    BUS FOR RECORDING A FREE END OF A LOCK LOCK
    Description
    The invention relates to a bush for receiving a free end of a side-locking closure of a window, a door or the like, with a sleeve that can be arranged in an opening in the floor and a basic body that can be arranged in the sleeve.
    An edge bolt closure is known, for example, from DE 87 11 496 UI. The closure serves, for example, to lock the standing wing of a double-leaf door, so that only the gangway can still be opened. For this purpose, the drive rod, which is located behind the cover rail, is shifted such that the free end of the drive rod protrudes above the wing frame and can engage in the floor, the ceiling or a fixed frame. For receiving the free end of the drive rod, a sleeve is generally provided which is arranged in a corresponding receiving opening in the floor, in the ceiling or in a fixed frame. Conventional bushes or floor recesses are cylindrical, tub-shaped or eccentric. These floor cutouts are installed in the floor by the installer. The problem is to set these recesses so accurately that the function of the door is not disturbed and the lower drive rod can reliably dive into the floor recess.
    To prevent such installation inaccuracies, the floor recesses were often conical and centric or conical and eccentric, trapezoidal or tub-shaped. A major disadvantage of these constructions is that, due to the conical shape of the floor recess while the drive rod is retracted, the door leaf already moves in the opening direction with the value of the cone inclination and can therefore lead to blockages in a panic operation.
    Such a can or floor recess is known from DE 201 12 738 UI. The bush has an eccentric tapered receiving opening for the free end of the drive rod, so that the wing can be held playlessly in its locked position. For adjusting the turning position of the bushing, it has a slot on the floor into which a suitable tool can engage, so that the bushing can be rotated in its receiving opening. However, this slot is interrupted by a bore in which the screw for the spreading mechanism is fitted. Therefore, only relatively high forces can be transmitted through the slot, which under certain circumstances can lead to problems with an inaccurate bore and a bushing jammed in the receiving bore.
    DE 20 2006 008 691 UI discloses a bush for a side lock, which comprises an eccentrically arranged receiving opening for the free end of the drive rod. The receiving opening has a square cross-section and four settings are possible, whereby the free end of the drive rod can always only abut one side surface of the receiving opening.
    DE 20 2010 015 752 U1 discloses a bushing consisting of a base body that receives the drive rod and a ramp that can be shifted.
    DE 10 2010 017 583 A1 also discloses a two-part bus device, wherein the actual bus is, however, telescopically arranged in a base body which is fixed in the floor and can be moved vertically there.
    So far bushings are either glued into the floor in corresponding openings or screwed in by means of dowels. Adjustable bushes are installed according to the current state of the art by means of an adapter part, wherein the adapter part is glued or screwed on. The bush itself is screwed on with the adapter part.
    The disadvantages of the previously known solutions are that with all adjustable solutions either additional work steps such as gluing or sloping are required, or that with a screwed-on bush the fixing screws come loose. Solutions where anchors are anchored by additional components are expensive and are also exposed to the risk of the components coming off and coming loose.
    The object of the invention is therefore to provide a device in which the sleeve can be fixed more easily, that is to say it can be anchored in an opening in an object (threshold, floor, ceiling, without additional means such as dowels or an adhesive connection). and so on), which consists of a solid material such as stone, ceramic, concrete, metal and so on. In addition, the preparatory work of the processor must be kept as low as possible.
    This object is achieved according to the invention with a closure of the type mentioned at the outset, because the sleeve, after placing in the opening in the floor, has an effective inner diameter which is smaller than the outer diameter of the basic body.
    The invention comprises a two-part bushing, comprising a sleeve and a basic body, which is clamped into the floor by means of the sleeve, in order to be able to receive the end of a vertically displaceable locking rod of an edge-locking lock located near the floor. The sleeve is inserted into the bore after a single drilling of the carrier material. When the sleeve is pressed into the borehole, it is slightly reduced in diameter and generates a clamping action in the borehole which renders the usual screwing of the sleeve unnecessary. Therefore, further fastening means can be dispensed with.
    According to the invention, the sleeve is slotted in the axial direction. The sleeve is essentially cylindrical and is formed in the form of a ring segment comprising approximately 348 °. The missing piece of ring segment of approximately 12 °, which extends over the entire length dimension of the sleeve, is provided so that the sleeve can be optimally elastically deformed.
    In an exemplary embodiment, it is provided that the sleeve has an uneven outer surface at least regionally. The uneven outer surface guarantees a good anchoring of the sleeve in the borehole.
    A further embodiment of the invention provides that the sleeve has an outer surface at least regionally that is uneven in circumferential direction. Since the unevenness only extends in the circumferential direction, but not in the longitudinal or axial direction, the sleeve can be placed in the borehole without hindrance. For example, a rubber hammer is used for this.
    In a preferred variant, it is provided that the sleeve has ribs or a toothing at least regionally on its outer circumference, the toothing being, for example, a saw toothing. The ribs are preferably sharp-edged and V-shaped. The saw-toothing prevents the sleeve from rotating in the receiving bore or being rotated.
    In a particularly preferred variant, provision is made for the saw teeth to comprise two areas and that one area blocks rotation in one direction and the other area blocks rotation in the other direction. This ensures that the sleeve cannot be rotated in either one direction or the other, or that it can support turning forces.
    Since, with a slotted sleeve, the free ends flanking the slot are relatively flexible, the unevenness or teeth are in the area of the slot.
    In order to achieve optimum anchoring of the basic body in the sleeve, the basic body comprises at least one protruding part on its outer circumference. With this protruding part the basic body is clamped to or in the sleeve.
    In a preferred embodiment, the sleeve comprises on its inner circumference a first groove receiving the protruding part, which ends on the input side for the basic body. As soon as the protruding part engages in the groove, the basic body is guided to the sleeve firmly anchored in the floor. If the first groove runs in the axial direction, it is ensured that the basic body is also arranged perpendicularly in the sleeve.
