Title: Door stop system

Description

The present invention relates to a door stop system which can be used with all types of doors or with other similar opening systems. In a particular embodiment, the present door stop system can likewise serve as a door hold-open device.

On the one hand, door stops should prevent a door from being moved beyond a certain opening angle, and thus from damaging other installations or an adjacent wall. On the other hand, door stops serve likewise as a protection for mounted floor springs or overhead door closers from turning a door leaf too far. Moreover, door stops are generally executed as prominent compon ents, which are fastened on the flooring or as spacers at the wall behind the door leaf and serve as an abutment for the door leaf, when the desired maximum opening angle is reached.

However, one disadvantage of these known door stops is that, with the door being closed for example, they represent an obstacle for passers-by, that is easily overlooked, and they may therefore cause accidents. This is an important issue particularly in publicly accessible areas.

2003109 PC

DE 203 06 001 U1 discloses a hold-open device for glass doors, in which a catch in the shape of a spring-loaded ball is used for holding the door leaf in the closed condition.

The documents CHB555464 and CH 562 384 AS respectively describe an interlocking device for an emergency exit, in which the interlocking device is equipped with a solenoid, a bolt &and a locking catch. In this case, the free end of the locking bolt carries a roller, the locking catch presenting two chamfers, being oriented in opposite directions. The bolt is not pre-loaded and will not be retracted in the event of a power supply interruption to the solenoid. Such an interlocking device serves for locking exit doors in the closed condition. The bolt does not present any force in a corresponding de-energized condition, and therefore it cam be pushed out of the interlocking position, if a corresponding force is applied to the door in the opening direction, such that the door can be opened correspondingly.

Another device likewise desigmed as a safety locking device including a roller, whichs is situated at a spring- loaded bolt and cooperates with a chamfer, is revealed in

GB 20 512 03 A.

Furthermore, so-called door hold-open devices are known from the state-of-the-art, which are fastened to the door and are latched by foot, once the door reaches the desired

2003109 PC opening width. In this case, a bolt, generally backed with rubber, is pressed against the floor with the intention to constrain the door leaf in that momentary position.

However, such door-hold open devices must be actively s actuated and they do not work very reliably, such that the door, if a corresponding amount of force is applied, can be nevertheless moved beyond the momentary position.

Furthermore, such door-hold open devices have a relatively complex conception, and thus can not be manufactured cost effectively.

On the basis of this state-of-the-art, the object of the present invention is to provide a door stop system, which can be reali zed cost effectively, functions reliably and does not represent an obstacle for passers-by.

The object #s solved with a door stop system according to patent claifmm 1. Advantageous embodiments of the door stop system, in the following simply designated as door stop, which allow the application thereof as a door hold- open device as well, are subject matter of the dependent claims or are revealed in the following description and the embodiment examples.

The present door stop consists of a locking component, a longitudinal guide for the locking component, which guide is formed for being mounted at a door leaf or for being integrated into a door leaf in an orientation, in which the

2003109 PC locking component with the lower end thereof is directed by gravitational force towards a bottom surface under the door leaf, and an element forming a cavity for recess in the bottom surface, which element, at least on one side of the cavity, presents a lateral abutment for the locking component and, on the opposite side, at least a partially rounded or sloped limitation of the cavity. The lower end of the locking component is formed such that the lower end can be moved in a sliding or rolling manner. In this context, the expression door, respectively door leaf is to be understood in a broader sense and includes other than usual doors in a passageway for individuals, such as entry doors to buildings or rooms, likewise similar types of opening elements, such as for example windows, or the like. In the following, in this context, doors in a passageway, which are mounterd above the flooring as the bottom surface, are respectively considered. It is apparent that these explanations, in the above sense, can be transferred to other door species, such that the bottom surface does not necessarily have to be the flooring.

The longitudinal guide with the locking component, which is preferably bar-shaped and can present a round or an angular cross-section like known door hold-open devices, is mounted in the lower front region of the door leaf. Other than being mounted on the outside, the door leaf can integrate the longitudinal guide, such that just the locking

2003109 PC component protrudes somewhat from the lower end of the door. Moreover, the locking component is displaceable and vertically supported within the longitudinal guide, such that, if technically correct mounted at the door leaf, the 5s component will be directed automatically towards the flooring by gravitational force. Of course, for assisting this action, an elastic member, such as a coiled spring for example, can be mounted in the longitudinal guide. The longitudinal guide itself may be formed as a guiding tube, for example, as a guiding rail or have the shape of several guiding rings. The exact embodiment of this longitudinal guide is insignificant in this case, as long as the function thereof, i.e. the guidance of the locking component is guaranteed upon partial protracting and retracting.

