[0002] As the quality of life for citizens improves and awareness levels gradually rise, the frequency of various festivals, competitions, rallies, and demonstrations held in public places is increasing compared to the past; in particular, when festivals or demonstrations occur unexpectedly in unspecified areas, the emergency deployment of public authorities, such as the police, is required to maintain order.

[0003] For these various types of demonstrations to become democratic and autonomous, more advanced order lines must be used; however, current order lines are ineffective. For general demonstrations, officers on duty must hold safety tape with both hands, restricting their hands from being free, while for specific demonstrations, barricades are used. However, due to their fixed nature, transporting, installing, and retrieving them is cumbersome, and their visibility is poor. Furthermore, it is difficult to respond appropriately when crowds are moving, resulting in poor usability.

[0004] In addition, looking at the prior art smart order maintenance line device (Republic of Korea Registered Patent 10-2418066), there is an advanced concept of an order maintenance line such as winding, detaching, and attaching the maintenance line, but this is also in the form of a fixed support rod structure with wheels attached thereto, and like current order maintenance lines, transportation, installation, retrieval, and mobility are limited. The problem to be solved

[0005] The present invention aims to provide a portable order maintenance device with excellent usability, which is easy to install and retrieve, and allows individual workers to carry and attach the order maintenance device to their waist in order to solve the various problems that occur in fixed order maintenance lines as described above. means of solving the problem

[0007] The main body case includes a power switch on the upper lid for flashing the light-emitting part of the retaining wire, an upper rod supporting the retaining wire rotation shaft, a stop button module at the bottom for controlling the unwinding and winding of the retaining wire, and a battery for supplying power to the light-emitting part;

[0008] The power switch includes a push-pull module composed of a Jabra-type terminal that connects power to the power connection cap of the rotating shaft connection part;

[0009] The retaining wire module includes a retaining wire having a light-emitting part, and a rotating shaft connection part connected to a retaining wire rotation shaft that rotates and unwinds and winds the retaining wire;

[0010] The rotary shaft connection part is characterized by including a power connection cap that connects power from a power switch fixed to the main body case to the retaining wire light-emitting part. Effects of the invention

[0011] The portable order maintenance line device of the present invention, configured as described above, has the advantage of excellent usability, allowing individual workers to attach it to their waists and quickly deploy to the scene, immediately establish an order maintenance line by connecting the line loop to the belt of an adjacent worker, and enable flexible on-site response by allowing both hands to be free, visibility to be easy, consistent maintenance of the order maintenance line while moving together with the crowd, and immediate extension or shortening of the order maintenance line as the crowd's ranks increase or decrease.

[0013] A portable order maintenance line device according to one embodiment of the present invention as described above will be explained with reference to the drawings as follows; however, this is an explanation based on one embodiment, and the present invention is not limited to the following embodiment and can be implemented in various modules and forms.

[0014] FIG. 1 is a front view of the portable order maintenance line device of the present invention, FIG. 2 is a side perspective view of FIG. 1 with the maintenance line pulled, and FIG. 3 is a top view and a bottom view of FIG. 1.

[0015] Referring to FIGS. 1 and 2, a portable order maintenance line device (100) according to one embodiment of the present invention is composed of a main body case (105), a waist belt (130a, 130b), and a maintenance line module (160).

[0016] The main body case (105) is in the shape of a cylinder and has one side curved so that it can be tied around the waist using a waist belt (130a, 130b). It includes an upper lid (120) and a lower lid (140) so that components can be easily assembled and mounted. The main body case (105) is configured to be assembled in two parts.

[0017] On the upper lid (120) of the upper surface of the main body case (105), there is a power switch (110) and a USB battery charging terminal (115). By pressing the power switch (110) of the upper lid (120), the light-emitting parts (162a, 162b) attached to the maintenance wire (161) can be flashed, and the battery (270) installed inside can be charged through the USB battery charging terminal (115). The operation of the power switch (110) will be explained later in FIGS. 7 and 8.

[0018] A mainspring (250) that winds and unwinds the retaining wire (161) is mounted and fixed to the lower lid (140) of the main body case (105), and a circular groove is formed in the center of the interior so that the retaining wire rotation shaft (241) can rotate.

