Suitable for restaurant dining tables, coffee tables, etc., the under-table rotating tray consists of three parts: a tray, a round tube support, and a cover.

[0003] Common ways to increase desktop storage space without changing the furniture's footprint include trolleys and pull-out drawers. Trolleys take up a lot of space, while pull-out drawers require opening to access items, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a hidden under-table rotating tray, which aims to solve the problem of inconvenience in taking out items in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hidden under-table rotating tray includes a mounting plate installed on the table, a fixed shaft extending in the vertical direction fixed below the mounting plate, a connecting member rotatably arranged relative to the fixed shaft, and a tray assembly fixedly connected to the connecting member, so that the tray assembly can rotate around the fixed shaft;

[0006] The pallet assembly includes a lower pallet fixedly connected to a connector, an intermediate pallet that moves up and down along the lower pallet, and an upper pallet that moves up and down along the intermediate pallet.

[0007] The lower-level tray is equipped with a lower-level lifting component, which drives the middle-level tray and the upper-level tray to move up and down; the middle-level tray is equipped with an upper-level lifting component, which drives the upper-level tray to move up and down, thereby adjusting the distance between the lower-level tray, the middle-level tray and the upper-level tray.

[0008] Preferably, the lower-level lifting assembly includes a lower-level fixing block fixed on the inner bottom wall of the lower-level tray, a lower-level driving component disposed on the lower-level fixing block, two sets of lower-level connecting rods spaced apart to the left and right and connected to the lower-level driving component, and a lower-level connecting rod hinged to the lower-level connecting rods.

[0009] The lower secondary connecting rod is hinged to the bottom of the intermediate tray;

[0010] A lower-level handle is fixed to the lower-level drive component, and the lower-level handle is located below the lower-level tray.

[0011] Preferably, the lower-level fixing block has a lower-level cavity;

[0012] The driving component includes a lower vertical rod that is rotatably disposed in the lower cavity and extends in the vertical direction, and a lower horizontal rod that is connected to the lower vertical rod and extends in the horizontal direction.

[0013] The lower vertical rod extends through the lower tray and is fixedly connected to the lower handle;

[0014] The left and right ends of the lower-level crossbar extend through the lower-level fixing block and are hinged to the next-level connecting rod.

[0015] Preferably, the upper lifting assembly includes an upper fixing block fixed on the inner bottom wall of the intermediate tray, an upper driving component disposed on the upper fixing block, two sets of upper first-level connecting rods spaced apart from each other and connected to the upper driving component, and an upper second-level connecting rod hinged to the upper first-level connecting rods.

[0016] The upper secondary connecting rod is hinged to the bottom of the upper tray;

[0017] An upper-level handle is fixed to the upper-level drive component, and the upper-level handle is located below the lower-level tray.

[0018] Preferably, the upper-level fixing block is provided with an upper-level cavity;

[0019] The upper-level driving component includes an upper-level telescopic sleeve rod that rotates within the upper-level cavity and extends in the vertical direction, and an upper-level crossbar that is pulsatorically connected to the upper-level telescopic sleeve rod and extends in the horizontal direction.

[0020] The upper telescopic sleeve extends through the middle tray and the lower tray and is fixedly connected to the upper handle;

[0021] The left and right ends of the upper crossbar extend through the upper fixing block and are hinged to the upper connecting rod.

[0022] Preferably, the top of the lower tray has an upward-facing lower limiting hole, and the middle tray has a plurality of lower insert rods arranged in a circumferential array and extending in the vertical direction, the lower insert rods being adapted to the lower limiting hole;

[0023] The top of the intermediate tray has an upward-facing upper-level limiting hole. Several upper-level insert rods are fixed on the upper-level tray in a circumferential array and extend in the vertical direction. The upper-level insert rods are adapted to the upper-level limiting hole.

[0024] Preferably, the connector includes a circular tube mounted on the mounting plate and extending in the vertical direction, and a crossbar fixedly connected between the circular tube and the lower tray;

[0025] The circular tube is sleeved on the fixed shaft.

[0026] The beneficial effects are: 1. The tray assembly is mounted on the table using a mounting plate and a fixed shaft. When needed, simply rotate the tray assembly, and it will slowly emerge from under the table, providing a convenient space for placing items. When not in use, the tray assembly can be rotated back under the table. In this way, the tray assembly cleverly achieves concealed storage. This not only improves the overall aesthetics of the table, making the desktop look cleaner and less cluttered, but also ensures that the tray assembly is stored under the table without affecting its normal use, thus increasing the table's practicality and allowing it to be more functional without sacrificing aesthetics and tidiness.

