Definitions
- the present invention relates to a device for foldable covering of an opening comprising: a top railing intended to be mounted to an upper part of the opening, a bottom railing intended to be mounted to a lower part of the opening, a plurality of sheets arranged between the top railing and the bottom railing such that they together form a covering of the opening, wherein at least one of the sheets is arranged displaceable along the railings and turnable in relation to the railings such that the sheet is placeable at an angle to the railings, at least one hinge pin about which said sheet is turnable, the hinge pin comprising a first part fixedly connected to the sheet and a second part arranged in connection to one of said railings, a locking member arranged to lock said hinge pin in its position along the railing when turning the sheet about the hinge pin.
- Such a device is particularly useful for glazing of balconies and areas outdoors, in which one sometimes wishes to clear the opening by bringing the glazing to one side and fold it.
- the invention is also useful in other applications in which foldable covering of an opening is desired.
- Such a device for foldable covering is known from the patent document US 5 272 839.
- the glazing is folded by moving one sheet of glass at a time along the railing to one side of the opening and there turning them outwardly at an angle of about 90 degrees to the railings. While the sheets of glass are turned outwardly from the railing and when the sheets are folded out the locking member locks the hinge pin such that the sheet is held in its position along the railing. Thus it is prevented that the sheets are displaced along the railing after the sheets have been folded.
- the locking member shown in this document comprises a locking pawl arranged in connection to the hinge pin, a toothed rack arranged in connection to the railing and a spring keeping the locking pawl in place in the rack.
- the hinge pin When the sheet is turned outwardly the hinge pin is locked from movement along the railing by the locking pawl interfering with the rack. In the beginning of the turning, before the locking pawl has yet interfered with the rack, there is a risk that the sheet moves in the railing. To prevent this movement the sheet is provided with a wing-shaped supporting member having a surface arranged to, in the beginning of the turning, make contact with a protruding member mounted on the edge of the sheet. The surface of the wing-shaped member is convex in its shape.
- the patent document US5548926 shows a device for foldable covering of an opening comprising a railing, which in its upper end has been provided with a longitudinal groove in the form of an opening arranged along the railing.
- a number of expansions are arranged along the groove.
- the expansions are intended to receive a stopping member, when turning the sheet.
- the expansion has a radius, which is substantially larger than the width of the groove.
- the stopping member has a first and a second extension, wherein the first extension is substantially smaller than the second extension.
- the stopping member runs wit its first extension across the groove, when the sheet is displaced along the groove 1.
- the stopping member rotates in the expansion and in such a way ends up with its second extension across the groove and in such a way becomes locked from motion along the groove.
- the drawback of such a locking member is that the groove must be provided with expansions and that the stopping member must fit exactly into the expansion in order for it to be possible to turn the sheet. This can be experienced as laborious for a user since it may be difficult and time consuming to fit the stopping member exactly into the expansion.
- Another drawback is that the manufacture of the railing becomes more complicated.
- the patent document US5548926 shows a device for locking a window in an open position.
- the locking device comprises a cam provided with a springy finger.
- the cam has a first and a second extension, wherein the first extension is substantially smaller than the second extension.
- the cam is brought along a longitudinal notch in the window frame.
- the window is locked in a certain position by rotating the cam such that its second extension is across the notch and the springy finger is in contact with a wall of the notch.
- the springy finger thus acts with a force against the wall and locks in such a way the cam towards the wall.
- the drawback with such a locking member is that the cam and the springy finger are expensive and difficult to produce.
- the object of the present invention is to indicate a device for foldable covering of an opening having a locking member, which is simple to use, robust, durable, inexpensive and easy to manufacture.
- the locking member according to the invention comprises only one extra part, i.e. the stopping member, apart from the parts that are already present in the device.
- the stopping member has, in a cross section along the railing, a first extension along a first axis and a second extension along a second axis being perpendicular to the first axis, wherein the first extension is smaller than the second extension.
- Such a locking member is robust, durable and simple to produce and to mount.
- the stopping member comprises two opposite, substantially convex portions intended to bear against the railing when turning the sheet about the hinge pin.
- the convex portions have a substantially uniform radius and the distance between them constitute the second extension of the stopping member. Thanks to these convex portions the stopping member and thus the hinge pin may rotate about its own axis when turning the sheet.
- the railing and the stopping member are shaped such that the stopping member influences the shapes of the walls during the turning such that the groove widens and adapts to the shape of the stopping member. Thanks to that the railing adapts to the shape of the stopping member after some or a few turns, the railing does not need to be provided with any expansions. This means that the sheet may be turned outwardly anywhere along the railing, without the need of fitting the stopping member exactly into any expansion.
