Abstract
Description
- The present invention relates to drawers for furniture, having the side panels made each of a single extruded aluminium draw piece.
- There are known wooden drawers the sliding of which within the seat which houses them is made easier by metal guides being applied to both sides thereof and designed to slide between two rollers, the lateral guides being provided at their ends with removable clamping devices suitable to impede that the drawer is involuntarily taken out of its seat. Because of the presence of these clamping devices consisting generally of levers with detents, which levers are consideraby bulky, these wooden drawers cannot be wholly pulled out in the customary utilization, so as to show the entire contents thereof. The drawer rear part comprised between the said detent and the rear side remains in fact inside the seat, compelling the user to almost blindly search in the drawer with his hands to take out the contents of that portion.
- These wooden drawers, moreover, have a reduced working width because of the presence of the metal lateral slide guides, extending into both side spaces designed to receive them.
- There are also known metal drawers obtained through the shaping of sheet irons, which are provided, at their longitudinal sides, with one or more ribs suitable to run in corresponding grooves made on the inner walls of the piece of furniture, made of metal too. These metal drawers have however, among other things, the inconvenience of being very heavy, besides sliding some times with difficulty, in consideration of the absence of rotating elements and of the relative deformability thereof as a consequence of blows or clumsy handling.
- The object of the present invention is therefore to provide a drawer of limited weight, dimensionally stable, having an optimal capacity with respect to its sizes. The drawer according to the present invention consists of four side panels cut out from a single a luminium draw piece, reciprocally coupled at their ends by four angled elements made of a stiff plastic material, which are provided with orthogonal extensions to fit corresponding seats consisting of longitudinal through holes provided in the upper and lower portions of the extruded aluminium draw piece, the middle part of the draw piece itself being C-shaped and outwardly open.
- The middle portion of the C-shaped aluminium draw piece slides, thanks to ball bearings being put in between, on a guide integral with the furniture seat and wholly received inside the C-shaped portion.
- The present invention will now be illustrated in more detail on the basis of the accompanying drawings of two preferred embodiments, in which:
- FIGURE 1 shows an exploded view of a first embodiment of a drawer according to the present invention and of the corresponding lateral slides; ,
- FIGURE 2 shows a schematic perspective view of the drawer of figure 1, in the assembled state;
- FIGURE 3 is the cutaway view of a first aluminium draw piece;
- FIGURE 4 is the cutaway view of a second aluminium draw piece;
- FIGURE 5 is the cross section of a first lateral slide guide;
- FIGURE 6 is a partially cut away view of a ball bearing provided with a circumferential groove for running along the guide of figure 5;
- FIGURE 7 is a partially cut away view of a second type of ball bearing;
- FIGURES 8, 8a, b and c are four views, namely front, side, back and plan view, respectively, of an angled front element to be assembled with the draw piece of Fig. 3;
- FIGURE 9 is a perspective view of an angled element to be assembled with the draw piece of figure 4;
- FIGURES 9a, b and c are three views, namely front, side and plan view, respectively, of the angled element of figure 9;
- FIGURES 10, 10a, b and c are four views, namely front, side, back and plan view, respectively, of an angled rear element to be assembled with the draw piece of Fig. 3;
- FIGURE 11 is a perspective view of a rear angled element to be assembled with the draw piece of figure 4;
- FIGURES 11a, b and c are three views, namely front, side and plan view, respectively, of the angled element of figure 11.
- As can be seen in figures 1 and 2, the drawer according to the present invention consists of four
portions angled elements 2, as well as by a bottom support and closure plane surface 7. Thedrawer sides guides - As can be seen in figures 3 and 4, relating to two different embodiments of the draw piece according to the present invention, but based non et he less on the same working principle, the draw piece comprises three distinct parts, namely an upper part 8, 8′ of a closed box-like shape, a lower part 9, 9′ which, according to the embodiment of figure 3, is of closed box-like shape too (9), whilst in the embodiment of figure 4 it merely consists of an L-
shaped extension 24, as well as a substantially C-shapedmiddle part middle parts rectangular apertures 11 of the same shape, whilst below the lower part 9, 9′ there is an L-shaped extension 24. - Figure 5 shows the section of an angle, still made of extruded aluminium, forming side supporting and sliding
guides Guides - Figures 6 and 7 show, partially cutaway, the side profiles of the two
ball bearings draw pieces 4 and theside guides ball bearings pins 15. The ball bearing 13 has acircumferential groove 16 designed to engage the roundish jut 12 of theside guides - Figures 8 to 8c and 9 to 9c show different views of angled elements of rigid plastic material intended to engage the hollow box-like upper and lower parts 8, 8′, and 9, 9′, respectively, of
draw pieces 4 to form the front corners of the drawers according to the invention. These angled elements 1 have each fourextensions draw pieces 4. The angled element of figure 9 has also other fourextensions 18 with rectangular section, intended to be forced through betweenvertical projections 19 and the vertical wall of the C-shaped middle wall 10′ in the draw piece of figure 4. - The rear
angled elements 2 shown in figures 10 to 10c and 11 to 11c are structured substantially as the front angled elements of figures 8 to 8c and 9 to 9c, with the difference that they further have a rearflat extension 20 on which is pivoted one of the ball bearings of figures 6 and 8 as well as a lower contrast roller and that, in theangled element 2 of figure 11, to the pairs ofextensions 18 of the element of figure 9 there correspond widersingle extensions 18, whilstextensions 17′ are missing. - A ball bearing 13 with circumferiential groove is outwardly mounted in the proximity to the outermost end edge of the
rear extension 20, and a second ball bearing 14 is inwardly mounted, still by means of a pin for pivoting, in the proximity to the forward end of thelateral guide 5. Another pair ofball bearings rear extension 20 of the secondangled element 2 and of theangle slide guide 6. - The mounting of the different pieces, carried out in the way as previously described and illustrated by the exploded representation of figure 1, allows to obtain a drawer such as the one schematically sketched in figure 2. The
circumferential grooves 16 of theball bearings rear extension 20 of theangled elements 2 and on the front end of theside guides elements 23 made at the ends of the C-shapedcentral part - Likewise, a pair of
ball bearings ball bearings rear extension 20 of the secondangled element 2 and on theside angle 6, pivotally engage, at one side, the shorter side ofangle 6 and, at the other side, the said hookedelements 23 of thedraw piece 4′ . - To the purpose of avoiding that an abrupt removal of the drawer from its seat, whereby the pairs of
ball bearings pieces angled elements 2, 1, respectively, there is the provision for self-tappingscrews 22 to be screwed across the body of theangled elements 1, 2 onto thequadrangular apertures 11 of the draw pieces, both lengthwise and crosswise. - The bottom supporting and closing plane of the drawer should be inserted, after assembling three side panels of the, drawer, in the suitable inner peripheral groove provided by the L-
shaped extension 24 ofdraw pieces - Although the present invention has been illustrated on the basis of some preferred embodiments thereof, it is obvious that variations and/or amendments could be made thereto by those skilled in the art without departing from the scope of the invention itself.
