2 Claims, 8 Drawing Figures PAIENTEUSEPI 11924 3.8235794 saw 10!? ARRANGEMENT FOR DETACHABLY INTERCONNECTING ELEMENTS An object of the present invention is to provide an arrangement for detachably interconnecting elements which is suitable for furniture.
The present invention consists in a shelf securing arrangement such as may be used in a bookcase comprising in combination:
i. a shelf provided with a recessed portion,
ii. a retainer fitting overlapping the recess and being provided with an elongated opening allowing access to the recess and forming a lipping portion of the retainer fitting,
iii. a step member for supporting the shelf,
iv. the step member being provided with a hooking portion which when introduced into the recess through the elongated opening of the retainer fitting extends upwards of the lower surface of the shelf and is engageable with the lipping portion of the retainer fitting,
v. bores for dowels extending between the shelf and step member,
whereby the shelf is secured to the step member by insertion of the hooking portion into the recess of the retaining fitting through the elongate holes, and then the shelf is turned relative to the step member through approximately a right angle to engage the hooking portion with the lipped portion, and fitting a dowel between the shelf and step to lock the parts together.
The invention is explained in the attached drawings, wherein:
FIG. 1 shows a fitting forming part of an arrangement according to the invention over a recess in one fumiture element;
FIG. 2 shows a section along the line IIlI in FIG. I placed over the recess;
FIG. 3 shows a corresponding section along the line III-III in FIG. 1.
FIG. 4 shows an end of a secondfurniture-element forming part of the arrangement according to the invention with a tongue adapted to engage the fitting according to FIG. I seen from the side;
FIG. 5 shows the same end as FIG. 4, but seen from above;
FIG. 6 shows the same end as FIG. 4, but seen in the direction of the arrow in FIG. 4;
FIG. 7 shows the arrangement according to FIGS. 4 6 mounted with the tongue fitted into the fitting shown in FIGS. 1 3 and one step substantially parallel to a shelf;
FIG. 8 shows the arrangement of FIG. 7 after the step has been rotated to stand at right angles to the shelf.
There are provided at least two fittings 1, each having an opening 2, and secured in such a way, for instance, by means of screws 3, over the recesses 4 on the underside of, for example, a shelf 5 in a set of shelves that each recess 4 extends from the opening 2 in the longitudinal direction of the shelf.
Two hooks 6 are provided at the ends of projections 7 projecting from the top ends of, for instance, steps 8 in a bookcase. The books 6 are dimensioned to fit the corresponding opening 2 when the upright of this step 8 is placed parallel to the underside of the shelf 5, and to engage the edge of the openings 2 and stick into the underlying part of the recess 4 when the upright step 8 is slewed out to stand at right angles to the underside of the shelf 5. The part of each hook 6 that can be inserted through the opening 2 has an outline formed approximately as a semi-circle whose radius is substantially equal to the length of the opening 2 and in the longitudinal direction of the shelf 5.
The upright step 8 is provided with two bores 9, so arranged that when the upright step 8 is at right angles to the shelf 5 and the hooks 6 have engaged the edges of the openings 2 they shall be in coaxial coincidence with the through bores 10 in the shelf 5. Pins 11 are adapted to fit the bores 9, 10 and, if required, bores (not shown) in an upright step located over the shelf 5, so that the upright step 8 is prevented from turning about the hooks 6.
Although only one form of embodiment has been shown and described above, other forms are possible within the scope of the invention.
We claim:
1. A shelf securing arrangement for use in a book case comprising in combination:
