Definitions

  • the present invention relates to a sliding window mechanism and a sliding window sash or a sliding window frame with this sliding window mechanism as well as a sliding door mechanism and a sliding door sash or a sliding door frame with this sliding door mechanism.
  • sliding windows and doors There are already various types of windows and doors and also a wide variety of designs of sliding windows and sliding doors.
  • the vertical sliding window which is common in America, is just one example.
  • Other types of sliding windows were used in the Renault R4, for example.
  • Other examples where sliding elements are used to make openings in defined areas closable are sliding doors, as they are known from the automotive sector.
  • Various sliding windows and sliding doors, such as sliding doors and folding sliding doors, are also known.
  • sliding windows and sliding doors have had various disadvantages compared to windows and doors with sashes, such as the need for thick frames to accommodate the rollers and window/door mechanisms for opening, closing and locking the window or door. Furthermore, sliding windows and sliding doors usually have a problem with sealing, as high forces cannot usually be applied to the window/door seal and the seal has to be moved over such a seal when a sliding window/door element is moved.
  • a mechanism for a sliding window or a sliding door with a frame and a sliding sash that can be moved horizontally in a sliding direction, wherein the frame has an upper and a lower guide and the sliding sash has an upper and lower guide element, wherein the guides and the guide elements interact and enable the sliding sash to be moved relative to the frame, wherein the mechanism is designed to adjust at least one of the upper guide, the lower guide, the upper guide element and the lower guide element such that the sliding sash is opened or closed at the top and/or bottom perpendicular to an opening direction.
  • sliding window/door sash will be used to refer to “sliding window sash” on the one hand and to “sliding door sash” on the other.
  • At least the upper guide, the lower guide, the upper guide element or the lower guide element can be adjusted so that the sliding window / sliding door can be opened at the top and / or bottom compared to a normal position.
  • the mechanism can adjust one of the guides or one of the guide elements perpendicular to the opening direction.
  • a sliding window / sliding door is provided here that can be tilted at the top and / or bottom.
  • tilt is used for a movement that covers a length of just a few millimeters, a few centimeters at most.
  • the sliding window or sliding door in question does not perform a tilting movement as is known from a tilt-and-turn window where the scissor mechanism allows tilting up to a gap of 10 to 20 cm, but only a few millimeters of movement are achieved, not to allow for a larger exchange of air, but simply to lift a seal on the frame or sash far enough away from a sealing surface to create a small air gap.
  • the basic design can be tilted at the top and/or bottom, with upper tilting being preferred for sliding window/door sashes mounted on the inside, while lower tilting is preferred for sliding window/door sashes mounted on the outside.
  • Sliding windows and sliding doors often use brush seals, which allow a sliding window or sliding door to move while the seal is in place. It is also known to use seals that are pressed against corresponding sealing surfaces when the sliding window or sliding door is in the closed end position.
  • the lower and upper guides as well as the lower and upper guide elements can be designed as desired. It is possible to equip the present invention with sliding elements. It is also possible to use linear plain bearings, axial ball bearings or roller bearings such as recirculating ball bearings instead of sliding elements made of PTFE, for example, in order to enable the components to slide as easily as possible. It is also possible to use guide bearings or air bearings. to allow the window or door sash to slide even more easily.
  • the mechanics of the present invention are rather complex compared to conventional sliding window designs, which is why particular attention should be paid to a particularly good and friction-free bearing.
  • the lower guide comprises a roller track and/or at least one sliding element and the lower guide element comprises a rail
  • the lower guide comprises a rail and the lower guide element comprises at least one sliding element, rollers, a roller track, wherein rollers of the roller track are designed to roll over the rail.
  • an embodiment is specified in which the weight of the window or door is supported from below by a rail that can roll over a roller track. It is also possible for the weight of the window or door to be supported from below by a rail that can slide over the at least one sliding element.
  • either the rail or the rollers, the roller track or at least one sliding element can be adjusted to tilt or adjust the window or door.
  • the window or door is adjusted or tilted on the underside.
  • this is designed to move the rollers, the roller track or the at least one sliding element or the rail parallel to the opening direction when the lower guide or the lower guide element is adjusted.
