Description

The invention relates to a device for storing energy in the construction of a window or door according to paragraph 1 of the restrictive part of the claims. Advantageously, the invention relates to a device for a tiltable parallel sliding window / door sash or a tapering parallel sliding window / door sash. In the future, the opening and closing part will be called the sash, and the fixed part is the frame.

The tasks of the device for energy storage include ensuring the movement of the sash to the frame from a parallel retarded position in the closing direction, securing at the end point of the retarded position and providing controlled parallel opening. Due to this, when opening the window by moving to the final parallel-deferred position, it is possible to control the opening speed and help to reduce the arising forces that adversely affect the fittings, as well as reduce impact noise. The forces arising in a system of this kind depend on the initial speed and mass and lead to overloading the fittings, especially large windows and doors, and also cause shock noises when moving to a parallel open position. In addition, the large weight of the sash complicates the closing process when moving from a parallel open position. In the future, the task is to provide an easier closing process when moving from a parallel-deferred position to an adjacent closing position by using an easily mounted energy storage device.

The energy storage device also forms an additional obstacle that prevents the window from slamming under gusts of wind.

As already noted, the invention relates to an energy storage device used to provide easier operation of a window or door when moving from a parallel-deflected position to an adjacent closing or tilting position. In such situations, it is known to use fittings that transmit the movement of the control handle through the lever transmission of the drive rod and an angular switch to more than one or all sides of the leaf. This allows for several points located throughout the sash to ensure its blocking by means of a locking device and its parallel-deflected folding or sliding position relative to the frame by means of the exposed design.

In this area, one can state an increase in interest in comfort and, consequently, in reliability. To meet growing demands, it is necessary to expand the range of functions of structural components.

Fittings of this kind are already known from the application EP 0103725 B1. Moreover, the known construction comprises accessories for at least being parallel-dismantled by means of sliding brackets of the sash of a window or door, the lower bracket or lower brackets being located, on the one hand, on the lower transverse crossbeam of the sash, and on the other hand, on the carriage and are installed in a position that allows rotation. In addition, the design comprises a locking mechanism for lower brackets in a parallel-lateral position, which consists of a locking element interacting with a locking clamping device, the locking mechanism being actuated by moving the sash in the closing direction with respect to the fixed frame by means of a fixed, inclined thrust protrusion. To facilitate the closing process from a parallel-deferred position, a coil spring is installed between the guide bracket and the retractable bracket, which exerts pressure on the guide bracket towards the lock position.

Due to this measure, movement is provided from the parallel-deflected position of the sash to the adjacent closing position. However, to provide this distinctive advantage, a coil spring is provided, mounted in a known construction on a rotatable connection between the guide bracket and the extendable bracket.

For this reason, a large installation space, i.e. installation height, which negatively affects the stability of the structure. In the future, fixing the coil spring is possible only as the installation of individual parts. That is, subsequent installation or replacement is associated with large financial costs associated with the replacement of the entire exposed design. Based on the choice of the coil spring and due to the limited mounting space for the provided small-sized spring, the fittings can automatically move only a small distance from a parallel-deflected position to an adjacent closing position, which does not bring significant relief.

In addition, the HAUTAU device, described in the HAUTAU ATRIUM SP komfort brochure, is known for moving the leaf from a parallel-deflected position to an adjacent closing position. This device is laborious in terms of design, contains a large number of parts and its manufacture is associated with high costs. In addition, this device requires a large installation space, which at the same time negatively affects the appearance.

The basis of the invention is the task of manufacturing a device for ensuring and facilitating the operation of a window or door, facilitating the movement of the sash from a fixed parallel-left position in the direction of closing to the frame, which will be economical, and will also make simple, quick reliable and accurate mounting and adjustment and not Will require a large installation space.

