The invention relates to a pressing device for bandsei installation between a sash and a frame ner door, a window or the like., at which or the Flü gel with respect to the frame between a closing and an open position is pivotable with a frame side holding unit with at least one locking web and a sash locking unit with we at least a Verrie held with one end and rotating gelungsflügel, with both units in the closed position in Meaning of a pressure of the wing on the frame to each other reach behind and the two units are hidden in the fold stood between the sash rebate and the frame rebate are arranged.

A pressing device of the type mentioned is out known from DE 195 18 253 A1. It consists of a stop element on the one hand and one, an actuator and one Bolts, which are connected to each other via a gear, having pressing part on the other hand. So that a preload  on the seal between the sash and frame can be brought, the actuator moves in Direction of the sash level or frame level to the glare frame or sash frame and the end of the latch at the on press perpendicular to the sash level or frame level, wherein the end of the latch has a projection on the holding element reaches behind and ver sash and frame tense.

The disadvantage is that by using a gear for the actuation of the bolt disturbs the pressing device is due. Because of the size relationships of the Pressing device and the fine adjustment of the bolt itself, the gearing of the gearbox must be very fine. The has the consequence that with large power transmissions of the bolt the gearing can break out. In addition, Ver dirt and paint residues the effectiveness of the transmission restrict.

A pressing device is also known from DE 42 10 753 C2 known. It consists of two parts of the device Closed position in the sense of a pressure on a wing reach behind each other and conceal the Fold distance between sash and frame are.

The disadvantage is that the device parts up complicated builds, so that occurring mishandling or dirt affect the operability of the pressure device can. Another disadvantage is that when pressing a high lateral sliding friction of a seal Riegel occurs on one of the devices.

It is therefore the task of a pressing device of the type mentioned at the outset so that the Locking process easy and trouble-free to carry out is.  

According to the invention, this object is achieved by

• - That the frame-side holding unit as a U-shaped Holding groove is formed, the groove base on one End through the locking bar and on the opposite lying end is limited by a stop bar and
• - That with the locking wing single-ended and rotatable a control wing is connected which is provided with a control curve that at the transition of the wing from the open to the closed position and vice versa returns past a sensing pin.

The advantages achieved with the invention are in particular the other in that the locking wing and the control wing through a double joint and the control curve on the control wing being controlled. At the transition of the wing from the open in the closed position the control cam on the sensor lead past. Here the control wing is on the Groove base surface and slides on it towards An flapper, at the same time the locking wing in Is moved towards the locking bar. When you reach the The locking leaf engages behind the closed position by force conclusively the locking bar and presses the wing on the Frame. This allows all in seals arranged in this area are fully effective unfold. The tax office can provide the relief of the groove base Movement of the control wing can be adjusted. Advantageously is it straight or flat.

A window is shown in FIG. 1. It consists of a wing 2 , which is rotatably and tiltably held by a pivot bearing 6 and a scissor bearing 7 on a frame 3 . A function adjustment of a fitting (not shown) is carried out via a handle 8 and the window is opened in the direction of rotation. In the case of larger windows in particular, the bars 4 , 5 of the sash 2 and the frame 3 are relatively long. Here, the two hinge parts 6 , 7 are not sufficient to properly hold the wing 2 pressed against the frame in a closed position. Especially with wind load on the wing 2 , this leads to a deflection of the spar 4 so that the seals lying between the wing and the frame are relieved and both are no longer sealed against each other. In addition, the large distance between the pivot bearing 6 and the scissor bearing 7 represents a weak point in terms of security against break-ins. With the help of the simplest tools, the spar 4 of the wing 2 can be separated so far from the spar 5 of the frame 3 that the wing in the end can be pushed out of the frame.

For these reasons, a pressing device 1 is arranged between the pivot bearing 6 and the scissor bearing 7 .