  • the rail or the rollers, the roller track or the at least one sliding element is adjusted or moved parallel (essentially) perpendicular to a plane of the window/door surface. This parallel displacement can take place in a straight line or along a curve or a circular arc.
  • the rollers, the roller track or the at least one sliding element and the rail run essentially without any particular mutual tilting that exceeds a certain amount of the Tilting that results from an adjustment of only the lower guide or the lower guide element.
  • the mechanism pivots the rollers, the roller conveyor, the at least one sliding element or the rail about an axis that runs parallel to the opening direction. This is to be carried out in such a way that pivoting causes a shift in the point at which the rollers, the roller conveyor, the at least one sliding element and the rail touch each other or at which the rollers roll over the rail or the at least one sliding element slides over the rail and causes a movement of the sash with respect to the frame that is at least partially essentially perpendicular to a window/door surface and thus also perpendicular to the opening direction.
  • the pivot axis of the roller conveyor or the rail does not coincide with the point at which the rollers run on the rail or the at least one sliding element slides on the rail.
  • the pivot point of the rail and/or the rollers, the roller conveyor or the at least one sliding element is preferably below the contact area of the rollers or the sliding element with the rail, so that a pivot area preferably has two end positions that are in a stable position. It can also be provided that only a closed position of the rail or the roller rail or of the at least one sliding element assumes a stable position under gravity conditions, whereby it can be ensured that even without the introduction of force by an operating element, the sliding sash is automatically pressed against a window/door seal.
  • an upper guide comprises rollers, a roller track or at least one sliding element and the upper guide element comprises a rail. It is also possible for the upper guide to comprise a Rail and the upper guide element comprises rollers, a roller track or at least one sliding element.
  • the mechanism is designed to pivot the rollers, the roller track, the at least one sliding element or the rail about an axis that runs parallel to the opening direction.
  • an embodiment of the invention is proposed in which an upper part of the sliding sash can be adjusted analogously to the above embodiments of the lower sliding sash in order to extend or close an upper part of the sliding sash or to tilt or tilt the sliding sash at an upper edge. This embodiment is also aimed at achieving only a small degree of tilting.
  • the focus is on sealing the sliding sash perpendicular to an opening direction.
  • the embodiment relates to sealing an upper edge of the sliding sash.
  • the mechanism can be used to improve sealing on at least part of the sliding sash or to reduce friction between a seal and a sealing surface when the sliding sash is moved by lifting the seal from the seal or at least significantly reducing the contact pressure acting on the seal. Even if the main focus is on tilting the sliding sash, it is also intended to move the entire sliding sash in parallel and to press seals against sealing surfaces or lift them off sealing surfaces.
  • the upper rail and the rollers or the roller rail or the at least one sliding element should be designed in such a way that they are able to compensate for movement of a lower rail, the lower rollers, the roller rail or at least one lower sliding element.
  • a roller arrangement is provided in which rollers with vertical axes run in a U-shaped rail and the dimensions of the rails allow the rollers to tilt slightly in the rail or allow at least a small vertical movement of the rail in relation to the rollers or the roller rail.
  • a sliding element arrangement can also be used in which the at least one sliding element and the rail have a cross-sectional profile that allows mutual pivoting in a longitudinal axis.
  • this can be achieved by a contact surface that forms part of a circular cylinder shell, which enables sliding in the longitudinal direction as well as in the circumferential direction.
  • the contact surface should be as large as possible in order to ensure a low surface load on the sliding elements and thus achieving low wear.
  • the upper guide comprises rollers, a roller track or at least one sliding element and the upper guide element comprises a rail, or the upper guide comprises a rail and the upper guide element comprises rollers, a roller track or at least one sliding element.
  • the mechanism adjusts the rollers, the roller track or the rail so that the axis of the rollers, the roller track or the rail are moved parallel when adjusted.
  • the mechanism can adjust the sliding element or the rail so that the contact surface of the slide track and the rail are moved parallel when adjusted. This can be achieved using a parallelogram guide or using several actuators that adjust the individual rollers perpendicular to a surface of the window/door sash.
