Knierim GmbH & Co. KG Metal and plastic processing, 34134 Kassel Frame part and wall and/or door element made with it

The invention relates to a frame part of the type specified in the preamble of claim 1 and a wall and/or door element produced therewith.

Wall or door elements of this type preferably have cover plates made of thin sheet metal and are used primarily for the manufacture of toilet, changing or shower cubicles or the like or of cabinets for such cubicles, but sometimes also for the manufacture of simple partition walls in toilet or shower rooms or the like. It is common practice to design the vertical and horizontal frame parts as frame profiles which are provided with receptacles running along their length on their outward-facing front sides into which profiles suitable for various functions can be inserted (DE 36 18 482 A1). These profiles, which can be firmly connected to the frame profiles by snap or screw connections, consist primarily of stop profiles, by means of which door elements made with the frame parts and inserted into the cubicles or cabinets are provided with stops in the closing and hinge areas. Stop profiles are also attached in a corresponding manner to the wall elements which interact with the door elements. This does indeed have the advantage that the frame parts can be used for other purposes without the stop profiles. However, the disadvantage is that the work involved in attaching the stop profiles to the frame profiles is often not reasonable compared to the advantages that can be achieved with neutral frame parts, especially when, for example, a very large number of doors and/or walls are required in the manufacture of shower, toilet and changing cubicles for public swimming pools or similar.

elements must be provided with stop profiles. In addition, the cover plates of the wall and/or door elements usually only extend to the outer longitudinal edges of the frame parts. Therefore, the stop profiles are not only visible from the outside, but also cause annoying discontinuities in the flat outer surfaces formed by the wall and door elements, which are clearly visible in connection with the door gaps in the locking and hinge area. This applies not only in geometric terms, because the stop profiles at least partially protrude or recede from the wall and door plane, but above all in terms of color. While the cover plates are offered in many different colors depending on the customer's wishes, the stop profiles are usually not only made from a different, cheaper material (e.g. PVC) than the cover plates, but also in only a few colors for cost reasons in order to simplify storage. Therefore, comparatively wide stripes in the color of the stop profiles are usually visible between adjacent wall and/or door elements.

In contrast, the invention is based on the object of designing the frame part of the type described at the outset and the wall and/or door elements that can be produced with them in such a way that their manufacture and assembly is significantly simpler and surfaces produced with the wall and/or door elements have only small discontinuities.

The characterizing features of claims 1 and 12 serve to solve this problem.

The invention brings with it the significant advantage that, unlike before, the stop is permanently installed in the frame part or, conversely, the frame part is integrated into the stop system. In terms of costs, this only results in advantages, since extrusion or extrusion tools are comparatively inexpensive and the saved assembly costs are not achieved by others. Finally, it is also a particular advantage that the frame parts can easily be designed and arranged in such a way that they are almost completely covered by the cover plates, so that only small, visually visible discontinuities arise in the locking or hinge area. This applies regardless of whether the cover plates are made of metal sheets or plastic or laminated materials (HPL).

Fig. 11 and 12 each show a horizontal section on an enlarged scale through the locking or hinge area of an arrangement made from two wall elements and a door element of the second embodiment.

The frame 1 for a door element shown in Fig. 1 is rectangular and composed of frame parts 2 and 3 according to the invention, each of which is also shown in section. Alternatively, a square frame could of course also be provided. In this case, the vertical frame parts 3 shown in Fig. 1, which are parallel to one another, form the lateral frame parts and the horizontal frame parts 2, which are also parallel to one another, form the lower frame parts.

or upper limits of the frame 1. The frame parts 2 are narrower than the frame width by twice the width of the frame parts 3 and, as shown in Fig. 1, are arranged between the lower and upper ends of the frame parts 3 in such a way that they abut against the rear sides of the frame parts 3 along vertical abutting surfaces 4 and 5. 5

According to Fig. 1 and 2, the frame parts 2 preferably consist of hollow profiles with square cross-sections. The hollow profiles have continuous cavities and guides 7 formed on an end face 6, which are not of any further interest here. The frame parts 2 are also provided with two opposite, parallel side faces 8 and 9, which border on the broad sides of the frame 1 and are intended for the attachment of cover plates, as well as with a further end face 10, which is opposite the end face 6. The end and side faces 6, 8, 9 and 10 are otherwise smooth and flat. The frame parts 2 are preferably made from plastic by extrusion or from aluminum by extrusion.

