Description

The invention relates to sealing door openings with sliding wings and can be used to seal various rooms, including vehicles.

Known cassette-type sliding doors containing one or two leaves that can move in the same plane along the width of the doorway, and in the open position are located either in cavities formed in the wall of the object, for example, in the wall of an electric train car (see the website http: / /electri4ka.com.html> Electric trains> Electric trains ER2 and ER2R> Car body (or http://electri4ka.com/er2r/er2r_12.html) - Fig. 47), or in cassettes installed inside the room wall (see Catalog CASSETON, pp. 10, 11 - casseton.ru website> Technical specifications> Documentation). The seal of the above-mentioned doors of the car of the electric train around the perimeter of the doorway is missing. In the interior doors, brush seals are used, which are installed on the wall along the height of the door, at the entrance to the cassette, on surfaces facing the plane of the sash, but they do not provide heat and sound insulation.

Known sliding door of the vehicle, which contains one or two leaves, moving in the same plane across the width of the door outside the vehicle wall (see European patent EP 1789300 according to class IPC B61D 19/02). To seal the door on the wall of the vehicle around the doorway and around the perimeter of the wings, there are made sealing surfaces located at an angle to the longitudinal plane of the door, and flexible elastic seals are installed on the wings. The left and right parts of the sealing surfaces, both above and below the door, are located at an obtuse angle to each other, which allows simultaneous combination of all the corresponding sealing surfaces around the doorway at the end of the movement of the leaves when they are closed. This requires the presence of additional space at the top and bottom both on the wall and on the door leaf. In addition, the described construction has a developed structure in the transverse plane of the door, and elastic door seals are not available for visual inspection and quick replacement.

Known sliding door containing a sash for closing the doorway in the wall and sealed surfaces located on the wall around the doorway and around the perimeter of the sash. The leaf is installed with the possibility of movement in one longitudinal plane of the door: along the width of the doorway when in the upper position, and along a predetermined path between the upper and lower closed position. In the closed position of the sash, its sealing surfaces abut against the corresponding sealing surfaces of the wall (see GB Patent GB 2015066 according to IPC E05D 15/56, EV 3/46). This door is the closest to the claimed utility model and adopted as a prototype. All sealing surfaces are perpendicular to the longitudinal plane of the door, with the upper and lower sealing surfaces of the sash and walls perpendicular to the side sealing surfaces. The sash moves on suspension rollers mounted on a rail mounted on a wall above the doorway. The trajectory of the sash between the upper and lower position is set by the holes, which are made in certain places of the guide and into which the suspension rollers fall immediately before the door is completely closed. In this design, the door is sealed while simultaneously matching and adjoining all the respective sealing surfaces in the lower closed position of the sash.

The described design provides heat and sound insulation, but not compact enough in the transverse plane of the door. The design is characterized by limited adjustment of the tightened and the possibility of uneven and loose fit of the sealed surfaces to each other if there is no high accuracy of their manufacture and relative position. This is due to the design features of the sealing units and the location of the sealing surfaces relative to each other and relative to the longitudinal plane of the door. In addition, the sealing elements on the upper and trailing edges of the sash are made of wear-resistant elastic material and are not available for quick visual inspection of their condition and replacement.

The problem to which the proposed utility model is directed is to ensure good sealing of the sliding door in conditions of limited space for its layout, as well as to ensure the convenience of technical operation of its sealing units.

To implement the task, the following is proposed.

The sliding door contains at least one leaf for closing the doorway in the wall, sealing elements for sealing the closed door, located on the wall near the doorway and on the leaf, and a threshold. The sash is installed with the possibility of moving in the open position in the longitudinal plane of the door, along the width of the doorway, and with the possibility of lowering to the closed position on the threshold along an inclined path lying in the said plane. In the proposed door on a leaf having a top and a trailing edge, the sealing elements are made along the said edges in the form of sealing protrusions. The sealing elements of the wall, with which the sealing projections of the sash are combined, are made in the form of elastic seals installed at the edges of the doorway, and the sealing protrusions of the sash are made to fit to the corresponding mentioned elastic seals and can move along their surfaces when the sash moves along an inclined path.

