Abstract

Door leaf and method of its manufacturing solves problem of lack of proper rigidity of the door leaf on one side, and problem involving in manufacturing and assembly of door leaf on the other side by constructing the door leaf frame of plastic box profile onto which essentially U profile is attached.

Description

DOOR LEAF AND METHOD OF ITS MANUFACTURING
Field of technology
Building and construction; doors; door frames; door leaf.
Technical problem
Technical problem addressed in these specifications is lack of proper rigidity of the door leaf on one side, and problem involving in manufacturing and assembly of door leaf on the other side.
State of the Art
Closest to current specification is EP2581542. It describes the doorstep door leaf has a door leaf frame and door leaf broad sides forming panels. An isolator is arranged between the panels. The door leaf frame is formed to form a metal box profile and a plastic halfshell attached thereto. The door leaf frame is comprised of frame spars having frame spar as metal profile and plastic profile respectively.
EP 1568842 shows different manufacturing methods for known wing-covering designs. In the embodiment shown therein, the insulation and the inner panel of the sandwich panel door panel is cut out, while the motif panel is essentially left as large as the outer broad side of the door leaf, so that only the motif panel rests on the outside of the door leaf frame.
EP1918501 describes inner and outer metallic panels respectively turned towards interior and exterior of a premise, and coupled to a chassis which is formed of two parts movable with respect to each other. The movable parts are coupled together by a thermal bridge rupture unit. The rupture unit has two degrees of freedom along a plane parallel to the panels, and has a plastic profile whose one end is coupled with a guiding clearance in a housing realized on one of the movable parts. An additional part acts as an interface between the rupture unit and an aluminum frame.
EPO 125462 describes the composite profiles from which the frames of a window or door are made or which are used to build a facade consist of a profile rail made of plastic and a profile rail made of metal. When the composite profile is used to build a window or a door frame, the profile rails made of metal face the inside of the room, while the profile rail made of plastic forms the outer shell. The profile rail made of plastic is provided with anchoring webs, which engage with their free longitudinal edges in grooves of the profile rail made of metal. The anchoring webs are fixed in the grooves by molding the outer groove webs and / or the inner groove webs onto the anchoring webs. The profile rails made of plastic are designed with an angular cross section and have outer legs that, in the case of a window or door, stop webs or Form glass retaining strips. The connecting fittings between the sash and the frame and the anchoring fittings for the frame are only attached to the metal profile rails.
EP0022167 describes the door-leaf comprising an outer panel and an inner panel, a body of synthetic material, and also a peripheral frame. For rapid and inexpensive manufacture, a number of these elements are stacked into a press alternately with separation plates, and the insides of the separation plates and the frames are injected with the synthetic material intended to form the body after expansion.
Description of new invention
Door leaf and method of its manufacturing solves problem of lack of proper rigidity of the door leaf on one side, and problem involving in manufacturing and assembly of door leaf on the other side by constructing the door leaf frame of plastic box profile onto which essentially U profile is attached.
For purposes of these specifications metal refers to any kind of metal, for example steel, aluminum, titanium, and further, refers to metal alloys, regardless of coating or covering, and further refers to combination of metals, alloys, or combination thereof. For purposes of these specifications plastic refers to any type of artificial material such as polypropylene, polyamide, PVC, as well as their combination, and further, regardless of coating or covering.
Subject of this invention is door leaf having a door leaf frame and panels forming the door leaf broad sides and having an insulation between said panels, wherein the door leaf frame is formed of a plastic essentially box profile, preferably essentially square or rectangular profile, and metal half-shell; wherein a metal half-shell is connected to to said plastic essentially box profile, wherein the first one of said panels is arranged on the metal half-shell while overlapping a major part thereof, and the second panel is arranged on the plastic essentially box profile while overlapping a major part thereof, wherein said metal half-shell is substantially U-profile shaped with two U-legs, and an U-web interconnecting said U-legs.
Subject of this invention is further insulation arranged between said panels or inside said profiles, or both.
Subject of this invention is further panel, said panel covering entire door leaf, or cover door leaf partially, the rest of door leaf comprising elements chosen from the group consisting of window, glass pane, filling, empty space.
