Description

A FRAME FOR AN OPENABLE WINDOW, AND A SYSTEM COMPRISING THE FRAME

The present invention is related to a frame for an openable window, and a system comprising the frame and an openable window. The frame according to the invention is configured for being secured to a building structure and may therefore be denoted static frame. The openable window of the system is pivotably secured to the static frame. Preferably, the openable window is an insulating window.

Insulating windows are cornerstones of modern architecture, serving critical roles in enhancing energy efficiency for both residential and commercial buildings. Despite advances in materials and design, challenges still exist. Traditional openable window systems commonly integrate locking mechanisms directly into a movable frame pivotably connected to the static frame. This approach often restricts design flexibility and may compromise energy efficiency. Moreover, conventional designs often lack the capability to accommodate modern smart-home devices or specialized locking mechanisms.

Historically, locking mechanisms for windows have been developed within the window industry itself. In Europe, for instance, it is common for a locking mechanism to be embedded within a movable sash or frame of the window, while one or more receivers for engaging the locking mechanism when the window is in a closed position, is arranged in a static frame secured to a perimeter of an opening in a building. Traditional locking mechanisms, beyond traditional pin-and-eye locks, operate either within or directly upon the surface of the movable sash or frame of the window.

Previously, the primary function of a window sash or frame was to hold the glazing. However, contemporary designs have expanded the functionalities of sashes or frames of a window to accommodate intricate locking mechanisms, thereby requiring additional space. Such required additional space may be challenging for windows made from wood or plastic, which lack a structural integrity of aluminum and other feasible metals.

Publication WO 02/053863 A1 discloses a control system for a window which comprises a frame and an opening sash with light openings, whereby the opening sash has mechanisms to secure at least one panel-shaped element in the sash's light opening and has a control handle which is connected to mechanisms to secure the opening sash with respect to the frame. The sash comprises at least two sash elements, whereby the first sash element comprises a groove to receive an edge of at least one panel-shaped element, and whereby a second sash element can be mounted on the first sash element to secure at least one panel-shaped element. A latch is positioned on the sash holding the pane.

Publication WO 2005/028793 A1 discloses an outwardly openable window or door structure comprising a frame and a sash provided with a glass pane. The frame and sash are hingedly interconnected and are provided with a locking mechanism comprising a locking tap and a striking plate provided on either of the sash and frame. The locking tap and the striking plate are arranged between an inwardly facing side of the sash (2) and an outwardly facing side of the frame.

CN 110821353 A discloses a glass window wherein a frame of the window is provided with a permanent magnet.

CN 116146050 A discloses a latch positioned in a compartment forming part of a window frame.

Nowadays, requirements for windows go beyond mere functionality and aesthetics. Energy efficiency, sustainability, and carbon footprint reduction are in at least some countries considered to be at least equally important. While wood emerges as a superior material in these considerations, it has its limitations, such as increased material consumption and a shorter lifespan due to its biodegradability.

The invention has for its object to remedy or to reduce at least one of the drawbacks of the prior art, or at least provide a useful alternative to prior art.

The object is achieved through features which are specified in the description below and in the claims that follow.

The invention is defined by the independent patent claim. The dependent claims define advantageous embodiments of the invention.

In a first aspect of the invention, there is provided a frame for an openable window, the frame comprising:

- a first frame portion having a perimeter face defining an outer perimeter of the frame, and an inner face opposite the perimeter face;

- a second frame portion extending from the inner face of the first frame portion, the first frame portion and the second frame portion defining a recess for receiving an openable window, the second frame portion having an outer face for facing the recess, and an inner face opposite the outer face;

- at least one aperture extending through at least one of the first frame portion and the second frame portion;

- a latch arranged in connection with the, or each, aperture and configured for releasably engaging a latch-mating object inserted into the aperture; and

- a latch operating mechanism for controlling the latch between an active position and a passive position.

The latch is accessible from a compartment defined by a profile protruding from at least a portion of the inner face of the second frame portion.

Providing access to the latch from the compartment, may facilitate any maintenance or replacement of the latch. In one embodiment, the profile may comprise a portion constituting at least a portion of the second frame portion.

In a position of use, the frame according to the first aspect of the invention is secured to a building structure by means of at least one of an adhesive and mechanical fastening means and is in such a position immovable or static. Typically, the perimeter face of the first frame portion faces an opening in a wall of a building, or a cladding on an external side of the wall.

