Abstract
Media binder arrangement (10) comprising at least one spring clamp (15) attached to the spine (14) of the media binder. The spring clamp (15) having an interior cavity (19). The interior cavity (19) of said spring clamp (15) is additionally formed with a datum spacer cavity (35) having spacer walls (36, 37) limited from the sides (16, 17) by a bending. The spacer walls (36, 37) having wall surfaces facing the clamp base (18) for holding the datum spacer (30) in abutment with the clamp base (18). Method of manufacturing such a media binder arrangement (10).
Claims12
A media binder arrangement comprising,
- a cover with a front, a back and a spine extending along a spine axis;
- at least one spring clamp attached to the spine, said spring clamp having a first side with a first clamping side edge and a second side with a second clamping side edge, said side edges exerting a spring force towards each other in an activated position;
- the sides being joined with a clamp base at a distance from the side edges thereby defining an interior cavity in the spring clamp, each side having an acute angle with respect to the clamp base;
- a tension sheet mounted inside the cavity and protruding out from the cavity next to each of the respective side edges and firmly attached to the cover;
- a datum spacer mounted inside the cavity holding the tension sheet against the clamp base of the spring clamp;
- wherein the spring clamp is provided with spacer walls, each spacer wall being separated from a respective side by a bend in the spring clamp along an axis being parallel with said spine axis, wherein the spacer walls form a datum spacer cavity in the interior cavity of said spring clamp and wherein the spacer walls have wall surfaces facing the clamp base for holding the datum spacer in abutment with the clamp base and the spacer walls.
A method of manufacturing a media binder arrangement, comprising the steps of:
- providing a cover with a front, a back and a spine extending along a spine axis;
- providing at least one spring clamp configured to be attached to said spine, having a first side with a first clamping side edge and a second side with a second clamping side edge, said side edges exerting a spring force towards each other in an activated position and said sides being joined with a clamp base at a distance from said clamping side edges thereby defining an interior cavity, each side having an acute angle with respect to said clamp base, wherein said spring clamp further is provided with spacer walls, each spacer wall being separated from a respective side by a bend in said spring clamp along an axis being parallel with said spine axis, wherein the spacer walls form a datum spacer cavity in said interior cavity of said spring clamp, and wherein said spacer walls have wall surfaces facing said clamp base;
- providing a datum spacer configured to be held by said wall surfaces in abutment with said clamp base and the spacer walls;
- providing a tension sheet that is attached to said datum spacer;
- inserting said tension sheet and said datum spacer longitudinally into said datum spacer cavity in said spring clamp for holding said tension sheet in said datum spacer cavity;
- and
- simultaneously performing the steps of:
- attaching said tension sheet to said front and said back of said cover, and;
- and
- positioning said spring clamp in said spine of said cover.
