DK 162787 B

The present invention relates to a capturing mechanism of the kind set forth in claim 1.

By a known capturing mechanism of this kind (NL disclosure no. 82 02 877), the captive-shaped captive element is pivotally mounted on a carriage slidable within a captive housing. Also attached to this sled is the tensile string. The carriage at the end of the drawstring string turns into a bolt which is passed through the lower end of the catch element housing and which is provided outside the housing with a screw pressure spring which actuates the bolt towards a displacement position extending from the housing. The catch latch supports in the release position against a lower edge about an opening in the catch element housing such that the sled in the resting position of the tensile string of the spring force is pressed downwardly, whereby the spring, due to its rejection at the opening edge of the housing, is swung out of the opening to the catch position. Thus, the catch latch in the release position is not fully retracted to the interior of the housing, the spring for swinging of the catch latch in the locking position is outside the housing subject to soiling and similar functional impairment effects. The catch element housing is attached to the building closure plate and the catch latch is pivotable in the plane of this plate and engages the catch rail 25 which is located adjacent to the plate. The catch rail is thus at a distance from the side edge area of the building opening to be closed by means of the closing plate, which means that the catch rail as a freestanding structural part must be designed in a stable manner. In addition, there is a risk that the trapped closure plate may edge between the trapping bars located on both sides, making it difficult to detach the closure plate from this position.

The object of the invention is to provide a catch mechanism of the kind mentioned at the outset, which operates quickly and safely, is protected from dirt and damage.

DK 162787 B

- 2 - performance and in particular also easy servicing and functional testing.

This is achieved according to the invention in the embodiment of claim 1.

By means of the device of practically all the parts to be moved during a trapping course, in the interior of a housing, the trapping device is first and foremost protected against dirt and damage, and the device is arranged so that the trapping element by extinguishing it the associated tensile string or breakage thereof enters the catch position before the closing blade or door leaf, because of its inertia, moves noticeably away. The 15 spring inserted in this connection is also inside the housing, and it is therefore above all also protected against the fact that its effective spring length is reduced by unintentionally embedded foreign bodies in the spring road.

Basically, the captive element along a translational stretch in the case of string leakage can be transferred from the holding position to the catching position by the spring loaded bolt. In a particularly preferred version, the catch element is designed to be rotatable within the 25 catch latch housed in the housing, which engages an inclined surface provided in the longitudinal direction of the bolt against the bolt located within the housing, so that the bolt rotates the latch outside the housing due to its spring load. the catch position as soon as the spring due to a wire break or the like can work 30.

Furthermore, the spring arranged between the closure blade and the drawbar has the advantage that acceleration of the closure blade produced especially by hand operation is attenuated 35 to the weight equalizer so that the drawstring, specially designed as a rope, cannot spring from the wire drum. For this purpose, so far - 3 -

DK 162787 B

used a special spring arm. Since the catching device according to the invention also fulfills this function, the spring arm which is otherwise located in the same place can be waived.

In a particularly preferred embodiment, the catch mechanism is designed such that the direction of movement of the catch element extends approximately perpendicular to the closing blade plane so that the catch element in the catch position abuts against a catch rail which may advantageously be arranged near the edge of the doorway to be closed. In this way, the forces that occur during captures, under certain circumstances, allow themselves to be easily diverted to the masonry, and the other construction can similarly be carried out more easily. For this purpose, the catch element housing, which at the entrapment displaces across the closure blade, is at least conductively supported on the side facing the catch rail. In principle, the catch device operates over the total distance traveled by the closing blade between an opening position and its inclined position. However, at rocker doors, especially ceiling sliding doors, the forces exerted by the drive and / or weight relief device on the door plate disappear when in the opening position, i.e. that the lower edge is mounted in the region of the arcuate transitions 25 of the guide rails. This real lapse of the leash tension can be utilized to transfer the catch latch from the release position to the catch position without entering into a catch engagement with the catch rail since no catch is required in this area. This has the particular advantage of keeping the catch latch moving. Something similar is achieved at a hand operated door when the door plate goes against a stop in the opening position.

