Definitions

  • the invention relates to a support part for intermediate shelves that can be inserted into the interior of a piece of furniture, for support at the edges thereof, in particular Fastening elements of the supporting parts can be inserted snugly on their walls.
  • DE-OS 38 02 140 discloses a support element for supporting and carrying shelves arranged in the interior of a cooling device, which is held on the side walls of a refrigerated goods container forming the interior.
  • the support element on its side opposite its supporting section is equipped with horizontally spaced plug pins that are axially slotted and form expansion pins that can be frictionally inserted into adapted bores on the side walls of the interior formed by the refrigerated goods container.
  • the frictional connection between the bores and the plug pin is achieved by an outer diameter of the plug pin which is larger than the inside diameter of the plug pin and which, because of its slotted design, is elastically deformable transversely to its longitudinal axis when driven into the hole and counteracts in the hole its spread position is elastically deformed pin segments, which exert a pressing force on the bore wall.
  • the pressure force generated by the elasticity of the pin segments formed by the slitting of the pin is essentially a function of the geometric shape of their cross-sectional area and the dimensions of this cross-sectional area.
  • the invention has for its object to design a plug pin with elastic properties such that on the one hand the pin is made in one piece and on the other hand good elasticity of the pin is achieved in a particularly simple manner.
  • the pins are designed as hollow pins, the walls of which delimit the cavity in the axial direction of the pin are provided with mutually opposite indentations which reduce the thickness of the wall.
  • the pin according to the invention Due to the construction of the pin according to the invention with a closed outer surface, its outer diameter can be manufactured within narrow tolerance limits, so that the insertion force for the pin in the receptacles provided for this purpose is kept within defined limits and consequently an almost constant clamping effect for the pin in the receptacles is ensured .
  • the elasticity of the pin can be influenced in a simple manner by the depth and the cross section of the indentations.
  • the indentations reduce the walls to a film hinge-like thickness and are designed as longitudinal grooves running in the axial direction of the hollow pin over its length.
  • the longitudinal grooves in the walls are introduced into the walls from the side of the cavity.
  • This solution is characterized by a closed, smooth outer surface, due to which the insertion force is reduced without changing the holding force for the pins in the receptacles because of their reduced friction in the receptacles.
  • a pin is particularly elastically deformable if, according to a further preferred embodiment of the object of the invention, it is provided that the longitudinal grooves have a rectangular cross-section.
  • the longitudinal grooves in the pin are particularly easy to insert if, according to a further preferred embodiment of the object of the invention, it is provided that the longitudinal grooves have a semicircular cross section.
  • the walls on their lateral surfaces are provided with ribs running in the direction of the longitudinal grooves in the region of their smallest wall thickness produced by the longitudinal grooves.
  • Such a solution is characterized in that a targeted deformation of the wall thickness remaining in the region of the longitudinal grooves is achieved inward by the attachment of the ribs, so that the displaced material is not plastically but elastically deformed when the pin is deformed along its axis.
  • the deliberate action on the walls in the region of the longitudinal grooves results in a clamping effect for the pins in the receptacles as a result of an elastic deformation of these walls.
  • a full-surface perforation of the pins in the receptacles is avoided, so that more favorable insertion conditions are created for the pins in the receptacles.
  • the hollow pin has an oval cross-section which is adapted in shape and size to the cross-section of the receptacles.
  • Oval is understood here to mean a surface stretched along an axis of symmetry with boundary lines curved at the ends.
  • planar structures can be, for example, an ellipse or two semicircles facing one another or semi-ellipses with a rectangle in between.
  • the hollow pin has a round cross section which is adapted in shape and size to the cross section of the receptacles.
  • a household refrigerator 10 which has a heat-insulated housing 11, the interior of which is formed by a refrigerated goods container produced by deep-drawing a plastic board and can be closed with a door 12.
  • the interior of the housing 11 is provided for storing refrigerated goods with shelves 13 arranged at different heights, forming individual compartments, the edges of which are bordered by an edge 14.
  • the lateral sections formed as legs 15 are carried by differently shaped support parts 20 and 30, of which the support parts provided with the reference numerals 20 are arranged near the opening of the interior, while the support parts 30 are in the rear area of the interior.
  • the supporting parts 20 are equipped with a support element 21 having a substantially T-shaped cross section, the T-shaped profile of which is rotated by 90 ° with respect to its normal position, so that its usually vertically arranged leg extends horizontally.
  • the horizontally extending leg serves as a supporting surface 22 for the section of the legs 15 assigned to it, whereby these are each provided on their underside with a recess into which the supporting surfaces 22 are able to dip and are thus received by the recesses, so that the Trays 13 are held positively both in the direction of insertion into the interior and in the opposite direction.
  • the vertically arranged, as a stop wall 23 serving leg of the T-shaped support element 21 is divided by the wing 22 into two different high sections, the higher section lying above the wing 22 is provided at its lateral edges with two resilient tongues 24, the roots 25 of which on the higher section are also molded.
