Insulating glass fastener

1. A device in glass wall claddings for mounting insulating-glass sheets, each glass sheet having at least two glass slabs which are joined together by a jointing substance, said device comprising:

a retainer member; and

an anchoring member,

wherein said retainer member has an articulated connection to said anchoring member, one of said retainer member and said anchoring member is insertable into the other such that said anchoring member is rotatable from a first position of rest to a second position,

in said first position, said device, upon mounting of said insulating-glass sheet, allows the insulating-glass sheet to be placed in a desired position, and

in said second position, upon mounting of said insulating-glass sheet, said device grips at least one glass slab of said insulating-glass sheet,

wherein a portion of the anchoring member penetrates into said jointing substance of an insulating-glass sheet as the anchoring member of the device is guided from said first position to said second position, in response to the anchoring member being tilted to said second position.

2. A device as claimed in claim 1 , wherein said anchoring member comprises a second part arranged to travel in a groove formed in said retainer member.

3. A device as claimed in claim 2 , wherein said second part of the anchoring member, is joined to said first part by an interconnection device.

4. A device as claimed in claim 3 , wherein said interconnection device is arranged to lock the device in said second position.

5. A device as claimed in claim 2 , wherein said groove is undercut and wherein said anchoring member is arranged for tilting movement about an axis adjacent and along the opening of said groove.

6. A device as claimed in claim 1 , wherein said anchoring member part, which upon displacement of said device from the first position to the second position, penetrates into said jointing substance, has a length along the lateral edge of the insulating-glass sheet that exceeds the spacing between two juxtaposed insulating-glass sheets.

7. A device as claimed in claim 1 , wherein said anchoring member is formed with protruding and a spring-biased device, said device, upon movement of said anchoring member from said first position to said second position, fitting in said second position into recesses of complementary configuration formed on the retainer member.

8. A device as claimed in claim 1 , wherein said retainer member is provided with resilient mouldings arranged to abut against the insulating-glass sheets.

9. A device as claimed in claim 1 , wherein said anchoring member comprises a resilient portion on the face of the anchoring member that in use is turned towards the edge of the glass slab for abutment of said portion against said edge.

10. A device according to claim 1 , wherein said anchoring member is separable from said retainer member.

11. A device according to claim 1 , wherein said articulated connection is a hinged connection.

12. A device according to claim 1 , wherein said anchoring member is rotatable from a first position of rest to a second position of rest.

13. A device according to claim 12 , wherein said anchoring member is separable from said retainer member.

14. A device according to claim 12 , wherein said articulated connection is a hinged connection.

15. A device according to claim 12 , wherein said anchoring member is rotatable from a first unbiased position to a second unbiased position.

16. A device in glass wall claddings for mounting insulating-glass sheets, each glass sheet having at least two glass slabs which are joined together by a jointing substance, said device comprising:

a retainer member; and

an anchoring member,

wherein said retainer member has an articulated connection to said anchoring member, one of said retainer member and said anchoring member is insertable into the other such that said anchoring member is rotatable from a first unbiased position to a second position,

in said first position, said device, upon mounting of said insulating-glass sheet, allows the insulating-glass sheet to be placed in a desired position, and

in said second position, upon mounting of said insulating-glass sheet, said device grips at least one glass slab of said insulating-glass sheet,

wherein a portion of the anchoring member penetrates into said jointing substance of an insulating-glass sheet as the anchoring member of the device is guided from said first position to said second position, in response to the anchoring member being tilted to said second position.

17. A device in glass wall claddings for mounting insulating-glass sheets, each glass sheet having at least two glass slabs which are joined together by a jointing substance, said device comprising:

a retainer member; and

an anchoring member,

wherein said retainer member has an articulated connection to said anchoring member, one of said retainer member and said anchoring member is insertable into the other such that said anchoring member is rotatable from a first position to a second position,

in said first position, said device allows the insulating-glass sheet to be placed in a desired position, and

in said second position, upon mounting of said insulating-glass sheet, said device grips at least one glass slab of said insulating-glass sheet,

wherein a portion of the anchoring member penetrates into said jointing substance of an insulating-glass sheet as the anchoring member of the device is guided from said first position to said second position.
