Abstract
The present invention relates to a mating modular element drawer construction for making quickly-assembled drawer assemblies, comprising at least an angular joint (6) for coupling two side elements (2,3,4) connected to one another by the angular joint, with expansion affixing means which are engaged in at least a seat (7) correspondingly defined on the side of the side element facing the angular joint.
Description
- The present invention relates to a modular drawer construction for making quickly-assembled drawer assemblies.
- As is known, the drawers for drawer assemblies and the like usually comprise four side elements, of which one constitutes the front element, and a bottom which are associated with one another by glueing, screw connections, fitting connections, or by coupling methods providing a combination of the above mentioned connection methods.
- In making drawers, one of the operations which requires a lot of time and accordingly affects the final making cost, is the assembling together of the side elements.
- In some types of drawers, in which as side elements there are used light alloy section members, the connection between these elements is performed by using angular joints, which are conventionally coupled to the two side elements by means of screws, which involves a comparatively long assembling time.
- Accordingly, the aim of the present invention is to overcome the above mentioned drawbacks by providing a drawer construction which can be simply and quickly assembled.
- Within the scope of the above mentioned aim, a main object of the present invention is to provide a drawer construction which, owing to its reduced assembling time, has a production cost which is much smaller than that of conventional drawers.
- Another object of the present invention is to provide such a drawer construction in which the side elements of the drawer can be easily connected to one another with a high accuracy.
- A further object of the present invention is to provide such a drawer construction which has a very high mechanical strength and duration.
- According to one aspect of the present invention, the above mentioned aim and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a mating modular element drawer construction for making quickly-assembled drawer assemblies and the like, characterized in that said drawer construction comprises at least an angular joint, connecting to one another two side elements of said drawer construction and including, on at least a side thereof facing one of said two side elements, expansion connecting means, engaged in at least a seat correspondingly defined on a side of said side element facing said angular joint.
- Further characteristics and advantages of the drawer construction according to the present invention will become more apparent from the following detailed description of a preferred embodiment thereof which is illustrated, by way of an indicative but not limitative example, in the accompanying drawings, where:
- Figure 1 is a perspective view of the drawer construction according to the present invention, the front side thereof being removed;
- Figure 2 is a perspective view illustrating the angular joint included in the drawer construction according to the present invention;
- Figures 3 to 5 illustrate, by respective perspective views, the drawer construction according to the present invention, during the assembling steps thereof;
- Figure 6 is a cross-sectional view of Figure 4 taken substantially along the line VI-VI; and
- Figure 7 is a cross-sectional view of Figure 5, taken substantially along the line VII-VII.
- With reference to the number references of the above mentioned figures, the drawer construction according to the present invention, which has been generally indicated at the
reference number 1, comprises side elements formed by twosidewalls back portion 4, supporting abottom 5, as well as a front element of known type and which, for simplicity, has not been shown. - The
sidewalls back portion 4 by angular joints, which have been generally indicated at thereference number 6. - Each angular joint is provided, on at least a side thereof facing one of the side elements, in the shown embodiment the
back portion 4, with expansion connecting means, which are engaged in at least a seat 7, correspondingly defined on the side of theback portion 4 facing theangular joint 6. - More specifically, said expansion connecting means are advantageously constituted by at least a
pin 8, defined bylugs 8a which are resiliently flexible, and apunch element 9, which can be introduced through apassage 10 passing through theangular joint 6 starting from the side of theangular joint 6 which is opposite to the side therefrom project thelugs 8a, and which is coaxial with respect to thepin 8. - Both the
pin 8, constituted by thelugs 8a, and thepunch element 9 have a polygonal crosssection and thepunch element 9 is provided, on its side surface, with longitudinal expandedportions 11, which can be engaged between thelugs 8a, as thepunch element 9 is engaged in thepassage 10. - As shown in the figures, there are provided preferably at least two
pins 8, on the side of theangular joint 6 facing the same side element, said pins being spaced from one another and being engaged in two seats 7, correspondingly defined on the end portion of the side element formed, in the shown embodiment, by theback portion 4. - Moreover, on the side of the
angular joint 6 facing theback portion 4, there are providedabutment legs 12, bearing on the outer side of theback portion 4, so as to favor the connection provided by thelugs 8a inside the seats 7. - The side elements of the drawer and, more specifically, the
sidewall 2 andback portion 4, are preferably constituted by light alloy extruded section members. Thus, the seats or recesses 7, defined in theback portion 4, will be directly made as the extruded section member is made. - The connection of the
angular joint 6 with thesidewall 2 is performed, in a per se known manner, by means ofscrews 13 which are engaged in seats suitably provided in the body of the section member forming thesidewall 2. - In this connection it should be apparent that on the side of the
angular joint 6 facing thesidewall 2 it is also possible to provideabutment lugs 16, engaging insaid sidewall 2. Moreover, both thesidewalls back portion 4 are provided with a bottom lug orleg 17 supporting thebottom 5. - The
angular joint 6 which can be made, at a very low cost, of a molded plastic material, supports moreover awheel 15 for allowing the drawer to slide along the sliding guides therefor provided in the drawer assembly, or the like, in a per se known manner and which for simplicity has not been shown. - The assembling of the above disclosed construction, according to the present invention, is very simple and quick. In fact, in order to connect to one another the
sidewall 2 and theback portion 4 it will be sufficient to connect, by thescrews 13, theangular joint 6 to thesidewall 2 and apply successively thepins 8 defined by thelugs 8a in the seats 7 formed in theback portion 4. - Then, in the
passages 10 of theangular joint 6 will be pressure engaged thepunch elements 9 so as to cause thelugs 8a to be bent away from the axis of thepin 8, and cause saidlugs 8a to be forcibly abutted against the inner surface of the seats 7, so as to connect the angular element orjoint 6 to theback portion 4. In this connection it should be apparent that, since the connection of theangular joint 6 to theback portion 4 can be performed by a simple pressing operation on thepunch elements 9, it will require a very reduced time, and, in particular, much smaller than that required for a screw connection. - From the above disclosure and from the figures of the accompanying drawings, it should be apparent that the invention fully achieves the intended aim and objects. In particular, the fact is to be pointed out that a drawer construction has been provided which can be assembled in a very reduced time and accordingly with a very reduced making cost, much smaller than that of prior drawers.
- In practicing the invention, the used materials, as well as the contingent size and shapes, can be any, depending on requirements.
