Description

The invention relates to an exposed design for a pivoting or folding sash of a window or door with a locking module and a base part mounted on a frame of a window / door frame with a mechanical drive device according to paragraph 1 of the claims.

From DE 102007007997, an exposed design is known for a pivoting or folding sash of a window or door with scissors driven by a mechanical drive device, which comprise a connector with a sash, the mechanical drive device consisting of a spindle, a spindle nut with a gripping pin and a drive motor.

From the patent EP 1437475 A2 also follows another exposed design of the named type.

In addition, thanks to the patent DE 29816102, a structure for moving transversely and linearly moving elements has become known, and on the structure there is an articulated lever, the rotary axis of which is parallel to the articulated axes of the links of the traction chain, is functionally connected with the lever and provides relative movement. In this case, due to the pre-spring-loaded guide element of the chain, the resulting force Fs is formed, which holds the chain in a rigid position, and can thus transmit traction forces.

The disadvantage of this design is that the chain guide acts by the force Fs directly on the chain links, which creates a high friction resistance. In this regard, it becomes necessary greater drive force of the drive mechanism, which negatively affects the cost and the size of the installation space. In addition, there is wear of structural elements, leading to a reduction in their life.

Due to the remoteness of the guide element of the chain, which exerts the force Fs, a large mounting space is required from the corresponding rotary axes of the chain, which negatively affects the cost and complicates the installation.

An exposed design with a locking module and a mechanical drive device of this kind is already known from DE 10157094 C1. The known exposed design comprises a locking module and a base part fixed to the window / door frame frame, on which are located scissors driven by a mechanical drive device, comprising a connector with a window sash, the connector being a connecting member of the drive rod. By means of a mechanical drive device, the locking module is brought into the lock and unlock positions. The mechanical drive device consists of a drive motor that drives the drive spindle rotating around the longitudinal axis and is connected via the connecting element to the scissors in such a way that with proper rotation of the drive spindle around the longitudinal axis the scissors are displaced, and the scissors must be in the closed position. The scissors are connected and disconnected with the locking module through a connecting element located on the scissors, containing a gripping hook, which, by means of a mechanical drive device, automatically switches to the open position and allows manual actuation of the locking and unlocking mechanisms of the swing-out flap. Thus, manual control by means of a handle from the prior art is achievable only by automatically disconnecting in the locked position of the scissors that the locking pin of the drive rod of the locking module with the scissors in the closed position is driven by the drive motor from the unlocking position to the locked position and vice versa, and the gripper the hook automatically comes to the open position.

Due to the use of adjusting scissors based on the principle of a cranked lever, when closing in adjusting scissors there are unfavorable geometrical proportions, which are caused by small mounting dimensions, which requires a large drive force.

Since the built-in design is hidden, the user does not always see that he is dealing with a built-in mechanical drive. If you try to close a hinged window equipped with a mechanical drive by manually controlling it through the locking module or simply by pressing the leaf, the mechanical drive may be damaged, and the window or door may not close under certain circumstances.

In case of failure of the drive motor when the leaf is in the tilted position, closing the leaf is also impossible or is hampered by the resistance of the drive mechanism.

The prior art does not disclose the design for the swing-window or hinged casement window or door with a combined drive, which would ensure that the casement is closed from the down position by manual control.

The basis of the invention is the task of manufacturing an exposed design for a pivoting or folding sash of a window or door of the type initially named, which will provide mechanical closing and folding, as well as manual closing and folding of the sash from the pivoted position, will be technologically simple and economical, and will also make it possible simple, fast reliable and accurate mounting and configuration and will not contain the above-mentioned disadvantages.

The problem can be solved by means of the characterizing part of paragraph 1 of the claims.

By manual control, for example by pressing on the flap, the locking module is manually disconnected from the exposed structure for the swing-window or flap of the window or door, and thus from the base part mounted on the frame of the window frame, which is carried out by means of a mechanical drive device from the exposed design in the tilted position.

