In addition, the invention relates to a piece of furniture with such a flap insert.

2. Description of the prior art

It is known from the prior art for pieces of furniture, in particular office furniture, to use inserts with flaps, which make it possible, for example, to store objects in the pieces of furniture that are easily accessible from a work surface of the piece of furniture or to provide a cable inlet and outlet, for example Provide power supply for electrical devices on the piece of furniture.

In the case of desks and conference tables, there is usually a basket or the like as part of, in or under the flap insert for the power supply of electrical devices, to which a single socket or a plug-in strip is attached, which is connected to the power supply and to which One or more power cables can be connected to easily power an electrical device such as a laptop during daily work or at conferences. Other types of connection such as network or video/audio connections as well as switching elements can also be provided in a flap insert.

Typically, such flap inserts are inserted into the piece of furniture in such a way that the flap protrudes approximately 3-5 mm above the work surface of the piece of furniture. However, solutions are also known in which the flap is flush with the work surface of the piece of furniture, i.e. they essentially form one surface and there are no steps.

Typically, flap inserts have a flap that is pivotable about a single fixed pivot axis toward an opening side.

In order to increase flexibility and to have access to the flap insert from more than one side, the DE 10 2013 000 826 A1 a flap insert is known in which the flap interacts at four bearing points with magnets attached to a frame of the flap insert. With the solution described there, the flap can be opened on four sides. The disadvantage of this, however, is that the magnets have to be comparatively strongly magnetized so that the magnets on the sides that are not open work reliably as bearings. The associated large forces can cause damage to the flap itself or the magnets can burst, which can result in sharp-edged fragments that pose a potential risk of injury to the user.

The US 8,925,469 B2 In contrast, describes a variant in which there are recesses within the flap insert into which rotating pins that are connected to the flap can engage. The flap can thus pivot about two pivot axes into two opening positions. The disadvantage of this is that the pivot pins can slide out of the recesses and the flap can therefore be accidentally removed. This means there is a risk that the flap will fall back into the recesses after each use has to be used, which is annoying in daily work.

From the JP S60- 90 042 U A center console box between the driver's seat and the passenger seat of a car is known, in which the lid can be opened on both sides. The cover has clip elements on both sides with a spring section, so that the clip elements can snap onto bearing pins in the center console box, which then come to rest in corresponding recesses in the clip elements. If the lid is opened on one side, the clip elements can be rotated around the bearing pins on the other side.

Further state of the art is from the publications DE 196 05 0541 A1 , DE 10 2005 055 138 B4 , DE 31 11 595 A1 and DE 835 640 B known.

SUMMARY OF THE INVENTION

The object of the invention is therefore to provide a flap insert for a piece of furniture and a piece of furniture with such a flap insert, which are improved in comparison and in particular address the disadvantages of the prior art explained above. In particular, the flap should not wobble and/or wobble in a direction parallel to the pivot axes.

The task is solved by a flap insert for a piece of furniture according to claim 1.

The inventors have recognized that in the bearing and counter-bearing variants according to the invention, the flap is attached to the frame in such a way that it has a tight fit during normal opening and closing operation, i.e. when it pivots within the pivoting ranges or is in one of the opening positions and storage and counter-support do not accidentally lose contact with each other. With flap inserts known from the prior art, there is sometimes the problem that the flap can become detached from the flap insert if used carelessly, which makes it necessary to reinstall it on the flap insert.

If a spring section is arranged at each recess, the bearing pins are received and locked in the recesses in the manner of a snap lock. By applying a counterforce that overcomes the locking force of the respective snap fasteners, the flap can be completely removed, for example for maintenance purposes or if the flap is to be replaced.

However, if the bearing pins have lugs and stop structures are arranged in the recesses, it is also possible to essentially prevent a linear movement in a direction perpendicular to one of the pivot axes between the flap and the frame when the flap pivots into one of the opening positions. Because of a pivoting movement, for example around the first pair of bearing pins, the lugs there act like a lock on the stop structures of the recesses, so that the first pair of bearing pins cannot leave the recess and so the first pivot axis remains locked. Conversely, when the flap is opened on the other side, the lugs of the second pair of bearing pins act as a latch to lock the second pivot axis.

