Description

The present invention relates to a dismountable upholstered furniture with a modular structure, according to the preamble of claim 1.

As a rule, upholstered furniture is large, bulky and unwieldy. Transport always requires several people. The feet of many upholstered furniture can be unscrewed for transport, but handling through narrow stairwells is often a problem.

In other models, parts of the sofa can be assembled; this separation option is limited to the arm sections and back. The seat, back and arm parts are always made in one piece.

An example of a piece of furniture that can be dismantled is shown in the DE 20 2004 008 408 U1 described. This seating furniture includes a seat, a backrest, 2 armrests and a number of fasteners to connect them together.

Another example of a seat that can be dismantled is shown in US 9,277,813 B2 described dismountable seating furniture in which the seat, back and armrests are provided with magnets so that they can be connected to each other.

The DE 20 2009 007 814 U1 describes a dismountable sofa which consists of a seat, a back and a pair of armrests, which are connected to each other by plug-in fittings.

This in DE 200 00 513 U1 The example of a dismantled seating furniture described describes a base body with receptacles for inserting support parts such as side and backrests.

In the DE 9 311 433 U1 is a dismountable seating furniture that consists of upholstered seat elements that consist of a dismountable frame, the side parts of which are connected to one another by means of plug connectors and into which a back can be inserted.

All known furniture of this type consists of a number of different elements, with the seating unit in particular being made in one piece, which makes it very unwieldy.

The in FR 2 244 334 A5 The dismountable seating furniture described consists of individual upholstered parts which are connected to one another by a circumferential wire bracket, which affects the seating area.

This in US 2008 / 0 284 228 A1 The example described shows a dismountable seating furniture made of a base frame which consists of a large number of flat elements that are put together crosswise and which form upward formations into which the upholstered parts can be inserted.

This requires one or more holders in the middle of each upholstered part, as well as the corresponding shapes on the base frame.

Changing living conditions require significantly more flexibility today. Large, bulky furniture in particular should offer the possibility of being disassembled to save space for transport or storage purposes. The increasing mail order business also requires furniture that can be dismantled.

If furniture can already be dismantled, you should also offer the possibility of rearranging it to suit different needs if spatial conditions have changed.

Another requirement for such furniture are requirements regarding logistics and storage. The desired flexibility should therefore be achieved with as few different components as possible.

The invention is based on the object of creating a dismantled piece of seating furniture that meets all requirements and in particular can be dismantled into individual components that are as handy as possible, which can be transported by one person and consist of individual elements of little different design and still offer maximum flexibility .

This task is achieved by upholstered furniture with a modular structure according to the features of claim 1. Advantageous designs of the upholstered furniture result from the dependent claims.

The upholstered furniture according to the invention, which is suitable for disassembly, is based on a new structure and comprises at least three individual, essentially cuboid-shaped upholstery elements arranged parallel one behind the other and transversely to the seating direction with the width of at least one seat unit, which can be connected directly or indirectly by means of a detachable connection Connecting element or support system are connected to each other and the top sides of which together form the seat of a seat unit.

Where in a Cartesian xyz coordinate system the seat depth is defined in the y-direction, the seat width in the x-direction and the seat height in the z-direction and a plane spanned in the xy direction depicts the position of the seat.

The upholstery elements that form a seat unit are the same in their basic shape and have corresponding lateral outer surfaces that run perpendicular to the floor surface. The undersides of the upholstery elements lie in a horizontal plane parallel to the floor surface.

By putting together the same upholstery elements one behind the other, each of which forms a partial seating surface on the top, it is possible to create seating furniture with seats of different seat depths or to change them if necessary.

The width of the upholstery elements specifies a grid for the structure in which the upholstery elements can then be arranged at least within a seat unit. The length of the upholstery elements corresponds to the seat width of a seat unit. In an advantageous embodiment, the length simultaneously corresponds to two, three, four or five times its width.

One embodiment variant provides that to form a backrest, a higher upholstery element is added in the y direction, which clearly projects beyond the seat and then forms a backrest in the direction of the seat. Such a higher upholstery element is also used to form an armrest, which is then pivoted through 90° with the lateral outer surface of an adjacent seat unit, connected by means of appropriate connecting elements and forms an armrest.

