Description

The invention relates to a gate according to the preamble of patent claim 1.

Gates with a movable between an open position and a closed position Door leaves are used, for example, for closing garages, factories or warehouses. In many cases so-called sectional doors come for reasons of space savings used, the door leaves of a plurality of in the direction of movement behind each other arranged and extending perpendicular to the direction of movement hinge axes comprising joints interconnected panels. Thereby the movement becomes of the door leaf by means of guide rail arrangements and on the individual panels mounted guide rollers, the guide rail assemblies usually two guide rails with vertical sections, between which the Door leaf is received in the closed position, and over arcuate sections of it connected, horizontally extending sections, between which the door leaf in the open position is included. In many cases, such gates are with locking arrangements equipped with which the door leaf are locked in the closed position can. In this case, locking arrangements can be used, the one with a Biasing device in the direction of a locking position biased locking element have, which under the action of the biasing device automatically in the Locking position reaches as soon as the door leaf reaches the closed position. Such arrangements are given for example in EP 0 924 371 A1.

However, the use of such bolt traps has particularly in garages and hall doors, with which relatively large bushings are closed, as problematic proved, because the door leaves of these gates by design relatively much Game in the guides or guide rail arrangements have, so that by appropriate Force a movement of the door leaf transverse and perpendicular to Torblattebene is possible, whereby the locking of the door leaf are released in the closed position can.

In view of this problem, EP 0 073 964 discloses a door with a locking arrangement proposed the type described above, in which the actual locking function and securing the corresponding locking element in the locking position separated by using a suitable retaining element are. In the locking arrangement described in the cited document is a in shape a Schnepperscheibe educated and attached to the door leaf rotary latch, the for locking the door leaf in the closed position with a respect the frame of the door stationary arranged locking bolt cooperates. For this purpose, the rotary latch is rotatable about an axis of rotation parallel to the door leaf plane mounted on the door leaf and has one of its outer edge in the direction of the Rotary axis radially inwardly extending indentation. In this indentation attacks the Locking bolt in the course of the closing movement of the door leaf and causes so a rotation of Schnepperscheibe or the rotary latch in the locked position, in which the locking pin receiving indentation approximately in the horizontal direction runs, so that the locking bolt no longer without rotation of the locking plate can be removed from the indentation and so together with the locking disc of a Counteracts opening movement. To secure the locking plate in this locking position is in the known locking arrangement in the form of a Schnepperbolzens formed holding element provided. This Schnepperbolzen can when reaching the locking position by a displacement in the direction of its longitudinal axis in one provided in the locking plate recess are retracted so as to twist to prevent the locking disc and to secure the lock. Will the Schnepperbolzen pulled out in the direction of its longitudinal axis from the recess of the locking plate is a twisting of the bolt disk urid a movement of the door leaf of the Closed position possible in the open position.

In the known locking arrangement of Schnepperbolzen is over a Schloßstrange such a rotatable about a perpendicular to the door leaf extending axis of rotation Coupled rotary handle that by turning this knob a movement of the Schnepperbolzens along the longitudinal axis can be effected. In this arrangement there is a risk that the coupling of the Schnepper bolt to the rotary handle damaged and thus the entire locking assembly becomes unusable. Furthermore, it is at This arrangement requires that the rotary latch is twisted by hand to unlock to effect the locking arrangement, which in particular when using the known Gates in warehouses is problematic, where the warehouse workers often do not have a hand to operate the rotary latch free.

An arrangement may be used to eliminate the defect first described be in which the Schnepperbolzen without using a lock rod and a Turning handle directly between the holding position and the release position along its in the Usually parallel to the door leaf extending longitudinal axis is moved. But also with this Arrangement is required in many cases difficult unlocking by hand. Furthermore, gates are given according to the preamble of claim 1 in US 6,089,626.

