Description

Covering for lining of wall

Technical Field

The present application relates to a shading piece for a lining of a wall and a method for fixing a shading piece.

Background

For visual and tactile reasons, it is advantageous to provide the wall with a lining. Thereby giving the user a pleasant impression. Furthermore, contact or wear of certain parts of the wall can be avoided.

However, access to a particular section of the wall may be required even after lining the wall. This may be necessary in cases where, for example, otherwise hidden numbers, such as vehicle identification numbers applied to different parts of the vehicle, must be viewed. For this purpose, it can be provided, for example, that a part of the lining can be lifted from the wall, so that the corresponding wall section can be accessed.

However, it has been found that such sections which can be removed from the wall have a low mechanical stability. In particular, a high mechanical stability is required in the region of the user stepping onto the respective position, so that, for example, the user's foot does not significantly sink into the floor or the lining is not moved. Furthermore, in order to avoid or at least reduce ageing due to climate influences, it must be ensured that the lining can be reattached to the wall after removal.

Disclosure of Invention

The object of the present application is to at least partially overcome the disadvantages previously known from the prior art. The object of the present application is, inter alia, to provide a covering for lining walls and a method for fastening a covering, wherein the mechanical stability of the fastened covering is increased and at the same time the covering gives the user a visually pleasing impression and can be produced and assembled at low cost.

The aforementioned technical problem is solved by a covering element (Blende) for lining of walls and a method for fixing the covering element. Other features and details of the application are set forth in the accompanying description and drawings. The features and details described in connection with the inventive trim part are also obviously applicable here in connection with the inventive method and vice versa, so that individual inventive aspects are always or can be referred to each other in the sense of the disclosure.

According to a first aspect of the application, a trim piece for a lining of a wall, in particular for a lining of a vehicle body provided with a lining (ausgekleidet), is provided. The trim piece has a housing designed to accommodate a foldable section of the lining of the wall. The housing has a support part, which is designed to be supported on the wall.

In connection with the present application, a covering element is understood to mean a covering element which can at least partially cover a predetermined region of another component, in particular a lining of a wall. It can also be provided that the covering covers the entire predetermined area.

In connection with the present application, a liner is understood to be an assembly suitable for modifying the surface properties of a component located therebelow. In this case, this can be, for example, an insulating material, in particular for sound and heat transfer, or a decorative layer (for example, a carpet). Composite liners having multiple components, such as insulation and decorative layers, may also be provided.

The wall may be a mechanically stable member. In particular, this may be referred to as a vehicle floor. However, it can also be provided that the wall is a mechanically stable component on the vehicle, for example a vehicle roof. In particular mechanically stable components on which the vehicle identification number is applied can be regarded as walls according to the application.

In the context of the present application, a housing may refer to a geometry designed to at least partially accommodate another geometry therein. The housing can be designed to be substantially closed or can be provided with an opening.

The foldable section of the cover part is designed such that this foldable section can be lifted from the wall to which the rest of the cover part is connected. Such a foldable section can be produced, for example, by cutting into (or otherwise cutting into) the cover. The cut can in particular be realized such that the cut is not performed in a closed manner (i.e. the start and end of the cut do not coincide in one position), but at least one section remains, which can then be used as a hinge for folding over the cover.

In the context of the present application, a support means a geometric body which is designed as a support for an object connected to the support. In other words, the support serves to mechanically support an object, in particular a housing, connected to the support on another object, in particular a wall, and thereby provides stability with respect to said other object, so that the covering as a whole and the foldable part of the covering move only slightly or not at all, even under mechanical load. It can be provided that the support is designed as part of the housing. The production of the decorative covering is thereby simplified, so that the decorative covering can be produced particularly cost-effectively. However, it can also be provided that the support is designed as at least one additional component or as an additional section of the housing.

In this way, the wall below the covering is generally provided with a particularly high mechanical stability, which is fully utilized by the covering according to the application. This high mechanical stability is used by the support to hold the covering itself and the covering contained in the covering.

In addition, in the covering according to the application, it can be advantageously provided that a covering strip is provided on the housing, which covering strip is designed to cover the edges of the foldable sections. In other words, the covering element may have a closing element which covers the edge of the foldable section of the lining, in particular in the closed or covered state of the covering element. The advantage achieved thereby is that in the closed state of the covering, the edges in the lining for producing the foldable sections cannot be seen by the user. Furthermore, the covering piece can be opened more easily when the user grasps behind the covering slat. It may also be provided that the covering strip covers other parts of the lining. The mechanical stability of the covering strip itself can thereby increase the stability of the covering as a whole, and a pleasant visual impression can be produced.

In the context of the application, it is also conceivable for the support to be formed around the housing and/or for the support to be formed as at least two strips, at least two of the strips being arranged opposite one another on the housing.