According to Fig. 1 and 3, the frame parts 3 consist essentially of a frame profile 11, preferably designed as a hollow profile, and a stop profile 12 made in one piece with it. While the frame profile 11 has essentially the same shape as the frame part 2, with the exception of the guides 7, the stop profile 12 is designed depending on the door stop desired in the individual case. Fig. 3 shows a stop profile 12 that is particularly suitable for rebated doors with a rebate 14 that runs the entire length of the frame part 3. The rebate 14 is attached to a front face 15 of the frame part 3 and is essentially formed by a stop part 16 that projects perpendicularly to the face 15 and is provided on an inner side with a continuous groove 17 intended to accommodate a sealing element. The frame parts 3 are further provided with a locking groove 20 or 21 running through their longitudinal direction on two opposite, parallel side surfaces 18 and 19, which border on the broad sides of the frame 1 and are intended for the attachment of cover plates, the locking groove 20 preferably being arranged in the immediate vicinity of the front side 15 and the locking groove 21 preferably being arranged in the immediate vicinity of the outer end of the stop part 16, so that the two locking grooves 20, 21 practically come to lie on the two outer longitudinal edges of the stop profile 12 and are spaced apart from one another transversely to the longitudinal direction by a distance a (Fig. 3). In addition, the

-5-

Side surfaces 18, 19 are smooth and flat. A further end surface 22 of the frame part 3, opposite the end surface 15, is of no importance here.

The frame parts 3 are manufactured by extrusion from plastic or preferably by extrusion from aluminum, so that a one-piece, combined frame and stop profile provided with the fold 14 is created in one operation.

Fig. 4 and 5 show a door element 24 according to the invention in combination with two wall elements 25 and 26 according to the invention. The door element 24 consists, analogously to Fig. 1, of a frame made with the frame parts 2 and 3 and two cover plates 27 attached to the two broad sides of the frame. These consist of thin sheets of steel, stainless steel, aluminum or the like, which are provided with inwardly extending folds 28 on their lateral (vertical) edges, which are designed in such a way that they fit exactly into the securing grooves 20, 21 when the cover plate inner sides rest on the side surfaces 8, 9 or 18, 19 of the frame parts 2, 3. As a result, on the one hand, the position of the frame parts 3 relative to the cover plates 27 is fixed in the horizontal direction, while on the other hand the sheet metal edges located at the ends of the folds lie in the securing grooves 20, 21 and are thus largely protected against corrosion. As Fig. 5 also shows, the cover plates 27 can be provided with horizontal folds 29 where they lie on the upper or lower frame parts 2, which come to lie on the end faces 10 (Fig. 2) and abut one another there.

The door element 24 is manufactured by first assembling the frame parts 2, 3, which are produced by extrusion or sprucing and cut to the desired length, to form the frame 1 in the manner shown in Fig. 1. The individual frame parts 2, 3 are placed, for example, on the inside of a rear cover plate 27 in such a way that the securing grooves 20, 21 of the frame parts 3 accommodate the associated bevels 28, whereby the position of the frame profiles 3 is fixed to the cover plate 27, while the frame parts 2 rest against the bevels 29 of the cover plates 27 and are thus also fixed. The interior of the frame 1 is then filled, if necessary, with a filler 30 consisting of, for example, an aluminum or cardboard honeycomb or the like, whereupon a front cover plate 27, if necessary after prior

