Definitions

  • This invention relates to footballs and is more particularly concerned with a football of the type having an outer cover of leather or synthetic plastics material such as a laminate with an internal inflatable bladder.
  • the invention is primarily but not essentially concerned with footballs having an ovoid shape such as those use in playing the game of rugby or American football.
  • the inflation tube and valve form an assembly usually circular in plan form with a flange by which the assembly may be adhesively connected with the bladder.
  • the valve assembly and flange has hitherto been made as light and small as possible in the belief that there should be as little interference as possible with the symmetry of the bladder.
  • a football comprising an outer covering and an inner inflatable bladder with an inflation tube and valve assembly located on a surface of the bladder with the inflation tube passing through an aperture in the cover of the ball, the assembly being characterised by a relatively massive reinforcing structure, in terms of weight, surrounding the inflation tube and valve and forming a weighting means being a significant weight in relation to the overall mass of the ball and bladder assembly.
  • the asymmetrical mass formed by the inflation tube and valve assembly should be of the order of 50 grammes or greater.
  • the weight may be between 30 and 150 grammes where the bladder material and the ball cover is of customary proportions and weights.
  • the actual weight is defined by the size and characteristics of the ball the overriding feature being that the valve assembly zone of the bladder, or the ball, is made with a significant weight in contrast to known teaching which provides for this zone to have minimal weight.
  • This constructional feature provides an imbalance when the ball rotates, particularly end over end as when place kicked.
  • this may be achieved by providing a flange surrounding the inflation tube which upstands from one surface thereof, the inflation tube connecting with a valve assembly located in, or projecting from, the other surface of the flange.
  • the flange itself is defined by a relatively thick cylindrical protrusion with a peripheral feather edge by which it may be adhesively secured to the surface of the bladder.
  • the cylindrical projection may incorporate a weight, for example a thin, dense metal or plastic material serving also to form a reinforcement.
  • there may be embedded in the surface zone of the cylindrical projection, a woven material which projects partially from a surface thereof, this material forming both a weighting means and a reinforcement and non-slip area which locates the bladder more securely within the cover.
  • the inflation tube is arranged to pass through an aperture in a seam between portions forming the cover and where the cover is joined by intumed stitched or otherwise connected edges.
  • the cylindrical portion will include, on an upper surface thereof, a channel which is adapted to receive the inturned sewn edges of the cover, thereby providing for the cylindrical projection on its upper surface to be in intimate contact with the adjacent internal cover surfaces.
  • the surface of the cylindrical projection will be curved in two mutually right-angular directions thus forming a domed top surface which substantially conforms with the internal curvature of the cover when the bladder is inflated.
  • a further feature of this invention provides for a reduction in the thickness and hence weight of the outer covering and possibly also the thickness and weight of the bladder material itself. Such a reduction in many cases would result in the ball being destroyed around the area which is weakened by the valve assembly in the bladder and this is avoided in the present invention by making the valve flange and cylindrical part relatively large in diameter and of a substantial thickness and hence mass.
  • this invention contemplates moving the mass of the ball from a symmetrical distribution to a more off-centre distribution where a greater portion of the mass is concentrated at the valve assembly which is thereby reinforced in order to afford good durability.
  • Figure 1 shows a side view of the bladder valve assembly and two joined sections of outer cover of a ball
  • Figure 2 shows the inflatable bladder with the valve assembly in plan view
  • Figure 3 shows a section on III of Figure 2
  • Figure 4 shows a section on IV of Figure 2.
  • a football in this instance a rugby football of ovoid shape, comprises four outer panels which are sewn together along longitudinally extending seams and in Figure 1 the edge portions of two such panels 1a and 1 are shown joined along a seam 3 conventionally by internally located stitching.
  • a small orifice is provided at a centrally disposed location along the seam and through this orifice a small inflation tube or nipple 5 projects, this forming the point of inflation 2 for the ball.
  • an inflatable bladder 6 ( Figure 2) which has a valve assembly connected therewith, this assembly being generally referenced 4.
  • the inflation tube or nipple 5 connects with a valve block 5a being of a relatively massive construction and when inflation air is applied through the tube 5 the valve block 5a opens up along a split seam 5b, thus allowing air to enter the bladder.
  • a valve block 5a Surrounding the valve block 5a is an internally projecting cylindrical portion 4a which lies beneath the surface of the bladder 6.
  • the cylindrical portion 4a connects with a flange which extends laterally and overlies the outer surface of the bladder.
  • the flange has a relatively massive cylindrical projecting portion 4b with a peripheral feather edge 4c by which the valve assembly may be adhesively connected to the bladder 6.
  • a textile material 9 is provided which is partially embedded into the surface of the valve member and which provides a weighting means as well as a high friction surface to contact the internal surface of the covers 1a and 1b.
  • the upper surface of the cylindrical projection 4b is curved as shown in order to provide good surface contact with the inner surface of the cover parts 1a and 1b.
  • valve assembly As previously mentioned one of the features of this invention is the provision of a relatively large off-centre mass which is conveniently defined by the valve assembly as shown.
  • This assembly may be formed from a relatively dense rubber material similar to the material used for the bladder itself.
  • a more dense material may be embedded into the valve assembly and this is illustrated in Figure 3.
  • the material which for example may be a metal, is embedded in the form of strips W1, a ring W2, or a cylinder W3.
  • the weighting means W1 , W2 and W3 may be used in combination or singly according to the overall mass desired.
  • the valve assembly of this invention can equally be used to provide the off-centre mass giving the advantages which accrue therefrom.
  • the channel 7 would not be essential as there would be no need to receive the inturned edges of the stitched seam.
  • the valve assembly is made relatively massive in order to provide the necessary offset mass. If use is made of metal or other dense weighting means then a further embodiment contemplates a reduction in the size of the valve assembly and in such a case the cylindrical portion 4 could be reduced in size whilst still allowing for the inturned edges at the seam to be accommodated, for example by providing a more internally recessed channel.
  • the weighting means may comprise a plate member suitably profiled and located between the valve assembly and outer cover and forming also a reinforcement protecting the valve. In another embodiment this plate is located within the bladder around the valve and adjacent the internal bladder surface. Such constructions provide a more rigid area around the valve assembly with less bulk.

Abstract

Afin d'améliorer les propriétés balistiques d'un ballon, généralement un ballon de rugby, un ensemble valve de gonflage (4) relativement volumineux est placé sur une poche gonflable (6). Cet ensemble (4) peut comporter des poids de métal ou de plastique (W1, W2, W3), et/ou un mat textile dense (9), qui constitue un poids supplémentaire. Un canal (8) s'étend le long de la surface extérieure dudit ensemble (4). Des coutures tournées vers l'intérieur de pans de couverture contigus peuvent se loger dans ce canal, l'embout de la valve (5) pouvant ainsi faire saillie à travers la couture du ballon. Etant donné le poids important de l'ensemble valve dans la couture du ballon, celui-ci suivra une trajectoire améliorée lorsqu'il sera frappé du pied en un point situé sur la couture opposée à ladite valve.
