Definitions

• the invention relates to a clamp fitting for fastening glass panes with a hole in the glass pane
• Clamping screw which has a screw head and a screw shaft.
• connection of glass panes to one another to cover glass fronts or the fastening of glass panes to suitable support elements is carried out regularly via holes arranged in the glass pane. Since the aforementioned bores as well as the fastening elements or connecting elements that enclose them or encompass them are subject to a certain manufacturing tolerance, there is regularly the problem of aligning the bore in the glass pane with the axis of the fastening element or clamping elements. Insofar as the respective connection between the glass pane and the fastening or carrier element allows it, one switches to the fastening or carrier element, i.e. the required tolerance compensation is placed in the fastening or support element.
• European patent application 0 617 190 A1 discloses a connection between two adjacent glass panes, in which the clamping rail is arranged at a distance from the glass pane and the screw shaft of the clamping screw is mounted in the clamping rail with a spherical head.
• U.S. Patent 4,689,928 solves tolerance compensation issues; here, however, the spherical bearing has been moved directly into the hole in the disc. In order to achieve an effective tolerance compensation, it is imperative that the supporting elements adjoining the spherical bearing be designed with correspondingly complex members with flexible members.
• German utility model 93 18 862 discloses a tolerance compensation of the holes between the spaced plates of a multiple insulating glass plate.
• holes of relatively large diameter are provided both in the outer and in the inner glass plate, with the actual clamping screw surrounding the actual screw during assembly Hole space is sprayed with resin.
• Such large bores are undesirable on the one hand for optical reasons, and on the other hand the assembly is correspondingly complex due to the required use of cast resin.
• DE 33 28 338 C2 describes a device for adjusting a first component relative to a second component, which - for example - is to be used for connecting adjacent components of exterior door panels of vehicles.
• the setting of the adjacent components against each other takes place by screwing a spacer bushing which clamps the first component into the second component, a threaded nut part being arranged on the second component for this purpose or the second component itself forming a corresponding flange into which the distance bushing can be screwed. Since at least the second component must have a flange-like extension, such a device for connecting glass panes to one another or for fastening glass panes to suitable carrier elements is not suitable.
• DE 44 36 483 A1 discloses a fastening device for fastening building panels, in which a bolt serving for fastening the building panel is mounted in a through-hole in the through hole of the building panel.
• the ball-joint-like mounting is carried out on both sides of the building plate and against each other screwable clamping jaws, which in turn have spherical support surfaces on which the bolt is supported indirectly via a head screw that can be screwed into the bolt. Due to the ball-joint-like mounting of the bolt or its add-on parts in the through-hole of the building plate, the bolt can execute swiveling movements of several angular degrees relative to the building plate.
• the object of the invention is to provide a possibility for the eccentric mounting of a clamping screw encompassing a borehole in a glass pane, with an exact adaptation of the clamping screw shank to the carrier or connecting element to be connected being carried out with little construction effort and with simple assembly.
• the invention aims in particular at those connections in which there is no or no sufficient possibility for tolerance compensation on the carrier element. This is the case both in the hanging support of glass doors and in the attachment of such glass doors to fixed walls or the like. That is, wherever the screw shaft of a clamping screw has to be screwed into a blind hole, a dowel or the like without possible tolerance compensation. It should also be ensured that the tolerance compensation is possible in all planes running perpendicular to the axis of the screw shaft within the hole in the glass pane. Additional loose parts such as eccentric clamping rings and the like should be dispensed with.
• the clamp fitting according to the main patent has a screw head with a pot-like recess for receiving the screw shaft, which has an internal thread into which an adjusting nut fixing the screw shaft can be screwed in such a way that a retaining flange is located between the pot base, the pot-like recess and the adjusting nut of the screw shaft can be fixed axially.
• the invention designs this teaching according to the main patent in that the adjusting nut on the end facing the pot bottom of the screw head is provided with an elongated hole-like groove receiving the retaining flange of the clamping screw, the bottom of which groove forms an elongated hole for the penetration and the formation of a support flange for the retaining flange Guide of the screw shaft of the clamping screw.
• the additional arrangement of grooves on the retaining flange forming part of the screw shaft can be dispensed with.
• the leadership of the retaining flange in the slot-like groove of the adjusting nut makes it possible to laterally move the adjusting nut and thus the screw head screwed to the adjusting nut while rotating the adjusting nut in the direction of the four possible degrees of freedom, so that an adaptation to the hole in the glass pane and on the other hand, an adaptation to the position specified by the screw shaft is possible if, for example, the screw shaft has to be screwed into a wall plug or into a thread in a plate.
