Description

  The present invention relates to a blind.

  A conventional horizontal blind is disclosed in Japanese Utility Model Publication No. 7-35118 (Patent Document 1). In this document, the lower end of the ladder cord is introduced into the cord holder from both sides of the bottom rail and both lower end portions are connected, and then the cap is fitted into the opening of the cord holder to connect the ladder cord to the bottom rail. It is disclosed.

  According to this, since the length of the ladder cord can be adjusted without removing the cord holder from the bottom rail, the assembling work of the blind can be shortened.

No. 7-35118

  However, the ladder cord is connected to the bottom rail by connecting and fixing both lower ends of the ladder cord with fastener clips and fitting them into one cord holder, and connecting the cord holder to the bottom rail. For this reason, both the lower end portions of the ladder cord and the position adjustment can only be performed at the same time, and there is a problem that the lower end portions of the ladder cord cannot be connected and the position adjustment cannot be performed separately. In addition, such a problem may have the same problem when not only the ladder cord but also two or more members (such as a cord and a shielding material) are connected to one bar material such as a bottom rail and an intermediate bar. is there.

  Therefore, the present invention has been made in view of such problems, and the object of the present invention is to connect and adjust the position of each member when two or more members are connected to one bar member. It is to provide blinds that can be performed separately.

  In order to solve the above-described problem, according to a first aspect of the present invention, a ladder cord having front and rear longitudinal cords and supporting a plurality of slats in an aligned state is connected to the lower ends of the front and rear longitudinal cords. And a connecting member for connecting the lower end of the front and rear vertical cords and the bar member, and the connecting member connects the lower ends of the front and rear vertical cords separately to the bar member. A blind is provided.

  According to such a configuration, the lower ends of the front and rear vertical cords are separately connected to the bar material by the connecting member, so that the lower ends of the front and rear vertical cords can be connected and adjusted separately. Furthermore, regardless of the shape of the bar material, it is easy to connect the front and rear vertical cords to the bar material.

The present invention can be applied in various ways. The following application examples can be appropriately combined.
For example, the bar member is formed with an insertion portion (for example, a recess, a hole, a notch, or the like) through which the front and rear vertical cords are inserted, and the connecting member has the front and rear vertical cords inserted into the insertion portion. You may make it connect with the said bar material in the state penetrated by. By passing the front and rear vertical cords through the insertion portion formed in the bar material, it is easy to prevent lateral shift and adjust the alignment of the front and rear vertical cords.

  Moreover, you may make it the said bar material and the said connection member engage in either of 1 or 2 or more engagement positions. Since the bar member and the connecting member can be connected by being engaged at the engaging position, they can be easily connected. In addition, the length of the front and rear longitudinal cords can be adjusted by changing the engagement position between the bar member and the connecting member at one or two or more engagement positions.

  Further, the connecting member may be configured in a substantially U shape, and the connecting member may be connected so as to sandwich the bar material. By fixing the bar member so as to be sandwiched by the substantially U-shaped connecting member, the connecting member can be prevented from being easily detached from the bar member. Moreover, if it fixes so that it may pinch | interpose with a substantially U-shaped connection member, if there is a flat plate part in a bar material, it can fix easily to that location.

  Further, the front and rear vertical cords may be provided with a plurality of enormous portions in the length direction, and any of the enormous portions may be locked to the bar material or the connecting member. By providing enormous portions such as fastener clips on the front and rear vertical cords, the front and rear vertical cords can be prevented from easily coming off because the enormous portions are locked to the bar material or the connecting member. In addition, for example, the length of the front and rear longitudinal cords can be adjusted by moving the position of the enormous part or selecting the enormous part to be locked in accordance with the use state from a plurality of enormous parts and engaging the connecting member. Can be made possible.

  Moreover, the raising / lowering cord which raises / lowers the said slat is provided, and the said raising / lowering cord may be connected with the said bar material by the said connection member with either one of the said front and back longitudinal cords. Since the elevating cord for raising and lowering the slats is connected to the bar member together with the front and rear vertical cords, the elevating cord can be fixed to the bar member without adding parts.

  The bar member may be substantially L-shaped, and lower ends of the front and rear vertical cords may be connected to the bar member at different height positions. By making the bar material substantially L-shaped, for example, by arranging one surface of the bar material in parallel with the slat and the other surface orthogonal to the slat, the slat disposed below the bar material. When the is rotated, the other surface can close the gap between the one surface and the slat. Therefore, the shielding property can be improved.

  In order to solve the above-described problems, according to a second aspect of the present invention, a shielding material, a cord that hangs along the shielding material (for example, an elevating cord, a pitch cord, etc.), the shielding material, and the cord A bar member to which a lower end is connected; and a connecting member for connecting the lower end of the cord and the bar member, and an engaging portion is formed on the connecting member so as to be sandwiched between the bar members. A blind is provided in which the connecting member and the bar member are connected by engaging the engaging portion with an engaged portion formed on the bar member.

  According to this configuration, since the lower end of the cord is connected to the bar material to which the shielding material is connected by the connecting member, the shielding material and the cord are separately connected to the bar material. Therefore, the position adjustment of the shielding material and the lower end of the cord can be performed separately. Furthermore, an engagement part such as a convex part formed on the connecting member is engaged with the engaged part of the bar material, so that a cord that hangs down along the shielding material regardless of the shape of the bar material. It becomes easy to connect to the bar material by the connecting member. Moreover, if a connection member is connected so that a bar material may be inserted | pinched, if a bar member has a flat plate part, it can connect easily to the location.

  ADVANTAGE OF THE INVENTION According to this invention, when connecting two or more members which comprise a blind to one bar material, it is possible to provide the blind which can perform position adjustment of each member separately, respectively. Other effects of the present invention will also be described in a mode for carrying out the invention described later.