- the railing is formed in a material, which is softer than the material in which the stopping member is formed.
- the groove has a width, which is larger than the first extension of the stopping member and somewhat smaller than the second extension of the stopping member. It is an advantage to produce the railing in a softer material than the stopping member, such that the material in the railing can be shaped after the shape of the stopping member when the stopping member is turned in the railing. The first times the sheet is turned it is somewhat heavy but after a few turns the part of the railing cooperating with the stopping member has formed after the stopping member and it is easier to turn the sheet.
- said convex portions (29, 30) are provided with elongate, protruding elements arranged to cut into the railing during the turning.
- the convex portions are provided with threads or transverse notches. This in order to make it even easier for the railing to be shaped after the shape of the stopping member.
- the threads or the protruding portions between the notches cuts into the railing and in such a way widens the part of the railing in which the stopping member is rotated.
- the locking member comprises a guiding member protruding from the railing, which is arranged with one face turned towards the sheet, which face comprises at least one section having a concave surface arranged to cooperate with an edge of the sheet or with a part protruding from the edge, in order to prevent that the hinge pin moves along the railing during an initial phase of the turning of the sheet.
- the locking member In the beginning of the turning, i.e. when the angle between the railing and the sheet still is small, the locking member has not yet begun to lock the hinge pin in its position along the railing.
- the railing is provided with a guiding member with a concave surface.
- the concave surface makes that the guiding member and the edge of the sheet, or the part protruding from the edge, are in contact with each other for a longer part of the turning, in comparison with if the surface would be straight of convex. It is desirable that the guiding member and the edge of the sheet, or the part protruding from the edge, are in contact with each other until the locking member has locked the hinge pin in its position along the railing.
- the sheet comprise two hinge pins arranged in line with each other, about which said sheet is turnable, wherein one hinge pin is arranged in connection to the top railing and the second hinge pin is arranged in connection to the bottom railing, wherein both hinge pins comprises said stopping member.
- both ends of the sheet should be provided with hinge pins, each having a stopping member locking the hinge pin in a position along the railing during the turning of the sheet.
- the stopping member constitutes an elongation of the hinge tap.
- Such a device comprises no extra parts apart from those already present in the device, and is thus even more robust and durable.
- Fig. 1 shows a device for removable covering of an opening according to a first embodiment of the invention.
- the opening is for example arranged in a building.
- the device comprises a top railing 1 intended to be mounted to an upper part of the opening and a bottom railing 2 intended to be mounted to a lower part of the opening.
- the top and the bottom railings 1, 2 are elongate and extend substantially horizontally along the opening.
- the railings 1, 2 are formed in some soft material, preferably some soft metal, for example aluminum.
- the sheets 3 are for example made of some transparent material such as glass or plastic, but can also be made by a non-transparent material such as a laminate.
- the sheets are arranged such that they together form a covering of the opening.
- the sheets form a wall together protecting against cold winds, rain and snow.
- the weather is sunny, it is desirable that the sheets of glass can be moved aside to let in sun and warmth.
- the sheet 3 is in its upper end provided with an upper supporting profile 4 carrying the sheet and the sheet is in its lower part provided with a lower supporting profile 5.
- the upper and the lower supporting profiles are fixedly mounted to the sheet and are preferably formed in aluminum.
- the upper supporting profile 4 is provided with a first and a second wheeling arrangement 7, 8 arranged to roll along the top railing 1.
- the lower supporting profile 5 is in the same way provided with two wheeling arrangements 9, 10 arranged to roll along the bottom railing.
- the first wheeling arrangement 7, 9 is arranged in one end of the supporting profile 4, 5.
- the second wheeling arrangement 8, 10 is fixedly mounted in the vicinity of the opposite end of the supporting profile. The distance between the end of the supporting profile and the second wheeling arrangement 8, 10 differ for different sheets 3.
- the sheet 3 is turnable about two hinge pins 12, 14 arranged in line with each other and perpendicular to the extension of the railings. The sheet 3 is thus turnable about an axis perpendicular to the length axis of the railings 1, 2.
- An upper hinge pin 12 extends from the upper supporting profile 4, through the wheeling arrangement 7 and into the top railing 1.
- a lower hinge pin 14 extends from the lower supporting profile 5, through the wheeling arrangement 9, and into the bottom railing 2.

