Description

The invention relates to a passenger dining table a table top, which by means of a folding mechanism on the Back of a passenger seat is set foldable an upper plate, a lower plate and a peripheral edge has, which are formed from flat plastic material and enclose a volume, and the at least one hidden in the volume running between the top plate and bottom plate Has longitudinal guide into which a carrier of the folding mechanism can be introduced.  

Such passenger dining tables are generally known. The waiter plate and the lower plate of such table tops exist ge usually from a very thin (<1 mm) drawn layer of bottom lycarbonate (PC). The top plate and the bottom plate are each because with a raised edge. These edges are matched to each other so that the top plate and the bottom plate can be pushed together, the edges together form a peripheral edge of the table top. In this way volume formed is in the known passenger dining tables A hard foam insert is present, which completes the volume fills out. This hard foam insert provides the necessary Stability of the table top. Because the top plate and the bottom As mentioned at the beginning, plates are made of comparatively thin Made of plastic material that taken ver is equally unstable.

In places where the table top is regularly higher loads, especially pressure loads, are exposed Corresponding pieces of metal are inserted in the hard foam insert foams. This applies e.g. B. for the area over which the flight guest dining tables pushed a bar in the folded state which is an unintentional folding down of the table top avoids. In the rigid foam insert are also common two accessible from a trailing edge, run concealed de Longitudinal guides for holding beams of the folding mechanism foamed. At the rear edge of the table top are corresponding Appropriate openings provided.

The individual components of this table top are for taken each comparatively inexpensive.  

However, there are comparatively many individual parts for the Mon to provide days. This makes the assembly complex. The The top plate and the bottom plate can be in one Tool. The hard foam insert must, however a separate machine.

In addition, the weight of such table tops due to the Use of materials with a comparatively low specific weight is low, but by no means too is neglect.

Against this background, this is the basis of the invention problem in creating a passenger dining table that in a few operations is inexpensive to manufacture and a ge has low weight.

This problem arises with the above-mentioned passenger dining table solved that in the volume a variety of individual chambers is provided, the partitions between the top plate and base plate approximately parallel to the peripheral edge of the Table top run.

The problem underlying the invention is in this Wei se completely solved.

Because due to the fact that the individual chambers of one other dividing walls between top plate and bottom plate approximately parallel to the circumferential edge of the table top fen, pressure loads on the table top from the dividers walls included. A hard foam insert is therefore not uncommon conditionally necessary. The partitions can be done in one operation  be produced with the top plate and / or the bottom plate. In this respect, the assembly is simplified, since ideally only that The top plate and the bottom plate are to be connected to each other. Since the top plate and bottom plate are usually made of the same mate exist and can be manufactured in the same machine NEN, is also an automatic connection of the top plate and Bottom plate conceivable.

The top plate and the bottom plate are preferably in Injection molding process made. Here, the partitions in one injection molding process together with the top plate and / or the lower plate can be produced.

The plastics approved in aircraft construction can be found in the Manufacture or process injection molding process.

In summary, it is possible to use the passenger Dining table with minimal installation effort, ideally without anyone Assembly effort to manufacture, since a common manufacturer top plate and bottom plate in an injection molding machine it is possible to use these plates during or immediately afterwards to the necessary injection molding processes with each other connect, also z. B. if the plates are not yet are cured.

Because of the partitions, the flight according to the invention has guest dining tables provide the necessary stability. Since no rigid foam Insert in the volume of the table top is provided, can the passenger dining tables according to the invention even lighter than the well-known passenger dining tables.  

This is especially true if according to a preferred off leadership example at least one of the individual chambers largely empty, preferably empty.

Moving away from the thought, the volume between the top plate, Bottom plate and all-round edge of the table top completely fill, as in the prior art through the rigid foam Inlay in this volume according to the invention is a large number preferably provided by all empty individual chambers. As a result, a considerable weight can be saved. The Weight saving can be compared to that described above NEN known passenger dining tables up to 200 g / table top gene.

