Description

Technical Field

[0001] This application relates to the technical field of furniture, and in particular to a press-to-unlock hinge and a functional unit employing the same structure. Background Technology

[0002] With the development of the sofa industry, people's demand for coffee tables—the perfect complement to sofas—is also increasing. Coffee tables not only match sofas but can also store everyday items such as remote controls, books, and drinks.

[0003] Currently, there are two main types of coffee tables with storage functions on the market: The first type uses traditional hinges, which require overcoming the weight of the coffee table lid to open upwards. This combination requires a large opening force, and the opening force needs to be continuously applied until it is fully open. The second type uses a gas spring to assist in opening, and the connecting parts use common hinges. This combination is easier to open, but it requires overcoming a large gas spring resistance when closing, and the gas spring and hinges are fully exposed when open, resulting in a lower aesthetic appeal of the coffee table.

[0004] Based on the problems existing in the above structure, this application designs a press-to-unlock hinge that can open the cover of the storage box in the coffee table by pressing. Summary of the Invention

[0005] To enable the press-to-open mechanism of the storage box cover in a coffee table, this application provides a press-to-unlock hinge and a functional table using this structure.

[0006] In a first aspect, this application provides a press-to-unlock hinge, employing the following technical solution:

[0007] A push-to-unlock hinge, including

[0008] Hinge seat;

[0009] Hinged cover;

[0010] The guiding mechanism, connected between the hinge seat and the hinge cover, includes a rocker arm with its two ends rotatably connected to the hinge seat and the hinge cover respectively, a slide groove opened in an arc shape on the hinge seat, a sliding rod fixed to the hinge cover and slidably connected to the slide groove, and an elastic member connected between the hinge seat and the sliding rod.

[0011] A locking mechanism is provided on the hinge seat and located at the end of the slide groove away from the elastic element;

[0012] When the hinge cover is in the open state, the locking mechanism is unlocked, and the sliding rod is pressed against one end of the slide groove under the action of the elastic member's rebound force; pressing the open end of the hinge cover, the sliding rod moves along the slide groove until it is engaged with the locking mechanism to achieve locking; pressing the hinge cover n times, where n is not less than 1, the locking mechanism is unlocked, the elastic member resets, the sliding rod slides along the slide groove, and the hinge cover opens.

[0013] By adopting the above technical solution, the locking mechanism is opened and closed by pressing, and the hinge cover is automatically opened to the maximum state by using the elastic element, thus avoiding the need to continuously apply force to open the hinge cover.

[0014] Optionally, the locking mechanism includes a movable paddle rotatably connected to the hinge seat in the middle, a locking member disposed at one end of the movable paddle, a torsion member disposed at the rotation point of the movable paddle, and a locking member disposed at the other end of the movable paddle; when the hinge cover is in the open state, the locking member is unlocked, the torsion member is reset, and the locking member faces the direction of the elastic member.

[0015] By adopting the above technical solution, the sliding rod is locked via a movable paddle. When the hinge cover is open, the torsion member locks the position of the movable paddle, ensuring that the locking element always points towards the spring element. Therefore, during the closing of the hinge cover, the sliding rod accurately engages with the locking element to achieve locking. In addition, the torsion member also works with the spring element to provide driving force for opening the hinge cover.

[0016] Optionally, the locking component includes a locking rod rotatably connected to the end of the movable lever and a labyrinth lock disposed on the hinge seat. The locking rod is locked in the lock groove of the labyrinth lock and slides along the lock groove. The lock groove of the labyrinth lock is provided with n limit positions and m locking positions, where n=m+1 and m is not less than 1.

[0017] By adopting the above technical solution, when the locking lever slides to the locked position of the maze lock, the locking lever is locked, causing the movable lever to lock the position of the sliding rod, thereby locking the position of the hinge cover. When the maze lock has only one locked position, after pressing the hinge cover once to close it, only one more press is needed to open the hinge cover. If the maze lock has more than one locked position, after pressing the hinge cover once to close it, the number of presses required to open the hinge cover is equal to the number of locked positions. If there is more than one locked position, the probability of accidentally opening the hinge cover during use can be reduced, improving the comfort of use.