In other words, in this case the flap is locked against removal during normal opening and closing operations by means of the stop structures for the lugs. Unlike the variant according to the invention without lugs, removing the flap without destroying parts of the flap insert is only possible if it is in a closed position.

Both the snapping into spring sections and the nose locking are preferably combined in order to guide the flap as securely as possible around the respective pivot axis of the non-open side.

The first and second pivoting ranges of the flap can also be limited by means of the stop structures for the lugs. By limiting the pivoting ranges of the flap, fixed opening positions are defined, which gives the user of the flap insert a feeling of a higher quality of the flap insert.

On the other hand, the stop structures also prevent the flap from pivoting further beyond the specified opening positions and thus losing contact with the bearing pins. This ensures that the flap can only be removed when it is in a closed position and a force applied uniformly from at least two sides is applied so that it can be lifted away from the pins at the same time. However, if the flap is in a pivoting movement or in one of the two opening positions, it cannot be removed due to the stop structures and the lugs.

A consequence of the two pivot axes is that the flap or the frame, depending on where the bearing and the counter bearing are arranged, in the first opening position of the flap and when it pivots in the first pivot range does not work with the second pair of bearing pins and in the second Opening position of the flap and when it pivots in the second pivot range it is not in contact with the first pair of bearing pins.

In one embodiment, the frame of the flap insert can comprise a circumferential frame on which the bearing with the bearing pins or the counter bearing with the pivot units can be formed. But it can also be divided into two or even further divided, for example with regard to the first page and the second page.

The bearing pins can be formed in one piece on the circumferential frame or connected to it by gluing, welding or by a fastening means such as screws or rivets and thus form the bearing. In the same way, the bearing pins can of course also be connected to the flap and thus form the bearing on it.

The frame can have a basket or a tray which is formed in one piece on the circumferential frame or is connected to it as a separate part in order to store, attach to or allow objects such as a socket or a power strip therein. However, the basket or tub can also be attached directly to a surface of the piece of furniture, in particular to a surface opposite the work surface of the piece of furniture (i.e. from “below”). Preferably the frame comprises a metal material. But it can also have a wooden material or a plastic material.

The first and second pivot axes preferably run parallel to one another and parallel to a main or longitudinal axis of the frame. The two pivot axes then preferably also run perpendicular to a first and a second transverse wall section of the frame, which in turn run perpendicular to a first and a second longitudinal wall section of the frame.

When installed in the piece of furniture, the flap has a top side (“top”) that is directed towards the ceiling and a bottom side (“bottom”) that is directed towards the floor when the flap is in a closed position, because the for The work surface in the piece of furniture provided for the flap insert often runs essentially horizontally in the room. The flap insert can of course also be provided on vertical or sloping furniture surfaces. The terms “top” and “bottom” then refer to the access side or the device side of the flap that is away from it.

Preferably the top of the flap is substantially flat.

The swivel units are preferably present on the underside of the flap, whereby the counter bearing is formed. The swivel units can also be connected to the frame and thus form the counter bearing there. The pivoting units can be connected to a cover layer of the flap, which is preferably made of a wooden material, by screwing or gluing. However, the pivoting units are particularly preferably connected to an intermediate layer by screwing or gluing and the cover layer in turn is connected to the intermediate layer by screwing or gluing.

The pivoting units can preferably be made of plastic, for example by injection molding. However, it is also possible to manufacture the swivel units from a metal or wooden material.

The cover layer preferably defines a first end of the flap disposed on the first side and a second end disposed on the second side. The pivoting units are preferably arranged at these ends and end flush with the cover layer. Alternatively, the pivot units are arranged on the frame and form the counter bearing, such that the pivot units are not visible when the flap is in the closed position.

1. a) der Eintrittsbereich sich aufeinander zu erstreckende Eintrittsflächen aufweist, die einen sich verjüngenden Eintrittsschacht für den entsprechenden Lagerstift ausbilden, und/oder
2. b) die Gegenlagereinsackung eine den entsprechenden Lagerstift berührende Gegenlagerfläche aufweist, die einer Form des Grundkörpers des entsprechenden Lagerstifts im Wesentlichen komplementär entspricht.

