Definitions
- the invention relates to a door closer, with an adjustable opening damping as an additional function is provided.
- a third flow channel with a third adjustable Valve activated to enable the so-called end stroke that is, the door with sufficient speed to drop in the lock.
- the main disadvantage of this is that a slowly opening door is braked exactly as a door that opens quickly.
- the throttle valve has however, the task of that when violently belated Doors dampening increased, with one slowly opening door reduces the damping or even is turned off.
- DE-A-2527607 shows a door closer with one valve each for closing damping, opening damping and a closing delay. Doing so Contamination of the closing delay valve avoided, by its valve seat from backflowing oil the opening damping is lifted off. From CH-A-514 062 and DE-C-533 818 door closers are known which only have an adjustable valve for closing damping; opening damping is not provided. A door closer is known from GB-A-2 156 950, at a thermostatic valve in a flow channel the closing damping determines. An opening damping is also not provided here.
- FR-A-2 323 857 shows a door closer with control rod and electrohydraulic blocking of the Open position but without opening damping.
- DE-A-1 806 002 shows a spring arrangement in a door closer without Opening damping.
- the invention is therefore based on the object to create a door closer that mentioned Does not have disadvantages, and which in particular easier to manufacture and easier to Is set, and at what valve contamination does not occur.
- the Valve can also at any point on the flow channel to be ordered. Because when operating the door closer only one valve for the functions mentioned to be set, the setting also becomes essential facilitated. It has been shown that with the same Valve one for both functions Setting value can be achieved, especially with one heavy door. Since the closing force (spring force) is increased, the valve must be closed somewhat to achieve the correct closing speed. This also makes the throttle gap of the opening damping reduced synchronously. That has again with the result that the opening damping is increased and is precisely adapted to the door weight.
- Valve contamination also comes in handy not open, as the valve opens and closes every time fluid flowed through from both sides becomes.
- Figure 1 shows a plan view of a Door closer 1 with a cuboid housing 21.
- the housing 21 is preferably made of a profile piece formed, which each face by means of a Plate 22 is closed.
- a flange 20 is provided, which for attachment of the door closer on the door or on the door frame serves.
- the pressure-tight connection of the profile piece with the plates 22 by means of screws or rivets or by welding, preferably by Electron beam welding.
- the production of the profile piece is carried out by extrusion or continuous casting.
- the Profile piece is e.g. made of aluminium.
- the flow channels are usually from round cross-sectional shape, but can also have other cross-sectional shapes exhibit.
- Figure 2 shows a section along the Line A - A of Figure 1.
- the Piston 32 arranged in the hollow cylindrical, fluid-filled Interior ( Figure 5) of the housing 21 in the hollow cylindrical, fluid-filled Interior ( Figure 5) of the housing 21 in the hollow cylindrical, fluid-filled Interior ( Figure 5) of the housing 21 in the hollow cylindrical, fluid-filled Interior ( Figure 5) of the housing 21 is the Piston 32 arranged.
- This is a hollow piston with the Cavity 8 formed.
- the inside of the piston is the piston formed as a rack, which in a tooth axis 41 (closer axis, Figure 5) engages in Housing 21 is mounted by means of needle bearings 42.
- the Closing axis is on known (not shown) Way coupled with the door or the door frame, so that the door movement in a rotation of the closer axis, or. converted into a linear movement of the piston 32 becomes.
- the piston 32 divides the cylindrical Cavity of the housing in two pressure spaces 10 or 11.
- the piston is in the position shown in its one end position, which in the piston position closed door corresponds. If the door is opened, so the piston 32 over the tooth axis and rack against the force of the springs 5, 6 to the right (in the Drawing) moved.
- the oil in the pressure chamber can first through the bypass opening 17 in Piston flange 36 flow, the piston 32 being practical no resistance due to the oil filling of the housing 21 experiences. From a door opening angle of approx.
- Control rod 82 closes the bypass opening at 70 degrees. In Figure 2, the control rod 82 is not spring-loaded control rod shown, each in the Bypass opening 17 penetrates.
- the control stick can too be designed as a spring-loaded control rod, which the Bypass opening only acted upon and then moved resiliently with the piston.
- valve 30 is a throttle for the Oil flow provided, so that occurs from the valve 30 certain opening damping in function.
- valve 30 blocks the flow channel 45 completely.
- the constricted throttle region arrives in the housing 21 of the valve with a smaller diameter in the flow channel 45 and partially releases it, whereby the oil flow is throttled adjustable.
- the adjusting screw of the valve 30 can be seen from above. Screwing in the screw reduces the Throttling of the oil and thus the damping of the opening Door; the screw movement is accordingly clockwise marked with a minus sign.
- the valve 30 is preferably turned off a plastic material with a high coefficient of thermal expansion manufactured. This allows Changes in viscosity of the fluid with changes in temperature be balanced.
