Definitions

  • the present invention relates to an extensible leg, in particular, but not exclusively, for furniture peninsulae, equipped with a typical safety lock means.
  • tubular portion which is designed to rest on floor is also equipped with a fine adjustment-levelling device (commonly referred to as "adjusting foot”), used to compensate for very small level differences, for example deriving from floor irregularities.
  • adjusting foot a fine adjustment-levelling device
  • a first drawback is represented by the relatively low safety level offered by the system, because the lock secured by the bayonet coupling is labile: in fact, in order to release said lock a rotation is in fact sufficient -- even an inadvertent rotation, for example during a leg cleaning, or caused by a child -- of either tubular portion relatively to the other, causing a sudden downwards falling of the supported peninsula, with evident risk of physical damage to possibly present people.
  • the purpose of the present invention is of obviating the drawbacks which affect the prior art, by providing an extensible leg, in particular for furniture peninsulae, which, besides being provided with an extremely safe system for locking the leg at the desired height, does not require any additional devices for fine adjustment-levelling.
  • the leg according to the present invention is generally indicated with the reference numeral (10) and is structurally formed by a first tubular element (11) with a free end designed to rest on the floor, and a second tubular element (12), interlinked with the first tubular element (11), with a free end designed to be fastened by means of a flange means (13) to a table top (not represented in figures), e.g., the peninsula of a furniture piece.
  • the second tubular element (12) is provided with a screw-thread as shown in (14) and gets screwed on a sleeve (15) displaying a screw-thread in (16), integral with the first tubular element (11).
  • Said sleeve (15) is furthermore provided with an extended portion (17) protruding from the tubular element (11) and externally screw-threaded in (18) ( Figures 3 and 4).
  • a locking ring-nut (19) screw-threaded in (20) gets inmeshed; with a split lock element of conical shape (21) being translatably, but not rotatably, constrained to said ring-nut (19).
  • Said split lock element of conical shape (21) is split in (22) and is wedged in between said second tubular element (12) and the complementary internal surface of the extended portion (17) of the sleeve (15) integral with said first tubular element (11).
  • the system when it has reached the desired height and adjustment condition, the system can be stably locked, in positive mode, by rotating the ring-nut (19) in that direction which will cause the split lock element of conical shape (21) to translate to its position as shown in Figure 4, in which it is wedged in between the tubular element (12) and the sleeve (15).
  • the purpose recited in the preamble to the disclosure of providing an extensible leg with safety locking system at the desired height and in which a fine enough adjustment having the purpose of levelling and compensating for possible small floor unevennesses, can be performed with no need ror providing said leg with a further adjustment device (adjusting foot), is achieved.
