Description

[Detailed description of the invention] Purpose of the invention (industrial application field) This invention consists of a connecting cord that connects the first slat hanger and the next slat hanger in a vertical blind, and a slat hanger at the rearmost end. The present invention relates to a length adjustment mechanism that can freely adjust the length of at least one of the connecting cords connecting a slat hanger and a slat hanger in front of it.

(Prior Art) Conventionally, in vertical blinds, a large number of slats are suspended and supported via slat hangers from a runner that moves within a hanger rail, and each slat hanger rotates in a horizontal direction with respect to the runner. It can be suspended and supported, and both ends are connected by a connecting cord. When the first guide hanger is pulled out along the hanger rail, subsequent slat hangers are pulled out one after another at regular intervals by the connecting cord, and the first guide hanger is rotated with the slats pulled out. If you let me,
Similarly, each slat is rotated in the same phase by the connecting cord to adjust the angle of the slat.

(Problem to be solved by the invention) However, in the vertical blind having the above-described structure, in order to rotate the angles of each slat in the same phase, the connecting cord that connects each slat is always under tension between all slats. It is necessary to arrange it so that. Therefore, if the length of the hanger rail is shorter than the predetermined length of the vertical blind due to the size of the window to which the vertical blind is installed, the connecting cord may become loose between the slats and the slats may become loose. There is a problem that the two do not rotate in the same phase.

Structure of the invention (means for solving the problem) In order to solve the above-mentioned problem, the present invention has a connecting cord that connects the first slat hanger and the next slat hanger, and a connecting cord that connects the slat hanger at the end. A cylindrical member having an insertion hole through which the connecting cord is inserted is attached to at least one of the connecting cords connecting the hanger and the slat hanger in front of the hanger. A method is adopted in which a fixing member is removably attached to clamp the connecting cord in cooperation with other members.

(Function) When the fixing member is attached to the connecting cord placed in the insertion hole of the cylindrical member, the cylindrical member and the fixing member work together to clamp the connecting cord, and this part connects the cylindrical member. and the connecting code are fixed. Therefore,
By changing the fixing position of the connecting cord arranged on the cylindrical member, the distance between the first slat hanger and the next slat hanger, or the distance between the last slat hanger and the previous slat hanger can be changed. The distance can be adjusted arbitrarily.

(Example) The first example that embodies this idea will be described below.
This will be explained with reference to FIGS.

First, to explain the overall outline of the vertical blind 1 of this embodiment, as shown in FIG. The slats 4 are each suspended and supported through them.
The slat hangers 3a and 3b are rotatably supported in the horizontal direction by a runner 5 moving within the hanger rail 2, and both ends are connected by a connecting cord 6, respectively. An operating rod 7 for pulling out and folding the slats 4 or adjusting the angle of each slat 4 is attached to the slat hanger 3a at the tip. When the operating rod 7 is used to pull out the slat hanger 3a at the tip along the hanger rail 2, the following slat hangers 3b are sequentially pulled out at regular intervals by the connecting cord 6. When the slat hanger 3a is rotated, each slat hanger 3b is rotated by the connecting cord 6, and the slat hanger 3a is rotated.
The angles are adjusted in the same phase.

Next, to explain the slat support structure of the slat hangers 3a and 3b, as shown in FIGS. A hanging rod 8 for downward support is protruded, and a locking recess 9 that opens downward is provided at the tip of the hanging rod 8.
is formed. Further, locking holes 10 are provided in the slat hangers 3a and 3b above the locking recess 10.
is penetrated.

Connect the tips of the hanging rods 8 to the slat hangers 3a and 3b.
A connecting tool 11 for connecting to a device has a generally U-shape as a whole, and a locking protrusion 12 that engages with the locking hole 10 is formed on the inner surface of the upper end thereof, and a locking protrusion 12 that engages with the locking hole 10 is formed on the inner surface of the lower end thereof. A locking protrusion 13 that engages with the locking recess 9 is formed. Therefore, in order to suspend and support the slat 4 from the above-mentioned slat hangers 3a and 3b, the hanging rod 8 is inserted into the bent part 14 formed at the upper end of the slat 4, and in this state, the tip of the hanging rod 8 is When the connector 11 is fitted from below and the locking protrusion 12 is engaged with the locking hole 10, the locking protrusion 13 engages with the locking recess 9 and the connector 11 is inserted into the slat. The slats 4 are fixed to the hangers 3a and 3b, and as a result, the slats 4 are suspended and supported by the slat hangers 3 while being prevented from falling off by the connectors 11.