To solve this problem, fittings are provided for a window or door sash that is retractable in a position at least close to parallel and horizontally moved in this parallel-retracted position parallel to the opening in the wall using the exposed structure in the direction from the opening in the wall from the closed position, for example from a fixed frame. At the same time, at least one exposed design located on the lower transverse crossbeam of the sash is supported by the running carriage on running guide rails located parallel to the hole and / or frame, and is limited by an appropriately positioned sliding bracket mounted in a rotational position in a parallel exposed opening using the triggered locking mechanism of the guide bracket. The locking mechanism consists of a locking element that interacts with the locking clamping device, and is actuated as a result of the sliding movement of the sash relative to the stationary frame in the closing direction by means of a thrust bearing, the guide bracket being pivotally connected to the closing sliding bracket, forming a rotary axis, and the locking clamping device located on the carriage, and the locking element is located on the guide bracket, and the fixed thrust bearing from interaction with the sliding movement in the closing direction to the guide bracket, and fixing the clamping device is moved in the direction of the sash is located movement first spline bracket disposed angle regulating hole, a second spline bracket which forms its free end a locking clamping device.

The energy storage device, preferably consisting of a tension spring, is located in the exposed design, which is an advantage, and is fixed at one end near the pivot axis and the guide bracket between the sliding and guide brackets, and the other end is connected to the sliding bracket near the rotary base located on the side of the sash. between the sash and the retractable bracket. In this case, the energy storage device as the sash moves in a parallel-deferred position moves away from the elements of the exposed structure, moving in the direction of the free-use zone, and counteracts the movement of the sash, and the energy storage device acts on the sash in a parallel-deferred position with a certain force accelerating it when moving to the closing position. Having reached the closing position, the sash is held in it by the energy storage device itself or by interacting with it, located in a hidden way and functioning automatically regardless of the accessories that fix the gripping and clamping device.

In order to simplify the design and the connection during installation, the energy storage device or the tension spring are connected via a detachable fastening using the corresponding eyes at the ends with the protruding cams on the sliding and guide brackets, the connection is carried out kinetically by means of a geometric closure.

The energy storage device or tension spring connected by means of a geometrical closure is preferably located on the pull-out bracket, on the side toward the sash and on the guide bracket, on the side towards the cross beam of the frame.

The functional advantage of the power transmission and low production costs are ensured by the fact that the energy storage device, made in the form of a tension spring, is a coil spring, and the screw-wound wire under load and without load is at a remote distance between the sliding and guide brackets, and the tension spring in the closed position of the exposed structure without load is located between the sliding and guide brackets.

The choice of spring steel for energy storage device or tension spring allows you to take high loads due to the extension of the ends, and during this energy is created, which is stored until the tension spring is compressed and controlled release of energy.

Due to the simplicity of connecting the energy storage device with the exposed design and the fact that the energy storage device or the tension spring is a separate structural element, made regardless of the fittings, it can be installed together with the exposed design or, if necessary, subsequent installation on the already mounted fittings.

In the parallel-deflected position of the sash of a window or door, traditional fittings allow you to avoid unwanted slamming due to the presence of special guides and undercuts in the exposed design. Stability in a parallel-deferred position is achieved due to the additional force from the side of the tension spring, and when the sash moves to the parallel-deflected position, the spring is tensioned, and the locking element in the clamping fixing device holds the exposed structure in the parallel-deflected position by means of the tension spring located in a prestressed state, and when the sash moves from a parallel-deflected position in the direction of the frame, the tension spring is opened I and takes a starting position.

Taking into account the requirements for the adjacent closed position of the sash, especially with a large weight of the window or door, the gripping-clamping device consists of locking fittings located on the frame and located on the sash under the action of the spring gripping structure, which is preferably mounted on the lower crossbeam of the window or door and holds the sash against the frame when it reaches the closed position.

The gripping and clamping locking device in a simple and economical design is characterized in that the gripping structure is under the action of force due to the pressure spring located in the housing, which is connected to the shutter kinetically.

Another advantage in terms of functionality, installation and the cost of fittings is the ability to install a gripping and clamping locking device that acts freely, regardless of the fittings, on a window or door. Depending on the size and weight of the window or door, the gripping clamping device may, if necessary, be installed several times in order to increase the starting force.