Normally, only one cable breaks, or only a 35 weight equalizing spring breaks, so that the door at separate shaft is unilaterally trapped and can bias. In addition, the door plate performs lateral movement in a certain range of play.

By means of similar wide-dimensioned catch openings, it is possible to ensure that in all these cases no clamping occurs. You often need to open or close a trapped door plate. This is done simply by intervening under the door plate with a forklift or similar and raising it. For the sake of lowering, in a particularly preferred embodiment of the invention, the capture element is allowed to arrest in the release position, e.g. by being held in this position by a screw. In this way, an opening and closing of the door plate is possible. IN

In the normal case, by means of this particular opening, the catch element can be operated in a particularly simple manner by means of a pin or the like for testing the functional ability.

15

The catch mechanism can easily be placed on building locks of the kind that come up. Thus, with existing cable-borne door plate, the cable attachment is only loosened by the laterally extending fixing bolts and the 20 bolts from the captive housing are hung on it, while the cable end is placed to the prison housing and fastened there, which is preferably done at the pivot of the catch. In the case of a motorized door plate, the displacement of the catch element to the catch position can be utilized to operate a supply current switch. In a preferred embodiment of the invention, a second movement occurs at the force of a second spring acting on the catch element after it is triggered by a first spring.

Further embodiments of the invention will be apparent from the subclaims in connection with the exemplary embodiments given in the drawing, which are considered in particular, and the following description of which further explains the invention.

FIG. 2: The same corner area, however, seen in the direction of the wire; 5

FIG. 3; An image of the narrow side of the door plate with intersected catch element housing and the catch latch in release position; FIG. 4: A view corresponding to FIG. 3 and with the catch link in the catch position.

As can be seen particularly in Figures 1 and 2, rollers 3 are attached to the door plate above the roll holder 2, which is 15 embedded in a guide rail 4. Of these roll holders and rollers, there is especially a whole row at a so-called section door. In addition, of course, the parts and structures of the projections in the right-hand edge of the picture envisaged must be imaginatively mirrored in the left-hand edge area of the door panel (not shown). The guide rails are not attached to bracket 5 in the manner shown in the area around the side of the building opening edge. Also attached to the brackets 5 are catch rails 7, which are thus also located in the area around the side of the building opening edge 6, and which can support correspondingly well. As in particular FIG. 1 shows that the catch rails 7 are provided with a series of longitudinal catch openings 8 which are relatively wide, in the present case wider than the opposite side of the catch element housing 10, which is arranged in the edge region of the door plate, as can be seen in FIG. 2nd

At the housing side opposite the catch rail 7, a guide bracket 11 intervenes, so that, as will also be depicted later, the catch element housing 10, which in the catch case 35, displaces across the door plate 1 along its narrow side and with it captive being captive element -fig. 4 - cannot depart in the away direction from the catch-

DK 162787 B

- 6 - rails 7.

FIG. 1 shows, as in Figures 3 and 4, a bolt 12 which, at 13, comes into contact with a fastening bolt 27, 5 whereby 13 can be an eye in a groove. This bolt 12 engages through the lower front side 17 of the housing 10 into its interior. Through the upper front side 16 opposite to this front side, a clamping sleeve 15 is passed through, with which the wire 14 serving as a pulling string is. joined together in a loop thus formed.

The sectional views of FIG. 3 and 4 clearly show the design of the catch element housing 10 and its associated building parts. Within its longitudinal side wall 18 facing the catch rail 7, the housing exhibits a side opening 19 which faces the housing side 20 on which the guide bracket 11 engages supportively. The additional housing walls 21 on the sides, which extend perpendicular to the walls 18 and 20, and of which, because of the house section, only the rear part is seen, 20 holds between them a pivot axis 22 about which the catch latch 23 is pivotally mounted. As seen in FIG. 3, the pivot latch as well as the latch nose are located outside the catch element housing 10 when the catch latch 23, due to a sufficient voltage state in the associated wire 14, is in the release position which represents the normal operation of the intact wire, scheduled working equalizer and the like. . The bolt 12 retained by the eye 13 and the fastening bolt 27 in the lower side region of the door plate engages slidably through the lower front side 17 through a lead-through opening 28. In its end region of the housing, the bolt 12 is provided with a head 29 which is designed so as to width that the side faces of the bolt head are directed to the interior side walls of the housing. Between the inner wall of the lower front side 17 of the housing 10 and the opposite underside of the head 29 is provided a screw pressure spring 32 through which the bolt shaft is passed. Around - 7 -

