Definitions

  • the invention relates to a telescopic rail with the features specified in the preamble of claim 1 and claim 7.
  • this telescopic rail known from DE-PS 23 07 041
  • the two pairs of rails are arranged at a distance from one another and connected to one another by a Z-shaped profiled sheet in cross section, the upstanding leg of which rests on one partial rail of the inner rail and the downwardly projecting leg the other sub-rail of the inner rail is firmly attached and in the web connecting these two legs a roller with an approximately horizontal axis is mounted in a recess arranged in the middle of the profiled sheet, the running surface of which is on the underside of the upper outer rail and at the same time on the upper side of the lower outer rail rolls and thereby synchronizes their movement.
  • the advantages of this telescopic rail are associated with disadvantages in certain applications.
  • the known rail is very narrow and therefore only requires a small installation width.
  • this advantage is paid for by the large installation height of the telescopic rail.
  • the Z-shaped profiled sheet of the known telescopic rail enables to a certain extent a compensation of lateral installation dimension tolerances, which are a problem in particular in the case of wooden furniture, by the two pairs of rails around the Web of the profile sheet can be deflected a little elastically.
  • the associated loss of inherent rigidity of the telescopic rail can have a disadvantageous effect in applications in which the telescopic rail is exposed to high weight loads; this case occurs more often with steel furniture, which is usually quite accurate, so that the tolerance-compensating effect of the Z-shaped profile sheet can be dispensed with.
  • a three-part telescopic rail is known, in which the inner rail consists of four sub-rails, which are connected in pairs back to back with the interposition of a connecting plate, namely the two pairs are spaced one above the other.
  • Each of the inner part rails carries an outer part rail with ball bearings, and two outer part rails lying on a common side of the middle connecting plate are connected to one another by an outer connecting plate to form a uniform outer rail.
  • a gap is provided in the space between the upper and lower pair of partial rails of the inner rail in the middle connecting plate and a roller is mounted therein with a vertical axis of rotation, the lateral surface of which simultaneously rolls on the inside of the two outer connecting plates .
  • This telescopic rail is ge for high weight suitable, but it is complex to set up and has both a large installation height and installation width.
  • the invention solves this problem by a telescopic rail with the features specified in claim 1 and in claim 7.
  • a tension member is understood to mean an object that is to be pulled out and pushed in on telescopic rails, especially drawers in furniture, kitchens, archives and the like.
  • the telescopic rail with its one outer rail is immovably attached to the side wall of a closet, desk or other piece of furniture (also commonly referred to as a cabinet) in which the tension member is to be accommodated; the second outer rail is then attached to the side of the tension member.
  • a running rail is understood to mean any sufficiently rigid structure which has a flat surface on which the role of the telescopic rail can roll.
  • the track is on the other Adjusted tension member, which is to be attached to the telescopic rail.
  • the telescopic rail is stiffer in itself than is possible when the partial rails are arranged one above the other and at the same time their installation height is reduced.
  • the invention solves this problem elegantly in that it can roll the roll directly on one outer rail - preferably on its upper side - as before, and in that the connection required to synchronize the two outer rails to the other, second outer rail indirectly via a separate running rail takes place on which the roll also rolls and which is coupled to the tension member, which in turn is coupled to the second outer rail.
  • the invention avoids a complex construction, as is known from US Pat. No. 3,679,275.
  • the roll is easy and convenient to assemble and easily accessible at all times.
  • the object of claim 2 has the advantage that the roller is protected in the step-shaped heel, but is nevertheless arranged in a very accessible manner.
  • the Rdle preferably and in a manner known per se has a rubber-elastic tread and the rails on which the roller rolls have a roughened surface, for example a corrugated surface.
  • the contact with the running rail, which is coupled to the second outer rail, can be made in that this running rail rests under the weight of the tension member or in other ways under pressure on the roller, for which purpose this preferably projects beyond the second running rail arranged to the side, and although preferably only to such a small extent that the rubber-elastic support of the roller is compressed so far (claim 3) and / or the roller can be moved so far against spring force (claim 4) that the running rail is still on the second outer rail lying to the side of the roller can come to rest, on the top of the second outer rail, while the roller rests on the top of the first outer rail (claim 20).
