Description

The utility model relates to sliding door mechanisms with roller suspensions of sashes and can be used in various fields of technology, in particular, in passenger vehicles.

There is a need to upgrade cabin sliding doors of different widths in passenger train cars in accordance with the new regulatory requirements for such doors.

Known mechanisms for sliding doors with roller suspensions of the valves containing carriages and wall-mounted bearing guides of a C-shape with upper and lower shelves. The carriages are installed in bearing rails on rollers having a horizontal axis of rotation, and are equipped with fasteners to the door leaf. When the carriage moves, the rollers move along the guides, in contact with either the lower shelf of the guide (see, for example, EPO patent No. 0444378), or with all its walls (EPO patent No. 0596362). The mentioned analogues do not provide for the possibility of fixing the carriages in their extreme positions - with the door open or closed.

Known sliding door mechanisms with similar leaf suspensions, in which the carriages are mounted in a bearing guide on rollers, spring-loaded to the lower and upper shelves of the guide (German application DE 19601287, Fig. 6; RF patent for utility model No. 37512). In these mechanisms, on the carrier rail, in the places of extreme positions of the carriages, grooves are made for fixing one of the carriage rollers. The elastic elements used ensure reliable contact of the carriage rollers with the guide shelves and the fixation of the rollers in the grooves when the shutters are in the open and closed positions. The disadvantages of such mechanisms include the limited ability to adjust the positions of the carriages in the places of their fixation due to the invariable location of the locking grooves.

A known sliding door mechanism with a guide roller in the upper part of the sash and a roller fixing device when the sash is in the open position (see German application for utility model DE 202006008483 U1). The roller is fixed on the leaf, has a vertical axis of rotation and is installed in the guide rail, in contact with its vertical walls. The fixing device has a pressure element, which is made in the form of a spring-loaded ball or bolt with a rounded free end and mounted in a housing fixed to the outside of the guide rail. The shutter is locked in the open position when the pressure element interacts with the circumferential surface of the guide roller, and the pressure element, moving to the roller, passes through the hole in the guide rail. This mechanism, like the previous analogue, does not have the ability to adjust the open position of the sash relative to the pressure element, the location of which is determined by the constant coordinates of the said hole.

A sliding door mechanism is also known, comprising a supporting guide, a carriage for horizontal movement of the sash in the longitudinal plane of the door, a device for fixing the carriage on the supporting guide in the open position of the sash, and a device for fixing the carriage on the supporting guide in the closed position of the sash. The carriage comprises a housing with fasteners to the leaf, on which the rollers are mounted rotatably in the longitudinal plane of the door, and is mounted by rollers on the supporting rail with the possibility of moving along it. The carriage is located inside the profile of the carrier rail. Each carriage fixation device consists of two parts, the first of which is made in the form of a pin located on the carriage body along the carrier rail, and the second is an elastic counterpart that is fixedly mounted on the carrier rail opposite the pin (see www.mfurnitura.com Mechanisms for sliding doors, partitions). When moving the carriage to one of the extreme positions, the pin of the corresponding fixing device enters the mating part and is held in it by friction forces. This mechanism is the closest in technical essence to the proposed utility model and adopted as a prototype. The counterpart of the fixation device is installed with the possibility of mounting adjustment of its position along the length of the carrier rail, which determines the position of the carriage fixation, which makes the mechanism convenient for installation and universal in use for hanging the valves of different sizes. But at the same time, carriage fixation devices are located inside the guide profile and are not available for quick visual inspection and maintenance during operation. In addition, under the influence of vehicle vibration, the frictional forces that hold the carriage with a pin in the counterpart of the locking device will be weakened. Therefore, the considered mechanism is inconvenient for maintenance, as well as ineffective in the doors of passenger vehicles due to unreliable fixation of the carriage on the carrier rail.

