Definitions

  • the invention relates to a door closer with the features of the preamble of patent claim 1.
  • a door closer of the type mentioned at the outset which has an energy store composed of two closer springs, of which the first partial energy store is used for closing during normal operation and the second energy store is only switched on when required, is known from DE-OS 42 37 179. It is a hydraulic door closer with two closer springs, whereby only the weaker closer spring is effective in normal operation and the stronger closer spring is detected by an electrical locking device and is only activated in an emergency via a fire alarm, fire alarm or the like. However, this means that if wind pressure or another obstacle occurs in the door's closing path, complete closing cannot be guaranteed as long as the electrical locking device is switched on.
  • So-called servo door closers are known from DE-OS 32 34 319 and DE-OS 34 23 242. They are hydraulic door closers with a closer spring and an electric motor to pretension the closer spring when it is opened.
  • the electromotive pretensioning of the closer spring eliminates or at least reduces the opening resistance of the door during manual access.
  • the closing process then takes place automatically as in a conventional hydraulic door closer under the action of the closer spring. With each opening process, the closer spring must be preloaded again by an electric motor to maintain the servo effect.
  • the invention has for its object to develop a door closer of the type mentioned, which has low opening resistance in normal operation and ensures a complete closing of the door.
  • the discharge of the second partial energy store can also be controlled via a sensor device which monitors the closing process, for. B. via a device that determines whether the closing movement is interrupted before reaching the closed position.
  • the sensor device detects z. B. current operating data of the door closer or the door, z. B. the operating pressure in a piston-cylinder system in the door closer or the movement speed or the direction of movement of the door or door positions or changes to this data.
  • the second partial energy store represents a reserve energy store.
  • the timing element or the sensor device ensures that the second partial energy store is automatically effective for securely closing the door when the door does not reach the closed position under the action of the first partial energy store.
  • the second partial energy store can interact with a controllable blocking device.
  • the blocking device or an actuator of the blocking direction is controlled via the timer or the sensor device.
  • the blocking device can block the second partial energy store hydraulically, pneumatically, mechanically or electrically.
  • the timer is preferably adjustable or programmable.
  • the timing element can be arranged in an overflow device in a piston-cylinder device and can be determined by the flow resistance of the overflow device.
  • the overflow device can control the discharge of the second partial energy store.
  • the partial energy stores can be formed by pistons connected in series in a cylinder.
  • a flow valve preferably an adjustable flow valve, can serve as the timing element of the overflow device.
  • an overflow channel or an overflow groove can also be arranged in the cylinder or in the piston.
  • different resistance can be switched in the overflow device or different overflow devices with different resistance can be activated one after the other, e.g. B. by successively an overflow groove as short-circuit groove, then an overflow channel with adjustable flow valve and finally an overflow groove as short-circuit groove again; instead of the short-circuit grooves, short-circuit channels can also be provided.
  • the discharge of the second partial energy store it is thus possible for the discharge of the second partial energy store to have successive discharge phases of different discharge speeds. It can be realized that the time-delayed discharge of the second partial energy storage z. B. is initially very slow and if after a certain time the door has not yet reached its end position, then the discharge speed is increased and thus the second partial energy store contributes more to the closing in this phase.
  • phase in which the second partial energy store serves to provide a strong force for the initial rapid acceleration of the door when closing, a second phase in which it is only discharged relatively slowly and contributes little to the closing and in the event that the door has not yet reached the closed position after a certain time, a third phase takes place, in which the second partial energy store is quickly discharged and the door closes.
  • the first partial energy store expediently stores less energy than the second energy store, which is delayed by the time-dependent control, as required, for closing.
  • Structurally particularly simple solutions are obtained if closer springs, preferably helical compression springs, are provided as the partial energy store.
  • the springs can be arranged in the cylinder of a pneumatic or hydraulic piston-cylinder device and cooperate with the pistons tightly guided in the cylinder.
  • the door closing mechanism shown in FIGS. 1 to 3 has a housing 1 in which a hydraulically damped piston 2, an auxiliary piston 22 and a spring arrangement 3 are located in a cylindrical bore.
  • the piston 2 is connected to a closer shaft 4 which is rotatably mounted in the housing 1, in the illustrated case via a pinion.
