Abstract

The invention relates to an arrangement (100) for reversible glazing-in of an open space, with at least one covering unit (102) carried on roller elements (103, 104, 105) between guide rails (106, 107). When in a predetermined position, each covering unit (102) is able to perform a pivoting motion while being arrested from horizontal transport by a parking station (112, 113). One or several of the covering units (102) comprise(s) a third roller element (105), wherein all three roller elements (103, 104, 105) comprise spherical shapes or truncated spherical shapes. The guide rails (106, 107) comprise substantially tubular profiles (114) having inner surfaces which partially enclose the three roller elements (103, 104, 105) during the horizontal transport and at least the first (103) and the second (104) roller element during the pivoting motion. The first and/or second hinge device comprises a recess and/or a protuberance (116, 117), arranged for receiving or being inserted in, and for cooperating with at least one protuberance and/or at least one recess (118, 119) of the parking station during the pivoting motion. The invention is implemented in connection with open spaces such as balconies, terraces, patios and the like.

Description

Position in the upper and lower rails by two means arranged substantially directly above each other, after which the unit is parked near a remote unit.

WO 97/11247 also describes an apparatus for glazing an open space, such as balconies. The apparatus comprises a number of rectangular and square units with glass or plastic panes which are intended to cooperate to cover the open space, the units being able to be brought to a parking position in which the previously glazed space is open and the units are intended to move along an upper and a lower longitudinal rail. The described apparatus is stated to comprise that each unit is provided with upper and lower means for co-operation with the two rails, the means being arranged so that their positions form a triangle. Each means is arranged at a corner portion of the unit and has a first part attached to the corner portion of the unit, and a second part comprising a rotatable wheel mounted on a substantially horizontal shaft. The second part of the means is rotatable relative to the first part. Each unit is said to be designed to be able to pass a 90 ° corner which forms a connecting binding area for a first rail and a second rail which forms a 90 ° angle to the first rail. It is further stated that each unit from the position it has when it moves along the rails can be swung out so that the unit suspended in an upper and a lower means can be moved to an end position, where each unit can be parked close to each other on a minimal surface.

WO 97/1 1247 also states that each unit advantageously comprises two means in its lower part, one at each corner of the unit, and that a portion of the lower longitudinal rail is cut off and replaced by an openable and closable door through which one the lower means can be detached from the rail and the unit consequently swung out while the unit is suspended in the upper means and in the remaining lower means.

Furthermore, the patent specification EP 0 685 024 B1 describes a pivotable and slidable glazing structure which comprises one or more window units suspended between upper and lower guide rails for horizontal sliding movement along these, each window unit having a front edge and a rear edge and is adapted to at a predetermined position for each window unit along said guide rails, perform a pivoting movement about its front edge by means of a hinge arrangement supported on the window unit and arranged in the vicinity of the front edge, the structure further comprising means for locking the hinge arrangement against further sliding movement at said predetermined position before and during the rotational movement.

According to EP 0 685 024 B1, the means for locking the hinge arrangement at said predetermined position comprises a means for displacing a portion of the window unit inwards to cause at least a part of the hinge arrangement to be inserted into and held in a receiving element mounted on one of said guide rails. .

U.S. Pat. No. 4,5 73,286 discloses a device for suspending a releasable panel or similar load which comprises at least one roller element attached to the movable panel by means of a connecting part. The roller element is stated to comprise two rollers in cooperation with roller surfaces of a tubular guide rail, which may have rectilinear portions and curved portions and curved portions, the roller surfaces of the guide rail being located in opposite directions on each side of the connecting part at an oblique angle relative to the connecting part. The problems of the two roller surfaces and the two rollers are stated to be adapted to each other in order to prevent a movement of the roller element in a plane transverse to the tubular guide rail.

The prior art arrangements for reversible covering of open spaces with window units, panels, or other cover units may appear to be associated with certain problems.

