DEVICE FOR LUBRICATION AND/OR STORAGE OF AN INFLATION NEEDLE
Field of invention
The present invention relates to (a) inflation of inflatable articles such as inflatable footballs, soccer balls and the like which are inflated by insertion of an inflation needle through a valve of the aforementioned inflatable articles, and (b) storage of inflation needles.
Background of the invention
Regarding (a), inflatable articles such as inflatable footballs, soccer balls and the like are typically inflated via a valve which is designed to prevent the escape of gas from within the inflatable article both while the inflatable article is being inflated and after inflation. The valve therefore has to seal against an external cylindrical surface of an inflation needle which has been inserted therethrough for the purpose of inflating the inflatable article. The valves of inflatable articles are typically formed of a rubber like compound and because they are required to seal against an external cylindrical surface of an inflation needle during inflation of the inflatable article it is typically difficult to insert an inflation needle into an inflatable article.
British patent specification GB2138015A addresses the problem regarding the difficulty of insertion of an inflation needle into an inflatable article by the provision of an alternative valve. The alternative valve is designed to self lubricate a passage through which an inflation needle is inserted upon withdrawal of the inflation needle from the passage. The self-lubrication makes it easier for subsequent insertion of an inflation needle.
US patent 4043356 has addressed the problem of insertion of an inflation needle into an inflatable article by providing an alternative inflation needle. The alternative inflation needle is made from a material which includes a lubricant to assist entry of the inflation needle into an inflatable article.
In order to address the problem of insertion of an inflation needle into an inflatable article it is therefore necessary to either use an inflatable article which includes the alternative valve of GB2138015A or use the alternative inflation needle of US4043356. It is therefore desirable to address the problem of insertion of an inflation needle into an inflation article without reliance upon an inflation needle or valve which has been specifically designed to make passage of an inflation needle through an inflation valve easier.
Regarding (b), inflation needles can be vulnerable to damage or breakage either when attached to a pump or when removed from the pump and stored in a location and/or manner in which they may be damaged or broken. Furthermore, inflation needles are typically sold in a disposable package which is formed of cardboard and plastic and are sometimes sold in pairs. If the disposable package is broken for removal of one of the pair of inflation needles, the remaining inflation needle can be easily lost and/or damaged.
It is therefore desirable to provide an inflation needle storage device which is suitable for storing one or more inflation needles in a manner which at least partially addresses one or more of the above problems regarding inflation needle storage.

Best mode of carrying out the invention
Referring to Figures 1 -6, the inflation needle lubricating container 10 generally comprises a football shaped container 12 having an opening 14 and an attachment lug 16. The inflation needle lubricating container 10 also includes a cord 18 which is attached to the inflation needle lubricating container 10 via engagement of a clip 19 which is attached to the cord 18, and the lug 16. The cord 18 can, for example, be worn around a neck of a user and can also be used to enable the inflation needle lubricating container 10 to be hung up in a convenient location near a pump and associated inflation needle.
The football shaped container is hollow and, referring to Figure 8 is filled with wadding 20. The wadding 20 is designed to generally fill the internal volume of the container 12. After the container 12 has been generally filled with wadding 20, a liquid lubricant (not shown) is poured into the container 12, through the opening 14. The liquid lubricant which is poured into the container 12 is absorbed by the wadding 20. The wadding therefore ensures that the liquid lubricant is dispersed throughout the container 12.
Referring to Figures 1-8, the container is orientated so that its longitudinal axis extends upwardly. The opening 14 is positioned near an upper end of the container 12. Referring to Figure 4, the opening 14 is formed by a mouth 22 of the
container 12. A rubber grommet 24 (see Figure 5-7) is attached to the mouth 22 of the container 12.
The rubber grommet 24 is a generally donut shaped rubber grommet. It includes a groove 26 having a square shaped cross section which is formed in an outer annular surface of the rubber grommet 24. The groove 26 is designed to receive an edge 28 of the mouth 22 of the container 12.
A central cylindrical blind passage 30 of the generally donut shaped rubber grommet 24 is prevented from extending through the rubber grommet 24 by a circular rubber sheet 32 which extends from an inner cylindrical surface 34 of the rubber grommet 24. The circular rubber sheet 32 is attached to the inner cylindrical surface 34 so that it extends across one end of the cylindrical blind passage 30. The circular rubber sheet 32 is attached to less than two thirds of the circumferential length around the inner cylindrical surface 34. An unattached region 42 (see Figure 5) is therefore free to resiliently flex to provide a passage 35 through the rubber grommet 24.
