GUIDE DEVICE FOR A DRAWER, FURNITURE AND KITCHEN APPLIANCE

Description

State of the art

[0001] In the furniture sector, for example in kitchen furniture and kitchen fittings, or in kitchen appliances such as ovens, devices for the movable or sliding guidance of a drawer element are known. For the horizontally movable guidance of a drawer element in the furniture or kitchen appliance during use, two guide devices, preferably designed as telescopic extensions, are typically provided for the drawer element.

[0002] The connection of the guide device to the rod arrangement must be stable, easy to provide and easy to assemble.

[0003] The prior art includes DE 202018104249 U1, DE 202018000552 U1, DE 102011050987 A1, DE 102015206596 B3, DE 102015206599 A1, WO 2010 / 089553 A1 and EP 3425283 A1. Purpose and advantages of the invention

[0004] The object of the present invention is to provide an improved version of a device, or a piece of furniture and a kitchen appliance, as discussed in the introduction, particularly with regard to aspects of manufacturing, the attachment of the sliding element to the rod arrangement and the quality of the fastening.

[0005] This problem is solved by the independent claims.

[0006] The dependent claims address advantageous variants of the invention.

[0007] The invention relates to a device for guiding a sliding element relative to a rod arrangement, wherein the device is designed to receive the sliding element on the rod arrangement, wherein the rod arrangement has a horizontal web and a vertical web connected to the horizontal web and is designed for arrangement on a side wall inside a piece of furniture or a kitchen appliance, wherein the device comprises a fixed rail attributable to the rod arrangement and an extendable rail that can be coupled to the sliding element and is displaceable relative to the fixed rail, and wherein retaining means of the device are provided by means of which the device can be attached to the rod arrangement.

[0008] The sliding element is typically mounted on both sides of movable rails of the respective guide, with each guide being supported at a common vertical height by corresponding rod assemblies on a right and left inner side wall of the furniture or kitchen appliance. These rod assemblies are located on opposite vertical walls of a receiving space within the furniture or kitchen appliance, such as an oven. The sliding element can be, for example, a drawer in a piece of furniture or a refrigerator, a cooking support such as a baking rack, a baking and / or cooking tray, or a pull-out oven shelf. Typically, for example, in an oven cavity or the oven itself, a rod assembly with vertical and horizontal bars, or a standardized side grid, is present on opposite side walls for mounting the sliding element or the baking and / or cooking tray.

[0009] The rod arrangement can also be referred to as a grid arrangement. The rod arrangement, such as an oven rack made of, for example, a heat-resistant stainless steel material, preferably comprises two or more horizontal bars and two or more vertical bars aligned parallel to each other. In its operating state, the vertical bars are preferably spatially perpendicular, and the horizontal bars are preferably spatially horizontal. The horizontal bars are preferably perpendicular to the vertical bars. The rod arrangement is, for example, grid-like; in particular, such rod arrangements are standard in ovens. Accordingly, two rod arrangements are provided in an interior space of the furniture or kitchen appliance, such as an oven, one on each side of the interior wall of the furniture or kitchen appliance.The horizontal webs and / or vertical webs are preferably formed from a profile such as a web profile, for example a cylindrical round profile and / or a flat sheet metal material.

[0010] The core of the invention lies in the fact that the holding means comprises a holding element present on the fixed rail and attachable to the vertical web, with a gripping section open on one side, which includes a contact surface opposite the open side and a plastically deformable bending tab, so that in a state of the device attached to the rod assembly, the vertical web rests against the contact surface of the gripping section and the bending tab projects laterally from the vertical web, wherein, in order for the gripping section to grasp the vertical web, the bending tab can be brought into a close fit against the vertical web by a bending process, so that the device is fixed to the vertical web in the horizontal direction. With the bending tab until it is grasped, the device is secured to the vertical web.Up to the point where the bending tab makes contact with a section of the outside of the vertical web, where it is not in contact before bending, an at least extensive clamping enclosure of the bending tab on the vertical web is achieved, thus preferably a firm pressing of the bending tab on the outside of the vertical web for fixing the device to the rod arrangement.

[0011] In this way, a fixed and mechanically robust fixing of the guide device to the rod assembly can be provided. In particular, an alternative connection method advantageous to a welded joint is provided. In contrast, the attachment according to the invention does not require a complex and expensive welding machine along with the necessary energy and welding fluid supply. Instead, a simple bending operation at the relevant connection point on the vertical web is advantageously sufficient, which can be carried out with a simple bending tool such as manually operated pliers.

