Ventilation device

 

(57) Abstract:

The invention relates to a ventilation device for Windows or doors. The device is located with the possibility of movement between the sash frame and single frame sealing strips, which are placed on all sides of the frame between the bars of the frames and independently from each other can use the actuator to vdvinut'sā and to move in the plane of the window or frame and choose to open the air gap between the bars of the frames. To perform such ventilation devices more convenient to use provided that each actuator of each of the sealing plates or rods through the valve is connected with all other actuators with actuator that latches with a common actuator valves are few, however, at least three position switch, and that at least one actuator relative to the path of movement of the valve opens or closes the air gap in front of the other actuators. The technical result is a simplification of the control device and installation. 6 C.p. f-crystals, 17 ill.

The invention relates to ventiljats the 46857 disclosed ventilation device, in which the sealing strips are located on all four bars separate the window frame. Manual levers allow you to push and pull the sealing strips independently of the other seals. Thereby, it is possible to open or close the air gap between the frame bars. Rotary opening casement Windows can be made that all sealing strips are transferred to the open position.

However, a disadvantage is that to control ventilation device required manual control levers on each timber frame. In contrast to that adopted in the present management of such a ventilation device provides only one control manual lever. At the same time very difficult is the installation of such a ventilation device, since every timber frame it is necessary to provide the actuator and the control hand lever. To rotate the shutters are necessary to give effect to all control hand levers that at high frame creates problems, because the upper manual control levers are not available.

Therefore, the basis of the invention lies in the challenge to create a ventilation device that is uchitelnic signs of paragraph 1 of the claims.

The ventilation device can be managed by the same Manager manual lever, which can be located with good access request on the vertical or horizontal timber sash or frame. Ventilation device with interconnected with drive actuators to perform so that the slats are moved sequentially, i.e., with a shift in time. Due to this not only reduced to the minimum necessary force control, but it is also possible and easy individual adjustment of the ventilation device. Due to this reduced to a minimum also significant costs associated with deploying manual control levers.

Modification of the venting device provides that each actuator has a sliding guide, which is installed with the possibility of relative movement of the rocker stone or pin. This rocker guide you can easily and economically produced and it provides the ability to effectively move the slats.

To ensure installation of the various provisions ventilation ventilation device asselineau shift valves. The sequence of switching moving and stopping is achieved by the fact that the scenes later opening the switching devices have the travel or the land of the dead stroke, during which occurs the Executive of the movement of the corresponding plate.

From DE-AS 1242121 known Central locking connected to each other via the angular gear locking and closing straps covering strips which have a semicircular cross-section. In addition, known from this publication, the Central lock provides on each timber frame dramatically, with each corner region is provided by deflecting device consisting of a conical wheels. Straps lead to the closed position by rotation, and in the open position of the Central locking flat surface semicircular cross-section is in the plane of a fold frame, and in the locking position semicircular strap is rotated 90othat covers about a quarter of a circle located between the sash and frame air gap and enters or retracts into the groove located opposite the groove to accommodate the strap.

The disadvantage of this device is that you can't pcen angular transmission in the form of conical wheels however, they do not allow different movements closing of the slats and are very expensive to manufacture.

To resolve the known disadvantages of such Central locking system the invention provides, along with evidence under paragraph 1 of the claims in addition that if the strips are approximately semicircular cross-section and for pull-out and lowering fixed to rotate a near flat cut, the scenes are located in the side surface of the semicircular outside slats.

To prevent the ingress of water or dirt in the host bar groove is additionally provided that the strap is provided with a band-shaped seal, which is attached to one longitudinal side to the outer edge of the groove, and the other longitudinal side is fixed on the remote from her longitudinal edge of the flat section of the strap. Due to this not only prevents the ingress of dirt or moisture, but also folding in position closing strap ensures a reliable seal the entire area of a fold due to sticking, respectively, perpendicular to seam seal.

In Fig. 1 shows a ventilation device 1, consisting of separate fixed frame 2 and leaf 3 with glass. The sash 3 and separate the frame 2 can be rotated relative to each other around the axis 4 by means not shown here, the hinge device. In addition, the shutter 3 can be fixed relative to the separate frame 2 with sealing strips 5, 6, 7, 8, called in later strips, if the sash 3 and separate the frame 2 adjacent to each other in one plane.

