Description

Technical Field

[0001] The invention relates to a folding table, in particular to a novel folding table. Background Art

[0002] Small-sized houses have a small area, and traditional tables take up more space. For this reason, folding tables came into being. Folding tables can be folded when not in use, which greatly reduces the space they occupy. This is especially important for urban apartments or small houses with limited living space. Folding tables can be easily stored in corners or cabinets to free up more space for other activities. At the same time, the lightness and mobility of folding tables allow them to be flexibly placed as needed. Whether it is for different activities at home or for outdoor camping, picnics and other occasions, folding tables can easily cope with and meet diverse usage needs. At the same time, existing folding tables come in a variety of styles, such as dining tables, office desks, workbenches, etc. Through simple folding and unfolding, their use can be quickly changed to meet different living and working needs.

[0003] However, the common household folding tables currently do not provide other functions when they are folded, and they also affect the appearance, and need to be stored in a storage space. When they are used, they need to be taken out of the storage space, which affects the user experience. Summary of the invention

[0004] The invention provides a novel folding table, which solves the problem in the prior art that the folding table in a folded state cannot provide other functions and affects the aesthetics of the space.

[0005] The above technical problems of the present invention are mainly solved by the following technical solutions: a new type of folding table, including a cabinet, a first table board, a second table board and supporting legs, the cabinet is composed of two vertical side panels, a cover plate and a plurality of connecting plates fixedly connecting the two side panels, a receiving cavity is formed inside the cabinet, the first table board is horizontally pivoted between the two side panels, the pivot axis is located on the upper side of the receiving cavity, a hinge is provided on the back side of the first table board away from the pivot axis, and the second table board is also fixedly connected to the hinge; the back side of the first table board is also rotatably connected to the hinge Two telescopic parts are connected, and the other ends of the two telescopic parts are rotatably connected to the side panels, and the telescopic parts are provided with length limit locks; a supporting plate is provided at the top of the supporting leg, and a plurality of positioning blocks are convexly provided on the top surface of the supporting plate, and positioning grooves corresponding to the positioning blocks are provided on the backs of the first table board and the second table board; when the first table board is turned outward to a horizontal state, the length limit lock can lock the telescopic part in this length state; when the second table board is turned outward to be horizontal with the first table board, the supporting plate on the supporting leg can abut against the bottom of the two table boards at the same time.

[0006] The vertical cabinet, the first table board, and the second table board in the present invention are pivotally connected to each other and can be turned over freely. The supporting legs and the telescopic parts can fix the two table boards in specific turning states, including: in the folded state, the second table board is turned inward so that the second table board fits against the back of the first table board, and then the first table board is turned downward to a vertical drooping state, the receiving cavity is completely covered by the first table board, the second table board is located in the receiving cavity, the supporting legs are also received in the receiving cavity, and the telescopic parts are in a retracted state. At this time, the present invention has a simple cabinet appearance as a whole, and its upper side can also be used to place objects; in the semi-expanded state, the first table board is turned over to a horizontal state, and the telescopic parts are in a semi-expanded state. The retractable part is in an extended state, and the length limit lock can lock the retractable part in this state to keep its length fixed, so that the two retractable parts can maintain the first table board in a horizontal state. The present invention in this state is suitable for use when there are not many people; in the fully expanded state, on the basis of the semi-expanded state, the second table board is also flipped up to a horizontal state, and the supporting legs are taken out, and the positioning blocks on the support plate are engaged with the positioning grooves on the backs of the two table boards. At this time, the supporting legs can simultaneously support the two table boards, and the two table boards are in an equal height state. The present invention in this state has the largest table top, and the load-bearing stability of the table top is also better.

[0007] Furthermore, the telescopic member includes a sleeve pivotally connected to the side panel and a telescopic rod pivotally connected to the first table board, and the telescopic rod is slidably inserted into the sleeve; the length limit lock is fixed on the sleeve, and a slot is provided on the telescopic rod. The length limit lock is composed of a first lock shell, a latch and a pull rod, and a first reset spring is also provided in the first lock shell to push the latch to move inside the sleeve; when the first table board is in a horizontal state, the slot is just opposite to the latch, and the first reset spring can push the latch into the slot, so that the telescopic member is locked. At the same time, the outer end of the pull rod extends to the outside of the first lock shell, and by pulling the pull rod in the opposite direction, the latch can be driven out of the slot, thereby releasing the locking state of the telescopic member. It should be noted that when pulling the pull rod, it is necessary to hold the first table board by hand to reduce the friction between the latch and the slot.

