Telescopic guide. Choice of furniture accessories

One of the most popular types of furniture fittings are retractable systems for boxes. In the manufacture of cabinet furniture with drawers, guides of various modifications, sizes and models are used. Among the many types, one of the best options is the telescopic guide.

Accessories for moving elements of furniture

In past times, it was necessary to make a lot of effort to open and close the box. At the same time, it could skew or completely come off the wooden rails. Modern systems make it easy, smooth and noiseless to open and close any sliding element of furniture, whether it is a heavy chest of drawers or a small drawer of a desk. Telescopic rails There are several types: Roller, ball, bottom mounting, with clamps, door closers, as well as the Metabox and Tandembox systems. The area of application of the latter where high operational loads are planned - kitchen cabinets, workbenches, technological equipment.

Types of sliding structures

Systems for drawers are divided into two main types - ball and roller. With the correct installation and operation, the roller mechanism ensures a smooth opening and closing of the box. In this case, the nomination can be incomplete and complete. The latter option is much more expensive. Ball structures are more complex and expensive. They work silently, are distinguished by their durability and are capable of withstanding heavy loads. Ball or telescopic rails have several modifications. Differ in terms of installation. Can be attached to the side plane of the box, into the groove of the side surface and combined - from below and from the side of the box. The dimensions of the guides vary in length from 150 mm to 700 mm. Super long guides consist of three parts. The width can be from 17 mm to 35 mm. Depending on the size, the system can withstand weight from 10 kg to 30 kg. Constructions with full extension have levers for separating the box from the guides.

The working principle of retractable systems

Telescopic rails for boxes are used in all types of furniture, where there are retractable systems. The principle of their operation depends on the type of guiding devices and the location of the installation. The base for all guides has the same design. It consists of a series of balls that slide along the stamped grooves. Plates are arranged in such a way that, with a minimum of their mass and dimensions, it is possible to move heavy loads to a greater length. The telescopic guide is made of high-quality quality steel, which ensures the durability and reliability of the entire system. The main advantages of the design are high processability, the possibility of full extension of the box with protection against rolling out. In the guides with the door closer mechanism is installed on the bottom of the box and is not visible when extending. For the trouble-free operation of the mechanism, the calculation of the box itself and the correct installation of the structure are important.

Installation of "telescopes"

The telescopic guide is quite simple to install, but requires precision when assembling. It is necessary to correctly calculate the dimensions of parts and the location for their attachment. Between the cabinet and the cabinet of the cabinet should provide clearance (about 12 mm on both sides). The length of the telescopic mechanism must correspond to the depth of the box. Before installation, "telescopes" are divided into two parts. A strictly horizontal line is placed in the center of the side of the box. One of the parts of the mechanism is screwed on this line. Similarly, the part is fastened on the other side of the box. For fastening there are main and auxiliary holes. Oval holes allow you to adjust the guides, shifting them up and down, back and forth. After that, the same marking is carried out on the internal surfaces of the cabinet, taking into account the number of boxes and the height of the front parts. Then the box with the attached carriage is inserted into the system on the cabinet. Smooth and easy sliding of the movable element indicates the correct installation of the system.

Selection of retractable mechanisms

Not all guides are interchangeable. Roller mechanisms and metaboxes have left and right parts. Telescopic guides are the same for the left and right sides. For each type of detail the boxes are calculated in different ways. The telescopic guide is suitable for a chest of drawers in the bedroom, drawers in the children's room. In a writing or computer desk, the usual roller guides are used more often. In the living room are appropriate hidden systems, although they are more expensive. For kitchen furniture, the most suitable systems are METABOX or TANDEMBOX. BOSCH 3-level telescopic guides are successfully used in ovens. Allow to easily move out of the oven multi-level grids and baking sheets.

Telescopic structures have a number of advantages. First of all, this is a long service life. Easy to manage and yet able to withstand a lot of weight. Among the shortcomings is the high price of some types of systems. It is important to know the assortment in order to best combine the characteristics and quality of the product with its price.