[0019] A rectangular through hole is formed on the front right side of the main body case (105) so that the internal retaining wire (161) can be pulled outward and wound, and the stopping and winding of the retaining wire (161) is controlled by a stop button (150) on the lower left side of the retaining wire (161), and the operation of the stop button (150) will be explained later in FIGS. 9 and 10.

[0020] The retaining wire (160) module on the front right side of the main body case (105) is configured to include a retaining wire (161), a light-emitting part (162a, 162b), a retaining wire ring (165), and a rotation shaft connection part (230), and is connected to the retaining wire rotation shaft (241) inside the main body case (105) via the rotation shaft connection part (230), so that it can be wound and unwound by the tension of the mainspring (250).

[0021] The rear of the main body case (105) is curved, and waist belts (130a, 130b) are attached to the left and right ends of the rear. After tying the belt pin (131a, 131b) around a worker's waist, the maintenance line (161) is pulled out and the maintenance line loop (165) is connected to the waist belt loop of an adjacent worker (see FIG. 4) to form an order maintenance line, and the order maintenance line can be continuously extended in this manner.

[0022] FIG. 5 is a component configuration diagram inside the main body case (105) including a main spring (250), a retaining pivot shaft (241), a wire connection cap (220), and a stop button module (260), which are connected and supported to the main body case (105) by an upper lid (120) and a lower lid (140).

[0023] The mainspring (250) is inserted into the lower lid (140), and its outer end is inserted into the groove of the lower lid (140) to be fixed, and its inner end is inserted into the groove of the lower projection (243) (see FIG. 6) of the retaining rotation shaft (241) so that the spring is wound when the retaining rotation shaft rotates.

[0024] The retaining pivot shaft (241) is integrally formed with the rotating rod (240), and the rotating rod (240) has a rectangular groove into which the pivot shaft connection part (230) can be inserted and a groove into which the wire connection cap (220) can be attached to the upper part.

[0025] The lower projection (243) of the retaining wire rotation shaft (241) passes through the mainspring (250) and is inserted into the circular groove at the center of the lower lid (140), and the rotating rod (240) is inserted into the upper rod (121) of the upper lid (120) after the wire connection cap (220) is attached to the upper inner side and is supported by the main body case (105) so that it rotates when the retaining wire (161) is unwound and wound.

[0026] The wire connection cap (220) is a power connection part between the wire of the retaining wire (161) and the power switch (110) of the upper lid (120), and is described later in FIG. 6.

[0027] The stop button module (260) is supported in a hinge shape on the inner wall of the main body case (105) and can control automatic stopping and winding when the holding line (161) is pulled by linking with the stop button (150) on the outside of the main body case (105), as described later in FIGS. 9 and 10.

[0028] FIG. 4 is a configuration diagram of a maintenance wire module (160) and is composed of a maintenance wire (161), light-emitting parts (162a, 162b) attached to the upper and lower ends of the maintenance wire (161), and a rotating shaft connection part (230) for connecting the wires of the light-emitting parts (162a, 162b) to a wire connection cap (220).

[0029] Each light-emitting part (162a, 162b) is in the form of a strip in which each light-emitting part is connected in a parallel circuit, and the circuit in the direction of the retaining wire loop (165) is a closed circuit to supply power to the light-emitting part. For example, in the case of the light-emitting part (162a), the positive electrode (indicated as “+” in FIG. 4) of the light-emitting part (162a) and the positive wire (231a) of the rotating shaft connection part (230) are connected, and the negative electrode (indicated as “-” in FIG. 4) of the light-emitting part (162b) and the negative wire (231b) of the rotating shaft connection part (230) are connected.

[0030] Each light-emitting part (162a, 162b) may use direct lighting such as mini LEDs as an example, but is not limited thereto and may also use indirect lighting such as optical fibers (not shown).

[0031] The retaining wire (161) is connected to the rotating shaft connection part (230), and the rotating shaft connection part (230) is inserted into the rotating rod (240) of the retaining wire rotating shaft (241), so that when the retaining wire is unwound or wound, the retaining wire rotating shaft (241) rotates clockwise and counterclockwise by the tension of the mainspring (250).

