DETAILED EXHIBITION OF REALIZATION MODES

An example of a sliding door system 1 according to the present invention has been shown in the appended Figures 1-3. It can be seen that said door system 1 can comprise a door body 2 concealable in a housing cavity 91 (see figures 6 and 7) arranged in an enclosure 9. The door body 2 may be made of any suitable material, although exemplary may be metallic or of wood. As for the enclosure 9 may be for example a partition or in general a wall or wall capable of closing or limiting a space.

In the figures it can be seen that the door body 2 can comprise: a frame 3, at least one side structure 4 linked to the frame 3, and a linking mechanism 5 arranged between the frame 3 and the side structure 4. In figure 4 an example of a door body 2 with a single side structure 4 linked to the frame 3 is shown. Figures 1 3 and 5 show examples of door bodies 2 comprising a pair of side structures 4 arranged on both sides of the frame 3, so that a walled configuration can be defined. In other examples not shown, the door body 2 may include even more lateral structures 4.

The frame 3 and the side structure 4 can be configured in the form of a frame, for example metal, synthetic, wood, etc.

In some examples, at least one of the side structure 4 and the frame 3 can have a laminar configuration. The attached figures show examples in which both have said laminar configuration. The side structure 4 may comprise a panel-like covering 42. The liner 42 may be attached to the side structure 4 by mechanical or chemical bonding with adhesives.

In another example, the side structure 4 and / or the frame 3 can be configured as panels or panels of the door body 2. Thus, the door body 2 can comprise a frame 3 and at least one side structure 4 configured as a ceiling light.

The linking mechanism 5 can be configured such that the frame 3 and the lateral structure (s) 4 are able to move relatively close to each other, so that the thickness of the door body 2 is variable. Figures 9, 13, 17, 21 illustrate examples of door bodies 2 arranged in a closed position, ie, sealing an opening 92 or the like disposed in the enclosure 9. In said position the side structure 4 and the frame 3 they would be farther apart than in the open position as shown in figures 10, 14, 18, 22, where they would be closer to each other. Its operation will be described later.

According to an example, the sliding door system 1 can additionally comprise a guidance system 6 at least for the lateral structure 4, in which the guidance system 6 can be configured in such a way that the displacement of the lateral structure is directed 4 with respect to at least one of: the frame 3 and the enclosure 9.

The guiding system 6 may comprise a first groove 61 in the shape of "L", and may further comprise a first projection 41 capable of traveling along the first groove 61, said first projection 41 may be arranged on the side structure 4 as you can see in figures 1-3, 19, 21, 22.

The first projection 41 can be configured as a roller or the like designed to reduce friction with the first groove 61.

In another example, the guiding system 6 may comprise a second elongated groove 62, and may further comprise a second projection 31 capable of traveling along the second groove 62; said second projection 31 may be arranged in the frame 3 as can be seen in figures 1-3, 19, 21, 22.

The second projection 31 can be configured as a suspension element of the door body 2. In an example the second projection 31 can comprise an extended height nut 32 with through threaded hole, in which the lower end (in a condition of use) a threaded rod 33 of the frame 3 can be screwed, and at the upper end (in a condition of use) another threaded rod 34 is screwed which is suspended from the guiding system 6. The configuration of the extended height nut 32 is such that the height and inclination of the door body 2 can be varied with respect to the floor on which it is placed. In any case, this union could be done in another way to achieve the same effect.

According to an example, the guidance system 6 may comprise a plate configured as a lintel. This plate can be clearly seen in Figures 6-8, 19-22; said plate may comprise at least one groove 61, 62, and in some cases it will comprise a pair of first grooves 61 on both sides of a second groove 62. This arrangement can respond to the sandwich-like configuration of the frame 3 and the side structures 4. In another example the grooves 61, 62 may have rounded vertices 66 ; this characteristic can be clearly represented in figure 8.