Insbesondere kann die Gegenlagerfläche eine Rundung aufweisen und, wenn der Grundkörper der Lagerstifte zylindrisch ist, kreisförmig ausgebildet sein. Möglich ist aber ebenso, dass die Gegenlagerfläche eckig ausgeführt ist. Dies kommt insbesondere dann in Betracht, wenn die Lagerstifte selbst drehbar gelagert sind und es somit nicht darauf ankommt, dass zwischen den Schwenkeinheiten und den Lagerstiften eine relative Schwenkbewegung möglich ist.Preferably, the recesses each have an entry area and a counter-bearing pocket, whereby

1. a) the entry area has entry surfaces that extend toward one another and form a tapered entry shaft for the corresponding bearing pin, and/or
2. b) the counter-bearing pocket has a counter-bearing surface that touches the corresponding bearing pin and which essentially corresponds to a shape of the base body of the corresponding bearing pin.

In particular, the counter bearing surface can have a curve and, if the base body of the bearing pins is cylindrical, can be circular. However, it is also possible for the counter bearing surface to be angular. This comes into consideration in particular when the bearing pins themselves are rotatably mounted and it is therefore not important that a relative pivoting movement is possible between the pivot units and the bearing pins.

Preferably, the recesses each have a transition edge at which the entry area and the counter-bearing pocket merge into one another, with a maximum width W1 of the counter-bearing pocket being greater than a width W2 of the entry area at the transition edge. Such a design is advantageous because the bearing pins, if they have a larger diameter than W2, can only slide into and out of the counter-bearing pockets of the recesses with increased effort. This creates a simple and technically effective way to snap the bearing pins into the recesses.

Preferably, the spring sections are each formed in the pivot units. In particular, the spring sections are formed in one piece in the pivot units.

Preferably, the spring sections in the pivot units are each formed by a slot-shaped indentation adjacent to the recesses.

If the second variant according to the invention is implemented alternatively or additionally, it is advantageous if the stop structures in the recesses of the pivot units are designed in such a way that a cover layer of the flap in the first opening position and in the second opening position has an angle of 60° to 100°, preferably from 70° to 90°, particularly preferably from 75° to 85° and most preferably from exactly 83°, to a plane in which the main or longitudinal axis of the frame lies.

Preferably, in the second variant according to the invention, there is an indentation in each of the recesses into which the nose of the corresponding bearing pin can slide when the flap is pivoted into the first or second opening position.

The indentations are preferably designed in such a way that the flap is locked in the first or second opening position, the locking taking place in particular in the manner of a detent as soon as the noses of the bearing pins have slipped into the indentations.

Adjacent to the indentations, a threshold in the form of a comparatively slight elevation can also be arranged on the pivot units, so that additional force must be applied so that the bearing pins can slide into the indentations and out of them again. The user of the flap insert thereby receives haptic feedback for locking or locking the flap in one of the opening positions.

The flap can thereby be brought from the first or the second opening position into a closed position by applying a closing force to the flap in a closing direction that overcomes the locking effect or in particular the locking effect of the noses of the bearing pins in the indentations. If a threshold is present, the force that must be applied to overcome the locking or latching effect can correspond to the force that must be applied to overcome the threshold when assuming one of the opening positions.

The main or longitudinal axes of the base bodies can preferably each extend perpendicular to a main plane of the corresponding transverse wall section of the circumferential frame of the frame. The main plane is to be understood as a regression plane that extends along a longitudinal direction of the transverse wall section. The main or longitudinal axes of the base bodies can also extend at an angle to the main plane of the transverse wall section. The noses can each extend over the entire length of the base body. However, it is possible and preferred for the lugs to be arranged at the end, i.e. on a side facing away from the respective transverse wall section of the frame.

Preferably, the pivot units of the flap each have a clamping sliding radius at their front ends, which works together with a flap stop on the bearing.

The clamping sliding radii are designed in such a way that the distance between the end faces of the swivel units and the swivel axis gradually increases. When the flap is opened, the front surface gets jammed on the flap stop at some point. The flap can thus be held in an open position. This also cushions the impact of the flap when opening. This minimizes the risk of damage caused by the swivel units when one of the opening positions is assumed on other parts of the flap insert or the piece of furniture in which the flap insert is to be installed.

Preferably, a single closing strip or a first and a second closing strip are provided on the frame, which lie opposite one another on two sides of the flap, with the one or two closing strips each closing a gap between the flap and the frame.