In the closed position C is not shown here, the device with the valve rod 5, 6, 7, 8 are transferred to the position of the closing. Therefore, the rod 5, 6, 7, 8 are separate from the groove of the frame 2 until the opposite groove of the sash 3. Fold 3 use the strips 5, 6, 7, 8 blocked relatively separate frame 2 and can't be opened. At the same time the rod 5, 6, 7, 8 condense separate frame 2 and door 3 with respect to each other, so there is no exchange of air with the external air.

In the second switching position according to Fig. 2 strips 5, 6 is drawn back into the groove of the separate frame 2. However, the strips 7, 8 are in engagement with the opposite groove of the sash 3, so that the sash 3 cannot be opened. Through nagustuhan. Is the ventilation of the premises without the shutter opening 3 of the ventilation device 1. If this is not removed, the sash lock 3.

In order to be able, in particular, to wash the glass, as well as for ventilation or create escape routes, ventilation device you can finally translate to the open position shown in Fig. 3. This strips 7, 8 are removed from the opposite groove of the sash 3. Now the shutter 3 can be rotated around the axis 4.

In the shown example, the execution of the strap 5, 6, 7, 8 must rely on shelves 12, 12' and 12" frame.

In Fig. 4 shows the lower corner region of the ventilation device 1 in an isometric projection. Separate frame 2 through the hinge device 10 is connected with the sash 3. Strap 5 is placed in the groove 11 of the lower horizontal beam 12 of the frame. In the shown position of the switch rod 5 it is in the opposite groove 13 of the sash 3. In the groove 11 is the device 14 with valves, which is sent with the possibility of longitudinal displacement by means of holders 15 of the valve 16. Through the holder 15 and the valve 16 is held fastening element 17, for example, a screw. For this purpose, the valve 16 has an elongated hole 18.

Plinii switching rod 5 is attached to the bottom 21 of the groove. The dimensions of the rod 5 and the groove 11 are coordinated so that the strap in the open or venting position of the ventilation device 1 leaves the air gap 9 between the separate frame 2 and door 3. The upper limit of 5 is almost completely coincides with the surface 22 of the rebate separate frame 2.

In Fig. 5 shows a corner region of the ventilation device, and the shutter 3 is not shown, and a separate frame 2 is cut in the plane of the groove 11.

Length of the strips 5, 6, 7, 8 almost corresponds to the length of the surface of a fold of the corresponding beam separate frame 2, so that the rod 5, 6, 7, 8 acting on the entire length of the field seam. Valves 16, 16' in the corner area separate frame 2 are connected by the angular transmission 25 is able to transmit motion. Valves 26, 27 angular gear 25 is connected through a not shown here, the connecting device with the valves 16, 16'. Angular gear unit 25 is equipped with actuators 28, 29, which serve to force the conversion performed by the valves 16, 16' or 26, 27 movement of displacement in movement of the lower and pull-out slats 5, 6, 7, 8.

For this purpose, the actuators 28, 29 are one of the wings 30, 31 on the plate 32, 33, which is connected to the valve 16, 16' or 26, 27. In d odigna mounted on a separate frame 2, either a single block with an angular transmission 25 or, respectively, additionally between the angular transmission. The plunger 35 includes a rocker-stone or pin 37 in the connecting rod 30, 31, so that the plunger 35 for longitudinal displacement of the plates 32, 33 under the action scenes 30, 31 slides along the formed holder 34 of the guide.

The rod 5 and 8 shown in Fig. 5 in the open position. Rocker stone or pin 37 is in the first position And the switch is in the open position at the end 38, respectively, 39 (Fig. 7, 8) of the wings 30, 31. In the last (end) position C switch - position opening by turning the rocker stone 37 comes to the other end 40, ACC. 41 wings 30, 31. When the plunger 35 is shown in Fig. 6 position. The rod 5, 8, as well as not shown here strap 6, 7 extended from the groove 11 and is pushed in the opposite groove 13. When the rod 5, 6, 7, 8 are pulled out of the groove 11 only vertically. Longitudinal movement of the strips 5, 6, 7, 8 does not occur.

