Description

The invention relates to a device for arranging a housing of an actuating drive unit to a frame or the casement of a window. The invention also relates to an end cover for the device and a method for arranging the same.

In this description, reference is made to windows; a window within the scope of these explanations is however understood to also mean doors, skylights, roof hatches etc. The actuating drive unit is applicable for actuating windows, more preferably tiltable windows.

Actuating drives for actuation of windows are used to open and close windows in poorly accessible regions of buildings, for example. The actuating drive is arranged on a window casement, more precisely on a window frame, and actuates the window via a rope pull, chain pull or belt pull. The actuating drive and units necessary for driving and operation thereof, such as for example a power supply unit or driving electronics, are generally implemented in a housing. This housing has in most cases an elongated form, is arranged parallel to the pivoting axis of the casement and has the task of ensuring protection of the units implemented in it from undesirable external influences, such as dust, moisture or light.

The housing should ensure an attractive visual appearance of the actuating drive arranged on a window, see EP 777 028 A1 (Rasmussen), Figures 1 and 6 or DE 44 07 276 A1 (Geze), Figure 2. EP 534 413 A1 (Winkhaus) also shows a device for arranging a housing with an actuating drive, see Figure 2 and Figure 8 (reference numeral 54, column 9, from line 41) or Figures 10 to 12. DE 44 07 276 deals with a push-out device for a wing in a more detailed way, whereby Figures 1 and 2 present lateral angles holding a pivotable housing (2 therein), which is arranged on a fixed frame in a rotable manner. The consoles, referred to therein as angle holders 7, are described in more detail in Figure 9 thereof. They are arranged on the window frame and have mounting holes, 7b therein, for accommodating mounting screws, which are screwed in the window frame. They also have a bearing seat, 7a therein, for the pivoting axis of the housing described therein. The bearing seat is formed as a clearance hole, through which the axis of the housing is put, see column 3 thereof, lines 9 to 16 and column 5, lines 3 to 16. The drive is characterized more closely in that it is not only pivotable, but also its connection cable is conveniently led through the region of the pivoting axis, see column 10, claims 27, 28 and 29. Supporting the housing or “mounting” it in a rotatable manner is not provided except by way of the consoles 7 described above. The flexible push strap (5 therein), described therein in more detail, is rather mounted in different places of the longitudinal extension of the housing, as can be seen from the different embodiments of Figures 13 to 16.

During the process of assembling an actuating drive unit on a window, it is advantageous in view of their mostly poor accessibility to pre-assemble the actuating drive unit and the electrical units used for actuation thereof in the housing. The pre-assembled unit is arranged and assembled at the required place on the window. Subsequently, a connection with an electrical supply line necessary for operation of the actuating drive unit is established. Connecting the actuating drive unit to the electrical supply line often proves difficult, in particular in the case of poor accessibility of the window, for example at a considerable height or in a narrow wall opening. A further problem consists in the changing of the relative position of the actuating drive with respect to the assembly point of the flexible pull. In the case of tilting or pivoting windows, during opening or closing of the window, it should be ensured that this relative position corresponding to the particular opening angle of the window is duly followed up. If such a following up is not effected, the run-out or run-in direction of the flexible pull out of or into the housing is changed and jamming may occur. Smooth functioning of the actuating drive may then be more difficult to achieve.

In view of the previously described state of the art, it is the purpose of the present invention to provide a quick, simple and cost-effective way of assembling an actuating drive unit implemented in a housing on a casement or frame of a window, whereby a following up of the position of the actuating drive relative to the assembly point of the flexible pull corresponding to the opening angle of the window should remain possible.

The invention proposes a device (claim 1) for arranging the housing of an actuating drive unit for actuating the casement of a window. The arranging takes place on a frame or a casement of the window using a fastening element. The fastening element can be fixed in place on the frame or casement and can be pivotably connected to an end cover.

The fastening element can be a steel angle which is extrusion-coated using plastic (claim 3), which makes the fastening element, the end cover and the housing a perfect match in a visually appealing way and which also makes the fastening element - for reasons to be explained later in connection with the end cover - suitable for use in areas relevant in terms of fire protection.