[0012] The bending tab is, for example, tongue-shaped or strip-shaped, or if the holding element consists of a sheet material, is cut free from the material at the front and sides or on both sides and is only connected to it at the back.

[0013] The position of at least one retaining element, preferably several retaining elements, on the fixed rail, viewed along the length of the fixed rail, can be individually determined so that the attachment to the rod arrangement, achievable with the bending tab, is flexible on one or more available vertical webs. This increases the stability of the attachment and simplifies assembly.

[0014] Furthermore, the attachment to the rod arrangement can be flexibly carried out at any vertical height of the rod arrangement, regardless of existing horizontal struts, since the attachment is done solely via the vertical struts.

[0015] Advantageously, an L- or U-shaped gripping section is formed on the holding element. The gripping section, or its receiving area for gripping the relevant section of the vertical web, is appropriately adapted to the outer contour or outer dimension of the vertical web. The at least one holding element is attached to the free longitudinal side of the fixed rail, or the two or more holding elements are preferably attached to a free longitudinal side of the fixed rail offset along its length. In the operating state, the relevant longitudinal side of the fixed rail faces the rod assembly. The unbent gripping section on the device, i.e., in the state before the device is attached to and fixed to the rod assembly, can be open on the front side of the guide or on the back side of the guide to allow gripping of the vertical web during initial assembly or to secure the device.The holding element is threaded onto the vertical web(s). Threading allows the vertical web to come into contact with the mounting side. Then, as a final assembly step, the previously open threading side of the gripping section is closed or locked by bending the tab, and the device is fixed to the rod assembly, preventing movement of the fixed rail in the longitudinal direction of the device.

[0016] According to the invention, the holding means comprise a bearing section on the vertical web and a locking section on the holding element, which, in the state of the device being attached to the rod assembly, interact in such a way that the device is secured against movement in the longitudinal direction of the vertical web. The holding means thus have corresponding locking or detent elements which, in the operating state, ensure that the device, and therefore the guide, is fixed in position on the rod assembly, at least in the vertical direction, and preferably also in the horizontal direction. However, the fixation of the device to the rod assembly is preferably already achieved by the clamping bend of the bending tab and its pressing against the outside of the vertical web. The bearing section can optionally be subsequently or additionally formed on, for example, a standard rod assembly, such as a side rack of an oven, or already during the manufacture of the rod assembly.the side grille can be provided there.

[0017] The bearing section on the vertical web can alternatively also be part of the rod arrangement, i.e., not part of the device; in that case, the holding means of the device are provided solely by the locking section and are designed to be appropriately adapted to the rod arrangement or its bearing section.

[0018] Furthermore, it is advantageous if the bearing section on the vertical web projects beyond the outer shape of the vertical web. This allows for effective anchoring of the device to the rod assembly or along the longitudinal axis of the vertical web. The bearing section preferably projects radially to the longitudinal outer surface of the vertical web, i.e., radially relative to the longitudinal axis of the vertical web. The projecting length of the bearing section is in the millimeter range or on the order of the diameter of the vertical web. The longitudinal outer shape of the vertical web in a typical rod assembly is usually cylindrical. However, the outer shape can also be a different shape, for example, arbitrarily convex, concave, or polygonal.

[0019] Advantageously, the bearing section is designed as an embossed feature on the vertical web. An embossed feature can be added to a finished profile web or incorporated during the web's manufacture. This allows for the creation of a defined shape or form, such as a step, in the vertical web, preferably made of a metal material, in a manufacturing-efficient manner. When a device or fixed rail is attached, the bearing section absorbs dynamic and / or static forces via the retaining element to securely mount the device to the rod assembly. These forces are primarily caused by weight, for example, by the weight of the thrust element, which is attached to the rod assembly via the device.

[0020] According to a preferred variant, the bearing section is designed as an element that is additionally attached to a vertical web of a standard rod arrangement.

[0021] This allows, in particular, the subsequent addition of a vertical support to a standard bar arrangement or a conventional oven side rack with a bearing section. The element is, for example, elongated, like a pin. The element is attached to the vertical support by, for example, welding, soldering, or gluing.

