Description

Modular furniture system

The present invention relates to a modular furniture system for various purposes, comprising at least one basic furniture module, which consists of a backrest element, a basic seat module, two upholstery elements and several foot elements.

STATE OF THE ART

From the prior art, modular furniture systems are known, which consist of several furniture units that can be detachably connected and fixed with one another.

A generic modular seating furniture is described, for example, in EP 3 292 793 A1. The seating consists of individual seating elements. The seating furniture elements can be connected to one another by connecting units, with several connecting recesses being provided on the underside in a grid-like manner in each seating furniture element. Each connecting unit has a foot element and connector pins, the foot element being arranged as the foot of the chair and the connector pins being arranged opposite the foot element in accordance with the connecting recesses of the seating furniture element. Thus, the seating furniture elements with the connector units can be connected to and detached from one another from below the seating furniture elements without tools and as desired in various ways. A seat part of the modular seating furniture shown in EP 3 292 793 A1 does not consist of two basic elements that can be connected to one another, but the seat part is designed in one piece so that the seating furniture cannot be shipped inexpensively in a package.

DE 24 02 525 A1 discloses a connection fitting for connecting several pieces of furniture to form a seating group. The fitting consists of a clamp arm and a bolt plate. The clamping arm is arranged in the plane of the underside of the furniture and has resiliently expandable latches Longitudinal slots. The bolt plate can be attached to an underside of another furniture element with two attachment holes. An engaging bolt is formed in the center of the bolt plate. By engaging the engaging bolt of the bolt plate between the notch longitudinal slots, the furniture elements can be firmly connected to one another from the underside. The clamp arm can be pivotably attached via a hole. The seating group does not have a multi-part seat part. Thus, a large volume of transportation is required and the transportation cost is expensive.

DE 86 07 261 U1 shows a set of components with which furniture elements can be detachably connected to one another on the underside by means of feet. The kit includes a pin connector and two sliders. Each slider is attached to a central axis of a frame or foot of the furniture element with a fastening pin. Grooves at both ends allow the connector to be placed in various positions in the slider and secured. DE 86 07 261 U1 shows one way of connecting two pieces of seating furniture to one another. A seat part of the chair is made in one piece and can only be shipped with a large transport volume. The transport costs are therefore high.

WO 2017/222580 A1 also discloses a modular furniture system that consists of several furniture units that can be connected with connecting elements. This is intended to facilitate transport and provide seating furniture that can be used flexibly. Since the external dimensions of rectangular and sloping furniture units are coordinated with one another, different seating groups can easily be put together. The coupling of the individual furniture units is supported by foot elements which are arranged on the underside of the furniture unit. The seating furniture to be connected is designed with a one-piece seat part, so that high transport costs are required during transport.

Furthermore, WO 2006/135509 A2 represents a modular furniture unit with which differently assembled seating groups can be created. This can make transport easier. The individual elements can be fixed to one another via a foot connection element become. The seating group does not include a multi-part existing seating part. This means that the seating furniture cannot be sent inexpensively in one package.

The disadvantage of the prior art is that the aforementioned modular furniture system requires a relatively large transport volume during transport, so that transport is complex and expensive.

Another disadvantage of the known modular furniture system is that the modularity can only be used within narrow limits.

Based on the above prior art, it is the object of the invention to provide a better means of transport and thus to significantly reduce costs.

It is a further object of the invention to create a modularity that can be freely combined, so that a wide variety of furniture landscapes can be implemented from identical basic furniture modules for different purposes.

This object is achieved by a modular furniture system with the features of claim 1. Advantageous further developments of the invention are the subject of the subclaims.

DISCLOSURE OF THE INVENTION

The invention relates to a modular furniture system for various purposes, comprising at least one basic furniture module, which consists of a backrest element, a basic seat module, two upholstery elements and several foot elements.

According to the invention it is proposed that the backrest element and the seat base module can be connected and fastened to one another without tools using the foot elements, so that the furniture base module can be placed in a shipping box with a small size, in particular with a size of up to 120 cm x 60 cm x 60 cm, and with a reduced weight, in particular with a weight of less than 30 kg, can be packaged together. Thus, a modular furniture system is proposed, which consists of at least one small, dismantled and thus easily transportable basic furniture module. The feature that the basic furniture module consists of a backrest element, a basic seat module, two upholstery elements and several foot elements, whereby these can be connected to one another by the foot elements without tools, enables a much smaller packaging volume compared to a conventional modular furniture system, so that the basic furniture module in a small Shipping box with a maximum size of 60 cm x 60 cm x 120 cm. In particular, a girth of up to 360 cm (the girth results from: (height + width) x 2 + length) can be adhered to. In addition, a total weight of less than 30 kg will be adhered to. With this package size and weight, parcels can be sent by a single parcel deliverer, whereby heavy-duty shipping can be dispensed with and shipping costs can be saved. For this purpose, the seat base module and / or the backrest element can preferably consist of a foamed material, for example of polypropylene or polystyrene, so that the furniture base module can have a low overall weight in relation to its volume. A tool-free assembly and disassembly of the furniture system and all individual parts such as cover, suspension, add-on parts is possible at any time.

This advantageously ensures that the modular furniture system can be shipped inexpensively in a shipping box with a shipping service provider, for example DHL, HERMES, UPS or the like, and can be easily transported by one person. The shipping costs for such shipping boxes are typically around 8 euros, while typical heavy-duty transport costs for complete furniture elements are up to 120 euros. In this way, the transport costs and the logistics effort involved in a shipment can be significantly reduced.

