(overall structure)
FIG. 1 is a front view showing a schematic configuration of a horizontal blind according to an embodiment of the present invention. Here, the electric horizontal blind shown in FIG. 1 will be described as an example of the horizontal blind that enables partial lighting according to the present invention, but the present invention is not limited to the example shown in FIG.

For example, the elevating shaft for winding or rewinding the elevating cord and the angle adjusting shaft for moving the ladder cord supporting the slats are not limited to the electric horizontal blind having one drive shaft, and these elevating and lowering. An electric horizontal blind may be used as a two-axis drive shaft having a shaft and an angle adjustment shaft separately. Further, the blind is not limited to the electric type, and may be a horizontal blind that can manually raise and lower multiple stages of slats and adjust the angle. That is, the horizontal blind according to the present invention has a structure capable of raising and lowering and adjusting the angle of multiple stages of slats regardless of whether it is an electric type or a manually operated type. Note that it is applicable.

In the electric horizontal blind shown in FIG. 1, a multi-stage slats 3 are suspended and supported via ladder cords 2 hanging from both left and right side portions and a central portion of the head box 1, and a bottom rail 4 is provided at the lower end of the ladder cord 2. Is suspended and supported.

In the vicinity of the ladder cords 2 on both the left and right sides of the head box 1, the elevating cord 5 is suspended and supported from the head box 1, and the bottom rail 4 is attached to the lower end of the elevating cord 5. Although a tape-shaped cord is illustrated as the elevating cord 5 in FIG. 1, a string-shaped cord may be used. Therefore, when the elevating cord 5 is referred to, a tape-shaped or string-shaped cord is included.

A support member 6 for suspending the ladder cord 2 and the elevating cord 5 is arranged in the head box 1, and a hexagonal rod-shaped drive shaft 7 is inserted through the support member 6.

The support member 6 includes a tilt drum 61 for suspending the ladder cord 2 so as to be movable in the vertical direction, and a winding drum 62 for winding or rewinding the elevating cord 5. The tilt drum 61 and the take-up drum 62 rotate as the drive shaft 7 rotates.

A motor 8 is arranged on one end side of the head box 1, and one end of the drive shaft 7 is connected to the output shaft of the motor 8. Then, the drive shaft 7 is forward-reversed based on the operation of the motor 8, and each slat 3 is rotated via the ladder cord 2 based on the forward / reverse rotation of the drive shaft 7, or the bottom rail 4 is rotated via the elevating cord 5. Is raised and lowered to raise and lower the slat 3.

Although not shown, a control controller having a built-in CPU and a power supply unit for supplying power to the control controller and the motor 8 are arranged in the head box 1. Then, this control controller has a function of monitoring the output value of the upper limit position detection sensor 13 that detects the upper limit position of the slat 3, and an encoder that detects the rotation amount and the rotation speed of the drive shaft 7 arranged in the head box 1. A function of monitoring the output value of the 14 and a function of monitoring the output values of the upper limit position detection sensor 13 and the encoder 14 and controlling the drive of the motor 8 based on an operation signal from an operation switch (not shown). Have.

By the way, in the horizontal blind according to the present invention illustrated in FIG. 1, an insertion hole 3a for inserting the elevating cord 5 is provided in a substantially central portion in the front-rear direction of each slat 3, and some slat 3s have an insertion hole 3a. The insertion hole 3a is provided with a cord guide 20 that functions as a partial lighting member according to the present invention.

(Code guide that functions as a member for partial lighting)
The slat 3 provided with the cord guide 20 is configured as a slat for partial lighting. In the example shown in FIG. 1, the slat 3 in the third and fifth stages from the top where the code guide 20 is installed is configured as a slat for partial lighting. Such a partial daylighting slat can be set for any slat 3 among the multi-stage slat 3. The slats 3 on which the code guide 20 is installed can be changed by the user.

