Description

The invention relates to a point holder for with holes provided panels, in particular laminated safety glass panels, Single-pane safety glass plates and insulating glass plates, with a first holding part having a central bore, one Housing with a second holding part arranged on the outside, an axial threaded hole on its front and one axial opening on its back, a bolt with an in the interior of the housing elastically mounted bolt head and a shaft extending outwardly through the opening, and a connecting means between the first holding part and the Housing through a plate hole.

Various point holders for glass plates are known. According to WO-A-99 11884, DE-A-43 42 097 and DE-A-195 15 904 holders are known from which formed a ball joint on the one support plate of the holder is. The ball of the mounting bolt is between two hollow spherical zone surfaces mounted on two against each other screwable components are formed. This ball bearing is expensive and there is a risk that the ball between the storage areas. According to DE-A-195 15 904 therefore suitable means for fixing the desired bearing play, such as glue application or locking pins, suggested the Increase the cost of the joint and when dismantling or maintenance are disadvantageous. Axial damping of pressure surges on the Plate is on the washers between the glass plate and limited to the support plates.

From EP-A-0 655 543, EP-A-0 863 287 and DE-U-298 07 905 Point holder for glass plates known in which the bearing pin on front end carries a flat head, which in a housing between a front and a rear elastic element limited is pivotally mounted. The housing is inside the Glass plate drilling. For mounting the plate on a supporting structure The housings must be inserted into the plate holes Bolts must be attached to the support structure, and then the plate must be mounted on the bolt heads, the Housing chamber is to be closed by the locking ring. Panel mounting therefore requires manipulation in the space between the Glass plate and the supporting structure. Assembly and disassembly of the Plate are therefore time consuming and tedious and can only be used by several Installers are accomplished.

From DE-A-195 19 527 is a point holder of the aforementioned Kind known, the pivot center in a housing outside of Plate hole is located and the one at the front end of the support bolt flat head located between a front and a rear elastic element is pivotally mounted. Because of the transverse displaceability the glass plate the flat head a smaller diameter than the storage chamber has is for vertically suspended facade panels the swivel center shifted from the center line of the holder, whereby the spring elements are stressed on one side. The change of the rear spring element is only possible if this point holder is completely taken apart.

The object of the present invention is to create a Point holder with swivel joint for perforated plates, in particular Laminated safety glass panels, regardless of the inclination, e.g. vertical glass facades, sloping or horizontal Glass roofs and horizontal glass ceilings, can be used. In particular, in applications with vertical or inclined Plate the pivot center of the holder regardless of the plate inclination stay on the center line of the point holder, i.e. Not be shifted by the plate weight. It is also said to be a Point holder with swivel joint for plates can be created, which in Joint optionally allows axial shock absorption, i.e. with or without such shock absorption can be used. Furthermore, a articulated point holder can be created by the assembly and Maintenance of the plates is simplified, especially the installation the plate without assembly work on the holder behind the plate is. Finally, such a point holder should be created which is modular and for example for different ones Plate thicknesses can be used and after removing the joint also suitable for rigid attachment to a supporting structure is. Further advantages result from the following description.

This task is done with the point holder mentioned at the beginning solved according to the invention in that on the back or the front a hollow spherical bearing surface of the housing interior is formed, the center of the ball outside the plate bore is on one side of the bolt head one of the bearing surface corresponding spherical surface is formed and between the other Side of the head and the opposite side of the interior an elastic element is arranged. The hollow spherical The bearing surface has in particular the shape of a hollow spherical zone to a hollow hemisphere or beyond it. The spherical Side of the bolt head has the shape of a spherical zone, whereby this zone up to the cross section through the center of the sphere or can extend beyond. The interior of the case is disregarded essentially cylindrical from the mentioned bearing surface, the cylinder diameter being substantially equal to the ball diameter is the spherical surface formed on this head side. The spherical surface of the head is countered by the elastic element pressed the bearing surface so that the center of the ball of the bolt head regardless of the swivel position of the joint on the cylinder axis (= Central axis of the point holder remains). The swivel angle is determined by the opening angle of the axial opening limited to the back of the case and lies in the area of ± 5 °.

