DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a collapsible cabinet, comprising end ladder structures mounted on the gables of said cabinet and door frame structures, both structures including upright posts and horizontal braces therebetween, the latter being fastened between the upright posts for keeping said upright posts parallel to and spaced from each other, the horizontal braces and upright posts thus defining rectangular areas, whereby the sides of horizontal braces and upright posts facing such areas are provided with a groove for receiving cover boards that cover said areas.
An advantage offered by this type of cabinet is that it can be manufactured by using relatively few standard elements and assembled readily and quickly on site. Another advantage is that a variety of cabinet designs can be assembled by using a relatively limited selection of elements.
In the prior art cabinets, only some of these advantages are achieved since the end ladders as well as cabinet doors have generally been prefabricated, which means that their price is relatively high and their size imposes certain limitations to the reduction of the size of a shipping package. Variation possibilities are also limited.
An object of the invention is to develop a cabinet of the above type further, so that the end ladders and doors can also be assembled readily and quickly from prefabricated elements and that the number of various elements can be further decreased while, at the same time; providing flexible and extensive variation possibilities for assembling various types of cabinets from few prefabricated, extremely simple basic elements.
In order to achieve this object, a cabinet of the invention is characterized in that the horizontal braces of end ladders are fastened between the broad sides of upright posts by means of screws extending through said upright posts, in addition to which the broad sides of upright posts are provided with arrays of holes, extending on either side of the ends of horizontal braces. The doors are also assembled by fastening the horizontal braces by means of screws extending through the upright posts. A particularly preferable embodiment of the invention is characterized in that the rectangular area defined by the bottom of said grooves is of equal size in the end ladder and in the door frame structure, both of said areas being fitted with cover boards of a single standard size.
The cover boards for end ladders and doors can be prefabricated from the same type of board in one standard size, the only variable being the colour.
Another object of the invention is take advantage of the special structure of an end ladder in a manner that various supports and fasteners, such as support and runner tracks for drawers, door hinges, clothes hanging rods and hooks and the like, can be mounted in a simple manner, quickly and readily in their desired positions, which positions can be freely chosen in vertical direction.
In order to achieve this object, a fastening assembly of the invention is characterized in that said supports or fasteners are secured to or formed integrally with a fastening piece, whose ends are provided with holes or recesses for inserting therein the pegs fitting in the holes of said arrays of holes.
The invention will now be described in more detail with reference made to the accompanying drawings, in which
