Description

  The present invention relates to a blind that combines the functions of a slat and a fabric.

  Blinds, curtains, and the like can be cited as shields from sunlight entering the room. Among these, the blind has good shielding properties when the slat is closed, and can block not only the solar radiation but also the line of sight from the outside. Moreover, the lighting condition can be finely adjusted by adjusting the inclination angle of the slats. However, since the adjustment of the lighting condition is merely adjusting the amount of light entering the room by adjusting the tilt angle of the slats, it is not possible to expect an atmosphere such as taking in soft light. Depending on the inclination angle of the slats, the room may be visible from the outside. On the other hand, the curtain can take soft light into the room, but the lighting condition cannot be finely adjusted. Also, it is impossible to have the effect of blocking the line of sight from the outside or taking in soft light indoors in one curtain.

  As what has the advantage of such a blind and a curtain, what attached the curtain to the front side (indoor side) of the blind is known (refer patent document 1). In other words, a curtain hook is fitted to the upper box of the blind, a curtain guide ring is fitted over the vertical cord of the ladder cord hanging from the upper box at a predetermined interval in the vertical direction, and the curtain is suspended from the curtain hook and the guide ring. By attaching the curtain and the curtain, the curtain can be attached to the blind. Accordingly, the vertical cord of the ladder cord is also used as a hanging strap of the curtain. When the slat is raised, the curtain is lifted up together with the ladder cord, and when the slat is lowered, the curtain is lowered together with the ladder cord.

Japanese Utility Model Publication 3-6791

  By the way, if the curtains are simply attached to the front side of the blinds, the space required for installing them is not much different from the case where the blinds and the curtains are attached to the front and rear. For this reason, a space is required in the front-rear direction.

  Further, since the curtain is lifted when the blind is raised, the raised curtain hangs down indoors. For this reason, there has been a problem that the refreshing design inherent in the blinds cannot be maintained.

  Therefore, the present invention has been made in view of such problems, and an object of the present invention is to provide a blind having a small space required for installation and improved design.

  In order to solve the above-described problem, according to the present invention, a plurality of slats having one or more insertion holes formed in a longitudinal direction and a variable inclination angle, and the insertion holes of the plurality of slats are sequentially inserted. And a blind comprising a dough.

  According to this invention, since the cloth is inserted through the slat, the space required for the installation only needs to be about the width of the front and rear of the slat, and a large installation space is not required.

  Further, since the fabric passes through the plurality of slats sequentially, for example, when the slats are in a horizontal state, the gap between the upper and lower slats is almost covered with the fabric. For this reason, the light entering the room from between the upper and lower slats becomes soft light by the cloth, and the line of sight directed from the outside to the room is blocked by the cloth. Therefore, it is possible to block the line of sight from the outside while taking in soft light.

  In this way, the function is the same as the combination of the blind and the curtain, but the fabric is not lifted when the slat is raised, and the fabric passes through the slat when the slat is lowered. In any case, a clean design can be maintained in the same way as a general blind.

  The fabric may be suspended from the support member so as to be wound and unwound, and the plurality of slats may be moved up and down by winding and unwinding the fabric on the support member. Thereby, since the function of a raising / lowering cord can be given to cloth, a raising / lowering cord becomes unnecessary.

  A ladder tape that supports a plurality of slats in an aligned state is suspended from the support member, and the ladder tape and the fabric are alternately arranged in the longitudinal direction of the slats. The vertical tape may be wider than the distance between adjacent fabrics. As a result, a slight gap between adjacent fabrics can be closed with vertical tape. Thereby, the line of sight from the outside can be completely blocked.

  Also, the fabric may be permeable. Thereby, the line of sight from the outside can be blocked while taking in soft light between adjacent slats.

  According to the present invention, since the dough is inserted through the slats, the space required for the installation only needs to be about the width of the front and rear of the slats, and a large installation space is not required.

In addition, since the dough is only inserted through the slats, the dough is not lifted when the slats are raised, and the dough is only inserted through the slats when the slats are lowered. Can maintain a clean design as well as ordinary blinds.
The other effects of the present invention will be described in the section for carrying out the invention below.

Hereinafter, each component of the blind 100 will be described in detail.

(Winding pipe 106)
The take-up pipe 106 is a support member that supports the screen 110 and, as shown in FIG. As a result, the arrangement of the winding pipe 106 and the rotating drum 108 is alternated, so that the screen 110 connected to the winding pipe 106 and the ladder cord 114 connected to the rotating drum 108 are alternately arranged. .