    A preferred further embodiment of the invention provides that the sleeve comprises a second groove on its inner circumference, then receiving the protruding portion, when the base body is fully inserted into the sleeve and the base body is rotated relative to the insertion direction. This second groove allows a guided rotation of the basic body in the sleeve, without the basic body assuming an undesirable change in position. The second groove preferably extends in the circumferential direction. This allows, for example, an accurate alignment of the square receiving opening in the basic body for a drive rod with a square cross-section.
    To reliably maintain the base body in a pivotal position once set, the first groove has a greater depth than the second groove. The parallel-parallel introduction of the basic body into the sleeve takes place relatively simply because the first groove has a relatively large depth. In the second groove the necessary force closure is established between the base body and the sleeve. In addition, the sleeve is further spread and, therefore, anchored more reliably in the floor.
    A defined installation depth for the sleeve is ensured in that the sleeve comprises a collar on its side facing the side-locking device that protrudes over the outer circumference of the sleeve. This collar lies flat on the upper side of the floor and has, for example, half a lens-shaped cross-section.
    The can according to the invention can also be inserted into floors with a slanted surface. For this purpose, the collar has a support surface that comes to lie on the floor, which support surface is orthogonal or inclined with respect to the axis of the sleeve. The bush is then further perpendicular to the floor, so that the side-bolt lock, which is also oriented perpendicularly, can be inserted stress-free into the bush. The slope can be fixed, for example 6 ° or with another sleeve 10 °. A wedge-shaped ring can also be placed underneath, which can be rotated relative to the sleeve. This allows the compensation angle to be continuously adjusted.
    In order to be able to easily install the basic body into the sleeve, the end of the basic body to be arranged in the sleeve is chamfered.
    As a result, the basic body centers itself and the sleeve is only spread through the chamfer.
    A preferred variant of the invention provides that the basic body arranged in the sleeve closes in one plane with the sleeve. In another variant, the base body comprises a collar on its side facing the edge lock closure, which collar lies on the sleeve when the base body is arranged in the sleeve. This collar therefore fully covers and covers the sleeve.
    For fixing the bushing according to the invention, therefore, only a single borehole has to be provided and only the sleeve and the basic body are required, so that rapid assembly is ensured.
    Further advantages, features and details of the invention are apparent from the subclaims and the description in which a particularly preferred exemplary embodiment is described in detail with reference to the drawing. The features shown in the drawing, as well as in the description and in the claims, can each be essential to the invention individually or in any combination.

    Figure 1 shows a canister designated as a whole with 10, which can be arranged in the borehole 12 of a floor 14 (Figure 6). The sleeve comprises a sleeve 16 and a basic body 18, the basic body 18 being arranged in the sleeve 16 in the position of use. The diameter of the borehole 14 is chosen such that the sleeve 16 is compressed when it is fitted in the borehole 14. For this purpose the sleeve 16 comprises a continuous slot 20 extending in the axis direction. The free ends 22 and 24 adjacent the slot 20 can thus be moved slightly towards each other. On the outer circumference, the sleeve 16 has a plurality of longitudinal connecting pieces 26 which form a toothing 28 in cross-section, in particular a saw-toothing 30 with a cutting edge 32, which can be seen from FIG. The cutting edge 32 then points away from the slot 20. The underside of the sleeve 16 is chamfered on the outside, thereby facilitating the insertion of the sleeve 16 into the borehole 12. At the top, the sleeve 16 is provided with a collar 34 which protrudes radially over the outer circumference and covers the wheel of the borehole 12 and lies on the top of the floor 14 with its bottom forming a support surface 36.
    The inner circumference surface of the sleeve 16 is provided with a total of three first grooves 38, which run in axial direction or longitudinal direction and have a first depth. They are each time shifted by 90 ° relative to each other and relative to the slot 20, which can best be recognized in FIG. In addition, two second grooves 40 extending in the circumferential direction are provided, the depth of which is less than the depth of the first groove 38. Finally, the upper side of the collar 34 has an adjustment mark 42.
    The base body 18 also has on its upper side a collar 44 which is dimensioned such that it protrudes radially above the collar 34 of the sleeve 16. In the base body 18 there is an eccentrically arranged receptacle 46 for a driving rod of a side lock closure with a square cross-section. This receptacle 46 has four sides 48, which have different distances from the center axis. These are indicated by markings 50. Moreover, portions 52 protruding on the outer circumference surface are provided in the form of obtuse-angled cones, which are each arranged two cones one above the other with a 90 ° distance around the outer circumference. The distance of the cones lying one above the other is dimensioned such that it corresponds to the distance of the two grooves 40.
    When the base body 18 is slid into the sleeve, the protruding portions 52 engage in the first grooves 38. The dimensions of the protruding portions 52 are selected such that they make the sleeve 16 slightly wider. A force cut is therefore generated. When the base body 18 is fully slid into the sleeve 16, the alignment and adjustment of the receptacle 46 with respect to the position of the drive rod takes place. A suitable tool is used for this, for example a square key. The protruding portions 52 thereby engage in the second grooves 40 and widen the sleeve 16 further, so that the teeth 28 chuck in the wall of the borehole 12. The sleeve 10 is now anchored to form and force-tight in the borehole 12.
    Figures 6-8 show three variants of the sleeve 16, the first variant shown in Figure 6 being suitable for flat floors 14, the lower support surface 36 of the collar 34 being orthogonal to the axis of the sleeve 16 expires. In Figure 7, the bearing surface 36 is inclined at an angle of 6 ° and in Figure 8 at an angle of 10 °. Both of these variants are suitable for weak and strongly sloped floors 14.
