Description:

FIELD OF THE INVENTION

[0001] The present invention is related to a tire pressure balance apparatus, and more particularly to the apparatus for balancing a left tire and a right tire of a car.

BACKGROUND OF THE INVENTION

[0002] All drivers know that the impact of tire pressure on the car performance is very serious. A car will spend a lot of gas in case of less tire pressure. On the contrary, it will decrease the roadholding and easily make blowout in case of more tire pressure. Therefore, one will check the tire pressure during the car maintenance. Generally, the tire pressure index is between 26 and 35. As long as the tire pressure is located in this range, the tire should be normal. A tire pressure meter will be used to check the tire pressure of four tires of a car. If the tire pressure is less, one can pump the tire. If the tire pressure is more, one can deflate it. The tire pressure of the front tires is different from that of the back tires. But, the tire pressure of the left tires and the right tires must be the same. If the tire pressure of the left tires and the right tires is not the same, the steering wheel may be not regular and the car performance will be down. For example, the speedup, the turning and the car stopping will become worse.

[0003] The conventional tire pressure meter is always finger-wise. When the tire pressure is measured, one can get an approximate value. But, there must have an error between the measured value and the practical value. For example, the measured value may be 30, but the practical value may be 29.5 or 30.1. The error is always ignored at the measurement procedure, but it will impact on the driving safety very much.

SUMMARY OF THE INVENTION

[0004] An object of the present invention is to provide a tire pressure balance apparatus for balancing the left tire with the right tire of a car.

[0005] Another object of the present invention is to provide a tire pressure balance apparatus for promoting the driving safety.

[0006] According to the present invention, a tire pressure balance apparatus for balancing a left tire with a right tire of a car, the tire pressure balance apparatus comprising: a first air pumping head for connecting to the left tire; a second air pumping head for connecting to the right tire and stopping an air of the left tire before connecting to the right tire; and a pipe having two sides, the one side connecting to the first air pumping head and the another side connecting to the second air pumping head, a pressure of the left tire and the right tire being balanced after the first air pumping head being connected to the left tire and the second air pumping head being connected to the right tire.

[0007] In accordance with one aspect of the present invention, the first air pumping head is pinch-wise.

[0008] In accordance with one aspect of the present invention, the second air pumping head is press-wise.

[0009] In accordance with one aspect of the present invention, the pipe is a plastic pipe.

[0010] In accordance with one aspect of the present invention, the pipe has a air pumping hole.

[0011] The present invention may best be understood through the following description with reference to the accompanying drawings, in which:

BRIEF DESCRIPTION OF THE DRAWINGS

[0012] FIG. 1 is an illustration of a tire pressure apparatus according to the present invention;

[0013] FIG. 2 is an application illustration of the tire pressure apparatus according to the present invention; and

[0014] FIG. 3 is an another illustration of the tire pressure apparatus.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0015] Please refer to FIG. 1 showing the illustration of the tire pressure apparatus. The tire pressure balance apparatus 10 consists of the pinch-wise air pumping head 14, the plastic pipe 12 and the press-wise air pumping head 13. And, the pinch-wise air pumping head 14 includes a spanner 11. During operation, one can use the spanner 11 to fix the pinch-wise air pumping head 14 on the pumping hole of the left tire. Next, put the press-wise air pumping head 13 on the pumping hole of the right tire, and press it. Thus, the air in the left tire will pass to the right tire through the tire pressure balance apparatus 10. Therefore, the target of balancing the left tire with the right tire will be attained.

[0016] FIG. 2 shows the application illustration according to the present invention. After the left tire 21 and the right tire 22 of the car is pumped, one can use the tire pressure balance apparatus 10 to balance the tire pressure. The pinch-wise air pumping head 13 may be pinched on the pumping hole of the left tire 21, when the press-wise air pumping head 13 will hinder air from the left tire, then the press-wise air pumping head 13 may be press onto the air pumping hole of the right tire 22. Thus, the air of two tires will be passed each other, so the tire pressure of two tires will be balanced naturally.

[0017] FIG. 3 shows another tire pressure balance apparatus 30. There is a air pumping hole 31 adding to the plastic pipe. One can use this air pumping hole 31 to pump air to the left tire and the right tire simultaneously. Thus, the tire pressure of the left tire and the right tire will be the same after pumping. In this case, the two air pumping head should use the pinch-wise air pumping head. Certainly, the air pumping hole 31 may also use a quick coupler. Thus the user can connect to another quick coupler on an air compressor for quickly pumping air. Certainly, the tire pressure balance apparatus may add a pressure meter on the pipe to measure the tire pressure of two tires simultaneously. Secondly, the tire pressure balance apparatus may directly install on the air pump for simultaneously pumping two tires. Even the plastic pipe can modified as four plastic pipes that pass each other. Thus, the tire pressure balance apparatus can used to balance four tires for some large size cars. The pipe; may be a soft pipe, but it may be a hard pipe if need. The air pumping head may both be pinch-wise, or both be press-wise. The advantages according to the present invention are as follows:

[0018] 1. The production cost is low, because the elements of the tire pressure balance apparatus are few.

[0019] 2. The operation of the tire pressure balance apparatus is very simple.

[0020] 3. The driving safety and the car performance will be promoted.

[0021] 4. The car's life time will longer. While

[0022] While the invention has been described in terms of what are presently considered to be the most practical and preferred embodiments, it is to be understood that the invention need not be limited to the disclosed embodiment. On the contrary, it is intended to cover various modifications and similar arrangements included within the spirit and scope of the appended claims which are to be accorded with the broadest interpretation so as to encompass all such modifications and similar structures.
