Definitions

  • the present invention relates to a connection apparatus, for connecting structural elements with selectively variable angle.
  • connection can advantageously be used in armchair construction technology, specifically referred to herein as an example of application.
  • a reference shall be understood to be by way of example only and does not limit the scope of the invention, since the connection in accordance with the invention can advantageously be used for general applications.
  • the sides of the armchair or sofa are normally rigid and fixed, allowing access to the armchair seat only from the front.
  • Such a structure is very disadvantageous for use of the armchair or sofa by people suffering from any motor limitation, particular of the lower limbs.
  • the side of the armchair with a single-piece fixed structure is also inconvenient for carrying out medical therapies which require the application, sometimes for a lengthy period (e.g.: dialysis), of therapeutic instruments to the arm of the person sitting on the armchair.
  • medical therapies which require the application, sometimes for a lengthy period (e.g.: dialysis), of therapeutic instruments to the arm of the person sitting on the armchair.
  • the Applicant has already developed a solution to such problems involving a particular type of joint which allows the production of side structures in at least two pieces which, when necessary, can be articulated relative to one another in such a way as to allow the upper part of the side to be dropped down relative to the lower part, for more convenient use of the armchair in all of its configurations for use.
  • Said solution substantially involves two members integrating coupling means designed to render the members monolithic relative to one another with unidirectional relative movement and alignment, along a first joint configuration direction; and disengagement means, for disengaging the coupling means and rendering the members movable relative to one another; the joint also comprises articulation means designed to allow the members, disengaged from one another, to be able to rotate and translate relative to one another in a guide until they adopt at least one stable position in which one of the members movable relative to the other which is considered fixed, is angled at least along a second joint configuration direction different to the first direction.
  • the aim of the present invention is therefore to overcome these disadvantages with a connection in which the connection state can be switched easily by the armchair user, without the need to lift and lower parts of the structure of the side and, in particular, by simply operating a push-button which can be operated with one finger.
  • the present invention also relates to a joint hinge, according to claim 9 and according to any of the claims directly or indirectly dependent on claim 9.
  • the invention also relates to a structural frame according to any of the claims from 10 to 19.
  • the numeral 25 denotes as a whole a structural frame designed to be fitted to a folding side 30 of an armchair 31.
  • the structural frame 25 basically comprises two structural elements 1 and 2, corresponding to two half-surfaces, interconnected rotatably about a shared direction of rotation 12, by a joint hinge 18 preferably located at the height of the armchair 31 seat 26 [Figure 2], there being the possibility of locking the hinge 18 in selectively variable angular positions, some of which are illustrated by way of example in Figure 3.
  • FIGS 4, 5 and 6 show in particular that the hinge 18 basically comprises a cylindrical tubular casing 16, at the ends of which there are two rotary connections 21, connected to one another by a rod 17 housed in the casing 16.
  • the two connections 21 are substantially located at the adjacent vertices 32 of the two half-surfaces 1 and 2.
  • Figures 7, 8 and 9 and, even more clearly Figures 9, 10 and 11 show how each connection 21 basically comprises: a cylindrical pin 3, with two bodies 4 and 5 consecutive and monolithic with one another.
  • a first body 4 has grooves on the outside.
  • the second body 5 is smooth.
  • connection 21 also comprises two arms 6 and 7 having corresponding ends 6a and 7a with holes 8 and 9 through them, delimited by surfaces 10 and 11 for surrounding the pin 3, grooved like the first body 4 and designed to fit together with it, with the possibility of relative linear sliding, parallel with an axial direction 12 of the pin 3.
  • the surfaces 10 and 11 which fit together are preferably cylindrical and are: convex on the first body 4, and concave on the holes 8 and 9 of the arms 6 and 7.
  • the arms 6 and 7 and the pin 3 can move relative to one another along the axial direction 12 of the pin 3, between two end positions, in a first of which the first, grooved body 4 of the pin 3 and the surfaces of the arms 6 and 7 are integral with one another with respect to the relative rotation about the direction of rotation 12 on the pin 3.