In other examples, such as those shown in FIGS. 11-18, the guidance system 6 may comprise a shoulder 63 arranged in the side structure 4 as a rail. In a complementary manner, the guiding system 6 may further comprise a third projection 64 positionable in the enclosure 9, so that said third projection 64 may be able to move relative to the flange 63. The concrete position of the third projection 64 may vary depending of each case, but may be positioned so as to allow relative displacement between the third projection 64 and the flange 63. In the illustrated examples of FIGS. 11-14, a pair of third projections 64 for the respective flanges 63 is provided in FIG. each of the flanges 63 of the side structures 4. In the examples of Figures 15-18 there are arranged four third projections 64, namely one pair for each flange 63 of the respective side structures 4

The manner of obtaining a ridge 63 may vary, but in an exemplary case said ridge 63 may be formed as a cutout or recess cut in and along the top side (in a condition of use) of the liner 42 of the side structure 4. These examples are illustrated in Figures 11 and 15 and in the details where the area is enlarged.

In Figures 11-14 it can be seen that the flange 63 may comprise a step-like recess 65. In this way the third projection 64 can be accommodated relatively in the recess 65. Particularly in Figure 13 can be seen how the third projection 64 can be housed in the recess 65 in a closed position.

In Figures 15-18 the flange 63 may comprise a stop 67 at one of its ends, namely the one most distant from the cavity 91. This stop 67 is configured so that it can contact a third projection 64 or the like in one position closed.

When the sliding door system 1 comprises at least one pair of lateral structures 4, the guidance system 6 can be configured so that for example the torque of lateral structures 4 are capable of describing symmetrical trajectories among themselves.

The sliding door system 1 may additionally comprise a sliding system configured for guiding the frame 3 with respect to the receiving cavity 91.

The sliding system can further comprise a sliding shoe 71 which can be positioned, for example, to guide the frame 3 at its base. This sliding shoe 71 can be configured as a guide rail, as shown in FIGS. 1-3.

To facilitate the operation of the present sliding door system 1, the sliding system may comprise a driving device 72. This driving device 72 may comprise any suitable driving element such as an electric motor or the like which allows the door body 2 to be driven between a open position and closed one.

If the sliding door system 1 comprises a driving device 72, it can be connected to at least the second projection 31, making it move with respect to the corresponding second groove 62. The driving device 72 may comprise an electric motor such as those used to drive conventional sliding doors.

In FIGS. 1-2 an example of the present sliding door system 1 comprising a supporting structure 8 is shown; this supporting structure 8 can comprise columns and a crossbar arranged as a portal. The supporting structure 8 can support different components of the sliding door system 1, for example the plate of the guiding system 6 or the driving device 72. In this case the plate of the guiding system 6 can have a suitable shape as shown in FIGS. 1-3, which may comprise a "U" profile capable of being connected to the supporting structure 8, for example fixed to the crosspiece, The guide system 6 may be linked to the crossbar in another alternative way, using screws or any other type of linking.

According to an example, the guidance system 6 may comprise a plate configured as a lintel. This plate can be clearly seen in Figures 6-8, 19-22; said plate may comprise at least one groove 61, 62, and in some cases will comprise a pair of first grooves 61 on both sides of a second groove 62.

The linking mechanism 5 may comprise at least one connecting arm 51 rotatably connected to the frame 3 and the lateral structure 4. In figures 1-3 the connecting arm 51 has a triangular configuration although it is obvious that it may present another type of adequate configuration for each case. A common anchor shaft can be used for a link arm 51 of a side structure 4 and another link arm 51 intended to be joined with another side structure 4 linked to the frame 3. However each link arm 51 can have its respective portion 52, 53 of the common anchor axle for both link arms 51.

One way to achieve the swivel connection between the connecting arm 51 and the frame 3 or between the connecting arm 51 and the lateral structure 4, can be to provide a hinge-type connection as can be seen in figures 1-3.

