Definitions

  • the present invention relates to a drawer pull-out guide comprising at least one guide rail.
  • the guide rail includes a longitudinally extending first limb and at least one longitudinally extending second limb angled from the first limb, and the first limb and the second limb are connected to one another along their longitudinal direction by an angled region.
  • the invention concerns a drawer pull-out guide comprising at least one guide rail of the type to be described, and a method for producing a guide rail for a drawer pull-out guide.
  • Such guide rails are used for drawer pull-out guides, so that a drawer can be supported so as to be extendable relative to a furniture carcass in a mounted position.
  • the drawer pull-out guides usually include a first guide rail configured to be fixed to a furniture carcass, and at least one second guide rail configured to be displaceable relative to the first guide rail.
  • a displaceably supported third guide rail may be arranged.
  • rolling bodies are provided, the rolling bodies being supported in a running carriage or also in a plurality of displaceable running carriages.
  • the angled region includes at least one material diminution extending along the angled region and formed by a recess.
  • At least one material diminution, formed by a recess, having a reduced material thickness is provided in an angled region enclosed by the two limbs of the guide rail (that is to say, on an inner side or on an inner radius of the angled region between the two limbs).
  • the two limbs are angled to one another about a notional axis extending in a longitudinal direction of the recess.
  • the limbs can be angled to one another to a larger extent, for example in such a way that the two limbs adopt not only an angle of 90°, but also an angle of 180° relative to one another.
  • the angled region can be configured so as to be more sharp-edged, and the guide rail can be produced with a more compact design.
  • a particular advantage of the invention lies in the fact that by the proposed measure, the flat running surfaces of the guide rails provided for the contact with the rolling bodies can be enlarged. Therefore, while maintaining the size of the guide rail, wider rolling bodies can be utilized and, as a result, the occurring forces can be distributed over a larger area. In this way, the stability and the loading capacity of the drawer pull-out guide can be additionally improved.
  • first limb and/or the second limb has or have a predetermined first material thickness
  • the material diminution formed by the recess of the angled region has a reduced second material thickness in relation to the first material thickness.
  • first material thickness relates to the thickness of the raw material of the guide rail, without considering possible embossments or bends of the guide rail.
  • the at least one recess can extend at least over a region, preferably over substantially an entire length of the guide rail, in the longitudinal direction of the guide rail. Thereby, the recess is configured as a groove.
  • the first limb and the second limb in a region outside the recess, bear against one another at least over a region. This is, in particular, the case when the two limbs are angled relative to one another by 180°.
  • the drawer pull-out guide according to the invention is characterized by at least one guide rail of the described type.
  • the drawer pull-out guide includes a first guide rail configured to be fixed to a furniture carcass, and at least one second guide rail displaceably supported relative to the first guide rail.
  • At least one rolling body is arranged between the first guide rail and the second guide rail, and the at least one rolling body is configured to run along the first limb or on the second limb of a guide rail.
  • FIG. 1 is a perspective view of an item of furniture comprising a furniture carcass and drawers displaceably supported relative thereto,
  • FIG. 2 a , 2 b show the drawer pull-out guide in an exploded view and in a cross-sectional view
  • FIG. 3 a , 3 b show a comparison between a guide rail according to the prior art and a guide rail according to the invention
  • FIG. 4 a , 4 b show a flat material strand with inserted recesses and the guide rail as a finished product.
  • FIG. 1 shows an item of furniture 1 having a cupboard-shaped furniture carcass 2 , and drawers 3 are displaceably supported relative to the furniture carcass 2 by drawer pull-out guides 4 .
  • Each of the drawers 3 includes a front panel 5 , a drawer bottom 6 , drawer sidewalls 7 and a rear wall 8 .
  • Each of the drawer pull-out guides 4 includes a first guide rail 9 (carcass rail) configured to be fixed to the furniture carcass 2 by fastening portions 12 a, 12 b, and a third guide rail 11 (drawer rail) displaceably supported relative to the first guide rail 9 , the third guide rail 11 being connected or being configured to be connected to the drawer sidewall 7 .
  • a second guide rail 10 central rail
  • the second rail 10 being displaceably supported between the first guide rail 9 and the third guide rail 11 so as to allow the drawer 3 to be fully extended.
  • FIG. 2 a shows an exploded view of the drawer pull-out guide 4 with the first guide rail 9 (carcass rail) to be fixed to the furniture carcass 2 , the third guide rail 11 (drawer rail) to be connected to the drawer 3 , and with the second guide rail 10 (central rail) displaceably supported between the first guide rail 9 and the third guide rail 11 .
  • the first guide rail 9 includes two fastening portions 12 a, 12 b spaced from each other in the longitudinal direction (L), the first guide rail 9 being configured to be mounted to the furniture carcass 2 by the fastening portions 12 a, 12 b.
  • At least one first running carriage 13 having a plurality of rolling bodies 14 , 15 is displaceably supported between the first guide rail 9 and the second guide rail 10 .
  • the rolling bodies 14 are spaced from each other in the longitudinal direction (L), and each of the rolling bodies 14 has a rotational axis extending horizontally in the mounted position. On the contrary, each of the rolling bodies 15 has a vertically extending rotational axis in the mounted position.
  • a spring-assisted retraction device 16 By a spring-assisted retraction device 16 , the third guide rail 11 can be retracted into the closed end position at the end of the closing movement, and the spring-assisted closing movement can be decelerated by a damping device 17 , for example in the form of a hydraulic piston-cylinder-unit.