In other words, it can be provided that the support is formed on each side of the housing, as a result of which a particularly high stability can be achieved. In this case, it can be provided that the support has a die-cut at least in sections in order to reduce the mass of the support. This provides the advantage that the costs in manufacturing can be reduced.

A slat is understood to be a substantially narrow, long component. Since at least two strips are arranged opposite one another, a high stability is ensured even at low mass and thus a lower cost of the support (compared to a completely encircling support) is also ensured.

It can also be provided that the contour of the support against the wall is adapted to the corresponding wall contour. For example, if the wall is not completely flat in the region of the foldable section of the lining, the support is adapted accordingly to this special shape. A particularly high mechanical stability is thereby likewise achieved.

However, it is likewise possible to provide that the support is planar. The advantage achieved thereby is that a particularly high mechanical stability is achieved for flat walls and at the same time no special form-fitting (of the walls) is required for the production of the trim part or the support part, so that more versatile parts can be produced, thereby reducing costs. This is usually also achieved in that there is usually a flat section of the wall.

In the covering according to the application, it can be provided that a locking projection is provided on at least one side of the housing, which locking projection is designed for locking with the lining. In other words, it can be provided that a undercut (Hinterschnitt) is provided on one side of the housing, which undercut is suitable for engagement into the lining when the covering is supported on the wall. It can be provided that the latching projections are adapted to the lining in such a way that they engage between the different layers of the lining. The advantage achieved thereby is that a particularly good locking can be achieved. The latch can engage, for example, between the decorative layer and the insulating layer.

It is also conceivable within the scope of the application for the housing to have a support surface which is designed to support at least a part of the foldable section in a planar manner on the support surface when the foldable section is accommodated in the housing. In other words, it may be provided that the foldable section of the lining rests against the section of the covering element when the foldable section is accommodated in the housing. The mechanical stability of the covering element is further increased by the bearing surface. The bearing surface may be closed or have at least one opening. A particularly good mechanical stability is achieved by the closed bearing surface. The provision of at least one opening offers the advantage that weight and manufacturing costs can be saved. It can also be provided that the support surface is connected to the housing on at least three sides of the housing, and that the surface between the connections extends in particular between the housing and the support surface.

In addition, in the covering according to the application, it can be advantageously provided that the support surface is provided for receiving at least the decorative layer of the lining or the damping layer of the lining. In other words, the support surface can be designed such that it receives the entire liner or only one or more layers of the liner. For example, it can be provided that the support surface only receives the decorative layer. This ensures on the one hand the mechanical stability of the decorative layer and on the other hand, for example, the insulation layer arranged below the decorative layer can be protected from being compressed by the user, so that the insulation properties remain unchanged.

Furthermore, in the covering according to the application, it can be advantageously provided that the covering strip and the housing are connected by a hinge, which is arranged in particular on the insertion side of the housing. In other words, the cover strip can be designed to be foldable. The advantage achieved thereby is that the covering strip can be turned over from the rest of the covering piece and thus, for example, the edges of the foldable sections of the lining can be accessed.

The hinge can be designed as a film hinge. The film hinge is particularly inexpensive to manufacture, thereby enabling the cost of the covering trim to be reduced. It can also be provided that the hinge is designed as two mutually opposite pins which engage in corresponding recesses (Ausnehmung) on the housing. The hinge thus formed is particularly durable and allows particularly easy movements, since no mechanical stresses are exerted on the moving components.

It can furthermore be provided that the cover strip and the support surface are connected to one another and that the cover strip and the support surface are jointly connected to the housing, in particular to the strip, by means of a hinge. This achieves the advantage that, when the cover strip, which is particularly easy to access by the user, is lifted, the lining lying against the support surface is simultaneously lifted, so that the wall is more easily accessible.

Furthermore, in the covering according to the application, it can be advantageously provided that the housing has a width and a length of between 40mm and 350mm, preferably between 100mm and 200mm, respectively, in the plane of the lining. In other words, the trim piece can be used particularly advantageously when the trim piece has a defined size. In particular, in the order of magnitude corresponding to the tread surface of the user's shoe, there is a need to ensure mechanical stability sufficient to prevent the user from getting trapped. For significantly smaller faces, the mechanical stability requirements are generally not increased. However, for a much larger face, further stabilization may be necessary.

It is also conceivable within the scope of the application for at least the housing and the support to be formed in one piece, in particular as an injection molded part. In other words, it can be provided that at least all parts of the housing and the support, in particular the covering, are composed of a continuous body, so that no connecting elements are required for connecting the individual components. The advantage that can be achieved thereby is that the covering element can be produced particularly simply and cost-effectively.

