Description:
Multilayer anti-slip compact structure for individual/joint application on the forehand and backhand side of the hockey stick blade

Technical Field

Patent invention is related to the composition of the backing carrier and anti-slip layer, which form together a multilayer anti-slip compact structure for individual/joint application on the forehand and backhand side of the hockey stick blade using an adhesive layer. For the above-mentioned reason, the subject matter of this invention belongs to the field of sport games and entertainment, above all collective games using hockey stick and puck or ball.

Background Art

Until now known solutions of hockey sticks and blades gradually developed from prevailing wooden and laminated materials to more modem ones, as for instance aluminium, carbon fibres, kevlar or titanium. All surface treatments of hockey stick and blade have smooth surface. But smooth surface does not provide good puck or ball control during handling, passes and shooting, because puck or ball would slide on the smooth surface. Up to the present known methods for treatment of smooth surfaces of hockey sticks and blades were based for instance on winding round a tape, made mainly from textile or rubber, as proven by the published document US 2,912,245 A. Smooth surface of hockey stick and hockey stick blade could be coarse grained using notches or grooves, or by placement of rubber patch with spikes directly on blade, as proven by the published document CA 1 ,178,983 A. Textile tape, permanently market dominant, have short life span and after partial damage it would be necessary to replace the entire tape. This tape is also very predisposed to catch snow and ice and to get water soaked with the consequence of weight increase and reduction of abilities to handle puck or ball, what we have documented by the published patent file US 4,458,194 with described tape with bristles. Rubber patches are as a rule thicker and heavier than textile tapes and do not provide sufficient increase of coarseness of the hockey stick blade. Their shape and properties at different temperatures could differ, as hockey could be played at temperatures with difference up to 50 °C. The proof of lack of functionality of the existing alternative solutions compared to standard tape for hockey stick is documented by their commercial ill success, because 99 % of players still use traditional textile tape.

From the technology up to the present solutions are also known, in which the coarsening of the hockey stick surface was provided by application of an adhesive layer with content of different firm particles, as described for instance in the Canadian patent file CA984420 and published international patent application WO96/09096 and it is also possible to create this adhesive layer by spraying.

The actual trend of hockey stick producers is represented by permanent reduction of weight of hockey stick, even down to the level of grams. Disadvantages represented by the additional weight in the form of application of hockey tapes or other treatments of the surface, producers of hockey sticks do not have under their control, despite the fact that the additional uncontrolled increase of weight would change the hockey stick balance and properties.

Some documents, as for instance CA21 18740A1 , US6183383, US 3458194, WO 98/40132 (Al), underline only certain properties, which are underlined in the solution according to this invention, what means that they do not follow all important product parameters. The same is valid for other documents, which also address only certain necessary properties, which are underlined in this invention, for example:

WO 97/47365 (Al), which is mainly focused on ridges on control fascia surface and its granularity

WO 2013091079 (Al), which is focused on an idea of friction tape having two different opposing surfaces (adhesive infusion layer and wax infusion layer) GB 547946 (A), which does not specifically address the needs within the hockey game, such as, durability, low weight, improved puck control, thinness, required water resistance and repellency, etc.

- US 4148482 (A), which is focused on the method for fabricating and reinforcing coating for the impact surfaces of hockey sticks using textile tubing

WO 95/1 1 1 1 1 , which does not specifically address the needs within the hockey game, such as, low weight, improved puck control, thinness, required water resistance and repellency, durability, etc.

The purpose of the work of inventors was to design a tape or sticker for covering of hockey stick blade, which would provide anti-slip effect, would be permanent, light and thin, and the result is represented by backing carrier, anti-slip layer and multilayer anti-slip compact structure for individual/joint application on the forehand and backhand side of the hockey stick blade. The resulting product according to this invention should be thermally resistant, water resistant in order that only small volume of ice or snow would adhere to and the adhesive does not leave any residues on the hockey stick, even with good holding to it, but it could be easily removed and replaced. Such complex solution removes disadvantages of solutions as mentioned above in the paragraph on Background Art.

