DESCRIPTION

Drive handle made as a steering bar with lever arms that have a coconut structure

The invention relates to a drive handle for a door lock. The door has a stationary door frame with a door leaf supported thereon in a movable manner and preferably made as a hinged leaf with a stop. The door is preferably a door in an emergency and rescue path and, therefore, the drive handle is a panic drive handle.

The drive handle has a drive bar that is made as a driving bar and pivotally supported in a support device consisting of two support devices. The drive bar has at its first end a first lever arm and at its second end a second lever arm. The first support device is assigned to the first lever arm and the second support device is assigned to the second lever arm, such that in the first support device it is pivotally supported with its free end the first lever arm and in the second support device the second lever arm is pivotally supported with its free end. In their mounted position, the support devices are arranged in the door such that their support axes are aligned with each other forming a common horizontal support axis and that the drive bar is arranged horizontally pivotally around said horizontal axis. .

DIN1125 describes panic door closures with a horizontal drive bar for emergency and rescue doors. It distinguishes between the type A bar drive with so-called drive bars that are pivotally supported on the door leaf around a horizontal axis, and the type B bar drive with a pressure bar that is also mounted horizontally on the door leaf, but which is slidably supported perpendicular to the plane of the door leaf. In the case of the present invention, it is a drive handle with a so-called drive bar that is pivotally supported on the door leaf around its horizontal axis, that is, a type A bar drive.

The handles DE9116412U, DE8328207U or GB2445948A disclosed drive handles for door locks of the type mentioned at the beginning.

The invention aims at perfecting a drive handle of this type with a pivoting drive bar on the door leaf around a horizontal axis, so that it can be manufactured simply and is easy to assemble, which has High stability and resistance during use and aesthetically advantageous.

The invention provides four alternative ways of solution based on a common idea, namely, to realize the lever arms of the drive bar, that is, the handle bar, with a structure of shells. The essential thing is that the support housing made in the lever arms for the support tree of the support device and the support housing for the actuation bar, which is also made in the lever arms, are formed by means of shell parts . Each lever arm is composed of at least two pieces of shell, namely a first piece of shell and a second piece of shell. In preferable embodiments, these two pieces of shell are exclusively provided to form the lever arm. But embodiments are also possible in which the lever arms are composed of several pieces of shell, especially also embodiments in which one or several intermediate bodies are arranged inside the lever arm and the shell parts are respectively arranged on the outside, specifically, wrapping the intermediate body or bodies. In all embodiments, the lever arms are made respectively as a composite body, in particular, using the at least two pieces of shell. The term "shell piece" means that the pieces designated by the shell piece respectively form on one of its sides a section of the outer side of the lever arm, that is to say that they have on one side a surface that forms at least one section of the outer surface of the piece of shell. Generally, the shell pieces are flat pieces. The pieces of shell can be made on its outer side convexly in the broadest sense, and on its inner side concavely in the broadest sense. But this is not mandatory. Basically, there are also possible embodiments of shell pieces that have any shape. The essential thing in the so-called coquilla pieces is only that on one side they have an outer surface that forms a section of the outer surface of the composite body.

Claims 1 to 4 indicate the four alternative ways of solution. Subordinate claims 5 to 15 refer to advantageous embodiments that may optionally be performed in the same manner in all four ways of solution.

This means that in this solution No. 4, the first piece of shell has at one end a partial housing for the support shaft and at its other end a partial housing for the drive bar. The second piece of shell is made correspondingly, that is to say that it also has at one end a partial housing for the support shaft and at its other end a partial housing for the drive bar. Therefore, both the support housing of the support shaft and the support housing of the drive bar are formed respectively by two partial housings that are respectively made in the first piece of shell and in the second piece of shell. When the two pieces of shell are assembled forming a composite body, they constitute respectively a composite support housing for the support shaft, which completely encloses the circumference of the connection area of the support shaft and a composite holding housing that correspondingly completely encloses the circumference of the connecting end of the drive bar.

