Definitions

  • the present-invention relates to a sliding drawer for tables and office desks,- adapted,to be secured upon the 16.
  • Both guiding pins 17 and 18 are provided with a ring shaped groove 21. Inserted into the ring shaped groove 21 of the guiding-pin 17 is a rubber ring 22.
  • the stationary carrying drawing is secured upon a wooden plate 23 (FIG. 1) of thedesk, by means of two pairs of expansion bolts indicated generically by 24 (FIG. 3).
  • the expansion bolt 24 is made of a metal portion comprising a screw;v 29and an head comprising an enlarged portion ora thumb knob. 26, a pin'27, and a flange 28.
  • Some drawer types are known the securing operation 7 whereof upon the desk plate is carried outby guides inserted into grooves providedon the drawer sides. These guides require a certain precisiondegreein the manufacturing operations in orderto obtain-a satisfactory sliding motion of the drawenwhereby such guiding means generallyvresults in being relatively expensive.
  • FIG. 1 is a partial sectional-perspective view of adesk plate with a stationary carryingdrawer according to the model
  • FIG. 2 is a side sectional view of the drawer
  • FIG. 3 is a detail of the drawer.
  • the drawer which is generically designedby 50 (FIG. 1), is particularly of the-stationary carrying type and is made of a single part of plastic material.
  • the drawer is divided inside into a first section I and into three other sections 2 which are smaller than the previous one.
  • the drawer is made of a bottom 3, a front wall 4, a rear wall 6 and side walls 7 divided so as to build up a chamber 8 on each drawer side.
  • Each of the two chambers 8 is divided transversely by a vertical wall 9 (FIG. 2) and by a horizontal wall 11 provided with two horizontal guiding slits 16 (FIG. 1).
  • a vertical wall 9 FIG. 2
  • a horizontal wall 11 provided with two horizontal guiding slits 16 (FIG. 1).
  • three inclosures arebuiltup, a first guiding inclosure 12 (FIG. 2) located on the top side of the drawer and two inclosures Band 14 located on the lower side of the drawer.
  • the section iron 19 has a sectionsubstantially rectangular having an upper wall provided with a longitudinal slit 38 (FIG. 1).
  • the section iron 19 (FIG. 2) may slide with respect to'the-drawer through'a first stroke being equal to the length of the two longitudinal slits between the cylinderr-3 l. and the nut 32 and being provided with two turned over lugs building up two triangular teeth 33 (FIG. 1), which grasp the nut so as to prevent its rotation with respect to the'flange 34.
  • the expansion bolts 24, areinserted into the blind holes 36 of the plate 23 (FIGS. 1 and 2), driving the teeth 33 into the endof the hole 36 and thus locking the nut 32 against the rotation.
  • the locking operation of the expansion bolt.24 is executed by turning the knob 26 thus causingthe screwi29 to be screwed into the nut '32 and the rubbercylinder 31 to be expanded.
  • the knobs 26 havecthe object to support the drawer and are inserted, by.--pairs, unto the section iron 19 (FIG. 1).
  • the slit 38 ofthesection irons 19 has a length which is slightly larger than the diameter of the pin 27 (FIG. 3) andthe'internal width of the guiding means 19 is slightly larger than the diameter of the knob '26, so that the guides 19 areable'to slide with respect to the knobs 26.
  • One end 39 of the sectioniron 19 is closed by a plastic locking member 41, in order to prevent the knobs 26 from beingtaken outfrom the front side.
  • the other I end .42 of the section irons 19 is slightly embossed on to sidewalls 43(FIG. 1) so that the width of the section iron 19 is slightly smaller than the diameter of the knobs 26 on said end .portion 42.
  • the assembling of the drawer first requires that the expansion bolts 24are locked into the corresponding holes 39 and then that the knobs 26 are inserted inside the section irons 19 through the end portion 42 by forcing the embossed portions 43 by a moderate manual pressure.
  • the embossed portions 43 prevent the drawer from being taken out. when normally used.
  • the section iron 19 is capable of sliding with respect to the pins 27 through a second stroke which is equal to the difference between the length of the same section iron 19 and the separation existing between-the two knobs 26. This sliding travel, added to the one recited sliding-travel between the section iron 19 andthe drawer 50, allows the drawer to open and close completely.
  • the inclosure 13 (FIG. 2) has dimensions which are slightly smaller thanthe adjacentone 14, this causing the rubber member 22 to strike against the wall 6 when What I claim is:
  • a sliding drawer device for tables and office desk comprising a desk plate having a top surface and a bottom surface, said bottom surface housing two pairs of reciprocally parallel blind holes, a drawer assembly including a drawer having two side walls, two guiding section irons, means connecting said side walls to said two guiding sections irons below said two pairs of holes and parallel thereto, respectively, and two pairs of expansion bolts inserted in said blind holes, each of said irons including an upper wall defining a longitudinal slit, and said pair of expansion bolts including a first flange, a screw connected to said first flange, an expandable sleeve surrounding said screw, and a head joined to said screw for compressing said sleeve against said first flange for locking said expandable sleeve in said hole, said head comprising a second flange contacting said bottom surface of said desk plate, a pin projecting from said second flange, and slidably engaging the slit below the upper wall of said section irons and an enlarged portion for slid
  • said connecting means includes a pin and slot connection comprising two pairs of guiding pins secured to said second irons and two other walls of said drawer connected to said 'two side walls, each of said other walls having a guiding slit thereon engaging said guiding pins for slidably guidingsaid section irons with respect to said drawer.
  • a sliding drawer device wherein said section irons have a substantially rectangular cross section and each of said side walls includes two vertical walls, each of saidother walls comprising a horizontal wall connecting said two vertical walls to define a housing on which said section irons are located.
  • a sliding drawer assembly for tables and office desk of the type including a plate having a top surface and a bottom surface, said bottom surface including two pairs of blind holes aligned in two parallel rows, two pairs of expansion bolts locked in said blind holes, a sliding drawer comprising a bottom wall and two side walls perpendicular to said bottom wall, each of said side walls including two vertical walls and a horizontal wall interconnecting said two vertical walls to define an upper enclosure and a lower enclosure, said horizontal wall including two horizontal slits, two guiding section irons, two guiding pins fixed to said section irons and each engaged in one of the two horizontal slits for guiding each one of said section irons on said upper enclosure through a first stroke substantially equal to the length of said horizontal slits, said section irons being provided with two corresponding longitudinal slits each slidably engaged by one pair of said expansion bolts for slidable movement with respect to said desk plate through a second stroke, said first and said second strokes enabling said drawer to be completely extracted from said plate.
