Description

Technical Field

[0001] The utility model relates to the technical field of massage chairs, leisure chairs or foot bath chairs, and in particular to a tea table board slide plate clamping column type three-lever storage and extension mechanism suitable for massage chairs, leisure chairs or foot bath chairs. Background Art

[0002] Currently, massage chairs, foot massage chairs, and leisure chairs on the market often feature a coffee table panel on the side of their armrests. This panel can be flipped to a vertical position and stored against the outside of the armrest, or flipped to a horizontal position, making it convenient for placing items such as tea sets and mobile phones. The coffee table panel and armrest are typically connected by a hinge structure, with a supporting structure to support the panel when it is flipped to a horizontal position, preventing it from flipping over. This traditional hinge structure lacks an effective locking mechanism when the panel is flipped back to its vertical storage position, making it prone to shaking and colliding with the armrest, generating noise. Especially for foot massage chairs with armrests that can open and close (to facilitate getting in and out of the chair), the coffee table panel tends to extend automatically when the armrest flips, hindering ease of use, making operation inconvenient, and reducing the space required for the chair. Furthermore, traditional hinge structures for the coffee table panel have a certain thickness when it is stowed, resulting in a certain distance between the panel and the armrest, which affects the overall aesthetics. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, the utility model provides a three-lever storage and extension mechanism for a coffee table board slide plate, which can lock the coffee table board when it is flipped and stored to prevent it from extending on its own.

[0004] The utility model discloses a coffee table board skateboard card column type three-lever storage and extension mechanism, including a flip hinge component, a fixed hinge component, and a support hinge component, wherein the fixed hinge component has an upper connecting end that is installed and fixed in cooperation with the armrest and a side connecting end that is connected in cooperation with the flip hinge component and the support hinge component, wherein the flip hinge component is used to be installed and fixed in cooperation with the coffee table board, and the fixed hinge component can be fixedly installed at the top inner wall of the concave hole of the armrest of chairs such as massage chairs, foot bath chairs, and leisure chairs through its upper connecting end, one end of the flip hinge component and one end of the support hinge component are rotatably connected to the upper and lower parts of the side connecting end of the fixed hinge component, respectively, so as to realize the flip function of the coffee table board relative to the armrest, and the other end of the support hinge component cooperates with the flip hinge component to support, so that the flip hinge component and the fixed hinge component can be fixedly installed at the top inner wall of the concave hole of the armrest of chairs such as massage chairs, foot bath chairs, and leisure chairs through its upper connecting end. The fixed hinge member and the supporting hinge member can form a stable triangular support structure by rotating, thereby preventing the flip hinge member from flipping downward by itself under the action of gravity. A positioning module is provided between the other end of the supporting hinge member and the flip hinge member, which can lock the other end of the supporting hinge member and the other end of the flip hinge member when they are rotated downward to a vertical state. When the flip hinge member and the supporting hinge member are locked, the two are restricted from rotating relative to the fixed hinge member, thereby preventing the coffee table plate from rotating relative to the armrest. This can avoid collision and noise due to shaking between the coffee table plate and the armrest or between the various components of the hinge mechanism when massage chairs, foot bath chairs, leisure chairs and other chairs are working, and can also prevent the coffee table plate from extending by itself when the armrest opens and closes, thereby improving the use effect.

[0005] Furthermore, the positioning module includes a positioning hole provided on the flip hinge member and a positioning unit provided on the other end of the support hinge member. The positioning unit includes a clip that moves between a locked position and an unlocked position and a spring that drives the clip to return to the locked position. The front end of the clip engages with the positioning hole for positioning and has an arcuate contact surface. Because the front end of the clip has an arcuate contact surface, the clip can be moved in an unlocking direction when it contacts the flip hinge member. When the front end of the clip moves to the positioning hole, it can move to the locked position, cooperating with the positioning hole to achieve a snap-fit positioning between the flip hinge member and the support hinge member. When a large force is applied to the flip hinge member, the clip can also be urged to move to the unlocked position, thereby achieving separation between the flip hinge member and the support hinge member, which is relatively easy to operate.

[0006] Furthermore, the positioning unit includes a shell, the clamping piece is a steel ball, the shell and the supporting hinge component are connected, the shell includes an inner cavity for installing the steel ball and the spring, and the shell is provided with a through hole for partially extending the steel ball outward. The positioning unit and the positioning hole are each in two groups, which cooperate with the two sides of the flip hinge component for positioning respectively. The structure is simple, which makes the force between the flip hinge component and the supporting hinge component more uniform, can reduce shaking, and improve the positioning effect.