• the retaining flange of the screw shaft can be guided in the slot-like groove of the adjusting nut so that even with a firm clamping of the glass pane between the adjusting nut and screw head, movement of the screw shaft in the direction of the four degrees of freedom is still possible.
• the adjusting nut on its side opposite the slot-like groove has an internal thread into which a spacer screw having a corresponding external thread and provided with a support plate can be screwed; this solution is advantageously used when the distance between the glass pane and a carrier element, for example a wall, is relatively short.
• the adjusting nut has on its side opposite the slot-like groove an external thread onto which a spacing nut having a corresponding internal thread and a support flange for a spacer bush can be screwed; this solution is preferably used when the distance between the glass pane and a carrier element, for example a wall or the like, is relatively large.
• the adjusting nut has a double function. It serves on the one hand to support the holding flange of the clamping screw and the connection with the screw head and on the other hand to connect with a spacing screw or spacing nut which is variable in relation to the adjusting nut.
• Figure 1 is a completed section along the line A-A of Figure 2 and
• FIGS. 2 to 4 show a view in the direction of the arrow Y according to FIG. 1, with the screw head omitted in different assembly situations
• FIG. 5 shows a second exemplary embodiment until FIG. 8
• FIG. 5 shows a side view of the clamping fitting in a section through the pane
• FIG. 6 shows a view in the direction of the arrow X according to FIG. 5
• FIGS. 7 and 8 show two different assembly situations in a view in the direction of the arrow X while omitting the screw head.
• the clamp fitting is used to clamp a glass pane 2 and fasten it to a wall 3.
• the glass pane 2 has a bore 4 which receives the screw head 6 of a clamp screw 5, between the bore 4 and the screw head 6 a clamping ring 17 is arranged.
• the screw head 6 has a pot-like recess 8, which has an internal thread 9, into which an adjusting nut 10 can be screwed.
• the adjusting nut 10 has at its end facing the pot bottom 14 of the pot-like recess 8, ie in the region of its end face 13, an elongated hole-like groove 15 (see also FIGS. 2 to 4).
• the slot-like groove 15 is provided in the area of a groove base 16 with an elongated hole 25 which is penetrated by the screw shaft 7 of the clamping screw 5.
• the slot 15 is circumferentially covered by a support flange 21 borders on which the holding flange 11 of the screw shaft 7 of the clamping screw 5 can be supported. It can be seen in particular from FIGS. 2 to 4 that the screw shaft 7 is guided in the slot 25 with the play denoted by 12.
• the adjusting nut 10 On the side of the glass pane 2 facing the wall 3, the adjusting nut 10 has a contact flange 18, which is supported on the glass pane 2 with the interposition of a glass protection 19.
• an external thread 32 is arranged on the adjusting nut 10, onto which a spacing nut 36 having a corresponding internal thread 33 can be screwed.
• the spacer nut 36 has a support flange 34 on which a spacer bush 35 is supported, which is supported on the wall 3 at the other end.
• the axis 20 of the clamping screw 5 is aligned with the axis 23 of the adjusting nut 10 and thus of the screw head 6.
• FIG. 3 a vertical deviation of the two axes 20 and 23 is shown, i.e. Screw head 6 and adjusting nut 10 are arranged vertically offset with respect to the screw shaft axis.
• Figure 4 shows a corresponding diagonal offset
• the embodiment according to FIG. 5 differs from the embodiment according to FIG. 1 essentially in that the adjusting nut 10 has an internal thread 28 on its side opposite the slot-like groove 15 (see FIG. 1), into which a spacing screw 31 provided with an external thread 29 can be screwed which has a support plate 30 at its free end. Via this support plate 30, the clamp fitting 1 can be supported directly on a carrier element, for example a wall 3. It is also the distance b between the adjusting nut 10 and the spacing screw 31 can be changed.
• FIGS. 7 and 8 show different assembly situations in a manner comparable to FIGS. 2 to 4.
• clamp fitting according to FIG. 1 is assembled as follows:
• the adjusting nut 10 and the spacing bush 35 screwed to the spacing nut 36 have been plugged onto the screw shaft 7 of the clamping screw 5, the latter is first screwed into a wall by means of the hexagon socket 37 via a thread 22, a dowel or the like.
• the adjusting nut 10 with the components assigned to it is displaced by shifting the slot-like groove 15 relative to the screw shaft 7 of the clamping screw 5 such that the axis 23 of the adjusting nut 10 and thus the axis of the screw head 6 is aligned with the axis of the bore 4 in the glass pane 2.
• the clamping screw 5 in the desired manner, i.e.