[0027] 2. Once the tray assembly rotates out, it can be rotated using the lower and upper handles. During this rotation, the intermediate and upper trays gradually rise from the lower tray. This allows items to be placed within the intermediate and lower trays. This design effectively increases the storage space, accommodating more items and significantly improving space utilization to meet the needs of storing more items. Attached Figure Description

[0036] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0037] like Figures 1-7 As shown, a hidden under-table rotating tray is mainly used so that when the tray assembly 2 is not in use, it can be rotated to the bottom of the table for hidden storage, which does not affect the use of the table and can also improve the aesthetics of the table. When needed, the tray assembly 2 can be rotated out from under the table and then used to place items.

[0038] In this embodiment, the structure and principle of the table are existing technologies and will not be described in detail here.

[0039] In this embodiment, the rotating tray includes a mounting plate 3 installed on a table, a fixed shaft 16 extending in the vertical direction fixed below the mounting plate 3, a connector 1 rotatably disposed relative to the fixed shaft 16, and a tray assembly 2 fixedly connected to the connector 1. When needed, the operator can manually rotate the tray assembly 2 to rotate the tray assembly 2 around the fixed shaft 16 from under the table for use.

[0040] Specifically, the fixed shaft 16 is mounted on the mounting plate 3 by bolts, and the connecting piece 1 is sleeved on the fixed shaft 16 so that the connecting piece 1 can rotate.

[0041] like Figures 1-5 As shown, the pallet assembly 2 includes a lower pallet 201 fixedly connected to the connector 1, an intermediate pallet 202 that moves up and down along the lower pallet 201, and an upper pallet 203 that moves up and down along the intermediate pallet 202. The lower pallet 201 is provided with a lower lifting assembly 4, which drives the intermediate pallet 202 and the upper pallet 203 to move up and down. After the lower lifting assembly 4 is activated, it can drive the intermediate pallet 202 and the upper pallet 203 to rise out of the lower pallet 201, so that the space between the intermediate pallet 202 and the lower pallet 201 is increased to facilitate the storage of items.

[0042] Specifically, the lower-level lifting assembly 4 includes a lower-level fixing block 401 fixed on the inner bottom wall of the lower-level tray 201, a lower-level driving component provided on the lower-level fixing block 401, two sets of lower-level connecting rods 402 spaced apart and connected to the lower-level driving component, and a lower-level connecting rod 403 hinged to the lower-level connecting rods 402; the lower-level connecting rod 403 is hinged to the bottom of the intermediate tray 202; a lower-level handle 6 is fixed on the lower-level driving component, and the lower-level handle 6 is located below the lower-level tray 201. When the lower-level crossbar 9 rotates, it can drive the lower-level connecting rod 402 to rotate. Since the lower-level connecting rod 402 is hinged to the lower-level connecting rod 403, it can drive the lower-level connecting rod 403 to rotate, so that the intermediate tray 202 rises out of the lower-level tray 201.

[0043] The lower-level fixing block 401 has a lower-level cavity 7; the driving component includes a lower-level vertical rod 8 that is rotatably disposed in the lower-level cavity 7 and extends in the vertical direction, and a lower-level horizontal rod 9 that is connected to the lower-level vertical rod 8 and extends in the horizontal direction. In this embodiment, a first bevel gear is fixed on the lower-level vertical rod 8, and a second bevel gear is fixed on the lower-level horizontal rod 9. The first bevel gear and the second bevel gear mesh with each other, so that when the lower-level vertical rod 8 rotates, it can drive the lower-level horizontal rod 9 to rotate. The lower-level vertical rod 8 passes through the lower-level tray 201 and is fixedly connected to the lower-level handle 6; the left and right ends of the lower-level horizontal rod 9 pass through the lower-level fixing block 401 and are hinged to the next-level connecting rod 402. When the lower-level handle 6 rotates, it can drive the lower-level vertical rod 8 to rotate.

[0044] like Figure 3 , Figure 6 and Figure 7 As shown, the intermediate tray 202 is equipped with an upper lifting component 5, which drives the upper tray 203 to move up and down, thereby adjusting the distance between the intermediate tray 202 and the upper tray 203.

