Description

The invention relates to a drive device for a drive rod fitting with a drive housing, which has two housing parts which can be connected to one another, wherein at least one housing part has a drive rod guide, with the features of the preamble of claim 1.

It is known to use drive devices for espagnolette fittings for moving locking elements of a window or door leaf. The drive housing of the drive device is thereby inserted into a pocket of the profile of the window or door leaf. Before inserting the drive housing into the pocket, a drive rod is inserted into the drive rod guide of the drive device, and then the two housing parts are connected to one another.

From the EP 0 440 987 A2 is known a drive rod transmission, which has two housing parts. The connection of the two housing parts is effected by a rivet, which is integrally formed on a housing half and passes through a rivet opening of the other housing half.

The DE 23 45 496 A1 discloses a drive rod transmission having two housing parts. Lugs or projections of a housing part come in notches or recesses of the other housing part to lie. The lugs can be riveted to connect the housing parts together.

The DE 203 13 119 U1 discloses an espagnolette for windows or doors comprising means for longitudinally displaceable co-operation with a drive rod disposed in a housing, the means being coupled to the drive rod via a coupling member, the coupling member being longitudinally guided in the housing, and the coupling member being flattened from a sheet metal portion rectangular section consists.

The GB 2 208 173 A describes a drive rod housing having a plurality of housing parts. The housing parts have through openings which are aligned with one another and which are connected to one another by connecting means. The connecting means are riveted to the housing parts.

From the EP 2 149 660 A2 a drive housing for a drive rod fitting has become known, the housing parts by means of a plurality of latching elements, such as latching hooks and locking lugs, are connected to one another. The necessarily at least partially resilient latching elements can be bent in unconnected state of the housing parts and cancel. Furthermore, the production of the locking elements is complicated due to their shape.

The invention is based on the object to provide a drive device for a drive rod fitting, in which a connection of the housing parts of the drive housing can be achieved in a structurally simple manner.

This object is achieved by a drive device with the features of claim 1.

By the connecting element, which is inserted in the connected state of the housing parts in the recesses of the two housing parts, a secure and firm connection of the two housing parts is achieved. The production of the recesses in the housing parts is very simple. As a connecting element, a pin or the like can be used, which can also be manufactured inexpensively and easily. Furthermore, the housing parts are formed by the avoidance of locking connections and latching hooks in the unconnected state less sensitive.

The drive rod can be used in unconnected state of the housing parts in the drive rod guide. In the connected state of the housing parts, the drive rod is received in the drive housing. The drive housing is therefore preferably designed such that a connection of the two housing parts is provided parallel to the longitudinal direction of the drive rod. To achieve a fixed connection of the two housing parts, the first recess and the second recess are therefore preferably designed such that the connecting element is insertable perpendicular to the direction of movement of the drive rod in the driving rod guide.

The connecting element is preferably insertable from the side facing away from the driving rod guide in the drive housing. As a result, a disturbance of the drive rod movement is avoided by the connecting elements.

A particularly strong connection of the two housing parts can be achieved in that the second recess is formed in a securing projection of a housing part, which is insertable in the connected state of the housing parts in a securing recess of the other housing part.

A particularly secure connection of the housing parts can also be achieved in that in the housing part in which the first recess is formed, a third recess is formed, which is aligned with the first recess, wherein the connecting element by the first and second recess feasible and in the third recess is insertable or can be performed by the third recess. To forcibly separate the two connected housing parts, the connecting element would have to be both between the first and the second Recess as well as between the second and the third recess sheared off. The connecting element thus enables a particularly stable connection of the two housing parts.

The drive housing preferably has a locking projection which can be inserted into at least one locking recess of the connecting element. In a particularly preferred embodiment of the invention, the third recess on the locking projection and the connecting element, the at least one locking recess, in particular at least one continuous locking recess for receiving the locking projection. After insertion of the connecting element in the recesses of the housing parts, the connecting element can be held by the coupling between the locking recess and locking projection in the drive housing. The locking recess is preferably formed continuously. The locking projection can be inserted in this case from two sides in the locking recess of the connecting element. The user therefore does not have to pay attention to the orientation of the connecting element.

The locking projection may have at least one bevel at its free end, which is aligned in the insertion direction of the connecting element. When inserting the connecting element this can slide over the slope. In the opposite direction then the connecting element is blocked and can not be removed. The recesses of the housing parts are preferably designed so that a non-destructive removal of the connecting element is not possible. The housing parts can be permanently connected in this manner after insertion of the drive rod.

The connecting element preferably has two Arretierausnehmungen which are formed symmetrically to a central axis of symmetry of the connecting element. The symmetry axis is perpendicular to the longitudinal axis of the connecting element. The user can thereby rotate the connecting element about this axis of symmetry before the introduction of the connecting element into the recesses of the housing parts. The user must thereby take no account of the orientation of the connecting element in the insertion direction.

In a preferred embodiment of the invention, the first, second and / or third recess and the connecting element have a rectangular cross-section. The production of the connecting element is characterized particularly simple and inexpensive, since, for example, sheet metal cutouts or other rectangular materials present can be used.