Applying an adhesive, the inner side of the door panel is placed on the frame 1 in such a way that its bevels 28 also enter the corresponding securing grooves 20, 21. This also fixes the position of the front cover plate 27 to the frame 1 during the final gluing process. If the filler 30 consists of a polyurethane foam, for example, the door element is filled with foam through suitable openings after the gluing process. The guides 7 of the frame parts point inwards when assembled, so that they are not visible. In contrast, the end faces 22 of the frame parts 3 are on the inside and the end faces 15 with the folds 14 are on the outside, with the frame parts 3 on the right and left sides in Fig. 1 being rotated by 180° relative to one another, as can be seen from the arrangement of the frame parts 3 of the door element 24 in Fig. 4.

The wall elements 25, 26 (Fig. 4) are manufactured accordingly. They are provided with frame parts on the closing or hinge side of the door formed by the door element 24, which are also each provided with a stop profile 33 with a fold 32 on the vertical side facing the door element 24. The folds 14, 32 can differ slightly from one another depending on whether they are provided on the door element 24 or on an associated wall element 25, 26. The stop profiles 12, 33 arranged in the hinge area, i.e. on the right in Fig. 4, essentially serve the purpose of covering the gap between the elements 24, 26 when the door is closed.

As Fig. 4 further shows, a sealing element 34 is inserted into the groove 17 of the frame part 3 located in the closing area of the door, while the same groove 17 can remain free in the hinge area. Furthermore, in a manner known per se, certain holding elements 35 are inserted in the hinge area into the hollow spaces provided for this purpose in the frame parts 31 for fastening the wall elements 25, 26 to a support rod, to the ground or the like, and the door-side sections 36 of door hinges are inserted into corresponding hollow spaces in the frame parts 3. In addition, as with the door element 24, the two (vertical) frame parts 31 on both sides of the door element 24 are also rotated 180° relative to one another so that the correct opening or stop function is achieved when the door element 24 is opened or closed in the direction of the arrow shown. It is also understood that the wall elements 25, 26 only need to be provided on both (vertical) sides with a frame element 31 each having a fold 32 if between each two

A door element is arranged between successive wall elements.

In a second embodiment of the invention, which can be seen in Fig. 6 to 12, instead of the cover plates 27 made of steel, stainless steel or aluminum sheet, there are those made of a plastic or laminated material (HPL). In Fig. 6, a frame 41 for a wall element is shown, the frame 41 essentially corresponding to the frame 1 according to Fig. 1 and being composed of frame parts 42 and 43 according to the invention.

According to Fig. 6 and 7, the frame parts 42 correspond essentially to those according to Fig. 2. They differ from these only in that their side surfaces 44, 45 intended for attaching the cover plates are provided with raised, protruding securing webs 46, 47. The securing webs 46, 47, which are approximately 1 mm high and approximately 2.5 mm wide, run parallel to the longitudinal direction of the frame parts 42 and are expediently continuous over their entire length (Fig. 6), so that they can be molded onto the frame parts 42 during the usual extrusion or extrusion process, depending on the material of the frame parts 42 (plastic or aluminum).

The frame parts 43 according to Fig. 6 and 8 correspond essentially to the frame parts 3 according to Fig. 3. They have a stop profile 49 formed on a frame profile 48 with a fold 50. The frame part 43, like the frame part 42, is manufactured in one piece in an extrusion or extrusion process and differs from the frame part 3 according to Fig. 3 on the one hand by the slightly different shape of the fold 50 or the stop part 49. On the other hand, in contrast to the frame part 3, the frame part 43 is provided with raised, protruding securing webs 53 and 54 on two opposite, parallel side surfaces 51 and 52 bordering the broad sides of the frame 41 and intended for the attachment of cover plates, which can be designed essentially like the securing webs 46 and 47 and are expediently extended over the entire length of the frame parts.