(Rotating drum 108)
The three rotary drums 108 are support members that support the ladder cord 114, and are provided on the outer periphery of the winding pipe 106 so as to rotate integrally. As shown in FIG. 3, the rotary drum 108 has a disk shape, and includes a flange 108a formed on the outer periphery at both ends in the axial direction and a groove 108b formed between the flanges 108a. ing. The upper end of the ladder cord 114 is wound around the groove 108b so as to form a loop, and the flange 108a restricts the movement of the ladder cord 114 in the axial direction.

(Screen 110)
The screen 110 is made of a permeable fabric such as lace, see-through, or mesh, and four screens 110 are provided as shown in FIG. One end of each of the four screens 110 is coupled to each of the winding pipes 106 divided by the four rotating drums 108 so as to be wound and unwound, and the other end is suspended from the winding pipe 106. . The width of each screen 110 corresponds to the width of the winding pipe 106 to which each screen 110 is connected.

(Screen guide 112)
As shown in FIG. 4A, the screen guiding portion 112 includes a pair of cylindrical members 112a and 112b disposed below the winding pipe 106. As shown in FIG. 3, both ends of the pair of cylindrical members 112a and 112b are rotatably supported by the side plate 104, and the thickness of the screen 110 is approximately between the pair of cylindrical members 112a and 112b. The gap 112c is provided. The gap 112c is positioned vertically below the winding pipe 106 and directly above an insertion hole 118a of a slat 118 described later, and the screen 110 led out from the winding pipe 106 passes through the gap 112c and hangs down. Yes.

(Ladder code 114)
As shown in FIG. 4B, the ladder cord 114 is arranged at equal intervals in the vertical direction of the vertical cords 114a and 114b arranged on the front side and the rear side of the slat 118 and the vertical cords 114a and 114b. And a middle-stage cord 113 that connects the two vertical cords 114a and 114b. The upper ends of the vertical cords 114a and 114b are wound around the groove 108b of the rotary drum 108 so as to be wound and unwound in a state where a loop is formed as described above. The ladder cord 114 is suspended from the rotary drum 108, supports a plurality of slats 118 in an aligned state on the middle cord 113, and has a lower end connected to the bottom rail 120. The ladder cord 114 is tilted in conjunction with a rotating drum 108 that rotates integrally with the winding pipe 106 to rotate the slat 118.

(Ladder code guiding part 116)
As shown in FIG. 1, the ladder code guiding portion 116 is provided below the rotary drum 108, and ladder code insertion holes 116 a and 116 b through which the front and rear vertical cords 114 a and 114 b are inserted are formed at the front and rear. (See FIG. 4B). A support portion 116 c that rotatably supports the pair of cylindrical members 112 a and 112 b of the screen guide portion 112 is formed at a portion near the center of the ladder code guide portion 116.

(Slat 118)
As shown in FIG. 1, each slat 118 is formed with four insertion holes 118a along the longitudinal direction, and the position of each insertion hole 118a corresponds to each of the winding pipes 106 divided into four. It is a position to do. As shown in FIG. 2, each insertion hole 118 a has a long hole shape, and the size of each insertion hole 118 a corresponds to the width of the screen 110 depending from the winding pipe 106.

(Pulley 124)
The pulley 124 is provided between the one side plate 104 and the winding pipe 106 and is configured to transmit rotation to the winding pipe 106. Further, an endless operation chain 122 is wound around the pulley 124, and is rotated by operating the operation chain 122, and this rotation is transmitted to the winding pipe 106.

  Next, the distribution of the screen 110 will be described. The four screens 110 are similarly arranged from the corresponding winding pipes 106. That is, the other end of the screen 110 that hangs down from the winding pipe 106 passes through the gap 112c of the screen guiding portion 112 and extends from the top to the bottom through the insertion hole 118a of each slat 118, as shown in FIG. Are sequentially inserted and coupled to the bottom rail 120. Since the gap 112c of the screen guiding portion 112 is located directly above the insertion hole 118a of each slat 118, the screen 110 is inserted through the insertion hole 118a in a state where it is suspended linearly from the screen guiding portion 112. Thereby, since the screen 110 which penetrates the slat 118 does not be in a bent state, a good appearance is obtained.

  By winding and unwinding the screens 110 arranged in this way around the winding pipe 106, the screen 110 moves up and down, so that the bottom rail 120 and the slat 118 move up and down. Therefore, since the screen 110 serves as a lifting / lowering cord used for lifting / lowering the slats in a general blind, the lifting / lowering cord becomes unnecessary.

