POVZETEK

Cilj raziskovalne naloge je bil z merjenji, skiciranjem in foto dokumentiranjem kozolcev na območju Rodice in Jarš spoznati značilnosti vseh štirih tipov kozolcev, ki na tem območju pojavljajo. V nalogi obravnavava enojni stegnjeni Žibertov kozolec, enojni Borčev kozolec s plaščem, dvojni Zalarjev kozolec in Škofičev toplar. Vsi kozolci so zgrajeni iz lesa. Enojni stegnjeni kozolec in enojni kozolec s plaščem imata lesene opore, ki so prislonjene k stebrom prav pod križ. Kozolci so visoki od 3,5 do 4,46 metrov. Okna ali štanti so široki od 4,14 do 4,7 metrov. Vsi kozolci imajo po 12 lat, razen Borčevega, ki jih ima deset. Presledki med latami znašajo 20 do 25 centimetrov. Lesena noga je bila pri vseh kozolcih zamenjana s kamnito ali betonsko. Noge so zakopane v tla in služijo kot podstavek stebru ali pa so vrezane v obliki črke L. K takim nogam so s kovinskimi obroči pritrjeni leseni stebri kozolca, ki se prilegajo zarezam. Noge gledajo 60 do največ 105 cm iz tal. Pri vseh obravnavanih kozolcih so opazni znaki propadanja. Zadnje okno Žibertovega kozolca na zahodni strani nima strehe in je v zelo slabem stanju, zato bi ga težko obnovili. Ostale kozolce bi bilo dobro zaščititi in obnoviti, saj bodo brez obnove kmalu propadli.

ABSTRACT

The goal of our research work was to find out the characteristics of all four types of hay racks in the area of Rodica and Jarše by measuring, sketching, and photo documentation. In our research work a single stretched hayrack, a single hayrack with a cloak, a double hayrack and a bind hayrack have been presented. All hayracks are made from wood. The single stretched hayrack and the single hayrack with the cloak have wooden supports, which lean against the column under the cross. Hayracks are 13.62 - 14.60 feet high, only the Borčev’s hayrack is lower. It is 11.65 feet high. Windows are 13.62 - 15.42 feet wide. All hayracks have 12 laths, with the exception of the Borčev’s hayrack which has 10 laths. The space between the laths is 0.66 to 0.82 feet. A wooden foot was exchanged for a stone or concrete foot. The legs are dug in the ground and serve as a socle to a column or they are cut into the letter L. Wooden columns of hayracks are fixed with metal hoops to such kinds of legs. They fit to the notches. The legs are 1.97 to maximum 3.44 feet above the ground.

All the observed hayracks have decayed. The last window of Žibert’s hayrack lost its roof on the west side, it is in bad condition and therefore it is very difficult to be repaired. Other hayracks should be protected and renewed, or they will dilapidate.