Provision may be made for the material of the trim part to be designed in a uniform manner. The advantage achieved thereby is that the covering element can be produced particularly cost-effectively. It is likewise possible to provide that the decorative part is produced from a plurality of components, in particular in a multicomponent injection molding process. The advantage achieved thereby is that the respective optimum material can be used in accordance with the respective requirements, for example in terms of appearance and mechanical stability.

It can also be provided that the decorative part has polypropylene (PP) or high crystalline polypropylene (HCPP). The advantage of using polypropylene is that polypropylene is particularly inexpensive and thus enables particularly inexpensive production of the decorative covering. The high crystalline polypropylene also provides the advantage of being less prone to scratching. The plastics used may furthermore be fibre-reinforced or, for example, talc-reinforced, in order to further increase the mechanical stability of the covering.

According to a further aspect of the application, a method for fixing a trim part, in particular a trim part according to the application, is provided. The method according to the application comprises the following steps:

a foldable section of the liner of the wall is turned open,

inserting the shell of the trim piece over the lining of the wall, so that the foldable section of the lining of the wall is accommodated in the shell,

co-closing the lining of the wall with the covering,

wherein in the closed state the support of the covering element rests against the wall.

It is important for the method that the support of the covering element is in contact with the wall in the closed state, so that the covering element can be supported on the wall, thereby increasing the mechanical stability of the covering element. The individual steps can be carried out by the assembler or can also be carried out automatically, in particular fully automatically.

The method according to the application therefore brings about the same advantages as have already been described in detail with reference to the shading piece according to the application.

In the method according to the application, it is also conceivable for the latching projections of the housing to latch with the foldable sections. In other words, it can be provided that in the closed state of the foldable section, the lining latches with a side recess on the housing of the covering part. The advantage achieved thereby is that a particularly stable connection is achieved between the trim part, the lining and the wall.

Detailed Description

Fig. 1 shows a trim piece 100 for a lining 200 of a wall 300. With reference to fig. 1, the geometric features of the trim piece 100 are first described. The common function between the trim piece 100 and the liner 200 and the wall 300 is described in more detail in connection with fig. 2 and 3 below. For clarity, liner 200 is not shown in fig. 1. Wall 300 may also be a lined body 310 such as shown in fig. 5. As shown in fig. 1, the wall may also have a vehicle identification number 320 that may be made visible to a user by flipping the trim piece 100 over.

As shown in fig. 1, the trim piece 100 may have at least one shell 110 designed to accommodate the collapsible section 210 of the liner 200 of the wall 300. It is also shown that the housing 110 has a support 120 which is designed to be supported on the wall 300. The advantage achieved by supporting the housing 110 on the wall 300 by means of the support 120 is that the shading piece 100 has an increased mechanical stability compared to a shading piece or a corresponding support on the wall 300.

The embodiment of the trim piece 100 shown in fig. 1 has a cover strip 130 on the housing 110, which is designed to cover the edge 220 of the foldable section 210. The illustrated cover strip 130 extends around a trim opening 113 that enables a portion of the foldable section 210 to be seen in the installed state of the trim 100. Fig. 2, for example, shows an edge 220 of the foldable section 210. By providing a cover strip 130, the edge 220 can be completely covered, as is shown for example in fig. 5.

It can furthermore be provided that the support 120 is designed circumferentially around the housing 110. In fig. 1, the support 120 is designed partially around the housing 110, however with an opening at the insertion side 112. It is also conceivable, but not shown here, for the support 120 to also have an opening on the insertion side 112, but still serve as a front support to connect the left support to the right support. The liner 200 must be guided above or below the support portion of the front side when the liner 200 is inserted. Although the connection of the trim piece 100 to the lining 200 is thereby made somewhat more complex, the stability of the trim piece 100 may be further improved.

It can also be provided that the support 120 is formed as at least two strips 121, wherein at least two of the strips 121 are arranged opposite one another on the housing 110. In the exemplary embodiment shown in fig. 1, at least the left-hand strip 121 and the right-hand strip 121 are arranged opposite one another, wherein the left-hand strip and the right-hand strip are connected to one another by the rear-hand strip 121.

Fig. 1 also shows that a latching projection 140 is provided on at least one side of the housing 110, which is designed to latch with the lining 200. The latching projections 140 shown in fig. 1 are arranged here at a height in which they do not latch with the entire lining 200, but only with parts of the lining 200, in particular with the decorative layer 230.