The number of linking mechanisms 5 may vary according to the particular needs of each case; by way of example illustrated in Figures 1-3 a possible solution comprises four connecting arms 51 between each side structure 4 and the frame 3.

The connecting arm 51 can be arranged obliquely with respect to the frame 3 and the lateral structure 4 seen in plan and in an expanded condition, as seen for example in figures 4 and 5.

The connecting arm 51 can be arranged perpendicular to the frame 3 and to the lateral structure 4 seen in plan and in an expanded condition.

When the sliding door system 1 can comprise a second groove 62, the connecting arm 51 can be arranged such that it can link the first projection 41 of each side structure 4 and the second projection 31 of the frame 3, as for example illustrated in FIG. Figures 21 and 22.

In Figures 4, 5, 9, 10, 13, 14, 17, 18, 21, 22 it is illustrated that the linking mechanism 5 may comprise at least one pair of link arms 51 arranged in such a way as to define a configuration of articulated parallelogram between the frame 3 and the lateral structure 4 seen in plan. In figures 4 and 5 one can also see the trajectory 61A that a first projection 41 can follow between the open and the closed position. Figure 4 shows a scheme of linking mechanism 5 between a single lateral structure 4 and a frame 3 and in figure 5 the same scheme has been represented but adapted to the case in which it comprises a pair of lateral structures 4, conforming in both cases the articulated parallelogram.

As shown in FIGS. 13 and 14, the door body 2 may comprise an elastic element 21 disposed between the side structures 4 or between the frame 3 and the side structure 4. The elastic element 21 may be configured so as to act on the relative approaching / distancing between the frame 3 and the side structure 4, for example, may be arranged so as to exert a reaction force against the compression exerted through the side structure 4 during its actuation. In the illustrated examples there may be multiple elastic elements 21, and they may be arranged, for example, close to the linking mechanisms 5 so that their function is optimized. If the elastic element 21 is arranged between two facing lateral structures 4, said elastic element 21 can exert a separating force between both, so that it acts in the relative approach / distance between the frame 3 and each of the side structures 4 and between both lateral structures 4.

The side structure 4 may comprise a strip (not shown) on at least one of its perimetric edges to improve the closing of the door body 2. In other examples not shown, the side structure 4 may additionally comprise at least one elastic joint or gasket. sealing, arranged such that in the expanded condition said elastic joint can contact at least partially with the enclosure 9 in the vicinity of the opening 92. In this way an optimum tightness can be achieved relatively between the door body 2 and the enclosure 9, sealing not achieved in the sliding doors of the state of the art. In an example in which the door body 2 comprises at least two side structures 4 (respectively on both sides of the frame 3) with respective elastic joints, an insulation greater than that of a conventional swing door can be achieved.

In figures 6, 7, 11, 12, 15, 16, 19, 20 there is shown a spacer assembly 100 characterized in that it comprises a sliding door system 1 as described above and an enclosure 9. The enclosure 9 can comprise the opening 92 capable of being sealed with the sliding door system 1. The separator assembly 100 can be configured in such a way that in an expanded condition or closed position the door body 2 can be flush with at least one facing 93 of the enclosure 9 as seen in figures 6, 11, 13, 15, 17, 19, 21. According to other examples, the separator assembly 100 can be configured such that in an expanded condition or closed position the body of door 2 can be flush simultaneously with two walls 93 of the enclosure 9.

Next, the operation of the invention for a manual operation and another automatic or robotic operation will be described. In the first case starting from a closed or extended position of the door body 2 as represented by figures 9, 21, in which the door body 2 can be flush with the facing 93 of the enclosure 9, the user must only press a lateral structure 4 against the frame 3 so that the first projection 41 moves along the path 61A, with respect to its first groove 61 in the shape of "L." During this described displacement, the lateral structure 4 approaches the frame 3, a narrowing in the thickness of the door body 2 occurs, so that the door body 2 can be accommodated in the housing cavity 91. The first projection 41 has moved along the short length of the "L". This short section can be directed towards the frame 3, so as to allow the relative distance between the frame 3 and the lateral structure 4.

