Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention provides a ladder cord for supporting slats, which is composed of a pair of front and rear vertical cord sections and a plurality of horizontal cord sections that connect the vertical cord sections at equal intervals above and below. , by placing a plurality of slats one above the other in at least one pair, horizontally spaced apart, and placing each slat on a horizontally opposite portion of the supporting ladder cord. This relates to horizontal blinds supported horizontally at equal intervals.

[Background of the idea]

Horizontal blinds of the above type generally include, in addition to the supporting ladder cord, a lifting cord which extends vertically downward from the upper headbox through each slat and is connected to the lower plate at its lower end. The blind is opened and closed by raising and lowering the slats as a whole. However, when adjusting the light shielding with the blind closed, the slat is tilted by relatively moving up and down the pair of front and rear vertical cord portions of the support ladder cord. for example,
To block sunlight, tilt the slats at an appropriate angle to block sunlight, or to let in sunlight, tilt the slats to a horizontal position or to a position parallel to the direction of sunlight incidence. Tilt it.

In this way, horizontal blinds are characterized by being able to control the incidence of sunlight while allowing ventilation through the gaps between the slats.
Blinds also have the function of, for example, blocking the interior of a room from view from the outside. However, conventional horizontal blinds are configured so that the tilting operation of the slats is performed on all slats at the same time, so some of the slats of the blind are in a light-blocking or view-blocking state, and the other part is in an open state. You cannot do something like that. Therefore, for example, it is not possible to block the view from the outside at the lower part of the window and actively let sunlight into the room at the upper part of the window.

In order to meet these demands, a horizontal blind in which the slats are partially assembled and the spacing between the slats is partially widened was developed by Tokuko Sho.
It is disclosed in Publication No. 47-42114. As mentioned above, what is disclosed in this publication uses a slat supporting ladder cord consisting of a pair of front and rear vertical cord sections and a plurality of horizontal cord sections connecting the vertical cord sections at equal intervals above and below. In addition to supporting a plurality of slats horizontally, in addition to this supporting ladder cord, a gathering ladder cord is provided which has a horizontal cord portion located at intervals of one or more slats, and the gathering ladder cord is used as a supporting ladder cord. By increasing relative to
The slats are gathered together by the number of slats that were skipped, and the spacing between the slats in that area is widened.

With this blind, the slats can be assembled or expanded in small sections by moving the assembly ladder cord up and down with the entire blind lowered.For example, the slats are assembled in the lower half of the blind. without any
By designing the gathering ladder cord so that the slats gather only in the upper half of the blind, it is possible to construct a blind that blocks the view at the bottom of the window and allows sunlight to enter at the top of the window. can. However, in such blinds, it is necessary to design the gathering ladder cord according to individual requirements, and therefore,
Manufacturing is complicated and costs are high.

[Purpose of invention]

The purpose of the present invention is to provide a horizontal blind in which the interval between the slats of the blind is partially variable, and can be operated to partially block light or view and partially open, as desired. It is in.

Another object of the present invention is the above-mentioned Japanese Patent Publication No. 47-421143.
Supports that are commonly used in the past without requiring special parts, such as the assembly ladder cord specially designed according to individual requirements in the slat partial assembly type blind disclosed in the above publication. The object of the present invention is to provide a horizontal blind that can achieve the above-mentioned effects by using the same ladder cord as a moving ladder cord.

[Summary of the idea]

The horizontal blind according to the present invention has a ladder cord for supporting slats, which consists of a pair of front and rear vertical cord sections and a plurality of horizontal cord sections connecting the vertical cord sections at equal intervals in the upper and lower directions. A horizontal type in which a plurality of slats are supported horizontally at equal intervals vertically by arranging a pair of slats and placing each slat on the horizontally opposing horizontal cord parts of these supporting ladder cords. In the blind, a movable ladder cord having a pair of vertical cord parts and a plurality of horizontal cord parts provided at the same vertical intervals as the horizontal cord parts of the support ladder cord is used as the support ladder cord. Arranged so that it can move vertically relative to the ladder cord,
The slats that are to be moved vertically to widen the vertical spacing between the slats are placed above the horizontal cord section of the moving ladder cord, and the other slats are placed below the moving ladder cord section. This is a characteristic feature.

