Description

Technical Field

[0001] The present invention relates to a triangular warning sign, and more particularly, to a portable folding safety triangular warning sign that is provided to be automatically unfolded and can be folded and stored inside a case when folded.

Background Art

[0002] Generally, when a vehicle stops on a road such as a highway due to an accident or vehicle failure, after quickly moving the vehicle to the road shoulder while checking the surrounding traffic conditions, a safety triangular warning sign is installed behind the vehicle to guide the drivers of the following vehicles to look ahead, thereby preventing secondary accidents.

[0003] In the case of a highway, in the event of a vehicle safety accident or failure, since there is no display of a front obstacle like a triangular warning sign, in the case of a secondary accident where a following vehicle collides with a preceding vehicle, the preceding vehicle is imposed with a civil damage compensation liability of 30 - 40%. At night, the liability is further strictly pursued and the preceding vehicle is imposed with a liability of 50 - 60%.

[0004] Conventionally, a folding triangular warning sign is carried in a vehicle, and when a vehicle accident or failure occurs, the triangular warning sign is assembled and erected on the road surface at a certain distance behind the vehicle to guide the drivers of the following vehicles to look ahead.

[0005] For such a conventional triangular warning sign, since a driver of a faulty or accident vehicle has to move to the installation position of the triangular warning sign to install it, a personal accident of colliding with a following vehicle may occur during the moving process or the process of assembling the triangular warning sign. Frequently, the installed triangular warning sign is blown away by the wind and falls down, and thus cannot perform its original function properly. Also, most triangular warning signs do not emit light by their own light-emitting means, but are configured to reflect the headlight of a following vehicle so that the driver of the following vehicle can recognize it by the reflected light. Therefore, in bad weather such as rainy days or when thick fog occurs, there are cases where the driver recognizes the reflected light of the triangular warning sign late and cannot respond properly.

[0006] In order to solve such problems, in fact, there is a need for a safety triangle display board that can be carried around and can be quickly installed.

Summary of the Invention

Problems to be Solved by the Invention

Embodiments for Carrying out the Invention

[0019] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0020] The advantages and features of the present invention, and how to achieve them, will become clear when you refer to the embodiments described in detail below with the accompanying drawings.

[0021] However, the present invention is not limited to the embodiments disclosed below and may be embodied in a variety of different forms, provided that these embodiments complete the disclosure of the present invention and fully inform those skilled in the art of the invention of the scope of the invention, and the present invention is defined only by the scope of the claims.

[0022] Furthermore, in explaining the present invention, if it is determined that related prior art or other information may obscure the gist of the invention, a detailed explanation thereof will be omitted.

[0023] The present invention relates to a portable, foldable safety triangle warning sign, and its configuration can broadly include a main body 100 and a case 200.

[0024] First, the main unit 100 can be a means of informing following vehicles that a vehicle has stopped on a road with smooth traffic due to a breakdown or emergency.

[0025] For this purpose, the main body 100 may be provided in a triangular shape, with a reflector or LED inserted on one side. Before describing the present invention, we will explain two embodiments separately.

[0026] [First Embodiment] The main body 100 is formed by long bars that can be rotatably joined to each other at their ends, so that it can be folded into a long bar shape for portability and automatically unfolded into a triangular shape for use.

[0027] On the other hand, the case portion 200 is formed to correspond to the shape of the main body portion 100 when it is folded, and is provided so that the main body portion 100 can be inserted into it. A standing groove 220 may be formed in part along the longitudinal direction so that when the main body portion 100 is unfolded, one of the three bars can be inserted to make the main body portion 100 stand upright.

[0028] The present invention will be described in detail with reference to the drawings.

[0029] Figure 1 is a diagram illustrating the overall appearance of a portable foldable safety triangle warning board according to the first embodiment of the present invention, Figure 2 is a diagram illustrating the main body 100 and case 200 of the portable foldable safety triangle warning board according to the first embodiment of the present invention, and Figure 3 is a diagram illustrating the state in which the main body 100 is folded and inserted into the case 200 of the portable foldable safety triangle warning board according to the first embodiment of the present invention.

[0030] As illustrated, the triangular warning sign can be characterized by being inserted into the case portion 200 and standing upright.

