11 or the inner moving shaft 13 is inserted through the circular hole 53, and relative idling is performed by the circular hole 53. It is trying to be. A circular recess 54 is formed on the wall surface of the housing 50, and a worm wheel 55 is rotatably held in the recess 54. The worm wheel 55 meshes with a worm 57 that is held in a semi-cylindrical recess 56 formed on the surface of the housing 50. A connecting shaft 58 is formed at the lower end of the worm 57, and the hook 39 is attached to the lower end of the connecting shaft 58. The hook 39 suspends and supports the outer slat 40 or the inner slat 44.

  Next, the outer lead carrier 38 and the inner lead carrier 42 will be described with reference to FIG. Both of these lead carriers 38 and 42 have the same structure. An engagement plate 60 is fitted into a rectangular recess 51 formed on the wall surface of the half-shaped housing 50. The engagement plate 60 has a circular hole having a locking claw 61 on the inner peripheral surface, and the outer moving shaft 11 or the inner moving shaft 13 is inserted through the circular hole. That is, both the outer moving shaft 11 and the inner moving shaft 13 are feed screws, and the engaging claws 61 of the engaging plate 60 are engaged with the screw groove portions, whereby the screw feeding operation is achieved. ing. Other structures of the outer lead carrier 38 and the inner lead carrier 42 are the same as those of the outer carrier 37 and the inner carrier 41.

  Next, the opening / closing operation of the vertical blind according to the above configuration will be described. The inner moving operation wheel 21 is rotationally driven by pulling the moving operation string 23 shown in FIG. 1 in the forward direction or the reverse direction. Since the moving operation wheel 21 is fixed to the inner moving shaft 13, the inner moving shaft 13 is rotationally driven. Moreover, the rotation of the inner moving shaft 13 is transmitted to the outer moving shaft 11 via the sprocket wheels 28 and 27 and the roller chain 29, and the outer moving shaft 11 is rotationally driven in the same direction.

  The outer moving shaft 11 and the inner moving shaft 13 are feed screws having a thread groove on the outer peripheral surface, and these screw portions are engaged with the engaging claws 61 of the engaging plates 60 of the lead carriers 38 and 42 shown in FIG. ing. Accordingly, by rotation of the outer moving shaft 11 and the inner moving shaft 13, both the outer lead carrier 38 and the inner lead carrier 42 are pushed or pulled in the axial direction of the outer moving shaft 11 and the inner moving shaft 13. On the other hand, in the outer carrier 37 and the inner carrier 41 of FIG. 3, the holes of the guide plate 52 through which the corresponding outer moving shaft 11 and inner moving shaft 13 pass are simply circular holes. It will not be moved.

  When the leading outer lead carrier 38 and the leading inner lead carrier 42 are moved in the axial direction by the outer moving shaft 11 and the inner moving shaft 13, these lead carriers 38 and 42 are suspended by hooks 39. The outer slat 40 and the inner slat 44 are moved together with the outer lead carrier 38 and the inner lead carrier 42, respectively. Then, the outer slat 40 and the inner slat 44 on the distal end side pull the next outer slat 40 and the inner slat 44 which are connected by the connecting string 45, and the outer slat 40 and the inner slat 40 which are sequentially connected to the rear in the following manner. 44 are sequentially moved in the moving direction of the outer lead carrier 38 and the inner lead carrier 42. This operation is an opening / closing operation of the outer slat 40 and the inner slat 44.

  Next, the rotation operation of the outer slat 40 and the inner slat 44 will be described. When the rotation operation string 24 wound around the rotation operation wheel 22 attached to the end of the inner rotation operation shaft 14 shown in FIGS. 1 and 2 is pulled, the inner rotation operation shaft 14 rotates. Further, the rotation of the inner rotation operation shaft 14 is transmitted to the outer rotation operation shaft 12 via the sprockets 32 and 31 and the roller chain 33, and the outer rotation operation shaft 12 is rotated.

