Fixing device for producing an anchoring in panels, especially panels consisting of glass
A fixing device is provided for anchoring in an undercut drilled hole in a panel, especially a glass panel, having an anchor bolt. The anchor bolt has fixing means and an anchoring zone having a portion that widens in cross-section in the direction of insertion. In order to provide such a fixing device having increased resilience, the invention proposes that the anchor bolt having a covering of a resilient plastics material in the region of the anchoring zone and that the anchor bolt be anchored by means of a curable composition.
1. A fixing device anchored in an undercut drilled hole drilled only partially into an undercut portion of a panel, the fixing device comprising:
an anchor bolt comprising fixing means for fixing the panel to a supporting structure, and an anchoring zone having a portion that widens in cross-section in a direction of insertion and in correspondence with the undercut portion, and
a covering of a resilient plastics material that covers the anchoring zone and has a thickness and resiliency such that when the fixing device is anchored within the undercut portion, the covering permits inclination of the anchor bolt relative to the undercut portion of about ten degrees in response to transverse forces,
wherein an outermost cross-sectional dimension of the resilient material is less than an innermost cross-sectional dimension of the undercut hole.
2. A fixing device according to claim 1 , wherein a smallest outer diameter of the covering is smaller in diameter than the portion of the anchoring zone that widens in cross-section.
3. A fixing device according to claim 1 , wherein the covering comprises a silicone-containing plastics material.
4. A fixing device according to claim 1 , wherein the covering consists of a silicone-containing plastics material.
5. A fixing arrangement comprising:
a panel having an undercut drilled hole extending only partially through the panel and comprising an undercut portion; and
a fixing device anchored in the undercut portion, the fixing device comprising an anchor bolt having fixing means for fixing the panel to a supporting structure and an anchoring zone having a portion that widens in cross-section in a direction of insertion and in correspondence with the undercut portion, and a covering of a resilient plastics material that covers the anchoring zone, wherein an outermost cross-sectional dimension of the resilient material is less than an innermost cross-sectional dimension of the undercut hole, and
wherein the covering has a thickness and resiliency such that the covering permits inclination of the anchor bolt relative to the undercut portion in response to transverse forces.
6. A fixing arrangement according to claim 5 , wherein a smallest outer diameter of the covering is smaller in diameter than the portion of the anchoring zone that widens in cross-section.
7. A fixing arrangement according to claim 5 , wherein the covering comprises a silicone-containing plastics material.
8. A fixing arrangement according to claim 5 , wherein the covering consists of a silicone-containing plastics material.
9. A fixing arrangement according to claim 5 , wherein inclination of the anchor bolt of about 10 degrees relative to the undercut portion is enabled.
10. A fixing arrangement according to claim 5 , wherein the fixing device is anchored in the undercut portion by a curable compound.
11. A fixing arrangement according to claim 5 , wherein the panel is a glass panel.
12. A fixing arrangement comprising:
a panel having an undercut drilled hole extending only partially through the panel and comprising an undercut portion; and
a fixing device anchored in the undercut portion, the fixing device comprising an anchor bolt having fixing means for fixing the panel to a supporting structure and an anchoring zone having a portion that widens in cross-section in a direction of insertion and in correspondence with the undercut portion, and a covering of a resilient plastics material that covers the anchoring zone,
wherein the covering has a thickness and resiliency such that the covering permits inclination of the anchor bolt relative to the undercut portion in response to transverse forces; and
wherein the fixing device is anchored in the undercut portion by a curable compound.
