Blocking device for door

Abstract

The invention relates to a device apt to guarantee the stable blocking of a rotary or sliding door with respect to a fixed surface or frame. The device is of the type consisting of a male element and of a female element. The female element is shaped so as to house the male element in an easy detachable way and retain the male element. According to the device, the female element comprises a pair of mutually spaced-apart, parallel, elastic wings, projecting from a support base. The male element consists of a substantially spherical knob having a diameter slightly larger than the distance between the elastic wings, so that the spherical knob is apt to snap engage between the elastic wings. Moreover, the device also comprises square-wing-shaped position adjustment means associated with the base of the female element and / or with the knob of the male element, and convenient fastening means in the shape of a single fastening screw.

Description

technical field [0001] The present invention relates to a so-called "door latch" device, ie a device which facilitates secure locking of a door relative to a surface or a fixed frame or another door, but which at the same time is easy to disengage, said device being fixed to Structurally, the devices are both hinged to the structure, for example to a protective device of a piece of equipment, on a machine wagon or on a cabinet. Background technique [0002] Devices of this type exist on the market, said devices notably consisting of a male element and a female element, wherein at least one of the two elements has a spring-type fastening to allow snapping into each other and only Disengagement is achieved by the disengagement force applied by the operator.

[0003] Prior art structures made like this, while potentially useful, are often inconvenient and require special care in the manufacturing steps, as these devices are small in size and can become stuck under extreme environmental conditions, and are often inconvenient during the installation step. Special attention must also be paid in the , because special care is also required when recording the mutual position of the individual components