Fig. 9 and 10 show the inside of a cover plate 56 according to the invention. The cover plate 56 has a shape corresponding to the frame 41, here rectangular, and is provided with parallel locking grooves 57, 58 on its long edges and with locking grooves 59, 60 on its short edges. The locking grooves 57 to 60 have a depth

• ft B ·

-8th-

of e.g. approximately 1.5 mm and a width of e.g. slightly more than 2.5 mm, so that they can accommodate the associated securing webs 46, 47 or 53, 54 in the manner of tongue and groove connections completely and perpendicular to their direction of extension with little play. Otherwise, the cover plates 56 are expediently made of a plastic or laminated material, with the securing grooves 57 to 60 being produced e.g. by milling or with the aid of a simple sawing process using a circular saw or the like. As Fig. 9 and 10 show, the securing grooves 57 to 60 expediently extend over the entire height and width of the cover plate 56, so that they cross in the corners (e.g. crossing point 61 in Fig. 9 and 10).

11 and 12 show a door element 63 according to the invention in combination with two wall elements 64 and 65 according to the invention, whereby the door element 63, in contrast to Fig. 4, is only partially shown in two different views, each in the closing area (Fig. 11) and in the hinge area (Fig. 12). The wall elements 64, 65 are manufactured by first assembling the frame parts 42, 43, which are manufactured by extrusion or ramming and cut to a desired length, to form the frame 41 in the manner shown in Fig. 6. The individual frame parts 42, 43 are placed, for example, on the inside of a rear cover plate 56 in such a way that their securing webs 46, 47 and 53, 54 come to rest in the corresponding securing grooves 57 to 60, whereby the position of the frame profiles 42, 43 relative to the cover plate 56 is fixed. The interior of the frame 41 is then filled with a filler 66 if necessary, whereupon a front cover plate 56, possibly after prior application of an adhesive, is placed with its inside on the frame 41 in such a way that its securing grooves 57 to 60 also accommodate associated securing webs 46, 47 or 53, 54. This also fixes the position of the front cover plate 56 to the frame 41 during the final gluing process. The end faces with the folds 50 lie on the outside, with the frame parts 43 analogous to Fig. 4 on the right and left sides in Fig. 6 being rotated by 180° relative to one another, as can be seen from the arrangement of the frame parts 43 of the wall elements 64 and 65 in Fig. 11 and 12.

The door element 63 is manufactured accordingly using the frame parts 42 and further frame parts 69 having folds 68. As shown in particular in Fig. 8 to 12, the folds 68 formed on the frame parts 69 can differ slightly from

-9-

the folds 14 of the frame parts 3 differ, since the door element 63 usually has different folds than the associated wall elements.

The frame parts 43 described with reference to Fig. 8 are assigned to the wall elements 64, 65 and are attached to their (vertical) closing side (Fig. 11) or (vertical) hinge side (Fig. 12). In contrast, the door element 63 is provided with one of the frame parts 69 on both the closing side and the hinge side, analogous to Fig. 4, whereby a stop part 70 forming the fold 68 is preferably provided with a continuous groove 71, which serves to accommodate a sealing element 72 and remains free on the hinge side. As with the wall elements 64, 65, the (vertical) frame parts 69 on both sides of the door element 63 are also rotated by 180° relative to one another. .