Summary of the Invention

The above-mentioned disadvantages are to a substantial extent removed by composition of the backing carrier and anti-slip layer as such, which form together multilayer anti-slip compact structure for individual/joint application on the forehand and backhand side of the hockey stick blade using an adhesive layer according to the submitted invention. The essence of the invention in composition of the multilayer anti-slip compact structure for hockey stick blades is based on the fact that it consists of the backing carrier and anti-slip layer applied on said backing carrier wherein the backing carrier of the anti-slip layer has two layers. The first layer is formed by a plastic film from polymer with thickness max. 0.3 mm and tensile strength min. 400 N and weight max. 130 g m 2 , preferably from 70 g/m 2 to 130 g/m 2 or fibre/net structure with thickness max. 0.3 mm and tensile strength min. 400 N and weight max. 130 g/m 2 , preferably from 70 g/m 2 to 130 g/m 2 , which contains at least one or a combination of following materials: cotton, viscose, glass fibres, plastic fibres, mainly polyester fibres and textile. On the first layer formed by plastic film or on the first layer formed by the net structure from fibres, the second resin or glue layer is applied, the so-called coating, with thickness max. 0.1 mm containing: polyurethane or polyacrylate or organic resin or polymer. The coating can be preferably applied on the both sides of the first layer, i.e. to the face and reverse side.

It is an advantage for games on ice or outdoors in any weather condition, if the fibre/net structure of the backing carrier of the anti-slip layer for hockey stick blades has a water resistant or water repellent impregnation (treatment) and/or thermal treatment in order to achieve dimensional stability for a broad interval of temperatures.

It is an advantage from the point of view of easy application of the backing carrier of the anti-slip layer on hockey stick blades, if the reverse side of the plastic film or reverse side of the fibre/net structure would have an adhesive layer with thermal resistance from - 15°C to +40°C, which would not leave any residues (adhesive residues) on hockey stick blade.

From the commercial point of view, it would be possible that the second resin/glue layer of the backing carrier of the anti-slip layer on hockey stick blades would be transparent with the purpose of visibility of advertisement placed under that layer, possibly also under the first layer. This semi-product is an extraordinary suitable carrier for the anti-slip layer, possibly a semi -product for a product, if to this semi-product coarse grains are applied.

The related subject matter of this invention representing one inventor's idea represents further the anti-slip layer intended for application on the above described backing carrier. The anti-slip layer is formed by the third resin layer, with thickness max. 0.1 mm and weight max. 250 g/m 2 , preferably max. 100 g m 2 with content of epoxide and/or phenol or suitable polymer. The composition of this third resin layer has the purpose to improve necessary properties of material or anchoring of possible coarse grains. It is advantageous for certain applications, if the third resin layer of the anti-slip layer contains coarse grains, covering max. 50 % of its surface. Furthermore, it is advantageous if the size of these coarsening grains is max. 200 micrometres and their weight is from 5 g/m 2 to 40 g/m 2 . Furthermore, it is possible to coat the third resin layer of the anti-slip layer by a synthetic abrasion resistant layer.

Another option is to apply the above described anti-slip layer directly, this means by individual or joint application on the forehand and backhand side of the hockey stick blade. It is necessary to understand that joint application means bandaging by a tape around the entire hockey stick blade and individual application means attaching the patch on the forehand and/or backhand side of the hockey stick blade.

The above described backing carrier and anti-slip layer represent the basis for creation of the multilayer anti-slip compact structure for individual/joint application on the forehand and backhand side of the hockey stick blade according to the invention, which essence is based on the fact that it consists of the backing carrier and anti-slip layer applied thereon. The multilayer anti- slip compact structure has a shape of a tape or patch. It is obvious that this compact product also has on its reverse side an adhesive layer protected before use by a protective removable covering, coat and film and so on and the adhesive layer would not leave any residues (adhesive residues) on the hockey stick blade. Inventing of the suitable multilayer anti- slip compact structure was achieved exactly by the development of unique combination of materials, of their specific parameters and by finding suitable production process, while the final effect is also represented by improved accuracy and speed of shooting - even by more than 10 %.