In one embodiment, the latch may be a so-called rotary latch. A rotary latch comprises a latching mechanism for receiving a latch-mating object, such as a bolt installed on an opposite part that mates with the latching mechanism, and a latch operating mechanism.

The latch operating mechanism of a latch may comprise an electrically operated actuator. An electrically operated actuator may be controlled from a remote location. Alternatively, or additionally, the latch operating mechanism may be an actuator in the form of a handle configured for manual operation. A handle configured for manual operation does not require any connection to a source of energy.

In one embodiment, at least a portion of the latch is housed within the aperture extending through at least one of the first frame portion and the second frame portion. Arranging at least a portion of the latch within the aperture, at least reduces a space required for housing the latch.

In a position of use of the frame according to the first aspect of the invention, the compartment may form part of a sill of a window, or be arranged in a recess of a wall of a building. To further facilitate accessibility to the latch, it may be advantageous if a portion of the latch protrudes into the compartment so that a portion of the latch is housed within the compartment.

When the frame according to the invention is provided with one or more electrically operated devices, it is an advantage if the compartment comprises an energy source for operating the at least one electrically operated device, or at least a connection to an energy source. An electrically operated device may for example be, but not limited to, a motor, a solenoid, a remotely controlled device for controlling electrically operated devices.

The profile may comprise an openable lid to facilitate access to an inside of the compartment. The lid may in one embodiment be detachable, or it may be hingedly connected to the compartment. In one embodiment, the lid is made from a translucent material. A translucent material allows light to pass through. Thus, by arranging a light source within the compartment a lightening effect of the frame can be achieved.

In a second aspect of the invention there is provided a system comprising the frame according to the first aspect of the invention, and an openable window hingedly connected to the frame, the openable window comprising:

- at least one pane having an inner face for facing an inside of a building, and an outer face opposite the inner face,

- a protruding latch-mating object operatively connected to the at least one pane, and so positioned that the latch-mating object is engaged by the latch of the frame when the window is in a closed position and the latch is in its active position.

The protruding latch-mating object may be directly or indirectly connected to the pane. The protruding latch-mating object may be directly connected to the inner face of a pane of a frameless window, preferably by means of an adhesive. However, a majority of windows comprises a window frame for carrying the at least one pane of a window. In such a window, the protruding latch-mating object may be operatively connected to the at least one pane preferably by connecting the latch-mating object to a portion of the window frame, typically by means of mechanical fasteners, such as for example screws.

The latch-mating object protruding from the window, may typically be in the form of a bolt, or in the form of a bail, to be engaged by the latch of the frame, when the window according to the system is in a closed position.

In one embodiment of the system according to the invention, the window is hingedly connected to the frame by means of electrically operable hinges, wherein driving devices for the electrically driven devices for operating the hinges are arranged in a compartment protruding from at least a portion of the inner face of the second frame portion.

At least a portion of the at least one pane of the window may be configured to overlap the latch-mating object, thereby also the latch of the frame when the window is in a closed position. When the at least one pane is configured as a thermally insulating window, a cold bridge through the latch-mating object is at least reduced.

Any positional indications refer to the positions shown in the figures.

In the figures, the same or corresponding elements are indicated by the same reference numerals. For clarity reasons, some elements may in some of the figures be without reference numerals. Any positional indications refer to the positions in the figures.

A person skilled in the art will understand that the figures are just principle drawings. The relative proportions of individual elements may also be distorted.

In the figures the reference designation S denotes a system according to the invention, wherein the system comprises a frame 1 and an openable window 2, 3 hingedly connected to the frame 1.

The frame 1 comprises a first frame portion 1.1 having a perimeter face defining an outer perimeter surface of the frame 1, and an inner face opposite the perimeter face. The perimeter face of the first frame portion 1.1 may in a position of use typically face an opening in a wall of a building, or an outer cladding of the such a wall, as indicated in fig.9. The frame 1 further comprises a second frame portion 1.2 extending from the inner face of the first frame portion 1.1 to form a substantially L-shaped frame 1. The first frame portion 1.1 and the second frame portion 1.2 define a recess for receiving an openable window. The second frame portion 1.2 has an outer face for facing the recess, and an inner face opposite the outer face. One of the first frame portion 1.1 (see for example fig.

2) and the second frame portion 1.2 (see for example fig.1) is provided with an aperture 4 extending therethrough.

