Definitions

  • the present invention relates generally to slide rails for drawers of OA equipment, furniture and the like and more specifically to those simplified in structure.
  • Japanese Patent Laying-Open No. 59-67913 discloses a slide rail structured including a supporting rail attached to a body receiving a drawer and a drawer rail attached to a drawer, with rollers provided therebetween to ensure reliable movement in longitudinal and lateral directions, respectively.
  • This conventional slide rail requires that between the supporting and drawer rails there exist rollers providing two functions. This increases the number of the parts of the slide rail and consequently complicates its structure and also increases its cost.
  • the present invention has been made to solve the above disadvantage and it contemplates a slide rail simplified in structure.
  • the present invention provides a slide rail including an external rail, an internal rail and a roller arranged between the external rail and the internal rail, the external rail and the internal rail being slideable relative to each other, wherein the external rail accommodates the internal rail, between a side of the internal rail facing outward and that of the external rail facing inward there being provided opposite spaces each receiving the roller having an axis for rotation traversing a plane in which the slide rail slides, the axis for rotation being spaced from each other by a distance reduced as the axis for rotation comes closer to the external rail.
  • the external rail includes a body extending in a direction in which the slide rail slides, a flange raised at each of opposite sides of the body of the external rail, and a raised portion provided at each of opposite ends of the flange of the external rail to extend inward facing the body of the external rail.
  • the internal rail includes a body extending in the direction in which the slide rail slides, a flange raised at each of opposite sides of the body of the internal rail, and a raised portion provided at each of opposite ends of the flange of the internal rail to extend outward facing the body.
  • the external rail accommodates the internal rail to have their respective internal sides facing each other, an outer side of the flange and raised portion of the internal rail and an inner side of the flange and raised portion of the external rail together define opposite spaces each accommodating the roller with a rolling surface in contact with the flange of the internal rail and the flange of the external rail.
  • the roller each has an axis for rotation traversing the plane in which the slide rail slides and spaced from each other by a distance reduced as the axis for rotation comes closer to the external rail.
  • the rails With the space accommodating the roller, if an external force is exerted to move the external and internal rails away form each other the rails can have their respective raised portions together pinching the roller to prevent the rails from moving away from each other.
  • the flange of the external rail and the flange of the internal rail each have a surface contacting a rolling surface of the roller, parallel thereto.
  • a portion of the raised portion of the external rail closer to the roller and that of the raised portion of the internal rail closer to the roller are each substantially parallel to a side surface of the roller.
  • the roller With the rails having a surface contacting the roller, parallel thereto, the roller can smoothly rotate to reduce the resistance between the external and internal rails as they slide. Thus the slide rail's function can further be enhanced.
  • the space receives more than one roller integrally supported by a supporting rail provided between the external and internal rails.
  • the supporting rail supporting the rollers integrally can facilitate assembling the slide rail and also allows the rollers to integrally function to further enhance the slide rail's function.
  • slide rail is structured as described with reference to Figs. 1A and 1B and 2.
  • the present embodiment provides a slide rail including an external rail 1 and an internal rail 2. Between external and internal rails 1 and 2 a roller accommodating space is provided to arrange therein a plurality of rollers 4 to allow external and internal rails 1 and 2 to be slideable relative to each other.
  • External rail 1 includes a body 1a, a flange 1b provided at opposite sides of body 1a, and a raised portion 1c provided at flange 1b.
  • Body 1a extends in a direction in which the rail slides.
  • Flange 1b is raised at the opposite sides of body 1a.
  • Raised portion 1c is each provided at an end of flange 1b to extend inward facing body 1a.
  • Internal rail 2 includes a body 2a, a flange 2b provided at opposite sides of body 2a and a raised portion 2c provided at flange 2b.
  • Body 2a extends in a direction in which the rail slides.
  • Flange 2b is raised at the opposite sides of body 2a.
  • Raised portion 2c is each provided at an end of flange 2b to extend outward facing body 2a.
