  • bottom-mounted slides are provided between drawers and bodies of, e.g., desks, to enable users to easily open or close the drawers.
  • a stationary member is fastened to a sidewall or bottom plate of a drawer by an extension.
  • a movable member is fastened to a lower surface of a bottom plate of a desk.
  • Three raceways are formed in each of both lateral sides of an intermediate member.
  • a plurality of balls is located between the stationary member and the intermediate member and between the movable member and the intermediate member. The balls roll along the raceways. Thereby, the intermediate member slides along the stationary member, and the movable member slides along the intermediate member.
  • FIG. 1 is a sectional view showing a conventional bottom-mounted slide 10 disclosed in US Patent No. 6,132,020 .
  • the conventional bottom-mounted slide 10 includes a movable member 13, a stationary member 17 and an intermediate member 14 which is interposed between the movable member 13 and the stationary member 17.
  • the stationary member 17 is fastened to a sidewall panel 16 of a body of, for example, a desk, and the movable member 13 is fastened to the lower surface of a drawer panel 11.
  • Three raceways are formed on each of lateral sides of the intermediate member 14.
  • Balls 15 are provided between the movable member 13 and the intermediate member 14 and between the intermediate member 14 and the stationary member 17.
  • the balls 15 roll along the corresponding raceways so that the intermediate member 14 slides along the stationary member 17 and the movable member 13 slides along the intermediate member 14.
  • the slide 10 is generally operated in a three-stage folding manner.
  • the slide 100 of No. 2007-17214 includes a first member 130 which substantially supports a load.
  • Triangular raceway forming parts 133 and 133' are respectively provided on the lateral sides of the first member 130.
  • An extension 145 which is oriented in the vertical direction is provided between the triangular raceway forming parts 133 and 133'.
  • a horizontal web is longer than a lateral web.
  • the conventional slide 100 can increase the stability with respect to the rotational moment when a comparatively high load is applied thereto.
  • the conventional slide 100 is problematic in that a defective proportion of movable members produced by roll-forming increases and, in particular, there is a comparatively high proportion of defective raceway forming parts 133 and 133' formed by roll-forming.
  • an object of the present invention is to provide a bottom-mounted slide which can reduce a proportion of defectives formed by roll-forming compared to the conventional bottom-mounted slide.
  • Another object of the present invention is to provide a bottom-mounted slide in which the volume of hollow spaces formed in a movable member can be minimized, thus enhancing the strength of the slide.
  • a further object of the present invention is to provide a bottom-mounted slide in which symmetric depressed parts are provided in both lateral sides of the movable member so that the depressed parts are resistant to compression force applied to the slide, thus improving the stability of the slide.
  • a still another object of the present invention is to provide a bottom-mounted slide which can be used to support a comparatively high load.
  • the present invention provides a bottom-mounted slide, including: a movable member, with a plurality of first raceways formed in both lateral sides of the movable member; stationary members each of which has a plurality of second raceways, the second raceways being respectively connected to the first raceways by corresponding balls to guide the movable member, the balls rolling along the corresponding first and second raceways; a ball housing provided between the movable member and each of the stationary members, the ball housing supporting the balls.
  • a depressed part is provided in a predetermined portion of each of the lateral sides of the movable member between the corresponding first raceways. The depressed part is inserted into a hollow space defined inside the first raceways of the corresponding end of the movable member.
  • the depressed part may have a U shape.

  • the depressed part may be aligned with a lateral axis of the movable member.
  • the depressed part may be formed at a medial portion between the corresponding first raceways.
  • the present invention provides a method of manufacturing a movable member for a bottom-mounted slide, including: forming a depressed part in a predetermined portion of each of horizontal webs provided on both lateral sides of the movable member, the depressed part being inserted into a hollow space formed inside the corresponding horizontal web; and forming raceways in the respective lateral sides of the movable member, the raceways coming into contact with rolling balls.
  • the depressed part may have a U shape.
  • the movable member may include the horizontal web and a lateral web, the horizontal web being longer than the lateral web.
  • the forming of the depressed part may comprise aligning the depressed part with a lateral axis of the movable member.
  • the forming of the depressed part may comprise forming the depressed part at a medial portion between the corresponding raceways.
  • the proportion of defectives formed by roll-forming can be reduced, compared to the conventional bottom-mounted slide.
  • the volume of hollow spaces formed in a movable member can be minimized, thus enhancing the strength of the slide.
  • symmetric depressed parts are provided in both lateral sides of the movable member so that the depressed parts are resistant to compression force applied to the slide, thus improving the stability of the slide.
  • the bottom-mounted slide can be used to support a comparatively high load.
  • FIG. 3 is a sectional view of the bottom-mounted slide 30, according to the embodiment of the present invention.
  • FIG. 4 is a perspective view showing a movable member 35 of the bottom-mounted slide 30 according to the present invention.
