Definitions

  • the invention relates to a door opener with a housing, with a pivotally mounted in the housing Fallengroundianu, with a pivoting limit and with a stop, wherein the stop and the pivot boundary are arranged in the manner to each other, that the pivotal movement of the Fallengrund stressess in the closing direction by the Swivel limitation and the stop is limited.
  • electrically operated door openers in particular electromagnetically actuated door openers
  • These usually have a pivotable door latch into which a lock latch engages in the locked state of a door equipped with a corresponding door opener and is held there by a latch base body with a hook-type or anchor-type stop as a rule.
  • a pivotable door latch into which a lock latch engages in the locked state of a door equipped with a corresponding door opener and is held there by a latch base body with a hook-type or anchor-type stop as a rule.
  • To release the door pivots the Fallengrund emotions against a spring force generated by a closing spring in an open position, so that the latch is released and the door can be opened.
  • To initiate the pivoting process of the Fallengrundgropers have generic door openers usually electrically actuated release means, which are triggered for example via push-buttons of persons or automatically by access control units.
  • Such a door opener is for example from the DE 10 2004 037 827 A1 known and has already proven itself.
  • the latch base body is pivoted by the spring action of the latch base body with the closing spring from its open position to the closed position.
  • the pivoting movement of the latch base body in the closed position or in the locking position of the door opener is limited by a stop region on the trap base body.
  • This stop area strikes abruptly and acoustically perceptibly against a region projecting from the housing body to complete the closing movement of the falling body body. which limits the extent of the pivoting movement in the closing direction of the case main body. This area is referred to below as the slewing limitation.
  • the invention is therefore an object of the invention to provide a door opener, on the one hand allows a rapid opening movement of the door latch for prompt release of the door and on the other hand is considerably reduced or silent in its noise during the backward fall of the Fallengrund stresses in the closed position.
  • the solution of the problem with a door opener with a housing, with a pivotally mounted in the housing case base body, with a pivot boundary and with a stop, the stop and the pivot boundary are arranged in such a way to each other, that the Pivoting movement of the Fallenground stressess is limited in the closing direction by the pivot boundary and the stop, and the pivot limiting the door opener has at least one stop damping, and that the pivoting movement of the Fallen ground stresses in the closing direction is limited by the fact that the stop abuts at least partially against the stop damping of the pivot boundary.
  • a stop damping is thus arranged in the door opener, which is arranged between the Fallengrundköper in the closed position of the door opener and the pivoting limit of the door opener.
  • Pivot limits in the context of this invention are areas or means in the door opener, which limit the extent of pivotal movement. This may be, for example, special projections, etc., but in particular also planar areas that prevent their positioning by a continuation of the pivotal movement of the Fallengrund stresses in the closed position.
  • the pivot boundary cooperates with a stop which abuts the end of the closing movement against the pivot boundary.
  • the pivot limitation in the contact region between the stop and the swivel limiter at least partially a stop damping which prevents a direct collision of the swivel limiter and stop or is at least partially arranged between the stop and the swivel limiter.
  • the stop damping to a non-metallic material, which effectively reduces the disturbing noise that is caused by a collision of the stop on the pivot boundary.
  • the swivel limitation is arranged with stop damping on the housing. This embodiment is preferred because in this case no modifications of the trap body with respect to conventional door openers are required. Rather, the necessary constructive measures can be limited to changes in partial areas of the housing, so that the sensitive control of the trap base body does not have to be adapted.
  • a multi-part stop damping dampens particularly well the noise of a door opener according to the invention.
  • a multi-part stop damping against a one-piece stop damping damping effect can be distributed selectively and simultaneously homogeneously in the attack area between trap body and swivel limitation. In this way, on the one hand one-sided signs of wear can be prevented.
  • the uniform distribution of the damping effect over the entire stop area is thus possible in a surprisingly simple manner, without requiring a full-surface equipment of the swing limit with a stop damping in the contact area with the stop.
