A retractable column structure includes a metal outer tubular member, a retaining bracket, and an inner tubular member. The outer tubular member includes a wall having outer, inner and end surfaces. The outer tubular member includes slots extending from the end surface to the inner surface. A rear end of each slot includes a hook protruding out of the inner surface. The retaining bracket includes a frame member abutted against the wall and locking hooks inserted into the inner surface and locked onto each corresponding hook. The inner tubular member moveably penetrates into the retaining bracket disposed between the tubular members and is concealed inside the outer tubular member. Accordingly, excellent support of inner and outer tubular members can be achieved for stable sliding therebetween.

A collapsible measuring and cutting craft table enables cutting, measuring, and stowing fabric and craft materials from a foldable, height-adjustable, and mobile work surface. The craft table comprises a large, flat work surface having a center panel and two hingedly attached drop leaf panels that fold down for storage. Center support members support the center panel in a horizontal position at the desired working height. Two center support members supports the center panel of the work surface. The outer support members pivot outwardly to a support position to support the drop leaf panels. The outer support members pivot inwardly to a collapsed position to fold the drop leaf panels down perpendicularly relative to the center panel. The center support members telescopically adjust in length to height adjust the work surface. The support members terminates at wheels for mobility. Meshed baskets slide along rails that run between the center support members.

A collapsible, adjustable height table with a compact folded configuration and a range limiter to secure selected table heights.

A travel bag assembly that utilizes a bag construct with a top surface. A retractable pull handle is provided. A depression is formed in the top surface of the bag construct. A support platform is provided that either directly fits into the depression or can be folded to fit in the depression. The support platform is connected to the bag construct by at least one adjustable shaft. The adjustable shaft enables the support platform to be selectively adjusted in elevation throughout a range above top surface of the bag construct without effecting the retractable pull handle.

A height-adjustable device has synchronously height-adjustable lifting devices each having a standing and lifting element, which are height-adjustable relative thereto. The height adjustment is configured to be carried out via pulling elements, formed by redirection devices, to raise the lifting element relative to the standing element. Each pulling element is secured in a non-positive or positive locking manner to lifting devices, and each are configured such that a lengthening in the region of the first lifting device brings about a synchronous shortening in the region of the second lifting device. Each pulling element is constructed to raise only the one lifting element relative to the standing element. The height-adjustable device has a locking device that locks the pulling elements by a non-positive or positive locking engagement on the corresponding one of the pulling elements. The locking device is constructed to synchronise the movement of the pulling elements.

A table with a stabilizing system is disclosed. The table has a primary shaft having a bottom portion, a lower portion, and an upper portion, wherein the primary shaft has a cut-out at a bottom portion, a locking hole at a lower portion, and a stabilization mounting hole at the upper portion, a secondary shaft inserted into the primary shaft and when inserted, movably affixed to the primary shaft, wherein the secondary shaft has a bottom portion, a lower portion, and an upper portion, and wherein the secondary shaft a locking hole at the lower portion, and a stabilization mounting hole at the upper portion, a pivot positioned through the primary shaft stabilization mounting hole and the secondary shaft mounting hole to movably affix the secondary shaft to the primary shaft about a single point of movement, a lock positioned through the primary shaft locking hole and the secondary shaft locking hole, wherein the lock fastens the secondary shaft to the primary shaft.