In the following, embodiments that can be optionally provided, in particular, in the four ways of solution are explained.

It may be provided that the first piece of shell and the second piece of shell can be attached to each other in a separable manner forming a composite body. A threaded connection device and / or a retention connection device can be provided for the separable connection.

In preferable embodiments it may be provided that the first piece of shell and the second piece of shell are arranged in the composite body lying directly on the other.

In especially preferable embodiments, the composite body constituting the lever arm is composed exclusively of the first piece of shell and the second piece of shell. But embodiments are also provided in which an additional shell piece or several additional shell pieces or one or more intermediate bodies between the shell pieces are provided. The intermediate body can be made respectively as a single piece body or as a multi-piece body.

Particularly advantageous are embodiments in which the first piece of shell and the second piece of shell form sections of its outer side with the entire outer side, that is, the entire outer surface of the composite body.

In preferred embodiments, it may be provided that in the composite body constituting the first lever arm and the second lever arm, the first piece of shell and the second piece of shell are adjacent to each other by their edges, at least by sections , forming a joint, the joint being made as a longitudinal joint that runs in the direction of the longitudinal extension of the lever arm. In a preferred variant, in these embodiments it may be provided that the first lever arm and the second lever arm have the longitudinal joint respectively on sides oriented towards each other.

In preferable embodiments, one of the shell pieces can also cover several sides at the same time as a screen. In this case, it may be provided that the cross section of the first wing and / or of the second wing is made transversely angled to the longitudinal extension of the shell piece, one of the wings being made in such a way that it covers or that at least largely covers one side of the lever arm on the side opposite the other lever arm. The elbow can be made as a right angle in cross section. But it can also have, for example, more than two angled wings, for example, being made in a U-shape seen in cross-section. According to the invention, it is provided that the support device has a support body preferably made as a support housing. The support shaft is rotatably supported within the support body. The composite body constituting the lever arm can be connected to one end of the support shaft, so that the support shaft engages axially non-rotatably in the support cavity. The support cavity can be made in a composite way by the single coquilla piece or by several coquilla pieces.

The drive handle is therefore a handle with a horizontal driving bar in which the connection of the lever arm ends to the support device assigned respectively in the support shaft rotatably supported there can be axially made in the shaft of support. This means that, preferably, the steering bar can be connected according to the so-called axial concept. But embodiments of the steering bar radially connected to the support shaft are also possible, that is, connected according to the so-called radial concept.

The lock can be made as a built-in lock or as an overlap lock. Therefore, embodiments are possible in which the support device is made in such a way that it can be coupled to a recessed lock located inside the sheet. For this purpose, the support device can drive the nut of the lock, by means of a conveyor non-rotatingly coupled to the support shaft, if necessary, through an intercalated connecting element, for example, a pivot of connection plugged non-swivel into the lock nut. Correspondingly, the support device can be attachable to an overlapping lock.

a front view of a door leaf, on whose inner side a drive bar is mounted and on whose outer side a door handle is mounted.

In the exemplary embodiments shown in the figures, it is respectively a drive bar fitting for a door, preferably for a door in emergency and rescue ways. The embodiments shown in the figures are of a very similar structure. Identical or identical operating components are designated in the figures with the same reference signs. The drive bar hardware is designated in the following description also as drive drive bar or drive bar device.

The drive bar handle of the embodiments of the figures is made according to the nomenclature EN 1125 as "operating bar". According to the standard, it is a type A bar drive. The type A drive bar - the so-called drive bar - has a horizontal pivot axis, around which the drive bar can pivot when operated by hand.

As shown in Figure 1a, the drive bar 1 is supported on the door leaf TF through a support device 2 located on the left side and a support device 2 located on the right side. The drive bar 1 has at its ends respectively a lever arm 1h, so that it has the shape of a U-bracket. The free ends of the lever arms 1h are supported on the pivoting support devices 2, 2. around a pivot axis XA. The hardware, that is, the drive bar device, is mounted on the door leaf such that the drive bar 1 and, therefore, the pivot axis XA are oriented parallel to the plane of the door leaf, specifically, horizontally. By pivoting the drive bar 1 around said horizontal axis XA by pressing it down by hand, the lock mechanism disposed within the door leaf, to which the drive bar device is connected, is actuated in the direction of opening. The lock mechanism is disposed within the door leaf directly below one of the support devices 2 and connected through a connection device arranged in the support device 2. The action of the drive bar device, including the connection device 3, on the lock mechanism is described in more detail below.