The one or two closing strips have the function of otherwise commonly used brushes: they close one or two gaps in a visually appealing way and allow cables to be guided under the flap in a visually appealing manner, so that only a minimum of the cable itself remains visible , namely the part that extends from the device to be connected to the flap. One advantage of locking strips compared to brushes usually used is that the user receives a visually and tactile impression of higher quality, which is particularly relevant for furniture in the higher price sector.

Preferably, the one or two locking strips are then each connected to the frame with at least one spring-loaded hinge and can be pivoted, the spring-loaded hinge specifying a closing position of the one or two locking strips, which they assume when no opening force acts on them .

It is also possible and conceivable, additionally or alternatively, for the one or two closing strips to have cable bushings that can be at least optically closed.

Preferably, the flap projects at least in sections beyond the one or two closing strips of the frame. The closing strip can hit the strip stop surface. Furthermore, when the flap is in the closed position, any impact of the flap on the closing strips can be dampened.

In particular, if the closing strips have a cover that is sensitive to stress, such as leather or a coating, such a design is particularly advantageous.

The bearing is preferably arranged on the frame and has a flap stop arranged next to at least one, in particular next to each, bearing pin.

Such one or more flap stops ensure that the flap cannot pivot further after assuming one of the opening positions or the closed position if the flap comes to rest on the flap stop. In such an embodiment, in the case of the second variant according to the invention, a further mechanical lock is provided in addition to the stop structures in the recesses of the pivot units, which overall ensures better handling and stability of the flap. This is particularly advantageous if the bearing is arranged on the frame and the counter bearing is arranged on the flap.

According to the invention, the bearing has a guide element arranged next to at least one, in particular each, bearing pin, the at least one guide element interacting with a corresponding guide surface of one of the pivot units.

At least one such guide surface improves the guidance of the flap during the pivoting movement. In particular, it is ensured that the flap is fixed in a direction parallel to the pivot axes when opening into one of the opening positions and therefore does not wobble and/or wobble. This is particularly advantageous if the bearing is arranged on the frame and the counter bearing is arranged on the flap.

According to a further aspect of the invention, the above-mentioned object is also achieved by a piece of furniture with a flap insert with some or all of the features described above for the flap insert.

Regardless of the above inventive idea of the flap that opens on both sides and can only be removed in the closed position, the closing strip is an independent idea. Features that relate to the closing strip are therefore also explicitly disclosed independently of the disclosure in the specific context of the flap insert according to the invention.

According to an independent inventive concept, a piece of furniture is disclosed which has a flap insert, the piece of furniture having a recess in which at least one locking strip and in particular a further locking strip opposite this are arranged, the locking strip being secured by means of at least one spring-loaded hinge Can be pivoted towards the bottom, wherein the closing strip can be made in particular from a metal and in particular can be covered with a layer of a fabric, artificial leather or leather material.

Although the advantages according to the invention are particularly evident in a flap that can be opened on two sides, the explained features and details of the components can also be applied to a flap that only opens on one side. In this regard, the person skilled in the art would only have to provide only one pivot axis instead of two pivot axes.

DESCRIPTION OF PREFERRED EMBODIMENTS

The 1 until 10 schematically illustrate exemplary embodiments of two variants according to the invention of a flap insert, designated overall by 10, for a piece of furniture. The piece of furniture has not been shown for reasons of simplicity. This can be, for example, a sideboard, a desk or a conference table. In the case of a piece of furniture designed as a conference table, several such flap inserts 10 can also be present.

In the 3 until 6 an embodiment of a first variant of the flap insert 10 according to the invention is shown, in which 1 , 2 and 7 until 10 however, an embodiment of a second variant according to the invention.

Preferably, the flap insert 10 is completely embedded in a work surface of the piece of furniture that lies essentially horizontally in space, i.e. that there is essentially no difference in height between a top side 10a of the recessed flap insert 10 and the work surface of the piece of furniture. This can be achieved by fastening the flap insert 10 in a correspondingly tailored and corresponding hole in the piece of furniture from an inside of the insert 10b using fasteners on an inner surface of the hole.

The flap insert 10 in the present case has a frame 12 as well as a bearing and a counter bearing.

