Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is formed from a hollow profile member having a hollow portion for accommodating a granular moisture-absorbing material, and the hollow profile member is interposed between glass plates and surrounds the glass plates. The present invention relates to a spacing frame for glass plates, which forms an internal space between the glass plates, and has a wall portion in contact with the internal space with a communicating portion between the hollow portion and the internal space.

(Prior Art and Problems to be Solved by the Invention) Many types of spacing frames for glass plates are known. These are usually made of light metal profiles. These molding materials are cut according to the length of the sides of the frame, and then the frame is joined at the corners of these individual moldings. Special corner fittings or corner pieces are used at the corners. Furthermore, at the corners, the ends of the respective shapes are joined together by butting each other or by cutting them diagonally. What these frames have in common is that they are all made of hollow profiles. The hollow parts of these profiles are used to house moisture absorbing materials marketed by the relevant industry in the form of small spheres. The moisture absorption material acts on the interior space between the glass panes through the slits or hole arrays in the hollow profile. The above-mentioned corners of such a spacing frame, whether formed by butting profiles, diagonally cut connections, or using corner fittings, are the weak point of the glass plate holding frame, and are especially They require careful assembly, and even when assembled carefully, they often receive complaints. This applies in particular to glass panes that are exposed to extreme atmospheres (eg indoor swimming pools or industrial buildings).

According to German Patent Publication No. 2160847 2
An insulating glass pane unit is shown comprising one or more glass panes with spacing between them. In this case, the interface surfaces are joined to each other with plastic material, and the spacer serves to accommodate the moisture absorption material, which acts on the interior space of the insulating glass pane unit through the holes in the holder. The glass plates are held together by a rigid profile crosspiece that forms the spacer at the center and surrounds the glass plate holding groove at its protrusion. The profile bar has a U-shaped cross section and is provided with a central hole in its central portion which acts as a spacer. To assemble this insulating glass plate unit, the glass plates are fitted into the respective outer grooves, and then the side portions forming the grooves are pressed against the glass plates. This assembly structure was not really popular. That is, in order to properly seal the parts together, the projecting parts of the outer parts must be pressed against the glass plate. It is common for the glass plate to break due to pressurization or roller application of this projecting portion. In order to form a spacing frame in this known construction, a continuous profile bar of the above-mentioned shape is placed at the corner of the frame to be made with a V.
A shape is cut into the shape, and each adjacent section thus created is folded into each other. Each V-shaped cut extends to the bottom of the profile rung, so that the profile rung is effectively cut over its entire height at the corner, resulting in the known beveled connection.

Such a method would undoubtedly be successful if there were no moisture-absorbing material in the central hollow part of the spacing frame in the center of the profile. However, as soon as the V-shaped cut is made and the profile bar thus prepared is handled for the fabrication of a frame, the contained moisture absorbing material in the form of globules spills out. By the time the frame is closed, this granular moisture absorbing material has already flowed out. However, in today's state of the art, frames without hygroscopic material can no longer be used as insulating glass pane units. For these two reasons, the known methods as described above could not be widely used.

(Object of the Invention) The present invention is a space for glass plates that is constructed so that a hollow profile filled with a granular moisture-absorbing material can be bent into a frame without requiring a V-shaped diagonal cut, which is known and cannot be used in practice. The purpose is to provide a holding frame.

(Means for Solving the Problems) In order to achieve the above object, the holding frame for a glass plate of the present invention is formed from a hollow shape material having a hollow part that accommodates a granular moisture absorbent material, and the hollow shape material is formed between the glass plates. a spacing frame for glass plates, which is interposed between and surrounds the glass plates to form an internal space between the glass plates, and has a wall portion in contact with the internal space with a communication portion between the hollow portion and the internal space; The hollow shaped material has a cut in the wall portion having a width along the longitudinal direction of the hollow shaped material with a dimension equal to or less than the particle size of the moisture absorbing material and a depth approximately equal to the thickness of the wall surface portion. A corner portion is formed by providing the hollow member along the width direction and bending the wall surface portion with the notch facing inward.

(Operations and Effects) In the glass plate spacing frame of the present invention, the hollow shaped material has a width along the longitudinal direction of the hollow shaped material with a dimension equal to or less than the particle size of the moisture absorbing material in the wall surface portion, and is approximately equal to the thickness of the wall surface portion. Corners are formed by making deep notches along the width of the hollow material and bending the wall surface with the notches inward, so when filling the hollow material with moisture absorbing material. Also, it is possible to prevent spillage to the outside when forming the corners. Furthermore, since the connecting portion of the hollow profile can be provided in a straight line portion where the connecting work is easy, the glass plate spacing frame can be manufactured quickly and easily.

(Example) Next, an example of the present invention will be described with reference to the attached drawings.

