Exemplary embodiments of the present invention relate to a frame spar and/or sash spar for a frame and/or a sash of a window, a door or a façade element, and a door, a window, a façade element comprising a frame and a sash made of such frame spars or sash spars, respectively.
Smoke protection doors (RS) according to DIN 18095 are self-closing doors which substantially prevent the passage of smoke in the installed and closed state. A fire protection closure alternatively or additionally has the object of securing openings in walls against the passage of fire. According to DIN 4102-5, there are the following fire protection classes: T30, T60, T90, T120, and T180. The number after the T indicates the duration in minutes, for which duration the fire protection closure prevents the passage of the fire (not of the smoke) and still has to be able to be opened.
The production and manufacturing of known designs meeting these requirements are relatively complex.
Exemplary embodiments of the present invention are directed to a frame spar and/or sash spar for a frame and sash, respectively, of a window, a door, or a façade element, which are each preferably well suitable for a use as a frame spar of a frame and a sash of a smoke protection door or a fire protection door at least according to fire protection class T30 and are to be manufactured easily and precisely to form such a door (or a corresponding window or fagade element, respectively).
A frame spar and/or a sash spar are respectively provided for a frame and/or a sash of a window, a door, or a façade element, which respectively have at least the following features:
The two fastening means on the cover element or elements and/or on the fitting part or parts are each insertable perpendicularly to the transverse leg and parallel to the short leg and the long leg, in order to be fixed in the fastening grooves.
The fastening groove particularly preferably has at least one catch means for locking fixing of at least one corresponding counter catch means of the fitting part and/or the cover element.
According to one particularly preferred embodiment, the at least one cover element is a cover profile which forms a visual rabbet screen. This cover profile is clipped perpendicularly to the transverse leg into the fastening grooves, and therefore it is fixed therein. In this case, the catch connection on the cover profile preferably has enough play according to one variant that a clamping and therefore shear-resistant connection is not formed between the cover profile and the main profile, but rather the cover profile may be manually displaced without tools on the main profile. The cover profile then does not assume a static function—except in case of fire—and does not or does not noticeably stabilize the main profile. It is merely used to cover the gap/free space between the long leg and the short leg on the side thereof facing away from the main leg or transverse leg. The cover profile is preferably longer than 10 cm. It can cover the entire free space/gap between the short leg and the long leg over the complete length and is preferably solely not placed in the region of locks and fitting parts. Of course, a plurality of the cover profiles can also be provided. The sash and the frame are preferably provided with the cover profiles on multiple or even all parts.
Since the cover profile or profiles preferably do not assume a static function, they can simply be clipped onto the main profile perpendicularly to the transverse leg. For this purpose, it is in turn advantageous if the cover profiles are themselves U-shaped. In case of fire, it is advantageous if the cover profile or profiles consist entirely or partially of a foaming material.
Exemplary embodiments of the invention are illustrated in the drawings and will be described in greater detail hereafter. In the figures:
In
By way of a corner connection of perpendicular sash spars 5, 6 to an upper horizontal sash spar 7, the profile composite forms the at least U-shaped sash 2. A planar element 8 such as an insulating glass pane or a fire protection glazing or a metal or plastic plate is inserted into the sash 2. The sash 2 and the planar element 8 form the leaf together. Moreover, the concept of the “window” is also to be understood in the scope of this description and the claims as a fixed glazing comprising a planar element in a frame 3.
The frame 3 of the door 1 is also U-shaped here and has a horizontal frame spar 9 and two vertical frame spars 10, 11.
The sash 2 and/or the frame 3 can alternatively also be designed as circumferentially closed and can have further lower horizontal spars.
Individual ones or all of the frame spars and/or sash spars have a main profile 300 (frame) or 400 (sash) having a substantially U-shaped cross section.
The main profile 300 and/or 400 can respectively be formed in one piece or multiple pieces as a composite profile. A one-piece variant of the main profile 300, 400 is shown in
Initially, the one-piece variants of the main profile 300, 400 from
According to
The transverse leg 14 forms a base web of the U-shaped main profile 300, 400 and the short leg 12 and the long leg 13 form two parallel longitudinal webs of the U-shaped main profile. According to
The long leg 13 of the main profiles 300, 400 is longer than the short leg 12 in a direction perpendicular to the main extension direction X (see
The transverse leg 14 of the sash 2 lies in the sash 2 (
The long leg 13 of the main profile 400 of the sash 2 protrudes with a free end 15 beyond the transverse leg 14.
