FIELD OF THE INVENTION The present invention relates to a drawer-like element for use with own or non-proprietary rolling guides, particularly for office furniture but other drawer furniture.

Λ In the furniture industry, rolling guides are used to facilitate the movement of heavy-duty drawer brackets, which can be used to convert the load slip friction to a significantly lower rolling resistance by using mechanical elements.

According to current practice, both drawer parts and rolling belts are separate semi-finished products, which are often not manufactured by the same manufacturer. In general, both elements are known as a semi-finished product in a wide range of sizes, but a drawer of a certain size can only have one size roller and vice versa. This means that they are bound to one another.

The drawer is usually made of wood, metal or plastic. The current standard pair of telescopic rolling telescopes is metal or metal-plastic, but more recently also injection-molded plastic.

The so-called. a telescope is made up of two halves with rolling elements, which are organically connected and at the same time can be moved together. The connection between the cabinet element or table body and the drawer element is secured by one of the telescopic halves being mounted on the drawer and the other being mounted on the wall of the cabinet element or table body by a bolted or firmly mounted mechanical solution. This also means that there is a gap between the cabinet wall and the drawer sides that corresponds to the thickness of the telescope cable - that is, the dead space - which is called the so-called. they cover the front of the furniture with a front panel.

Usually both the telescope and the drawer element are suitable for carrying the load, but the weak point of such a system - and also the determining factor of the drawer plate load capacity - is the way of attaching the telescope halves to the furniture side and drawer bracket. In the furniture industry, in practice, 3 -4 mm 2-3 mm, 10-15 mm long wood screws are used to fix the telescope, both at the loose structure - the chipboard - at the furniture side and at the drawer element. The frequent, frequent dynamic use of the drawer-like elements of the furniture for their intended purpose primarily invokes or attacks the said anchoring points, causing them to loosen their function prematurely.

Due to a misguided quality control approach, both roller lines and drawer components are mechanically oversized by the manufacturers, which results in higher commodity prices, which is sensitively reflected in the commercial price of the finished product.

It is an object of the present invention to overcome the difficulties and drawbacks described above, while providing more advantageous drawer components.

The task, taking into account today's furniture industry technology as well as design technology, is to design a structure that will serve as a drawer for its drawers and auxiliaries to the furniture side. - without telescopic elements, rolling lines - provides all the advantageous properties 2 of known known telescopic telescopes, while at the same time providing significantly more favorable volume and functional utilization. The design reduces installation costs and the cost of purchasing an unavoidable pair of current telescopes, which can reduce the cost of each branch by up to 50%, both in the furniture industry and in other industries - for example. for electrical module systems.

The object of the present invention is, for example, to provide rolling drawers on the drawer side drawers for furniture, e.g. , or while pushing. »

The roller tracks are preferably made in one piece with the drawer sides by injection molding.

On the roller conveyors, an end positioning section may be provided at the front end of the drawer bracket, and a lifting section may be provided near the rear end of the drawer bracket and, for stiffening reasons, may have raised ribs from the drawer side.

Injection technology allows the drawer sides to be designed with a heavy duty inertial design.

Depending on the purpose, within the account pages, e.g. with a vertical groove for storing the filing system.

In one preferred embodiment, the support rollers and roller tracks are located above the drawer rollers and the U-shaped roller guide receiving them, while in another, also optionally preferred embodiment, below.

In the drawer element of the present invention, the roller shoe design ensures that the drawer strap is engaged when extended and closed. The U-profiles that guide the drawer rollers also prevent it from tipping over when it is pulled out.

By placing the roller tracks, it is possible to create a horizontally divisible design with a drawer slide system inside the drawer.

Injection technology also makes it possible to make the groove for the drawer lock in the side wall, also made of the material of the drawer element. This eliminates the need for additional fitting items, and further reduces the cost of account draw.

The front of the drawer tab, also made from its own material, can be used with protruding pins to secure the drawer-front panel, which will further reduce installation costs. It should also be noted that the design of the drawer element made of plastic according to the front surface may even omit the drawer plate.

The interior assembly of the furniture, if desired cabinet, which at present requires considerable manual labor, can also be simplified, since the design of the bore of the roller pins can be fitted into a machine technology series without the need for technological time, by serial drilling.

The U-profile roller guide guiding the drawer roller can be extruded as a semi-finished product, e.g. can be made of aluminum with suitable impact arms. In this way, its impact groove can also be made using continuous machine technology, and it provides load parameters of a magnitude higher than the currently used wood screw fixing method, while also ensuring distributed distribution of the load.