  • the bodies of the tongues 24 essentially have two zones, of which the longer zone assigned to the root 25 is curved away from the side of the stop wall 23 facing it and encloses an acute angle between itself and the side of the stop wall 23.
  • the second zone, which is angled toward the stop wall 23, has a larger intermediate angle with respect to a vertical running through the curvature than the first zone facing the tongue root 25.
  • the first zone of the tongues 24 serves as a kind of skid for the legs 15 when the tray 13 is arranged on the wing 22, the second zone in the case of legs 15 placed on the wings 22 applies a force to the associated outer edge of the legs 15, one of which secures the positive fit between the wings 22 and the recesses on the underside of the legs 15 in a force-locking manner.
  • a recess 26 serving as spring travel for the tongues is created, into which the tongues 24 dip when they are loaded.
  • the support parts 30 arranged in the rear region of the interior accommodate the leg sections facing them in a receptacle 31, the height of which is limited by two plates 32 and 33, which are substantially trapezoidal in plan view, of which the lower plate 32 is one of them has upstream, directed towards the opening of the interior extension 34, which is connected to the plate 33 with the same height, forming a continuous wing.
  • the extension 34 serves as a feeding aid for the leg sections in the direction of insertion into the receptacles 31.
  • the higher lying plate 32, shortened by the extension 34 is equipped on the side facing away from the extension 34 with a bead 35 which is semicircular in cross section and which is directed into the receptacle 31 and clamps the section of the leg 15 arranged therein.
  • a cuboid end wall 36 is arranged at a distance from the bead 34, the height of which, given its shorter side, corresponds to that of the receptacle 31.
  • a parallelepiped-shaped wall 37 At the base of the trapezoidal plates 32 and 33 there is also a parallelepiped-shaped wall 37, the longer sides of which are connected to the bases of the trapezoidal plates 32 and 33 and the shorter side facing away from the extension 34 is connected to the end wall 36, so that 31 a closed corner area is formed.
  • the wall 37 is equipped with a bevel 38 which is arranged above the height of the side and which laterally feeds the leg sections of the shelves 13 assigned to the receptacles 31 to the receptacles 31.
  • Both the supporting parts 20 and the supporting parts 30 are provided with an oval cross-section, serving as a fastening element, on their walls 23 and 27, with their longitudinal axis perpendicular to the walls 23 and 27, in relation to their supporting surfaces supporting the shelves 13 the longer main axis running through the oval is arranged parallel to the wings, above these.
  • the pins 40 are designed as hollow pins open at their free ends, the cavities 41 of which are delimited by walls 42 defining the contours of the pins 40, the recesses running as longitudinal grooves 43 running in the axial direction of the pin 40 exhibit.
  • the two longitudinal grooves 43 which are rectangular in cross section, are parallel to each other along the length of the pin 40, and are also a mirror image of the longer main axis of the oval, from the inside facing the cavity 41 into the wall 42, up to a wall hinge-like thickness of the wall 42 reducing depth molded into this, the cross section of the longitudinal grooves 43 is also averaged to the shorter main axis of the oval.
  • a rib 44 On the outside of the wall 42, facing the lower section of the stop wall 23, there is a rib 44, which is centered on the cross section of the longitudinal groove 43 and is set back from the free end of the pin 40 and has a triangular cross section and up to the outside facing the pin 40 the stop wall 23 extends.
  • a rib 44 can also be associated with the higher longitudinal groove 43 or with both longitudinal grooves 43 in the manner set out.
  • the supporting parts 20 and 30 can be inserted with their identically designed pin 40 into receptacles 45, which are arranged in the area of the opening and in the rear area of the interior on the side walls 46 in a vertical row, at equal distances from one another.
  • the receptacles 45 are also molded onto the side walls 46 in the form of a deep-drawn bowl with an oval cross section on the input side, the inner contour of which is adapted to the outer contour of the pin 40 in such a way that the outside of the cavity 41 facing away from the cavity Wall 42 with pins 40 inserted into the receptacles 45 essentially nestles against the cup walls.
  • the rib 44 on the underside of the pin 40 contributes to the clamping of the pin 40 in the receptacles 45, but a full-surface perforation is avoided.
  • the radius arranged on the input side on the receptacles 45 the area around the base of the pin is exposed when the pin 40 is inserted into the receptacle 45, so that due to its connection to the stop wall 23, only a little elastic part of the pin 40 is not deformed.
  • the arrangement of the rib 44 on the wall thickness of the wall 42 reduced by the longitudinal groove 43 achieves a certain elasticity for the clamping connection of the pin 40 in the receptacles 45.
  • the wall 42 of the pin 40 can be provided with a plurality of longitudinal grooves 43 lying opposite one another in pairs in order to further increase the elasticity of the pin, it being possible for ribs 44 to be associated in the area of these longitudinal grooves in the manner already described.
  • the design of the pin 40 is not only limited to oval cross-sections, but is equally suitable for other cross-sectional shapes.
  • the support parts 20 and 30 are made in one piece from plastic injection molding, but a multi-piece embodiment in a different manufacturing method would also be conceivable.
