Abstract
Description
- The present invention relates to a screen device, comprising:
- a screen roller which is rotatable about an axle;
- a screen which can be rolled up onto and unrolled from this screen roller;
- an interior space in which the screen roller is fittable in order to accommodate the latter in an installed position of the screen device;
- a support element on an end side of the screen roller for fastening the screen roller in the interior space;
- a fastening body which partly delimits the interior space, to which the support element is attachable via a fitting movement virtually perpendicular to the axle of the screen roller;
- a first guide element and a second guide element on the fastening body, which are arranged substantially parallel to each other, between which the support element is retractable and extendable in order to guide the support element during the fitting movement;
- at least one securing element for securing the support element during the fitting movement, wherein this securing element is provided on the support element so as to be movable between a first position and a second position;
- one or more spring-mounted elements which force the securing element to its first position;
- Such screen devices are usually placed near door or window openings, wherein these are placed in such a manner with respect to this door or window opening that the screen can at least partly screen this door or window opening against, for example, sunlight and/or insects and/or cold or heat. Such a screen device may also be used as an unrollable wall or roof element which usually serves as a screen against, for example, sunlight and/or insects and/or cold or heat.
- Screen rollers are typically fitted in an interior space via a movement which is virtually perpendicular to the axle of the screen roller, in which interior space they are to be fastened in a secure manner between fastening bodies, with access to this interior space being provided on one side. Typically, only limited space is available for fitting the screen roller in this interior space in a secure manner. At least this interior space will be screened off by said fastening body and a fastening body on the other side of the screen roller. Typically, only said side via which the screen roller can be fitted in the interior space will be left clear, with the interior space being screened off on all other sides. Access to the interior space is typically determined by environmental factors, such as the presence of a roof or a wall, etc.
- Such screen devices comprising said securing element are described, for example, in
EP 2 813 662EP 2 813 662 - It is an object of the present invention to provide such a screen device in which the securing action can be ensured in a relatively compact way, even with relatively heavy screen rollers.
- This object of the invention is achieved by providing a screen device, comprising:
- a screen roller which is rotatable about an axle;
- a screen which can be rolled up onto and unrolled from this screen roller;
- an interior space in which the screen roller is fittable in order to accommodate the latter in an installed position of the screen device;
- a support element on an end side of the screen roller for fastening the screen roller in the interior space;
- a fastening body which partly delimits the interior space, to which the support element is attachable via a fitting movement virtually perpendicular to the axle of the screen roller;
- a first guide element and a second guide element on the fastening body, which are arranged substantially parallel to each other, between which the support element is retractable and extendable in order to guide the support element during the fitting movement;
- at least one securing element for securing the support element during the fitting movement, wherein this securing element is provided on the support element so as to be movable between a first position and a second position;
- one or more spring-mounted elements which force the securing element to its first position;
- Such rigid projecting fitting elements are able to deal with larger weights than elastic parts. By making a base body of the securing element rigid and uncoupling the spring-mounted elements from the location of the securing arrangement itself and now forming this securing arrangement by means of such a rigid projecting fitting element which engages in a corresponding fitting space, it is ensured that a more secure securing arrangement is produced. Even when the spring force of the spring-mounted elements decreases or the spring-mounted elements fail, such a projecting rigid fitting element will continue to engage in the corresponding fitting space in the installed position and continue to ensure the securing action, unless it is actively removed from this fitting space.
- The support element is in this case preferably provided with said securing element. In this case, the securing element may then form part of the support element or may be fastened to the support element as a separate part in order to fit this securing element on the support element.
- In addition, the first guide element or the fastening body preferably comprises at least one second fitting space which is configured to correspond with the projecting rigid fitting element of the securing element and/or comprises at least one second projecting rigid fitting element which is configured to correspond with the fitting space of the securing element.