[0008] Furthermore, a first limit plate is provided inside the sleeve and near one end of the pivot connection, a second limit plate is provided on the telescopic rod, and a buffer spring is provided between the first limit plate and the second limit plate. When the first table top flips downward, the telescopic rod in the sleeve will shrink inward, so that the distance between the two limit plates is reduced. Because the first table top has a tendency to flip downward due to its own gravity, in order to avoid the accident of pinching the hand due to the first table top flipping too quickly, the present invention provides a buffer spring between the two limit plates to absorb part of the kinetic energy, thereby playing a role in hindering the first table top from flipping downward, which can effectively prevent the first table top from flipping too quickly. At the same time, it can also provide a certain lifting force when the first table top flips upward, which is more labor-saving to use. The normal length of the buffer spring does not necessarily have to be greater than or equal to the maximum distance between the two limit plates.

[0009] Furthermore, a table board limit lock is provided on the back of the first table board, and the table board limit lock is composed of a second lock shell, a sliding pin slidingly arranged in the second lock shell, and a second return spring that pushes the sliding pin to slide outward. The second lock shell also exposes a shift block fixedly connected to the sliding pin, and the front end of the sliding pin is arranged as an inclined surface. A lock hole is provided on the side wall of the second table board. When the second table board is flipped to fit the back of the first table board, the front end of the sliding pin can be extended into the lock hole to form a lock. The table board limit lock is used to fix the second table board in the folded state to prevent it from freely sagging in the semi-expanded state.

[0010] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The present invention can be folded to achieve a folded state, a semi-expanded state and a fully expanded state. In the folded state, the overall appearance of the present invention is a small cabinet shape, and it also has a certain function of placing items. It is suitable for placement against the wall and the appearance is not abrupt. Therefore, there is no need to find a separate place to store it, and the effect of folding and unfolding in situ is achieved, which is more convenient to use; 2. The folding or unfolding action of the present invention is streamlined, the structure in the expanded state is stable, and the opening and closing is convenient and quick.

[0020] Example 1: See Figure 1 , Figure 2 and Figure 3 A novel folding table comprises a cabinet 10, a first table board 20, a second table board 30 and a supporting leg 40. The cabinet is composed of two vertical side boards 50, a cover board 60 and three connecting boards 70 fixedly connected to the two side boards. A receiving cavity 11 is formed inside the cabinet. The first table board is horizontally pivoted between the two side boards. The pivot axis is located on the upper side of the receiving cavity. A hinge 21 is provided on the back of the first table board away from the pivot axis. The second table board is also fixedly connected to the hinge. Two telescopic members 80 are also rotatably connected to the back of the first table board. The other ends of the two telescopic members are rotatably connected to the side boards. The telescopic members are provided with length limit locks 90. Figure 6 and Figure 7 A supporting plate 41 is provided at the top of the supporting leg, and four positioning blocks 42 are convexly provided on the top surface of the supporting plate. Positioning grooves 43 corresponding to the positioning blocks are provided on the backs of the first table board and the second table board; when the first table board is turned outward to a horizontal state, the length limit lock can lock the telescopic part in this length state; when the second table board is turned outward to be horizontal with the first table board, the supporting plate on the supporting leg can abut against the bottom of the two table boards at the same time.

[0021] The vertical cabinet, the first table board, and the second table board in this embodiment are pivotally connected to each other and can be turned over freely. The supporting legs and the telescopic parts can fix the two table boards in specific turning states, including: in the folded state, the second table board is turned inward so that the second table board fits against the back of the first table board, and then the first table board is turned downward to a vertical drooping state, the receiving cavity is completely covered by the first table board, the second table board is located in the receiving cavity, the supporting legs are also received in the receiving cavity, and the telescopic parts are in a retracted state. At this time, the overall appearance of this embodiment is a simple cabinet, and its upper side can also be used to place objects; in the semi-expanded state, the first table board is turned over to a horizontal state, and the telescopic parts are in a semi-expanded state. The retractable part is in an extended state, and the length limit lock can lock the retractable part in this state to keep its length fixed, so that the two retractable parts can maintain the first table top in a horizontal state. This embodiment in this state is suitable for use when there are not many people; in the fully expanded state, on the basis of the semi-expanded state, the second table top is also flipped up to a horizontal state, and the supporting legs are taken out, and the positioning blocks on the support plate are engaged with the positioning grooves on the back of the two table tops. At this time, the supporting legs can simultaneously support the two table tops, and the two table tops are in an equal height state. This embodiment in this state has the largest desktop, and the load-bearing stability of the desktop is also better.

