Definitions

• the invention relates to a drive rod transmission according to the preamble of claim 1.
• Such drive rod gears already belong to the prior art, for example by EP 1 088 957 A1 and are fastened in or on a fitting groove of a folded edge.
• a gearwheel with a polygonal receptacle is rotatably mounted in a housing and can be pivoted via a shaft (more precisely a polygonal shaft or a polygonal mandrel).
• the gear wheel has a circumferential toothing that is limited to a 90 ° angle and is assigned to recesses of a drive rod.
• the drive rod lies above the gearwheel - based on a folded edge to which the drive rod gear is attached.
• the drive rod In order to keep the dimension with which the drive rod gear plunges into the fold edge low, the drive rod is bent in the direction of the fold edge, that is to say away from the gearwheel. This also applies to a faceplate covering the drive rod, which otherwise runs above the drive rod at the level of the folded edge.
• the gearwheel is supported in a packing which supports the gearwheel in the direction of the bottom of the fitting groove. In the installed state of the drive rod gearbox, this filler body lies partially below the bottom of the fitting groove, which is made possible by a recess in the wing or the groove.
• the object of the invention is therefore to provide a connecting rod gear which can be mounted on the wing with little or no reworking with simple and inexpensive production.
• the invention proposes the realization of the features of the characterizing part of claim 1 in a drive rod transmission according to the preamble.
• an intermediate gear is provided to compensate for the axis offset, which brings about a compensation of the axis offset.
• this intermediate gear can no longer be used due to the gears used.
• Other solutions eg WO 01/25576 A1 are also * suitable for a smaller axis offset, but they still represent a certain amount of effort in the manufacture Use of an intermediate gear can be dispensed with.
• the drive rod can be supported in a simple manner against bending open and the otherwise customary cranking - as stated in EP 1 088 957 A1 - can be much smaller if necessary , Furthermore, the housing can be made much more solid by overlapping the drive rod, since the construction space that is otherwise to be made available for the movement space of the drive rod can be used for this purpose within the housing. Because the gear wheel engages through a longitudinal recess in the faceplate, the faceplate can also be produced without cranking, which reduces the manufacturing costs. This also gives the gear another lateral guidance.
• the housing and the faceplate-drive rod unit can be produced separately from one another and then assembled. It is therefore also possible to deliver the faceplate drive rod unit, which must be adapted according to the length or height of the wing, separately from the housing. The manufacturer of the window or door can then stock the housing in large quantities and order the faceplate-drive rod unit to be adapted as required.
• a simplified manufacture of the drive rod can be achieved if the recesses on the drive rod are arranged in a rack element that can be fastened to the drive rod and the drive rod has an elongated hole recess for receiving the rack element.
• the rack element can be adapted much more precisely to the requirements of the tooth engagement and the material selection can be specified.
• a wear-resistant material is advantageous in the area of the rack element, while the focus is on the easy processing of the material of the drive rod.
• the housing has openings for fastening elements, an additional fastening of the housing to the faceplate can be dispensed with.
• this reduces the manufacturing costs and also reduces the installation space of the drive rod gear, since apart from the fastening of the housing to the wing, a fastening to the faceplate is also to be provided.
• the degree to which the shaft protrudes in front of the folded edge can be influenced if the drive rod has an offset pointing away from the gear. In practical use, the drive rod will have to be bent so far that the drive rod comes to rest near the bottom of the fitting groove, since this minimizes the space required in the area between the sash and frame.
• the drive rod can be guided between the faceplate and a holding plate.
• the retaining plate supports the drive rod against the lifting forces of the gear and thereby prevents the drive rod gear from losing its stroke.
• a closed form of the drive rod gear can also be achieved in this way, which facilitates the supply of lubricant and makes it more difficult for dirt to penetrate.
• a swivel movement of the hand lever at 90 ° is usually sufficient for a connecting rod gearbox for a wing that can only be opened.
• the gear wheel has the shape of an approximately 90 ° angle segment of a circle and is provided with a toothed section along the 90 ° angle.
