Definitions

• the present invention relates to a building front element comprising two opposite and parallelly extending guiding profiles adapted to be placed in a generally vertical position, defining lowermost and uppermost ends, two displaceabie frames being of substantially the same weight and being received in and guided in respective slideways in the guiding profiles and each having opposite and parallel lateral edges, and a wire system connecting one of the edges of the displaceabie frame, being received in and guided in the appertaining slideway in one of the guiding profiles or in the first guiding profile, to the opposite edge of the second dis ⁇ placeabie frame which is received in and is guided in the appertaining slideway of the second guiding profile which wire system in addition connects one of the edges of the above mentioned displaceabie frame which is received in and guided in the appertaining slideway of the second guiding profile, to the opposite edge of the second displaceabie frame which is received in and guided in the appertaining slideway in one of the guiding profiles or in the first guiding profile, and which wire system is guided around the above mentioned uppermost ends of the guiding profiles.
• a building front element of the kind described above is known from Danish utility model registration No. 9300123 and is characterized by differing from the building front elements disclosed in the above mentioned publications by having window frames which are not especially likely to block by wedging and thus to prevent an effortless and reliable mobility and operation.
• This elimination of blocking by wedging or poor or unreliable function which is often present in the above mentioned older building front elements is obtained by means of two wires constituting a cross suspension which serves the purpose of ensuring that the two displaceabie frames of the building front element to the extent possible are always guided in parallel and in balanced state or in an equilibrium.
• An object of the present invention is to provide a building front element of arbitrary size and of the kind described above which compared to the building front element known from the above mentioned Danish utility model registration provides the further advantage that the cross suspension of the building front element may be established in a simple manner without requiring exact adjustment of the two wires of the wire system known from the above mentioned Danish utility model registration in relation to each other and in relation of the two displaceabie frames of the building front element and thus in relation to construction and operation improves the building front element known from the above mentioned Danish utility model registration.
• this object is achieved by means of a building front element of the aforementioned kind, which building front element in accordance with the realization upon which the present invention is based is characterized in that the wire system comprises a single wire which is guided around the lowermost edge of the two dis ⁇ placeabie frames which is arranged lowermost in the building front element constituting a closed loop.
• the building front element known from the above mentioned Danish utility model registration is improved by making the wire system of the building front element so to speak self-adjusting as the closed loop formed by one of the wires of the wire system provides a self-adjusting adaption of the parts of the wire corresponding to the two cros suspension- forming wires of the building front element known from the above- mentioned Danish utility model registration.
• the construction of the cross-suspended wire system as a closed loop facilitates the handling of the building front element.
• any changes in the length of the wires due to use or aging of the two wires of the building front element known from the above mentioned Danish utility model registration is in itself counterbalanced in the building front element according to the present invention, in which the wire system constitutes a closed loop comprising one single wire simultaneously establishing the self-adjusting cross suspension which in accordance with the construction known from the above mentioned Danish utility model registration provides an effortless and friction ⁇ less mobility and at the same time provides the possibility of positioning of the two displaceabie frames in arbitrary positions, e.g. a totally open or a totally closed position and an arbitrary inter ⁇ mediate partly open or partly closed position.
• a primary use of the building front element according to the present in ⁇ vention is for confining e.g. verandas, balconies, pavement restaurants and the like, where these objects should be opened or closed easily, however still maintaining breastwork.
• the building front element accord ⁇ ing to the present invention may, however, alternatively be employed as a window element.
• the displaceabie frames preferably constitute window frames re ⁇ closing glass panes of one or more glass sheets, e.g. hardened single- layer glass panes, two- or three-layered insulating panes.
• the dis ⁇ placeabie frames may, alternatively, constitute covering panels, e.g. in connection with pavement restaurants or shops providing an enclosure and cover for display- or facade areas during the closing hours of the restaurant or shop in question.
• the dis- placeable frames of the building front element according to the present invention may be formed with reinforcements, e.g. a grid or a wire.
• the two displaceabie frames may be received in separate or respective slideways of the guiding profiles.