The frame 12 in turn has a surrounding frame 14. In the present exemplary embodiment, the circumferential frame 14 has a substantially rectangular shape and comprises two opposite transverse wall sections 16, which define a first side 18a and a second side 18b of the flap insert 10, as well as two opposite longitudinal wall sections 20. The storage is present arranged on the frame 12.

In exemplary embodiments not specifically shown, storage can also be provided elsewhere, as will be explained further below.

In the present case, the bearing has a first bearing section 22a on a first transverse wall section 16a of the rotating frame 14 and the bearing has a second bearing section 22b on a second transverse wall section 16b.

In the present case, the bearing sections 22a, 22b each provide two bearing pins 24a, 24b. The bearing pins 24a, 24b on the first side 18a form a first pair of bearing pins 26a and a second pair of bearing pins 26b with the bearing pins 24a, 24b on the second side 18b. The first pair of bearing pins 26a defines a first pivot axis S1 and the second pair of bearing pins 26b defines a second pivot axis S2.

Furthermore, the flap insert 10 has a flap 28. In exemplary embodiments not specifically shown, the bearing can also be arranged on the flap 28 in the manner of a kinematic reversal. In the present case, however, the counter bearing is arranged on the flap 28, which has a first pivoting unit 30a on the first side 18a and a second pivoting unit 30b on the second side 18b. In the present case, the pivoting units 30a, 30b each have two recesses 32a, 32b arranged correspondingly to the bearing pins 24a, 24b, into which the bearing pins 24a, 24b can engage. In the exemplary embodiments mentioned above and not shown, which are designed in the manner of a kinematic reversal, the counter bearing is not arranged on the flap 28, but on the frame 12.

The flap 28 can be pivoted about the first pivot axis S1 within a first pivot range towards a first opening side 34a and thereby brought into a first opening position (not provided with a reference number). In addition, the flap 28 can also be pivoted about the second pivot axis S2 within a second pivot range towards a second opening side 34b and thereby brought into a second opening position (not provided with a reference number).

Like from the 3 until 6 As can be seen, a spring section 35.1 is arranged on the recesses 32a, 32b of the pivot units 30a, 30b, by means of which the bearing pins 24a, 24b snap into the corresponding recess 32a, 32b.

In this exemplary embodiment, the recesses 32a, 32b each have an entry area 35.2 and a counter-bearing pocket 35.3 on. In the present case, the entry area 35.2 has entry surfaces 35.4 that extend towards one another and which form a tapered entry shaft 35.5 for the corresponding bearing pin 24a, 24b. The combination of spring section 35.1 and inlet shaft 35.5 ensures that the flap 28, once it has been locked, ie contact between the bearing and counter bearing has been established, can only be removed by applying a counterforce that overcomes the locking force of the spring section 35.1.

In addition, the counter-bearing pocket 35.3 in this case has a counter-bearing surface 35.6 that touches the corresponding bearing pin 24a, 24b. In the present case, the counter bearing surface 35.6 has a shape that corresponds essentially complementary to a shape of a base body of the corresponding bearing pin 24a, 24b. The base body will only be given a reference number subsequently.

The recesses 32a, 32b each have a transition edge 35.7, at which the entry area 35.2 and the counter-bearing pocket 35.3 merge into one another. In the present case, a maximum width W1 of the counter-bearing pocket 35.3 is greater than a width W2 of the entry area 35.2 at the transition edge 35.7.

In the present case, the spring sections 35.1 are formed in one piece in and with the pivot units 30a, 30b. In exemplary embodiments not specifically shown, the spring sections 35.1 are designed as a separate component and are connected to the pivot units 30a, 30b via connecting means. The spring sections 35.1 are each formed in the pivot units 30a, 30b by a slot-shaped indentation 35.8, which is arranged adjacent to the recesses 32a, 32b.

The structural features of the exemplary embodiment of the first variant according to the invention explained above also have the exemplary embodiment of the second variant according to the invention explained below. Below, only the differences between the two exemplary embodiments will be explained in more detail.

Like from the 7 until 10 As can be seen, in the exemplary embodiment of the second variant according to the invention, a stop structure 36 is provided in the recesses 32a, 32b, which has a stop surface 38 for the corresponding bearing pin 24a, 24b. The first and second pivoting ranges are limited by the stop structures 36. This means that the flap cannot pivot further beyond the outer limits of the pivoting ranges and thus in the fully open state, ie in the first or second opening position, in comparison to the closed position at a fixed angle to a plane in which a main, not shown, or longitudinal axis of the frame 12 runs.