Figure 1 shows a cross section of the edge of the spacing frame for insulating glass plates, where glass plates 1 and 2 are connected to light metal sections 2 and 3.
They are separated from each other by a frame 3 made of 0. 1st
The shape material 20 itself shown in the figure is publicly known. A slit 5 (see FIG. 13) is provided in the wall surface 4 of the profile 20 forming the inner surface of the frame 3. The side surface 6 is gradually narrowed, so that the width of the profile 20 is reduced at its bottom, that is, at the outer peripheral surface of the frame 3. The sealing adhesive 7, which has permanent elasticity, rests on the side surfaces of the profile 20 on the one hand and on the glass plates 1 and 2 on the other hand, and serves as a bond suitable for the function of this part. A recessed space formed between the edges of the glass plates 1 and 2 and the outside of the mold member 20 is also filled with a sealing material 8 having permanent elasticity. All shapes 20 used in the production of frames 3 of this type for insulating glass plates
What they have in common is that they are formed as hollow members. The hollow parts 9 of these profiles 20 accommodate the moisture absorption material 19, which
The interior space 10 between the glass plates 1, 2 is accessed through a slot 5 or an optional row of holes in the glass panes 1, 2. This moisture absorbent material 19 is sold in the form of small balls from related industries. The diameter of these globules is approximately 1-2 mm.

In order to manufacture the frame 3, which is formed exclusively by bending sections of the profile 20, a single profile 20 having a length corresponding to the circumference of the frame to be made is first used. Here, a cut 11 is made in the wall surface 4 where the slit 5 or hole row is located in the bent portion of the profile 20 (see FIG. 2). This cut 11 is oriented at right angles to the longitudinal direction of the profile, and the depth t of the cut 11 corresponds at least to the wall thickness s of this wall 4. Portions A and B formed by such a cut 11 are then bent to each other (arrow 12),
This creates one corner (see Figure 3). At this corner, the outer surface of the frame undergoes considerable deformation, but what is important is that the side surface 13 of the profile does not curve outward, but remains mostly upward, as has been proven through many experiments. It is. The corner and its side surface 1 are shaped so as to ensure that the outward curvature of the side surface 13 of this corner is prevented during the bending process.
3 is guided by a jig.

In a further development of the invention, a plurality of parallel incisions 11', preferably three incisions 11', are provided in the area intended as the corner (see FIGS. 4 and 6). A connecting portion 14 remains between each cut 11'. The width b of each cut 11' corresponds approximately to the width c of the remaining connecting portion 14. The depth of cut in this case is selected to be slightly larger than the wall thickness s of the profile 20.

At the end of the next bending in the direction of arrow 12, the edges 15 and 16 on both sides of these notches 11' collide with each other (see FIG. 7), and the connecting portion 1
4 is sandwiched between them, so that an approximately uniform and even flow of the material in the corner sides 13 is achieved. FIG. 7 shows the corner obtained by deforming the notch 11'. Approximately 6 for a profile width of approximately 12 mm
The full width of the cut D (see Fig. 6) was mm. These cuts 11' are so narrow that the profile 20 can be filled with moisture-absorbing material 19 either before machining or after the cuts 11' have been made. Then, the end face of the mold material 20 is closed to prevent this small spherical material from flowing out. By providing the cut 11' as described above, the moisture absorbent material 1
9 is prevented from spilling out. The position of the notch 11' is set so that both ends 17 and 18 of the profile 20 are located in a straight line portion of the frame after manufacture (see FIG. 8). The ends 17, 18 can simply be joined by suitable couplings or suitable intermediate pieces. As a result, the abutting portions of the shapes 20 can be located at positions where they can be easily joined in terms of manufacturing technology in the production of insulating glass plates. Therefore, the drawbacks of conventional insulating glass plates are completely eliminated by the present invention.

Although the present invention has been described above in detail with respect to an example in which the mold material 20 having one cross-sectional shape is used, it must be made clear that the present invention is not limited to the use of mold materials having such a cross-sectional shape. The present invention is commonly used in the production of this type of spacing frame,
It is also possible to apply the present invention to mold members having other shapes having hollow portions for accommodating the moisture absorbent material 19. A profile of this type is shown in FIGS. 9-12. 9th
The figure shows a shape material prepared with a cut similar to the cut 11' in the above embodiment, and the 10th figure shows a state in which this shape material is bent in the same manner as in the above embodiment. In this example, the shape material has a simple rectangular cross section. have This profile is formed into a closed rectangular cross-section by appropriately winding a flat strip. FIG. 11 shows a shape before bending having a plurality of rows of holes 21 (see FIG. 14) arranged in rows in the longitudinal direction, and also has cuts similar to the cuts 11' in the above embodiment. It is shown installed and ready.
FIG. 12 shows the state after bending.

This type of profile is usually made of light alloy,
The present invention is not limited to such light metal shapes, but good results can also be obtained with, for example, drawn or rolled steel shapes. In all the cases mentioned above, there is a precise and perfect inner abutment edge, and the sides are almost flat, which is of great importance for these frame profiles, as already mentioned above. Depends on the reason. Each outer circumferential surface is deformed considerably at the corners, but this does not adversely affect the quality of the frame, on the contrary, this deformation causes the sealing material to be applied to the outer corner of the glass plate. This leaves a relatively large space to be filled, and a large amount of sealant is packed in a potentially dangerous area.
