    The invention relates to lifting sliding doors of refrigerated rooms with pressure pressure by means of compression springs with combined one-handed service, which meets all the technological and thermo-energy requirements for reliable operation of a refrigeration device. A door leaf suspended on a rotatable supporting shaft is maintained in an upper position from 3/4 to 2/3 of its weight by means of compression spring springs and from 1/4 to 1/3 of its weight by means of a sliding lever moving on the running rail. In the closed position, the rocker lever is biased downward at the end of the running rail, and the door leaf is lowered to the closed position under pressure from 1/4 to 1/3 of its weight. The holding springs in the upper position are then rotated from the supporting position to the settled position, so that the pressure holding the web in the upper position is released. When the door is opened, the support position set by screwing in automatically lifts the door leaf with its 3/4 weight to 2/3.

    (54) HERMETICALLY CLOSING SLIDING DOOR WITH SPRING CLAMP AND WITH COMBINED SERVICE WITH ONE HAND
    (57) The invention relates to lifting sliding doors of refrigerated premises with pressure pressure by means of compression springs with combined one-handed service, which meets all the technological and thermo-energy requirements for reliable operation of the refrigeration device. A door leaf suspended on a rotatable supporting shaft is maintained in an upper position from 3/4 to 2/3 of its weight by means of compression spring springs and from 1/4 to 1/3 of its weight by means of a sliding lever moving on the running rail. In the closed position
    at the end of the running rail, the rocker lever is biased downwards and the door leaf is lowered to the closed position under pressure from 1/4 to 1/3 of its weight. The holding springs in the upper position are then rotated from the supporting position to the settled position, so that the pressure holding the web in the upper position is released. When the door is opened, the supporting position established by screwing in raises the automatic door leaf with a weight fraction of 3/4 to 2/3. Parallel to the lifting springs for holding in the upper position with an offset of 45 °, hinged compression springs are attached. They alternate with the lifting springs to change their clamping force from zero to the set maximum. The device provides both simple, directionally synchronized, external and internal manual maintenance by means of a lever, as well as simple motorized maintenance with protection against pinching. It allows the use of an automatic locking installation with a slowdown in time from adjustable time relays, short-stroke magnets, a cable pulley with a locking pawl and a multi-link load or with spring tension. 1 hp f-ly, 5 ill.

    The invention relates to a sliding door, which is deposited in the closed position and at the same time hermetically sealing the door lining, as well as a door threshold due to a constant clamping pressure. Hermetic closing (opening) is carried out only with the help of one
    synchronously proceeding technological-hypnotic operation as an additional operation for forwarding (respectively, as a preliminary operation for expanding) both by means of manual maintenance and by means of a motor drive. The automatic entry of the door leaf into the closed position is provided by an additionally installed automatic closing device. Sliding doors of this type are used as doors for refrigerating and freezing rooms, fire resistant doors or as soundproof doors.
    Sliding doors are suspended, suspended on a supporting shaft, pivoted by means of a servicing device, and collapsing radially as a result of a sliding operation. Also known are doors that are movably suspended on roller-suspension hangers tilted out in the spreading zone and which are supported by a stop bar using support rollers. In the closed position, this support is unlocked and the door leaf falls steeply due to its own weight (GDR patent No. 230893, E 05 D 15/16, 1985).
    Another type of sliding doors are such doors, the reinforcement of which is achieved by the inclined plane of the running rail inclined to the floor and to the surface of the wall.
    There are also sliding doors that, in the closed position, have a recess in the running rail, which can be both vertical and diagonal, and which thus lowers the door leaf.
    All doors lack a constant horizontal clamping pressure, which is crucial for hermetic constipation. In all falling door panels, due to its own weight of door leafs, this horizontal pressing force is absent after reaching the floor. The opening and closing are carried out by means of separate longitudinal levers or flywheels, which are held in a high position through the dead center of a circular motion and which require maintenance operations associated with large expenditures.
    Doors that can only be sealed by means of an inclined plane are subject to very high friction with considerable effort.
    On the doors, which are held in a high position on the carrier shaft by means of compression springs, there is a strong and severe stress of the door leaf when closing (as a result of the abrupt transition of the compression springs to pressing pressure).
    The aim of the invention is to improve the performance characteristics by eliminating the drawbacks of the solution with the upper-holding compression springs and supplementing it with some advantages. AT
    In particular, the closing and lowering operations (respectively, lifting and opening) are harmonized so that the doors enter the closed position gently and automatically. This leads to the expansion of the setting for creating an automatic locking installation and simple motorization.
    According to the invention in the open position the door leaf is suspended
    0 on the carrier shaft, which is suspended horizontally from it with a protrusion outwards, and in this position, the cams are supported by one or several compression springs with a compression force from 3/4 to 2/3 of the weight of the door leaf. The rest of the effort to hold in the upper position takes over the moveable lever moving also along the travel rail.
    0 The support of these springs for holding in the upper position is carried out in such a way that they are by means of swinging hinges from a stable bearing shaft.
    5, force closures on the projecting cams of the previously located camshaft, and this proportion of force pushes through the opposing push rods on the cams of the carrier shaft and the weight of the door leaf suspended here.
    In this case, the pushing rod is pivotally attached to the cams of the carrier shaft only at half axial distance 5 compared with the cam shaft. Thus, from a 90 ° rotation of the base shaft, the cam shaft turns only 45 times. .

