Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically to a foldable shelving. Background Technology

[0002] During the turnover of goods, shelves are usually set up with multiple shelves to accommodate more goods and improve turnover efficiency. In order to make these shelves easy to store and store when not in use and reduce space occupation, some folding shelves have appeared on the market. When the shelves are not needed, they can be folded and stored.

[0003] Among them, a folding shelf with patent number 202020565997.6 is an early inventive concept of the applicant. This folding shelf includes a front frame, a rear frame, several shelves, and a folding support. The shelves are positioned between the front and rear frames, and the folding support, composed of upper and lower connecting rods, enables switching between folding and unfolding. During folding, the upper and lower connecting rods gradually merge in a V-shape; conversely, during unfolding, they gradually unfold in a V-shape. However, because the hinge points of the upper and lower connecting rods are suspended and unsupported, with a high degree of freedom, the two folding support members may become asynchronous and asymmetrical during folding and unfolding, leading to deformation and jamming of the shelf.

[0004] Therefore, there is an urgent need to develop a brand new, easy-to-fold storage rack. Utility Model Content

[0005] To address the technical problems existing in the prior art, the purpose of this utility model is to provide a foldable storage rack with a simple structure and smooth and stable folding and unfolding process.

[0006] The objective of this utility model is achieved through the following technical solution: a foldable shelf, comprising a support mechanism and at least one shelf unit. The support mechanism includes a first bracket, a second bracket, and an auxiliary support rod. The first bracket includes at least two first folding rods, which are movably connected to opposite sides of the shelf unit via a first pivot. The second bracket includes at least two second folding rods, which are scissor-connected to the first folding rods via a second pivot. The auxiliary support rod includes at least two support rods, which are parallel to the first folding rods and movably connected to opposite sides of the shelf unit via a third pivot. The support rods intersect with the second folding rods, and each support rod has an axially extending through groove. The second folding rod is slidably connected to the through groove via a fourth pivot, allowing the support rod and the second folding rod to be scissor-connected. When the shelf unit is flipped, the third pivot rotates around the first pivot of the same shelf unit, and the fourth pivot moves relative to it within the through groove, causing the support rod and the first folding rod to move away from each other or merge, and causing the second folding rod and the first folding rod to form a certain angle or merge.

[0007] Furthermore, when the support rod is far from the first folding rod and the second folding rod forms a certain angle with the first folding rod, the shelf unit is horizontally unfolded with its opening facing upwards, and is in use; when the support rod is joined with the first folding rod and the second folding rod is joined with the first folding rod, the shelf unit is vertically set up and is in a folded state.

[0008] Furthermore, the auxiliary support rod includes at least one fastener, which includes a connecting part and a locking part. The connecting part connects the fastener to the support rod, and the locking part is detachably connected to the fourth rotating shaft, thereby locking the fourth rotating shaft in the through groove so that it does not move.

[0009] Specifically, the fastener is a strip-shaped rigid plate, one end of which is movably connected to the third rotating shaft. The end movably connected to the third rotating shaft is the connecting part. The other end of the fastener is suspended and equipped with a hook. The suspended end can rotate around the third rotating shaft, and the hook can be hung on the fourth rotating shaft.

[0010] Specifically, the connecting part is rotatably connected to the third pivot of the uppermost shelf unit.

[0011] Furthermore, the first bracket also includes at least two first connecting rods, which are respectively connected to the first folding rod above and below the shelf unit.

[0012] Specifically, the first link located below the shelf unit is connected to a caster wheel.

[0013] Furthermore, the second bracket also includes at least one second link, which is connected to the second folding rod below the shelf unit, and the second link is connected to a caster wheel.

[0014] Furthermore, an ear plate is provided on the first folding rod above the shelf unit, and a second pivot is provided on the ear plate. The second folding rod is scissor-connected to the first folding rod through the second pivot, so that the first folding rod and the second folding rod together form a V-shape.

[0015] Specifically, the shelf unit is a square-shaped container with an opening at the top, and there are three shelf units, with the three shelf units stacked at different intervals (top, middle, and bottom).

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] 1. By setting an auxiliary support rod, this utility model can not only provide stable support for the shelving unit, but also guide the fourth rotating shaft through the through groove of the support rod to fold or unfold the second bracket synchronously. This not only makes it convenient for users to simplify the folding and unfolding actions, but the through groove, as a fixed track, can also restrict the movement of the support mechanism during the folding or unfolding process, thereby folding or unfolding stably and avoiding deformation and jamming.