The problem to which the proposed utility model is directed is to create a sliding door mechanism with a manual drive, convenient for installation, maintenance, and providing high efficiency of the mechanism in conditions of operation in passenger transport.

To solve this problem, the following is proposed.

The sliding door mechanism comprises a supporting guide, a carriage for horizontal movement of the sash in the longitudinal plane of the door, a device for fixing the carriage on the supporting guide in the open position of the sash, and a device for fixing the carriage on the supporting guide in the closed position of the sash. The carriage comprises a housing with fasteners to the leaf, on which the rollers are mounted rotatably in the longitudinal plane of the door, and is mounted by rollers on the supporting rail with the possibility of moving along it. Each carriage fixation device consists of two parts, the first of which is located on the carriage body, and the second is mounted on the carrier rail with the possibility of mounting adjustment of the carriage fixation position.

In the proposed mechanism, the locking devices are made with the possibility of elastic fixing of the carriage on the supporting rail, and both parts of the locking devices of the carriage in the open and closed positions of the sash are made with the possibility of quick access to them. Moreover, the second part of each carriage fixation device is mounted on the outer surface of the carrier rail and is displaced in the longitudinal plane of the door vertically relative to the carriage body. In this case, in the carriage fixation device in the open position of the sash, the first part is made in the form of a part having a flat surface with a locking groove located perpendicular to the longitudinal plane of the door and parallel to the direction of movement of the carriage. Its second part contains a stopper with a pressure element spring-loaded to a flat surface with a stopper groove of said part with the possibility of mechanical interaction with them.

The proposed arrangement of fixation devices in the mechanism provides, in comparison with the prototype, not only the open arrangement of their parts, but also the most convenient location for installation, visual inspection and maintenance. In addition, the elastic fixation of the carriage on the carrier rail, which is provided by both fixation devices, and, in particular, the proposed embodiment of the carriage fixation device in the open position of the sash, allows for reliable fixation of the sash under vibration conditions in passenger vehicles due to the constant action of the elastic elements (springs).

The first part of the device for fixing the carriage in the closed position of the sash can be made in the form of a flange mounted on top of the carriage body, and the second part is in the form of a pneumatic cylinder mechanically connected to the flange with a return spring to hold the carriage in the closed position of the sash. This design additionally provides a smooth return of the carriage with the sash from the intermediate position to the closed, as well as reliable fixation of the carriage on the carrier rail in the closed position of the sash under vibration conditions as a result of the compression force of the return spring.

The first part of the device for fixing the carriage in the closed position of the sash can be made in the form of a part having a flat surface with a locking groove located perpendicular to the longitudinal plane of the door and parallel to the direction of movement of the carriage. At the same time, its second part can be made in the form of a stopper with a pressing element spring-loaded to a flat surface with a locking groove of the part with the possibility of mechanical interaction with them, which allows to simplify the design of the mechanism as much as possible.

A part with a locking groove may be located at the top of the carriage body and facing a flat surface with a locking groove up, and the stopper is mounted on a carrier rail above the carriage in a fixed place for its fixation.

A part with a locking groove can also be located at the bottom of the carriage body and facing a flat surface with a locking groove down, and the stopper is mounted on a carrier rail below the carriage in a fixed place for its fixation.

To ensure reliable operation of the fixing device, the part with the locking groove and the pressure member is expediently made with the possibility of smooth mechanical interaction with each other.

The essence of the proposed mechanism is illustrated by drawings.

In FIG. 11 is a view E of FIG. 10.

The sliding door mechanism (Figs. 1, 7, 10) contains a supporting guide 1, a carriage 2 mounted on it with rollers 3 for horizontal movement of the sash 4, a device 5 for fixing the carriage 2 in the open position of the sash 4, and a device 6 for fixing the carriage 2 in the closed position wings 4.

