ABSTRACT:
TECHNICAL FIELD
The invention relates to a component group consisting of a plurality of parts which can be fitted together, in which each of the sides, which are to be connected to one another, of the parts has at least one undercut groove and a web, and in which the shape and position of the grooves and webs which can be brought into engagement with one another are coordinated with one another in such a manner that by means of an imaginary 180° pivoting in each case of one of two respectively adjacent parts about an axis placed between the parts and running parallel to the grooves and webs, the grooves and webs of the parts can be transferred into a congruent position.
PRIOR ART
FR 21 74 320 A discloses a component group which consists of two identical components, has plug-in connections and whose parts have grooves and webs on opposite sides. The parts used in the known component group are not suitable for forming component groups which consist of at least one intermediate part and two identical end parts which are provided with connecting elements on just one side.
Also, “Navy Technical Disclosure Bulletin vol. 1, No. 1, May 1976, p. 15” discloses an oil block having plug-in connections which have grooves and webs but which are not suitable for producing a stand, since their connecting points are of hinged design.
SUMMARY OF THE INVENTION
The invention is based on the object of providing a component group of the generic type, which is under consideration and consists of a plurality of parts, in which identical end parts are joined to an intermediate part or to a plurality of likewise identical intermediate parts. According to the invention, this object is achieved in that the component group forms a stand which consists of two end parts and at least one intermediate part arranged between said end parts, and in that the . . . with at least one groove and at least one web on just one side arranged between said end parts, and in that the end parts, which are provided with at least one groove and at least one web on just one side, are designed such that they can be interchanged.
Further details and features of the invention are revealed in the subclaims and in the following description of a plurality of embodiments illustrated in the attached drawing.