Description
- The present invention relates to a device for foldable covering of an opening comprising: a top railing intended to be mounted to an upper part of the opening, a bottom railing intended to be mounted to a lower part of the opening, a plurality of sheets arranged between the top railing and the bottom railing such that they together form a covering of the opening, wherein at least one of the sheets is arranged displaceable along the railings and turnable in relation to the railings such that the sheet is placeable at an angle to the railings, at least one hinge pin about which said sheet is turnable, the hinge pin comprising a first part fixedly connected to the sheet and a second part arranged in connection to one of said railings, a locking member arranged to lock said hinge pin in its position along the railing when turning the sheet about the hinge pin.
- Such a device is particularly useful for glazing of balconies and areas outdoors, in which one sometimes wishes to clear the opening by bringing the glazing to one side and fold it. The invention is also useful in other applications in which foldable covering of an opening is desired.
- Such a device for foldable covering is known from the
patent document US 5 272 839. The glazing is folded by moving one sheet of glass at a time along the railing to one side of the opening and there turning them outwardly at an angle of about 90 degrees to the railings. While the sheets of glass are turned outwardly from the railing and when the sheets are folded out the locking member locks the hinge pin such that the sheet is held in its position along the railing. Thus it is prevented that the sheets are displaced along the railing after the sheets have been folded. The locking member shown in this document comprises a locking pawl arranged in connection to the hinge pin, a toothed rack arranged in connection to the railing and a spring keeping the locking pawl in place in the rack. When the sheet is turned outwardly the hinge pin is locked from movement along the railing by the locking pawl interfering with the rack. In the beginning of the turning, before the locking pawl has yet interfered with the rack, there is a risk that the sheet moves in the railing. To prevent this movement the sheet is provided with a wing-shaped supporting member having a surface arranged to, in the beginning of the turning, make contact with a protruding member mounted on the edge of the sheet. The surface of the wing-shaped member is convex in its shape. - One drawback with the device shown in said document is that the locking member is complicated, comprises several parts and can therefore easily fail.
- The patent document US5548926 shows a device for foldable covering of an opening comprising a railing, which in its upper end has been provided with a longitudinal groove in the form of an opening arranged along the railing. A number of expansions are arranged along the groove. The expansions are intended to receive a stopping member, when turning the sheet. The expansion has a radius, which is substantially larger than the width of the groove. The stopping member has a first and a second extension, wherein the first extension is substantially smaller than the second extension. The stopping member runs wit its first extension across the groove, when the sheet is displaced along the
groove 1. When the sheet is turn outwardly, the stopping member rotates in the expansion and in such a way ends up with its second extension across the groove and in such a way becomes locked from motion along the groove. The drawback of such a locking member is that the groove must be provided with expansions and that the stopping member must fit exactly into the expansion in order for it to be possible to turn the sheet. This can be experienced as laborious for a user since it may be difficult and time consuming to fit the stopping member exactly into the expansion. Another drawback is that the manufacture of the railing becomes more complicated. - The patent document US5548926 shows a device for locking a window in an open position. The locking device comprises a cam provided with a springy finger. The cam has a first and a second extension, wherein the first extension is substantially smaller than the second extension. The cam is brought along a longitudinal notch in the window frame. The window is locked in a certain position by rotating the cam such that its second extension is across the notch and the springy finger is in contact with a wall of the notch. The springy finger thus acts with a force against the wall and locks in such a way the cam towards the wall. The drawback with such a locking member is that the cam and the springy finger are expensive and difficult to produce.
- The object of the present invention is to indicate a device for foldable covering of an opening having a locking member, which is simple to use, robust, durable, inexpensive and easy to manufacture.
- This object is achieved with the device for foldable covering of an opening such as the one described in
claim 1. - A locking of the movement of the hinge pin along the railing is achieved when the sheet is turned outwardly from the railings and forms an angle to them. The locking member according to the invention comprises only one extra part, i.e. the stopping member, apart from the parts that are already present in the device. The stopping member has, in a cross section along the railing, a first extension along a first axis and a second extension along a second axis being perpendicular to the first axis, wherein the first extension is smaller than the second extension. Such a locking member is robust, durable and simple to produce and to mount. The stopping member comprises two opposite, substantially convex portions intended to bear against the railing when turning the sheet about the hinge pin. The convex portions have a substantially uniform radius and the distance between them constitute the second extension of the stopping member. Thanks to these convex portions the stopping member and thus the hinge pin may rotate about its own axis when turning the sheet.
- According to the invention the railing and the stopping member are shaped such that the stopping member influences the shapes of the walls during the turning such that the groove widens and adapts to the shape of the stopping member. Thanks to that the railing adapts to the shape of the stopping member after some or a few turns, the railing does not need to be provided with any expansions. This means that the sheet may be turned outwardly anywhere along the railing, without the need of fitting the stopping member exactly into any expansion.
