Definitions

  • the present invention relates to a device for removably connecting accessories to a bedstead, comprising: at least one pivot pin integral with a first component of a bed; at least one engagement element carried by a second component of said bed and having a seating adapted to house said pivot pin in order to afford a relative rotation between the first and second components about a predetermined pivot axis.
  • the presence of at least one mattress is conventionally provided, which is disposed on a spring support structure suitably engaged to a bearing framework or bedstead provided in turn with support elements resting on ground or bedposts.
  • the spring support structure forming the bed bottom sheet consists of a plurality of wooden laths or staves disposed side by side and connected at their ends to the bedstead.
  • the adjustable end portion or a different accessory element is provided at each end with at least one cylindrical pivot element axially fitted in an engagement element consisting of a tubular body integral with the bedstead.
  • a support for a mattress is placed in the space between the two structures.
  • the construction is made for having the support on the same plane than that of the two oscillating structures.
  • the solution to the above problem is that of forming the support by moulding with protuberances to be introduced in openings of the longitudinal elements of the bedframe.
  • the support comprises also seatings adapted to enable pivot pins of the structures to be fitted through access openings according to a predetermined orientation and to be angularly rotated.
  • connection between the pivot element and engagement element occurring in a radial direction or along an arc of a circle, for example from top to bottom instead of resorting to an axial fitting comprises a wing between the pivot and the engagement element to enable the surface of the accessory to conform in height to the support surface of the bed.
  • the invention relates to a device for removably connecting accessories to a bedstead comprising a supporting surface, said device comprising:
  • the seating may comprise a profile defined by a single radius of a circle or several arcs of circles or arcs substantially approaching the form of arcs of circles, provided that in all possible embodiments provision is made for a seating adapted to enable said fitting of the pivot pin into the seating and then the oscillation of the first component on the second component.
  • said access opening in the seating is directed upwardly and the central axis of the opening is at right angles to the base surface of the second component lying in a horizontal plane.
  • said pivot pin is inserted radially in the seating through the access opening.
  • the device is characterized in that the first component is radially inserted in the seating from top, according to a first position which is the endmost with respect to all positions corresponding to the several different inclinations of the first component starting from the introduction position as far as the end-of-stroke position.
  • the device is characterized in that said wing and the walls delimiting the seating opening comprise mutually abutting side surfaces designed to constitute end-of-stroke or limit means for the oscillations of said accessory.
  • the excursion of the first component is defined by an angle of predetermined aperture between the introduction and end-of-stroke positions, said angle being included between 90° and 40°.
  • the device is characterized in that said wing form an angle of predetermined width with said plate.
  • the device is characterized in that the angle between said wing and plate is included between 45° and 70°.
  • a further feature of the device is represented by the fact that the first component maintains each of the inclined positions by means of a thrust mechanism having one end associated with the bedstead and provided with an adjustable extension.
  • the cross section of the pivot pin has a substantially circular profile the diameter of which is substantially equal to the diameter of the seating and is broke by at least one substantially rectilinear portion in order to establish the minimum dimensions; in greater detail the cross section of the pivot pin may exhibit two symmetrically opposite substantially rectilinear portions.
  • pivot pin at a circular portion of its transverse profile is rigidly connected to an anchoring plate connected to the first component. This connection is preferably executed close to the rectilinear portion.
  • the pivot pin is integral with one end of a connecting wing extending obliquely to the anchoring plate.
  • the wing defines an acute angle with the plate, the aperture of which is substantially included between 50° and 60° and is for example 55°.
  • the first component consists of an accessory element and the second component consists of a bedstead.
  • the engagement element is carried by an extruded section member associated with the bedstead and disposed transversely;
  • the accessory element in turn, is comprised of an adjustable reclining end portion of the spring support structure.
  • the rectilinear portion of the pivot pin in cross section is substantially parallel to a plane defined by the adjustable end portion so that said end portion operates between one limit position in which it is substantially oriented in a vertical direction and a second limit position in which the adjustable end portion is substantially horizontal.
  • the adjustable end portion is connected to the main bedframe by two coaxial pivot pills engaging in a single seating formed along the extruded section member associated with the bedstead.
  • the seating exhibits a longitudinal flaring at the inlet which is adapted to facilitate the pivot insertion.
  • the pivot and engagement elements have different surface hardnesses and in particular the surface hardness of the engagement element is greater than that of the pivot pin.
  • a device removably connecting accessory elements to a bedstead 2 in accordance with the present invention has been generally denoted by 1.
  • the device 1 is associated with a conventional bedstead 2 only partly shown as not of importance to the ends of the invention.
  • This bedstead 2 widely described in the Italian patent application MI92A 001160 filed on same date in the name of the same applicant, comprises a pair of longitudinal members 3, only one of which is partly shown, with which a spring support structure 4 comprised of a plurality of staves 5 preferably made of wood, is associated, said staves being connected at their ends to the bedstead along appropriate grooves 3' provided in the longitudinal members 3 and being disposed transversely side by side.
