Abstract

The gear comprises hollow profiles, with a housing (22), in which a pinion (23) provided with a multi-edged recess (28) is rotatably located for the operation of a drive rod. Next to the pinion is at least one tapped hole (29) for a fixture screw. The tapped hole is formed in a displacement part (30'), which is displaceable in the housing axially and in its engagement position does not extend over the one side surface (35) of the housing and in its disengaged position extends over this side surface to engage in a hole in the hollow profile of the pane frame.

Description

The invention relates to a transmission for insertion in a recess of an existing of hollow profiles Casement of a window, a door or the like according to the preamble of the claim 1.

Such a transmission, as it is from the DE-GM 8 714 187 is known from the fold side of the casement attached to the casement. Around a low height in the chamber area between the Folded surfaces of the casement and the frame to achieve is within the undercut Guide channel for the longitudinally displaceable reception of the Driving rod the channel base with a recess provided, whose cross-section essentially on the Cross section of the housing is adapted. So that arrives an essential part of the housing into one arranged behind the guide channel Casement hollow profile. To the immersion depth of the Limit gearbox is on everyone Narrow end of the housing in the longitudinal direction of the housing extending web, with its Edition on the channel bottom the depth arrangement of the Gearbox is determined. To achieve an easy Introduction of the housing in the recess in The cross section of the channel is used to compensate for Manufacturing tolerances and to simplify processing kept slightly larger than the housing cross-section. To ensure an exact fixation of the gearbox to reach in the longitudinal direction of the guide channel each bridge of the housing carries a semicircular Platelets, each with a positive fit engages in an assigned hole in the channel base.

The gearbox is operated using an operating handle, whose rosette on the visible surface of the Sash is to be put on. A square mandrel of the The control handle fits into the polygonal recess of the pinion, and the mounting screws for the rosette are in the threaded holes of the housing. The rosette usually has the fastening screws surrounding Centering approaches to also for the rosette of the Control handle an exact arrangement on the casement to obtain.

The faceplate arranged outside the guide channel the gear is provided with a cam, which is at the back of the viewing area and the overturning wall of the hollow profile supports. This is to prevent the gearbox from tilting be avoided due to the screw fastening with the rosette.

The rosette holes arranged in the visible surface to accommodate the centering lugs and / or the Fixing screws of the rosette and the hole are usually used for the passage of the square mandrel with a triple drill head made with uniform Diameters and distances. The axes of the in bores arranged on a common plane as far as possible within the wall thickness of the wall of the hollow profile forming the channel base, by tightening the fastening screws emerging, acting on the gearbox, Avoid harmful torque if possible.

The gearbox is attached to the casement expensive because two independent from each other Operations must be carried out, namely the Production of the holes in the channel base for positive locking the approaches of the webs and the manufacturing the rosette holes and the hole for the Square mandrel of the operating handle in the visible area of the casement. Although the aforementioned hole in two different levels with different Tools at different times must be manufactured, the holes of each In turn, levels are precisely coordinated to avoid jamming. These holes are therefore to be manufactured with the greatest care.

When handling the wing with built-in Gearbox, but with control handle not yet mounted, there is a risk that this is only loose used gear unintentionally from its installation position solves. This can also occur when transporting the finished windows are made for the sake of better Use of the mailroom, especially without screwing on Control handle will be shipped.

The object of the invention is a generic To further design gearboxes that while facilitating assembly on the casement without additional processing effort on the casement an exact centering of the gearbox to the rosette the operating handle is done, achieving sufficient hold of the gearbox on the casement even without an attached operating handle.

Based on the preamble of claim 1, this object is achieved according to the invention by that the threaded bore is formed in a sliding part is arranged axially displaceably in the housing is and one in its engagement Side surface of the housing is not or not significantly towered over and in its release position this side surface for engaging in a hole or the like of the hollow profile protrudes. In engagement the sliding part can be the gear slide into the recess of the casement. If the slide-in end position is reached, it takes effect the sliding part in the disengaged position in the hole or the like of the casement and keeps the gearbox in its assembled position Position.

The sliding part is preferably designed as a sleeve. In particular, two are on both sides of the Ritzels lying sleeves provided. The hole in Casement in which the sliding part in disengaged position engages, is preferably as a rosette hole formed by a threaded screw for fastening a rosette on the Visible area of the casement when assembled is penetrated.

