DESCRIPTION OF PREFERRED EMBODIMENTS
(25)
(26) The frame 1a shown detached from the table top 11 in
(27) The two front arms 6, 7 are additionally fastened on the first, front connecting element 12, which is shown in an enlarged manner and schematically in a view from the front in
(28) In the axial direction L54, the front, left coupling element 50, which is shown in
(29) The further preferred exemplary embodiment of the coupling element 50 in
(30) The two longitudinal rods 54, 55, in the exemplary embodiment of
(31) According to
(32) In the exemplary embodiment shown, the arms 6, 7, 8, 9 are fastened further outside, i.e. further forward or rather further rearward on the respective connecting element 12, 13 than the corresponding legs 2, 3, 4, 5.
(33) In addition, each connecting element 12, 13 comprises two central tubular sleeves 34, 35, which are arranged one above the other and parallel to one another, for receiving one end of a connecting rod 14, 15 each, said connecting rod connecting the front connecting element 12 to the rear connecting element 13. Said central tubular sleeves 34, 35 are arranged transversely with respect to the direction of extension of the plate 20 or rather with respect to the plane of the plate 20 of the respective connecting element 12, 13, or rather pierce the plate 20 to some extent. The central tubular sleeves 34, 35 in the exemplary embodiment shown are closed on the front side 22 of the front connecting element 12, or rather on the rear side of the rear connecting element 13. The two connecting rods 14, 15 extend along their longitudinal axes L14, L15 from front to rear and are arranged one above the other, spaced apart from one another, thereby forming a space 48.
(34) The front legs 2, 3 and rear legs 4, 5 are each arranged with respect to one another at a first acute angle 1 which, in the present exemplary embodiment, is approximately 80 degrees. The front arms 6, 7 are also arranged with respect to one another at a second acute angle 2, which is smaller than the angle 1 spanned between the front legs 2, 3 and, in the present exemplary embodiment, is approximately 70 degrees.
(35) In the exploded view in
(36) The way in which the elastic cord 16 runs is explained below as an example by way of the two front legs 2, 3, but is also applicable in an analogous manner to the way in which the elastic cord 17 of the rear legs 4, 5 runs.
(37) As can be seen in the exploded representation in
(38) The tube plug 42 forms the closure on the arms 6, 7, 8, 9 or rather the upper end of the arm 6, 7, 8, 9. A foot 44 is additionally mounted on the legs 2, 3, 4, 5 over the end of the respective leg 2, 3, 4, 5 which is closed by way of the tube plug 42. In this case, the end of the leg 2, 3, 4, 5 is received in a blind hole 47 in the foot and is fastened therein, for example stuck down or pressed thereon. The foot 44 shown in
(39) Each connecting element 12, 13, of which the front connecting element 12 is shown in more detail in
(40) The connecting element 12 seems somewhat as if it is formed from a plate 20 (which forms the reinforcement ribs), on which the six tubular sleeves are integrally formed, the plate extending at the angle 2 in the plane spanned by the respective arms 6, 7 substantially in a direction transversely with respect to the extension direction L14, L15 of the connecting rods 14, 15. The plate 20, in this case, is substantially in the form of a circle segment.
(41)
(42) In the exemplary embodiment shown in
(43)
(44) A table element 60, 60a, 60b, in the present exemplary embodiment, has a length 160 of 400 mm, measured along the longitudinal axis L60 and consequently in a direction transversely with respect to the longitudinal axis L14 of the connecting rod L14, or rather with respect to the longitudinal axis of the longitudinal rod L54. The width b60 of a table element 60, in this case, in the present exemplary embodiment, is approximately 70 mm, measured transversely with respect to the longitudinal axis L60 of the table element along the third or rather fourth side face 63, 64. The thickness h60 of a table element or rather the height of the side faces 61, 62, 63, 64 here is approximately 75 mm.
(45) In the bottom view in
(46) As shown in
(47) The table top 11 projects above the longitudinal rods 54, 55 in a direction along the longitudinal axis L60 of a table element 60, which is arranged transversely with respect to the longitudinal axis L54 of the longitudinal rods 54, 55. The table top 11 equally also projects above a plane which is spanned by the four feet 44 of the frame 1a on the support 10.
(48) In the exemplary embodiment shown, the table elements 60, 60a, 60b are interconnected by an elastic connecting cord 77, as shown in
(49) When leaving each table element 60b, the elastic cord 77 passes through the passage opening 75 of the first spacer 67 in the first side face 61, crosses the space 69, is then guided through the first hole 73 in the second side face 62 of the first adjacent table element 60, then along the underside of the base surface 70, and once again through the passage opening 75 of the first spacer of the first adjacent table element 60, etc. In the transition to the frontmost table element 60a, the elastic connecting cord 77 leaves the passage opening 75 of the first spacer 67 in the first side face 61 of the table element 60 which is arranged adjacent the frontmost table element 60a, passes through the space 69 and then passes through the passage opening 76 of the second spacer 68 to the inside surface 61a of the first side face 61 of the frontmost table element 60a. Here, therefore, two first side faces 61 are located opposite one another as the frontmost table element 60a has been rotated by 180 degrees in order to avoid spacers protruding on the front outside surface beyond the table plate. Consequently, all the table elements 60, 60b, which are realized in an identical manner, have this same orientation, with the exception of the frontmost table element 60a, which has the opposite orientation. As a result of rotating the frontmost table element 60a about 180 degrees, in each case a first spacer 67 comes to rest opposite a second spacer 68. The first spacer 67 comprises a smaller outside diameter d67 than the outside diameter of the second spacer 68, and, in this case, is only marginally smaller than the inside diameter d68 of the second spacer 68, which enables a releasable or even loose plug-in connection between the first spacer 67 and the second spacer 68. When tightening the front two table elements 60, 60a elastically or rather laying them next to each other, on account of the smaller outside diameter d67 of the first spacer 67, the first spacer 67 of the adjacent table element 60 next to the frontmost table element 60a can then be inserted into the second spacer 68 of the frontmost table element 60a. This prevents the frontmost table element 60a being at a double spacing, which would be produced from the sum of the length 167 of the first spacer 67 and the length 168 of the second spacer 68, from the next adjacent table element 60 in the adjoining space 69, the two lengths 167, 168 being identical, and in the present exemplary embodiment, being approximately 4 mm. The table elements 60 arranged between the frontmost table element 60a and the rearmost table element 60b consequently abut against one another, whilst a plug-in connection by means of the respective spacers 67, 68 is produced between the frontmost table element 60a and the next adjacent table element 60. As an alternative to this, instead of the frontmost table element 60a, the rearmost table element 60b could also be arranged in a rotated manner and the plug-in connection would then be between the spacers 67, 68 of the rearmost table element 60b and the spacers 67, 68 of the table element 60 adjacent the rearmost table element 60b.
(50) After putting together the foldable frame 1a and unfolding or rather undoing the table elements 60, 60a, 60b forming the table top 11, the frontmost table element 60a and the rearmost table element 60b are stretched over the front and rear ends of the frame 1a or rather over the four coupling elements 50, 51, 52, 53, which bestows a certain inherent tension and stability on the table top 11. In this case, the tensioning of the elastic connecting cord 77 is adjusted in such a manner that the table elements 60, 60a, 60b are arranged in a slightly tensioned manner on the frame, the frontmost table element 60a and the rearmost table element 60b being clamped on the coupling elements 50, 51, 52, 53 and the remaining table elements resting in each case with or without clamping on the first and the second longitudinal rods 54, 55.
