Description

[0001] This application is a divisional application of application number 2018800252013, application date April 11, 2018, and invention name "Furniture panels with movable panel accessories and cabinets and furniture items with such furniture panels". Technical Field

[0002] The invention relates to a furniture panel with an integrated or inserted flap fitting, comprising a lever mechanism with a plurality of levers for guiding a flap of an item of furniture. The flap fitting comprises a spring unit which acts on at least one lever of the lever mechanism, wherein the pretension of the spring unit is adjustable. The invention further relates to a furniture carcass or an item of furniture having at least one flap fitting. Background Art

[0003] Furniture, in particular kitchen furniture or living room furniture, such as base units or wall cabinets, generally has a furniture body that opens toward the front, on which a movable furniture part is mounted, guided via a fitting. In particular, in the case of wall cabinets, a flap is often used as a movable furniture part for closing the furniture body, which flap is mounted via at least one, generally two, laterally arranged flap fittings. The flap fitting enables an upward opening (upward pivoting) of the flap, wherein the flap can be pivoted, for example, about a horizontally extending imaginary pivot axis arranged in the upper region of the furniture body. Other upwardly directed opening movements of the flap are also conceivable.

[0004] The lever mechanism of the flap fitting is typically formed in several parts as a multi-joint lever mechanism, so that the so-called door bearing lever that fastens the flap performs a combined pivoting and sliding movement or pivoting movement, which takes place about a pivot axis that is located outside the flap fitting and generally also outside the furniture body.

[0005] A flap fitting with a lever mechanism and a spring acting on one of the levers is known from document CN 105155962 A. The spring holds the guided flap in the closed state and also in the fully open state by the application of force. The force to be applied by the spring to the lever mechanism, in particular in the open state, depends to a large extent on the geometry and weight of the guided flap. In order to ensure that flaps of different sizes and weights are reliably held in the open position, the spring pretension of the spring is settable. For this purpose, the bearing point of the spring can be adjusted via the spindle with respect to the housing of the flap fitting. The spindle is connected to a laterally accessible tool socket via a deflection gear. During the installation of the flap fitting on the side wall of the furniture body with the flap open, the pretension of the spring in the interior of the furniture body can be set by means of a screwdriver as a tool.

[0006] The described flap fittings are suitable for being mounted on the inner side of the side wall of the furniture carcass. However, in this case the fittings inevitably protrude into the interior of the furniture carcass, which on the one hand reduces the available storage space in the furniture carcass and on the other hand also impairs the structure of the interior of the furniture carcass. The mounting of the fittings also hinders the cleaning of the interior of the furniture carcass, in particular of the inner side of the side wall. In particular, for visual reasons, it is desirable to have side walls on which no fittings are mounted.

[0007] For mounting a door hinge, it is known to mill a cavity into the end face of a side wall, into which cavity the door hinge can be inserted from the front. In this way, a side wall with an integrated door hinge is provided, wherein the inner side of the side wall remains free. For example, a hinge suitable for such a milled cavity is known from DE 1 559 963.

[0008] Furniture walls with insertable or integrated fittings are also suitable for furniture with flaps due to the advantages mentioned. However, the flap fittings known from document CN 105 155 962 A are not suitable for integration or insertion into furniture walls because the setting of the spring pretension takes place from the side, which is not possible with side walls having a continuous inner surface. Summary of the invention

[0009] The object of the present invention is therefore to provide a furniture front for an item of furniture with an inserted or integrated flap fitting, in which the side surface can be made continuous and a simple setting capability of the pretension of the spring unit of the flap fitting is nevertheless possible. Another object is to specify a furniture carcass and an item of furniture with at least one flap fitting and the advantages listed.

[0010] This object is achieved by a furniture panel, a furniture carcass or a furniture item having the features of the respective independent claim. Advantageous embodiments and improvements are the subject matter of the respective dependent claims.

