Definitions
- the invention relates to a method for assembling a leg for a piece of furniture or the like comprising two leg parts which are telescopically movable relative to each other and which at least partially engage round each other.
- Pieces of furniture such as desks and worktables, are in many cases supported by legs, which each comprise two leg parts which are telescopically movable relative to each other so as to enable vertical adjustment of worktables or the like supported by such legs.
- Leg parts of this kind are generally folded from sheet material, whereby it is not possible to maintain very fine tolerances. A problem which occurs thereby is to ensure in a simple manner that the telescopically movable legs are guided without any play between them.
- a guide member is connected to a first leg part, which guide member is provided with at least one projecting part, which projects from said first leg part in such a manner that when one leg part is slided over the other leg part, said projecting part will be shaved off by a cutting edge which lies substantially in one plane with a wall part of said second leg part which bounds a gap between said leg parts.
- the initially oversize projection is automatically cut or shaved off when one leg part is slided over the other, in such a manner that the measure to which said projection projects with respect to one leg part corresponds with the gap which is present between the outer side of said one leg part and the inner side of the other leg part, as a result of which it can be automatically effected in a simple and quick manner during assembly that the leg parts are guided without any play between them.
- the leg which is shown in Figure 1 comprises a base 1, an upwardly extending leg part 2, which is secured to said base 1, and a leg part 3, which is slided over leg part 2 with its bottom end.
- the two leg parts have a substantially elongated section with rounded ends.
- a guide member 4 comprises a dish-shaped shell part 5.

Abstract
Description
- The invention relates to a method for assembling a leg for a piece of furniture or the like comprising two leg parts which are telescopically movable relative to each other and which at least partially engage round each other.
- Pieces of furniture, such as desks and worktables, are in many cases supported by legs, which each comprise two leg parts which are telescopically movable relative to each other so as to enable vertical adjustment of worktables or the like supported by such legs. Leg parts of this kind are generally folded from sheet material, whereby it is not possible to maintain very fine tolerances. A problem which occurs thereby is to ensure in a simple manner that the telescopically movable legs are guided without any play between them.
- According to the invention this can be accomplished in that a guide member is connected to a first leg part, which guide member is provided with at least one projecting part, which projects from said first leg part in such a manner that when one leg part is slided over the other leg part, said projecting part will be shaved off by a cutting edge which lies substantially in one plane with a wall part of said second leg part which bounds a gap between said leg parts.
- By using the method according to the invention, the initially oversize projection is automatically cut or shaved off when one leg part is slided over the other, in such a manner that the measure to which said projection projects with respect to one leg part corresponds with the gap which is present between the outer side of said one leg part and the inner side of the other leg part, as a result of which it can be automatically effected in a simple and quick manner during assembly that the leg parts are guided without any play between them.
- The invention will be explained in more detail hereafter by means of a few embodiments of legs and parts associated therewith, which are diagrammatically illustrated in the accompanying figures.
- Figure 1 is a diagrammatic view of a leg comprising leg parts which are telescopically movable with respect to each other.
- Figure 2 is a larger-scale sectional view of parts of the two leg parts engaging round each other.

- Figure 16 is a bottom view of Figure 15.
- Figure 17 is a plan view of a cutting element.
- Figure 18 is a sectional view of Figure 17, seen along line XVIII-XVIII.
- Figure 19 shows the two facing ends of two leg parts for telescoping said leg parts into each other.
