DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a carcase for assemblable furniture, e.g. of the cupboard, counter and/shelf type, and includes at least two carrying frames with bottom and top members.
As is well known, furniture exists in a number of different forms and variations for a number of different purposes, but in a usable state all furniture is regarded in principle as very voluminous as freight. There is, however, assemblable furniture that is delivered from the factory via furniture shops to the customer, and which is packaged in a knocked-down state, the customer then having to look after the assembly of the different parts into a finished piece of furniture, either personally, or with the help of experienced persons. Assemblable furniture thus has the advantage that it can be packaged knocked down, and consequently it can be delivered in packages adapted for transport, i.e. such as have the least possible volume and greatest possible regularity, which of course are well suited to being stored.
Existing assemblable furniture, delivered knocked down for assembly in situ does not solely have advantages, and it is also burdened with disadvantages, above all with regard to the actual assembly, which often is complicated and impossible to accomplish single-handed. As well, there is also the situation that to achieve the necessary stability in such assemblable furniture when it is in an assembled state, a relatively large number of screw or bolt connections is required for joining the different parts together in a stable manner. These connections, necessary for joining the parts together, make manufacture substantially more expensive and assembly complicated, not least because special tools are also required for them. It has further been found that there are great problems in situating the parting places such that required strength is obtained as well as parts that have shapes enabling packaging adapted to transport and storage. Most often, both these demands can not be met, and certain compromises occur in one direction or the other.
The object of the present invention is therefore to achieve an assemblable carcase for furniture that does not have the mentioned drawbacks, and is simple to assemble, even for a single person, and which does not require any special screw or bolt connections to obtain the necessary stability of the furniture in question in its assembled state, as well as being able to be packaged in a manner suited to transport and storage.
This object is achieved by the carcase in accordance with the present invention having been given the characterising features disclosed in the accompanying claims.
The invention will now be described in more detail, and with reference to the accompanying drawings, where
FIG. 1 illustrates parts in an embodiment of the carcase intended for cupboards, benches and shelves,
FIG. 2 is a side view of a carrying frame included in the carcase, as seen from the inside,
FIGS. 3 and 4 respectively illustrate, to a larger scale and seen from the outside, an upper and a lower corner of a carrying frame,
FIG. 5 is a section along the line V--V in FIG. 3,
FIGS. 6 and 7 are respectively a section along the line VI--VI in FIG. 3 and a section along the line VII--VII in FIG. 4,
FIGS. 8-11 are perspective views of different stages in assembling a carcase in accordance with the invention,
FIGS. 12 and 13 are respectively a front view and an end view of a cupboard with a modified carcase in accordance with the invention,
FIG. 14 is a horizontal section through an inventive carcase in an alternative embodiment of the carrying frame posts and the top and bottom members, and
FIG. 15 is a horizontal section through an inventive carcase in an alternative embodiment of the carrying frame posts and end sides.
In accordance with the invention the carcase includes a front carrying frame 1 and a rear carrying frame 2, and in the embodiment according to FIGS. 1-11 they are made identically alike, but this is not necessary, as will be seen, inter alia from FIGS. 12 and 13. Each carrying frame 1,
