Description

TITLE

Canister and door sealing system

TECHNICAL FIELD The present invention relates to an automatically operable canister bar and door seal system having such a canister bar.

STATE OF THE ART

From EP 1 308 590 a combination of a channel latch with an automatically lowerable door seal is known. For this purpose, the door seal has a through opening, which is penetrated by a locking bolt of the channel bolt. The door seal is actuated by a shutter button projecting laterally when closing and opening the door leaf. The channel latch is independently lowered and raised by means of a manually operable lever.

Furthermore, automatically lowerable channel bars are known from the prior art. Thus, US 4,445,717 discloses a canister with an automatic release when closing the door. For this purpose, a nose is present, which projects the lateral end face of the door leaf and which is connected via a toggle lever with the locking bolt. The bolt is lowered counter to a spring force down. When opening the door, the bolt is raised again due to the spring restoring force. This device also has a safety mechanism in case of misalignment of the locking bolt. If the bolt comes to rest next to the locking recess when closing the door, the multi-part bolt is pushed together against a second spring force. In US Pat. No. 6,409,231, there is also a provision for misalignment, in which case the bolt is raised in the event of a misalignment, as a result of which a compression spring arranged on the toggle lever is tensioned. A similar arrangement is also disclosed in US 4,005,886.

US 5 004 277 discloses a slot along which a vertical tie bar can move to compensate for misalignment.

PRESENTATION OF THE INVENTION

It is an object of the invention to provide an automatically operable canister with a bridging of the actuating mechanism in the event of misalignment, which is relatively easy and inexpensive to produce.

This object is achieved by a channel latch with the features of patent claim 1 and a door seal system having the features of patent claim 13.

The inventive automatically operable Kantriegel has a mounting rail for fastening the Kantriegels in or on a door leaf, an actuating mechanism and a locking bolt with a longitudinal central axis. The actuating mechanism comprises a triggering element for automatically displacing the locking bolt from a starting position to a locking position and a return spring for returning the locking bolt from the locking position to the starting position. The canister also has an automatic lockup which automatically bridges the actuating mechanism upon misalignment of the latch bolt to prevent complete lowering of the latch bolt to the latching position. The actuating mechanism has a displacement element on which the locking bolt rests with a driver, wherein by movement of the displacement element of the locking bolt can be brought into the locking position and wherein the displacement element can be brought by means of the return spring together with the overlying driver and the locking bolt in the starting position. The locking bolt is relative to the driver to the displacement element in the direction of the longitudinal center axis displaceable, wherein the bridging is effected by this displaceability.

The locking bolt is thus lowered when the sliding element shifts down. In the case of an opposing force, e.g. in malposition of the locking bolt, it remains in its position, even if the sliding element continues to move down. When raising the sliding element this takes the locking bolt back to the starting position, should the locking bolt are in an intermediate position.

A misalignment of the locking bolt occurs, for example, when no or a wrongly placed locking recess is present. A malposition is also present, for example, when the locking recess is designed to be too shallow compared to the bolt length and thus the bolt can not penetrate deep enough into the trough.

Preferably, the displacement element forms a bearing surface which is displaceably penetrated by the locking bolt and on which the driver rests. Preferably, the support surface has a passage opening which is displaceably penetrated by the locking bolt. This arrangement is easy to assemble and it can be used differently shaped locking bolt.

In a preferred embodiment, the return spring is a compression spring, wherein the displacement element presses on this return spring. This minimizes the number of parts needed.

In a preferred embodiment, the displacement element is U-shaped and has an upper and a lower leg. The lower leg is slidably attached to a stop surface of the mounting rail and the upper leg is formed longer than the lower leg and slidably penetrated by the locking bolt. This is a simple way to allow the double function of the displacement element, ie actuation of the locking bolt and clamping the return spring, with the least possible effort. Preferably, the displacement element is a pressure plate, which acts on the compression spring. Thanks to this arrangement, the height of the channel bolt can be minimized. In particular, the trigger element of the actuating mechanism may be the uppermost element of the channel latch, with the exception of the mounting rail. In addition, thanks to the pressure plate assembly of the can-tie is simplified.