In view of the above-described problems in the prior art, the invention is the object of a goal with a locking arrangement of the initially described To provide type, which on the one hand, even when used in large feedthroughs reliable lockable and on the other hand can be easily unlocked, at the same time a high mechanical stability of the locking arrangement is ensured.

According to the invention, this object is achieved by the characterizing part of the claim 1 specified development of the known door solved. Advantageous embodiments The invention are set forth in the dependent claims.

In the context of the invention, it has proven to be particularly useful when the cooperating with the locking element part of the holding element on the one hand the pivot axis and the pedal on the other hand, the pivot axis is arranged.
The locking arrangement according to the invention gates unlocking by foot, which not only an operation is also possible when the user has no more hands free, but also the otherwise required annoying bending over to effect unlocking is avoided.

To obtain an automatic lock when reaching the closed position of the Torblattes it has proven to be particularly favorable when the locking element of the inventive gates similar to the Schnepperscheibe the known locking arrangement by a rotational movement about a preferably parallel to the pivot axis of the Retaining element extending axis of rotation between the locking position and the release position is adjustable, wherein the locking element is a disc with a from whose edge has in the direction of the axis of rotation extending indentation, in which in the Closed position at least one further locking element of the door is added. This indentation in the locking position as well as the corresponding Indentation of the known Schnepperscheibe approximately in the horizontal direction or outgoing extend obliquely upward from the edge of the locking plate.

In the context of this invention is also thought, the locking plate similar to the locking arrangement described in EP 0 073 964 B1 rotatable on the door leaf to be fastened so that they cooperate with, for example, attached to the frame Locking bolt can cause a lock. As structurally particularly favorable However, it has been proven when the locking plate is rotatably mounted on the frame. If the gate serving for guiding the Torblattbewegung guide rail assembly and at least one on the one hand taken in the guide rail assembly and on the other hand via a fastener, such as a roller axle rotatably mounted on the door leaf has fixed roller, a lock in this case without using a additional component can be realized when the fastener or the roller axis is used as an additional locking element, which in the closed position is received in the recess of the locking plate.

The retaining element of the locking arrangement of the door according to the invention can constructive particularly simple to run when it is a form-fitting in the holding position engaging in the locking element or the locking plate and preferably with respect to the pivot axis approximately circumferentially extending pawl having. For this purpose, the locking plate is expediently with at least one other Receiving the pawl serving indentation provided, preferably in the Locking position approximately in the circumferential direction with respect to the pivot axis of the holding element extends. As a result, in a particularly reliable manner a safer form-fitting Engagement of the pawl in the locking plate allows.

Especially with regard to a possible retrofitting of existing gates It has proved to be particularly advantageous when the locking element and / or the Retaining element as well as the guide rail assembly attached to a frame of the door are. To obtain an automatic lock when reaching the closed position the door leaf may be a first biasing means urging the retaining element in the holding position be provided. This first pretensioner can be particularly easy in Be executed a torsion spring, which is supported on the one hand on the holding element and on the other hand is fixedly mounted with respect to the pivot axis.

To obtain a reliable operation of the gate according to the invention, it has Furthermore, proven to be favorable when a the locking element or the locking plate in the release position urging second biasing means is provided to to ensure that the further locking element, such as the roller axis at the closing movement automatically comes into engagement with the locking element. These second biasing means may be formed, for example in the form of a weight, with the locking element or the bolt automatically under gravity is transferred to the release position. When using a rotatably mounted locking disc the weight is expediently at the for receiving the further locking element serving indentation opposite side. To further Securing a reliable operation of the door according to the invention has it proven to be advantageous if the locking element preferably formed in the form of a locking plate in the release position, the pawl of the holding element at least Having partially receiving receptacle, wherein the locking element also at in the recording recorded pawl against the biasing force of the first Biasing device is adjustable from the release position into the locking position. In this way, with the help of the pawl and the example in the form of a recess Shallow depth recording formed a locking of the locking element causes in the release position, the use of relatively low forces can be overcome by the pawl against the biasing force of the first biasing means is lifted out of the receptacle.

