Definitions

  • the present invention relates to an opening mechanism for sliding doors, in particular of cupboards.
  • the first systems which are used in particular with doors which, when closed, are coplanar, are strong and simple to build, but require a considerable amount of free space in front of the cupboard, to allow opening of the doors.
  • the second systems can be divided into sliding opening systems with doors arranged over each other and sliding opening systems with coplanar doors.
  • Another known system which is similar to the previous system, comprises two doors which are each supported by oscillating arms on four carriages, two of which are slidable on the top and on the bottom of the cupboard along a guide fixed to the cupboard and extending along the whole front side thereof.
  • the oscillating arms may extend with respect to the carriage, thus causing the depth-wise displacement of one door with respect to the other one.
  • the displaced door is pushed edgewise with consequent travel of the four carriages inside the guide from one end to the other one.
  • the construction with the four carriages is complicated and costly.
  • the displacement operation is often difficult to perform because of the vibrations affecting the door, the difficulty in correct alignment of the guides and the imperfect synchronization between the upper and lower guides (or carriages).
  • Another major disadvantage of the known systems is that only two doors may be arranged over each other such that the number of doors which may be open simultaneously is limited.
  • the main object of the present invention is therefore to provide an opening mechanism for sliding doors which does not have these drawbacks.
  • an opening mechanism for each of a plurality of doors of a furniture unit arranged alongside each other in the closed position and provided with sliding travel means, comprising:
  • Figs. 1 and 2 10 denotes a cupboard which has two identical sliding doors 12, the closed one of which is denoted in Fig. 1 by 12C ("C" standing for closed) so as to distinguish it from the other door when it is open, the latter being indicated by 12A, and which incorporates a mechanism 11 according to the invention by means of which one of the two doors 12 can be extracted and arranged over the other door (Fig. 1).
  • the module 11a comprises - see Fig. 5 - five elements: a support element 20a, a horizontally oscillating element 40a, two identical coupling elements 60a, 70a and a fixed containing element 90a. These elements are fixed at the top and at the bottom of the cupboard 10 and extend substantially over the entire width of a door, having moreover a constant cross-section.
  • the set of elements 40a, 60a, 70a, 90a forms a frame which is extractable from the cupboard with a horizontal movement, useful for positioning the door 12A so that it is displaced with respect to the adjacent door 12C in a direction perpendicular its plane of lie.
  • the door 12 is supported and fixed to the support element 20a which at the top has a horizontal groove 22a with at the bottom 24a thereof a concavity 26a, and an end with two vertical flanges 28a, 30a to which a roller wheel 32a with an axis of rotation X perpendicular to the door 12 is rotatably fixed.
  • the two flanges 28a, 30a are contained in a support guide 34a (for example a groove) of the coupling element 40a, which is geometrically identical in terms of its form and its bottom 36a to the groove 22a.
  • the coupling element 40a is composed of three parts:
  • These two sets of teeth 51a, 52a are engaged, respectively, by the two coupling elements 60a and 70a which are hollow cylinders with respective sets of teeth 62a, 72a on their surface.
  • the two coupling elements 60a and 70a engage respectively also with two sets of horizontal teeth 92a, 94a provided on two parallel and horizontal surfaces 96a, 98a of the containing element 90a.
  • the latter has the form of a U, with the surfaces 96a, 98a forming the two parallel arms of the U.
  • the surface 98a, below the surface 96a is longer and its smooth portion 100a, adjacent to the teeth 94a, forms a supporting and travel surface which is delimited by a stop 101a for the roller wheel 46a.
  • the two modules 11a, 11b of the mechanism 11 are joined together and synchronized by means of a vertical bar 110, the ends of which are provided with two eyelets 112, 114 having respective internal teeth 116, 118.
  • the two coupling elements which are closest to one another, 70a, 70b, are inserted, with a corresponding section, into the eyelets 112, 114 and mesh with the internal teeth 116, 118 of the latter. Therefore, an anti-clockwise rotation of the profile 70a results in raising of the bar 110 and a corresponding rotation of the profile 70b in the same direction and in a synchronized manner (the bar 110 therefore acts as a mechanical transmission system).