  • the bottom-mounted slide 30 includes a movable member 35, stationary members 32 and reception members 34.
  • a plurality of first raceways 37 is formed on each of both lateral sides of the movable member 35.
  • Each stationary member 32 has a plurality of second raceways 33 which are respectively connected to the first raceways 37 by corresponding balls 39 to guide the movable member 35.
  • the balls 39 roll between the corresponding first and second raceways 37 and 33.
  • Each ball housing 34 is provided between the movable member 35 and the corresponding stationary member 32 and houses the balls 39 therein.
  • a ball retainer which has a width greater than that of the conventional ball retainer 4 is used as the ball housing 34.
  • a U-shaped depressed part 40 is provided in a predetermined portion of each end of the movable member 35 between the corresponding first raceways 37 such that the interior of the movable member 35 is filled with the depressed part 40.
  • the bottom-mounted slide 10 has a wide-width structure such that a horizontal web of the movable member 35 is longer than a lateral web thereof. Furthermore, a proportion of defectives formed by roll-forming can be reduced, and the volume of a hollow space 47 formed in each of the lateral sides of the movable member 35 is minimized by the U-shaped depressed part 40. Thus, the strength of the movable member 35 can be enhanced so that it can be used to support a comparatively high load.
  • the movable member 35 includes raceway parts 45.
  • Each raceway part 45 includes the first raceways 37 which are formed at position corresponding to the corresponding second raceways 33 of the stationary member 32.
  • the raceway part 45 further includes webs 36 and 38 which are provided between the first raceways 37.
  • the webs 36 and 38 comprise a horizontal web 36 and a lateral web 38.
  • the horizontal web 36 is longer than the lateral web 38.
  • the depressed part 40 is formed in the horizontal web 36.
  • the depressed part 40 is inserted into the hollow space 47 formed in the movable member 35.
  • the depressed part 40 have a U-shape which has no portion on which stress is concentrated unlike a V-shaped structure in which stress is concentrated on the lower end thereof.
  • the shape of the depressed part 40 is not limited to this and, in other words, it may have any shape including the V shape, so long as the hollow space 47 is filled with the depressed part 40.
  • the depressed part 40 be aligned with the lateral axis of the movable member 35.
  • FIG. 5 is a sectional view showing a process of manufacturing the bottom-mounted slide 30 according to the present invention.
  • the depressed part 40 is formed in the medial portion of the horizontal web 36 so that the volume of the hollow space 47 formed in the movable member 35 can be minimized.
  • the depressed part 40 is formed in the horizontal web 36 by a separate process before the movable member 5 is rolled. Thereafter, the other parts of the movable member 5 are formed by rolls 20 and 20' in the same manner as that of the conventional technique. In this case, it was found that the problems, such as defective forming or imprecise measurements, can be avoided unlike the movable member 5 of the conventional technique. The reason for this is that although compression force is applied to the webs 36 and 38 towards the hollow space 47 when the roll-forming process is conducted, the depressed part 40 withstands and absorbs the compression force.
  • the depressed part 40 when the depressed part 40 has a U-shape and is aligned with the lateral axis of the movable member 35, the depressed part 40 can effectively withstand and absorb the compression force applied to the webs 36 and 38 towards the hollow space 47.
  • the present invention can use the roll-forming method which has been used in the conventional techniques, so that additional expenses are not required.
  • the installation and operation of the slide 30 of the present invention are the same as those of the conventional techniques, therefore further explanation is deemed unnecessary.
  • the raceway part may be easily deformed towards the hollow space of the movable member by horizontal moment during the roll-forming process, so that the shape of the completed raceway part may differ from the original design.
  • the measurements of the raceway part may not be correct and may fall outside a tolerance range. Such incorrectness in the shape or measurements of the raceway part causes a defective movable member.
  • the depressed part 40 formed in the horizontal web 36 of the movable member 35 effectively withstands and absorbs compression force applied to the movable member 35 towards the hollow space 47. Therefore, despite the fact that bottom-mounted slide 30 has a wide width, it can be prevented from deforming attributable to horizontal moment. Furthermore, the measurements of the manufactured product can be prevented from falling outside a tolerance range.
  • the U-shaped depressed parts 40 are respectively formed in the predetermined portions of the lateral sides of the movable member 35 such that the hollow spaces 47 formed in the lateral sides of the movable member 35 are filled with the corresponding depressed parts 40.
  • the first raceways 37 which come into contact with the rolling balls 39 are formed in the lateral sides of the movable member 35.
  • Step S20 is conducted by the same roll-forming method as that of the conventional technique. As such, the depressed parts 40 are first formed before the first raceways 37 are formed, so that the problems of defective forming or imprecise measurements can be prevented.
  • the present invention provides a bottom-mounted slide which is configured such that a defective proportion of roll-forming can be reduced and the strength thereof can be enhanced so that it can be used to support a comparatively high load.