Next, the operation of this embodiment will be described with reference to FIGS.
When the horizontal slat 118 as shown in FIGS. 3 and 4 is closed, one of the operation chains 122 arranged at the front and rear is operated to move the winding pipe 106 in one direction via the pulley 124. Rotate. As a result, the rotating drum 108 rotates integrally with the winding pipe 106, and as shown in FIG. 6B, the vertical cord 114a on the front side of the ladder cord 114 is wound around the rotating drum 108 and the rear side. The vertical cord 114b is unwound from the rotary drum 108, and the slat 118 rotates. When the rotating drum 108 rotates by a predetermined angle, the slat 118 is fully closed as shown in FIGS. 5 and 6A. In this state, the ends of the adjacent slats 118 overlap each other, but the screen 110 is exposed because the slats 118 do not overlap the insertion hole 118a. Further, even if the slat 118 rotates until the fully closed state as described above, the position where the screen 110 hangs down and the position of the insertion hole 118a coincide with each other as shown in FIG. Is maintained without sagging.

  Next, when the slat 118 is folded up, first, the other of the operation chains 122 is operated. As a result, the take-up pipe 106 rotates in the other direction, and the rotary drum 108 rotates in the other direction together with the take-up pipe 106. As a result, the slat 118 rotates approximately 180 degrees, and the winding drum 106 continues to rotate together with the rotating drum 108. At this time, since the upper ends of the two vertical cords 114a and 114b of the ladder cord 114 slip on the rotary drum 108, the screen 110 is wound around the winding pipe 106 while the slat 118 is maintained in a fully closed state. The bottom rail 120 and the slat 118 rise. As shown in FIG. 7, when the uppermost slat 118 abuts on the ladder cord guiding portion 116, the winding of the screen 110 onto the winding pipe 106 is restricted, and the slat 118 is in the most elevated state. . As described above, the screen 110 is wound around the take-up pipe 106 so that the slat 118 is lifted, so that the screen 110 is kept in a tension state between the take-up pipe 106 and the bottom rail 120 and is loosened. There is no. Therefore, the appearance when the slats 118 are folded up is the same as a general blind that does not have the screen 110, and a clean design can be maintained.

  As described above, according to the present embodiment, by inserting each screen 110 through each slat 118, for example, even between the slats 118, the space between adjacent slats 118 is substantially covered by the screen 110. It becomes a state. As a result, light entering the room from between the adjacent slats 118 enters through the screen 110, so soft light is taken in. When the slats 118 are not completely closed, a general brand may see the room from between the adjacent slats 118, but the screen 110 is between the adjacent slats 118. The line of sight from the outside can be blocked. Thus, the blind 100 of this embodiment can block the line of sight from the outside while taking in soft light. Further, since the screen 110 is inserted through the slat 118, a clean design similar to that of a general blind can be maintained.

  Further, since the screen 110 is inserted into the slat 118, it is not necessary to arrange the screen 110 and the slat 118 in the front-rear direction. For this reason, the size of the mounting space for the blind 100 may be the size of the mounting space for a general slat-only blind.

(Second Embodiment)
Next, a blind 100 according to a second embodiment will be described with reference to FIGS. The present embodiment is characterized by the ladder tape 200 corresponding to the ladder cord 114 in the blind 100 according to the first embodiment. Here, only the configuration of the ladder tape 200 will be described, and the other parts are the same as those in the first embodiment, and therefore, redundant description will be omitted.

  The ladder tape 200 of this embodiment is provided on each of the three rotating drums 108 as shown in FIG. As shown in FIGS. 9 and 10, the ladder tape 200 includes a rotary cord portion 210 that is wound around the groove 108 b of the rotary drum 108 so as to be wound and unwound, and an intermediate cord 230 that supports the slat 118. And a wide tape portion 220 provided. Both end portions of the rotation cord portion 210 are inserted through the ladder cord insertion holes 116 a and 116 b and are connected to the upper side of the uppermost middle cord 230 of the wide tape portion 220, respectively. The wide tape portion 220 has an upper end wound around the flange 108 a of the rotary drum 108 and connected, and a lower end connected to the bottom rail 120.

  As shown in FIGS. 8 and 9, the wide tape portion 220 is slightly wider than the interval between the adjacent screens 110, and the gap between the adjacent screens 110 is closed by the wide tape portion 220.

  As described above, according to the present embodiment, the ladder tape 200 arranged alternately with the screen 110 is provided with the wide tape portion 220, so that the gap between the adjacent screens 110 can be closed with the wide tape portion 220. Thereby, it is possible to prevent light leakage from the gap and to block the line of sight from the outside.

(Third embodiment)
Next, a blind 100 according to a third embodiment will be described with reference to FIGS. 11 and 12. The present embodiment is characterized in that a balance 300 is attached to the blind 100 according to the first embodiment, and the other parts are the same as those of the first embodiment, and therefore redundant description is made. Is omitted.

  As shown in FIG. 11, the balance 300 is disposed so as to cover from the set frame 102 to the ladder code guiding portion 116, and as shown in FIG. 12, the balance bracket provided on the balance 300. 310 is detachably attached to the set frame 102.

