Technical Field

[0001] This invention relates to the field of traffic auxiliary equipment technology, and in particular to warning signs. Background Technology

[0002] A car warning triangle is a passive reflective material made of plastic. When a driver encounters a sudden breakdown and needs repairs, or is involved in an accident, the reflective properties of the triangle can alert other vehicles to avoid it and prevent secondary accidents. Traditional warning triangles, once installed, may be blown over by fast-moving air currents when approached from the same or opposite side. Summary of the Invention

[0003] The main objective of this invention is to provide a warning sign that reduces the likelihood of it being blown over by rapid air convection.

[0004] To achieve the above objectives, the present invention provides a warning sign, wherein the warning sign comprises:

[0005] Mounting base, including mounting section;

[0006] A mounting frame structure, the bottom of which is rotatably mounted to the mounting portion about a laterally extending axis; and,

[0007] The labeling cloth is arranged longitudinally at intervals from the mounting frame structure. The bottom of the labeling cloth is connected to the mounting part, and the top of the labeling cloth is used to connect to the top of the mounting frame structure. The middle part of the labeling cloth has a hollow area. The labeling cloth is at least partially stretchable and deformable. When the mounting frame structure rotates, the mounting frame structure is used to drive the top of the labeling cloth to move in a direction that can approach and move away from the bottom of the labeling cloth, so that the size of the hollow area is adjustable.

[0008] Optionally, the mounting frame structure has an initial state and a stressed state during its rotational stroke, and the mounting frame structure switches to the stressed state when the top of the mounting frame structure rotates toward the side away from the bottom of the marking cloth;

[0009] The warning sign also includes a first reset component, one end of which is connected to the mounting frame structure and the other end of which is connected to the mounting part. The first reset component is used to provide a reset force when the mounting frame structure is reset to the initial state.

[0010] Optionally, the marking cloth includes two main parts and two elastic telescopic parts, wherein one of the main parts is connected to the mounting part, and the other main part is used to connect to the top of the mounting frame structure, and the two main parts enclose and define the hollow area;

[0011] Each of the main body portions has two ends, and the two ends of one main body portion are respectively connected to the two ends of the other main body portion through two elastic telescopic portions.

[0012] Optionally, the top of the signage cloth is detachably connected to the top of the mounting frame structure, and the warning sign also includes a horizontal bar extending laterally, which is rotatably mounted on the mounting part;

[0013] The bottom of the labeling cloth is fixedly connected to the crossbar, so that the labeling cloth can be rolled up on the crossbar when the crossbar rotates.

[0014] Optionally, the marking cloth has a rolled-up state on the crossbar and an unfolded state. The warning sign also includes a second reset member, one end of which is connected to the crossbar and the other end of which is connected to the mounting part. The second reset member is used to provide a reset force when the marking cloth is reset to the rolled-up state.

[0015] Optionally, the top of the mounting frame structure is provided with a mounting hole, and the top of the marking cloth is provided with a buckle for holding it in the mounting hole.

[0016] Optionally, the mounting part includes two mounting plates spaced apart in the lateral direction. The two mounting plates have two first mounting holes and two second mounting holes arranged opposite each other in the lateral direction. The two first mounting holes and the two second mounting holes are spaced apart in the longitudinal direction.

[0017] The mounting frame structure includes two connecting shafts that both extend laterally, and the two connecting shafts are respectively rotatably mounted in the two first mounting holes.

[0018] The two ends of the crossbar are respectively rotatably mounted in the two second mounting holes.

[0019] Optionally, the mounting frame structure includes a horizontally extending fixed rod and two movable rods. The fixed rod is connected to the mounting part. The bottoms of the two movable rods are rotatably mounted on the two ends of the fixed rod around a longitudinally extending rotation axis. One of the tops of the two movable rods is provided with a socket, and the other is provided with a pin that mates with the socket.

