Description

FIELD OF THE INVENTION

The present invention relates to a tire pressure collector and more particularly, to an enclosure for enclosing functional components of said tire pressure collector.

BACKGROUND OF THE INVENTION

A prior art tire pressure detector is coupled with a car tire gas nozzle through its pneumatic pipelines . Tire pressure date of the tire is obtained by at first opening a valve of the gas nozzle, then accessing interior of the tire, and finally measuring pressure through its gas pressure detecting device. The gas pressure data is acquired via mechanical or electronic manner thus achieving detection purpose. A car tire pressure collector also employs this principle and is somewhat different from a tire pressure detector in that the collector mainly collects gas pressure of one or more tires, while the detector mainly detects gas pressure of a single tire. Based on above difference, during operation, design requirement of the detector is often simple and focuses on realization of its function. Comparatively, more precise design is needed for the collector so as to get better grip effects and is suited for long term running.

In terms of marketability, tire pressure detector generally can be found in car repair shops for occasionally determining whether leakage occurs to a specific tire. With gradual development of external tire pressure gauges, more and more gas stations, car beauty shops and repair shops will sell external tire pressure gauges. Pre-sale tire pressure detection and collection as assistant marketing means will bring potential marketplace demand, this helping product promotion by salesman. The salesman may provide the driver with tire pressure detection service free of charge for selling their external tire pressure gauges. Often, there are a number of clients in this situation. Salesman has to detect tires of each car, this involving huge number of tires and being time-consuming. Accordingly, there is a need to provide a tire pressure collector having an improved enclosure suitable for long period use, and this product will have greater utility than a convention tire pressure detector.

A conventional tire pressure detector is not suitable for long term operation because its enclosure design is not convenient for gripping. Moreover, considering convenient gripping, its mechanics when collecting gas pressure should also be considered. Otherwise, it will still not be able to operate for long time. Of course, this kind of prior art gauge can't meet this design requirement due to failure to considering above potential marketplace requirement.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is described in further detail in conjunction with various embodiments and accompanied drawings.

Refer to FIG. 1 showing a front view of a tire pressure collector according to the invention to indicate construction of an enclosure. Internal construction of the tire pressure collector is not shown in figures. For example, functional members of the collector built in the enclosure such as a valve for pushing a gas nozzle, mechanical valve member for communicating inside space of the tire so as to obtain tire pressure, gas communicating member and detection circuit for conducting tire gas into the gas detection circuit, and an indicator circuit for finally showing data obtained by the detection circuit, are not shown, as these members are well known by person of skill in the art.

The enclosure includes two parts, one of which is a gas communicating portion 1 and the other one is a main body 2.

The gas communicating portion 1 is generally of a cylindrical shape and internally has a cylindrical space 10. One end of the cylindrical space extends out of the gas communicating portion 1 so as to define an opening 10 at one end of the gas communicating portion 1. A mechanical valve member used for the tire pressure collector may be mounted in the opening 10. The mechanical valve member may be pressed against the gas nozzle of the tire so that a valve of the gas nozzle will be opened. Therefore, interior gas pressure of the tire is communicated with the cylindrical space. Next, gas pressure is conduced to the detection circuit by said gas communicating member. Pressure detection is performed using a pressure sensor of said detection circuit.

Referring to FIG. 1, said main body 2 generally is of an ellipse shape and as a result, its left and right sides are of convex arced shape. Inside the main body 2 is a receiving space (not shown) for receiving the gas communicating member, detection circuit and indicator circuit of the tire pressure collector. Considering placement of functional parts of the collector, it is preferred that the receiving space of the main body 2 be communicated with the cylindrical space of the gas communicating portion 1. In implementation, the gas communicating portion 1 and main body 2 each may be divided into two identical sub-portions, and corresponding sub-portions of the portion 1 and body 2 at a same side may be integral. During assembly, these sub-portions may be fastened together so as to form said enclosure.

To facilitate further description of the invention, as shown in FIG. 1, an axis of the cylindrical space of the gas communicating portion 1 is defined as a reference axis 1x. One side where the opening 10 is formed is defined as left side, while the other side opposite to the side where the opening 10 is formed is defined as right side. Correspondingly, location below the axis may also be clearly defined.

The main body 2 is located below the reference axis 1x and is connected with the gas communicating portion 1 (they can be formed integrally). The main body 2 is entirely of an arc shape and its left and right side views are depicted in FIGS. 2, 3. In these figures, the horizontal direction is the thickness direction and the thickness is small.

Along the horizontal direction of FIG. 2, four gripping portions 22 are formed on the main body 2 from top to bottom. Each gripping portion 22 is concave from left to right side of FIG. 1 and is generally a concave curved surface. In addition, uneven texture is formed on each gripping portion 22 for increasing friction when being gripped. Four gripping portions 22 are close to and separate from each other so as to conform to four fingers except for thumb of a person. It can be seen from FIG. 2 that four gripping portions may be slightly tilted for example towards left-bottom or right-bottom so as to conform to left hand or right hand habit respectively.

Along the horizontal direction of FIG. 3, at one side opposite to the opening 10 of the gas communicating portion 1, a regularly inwardly curved depression portion 12 is provided on the gas communicating portion 1. Similarly, uneven texture is formed on the surface of the depression portion 12 for enhancing friction when depressed by the thumb. It is clear from FIG. 3 that the depression portion 12 is of generally an ellipse shape. Therefore, from top to bottom of the depression portion 12, there is a transverse arc segment with an angle of 70-90 degree and preferably of 80 or 81 degree. Said depression portion 12 may extend cross the gas communicating portion 1 and main body 2. Along a vertical direction of FIGS. 1-3, at least part of the depression portion is higher than the gripping portions 22 and especially higher than the uppermost gripping portion (that is, the gripping portion 22 to be touched by the first finger).

In a summary, the gas communicating portion 1 and main body 2 together construct the tire pressure collector enclosure. Said depression portion 12 and the opening 10 of the gas communicating portion 1 are located respectively at two sides of an axis. During operation, depression imposed by the thumb may be effectively applied to the valve of the gas nozzle. Moreover, four gripping portions 22 formed on the main body 2 may be useful for being gripped by the rest four fingers of a person. Accordingly, it meets ergonomics design, and is suitable for repeatedly performing tire pressure collection for a long time, thus assisting in expanding application of the tire pressure collector.

Though various embodiments of the invention have been illustrated above, a person of ordinary skill in the art will understand that, variations and improvements made upon the illustrative embodiments fall within the scope of the invention, and the scope of the invention is only limited by the accompanying claims and their equivalents.