[0022] Another advantage is that the locking section on the holding element has a recess which is designed for a suitable engagement of the bearing section.

[0023] This allows for a space-saving and simple fixed fixing of the fixed rail to the rod assembly. The locking section is preferably designed as a window-like recess in a wall of the retaining element. The retaining element is preferably made of sheet metal. The bearing section and the recess are preferably designed to be compatible so that the bearing section engages snugly, or preferably with minimal play, through the recess.

[0024] An advantageous modification of the invention is characterized in that the holding element is designed as a component with sections oriented at angles to one another. This makes the holding element advantageously connectable to the fixed rail on one side and to the rod arrangement on the other.

[0025] The component consists, for example, of sheet metal, plastic, or solid material. The component is preferably connected to the fixed rail by a rivet, clinch, weld, solder, adhesive, or screw connection. The connection of the retaining element is preferably made to a flat longitudinal side or inner longitudinal side of the fixed rail. In the operating state, the relevant longitudinal side faces the rod arrangement or the side wall of the furniture or kitchen appliance.

[0026] Another advantageous embodiment is that the gripping section has a leg section that is connected to the mounting side.

[0027] Preferably are e.g.Two leg sections are present, connected to each other by the contact side. The gripping section, comprising the contact side and at least one leg section, is preferably L- or U-shaped. In the connected state, the gripping section encompasses the vertical web on two or three sides or circumferentially over, for example, approximately 90 degrees or approximately 180 degrees, preferably in contact, if the vertical web has, for example, a cylindrical outer shape and the bent gripping section fits snugly against the outside of the vertical web.

[0028] According to the invention, the gripping section comprises a leg section, wherein the deformable bending tab belongs to the leg section.

[0029] This allows for easy provision of the bending tab. Furthermore, the lateral proximity of the leg section, including the bending tab, to the vertical web makes it easy to bend the bending tab towards the vertical web or to deform it plastically so that the bending tab tightly grips or locks around the vertical web. To do this, the bending tab simply needs to be bent at its free end towards the vertical web. Advantageously, the holding element or gripping section has, for example, exactly two leg sections that can be brought into contact with the vertical web opposite each other or that come into contact with it laterally. It is particularly preferred if at least one leg section has at least two vertically offset, identical bending tabs.It is advantageous to be able to bend only one bending tab after threading the vertical web onto the gripping section, or to bend both bending tabs towards the vertical web to apply an even higher fixing force.

[0030] The deformable bending tab is located on at least one of the two opposing leg sections. Alternatively, several bending tabs, for example two, can be present on one leg section. According to the invention, one or two bending tabs are provided on two opposing leg sections. The vertical web can thus be advantageously encompassed on both opposite sides by a bent bending tab each. According to the invention, the two bending tabs on the opposing leg sections are vertically offset from each other, so that both bending tabs can be bent around the vertical web, partially or, in certain embodiments, even completely, without hindrance from the other bending tab.

[0031] A further advantage is that the retaining element has a leg section with two bending tabs separated by a material-free area. This allows for a double clamping effect on one side of the vertical web, thanks to the bent bending tabs. Alternatively, more than two bending tabs can be present, for example, two or more on one leg section and / or one bending tab, or two bending tabs, on the other leg section.

[0032] Advantageously, the retaining element is located in a front end section of the fixed rail. This allows for easy installation and bending of at least one bending tab on a front vertical web of the rod assembly, which is easily accessible from the front or from the operating side of the furniture or kitchen appliance when the flap is open. Additionally, it is advantageous or even necessary to provide a further attachment point in another or rear section of the fixed rail for connecting the device to another point on the rod assembly.

[0033] Furthermore, it is advantageous that the holding means have two retaining elements located on the fixed rail, which are designed for connecting the device to the rod assembly. The retaining elements are offset along the length of the fixed rail, in particular one retaining element each in a front end section of the fixed rail and in a rear end section of the fixed rail, spaced appropriately so that each retaining element can be brought into contact with a respective vertical web of the rod assembly. The retaining elements can be identical or different and are offset from each other in the longitudinal direction of the fixed rail according to a horizontal distance between two vertical webs of the rod assembly.

[0034] Finally, it is advantageous if the holding device has a locking mechanism for automatically securing the device to the rod assembly. This enables secure attachment of the device to the rod assembly, particularly during the installation process itself, without further measures such as bending a tab.