[0020] Optionally, the warning sign further includes a first bracket and a second bracket, both extending laterally. The middle part of the first bracket is rotatably mounted on the middle part of the second bracket about a vertically extending axis of rotation. The first bracket is positioned above the second bracket, and the mounting base is provided on the first bracket.

[0021] Optionally, the marking fabric includes reflective fabric; and / or,

[0022] The mounting frame structure is made of a reflective material.

[0023] In the technical solution provided by this invention, the bottom of the mounting frame structure is rotatably mounted to the mounting part around a laterally extending axis. The top of the mounting frame structure swings around its bottom. The bottom of the marking cloth is connected to the mounting part, and the top of the marking cloth is connected to the top of the mounting frame structure. Because the marking cloth and the mounting frame structure are spaced apart in the longitudinal direction, and the marking cloth is at least partially stretchable and deformable, when the top of the mounting frame structure rotates around its bottom, the top of the mounting frame structure pulls the top of the marking cloth towards or away from the bottom of the marking cloth. When the airflow suddenly increases, the marking cloth and the mounting frame structure are affected by the airflow. The top of the mounting frame structure moves with the wind direction, and the mounting frame structure tilts, thereby causing the top of the marking cloth to move away from the bottom of the marking cloth. During the deformation of the marking cloth under force, the hollow area increases synchronously, increasing the wind passage area, thereby reducing the possibility of the triangular warning sign being blown over.

[0040] A car warning triangle is a passive reflective material made of plastic. When a driver encounters a sudden breakdown and needs repairs, or is involved in an accident, the reflective properties of the triangle can alert other vehicles to avoid it and prevent secondary accidents. Traditional warning triangles, once installed, may be blown over by fast-moving air currents when approached from the same or opposite side.

[0041] To address the above problems, the present invention provides a warning sign. Figure 1 A perspective view of an embodiment of the warning sign provided by the present invention in a folded state; Figure 2 for Figure 1 A three-dimensional schematic diagram of the warning sign when the mounting frame structure is in its initial state; Figure 3 for Figure 2 A three-dimensional schematic diagram of the warning sign when the mounting frame structure is under stress; Figure 4 for Figure 2 A side view; Figure 5 for Figure 3 A side view; Figure 6 for Figure 1 A front view of the warning sign; Figure 7 for Figure 6 Enlarged view of point A in the middle; Figure 8 for Figure 6 An enlarged view of point A from another perspective; Figure 9 for Figure 1 Exploded view of the mounting frame structure.

[0042] Please see Figures 1 to 5 The warning sign 100 includes a mounting base 1, a mounting frame structure 2, and a sign cloth 3. The mounting base 1 includes a mounting part 11. The bottom of the mounting frame structure 2 is rotatably mounted on the mounting part 11 about a horizontally extending axis. The sign cloth 3 is spaced apart from the mounting frame structure 2 in the longitudinal direction. The bottom of the sign cloth 3 is connected to the mounting part 11, and the top of the sign cloth 3 is used to connect to the top of the mounting frame structure 2. The middle part of the sign cloth 3 has a hollow area 3a. The sign cloth 3 is at least partially stretchable and deformable. When the mounting frame structure 2 rotates, the mounting frame structure 2 is used to drive the top of the sign cloth 3 to move in a direction that can approach and move away from the bottom of the sign cloth 3, so that the size of the hollow area 3a is adjustable.

[0043] It should be noted that, under normal use, the mounting base 1 is placed on a horizontal surface, and the mounting frame structure 2 is set to a near-vertical state. The mounting frame structure 2 maintains a vertical state, which can be achieved through rotational damping friction with the mounting part 11, through the tension of the marking cloth 3, or through the clamping of a torsion spring. Of course, the method of vertical positioning of the mounting frame structure 2 is not limited to the above examples. Those skilled in the art may make other changes based on the technical essence of the embodiments in this specification, but as long as the function and effect achieved are the same as or similar to those in the embodiments of this specification, they should be covered within the protection scope of the embodiments of this specification.