In a preferred embodiment, the actuating mechanism comprises a toggle having a first leg or arm and a second leg or arm pivotally connected to the first arm, the first arm being provided with the trigger member projecting from the mounting rail, and the second arm is operatively connected to the displacement element. This allows for optimal power transmission and minimizes space requirements. The second arm may be fixed or releasably connected to the displacement element. Preferably, it is only loose. Preferably, the mounting rail has a front plate for resting on a front side or a side surface of the door leaf. It can also be recessed. The locking bolt is preferably arranged so spaced relative to this front panel, that the toggle between the longitudinal center axis of the locking bolt and the front panel is located. The toggle lever is thus designed so small that the locking bolt can move in the direction of its longitudinal central axis past the toggle lever upwards. This also minimizes the overall size of the channel latch.

Preferably, the return spring is spaced from the longitudinal central axis. Preferably, the return spring between the mounting rail and locking bolt is arranged. Thanks to this arrangement, the locking bolt can be arranged offset to the mounting rail, without the total space requirement of the channel bolt thereby significantly increase. The offset takes place in the direction perpendicular to the longitudinal central axis. A small design of the channel latch is particularly welcome in modern architecture, as the use of a small channel latch does not significantly affect the flexibility in the design of the door.

This arrangement of the locking bolt and the return spring simplifies cooperation with a door seal, in particular an automatically lowered Drop-down seal. The locking bolt can also be combined with other types of door seals, for example with manually operated lowering seals or with sliding seals. Since the locking bolt spaced through the door seal passes through the door front end of the seal thanks to its lateral displacement, this frontal area of the door leaf can be sufficiently sealed with the door closed. The erfmdungsgemäße channel latch can also be used without Absenkdichtungen.

In a preferred embodiment, the channel bar further comprises a force transmission spring, which acts with a first end on the locking bolt and acts with a second end on the displacement element. This power transmission spring serves to at least partially transmit the lowering force acting on the sliding element when the triggering element is activated to the locking bolt. If the locking bolt encounters an obstacle during lowering, the power transmission spring first presses the bolt further downwards. A small or with little force displaceable obstacle can be overcome by the bolt. This is particularly advantageous when using the can seal with a seal to overcome frictional forces between elements of the seal and the latch bolt during lowering. However, if the obstacle can only be overcome with increased force, the bridging engages and the locking bolt stops and thus shifts relative to the sliding element, which is lowered further downwards. Such larger obstacles are, for example, the above-mentioned misalignments of the bolt.

Preferably, the force transmission spring surrounds the locking bolt, wherein the force transmission spring rests with a first end on a side opposite the driver side of the displacement element at the latter and rests with a second end on a latch bolt surrounding, fixedly connected thereto bearing surface. Preferably, the force transmission spring is a compression spring. This simplifies the installation of the door seal system and minimizes the size of the system. Preferably, the return spring and the force transmission spring each have a longitudinal axis which are spaced and parallel to each other.

In a preferred embodiment, the mounting rail has a first Guide member and the driver on a second guide member which is engaged with the first guide member. The locking bolt is linearly displaceable along its longitudinal central axis when bridging the actuating mechanism by means of these two guide elements. This guide is advantageous in all erfmdungsgemässen embodiments of the channel latch. In particular, when used with a door seal, it is useful, since here too the channel bar can not move transversely to the longitudinal direction due to the parts of the seal to be passed.

The spring force of the return spring can be selected independently of the spring force of the power transmission spring. In particular, relatively light springs can be used.

The door sealing system according to the invention has a door seal and a channel latch, wherein the door seal has a seal housing and a sealing element and wherein the seal housing and the sealing element have a passage opening for the passage of the locking bolt. The door seal preferably has a carrier rail with a sealing element arranged thereon, wherein the carrier rail together with the sealing element is automatically lowerable and raisable with respect to the seal housing. Preferably, the lowering and raising of the sealing element is independent of the operation of the locking bolt.

Further embodiments are given in the dependent claims.

DESCRIPTION OF PREFERRED EMBODIMENTS

The figures show a erfmdungsgemässes door seal system with an inventive channel latch and with a door seal. Such door seal systems are commonly used in multi-leaf doors. Of the Can latch is preferably arranged in the inactive leaf, ie in that door leaf of the two-or multi-leaf door, which usually remains closed or must still be separately fixed so that the mehrflügelige door remains closed. The Kantriegel is arranged on the lock side, so the other wing, the wing, facing. in the solution according to the invention, the channel bar is raised when the aerofoil is opened. Thus, the inactive leaf can be moved. This door sealing system is suitable for all types of multi-leaf doors, especially for fire or smoke protection doors.