- According to an embodiment of the invention the railing is formed in a material, which is softer than the material in which the stopping member is formed. With advantage the groove has a width, which is larger than the first extension of the stopping member and somewhat smaller than the second extension of the stopping member. It is an advantage to produce the railing in a softer material than the stopping member, such that the material in the railing can be shaped after the shape of the stopping member when the stopping member is turned in the railing. The first times the sheet is turned it is somewhat heavy but after a few turns the part of the railing cooperating with the stopping member has formed after the stopping member and it is easier to turn the sheet.
- According to a further embodiment of the invention said convex portions (29, 30) are provided with elongate, protruding elements arranged to cut into the railing during the turning. For example the convex portions are provided with threads or transverse notches. This in order to make it even easier for the railing to be shaped after the shape of the stopping member. The threads or the protruding portions between the notches cuts into the railing and in such a way widens the part of the railing in which the stopping member is rotated.
- According to a further embodiment of the invention the locking member comprises a guiding member protruding from the railing, which is arranged with one face turned towards the sheet, which face comprises at least one section having a concave surface arranged to cooperate with an edge of the sheet or with a part protruding from the edge, in order to prevent that the hinge pin moves along the railing during an initial phase of the turning of the sheet. In the beginning of the turning, i.e. when the angle between the railing and the sheet still is small, the locking member has not yet begun to lock the hinge pin in its position along the railing. In order to prevent that the sheet slides backwards along the railing during this initial phase the railing is provided with a guiding member with a concave surface. The concave surface makes that the guiding member and the edge of the sheet, or the part protruding from the edge, are in contact with each other for a longer part of the turning, in comparison with if the surface would be straight of convex. It is desirable that the guiding member and the edge of the sheet, or the part protruding from the edge, are in contact with each other until the locking member has locked the hinge pin in its position along the railing.

- Fig. 1 shows a device for removable covering of an opening according to a first embodiment of the invention. The opening is for example arranged in a building. The device comprises a
top railing 1 intended to be mounted to an upper part of the opening and abottom railing 2 intended to be mounted to a lower part of the opening. The top and thebottom railings railings - Between the top and the bottom railings a number of
sheets 3 are arranged displaceable along therailings sheets 3 are for example made of some transparent material such as glass or plastic, but can also be made by a non-transparent material such as a laminate. The sheets are arranged such that they together form a covering of the opening. The sheets form a wall together protecting against cold winds, rain and snow. On the other hand, if the weather is sunny, it is desirable that the sheets of glass can be moved aside to let in sun and warmth. By moving thesheets 3 aside and turning them at a 90-degree angle in relation to the railings the entire or part of the opening may be cleared and glass cleaning can be performed from inside the balcony or the outdoor area. - The
sheet 3 is in its upper end provided with an upper supportingprofile 4 carrying the sheet and the sheet is in its lower part provided with a lower supportingprofile 5. The upper and the lower supporting profiles are fixedly mounted to the sheet and are preferably formed in aluminum. The upper supportingprofile 4 is provided with a first and asecond wheeling arrangement top railing 1. The lower supportingprofile 5 is in the same way provided with two wheelingarrangements first wheeling arrangement profile second wheeling arrangement second wheeling arrangement different sheets 3. - The
sheet 3 is turnable about two hinge pins 12, 14 arranged in line with each other and perpendicular to the extension of the railings. Thesheet 3 is thus turnable about an axis perpendicular to the length axis of therailings upper hinge pin 12 extends from the upper supportingprofile 4, through the wheelingarrangement 7 and into thetop railing 1. Alower hinge pin 14 extends from the lower supportingprofile 5, through the wheelingarrangement 9, and into thebottom railing 2. Thetop railing 1 is provided with anopening 15, through which thewheeling arrangement 8 can pass when turning thesheet 3. An analogous opening is arranged in thebottom railing 2. When the device is to be folded thesheets 3 are moved one at a time to one end of the opening and the sheets are turned such that they stand in a 90-degree angle to the opening. - Fig. 2 shows in closer detail the appearance of the
