Description

FIELD OF INVENTION

The invention relates to devices for storing, placing, displaying or storing various objects and comprising a plurality of separate shelves, drawers or other containers having similar purpose, placed horizontally above one another. The invention can be specifically applied to a furniture system having a plurality of stacked open or open drawers mounted between two closed-circuit mechanical drive mechanisms at opposite ends of the drawers, which enable the drawers to be rotated in a wheel, selecting the required drawer while maintaining a stable horizontal position.

TECHNICAL LEVEL

As a standard, most furniture has drawers, among other things, to store various items, whether small or larger, such as clothes. Usually the drawers are arranged several or even dozens of compactly apart, placed between horizontal guides or special rails and opened by pulling them forward.

It is not difficult to operate a drawer system that consists of only a few vertical drawers above each other and a low height drawer accessible from the floor. Difficulties arise when such a drawer system consists of a dozen drawers or when they are installed at a higher height. Such a system is typical of modern wardrobes, where the lower spaces are for hanging coats, jackets, jackets, dresses, etc., and various shelves are placed above them. Then, to reach the drawers, especially the ones above, you need to use additional promotional tools: chairs, ladders, or special promotional supports.

This is obviously not convenient as extra furniture is needed and it is not safe.

There have been many attempts to address this problem. For example, United Kingdom patent application no. GB191203424 describes a rotary drawer system in which drawers are carousel-mounted and can be rotated by rotating the drawer to the desired lower carousel position.

Such a drawer system has the advantage that, first of all, the height of the drawer space is advantageously utilized, since the drawers in the carousel are arranged not simply vertically above each other but in a circle, thus almost doubling the number of drawers at the same height, and, secondly, such a system makes it possible to turn the drawers in a circle by turning the necessary upright to the lower reachable position, ie no promotions needed to reach any upright.

However, the disadvantage of such a carousel drawer system is that it requires relatively large space to fit the carousel, where the drawers are arranged in a circle, into the furniture itself.

This problem is solved by the invention described in the international patent application no. WO98 / 42231. This patent application describes a drawer system in which a plurality of drawers are secured on their side surfaces to two closed circuits moving in a closed loop about two gears arranged vertically on opposite sides controlled by a common electric drive. The width of such a chain drive is practically equal to the diameter of the gear to which the chain rotates.

Because the drawers are attached to each side of the chain by their side surfaces, the width (depth) of the entire drawer system is slightly greater than the total width of the two drawers, which makes this drawer system superior to the carousel system described above. However, at the same time, such a chain drive system with only two sprockets limits the width of the drawers used, since the drawers on opposite sides of the single chain contour and at the same height must not touch. If larger drawer widths are to be used, larger diameter teeth need to be used accordingly, and it is technically unreasonable to increase the diameter of the used teeth indefinitely.

Another drawback of a drawer system that utilizes only two drive sprockets at the top and bottom of the system on each side is that there is only one drawer at each rotation position of the system. This means that the space of such a drawer system is not maximized.

THE SUBSTANCE OF THE INVENTION

The present invention improves upon prior art solutions in that the drive mechanism of the drawer system of the present invention consists of a chain moving in a closed contour about four rectangular gears: two gears at the top of the system and two gears at the bottom of the system. The cogwheels, in turn, are provided in the shape of a rectangular trough.

Each side drawer is rigidly fixed to a rolling castor system consisting of four square-mounted rolling casters connected diagonally to each other by rigid levers to provide a location for each drawer fixed to the rolling castor system. On the other side, each of the rolling castor systems is pivotally mounted on a chain of four toothed wheels. The wheels of the rolling system are formed so that each has a groove which rolls the guide rails arranged in rectangular trough profile planes.

A similar chain drive system is also formed on the opposite side of the drawer side surfaces. Between the two drive systems, there are a plurality of drawers mounted at their ends on roller systems with guide rails mounted on rectangular bed profiles, which are driven by chains rotating about four sprockets mounted on the corners of the rectangular bed profiles on each side of the drive.

As mentioned above, the rolling wheels are square, the outer distance between adjacent rolling wheels being equal to the inside width of the rectangular trough profile, which is provided with guide rails, so that the trajectory movement is strictly limited and rectangular.