[0018] Optionally, the locking mechanism and the hinge cover are located on opposite sides of the hinge seat, while the elastic element and the locking mechanism are located on the same side of the hinge seat.

[0019] By adopting the above technical solution, interference between the locking mechanism or the spring component and the hinge cover and rocker arm rotation is avoided. Simultaneously, placing the spring component and locking mechanism on the same side of the hinge base improves the overall space utilization of the hinge base, thereby reducing the overall thickness of the push-to-unlock hinge. If one of the locking mechanism or spring component is located on the same side as the hinge cover, the length of the hinge cover and rocker arm rotation axis needs to be increased. This would leave sufficient space between the hinge cover and the hinge base sidewall, and between the rocker arm and the hinge base sidewall, for installing the locking mechanism or spring component, resulting in a larger overall thickness of the push-to-unlock hinge. Of course, placing both the locking mechanism and spring component on the same side of the hinge base as the hinge cover can also reduce the thickness of the push-to-unlock hinge. However, with the locking mechanism and spring component sandwiched between the rocker arm and the hinge base, the entire connection structure is not fully visible, which is detrimental to later maintenance and parts replacement. Therefore, placing the spring component and locking mechanism on one side of the hinge base and the hinge cover on the other side is the optimal choice.

[0020] Optionally, a raised ridge is added to the edge of the hinge seat corresponding to the slide groove, and the raised ridge is located on the side of the hinge seat where the elastic element is provided.

[0021] By adopting the above technical solution, a certain wall thickness of the slide groove is required during the movement of the sliding rod to ensure its stability during the sliding process. When a raised ridge is set around the edge of the slide groove, the overall thickness of the hinge seat can be reduced, while ensuring the stability of the sliding rod movement, thereby reducing the overall thickness of the press-to-unlock hinge.

[0022] Optionally, an outer cover is added to the side of the hinge seat away from the hinge cover, and the elastic element and locking mechanism are hidden between the hinge seat and the outer cover.

[0023] By adopting the above technical solution, the elastic element and locking mechanism are hidden between the hinge seat and the outer cover, which can protect the elastic element and locking mechanism, extend their service life, and close the entire hinge seat into a stable whole, making it easy to remove and replace them individually.

[0024] Optionally, the rocker arm is provided with a damping element at the rotation point where it is connected to the hinge seat to reduce the rotation speed of the rocker arm.

[0025] By adopting the above technical solution, the damping component can slow down the rotation speed of the rocker arm. The rocker arm, connected to the hinge cover, controls the rotation of the hinge cover, thus slowing its rotation and preventing rapid rotation. When the hinge cover needs to connect to materials with significant weight, or when the force applied to the material being connected to the hinge cover is excessive, the damping component can buffer the acceleration generated by these forces, allowing the hinge cover to move slowly to the desired position, reducing the probability of collisions and noise.

[0026] Optionally, the side of the hinge cover used for connecting objects when the hinge cover is open is located in the middle of the side of the hinge cover used for connecting objects when the hinge cover is closed.

[0027] By adopting the above technical solution, when the hinge cover is opened, the end of the plate connected to the hinge cover can enter the space enclosed by the plate, thereby reducing the volume of the plate exposed outside the space and improving the aesthetics of the entire structure when open.

[0028] Secondly, this application provides a functional unit, which adopts the following technical solution:

[0029] A functional cabinet includes a hollow storage box with an opening on one side and a cover plate disposed on one side of the opening of the storage box, wherein a storage chamber is formed inside the storage box; a press-to-unlock hinge is disposed between the cover plate and the side plate; the hinge seat is fixed to the side plate, and the hinge cover is fixed to the bottom of the cover plate; when the hinge cover is opened, the end of the cover plate enters the storage chamber.