wheeling arrangement 7 and thehinge pin 12. The wheelingarrangement 7 comprises two parallel wheels wherein onewheel 17 is visible in the figure. Further, the wheelingarrangement 7 comprises abody 19 upon which the wheels are suspended. The wheels run along aflange 18 extending along thetop railing 1. In the upper end of the top railing 1 alongitudinal groove 20 or a notch is arranged, extending along the entire length axis of the railing. Thehinge pin 12 is pole shaped and is in its lower end fixed to the upper supportingprofile 4 of thesheet 3 and comprises in its upper end a stoppingmember 22. The stoppingmember 22 extends into thegroove 20 and is arranged to run along the groove when thesheet 3 is parallel to therailing 1. Thebody 19 is provided with a through-hole, intended to receive thehinge pin 12. Thehinge pin 12 is arranged turnable in a relation to thebody 19. The stoppingmember 22 constitutes the upper part of thehinge pin 12. The stopping member has a length axis coinciding with the length axis of the hinge pin. The stopping member is fixedly connected to or is a part of the hinge pin. Thus a turning of the hinge pin also causes a turning of the stopping member. The stopping member is made of a material, which is harder than the material of which theprofile 1 is made, for example of steel. - Fig. 3 shows a cross section through the
profile 1 along a section A-A in fig. 2. Therailing 1 comprises a protrudingpart 24, which extends along the entire length of the railing and has a substantially U-shaped cross section. The protrudingpart 24 comprises twoparallel walls member 22. Thewalls groove 20. When thesheet 3 is in parallel with the top and the bottom railings thestop member 22 can run freely in thegroove 20 and the sheet is displaceable along the railings. - Fig. 4 shows how the stopping
member 22 cooperates with thegroove 20, when thesheet 3 stands at a 90 degrees angle in a relation to the top and bottom railings. Since the stoppingmember 22 is arranged fixedly in relation to thesheet 3, the stopping member is turned when thesheet 3 is turned. - Figs. 5a-5c show how the stopping
member 22 is turned in relation to thegroove 20 when the sheet is turned. Fig. 5a shows a section B-B through the protrudingpart 24 and the stoppingmember 22 in fig. 3. Fig. 5c shows a cross section C-C through the protrudingpart 24 and the stoppingmember 22 in fig. 4. The stoppingmember 22 has a first extension a along afirst axis 32 through the stopping member and a second extension b along a second axis 34, which is perpendicular towards thefirst axis 32. The extension a is substantially smaller than the extension b. For example the extension a is about 4 mm and the extension b is about 6 mm. Thegroove 20 has a width c, which is larger than the first extension a of the stopping member and smaller than or equal to the second extension b of the stopping member. For example c is about 5,5 mm. - The stopping
member 22 is substantially cylinder shaped having two opposite, substantially planer faces and two opposite substantially convex faces. Preferably thehinge pin 12 and the stopping member is made from a screw, on which two opposite sides in the threaded end of the screw has been bevelled. The stoppingmember 22 comprises two opposite, substantiallyconvex portions walls groove 20 when turning the sheet about thehinge pin 12. Theconvex portions member 22 is arranged such that it runs along thegroove 20, with itsfirst axis 22 substantially across thegroove 20 when the sheet is substantially parallel with the railings. Thanks to the first extension a being smaller than the width c of thegroove 20 the stoppingmember 22 and thus thesheet 3 runs easily along therailing 1, as long as the sheet is in parallel with the railings. When the sheet begins to be turned outwardly from the railings, as is shown in fig. 5b, theconvex portions walls - Thanks to the stopping
member 22 having a second extension b, which is equal to or somewhat larger than the width c of thegroove 20 the stoppingmember 22 becomes locked from motion along therailing 20 when the sheet is turned in a relation to the railing. Thanks to theconvex portions convex portions - The stopping
member 22 begins to lock when theconvex portions walls railing 1. This means that thesheet 3 must be turned outwardly to a certain angle before the stopping member begins to lock from motion along the railing. The stoppingmember 22 will always be turned in relation to the railing in approximately the same position along the railing. This means that the walls in the groove at this position will at least partly be hollowed out and shaped by the turning motion of the stopping member. This means that it will be heavy the first times the sheet is turned but the more times the sheet has been turned the turning will be easier. - The figures 6 and 7 show a device according to the invention seen from above. In order to prevent the
hinge pin 12 from moving along therailing 1 during an initial phase of the turning of thesheet 3, i.e. before theconvex portions walls railing 1 is provided with a guidingmember 40 arranged with one face turned towards thesheet 3 during the beginning of the turning. The face comprises at least onesection 42 having a concave surface, which is arranged to cooperate with some protruding part arranged on the upper part of the sheet. In this embodiment example theface 42 cooperates with the wheelingarrangement 8. The guidingmember 40 and thewheeling arrangement 8 are arranged in such a way that they are in contact with each other during the initial phase of the turning of the sheet and in such a way are prevented the sheet and the hinge pin from moving along therailing 1. Thanks to theconcave surface 42 the guidingmember 40 holds thesheet 3 in place during the entire initial phase of the turning. - The present invention is not limited to the embodiments shown but can be varied and modified within the framework of the following claims.
