  • the solution according to the invention has the particular advantage that the container is connected to the telescopic rails by means of a single locking process, so that the locking and unlocking process is considerably simplified. In addition, any cleaning of the container which may be necessary is not made more difficult by locking elements or locking aids arranged thereon.
  • the molded parts are particularly easy and simple to assemble without additional fastening means if, according to a preferred embodiment of the object of the invention, it is provided that they are held on the telescopic rails by a plug connection.
  • the molded parts are inserted into the interior space formed by the profile of the telescopic rails and held therein by means provided on the telescopic rails and on the molded parts.
  • the means are formed from positively interacting stops and counter-stops as well as from retaining lugs and tabs.
  • the molded parts are held particularly securely and precisely in relation to the forces occurring when the container is moved.
  • the retaining lugs are arranged like barbs on the legs of the shaped parts, which essentially have a trapezoidal contour, and hook with rags protruding from the raceways when the shaped parts are inserted into the telescopic rails.

  • the hook-like receptacles are provided with a bevel forming their back, which serves as a skid for the pin on the molded part when the container is locked with the telescopic rails.
  • This solution is characterized, on the one hand, by a uniform, low-wear latching action due to the bevel. On the other hand, locking is made considerably easier due to the guiding function of the slopes.
  • the container and the telescopic rails are connected to one another particularly securely and reliably if, according to a further advantageous embodiment of the object of the invention, it is provided that the trapezoidal shaped parts are equipped at their base with a resilient element which supports the locking state between the container and the telescopic rails Support on the container inserted in the telescopic rails.
  • the resilient element is designed as a leaf-spring-like tongue, the root of which is arranged at the base of the trapezoid and the free end of which is spaced apart therefrom.
  • the free end of the leaf spring-like tongue is pretensioned at approximately the height of the pin on the front wall of the container, whereby the hook-like receptacle on the container as a result of the spring force exerted by the tongue the pin is locked.
  • the trapezoidal shaped part on its side opposite the base has a curvature directed towards the base, which serves as a limitation for the insertion depth when the telescopic rails are pushed together.
  • This measure means that a separate part serving as a depth stop is superfluous, as a result of which the mounting of the containers on the telescopic rails is additionally simplified.
  • the container from the telescopic rails in their collapsed state and can be unlocked by lifting by overcoming the spring force applied by the leaf spring-like tongues of the molded parts.
  • This solution is characterized by the fact that the container can be removed from the telescopic rails in one-hand operation without additional unlocking operations to be carried out simultaneously.
  • a drawer-like container 10 which is intended for storing refrigerated goods in a household refrigerator or freezer and not shown for its better accessibility in the interior formed by its refrigerated goods container on telescopic rails 11 is pulled out.
  • the container 10 which essentially presents itself as a flat tub 12, is equipped on the front side with a handle 13 serving as a handle and facilitating its operation, the free end of which allows access to the bottom of the tub.
  • the container 10 On both sides of its side walls running in the guiding direction, the container 10 has, in the plane of its opening, support strips 14 which are directed away from the latter and are designed as angled portions and which extend over the telescopic rails 11 to be attached to the side walls of the interior and face the bottom 12 of the tub Support the page on its surface.
  • the telescopic rails 11 are designed as so-called differential telescopic rails, which have a fixed part 15 to be fastened to the side walls of the interior and a movable part 16 assigned to the side walls in the guide direction of the container 10 and an intermediate part movably guided between rollers 17 and 17 ' 18 have.
  • the movable parts 16 of the telescopic rails 11 are provided on their side facing the handle 13 with recesses 19 cut out from their opposite raceways for the rollers 17, which recesses essentially form a molded part 20
  • Trapezoidal contour belonging retaining lugs 21 cooperate and which are arranged on the legs 22 of the isosceles trapezoid.
  • 16 retaining lugs can be provided on the raceways of the parts, which in Intervene bulges on the molded part 20.
  • holding measures for the molded part 20 on the web of the parts 16 between their raceways are also conceivable.
  • its legs 22 face the raceways of the part 16, the legs 22 starting from the base of the trapezoid tapering towards one another and serving as an insertion aid for the molded part 20 into the profile of the part 16.
  • the molded part 20 is positively fixed in the part 16 in the direction of the handle 13 of the container 10.
  • the molded part 20 is positively secured by the interaction of a shoulder 23, which is arranged on the leg 22 of the trapezoid and near its base and serves as a stop, with a counter stop 24, the end face of the part 16 facing the shoulder 23 being used as the counter stop 24 the telescopic rail 11 is used.
  • a leaf spring-like tongue 25 which is designed as a spring and is identical with the material thickness of the shaped part 20, is arranged, the root 26 of which lies at the base of the trapezoid in the direction of the leg 22 lying lower in the installed position of the shaped part 20.
