Description

Przedmiotem niniejszego wynalazku jest przyrzad do osadzania plytek elastycznych (np. z celuloidu lub ze sztucznego rogu) w ramkach, a w szczególnosci elastycznych szkielek, zaslon do fotografi j, lusterek i po¬ dobnych przedmiotów.Przyklad wykonania takiego przyrzadu uwidoczniono na rysunku, a mianowicie na fig. 1 w widoku zprzodu, a na fig. 2 — w wi¬ doku zboku.Przyrzad ten w mysl wynalazku jest wykonany w ksztalcie obcegów, przyczem ich szczeki 1 sa zaopatrzone w otwory 2, w których sa osadzone trzpienie pienków 3, 4. Pieniek 3 posiada wypukla powierzch¬ nie 5, a pieniek 4 — wklesla powierzchnie.Pieniek wklesly 4 moze byc nieznacznie wiekszy od pienka wypuklego 3.Osadzanie np. elastycznych szkielek w ramkach odbywa sie w nastepujacy sposób.Najpierw miedzy szczekami obcegów u- mieszcza sie ramke; nastepnie miedzy pien- kami 3, 4 umieszcza sie elastyczna plytke o srednicy wiekszej od srednicy ramki, poczem sciskajac ramiona 6 obcegów, uwy¬ pukla sie te plytke, dzieki czemu zmniejsza sie jej srednice tak, ze mozna umiescic ja w ramce.Oczywiscie pienki moga byc osadzone na szczekach obcegów równiez w inny sposób, zapewniajacy latwe ich wyjmowanie, np. moga byc przymocowane do nich zapomo- ca srub. PLThe present invention relates to an apparatus for embedding flexible plates (e.g. made of celluloid or artificial horn) in frames, in particular flexible glasses, photographic curtains, mirrors and the like. An example of such an apparatus is shown in the figure, namely 1 is a front view, and FIG. 2 is a side view. This device, according to the invention, is made in the shape of pincers, with their jaws 1 being provided with holes 2 in which stump pins 3, 4 are inserted. The stump 3 has a convex surface 5, and the stump 4 has a concave surface. Concave log 4 may be slightly larger than a convex stump 3. The installation of e.g. flexible glasses in frames is carried out in the following way. ; then between the flaps 3, 4 a flexible plate with a diameter larger than the diameter of the frame is placed, then by squeezing the arms of the 6 pincers, this plate is bulged, thus reducing its diameter so that it can be placed in the frame. be placed on the jaws of the tongs also in a different way, ensuring their easy removal, eg they can be attached to them with screws.

Claims

Patent claims. 1. Device for mounting flexible plates in frames, characterized by the fact that it is made in the shape of pincers, the jaws of which (1) are connected with stumps (3, 4), with one stump having convex surfaces (5) and the second - concaves.

2. The device according to claim 1, the significant point that the stumps (3, 4) are connected to the jaws (1) separately.

3. The device according to claim 2, the significant point that holes (2) are made in the jaws of the stump shafts (3, 4).

4. The device according to claim 1, the significant area is that the stump (3) having convex surfaces (5) is slightly smaller than the stump (4) having concave surfaces.
