Problems solved by technology

[0004] The first example of prior art has an obvious flaw: when the table is in its compact position, the pivoting edge of the table top covers the area between the legs
To solve this problem, low-friction solutions requiring movable sliding members such as guide rollers, etc. have been proposed, but these types of components have the disadvantage of high cost

Embodiment 1

[0171] Using the test procedure described above, the friction resulting from the application of various lipophilic compositions to anodized painted aluminum profiles was determined. The resulting kinetic friction (average value from three test series) is recorded and compared with that of an anodized aluminum profile provided with lacquer but not coated with any lipophilic composition (=control). The results are provided in Tables 1 and 2 below.

[0172] Table 1 - Fatty acids in liquid paraffin

[0173]

[0174] MA5% / 10% / 30% = 5% by mass / 10% by mass / 30% by mass of myristic acid in liquid paraffin

[0175] PA10% = 10% by mass of palmitic acid in liquid paraffin

[0176] SA10% = 10% by mass of stearic acid in liquid paraffin

Embodiment 2

[0190] By using the test procedure described above, the friction generated under various loads (5N, 10N and 20N, respectively) using liquid paraffin as a coating of the lipophilic composition was determined. Increasing the load did not lead to an increase in friction. In contrast, the lowest load (5N) exhibited the highest friction (friction value 0.052 (at 5N) vs. friction value 0.045 (at 10N) / 0.046 (at 20N)).

Embodiment 3

[0192] In another experiment, corresponding aluminum poles without any paint were used. The use of 10 mass % palmitic acid in liquid paraffin as a lubricant on an unpainted rod produced a kinetic friction of 0.1132, i.e. more than 100% higher than the corresponding kinetic friction obtained with a painted aluminum rod (see Table 1, 0.042 and 0.047).

Abstract

An extendable table sliding system (10) for an extendable table (1) is provided. The sliding system comprises at least two parts (110, 120) being moveable relative each other and together forming at least a part of the extendable table sliding system (10), wherein one of said at least two parts (110, 120) comprises at least one sliding surface (140, 340, 440, 640) being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer (141c) with a lowered friction.

Description

technical field [0001] The present invention relates to extendable tables. More specifically, the present invention relates to extendable table sliding systems for extendable tables and extendable tables having such sliding systems. Background technique [0002] Extendable tables have been around for a long time, and various extension techniques have been proposed to provide a robust and easy-to-operate solution. For example, it is common to pivotally connect the longitudinal edges of the table top to the main central portion. Movable frame members such as rods that pivot in a horizontal plane or rods that slide in a horizontal plane may be arranged to support the collapsible edges of the tabletop to extend the table. When a more compact table is desired, the longitudinal edges of the tabletop can be lifted slightly upwards to allow the movable frame members to retract. When the edge of the tabletop is released downward, it will pivot fully downward to rest in its vertica...
