Description

  The present invention relates to a tufted metal fitting that can self-release the tufting when the 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 opened and closed freely even when bedridden by remote control operation (remote operation). 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. Thus, the remote control of the electric curtain is operated in a state where the curtain is fixed to the tuft, and 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 three 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.
Patent publication 2004-216079 Thirdly, when the hook member and the spherical member are fixed with normal screws, the screw tends to loosen due to the frequent rotation of the hook member, and both ends of the elastic member are rotated and bent. On the other hand, it is difficult to fix securely, the elastic member is detached, and as a result, the hook metal fitting is often damaged, and such unintentional self-hook release cannot be performed. This will cause the worst trouble. Japanese Patent Application No. 2006-078067

Therefore, especially in the case of nursing homes and hospitals, many healthy people, people with disabilities, and elderly people can safely release themselves even if they pull the electric curtain, operate the remote control, or hang it. There is a demand for a high-quality tufted metal fitting.
In addition, when closing the curtain even in ordinary households, it is possible to unfasten the tufts and close the bundled curtains safely and securely by pulling the curtains slightly without removing the tufts. Recently, it is also desired to increase.

  In order to solve such problems, the tufting is surely self-released when the curtain is forcibly pulled, and in many cases, the hook metal fitting is connected to the spherical member, and both ends of the elastic member are fixed. Is made surely so that no looseness occurs.

A hollow half-spherical spherical member 12 having a mounting surface 10 having a concave spherical seat 10d formed on the opening side and having a convex surface 12a that slides freely while being stretched to the concave spherical surface 10d by an elastic means 13 at all times. The spherical member 12 and the hook member 11 are securely coupled to each other by a nut 17 through a shaft 15 extending substantially through the center of the spherical member 12, and the elastic member 13 has both ends at the shaft 15. The other end 15a is fixed by a nut 18 and a shoulder 10e formed on the back surface of the mounting bracket 10 and a screw 16 so that the rotational movement is securely fixed and biased. Provide a self-releasing tufted metal fitting.

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.
When the curtain 3 is bundled by the tuft 4 and the tuft 5 is hung on the hook head 11a of the hook member 11, the tuft 5 does not fall to the bottom of the hook 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.
Further, the hollow half-shaped spherical member 12 is fastened together with the shoulder 15d of the shaft 15 and the hooking member 11 with the nut 17, so that the hemispherical end 12b of the spherical member bites into the recess 11c of the hooking member 11. Fixed to. The elastic member 13 is securely fixed at one end with a screw 16 and the other end is fixed to the spring support member 14 by welding or nut fastening, so that both ends are securely fixed against any movement of the elastic member 13. Is done.

When operating the electric curtain with the remote control, use the main hook metal fittings as a set to ensure safety even when the curtain is unintentionally bundled with tufts. Furthermore, it is convenient to use the self-releasing hook metal fitting when it is desired to use a normal method of releasing the tuft by pulling the bundled curtains slightly.

FIG. 1 shows a state in which an electric curtain and a hook metal fitting of the present invention are attached in an overall configuration. 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 column 7 with strings 5 and 6 of a tuft 4 of the curtain at a 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 metal fitting 8 includes a mounting metal 10, a hooking member 11, a hollow half spherical member 12 fixed to the hooking member 11 via a shaft 15 via a shaft 17, and an elastic member that constantly urges the spherical member 12 toward the pulling side. 13 and a spring support member 14 that supports one end of the elastic member 13. The mounting bracket 10 has a concave spherical seat 10d formed on the opening side, and the convex surface 12a formed on the spherical member 12 is slid freely in all directions while being always pressed against the concave spherical surface 10d by the elastic member 13. It is the composition to do. Further, the hollow half-shaped spherical member 12 is fastened together with the shoulder 15d of the shaft 15 and the hooking member 11 with the nut 17, so that the hemispherical end 12b of the spherical member bites into the recess 11c of the hooking member 11. It becomes the composition fixed to.
One end of the elastic member 13 is securely fixed to the shoulder portion 10d of the hook metal fitting 10 with a screw 16, and the other end of the elastic member 13 is joined to the end portion 14a of the spring support member 14 by welding. Again, both ends are securely fixed. The female key 14b formed on the spring support member 14 is fitted with a male key groove 15c formed on the shaft 15 so that the movement in the rotational direction is restricted, and the nut 18 and one end of the shaft 15 are fitted. The spring support member 14 is fixed to the shaft 15 by a screw portion 15a formed on the shaft 15a. Therefore, even if the spherical member 12 integral with the hooking member 11 is rotated back and forth and back and forth, the elastic member 13 restores the original neutral position. The fixing of will not come off.
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 5 after bundling the curtain is hung on the upper opening 9b.

FIG. 3 is a cross-sectional view of another embodiment of the hook metal fitting according to the present invention. In particular, the seat member 19 is disposed separately in the opening of the hook metal fitting 10 ', and the spring support member is also used as a shaft. The seat member 19 has a concave or convex spherical surface 19a that freely abuts on the hollow half-shaped spherical member 12 'and includes a cylinder portion 19b that fits into the hole 10'h of the mounting bracket. Yes. One end of the elastic member 13 ′ is fitted to the inner diameter side of the cylinder portion 19b and the hook metal fitting 10 ′ and is securely fixed by the screw 16 ′. Further, the seat member 19 has an advantage that it is hardened by heat treatment and becomes strong against wear.
Further, the screw portion 15′a formed at the other end of the shaft 15 ′ has a groove portion 15′b.