Backstage 30, 31 plates 32, 33 are made different as shown in the image on the wings 30, 31 in an enlarged scale in Fig. 7 and 8. The actuator 28 (Fig. 8) on the lower horizontal beam 12 of the frame has a first segment 45, passing the plans moving scenes 30 - together with the plate 32 is first moved. Therefore, the valve 16 will act or is on the site of the dead stroke 46, so that no movement of the actuator 28. To cut 45 adjacent segment 47, which runs obliquely to the direction 36 offset. On this segment 47 of the plunger 35 in the guide holder 34 extends upward from the groove 11. In this case, valve 16, respectively, the plate 32 will act 48. Finally, the rocker stone 37 hits for a segment 49, which runs parallel to the segment 45. The valve 16 to the end of the 40 scenes 30 performs advanced course 50. On the segment 49 of the plunger 35 is not moved.

The actuator 29, which is located on the vertical timber frame 51 has a connecting rod 31. The connecting rod 31 has a first segment 52, which runs parallel to the direction 36 of the shift valve 16'. The plate 33 to overcome the segment 52 will act 53. This move 53 is dead stroke and has approximately the amount equal to the sum of the stroke, respectively, of the dead stroke 46 and turn 48 of the valve 16. The route 52 should segment 54, which respectively segment 47 the scenes of 30 passes obliquely to the direction 36 offset. Plate 33 on this segment performs the move 55. The last section 56 backstage 31 aisle is even such run of the wings 30, 31, for example, according to the position And the switch relative to the path of movement of the valve 16', 16", first moves only plank 5 (respectively, 5 and 6) the lower horizontal bar 12 of the frame. This rocker stone 37 of the actuator 29, which is located on the vertical beams 51 of the frame, is dead stroke 56 without moving the strap 8 on segment 52. Therefore, in the second position of the switch only strap 5 from position A switch, in which the strap 5 is pushed into the groove 11, extends in the opposite groove 13, relative to the path of movement of the valve 16, 16' actuator 28 opens the air gap 9 in front of the other actuator 29. Finally, at the next switching device 14 with the valve in the third position C moves only strap 8 (respectively, 8 and 9) and comes into engagement with the opposite groove 13. The distance between positions A and B of the switch relative to the path of movement of the valve 16, 16' corresponds to the distance from B to C.

This embodiment leads to the fact that between the positions A and B, respectively, B and C of the switch moves only the desired number of strips 5, 6, 7, 8. When the desired number of strips 5, 6, 7, 8, which should peremislov 28, 29. This means for actuating required significantly less effort, because at the same time should not be moved all the strips 5, 6, 7, 8. Thus, the valves 16, 16', respectively, 26, 27 can be made thinner than would otherwise be necessary while simultaneously move all of the slats 5, 6, 7, 8, arise because less effort. Of course, nearby laths, for example, the rod 5, 8 can be equipped with the same scenes. In addition, it may be provided that in the second position B switch only one or three of the strips 5, 6, 7, 8 slide in closed position.

Backstage 30, 31 are made with appropriate symmetry about a point. Thus, the rocker stones 37 pass through the wings 30, 31 in a sense the movements: the end 38 backstage 31 corresponds to the late 40 30 scenes; the segment 45 backstage 30 has the same length as the segment 56 backstage 31; the segment 47 correspond in size to the segment 54, as well as a line 49 corresponds to the segment 52. Due to this, it is also possible economical manufacture of the plates 32, 33 because they have the same form scenes. Only the arrangement of the plates 32, 33 relative to the valves 16, 16', respectively, 26, 27 is different.

sustained fashion mechanisms 28, 29, so you can choose to have the desired characteristics for the switch.

Essential for the reliability of such a ventilation device is that it prevents a reverse bias strips 5, 6, 7, 8. Backstage 30, 31 are in positions A, B, and C switching perpendicular to the direction of displacement of the strips 5, 6, 7, 8 segments 45, 47, 52, 56, so that a reverse bias strips 5, 6, 7, 8, for example, introduced into the air gap 9 hacking tool not only difficult, but also does not move the valves 16, 16'. This smolokurovka prevents that by lowering one of the strap through the fixture valves are moved at the same time all other trims.

