Abstract

A multi-leaf partition has two window, door or other partition leaves 21, 22, each of which is connected to a different frame guide 31, 34 and has a stile 40, 42, 50 that includes an engagement component 50. The engagement components 50 of the two leaves 21, 22 5 interlock when the stiles of the two leaves 21, 22 are opposite each other. The stile of at least one leaf 22 has an external face and connection means 53 to the external face to be connected to a corresponding connection means 54, provided in the detachable profile 90. The detachable profile 90 is configured in a manner that allows their connection and disconnection with the stile 40, 42, 50, when the leaf 22 to which the detachable profile 90 is connected, is connected to the guide 34. The leaf and stile are reinforced to withstand compressive and flexural loads. The strength improvement does not affect the visibility through the glass pane.

Description

Multi-leaf partition with sliding leaves
[0001] The invention refers to sliding leaves of windows, doors and other partitions. In particular, the invention refers to windows, doors or other partitions with two or more leaves. Such sliding partitions close and open openings that are formed in separators, for example walls.
[0002] Figures la to 1c show known layouts of multi-leaf partitions. In these figures the partitions move within the limits of the opening rather than in cavities formed within the separators.
[0003] Figure la presents a partition with two leaves. The leaves move in two parallel guides and overlap at least partially. The leaves have complementary means that engage the two leaves at the position 11, so that the two inline leaves cannot be removed from each other and have areas that overlap, in all possible positions. In Figure la as well as in Figure lb and Figure 1c the arrows indicate the direction in which the leaves can be moved from the position of these Figures.
[0004] Figure lb presents a partition with three leaves. The leaves move in three parallel guides and overlap in twos at least partially. The leaves that slide in adjacent guides have complementary means that engage them at the position 11, so that the two leaves cannot be removed from each other and have areas that overlap in all possible positions. In the configuration shown in the Figure the maximum opening that can be created is approximately equal to the opening between the two edges less the maximum width of the widest leaf.
[0005] Figure 1c presents a partition with four leaves, which move in two parallel guides. The two side leaves overlap with their adjacent leaf which moves in a different guide. The two central leaves move in the same guide and, when they are not locked to each other, they can move away from each other. With this layout, the width of the maximum opening that can be created is approximately half the distance of its edges, if the leaves have equal width. The partition locks only when the two central leaves and the two edge leaves are locked, so that they cannot move. The two centre leaves are locked in the position 14, where the stiles of the two adjacent leaves are in contact and locked to each other. When the partition closes the opening, the stiles of the central leaves are side by side in the position 14 and their overall width is greater than the width covered by the two overlapping stiles in the positions 11.
[0006] Each leaf of known multi-leaf partitions includes a sash, e.g. aluminium, polymer or other, surrounding a flat component, e.g. glass pane. The robustness and stability of the leaf depends on the material and size of the profiles of the sash and in particular the profile or profiles of the stiles. The wider the profiles, the more stable the stile and therefore the leaf. It is clear that a larger sash, particularly in terms of height, requires wider profiles. At the same time, the wider the profiles, the lower the visibility through the glass pane.
[0007] The object of the invention is a stile and a leaf that has the adequate robustness and stability in every size. The object of the invention is also a leaf that allows increased visibility. Another object of the invention is a leaf that facilitates its use in multi-leaf partitions. Another object of the invention is a multi-leaf partition assembled without difficulty. Another object of the invention is also a leaf or a multi-leaf partition, with a configuration that facilitates its maintenance. Another object of the invention is also a method that facilitates assembling of a leaf in place.
[0008] The invention is defined by independent claims.
[0009] Dependent claims define characteristics that offer further advantages to the invention.
[0010] An assembly comprises an elongated stile for a sash of a window, door or other partition leaf and a detachable profile. The stile extends along a longitudinal direction and has a transverse section normal to the longitudinal direction, with two legs, for example Flor T-shaped, of which two legs one has an internal face configured to receive the edge of at least one glass pane and the other of the two legs has an external face with a connection means, which cooperate with a corresponding connection means provided in the detachable profile. The detachable profile has an internal space extending in the longitudinal direction, housing one or more locking element, which move along the longitudinal direction.
[0011] A multi-leaf partition has at least two window, door or other partition leaves, with each of the two leaves configured to be connected to a different guide of a fixed casement. Each leaf has a stile with an engagement clomponent, with the engagement components of the two leaves being engaged with each other when the stiles of the two leaves are located opposite each other. The multi-leaf partition also includes a detachable profile and the stile of at least one leaf has an external face with connection means allowing said stile to connect to a corresponding connection means that is provided in the detachable profile. The cooperating connection means of the stile ad the detachable profile are configured so that they allow connection and disconnection of the detachable profile and the stile when the leaf, to which the detachable profile is connected, is connected to the guide. The detachable profile has an internal space extending in the longitudinal direction and housing a locking element, which moves along the longitudinal direction. The longitudinal direction is the direction along the stile.