In the embodiments shown, the drive bar 1 has at its two ends respectively a lever arm 1h, 1h arranged in a non-rotating manner. The free end of each lever arm is non-rotatably connected to a support shaft 2a located on the exit side. The support shafts 2a are oriented respectively parallel to the drive bar 1. They protrude outward from the corresponding free end of the lever arm on the side opposite to the drive bar 1. The support shaft 2a is respectively supported in the device support 2 assigned, in particular, the left support tree 2a on the left support device 2 and the right support tree 2a on the right support device 2.

In the embodiments shown, the connection to the drive bar 1 to the support devices 2, 2 is a so-called axial concept connection. That is, for the connection of the lever arm ends in the support shaft 2a of the assigned support device 2, an axial connection pipe of the support shaft 2a engages in a cavity at the free end of the lever arm. Variants of embodiment are possible in which the connection of the lever arms 1h is carried out respectively radially in the support shaft 2a, the remaining embodiment being the same.

As best seen in Figures 1b and 1c as well as in Figures 2a and 2b, the support device 2 is formed respectively by a support body 2k. The support body 2k is U-shaped in cross section. It has a support plate 2p from which U2u wings protrude upwards perpendicularly. The U 2u wings have support housings aligned with each other. The support housings are traversed by the support shaft 2a assigned respectively, such that the support shafts are supported respectively with their ends in the support housings assigned on the U 2u wings, rotatably around the XA axis. As can be seen in Figures 1b and 1c, one end of the support shaft 2a is inserted directly into the support cavity and rotatably supported therein, and the other end of the support shaft carries a support bushing 2b supported from rotating form on the support shaft 2a and inserted non-rotatably in the assigned support housing.

On the support shaft 2a, an arm spring 2s is respectively supported, which, as shown in Figure 2b, is supported by one end on a stop bolt on the U 2u wing and which with its other end supports a lever drag 2m fixed to support shaft 2a. The non-rotating connection of the support shaft 2a to the lever arm 1h of the fixing bar 1 is carried out through a hexagon, as best seen in Figures 1b and 1c. The hexagon doubles in the support housing of the lever arm.

For the transmission of the pivoting movement of the support shaft 2 to the lock mechanism not shown in the figures, as can be seen in the representation to the right of Figure 1b and in the central representation of Figure 1c, a bolt of 3K coupling with a 3m drag connected in a non-rotating way. The 3k coupling bolt engages in a lock nut not shown in the figures, which is part of the lock mechanism mounted inside the door leaf. The lock nut constitutes a rotating housing of the lock mechanism. It is arranged in such a way that the coupling pin 3k can be inserted axially aligned. For non-rotating coupling, the drive pin has a square. The lock nut propels the lock mechanism by the fact that the coupling bolt 3k is rotated when the drive bar 1 is operated. Between the support shafts 2a and the coupling bolt 3k a gear is arranged which during the rotation of the support shafts 2a causes a rotation of the coupling bolt 3k. The gear is made in such a way that the 2m non-rotating lever dragger on the support shaft 2a and the non-rotating 3m drive on the coupling pin 3k act together, that is, the 2m lever drive drives the 3m drive, while the drive bar 1 is pivoted down by hand operation. During this, the spring of arms 2s is tensioned. It also serves to push back the pressure bar under the action of the spring 2s after being operated.

In the embodiment shown, the lock is preferably made as a concealed lock hidden inside the door leaf. The lock pin acts in conjunction with a strike made in the stationary door frame or in an adjacent passive leaf. In modified embodiments, the lock can also be made as a lock mounted superimposed on the door leaf. The pin controlled by the drive bar can act in conjunction with a striker mounted superimposed on the stationary door frame. The lock may preferably be integrated in the drive bar device, for example, in a support housing.