[0031] For this reason, it is preferable that the thickness of the bar inserted into the case portion 200 has a thickness corresponding to the vertical groove 220 of the case portion 200.

[0032] In the first embodiment of the present invention, the triangular warning signs may have a stacked shape when folded, overlapping each other, and be arranged in a triangular shape when unfolded.

[0033] As shown in Figure 2, the main body 100 and the case 200 according to the first embodiment of the present invention are placed side by side.

[0034] The main body 100 has a stacked shape in which three bars overlap each other when folded, and the three bars may have the same length and width.

[0035] Furthermore, the case portion 200 can have a shape that corresponds to the shape of the main body portion 100, while also having a size that surrounds the main body portion 100.

[0036] Furthermore, it can be confirmed that a vertical groove 220 is formed in the center of one surface of the case portion 200.

[0037] As described above, the upright groove 220 can be formed to have one of the upper bar 120, lower bar 160, and middle bar 140 that make up the main body 100 inserted into it, and the groove can be formed to be the same thickness as or relatively larger than one of the inserted bars 120, 140, or 160.

[0038] This is to ensure that the main body 100 stands upright when it is inserted into the upright groove 220. Although the upright groove 220 is formed to be a predetermined size along the longitudinal direction of the case 200, even if it is formed to be predetermined size larger than the thickness of any one of the inserted bars 120, 140, or 160, it may still be supported at a predetermined angle.

[0039] Furthermore, a gripping groove 210 may be formed at one end of the case portion 200 along its longitudinal direction.

[0040] First, the case portion 200 may be formed by arranging faces of the same length so that they are spaced apart from each other and parallel, with one end open and the other end protruding in a semicircular shape.

[0041] This may be the same as when the main body 100 is folded in a stacked configuration, that is, when it is in a straight shape, and the ends are formed in a semi-circular shape.

[0042] Furthermore, one end of the case portion 200 on which the gripping portion is formed may have a semi-circular recessed shape, as if a circular piece had been cut off from the end of the case portion 200.

[0043] In other words, by cutting a circle from a shape with a protruding semicircle, a semicircular groove can be formed that is recessed towards the center along the longitudinal direction.

[0044] This may be for quickly removing the main body 100 inserted into the case 200 by virtue of the present invention being provided for portable use.

[0045] Therefore, the user can hold the case 200 with one hand, and with the other hand, hold the case 200 with the thumb and index finger through the gripping groove 210 and take it out with the case 200.

[0046] Next, the main body 100 will be described.

[0047] The main body 100 has a shape in which three bars are stacked when folded, and the three bars can include an upper bar 120, a middle bar 140, and a lower bar 160.

[0048] In this embodiment, the upper bar 120 and the lower bar 160 are provided in the same shape as each other, and the upper and lower layers can be changed by selecting the front and rear surfaces.

[0049] Therefore, by designating the upper bar 120 and the lower bar 160 according to the first embodiment of the present invention, the scope of rights is not limited. As described above, the upper bar 120 and the lower bar 160 can be replaceable with the same shape as each other.

[0050] In the present invention, the form in which the main body 100 is folded is such that the first bar 142 and the second bar 144 move toward the coupling part where the upper bar 120 and the lower bar 160 are coupled, and at the part where the first bar 142 and the second bar 144 are coupled, the upper bar 120 overlaps with one surface of the first bar so as to contact one surface of the upper bar 120, the other surface of the first bar 142 overlaps with one surface of the second bar 144, and the other surface of the second bar 144 overlaps with one surface of the lower bar 160, and when folded, it can be deformed into a "one" shape.

[0051] The triangular display board according to the first embodiment of the present invention will be specifically described through the following drawings.

[0052] FIGS. 4 to 8 are drawings for explaining the main body 100.

[0053] Figure 4 is a diagram illustrating the overall configuration of a portable foldable safety triangle warning board according to the first embodiment of the present invention; Figure 5 is a diagram illustrating the appearance of the portable foldable safety triangle warning board according to the first embodiment of the present invention when it is unfolded; Figure 6 is a diagram illustrating the separation portion 180 of the portable foldable safety triangle warning board according to the first embodiment of the present invention; and Figures 7 and 8 are diagrams illustrating the configuration of the portable foldable safety triangle warning board according to the first embodiment of the present invention that is provided to unfold automatically.