[0012] A multi-leaf partition has a first intermediate leaf connected to a first guide and two side leaves, i.e. a second leaf and a third leaf connected to a second guide. The intermediate leaf has two stiles and two engagement components, with each engagement component connected to a different stile of the intermediate leaf. One engagement component of the intermediate leaf is configured to engage with the corresponding engagement component of the second leaf, so as to prevent the detachment of the intermediate leaf from the second leaf and so that the intermediate leaf and the second leaf overlap, so as to remain in an overlapping disposition at least partially. The other engagement component of the intermediate leaf is configured to engage with the corresponding engagement component of a third leaf, in a way that allows the motion of the intermediate leaf and the third leaf away from each other in a non-overlapping disposition. The maximum distance of the intermediate leaf and the second leaf along the guides is when the one engagement component of the intermediate leaf and the corresponding engagement component of the second leaf are engaged. The minimum distance of the intermediate leaf and the third leaf along the guides is when the one engagement component of the intermediate leaf and the corresponding engagement component of the third leaf are engaged. The multi-leaf may also include a detachable profile, preferably connected to a stile of the intermediate leaf. Such a multi-leaf partition could have three leaves or more, with two side leaves and one or more intermediate leaves.
[0013] A method of assembling a window, door or other partition leaf with a plane panel, on a guide of a fixed casement includes (a) placing the leaf on the guide and (b) after placing the leaf on the guide connecting a detachable profile to a stile of the partition leaf, whereby the detachable profile is arranged at a distance laterally from the plane panel.
[0014] The locking element or elements move between two positions: in one the locking elements, protrude from the detachable profile and are engaged either in a fixed element, such as an element of the fixed casement, the ceiling, floor etc., in the other the locking element or elements are retreated within the detachable profile and do not prevent the leaf to slide. A locking element may be pin-like.
[0015] The detachable profile reinforces the stile and consequently the leaf and provides the adequate compressive and flexural strength to the stile, which is subjected to compressive loads, e.g. due to weight, and transverse loads, e.g. wind loads. The improvement in strength does not affect the visibility through the glass pane, since the width of the stile, i.e. the dimension of the stile's cross-section that is parallel to the glass pane, is the minimum possible.
[0016] The detachable profile may have in the internal space a motion transmission component, configured to transmit motion to the locking element. [0017] The locking element may be controlled mechanically. In some examples of the invention, the detachable profile has a control outside its internal space, which is connected to the motion transmission component. In an alternative embodiment the control is a remote control.
[0018] The stile and detachable profile may be connected by any means deemed appropriate. In some examples of the invention, the cooperating connection means of the stile and the detachable profile are configured, so that one is the male means and the other the female means.
[0019] A detachable profile has a length along the longitudinal direction that is equal or almost equal to the length of the stile. Such a configuration hinders the removal of the detachable profile from the sash. Such a detachable profile may or may not include an internal lock.
[0020] Optionally, the detachable profile may have a moving latch. In some examples, the latch, in one position, extends laterally in relation to the longitudinal direction at a distance from the external face of the detachable profile. The latch may be placed in a cassette. The movement of the latch may be synchronised with the locking of the detachable profile lock or may be independent. In some examples the latch is within a cartridge. To enhance stability a stile may have more than one latches.
[0021] In a sliding leaf the detachable profile is preferably arranged at a distance laterally from the glass pane, so that the detachable profile enhances the bending strength of the stile. To this end the detachable profile may have a length approximately equal to the length of the stile.
[0022] The stile may have a profile and an engagement component connected to the profile opposite the detachable profile. If the stile has a fl-shaped transverse section, the engagement component and the detachable profile are in opposite legs of the stile. The stile profile and detachable profile are arranged in opposite sides of the pane of the leaf. [0023] The profile of the leaf frame and detachable profile may be made of polymer, aluminium or other material. If made of metallic material, such as aluminium, they may also have thermal breaks made of polymer, e.g. polyamide. Engagement components may be made of polymer, e.g. polyamide, to achieve thermal break.

[0025] Figure 4 and Figure 5 present a window with three leaves 21, 22, 23 arranged in two guides 31, 34, which are in parallel layout. Each leaf 21, 22, 23 has a glass pane 85, and a sash surrounding it. The sash has stiles and horizontal profiles that connect the stiles to each other. Each stile has a profile 40, which on an internal face has a seat or seats to which the edge of one or more glass panes 85 is applied respectively. The stile also has an engagement component 50 either integral with or connected to its profile 40. In two adjacent leaves that move in different guides with their stiles in overlapping position, their respective engagement components 50 are engaged, so as to allow the relative movement of the engaged leaves only in one direction, i.e. either in a direction that makes the leaves further overlap or in a direction that removes one leaf from the other. When the engagement components 50 are engaged in a "locking configuration", the leaves remain in any position overlapping at least partially. This layout is schematically in Figure 2, which presents the minimum overlap of the two leaves. When the engagement components 50 are engaged in a "release configuration", the leaves can be removed from each other. This layout is shown schematically in Figure 3, which presents the maximum overlap of the two leaves.
