DE102013017852A1 - Plastic profile bar for glazing or sash frames of windows or doors - Google Patents

Abstract

The invention relates to a plastic profile bar (1) for glazing or sash of windows or doors, with in the longitudinal direction of the plastic profile bar (1) extending chambers (11) or grooves (12), wherein in at least one of the chambers or grooves in a Inserted longitudinal direction of the plastic profile bar insert (21, 21 ') is inserted. The invention is characterized in that the insert (21, 21 ') at least partially consists of a natural raw material. By the invention there is the advantage that with the proposed insert both a gain of the plastic profile bar and a thermal separation is created, whereby the here-observed U-value is abruptly improved.

Description

The invention relates to a plastic profile rod according to the preamble of claim 1.

Profile bars of this type usually have metallic inserts for reinforcing the plastic profile.

The DE 103 19 747 A1 describes such a composite profile, combined plastic and metal. While plastic is a material with low thermal conductivity, embedded reinforcement profiles can ideally absorb the static loads in the load direction.

A disadvantage of this system is that the thermal separation must be done by plastic webs, which means an increased production cost.

Accordingly, it is an object of the present invention to provide a plastic profile bar with which the disadvantages of the known systems can be avoided altogether.

This object is achieved by a plastic profile bar with the features of claim 1.

A created from the plastic profile bar according to the invention window and door element is characterized in claim 11.

Further features of the invention are described in the dependent claims.

According to the invention, a plastic profile bar is proposed for glazing or casement of windows or doors, with extending in the longitudinal direction of the plastic profile bar chambers or grooves, wherein in at least one of the chambers or grooves is used in the longitudinal direction of the plastic profile bar insert.

The plastic profile bar according to the invention is characterized in that the insert at least partially consists of a natural raw material.

By the invention there is the advantage that with the proposed insert both a gain of the plastic profile bar and a thermal separation is created, whereby the here-observed U-value is abruptly improved.

In a particularly preferred embodiment of the invention, it is provided that a reinforcement is embedded in the insert. The reinforcement gives the insert a total stabilization, if the selected material z. B. does not have the desired inherent rigidity.

Preferably, the reinforcement consists of metal. Since the reinforcement is surrounded on all sides by the material of the insert, the reinforcement is encapsulated in such a way that its presence has no negative influence on the U value.

Another particularly preferred embodiment of the invention provides that the reinforcement consists of plastic. The plastic itself has a positive effect on the desired U-value.

Preferably, the insert and / or the reinforcement of a self-rigid material, so that the plastic profile bar is statically stabilized.

In a particularly preferred embodiment, the invention provides that the insert consists of cardboard, corrugated cardboard, cork, compressed wood fibers or bioplastic. Each of these exemplary materials alone is capable of positively impacting the U value. In particular, cardboard or cork have a certain compressibility, so that they can be pressed into the hollow profile both via an opening in the side wall, floor or vertex, and can also be pushed over the end profile opening.

In a preferred embodiment of the invention it is provided that the insert receiving chamber is open on one side thereof. This embodiment makes it possible to press the insert into the chamber. Optionally, this can be used a very highly compressible material that could be used only with difficulty in a frontal insertion.

In a preferred embodiment of the invention it is provided that the plastic profile bar consists of a bioplastic. When profile bar, liner and reinforcement are made from bioplastics and / or natural products, the resulting window or door product is wholly recyclable or biodegradable, with the elements being protected against weathering during the period of use.

In a particularly preferred embodiment of the invention, it is provided that the plastic profile bar a molded off this cover element is molded. Cover element and plastic profile bar connect only a narrow web or a thin skin, so that both parts are easily separable from each other. After the plastic profile bar is equipped with the insert, the corresponding geometry owning cover element can be clipped on or in the profile.

The features of the invention apply to both a plastic profile bar and for a window or door element made therefrom with glare and sash.

The invention will be described below with reference to the drawings based on preferred embodiments. In the drawings show:

1 a cross section of the plastic profile bar according to the invention with molded lid,

2 a cross-section of the closed with the lid plastic profile bar with insert and

3 a cross section of the plastic profile bar with a liner in which a reinforcement is encapsulated.

The plastic profile bar according to the invention 1 is a hollow profile with chambers 11 and grooves 12 , From this, both wing and frame for doors and windows are manufactured with appropriate cross-sectional adaptation. The 1 - 3 show profile cross sections for frame. From a largely rectangular profile part 2 rises on the one hand in a profile longitudinally extending standing seam 3 and on the opposite longitudinal side of a parallel bar 4 ,

While the chambers running on both edge sides 11 . 11 ' are closed hollow chambers, the running in the middle of the profile chamber is open on the bottom side and thus as a groove 12 educated. The bottom opening 9 is on both sides of each pair of parallel bars 5 . 6 / 7 . 8th , possibly even more, enclosed, which in turn each have a groove 14 . 15 limit. Manufacturing technology is a cover element on the main profile 41 molded. This has the corresponding distance to the grooves 14 and 15 two V-shaped protruding spring tongues each 42 . 43 / 44 . 45 that with the jetties 5 . 6 . 7 and 8th are connected. The cover element 41 is separated, for example, by manual deduction of the main profile, the wafer-thin connection between the webs and spring tongues 5 / 42 . 6 / 43 . 7 / 44 and 8th / 45 travels ( 1 ).

After removal of the cover element 41 is the chamber or groove 12 open and can with the deposit 21 be fitted like this in 2 is reproduced. The deposit 21 consists of parallel layers of corrugated cardboard, which over the Bodenöfnung 9 or over the profile end face in the plastic profile bar 1 be pressed or pushed. The deposit 21 can also consist of a compressible material. This expands after insertion or pressing in the profile again. With the lid element 41 the profile is closed by the spring tongues 42 . 43 / 44 . 45 into the grooves 14 . 15 be pressed.

The 3 shows a variant of the invention with an insert 21 ' in a reinforcement 31 is encapsulated. The reinforcement 31 stiffens the profile in total, which is designed cross-shaped. Alternatively, web or x-shaped geometries can be selected.
