DETAILED DESCRIPTION
Please refer to FIGS. 1-5, one of the preferred embodiments of the safety warning device 100 of the present invention includes a base 10, a counterweight block 20, and a telescopic warning body 30.
Please refer to FIGS. 1-4, the base 10 has a base plate 11 and a connecting ring seat 12. The base plate 11 is a chamfered square-shaped plate having a bottom surface 111 and a top surface 112 opposite to the bottom surface 111. The bottom surface 111 can be steadily placed on the ground (or flat surface). The connecting ring seat 12 is a round-shaped ring, which is integrally disposed on the top surface 112 of the base plate 11. Thus, an accommodating space 13 with a hollow top is formed by surrounding of the connecting ring seat 12 and the top surface 112 of the base plate 11. An outer periphery of the connecting ring seat 12 concavely forms a connecting ring trough 121 and an inserting trough 122 communicating the connecting ring trough 121 and a top surface of the connecting ring seat 12. The inserting trough 122 inclinedly corresponds to an axle of the connecting ring seat 12.
Please refer to FIGS. 1-4, the counterweight block 20 has a predetermined weight, and the outer profile of the counterweight 20 is identical to the outer profile of the accommodating space 13 of the base 10. The counterweight block 20 is made of metal, stone powder, or sand.
Please refer to FIGS. 1-4, the telescopic warning body 30 is integrally formed as a flexible bellows-shaped tube, which is in conical shape. The telescopic warning body 30 can be compressed or elongated by an external force. When an external force is applied, the telescopic warning body 30 can be compressed; when the external force is released, the telescopic warning body 30 will be back to the original condition. The telescopic warning body 30 has a bottom end 31, a top end 32, and a bellows section 33 connected between the bottom end 31 and the top end 32. The outer diameter of the bottom end 31 is larger than that of the top end 32. The outer diameter of the bellows section 33 at the bottom end 31 eventually narrows down toward the top end 32. A connecting flange 311 is formed at the bottom end 31 toward an axle of the telescopic warning body 30. A through hole 321 communicating outside and inside is formed at the center of the top end 32.
The aforementioned is the first preferred embodiment of the safety warning device 100 according to the present invention. The detailed assembling method and the way of using are described below.
When a user wants to use the safety warning device 100, a counterweight block 20 is steadily disposed inside the accommodating space 13 of the base 10, and then the connecting flange 311 on the bottom end 31 of the telescopic warning body 30 slides along the inserting trough 122 of the base 10 into the connecting ring trough 121 and rotates a circle along the connecting ring trough 121. Thus, the connecting flange 311 of the telescopic warning body 30 can be connected to the connecting ring trough 121 of the base 10 (as shown in FIG. 4) to complete the assembling process of the exemplary embodiment of the present invention.
Since the telescopic warning body 30 has a flexible bellows-shaped tube, when storing the safety warning device 100, the user can press the top end 32 to compress the volume of the telescopic warning body 30. The top end 32 will move toward the bottom end 31 to compress the bellows section 33, and the height of the bellows section 33 will decrease (as shown in FIG. 5A), thereby largely reducing the volume of the telescopic warning body 30 and saving storage space, as well as making moving more easy. Besides, the telescopic warning body 30 is flexible and can be distorted and restored to the original shape under an external force (as shown in FIG. 5B). Thus, the telescopic warning body 30 is not easy to get damaged when being hit, which can further prolong the usage life. Due to the flexible characteristic, the telescopic warning body 30 can minimize the damage and injury of the vehicles and the pedestrians when the vehicles or the pedestrians hit the telescopic warning body 30, thereby achieving the goals of small storage volume, easy moving, long usage life, and superior safety. Moreover, because of having the features of being able to be compressed under force, lateral side distortion and restoration ability, the telescopic warning body 30 can be used in the in-line skates, skateboard, or other exercises to prevent the user from being injured.
Besides, a reflective layer (not shown in the FIGS.) can be applied to the outer periphery of the bellows section 33 of the telescopic warning body 30. The reflective layer can be a reflective paint or a reflective sticker, which can enhance the recognition and provide safer warning effect.
The FIG. 11 provides a front view of the telescopic warning body 30 of the preferred embodiment of the present invention. The structure and function of the telescopic warning body 30 as shown in FIG. 11 is the same as the previous embodiment. The differences lie in that the outer shape and size. The embodiment shown in FIG. 11 is a flatter type of telescopic warning body 30.
Moreover, even though the telescopic warning body 30 in the previous embodiment is formed as conical shape, the telescopic warning body 30 can also form as other shapes, such as cylindrical shape (as shown in FIG. 10), which means the outer diameter of the bottom end is identical to the outer diameter of the top end, and the same compression effect can also be achieved.
Furthermore, even though the telescopic function of the telescopic warning body 30 is achieved by serially connecting multiple unit structures, which means each unit structure at least includes two rings with different diameters and two side walls connecting the two rings, the telescopic function of the telescopic warning body 30 can actually be achieved by utilizing continuous spiral structures, which means two spiral strings with different diameters and a wall provided between the two spiral strings can have the same compression effect. The structure can also be a combination of the aforementioned two structures, which means a combination of a multi-unit structure and a spiral structure.
