Description

The group of inventions relates mainly to the production of furniture, namely to the construction of supports with guide upper rollers for the internal and external doors of the hanging system of the wardrobe. The invention also relates to a method for regulating the position of the named supports with rollers in height.

A support with a guide roller for a sliding door is known, comprising a U-shaped bracket, one side wall of which is designed to be mounted to a sliding door, and a guide roller is fixed to the other (RU 2317391, class E05D 15/06, published 02.20.2008).

The named support can be selected as an analogue of the proposed support with a roller for an external sliding door, consisting of two paintings.

Two running elements are also known, each of which is fixed on a corresponding sliding door leaf for two-door leafs, each of the said running elements being equipped with locking means preventing the roller from being removed from the guide track (RU 2525784, class E05D 15/06, published on 20.08. 2014).

The named running elements can be selected as an analogue for the set of proposed supports with rollers for internal and external sliding doors.

However, both of these analogues do not give an idea about the method of regulating the position of the running elements with rollers in height, which is necessary when installing sliding doors in a room with a floor having irregularities.

At the same time, a roller bearing is known, which comprises: a wheel assembly provided with a guide roller, bushings and an axle, and also means for vertically adjusting the position of the guide roller. The latter includes a horizontal slider mounted with the ability to move horizontally and an adjustment screw connected through a threaded hole. On the side walls of the slider and the housing, holes are provided for moving the aforementioned axis therein. One of these holes is vertical, and the other is a diagonal arrangement. Turning the adjusting screw acts on the slider, which carries out horizontal movement, while the axis, moving simultaneously in the multidirectional holes of the slider and the body, provides height adjustment of the guide roller (RU 62140, class E05D 15/06, published 03/27/2007).

Known support with a roller, providing the ability to adjust the roller in height, has a more complex, bulky and expensive design. It requires preliminary adjustment of the relative position of structural elements (settings) before installing on the door leaf. There is no “neutral” position of structural elements from which up or down regulation occurs (this position should be determined by the collector during the adjustment process after the final assembly of the cabinet, even if there is no uneven floor and no adjustment is required). This process is time-consuming and requires high qualification of the collector, in addition, it requires control of the engagement of the lower corners (they can disengage during adjustment) and takes a lot of time.

In contrast to the known known support with a roller in the proposed method and system, preliminary adjustment of the structural elements is not required, the preliminary additive (tapping holes for mounting screws) is carried out based on the neutral position of the rollers and, therefore, the “adjustment” of the desired roller is carried out up or down as necessary . In the absence of uneven floors, adjustment of the rollers is not required at all. The design of the lower rollers provides reliable engagement in the entire range of adjustment and does not require additional adjustments.

The technical result of the invention is to reduce the material consumption and simplify the design of each of the supports with rollers included in the kit and equipped with means for adjusting their height position, and the method of this regulation is convenient, reliable and easy to install these supports on the respective canvases of the sliding door.

In addition, the set of supports with rollers differs from similar products in minimum dimensions that do not require an additional increase in the distance between the internal and external doors of the sliding wardrobe.

The named technical result is achieved in the invention using the following set of features.

A set of supports with rollers for sliding doors comprises at least one support with a roller for an internal door and at least one support with a roller for an external door, each of which is provided with a mounting element with at least one fixing hole and an adjustment screw hole which is made with the possibility of connection with the support.

The named mounting element is L-shaped, mainly with two mounting holes formed on its long shelf, and an adjustment screw hole formed on the short shelf of this element.

The support with a roller for the inner door is made in the form of a plate with mounting grooves and a hole for the locking element. In the middle of the lower part of the specified plate formed limb with a threaded hole for the adjusting screw.

The support with the roller for the external door is made in the form of a U-shaped bracket with different lengths of side shelves, in most of which mounting grooves and holes for the locking elements are formed, and in its middle part a longitudinal groove is made to accommodate the mounting element. In the middle shelf of the bracket connecting the side shelves to each other, a hole is formed with the side walls in response to the shape of the head of the adjusting screw. This hole is designed to fix the head of the adjusting screw flush with the surface of the middle part of the bracket. In this case, the hole of the installation element for the adjustment screw is threaded.