Figure 5 shows a door leaf 17 on whose inner side a drive bar handle 1 is mounted and on whose outer side a door knob or latch 10 is mounted. The drive bar handle 1 is a drive bar, that is, a type A drive bar, in particular, made according to the embodiments of figures 1 to 4. This is a driving bar in which the left and right lever arms of the drive bar are respectively connected axially to the horizontal support shaft of the assigned support device, that is, an embodiment of the so-called axial concept.

The pivot axis XA of the drive bar 1 which therefore constitutes a so-called driving bar is represented in Figure 5. It runs perpendicularly to the plane of the drawing. The knob or latch 10 that is

mounted on the outer side of the door leaf TF is also only schematically represented. The essential thing is that the X axis of the door knob or latch 10 is arranged at the same height above the ground at which the pivot axis XA of the handle bar runs and to which the XN axis of the nut of the nut is also arranged. the recessed lock mounted on the door leaf Tf. Advantageously, in this exemplary embodiment it is provided that the fixing of the operating bar 1 is carried out in the perforation pattern of the door handle or door knob 10 mounted on the outer side of the door leaf.

In the embodiments shown in the figures, the support device 2 of the drive bar device is mounted on the door leaf through an adaptation plate 5. The adaptation plate 5 is arranged between the support plate 3p of the support body 3k and the upper side of the door leaf TF, as best seen in Figures 2b and 3b. In figure 4, the adaptation plate is represented as an individual piece.

The adaptation plate 5 has a central passage opening for the coupling pin 3k. In the foregoing, the passage opening is called the connection opening. In the mounted position, said passage opening of the adaptation plate 5 is arranged aligned with the passage opening of the support plate 2p, in particular, such that the central axes of the passage openings are aligned between yes.

The essential thing is that the adaptation plate 5 has fixing holes 5f provided for fixing to the door leaf TF. The fixing holes 5f are made as countersunk holes, so that the fixing screws can engage flat with their screw head. In the representation in FIGS. 2a and 3a, the fixed fixing screws are not shown in the fixing holes 5f. The fixing holes 5f in the adaptation plate 5 are made in a first perforation pattern that is identical to the perforation pattern of the fixing holes in the door leaf TF. The perforation pattern of the fixing holes in the TF door leaf is standardized in standardized doors. The adaptation plate 5 is designed with the perforation pattern of its fixing holes 5f in accordance with the corresponding perforation pattern of the door leaf.

The support plate 2p instead has fixing holes 2f that are arranged in a second pattern of perforations. In the mounted position, these fixing holes are aligned with threaded pivots 5g protruding from the adaptation plate 5 upwards.

The second perforation pattern, that is, the fixing holes 2f on the support plate 2p, form in the exemplary embodiments depicted the perforation pattern of so-called elongated rosettes. The first perforation pattern that is made in the TF door leaf is in the exemplary embodiments represented the perforation pattern of so-called round rosettes. The fixing holes of said first perforation pattern are arranged side by side in a horizontal line. In contrast, the holes of the second perforation pattern are arranged in a vertical line between them. The distance between the holes of the second perforation pattern is greater than the distance between the holes of the first perforation pattern. As shown in the figures for the embodiments shown, the vertical joint line of the holes of the second perforation pattern crosses the horizontal union line of the holes of the first perforation pattern in a cross arrangement, the point being located crossover in the center of the adapter plate 5 and the support plate 2p superimposed, in particular, in the center of the housing openings that receive the coupling bolt 2k.

As can be seen in Figures 3a, 2b, 3b and 4, in the case shown, the fixing holes 5f are arranged in opposite lateral marginal areas of the adaptation plate 5, specifically, in areas that are not covered by the support plate 2p of the support device 2, which in the mounted position lies on it. Therefore, in the mounted position, the fixing holes 5f and the fixing screws inserted therein are accessible from the outside. Figures 2a and 3b show the fixing holes 5f without fixing screws inserted.

