DE19917995A1 - Connecting system for various furniture components, with horizontal elements, vertical elements and special screws with sleeves and locknuts - Google Patents

Abstract

The connecting system enables horizontal components such as board (1) to be connected to vertical columnar component (14) with the aid of special screws/ The screws can be prefabricated as a complete body or can consist of individual parts assembled to each other, such as threaded rods (8), sleeves (5) and locknuts (7).

Description

The invention relates to a system of connecting various Elements, always with the same type using special screws different lengths (depending on column length).

Connection systems for assembling elements are known.

There is a wide range of such systems and they are used in different areas such as B. in furniture manufacturing.

All of these systems show u. Disadvantages. Of the disadvantages To be mentioned: Limited fields of application, limited morphological or synthetic possibilities, difficult assembly, solid problems.

Thus, it would be desirable to invent a system that does the above Avoids disadvantages if possible.

This becomes quite satisfactory with the invention described here reached.

The system described here enables the very firm and easy to manufacture connection of different elements, such as. B. horizontally placed plates u. Shelves 10 , 11 , 12 , with vertically positioned supporting columns of various cross-sections and dimensions 14 . These parts are provided with holes (the plates) and grooves (the columns) so that they can be connected with the special screws.

These special screws consist of

• a) the threaded rods 8 (the lengths are adapted to the lengths of the columns 14 ),
• b) the sleeves (which can be of different types 6 and which are constructed in such a way that they can be screwed together with a key (corresponding to the type of sleeve) and
• c) the nuts 7 .
  The threaded rods are screwed into the sleeves, while the counter screw nuts serve to secure the entire screw.
• d) These special screws can also be used as a finished body be made: screws of different lengths and sleeve-like head (with internal thread).

The horizontal elements (z. B. plates and shelves 10 , 11 & 12 ) are provided at the desired locations with holes, the diameter of which is corresponding to the diameter of the threaded rods. The columns have a cross-section corresponding to their length (axial) grooves, like the threaded rods and holes at the two outputs of the grooves, the diameter of which u. Depths allow the heads of the special screws to be completely immersed in them 14 , 14.1 .

You can provide the columns and the plates with additional grooves 14 in which walls 13 are placed so that you can assemble boxes.

The columns can have any cross-section, e.g. B. square, polygonal or round without losing its strength.

The assembly takes place in the following way:
You take the bottom piece 15 (let's just say the foot), in which a sleeve is already screwed into the lower side.

The plate 10 is placed on this first element so that its hole comes on the hole of the foot and is fastened with the special screw. Of course, its sleeve now protrudes from the plate. Next, a column is placed on this sleeve, which completely covers the previous sleeve and fastened to the plate with the next special screw of the appropriate length. This process is continued arbitrarily.

You can make sure that there is no sleeve on the top end plate cover with a lid (shaped as desired).

The advantages of this system

You have great freedom in the selection of shapes and. Sizes of horizontal as well as vertical elements, which gives great freedom in the Design means.

It is very easy to provide walls with which boxes are created can. You can easily do so in the appropriate manner Grooves of the columns are pushed in.

Assembling and disassembling will be easy for everyone because no special knowledge and no special skill is required to to carry out the same process again and again, namely the fastening one piece to another using the same type of screw. As an aid, one would only need the appropriate one Key.

The type of attachment is very strong because in a sense the whole thing is like for example, the reinforced concrete behaves: the column absorbs the compressive forces, while the screws absorb the tensile forces.

The type of connection is imperceptible after the installation of the Piece of furniture, since the groove with the screw simply faces backwards becomes.

Finally, it should be mentioned that manufacturing, storage and Packaging is easy, since it is a question of individual repeated elements.  

Legend

Claims (1)

It is a system of connecting different elements, with special screws always of the same type but of different lengths (depending on the column length).
The main elements of the system are:

• 1. The horizontal elements (plates, shelves, etc.), which are intended to be used in a horizontal position and, depending on the desired target, have one or more holes, the diameter of which corresponds to the diameter of the special screws.
• 2. The vertical, load-bearing elements (columns), whose cross-section, dimensions and shape can vary, depending on the desired end goal. These columns have a groove for the threaded rod u. possibly additional grooves for attaching walls. The pillars have a hole at each end in which the head (sleeve) of the special screw disappears.
• 3. Special screws of different lengths consisting of
  • 1. the threaded rods (the lengths are adapted to the lengths of the columns),
  • 2. the sleeves, which can be screwed with an appropriate key, and
  • 3. the lock nuts.

The threaded rod is screwed into the sleeve, while the lock nut serves to secure the entire screw.
These special screws can also be manufactured as a finished body: screws with different lengths and socket-like head with internal thread.