Arrangements where the units can only move in the direction of the guide rails and cannot be opened by turning inwards show limited fl flexibility in the event that it is desired to open up the whole or cover only a part of the relevant space. In order to be able to open up, for example, a glazed balcony, arrangements with slidable but non-pivotable cover units require either that there is space available for sliding away the units in a row one after the other in the direction of the guide rails, or that par your pairs of guide rails are arranged parallel to each other so that cover units on different pairs of guide rails can pass past each other when covering or opening the balcony. As has been seen above, there are previously known arrangements in which the units can both slide on roller means in the direction of the guide rails and be opened by pivoting inwards orlaning one edge thereof by means of hinge arrangements attached to upper and lower roller means supporting the unit. during the swing movement. Such arrangements generally require a complicated opening procedure in which a hatch or the like is removed to allow one or more of the roller means in the other edge of the unit to be detached from the guide rail or rails by a recess. Furthermore, it may be perceived as less appealing that one or your rolling means accompanies the cover unit when opening, as the flared cover unit thereby becomes considerably more visible and can disturb the aesthetic impression of a beautiful view, wall, or the like.

Previously known arrangements with cover units which in open / swung-out position can be pushed further along the guide rails can entail a risk that cover units collide in such a way that, for example, a window pane breaks.

When mounting arrangements with roller means of conventional type, a careful fitting of the guide rails is required so that the cover units can be slid back and forth on the guide rails without jerking or jerky movement, especially when the guide rails comprise curved portions past which the cover units can pass.

Conventional arrangements have different cylindrical roller means and generally allow the roller means to move to some extent in the transverse direction of the guide rails, i.e. in the axial direction of the cylindrical shapes. Such a gap is undesirable as it can cause problems with rattling or rattling when the units are pushed along the guide rails or in the event of strong gusts of wind.

Furthermore, the previously known arrangements for reversible covering have clumsy hinge devices and rolling means, which means that covering units that are parked in the swung-out position need a large space and can be perceived as disturbing.

Disclosure of the Invention Thus, a first object of the present invention is to provide an arrangement for reversible covering, which solves the problems of play in the suspension of the cover units in the guide rails and clumsy hinge devices and roller means, and which ensures that cover units of the arrangement can be pushed along, and when parking, swivel out from, the guide rails in a safe, even and quiet manner.

This first object of the invention is achieved, in accordance with claim 1, in that the arrangement comprises one or more cover units mounted on roller means between upper and lower guide rails for substantially horizontal movement along said guide rails. Each cover unit then has a first edge and a second edge, and comprises in the vicinity of the first edge a first hinge device connected to a first roller member supported by the upper guide rail and a second hinge device connected to a second roller member supported by the lower guide rail. In this way, each cover unit, when in a predetermined position along said guide rails, can perform a pivoting movement around its first edge while the cover unit is locked from further horizontal movement along the guide rails by a parking station acting on at least one of said hinge devices. Furthermore, one or some of the cover units also comprises a third roller means.

According to the invention, the first, second and third roller means comprise spheres or truncated spheres, while both the upper and lower guide rails comprise substantially tubular profiles with inner surfaces, which at the horizontal surface partially enclose the spheres or the truncated spheres, the second roller means and the third roller means. .

During the pivoting movement, the inner surfaces partially enclose the spherical shapes or the truncated spherical shapes of at least the first and the second roller member. Furthermore, the first and / or second hinge device comprises a recess and the parking station at least one projecting member, which is arranged to enter and cooperate with the recess during the pivoting movement.

A second object of the present invention is to provide an arrangement for reversible covering where the covering units parked in the swung-out state are as discreet as possible.

This second object of the invention is achieved, according to claim 2, in that the third roller means is mounted on a locking unit, arranged to lock a locking member of the cover unit at the horizontal surface and to predetermined position releasing the locking member and enabling the pivoting movement, the inner surfaces of the tubular profile of either the upper or lower guide rail partially enclosing the spherical shape or the truncated spherical shape of the third rolling member both during the pivoting movement and at the horizontal lining.

