Abstract

In a piece of furniture, such as a piece of seating or rest furniture of the type comprising a substantially rectangular frame having two opposing frame sidepieces, a plurality of parallel, longitudinally extending grooves is provided on opposing surfaces of said sidepieces. A first flange extending in the longitudinal direction of the profiled rail member is insertable into the grove to support a bottom portion in the furniture. The rail member further comprises a web, which abuts the frame sidepiece, when the first flange has been inserted into one of the grooves, and a second flange connected to the first flange and/or the web of the rail member and extending outwardly from the frame sidepiece. The first flange forms an acute angle in the range of 15°-75°, preferably 30°-60°, with the web. The grooves formed in the frame sidepieces are correspondingly inclined and free of internal lining. As a result a very simple and inexpensive piece of furniture is obtained. The construction further allows a reliable adjustment in height of the bottom portion and makes it possible to maintain the profiled rail member in the frame sidepieces without using separate fastening means.

Claims

1. A piece of furniture, such as a bed or a chair, comprising:

a substantially rectangular frame having two elogated frame sidepieces, a plurality of parallel, elongated grooves in surfaces of said sidepieces which face each other, two elongated profiled rail members, each rail member having a first flange inserted into a groove of the respective frame sidepiece, each rail member further comprising a web abutting the respective frame sidepiece, and also having a second flange extending outwardly from the respective frame sidepiece towards the other sidepiece, for supporting a furniture bottom portion, each first flange forming an acute angle in the range from 15°

to 75°

with its respective web, the grooves in the frame sidepieces forming a corresponding angle with the sidepiece surface, being free of an inner lining, and mounting means for strengthening the respective frame sidepiece, said mounting means being provided on and abutting the surface of the frame sidepieces at opposite ends thereof, said mounting means having spaced slots of approximately the same width as the grooves in the respective frame sidepiece, the first flange of the member extending into said slots and the web abutting the mounting means.

2. A piece of furniture as claimed in claim 1, wherein the range is from 30°

to 60°

.

3. A piece of furniture as claimed in claim 1, wherein the web has bores for screws for fastening the rail member onto the respective frame sidepiece.

4. A piece of furniture as claimed in claim 1, wherein the depth of the groove is greater than the width of the first flange, the groove having a bevelled edge at said corresponding angle.

5. A piece of furniture as claimed in claim 1, wherein each mounting means comprises two integral parts perpendicular to each other, one of said parts having said slots and the other abutting an edge of the respective frame sidepiece.

6. A piece of furniture as claimed in claim 5, wherein said mounting means is of substantially the same height as the frame sidepiece, and wherein said one mounting part is of a length in the range of 10-50 mm.

7. A piece of furniture according to claim 6, wherein said range is 12 to 25 mm.

8. A piece of furniture as claimed in claim 1, wherein the slots are dimensioned and positioned relative to the grooves such that stress on the rail member at its ends is transferred to the mounting means.

9. A piece of furniture as claimed in claim 1, wherein one rail member is positioned higher than the other for supporting a furniture bottom portion at an angle.