For the operation of the ventilation device 1 is expedient that between separate frame 2 and door 3 remains an open air gap 9 is in the ventilation position (Fig. 2), and that they are constantly at such a distance from each other that a separate seal frames 2 and leaf 3 is only through the slats 5, 6, 7, 8. Therefore, provided by the profiling beams of the frame in accordance with Fig. 9 and 10. Profile section according to Fig. 9 refers to the window that is made of wood or sostavlennyi in the context of the lower horizontal bar 12 of the frame is different from the known profile of the position and shape of the groove 11. Firstly, opposite the groove 11 is located opposite the groove 13 in the sash 3. The surface 22 of the rebate separate frame 2 and a fold 60 fold spaced from each other. Overlap 61, which partially overlaps the end surface 61 a separate frame 2, are also separated from this end surface 61 of the air gap 9. Simultaneously, the groove 11 is located at a distance from the floor 61, so that it is near the longitudinal middle line of the cross-section of the beam.

Not pictured here strap 5 in the closed position (Fig. 2) adjacent its convex performed by the seal 20 to the concave executed the bottom 21 of the opposite groove 13 and locks the air gap 9. In the form shown in Fig. 2 position ventilation strap 5 is pushed into the groove 11, and in this area is released the air gap 9. As the leaf 3 also hold straps 7, 8 relative to the separate frame 2, the air gap 9 retains its dimensions.

In the field 62 facing the outside surface 63 of a fold is made sloping to drain possible penetration of water from the area of the rod 5 to the outside. Rain Planck 64 forms the outer part.

The groove 11 through not pictured here is a hole in the bottom of the groove is connected with the external air is the differences from the run shown in Fig. 9 wooden profile is that along with the groove 11, respectively, opposite the groove 13, is provided by the camera 70, respectively, 71. This camera 70, 71 serves to accommodate other parts of the device that is not shown here. An example of such parts of the device can be articulated part and/or the drivers for the device with latches.

The camera 70 is located so that the armature 72 of the lower horizontal beam 12 of the frame does not pass between the groove 11 and the camera 70. Otherwise, the valve could be a hindrance to the drive connection located in this area of the unit with a bolt.

Significant is also the fact that the armature 73 of the leaf 3 is located so that the opposite groove 13 to almost fold 60 fold is surrounded by a valve 73. In the shown embodiment, the armature 73 is made so that it is approximately U-shaped covers opposite the groove 13. Due to this, prevents the ingress of, for example, by hacking into this area on top of those in the closed position of the strap 5, 6, 7, 8.

However, it is also essential that the groove 11, at least on the outer side of the air handling unit, built vertical shoulder 74 of the valve.72. T is carried out profiles (Fig. 9 and 10) the surface of a fold is made mostly flat. Surface folds are also at least approximately horizontally, if not to take into account facing outwards region 62. Between separate frame 2 and door 3, there are no seals or similar flexible connection, so that an air gap is always maintained.

Therefore, the surface of the groove is provided with such ventilation devices Windows or doors can be cleaned in a simple manner, because in the open position accessible to the eye only a smooth surface. Due to this excludes, of course, is also a potential risk of damage to protruding parts of the device, or so on, there is No need for special variants of implementation and embodiments of devices for a particularly low threshold, which is usual for persons with disabilities.

In the form shown in Fig. 11-16 ventilation device, the shutter 3 is connected with a separate frame 2, respectively, are sealed with respect to it using strips 105, 106, 107, 108. However, the strap 105, 106, 107, 108 have an approximately semicircular cross-section, as particularly evident from Fig. 15 and 16. As follows from the example of the strap 105 in Fig. 11 and 12, the bar 105 shown in Fig. 16 open Polo is the first cut 112 is in the opposite groove 113 of the sash 3.

The upper limit of 105 his flat section 114 adjacent to the approximately vertical segment 115 opposite the groove 113. The center 110 of the rotation and the size of the strap 105 is selected so that in the open position of the sash 3 strap 105 is a flat section 114 closes flush with the groove 116.