• each of the guiding profiles is formed with a single slideway for guiding respective lateral edges of the two displaceabie frames, said two displaceabie frames being guided in the same slideway of the two guiding profiles.
• the wire of the wire system of the building front element according to the present invention constitutes the above-mentioned cross suspension and may lead from one edge of the first displaceabie frame to the opposite edge of the second displaceabie frame via bushings, rollers or, in accordance with the presently preferred embodiment of the building front element according to the present invention, around respective reels, arranged at said uppermost ends of the guiding profiles, the two wires further, and preferably, being fixed to the uppermost edges of the two displaceabie frames.
• the building front element according to the present invention may alone be formed by the two opposite and mutually parallel guiding profiles, the two displaceabie frames with their associated wires constituting the cross suspension, characteristic of the present invention.
• the building front element further comprises two fixed frames placed between the guiding profiles at their uppermost and lowermost ends, respectively, defining an uppermost and a lowermost fixed frame, respectively.
• These uppermost and lowermost frames may be of identical dimensions, or different dimensions, and may, additionally, be identical to or different from the displaceabie frames, which may again be of different sizes, as long as the displaceabie frames are of the same weight or, alternatively, are balanced to an essentially identical weight.
• all four frames i.e. the two dis ⁇ placeabie frames and the two fixed frames, are of identical dimensions, thus providing a building front element which, with the displaceabie frames being in their closed position, closes off the building front element completely, and with the displaceabie frames being in their opened position, provides an approximately 50 per cent opening of the area of the building front element.
• the fixed frames may be fixated in the guiding profiles or may be received in respective, separate slide ⁇ ways of the guiding profiles, whereby the fixed frames, e.g. for reasons of cleaning and maintenance, may be released from the normally locked or fixed positions and displaced relative to the normal, fixed positions, guided by the respective slideways of the guiding profiles.
• the slideway receiving the uppermost fixed frame is preferably placed externally relative to the tracks receiving the displaceabie frames and the lowermost fixed frame, relative to the intended position of the building front element, while the track receiving the lowermost fixed frame, correspondingly is placed internally.
• the uppermost fixed frame overlapping the uppermost displaceabie frame which, e.g. via a drip nose, overlaps the lowermost displaceabie frame, which again over ⁇ laps the lowermost fixed frame.
• the easy access to the two displaceabie frames of the building front element through the fixed frames formed as window elements that can be opened may be further improved if the uppermost fixed frame, as seen relative to the intended positioning of the building front element, can be opened outwardly whereas the lowermost fixe frame correspondingly may be opened inwardly.
• the building front element may comprise top and bottom elements joined to the guiding profiles and thus forming an integral frame, of which the guiding profiles constitute frame elements.
• the resulting building front element constitutes an independent unit, of which the bottom element may, preferably, be formed with a drip nose for eliminating possible de- watering problems.
• the building front element according to the present invention preferably constitutes a building front element of a height matching the given and intended use.
• the building front element may advantageously be of a total height which matches the height between two floors.
• the height of the lowermost fixed frame pre ⁇ ferably corresponds to the breastwork of a balcony.
• the building front element according to the present invention may be manufactured from any suitable and, preferably, weatherproof material, such as aluminium, plastic or pressure- or vacuum-impregnated wood.
• the building front element may also be manufactured by combining elements of any of the above-mentioned materials.
• the building front element may ad ⁇ ditionally comprise elements made of e.g. iron profiles formed with a protecting surface coating, e.g. of plastic.
• the wires which according to the present invention constitute the cross suspension, characteristic of the present invention may be produced from any suitable material, such as steel or plastic or any combination thereof, e.g. steel wire covered with plastic of a thickness of e.g. 4 to 8 mm.

• the building front element as a whole, is designated 10 and comprises two opposite and parallelly ex ⁇ tending, lateral elements 12 and 14 which together with opposite top and bottom elements 16 and 18, respectively, form a frame which receives two stationary frames 20 and 26 together with two displaceabie frames 22 and 24 which in the positioning of the building front element according to Fig. 1, wherein the building front element is mounted in a generally vertical position, form vertically displaceabie frames.
