Description

I) OPPEL SLIDING WINDOW The present invention relates to a double sliding window, Each glass wall consists of several panes, with the panes of each glass wall in the closed position overlap a little, and with the discs next to are arranged slidably in the upper and lower guides in the Swell of the window frame, of which the mullions have receiving grooves and the Panes without a frame are arranged in the window frame. A similar window is e.g.

known under the name Pierson Fensterrahmen and is made by Ramenfabriek Leerdam put on the market.

The construction of such windows is in general, quite expensive, because the seal is achieved by additional pressure rollers that are used to press on parts of the overlapping window and therefore for sealing these slit-shaped Openings must be made. In addition, only one slice from each can be played at a time The glass wall can be pushed up as the pressure rolls and the hand buttons interfere with each other With these pressure rollers, the windows are still quite expensive.

The aim of the present invention is to provide a double sliding window to create the above-mentioned embodiment, which is produced in a simple and inexpensive manner without affecting the seal.

This goal is achieved according to the invention in that the cavity between the panes is in communication with the outside air in such a way that a wind force acting on the window into a static air pressure in the cavity is implemented and that between the guides of the inner disks partially none Separation is present so that in the closed position the overlapping Parts of the inner panes can be pressed against each other.

With such a construction, when the wind is weak, the gap becomes remain open between the overlapping parts of the inner panes, so that this air flow is throttled sufficiently and does not have a disruptive effect. . With stronger Wind presses the overlapping parts against each other and creates a seal achieved. As a result, additional measures can be taken to press the overlapping pane parts are left behind, making the window cheaper will.

In order to avoid that about the connections of the cavity with water penetrating from the outside air collects and eventually seeps inwards would, the lower threshold is designed in a slanted shape and with discharge openings ar the water that has entered.

Further details of the invention emerge from the following Description of the embodiment shown in the attached drawings. In the drawing is Figure 1 is a plan view of a double sliding window according to the invention, Figure 2 shows a cross section along line II-II of Figure 1, Figure 3 shows a cross section along line 111-111 of FIG. 1, and FIG. 4 shows a graphical representation Representation showing the relationship between wind pressure and air passage.

The window shown in Figures 1-3 consists of two glass walls; each glass wall is made up of two panes 1, 2 respectively. 3, 4 formed. Although the following Description refers to a window and each glass wall consists of two panes, The invention can also be applied to windows, each of which consists of three or more glass walls even consists of several disks, can be applied.

Each disc 1, 2, 3 and 4 can be moved in lower guides 5, 6, 7, 8, the panes 1, 2 of the hussenglaswand having a common upper Guide 9 and the panes 3, 4 of the inner glass wall form a common upper guide 10 have. The length of the inner pane 4 of the inner glass wall is somewhat smaller than the height of the outer pane 3 of the inner glass wall, so that the upper edges of this Washers against sealing strips 11, 12 can rest.

Receiving grooves 13 and 14 are arranged in the standing cattle; these grooves 13 for the panes of the outer glass wall have a normal, rectangular one Cross-section, so that thereby a certain connection between the cavity and the outside air is created. The receiving grooves 14 for the panes of the inner glass wall have a rectangular trapezoidal shape in cross-section so that when closed Window the side winds of the discs and the receiving grooves 14 in such Relation to each other that a seal comes about.

The separation 15 between the lower guides 7 and 8 of the inner glass wall does not extend over the entire underside of the window, so that the inner pane 3 the inner glass wall can be pressed against the pane 4 in the closed Position of the window.

The lower sill of the window has a sloping shape, such as shown in Figures 2 and 3, and behind the guides of the outer wall is a groove provided in which any water that may have penetrated can collect. The groove 16 is in contact with the outside air through passage openings 17 so that the water that has accumulated in the grooves can drain away.

Between the upper guides 9 and 10 is a removable profile 18 arranged. Since the upper guides 9 and 10 have a sufficient depth and by removing the profile 1r, the window panes can be easily arranged and be removed.

