Abstract

PURPOSE: To prevent generation of deformation due to pushing load or its own weight by forming a molding member of a plurality of mutually bonded component elements and reinforcing the molding member by an angle-molding member. CONSTITUTION: Ribs are extended along edge-section strip pieces 6 in the vicinity of the insides of the molding member 2 and component elements 2' in the insides of the molding member 2 and the edge-section strip pieces 6 of the component elements 6'. Pushing grooves 7, for receiving reinforced edge sections in the longitudinal direction, are limited in cooperation with the molding member 2 and the component elements 2' at that time. Spaces among the molding member 2 and the component elements 2' and the ribs are set in thickness which are the same as or larger than the thickness of the reinforced edge sections in the longitudinal direction. Consequently, the molding member 2 pushes the end section of the reinforced edge sections in the longitudinal direction into the pushing grooves 7, and can be assembled easily. Accordingly, a rolling-in type shutter and a winding type blind are reinforced, and stability and appearance with respect to mechanical pushing such as the molding member 2 can be ensured.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open cross-section consisting of a plurality of components connected to each other by a single component or an integral hinge, especially for plastic retractable shutters or plastic roller blinds. Molding elements of the type in which the molding element has on the outside along the edge a coupling means for coupling with another corresponding molding element.

[0002]

BACKGROUND OF THE INVENTION Retractable shutters for cabinets in particular, and retractable shutters for window frame closures or frame closures, are generally today made up of male and female components which engage one another.
Popular are single-molded parts which are connected to each other by hinges provided on the longitudinal edges, or molded parts which are composed of a plurality of constituent elements which are connected to each other by integral hinges, in which case two edge parts are used. The elements each have one male and one female coupling means.

Molding members and components are known in the form of hollow or tubular elements or in the form of open elements. Such shaped members and components generally meet the usual requirements, namely that the furniture or window frame is completely closed and opened and is rolled into a relatively narrow space, which is due to the hinge. This is possible by combining constituent elements.

However, if the closure of furniture or the like requires a relatively large length of the forming element, the forming element or element having an open cross-section has drawbacks and the forming element or element is subject to a pressing load. When deformed by itself or by its own weight, this generally impairs the appearance on one side and forms a weak spot such as a retractable shutter on the other side.

SUMMARY OF THE INVENTION The object of the invention is to eliminate the above-mentioned disadvantages of moldings of the type mentioned at the outset.

[0006]

In order to solve the above-mentioned problems, the structure of the present invention is provided with longitudinal reinforcing means.

On the outside, the molding elements 1, 2 have connecting means for joining with another corresponding molding element along the edges and are provided with longitudinal reinforcing means 4. The longitudinal reinforcing means 4 preferably consist of a metal molding and are mounted on the underside of a single piece as the molding 1 or on the underside of at least one component 2 ′ forming the molding 2. For this purpose, a single piece (FIGS. 2 and 3) or at least one molded part
The two component elements 2 ′ are provided with receiving and retaining means 5 for the longitudinal reinforcing means 4.

As is apparent from FIGS. 1 to 3, the receiving and retaining means 5 for the longitudinal reinforcing means 4 preferably consist of ribs, which ribs are a single piece or construction of the shaped parts 1, 2. An element 2'extends inside the edge strip 6 along the edge strip near the inside of the single piece or component and cooperates with the single piece or component to provide longitudinal reinforcement means. It limits the push-in groove 7 for the reception of the four edges.

The spacing between the single piece or component 2'as a molding member and the ribs forming the receiving and holding means 5 for the longitudinal reinforcing means 4, preferably the edges of the longitudinal reinforcing means 4. The same as or slightly larger than the thickness. This allows the molded member to be easily assembled by pushing the end of the longitudinal reinforcing means into the pushing groove 7.

The longitudinal reinforcing means 4 may be formed as a metal molded member having a small elastic deformation degree. As a result, the metal forming member is a single piece or the constituent element 2 '.
Is pushed into the push-in groove 7 and is guided exclusively by the push-in groove at the edges.

In a further development of the invention, a single piece or component 2'as a molding element is preferably provided on at least one end with a sliding skid (Gleitkufe, FIG. 1) in order to avoid friction of the longitudinal reinforcing means 4. (Not shown), the sliding skid being plugged into the end. Forming members or components can be mounted vertically, e.g. in a vertical cabinet closing roll-up shutter (Schrankschl).
iessrollade), longitudinal reinforcement means 4
The only sliding skid provided at the lower end of the forming member or component with suffices is sufficient and friction of the longitudinal reinforcing means 4 in the guide rail of the retractable shutter is avoided.

The molded member 1 or the constituent element 2'is horizontal, for example, a roll-up shutter (Rahmen) for closing a frame.
When used in a schlies rollade, both ends of the forming element 1 or the component 2'are provided with sliding skids, which means that the longitudinal reinforcing means 4 are free to move in the ribs or push-in grooves. And 1
This is because there is a risk of friction with one guide rail or another guide rail.

According to another feature of the invention, the longitudinal reinforcing means 4 may consist of an elastically deformable material.
In this case, the longitudinal stiffening means 4 are pushed from the end into the pushing groove 7 formed by the receiving and holding means 5 (ie limited by the ribs) by gently bending the end, It is installed by releasing the flexure of the end portion after pushing, or by tightening.

In a further configuration of the invention, the longitudinal reinforcing means 4 is constructed as a bent thin sheet or an injection molded piece.

When manufacturing the retractable shutter,
Reinforcement of the retractable shutter is achieved by mounting the longitudinal reinforcing means 4 at regular intervals in the component 2'of the molding element 1 or the molding element 2. In the case of a forming element 2 consisting of a plurality of component elements 2 ', for example one element element 2'of each forming element 2 is provided with a longitudinal reinforcing means (reinforcement forming element) 4 so that a retractable shutter. The regularly distributed reinforcement of is necessarily guaranteed.

In an alternative construction (not shown) of the invention, the receiving and holding means 5 for the longitudinal reinforcing means 4 consist of longitudinal edges, which serve as the forming elements 1, 2. Single piece or edge strip 6 of component 2 '
Extends along the edge of and is bent toward the interior of the open chamber. As a result, the lower part of the edge strip 6 forms a protrusion, which is the longitudinal reinforcing means 4.
Engage within the edges of the to secure the longitudinal reinforcing means to the forming member or component. In this case, the longitudinal reinforcing means 4 have a U-shaped cross section or a square, rectangular or trapezoidal cross section, contacting each edge at the free ends of the two U-shaped legs, Or, it touches both edges on the outside.

In a further construction (not shown) according to the invention, the receiving and holding means 5 is formed in the form of a groove, which groove is in the vicinity of the inside of a single piece or component element 2'as a molding element. Extends along one edge or one holding edge, which holding edge extends along the free end of another edge. Such an arrangement allows the use of angled shaped members as longitudinal reinforcing means.

According to the present invention, it is possible to reinforce a roll-up shutter or a roll-up blind, especially a long roll-up shutter or roll-up blind composed of a molding member, and have good stability against mechanical pressure on the molding member. And in general a good appearance is obtained.