[0011] The furniture panel according to the invention is distinguished in that the lever mechanism retracts into the end opening of the flap fitting and the furniture panel in the closed position of the guided flap, wherein the pretensioning force can be set via an adjusting element with a tool receptacle and wherein the tool receptacle is accessible through the end opening into which the lever mechanism retracts.

[0012] The end opening is provided in the flap fitting and the furniture panel to accommodate the lever mechanism in the closed state of the flap. According to the invention, this opening is also used to set the pretension of the spring unit of the flap fitting and / or the transmission ratio between the spring element and the lever mechanism. The tool receptacle is arranged and aligned for this purpose in the flap fitting in such a way that it is accessible through the mentioned opening, thereby providing a setting capability without having to provide, for example, additional lateral setting openings. A continuous and uniform appearance of the side of the furniture construction panel is thus maintained.

[0013] In an advantageous embodiment of the furniture panel, the flap fitting comprises a spindle unit with a spindle, with which the spring bearing can be displaced, wherein the spindle is coupled to the adjustment element. The spindle is preferably coupled to the adjustment element via a bevel gear. Simple and tightly implementable adjustment options for the spring pretension are provided by the displacement of the spring bearing. Due to the bevel gear, setting can take place through the end opening of the furniture construction panel, even if the spindle extends parallel or diagonally with respect to the arrangement of the end face.

[0014] The spindle can in this case be dimensioned so that it can directly absorb the forces transmitted from the spring bearing. Alternatively, it is also possible to mount the spring bearing so that it can be linearly displaced in a guide rail arranged parallel to the spindle, so that the forces can be absorbed wholly or partly by the guide rail. The spindle can thus be dimensioned to be thinner. The guide rail can, for example, be formed in a U-shape.

[0015] In another advantageous embodiment of the furniture panel, the spring unit acts via a pressure roller on a control section of a lever in the lever mechanism, whereby the flap fitting is held in the closed and / or open end position. In this case, the intensity of the spring force acting on the lever mechanism and its direction can be precisely specified depending on the opening angle of the flap fitting via the shaping of the control section.

[0016] In a further advantageous embodiment of the furniture panel, the flap fitting comprises a housing comprising two parallel sides spaced apart from one another, for example formed by side panels. Preferably, in the closed state of the flap fitting, all joint axes of the lever mechanism are positioned between the sides. Thus a furniture panel is provided which does not impair the appearance of the furniture body due to the protruding components of the flap fitting. Furthermore, the sides preferably have an internal spacing which is less than 16 mm (millimeters) and preferably less than 14 mm. Despite the integrated flap fitting, the resulting furniture wall has a conventional furniture body wall thickness, which is important for the visual impression of the furniture item and also ensures unrestricted use of the machine tools used hitherto.

[0017] In another advantageous embodiment of the furniture panel, the sides of the flap fitting extend upwardly to the end opening of the furniture panel, which is particularly advantageous for reasons of strength of the furniture panel in the region of the opening. The sides can thus be used to support components of the flap fitting, for example a spindle unit is preferably fastened to at least one of the sides.

[0018] In another advantageous embodiment of the furniture panel, the flap fitting is inserted through the opening of the furniture panel into a slot formed behind the opening in the furniture panel. Alternatively, the flap fitting can be integrated into this slot during the production of the side wall. Furthermore, the flap fitting can alternatively be inserted laterally through a slot which is introduced from the side of the furniture panel and comprises an opening on the end face. In all mentioned cases, the mentioned opening through which the lever mechanism of the flap fitting extends is preferably formed in the front face of the furniture panel.

[0019] In a further advantageous embodiment, the furniture panel has no or virtually no difference in thickness in the region of the flap fitting and outside this region.

[0020] In a further advantageous embodiment of the furniture panel, the tool receptacle is accessible through an end face opening of the furniture panel, thereby providing a setting capability without providing an additional opening.

[0021] Alternatively, the tool receptacle can be set through an end opening of a furniture panel different from the end opening of the furniture panel that the lever mechanism mentioned above is retracted to. This is slightly more complicated, but also enables setting without damaging the sides of the furniture body.

