Description

one

A device for fixing a door is known, comprising a retainer and a hinge comprising a hinge bracket mounted on the door frame and a hinge bracket mounted on the door hinged together. The latch is made in the form of a curved lever hinged to the hinge of the doorframe with a wavy concave surface, to which, with a spring, the end of the other lever rigidly connected to the bristles fixed on the door.

However, with such a locking mechanism, the device does not provide sufficient reliability of fixing the door under heavy load, ayuokolko fixing reliability is provided by a spring stretching the depth of the grooves in a wave-like curved lever. In addition, the known device allows the door to open at an angle of no more than 90 °, with the result that in the open 1M position the width of the door opening is reduced by the thickness of the door.

The proposed device ensures reliable fixation of the door and maximum ionization of the size of the doorway in the fixed position of the door.

This is achieved by the fact that the retainer is made in the form of a spring-loaded hook mounted on a forever and mounted with the possibility of rotation around its axis, and

a finger rigidly fixed to the bracket, while the hook is mounted on the hinge to form an aperture between them, the diameter of which is equal to the diameter of the finger.

FIG. 1 shows a device for fitting doors, top view; pas figs. 2 is the same front view.

The proposed device contains a loop consisting of a bracket 1, a joint 2 and a hinge 3,

on which is a retainer, made in the form of a hook 4, mounted on an axis 5 and spring-loaded by means of a spring 6, and a finger 7 mounted on a bracket. In this case, the hook 4 and the hinge 3 form an opening 8, the diameter of which is equal to the diameter of the finger 7, and the center of this hole, together with the center of the finger, are located on the same diameter, described from the center of the hinge 1 of it. When the door is fully opened, the hook 4 covers the finger 7, locking the door in the open position. To close the door, press the end of the hook, and it disengages from the finger 7, causing the door to close.