[0054] First, let's explain the main body 100 using Figure 4, which is an exploded view of the main body 100.

[0055] As shown in the diagram, the main body 100 may be composed of an upper bar 120, a lower bar 160, a middle bar 140, a bearing section 170, and a separation section 180.

[0056] In the illustrated drawing, the two relatively long bars are the upper bar 120 and the lower bar 160, while the relatively shorter bar is the middle bar 140.

[0057] The upper bar 120 and lower bar 160 are arranged from the outermost top downwards, and the middle bar 140 may be in the order of the first bar 142 and the second bar 144.

[0058] The upper bar 120 and the lower bar 160 can be formed to be long and have the same width and height.

[0059] The two ends then become connecting parts that are joined together, and the connecting parts can have the shape of a circular groove (not shown in the drawing reference numerals) or a projection (not shown in the drawing reference numerals) that is predetermined to protrude from the center of the groove.

[0060] The joint between the upper bar 120 and the lower bar 160 can be connected by having a separation portion 180 positioned between them.

[0061] The separation portion 180 is provided at the joint where the upper bar 120 and the lower bar 160 are joined, so that the upper bar 120 and the lower bar 160 can each rotate, and the separation portion 180 may be provided with a thickness corresponding to the thickness of the middle bar 140.

[0062] In this configuration, according to the first embodiment of the present invention, the connecting portions of the upper bar 120, the lower bar 160, and the middle bar 140 are arranged to overlap each other, and the connecting portions of the upper bar 120 and the lower bar 160 are separated by an amount corresponding to the thickness of the middle bar 140, so that the separating portion 180 can be inserted.

[0063] Here, the separation portion 180 may be provided on both sides in the form of bearings along the stacking direction.

[0064] One possible reason for this is to reduce friction when the upper bar 120 and lower bar 160 are folded or unfolded.

[0065] On the other hand, the intermediate bar 140 includes a first bar 142 and a second bar 144, and the joint portion where the first bar 142 and the second bar 144 are joined has a stacked shape with overlapping ends, and an elastic body 146 may be placed inside.

[0066] The elastic body 146 according to the first embodiment of the present invention may be provided in the form of a torsion spring, and both ends of the elastic body 146 may be bound to the first bar 142 and the second bar 144, respectively, and may have the property of returning to the initial position in response to torsional stress.

[0067] At this time, the initial position may refer to a state in which the first bar 142 and the second bar 144 are arranged in a straight line, and the upper bar 120 and lower bar 160 are connected to the middle bar 140, and the structure returns to a triangular shape in conjunction with them.

[0068] Here, the elastic body 146 is positioned between the first bar 142 and the second bar 144, and the portions protruding from both ends of the elastic body 146 can be fastened to the first bar 142 and the second bar 144, respectively.

[0069] For this purpose, a fixing groove 1422 for the first elastic body 146 may be formed in the first bar 142, and a fixing groove 1442 for the second elastic body 146 may be formed in the second bar 144. The fixing grooves 1422 and 1442 for the first and second elastic body 146 have the shape of engraved grooves and can correspond to the size and length of both ends of the elastic body 146.

[0070] Furthermore, when the first bar 142 and the second bar 144 are joined, the elastic body 146 can be prevented from separating.

[0071] The connection point where the first bar 142 and the second bar 144 are joined may be such that a rotating projection 1421 formed on the first bar 142 is joined to a groove formed on the second bar 144, and the groove in the second bar 144 may further include an elastic body 146 guide projection 1444 that can fix the position of the body of the elastic body 146 so that it does not rotate together when the first bar 142 and the second bar 144 rotate.

[0072] The elastic body 146 guide projection 1444 has curvature and is formed in a curved shape to contact the elastic body 146, and can restrict the movement of at least one of the ends of the elastic body 146.

[0073] Therefore, the elastic body 146 can move the first bar 142 and the second bar 144 to their initial positions.

[0074] On the other hand, as shown in the figure, grooves may be formed in the first bar 142 and the second bar 144 so as to be recessed in the width direction.

[0075] This may be to provide support force that secures the middle bar 140 to the case so that it stands upright.

