DE2541074A1 - Readily collapsible shelving with easily interconnected uprights - uses common connecting pins with slit ends for engaging in aligned tapering blind holes - Google Patents

Abstract

The knock-down shelving comprises a system of vertical uprights (1) connected together by shelves (2) or transverse webs wherein the butt edges of the uprights are each provided with an inwardly tapering blind hole (4) so that a common connecting pin (3) can be inserted into two blind holes which are in alignment. The opposite ends of each connecting pin is provided with a cross-shaped slot (6) and the cross-sectional area of the pin corresponds to the cross-section of the opening to the blind hole. Thus, when inserting the pins into the tapering blind holes they fit tighter and tighter against the sides until they are resiliently clamped, with the ends of the pins being compressed on account of the slots (6).

Description

The invention relates to a collapsible shelf made of vertical post elements and connecting them Shelves, cross struts or the like.

With the previously usual dismantlable shelves or add-on shelves, in which the posts are made up of several butting post elements can be assembled and at the joints shelf or other transverse stiffening elements can be switched between, screw bolts and with these adjustable clamping bodies are used, which are braced against each other will. Such a system is difficult to use

and expensive in terms of the production of the necessary Individual parts.

The object of the invention is to create a collapsible shelf that is easy to clamp without Threaded or other clamping connections can be built up and dismantled. ■

This object is achieved in that the post elements at their joints each with an inward tapering blind holes are provided and a common connecting pin can be inserted into aligned blind holes which is connected to its opposite ends each with a Phillips head is provided and whose cross section corresponds to the entry cross section of the blind hole. When inserting the pins into the tapering blind holes, the pins increasingly adapt to the Sacklochtjuschnitt by compressing the pin ends so that the pins clamp elastically in the holes. Such a system is particularly suitable for shelves Wood or wood-like materials. The elastic mutual tension can be increased by the fact that during the training made of wood the connecting pins have a larger equipment. degree of dryness than the post elements, so that they are after the assembly swell with absorption of moisture from the post elements.

The length of the pins depends on whether

609839/0272

Lich post elements are to be butted or shelves or other cross struts are to be interposed.

The most suitable cross-section for the connecting pins and these receiving holes is the circular cross-section.

The invention is illustrated in the following with the aid of a schematic Drawings explained in more detail.

Fig. 1 shows a vertical section through a

inventive collapsible shelf with butt-ended shelf, wherein the post elements form an end post or corner post;

FIG. 2 shows a cross-section corresponding to FIG. 1 with a butted shelf, the post members forming a center post;

Fig. 3 shows a cross section through a connecting element according to section III-III in Fig. 1v

A shelf according to the invention consists essentially of three basic elements, namely post elements 1, shelf bases 2 and connecting pins 3. The post elements 1 have at their butt ends for receiving the connecting pins

3 a blind hole 4 that tapers inward. The shelves 2 to be accommodated between the post elements have corresponding through holes 5 in the area of aligned holes of the post elements to be combined, the diameter of which corresponds to the largest cross section of the connecting pins 3, which are provided at their ends with axially extending cross slots 6, the length of which is less than the depth of the blind hole. The cross section de? öti-ffee enfcfSptfiGhfc ürnn inlet cross-section of a blind hole. If post elements are butt jointed, the pin length corresponds to the depth of two Saak holes. If, according to FIGS. 1 and 2, a shelf 2 is also to be clamped, the length of the pin is longer by its thickness. If a pin hole is inserted into a blind hole, the inserted end adapts to the blind hole because of the cross slots and ensures good tensioning with elastic deformation.

When assembling, one usually proceeds from the bottom up by setting up a set of post elements, insert the pins 3, put a shelf on the pins and put the next set of posts on top, etc. Should a shelf are pushed, you can run the shelf joint as an overlapped joint as shown in FIG. 2, so that the cultivation further shelf fields is possible.

Instead of shelves, others can also be used for cross stiffening, e.g. a pair of cross braces clamped in place will.

It is of particular advantage if the pins have a higher degree of drying when a shelf is made of wood than the post elements, there will then be some swelling of the pins due to the absorption of moisture from the post elements and thus an even greater tension of the parts takes place.

The connecting pins and the holes cooperating with them preferably have a circular cross-section, such as it is shown. A square cross-section is also well suited. .

With regard to the sheer tensioning of the individual parts, such shelves are easy to assemble and also to be dismantled again, so that the elements lend themselves to a quick-build system, with the individual parts being extraordinary can have a simple design.
