Description

Seating in two-shell construction

for receiving decorative sheets

The invention relates to a chair formed from two interconnected seat shells, which as a connected component seat and back of the chair bil ^¬ the according to the preamble of claim 1.

It is already disclosed in the prior art to make seating so that they can serve to receive from ^¬ interchangeable decorative panels or advertising themes. The main focus of previous Veröffentli ^¬ tions is the use of the back of chairs and seats for accommodating the decorative panels or advertising displays.

The German utility model DE 9412911 ^¬ fenbart of a piece of furniture in the form of a chair in which the backrest 2 from transparent plastic sheets is formed between which a printed sheet is removably inserted. These 2 plastic plates are used here in 2 ^{seit ¬} union guide. There are therefore moving plates to guide the bow. In addition, the ^¬ Of fenbarung is a part of the chair, that limits the backrest.

The published patent application DE 202004002419 U1 shows a three-dimensional seating furniture made of a flexible ^sheet material, wherein the attachment of advertising or company logos is to take place directly on the flexible material.

The published patent application DE 4428961 AI discloses ei ^¬ ne seat backrest with interchangeable decorative plate.

Here, it is provided to make the backrest like a kind of plug ^¬ frame, with an upper-side slot remains, in which a picture motif can be inserted. It is a gap space between two plates is provided and an upper-side opening into which the picture element or dss forming film element can be inserted. The result is a backrest that can be shaped like a picture frame by varying decor panels.

The patent application DE 19849644 AI in turn also shows a seat which Who can be designed ^¬ beträgers individually by inserting a. This is seen advantage that the seating furniture has a transparent plate on ^¬ under which the advertising medium can be attached. This plate is usually designed as a seat. This through ^¬ view plate is designed as a removable or wegklappbare or pivotable advertising space, which must be opened to insert the advertising medium and then closed again. The advertising will be inserted ^¬ and closed the one-piece or two-piece flap back into the seat pan. This results in the basic structure of a seat. It is therefore a complex construction with mechanically articulated moving parts.

Finally, from the utility model DE 20 2006 002 239 Ul an advertising medium is known, in which case an advertising element in the form of a backrest between 2 block-like elements is clamped. Here too, ^only part of the advertising support which can also be used as seating furniture can be used as advertising space, namely the backrest.

It is apparent from the prior art no solu- tion, which he ^¬ enables no moving parts or mechanical components, which simultaneously satisfies a usual standard in terms of comfort, ease of handling, stacking and others. A full-area design of a seat Against this background, it is the object of the prior ^¬ invention invention a seating formed of two miteinan- the connected seat shells, which form a seat and backrest of the seat as a connected component, so to ge ^¬ stalten that almost the entire surface of the chair can be easily provided with a decal sheet. In this case, an easy replacement of the decal sheet should be possible and at the same time be arranged in the seating so that it undergoes no wear during use.

This is achieved according to the invention by a chair with the characterizing features of claim 1.

The subclaims have advantageous from ^¬ designs of the chair to the subject. It follows, on the one hand, that the inventive solution of a composite of two approximately identically ^¬ th seat shells basic body of the chair no moving elements present, which must be solved or moved to the arrangement of a decal sheet. Rather, the seating itself is designed by the construction of 2 shells so that between these shells the flat gap remains, in which now almost the entire base of the chair can be introduced comprising a decorative sheet.

In this way it can be achieved that the seating itself can be changed in its appearance by the introduction of the Dekorbogens completely in the impression, which may be useful both for use in the private sector in coordination, for example, to other furniture, floor or wall coverings. On the other hand, however, especially in the field of commercial use of seating furniture, for example in trade fair construction, can have great advantages, since so seating can be individually adapted to the occasion. Here, in particular, the furniture is designed for specific occasions such as product presentations or corporate events by adapting certain designs such as company logos and corporate identity.

In this context, it is particularly important that the chairs meet the known requirements for stackability, durability and comfort. The present solution here has so far not deficits since the seat is a com ^¬ pletely integrated in the seat and backrest together amount ^¬ sat seat that standards fully meets the requirements of usual standard.

A central inventive idea here is that between the two seats the full-surface gap is formed into the now through a slot-shaped access opening a decal sheet can be introduced, which thus characterizes the shape of the chair by at least one transparent upper seat. The arrangement of the access opening can be done on the one hand on the upper side of the backrest on the Ge ^¬ velvet width or also on a slot-like access opening in the lower seat, so back on the surface of the seat over the width of which are arranged ^¬ order.

In particular, the transition region from backrest to seat surface from the vertical to the horizontal appears to be suitable for arranging the access opening, whereby it is also possible here to insert the decal sheet consisting of several segments into the planar gap space between the seat shells.

In addition, the introduction of the decal sheet in the planar gap space between the seat shells can be facilitated by further openings in the lower, rear shell, which are arranged extending approximately transversely to the access opening. These openings thus run in

Longitudinal extension of the main body of the chair and make it possible to chen a manual introduction of the decal sheet by pushing the decal sheet in the flat gap.