[0076] Specifically, the first bar 142 has a first elastic body 146 fixing groove 1422, and the second bar 144 has a second elastic body 146 fixing groove 1442. When fixed to the case, they can be inserted into the upright groove 220 of the case and into the side walls 222 formed on both sides of the case in the width direction from the upright groove 220.

[0077] Through the above configuration, the portable foldable safety triangle warning board of the present invention can be deformed into a triangular shape by having the first bar 142 and the second bar 144 spread out on the elastic body 146, thereby also spreading out the upper bar 120 and the lower bar 160.

[0078] On the other hand, a portable, foldable safety triangle according to a modified embodiment of the present invention may include a stand portion 300.

[0079] Figure 9 is a diagram illustrating the upright portion of a portable foldable safety triangle display board according to a modified embodiment of the present invention, and Figure 10 is a diagram illustrating how the upright portion is bonded to the case portion 200 of a portable foldable safety triangle display board according to a modified embodiment of the present invention.

[0080] As shown in the diagram, it can be confirmed that the stand 300 is positioned between the main body 100 and the case 200.

[0081] The stand portion 300 has the shape of a long, rectangular hexahedron, with its upper part being inserted into the first insertion groove 1423 and the second insertion groove 1443, and its lower part being inserted into the upright groove 220.

[0082] This is for supporting the main body 100 upright, and for this purpose, the lower part of the stand 300 may further include a side cover 320 that can be inserted into the upright groove 220.

[0083] The side cover 320 is formed in a position corresponding to the upright groove 220 and may be formed on both sides along the width direction of the stand portion 300.

[0084] The side cover 320 protrudes from the side of the stand portion 300, and the side wall 222 can be inserted such that a space is formed between the side of the stand portion 300.

[0085] Therefore, the side cover 320 can have a tapered shape on the side of the stand portion 300, where the spacing widens as it goes downwards in the vertical direction, so that the size of the space gradually increases from top to bottom.

[0086] This is because, as the side wall 222 is inserted into the side cover 320, the space gradually narrows, thereby increasing the binding force.

[0087] Furthermore, the stand portion 300 may be formed in a telescopic manner so that its length can increase along the longitudinal direction.

[0088] Furthermore, the stand portion 300 can be detachably bonded to one surface of the stand portion 300 so as to maintain surface contact with the case portion 200.

[0089] For this reason, the stand portion 300 and the case portion 200 may be attached using Velcro® or by magnets.

[0090] For this reason, magnetic material may be incorporated inside the stand portion 300 and the case portion 200.

[0091] [Second Example] The portable foldable safety triangle warning board according to the second embodiment of the present invention has the same configuration as the main body 100, which includes an upper bar 120, a lower bar 160, and a middle bar 140, with the middle bar 140 including a first bar 142 and a second bar 144. Therefore, a detailed explanation of this configuration will be omitted.

[0092] The second embodiment will be explained through Figures 11 to 16.

[0093] Figure 11 is a diagram illustrating a portable foldable safety triangle warning board according to a second embodiment of the present invention; Figure 12 is an exploded view of the portable foldable safety triangle warning board according to a second embodiment of the present invention; Figure 13 is a diagram illustrating the elastic body 146 in the portable foldable safety triangle warning board according to a second embodiment of the present invention; Figure 14 is a diagram illustrating the coupling projection 401, coupling groove 403, and elastic body 146 in the portable foldable safety triangle warning board according to a second embodiment of the present invention; and Figures 15 and 16 are diagrams illustrating the first magnetic body 190 and the second magnetic body 240 in the portable foldable safety triangle warning board according to a second embodiment of the present invention.

[0094] As shown in the diagram, it can be confirmed that connecting grooves 403 are formed at both ends of the upper bar 120, and connecting protrusions 401 are formed at both ends of the lower bar 160 so as to be bound to the connecting grooves 403.

[0095] In this case, the connecting projections 401 of the lower bar 160 can be characterized by protruding from the same plane.

[0096] The first bar 142 and the second bar 144 may each have connecting protrusions 401 and connecting grooves 403 formed at both ends.

[0097] Referring to Figure 12, the upper bar 120 has coupling grooves 403 formed at both ends, and the lower bar 160 has coupling protrusions 401 formed at both ends. The coupling protrusions 401 formed on the lower bar 160 are formed to protrude from the same plane and may consist of a large number of protrusions arranged at regular intervals.