[0032] At this time, the positive wire (231a) and negative wire (231b) of the rotating shaft connection part (230) are fixed within the rotating shaft connection part (230), so that when the retaining shaft (241) rotates, they rotate together with the rotating rod (240) to prevent the wires from twisting.

[0033] FIG. 6 is a power connection configuration diagram for supplying power to the light-emitting parts (162a, 162b) of the maintenance line (161), in which the positive electrode (indicated by “+”) of the battery (270) and the switch positive electrode (213a) are connected, and the negative electrode (indicated by “-”) and the switch negative electrode (213b) are connected.

[0034] At this time, the terminals of the switch positive electrode (213a) and the switch negative electrode (213b) are formed by folding a metal strip in a zigzag manner to give the terminals a Jabra spring elasticity so that they can always make constant contact with the wire connection cap (220).

[0035] The upper part of the wire connection cap (220) is a flat circular shape, and a circular metal strip (221b) is formed on the outer part, with one end penetrating the wire connection cap (220) to form a negative terminal (222b) at the bottom, and a circular metal plate (221a) is formed on the inner part, with one end penetrating the wire connection cap (220) to form a positive terminal (222a) at the bottom.

[0036] After the positive terminal (222a) formed on the wire connection cap (220) and the positive wire (231a) of the rotating shaft connection part (230), and the negative terminal (222b) and the negative wire (231b) of the rotating shaft connection part (230) are each combined, the wire connection cap (220) is inserted into the inside of the rotating rod (240), and thereafter, when the holding shaft (241) rotates, it rotates in the same way, so that the power can be connected without the wire between the power switch (110) with a fixed position and the rotating shaft connection part (230) being twisted.

[0037] The push-pull type power switch (110) is normally in a power-off state due to the tension of the spring (211) of the power switch (110), but when the power switch (110) is pressed, the positive terminal (213a) of the switch is connected to the positive terminal (222a) of the wire connection cap (220) and the negative terminal (213b) of the switch is connected to the negative terminal (222b) of the wire connection cap (220), thereby supplying power and making the light-emitting parts (162a, 162b) of the maintenance wire (161) flash, and this is independent of the rotational position of the wire connection cap (220).

[0038] FIG. 7 is a power cut-off state of the power switch (110), FIG. 8 is a power connected state of the power switch (110), and the power switch (110) is toggled each time it is pressed.

[0039] FIGS. 9 and 10 illustrate the button operation during the unwinding and winding of the retaining wire (161). A stop button module (260) is formed in a hinge-like manner on the inner wall of the main body case (105) in close contact with the retaining wire rotation axis (241). The stop button module (260) is coupled with a stop button (150) outside the main body case (105), and a rotation axis projection (242) is raised low in a triangular shape in a counterclockwise direction on the retaining wire rotation axis.

[0040] In FIG. 9, when the holding line (161) is pulled, the holding line rotation axis (241) rotates clockwise as shown by arrow A. At this time, the front wing (261) of the stop button module (260) receives a force in the F direction due to the tension of the spring (263) and comes into close contact with the rotation axis projection (242). However, the inclination of the front wing (261) is triangular in shape, the same as the direction of the rotation axis projection (242), so it does not hinder rotation. However, when the pulling of the holding line (161) stops, the holding line rotation axis (241) rotates counterclockwise due to the restoring force of the mainspring (250). At this time, the rotation axis projection (242) becomes in an inverted triangular direction opposite to the front wing (261) and gets caught on the front wing (261), causing the holding line (161) to stop in the pulled state.

[0041] In FIG. 10, the winding of the holding line (161) in a pulled and stopped state is achieved by pushing the stop button (150) in the S direction to apply a force in the F direction, causing the front wing (261) to detach from the rotation axis projection (242) and at the same time the rear wing (262) to come into contact with the rotation axis projection (242). As a result, the holding line rotation axis (241) rotates counterclockwise as indicated by arrow B, but the rotation axis projection (242) is caught on the rear wing (262), allowing for a gentle winding, thereby enabling safe use of the light-emitting parts (162a, 162b) attached to the holding line (161).