The method of adjusting the supports with rollers in height using the above kit is that first, the installation element is rigidly fixed to the corresponding door leaf (internal or external), and the corresponding support with a roller (for the internal or external door) is attached to this leaf with the possibility of moving in the vertical direction. After that, turning the adjusting screw, install the support with the roller to the desired height and fix it in this position with the help of fasteners passing through the corresponding mounting grooves and at least one hole of the support under the locking element.

The invention is illustrated by drawings, where in FIG. 1 shows a support with a roller of an external sliding door; in FIG. 2 is a section AA in FIG. one; in FIG. 3 - support with a roller of an internal sliding door; in FIG. 4 is a section BB in FIG. 3.

The support 1 (Fig. 1, 2) with a guide roller 2 for the external sliding door of the sliding wardrobe is made in the form of a bracket consisting of two different-sized side (vertical) shelves: long 3 and short 4, connected by the middle (horizontal) shelf 5. B a longitudinal through curly groove 6 (Fig. 1) is formed in the middle part of the long shelf 3 of the bracket, in which a L-shaped mounting element 7.1 with a pair of mounting holes 8.1 and a threaded hole for the adjusting screw 10 formed on the bent end 9.1 of this element is placed ( fi . 2). A pair of adjusting grooves 11.1 is formed on each side of the longitudinal groove 6 in the shelf 3 of the bracket.

The support 12 (Fig. 3, 4) with a guide roller 13 for the internal sliding door of the wardrobe is made in the form of a figured plate 14 with a limb 15 in the middle of its lower part. The support 12 is provided with a L-shaped mounting element 7.2 with a pair of mounting holes 8.2 and a threaded hole formed on the bent end 9.2 of this bracket for the adjustment screw 16. Two pairs of adjustment grooves 11.2 are formed in the plate 14.

The method of adjusting the height of the position of the supports with the upper rollers on the inner and outer doors of the wardrobe is as follows.

First, install the support with the upper roller on the inner door of the wardrobe. For this, the mounting element 7.2 of the support 12 with the roller 13 (Fig. 3, 4) is rigidly fixed through the holes 8.2 on the door leaf with two 4 × 16 mm screws.

Four screws 4 × 16 are not completely screwed into two pairs of grooves 11.2 (they are baited) so that the support 12 with the roller 13 can move up and down these grooves.

Rotating the adjusting screw 16, the vertical movement (shown by arrows in Fig. 4) of the support 12 with the roller 13 relative to the inner door leaf is carried out within 5 mm (2.5 mm up and 2.5 mm down). This is enough to adjust the height of the inner door of the wardrobe with any unevenness of the floor at the consumer. The amount of movement of the support 12 relative to the door leaf is due to the length of the groove 11.2.

After the final adjustment, a locking element in the form of a 4 × 16 screw (not shown) is screwed into the hole 17.2 to fix the support 12 with the roller 13 on the inner door in a predetermined position and, accordingly, exclude the spontaneous movement of the roller 13 during operation of the sliding wardrobe.

At the final stage, the screws that were originally installed in the grooves 11.2 reach the stop.

Then, in a similar manner, a support with an upper roller is mounted on the outer door of the sliding wardrobe. For this, the mounting element 7.1 of the support 1 with the roller 2 for the external sliding door (Fig. 1, 2) is rigidly fixed through a pair of holes 8.1 on the canvas of the external door with two screws 4 × 16 mm.

Screws 4 × 16 are not completely screwed into two pairs of grooves 11.1 (bait) so that the support 1 with the roller 2 can move up and down these grooves.

Rotating the adjusting screw 10, they move vertically (shown by arrows in Fig. 2) of the support 1 with the roller 2 relative to the door leaf within 5 mm (2.5 mm up and 2.5 mm down). This is enough to adjust the height of the inner door of the wardrobe with any unevenness of the floor at the consumer. The amount of movement of the support 1 relative to the door leaf is determined by the length of the groove 11.1.

After the final adjustment, the locking elements are screwed into the holes 17.1 in the form of 4 × 16 screws (not shown) to fix the support 1 with the roller 2 in a predetermined position and, accordingly, exclude the spontaneous movement of the roller 2 during operation of the sliding wardrobe.

At the final stage, the screws that were originally installed in the grooves 11.1 reach the stop.

The set of supports with rollers, designed for the suspension system of a sliding wardrobe, equipped with means for adjusting these supports in height, differs from similar devices in the simplicity of design with fewer parts, does not require an increase in the distance between sliding doors and ensures reliable operation of furniture.