  • the two inner part rails are attached to the two sides of a Z-shaped sheet metal strip, because the Z-shape increases the stability of the telescopic rail (claim 5), the two legs of the Z-shaped sheet metal strip neither in height nor laterally over the Area of the outer rails should protrude so as not to increase the installation height and width of the telescopic rail (claim 6).
  • the roller is arranged in a recess - preferably in the middle - of one of the legs of the profiled sheet metal strip and is thereby additionally protected.
  • the outer rails and the two pairs of ball troughs of the inner rail are not arranged next to one another but in one another, the ball troughs of the inner and outer rails all being arranged one above the other, preferably lying in the same vertical plane. In this way, it is reduced compared to the rail known from DE-PS 2 307 041 the installation height without significantly increasing the installation width.
  • This new telescopic rail is very compact and has high inherent rigidity.
  • the invention also solves this problem elegantly in the second solution variant in that it rolls the roll directly on one outer rail - preferably on its upper side - as before, and in that the connection required to synchronize the two outer rails to the other second outer rail is indirect via a separate running rail, on which the roller also rolls and which is coupled to the tension member, which in turn is coupled to the second outer rail.
  • the invention avoids a complex construction, as is known from US Pat. No. 3,679,275.
  • the roll is easy and convenient to assemble and easily accessible at all times.
  • Claim 8 describes the preferred orientation of the ball channels of the inner rail.
  • the structure of the rail becomes particularly easy.
  • the first outer rail has ball channels which face one another with their concave sides, while the second outer rail has ball channels whose concave sides point in opposite directions.
  • the first outer rail overlaps the inner rail and the second, lower outer rail lies with its ball troughs inside the inner rail, so it is encompassed by it.
  • the inner rail can consist of two rigidly connected partial rails, the webs connecting the ball grooves of which are arranged either next to one another (claims 9 and 10) or one above the other (claims 11 to 13).
  • the telescopic rail according to claim 14 is particularly preferred, the inner rail of which can be produced in one piece from correspondingly shaped profile material.
  • the distance between the ball troughs of the inner rail is chosen to be as small as possible (claim 15), preferably such that the ball troughs rest against one another in pairs (claim 16).
  • the running rail adapted to the tension member can be a two-leg angle rail, which is fastened with one leg to the side part of the tension member, while the other leg protrudes laterally in the manner of a support flange and the reindeer rests (claim 22).
  • the track can also be an integral part of the tension member;
  • a drawer integrally formed from plastic can be formed on both sides with a laterally protruding support flange which rests on the roller (claim 21).
  • the tension member is rigidly attached to the running rail and this is placed with its laterally projecting support flange on the roller and the second outer rail and secured against displacement on the latter, e.g. by known quick-release fasteners, which prevent sliding and lifting of the running rail from the outer rail, but also allow a certain amount of lateral play (claim 23).
  • the telescopic rail shown in Figures 1 to 3 consists of a composite inner rail 2 and two outer rails 1 and 3.
  • the inner rail 2 consists of an elongated, cross-sectionally Z-shaped profiled sheet metal strip 20, on the web on each side of a partial rail 24, 25, with their backs face each other, are fastened, preferably welded on, and in fact the two partial rails 24 and 25 are not arranged at the same height, but offset by a distance. The offset is slightly smaller than the diameter the roller 4.
  • the part rails 24 and 25 consist in a known manner of a metal profile strip with a flat web and projecting ball grooves 26, the concave sides of which are arranged pointing upwards and downwards from one another.
  • Each of the inner part rails 24 and 25 carries one of the outer rails 1 and 3, which also each consist of a metal profile strip with a flat web and adjoining ball grooves 27; the spherical grooves 27 face each other with their concave sides and the spherical grooves 26 of the partial rail 24 or 25 which surround them.
  • balls 28, which are held in a ball cage (not shown), cause the outer rails 1 and 3 to be supported and guided on the inner rail 2 precisely and easily.
  • a roll 4 is provided with a horizontal axis of rotation 10, the axis of rotation 10 of which is immovably mounted on the web 21 of the profiled sheet strip 20.
  • the roller 4 has a jacket (running surface) made of rubber and lies with slight pressure directly on the top of the first (lower) outer rail 3.