[0035] Releasing the locking mechanism is only possible by deliberately removing the device from the rod assembly or vertical web. Accordingly, the locking mechanism preferably comprises a spring section or spring element that is attached to the outside of the retaining element, for example, by subsequent welding, on the contact side. A free, resiliently movable end of the spring section is designed, for example, as a spring arm, which is appropriately sized to project slightly into or through the opening in the leg section, preferably approximately 0.5 millimeters from the outside. The spring arm is designed so that when the retaining element is attached or slid onto the vertical web, i.e., when the device with the retaining element is moved relative to the vertical web in the direction of S2, the spring arm abuts the bearing section and is pushed slightly away in the direction of P1.After passing over the spring arm and bearing section, the bent spring arm snaps or springs back into the opening behind the bearing section (e.g., the embossed section), thus securing the holding element or device. To facilitate passing over the spring arm and bearing section, the spring arm is bent at the front, for example, if it is a sheet metal tab, or has a convex shape at the front.

[0036] The invention also extends to a piece of furniture or a kitchen appliance with a device according to one of the advantageous embodiments described above. This provides an advantageous piece of furniture or kitchen appliance.

[0037] A sliding element is advantageously mounted horizontally slidably on the respective inner side wall of the furniture or kitchen appliance, which is provided with a respective rod arrangement, by means of two laterally acting devices. Character description

[0038] Further features and advantages of the invention are explained in more detail with reference to a schematically illustrated embodiment.

[0040] For corresponding elements of different embodiments, the same reference symbols are sometimes used below.

[0041] The Figures 1 to 5relate to a device 1 not according to the invention for guiding a sliding element (not shown) on sections of a rod arrangement 2, which serve as side grids, for example, in an oven 27 or a baking muffle of a cooking appliance such as an oven 26 (see. Fig. 6 The device 1 for guiding the oven is designed as an oven extension 3, which is shown here as a partial extension and comprises a fixed rail 4 and an extension rail 5, each made of sheet metal. The extension rail 5 is telescopically displaceable relative to the fixed rail 4 via a bearing arrangement not shown, such as a heat-resistant roller bearing. The device 1, or rather the oven extension 3, which is shown in the fully retracted state of the extension rail 5 and the fixed rail 4, is shown in the Figs. 1-3 Only a front end section is shown.

[0042] In the operating state of the oven extension 3, a sliding element (not shown), such as a cooking rack or a baking tray, rests on two devices 1 attached to side racks in the oven 27 and can be slid out of the oven 27 in a horizontal extension direction P1 and into the oven 27 in the opposite insertion direction P2. The two side racks are each detachably suspended from a side wall or inner walls 28, 29 of opposite side walls of the oven 27.

[0043] To receive the sliding element in the oven 27, a section of each of the opposite edges of the sliding element, i.e., a right-hand edge and a left-hand edge of the sliding element, is supported against the respective device. The lower, double-sided support of the sliding element is provided by an upper horizontal web 6 of the extension rail 5, which extends over the entire length of the device 1.

[0044] The rod arrangement 2 typically comprises several vertically offset horizontal bars 8 and several horizontally offset vertical bars 7, wherein the horizontal bars 8 and the vertical bars 7 are connected to each other at their points of contact and are spatially perpendicular to each other, together forming the rod arrangement 2 or the side grid. The rod arrangement 2 is described in the Figures 1 to 3 a section of a vertical bridge 7 is shown and in Fig. 3Additionally, a section of a horizontal web 8 is connected to the vertical web 7 and at least one further vertical web of the rod arrangement 2. In the Fig. 4-6 The entire rod arrangement 2 is visible.

[0045] To prevent or limit any possible relative movement of the edge section of the push element placed on the web 6 of the device 1, mechanical stops 9 and 10 are provided at the front end region of the device 1. The end stop 9 is formed by a vertically oriented sheet metal strip with an inwardly bent head section 11, and the stop 10, located further back on the web 6, is formed by a nose-shaped upward bend in the web material.

[0046] A retaining element 12 is provided on the fixed rail 4, which is shown here as a separate element made of sheet metal and is attached to an inner longitudinal side 13 of the fixed rail 4, for example with a clinch connection.

