Description

Technical Field

[0001] The inventive concept relates to an extension table. Background Art

[0002] An extension table is a table whose lateral dimensions can be adjusted by adding or removing one or more extension boards. Extension tables are considered pieces of furniture because they provide flexibility to a home or office. There is always a need to improve the functionality of extension tables. Summary of the invention

[0003] To this end, according to a first aspect, an extension table is provided, comprising a plurality of extension tracks along the table, the extension tracks being used to adjust the size of the table, wherein an extension track of the plurality of extension tracks comprises: one or more middle parts, the one or more middle parts being arranged laterally relative to each other; a first outer part, the first outer part being fixed to a first section of the table and being able to slide relative to the one or more middle parts; a second outer part, the second outer part being fixed to a second section of the table and being able to slide relative to the one or more middle parts, wherein the one or more middle parts, the first outer part and the second outer part of the extension track each comprise a profile of the same design. Thus, all required functions of the extension track of the extension table can be performed by the extension track, wherein each of the middle part, the first outer part and the second outer part comprises a profile of the same design. Using a profile of the same design for all three parts of the extension track can simplify manufacturing, as it reduces the number of different parts required.

[0004] In the case of multiple intermediate sections, each intermediate section may be slidable relative to an adjacent intermediate section.

[0005] The profile of the first outer part and each profile of the one or more intermediate parts may each comprise a sliding member, wherein each sliding member is fixed to an adjacent profile. Thus, for example, in the case of one intermediate part, the sliding member of the first outer part may be fixed to the profile of the intermediate part, and the sliding member of the intermediate part may be fixed to the profile of the second outer part. In the case of multiple intermediate parts, the sliding member of the first outer part may be fixed to the profile of an adjacent intermediate part, and the sliding member of each intermediate part may be fixed to the profile of the next adjacent intermediate part, or in the case of the last intermediate part, to the profile of the second outer part.

[0006] The profile may be made from bent sheet metal, which provides a rigid profile that is still easy to manufacture.

[0007] The profile may comprise a space for accommodating a respective sliding member, wherein the space is open longitudinally along the profile only on one lateral side of the profile, while the opposite lateral side of the profile comprises a wall. This allows space for the sliding member and space for connecting the sliding member to another part of the extension track.

[0008] The profile may include a tubular structural reinforcement section. The tubular structural reinforcement section may be located above the space for accommodating the corresponding sliding member. This combines the structural reinforcement with the space for the plug for attaching the section to the tabletop.

[0009] The first section of the table may be fixed to the first outer part by means of a tubular structural reinforcement section of the profile of the first outer part, and the second section of the table may be fixed to the second outer part by means of a tubular structural reinforcement section of the profile of the second outer part.

[0010] The sliding member of the first outer part can be fixed to the wall of the adjacent profile. Thus, for example, in the case of one intermediate part, the sliding member of the first outer part can be fixed to the wall of the profile of the intermediate part, and the sliding member of the intermediate part can be fixed to the wall of the profile of the second outer part. In the case of multiple intermediate parts, the sliding member of the first outer part can be fixed to the wall of the profile of the adjacent intermediate part, and the sliding member of each intermediate part can be fixed to the wall of the profile of the next adjacent intermediate part, or in the case of the last intermediate part, to the wall of the profile of the second outer part.

[0011] The profile may comprise, on the same lateral side where the space opens, a pair of opposed vertical projections for retaining the sliding member in the space.

[0012] According to a second aspect, an extension table is provided, which includes a first extension rail and a second extension rail, each of which extends laterally along the table for adjusting the size of the table, wherein the first extension rail includes a first horizontal surface extending toward the second extension rail; and the second extension rail includes a second horizontal surface extending toward the second extension rail, so that an extension plate can be stored between the first extension rail and the second extension rail, resting on the first horizontal surface and the second horizontal surface, wherein each of the first horizontal surface and the second horizontal surface is included in an "L"-shaped profile, which can be installed by sliding the "L"-shaped profile into a profile included in the corresponding extension track.

[0013] This provides a convenient way to store one or more extension panels that are not in use temporarily.

[0014] The profile of the extension rail may include a pair of opposing vertical projections, and the "L" shaped profile has projections that mate with the pair of opposing vertical projections for holding the "L" shaped profile in place. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 An extension table 2 is shown.

[0025] The extension table 2 includes a first extension rail 4 and a second extension rail 6, each extending along the length of the table 2 for adjusting the length of the table 2. Each extension rail 4, 6 may include three or more sections that can slide relative to each other to adjust the length of the respective extension rail 4, 6, and thus adjust the length of the table 4 - such as the three sections 4a / 6a, 4b / 6b, 4c / 6c depicted.

[0026] The extension rails 4, 6 are connected at each of their respective ends to each of the two rigid short sections 5, so that each of the short sections 5 and the first extension rail 4 and the second extension rail 6 form a rectangular frame on which the table top 8 rests. At each of the four corners of the frame, a respective table leg 7 is attached to the frame.

[0027] Each of the extension rails 4 , 6 may be made of metal.

[0028] The table top 8 of the table 2 is formed by: a first fixed section 10 located at a first short end of the table 2, a second fixed section 12 located at a second short end of the table 2, and optionally one or more extension panels 14 at the point of use - such as the two extension panels 14 depicted, which can be positioned to rest on the first extension rail 4 and the second extension rail 6 between the first section 10 and the second section 12.

[0029] Figure 2A and Figure 2B The first extension rail 4 is shown separately and in detail. All features and effects described for the first extension rail 4 throughout this disclosure are equally applicable to the second extension rail 6.