• the fixed frame 20 comprises a circumferential outer, marginal frame 21 and forms an up ⁇ permost fixed or stationary frame, while the other fixed frame 26 in the same manner has a circumferential, outer frame 27 and forms a lowermost fixed or stationary frame.
• the displaceabie frames 22 and 24 each com ⁇ prises respective circumferential outer, marginal frames, 23 and 25, re- spectively.
• Reels or tackles for wires 34 and 35 are mounted at the upper ends of the lateral elements 12 and 14, the use of which will be apparent from the following description.
• Fig. 2 shows a vertical section through the building front element of Fig. 1 and showing in detail the fixed frames 20 and 26, the dis ⁇ placeabie frames 22 and 24 together with top and bottom elements 16 and 18.
• Fig. 2 shows that the marginal edges of each of the displaceabie and stationary frames are made up from segments of profiled strips carrying suitable sealing strips and serving to receive and fix respective window panes, formed by hardened single-layer glass windows or multiple-layer insulating windows.
• the top and bottom elements 16 and 18 each carries, as seen in Fig. 2, one slideway; it should be noticed that the lateral elements 12 and 14 shown in Fig. 1, correspondingly comprise one slide ⁇ way.
• the top element 16 accordingly, is provided with two downwardly extending flanges 16a and 16b, therebetween bordering said slideway and constituting an inwardly and an outwardly protruding flange, respective ⁇ ly, as seen relative to the intended positioning of the building front element.
• the uppoermost fixed frame 20 is received, while the slideway serves the purpose of receiving the two vertically displaceabie frames 22 and 24.

• Fig. 2 also shows a wire 36 attached at 40 to the upper edge of the uppermost displaceabie frame 22.
• the wire 36 passes around reels 33 and 35 received in a bracket 30 in a closed loop.
• Fig. 3 illustrates the manner in which the reels 33 and 35 are placed at the uppermost end of the lateral element 12, while reels 32 and 34 are arranged at the corresponding uppermost end of the lateral element 14, and received in a corresponding bracket 30.
• Fig. 3 furthermore illustrates the manner in which the wire 36 passes at the uppermost end of the building front element 10 in a crosslike way. This cross- suspension of the vertically displaceabie frames 22 and 24 also appears from Figs. 4, 5 and 6; Fig.
• This cross suspension in a closed loop of the displaceabie frames 22 and 24 allows for an almost ideal guiding of the vertically displaceabie frames which are, at any time, guided mutually parallel and in equilibrium, any tendency of one of the displaceabie frames to tip over relative to an intended guiding in the lateral elements 12 and 14 automatically being compensated by this cross suspension, and moreover the closed loop pro- vides a self adjustment of the wire 36 in both sides in relation to the displaceabie frames 22 and 24 which accordingly provides a self- realigning effect. Consequently, the cross suspension does not only provide a static balancing of the two displaceabie frames 22 and 24, having the same external dimensions and weight, but also a dynamic balancing providing an easy, frictionless displacement.
• the cross- suspension also allows for a positioning of the displaceabie frames at any position, either fully closed as shown in Fig. 4, partially opened as shown in Fig. 6, or in any intermediate position, fx a semi-open position as shown in Fig. 5.

• Fig. 8 shows a vertical section through the building front element 10 described above with reference to Figs. 1-6, further showing the mounting of the building front element between two adjacent building components 60 and 62.
• Fig. 8 also shows how the upper fixed frame 20 is intended to be placed outermost, while the lower fixed frame 26 is in ⁇ tended to be placed innermost, thus providing a particularly simple de- watering of the building front element.
• the wires 36 may be mounted freely accessible and visible, or as it is the case in the presently preferred embodiment of the building front element according to the present invention and as illustrated with re- ference to Figs. 1-8, it my be fixed concealed in the profiles con ⁇ stituting the side elements 12 and 14 in which the displaceabie frames are guided.