- In this way, the support element can be fastened to the fastening body in several steps. This is particularly advantageous in cases where, in addition to the mechanical coupling, an electrical coupling is also produced while the support element is being fastened to the base body. Such an electrical coupling is typically provided where a tube motor is fitted in the screen roller for driving the rotating movement of this screen roller in order to roll up and unroll the screen. Such a tube motor will typically already rotate initially when this electrical coupling is being brought about. When installing a screen roller, it is difficult to hold a screen roller up when such a sudden movement of the screen roller occurs. Due to such a second fitting space and/or a second projecting rigid fitting element, it can be ensured that the screen roller will not fall down completely but remain secured if grip is lost when such a sudden movement of the screen roller occurs. In a first step, a degree of securement is achieved by means of the second fitting space and/or the second projecting rigid fitting element. Subsequently, in a second step, installation of the support element on the fastening body may be continued, in which case an optional electrical coupling may also be produced in addition to the mechanical coupling.
- With such an embodiment, the second fitting space preferably comprises an engaging incline and/or the second projecting rigid fitting element preferably comprises an engaging incline, in which case the projecting rigid fitting element of the securing element then comprises a corresponding engaging incline and/or in which case the fitting space of the securing element then comprises a corresponding engaging incline, so that, when fastening the support element during the fitting movement, the projecting rigid fitting element of the securing element first engages in the second fitting space and/or the second projecting rigid fitting element engages in the fitting space of the securing element, after which the corresponding engaging inclines engage with each other to return the securing element to its second position, counter to the spring force, and finally, on account of the spring force, to allow the projecting rigid fitting element of the securing element to engage in the former fitting space of the first guide element or the fastening body and/or to allow the first projecting rigid fitting element to engage in the fitting space of the securing element.
- Instead of providing the first guide element or the fastening body with a second fitting space and/or a second projecting rigid fitting element, it is possible, as an alternative or in addition, to provide the securing element with at least one second projecting rigid fitting element which is configured to correspond with the former fitting space of the first guide element or the fastening body and/or to provide at least one second fitting space which is configured to correspond with the former projecting rigid fitting element of the first guide element or the fastening body. Mutatis mutandis, it is then also possible to provide analogous engaging inclines as described above in connection with second fitting spaces and/or second projecting rigid fitting elements in the first guide element.
- The first guide element of a screen device according to the present invention furthermore preferably delimits a guide slot and the support element preferably comprises a corresponding guide rib which engages in this guide slot during the fitting movement, in which case each said fitting space of the first guide element or the fastening body ends in this guide slot and/or each said projecting rigid fitting element of the first guide element or the fastening body extends in this guide slot.
- As an alternative or in addition, the first guide element may also be provided with a guide rib, in which case the support element is provided with a corresponding guide slot, so that this guide rib engages in this guide slot during the fitting movement. A said fitting space of the first guide element may then be provided in this guide rib and/or a said projecting rigid fitting element of the first guide element may then project with respect to this guide rib.
- The securing element is preferably movable between its first position and its second position, substantially in a direction along the axle of the screen roller.
- The securing element is furthermore preferably pivotably fastened to the support element. To this end, the securing element is preferably arranged so as to be pivotable about a pivot axis which extends at right angles to the axle of the screen roller and at right angles to the fitting movement. When the securing element is arranged so as to be pivotable in this way, the pivot movement may be limited in such a manner that a displacement of the securing element in accordance with this pivot movement substantially takes place in a direction along the axle of the screen roller.
- Every dimension of the securing element, preferably in a direction along the axle of the screen roller, is smaller than or equal to the largest corresponding dimension of each of the guide elements. In this way, the securing arrangement can be brought about in a very compact manner, with very little space being required for this purpose between the screen roller and the fastening body, next to the screen roller.
- The securing element is preferably provided with said one or more spring-mounted elements.