In this case, the exposed design, which is manually detached from the locking module, contains scissors with a connecting element for connecting to the leaf, which is a connecting element of the drive rod and, on the one hand, by means of a mechanical drive device, puts the locking module in the locked and unlocked position, and on the other hand, provides manual disconnection if the scissors are in the closed or tilted position, and the locking module is in the locked position whether the floor is open overexposure. In this case, the base part has a housing accommodating a mechanical drive device, the mechanical drive device consisting of a spindle, a spindle nut with a gripping pin and a drive motor, and the spindle nut is manually disconnected from the gripping pin, and also manually or mechanically connected to it.

An improved version provides that the scissors contain a bracket that is longitudinally offset by a straight slot with a pin located on the base part and positioned so that it rotates along the axis of the pin and contains a one-sided flexible chain connected at one end with a bracket and the other end with a mechanical drive device.

To avoid breaking the one-way flexible chain, especially with manual closing, a chain stabilizer is provided, which is also an advantage. For this, a one-sided flexible chain contains a chain stabilizer at the end of the connection with the bracket, and a torque acts on the chain between the bracket and the base part due to the chain stabilizer, which holds the chain in a one-sided flexible position and, accordingly, in voltage.

It is further provided that the bracket and chain, when opened by means of a mechanical drive device, move in the longitudinal direction of the base part on the first part of the stroke, and on the second part of the stroke, when the chain exits in the right corner, the bracket is turned out of the base part. The model of operation of the mechanism achieved in this way when changing the positions of the exposed structure has special advantages due to the small size of the structure, which makes it possible to mount the exposed structure in the window / door frame frames of almost all window / door frame systems.

To achieve a high speed of operation, the mechanism is small, due to its small size, and therefore having low power, the drive motor must operate at optimal load. Therefore, it makes sense to provide for a bracket that is longitudinally displaced at the point of rotation on the body of the base part and is mounted in the center of the chain. The increase in bracket travel achieved in this way and the great force in the chain will ensure an optimal transition to the folding of the sash to move the locking module.

The advantage is also that the spindle is located in the longitudinal direction of the housing and practically coincides in size with the scissors in the locked position and is connected at one end to the drive motor via an elastomeric connection. Due to the peculiarities of the location and shape of the spindle relative to the scissors, the base part mounted in a recess on the frame of the window / door frame does not require a large mounting space, which allows the exposed structure to be mounted in known window and door systems. The elastomeric compound provides vibration absorption and does not allow or reduces unwanted emission of acoustic noise.

In order to ensure a functionally simple and economical detachment of the scissors in the folded position of the leaf from the mechanical drive unit, the spindle is removed from the chain and the bracket in the longitudinal direction of the base part, in the corner from the end position of the lock to the folded position.

It is further provided that the drive motor is in a mount, preferably made of elastic material, and that between the mount and the housing there is an elastic layer, for example of rubber, adapted to the cross section of the housing and the external form of the mount. The absorption of acoustic noise is also ensured through the use of the previously described elastic layers of rubber by creating a movable connection, which is achieved due to the rejection of a rigid metal connection between the body of the base part and the drive motor.

To ensure the simplicity of the design and the economical and technological execution of the exposed design, it is provided that the spindle nut located on the spindle and moved on the housing in the longitudinal direction by means of guide grooves is connected by means of a geometric closure with a gripping pin connected to the chain and moved on the housing by means of guide grooves. The connection by means of a geometrical closure is formed by a recess on the gripping pin and a gripping hook located on the gripping pin, which is under the influence of elastic force, the spindle nut and the gripping pin in the locked position of the exposed structure are connected by geometrical closure, and by mechanical control towards the tilted position, the connection is disconnected .

A further development advantage is that the gripping hook comprises a guiding platform, which, when mechanically controlled towards the tilted position, runs onto a disconnecting sleeve longitudinally movable and secured to the spindle and disconnects the gripping pin from the spindle nut, and when manually operated, the gripping pin is driven to the locked position, and the spindle nut from the open tilted position automatically runs onto the guide platform, moving towards the block position lining, and engages with a gripping pin by a geometrical closure.