The fixing holes 2f on the support plate 2p of the support device 2 are also accessible in the mounted position. They are arranged in the area of the two ends of the support plate 2p between the two U 2u wings of the support body 2k. Figures 2a and 3b show how in the mounted position the threaded pivots 5g of the adapter plate 5 pass through the fixing holes 2f of the support plate, the threaded joint being established respectively through a nut screwed on the free end of the threaded pivots 5g.

In figures 3a and 3b a cover cap 6 is placed on the support device 2. The cover cap 6 covers the complete support device 2 and the adaptation plate 5 located below. For this, the cover cap 6 has a special shape that in particular is such that it is made in the form of a hat or cap with an upper head section that covers the support device 2 and a lower broadening section that covers the plate of adaptation 5, including the lateral areas of the adaptation plate 6 protruding from the support plate 2p.

In the exemplary embodiments shown in the figures, the drive bar handle has a special construction structure characterized by the shear structure of the lever arms 1h. In the

Examples of embodiment shown, the lever arms 1h are composed of two pieces of shell 1h1, 1h2. A support cavity for the non-rotating housing of the support shaft 2a is made in the shell piece 1h1. The support cavity has been made as a closed cavity which, as a socket housing, non-rotatably houses the connecting end of the support shaft 2a. Closed cavity means that the edge the cavity has circled, that is, encloses the circumference of the connecting end of the support shaft 2a. In the case shown, said support housing has been made with a cross section complementary to the cross section of the connecting end of the support shaft 2a, in the specific case represented, respectively as a cross section with a hexagonal contour.

In the assembled position, the other shell piece 1h2 is located on the shell part 1h1 as a covering forming a composite body constituting the lever arm 1h.

At the opposite end of the support housing ha, the overlapping 1h1, 1h2 shell pieces form a holding cavity hb to accommodate the drive bar 1. To do this, in the two shell pieces 1h1, 1h2, in the corresponding final section a half hb1, hb2 of the holding cavity hb is made. As can be seen in Figures 1b and 1c, the holding cavity hb has an elongated cross section. The drive bar 1 has a complementary cross section to it, so that in its mounted position it is held non-rotatably in the housing hb. The assembly is preferably carried out in such a way that the drive bar 1 is inserted with its end in the clamping part of the shell piece 1h1 and then the shell piece 1h2 is placed on the shell piece 1h1 and through The threaded joint is tensioned between the two pieces of shell 1h1 and 1h2. In the exploded representations of Figures 1b and 1c, a screw is provided for each lever arm. To make the threaded joint, the screw is inserted with its threaded rod butt into a through hole in the 1h1 shell piece, and the screw end is screwed into a threaded hole made in the 1h2 shell piece.

In the case represented in the figures, the piece of shell 1h2 is made respectively as a coating. The piece of shell presents transversely to its longitudinal extension a cross-section that is angular and is composed of two wings arranged at right angles to each other. In the mounted position, the upper wing lies on the upper side of the 1h1 shell piece. The side wing covers the side of the lever arm, specifically, the outer side opposite the drive bar. Said wing also covers the outer front side of the clamping housing in which the end of the drive bar 1 is inserted. In this way, the lever arm receives on its outer side opposite the drive bar 1 a closed covering formed for the 1h2 shell piece. The shell piece 1h2 thus covering the outer lateral surface of the corresponding lever arm extends over the upper side of the lever arm from the lower end to a part of the upper end of the shell part 1h1 having the cavity of support. In this way, in plan view from above, the lever arm is covered mostly or practically completely by the 1h2 shell piece.

The two lever arms have on the inner sides oriented towards each other respectively a longitudinal joint formed by the longitudinal edges of the shell pieces 1h1 and 1h2, adjacent to each other in this area.

