Collapsible storage structure

Abstract

This invention provides a retractable storage structure with a synchronized window opening mechanism. The main structure includes a bottom frame, a top frame, two pivotable side panels that can be pivoted and folded, a back panel and a front frame that can be pivoted and extended, and a movable tray that can automatically open and close the window sash. This improves the problem of cumbersome opening and closing operation of traditional storage structures, optimizes the smoothness of users retrieving items, and reduces the space burden when not in use through its retractable and foldable feature.

Claims

1. A retractable storage structure, comprising: a bottom frame and a top frame located above the bottom frame, wherein the top frame is movable relative to the bottom frame between an unfolded position and a retracted position, and in the unfolded position forms a storage space between the two; two pivotable side panels, respectively disposed on both sides of the storage space, and pivotally folded between the top frame and the bottom frame, for being able to stand upright on both sides of the storage space in the unfolded position, and pivotally folded between the top frame and the bottom frame in the retracted position; and a back panel, which is pivotally foldable. A pivot is located at the rear of the top frame, allowing it to stand upright at the rear of the accommodating space and abut against the top and bottom frames when unfolded, and to pivot horizontally within the top frame when folded; a front frame is slidably pivotally mounted at the front of the top frame, allowing it to be upright and fixed to the front of the accommodating space when unfolded, and to pivot and slide horizontally within the top frame when folded; and a movable tray is slidably mounted on the bottom frame, allowing it to carry items that move back and forth relative to the accommodating space when unfolded. When the movable tray moves forward, it can pass through a window with a central cutout in the front frame, and is pivotally connected to two window sashes on both sides of the window via two connecting rods, so that the two window sashes can be opened or closed synchronously when the movable tray moves forward or backward.

2. The collapsible storage structure as described in claim 1, wherein the collapsible tray is further provided on the front side with a gripping portion that protrudes from the window to provide a grip.

3. The collapsible storage structure as described in claim 2, wherein the two ends of the two links are respectively pivotally connected to the bottom surface of the movable tray and the lower edge of each window sash.

4. The collapsible storage structure as described in claim 3, wherein the collapsible tray is connected to a guide groove extending in the front-rear direction of the bottom frame via at least one guide slider protruding from the bottom.

5. The collapsible storage structure as described in any one of claims 1 to 4, wherein each of the pivoting side panels includes an upper panel and a lower panel pivotally connected to each other on one side, the other side of the upper panel being pivotally connected to the top frame, and the other side of the lower panel being pivotally connected to the bottom frame.

6. The collapsible storage structure as described in claim 5, wherein each of the upper plates and each of the lower plates is provided with a positioning protrusion on its front side for engaging and fixing the front frame.

7. The collapsible storage structure as described in claim 6, wherein the back panel is pivotally mounted on the top side of the top frame and has at least one connecting portion on the bottom side for detachably connecting to one of the connecting portions at opposite positions of the bottom frame.

8. The collapsible storage structure as described in claim 7, wherein the front frame is slidably pivotally mounted on the top frame, and at least one positioning part is provided on each of the two sides and the bottom side for being detachably coupled or snapped to the positioning protrusions of each of the upper plates and each of the lower plates and one of the positioning parts of the bottom frame.

9. The collapsible storage structure as described in claim 8, wherein the bottom frame system can be further connected to a top frame of another accommodating space to form a collapsible storage structure in which a plurality of accommodating spaces are stacked and extended.