[0018] 2. This utility model also includes a locking device to fix the device in use and prevent accidental folding.

[0019] 3. This utility model is equipped with casters under the first and second supports for easy movement.

[0020] 4. The present invention provides a first connecting rod as a handle on the first bracket for easy gripping. Attached Figure Description

Any mechanisms or methods not elaborated in this utility model can be referred to in the prior art. The specific structures and features of this utility model are illustrated below by way of example and should not constitute any limitation on this utility model. Furthermore, any technical feature mentioned below (including implicit or disclosed features), as well as any technical feature directly shown or implied in the figures, can be arbitrarily combined or deleted among these technical features to form more other embodiments that may not be directly or indirectly mentioned in this utility model. The accompanying drawings show preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0027] like Figure 1-3 As shown, the foldable shelf of this embodiment includes a support mechanism and at least one shelf unit 10. The support mechanism is movably connected to the shelf unit 10, so that the shelf unit 10 can switch between unfolding and folding. The unfolded shelf unit 10 is in the use state, and the folded shelf unit 10 is in the non-use state, which is convenient for storage.

[0028] Specifically, the shelf unit 10 is a pocket-shaped container. In this embodiment, preferably, the shelf unit 10 is a square-shaped container with an opening at the top, and there are three shelf units 10. The three shelf units 10 are stacked at different intervals.

[0029] The support mechanism includes a first bracket, a second bracket, and an auxiliary support rod.

[0030] The first support includes two first folding rods 212 and two first connecting rods 216. The two first folding rods 212 are parallel to each other and movably connected to opposite sides of each shelf unit 10 via a first pivot 214. The shelf unit 10 can be flipped around the first pivot 214, which serves as the fulcrum for rotation. The two first connecting rods 216 are connected to the two first folding rods 212 above and below the three shelf units 10, respectively, forming a square frame shape. The first connecting rods 216 effectively enhance the support strength of the first support. The first connecting rods 216 located above the three shelf units 10 can be used as handles, and the first connecting rods 216 located below the three shelf units 10 are connected to casters 24.

[0031] The second support includes two second folding rods 223 and a second connecting rod 227. The two second folding rods 223 are parallel to each other and correspond to the two first folding rods 212 respectively. Ear plates 218 are provided on the first folding rods 212 above the three shelf units 10. A second pivot 225 is provided on the ear plates 218. The second folding rods 223 are scissor-shaped connected to the first folding rods 212 via the second pivot 225, so that the first folding rods 212 and the second folding rods 223 together form a V-shape. The second folding rods 223 can rotate relative to the first folding rods 212 around the second pivot 225, so that the second folding rods 223 and the first folding rods 212 form a certain angle or are joined together. The second connecting rod 227 connects to the second folding rods 223 below the three shelf units 10, forming a U-shaped frame. The second connecting rod 227 effectively enhances the support strength of the second support and is connected to casters 24.

[0032] The auxiliary support rod includes two support rods 234 and two fasteners 236.

[0033] Two support rods 234 correspond to two first folding rods 212 respectively and are parallel to each other. The support rods 234 are movably connected to opposite sides of each shelf unit 10 via a third pivot 238. When the shelf unit 10 is flipped, the third pivot 238 can rotate around the first pivot 214 of the same shelf unit 10, thereby causing the support rods 234 to move parallel to or away from their corresponding first folding rods 212. Two support rods 234 intersect with two second folding rods 223 respectively. The second folding rods 223 are provided with a fourth rotating shaft 239. The support rods 234 are provided with a through groove 2340 extending along the axial direction of the support rods 234. The fourth rotating shaft 239 is slidably connected to the through groove 2340. The support rods 234 are scissor-type movablely connected to the corresponding second folding rods 223 through the fourth rotating shaft 239. The fourth rotating shaft 239 can move within the stroke range of the through groove 2340. The support rods 234 can rotate relative to the second folding rods 223 around the fourth rotating shaft 239, so that the support rods 234 and the second folding rods 223 form a certain angle or merge.

