Abstract
As part of the kitchen fixtures, glass ceramic cooking surfaces are subject to fashionable design trends. The market thus now calls for glass ceramic cooking surfaces with a circumferential flat polished bevel. These glass ceramic cooking surfaces are especially sensitive to shock and thus to breakage at their edges.
The invention provides for special edge protection, which protects the thin edge of the glass ceramic cooking surface from direct mechanical shock stress from the side and/or from above. A basic embodiment with circumferential edge protection that consists of a permanently elastic layer, which encases the front of the edge and its lower side and which is formed from a frame that is made of hard material, is suitable for installation on a sill plate. In the case of another basic embodiment for installation in a cutout in the sill plate, the glass ceramic cooking surface, which is provided with the permanently elastic layer on the lower side and a supporting frame that is attached to it, is installed recessed in the cutout, whereby the encasing of the front with the permanently elastic layer is done in the installed state.

Description
CA 0222239~ 1997-11-27 Arrangement for In~talling Gla~ Cer~mic Cooking 8urfa¢e~ in an Edge Area That Tapers to a Thin Edge at a Sill Pl~te The invention relates to an arrangement for installing glass ceramic cooking surfaces on a sill plate with a glass ceramic plate that has an edge area which tapers to a thin edge in the form of a circumferential polished bevel.
As part of the kitchen fixtures, glass ceramic cooking surfaces are subject, like the kitchen furniture itself, to fashionable, design trends that attempt to produce aesthetically pleasing forms. Thus, the market now calls for glass ceramic cooking surfaces with special edge designs that have edge areas which taper to a thin edge, preferably glass ceramic cooking surfaces with a round-circumferential flat polished bevel.
There are already glass ceramic cooking surfaces on the market that are beveled at the edges and are installed on the latter in a cutout in the kitchen sill plate without any edge protection.
While known mirror glass that is equipped with round-circumferential flat polished bevels for the associated special aesthetics requires no further edge protection except for shipping protection since it can be assumed that this mirror glass --suspended on the wall or incorporated into furniture -- will not be exposed to any m~r-h~n;cal loads, in practice glass ceramic cooking surfaces are exposed to major mechanical loads which, without suitable edge protection, create a considerable risk of breakage.
In particular, lateral shocks to the edge which, in the known case, is open and relatively thin, e.g., when pots are moved around on CA 0222239~ 1997-11-27 the sill plate, create, with this type of glass ceramic cooking surface, a considerable risk of breakage, possibly leading to injury for the user, although glass ceramic cooking surfaces without such edge mach;n;ng and that are installed in suitable frames can now withstand the above-mentioned loads.
The object of the invention, starting from the above-mentioned arrangement, is to configure said arrangement in such a way that, on the one hand, the aesthetics of the cooking surfaces that are beveled on the edge are still ensured and, on the other hand, an open edge is avoided.
This object can be accomplished according to the invention with a layer arrangement that is made of a permanently elastic material which encases the front of the edge and the lower side of the beveled edge area, whereby the arrangement, which is designed in the shape of a frame, is made in such a way that the edge is not exposed to direct mechanical shock stress from the side and/or from above.
Because of the edge protection measure according to the invention, the risk of breakage of the beveled glass ceramic cooking surface is significantly reduced, and the drawbacks that are described in connection with their known arrangement are avoided to a large extent, without their desired aesthetic impact being impaired.
A glass ceramic cooking surface with a special edge design is known in the art from DE 43 04 370 C2. The known case is a cooking surface that is chamfered on one edge, i.e., has a bevel that runs from the top to the bottom, which is encased by an inclined section CA 0222239~ 1997-11-27 of an edging frame with an intermediate sealing contour. Using a clamping device, the two bevels can be pressed very tightly together to provide a very tight connection between the glass ceramic cooking area and the edging frame. The visible ledge of the edging frame and the upper edge of the cooking surface are in this case flush with one another when installed, with the chamfered bevel being completely covered, wheréby the visible ledge can also be placed somewhat lower.
In addition, a cooking area glass ceramic plate with a bevel in the edge area is known from DE 32 27 058 A1, whereby an elastic edge protective element that encases the cooking area edge adjoins the end of the bevel. In this known arrangement, the only purpose of the bevel is to protect the cooking area edge from breakage, i.e., the bevel itself therefore serves as edge protection. It is intended to protect the edge from damage by shock stress. The purpose of the bevel is therefore ultimately to improve the edge area mechanically by virtue of the fact that the usually vertical edge of the glass ceramic plate from which cracking may arise as a result of muscling-out or the like is broken up.