A latch 5 arranged in connection with the aperture 4 is configured for releasably engaging a latch-mating object 6 inserted into the aperture 4. The latch mating object 6 is shown as a bolt in for example figures 1-3, and as a bail in fig.4.

A latch operating mechanism for controlling the latch 5 between an active position and a passive position may be manually operated or electrically operated.

In the figures, the window of the system S comprises a pane 3 carried by a window frame 2. Apart from in fig.2, the window frame 2 is pivotable connected to the frame 1 by means of hinges H as indicated in figures 7 and 8. In fig.2, the window frame 2 is arranged slidably with respect to the frame 1.

In figures 1-4 the pane 3 of the window is clamped to the window frame 2 by means of a list 10 and sealings 11, as will be appreciated by a person skilled in the art.

In fig.1, the latch 5 is arranged within an aperture 4 in the second frame portion 1.2. A latch mating object 6 in the form of a bolt for releasably engaging the latch 5, is secured to, and penetrates a portion of the window frame 2. However, in an alternative embodiment the latch-mating object 6 may for example be a bail as shown for example in fig.4. A latch-mating object 6 penetrating a portion of the window frame represents an increased robustness of the system S. The window frame 2 is pivotably secured to the frame 1 by means of hinges (see fig.8).

In fig.2, the latch 5 is arranged in connection with the first frame portion 1.1.

In fig.3, the pane 3 is in the form of a double glazed unit 3.1 spaced by a spacer 3.2. A grabbing profile 7 for facilitating pivoting the window is arranged on top of an inner portion of the window frame 2.

In fig.4, the latch 5 extends beyond a frame outermost dimension OM, i.e. beyond the inner face of the second frame portion 1.2, wherein the protrusion of the latch 5 represents an extended dimension EOM of the system S. Further, in fig.4, the latch-mating object 6 is in the form of a bail. However, the latch-mating object 6 may have any form adapted for being engaged by the latch 5, such as for example a bolt as shown i.a. in fig.

3.

In fig.5, the system S is provided with a profile P protruding from the inner face of the second frame portion 1.2 and defines a compartment RS. In the embodiment shown, the profile P may typically be made from extruded aluminium or a suitable plastic.

The profile P is provided with a lid L. In the embodiment shown, the lid L is detachable from the profile P, but may alternatively be hingedly connected to the profile P. The material for the lid can be chosen based on specific needs. For instance, if additional components like lighting are added within the compartment RS, a translucent lid L that permits light to pass through, may be utilized. In other scenarios, the lid L may be designed to seamlessly blend with the surrounding surfaces, ensuring an aesthetic integration.

In fig.5, the dimension denoted OL, represents an overlap between the pane 3 (here insulating glazing) and the compartment RS. Since the pane 3 typically has very good thermal insulation properties and the recessed space RS has relatively poor insulation properties, the greater the overlap, the greater the thermal insulation for the system S.

Fig.6 shows an alternative configuration of the profile P wherein the profile constitutes substantially all of the second frame portion 1.2, but still comprises a portion protruding from the second frame portion 1.2 of the frame. Thus, in this alternative configuration, the profile P comprises the second frame portion 1.2.

An appliance A is housed within the compartment RS. The appliance A represents any desirable addition one might want to place within the compartment RS additional to a latch 5 or other than a latch, such as a motor, magnetic control (solenoid), part of a manual release handle, operational wires, speakers, lights, battery, smart device, blind, insect screen or any other feasible equipment, for its usefulness or entertainment. This is possible due to the systematic design of the whole. A profile P can be fitted to more than only the side or sides where a lock is supposed to be placed for almost no extra cost other than the profile itself giving choices of recessed space for many other uses than only the latches 5.

Fig.7 shows an alternative way of connecting the latch-mating object 6, here in the form pf a bolt, to the window frame 2. In the figure, the pane 3 provides a thermal barrier between an outer environment and the compartment RS when the window is in a closed position as shown. A hinge H pivotably connecting the window to the frame 1 is also shown. The hinge H may typically be a side-mounted slide hinge suitable for top-swing windows, a top or bottom-mounted slide hinge for side openings, or a component of a multi-operational system.

In fig.8, the compartment RS houses a motor M that is operatively connected to an axle AX transferring power to an operational arm OA, which is, in turn, linked to a hinge H. Thus, by activating the motor M, the hinge H is activated to open or close the window. The motor is additional to the latch 5 shown in fig.7.