When the window is inserted, it is evident that in closed Position of a wind force acting on the window through the passage openings 17 acts on the cavity, as well as on the parts between the overlapping parts of the Discs 1 and 2 left open gaps, and on the through the receiving grooves 13 formed passages with the side edges of space 1 and 2. This creates some kind of static pressure in the cavity, which when acting on the window Wind strength is strong enough, the overlapping parts of the panes 3 and 4 against presses each other, so that an almost complete seal of the inner glass wall is achieved will.

Example by the Institute TN0 for fiber and building structures A window was checked according to the following specifications and the results were checked were set out in the report B-69-254./02.6.0024.

The test window consisted of a wooden frame with an outside width of 191 cm and an external height of 98 cm, with two cloister joints in which two Pair of discs were arranged, which were horizontally displaceable. The joints in the lower threshold were with plastic elements in the form of a guide profile Mistake. In the upper threshold there was an elastic on the inside of the inner panes Plastic pull profile arranged. The outer panes were loosely in the joints.

The inner panes of the posts were against the sloping one Cloister joint. Here, too, the outer panes stood loosely in the straight joint.

In the lower threshold, the outer panes were in a total of four Holes / 8 mm arranged.

These details are characterized in that the cavity between the pair of panes was intentionally in contact with the outside air. at Wind thereby became the pressure in the cavity almost the wind pressure against the window equal.

The outside of the test window was against an almost air-tight and a watertight steel cabinet. There were sprays in the cupboard, through which an almost closed layer of water (approx. 120 liters per hour) over the Window could be sprayed. The air pressure in the closet could be controlled by a fan increase.

The following experiments were carried out in succession: The test window was wetted for 15 minutes without excess pressure with about 120 liters of water per hour, The static air pressure was then gradually increased at the bottom of the range. Everyone Pressure was held for 10 minutes and attention was paid through the window penetrating water.

During the rain test, the pressure in the cavity was measured. the Results of the rain test are recorded in Table B. From this table goes showed that the window did not let any water through at an excess pressure of 50 kgf / m2.

Table B Results of the rain test overpressure in kgf / m² Number of leaks Place leak water minutes amount In the In the cabinet cavity 0 0 15 no leak through the lower side of the outer panes and through the overlap of the panes in the middle, water penetrates the plastic profiles and this water flows through the drainage holes to the outside 2 5 4 10 no leak (as with 0 kgf / m) 10 9.5 10 none A few small leaks penetrate the opening between the two outer panes Drop in 20 19 10 no leak, as at 10 kgf / m2 30 28.5 10 no leak, as at 10 krrf / mR 40 38 10 no leak, as with 10 kg a2 50 47.5 10 no leak, as with 10 kgI / m2 In the cavity, the lower threshold got a little wet. With different air overpressures In the cabinet, a measuring disk was used to determine the amount of air supplied had to be so that the relevant overpressure could be maintained These The amount of air was rated as having passed through the window and the rain cabinet Air.

Thereupon the window seams were finished exactly and became the Air permeability of the rain tank and the window frame measured.

The difference between the first and second amounts of air became evaluated as the amount of air allowed through the window. Table B shows the Air permeability of the sample window By at an excess pressure of 14 kgf / m2 the Inner panes were pressed against each other, the air permeability of the window became considerably less.

Table B Air permeability of a double sliding window, sample number 2-1371; Dimensions of the window joints: post length 90 cm, threshold length 183 cm (Joint length 636 cm) Excess pressure in kgf / m² m³ air per hour 1 10.5 2 17.5 10 120 14 175 the inner panes are pressed against each other 14 53 50 230 The in Figure The graph shown in FIG. 4 shows the relationship between the wind pressure P and the air passage Q with a double sliding window, Ifilt a length of 183 cm and a height of 90 cm.

With the help of the table and the graphic representation came.

calculated that the window at 1 kgf / m2 overpressure 1.6 m3 Air per meter of window joint.
