Description

The invention relates to a device for opening and closing windows on caravans, motorhomes and the like, comprising an actuating rod, which interacts with locking devices which are arranged on a frame of the window.

In the devices of the type considered here, on the one hand, it is important for the operational safety that the windows should be open in different angular positions; at the same time, the windows should be locked in the various open positions to prevent unauthorized full opening of the windows by unauthorized persons or wind adjustment of the opening angle.

A device of the type mentioned is from the DE 197 25 677 C2 known. The locking devices can be operated via a common operating rod. The actuating rod is pivotable. By pivoting the unlocking and locking or the opening and closing of the respective window takes place. The known device meets the demands made on it. The disadvantage, however, has been found that the pivoting of the actuating rod is difficult under certain circumstances. In addition, the adjustment range of the window is limited in the known device.

A device of the type mentioned is also from the DE 203 16 827 U1 known. The locking devices can be operated via a common operating rod. The actuating rod is rotatable. Due to the rotation of the unlocking and locking and the opening and closing of the respective window takes place. The known device meets the demands made on it. The disadvantage, however, has been found that only 3 can be adjusted by positive locking secure positions.

A device for unlocking a canopy is from the DE 20 2004 014 761 U1 known by means of a double cable, which simultaneously releases two spring latch. The disadvantage, however, has been found that the device is difficult to move when not simultaneously releasing the spring latch.

A device for inhibiting the position of a sash of a swing and / or folding roof windows is from the EP 1 335 018 A2 known. However, the window is not hinged at one end but centrally mounted. The disadvantage is that a transmission in a wind exposed to the wind of a car window generates no wind wedge, but horizontally installed a considerable windage surface offers. It would also collect rain while driving and direct it into the vehicle interior.

Another roof hood device is from the DE 203 16 827 U1 known. However, this has only a few locking positions. In addition, a twisting of the handle bar is required to operate the device.

The invention aims to remedy this situation. The invention is based on the object to provide a device for opening and / or locking windows on caravans, motorhomes or the like, on the one hand allows easy and reliable handling, on the other hand has a large adjustment. According to the invention, this object is solved by the features of claim 1.

The invention provides a device for opening and / or locking windows on caravans, motorhomes and the like, which is easy to handle and also causes a large adjustment of the window. The ease of use is created by the fact that the controls and thus the internal parts of the locking devices perform a vertical or horizontal movement, so that can be dispensed with the pivotal movement of the actuating rod. In addition, the arrangement of the locking devices on guide profiles offers the possibility to allow an adjustment over the entire length of the guide profiles.

In a further development of the invention, positive locking devices are provided. The interlocking locking devices provide an extremely high degree of security in the lock, so that in particular unauthorized opening or adjustment by wind of the window is much more difficult.

In another embodiment of the invention, frictional locking devices are provided. The use of frictional locking devices offers the possibility of creating a completely stepless adjustment of the opening angle of the window while at the same time reliably locking.

Advantageously, the actuating rod for unlocking or locking with a vertical stroke is movable and horizontally displaceable horizontally to open the window. With the help of the vertical movement possibility of the actuating rod an immediate transfer of movement to the vertically movable and biased in the stroke direction inner brake parts of the locking devices is possible, so that no additional mechanism for transmission the lifting movement is required, whereby the construction of the device according to the invention is simple and thus inexpensive, but at the same time reliable.

In an advantageous embodiment of the invention, a cable is arranged in the actuating rod. The cable offers the possibility to reliably transmit a triggering of the actuating rod to the locking devices. At the same time a lightweight mechanism is created by the use of the cable.

In another embodiment of the invention, an actuating lever is arranged in the actuating rod. The use of the operating lever provides a very stable and thus extremely reliable transmission of the triggering movement.

In a preferred embodiment of the invention, the actuating rod is pivotally connected to the locking devices. Due to the articulated connection between the locking device and actuating rod tilting when opening and 1 or locking the window is prevented, so that an extremely reliable actuator is created by the articulated connection.