[0030] By adopting the above technical solution, the hinge cover's running trajectory allows the closed cover to close the chamber, and the open cover's end to enter the storage chamber, thus reducing the amount of cover exposed outside the storage chamber and improving the functionality and aesthetics of the open state. Furthermore, because the press-to-unlock hinge is installed as an independent unit between the cover and the storage box, it avoids the connecting structure being exposed outside the storage chamber when open, and also facilitates the overall installation and removal of the press-to-unlock hinge.

[0031] Optionally, a locking button is added between the cover and the storage box. When the cover closes the opening of the storage box, the locking button locks the relative position of the cover and the storage box. Pressing the locking button unlocks the storage box and the cover.

[0032] By adopting the above technical solution, the locking button is designed so that the opening and closing of the hinge can only be operated after the locking button is unlocked. This avoids the situation where the cover is accidentally opened when it is not needed, thus improving the user's comfort during the use of the functions.

[0033] In summary, the present invention has at least one of the following beneficial technical effects:

[0034] 1. The guide mechanism and locking mechanism enable the hinge cover to open automatically after being pressed relative to the hinge seat, reducing the need for manual labor;

[0035] 2. The elastic element and locking mechanism are placed on one side of the hinge base, and the outer cover is used to hide the former two between the hinge base and the outer cover, which makes the hinge base more integral and reduces the manufacturing thickness, making it easier to install and remove the hinge by pressing to unlock it.

Detailed Implementation

[0046] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0047] Reference Figure 1 and Figure 2This application discloses a press-to-unlock hinge, which includes a hinge base 1, a hinge cover 2, a guide mechanism 3, and a locking mechanism 7. The hinge cover 2 rotates on the hinge base 1 under the guidance of the guide mechanism 3 to open and close. When closed, the hinge cover 2 is locked by the locking mechanism 7. Pressing the hinge cover 2 several times unlocks the locking mechanism 7, allowing the hinge cover 2 to open. Rotating the opened hinge cover and pressing it further locks the hinge cover 2 under the guidance of the guide mechanism 3 and the locking mechanism 7.

[0048] Reference Figure 2 and Figure 3 The hinge base 1 is a square, thin sheet with one upper edge protruding outwards at the center to accommodate component installation. Countersunk holes 11 are provided at the four corners of the hinge base 1 to facilitate later installation onto other structures. A ring of protruding mounting ridges 5 is formed around the area enclosed by the four countersunk holes 11. The mounting ridges 5 and the countersunk positions of the countersunk holes 11 are located on both sides of the hinge base 1, while the hinge cover 2 and the mounting ridges 5 are also located on both sides of the hinge base 1. An outer cover 13 covers the mounting ridges 5, and the outer cover 13, mounting ridges 5, and hinge base 1 cooperate to form a cavity. Screw holes are provided at the four corners of the hinge base 1 corresponding to the mounting ridges 5, and the outer cover 13 is fixed to the hinge base 1 through these four screw holes.

[0049] Reference Figure 2 and Figure 4 The guiding mechanism 3 includes a rocker arm 31 connected between the hinge seat 1 and the hinge cover 2, a slide groove 32 formed on the hinge seat 1, a sliding rod 33 fixed to one side of the hinge cover 2, and a spring member 34 connected between the sliding rod 33 and the hinge seat 1. The sliding rod 33 slides along the slide groove 32 and is locked at one end of the slide groove 32 under the limitation of the spring member 34. A force is applied to the hinge cover 2 to overcome the elastic force of the spring member 34, causing it to move along the slide groove 32 until it is locked by the locking mechanism 7.

[0050] One end of the rocker arm 31 is rotatably connected to the hinge cover 2, and the other end passes through the hinge seat 1 and is rotatably connected to the hinge seat 1. In order to buffer the rotation speed of the rocker arm 31, a damping element 4 is added between the rocker arm 31 and the hinge seat 1. The damping element 4 is located in the area enclosed by the mounting ridge 5.

[0051] The damping element 4 can be a conventional structure for constraining rotational speed or the structure disclosed in this application. In this embodiment, the damping element 4 includes a drive gear 41 fixed to the rocker arm 31 and a damping gear 42 meshing with one side of the drive gear 41. The damping gear 42 is rotatably connected to the hinge seat 1. The drive gear 41 corresponds to the outwardly protruding area on the hinge seat 1, thereby reducing the material used in the hinge seat 1 and saving costs.