Just as the already considered DE 43 04 370 C2, the previously mentioned DE-OS thus deals with a bevel that is relatively steep and has nothing to do with a polished bevel. This is also shown in the fact that the edge protective element can overlap the bevel, which is at odds with a purely optically aesthetic bevel, i.e., an aesthetically pleasing bevel.
The edge-side polished bevel according to the invention is more than a simple edge bevel. In the case of a polished bevel, CA 0222239~ 1997-11-27 the edge area very gradually tapers at a shallow angle to a very thin edge. In terms of mechanics, this polished bevel leads to a weakening of the plate, and therefore the risk of damage also increases since the glass ceramic plate is designed to be thinner over a comparatively large edge area. The known bevel and the bevel of the cooking area-glass ceramic plate according to the invention therefore have completely different objects. What is important in the invention is to protect the thin edge of the polished bevel while preserving the aesthetic impact of the bevel, an object that is not set in the known case.
In this known case, the type of glass ceramic cooking areas that is described above does not exist. Since it is completely covered when installed, the chamfered edge serves, unlike the beveled cooking surfaces, not the above-described aesthetic purposes, but rather has exclusively an attaching function.
Special advantages with respect to the risk of breakage at minimized expense are achieved corresponding to a further development of the invention if the layer thickness of the front permanently elastic layer is between 0.3 and 0.7 mm and preferably 0.5 mm.
For the protection of the thin edge of the beveled edge area, there are various possible concepts. According to an embodiment of the invention, a concept exists whereby the glass ceramic cooking surface is provided with circumferential edge protection by encasing the permanently elastic layer with a hard, energy-distributing, impact-resistant layer and can be installed on the latter as a unit in a cutout in the sill plate. As a result, CA 0222239~ 1997-11-27 shipping protection is also advantageously ensured by the installation-edge protection if the hard layer is attached immediately after the glass ceramic cooking surfaces is machined.
In this case, it is not absolutely necessary to place the unit on the sill plate. It is also conceivable to provide a recessed, round-circumferential section in the cutout of the sill plate on which the cooking surface rests flush with the sill plate surface.
To ensure unity of the cooking surface, the permanently elastic layer and the hard layer are preferably tightly connected together, preferably glued together according to a simple design.
The permanently elastic layer can be made from various materials. It can consist of, e.g., a silicone adhesive that is applied as a layer, which can be marketed together with glass ceramic materials for cooking surfaces. There may also be advantages with respect to production, however, if the permanently elastic layer consists of a rubber profile, preferably silicone rubber, that is vulcanized directly onto the glass ceramic cooking surface.
Since it is especially advantageous from the standpoint of production and installation it is especially advantageous if, according to a further development of the invention, the hard layer is formed by a round-circumferential profile that is made of metal or plastic.
To minimize shock stress from above, it is advantageous if, according to an additional embodiment of the invention, the hard layer extends above the permanently elastic layer on the front of the edge by a specific amount, preferably 0.5 mm. A shock stress CA 0222239~ 1997-11-27 from above then strikes the upper edge of the hard layer first, in particular the profile.
According to another embodiment of the invention, another concept of edge protection consists in the fact that the glass ceramic cooking surface is provided only with the permanently elastic layer on the lower side and a supporting frame attached thereto, recessed in a cutout of the sill plate with the supporting frame, and the encasing of the front of the edge with the permanently elastic layer is done after it is installed. An arrangement that is designed in this way is especially advantageous for flush installation into the cutout of a sill plate.
In this case, according to a further development of the invention, it is especially advantageous with respect to installation if the permanently elastic layer is formed on the front of the edge by an adhesive layer, preferably made of a silicone adhesive, that fills the joint between the edge and the sill plate cutout.
For installation inside the cutout of the sill plate, various options are open to one skilled in the art. A very simple kind of installation that involves no visible frame and is thus economical is possible if, according to an embodiment of the invention, the sill plate cutout has a round-circumferential shoulder on which the glass ceramic cooking surface rests with the leg of the supporting frame that is fastened to the lower side of the tapered edge area.
