Definitions

  • the present invention refers to an improved kind of height-adjustable foot, in particular an adjustable foot as used to adjust the installation height of furniture pieces and similar cabinets standing on respective resting surfaces, such as of course a floor.
  • Adjustable feet are largely known as such in the art; they are generally comprised of two elongated members that are inserted into each other and are able to slide axially relative to each other with a telescopic kind of motion.
  • One of these members is firmly joined to a base that rests on the floor, whereas the other member is adapted to engage a portion of the cabinet. Most obviously, the displacement of these two members relative to each other determines a corresponding displacement of the same cabinet so as to adjust the installation height thereof.
  • the sliding motion of the two members relative to each other is generally actuated through a screw-and-nut screw mechanism that can be operated in a variety of manners.
  • the cabinet itself be additionally machined in a corresponding manner in view of providing an accommodation adapted to receive said foot, as noted above.
  • an adjustable foot that is formed by the combination of a base member, or foot, to which there is firmly joined a threaded stem, a sleeve-like actuation member provided with a terminal axial toothing and coupled to the threaded stem of the foot, and a liner-like support member for the actuation member;
  • this patent is extensively discussed in the aforementioned Italian patent No. 01249605 to CAMAR SpA, along with the various drawbacks of the adjustable foot covered by it, so that - for obvious reasons of brevity - it shall not be discussed here any longer.
  • This adjustment mechanism is comprised of a crown gear provided at the free end portion of the screw, to which crown gear there is coupled a pinion that is operable from the outside with the help of a proper tool.
  • the load weighing on the foot passes through the bearing function provided by a suitable collar accommodated in a corresponding annular groove in the half-shells. Since this bearing occurs between two planar, mutually sliding surfaces, the resulting friction is quite significant and, therefore, tends to generate a considerable resistance that hampers the adjustment manoeuvre.
  • an adjustable foot according to the present invention comprises:
  • Said outer shell 1 is further provided with bracket-like projections, in the form of lugs or the like, on which there is capable of resting a lower or bottom portion of the cabinet 6.
  • said adjustable foot is fitted from the bottom into an appropriate elongated accommodation provided in the cabinet, while said projections 5 move into abutting - from the bottom - against the outer portions of the cabinet surrounding said accommodation.
  • the inner cylindrical body 3 joins firmly with the resting base 7 of the adjustable foot.
  • a device for transmitting a rotary motion comprising:
  • a crown gear 9 adapted to couple with a pinion 10 arranged thereupon; said crown gear and said pinion are provided and arranged relative to each other in such manner as to ensure that, if the crown gear rotates with the respective fluted member 8 and, hence, about a vertical axis, the pinion 10 will rotate about a horizontal or slightly inclined axis Y.
  • a short shaft 11 Connected to said pinion 10 there is additionally a short shaft 11, within which there is provided an appropriate bore 12 for receiving a manoeuvring tool, by means of which said pinion and - via said crown gear - also said fluted member and, as a result, said inner cylindrical body can therefore be caused to rotate.
  • Said manoeuvring tool (not shown) can reach the pinion by passing through an appropriate aperture 13 provided in the outer shell.
  • a top locking cap 14 On the upper mouth of said outer shell there is arranged a top locking cap 14, which is provided with an appropriately shaped lower portion adapted to cause said short shaft 11 to get engaged against the wall of said outer shell in such a manner as to keep said pinion in the correct position thereof, while allowing it to rotate by causing said pinion to correspondingly engage said crown gear 9.
  • said locking cap 14 is provided with appropriate elastic tabs 15, so as to be able to be snap-fitted into corresponding slits 16 provided in said outer shell.
  • this fact has the advantage that the same load does not pass through the rotatably driving mechanism comprising the crown gear 9, the pinion 10 and the shaft 11, thereby facilitating the actuation of the same mechanism and the rotation thereof to be brought about, without affecting the proper operation of the adjustable foot.
  • said inner cylindrical body is provided by combining the following three distinct elements with each other, i.e.:
  • said third and forth threadings 21 and 22 are provided with a pitch that is smaller than the pitch of said first and second threadings 2 and 4, and are oriented so that, when said inner body moves downwards along said outer shell (due to the action of the screw-and-nut screw mechanism), said hollow cylindrical projection 19 will move upwards along said lower cylindrical protrusion 20.