Subject of this invention is further panel, said panel made of metal, sheet metal, smooth metal, wood, simulated wood, plastic, having recesses, having protrusions, or combination thereof.
Subject of this invention is further method for manufacturing of said door leaf profile as described comprising the following steps: providing at least four door leaf frame spars, each door leaf frame spar comprised of at least two door leaf frame spar profiles, - the first of at least two door leaf frame spar profiles is a plastic essentially box profile,
- the second of at least two door leaf frame spar shells is a metal half-shell, forming each door leaf frame spar by connecting said metal half-shell to said plastic essentially box profile, attaching said door leaf frame spars to each other to form door leaf frame, attaching panels to said door leaf frame spars.
Subject of this invention is also method comprised of further step of filling in at least one profile, at least partially with insulation.
Subject of this invention is also method comprised of further step of reinforcing the corners of said door leaf frame with comer brackets of arbitrary material, preferably either metal or plastic, depending on the situation and decision of the designer.
The invention provides for doors having door leaf, said door leaf provided with side panels attached to door leaf frame. This door leaf frame is comprised of door leaf frame spars, and they are in turn comprised of at least two profiles, the first of which is plastic profile of essentially box cross section and the second of which is a metal half-shell connected to said plastic profile.
It is customary in state of the art that the door leaf frame is comprised of either two box profiles or two half-shells. Two box profile is problematic as they are hard to attach, or even hard to slide one onto another. Two half-shell is problematic as it is less rigid that two box profiles causing the doors to buckle under specific loads. Further, two half-shell system is problematic during manufacturing requiring sliding both half-shells one to another if tongue-and-groove attachment is provided.
The solution is to create one box profile connecting to half-shell.
In principle it would be possible to have a metal box profile onto which plastic half-shell is attached. However, such solution would mean necessity for additional reinforcing webs as the plastic is not of high enough strength. On the other side, if plastic half-shell is thicker, hence more load bearing, it is not possible to simple snap-on it in place. Hence plastic half-shell, is possible, but not advantageous.
It is advantageous to have plastic box profile which may be equipped with tongues, attachment points or similar to provide for snap-on connections between said plastic box profile and said metal half-shell. Once tool for plastic moulding is created, the cost no longer depends on complexity of the plastic box profile.
On the other hand, metal half-shell is flexible and provides for appropriate snap-on connection to tongues, recessions, attachment points or similar hence sliding one profile onto another is no longer necessary.
Metal half-shell is therefore formed in such a way that it forms essentially U profile with two U-legs wherein each of U-leg on distal point attaches to said plastic essentially box profile, and with reinforcing U-web interconnection between both U legs. Points of attachment can be continuous, or intermittent depending on connection type.
It is also possible to attach both profiles one onto another with other types of attachment such as screws, rivets, adhesives or similar but snap-on attaching is preferred. Not only that, tongue-and-groove arrangement can be provided for conventional sliding the profiles one onto another if existing manufacturing facilities are to be used, and converted.
The panels can be attached to said profiles, first of said panels arranged onto said plastic box profile, and second of said panels arranged onto said metal profile, said panels largely covering each of respective profiles. Form of attachment can vary from applying adhesive to using screws, rivets, welding, spot welding or other type of attachment as known in state of the art.
It is also advantageous to have said door leaf with improved insulation. The energy prices increasing, and entry into building forming more and more livable part of the living quarters it is advantageous to have inner panels at as close as temperature to other inner parts of the living quarters as possible. This can be made possible by insulating the door leaf. If the door leaf is to be comprised also of a window, only space between the panels will be insulated.
The insulation further improves the stability and the rigidity of the door leaf.
The panels can be made of plastic, metal, wood, artificial wood, or any other material suitable for dressing-up the door leaf.
The doors in question can be equipped with magnetic holder, magnetic strip or similar magnetic device in order to provide for attachment point for Christmas decorations or similar, on the inside of said panels if said panels are made of non-magnetic metal or non- metal materials.
The panels can be either smooth, or made with protrusions and depressions as to mimic naturally rough surfaces or to provide for coverings of said panels.