In other words, the stop structures 36, which are arranged within the recesses 32a, 32b, each specify an angular range within which the flap 28 can pivot about the first and second pivot axes S1, S2. So that the stop structures 36 can effectively limit the pivoting ranges of the flap 28, it is preferred that the bearing pins 24a, 24b have a shape that deviates from a purely rotationally symmetrical shape.

In the present embodiment, the flap 28 of the flap insert 10 is designed such that the flap 28, when in the first opening position and when pivoting in the first pivot range, is not in contact with the second pair of bearing pins 26b. Likewise, when the flap 28 is in the second opening position and when pivoting in the second pivot range, it is not in contact with the first pair of bearing pins 26a.

So that the flap 28, when it has assumed one of the opening positions, does not move back into the closed position, for example, there is an indentation 40 in the recesses 32a, 32b, into which the corresponding bearing pin 24a, 24b can slide. when the flap 28 is pivoted into the first or second opening position. The indentation 40 goes in particular from the 8th out.

Due to the indentations 40, the flap 28 is locked or locked in this opening position when one of the opening positions is assumed as soon as the bearing pins 24a, 24b have slipped into the corresponding indentations 40. In the present exemplary embodiment, the indentation 40 is designed in such a way that the flap 28 can be brought into one of the opening positions with a uniform amount of force and out of these again into the closed position with a slightly increased amount of force. In other words, in the present case, the flap 28 can be brought from the first or second opening position into the closed position by overcoming the locking or latching effect of the bearing pins 24a, 24b in the indentations 40 in a closing direction that is opposite to a respective opening direction Closing force is applied to the flap 28.

However, a threshold in the form of a bulge can also be present adjacent to the indentation 40, through which a further slightly increased amount of force is required to assume one of the opening positions of the flap 28. As a result, a user of the flap 28 receives haptic feedback.

Like in particular from the 7 and 10 As can be seen, the bearing pins 24a, 24b in the present exemplary embodiment of the flap insert 10 each have a cylindrical base body 42 and a terminal nose 44, which essentially has the basic shape of a drop.

Longitudinal axes of the noses 44, which are not specifically provided with a reference number, each extend essentially perpendicular to longitudinal axes of the base bodies 42, which are also not provided with a reference number.

In exemplary embodiments not specifically shown, the base bodies 42 have a prismatic shape and/or the basic shape of the noses 44 are essentially rectangular. Likewise, in exemplary embodiments not specifically shown, the lugs 44 are not arranged at the ends, but extend, for example, over the entire length of the bearing pins 24a, 24b or only extend over a central axial region.

In any case, in the present exemplary embodiment, the bearing pins 24a, 24b do not slide into the indentations 40 as a whole, but rather only the lugs 44. The locking or latching effect in the opening positions is therefore more reliable and stable than if bearing pins 24a, 24b without lugs 44 as a whole Indentations 40 would slide in.

The pivot units 30a, 30b each have a first end 46a and a second end 46b, between which a strip body 48 of the pivot units 30a, 30b extends. In exemplary embodiments not specifically shown, the pivoting units 30a, 30b can also be a functional combination of individual elements, i.e. it is not necessarily necessary for such a strip body 48 to extend from the first end 46a to the second end 46b.

In the present case, the flap 28 has a strip stop surface 50 adjacent to each of these ends 46a, 46b. The strip stop surfaces 50 are made in particular from the 8th and 10 can be seen and are formed there as an oblique chamfer on an intermediate layer 60 of the flap 28.

Like in particular from the 1 , 7 and 10 As can be seen, the flap insert 10 has a first closing strip 52a and a second closing strip 52b, which lie opposite one another on two sides of the flap 28 and a first gap 54a and a second gap 54b, which are each arranged between the frame 12 and the flap 28 , close.

Closing the closing strips 52a, 52b means that they optically cover the spaces 54a, 54b between the flap 28 and the frame 12, so that the spaces 54a, 54b are not visible to the user of a piece of furniture in which the flap insert 10 is to be installed are visible.

