Further preferred embodiments are the subject of the following description parts and / or the subclaims.

According to a preferred embodiment of the present invention, the receiving part is formed in the region of the first end of the slot. The area of the first end of the slot extends from the first end of the slot towards the second end of the slot less than 50% of the slot length, in particular less than 30% or less than 20% or less than 10% or less than 5%. The receiving portion in the longitudinal direction is preferred L2 of the slot at least in sections is part of the first end of the slot. This embodiment is advantageous because the locking of two components to each other only takes place when the components are arranged in an end position to each other. In addition, in such a case the further component introduced into the slot preferably lies on at least two surfaces, in particular on exactly three surfaces of the component forming the slot. By contacting, for example, three surfaces, an additional degree of freedom can be reduced, by means of which the components remain aligned with one another very precisely and in a defined manner. Preferably, the receiving part partially forms or delimits the first end of the slot.

According to a further preferred embodiment of the present invention, the slot forms at least one further receiving part or has at least or exactly one further receiving part. The receiving portion preferably adjoins the first flat surface F1 on or the absorption part interrupts the first surface F1 preferably in sections. The receiving part preferably forms opposite the first flat surface F1 a recess, the recess opposite the first flat surface F1 a depth T1 trained, preferably T1 <A1 applies. Alternatively, the further receiving portion is connected to the second flat surface F2 on or the further absorption part interrupts the second surface F2 in sections. The further receiving portion preferably forms in relation to the second flat surface F2 a recess, the recess opposite the second flat surface F2 a depth T1 trained, preferably T1 <A1 applies. This embodiment is advantageous because a defined clamping force can be set or predefined by the number of receiving parts and thus the number of clamping elements.

According to a further preferred embodiment of the present invention, the further receiving portion is formed in the region of the first end of the slot. According to yet another preferred embodiment of the present invention, the receiving portion and the further receiving portion lie opposite one another and preferably they overlap in sections or completely, in particular orthogonally to the longitudinal direction of the slot, they overlap at least partially and particularly preferably completely. The slot can thus be constructed symmetrically. This embodiment is advantageous since both clamping elements preferably only come into engagement or contact with the further component when the further component is preferably only less than the diameter of the clamping element or less than 70% of the diameter of the clamping element between contact with the clamping element and final or defined position or alignment or arrangement. In the final or defined position or alignment or arrangement, the further component is preferably in contact with two surfaces of the component which are parallel to one another and one which is inclined to the parallel surfaces, in particular an orthogonal surface.

According to a further preferred embodiment of the present invention, the clamping element has a material that is different from wood or consists thereof. The clamping element preferably has or consists of a polymer material. It is also possible for the clamping element to have a coating. Such a coating can preferably reduce wear and / or increase friction and / or create a material bond between the clamping element and the further component and / or between the clamping element and the receiving part or the respective receiving part. The clamping element preferably has greater elasticity than the material of the base body. This embodiment is advantageous because the clamping forces as a function of Properties of the clamping element or the clamping elements or the respective clamping elements are adjustable or predeterminable.

This embodiment is advantageous since the total weight of the clamping elements decreases with increasing size of the hole. This results in lower material consumption, recycling effort and transportation costs. Furthermore, the, in particular elastic, deformability of the clamping element can be set or predefined via the shape of the hole or its radius. The axial length of the clamping element differs from the height H1 less than 20%, especially less than 10% or less than 5% or less than 1%. The axial length of the clamping element is preferably less than or equal to the height H1 . This embodiment is advantageous because the clamping element preferably over the full height H1 interacts with the other component. Alternatively, however, it is also possible for the receiving part to be designed in several parts, in particular in two parts. The receiving portion then serves to receive several, in particular exactly two or at least two, clamping elements.

This embodiment is advantageous because the forces that occur can also be predetermined by this configuration.

The aforementioned task is also solved by an object. This object has at least one component, in particular wooden component, in accordance with one of the preceding components and a further component, in particular likewise with a plate-like base body. The further component is inserted into the slot of the component at least in sections while the clamping element is acted upon, the clamping element causing the further component to be locked in relation to the component. This solution is advantageous since simple or complex objects can be assembled, assembled or disassembled or dismantled quickly, easily and safely by joining several components according to the invention.

The piece of furniture is formed by several components clamped together according to one of claims 1 to 9. In a first configuration, these can be connected to one another as a chair or high seat. Furthermore, the components are in a second configuration as a bench or learning tower connectable with each other. This solution is advantageous since a piece of furniture is provided which can be converted from a first configuration into a second configuration in a few simple steps. As a result, the materials or components are used several times, which means that the furniture can be adapted to the changing needs of children, for example.
