Description

Technical Field

[0001] The present invention relates to a safety device for tires, and particularly to a run - flat device that is installed inside a tire to support the tread.

Background Art

[0002] When a vehicle is traveling on the road and a tire is punctured by a sharp object, or damaged due to a defect in the tire itself or external forces in the environment, a gap may occur in the tire and air may leak out, causing the tire to be unable to maintain a pressurized state. The tread portion of the tire may sink, the tire diameter may rapidly decrease, and the tire may become unable to rotate normally, making the vehicle prone to getting out of control and even damaging the wheel rim.

[0003] To solve the problem of vehicle out - of - control due to air leakage in the above - mentioned tire, tire manufacturers have invented tires with enhanced sidewall strength. This enables the tire to maintain a certain supporting force even after being punctured, allowing the tire to continue rotating and the vehicle to keep running. Such tires with enhanced sidewalls have the advantage of being able to continue running after being punctured, but they have the disadvantages of being more expensive than ordinary tires and having a poorer ride comfort due to their hard tire structure. Therefore, there is still a need in the market to replace this type of tire.

Summary of the Invention

Problems to be Solved by the Invention

[0004] In view of this, the purpose of the present invention is to design and provide a device that can be installed on a tire and support the tread portion when the tire is damaged and loses internal pressure, enabling the tire to continue rotating and thus avoiding vehicle out - of - control for users.

Means for Solving the Problems

[0005] To achieve the above objective, the present invention provides an explosive tube continuing device comprising a plurality of support elements, a bundle ring that arranges and fixes these support elements in an annular shape along the axis of rotation, a steel cable ring and an elastic ring, wherein two opposing directions along the axis of rotation are defined as the first direction and the second direction, each of the support elements having a main wall, a hooking portion connected to the side of the main wall far from the axis of rotation, the hooking portion having a suspension end protruding in the first direction, a bundle ring groove formed in the portion of the hooking portion adjacent to the suspension end, an outer wall, an inner wall and a middle wall connected to the side of the main wall far from and near the axis of rotation, and the portion in between, respectively, the outer wall, the inner wall and the middle wall each protruding in the second direction, a shielding wall connected between the outer wall and the inner wall, and a support surface formed between the main wall and the outer wall.

[0006] Steel cable through-holes are formed between the main wall, the inner wall, the middle wall, and the shielding wall; elastic ring through-holes are formed between the main wall, the outer wall, the middle wall, and the shielding wall; an insertion opening is formed in the portion of the shielding wall corresponding to the elastic ring through-hole; the insertion opening penetrates the shielding wall along the rotational direction of the rotational axis; the length of the insertion opening perpendicular to the rotational axis is shorter than the length of the elastic ring through-hole perpendicular to the rotational axis; the bundle ring is an elastic body and is tightly fitted into the bundle ring groove of the support element; the steel cable ring passes through the steel cable through-hole of the support element; the elastic ring is fitted through the elastic ring through-hole of the support element and is an elastic body that can pass through the insertion opening of the support element after being compressed and deformed by an external force.

[0007] When using the present invention, the explosive tire extension device is fixed to the inside of the tire wall by engaging the hooking portion of each support element with the main wall and hooking it onto a convex ring formed on the inside of the tire wall. At this time, a certain distance is provided between the support surface of each support element of the explosive tire extension device and the tread surface of the tire. Therefore, when the tire is used normally, even if the tread surface is temporarily deformed by stepping on an object, the tread surface will not come into contact with the explosive tire extension device.

[0008] According to the present invention, when a tire punctures and loses internal pressure, causing the tread surface to collapse inward, the support elements are constrained by bundle rings, steel cable rings, and elastic rings and arranged in a ring shape. Furthermore, the support elements can be arranged in pairs in close proximity, so that the support surfaces of each support element fixed to the inside of the tire wall can support the tread surface. As a result, the tire can maintain a constant shape and continue to rotate, preventing the vehicle from becoming uncontrollable. Moreover, the tire propulsion device provides support to the tire that has lost internal pressure, allowing the vehicle to be safely moved to the shoulder of the road and stopped to await assistance, or to continue driving to the nearest repair shop.

[0010] To explain the present invention more clearly, preferred embodiments are given below and described in detail with reference to the drawings. As shown in Figures 1 to 5, an explosive tire extension device 100 according to one embodiment of the present invention is for mounting on a tire and comprises a plurality of support elements 10, a bundle ring 20 that arranges and fixes these support elements 10 in an annular shape along the rotation axis L, a steel cable ring 30, and an elastic ring 40. Furthermore, two opposing directions along the rotation axis L are defined as the first direction L1 and the second direction L2.