  • the pinion consists of a pinion 4a which is connected in a rotationally fixed manner to the closer shaft 4 and a rack 2a fixed to the piston.
  • the pinion 4a or the closer shaft 4 rotates counterclockwise in the illustration in the figures.
  • the piston 2 is moved to the right.
  • the movement takes place in the opposite direction, i.e. the pinion 4a or the closer shaft 4 rotates clockwise and the piston 2 is moved to the left.
  • the closing spring device 3 consists of a closing spring 3c and two reserve closing springs 3a, 3b.
  • the springs 3a, 3b, 3c are compression springs. These are concentrically arranged helical compression springs.
  • the closing spring 3c is supported with its left end directly on the right end face of the piston 2 and with its right end on an auxiliary piston 22.
  • the auxiliary piston 22 is received in the cylinder space to the right of the piston 1 and is also guided as a hydraulic piston in the cylinder space.
  • the reserve closing springs 3a, 3b are each supported with their left end on the auxiliary piston 22 and with their right end on the right front end of the housing 1 on a housing cover 1r screwed in there.
  • the auxiliary piston 22 is cup-shaped and consists of a tubular piston skirt 22a and a piston crown 22b.
  • the piston skirt and piston crown can consist of one part (FIGS. 1 to 4) or, e.g. shown in Figures 5 and 6, of 2 parts, the pressure-tight, for. B. are connected by an adhesive or welded connection.
  • the diameter of the piston skirt 22a at the piston bottom end of the piston 22 can be made smaller than in the area in which the piston skirt takes over the axial guidance in the piston.
  • the inner reserve closing spring 3a is received concentrically in the interior of the piston.
  • the left end of the spring 3a is supported against the piston crown 22b. It protrudes from the piston to the right and is supported with its right end on the housing cover 1r.
  • the second reserve closing spring 3b is arranged concentrically with the spring 3a. It is supported with its left end against the end face of the piston skirt 22a, with its right end it is supported against the housing cover 1r.
  • the auxiliary piston 22 is guided in the cylinder via the piston skirt 22a, the left end of which forms the collar 22c.
  • the closing spring 3c is arranged concentrically with the piston outer jacket 22d.
  • the spring 3c is supported with its right end against the collar 22c, with its left end against the right end face of the piston 2.
  • the sealing element 23 which seals the hydraulic chamber 32a from the hydraulic chamber 32b.
  • FIGS. 4 to 6 A further variant for the arrangement of the spring elements 3 and the auxiliary piston 22 is shown in FIGS. 4 to 6:
  • the auxiliary piston 22 is rotated by 180 ° with respect to FIGS. 1 to 3, so that the piston head 22b points to the right.
  • the concentric reserve springs 3a and 3b are supported with their left ends against the piston crown, with their right ends against the housing cover 1r.
  • the closing spring 3c is mounted concentrically to the inside of the auxiliary piston 22. Its right end is supported from the inside against the piston crown 22b, its left end against the right end face of the piston 2.
  • This arrangement offers the advantage over the arrangement in FIGS. 1 to 3 that the sealing element 23 arranged in the piston skirt 22a only moves over a cylinder surface is that can not come into contact with the closing spring 3c.
  • the closing spring 3c could damage the cylinder wall surface in FIGS. 1 to 3 and thus impair the functionality of the sealing element 23.
  • the cylinder interior and the interior of the pistons 2 and 22 are filled with hydraulic oil ( Figures 1 to 6).
  • the piston 2 has a sealing element 2d (preferably made of elastomer material) and divides the cylinder space into a hydraulic space 31 on the left of the sealing element 2d and a hydraulic space 32 on the right of the sealing element.
  • the hydraulic space 32 is in turn divided by the sealing element 23 (preferably made of elastomer material) into a space 32a, which receives the closing spring 3c, and a space 32b, which accommodates the reserve springs 3a and 3b.
  • the hydraulic chamber 31 is connected to the hydraulic chamber 32 via hydraulic channels 36 (FIG. 8) which contain flow valves for regulating the closing and opening speed, as is known in conventional door closers.