  • external rail 1 accommodates internal rail 2 such that the rails have their respective internal sides facing each other.
  • An outer side of flange 2a and raised portion 2c and an inner side of flange 1b and raised portion 1c define a space 10A for accommodating a roller 4.
  • Roller 4 has a rolling surface 4a contacting a contact surface 20b of flange 2b and a contact surface 10b of flange 1b. Furthermore, roller 4 has an axis for rotation L1 traversing the plane in which the rail slides and, at the opposite sides, spaced from each other by a distance reduced as it comes closer to external rail 1. In the present embodiment, as shown in Fig. 2, upper and lower rollers 4 have their respective axes for rotation L1 having inclinations of ⁇ ° and - ⁇ °, respectively, relative to an axis L perpendicular to body 1a of the external rail.
  • contact surfaces 10 b and 20b are provided parallel to rolling surface 4a of roller 4, as indicated by lines L1 and L3.
  • Supporting rail 3 is provided between external and internal rails 1 and 2 to support and thus integrate roller 4.
  • Supporting rail 3 includes a body 3a, a bent portion 3b provided at opposite sides of body 3a and a raised portion 3c raised at an end of bent portion 3b.
  • Raised portion 3c has a plurality o guide holes 3d provided lengthwise to accommodate roller 4.
  • slide rail thus configured, with roller 4 accommodated in space 10A, receives an external force to move external and internal rails 1 and 2 away from each other, raised portions 1c and 2c together can pinch roller 4 to prevent external and internal rails 1 and 2 from moving away from each other.
  • supporting rail 3 supporting roller 4 integrally can facilitate assembling the slide rail and also allows roller 4 to integrally function to provide the slide rail with a further enhanced function.
  • a portion of raised portion 1c closer to roller 4 and that of raised portion 2c closer to roller 4 are each substantially parallel to a side surface of roller 4.
  • roller 4 can smoothly rotate to reduce the resistance between external and internal rails 1 and 2 as they slide.
  • the slide rail's function can further be enhanced.
  • Fig. 1A shows a position with internal rail 2 maximally drawn out of external rail 1. In this position a mechanism is adapted to prevent internal rail 2 from coming off external rail 1. This mechanism will now be described with reference to Figs. 3 and 4.
  • internal rail 2 has the other end provided with a bent portion 2d extending toward external rail 1 and abutting against the other end of supporting rail 3.
  • external rail 1 has one end provided with a bent portion 1d extending toward internal rail 2 and abutting against one end of supporting rail 3.
  • supporting rail 3 has the opposite ends sandwiched between external and internal rails 1 and 2 to limit the movement of internal rail 2 toward one end.
  • the internal rail's bent portion 2d abuts against the external rail's bent portion 1d to limit the movement of internal rail 2 toward the other end.
  • Fig. 6 shows an example of a slide rail as configured above with a drawer attached thereto.
  • the drawer has a body 100 with external rail 1 fixed thereto by a screw 300 or the like.
  • Internal rail 2 and supporting rail 3 each have a geometry avoiding the head of screw 300.
  • Fixed to a drawer 200 is internal rail 2.
  • While the present slide rail is typically applied to such a drawer as shown in Fig. 6 it can also be applied with external rail 1 fixed to a ceiling and internal rail 2 having a lightning appliance attached thereto to readily change the position of the lightning appliance.
  • the present invention essentially provides a slide rail including an external rail, an internal rail and a roller arranged between the external and internal rails, the external and internal rail being provided slideably relative to each other, wherein the external rail accommodates the internal rail, between a side of the internal rail facing outward and that of the external rail facing inward there are provided opposite spaces each receiving the roller having an axis for rotation traversing a plane in which the slide rail slides, and also spaced from each other by a distance reduced as it comes closer to the external rail.
  • the present slide rail can have a single roller having the above-described two functions and it can thus be simplified in structure.
  • the external, internal and supporting rails can each have a simple geometry and they can thus be produced through press work to reduce the cost for producing the slide rail.
