Multi-Size Folding Table with Stable Structure

This application claims priority to Chinese patent application number 202420853084.2, filed on Apr. 23, 2024. Chinese patent application number 202420853084.2 is incorporated herein by reference.

The present disclosure relates to the field of furniture, and specifically relates to a multi-size folding table with a stable structure.

Existing foldable tables with adjustable dimensions typically employ a middle table board pivotally connected to one or more side table boards. A stopper element is often used to abut both the middle table board and the one or more side table boards to secure the one or more side table boards in its unfolded position. The supporting legs are either fixed to or hinged with the middle table board.

When a force is applied to the one or more side table boards, a fulcrum of the force is a hinge point between the middle table board and the one or more side table boards. This configuration creates a long lever arm, resulting in deformation risks for the one or more side table boards, the hinge point with the middle table board, and the stopper element. Consequently, the one or more side table boards are insufficiently stabilized, and the structural components exhibit reduced durability.

To address these issues, practitioners in the art may consider attaching the supporting legs directly to the one or more side table boards. However, such an arrangement would either prevent the one or more side table boards from folding or render the table non-functional (e.g., unable to serve as a stable surface) when the one or more side table boards are folded.

The technical problem to be solved by the present disclosure is to provide a multi-size folding table with a stable structure.

In order to solve the above technical problems, the present disclosure provides the multi-size folding table with the stable structure comprising a table board and four table leg assemblies. The table board comprises a middle table board and two side table boards. Two ends of the middle table board in a length direction of the table board are respectively pivotally connected to the two side table boards, and the two side table boards are configured to be rotated to achieve unfolding and folding of the two side table boards.

A bottom surface of the table board is correspondingly disposed with guiding members, and the guiding members are respectively connected to the four table leg assemblies. The four table leg assemblies are configured to reciprocate along the length direction of the table board due to restriction of the guiding members.

Each of the four table leg assemblies comprises a supporting leg for supporting the table board. When the two side table boards are in an unfolded position, the supporting legs are slid to be located below the two side table boards. When the two side table boards are in a folded position, the supporting legs are slid to be located below the middle table board.

In some possible implementations, each of the four table leg assemblies comprises a side supporting member and a sliding rod. An end portion of the supporting leg and an end portion of the side supporting member are respectively pivotally connected to the sliding rod, and the side supporting member comprises a sliding groove extending along a length direction of the side supporting member. The supporting leg correspondingly comprises a position-limiting sliding block, and the position-limiting sliding block is disposed in the sliding groove and is configured to be relatively displaced along the length direction of the side supporting member to achieve unfolding or folding of the supporting leg.

In some possible implementations, each of the guiding members comprises at least one guiding tube extending along the length direction of the table board, and the sliding rod is sleeved with at least one of the at least one guiding tube. The four table leg assemblies are configured to be slid relatively in the length direction of the table board through a cooperation between the sliding rod and the at least one guiding tube.

In some possible implementations, one end of each of the guiding members away from a middle of the table board is disposed with a position-stopping member, and a distance between the position-stopping member and the at least one guiding tube adjacent to the position-stopping member is less than a length of the sliding rod. When the four table leg assemblies are slid to a farthest position along a direction away from the middle table board, the sliding rod abuts the position-stopping member.

In some possible implementations, the position-stopping member is disposed on a bottom surface of a corresponding one of the two side table boards.

In some possible implementations, one end of the sliding rod away from the middle of the table board is a pivoting end, and the supporting leg and the side supporting member are pivotally connected to the pivoting end. The at least one guiding tube is disposed on a bottom surface of the middle table board, and the pivoting end is located between the position-stopping member and the at least one guiding tube adjacent to the position-stopping member.

In some possible implementations, the supporting legs on two table leg assemblies of the four table leg assemblies arranged on a same side of the table board and spaced apart in a width direction of the table board are connected by a connecting rod, and the connecting rod and the supporting legs on the two table leg assemblies connected to the connecting rod form an H-shaped supporting leg.

In some possible implementations, a side of each of the two side table boards away from the middle table board comprises a table leg buckling groove. When the two side table boards are rotated inwardly to abut the H-shaped supporting legs, the H-shaped supporting legs are buckled to the table leg buckling grooves.

In some possible implementations, a length of each of the two side table boards is half a length of the middle table board.

In some possible implementations, the sliding rod and the at least one guiding tube sleeved on the sliding rod have an interference fit.

Compared with the existing techniques, the technical solution has the following advantages.

The present disclosure provides the multi-size folding table with the stable structure having the four table leg assemblies configured to slide along the length direction of the table board. When the two side table boards are unfolded, the four table leg assemblies can be slid to correspond to the bottom surface of the two side table boards. When the two side table boards are folded, the four table leg assemblies can be slid to correspond to the bottom surface of the middle table board. This technical solution mitigates influence of forces applied to the two side table boards and the two pivoting points with the middle table board, thereby enhancing structural stability and durability.

In some preferred implementations, when the four table leg assemblies are located below the two side table boards, the sliding rods simultaneously abut the two side table boards and the middle table board. The sliding rods, the supporting legs, and two sets of the two pivoting points connecting the two side table boards to the middle table boards cooperate to securely lock the two side table boards in the unfolded position.

It should be noted that when an element is described as “fixedly connected to” another element, it may be directly attached to the other element or intervening elements may be present. When an element is referred to as “connected to” another element, it may be directly connected or indirectly connected through intervening elements. In the present disclosure, directional or positional terms such as “upper,” “lower,” “bottom,” “rear,” “side,” “length direction,” and “width direction” are based on orientations or positional relationships shown in the accompanying drawings. These terms are used solely to simplify description and do not imply or require that the referenced device or component must adopt a specific orientation or configuration. Therefore, such terms should not be construed as limiting the scope of the present disclosure. For example, while the “length direction” and “width direction” are mutually perpendicular, the dimension of a table board along its “length direction” may be greater than, equal to, or less than its dimension along the “width direction.”

