Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

One embodiment of a foldable multi-layer shelf is shown in figures 1 and 2. The multilayer shelf comprises left and right side vertical frames 1 and 2 and three

layer frames

3, 4 and 5. In the illustrated embodiment, each of the shelves and the side stands is a frame structure formed of a rod member, but the present invention is not limited thereto, and each of the shelves may be formed of a plate material, for example.

The two side stands 1, 2 are hinged and can rotate relatively around the hinge axis in the horizontal direction. Each layer frame is hinged with the unilateral vertical frame. Specifically, the uppermost shelf 3 is hingedly connected to the right-hand side stand 2, and the lower two

shelves

4, 5 are hingedly connected to the left-hand side stand 1. Each shelf can be turned up and down about its hinge axis. The free end of the uppermost shelf 3 rests on the left side stile 1 which is not in hinged relationship to the shelf. The free ends of the lower two

shelves

4, 5 rest on the right side uprights 2 which are not in hinged relationship with the two shelves.

A positioning piece 6 is fixed on the left vertical frame 1 supported by the free end of the uppermost layer frame 3. The positioning piece 6 connects the uppermost shelf 3 and the left-side vertical shelf 1 in the horizontal direction, but does not prevent the uppermost shelf 3 from turning upwards. When the uppermost layer frame 3 and the left side vertical frame 1 are connected together by the positioning piece 6, the two side vertical frames 1 and 2 are connected together by the uppermost layer frame 3 and can not rotate relatively.

Referring to fig. 2 and 3, as a preferred embodiment of the positioning member 6, the positioning member 6 is fixed to a stand on which the free end of the shelf rests, specifically, to the left-side stand 1. The positioning piece 6 is provided with a slot 7 with an upward notch, and the frame of the shelf 3 is inserted into the slot 7 from top to bottom, so that the connection between the shelf 3 and the left vertical frame 1 in the horizontal direction is formed, and the shelf 3 cannot be prevented from being turned upwards.

It should be noted that, as a variant, the positioning element 6 can also be fixed to the free end of the shelf 3. For example, the positioning member 6 shown in the figure is turned up and down and then welded and fixed to the free end of the shelf 3, the notch of the slot of the positioning member faces downward, the fixing piece corresponding to the slot is welded to the left-side vertical frame 1, and when the shelf 3 is turned over to a horizontal angle from top to bottom, the fixing piece is inserted into the slot, so that the connection between the shelf 3 and the left-side vertical frame 1 in the horizontal direction is also formed, and the shelf is not prevented from turning over upwards.

Preferably, the positioning element is also the load-bearing element of the layer shelf to which it is connected. In particular, the positioning element 6 fixed to the left-hand stand 1 is at the same time a bearing element for supporting the layer shelf 3. It should be noted that as a derivative, a bearing member, such as a pin, for supporting the layer 3 may be additionally fixed to the stand 1.

As the best mode, all the shelves are divided into an upper group and a lower group, and the two groups of shelves are respectively hinged with the vertical shelves 1 and 2 on the two sides. In particular, the uppermost shelf 3 forms the upper set of shelves, which is connected in an articulated manner to the right-hand vertical shelf 2, and the other two

shelves

4, 5 form the lower set of shelves, which two

shelves

4, 5 are connected in an articulated manner to the left-hand vertical shelf 1.

The layer frames belonging to the lower group are fixed with buckles for preventing the layer frames of the lower group from turning up and down, and the buckles are used as bearing parts for bearing the layer frames of the lower group. Specifically, as shown in fig. 1 and 2, the clip 8 is fixed to the layer frame 4, and the clip 8 serves as a bearing member for supporting the layer frame 4.

As shown in fig. 2, the buckle 8 is provided with a notch 9, and the notch 9 faces the stand hinged by the upper set of shelves, specifically the right stand 2, so that the buckle 8 does not prevent the right stand 2 from rotating in the horizontal direction. The two side stands 1 and 2 of the embodiment are both frame structures formed by rod pieces, and a cross rod 10 in the right side stand 2 can enter or exit from a notch 9 of the buckle along with the rotation of the right side stand 2. When the cross bar 10 of the right side stand 2 enters the notch 9 of the buckle, as shown in fig. 1, the buckle 8 supports the gravity of the shelf 4 and prevents the shelf 4 from turning up and down. If the uprights are not welded together by bars, for example, they may be formed by a vertical plate, a projection which enters and exits the opening of the catch may be fixed to the plate, and the weight of the shelves may be supported by the projection.

As a derivative structure, the buckle 8 may be fixed to a stand frame hinged to the upper set of the stand frames, specifically, the right-side stand frame 2, and the notch of the buckle may be directed toward the stand frame 4, so that the free end of the stand frame 4 may enter or exit the notch of the buckle as the right-side stand frame 2 rotates.

In a preferred embodiment, the two

shelves

4 and 5 of the lower set are hinged to the same link 11 to form a linkage. The weight of the two

shelves

4, 5 is supported simultaneously by the buckle 8. It should be noted that the lower set of shelves is not limited to two, and there may be only one shelf, or there may be more shelves. No matter whether a plurality of shelves of lower part a set have or not to constitute the linkage relation, can be for each shelf of lower part a set assembles a buckle 8.

When the folding shelf is folded, the uppermost shelf 3 is turned upwards, then the two side vertical shelves 1 and 2 are rotated like the hinge is opened until the two side vertical shelves 1 and 2 are attached together back to back, as shown in figure 4, and thus the folding of the multilayer shelf is completed. After being folded, the uppermost layer frame 3 is turned downwards to be attached to the right side vertical frame 2, and the lower two

layer frames

4 and 5 are turned upwards to be attached to the left side vertical frame 1.

It should be noted that the upper set of shelves is not limited to one, and there may be two or more shelves. Each layer frame of the upper group can be hinged with the same connecting rod to form linkage relation. If a plurality of shelves are arranged in a ganged relationship, a single locating element may be provided for only one of the shelves as described above. However, whether or not the shelves of the upper set are linked, each shelf of the upper set may be provided with a positioning member as described above.

It should be noted that as a simplified example, the shelves may not be grouped, all shelves being hingedly connected to the same side stand, wherein one or each shelf may be provided with a positioning element as described above.

As a preferred embodiment, referring to fig. 1, the lowermost shelf 5 is connected to support feet 12 which are supported on the ground. Therefore, the whole shelf is more stable. The connection of the supporting feet 12 to the layer 5 can be, but is not limited to, a screw connection or a rivet connection. The embodiment shown in fig. 1 is riveted, and the foot 12 can be rotated approximately 90 degrees as shown in fig. 2 to collapse the foot 12 when folded.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