[0098] The coupling protrusions 401 in the second embodiment of the present invention are provided in four portions, each formed by curving at a predetermined angle and spaced apart at regular intervals.

[0099] Furthermore, the connecting protrusions 401 are formed to be of a predetermined length and curved, and are formed symmetrically at opposing positions, with adjacent connecting protrusions 401 being similar.

[0100] Furthermore, the connecting projection 401 has a shape in which its upper end is bent outward. The bent end can be formed into a rounded shape.

[0101] These four connecting protrusions 401 may be arranged in a circular pattern.

[0102] The coupling groove 403, which connects to the coupling projection 401, can be formed as a circular, through-groove. Through this, the coupling projection 401 is fitted into the coupling groove 403, and the end of the coupling projection 401 is formed rounded for smooth insertion, and when inserted, the end is bent outward so that the coupling portion is firmly connected.

[0103] The intermediate bar 140 can consist of a first bar 142 and a second bar 144 that have the same shape as each other.

[0104] Referring to Figure 12, it can be seen that in the portion where the first bar 142 and the second bar 144 are joined, a joining groove 403 is formed on the first bar 142 and a joining projection 401 is formed on the second bar 144.

[0105] The opposite side is formed in a different shape, but at the joint portion of the first bar 142 and the second bar 144, the first bar 142 has a joint groove 403 formed at one end, and the other end has a joint projection 401, while the second bar 144 may have a joint groove 403 formed.

[0106] Through this structure, the other end of the first bar 142 can be connected to the upper bar 120, and the other end of the second bar 144 can be connected to the lower bar 160.

[0107] On the other hand, the elastic body 146 according to the second embodiment of the present invention is formed of three parts and can guide the main body 100 to return to its initial position.

[0108] As shown in Figure 13, it can be confirmed that the elastic body 146 is attached to the joint between the second bar 144 and the lower bar 160, the joint between the second bar 144 and the first bar 142, and the joint between the first bar 142 and the upper bar 120, respectively, along the direction from left to right.

[0109] The elastic body 146 has a shape resembling a wound spring, with one end protruding upward along its longitudinal direction and connected to a bar positioned at the top, and the other end constrained by a bar positioned at the bottom, providing a force that deforms the upper and lower bars into an initial triangular shape when they are unfolded in an overlapping configuration.

[0110] In this configuration, the elastic body 146 may have a projection formed at one end and connected to a bar positioned at the top, while the other end is fixed to a bar positioned at the bottom.

[0111] Specifically, the other end of the elastic body 146 is inserted along the circumference of the connecting projection 401, and at this time, the connecting groove 403 is connected to the connecting projection 401, preventing the elastic body 146 from detaching.

[0112] The upper and lower bars described here can change positions relative to each other, meaning the upper bar can move to the lower bar and the lower bar can move to the upper bar. However, the configuration in which the elastic body 146 is inserted surrounding the connecting projection 401 remains unchanged.

[0113] On the other hand, the portable, foldable safety triangle according to the second embodiment of the present invention may be provided with a magnetic material.

[0114] The case portion 200 may have a magnetic material built inside, be coated with a magnetic substance, or be made of a material that is partially magnetic through double injection molding.

[0115] Furthermore, since the first bar 142 and the second bar 144 also have magnetic material embedded inside, double-extruded, or coated, the first bar 142 and the second bar 144 can be magnetically adhered to one surface of the case portion 200.

[0116] As shown in Figures 15 and 16, a second magnetic material 240 may be formed on a portion of the case portion 200 along its longitudinal direction, and a first magnetic material 190 may be formed on the first bar 142 and the second bar 144, respectively.

[0117] Through this, the first magnetic material 190 of the first bar 142 and the second bar 144 will be bonded to the second magnetic material 240 of the case, allowing the main body 100 to maintain an upright position.

[0118] In this case, the first magnetic material 190 is formed at the bottom when the main body 100 is upright, but may be formed along the width direction of the first bar 142 and the second bar 144 in a portion far from the upper bar 120, and the case portion 200 may be formed on one of two parallel surfaces.