  • the mechanism is set up to adjust the lower guide and/or the lower guide element by tilting the guide and/or the lower guide element and is also set up to adjust the upper guide and/or the upper guide element by a parallel displacement in a horizontal direction.
  • the horizontal direction of the adjustment of the upper guide and/or the upper guide element occurs perpendicular or at least essentially perpendicular to a surface of the sliding sash.
  • this is characterized in that by adjusting the upper guide or the upper guide element and the lower guide or the lower guide element, at least one window/door frame seal on a sliding window/door frame against a sliding window/door sash and/or a window/door sash seal on the sliding window/door sash is pressed against the sliding window/door frame, or is lifted off from it, in a direction that is horizontal and perpendicular to the opening direction.
  • This is a combination of movements on the upper window/door sash side and the lower window/door sash side, which serves to seal the entire window/door sash in a closed position.
  • Adjustable seals or seals that allow a window/door sash to be opened or closed with the seal in place can be dispensed with.
  • the mechanism allows a joint adjustment of the upper guide or the upper guide element and the lower guide or the lower guide element with a single operating element.
  • the sliding window/door sash can be opened by a single operation of a control element at the top and bottom. This allows the sliding window/door sash to be lifted off seals that seal perpendicular to an opening direction and to be opened or closed without resistance.
  • the mechanism allows separate adjustment of the upper guide or the upper guide element and the lower guide or the lower guide element.
  • only part of the sliding window/door sash can be tilted by operating a control element that is part of the mechanism. Even if the tilting is less, as is known from tilt-and-turn windows and tilt-and-turn doors, and a viewing gap does not necessarily have to be created when the window/door sash is tilted at the top or bottom, the tilting allows the seals at the top or bottom of the window/door sash to lift off the corresponding sealing surfaces and thus allow air to exchange when the window or door is tilted.
  • transverse openings can be provided in the roller rail, the sliding elements or the rail to enable greater air exchange. It can also be planned to design the fold in such a way that it can be folded on one or both sides tilted sliding sash allows for increased air flow.
  • the mechanism comprises at least one operating element and at least one actuator element, wherein the operating element is connected to the at least one actuator element by at least one operative connection.
  • the at least one actuator element is designed to mechanically adjust at least one of the upper guide, the lower guide, the upper guide element and the lower guide element.
  • the operating element can be designed as a sliding or pivoting lever, the operative connection as a rod and the actuator element as a lever that adjusts a guide or a guide element.
  • control element the active connection and at least one actuator element are connected to one another by a mechanical connection, an electrical connection or a hydraulic connection.
  • the actuator element is designed to adjust at least one of the upper guide, the lower guide, the upper guide element and the lower guide element in order to tilt, extend or slide the sliding window/door sash.
  • an electric drive for example, for opening or closing the window/door sash into the frame.
  • a control element can comprise buttons that enable opening by simply pressing a button.
  • the mechanism comprises sensors to prevent objects or body parts from becoming trapped.
  • the upper guide is designed as rollers, as a roller rail or with at least one sliding element and the upper guide element as a rail or U-rail, or the upper guide is designed as a rail or U-rail and the upper guide element is implemented with rollers, a roller rail or at least one sliding element.
  • the axes of the rollers or a roller rail and the rail or U-rail are arranged at an angle to the window surface.
  • the rail and the rollers enable a mutual displacement.
  • the angle of inclination allows an upper side of the sliding window/door sash to be opened or closed when the sliding window/door sash is raised or lowered by adjusting the lower guide and/or the lower guide element.
  • the upper rail and the rollers or at least one sliding element force the sash to move up or down in an oblique direction, which ensures that the upper part of the window or door is raised during an upward movement and closed during a downward movement.
  • This design has the advantage that only a separate mechanism needs to be provided at the bottom, which enables the window/door sash to be opened or closed, but above all raised and lowered. This allows for simpler mechanics, since all movable components - especially in windows - can be integrated in the lower part of the sash or frame.

It is also possible to use two mechanisms with which the guides on the one hand and the guide elements on the other can be adjusted. Such an embodiment is aimed at further increasing the degree of ventilation when the window or door is open. It is also possible to design a mechanism in a split manner in order to adjust only an upper guide element or an upper guide on the one hand or to adjust only a lower guide element or a lower guide on the other.

