    Abstract

    The object of the invention is the hinge for controlled door closing and opening with damper which solves the technical problem of smooth and controlled closing and opening of the door before the end positions of the hinge, i.e. the open or closed position of the door. The damper fit surface (25) and the damper head fit surface (26) are always in contact with two of the limiting surfaces, i.e. two of the following: the damper stop on the housing for closing (21), the damper stop on the housing for opening (22), the damper stop on the guide for opening (23) and the damper stop on the guide for closing (24), whereby the damper (5) in the initial position constantly applies force in the direction of extension, meaning that the damper (5) constantly applies force to increase the distance between the damper fit surface (25) and the damper head fit surface (26), whereas the hinge guide (3) is dimensioned in such a way that the distance between the damper stop on the guide for opening (23) and the damper stop on the guide for closing (24) is smaller than the maximum distance between the damper fit surface (25) and the damper head fit surface (26).

    EXEMPLARY EMBODIMENT

    [0059] The object of the invention in the exemplary embodiment is used for controlled opening and closing of an oven door. FIGS. 1 and 2 show the assembled object of the invention in the position of partial closure of an oven door.

    [0060] FIG. 3 shows a hinge body 6. FIG. 4 shows a hinge guide 3. FIG. 5 shows a damper 5. FIG. 6 shows a connecting link 2, and FIG. 7 shows a latch 1.

    [0061] The complete hinge is shown in a closed position in FIG. 8, in a neutral position in FIG. 9 and in an open position in FIG. 10. One damper 5 is installed in the hinge guide 3. The damper 5 contributes to a soft closing of the door.

    [0062] The hinge comprises: a latch 1, a connecting link 2, a hinge guide 3, a damper 5, a hinge body 6, a spring fit 7, a spring 8, a pivot point of the latch 31 and a pivot point of the connecting link 32.

    [0063] The hinge further comprises: a damper stop on the housing for closing 21, a damper stop on the housing for opening 22, a damper stop on the guide for opening 23 and a damper stop on the guide for closing 24.

    [0064] The latch 1 is rotatable in relation to the hinge body 6 and the connecting link 2. Force is applied to the connecting link 2 through the hinge guide 3, which causes the rotation of the latch 1 in relation to the hinge body 6. The damper 5 is used to limit the movement speed of the hinge guide 3 in certain positions, whereby the damper 5 comes into contact with limiting surfaces through the damper fit surface 25 and the damper head fit surface 26.

    [0065] The contact surfaces of the damper, i.e. the damper fit surface 25 and the damper head fit surface 26, are always in contact with two of the limiting surfaces, i.e. two of the following: the damper stop on the housing for closing 21 the damper stop on the housing for opening 22, the damper stop on the guide for opening 23 and the damper stop on the guide for closing 24. The damper 5 constantly applies force in the direction of extension or to increase the distance between the damper fit surface 25 and the damper head fit surface 26, whereas the hinge guide 3 is dimensioned in such a way that the distance between the damper stop on the guide for opening 23 and the damper stop on the guide for closing 24 is smaller than the maximum distance between the damper fit surface 25 and the damper head fit surface 26.

    [0066] The latch 1 is mounted on the hinge body 6 with a pivot point of the latch 31. The other side of the latch 1, i.e. the side near the latch head, is intended for mounting the door on the appliance and at the same time transferring the load from the door to the appliance, as well as providing the load-bearing function of the door. A door locking part is mounted on the latch 1 to prevent the door from dropping down during closing.

    [0067] It is self-evident that the above described invention can be also used in other particular form not changing the substance of the invention.