In order to ensure connection and disconnection between the mechanical drive device and the exposed structure by means of a simple design, a gripping hook with a spindle nut form an undercut. During mechanical control in the direction of the tilted position, due to the angular shape of the chain to the spindle under the influence of elastic force, pre-stress automatically arises, which, by means of a pulse in the opposite direction from the blocking position, weakens the undercut and, accordingly, the connection. Then, with manual operation, the gripping pin is brought into the locked position, and the spindle nut runs onto the guide platform, automatically moving from the open tilted position toward the locking position, and engages with the gripping pin by geometric locking.

In order for the scissors, being disconnected from the mechanical drive and moved to the final locking position, to maintain a favorable position for connecting to the mechanical drive device, the gripping pin in the folded out or extended position of the sash is held by manual control in the working position of disconnection with the spindle nut of the mechanical drive in the final locking position in the undercut grooves made on the housing. For this, the gripping pin enters the undercut through the spring suspension and, being due to the spring suspension under the influence of force, is fixed in the undercut in a position that allows separation. When actuating the mechanical drive device, when the position of the connection with the scissors has already been reached, the undercutting action can be overcome, so that the exposed structure is mechanically translated into the tilt position.

With manual operation of the sash towards the tilt position and when the mechanical drive unit is disconnected, the gripping pin and spindle nut can be connected.

In addition, when manually controlling the locking module by means of a handle not displayed in the attachment position of the mechanical drive device in the final locking position, the locking module is disconnected from the exposed structure, while the exposed structure remains in the final locking position of the connecting element of the bracket. Such a switching sequence is achieved by simple means due to the greater elastic force of the undercut to the connecting element under the action of the force.

To ensure a constant connection of the chain and the bracket and to keep the circuit in tension when it leaves the base part and when the bracket is turned out, the chain stabilizer consists of two guides located on the bracket and, accordingly, two pressure springs located around the axis of the fixing hole. In addition, the panel with the cam on the lower side and the panel of the upper side, which is in firm connection with the chain link, are connected to a bracket protected from rotation by the cams, which enter the guides. Due to the fit of the panels to the bracket, the panels themselves are interconnected by a geometric and / or power circuit.

For the simplest fit to the sash or frame of the window / door frame and due to the fact that the locking position of the locking module must match exactly the final locking position of the mechanical drive, the base part, in order to compensate for permissible deviations during installation, is positioned taking into account possible movement, thanks to the use of an adjusting screw and a longitudinal groove. A particular advantage is the possibility of fine adjustment if the window or door, for example, has changed shape under the influence of various weather conditions. Subsequent adjustment of the sash to the window frame does not present any problem here either.

To simplify the installation of the base part and to provide the possibility of right- and left-hand use, the base part is made symmetrically in the longitudinal direction of the locking module.

Figure 1 shows the upper part of the sash 3 and the frame of the window / door frame 2 of the window or door with the design according to the invention and generally indicated by the number 1 in Figures 1-13 in the tilting position shown in the present embodiment of the pivoting window or door the casement with the locking module 4 located on the casement 3 and with scissors 40 fixed on it in the exposed position, and on the frame of the window / door frame 2, the base part 5 is hidden mounted in the not displayed, intended for it to be held I notch. The base part 5 has a housing 10, accommodating a mechanical drive device 6, and the mechanical drive device 6 consists of a spindle 18, a spindle nut 19, a gripping pin 20 and a drive motor 21. The exposed structure 1 is located here mainly between the sash 3 and the window / door frame boxes 2 on the upper horizontal rung 41. In this case, the sash 3 and the frame of the window / door frame 2 are located relative to the horizontal and vertical rungs with a fold surface opposite each other and contain supporting pyr other locking elements on the closure unit 4, one of which is located on the frame of the box 2 and the other on the leaf 3 (there is no image). By manual control of the also not displayed handle connected to the locking module 4, the locking elements are relatively movable and can be moved to each other and in the locked position are engaged with each other.

Manual control by means of the handle of the locking module 4, which is not displayed, also provides connection and disconnection between the locking module 4 and the exposed structure 1. In this case, the exposed structure 1 detachable manually from the locking module 4 contains scissors 7 with a connecting element 8 connected to the leaf 3, which is a connecting element the element of the drive rod 9 and on the one hand by means of a mechanical drive device 6 puts the locking module 4 in the lock and unlock position, and on the other hand on the other side provides separation when the exposed design 1 is in the closed position and the locking module 4 is in the locked position.