[0007] Furthermore, the other end of the supporting hinge member and the bottom of the flip hinge member cooperate to abut and support each other, and a positioning groove is provided on the flip hinge member. The other end of the supporting hinge member cooperates with the positioning groove of the flip hinge member to position, and can maintain the flip hinge member in a horizontal state, avoiding relative movement between the other end of the supporting hinge member and the bottom of the flip hinge member, thereby improving the supporting effect of the coffee table board.

[0008] Furthermore, a limiting groove is provided at the other end of the flip hinge component, and the limiting groove is provided with a notch in the direction of one end of the corresponding flip hinge component. The other end of the supporting hinge component can be inserted into the limiting groove along the notch and form a limiting cooperation therewith. When the flip hinge component and the supporting hinge component are flipped downward for storage, the other end of the supporting hinge component can be inserted into the limiting groove, thereby improving the positioning effect of the flip hinge component and the supporting hinge component.

[0009] Furthermore, an operating member is swingably connected to the flip hinge member, one end of the operating member can be driven by hand to swing, and the other end of the operating member forms a pushing fit with the other end of the supporting hinge member. When the coffee table board needs to be stored, the user can use the operating member to push the other end of the supporting hinge member out of the positioning groove, so that the flip hinge member and the coffee table board can be flipped down for storage.

[0010] Furthermore, a spring is provided between the operating member and the flip hinge member, and the spring is used to drive the other end of the operating member to swing back in a direction away from the supporting hinge member. The setting of the spring can reduce the shaking between the operating member and the flip hinge member and reduce noise.

[0011] Furthermore, a tension spring is provided between the support hinge member and the fixed hinge member. The tension of the tension spring is used to drive the other end of the support hinge member to rotate and abut against the bottom of the flip hinge member. When the flip hinge member flips downward, the other end of the support hinge member can move along the bottom of the flip hinge member. When flipped to the storage state, the other end of the support hinge member can be accurately inserted into the retaining groove, making operation more convenient. Similarly, when the flip hinge member flips upward, the other end of the support hinge member can also move along the bottom of the flip hinge member to the positioning groove and form a fixed fit.

[0012] The beneficial effects of the present invention are as follows: the coffee table board slide plate column type three-lever storage and extension mechanism of the present invention can be used to establish a flip connection and support cooperation between the coffee table board and the armrest of the chair, and can also achieve self-locking when the coffee table board is flipped to the storage state, preventing it from flipping and extending by itself during use.

[0024] The structure of a three-lever storage and extension mechanism of a tea table slide plate in an embodiment of the utility model is as follows Figure 1-11As shown, it includes a flip hinge component 1, a fixed hinge component 2, and a support hinge component 3. The fixed hinge component 2 has an upper connecting end that is fixedly mounted with the armrest a and a side connecting end that is connected to the flip hinge component 1 and the support hinge component 3. The flip hinge component 1 is used to be fixedly mounted with the coffee table board b, and the fixed hinge component 2 can be fixedly mounted on the top inner wall of the concave hole of the armrest a of a massage chair, a foot bath chair, a leisure chair, etc. through its upper connecting end (such as Figure 3 As shown), the mating surface connected to the armrest a is arranged parallel to the ground, and one end of the flip hinge component 1 and one end of the support hinge component 3 are respectively rotatably connected to the upper and lower parts of the side connection end of the fixed hinge component 2, which can realize the flip function of the coffee table board b relative to the armrest a. The other end of the support hinge component 3 cooperates with the flip hinge component 1 to support, so that the flip hinge component 1, the fixed hinge component 2 and the support hinge component 3 can form a stable triangular support structure by rotation, preventing the flip hinge component 1 from flipping downward by itself under the action of gravity. The other end of the support hinge component 3 and the flip hinge are connected to the upper and lower parts of the side connection end of the fixed hinge component 2. A positioning module is provided between the components 1, which can lock the other end of the supporting hinge component 3 and the other end of the flip hinge component 1 when they are rotated downward to a vertical state. When the flip hinge component 1 and the supporting hinge component 3 are locked, the two are restricted from rotating relative to the fixed hinge component 2, thereby preventing the coffee table board b from rotating relative to the armrest a. This can avoid collision and noise due to shaking between the coffee table board b and the armrest a or between the various components of the hinge mechanism when massage chairs, foot bath chairs, leisure chairs and other chairs are in operation, and can also prevent the coffee table board b from extending out by itself when the armrest a opens and closes, thereby improving the use effect.