However, the closing strips 52a, 52b do not have to be present together with the bearing and counter bearing on the flap insert 10. Instead, regardless of the inventive concept relating to the flap insert 10, pieces of furniture are also conceivable in which at least one closing strip 52a, 52b is present in the manner described above, but without the rest of the structure of the flap insert 10.

In the present exemplary embodiment of the flap insert 10, the closing strips 52a, 52b are each connected to the frame 12 with two spring-loaded hinges 56 and can be pivoted about a hinge axis defined by the hinges 56, which is not specifically provided with a reference number. The spring-loaded hinges 56 each specify a closing position for the closing strips 52a, 52b, which the closing strips 52a, 52b assume when no opening force acts on the closing strips 52a, 52b. The advantages of this are that the spaces 54a, 54b are automatically closed by the closing strips 52a, 52b and that, for example, cables that are guided over the closing strips 52a, 52b and under the flap 28 are fixed to the flap 28 from below.

In the present exemplary embodiment of the flap insert 10, the flap 28 is designed such that it projects beyond the closing strips 52a, 52b at least in sections. In the closed position of the flap 28, the closing strips 52a, 52b then rest on the strip stop surfaces 50 of the flap 28.

In the present case, the flap 28 is constructed in layers. In the illustrated embodiment, it has a cover layer 58, which preferably comprises a wooden material, and furthermore an intermediate layer 60, which preferably comprises a metal material, to which the pivot units 30a, 30b are attached. In the present case, the pivot units 30a, 30b are attached to the intermediate layer 60 by fastening means 62 in Shape of screws. However, dowels and/or glue, nails or rivets or the like can also be used.

The flap 28 projects beyond the closing strips 52a, 52b here with its cover layer 58 and its intermediate layer 60. The pivoting units 30a, 30b are arranged and dimensioned in such a way that when the flap 28 is pivoted into one of the opening positions or from these back into the closed position of the flap 28 do not come into contact with the closing strips 52, 52b.

In the present case, the bearing is also designed in such a way that a flap stop 64 is arranged on a side (“bottom”) of the bearing pins 24a, 24b facing away from the flap 28 next to each bearing pin 24a, 24b. In addition to the stop structures 36, the flap stop 64 represents a further mechanical obstacle for the flap 28, so that it is ensured as far as possible that the flap 28 always pivots into the same opening position.

For this purpose, the pivot units 30a, 30b have clamping sliding radii 49 at their front ends, which gradually interact more strongly with the respective flap stop 64 of the pivot axis when the flap 28 is opened about a pivot axis. That is, the clamping sliding radii 49 are designed in such a way that the distance between the end faces of the pivot units 30a, 30b and the pivot axis gradually increases. When the flap 28 is opened, the end face becomes jammed at some point on the flap stop 64 and can additionally hold the flap 28 in the open position.

Additionally or alternatively, the flap 28 can also abut the flap stop 64 with the intermediate layer 60 or the cover layer 58 in order to determine the opening position.

In addition, the frame 12 in this case has a guide element 66 arranged next to each bearing pin 24a, 24b. In the present case, the guide elements 66 have approximately a sickle shape and each protrude vertically from the transverse wall sections 16a, 16b. The guide elements 66 are arranged in such a way that their geometric center of gravity lies on a side of the guide elements 66 facing the bearing pins 24a, 24b.

The guide elements 66 cooperate with guide surfaces 67 which are provided in or attached to the pivot units 30a, 30b. In the present case, the guide surfaces 67 are each arranged on one side of the pivot units 30a, 30b, which faces the respective transverse wall section 16a, 16b of the frame 12. In other words, the interaction of guide elements 66 and guide surfaces 67 takes place in a space between the transverse wall sections 16a, 16b and the pivot units 30a, 30b, which is not provided with a reference number. In the present case, the interaction takes the form of contacting the guide elements 66 with the respective guide surfaces 67. A technical effect of this interaction is that a lateral wobbling movement in a direction parallel to the pivot axes S1, S2 is largely prevented.

In the present exemplary embodiment, a guide wall is also arranged within the recesses 32a, 32b. In the present case, the bearing pins 24a, 24b each engage behind these guide walls. This prevents the flap 28 from performing a linear movement in a direction parallel to one of the pivot axes S1, S2, for example when it is opened into one of the opening positions. In other words, these guide walls prevent the flap 28 from wobbling, which is a particularly important quality feature, especially in furniture of higher price categories.