[0045] Specifically, the upper lifting assembly 5 includes an upper fixing block 501 fixed on the inner bottom wall of the intermediate tray 202, an upper driving component provided on the upper fixing block 501, two sets of upper first-level connecting rods 502 spaced apart and connected to the upper driving component, and an upper second-level connecting rod 503 hinged to the upper first-level connecting rods 502; the upper second-level connecting rod 503 is hinged to the bottom of the upper tray 203; an upper handle 10 is fixed on the upper driving component, and the upper handle 10 is located below the lower tray 201. When the upper crossbar 13 rotates, it can drive the upper first-level connecting rod 502 to rotate. Since the upper first-level connecting rod 502 is hinged to the upper second-level connecting rod 503, it can drive the upper second-level connecting rod 503 to rotate, so that the upper tray 203 is lifted out of the intermediate tray 202, so that items can be placed in the space between the intermediate tray 202 and the upper tray 203.

[0046] The upper-level fixed block 501 has an upper-level cavity 11; the upper-level driving component includes an upper-level telescopic sleeve 12 that rotates within the upper-level cavity 11 and extends in the vertical direction, and an upper-level crossbar 13 that is pulsatorically connected to the upper-level telescopic sleeve 12 and extends in the horizontal direction. In this embodiment, the upper-level telescopic sleeve 12 is composed of several spline tube guide sliding sleeves. When the middle-level tray 202 moves up and down, it can drive the spline tubes to extend. The structure and principle of the spline tubes are existing technologies and will not be described in detail here. The upper telescopic sleeve 12 passes through the middle tray 202 and the lower tray 201 and is fixedly connected to the upper handle 10. In this embodiment, a third bevel gear is fixed on the uppermost spline tube, and a fourth bevel gear that meshes with the third bevel gear is fixed on the upper crossbar 13. When the spline tube rotates, it can drive the upper crossbar 13 to rotate. The left and right ends of the upper crossbar 13 pass through the upper fixing block 501 and are hinged to the upper connecting rod 502. When the upper handle 10 rotates, it can drive the spline tube to rotate.

[0047] like Figure 1 and Figure 3 When the intermediate tray 202 and the upper tray 203 are raised or lowered, they can be limited by the lower insertion rod 14 and the upper insertion rod 15 to prevent the intermediate tray 202 and the upper tray 203 from tilting during the raising or lowering process.

[0048] Specifically, the lower tray 201 has an upward-facing lower limiting hole at its top. The middle tray 202 has several lower insert rods 14 arranged in a circular array and extending in the vertical direction. The lower insert rods 14 are adapted to the lower limiting hole. When the middle tray 202 is raised or lowered, it can drive the lower insert rods 14 to move up and down along the lower limiting hole. The middle tray 202 has an upward-facing upper limiting hole at its top. The upper tray 203 has several upper insert rods 15 arranged in a circular array and extending in the vertical direction. The upper insert rods 15 are adapted to the upper limiting hole. When the upper tray 203 is raised or lowered, it can drive the upper insert rods 15 to move up and down along the upper limiting hole.

[0049] like Figures 1-3 As shown, the connector 1 includes a round tube 101 mounted on the mounting plate 3 and extending in the vertical direction, and a crossbar 102 fixedly connected between the round tube 101 and the lower tray 201 for connecting the lower tray 201. The round tube 101 is sleeved on the fixed shaft 16.

[0050] Working principle: When in use, tray assembly 2 can be rotated under the table for hidden storage when not in use, without affecting the use of the table and also improving the table's appearance.

[0051] When needed, the operator can manually rotate the tray assembly 2 to allow it to rotate out from under the table around the fixed axis 16 for use. If the storage space needs adjustment, the lower handle 6 is rotated. Rotating the lower handle 6 rotates the lower vertical bar 8, which in turn rotates the lower horizontal bar 9. Rotating the horizontal bar 9 then rotates the next-level connecting rod 402. Since the next-level connecting rod 402 is hinged to the next-level connecting rod 403, it rotates the next-level connecting rod 403, causing the intermediate tray 202 to rotate from the lower tray 201. The upper tray 203 is raised outwards to adjust the space between the lower tray 201 and the middle tray 202. Then, the upper handle 10 is rotated, which drives the upper crossbar 13 to rotate via the upper telescopic sleeve 12. When the upper crossbar 13 rotates, it can drive the upper first-level connecting rod 502 to rotate. Since the upper first-level connecting rod 502 is hinged to the upper second-level connecting rod 503, it can drive the upper second-level connecting rod 503 to rotate, so that the upper tray 203 is raised outwards from the middle tray 202, so that items can be placed in the space between the middle tray 202 and the upper tray 203, thus improving practicality.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