[0022] In another advantageous embodiment of the furniture panel, a scale visible to the user is arranged on the adjustment element. Such a scale enables, for example, the spring pretension of the spindle unit to be pre-set to a specific predetermined value. Furthermore, the scale facilitates the identical setting of a plurality of flap fittings which jointly guide the flap.

[0023] The side wall for a furniture carcass according to the invention is distinguished by the use of at least one such furniture panel with an inserted or integrated flap fitting. The furniture item with a furniture carcass and a guide flap according to the invention is distinguished by such a furniture carcass comprising at least one such side wall with an inserted or integrated flap fitting. The advantages mentioned in connection with the flap fitting are obtained. In particular, a furniture item with a guided flap can be provided, the entire size of the interior of which can be used, which can be freely designed and has a visually attractive effect. The guided flap can be pivoted about an imaginary pivot axis extending horizontally and which is arranged in the upper region of the furniture carcass. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Respectively Figure 1a and 1b 2a and 2b, the flap (not shown here) guided by the flap fitting 1 is shown in the closed position ( Figure 1a , 1b ) and fully open position ( Figure 2a , 2b ) in a first instance of a flap fitting 1. Figure 1a and 2a An isometric illustration showing a flap fitting and Figure 1b and 2b A side view thereof is shown.

[0033] In the description, terms such as top, bottom, left, right etc. refer exclusively to the illustration selected by way of example in the corresponding figure. The terms front and rear generally refer to the opening movement of the guide flap. In this case, the front side is the side facing the user.

[0034] The housing 10 of the flap fitting is shown open on one side in each case to enable the internal structure of the flap fitting 1 to be explained. In all the figures, the same reference numerals identify the same elements. For reasons of comprehensibility, in the figures, not every element is provided with a reference numeral in all figures.

[0035] The housing 10 is formed in the present case by two side panels 11, of which only the rear one is shown in the figure. The side panels 11 are spaced apart from one another and aligned parallel to one another by a partial circumferential frame 12. A plurality of rivets 13 (see Figure 3a , 3b ) through the side panels 11 and the frame 12, the housing 10 and thus the flap fitting 1 are held together using the plurality of rivets 13. In addition to rivets, other fastening means may also be used, such as screws. The rivets 13 pass through the widened portion 121 of the frame 12.

[0036] In the described flap fitting 1 , all other components are fastened to the side panels 11 , for example also using rivets or bolts passing through one or both of the side panels 11 .

[0037] The flap fitting 1 comprises a lever mechanism 20 with five levers, which are connected to each other and / or to the housing 10 at seven joint points. The flap fitting 1 is therefore designed as a seven-joint hinge. The lever mechanism 20 comprises a door bearing lever 21 as the outermost element of the lever mechanism 20, which is connected to a mounting plate 31 via an adjustment device 30. The flap to be guided by the flap fitting 1 is mounted on this mounting plate 31. The adjustment device 30, which is described in more detail in the following figures, realizes the mounting plate 31 and thus guides the adjustment movement of the flap with respect to the door bearing lever 21.

[0038] Door bearing lever 21 Figure 1a , 1b The door bearing lever 21 is rotatably connected to a transmission lever 22 at an upper joint point in the figure. The door bearing lever 21 is connected to a deflection lever 23 in a lower joint point in the figure. The deflection lever 23 and the transmission lever 22 are in turn linked to a control lever 24. The transmission lever 22 is connected at its rear end to a support lever 25, wherein the support lever 25 is in turn rotatably mounted on the housing 10. This lever mechanism 20 thus results in a seven-joint chain.

[0039] As per Figure 2a and 2bIt can be seen that the levers of the lever mechanism 20 are shaped so that they form a suitably stretched arrangement in the open position of the flap. During the opening or closing process, the outer element of the lever mechanism 20 (i.e. the door bearing lever 21) performs a combined rotational and translational movement, whereby the mounted flap is not only pivoted but also moved forward so that it is guided so that its upper edge is above the upper body edge or the uppermost body edge.

