The specific embodiment
Fig. 1 and Fig. 2 are the perspective view and the profiles of major part of the soft tennis of the expression first embodiment of the present invention, and Fig. 3 represents the major part profile of the inflator pump of the second embodiment of the present invention.
First embodiment
In Fig. 1 and Fig. 2, in the soft tennis 1 according to present embodiment, rubber valve 3 is engaged by cement in the mode of end outward and is fixed on the aperture 2a of the part that is formed at spherical shell 2.In addition, in order to should be readily appreciated that, in Fig. 1 and Fig. 2, draw rubber valve 3 very big, rubber valve shown in the size 3 is very little in fact as will be described.
In addition, valve body 3c forms the taper that diminishes gradually from outer end side direction inner end side external diameter.
Because the profile of teat 3a forms more to the more little taper of outside external diameter, even deviation is arranged so be formed at the internal diameter size of the aperture 2a of spherical shell 2, also can be absorbed by the tapering, but also can make the outer peripheral face seamless combination of inner edge and the teat 3a of this aperture 2a, the situation that the inner edge of this aperture 2a curls can not take place.Especially, if on the conical surface that cooperates with teat 3a external diameter, form the inner edge of aperture 2a, can prevent further that the inner edge of aperture 2a from upsweeping.
In this rubber valve 3, be formed with the entrance hole 3d that bottom opening portion is arranged that is used for the insertion rod of inflator pump is imported teat 3a center, with the inner face 3f ground formation slit 3e of not shown bit alignment this entrance hole 3d and perforation valve body 3c.In addition, slit 3e is formed at the inside of ball 3, and not and periphery.
The higher limit of the gross weight of the rubber valve 3 in the present embodiment is made as 0.8g, and as for material, the compounding chemicals that adds sulphur uses the softening agent of following sticker of 2 heavyweights and 1-5 heavyweight, also has pigment is below 2 heavyweights, does not use powder to fill.In addition, polymer is that NR, IR, BR use separately or its mixture.
In addition, the rubber hardness of valve 3 is below 35 ° 30 ± 5 °.Also have, the mensuration of rubber hardness is used the デ ュ ロ メ- ィ プ A (DUROMETER TYPE A) of Shimadzu Scisakusho Ltd's system.
In addition, the thickness of thin layer flange part 3b is the 0.3-0.8 millimeter, has made very big contribution to realizing lightweight.
And then the external diameter of valve body 3c is large-diameter portion diameter 5-10 millimeter, minor diameter part diameter 3-8 millimeter, and the length of rubber valve 3 is the 5-11 millimeter.
This slit 3e is 1.0 millimeters-3.0 millimeters formation with width.
With the hard basketball difference of spherical shell, the spherical shell of soft tennis is very soft, and, on rubber valve, can be added with very large impulsive force during actual the use, perhaps sometimes racket can directly impact rubber valve, and this is air tight with regard to requiring rubber valve can hold out against this impact, so, very natural, be used for the hard ball rubber valves of spherical shell such as basketball and vollyball and can not intactly be applied to this soft tennis.
Simple in order to satisfy such requirement, for example as long as rubber valve is done greatly, strengthen the elastic force that acts on slit, improve the sealing property of slit, sharply increase even just we can say the air pressure in the soft tennis, also can keep its air-tightness.But,, then can not obtain the high leakproofness of slit, damage the air-tightness of device possibly if rubber valve is really up to the mark.
And then, if the weight of rubber valve increases, probably can make soft tennis lose whole machine balancing, cause unexpected batting track.
The rubber valve 3 of present embodiment has solved the peculiar problem in this soft tennis, form the taper that diminishes gradually to the inner face external diameter from the outer end by outer shape with valve body 3c, therefore external diameter is the thickness attenuation of the inner end side of path, the rigidity of the inner end side of valve body 3c descends thus, the favorable sealing property of the slit 3e of this inner end.
In addition, because the outer end side of rubber valve 3 is thicker, so compare its rigidity height with the inner end side, even it is also little to be subjected to the ratio of big impulsive force generation extreme deformation when impacting, be difficult to make valve body 3c that moderate finite deformation takes place on the one hand, on the other hand, with very big elastic force extruding slit 3e slit 3e is blocked.
Certainly because the elasticity slit 3e of rubber can obtain sealing on the axial whole length of rubber valve 3, particularly when impacting soft tennis, rigidity by making the big outer end side of diameter is bigger than inner end side, suppress distortion as far as possible, reducing air leaks, make the rigidity inner end side littler easily flexible strain take place and make its function simultaneously, can reduce air as far as possible and leak with check-valves than outer end side.
And then, in the present embodiment,, flange part 3b is made thin wall shape because the outer shape of valve body 3c is a taper in addition, this has contribution to alleviating rubber valve weight.
Below, when the air in the soft tennis 1 reduces, the insertion of inflator pump rod to be inserted in the entrance hole 3d of rubber valve 3, slit 3e is widened on the limit, and the limit will be inserted excellent leading section and will be inserted into the position of stretching out from the inner 3f of rubber valve 3.
At this moment, because spherical shell 2 softnesses of soft tennis 1, friction between the insertion rod of rubber valve 3 and above-mentioned inflator pump is big in addition, so must pinch rubber valve 3 with finger in the mode that props up spherical shell 2, the insertion rod of inflator pump is firmly inserted the slit 3e of rubber valve 3.Thus, can think that slit 3e is easily impaired and can not obtain sufficient sealing.In addition, can think when firmly gripping rubber valve 3, can make the spherical shell 2 that props up impaired.

In addition, be formed with threaded portion 7, cover cap member 9 spiral shells that insert rod 8 and terminate in this threaded portion 7 at the root that is used to install the pump parts 6 that insert rod 8.Pump parts 6 are formed with inflation with hole portion (not shown) in rearward end, can be when injecting air by referring to that with for example thumb abdomen pins this hole portion on one side, be pressed on one side that pump parts 6 make its distortion and in the air injection soft tennis 1 that pump parts 6 are interior.
In this second embodiment, be provided with the lubricants such as sponge that scribble lubricants such as silicone oil at the inner surface of cap member 9 and be coated with body 10, and cap member 9 is being installed to when inserting on the rod 8, the lubricant that lubricant is coated with body 10 will be in and be coated in the state that inserts on the rod 8 always.
Therefore, taking off cap member 9 from inflator pump 5, and will insert rod 8 and insert rubber valves 3 time, owing to be coated in the lubrication of the lubricant that inserts excellent 8 outer surfaces, insert rod 8 and successfully insert in the slit 3e of rubber valve 3, the inner 3f that the 8a of hole portion passes rubber valve 3 enters in the spherical shell 2.
Like this, because when utilizing the inflator pump 5 of this second embodiment that air is injected the soft tennis 1 of this first embodiment, can the slit 3e that rod 8 successfully inserts rubber valve 3 will be inserted, so can insert rubber valve 3 fully will insert rod 8 with the hand-held state of holding soft tennis 1 gently.
Thus, can not use the method that firmly pinches the so easy damage spherical shell 2 of rubber valve 3 that air is injected, in addition owing to can not damage the slit 3e of rubber valve 3, so can keep the sealing that slit 3e has.
In addition, after will inserting rod 8 and extracting, be coated on the inner peripheral surface of slit 3e owing to be coated in a part of inserting the lubricant on the rod, so the sealing of slit 3e improves.