According to another further development, the installed arrangement is aesthetically pleasing if an installation-subframe is attached to the sill plate cutout with an upper leg that is designed as a CA 0222239~ 1997-11-27 visible frame and that rests on the sill plate and a lower leg that carries the supporting frame.
Corresponding to the first concept, it is advantageous for minimizing shock stress from above if, when installed, the edge of the glass ceramic cooking surface ends with the highest projection on the sill plate side, and preferably is arranged a certain smaller distance below.
Other configuration features and advantages~of the invention are indicated in the description of the embodiments that are depicted in the drawings.

Thus, the market now calls for glass ceramic cooking surfaces with special edge designs that have edge areas which taper to a thin edge, preferably glass ceramic cooking surfaces with a round-circumferential flat polished bevel.
There are already glass ceramic cooking surfaces on the market that are beveled at the edges and are installed on the latter in a cutout in the kitchen sill plate without any edge protection.

In particular, lateral shocks to the edge which, in the known case, is open and relatively thin, e.g., when pots are moved around on CA 0222239~ 1997-11-27 the sill plate, create, with this type of glass ceramic cooking surface, a considerable risk of breakage, possibly leading to injury for the user, although glass ceramic cooking surfaces without such edge mach;n;ng and that are installed in suitable frames can now withstand the above-mentioned loads.

The visible ledge of the edging frame and the upper edge of the cooking surface are in this case flush with one another when installed, with the chamfered bevel being completely covered, wheréby the visible ledge can also be placed somewhat lower.
In addition, a cooking area glass ceramic plate with a bevel in the edge area is known from DE 32 27 058 A1, whereby an elastic edge protective element that encases the cooking area edge adjoins the end of the bevel. In this known arrangement, the only purpose of the bevel is to protect the cooking area edge from breakage, i.e., the bevel itself therefore serves as edge protection. It is intended to protect the edge from damage by shock stress. The purpose of the bevel is therefore ultimately to improve the edge area mechanically by virtue of the fact that the usually vertical edge of the glass ceramic plate from which cracking may arise as a result of muscling-out or the like is broken up.

In terms of mechanics, this polished bevel leads to a weakening of the plate, and therefore the risk of damage also increases since the glass ceramic plate is designed to be thinner over a comparatively large edge area. The known bevel and the bevel of the cooking area-glass ceramic plate according to the invention therefore have completely different objects. What is important in the invention is to protect the thin edge of the polished bevel while preserving the aesthetic impact of the bevel, an object that is not set in the known case.
In this known case, the type of glass ceramic cooking areas that is described above does not exist. Since it is completely covered when installed, the chamfered edge serves, unlike the beveled cooking surfaces, not the above-described aesthetic purposes, but rather has exclusively an attaching function.
Special advantages with respect to the risk of breakage at minimized expense are achieved corresponding to a further development of the invention if the layer thickness of the front permanently elastic layer is between 0.3 and 0.7 mm and preferably 0.5 mm.

To minimize shock stress from above, it is advantageous if, according to an additional embodiment of the invention, the hard layer extends above the permanently elastic layer on the front of the edge by a specific amount, preferably 0.5 mm. A shock stress CA 0222239~ 1997-11-27 from above then strikes the upper edge of the hard layer first, in particular the profile.
According to another embodiment of the invention, another concept of edge protection consists in the fact that the glass ceramic cooking surface is provided only with the permanently elastic layer on the lower side and a supporting frame attached thereto, recessed in a cutout of the sill plate with the supporting frame, and the encasing of the front of the edge with the permanently elastic layer is done after it is installed. An arrangement that is designed in this way is especially advantageous for flush installation into the cutout of a sill plate.
In this case, according to a further development of the invention, it is especially advantageous with respect to installation if the permanently elastic layer is formed on the front of the edge by an adhesive layer, preferably made of a silicone adhesive, that fills the joint between the edge and the sill plate cutout.
For installation inside the cutout of the sill plate, various options are open to one skilled in the art. A very simple kind of installation that involves no visible frame and is thus economical is possible if, according to an embodiment of the invention, the sill plate cutout has a round-circumferential shoulder on which the glass ceramic cooking surface rests with the leg of the supporting frame that is fastened to the lower side of the tapered edge area.