It is also advantageous that the modular furniture system can be assembled from at least one basic furniture module. As a result, different manifestations of the modular furniture system are possible as desired by assembling the basic furniture modules in different ways, so that the modular furniture system can be used in a living area, a Lounge area, a contract area or an outdoor area can be used.

In an advantageous development of the modular furniture system, the seat base module can consist of at least two seat base elements, the seat base elements preferably being of essentially identical design and being connectable to one another to form the seat base module using at least one, preferably functionally complementary, connecting means, preferably without tools.

In this development, the seat base element can be provided with an additional connecting means in an edge area. This ensures that the basic seat elements are securely and firmly connected to one another. Starting from the previous embodiment, in a further advantageous development the at least two pairs, in particular the multiple pairs of dovetail guides, can be formed in the wall area and / or in the floor area of the seat base element. In other words, the seat base element can be equipped with dovetail guides which are formed both in the wall area and in the floor area. This advantageously means that no additional space has to be provided on an outer surface of the seat base element for an arrangement of the dovetail guides.

In a further advantageous development, at least one pot-shaped foot element for supporting the basic furniture module on the floor side can be formed and preformed in the dovetail connections. Each dovetail joint can consist of a pair of two dovetail guides. Advantageously, at least one pot-shaped foot element can be formed in one piece on part of the dovetail connection. This makes it possible, in addition to the foot elements, through which the backrest element and the seat base element can be connected and fastened to one another without tools, to offer another option for supporting the basic furniture module, in particular for supporting the modular furniture system, and preventing the connection from being unintentionally loosened.

In a further advantageous development, on a bottom side of the seat base module and / or on a bottom side of the backrest element at least one, in particular a plurality of recesses can be provided for receiving the foot elements, the recesses preferably being formed in the edge region of the seat base module and / or the backrest element. The recesses can be pot-shaped. The foot elements can be inserted into the pot-shaped recesses, which are formed on the bottom side of the seat base module and / or the backrest element, preferably without tools. As a result, the seat base module can be connected to the backrest element or the seat base modules can be connected to one another as desired. A wide variety of furniture landscapes can thus be created for different purposes.

In a further advantageous development, adjacent, mutually arranged foot elements can be connected to one another by means of at least one bracket element. The bracket element can advantageously be designed in a U-shape. Advantageously, the U-shaped bracket element can also be designed to be insertable, the U-shaped bracket element having two ends

Can have insertion areas for inserting into foot elements of adjacent basic furniture modules and a connection area for connecting these foot elements. In this way, a connection between the two foot elements can be provided by means of the U-shaped bracket element. Here, the bracket element is preferably designed in one piece. Furthermore, the bracket element can consist, for example, of a metal, of wood or of a plastic.

Starting from the previous embodiment, the foot element can consist of at least two formwork parts that can be plugged together and latched together, with at least one formwork part having an embedding receptacle for an end region of the bracket element. More than one embedding receptacle can advantageously be provided so that end regions of two or more bracket elements can be received in order to enable corner connections or also cross connections by means of the bracket elements. The shell parts can preferably consist of a plastic. The end area of the bracket element can be inserted into the embedding receptacle. Everyone

Alternatively, the upholstery element can be pulled up after the basic furniture module has been assembled and fixed to the basic seat module and / or the backrest element by means of the Velcro strip. It is advantageous that a Velcro connection of the upholstery element with the seat base module or the backrest element by means of the Velcro strip provided on the bottom peripheral surface can be a U-shaped enclosure of the bottom edges of the seat base module or the backrest element under a force, so that the Prevents Velcro connection and a permanently reliable fastening of the upholstery element on the seat base module and / or the backrest element can be guaranteed.

In a further advantageous development, an insertion slot or insertion groove can be formed at least in sections, preferably circumferentially, on at least one edge on the bottom side of the seat base module and / or on the bottom side of the backrest element for inserting the upholstery element. In order to improve a plug-in connection of the upholstery element with the seat base module or the backrest element in a non-positive manner, the upholstery element can be provided at least in sections with an end strip in the insertion area. Based on the previous embodiment, at least one hem area of the upholstery element can be provided with an end strip to close the opening of the upholstery element, wherein the end strip can be inserted into the insertion slot so that the upholstery element can be attached to the seat base module and / or to the backrest element. The upholstery element can either be pulled onto the seat base module and / or onto the backrest element before the seat base module and the backrest element are joined, or it can be pulled up after the furniture base module has been put together. The upholstery element can then be attached by means of the end strip. The end strip can be designed as a plastic strip which can be inserted into the insertion slot and fixed so that the upholstery element can be prevented from being pulled down from the basic furniture module. In a fastening position, the plastic strip can be oriented vertically upwards, so that the hem area of the opening of the upholstery element is U-shaped may include lower edges of the seat base module or the backrest element. Through a plug-in connection of the upholstery element with the seat base module and / or the backrest element by means of the inserted end strip, the U-shaped enclosure of the bottom edges of the seat base module or the backrest element can be subjected to a force, so that the end strip prevents slipping out and a reliable fixation of the upholstery element can be reached on the seat base module or the backrest element.

In a further advantageous development, the seat base module and / or the backrest element can be trapezoidal, the backrest element being attachable to a long side or a short side of the seat base module by the foot elements. It is advantageous that the trapezoidal seat base modules and / or the trapezoidal backrest elements are connected to the seat base modules and / or the backrest elements, which have a different shape. An arbitrarily curved course of the modular furniture system with convex or concave course areas of the seating area can thus be made possible.