  • the tongue 25 has two sections of different lengths, of which the longer section associated with the root 26 is bent away from the base, while the shorter section immediately adjacent to the longer section runs parallel to the base, the resulting distance from the Base serves as spring travel for the tongue 25.
  • the shorter, stub-like section ends set back to the top edge of the base.
  • the molded part 20 On its side opposite the base, the molded part 20 has a curvature 27 which extends over the distance between the two legs 22 and which is directed toward the base and is averaged with respect to the distance between the two legs 22. Between the base and the curvature 27, more facing the base of the trapezoidal shaped part 20, lying close to the higher leg 22, there is a pin 28 of circular cross section, which is perpendicular to the surface of the shaped part 20 facing it and is connected to it.
  • the pin 28 is one of the two elements which bring about the releasable connection between the part 16 of the telescopic rails 11 and the container 10, the pin 28 of the molded part 20 for producing the connection between the container 10 and the movable part 16 being shaped like a hook, recess 30 arranged within a triangular stiffening element 29 engages.
  • the stiffening element 29 is formed as an edge angled downward on both sides of the container 10 from the support strips 14, which is connected to stabilize the container 10 with the front wall of the container 10 assigned to the handle 13, the hypothenus of the triangle between the front wall and the Support strips 14 runs.
  • the hook-like receptacle 30 is molded into the stiffening element 29 in such a way that its hook part 31 runs essentially parallel to the support strips 14. Above its hook part 31, the hook-like receptacle 30 has a semicircular, the diameter of the pin 28 substantially adapted, the second element of the releasable connection forming receiving part 32, within which the pin 28 is in the locked state and which is towards the front wall of the corresponding clearance 33 is provided.
  • the hook-like receptacle 39 on its side opposite the recess 33 has a slope 34 forming the back of the receptacle 30, which represents a section of the hypotenuse and serves as a sliding skid for the pin 28 on the molded part 20 when the container 10 is locked in place with the telescopic rails 11 .
  • the tongue 25 is supported with its shorter section against the side of the front wall facing it under pretension of the leaf spring-like tongue 25 at approximately the height of the pin 28, as a result of which the receiving part 32 the hook-like receptacle 30 is locked with the pin 28 as a result of the spring force exerted by the tongue 25.
  • the container 10 is on the one hand positively secured against lifting from the movable parts 16 of the telescopic rails 11 and on the other hand also connected to them in a positive manner in its pull-out direction predetermined by the telescopic rails 11. If the automatic latching process between the receiving part 32 and the pin 28 is prevented, for example by increased friction between the support strips 14 and the parts 16, the latching process takes place the next time the container 10 resting on the telescopic rails 11 is pulled out.
  • the unlocking process of the container 10 with respect to the movable parts 16 of the telescopic rails 11 is initiated by overcoming the spring force of the tongue 25, the telescopic rails 11 for this purpose shortest length that rails 11 for this purpose to their shortest length, which is determined by the stop of the curvature 27 on the running surface of the roller 17 assigned to it, moved together.
  • the correct unlocking position is signaled by striking the pin 28 on the stop surface 35 opposite the receiving part 32 and belonging to the stiffening part 29 and running almost parallel to its catheter connected to the front wall. In this position, the container can be removed from the telescopic rails 11 in accordance with the arrow pointing upward.
  • the bevels 34 of the hook-like receptacles 30 arranged on both sides of the container 10 are placed on the pins 28. Subsequently, the container 10 is acted upon by a force acting in its insertion direction, whereby the bevel 34 slides along on the pin 32 until it passes after leaving the hook part 31 into the area of the receiving part 32 and there on a parallel to the support strips 14th stops and stop side 36 belonging to the hook-like receptacle 30.
  • the molded part 20 is produced in one piece from plastic injection molding, but a multi-part production method, for example in the form of a tongue 25 designed as an insert, which is made from flat spring steel, would also be conceivable. It could also be the tongue 25 can also be designed as a replacement part, in which case the molded part 20 should have an insertion groove which holds the tongue in the manner of a beam clamped on one side. In particular, in the case of the last-mentioned embodiment possibility, it would be possible without difficulty to adapt the force to be exerted by the leaf spring-like tongue 25 in accordance with the requirements for the locking between the container 10 and the telescopic rails 11.
  • the tongue 25 could be arranged with its root 26 on the higher leg 22, in which case the free end of the tongue 25 would be assigned to the lower leg 22 and spaced from the base of the trapezoid.
  • the tongue 25 would serve as a skid for the front wall assigned to the handle 13 of the container, whereby the locking process would be further facilitated and favored.