  • FIG. 2 b shows the drawer pull-out guide 4 in a cross-sectional view, in which the first running carriage 13 with the rolling bodies 14 , 15 is supported between the first guide rail 9 and the second guide rail 10 .
  • At least one second running carriage 18 having rolling bodies 14 a, 15 a is displaceably supported between the second guide rail 10 and the third guide rail 11 .
  • Each of the rolling bodies 14 a has a rotational axis extending horizontally in the mounted position, whereas the rolling bodies 15 a are configured to be rotated about a vertically extending rotational axis in the mounted position.
  • the second guide rail 10 includes a first limb 10 a and at least one second limb 10 b, the first limb 10 a and the second limb 10 b being connected to one another by an angled region 23 .
  • the angled region 23 includes a material diminution formed by a recess 21 extending along the angled region 23 .
  • Each of the first limb 10 a and/or the second limb 10 b can have a predetermined first material thickness, whereas the angled region 23 enclosed by the two limbs 10 a, 10 b is provided with at least one recess 21 , so that the angled region 23 has a reduced second material thickness in relation to the limbs 10 a, 10 b.
  • the limbs 10 a, 10 b due to the presence of the recess 21 , can be angled to one another to a larger extent, without substantial compressive stress occurring on the inside of the angled region 23 when the second guide rail 10 is machined.
  • the limbs 10 a, 10 b are angled to one another by 180°.
  • the two limbs 10 a, 10 b at least partially bear against one another, preferably without the formation of a gap 19 ( FIG. 3 a ).
  • the guide rail 10 can also include two or more material diminutions formed by recesses 21 , 21 a, 21 b.
  • the limbs arranged adjacent to the recesses 21 a, 21 b each adopt an angle of approximately 90° to one another.
  • FIG. 3 a and FIG. 3 b show a direct comparison between a guide rail 10 according to the prior art ( FIG. 3 a ) and a guide rail 10 according to the invention ( FIG. 3 b ).
  • the guide rail 10 according to the prior art depicted in FIG. 3 a has a constant material thickness M 1 , and the limbs 10 a, 10 b —due to the lacking recess 21 —are spaced from each other in a height direction under the formation of a gap 19 . This also leads to an increase in the height (H) of the guide rail 10 .
  • the angled region 23 has round-shaped configuration.
  • only running surfaces B, C having a relatively small width are available for the rolling bodies 14 , 15 , 14 a, 15 a.
  • FIG. 3 b shows an embodiment of the guide rail 10 according to the invention. Due to the recesses 21 , 21 a, 21 b, the material thickness M 2 is reduced in comparison to the material thickness M 1 , so that the limbs 10 a, 10 b can be angled to one another to a stronger extent. This leads to the fact that the height H 1 according to FIG. 3 b is smaller than the height H according to FIG. 3 a . The smaller height H 1 thus leads to a (desired) reduced constructional height of the guide rail 10 . Moreover, it is visible that the flat running surfaces B 1 , C 1 for the rolling bodies 14 , 15 , 14 a, 15 a, in comparison with the flat surfaces B, C according to FIG.
  • the recesses 21 , 21 a, 21 b, in a cross-section perpendicular to the longitudinal direction (L), can each include at least one concave portion 22 .
  • the sharp-edged angled regions 23 can be preferably produced by a roll forming operation.
  • Roll forming also known as roll profiling or cold rolling is a continuous bending method in which a material strand 20 ( FIG. 4 a ) of metal runs into a profiling machine, and the material strand 20 is reshaped in the profiling machine by numerous subsequent bending operations until the desired shape of cross-section is produced.
  • the at least one guide rail 10 in a mounted position of the drawer pull-out guide 4 , includes a substantially vertically extending portion 24 , and the first limb 10 a protrudes transversely, preferably at a right angle, in a first direction from the vertically extending portion 24 of the guide rail 10 .
  • the second limb 10 b protrudes transversely, preferably substantially at a right angle, from the vertically extending portion 24 in a second direction, opposing the first direction.
  • the first limb 10 a and the second limb 10 b of the at least one guide rail 10 are configured so as to have a different length. It can be preferably provided that the second limb 10 b has a length being at least three times as long as a length of the first limb 10 a.
  • FIG. 4 a shows a longitudinally extending material strand 20 , in which recesses 21 , 21 a, 21 b are introduced in a first step, preferably by roll forming. Subsequently, the material strand 20 is deformed or bent in a region of the recesses 21 , 21 a, 21 b, whereby at least one first limb 10 a and at least one second limb 10 b are formed, and the recesses 21 , 21 a, 21 b are arranged in an angled region 23 enclosed by the first limb 10 a and by the second limb 10 b.
  • each angled region 23 can also include two or more recesses 21 , 21 a, 21 b.
  • the guide rail 10 can include a third limb 10 c and a fourth limb 10 d which are connected to one another by a second angled region 23 a.
  • the second angled region 23 a can have a second material diminution formed by a second recess 21 b.
  • the guide rail 10 can have a fifth limb 10 e and a sixth limb 10 f which are connected to one another by a third angled region 23 b.
  • the third angled region 23 b can have a third material diminution formed by a third recess 21 a.
  • the limbs 10 a, 10 b, 10 c, 10 d, 10 e, 10 f arranged adjacent to one another can each be angled to one another by an angle of approximately 45°, 90° or 180°.