If the width and length of all upholstery elements are subject to a common grid as described above and the length corresponds to two, three, four or five times the width, various individual seating solutions can be designed from just 2 types of upholstery element that differ in height, with the lower one being for the seats and the higher version for backrests and armrests are used.

Furthermore, it is provided that the lateral outer surfaces of all upholstery elements are aligned perpendicular to the floor surface at least below the seat surface and their height in the z-direction corresponds at least to their width in the y-direction.

It is also provided that the individual upholstery elements, which together form a seat unit, are connected by means of connecting elements in such a way that neighboring upholstery elements partially rest against one another, but an insertion groove is formed between them, into which an insertion part of an insertion element which is located above the seat as a backrest , armrest or table, can be inserted.

In this way, backrests, armrests and/or tables can be inserted into the insertion grooves of the seat at any point, and their position can also be changed if necessary by simply repositioning them, for example to change the seat depth.

To insert the insert parts into the insert grooves, it is advantageously provided that at least the upper edges of the cushion elements are rounded in the x direction to a radius of at least 10 mm.

The structure of the cushioning elements provides that there is preferably a support frame inside, which is also partially designed as a base plate, over which the cushioning structure is to be positioned, which in turn is covered by a cover, the cover being designed to be removable.

The cuboid basic shape of the upholstery elements with side surfaces running parallel to one another without undercuts advantageously offers the possibility of designing a replaceable upholstery cover in such a way that all closure elements can be positioned invisibly on the underside of the upholstery elements.

It is envisaged that a maximum of variability in terms of redesign in the event of a change in use is achieved through the grid structure with, if possible, always the same handy cushioning elements or only two different cushioning elements with different heights.

The grid structure also makes it possible to replace or insert elements of the same structure anywhere at any time that have different shapes or features above the seat; a high-back back or a version with a headrest or other functions is also being considered.

It is also planned to use cushioning elements with different cushioning hardness arranged within a seat. By changing the arrangement, the seating comfort within the seat can be influenced.

Depending on the design of the connecting elements and taking into account the possible fastening points, upholstery elements that differ in width from the grid structure or that are double or can also be used within a seat unit correspond to three times the grid.

The connection of the upholstered elements is carried out using a support system, which is part of the upholstered furniture. The support system can be designed as a base frame with feet or base and consists of basic profile elements, which are each positioned laterally under the upholstery elements of a seat unit in the y direction, with the fastening points being on the underside of the upholstery elements.

These basic profile elements comprise at least one horizontal flange part, which has two rows of fastening points aligned parallel to one another, which can be connected to the aligned rows of fastening points on the underside of the cushion elements which run parallel to the outer edges of the cushion element. The distance between the two rows of fastening points on the flange part corresponds to twice the distance between the fastening points on the support frame of the upholstery elements and the outer edges of the upholstery element lying to the side of the seat.

For versions standing on the floor, the upholstery elements can also be connected directly using connecting elements in the form of tabs, brackets or screw connections.

In versions in which all the padding elements used have the same grid width, the distances between the individual fastening points on the flange parts within a row also correspond to the distance between the two rows, which then corresponds to half the width of the padding elements.

The fastening points on the underside of the support frame of the cushioning elements are arranged in such a way that there is one fastening point in each corner at a distance of a quarter of the width of the cushioning element from the nearest outer edges of the cushioning element.

Further fastening points on the underside of the support frame are located from the fastening points in the corner by the distance between the two rows of fastening points on the flange part, parallel to the outer edge of the upholstery element in alignment with the next corner fastening point. Unless there is already an attachment point in the corner at this point.

Due to the position and arrangement of these corresponding fastening points on the flange part of the basic profile elements and the support frame of the upholstery elements according to this grid, it is provided that a basic profile element is located in the middle under two seat units located next to one another, each of which consists of upholstery elements which form a seat surface or seat and backrest with these in a force-fitting manner can be connected, or alternatively the basic profile element can be secured completely under a seat unit, laterally indented by the distance between the rows of fastening points on the flange part. It is envisaged that through the arrangement of the fastening points in both versions, each upholstery element with each basic profile element assigned to this seat unit can be fixed at at least 2 fastening points, the length of the basic profile elements specifying the possible number of connectable upholstery elements within a seat unit in the y-direction.