The housing of the threaded holes in the housing of the gearbox to hold the fastening screws for the rosette of the control handle in one Sleeve, which in turn is axially displaceable in the housing is stored, allows different positions the sleeve to the housing.

For inserting the housing into the recess in the base of the duct the sleeve will be in the reset position held in which the free end face of the Sleeve essentially flush with or even slightly recessed opposite the assigned side surface of the housing is. The gear can thus be unimpeded can be inserted through the sleeve.

If the gearbox is in contact with the housing in the longitudinal direction and in the longitudinal direction of the guide channel extending webs of the housing the bottom of the sewer reaches its correct installation depth the sleeve is in its other end position in which they pass over the side surface of the Housing is arranged above. With this change the sleeve reaches the area of the rosette hole and is guided by this. The rosette holes in conjunction with the foregoing On the one hand, sleeves fix the Gear in the longitudinal direction of the guide channel and on the other hand the correct assignment of the threaded holes and thus the housing of the gearbox to the rosette of the control handle. The diameter of the Centering approaches of the rosette and the diameter of the part of the Sleeve are the same size. The rosette holes are thus not only for fixing the rosette of the Control handle used, but also also for fixing the housing of the gearbox.

After installing the gearbox in the recess of the The sleeves are located above the side surface at the bottom of the channel of the housing and engage in parts of the rosette holes on. The gearbox also cannot more in the plane perpendicular to the fold surface from the The recess will fall out by reaching under the Cross bar of the guide channel by means of the sleeves. The gearbox is therefore already against an unwanted one Secured digging without it being the previously necessary attachment of the control handle on the visible surface of the casement. Of the Transport of the wing provided with the gear or window can therefore also without screwed on operating handle. Already with the rosette holes alone is a fixation the gearbox achieved and it does not need more of the additional processing previously required using holes perpendicular to the fold surface. Also the measure of the length of the recess in the longitudinal direction of the guide channel no longer needs to be careful be observed as the longitudinal fixation within the rosette holes are made.

Is preferably between the sleeve and the Interposed a spring, and the The sleeve is in the pushed-back end position against the housing can be fixed. So the sleeve is always held under tension in the housing, the Preload in the pushed back end position of the Sleeve in turn from the housing by fixing the Sleeve is added to the housing. After the release of the fixation causes the spring independent transition of the sleeve into the extended, protruding over the side surface of the housing End position of the sleeve.

So that the sleeve is fixed in the retracted position End position can be easily lifted the sleeve on the free end face with an actuation intervention provided, in particular as Longitudinal slot for the blade of a screwdriver is designed.

The bearing point is particularly advantageous to hold the sleeve in one shell as a through hole and in the other shell as The through hole is a blind hole with a distance from the side surface of the Housing-ending longitudinal groove and the blind hole with a circular section in the area the longitudinal groove, and there are longitudinal groove and expansion against the parting surface of the shells open and the sleeve with a circular cylindrical Cross section has a nose on the outside diameter on that in the extension or Langsnut the bearing is protruding. The bowls the housing are usually made from a single casting formed, in particular from a zinc die-cast part. The holes for receiving the sleeve including extension and longitudinal groove can be without additional Mold in effort, especially as expansion and longitudinal groove each starting from the parting surface of the shells are, and the sleeve can be assembled of the gearbox comfortably. The sleeve is then stored captively in the housing, on the one hand by the design of the bearing in one Shell as a blind hole and on the other hand in the another shell in that the longitudinal groove of the through hole not to the side of the case is continuously formed.

The sleeve is in the retracted position their nose within the extension of the with of the blind hole provided and at the same time out of range in the extension opening longitudinal groove of the other shell. The Spring presses against the front surface of the nose the interface of the other shell, which is the axial movement the sleeve prevents. To the sleeve in bringing the other end position is minor to twist, for example by 30 ° or 45 °, until the nose reaches the area where the longitudinal groove of the other shell is arranged and culminates in the expansion. So that's the Sleeve restraining parting surface of one shell interrupted, and the spring then presses automatically the sleeve in the extended end position, whereby the nose of the sleeve slides along the longitudinal groove. The maximum end position is reached when the nose on End of the longitudinal groove. This is the sleeve stored captively in the housing.

