20090241738 | TIRE PUNCTURE REPAIR DEVICE - Provided is a tire puncture repair device capable of injecting a puncture sealing agent into a tire stably and speedily. A container is compressed between plate members by placing one of the plate members on the ground and pressing down the other one of the plate members with a foot. Thereby, the puncture sealing agent is discharged from the container and is injected into the tire through an injection tube. Discharge amount control means is attached to the injection tube to level an amount of the puncture sealing agent to be discharged. | 10-01-2009 |
20090277555 | RUN-FLAT SUPPORT BODY AND METHOD OF ASSEMBLING THE SAME - A run-flat support body and a method assembling the same that improves reliability during running by eliminating mechanical joint components and realizes weight reduction and uniform mass-production are provided. The run-flat support body of the present invention comprises a pair of elastic rings fitted to a rim of a wheel and an annular shell bridging between these elastic rings. In the run-flat support body, the elastic rings and the annular shells are integrally joined, at least one discontinuous spot is provided in a circumference of the annular shell and the elastic rings, a connection structure is formed in which butted ends of the annular shell are joined together by welding, and joining between the annular shell and the elastic ring is partially released in the vicinity of a butted position of the annular shell. When the run-flat support body is inserted into a cavity portion of a pneumatic tire and the butted ends of the annular shell are joined together by welding, the welding work on a portion covered by the elastic ring is performed in a state where the elastic ring is retreated from the butted position of the annular shell. | 11-12-2009 |
20100000647 | RUN-FLAT SUPPORT FOR PNEUMATIC TIRE - Provided is a run-flat support for pneumatic tire, which support is improved in durability while still achieving a lightweight. A run-flat support | 01-07-2010 |
20110067794 | PNEUMATIC TIRE - A pneumatic tire is described having a designated rotational direction, wherein drainage grooves in a tread portion are positioned on each side of a tire equatorial line extending at an angle in a direction opposite the rotational direction while curving towards an outside in the tire width direction. An inclination angle θ | 03-24-2011 |

20090038730 | Run Flat Supporter for Pneumatic Tire - Provided is a run flat supporter for pneumatic tire which can be used for a plurality of kinds of pneumatic tires having different tire sizes. The run flat supporter includes an annular shell and elastic rings. The annular shell has an outer peripheral side formed as a tire support surface and an inner peripheral side bifurcated into left and right leg portions. The elastic rings are attached to each of the tips of the left and right leg portions. The run flat supporter is supported on the left and right seats of a rim of a wheel with the elastic rings interposed therebetween. The run flat supporter for pneumatic tire is characterized in that at least one of the left and right leg portions of the annular shell is divided into an outer-diameter-side shell and an inner-diameter-side shell, and the inner-diameter-side shell is connected to the outer-diameter-side shell so as to be displaceable in the tire axial direction. | 02-12-2009 |
20100218883 | PROCESS FOR PRODUCING SELF-SEALING PNEUMATIC TIRE AND APPARATUS THEREFOR - A process in which a self-sealing pneumatic tire consisting of a pneumatic tire after vulcanization molding furnished with a sealant layer being uniform without thickness irregularity and a cover sheet layer therefore is produced without the use of an organic solvent and expensive apparatus; and an apparatus therefore. The process is characterized by sequentially performing the operations of injecting a viscous sealant material onto the internal surface of a pneumatic tire (T) after vulcanization molding; diffusing the sealant material into a sheet form by centrifugal force while rotating the pneumatic tire (T) around the tire axis to thereby form a sealant layer ( | 09-02-2010 |
20120210933 | APPARATUS FOR PRODUCING SELF-SEALING PNEUMATIC TIRE - An apparatus for producing a self-sealing pneumatic tire includes a rotational drive apparatus that grasps a vulcanization molded pneumatic tire and rotationally drives the pneumatic tire around a tire axis, together with a spray nozzle for a sealant material, a spray nozzle for a cover material, and an irradiating device that irradiates an electron beam, infrared rays, ultraviolet rays, or ultrasonic waves that are provided on a lateral part of the pneumatic tire grasped by the rotational drive apparatus in a manner such that each of the spray nozzles and the irradiating device can move in and out of a cavity of the pneumatic tire. | 08-23-2012 |

20080295938 | Tire/Wheel Assembly - Disclosed is a tire/wheel assembly allowed to still further enhance run-flat durability thereof with a simple configuration. A tire/wheel assembly of the present invention is a tire/wheel assembly where a run-flat support member inserted, coaxially with a rim, in a cavity portion of a pneumatic tire. The tire/wheel assembly is formed of a configuration where a retention groove for lubricant on an inner peripheral surface of the pneumatic tire is provided in a manner that the retention groove is faced at least to an apex of the run-flat support member. | 12-04-2008 |
20090107603 | Run-Flat Support Member, Pneumatic Tire With Run-Flat Support Member, and Method of Producing Thereof - A run-flat support member having an annular shell for supporting a tread portion when a pneumatic tire is operated in a run-flat condition. The annular shell is formed from a shell body which is annularly curved and has opposite circumferential edges that are butted against each other and are joined. The shell body is structured such that the butted opposite circumferential edges come into contact with each other by forces acting in directions where they are butted against each other. | 04-30-2009 |
20090114326 | METHOD AND DEVICE FOR FIXING RUN-FLAT SUPPORT BODY TO PNEUMATIC TIRE - Provided are a method and a device for fixing a run-flat support body to a pneumatic tire. The method and the device can achieve the prevention of unevenness in the distribution of the lubricant applied to the inner surface of the tire in which the run-flat support body is used, and thus of deterioration in the weight balance of the wheel. In the fixing method, the run-flat support body configured of a pair of elastic rings to be arranged around a rim and an annular shell installed across these elastic rings is fixed to the pneumatic tire which is to be fitted to the rim with the run-flat support body inserted into a hollow part of the tire. The fixing device, for restricting the radial movements of the run-flat support body inserted into the hollow part, is fitted to at least one of bead parts of the pneumatic tire before the pneumatic tire is fitted to the rim so as to coaxially hold the pneumatic tire and the run-flat support body. | 05-07-2009 |