  • a spring-loaded check valve 2b is arranged in the left end face of the piston 2, which opens during the opening movement when the piston 2 is moved to the right in the figures.
  • a pressure relief valve 2c is arranged in the piston 2.
  • the sealing element 23 can either be mounted in the piston skirt 22a, as shown in FIGS. 1 to 4, or, as shown in FIG. 5, at a suitable location in the cylinder bore.
  • an overflow channel 33 is formed which connects the hydraulic spaces 32a and 32b.
  • the overflow channel contains a throttle, preferably an adjustable regulating valve 33a, with which the flow rate of the hydraulic fluid through the channel and thus the speed of movement of the auxiliary piston can be adjusted.
  • a shut-off valve 33b in the overflow channel is closed when the door has reached its end position during the closing process.
  • a spring-loaded check valve 24 is provided in the piston crown 22b of the auxiliary piston, which opens to overflow the hydraulic fluid from space 32b into space 32a when the auxiliary piston 22 is moved to the right.
  • the door closer shown works as follows. The door is opened by hand. The closer shaft rotates with the pinion 4a counterclockwise and the piston 2 is forcibly moved to the right against the action of the closing spring device 3. From the initial position in FIG. 1, the auxiliary piston 22 resting on the piston 1 is taken to the right and the reserve closing springs 3a, 3b are compressed. The closing spring 3c installed in the pretensioned position remains in its pretensioned position.
  • the check valve 24 opens, so that the hydraulic oil displaced by the piston movement can flow from the space 32b into the space 32a.
  • the piston 2 and the auxiliary piston 22 each reach the right end position in which the reserve closing springs 3a, 3b are maximally compressed.
  • the closing process then takes place automatically under the action of the closing spring device 3.
  • the door should be accelerated quickly and with greater force.
  • This high-speed phase I lasts e.g. 2 seconds.
  • the hydraulic space 32b is connected to the hydraulic space 32a through the groove 37a (FIG. 7), which causes a hydraulic short circuit.
  • This allows the hydraulic fluid to flow from the space 32b into the space 32a and the reserve closing springs 3a, 3b move the auxiliary piston to the left with great force.
  • the movement of the auxiliary piston is transmitted to the main piston via the closing spring 3c; at the same time, the closing spring also pushes the main piston to the left.
  • the closer shaft 4 is rotated by the movement of the piston 2.
  • the auxiliary piston 22 moves very slowly in a slow speed phase II in accordance with the setting of the throttle valve 33 by the force of the reserve closing springs 3a, 3b Left.
  • the sealing element 23 in the auxiliary piston 22 is located on the web between the groove 37a and the groove 37b. The hydraulic fluid displaced by the movement of the auxiliary piston 22 can now only pass through the overflow channel 33 from the hydraulic space 32b into the hydraulic space 32a.
  • the piston 2 moves during the slow-running phase of the auxiliary piston 22 essentially under the action of the relatively weak closing spring 3c. This means that the piston 2 runs ahead of the auxiliary piston accelerated or faster.
  • the speed of movement of the auxiliary piston is damped in slow speed phase II by the regulating valve 33a located in the overflow channel 33; this speed can be adjusted with the regulating valve.
  • This is e.g. B. set so that the entire slow speed phase II of the auxiliary piston 22 is about 25 sec.
  • the shut-off valve 33b is open when the door is open. As soon as the piston 2 reaches its left end position when the door is closed, the shut-off valve 33b in the overflow channel 33 is closed by a corresponding mechanism. The auxiliary piston 22 is thereby held in its current position, and the residual energy stored in the reserve springs 3a, 3b is retained. This means that the slow speed phase is usually stopped prematurely.
  • the overflow channel 33 remains open.
  • the auxiliary piston 22 moves slowly, for example up to a door angle position of, for example, 45 °, from which the sealing element 23 is located above the groove 37b.
  • a hydraulic short circuit now occurs again between the hydraulic spaces 32b and 32a, and the residual energy stored in the reserve springs 3a and 3b is used in addition to the energy of the spring 3c to close the door.
  • the weaker closing spring 3c is simultaneously compressed and the starting position of the door closer shown in FIG. 1 is again obtained.
  • FIG. 5 Another possibility for controlling the movement of the auxiliary piston 22 is shown in FIG. 5.