DK 162787 B

in the coil spring there is provided a sleeve-shaped stop 33, which in turn is supported at one end by the inner surface of the front side 17 and at the other end of the underside of the head 29 facing it. As shown in FIG. 3, the bolt 5 12 is located at tensioned wire 14 with the head 29 in contact with the stop 33, so that the screw pressure spring 32 exhibits its greatest possible compression.

On the bolt head 29 there is depicted a bevel 30 which, with respect to the bevel, fits with an inclined surface 31 against which the bevel 30 abuts and which is formed on the bevel nose 24 in the region of the fang-latch which is above for the pivot axis 22. This system shows fig. 3 at the release position 25 of the catch link.

15

If the wire 14 breaks or loses its tension for other reasons, then the housing 10 shifts downwardly relative to the bolts 12, and thus under the force of action of the compressed and now straightening spring 32, far faster than the initial speed of the now crashed door leaf. In FIG. 4, the mutual position between the fully drawn lines rendered housing 10 and the punctured rendered head 29 of the bolt 12 is shown, that is, by relaxing spring 32, enters this punctured end-point displacement position in the interior of the housing. In this way, the head 29, by means of its bevel 30, presses on the inclined surface 31 of the catch latch 23, so that the longitudinally sliding brings the catch latch in a pivotal motion about the pivot axis 22 with the latch nose 24 engaging the downwardly subsequent catch opening 30 8 on the catch rail 7, as can be seen in FIG. . 4. Thus, in this position, the catch latch 23 is in the catch position 26.

The clamping sleeve 15 for the wire 14 passes through a passage opening 34 in the upper front side 16 of the housing 10, and also slidably longitudinally. The wire loop located in the interior of the housing 10 engages in a bushing ring which forwards

DK 162787 B

- 8 - switches the pivot axis 22, and this with a certain clearance, so that a compression spring 36 which surrounds the wire 14 and its end returned by means of the sleeve 15 5 is arranged between the inner wall of the front 16 and the bushing ring 35 the bushing ring 35 displaces slightly over the pivot axis 22 into the interior of the housing. At the bushing ring 35, an actuator 38 engages an electrical switch 39 with which a drive motor is switched off. Since the screw pressure-spring 32 enclosing the bolt 12 is harder or stiffer, respectively, than the compression spring 36 enclosing the wire 14, the housing 10 first shifts with respect to the bolt 12, so that the catch 23 comes into its catch position 26, then the displacement of the bushing ring 35 makes room for operating the contact 39.

As FIG. 3 shows, the catch latch 23 on its side facing away from the catch rail 7 shows a threaded bottom hole bore 41 which, in the release position 25 of the latch 23 with respect to its entrance opening, aligns with a bore 42 in the housing side 20. By means of one from the outside of the housing Through the screw 42 inserted in the threaded bottom hole bore 41, the catch latch 23 can be retained in the release position, or be returned to it and 25 arrested, respectively, when the door plate after a catch operation is not only to be opened - the catch latch would act as a ratchet - but should also be able to closes, e.g. by means of a forklift, until the defective wire or the fault which results in the weakening of the wire has been repaired.

30

As already mentioned briefly, the catch apertures 8 across the direction of movement of the door plate 1 are very wide and in fact several times the width of the latch 24, so that the gate can be safely captured in any possible lateral movement. A unilateral error, e.g. wire rupture, does not cause clamping of the gate so that it cannot be raised.