    The compression springs for holding the doors in the upper position are hinged by means of the spring brackets being pushed into one another in such a way that in the closed position of the door they are on the same straight line with the axles of the carrier and camshaft. The force effect of the lifting spring in this position is removed as a result of the absence of the lever arm to the axis of rotation — the system is lowered. For pressing pressure of the door leaf between the carrier shaft and the camshaft, there are separate compression springs that are installed with an offset of approximately 45. They achieve their maximum forceful effect when the compression springs for holding in the upper position lose their forceful effect. In the upper position, this is carried out in the reverse direction. Through the use of two different types of springs, independently set and set the pressure for holding in the upper position and the pressure of the clamp independently. Attaching the knuckle shaft by means of the servicing device to the position of holding the door in the upper position, the distance of the force action of the compression spring relative to the axis of rotation of the camshaft increases rapidly, and the pre-set spring force causes the door leaf to lift from about 3/4 to 2 / 3
    The residual load held in the upper position is carried by a lever that is also moving on the rail and located in the roller-support suspension on the locking side. The cargo shoulder here relates to a force shoulder of approximately 1: 4 to 1: 8, and to it with the help of hinges, both the door leaf and the lever control mechanism are attached through the sliding bearing. The change in the ratio between the load and power shoulders from 1: 4 to 1: 8 causes, due to the remaining residual load, a very small pressure of the rollers, which is almost imperceptible when pushing the door. Only in the closed position, i.e. at the end of the running rail, this load arm may be deflected downwards, and

    the door leaf is now lowered with a low residual weight.
    Since the force of the spring for holding in the upper position still continues to act and, accordingly, to counteract, a soft hinge of the door leaf is created. It is possible to vary the force separation between the spring to be held in the upper position and the toggle lever by shifting the end of the spring.
    The lowering of the jointly moving power lever is carried out on a stop segment placed on the running rail, which, when lifted by means of a service device, also prevents premature retraction. The effort required to maintain a total of less than for sliding doors of similar design, since the installed spring forces are always preserved. The force-transmitting control levers and the emergency opening lever are located both inside and outside the door leaf in such a way that they are activated respectively in the same direction with respect to expansion, and the ratio of force transfer is chosen so that opening requires only a small additional pressure versus pushing. This results in the desired combined easy maintenance with one hand.
    In addition to the manual maintenance device and in contrast to it, it is possible to arrange a second protruding motor control lever upward, driven by a motor cable or chain. Since the power
    Since the action of the control lever of the motor acts as a mirror with respect to the opposite roller-bearing suspensions, here too the synchronization of the processes of propulsion and
    closing (respectively opening and opening) and thus a very simple motor circuit between two limit switches.

