  (3) In the accident prevention apparatus according to the present invention, the first member is an iron ring whose end can be opened, and the end has a hemispherical shape. Therefore, the ring can be easily attached to the second member.

  (4) The operation string drive type light-shielding part adjusting instrument according to the present invention is a light-shielding part composed of one curtain or a plurality of light-shielding pieces, and rotates or reverses so that the light-shielding part is shielded from light. An operation string drive type light-shielding part adjusting instrument comprising an operation shaft that switches to a released state or an intermediate state thereof, and a loop-shaped operation string that hangs down in the vertical direction for rotating the operation shaft, The chain is composed of a member that sticks to the magnet, and includes a second member that has the magnet and can be fixed to the wall.

  Therefore, the first member and the second member can be attached with a magnetic force. Thereby, the accident by the said loop-shaped operation string can be prevented.

  In this specification, “consisting of a single curtain or a plurality of light shielding pieces” means a case of a curtain such as a roll screen, a case of a plurality of light shielding pieces such as blinds and blinds. Including. “The other is composed of magnets” is a concept including the case where all or part of the other is composed of magnets. “Shading” includes not only the case where light is completely blocked, but also the case where the amount of transmitted light is reduced.

It is a figure which shows the use condition of the roll screen 1 concerning this apparatus. 3 is a plan view showing a main body 21 and a ring 31. FIG.

  FIG. 1 shows a roll screen 1 which is an operation string drive type light-shielding part adjusting device according to the present invention. The roll screen 1 includes a conventional roll screen unit 2 and an accident prevention device 10.

  The roll screen 2 includes a cloth 3 that is a light shielding portion, an operation shaft 4, and a chain 5 that is an operation string, similarly to the conventional roll screen. The cloth 3 is composed of one curtain. The operation shaft 4 switches the cloth 3 to a light shielding state, a light shielding release state, or an intermediate state thereof by rotating forward or reverse. In the present embodiment, as shown in FIG. 1, when the operation shaft 4 rotates counterclockwise, the fabric 3 is wound up to be in a light-shielding release state, and when the operation shaft 4 rotates clockwise, the fabric 3 is unwound and light-shielded. Released state. When the rotation of the operation shaft 4 is stopped halfway, the dough 3 is held in an intermediate state. The chain 5 has a loop-like string hanging in the vertical direction, and pulling one of the chains downward causes the operation shaft 4 to rotate forward or reverse by a rotation mechanism (not shown). In the present embodiment, when the chain 5 is pulled in the direction of the arrow α, the end 3a of the fabric 3 is raised, and when the chain 5 is pulled in the direction of the arrow α, the end 3a of the fabric 3 is lowered.

  The accident prevention instrument 10 will be described with reference to FIG. The accident prevention instrument 10 includes a main body 21 and a ring 31. The main body 21 has a hemispherical magnet portion 23 and a pin 25 at the tip. The ring 31 has an opening 31K and is made of a material (ferromagnetic material) that adheres to the magnet. In the present embodiment, the material of the ring 31 is made of iron, but is not limited to this.

  The usage method of the accident prevention instrument 10 is demonstrated using FIG. The pin 25 of the main body portion 21 is put on the wall to fix the main body portion 21 to the wall. The opening 31K is enlarged by twisting the ring 31, and is passed through the loop-shaped chain 5, and then the ring 31 is twisted back to close the opening 31K. As a result, the chain 5 passes through the ring 31. Since the inner diameter of the ring 31 is larger than that of the chain 5, if the ring 31 is removed in this state, the ring 31 moves to the lowermost part of the loop-shaped chain 5 by gravity. When the ring 31 is gripped and brought into contact with the main body 21, the two adhere to each other due to magnetic force. Thereby, the chain 5 is folded back at the position of the main body 21, and the tip of the loop of the chain 5 is held near the main body 21 as shown in FIG. 1. Thereby, the accident where a child etc. catches the chain 5 can be prevented.

  Since the ring 31 is only attached to the main body portion 21 with a magnet, it can be easily lowered if it is pulled during use.

  In the above embodiment, the case where the raising and lowering of the roll screen (roll curtain) is manually performed by operating the chain has been described. However, the same applies to a one-touch chain type in which the raising is performed automatically.

  Furthermore, the present invention is also applicable to a type in which the light-shielding portion is rolled up in the horizontal direction by operating the string instead of up and down.

  In the present embodiment, the case of a pin has been described, but a double-sided tape or the like may be used.

  Further, the ring 31 may be made of a magnet by using the main body 21 as a material sticking to the magnet. If a heavy magnet is used, this functions as a weight.

  In this embodiment, although the case where the main-body part 21 is fixed to a wall was demonstrated, it is applicable not only to the case where it fixes temporarily but not completely. For example, it may be in a semi-fixed state so as to be movable on the rail, and moved on the rail.

  In the present embodiment, the tip of the main body portion 21 has a hemispherical shape, but may have a shape other than a hemispherical shape.

  In the present embodiment, the case where the present invention is applied to a roll screen has been described. However, the present invention can be similarly applied to blinds, blinds, and the like in which the light shielding unit 3 is configured by a plurality of light shielding pieces. In this way, any operation string drive type light-shielding part adjusting instrument of the type that switches the light-shielding state by winding or folding the light-shielding part by rotating the operation shaft with the string is applicable.

Moreover, although the case where a string-like chain is employed has been described, any material such as metal or resin may be used. If the chain is made of a material that sticks to the magnet, the same effect can be obtained without the ring 31.