  The outer rotation operation shaft 12 is a square bar having a square cross section, and the rotation is transmitted to the worm wheel 55 inside the outer carrier 37 to rotate, and the worm 57 is rotated by the worm wheel 55. Then, since the rotation of the worm 57 is transmitted to the hook 39 via the connecting shaft 58, the outer slat 40 suspended by the hook 39 is rotated. Further, the worm wheel 55 inside the outer lead carrier 38 is rotated by the rotation of the outer rotation operation shaft 12, and the worm 57 is driven at a reduced speed, so that the worm 57 is connected to the worm 57 via the connecting shaft 58. The hook 39 rotates and the outer slat 40 suspended by the hook 39 is rotated.

  Next, when the inner rotation operation shaft 14 is directly rotated by the inner rotation operation wheel 22, the worm wheel 55 of the inner carrier 41 through which the inner rotation operation shaft 14 passes is rotationally driven, and the rotation of the worm wheel 55 is transferred to the worm 57. Communicated. Accordingly, the hook 39 connected to the worm 57 via the connecting shaft 58 rotates. Then, the inner slat 44 is rotated by the rotation of the hook 39.

  Further, the worm wheel 55 provided inside the inner lead carrier 42 is rotated by the rotation of the inner rotation operating shaft 14, and the worm 57 is driven at a reduced speed. Accordingly, the connecting shaft 58 connected to the worm 57 is rotationally driven, the hook 39 is rotated, and the inner slat 44 suspended by the hook 39 is rotated.

  As shown in FIG. 5, the outer slat 40 and the inner slat 44 can change their rotational postures, as shown in FIG. 5, for example, located on the south side. The rotation is switched between a direction parallel to the glass plate 65 and a direction perpendicular to the glass plate 65. Further, the outer slat 40 and the inner slat 44 are rotationally adjusted by the outer rotational operation shaft 12 and the inner rotational operation shaft 14, and are arbitrarily rotated and adjusted in directions parallel to and perpendicular to the glass plate 65 and other angles.

  FIG. 5 shows a positional relationship on the plane between the inner slat 44 and the outer slat 40 in such a vertical blind. Here, the dimension L in the direction perpendicular to the glass plate 65 between the inner slat 44 and the outer slat 40 may be in the range of 0 to 30 mm. Moreover, the dimension A of the horizontal direction parallel to the glass plate 65 of each slat 40, 44 shown by A in the same figure may be set in the range of 30-70 mm. Moreover, it is a dimension shown by B in the same figure, Comprising: The dimension of the clearance gap between the mutually adjacent slats 40 and the slats 44 may be in the range of 20-40 mm. In addition, the dimension indicated by C in the drawing and the dimension C on one side of the overlapping portion of the outer slat 40 and the inner slat 44 may be in the range of 5 to 15 mm.

  The vertical blind according to the present embodiment is particularly characterized in that it blocks or transmits light according to the incident angle of external light, as shown in FIG. For example, as shown in FIG. 6A, light incident from a right angle with respect to the glass window 65 is almost completely blocked by the outer slat 40 and the inner slat 44. This is because the lateral dimension of the outer slat 40 and the inner slat 44 is larger than the gap between the outer slats 40 and the gap between the inner slats 44. On the other hand, the incident light from the direction oblique to the glass plate 65 and the light from the direction indicated by the dotted line and the light from the direction indicated by the chain line in FIG. The light enters the room through the portion of the gap between the outer slat 40 and the inner slat 44 disposed.

  In particular, the blind according to the present embodiment is characterized in that, for example, incident light from the east in the morning enters the room through the gap between the outer slat 40 and the gap between the inner slats 44 as shown by the dotted line in FIG. 6B. As for the evening sun in the evening, the light enters the room diagonally through the gap between the outer slat 40 and the gap between the inner slats 44 as indicated by the chain line in FIG. On the other hand, the sun light around noon and light just south is shielded by the outer slat 40 and the inner slat 44 as shown in FIG. 6A and does not enter the room. Therefore, it has the effect of taking in sunlight in the morning when the temperature is low or in the evening when the temperature is decreasing, and also has the effect of blocking outside light during the day when the temperature rises. It is possible to adjust so as to reduce the change of.