The bearing guide 1 consists of two profiles 7 (Fig. 2, 3) with the upper and lower shelves 8, 9 (Fig. 2) for installing the rollers 3 (Fig. 3) of the carriage 2. The profiles 7 are interconnected by fixing nodes 10 and screws 11 (Fig. 2, 6, 9). In the upper and lower parts of the profiles 7 there are longitudinal grooves 12, 13 for fastening the nodes and parts of the mechanism (Fig. 2, 3, 5, 8).

The carriage 2 contains a housing 14 (Fig. 3-11), on which the rollers 3 are mounted on the horizontal axes 15 (Figs. 3-8, 10) so that when the carriage 2 is moved on the shelves 8, 9 of the profiles 7 of the bearing guide 1, the rollers 3 rotate in the longitudinal plane of the door. The housing 14 of the carriage 2 contains elements 16 (Fig. 1, 3, 4, 7, 10) for fastening the sash 4 with bolts 17 (Fig. 3) and can be of any design. In particular, in FIG. 4, 7, 10, the housing is made of several holders 14 of the rollers 3, rigidly interconnected by rods 14 ′.

The device 5 for fixing the carriage 2 in the open position of the door leaf (Fig. 1, 7, 10) consists of two parts: from the part 18 (Fig. 4, 7, 11) fixed at the top or bottom of the housing 14 of the carriage 2, and the stopper 19 ( Fig. 2, 7, - 10) with a pressure member 20 mounted on a carrier rail 1. Part 18 has a flat surface 21 (Fig. 4, 9, 11) with a locking groove 22. The surface 21 is perpendicular to the longitudinal plane of the door and parallel to the direction the movement of the carriage 2 so that it faces down (Fig. 6) or up (Fig. 9). The stop 19 is fixed outside the bearing guide 1 (Fig. 1, 2, 7-10) with bolts 23 with clamping nuts 24 located in the grooves 13 below the bearing guide 1 (Fig. 2) or in the grooves 12 at the top of the bearing guide (Fig. 8) . When this stopper 19 is installed, respectively, below the carriage 2 (Fig. 1, 6) or above it (Fig. 7-10). As a stopper 19, a spring ball retainer of the KIPP company, with a spring of increased elasticity (http: www.alterv.ru/site.xp/050049054052.html), was selected. The pressing element 20 of the stopper 19 is made in the form of a ball (Fig. 2, 8, 9, 11), which is spring-loaded to the surface 21 with the locking groove 22 of the part 18 (Fig. 6, 9). On the part 18, for smooth mechanical interaction with the pressure element 20, a surface 25 is made (Fig. 6, 9), forming an obtuse angle with the surface 21, and the locking groove 22 has a v-shape and depth, which releases the carriage 2 from being fixed by pressure elemental 20 when manually moving the sash 4 with the application of permissible standard force. Depending on the width of the sash and the doorway blocked by the sash, the position of the stopper 19 can be adjusted by its displacement in the grooves 12 or 13 of the bearing guide 1 with loose bolts formed by bolts 23 and clamping nuts 24. A limiter 26 is fixed on the bearing guide 1 on similar bolted joints ( Fig. 1, 7, 10) the movement of the sash 4, the position of which on the carrier rail 1 can also be adjusted.

The device 6 for fixing the carriage in the closed position of the sash 4 (Fig. 1, 7) consists of two parts. The first part is made in the form of a flange 27, mounted on top of the housing 14 of the carriage 2 (Fig. 4, 6, 7). The second part is made in the form of a pneumatic cylinder 28 (Fig. 1, 3, 4, 7), for example, the company Camozzi (Camozzi) - http://pnevmo.com.ru/catalog/group_92.htm, containing a piston (not shown), the rod 29 of which is connected to the flange 27 by nuts 30 (Fig. 4, 6, 7), a return spring and a throttle (not shown). The pneumatic cylinder 28 is installed outside, at the top of the carrier rail 1 on the bases 31 (Figs. 1, 4) and in the supports 32, which are fastened with bolts 33 with clamping nuts 34 located in the grooves 12 of the carrier rail 1 (Fig. 2, 3, 5, 7 ) and provide the ability to adjust the position of the pneumatic cylinder 28 on the carrier rail 1.