A glazing bead groove 16 for fixing a glazing bead 17 is formed outward toward the rabbet space F1 on the transverse leg 14 of the main profile 300, 400. A seal groove 18 for arranging a seal 19 between the planar element 8 and the long leg 13 is provided at the free end 15 of the long leg 13 on the side oriented toward the planar element 8 (see in this regard also
Both the short leg 12 and also the long leg 13 of the main profile 300, 400 have function contours 20, 21 respectively arranged on the short leg 12 and also on the long leg 13, in particular entirely or partially protruding therefrom, on the inner sides thereof facing toward one another. These function contours 20, 21 are preferably formed as multi-function contours, which fulfill/implement not only one but rather multiple functions.
The multifunction contours according to
It is advantageous if the function contours 20, 21 form at least two of the above-mentioned grooves a) to c). They particularly preferably each form three or even more of the function grooves or at least parts of this groove/these grooves.
For this purpose, the function contours 20, 21 respectively comprise at least one transverse leg 23 or 24, which protrudes perpendicularly from the short leg 12 or the long leg 13, respectively (see also
A parallel web 25, 26 is formed in each case at the respective end of these transverse legs 23, 24, which extends parallel to the actual short leg 12 or the long leg 13, but is shorter than these legs. Overall, the respective transverse leg 23, 24 and the parallel web 25, 26 essentially form a T shape in cross section.
In this manner, the short leg 12 or the long leg 13 and the one transverse leg 23 or the other transverse leg 24 and the one parallel web 25 or the other parallel web 26 respectively form the corner connector receptacle groove 20a, 21a.
The one edge of corner connectors 4 is inserted into each of the corner connector receptacle grooves 20a, 21a. It is advantageous that the two corner connector receptacle grooves 20a, 21a are dimensioned equally such that identical corner connectors 4 are insertable therein, as this simplifies the installation of the frame (frame and sash 3, 2).
The other edges of the two corner connectors 4 engage in further corner connector grooves 28a, b, which are delimited by short holding webs 29, 30 protruding from the transverse leg 14, the transverse leg 14, and the short leg 12 or the long leg 13, respectively.
The fastening grooves 20b and 21b are formed by the parallel webs 25, 26 and the angled webs 31, 32 formed thereon on the sides facing toward one another.
The parallel webs 25, 26 and the angled webs 31, 32 thus each form fastening grooves 20b, 21b open toward a rabbet space F2 toward the frame 3.
These fastening grooves 20b, 21b are preferably not designed as threaded grooves for the rotating fixing of threaded elements. Rather, they are preferably designed for fixing fastening elements preferably acting in an interlocking and/or frictional manner, which are fixable by a linear movement in the fastening grooves 20b, 21b. For this purpose, the fastening grooves 20b, 21b are U-shaped and are each open toward the rabbet space F2 toward the frame 3. This facilitates the insertion of the fastening elements into the fastening grooves 20b and 21b. Preferably used fastening elements for the fastening grooves 20b, 21b will be described in greater detail hereafter. The fastening grooves 20b, 21b preferably have catch means such as one or more undercuts, which can interact with corresponding catch means such as one or more catch edges.
The receptacle grooves 20c and 21c are used to accommodate the preassembly web 22, which is arranged between the receptacle grooves 20c and 21c and connects them over the length of the main profile 300 or 400 like a bridge and also in the Z direction in sections or preferably continuously. The preassembly web can extend in the Z direction continuously over the entire length of the main profile 300, 400 or can consist of individual parts, which are each only a few centimeters long and are placed at intervals, for example.
The preassembly web 22 is guided so it is displaceable in the receptacle grooves 20c and 21c in the main extension direction Z (see
The receptacle grooves 20c and 21c are formed as preferably undercut grooves, which are open on sides facing toward one another—in a direction parallel to the transverse leg 14.
The preassembly web 22 has a middle web 22a and interlocking contours 33, 34 at the two ends of the middle web 22a, using which it is insertable into the receptacle grooves 20c, 21c and displaceable therein. The interlocking contours 33, 34 are therefore preferably designed corresponding to the cross section of the receptacle grooves 20c, 21c and therefore they engage with little play therein, such that the preassembly web 22 is displaceable in the receptacle grooves 20c, 21c (perpendicularly to the image plane of
In each of
However, there are also several differences, which will be explained hereafter.
The main profile 300 or 400, respectively, of
The main profile 300, 400 of
However, the transverse leg 14 of the main profiles 300, 400 of
In this case, at least one insulating web 39 (
The at least one insulating web 39 made of plastic can optionally alternatively have a metal main structure or individual metal webs in the plastic, which form bridges between the short leg 12 and the long leg 13 and in this manner optimize the statics (see in this regard by way of example EP 1 138 864 B1 of the same applicant and
The short leg and the long leg 12, 13 according to
The long leg 13 also protrudes beyond the transverse leg 14 with one free end 15 or two free ends according to
The corner connector receptacle grooves 20a, 21a can also be used for accommodating fire protection strips having cooling effect, in particular in the regions of the main profiles 300, 400 adjoining the corner connectors.