Further, in the example shown in FIG. 1, two elevating cords 5 are hung from the head box 1, and all the insertion holes through which the respective elevating cords 5 are inserted into the slat 3 configured as the partial lighting slat. A code guide 20 is installed in 3a. In a configuration in which three or more elevating cords 5 are hung down, it is preferable to install the cord guide 20 so that the left and right balance can be achieved. It is more preferable to install 20.

FIG. 2 shows a schematic configuration of a slats 3 equipped with a cord guide 20 that functions as a member for partial lighting in the horizontal blind of the present embodiment. Each slat 3 is placed on a weft thread 2a connected between a pair of ladder cords 2 in the front-rear direction, and an insertion hole 3a through which an elevating cord 5 is inserted is provided in a substantially central portion of each slat 3 in the front-rear direction. ing. Then, the slat 3 having the cord guide 20 attached to the insertion hole 3a functions as a slat for partial lighting.

FIG. 3A shows an assembly diagram when the cord guide 20 is assembled to the slat 3, and FIGS. 3B and 3C show a plan view showing a schematic configuration of the cord guide 20 and A. -A'Cross section is shown.

As shown in FIG. 3A, the cord guide 20 can be assembled into the insertion hole 3a of the slats 3 and can also be removed. That is, the cord guide 20 is made of synthetic resin and has a pair of arm portions 22 extending in a bifurcated shape from the base portion 21 as shown in FIGS. 3 (a) and 3 (b). Then, as shown in FIGS. 3A and 3C, the claw portion 23 provided below the base portion 21 and the claw portion 24 provided below each arm portion 22 elastically deform the arm portion 22. As a result, it can be assembled into the insertion hole 3a of the slats 3. The pair of arm portions 22 are assembled by elastically deforming the insertion hole 3a by an inner wall portion 22a having a curved surface on the contact surface side with the elevating cord 5 and having a thickness in the height direction and a tip portion 22b thereof. When the slats 3 are tilted, an opening smaller than the opening area of the insertion hole 3a is formed, whereby a predetermined contact resistance is generated with respect to the elevating cord 5 when the slats 3 are tilted.

That is, as shown in FIG. 4A, when the slats 3 are rotated from the horizontal state to the reverse fully closed state, the contact resistance between the cord guide 20 and the elevating cord 5 increases.

Continuing from the state shown in FIG. 4 (a), when the elevating cord 5 is moved in the ascending direction within the pitch interval of the multi-stage slat 3 as shown in FIG. 4 (b), the elevating cord 5 is moved. Then, the slat 3 to which the cord guide 20 is attached also separates from the support of the weft thread 2a and moves upward. At this time, the slat 3 not equipped with the cord guide 20 can move the elevating cord 5 within a range in which the cord guide 20 is not attached, and the slat 3 equipped with the cord guide 20 is relative to a position close to the slat 3 immediately above the slat 3. You can move. Then, among the multi-stage slat 3 in the reverse fully closed state, the lower part of the slat 3 equipped with the cord guide 20 is in the state of partial lighting, and therefore the slat 3 equipped with the cord guide 20 functions as a slat for partial lighting.

Continuing from the state shown in FIG. 4 (b), when the slats 3 are rotated from the partially illuminated state to the horizontal state as shown in FIG. 4 (c), the contact resistance decreases and becomes smaller, and the partial lighting The slats 3 that have moved so as to return to the original position supported by the weft 2a. Even when the slat 3 is rotated from the partially lit state to the fully closed state, the slat 3 goes through the horizontal state, so that the slat 3 moved so as to be partially lit is supported by the weft thread 2a. Recover to position.

Therefore, in such a partial daylighting slat, the contact resistance by the cord guide 20 is configured to change with the rotation amount of the angle adjustment of the slat 3. In particular, the partial lighting slats were moved so as to be partially illuminated by the ascending direction movement operation of the elevating cord 5, and were moved so as to be partially illuminated by the rotation of a multi-stage slat group including the partial lighting slats. The partial lighting slats are configured to return to their original position supported by the weft 2a. That is, when the multi-stage slat group rotates from the partial lighting state, the contact resistance by the cord guide 20 is reduced in a substantially horizontal state, and the partial lighting is released.