As shown in Fig. 13 - 16, actuators 28, 29 is designed as lugs 117, 118 in accordance with the shape of the bars 105, 106, 107, 108. Strips 105, 106, 107, 108 can be connected to terminals 117, 118 using a plug-in connection 119. For this plug-in connection 119 are made in the form of a hollow profile strips 105, 106, 107, 108. Additional fastening strips 105, 106, 107, 108 because of the current in two directions connections flush with the lugs 117, 118 is not required.

The lugs 117, 118 contain shown in Fig. 15 and 16 scenes 30, 31. Angular gear 25 has an insert 120 for a bearing can be rotated strips 105, 106, 107, 108, respectively, lugs 117, 118. Supports are holes, which are provided in the insert and in which are held coaxially with the axis 110 of the axle 121. Valves 26, 27 angular gear 25 are connected to each other deflecting element 122. Valves 26, 27 sakralen valve 26, 27. Due to this, the valves 26, 27 are directed in a straight line in the direction 36 of their displacement.

On the lateral surfaces 125 of the lugs 117, 118 are provided backstage 30, 31 so that when the shift rocker stone or stud 37 lugs 117, 118, or vested in them, the strap 105, 106, 107, 108 can be rotated. However, in the displacement of the valves 26, 27 also provides that the scenes 30, 31 adjacent to each other laths (here, for example, 105 and 108) are to each other. Therefore, the connecting rod 30 has a first segment 126, on which there is no movement of the tip 117. On passing obliquely to the direction 36 of the second offset segment 127 tip 117 is rotated around the center 110. The tip 118, which is connected with a rod 108, the turning movement occurs immediately after the shown in Fig. 15 switching position, with pin or rocker stone 37 is directed to the drawing up. Due to this strap 108 shown in Fig. 15 closed position immediately after the start of the movement of the switch means in an open position according to Fig. 13, respectively, 14.

As shown in Fig. 13, the insert 120 is made rectangular and has on one side of the rectangle, height appropriate to eat such a height, as Planck 105 in the closed position. Due to this, in combination with the vertical movement of displacement or rotary movement provides optimum seal the corner. Opening the shutter can be seen going up to the corner area of a smooth surface of a fold. In connection with executed with the capability to sequentially move the straps 5, 6, 7, 8; 105, 106, 107, 108 also provides the advantage that the strap attached to each other provinces do not move simultaneously, and with a shift in time, respectively, to each other relative to the path of movement of the valves. Due to this, may be, for example, provides that, as shown in Fig. 6, the bar 5 is already fully extended, when the strap 8 end-to-end abuts against the end surface of the rod 5.

When this box 38 corresponds to the width of the groove 11, i.e. in the example of execution according to Fig. 5 the width of the strap 5, as in the example of execution according to Fig. 14 - the diameter of the strap.

In the form shown in Fig. 17 example of execution in the closed position, the actuator 28 of the tip 117 is equipped with A - to V-shaped connecting rod 30. Due to this, the actuator 28 receives another sequence of the switches relative to the total area of movement Cooley is the position (for example, backstage 30 in Fig. 15) are each other. For shown in Fig. 17 30 scenes in the middle switch position provided by the position of the opening with rotation of the ventilation device. Not pictured here is the air gap 9 in the example shown run opens on bars 7 and 8 (Fig. 1), while the rod 5 and 6, except for the middle position switch lead to the locking of the ventilation device.

Strips 105, 106, 107, 108 have ribbon-like seal 109, which is fixed at one longitudinal side to the outer edge of the groove and on the other longitudinal side remote from her longitudinal edge of the flat section 114 of the bars 105, 106, 107, 108. The bar 105, as shown, for example, in Fig. 11, to turn on the external side of the sealing lip 109, so that the seal 109 passes partially perpendicular to the surface 22 of a fold.

You can, of course, arbitrarily combine different forms of these scenes. Along with shows by changing the sequence switch can be a simple way to determine which trims 5, 6, 7, 8; 105, 106, 107, 108 in the closed position, the ventilation of the ventilation device 1 open the air gap.

The tips of the BOM casting zinc under pressure. For completeness it should be specified that the support lugs 117, 118 may be additionally reinforced by a corresponding clutch flush bottom segment angular gear 25 containing the guide 123. This may occur, for example, by a geometric circuit against the load direction along the side surface 125. This can be provided, of course, reduce friction measures.