[0052] The groove 32 is formed within the area enclosed by the mounting ridge 5. The edge of the mounting ridge 5 adjacent to the outwardly protruding side of the hinge seat 1 is named the protruding edge 52, and the edge corresponding to the protruding edge 52 is named the straight edge 51. The groove 32 begins at one end of the straight edge 51, extends towards the middle of the protruding edge 52, then bends towards the edge between the other end of the straight edge 51 and the protruding edge 52, finally terminating at the middle of the hinge seat 1. The starting end of the groove 32 is named the beginning end 321, and the ending end of the groove 32 is named the end end 322. A ring of protruding ridges 6 is provided on the hinge seat 1 corresponding to the edge of the groove 32. The protruding ridges 6 are located within the area enclosed by the mounting ridge 5, thereby reducing the required thickness of the hinge seat 1.

[0053] The sliding rod 33 passes through the groove 32, and one end of the sliding rod 33 passing through the groove 32 is connected to the elastic element 34. The elastic element 34 is a tension spring or other conventional elastic structure; in this embodiment, a tension spring is used as an example. One end of the tension spring is sleeved on the outside of the sliding rod 33 and rotates with it, while the other end is sleeved on a rotating shaft fixed to the hinge seat 1 and rotates with the rotating shaft. The rotating shaft is located near the end of the protruding edge 52 adjacent to the groove 32.

[0054] The locking mechanism 7 is located within the area enclosed by the mounting ridge 5. It includes a movable paddle 71 rotatably connected to the hinge seat 1 in the middle, a locking member 72 located at one end of the movable paddle 71, a locking member 73 located at the other end of the movable paddle 71, and a torsion member 74 located at the rotation point of the movable paddle 71. When the hinge cover 2 is open, the movable paddle 71 is limited by the torsion member 74, causing the locking member 72 to always face the tension spring, while the locking member 73 is in the unlocked state. After pressing the hinge cover 2, the sliding rod 33 moves along the slide groove 32 toward the movable paddle 71, and the sliding rod 33 engages with the locking member 72 and continues to move until the locking member 73 locks in place.

[0055] The movable lever 71 is triangularly shaped, with a locking member 73 located at one corner of the movable lever 71, and a locking member 72 located in a slot between the other two corners of the movable lever 71. The torsion member 74 can be any structure that restricts rotation. In this embodiment, the torsion member 74 is a torsion spring sleeved on the rotation point of the movable lever 71, with one end of the torsion spring pressed against the straight edge 51 and the other end inserted into the movable lever 71 for fixation.

[0056] The locking element 73 is disposed between the movable lever 71 and the damping gear 42, and includes a locking rod 731 connected to the movable lever 71 and a labyrinth lock 732 integrally disposed on the hinge seat 1. One end of the locking rod 731 is rotatably connected to the corner of the movable lever 71, and the other end is inserted into the lock groove of the labyrinth lock 732. The lock groove of the labyrinth lock 732 is provided with n limit positions 7321 and m locking positions 7322, where n=m+1, m is not less than 1, and it is preferable to provide one or two locking positions 7322. When the locking rod 731 is in the locking position 7322, the movable lever 71 is locked.

[0057] Reference Figure 2 and Figure 5 The dynamic operation of the hinge unlocking mechanism is as follows: When the hinge cover 2 is in the open state, the sliding rod 33 is pressed against the end 322 of the slide groove 32 under the action of the tension spring, and the movable paddle 71 is locked under the action of the torsion spring. At the same time, the slot faces the tension spring, and the locking rod 731 is located at the opening of the locking groove. Pressing one open end of the hinge cover 2 drives the sliding rod 33 to move towards the beginning end 321 in the slide groove 32. At the same time, the hinge cover 2 rotates along a predetermined path under the joint limitation of the sliding rod 33 and the rocker arm 31. When the sliding rod 33 moves to the slot position and engages in the slot, the sliding rod 33 drives the movable paddle 71 to rotate towards the beginning end 321 of the slide groove 32. The torsion spring bears the torque, and at the same time, the locking rod 731 slides along the locking groove and passes through a limit position 7321 until it engages in the first locking position 7322, locking the hinge cover 2.