Both the short leg 12 and also the long leg 13 have the function contours 20, 21 on the inner sides thereof facing toward one another. These function contours 20, 21 are also preferably formed according to
Both the corner connector receptacle groove 20a for accommodating the corner connectors 4 and also the receptacle groove 20d for accommodating the cooling strips 65 are each formed in this case in the hollow chambers 37, 38 of the short leg 12 or the long leg 13, respectively. Cooling strips 65 are those strips which can absorb a certain amount of fire heat or energy and/or can actively cool in case of fire. They can consist of a molded body having a high heat capacity, for example, of concrete. However, they can also consist of one or more molded bodies which contain heat-binding hydrophilic adsorbent (see, for example, DE 197 00 696 C and DE 4443762 A1). The receptacle grooves 20d, 21d for respectively accommodating a cooling strip 65 can be seen in
For this purpose, the functional contours 20, 21 each in turn comprise (see, for example,
A parallel web 25, 26 is formed at the respective end of these transverse legs 23, 24, respectively, which extends parallel to the inner profile 12 or the outer profile 13 but is shorter than these. Overall, the respective transverse legs 23, 24 and the parallel webs 25, 26 essentially form a T shape in cross section. In this manner, the inner profile 12 or the outer profile 13 and the one transverse leg 23 or the other transverse leg 24 and the one parallel web 25 or the other parallel web 26 respectively form the corner connector receptacle groove 20a, 21a.
The edges of a total of two corner connectors 4 are in turn inserted into each of the corner connector receptacle grooves 20a, 21a (see
The edges of the two corner connectors 4 engage in the further corner connector grooves 28a, b, which are delimited by short holding webs 29, 30 formed in the hollow chambers 37, 38, the transverse leg 14, and the short leg 12 and the long leg 13.
The fastening grooves 20b and 21b are delimited by webs 40, 41 of the short leg 12 and the long leg 13 and are partially formed with them, which delimit the hollow chambers 37, 38 toward the transverse leg 12 or on the sides facing toward one another, and angled webs 31, 32 formed thereon on the sides facing toward one another.
In this manner, the further (parallel) webs 40, 41 and the angled webs 31, 32 each form the fastening grooves 20b, 21b open toward the further rabbet F2 toward the frame. These fastening grooves 20b, 21b are preferably not designed as threaded grooves for the rotating fixing of threaded elements. Rather, they are preferably designed for fixing fastening elements preferably acting in an interlocking and frictional manner, which are fixable by a linear movement in the fastening grooves 20b, 21b. However, the fastening grooves 20b, 21b are also formed for this purpose in
The receptacle grooves 20c and 21c are in turn used to accommodate the preassembly web 22, which is arranged between the two receptacle grooves 20c and 21c and continuously connects them. The preassembly web 22 is formed as shown in
In
Because the preassembly web 22 has been removed after the application of the miter cuts (which is possibly preceded by powder coating of the main profile 400), the main profile is open between the short leg 12 and the long leg 13 on the side facing away from the main leg 14. This is the side lying toward the rabbet F2, i.e., toward the frame 3.
One difference is that in the main profile 400 of the sash, a longer web (the free end 15) is provided on the outer profile 13 than on the main profile of the frame 3. This longer web is used to cover the planar element 8 in the edge region and holding it around the seal 19 toward the planar element 8 (
A further seal 67, to seal the rabbet F2, is arranged on each of these further free (protruding) ends 15a on the inside toward the rabbet F2. The contours of the main profile 300 of the frame 3 and the main profile 400 of the sash 2 are identical toward the rabbet F2 but are located diagonally opposite to one another.
A second difference between the main profiles 300 and 400 of the frame 3 and the sash 2 is that the short leg 12 and the long leg 13 are located diagonally opposite to one another on the installed window or on an installed door (see
It can be desirable and can be considered to be advantageous if it is possible to again close the open side of the U-shaped main profile 300, 400 toward the rabbet F2 between the frame 3 and the sash 3 (for example, after the removal of the preassembly profile 22) using a visually appealing element, and advantageously to form a dust and vision protection toward the rabbet F2 in a simple manner. Moreover, a more visually appealing view toward the rabbet F2 is desired than offered by the preassembly profile 22.
