Description

Entry door

The invention relates to an entry door comprising a doorframe and a slab. PL 62069 discloses a complete door comprising a doorframe made of jambs and a threshold and a rebated type slab, where the doorframe and the slab are mutually sealed with plastic seals and connected together by means of hinges. The doorframe jambs are made of glued together wooden elements whereas the slab is made of a wooden frame covered with corrugated metal sheeting on both sides and created space between the inner and the outer sheets forming the outer and the inner door skin is filled with polyurethane foam sealant. The doorframe and the slab are sealed with seals embedded in a groove formed in the doorframe and a groove formed in the front surface of the corner cutout in the threshold.

PL 56850 discloses a door slab with enhanced sound insulation. The slab has a rubber seal mounted in the channel, in which one wall is the extension of rebate still around the whole perimeter of the groove.

The object of the invention is a entry door comprising a doorframe and a self- supporting slab hanged on hinges, mounted to the doorframe and consisting of a threshold, lockset, seals and other accessories, characterized in that, the doorframe is formed from a multi-chamber profile, made of PVC and includes inserted metal section and the self-supporting slab, comprises a frame, preferably made of a composite polymer. The frame is covered on both sides with polyester sheeting and the space in-between is filled with CFC-free foam sealant. Both, the doorframe and the slab have at least one groove in which the seal is seated. The doorframe and the slab are constructed and arranged to each other with a gap not greater than 5 mm. The doorframe has a rectangular cross-sectional shape with back surface with protrusions fastened to a door opening, with one corner rounded and/or beveled and the second corner having rectangular channel with embedded masking insert, in which the edge of the slab enters, has, in the front wall of the channel a groove with projections, in which, seal is inserted, which comes in contact with one of the front faces of the slab. Projections on the outskirts of the groove guarantee excellent seal placement in the groove and prevent from seal self-sliding out

The slab is made as a rebated type with the meeting stile on the side, the top, and the bottom edges of the slab. It can also exist as a rebated type on three edges: the upper and the side ones, and as non-rebated on the bottom edge. The meeting stile is carried out within the framework of the slab. In the slab, on the extension of the inner surface of the meeting stile there is a meeting stile groove in which a second seal is pressed in, in contact with the side surface of the doorframe and at the bottom with the side surface of the threshold.

On the lower surface of the slab, parallel to meeting stile groove, there is a second groove in which a brush type seal is pressed in, in contact with the top surface of the threshold. Similarly, on the lower surface of the non-rebated slab there is also a groove in which a brush type seal is pressed in, in contact with the top surface of the threshold.

in the rectangular channel of the doorframe, instead of masking insert, spacer insert is dovetailed containing groove with projections in which seal is inserted. The seal comes in contact with one of the front surfaces of the slab.

The door according to the invention, in which the doorframe is formed from a multi- chamber profile made of PVC with inserted metal section, which adds to rigidity and the slab made as a composite frame covered with flat or corrugated in the respective patterns polyester sheeting with the space between them, filled with foam, which has adequate stiffness and a high degree of mutual fit, with precisely determined gap between the two co-operating elements, which in the product which is subject of that application is up to 5 mm, and in the previously used fusion of a doorframe and a slab greatly exceeded this value. Applied hinges, designed, on the one hand for mounting to the doorframe, made of multi-profile PVC, and on the other to the composite slab, act as permanent suspension and they are not subject to loosening due to long-term use.

However, the most beneficial characteristic of the door combining self-supporting composite slab, that is slab with the composite frame, with the rebated type doorframe according to the invention is implementing of double sealing around the entire perimeter of the slab. Thus, on the top and side edges, with a one seal pressed into a groove in doorframe in contact with the front surface of the slab, and the second seal, pressed into a rebated groove in contact with the side surface of the doorframe. Whereas at the bottom, alternatively, when on the lower edge there is a rebate, then with one seal pressed into the rebated groove in contact with the side surface of the threshold and the second brush type seal pressed in the second groove in contact with the upper surface of the threshold, and in the second alternative, with one seal pressed into the groove in the front surface of the threshold in contact with the front surface of the slab and the second brush type seal, pressed into a groove in the lower surface of the slab in contact with the upper surface of the threshold. This type of seal between the doorframe and the slab ensures high degree of heat and sound insulation.

The implementing of the spacer insert allows, when using the doorframe adapted to the non-rebated slab, installation of the rebated slab on such modified doorframe. The meeting stile of described slab co vers the gap between the doorframe and the slab and has positive impact, first, on the aesthetics but also raises an anti-theft feature.