Other developments and refinements of the invention are specified in the remaining subclaims. Three embodiments of the invention are illustrated in the drawings and will be described in detail below. Show it:

The exemplary embodiment in 1 selected roof hood of a caravan has a window 1 on which hinged to a window frame 2 is arranged. The frame 2 is in the roof three taken in the caravan. On two sides of the window frame 2 are leadership profiles 4 arranged. It is a device for opening and / or locking the window 1 provided, which is an actuating rod 5 includes, which with locking devices 6 interacts. Between the locking devices 6 and the window 1 is a connection with the help of supports 7 created, both at the locking devices 6 as well as at the window 1 are hinged. By moving the operating rod 5 along the guide profiles 4 a change in the angle of the window occurs 1 to the window frame 2 , causing the window 1 can be opened completely or partially.

The guiding profiles 4 are formed differently depending on the embodiment. In the embodiments, as in the inter alia in the 5 and 6 are shown, the guide profiles 4 the approximate shape of a T-profile. This is a vertically oriented guide rail 41 formed the locking devices 6 when moving leads. As in the embodiment according to 15 To recognize the leadership profiles 4 on her the guide rail 41 opposite side with a toothing 42 be provided, which - as explained below - contributes to the locking of the device. As well as the embodiments of the 15 and 16 it can be seen in the area of the end of the guide profiles 4 in the guide rail 41 a reduction 43 provided, which represents the end position of the travel of the device.

The operating rod 5 in 42 is designed as a hollow profile. It extends between the at the guide profiles 4 movably arranged locking devices 6 and is connected to them. The operating rod 5 is provided depending on the embodiment with a transmission mechanism. This is in three a button 51 on the operating rod 5 arranged in the embodiment extends only over a short portion of the actuating rod. In a modification of the embodiment, it is also possible to use the button 51 over the entire width of the actuating rod 5 expand or two or more buttons on the actuator rod 5 provided.

The button 51 interacts with the transfer mechanism. In the embodiment A after three . 5 and 6 is the transmission mechanism of a cable 52 formed in the operating rod 5 is arranged. The cable 52 is about roles 53 guided and at its two free ends with cylindrical end nipples 626 , which are in cylindrical pockets of the brake inner parts 624a lie with the locking devices 6 connected. In the embodiment according to three can be seen that by a vertical movement of the button 51 by means of a vertical guide 56 only possible is a movement of the cable 52 is triggered. Because the free ends of the cable 52 are vertically aligned, such a movement of the cable leads to a vertical movement of the preloaded in the stroke direction inner brake parts 624a the locking devices 6 like this 5 and 6 can be seen. It is in 5 presented the training in which the button 51 in his starting position 1 Locking position is located and thus neither on the button 51 nor by the transmission of the button movement by means of the cable 52 a movement on the locking device 6 is exercised. In contrast, in 6 the position shown in which a vertical force on the button 51 and thus over the cable 52 also a vertical movement on the brake inner parts of the locking device 6 exercise, which unlocks it.

When in the embodiment B in 4 and 7 shown actuating rod 5 is also a button 51 intended. The button 51 However, in this embodiment is an operating lever 54 in conjunction, which also in the operating rod 5 is arranged. In the embodiment, it is the operating lever 54 around a U-shaped profile, which is in the direction of the guide profiles 4 rejuvenated. Due to the rigid connection of the button 51 with the operating lever 54 performs a vertical movement of the button 51 by means of a vertical guide 56 is only possible, also to a vertical movement of the actuating lever 54 , whereby a vertical movement on the preloaded in the stroke direction inner brake part 624b the locking device 6 is exercised, like this 7 can be seen. It has the brake lever 54 at its outer ends cylindrical articulated arms 57 leading to a hinged connection between operating levers 54 and the cylindrical bag in the brake inner part 624b to lead.

