Description

MEDIA SUPPORT FOR AN EXAMINATION DEVICE DESCRIPTION OF THE INVENTION The present invention relates to a means for holding a concealing device in a frame structure with frame members comprising upper and lower members as well as side members and covering an opening in a particular building a door or a window, the means comprises a first pair of bracket members for mounting to each on a pair of opposed parallel frame surfaces of the frame structure, and a second pair of tie members each provided with a means which can be engaged by a means of engagement in the examination device, each of the bracket members and each of the joining members further comprises a meshing means for seating a connecting member with a bracket member. Concealing devices for windows and doors such as roller blinds, venetian blinds, folding blinds and internal and external locks are conventionally provided together with support brackets which are specifically adapted to the particular shape of the concealment device and can be coupled by a means of engagement that is provided in the concealing device, typically at either end thereof. During the installation of the concealment device the support brackets can be assembled by the user himself which often results in errors in particular in different left and right brackets which are scrambled. Although it is also known to incorporate support brackets for a specific type of concealment devices in the frame structures of doors and windows during the production thereof in such a way that the frame structure of the door or window is supplied with previously mounted support brackets. , such brackets are normally designed for use with a specific class of concealment devices such as roller shutters. If another kind of concealment devices such as a Venetian blind is installed, it may be necessary in such a case to replace the previously mounted support brackets by brackets designed specifically for the desired concealment device. In addition, the inevitable production of tolerances for the door or window frame structure can result in difficulties with regard to a correct mounting of a concealment device, whereby the secure mounting of a concealment device to the frame structure occasionally occurs. It can only be obtained by using additional fastening screws. DE 30 48 333 discloses a support means for a rolled shutter comprising two support plates, one of which is provided with a slot for receiving a square pin at one end of the spring roller tube of the shutter rolled in a rotationally immobilized manner and the other is provided with a circular hole. For an alternative mounting of a Venetian blind, each support plate is provided with projections for engaging grooves in connecting members connected to the upper cover of the Venetian blind, the members are pushed onto the support plates. Subsequently, the lateral guide of the shutter slats are assembled, the slats serve simultaneously as a support for the umion members and the upper cover of the shutter, that is, as a security against the disconnection of the connecting member from the plate of support. Although this support distribution allows the use of the same support brackets for different concealment devices, a disadvantage of this design is that they are for use with differently designed roller shutter support brackets to receive the spring roller tube from the rolled shutter, that is to say, the slot and the circular hole, respectively, they are what is required. In US-A-3, 614, 045 there is described a support distribution comprising elongated slotted rails secured to the side members of the frame structure and extending through the height thereof and engaging members that are provided with a hook-shaped joint member for engaging in the grooves of the rails and projecting at right angles to the front of the frame structure. The less attractive appearance of this distribution limits its application to draperies, which will conceal the distribution of support and is not adequate to meet the current demands regarding aesthetic and functional designs of windows and accessories as concealment devices. EP-A1-0, 465, 433 discloses a distribution comprising a pair of identical tube-shaped support brackets fixed to opposite surfaces of frame side members in each of which a transverse recess is formed to receive a resilient holding member in a way that restores the outer cylindrical shape of the support brackets. This design is only considered for roller shutters that have a coupling means in the form of cylindrical bolts that project at both ends. WO 96/07007 discloses a roll-up awning mounted between a pair of support brackets projecting at right angles from the front side of the frame structure and which are formed with a cut-out slot for receiving a joint member in the form of a slide coupled by the roller blind. In SE-B-415, 904, there is described a roller shutter support comprising a pair of L-shaped bracket members in which the edge flange portions on both sides of a rectangular slider are coupled by legs resilient of an insertion slide which can be pushed into the recess and is engageable by a means of engagement in the roller shutter. With this background, the object of the present invention is to provide a support means for mounting a concealing device in a rectangular frame structure covering an opening in a building, preferably in the window frame, which has an attractive design that satisfies the demands of the current user regarding the quality of design and the ease and low cost of manufacture and installation of which is simplified by a design that is self-aligned and that can largely compensate for production tolerances . A further objective is to provide a standard design of a first pair of support brackets which can be preassembled in the frame structure at the production site whereby a simple installation of various concealment devices using various forms of union members. According to the invention, these objects are met by the support means identified above, characterized in that the bracket members of the first pair are identical standard members for mounting on opposite