It is therefore advantageous if, as illustrated in
The cover profile 42 preferably lies completely between the short leg 12 and the long leg 13 and terminates flush with these two legs 12, 13 on the side facing away from the transverse leg 14. The cover profile 42 aligns there with two transverse webs 35, 36, with which it defines a or the visible plane E1. The free space or gap between the short leg 12 and the long leg 13 is thus simply covered in a visually appealing manner. This is the primary function of the cover profile. According to one preferred variant, it is not an element statically supporting and elevating the stability of the main profile 400, 300 in a noticeable manner between the ends of the short leg 12 and the long leg 13 facing away from the transverse leg 14. Rather, it primarily has the function of a visual cover, a dust and dirt safeguard, and possibly a fire protection function, the latter in an optional embodiment and design which will be explained in greater detail hereafter. Alternatively, however, it is also conceivable that the cover profile connects the two legs 12, 13 statically as a (thermally) insulating element.
It is advantageous that the short leg 12 and the long leg 13 end in the region of the transverse webs 35, 36 at the ends of the parallel webs 25, 26 externally at the common plane El parallel to the transverse leg 14 (Y direction).
The cover profile 42 of
The catch feet 43, 44 can have greatly varying geometries. They can consist, for example, of solid material and can have outer catch edges (
The cover profile or profiles 42 can moreover be formed in one piece or multiple pieces. Moreover, they preferably consist of plastic (such as PVC, PP) or a fire protection material or a combination of these two materials. If they consist of a combination of these two materials, they preferably have a U-shaped fire protection bridge 47, with which the catch feet 43, 44 are associated, and a transverse web or cover leg 45 connecting them, which forms a part of the cover profile 42. The cover profiles 42 are preferably composed and designed such that required pieces can be cut off from them easily, for example, using scissors.
The cover leg 45 is preferably enclosed or covered on one of its sides or on both sides and/or at least in corner regions using fire protection material, and therefore fire protection regions 48 are formed (
As stated, in this manner a preferably planar surface toward the inside toward the rabbet F2 is implemented in a simple manner. In the longitudinal direction transverse to the image plane of
The region of a lock assembly 50, which can be installed on the main profile 400 in a manner to be described hereafter, is preferably not covered by the cover profile.
One of the profile clamps 51 is depicted in
The main leg 51a is dimensioned sufficiently long in this case that it overlaps the interval between the fastening grooves 20b, 21b. The profile clamps 51 are preferably formed from sheet steel. This sheet steel is preferably very thin and preferably has a thickness between 0.5 and 1.5 mm. It is formed into a stamped/bent part. Because the profile clamps 51 consist of steel, they can be designed very stably. They are locked spaced apart from one another into the fastening grooves 20b, 21b and cut into the light metal of the main profile 300 or 400 therein. In this manner, they stabilize the main profile 400 of the sash or the main profile 300 of the frame, respectively, and hold the short leg 12 and the long leg 13 at a distance in a defined manner.
The profile clamps 51 are first locked on when possible miter cuts have been carried out on the main profile 300 or 400 and when the preassembly web 22 has been removed. In this manner, they cannot damage a saw or a saw blade during the sawing of the miter cuts. On the other hand, they have a very stabilizing effect on the profile, without noticeably increasing its weight. Because the longitudinal legs 51b, 51c of the profile clamps 51 are themselves U-shaped, it is even possible to also place the cover profile 42 on the profile clamps 51, when they have been fixed on the main profile 400 or 300, respectively, the cover profile then lying above the profile clamps 51 in the region thereof, and therefore they are not visible in the installed state.
The profile clamps 51 are locked on (like the cover profiles 42), preferably in the X direction perpendicular to the transverse leg 14.
At least one of the profile clamps 51 is preferably attached in each case on the main profile 400 of the sash 2 where a fitting part, by way of example and preferably, a lock assembly 50, is to be attached. On the sash, this is typically a lock assembly 50 comprising a lock 54 with cylinder and one or more movable bolt(s). The profile clamps 51 or one of the profile clamps 51 is arranged vertically directly below the lock assembly 50, and therefore it is additionally secured and vertically fixed on the main profile 400.