• FIG. 2 shows the drive rod transmission according to FIG. 1 with the housing partially removed
• 3 shows the drive rod transmission according to FIG. 1 in a longitudinal section along the line III-III in FIG. 4,
• FIG. 4 shows the drive rod transmission according to FIG. 1 in a top view
• Fig. 6 shows a section through the upright legs of a double-leaf window.
• a faceplate is designated by 2 and a drive rod by 3.
• the drive rod gear 1 is used for mounting on a folded edge, not shown here, of a wing of a window or a door.
• the folded edge has a fitting groove in which the drive rod 3 is received and covered by the faceplate 2.
• bolt members attached, which can cooperate with fixedly attached to a frame latch interlocking in a locking position.
• the faceplate 2 lies approximately flush with the rebate edge 18 on a step of the fitting groove 20 (FIG. 3) of the wing and the drive rod gear 1 protrudes in the area of the housing 4 via this rebate edge 18 or the faceplate 2.
• the operating lever also has a polygonal receptacle, which receives the polygonal mandrel 6, which acts as a shaft, at the free end 7.
• the shaft which is referred to below only as a polygonal mandrel 6, can be rotated about the pivot axis 8 via the operating lever.
• the end opposite the end 7 is a polygonal receptacle 109 of a gear wheel 110 assigned.
• the drive rod 3 has a flat rectangular cross section and the pivot axis 8 is oriented approximately perpendicular to the narrow side of this cross section.
• the faceplate 2 as is clear from FIG. 2, has no deformation in the area of the drive mechanism and therefore remains unprocessed except for the production of the recesses visible here, in particular the recess 111.
• the recess 111 is designed as an elongated hole recess and is penetrated by the gear 110.
• the polygonal mandrel 6 connecting the operating lever to the gear 110 lies in front of the rebate surface 18 and - based on the bottom 112 of the fitting groove 20 - above the drive rod 3.
• the gearwheel 110 extends through the longitudinal recess 111 in the faceplate 2 and projects into the fitting groove 20 in which the drive rod 3 is arranged.
• recesses 113 are provided for cooperation with the teeth 114 of the gear 110.
• the recesses 113 of the drive rod 3 are arranged in a rack element 115 which can be fastened to the drive rod 3, and the drive rod 3 has an elongated hole recess 116 for receiving the rack element 115 and for the toothing 114 to pass through.
• the recesses 113 in the rack element are slightly tapered, so that optimal engagement conditions result for the engagement of the toothing 114.
• the rack element 114 can, for example, be formed from sheet metal or can also be produced as a molded part by metal casting. The last-mentioned production, in particular, permits very precise production and low-wear material combinations.
• the rack element 115 is fitted into a crank 117 of the drive rod 3 pointing away from the gear wheel 10, through which the distance 118 can essentially be determined, in which the pivot axis 8 in front of the Folded edge 18 or the faceplate 2 lies.
• the offset 117 is selected such that the drive rod 3 is close but in front of the base 112 of the fitting groove 20. Recesses in the area of the fitting groove 20 are therefore omitted.
• the drive rod 3 is guided between the faceplate 2 and a holding plate 119, so that the drive rod 3 cannot be deflected in the direction of the bottom 20 of the fitting groove 18 in accordance with the lifting forces of the toothing 114. On the one hand, this would result in a reduction in the maximum possible stroke of the connecting rod gear 1 and would also result in a higher operating force of the operating lever.
• a crank 117 of the drive rod 3 pointing away from the gear wheel 10, through which the distance 118 can essentially be determined, in which the pivot axis 8 in front of the Folded edge
• the holding plate 119 encloses and guides the drive rod 3 as a U-shaped cover and thus also ensures lateral guidance of the drive rod 3.
• openings 120 for attachment to the wing.
• These openings 120 are provided on the flange-like ends of the trough-shaped housing 4 and, together with elongated holes in the drive rod 3 and bores in the faceplate 2, permit the insertion of fastening screws of the type which are also used, for example, for fastening the faceplate 2.
• fastening screws of the type which are also used, for example, for fastening the faceplate 2.
• these are already provided in the housing 4.
• the housing 4 is limited to the mounting of the gear wheel 110 and the provision of the threaded holes 5 for the fastening screws of the operating lever.