  • the bar 110 may be engaged with the profiles 70a, 70b at their ends, also passing through suitable openings (and/or shapes) in the profiled parts.
  • Fig. 6 shows the same mechanism 11 after the door 12A has been extracted and positioned over the closed door 12C (in the drawings the opening movement corresponds to a movement to the left - see arrow F in Fig. 5). Comparing Fig. 5 with Fig. 6 the operating principle of the mechanism 11 is self-explaining. Extraction of the door 12C towards the outside of the cupboard 10 (to the left in Fig. 6) causes the movement of the roller wheels 46a, 46b in the same direction as far as the respective stops 101a, 101b on the surfaces 100a, 100b which is accompanied by the travel movement, in the same direction, of the coupling elements 60a, 70a and 60b, 70b on the teeth 92a, 94a and 92b, 94b, respectively.
  • the toothed end parts 50a, 50b also move in the direction F and the bar 110 is raised.
  • the two coupling elements 70a, 70b rotate in an anti-clockwise direction and mesh with the teeth 116, 118 in the eyelets 112, 114 along a toothed arc with a rising motion.
  • the perfectly synchronous movement of the moving parts in the two modules 11a, 11b is ensured by the rod 110 which, forcing the four coupling elements 60a, 70a, 60b, 70b to rotate in synchronism, allows the elements 40a, 40b to move together. This eliminates oscillating movements of the door during the displacement movement.
  • the coupling elements 70a, 70b may mesh with the teeth of a rigid connecting body which may also have a different form, or by means of a chain or belt.
  • the extracted door namely the door which opens, is coupled with the door 12C by means of the flanges 28a, 30a, (28b, 30b) and the roller wheels 32a (32b) which are inserted so as to travel inside the guideway 22a(22b) of the door 12C.
  • the latter also supports the door 12.
  • the invention may thus also be applied to cupboards with more than two doors.
  • the oscillating element 40a (40b) and the two coupling elements 60a, 70a (60a, 70b) to perform a horizontal travel movement with various intermediate stable positions, the position of the extracted door 12 may be displaced (offset) depth-wise into positions which are increasingly distant from the closed door 12C.
  • a first extracted door may be arranged over and coupled with a second adjacent closed door, and the first and second door together may be extracted so as to be arranged over and coupled with a third door, which is closed and adjacent to the second door, and so on.
  • the first door is arranged on the second door and the second door on the third door, which is closed.
  • the first door is then extracted with a displacement equal to about twice that of the second door, in view of the thicknesses of the second and third doors.
  • the method may also be applied to any number of doors, provided that the horizontal travel movement of the oscillating element 40a (40b) is adapted.
  • Another possibility offered by the invention is being able to extract more than one door at a time.
  • a cupboard 200 with four doors 210, 212, 214, 216 as shown in Fig. 8a, it is possible to extract two adjacent doors 210, 212 and then arrange them in front of the other two closed doors 214, 216, respectively - see Fig. 8b.
  • the extracted door 210 has a travel movement which is half the length of the cupboard 200, something which is not possible with the known opening mechanisms.
  • the extracted door may be arranged over an adjacent door, which therefore acts as a support, remaining coupled with the latter.
  • the set of two doors is connected to the cupboard only by means of the sliding coupling means of the supporting door which supports the extracted and laterally displaced door. If this supporting door, in turn, is extracted and displaced, it will be coupled with another door and will transport, together with it, the door which it is supporting.
  • a door may comprise at least one second auxiliary guide parallel to the support guide and offset depth-wise with respect to the latter by an amount equal to a horizontal movement of the frame which is necessary for extraction of the door beyond two or more doors already superimposed to ensure alignment of the at least one second auxiliary guide with a support guide on the frame of the adjacent door already superimposed, producing from the two aligned guides a section along which the coupling means are able to travel, causing the extracted door to be arranged over the (already) superimposed adjacent door.
  • the guide may be constructed in a very simple manner in order to keep to a minimum the components and the costs. If the guide is formed with a groove on the door, the complexity of the mechanism is further reduced and the reliability increased.