  Thus, according to the present embodiment, by providing the balance 300 on the blind 100, the balance 300 can be hidden from the set frame 102 to the ladder code guiding portion 116, so that the appearance of the blind 100 is improved.

(Fourth embodiment)
Next, a blind 100 according to a fourth embodiment will be described with reference to FIG. The present embodiment is characterized in that the screen 110 and the bottom rail 120 of the blind 100 according to the first embodiment can be separated, and the screen 110 and the slat 118 are moved up and down separately. Yes, and other parts are the same as those in the first embodiment, and a duplicate description is omitted.

  As shown in FIG. 13, a connecting member 400 is attached to the lower end of the screen 110, and the connecting member 400 is connected to the bottom rail 120. When the screen 110 is wound up by the winding pipe 106, the connecting member 400 is detached from the bottom rail 120, and only the screen 110 is raised (see FIG. 13C). On the other hand, when the screen 110 is unwound by the winding pipe 106, the screen 110 is lowered and the connecting member 400 is connected to the bottom rail 120. A magnet or the like can be used as the connecting member 400.

  The rotating drum 108 is provided between the winding pipe 106 and the ladder cord guiding portion 116. As shown in FIG. 13A, the ladder cord 114 is wound around the rotating drum 108 by a predetermined angle. And unrollable. Furthermore, as shown in FIG. 13B, one end of a lifting / lowering cord 500 is connected to the rotating drum 108 so as to be wound and unwound. The other end of the lifting / lowering cord 500 is provided so as to be movable relative to the vertical cord 114b behind the ladder cord 114 and connected to the bottom rail 120.

  In this embodiment, since the operation of the winding pipe 106 and the rotating drum 108 is a separate system, two operation systems are provided. For example, the operation system of the winding pipe 106 may be the same pulley 124 and operation chain 122 as in the first embodiment, and another pulley and operation chain may be provided for the operation of the rotating drum 108.

Next, the operation of this embodiment will be described.
When the screen 110 is in the lowest lowered position, the connecting member 400 is connected to the bottom rail 120 as shown in FIGS.

  When the operation unit (not shown) is operated to rotate the winding pipe 106 in one direction to wind the screen 110, the connection between the connecting member 400 and the bottom rail 120 is released and the screen 110 is wound. . As shown in FIG. 13C, the screen 110 rises to a position where the connecting member 400 abuts on the ladder code guiding portion 116. Thereby, since the blind 100 becomes a form of a general blind provided with only the slat 118, it can be used similarly to a general blind.

  Next, when the winding pipe 106 is rotated in the other direction, the screen 110 is unwound. When the screen 110 is lowered to the lowest position, the connecting member 400 is connected to the bottom rail 120 as shown in FIGS. 13A and 13B. Thus, the blind 100 in which the screen 110 is inserted through the slat 118 is configured.

Next, the raising / lowering operation | movement of the slat 118 is demonstrated.
When the slat 118 is raised, an operation unit (not shown) is operated to rotate the rotating drum 108 in one direction. As a result, the ladder cord 114 is wound and unwound by a predetermined angle on the rotary drum 108 and tilted, and then the state is maintained. On the other hand, since the lifting / lowering cord 500 is continuously wound around the rotary drum 108, the bottom rail 120 and the slat 118 are raised.

  Next, when lowering the slat 118, an operation unit (not shown) is operated to rotate the rotary drum 108 in the other direction. Thereby, the ladder cord 114 maintains its state after tilting in the opposite direction. On the other hand, since the lifting / lowering cord 500 is continuously unwound from the rotary drum 108, the bottom rail 120 and the slat 118 are lowered. As described above, the slats can be moved up and down in the same manner as a general blind.

  As described above, according to the present embodiment, the screen 110 and the bottom rail 120 are separable, and the screen 110 and the slat 118 are moved up and down separately, so that one blind 100 can have a screen. Both the blind having both 110 and the slat 118 and the brand having only the slat can be provided.

  Further, the rotation of the winding pipe 106 may be interlocked with the rotation of the rotating drum 108. In this case, when the bottom rail 120 and the slat 118 are raised, the screen 110 can be raised while being wound around the winding pipe 106 together. Further, an opening formed in the bottom rail may be inserted without connecting the lower end of the screen 110 to the bottom rail 120. In this case, when the bottom rail 120 and the slat 118 are raised, only the screen 110 can be lowered.

  As mentioned above, although preferred embodiment of this invention was described referring an accompanying drawing, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. is there.

  In the above embodiment, the screen 110 is made of a permeable cloth, but an impermeable cloth such as drape or any cloth can be used.

  Moreover, although the said embodiment demonstrated the example which applied this invention to the horizontal blind, you may apply to a vertical blind. That is, an insertion hole may be provided in the louver (corresponding to a slat) of the vertical blind so that the cloth is inserted.