- the pressure-tight closure takes place on the end faces of the flow channel by a ball or plug 35 made of plastic.
- the continuous flow channel 45 shown also allows the valve to be installed on any Point along the flow channel.
- the valve 30 can, as shown in Figure 4, across the flow channel 45 be arranged. However, as in FIG. 6 shown, lie axially in the flow channel.
- a special adjusting screw 4 is provided for Adjustment of the axially lying valve body 40 against the force of a return spring 43.
- Figure 4 shows another flow channel 55, which is also in the housing 2 outside the area the shaft for the tooth axis 41 is arranged.
- a short one Section of this flow channel serves as a fluid line for the end stop function of the door closer, at which at the end of the closing path the closing damping is significantly reduced so that the door is secure falls into the castle.
- the fluid is made the pressure chamber 10 via channel bores 46, 47 via the Flow channel 55 passed into the piston cavity 8 to the damping of the closing process by the fluid in the Reduce pressure chamber 10.
- the flow channel 55 is also a valve 50 arranged to the end stroke to be able to adjust.
- the flow channel 55 is also sealed with plastic balls or plugs 51. Because only a short distance in the end stroke setting this flow channel 55 is used, the rest are used elsewhere.
- the unused part can, for example, with a plug 53 from the end impact part be separated.
- the rest of the flow channel can now be used as an expansion channel.
- the means that the flow channel with the middle unpressurized space is connected by means of a channel bore.
- a pin 57 is also pressed into this channel bore, which, however, does not prevent permeability.
- the pin serves as a stop for the plug 53.
- the So pin is a spring pin or a non-round pin, which ensures the permeability of the hole.
- a ball is now in the flow channel 58 (or more balls) made of plastic or rubber.
- the ball 58 is at room temperature Assembly pushed in up to pin 57 and separates sealing one between the ball 58 and the plug 51 located air-filled flow channel part (compression space) from the oil-filled flow channel part (Expansion space 56) connected to the middle space is.
- An increase in the temperature of the door closer occurs an expansion of the Oil volume.
- the increase in the oil volume in the door closer creates an overpressure in the door closer, which acts on the ball 58. This shifts in the flow channel in the direction of stopper 51 and increases thus the oil intake volume of the door closer.
- the piston 32 is preferably off several parts, a rack as a middle part, one Opening piston flange 36 and a closing piston flange 34 built, these parts together are screwed.
- a piston is particularly simple producible and inexpensive.
- a slide film 33 made of polytetrafluoroethylene (PTFE) provided to the sliding properties of the piston (usually made of steel) in the housing (in the Rule made of aluminum).
- an adhesive disc 92 e.g. made of rubber or PVC, inserted to turn of the clamping plate 91 when adjusting the spring preload to be avoided by means of the clamping screw 71.
- an adhesive disc e.g. made of rubber or PVC, inserted to turn of the clamping plate 91 when adjusting the spring preload to be avoided by means of the clamping screw 71.
- an adhesive disc between the Spring support provided on the piston flange 36 and the spring.
- the door closer Preferably in the door closer two springs 5 and 6 arranged one inside the other.
- the longer spring 5 extends between the piston flange 36 and the clamping plate 91, which means one accessible from the outside of the housing 21
- Tension screw 71 is displaceable in the housing. Means Clamping plate and clamping screw is on the piston acting spring preload set. In the shown middle bias position acts in the shown Piston rest position (door closed) only the long one Spring 5 on the piston.
- the short spring 6 is not effective.
- a spring force is applied to the piston, exercised according to the spring characteristic of the spring 5, corresponding to a door closer size 3.
- the short spring 6 of the piston becomes like this acts that the spring 6 is effective. It results the added spring characteristic.
- both springs 5, 6 are effective (added spring characteristic), from a door opening angle of approx. 60 degrees and smaller, only the spring 5 acts with a correspondingly reduced spring force on the piston 32 a.
- the short spring 6 comes up to one Door opening angle of 90 degrees (or more) not at all used because the piston travel is not sufficient, around the short spring between piston 32 and Clamping plate 91 to be effective.
- the door closer works between opening and closing 0 and 90 degrees only with the spring characteristic of the long one Spring 5, corresponding to a door closer size 2.
- Located at the maximum adjustable spring preload the clamping plate 91 in its right end position. The distance from the rest position of the piston to the clamping plate is now such that the short spring 6 from the beginning always on the piston 32 when opening and closing acts.
- the springs act according to the added Spring characteristic.
- This configuration of the door closer are the DIN values for all preload settings achievable for 2 degrees and 90 degrees door opening.
- FIG. 7 shows a preferred embodiment of the valve 30, which is transverse to the flow channel is arranged.
- the valve has a non-linear Throttle curve on.
