Description

PL 71 857 Y1 2 Opis wzoru Przedmiotem wzoru uzytkowego jest pólfabrykat do produkcji oscieznic drzwiowych, zwlaszcza oklejanych folia dekoracyjna. Znane i powszechnie stosowane sa oscieznice wykonane z drewna lub drewnopochodnych plyt MDF albo plyt HDF. Zasadniczym mankamentem oscieznic wykonywanych z drewna jest koniecznosc zastosowania drewna o wysokiej jakosci, w sytuacji, gdy, ze wzgledu na walory estetyczne, stanowi on o warstwe licowa oscieznic. Takie rozwiazanie ma jednak wplyw na wysokie koszty wytwarzania takich wyrobów. Z kolei w przypadku, gdy oscieznice wykonane sa z drewna o niskich walorach estetycznych, konieczne jest oklejenie takich produktów folia dekoracyjna, z czym zwiazane sa znaczne problemy technolo- giczne. Z kolei na oscieznice wykonane z plyt MDF lub HDF mozna wprawdzie latwo nakleic folie deko- racyjna, jednakze sa one ciezkie, tak, ze ich waga uniemozliwia niejednokrotnie ich, zgodne z przepi- sami bhp, przenoszenie przez jedna osobe, a ponadto cechuja sie stosunkowo niska wytrzymaloscia mechaniczna, zwlaszcza mala nosnoscia przy wyciaganiu zawiasów, co jest istotne w przypadku oscieznic. Pólfabrykat do produkcji oscieznic drzwiowych, wedlug wzoru, stanowi krawedziak skladajacy sie z rdzenia wykonanego z drewna, o ksztalcie prostokata w przekroju poprzecznym, o grubosci nie mniej- szej niz 20 mm, oklejonego z czterech stron plyta MDF, przy czym od strony dluzszych boków prosto- kata stanowiacego przekrój poprzeczny prefabrykatu, plyta MDF i/lub plyta HDF ma grubosc równa lub wieksza grubosci plyty MDF i/lub HDF doklejonej do rdzenia od strony krótszych boków prostokata sta- nowiacego przekrój poprzeczny pólfabrykatu oscieznicy, przy czym korzystne, stosunek grubosci plyty MDF i/lub HDF o wiekszej grubosci a do plyty MDF i/lub HDF o grubosci mniejszej b miesci sie w prze- dziale: a : b = 1 : 1 do 4 : 1. Pólfabrykat o takiej konstrukcji umozliwia wykorzystanie drewna niskiej jakosci, takze klejonego, na który w bezproblemowy sposób mozna nakleic folie dekoracyjna, a ponadto posiada znacznie wyzsze, w po- równaniu do analogicznych wyrobów wykonanych z plyty MDF i/lub HDF parametry wytrzymalosciowe. Przedmiot wzoru uzytkowego uwidoczniony jest na rysunku, który przedstawia przekrój po- przeczny pólfabrykatu. Pólfabrykat do produkcji oscieznic drzwiowych sklada sie z rdzenia 1 wykonanego z drewna so- snowego, o ksztalcie, w przekroju poprzecznym, prostokata, o grubosci 30 mm, do którego jest, z czte- rech stron, przyklejona klejem POW, plyta MDF, przy czym od strony dluzszych boków prostokata sta- nowiacego przekrój poprzeczny prefabrykatu, plyta MDF 2 ma grubosc a trzykrotnie wieksza niz gru- bosc b plyty MDF 2’ doklejonej do rdzenia 1 od strony krótszych boków prostokata stanowiacego prze- krój poprzeczny pólfabrykatu oscieznicy badz ramiaka. Badania wytrzymalosciowe porównawcze przeprowadzone na pólfabrykatach o analogicznych wykonanych z plyt MDF i drewna oklejonego plytami MDF wykazaly nastepujace wyniki srednie z 4 po- miarów: PL PL PL PL PL PL PL 71 857 Y1 2 Description of the design The subject of the utility model is a blank for the production of door frames, especially those covered with decorative foil. Frames made of wood or wood-based MDF boards or HDF boards are known and commonly used. The main drawback of door frames made of wood is the necessity to use high-quality wood, in a situation where, due to its aesthetic values, it constitutes the facing layer of the door frames. Such a solution, however, affects the high production costs of such products. On the other hand, when the frames are made of wood of low aesthetic value, it is necessary to cover such products with decorative foil, which causes significant technological problems. On the other hand, the frames made of MDF or HDF boards can easily be covered with decorative foils, but they are heavy, so that their weight often prevents them from being carried by one person, in accordance with the health and safety regulations, and, moreover, they are relatively low mechanical strength, especially low bearing capacity when removing the hinges, which is important in the case of door frames. The semi-finished product for the production of door frames, according to the pattern, is an edging consisting of a core made of wood, rectangular in cross-section, with a thickness of not less than 20 mm, with MDF board veneered on all four sides, with the long sides straight - the angle constituting the cross-section of the prefabricated element, the MDF board and / or the HDF board has a thickness equal to or greater than the thickness of the MDF and / or HDF board glued to the core on the side of the short sides of the rectangle constituting the cross-section of the frame blank, with a preferred ratio of the thickness of the MDF board and / or HDF of greater thickness up to MDF and / or HDF of lesser thickness b is in the range: a: b = 1: 1 to 4: 1. A semi-finished product with such a structure enables the use of low-quality wood, also glued , on which you can easily stick decorative foil, and also has a much higher, compared to similar products made of MDF and / or HDF p strength parameters. The subject of the utility model is shown in the drawing, which shows the cross-section of the blank. The semi-finished product for the production of door frames consists of a core 1 made of pine wood, rectangular in cross-section, 30 mm thick, to which is glued on four sides with POW glue, an MDF board, where on the side of the long sides of the rectangle constituting the cross-section of the prefabricated element, the MDF board 2 has a thickness three times greater than the thickness b of the MDF board 2 'glued to the core 1 on the side of the shorter sides of the rectangle constituting the cross-section of the frame blank or the stile. Comparative strength tests carried out on similar semi-finished products made of MDF boards and wood covered with MDF boards showed the following average results from 4 measurements: PL PL PL PL PL PL PL