  • the device 1 comprises at least one pivot pin 6 rigidly carried by one accessory component that, in the example shown, consists of an adjustable reclining end portion 7 of the spring support structure 4.
  • the adjustable end portion 7 carries at its ends two coaxial pivot pins 6 which are symmetrically disposed.
  • Each pivot pin 6 is operatively engaged, as better clarified in the following, in a seating 8 formed in an engagement element 9 integral with a second component of the bed.
  • the second component is defined by an extruded section member 10, made of aluminium or alloys thereof for example, transversely fastened to the bedstead 2 and incorporating said engagement element 9 so that the seating 8 extends throughout the section member length.
  • Said section member 10 which in turn is the object of the Italian copending patent application MI92A 001158 in the name of the same applicant, is also adapted to the fastening, among other things, of bedposts 11, only one of which, of tubular form, is partly shown.
  • the bedpost, through a screw and nut assembly 11' is associated with a grooved seating 12' formed in the section member 10.
  • the adjustable end portion 7 is also linked to the bedstead 2 by a regulation kinematic mechanism consisting of a strut of adjustable length which is not further described in detail or shown, as known per se and conventional.
  • the above strut can have one extremity associated with the portion 7 for example by inserting a pin in an elongated hole of said portion, and the opposite extremity associated with a rectilinear bar comprising a toothed system fixedly associated with the section member 10 or part of the frame; in this mechanism the strut is provided to be hinged at an intermediate position of its extension with a crosspiece in turn connected at its free end to a toothed element meshing with the toothing of the rectilinear bar.
  • the inclination of the adjustable end portion 7 takes place in register with the movement of the toothed element on the bar toothing.
  • lever means may be provided which are commonly used in the furniture field for tilting a chair back, for example.
  • each pivot pin 6 for example has a substantially elliptical cross section defining minimum dimensions "d” and maximum dimensions "D".
  • the seating 8 also exhibits a circular profile the diameter "D'" of which is substantially equal to the maximum dimensions "D” and is broken by an access opening 14 which is preferably turned upwardly and the width "d'" of which is substantially equal to the minimum dimensions "d”.
  • each pivot pin 6 can be inserted in the seating 8 from top to bottom through the access opening 14 according to a vertical orientation and be subsequently rotated about its own axis so as to engage the adjustable end portion 7 to the bedstead 2 with possibility of movement from the introduction position as far as the end-of-stroke position.
  • the operation involving the insertion of the pivot pin 6 in the seating 8 is made easier by the fact that the seating 8 is provided at the access opening 14 with at least one longitudinal flaring 15.
  • a flaring 15 defines an angle the aperture of which substantially corresponds to that of the central angle defined by the access opening on the circular profile of the seating.
  • Said central angle can be for example in the range of 56° to 156° and in particular between 70° and 120°.
  • the transverse section of the pivot pin 6 exhibits a substantially circular profile, the diameter of which substantially corresponds to the maximum dimensions "D" and therefore to the diameter of seating "D'", broken by at least one secant rectilinear portion 16a.
  • the circular profile is broken by a pair of symmetrically opposite and parallel rectilinear portions 16a defining the minimum dimensions "d" according to a direction perpendicular to the rectilinear portions.
  • the pivot pin 6 thus made can therefore be inserted in the access opening 14 and at the same time it exhibits a pair of circular portions 16b the bending of which substantially corresponds to that of the seating.
  • Each of said circular portions 16b defines, together with the seating 8, a corresponding contact surface of important width, capable of causing an advantageously distribution of loads, which results in an important reduction of the wear due to rubbings produced by the pivot pill within the seating 8, in addition to making the pivot pill rotation easier.
  • the engagement element 9 has a surface hardness different from that of each pivot pin 6; in greater detail in the example described the surface hardness of the engagement element 9 is higher than that of the pivot pins 6 so that the possible wear due to rubbing can occur only on the pivot pins.
  • Each pivot pin 6 is also connected, at one of the circular portions 16a, to a wing 17 for connection with an anchoring plate 18 removably fastened to the adjustable end portion 7, by means of threaded elements 18a, for example.
  • the wing 17 performs several functions.
  • One function is that of adapting the height of the adjustable portion 7 comprising staves 5' to the plane in which the fixed staves 5 forming the spring support structure are disposed.
  • a predetermined length of the wing 17 enables the obtention, for any position of the adjustable portion 7, of an overall surface capable of supporting the user.
  • the wing 17 can also perform the function of determining the stop means for the oscillation of the adjustable portion 7. Said stop means is obtained in combination with the walls of the opening 14 provided in the seating 8.
  • the opposite sides 17' of the wing 17 and the flared surfaces 15 of the opening 14 are used.