To avoid the depth of the housing of the gearbox enlarge, the spring rests on the ground at one end the blind hole is at the other end in one Threading the sleeve out, and the inner Diameter of the spring designed as a compression spring corresponds at least to the diameter of the threaded hole the sleeve.

It is particularly favorable that the diameter of the Bores of the bearings and the adapted Diameter of the sleeve is larger than the diameter the rosette holes and that the sleeve in the area the free face with a circular cylindrical Approach is equipped, the diameter corresponds to the diameter of the rosette holes. This creates a covenant at the transition to the approach, the one in the extended end position over the side surface the housing is protruding. In built The state of the gearbox lies on the to the longitudinal end edge adjacent to the rosette holes the recess in the base of the canal and on one Face of a crossbar of the guide channel, if the width of the recess in the channel bottom of the opening width of the guide channel between its Cross bars corresponds. When screwing the rosette with the gear the federal government is against said Surfaces of the hollow profile pressed and tilting the gear in the hollow profile is avoided. The resilient, axially movable bearing of the sleeves is based on different tolerances independently, without negative effects on the Transmission.

To a compact design in the height of the gear the sleeve can be reached with one of the faceplates adjacent flattening, which itself over the protruding over the side surface of the housing Range of the larger diameter of the sleeve extends. The bores of the bearing points can this extends into the area of the faceplate extend into it without the axial displacement the sleeves affected by the faceplate is.

To facilitate the insertion of the gear in the recess of the channel bottom is the housing in Direction of insertion conical.

Further advantageous embodiments are in the subclaims featured.

The window of Figure 3 consists of the frame 1 and the sash 2, each of which is extruded Hollow sections of an aluminum alloy exist. From the for operating the casement 2 and for unlocking or locking serving fitting is a gear 3 in Figure 1 shown, which is coupled with two drive rods 4 is. The drive rods 4 are mounted to be longitudinally displaceable in a arranged on the fold surface 5, extending along the wing spars of the wing frame 2 Guide channel 6, the channel base 7, the side bars 8 and the cross bars 9 are formed is. To insert the gear 3 is in the channel bottom 7 milled a recess 10, the width the opening width limited by the crosspieces 9 of the guide channel 6 corresponds. To be operated the transmission 3 by means of an operating handle 11, the one on the visible surface 12 of the casement 2 rosette 13 to be placed and one in it rotatably mounted handle 14. The handle 14 is with a square mandrel 15 for coupling with the Gear 3 provided, and on both sides of this Square mandrel 15 carries the rosette 13 each Centering approach 16 which is hollow for Carrying out the fastening screws for fastening of the operating handle 11 on the visible surface 12 of the casement 2. To put on the rosette 13 is the visible surface 12 with three holes 17, 18th provided with the same diameter, the middle Mandrel bore 17 for the passage of the square mandrel 15 serves and the other two rosette holes 18th to accommodate the centering lugs 16. The axes these bores 17, 18 run within the channel base wall 19, as shown in particular in FIG. 3, the bores 17, 18 on the longitudinal end edge 20 of the recess 10 end.

The gear 3 consists of the faceplate 21 and the housing 22. The faceplate 21 can be stationary be formed with the housing 22 and then carries a transmission link on which one in the housing 22 acts rotatably mounted pinion 23, which the transmission link shifts and this movement transmits on connecting rods, as from the DE-GM 8 714 187 is known, or the faceplate 21 guided longitudinally on the housing 22, actuated by means of the pinion 23, such as DE-GM 8 814 754 teaches.

The housing 22 is also from the narrow end faces 24 outgoing, in the longitudinal direction of the housing 22nd extending webs 25 provided on the channel bottom 7 lie in Figure 1.

The faceplate 21 of the gear 3 of Figure 4 is guided longitudinally on the housing 22, the Drive via the pinion 23 mounted in the housing 22 takes place directly in the teeth of the faceplate 21 engages. The pinion 23 has a polygonal recess a square recess 28 for coupling with the square mandrel 15 of the operating handle 11. To Both sides of the pinion 23 are on the housing 22 threaded holes 29 for receiving the fastening screws for the rosette 13 of the control handle 11.

