BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates mainly to an apparatus for urging air supply to a tire after a flat tire is repaired more quickly than other tires.

[0002]

2. Description of the Related Art When a tire for a vehicle is punctured, it can be replaced with a spare tire, but when such a spare tire is not provided, or two wheels are punctured simultaneously in a four-wheel vehicle. Sometimes, it will not be possible to drive on a motorcycle (motorcycle) that does not always have spare tires. In such a case, you can usually request a repair company, but it is difficult to request a repair company if a puncture accident occurs, for example, while driving or moving, especially in a remote suburb or mountain area. In consideration of the occurrence of such an emergency situation, generally, various repair tools that allow the puncture repair by themselves to be relatively easy are commercially available.

[0003]

By the way, even if the puncture can be repaired with the repair tool as described above, it is necessary to inject an appropriate amount of air into the tire when the vehicle is used again. If there is no air supply stand nearby, moving the car with no air supply will cause the bead to come off the rim and damage the tire itself. As a countermeasure against such an emergency, it is usually necessary to carry an air supply device such as an inflator (hand pump) in addition to the puncture repair tool. However, since such an air supply device is larger in size than the above-described flat tire repair tool, it is not suitable for a four-wheeled vehicle, etc.
It is generally not preferred to always have a motorcycle etc., but a hand-pushed simple air pump used in such a temporary case cannot obtain sufficient air pressure, and it is also considerably used. It requires labor.

The present invention has been made to cope with such a situation, and it is possible to transfer a minimum required amount of air from other usable tires to a tire after puncture repair. (EN) Provided is an air supply device which is small in size and easy to operate, inexpensive, and easy to use in an emergency. In addition, the device of the present invention can be used for supplying air to a ball, a floating bag, a rubber boat, etc., which requires air at the time of use.

[0006]

In the device of the present invention, an air supply member such as a tire after repairing a puncture has a nozzle mouthpiece fitted to one end of the hose fitted to the mouthpiece of the valve cylinder. When the seat plate is advanced, the projecting rod provided on the seat plate presses the valve rod in the valve cylinder opening portion, and the valve cylinder opening portion is opened, and at the same time, the cylinder packing in the mouthpiece is pressed in the axial direction. By deforming, the outer circumference of the mouth of the valve cylinder is held, and the nozzle is connected and held to the valve cylinder. Next, when the mouthpiece of the nozzle provided at the other end of the hose is fitted and pressed against the valve cylinder of a normal tire, the needle bar inside the mouthpiece pushes the valve bar inside the valve cylinder and immediately presses the high pressure inside the tire. The air is guided into the hose to open the check valve provided between the passages, and the air is sent through the nozzle into the air supply body until the required pressure is reached.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3, reference numeral 1 denotes a pressure-resistant flexible hose having a length of about 2 m, which allows air having a required pressure to pass therethrough.
Nozzles 2 for extracting compressed air are connected to the other end, and nozzles 3 for supplying compressed air, which are connected to the deflated tire wheel B as a supply target of air, are connected to the other end. The take-out nozzle 2 is pushed into the center of a mouthpiece 2a which is made to be able to communicate in an airtight manner by being pushed into the outer circumference of the mouth of the valve cylinder A ₁ of the tire wheel A so as to communicate with the valve cylinder at the time of the pushing. a head 2b for pressing open the valve stem a ₂ in a _1, tighten with a tubular packing 2e on the inner periphery of Hari杆2d and the mouth gold formed by the vent hole 2c is communicated inside and outside with the base portion of the head portion It is configured. However, the other delivery nozzle 3 is a mouthpiece 3 which can be connected and held airtightly when fitted into the mouth of the valve cylinder B ₁ of the tire wheel B.
A non-return valve 3 in which the hose is elastically pressed into the tubular part 3b of the girth to which the hose is connected.
Tighten provided c, pierced further and突杆3d which are capable of pressing the valve stem B ₂ of the valve cylinder B ₁ in the center outer surface in the mouth in gold, around the projecting rod to Tsuguchi 3e to the inner and outer surfaces And set screw 3f
Seat plate 3g that can be moved back and forth in the axial direction by rotating
And the mouth plate edge 3h by advancing the seat plate.
A cylindrical packing 3i that can be compressed in the axial direction is installed between and. The push screw 3f moves the seat plate 3g in the axial direction by rotating the push screw 3f.
Another lever fan, for example, a rod rod protruding from the seat plate and exposed to the outside of the upper portion of the mouthpiece 3a is pivotally attached to the upper end of the rod rod so as to be rotatable, and a cam is partially provided on the fan rod. The seat plate may be moved forward and backward by moving it up and down by a turning operation, and the hose 1 may be provided with a pressure gauge or a pressure reducing valve at an intermediate portion (not shown).

In the case of the above structure, first, FIG. 2 and FIG.
As shown in (A), the mouthpiece 3a of one of the feeding nozzles 3 requires air, for example, a tire wheel B after puncture repair.
When the set screw 3f is fitted in the mouth of the valve cylinder B ₁ and the push screw 3f is rotated in the forward direction, the seat plate 3g presses the cylinder packing 3i in the axial direction, thereby holding the outer circumference of the mouth of the valve cylinder B _1. As a result, the mouthpiece 3a is connected to the valve cylinder in an airtight manner. Then, as shown in FIGS. 2 and 3 (B), when the valve cylinder A ₁ of the tire wheel A is fitted in the mouthpiece 2a of the pressurized air extraction nozzle 2, the mouthpiece is pushed in the axial direction to push the needle bar. 2d
The valve rod A ₂ in the valve cylinder A ₁ is pushed in by the head portion 2b of the valve so that the compressed air in the wheel A is ventilated in the vent hole 2c and the hose 1.
After that, the check valve 3c in the mouthpiece 3a is opened, and the check valve 3c is delivered into the mouthpiece. This air immediately enters the tire wheel B from the valve cylinder B ₁ through the passage 3e provided in the seat plate 3g. The transfer of the pressurized air may be carried out by stopping the replenishment to such an extent that the air pressure of the tire wheel B is raised and the vehicle can be operated reasonably. The transfer will stop naturally, so that the nozzles 2 and 3 can be removed in this order when the desired work is completed.
It should be noted that the tire wheel A is shown in the case of the own vehicle of a two-wheeled vehicle, but it may be of another vehicle.

In the above, the body to be replenished with the pressurized air is deflated.
I have described an example of a tire wheel that has been
The air-supplemented body may be another floating bag that requires air supply.
It may be a rubber boat or the like. By the way

Advantages of the Invention According to the present invention, the supply of pressure air to various tires such as tire wheels after puncture repair that requires air supply and other rubber boats, etc., to supply air to the required air pressure It can be peeled off easily and quickly from other tire wheels that maintain For this reason, it is not necessary to use the spare tires, for example, when a motorcycle suffers a puncture accident while driving, in areas where there is no air supply facility such as gas stations, or in other places where there is no air pump. Since a large amount of pressurized air can be supplied from other tire wheels on an emergency basis, it is possible to avoid an emergency situation such as inability to run, and moreover, it is possible to prevent air from being taken out from the normal tire wheel more than necessary. Therefore, it can be used with confidence.