At each corner of the rectangular drawer movement trajectory, bounded by intersecting right angled rectangular bed profiles, is provided with a metal strip equal to the internal distance between the rolling wheels on that side, which is deflected by its lateral surface from the adjacent rectangular bed from another intersecting rectangular trough profile at a distance equal to the diameter of the rolling wheel. The purpose of the plate is to prevent the system of rolling casters entering a corner formed by intersecting rectangular bed profiles from being tilted, but to direct the rolling castor system so that it has a straight line entering all four wheels at an angle formed by intersecting rectangular bed profiles rectangular trough profile, changing the direction of movement by 90 °. And so - continue to circle through all four corners of the intersection of the rectangular trough profiles.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 illustrates an embodiment of a furniture system of the present invention comprising a plurality of drawers 1 and incorporated into a wardrobe. In the example shown, the lower part of the closet is for hanging clothes and the upper part is for pull-out drawers 1.

With a regular wardrobe, a chair, ladder or other promotion would be required to reach the upper uprights 1.

The present invention solves this problem by using a new drawer drive system illustrated in more detail in FIG. 2-7, in which drawers 1 are attached to a closed chain 2 surrounded by about four gears 3: two gears at the top and two gears at the bottom (Fig. 2, which is a sectional view of the line AA in Fig. 1); two upper gears, two more symmetrically mounted at the bottom). All these drive system elements - chain 2 and gears 3 - are mounted in a rectangular trough profile 4 shown in FIG. 4. The same drive system is installed on the other side of the cabinet.

The drawers 1 are mounted on their side surfaces to the drive chain 2 not directly but via a rolling castor system consisting of four square roller wheels 5 with grooves 6 on their rolling surfaces, diagonally connected by rigid levers 7. Each drawer 1 is rigidly connected to its side surface with a rolling castor system at the intersection of the rigid arms 7

8th

The roller wheel systems are mounted on rectangular trough profiles 4, which are provided with guide rails 9 of the roller system wheels 5 as shown in FIG. 4. As mentioned, the rolling wheels 5 are square, the outer distance between adjacent rolling wheels 5 being equal to the inside width of the rectangular trough profile 4, which is provided with guide rails 9, so that the trajectory 1 of the drawer 1 is rigidly fixed and rectangular. forms.

In order for the rolling wheel system to reach, for example, the intersection angle of the vertical and horizontal rectangular trough profiles 4, as shown in FIG. 7, there is a metal strip 10 at each intersection angle of the rectangular trough profiles 4, which is equal to the internal distance between the rolling wheels 5 on that side and which is offset from the side surface of the adjacent rectangular trough profile; at the end from another intersecting rectangular trough profile at a distance a equal to the diameter of the rolling wheel 5. The purpose of the plate 10 is to prevent the rolling wheel system entering the guide rails 9 from being angled by the intersecting rectangular bed profiles 4 and to direct the rolling wheel system so that it enters a straight line at an angle to the intersecting troughs of all four wheels 5. 4, continue to move smoothly through the guide rails of another rectangular trough profile 9. Fig. 7 shows the direction of the arrow that changes the direction of movement by 90 °. And so on - continue to circle through all four intersection angles of the rectangular trough profiles.

A drawer system consisting of a plurality of drawers 1 fixedly fixed on its side surfaces to a rolling wheel system mounted on rectangular bed profiles 4 and pivotally mounted on a closed chain 2 enclosing four ratchets 3 at the corners of rectangular bed profiles 4 is characterized in that the drawers 1 together with the chain 2 can be rotated in a circle about four sprockets 3 by unscrewing the required drawer into the lower part of the cabinet. The upright system of the present invention can be operated either manually or electromechanically using a remote control.

A drawer system with four rectangles will position the gears surrounded by a closed chain more useful than the prior art chain drive system, by allowing drawers of any width (depth) to be used in the furniture, simply by selecting the required distance between the horizontal gears. In addition, rotating such a drawer system will always keep the drawers in a horizontal position.

It will be apparent to one skilled in the art that the present invention may be embodied by other means of transmitting closed-loop motion 2 wrapped around the guiding elements 3 of the motion, so that a specific description of the present invention is provided provided by the invention.