An element forming a cavity serves as another component of the present door stop, which element is recessed in the flooring such that it does not project from the surface of the flooring. The element forming the cavity can already be mounted into the flooring when the latter is manufactured or installed or it may be mounted later into the finished flooring, for excample by cutting out the floor. The location of the element can be determined through a supplied drilling template, which matches the dimensions of the locking component. T his element generates an appropriate cavity with an abutment, and, for example, a trigger in the flooring, into which cavity the locking component

2003109 PC penetrates upon opening the door, if the locking component hits the eleme nt that covers the cavity.

The abutment, by means of which the stop function is achieved, can be formed by means of an aimost vertically shaped wall region of the cavity of this element.

The lateral wall on the opposite side is sloped or rounded, such that the door, when being moved into the opposite direction, can be released without expenditure of force.

As an alternative, a plate-shaped element can be foldably attached at the upper limitation of the cavity on this side, which element, upon entry of the locking component into the cavity, folds down against a spring force, which is for example applied by means of a compression spring disposed within the cavity, to form a sloped ramp, intended for the entry and an exit of the locking component.

Upon exiting the cavity, the locking component, when moving along the ramp, can be pushed back further into the longitudinal guide against gravitational force, until it has exited the cavity, and the door can be moved in a usual way.

This element forming the cavity is obviously integrated into the flooring at the appropriate location where the desired opening width of the door will be reached.

The door stop system can be used with pivot doors, such that only one longitudinal guide with the locking component is mounted at the door and two cavity elements are mounted recessed into the floor, on both sides of the door, resp ectively.

Furthermore, both, the

2003109 PC depth of the cavity and the length of the locking component must be adjusted to each other, such that the locking component is still inserted in the longitudinal guide when reaching the bottom region of the cavity.

When using the present door stop, the door is opened in a usual way, without increased expenditure of force, until reaching the cavity in the flooring, which the locking component automatically penetrates, and is stopped at the abutment along with the door. Then, the door can not be opened any further, for example, such that the desired reliable door stop function is achieved. Moreover, no additional element has to be actuated for closing the door, as on account of the sloped or rounded limitation on the opposite side of the abutment, simply a slightly increased force has to be applied compared to the normal movement of the door, for moving the door out of this termiral position. A substantial advantage of the present door stop resides also in the fact that, through possibly complete integration of the cavity element into the flooring, ro stumble blocks are created, which might hinder passers-by or even cause accidents. Therefore, the use of the prese nt door stop offers a considerable advantage, particularly in locations with public traffic.

With the intention of preventing the roller of the lockirg component from running steadily on the flooring, when the :

2003108 PC . N door is moved, for example a swing door describing a quarter circle or a sliding door describing a longitudinal movement, a deactivation and activation of the door stop system and thus of the locking component is suggested.

Thus, the resulting undesired stripes in the floor region are avoided.

A device is provided for activating and deactivating the locking component, which may be integrated within the guiding tube. In this case, it is insignificant, whether the device is integrated into the locking component or into the tube. Such a device substantially consists of a guiding coulisse with a guiding pin guided therein, which is disposed at a connection to the locking component. The connecting element will preferably consist of pretensioned material, such as a laminated spring, for example.

Moreover, the guiding coulisse preferably presents a heart- shaped contour having a slight inclination, such as to assist the characteristic of pretension of the connection to the guiding pin. The construction of the coulisse substantially consists of a lower locking point followed by an ascending pathway, which terminates in an upper saddle point. The saddle point serves as reversal to the movement, whereby on the ascending pathway the guiding pin strives upwards and in the saddle point is redirected to a pathway, which is located below the saddle point. This pathway terminates in

2003109 PC \ N an upper lowest point, which simultaneously represents the position of the retracted locking component. The retracted locking component remains in this position until it is forced out of this point by means of a trigger. With a strict 5s mechanical approach, this trigger is situated within the flooring and is placed where the element forming the cavity is recessed within the flooring. It is conceivable that the element forming the cavity is integrally manufactured directly with the trigger. Thus, it will be guaranteed that accurate distances are observed and no unnecessary scratch marks will be generated on the flooring, if the trigger is recessed in the floor too far in front of the element forming the cavity. The means of first choice as a trigger has proven to be a spherical element slightly protruding from the floor.