The exemplary embodiment of the handle bar handle with handle bar, shown in the figures, can be mounted on the door leaf TF using the adaptation plate 5, as explained. The hole pattern of the adapter plate 5 allows the support device 2 of the drive bar handle to be mounted on the pattern of the TF door leaf. In the case shown, the hole pattern of the door leaf is made as a hole pattern of a round rosette, that is, two holes in a horizontal hole row. The hole pattern of the adapter plate 5 corresponds to said hole pattern. The support plate 2p integrated in the support device 2 of the drive bar handle has its own hole pattern which in this case is the hole pattern of a vertical rosette, that is, two holes in a row of holes vertical. The drive bar handle with the support device 2 with the support plate 2p integrated with the hole pattern of the vertical rosette can be made as a standard version of the drive bar handle. For mounting the support device 2 on the door leaf TF, the assembler then inserts respectively the adaptation plate 5 that has the hole pattern corresponding to the hole pattern of the door leaf. It is advantageous if a series of different adapter plates with a different hole pattern respectively are available. Then the adaptation plate that presents the pattern of holes matching the hole pattern of the door leaf must be chosen respectively.

Alternatively, it is also possible that the selection of the adaptation plate 5 and its installation in the support device 2 are already carried out within the framework of manufacturing, in order to manufacture different versions of the drive bar handle with a device support with a specific hole pattern respectively. For this, a manufacturing module may be provided in which the support device 2 and the adaptation plate 5 respectively constitute separate components. The component of the support device may be made as a single standard component existing only in one version, while the component of the adapter plate 5 may be contained in different versions in the manufacturing module. The different versions

from the adaptation plate 5, they differ respectively in terms of the hole pattern. For the manufacture of the drive bar handle with a particular hole pattern, the support device component 2 and the appropriate version of the adapter plate component are combined, such that in the manufacturing framework, the The corresponding adapter plate is installed inside the support device or in such a way that the hole pattern of the adapter plate is accessible to mount the support device on the door leaf through the fixing screws.

It is also possible to make a manufacturing module in such a way that the component of the support device 2 does not have any support plate 2p with its own hole pattern, but that the support device 2 presents, instead of the support plate 2p with hole pattern, only a support area located at the bottom, on which the adaptation plate 5 can be mounted in the manufacturing frame. In this case, the adaptation plate 5 is made as a component in different versions, differentiating the different versions in that they have a different hole pattern. By applying a corresponding version of the adapter plate 5 on the support device 2 available as a unit component, different versions of the support device 2 can then be made according to the version of the adapter plate 5 in the manufacturing framework . The adapter plate 5 could be mounted inside or on the support area of the support device, for example by welding or other joint connection. The support area, located at the bottom, of the support device 2 can already be prepared in such a way as for such a connection, for example, as a frame located at the bottom or as a bottom plate with a corresponding cavity in the area where The adapter plate 5 has the holes of the fixing hole pattern.

As explained, the exemplary embodiments shown in the figures are type A drive bars, that is, called drive bars that can be pivoted about a horizontal axis of rotation for the drive. However, modified embodiments are also possible in which the drive rods are made as type B drive rods (see DIN EN 1125), that is, called pressure rods that for the drive can move perpendicularly to the plane of the leaf as a linear sliding movement. The assembly of these modified embodiments with the type B drive rod can be carried out, in terms of mounting holes of a particular hole pattern, possibly also with an adaptation plate, in a manner comparable to that shown in the figures.

The type B drive bar support devices may have a perforation pattern corresponding to the type A drive bar handle support devices, which are shown in the figures. They can have separate support plates with a pattern of holes for the fixing screws. But the support plates can also be integrated in the support device as a continuous bottom plate with a left end section and a right end section of the bottom plate in which fixing holes are made with the corresponding hole pattern. Correspondingly, on this support plate one or more adaptation plates may be arranged in the final section or a common continuous adaptation plate, or the support plate or the support plates may be replaced by corresponding adaptation plates or complement each other by applying the adaptation plates to obtain through the adaptation plates the hole pattern or the hole patterns, through which the support device can be fixed on the sheet by means of the fixing screws.