Like that 5 to 7 can be taken are in the field of locking devices 6 compression springs 8th in the stroke direction of the brake inner parts 624a , b and c arranged, leading to a return of the locking devices 6 in their locking position after release of the button 51 to lead. Thus, also the button is 51 under the influence of the springs 8th , so that this also automatically returns to its original position by this bias.

In a modification of the embodiments A and B, it is also possible, the actuating rod 5 form without a button and instead the entire operating rod 5 vertically movable to arrange, as in the embodiment C in the 4.2 and 8th to 16 shown. As a result, the release of the locking device is carried out by a vertical movement of the entire operating rod 5 , In such an arrangement, accordingly, a pulling of the actuating rod 5 in the direction of the bottom to a release of the locking device 6 , whereby a shift is possible. By a kinematic reversal, this can also be done by pressing upwards. As in the 4.2 and 8th to 16 recognizable, is the operating rod 5 designed as a hollow profile, firmly on the ends of the brake inner parts 624c is plugged. In this one-piece design, in principle, the actuating rod 5 at their two the locking devices 6 facing ends each with a collar 55 Mistake.

The locking devices 6 include a sliding head 61 that is on the top of the guide profiles 4 is arranged movable. The sliding head 61 has a recording 611 on, in which the supports 7 articulated via an axle pin 615 are arranged. The pictures 611 are designed as a slot and therefore provide the supports 7 the possibility of reaching the final position on the guide profiles 4 to move from a driving position in the slot in an end position in the slot, the complete closure of the window 1 allows. The closing is done by the boom 614 on the sliding head, which is in a locking pocket 11 can enter the window. In the sliding head 61 is a backdrop stone 612 arranged under the influence of a spring arm 613 stands like this 8th and 16 can be seen. The spring arm 613 causes a vertical force on the sliding block 612 , This vertical force ensures that the sliding block 612 when reaching the lowering 43 in the leadership profile 4 enters this and defines the end position of the travel, as in the 8th and 16 is recognizable. Through the inner contour of the sliding block 612 become 2 positions of the axle pin 615 in the respective end positions of the slot of the recordings 611 for the supports 7 fixed. This creates in the Kulissenstein 612 a driving position for adjusting the opening angle and an end position for locking.

The locking devices 6 consist in addition of a braking device 62 on the bottom of the guide profiles 4 is arranged movable. Here is the sliding head 61 with the brake housing 622 the braking device 62 firmly connected to a unit. The braking devices 62 include a brake inner part 624c that in the brake housing 622 biased by compression springs and arranged vertically movable in the stroke direction. At the brake inner part 624c on the one hand, on the other hand on the brake housing 622 The springs are supported 8th from. In the embodiment of the 5 to 7 it is a frictional locking device; in the 8th to 16 a positive locking device is provided.

The frictional locks are each with at least one rubber element 621 or a similar adhesive plastic element provided by the springs 8th pressed, in contact with the bottom of the guide profiles 4 can occur. In the embodiment according to 7 is the rubber element 621 formed by a strip at the top of the brake inner part 624b is fitted in a groove provided there.

In the positive locking technique are on the guide profile 4 facing side of the brake inner part 624c ribs 623 intended. Ribs 623 grab, through the springs 8th pressed, in the locked state in the toothing 42 on the guide profiles 4 (see. 8th and 16 ). Ribs 623 have sloping flanks to secure entry into the teeth 42 on the guide profiles 4 and to allow a comfortable operation.