The fastening element preferably has a (traversely directed) opening, which interacts with a part of the bearing pin of the unit as an end cover. According to a particularly advantageous embodiment, the fastening element has two such openings (claim 5). These openings are spaced at a different distance provided that the fastening element is fastened to the frame or the casement in accordance with its intended use, so that the housing can be mounted at various distances relative to the mounting surface. An adjustment to different window geometries or window fittings is possible. The at least one (bearing) opening is preferably designed as a thread hole, into which the respective bearing pin can be screwed with its threaded portion (claim 6).

In order to improve the adaptability of the housing accommodating the rotary actuator to the respective mounting conditions, the fastening element can have a slot for adjustable mounting on the window casement.

The device for arranging the housing on a casement (claim 1) can be additionally supported if elongated housings are used. The housing itself can be shorter or longer, while the elongated housing shape makes incorporation of more than one actuating drive possible. The two actuating drives arranged in the housing can either operate the same chain or two separate flexible pulls, which, as shown in Figure 1, are protruding from the housing at the outlet opening located in the direction of the frame. Nevertheless, the profile geometry of the housing does not have to be thicker or on average more voluminous, but can be extended in length in order to be able to also actuate broad casements.

The support is advantageously installed in the housing, so that by means of the further support element an element is created which engages in the housing and is able to serve as a pivot bearing in the housing (claim 8). For this pivot bearing, a pin is preferably provided as a counterpart (claim 9), which is preferably arranged in a slotted block (claim 13). This block can be inserted from an accessible side when the housing is open, then the housing is closed and, after mounting the fastening elements and placing the housings on the casement or frame, the further support element can be additionally mounted.

Preferably, the opening is located on the underside of the housing and is more preferably formed as a gap or a slot (claim 7). In addition, the further support element can have a narrow front (claim 10). Its narrowness allows intervention in the gap or slot oriented traversely to the longitudinal extension. Behind this gap or slot the pin is fixed or positioned and is gripped in mounted manner by the receptacle (claim 8).

Its length makes it seem reasonable to provide the additional support essentially in the middle between the two “end bearings” (claim 11), which are defined by the fastening elements and their being engaged in the end cover. A particular advantage of the additional support is that it can be placed into the housing in an almost concealed way and at the same time enables pivoting (claim 12), whereas this pivoting option is implemented subsequently, when the main assembly of the housing on the casement has already been completed. This is an advantageous embodiment, not an absolute necessity.

The invention also proposes a method (claim 19) for arranging a housing of an actuating drive unit for actuating windows and the like, preferably of tilt-and-turn windows or skylights, on a frame or a casement of the window. Thus, the afore-mentioned problem is also solved, in particular, establishing the electrical connection is achieved in a quick, safe and easy way, even in an unfavorable environment.

An end cap and a cover cap form the end cover, whereas the end cap is designed for terminal attachment on the housing (claim 2, claim 14) and the cover cap is connectable to or detachable from the end cap, depending on the opening and closing. The end cap is designed in a way that it can be pushed onto the housing in a first direction and the cover cap is connectable to the end cap in a direction essentially perpendicular to the first direction.

To some extent, the end cap engages in the housing. Thus, it is inserted. When removing the end cap, it is done inversely. The end cap is pulled off in a direction opposite the first direction. The cover cap is detached in a direction opposite the second direction. The first direction is essentially the longitudinal direction.

The housing is elongated and narrow, so that it can be arranged on a frame or casement or the like without concealing the window pane.

The actuating drive and further units for its control can be arranged to be preferably fixed in place in the housing by means of a pre-assembly. The housing preferably consists of a profile element, for example an extruded profile, both front ends of which are open.

The end cover closes one of these open ends. It can only be provided on one end of the housing if the housing has only one open end. If a housing has two open ends, an end cover is advantageously provided on each end.

The end cover preferably forms a bearing structure, enabling the housing to be pivoted about an axis parallel to the pivoting axis of the window in order to facilitate the previously described following up. The end cap forms to gether with the cover cap (as a lid) the end cover which closes the housing at its end or its ends in the required manner. The end cover is open on two sides, in the longitudinal direction and vertically thereto, preferably below. The lid closes the second opening and ensures a simplified electrical connection, which can be assembled quickly.

In an advantageous manner, the end cap is designed to be also arranged during pre-assembly of the actuating drive unit in the housing on the same. The end cap can be (pre-)assembled on the housing with the cover cap arranged on the end cap or alternatively without the cover cap.