Next, to explain the installation structure of the connecting cord 6 that connects each slat hanger 3a, 3b, as shown in FIG.
A position regulating member 22 formed in a semi-cylindrical shape is integrally formed with the slat hanger 3a at both ends of the upper part thereof, and a flange 22a is formed protruding from a part thereof. An end hook 15 made of synthetic resin to which the vicinity of the tip of the connecting cord 6 is fixed is rotatable by a fixing pin 16 (the first
(indicated by the dashed line in the figure). This end hook 15 has a cylindrical hook main body 17 having an insertion hole 17a through which the connecting cord 6 is inserted.
, a plate-shaped projecting piece 18 that projects outward from the hook main body 17 and into which the fixing pin 16 is inserted, and a cap 19 as a fixing member that can be inserted into the insertion hole 17a. ing. The cap 19 also includes a cylindrical pressing portion 20 formed at the tip thereof, which is larger than the diameter of the insertion hole 17a minus the diameter of the connecting cord 6, and smaller than the diameter of the insertion hole 17a. The flange portion 21 is made up of a flange portion 21.

Therefore, if the connecting cord 6 is inserted into the insertion hole 17a and the pressing part 20 of the cap 19 is inserted from the distal end side of the connecting cord 6, the pressing part 20 and the inner wall of the insertion hole 17a will be connected to each other as shown in FIG. The connecting cord 6 is secured to the end hook 15 by being sandwiched between the connecting cords 6 and 6 in a small gap.

Furthermore, the flange 22 of the position regulating member 22
A locking wall 22b is formed at the lower part of a, and the protruding piece 18 of the end hook 15 is attached to the locking wall 22b.
The rotation angle of the end hook 15 is regulated by this contact.

Further, as shown in FIG. 4, synthetic resin hooks 23 into which the connecting cords 6 are inserted and fixed are attached to both upper ends of the slat hangers 3b other than the first slat hanger 3a by means of fixing pins 16. Rotatably supported.

Now, the vertical blind 1 configured as described above is attached to the hanger rail 2, and the operating rod 7
When the first slat hanger 3a is pulled out, the following slat hangers 3b are successively pulled out at regular intervals by the connecting cord 6.

At this time, the length of the hanger rail 2 may be longer than that of the vertical blind 1 due to the size of the installation window.
If the length is shorter than the predetermined length of each slat hanger 3a, 3b, as shown by the dotted line in FIG.
The connecting cord 6 that connects the slat hangers 3a, 3b cannot be tensioned and becomes loose at some point, making it impossible to rotate the slat hangers 3a, 3b in the same phase.

However, in the vertical blind 1 of this embodiment, the end hook 15 of the first slat hanger 3a is provided with an insertion hole 17a through which the connection cord 6 can be inserted, and the connection is made by being inserted into the insertion hole 17a. Since the cap 19 that clamps and fixes the cord 6 to the end hook 15 is removably attached, by removing this cap 19 and pulling the connecting cord 6, the first slat hanger 3a and the next slat hanger can be connected. 3b, and the connecting cord 6 between the second and subsequent slat hangers 3b can be tightened. Then, by inserting the cap 19 into the insertion hole 17a again and fixing the connecting cord 6 to the end hook 15, the slat hangers 3a and 3b can be fixed in a tensioned state.

Therefore, even if the length of the hanger rail 2 to which the vertical blind 1 is attached is shorter than the predetermined length of the vertical blind 1, the connecting cord 6 between the slat hangers 3a and 3b is always connected to the vertical blind 1. Since the slats 4 can be brought into tension, the angles of each slat 4 can be reliably adjusted in the same phase.

Further, since the simple work of removing the cap 19 and pulling the connecting cord 6 is sufficient, it can be easily carried out at the installation site.

Furthermore, since the part where the distance between each slat 4 is changed is between the first slat hanger 3a and the next slat hanger 3b, it is possible to minimize the deterioration of the appearance. .

In addition, since the cap 19 is provided with the flange 21,
The connecting cord 6 is clamped not only on the inner wall of the insertion hole 17a but also between the open end of the end hook 15 and the flange 21, so that the end hook 1 is held even more firmly.
5 and the connecting cord 6 are fixed.

Furthermore, if the length of the connecting cord 6 protruding from the outside of the end hook 15 is made longer, it can be used even when the length of the hanger rail 2 is longer than that of the vertical blind 1.

(Second Embodiment) Next, a second embodiment of this invention will be described with reference to FIGS. 6 to 8.

In this embodiment, a pair of clamping pieces 32 having an insertion hole 32a communicating with the insertion hole 17a is provided on the hook main body 17 of the end hook 15, and a claw portion securely fixes the connecting cord 6 to the inner wall of the insertion hole 32a. This embodiment differs from the first embodiment only in that 31 is provided.