The door seal in this example is a mechanically automatically lowerable door seal. It is attached to a lower end face or in an end groove of a door leaf, for example screwed. Such door seals usually serve as protection against light transmission from one room to another, as sound insulation and as protection against draft. Such door seals are known, for example, from EP 0 338 974. When used in Minergiehäuser®, the gasket typically has an air passageway for air passage from one building space to the adjacent space.

As can be seen in FIGS. 1 and 2, the door seal has a seal housing 1 with a carrier rail 3 held therein. Housing 1 and rail 3 are preferably made of an aluminum profile. Both are preferably U-shaped, wherein the housing 1 is open at the bottom and the support rail 3 is preferably designed to be open at the top. On the support rail 3, a one-piece or multi-piece sealing element 2 is fixed, which preferably consists of an elastomeric material, such as silicone.

The support rail 3 can be raised and lowered together with the sealing element 2 relative to the seal housing 1. For this purpose, a non-visible, mechanically automatically activated lowering mechanism is present, as it is also known from the prior art. For example, EP 0 509 961, DE 19 516 530, DE 35 26 720 and DE 34 27 938 disclose such lowering mechanisms. The activation is preferably unilateral. The seal is preferably for this purpose on a front side a triggering element in the form of a spring-loaded actuating rod before, which at Closing of the door leaf is present on the side door frame and is thereby pressed in. The rod is connected to a power transmission rod which extends in the upper region of the housing 1. In the housing, one or more leaf springs are further held, which are fastened with their respective first end to the power transmission rod and with its respective second end to the housing 1. A central region of the leaf springs is fastened to the carrier rail 3 in each case. If the actuating rod is pressed in, the leaf springs are pressed together and the carrier rail 3 is lowered. The sealing member 2 is sealingly on the floor and closes the gap between the underside of the door leaf and the floor. If the door is opened again, the leaf springs are relieved again and the support rail 3 is lifted together with the sealing element 2 again.

It is of course also possible that the inventive channel lock is used with a door seal, which has another mechanically automatically activated lowering mechanism. Likewise, only a sliding seal can be arranged in the housing 1, which is not raised and lowered relative to the housing. Furthermore, it is possible that a magnetic seal is arranged in the housing 1 or that the seal is electrically activated. The inventive channel bolt has a housing, here called mounting rail 4, for attachment to or in an end face of the door leaf, not shown here. Preferably, it is attached to a lateral end face in the lower or upper end region of the door leaf. The mounting rail 4 is preferably a U-shaped rail, which is designed to open the door. It is preferably made of steel. It can for example be fastened by means of a screw 42 on the door leaf.

At a lower end of the mounting rail 4, a mounting plate 41 is present. It is preferably formed integrally with the remaining mounting rail 4. It rests on an upper surface of the seal housing 1. In the mounting plate 41, a through hole 411 in the form of a slot is present. This opening 411 is in the mounted state of the channel bolt on a through hole 10 of the housing rail 1 and is preferably formed substantially larger than a lower end of a locking bolt 6. An upward in the door leaf protruding screw 45 passes through the mounting plate 41. By means of this screw 45, the seal housing 1 can be attached to the door leaf.

In the front, frontal region of the mounting rail 4, a U-shaped mounting bracket 44 is present. This engages with a leg in the mounting rail 4 and with a second, parallel to the first leg legs in the housing rail 1. This bracket 44 thus connects rail 4 and housing 1 in their front area together. The slot 411 and the bracket 44 allow easy installation of channel latch and seal.

The inventive channel bolt also has an actuating mechanism 5. This comprises a trigger element 50, which passes through a passage opening of a front plate 40 of the mounting rail 4 and this projecting. The triggering element 50 can be configured in different forms, as the examples in FIGS. 5 to 7 show. Thus, according to FIGS. 5 and 6, it may be formed asymmetrically and, in the direction of movement of the inactive leaf, have a bevelled or even curved sliding edge 501 when closing this inactive leaf. However, according to FIG. 7, it may also be formed symmetrically with two oppositely inclined sliding flanks 501, which terminate in a common point. The channel latch shown here is mechanically activated by the trigger element 50 is pressed when closing the inactive leaf or the pommel or by other external force. If the channel latch is electrically operated, e.g. by using a motor, the trigger element does not have to protrude. In this case, the triggering element may be a switch which can be activated manually and / or by means of a signal.