The cord guide 20 may have a shape and material that can increase or decrease the contact resistance sufficiently for the movement and recovery operation that results in such partial lighting with respect to the slat 3 configured as the partial lighting slats. Not limited to the example shown in FIG. 3, any shape and material can be used.

The partial daylighting slats on which such a code guide 20 is installed can be set for any slats 3 among the multi-stage slats 3. The slats 3 on which the code guide 20 is installed can be changed by the user. However, in practice, although it is understood by the operation of FIG. 4B, it is meaningless to install the cord guide 20 on the slat 3 adjacent to the slat for partial lighting.

(Overall operation)
5 (a), (b), (c), and (d) show the horizontal blinds of the present embodiment when the slats 3 are horizontally (fully illuminated), reverse fully closed, partially illuminated, and fully closed, respectively. It is a side view which shows the slat movement at the time.

As shown in FIG. 5A, in the horizontal blind of the present embodiment, the support member 6 in the head box 1 winds a tilt drum 61 for suspending the ladder cord 2 so as to be movable in the vertical direction and an elevating cord 5. A take-up drum 62 that can be taken up or rewound is provided. The tilt drum 61 and the take-up drum 62 rotate as the drive shaft 7 rotates.

A multi-stage slats 3 are suspended and supported via the ladder cord 2, and a bottom rail 4 is suspended and supported at the lower end of the ladder cord 2. Then, the elevating cord 5 is suspended and supported from the head box 1, and the bottom rail 4 is attached to the lower end of the elevating cord 5.

When the drive shaft 7 is rotated in the reverse direction on the horizontal slat 3 shown in FIG. 5 (a), a multi-stage slat 3 including a partial daylighting slat on which the cord guide 20 is installed as shown in FIG. 5 (b). Is reverse fully closed.

With respect to the multi-stage slat 3 in the reverse fully closed state shown in FIG. 5 (b), the drive shaft 7 is continuously rotated in the reverse direction so as to move the elevating cord 5 in the ascending direction within the pitch interval of the multi-stage slat 3. Then, as shown in FIG. 5 (c), as the elevating cord 5 moves, the slat 3 equipped with the cord guide 20 separates from the support of the weft thread 2a and moves upward. At this time, since the slat 3 without the cord guide 20 does not move, the lower part of the slat 3 with the cord guide 20 is in a state of partial lighting. By further rotating the drive shaft 7 in the reverse direction in the state of partial lighting shown in FIG. 5 (c), the bottom rail 4 is raised and the multi-stage slats 3 are folded in order from the lowest stage slats 3. .. That is, when each slat 3 is moved in the ascending direction beyond the pitch interval, the slat for partial lighting maintains the partial lighting state until it comes into contact with the slat 3 immediately above the slat 3, and then ascends to the bottom rail 4. It is folded in order from the lower slat 3.

When the drive shaft 7 is rotated forward with respect to the multi-stage slat 3 in the partial lighting state shown in FIG. 5 (c), the partial lighting slat moved so as to be in the partial lighting through the horizontal state of the multi-stage slat 3. Is restored to the original position supported by the weft thread 2a, so that the multi-stage slats 3 are fully closed. Further, when the drive shaft 7 is continuously rotated in the forward direction, the bottom rail 4 is lowered with the multi-stage slats 3 fully closed.

The rotation directions of the slats 3 in the ascending operation and the descending operation may be configured to have the opposite relationship.

As described above, according to the horizontal blind according to the present invention, the state of partial lighting can be realized only by the presence or absence of the cord guide 20 attached to the specific slats 3, so that partial lighting can be achieved with a simpler configuration than the conventional technique. A horizontal blind can be configured. In addition, the slat position at which partial lighting is possible can be arbitrarily set or changed on the user side.

In the example shown in FIG. 4, an example in which each of the multi-stage slats 3 is placed on the weft thread 2a of each ladder code 2 has been described, but each of the multi-stage slats 3 is placed on each ladder code 2-2. It may be configured to be inserted and placed between the weft threads 2a and 2b of the book.