  • the drawer 5 is formed in one piece from plastic and its shape is adapted to the telescopic rail, namely it has a recess 11 in its side wall in which it receives the second, upper outer rail 1 with play.
  • the upper end of the recess 11 is formed by a support flange 6 which rests on the top of the roller 4 and serves as a running rail for the roller 4.
  • the drawer 5 is connected to the upper, second outer rail 1, e.g. by screwing or by snapping onto the outer rail 1 or by quick-release fasteners; it is sufficient that the drawer 5 is secured against sliding on the outer rail 1 in the pulling direction 12.
  • the support flange 6 When the drawer 5 is not loaded, the support flange 6 is at a short distance from the top of the upper outer rail 1. When the drawer is loaded, the rubber jacket of the roller 4 can be compressed until the support flange 6 rests on the top of the outer rail 1, as a result of which the load on the roller 4 remains limited.
  • the lower (first) outer rail 3 is to be attached to the side wall of a cabinet, not shown, in which the drawer 5 is accommodated shall be.
  • the lower outer rail 3 is therefore the immovable member of the telescopic rail.
  • FIG. 4 differs from the previous embodiment in that the drawer 5 'is designed differently and is not suitable for direct support on the telescopic rail. Rather, this is done by means of a cross-sectionally Z-shaped angle rail 13, which is laterally attached to the drawer 5 ', abuts there with its web 14 and engages with its lower leg 15 in a groove 16 in the drawer bottom which is open to the side, while the upper leg 7 of the angle rail 13 protrudes laterally in the manner of a support flange and rests on the roller 4 and the top of the upper outer rail 1 and is secured there against displacement in the direction of pull.
  • a cross-sectionally Z-shaped angle rail 13 which is laterally attached to the drawer 5 ', abuts there with its web 14 and engages with its lower leg 15 in a groove 16 in the drawer bottom which is open to the side, while the upper leg 7 of the angle rail 13 protrudes laterally in the manner of a support flange and rests on the roller 4 and the top of the upper outer rail 1 and
  • FIG. 5 differs from the first embodiment in that a sheet metal drawer 5 "is provided as a drawer, which has a welded-on simple angle rail 17 on its iw flat side surface to form a laterally projecting support flange 8 which is on the roller 4 and the top of the upper outer rail 1 rests and is secured there against displacement in the direction of pull.
  • a sheet metal drawer 5 is provided as a drawer, which has a welded-on simple angle rail 17 on its iw flat side surface to form a laterally projecting support flange 8 which is on the roller 4 and the top of the upper outer rail 1 rests and is secured there against displacement in the direction of pull.
  • the telescopic rail shown in FIGS. 6 and 7 differs from the one described above in that the three members of the telescopic rail are not arranged next to one another but in one another.
  • the inner rail 2a consists of a flat web 41, which connects two facing, central ball grooves 35 and 36, which continue up and down into an upper ball groove 31 and a lower ball groove 32, which face in opposite directions.
  • the first outer rail 3a runs on balls 28, which consists of a flat web 39 and two mutually facing ball grooves 31 and 32, which receive the inner rail 2a between them.
  • the second, lower outer rail 1a runs on balls 28, which consists of a flat web 40 and two ball grooves 37 and 38 facing in opposite directions and facing the middle ball grooves 35 and 36.
  • the inner rail 2a and the two outer rails 1a and 3a are formed in one piece from profile material.
  • the two webs 39 and 40 of the outer rails 1a and 3a lie on the two outer sides of the telescopic rail.
  • the web 39 of the first outer rail 3a is fastened to a cabinet wall (not shown), while the web 40 of the second outer rail 1a bears against the side of a drawer 5a or the like tension member.
  • the drawer 5a is secured in the usual way against displacement in the direction of pull 12 relative to the second outer rail 1a.
  • an arm 42 e.g. a sheet metal strip attached, which protrudes vertically upwards and carries with the horizontal axis of rotation 10 a roller 4 which on the top of the first outer rail 3a, i.e. on the outside of the ball groove 31, rolls.
  • a roller 4 which on the top of the first outer rail 3a, i.e. on the outside of the ball groove 31, rolls.
  • a support flange 6a e.g. angle rails are also used, as shown in FIGS. 4 and 5.