  • the damping element has at least two similar subunits, wherein the at least two subunits are preferably arranged parallel to one another.
  • the arrangement of similar subunits allows a homogeneous damping effect of the entire damping element without consuming adjustments.
  • the parallel arrangement of two subunits of the damping element at the pivot boundary ensures that the abutment effect of the stop on the damping element is evenly distributed to all subunits of the damping element during a closing operation of the door opener.
  • the stop damping has a material suitable for noise reduction. This is preferably a material with elastic properties, preferably materials such as plastics or rubbery compounds are used here.
  • the attachment of the elastic Material of the stop damping is advantageously positive fit in the door opener, as can be dispensed with additional fastening aid in this way.
  • a quick and cost-effective replacement of the stop damping which may be necessary, for example, by wear and tear, make.
  • the elastic material of the stop damping is secured via a tongue and groove connection in the door opener.
  • This connection combines the connecting means for fixing the elastic material in the door opener with the resilient damping component of the stop damping. In this way, no additional materials are needed to reliably bond the elastic material to the sleeper, such as typically adhesives, screws, etc.
  • Another preferred damping element has at least one spring element.
  • the spring elements used here are preferably metallic spring elements such as compression springs in the form of coil springs etc. Alternatively, however, spring elements may be used, for example, suitable plastic materials.
  • the door opener has at least one spring element in the form of a shaped spring, which is clamped between the pivot-axial side region of the trap base body and a counter element fixed in the door opener housing. Due to the lateral arrangement of the shaped spring in relation to the pivoting plane of the latch base body, a particularly space-saving arrangement of the damping element is possible. In this way, the housing proportions of a door opener invention are insignificant or not changed compared to conventional door openers. This allows the particularly unproblematic retrofitting of a conventional "loud" door opener by a low-noise door opener according to the invention, without requiring expensive installation work is necessary.
  • the stop is in several parts and the subregions of the stop are arranged at a distance from one another.
  • the use of a multi-part stop, the portions of which are spaced from each other, allows a homogeneous distribution of the impact force or the splitting of the total stop force on several portions of the stop, so that the stop force is not fixed to a single point.
  • a multi-part stop has less wear compared to a one-piece stop.
  • the stop on the trap body and the swing limit with stop damping fixedly arranged in the door opener housing. In this way, it is possible to resort to already proven case base bodies, so that no adjustments need to be made with regard to the pivoting mechanism of the trap base body.
  • the arrangement of a two-part stop in the door opener is particularly advantageous, with the two stop parts being particularly favorably arranged in the two lateral axial end regions of the trap base body.
  • This particular arrangement of the stop members seen in the axial direction of the beginning and end of the trap body has been found to be particularly stable and reliable.
  • this special arrangement requires little space and is characterized by the reliable noise reduction.
  • a multi-part stop attenuation is preferably also attached to the pivot boundary, wherein at the end of the closing movement of the case base body ever a portion of the damping element interacts with one of the two stop parts and thus effectively reduces the stop sound.
  • the at least one stop, which abuts against the impact damping of the pivot boundary, and the latch stop, against which a door latch can strike in a preferred embodiment on a common leg of the Fallengrund stresses.
  • This embodiment is preferred because the trap base body here has a relatively simple geometry and thus is inexpensive to manufacture.
  • the arrangement of the latch stop on a first leg and the stop, which abuts against the stop damping, on a second leg of the case base body is possible.
  • the trap body is at least slaughterschklig created.
  • This particular embodiment is advantageous because the spatial separation of the damping stop of the functionally fixed arrangement of the case stop the positioning of the stop damping in the door opener is variable and z. B. can be tailored to limited space availability in the door opener housing.
  • the door opener on a friction brake with at least two friction surfaces.
  • a friction brake is any type of brake, the braking effect of which is generated by rubbing together and in particular by the juxtaposition of two friction surfaces. Friction brakes have the advantage that in addition to the high reliability they have a small footprint and also by, for example, the variation of the friction surfaces forming Material or the size of the contacting friction surfaces, etc. can be adapted particularly well to individual operating conditions of the door opener.