For example, FIG. 6A is configured as a horizontal blind according to another embodiment according to the present invention, in which each of the multi-stage slats 3 is inserted and placed between the two weft threads 2a and 2b of the respective ladder cords 2. An example is shown, and FIG. 6B schematically shows the operation at the time of partial lighting.

As shown in FIG. 6B, in the configuration in which each of the multi-stage slats 3 is inserted and placed between the two weft threads 2a and 2b of the respective ladder cords 2, the slats 3 (partial parts) equipped with the cord guide 20 are mounted. The range of movement of the daylighting slats) is restricted between the weft threads 2a and 2b, but a partial daylighting state can be realized.

Further, in the above-described example, an example in which the insertion hole 3a of the slat 3 is provided in the substantially central portion in the front-rear direction of the slat 3 has been described, but the same operation is performed when the insertion hole 3a of the slat 3 is provided in the vicinity of the end portion in the front-rear direction. ..

(Code guide for notch)
In the above-mentioned example, the example in which the cord guide 20 for realizing partial lighting is provided in the insertion hole 3a through which the elevating cord 5 is inserted is described for the slat 3, but the notch 3b for guiding the elevating cord 5 is provided in the slat 3 A slats for partial daylighting can be configured by attaching a cord guide 20a for realizing partial daylighting with a shape and material suitable for the notch 3b.

For example, FIG. 7A constitutes a partial daylighting slat as a horizontal blind according to another embodiment according to the present invention, when each of the multi-stage slat 3 is provided with a notch 3b for guiding the elevating cord 5. An example is shown in which a code guide 20a having a shape and material suitable for the notch 3b is attached to the slats 3.

The cord guide 20a can be configured as a basic structure in substantially the same manner as in FIGS. 3 (a) and 3 (b) described above, and has a pair of arm portions 22 extending from the base portion 21 in a V shape in a bifurcated shape. ing. Then, the claws (not shown) provided below the base 21 and the claws 24 provided below the respective arms 22 are assembled to the notch 3b of the slats 3 with elastic deformation of the arms 22. It is possible. The pair of arm portions 22 have a curved surface on the contact surface side with the elevating cord 5 to have a thickness in the height direction, and when assembled by elastically deforming the notch 3b, the opening area of the notch 3b. A smaller opening is formed, which causes a predetermined contact resistance with respect to the elevating cord 5 when the slats 3 are tilted.

Then, as shown in FIG. 7B, in the partial daylighting slat configured by mounting the cord guide 20a on the notch 3b of the specific slat 3, the cord guide is similar to the above-mentioned example of the cord guide 20. Partial lighting is realized when the elevating cord 5 moves in the ascending direction due to the contact resistance to the elevating cord 5 in 20a. The contact resistance is configured to change with the amount of rotation of the angle adjustment of the slats 3.

In particular, the partial lighting slats were moved so as to be partially illuminated by the ascending direction movement operation of the elevating cord 5, and were moved so as to be partially illuminated by the rotation of a multi-stage slat group including the partial lighting slats. The partial lighting slats are configured to return to their original position supported by the weft 2a. That is, when the multi-stage slat group rotates from the partial lighting state, the contact resistance by the cord guide 20a is reduced in a substantially horizontal state, and the partial lighting is released.

Also in this example, in the configuration in which three or more elevating cords 5 are hung down, it is preferable to install the cord guide 20a so that the left and right balance can be obtained. It is more preferable to install the cord guide 20a in the notch 3b.

(Slat guide that functions as a member for partial lighting)
In the above-mentioned example, the example in which the cord guide 20 or 20a for realizing partial lighting is provided in the insertion hole 3a or the notch 3b through which the elevating cord 5 is inserted has been described, but the insertion hole 3a or the notch has been described. A slat guide 20b configured to generate a predetermined contact resistance with respect to the elevating cord 5 at the upper part of the 3b can be detachably installed on the slat 3 to form a slat for partial daylighting. Such a slat guide 20b can be formed of a shape and material suitable for the slat shape, the insertion hole 3a through which the elevating cord 5 is inserted, or the notch 3b for guiding the elevating cord 5.