The end cap closes the housing in the required manner on the end side, whereas accessibility to the housing’s interior is guaranteed by the opening of the end cap which can be closed by means of the cover cap. Since the end cap can be pushed onto or into the housing in a first direction and the cover cap is connected to the end cap or detached therefrom in a direction essentially perpendicular to the first direction, the pre-assembled and almost completely closed unit comprising the housing and the end cap and units incorporated in the housing can be assembled on the corresponding window, in particular in the case of poor accessibility of the intended assembly site. Even if the space laterally next to the cover cap is severely restricted, accessibility to the housing’s interior is always guaranteed via the opening - which is only closed by the cover cap.

According to a particularly advantageous embodiment of the invention (claim 18), it is proposed that the cover cap has terminals designed as a plug. In this case, the electrical supply line may likewise be connected to the terminals designed to form the plug of the or “on the” cover cap during pre-assembly. A corresponding counter-piece to the plug, which is connected electrically to the actuating drive, for example during pre-assembly of the actuating drive in the housing, is arranged at a corresponding position within the housing or within the end cap. In order to supply the actuating drive with electrical energy, the cover cap is simply inserted into the end cap along the second direction, whereupon the electrical connection between the supply lead and the actuating drive is closed via the plug and the correspondingly designed counter-piece is closed as a contact group (claim 16).

In order to keep the cover cap securely in the end cap, it is provided according to a further embodiment that the cover cap interlocks automatically with the end cap by means of catch structures for an arrangement on the end cap (claim 16).

According to a further embodiment of the invention, the end cap has a metallic core, for example an angle made from steel. This core may form the overall essential structure of the end cap. In combination with a likewise metallic housing, such an end cover can also be used in regions relevant for fire prevention, for example for opening and closing a window serving as a smoke outlet. Alternatively, the core may be present only in some parts of the end cap, for example as a reinforcement, in which case the structure of the end cap covering the end-side opening of the housing may be formed from different materials. In order to achieve an appealing appearance, it is proposed according to a further embodiment of the invention that the metallic core of the end cap is encased in plastic, at least in the axial end region (claim 18). An uncoated part protrudes for the purpose of connection with the housing (claims 18 and 15).

In a further embodiment, the end cap has one or more bearing openings for a bearing pin to form a pivot bearing together with a fastening element, which can be assembled to be fixed in place on a frame or a casement of the window, and a bearing pin. The fastening element has a counter-piece corresponding to the bearing pin or the bearing opening of the end cap, so that the housing can be arranged pivotably on the frame via the mounting formed by the fastening element and the end cap. When opening the window casement, the rotary position of the housing which depends on the opening angle of the window and hence of the actuating drive relative to the fixed frame of the window is adjusted preferably automatically via the pivoting mounting, as a result of which an ever faultless function of the actuating drive is achieved. Tilting or jamming of the pull which is moved out or moved into the housing is prevented.

The end cap preferably has at least one bearing opening for receiving a bearing pin. The latter extends into the interior of the end cap, that is, through the axial end region of the metallic core and the plastic surrounding it. The diameter of the opening provided in the core itself is preferably greater than the diameter necessary for receiving the bearing pin.

This way, the inner edge (between the core and the bearing pin) of the bearing opening of the core is also encased in plastic, so that the bearing pin is mounted in the plastic of the end cap and is thus spaced apart from the metal of the core. In this manner, an easily rotating mounting is achieved.

The end cap (claims 2, 14, 15, 17) is therefore particularly suitable for an RWA application (“Rauch-Warme-Abzug” [fume and heat venting fitting]). If for example the plastic of the end cap surrounding the core melts due to heat exposure, insertion of the bearing pin into the opening of the core and the pivoting mounting’s ability to function are also guaranteed. In spite of the melting of the plastic encasement, the material of the core gives further support to the bearing pin inserted into the respective bearing opening.

Further advantages and embodiments of the present invention can be seen from the following description of preferred but not restricting embodiments based on the figures.

Figure 2 shows the end cover 1 of Figure 1 in a perspective view with a removed or not yet mounted lid 3 as “cover cap”

Figure 3 shows the end cover of Figures 1 and 2 in a further per spective view from a different direction of view, wherein a housing 10 is shown in a dotted line, laterally covered and with the end cap 2, on which the lid 3 is not yet mounted.