-
- The leg which is shown in Figure 1 comprises a
base 1, an upwardly extendingleg part 2, which is secured to saidbase 1, and aleg part 3, which is slided overleg part 2 with its bottom end. As will be apparent from Figure 2, the two leg parts have a substantially elongated section with rounded ends. - Two
guide members 4, one positioned above the other, which are preferably made of plastic material, are secured to each of the rounded ends ofinner leg part 2. As is shown in more detail in Figures 5 - 7, such aguide member 4 comprises a dish-shaped shell part 5. Attached to opposing ends of saidshell part 5 are three pairs of projectingribs 6 and 7 respectively, whose height increases in a direction away from said ends.Ribs 8 having a constant height are furthermore attached to the centre part of the dish. As will be apparent in particular from Figure 5, eachrib 8 is positioned centrally between a pair ofribs 6 and 7, seen in the longitudinal direction of the dish. - A projection 9 is formed on the inner side of
dish 5 facing away fromribs 6, 7. -
Guide members 4 can be fixed toleg part 2 by inserting the projections 9 into corresponding holes formed inleg part 2. The boundary wall ofshell part 5 that faces away from ribs 6 - 8 is thereby placed in closely abutting relationship with the outer side ofleg part 2. - When the two
leg parts elements 10 are attached, possibly detachably, to the bottom end ofouter leg part 3. - As will be apparent from Figures 8 - 10, such a cutting element comprises a dish-
shaped part 11, which is provided at its lower end with athickening 12, whosebottom edge 13 forms a cutting edge. As will be apparent in particular from Figure 4, the dish-shaped part 11 of acutting element 10 is placed against the outer side ofouter leg part 3, in such a manner that the thickenedpart 12 ofcutting element 10 abuts against the bottom edge of saidleg part 3. - When the leg is to be assembled,
leg part 3 is slided overleg part 2 in the direction indicated by arrow A, as is shown in more detail in Figures 3 and 4. Thecutting edge 13, which is at least substantially in line with the inner wall ofleg part 3, will shave or cut off parts of theribs 8, which are of oversize, and possibly parts ofribs 6 and 7, in such a manner that the remaining parts of said ribs bridge the gap 14 (Figure 2) which is present between theengaging parts leg parts - Figure 11 shows a leg construction, wherein
leg parts guide members 17 are clamped down in recesses provided in the corner points ofinner leg part 15, as is shown in Figures 12 and 13. As is shown more particularly in Figures 15 and 16, such a guide member, which is preferably made of plastic material, comprises abody 18 having a more or less rectangular section, in two corner points of which projectingribs 19 are provided.Projecting cams 20 are furthermore provided at the ends of the body, which cams abut against the inner wall of the leg part if the guide member is present in the leg part in question. - As will be apparent in particular from Figure 13, the projecting
ribs 19 project from theinner leg part 15. - As will furthermore be apparent from Figure 11, two
guide members 17 are provided one above the other in each of the corner points of the inner section part in this embodiment as well. - As is shown in more detail in Figure 19, a
cutting element 21 as shown in Figures 17 and 18 is provided, possibly detachably, in each of the corner points ofouter leg part 16. As appears from said Figures 17 and 18,cutting element 21 comprises twolegs thickening 24, whoselower edge 25 forms a cutting edge. - The cutting elements are attached to the bottom end of outer leg part 16 (Figure 19) in such a manner that said
thickenings 24 abut against the lower edge of therespective leg part 16, whereby the cutting edges will at least substantially be in line with the inner wall ofleg part 16. - When the leg is to be assembled,
outer leg part 16 can be slided overinner leg part 15 in the direction indicated by arrow B, as is shown in Figure 19, whereby the initiallyoversize ribs 19 will be cut of shaved off byknife edges 25, so that the remaining parts of theribs 19 will fill thegap 26 which is present between the twoleg parts 15 and 16 (Figure 14) entirely, thus guiding theleg parts - Of course variations and/or additions to the shape and location of the guide members are possible, depending on the shape of the leg parts which are telescopically movable relative to each other. Furthermore it will be possible to attach the guide members to the outer leg part rather than to the inner leg part, in which case the cutting elements will be attached to the inner leg part in a corresponding manner.
- Another possibility is to design the lower edge of the leg part which is slided over or into the leg part comprising the guide members as a knife edge, so that the individual cutting elements as referred to above can be left out.