  • the lower portion of said outer shell and said hollow cylindrical projection are provided with mutual engagement means, preferably axially (vertically) sliding locking keys or splines 23, as best shown in Figures 4 and 6, adapted to allow said projection and said protrusion to displace axially relative to each other, while preventing them to rotate relative to each other.
  • FIGS 15 through to 18 illustrate a variation in the construction of the embodiment illustrated in Figures 9 and 10.
  • This variation practically consists in symmetrically inverting the geometry of the previously described construction. That is, while in the previously described solutions there is provided the lower cylindrical protrusion 20 that fits into the hollow projection 19, wherein third and fourth threadings 21 and 22, respectively, are provided on the mutually opposing surfaces of said projection and said protrusion, the present variation consists in modifying said projection 19 by converting it into a projection 19A that is no longer hollow, but rather solid, extending with the upper portion 19B thereof into a recess 20A provided from the bottom upwards into said inner cylindrical body 3, which most obviously is in this case deprived of the respective protrusion 20, as replaced by said recess 20A.
  • the outer surface of the projection 19A is provided with a respective fifth threading 21A, while the inner surface of the recess 20A is in turn provided with a corresponding sixth threading 22A.
  • said projection 19A and the lower portion of said outer shell are so shaped as to prevent said projection 19A and said recess 20A from being capable of rotating relative to each other.
  • a washer or a step-like shoulder 24 which may then constitute a support for the lower edge of the crown gear 9 to rest thereupon, and therefore prevents the fluted member 8 from moving downwards in an uncontrolled manner.
  • said outer shell 1 it would in this case prove certainly quite difficult for said outer shell 1 to be processed, i.e. machined from the interior thereof after it has been formed, e.g. die-cast, for reasons that are well known to all those skilled in the art.
  • said outer shell 1 is practically made out of a combination of two half-shells 1A and 1B, which are substantially symmetrical relative to a median vertical plane passing through the axis of the foot, and which are produced separately and independently to be then associated to each other, i.e. assembled together with the use of means that are generally known as such in the art, e.g. by means of a cotter 26 and related tapered hole 27 provided on the respective ones of said two half-shells.
  • this solution based on having the outer shell divided into two distinct half-shells 1A and 1B - although effective in solving the problem connected not only with the production of a foot of metal material, but also with the need of providing the desired threading 2, which can in fact be provided automatically, i.e. integrally during forming in the case of the two half-shells - gives however rise to a drawback in that the two half-shells are less resistant to load altogether, especially when this load is unbalanced, due to their inherent non-monolithic structure.
  • a further improved embodiment of the outer shell is provided, which is practically based on having said outer shell provided in the form of a single half-shell adapted to accommodate all afore-described devices thereinside, but provided with an aperture 30, resembling a window opening into the interior of the shell, in correspondence to the inner threading 2; this window must be positioned at such height as to substantially correspond to the position of said inner threading 2, and must be adequately high and wide, i.e. sized, as to allow the single shell 1 to be produced in a single die-forming operation, including forming also the portion of threading 2 that corresponds to the inner surface of the shell, except of course for the portion corresponding to said aperture 30.
  • an appropriate cover 31 is produced separately for subsequent application on to said aperture 30 in such manner as to close it completely.
  • This cover 31 is furthermore threaded internally so as to provide it with an inner threading 2A in a manner corresponding to the inner threading 2 of the shell 1, so that when this cover 31 is duly and correctly positioned to close the aperture 30, the two threadings 2 and 2A join with each other to form a single coherent threading.
  • FIG. 12 a further advantageous variation in the embodiment of the adjustable foot according to the present invention is illustrated.
  • This variation consists in giving the outer shell 1 a typically rectangular cross-sectional shape R in various proportions (and hence even a square shape), while leaving all other shapes and sizes of the other afore-illustrated members and devices making up the foot unaltered.
  • This solution applies practically to those cases in which the foot is not applied under the cabinet and operated from the interior of the same cabinet, but is rather applied under a partition wall resting on the floor.