It is envisaged that the upholstery elements on the side of the seat, which serve as armrests, are also fastened by means of the base profile element, which, as in the positioning for two seat units, is mounted laterally offset only half under the seat unit in question. Since only fastening points along a row are available on the base profile for fastening an armrest upholstery element, it is intended to additionally fix the relevant upholstery element at at least one further point.

This is preferably done by means of a hanging part, which runs between two upholstery elements of the seat unit and is fixed to the horizontal flange part underneath, as well as to the side of the seat on the base profile element, whereby it then offers a fixing option positioned above the base profile for hanging the armrest upholstery element on the side of the seat unit , which is then additionally fixed to the intended fastening points of the basic profile element.

It is thus provided that the hanging part has a hook part for fixing it to the base profile element, with which it can be hooked onto the side of the flange part, as well as a fixing edge which is fixed in a groove located at the top of the flange part.

The connection between basic profile elements and upholstery elements takes place through a non-positive connection. Preferably by means of a screw or plug and screw connection.

The basic profile element described as a support system has, in an advantageous embodiment, a profile portion below the flange part which extends downwards and has at least one undercut longitudinal groove into which it can be moved Fixing mounts can be inserted to attach feet or gliders underneath.

Furthermore, it is intended to introduce foot elements of a different type into openings at the head ends of the downwardly extending profile portion. Another type of design of the basic profile element provides that the downwardly extending profile portion is designed directly as a foot in the form of a runner of a bracket or a cheek.

In the previously described embodiment, the basic profile element is to be manufactured from an extruded profile.

Another type of design of the connecting elements for upholstery elements standing directly on the floor provides that a bracket element can be inserted into one fastening point in the form of a slot on the underside of two adjacently positioned upholstery elements and thus connects both upholstery elements in such a way that they are against one another Slipping or tilting relative to each other are secured, and here too, if necessary, an additional non-positive fixation of the bracket elements can be introduced.

The attachment points for the bracket elements on the underside of the cushion elements are at least the same distance from the lower edge of the cushion element closest to them.

The upholstered furniture like you see in the 1 until 9 are shown, show various possible combinations and exemplary embodiments of how the same upholstery elements 3a-3f and 4a, 4b, which only differ in their height, can be arranged to form different seating furniture or different seating units 1.

In a Cartesian x-y-z coordinate system, the upholstery elements are arranged in such a way that the seat depth is defined in the y-direction, the seat width in the x-direction and the seat height in the z-direction and a plane spanned in the x-y direction indicates the position of the seat 2 above a floor surface .

A seat unit 1 is defined as an upholstered piece of furniture that consists of at least three individual, essentially cuboid-shaped upholstery elements 3a, 3b, 3c that are arranged parallel to one another and transverse to the y-direction and detachably connected to one another.

1 shows a seat unit 1 consisting of three upholstery elements 3a, 3b, 3c, the top sides of which together form a seat surface 2 and a common lateral outer surface 5a aligned perpendicular to the floor surface. The length and the upholstery elements correspond to the seat width, which is between 44 cm and 100 cm with a dimensional deviation of no more than 5%. At least two of the cushioning elements 3a, 3b, 3c no longer differ by 10% in height and two in width.

The width of the cushioning elements 3, 4 in the y direction is at least 14 cm and at most 34 cm, the width corresponding at least to their height in the z direction.

The width of the upholstery elements specifies a grid which extends at least partially in the y-direction of a seat unit 1.

The seat depth of the seat surface 2 of a seat unit 1, which extends in the y direction and is formed from at least 3 upholstery elements 3a, 3b, 3c, is at least 42 cm and at most 102 cm,

If the length of the cushion elements 3,4 corresponds to the seat width and at the same time the depth in the y direction of a seat unit 1, the raised cushion elements 4a to form a back cushion and cushion element 4b to form an armrest have the same dimensions.