[0040] The flap fitting 1 further comprises a spring unit 40, which keeps the flap in both the closed and fully open states by the application of a spring force. Specifically, in the fully open state, the spring unit 40 can counteract the weight of the flap, thereby maintaining it in the open position without further locking the lever.

[0041] In the illustrated exemplary embodiment, the spring unit 40 comprises a spring cavity 41 with a plurality of compression springs 411. In an alternative embodiment, the spring unit can also comprise only one spring instead of a plurality of springs. The spring cavity 41 is mounted on the right side in the figure in a fixed spring bearing 412. The spring cavity 41 is mounted on the left side in the figure in a free spring bearing 413 at the shorter end of an angled intermediate lever 43, wherein the intermediate lever 43 is formed as a double-sided lever and is mounted so that it can pivot on the housing 10. A pressure roller 431, which acts on the control part 221 of the transmission lever 22, is attached at the end of the second free lever arm of the intermediate lever 43. The fixed spring bearing 412 secures the right side of the spring cavity in the figure with respect to the housing 10. However, the position of this fixed spring bearing 412 can be adjusted by the spindle unit 42 to be able to set the spring pretension and also the direction of action of the spring cavity 41 on the intermediate lever 43. The additional words "fixed" and "free" with respect to the spring bearings 412, 413 refer to the positions of the spring bearings 412, 413 during the movement of the lever mechanism (20). The fixed spring bearing 412 maintains its position, and the free spring bearing 413 moves along the control portion 221 according to the movement of the pressure roller 431. The details of the spindle unit 42 are further explained below.

[0042] The control part 221 extends in a dome shape on its edge with rising (left side of the control part 221 in the figure) and falling flanks (right side of the control part 221 in the figure). When the pressure roller 431 presses against the falling flank, the pressure of the pressure roller 431 results in the result that the lever mechanism 20 is moved in the direction of the closed position. The installed flap is thus pressed closed or kept closed. When the pressure roller is exactly on the dome of the control part 221, the opening movement passes through the dead point. In the further course of the opening movement, the pressure roller 431 presses against the rising flank of the control curve, wherein the pressure of the pressure roller 431 results in the result that the lever mechanism 20 is further moved in the direction of the open position. The opening movement is thus assisted and the flap is held in the open position.

[0043] The spindle unit 42 comprises a spindle 421 which is mounted such that it can rotate in a first spindle bearing 422 (here the lower part) and a second spindle bearing 424 (here the upper part). Furthermore, a helical gear is arranged in the first spindle bearing 422, which transmits the rotational movement of an adjustment element having a tool receptacle 423 to the spindle 421, for example via mutually meshing bevel gears. The tool receptacle 423 (for example a slotted receptacle, a T-head receptacle, a hexagonal receptacle or a polygonal receptacle) is oriented forward in the direction of the open area of ​​the housing 10 and is accessible from there.

[0044] The two spindle bearings 422, 424 are fastened to the housing 10 using fastening means 425. The fastening means 425 are, for example, rivets which are guided through the two side panels 11 in the same manner as the rivets 13 so that the spindle unit 42 is arranged and fastened between the two side panels 11.

[0045] By rotating the spindle 421, the spindle nut 426 is moved along the spindle 421, wherein the fixed spring bearing 412 is formed on the spindle nut 426. Therefore, the rotational movement of the tool receptacle 423 and thus the adjustment element displaces the fixed spring bearing 412 along the spindle 421 and thus changes the spring pretension and the engagement direction of the spring unit 41 on the intermediate lever 43.

[0046] It should be noted that the adaptation of the spring action, with which the force is transmitted from the spring unit to the lever mechanism, can be effected not only by a change in the spring pretension but also alternatively and / or additionally by a change in the transmission ratio.

[0047] Furthermore, a damping unit 50 is provided, in the present case a linear damper operating as a compression damper, against which a part of the transmission lever 22, more precisely a part of the control portion 221 of the transmission lever 22, moves in order to decelerate the lever mechanism 20 when it approaches the closed state.