[0011] The multiple support elements 10 consist of 30 support elements 10, each support element 10 being made of polyvinyl chloride, commonly known as plastic steel, and curved in an arc shape. In other preferred embodiments, the multiple support elements 10 may include two or more other numbers of support elements 10, and each support element 10 may be made of a material such as aluminum alloy, carbon fiber, or glass fiber. These support elements 10 are arranged adjacent to each other, and each support element 10 has a main wall 12. The main wall 12 is an arc-shaped plate, and a latching portion 14 is connected to the side farther from the rotation axis L. The latching portion 14 protrudes in the first direction L1 and has a suspension end 141. A bundle ring groove 142 is formed in the portion of the latching portion 14 adjacent to the suspension end 141. The latching portions 14 of these support elements 10 are arranged in an annular shape around the rotation axis L, and similarly, the bundle ring grooves 142 of these support elements 10 are also arranged in an annular shape around the rotation axis L.

[0012] As shown in Figures 2 to 4 and Figures 7 and 8, an outer wall 16 and an inner wall 18 are connected to the side of the main wall 12 that is far from the rotation axis L and the side that is close to it, respectively, and an intermediate wall 11 is connected to the portion of the main wall 12 between the outer wall 16 and the inner wall 18. The outer wall 16, inner wall 18 and intermediate wall 11 of these support elements 10 are each arranged in an annular shape around the rotation axis L. The outer wall 16, inner wall 18 and intermediate wall 11 are plate bodies that protrude from the main wall 12 in a second direction L2, and a shielding wall 13 is connected between the outer wall 16 and the inner wall 18, and this shielding wall 13 is also connected to the intermediate wall 11. Steel cable through holes 15 are formed between the main wall 12, inner wall 18, intermediate wall 11 and shielding wall 13, and elastic ring through holes 17 are formed between the main wall 12, outer wall 16, intermediate wall 11 and shielding wall 13.

[0013] The steel cable through-holes 15 of these support elements 10 are arranged in an annular shape around the rotation axis L. The elastic ring through-holes 17 of these support elements 10 are also arranged in an annular shape around the rotation axis L. An opening 131 is formed in the part of the shield wall 13 corresponding to the elastic ring through-hole 17. This opening 131 penetrates the shield wall 13 along the rotational direction of the rotation axis L, and the length of the opening 131 perpendicular to the rotation axis L is shorter than the length of the elastic ring through-hole 17 perpendicular to the rotation axis L.

[0014] Both ends of the arrangement opening 131 along the rotational direction of the rotational axis L are enlarged to form a first semi-enlarged area 132 and a second semi-enlarged area 133. Of two adjacent support elements 10, the first semi-enlarged area 132 of one support element 10 faces the second semi-enlarged area 133 of the other support element 10, and multiple pairs of first semi-enlarged areas 132 and second semi-enlarged areas 133 exist between the support elements 10. In this embodiment, the first semi-enlarged area 132 communicates not only with the elastic ring through hole 17, but also with both the steel cable through hole 15 and the elastic ring through hole 17. Similarly, the second semi-enlarged area 133 communicates not only with the elastic ring through hole 17, but also with both the steel cable through hole 15 and the elastic ring through hole 17.

[0015] As shown in FIGS. 2, 3 and 4, a support surface F is formed on the surface of the main wall 12 and the outer wall 16 of each support element 10 that is far from the rotation axis L. Each support element 10 has a first end face F1 and a second end face F2 at both ends along the rotation direction of the rotation axis L. On the far side and the near side of the first end face F1 from the rotation axis L, a first convex portion 191 and a second convex portion 192 are respectively formed, and the first convex portion 191 and the second convex portion 192 protrude from the first end face F1. Specifically, the diameter of the first convex portion 191 is larger than the diameter of the second convex portion 192, each first convex portion 191 is located at the portion where the main wall 12 is connected to the latching portion 14 and the outer wall 16, and each second convex portion 192 is located at the portion where the main wall 12 is connected to the middle wall 11. Further, a jack hole 193 is formed in the first convex portion 191. Furthermore, as shown in FIGS. 9 and 10, an adjustment member 19 can be selectively inserted into the jack hole 193. The adjustment member 19 is an elastic body, and when inserted into the jack hole 193, the adjustment member 19 protrudes from the first convex portion 191.