In FIG. 1-6 show a window or a door located in a fixed frame 1 and consisting of a fixed leaf or a fixed door panel 2, equipped with the same movable leaf 3. Moreover, the movable leaf 3 can from the one indicated in FIG. 1 and FIG. 2 of the closed position is brought into the tilted open position, shifted relative to the fixed frame 1 and the fixed leaf or door panel 2, as can be seen from FIG. 3 and FIG. 4. Additional forms of execution or structural elements of the hardware 10 allow the sash 3 to move relative to the fixed frame 1 and the fixed sash or door panel 2 and move to a fixed parallel-deferred ventilation position or in a parallel-deferred position, and in this case, the sash 3 can the through holes 4 of the fixed frame 1 to move horizontally and to occupy a position in front of a fixed sash or a fixed door panel 2, as can be seen from FIG. . 5 and 6. To ensure these positions of the sash 3 relative to the fixed frame 1 and the fixed sash or door panel 2 between the sash 3 and the fixed frame 1, a special arrangement of fittings is provided, we are talking about the so-called parallel-spaced sliding fittings 10, which is simplified in FIG. . 1-6 only in the form of a control lever 5 on the leaf 3, as well as the upper exposed structure 6 and the lower exposed structure 7 between the wing 3 and the fixed frame 1. A kinematically similar design of the upper exposed structure 6 and the lower exposed structure 7. However, fundamentally different forms of execution of exposed designs. When executing the upper exposed structure 6, it is necessary to ensure the constant entry of its hinged fastenings from the side of the frame into the horizontal sliding guide according to FIG. 7, located on the transverse crossbar of the fixed frame 1, which will ensure the synchronous movement of the extension arms. The lower exposed design 7 is performed in this case in such a way as to reliably hold the weight of the movable leaf 3 during its interaction with the guide rail 9 on the lower transverse crossbar of the fixed frame 1. The main task of the exemplary embodiment is to develop a method for operating the accessories, including the exposed structure 7 , namely, it is a question of the structural and functional design of at least the exposed structure 7 from the side of the closing position. Both from the side of the closing position and from the side of the opening position, the exposed structure 7 comprises a retractable bracket 11 shown in Figures 7-13. Each of the sliding brackets is pivotally mounted on the carriage 13 with the possibility of turning around, in fact, a vertical axial pin 12. Both carriage 13 contain two running rollers 14, freely rotating around essentially vertical axes. Using these running rollers according to FIG. 1-7, they rely on the guide rail 9 of the fixed frame 1, being parallel to it with the possibility of movement. At the other end of the pull-out bracket 1, there is a rotatable base 15 movably connected to a support bracket 16 fixed to the leaf 3, as can be seen from FIG. 8-11. Both travel carriages 13 carrying the extension arms 11 are interconnected by a stable mount by means of a connecting rod 17, as shown in FIG. 10-13 by a dash-dot line. Using this connecting rod 17, the axial pins 12 or the supporting carriages 13 of the exposed structure 7 are constantly held at a constant distance from each other. Also, the rotary bases 15 of both sliding brackets 11 act, at a constant distance from each other, on the leaf 3, namely, the support brackets 16 fixed on it. The leaf 3, both slide carriages 13 with a connecting rod 17 and both sliding brackets 11 form a guiding suspension system of parallelogram type. With this guide system of the suspension, the sash 3 can be moved in the transverse direction relative to the plane of its location and relative to the plane of location of the fixed frame 1, moving between the designated in FIG. 10 with the closing position and indicated in FIG. 7 and FIG. 12 in a parallel-spaced position, with the sash also passing as shown in FIG. 3-4 functional intermediate positions. When shown in FIG. 10, the position of the exposed structure 7 allows direct movement of the sash 3 from the presented FIG. 1 and 2 of the closing position shown in FIG. 3 and FIG. 4, the folding position, while at the corresponding parallel-deflected position of the exposed structure 7 according to FIG. 12, the sash 3 can be moved horizontally to the one shown in FIG. 5 and 6 open position. To ensure reliable holding of the sash 3 in a parallel-deferred position relative to the fixed frame 1 during horizontal movement, a locking mechanism 18 is required to fix the parallel-deflected position of at least both of the sliding arms 11 of the lower exposed structure 7 relative to the fixed frame 1 or relative to moving along its guide running tires 9 of the running carriages 13, which is most clearly shown in FIG. 9 and 12. On the other hand, the actuation of the locking mechanism 18 should automatically unlock the sliding brackets 11 in a parallel-retarded position as soon as the horizontally moving leaf 3 reaches the end point of movement along a sliding path in front of the through hole 4. In this way, the leaf is moved relative to the fixed frame 1 from a parallel-deflected position according to FIG. 12 to the closed position according to FIG. 10. For convenience, the locking mechanism 18 is provided only between the lower sliding bracket 11 from the side of the closing position and the sash 3, as well as the fixed frame 1 or the running carriage 13, although it would be possible to provide such a locking mechanism 18 in the area of both sliding brackets 11 between casement 3 and fixed frame 1. Due to the inevitable interaction of the sliding arms 11 according to the principle of a parallelogram-type suspension system, it is sufficient to locate the triggering locking mechanism 18 in the area of the sliding bracket 11 from the side of the closing position between the sash 3 and the fixed frame 1.