[0026] In Figure 5, one side leaf 23, located in the guide 31, is engaged with its adjacent leaf 22 with engagement components 50, in a way that does not allow one leaf to move away from the other. The layout of the engagement components 50 that maintains the overlap of the leaves 22, 23 is schematically presented in Figure 2. With this layout, the leaf 22 is prevented from moving in the direction of the arrow 60 when the side leaf 23 is locked in position and cannot move.
[0027] Furthermore, in Figure 5, the adjacent leaves 21 and 22 located in the guides 34 and 31 respectively, are engaged in a way that does not prevent the removal of one leaf from the other, since each engagement component 50 is arranged in the respective leaf, in a way that does not prevent the removal of the adjacent leaf from it. This engagement is schematically presented in Figure 3.
[0028] In the example of Figure 5, the two end leaves 21, 23 are immobilised in the casing 70 that is fitted along the edges of the opening and therefore the only possible move allowed is that of the middle leaf 22 in the direction of the arrow 61, when the middle leaf 22 is not locked. The locking of the middle leaf 22 is described in a following paragraph.
[0029] In an alternative configuration of the example of, Figure 5 the end leaves 21, 23 are sliding and the limitation of the movement of all three leaves 21, 22, 23 is achieved by limiting the movement of the leaf 22 and the end leaf 23. Limiting the movement of the end leaf 23 is achieved by locking the end leaf 23 in the frame 70. Limiting the movement of the middle leaf 22 is achieved by locking it to the floor 76, as described below.
[0030] When a leaf covers an opening, e.g. an opening provided in a wall, the leaf may be prevented from moving when locked on a fixed surface, e.g. the floor, wall or other. In a multi-leaf partition with three leaves 21, 22, 23 the two end leaves 21, 23 may be either locked with locks, provided for in the stiles, in the frame 70 that is fixed or may be immobilised in the frame 70. The middle leaf 22 may be locked into a body, lying in parallel with the upper or lower guide, e.g. on the floor or/and the ceiling in the case of a door leaf. This respectively applies to multi-leaf partitions with more leaves, e.g. four, five or more leaves, when this form of locking is preferred.
[0031] In the example of Figure 5, the component that locks the middle leaf 22, is an elongated - oblong - detachable profile 90 connected to the stile, opposite to the engagement component 50, so that the detachable profile 90 and the engagement component 50 are placed one on the one side and one on the other side of the glass pane 85. As shown in Figure 5, the stile and the detachable profile 90 are arranged laterally on either side of the of the glass pane 85 and lying parallel thereto. The disposition of the detachable profile 90, glass pane 85 and engagement component 50 is as indicated by the dotted line 55 in Figure 10 and in Figure 14. The locking means that locks the leaf 22 is a pin 91, moving between a position that prevents the leaf 22 from sliding along the guide 34 and a position that allows the leaf 22 to slide. Users can move the pin 91 using a handle 92 that interlocks with the pin 91 through a motion transmission component 94. The pin 91 and the mechanism are located in the detachable profile 90. Optionally, the detachable profile 90 has dimensions, i.e. length and width, that correspond to the dimensions of the stile, so as not to obstruct the view through the leaf 22 more than the stile. At the same time, the dimensions of the of the detachable profile 90, i.e. cross-section and thickness of its wall, may be selected in a manner that ensure the necessary robustness for the sash. The handle 92 exits the detachable profile 90 so that it is accessible to the user. The detachable profile 90 has a body 96 and a cover 95. The detachable profile 90 can be connected to the sash after the sash is placed in the casing 70. The cover 95 allows access to the locking mechanism without disassembling the sash or removing the leaf 22 from the casing 70.
[0032] When the engagement components 50 of two leaves are engaged, each leaf can move only in one direction in relation to the other, depending on the engagement method, see Figure 2 and Figure 3. A multi-leaf partition optionally includes a component that in combination with the locking of the stile via the detachable profile 90 prevents the relative movement of adjacent leaves in both directions. This component may be a latch 98, provided in the detachable profile 90 - see also Figure 18 and Figure 19 - which may prevent the relative movement of adjacent leaves in one direction. In the example of Figure 8, the latch 98 is placed in a cassette 93 and moves simultaneously or separately from the pin 91. One leaf may have one or more latches as required. In the example of Figure 8, there are two latches to ensure the stability of leaves 21, 22, 23 of the multi-leaf partition, even when the end leaves 21, 23 are immobilised. [0033] Figure 14 presents the section of the two stiles of two leaves, in a position where the engagement components 50 are engaged, so as to allow one leaf to move away from the other. The same Figure 14 shows that one of the two stiles has a plug 53 in which the detachable profile 90 is applied through the socket, i.e. cavity 54. Figure 15 presents the components presented in Figure 14 disassembled. As shown in Figure 11, the socket 53 may not extend to the whole height of the stile, to facilitate the assembly of the sash. The detachable profile 90 may cover this discontinuity.