According to another further development, the installed arrangement is aesthetically pleasing if an installation-subframe is attached to the sill plate cutout with an upper leg that is designed as a CA 0222239~ 1997-11-27 visible frame and that rests on the sill plate and a lower leg that carries the supporting frame.
Corresponding to the first concept, it is advantageous for minimizing shock stress from above if, when installed, the edge of the glass ceramic cooking surface ends with the highest projection on the sill plate side, and preferably is arranged a certain smaller distance below.
Other configuration features and advantages~of the invention are indicated in the description of the embodiments that are depicted in the drawings.
Here:
Fig. 1 shows a beveled glass ceramic cooking surface with round-circumferential edge protection, formed by a metal profile for installation on a sill plate, Fig. la shows a first variant of the embodiment according to Fig. 1 with a profile that extends flat, Fig. lb a second variant of the embodiment according to Fig. 1 with a profile that has an edge bead, Fig. 2 a beveled glass ceramic cooking surface which, with the aid of an installation-subframe, is installed recessed in the cutout of a sill plate, while forming edge protection in the installed state, Fig. 2a a first variant of the embodiment according to Fig.
2 with a sloped visible ledge of the installation-subframe, CA 0222239~ 1997-11-27 Fig. 2b a second variant of the embodiment according to Fig. 2 with a bead-like visible ledge of the installation-subframe, Fig. 3 another embodiment for installing the permanently elastic layer on the beveled glass ceramic cooking surface, and Fig. 4 a beveled glass ceramic cooking surface, which is installed without a frame, recessed, in the cutout of a sill plate, while forming the edge protection in the installed state.
Fig. 1 shows glass ceramic cooking surface 1 that is beveled at its edges with a tapering edge area la and beveled, thin edge lb. The edge of glass ceramic cooking surface 1 is encased by a round-circumferential metal profile 2. In this case, the portion of profile 2 that is laterally higher is designed in such a way that its upper edge 2c ends with beveled edge lb of the cooking surface or preferably projects slightly (e.g., 0.5 mm) so that a shock stress from above strikes only the profile edge.
Metal profile 2, as a preferred embodiment of a hard, energy-distributing and shock-resistant layer, comprises a layer made of permanently elastic material that is between it and the beveled edge area and that also absorbs the shock energy which arises when work is done on the cooking surface.
This layer consists of an adhesive layer 3, preferably made of silicone adhesive, that is attached to the lower side, absorbs shocks from above and, moreover, mainly has the function of attaching glass ceramic cooking surface 1 to metal profile 2. This CA 0222239~ 1997-11-27 adhesive layer 3 has the usual thickness of 1.5 mm, but at least 1 mm.
The lateral protection of cooking surface edge lb is ensured by the fact that a thin adhesive layer 3a is provided between profile leg 2a and the front of edge lb of cooking surface 1.
Tests have shown that, even at a layer thickness of as little as about 0.5 mm, the damping of shock stress from the side is enough to protect the edge of the cooking surface. This adhesive layer 3a, which is thin compared to adhesive layer 3, also has the advantage that profile 2 adjoins cooking surface 1.
Starting from a thickness of glass ceramic plate 1 in Fig. 1 of about 4 mm, the length of section la that tapers to edge lb typically is about 10 to 15 mm with a thickness of edge lb in the range of < 2.5 mm. The length of the lower leg of profile 2, which also ensures mechanical enhancement of the beveled edge area, is determined based on the length of the tapered section.
Circumferential profile 2 with circumferential adhesive layers 3, 3a ensures effective edge protection against shock stresses that commonly occur when glass ceramic cooking surfaces are used.
If profile 2 is attached with permanently elastic layers 3, 3a -immediately after glass ceramic cooking surface 1 is machined, shipping protection during shipping from the manufacturer of the glass ceramic cooXing surface that is provided with edge protection to the site where it is installed is provided at the same time as edge protection in the installed state.
As depicted in Fig. 3, the permanently elastic layer, instead of adhesive layers 3, 3a in Fig. 1, can also be a rubber profile 12 _g_ CA 0222239~ 1997-11-27 that consists of, for example, silicone rubber and that is vulcanized directly onto the edge area of the glass ceramic plate.
Also suitable are molded polyurethane profiles, whose hardness is adjusted in such a way that, on the one hand, deformation is largely avoided, but in the case of shock stresses, the material has an energy-absorbing action like a crush zone. Such profiles are usually produced in an injection-molding form, into which the molded-in edge portion of the glass ceramic cooking surface is first inserted. In this case, the color scheme depends on the designer's wishes.
