Definitions

• the present invention relates to a levelling device for a piece of furniture, or for parts of a piece of furniture.
• Furniture or pieces of furniture refer to at least one horizontal or base element and at least one vertical or shoulder element firmly joined together, perpendicular to each other, whose position must be adjusted with respect to a supporting surface or floor, even when the space between the base of the furniture and the floor is small.
• the levelling device according to the invention is of the type adjustable from above and from inside the furniture and is applied to furniture in which the lower or underlying surface of the base is substantially coplanar with the lower edge of the shoulder.
• the general objective of the present invention is to provide a levelling device having a structure which is such as to guarantee both the support of the vertical or shoulder element and an ample height adjustment, with a height equal to, or even greater than the distance between the base and the floor.
• a further objective of the invention is to provide a levelling device provided with an adjustable foot, which is stably and safely guided between the two extreme positions, i.e. fully withdrawn and completely extracted.
• FIG. 1 and 2 are two vertical sections illustrating a first embodiment of a levelling device applicable to a piece of furniture, or to parts of a piece of furniture in two different operating positions;
• FIGS. 3 and 4 are two perspective views from above and below respectively, illustrating the levelling device alone of figures 1 and 2;
• FIGS. 5 and 6 are two plan views from above and below respectively, illustrating the levelling device of figures 3 and 4 ;
• figure 7 is a raised longitudinal view according to the arrow F of figure 6;
• figure 8 is a raised cross-sectional view according to the arrow FI of figure 6;
• figures 9 and 10 are two vertical sections illustrating a second embodiment of a levelling device applicable to a piece of furniture, or to parts of a piece of furniture in two different operating positions;
• figures 11 and 12 are two perspective views from above and below respectively, illustrating the levelling device alone of figures 9 and 10;
• FIGS. 13 and 14 are two plan views from above and below respectively, illustrating the levelling device of figures 11 and 12 ;
• figure 15 is a raised longitudinal view according to the arrow F of figure 14;
• figure 16 is a raised cross-sectional view according to the arrow FI of figure 14;
• FIGS. 17 and 18 are two vertical sections illustrating a third embodiment of a levelling device applicable to a piece of furniture or parts of a piece of furniture in two different operating positions.
• FIGS 1 and 2 illustrate a first exemplary and non limiting embodiment of the invention in which a levelling device 10 is applied to a piece of furniture M which must be levelled with respect to a supporting surface or floor P.
• the lower or underlying surface S of the base 11 and the lower edge B of the shoulder 12 are substantially coplanar with each other, i.e. they lie on the same plane which is parallel and interspaced with respect to the floor P.
• the base 11 and the shoulder 12 are firmly joined together by means of joining systems of known type (not shown), with the edge B1 of the base 11 abutted against the inner surface SI of the shoulder 12.
• the levelling device 10 is structurally composed of a rigid plate 13, for example made of plastic, metal, or other material suitable for the purpose, having a substantially rectangular elongated plan configuration.
• Respective reinforcing ribs (skirts) 14 are formed integrally and extend downwards at 90° from the longitudinal edges of the plate 13.
• Said seat 15 has a first truncated-conical section 17, extending from the plate 13 which ends with a second cylindrical section 18, internally threaded, on which the above-mentioned foot 16 is threaded externally.
• the foot 16 can be optionally provided at the outer end with a pad 19 for resting on the floor P, and at the inner end, opposite the pad 19, said foot 16 is provided with a run-end stop 20 of the thread to prevent the downward extraction of the foot 16 itself from its seat 15.
• the plate 13 is also provided with fixing means 21 which extend upwards in a position opposite to the seat 15, and which serve for firmly fixing the levelling device 10, under the base 11, as clearly illustrated in the drawings.
• Said fixing means 21 can, for example, be those known in the field as “doubels", which are radially yielding and which are forcibly pressed into complementary holes 22 and are expanded radially by means of an expansion screw 23, so as to cling permanently to the base 11.
• FIGS. 5 and 6 of the drawings clearly show how the seat 15 of the adjustable foot 16 and the fixing means 21 are aligned along the same longitudinal symmetry axis X-X of the plate 13.
• the fixing means 21 are interspaced by an equal distance d from the symmetry axis Y-Y of the seat 15, said axis Y-Y however being offset (eccentric) with respect to the transverse symmetry axis Z-Z of the plate 13.
• a section or flap 24 is defined on the plate 13 which protrudes from the base 11, the lower edge B of the shoulder 12 resting, at least partially, on said section 24 (figures 1 and 2) when the levelling device 10 is fixed under the base 12, in an operating position.
• the levelling device 10 can be operated from above using a key 25 which, passing through a pass-through hole 26 of the base 12 engages with the upper free end of the foot 16 with a corresponding imprint.
• the foot 16 can be screwed into its threaded seat 15 between the fully withdrawn (figure 1) and completely extracted (figure 2) extreme positions; the distance h between the base 11 and the floor P can therefore be varied/adj usted, according to the stability requirements of the furniture M.
• the pass-through hole 26 is coaxial with the foot 16 and with the seat 15 and has a diameter slightly greater than the cross-section of the key 25.
• the number 27 indicates an aesthetic hole-covering cap.
• the internal end of the adjustable foot 16, and its completely withdrawn position is substantially adjacent to the lower surface S of the base 11, i.e. it can in no way penetrate within said base 11.
• FIGS 9-16 illustrate a second exemplary embodiment of a levelling device incorporating the innovative principles of the present invention.
• the second embodiment offers a greater height adjustment than the first embodiment, thanks to the fact that the adjustable foot 116 can penetrate a pass-through hole 126 of the base 111.
• said hole 126 has a slightly larger diameter than that of the adjustable foot 116, as can be clearly seen from figures 9 and 10 of the drawings.
• levelling device 110 of this embodiment of the invention is fixed to the base 111 only by means of screws 128, there being no "doubels".
• Figures 17 and 18 illustrate a third exemplary embodiment of a levelling device incorporating the innovative principles of the present invention.
• This third embodiment of the invention differs from the first two embodiments in that the seat 215 of the adjustable foot 216 consists of the truncated-conical section 217 alone, the cylindrical end section being absent.