A preferred lock assembly 50 is shown in
The carrier element 59 is preferably designed as a profile section. In particular, it is a profile section of a light metal profile, in particular of an aluminum profile. It is theoretically also conceivable to form the carrier element not as a profile section but rather as a stamped/bent part or the like or as a cast part. The screw 58 can be screwed into the carrier element 59. It can also have a central screw borehole 60 for this purpose. The carrier element 59 (see
The longitudinal legs 59b, 59c are in turn spaced apart from one another such that they can engage in the fastening grooves 20b, 21b of the main profile (400 or 300). They are preferably not directly locked therein. Rather, they are designed for the purpose of engaging in securing clips 61, 62. For this purpose, the securing clips 61, 62 have catch edges 63, 64 at both ends thereof. These catch edges 63, 64 are provided at both ends in the securing clips 61, 62, which are U-shaped in cross section. Using them, the securing clips 61, 62 can be preinstalled on the carrier element 59. After the fastening of the fastening clips 61, 62, the entire lock assembly 50 can be inserted into the fastening grooves 20b, 21b, which in turn hold the lock assembly 50 in a locking manner (for example, like a so-called “hawk mouth”).
The securing clips 61, 62 preferably consist of plastic. In this manner, greatly varying devices, in particular the preinstalled lock assembly 50 or other fitting parts or the like, can be fixed on the main profile 400 or 300 using the securing clips. In this manner, the lock assembly 50 comprising the lock 54 is securely fastened in a simple manner on the main profile 400 of the sash 2. In addition, the lock assemblies 50—as already described above—are fixed and/or secured against slipping using the profile clamps 51 on the main profile 400.
The carrier element 59 or the carrier elements can also be used for the simple and preferably tool-free fixing of another element or an assembly other than a lock assembly on the respective main profile 300, 400. Other fitting parts can thus be fastened in a simple and preferably tool-free manner using them.
The main profile 400 (or an associated main profile 300 (not shown here)) of
The variant of the main profile 400 (or an associated main profile 300 (not shown here), respectively) of
Multifunction contours 20, 21 are also provided in each case on both the short leg 12 and also on the long leg 13 of the main profile 300, 400 respectively on the inner sides facing toward one another in
The main profile 400 of
A removable preassembly web 22 is not provided according to
Because the main profile 400 is formed as an extruded profile, the recesses 69 are only stamped or cut out after the extrusion. Therefore, a transverse leg 66′ continuous in the main extension direction initially connects the short leg 12 and the long leg 13 after the extrusion. Only then are the recesses 69 introduced and only the transverse webs 68 remain of the transverse leg.
The transverse web or webs 68 have an extension direction perpendicular to the direction Z and an extension in the direction Z, wherein Z is the main extension direction of the main profile 300, 400. The transverse webs 68 are spaced apart from one another in the main extension direction Z of the main profile 300, 400.
It is particularly advantageous if the recesses 69 have a relatively large surface area, and are preferably larger than the material area of the transverse webs 68. The larger the recesses 69 are, the better fittings, for example, may be installed.
The transverse webs 68 extend in the main extension direction Z of the main profile 400 and perpendicularly thereto in a connection direction, which is the direction in which the respective transverse web 68 connects the two long legs (the long leg and the short leg here) to one another. The thermal insulation properties of the main profile or of a window or a door, respectively, are advantageously improved in this region by the recesses 69.
However, it is particularly advantageous that fittings, for example, hinges or lock cylinders, may be integrated easily and thus advantageously into the main profile 400 through the at least one recess 69 or may be installed thereon, without the main profile 400 having to be machined before the installation of a fitting.
The recesses 69 preferably have an extension between 100 mm and 200 mm, particularly preferably between 125 mm and 175 mm, in the main extension direction Z.
The recesses 69 (and accordingly the transverse webs 66) preferably extend over the entire distance between the long leg 13 and the short leg 12. They extend here between the ends of the function contours 20, 21 of the long leg 13 and the short leg 12 facing toward one another. This is particularly preferable and facilitates the installation of fittings in a special manner. Alternatively, however, the recess 69 can also extend over only up to 75%, in particular up to 50% of the width of the transverse web 68.
The transverse webs 68 preferably have an extension of 15 mm to 55 mm, particularly preferably between 30 mm and 45 mm, in the main extension direction X.
These dimensions are preferably achieved at at least one or more of the recesses 69. The finished main profile 300, 400 may thus be further processed well, thus each may be miter cut for the frame or sash 2, 1, and fittings may thus be installed particularly well in the region of the recesses 69.
The above features, which have been explained for the main profile 400 of
The transverse leg 14 of the main profile 300, 400 of
This insulating web 70 preferably connects the function contours 20, 21 of the short leg 12 and the long leg 13 to one another. It (and possibly the metal reinforcement(s) in its region) has/have recesses 71. The insulating web is thus reduced to transverse webs 72, between which the recesses 71 are formed. The recesses 71 and the transverse webs 72 are in turn preferably formed similarly with respect to the dimensions thereof to the recesses 69 of
The above features which have been explained for the main profile 400 of