A thin coating of the glass ceramic cooking surface with a transparent or black tinted rubber-like material, which reduces the above-described shock energy on the cooking surface, is also conceivable.
For the profile, various embodiments are conceivable that are depicted as examples in Figs. la and lb. In this case, Fig. la shows a profile 2a that extends flat, while Fig. lb shows a profile with a pronounced edge bead 2b. Which embodiment is used depends mainly on the kitchen design that is present in each case.
Moreover, the embodiments according to Figs. la and lb are identical to that according to Fig. 1.
As materials for profile 2, 2a or 2b, e.g., aluminum profiles, which are preferably anodized black, are suitable. Also, however, color-varnished high-grade steel profiles or plastic profiles that are made of unbreakable, temperature-resistant material are conceivable.
CA 0222239~ 1997-11-27 The arrangement according to Fig. 1 or Fig. la and Fig. lb is used, in this case, for installation on a kitchen sill plate above a cutout in said sill plate.
Fig. 2 shows another arrangement according to the invention, in which beveled cooking surface 1 is installed recessed in the cutout of sill plate 10. In this cutout, installation-subframe 4 is previously inserted and attached using screws 8. Installation-subframe 4 has an upper leg 4a that is designed as a visible ledge and that rests with its end 11 on the top side of sill plate 10, as well as a lower leg 4b for supporting a supporting frame 5.
In this installation-subframe, the commonly used cooking area design that consists of ceramic cooking surface 1 and is glued over a layer 3 with an upper leg 5a of supporting frame 5 is used and is fastened in the installation-subframe by virtue of the fact that its lower leg 4b is connected to a lower fastening leg 5b of supporting frame 5 using commonly employed fastening means 9.
Then, the joint between installation-subframe 4 and edge lb of beveled glass ceramic cooking surface 1 is filled, while forming an adhesive layer 7, with an adhesive material, preferably a silicone adhesive.
A circumferential foam profile 6 (adhesive strip or sprayed as a sealing bead) is also attached to supporting frame 5, which, when the joint is glued, prevents the adhesive from getting inside and thus ensures cleaner removal of the adhesive joint.
The installation of glass ceramic cooking surfaces in a cutout of a sill plate using an installation-subframe is known in the art from DE 44 34 821 A1. In contrast to the known design of the installation-subframe, the upper leg of the frame is designed as a visible ledge in the use according to the invention and is just wide enough (about 3 to 5 mm) that cutting tolerances are overlapped when the sill plate cutout is machined.
The geometry of the overall arrangement according to Fig. 2 is designed in such a way that edge lb of cooking surface 1 ends with the edge of visible ledge 4a or preferably is arranged somewhat recessed.
Figs. 2a and 2b show other variant embodiments of visible ledge 4a of installation-subframe 4. In the case of the embodiment according to Fig. 2a, visible ledge 4a is designed like a slope;
conversely, in the case of the embodiment according to Fig. 2b, visible ledge 4a is designed like a bead. Moreover, as the identical reference symbols also indicate, the two embodiments are identical to that according to Fig. 2.
In the case of stone or plastic sill plates, designs are also conceivable that make do without visible frames since in these sill plates, precise machining of the cutout edge is made possible by milling. As a result, in contrast to wooden sill plates, a cleaner edge end at the adhesive joint is possible. SCHOTT Information 2/84 shows in Fig. 4c such a flat installation option.
Fig. 4 shows a simplified variant with a frame-less recessed installation of beveled cooking surface 1 in the cutout of a sill plate 10. In this case, the cooking area structure, which consists of cooking ~urface 1, is placed, already glued to supporting frame 5, on a round-circumferential section lOa of sill plate 10. Then, the joint is filled using a silicone adhesive to form a layer 7.
CA 0222239~ 1997-11-27 In this case, supporting frame S is attached in the usual way to the sill plate.
Otherwise, the same reference symbols are similar to the features of Figs. 1-2.
With the previously described arrangements, installation options are shown for glass ceramic cooking surfaces with special edge mac-hining (bevels) which, on the one hand, ensure adequate protection of such edge embodiments and, on the other hand, highlight the special aesthetics of this edge embodiment.