• the dimensions of the housing 4 can thereby be reduced to a minimum, particularly in the longitudinal direction, since otherwise the arrangement coordinated with the spacing 121 for the fastening screws of the commercially available operating hand levers is also included in the Dimensioning of the offset of the drive rod 3 would have to be taken into account if this would lie in front of the folded edge 18.
• the housing 4 is essentially trough-shaped and sits on the faceplate 2.
• the attachment to the wing is carried out - as already carried out - by fastening screws which are passed through the openings 120.
• fixing pins 122 are provided which protrude from the underside 123 and which can be inserted into bores 124 (FIGS. 1 and 3) of the faceplate 2.
• the housing 4 is designed as a molded part and can e.g. be made by injection molding from metal or plastic.
• the trough is stabilized on the one hand by a web 125 running along the central axis and transversely thereto by the thickenings 126.
• the housing 4 is constructed in a longitudinally symmetrical manner except for the threaded bores 5 and projecting pins 5a which run concentrically thereto. This and the additional ones to be fed in anyway
• Fastening screws can be used to fasten the housing 4 to the wing, for example after fastening the faceplate-drive rod unit. Due to the longitudinal symmetry, the housing 4 can be used both for opening to the right and to the left if the attachment of the housing 4 is not to take place centrally on the faceplate or other components not essential to the invention here on the faceplate 2 in a specific arrangement make the wing necessary.
• the pins 5a allow an additional fastening of the housing to the wing by engaging in bores in the wing which serve to pass through the fastening screws of the operating lever.
• the web 125 is divided into a fork and forms the bearing for the gear 110 with the parallel legs 127.
• the gear wheel 110 When the drive rod 3 is mounted, the gear wheel 110 is thus essentially guided over the polygonal mandrel 6, which is supported on bushes rotatably mounted in the housing 4 and arranged on both sides of the gear wheel 110. If the polygonal mandrel 6 has sufficient stability, these bushings can also be omitted.
• the gear 110 can be produced as a simple disk part inexpensively by punching without collars for storage in the housing 6 or the like.
• the gearwheel - as can be seen from FIG. 3 - has the shape of an approximately 90 ° angle segment of a circle and is provided with a toothed section along the 90 ° angle.
• the operating lever of the drive rod transmission 1 designed in this way also has a movement range limited to 90 °.
• Such an espagnolette 1 is usually used for windows that can only be opened for rotation and therefore - in contrast to a window with an additional tilt-open position - a partial stroke can be dispensed with.
• the quarter-circle segment shape creates two orthogonal edge edges 130 on the gear wheel. In the end displacement positions of the drive rod 3, these are aligned parallel to a base 131 (FIG. 3) of the housing 4, so that the gear wheel 110 at no time during its pivoting movement protrudes above the floor 131.
• the connecting rod gear 1 is mounted in an upright spar 140 of a wing 141.
• the wing 141 is provided with an impact bar 142, which overlaps an adjacent wing 143 in such a way that the impact bar 142 covers the wing 143 - the so-called faceplate - and covers a gap 144 located between the wings 141, 143.
• the blow bar 142 is on the visible inside surfaces 145, 146 of the middle ones Wing spars 140, 147 are arranged so that they are approximately in the center of the overall view.
• the control lever 148 which receives the polygonal mandrel 6 in a receptacle 149, is attached to the blow bar.
• the control lever 148 is attached via a rosette 150, which rotatably supports the control lever 148.
• the polygonal mandrel 6 also penetrates the blow bar 142 approximately in the middle and this overall lies in front of the folded edge 18 of the wing 141.
• the pivot axis 8 of the gearwheel 110 is thus also in front of the folded edge 18, the toothing 114 of the gearwheel 110 pointing in the direction of the base 112 of the fitting groove 20.
• the drive rod 3 lies between the base 112 and the swivel axis 8 or the polygonal mandrel 6.
• means for converting the rotary movement of the polygonal mandrel 6 and the swivel axis of the gearwheel 110 can therefore be used - for example as in EP 0505678 A1 or WO 01 / 25576 A1 described - not applicable.
• the direct connection is therefore less expensive and reduces the inevitable slip due to the large number of mechanical connections, which leads to a reduction in the practically executable stroke of the drive rod drive.