In the embodiment of the 4.2 and 9 to 16 the actuation of the device according to the invention by a lifting movement of the actuating rod 5 ; the operating rod 5 has no button in this embodiment 51 on. By a vertical movement of the actuating rod 5 becomes a stroke movement of the brake inner part 624c in the brake housing 622 executed. In order to clamp the brake inner part 624c To prevent, are on the outside of the brake inner part 624c guide ribs 625 provided, which have a spherical training, as in particular in 11 is apparent. At the same time, it is at the insertion end of the brake inner part 624c in the operating rod 5 intended covenant 55 also on his the locking device 6 facing side performed crowned. Like that 13 and 14 can be seen, leads the total crowned execution in the area of the transition between the actuating rod 5 and locking device 6 to an articulated connection, which allows a recognizable in the above figures tilt angle. As a result, tilting in the operation of the device is allowed, but prevents the terminals by the spherical design. In the embodiment of the 4.2 and 13 to 15 is the operating rod 5 with the brake inner part 624c rigidly connected. As a result, performs a lifting movement of the actuating rod 5 automatically to a lifting movement of the brake inner part 624c ,

In all embodiments, the brake inner parts lead 624 a short stroke to release the locking position. The stroke is through stops 627 in the brake housings 622 limited (cf. 12 ), so with uneven stroke by the operation in the two lateral brake devices 62 (see. 1 . three . 4 and 4.2 ) One side first against a stop 627 moves and then the further operating movement only to a hub in the braking device 62 the other side leads. Thus, the control element in the form of the button 51 or the entire operating rod 5 moved to the stop, the locking devices 6 unlocked on both sides.

In the embodiment according to 17 the device is shown with a horizontally movable latch. Here is the gearing 42 the guide profiles 4 vertically on the frame 2 arranged. The stroke of the actuating rod 5 can be done vertically in a known manner; through the mechanics in the bar 5 the deflection of the vertical movement of the button takes place 51 or the operating lever 54 in a horizontal movement of the brake inner part 624d as indicated by the arrow in principle 17 is clarified. This design allows an equally reliable and easy-to-use latch.

The device according to the invention allows a comfortable and reliable operation of the windows on caravans, motorhomes or the like. Due to the exclusively vertical movement of the braking device after the 1 to 16 including only vertical movement of the button 51 or the entire operating rod 5 an extremely easy-to-use device is created, which at the same time very reliable allows both an optionally only partial opening of the window as well as a full opening with simultaneous locking to prevent improper operation or adjustment by wind. With the present invention, an opening angle between 0 and 80 degrees can be achieved. Thus, with the device according to the invention, the usable adjustment range is substantially increased in comparison with the solutions known from the prior art with ranges between 0 and 55 degrees.

In contrast to the known roof hood device according to DE 203 16 827 U1 have the embodiments shown here not only 2 or 3 locking positions, but much more. These latches are released by releasing the actuating rod 5 or the button 51 or the operating lever 54 achieved by means of the bias of the springs on the brake inner parts. There is no additional movement required, such as twisting the handlebar.

In addition, a continuous adjustment of the locking positions and thus the opening angle is possible when using the frictional locking device. Depending on the design of the interlocking locking device, in particular the pitch of the toothing 42 in conjunction with the dimensions of the ribs 623 is also a finely divided setting of locking positions possible. For example, on the guide rail 41 a gearing with z. B. 50 to 70 positions can be provided, resulting in a very sensitive adjustability. In addition, when using the lowering 43 in the guide rail 41 in conjunction with the spring-loaded sliding block 612 on the sliding head 61 a fixed fixation of the end position and a fuse in this position caused by the risk of unauthorized opening is additionally prevented.

In addition, when using the button 51 in conjunction with the cable pull 52 or the operating lever 54 with the cylindrical articulated arms 57 ensures that on the brake inner parts 624a or 624b only a vertical force is exerted. This is by pressing the button 51 applied force and their only vertical transmission to the brake inner parts 624a out three . 5 and 6 or 624b out 4 and 7 allows. As a result, tilting and subsequent jamming of the mechanism is excluded. In the rigid connection of the actuating rod 5 with the brake inner part 624c according to the embodiment in the 4.2 and 9 to 16 tilting is permitted, the clamping of the mechanism due to the crowned design of the guide ribs 625 as well as the federal government 55 but also prevents, since this embodiment is equal in function to a joint.