For example, FIG. 8A shows, as a horizontal blind of another embodiment according to the present invention, a slats for partial lighting are configured when an insertion hole 3a through which an elevating cord 5 is inserted is provided in each of the multi-stage slats 3. An example is shown in which a slat guide 20b having a shape and material suitable for the slat shape and the insertion hole 3a is attached to the slat 3.

The slat guide 20b has a base portion 21 configured in substantially the same manner as in FIGS. 3A and 3B described above as a basic structure at a substantially central portion of the main body portion 25 that engages with the upper surface of the slat 3. A cord guide 20 having a pair of arm portions 22 extending in a bifurcated shape from the base portion 21 is formed. Then, the claws 23 and 24 provided below the main body 25 allow the slats 3 to be assembled. The cord guide 20 is located above the insertion hole 3a. The pair of arm portions 22 are formed with a curved surface on the contact surface side with the elevating cord 5 to have a thickness in the height direction, and form an opening smaller than the opening area of the insertion hole 3a, whereby the slat 3 is formed. When it is tilted, it is configured to generate a predetermined contact resistance with respect to the elevating cord 5.

Then, as shown in FIG. 8B, in the partial daylighting slat configured by attaching the slat guide 20b to the specific slat 3, the slat guide 20b is substantially in the center as in the above-mentioned example of the code guide 20. Partial lighting is realized when the elevating cord 5 moves in the ascending direction due to the contact resistance of the cord guide 20 provided in the portion to the elevating cord 5. The contact resistance is configured to change with the amount of rotation of the angle adjustment of the slats 3.

In particular, the partial lighting slats were moved so as to be partially illuminated by the ascending direction movement operation of the elevating cord 5, and were moved so as to be partially illuminated by the rotation of a multi-stage slat group including the partial lighting slats. The partial lighting slats are configured to return to their original position supported by the weft 2a. That is, when the multi-stage slat group rotates from the partial lighting state, the contact resistance of the cord guide 20 provided at the substantially central portion of the slat guide 20b is reduced in the substantially horizontal state, and the partial lighting is released.

In the example shown in FIG. 8, an example in which the slat guide 20b is detachably installed from the upper part of the slat 3 and the cord guide 20 is positioned above the insertion hole 3a (or notch) has been described. The guide 20b may be detachably installed from the lower part of the slat 3, and the cord guide 20 may be positioned below the insertion hole 3a (or notch).

(Change the shape of the insertion hole)
In the above-mentioned example, the cord guide 20 (or 20a) or the slat guide 20b is attached to the slat 3 to form a slat for partial daylighting. However, the shape of the insertion hole 3a is changed to form the elevating cord 5. A slat for partial daylighting can be configured by forming it so as to generate a predetermined contact resistance with respect to. Although it is not permissible for the user to selectively change the installation of such a slats for partial daylighting, the cost can be reduced without adding parts, and partial daylighting is possible with a simpler configuration than the conventional technique. Horizontal blinds can be configured.

For example, FIG. 9A shows, as a horizontal blind of another embodiment according to the present invention, a slats for partial lighting are configured when an insertion hole 3a through which an elevating cord 5 is inserted is provided in each of the multi-stage slats 3. An example is shown in which the shape of the insertion hole 3a is changed so as to have the cut piece 31 by the cutting and bending process. The shape and size of the cut piece 31 can be arbitrarily determined according to the position and size of the insertion hole 3a and the like.

Then, as shown in FIG. 9B, in the partial lighting slats having the insertion hole 3a provided with the cut piece 31, the elevating cord 5 moves in the ascending direction due to the contact resistance to the elevating cord 5 in the insertion hole 3a. Sometimes partial lighting is realized. The contact resistance is configured to change with the amount of rotation of the angle adjustment of the slats 3.

