Definitions

  • the invention relates to a length-adjustable locking device for wings such as windows, doors or the like.
  • the locking device is controlled by a gearbox, which is arranged in the wings mentioned in the frame and actuates push rods in opposite directions, with which the wing can be locked on the two frame sides, which are perpendicular to the wing frame part in which the gearbox with its push rods in one Groove is inserted.
  • DE-A 21 42 085 proposes to assemble the transmission linkage from two telescopically telescoping and mutually fixable rod parts, the mutually displaceable rod parts being fixed to each other only after all the rod parts have been fully assembled.
  • a clamping screw is used, which is (permanently) accessible from the outside and which fixes the two parts of the linkage that are telescopically movable against each other on each side of the transmission.
  • a faceplate can be provided that covers the rebate groove and that has an elongated hole in the area of the clamping screws mentioned, so that even after attaching the gearbox with its linkage and the faceplate on the wing, you can (subsequently) make the fine adjustment of the linkage length .
  • the linkage profiles used for this (U-profile and round bar or C-profile and flat rail or round bar and sleeve, both with thread) are shown in more detail in Suhr in Figures 3 and 5, but complex (not inexpensive to manufacture) and also of considerable strength , so that a recessed groove would be required for the attachment of such an adjustable locking device. The invention seeks to avoid this.
  • a decisive advantage of the technical teaching mentioned is the avoidance of cutting to length by means of a coupling piece which is fixedly arranged at the end on the push rod extending from the transmission.
  • the elongated locking member is immovably but releasably guided and held, the effective length of which is adjustable on the coupling piece.
  • the push rod and locking member overlap more or less and the greater the overlap, the shorter the effective length of the combination of the longitudinally displaceable push rod and the elongated locking member arranged thereon.
  • the maximum overlap of the elongated locking member and the longitudinally displaceable, by the gear controlled push rod is achieved when the inner end of the elongated locking member reaches the offset, which is provided in the push rod not far from the gear housing (claim 1, claim 10).
  • a one-sided or double-sided length variation of the combination of locking member, coupling piece and push rod - symmetrical to the opposite gear - can be provided, or an asymmetrical length of the double-sided locking / pushing elements can be selected (claim 2).
  • both push rods start from one long side (perpendicular to the narrow sides) of the gearbox (claim 9, alternative a).
  • the amount of the cranks is significantly less than the height of the gear (perpendicular to the adjustment plane of the push rods).
  • the gear does not have to be (symmetrically) arranged in the middle of the push rods (claim 2, alternative a, b).
  • the push rods or the locking members can have different lengths so that the gear (as an offset gear) does not come to rest in the middle of the sash frame spar.
  • asymmetry can be brought about, strengthened or adjusted through different overlaps - with or without locking links of different lengths.
  • the push rods can be designed as flat rods (claim 3, alternative a), the associated locking members only having to be elongated, but their geometric cross-sectional shape can take any possible shape, round, flat or polygonal, whereby threaded rods can also be used (claim 3, Alternative b, claim 10).
  • cranking of the push rods comes to lie directly on the gearbox housing or at least close to the gearbox housing when the gearbox has pushed the push rods together, there is an adjustable length compensation between zero and V, which is achieved by the overlap of the elongated locking member and the longitudinally displaceable push rod. . If the distance from the crank to the end of the push rod, where the coupling piece is fixed, is selected as a multiple of the distance that the crank keeps from the gearbox when the push rods are extended, the adjustment range V of the adjusting device can be increased (claim 5).
  • the coupling pieces can be essentially square as "blocks", the width of which should correspond approximately to the width of the push rod in order to be flush.
  • Their dimension in the push direction of the push rods is not critical, but it is considerably less than the max.
  • Their dimensions perpendicular to the adjustment plane of the rods are small, especially in the order of magnitude of the offset or the thickness (cross-sectional dimension) of the locking links.
  • the locking members are cut to length by extensive overlapping of the locking member and push rod.
  • the locking device according to the invention is flat in shape and finds its place in shallow grooves.
  • the locking device can still be adjusted in its longitudinal stroke (engagement width) even after mounting on the sash, because the locking devices on the coupling pieces can be accessible from the outside (claim 7, alternative b).
  • the push rods can be guided through sliding bearings.
  • Angle pieces on the corner area of the wing are suitable as sliding bearings.
  • An angle leg is, for example, sleeve-shaped for receiving the, for example, round locking member.