[0048] In principle, the damping unit 50 can also be arranged at another point inside the housing 10 and can act on another lever or arm of the lever mechanism 20 to slow down the flap approaching one of the end positions (closed / open) and thus damp it. In a refinement, two independent damping units 50 can also be provided, one of which performs closing damping and the other performs opening damping.

[0049] Due to the setting capacity generated by the spindle unit 42 and the setting process of the spring unit 41 Figure 3a , 3b and Figure 4a , 4b Shown in.

[0050] exist Figure 3a In the invention, the flap fitting 1 is used with Figure 2b The same way is described in the fully opened state of the door bearing 21 and / or the flap connected thereto. A setting tool 60 in the form of a screwdriver is inserted into the tool insertion hole 423 of the spindle unit 21. The shaft of the setting tool 60 passes through the opening of the housing 10 into which the lever mechanism 20 is inserted during the closing of the flap. Therefore, when the flap is open, the flap fitting 10 can be set from the end face of the flap fitting 10.

[0051] Figure 3b The flap fitting 10 is shown with a changed setting of the spring unit 40. In this position shown by way of example, the fixed spring bearing 412 has been set from the top ( Figure 3a ) is moved to the lowest setting. The spindle unit 42 enables the setting of any arbitrary intermediate position. The slope of the spindle 421 and / or the friction of the spindle nut 426 on the spindle 421 are selected so that the spindle unit 42 is self-restraining. The set intermediate position is thus maintained.

[0052] A change in the setting of the spring unit 40 changes the spring pretension of the compression spring 411 on the one hand and, due to the different angles at which the spring slot 42 acts on the intermediate lever 43, also changes the dynamics of the force action of the spring slot 41 on the lever mechanism 20. The manner in which these dynamics change and also the type of change in the spring pretension depends on the arrangement of the spindle unit 42 inside the housing 10. An arrangement of the spindle unit 42 parallel to the front edge of the housing 10 has proven to be particularly advantageous for the illustrated configuration.

[0053] exist Figure 4a and 4b In the closed position of the flap fitting 1, the spindle unit 42 is adjusted to Figure 3a and 3b . The adjustment of the retracting lever mechanism 20 is possible when the flap fitting 1 is not connected to the attached flap and also the mounting plate 31 is not arranged on the adjustment device 30 of the door bearing lever 21. If only the door bearing lever 21 of the lever mechanism 20 is retracted between the two side panels 11, a part of the opening of the housing 10 remains free in the lower area, through which the setting tool 60 can be guided. In this way, even if the flap is not attached, the spindle unit 42 can be preset to the desired setting, for example even before the flap is installed, and the desired setting only has to be slightly corrected thereafter.

[0054] The housing 10 having a closed housing 10, i.e. having a second side panel 11 attached Figures 1a to 2b Isometric view of the flap fitting in Figure 5a and 5b Shown in. Figure 5aThe flap fitting is shown in the closed state with the flap installed (not visible here) and Figure 5b The partially opened state is shown, with an opening angle of approximately 10°.

[0055] The housing 10 is closed in the region of the frame 12 by the above-mentioned rivets 13. It is obvious that instead of rivets 13, other connecting elements can be used to close the housing 10, for example screws. Alternatively, the closing of the housing can also be performed by bonding between the side panels 11 and the frame 12.

[0056] Figure 5a It is specifically shown that in the closed position of the flap fitting 1 the entire lever mechanism 20 including the adjustment device 30 is retracted between the side panels 1 .

[0057] Figure 6 A furniture panel according to the present application is shown, which forms a side wall 2 of a furniture carcass (not shown in greater detail), wherein a flap fitting 1 according to the present application is integrated into the side wall 2, for example Figures 1a to 3b The furniture carcass generally comprises at least two such side walls 2, wherein corresponding flap fittings 1 according to the invention are integrated into said at least two such side walls 2. These two flap fittings 1 (or possible further flap fittings 1 integrated into the middle wall of the furniture carcass) support flaps that close the furniture carcass towards the front.