Airless single chambers can be particularly in the so-called Make vacuum injection molding. The top plate and Un terplatte made parallel to each other and then in a vacuum room automatically with airtight sealing conclusion of the individual chambers connected. For the far however, the vast majority of use cases are complete sufficient if the individual chambers are filled with air.

The partition walls preferably divide the volume into a lattice largely evenly.

With this measure it is achieved that selectively on the upper plate or the sub-plate occurring pressure forces evenly distributed and derived. Furthermore - if sufficient narrow grid spacing and appropriately selected material strength - deflections from top plate or bottom plate closed.  

It is particularly preferred if the distance between parallel dividers generally 2 cm to 10 cm in front is preferably 3 cm to 7 cm and in particular 4 cm to 6 cm.

It has been shown that such distances are an ideal compro measure between the lowest possible "filling" of the volume Partitions on the one hand and sufficient stability on the other on the other hand.

According to a further preferred embodiment, the table is plate generally rectangular, and the partitions are slanted to the edges of the table top.

This measure allows the table top to bend Longitudinal or transverse direction are better included, this Stresses that occur in the material are therefore lower.

It is particularly preferred if at least one plate of Top plate and bottom plate a molded, upright Edge that is taken by itself or together with a corresponding edge of the other plate the circumferential edge of the Tabletop forms, and if at least one tabletop from upper plate and base plate as a multi-wall sheet molded, upstanding webs is designed for itself taken or together with corresponding bridges of the others Plate form the partitions.

In this embodiment, the edge as well as the partitions each an integral part of the top plate and / or bottom plate, so that the passenger dining table according to the invention from only can consist of two parts.  

It is particularly preferred if an upper side of the webs is provided with clip depressions or projections and if an opposite side of the other plate or a ge opposite top of the corresponding webs of the others Plate with corresponding clip protrusions or recesses is provided.

This measure allows the top plate and bottom plate to be separated made from each other and then clipped together the. Provided the clip connections are strong enough can be glued or welded from the top plate and bottom plate in the area of the peripheral edge become. In this case, the passenger dining table was special easy to use because the table top by loosening the clips connections can be easily separated from the folding mechanism can.

For reasons of stability, however, it can also be provided that Top and bottom plates in the area of the peripheral edge irreversible Sibel to connect with each other, even if appropriate clips connections are provided. Prevent the clip connections in this case that not excluded in an airplane Vibrate the top plate and bottom plate against each other gene.

According to a further preferred embodiment, each Longitudinal guide for a carrier of the folding mechanism by little at least two individual guides in a row, the two each parallel to the side edges of the table top fend, upstanding web sections.  

Through the measure, the tubes that have been customary so far are continuously piped shaped longitudinal guides through separate individual guides set, and these individual tours in turn essentially by means of web sections which can be formed on the top plate or bottom plate it is not absolutely necessary to form the longitudinal guides to be provided as separate elements. Ideally, the longitudinal ones guided tours integral part of upper and / or lower plate.

However, it is particularly preferred if the web sections in Ver longitudinally at the end with inward shoulders see and are spaced so far in the transverse direction that a Guide insert with a continuous opening for receiving of the wearer between the web sections and the shoulders is settable.

By the measure, a direct contact between the carriers the folding mechanism and the ge from top plate and bottom plate Avoid formed table top by using special guides kits can be provided for top plate and bottom plate comparatively brittle materials are also provided, the have a comparatively high strength. As material for The guide inserts offer a material that is less brittle and therefore more suitable as storage material. Further should the material of the guide piece with respect to the mate rial of the wearer of the folding mechanism for the smallest possible cause friction.

It is also preferred if the web sections directly into the Pass over the webs to form the partitions.  

In other words, the individual tours are also through Upper plate to lower plate extending webs formed to Strength and stability of the table top contribute. Close In this way, the guide elements as well as the Bridges to form the partitions in one operation Form in pieces with the top plate and / or bottom plate.

The material thickness of top plate, bottom plate, all-round Edge and partitions are in a preferred embodiment Example 1 to 5 mm, preferably 1.3 to 3 mm and esp special 1.5 to 2.5 mm.

It has been shown that such material thicknesses are ideal len compromise between light weight, high pressure stability and represent easier processability.

