Changeable frame

A changeable frame for the presentation of exhibits, the changeable frame comprising:

• a frame element having a height, a viewer's side, a rear side facing away from said viewer's side, and mutually opposite lateral outer and inner surfaces, said frame element surrounding a frame opening for visibly displaying an exhibit to be presented from said viewer's side during use, said frame element having a recess leading from said lateral outer surface to said inner surface and opening into said frame opening for insertion of the exhibit into said frame opening and for removal of the exhibit from said frame opening, said recess being disposed centrally relative to said height of said frame element and said recess having a height being less than said height of said frame element;
• and
• a drawer having a receptacle and being displaceably mounted in said recess for positioning the exhibit, said drawer being displaceable between an insertion position in which the exhibit is visible in said frame opening and a removal position in which said receptacle of said drawer is situated outside said frame element for removal of the exhibit from said receptacle;
• said frame element having a first transverse side portion on a first side and a second transverse side portion on an opposite side, said first and second transverse side portions being respectively oriented transversely relative to said recess in which said drawer is mounted and said first and second transverse side portions having inner sides associated with said frame opening;
• said frame element having a square basic shape as seen from said viewer's side and two mutually parallel longitudinal side portions each having one end being interconnected by said first transverse side portion and another end being interconnected by said second transverse side portion of said frame element, said first and second transverse side portions each having grooves with rectangular cross sections being formed in said inner sides of said first and second transverse side portions;
• a closed rear wall supported by said frame element on said rear side;
• said receptacle having longitudinal and transverse sides being surrounded by edge strips and having a rear side being closed by a bottom, said edge strips having a height;
• one of said edge strips having an outer surface associated with said recess and oriented flush with said outer surface of said frame element surrounding said recess when said drawer is in said insertion position;
• said grooves having a height corresponding to said height of said recess and said edge strips permitting said edge strips to be integrated into said frame element and to jointly produce a flat outer surface with said longitudinal side portions of said frame element;
• said recess having lateral boundaries with run-on slopes providing said recess with a shape narrowing in a funnel-shaped manner in a direction of said frame opening from said outer surface of said frame element at least over part of a depth of said recess;
• said one edge strip associated with said recess having ends assigned to lateral ends of said recess, said ends having respective end portions, and oblique surfaces respectively provided on said end portions, said oblique surfaces having an orientation corresponding to said run-on slopes of said recess and said oblique surfaces lying tightly against said run-on slopes in said insertion position of said drawer.