The trigger element 50 is, as can be clearly seen in Figure 3, part of a toggle lever 51. This is located behind the front panel 40 and comes to rest in a corresponding groove of the door leaf. The trigger element 50 forms the extension of a first leg 510 of the toggle lever 51. This first leg 510 is pivotable about a pivot axis 512 fixedly connected to the mounting rail 4. At which the triggering element 50 opposite free end of the first leg 510 is a second leg 511 pivotally connected thereto. An end of the second leg 511 opposite this connection is operatively connected to a displacement element 52. The sliding element in this example is a pressure plate 52. Preferably, said end of the second leg 511 loosely rests on this pressure plate 52 and can roll on it. A corresponding roll axis is provided with the reference numeral 513. A stop pin 53 serves as the upper stop for the first leg 510, wherein the leg 510 is present at the stop pin 53 both in the case of the release rail 4 protruding release element 50, ie in a starting position, as well as fully depressed element 50, ie in a locking position.

The pressure plate 52 extends approximately perpendicular to the front plate 40 and is held within the mounting rail 4 relative to this movable. Preferably, it is U-shaped, wherein a first upper leg 520 is formed longer than a second lower leg 521. The lower leg 521 is preferably slidably with its free end against a rear abutment surface 43 of the mounting rail 4 and thereby becomes in its vertical Movement led

The lower leg 521 presses on a first end of a return spring 55, here a compression spring. This return spring 55 extends parallel to the front plate 40 of the mounting rail 4 and is at its second end on the mounting plate 41.

The upper leg 520 has a Durchgangsöffhung 522 (see Figure 9), which is penetrated by the locking bolt 6. The locking bolt 6 has a longitudinal central axis a, which extends parallel to the longitudinal axis of the return spring 55.

The locking bolt 6 has an upper area, the bolt neck 60, and a subsequent lower area, the bolt body 61. The bolt neck 60 preferably has a round cross section and is held displaceable relative to the pressure plate 52 within the passage opening. The bolt neck 60 is fixedly connected to a driver 8, which is arranged above the upper leg 520 of the pressure plate 52 and rests loosely in a starting position on this. The driver 8 is preferably formed as a plate. The bolt neck 61 has a Außenge winch 63, which meshes with an internal thread of the driver 8. As a result, the length of the bolt 6 projecting downwards from the pressure plate 52 can be adjusted in its length. Thus, the caning bar can be adjusted according to the lowering stroke of the door seal and the distance between the bottom B and bottom of the door. This adjustability is shown in Figure 3 with the circular arrow.

The driver 8 has a protruding nose 80, which engages in a vertically extending gap 46, formed in the abutment surface 43 of the mounting rail 4, and guided in this gap 46 is displaceable. Gap 46 and nose 80 thus form a groove / sliding block connection and form an anti-rotation lock for the locking bolt 6. This can be seen in Figure 8.

At the upper free end of the bolt neck 60, a radially outwardly projecting ring 62 is arranged. It serves as an upper stop when the height of the locking bolt 6 is adjusted by means of the thread 63.

In the lower region of the bolt neck 60, i. below the pressure plate 52, a first stop ring 70 for a power transmission spring 7 is present. Also, this power transmission spring 7 is preferably a compression spring. It surrounds the bolt neck 60 and is at the bottom of the upper leg 520 of the pressure plate 52 at. For this purpose, a second stop ring 71 may be attached to the power transmission spring 7. Preferably, the force transmission spring 7 is biased.

The cross section of the bolt body 61 may be round, rectangular, oval or square, as shown in FIG. It can also have a different shape. He passes through not only the passage opening 411 of the mounting plate 41, but also through holes in the Absenkdichtung. The seal has for this purpose both in the housing as well as in the sealing element 2 and optionally in the support rail 3 depending on a through hole 10, 20, which are aligned with each other and with the slot 411 of the mounting plate 41. It is also possible that a guide element is arranged in the Absenkdichtung to guide the locking bolt in its movement relative to the seal. This is already known from EP 1 308 590. The bolt body 61 is in this example already in the raised state, ie in the starting position, the sealing member 2 below before. This need not necessarily be the case, it can also end within or even above the seal or it can be aligned with the lower edge of the sealing element.

The mode of operation of the channel lock according to the invention and of the door seal system according to the invention will be described below with reference to FIGS. 9 to 11:

Reference B denotes a building floor and L is a locking recess, i. a recess in this bottom B, in which the locking bolt 6 is to engage when closing the door leaf.