If the retracted locking pin passes over this trigger, the locking component, on account of the contact, is pushed even further into the fastening tube. This means that, on account of the pretension of the connection, the guiding pin is pushed upwards out of the lockin g point, and is inevitably pushed beyond a reversal point located adjacent to the locking point. The reversal point is followed by a coulisse pathway having a downwards orientation, which pathway in turn terminates in the lower locking point. This means that, on account of the forced guidance of the guiding pin, the locking component is pressed against the floor, whereby

2003109 PC simultaneously the connection element, ©n account of the resilient action thereof, prevents frorm destruction, if corresponding articles are present behind the trigger on the flooring. Thus, in a normal situation, the roller or the slider 5s provided at the locking component will plunge into the element forming the cavity via the sloped wall and will immobilize the door in this position.

On account of occupational safety regulations, surface mounted door stops are generally not ad missible in public areas. However, such door stop complies with official regulations in each situation. Even for floor cleaning the present door stop offers advantages insofar as cleaning machines do not have to run around any additional obstacles.

Another advantage of the inventive door stop is a simple construction making manufacturing simple and cost effective. In principle, the present door stop may be manufactured from any material or combimed materials and can be attached to or within any species of door opening components. The execution is realized in accordance to the specific dimensions and weight of the door. in another embodiment of the present door stop, in the bottom region of the cavity of the element forming the cavity between the sloped or rounded lateral wall and the vertical abutment, for example a retaining ledge is

2003 109 PC

S11 - provided, which the locking component has to overcome on the way towards and back from the abutment. Through an appropriate embodiment of the retaining ledge, particularly through an appropriate choice of the gradients of the lateral surfaces of the ledge, the required expenditure of forces for relerasing the door, i.e. for guiding the locking component back into the longitudinal guide, can be increased, such that the embodiment can achieve the function of a door hold-open device.

Likewise, the inventive idea of a door stop system can be realized in that, with an arrangement of a modified element forming the cavity, a gap opening of the door, for example for aeration purposes, becomes possible. In stuch case, the element forming the cavity would be provided with two sloped walls disposed on opposite sides, which at the bottom are connected with a horizontal ele ment. In the event the door is then opened, the raised locking component will be lifted on account of the trigger provided at the element forming the cavity in the above described manner, and the locking component is lowered down along the sloped walls into the element forming the cavity.

Retaining ledges are provided at the bottom for allowing reliable positioning of the door, which will achieve holding of the door component. In the event the door is then ope ned further, the locking component will move along the sloped wall out of the element forming the cavity and, due

22003109 PC fo an additional trigger downstream, will return into the rest position, i.e. the retracted position.

Wpon even further opening the above described door, another additional door stop system of the above described species can be used, which will prevent the door from being opened any further.

Obviously, the function as a door hold-open device can be achieved through an additional mechanism at the longitudinal guide, for example, through a screw, which allows for blocking the locking component in the ongitudinal direction, as well as for releasing this blocking.

In this way, the door can likewise be kept in the correspondingly mounted cavity and can only be moved back into the other position (release of the door) through corresponding disengagement, respectively release of the locking component.

According to the invention, realizing a door stop in conjunction with a locking device, which can be adaptively mounted or integrated with the door stop system, is likewise an option. In this case, the locking component can

Ibe moved downwards either by gravitational force or through a corresponding spring element and can be additionally retained in the locked position through an electrical locking. In order to move such door out ©f the locked position, particularly with fire-rated doors, uniocking

2003109 PC can be realized by a corresponding door shunt device. In this case, the door stop, with or without interlocking device, is invisibly mountable within a profile of a door. Moreover, other than this invisible mounting, the mounting particularly on door leaves, which includes an electrical interlocking device, is of course likewise possible.

It is apparent that such doors can be equipped with a door closer or with a drive in conjunction with a sensor. With an - automatic drive, upon the opening process, a blocking of the locking component can be triggered through a corresponding electrical circuit.

While a strict mechanical approach of a door stop system is explained in the above described explanations; however, it is likewise possible to autom ate said type such that, for example, in conjunction with an automatic door drive, both, a gap opening of the door and a certain terminal position opening of the door may be achieved through an automated locking component in conjunction with an element forming the cavity. Instead of the above described entirely mechanical trigger, the angle positions of the door leaf can be measured for this purpose, for example, by means of an incremental sensor. Moreover, the movement of the locking component can be assisted, respectively executed by a corresponding solenoid or electrical motor. It

2003109 PC is obvious that such arrangement can be mounted li kewise invisible within a door leaf.

The present invention will be explained hereinafter on the basis of a variety of embodiment examples, reference being made to the drawings, in which:

Figure 8: like Figure 7, however, in the locked position.

