Description

The present invention relates to a slat fixing device for blinds.

A conventional blind slat fixing device is disclosed in Japanese Patent Laying-Open No. 2016-14276 (Patent Document 1). The blind slat fixing device disclosed in Patent Document 1 has a flat contact surface for closely contacting the lower surface of the wooden slat with the middle cord, and is provided on both sides of the contact surface to lock each long side of the wooden slat. a first claw and a second claw that engage with each other; and a middle-stage cord insertion part provided between the first claw and the second claw and through which the middle-stage cord is inserted. A pair of slits are formed in the contact surface near the first claw and the second claw so that the contact surface has flexibility in the direction perpendicular to the lower surface of the wooden slat and in the width direction of the wooden slat. be. The contact surface between the slit and the first and second claws is a fixing portion that clamps and fixes the intermediate cord between the first and second claws. The contact surface between the pair of slits is an elastic portion that presses the middle cord against the lower surface of the wooden slat.

According to such a configuration, the slat fixing device for the blind has flexibility due to the slits in the close-fitting surface. It can be absorbed by the deformation of the contact surface. In addition, since the contact surface has the fixed portion and the elastic portion, the intermediate cord can be firmly held by being pinched by the fixed portion and pressed by the elastic portion. Therefore, the blind slat fixing device has the advantage that it can always be attached to the wooden slat in an optimal state.

JP 2016-14276 A

By the way, in the conventional blind slat fixing device as described above, since the width of the middle cord is generally formed longer than the width of the slat, the ladder cord is outside the fixing portion of the slat fixing device. There is a redundant part of the middle code connected to the vertical code. Therefore, when the front and rear vertical cords move relative to each other and the middle cord tilts, the surplus portion becomes slack and the middle cord cannot immediately follow the movement of the vertical cord. Therefore, a delay occurs in the tilting motion of the slats, so there is a problem that sufficient shielding performance cannot be obtained compared to the amount of movement of the longitudinal cords.

SUMMARY OF THE INVENTION The present invention has been made in view of such problems. To provide a slat fixing device for a blind capable of obtaining sufficient shielding property without causing a crack.

In order to solve the above problems, according to a first aspect of the present invention, there is provided a blind slat fixing device attached to a slat for locking a middle cord of a ladder cord to the slat, wherein the slat is A first locking portion (middle cord locking portion) for locking the supported middle cord, and a second locking portion (vertical cord locking portion) for locking the vertical cord of the ladder cord. There is provided a slat fixing device for a blind characterized by:

According to such a configuration, since the second locking portion locks the vertical cord of the ladder cord, the slat fixing device moves together with the vertical cord. Therefore, the second engaging portion can efficiently transmit the tilting motion of the ladder cord to the slat, and the slat can follow the rotation of the ladder cord when tilting.

According to a second aspect of the present invention, there is provided a blind slat fixing device attached to a slat for locking a middle cord of ladder cords to the slat, wherein the middle cord is formed from a plurality of horizontal cords. At least one horizontal cord is arranged on one of the upper and lower surfaces of the slat, and the remaining horizontal cords (all other horizontal cords) are arranged on the other surface of the slat. a first locking portion for locking the horizontal cord arranged on one surface of the slat; a second locking portion for locking the vertical cord of the ladder cord; and the other surface of the slat. A slat fixing device for a blind, characterized by comprising a third locking portion that locks the horizontal cord arranged in the .

According to such a configuration, the first locking portion locks the horizontal cord on one surface of the slat, and the third locking portion locks the horizontal cord on the other surface of the slat, thereby locking the slat. In the specifications where the upper and lower horizontal cords are passed through (intermediate step), the upper and lower horizontal cords are locked to the slats. Therefore, in addition to the effect of the first aspect, since the slats and the upper and lower horizontal cords rotate integrally when the ladder cord is tilted, the shielding performance of the slats is improved.

Various applications are possible for the present invention. For example, the second locking portion and the third locking portion may be configured by a common locking piece. The structure of the slat fixing device can be simplified by configuring the second locking portion and the third locking portion with a common locking piece. In addition, since the slat fixing device locks the vicinity of the connecting portion between the vertical cord and the intermediate cord, the slat rotation followability when the ladder cord is tilted is further improved.

Moreover, you may make it the said 2nd latching|locking part latch the said vertical cord along a hanging direction. The vertical cord of the ladder cord is guided in a straight line along the hanging direction even though it is locked by the second locking portion, and the route of the vertical cord does not change, thus preventing uneven vertical slat spacing. can.

Further, a supporting wall with which a side edge of the slat abuts, and a fixing piece projecting from the supporting wall toward the slat and fixing the slat may be further provided. Since the slat can be fixed by the fixing piece, the slat fixing device can be fixed to the slat without wobbling.

Further, an insertion portion through which the vertical cord of the ladder cord is inserted may be provided, and the second locking portion may lock the vertical cord inserted through the insertion portion. The vertical cord can be locked to the second locking portion simply by inserting the vertical cord through the insertion portion.

According to the blind slat fixing device of the present invention, when the longitudinal cords in front of and behind the ladder cords move relative to each other and the middle cord tilts, the tilting motion of the slat does not delay and sufficient shielding properties are obtained. Other effects of the present invention will also be described in the mode for carrying out the invention, which will be described later.
