Abstract

<P>PROBLEM TO BE SOLVED: To provide a structure which self-releases a tuft holder securely when a curtain is drawn forcibly even if a tassel cord of the curtain is hooked at any angle and prevents the tassel holder from being caught by an L-shaped bottom part of a hook member even if the tassel holder is hooked in any way. <P>SOLUTION: A tassel holder fixture 8 includes an installing fixture 10 which is formed with a back section 10b of a tassel holder and with a concave sphere seat 10d on a back surface hollow section 10c, a sphere member 12 having a convex surface 12a which rotatably slides while being pressed against the concave sphere surface 10d by a resilient means 13 at all times, and a hook member 11 fixed securely on the sphere member 12 and having an arm 11b branched from a hook head 11a for hooking tassel cords 5 and 6 of the curtain. The resilient member 13 is energized while motion in the rotational direction is controlled by a spring supporting member 14 installed on the back surface of the sphere member 12 and the installing fixture 10. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

   The present invention relates to a tufted metal fitting capable of self-releasing tufting when an electric curtain is used and when the curtain is forcibly closed.

   Recently, electric curtains have been used in nursing homes and hospitals. This is because the curtain can be freely opened and closed by a remote control operation (remote operation) even when bedridden. However, there are cases where a nurse or an attendant there may open the curtain by hand, or the curtain may be fixed to the tufted bracket by the bunch. In this way, the electric curtain remote controller is operated in a state where the curtain is held on the tuft. If this happens frequently, the electric curtain or the curtain is damaged.

Thus, a tufted metal fitting has been devised in which the tuft of the curtain is self-released when the electric curtain remote controller is operated in a state where the curtain is held on the tuft, and does not hinder the opening and closing of the curtain.
However, these hook metal fittings are not fully satisfactory and have two drawbacks.
One is that the hook member of the tufted metal fitting only rotates in the clockwise and counterclockwise directions when viewed from the mounting surface, so that it may not be released depending on how the tufted cord is hooked. For example, it is not released when pulled perpendicularly to the mounting surface.
Second, if the tuft is unlucky and is hanging on the bottom of the L-shaped hooking member, the hooking member cannot be rotated even if the curtain is pulled, and the hook is completely locked.

Therefore, especially in the case of nursing homes and hospitals, many healthy persons, persons with disabilities, and the elderly are able to handle the electric curtain, operate the remote control, operate the remote control, and secure the self-release hook metal fittings. It is requested.
Further, when closing the curtain even in a general home, it is possible to close the bundled curtain by pulling the curtain slightly without removing the tuft, and convenience is increased.

  To solve this problem, regardless of the angle at which the curtain tufts are hooked, when the curtain is forcibly pulled, the tufts are surely released and how Even if the string is hung, it is structured so that the tufted string does not cover the bottom of the L-shaped hooking member.

A mounting bracket 10 that is directly attached to a pillar or the like, forms a tufted back portion 10b, and has a concave spherical seat 10d formed in a back cavity portion 10c, is constantly pressed against the concave spherical surface 10d by an elastic means 13. A spherical member 12 having a convex surface 12a that freely slides is provided. The spherical member 12 is securely fixed to the spherical member 12, and has a hooking head 11a and a branched arm 11b for hooking the tufts 5 and 6 of the curtain. A hook member 11 is provided, and the elastic member 13 is urged at both ends by a spring support member 14 disposed on the back surface of the spherical member 12 and the mounting bracket 10 so as to restrict movement in the rotational direction. A tufted metal fitting 8 is provided.

As described above, when attaching the fixed side 6 of the tuft to the tuft fitting 8 of the curtain for the electric curtain, the fixed side string of the tuft while pulling the hooking member 11 forward and rotating left or right. 6 is attached to the L-shaped bottom portion of the hooking member 11 and then the hooking member 11 is once opened, the arm 11b closes the fixed side string, and it cannot be removed even if it is pulled in any way.
Further, when the curtain 3 is bundled with the tuft 4 and the tufted string 5 is hung on the hooking head 11a of the hooking member 11, the tufted string 5 does not fall to the bottom of the hooking member 11 and is caught by a relatively shallow portion above the arm 11b. It will be. In addition, the hook member 11 can quickly self-release the tuft 5 by inclining with respect to a tensile load from any direction when the curtain is pulled.

  When operating the electric curtain with the remote control, use the main hook metal fittings as a set, and ensure safety against remote control operation when the curtain is unintentionally bundled with tufts. Furthermore, this self-releasing tufting bracket is convenient when the user wants to unlock the tufting by pulling a normal bundled curtain slightly.

  FIG. 1 shows the overall configuration of a situation in which an electric curtain and a hook metal fitting of the present invention are attached. The electric curtain 1 has a plurality of runners 2. The upper end of the curtain 3 is fixed to the runner 2 with a clip or the like, and the curtain 3 is opened and closed by a remote control operation. FIG. 1 shows a state in which the curtain 3 is bundled by a hook metal fitting 8 attached to a pillar 7 with strings 5 and 6 of a tuft 4 at the position where the curtain 3 is opened. The tufted string 6 is always hung on the bottom of the tufted metal fitting 8, and the tufted string 5 is hooked on the upper part of the tufted metal fitting 8 when bundling the curtain.

FIG. 2 is a cross-sectional view of an embodiment of the hook metal fitting according to the present invention. The tufted bracket 8 includes a mounting bracket 10, a hooking member 11, a spherical member 12 fixed to the hooking member 11 with a screw 16, an elastic member 13 that constantly biases the spherical member 12, and one end of the elastic member. It is comprised with the spring support material 14 to do. The mounting bracket 10 has a concave spherical seat 10d formed in the back cavity 10c, and the convex surface 12a formed on the spherical member 12 is always pressed against the concave spherical surface 10d by the elastic member 13 so as to be freely rotatable in all directions. It is configured to slide. The elastic member 13 has an inner diameter supported by a shoulder 12c formed on the spherical member 12, and one end is securely fixed to the spherical member 12 by a spring stopper 13a, and the other is also a spring support member 14. An inner diameter is supported on the shoulder portion 14a formed on the spring 14 and is securely fixed to the spring support member 14 by a spring stopper 13b. The spring support member 14 is fixed to a recess 10 f formed on the back surface of the mounting bracket 10 by a screw 15. Therefore, even if the spherical member 12 integrated with the hooking member 11 rotates back and forth, the original neutral position is restored. Further, the hooking member 11 has a hooking head 11a for hooking the tufts 5 and 6 of the curtain, and a branched arm 11b. 9b is formed.
One end of the tuft 6 is always hung in the space 9a, and the tuft 9b after bundling the curtain is hung on the upper opening 9b.

FIG. 1 shows the overall configuration of a situation in which an electric curtain and a hook metal fitting of the present invention are attached. 1 is a cross-sectional view of an embodiment of a tufted metal fitting according to the present invention.