Obviously, the door stop for the attachment at a door leaf, illustrated in the Figures, is to be considered as an example only. This door stop substantially consists of a guiding tube 2, which is mounted to a mounting bracket 1.

The material of the mounting bracket 1 for the attachment at a door leaf 6 is optional. The statics of the mounting bracket 1 will be defined as required. It will be mounted in the lower region of the door 6, such that the guiding axis of the guiding tube 2 extends perpendicularly to the flooring 8.

In the present example, a pin or bolt is employed as a locking component 3, which presents an almost circular cross section, for example, including a longitudinal groove 4. The longitudinal groove 4 serves for protecting the locking component 3 from twisting. For this purpose, a corresponding securing pin 12 or a projection is provided in the guiding tube 2, which pin engages in this groove 4, as can be seen in Figure 1. This securing pin 12 can be employed in a corresponding embodiment, for example as a screw, for blocking, respectively latching the locking component in a cavity 7, such as to realize therewith a door

2003109 PC hold-open device simultaneously. In orme embodiment of the locking component 3 in the shape of a profile rail, respectively a profile, the longitudinal groove 4 can be given automatically through the profiled s hape. A front view s on the mounting bracket 1 including the guide 2 is additionally illustrated on the right hand s ide of Figure 1. In this view, openings 27 for attachment screws, as well as the securing pin 12 for the locking composnent’s 3 anti-twist protection are visible.

A trailing member, in the present case a roller 5, is mounted at the lower part of the locking component 3, by means of which the locking component 3 can roll into the cavity 7. The roller 5, in conjunction with a trigger 19, simultaneously serves for activating and deactivating the locking component 3.

It is evident that the guide or the guiding tube 2, including the locking component 3, can likewise b e integrated into the door 6, such that just the locking component 3 protrudes from the guide, respectively from the door on the lower part.

The element forming a cavity 7, which, for example, can present a round, an oval or as presented, an angular shape, is mounted as an abutment stop fosr the door leaf 6 at a certain opening width in the flooring 8, such that it is flush with the top side of the flooring 8, “with no stumble

2003-109 PC edges remaining. This cavity 7 for the abutrment in the flooring 8 or in other levels may be mounted either when installing the flooring 8 or mounted later and covered by an appropriate rosette. Through activation by the trigger when moving the door leaf 8, the locking component 3 is pushed, on account of the gravitational force thereof, through its own weight, into the cavity of the element 7 untill reaching a vertical lateral wall in the cavity 7, which serves as an abutment 11. The door leaf 6 presents a terminal abutment at this location, which can be provided with a rubber coating or a similarly acting material for ara abutment absorption. By choosing the mounting location of the cavity element 7, the opening position of the door leaf 6 can be precisely determined. For achieving a trouble-free release of the door 6 from this abutment, on the side opposite the abutment, the element 7 presents a sloped ramp 9 or a rounding, which allows the locking component 3 to plunge back into the guiding tube 2 when moving the door 6 into - the closing direction.

Finally, Figure 2 shows in a lateral view the element forming the cavity 7 including the sloped lateral wall 9 as well as the vertical abutment 11, whereby, in this example, an additional retaining ledge 10 for retaining the door leaf 6 in the terminal position is visible at the bottom of the cavity.

The retaining ledge 10 is designed in that retaining the door leaf 6 is guaranteed with a certain wind pressure or

2003109 PC h -18- back pressure; however, a user of the door may easily push the leaf 6 forward during closing.

The lateral wall 9 serves both as an entry slope and as an exit slope.

The abutment of the element 7 can obviously be provided with a corresponding damping element 13 or a corresponding coating or layer, for example made from neoprene, for preventing sharp noise. The element 7 itself may be made from steel, aluminium or plastic material, for example, the roller 5 of the locking component 3, for example, from plastic material . in another inventive embodiment the element forming the cavity 7 can be provided with a flexible cover. Moreover, the cover can consist for example of a plastic material, for example neoprene, being sufficiently dimensioned to allow for normal walking on the cavity. In this regard, the cover would provide the cavity 7 with the correspond protection against atmospheric exposure. For example, such cover, in the middle thereof, can present a central slot to allow the entry of the locking component 3. When the locking component 3 with the roller 5 contacts the cover, the latter would spread apart, such that the locking component 3 can penetrate the cavity 7 without obstruction, until the door leaf 6 is stopped at the abutment 11 directly or at an upstream damping element 13. As this cover is flexibly

2003109 PC designed, the slot will close immediately, once the locking component 3 has left the cavity 7 in opposite direction.