More specifically, a pair of right and left clamping pieces 32 are integrally formed at the base end of the hook body 17, and the insertion hole 17 is provided inside the gripping pieces 32.
An insertion hole 32a communicating with a is formed. A pressed portion 33 having a substantially spherical outer periphery is formed at the tip of the clamping piece 32, and two claw portions 31 are formed at each portion of the inner wall of the insertion hole 32a facing the pressed portion 33. ing. A fixing member 35 having a through hole 35a is removably fitted on the outer periphery of the holding piece 32, and an anti-slip groove 35b is provided on the outer periphery of the fixing member 35.
is formed. Further, the diameter of the pressed portion 33 of the clamping piece 32 is formed larger than the diameter of the through hole 35a, so that when the fixing member 35 is fitted, the clamping pieces 32 are deformed in the direction of approaching each other. It's getting old.

Therefore, this embodiment also has the through holes 17a, 3.
When the connecting cord 6 is inserted into the inner wall of the clamping piece 32 and the fixing member 35 is fitted to the outer periphery of the clamping piece 32, the connecting cord 6 is inserted into the claw part 31 formed on the inner wall of the clamping piece 32, as shown in FIG. By being pinched by the hook, the claw portion 31 bites into the connecting cord 6 and the end hook 1
5 and the connecting cord 6 are firmly fixed.

Therefore, this embodiment has the same effect as the first embodiment, and since the fixing member 35 is placed between the slat hanger 3a at the tip and the slat hanger 3b next to it, it can be easily removed from the hook main body 17. Even if the fixing member 35 is placed on the connecting cord 8, the fixing member 35 will not be accidentally lost.

(Third Example) Next, a third example embodying this idea will be described as a ninth example.
This will be explained with reference to FIGS.

This embodiment differs from the previous embodiments only in that a cylindrical member 36 is attached to approximately the center of the connecting cord 6 that connects the first slat hanger 3a and the next slat hanger 3b.

More specifically, the insertion hole 36 of the cylindrical member 36
The connecting cord 6 is inserted into the hole a in a U-shaped folded state. A pressing portion 38 inserted into the insertion hole 36a is provided in the folded portion of the connecting cord 6;
A cap 39 is attached which includes a flange portion 37 having two guide grooves 37a through which the connecting cord 6 of the folded portion passes. Further, the pressing portion 38 is formed so that the distance between its outer circumferential surface and the inner wall of the insertion hole 36a is smaller than the diameter of the connecting cord 6, and the tip of the pressing portion 38 is shaped so that it can be easily inserted into the insertion hole 36a. It is formed into a tapered shape that becomes smaller in diameter.

Therefore, in this embodiment, if the pressing part 38 of the cap part 39 is also inserted into the insertion hole 36a of the cylindrical member 36, the connecting cord 6 will be sandwiched between the inner wall of the insertion hole 36a and the outer circumference of the cylindrical member 36. By being worn, the position of the connecting cord 6 is fixed, and the length of the connecting cord 6 can be shortened by the length of the folded portion disposed on the lower surface side of the cap portion 39.

Therefore, in this embodiment as well, the lengths of the first slat hanger 3a and the next slat hanger 3b of the vertical blind 1 can be arbitrarily adjusted to make each slat 4
The angle can be adjusted in the same phase, and
It can be attached later to a conventionally used vertical blind 1.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and can be modified and embodied as shown below, for example.

(1) In the first and third embodiments, the insertion hole 17
Anti-slip unevenness may be provided on the inner walls of a and 36a and on the outer peripheries of pressing parts 20 and 38. In this way, the connecting cord 6 can be firmly fixed to the end hook 15 and the cylindrical member 36.

(2) In each of the above embodiments, the end hook 15 and other hooks 23 are attached to each slat hanger 3.
Although the present embodiment is of the type that rotates relative to the end hook, this is not necessarily necessary and the end hook 15 and other hooks 23 may be of a type that does not rotate.

(3) In each of the above embodiments, the first slat hanger 3
The connecting cord 6 connects the slat hanger 3b and the next slat hanger 3b.
It may be embodied in the connecting cord 6 that connects the rearmost slat hanger 3c shown in the figure and the slat hanger 3b in front of it, or it may be embodied in both of these.

Effects of the invention As detailed above, according to the invention, there is a connecting cord that connects the first slat hanger and the next slat hanger, and a connecting cord that connects the last slat hanger and the slat hanger in front of it. Since it is possible to arbitrarily adjust the length of at least one of the connecting cords that connect the At the time of installation, the connecting cord can be easily tensioned, and therefore the angles of each slat can always be adjusted in the same phase, which is an excellent effect.