It may be provided that the housing 110 has a support surface 150, which is designed to support at least a portion of the foldable section 210 in a planar manner on the support surface 150 when the foldable section 210 is accommodated in the housing 110. As can be seen from fig. 1, the support surface 150 can be arranged in different positions, so that it can selectively receive the entire liner 200 or only parts of the liner 200 when the foldable section 210 is accommodated in the housing 110. Accordingly, the bearing surface 150 may be configured to receive at least either the decorative layer 230 of the liner 200 or the shock absorbing layer 240 of the liner 200. In the embodiment shown in fig. 1, when the trim piece 100 is in the closed state, an upper portion of the liner 200 is received, for example, on the bearing surface 150 and a lower portion of the liner 200 is located below the bearing surface 150. Fig. 1 also shows that the bearing surface 150 may have at least one recess 151. Thereby enabling the weight of the trim piece 100 to be reduced, saving material costs, and also enabling the vehicle identification number 320 to be more easily seen.

The support surface 150 can be designed in particular for breaking the kinematic chain of the support 120 or of the strip 121. The advantage achieved thereby is an increased torsional stiffness of the trim piece 100.

As shown in fig. 1, the cover strip 130 and the housing 110 can be connected by a hinge 111, wherein the hinge 111 can be arranged on the insertion side 112 of the housing 110. This allows the cover strip 130 to be folded over even after the installation of the covering element 100 and thus, for example, the edge 220 to be accessible without removing the covering element 100 from the wall 300. In this case, it is particularly advantageous if the hinge 111 is embodied as a film hinge, since it can be produced particularly cost-effectively.

It may be provided that the housing 110 has a width and a length in the plane of the lining 200 of between 40mm and 350mm, preferably between 100mm and 200mm, respectively. Here, the case 110 does not necessarily have a substantially square or rectangular shape as shown in fig. 1. Other shapes, such as oval, are also contemplated. Advantageously, the shape of the shell 110 is designed such that it remains unchanged over the length of the insertion of the foldable section 210 or narrows starting from the insertion side 112, so that the shell 110 can be pushed over the liner 200 more easily.

Furthermore, at least the housing 110 and the support 120 may be of one-piece design. The one-piece component can be embodied here as an injection molded part. This enables the trim part 100 to be produced particularly cost-effectively.

Finally, in fig. 2, a collapsible section 210 of the liner 200 is shown. Such a collapsible section 210 may be manufactured, for example, by cutting into the liner 200. If the cut is not closed, i.e. the start of the cut and the end of the cut do not touch, then an uncut section remains, which can be considered as a connecting line between the start of the cut and the end of the cut and act as a hinge for the foldable section 210.

It may be advantageously provided that the shape of the foldable section 210 corresponds to the geometry of the housing 110, so that the housing 110 can be inserted onto the foldable section 210 more easily.

A method for fixing a trim piece 100 according to the present application can be described with reference to fig. 3. The method according to the application has the following steps.

First, the collapsible section 210 of the liner 200 of the wall 300 is flipped open. The foldable section 210 is then in the unfolded state I. In this unfolded state, for example, the (vehicle identification) number applied to the wall 300 can be seen. However, if no trim piece 100 is provided, on the one hand it is difficult for a user to open the foldable section 210 and the mechanical stability of the liner 200 is reduced due to the cut-out.

In a next step, the shell 110 of the trim piece 100 is inserted over the lining 200 of the wall 300, so that the foldable section 210 of the lining 200 of the wall 300 is accommodated in the shell 110. In other words, the trim piece 100 and the foldable section 210 are in the nested state II. This state also corresponds to a state in which, for example, a user who wants to read a number applied to the wall 300 lifts the foldable section 210 by means of the covering piece 100.

Finally, in a further step, the lining 200 of the wall 300 is jointly closed with the trim part 100, wherein in the closed state III the support 120 of the trim part 100 rests against the wall 300. The mechanical stability of the trim piece 100 is increased by the abutment of the support 120 on the wall 300. In the closed state III, the user can, for example, step on the foldable section or mechanically load the foldable section 210 without sinking in.

It can be provided that, in particular, when the covering part 100 is in the closed state III, the latching projection 140 of the housing 110 latches with the foldable section 210. Thereby further improving the mechanical stability of the trim piece 100 and the lining 200.

Fig. 4 shows another embodiment of a trim piece 100 with a hinge 111. As can be seen in fig. 4, the hinge 111 is designed as two mutually opposite pins which engage in corresponding recesses on the strip 121. It can also be seen that the cover strip 130 is connected to the support surface 150 by a circumferential edge section, on which the pin is formed. This achieves the advantage that, when the cover strip 130, which is particularly easy to access by the user, is lifted, the lining 200 lying against the support surface 150 is simultaneously lifted, so that the wall 300 is more easily accessible. As can also be seen from fig. 4, the contour of the support 120 or of the strip 121 lying against the wall 300 is adapted to the contour of the wall by means of corresponding recesses.

The above description of embodiments describes the application only in the context of examples. Of course, individual features of the embodiments can be combined with one another freely if technically significant, without departing from the scope of the application.
