Description

Technology Field

[0001] The present invention relates to a portable elastic winding traffic safety roll strap that allows a driver of a vehicle to identify pedestrians with high visibility by having a flexible material safety strap surrounding an object of use, such as an upper body, bag, or bicycle, glow by an external light source. More specifically, the invention relates to a portable elastic winding traffic safety roll strap that maximizes portability, ease of use, and utility through a tape measure-like structure in which a safety strap compactly housed in the internal space of an elastic winding hole unwinds out according to the user's unwinding motion and surrounds the object of use. Background Technology

[0003] Recently, in response to demands for stricter punishment for child traffic accident victims, penalty regulations for traffic accidents within child protection zones have been strengthened, and applicable traffic laws have become more stringent. A child protection zone (School Zone) is a designated section of road surrounding facilities for children under the age of 13, such as elementary schools, kindergartens, daycare centers, and private academies. Its purpose is to prevent traffic accidents by securing safe commuting spaces for children through the installation of traffic safety facilities and road accessories. Under the Road Traffic Act, the speed limit for vehicles in child protection zones is restricted to 30 kilometers per hour, and once designated, road accessories such as traffic signals and safety signs may be installed. However, because the surroundings are dark on rainy days or at night, it is difficult to recognize child protection zones, hindering proper slow-speed driving. Furthermore, as sufficient means are not provided for drivers to identify children attempting to cross the road, traffic accidents within child protection zones continue to occur.

[0005] Furthermore, traffic accidents caused by drivers failing to identify pedestrians, including children, occur frequently even in traffic areas outside of child protection zones. As a countermeasure against this, technologies related to traffic seat belts have been developed and are in use, including the "Traffic Seat Belt for Children" (Republic of Korea Published Utility Model Publication No. 10-1997-0019344), the "Safety Band" (Registered Utility Model Publication No. 20-0375428), and the "Seat Belt with Self-Luminous Means" (Registered Utility Model Publication No. 20-0234911). Traffic seat belts wrap around parts of the bodies of pedestrians, including children, roadside and construction site workers, and sanitation workers, and improve pedestrian visibility for drivers through functions such as light reflection, fluorescence, and luminescence.

[0007] In addition, as shown in Figures 8 (a) and (b), fluorescent bag covers and safety key rings for children are distributed and used through educational institutions. However, the fluorescent bag covers cause significant inconvenience and hassle in both the step of putting them on the bag and the step of removing them from the bag, as well as in the step of storing the removed covers separately and reusing them. Furthermore, the safety key rings have limitations in that their safety prevention effect is significantly reduced due to their small size. Prior art literature

Specific details for implementing the invention

[0033] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. Meanwhile, in the drawings and detailed description, the illustration and mention of configurations and operations that are easily understood by those skilled in the art have been simplified or omitted. In particular, in the drawings and detailed description, detailed descriptions and illustrations of specific technical configurations and operations of elements not directly related to the technical features of the present invention have been omitted, and only the technical configurations related to the present invention have been briefly illustrated or described.

[0035] A portable elastic winding traffic safety roll strap according to an embodiment of the present invention is composed of a safety belt (200) and an elastic winding member (100) as shown in FIG. 1.

[0037] The safety belt (200) is made of a flexible material and has a length that can wrap around an object of use. On the surface of such a safety belt (200), a retroreflective material, a fluorescent material, a light source, etc. are formed in the longitudinal direction, so that the safety belt (200) wrapping around the object of use glows when exposed to an external light source, thereby inducing improved visibility. The object of use may include the user's upper body, a bag, a bicycle, etc.

[0038] Here, the safety belt (200) according to an embodiment of the present invention is composed of a base layer (210) and a functional surface layer (220).

[0039] The base layer (210) is made of a thin sheet with a rectangular horizontal cross-section having a set width, and may be made of a flexible synthetic resin material, fiber material, etc. The functional surface layer (220) is made of any one selected from a retroreflective material, a fluorescent material, or a group of light emitters, and is applied, coated, or attached to the upper and lower surfaces of the base layer (210). The functional surface layer (220) may be applied, coated, or attached to the entire upper / lower surface of the base layer (210), or may be applied, coated, or attached to a part of the upper / lower surface in the width direction as shown in FIGS. 3 and 4.