In Fig. 1, a passenger seat is generally designated 10. The passenger seat 10 is part of a row of seats of an aircraft and has a backrest 12 . A passenger dining table 20 is fixed on the back of the backrest 12 .

The passenger dining table 20 has a folding mechanism 22 , by means of which a table top 24 is fastened to the back of the backrest 12 . The passenger dining table 20 fixed to the seat 10 can be used by a passenger who is sitting behind this seat 10 . In the folded state, the table top 24 is approximately parallel to the backrest 12 . In this state, the passenger sitting behind can get up, read the newspaper, etc. In some passenger dining tables 20 , a fold-out cup holder 26 is provided on an underside of the table top 24 , as is indicated schematically in FIG. 1, so that the passenger is also folded down Table top can place a drink. The table top is folded down for eating, as shown for the seat 10 of FIG. 1.

In FIGS. 2 and 3, a first embodiment of a table top is a passenger-dining-table according to the invention shown 24 20.

The table top 24 has an approximately rectangular top plate 30 and a likewise approximately rectangular bottom plate 32 made of a flat plastic material. It is understood that the plastic material is approved for aircraft construction.

The upper plate 30 and the lower plate 32 are connected to each other at a umlau fenden edge 34 , as is indicated schematically by a joint 36 , namely by gluing, cold welding or the like.

The circumferential edge 34 comprises a front edge 34 a, a rear edge 34 b and two side edges 34 c.

The top plate 30 serves as a support plate for drinks and food. A special beverage recess 38 is provided for drinks, as is already known per se.

In the area of the front edge 34 a, the top plate 30 is also provided with an upwardly projecting slide barrier 40 , which prevents trays placed on the top plate 30 from sliding onto the lap of a passenger sitting behind them.

In the area of the rear edge 34 b, a tongue 42 aligned with the top plate 30 protrudes rearward relative to the rear edge 34 b. The tongue 42 is used in a conventional manner for coupling with the folding mechanism 22 .

The lower plate 32 has in the region of the front edge 34 a an approximately circular segment-shaped recess 46 , which also serves in a manner known per se to accommodate a pivotable fastening bolt in the folded state on the backrest 12 .

Between the top plate 30 and the bottom plate 32 , concealed longitudinal guides 50 are provided, which run approximately parallel to the side edges 34 c and for receiving carriers of the folding mechanism 22 not shown in FIGS. 2 and 3, the NEN. For this purpose, the longitudinal guides 50 are accessible via corre sponding openings 48 in the rear edge 34 b of the table top 24 .

In Fig. 3, the lower plate 32 is partially cut free and gives a view of a plurality of grid-like arranged webs 52 which extend from the inside of the upper plate 30 to the inside of the lower plate 32 . The webs 52 bil the partitions 52 of individual chambers, into which the volume formed by the upper plate 30 , lower plate 32 and circumferential edge 34 is largely evenly divided.

The webs 52 can be formed on the top plate 30 , the bottom plate 32 or partially on both plates 30 , 32 . Due to the web-like grid structure in the manner of honeycombs, an extraordinarily stable overall structure of the table top 24 is sufficient. At the same time, the total weight of the table top 24 is extremely low, since the individual chambers 54 usually remain empty. However, it is not excluded that individual chambers with filling elements, for. B. made of rigid foam, who provided, if this is necessary locally for reasons of stability.

As a rule, the webs 52 are completely connected in one piece with a plate of upper plate 30 and lower plate 32 . Then it is preferred if the other plate has a higher upstanding edge and thus forms a larger part of the peripheral edge 34 . In the illustration of Fig. 2 and 3, the webs 52 are provided integrally with the top plate 30 and protrude from the inside thereof before. The circumferential edge 34 , however, is largely formed by a raised edge of the lower plate 32 . Thus, both top plate 30 and bottom plate 32 have a sufficiently high inherent stability even when not connected to one another.

It goes without saying that the webs 52 are adapted to the outer shape of the upper plate 30 and lower plate 32 , in particular to the beverage recess 38 , the locking recess 46 and an optionally provided beverage holder 26 . The beverage holder 26 has a bracket with a circular hole in which a cup or the like can be used. The bracket can be folded into a recess in the lower plate 32 , so that the upper side of the sen is approximately flush with the upper side of the lower plate 32 .

