Description

  The present invention relates to an operation cord terminal that hangs down from a cord terminal that joins a plurality of lifting cord terminals that are pulled out from a head box of a solar shading device.

  In a solar shading device such as a venetian blind or a roman shade, a plurality of lifting cords that open and close the solar shading material are pulled out from the head box via cord stoppers, and their terminals are bound to a cord terminal. The cord terminal is used as a grip for opening and closing the solar shading device. However, when this cord terminal is at a high position, it is inconvenient to operate, and therefore an operation cord hanging from the cord terminal is operated. When the cord terminal is in a low position, if the terminal of the operation cord is left unattended, it hangs down unsightly. Usually, as described in JP-A-2002-339670, the terminal of the operation cord has a stopper attached to the weight bar. It is fixed via.

Infants play behind or behind the solar shading material of the solar shading device, so when the terminal of the operation cord is fastened to the weight bar via the fastener, when the infant plays with the sun shading material, There is a risk that the operation cord may hang on the infant's neck, causing the infant's neck to be choked and cause a major safety accident.
JP 2002-339670 A

  The present invention has been made to solve this problem, and the problem is to prevent a safety accident that the operation cord hanging from the elevating cord terminal of the solar shading device squeezes the infant's neck. It is.

  In order to achieve the above object, the means employed by the present invention can release the terminal of the operation cord hanging from the cord terminal that binds the terminals of the plurality of lifting cords pulled out from the head box of the solar shading device with the power of the infant It attaches to the back surface of a solar radiation shielding material through a suitable coupling member.

  According to the present invention, the coupling member for fixing the operation code terminal of the solar shading device to the back surface of the solar shading member by the above means releases the coupling immediately by the force of the infant, and the terminal of the operation code is released from the back surface of the solar shading member. Since it comes off and becomes a free end, even if the operation coder is hung on the infant's neck, there is no possibility that the infant's neck will be squeezed.

  The connecting member for fixing the operation cord terminal of the present invention to the back surface of the solar shading member includes, in terms of cost, a cloth-like joint piece such as Velcro (registered trademark), or a joint shaft portion and a cylindrical joint bearing portion. A snap joint that is elastically moved in and out is preferable. When the coupling member is a needle cloth-like joining piece, the operation cord side half is attached to the operation cord terminal, and the coupling member half on the solar shading material side is attached to the back surface of the solar shading material. When there is no crease in the solar shading material, a long needle cloth-like joining piece is attached, but when there is a crease, the divided cloth attachment piece is attached while avoiding the crease. When the coupling member is a snap joint, the joint bearing portion is attached to the operation cord terminal, and the joint shaft portion is integrally formed with a cord insertion ring or a cord adjuster attached to the back surface of the solar radiation shielding material.

  The present invention will be described based on embodiments shown in the drawings. 1 is a side view of a roman shade equipped with an operation code terminal according to an embodiment of the present invention, FIG. 2 is an enlarged perspective view of the operation code terminal, and FIGS. 3 and 4 are rear views of essential parts of the roman shade according to the embodiment of the present invention. It is.

  As shown in FIGS. 1 and 2, one end of the lifting / lowering cord 2 of the roman shade 1 exits from the head box 3 and is attached to the cord terminal 4, and the other end is provided with a cord insertion ring 6 attached to the back surface of the screen 5. It penetrates and hangs down and is fixed to the cord adjuster 7. The distal end of the operation cord 8 is attached to the cord terminal 4 and the end is attached to the cloth-like joint piece 9.

  As shown in FIGS. 1 and 3, a long cloth-like joining piece 10 extending from the head box 3 to the weight bar 13 is bonded to the operation side edge of the back surface of the screen 5. The cloth-like joining piece 9 attached to the operation cord terminal is pressed against the cloth-like joining piece 10 to be coupled.

  As shown in FIG. 4, when the screen 5 forms the fold line 14, the cloth-like joining piece 10 is divided into short pieces and attached to the back surface so as not to straddle the fold line. The needle cloth-like joining piece 9 attached to the end of the operation cord 8 is pressed and joined to any one of the divided needle cloth-like joining pieces 10.

  When the operation cord 8 is pulled to raise the screen 5, no tension acts on the cloth-like joint piece 9. However, when the infant is playing with the screen 5 and the operation cord 8 is entangled with the infant, the pulling force of the infant acts on the cloth-like joining piece 9. As a result, the needle cord-like joining piece 9 on the operation cord terminal side is immediately peeled off from the needle cloth-like joining piece 10 on the back side of the screen, and the terminal of the manipulation cord 8 becomes a free end. There is no risk of tightening infants.

  Next, another embodiment shown in the drawings will be described. FIG. 5 is a main part rear view of a roman shade provided with an operation code terminal according to another embodiment, FIG. 6 is an enlarged side view of an operation code terminal and a code adjuster, and FIG. 7 is an enlarged elevation view of a code insertion ring.

  As shown in FIG. 5, one end of the lifting / lowering cord 2a of the Roman shade 1a exits from the head box 3a and is connected to the cord terminal 4a, and the other end passes through the cord insertion ring 6a attached to the back surface of the screen 5a. To the cord adjuster 7a. The end of the operation cord 8a hanging from the cord terminal 4a is coupled to the cord adjuster 7a via the joint bearing portion 11.

  As shown in FIG. 6, the end of the operation cord 8a is bound to the joint bearing portion 11 via a knot, and the joint bearing portion 11 is a snap integrally formed with the lower end portion of the cord adjuster 7 as indicated by an arrow. The joint shaft portion 12 is fitted and coupled. As shown in FIG. 7, since the joint shaft portion 12 is also integrally formed with the lower end portion of the cord insertion ring 6, the joint bearing portion 11 is fitted to the lower end portion of the cord insertion ring 6 as indicated by an arrow. It is also possible to combine them.

  The joint bearing portion 11 has a protrusion 15 on the inner peripheral surface, and the joint shaft portion 12 includes a tapered truncated truncated cone-shaped head 16 having a bottom diameter larger than the inner diameter of the protrusion 15 on the distal end side. When the joint bearing portion 11 is pushed slightly strongly into the joint shaft portion 12, the projection 15 elastically climbs over the head portion 16, and both are immediately coupled to form a snap joint.

  When the joint bearing portion 11 of the coupled snap joint is pulled out slightly strongly, the protrusion 15 elastically climbs over the head 16 and the snap joint is separated immediately. Therefore, when the operation cord 8a is applied to the infant, the snap joint is immediately separated by the infant's force, and the terminal of the operation cord 8a becomes a free end, so there is no possibility that the operation code 8a applied to the infant will tighten the infant.

The side view of a roman shade provided with the operation code terminal of the embodiment of the present invention, An enlarged perspective view of the operation cord terminal, Partial rear view of the roman shade where the screen does not form a crease, Partial back view of the roman shade where the screen forms a crease, The principal part back view of a roman shade provided with the operation code terminal of another example, Enlarged side view of operation cord terminal and cord adjuster, Enlarged elevation of the cord insertion ring,
