When the telescopic frame forms an expanded state, the support unit 1 or With the expansion unit, 3, as a support-carrier', the carrier can be a soft carrier or a hard 7 200938126 material, a soft material such as a mesh cloth such as a hammock, a mattress or a wrap (4), hard material Such as a table or a shelf In one case, the simplification of the movable cross-linking unit 2 makes the overall manufacturing assembly more convenient and convenient, and the implementation of the bearing-mattress 4 is described in more detail as follows: ❹ ❹ Each branch unit 1 is along the -X The telescopic direction of the shaft is parallel and juxtaposed. In this example, the 'supporting single S-b is-frame body' includes two vertical poles 11 and two connecting the upper poles 12 and the lower crossbar U of the upright rods u, so that the supporting units i is formed in a letter shape, a first abutting portion lu is formed near the end of the upright rod u near the mattress 4, and a first socket portion 112 is formed near the second end portion of the upright rod 11 near the supporting surface. Moreover, the upright rod 11 is of a non-retractable or retractable configuration. When the telescopic structure is in a retractable configuration, the first abutting portion U1 and the first socket portion 112 can be changed in relative distances, in the upper crossbar 12 and below. At least the same sides 120, 130 of the cross bar 13 are respectively provided with a sliding seat called a sliding seat 14 and a sliding seat 15' on the upper sliding seat 14 and the lower horizontal rail ο of the upper crossbar 12 Each of the opposite faces is provided with a sliding groove 145. In this case, each supporting single cymbal 1 on the two outermost sides has only the same side 12G, 13 (), and each sliding direction is convexly provided with a sliding seat, but at the two outermost sides Each supporting soap 70 1 ′ in the middle of the supporting unit , is provided on the two sides of the upper cross bar 12 and the lower cross bar 13 , and a sliding seat is respectively protruded in the same direction, that is, the other upper sliding seat 14 is opposite to the sliding seat. The upper sliding seat 4 and the lower sliding seat 15 are corresponding to each other on each side of the upper crossbar 12 and the lower crossbar 13, and at one of the top and bottom of the upright pole n are respectively provided with a pivoting seat 16, 17 The pivoting seats 16, 17 are also recessed with a shaft hole 167. 8 200938126 ❹ ❹ Each of the active cross-linking units 2 is at a corresponding end 2〇2, 21〇 of the first rod body 20 and the second rod body 21 pivotally connected to each other, and a vertical connecting rod is connected. The first connecting rod 22 and the second connecting rod 23, and the other corresponding ends 203, 211 are also respectively connected with a connecting rod, which is called a third connecting rod 24, a fourth connecting rod 25, and each movable cross-connecting unit 2, The top and bottom of the second connecting rod 23 are pivotally disposed at the top of the upright rod u of the supporting unit i and the shaft hole 167 of the bottom pivoting seat 16, 17 , and the top and bottom of the first connecting rod 22 are framed. The upper slide of the same support unit = = the slide groove U5 of the slide base 15 is pivoted to the other support unit with the top and bottom of the fourth link 25! , erect # u' top and bottom pivot seat! The (four) of the 6', 17' is arranged in the top and bottom of the third link 24 on the same other element i, the lower slide i 14, and the chute 45' of the lower seat 15' At the same time, by changing the angle between the first rod body 20 and the second rod body 21 of the movable unit 2 and the second rod body 21, the supporting single & i can be changed in cooperation with the figure, FIG. 3 and FIG. The distance from the support unit 1' in the X-axis direction is changed while the distance is changed. The top and bottom of the first link 22 are slidably adjusted at the chute 145 and the top and bottom of the third link 24 are slid. The groove 145 is arranged to be slip-adjusted to avoid seizing and being unable to expand and contract, thereby allowing the adjacent two materials to change relative positions along the telescopic direction. a plurality of expansion frame elements 3, each expansion unit 3 is pivotally connected to the selection unit iti and can change the relative angle with the selection unit i. In this example, the extension support unit 3 includes a link.
