Description

Technical Field

[0001] The utility model relates to a cabinet, in particular to a cabinet door upper opening mechanism for a lifting cabinet. Background Art

[0002] Wall cabinets, essential storage spaces within residential units, are typically installed on the upper walls of kitchens or other rooms. With their back panels fixed directly to the wall, these cabinets effectively utilize the space above the countertop, increasing storage capacity and accommodating more items. However, the design and installation height of wall cabinets are often influenced by height differences among family members. To ensure convenient access for all family members, wall cabinets are typically mounted too high. This limits the overall volume of the cabinets and makes accessing items from elevated locations difficult.

[0003] To address this issue, a liftable wall cabinet has emerged. This structure allows the cabinet to be lowered to the same height as the countertop during use, making it easier for users to access and place items. Once finished, the cabinet can be raised back up to a higher position, hidden within the wall cabinet. This design not only allows the cabinet to be installed at a higher location, but also increases its internal capacity, resolving the conflict between ease of use and storage capacity.

[0004] However, this type of liftable wall cabinet structure also presents some practical problems. Since the wall cabinet is level with the countertop when it is lowered, the area below the wall cabinet must remain clear and free of any items. However, in conventional kitchen designs, the area beneath the wall cabinet is typically used to store items such as stoves, pots, utensils, and condiments. Therefore, to achieve a clear area under the wall cabinet, the user must clear all items before each lift, which is extremely inconvenient in practice. Therefore, further improvements are necessary. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a lifting cabinet door upper opening mechanism with a simple structure and easy use, which can continue to realize the lifting function of the wall cabinet without affecting the use of the space below the wall cabinet.

[0006] The purpose of the utility model is achieved by the following method: a cabinet door upper opening mechanism for a lifting cabinet, comprising a vertical guide rail fixed on the cabinet body, a side push slider and a lifting slider being slidably mounted in the vertical guide rail, a transverse guide rail being mounted on the side push slider, a transverse bracket being slidably mounted on the transverse guide rail via the transverse slider, and the cabinet door being fixed on the transverse bracket;

[0007] The lifting slider is located at the bottom of the side push slider and is driven by a power mechanism to move up and down along the vertical guide rail. The lifting slider is equipped with an oblique push block that connects to the guide slider mounted on the transverse bracket. When the lifting slider moves upward, the oblique push block pushes the guide slider outward, which in turn drives the transverse bracket outward, thereby pushing the cabinet door outward. The contact surface between the guide slider and the oblique push block is an inclined surface with a higher top and a lower bottom.

[0008] Furthermore, the side walls of the horizontal bracket are also provided with guide wheels, and the corresponding cabinet body is provided with guide grooves. When the cabinet door is in a closed state, the guide wheels are inserted into the guide grooves.

[0009] Furthermore, the oblique push block is made of wear-resistant rubber and is arranged in a trapezoidal shape with a narrow upper portion and a wide lower portion. The waist portion of the oblique push block contacts the guide slider.

[0010] Furthermore: a lifting lug is extended rearwardly from the rear of the lifting slider, and the lifting lug is connected to the power mechanism.

[0011] Furthermore: a bottom plate is installed on the inner side of the vertical guide rail, and a panel is covered on the outer side, and a receiving area is formed between the bottom plate and the panel, and the vertical guide rail side push slider and the lifting slider are installed in the receiving area.

[0012] Furthermore: a connecting seat is provided on the top of the horizontal bracket, a vertically extending hanging slot is provided on the connecting seat, a base is installed on the back of the cabinet door, a hook is extended backward from the base, and the hook is hooked into the hanging slot and connected thereto.

[0013] Furthermore: a safety buckle is hingedly installed on the connecting seat, and the safety buckle is located on the back of the hanging slot. After the hook is hooked, the safety buckle presses on the top of the hook to limit its separation from the hanging slot.

[0014] The beneficial effects of the utility model are: 1. Simple structure, low production cost and improved market competitiveness.

[0015] 2. The top-opening mechanism of this utility model utilizes vertical guides and horizontal brackets to enable the cabinet door to move both vertically and horizontally. This allows the cabinet door to slide outward and upward to open, rather than simply dropping to the same height as the countertop. This design allows users to easily access items within the wall cabinet while effectively avoiding the space below the cabinet, allowing other kitchen items, such as stoves, tableware, and condiments, to remain below the wall cabinet, thereby improving kitchen space utilization.