[0030] The extension rail 4 comprises a middle portion 4b, a first outer portion 4a and a second outer portion 4c which are arranged laterally relative to each other.

[0031] The first outer portion 4a of the extension rail 4 is connected and fixed to the first section 10 of the table 2 by means of two plugs 100 (see Figure 1 ), and the second outer portion 4c of the extension rail 4 is connected to and fixed to the second section 12 of the table 2 by two different plugs 100.

[0032] The first outer portion 4a and the second outer portion 4c are both slidable relative to the middle portion 4b, as shown by Figure 2B The length of the table 2 can be adjusted by sliding and adding or removing extension plates 14 (see FIG. 14 ) as needed. Figure 2A The extension rail 4 is shown in a retracted configuration corresponding to the extension plate 14 (see Figure 1 ) does not exist, and Figure 2B The extension rail 4 is shown in its extended configuration.

[0033] Figure 34 is an exploded view showing how the first outer part 4a, the middle part 4b and the second outer part 4c fit together to form the first extension rail 4. The middle part 4b, the first outer part 4a and the second outer part 4c of the extension rail 4 each comprise an identically designed profile 106. The second extension rail 6 has corresponding and identical features. The profile 106 can be made of bent sheet metal.

[0034] The profile 106 of the first outer part and the profile 106 of the middle part each comprise at least one sliding member 102 - two sliding members 102 as depicted - which can slide against the respective profile 106, thereby allowing the first outer part 4a to slide against the middle part 4b and the middle part 4b to slide against the second outer part 4c. The sliding member 102 of the first outer part 4a is fixed to the profile 106 of the middle part 4b by a plug 104 fitted into a hole in the profile 106 of the middle part 4b, and the sliding member 102 of the middle part 4b is fixed to the second outer part 4c by a different plug 104 fitted into a hole in the profile 106 of the second outer part 4c.

[0035] Figure 4 and Figure 5 A cross section of an extension rail 4 is shown, comprising each of three identical profiles 106 as a first outer portion 4a, a middle portion 4b and a second outer portion 4c, respectively.

[0036] As depicted, each of the profiles 106 may include a main space 110 that is open longitudinally along the profile 106 only on one lateral side of the profile - as depicted the right side - while the opposite lateral side of the profile includes a wall 107, as depicted the left side. The sliding members 102 of the first outer portion 4a and the middle portion 4b are contained in the respective main space of the respective profile 106.

[0037] As depicted, the sliding member 102 of the first outer part 4a may be fixed to the wall 107 of the profile of the middle part 4b by a plug 104 and the sliding member 102 of the middle part 4b may be fixed to the wall 107 of the profile 106 of the second outer part 4c by another plug 104 .

[0038] The profile 106 may include a pair of opposing vertical protrusions 114, 116 on the same lateral side where the space is open, the protrusions 114, 116 being used to retain the sliding member 112 in the space. As depicted, the protrusions may include bends in the bent metal sheet of the profile 106.

[0039] As depicted, above and below the main space, there may be a respective upper closed tubular reinforcement section 108 and lower closed tubular reinforcement section 112. As depicted, each of the closed tubular reinforcement sections 108, 112 may have a square cross-section. Figure 1 ) can be connected and fixed to the first outer part 4a of the extension rail 4 through the upper tubular structure reinforcement section of the profile 106 of the first outer part 4a through the plug 100, and the second fixed part 12 of the table 2 can be connected and fixed to the second outer part 4c of the extension rail 4 through the upper tubular structure reinforcement section 108 of the profile 106 of the second outer part 4c.

[0040] As depicted, sliding may occur through direct contact between the material of the sliding member 112 and the profile 106, or, for example, through wheels or the like.

[0041] Figure 6 , Figure 7 and Figure 8 Shows such a configuration, in which, in addition to the above-incorporated Figures 1 to 5 In addition to the detailed description, the first extension track 4 also includes a first horizontal surface 118 extending toward the second extension track 6; and the second extension track 6 includes a second horizontal surface 118 extending toward the first extension track 4, so that Figure 6 As shown by the arrows in Figure 8 As shown in the figure, one or more extension panels 114 can be stored between the first extension rail 4 and the second extension rail 6, and the extension panels 114 rest on the first horizontal surface 118 of the first extension rail 4 and the second horizontal surface 118 of the second extension rail 6. After the user places the one or more extension panels on top of the first horizontal surface 118 and the second horizontal surface 118, the first section 10 and the second section 12 can be combined together by sliding the extension rails 4 and 6, so that the one or more extension panels 114 rest under the tabletop 8 formed by the first section 10 and the second section 12 and out of sight.

[0042] like Figure 7 As can be seen in the figure, the first horizontal surface is comprised in a first "L" shaped profile 124, which can be installed by sliding the "L" shaped profile 124 into the profile 106 of the second outer portion 4c of the extension track. The vertical projections 114 and 116 of the profile 106 abut against the matching projections 120 and 122 of the "L" shaped profile 124, thereby holding the "L" shaped profile 124 in place.

[0043] In the same way ( Figure 7), the horizontal surface 118 of the second extension rail 6 is formed by a second “L”-shaped profile in the profile 106 that can be mounted to the second outer portion of the second extension rail 6.

[0044] The inventive concept has mainly been described above with reference to exemplary embodiments. However, as readily appreciated by a person skilled in the art, other embodiments than the ones disclosed above are equally possible within the scope of the inventive concept as defined by the appended patent claims.