Both housing parts may have at least one, in particular round, through-opening, which are aligned in the connected state of the drive housing to each other, wherein the passage openings are formed perpendicular to the direction of movement of the drive rod in the drive rod guide. Through the passage openings, a cross-sectionally at least partially round fastening means, such as a screw, are performed. The two housing parts of the drive housing are thus additionally secured to each other. The passage openings can additionally be used to secure the drive housing in the pocket of the profile of the window or door leaf. Preferably, two passage openings are provided on a housing part, of which in each case one in a connected state, each with a passage opening of the other Housing part is aligned. The drive housing can be mounted in this manner rotatably in the pocket of the fold.

The driving rod guide may have at least one guide projection in which at least one recess is provided, which is aligned with the passage openings. Preferably, two recesses are provided on the driving rod guide, each aligned with an aligned pair of through holes. Through the recess or recesses, a tool can be introduced to mount a through-opening penetrating connecting element. Through the recess, for example, a screwdriver can be inserted to push a screw through round through holes and tighten the drive housing in the bag.

The drive device is preferably connectable to a handle assembly. The handle assembly can be connected perpendicular to the direction of movement of the drive rod in the drive rod guide and perpendicular to the direction of insertion of the connecting element with the drive device. The handle assembly can be screwed firmly to the drive housing, for example by means of screws. For receiving such a screw, the connecting element may have a through opening, which is in particular provided with a thread, wherein the through hole is accessible in the connected drive housing for a screw which is perpendicular to the direction of movement of the drive rod in the driving rod guide inserted into the through hole. The connecting element can thus simultaneously serve for connecting the two housing parts and for mounting a handle assembly.

Window and door leaves often have slight tolerances. As a result, the assembly of the drive device in the pocket of the fold can be made more difficult with simultaneous connection of the drive device to a handle assembly. The connecting element is therefore preferably in the insertion direction and / or in the direction of movement of the drive rod in the drive rod guide with play in the interconnected housing parts movable. If the handle assembly is fastened to the connecting element with a screw, tolerances can be compensated for by the play of the connecting element. The connecting element may have a certain play in the housing parts in all directions. However, the connecting element is advantageously dimensioned so that it has no play in the connected state of the housing parts in a direction perpendicular to the direction of insertion of the connecting element and the direction of movement of the drive rod. The two housing parts can be kept practically free of play together.

At least one centering lug can be provided on at least one housing part and at least one corresponding centering recess can be provided on the other housing part. Due to the arrangement of centering nose and Zentrierausnehmung the two housing parts can be precisely connected together.

In a particularly preferred embodiment of the invention, the two housing parts are identical. By forming identical housing parts, the production costs for the drive device can be reduced, Furthermore, the housing parts are easy to install. Furthermore, by the identical design of the housing parts a symmetry can be achieved in that the drive housing both can be mounted left or right on a window or door leaf. The drive device is thus versatile.

Preferably, two connecting elements for fixing the connection of the two housing parts are provided. The two housing parts can be so very firmly connected to each other.

The housing parts may be made of plastic and at least one connecting element made of steel or zinc die-cast. By the connecting element, a complete design of the driving device made of metal can be avoided. The drive device is so very easy and inexpensive to produce.

Further advantages will become apparent from the drawing, which represents two preferred embodiments of inventive drive devices.

a perspective view of a second drive device according to the invention.

FIG. 1a shows a first drive device 10. The drive device 10 has a drive housing 12 with two housing parts 12a, 12b. The housing parts 12a, 12b are identical. The housing parts 12a, 12b each have a drive rod guide 14a, 14b, which are formed in the form of guide projections. In the drive rod guides 14a, 14b, a drive rod 16 is guided. The drive rod 16 is covered by a cuff rail 18. To move the drive rod 16, this has a plurality of drive recesses, of which, for reasons of clarity, only a first drive recess 20a is provided with a reference numeral. In the drive recesses engages a drive pinion 22 a. To rotate the drive pinion 22, a four-edged mandrel recess 24 is provided which is connectable to a mandrel of an actuator, such as a handle of a handle assembly (not shown). By actuating the actuating element so the drive rod 16 can be moved. The drive rod 16 is in turn connected to locking elements, not shown, for locking a door or window sash.

The connection of the two housing parts 12a, 12b is made possible by two connecting elements 26a, 26b. To connect the two housing parts 12a, 12b, the housing parts 12a, 12b are plugged together in the direction of an arrow 28. Subsequently, the connecting elements 26a, 26b are inserted into first recesses 30a, 30b of the housing parts 12a, 12b. The direction of insertion of the connecting element 26a, 26b is indicated by an arrow 32. The connecting elements 26a, 26b pass through second recesses 34a, 34b when they are inserted into the housing parts 12a, 12b. By further movement in the insertion direction, the connecting elements 26a, 26b are finally inserted into third recesses 36a, 36b. The Connecting element 26a, 26b are in FIG. 1a shown in fully inserted condition. By the connecting elements 26a, 26b, the housing parts 12a, 12b are connected to each other in a structurally simple and cost-effective manner.

