FLOOR HOCKEY PUCK
BACKGROUND OF THE INVENTION
This invention relates to a floor hockey puck.
It is well known that such pucks comprise a disc generally of about three inches diameter and one inch in height with edges that can be bevelled to a slight extent sufficient to reduce rolling of the puck on the floor and to help the puck lie flat as it travels across the floor. The defini-tion of puck referred to herein is intended to comprise merely disc-shaped objects of this general type and to ex-clude such other projectiles as balls, rings and the like.
Floor hockey attempts to simulate ice hockey while providing a sport which is less injurious to health.
Thus, the puck itself must be designed so that its move-ment on a suitable floor simulates movement of the icehockey puck on ice. Thus, it has a number of specific re-quirements which the ideal puck should meet in order to make it satisfactory for use in a floor hockey game. Spe-cifically, therefore, the puck should provide the follow-ing properties:1. It should have a low co-efficient of restitution so that it is resistant to bouncing on the floor surface.

3. It should be resistant to damage caused by com-pression or stress by contact with one or more hockeysticks, the floor and feet of the players.
4. It should have the correct degree of resilience to enable it to be moved under control of the stick of a player including that it must be sufficiently hard to al-low for a "crisp" shot.5. When used for children or merely for recrea-tional purposes, it should be soft enough to avoid bodily harm when contacting a player at the considerable velocity developed in shooting. For use with a more vigorous game, this requirement may be sacrificed to produce a puck which is more suitable for shooting and handling.
6. The flat surfaces of the puck must be such that it can slide smoothly across a smooth floor surface.
Conventionally, pucks are manufactured by moulding from a resilient material such as hard plastics ' to provide or rubber, but these have failed/enough of the requirements stated above for floor hockey to become accepted widely as a sport.
SUMMARY OF THE INVENTION
It is one object of the invention therefore to provide a floor hockey puck manufactured in a manner which enables it to satisfy many of the above characteristics.
According to the invention therefore there is provided a floor hockey puck formed contiguously from at least two distinct portions wherein at least one of the portions is formed of a first material and at least one of the portions is formed of a second material having dif-ferent physical properties from the first.
It is one advantage of the present invention that it can be formed of a first dense incompressible mate-rial which provides the mass and smooth sliding character-istics and a second softer resilient material which can be used to provide the resilience of the puck to avoid or reduce bodily harm on contact.
It is a second advantage of the invention that it can be formed from two strips of material, the first strip being formed of a hard dense incompressible material and the second strip being formed of a softer more resi-lient material with the strips together being rolled co-axially of the axis of the puck.
It is a yet further advantage of the invention that it can be formed of flat plates of the material so that the harder material forms the flat surface of the puck sand-1209~ US
wiching~an inner layer of the softer resilient material.
It is a yet further advantage of the invention that the second resilient material can be formed from a fibrous textile material.
With the foregoing in view, and other advantages as will become apparent to those skilled in the art to which this invention relates as this specification pro-ceeds, the invention is herein described by reference to the accompanying drawings forming a part hereof, which includes a description of the best mode known to the applicant and of the preferred typical embodiment of the principles of the present invention, in which:
DESCRIPTION OF THE DRAWINGS
Figures 1 to 9 show schematically different em-bodiments of a floor hockey puck manufactured from two different materials.
In the drawings like characters of reference indicate corresponding parts in the different figures.
DETAILED DESCRIPTION
Generally, the invention relates to a puck manufactured from two different materials so that the materials remain distinct in the finished object. This is different from a moulding or casting process wherein the two materials merge so they become indistinguishable 1~09165 in the finished puck so that their physical properties merge.
One of the materials is generally of a hard or incompressible material which provides properties of high density, high resistance to wear, low co-efficient of friction relative to the floor surface, and generally of a substantially incompressible nature. Hard plastics material can provide suitable properties for the hard material portion of the puck in addition such materials as canvas, thin leather, leatherette, vinyl-fibreglass combination, non-elastic rubber, compressed felt and vinyl plastic can be satisfactory.
The other material, in comparison with the first material, provides properties of softness and flex-ibility so that it can have less density, more compressi-bility, more resilience than the first material. Examples of such soft materials can be provided by any fibrous tex-tile material including felt, wool, Velcro (registered trade mark) which provide a soft material texture giving resilience to the finished puck which provides the pro-perties defined above and particularly reduces the possi-bility of bodily harm on contact with a fast moving puck.
The hard material thus is of such a density relative to the soft material that its purpose is to add 1209~6S
mass and body to the puck. The soft material in con-trast is of such a density and flexibility relative to the hard material that its purpose is to make the puck flexible to contrast the hardness of the first material and to balance out the puck.