The threaded holes 29 are each within of a sliding part 30 ', the sleeve 30 is formed, which is axially displaceable in the housing 22 is stored. As a storage location for admission the sleeves 30 carries the front shell 26 a Through hole 31 and the rear shell 27 a Blind hole 32. The through hole 31 has a longitudinal groove 34 extending from the separating surface 33 on that just before the side face 35 of the front shell 26 of the housing 22 ends. This is particularly so 7 and 8 can be seen. The blind hole 32 of the rear shell 27 has a circular section Extension 36 on, also from the parting surface 33 starting. For housing 22 composite shells 26, 27 opens the longitudinal groove 34 against an end region of the extension 36.

The design of the sleeve 30 and its assignment to the housing 22 is in particular the cuts of the Figures 7 and 8 can be seen.

In Figure 7, the transmission 3 is shown after Process of inserting the gear 3 on the casement 2, with the insertion depth being limited by the support of the webs 25 of the housing 22 the channel base 7 and the housing 22 the recess 10 penetrated in the channel base wall 19. Here is the faceplate 21 above the Crosspieces 9 at a short distance from it and longitudinally displaceable mounted on the housing 22.

The blind hole 32 of the rear shell 27 and the Show through hole 31 of the front shell 26 same diameter and store the sleeve 30, whose outside diameter matches the inside diameter of the Bores 31, 32 is adapted. At this outside diameter the sleeve 30 carries a nose 37. The Nose 37 strikes in the end position of FIG. 8 the end of the longitudinal groove 34 to limit the Axialverschewegs the sleeve 30 to the outside, about the side surface 35 of the front shell 26 protrudes. This is followed in the area of the free end face the sleeve 30 a circular cylindrical projection 38, its diameter to the diameter of the rosette hole 18 is adapted. Between approach 38 and the thick part of the sleeve 30 thus becomes a collar 39 educated. The approach 38 is with a slot trained actuation intervention 40 equipped. The sleeve 30 also has one against the bottom 42 the blind hole 32 open recess 41. In this recess 41 a spring 43 is arranged, which is supported on the bottom 42 of the blind hole 32.

In Figure 7, the sleeve 30 is in against Force of the compression spring 43 pushed back end position. The nose 37 is located within the Extension 36 of the rear shell 27, offset opposite the longitudinal groove 34, so that by the spring 43 the front surface 45 of the nose 37 against the parting surface 33 the front shell 26 is pressed. Hereby a fixing device 51 is formed. Here does not protrude the free end face of the sleeve 30 or just a little over the side surface 35 of the Housing 22 before. Introducing the housing 22 in the recess 10 in the channel base 7 of the casement 2 is thus not affected by the sleeves 30.

A tool is guided through the rosette bore 18 and attached to the actuating engagement 40. Means of the tool, the sleeve 30 becomes approximately 30 ° twisted up to 45 °. The front surface 46 slides the nose 37 under tension on the interface 33 along the front shell 26. As soon as the nose 37 Is covered with the cross section of the longitudinal groove 34, the sleeve 30 is guided through the nose 37 and longitudinal groove 34, towards the side surface 35 of the housing 22 moves and at most so long until the front surface 45 of the nose 37 on the End of the longitudinal groove 34 comes to rest, as in Figure 8 shown. So that this axial movement of the Sleeve 30 not by striking the faceplate 21 is limited, the sleeve 30 with a Flatten 44 provided so that the thicker Part of the sleeve 30 and thus the collar 39 over the side surface 35 of the housing 22 protrude can. During this axial movement of the sleeve 30 arrives whose approach 38 each in the associated rosette hole 18 and is thus carried on its scope. The axial movement is ended when the Collar 39 on the longitudinal end edge 20 of the recess 10 comes to the plant.

Now the control handle 11 is on the visible surface 12 of the sash 2 placed, the Centering lugs 16 in the rosette holes 18 in Area of the rollover wall 46 with a positive fit are used. By the centering lugs 16 Rosette 13 are then inserted fastening screws and with the threaded bores 29 of the sleeves 30 screwed. This results in tension between the rosette 13 and the sleeves 30. Tolerance deviations in the hollow profile or on the gear 3 are thereby by the axially resilient bearing Sleeve 30 added as long as the nose 37 in the protruding end position not at the end of the Longitudinal groove stops.

To remove the gear 3 are after removal of the operating handle 11, the sleeves 30 against the Force of the spring 43 towards the bottom 42 of the Press blind hole 32 until the nose 37 of the Sleeve 30 in the extension 36 of the rear shell 27 arrives, and then the nose 37 is twisted to move the sleeve 30 out of the region of the longitudinal groove 34. The sleeve 30 is thus pushed back Condition again through the front shell 26 against one Axial movement secured. Now the gearbox can 3 are lifted out of the recess 10 again.