[0034] Two fasteners 236 are correspondingly mounted on the two support rods 234. Each fastener 236 includes a connecting part 2361 and a locking part 2365. The connecting part 2361 connects the fastener 236 to the support rod 234, and the locking part 2365 is detachably connected to the fourth rotating shaft 239, thereby locking the fourth rotating shaft 239 within the through groove 2340 to prevent movement. In this preferred embodiment, the fastener 236 is a strip-shaped rigid plate, one end of which is movably connected to the third rotating shaft 238. Specifically, one end of the fastener 236 is rotatably connected to the third rotating shaft 238 of the uppermost shelf unit 10. The third rotating shaft 238 of the uppermost shelf unit 10 has more operating space, facilitating the rotation of the fastener 236. The end that is movably connected to the third rotating shaft 238 is the connecting part 2361 of the fastener 236. The other end of the fastener 236 is suspended and equipped with a hook. The suspended end can rotate around the third rotating shaft 238. The hook can be hung on the fourth rotating shaft 239 to limit the distance between the fourth rotating shaft 239 and the third rotating shaft 238, thereby locking the fourth rotating shaft 239 in the through groove 2340 and preventing it from moving.

[0035] The shelf in this embodiment has a use state and a non-use state. In the use state, the shelf unit 10 is unfolded and laid flat, and items can be placed in its storage space. In the non-use state, the shelf unit 10 is folded and erected, and the shelf is easy to store.

[0036] In this embodiment, the shelf is used in a stacked configuration of three shelf units 10, arranged in a top-middle-bottom layer. The first and second supports of the support mechanism are spread out in an A-shape to support the three shelf units 10 when laid flat. The auxiliary support rod is parallel to the first support and spread out in an X-shape with the second support. The hook of the fastener 236 is hooked onto the fourth pivot 239 of the second support, limiting the distance between the fourth pivot 239 and the third pivot 238, thereby locking the fourth pivot 239 within the through groove 2340 and preventing it from moving. This, in turn, locks the support mechanism in place to maintain the shelf's usability.

[0037] When the shelf changes from its active state to its inactive state, the locking relationship between the hook of the fastener 236 and the fourth pivot 239 is first released. Then, the shelf unit 10 is flipped upwards, causing the third pivot 238 to rotate around the first pivot 214 within the same shelf unit 10. This causes the support rod 234 to move parallel towards its corresponding first bracket. Simultaneously, through the sliding relationship of the fourth pivot 239 within the through groove 2340, the second bracket is pulled by the support rod 234 towards the first bracket. During this process, the flipped shelf unit 10 pulls the support rod 234 upwards, and correspondingly, the fourth pivot 239 moves downwards within the through groove 2340 of the support rod 234. Finally, the first bracket, the second bracket, and the auxiliary support rod are folded together, and the shelf unit 10 is folded upright, forming the inactive state of the shelf in this embodiment.

[0038] Conversely, when the shelf transitions from a non-use state to a use state, the shelf unit 10 is flipped downwards, causing the third pivot 238 to rotate around the first pivot 214 within the same shelf unit 10. This causes the combined support rod 234 to move parallel away from its corresponding first bracket. Simultaneously, through the sliding relationship of the fourth pivot 239 within the through groove 2340, the second bracket is pulled away from the first bracket by the support rod 234. During this process, the flipped shelf unit 10 causes the support rod 234 to move downwards, and correspondingly, the fourth pivot 239 moves upwards within the through groove 2340 of the support rod 234. Finally, the shelf unit 10 unfolds and lies flat, with the first and second brackets spread out in a V-shape, and the auxiliary support rod parallel to the first bracket and spread out with the second bracket in an X-shape. The rotating fastener 236 hooks its hook onto the fourth pivot 239, switching the shelf to the use state of this embodiment.

[0039] In the above embodiment, the caster wheels are connected to the first link and the second link. In other embodiments, the first bracket does not have a first link located below the shelf, and the second bracket does not have a second link located below the shelf; the caster wheels may be located at the lower ends of the first folding rod and the second folding rod.

[0040] In the above embodiment, one side panel of the shelving unit has an opening; in other embodiments, the side wall of the shelving unit does not have an opening, such as... Figure 4 As shown.

[0041] Compared to existing technologies, the foldable shelf in this embodiment features an auxiliary support rod. During unfolding and folding, the support rod's slot guides the fourth pivot of the second bracket, ensuring stable and smooth movement. The fastener design further ensures the shelf remains stable and is less prone to accidental folding due to external forces.

[0042] The above embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. For those skilled in the art, it will be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
