Abstract

A portable tubeless tire bead seater fast discharges the air from an air cylinder into a flat tire to expand the flat tie relative to a wheel rim and seat it on the wheel rim. The air cylinder is provided with multiple inlet parts. Each inlet part is provided with an intake valve that is controllable to open and close. When a tire goes flat and cannot be seated, the multiple air supply tubes are air-tightly connected with the multiple intake valves and a plurality of inflated tires, so as to extract air from the inflated tires to be transported into the air cylinder for storage and subsequent use.

Description

Portable tubeless tire seating device

The present invention relates to a tire seating device (Tire Bead Seater), in particular, relates to carrying a tire bead on a rim using a high-capacity air cylinder and forming an airtight contact relationship between the tire and the rim Type tubeless tire seating device.

The bead of the tire is usually the innermost edge of the inner and outer sidewalls of the tire. When the tire is mounted on the rim, the bead of the tire is in direct contact with the rim, especially in a tubeless tire, for example, the tire bead Connected with the rim structure to form an airtight seal, so that it can be maintained as an internal pressure chamber between the tire and the rim. Therefore, the tire can be inflated with air, nitrogen, or any other suitable gas; the internal pressure chamber is maintained at the required pressure, which in turn exerts an outward force on the tire lip to help maintain the airtightness between the tire and the rim seal.

Due to the strength and rigidity imparted to the sidewalls of many tires today, such as in particular larger automobile and/or truck tires, the lip of the tire may not be pressed tightly against the rim after the tire is mounted on the rim On the lip seat, an airtight internal pressure chamber cannot be created. In some cases, especially for smaller tires, sufficient air can be injected through an inflation valve to create a pressure difference between the air inside the tire and the outside air, so that although air may Between the rims, the bead of the tire is still pressed against the rim to create a seal. This may be referred to as seating the tire on the rim, allowing the tire to be inflated with air and pressurized when the tire is seated on the rim. However, in some cases, especially for larger tires, due to the large gap between the tire and the rim, it is practically impossible to inject air through the inflation valve to achieve the seating of the tire on the rim.

Therefore, a conventional method for placing the tire lip involves the use of a special pneumatic seating device that injects high-pressure air into the gap between the loose tire and the rim structure. The compressed air suddenly flows into the internal pressure chamber, forcing the sidewall of the tire to expand rapidly, and snapping the tire lip into a bead seat area of the rim structure, thereby forming an airtight seal. Air can then be used to inflate the internal pressure chamber between the tire and the rim to the desired pressure.

It is well known in the art that a high volume of air is blown between the rim and the bead of the tire, thereby creating a pressure difference between the air pressure inside the tire and the outside air pressure, thereby seating the tire on the rim on. The conventional device for accomplishing the above purpose generally includes a large pressurized air cylinder provided with an exhaust pipe for exhausting air to the outside, and the exhaust pipe is provided with a conventional exhaust valve such as a ball valve or a butterfly valve. The discharge pipe is typically a solid, leak-proof metal pipe rigidly connected to the pressurized air cylinder and extending outward therefrom. The pressurized air cylinder and the exhaust pipe may be positioned to swell high volume air from the pressurized air cylinder into the tire. In order to seat the tire on the rim, the conventional device's pressurized air cylinder must be sized to maintain enough air at a sufficiently high pressure to inflate the tire relative to the rim and be completely filled The volume of the tire reaches a pressure value greater than atmospheric pressure.

As mentioned above, the conventional tire seating device must use a large air compressor, and a large amount of air is blown into the pressurized air cylinder in advance; the portable small air pump generally used with the vehicle cannot meet the conventional tire seating device. Use characteristics of air. Therefore, conventional tire seating devices and large air compressors are usually only found in professional-grade tools used in professional car repair shops or tire factories.

The general vehicle owner has no large air compressor, so it is difficult to carry the conventional tire seating device that must be pre-inflated with the large air compressor. When an air leak occurs accidentally on the wheels, the owner cannot use DIY to reseated the tire that has lost its seal due to the accident on the rim; because the tire cannot be reseated, a small portable air pump is usually driven into the tire The air inside will leak out from the gap between the tire and the rim, and the internal pressure chamber between the tire and the rim cannot be inflated to the required pressure. The owner must ask the tow truck to tow the vehicle, which may only have flat tires and no other failures, to the repair shop or tire factory for maintenance, increasing the time and expense the owner spends waiting for towing maintenance.

Generally, if the owner carries the conventional tire seating device with the vehicle for backup, because the pressurized air cylinder must normally store a sufficiently high volume of air, not only due to the increase in weight, the vehicle is more fuel-efficient to drive, and the vehicle is full of high The pressurized air cylinder of volume air also causes some risk factors and psychological burden for the driver for vehicles that often drive on uneven roads.

Furthermore, after a single use of the conventional tire seating device, the owner must return the conventional tire seating device to a professional garage or tire factory, and use a large air compressor to refill the conventional tire seating device with high-pressure air. As a result, the owner's willingness to carry the conventional tire seating device with the vehicle for standby is not high.

The purpose of the present invention is to provide a tire seating device, which is particularly suitable for being carried with a vehicle for the owner to reseated a tire that has lost hermeticity on the rim, and the tire and the interior between the rims The pressure chamber is inflated to the required pressure so that the vehicle can recover the rider.

The second object of the present invention is to provide a portable tubeless tire seating device, which does not require a large amount of air to be blown into the pressurized air cylinder in advance before use. Therefore, it does not increase fuel consumption excessively, nor does it produce a full load with the vehicle Pressurized air cylinders with high volume of air, some risk factors when driving on uneven roads and the psychological burden of drivers.

Another object of the present invention is to provide a portable tubeless tire seating device that can temporarily extract part of the gas from several normally pneumatic tires into the pressurized air cylinder only when needed. Pneumatic tires are based on the principle that the airtight seal can still be maintained; as for the tire seating device provided with sufficient gas provided by the present invention, it can be used to re-seat a tire that has lost its sealing performance on the rim.