[0025] like Figure 11 As shown, the positioning module includes a positioning hole 11 provided on the flip hinge member 1, a positioning unit provided on the other end of the support hinge member 3, the positioning unit includes a clamp 41 that moves between a locked position and an unlocked position, and a spring 42 that drives the clamp 41 to return to the locked position. The front end of the clamp 41 is engaged with the positioning hole 11 for positioning and has an arc-shaped contact surface. Due to the arc-shaped contact surface, the front end of the clamp 41 can move the clamp 41 in the unlocking direction when it contacts the flip hinge member 1. When the front end of the clamp 41 moves to the positioning hole 11, it can move to the locked position, and cooperate with the positioning hole 11 to achieve the clamping and positioning cooperation between the flip hinge member 1 and the support hinge member 3. When a large force is applied to the flip hinge member 1, the clamp 41 can also be urged to move to the unlocked position, thereby achieving separation between the flip hinge member 1 and the support hinge member 3, which is relatively easy to operate.

[0026] The positioning unit includes a shell 43, the clamping member 41 is a steel ball, the shell 43 and the supporting hinge member 3 are connected as a whole, the shell 43 includes an inner cavity for installing the steel ball and the spring 42, and the shell 43 is provided with a through hole 431 for partially extending the steel ball outward. The positioning unit and the positioning hole 11 are both in two groups, which cooperate with the two sides of the flip hinge member 1 for positioning respectively. The structure is simple, which makes the force between the flip hinge member 1 and the supporting hinge member 3 more uniform, can reduce shaking, and improve the positioning effect.

[0027] The other end of the supporting hinge member 3 and the bottom of the flip hinge member 1 cooperate to abut and support each other. A positioning groove 12 is provided on the flip hinge member 1. The other end of the supporting hinge member 3 cooperates with the positioning groove 12 of the flip hinge member 1 to position, and can keep the flip hinge member 1 in a horizontal state, avoiding relative movement between the other end of the supporting hinge member 3 and the bottom of the flip hinge member 1, thereby improving the supporting effect of the coffee table board b.

[0028] A limiting groove 51 is provided at the other end of the flip hinge component 1, and the limiting groove 51 is provided with a notch in the direction of one end of the corresponding flip hinge component 1. The other end of the supporting hinge component 3 can be inserted into the limiting groove 51 along the notch and form a limiting cooperation therewith. When the flip hinge component 1 and the supporting hinge component 3 are flipped downward for storage, the other end of the supporting hinge component 3 can be inserted into the limiting groove 51, thereby improving the positioning effect of the flip hinge component 1 and the supporting hinge component 3.

[0029] The flip hinge component 1 is swingably connected to an operating component 5, and one end 52 of the operating component 5 can be driven by the hand to swing, and the other end of the operating component 5 forms a pushing fit with the other end of the supporting hinge component 3. When the coffee table board b needs to be stored, the user can use the operating component 5 to push the other end of the supporting hinge component 3 out of the positioning groove 12, so that the flip hinge component 1 and the coffee table board b can be flipped downward for storage.

[0030] In this embodiment, the operating member 5 is integrally formed with a hook portion, and the limiting groove 51 is formed by a recess in the hook portion. The operating member 5 is connected to the flip hinge member 1 via a screw 61, which is provided with a spring 62. The spring 62 drives the operating member 5 to press against the flip hinge member 1. The penetration connection between the screw 61 and the operating member 5 has a gap that allows the operating member 5 to swing. The upper portion of the operating member 5 is provided with a protrusion 53 for contacting and cooperating with the flip hinge member 1, which can serve as a fulcrum for the operating member 5 to swing. The spring 62 can drive the operating member 5 to swing the other end of the operating member 5 away from the support hinge member 3 and return it to its original position. The provision of the spring 62 can reduce the shaking between the operating member 5 and the flip hinge member 1, thereby reducing noise.

[0031] A tension spring 7 is provided between the support hinge member 3 and the fixed hinge member 2. One end of the tension spring 7 connected to the fixed hinge member 2 is connected to the shaft of the fixed hinge member 2 that is pivotally connected to the flip hinge member 1. Of course, it can also be directly connected to the fixed hinge member 2. The tension of the tension spring 7 is used to drive the other end of the support hinge member 3 to rotate and abut against the bottom of the flip hinge member 1. When the flip hinge member 1 flips downward, the other end of the support hinge member 3 can slide along the bottom of the flip hinge member 1. When it is flipped to the storage state, it can prompt the other end of the support hinge member 3 to be accurately inserted into the limiting groove 51, making operation more convenient. Similarly, when the flip hinge member 1 flips upward, the other end of the support hinge member 3 can also slide along the bottom of the flip hinge member 1 to the positioning groove 12 and form a positioning fit.

[0032] The above embodiment is only one preferred embodiment of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention are all included in the protection scope of the present invention.