  • the second end position at least one of the arms 6 and 7 is at the second body 5 of the pin 3, so that it can rotate freely relative to the pin 3 and on the smooth surface of the second body 5 of the pin 3, while the other arm 6 or 7 continues to be integral with the pin 3, that is to say with its first body 4.
  • Each pin 3 comprises collars 13 for delimiting the end positions of the relative movement of the pin 3 and the arms 6 and 7.
  • the hinge 18 also comprises elastic reaction means 14 [Figure 6] interacting between the casing 16 and the rod 17, and means 20 for controlling the movement of the rod 17 relative to the casing 16. Said movement occurs due to the prevalence of a driving force applied to the rod 17, countering the opposite reaction of the elastic means 14.
  • the control means 20 can preferably be operated manually using a push-button and are designed, when operated, to control the movement of the pins 3 between the two end positions.
  • the arms 6 and 7 are engaged with the first, grooved body 4 without the possibility of relative rotation about the direction 12.
  • the two half-frames 1, 2 remain in this stable condition once one of the relative angular positions illustrated in Figure 3 has been assigned to them.
  • one of the arms 6 and 7 arrives on the smooth body 5 of the pin 3, so that the arm 6 or 7 can rotate freely about the direction 12, able to be positioned at any angle to the other arm 7 or 6 which is kept integral with the first body 4 of the pin 3.
  • the two half-frames 6 and 7 are able to move by rotating relative to one another, in this way allowing variations, in the side 30 of the armchair 31, in the angle of one half-frame 1 relative to the other half-frame 2.
  • the arms 6 and 7 of a connection 21 are associated with adjacent tubular elements 23 of the two half-frames 1 and 2 by axial insertion in the relative cavities.
  • the arms 6 and 7 remain centred in the cavity, in a stable condition, due to their projections 24 extending from each of the arms 6 and 7 parallel with the direction of rotation 12 of the hinge 18, making contact with the opposite inner walls of the tubular elements 23.
  • Figures 6, 7 and 9 show what is described below as regards operation of the relative rotation of the arms 6 and 7 which allows the half-frames 1 and 2 to be positioned with the desired relative angular orientation.
  • the hinge 18 is structured in such a way that there are two connections 21 aligned along the shared direction of rotation 12 of the half-frames 1 and 2 and integral with one another due to the presence of the rod 17 inserted between them, and if it is structured in such a way that the pins 3 of the two connections 21 are made in such a way that their first and second bodies 4 and 5 correspond in an orderly way along the shared direction 12 of the hinge 18, a single operation of rod 17 movement can be used to move both of the hinge 18 pins 3, so that the two connections 21 simultaneously reach the locking or free rotation position for one half-frame 1 relative to the other 2.
  • one of the pins 3 may advantageously have a front surface 15 designed to allow the armchair 31 user, with just the fingers of one hand, to push against the opposite force of the elastic means 14 so as to bring the hinge 18 to the switching conditions, that is to say, to a condition such that it allows the upper half-frame 1 of the side 30 to be angled even just by gravity and, if necessary with just the aid of a very limited horizontal push applied by the user with his body.
  • a front surface 15 designed to allow the armchair 31 user, with just the fingers of one hand, to push against the opposite force of the elastic means 14 so as to bring the hinge 18 to the switching conditions, that is to say, to a condition such that it allows the upper half-frame 1 of the side 30 to be angled even just by gravity and, if necessary with just the aid of a very limited horizontal push applied by the user with his body.
  • the invention fully achieves the expected results and has relatively simple construction, with evident advantages in terms of economical construction and safe, lasting operating reliability.
  • the latter features, to be hoped for in general, are even more appreciated considering that the invention is designed to be applied preferably, but without limiting the scope of the invention, in the padding of an armchair 31, no longer accessible from the outside after construction of the armchair 31.