[Example of idea]

This will be explained below with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the horizontal blind according to the present invention, and in the figure, 1 is a head box;
2 is a plurality of slats supported horizontally at equal intervals vertically; 3 is a lower plate; 4 is a supporting ladder cord for supporting the slats; 5 is a lifting cord for raising and lowering the slats; 6 is for raising and lowering the slats. 7 indicates an operating tool for tilting the slat.

The support ladder cord 4 consists of a pair of front and rear vertical cord sections 4a and 4b, and a plurality of horizontal cord sections 4c that connect the vertical cord sections at equal intervals vertically. At least a pair of horizontally spaced
In the illustration, a pair of support ladder cords are shown; however, in larger width blinds, one or more additional support ladder cords may be provided in between). Each slat 2 is placed on horizontally opposite horizontal cord portions of these support ladder cords. In this way, a plurality of slats 2 are supported horizontally at equal intervals up and down. By operating the operating cord 6, the slat 2 is raised and lowered to open and close the blind, and by operating the operating tool 7, the vertical cord portion 4 of the supporting ladder cord 4 is moved up and down.
The tilting operation of the slat is performed by moving a and 4b relatively up and down.

In order to partially vary the vertical distance between the slats, a movable ladder cord 8 having the same structure as the supporting ladder cord 4 is provided so as to be movable relative to the supporting ladder cord 4 in the vertical direction. It will be done. The moving ladder cord 8, like the supporting ladder cord, has a pair of vertical cord sections 8a and 8b.
and the horizontal cord portion 4c of the supporting ladder cord.
It has a plurality of horizontal cord portions 8c provided at the same intervals as the vertical intervals of.

Therefore, the slat that is to be moved upward in order to partially widen the vertical distance between the slats 2 is placed above the horizontal cord portion 8c of the moving ladder cord 8, and the slat that is to be fixed is placed above the horizontal cord portion 8c. It is placed below the portion 8c. In Figure 2, 2A is the slat to be moved, 2B
indicates the slat to be fixed.

Here, when the moving ladder cord 8 is moved upward relative to the supporting ladder cord 4 by a distance corresponding to the vertical interval of the horizontal cord portion 4c, the slat 2A resting on the upper side of the horizontal cord portion 8c moves upward. However, the slat 2B located below the horizontal cord portion 8c is not moved.
As shown in FIG.
The slats 2A and 2B are moved to a position in close contact with the lower side of the slats 2A and 2B, and the distance between the slats 2A and 2B is doubled.

As described above, according to the present invention, a moving ladder cord having the same structure as the supporting ladder cord is used, and by simply changing the arrangement of the slats with respect to the horizontal cord portion of the moving ladder cord, the ladder can be moved to a desired area. It is possible to construct a section in which the spacing between the slats can be increased. However, when it is desired to widen the spacing between the slats, by operating the moving ladder cord, the spacing between the slats can be easily widened and that portion can be opened.

As mentioned above, examples of the changing states of the slats achieved by changing the arrangement of the slats with respect to the horizontal cord portion of the moving ladder cord are shown in the fourth example.
Shown in Figures A, B, C, and D. In the figure, A indicates the slat fixed part and B indicates the slat variable part. In the embodiment shown in the figures, the moving ladder cord has exactly the same structure as the supporting ladder cord, and is shown as extending vertically over the entire height of the blind from the head box to the bottom plate. In the arrangement as shown in FIG. 4A, the moving ladder cord does not need to extend over the entire height of the blind, but only needs to extend as far as the height of the upper variable part B.

[Effect of idea]

The present invention achieves the following effects.

(1) A blind that can be partially opened can be constructed without requiring any special parts or manufacturing means.

(2) Since the usage status of the blind can be changed according to the wishes of the blind user, the range of usage can be improved.
