Description

Method for manufacturing a department store

The invention relates to a method for manufacturing a department store with at least one window that can be opened and closed, wherein a deformable insect screen for retaining insects is arranged between an opening edge bounding the window opening and a window edge.

Such a department store is described in Dutch patent 193434. In the manufacture of the department store described herein, an assembled insect mesh is arranged between the window opening and the window edge, which is pre-processed. This pre-processing of the insect mesh has its effect on the effort required for the production of the department store as a whole, in particular if the total surface area of the window openings to be covered is large. This is mainly caused by the fabrication of the mesh, which is a labor-intensive process and / or requires additional equipment.

The invention has for its object to provide a method for manufacturing a department store of the above-mentioned type, which as a whole is less labor-intensive and / or cost-saving. This object is achieved by covering the window opening during the manufacture of the department store by arranging a non-assembled insect screen between an opening edge bounding the window opening and the window edge.

The invention therefore relates to a method which comprises: (a) providing a department store with at least one window that can be opened and closed 4 no 1 ft 3 β I (b) providing points of engagement along posts and H sill of the window edge and rods and calf of the opening edge I and engaging means, which can engage on it I (c) providing an un-assembled insect gauze and attaching the un-assembled insect gauze along posts and sill of the window edge and I rods and calf of the opening edge by making an engaging connection between engagement points and engaging means, whereby a fixed mesh surface is defined with which the window opening is covered.

(d) providing an elastic tension member and tensioning it substantially in the longitudinal direction of a fold line around the mesh surface, whereby it is at least somewhat narrowed. The method according to the invention has the advantage that it makes use of a non-made insect mesh. That is, an insect mesh on which no functional sewing and / or stitching has been applied, for instance to hold 2 or more mesh parts together and / or to fix them together and / or to serve as a point of engagement for applied elastic pulling means. This simplifies the manufacture of the department store as a whole, since the assembly H is a labor-intensive and expensive H pre-processing.

H In the method according to the invention, the H insect mesh can be clamped between a clamping post H and a clamping frame. It will be clear to those skilled in the art that H also other easily applicable methods for attaching the insect gauze are applicable, such as gluing, the use of a Velcro tape, rivets, and the like.

In addition, it is particularly advantageous to integrate points of engagement, such as clamping posts, in the profiles of the posts and sill of the window edge and rods and calf of the opening edge.

The elastic tension member is preferably placed along the rods and the calf of the opening edge, before the window opening is completely covered with the insect screen. Hereby it is prevented that the elastic tension member is arranged around the mesh surface after the mesh surface has been closed, as a result of which it would be necessary to enter the roof before applying the elastic tension member. After covering the window opening, the tension member can still be tensioned by tightening it and / or slightly shortening its length.

After attaching at least a portion of the insect mesh, it is sized so that the portion that falls outside the attached mesh surface is almost completely removed. By tailoring the insect screen 15 during assembly, the insect screen can be cut off from the roll. Alternatively, the insect screen can be made to measure in advance. This has the advantage that during assembly it is hardly necessary, if at all, to further tailor the insect mesh, which speeds up the assembly.

For the opening and closing of the window, for example, expansion rods may be provided. These expansion rods can engage on intermediate profiles which are arranged between the ends of the window. This prevents the insect mesh from coming into conflict with the expansion rods.

These expansion rods can also engage on the transparent plate of the window, for example by means of hinge supports which are attached to the transparent plate at a distance from each other, for instance because they are glued to this. Here, too, it is preferable if the expansion rods engage at positions within the ends of the window.

1021836 In the method according to the invention, at least one additional elastic tension member, the trigger, can furthermore be arranged on the mesh surface such that a tensile force is exerted therewith, which pulls the mesh surface further into the window opening. The action of the trigger enhances the action of the first elastic tension member. In contrast to the first elastic tensioning member, which is tensioned substantially in the longitudinal direction of a fold line of the mesh, the trigger is attached on one side to the mesh surface and H 10 is tensioned by the other side in an I position within to attach the department store as on the H expansion rods. No H stitching is used as the point of attachment for the attachment of the tractor. This can be done, for example, by applying a clamp which slightly grasps and meshes the mesh. The use of additional elastic pulling members is particularly advantageous if the window opening has a considerable length, such as with a full cam opening. Furthermore, this is advantageous if, when closing the window, the mesh comes into conflict with the expansion rods and / or is clamped between rods and I intermediate posts. The conflict between mesh and expansion rods occurs when the expansion rods engage at positions near or at the ends of the window.

If the window comprises one or more intermediate pillars which coincide with a rod when the window is closed, the mesh becomes caught between the rod and the intermediate column when the window is closed. The trigger promotes that this proceeds in an orderly manner and that the mesh adopts a sufficiently flat conformation to make this possible.

It is, however, preferable in the method I according to the invention to provide a department store, the window of which does not comprise any intermediate posts or the intermediate posts of which do not coincide with the closing of the window when any rods present in the window opening.

If clamping posts and clamping profiles engaging therewith are used, it is furthermore advantageous if in the method according to the invention the clamping strip comprises a condensation discharge channel along the sill of the window. As a result, condensation moisture that condenses against the window surface is discharged to the outside. This prevents the dripping of condensation moisture on the crop, which has a number of advantages known to the person skilled in the art, such as a reduction in the chance of contamination occurring.

