Description

Anti-finger hooked louver ladder

This creation department has a louvered ladder strap for anti-finger hooking, especially a louvered ladder strap that prevents the child's fingers from pulling the drawstring, thereby avoiding the accident that the drawstring is pulled out and hooks the young child's neck. .

As shown in the first figure, a ladder belt 1 for a mesoporous louver is provided, and the ladder belt 1 is mainly composed of two parallel side ropes 11, and a support line 12 is provided at intervals to provide a The blade 2 of the middle hole 21 is placed, and the middle hole 21 is for a drawstring L1 to pass through, and the drawstring L1 is used to control the folding and lowering of the louver.

The figure shown in the second figure is another non-perforated louver ladder belt 3. The ladder belt 3 is mainly composed of two parallel side ropes 31, and a supporting wire rope 32 is provided at intervals to provide a blade 4 Putting it on, and the side rope 31 is provided with a piercing ear 33 at a predetermined distance, and the piercing ear 33 is provided with a pull string L2 for guiding, and the operator who controls the folding and lowering of the blind window by the pull rope L2 .

The above-mentioned conventional ladder belts 1, 3 have a great disadvantage that the gap between the support strands 12 or between the piercing ears 33 is large (the distance of the gap is much larger than the thickness and width of the child's finger F). Therefore, when the child pulls the ropes L1 and L2, it will accidentally pull out a considerable length and then put it into the head, and slip it off the neck a little, which may cause an unfortunate accident.

In view of this, after many times of research and improvement, the creator of this case finally completed the creation of the case, that is, the purpose of this case is to provide a slats and ladders with security against finger hooks to avoid accidents in children at home.

For the purpose of the above creation, the defensive shutter of the creation of the finger The belt is attached to two parallel side ropes, and a horizontal support line is provided at every predetermined distance. The two ends of the support line are respectively connected with the two side ropes, and the two side ropes are at least The outer side of one of the side ropes is provided with a side rope parallel thereto, and a plurality of transverse strings are densely arranged between the outer rope and the side rope to form a longitudinal threading section for pulling The string is longitudinally threaded therebetween to prevent the drawstring from being threaded by the child's fingers into the hook.

The first figure is a diagram (I) of the embodiment of the ladder belt.

The second figure is a diagram (2) of the embodiment of the ladder belt.

The third picture is a schematic diagram of the structure of the creation.

The fourth picture is a schematic cross-section of the creation.

Referring to the third figure, the finger-proof louvered ladder belt 6 of the present invention is attached to two mutually parallel side ropes 61, and a horizontal support line 63 is provided at intervals. The two ends of the wire rope 63 are respectively coupled to the two side ropes 61. The outer side ropes 61 are provided with a side rope 62 that is parallel to the outer side of the two side ropes 61. A plurality of transverse strands 641 are densely disposed with the side ropes 61 to form a longitudinal threading section 64 for longitudinally passing a drawstring 65 therebetween, thereby preventing the drawstring 65 from being pulled therebetween. It is inserted into the hook by the child's finger.

The ladder belt 6 of the above-mentioned creation, wherein the threading section 64 is threaded through the pull cord 61 and the gap D between the adjacent lateral strands 641 (as shown in the fourth figure) is less than 0.5. The centimeter, which is much lower than the thickness and width of the child's finger, has the advantage that the finger cannot be pulled into the pull cord 61, thereby effectively preventing accidents from occurring.

The pull cord 65 of the present invention passes through the threading section 64, and is threaded up and down (as shown in the fourth figure), so that the horizontal string 641 forms an obstacle to block the finger penetration of the child to ensure Effectively prevent accidents from happening.

In summary, the louvered ladder strap of the finger-proofing of the present invention is formed by blocking the insertion of the child's finger by the transverse string structure on the threading section, thereby effectively preventing accidents from occurring; Create industrial use, novelty and progressive requirements for new patents.