When the connecting arm 51 is arranged obliquely with respect to the frame 3 and the side structure 4 seen in plan and in an expanded condition, it is allowed that by pressing one of the lateral structures 4 and bringing it relatively close to the frame 3, it starts to move along the plane parallel to the enclosure 9, and can drag the other side structure 4 (if any), both side structures 4 being able to be linked to the frame 3.

Following the actuation of the door body 2, then the first projection 41 continues along the long section of the "L" at the same time that the second projection 31 moves relative to its second elongated groove 62. In this way the body of door 2 is gradually lodged in the housing cavity 91 until it is hidden. The long section of the "L" would be comprised in a plane parallel to the enclosure 9 and directed towards the housing cavity 91.

To close and return to the expanded position from the closed position the user will only have to "pull" the door body 2 in a direction parallel to the enclosure 9 and in the direction of the opening 92, so that the mechanism reproduces the operation but vice versa until again the door body 2 is flush with one or more of the faces symmetrically with respect to the frame 3.

In other constructions, the sliding door system 1 may comprise an automatic or robotic actuator in which it does not have to exert any pressure or effort for actuating the door body 2. When the actuator is automatic, then the connecting arm 51 can to be arranged perpendicular to the frame 3 and to the side structure 4 seen in plan and in an expanded condition. In this case, the sliding door system 1 can have motor devices (not shown) that make it possible to assist the relative approach between the lateral structure 4 and the frame 3. The connecting arm 51 can also be arranged obliquely as in the manual case described before.

In the cases in which the sliding door system 1 does not comprise first or second grooves 61, 62, starting from a closed or extended position of the door body 2 as illustrated in figures 13, 17, the flange comes into play 63 and the third projection 64, which may vary their number depending on the needs. The door body 2 also reaches the collected or closed position inside the housing cavity 91. The user does not have to modify the way of acting despite the difference in construction. In the cases of FIGS. 13 and 17, a path of the third projection 64 in the form of an "L" in relation to the flange 63, similar to that described for the previous cases, is also described. The flange 63 would form the long section of the "L" and the recess 65 or the stop 67 would form the short section of the "L". This similarity can be clearly seen between figures 9, 21 on one side and 13, 17 on the other.

With respect to Figures 13, 14, starting from the expanded or closed position of Figure 13, the third projection 64 may be housed in the recess 65. Then, with the approximation of the lateral structure 4 relative to the frame 3, the third projection 64 moves relatively away from the recess 65 and can be aligned with the rim 63, in this way the door body 2 can advance towards the housing cavity 91 with a reduced thickness as shown in figure 14. At the time of closing the door the same procedure would be followed but in reverse.

As for FIGS. 17, 18, the expanded or closed position of FIG. 17 is assumed. In this example, at least one pair of third projections 64 is disposed in the enclosure 9 one on each side of the opening 92. Fig. 17 it can be seen that the stop 67 can make contact with the third projection 64 closest to it. At the moment when the lateral structure 4 and the frame 3 are relatively close, the third projection 64 farther away from the stop 67 in the expanded position can be aligned with the flange 63 and the door body 2 moves towards the cavity housing 91 due to the narrowing of the thickness of the door body 2. At the time of closing the door, the same procedure would be followed, but in an inverse manner.

Although only certain embodiments and particular examples of the invention have been described here, the skilled person will understand that other alternative embodiments and / or uses of the invention are possible, as well as obvious modifications and equivalent elements. In addition, the present invention encompasses all possible combinations of the specific embodiments that have been described. Numerical signs relating to the drawings and placed in parentheses in a claim are only to try to increase the understanding of the claim, and should not be interpreted as limiting the scope of protection of the claim. The scope of the present invention should not be limited to specific embodiments, but should be determined only by an appropriate reading of the appended claims.