By housing the threaded holes 29 for Inclusion of the fastening screws for the rosette 13 of the operating handle 11 in an axially displaceable Sleeve 30 becomes the insertion of the gear 3 in the casement 2 not hindered. Because the above Parts are not available perfect centering and assignment of the gearbox 3 to the control handle 11 while saving of machining steps since the rosette holes 18 at the same time in addition to centering the gearbox 3 are used, and because of the installation position protruding sleeves 30 will be sufficient Transport safety of the gear 3 achieved without that the control handle 11 is attached to the casement 2 have to be.

The application of the axially displaceable, with sleeves provided with threaded holes is advantageous for gearboxes of various designs, also for gearboxes, the housing of which Folding surface is placed without a recess in the Channel bottom. It is beneficial if the housing can be supported via the sleeve, for example against a wall of the casement hollow profile, possibly with the interposition of spacers.

Figure 9 shows a further embodiment of the invention that only in terms of Engagement device 50 compared to the embodiment of Figures 1 to 8 differs. In this respect on Figures 1 to 8 and on the associated Described description and below only on the Difference made. The difference is there in that the engagement device 50 as on Edge of the recess 10 supporting back surface 52 of the sliding part 30 'is formed. This means that the two sleeves 30 not with one Bayonet type engagement device 50 is provided, as in Figures 1 to 8, but that each of the sleeves 30 by means of the spring 43 is biased in the disengaging direction and in the Through hole 31 or the blind hole 32 is guided in a longitudinally displaceable manner. A fixation device according to nose 37 and extension 36 is not scheduled. However, the sleeves point an anti-rotation device, for example by means of a corresponding nose 37 can be realized can, which in a corresponding longitudinal groove of the through hole 31 and blind hole 32 protrudes. It is not necessary in the embodiment 9, the sleeves 30 with actuation interventions 40 to be provided.

The engagement device 50 is in the sleeves of the Embodiment of Figure 9 as a back surface 52 formed on a radial extension 53 of the corresponding sleeve 30 is located. Of the Radial extension 53 extends over the side surface 35 of the Housing 22 and protrudes from the faceplate 21st opposite direction. Preferably everyone runs the radial extensions 53 parallel or approximately parallel to the side surface 35 of the housing 22, the word "about" being used because preferably the housing is conical in the direction of insertion is trained. The free end 54 preferably protrudes the rear wall of the housing 22.

In the disengaged state of the corresponding sleeve 30 exists between the radial extension 53 and the side surface 35 of the housing 22 a distance that the Deflection of the sleeve 30 corresponds, that is, this can be shifted along the deflection path and thereby be brought into their engagement position. The bottom is in the engagement position of the corresponding radial extension 53 on the side surface 25 of the housing 22. It is also possible, 22 grooves in the side surface 35 of the housing to be provided so that when taking the engagement the radial extensions 53 of the sleeves 30 in these grooves occur at least in part, causing a correspondingly deep deflection position of the sleeves 30 is created.

Should the transmission 3 according to the embodiment 9 in the recess 10 of the casement 2 are used according to Figure 2, so the Fitter first as a threading and push back aid serving radial extensions 53 with their Pushback surfaces 52 on the corresponding edge of the Recess 20, whereby the two sleeves 30th deflect. In this engagement position of the sleeves can then the housing 22 of the transmission 3 to slide into the position shown in FIG. 1. The sleeves spring into this insertion position 30 automatically off again, as above already in the embodiment of FIGS. 1 to 8 described - a fixation of the transmission 3rd done on the sash 2.

In the end region of the two radial extensions 53 can Actuating grooves 55 on the top, if necessary also on the underside, the radial processes 53 be formed. These operating grooves 55 extend preferably not covering the whole Width of radial extensions 53 to prevent that the edge of the recess 10 in these grooves Insertion process snaps in and so far the Manipulation difficult. The edge distance is the Figure 9 clearly shown. The actuation grooves 55 can by means of the rosette holes 18 a tool, for example by means of a Screwdriver, can be reached and allow one Pushing the sleeves back into the engagement position, whereby the removal of the gear 3 from the recess 10 is easily possible. It is natural also possible to press down the sleeves 30 centrally, to carry out disassembly.