In this specification, the term “unfolded” for two side table boards refers to a state where upper surfaces of the two side table boards lie coplanar with an upper surface of a middle table board. Conversely, the term “folded” describes a position where the two side table boards are rotated inwardly (i.e., toward a bottom surface of the middle table board) about two sets of two pivoting points with the middle table board by 0-180° (excluding 0°) relative to its unfolded position. When the two side table boards are rotated by 180°, the two side table boards overlap completely with the middle table board, thereby minimizing a storage space required for the folding table in its non-use state. The term “bottom surface” of a table board, the middle table board, or the two side table boards refers to a downward-facing surface when the multi-size folding table is upright and the two side table boards are in their unfolded position.

The four table leg assemblies are configured to slide between a “closest position” and a “farthest position.” The “farthest position” is defined as a maximum distance a sliding rod can move a supporting leg and a side supporting member away from the middle table board, and vice versa.

The technical solutions of this application are described below in detail with reference to the accompanying drawings. It is evident that the described embodiments represent only one implementation of this multi-size folding table. All other embodiments derived by persons of ordinary skill in the art based on the following examples without creative effort shall fall within the protection scope of this application.

Referring toto, a multi-size folding table comprises a table boardand four table leg assemblies. Referring to, each of the four table leg assembliescomprises a supporting leg, a side supporting member, and a sliding rod, and an end portion of the supporting legand an end portion of the side supporting memberare respectively pivotally connected to the sliding rod. The side supporting membercomprises a sliding grooveextending along a length direction of the side supporting member. The supporting legcomprises a position-limiting sliding block, and the position-limiting sliding blockis buckled to the sliding grooveand is configured to be relatively displaced along the length direction of the side supporting memberto achieve unfolding or folding of a corresponding one of the four table leg assemblies.

The table boardcomprises a middle table boardand two side table boardspivotally connected to the middle table board. Specifically, each of the two side table boardsis pivotally connected to the middle table boardthrough two pivoting points. The two pivoting pointsare arranged on a lower side of the middle table boardand a lower side of a corresponding one of the side table boards. When the two side table boardsare in an unfolded position, as shown inand, a side of each of the two side table boardsabuts sides of the middle table board, which inhibits the two side table boardsfrom further rotating upward when in the unfolded position. The two side table boardscan be rotated inwardly by 0-180° with pivoting axes between the middle table boardand the two side table boardsas rotation axes. By unfolding or folding the two side table boardsrespectively, the table boardcan achieve three different usage size changes. In this embodiment, as shown in, a size of the middle table boardin a length direction of the table boardis twice a size of each of the two side table boards. When the two side table boardsare rotated inwardly by 180° from the unfolded position, the two side table boardsoverlap with the middle table board, and the four table leg assembliesare folded and stored between the two side table boardsand the middle table board.

Four guiding members are symmetrically disposed on a bottom surface of the table board, and each of the four guiding members comprises a guiding tubedisposed on a bottom surface of the middle table boardalong the length direction of the table boardand a position-stopping memberdisposed on a bottom surface of a corresponding one of the two side table boards, and the position-stopping memberis disposed on an extension line of the guiding tube. A distance between the position-stopping memberand the guiding tubeadjacent to the position-stopping memberin each of the four guiding members is less than a length of the sliding rod.

The sliding rodis sleeved with at least one of the guiding tubes, and the four table leg assembliesslide relatively in the length direction of the table boardthrough a cooperation between the sliding rodsand the guiding tubes. As shown in, when the four table leg assembliesslide to a farthest position in a direction away from the middle table board, the sliding rodabuts the position-stopping member. Furthermore, an end of the sliding rodaway from a middle of the table boardis a pivoting end. The supporting legand the sliding rodare pivotally connected at the pivoting end, and the pivoting endis located between the position-stopping memberand the guiding tubeadjacent to the position-stopping member. When the four table leg assembliesslide to a closest position in a direction close to the middle table board, as shown in, the side supporting memberabuts the guiding tubeadjacent to the position-stopping member. In addition, the sliding rodand the guiding tubesleeved on the sliding rodhave an interference fit, so that during sliding of the sliding rod, the four table leg assembliescan be maintained at any position between the closest position and farthest position by being tightly sleeved with the guiding tubes.

The two side table boardscan be in the unfolded position (and). The four table leg assembliescan be slid by the user to enable the four table leg assembliesto be at least partially located below the two side table boards. At this time, the sliding rodsabut the two side table boardsand the middle table boardat the same time, so that the sliding rodshave a function of fixing the two side table boardsin the unfolded position. At the same time, since the supporting legsare arranged below the two side table boardsdue to driving of the sliding rods, distances between edges of the two side table boardsaway from the middle table boardand the supporting legsare reduced. When the edges of the two side table boardsaway from the middle table boardare pressed, the two side table boardsare less likely to deform, and a pivoting connection between the two side table boardsand the middle table boardis more stable.

Furthermore, in this embodiment, the supporting legson two table leg assembliesof the four table leg assembliesarranged on a same side along a width direction of the table boardare connected by a connecting rod, and the connecting rodand the supporting legson the two table leg assembliesconnected to the connecting rodform an H-shaped supporting leg. A side of each of the two side table boardsaway from the middle table boardcomprises a table leg buckling groove. As shown in, when the two side table boardsare rotated inwardly to abut the H-shaped supporting legs, the H-shaped supporting legsare buckled to the table leg buckling grooves.

In addition, a reinforcing ribis disposed on the bottom surface of the middle table boardalong the length direction of the table board.
