Description

A ROLLER SHUTTER STRUCTURE
FIELD OF THE INVENTION

The present invention relates to safety buckles, and particularly to a safety buckle for buckling or separating a rope and an upper beam. When a rope is pulled, the male pin will be acted so as to separate from the fastener so as to avoid a mistake from occurring.

BACKGROUND OF THE INVENTION

Referring to FIGS. 1A and 1B, a prior art curtain is illustrated. The curtain has an upper beam 1, a curtain body 2 and a control rope set 3. The upper beam has a front receiving chamber 4 and a rear receiving chamber 5. The front receiving chamber 4 can be embedded by the curtain body 2 so as to be connected to the upper beam. Another end of the curtain body 2 suspends downward. The rear receiving chamber 5 is arranged with an auto slide-stop 6 and a pulley 7. One end of the control rope set 3 is a rope 8, and another end is a rope 9. The rope 8 stops at a predetermined position by the auto slide-stop 7. The rope 9 winds around the curtain body 2. A distal end A of the rope 9 is embedded into the front receiving chamber 4 so that the rope 9 is combined to the upper beam. By pulling the rope 8, the curtain 2 can be wound upwards.
When the rope 9 winds around the curtain 2, the rope 9 will form a circle.
Generally, children can not know the danger of the circle. Once the circle encloses the neck of the child, and the rope 8 is pulled, the rope 9 will move upwards.
As a result, an accident occurs. This is because no safety structure exists between the rope 9 and the upper beam. Thereby, this prior art is dangerous at home and necessary to be improved.
SUMMARY OF THE INVENTION

According to the present invention, there is provided a safety buckle of a curtain including a curtain body and an upper beam, a distal end of the curtain body being connected to the upper beam; and a control rope set having a first end and a second end which are at opposite sides; the first end being a rope and the second end being also a rope which are interacted so as to control the curtain body to be folded upwards or to be released downward; the safety buckle comprising:
a male pin comprising a body portion and a guide end, the body portion being positioned at a bottom of the guide end and being connected to a distal end of the rope, wherein the guide has a diameter; and a fastener firmly secured to the upper beam and comprising a pin seat, the pin seat being formed on one end of a substantially circular hollow guide that protrudes outwardly from the fastener., the hollow guide has a diameter that is smaller than the diameter of the guide end of the male pin, wherein the hollow guide hole comprises an open groove that extends the length of the hollow guide so that when the guide end of the male pin passes through the hollow guide hole, the hollow guide is configured to extrude transversally to permit the passage of the male pin.
Preferably, an object of the present invention is to provide a safety buckle of a curtain including a male pin and a fastener; when a rope is pulled, the male pin will be acted so as to separate from the fastener to avoid an injury from occurring.
Still preferably, another object of the present invention is to provide a safety buckle of a curtain, wherein the male pin has a pin seat; the pin seat being formed with a hollow guide hole and an open groove. The male pin has a dome shape guide end. The guide end can be enforced into the hollow guide hole by the open groove.
Therefore, when the guide end is pulled, the male pin can be separated from the guide end by the open groove so that the male pin separates from the fastener.
Still preferably, to achieve above object, the present invention provides a safety buckle of a curtain comprises a curtain body and an upper beam, a distal end of the curtain body being connected to the upper beam; and a control rope set having a first end and a second end which are at opposite sides. The first end is a rope and the second is also a rope which are interacted so as to control the curtain body to be folded upwards or to be released downward. The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

FIG. 1 B is a cross-section view along line 1 B-1 B of FIG. 1A.
FIG. 2 is a perspective view of the curtain of the present invention.
FIGS. 3 and 4 are the exploded perspective view, assembled perspective view and cross section view of the safety buckle of the present invention.
FIGS. 5 and 6 are a cross-section view showing that the male pin is inserted into the fastener according to the present invention.

BRIEF DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring to FIGS. 2 to 3, the safety buckle of a curtain of the present invention includes an upper beam 10 which can be suspended to a window frame, a curtain body 20, a control rope set 30 for controlling the rising and descending of the curtain body 20 and a safety buckle 40.
A first end of the control rope set 30 is a rear rear rope 31 and the first end thereof is also a front rope 32. The rear rope 31 can stop the curtain body 20 at a predetermined position through the auto slide-stop 13. The front rope 32 protrudes out from the auto slide-stop 13 and the pulley 14 to wind around the curtain body 20.
By pulling the rear rope 31, the curtain body 20 will drive the front rope 32 to control the curtain body 20 so that the curtain body 20 can be wound upwards or released downward for shielding light.
With reference to FIGS. 4 to 6, one embodiment about the safety buckle 40 of the present invention is illustrated. The safety buckle 40 includes a male pin 41 and a fastener 42. The male pin 41 has a body portion 43 and a guide end 45 which has a dome shape. A distal end of the front rope 32 is firmly secured with a penetrating hole 44 of the body portion 43 so that the male pin 41 is connected to the distal end of the front rope 32. The guide end 45 is integrally formed with the body portion 43.
The fastener 42 has a first supporting sheet 46 and a second supporting sheet 47. The first supporting sheet 46 has a long hole 48. A stopper can be coupled with the long hole 48 so that the safety buckle 40 is connected to the upper beam 10. The second supporting sheet 47 is combined to a pin seat 49. The pin seat 49 has a hollow guide hole 411 and an open groove 412 which is communicable to the hollow guide hole 411. The pin seat 49 and second supporting sheet 47 is integrally formed with the first supporting sheet 46.
The guide end 45 of the male pin 41 has a middle portion 413 which has a size larger than that of the fastener 42. The diameter of the body portion 43 of the male pin is slightly smaller than the diameter of the hollow guide hole 411.
Therefore, the male pin 41 applies a push force to the body portion 43 so that the guide end 45 is inserted into the hollow guide hole 411 of the fastener 42 until the guide end 45 of the male pin 41 protrudes out of the hollow guide hole 411 of the male pin 41, as shown in FIG. 5. Finally, the outer surface of the guide end 45 is buckled to the opening 414 of the pin seat 49.
When the guide end 45 of the male pin 41 is inserted into the hollow guide hole 411 of the pin seat 49, the hollow guide hole 411 is extruded by the middle portion 413 so that the pin seat 49 suffers from a pressure as illustrated by the arrow "X". Therefore, by the function of the open groove 412, the hollow guide hole 411 will cause that the diameter of the pin seat 49 enlarges so that the guide end 45 passes through the hollow guide hole 411. Since the pin seat 49 has a sufficient clamping force, the guide end 45 is buckled to the hollow guide hole 411 so that the male pin 41 slides out from the hollow guide hole 411 of the fastener 42.
When the front rope 32 is pulled by a force over 3 KG, the male pin 41 and fastener 42 of the front rope 32 will separate from one another. This is because the guide end 45 on the male pin 41 moves downward due to a pull force indicated in the "Y" of FIG. 7. As a result, the hollow guide hole 411 is extruded transversally by the middle portion 413. As a result, the guide end 45 of the male pin 41 slides out from the hollow guide hole 411 of the male pin 41. As a result, the front rope 32 is separated from the upper beam 10 so as to prevent an accident from occurring.
Thereby, the present invention provides a preferred safety structure.
The present invention is also suitable for longitudinal folding structure, such as winding curtain, transversal Venetian shades, etc.
The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