These one or more spring-mounted elements are then preferably arranged on the side of the base body opposite the side on which each said projecting rigid fitting element of the base body and/or each said fitting space of the base body is provided. - In a preferred embodiment, not only the first guide element comprises a fitting space and/or a projecting rigid fitting element, but also the second guide element, and the rigid base body of the securing element comprises a projecting rigid fitting element which is configured to correspond with this fitting space of the second guide element and/or a fitting space which is configured to correspond with this projecting rigid fitting element of the second guide element, so that, in the installed position, with the securing element in its first position, each projecting rigid fitting element engages in the corresponding fitting space in order to secure the support element.
In such an embodiment, the spring-mounted elements are preferably arranged between the guide elements, in the installed position of the screen device. - Above, reference was repeatedly made to the securing arrangement of the securing element with respect to the first guide element or the fastening body. It goes without saying that, analogously, it is in each case also possible to adopt improved embodiments of this securing arrangement for securing the securing element with respect to the second guide element. Preferably, with regard to transmission of forces, the securing element is constructed symmetrically here, with this securing element being secured in the same way on both sides with respect to each of the guide elements and/or the fastening body.
Up to now, reference was only made to one securing element. Alternatively, it is for example also possible to provide a separate securing element for each guide element. Preferably, however, only one securing element is provided for both guide elements and/or the fastening body. - A screen device according to the present invention furthermore comprises preferably a blocking element for fixing the securing element in the installed position of the screen device.
It is possible to provide, for example, one or more additional fastening elements as blocking element. Thus, it is for example possible to provide a screw to screw the securing element down in the installed position of the screen device. - The securing element of a screen device according to the present invention furthermore preferably comprises an engaging element for manually moving the securing element from its first position to its second position.
- The present invention will now be explained in more detail by means of the following detailed description of some preferred screen devices according to the present invention. The sole aim of this description is to give illustrative examples and to indicate further advantages and features of these screen devices, and can therefore by no means be interpreted as a limitation of the area of application of the invention or of the patent rights defined in the claims.

This is also referred to as vertical installation. Of course, the present invention is not limited to this vertical installation.
- A screen device according to the invention comprises a screen roller (not shown) which is rotatable about an axle. A screen (not shown) which can be rolled up and unrolled is arranged on this screen roller. The screen roller has to be installed in an interior space which may be situated, for example, above a window or door opening. Often, this interior space is only accessible from the bottom side, as a result of which vertical installation in an upward direction is desirable.
- In order to be able to install the screen roller in the interior space in a simple manner, the screen device comprises a support element (1). In the illustrated embodiments, this support element (1) comprises an axle opening (18) in which the axle can be mounted in order to fit the screen roller so as to be rotatable about this axle. In this way, this support element (1) is provided on the end side of this screen roller.
- The screen device furthermore comprises a fastening body (2) which partly delimits the interior space and to which the support element (1) is attachable. The support element (1) is attachable to the fastening body (2), virtually perpendicularly to the axle of the screen roller, via a fitting movement.
Of both illustrated embodiments, in each case one support element (1) and one fastening body (2) are illustrated. Preferably, such a screen device comprises such a support element (1) and such a fastening body (2) at each end of the screen roller, with the screen roller being rotatably mounted in both support elements (1).
The interior space in which the screen roller is accommodated may be delimited, for example, by a screen casing of which the fastening bodies (2) form part. - The illustrated fastening bodies (2) in each case comprise two guide elements (3, 4) which are arranged substantially parallel to each other and between which the corresponding support element (1) is retractable and extendable for guiding the support element (1) during the fitting movement for installing the support element (1) on the corresponding fastening body (2).
In this case, the guide elements (3, 4) are arranged separate from each other. They could equally from part of, for example, the same U-shaped bracket. These guide elements (3, 4) may form an integral part of the fastening body (2) or may be installed on this fastening body (2).
Each guide element (3, 4) is provided with a guide slot (11) in which in each case a corresponding guide rib (12) of the support element (1) is guided during the fitting movement for fitting the support element (1) to the fastening body (2). - In addition to said support element (1) and said fastening body (2), a screen device according to the present invention also comprises a securing element (5) in order to secure the support element (1) during the fitting movement. In the illustrated embodiments, this securing element (5) is fastened at the bottom of the support element (1).
