Description

 The invention relates to sticks, in particular for playing ice hockey.

 A known hockey stick consists of layers of wood glued together and layers of plastic sheet so that the wooden layers of the handle and hook are overlapped (see ed. St. USSR 157248, IPC A 63 V 59/14 , 1963).

 The disadvantage of this club is that with increased loads, there is a high probability of club sticking under shock loads at the junction of glued wooden layers of the handle and hook, which reduces the product's service life.

 Known hockey stick containing a handle connected to a hook consisting of a core and outer plates made of reinforced plastic, in which to prevent delamination, the core of the hook is made monolithic of wear-resistant plastic (see USSR patent 655285, IPC A 63 V 59/14, 1979).

 A disadvantage of the known club is also not a high enough service life, because during operation at the time of increased shock loads, the monolithic core is split.

 Closest to the inventions in technical essence is a hockey stick consisting of a handle and a hook containing a composite core, the front of which is made in the form of a veneer plate, and the back is a conical insert, shortened reinforced plastic plates and long veneer plates (see ed. St. USSR 1785716, IPC A 63 B 59/14, 1993 - prototype for both versions).

 A disadvantage of the known club is the presence of “dead zones” on both sides of the hook (due to the difference in plate thicknesses) at the junction of the shortened plate with a long veneer plate and a reinforced plastic plate opposite the conical insert, which contribute to delamination of the hook during numerous strong impacts. These "dead zones" are practically filled only with epoxy resin and thereby weaken the strength of the club. This circumstance shortens the life of the product.

 The objective of these inventions is to increase the life of the club by increasing its strength properties.

 The task in the first embodiment is solved due to the fact that in a hockey stick with a puck consisting of a handle and a hook containing a composite core, the front part of which is made in the form of a veneer plate, and the back part is a conical insert, plates of reinforced plastic, shortened and long veneer plates, according to the invention, the thickness of the shortened veneer plates at the point of contact with the conical insert disappears, while the reinforced plastic plates are laid on the shortened suspended plates.

 The technical result is achieved due to the fact that the thickness of the shortened veneer plates at the point of contact with the conical insert, vanishing, forms a continuous surface with it. Thus, the difference in thicknesses that created the "dead zone", i.e. weak spot between the plates, which improves the strength properties of the club.

 The task in the second embodiment is solved due to the fact that in a hockey stick with a puck consisting of a handle and a hook containing a composite core, the front part of which is made in the form of a veneer plate, and the back part is a conical insert, plates of reinforced plastic, shortened and long veneer plates, according to the invention, the conical insert has lateral supporting platforms with sides for joining shortened veneer plates on which the plates are laid and h reinforced plastic.

 The technical result is achieved due to the presence in the conical insert of the lateral support platforms with sides, which include shortened plates, forming a continuous surface with the insert. As a result, the difference in thicknesses that created the "dead zone" between the plates is eliminated, which also allows to increase the strength properties of the club.

 Preferably, according to the first and second embodiment, the number of reinforced plastic plates is set to two to four. This is due to the need to manufacture clubs of varying stiffness. Thus, the stick stiffness can be matched to the athlete's individual playing qualities.

 The club in the first embodiment is shown in figure 1.

 It consists of a handle 1 and a hook containing a composite core, in the form of a plate of veneer 2 and a conical insert 3, shortened plates of veneer 4, the thickness of which at the point of contact “a” with the conical insert comes to naught, plates of reinforced plastic 5 and long veneer plates 6.

 The stick of the second embodiment is shown in figure 2.

 It has a conical insert 3 with bearing pads 7 and sides 8.

 An example of a club.

 Preliminarily, on a cutting machine, two blanks of fiberglass are cut down using patterns with special knives.

 On the same machine, two long veneer plates, two shortened veneer plates and one short core veneer plate are cut down.

 For the first option, the ends of the shortened veneer plates attached to the conical insert are milled to nothing at a distance of 40 mm from the edge.

 The length of the long plates is equal to the length of the composite core. The length of the shortened plates overlaps the conical insert by half its length.

 For the manufacture of veneers, wood is used from hardwood and hardwood.

 The conical insert is molded from high-strength material (acrylonitrile butadiene-styrene rubber ABS, grade 2802-E TU 6-05-1578-84) on an injection molding machine or can be made of wood, for the first version with smooth side surfaces, for the second version with supporting platforms and sides on both sides at a distance from the edge of 40 mm with a depth equal to the thickness of the veneer.

 The stick handle blank is made of glued wood battens (GOST 84-76) and plywood boards (PF-X, GOST 8673-83).

 The assembly of the club in both cases is similar.

 To do this, a long veneer plate, one fiberglass plate, a shortened veneer plate (with a milled end for the first option, an unmilled end for the second option), a veneer plate for the core are placed in the template, then a handle pre-bonded with a conical insert from ABS (for the first version made with smooth side surfaces, for the second version - with support platforms and sides), one plate of fiberglass and a plate of long veneer.

 All veneer and fiberglass plates are sequentially impregnated with an epoxy binder in the order of their assembly.

Next, the assembled handle and hook are removed from the template and placed in a hydraulic press, where at a specific pressure of 5-10 kg / cm ² and a temperature of 100 ^o With stand 10-15 minutes until the stick plates of the stick and the hook with the handle are completely bonded.

 The technical result from the implementation of these inventions is expressed in increasing the service life of a hockey stick by increasing its strength properties.