[0058] If a locking position 7322 is provided, when the hinge cover 2 needs to be opened, pressing the hinge cover 2 causes the sliding rod to continue moving towards the beginning 321 of the slide groove 32. The locking rod 731 continues to slide along the lock groove and passes through the second limit position 7321 of the lock groove to unlock. The movable lever 71 rotates towards the end 322 of the slide groove 32 under the combined action of the torsion spring and the tension spring, while the sliding rod 33 slides along the slide groove 32 under the elastic force of the tension spring. Under the deceleration action of the damping gear 42, the rocker arm 31 restricts the hinge cover 2 to rotate slowly until the sliding rod 33 abuts against the end 322 of the slide groove 32, and the hinge cover 2 is fully opened. In the open state, the side of the hinge cover 2 used for connecting objects is located in the middle of the side of the hinge cover 2 used for connecting objects in the closed state.

[0059] If there are two locking positions 7322, when the hinge cover 2 needs to be opened, both sides of the hinge cover 2 need to be pressed so that the locking rod 731 slides past the remaining two limit positions 7321 before it can be opened.

[0060] Reference Figure 6 This application also discloses a functional cabinet that uses a press-to-unlock hinge, which includes a storage box 8 and a storage box 9.

[0061] A wireless charger 81 or other user-friendly components can be installed on the top of the storage box 8, and a cup holder 82 is slidably connected to one side of the storage box 8.

[0062] Reference Figure 6 and Figure 7The storage box 9 has an open top and is hollow, forming a storage chamber 91 inside. Several cover plates 92 are provided on one side of the opening of the storage box 9; this embodiment uses two cover plates 92 as an example. Each cover plate 92 has a press-to-unlock hinge at both ends. The hinge seat 1 is fixed to the inner wall of the storage box 9, and the hinge cover 2 is fixed to the side wall of the cover plate 92. When the cover plate 92 is in the open state, the end of the cover plate 92 enters the storage chamber 91, thereby reducing the exposed cover plate 92.

[0063] Reference Figure 8 and Figure 9 To prevent accidental opening of the cover 92, a locking button 10 is provided between the cover 92 and the inner wall of the storage box 9. Pressing the locking button 10 engages the locking mechanism between the cover 92 and the storage box 9; releasing the locking button 10 locks the cover 92 and the storage box 9.

[0064] The cover plate 92 has an installation chamber 921 inside, and the surface of the cover plate 92 has an installation groove 922 that communicates with the installation chamber 921. The locking button 10 includes a button inserted into the installation groove 922, an L-shaped lever 102 connected to the inner wall of the installation chamber 921, a connecting rod 103 connected to the lever 102, and a plug 104 connected to the end of the connecting rod 103.

[0065] The button slides along the mounting groove 922 and is located directly above one end of the lever 102. The L-shaped turning point of the lever 102 is rotatably connected to the inner wall of the mounting chamber 921, and a torsion spring is provided at the turning point of the lever 102 to facilitate the return of the lever 102 to its original position. The other end of the lever 102 is rotatably connected to one end of the connecting rod 103, and the other end of the connecting rod 103 is rotatably connected to one end of the insertion rod 104. The other end of the insertion rod 104 passes through the end face of the cover plate 92 and slides along the hole in the cover plate 92.

[0066] The inner wall of the storage box 9 has a slot 93. In the initial state, the rod 104 is inserted into the slot 93, the button is near the top of the mounting slot 922, and the relative position of the cover 92 and the storage box 9 is locked. Pressing the button drives the lever 102 to move downward at one end below the button, causing the other end of the lever 102 to rotate upward, driving the rod 104 away from the slot 93 until it is disengaged. At this time, pressing the cover 92 drives the hinge cover 2 to rotate, causing the cover 92 to open.

[0067] The embodiments described herein are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
