Definitions

  • the present invention relates to a cabinet drawer that has a drawer slide and that has improved load carrying capacity as well as precision guided movements.
  • sheet metal cabinet drawers that use side-mounted drawer slides are made to a limited width so that when heavy articles are kept, sagging or distortion of the base of the drawer is minimal.
  • wide side mounted sheet metal drawers are needed sagging or distortion of the base of the draw is common when heavy articles are kept in the drawer.
  • either the base of the drawer has to be made of thicker material or it has to be reinforced with strengthening sections. This not only increases the weight and cost of the drawer, but also reduces the effective storage space of the drawer.
  • Another problem associated with a wide drawer is that the guiding capabilities of the drawer against sideway and/or swinging movement of the drawer tend to be less effective when the sideway guides are spaced far apart.
  • bottom mounted drawer slides Whilst many types of bottom mounted drawer slides exist, they are typically used as the sole slides to guide the drawer movement and support the drawer load. They are not designed to receive part of the load acting on a pair of side-mounted slides of a sheet metal drawer across the drawer base. Nor are they designed to reduce the sag or distortion of the sheet metal base panel of the drawer, particularly when the width of the drawer is very wide, such as 1 meter or more in width. In this case, the lack of side support for the drawer may increase the likelihood of sagging or distortion. Additionally, conventional drawer slides are often constructed as distinct, separate parts, and do not include the construction of the drawer as part of the sliding mechanism.
  • US Patent No. 4,441,773 aims to support a wooden drawer constructed with substantial front, rear and side panels or walls defining a rectangular enclosure, and the bottom of the drawer being constructed with a thin sheet of fiberboard or wood.
  • the slide of US Patent No. 4,441,773 avoids attaching one of the sliding sections to the thin bottom sheet.
  • a cabinet drawer fitted with two drawer slides on its two sides and a supplementary stationary drawer slide.
  • the supplementary drawer slide is located on the underside face of the drawer.
  • the cabinet drawer is made from sheet metal.
  • one part of the supplementary drawer slide is formed on the horizontal bottom face of the drawer and another part mounted on the inner bottom face of the cabinet, at mid-span position.
  • This supplementary slide serves as a slide additional to the common drawer slides that are mounted on the side faces of the drawer and stationary drawer cabinet.
  • the supplementary slide comprises a rolling or sliding element assembly and an inverted U-shaped track in the bottom face of the drawer.
  • the rolling or sliding element assembly comprises at least two arrays of anti-friction bearings or rollers or low friction sliding pads, and they are mounted on a rail.
  • one array of anti-friction elements is mounted in a position to support the downward load that transmits through the base of the drawer, and a second array of anti-friction elements is mounted in a position to confine the sideway movement of the drawer in the direction perpendicular to the normal opening and closing movement of the drawer.
  • the rail is attached to the inside base of the drawer cabinet.
  • the rail is metal
  • the inverted U-shaped track is formed as part of the bottom panel of the drawer. This maximizes the storage space of the drawer by maintaining minimum clearance between the drawer and the stationary cabinet. It also forms a reinforcing structure in the form of a web to support heavy load in the drawer.
  • an additional inverted U-shape section can be mounted into the base of the drawer.
  • the additional inverted U-shaped section is mounted inside the inverted U-shaped track.
  • the additional inverted U-shaped section is made of sheet metal.
  • the additional inverted U-shaped section is welded to the base of the drawer.
  • the additional inverted U-shaped section is fixed to the base of the drawer.
  • the additional inverted U-shaped section is removable from the base of the drawer.
  • a cabinet drawer comprising a cabinet and a sliding drawer; wherein the sliding drawer is mounted with two sets of sliding guides on two opposite sides of the drawer, and a supplementary sliding guide on a face of the drawer located between the two opposite sides.
  • the two opposite sides are located on sides of the drawer.
  • the face of the drawer is perpendicular to the opposite sides.
  • the face of the drawer connects the opposite sides together.
  • the face of the drawer is on the base of the drawer.
  • the supplementary sliding guide is located at the mid-point of the face.
  • the supplementary sliding guide comprises a channel in which anti-friction bearings, rollers or pads are received.
  • the bearings, rollers or pads slide on the inner faces of an inverted U-shaped channel.
  • the inverted U-shaped channel is built onto the bottom face of the drawer.