Figure 6 shows a variant of an element formirsg the cavity 7, in which both, a sloped lateral wall 9 and a sloped lateral 5s wall 16 are provided. The sloped lateral walls 9 and 16 converge at the bottom 41. Retaining ledges 10 are placed at the ground 41 for simultaneously locating the locking component 3 such that the slider, respectively the roller 5 provide reliable support for the locking component 3 and thus the door leaf 6 in a rest position. Simultareously, two triggers 19 serving to control the locking component 3 can be integrated into the cover collar 24. In the diagrammatical illustration, it can be seen that a locking com ponent 3 is able to enter such element 7, to pass through it and to exit again. The mode of operation of the triggers will be described later.

In another embodiment, as shown in Figures 3 and 3a, the element forming the cavity 7 can be provided with a cover 14 that can be lowered and is held in the plane of the flooring surface 8 by means of one or seweral spring elements 15. If the locking component 3 penetrates into the cavity 7, the cover 14 is pushed into the cavity 7 by the locking component 3 against the force of the spring, as diagrammatically indicated in Figure 3a. The cover 14 can consist of a flexible plastic material or rubber, for example,

2003109 PC

A -20- or of another material, and, if the locking component 3 leaves the cavity 7, will be moved back into the initial position through the shown spring element 15, in which position it protects the cavity 7 from external influences. In this example, the damping element 13 for damping the locking component 3 at thee abutment 11 is likewise visible.

In this embodiment, the cover 14 that can be lowered is equipped with an articulation on one side that is not illustrated.

The dimensions of the element 7 as well as of the locking component 3 and of the associated longitudinal guide 2 are chosen according to strength requirements.

Figures 4a and 4c show another example for the embodiment of the element forming the cavity 7 of the present door stop system. In this example, a plate-shaped element 21 in the shape of a lid is foldably fastened at the upper limitation of the cavity, which upon entry of the locking component 3 into the cavity 7 folds down, for example against the force of the spring element 15, to form a sloped ramp for the entry and exit of the locking component 3. In this emt»odiment example, a buffer stop 23 is integrated directly into the locking component 3. Such measure allows for reducing the size of the complete element forming the cavity 7. The locking component 3 2s travels over the plate-shaped element 21, which, on

2003109 PC

A -21- account of the forces exerted by the locking component 3, pivots down to the region of the bottom thereof and thus provides entry to the locking component 3 into the element forming the cavity 7 via the sloped plate 21. In this case, 5s the buffer stop 23 abuts at the abutment 11, which is situated within the cavity element 7.

The element 7, at the underside thereof, presents an anchoring plate 29, which is situated within the flooring 8. A borehole 25 for evacuating water that has entered is provided within the anchoring plate 29 and the bottom of the cavity element 7 situated on top of if. Other than through the anchoring plate 9, the cavity element 7 is fastened via a fastening in the ground, having the reference 26. A cover collar 24 (F igure 4c) forms the upper termination of the cavity element 7. Furthermore, the trigger 19, which will be described hereinafter, can be integrated into the cover collar 24.

Figures Sa and 5b depict a modification of the element forming the cavity 7. In this case, an angular element 22 has been used as a closing element for the cover. This angular element 22 consists of a long leg and of a short abutting leg 31. In the rest position of element 22, the long leg forms simultaneously the cover for the cavity 7. The - element 22 presents an axle 30 situated in the region of the long leg, about which the element 22 is rotatably supported

20031-09 PC insid e the cavity 7. The second leg, namely the abutting leg 31, is formed in an angle of about 90° in relatiors to the longesr leg. The abutting leg 31 projects into the cavity 7.

