Set of shapes for retaining a glass plate, including a first shape (10) having a base plate (11) from which project columns (12a, 12b) between which define a longitudinal channel (13), having at the upper end of each column a longitudinal groove (14, 15).
Second shapes (20) arranged vertically aligned on each column of the first shape, this second shape having at its lower end an appendix (22) complementary to the groove (14, 15); presenting the upper end of the second shape on its edge of its internal face a longitudinal recess (27′) that determines the means of seating and securing a third shape (30).
Said third shape each has an upper surface (32, 32′) that sits on the upper end (27) of the second shape, with a longitudinal fold complementary to the longitudinal recess (27′) of the second shape and within which it sits in retention. The upper surface (32, 32′) projects downwards attached to the external surface (12, 24) of (10, 20) covering the joint between them.
The lower end of each third shape forms at the lower end a longitudinal “L” seat (38) turned towards the external face of each column of the first shape.
A fourth shape (40) is placed on each side of the corresponding column of the first shape and has a substantially horizontal wing (42) at the free end of which has a longitudinal projection (43) that seats in connection with the longitudinal recess seat (27′).) of the third shape: said horizontal wing (42) is continued by a section of shape (45) partially attached against the external face of the respective column up to where a continuous concave surface (47) projects facing a hosted light source in (39h).