[0041] The elastic winding member (100) is formed as a case having an internal space in which the safety belt (200) is elastically wound, and the elastic winding member (100) can be formed as a circular elastic winding member (100') as shown in FIG. 2. Here, the elastic winding member (100)(100') can be formed as a tape measure structure having a coil spring provided inside.

[0042] The elastic winding member (100) allows the safety belt (200), which is unwound from the internal space according to the user's unwinding motion, to surround the object of use. Since the safety belt (200) is structured to be given elastic force by the elastic winding member (100), when it surrounds the object of use as shown in FIGS. 6 and 7, it can maintain a tension of a set size, thereby continuously maintaining the initial shape (shape exemplified in FIGS. 6 and 7) that surrounds the object of use without sliding down from the object of use. Meanwhile, the elastic winding member (100) is equipped with a return switch (110) as shown in FIGS. 1 and 2, which causes the safety belt (200) to be wound back into the internal space of the elastic winding member (100) when the use of the safety belt (200) ends. In addition, the elastic winding member (100) may be equipped with a fixing clip (120) that can be fixed to the user's waistband as shown in FIG. 1.

[0043] The elastic winding member (100) according to an embodiment of the present invention is equipped with a coil spring (150) to which the safety belt (200) is connected. The coil spring (150) is used to have a spring constant value such that the maximum tension applied to the safety belt (200) unwound by the user's unwinding motion is less than or equal to a set size, thereby preventing safety accidents caused by the rapid return of the safety belt (200) to its original position. In particular, the elastic winding member (100) according to an embodiment of the present invention is additionally equipped with a friction resistance body (160) that applies frictional force to the safety belt (200) when the safety belt (200) unwound by the user's unwinding motion returns to its original position, as shown in FIG. 5, thereby preventing safety accidents caused by the rapid return of the safety belt (200) to its original position. The friction resistance body (160) may be made of a material with a high friction coefficient and may be in close contact with the seat belt (200), or it may be made of a shape structure that increases frictional force by constantly contacting the seat belt (200) returning to its original position or intermittently contacting the seat belt (200) returning to its original position.

[0045] Meanwhile, the portable elastic winding traffic safety roll strap according to the present invention may be equipped with a latch (300) as shown in FIGS. 1 and 2, and the latch (300) is fixed to the end portion of the safety belt (200) and is formed in the shape of a loop.

[0047] In contrast, the portable elastic winding traffic safety roll strap according to the present invention may be equipped with a buckle-type fixing member (400) as shown in FIG. 3, wherein the buckle-type fixing member (400) consists of a buckle (420) and a clip (410) that are respectively connected and fixed to the end portion of the safety belt (200) and the elastic winding member (100). The buckle (420) and the clip (410) of such a buckle-type fixing member (400) are combined with each other so that the safety belt (200) is fixed to the object of use.

[0049] In addition, the portable elastic winding traffic safety roll strap according to the present invention may be equipped with an elastic deformation catch (500) and a catch fixing band (140) as shown in FIG. 4. The elastic deformation catch (500) is fixed to the end portion of the safety belt (200), is formed in a loop shape, and opens and closes as a cut portion is elastically deformed. The catch fixing band (140) is connected and fixed to the elastic winding member (100).

[0050] After opening and closing the elastic deformation catch (500) as described above, one or more selected modes are combined from among 1) a fixing mode in which the elastic deformation catch (500) is fixed to another part, 2) a safety belt fixing mode in which a part of the safety belt (200) is fixed to the elastic deformation catch (500), 3) a safety belt passing mode in which the safety belt (200) passes through the elastic deformation catch (500), and 4) a catch-winding combination mode in which the elastic deformation catch (500) is caught and fixed to the catch fixing band (140), thereby fixing the safety belt (200) to the object of use.

[0052] The portable elastic winding traffic safety roll strap according to the embodiment of the present invention configured as described above provides 1) a tape measure-like structure in which a safety belt wound in a roll shape within the internal space of an elastic winding member made of a small case is unwound according to the user's unwinding motion, and 2) an intuitive safety belt usage structure in which the user freely wraps the safety belt around the object of use according to the situation without a fixed format, thereby maximizing portability, ease of use, and usability.

[0054] Although a portable elastic winding traffic safety roll strap according to an embodiment of the present invention has been illustrated in accordance with the description and drawings above, this is merely for illustrative purposes, and those skilled in the art will understand that various changes and modifications are possible within the scope of the technical spirit of the present invention.
