Abstract
A striker for a fixed frame includes an opening adapted to accommodate a latch member of an opening leaf fitting. The striker includes a base that can be fixed to the fixed frame and an insert including an opening which can accommodate the latch member. The base includes an opening forming a housing for the insert.
Claims12
A striker device for a fixed frame associated with a leaf carrying a latch member having a median axis and being adapted to be accommodated in said striker device, said striker device comprising:
- a base constructed to be received in a predetermined position in a predetermined hole of said frame, said base having a plate-like web through which is arranged a first opening extending between substantially parallel main edges thereof, said first-opening having a first median axis between said main edges, said first median axis being adapted to have a predetermined fixed position on said fixed frame;
- and
- an insert constructed to be matingly engaged at a predetermined place in said first opening between said main edges so that a median axis of said insert is coincident with said first median axis of said first opening and is adapted to have a predetermined fixed position on said fixed frame, said insert having a second opening adapted to accommodate said latch member and extending between a first lateral wall and a second lateral wall substantially parallel to each other, said first and second lateral walls being adapted to be introduced in said first opening between said main edges and a flange extending from said first and second walls and adapted to cover said plate-like web substantially along said main edges of said first opening, a portion of an outside face of said first and second walls, close to said flange, being adjacent to and mating with a respective main edge of said first opening, said first and second lateral walls including lug means adapted to be introduced through said first opening and to matingly engage said main edges of said first opening in order to grip said main edges between said flange and said lug means, said second opening having a second median axis between said lateral walls, wherein a predetermined fixed thickness of said first lateral wall is equal to or different from a predetermined fixed thickness of said second lateral wall at least at said portions of said first and second lateral walls adjacent said main edges by a predetermined thickness difference so that said second median axis is offset by a predetermined offset distance from said first median axis in a direction substantially perpendicular to said first and second lateral walls, said predetermined offset distance being such that said second median axis is adapted to be directly aligned with said median axis of said latch member when said latch member is accommodated in said second opening in said insert to contact said base.
A striker device system for a fixed frame associated with a leaf carrying a latch member adapted to be accommodated in said striker device system, said striker devise system comprising:
- a base constructed to be received in a predetermined hole of said frame, said base having a plate-like web through which is arranged a first opening extending between substantially parallel main edges thereof, said first opening having a first median axis between said main edges;
- and
- a plurality of inserts, each of said plurality of inserts being constructed to be matingly engaged at a predetermined place in said first opening between said main edges, each of said plurality of inserts having a second opening adapted to accommodate said latch member and extending between a first lateral wall and a second lateral wall substantially parallel to each other of said plurality of inserts, said first and second lateral walls being adapted to be introduced in said first opening between said main edges and a flange extending from said first and second lateral walls adapted to cover said base web substantially along said main edges of said first opening, a portion of an outside face of said first and second lateral walls close to said flange being adjacent to and mating with a respective main edge of said first opening, said first and second lateral walls including lug means adapted to be introduced through said first opening and to matingly engage said main edges of said first opening to grip said edges between said flange and said lug means, said second opening having a second median axis between said lateral walls, the thickness of said first lateral wall being equal to or different from the thickness of said second lateral wall at least at said portions of said first and second lateral walls adjacent said main edges by a predetermined thickness difference so that said second median axis is offset by a predetermined offset distance from said first median axis in a direction substantially perpendicular to said first and second lateral walls, wherein each one of said plurality of inserts has its second median axis offset from said first median axis by a predetermined offset distance which is different from a predetermined offset distance corresponding to any one of the other ones of said plurality of inserts.
