Description

The present invention relates to a container capable of checking compressed air leakage of a tubeless tire without removing a wheel from a vehicle body, from a moped scooter to a large motorcycle.

At present, when tubeless tires are punctured, air leaks can be checked by adding bubbles to the sponge and then foaming the tires or spraying soapy water directly on the tires to detect air bubbles that are amplified. The mainstream method is to check for leaks.

This method is an effective inspection method when a certain amount of compressed air leaks from the tire, foil, and air injection valve, but it is very difficult to find a very small amount of compressed air leak.

The final confirmation method is to remove the foil from the vehicle body and place the tire and foil in a container filled with water to check for leaks of compressed air. Is very uneconomical.

In particular, the driver will drive a vehicle with a low-pressure tire without his knowledge, increasing the risk of falling or causing an accident. Many applications using electronic circuits have been filed as methods for detecting air leaks, but all require expensive equipment.

When checking the compressed air leak by removing the foil from the vehicle body and putting it in the water stretched on the container, even if the compressed air leak cannot be confirmed, a work fee will be generated and the inspection is often rejected. It is very detrimental to both repairers and drivers. In particular, the driver will drive a vehicle with a low-pressure tire without his knowledge, increasing the risk of falling or causing an accident. However, the use of this container makes it possible to easily and reliably check for compressed air leaks with a small amount of water without removing the foil, which is very meaningful for both repairers and operators.

Japanese Patent Laid-Open No. 08-086709

The final confirmation method is to remove the foil from the vehicle body and place the tire and foil in a container filled with water to check for leaks of compressed air. It is very uneconomical because it uses water.

Even if the inspection cannot be confirmed due to the inspection for these reasons, the inspection fee is often rejected because a work fee is generated. It is very detrimental to both repairers and drivers. In particular, the driver will drive a vehicle with a low-pressure tire without his knowledge, increasing the risk of falling or causing an accident. However, the use of this container makes it possible to easily and reliably check for compressed air leaks with a small amount of water without removing the foil, which is very meaningful for both repairers and operators.

As a recent trend, customers (users) tend not to pay for small checks. Punk repairs are also included. The fact is that there are a lot of people who want to ride a little more to see if they pay for the inspection. In the case of a complete inspection, the only problem was that there was only a method of spotting by removing the foil from the car body and placing it in a container filled with water. . However, these problems are solved with the container of the present invention.

Since only a small amount of water is used for inspection and no detergent is used, it is environmentally friendly. Since air leaks can be inspected at a low charge, repairers and customers can confirm air leaks together, and both can be confirmed with visual confirmation that there are no air leaks after repairs are completed. There is a completely different reaction between having a customer check with a detergent and using a container to check in water. It's hard to understand because it cracks even if bubbles are added, but if you use a container to make sure that no air leaking bubbles appear in the water, you can be completely convinced.

1 Improved container stability during work by flattening the bottom. This is especially effective when the tires are large-diameter tires because the amount of water used is large.
2 Changed the bend of the back and forth.
3 The height of the small arc is higher than the height of the large arc and has a side that connects the apexes of the arc. 4 Lifting and supporting rods are attached to the left and right of the container. When inspecting small-diameter tires, enter from the side of the tight bend (first bend side), lift the rear of the container, lower the lever, and tilt the container. Therefore, the amount of water to be used can be reduced, and contact between the muffler, the engine and the like and the container can be prevented.

By using the device of the present invention, it is possible to reliably repair and check the compressed air leakage of the wheels, so that both the driver and the repairer can feel secure. Further, when checking for air leaks in tubes and tubeless tires using this container, a very small amount of water is required and it is economical.

The container of the present invention can check for compressed air leaks in tubeless tires from moped scooters to large motorcycles.
The tire air leakage detection container of the present invention is a container for detecting air leakage of a tire in a state of being attached to a motorcycle, and includes a first side portion surrounding a lower portion on one side of the motorcycle, A second side portion surrounding the lower side of the other side, and a connection portion surrounding the lower peripheral edge of the tire and connecting the first side portion and the second side portion, and the first side Air leak detection of a tire by filling a liquid therein and immersing at least a part of the tire in the liquid it can.