[0022] When the present embodiment is in a semi-expanded state, the center of gravity of the whole is away from the cabinet. Therefore, in order to prevent tipping over, the present embodiment needs to fix the cabinet to the wall at the placement position by means of expansion screws and connecting accessories to enhance the overall stability.

[0023] See Figure 5 The telescopic member includes a sleeve 81 pivotally connected to the side panel and a telescopic rod 82 pivotally connected to the first table board, and the telescopic rod is slidably inserted into the sleeve; the length limit lock is fixed on the sleeve, and a slot 83 is provided on the telescopic rod. The length limit lock is composed of a first lock shell 91, a latch 92 and a pull rod 93. The first lock shell is also provided with a first reset spring 94 that pushes the latch to move inside the sleeve; when the first table board is in a horizontal state, the slot is just opposite to the latch, and the first reset spring can push the latch into the slot, so that the telescopic member is locked. At the same time, the outer end of the pull rod extends to the outside of the first lock shell. By pulling the pull rod in the opposite direction, the latch can be driven out of the slot, thereby releasing the locking state of the telescopic member. It should be noted that when pulling the pull rod, it is necessary to hold the first table board by hand to reduce the friction between the latch and the slot.

[0024] See Figure 5A first limit plate 84 is provided inside the sleeve and near one end of the pivot connection, a second limit plate 85 is provided on the telescopic rod, and a buffer spring 86 is provided between the first limit plate and the second limit plate. When the first table board flips downward, the telescopic rod in the sleeve will shrink inward, so that the distance between the two limit plates is reduced. Because the first table board has a tendency to flip downward due to its own gravity, in order to avoid the accident of pinching the hand due to the first table board flipping too quickly, a buffer spring is provided between the two limit plates in this embodiment to absorb part of the kinetic energy, thereby playing a role in hindering the first table board from flipping down, which can effectively prevent the first table board from flipping too quickly. At the same time, it can also provide a certain lifting force when the first table board flips upward, which is more labor-saving to use. The normal length of the buffer spring does not necessarily have to be greater than or equal to the maximum distance between the two limit plates.

[0025] See Figure 4 The back of the first table board is also provided with a table board limit lock 100, which consists of a second lock shell 101, a sliding pin 102 slidingly arranged in the second lock shell, and a second return spring 103 that pushes the sliding pin to slide outward. The second lock shell also exposes a shift block 104 fixedly connected to the sliding pin. The front end of the sliding pin is set as an inclined surface. A lock hole 31 is opened on the side wall of the second table board. When the second table board is flipped to fit the back of the first table board, the front end of the sliding pin can be inserted into the lock hole to form a lock. The table board limit lock is used to fix the second table board in the folded state to prevent it from freely sagging in the semi-expanded state.

[0026] See Figure 7 In this embodiment, a screw rod 44 and a plastic block 45 fixed on the screw rod are screwed to the bottom of the support leg. By rotating the plastic block and the screw rod, the length of the support leg can be fine-tuned.

[0027] See Figure 6 In this embodiment, two side surfaces of the first table top are provided with concave recessed portions 22. The recessed portions are convenient for fingers to grasp so as to flip and control the first table top.

[0028] See Figure 1 In this embodiment, an elastic fastener 71 for fastening the supporting legs is provided on the connecting plate located on the back of the cabinet.

[0029] See Figure 1 and Figure 2 In this embodiment, a storage cabinet 12 is further provided on the upper side of the cabinet to enhance the overall storage function; a stepped receiving groove 51 is further formed on the front side of the side panel. In order to increase the tabletop area, the width of the two tabletops is set to be consistent with the width of the cabinet, and the stepped receiving groove can be used to accommodate the first tabletop and the second tabletop when in the folded state, so that the overall appearance of this embodiment is more seamless and concise when in the folded state.

[0030] The present invention can be modified in various ways which are obvious to those skilled in the art, and such modifications are not considered to depart from the scope of the present invention. All such modifications which are obvious to those skilled in the art are intended to be included within the scope of the present claims.
