RU2328584C2 - Loop unit of metal box - Google Patents

Abstract

FIELD: construction.

SUBSTANCE: loop unit includes vertical stand with hole, rotation element, holed wall bracket for axle fixed on rotation element and axle. Axle is made with unbent end having at that G-shaped form. Rotation element contains hole made in plane of its rotation. Wall bracket is fixed on rotation element so that rotation element holes and wall bracket are located concerning each other. Radial groove made on wall bracket provides axle unbent end fixation. Axle fixation provides support in form of lobe turning axle unbent end. Axle is located in hole of box frame or safe with the help of plug.

EFFECT: technology improvement of loop unit construction and decrease of net cost of its production.

Description

The invention relates to furniture fittings and can be used in metal furniture for hanging doors on the body of a metal cabinet or safe.

Known patent RU 2162267, publ. 20/01/2001, in which a hinge assembly for hinging a door of a metal cabinet is disclosed. The device described in the indicated source comprises a rack with a blind hole, a door, a bracket fixed to the door with screws and having a vertical hole for placing an axis in it, a straight axis and a handle fixed to each other with a pin, and also a coil spring, push axis. Patent RU 2162267, publ. 20/01/2001, selected as a prototype of the claimed invention.

The design disclosed in the prototype is characterized by low manufacturability due to the fact that it includes many structural elements, nomenclatures of materials used and technological operations used in the manufacture of these elements.

The technical result achieved by the present invention is to increase the manufacturability of the design of the hinge assembly and reduce the cost of its manufacture.

The technical result is achieved by the fact that in the design of the hinge assembly (Fig. 1) there are no threaded elements and springs. Door assembly and hinge can be carried out without a special tool. In turn, the fixing of the axis in the body of the hinge assembly occurs due to the elastic properties of the material of which the bracket and door are made.

The essence of the claimed invention is illustrated by the images and consists in the following.

The hinge assembly (Fig. 1) includes a static element - a vertical rack, or the case of a metal cabinet or safe (not shown), a rotary element (1) with an opening (2), which can be the door of a metal cabinet or safe, an arm (3 ) with a hole (4), mounted on a rotary element (1), and an axis (5) with a bent end (6).

Distinctive features of this loop unit are that the rotary element has an opening (2) made in the plane of its rotation (rotation).

The bracket also has an opening (4) and is mounted on the rotary element so that the holes of the rotary element and the bracket are aligned, and the axis has a bent end (6) and, accordingly, is made L-shaped. When mounting the axis inside the hinge assembly, the axis is sequentially inserted into the holes of the bracket (4) and the rotary element (2), and then into the hole of the rack or cabinet body (not shown). In addition, the bracket has a groove (7) and a stop (8), through which the axis, sequentially inserted into the above holes, is fixed with its bent end in the looper assembly both from turning and from longitudinal displacement along the axis of these holes.

In a preferred embodiment, the hinge assembly, the bracket and the rotary element are made flexible or stamped from sheet metal blanks. The bracket is fastened to the rotary element by spot welding or gluing. In turn, the fixing groove on the bracket may have a radius part, i.e. is limited by an arc of a circle, and the bracket stop can be made in the form of a tongue, compressing the bent end of the axis, thus creating additional fixation of the axis in the looper assembly.

The axis can be made from a section of a calibrated rod of constant cross section, which is then given a L-shape by bending, in addition, to facilitate the insertion of the axis into the holes, the latter can have a chamfer (9).

In the assembled state, the axis fixed in the manner indicated above performs the function of a stiffener, preventing mutual displacements of the bracket and the rotary element, which is especially important in the manufacture of the blanks of the above elements from sheet metal.

For a more clear understanding of the essence of the claimed loop node assembly sequence is illustrated in figure 2-5. Where figure 2 shows a fragment of a rotary element (doors of a metal cabinet) with a bracket mounted on it. Figure 3 illustrates the moment of insertion of the axis into the holes of the loop assembly. Figure 4 shows a looped assembly with a bent axis end fixed in a radial groove and a stop; in turn, Fig. 5 shows the final axis fixation in an arm by compressing a stop made in the form of a petal around a bent end of the axis.

Claims (3)

1. A hinge assembly comprising a vertical strut with at least one opening, a rotary element, a bracket with an opening for placing an axis therein, mounted on the rotary element, and an axis, characterized in that the axis is made with a bent end, the rotary element comprises a hole made in the plane of its rotation, and the bracket is mounted on the rotary element so that the holes of the rotary element and the bracket are aligned with each other, while the stop made on the bracket bent around the bent to gloss axis, and a groove portion having a circular arc shape, provide for a locking axis beveled end, preventing it from turning and longitudinal displacement. 2. The looper assembly according to claim 1, characterized in that the bracket is made by a stamping operation from a sheet blank. 3. The looper assembly according to claim 1, characterized in that the bracket is fastened to the rotary element by spot welding.