Additional objects of the invention will be apparent from the following description, while the features which make it possible to achieve these objects will be apparent from the appended subordinate claims.

Detailed Description of Preferred Embodiments In the following, a preferred embodiment and a number of alternative embodiments of the arrangement according to the invention will be described with reference to the appended Figures 1-8.

The inventive arrangement 100; 200, 200 '; 400; 500 is intended for reversible covering of an open space 101; 201, 201 '; 401; 501, which is advantageously a balcony, a terrace or a patio, and in the described embodiment a balcony.

The arrangement comprises one or more cover units 102; 202a, 202b, 202c, 202d, 202a ", 202b", 202c °, 202d '; 402, 502 supported on roller means 103, 104, 105; 203a ', 203b', 203c °, 203d ', 205a', 205b °, 205c 'between upper 106; 206 'and lower 107 guide rails for substantially horizontal for fl surface along said guide rails.

Each cover unit 102; 202a-d, 202a'-di °; 402, 502 have a first edge 108; 208b ° and a second edge 109, and includes in the vicinity of the first edge 108; 208b 'a first hinge device 110; 210a ', 210b °, 210c °, 210d ° connected to a first roller means 103; 10 15 20 25 30 513 307 8 203a ° -d ° supported by the upper guide rail 106; 206 'and a second hinge device 111 connected to a second roller member 104 supported by the lower guide rail 107.

Each cover unit 102; 202a-d, 202a'-d 'may, when in a predetermined position along the guide rails 106, 107; 206 ', perform a pivotal movement about its first edge 108; 208b ”while the cover unit 102; 202b 'is locked ytterligare from further horizontal dry fl surface along the guide rails 106, 107; 206 'of a parking station 112, 113; 212 'acting on at least one of the hinge devices 110, 111; 210a'-b ', 210d'.

One or more of the cover units 102; 202a "-c" of the arrangement also includes a third roller member 105; 205a'-c '.

According to the invention, the first, second and third roller means 103, 104, 105; 203a ° -d'i, 205a'-c 'spherons or truncated spherical shapes, while both the upper 106; 206 'and the lower guide rail 107 comprise substantially tubular profiles 11 14, 1 1 5; 214 'with inner surfaces, which at the horizontal surface partially enclose the spheres or the truncated spheres of the first, second and third roller means 103, 104, 105; 203a'-d °, 205a'-c '. It is preferred that at least 60% of a first imaginary circular circumference of the spherical shapes or the truncated spherical shape of the spheres 103-105; 203a'-d ', 205a'-c') are enclosed by a second imaginary circumference of the tubular profiles 114, 115; 214 'inner surface. In the described embodiment, the degree of enclosure is about 75%. Thanks to the tight enclosure of the inner surfaces around the spheres or the truncated spheres, it is ensured that the cover units can be easily slid along the guide rails in a safe, even and quiet manner.

In the pivoting movement, the inner surfaces of the profiles partially enclose the spherical shapes or the truncated spherical shapes of at least the first 103, 203a'-d ° and the second 104 roller means, the first 110; 210a "-d 'and / or other 111 hinge device includes a recess 116, 117; 216b 'while the parking station 112, 113; 212 'includes at least one protruding member 118, 119; 218 b ', which is arranged to step into and co-operate with the deepening 1 16, 1 17 during the pivoting movement; 216b '. The interaction which, according to the invention, is achieved between the projecting member and the recess 10 15 20 25 30 513 307 9 ensures that the cover units can be swung out during parking in a safe, even and quiet manner, without the risk of, for example, a window pane breaking. In the one on fi g. 1 shows the embodiment of the arrangement according to the invention, the parking station 11, 1, 13 acts on both the first 1 10 and the second 1 1 1 hinge device. However, it is also possible to imagine the embodiments where the parking station only acts on the first or on the second hinge device. By parking station is meant the entire area where the cover units are intended to be parked in the swung-out position. Because the ear devices are designed with a recess, they become very compact and light, which is an advantage from the point of view of appearance and when the cover units are to be moved along the guide rails.