The width and length of all cushion elements 3,4 are subject to the same grid, so the length corresponds to two, three, four or five times the width of a cushion element. Thanks to this structure, all upholstered elements 3,4 can be used to create different upholstered furniture 1-10 arrange.

The upholstery elements 3a, 3b, 3c of a seat unit 1 are the same in their basic shape and have corresponding outer surfaces 5 directed towards one another at least below the seat surface, which are aligned perpendicular to the floor surface. By adding further identical upholstery elements 3d, 3e, 3f in the y direction, the seat depth is as in 3 and 4 shown can be expanded as desired.

By adding a higher backrest padding element 4a to the upholstery elements 3a, 3b, 3c in the y direction, which protrudes beyond the seat 2 by at least 12cm, in the y direction above the seat 2 as in 2 shown a backrest 7 formed.

If a higher backrest cushion element 4a is used as in 5 and 6 shown, arranged in the y-direction between upholstery elements 3a-3f, 2 backrests 7 are simultaneously formed in the y-direction on both sides towards the seat surfaces 2.

The 4 and 6-9 show that an armrest 8 is formed by adding a higher armrest padding element 4b, which protrudes above the seat surface 2 by at least 12 cm, to the common lateral outer surface 5a running in the y direction of padding elements 3a, 3b, 3c 4a of a seat unit 1 .

7 shows an embodiment referred to as an armchair, wherein a seat unit 1 formed from three upholstery elements 3a, 3b, 3c forms a seat surface 2, to which three higher upholstery elements have been added, of which a backrest upholstery element 4a arranged in the y direction, a backrest 7 and two Armrest padding elements 4b, each arranged on the side of the seat 1, form an armrest 8.

In the 8th The embodiment shown represents a sofa that has two seat units 1 consisting of three cushioning elements 3a, 3b, 3c, each of which forms a seat 2 and which has been expanded to include four higher cushioning elements, of which two backrest cushioning elements 4a are arranged in the y direction a backrest 7 and two armrest padding elements 4b each form an armrest 8 on the side of the two seat surfaces 2.

In 10 is shown using the example of two seat units 1 that by arranging upholstery elements between the mutually facing outer surfaces 5 of upholstery elements 3a, 3b, 3c, 3d positioned one behind the other in the y-direction, at least one insertion groove 9 is formed in the x-direction, into which different types are formed Allow attachment elements in the form of back elements 11, table elements 12 or armrest elements 13 to be inserted. The illustration shows two back elements 11, each of which forms a backrest surface 7, one of which is inserted into the seat surface 2. Furthermore, each is
a table element 12 and an armrest element 13 which forms an armrest 8 can be seen, the armrest element 13 being half inserted into the seat 2. All upper edges 6b of the cushioning elements 3a, 3b, 3c, 3d in the x direction are rounded to a radius of at least 10mm and at most 40mm to make it easier to insert the plug-in parts.

In order to achieve maximum flexibility, the fastening points 24 of the cushion elements 3, 4 are arranged on the underside 16 of the support frame 17, with the connecting elements extending at least partially under the cushion elements.

The connecting elements are designed either in the form of a base frame, which forms a connection with several cushioning elements assigned to it, or in the form of a direct connection, which forms at least one connection directly between two adjacent cushioning elements 3,4.

The connecting elements each engage non-positively in the support frames 17 of the cushioning elements 3,4.

One in 11-15 shown embodiment of a support system according to the invention, which serves as a base and connects the upholstery elements, provides that a base profile element 21 is positioned laterally under a seat unit 1 in the y direction, which has fastening points 23, 24 on the flange parts 22 and on the underside 16 of the Upholstery elements 3a-3c, and or 4a, 4b can be connected to these.

A basic profile element 21 comprises at least one horizontal flange part 22 with 2 rows of fastening points 23a, 23b aligned parallel to one another, the distance from one another corresponding to the distance between the parallel rows of fastening points 24a, 24b on the underside 16 of the upholstery elements 3a-3c, 4a on the side of a seat unit 1 , whereby the distance between the parallel rows of fastening points 23a, 23b on the flange part 22 corresponds to twice the distance from fastening points on the support frame 17 to the outer edge 6a of the upholstery element lying on the side of the seat surface.