As shown in particular in Fig. 8, 11 and 12, at least one of the frame parts of the frame 41 additionally has at least one cover strip running along its length, which serves as edge protection for the relevant cover plate. In Fig. 8, both the side surface 51 and the side surface 52 are provided with such a cover strip 73 or 74, against which the respective end faces of the cover plates 56 come to rest. In a corresponding manner, the frame parts 69 also contain such cover strips 75, 76 (Fig. 11 and 12). The cover strips 73 to 76 are produced like the securing webs 53, 54 when the frame parts 43, 69 are extruded or pressed and consist of webs that protrude 1 mm above the corresponding side surfaces. As shown in particular in Fig. 11 and 12, the cover strips 73, 74 and 75, 76 preferably border directly on the longitudinal edges of the frame parts 43, 69 located in the area of the folds 50, 68. Therefore, on the one hand, the cover plates 56 can be made so wide that, when the door formed by the door element 63 is closed, they completely cover the frame parts 43 and 69 up to the fold 50, 68 and therefore only narrow frame sections not covered by the cover plates 56 are visible on both the closing side and the hinge side. On the other hand, the front sides of the cover plates 56 are covered by the cover strips 73 to 76 and are thereby protected from damage, in particular splintering, which otherwise frequently occurs when, for example, cleaning equipment or the like is hit against the front sides of the door and wall elements. In addition, the cover strips 73 to 76 have the advantage that they cover the horizontally running edges bordering the (vertical) front surfaces.

Cover the securing bars 46, 47 of the frame parts 43 and the corresponding securing grooves 57, 58 of the cover plates 56.

Finally, Figs. 8, 11 and 12 in particular show that the securing webs 53, 54 and cover strips 73, 74 located on opposite side surfaces 51, 52 of the frame parts 43 are each offset relative to one another by a distance b (Fig. 11) which essentially corresponds to the width of the corresponding fold 50. This makes it possible to use cover plates 56 which are identically designed and provided with the securing grooves 57 to 60 at the same points on both sides of the frame 41 by simply arranging them on the front and back of the frame 41 with a lateral offset corresponding to the distance b_. Since in this case the distances between the securing webs 53, 54 arranged on two (vertical) long sides of the frame 41 are always the same, it only needs to be ensured that the distance between the securing grooves 59 and 60 and the side edges of the cover plates 56 is exactly the same as the distance b_ (Fig. 11). A corresponding arrangement could be made with regard to further securing webs 77, 78 on the frame parts 69 and the securing grooves 57, 58 and the upper and lower edges of the frame parts 42.

A corresponding arrangement can be seen from Fig. 3 and 4 with regard to the distances a. As shown in particular in Fig. 4 for the door element 24, the cover plates 27 on both sides of the frame are laterally offset by the distance a and can therefore be designed identically.

Furthermore, Fig. 11 and 12 show that retaining profiles 79 for mounting the wall elements 64, 65 can be inserted into the cavities of the frame parts 43 and/or door hinges 80 can be screwed to the frame parts 3, 69. In addition, the frame parts 69 can be provided with recesses for receiving locks 81 and the frame parts 43 can be provided with recesses for receiving bolts and/or latches of the locks 80.
30

The invention is not limited to the described embodiments, which can be modified in many ways. This applies in particular to the arrangement, shape and size of the described securing webs and grooves. It would also be possible to

more than one securing strip is provided on each side surface of the frame parts 42, 43 and 69 and correspondingly more than one securing groove is provided in the associated edge area of the cover plates 56. It would also be conceivable to provide the securing grooves on the frame parts and the securing webs on the cover plates, although for manufacturing reasons the design described is preferable. It would also be possible to make the securing grooves 57, 58 in particular only as long as the securing webs 46, 47 in Fig. 6. In addition, the frame parts could each be composed of several frame part elements connected to one another by internal fastening means. In the case of wall elements to which no door elements are attached or to which only one side of the door elements is attached, it is also possible to manufacture the frame all around exclusively from the frame parts 2 or 42 according to Fig. 2 or 7 or to provide it with only one frame part 3 or 43. Furthermore, the shape of the fold or the stop parts of the frame parts containing it can be chosen as desired and as appears appropriate for the individual case. In this case, solutions such as those shown in Fig. 4, 11 and 12 are particularly preferred, since in these cases flat gaps are created, separated only by narrow air gaps and possibly thin stop strips (73 to 76), made of a material that repels the material of the cover plates. Finally, it is understood that the individual features can also be used in combinations other than those shown and described.