  • the friction brake is arranged in the door opener such that it acts between the case base body and the door opener housing.
  • This particular arrangement makes particular to the storage of the Fallengrund stresses in the door opener no special requirements.
  • a change of a trap body with integrated bearings to a trap body with separate bearing axis without additional adjustments of the friction brake is possible.
  • a first friction surface is formed by a brake element, which is preferably attached to the bearing axis of the case main body or the door opener housing.
  • the second friction surface is correspondingly formed by the part of the door opener which is moved along the first friction surface of the brake element. If the brake element is fastened, for example, to the door opener housing, the second friction surface is expediently formed by the at least one partial region of the fall base body which is guided along the brake element or runs along the first friction surface. The resulting friction between the first friction surface of the brake element and the second friction surface ultimately leads to a reduction of the stop sound.
  • the friction brake has at least one brake element with an elastic material, wherein the at least one brake element acts in the axial direction on the end face of the latch base body.
  • the use of elastic materials in the brake element is advantageous, since the braking effect of the brake element can be adjusted or varied particularly well, for example by adjusting the elasticity of the elastic material.
  • By an end face in the axial direction of the braking element on the case main body a particularly uniform braking force is effected on the case main body. Further, a readjustment of the friction brake by a simple axial displacement of the case base body via suitable actuating means is possible.
  • the braking element in this embodiment of the door opener is, for example, flat-cylindrical or else brake block-like brake elements, which are preferably traversed in the axial direction of the pivot axis by the bearing axis of the latch base body. In this way, at the same time the positioning of the brake element is secured.
  • the friction brake acts between the trap base body and a rotationally fixed bearing axis of the trap base body.
  • a pivoting movement of the case base body pivots about the bearing axis, which is preferably mounted rotatably in the pivoting direction.
  • An advantage of this embodiment is in addition to the particularly space-saving Embodiment of this embodiment, the possibility of the braking effect of the friction brake on, for example, the axial length of the braking region, which is formed by the contact surface between at least one brake element of the friction brake with the second friction surface set. Individual customer requests with regard to the noise damping of the door opener can thus be taken into account particularly well.
  • Possible brake elements of the friction brake which act between the case base body and the rotationally fixed bearing axis of the case base body, are, for example, axially extending brake strips, half cylinders, etc.
  • the friction brake has at least one hollow-cylindrical brake element made of an elastic material, wherein the at least one brake element surrounds at least a portion of a non-rotatable bearing axis guided by the latch body, and that the at least one brake element is movable relative to one of the two friction surfaces. If the trap base body is pivoted in the housing, the one friction surface, which has the brake element, slides along the second friction surface.
  • the first friction surface can be formed either by the falling body or alternatively by the non-rotatable bearing axis, wherein the arrangement of the brake element on the non-rotatable bearing axis is preferred.
  • the trap body has a control cam for the friction brake.
  • a control cam is a device which allows a regulation of the braking force as a function of the pivotal position of the trap body.
  • the braking force of the friction brake can be controlled and varied during an opening movement or closing movement of the case main body. This is particularly advantageous if the braking action of the friction brake is to act preferably at the end of the closing movement of the Fallengrund stresses.
  • such an arrangement allows a fast opening movement of the falling body, since only a reduced braking effect is triggered by the friction brake.
  • the cam allows a temporally short closing movement of the Fallenground phenomenas, since the braking effect of the friction brake acts only at the end of the closing movement of the Fallenground phenomena.
  • This embodiment is advantageous because the installation of the friction brake has no effect on the security and ease of use of the door opener.
  • control cam interacts directly with a spring-loaded brake means.
  • spring-loaded brake means can also control the extent of the braking effect in the interaction of the control cam with the spring-loaded brake means particularly well and reliably.
  • the cam can be designed such that at the end of the closing movement, the spring force on the braking means increases sharply or the spring-loaded braking means is compressed by the control cam amplified.