The connection of the two approximately identically shaped seat shells is carried out exclusively in the peripheral edge region either completely circumferential or punctiform. Here, on the one hand, bonding in the edge area is possible, wherein the shape of the seat shells must have corresponding spacer means in order to produce the planar gap space between the seat shells. These spacers can be made either by a circumferential survey on at least one of the seat shells in the edge region and aligned to the second seat. However, these spacers can also be arranged only occasionally circumferentially in the edge region of the seat shells or strei ^¬ fenförmig or selectively placed as a separate spacer body between the seats when their connection.

In this way, it is achieved that the areal gap between the seat shells approximately the complete

Seating comprises seating, whereby the full-surface design is made possible by the decal sheet.

In principle, in addition to bonding or welding, there is also the possibility of mechanical connecting means, for example screwing together the seat shells to be joined. Here is a particularly advantageous embodiment to achieve by two opposite lateral edges of the seats connecting strips. These strips can advantageously consist of different ^¬ friendly materials, for example, from an already following the shape of the course of the lateral edges of the seat shell metal profile, or but also made of plastic, which either preformed already follows the course of the lateral edges of the seat shells or is designed so elastic that it can be adapted to this shape. The use of side moldings for connecting the shells here has several positive aspects. This concerns, on the one hand, the desired distance between the seat shells, which is necessary for introducing the decorative sheets between the seat shells. Here it is possible to integrate the spacer circumferentially in the profile strip, so that here in cross-section an E-shaped profile strip is formed, where ^{¬ is formed} at the central region of the profile strip as a spacer.

Another design may be configured such that the peripheral connecting strip is designed in the form of a C-profile, in which a spacer can be used, either as loosely inserted or glued approximately T-shaped profile body, for example, made of an elastic Plastic can be formed.

Basically, the configuration of the seat shells joined at their lateral edge profile is possible in a large variety, wherein the central portion should be formed as a spacer means and connecting the outer surface preparation ^¬ the seat shells to each other. Here are different forms of attachment of these strips on the seats conceivable. Advantageously, a screw connection takes place on the seat shells, since this makes it easy to assemble and disassemble the profile strips on the seat shells. But it is also in principle of a plug connection conceivable wherein federar- to the peripheral profile strips term projections are provided which engage in groove-like Vertiefun ^¬ gen at the peripheral edges of the seat shell.

In this connection, in an advantageous embodiment of the invention is provided for the smooth connection between the seat shell and the lateral connecting strip ei ^¬ ne flat depression at the lateral edges of the Sitzscha- len so that they absorb the strength of Verbindungspro ^¬ fils complete. As a result, there is no noticeable transition between the seat surface and the lateral connection profiles arranged therein. The connecting strips are thus completely flat on the

Seat shells on and are sunk in the side recesses.

A positive effect in this regard of this form of connection in relation to an alternative of the permanent bonding of the seat shells to one another is that the connection of the parallel guided identically shaped seat shells is formed as a detachable connection by means of the lateral connecting strips. This, in turn, means that the seating furniture can undergo a variety of both conversions and maintenance.

For example, the seat ^panes can be lifted and cleaned again by ^detaching the lateral connection strips. Alternatively, a seat shell damaged by the wear on the top side could be replaced by a new seat shell, the rest of the seat ^¬ furniture is not affected. Another option would be, for example, to make a Umge ^¬ staltung the chair by changing the side connecting strips. This is for instance possible if you want to switch from a simple design of the chair with a surrounding plastic strip to a wertigere design with a brushed aluminum bar to make the piece of furniture, for example, to a late ^¬ ren time new and upgrade. It is also possible to change certain color designs, which can be achieved by selecting the side connection bar. It is also provided in an advantageous embodiment of the seating furniture according to the invention, also to attach the connecting means to the legs of the chairs on the side moldings or connecting strips and thus to be able to form the bottom surface or the lower seat free of connecting means. This has the advantage that, for example, metallic formed seitli ^¬ che connecting strips are also suitable in better extent to accommodate the introduced through the use of the chair into the material forces than is possible in a plastic material in the lower shell of the chair.

Here is also a variety of design options for the arrangement of the legs or the base of the chair possible. For example, selective screwing can be done on the side mounting strips, which may be formed either independently of the attachment of the bar to the seat shells or combined with this.

In principle, both solutions are conceivable for the embodiment in which the lower shell is colored out ^¬ staltet and transparent only the upper seat and thus the decor sheet is formed recognizable. Alternatively, however, the upper and the lower seat shell can be made of a transparent plastic. In the case of differently shaped upper and lower seat shell, the lower shell may not be transparent seat grundsätz ^¬ Lich also consist of a material other than the listed sat transparent seat shell which has to be manufactured as a rule of a transparent plastic.

There are basically different support frames under the main body of the chair conceivable. For example, it is obvious that a skid frame can be used as well as a classic four-legged stand model, but also others possible solutions are conceivable. A further development of the seating aims to push through this together and speaking mechanically connect to a bank together to ^¬ menführen.