As can be seen from FIG. 8-13, this embodiment involves an additional guide bracket 20 pivotally connected at one end to a lower pull-out bracket 11 (from the closing position side) next to the axial pin 12 of the carriage 13, and freely rotating around the pivot axis 19. The other free end of the guide bracket 20 holds the cam 21, preferably in the form of a pin. The guide bracket 20 contains approximately in the middle, between the pivot axis 19 and the guide cam 21, a locking element 22 extending from top to bottom through the adjustment hole 23 of the locking mechanism 18. The locking mechanism 18 consists of a guide plate located on the carriage 13 (from the closing position side ) and containing a protruding nozzle 24, located towards the vertical bar 25 (from the closing position) of the fixed frame 1. The adjustment hole 24 is made in the form of an angle and is directed the first spline bracket 26 from the protruding nozzle 24 in the direction of expansion 27 of the sash 3, while the second spline bracket 26 forms an angle less than 90 ° from the frame 1 towards the sash 3. The end of the second spline bracket 28 forms a locking device 29 or a locking clamping device for the locking element 22 in a parallel-retracted position according to FIG. 9 and 12. Due to the inclined position of the second spline bracket 28 relative to the first spline bracket 26 or the leaf plane, a kind of blocking protrusion 30 occurs, which prevents the locking element 22 from entering the first spline bracket 26 when the force acts in the vertical direction from the leaf 3 to the frame 1 Thus, it is not allowed to bend the Y-shaped formed by the lower pull-out bracket 11 and the guide bracket 20, the exposed structure 7 in the parallel-set position of the sash 3 relative to the frame 1. Therefore, the remaining retractable brackets of the exposed structures cannot return to their original position, so that the parallel-deflected sash 3 is reliably held by the locking mechanism 18 in its parallel-deflected position. In the range of movement of the guide cam 21 of the guide bracket 20 along a sliding path to the end point, it directly interacts with the fixed thrust bearing 31 on the fixed frame 1 or on the guide rail 9, especially in the lower corner from the side of the closing position.

The joint formed by the sliding bracket 11 and the guide bracket 20 of the exposed structure 7 is driven by a common pivot axis 19, from the moment and during the engagement period of the guide cam 21 of the guide bracket 20, which acts as a control nozzle, and the thrust bearing fixed on the fixed frame 1 31. For these purposes, the thrust bearing 31 on the side of the frame is equipped with an inlet 32, to which the shaped groove 33 is adjacent, bent in the direction of sliding movement to the end point beyond rytiya door 3 relative to the fixed frame 1, as is evident from FIG. 10 and 11.

The ratio of the lengths, the design and the hinge of the sliding bracket 11 and the guide bracket 20 affect the nature of the movement of the locking element 22, located at the end of the carriage 13, from the closed position, and included in the control hole 23.

The nature of the movement depends directly on the movement of the guide cam 21 at the free end of the guide bracket 20, while the latter is in a state of regulating and retaining engagement with the inlet and 32 and the shaped groove 33 by the thrust bearing 31 from the side of the frame. The sash 3 abuts in the closing position to the fixed frame 1, according to FIG. 10, the locking element 22 of the guide bracket 20 is located within the end position of the first spline bracket 26 of the control hole 23, while the guide cam 21 of the guide bracket 20 is located in the area facing the stationary frame 1 of the end of the groove 33 at the thrust bearing 31 with side of the frame, which is also seen from FIG. 10.

