PUNCTURE-PROOF STRUCTURE FOR TIRES

Abstract

A puncture-proof structure for tires provides a spare tire body that can be installed to a tire rapidly and is applicable to various tire types by using fine tuning. The tire has its two top inner edges formed with circular hooked portions for engaging with the spare tire body made of serially connected combining blocks. When the tire gets punctured and damaged by a knife or a sharp article, the spare tire body allows the tire to keep work safely. Therein, the spare tire body is a C-shaped member composed of two C-shaped holding pieces. It can be engaged with the hooked portions of the tire rapidly and arm the tire with puncture-proof ability.

DETAILED DESCRIPTION OF THE INVENTION

[0024] The present invention provides an improved puncture-proof structure for tires. Referring to FIG. 1, a tire 10 has its two top inner edges formed with hooked portions 101 and is reinforced by cords arranged therein.

[0025] Referring to FIG. 10, two C-shaped holding pieces 40 each have a C-shaped body formed with plural spaced locking holes 401 and bumps 402 raised from its inner surface.

[0026] A plurality of combining blocks 20, as shown in FIGS. 2, 3 and 4, is a hollow member with two lateral sides thereof provided with through holes 201 and with its top formed as an engaging valley 202. The combining block 20 has its two lengthwise ends diagonally formed with projecting portions 203. An engaging rib 204 is formed above each of the through holes 201 at the two sides of the combining block 20. Additionally, each of the combining blocks 20 has its bottom provided with embossment.

[0027] Two linking frames 30, as shown in FIG. 5 and FIG. 5A, each of which has two linking plates 31 and a spacer arranged therebetween and is formed into an H-like body. The linking plate 31 has its two ends each provided with a pivot hole 31a. Therein, one of the linking plates 31 has its pivot hole 31a at one end thereof additionally attached by a bush 32.

[0028] Referring to FIG. 6, a pressing shaft 50 is an axle that has its two ends formed with threaded holes 501, and has a through hole 502 running radially therethrough.

[0029] A pressing bolt 60, as shown in FIG. 7, is an axle that has its two ends formed with threaded holes 601, and has a threaded retaining hole 602 running radially therethrough.

[0030] A plurality of connecting members 61, as shown in FIG. 8, each is formed like a humpback bridge with two ends thereof each having a through hole 610. A rib 612 is formed above the through hole 610.

[0031] A plurality of first connectors 90, as shown in FIG. 9, has a slat 90a and two separated bushes 90b.

[0032] A plurality of second connector 91, has a slat 91a and two separated threaded aims 91b (also referring to FIG. 14).

[0033] When assembled, the threaded arms 91b of one second connector 91 are combined with two bushes 90b from two different first connectors 90, and then retained by two nuts 92, separately.

[0034] Also included are a screw 91c, a locking tube 94

[0035] a packing screw 70 (FIG. 13),

a locknut 71 (FIG. 13), and
a plurality of adjusting members 80, as shown in FIG. 13, having a plurality of spaced notches 801 formed at one edge thereof.

[0036] FIG. 11 is a partially exploded view of a spare tire body formed by the puncture-proof structure. As shown in FIG. 11 and FIG. 12, the two C-shaped holding pieces 40 are retained by the engaging ribs 204 at two edges of the combining blocks 20. Meanwhile, the locking holes 401 of the two C-shaped holding pieces 40 are aligned with the through holes 201 at two sides of the combining blocks 20. Then the bushes 90b of the first connector 90 (referring to FIGS. 9 and 14) and the threaded arms 91b of the second connector 91 are inserted into the locking holes 401 of the two C-shaped holding pieces 40, respectively, and enter the through holes 201 of the combining blocks 20. At this time, each bush 90b of the first connectors 90 receives one threaded arm 91b of the second connector 91, so that the combining blocks 20 are connected in series. Afterwards, the nuts 92 fix the threaded arms 91b of the second connector 91, so the components are combined into two C-shaped assemblies. Additionally, a screw 91c is inserted into the locking holes 401 of the two C-shaped assemblies and the through holes 201 of the combining blocks 20 as preliminarily positioned. Therein, the foremost and the rearmost combining blocks 20 each have a linking frame 30 attached thereto, as also shown in FIGS. 5, 5A, 11 and 12. As shown in FIG. 13, the space between the two linking plates 31 at one end of the linking frame 30 allows one later wall of one combining block 20 to be received therein, so that when the linking frame 30 and the combining block 20 are assembled, the pivot hole 31a and the bush 32 of the linking plate 31 are aligned with the through hole 201 of the combining blocks 20. The screw 91c and one threaded arm 91b of the second connector 91 are respectively inserted into the locking holes 401 of the C-shaped holding piece 40, the pivot holes 31a of the linking frame 30, the through holes 201 of the combining block 20, the bushes 32 of the linking frame 30, and the through holes 201 of the combining blocks 20, and are exposed outside the locking holes 401 of the C-shaped holding piece 40 as preliminarily positioned. The space between the two linking plates 31 at the opposite end of the linking frame 30 allows one later wall of another combining block 20 to be received therein. At this time, the pivot holes 31a of the two linking plate 31 are aligned with the through holes 201 of the combining block 20. Then a pressing shaft 50 and a pressing bolt 60 are inserted into the through holes 201 of the two combining blocks 20, respectively, as also shown in FIGS. 5 and 5A. Two screws 100 are inserted into two through holes 610 from two different connecting members 61 and screwed into the threaded holes 501, 601 of the pressing shaft 50 and the pressing bolt 60, respectively. Meanwhile, two additional screws 100 are screwed into threaded holes 501, 601 at the opposite end of the pressing shaft 50 and the pressing bolt 60. Then a bush 90b of a first connector 90 is inserted into the other through hole 610 of a connecting members 61. Thus, the two bushes 90b of the first connector 90 receive the threaded aim 91b of the second connector 91 and the screw 91c. Then nuts 92 are screwed to the threaded arm 91b and the screw 91c for fixing. The locking tube 94 is inserted into the other through hole 610 of another connecting members 61 and receives the threaded arm 91b of the second connectors 91. Then a nut 92 is screwed to the threaded arm 91b for fixing, so as to form the C-shaped spare-tire body 1000.

[0037] Therein, the two C-shaped holding pieces 40 have the bumps 402 at their inner surface inlaid between the combining blocks 20, thereby further ensuring the overall stability of the spare-tire body 1000.

[0038] As shown in FIGS. 12, 13, 14 and 15, the engaging valleys 202 of the combining blocks 20 of the spare-tire body 1000 are combined with the hooked portions 101 of the tire 10. A packing screw 70 is inserted into the through hole 502 of the pressing shaft 50 and screwed into the threaded hole 601 of the pressing bolt 60 at the combining blocks 20 at the front and rear ends of the spare-tire body 1000, so as to retain the spare-tire body 1000 along the hooked portions 101 of the tire 10. Afterward, a locknut 71 is screwed to the packing screw 70 for preventing the packing screw 70 from unscrewing. Then the four screws 100 screwed to the spare-tire body 1000 at the threaded holes 501, 601 of the pressing shaft 50 and the pressing bolt 60 are slightly unscrewed to allow the notches 801 of the adjusting members 80 to fit on the screws 100. Afterward, the screws 100 are screwed tight. Therein, the ribs 612 of the connecting members 61 press against the upper edges of the adjusting members 80 so as to firmly secure the adjusting members 80 from escape, thereby provide the tire with puncture-proof capability.

[0039] To sum up, the present invention is effective in preventing puncture and ensuring driving safety with simple configuration that requires significantly reduced manufacturing costs and time and can be assembled easily.
