BREVE DESCRIPCIÓN DE LA INVENCIÓN La disposición geométrica para la confección de una semiesfera protectora para gorras de golf que la invención propone incorpora una pluralidad de características novedosas en relación a otros elementos utilizados dentro del sector y que resuelve problemas que hasta ahora eran complicados de resolver. De una forma más precisa diremos que para definir el material y forma y para establecer las condiciones de ensayo de los materiales fue necesario conocer la energía de impacto de una pelota de golf en diferentes condiciones BRIEF DESCRIPTION OF THE INVENTION The geometric arrangement for making a protective hemisphere for golf caps that the invention proposes incorporates a plurality of novel characteristics in relation to other elements used within the sector and that solves problems that until now were difficult to solve. In a more precise way we will say that to define the material and shape and to establish the test conditions of the materials it was necessary to know the impact energy of a golf ball under different conditions
Para ello se calcularon las velocidades de impacto a partir de un golpe a altas velocidades. Se consideraron dos ángulos de salida de la pelota, 11° y 15°, y velocidades de hasta 250 km/h. For this, the impact speeds were calculated from a blow at high speeds. Two ball exit angles were considered, 11 ° and 15 °, and speeds of up to 250 km / h.
A partir de los resultados y del conocimiento del peso de una pelota de golf reglamentaria se pudieron conocer las energías de impacto. Las siguientes tablas y gráficos ilustran los resultados. From the results and the knowledge of the weight of a regulation golf ball, the impact energies could be known. The following tables and graphs illustrate the results.

Como se puede observar el valor máximo de energía de impacto se sitúa en torno a los 20J, por lo que se marcó como límite máximo para los ensayos. Para conocer si los resultados de los ensayos demostraban la viabilidad del material para cumplir el objetivo establecido se analizaron otros ensayos estandarizados como referencia. As can be seen, the maximum impact energy value is around 20J, which is why it was set as the maximum limit for the tests. To find out if the results of the tests demonstrated the viability of the material to meet the established objective, other standardized tests were analyzed as a reference.
Se tomó como referencia el Certificado CE EN397 - Cascos de protección para industria. En los ensayos correspondientes el casco debe ser capaz de absorber un impacto de unos 50J lo suficiente como para que la fuerza transmitida al portador del mismo sea menor de 5kN. The CE EN397 Certificate - Protective helmets for industry was taken as a reference. In the corresponding tests, the helmet must be capable of absorbing an impact of about 50J enough so that the force transmitted to the wearer is less than 5kN.
Estos 5kN se marcarán como límite máximo de la fuerza que el material debe transmitir al jugador de golf ya que se consideran suficientes como para no causarle lesiones de importancia. These 5kN will be marked as the maximum limit of the force that the material must transmit to the golfer, since they are considered sufficient not to cause serious injuries.
En el documento “PV1901240-lnforme.pdf” remitido y firmado por el ITMA, entidad que llevó a cabo los ensayos de impacto, se recogen las condiciones y resultados de los ensayos. En las conclusiones del mismo dice: The document "PV1901240-lnforme.pdf" sent and signed by the ITMA, the entity that carried out the impact tests, contains the conditions and results of the tests. In the conclusions of the same it says:
1.- Todas las muestras soportan un impacto de 20 J con una carga máxima inferior a1.- All samples withstand an impact of 20 J with a maximum load less than
5 kN. 5 kN.
2.- Los resultados obtenidos son independientes de la cara de impacto y del lugar donde impacten las muestras dentro de la probeta ensayada.
Para obtener la forma semiesférica del protector a partir de una plancha de 5mm de grosor se utiliza un corte no total de forma que los lóbulos se encuentren unidos estaban por el vértice más agudo, formando una suerte de estrella. 2.- The results obtained are independent of the impact face and the place where the samples impact within the tested specimen. To obtain the hemispherical shape of the protector from a 5mm thick plate, a non-total cut is used so that the lobes are united at the sharpest vertex, forming a kind of star.
Este diseño asegura la continuidad estructural en la zona de la coronilla y una mejor colocación del protector dentro de la gorra. This design ensures structural continuity in the crown area and a better placement of the protector inside the cap.
El perímetro de la cabeza fue el parámetro usado para calcular el resto de las cotas, lo que ha permitido diseñar patrones para un rango amplio de tamaños basándonos en las mismas ecuaciones. The perimeter of the head was the parameter used to calculate the rest of the dimensions, which has allowed us to design patterns for a wide range of sizes based on the same equations.
Además este diseño tienen una gran versatilidad, ya que permite colocarlo en una gorra, entre la superficie textil y superior y el forro interior y dejarlo fijo, pero también permite de una forma sencilla extraerlo de una gorra y colocarlo en otra. In addition, this design has great versatility, since it allows it to be placed in a cap, between the textile and upper surface and the inner lining and to leave it fixed, but it also allows in a simple way to extract it from one cap and place it in another.
E incluso permite colocarlo directamente sobre el interior de cualquier gorra y después de utilizarla durante un partido quitarla para que la gorra sea más cómoda. And it even allows it to be placed directly on the inside of any cap and after using it during a match, remove it to make the cap more comfortable.
