Einfaohauazug for bottom drawers and the like

The invention relates to a single pull-out for bottom drawers and the like with an outer rail and an inner rail which engage with one another, the inner rail for receiving the drawer, So lift box or the like, preferably with a z-shaped Cross-section formed 1st.

It is known that in such single houses, between the

both rails to provide a revolving part in order to the two soles light for their mutual movement more common to mow and the pull-out length of the simple » Extract in the limited amount to increase. A solo moving part is often used as a roller-bearing carriage educated. A single single pull-out in which the outer rail and the inner rail as a result of the roles made of plastic are well guided in the longitudinal direction of the traveling carriage, generally has in There is considerable play across the rails. As a result, a smooth longitudinal displacement possibility of the soles relative to one another is supported, a too large lateral play between the soles, especially with

the inside rail that accommodates the drawers or the drawer but leads to the following for the person handling it: The impression that the parts interlock when pulling out once is improper and the drawer does not have sufficient guidance. A sideways flicker of the Drawers when pulling out is undesirable for the person handling it. It can also happen that the rails come into direct contact and rub, which leads to undesirable wear.

The object of the invention is to provide a simple excerpt for To create drawers and the like with a roller-bearing carriage running between the rails, in which while maintaining the ease of movement of the parts to be displaced relative to one another, these also work perfectly in the transverse direction and are reliably managed. With the Einfaoh pull-out of the type mentioned with a running roller bearing The invention is characterized by the fact that the rollers have projecting approaches in the axial direction have, which serve as a boundary system for the rails.

With such a design of the rollers on the traveling carriage between the rails, the rails also get in Exact and safe guidance in the transverse direction without increased friction. When handling the Drawer and the like do not work while the stove is being pulled out With the single pull-out, the drawer remains positively guided in the sideways direction. Slag movements cannot develop. The Rinfach pull-out offers solid leadership in all directions.

According to a further feature of the invention it is provided that the end face of the roller limiting attachment is arched is trained. Such a design of the roller approach is not only a play-free and easy guide,

achieved in particular the inner rail on the traveling carriage, but the friction conditions are extremely reduced. Since only the apex of the bulge comes into contact with the rail, this results in a one-point friction 5 between the roll or roll approach and past this

; sliding rail. In spite of safe forced guidance remains the ease of movement of the Einfaoh pull-out in the highest degree preserved.

! By the follower, roller-bearing car, it is further enables \ 10, that the outer rail can be maintained shorter than the Innensohiene without lost of extension length.

ί The invention is explained below using an> exemplary embodiment shown in the drawing.

j FIG. 1 shows a single pull-out according to the invention in a view and in a diagram.

ί Figure 2 shows a cross-section through the single extract of the j Figure 1 on a larger scale.

The single pull-out for drawers and the like has an outer rail 1 and an inner rail 2, between which rails a traveling carriage 3 is provided. This concurrent Carriage 3 has two rollers 4 at its ends and one roller in the middle of and above the rollers 4, the |

traveling carriage 3 is designed as a roller cage. The traveling carriage is advantageously made of plastic. The inner rail 2 is Z-shaped in cross section. The free leg 2 a is used to hold the bottom drawer 6 or one Drawer in a suitable manner. 7 with a Ansohlagstift is designated. The roles of the traveling carriage are in particular on the free side in alignment with protruding lugs 4 a or 5 a, which protrude so far that the inner rail 2 comes to rest. The approaches of the rollers advantageously have a curved end face 4b, 5b

on, by which sioh results in a one-point friction. the The width of the rolls with the approaches is designed so that the inner rail does not interfere with the outer rail Contact can come. The inner rail is due to the curvature of the base of the rollers and is kept at a sufficient distance from the outer rail, which has a C-shaped cross-section. Man In this way, the inner rail is guided with little friction compared to the outer rail. Auoh on the Outside of the traveling carriage 3, the rollers be provided with a preceding approach 4 o or 5 c, that comes into contact with the inner surface of the outer rail, Auoh these small protruding lugs can be a naoh have a curved contour on the outside.

As FIG. 1 shows, the outer rail 1 is kept much shorter than the inner rail. This allows the presence of the traveling Rollemmgens and the described safe guidance between the soles and the roller carriage.
