Description

windows with ventilation holes

technical field

The present invention relates to a window comprising a sash/frame structure supporting a pane in which a single vent is employed between the outside and inside of said window. Airflow transfer between.

Background technique

Co-pending patent application WO 99/51832 describes a roof window in which a sash supporting the pane is openably mounted in a window frame. A longitudinal ventilation slot is formed in the upper part of the sash part and can be closed by means of a flap hinged to the inner side of the part. In the closed state of the window, the room in which the window is installed can be ventilated by opening the flap, whereby through the ventilation slit in the part between the inside and the outside of the window pane and between it An air flow passage is formed through a slit between the sash and the window frame in the continuation of the sash.

Patent document DE 36 22 652 describes a front window in which the window pane in a sash is openably mounted in a window frame. In the upper sash part, two through-stroke ventilation channels are formed, each of which has an integral ventilator with a sensor-controlled switch and automatic regulation for effective ventilation of the room device, windows are installed in said room. Moreover, the air duct has a vertically displaceable damper to allow manual adjustment of the strength of the ventilation.

However, in some cases when proper ventilation is obtained by opening specific windows or possibly other windows in a building, it is only necessary to ensure that there is a predetermined permanent window between the inside and outside of a closed window. Minimum airflow path. In particular, modern buildings are so airtight that such forced minimum ventilation is necessary due to the indoor climate. The exact flow required depends on local factors, but in all cases it should not be greater than required as this would result in unnecessary heat loss. However, the prior art solutions do not allow for a permanent and adequate exact setting of such a suitable small air flow channel when such a suitable small air flow channel is required in certain situations, because according to existing needs these solutions It is provided for the opening and closing of the proper air passage. Furthermore, prior art solutions are often unnecessarily complex and therefore expensive to manufacture.

Contents of the invention

It is an object of the present invention to provide a structurally simple window to provide a predetermined minimum flow path between the inside and outside of said window.

In view of this, according to the invention, the window is characterized in that an annular valve casing is inserted in the vent opening, the flow area of the valve casing is partially covered by the seat surface, and a closing body is placed in the The valve housing is connected so that the closing body is pivotable between an open position in which the closing body overlaps the seating surface and a closed position in which the closing body overlaps the seating surface and in which In the closed state of , the closure body and the seat surface together cover substantially the entire flow area of the valve housing.

Such valve housings can be made suitably small so that a minimum air flow can be provided at appropriate intervals. Furthermore, the pivotable connection of the closing body provides a suitably long flow between the open and closed states of the valve to allow accurate setting of the air flow. Furthermore, the pivotable connection of the closing body ensures minimum friction at the opening and closing movements. For example, the valve housing combined with the closing body can be produced in a simple manner when the two parts are injection-moulded. Furthermore, installing the valve housing in the sash or window frame is easy when simply drilling a through hole and thereby, for example, pressing or gluing the valve housing into the hole. Another advantage is that the expansion of the valve housing is quite limited, thus causing only minimal changes on the surface of the window. Furthermore, this makes the valve almost invisible to the user, so the user does not have to change the permanent preset of the air flow.

In a preferred embodiment, preferably, the valve casing is in the shape of an annular cylindrical tube, and the closing body is pivotable around an axis coaxial with the cylindrical tube. A tubular valve casing engaged with the axial connection of the closure body maximizes the flow area of the valve casing and the utilization of the long flow of the closure body, that is, within a rotation range of 180°, This makes precise settings possible. Furthermore, the cylindrical tube is also easy to install so that it fits tightly in the hole in the sash/frame structure.

In an embodiment, which is preferred in terms of manufacture, said seat supports a pivot bearing for said closing body.

In a preferred embodiment, the shape of the seat surface and the closing body is a semicircular disk. This makes it possible to have a maximum air flow with respect to the size of the valve housing; in other words, the size of the valve housing can be minimized and the closure body in the open state and in the closed position The maximum possible flow can be obtained between them, which then allows for a more precise setting.

The valve housing may have an end stop for the closure body so that further pivoting of the closure body is prevented when it reaches its fully open or fully closed position. Therefore, a specific pivoting direction can be defined for opening and closing of the valve and also for clearly indicating the fully open and fully closed states. This facilitates the operation of the valve.