  • the adjustable portion 7 is introduced radially from top into the central opening of the seating 8 defined by a central axis of symmetry x-x which is perpendicular to the horizontal plane of the section member 10.
  • the first component due to its introduction into the seating, takes a first radial position also constituting the only withdrawal position.
  • This first position of the first component is the endmost position relative to all the other inclined positions with respect to the section member 10.
  • the opposite sides of the wing 17 are in abutment against at least one point of the flarings 15 in the seating 8.
  • the excursion angle of the wing 17 has a predetermined aperture between two limit values.
  • the optimal solution has been identified by an excursion angle in the range of 90° to 40°.
  • the end-of-stroke position of the adjustable portion 7 can correspond to a horizontal arrangement in which the end of portion 7 rests on stop points (not shown) of the section member 10 or in general on points of the bedstead.
  • a radial spoke (not shown) may be provided which projects from the centre of the pivot pin 6 and is designed to come in abutment on appropriate stop surfaces of the section member 10 so as to set the end-of-stroke positions of the adjustable portion 7, irrespective of the stops consisting of flarings 15.
  • the wing 17 forms a predetermined angle with the plate 18. Preferably said angle is included between 45° and 70°.
  • the angle "b" between the wing 17 and plate 18 is 55° and the rotation front the introduction position to the position setting the portion 7 in a horizontal arrangement is 70°. According to another embodiment, the angle between the wing 17 and plate 18 is 90° and the rotation of the portion 7 between the horizontal arrangement and the introduction position is 45°.
  • the angle "b" between the wing 17 and plate 18 is 70° and the rotation between the limit positions is 40°.
  • angle "b" is 52.5° and the wing excursion between the introduction position and end-of-stroke position is 75°.
  • the wing 17 is 2.5 mm thick and the angle of the access opening delimited between surfaces 15 is 106.8°.
  • positions offering a horizontal arrangement at heights which are different from one another are achieved, depending on the selection of angles "b".
  • a first position of the first component or adjustable portion 7 could be provided corresponding to its radial introduction with respect to the seating 8 and a second and third positions of the adjustable portion 7 rotated in the two ways respectively from the first position, so as to form end-of-stroke configurations of the adjustable portion 7.
  • connection between each pivot pin 6 and the corresponding wing 17 is made adjacent one end of one of the rectilinear portions 16a.
  • portions 16a of the pivot pin could have a curvilinear profile the convexity of which faces away from the plate 18, for example according to an arc of an ellipse or parabola.
  • these curvilinear profiles consist of concentric arcs of circles in which the difference between radii corresponds to the thickness "d" of the pivot pin; in one embodiment these radii are 16.6 and 24 mm respectively and the centre is on the opposite side relative to the kinematic regulation mechanisms of portion 7.
  • Said solution providing curvilinear profiles offers a means capable of favourably counteracting the withdrawal of the first component when it does not occupy the introduction position in the seating 8.
  • Size of the circular profile "D'" included between 6 and 14 mm. Opening size “d'” included between 3 and 12 mm. Central angle defined by the access opening included between 70° and 150°, preferably between 90° and 150°, 110° for example.
  • Length measured between points z, z' included between 6 and 100 mm, 12.6 mm for example.
  • Wing thickness included between 1.5 and 4 mm, 2.5 mm for example.
  • Length between 30 and 200 mm. Width between 30 and 200 mm. Thickness between 2 and 8 mm.
  • the present invention attains important advantages.
  • the device in question has a much simpler structure and advantageously offers easier assembling.
  • the pivot pin 6 is instead radially inserted in the seating 8 through the access opening 14 and therefore need not particular expedients for axial locking.
  • the accessory element consists of the adjustable reclining end portion 7
  • the accessory element consists of the adjustable reclining end portion 7
  • hinging carried out in accordance with the known art envisages the interposition of at least one annular antifriction element generally made of nylon between a generic pivot element and the respective seating.
  • Such antifriction elements by virtue of their nature, can be easily worn out, which gives rise to an undesirable play by the pivot pin in its seating.
  • an unpleasant noise occurs at the hinging and above all the pivot element is subjected to bending and therefore it works in an inappropriate manner, which in the long run may cause its breaking.
  • connection made through the device of the invention need not the use of antifriction elements and therefore does not suffer from the above drawback.
  • the device enables one accessory to be replaced by another, by merely carrying out easy operations involving the radial removal of the first component 7 from the engagement seating 8.
  • the device in question can be used for connecting any accessory element to the bedstead, which element may also have a different typology than the one previously described.
  • the access opening 14 of the seating 8 could start on the front portion of the section member 10 thereby offering greater excursion angles to the wing 17 as compared with those mentioned in connection with the opening of Figs. 1 and 2.
  • the wing 17 could be inclined in such a way as to form an obtuse angle b with the downwardly directed plate surface, instead of an acute angle as shown in the figures.
