Abstract
A side guide structure for the drawers of a drawer unit
includes a substantially flat frame (8a, 8b) and a first series
of rectilinear, parallel guides (10) extending from a first
face of the frame (8a, 8b) and defining a first series of
support and sliding seats for drawers (5). The structure
includes a second set of rectilinear parallel guides (12) that
extend from the second face of the frame (8a, 8b) and define a
second series of support and sliding seats for drawers (5).
Description
- The present invention generally relates to components for drawer units.
- More particularly, the invention relates to a side guide structure for the drawers of a drawer unit, including a substantially flat frame and a first series of parallel, rectilinear guides that extend from a first face of the frame and define a first series of support and sliding seats for drawers.
- In drawer units, the furniture body has inside it a plurality of guides that sustain the drawers and enable them to slide with respect to the furniture body between a closed position and an open position. Usually, these guides are connected to a pair of lateral frames of the drawer unit and are positioned with respect thereto depending on the number and height of the drawers present in this kind of drawer unit. In some cases, the sliding guides for the drawers can be coupled with seats conveniently located on particular frames so that the frames, together with the associated guides, can be made during the assembly of the drawer unit depending on the number and dimensions of drawers to be used.
- In summary, in the prior art, each side guide frame for a drawer unit is manufactured before or during the assembly of the furniture with a single series of guides that extend from a face of the frame, the number and disposition of which depend on the kind of drawer unit to be manufactured. In this way, it is necessary to provide a pair of specific frames, one for each side of the unit, for each kind of drawer unit.
- However, in the mass production of furniture, a single furniture body is frequently used for a range of different arrangements of components. For example, a drawer unit having standard external dimensions that can be included as a furnishing component in a series of other furniture units of the same furnishing line, can have a different number of drawers of various heights depending on the intended use of the unit.
- In this case, the necessity of providing a pair of different side guide structures for each different drawer of the drawer unit, irrespective of whether the dimensions of the furniture unit remain the same, leads to an increase in the production and storage costs of the various components of the drawer units.
- In order to overcome this disadvantage, the object of the invention is a side guide structure of the type defined above, characterised in that it includes a second series of parallel rectilinear guides that extend from the second face of the frame and define a second series of support and sliding seats for drawers.
- By virtue of this arrangement, a guide structure according to the invention is more versatile in its application as it enables the same frame to be used for the same furniture body in two different assembly arrangements. For example, a guide structure according to the invention, the frame of which has the series of guides of the two sides of the drawer unit on its two opposite faces, respectively, can be utilised on either side of the same drawer unit.
- Preferably, the second series of guides includes a number of guides different from that of the first series of guides.
- In this way, the same guide structure can be installed on one side of two kinds of drawer unit having different numbers of drawers, utilising the first series of guides on one of its faces, or the second series of guides on the other face to guide the drawers.
- By virtue of the invention, it is in particular possible to reduce significantly the production and storage costs of the guide frames for the mass production of the drawer units.
- Further characteristics and advantages of the invention will become clearer from the following detailed description, given purely by way of non-limitative example and made with reference to the accompanying drawings in which:
- Figure 1 is a schematic exploded perspective view of a first kind of drawer unit provided with side guide structures for the drawers according to the invention, in which the guides on a first face of the guide structures are used,
- Figure 2 is a view similar to Figure 1 that illustrates another kind of drawer unit with the drawer guide structures of Figure 1, utilising the guides on the other face of the guide structures,
- Figure 3 is a front view on an enlarged scale of a section of a drawer guide structure taken along the line III-III of Figure 1,
- Figure 4 is a side view of the structure of Figure 3 taken in the direction of the arrow IV, and
- Figure 5 is a view from above of the structure of Figure 4, with a section taken along the line V-V.
-
- With initial reference to Figures 1 and 2, a pair of drawer units, both having the
same body 3, are respectively indicated 1a and 1b. Thebody 3 of thedrawer units upper panel 3a, alower panel 3b, a C-shape half-shell defining a back wall of the drawer unit (not seen in the drawings) and a pair ofside panels panels drawer units - In particular, the
drawer unit 1a includes a series of sixdrawers 5 of equal height, while thedrawer unit 1b has fourbottom drawers 5 that are the same as those of thedrawer unit 1a, twoupper drawers 5a the height of which is smaller than that of thedrawers 5, and threedrawers 5b arranged between thedrawers drawers drawer units - In order to enable the support and sliding of the drawers of the
drawer units body 3, each unit includes a pair of side guide structures, indicated respectively 8a and 8b, that are assembled in arespective side panel body 3, as illustrated more clearly in Figure 5. - Each
guide structure panel body 3. - Each
frame parallel guides 10 that extend transversely on a first face thereof, and a second series ofrectilinear guides 12, these also being parallel, that extend transversely on its other face, an associated drawer support and sliding seat being defined between each pair ofguides guide - In the embodiment illustrated in the drawings, each
frame - In the specific case, both of the
frames drawers 5 by means of theguides 12 and, on the opposite face, seats for ninedrawers guides 10, there being tenguides 10 in order to define the nine seats for the drawers, while there are sevenrectilinear guides 12 to define the six drawer seats. The structure of theframes - Each
rectilinear guide guides guides 12, which structurally strengthens theframes - In the embodiment illustrated of rectangular frames, the pillar-
like formations guides frame first pillar 11a adjacent the pillar-like formation 11, asecond pillar 13a adjacent the pillar-like formation 13, as well as anintermediate pillar 15 equidistant from thepillars - The structure of the
frames rectilinear guides auxiliary pillars - Preferably, the rectilinear guide at the top of each sliding seat has a safety device to prevent the drawer coming off the guide, comprising a sprung
flap 18 one of the ends of which projects from the side of the respective drawer seat. In addition, one of the two guides of each drawer seat, for example the top one, has an endstop shoulder element 20 constituted, for example, by a projection that projects towards the seat close to its rear portion to act as a stop for the drawer sliding in the respective seat. - Advantageously, each
frame guides flaps 18 and theshoulder elements 20, the pillar-like formations auxiliary pillars - By virtue of the invention it is therefore possible to utilise a single pair of
specular frames