The proposed implementation and the location of the sealing elements of the wall and the sash allows for a more uniform and tight fit of all compatible sealing surfaces along the perimeter of the sash and around the perimeter of the doorway of the wall and to ensure a compact design of the door in the transverse plane compared to the prototype. In addition, unlike the prototype, the proposed installation of elastic seals on the wall provides the convenience of their technical operation due to free access to them for visual inspection and quick replacement. All this also provides good sealing of cassette-type sliding doors, which have a compact design in the transverse plane. The sliding door may contain several flaps with the proposed implementation of sealing elements designed to seal the doors at the upper and rear edges of the flaps.

The proposed sliding door is illustrated by drawings.

The door contains a leaf 1, mounted with the possibility of movement in the longitudinal plane of the door on the carriage 2 along a linear guide 3, fixed in the wall 4 (Fig. 1-8). The leaf 1 is connected to the carriage 2 by a parallelogram mechanism 5 formed by levers 6, which are mounted in hinges 7 mounted on the sash 1 and connected to the hinges 8 located on the carriage 2 (Figs. 1, 4, 7). A roller 9 is mounted on the leaf 1, which moves in the groove 10, which is rigidly connected with the wall 4. The groove 10 has a main section 11 located along the width of the doorway, and a section 12 that defines the inclined path of the leaf 1 between its upper and lower positions in one the longitudinal plane of the door. The leaf 1 is returned from the lower position shown by the dotted line in FIG. 1, in the upper position is a shear force across the width of the door. The door may contain a second sash 1 ′ with a similar movement mechanism, ensuring its movement in the same plane with the first sash 1 and closing the sash 1 in the closed position (Fig. 11, 12, 13).

The door contains a leaf 1, mounted with the possibility of movement in the longitudinal plane of the door on the carriage 2 along a linear guide 3, fixed in the wall 4 (Fig. 1-8). The leaf 1 is connected to the carriage 2 by a parallelogram mechanism 5 formed by levers 6, which are mounted in hinges 7 mounted on the sash 1 and connected to the hinges 8 located on the carriage 2 (Figs. 1, 4, 7). A roller 9 is mounted on the leaf 1, which moves in the groove 10, which is rigidly connected with the wall 4. The groove 10 has a main section 11 located along the width of the doorway, and a section 12 that defines the inclined path of the leaf 1 between its upper and lower positions in one the longitudinal plane of the door. The leaf 1 is returned from the lower position shown by the dotted line in FIG. 1, in the upper position is a shear force across the width of the door. The door may contain a second sash 1 ′ with a similar movement mechanism, ensuring its movement in the same plane with the sash 1 and the closing of the sash 1, 1 ′ in the closed position (Fig. 11, 12).

At the end 13 of wall 4, a flexible elastic seal 14 (Fig. 3, 6) is installed with a sealing surface 14 ′ (Fig. 6) to seal the sash 1 along the trailing edge 15 (Fig. 1, 3), and above the doorway, along it width, at the end 16 of the wall 4 is installed a flexible elastic seal 17 with a sealing surface 17 ′ (Fig. 4, 7). On the casement 1 along its trailing edge 15, a sealing protrusion 18 (Fig. 3, 6) is made for alignment with the elastic seal 14, and along the upper edge 19 (Fig. 1) a similar protrusion 20 is made for alignment with the elastic seal 17 (Fig. 4 , 7).

A seal 21 is installed along the lower edge of the sash 1 to seal the door threshold 22 (Figs. 5, 8). A sealing element 24 is installed along the leading edge 23 of the leaf 1 (Fig. 1) (Fig. 3, 6), opposite which a sealing element 25 ′ is located at the end 25 of the wall 4 for alignment with the sealing element 24 (Fig. 3, 6). On the threshold 22, guide rollers 26 are installed, located on both sides of the longitudinal plane q of the sash 1 and are in mechanical interaction with the guide tracks 27 (Fig. 3, 6), mounted on the sash 1.