When using a equipped with a pedal holding element can a Overturning of the retaining element can be reliably prevented when the pedal at least one at release of the opening movement approximately parallel to the bottom of the with Gate closed space extending and preferably adjacent to this floor Has contact surface.

An undesired movement of the holding element or pedal can be prevented when the pedal is at least one to guide a release of the opening movement having pivoting movement serving guide surface. To this Purpose, it has proved to be particularly favorable when the pedal in the form of a U-profile with two sections perpendicular to the pivot axis extending legs having one attached to a frame of the door, and preferably also in shape a U-profile formed with two perpendicular to the pivot axis extending legs Console overlaps. To obtain a pivoting movement of the holding element or pedal enabling attachment of these components can be a perpendicular to the pivot axis extending legs of the pedal and / or the console enforcing fastening bolts be used. In this case, the first biasing device between a the perpendicular to the pivot axis extending legs of the console and a parallel to be arranged legs of the pedal to be arranged. Especially with regard to Retrofitting existing gates, it has proven to be particularly favorable if the at least one locking element or the locking plate also on the console is attached.

As already explained, the door leaf is expediently in the manner of a Sectional with a plurality of in the direction of movement of the door leaf in a row arranged and extending perpendicular to the direction of movement hinge axes having Joints formed interconnected panels.

As can be seen from the above explanation of gates according to the invention a suitable for producing such gates inventive locking arrangement at least one between a locking position in which it may cooperate with counteract a further locking element of the opening movement of the door leaf can, and a release position in which the opening movement is released, adjustable Locking element and at least one between a holding position in which it is the locking element the locking position holds and a release position in which there is a Adjustment of the locking element releases movable support member and is substantially characterized in that the holding element by a with a on the holding element attached pedal releasable pivoting movement from the holding position in the Release position is transferable.

The illustrated in the drawing embodiment of the invention consists essentially of a door leaf formed in the manner of a sectional door with a plurality of in Direction of movement of the door leaf successively arranged panels, of which in the Drawing only the bottom in the closed position panel 10 is shown, a frame 20, a fixed to the frame guide rail assembly 22 and a total of 30th designated locking arrangement. To guide the movement of the door leaf is, as in The following example is explained for the bottom panel, a leadership role on each panel appropriate.

In the panel 10 shown in the drawing, this guide roller 16 is over an angle profile 12 and a roller axis 14 about a parallel to the door leaf extending Rotary axis rotatably mounted on the door leaf and on the other hand in the guide rail 22 recorded. The locking arrangement of the illustrated in the drawing Embodiment of the invention comprises an axis of rotation extending parallel to the door leaf 42 rotatably held on the frame 20 locking element in the form of a locking plate 40 and one about a parallel to the door leaf extending pivot axis 52nd pivotally mounted on the frame retaining element 50. The locking plate 40 has a extending from its edge in the direction of the axis of rotation 42 extending indentation 47, which is widened at the edge and in the locking position shown in Fig. 1 extends horizontally. In this indentation 47 is in the illustrated in Fig. 1 Locking position, the roller shaft 14 of the roller 16 was added. From the in Fig. 1 shown closed position, the door leaf can only be in the direction of the open position move when the locking plate 40 at the same time in the course of movement of the Roller axis 14 in the direction of the open position about the rotation axis 42 in the release position is rotatable in which the roller shaft 14 slide out of the indentation 47 can. Such a rotation of the locking plate 40 is prevented by the holding element. For this purpose, the holding element has a relative to the pivot axis 52 approximately in the circumferential direction extending pawl 56, which in the locking position shown in Fig. 1 is received in a corresponding indentation 46 of the locking plate 40. On the opposite with respect to the pivot axis 52 of the pawl 56 side is the Holding element equipped with an executed as a pedal actuator 58.