  • the control cam can be designed in various ways. For example, rail-like guides can be arranged in the door opener. However, the use of countersunk in the falling body cams has proven particularly useful. In addition to the simple production of such cams, such an arrangement is characterized by the particularly high operational reliability. Variations in the braking force of a control curve sunk into the case base body can be achieved here, for example, via the variation of the distance from the wall of the control curve.
  • the two opposite walls can converge V-shaped, so that the engaging in the control cam brake element engages the Fallengrund stresses in a narrower area at the end of the closing movement and the braking force by friction Bremsiatas is caused on the wall portions of the control cam.
  • the frictional force in the voltage applied to the wall regions of the control cam side regions of the brake element can be significantly increased.
  • the control cam is integrated into a sliding groove, wherein the projecting into the sliding groove brake element runs in a pivoting movement of the Fallengrund stresses along the sliding groove.
  • the integration of the control cam in a sliding groove thus enables the combined use of the control cam for guiding the spring-loaded braking element and for controlling the braking force.
  • the sliding groove is integrated in the case base body.
  • the sliding groove thus ensures, on the one hand, that the braking element moves exclusively in the path predetermined by the sliding groove on the trap base body and does not act arbitrarily and uncontrollably on the trap base body.
  • an adjustment of the braking force by the formation of the sliding groove is possible.
  • the control takes place via the bottom of the sliding groove.
  • the friction brake has a triggering device for controlling the braking force during an opening operation and during a closing operation of the latch base body.
  • triggering device is to be understood as meaning all devices which control a regulation of the braking force as a function of the pivoting direction of the falling body in the opening or closing direction.
  • the triggering device comprises a spring-loaded pressure piece, which has in its tip region a brake element which engages in a falling body-side control cam, i.
  • a triggering device is combined with a control cam.
  • the spring-loaded pressure piece is arranged in such a way that it acts at an angle ⁇ 90 ° to the cam in the closing direction of the Fallengrund stresses.
  • This special arrangement has the consequence that the braking force exerted by the brake element on the latch base body is greater during a closing movement of the latch base body than during an opening movement of the latch base body.
  • This arrangement is preferred, since in this way the braking force can be regulated particularly well both as a function of the direction of movement and as a function of the pivoting position of the trap base body.
  • Viscosity brakes in the context of the invention are brake types whose braking effect is due to the viscosity of a brake fluid.
  • the braking agent is ultimately the component of the viscosity brake, which is responsible for the development of the braking effect. Viscosity brakes are characterized by their simple structure and high resistance to wear.
  • the brake means of the viscous brake is arranged in a region between the rotationally fixed bearing axis and the trap base body.
  • the braking means acts directly on the trap body.
  • the viscous brake has a cavity-like storage area by storing the brake means between the bearing axis and the trap body. This cavity may be distributed to one or more subregions which lie between the rotationally fixed bearing axis of the trap base body and the trap body. The effect of the viscosity brake can be controlled particularly well by varying the viscosity of the brake fluid used.
  • a reservoir may be provided in the door opener, which has a brake fluid reservoir.
  • the braking means is a high-viscosity grease.
  • High viscosity fats are comparatively inexpensive and available in high variability in viscosity. In this way, by varying the viscosity of the grease used, the braking effect of the viscous brake can be adjusted.
  • a viscosity brake in which the braking means fills a hollow cylindrical space between the bearing axis and the case main body.
  • the effect of the viscosity brake can be controlled in addition to the variation of the brake fluid used also on the variation of the extent of the brake fluid space between the bearing axis and Fallengrund emotions. Hollow cylindrical brake fluid spaces between the bearing axis and the latch body have proven to be particularly well for the realization of the visbreaking brake.
  • a further embodiment of the door opener according to the invention is characterized in that the latch base body forms a transmission with at least one damping element, wherein the latch base body for coupling with the at least one damping element has at least one functional area, which is in mechanical engagement with the at least one damping element, and wherein the axial length of the functional area corresponds to a maximum of 90%, preferably ⁇ 50% and particularly preferably ⁇ 10% of the axial length of the trap base body.