[0044] It is understandable that, since the marking cloth 3 and the mounting frame structure 2 are arranged at intervals in the longitudinal direction, in the initial state, when viewed from the side, the marking cloth 3, the mounting frame structure 2 and the mounting base 1 are arranged in a near right-angled triangle. When the top of the mounting frame structure 2 rotates around its bottom, the right-angled triangle structure will gradually become an obtuse triangle, and the marking cloth 3 will be stretched, thereby making the hollow area 3a larger.

[0045] In the technical solution provided by this invention, the bottom of the mounting frame structure 2 is rotatably mounted to the mounting part 11 around a laterally extending axis. The top of the mounting frame structure 2 swings around its bottom. The bottom of the marking cloth 3 is connected to the mounting part 11, and the top of the marking cloth 3 is connected to the top of the mounting frame structure 2. Because the marking cloth 3 and the mounting frame structure 2 are spaced apart in the longitudinal direction, and the marking cloth 3 is at least partially stretchable and deformable, when the top of the mounting frame structure 2 rotates around its bottom, the top of the mounting frame structure 2 will be pulled... When the top of the signage cloth 3 moves towards or away from the bottom of the signage cloth 3, and the airflow suddenly increases, the signage cloth 3 and the mounting frame structure 2 are affected by the airflow. The top of the mounting frame structure 2 moves with the wind direction and tilts, thereby causing the top of the signage cloth 3 to move away from the bottom of the signage cloth 3. During the deformation of the signage cloth 3 under force, the hollow area 3a will increase synchronously, and the air passage area will increase, thereby reducing the possibility of the triangular warning sign 100 being blown over.

[0046] Furthermore, in this embodiment, the mounting frame structure 2 has an initial state and a stressed state during its rotation stroke. When the top of the mounting frame structure 2 rotates toward the side away from the bottom of the marking cloth 3, the mounting frame structure 2 switches to the stressed state. The warning sign 100 also includes a first reset member 4, one end of which is connected to the mounting frame structure 2 and the other end is connected to the mounting part 11. The first reset member 4 is used to provide a reset force when the mounting frame structure 2 is reset to the initial state.

[0047] It is understood that in the initial state, i.e., the vertical state referred to in the above description, the force state refers to the state in which the mounting frame structure 2 is tilted when subjected to strong winds. The first reset member 4 can be a torsion spring, tension spring, etc., which enables the mounting frame structure 2 to be subjected to a balanced elastic force and maintain a stable initial state. By setting the first reset member 4, when the warning sign 100 is in a suddenly increased airflow, the first reset member 4 accumulates elastic potential energy, and when the airflow decreases, the first reset member 4 can release the elastic potential energy, restoring the mounting frame structure 2 to the initial state, achieving the initial equilibrium state.

[0048] In this embodiment, the marking cloth 3 includes two main body parts 31 and two elastic telescopic parts 32. One main body part 31 is connected to the mounting part 11, and the other main body part 31 is connected to the top of the mounting frame structure 2. The two main body parts 31 enclose and define the hollow area 3a. Each main body part 31 has two ends, and the two ends of one main body part 31 are respectively connected to the two ends of the other main body part 31 through the two elastic telescopic parts 32. With this configuration, when the main body part 31 connected to the top of the mounting frame structure 2 swings with the top of the mounting frame structure 2, it gradually moves away from the main body part 31 connected to the mounting part 11. The two elastic telescopic parts 32 are stretched by tension, and the hollow area 3a defined by the two main body parts 31 can become larger. When the external force decreases or even disappears, the two elastic telescopic parts 32 restore their deformation, thereby driving the mounting frame structure 2 to return to the initial state. At this time, the two main body parts 31 move closer to each other, and the area of ​​the hollow area 3a becomes smaller. Preferably, the marking cloth 3 is arranged symmetrically along the vertical line, and the two elastic telescopic parts 32 are also arranged symmetrically, so that the marking cloth 3 can deform symmetrically and synchronously when it deforms.

