To operate the latch the free side member ofthe panel has opposite arm 17 a hole 20,
and in a simplified form of the invention this hole may beA of small diameter, adapted to admit a'siiiall rod-like implement, such as a wire nail, which when inserted through the hole will engage arm 17 or a filler piece or pad '18"ther'eon', to raise thel'atch 'proper l1,
' here shown,v the hole 2O maybe internally threaded and a tubular screw p21 inserted therein. f This tubular screw providesa center bore through which a nail or similar yimplement may be insertedl to operate the latch in lthe' mannerl above described.
The outer end of the screw'has at'opposite sideskerfs or notches 22 to receive ascrew ydriver `or analogous implement. 'The latchv "may :then be'oplerated by inserting the screw driver bit int e screw notchesand'turning until the inwardl movement of the screw in contact ,withi arm 11' or its lpad-18' releases 'the hook.
WhetherI the latch operating iiieans lcohsists of ,a simple hole or a tubular screw, in
preferred cases I provide the hole or 'bore 20 c, A
ving access to thelat'ch for release of the'latch lvby* anelein'ent movedwithin the aperture,
at 'its outer end with inwardly cut' opposite Aslots or notches-23, s0 that the external'ap- "pearance of` the f hole'or c aperture is similar to that of a 'keyed lock. As otherwise described, the latch operating opening is camouflaged so thatunauthorized oruninf'ormed personswill believethat the panel can-be opened only by the fuse'poff a special key'and willnot make theattmpt, or 'if they do attempt to openf'it by'key manipulation, ysuch manipulation will be ineffective, and such v operating wth a fixed frame member, the
lpanel having -vtherethroughan aperture givunauthorized `persons will ,"'not understand that they latch maybereleased by a"V simple insertion `of a rod or use of a screw driver.
The'upper latch'8a, to cooperate with the upper frame strip 5 and afford added locking security, may beidentical with the'lower latch 8 except that the releasing a'rirr 17 may be omitted; and the two latchesare connected by a linkl 30,^'so that when the lower la'tclifis manipulated 'in the manner above described,
thevvupper latch is simultaneously operated.
Y While the'- complete structure 4 carrying the latches isv above described asf an exhibiting panel, it ,may otherwiseA bei a doorai'- close Aone or more panels'or card exhibiting frames, as shown in` one ofthe abovementioned applications, :and `in such cases the latch mechanismmay be applied to the door.
In certain of the appended` claims therefor y the term an exhibition panel or the-like is in the aperture.
in its broad sense inclusive of a door pivotally mounted in the main frame or casing.
I claim 1. In a structure of the character described, a frame having an opening for an j exhibition panel or the like, a panel pivotally `mounted therein, a latch pivotally mounted at the inner side of the panel and cooperating with a fixed frame member, the latch having'a releasing' arm and the panel vhaving therethrough an interiiall threaded hole, land a screw in the holecon ronting the latch releasing arm for latch release by rotation of the screw.
2. In a. structure ofthe character described,