The locking device 6 of the carriage 2 in the closed position of the sash can be performed similarly to the device 5 described above. It consists of two parts: from the above-described part 18, mounted on the housing 14 of the carriage 2, and the stopper 35 with the pressure element 36 mounted on the carrier rail 1 in a certain place of fixation of the carriage 2 in the closed position of the sash (Fig. 10). A lock groove 37 (Fig. 11) is made on the surface 21 of the part 18, which holds the pressure member 36 of the stop 35 and the carriage 2 from moving in the closed position of the sash. The stopper 36 is located on the same side of the carrier rail 1 on which the stopper 19 is mounted (Fig. 10). In FIG. 10 shows a structure in which the surface 21 of the part 18 with the locking grooves 22 and 37 faces upward, and the stoppers 19 and 35 are mounted on top of the carrier rail 1 in its grooves 12. In another carriage structure similar to that shown in FIG. 4, the part 18 can be installed at the bottom of the housing 14 of the carriage 2, and the stoppers 19 and 35 at the bottom of the carrier rail 1 in the grooves 13 (not shown). For smooth interaction with the part 18, the pressure element 36 is made in the form of a ball. On the part 18, for smooth mechanical interaction with the pressing element 36, a surface 38 is made (Fig. 11), forming an obtuse angle with the surface 21, and the locking groove 37 has a v-shape and depth, which releases the carriage 2 from being fixed by the pressing element 36 when manually moving the sash.

In the initial position, the door is closed, and the locking device 6 keeps the carriage 2 from moving. To open the door and lock the sash 4 in the open position, the sash 4 is manually shifted to the side, and the carriage 2 with part 18 (Fig. 4, 7, 10) moves along the supporting rail 1 until the carriage 2 is locked by the stopper 19. When the carriage 2 is locked in the open the position of the leaf 4, the surfaces 25 and 21 of the part 18 mechanically act on the pressure element (ball) 20, pressing it into the housing of the stopper 19. Then, when the groove 22 is opposite the ball 20, the latter, under the influence of the spring, enters the groove 22, holding the carriage 2 in the open position of the sash 4. Stop 26 prevents further movement of the carriage 2. In a structure equipped with a pneumatic cylinder 28 (Figs. 1, 4, 7), the flange 27 also moves together with the carriage 2, extending the piston rod 29 of the pneumatic cylinder 28 and stretching the return spring installed therein.

To close the door, the carriage 2 is released from fixation by manually sliding the sash 4 in the opposite direction. Moreover, in the design of the mechanism with the pneumatic cylinder 28 (Fig. 1, 4, 7), the return spring of the pneumatic cylinder 28 is compressed, smoothly returning the piston with its rod 29 and the carriage 2 to its original position due to the braking force created by the air resistance, which is etched through the throttle of the pneumatic cylinder 28 with a certain intensity, regulated by the degree of opening of the throttle. In the construction of the mechanism of FIG. 10, the carriage 2 is moved manually until the pressure member 36 of the stopper 35 is locked in the stopper groove 37 of the part 18.

The above examples of designs demonstrate the open arrangement of the locking devices 5, 6, in which the corresponding parts 19, 28, 35, mounted on the carrier rail 1, are displaced vertically in the longitudinal plane of the door relative to the carriage body 14. Such an arrangement of the aforementioned fixing devices and their parts is most convenient, compared with the prototype, for installation, visual inspection and maintenance of the mechanism. The proposed arrangement of parts 18, 19 of the device 5 for fixing the carriage 2 and parts 27, 28 or 18, 35 of the device 6 for fixing the carriage 2 also allows for reliable fixation of the door leaf by using simple known means with spring elements, which ensures high efficiency of the mechanism under vibration in passenger transport.