[0049] In this embodiment, the top of the label cloth 3 is detachably connected to the top of the mounting frame structure 2. The warning sign 100 also includes a horizontally extending crossbar 5, which is rotatably mounted on the mounting part 11. The bottom of the label cloth 3 is fixedly connected to the crossbar 5, allowing the label cloth 3 to be rolled up on the crossbar 5 when the crossbar 5 is rotated. This arrangement allows the top of the label cloth 3 to be detached from the top of the mounting frame structure 2 during storage, and then the crossbar 5 can be rotated to allow the label cloth 3 to be wound and rolled up on the crossbar 5. This avoids the label cloth 3 being exposed inside or outside the storage box when not properly folded.

[0050] In this embodiment, the marking cloth 3 has a wound state where it is rolled up on the crossbar 5 and an unfolded state where it is extended. The warning sign 100 also includes a second reset member 6, one end of which is connected to the crossbar 5 and the other end of which is connected to the mounting part 11. The second reset member 6 is used to provide a reset force when the marking cloth 3 is reset to the wound state. The second reset member 6 can also be a torsion spring, a coil spring, etc. In this way, when the top of the marking cloth 3 is fixed to the top of the mounting frame structure 2, the marking cloth 3 wrapped around the crossbar 5 can be pulled to extend the marking cloth 3. At the same time, the crossbar 5 rotates, causing one end of the second reset member 6 to rotate. The second reset member 6 deforms and stores elastic potential energy. When the top of the marking cloth 3 is removed from the top of the mounting frame structure 2, the second reset member 6 releases the elastic potential energy, restores its deformation, and drives the crossbar 5 to rotate, thereby realizing the automatic winding of the marking cloth 3. This ensures that the label cloth is folded neatly, solving the problems of inconvenient storage and easy leakage and tearing, and greatly improving storage efficiency.

[0051] In this embodiment, the top of the mounting frame structure 2 is provided with a mounting hole 2a, and the top of the marking cloth 3 is provided with a buckle 33 for engaging with the mounting hole 2a. Thus, disassembly can be achieved by engaging the mounting hole 2a with the buckle 33, which is convenient to operate and manufacture. Of course, the disassembly method between the mounting frame structure 2 and the marking cloth 3 can also be set in other possible forms, which can be determined according to the actual situation. This embodiment does not limit this aspect.

[0052] Specifically, in this embodiment, the mounting part 11 includes two mounting plates 111 spaced apart in the transverse direction. The two mounting plates 111 have two first mounting holes 111a and two second mounting holes 111b arranged opposite each other in the transverse direction. The two first mounting holes 111a and the two second mounting holes 111b are spaced apart in the longitudinal direction. The mounting frame structure 2 includes two connecting shafts extending laterally, each rotatably mounted in one of the two first mounting holes 111a. The two ends of the crossbar 5 are rotatably mounted in one of the two second mounting holes 111b. Thus, the mounting frame structure 2 is rotatably connected to the two mounting plates 111 via the two connecting shafts, and the marking cloth 3 is rotatably mounted on the two mounting plates 111 via the crossbar 5. It is understood that the longitudinal distance between the crossbar 5 and the mounting frame structure 2 is set to be greater than the total thickness of the marking cloth 3 after it is wound onto the crossbar 5, to facilitate the winding and unwinding of the marking cloth 3.