In the preferred embodiment of the arrangement according to the invention, the third roller means is 105; 205b ° mounted on a locking unit 120; 220b °, 220c °. The locking unit is then arranged to lock a locking member 121 at the horizontal surface; 221c 'of the cover unit 102; 202c 'and to release the locking member 221b' in the predetermined position and enable the pivoting movement, the tubular profile 14; 2 14 'inner surfaces of either the upper 106; 206 'or the lower guide rail partially encloses the spherical shape or the truncated spherical shape of the third roller member 105; 205b'-c 'both during the pivoting movement and during the horizontal movement. This means that the third roller means 105; The preferred embodiments of the 205b '-c ° are retained in the tubular profile regardless of the position of the cover unit, or of whether the cover unit runs along or is swung out from the guide rails. Since the locking unit and the third roller means do not follow the cover unit when swung out, the cover units become very discreet even in the swung-out state.

One can also imagine embodiments of the arrangement according to the invention without a locking unit and where the third roller member follows the pivoting movement of the cover unit (not shown in the ur gures). Such an embodiment requires that the degree of enclosure of the guide rail in question be reduced locally with a recess or the like so that the third roller member can be detached from the guide rail when the cover unit is in the predetermined position. Such embodiments do not provide all of the above aesthetic benefits, but may be economically advantageous. In the preferred embodiment of the arrangement according to the invention there is furthermore a locking station 122; 222 'arranged at the upper 106; 206 'and / or the lower guide rail, in the described embodiment only at the upper guide rail. The locking station is arranged to actuate the locking unit 220b 'to release the locking member 22lb' and allow the pivoting movement when the cover unit 202b 'is in the predetermined position and to lock the locking member 121; 22lc ° during the horizontal movement of the cover unit 102; 202c 'from and to the predetermined position. However, one can also imagine less advantageous embodiments where locking or unlocking takes place in another way, for example manually by pressing a button or the like.

In the preferred embodiment of the arrangement according to the invention, the locking unit comprises 120; 220a 'of one or more cover units a coupling member 123; 223a ', 223V, which is arranged for coupling to a coupling portion 124, 125 of the first 110; 20b ', 210c' or other 211 hinge device of another cover unit below the horizontal for the surface of the parking station 112, 113; 212 'to the locking station 122; 222 'and for disconnection from said first or second hinge device at a further horizontal for-pass past said locking station 122; 222 '. This feature guarantees that a third roller means with its locking unit is always in the correct position in order to be able to lock a locking member of a cover unit which is closed by pivoting movement and then subsequently moved substantially horizontally along the guide rails. Of course, embodiments are also conceivable in which coupling instead, or even, takes place between a coupling member and a second hinge device which runs along the lower guide rail.

Furthermore, it is of course not absolutely necessary that the locking unit which is located at the end has a coupling member, since there is no additional hinge device to be coupled to. Analogous to this, a hinge device which is extremely difficult to connect does not need to have a coupling portion either, since there is no coupling means with which to connect the outermost hinge device.

In an alternative, particularly advantageous embodiment of the invention, the arrangement comprises a plurality of cover units, of which a first cover unit 202d 'is arranged to cooperate with a child-resistant locking device 226'. The first cover unit 202d 'is then permanently arranged in the predetermined position in order to be able to perform only pivoting movement. In the described embodiment, the child-resistant locking device can only be actuated by means of a special key (not shown) intended to fit in a keyhole of the locking device. Since none of the other cover units can be moved horizontally or swung out before the first cover unit 202d 'has been unlocked via the locking device 226' and swung out, this embodiment ensures that small children cannot start opening the covered, open surface 201 without an adult providing the key.

