#CMT# #/CMT# The unit (26) has a central axle (28) provided with an operating member (30) at an end, and two finger pairs (32, 34) arranged in opposite directions on both sides of the axle, where the unit is made of plastic material. Each pair has an upper finger (36) and a lower finger (38) partially arranged one above the other in a direction parallel to the axle such that the fingers determine a locking space of a plane edge in a superposition part of the fingers. The operating member is elongated in a direction perpendicular to the axle and perpendicular to the direction of the fingers. #CMT#USE : #/CMT# Unit for connecting inner and outer elements of a display panel that is used for displaying a photograph of a classroom or a student, of a rectangular photographic frame. #CMT#ADVANTAGE : #/CMT# The configuration of the unit permits to realize the evolutionary panels of the frame in a simple and inexpensive manner, such that each frame of the panel can be easily withdrawn and can be easily replaced in a simple, convenient, reliable and robust manner, without removing the remaining panels, even if the panel is entirely surrounded by other frames, while permitting to offer desired aesthetic appearance. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a side and plane elevational view of an inner and outer elements connecting unit. 26 : Inner and outer elements connecting unit 28 : Central axle 30 : Operating member 32, 34 : Finger pairs 36 : Upper finger 38 : Lower finger 40 : Rectilinear projection 42 : Projection. |
