Definitions

  • a padlock having an inverted U-shaped string is widely marketed and used in daily life, but the long leg of the two legs of the string can slide freely in the main body, but does not detach from the main body.
  • the short leg of the string is provided with a notch for locking, and the tip of the locking latch is pressed by the locking notch on the short leg with the swinging provided behind the locking latch to lock the string.
  • Padlocks have a single locking latch, two locking latches, and an inverted U-shaped padlock because they have a simple structure and can be manufactured relatively inexpensively, and to increase the safety and strength of the lock.
  • Locking recesses are provided on the two legs of the string to lock the ball by pressing the locking ball in the body against the recesses, and those provided with various mechanisms are commercially available.
  • the long leg of the inverted U-shaped string can be freely slid inside the main body, but is incorporated into the main body so as not to come off from the main body, and the short leg of the string is provided with a notch for locking
  • Padlocks are widely used, in which the locking latch is pressed by a spring provided behind the locking latch into a locking notch on a short leg to be locked.
  • Padlocks are often used in relatively important places, but they are also used in important places such as preventing theft of warehouses and material storage areas, and preventing entry into restricted areas. A defect that unlocks with a slight impact can cause a major accident.
  • the present invention relates to a padlock having an inverted U-shaped string, and at least one of the legs of the string has a notch for locking, and the tip of the locking latch is pressed into the notch to be in a locked state.
  • the purpose of Naru Padlock is to provide a padlock that does not unlock even if a shock of about human power is applied to the side of the long leg side of the main unit while the padlock is suspended. Disclosure of the invention
  • the present invention provides a locking notch provided on an inverted u-shaped string leg of a padlock and a projection provided at a tip of a locking latch, and the tip of the locking latch is pressed when the locking notch is pressed. Both projections engage each other. Further, according to the present invention, since only a projection is provided on the conventional latch for locking the padlock and the notch for locking, the intended padlock can be obtained in the same manner of using the conventional padlock of this kind. I can do it. BRIEF DESCRIPTION OF THE FIGURES
  • FIG. 1 is a front view of a partial cross section of the padlock of the present invention.
  • 11th is a front view of a partial cross-section showing the locked state of the padlock of the present invention, which is provided at the tip of a locking notch projection 2a provided on the short leg 2 of the string and a locking latch 3.
  • the shape and mechanism other than the projection 3a are exactly the same as those of a conventional padlock of this type.
  • the locking latch 3 moves in the direction in which the impact is applied only to the main body and the strings.
  • the latch 3 for locking is released for a moment from the notch for locking as it moves a little later than the entire length of the string-the entire string is always pushed away from the main body by the compression spring at the tip end of the long leg 1 So unlocking.
  • the padlock of the present invention does not release even if a shock of about human power is applied to the long leg side, and the structure of the padlock is only the addition of two projections to the structure of the conventional padlock. It can be made almost in the same way as it is, and can provide a more secure padlock.

Abstract

Un cadenas classique est ainsi construit que le bras le plus long de l'arceau inversé en forme de U est mis en place dans le boîtier de façon à pouvoir librement glisser à l'intérieur de celui-ci mais sans pouvoir s'en séparer, que le bras le plus court de l'arceau est pourvu d'une encoche d'arrêt servant au verrouillage et que la pointe d'un loquet de verrouillage se pousse dans l'encoche d'arrêt pour se mettre en position de verrouillage. Ce type de cadenas classique présente des défectuosités en ce sens qu'il peut suffire d'un seul coup, porté avec toute la puissance que peut développer un homme, sur une surface latérale du boîtier du coté du bras le plus long pour le déverrouiller. Le fait de ménager une saillie (2a) dans une encoche d'arrêt servant au verrouillage et une autre (3a), dans la pointe d'un loquet de verrouillage, de façon à ce qu'elles (2a, 3a) puissent s'engager l'une dans l'autre pour se mettre en position de verrouillage permet d'obtenir un cadenas impossible à ouvrir même sous l'effet d'un coup porté avec toute la puissance que peut développer un homme, sur une surface latérale du boîtier du cadenas du coté du bras le plus long.