  • the U-shaped channel is integrally formed with the drawer body.
  • the bearings, rollers or pads are fixed to a face of the cabinet.
  • the bearings, rollers or pads are fixed to the face of the cabinet so that the sliding guide aligns with the bearings, rollers or pads in use.
  • the bearings, rollers or pads are located within an omega-shaped channel.
  • each of two sets of sliding guides includes an engaging portion on the drawer and a receiving portion on the cabinet.
  • the engaging portion is adapted to be received within and run along the receiving portion in use.
  • the cabinet drawer 11 of the first preferred embodiment comprises an outer cabinet housing 1, a sliding drawer body 2 that is adapted to slide in and out of the cabinet housing 1, and drawer slide sets 8 mounted on the sides 15 of the drawer body 2.
  • the drawer slide sets 8 include a receiving portion 18 in the form of a channel mounted to the internal walls of the outer cabinet housing and an engaging portion 28 in the form of a rib adapted to sit inside the channel portion 18. The rib 28 slides within the channel portion 18 to move the drawer 2 in and out of the outer cabinet housing 1.
  • drawer slides 8 are envisaged by the present invention.
  • differently profiled channels could be used or a telescoping slide could connect the sides 15 to the internal side walls of the cabinet housing and still be within the scope of the present invention.
  • An inverted U-shape channel 3 is located on the base 14 of the drawer 2.
  • the inverted U-shaped channel 3 forms a channel matching and being able to slide against the sliding element fitted in an omega-shaped channel 4.
  • the inverted U-shape channel 3 is typically constructed as part of the base 14 of the drawer 2.
  • the drawer 2 includes two sides 15 and a base 14.
  • the base 14 extends between and is connected to the two sides 15.
  • intermediate portions can connect the base 14 to the sides 15.
  • an angled plate can connect the base 14 to the two sides 15.
  • Other alternative arrangements of the sides 15 and base 14 are considered by the present invention, provided that the base 14 includes a guide channel and the base 14 connected to the sides 15 including drawer slides 8.
  • the inverted U-shaped channel 3 is formed as part of the base 14 of the drawer 2.
  • the U-shaped channel 3 can be a separate piece that is attached to the base 14, through welding, screwing, or otherwise as would be understood by the skilled addressee.
  • drawer slide sets 8 are formed as part of the sides 15 of the drawer 2.
  • drawer slide sets 8 can be a separate piece that is attached to the sides 15, through welding, screwing, or otherwise as would be understood by the skilled addressee.
  • the U-shaped channel 3 is located at the mid-point across the width of the drawer 2.
  • the U-shaped channel 3 can be located at any point across the width of the drawer 2.
  • Omega shaped channel 4 piece is adapted to be mounting onto the internal face of the cabinet 1 which the drawer 2 sits on and is located to slidingly engage with the U-shaped channel 3.
  • Omega shaped channel 4 consists of rectangular shaped holes 5 on its faces, through which a portion of ball bearings 6 and 7 pass through.
  • the portion of the ball bearings 6 that extends outside the omega shaped channel 4 is in contact with the vertical inner faces 23 of the inverted U-channel 3, and constrains the sideway movement of the drawer 2.
  • the portion of ball bearings 7 that extends outside the omega shaped channel is in contact with the horizontal underside 13 of the inverted U-shape channel 3, and provides support to the load in the sliding drawer 2.
  • the omega-shaped channel 4 can be mounted to the internal face of the cabinet 1, through welding, snap fitting, clips, screwing or otherwise as would be understood by the skilled addressee.
  • rollers, or other devices understood by the skilled addressee may be attached to the inside of the cabinet 1 to coincide with and run along the U-shaped channel 3.
  • the inverted U-shaped channel 3 that is configured on the base panel of the drawer 2 provides reinforcement to the base panel and avoids sagging of the base 14 and other drawer 2 panels under heavy load. Consequently, minimum clearance can be achieved between the underside of the drawer 2 and the inner bottom face of cabinet 1. This increases the effective storage volume of the drawer. Also, bearings 6 are arranged in such a way that obeys the "narrow guide principle" , ensuring that the sideward swing of the drawer is kept to the minimum.
  • channel 3 has been described as U-shaped, the present invention envisages alternative shapes such as V, funnel, tapered or otherwise as would be understood by the skilled addressee.