Figure 4 shows a device suitable for pivot bearing in a sectional view IV-IV of Figure 5.

Figure 5 shows the device of Figure 4 in a lateral view.

Figure 6 shows an enlarged cutout from Figure 7 in vertical cutting, with a clarification of a further supporting element 40, which additionally supports and mounts the elongated housing 10 between its two end-side fastening elements.

Figure 7 is a reduced representation of the frame with an elongated housing attached thereto, in which the further supporting element (40) designed as an angle is prepared for engagement.

Figure 7a is an enlarged cutout of the engagement slot 10’, in which the further supporting element 40 engages with its front end to thus achieve a supporting and bearing function on the inner side of the housing, and which can be seen in more detail from Figure 6.

Fig. 1 shows an embodiment of the invention in a lateral view. The end cover 1 has an end cap 2 and a cover cap 3 as the lid.

As can be seen in particular in Figures 3 and 4, the end cap 2 is arranged on the end side of a housing 10. The housing 10 consists for example of a hollow extruded profile, the open ends of which (in the figures only one of them is shown) are closed by end covers 1. The housing has a central opening 9, on which a lead 8a, which can be seen in Figures 1 and 5, for a chain pull, rope pull or belt pull not shown in the figures, is arranged. This pull is attached by an end piece 8 to a frame R of a window casement shown only schematically. Its other end is connected to an actuating drive which cannot be seen in the figures and which is implemented in the housing 10, which in turn is arranged on the window casement by means of an end cover 1 at any front-end side and the fastening elements 20 described in more detail in the following.

The end cap 2 is designed for example as a plastic injection-molded part, whereas the plastic 11 encases a steel angle 4 which protrudes partly from the plastic material of the end cap 2 and is provided in the protruding leg 4b with two openings 26a, 26b. On the front-end side, the end cap 2 is provided with two bearing openings 6, 7 arranged next to one another and which are designed as blind holes and are provided with a closing injected skin 6a or 7a.

The steel angle 4 serves to stabilize the end cap 2 and attach it by means of two blind rivets 5, 5a to the housing 10. The second leg 4a of the steel angle 4 connected to the leg 4b supporting the blind rivets is - as can be seen in Figure 4 - provided with at least one passage opening 30, through which the bearing pin 19 is passed. The dimension of the passage opening 30 is greater than the diameter of the bearing pin 19. The gap between the outer surface of the bearing pin 19 and the inner edge of the passage opening 30 is filled with the plastic of the end cap 2.

The plastic material used therein forms the bearing opening 7 with a bearing surface for the bearing pin 19, so that a slight pivotability of the bearing pin 19 in the bearing opening 7 is produced.

The same applies to the opposite bearing opening 7 of the other cover 1. In each case, the opening 6, to which the same also applies, is located next to it. It has a passage opening 30’ in the leg 4b and may alternatively receive the bearing pin 19. The material of the steel angle 4 surrounding the bearing opening 6, 7 reinforces the bearing and serves furthermore to continue to guarantee the bearing function during breakdown of the plastic material - for example by melting in the event of a fire.

The shape of the leg 4a of the steel angle 4 can be seen from Figure 1, in which the latter is shown in a dotted line. The leg 4a is widened and carries both openings 30, 30’.

Furthermore, the end cap 2 has on the lower end in Figure 2 on the front-end side a cable recess 28. On the lower side of Figure 2, a cover cap recess 27 is furthermore provided. On the edge side of this cover cap recess 27, the end cap 2 is provided in its inner region with locking projections 16a, 16b for releasable attachment of the cover cap 3. Furthermore, it has a groove 18 and a catch spring 17 creating a fixed arrangement of a socket not shown in the figures with electrical contacts as a contact group which is connected in electrically conductive manner to corresponding peripheral units of the actuating drive. This can preferably be achieved by using a circuit board not shown in the figures and which is held detachable by the catch spring 17, and can on the other hand, after inserting the edge of the circuit board into the groove 18, be locked into the catch spring with the other edge of the plate.

As shown in Figure 4 or 1, the lid is inserted as a cover cap 3 into the lid or cover cap recess 27 of the end cap 2 intended for it.

The lid 3 has in Figure 3 visible springy catch projections 13a, 13b, laterally arranged, which engage into the first catch projections 16a, 16b of the end cap 2 when the lid 3 is arranged in the cover cap recess 27.