Such a setup, or any analogous mechanism fulfilling the same purpose, could facilitate the automation of opening and closing the window 2,3 of the system S. Coupling this automation with latches 5 that can be both motor-operated and manually accessed in emergencies, offers a system that may be harmonized seamlessly with smart home controls. This synergy enhances user convenience, fortifies security, and optimizes energy efficiency.

In fig.8, the pane 3 only partially overlays the compartment RS.

In fig.9, the system S is integrated into a wooden frame structure arranged externally to an insulated segment of a structure, perfectly overlaying the structural opening. Further, the system S is encapsulated by cladding executed meticulously. The wooden frame structure and the insulated structure include insulation 100, battens and structural timber 101, an external cladding system 102, wind barrier 103, internal cladding 104, and a jamb/sill extension 105.

It should be noted that the profile P defining the compartment RS (see for example 5) is arranged in a recess arranged in the structure.

Fig.10 provides a cross-sectional view of a system S, similar to the depiction in Fig.5. The system S is arranged in connection with a concrete structure 106 that is externally insulated, and it is complemented by an external cladding 102 typically being in the form of panels or a mortar finish.

The components shown in this figure include a core concrete structure 106, insulation 100, a supporting batten 101 for the system S, external cladding, or mortar 102, an internal finish 104, and a jamb/sill extension 105.

It should be noted that the jamb/sill extension 105 may be provided by means of an extended version of the lid L.

Fig.11 is a perspective view of a portion of a system according to the invention, wherein a window is in a closed position, i.e. housed within a recess defined by the first frame portion 1.1 and the second frame portion 1.2.

The frame 1 of the system S is provided with profiles P protruding from the horizontal lower second frame portion 1.2, and from the vertical side portions of the second frame portion 1.2 (only the right side portion shown in fig.11). In one embodiment (not shown), the profile P protrudes also from the horizontal upper second frame portion 1.2.

The compartment RS defined by the profile P protruding from the horizontal lower second frame portion 1.2 houses a latch operating mechanism in the form of a handle OH configured for manual or electric operation. The handle OH is operatively connected to latches 5 (two shown in the horizontal lower compartment RS, and one shown in the vertical, right compartment) by means of a connector C. The connector C is indicated as a rod but may alternatively be provided by means of a wire mechanism. When activating the handle OH, all latches 5 operatively connected to the handle OH are unlocked, thus disengaging from the latch-mating object 6 (not shown in fig.11) and the window can be opened. The handle OH and its connection to the latches may be based on the same principle as used for example in modern vehicles for locking/unlocking doors.

Fig.12 is a perspective view of a portion of another embodiment of the system S according to the invention, wherein the window 2, 3 is in an opened position. As in fig.11, the second frame portion 1.2 is provided with a compartment RS extending horizontally and vertically. In the embodiment shown, the lower, horizontal compartment RS houses a latch 5 and an appliance A, as discussed above in relation to fig.6.

The vertically extending compartment RS shown to the right in fig.12 comprises a motor M operatively connected to a hinge (see H in fig.8) via an axle AX. The motor M may be provided with energy from the appliance A, or from a separate source (not shown) of energy arranged within the compartment RS, or from a distant source of energy, such as from a mains within a building.

The latch-mating object 6 shown in fig.12 is in the form of a bail protruding from an aperture 4 arranged in a portion of the window frame 2. The latch-mating object 6 (the bail) is configured to be inserted through the aperture 4 arranged in the second frame portion 1.2 shown in fig.13 and engage with the latch 5 when the window is closed.

From the above it should be clear that the current invention addresses limitations related to the prior art discussed introductorily, by means of arranging the latch 5 in connection with the frame 1 of the system S, which again allows the window 2, 3 of the system S to be slender and without any movable parts related to a locking mechanism. Embodiments of the invention allows arranging appliances hidden within the system, but with easy access which may be important in an emergency, and for maintenance. The system allows improved energy efficiency.

The system according to the invention allows of a comprehensive system design that is cost-effective, facilitating entering into improved window technology and seamlessly implementing smart solutions for enhanced comfort and energy efficiency.

It should be noted that the above-mentioned embodiments illustrate rather than limit the invention, and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the appended claims. In the claims, any reference signs placed between parentheses shall not be construed as limiting the claim. Use of the verb "comprise" and its conjugations does not exclude the presence of elements or steps other than those stated in a claim. The article "a" or "an" preceding an element does not exclude the presence of a plurality of such elements.