Turning now to the drawings, Figure 1 shows a preferred embodiment of the puck which is formed from the construction of Figure 2. Specifically, the puck is formed from a strip 1 of felt material which is flexible, resi-lient, compressible, and of relatively low density connect-ed to a strip of canvas which, in comparison, is less com-pressible, less resilient, more dense and more resistant to wear. The two strips as shown in Figure 2 are connected together by stitching with the felt strip being wider and longer than the canvas strip so that it has edges over-lapping the canvas strip and one end of several inches long extending beyond the end of the canvas strip or one side of the canvas is longer than the other canvas strip or felt strip. This larger canvas can be rolled up for the core also.
As shown in Figure 1, the puck is formed by roll-ing the strip of Figure 2 about the axis of the puck with the free portion of felt rolled at the middle of the puck to form a felt core. The strip is rolled in the direc-1~209~65 , 7 tion such that the canvas forms the outermost layer of thepuck. The rolled strip is then secured by stitching or binding so that the centre does not lift out of the plane of the puck and so that the exterior end is securely re-tained. Such securement can be obtained by glueing, sew-ing, stapling, tying or binding, fusing the materials toge-ther by heat or by the use of mechanical connectors such as hooks or staples.
In an alternative arrangement, two canvas strips are attached to respective sides of the felt strip with one of the canvas strips extending beyond the other strip, to be rolled into a core of the puck.
To provide a heavier, less resistant puck more suitable for a more vigorous game where skill and accuracy are more important than injury, the central core of the puck of Figure 1 or the above described alternative can be hardened by the application of a settable liquid such as a thermoplastic resin or shellac.
To allow the puck to be used outside, it should be rendered resistant to water by a coating on or impregna-tion of the textile materials since freezing of any water within the puck would affect its weight and resilience characteristics.
Turning now to Figure 3, the puck is manufac-1209~65 tured from alternate layers of the soft and hard materials as defined above with a hard core 3 at the centre and the others layers 4, 5 lying co-axially around the soft core.
The outermost layer is a hard layer to provide an edge of the puck which is better for stick handling and shooting purposes while the soft inner layer allows the puck to be less damaging in high speed contact with persons or pro-perty.
The embodiment of Figure 4 is a simplified ver-sion of that of Figure 3 comprising only two layers, thatis an inner core 6 of hard and dense material and an outer layer 7 of the softer material. In this way, the core at the centre is embedded in the soft material for the pur-pose of increasing the weight of the puck while the resi-lient more compressible outer material provides the mainbody of the puck which generally comes into contact with the sticks and people involved.
Figure 5 shows an embodiment incorporating a number of different layers as shown in Figure 3, but in ~209165 this case the layers are arranged in planes at right an-gles to the body of the puck thus together providing the necessary properties as defined above.
In Figure 6 is shown a yet further embodiment wherein hard and soft fibrous textile portions are com-bined and then moulded or compressed into a puck form. A
binding compound such as resin can be used to hold the fibrous portions together into the required shape.
Figures 7 and 8 show yet further embodiments wherein the hard and soft materials are arranged in layers the planes of which are parallel to the plane of the puck.
Thus, the hard material forms layers 8 on the outside of the puck providing the upper and lower flat faces of the puck which contact the floor. The central or sandwiched layer 9 is formed of the soft material.
Figure 8 differs from Figure 7 in that the two outer layers are connected by a central core to assist in retaining the integrity of the puck. In this way, the hard materials provide smooth sliding surfaces on the top and bottom of the puck as well as the necessary mass or weight. The soft inner material extends slightly beyond the edges of the hard material so as to form substantially alone the edge of the puck which in use will contact the stick or person. The bevelled edges of the puck are shown in Figures 7, and 9 which assist in preventing rolling of the puck and also reduce the sharpness of the edge which could otherwise be particularly dangerous.
The embodiment of Figure 9 comprises a similar structure to that shown in Figure 4 with a central core 6 of the hard material and an outer layer 7 of the soft material except that additional cylindrical core pieces 10 extend through the outer soft material at angularly spaced locations. The cores of hard material extend through the soft material so as to stand proud of the flat faces thereof so as to provide the smooth sliding surfaces for contact with the floor.
Since various modifications can be made in my invention as hereinabove described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
6. The flat surfaces of the puck must be such that it can slide smoothly across a smooth floor surface.
Conventionally, pucks are manufactured by moulding from a resilient material such as hard plastics ' to provide or rubber, but these have failed/enough of the requirements stated above for floor hockey to become accepted widely as a sport.