The cover cap 3 also has a cover piece 12 which in this case closes an opening 28’, wherein the opposite cover piece 12a closes the cable recess 28a of the other end cap 2.

The cover piece 12, 12a is provided with a theoretical breaking point which is not shown in the figures, so that it can be removed from the cover cap 3 for the purposes of cable insertion through the cable recess 28 or 28a. In case the cable insertion does not take place on the relevant end cover, the non-opened cover piece remains on the cover cap (lid) and closes the cable recess which is not required.

The cover cap 3 as the lid supports a plug 14 provided with a connection strip 15, the plug 14 being in a recess 14a which is adapted to the plug housing. For the purposes of supplying the actuating drive with electrical energy, the plug 14 is connected to an electrical supply line during preassembly - which means that the cover cap 3 as a lid is not yet arranged in the cover cap recess 27 in the intended manner. The plug 14 is supported by the cover cap 3 in such a way that it engages into the contact group arranged in the end cap 2 with plug sockets for the intended arrangement thereof in the cover cap recess 27 and hence electrical connection between the supply line and the actuating drive is established. The contact plug is connected conductively to the contact socket. This connection may be released again when the lid is being detachably removed from the cap 2. The catch connections (corresponding catch projections 13a, 16a and 13b, 16b) thus release the lid in a re-lockable manner.

Furthermore, an attachment element 20 is provided. It is designed to be essentially angular and has a bearing leg 24 and a supporting leg 25. The bearing leg 24 is arranged on a window casement, in particular a frame, for the purposes of an arrangement of the unit comprising the actuating drive, the housing 1 0 and the end cover 1. The present description refers to the case of an arrangement on a window casement R.

The bearing leg 24 is provided with a passage opening 29 and an elongated hole 22. With the help of the elongated hole 22, the fastening element 20 is first of all screwed on the window casement. A subsequent precise positioning of the fastening element 20 is possible via the displaceability achieved by the elongated hole 22 in the direction of its longitudinal axis. The fastening element 20 is fixed in the corresponding precise position by means of a screw engaging through the passage opening.

The supporting leg 25 has a head region, in which two pin openings 23a, 23b are 23a, 23b are arranged next to one another. One of these two serves to receive the bearing pin 19.

The relative position of this unit with respect to the window casement can be adjusted by an optional mounting of the unit comprising the end cover 1 and housing 10 in the pin opening 23a or the pin opening 23b - via the pin 19.

The pin openings 23a, 23b are designed as threaded holes, into which the bearing pin 19 with a thread 21 may be screwed and hence is axially without play. Figure 5 illustrates the engagement of the bearing bolt 19 in the screw opening 23a.

The assembly of the end cover 1 or of the device on the housing 10 is described below.

During pre-assembly, the actuating drive unit and optionally peripheral units necessary for driving thereof, are arranged in the housing 10 and accordingly connected electrically to one another. The contact group to be arranged later in the end cap 2 is electronically connected to the actuating drive or the peripheral units. Then the end cap 2 is arranged on the end side of the housing 10 and attached thereto by means of blind rivets 5, 5a. The cover cap 3 is thus removed from the cover cap recess 27. During or after the arrangement of the end cap on the end side of the housing 10, the contact group is arranged as intended in the groove 18 and held by the catch spring 17, preferably on a stretch of the circuit board. The circuit board thus lies on a strip base 18a and is held by the locking nose of the catch spring 1 7.

The cover cap 3 is arranged in the cover cap recess 27 of that end cap 2, on the side of which no feed of the electrical supply line is effected, by simply inserting (in Figure 4 from below) the cover cap 3 into the cover cap recess 27, until the springy locking projections 13a, b latch into the catch projections 1 6a, b.

In order to effect the supply of the electrical supply line, the cover piece 12a is removed from the cover cap arranged on the other side. The electrical supply line, which is already present in the window area, is passed through the resulting opening of the cover cap 3 and connected in an electrically conductive manner to the connection strip 15 of the plug 14. The plug 14 is then arranged as intended in the cover cap 3. The cover cap 3 is subsequently inserted together with the plug 14 into the cover cap recess 27 of the end cap 2 until also its springy catch projections 13 a, 13b lock with the corresponding catch projections 16a, 16b of the end cap 2. Due to this insertion, the plug group 14 engages automatically into the contact group arranged in the end cap 2.