The rubber grommet 24 is attached, via the groove 26 to the mouth 22 of a container 12 so that the circular rubber sheet 32 is positioned inside a wall 43 of the container 12. Referring to Figure 9, by inserting an inflation needle 36 of a pump 38 into the cylindrical blind passage 30, an end 40 of the inflation needle 36 forces the unattached region 42 (see Figure 5) of the circular rubber sheet 32 into the container 12 to provide the passage 35 for passage therethrough of the inflation needle 36. In passing through the rubber grommet 24 the inflation needle 36 passes into the wadding 20. This results in an outer cylindrical surface of the inflation needle 36 being coated with lubricant.
Withdrawal of the inflation needle 36 from the container 12 results in the unattached region 42 of the rubber grommet 24 resuming its initial position where it seals against the inner cylindrical surface 34 of the rubber grommet 24 (see Figures 7 and 8). After withdrawal of the inflation needle 36 from the container 12 it is lubricated and ready for insertion through a valve of an inflatable article. When the unattached region 42 of the circular rubber sheet 32 is in the closed position of
Figures 7 and 8 it generally seals against the inner cylindrical wall 34 of the rubber grommet 24 to prevent the passage of lubricant through the opening 14 of the container 12.
Referring to Figures 10-14, one example of an inflation needle storage device 43 comprises a cylindrical object 44 which is formed of high density foam rubber and having five bores 46, 48, 50, 52 and 54 which have longitudinal axes that are approximately aligned with a longitudinal axis of the cylindrical object 44. The bores 46-54 extend from an upper end of the cylindrical object 44, entirely through the longitudinal length of the cylindrical object 44 to a lower end. The bores 46-54 therefore exit either ends of the cylindrical object 44 via the upper and lower end surfaces 56 and 58 respectively of the cylindrical object 44.
The bore 46 is a central bore which is positioned within the cylindrical object 44 so that its longitudinal axis approximately coincides with a longitudinal axis of the cylindrical object 44. The bores 48-54 are positioned around the central bore 46 so that the axis of each of the bores 46-54 are substantially aligned and so that each of the bores 48-54 are approximately the same distance from the central bore 46. The bores 48-54 are positioned slightly closer to an outer cylindrical surface of the cylindrical object 44, than the central bore 46.
Referring to Figure 9, the diameters of the bores 48-54 are greater than the diameter of the end 40 (see Figure 9) of the inflation needle 36 and less than the diameter of an enlarged end 60 (which is designed to threadably engage the pump
38) of the inflation needle 36. An inflation needle 36 can be stored in one of the bores 48-54 of the cylindrical object 44 by inserting the end 40 of the inflation needle 36 of Figure 9 into an upper end of one of the bores 48-54. By inserting the end 40 of the inflation needle downwardly, along the longitudinal length of one of the bores 48-54, the enlarged end 60 of the inflation needle 36 abuts the upper end surface 56 of the cylindrical object 44. By applying downward pressure to the upper enlarged end 60 of the inflation needle 36, an upper end of one of the bores
48-54 is resiliently deformed and enlarged. Such deformation of the bore into which the inflation needle 36 is inserted results in the high density foam rubber
material of the cylindrical object 44 contracting around the upper enlarged end 60 of the inflation needle 36 to grip the inflation needle 36 and hold it firmly within the cylindrical object 44.
The diameter of the central bore 46 is greater than the diameter of the bores 48-54 and is designed to enable passage therethrough of the cord 18 of Figure 1. By inserting the cord 18 through the central bore 46 of the cylindrical object 44, the cylindrical object 44 can be slid along the length of the cord 18 until it contacts the clip 19 (see Figure 1) which extends from the cord 18. The cylindrical object 44 is therefore positioned near the clip 19 and football shaped container 12 so that when the cord 18 is positioned around a person's neck, the inflation needle storage device 42 and inflation needle lubricating device 10 hang downwardly.
An object such as a piece of wire having a hook extending from one end which is suitably dimensioned for passage through the central bore 46 may be useful for drawing the cord 18 through the central bore 46.
It will be understood that the invention disclosed and defined in this specification extends to all alternative combinations of two or more of the individual features mentioned or evident from the text and/or drawings. All of these different combinations constitute various alternative aspects of the invention. Various changes and modifications may be made to the embodiments described and illustrated without departing from the present invention.