The advantages of the backing carrier, anti-slip layer, which together form the multilayer anti-slip compact structure for individual or joint application on the forehand and backhand sides of the hockey stick blade using an adhesive layer according to the invention, are obvious from effects, demonstrated on the outside, h general, it could be stated, that the originality of the submitted solution is based on the fact, that it provides better handling of puck (ball or other objects), more precise passes and shooting. The product is light, thin and extremely resistant to mechanical damage, minimally soaking water and provides higher durability of the coarsened layer applied to hockey stick blade.

This product is an extremely good carrier for possible application of coarsening grains, as well as a suitable carrier for advertisement. This product could be used for all sports types, using a hockey stick. This solution was designed in order to change minimally hockey stick properties from the point of view of balance, flexibility and curvature. This product is easily to apply in order that every player, including smaller children or their parents, would manage product application from a tape of roll, this means by winding round (bandaging) or as a sticker, individually attached to the forehand and backhand side of the hockey stick blade.

Net structure from fibres, forming the first layer of the backing carrier of the multilayer anti-slip compact structure according to this invention could preferably have number of threads in warp and weft (per 1cm) from 15 to 45. Furthermore, this net structure from fibres could have a value of TEX in warp and weft preferably from 15 to 50. Furthermore, this net structure from fibres can preferably have a maximum number of twists (per one meter) 500.

It was agreed for examples 2 - 4 and 6, that the above described anti-slip layers could be also applied without any backing carrier A j directly on the forehand and backhand side of the hockey stick blade, individually, by attaching of two patches of the anti-slip layer or together by bandaging a tape around the entire hockey stick blade.

Example 5

This example of specific realization of the subject matter of this invention describes the multilayer anti-slip compact structure for individual or joint application on forehand and backhand sides of the hockey stick blades. The multilayer anti-slip compact stmcture consists of backing carrier A and anti-slip layer B applied thereon. The backing carrier A with anti-slip layer B applied thereon as product has a shape of tape or patch. By combining examples 1 and 2 a multilayer anti-slip compact structure for hockey stick blade with a backing carrier with fibre net structure and with the simplest anti-slip layer consisting only of resin is formed, as presented in Fig. 5.

By combining examples 1 and 3 a multilayer anti- slip compact structure for hockey stick blade with backing carrier with fibre net structure and resin anti-slip layer containing coarsening grains 6^ is formed, as presented in Fig. 6.

By combining examples 1 and 4 a multilayer anti-slip compact structure for hockey stick blade with backing carrier with fibre net structure and resin anti-slip layer, containing coarsening grains 6, covered by a synthetic abrasion resistant layer is formed, as presented in Fig. 7.

Example 6

This example of the specific realization of the subject matter of this invention describes the second backing carrier A for application of the anti-slip layer B on hockey stick blade, as presented in Fig. 8. This backing carrier A of the anti-slip layer, has two layers. The first layer is formed by a polymer plastic film 1 , for instance from polyester, thickness max. 0.3 mm and tensile strength min. 400 N and weight max. 130 g/m 2 . To this first layer formed by the plastic film the second resin layer 3, with thickness max. 0.1 mm with a content of: polyacrylate is applied. The reverse side of the plastic film I has an adhesive layer 4 with thermal resistance from - 15°C to + 40°C, which does not leave any residues (adhesive residues) on the hockey stick blade.

Another alternative solution provides transparent first layer of the backing carrier A_and the second resin or glue layer 3 of the backing carrier A of the anti-slip layer B for hockey stick blades with the purpose of visibility of advertisement placed under these layers. h the next alternative, it could be possible to consider this semi-product as product, if to this semi-product coarsening grains for instance of corundum, hard plastic and glass and so on would be applied individually or in a combination.