The scissors 7 comprise, according to FIGS. 1-4, a bracket 11, which is longitudinally offset by a straight slot 12 with a pin 13 located on the base part 5 and positioned so that it rotates along the axis of the pin 14 and contains a one-sided flexible chain 15 connected at one end 16 to the bracket 11 and the other end 17 with a mechanical drive device 6.

The bracket 11 and the chain 15 when opened by a mechanical drive device 6 on the first part of the stroke move in the longitudinal direction of the base part 5. On the second part of the stroke, when the circuit 15 is directed out of the base part 5 into the free control area according to Fig. 4, the chain in the right corner moves relative to the base part 5, so that the bracket 11 is automatically inverted. Due to the kinematic operation of the mechanism, when changing the positions of the exposed structure 1, the small dimensions of the exposed structure 1 are achieved, which makes it possible to mount the exposed structure in the frame of the window / door frame 2 of almost all used window / door frame systems. To achieve a high speed of operation of the mechanism, a small, due to its small size, drive device with limited power should work evenly and at optimal load. Therefore, it makes sense to provide for a bracket 11 longitudinally displaced at a point of rotation on the housing 10 of the base part 5, which is mounted according to FIG. 2 in the center of the chain 15. The thus achieved increase in the stroke of the bracket 11 and the great force in the chain will provide an optimal transition to folding to move the locking module 4 sash 3.

The spindle 18 is located in the longitudinal direction of the housing 10 and practically coincides in size with the scissors 7 in the locked position and is connected at one end 22 to the drive motor 21 by means of an elastomeric connection 23 according to Fig. 13. The drive motor 21 drives the spindle 18, which rotates around the longitudinal axis, and is functionally connected by means of a geometrical closure by the connection 28 to the scissors 7 in such a way that with proper rotation of the spindle 18 around its longitudinal axis, the scissors are offset. Due to the peculiarities of the location and shape of the spindle 18 relative to the scissors 7 according to Fig. 1, the base part 5, mounted in a recess on the frame of the window / door frame 2, does not require a large mounting space, which allows the exposed structure 1 to be mounted in known window and door systems. The elastomeric compound provides vibration absorption and does not allow or reduces unwanted emission of acoustic noise.

In order to ensure a functionally simple and economical detachment of the scissors 7 in the folded position of the sash 3 from the mechanical drive unit 6, the spindle 18 is removed from the chain 15 and the bracket 11 in the longitudinal direction of the base part 5, located in the corner according to Fig. 8. It is further provided that, according to FIG. 13, the drive motor 21 is located in the mount 24, preferably made of elastic material, and that between the mount 24 and the housing 10 there is an elastic layer 25 adapted to the cross section of the housing 10 and the external form of the mount 24. Acoustic absorption noise is also ensured through the use of the previously described elastic layers 24, 25 by creating a movable connection, which is achieved due to the rejection of a rigid metal connection between the housing 10 of the base part 5 and driven motor 21.

To ensure simplicity of design and economical and technological execution of the exposed design 1 according to Figs. 11-12, it is provided that the spindle nut 19 located on the spindle 18 and moved on the housing 10 in the longitudinal direction by means of the guide grooves 26 is connected by means of a geometrical closure by a connection 28 with a gripper a pin 20 connected to the chain 15 and moved on the housing 10 by means of the guide grooves 27. The connection by geometrical closure is formed by a recess 42 on the grip pin 20 and is located attached to the gripping pin 20, which is under the influence of elastic force by the gripping hook 43, 44, the spindle nut 19 and the gripping pin 20 in the locked position of the exposed structure 1 are connected by a geometric closure, and by means of mechanical control towards the tilted position, the connection 28 is disconnected.

A further development advantage according to FIGS. 5-7 is that the gripping hook 43 comprises a guide platform 45, which, when mechanically controlled towards the tilted position, runs onto the disconnecting sleeve 47, longitudinally movable and secured to the spindle 18, and disconnects the gripping pin 20 from the spindle nut 18, moreover, when manually operated, the gripping pin 20 is brought into the locked position, and the spindle nut 18 from the open tilted position automatically runs onto the guide platform 45, moving towards the locking position, and enters into a compound 28 by engagement with the gripping pin 20 by interlocking.