Such a pressing device 1 is in different opening angles α in the drawings 2a and 3 to 5 Darge. As particularly FIG. 5 shows, the apparatus 1 Andrückvor hidden in a fold spacing 40 between the sash 41 on one hand and a sash rebate 42 walls disposed hand, face down.

The structure of the pressing device 1 will be described below in particular with reference to FIG. 2b.

Then the pressing device 1 consists of

• - A holding unit 10 and
• a locking unit 20 .

The holding unit 10 is located on the frame fold 42 . It is designed as a U-shaped retaining groove 11 , which consists of a substantially flat or planar groove base 12 , which is limited on one side by a locking web 13 and on the opposite side by a striking web 14 . The stop bar 14 is also part of a seal holding unit in which a sealing profile 16 is held with a sealing lip 36 . The transition from the stop web 14 to the groove base 12 is cut out.

The locking unit 20 is arranged on the sash 41 .

It consists of a holding body 31 , which can be made of plastic, metal or the like. In the holding body 31 , a guide recess 43 is made . Under the guide recess 43 there is a wing movement recess 30 . In the guide recess 43 a Federele element, which is designed as a coil spring, is arranged in front of which a sliding body 29 is positioned. The sliding body 29 is cylindrical and merges into a cone tip.

Essential elements of the locking unit 20 are

• - A locking wing 21 and
• - A control wing 22 .

The locking wing 21 is essentially ellipsoidal, the right side of the elipsoid, as shown in FIG. 2b, being cut off along a straight line, so that a wing tip 21 exists. The wing tip 21 is rounded. On the locking wing 21 a beat pin 27 is arranged. The wing tip 21 'opposite end of the locking leaf 21 is rounded, where at the center of the semicircle of this rounding a slot opening 25 begins through which a slide pin 26 protrudes, which is held in the holding body 31 . Between the locking wing 21 and the control wing 22 , a sensing pin 24 is arranged. This sensing pin 24 bears against a control curve 23 of the control wing 22 . The control wing 22 is a strand-shaped body which ends in a semicircular sensing curve 22 'on one side. The opposite side has a curve that is the same as the curve 22 '. The control wing 22 is held by a pivot 32 , which is arranged in the region between the center of the pin 26 and the wing tip 21 'on the locking wing 21 . While one side of the control wing has a straight course, as he already mentioned, the opposite side has the control curve 23 . This is, as Fig. 2b shows, designed as a survey, so that the control wing in plan view resembles the side view of a notchback car.

As shown in FIGS. 2a and 2b show, are located at the opening angle α = 20 ° the latch and the control vanes 21, 22 in their initial position. This is effected by the spring element 28 via the sliding body 29 to Ver Reset of wings 21 against the pin 24 and the filling STEU erflügel both between the filling pin 24 and the stop pin presses 27th

As shown in FIGS. 2a and 3 to 5, a web height B, a Endsteghöhe C and an increased height D. stand between the Get men 4, 5 of the sash 2 and the window frame 3, a Drehab was A, A comparison of Fig. 5 and 6 shows that with the aid of the holding body 31, the locking unit 20 can be adjusted relative to the holding unit 10 by changing the entry height D. In the drawing in FIG. 5, the entry height D = 0 cm, while in FIG. 6 an entry height D1 can occur during adjustment. In this case, the entry height D1 is approx. 4 mm. As a result, the rotation distance A changes to a rotation distance A1 with a shorter length. The web height denoted by B1 and the end web height denoted by C1 are equal to B and equal to C. A rebate distance denoted by 40 , also called rebate clearance, can be adjusted in this way.

On the spar 4 , as shown in particular Fig. 2b, a wing sealing profile 34 with a profile lip 35 is used.

The function of the pressing device 1 shown in FIGS . 2a to 6 will be explained in the following.

As shown in FIG. 2a, as already mentioned, with an opening angle of the wing 2 relative to the frame 3, the locking unit 20 assumes an initial position such that, due to the spring force of the spring element 28, both wings 21 , 22 against the one designated by 21 and 24 Strike the pin.