Fig. 1 shows glass ceramic cooking surface 1 that is beveled at its edges with a tapering edge area la and beveled, thin edge lb. The edge of glass ceramic cooking surface 1 is encased by a round-circumferential metal profile 2. In this case, the portion of profile 2 that is laterally higher is designed in such a way that its upper edge 2c ends with beveled edge lb of the cooking surface or preferably projects slightly (e.g., 0.5 mm) so that a shock stress from above strikes only the profile edge.
Metal profile 2, as a preferred embodiment of a hard, energy-distributing and shock-resistant layer, comprises a layer made of permanently elastic material that is between it and the beveled edge area and that also absorbs the shock energy which arises when work is done on the cooking surface.
This layer consists of an adhesive layer 3, preferably made of silicone adhesive, that is attached to the lower side, absorbs shocks from above and, moreover, mainly has the function of attaching glass ceramic cooking surface 1 to metal profile 2. This CA 0222239~ 1997-11-27 adhesive layer 3 has the usual thickness of 1.5 mm, but at least 1 mm.
The lateral protection of cooking surface edge lb is ensured by the fact that a thin adhesive layer 3a is provided between profile leg 2a and the front of edge lb of cooking surface 1.
Tests have shown that, even at a layer thickness of as little as about 0.5 mm, the damping of shock stress from the side is enough to protect the edge of the cooking surface. This adhesive layer 3a, which is thin compared to adhesive layer 3, also has the advantage that profile 2 adjoins cooking surface 1.
Starting from a thickness of glass ceramic plate 1 in Fig. 1 of about 4 mm, the length of section la that tapers to edge lb typically is about 10 to 15 mm with a thickness of edge lb in the range of < 2.5 mm. The length of the lower leg of profile 2, which also ensures mechanical enhancement of the beveled edge area, is determined based on the length of the tapered section.
Circumferential profile 2 with circumferential adhesive layers 3, 3a ensures effective edge protection against shock stresses that commonly occur when glass ceramic cooking surfaces are used.
If profile 2 is attached with permanently elastic layers 3, 3a -immediately after glass ceramic cooking surface 1 is machined, shipping protection during shipping from the manufacturer of the glass ceramic cooXing surface that is provided with edge protection to the site where it is installed is provided at the same time as edge protection in the installed state.
As depicted in Fig. 3, the permanently elastic layer, instead of adhesive layers 3, 3a in Fig. 1, can also be a rubber profile 12 _g_ CA 0222239~ 1997-11-27 that consists of, for example, silicone rubber and that is vulcanized directly onto the edge area of the glass ceramic plate.
Also suitable are molded polyurethane profiles, whose hardness is adjusted in such a way that, on the one hand, deformation is largely avoided, but in the case of shock stresses, the material has an energy-absorbing action like a crush zone. Such profiles are usually produced in an injection-molding form, into which the molded-in edge portion of the glass ceramic cooking surface is first inserted. In this case, the color scheme depends on the designer's wishes.
A thin coating of the glass ceramic cooking surface with a transparent or black tinted rubber-like material, which reduces the above-described shock energy on the cooking surface, is also conceivable.
For the profile, various embodiments are conceivable that are depicted as examples in Figs. la and lb. In this case, Fig. la shows a profile 2a that extends flat, while Fig. lb shows a profile with a pronounced edge bead 2b. Which embodiment is used depends mainly on the kitchen design that is present in each case.
Moreover, the embodiments according to Figs. la and lb are identical to that according to Fig. 1.
As materials for profile 2, 2a or 2b, e.g., aluminum profiles, which are preferably anodized black, are suitable. Also, however, color-varnished high-grade steel profiles or plastic profiles that are made of unbreakable, temperature-resistant material are conceivable.
CA 0222239~ 1997-11-27 The arrangement according to Fig. 1 or Fig. la and Fig. lb is used, in this case, for installation on a kitchen sill plate above a cutout in said sill plate.
Fig. 2 shows another arrangement according to the invention, in which beveled cooking surface 1 is installed recessed in the cutout of sill plate 10. In this cutout, installation-subframe 4 is previously inserted and attached using screws 8. Installation-subframe 4 has an upper leg 4a that is designed as a visible ledge and that rests with its end 11 on the top side of sill plate 10, as well as a lower leg 4b for supporting a supporting frame 5.