Based on the linear dimensions of the extension arm 11 between the axial pin 12 and the pivot base 15, as well as due to the kinematic connection of the directional bracket 20 with the extension arm 11 and the locking mechanism 18 described above, a guided movement of the directional arm 20 is inevitably carried out while moving in parallel the sash 3 from the closing position adjacent to the fixed frame of the sash 3, according to FIG. 8, in a parallel retracted position according to FIG. 9. During this movement, the locking element 22 moves longitudinally inside the control hole 23 from the side of the frame. In this case, the sash 3 moves transversely to the plane of the fixed frame 1, making a parallel-set motion along the path defined by the retractable bracket 11 and the guide bracket 20.

So far, according to FIG. 9 and 12, the locking element 22 of the guide bracket 20 is located in the control hole 23 in the second spline bracket 28 and before the locking protrusion 30, without reaching the locking device 29, the guide bracket 20 is moved relative to the extension bracket 11 so that the guide cam 21 is almost constantly near the end of the shaped groove 33 facing the stationary frame in the thrust bearing 31 from the side of the frame.

The shutter 3 is fixed relative to the fixed frame in a position that reliably holds it from horizontal displacement from the through hole area.

Only if the locking element 22 comes into contact with the locking protrusion 30 located in front of the locking device 29 (Fig. 9), the guide bracket 20 gradually rotates around the pivot axis 19 on the extension arm 11 so that the guide cam 21 of the guide bracket 20 passes from the facing area to the fixed frame 1 of the end of the groove 33 into the area of the inlet 32 of the thrust bearing 31 from the side of the frame and is thus disconnected from the thrust bearing 31 from the side of the frame.

At this moment, the locking element 22 on the guide bracket 20 enters the locking device or the fixing clamping device 29. The locking mechanism 18 engages by geometric locking and rests the sliding bracket 11 on the leaf 3 or on its support bracket 16, preventing reverse rotation around its rotary fundamentals 15. Thus, the parallel-set position of the sash 3 relative to the fixed frame 1 or the running carriage 13 moving on the guide tire 9 is fixed reliably and for a long time.

In this area, one can state an increase in interest in comfort and, consequently, in reliability. To meet growing demands, it is necessary to expand the range of functions of structural components.

For this purpose, an energy storage device 35 is provided for the sash 3 of the window or door interacting with the exposed structure 7. The energy storage device 35 is used to facilitate the operation of a window or door moved from a parallel-deflected position to the closing position of the sash 3 to the frame 1, with the hardware 10 acts as the so-called accessories of the drive rod and transmits the movement of the control handle 5 through the lever transmission of the drive rod and the angle switches to more than one or all sides sash 3. This allows a few located throughout 'the leaf spots to ensure its locking by the locking devices and it parallel-lag or hinged Sliding open position relative to the frame 1 by means of exposed structures 6, 7.

Due to this configuration, no additional machining is required, for example, milled recesses on the elements of the exposed design 7. In addition, this avoids additional faces and angles leading to an increase in production costs.

According to FIG. 8 and 9, an energy storage device 35 is disposed between the guide bracket 20 and the extension bracket 11 in the longitudinal direction.

Due to the compression and counteraction provided by the energy storage device 35 of the sash of the window 3 while moving to the parallel-deflected position from the adjacent closed position, energy is automatically pumped up, which accumulates as the parallel-deflected position is held, which makes it possible to release force when the sash 3 is transferred from a securely held parallel-deflected position in an adjacent closed position to the frame 1 according to FIG. 2 and 10, whereby movement in the closing direction is provided, wherein the energy storage device according to FIG. 8 and 10, unclenches and takes its initial position, not subject to load.

In the embodiment according to the invention, the exposed structure 7 forms a single unit with the energy storage device 35, which makes it possible to adapt to various linear dimensions of the fittings 10. Thus, there is no need for additional installation of the energy storage device 35.

According to FIG. 8-13, the energy storage device 35 consists of a tension spring and is fixed by one end 26 (Fig. 8) near the pivot axis 19 between the extension bracket 11 and the guide bracket 20 on the guide bracket 20, and the other end 37 on the pivot base 15 from the side of the sash between the sash 3 and the retractable bracket 11 is connected to the retractable bracket 11, and as the sash 3 moves in a parallel-deferred position, according to FIG. 9, the energy storage device 35 is removed from the elements of the exposed structure 7 and goes into the free operation zone, counteracting the movement of the sash 3. The energy storage device 35 then acts on the sash 3 in a parallel-deflected position, accelerating its movement to the closed position, when the wing 3 reaches the closing position, according to FIG. 8, she, according to FIG. 10 and 11, is securely held in this position by the energy storage device 35 itself or with the additional assistance of a gripping-clamping device 38 located in a hidden manner and acting automatically, regardless of the fittings.

