According to the present invention, the deformable assembling rack 1 is provided with advantages of easy to be folded/unfolded and stored, capable of being configured to various assembling status, and suitable to be applied as a structural body for being used as a household furniture or a household metal tool.

As shown in FIG. 1 and FIG. 2, according to the deformable assembling rack 1 of the present invention, the two vertical posts 10 are respectively formed with a C-shaped cross section, one lateral surface of each of the two vertical posts 10 is formed with a concave slot 11, and the two vertical posts 10 are oppositely arranged with a means of opening ends of the two concave slots 11 facing each other. Inner surfaces of the concave slots 11 of the two vertical posts 10 are respectively formed with an inner wall surface 111, and lateral wall surfaces 112 connected to two sides of the inner wall surface 111.

As shown in FIG. 2 and FIG. 3, the connection rod sets 20 are arranged and connected between the two vertical posts 10, the connection rod sets 20 respectively has a first connection rod 21 and a second connection rod 22, wherein two ends of the first connection rod 21 and two ends of the second connection rod 22 are respectively formed with a first end 211, 221 and a second end 212, 222, the first ends 211, 221 of the first connection rod 21 and the second connection rod 22 are respectively pivoted in the concave slots 11 of the two vertical posts 10, the second ends 212, 222 of the first connection rod 21 and the second connection rod 22 are respectively formed with a pivotal part 23, and the first connection rod 21 and the second connection rod 22 are pivoted via the pivotal part 23.

Please refer from FIG. 3 to FIG. 5, according to this embodiment, bottom ends of the two vertical posts 10 are further provided with a retractable extending sleeve rod 15, so that the lengths of the two vertical posts 10 can be adjusted. When the deformable assembling rack 1 is in use, the two vertical posts 10 are in a parallel status and would not cross with each other, meanwhile the connection rod sets 20 connected between the two vertical posts 10 are in a linear status, and substantially perpendicular to the two vertical posts 10, thereby assembling a rack member in which each crossed corner formed with an angle of 90 degrees, and the first connection rods 21 and the second connection rods 22 of the connection rod sets 20 are able to be mutually bent and folded for allowing the two vertical posts 10 to be mutually displaced towards each other, thereby enabling the deformable assembling rack 1 to be folded. According to this embodiment, the deformable assembling rack 1 can be applied as stairs, an assembled scaffold or a cloth hanging rack.

As show in FIG. 3, when the deformable assembling rack 1 is unfolded for being in an operating status, the first connection rods 21 and the second connection rods 22 of the connection rod sets 20 are displaced to an unfolded location, when the first connection rod 21 and the second connection rod 22 are displaced to the unfolded location, the first connection rod 21 and the second connection rod 22 are perpendicular to the two vertical posts 10 and arranged to be in a linear status. In the above-mentioned status, end surfaces of the first ends 211, 221 of the first connection rod 21 and the second connection rod 22 are abutted against inner sides of the inner wall surfaces 111 of the two vertical posts 10, and ends surfaces of the second ends 212, 222 of the first connection rod 21 and the second connection rod 22 are mutually abutted against each other, so that after the first connection rod 21 and the second connection rod 22 are displaced to the unfolded location where first connection rod 21 and the second connection rod 22 are arranged in parallel, a latched status is formed and no displacement can be further generated, thereby enabling the first connection rod 21 and the second connection rod 22 to be positioned at the unfolded location.

As shown in FIG. 4, the first ends 211, 221 of the first connection rod 21 and the second connection rod 22 are pivoted on the two vertical posts 10 by utilizing rivets or bolt shafts 27, one lateral side of the first ends 211, 221 or the first connection rod 21 and the second connection rod 22 is respectively formed with an arc-shaped chamfer 24, the arc-shaped chamfer 24 is coaxially arranged with the center of the bolt shaft 27 or the rivet which is utilized for connecting the first ends 211, 221 to the vertical post 10, thus the first connection rod 21 and the second connection rod 22 are able to generate displacing motions with the arc-shaped chamfer 24 being served as a center, and when the first connection rod 21 and the second connection rod 22 are displaced towards the direction of the arc-shaped chamfer 24, the first ends 211, 221 of the first connection rod 21 and the second connection rod 22 are prevented from generating an interfering action with the inner wall surface 111 of the vertical post 10. When the first connection rod 21 and the second connection rod 22 are displaced towards the two vertical posts 10, the interval between the two vertical posts 10 is gradually reduced.

As shown in FIG. 5, when the first connection rod 21 and the second connection rod 22 are displaced towards the direction of the two vertical posts 10, the first connection rod 21 and the second connection rod 22 would eventually be located at a folded location, when the first connection rod 21 and the second connection rod 22 are displaced to the folded location, the first connection rod 21 and the second connection rod 22 are aligned with the two vertical posts 10, and the first connection rod 21 and the second connection rod 22 are also aligned to be adjacent to each other.