In Fig. 3, the opening angle α is reduced to 8 °. Here at the control wing 22 with its discharge round 22 'on the groove base 12 and detaches from the striking pin 27th At the same time, the sensing pin 24 senses into the control curve 23 and presses the wing tip 21 ′ of the locking wing 21 in the direction of the locking web 13 .

In Fig. 4, the opening angle α has been reduced to 4 °. The control wing 22 is with its discharge round 22 'further in the direction of the stop web 14 on the flat groove bottom surface 14 slipped. At the same time, the sliding pin 26 has positioned itself in the slot 25 to the other side in terms of stop. The locking wing 21 has approached further with its wing tip 21 'in the direction of the locking web 13 . Although both wings 21 , 22 have almost reached their end position, the sealing lips 35 and 36 do not touch either the spar 4 or the spar 5 .

In Fig. 5 of the wing 2 has reached 0 ° with respect to the frame 3 at an opening angle = the final closed position. The sensing pin 24 has reached the end of the control curve 23 . The control wing abuts the stop bar 14 in a force-fitting manner with its rounded curve. With its opposite end, it presses the locking wing via the pivot 32 with its wing tip 21 ′ in a force-locking manner behind the locking web 13 . As a result, the spar 4 of the wing 22 is pressed against the spar 5 of the frame 3 . As a result, the profile lip 35 engages intimately on the pressing surface 33 designated 38 and the sealing lip 36 on the further pressing surface designated 37 of both the spar 4 and the spar 5 .

In Fig. 7, a Andrückvor direction 100 is shown as a further embodiment.

The pressing device 100 , like the already described pressing device 1, is arranged at a fold distance 140 between a sash rebate 141 on the one hand and a frame rebate 142 on the other hand.

it consists of

• - A holding unit 110 and
• a locking unit 120 .

The holding unit 110 is constructed in the same way as the holding unit 10 , ie it is formed as a U-shaped holding groove 111 , the groove base surface 112 of which is delimited on one side by a locking web 113 and on the other side by a stop web 114 . Here, too, the stop web is at the same time part of a seal holding unit 15 and is cut in the transition region to the groove base surface 112 .

The locking unit 120 has a holding body 131 , which consists of a cylindrical part, into which a guide recess 143 is made. In the guide recess 143 , a spring element 128 and a sliding body is positioned by 129 . At the cylindrical part of the holding body 131 is followed by a further substantially cylindrical part, but which has a larger diameter water. He is hen with a wing recess 130 verses, inside which a locking wing 121 and a control wing 122 are arranged.

The locking wing 121 is a rectangular body, one side of which is chamfered. This creates a wing tip 121 . The wing tip 121 opposite end is rounded in a semicircle, with a sensing and pivot pin in the center of this semicircle, where by the locking wing 121 as well as the locking wing 21 is rotatably held on one side.

Approximately in the middle between the sensing and pivot pin 124 and the blade tip 121 of the control wing 122 is disposed on the locking wing 121st This has a Dutch clog-like configuration. The relief, in particular of the front part of the clog, forms a control curve 123 . A rounded curve 122 'is located opposite the wooden shoe tip. With the aid of a shaft body height F, a control holding body height G, a clearance height H and an insertion height I, the pressing device 100 is adjusted at the folding distance 140 , also referred to as folding air. The adjustment is possible here, as already explained for the pressing device 1 , by changing the insertion height I.

The operation of the pressing device 100 is similar to that of the pressing device 1 . At the transition of the wing 2 from the open to the closed position, the opening angle between them decreases. Here, as shown in FIG. 7, the sensing round 122 first hits the groove base surface 112 . When it is closed further, it slides on in the direction of the stop web 114 . At the same time, the sensing and pivot pin 124 senses the control cam 123 and, in the final state, positively places the wing tip 121 behind the locking web 113 . This results in a profile lip is pressed in a sealing 135 of a wing sealing profile 135 against the member 4 and a sealing lip 136 against the spar. 5