[0053] In this embodiment, the mounting frame structure 2 includes a horizontally extending fixed rod 21 and two movable rods 22. The fixed rod 21 is connected to the mounting part 11. The bottoms of the two movable rods 22 are rotatably mounted on the two ends of the fixed rod 21 around a longitudinally extending rotation axis. One of the tops of the two movable rods 22 is provided with an insertion hole, and the other is provided with a pin 221 that cooperates with the insertion hole. With this configuration, when the mounting frame structure 2 needs to be assembled, the two movable rods 22 can be rotated around their bottoms, and the tops of the two movable rods 22 can be moved towards each other. Then, the pin 221 is inserted into the insertion hole, thereby forming a triangular structure. When folding and storing, the pin 221 can be pulled out of the insertion hole, and then both movable rods 22 can be rotated towards the center, so that the two movable rods 22 switch to a horizontally extending state and are arranged longitudinally in sequence with the fixed rod 21. Simultaneously, the marking cloth 3 can be rolled up onto the crossbar 5.

[0054] In this embodiment, the warning sign 100 further includes a first bracket 7 and a second bracket 8, both extending laterally. The middle portion of the first bracket 7 is rotatably mounted on the middle portion of the second bracket 8 around a vertically extending rotation axis. The first bracket 7 is positioned above the second bracket 8, and the mounting base 1 is provided on the first bracket 7. In the storage state, the first bracket 7, the second bracket 8, the fixed rod 21, the two movable rods 22, and the crossbar 5 all extend laterally, facilitating storage in a storage box. When needed, the first bracket 7 can be rotated 90° relative to the second bracket 8, causing the first bracket 7 and the second bracket 8 to intersect and form a stable base.

[0055] To make the warning sign 100 more easily visible to other drivers and reduce the risk of traffic accidents, in this embodiment, the signage cloth 3 includes reflective cloth; and / or, the mounting frame structure 2 is made of reflective material. It is understood that, to achieve reflectivity, the mounting frame structure 2 may also have a reflective film layer or reflective material adhered to its surface, etc. The specific design can be tailored to the actual situation, and this embodiment does not limit this.

[0056] When using the warning sign 100, first take the folded and stored warning sign 100 out of the storage box, rotate the two movable rods 22 around their bottoms, move the tops of the two movable rods 22 toward each other, insert the pin 221 into the insertion hole, and then pull the top of the marking cloth 3 rolled up on the crossbar 5 upwards, so that the marking cloth 3 is extended, and then install the buckle 33 at the top of the marking cloth 3 into the mounting hole. After assembly, rotate the second bracket 8 90° relative to the first bracket 7, so that the first bracket 7 extends laterally and the second bracket 8 extends longitudinally. The support points at both ends of the first bracket 7 and the support points at both ends of the second bracket 8 form a stable base, so that the first bracket 7 and the second bracket 8 can be placed on the ground. It should be noted that when one side of the signage cloth 3 is positioned on the windward side, the mounting frame structure 2 will rotate around the connecting shaft when the warning sign 100 is subjected to wind force. The top of the mounting frame will move with the wind direction, and the mounting frame structure 2 will tilt, thereby causing the top of the signage cloth 3 to move away from the bottom of the signage cloth 3. The two elastic telescopic parts 32 will deform. During the deformation of the signage cloth 3 under force, the hollow area 3a will increase simultaneously, thereby increasing the wind passage area of ​​the hollow area 3a and reducing the possibility of the warning sign 100 being blown over by strong winds.

[0057] When the wind force decreases or disappears, the two elastic expansion parts 32 restore their deformation, thereby driving the mounting frame structure 2 to return to the initial state, and the area of ​​the hollow area 3a returns to the initial state.

[0058] When storage is required, the buckles 33 on the label cloth 3 can be removed from the mounting holes on the mounting frame structure 2, and the label cloth 3 can be automatically rolled up onto the crossbar 5 by the second reset member 6; then, the pin 221 can be pulled out from the insertion hole, and then both movable rods 22 can be rotated toward the center, so that the two movable rods 22 can be switched to the lateral extension state, so that the two movable rods 22 and the fixed rod 21 can be arranged in sequence in the longitudinal direction; finally, the first bracket 7 can be rotated 90°, so that the first bracket 7 and the second bracket 8 can be arranged in parallel in the lateral direction, thereby completing the folding and storage.

[0059] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
