Embodiment
Fig. 1 and Fig. 2 are the perspective view and the sectional drawings of major component of the soft tennis of the expression first embodiment of the present invention, and Fig. 3 represents the major component sectional drawing of the gas-filled 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 joint compound 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, for easy to understand, 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.
Rubber valve 3 is when outer end central authorities have the teat 3a that cooperates with the aperture 2a of spherical shell 2, also be formed with the thin layer lip part 3b that links to each other with this teat 3a base portion, this rubber valve 3 is made of the solid rubber components from the inside distolateral column valve body 3c that forms of this lip part 3b, has integrally formed unibody construction.The outer surface side of this thin layer lip part 3b scribbles joint compound.
In addition, valve body 3c forms with the taper that diminishes gradually from outer end side direction inner end side external diameter.
Because the profile of teat 3a is to form to the more little taper of outside external diameter more, 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 circumferential 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 introduction hole 3d that bottom opening portion is arranged that is used for the insertion rod of gas-filled pump is imported teat 3a center, with the interior edge face 3f ground formation slit 3e of not shown bit alignment this introduction hole 3d and perforation valve body 3c.In addition, slit 3e is formed at the inside of ball 3, and not and periphery.
The CLV ceiling limit value 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 tenderer of following bonding material 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 °.
In addition, the thickness of thin layer lip 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 impact 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 sealability of slit, sharply increase even just we can say the air pressure in the soft tennis, also can keep its tightness.But,, then can not obtain the high leak tightness of slit, damage the 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 with the taper that diminishes gradually to the interior edge face external diameter from the outer end by outer shape 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 impact 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, reduce air leakage, make the rigidity inner end side littler easily flexible resiliently deformable take place and make its function simultaneously, can reduce air leakage as far as possible with safety check than outer end side.
And then, in the present embodiment,, lip 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 gas-filled pump rod to be inserted in the introduction hole 3d of rubber valve 3, slit 3e is widened on the limit, and the limit will be inserted excellent front end 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 gas-filled 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 gas-filled 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 screw section 7, cover cap member 9 spiral shells that insert rod 8 and end this screw portion 7 at the root that is used to install the pump parts 6 that insert rod 8.Pump parts 6 are formed with air inlet 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, push away that the limit is pressed into that pump parts 6 make its distortion and with in the injection of the air in the pump parts 6 soft tennis 1.
In this second embodiment, be provided with the oiling agents such as sponge that scribble oiling agents such as silicone oil at the internal surface of cap member 9 and be coated with body 10, and make when inserting on the rod 8 in that cap member 9 is installed, the oiling agent that oiling agent 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 gas-filled pump 5, and will insert rod 8 and insert rubber valves 3 time, owing to be coated in the lubrication of the oiling agent 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 this second embodiment's gas-filled pump 5 that air is injected this first embodiment's soft tennis 1, 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 oiling agent on the rod, so the sealing of slit 3e improves.
In this second embodiment, the outer circumferential face that inserts rod 8 has carried out electroplating processes, and the diameter that inserts rod 8 is the 0.8-1.2 millimeter, and length is the 13-20 millimeter, as long as its length as mentioned above, the interior edge face 3f that can make the 8a of hole portion pass valve 3 really when being inserted into rubber valve 3 gets final product.