This securing element (5) is in each case arranged on the support element (1) so as to be movable between a first position and a second position and comprises a rigid base body (6) on which rigid fitting elements (7) are provided which project on the sides of the guide slots (11). In the guide slots (11) themselves, corresponding fitting spaces (9) are provided, in which, in the installed position, the corresponding fitting elements (7) engage in order to secure the support element (1), as can be seen inFigs. 1 and6 .
By engaging at the bottom of the rigid base body (6) of the securing element (5), the securing element (5) can manually be moved from its first position to its second position and vice versa. To this end, the bottom part (16) of the rigid base body (6) always remains accessible in every position of the screen on the screen roller. In this way, a screen roller installed in the interior space can easily be removed again by manually moving the securing element (5) to its second position and sliding the support element (1) out of the guide elements (3, 4). - In the first embodiment, the securing element (5) is pivotably fastened at the bottom of the support element (1). To this end, it is fixed in the support element (1) with pivoting pins (17), so that the securing element (5) is pivotable about a pivot axis which extends at right angles to the axle of the screen roller and at right angles to the fitting movement.
Between the fitting elements (7), the securing element (5) is provided with two spring-mounted legs (8) which drive the securing element (5) to its first position during the fitting movement. These spring-mounted legs (8) may be configured as an integral part of the securing element (5) or may be fitted thereto.
The spring-mounted legs (8) are arranged facing the fastening body (2) and are configured to drive the securing element (5) away from this fastening body (2) to its first position. In the direction towards the fastening body (2), the fitting spaces (9) in the guide elements (3, 4) end in the guide slots (11) in order to allow the fitting elements (7) to engage therein in the first position of the securing element (5). - When fitting the support element (1) with its guide ribs (12) in the guide slots (11), the securing element (5) will first be pushed to its second position by the guide elements (3, 4), counter to the spring force of the spring-mounted legs (8), during the fitting movement. In this embodiment, second fitting spaces (10) are provided in the guide elements (3, 4), under said fitting spaces (9), which second fitting spaces (10) likewise end in the guide slots (11), in the direction facing the fastening body (2). On account of the spring force of the spring-mounted legs (8), the securing element (5) first returns to its first position at the location of these second fitting spaces (10), with the projecting rigid fitting elements (7) engaging in these fitting spaces (10). The fitting elements (7) are provided with an engaging incline (15) and the second fitting spaces (10) are provided with a corresponding engaging incline (14). When the support element (1) is moved further between the guide elements (3, 4), these engaging inclines (14, 15) will engage with one another and the securing element (5) is forced to its second position, again counter to the spring force of the spring-mounted legs (8). Then, the securing element (5) returns to its first position at the location of the former fitting spaces (9) in the guide elements (3, 4), with the projecting rigid fitting elements (7) of the securing element (5) now engaging in these top fitting spaces (9).
As can be seen inFig. 1 , every dimension of the securing element (5) of this embodiment is smaller than or equal to the largest corresponding dimension of each of the guide elements (3, 4) in a direction along the axle of the screen roller. During the fitting movement, the securing element (5) only moves virtually in a direction along the axle of the screen roller, closer to the fastening body (2) to its second position and again further from the fastening body (2) to its first position, in which case it does not project with respect to the guide elements (3, 4). In this way, this securing element (5) is of a very compact design and does not come into contact with the screen roller of the screen, neither in the installed position, nor during the installation operation. - In the second illustrated embodiment, the securing element (5) is coupled to the support element (1) by means of spring-mounted elements (8), wherein this is movable from its first position to its second position, away from the fastening body (2). In this embodiment, the fitting spaces (9) end in the guide elements (3, 4), away from the fastening body (2), to allow the projecting rigid fitting elements (7) to engage in the first position in these fitting spaces (9).
In this embodiment, the screen device also comprises a blocking screw (13) in order to fix the securing element (5) in the installed position of the screen device, as can be seen inFig. 6 .