Please refer to FIGS. 6-9, which is a second preferred embodiment of a safety warning device 200. The safety warning device 200 not only has a base 10, a counterweight block 20, and a telescopic warning body 30 which are the same as the first preferred embodiment, but also includes an elongated connecting ring 40 and an elongated telescopic warning body 50.
The structure of the base 10, the counterweight 20, and the telescopic warning body 30 of the second embodiment is the same as the first embodiment.
Please refer to FIGS. 6-9, the elongated connecting ring 40 is an integrally formed round-shaped ring, which can define a bottom connecting part 41, a top connecting part 42, and a middle connecting part 43 connecting the bottom connecting part 41 and the top connecting part 42. The outer diameter of the middle connecting part is larger than that of the bottom connecting part 41 and the top connecting part 42. An outer periphery of the bottom connecting part 41 is concavely formed with a bottom connecting ring trough 411 and a bottom inserting trough 412 communicating the bottom connecting ring trough 411 and one end of the elongated connecting ring 40. The bottom inserting trough 412 is inclinedly corresponding to an axle of the elongated connecting ring 40. An outer periphery of the top connecting part 42 is concavely formed with a top connecting ring trough 421 and a top inserting trough 422 communicating the top connecting ring trough 421 and another end of the elongated connecting ring 40. The top inserting trough 422 is inclinedly corresponding to an axle of the elongated connecting ring 40.
Please refer to FIGS. 6-9, the elongated telescopic warning body 50 is integrally formed as a flexible bellows-shaped tube, which is in conical shape. The elongated telescopic warning body 50 has an elongated bottom end 51, an elongated top end 52, and an elongated bellows section 53 connected between the elongated bottom end 51 and the elongated top end 52. The outer diameter of the elongated bottom end 51 is larger than that of the elongated top end 52. The outer diameter of the elongated bellows section 53 at the elongated bottom end 51 eventually narrows down toward the elongated top end 52. A bottom connecting flange 511 is formed at the elongated bottom end 51 toward an axle of the elongated telescopic warning body 50. A through hole 521 communicating outside and inside is formed at the center of the elongated top end 52.
Please refer to FIG. 8, in the present embodiment, a top connecting flange 322 is formed at the top end 32 toward an axle of the telescopic warning body 30.
The aforementioned is the second preferred embodiment of the safety warning device 200 according to the present invention. The detailed assembling method and the way of using are described below.
First, assemble the base 10, the counterweight block 20, and the telescopic warning body 30 in a same manner as the first embodiment. And then, the top connecting flange 322 on the top end 32 of the telescopic warning body 30 slides along the bottom inserting trough 412 of the elongated connecting ring 40 (as shown in FIG. 8) into the bottom connecting ring trough 411 and rotates a circle along the bottom connecting ring trough 411, so as to connect the top connecting flange 322 of the telescopic warning body 30 to the bottom connecting ring trough 411 of the elongated connecting ring 40 (as shown in FIG. 9). The bottom connecting flange 511 on the elongated bottom end 51 of the elongated telescopic warning body 50 slides along the top inserting trough 422 of the elongated connecting ring 40 (as shown in FIG. 8) into the top connecting ring trough 421 and rotates a circle along the top connecting ring trough 421, so as to connect the bottom connecting flange 511 of the elongated telescopic warning body 50 to the top connecting ring trough 421 of the elongated connecting ring 40 (as shown in FIG. 9).
By the aforementioned arrangement, the present embodiment not only has the same function as the previous embodiment, but also extends the height of the safety warning device by combining the telescopic warning body 30, the elongated connecting ring 40, and the elongated telescopic warning body 50, and the diverse application of the safety warning device of the present embodiment can be achieved.
Besides, a reflective layer (not shown in the FIGS.) can be applied to the outer peripheries of the elongated bellows section 53 of the elongated telescopic warning body 50 and the middle connecting part 43 of the elongated connecting ring 40. The reflective layer can be a reflective paint or a reflective sticker, which can enhance the recognition and provide safer warning effect.
Moreover, even though the elongated telescopic warning body 50 in the previous embodiment is formed as conical shape, the elongated telescopic warning body 50 can also form as cylindrical shape, which means the outer diameter of the elongated bottom end is identical to the outer diameter of the elongated top end, and the same compression effect can also be achieved.
Furthermore, even though the telescopic function of the elongated telescopic warning body 50 is achieved by serially connecting multiple unit structures, which means each unit structure at least includes two rings with different diameters and two side walls connecting the two rings, the telescopic function of the elongated telescopic warning body 50 can actually be achieved by utilizing continuous spiral structures, which means two spiral strings with different diameters and a wall provided between the two spiral strings can also have the same compression effect. The structure can also be a combination of the aforementioned two structures, which means a combination of a multi-unit structure and a spiral structure.
Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof.