In Figure 9, the situation is shown with the door open, i. the starting position. At least the wing is open. The illustrated channel bar and the door seal of the standing wing are in the raised state. The actuator 50 is the front plate 40 before. Also, the actuating rod, not shown, of the seal is in the longitudinal direction of the seal before the housing 1. This rod usually protrudes from the other, not shown front end of the seal out. The toggle 51 is unloaded in Figure 9 and the return spring 55 relaxed. The pressure plate 52 is thus in its upper position. Also, the power transmission spring 7 is unloaded and the locking bolt 7 penetrates though the seal; its lower end is, however, spaced from the bottom B and the locking recess L.

In the situation according to FIG. 10, the active leaf (not shown) and the inactive leaf are closed, ie the locking position is shown. The actuating rod Absenkdichtung is pressed by contact with the door frame and the sealing element 2 is lowered. It lies sealingly on the floor B. The trigger element 50 of the channel bolt is also on the door frame, not shown, and is thereby pressed. The toggle 51 is activated and now pushes the pressure plate 52 down. The return spring 55 is tensioned. The driver 8 and the locking bolt 6 lower together with the pressure plate 52 from. In this case, the driver moves 8 guided along the gap or the guide groove 46 and serves together with the power transmission spring 7 as rotation for the locking bolt 6. The locking bolt 6 engages in the locking recess L, without lying on the bottom of the trough. The inactive leaf is now locked.

If the aerofoil or the inactive leaf is opened again, the external force is lost to the triggering element 50. The return spring 55 relaxes again and pushes the triggering element 50 outwards. The pressure plate 52 is raised and raises thanks to the driver 8 and the locking bolt 6 back to its original position. In addition, regardless of the discharge of the operating rod, the support rail 3 is raised with the sealing element 2. That is, the starting position according to Figure 9 is reached again.

However, if there is no or too little depression in the bottom B when the upright wing and the wing are closed, then the bridging or securing is used. This situation is shown in FIG. The bridging or securing is essentially formed by the displaceability of the locking bolt 6 relative to the pressure plate 52. When the trigger element 50 is closed when closing the standing wing from a stop, e.g. pressed the toe, first lowered the locking bolt 6 together with the pressure plate 52 from. However, as soon as it rests on the ground or on another massive obstacle and the spring force of the force transmission spring 7 is too low, the locking bolt 6 stops in this position while the pressure plate 52 continues to lower. The pressure plate 52 thus distances itself from the driver 8. The carrier rail 3 with the sealing element 2 can nevertheless be lowered, since the actuating rod and the corresponding lowering mechanism of the seal function independently of the channel latch.

When opening the wing or the wing, the seal lifts again. In addition, the return spring 55 of the channel bolt is relaxed here, whereby the pressure plate 52 is raised. As soon as she has reached the driver 8, which has remained standing in an intermediate position, she takes him and thus also the locking bolt 6 upwards into the starting position. The trigger element 50 is again swung out of the front panel 40. The Krafitübertragungsfeder 7 is not mandatory. However, if it is present as shown in this example, the force transmission spring 7 acts when lowering the pressure plate 52 as a force-transmitting member on the locking bolt 6. If the locking bolt 6 encounters a surmountable obstacle or if it has to overcome lateral frictional forces when penetrating the seal, it will to move down as long as these forces are smaller than the spring force of the power transmission spring 7. In Figures 9 and 10, the power transmission spring 7 is thus relaxed or slightly biased. In Figure 11, the bottom forms an insurmountable obstacle for the bolt 6. Thus, the force transmission spring 7 is now compressed by the further displacement of the pressure plate 52 and thus stretched. If the door is opened again or the pressure plate 52 is raised, the force transmission spring 7 can also relax or return to its starting position. Furthermore, this spring 7 serves as a rotation for the bolt. 6

The inventive channel latch and the sealing system according to the invention can also be used on an upper end side of the door. In this case, the prestressed power transmission spring 7 is mandatory and provides a counterforce to the weight of the locking bolt. The terms used in the description and in the claims, such as "lifting", "lowering" and the like thus also refer to this type of use, wherein "lifting" as pulling the sealing element into the housing rail and "lowering" as an extension of the sealing element from the housing rail to be understood in a sealing position. The inventive channel lock is particularly suitable for use with door seals, preferably with Absenkdichtungen. LIST OF REFERENCE NUMBERS