As can be seen particularly clearly in Fig. 2, the holding element in the area of the pedal 58 has a section in the form of a U-profile with two perpendicular to Swivel axis 52 extending legs 60 and 62 on. The holding element 50 is as well as the locking plate 40 on a side attached to the frame 20 console 70 attached. In this case, the console 70 also has the shape of a U-profile with two perpendicular to the pivot axis 52, axis of rotation 44 and roller axis 14 extending Thighs 72 and 74 on. As can be seen particularly clearly in Fig. 2, the retaining element 50 with the help of one of the legs 60 and 62 of the holding element 50 and the Legs 72 and 74 of the bracket 70 passing through fastening bolts 54 on the console 70 fastened, wherein between the mutually parallel legs 74 of the console and 62 of the holding member, a gap is formed in which a biasing means 80 is housed in the form of a torsion spring. With this torsion spring 80 is the retaining element is urged in the direction of the holding position shown in Fig. 1. To For example, the torsion spring 80 has an end 82 adjacent to the pedal 58 and a recess the bracket engaging end 84, while otherwise the fastening bolts 54 rotates. As is apparent from Fig. 2 further, is also the bolt disc 40 fixed by means of a fastening bolt 44 to the bracket 70, said fastening bolts 44 passes through the locking plate 40 and the leg 74 of the console 70.

By stepping on the tread 58a of the pedal 58, the retaining element of the in Fig. 1 shown transferred to the release position shown in Fig. 3 be in which the pawl 56 is removed from the recess 46, whereby a rotational movement the locking plate 40 about the rotation axis 42 and thus also an opening movement the door leaf is enabled. In the course of this opening movement, the roller axis 14 arranged on the lower panel 10 of the door leaf roller from the Dented recess 47 and so solved in total from the locking arrangement. With regard to the desired foot operation of the holding element 50, the tread 58a of the holding element 50 at a height of less than 40 cm, preferably less than 20 cm above the bottom of the closed door with the room. To avoid an over-rotation of the retaining element 50, the pedal is at its tread 58 opposite bottom provided with a contact surface 59, which in the in Fig. 3 illustrated release position approximately parallel to the floor with the door closed space runs and expediently rests against this. Furthermore, it becomes a reliable one Operation of the arrangement shown in the drawing favors that the inside the leg 60 of the pedal a guide surface for the pivoting movement about the Pivot axis 52 forms, which rests against the outside of the leg 72 of the console 70, so as to tilt the pedal or holding element about a transverse to the pivot axis 52 extending tilt axis to prevent.

By extending the roller shaft 14 from the recess 47 of the locking plate 40th the latter is transferred to the release position shown in Fig. 3. With the help of one on the the indentation 47 opposite side arranged counterweight 48 is the Locking plate obtained under gravity in the release position, in which the roller axis 14 retracted again in the indentation 47 at the next closing movement can be, with this retraction by the edge extension of the indentation is favored.

To further ensure trouble-free operation of the pipe according to the invention is the locking plate 40 with a in the release position a receptacle for the pawl 56 forming shallow indentation equipped. As shown in Fig. 4, comes Pawl 56 after release of the retaining element 50 in the release position of the locking plate lie in this shallow indentation 49, so that the locking plate 40 with the help the pawl 56 and the retaining element in the direction of the stop position urging Torsion spring 80 is held in the release position. When the roller axle 14 at the next closing movement of the door leaf back into the recess 47 of the locking plate 40 moves in and then moved further down, it results in a rotational movement the locking disc in the direction of the locking position shown in Fig. 1, in whose Course the pawl 56 against the biasing force of the torsion spring 80 from the flat Dent 49 is excavated.

The invention is not limited to the embodiment explained with reference to the drawing limited. Rather, is also thought of the use of locking arrangements, in where the locking plate and / or the retaining element is attached to the door leaf. Furthermore, can a separate locking bolt can be used. Also, the invention is not only related Can be used with sectional doors, but also with overhead doors. It is also thought also the locking plate by means of a corresponding torsion spring in the direction of to pre-load the release order.