A correspondingly modified higher-frame support frame and an adjustment of the seat shells also makes it possible to design the seat as an elevated bar stool by shortening the backrest> the like.

In the illustrated in Figure 1 design of the chair 1 according to the invention is a typical design of a stackable chair with a base 13 as skid frame, on which the seat is secured, for example by screws. Such seating is widely used in public spaces such as schools or venues. This is a representation, in which the seat according to the invention is composed from the two already BAULI ^¬ chen elements of the upper seat 2 and the lower seat shell. 3 It is due to the transparent upper seat 2 and in the lower

Seat shell 3 arranged perforations 8 can be seen, which serve the insertion of a decorative plate 7, not shown here supportive. In Figure 2, the decorative plate 7 is now formed in this example case of 2 segments 7 'and 7''. This is a design of the inventive solution, in which arranged both at the front edge 11 of the seat surface of the chair as well as on the upper edge 10 of the backrest an access opening 6 in the gap 5 between the upper seat shell 2 and the lower seat shell 3 are. Here, the segments 7 'and 7''of the decorative plate 7 are attached, where represent ^¬ in arrows the insertion direction.

FIG. 3 now shows, on the one hand, the seating 1 according to the invention with the decor panel 7 inserted, as a result of which a full-surface representation of, for example, a graphic representation or a company logo can be arranged engaging the entire seating surface of the chair. On the other hand, an enlarged detail is reproduced here, which reveals the transition of the edge region as the connecting region of the upper seat shell 2 below the lower seat shell 3 with the bond 9 arranged therebetween, as well as the adjoining the adhesion 9 gap space 5 between the seat shells 2 and 3 ,

The exploded view of Figure 4 in turn illustrates from which structural elements the seating 1 is composed. It is here the substructure 13 as

Skid frame shown as a supporting element as well as Ver ^{¬ connecting means} 14, which serve the attachment of the seat on the base 13. Here, it is interpreting ^¬ Lich in this figure 4 in that the transparent seat shell in an upper ge ^¬ closed trained seat shell 2 and including identical shaped lower seat shell 3 is composed, wherein the lower seat shell 3 has additional perforations 8 which in the Introduction of the decorative plate 7 are helpful. In this case, required for this purpose may be to ^¬ arranged hole 6 on the upper edge 10 of the backrest as well as at the front edge 11 of the seat surface, or on both edges. Finally, Figure 5 again shows an exploded ^¬ drawing, in which case the placement of a one-piece decorative plate 7 between the two seats 2 and 3 is apparent. It can be seen that the decorative panel 7 covers approximately the entire surface of the seat shell and thus the entire seat and back surface of the seat can be designed deco ^¬ ratively. Figures 6 and 7 in turn refer to an alternative design in which the seat shells 2 and 3 are not glued but are connected by means of releasably attached to the lateral edge regions 4 connecting strips 15. In principle, these connecting strips 15 may be formed as profiles of different cross-section, but in the illustrated design can be seen in Figure 8 and 9, however, that here an E-profile 17 is used.

The E-profile 17 in this case consists of the side resting on the seat shells 2 and 3 and these connecting arms as from the between the seat shells 2 and 3 extending middle arm, which is the spacer means to the seat ^¬ shells 2 and 3 at the desired distance to hold each other. This middle arm may consist of deviating material from the rest of the profile material, for example, in an aluminum profile made of an elastic plastic.

It is also shown a support bar 16 at the upper end of the backrest, which is attached to the lateral connecting strips 15, screwed in the example shown. This serves to facilitate the handling of the seating 1.

Also on the horizontally extending lower leg of the connecting strips 15 more strips 18 are arranged, which form the connection to the substructure 13. this has the advantage that these areas in which the seating furniture burdening weight forces are particularly effective, not in the plastic of the seat 3, but in the example metallic connection strips 15 are laid, which on the one hand improves the durability of the chair 1, and to ^¬ their the assembly, disassembly and replacement of these Gebü ^¬ le favors.

In the figures 8 and 9, the arrangement of the lateral connection bar 15 is illustrated in section. It han ^¬ delt is an E-profile 17, the middle arm of the Pro ^¬ fils 17 between the seats 2 and 3 generates the necessary gap. 5 In addition, it can be seen that a Ausspa ^¬ tion 19 at the peripheral lateral edges of the seat shells 2 and 3 extends such that the upper and lower arm of the E-profile 17 engages in this and so a smooth transition to the surface of the seat shells 2 and 3 arises ,

Figure 9 also illustrates a possible Fixed To ^¬ supply a substructure 13 of the seat 1 to the seat shells 2 and 3, 15 by means of the side connecting strips In this design, this is achieved by a material cutout in the lower seat 3, into which an angled end of a Be ^¬ fixing strip 19 engages the base 13 and is bolted to the lateral connection bar 15. This buildin ^¬ actuating bar is in turn connected to the base assembly 13 Example ^¬ a skid frame, screwed.