    go composition or people. In the closing process, all control commands are enabled for expansion. The open position of the door can be limited by setting the time relay. After the set time has elapsed, the door closes again automatically.
    In addition to manual maintenance, it is possible, due to the very light force of the slide, which is an extension of the time-delayed automatic closing installation. In this case, on the roller-suspension bracket, from the side of the lock, a discharge cable is attached by means of clamps, which is wound on or removed from a cable drum. The cable drum, in turn, is pulled by a pull rope with a suspended load or by means of a tension spring, always in the direction of rotation of the closing. By spreading, this return force is first overcome and simultaneously fixed by means of a locking pawl on the cable drum against the immediate re-closing of the door leaf. By means of an adjustable electrical time relay from approximately 0 to 300 seconds and a series-connected short-stroke magnet after a set opening time through the coupling rod, the locking pawl is released from the fixation, and the door leaf is again transferred to the closed position, where it is automatically lowered into the constipation due to the system of the invention. At the same time, the load consists of the attached: to each other partial loads, which only in a completely open state all elevated above the floor and provide a reliable operation after loosening the stop doggie. On the other hand, the somewhat greater need for post-retracting the door leaf to push it from a position at rest increases additionally with a full load, but only a small fraction of it. The extra force flow for the automatic closing installation is negligible.

    The vertical position at the bottom is almost horizontal bringing to the stop of the door leaf. Therefore, with the exception of the two lower outer corners, the friction of the sealing rubber associated with wear is eliminated, so that it is possible to use soft shaped rubber, such as a magnetic gasket for refrigerator doors. The lower guiding and pressing of the door leaf is carried out from the outside in a manner known per se by means of a guide bar having an adjustable inclined surface below to slide the door leaf when it is lowered. On the inside, the steel profile is located on the width of the door and elevated above the magnetic strip, which allows the door leaf to be removed from the covering only in the closed position due to the downward sloping surface.
    Figure 1 shows a door leaf with a suspended structure and a maintenance device, a general view; Fig. 2 shows a vertical section of a door leaf with a suspension structure and a lower guide, an open state; fig. 3 - the same, closed state; figure 4 - motor drive; figure 5 - schematic representation of the automatic closing installation.
    On the running rail 2 of the two connected steel corners on the outer side of the door leaf 1, two roller supports 3 are suspended. In order to save the structural height, the roller supports 4 are located within the U-shaped combined rail section 2. The roller supports 3 are stably mounted thanks to the guide rollers 5 The roller supports 3 consist of two lateral vertical roller support plates 6 and one transversely connecting base support roller 7. In the plate walls. 6 are located on the inner side of the bearing shaft 8 for fastening the carrier shaft 9, and the outer side is the bearings 10 of the camshaft 11. The suspension cams 12 having two bearing holes are coaxially welded to the supporting shaft 9.
    Located in the closed lower position, the hole serves as a hinge 13 of an adjustable hanger 14, to which the door leaf 1 is suspended. Offset 45 ° to the door trim 15, the hole provided serves as a hinge for the pushing rod
    16 hinge the push rod 17 to transfer force. Other end of this push rod
    17 is attached to the hinge of the pushing rod 18 of the cam disc 19 on the previously located camshaft 11. The distance between the hinge of the pushing rod 2 (18) and the axis of the camshaft is
    in a ratio of about 1: 2, thus, 90 turns of the cam shaft per 90 rotations of the carrying shaft 9
    11. Next to the supporting shaft 9 and the cam disc 19 of the cam shaft 11, powerful springs are built in to hold the high position 20 and the clamping springs 21 with hinges for connecting the springs 22. Depending on the position of the cam shaft 11, i.e. the distances of the force effect in relation to the axis of rotation of the cam shaft 11, the spring forces vary in a scientific manner between maximum and zero. In the closed position of the door leaf 1, the hinges for connecting the springs 22 for the springs holding in the high position 20 are on the same line as The carrier shaft 9 and the camshaft 11, so that the force action of the springs to hold in the high position 20 in this position is removed. Attached with an offset of 45 ° on the cam disc 19, the clamping springs 21 have reached their maximum and cause the clamping door leafs 1. In the open position of the door leaf 1, the force action of the springs to hold in the high position 20 reaches, conversely, its maximum from approximately 2 / 3 to 3/4 of the weight of the door leaf 1. To hold the residual weight in a high position in 1/4 to 1/3 of the door leaf 1, a swing arm 23 is located on the roller side of the roller 3 located on the closing side, the load arm 24 of which is It takes this weight share through bearing 25