The longitudinal guides 50 can also be formed, at least in part, by webs 52 .

In the illustrated embodiment, longitudinal webs 52 a of the webs 52 run approximately parallel to the side edges 34 c in the horizontal direction, and transverse webs 52 b run approximately parallel to the front or rear edge 34 a, 34 b.

In the vertical direction, that is between the top plate 30 and the bottom plate 32 , the webs 52 all run approximately parallel to the edges 34 .

A further embodiment of a table top of the passenger dining table 20 according to the invention is shown in more detail in FIGS . 4 to 7.

Unless otherwise stated, the same elements as in the embodiment of FIGS. 2 and 3 are provided with the same reference numerals.

The table top shown in FIGS. 4 to 7 also has an upper plate 30 and a lower plate 32 .

The lower plate 32 , which is shown in FIG. 4, has a circumferential, upstanding edge 60 . The edge 60 comprises a front edge 60 a, a rear edge 60 b, and c two side edges 60th

In the area of the rear edge 60 b two half openings 62 are seen before, which form part of the openings 48 for the longitudinal guides 50 .

The top plate 30 is also provided with a peripheral, upstanding edge 70 . The edge 70 has a leading edge 70 a, a rear edge 70 b and two side edges 70 c on.

The edges 60 , 70 together form a peripheral edge 34 in the assembled state.

The upstanding edge 70 of the top plate 30 is also provided with a circumferential shoulder 72 , the depth of which corresponds to the thickness of the projecting edge 60 of the bottom plate 32 . The upstanding edge 60 and the upstanding edge 70 are also dimensioned such that the upstanding edge 60 of the lower plate 32 can be pushed relatively snugly onto the upstanding edge 60 of the upper plate 30 until it abuts the circumferential shoulder 72 . In the area of the circumferential shoulder 72 , a joint running around it can then be seen, such as the joint 36 in FIGS. 2 and 3. The outer sides of the edges 60 , 70 are flush with one another.

The rear edge 70 b of the top plate 30 is also provided with two openings 48 , each of which runs ver across the shoulder 72 . Therefore, only corresponding half openings 62 are provided on the lower plate 32 .

In this embodiment, the webs 52 are not aligned in the horizontal direction parallel to the edges 34 a, 34 b, 34 c or to the edges 60 , 70 , but rather obliquely thereto, namely at an angle of 45 °. The webs 52 are arranged in the manner of a lattice and run crosswise parallel with constant lateral distances, so that individual chambers 54 of square cross section are formed.

The distance X from parallel webs 52 is 5 cm in this embodiment. The material thickness Y of the webs 52 , as well as the top plate 30 , bottom plate 32 and circumferential edge 34 is 2 mm in each case.

In Fig. 5a stages 74 are visible in which the height of the webs 52 is reduced by about half to the web height of the locking recess 46 adapted.

The longitudinal guides 50 are each formed by two guide bar arrangements 80 and a stop 82 ge in this embodiment.

The guide web arrangements 80 are formed from web sections running in the longitudinal direction, that is to say parallel to the side edges 34 c, between which an elongate carrier (not shown in FIG. 5) of the folding mechanism 22 can be inserted. The web sections are provided in the longitudinal direction at the end with inwardly directed shoulders 91 and spaced so far in the transverse direction from one another that a guide insert 84 can be inserted between the web sections 80 and the shoulders 91, which is seen with a continuous longitudinal opening ver for receiving the carrier .

The guide inserts 84 are inserted from above between the web sections 80 and the shoulders 91 before the lower plate 32 is connected to the upper plate 30 . The guide inserts 84 are then immovably held by this guide web arrangement 80 . The guide inserts 84 can be made from a different material than the plates 30 , 32 , in particular from a low-friction material suitable as a bearing for a metal carrier.