  • the exemplary embodiment shows a gearbox 1, which can be inserted into a spar of a door or casement frame, into which a handle (not shown) can be inserted and fixed through an opening 2.
  • the bolt 3 is actuated, which engages in a counter bearing on the frame.
  • the two flat push rods 4a, 4b are moved longitudinally in opposite directions starting from the short narrow sides of the gear housing 1.
  • they are provided with longitudinal slots which are guided in corresponding central bolts on the gear housing 1.
  • the push rods are guided essentially in the plane of one longitudinal narrow side, that is to say only on one side of the transmission.
  • the embodiment is constructed symmetrically on both sides. In the following, reference is therefore only made to one side, the description of the other side is obtained if the lower case letters "a” in the following description are replaced by the lower case letters "b" in the reference numbers.
  • the push rod 4a with its offset 5a close to the gear has a block-shaped coupling piece 6a at its free end, which carries a bore 8a approximately in the center, which points in the longitudinal direction.
  • the coupling piece 6a is fixed on the inside of the push rod 4a, the crank 5a is directed outwards.
  • An - in the example - Allen screw 7a serves as a locking device for a locking bar 10a, which has a circular cross section. It is inserted through the bore 8a and fixed with the Allen screw 7a.
  • the locking bar 10a can perform a length adjustment movement which has the maximum amount V. This path corresponds to the distance between the block-shaped connecting member 6a (between locking bar 10a and flat push rod 4a) and the offset 5a in the push rod.
  • the front end of the locking bar 10a close to the drive is in direct contact with the crank.
  • the greatest effective length results when the mentioned inner end of the locking bar 10a comes to rest on the transmission-side inner end of the coupling piece 6a.
  • the locking bar 10a can be adjusted as desired and the gear can accordingly be adapted to all leaf widths lying between these two extremes.
  • the distance G of the crank 5a from the narrow-side end of the transmission 1 is also shown in the illustration.
  • the transmission is in the extended state, in which the nose 3 protrudes completely from the transmission 1 and the push rods 4a, 4b assume their outermost position.
  • the length V is a multiple, in particular a three or four times the length G.
  • the corner guide at the end of the spar, in which the transmission described is installed, is achieved by a sliding bearing 12a.
  • This has an angular shape and two legs 13a and 15a, the leg lying in the plane of the push rod 4a having the guide bore 14a for the locking bar 10a.
  • the other leg 13a can be flat.
  • the sliding bearing 12a is fixedly arranged at the wing corner by means of screws through bores in the flat leg 13a.
  • a threaded rod 11a is used instead of the round rod 10a, which is detachably fixed in the block-shaped connecting piece 6a with the locking device 7a, the locking device 7a can be omitted; instead, the connecting piece 6a has a threaded through hole in the longitudinal direction (sliding direction).
  • the adjustability of the effective length of the connection of the threaded rod 11a and the flat push rod 4a is then obtained by turning the threaded rod 11a.
  • the length of your thread should have at least the longitudinal dimension V for maximum adjustability.
  • a large range of leaf widths is therefore covered with a few threaded rods 1a and round rods 10a. Only a few module pieces are required, which means that costs and warehousing can be reduced, even if the locking device controlled via the gearbox fits a large number of leaf widths. Cutting the locking members 10a, 11a can be avoided in any case, and a fine adjustment after installation can also be made possible.
  • the overall height of the overlap area is low, which is contributed by rectified crank 5a and coupling piece 6a. Both have approximately the "height" of the cross section of the locking bar 10a, 11a.
  • the invention relates to a length-adjustable locking device, as it can be used in windows and doors to lock them.
  • Part of the locking device is a counter-rotating gear arranged in the middle between oppositely longitudinally displaceable push rods which can be actuated via a handle. It is avoided with the invention that the gear linkage projecting on both sides of the narrow sides must be cut or cut to a certain wing dimension. This is achieved in that a coupling piece 6a, 6b is fixedly arranged at the free end of the push rod 4a, 4b and an elongated locking member 10a, 10b, 11a, 11b is non-displaceably but releasably connected to the push rod via the coupling piece.
  • the push rod has a crank 5a, 5b, which is much closer to the transmission 1 than it is to the coupling piece 6a, 6b at the end of the push rod 4a, 4b.
  • the elongated locking member 10a, 10b can be displaced in the coupling piece 6a, 6b when the locking device 7a is released, but it (11a, 11b) can also be rotatably guided in a thread in the coupling piece 6a, 6b.
