Description

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 seat basic module, two upholstery elements and several foot elements.

STATE OF THE ART

Modular furniture systems, which consist of several furniture units that can be detachably connected and fixed to one another, are known from the prior art.

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

The DE 24 02 525 A1 discloses a connecting fitting for connecting several pieces of seating 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 longitudinal catch slots that can be expanded in a resilient manner. The bolt plate can be attached to the underside of another furniture element using two mounting holes. An engagement bolt is formed in the center of the bolt plate. By snapping the engagement bolt of the bolt plate between the longitudinal slots, the furniture elements can be firmly connected to one another from the undersides. The clamping arm can be pivoted via a hole. The seating group does not have a multi-part seat part. A large transport volume is therefore required and the transport costs are expensive.

In the DE 86 07 261 U1 A set of components is shown with which furniture elements can be releasably connected to one another on the underside using feet. The component set includes a pin-shaped 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 moved into different positions in the sliders and secured. In the DE 86 07 261 U1 shows a way to connect two pieces of seating furniture together. A seat part of the seating furniture is made in one piece and can only be shipped with a large transport volume. The transport costs are therefore high.

The WO 2017/222580 A1 further discloses a modular furniture system that consists of several furniture units that can be connected with connecting elements. This is intended to make transport easier and provide flexible seating. Since the external dimensions of rectangular and slanted furniture units are coordinated, different seating groups can be easily put together. The coupling of the individual furniture units is supported by foot elements that 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, the WO 2006/135509 A2 a modular furniture unit with which differently assembled seating groups can be created. This can make transport easier. The individual elements can be fixed together using a foot connecting element become. The seating group does not include any existing multi-part seating part. This means that the seating cannot be sent inexpensively in one package. Another example is out US7547073B2 known.

A disadvantage of the prior art is that an 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, the object of the invention is to provide a better transport option and thus significantly reduce costs.

It is also an object of the invention to create freely combinable modularity, so that a wide variety of furniture landscapes for different purposes can be realized from identical basic furniture modules. This task is solved by a modular furniture system with the features of claim 1. Advantageous developments of the invention are the subject of the subclaims.

DISCLOSURE OF INVENTION