  • the push rod moves perpendicular to the image plane in the view.
  • the roller axes are attached to deflection levers 84, each with a roller, so that a displacement of the push rod leads to a tilting of the lever and a displacement of the rollers in the image plane.
  • the displacement of the roller axes also causes a displacement of the U-shaped rail 42 and thus an adjustment or setting up of the sliding window/door wing 4 relative to the sliding window/door frame 6.
  • Lines 7-7 are drawn, which represent cutting lines along which the window or door for the representation of the Figures 7A and 7B are cut.
  • rollers are used that run in a U-rail.
  • the upper rollers are only used to guide the upper part of the sliding window/door sash laterally.
  • There is almost no force on the rollers here because the window is essentially vertical or is only slightly tilted.
  • the rollers of the figure can also be replaced with PTFE cylinders or appropriately shaped sliding blocks or sliding elements that run in the U-rail. It is also conceivable to use only a single rail and to use n-shaped sliding blocks that can support a single rail from both sides.
  • Figures 7A and 7B each show a sectional view through the mechanism for extending the upper guide by adjusting the rollers on the upper sliding window/door frame 6.
  • the sliding window/door sash 4 is shown in a raised position.
  • the deflection lever 86 with the roller 48 is extended and holds the Sliding window/door wing 4 away from the sliding window/door frame 6.
  • the roller 48 only guides the sliding window/door wing 4 and is not able to bear the weight of the sliding window/door wing 4.
  • the push rod 80 is shifted to the right and, by pivoting the lever 86, the roller 48 is pressed closer to the frame 6 until the seal (not shown) rests against an associated sealing surface and seals the window or door.

  • Figure 9 represents a further possibility for adjusting a lower guide 24, which is designed here as a rail 40, arranged in the frame 6 of a sliding window or a sliding door.
  • the rail 40 works together with a roller rail 44 which is embedded in the sliding window/door wing 4.
  • the roller rail 44 serves as a lower guide element 20.
  • This design requires a larger frame of the sliding window/door wing 4 in order to be able to accommodate at least the diameter of the guide rollers 46.
  • An advantage of the design of Figure 9 is that all guide rollers 46 run permanently on the rail 40 and so no running up and down of one end of the rail 40 on a guide roller 46 occurs, which could hinder a sliding movement.
  • the execution of the Figure 9 allows, provided that the upper guide elements in the sliding window/door wing 4 are also designed as rollers, an opening or closing movement that can be completely smooth.
  • the design of the Figure 9 also allows the number of guide rollers 44 to be reduced significantly, since there is no running of rollers onto or off a rail end.
  • Figure 10 provides another possibility for adjusting a lower guide 24.
  • the lower guide 24, here as in Figure 3A designed as a roller rail 44 is embedded in the lower frame 6 of the sliding window or sliding door.
  • the rail 40 which is attached to the sliding window/door wing 4 as a lower guide element, is wider and essentially flat.

  • an operating element 10 is designed as an operating lever 12 (where a push rod is not shown).
  • the operating lever 12 is connected to a parallel four-bar mechanism that enables a parallel displacement of the roller rail 44 on a circular arc.
  • the parallel displacement can be designed symmetrically here, so that the mechanism and the sliding window/door wing 4 assume a stable position under the influence of gravity both in the closed position and in an open position, in which there is no load on the adjustment mechanism.
  • Figures 11A and 11B show a possibility to extend or close the upper part of a window or door wing without the need for a separate mechanism.
  • the upper guide 26 is designed as a series of rollers 48 which run in an upper guide element 22 which is designed as a U-rail.
  • the rollers are designed as inclined rollers 52 and which run in an inclined rail 50.
  • the inclined rollers 52 run on an upper edge of the inclined rail 50. If the window or door sash 4 is raised, the inclined rollers move further into the inclined rail 50 and press the window or door sash 4 away from the window or door frame 6.
  • the window or door sash 4 can be raised in order to expose the upper part of the window or door sash 4.