In another advantageous embodiment of the arrangement according to the invention, the upper and lower guide rails are curved at one or fl your places at an angle in the horizontal plane to form one or fl your corners 427a, 427b; 527a, 527b, 527c, 527d past which one or more of the cover units 402; 502a, 502b may pass below the substantially horizontal surface. This is made possible by all rolling means being rotatably arranged in relation to their respective covering units and by the enclosure of the guide rails in the corner being adapted so that all moving parts move freely but without the rolling means being inadvertently detached. Such an adjustment must be made separately from case to case depending on the routing of the guide rails and the geometric design of the arrangement in question in general. Because the cover units can pass through the corner, the inventive arrangement in this embodiment obtains great flexibility, and can be used for open spaces with a number of different shapes.

In another advantageous embodiment of the arrangement according to the invention, the parking station 412 is; 512 arranged in the vicinity of a corner 428; 528 of the open space 401; 501. In this embodiment, the cover units are thus parked in a place where they are in the road as little as possible, and the open space can be used in the best possible way.

Figures 6 and 7 illustrate a preferred construction of a first hinge device 110 with associated first roller means 103 for use in the arrangement according to the invention, wherein the roller means 103 is rotatably arranged on a curved shaft 129 by means of a ball bearing 130. Furthermore, a relation relative to the shaft is included. rotatably mounted fastening link 131 intended to be fastened to a cover unit (not shown in fi g. 6-7). The illustrated construction can also be used for a second hinge device with a second roller means. Within the framework of 10 15 20 25 30 513 v30? In the invention, it is of course conceivable with many other design solutions than those shown in Figures 6 and 7.

Figure 8 illustrates the parts included in a preferred construction of a locking unit 120 with its associated third roller member 105 for use in the arrangement according to the invention, the third roller member 105 also being rotatably mounted by means of a ball bearing 132 on a curved shaft 133. Furthermore, the coupling member 123 is shown which is intended to be coupled to a coupling portion of a hinge device (not shown) belonging to another cover unit (not shown) and a locking member 121, in the form of a latch, which is intended to be fixedly mounted on the associated cover unit (not shown) to be able to be locked in and detached from the locking unit 120.

The preferred construction also includes a spring-loaded opening tongue 134 on which the previously discussed locking station 122 is intended to operate with an elevation 135, shown at fi g. 1. When a cover unit is in the predetermined position, the ridge 135 will act on the opening tongue 134 so that the locking member 121 is released from the locking unit 120 and the cover unit 102 can be swung out for parking.

The above-mentioned coupling member 123 is designed to be able to be locked in a coupling portion (similar to those denoted by 124, 125 of, for example, fi g. 1) of an adjacent hinge device (not shown).

The coupling portion 124 is in the preferred construction a recess in the hinge device 10 with dimensions which are adapted to allow insertion of a coupling member on an adjacent hinge device of a cover unit which is closed, and to frictionally hold the coupling member of an adjacent locking unit with a force adapted to allow the locked coupling member to be released when a cover unit during horizontal movement in the direction away from the parking station along the guide rails arrives at the locking station and passes it. This is evident from fi g. 3 through the cover unit 202b 'which is in swing movement, and the cover unit 2020' which is passing the locking station 222 '. Many other design solutions that enable interconnection are, however, conceivable within the scope of the invention. The present invention is in no way to be construed as limited to what has been described above in connection with the various embodiments, or to what is shown in the accompanying drawings, but the scope of the invention is defined by the appended claims.

With regard to the choice of material for the components included in the arrangement according to the invention, one can imagine both different metal alloys and polyrner materials. When choosing materials, a number of different factors should be taken into account, such as price, weight, strength, appearance and friction. Having considered these factors, and what is stated in the above description and shown in the accompanying ur gures, the person skilled in the art can make a suitable material choice for the application in question.

Embodiments are also conceivable within the scope of the invention where the number of rolling means is greater than three and / or with more than one parking station and locking station.

Furthermore, within the scope of the invention, embodiments are also conceivable where, seen from the viewer's side, the cover units are swung out to the right or to the left, and embodiments where the parking station or stations are to the left and / or to the right.