In particular, the partial lighting slats were moved so as to be partially illuminated by the ascending direction movement operation of the elevating cord 5, and were moved so as to be partially illuminated by the rotation of a multi-stage slat group including the partial lighting slats. The partial lighting slats are configured to return to their original position supported by the weft 2a. That is, when the multi-stage slat group rotates from the partial lighting state, the contact resistance by the insertion hole 3a provided with the cut piece 31 in a substantially horizontal state is reduced, and the partial lighting is released.

As another example of changing the shape of the insertion hole, for example, FIG. 10A shows the slat 3 constituting the partial lighting slat when each of the multi-stage slat 3 is a plate-like body such as wood having a thickness. Shows an example in which the shape is changed so as to have a curved convex portion 32 that narrows the opening of the insertion hole 3a. The shape and size of the curved convex portion 32 can be arbitrarily determined according to the position and size of the insertion hole 3a and the like.

Then, as shown in FIG. 10B, in the partial lighting slats having the insertion hole 3a provided with the curved convex portion 32, the elevating cord 5 moves in the ascending direction due to the contact resistance to the elevating cord 5 in the insertion hole 3a. Sometimes partial lighting is realized. Then, also in this example, the partial lighting slats are moved so as to be partially illuminated by the ascending direction movement operation of the elevating cord 5, and the partial lighting is caused by the rotation of a multi-stage slat group including the partial lighting slats. The partial lighting slats that have moved so as to be restored to the original position supported by the weft 2a.

(Relative position change of insertion hole)
Further, the partial lighting slats can be formed by changing the relative position of the insertion hole 3a so as to generate a predetermined contact resistance with respect to the elevating cord 5. Although it is not permissible for the user to selectively change the installation of such a slats for partial daylighting, the cost can be reduced without adding parts, and partial daylighting is possible with a simpler configuration than the conventional technique. Horizontal blinds can be configured. In particular, when the elevating cord 5 is configured in a tape shape, the tape-shaped surface of the elevating cord 5 comes into line contact with the insertion hole 3a (or may be a notch) provided in the slat 3. It can be configured to create resistance.

For example, FIG. 11A shows, as a horizontal blind of another embodiment according to the present invention, a slats for partial lighting are configured when an insertion hole 3a through which an elevating cord 5 is inserted is provided in each of the multi-stage slats 3. As for the slats 3 to be used, an example in which the relative position of the insertion hole 3a is changed is shown.

Then, as shown in FIG. 11B, in the partial lighting slats configured by changing the relative position of the insertion hole 3a, the contact resistance of the insertion hole 3a to the elevating cord 5 causes the elevating cord 5 to move in the ascending direction. Partial lighting is realized when moving. Then, also in this example, the partial lighting slats are moved so as to be partially illuminated by the ascending direction movement operation of the elevating cord 5, and the partial lighting is caused by the rotation of a multi-stage slat group including the partial lighting slats. The partial lighting slats that have moved so as to be restored to the original position supported by the weft 2a.

Although the present invention has been described above with reference to examples of specific embodiments, the present invention is not limited to the examples of the above-described embodiments, and various modifications can be made without departing from the technical idea. For example, the partial lighting slats can be set for a horizontal blind that can manually raise and lower multiple stages of slats and adjust an angle, not limited to the electric type.

In particular, in the example of the above-described embodiment, the elevating device (winding drum 62) that moves the elevating cord 5 so as to allow the slat 3 to be elevated and the ladder cord 2 to be moved so that the angle of the slat 3 can be adjusted. An example has been described in which the angle adjusting device (tilt drum 61) to be operated is interlocked with the rotation of the drive shaft 7, but for example, the elevating device and the angle adjusting device are independently operated by using individual drive shafts. It can also be configured to work.

According to the present invention, it is possible to configure a horizontal blind that enables partial lighting with a simpler configuration, and more preferably, a horizontal type that allows the user to arbitrarily set or change the slat position that enables partial lighting. Since the blind can be configured, it is useful for the use of a horizontal blind that enables an operation of raising and lowering a multi-stage slats and an angle adjustment operation.