frame surfaces, each comprising a relatively flat front part which protrudes from the frame surface in the assembled position of the bracket member and which have a substantially uniform external surface and wherein the engagement means is provided by each joint member and comprises a first gear means in the form of at least one surface of. contact in the joint member contacting the circumferential surface portion of a bracket member to provide temporary seating therewith and a second non-resilient engagement means which provides a stable seating of the joint member with respect to the structure of frame. By making the members of corbel as identical standard members the production of them becomes simple and cheap. The bracket members typically can be mounted on opposite surfaces of the window frame or side frame members facing the illumination area of a window and immediately below the upper member of the window frame or frame. Alternatively, the bracket members can also be mounted, however, on opposite surfaces of the window frame or the upper and lower frame members to accommodate a concealing device which can be moved in the horizontal direction. In addition, the bracket members can be assembled with the circumferential surface portion provided for temporary seating with the joint member contact surface extending on both sides in the longitudinal direction of the frame or the window frame members. in which they are mounted or, transversally to it. By this latter orientation, the subsequent assembly of the joining members in the bracket members becomes particularly simple, since the joining members can be pushed over the bracket members from the inner side of the window in a right angle direction with respect to the plane of the window glass. In addition, the provision of the settlement means in the form of a first and second seating means for the temporary and stable seating of the connecting member with respect to the bracket member and the frame or window frame structure, respectively, facilitates installation of a concealment device. As will be further apparent from the description that follows, the first engagement means may be designed for a very simple temporary distribution of the concealment device with coupling members followed by provision or a stable and reliable attachment of the attachment members with respect to to the frame or the structure of the window frame, while the joining members are kept in temporary settlement with respect to the bracket members. In general, the cantilever members serve a dual purpose, specifically on the one hand they provide an accurate placement of the joint members and therefore the concealment distribution with respect to the frame structure and, on the other hand, to adapt the load of the concealment distribution after the establishment of the stable settlement of the union member with respect to the framework structure and the transfer of this burden to the structure of; frame. Preferred but not limiting embodiments of the support means according to the invention are set forth in the dependent claims. The invention will be described in the following with reference to the schematic drawings, in which: Figure 1 shows an embodiment of the support means distributed in a side frame member or the window frame structure of a window in the roof, the Figure 2 is a sectional view of the distribution of the support means illustrated in Figure 1, Figures 3 and 4 show two alternative designs of a support member joining member, Figures 5 to 7 show additional alternative embodiments. of the support means, Figure 8 shows a perspective view of an alternative embodiment of the support means distributed in the upper left corner of a roof window, Figure 9 shows a perspective view of a concealment device, and the Figure 10 is a view corresponding to that of Figure 8 but in the upper right corner of the window. Figure 1 shows the upper right corner of a roof window with a frame structure including a horizontal top member 1 and a side member 2 extending in a vertical plane. Conventionally, the frame structure, which can be either the main frame of a stationary window or the window frame of an openable window, will comprise a lower member opposite and parallel to the upper member 1 and a side member left opposite to the right lateral member 2 that is illustrated, so that the upper, lower and lateral members together form a rectangular structure that frames the window glass 3. For installation of a concealment distribution such as a roller shutter, a folded shutter, a Venetian blind or the like on the inner side of the window pane 3, a bracket member 4 is fixed on the side member 2 of the frame structure nearby to the horizontal upper member 1 as well as to the opposite left lateral member, which is not illustrated in Figure 1. The bracket member 4 is formed as a pair of identical standard members which may be used for installation of various types of concealment distributions . As shown in the sectional view in Figure 2, each bracket member 4 comprises a relatively flat front portion 5 having a substantially uniform external surface and protruding from the surface of the frame side member 2 and a base section 6 secured to a hole or recess 7 in the frame side member 2 by means of bolts 8 which are provided with external threading 9 or other suitable profiling to ensure firm retention of the bolts in the corresponding perforations 10 pre-drilled in the side member 2 of frame, once the bracket member 4 has been pushed or pushed into the side member 2. Typically, the front part 5, the base section 6 and the profiled bolts 8 projecting from the bracket member 4 are formed in a single integrated piece, for example as a molten or molded member of a suitable metal or plastic or of a composite material. In the embodiment of Figures 1 and 2, the front portion 5 of the bracket member is formed as a generally rectangular planar plate member with two pairs of mutually parallel sides 11 and 12, respectively, but as will be seen from the following In the description, several alternative forms of the front part of the bracket member are also possible.