  • the functional area of the trap base body is the part of the trap base body which is responsible for transmitting the braking effect of the damping element to the trap base body. Accordingly, the functional area for this purpose, for example, teeth which are in mechanical engagement with a gear, which is in functional communication with a damping element. It has been shown that a small functional area on the trap body works particularly reliably, since varying friction losses of the transmission, which can lead to malfunction of the door opener, are particularly low here.
  • a recess on the latch base body is present, which is designed to engage with a transmission element.
  • the recess is formed toothed, so that a gear as a transmission element can engage in the recess.
  • the damping element such as a rotary damper or a centrifugal brake on.
  • the damping element and the trap base body are thus adjacent to each other with respect to the pivot axis of the trap body or the damping element is operatively connected via the gear with the trap base body frontally. In this way, it is possible to obtain a door opener with a transmission brake, which also has a particularly low overall depth. This is particularly advantageous in areas where the depth available for installing the door opener is comparatively low.
  • the at least one damping element is a centrifugal brake.
  • Centrifugal brakes are preferred because they develop and regulate their braking force as a function of the speed of movement of the trap body. The faster the trap body moves, the higher the braking force of the centrifugal brake. In this way it is ensured that an increased braking force is available at an increased speed of movement of the trap body and thus the noise reduction during operation of the door opener is particularly reliable.
  • rotational dampers or air dampers can be used.
  • the air dampers used in this case which have a movable plunger running in a trachea, typically have a check valve, which is filled with air when opening the trap, so that the trachea is filled with air. When snapping back the trap, the plunger compresses the air in the trachea, which is controlled by a valve, which is for example the check valve, can escape.
  • the door opener additionally has a latching means, which is triggered by a positioning of the latch base body in the closed position and stabilizes the latch base body in the closed position.
  • Detent means in this context thus additionally increase the positioning of the case base body in a specific pivot position, preferably in the closed position of the case main body.
  • Corresponding latching means are, for example, spring-loaded pressure pieces which are pressed into corresponding recesses in the closed position of the latch base body.
  • the holding force triggered by the latching means must now also be overcome.
  • such a depression is arranged on the fallen body, since the comparatively bulky detent mechanism of, for example, locking bolts and spring loading can be arranged easier in the area surrounding the trap body of the door opener.
  • the locking means is integrated in the braking means. This is possible, for example, by a depression of the sliding groove into which the braking means engaging in the sliding groove falls into the end of the closing movement of the falling body.
  • the arrangement of additional locking means in the door opener according to the invention moreover, the possibility to use return springs, which have a comparatively weak spring force. Return springs are responsible for the pivoting of the case base body from the open position into the closed position and are tensioned by the opening movement of the latch base body. Weak spring forces of the return springs lead to a slowing down of the restoring movement of the falling body, with which the noise when striking the fallen body is already effectively mitigated. However, it is necessary here to reinforce the positioning of the trap body in the closed position in order to prevent the risk of undesired movement of the trap body in the opening direction. This is possible by the additional arrangement of locking means.
  • the FallengrundME has at least one elongated recess which is parallel to the pivot axis of the Fallengroundianus that the at least one locking means comprises a pressure piece, and that engages the at least one pressure piece in the at least one recess in the closed position of the Fallengroundianus.
  • the additional stabilization of the Fallenground stressess is particularly pronounced in the closed position by the locking means. Due to the parallel arrangement of the elongated recess to the pivot axis of the case main body is ensured that the pressure piece over the entire axial length of the case base body acts evenly.
  • the door openers 1 (a to w) further have a control mechanism (not shown) and a drive (not shown), usually in the form of an electromagnet, via which a pivoting of the Fallengrund stresses (100 to 108) against the mediated by the Federbeetzleyung 50 Spring force in the housing 2 (a to w) in to release a in the door opener 1 (a to w) protruding latch can be triggered.
