Extension guide fitting for drawers

#The invention relates to an extension guide fitting for drawers comprising an extension rail at the drawer side, a carrier rail at the furniture body side, and a middle rail which runs between those two rails at both sides of the drawer. The load between the rails is transmitted by running rollers which are mounted in separate carriages. Mounted in the front region of the carrier rail is a stationary support roller on which the extension rail runs with a running limb and is supported at least in the closed condition of the drawer.

#In the case of guide arrangements with running rollers which are mounted in their own carriages, the load-transmitting running elements (namely, the carriages with the rolling bodies) are disposed rather in the center of the guide system. In this connection, the term running rollers is used to denote rolling bodies quite generally, that is to say disc-shaped runner wheels, balls and rollers.

#In the case of extension guide fittings with riveted running rollers, the load-transmitting elements are at the largest possible spacing from each other in the closed condition.

#Embodiments of the invention are described hereinafter with reference to the Figures of the accompanying drawings.

#FIG. 1 shows a perspective view of an extension guide fitting according to the invention,

#FIG. 2 shows an exploded perspective view of an extension guide fitting according to the invention,

#The extension guide fitting 1 according to the invention has a carrier rail 2 which is secured to a side wall of an article of furniture, an extension rail 4 which is secured to the drawer 10 and a middle rail 3 which runs between the two rails 2, 4.

#Provided between the carrier rail 2 and the middle rail 3 is a carriage 5 carrying running rollers. At least one carriage 5 with running rollers is also disposed between the middle rail 3 and the extension rail 4.

#As, in the closed condition of the drawer 10, the carriages 5 are located substantially in the middle of the guide system, instability of the drawer 10 could not be avoided in the case of a conventional extension guide fitting.