The projecting front part 5 of each bracket member 4 will typically be pre-assembled in the window frame in connection with the production of windows, and serves to receive and support a supported joint member 13 as a pair of joint members together with the concealment distribution. As shown in Figures 3 to 10, the joining member is provided with a means that can be engaged by engaging means in the concealing device that is typically provided at either end of the concealing device. For a concealing device in the form of a roller shutter, the connecting member can be provided, for example, with a square hole 14, as shown in Figure 3 to receive an end arrow of a rod or tube from the blind in a rotationally immobilized manner. According to the present invention, the bracket and the joining members are provided with a meshing means which comprises a first engagement means in the form of at least one contact surface in the joining member that makes contact with the part of circumferential surface of the bracket member to provide temporary engagement therewith, and a second non-resilient engagement means providing stable seating of the attachment member with respect to the window frame structure. In the embodiment shown in Figures 1 to 3, the square hole 14 constitutes the means that can be engaged by the concealment arrangement that is provided in a rigid plate section 15 of the joint member 13 which is connected to a L-shaped arrangement of the two legs 16 and 17, which, as shown by the arrow A in Figure 1, can be pushed onto the bracket member 4 from an internal side of the frame structure in an angled direction straight with respect to the side member 2 with the legs 16 and 17 engaging adjacent lateral edges 11 and 12 of the front portion 5 in projection of the bracket member 4. Therefore, the surfaces of the legs 16 and 17 facing the open recesses 18 defined by the legs 16 and 17 and the plate section 15 form contact surfaces of the joint member 13 which engages the circumferential surface portions of the body. member 4 of bracket that is formed by the lateral edges 11 and 12 to provide temporary seating of the joint member 13 with the bracket member 4. Subsequently, the stable seating of the connecting member 13 with respect to the frame structure is established by a second engaging means which as shown may comprise a nail or screw 19 inserted through a hole 20 in one of the legs 16. and 17 within the underlying lateral member 2. As shown in Figures 1 and 3, the temporary placement of the joining member 13 can be further facilitated by forming the free end of one of the legs such as the leg 16 with a pressure setting means such as a short hook 21 which meshes with the other of the short sides 12 of the bracket member 4. In the embodiment shown in Figure 4, the L-shaped array of the legs 16 and 17 connected to the plate section 15 in Figure 3 has been replaced by a U-shaped configuration of the legs 22 which is project from a lower part 23 of the joining member 24. As in the embodiment in Figure 3, the free end of each of the projection legs 22 is formed with a pressure setting means 25 which has been pressurized with a hook. The joining member 24 in Figure 4 can be easily placed in temporary seating with the rectangular front portion 5 of the bracket member 4 in Figure 1 by sliding the U-shaped configuration of the legs 22 upwards in the longitudinal direction of the body. member 2 on the frame side, as illustrated by the arrow B. Therefore, the projecting legs 22 will provide sufficient elastic deformation capacity to allow the pressure setting means 25 at the free end of each of the legs 22 is in settling by pressure with the upper long side 11 of the front part 5 of the bracket member, when the joining member 24 is pushed upwards to place the lower part 23 in contact with the lower long side 11. Subsequently, the stable settlement of the joining member with respect to the frame structure can be established in the same manner as described above by means of a nail or screw which is inserted into the frame side member 2 through a hole 27. in the lower part 23. As shown in Figures 5 to 10, other different designs of the bracket and joint members are possible. In Figure 5, the front portion 28 of the bracket member is generally formed as a trapezium with upper and lower sides 29 and 30 converging towards each other in the direction of the window pane 31 towards the inner side of the frame structure with the upper horizontal member 32 and the lateral member 33. As in the embodiment in Figure 3, the joint member comprises an L-shaped configuration of the legs 34 and 35, of which the leg 34 is formed, however, with a wedge-like shape, so that temporary seating of the connecting member with the bracket member can be provided by sliding the connecting member within the bracket member from the inner side of the window frame in the direction of arrow C, until the wedge-like leg 34 is compressed between the inclined upper side 29 of the front part 28 and the lower side of the horizontal frame upper member 32. The stable seating of the joining member with respect to the frame structure can then be provided in the same manner as described above by inserting a nail or screw into the frame side member 33 through a hole 36 that is formed , for example, in leg 35 of