[0047] The retaining element 12 has a gripping section 23 that is open on one side, or on a side open in the extension direction P1 of the guide, or on an open front side. The gripping section 23 comprises a contact side 14 and two bending tabs 15 and 16. The contact side 14 provides a stop for the vertical web 7 in the insertion direction P2. The open side is limited by a stop 19 at a distance that is slightly larger than an outer dimension of the vertical web 7. The stop 19 is preferably a flat surface or a sheet metal section that is present opposite the contact side 14.

[0048] The two bending tabs 15, 16, separated by a gap-like or material-free area 24, belong to a leg section 17 of the gripping section 23. Opposite leg section 17, there is another leg section 18 of the gripping section 23. The two leg sections 17 and 18 are connected to each other via the contact side 14, with the two leg sections 17 and 18 projecting at an angle, preferably at right angles, on the same side of the contact side 14. The U-shaped section of the holding element 12 formed by the contact side 14 and the two leg sections 17 and 18 provides a receiving area 20 for the vertical web 7. The distance between the two leg sections 17 and 18, according to the corresponding extent or width of the contact side 14, is appropriately matched to an outer dimension of the vertical web 7 or its diameter.

[0049] The device 1 can thus be attached to the rod assembly 2 by threading the retaining element 12 onto the vertical web 7, optionally with a further retaining element further back on the fixed rail 4 on another rear vertical web (not shown) that is offset horizontally to the front vertical web 7 and is located further inside the oven on the rod assembly 2. Accordingly, the corresponding additional retaining element is provided further back on the fixed rail 4 for this purpose.

[0050] To attach the device 1 to the rod assembly 2, the device 1 is correctly aligned, i.e., longitudinally in a horizontal orientation with the holding element 12, and brought into contact with the vertical web 7 from the side in a first horizontal direction S1 and then transversely to this in a second horizontal direction S2. In doing so, a longitudinal section of the vertical web 7 comes into contact with the receiving area 20 on the inside of the contact side 14 and on the inside of the two leg sections 17 and 18 (see figure). Fig. 1 ). In addition, a bearing section 21, which projects outwards on the vertical web 7 towards the interior of the oven or towards the inner longitudinal side 13 of the fixed rail 4, engages precisely in contact with a locking section 22 designed as a recess or opening 25 in the leg section.

[0051] With the engagement of the bearing section 21 with the locking section 22 on the retaining element 12, displacement of the device in the vertical direction or in the longitudinal direction of the vertical web 7 is prevented. To also secure the device 1 against removal forwards or forwards in a horizontal direction, in a subsequent assembly step the bending tab 15 is bent with its free end towards the vertical web 7, so that the entire bending tab 15 wraps around the vertical web 7 in contact with it (see figure). Fig. 2 , 3 ). In this process, compressive forces act to fix the device to the vertical web 7. Accordingly, the device 1 can be fixed further back on the inner longitudinal side 13 to another vertical web of the rod arrangement 2 using a corresponding holding element.

[0052] For even more secure fixation of the device to the vertical web 7, the further or lower bending tab 16 can also be plastically deformed and bent over, just like the upper bending tab 15, so that it fits snugly against the outside of the vertical web 7. This bending can be easily done with a tool such as pliers, for example, combination pliers. In the illustrated embodiment, the lower bending tab 16 is shown not bent over.

[0053] Fig. 4 The figure shows, obliquely from the front, two vertically offset parallel devices 1, which are pushed together and attached to the rod arrangement 2. The view is a full view of an outer side, i.e., a side that, in the operating state of the devices 1 in the oven 26, according to Fig. 6 is aligned to the interior of the oven 27.

[0054] Fig. 5 shows the arrangement according to Fig. 4in a full view of an inside of the rod arrangement 2 or of a side which in the usable state in the oven 26 according to Fig. 6 is aligned with an inner wall 28 of the oven 27.

[0055] Each device 1 is configured as described in the Figs. 1-3 A retaining element 12 is shown in the front area of ​​the fixed rail 4. Additionally, a retaining element 31 is also provided in the rear end area of ​​the fixed rail 4 for gripping a section of a rear vertical web 7, which is designed corresponding to the front vertical web 7.

[0056] Instead of the rear retaining element 31, an identical retaining element to the front retaining element 12 may be provided.