According to FIG. 9 and 12, the energy storage device or the tension spring 35 are connected via detachable fastening with the corresponding eyes 41 at the ends 36, 37 to the protruding cams 39, 40 located on the extension bracket 11 and the guide bracket 20, the connection is carried out kinetically by means of a geometric closure. In addition, the cam 39 mounted on the sliding arm 11 is mounted on the visible side facing the casement 3, and the cam 40 located on the guide arm is mounted on the side facing the lower cross beam of the frame 1. The sliding arm 11 and the guiding bracket 20 of the exposed structure 7 provide a stable position energy storage devices 35 both during installation and functional plan. By positioning the cams 39, 40, the action of the energy storage device 35 can be set in a simple way. The distance between the cams 39, 40 in the adjacent closed position of the energy storage device according to FIG. 8, determines the action of the tension spring 35. If the distance between the cams 39, 40 is greater than the length of the tension spring 35, then the tension spring 35 is in the prestressed position. Thus, direct interaction is ensured, so that the sash 3 is brought by the tension spring 35 to the closed position, pressing against the frame 1. There are other possible ways of fixing the tension spring 35, such as the version with a spring clip. Not shown, however, a variant is possible in which one or both of the cams 39, 40 are made in the form of a crank and provide the possibility of instrumental adjustment. This adjustment allows you to set the pre-tension of the tension spring 35.

Alternatively, one or more additional cams 40 can be provided located at a great distance from the cam 39 on the guide bracket, which provides a phased increase in prestress.

Preferred is shown in FIG. 9 is a design in which the energy storage device 35, made in the form of a tension spring, is a coil spring, with a screw-wound wire and, accordingly, the range of operation of the energy storage device under load and without load is, according to FIG. 8 and 9, at a remote distance between the sliding bracket 11 and the guide brackets 20, the tension spring 35 in the closed position of the exposed structure 7 without load is located between the sliding brackets 11 and the guide brackets 20.

The energy storage device or the tension spring 35 is preferably made of steel spring wire.

Due to the simplicity of connecting the energy storage device or the tension spring 35 with the exposed structure 7 and the fact that the tension spring 35 is a separate structural element, made independently of the fittings 10, it is possible, if necessary, its subsequent installation on the exposed structure 7.

Compression of the tension spring 35 due to the movement of the leaf in 3 in a parallel-deflected position is achieved due to the action of additional force from the side of the tension spring 35, which securely holds the locking element 22 in the clamping fixing device 29 in the prestressed position, which avoids undesirable collapse of the exposed structure 7, located in parallel position. When the sash 3 is held securely in a parallel-deflected position, to the adjacent closed position, the tension spring 35 is opened, according to FIG. 8 and 10, or occupies a slightly prestressed starting position.

The retained abutment closing position of the sash 3 at the frame 1 and, accordingly, the abutment position of the lower transverse beam of the sash 3, according to FIG. 3 and 4, in the open, tilted position, as well as the provision of a parallel-deflected ventilation position, depending on the version, is possible due to the action of the tension spring 35. Additional structural elements can be used to support the sash 3 in the locked position near the frame 1.

A particularly large weight of the window or door involves the use of additional structural elements, the installation of which subsequently can preferably be carried out several times. Acting independently of the exposed structure 6, 7 or accessories 10, the gripping and clamping fixing device 38 consists of locking fittings 42 located on the frame 1 and located on the leaf 3 of the spring gripping structure 43, which is preferably mounted on the lower crossbeam of the window or door and holds the sash 3 against the frame 1 when it reaches the closed position, as shown in FIG. 10-13.

For the sake of convenience, the gripping structure 43 is under the action of force due to a clamp spring not present in the special housing 44, which is connected to the shutter 45 in a kinetic manner.

When positioning the sash 3 at the frame 1, the shutter 45 is automatically fixed behind the locking fittings 42. For the sake of convenience of execution and connection of the gripping structure 43 when mounted on the housing 44, according to FIG. 10 and 12, a mounting recess 46 is provided for fasteners, for example for a mounting bolt.
