Definitions
- the invention relates to a door closer with the features of the preamble of Claim 1.
- the door closer consists of a housing in which a Lift mechanism in the form of a spring and a damping piston are available.
- a damping fluid in the hermetically sealed housing, to influence the operating sequence of the door closer. From the case protrudes a drive axle on which a linkage on the one hand and on the other hand is attached to the door leaf or door frame to be moved.
- the energy storage in the form of the spring is the necessary Energy supplied for the subsequent closing process.
- Such a door closer is known from EP-A 0 207 251.
- Door closer is a door closer with two closer springs, wherein each closer spring is assigned a piston, d. H. the The closer spring works with the inner piston and the closer spring with the outer one Pistons together.
- These pistons act on a mechanical Gear the closer shaft.
- the mechanical transmission is in the case of the inner one Pistons a cam gear with cam roller, which with a closer shaft fixed Cam interacts.
- the mechanical transmission in the case of the outside Piston is designed as a pinion, the piston with a rack is connected, which meshes with a fixed gear on the closer shaft.
- the different mechanical gears work in different angular ranges the closer shaft with different gear ratios.
- the two mechanical gears form a composite gear, by which realizes a path-dependent variation of the gear ratio becomes.
- a door closer which also has a through a spring arrangement loaded in the closing direction, mounted in the closer housing Has closer shaft, with a displaceable piston of a damping purpose serving hydraulic piston-cylinder unit in torque transmitting Intervention is.
- a check valve acted upon by the spring assembly Piston head has a backflow channel on the housing side bypassed from a certain door opening angle. In the return flow channel a throttle valve damping the opening movement of the door leaf is integrated.
- the piston head, which is loaded by the spring arrangement is provided with a bypass channel small channel cross-section, starting from the spring arrangement Reversed piston side is extended towards the closer shaft. By this bypass channel also dampens the door opening movement.
- a method and arrangement for controlling the force of a locking device can be found in DE 35 35 506 A1.
- the door will be there by means of a locking device in the form of a door closer and on it linkage arms articulated to the door frame connected.
- the control of the different force to open and Subsequent automatic closing of the door is carried out by relocation the end of the in comparison to the door locking device Linkage to the moment exerted by the locking device on the door in separate phases of opening and closing the door, in corresponding Way changed.
- This arrangement is concerned is a device that works with external energy, i.e. it is an electric motor is provided which shifts a slide and at the same time determines its location in a management link.
- the engine control made according to the desired opening angle.
- US 4,979,261 discloses a door closer with a variable articulation position. Due to a gear wheel attached to the closer shaft which rolls on the door automatically becomes the point of attack of the Linkage and thus the entire moment consideration changed. By this mechanical type achieves a reduction in the opening force. while increasing the closing force.
- a further US patent 3,818,637 describes a device which allows a door to be opened quickly.
- the US shows a device that opens a door with a linear force 4,231,192.
- a linear force 4,231,192 is connected via a corresponding lever system with an external energy in the form of a power supply linear course of the force at the door depending on the opening angle been achieved.
- a door closer that works with two pistons is the US 4,040,144 remove. This system also works with an external energy Form of air.
- a device in the form of a door closer that is used in the Swedish Design 469 342 is shown. consists of a housing in which two pistons are movably arranged. There are also two springs which are each directly assigned to a piston and to this in the same Act in the direction. The other piston is with a piston rod connected, the rear end in a central bore of the second Piston is sealed. The diameter of the two pistons are different.
- the liquid flow of the Damping medium via various channels in connection with valves controlled. This measure ensures that the force to open the door is small and still a great force for the final phase of the Closing process is present.
- the object of the invention is achieved with the subject matter of patent claim 1.
- the closing torque can be lower be what a force transmission Ü ⁇ 1 means. Only in a third part of the Closing process, namely in the area where the door is in the proper If the closed position is to be transferred, the force ratio Ü> 1, d. H. the Closing moment is significantly larger than the opening moment.
- the idea according to the invention thus includes programmability in several areas.
- the door piston chamber 24 is preferably in the Side wall located channel 53 with the spring chamber 21 operatively connected. Now the spring piston 2 moves towards the door piston 3, i.e. the feather 1 relaxes, so must next to the volume displaced by the spring piston 2 the space 25 also that of the pinion cage 9 in the inner piston space Record 26 displaced volumes. The way of the door piston 3 is therefore larger than that of the spring piston 2. which means that it removed from this. Seen from the point of view of force is its strength smaller than that of the spring piston 2, which means a translation ⁇ 1.