Further, in the tire air leak detection container, the first side portion and the second side portion are a first curved portion and a second curved portion, which are bent corresponding to the tire, and the first side portion. And a straight line portion connecting the second curved portion and the second curved portion.
Further, in the tire air leak detection container, the first curved portion and the second curved portion are configured by arcs having different curvature radii.
In the tire air leak detection container, the first curved portion has a radius of curvature corresponding to a tire of a motorcycle, and the second curved portion is a curvature corresponding to a 17-inch or 18-inch tire. Has a radius.

  When a transparent material is used for the container described above, it is easy to observe fine air leakage bubbles, and the detection effect is further improved.

FIG. 1 shows a container of the present invention. 2 is an opening.
FIG. 2 is a side view of the container of the present invention. Length 580mm, height is large radius side 5 (second curved portion side) (B) (R330) is 130mm, small radius side 4 (first curved portion side) (A) (R330 It consists of a portion and a portion of R210, and the length of both is substantially equal) is 170 mm.

FIG. 3 is a view of the container of the present invention as seen from the curved surface side. (A) is a figure from the side with the smaller radius of curvature (first curved part side), and (B) is a figure as seen from the side with the larger radius of curvature (second curved part side). The difference in height is 40 mm.

The total length of the container according to the embodiment of the present invention is a length that can be entered from a small-diameter tire (10-inch tire outer diameter is approximately 420 mm) to a large-diameter tire (18-inch tire outer diameter is approximately 680 mm), and the width is the thickest tire (210 mm wide from the manufacturer as standard equipment). It is the largest that is shipped in, but it seems that there is a thicker option as well. Of course, those corresponding to a wide tire are also included in the scope of the present invention.

FIG. 4 shows the case of checking the compressed air leakage of the rear wheel of a motorcycle with a main stand. Since there is a gap between the rear wheel and the ground 7, the container 1 is slid down as it is, and water is filled to check for leaks of compressed air. Therefore, the effect of shortening the working time is great.

When checking the compressed air leakage of the front wheel of a motorcycle with a main stand, lift the front wheel until the container is inserted with a jack etc., then slide the container into the gap between the ground and the tire from the side of the loose bend, and Place the flat surface in contact with the ground to stabilize the container, and, when viewed from the side, align the front and rear gaps of the wheel and the container, and gently lower the front wheel on the two rollers in the container. Fill the container with water. Then slowly rotate the foil and check for compressed air leaks. In this case, it is desirable to fix the handle so that the foil does not move left and right during operation.

In the case of a vehicle with only a side stand, it is desirable to work in a state where the wheel is slightly lifted so that the wheel and the container do not come into contact with each other because the container may be damaged or deformed.

FIG. 5, FIG. 6 and FIG. 6 show the inspection of the small-diameter tire.
FIG. 5 shows a case where a container is inserted under the rear wheel of the moped scooter. The tire is located below the water surface 6.
FIG. 6 is a view seen from the muffler 12 side. FIG. 7 is a view from the engine 11 side. Use a motorized scooter when a container with the same radius of curvature is manufactured from the bottom 3 (flat surface) of the container to the front and back of the container by matching the length and height of the container with the large-diameter tire. In doing so, there was a problem of contact with the engine 11, the muffler 12, and the like. Further, since the size of the container has increased, there has been a disadvantage that the amount of water used becomes large even if the flat bottom surface is brought into contact with the ground and can be used with a moped scooter. In order to solve these two points, a container having arcs with different radii of curvature was used.
After the container is slid into the gap between the ground and the tire from the side of the arc having a small curvature radius (first curved portion), the container front and the tire are brought as close as possible, and the container is tilted by the support member. Use with water inside. In the present embodiment, the support member is shown, but the means for making the positional relationship between the container and the tire illustrated is not limited to this, for example, the member is inserted into the lower part of the container. But of course. After completion of the inspection, open the drain valve, drain the water in the container, and then pull out the container. By draining water first, the possibility of the container being damaged can be greatly reduced.

The present invention is very effective in improving the efficiency of repairing tubeless tires in motorcycles, bicycles and other two-wheeled vehicles, and in saving costs. Furthermore, by changing the size, it can also be used for investigation of tubeless tires for four or more vehicles such as automobiles.