[0058] The opening 4 through which the lever mechanism 20 of the flap fitting 1 extends is formed in the front face 3 of the side wall 2. The flap fitting 1 is inserted through the opening 4 during its production into a groove formed in the side wall 2 behind the opening or is already integrated into the side wall 2, or is inserted laterally through a groove introduced from the side 5 and including the opening 4 on the end face 3. In all cases, the flap fitting 1 is integrated into the side wall 2, wherein at least in the first two cases, the flap fitting is covered on both sides by the side 5 of the side wall 2 and is therefore not visible from the outside or from the interior of the furniture body. It is essential here that the flap fitting 1 and the side wall 2 form a unit and that there is no or almost no thickness difference with the side wall 2 into which the flap fitting is inserted.

[0059] In order to be integrated into the furniture panel or side wall 2 of the furniture body, the thickness of the flap fitting 1, i.e. the outer spacing of the side panel 11, is largely limited by the specifications relative to the wall thickness of the furniture body. For a typical side wall of a furniture body with a thickness of 16 mm (millimeters), the thickness of the flap fitting is necessarily less than 16 mm and preferably less than or equal to 14 mm. Therefore, the lever mechanism 20 containing the adjustment device 30 is formed so that it can be retracted between two side panels 11 with this spacing.

[0060] The side of the furniture panel or side wall 2 can thus comprise a continuous surface which is not interrupted by any element of the flap fitting 1. Specifically, this is achieved by the tool receptacle 423 of the flap fitting 1 being accessible through openings in the end face of the flap fitting and the furniture panel or side wall 2.

[0061] Figures 7a to 7c A second example of a flap fitting 1 is shown, which corresponds to the flap fitting 1 of the first example with respect to its basic construction and in particular its lever mechanism 20. This flap fitting 1 can also be inserted or integrated into a furniture panel, the side wall of the furniture body, for example according to Figure 6 Made from the flap fitting 1.

[0062] In these figures, the same reference numerals identify elements that are the same or have the same function as in the previous figures. Reference is explicitly made to the description of the first example. In particular, the differences between the two examples are explained in more detail below.

[0063] exist Figures 7a to 7c In the figure, the flap fitting 1 with the open housing 10 is shown in two isometric views ( Figure 7a , 7c ) and side view ( Figure 7b )illustrate. Figure 7a and 7b The flap fitting is shown in the closed position and Figure 7c The flap fitting is shown in the open position of its lever mechanism 20 .

[0064] The flap fitting 1 of the second example differs from the first example in the design of the spindle unit 42. As in the first example, the spring slot 41 is mounted on one side so that it can be displaced in a position in a fixed spring bearing 412 via the spindle unit 42 on the housing 10, and acts on an intermediate lever 43 at its other end via a free spring bearing 413.

[0065] The spindle unit 42 in the second exemplary embodiment differs in that the spindle (only Figure 7a 427) is arranged in a U-shaped guide rail 427. The spindle nut 426 is guided in this U-shaped guide rail 427. The pressure acting on the spindle unit 42 from the spring groove cavity 41 is absorbed not only by the spindle 421 in this design, but also specifically by the U-shaped guide rail 427. In addition, as shown in this example, a scale 428 can be optionally applied in the guide rail 427, wherein the position of the spindle nut 426 on the scale 428 is visible through the narrow slot in the guide rail 427. In this way, the presetting of the spindle unit 42 to a specific predetermined value can be performed. In addition, the scale 428 facilitates the same setting of multiple flap accessories 1 that guide the flap together.

[0066] Another difference in the second example relates to the design of the frame 12, in particular, the frame comprises reinforcing ribs 121 in the region of the rear portion of the flap fitting 1 opposite the opening. Furthermore, the damping unit 50 is integrated into the frame 12 in this example. The integrated construction of the damping unit 50 in the frame 12 simplifies the installation of the flap fitting 1, since the damping unit 50 does not have to be separately connected to the housing 10.