In a preferred embodiment, the closure body and the valve housing each have locking means for engaging with each other at several different fixed states of the closure body relative to the valve housing. This facilitates the presetting of specific air volumes when defining different step settings for the closing body. These settings may be numbered, then it is sufficient to provide the window fitter with the exact number of said settings to ensure a suitable preset. Furthermore, the locking means can be formed together with a firm engagement to prevent subsequent unintentional placement of the closing body in the fully installed state of the window.

According to manufacture, in a preferred embodiment, the locking means are respectively formed as a protrusion on said closing body and several corresponding recesses in said seating surface.

Preferably, the closing body can be sealed in one arrangement relative to the valve housing, for example by means of an adhesive arranged between the closing body and the seating surface of the valve housing. This ensures in a more efficient manner that the presetting of the closing body cannot subsequently be changed.

In a preferred embodiment, the sash/window frame structure is composed of a sash and a window frame, the sash supports the window glass and is openably connected to the window frame, therefore, the Said window sash has an upper part, a handle extends parallel to it for the operation of the locking mechanism of said window, and said valve housing is arranged at the upper part behind said handle, so, in said window In the closed state of the window, the handle at least partially covers the valve housing towards the inner side of the window. The valve housing is thus partly concealed, which has the advantage of being aesthetically pleasing, and also minimizes the risk of unintentional rear setting of the closing body.

In another preferred embodiment, an elongated ventilation slot is formed in the upper part of the sash for air flow transfer between the outside and the inside of the window, by means of a ventilation damper The ventilation slit can be closed by operation of the handle, the ventilation flap is hinged on the upper part, and the valve housing is inserted into the ventilation flap. While it is possible to pre-set a specific minimum air flow path, which will always be present in the building structure in question, this allows to manually set the appropriate ventilation in the case of the application.

Detailed ways

FIG. 1 shows an internal view of a window 1 comprising a sash 2 supporting a pane 3 and pivotally suspended about an axis 4 in a frame 5 . On the inside of the window, along the upper part 6 of the sash 2 and at a distance therefrom, a handle 7 is provided for opening and closing said window 1, that is, for opening and closing relative to said sash 2 of window frame 5. On the right side of the upper part 6 of the sash, there is an annular valve 8 half covered by the handle 7, as shown in the sectional view. The structure of the sash 2 and the window frame 5 can also be fixed to each other or integrally formed so that the window cannot be opened. Furthermore, in the embodiment shown in Fig. 1, said valve 8 could also be located on the window frame 5 instead of on the sash 2, as shown.

FIG. 2 shows a sectional view through the valve 8 installed in the window sash 2 along the section line II-II in the window frame 5 of FIG. 1 . The valve 8 is shown in detail in FIGS. 3 to 6 and has a tubular valve housing 9 which is inserted into a corresponding annular hole 10 in the upper part 6 of the window 2 . The tilting of the handle 7 releases the locking mechanism 11 between the sash 2 and the window frame 5, so that the window 1 is opened by further pulling the handle 7, and the sash 2 is opened relative to the The window frame 5 is tilted about an axis 4 . Said locking mechanism 11 may be of a conventional, known type.

The annular flow area of the valve housing is partially covered by a semicircular seat surface 12 on the inner side of the window sash 2, the seat surface 12 supports a bearing bush 13, and the seat surface 12 is arranged axially on the In said valve casing 9, and as shown in Fig. 3 and Fig. 4, there is also a semicircular closing body 14, which is pivotably connected in the axial direction by a pivot pin 15 in the casing 9 . The pivot pin 15 is split along its axis of rotation and has a wedge-shaped barb 16 at its free end, which is located on each side of the slit, so that when the valve When the casing 9 and the closing body 14 are assembled together, the pivot pin 15 can be pressed into the bearing shell 13 around the slit and then self-locked in the bearing shell by means of the barb 16 by expansion. , the barb 16 abuts against the end face 17 of the bearing bush 13 . Along its straight surface, the closing body 14 has projections 18 for gripping the surface during operation of the valve; for example, at diametrically opposite areas of the projections 18 in the valve along Along their lower and upper sides there may be a gripper which can be operated by the thumb and forefinger respectively.