[0034] The stile has a profile 40 with an T-shaped cross-section, with two legs 401, 402. On the inner face of the profile, there is a component 42 - glazing pad - with a Fl-shaped crosssection where the edge of the glass pane 85 or the edges of more glass panes 85 are placed., The engagement component 50 is placed opposite to one leg 402 of the profile and at the edge of the other leg 401. The engagement component 50 has a single cavity 51 hook-like cross-section. One leg of the engagement component 50 enters the cavity 51 of the hook of the engagement component 50 of the adjacent leaf. The permissible relative movement direction of two engaged leaves depends on the orientation of the cavity 51 in relation to the leaf. If a cavity 51 of an engagement component 50 of a leaf faces the glass pane of that leaf, then the leaves cannot be removed from each other. If the cavities 51 are facing opposite the glass pane, then the engagement components 50 do not allow further overlapping of the glass panes 85 of adjacent leaves, as depicted in Figure 14.
[0035] In the leg 402 of the profile 40 opposite the engagement component 50 there is a socket 53 for the detachable profile 90. In the examples of Figure 14, Figure 15, Figure 16 and Figure 17, the detachable profile 90 is of Fl-form with the intermediate leg and an internal space, which can accommodate the locking element 91 and the transmission component 94. The locking element 91 and the transmission component 94 are parts of the internal lock, which locks the stile and prevents the movement of the leaf, where the stile belongs. The detachable profile 90 may or may not include a lock, depending on whether it is used for reinforcement or for reinforcement and locking of the leaf. In one of the two parallel legs of the detachable profile 50 means may be provided for the connection of the detachable profile 90 to the profile 40 of the stile. These means, e.g. screws, which are not shown in the Figure, may be covered with a cover 95. The section of the detachable profile has a width b, extending parallel to the leaf and a height h, extending vertically to it. Width b and height of the cross-section h are shown in an example in Figure 17. Preferably the width is equal to or smaller than the width of the stile so as not to obstruct the view through the glass pane. The height of the cross-section h is chosen depending on the strength required for the stile, which is subjected to transverse flexural loads, e.g. due to wind, or compressive loads, e.g. the same weight when fitted. Figure 17 presents the stile with three detachable profiles of different heights of the cross-section, which do not have an internal lock, as they are applied to the stile of the profile, which does not lock. The length of the detachable profile 90 is equal or almost equal to the length of the stile.
[0036] Figure 20 and Figure 21 show a partition leaf with five leaves and Figure 22 a partition leaf with seven leaves. In the examples shown in these Figures, each side leaf 21, 23 is locked to the casement and the intermediate leaf 22 that is adjacent to a respective side leaf 21, 23 is engaged with the side leaf 21, 23 in a "release configuration", i.e. it may slide away from it. The slidable intermediate leaves 22 have a detachable profile with an internal lock 91, 94 not shown in the Figures and a handle 92. The other intermediate leaf 22 of the five- leaf partition and the other 3 intermediate leaves 22 of the seven-leaf partition are in these examples restricted from movement. These intermediate leaves 22 are engaged with the respective slidable intermediate leaves 22 in a "locking configuration". Figure 20 presents the five-leaf configuration in open condition and Figure 21 presents the same configuration in closed condition. Figure 22 presents the seven- leaf configuration in closed condition. In all examples all leaves are disposed in two guides not shown in the Figures, with each leaf of a pair of adjacent leaves in a different guide.
[0037] A multi-leaf partition has at least two window, door or other partition leaves 21, 22, each of which two leaves is connected to a different frame guide 31, 34 and has a stile 40, 42, 50 that includes an engagement component 50. The engagement components 50 of the two leaves 21, 22 interlock when the stiles of the two leaves 21, 22 are opposite each other. The stile of at least one leaf 22 has an external face and connection means 53 to the external face to be connected to a corresponding connection means 54, provided in the detachable profile 90. The detachable profile 90 is configured in a manner that allows their connection and disconnection with the stile 40, 42, 50, when the leaf 22 to which the detachable profile 90 is connected, is connected to the guide 34. The leaf and stile are reinforced to withstand compressive and flexural loads. The strength improvement does not affect the visibility through the glass pane. In general a multi leaf-profile may have a plurality of leaves sliding on two guides.