The dimensions of the angular element 22 are designed such that, on account of the position of the axle 30 and the dime=nsion of the abutting leg 31, if not in use, the element 22 cl oses the cavity 7 through gravitational force. However, it is moreover conceivable that a spring element will be used to assist the action. Now, if on account of the locking component 3 upon contacting the element 22 the latter is pivoted into the cavity 7, against the gravitational force of the abutting leg 31 and/or against the force of a spring, which is not illustrated, a descending slope into the element 7 is created simultaneously for the locking component 3. At the end of the slope, the locking component 3 with the buffer stop 23 thereof runs against an abutment 11. The abutting leg 31 forms the limitation for the element 22 in the tilted position, which leg will abut at the wsall region on the opposite side of the abutment 11. If the door is pivoted back into the closing position thereof, the lacking component 3 leaves the cavity 7 in the opposite direction to the entry direction and, on account of the restoring force of the spring element or the gravit ational force of the abutting leg 31, the element 22 is pivoted back into the rest position thereof. Thus, in the rest position, the long | eg of the element 22 reliably closes the cavity 7 .

2003109 PC

As already set forth above, the locking component 3 should not permanently travel, respectively slide over the flooring 8, thus to avoid resulting service marks. Therefore, a device 20 is illustrated in Figure 7, which allows for achieving a pure mechanical lifting and lowesring of the locking component 3 with simple means. Figure 7 shows the retracted position of the locking component 3. The locking component 3 is slidably supported inside the guiding tube 2. In the embodiment example, the device 20 is stationary integrated within the guiding tube 2 above the locking component 3. It should be noted that a reversal is possible, i.e. the device 20 may be provided at the locking component 3.

A. connection 28, which, at the one end, is po sitively and nhon-positively connected to the locking comporent 3 and, at the other end, carries a guiding pin 27, is situated at the locking component 3. The connection is mourted slightly p retensioned, as can be seen in Figure 7 (curv-ed form). A guiding coulisse 32, which almost presents the shape of a heart, slightly turned, is provided inside the device 20. ‘Substantially, the guiding coulisse 32 consiists of the following components, a locking point 38 folloswed by an ascending pathway 37, which terminates in an upper saddle point 34, and a slightly descending patheway on the opposite side of the ascending pathway 37, which terminates in an upper lowest point 33. A slightly higher

2003108 PC h -24 - reversal point 35, which itself transforms into a descending pathway 36 terminating in the locking point 38, is adjacent to the lowest point 33.

In the following, the mode of operation of the guiding coulisse is given in details.

If the door leaf 6 is moved or turned into the opening direction 39 of the door, the roller 5 comes into contact with the trigger 19. The dimension al adjustment between the roller 5 and the trigger 19 is such that the locking component 3 is inevitably pushed upwards within the guiding tube (see Figure 7). Through the connection 28 with the guiding pin 27, the latter is simultaneously pushed out of the upper lowest point ard, on account of the forced guidance thereof, is pushed past the reversal point 35.

Thus the locking component 3, after being shortly lifted, is lowered on account of the subsequent following descending pathway 36, and can plunge into the element 7, like in the already above described manner. This is likewise shown in Figure 8, where the locking component 3, via the element 21 plunges into the element 7 within the flooring 8. Once the locking component 3 has plunged into the element 7, the door leaf 6 can not be moved any further. Simultaneously the guiding pin 27 has reached the lower locking point 38.

2003108 PC a -25-

Then, if the door is supposed to be closed again, i.e. the door is pivoted into the pull direction 40, on account of the sloped position of the element 21, the locking bolt 3 travels upwards on this slope and, through the connection 28, s automatically pushes the guiding pin 27 in the ascending pathway 37 of the device 20. When pas sing over the trigger 19, the guiding pin 27 will simultaneously pass over the upper saddle point 34 and will be guided to the upper lowest point 33 by the subsequent forced guidance. This means that, after leaving the trigger 19, the locking component 3 is slightly lowered and re mains in this retracted position. The above described action would be repeated only upon travelling over another &rigger, i.e. the locking component 3 would be lowered agai.

In the preceding descriptions of the figures for better clarity mainly the door leaf 6, at which the locking component 3 is situated, has not been illustrated. However, it has to be understood that the locking component 3 is mounted to a door leaf.

The above described embodiment of a door stop system is applicable to both, swing leaf doors and sliding doors.

Moreover, it is of no importance if the door leaves are manually or automatically operated. Such. a door stop system in conjunction with a sliding leaf, an automatic sliding door or a manual sliding door would simultaneously

2003109 PC even represent a locking of the leaves, if, for example in the closed position, the locking component 3 plunges into the cavity element 7. Applied transverse forces can not move the locking component 3 out of the cavity 7. With sliding leaves, the locking component would be generally employed at the front edge, namely the closing edge of the leaf.