According to the preferred embodiment of the invention The point holder is the hollow spherical back of the interior a threaded bush screwed into the housing. The The housing is open on the back and has an internal thread, in which an axial opening for the passage of the bolt shaft having threaded bush is screwed. The axial opening can have a conical shape that limits the swivel angle. This Embodiment of the point holder can pressure surges on the plate dampen by the axial elasticity in the joint and is therefore for Suitable applications in which the plates are held in an elastic manner is desired, such as for facades and roofs. In this embodiment is the spherical surface on the one adjacent to the bolt shank Side of the head. This embodiment is advantageous also the simple assembly of the plate, since the first Point holder without the plate, the front holding part and the connecting means is mounted on the supporting structure. Only then will the plate attached to the mounted point holder, without this another manipulation on the point holder behind the plate is required.

In another embodiment, the are spherical Back of the interior on the molded rear wall of the housing and the front of the interior by a screwed into the housing Thread cover formed. Also in this embodiment is the spherical surface on the one adjacent to the bolt shank Side of the head. The advantages and uses of this Point holders are essentially the same as those described above Embodiment.

Figure 8 shows an embodiment of the hinge pin for use in differently designed point holders of the invention; and

Figure 9 shows an embodiment of the protective glass sleeve for plates of greater thickness.

The point holder shown in FIG. 1 essentially comprises a housing 1 and a hinge pin 2. The hinge pin consists of a shaft 3, at the front end of which an approximately hemispherical head 4 is formed. The head 4 has a spherical zone-shaped surface 5 adjacent to the shaft 3 and an essentially flat surface 6 facing away from the shaft 3. A projecting pin 7 with a centrally arranged key receptacle 8 is provided centrally on the surface 6. The housing 1 has an interior space 9 which is delimited on the front by a transverse wall 10. In the rear area, the housing 1 has an internal thread into which a ring 11 is screwed. The ring 11 has an approximately hollow spherical zone-shaped bearing surface 11 ^a in the front area and a frustoconical opening 11 ^b in its rear area. As can be seen, the hinge pin 2 with its head 4 with the insert of an elastomeric ring 12 between the surface 6 and the transverse wall 10 is inserted into the interior 9, the spherical zone-shaped surface 5 of the hollow-spherical zone-shaped surface 11 ^{a of} the ring 11 partially abutting. A tubular extension 13 with an internal thread is formed on the front wall 10 of the housing and is surrounded by an elastomeric bushing 14 for protecting the glass plate 17. The housing 1 also has an external thread in the front area, onto which a holding part 15 in the form of a flat threaded ring is screwed, which in turn carries a flat elastomer ring 16 according to DIN 4141, part 15. A laminated glass security plate 17 has holes 17 ^a for the use of point holders. As can be seen, is received in a bore 17 ^a pipe socket 13 having the elastomeric bushing fourteenth Another flat holding part 18 with a central countersunk head bore rests on a flat elastomer ring 19 on the outside of the plate 17 and is pulled against the plate 17 by the countersunk screw 20 screwed into the tubular extension 13, whereby a secure plate holder is achieved. The plate 17 can be pivoted together with the entire point holder relative to the fixedly positioned hinge pin 2 by a limited angle.

The embodiment of the point holder shown in Figure 2 differs from that in Figure 1 by the design of the housing 1, so that only this is to be discussed. The housing 1 is not closed in its rear area by a ring, but is instead formed in the form of the ring 11 of FIG. 1, ie the housing itself has a hollow spherical zone surface 1 ^a and a frustoconical rear opening 1 ^b . To introduce the head 4 into the interior 9, the front wall is designed in the form of a ring 10 ^a , to which the tube extension 13 connects to the front, as in the embodiment according to FIG. The housing has an internal thread in the front area, into which the ring 10 ^{a is} screwed. In this embodiment, the housing 1 is fitted from the front with the head 4 and the elastomer ring 12 and then screwed through the ring 10 ^a to the tubular extension 13. For the rest, reference is made to the description of FIG. 1. The plate 17 is to be considered in the case shown as a horizontal roof plate supported from below, which is axially damped in the joint of the holder.

