Construction of climbing holds in sport climbing

Plezalni oprimki, namenjeni dvoranskemu športnemu plezanju, so se vzporedno z razvojem tega športa razvijali skozi obdobje zadnjih tridesetih let. Največja sprememba se je zgodila pri razvoju materiala in oblike oprimkov. V zadnjih letih se panoga razvija vse hitreje, zaradi česar se da razumeti, da bodo potrebe po izdelkih, opisanih v tej nalogi, rastle. Predmet naloge je prikaz konstruiranja in fizične izdelave večjega števila (družine) oprimkov. Naloga je bila izvedena v sodelovanju s podjetjem CST d.o.o., v sklopu praktičnega izobraževanja na fakulteti. V nalogi je predstavljen razvoj dvoranskega športnega plezanja, vzporedno z razvojem materiala in načinom izdelave plezalnih oprimkov. Narejena je bila analiza najbolj priznanih svetovnih in domačih izdelovalcev oprimkov ter analiza njihovih oblik, na podlagi katere so bile izdelane lastne oblike. Predstavljene so lastnosti različnih uporabljenih materialov za izdelavo oprimkov. Opisano je snovanje oblike oprimkov, izdelava osnovnih oblik oprimkov iz pene, izdelava kalupov (negativov) in izdelava odlitkov (oprimkov) iz ustreznega materiala, pri čemer je bila materialna mešanica oprimkov ugotovljena eksperimentalno. Točna sestava v nalogi ni opisana zaradi varovanja podatkov podjetja. V nalogi je predstavljen tudi osnovni preračun lastne cene enega izmed setov izdelanih oprimkov, ki je bil izveden na podlagi podatkov, pridobljenih v podjetju. Končni produkti naloge so seti oprimkov (družina oprimkov), ki jih podjetje že prodaja na trgu pod imenom Victory holds.Climbing holds intended for indoor sport climbing have been developed in parallel with the development of this sport over the last thirty years. The biggest leap occurred in the development of material and shape of holds. In recent years, the industry has been developing faster and faster, which means that needs for the products described in this paper will grow. The subject of this task is to show the construction and physical production of a large number (family) of climbing holds. The task was carried out in cooperation with Slovenian company CST d.o.o., as part of practical education at the faculty. The thesis presents the development of indoor sport climbing in parallel with the development of the material and method of making climbing holds. An analysis of hold shapes of the world\u27s most recognized foreign and domestic competitors was made. This analysis was used as a base for creating our own shapes. The properties of the various materials used to make the holds are shown. The design of the shape of the holds, the production of the basic shapes of the holds from foam, the production of moulds (negatives) and the production of castings (holds) from a suitable material are described, whereby the material mixture of holds was determined experimentally. The exact composition is not described in the thesis due to the protection of company data. The thesis also presents the basic calculation of the manufacturing cost of one set of handholds, by using data obtained in the company. The final products of the task are sets of holds (family of holds), which the company already sells on the market under the name of Victory holds