Centering tabs 38a, 38b, which are inserted into centering recesses 39a, 39b, additionally strengthen the connection of the housing parts 12a, 12b. Furthermore, the connection of the housing parts 12a, 12b is reinforced by the provision of securing projections and securing recesses. Due to the perspective view, only a first securing projection 40a and a first securing recess 41a are provided with a reference numeral. The second recess 34a is provided in the first securing projection 40a.

The drive housing 12 can be pushed against the direction of the arrow 32 in a pocket (not shown) of the door or window sash and fastened there by screws 42a, 42b. The screw 42a penetrates through the mounting of the drive housing 12 round through holes 44a, 44b of the housing parts 12a, 12b, which are aligned in the connected state of the housing parts 12a, 12b to each other. Furthermore, the screw 42b penetrates through the round passage openings 44c, 44d, which are also in the connected state of the housing parts 12a, 12b aligned with each other. Due to the penetration of the round passage openings 44a-d by the screws 42a, 42b, the housing parts 12a, 12b are additionally held together.

FIG. 1b shows the first housing part 12a and the first connecting element 26a according to FIG. 1a in a sectional view along the line BB. It can be seen here that a recess 46 is provided in the drive rod guide 14a. The Recess 46 is aligned with the round passage opening 44c. In the recess 46 may therefore be a tool, such as a screwdriver, for actuating the in FIG. 1b not shown screw 42b are introduced.

The first connecting element 26a has two locking recesses 48a, 48b. Furthermore, a locking projection 50 is formed on the housing part 12a. The locking projection 50 has a slope 52. As a result, the first connecting element 26a can slide over the bevel 52 during insertion. Subsequently, the locking projection 50 engages in the locking recess 48b. The second connection element 26b is latched in an analogous manner. As a result, the two housing parts 12a, 12b can be permanently connected by means of the connecting elements 26a, 26b. The locking recesses 48a, 48b are formed symmetrically to a central axis of symmetry 54 of the first connecting element 26a. The symmetry axis 54 stands perpendicular to the connecting element 26a. As indicated by an arrow 56, the first connecting element 26a can also be inserted rotated through 180 ° into the first housing part 12a. A user may therefore insert the first connecting element 26a in two orientations about the axis 54 in the housing part 12a.

Furthermore, the locking recesses 48a, 48b as
Passage recesses formed. A rotation of the first connecting element 26a about a second axis of symmetry 58 by 180 ° and subsequent insertion into the housing part 12a can be performed by the user, as indicated by an arrow 60, without changing the action of the first connecting element 26a. The first connecting element 26a is thus particularly easy to handle for the user.

The first connecting element 26a has a passage opening 62. The through-opening 62 is accessible through an opening 64 in the first securing projection 40a for a screw, not shown. The screw can be screwed into the passage opening 62 of the first connection element 26a. For this purpose, the passage opening 62, as in the present case, have an internal thread. Alternatively, a thread can be cut into a threadless through hole 62 by the screw.

The position of the second connection element 26b in the first housing part 12a is in a sectional view in FIG Figure 1c shown. In the insertion direction, ie in the direction of the arrow 32 and in the direction of movement of the drive rod, not shown, by an arrow 66, the first recess 30b and the third recess 36b are dimensioned larger than the second connecting element 26b. The second connecting element 26b is thus arranged in the insertion direction 32 and in the direction of movement 66 of the driving rod with play in the first housing part 12a. In the direction of movement 66 of the drive rod, the second connecting element 26b in the in Fig. 1c not shown second recess 34b (see Fig. 1a ) also a certain game on. When fixing a in Fig. 1c Not shown screw in a through hole 64 of the second connecting element 26b tolerances of the window or door leaf can be compensated. Furthermore, a stress-free mounting of the drive device 10 in a pocket of the door or window sash is made possible.

The first and second connecting elements 26a, 26b are identical. The properties of the first described above Connecting element 26a and the second connecting element 26b can thus be respectively completely transferred to the respective other connecting element 26a, 26b.

FIG. 2 shows a second drive device 10 '. The drive device 10 'is substantially identical to the drive device 10 according to FIG FIG. 1 educated. However, the housing parts 12a ', 12b' have larger driving rod guides 14a ', 14b'. As a result, two racks 68, 70 can be arranged between a drive pinion 22 'of the drive device 10' and a drive rod 16 '. The racks 68, 70 are identical. They have on their upper side drive recesses, of which, for reasons of clarity, only first drive recesses 72a, 74a are provided with a reference numeral. The racks 68, 70 have end coupling means in the form of recesses and projections, with which the racks 68, 70 with each other and on the drive rod 16 'can be arranged. By using the racks 68, 70, the distance of the drive pinion 22 'to the drive rod 16' can be increased. By using different numbers of racks so different mandrel sizes, ie different distances between the pivot point of the drive pinion 22 'and the drive pinion 22' facing away bottom 76 of the drive rod 16 'can be realized.