The embodiment shown in Figure 3 differs from the embodiment of Figure 1 essentially by the shape of the housing 1, the bolt head 4 and the ring 11. The bolt head 4 is pivoted through 180 ° (mushroom shape). Accordingly, the hollow spherical zone surface 1 ^{a is} not formed in the rear area, as in the embodiment according to FIG. 2, but in the front area of the interior. The head 4 also carries a key holder 8 on its front side, so that the bolt 2 can be screwed with a key after removing the screw 20. The elastomer ring 12 is here between the flat surface 6 of the head and the flat surface 11 ^{c of} the ring 11.

The embodiment according to FIG. 4 differs from the embodiment according to FIG. 3 in that the housing consists of a first part 21 corresponding to the front part of the housing 1 in FIG. 3 and a second part 22 corresponding to the rear part of FIG. 1 and the ring 11 of the housing according to Figure 3. The holding part 15 is molded onto the housing part 22. The housing part 21 has the hollow spherical zone-shaped bearing surface 21 ^a , with which the head 4 of the bolt 2 is engaged. The housing part 22 has an annular step 22 ^c , which forms the back of the interior 9, and the frustoconical opening 22 ^b . The elastomer ring 12 lies between the annular surface 6 and the step 22 ^c . While the housing 1 in the embodiment according to FIG. 3 is equipped with the head 4 and the elastomer ring 12 from its rear, head 4 is inserted between the two housing parts 21 and 22 in the embodiment according to FIG. 4, which are then screwed together.

Figure 5 shows the point holder shown in Figure 1 without the threaded bolt 2, the elastomer ring 12 and the locking ring 11. For the purpose of attaching the plate 17 to a wall 23 is in a screw 24 is inserted into the interior 9 and into the housing 1 instead of the ring 11 a ring 25 screwed with flat end faces. On the wall 23, a grooved rail 26 is attached, which contains a sliding block 27 into which the screw 24 is screwed so far is that the point holder is fixed on the grooved rail 26 is. The housing construction of the point holder according to the invention can therefore also be used for rigid attachment.

Figure 6 shows a further use of the invention Point holder after removal of the hinge pin 2, the elastomer ring 12 and the ring 11. In the housing 1 is instead of Ring 11 screwed a thread reducing bushing 28 into which a threaded rod 29 is screwed in with the supporting structure (not shown) is connected, which is also a rigid attachment of the plate 17 results. Instead of that on the plate 17 resting part 18 is a sunk into the plate Holding part 18 'provided with a glass protective sleeve 31. The holding part 18 'is in turn screwed into the tube extension 13 Screw 20 connected to the holder to the housing 1 on the Fix plate 17.

Figure 7 shows a glass plate 17 through the point holder 1 is suspended from a ceiling 23. This is the hinge pin 2 screwed into a spacer 32, which in turn ceiling side via a flange 33 with an anchor rod 34 is screwed. Positions 35 and 36 designate a lock nut or a key attack surface.

FIG. 8 shows the axial section of an embodiment of the hinge pin, the head of which can be varied for the desired embodiment of the holder. For this purpose, the separate head 4 has an axial threaded bore 4 ^a and the bolt shaft 3 has a thread at its upper end, so that the head 4 can be screwed onto the shaft in the position shown or pivoted through 180 °. The key receptacle 8 'is located here on the end face of the bolt shaft.

Since the point holder according to the invention is different for plates Thickness can only be used, its tube extension 13 only a length corresponding to the smallest plate thickness. When used on panels of greater thickness, instead of Bushing 14 with the bushing 14 'shown in FIG. 9 in axial section a stepped bore used. According to the different Such bushes are used for larger plate thicknesses which the length of the narrow bore area of the larger plate thickness is adapted in each case.