The elastic tensioning member can be made in its entirety from a material with elastic properties, such as an elastic, for example made from a material based on silicone. In addition, it can also exhibit only partially elastic properties. A body can be envisaged here, which comprises a cord and one or more springs.

The invention is further explained with reference to the following figures which describe non-limitative examples of the invention.

Figure 1 shows a broken-away perspective view of an opened window of a department store obtained with the method according to the invention, seen through the window of the department store.

Figures 2-5 show cross-sectional details of figure 1 at the positions indicated by arrows II-V.

Fig. 6 shows a unfolded gauze cloth from a department store as obtained with the method according to the invention.

Figure 7 shows the covered window in the open condition of the department store obtained according to the method.

<: -η ·; - 3? The department store 1, which is provided in the method according to the invention, comprises columns (not shown), gutters supported by columns (shown in Figure 7), trusses supported by the I columns, ridge profiles 3, arranged between the gutters and ridge profiles bars 4 and calves placed between the bars 5.

Window openings are present in the roofs of the department store, which are closed by a window that can be opened and closed.

Along the posts 6 and sill 7 of the window edge and rods 4 and calf 5 of the opening edge as shown in figure 1, clamping strips 8 are arranged. Along these clamping strips, the non-assembled insect mesh 9 is arranged by clamping it between the clamping strips 8 and clamping profiles 10, 15 which firmly engage on this. As a result, the insect mesh is firmly and firmly secured along posts 6 and sill 7 of the window edge and rods 4 and calf 5 of the opening edge, as can be seen with H in more detail in figures 2-5.

The insect mesh is unconfined and supplied as a raw material on a roll. It is clamped directly from the roll between the clamping bars and clamping profiles. It is important that the size of the mesh supplied is sufficient to completely cover the window opening.

H Visible is that the insect mesh 9 only has a small H 25 overhanging end on the side where it does not cover the H window opening. This part 15 falls outside the H-attached mesh surface. This is achieved by adjusting the insect mesh H 9 after clamping between the clamping strip 8 and the clamping profile by cutting it off H 30 along the clamping strip. Care is thereby taken that the overlapping end is sufficiently large to ensure that the insect mesh 9 remains securely clamped.

It will be clear to a person skilled in the art that it is possible to first clamp the insect mesh completely around the opening edge and the window edge and then adjust it to size, but that it is also possible to mesh the mesh 5 immediately after clamping between a Customized clamping strip and a clamping profile.

It will be clear to those skilled in the art that the insect mesh can additionally be supplied virtually or completely to size.

It is preferable to clamp the insect mesh with the force of gravity. Preferably a rectangular piece of mesh is clamped from the ridge first along one of the posts 6 and then along the sill 7 and the other post 6 of the window. After this it is clamped along the bars 4 of the window opening, whereafter it is clamped with bars 4 from approximately the center of the calf 5 to the corner points. The folds 20 (Figure 7), which remain in the corners between the bars 4 and the calf 5, are herein preferably folded inwards and clamped firmly and tightly with the rest of the mesh 20. The formed fold is preferably folded inwards so that it can be easily engaged from the inside to be clamped. By making use of this sequence, the mesh can be clamped tightly along the window edge and the opening edge in an easy manner. However, a different order of clamping is also possible.

After the insect mesh is clamped and adjusted to size, an elastic band 16 is tensioned around the mesh surface. Due to the tension on this elastic, the mesh surface 30 is somewhat narrowed and will fold slightly further along the fold lines 17. When the window is closed, the elastic defines a fold line of the mesh and ensures that the mesh is tightly tensioned in the folded state. remains

This reduces wear on the mesh. The elastic is already laid along the opening edge before the insect mesh is clamped, so that it is not necessary to enter the department store deck in order to apply the elastic. Subsequently it is tensioned around the mesh surface by slightly shortening its length and fixing the ends approximately at the height of the cam, for example to the cam brace plate of the department store.

Figure 6 shows in broad lines the shape of the non-assembled insect mesh, as fitted in the window opening of Figure 1. The right-hand part of the mesh is fully explained, while in the left-hand part of Figure I the parts 21 and 22, which at the clamped mesh forms the folds 20, are folded. Part 23 covers the window opening between the sill 7 and the calf 5. Parts 24 and 25 cover the window opening between the bars 4 and the uprights 6.

The mesh can be brought into shape and size in various ways. Among other things by delivering it on a roll and tailoring it after clamping or by supplying the I with the final shape and size. The only important thing is that it is relatively unprocessed because it is unconfined.

I The specific shape and size may vary from case to case. There is also some freedom in this, since the insect mesh is generally flexible and flexible. Figure 7 shows an opened window of a department store obtained with the method according to the invention, viewed from the outside. The insect screen completely covers the window opening, so that both the entry and exit of insects is prevented. The window comprises posts (not shown) which, in the closed state of the window, do not coincide with the rod 18 which runs through in the window opening (not shown). This prevents the mesh from getting caught in the closed state of the window between the posts and the rod 18. The folds 20 are shown in shaded form.