[0057] In Fig. 6The oven 26 is shown with the oven door 30 partially opened, so that the interior with the baking tube 27 is visible and accessible to a user from the front. The baking tube 27 has a rod arrangement 2 attached to the inner wall 28 with a device 1 attached to it. On an inner wall 29 of the baking tube 27 opposite the inner wall 28, which is in Fig. 6As is not apparent, a corresponding rod arrangement 2 with a corresponding device 1 is provided at the same vertical height. A common sliding element, such as a baking tray, can be placed on top of the two devices 1 thus attached, on their supports 6. The baking tray, supported along its longitudinal edges on the two devices 1 and supports 6 respectively, can therefore be pulled out towards P1 and pushed in towards P2 relative to the oven 27. In doing so, the extension rail 5, together with the baking tray, moves relative to the fixed rail 4 and to the rod arrangements 2, which are fixed to the inner walls 28, 29.

[0058] In the Figs. 7-8An alternative holding element 32 without further elements of the device, or shown alone, is attached to a section of a vertical web 7. The holding element 32 differs from the holding element 12 only by an additional bearing section 33 and a locking arrangement 34. The bearing section 33 allows the holding element 32 to be attached to a section of the vertical web 7 from both sides or via two separate sections. Figs. 9 and 10 The rail arrangement (not shown) with fixed and extendable rails of a partial or full extension slide is fixed relatively stably to the fixed rail.

[0059] The locking arrangement 34 serves to ensure that the retaining element 32, and thus the associated device, can be automatically and securely attached to the rod assembly or the vertical web 7. Releasing the locking mechanism is only possible by deliberately removing the device from the rod assembly or the vertical web 7. Accordingly, the locking arrangement 34 comprises a spring section 35 or a spring element that is attached externally to the retaining element, for example, subsequently, for example, welded to the outside of the contact surface 14. A free, resiliently movable end of the spring section 35 is designed as a spring arm 36, which is appropriately adapted to the opening 25 in the leg section 18, for example, formed as a cutout, and projects slightly into or through it, preferably by approximately 0.5 millimeters from the outside. The spring arm 36 is designed so that during attachment or removal,Sliding the retaining element 32 onto the vertical web 7, i.e., when the device with the retaining element 32 is moved relative to the vertical web 7 in the direction of S2, the spring arm 36 abuts the bearing section 21 and is pushed away or deflected slightly in the direction of P1 (see . Fig. 8 After passing over spring arm 36 and bearing section 21, the bent spring arm 36 snaps or springs back into the opening 25 behind the, for example, embossed bearing section 21, thus achieving the secured position of the holding element 32 or the device, which the Figs. 7 and 8 to show. To make it easier to drive over spring arm 36 and bearing section 21, spring arm 36 is bent at the front, for example if it is a sheet metal tab, or has a convex shape at the front.

[0060] The retaining element 32 is thus secured on the vertical web 7 in height or vertically by the bearing section 21 in the opening 25, in width by the engagement of the vertical web 7 itself by the leg sections 17, 18, and in depth or longitudinally along the fixed rail (not shown) or in the direction of P1 by the spring locking mechanism, which can be set with the locking arrangement 34, between the spring arm 36 of the spring section 35 and one side of the bearing section 21. Bending the bending tab 15 is not necessary or can be done optionally or additionally.

[0061] Advantageously, the spring locking mechanism between the spring arm 36 of the spring section 35 and the bearing section 21 can only be engaged by using a tool such as a screwdriver, thus allowing the device 1 to be disassembled from the rod arrangement 2.

[0062] Another variant of a holding element 37 based on the same principle as the locking principle according to the holding element 32, with a locking arrangement 34, is shown by the Figs. 9 and 10 The retaining element 37 differs from the retaining element 32 solely by the arrangement of a spring section 38. Unlike the spring section 35, the spring section 38 is attached to the outside of the stop 19, for example, or preferably, by welding, or as shown in the Fig. 9, 10 indicated by a clamping bend. An elastically movable spring arm 39 of the spring section 38, or a free end of the spring arm 39, extends from the other side towards the opening 25 and, in the fastened state, rests against the bearing section 21 in a locking manner. Similarly, when the retaining element 37 is attached to the vertical web 7, the spring arm 39 is initially pressed elastically outwards as it passes over the bearing section 21 and, after passing over it, snaps back into the opening 25 behind the bearing section 21 to secure it in place.