  In addition, the vertical blind having such a configuration cannot be seen from the outside or seen from the inside when viewed from a straight direction when viewing the room from the outside or viewing from the inside. On the other hand, when viewed from an oblique direction, the inside from the outside or the inside to the outside looks like a slit.

Embodiment 2 (FIGS. 7 to 10)
Next, a second embodiment will be described with reference to FIGS. In this embodiment, the distance between the outer slat 40 and the inner slat 44 of the vertical blind is adjustable. Here, as shown in FIG. 7, the distance between the outer unit 71 that moves the outer slat 40 and the inner unit 72 that moves the inner slat 44 can be adjusted.

  The outer unit 71 and the inner unit 72 that are arranged in parallel to each other are supported by the guide rails 73 in the perpendicular direction that are intermittently arranged in the length direction so as to be movable and adjustable in the perpendicular direction. An adjustment lever 74 is pivotally supported via a fulcrum pin 75 at a substantially central portion in the length direction of one unit, for example, the inner unit 72. An operating pin 76 attached to the tip end portion of the adjustment lever 74 is adapted to engage with the elongated hole 77 of the other outer unit 71. Here, if both are fixed so that there is no relative movement between the outer unit 71 and the guide rail 73, the operation pin 76 on the tip side of the adjustment lever 74 is extended by rotating the adjustment lever 74. While moving in the hole 77, the inner unit 72 is moved in the length direction of the guide rail 73 with respect to the outer unit 71 by the reaction force along with the movement. As a result, the distance between the outer unit 71 and the inner unit 72 can be adjusted.

  FIG. 8A shows a state where the adjustment lever 74 is rotated and the inner unit 72 is moved so as to approach the outer unit 71. In contrast, in FIG. 8B, the inner unit 72 is moved away from the outer unit 71, and the distance between the outer slat 40 and the inner slat 44 is increased. According to such a configuration, it is possible to arbitrarily adjust the incident start position and incident end position of light incident obliquely. Alternatively, the incident angle of external light can be arbitrarily adjusted.

  Next, a modification of the above embodiment will be described with reference to FIGS. In this embodiment, a distance between the outer unit 71 and the inner unit 72 is adjusted using a pair of rotating disks 80 instead of the movement adjustment by the adjusting lever 74. That is, the outer unit 71 and the inner unit 72 are rotatably supported via a fulcrum pin 82 by a pair of rotating disks 80 that are arranged so that both ends thereof face each other. In addition, the rotating disk 80 is rotated about the support shaft 81.

  As shown in FIG. 10A, when the pair of fulcrum pins 82 are symmetrical to each other and support the outer unit 71 and the inner unit 72 in a horizontal state, the distance between them is the largest. On the other hand, when the rotating disk 80 is rotated about the support shaft 81 as shown in FIG. 10B, the horizontal distance between the outer unit 71 and the inner unit 72 gradually becomes closer. Accordingly, the distance between the outer unit 71 and the inner unit 72 can be adjusted according to the rotation angle of the rotating disk 80. At this time, the outer slat 40 of the outer unit 71 and the inner slat 44 of the inner unit 72 also move in the vertical direction. However, if the diameter of the rotating disk 80 is reduced, the outer slat 40 in the vertical direction is reduced. And the displacement between the inner slat 44 can be reduced.

  While the present invention has been described with reference to the two illustrated embodiments, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea of the present invention. For example, various changes can be made to the number and dimensions of the slats in the above embodiment. Various design changes can be made to the internal structure of each carrier.

  The present invention can be widely used as a vertical blind that is attached to the inside of a window or opening of a building and blocks outside light.
