Light-emitting warning rope

A light-emitting warning rope is provided with one end connected to a tent and other end connected to an anchoring point. The light-emitting warning rope is disposed between the anchoring point and the tent to provide a tension to set the tent upright. The rope comprises a light-emitting core and a structural rope. The structural rope comprises a plurality of bearing yarns which is knitted into a strip body with the light-emitting core as an axis, and the strip body knitted by each bearing yarn is knitted in a mesh shape on the radial side and has a plurality of gaps through which light from the light-emitting core is transmitted. In any segment of the rope, the light-emitting core has a stretching length less than that of each bearing yarn, so that the axial tension acts substantially on the bearing yarns when the rope suffers an axial tension.

FIELD OF THE INVENTION

The present invention relates to a light-emitting warning rope, and in particular, to a light-emitting warning rope capable of withstanding a tension.

BACKGROUND OF THE INVENTION

The conventional tent consists of brackets, ropes, curtains and other components, wherein the rope is fixed between an anchoring point and the tent to provide the tent a stable supporting force. A user can nail camp nails into the ground to form anchoring points or bind the rope to a surrounding steady object such as a trunk. A camping site is usually located on the outskirts of a city or in the mountains. These locations often lack lighting. At night, campers will find it difficult to perceive where the camp rope is located. Occasionally, accidents occur in the case that the campers are stumbled and injured by ropes. In this regard, referring toFIG. 1, a cold cathode fluorescent lamp (CCFL) is used to fabricate a soft luminescent tube900in the prior art. The luminescent tube900is wound around the camp rope800and emits cold light through power to warn the user about a position where the camp rope800is located. However, the luminescent tube900will have potential safety hazards in case of accidentally leaking because of the presence of mercury. In addition, the luminescent tube900is an additional device which is hardly integrated with the camp rope800and is thus not easy to use. Because the luminous efficiency of the luminescent tube900is not ideal, it must waste a lot of power if exhibit sufficient brightness is exhibited. Therefore, it is necessary to make improvements on the prior art.

Further, the structural rope comprises a plurality of outer covering yarns which is knitted into a strip body with the plurality of bearing yarns as an axis, and the strip body knitted by each of the plurality of outer covering yarns is knitted in a mesh shape on the radial side and has a plurality of gaps for the light emitted from the light-emitting core being transmitted through.

Further, the outer covering yarns include a fluorescent dye or a light-absorbing material.

Further, the structural rope includes a light-transmitting sleeve; the light-emitting core and each of the plurality of bearing yarns are inserted inside the light-transmitting sleeve, and each of the plurality of outer covering yarns is wrapped around the outside of the light-transmitting sleeve.

Further, the light-emitting core includes a light guide strip and a plurality of luminous points provided in the light guide strip at intervals.

Further, the light-emitting core includes a first power line, a second power line provided side by side with the first power line, and a plurality of light-emitting components connected across the first power line and the second power line.

Further, the structural rope includes a plurality of reinforcing cables provided side by side with the light-emitting core; each of the plurality of bearing yarns is knitted into a strip body with the light-emitting core and each of the plurality of reinforcing cables as an axis; the reinforcing cable has a stretching length slightly larger than that of the light-emitting core in any segment of the light-emitting warning rope.

Therefore, the light-emitting warning rope of the present invention can withstand a tension through the bearing yarns, and can thus be used directly as a camp rope. The light-emitting core provides an indication light source, thereby reducing the possibility that a user is stumbled by the camp rope at night.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring toFIG. 2,FIG. 3,FIG. 4, andFIG. 5, in the present embodiment, the present invention provides a light-emitting warning rope100which mainly comprises a light-emitting core10and a structural rope20. One end of the light-emitting warning rope100is connected to a tent200, and the other end thereof is connected to an anchoring point300. The light-emitting warning rope100is disposed between the anchoring point300and the tent200to provide a tension to erect the tent200.

Specifically, in the present embodiment, the light-emitting core10includes a light guide strip14made of a light guide material, such as optical fiber, and a plurality of luminous points15disposed in the light guide strip14at intervals for scattering light. In the presence of another available light source, a user may connect one end of the light guide strip14to another light source, so that the light is scattered when passing through each of the luminous points15to achieve the effect of warning the position of a camp rope.

The structural rope20comprises a plurality of bearing yarns21which is knitted into a strip body with the light-emitting core10as an axis, and the strip body knitted by each of the bearing yarns21is knitted in a mesh shape on the radial side and has a plurality of gaps. Light emitted from the light-emitting core10is transmitted through the plurality of gaps. Each of the plurality of bearing yarns21is wound around the periphery of the light-emitting core10in any segment of the light-emitting warning rope100. Therefore, the length of the light-emitting core10is less than the length of each of the unwound bearing yarns21, and the axial tension acts substantially on the bearing yarns21when the light-emitting warning rope100suffers an axial tension. In addition, the ends of the structural rope20may include a remaining segment30. The remaining segment30is specifically a portion of a column wounded by the plurality of bearing yarns21excluding the light-emitting core10, in order to ensure that the plurality of bearing yards21preferentially sustain the axial tension force when both ends of the light-emitting warning rope100suffers an axial tension, and avoid the light-emitting core10from being torn off. Through the above-mentioned structure, the present invention utilizes the light-emitting core10to provide an indication light source, and utilizes each of the plurality of bearing yarns21as a force-bearing structure, thereby achieving the purpose of warning the position of the camp rope under the condition of suffering the tension.

Moreover, the structural rope20comprises a plurality of outer covering yarns22which is knitted into a strip body with the plurality of bearing yarns21as an axis, and the strip body knitted by each of the outer covering yarns22is knitted in a mesh shape on the radial side and has a plurality of gaps. Light emitted from the light-emitting core10is transmitted through the plurality of gaps. The plurality of outer covering yarns22serving as the outermost layer of the structural rope20, which contains a fluorescent dye or a light absorbing material (such as long-afterglow rare earth fiber) to enhance its warning effect.

In the second embodiment, the light-emitting core10includes a first power line11, a second power line12provided side by side with the first power line11, and a plurality of light-emitting components13connected across the first power line11and the second power line12. A light source of each of the light-emitting components13is disposed toward the radial direction of the light-emitting core10. Because it is difficult to get a large amount of power in a camping area, each of the light-emitting components13is preferably a light-emitting diode, which has the advantages of being driven by a weak current and energy-saving. Furthermore, the structural rope20includes a light-transmitting sleeve40. The light-emitting core10and each of the bearing yarns21are inserted inside the light-transmitting sleeve40, and each of the outer covering yarns22is wrapped around the outside of the light-transmitting sleeve40. In this way, the light-transmitting sleeve40may serve as a waterproof layer for protecting the light-emitting core10. In addition, because each of the light-emitting components13has a thickness, so that grainy protrusions are generated on the surface of each of the outer covering yarns22. The coverage of the light-transmitting sleeve40also has the benefit of making the light-emitting warning rope100more smooth in appearance and touch.

FIG. 8illustrates a third embodiment of the present invention. In order to improve the tensile strength of the structural rope20, the structural rope20may include a plurality of reinforcing cables23provided side by side with the light-emitting core10. Each of the bearing yarns21is knitted into a strip body with the light-emitting core10and each of the reinforcing cables23as an axis. In addition, the reinforcing cable23has a stretching length slightly larger than that of the light-emitting core10in any segment of the light-emitting warning rope100. Each of the reinforcing cables23may be made of a material the same as each of the bearing yarns21, or may be made of a material with higher structural strength such as a metal wire.
