Double inflation valve sphere structure

This creation is about a spherical structure of a double inflation valve, mainly for soft tennis balls and other similar inflatable spheres, by which the inflation valve attached to two different relative positions of the sphere enables the air to be quickly found when inflated. The position of the valve, while improving the balance of the ball.

According to the general soft tennis ball and other inflatable spheres, the production is mainly to make two pieces of spherical skin and to form a composite type, and to form an inflation valve at a predetermined position of one of the balls, so that the ball is inserted by the inflation valve. Inject air into the inside of the sphere with a pump or pump to inflate it to maintain the spherical shape of the sphere.

In the structure of the inflation valve, there are two different structural types of the inflation aperture hole and the non-aeration aperture hole, wherein the inflation valve having the inflation aperture hole is mainly provided with a ball insertion needle for the valve body thereof. The hole hole, and when the ball needle is not inserted, the inner end of the air-filled hole hole is closed, so that the internal gas has no leakage, because the preset inflatable hole, in addition to the oblique needle ball The needle is inserted into the inflation, and can also be applied to the insertion and inflation of the round ball needle; and the inflation-free inflation valve has no pores, so it can only be used for the insertion of the oblique needle.

Regardless of whether it is a pneumatic valve with a gas-filled hole or a gas-filled hole, each ball is only provided with a single inflation valve, which may require the user to inflate the ball. Constantly flipping the ball in order to find the inflation valve smoothly, invisible time consumption, and due to the structure of the single inflation valve, the weight of the inflation valve is biased to one side of the sphere, more or less affecting the overall balance of the sphere, It is necessary to try to solve the improvement.

In view of the fact that the inflatable ball body such as the soft tennis ball adopts a single inflation valve structure, it is easy to affect the overall balance feeling and the convenience of inflation, and the creator has specially developed and developed the spherical structure of the double inflation valve of the present invention.

In order to improve the convenience of the ball inflation, the creation of the structure is to abandon the single inflation valve structure of the conventional sphere, and to make it a dual inflation valve plan, and to make the double inflation valve at two different positions in which the spheres are in a relative state. Therefore, when the air is to be inflated, the inflation valve for inserting the ball needle can be easily found by simply flipping the ball in a small amount, and the double inflation valve has a symmetrical structure, which can effectively improve the balance feeling of the ball.

This design is aimed at the double inflation valve structure of the inflatable ball such as soft tennis. Without greatly increasing the cost of production and the weight of the ball, the ball can not only find the inflation valve more quickly when inflating, but also complete the inflation of the ball. By the structure of the double inflation valve, the center of gravity of the sphere is balanced, and the overall better balance is obtained.

Regarding the structural composition, technical means and effectiveness of this creation, I would like to further elaborate on the following examples: Please refer to Figures 1~3, and use soft tennis as an example to illustrate the first comparison of this creation. A preferred embodiment, as shown in the figure, the ball (10) of the soft tennis ball is usually produced by combining at least two pieces of spherical skin, which may be semicircular or 8 characters. Type (this part is not described in the subject matter of the creation and discussion, so it will not be repeated), and in order to give the creation sphere (10) the convenience and balance of the inflation work, it is the two pieces mentioned. The predetermined portion of the inner edge surface of the ball skin is combined with a separate inflation valve (11) (12), and the outer end of the inflation valve (11) (12) is clearly exposed on the surface of the ball skin for convenient use. It is recognized that the inflation valves (11) (12) are made of rubber material, and a gas-filled hole (13) (14) is formed in the center thereof, and a gas-filled hole (13) (14) is provided. The inner end is in close contact, so that the oblique needle ball needle (1) and the round ball needle (2) can be smoothly inserted, and the aforementioned inflation valve (11) (12) is When the position of the inner edge of the skin is combined with the two spheres into a sphere (10), the two inflation valves (11) (12) are in a corresponding symmetrical state, thereby constituting the double inflatable valve sphere of the present invention. First preferred embodiment; According to the structural composition of the above, the two inflation valves (11) (12) are arranged in the same sphere (10), and the two inflation valves (11) (12) are in two corresponding positions. Therefore, when the user wants to inflate the ball (10), it is only necessary to slightly flip the ball (10) (compared to the conventional single inflation valve), and any inflation valve can be quickly found ( 11) or (12), with the selected oblique needle ball needle (1) and round ball needle (2), by the inflation valve (11) or (12) with inflatable aperture (13) or (14 ), the ball (10) can be inflated, which is more convenient in use than the conventional structure, and because the weight of the inflation valve (11) (12) is not large, and is relatively symmetrical, so Obtaining a better balance of the sphere (10) for better practical value; please also refer to Figures 4-7 to illustrate the second preferred embodiment of the creation, as shown in the figure, the sphere ( 20) In addition to the aforementioned soft tennis, it can be extended to other balls that need to be inflated (such as: hard tennis (as shown in Figure 5), football (as shown in Figure 6), basketball (such as 7th) Figure), soft bar , softball, volleyball, etc.), and in the manufacture of its sphere (20), basically at least two pieces of spherical skin are combined and assembled into a composite type, and each of the predetermined positions of the inner surface of each sphere is formed separately. After combining the inflation valve (21) (22) made of rubber or the like to form the ball (20), the two inflation valves (21) (22) are located at two corresponding positions. And the inflation valve (21) (22) is a non-gap hole structure of the object and the use of the sphere (20), and only the oblique needle ball needle (1) can be inserted into the non-inflating hole. The inflation valve (21) (22) is used to perform an inflation operation, and thus constitutes a second preferred embodiment of the present invention, through which the position planning of the dual inflation valve (21) (22) is similarly made to inflate During operation, you can quickly find the position of the inflation valve (21) or (22), and smoothly complete the inflation operation with the oblique needle ball (1) inserted, while in the sphere (20) The overall balance can also achieve a good balance effect, breaking through the problems and defects that exist in the conventional single inflation valve sphere; that is, through the above description, it can be seen that the creation does not change the sphere and the composite type The operation mode and the principle of greatly increasing the production cost, the structure of the two inflation valves is simultaneously planned through the inside of the sphere, so that the position of the inflation valve can be quickly found by inverting the sphere when inflating, giving it a position The better convenience of the inflatable operation, while improving the overall balance of the ball, compared to the ball of the conventional single inflation valve, it has better practical value; in summary, the creation is for soft tennis. The double inflation valve structure developed by the inflatable ball type can not only improve the convenience of its inflation, but also achieve the better balance of the sphere, without breaking the principle of its production and greatly increasing the cost. The type restriction of the inflation valve sphere effectively solves the problems and defects that may exist and be derived. On the whole, it is an excellent and outstanding innovation. Structure, Yuan filed a patent application in accordance with law.