The drawer-like elements of the present invention have a simpler design than telescopic drawer drawers of today 's design, can be manufactured with advanced manufacturing technology, at significantly lower cost, with better mechanical parameters, in industrial serial production.

It should also be noted that the drawer roll profile according to the invention is made of another material, e.g. metal and function -pl. It can also be sprayed onto tray elements or can be retrofitted as stand-alone rolling guide. All design solutions have significant economic advantages over ina rolling stock, with the appropriate choice of materials, of course.

The invention will now be described in more detail with reference to its exemplary embodiments, of which:

Figure 1 is a schematic side view of a drawer according to the invention:

Figure 2 is a sectional view illustrating the wiring system of the drawer shown in Figure 1:

Figure 3 shows a drawer corresponding to another embodiment, in the same manner as Figure 2.

Referring now to Figures 1 and 2, a drawer track 3 is formed on the drawer side 2 of the drawer element 1 for a support roll 5 which is pivotally secured to the cabinet side 4 by a ribbed roll pin 10. It can be clearly seen in Figure 1 that the roller track 3, which is substantially parallel to the drawer side 2 of the drawer element 1, is provided with an end positioning path section 3a near the end face of the drawer element 1. It is also shown that near the rear end of the drawer element 1 opposite to the front panel 9, the track 3 has a lifting section 3b. This lifting track section 3b plays a role in lifting and lifting the drawer element 1, since the support roller 5 reaches this lifting track section 3b, facilitates and facilitates the drawer roller 7 secured to the drawer side by means of a bolt shaft 6 / wiring. In Fig. 1, a dashed line is used to draw the position of the hook when pushed in or pulled out on its drawers 1, denoted by 1 '. In this 1 'position, the drawer roller 7 takes up its in or out position 7'. 50

Figure 3 shows another preferred embodiment of the drawer elements 11 according to the invention. Here, the roller track 13 is formed at the lower corner of the drawer side 12, at which the support roller 15, which is pivotally secured to the side wall 14 by a ribbed roll pin 20, rolls along and out of the drawer element 11. At the bottom of the 12 drawer pages is a. A pin 16 which carries a drawer roller 17 in a U-shaped roller wire fixed to the cabinet side 14. Of course, in both the embodiments shown in FIGS. 1 and 2 and FIG. 3, the guide rail system is formed symmetrically on both sides of the drawer plates 1 and 11, respectively.

In both exemplary embodiments disclosed herein, the base members of the drawer members 1 and 11 are made of an injectable material of suitable strength, e.g. plastic. Drawer sides 2 and 12, as mentioned, are of a profile design that also includes roller tracks 3 and 13 to which roller elements 5 and 15 mounted on the side sides 4 and 14 are connected, respectively. The design of the roller tracks 3 and 13, e.g. by means of the end position limiting path section 3a and the lifting path section 3b, it secures the drawer elements 1 and 11 to collide in the extended position and secure in the closed position. Drawer rollers 7 and 17 mounted on the lower 6 and 16 pivot shafts of the right and left drawers 2 and 12, respectively, are connected to the 8 and 18 U-shaped roller guides on the cabinet sides 4 and 14, which also prevents drawer elements 1 and 11 in a pulled out position with its tip.

Finally, it is noted that the insertion of the drawer calcinol can be accomplished in the position shown in dashed thin lines in FIG. This is the position of the drawer 1 'and the drawer roll 7'. The arrangement of the support roller 5, the roller track 3, the drawer roller 7 and the U-profile roller guide 8 allows the drawer element 1 to be tilted into the U-profile roller 8 by tilting the drawer element 1 by about 15-20 °. The drawer calcina 1 can then be pushed into place. As discussed above, the end position of drawer unit 1 is limited by the proper design of the roller track 3 on the drawer side 2.

The drawer design shown in the drawings is designed with plastic injection molding technology and is recommended for office furniture. Of course, the wardrobe was only an example, the drawer elements can be used in the same way for desk or other drawer furniture.

In the drawer design of the present invention, the advantageous inertial design of the side walls 2 and 12 provides the drawer bracket with high load capacity.

Of course, unlike the exemplary embodiments described herein, the invention may be practiced in a number of ways within the scope of the claims. For example, the choice of material is left entirely to the designer or technologist. The drawer elements are preferably made of hard PVC and the plastic rollers can be made of wear-resistant polyamide. However, the polyamide roller may be replaced by a metal bearing ¹ if necessary. In this case, it is secured to the stud with an external Seeger ring.