In order to ensure the connection and disconnection between the mechanical drive device and the exposed structure by means of a simple design according to Figs. 8-10, the gripping hook 43 with the spindle nut 19 form an undercut. When mechanically controlled towards the tilted position, due to the angular shape of the chain 15 to the spindle 18, a tensile stress automatically arises, which, by means of a pulse in the opposite direction relative to the blocking position, weakens the undercut 48 and, accordingly, the joint 28, the pin 20 is brought into the locked position, and the spindle nut 18 runs onto the guide platform 46 and enters the connection 28 by engagement with the gripper m pin 20 by interlocking.

In order for the scissors 7, being disconnected from the mechanical actuator 6 and moved to the final locking position, to maintain an advantageous position for connecting to the mechanical actuating device, the gripping pin 20 according to FIG. 11 and FIG. 12 in the folded out or extended position of the sash 3 is held by manual control in the operating position of separation from the spindle nut 19 of the mechanical drive 6 in the final locking position in the undercut 49 made on the housing 10 of the guide grooves 27. For this, the gripping pin 20 enters through the spring suspension into the undercut 49 and, being due to the spring suspension under the influence of force, is fixed in the undercut 49 in a position that allows separation. When actuating the mechanical drive device 6, when the position of the connection with the scissors 7 according to FIG. 4 has already been reached, the undercutting 49 can be overcome, so that the exposed structure 1 is mechanically translated into the tilt position.

With manual control of the sash 3 in the direction of the tilt position and when disconnecting the mechanical drive device 6 according to FIG. 11, the gripping pin 20 and the spindle nut 19 can be connected.

In addition, when manually controlling the locking module 4 by means of a handle not displayed in the attachment position of the mechanical drive device 6 in the final locking position according to FIG. 4 and FIG. 13, the locking module 4 is disconnected from the exposed structure 1, while the exposed structure 1 remains in the final position blocking of the connecting element 8 of the bracket 11. This switching sequence is achieved by simple means due to the greater elastic force undercut 49 to the connecting element 8, tries dyaschemusya under force.

In order to avoid breaking the one-sided flexible chain 15, according to Fig. 5, especially when manually closing, a chain stabilizer 29 is provided. For this, the one-sided flexible chain 15 contains at the end 16 of the connection with the bracket 11 a chain stabilizer 29, and on the chain 15 between the bracket 11 and the base 5, due to the stabilizer of the circuit 29, a torque is applied that holds the chain 15 in a one-sided flexible position and, accordingly, in voltage.

To ensure a constant connection of the circuit 15 and the bracket 11 and in order to keep the circuit 15 in tension when it leaves the base part 5 and when the bracket 11 is turned out, according to FIG. 1 and FIG. 4, the circuit stabilizer 29 consists of two located on the bracket 11 guides 30 and, respectively, two pressure springs 31 located around the axis 32 of the fixing hole 33. In addition, the panel 35 with the cam 36 on the lower side 34 and the panel 38 of the upper side 37, which is in firm connection with the link 39 of the chain 15 are connected anti-agility Ivanov manner with bracket 11, and the cams 36 enter the guide 30. In the drawings, not shown, that the connection circuit 15 with a bracket 11 carried by the stabilizer circuit 29 preferably riveted.

For the easiest fit to the sash 3 or frame 2 of the window / door frame and due to the fact that the locking position of the locking module 4 must match the locking position of the mechanical actuator 6, the base part 5, thanks to the use of an adjustment screw and a longitudinal groove not shown 50, in order to compensate for installation deviations, it is positioned taking into account the possible movement of the adjusting screw in the longitudinal groove 50. A particular advantage lies in the possibility of precise adjustment ovki if a window or door, for example, change shape under the influence of different weather conditions. Subsequent adjustment of the sash 3 to the frame 2 of the window frame also does not present any problem here.

To simplify the installation of the base part 5 and to provide the possibility of right-and left-hand use, the base part 5 is made symmetrically in the longitudinal direction of the locking module 4.