If upholstery elements 3a-3c, 4a within a seat unit 1 have the same width, or a width that is subject to this grid, the distances between the individual fastening points 23 on the flange parts 22 within a row also correspond to the distance between the rows 23a, 23b from one another, which then corresponds to half the width of the cushion elements 3a-3c, 4a.

In the 12 The arrangement shown of cushioning elements 3a, 3b, 14 to form a seat unit 1 which contains a cushioning element 14 of double width shows that cushioning elements can also be integrated into the base profile element 21 of the support system, provided, as shown, the distances between the fastening points 24 are subject to the same grid as for upholstery elements of a single width.

13 partially shows the structure of the cushioning elements 3a, 3b, 3c, 4a and 4b, which each consist of a support frame 17 in or on the underside 16 of which there are fastening elements 24 and a cushioning material 18 arranged above it, which is then made up of a cover together with the support frame 17 19 is covered.

In 14 is shown how the same basic profile element 21 is used as a connecting element at a wide variety of positions with the aid of the corresponding rows of fastening points 23a, 23b and 24a, 24b between the flange parts 22 of the basic profile elements 21 and the individual cushioning elements 3a, 3b, 3c, 4a and 4b .

The basic profile element 21 can be positioned either between two seat elements 1a, 1b, between seat element 1a and an armrest cushion element 4b which forms an armrest 8, or laterally indented under a seat element 1b, whereby there are at least two in each position with the respective associated cushion element Fastening points 23, 24 correspond and can be non-positively connected by means of fixing elements. The length of the basic profile elements 21 through their attachment points 23 specifies the number of mountable upholstery elements in the y direction.

Upholstery elements 3,4 whose width corresponds to the grid in the y direction each have four fastening points 24 at both ends of their underside 16 in the x direction, which are arranged squarely at a distance of half the width of the upholstery element from one another, with their distance from the on The closest padding element outer edge corresponds to a quarter of the padding element width.

The design of the basic profile elements 21 provides that this has at least one profile portion 32 below the flange part 22, which extends downwards and has at least one undercut longitudinal groove 33.

The undercut longitudinal groove 33 on the base profile element must be designed so that it is as shown in 12 shown, can accommodate at least one displaceable fixing receptacle 36 for fastening a foot element 34b.

The downward-facing profile portion 32 of the basic profile element 21 points as in 11 As can be seen, there are cavities at both ends, which offer the possibility of inserting a foot part 34a, which has a corresponding plug-in receptacle 35, and, if necessary, fixing it with appropriate screw connections.

In order to attach an armrest padding element 4b, which forms an armrest 8, to the common lateral outer surface 5a of a seat unit 1, it is necessary to additionally fix this armrest padding element at a point which is located above the flange part 22 of the base profile element 21. This fixation is achieved in that at least one hanging part 26, which runs between two upholstery elements 3a-3c, 4a of the seat unit and is fixed to the horizontal flange part 22 underneath and, with its tab part 27 on the side of the seat, has an upper fixing point 31 for the armrest. Upholstery element 4b offers. The hanging part 26 has at least one hook part 28 and a fixing edge 29 for fixation on the flange part, which is fixed in a groove 30 located at the top of the flange part 22. This is in 15 and 15a clarified.

One of the connection options for the upholstery elements is in 16 shown. On the underside 16, the cushioning elements 3a, 3b are equipped with fastening points 24 in the form of slots, which serve as a receptacle for a bracket element 37 inserted from below, whereby two adjacent cushioning elements 3a, 3b can be connected to one another. One side of one of the two bracket elements 37 is already inserted into an attachment point 24 on the cushion element 3a.

The arrangement and spacing of these fastening points 24 is designed so that almost any combination of cushioning elements 3, 4 can be produced with the same bracket elements 37. So shows 17 an upholstered piece of furniture that consists of interconnected upholstery elements 3, 4 which form a seat 2, as well as those which form a backrest 7 or an armrest 8.