[0016] In a normal case, among two adjacent support elements 10, the first convex portion 191 and the second convex portion 192 of one support element 10 abut against the second end face F2 of the other support element 10. When the gap between adjacent support elements 10 is too large, the adjustment member 19 can be inserted into the jack hole 193 of one support element 10. Then, by making the adjustment member 19 cooperate with the second convex portion 192 to abut against the second end face F2 of the other support element 10, the gap between adjacent support elements 10 can be filled, and these support elements 10 can be arranged more closely.

[0017] As shown in FIGS. 1 to 4, the binding ring 20 is an annular elastic body and is tightly annularly installed in the binding ring groove 142 of the support element 10. Due to the restoring force of the binding ring 20, the binding ring 20 can restrain the support elements 10 to be arranged in a state where two support elements 10 are close to each other. That is, as described above, the first convex portion 191 and the second convex portion 192 of one support element 10 among two adjacent support elements 10 abut against the second end face F2 of the other support element 10.

[0018] As shown in Figures 2A and 7 to 8B, the steel cable ring 30 includes a steel cable 32 and a steel cable adjustment member 34. The steel cable 32 passes through the steel cable through hole 15 of the support element 10, and sleeves 321 are connected to both ends of the steel cable 32. Each sleeve 321 is provided with a screw hole 322, which is formed coaxially with the sleeve 321. A positioning screw hole 323 is provided around each sleeve 321, and each positioning screw hole 323 communicates with one side of the circumference of the screw hole 322. A positioning bolt 324 is screwed into each positioning screw hole 323. The steel cable adjustment member 34 has a rotating part 341, which in this embodiment is a polygonal column. Threaded rods 342 are provided at both ends of the rotating part 341, and the threads of these two threaded rods 342 are in opposite directions. Each screw rod 342 is screwed into a screw hole 322 in the sleeve 321, and one side of each screw rod 342 is held in place by a positioning bolt 324, thereby fixing the position of each screw rod 342 with the positioning bolt 324. The rotating part 341 is exposed to the outside from a pair of opposing first semi-enlarged sections 132 and second semi-enlarged sections 133. This allows the user to operate the cable adjustment member 34 by rotating the rotating part 341 after loosening the positioning bolt 324, thereby tightening or loosening the cable 32. After adjustment by rotating the cable adjustment member 34 is complete, the user tightens the positioning bolt 324 again to fix the circumference length of the cable ring 30 and prevent the tension of the cable 32 from loosening. When the steel cable adjustment member 34 tightens the steel cable 32, the steel cable 32 comes into close contact with the inner wall of the steel cable through hole 15, and the steel cable 32 is restrained so that the support elements 10 are positioned close together in pairs.

[0019] As shown in Figures 2A, 4, 5, and 7, the elastic ring 40 is made of an elastic material such as rubber or plastic that can return to its original shape even after being compressed by an external force and deformed. The elastic ring 40 is fitted through the elastic ring through-hole 17 of the support element 10. Since the elastic ring 40 can pass through the placement opening 131 of the support element 10 after being compressed and deformed by an external force, the elastic ring 40 can be inserted into the elastic ring through-hole 17 of the support element 10 via the placement opening 131, or removed outward from the elastic ring through-hole 17. This allows the elastic ring 40 to restrain the support elements 10 in a state where they are lined up in pairs.

[0020] When using the above-described preferred embodiment of the present invention, the explosive tire extension device 100 is mounted on the tire 50, as shown in Figures 7 and 11. The tire 50 has a tread portion 51 and a sidewall 52 connected to the tire 50, and a convex ring 53 projecting toward the tread portion 51 is provided on the inside of the base of the sidewall 52. When mounting the explosive tire extension device 100 to the tire 50, the hooking portion 14 of the support element 10 is engaged with the main wall 12 to hook onto the sidewall 52. The support element 10 is then restrained in an annular shape using the bundle ring 20, the steel cable ring 30, and the elastic ring 40, and the support elements 10 are brought close to each other. As a result, even when the tire 50 punctures and loses internal pressure, causing the tread portion 51 to collapse inward and the tread portion 51 to apply pressure to the explosive tire extension device 100, the support elements 10 of the explosive tire extension device 100 can maintain their annular arrangement shape. The tread portion 51 of the tire 50 can be supported by each support surface F of the support element 10. As a result, the tire 50 supported by the tire extension device 100 can remain in a state where it can roll even after being damaged and leaking air, preventing the vehicle from becoming uncontrollable, and allowing the vehicle to be driven to the shoulder of the road for a temporary stop, or to a repair shop for repairs or tire replacement.

[0021] The above description is merely a preferred embodiment of the present invention. Equivalent modifications made based on the specification and claims of the present invention should, of course, be included within the scope of the present invention. [Explanation of symbols]