    o on the rolling end and the lifting rod 26 from the cam disc 19 of the cam shaft 11 and transmits through the power lever 27 by means of the roller 28 as a pressing force on the running rail 2. The ratio between the load arm and the force arm of the rocker arm 23 is 1: 4 to 1: 8 defines a very slight pressure of the roller 28 on the running rail 2.
    In the closed position of the door leaf 1, the roller 28 of the power arm 27, which has reached the end of the running rail 2, may deflect with the residual weight through the drain segment 29. The latter warns at the same time the premature pushing of the door leaf 1 while lifting the latter. The door leaf 1 is lifted by means of manual control levers 30 located on the inner and outer sides of the door leaf 1, respectively, of the emergency opening lever 31, the force action of which coincides in direction with the corresponding direction of pushing. Through a lifting hinge 32 lifting rods 26

    The lower guiding and pressing of the door leaf 1 is carried out in a manner known per se, by means of a guide bar 35 having a downwardly adjustable inclined surface for sliding the door leaf 1 when it is lowered. In addition to the control lever 30 or also independently, without the latter, it is possible, according to FIG. 4, to be positioned to control the motor 33 in the opposed roller-support suspension 3, the upward control lever 36 of the motor, driven by the motor cable 37 or chain 37. it can be seen from the description, with the intermediate connection of the lifting hinge 32, lifting rod 26 and cam disc 19 of the cam shaft 11, we have a synchronous flow of the valve
    and closing (respectively opening and radiating) and, thus, a very simple motorized switching installation 34. The gripping of the motor control lever 36 by means of a pull cable 37 or chain 37 is carried out from the point of view of safety through a safety spring 38, which, starting from the adjustable load, in accordance with the compression, mechanically controls the emergency switch 39 located between the connection, so that when people or vehicles are pinched, the door leaf will immediately again azdvigaets.
    The increased pushing force from the rest position bridges in this respect the corresponding circuit between the switch 1 (40) and the switch 2 (41) located at a distance of 20 cm, i.e. emergency shutdown occurs only after a 20 cm run. In addition to manual maintenance, it is possible to attach an automatic closing installation with a time delay according to FIG. five.
    At the height of the running rail 2 on the roller-support suspension 3 on the closing side, a discharge cable 42 is attached with clips, which is wound on the side of the cable drum 43 or wound from the last. The cable drum 43, in turn, always goes in the direction of rotation of the cable-wound cable 44 with an attached load 45 or tension spring 46, if this is not prevented. To achieve a time delay for the door passage, a locking pawl 47 is located on the side of the cable drum 43, which is released from the fixings by means of a connecting rod 49 and a short-stroke magnet 50 after a period of time set on the electronic time relay 48. The door leaf is then loaded with a weight 45 or spring 46 into the closed position, where it is automatically lowered into the lock by means of the system described above. The tensile force is created by the partial loads 51 attached to each other, which are only in a completely open state all

    high above the floor and provide a reliable run-up after loosening the locking pawl.
    On the other hand, the increased pushing force from the quiescent position does not increase immediately with full, but only with partial load 5. The same is true for installing one or several tension springs 46.