- a mathematical analysis reveals the force transmission Translation factor. The effects are shown in FIG. 2. At only the channels are shown in the schematic considerations which are also significant for this application.
- FIG. 7 shows the door closer in area c of the closing process.
- the sections are below the spring piston 2 and the door piston 3 (small letters) and the states (large letters) of the two pistons shown.
- the channel 51 inside the door piston 3 is over the pocket 71, which is located in the side wall, opened. All belonging together Channels, except for channel 53, which is always open, are in this Angular range ineffective, the channel 50 can e.g. only through that Pocket 70 can be opened because pocket 68 is on a different level lies and can not cause an opening. channel 50 remains therefore closed.
- the pockets and channels are on the side on the piston rim in several levels, each at the same height with the outlet openings of the channels.
- the closing process of area a is shown by the schematic representation shown in Figure 8. This area is actually a comparison to the previously described areas very small and therefore to better understanding has been reproduced significantly enlarged.
- the Area a is the area where the door actually closes, which means that a much higher force than for the normal Closing process is required because of the existing on a door Lock, the latch of the lock also securely in the striking plate must snap into place.
- the channel 49 connects the door piston chamber via the pocket 69 24 with the inner piston chamber 26. At the same time, the channel 48 Via the pocket 68, the inner piston chamber 27 with the chamber 25.
- the channel 50 is also opened via the pocket 70, but this opening is ineffective, because a flow of the damping medium through the check valve 81 prevented due to the excess pressure in the inner piston chamber 26 becomes.
- Ü> 1 means that the door piston 3 at a lower speed, but with a higher force than the spring piston 2.
- the movement of the door piston 3 is damped via a throttle 83.
- FIG. 10 In a further embodiment of the inventive idea is a hydraulic solution with external throttles and translation transitions in Figure 10 and others explained in more detail.
- This embodiment shows with external chokes and smooth transitions for the most varied Translations to that programming is also possible here.
- the Door closer is here in a schematic sectional view in the Top view has been rendered.
- the Housing 5 In the housing 5 is the Spring piston 2 with the spring 1.
- a door piston 3 with teeth 4 a pinion 8 and a pinion cage 9 are shown.
- the inner bulb space 26 is with a side plate 15 through a bore 90 and with another side plate 16 connected by a bore 91.
- Corresponding is also the inner piston space 27 through bores 92, 93 with the Side plates 15, 16 are able to match the damping medium regulate the desired processes or prevent the outflow.
- Sectional representations are shown in FIG. 11 and also in FIG been in which the side panels, which are interchangeable are better represented in detail. Through this representation clarifies that the existing channels, holes, pockets, etc. with the grooves, pockets or channels also present in the pistons controlled in a controlled manner when the side plates meet become.
- the area b for the closing process is first explained in more detail. In this area has a small force on the door piston 3.
- the bags 112, 113 of the side wall 15 of the housing 5 are above the grooves 100, 106. This is the connection from the inner piston space 26 to the space 25 produced, namely via the bore 90. the groove 100 and the pocket 113, a channel 99 with throttle 88 therein, the pocket 112 and the Groove 106.
- the connection between the inner piston chamber is also analogous 27 connected to the door piston chamber 24, namely via the Bore 93, a groove 105, the pocket 116, a channel 104, a pocket 115 and a groove 103. The state as shown in FIGS.
- section a which means that the piston 3 moves to the left: accordingly, the pockets and channels are dashed on the shown on the right.
- the groove 106 Groove 102 and groove 103 over the corresponding associated pockets 110, 112, 114, 115, so that the connections to the inner piston chamber 27 with the space 25 and the inner bulb space 26 with the door bulb space 24 are made.
- the pressure compensation for the spring piston 2 in last part of area a is achieved in that a pocket 111 in the side plate 15 lies above a groove 107 in the spring piston 2, and thus via a bore 94 in the spring piston 2, the groove 107, the pocket 111, a channel 96 with throttle 89 therein, the pocket 112 and the Groove 106 connects the spring chamber 21 to the chamber 25.
- the transition points In FIG. 10 this is for the transition point U1 between the areas b and c shown. This measure switches between the different translations not abruptly, but is almost smoothed out.