joining member. A temporary seating of the connecting member with the bracket member by compression of a leg of the connecting member can also be obtained, for example, with a bracket and a joining member that is formed as shown in Figures 1 and 3 by mounting of the bracket member 4 on the frame side member 2 with a deflection spring in the direction towards the horizontal frame upper member 1 corresponding to the direction of the arrow B, whereby the pressure setting means 25 in Hook shape in Figure 3 can be supplied concurrently. The deflection spring of the cantilever member can be obtained as shown with the dashed lines in Figure 2 by means of a spring such as a leaf spring 37 interposed between the lower side 38 of the base section 6 of the member 4 of bracket and part 39 of opposite edge of the hole or recess 7 in the frame side member 2. Alternatively, the deflection spring may be provided by means of a spring acting between the upper side of the bracket member and the contact surface of the joint member in seating therewith, for example by means of a leaf spring that is mounts on the underside of the corresponding leg 34 of the joint member, or as described in further detail in the following, in relation to the embodiment of Figures 8 to 10. Figure 6 shows a modality, in which the front portion 40 of the bracket member is generally circular and the joining member 41 comprises a generally L-shaped configuration of the legs 42 and 43, in which the lower side of the leg 42 forms a contact surface for seating with the upper circumferential edge portion 44 of the bracket member that is formed with a curvature that coincides with the circular curvature of the front portion. In the same way, to that described above, the temporary seating between the connecting and bracket members can be improved by mounting the bracket member on the side frame member 45 with a biasing spring in the direction of the arrow D. As shown in Figure 7, the temporary seating of the connecting member with respect to the bracket member may alternatively be obtained by forming the contact surface 46 which is provided by a leg 47 of an L-shaped configuration and the circumferential surface portion 48 of the part 49 front of the bracket member with interposed profiling shapes such as a projection groove 50 from the contact surface 46 and a recess 51 for receiving the groove in the surface portion 48.

Although only the portion of connecting members serving to provide a temporary and stable seating with respect to the bracket members and the frame structure, respectively, is understood in Figures 4 to 7, respectively, it is understood that in each embodiment the connecting member it will also comprise a means, such as a square hole 14 in the plate section 15 shown in Figure 3, which can be engaged by a matching means of the concealing device. In Figures 8 to 10 an alternative embodiment is shown in which the joining members 73, 83 to be placed on the bracket members 64 each comprise primarily a disc-shaped configuration. The bracket members 64 may be substantially of the same design as described in connection with the above embodiments, for example as one of Figures 1 to 3, and is mounted on the side members 62a, 62b and on the frame structure near the member. 61 of adjacent horizontal frame. Each connecting member 73, 83 has on its back side, not shown, contact surfaces for contacting at least the upper side of the long sides 71 of the front portion 65 of the bracket member 64 to provide temporary seating with the same. In order to increase the effect of the temporary settlement, each connecting member 73, 83 has on its upper side a means for compressing the connecting member 73, 83 between the long upper side 71 and the front part 65 of the bracket member 64 and the adjacent horizontal frame member 61. In the embodiment shown, this means comprises a flap 75, 85 projecting at an angle from the upper side of the joining members 73 and 83, respectively, and providing a deflection spring between the upper frame member 61 and the member 64 of corbel. Of course, two or more fins can be provided, either side by side, successively or in other geometric distributions. Alternatively, the compression means may comprise a wedge-like projection on the upper side of each joint member. As in the embodiments described above, the stable seating of the connecting member 73, 83 with respect to the frame structure is subsequently established by a second engaging means which may comprise a nail or screw inserted through the hole. 80, 90 and within the underlying lateral member 62a, 62b. In order to further facilitate the distribution of the concealment device in the support means, each of the holes 80, 90 is provided with a circumferential flange 81, 91, for temporary retention of the fastening member. In Figure 9 there is shown a concealment device in the form of a roll-up shutter 100 having at one end a square or rectangular pin 101. The means in the connecting member 73 which can be engaged by the pin 101 comprises an adapter piece 76 having a cross section which is asymmetric with respect to at least one axis and which is placed inside a receptacle 74 in the connecting member 73, as indicated, the adapter piece 76 may be provided together with the concealing device and may comprise an arcuate groove 78.
