Description

[Detailed description of the invention] Conventionally, long tapes or ropes used for drying clothes or as automobile towing ropes have been stored when they are not needed by winding them up manually or by using the restoring force of a spring. A method is used in which one end of the tape is connected to a spring and the tape is automatically wound.

Since the former method is done by hand, there are disadvantages such as uneven winding, tangles or crumbling, and the fact that it takes up a lot of space for storage. The latter is automatically wound up, but
It takes quite a while for long tapes to start winding from one end of the tape, and when using this method for towing a car, one end is attached to one car, but the other end has a case with a winding device. Because it is attached, it is difficult to attach it to another car, and even if it is attached, the winding device is strong enough to withstand pulling the car.
A case is required, and it is not possible to provide a compact and inexpensive product.Also, when the distance between the two vehicles changes and becomes shorter when towing, it is not possible to immediately rewind the tape, causing the tape to sag and rub against the road surface. The disadvantages are that the tape may be damaged, and when used for drying clothes, one end is a rope and the other end is a case, just like a tow rope, so the case itself is not strong, so heavy items such as futons cannot be hung. be. In addition, in general, a rope is used instead of a tape, and the rope is swung from side to side in the same way as in the method of ``winding a thread around a bobbin'', so the rope itself tends to get caught, and there are disadvantages in that it often cannot be wound smoothly and automatically.

Also, in the conventional method, it is difficult to pull with sudden force,
If the stored rope is tightened to its fullest or more force than specified is applied to the rope, the connection between the rope and the shaft may become loose or come off, causing the shaft to become tangled and prevent automatic winding. There are many drawbacks. The present invention relates to a winding storage case that eliminates the above-mentioned drawbacks and is capable of being quickly and reliably rolled up and stored compactly.

Examples of the present invention will be described in detail based on the drawings. FIG. 1 shows a completed perspective view of a shallow cylindrical storage lid 2 made of metal or synthetic resin.
There are entrances and exits 9 on the left and right sides for putting in and taking out the tape, respectively.
10 in total, two shaft rods and two entrances and exits 9, 10
are arranged on the same horizontal plane. As shown in the side view of FIG. 2, the storage lid 2 can be divided into upper and lower halves, with the upper half containing the helical spring and the lower half housing the tape. A helical spring made of metal such as alloy iron, steel plate, or synthetic resin has a spiral shape as shown in FIG. 4A, and one outer end is stored in the helical spring outer ring fixing part 4. It is fixed to the pig, and the other end of the center is fixed to the shaft rod 5 by the helical spring shaft fixing part 5. The traction tape or rope 6 made of paper, cloth, metal, or synthetic resin to be stored is made by folding the tape in half in the length direction as shown in FIG. 4B.
Insert and fix the point corresponding to 1/2 of the length of the tape into the shaft forked part 7 where the shaft rod is divided into two parts, and then insert the two overlapping tapes into the shaft rod as the center and extend the entire length of the tape. Wind it up. The ends of the finished tape are stacked in two layers, and the upper tape is taken out to the left tape entrance 10 of the storage pig, and the lower tape is taken out to the right tape entrance 9. A metal fitting 11 larger than the size of the entrance/exit opening is attached to each tip of the tape, and the end of the tape can be easily pulled out from the left and right tape entrance/exit openings 9, 10 without getting into the storage lid. The portion of the tape in contact with the shaft forked portion 7 is subject to severe wear, so it can be strengthened by weaving a flexible metal thread, carbon thread, or thick thread, or by laminating a film of metal, synthetic resin, carbon, or the like. The separating ring 8 shown in FIG. 4c, which has a diameter equal to the inner dimension of the storage lid 2 and is made of the same material as the storage lid, is in the shape of a disk or a wheel in plan view,
It is inserted coaxially between the spiral spring storage lid and the tape storage lid. Each storage pig has a spring and a tape or rope whose width corresponds to the depth.
Since the tape is divided by the separating ring 8, these spiral shapes are always kept in a single layer, so that the tape can be smoothly pulled out or stored without becoming tangled. In this case, the shaft fixing part 5 of the helical spring storage lid described above and the shaft forked part 7 of the tape storage lid are connected, or the separation ring 8 is coaxially connected to both storage lids using the same shaft rod. As shown in Figure 2,
It is completed by fixing the three parts together with fixing screws 12 from the top and bottom. The present invention has the above-mentioned structure, and when one tape that comes out from the tape inlet/outlet with the metal fitting is pulled, the other tape also comes out at the same time by the same length. This is because the entire length of the tape is folded in half and wound up, so if one end comes out 10 cm, the other ends up coming out 10 cm as well, for a total of 20 cm. Conversely, when winding the shaft is the same
If you roll it up 10cm, you can store a total of 20cm. Therefore, it has the feature of being able to pull out and wind up at twice the speed compared to conventional automatic winding. For this reason, when used as a tow rope, it can quickly react to the distance between vehicles, so the rope can always be kept taut without sagging, so you don't have to worry about damaging the rope or wrapping it around the wheels. It has the advantage of being able to be towed with peace of mind. In this case, the tape also has a forked part 7 of the shaft.
Since the tape has a structure in which it is bent in half, if the entire length of the tape is pulled out from the storage lid as much as possible, it will be in the state from A to B in Figure 5, and the structure of the helical spring and storage lid will be Regardless of strength, the tensile strength of the tape itself determines how much weight it can pull. Therefore, there is no need to increase the strength of unnecessary parts such as shafts, springs, storage lids, etc. By increasing the strength of the tape itself, it is possible to easily provide the strength that suits the application, just by changing the tape. It has the feature that it can be easily changed from a clothesline to a tow rope. While this proposal has the above-mentioned features, it is also extremely easy to handle. That is, the tape is inserted through the gap on the side of the metal fitting, passed through the metal fitting, makes a loop, and can be hung anywhere. Also, the shape is 12~ for a 5m tape tow rope.
It can be stored in a cylindrical shape with a diameter of 3 cm and a depth of 7 to 8 cm, and has the advantage that it is extremely compact and does not take up much space, does not get tangled with the rope even if carried roughly, and can be used immediately. With conventional automatic winding, there are many cases where the fixation between the shaft and the rope becomes loose due to long-term use or sudden force, or the fixed part comes off, making automatic winding impossible. ,
In this case, as mentioned above, force is applied directly to the tape, so
This type of failure does not occur at all, and it has superior durability compared to conventional products.

As mentioned above, the present invention eliminates the drawbacks of the prior art and has wide versatility as it can be used for the purpose of automatic winding and storage of clothesline, tow rope, and emergency escape rope.
