Description

Przedmiotem niniejszego wynalazku jest samoczynny zamek do specjalnych ce¬ lów, jak np, do gasnic lub tym podobnych przyrzadów.Znane dotychczas zamki samoczynne sa za drogie ze wzgledu na wielka ilosc skom¬ plikowanych czesci i nie nadaja sie nad¬ to do aparatów obslugiwanych przez nie¬ fachowców, gdyz ich czule prowadzenia i lozyska wymagaja specjalnej pielegnacji.Konstrukcja wedlug niniejszego wyna¬ lazku odznacza sie natomiast wielka prosto¬ ta i nie jest czula na jakiekolwiek szko¬ dliwe dzialania.Na rysunku przedstawiony jest przy¬ klad wykonania wynalazku w przekroju podluznym i w widoku zprzodu.Sprezyna spustowa 1 jest plaska i po¬ siada w odpowiedniem miejscu otwór.Otwór ten sluzy w tym celu, aby haczyko¬ waty koniec przysuwnicy 4 mógl przecho¬ dzic przez sprezyne, a zabek przysuwnicy mógl sie opierac po spuszczeniu na dolnej czesci otworu w sprezynie. Otwór ten u- mozliwia nadto przy spuszczeniu zamka przeskakiwanie zabka przysuwnicy przez sprezyne 1. Sprezyna spustowa posiadaja¬ ca na górnym koncu bolec 2 i przeciwwa¬ ge 3 przymocowana jest dolnym koncem na podkladce w (punkcie 6. Umocowanie oraz sama podkladka w ten sposób sa przewidziane, ze po przekroczeniu nor¬ malnego polozenia sprezyny przy naciaga¬ niu jej powstaje krótsza dzwignia, niz przy spuszczaniu. Powoduje to mniejsze hamo¬ wanie sily bezwladnosci wskutek czego o-siaga sie wieksza sile uderzenia oraz mniejsze zuzywanie sprezyny.Przysuwnica 4 sluzy do przenoszenia nacisku z cyngla 6 na sprezyne 1 i spu¬ szczania jej po najwiekszem naciagnieciu.Spuszczanie odbywa sie w ten sposób, ze haczykowaty koniec przysuwnicy, wyko¬ nany jako skosna powierzchnia, slizgajac sie po sworzniu 5 podnosi przez to do gó¬ ry cala przysuwnice, wskutek czego jej zabek przesuwa sie ponad oparcie w spre¬ zynie i zwalnia ja. W stanie spokoju za¬ bek przysuwnicy wspiera sie na oparciu w otworze sprezyny /, a haczyk przysuwni¬ cy na sworzniu 5. Sprezyna spustowa 1 jest zatem w normalnem polozeniu niena- ciagnieta i wskutek tego zamek nie moze sie spuscic przy nieprzewidzianych wstrza- snieniach.Sprezyna wsteczna 7 sluzy do tego, aby przysuwnice i cyngiel sprowadzac do pierwotnego polozenia. Wykonana jest równiez jako sprezyna plaska i tak umie¬ szczona, ze kierunek jej dzialania na przy¬ suwnice w stosunku do jej osi (umocowa¬ nie w cynglu i krawedz zeba) znajduje sie pod pewnym katem. Osiaga sie przez to równoczesny powrotny ruch cyngla oraz zaskakiwanie zabka przysuwnicy po jej przejsciu poza oparcie w sprezynie. Cyn¬ giel 6 wykonany jest jako jednoramienna dzwignia i posiada przeniesienie okolo 1 do 3-ch. Sworzen 5 sluzy do podnoszenia szyjki haczyka oraz zabezpieczania go w normalnem polozeniu przeciwko cofnieciu. PL PLThe present invention relates to an automatic lock for special purposes, such as fire extinguishers or the like. Hitherto known automatic locks are too expensive due to the large number of complicated parts and are therefore not suitable for the apparatus operated by them. Skilled in the art, since their sensitive guides and bearings require special care. The structure according to the present invention is characterized by a great straightness and is not sensitive to any harmful effects. The figure shows an example of the invention in a longitudinal section and The trigger spring 1 is flat and has a hole in the right place. This hole serves to the purpose that the hooked end of the slide 4 can pass through the spring, and the slide stud can rest on the lower part of the hole when lowered. in a spring. This opening also allows the slider tab to jump over the spring 1 when the lock is lowered. The trigger spring having a pin 2 at its upper end and a counterweight 3 is fixed at its lower end on the washer in (point 6. Fixing and the washer itself are it is foreseen that, after exceeding the normal position of the spring, the lever is shorter when it is pulled, than when the spring is released. This results in less inhibition of the inertia force, which results in greater impact force and less wear on the spring. pressure from the trigger 6 on the spring 1 and releasing it after the greatest tension. Dropping is carried out in such a way that the hooked end of the gantry, made as an oblique surface, while sliding on the pin 5, lifts up the entire gantry, as a result of which its toe slides over the spring support and releases it. springs /, and the slider hook on the pin 5. The trigger spring 1 is therefore in its normal position untensioned and the lock cannot therefore fall off in unforeseen shocks. The reverse spring 7 serves to bring the sliders and the trigger to original position. It is also made as a flat spring and positioned in such a way that the direction of its action on the gantry cranes in relation to its axis (fixation in the cylinder and the edge of the tooth) is at a certain angle. This results in a simultaneous return movement of the trigger and the catching of the slider catch after it passes beyond the spring rest. The trigger 6 is designed as a one-armed lever and has a transmission of about 1 to 3. The pin 5 serves to raise the neck of the hook and secure it in its normal position against retraction. PL PL

Claims

1. Patent claims. 1. Automatic lock for fire extinguishers and similar devices, characterized by having only two flat springs, the directions of action of which are so directed that they form an angle of less than 90 °.

2. Self-locking according to claims The method of claim 1, characterized by having a slider with a hook and a tab which replaces a special safety device to prevent the trigger spring from being lowered from its normal position in unforeseen impacts.

3. Self-locking according to claims 1 and 2, characterized in that any special support is replaced by a hole in the trigger spring through which the gantry passes.

4. Self-locking according to claims A method according to any one of claims 1 to 3, characterized in that when the spring is pulled up, due to its rest against the washer, a lever is created which is shorter than in deflating after exceeding the normal position.

5. Automatic lock according to claims 1 - 4, characterized in that the pin and the counterweight are permanently connected directly to the trigger spring and do not have any special guides, for the purpose of adjusting the impact force as required, the counterweight can be appropriately changed or completely removed.

6. Self-locking according to claims 1 to 5, characterized in that the reverse spring is straight, or, in the absence of space, a curved flat or spiral spring, positioned in such a way that the force acting on the slide hook causes the slide and trigger to retract as well as a ditch. ¬ The chute catch for the trigger in the spring will not collapse.