As shown in Figure 3, in the closed state of the valve 8, at the position where its lower surface is introduced into the valve casing 9, the annular edge of the closing body 14 abuts against a protruding portion 19, which protrudes 19 extends along the curved side of a semicircular hole 20 in the valve housing 9, which hole 20 is located under the closing body 14 in the closed state of the valve and which is located in the open state of the valve , the hole 20 forms a through hole for the valve, as shown in FIGS. 5 and 6 . Along the outer edge of the valve housing 9 there is a circumferential projection 21 which abuts against the inside of the upper part 6 of the sash 2 at the installation position of the valve in the sash 2 . Furthermore, on the outer side of the valve housing 9 there are several ribs 22 extending in the axial direction and arranged in the circumferential direction of the valve housing. When the valve housing 9 is installed in the hole 10, these ribs 22 fix the valve 8 relative to the upper part 6, so that, when in operation, the valve cannot rest in the hole. 10 spins.

In order to lock the closing body 14 at different positions relative to the valve housing 9, the rear portion of the closing body 14, that is, the side facing the valve housing 9, has a protruding portion 23, which protrudes 23 can be engaged with several depressions 24 formed on the outside of the seat surface 12, that is, on the side facing away from the valve housing 9, the depressions 24 being set in the circumferential direction of the valve housing. As shown in FIG. 3, the valve 8 shown has three recesses 24 in the seat surface 12 so that the closing body 14 can be locked in three different partially open states, shown in FIG. 5 as in an intermediate state. Moreover, as shown in FIG. 4 , in the fully closed state of the valve, the closing body 14 can be locked, and the protrusion 23 on the closing body 14 can be snapped onto the straight side surface of the seat surface 12 25 on. Similarly, as shown in FIG. 6 , in the fully open state of the valve 8 , the protruding portion 23 can snap onto the straight-edged surface 25 . Thus, four different fixed flow areas for the valve 8 are defined, however, the valve can also be formed with more or fewer recesses than the three shown, whereby it is possible to define More different flow areas. When the closing body 14 is mounted in the valve housing 9 in such a way that it can pivot tightly so that it can be held in a specific position, it is also The valve 8 may be formed without the protruding portion 23 and the recess 24 . By placing a small dot of liquid adhesive between the seat surface 12 and the closure body 14, the closure body 14 can also be held in a specific pre-set position when the presetting is done. The closure body 14 can also be sealed in other ways relative to the valve housing 9 , for example by means of a thread through a hole in both the closure body 14 and the valve housing 9 .

Moreover, said closing body 14 has an end stop in the form of a pin 26 which is placed at the straight side surface of said closing body and which protrudes into said valve housing 9, so that, as When the valve shown in Fig. 3 and Fig. 4 is in a fully closed state and as shown in Fig. 6 when the valve is in a fully open state, the pin 26 can abut against the straight edge surface of the seat surface 12 25 , which thus prevent further rotation of the closing body 14 when these positions are respectively reached. Preferably, the valve housing 9 and the closing body 14 can be injection molded products.

As shown in Figure 2, air flow can be formed from the outside of the window to the inside of the window through the valve 8 through a passage 28 between the sash 2 and the window frame 5 and through a dust filter 27. . Thus, in one of its open states, the presetting of the valve 8 ensures a permanent supply of a minimum amount of fresh air into a room in which the window 1 is installed. Obviously, further valves 8 can be installed in the window 1 and, like the side parts, the valves can be arranged as desired in the sash/frame structure of the window, i.e. in the upper and the lower two. Instead of installing the valve 8 directly in the several windows 2, the valve 8 can also be installed in an openable ventilation flap which is openable in the upper part 6 of the window 2 and close a ventilation slit. By opening the ventilation damper, it is possible to ensure proper ventilation in the room, and when the ventilation damper is in a closed state, a minimum amount of fresh air can still be ensured to enter the room.

It is worth noting that instead of installing said valve 8 in the position shown in FIG. The closing body is difficult to access, and when its unintentional operation is prevented after the installation of the window, the valve 8 can also be installed in an opposing manner, so that the protrusion 18 and, if possible, the closing The body 14 faces outwards from the outer side of the upper part 6 of said sash 2 . It is also possible to replace the protrusions 18 on the closure body 14 with one or more small depressions at the surface of the closure body 14, so that a specific tool can be used with these for the closure body 14. Engages in the recess of the operation. This can also prevent unintentional actuation of the closing body. Moreover, it is worth noting that, thanks to the operation of said protrusion 18, in all positions of the closing body 14 relative to said valve housing 9, when said protrusion 18 is accessible along the entire diameter of said valve housing When approached, said closing body 14 is pivotable on the outer surface of said seat 12 .