  • the sealing element 23 is located at a corresponding point in the cylinder bore and the grooves 37a, 37b are made in the piston skirt 22a of the auxiliary piston 22.
  • FIGS. 8 to 10 Another possibility for opening and closing the flow opening of the channel 33 is shown in FIGS. 8 to 10.
  • a seal 35 (preferably made of elastomer material) is inserted into the piston 2.
  • the piston 2 is guided so that it cannot rotate about its longitudinal axis.
  • the seal 35 is attached so that it closes the mouth 33c of the overflow channel 33 in the hydraulic space 32a in the left end position of the piston 2 when the door is closed.
  • the seal 35 can also be supported in its effect by a stored spring element.
  • the overflow channel 33 can be designed such that the deep hole 36 is closed at a suitable point by a plug 34. 8 shows the overflow channel 33 (as part of the deep hole), the mouth 33c and the adjustable regulating valve 33a to the right of the sealing plug. To the left of the sealing plug 34 is the known hydraulic circuit for the piston 2 for controlling the end stroke and the closing time.
  • the overflow channel mouth 33c is closed by the sealing element 2d embedded in the piston 2. The overflow channel opening 33c is then in the closed position of the piston 2 on the sealing element 2d.
  • the swing energy of the door can then recharge the already preloaded reserve energy store, which at the same time dampens the opening movement of the door and signals the end of the door opening angle to the user through increased opening resistance.
  • the closing spring 3c is weaker than the sum of the reserve closing springs 3a, 3b connected in parallel.
  • the closing spring 3c is designed so that during normal operation, if there is no special closing resistor, e.g. in the form of wind pressure or obstacles in the closing path, is able to close the door completely, i.e. to move the piston 2 to its left end position before the auxiliary piston 22 has completely run through its slow-running phase II and thus before the reserve energy store with the reserve spring 3a, 3b is substantially discharged.
  • control can be provided via a sensor device which cancels the hydraulic determination or deceleration of the auxiliary piston 22 by actuating the valve 33a or 33b if the door does not close properly.
  • a sensor device can, for. B. be designed such that it monitors the pressure in the hydraulic chamber 31 by detecting the pressure drop that occurs when the closing process is interrupted before the door comes into the fully closed position. This drop in pressure always occurs when the door is stopped during the closing process.
  • a hydraulic control piston can be operated, which can be arranged in a hydraulic connection system that connects the hydraulic chambers 31, 32a or 32b formed in front of and behind the piston 2. The hydraulic control piston can then switch the valve 33a or 33b under the effect of the pressure drop.
  • Sensor devices can also be used which detect the door movement or correspondingly moving components of the door closer during the closing process or a delay or the stopping of the closing movement before the end position is reached.
  • a mechanical blocking device can also be provided in other exemplary embodiments which mechanically blocks the auxiliary piston 22, preferably in a fixed blocking position in which the reserve closer springs 3a, 3b be kept on standby in the maximum tensioned position.
  • This blocking device can be controlled in a time-dependent manner or by means of a sensor device in a manner corresponding to the previous exemplary embodiments, so that the reserve closer springs 3a, 3b come into effect when necessary and completely close the door.
  • a spring plate-like support member that is linearly guided in the spring receiving space can be provided, in particular, if the blocking takes place via a mechanical blocking device.
  • This spring plate-like support member does not have to be hydraulically tight in the cylinder. This means that the same pressure is formed in the cylinder spaces 32a and 32b, namely without pressure when closing, as in the spring receiving space of a conventional hydraulic door closer.
  • the mechanical blocking device can be designed as a detent ball device which interacts with the spring support member.
  • the locking balls can preferably be controlled via a hydraulic control piston between a blocking and a release position, wherein the hydraulic control piston can be controlled in the manner described above depending on a sensor device.
  • the closing spring device and the reserve spring device can each be composed of a different number of springs.
  • the closing spring 3c can be supported on the piston 2 on the one hand and on the support member on the other hand, or alternatively on the end of the cylinder space 32b, in particular in the case of designs with a spring plate-shaped support member which also supports the reserve springs 3a, 3b supported on the spring plate-like support member.