The fastening elements 20 are firmly screwed at corresponding positions of the window casement. In order to arrange the unit comprising the actuating drive, the housing 10 and end cover 1 on both sides on the fastening elements 20, for example the pin openings 23a of the fastening elements 20, 20’ and the associated bearing openings 7 of the end caps 2 are brought into covering alignment with one another and a particular bearing pin 19 is screwed in (on each axial front-end side).

The overview of the arrangement of an elongated housing 10 on the casement can be seen from Figure 7. The housing 10 is arranged on the casement R with two “end bearings”, wherein the end bearings are designed in a way as shown in Figure 5 in the lateral view. Each end bearing has a fastening element, wherein the fastening elements 20, 20’ are preferably provided as angular fastening elements which can be connected to the front-end side of the end cover of the housing 10 using one bearing pin each.

It is shown in Figure 7, the enlarged cut-out of which is Figure 7a (from the center where the further supporting element 40 is provided), and in the sectional view in the plane of the further supporting element 40 according to Figure 6, in each case an assembled state. It goes without saying that the device for assembly of the housing 10 at first consists primarily of the two fastening elements on the two end-face ends and the further supporting element 10, for example in the center between these two.

The further supporting element 40 in this example is of angular nature, wherein it has a first contoured leg 40a and a second assembly leg 40b running vertically thereto. Closer to the attachment surface on the frame, the contoured leg 40a has a contour recess 40c which provides this leg with an arm 40d appearing to be narrow, as can be seen in the sectional view of Figure 6. On the front end, this engagement arm 40d changes its direction essentially vertically upwards as a front end section 40e, into which a recess 41 is introduced, which serves the pivotable receiving of a supporting bolt 51, as can be seen in the sectional view.

The bolt 51 cannot be seen in Figures 7, since it is arranged within the housing 10. The arrangement of the bolt is such that a block 60 is provided which is slotted vertically and the bolt 51 is placed in this slot. The block 60 is - while the housing 10 is open - inserted from the front and sits precisely fitting in corresponding recesses within the housing.

It can be seen from the direction of insertion E of Figure 7a and the assembled state of Figure 6 that a support and at the same time rotary mounting is achieved with the further supporting element. The further supporting element engages deeply into the housing, which provides a corresponding opening. This opening 10’ is designed as a gap or slot in one wall of the housing 10, as can be seen from Figure 7a.

The recess 41, which serves as a receptacle for the bolt 51, is provided in the front end section 40e. An - inlying - pivoting bearing is thus formed in the housing 10. The pivoting bearing arranged in the housing also serves as a support. The support protects against bending forces that are too great within the elongated housing, for example by incorporating several actuating drives or due to a particularly great length. Bending may thus be largely avoided, nevertheless the housing may still follow the pivoting and lowering movement of the casement during moving-out of the - one or more - chain(s) and occupy a correspondingly modified rotary position.

Twin drives with two actuating drives in the elongated housing are preferred here, wherein at least one flexible pull, preferably two separate flexible pulls, are moved out of two spaced openings 9 to trigger the control of the casement movement starting from two fixed sites on the fixed frame.

During assembly, the further supporting arm 40 may be inserted subsequently when the housing itself is already assembled, which is the purpose of the two fastening elements 20, 20’ on the end sides. The angular supporting element provided with the front narrow arm 40d is thus coupled from below through the opening 10’ engaging around the bolt 51 for the mounting. Then the second leg 40b is screwed to the casement at corresponding screw openings.

The result in case of an elongated, straight housing is an essentially central slot or gap, into which the support may subsequently be inserted in order to then be assembled. A rotating movement within the scope of a pivoting movement of the housing is also possible. The length of the gap or of the slot 10’ is designed accordingly in pivoting movement thereto. On the other hand, a relatively narrow definition of the gap between the engaging arm section 40e and the residual wall of the underside of the housing 10 may be provided in longitudinal direction of the housing.

The pivoting bearing 41/51 is brought close to the vertical plane of the assembly surface M due to the shape and inclined alignment of the arm 40d of the further supporting element and considerable torques may be avoided.

The inner edge 10k of the slot 10’ has movement space when following the angular position of the housing 10 due to the shape and inclined alignment of the arm 40d before it reaches the edges 40k of the arm 40d, thereby limiting pivoting.