In Fig. 5a it is shown that two such guide web arrangements 80 are each located in the region of the openings 48 and approximately halfway between the front edge 34 a and the rear edge 34 b. A stop 82 , which is also formed by a web section, limits the depth of insertion of the carrier between the upper plate 30 and lower plate 32nd

The web sections 80 , 82 merge directly into the webs 52 .

Between two opposite shoulders 91 there are transverse webs 90 , the height of which is much lower than that of the webs 80 , 52 . Alternatively, there can be no web at all in the area of the cross webs 90 .

In order to ensure that the carrier passes through from the opening 48 to the stop 82 , the webs 52 are provided with corresponding web openings 92 in the area of this alignment line, as is shown in detail in FIG. 9.

Fig. 6 shows the top plate 30 and the bottom plate 32 in the assembled state. It can be seen that the peripheral edge 34 is flush with the outside due to the special design of the edges 60 , 70 .

Fig. 7 shows a sectional view along the line VII-VII of Fig. 6. In Fig. 7 can be seen in detail of the enclosed between the Stegabschnit 80 80 guide insert 84 , and a through a continuous opening of the guide insert 84th carrier 86th

FIG. 8 shows a view similar to FIG. 7, but with an alternative embodiment of a guide web arrangement 80 '.

The top plate 30 'and the bottom plate 32 ' are provided between the web sections 80 'each with lower, longitudinal guide webs 88 , so that the carrier 86 can be guided by the web sections 80 ' and the guide webs 88 or guide ribs 88 . In this alternative form exporting approximately no separate guide inserts 84 are necessary.

Fig. 10 shows the detail X of Fig. 5a. It can be seen that four webs 52 which run towards one another in a cross shape are connected in a web node 96 which is approximately ring-shaped in plan view. On the one hand, this prevents material accumulation. On the other hand, a clip recess 98 is thereby formed, into which corresponding clips projections 100 can be clipped in, which can be provided on the inside of the lower plate 32 , as is shown schematically in FIG. 11.

Such a clip arrangement enables the lower plate 30 and the upper plate 32 to be connected to one another by clips, so that it may be possible to dispense with gluing or welding the edges 60 , 70 in the region of the joint 36 .

The clip arrangement shown in FIGS . 10 and 11 is shown by way of example only. It goes without saying that other clip arrangements, for example with U-brackets protruding from the inside of the lower plate 32 , can be provided which encompass the webs 52 . It is of course also conceivable to provide corresponding projections on the webs 52 and corresponding depressions on the lower plate 32 .

An alternative clip arrangement is shown in FIG. 12. In this embodiment, the top plate 32 "has a plurality of short bars 52-1 . The bottom plate 30 " has a corresponding plurality of short bars 52-2 . The short webs 52-1 , 52-2 together form webs 52 , the shape and arrangement of which can correspond to the webs 52 of the previously described embodiments.

Clip springs 102 or, in other words, clip projections 102 running continuously along the end edges are provided on the end edges of the short webs 52-1 . Accordingly, 52-2 clip grooves 104 are hen hen on the end edges of the short webs.

When the top plate 32 ″ and the bottom plate 30 ″ are placed on top of one another, the clip springs 102 are clipped into clip grooves 104 . Since the connection of the lower and upper plate 30 ", 32 " is thus created by a large number of elongated clip arrangements, an extraordinarily solid, permanent clip connection between the lower and upper plate 30 ", 32 " is created, which is also possible in the event of impacts, blows etc. does not open.

It goes without saying that the clip springs 102 and the clip grooves 104 can also be provided directly on either the lower or the upper plate 30 ", 32 ", namely when the webs 52 are formed on the respective other plate.

In general, it is also entirely conceivable to provide a grating made of webs 52 and to clip a top plate provided separately from it and a bottom plate separately provided from it onto the top and bottom of the grating.

In the embodiment of FIG. 12, the height H of the shorter short webs 52-1 is, for example, 2-8 mm, in particular 5 mm. The short webs 52-2 can be three times as high, for example. The thickness of the webs 52 formed from the short webs 52-1 , 52-2 is 1.5-2 mm in this embodiment. The top plate 32 "and the bottom plate 30 " have approximately the same thickness.

The lower plate 32 and the upper plate 30 are preferably produced by injection molding.