The leaf 1 can be installed inside the wall 4, consisting of two parts 4 ′, 4 ″, for movement in the space between them (Fig. 9). Then the sealing elements 14, 17, 18, 20 can be located both on one side of the longitudinal plane q of the sash 1 (not shown), and on both sides of the q plane (Fig. 9, 10). In the latter embodiment (Fig. 9, 10), a more complete door seal is achieved.

In the double-leaf door (Fig. 11), the seal of the second sash 1 ′ in the doorway is similar to the seal of the sash 1 described above, only along the front edge of the sash 1 ′ there is a sealing element 24 ′ with a mating part for alignment with the sealing element 24 of the sash 1 (Fig. 12 ) Also, the flaps 1, 1 ′ can be installed inside the wall 4 between its parts 4 ′, 4 ″ (Fig. 13), and the sealing elements 14, 17, 18, 20 can be located on both sides of the longitudinal planes q, q ′ valves 1, 1 ′ (Fig. 13) or on one side of the planes q, q ′ (not shown).

When the door is open, the sash 1 is in the upper position, the elastic seals 14, 17 are not in contact with the sealing protrusions 18, 20 of the sash 1 (Fig. 6, 7), the seal 21 of the sash 1 is not in contact with the threshold 22 (Fig. 8). To close the door, the sash 1, in the upper position, is moved along the width of the doorway in the direction indicated by arrow b (Fig. 1). In this case, the carriage 2 with the parallelogram mechanism 5 slides along the guide 3, the roller 9 rolls along the section 11 of the groove 10 to the section 12 (Fig. 1, 7), and the shutter 1, being at some distance from the ends of the elastic seals 14, 17 and from the threshold 22 moves freely between them. With the further movement of the carriage 2 along the guide 3, the roller 9 rolls onto the section 12 of the trough 10 (Fig. 1), the levers 6 of the parallelogram mechanism 5 rotate around the hinges 7, 8 and the sash 1 moves along an inclined path, descending to the lower position (Fig. 2 , 4, 5, 11). When the leaf moves along an inclined path, the sealing protrusions 18, 20 of the leaf 1 (Figs. 3, 4) move respectively along the surfaces 14 ′, 17 ′ of the flexible elastic gaskets 14, 17 until they fit completely together along the width and height of the door. At the end of the movement, the sash 1 is lowered to the threshold 22. In this case, the sealing element 24 is aligned with the sealing element 25 of the wall and fits snugly against it, the sealing protrusions 18, 20 are adjacent to the elastic seals 14, 17 (Fig. 3, 4, 9, 10) and the seal 21 is simultaneously pressed against the threshold 22 (Fig. 5). At a double-leaf door, the sash 1 ′ moves towards the sash 1 similarly to the last. The flaps 1, 1 ′ at the end of the movement are closed and simultaneously lowered to the threshold 22, while the sealing elements 24, 24 ′ on the front edges of the flaps 1, 1 ′ fit snugly against each other (Figs. 11, 12, 13). By moving the protrusion 18 along the surface 14 ′ of the elastic seal 14 and the protrusion 20 along the surface 17 ′ of the elastic seal 17 in the longitudinal plane of the door, a more snug fit between the protrusions 18, 20 and the corresponding elastic seals 14, 17, as well as all other corresponding door sealing elements . The proposed implementation of the sealing elements 14, 17, 18, 20 for sealing the door along the upper and trailing edges 19, 15 of the leaves 1, 1 ′ allows the use of such sealing elements in the doors of cassette type having a compact design in the transverse plane (Fig. 9, 10, 13). Since the elastic seals 14, 17 are located on the wall 4 along the edges of the doorway, they are available for quick visual inspection and timely replacement.

Thus, due to the improvement of the door sealing nodes along the upper and trailing edges of the leaves, a good fit of all sealing surfaces of the wall and leaves is achieved, which provides heat and noise insulation of the room in conditions of limited space for door layout, as well as the convenience of technical operation of elastic gaskets.