[0026] The present invention will be further described below in conjunction with the accompanying drawings. A cabinet door opening mechanism for a liftable cabinet includes a vertical guide rail 2 fixed to a cabinet body 1, a side push slider 3 and a lift slider 4 being mounted in an up-and-down sliding manner within the vertical guide rail 2, a transverse guide rail 5 being mounted on the side push slider 3, a transverse bracket 6 being mounted in a transverse sliding manner on the transverse guide rail 5 via a transverse slider 51, and a cabinet door 11 being fixed to the transverse bracket 6.

[0027] The lifting slider 4 is located at the bottom of the side pushing slider 3, and the lifting slider 4 is driven by the power mechanism 7 to move up and down along the vertical guide rail 2; the lifting slider 4 is provided with an oblique pushing block 41 connected to the guide slider 63 provided on the horizontal bracket 6. When the lifting slider 4 moves upward, the oblique pushing block 41 is used to push the guide slider 63 to move outward, and the guide slider 63 drives the horizontal bracket 6 to slide outward, thereby pushing the cabinet door 11 outward to open.

[0028] In one embodiment, the contact surface between the guide sliding block 63 and the oblique push block 41 is an inclined surface with a higher top and a lower bottom.

[0029] In one embodiment, the side wall of the horizontal bracket 6 is further provided with a guide wheel 61 , and the corresponding cabinet body 1 is provided with a guide groove 62 . When the cabinet door 11 is in a closed state, the guide wheel 61 is inserted into the guide groove 62 .

[0030] In one embodiment, the oblique push block 41 is made of wear-resistant rubber and is arranged in a trapezoidal shape with a narrow upper portion and a wide lower portion. The waist portion of the oblique push block 41 contacts the guide slider 63 .

[0031] In one embodiment, a lifting lug 42 is extended rearward from the rear of the lifting slider 4 , and the lifting lug 42 is connected to the power mechanism 7 .

[0032] In one embodiment, a bottom plate 8 is installed on the inner side of the vertical guide rail 2 and a panel 81 is covered on the outer side. A receiving area is formed between the bottom plate 8 and the panel 81. The vertical guide rail 2 side push slider 3 and the lifting slider 4 are installed in the receiving area.

[0033] In one embodiment, a connecting seat 9 is provided on the top of the horizontal bracket 6, and a vertically extending hanging groove 91 is provided on the connecting seat 9. A base 92 is installed on the back of the cabinet door 11, and a hook 93 extends backward from the base 92. The hook 93 is hooked into the hanging groove 91 and connected thereto.

[0034] In one embodiment, a safety buckle 94 is hingedly mounted on the connecting seat 9 , and the safety buckle 94 is located on the back of the hanging slot 91 . After the hook 93 is hooked, the safety buckle 94 presses on the top of the hook 93 to prevent it from separating from the hanging slot 91 .

[0035] Working Principle: This mechanism comprises a vertical guide rail 2 fixed to the cabinet body, within which are mounted a side-pushing slider 3 and a lifting slider 4. When the cabinet door needs to be lowered to open, the power mechanism 7 is activated, and the lifting slider 4 moves upward along the vertical guide rail 2. At this point, the side-pushing slider 3 is connected to the transverse bracket 6 via the transverse guide rail 5, to which the cabinet door 11 is fixed. As the lifting slider 4 rises, the oblique push block 41 mounted thereon pushes the guide slider 63 mounted on the transverse bracket outward. This oblique thrust causes the transverse bracket 6 to slide outward along the transverse guide rail 5, thereby driving the cabinet door 11 to move outward and open.

[0036] When the lifting slide 4 rises to a certain height, the thrust of the oblique push block 41 on the guide slide 63 reaches its maximum, and the transverse bracket 6 slides outward to its full position, fully opening the cabinet door 11. The closing process of the cabinet door is the reverse of the downward movement of the lifting slide 4. The oblique push block 41 no longer exerts thrust on the guide slide 63, and the transverse bracket 6 returns to its original position along the transverse guide rail 5 under the action of gravity or the elastic return device, closing the cabinet door 11.

[0037] The sidewalls of the transverse bracket 6 are also provided with guide wheels 61, which engage within guide grooves 62 on the cabinet 1 during movement, ensuring that the transverse bracket 6 remains stable during sliding without shaking or deflection. The contact surface between the guide slider 63 and the oblique push block 41 is an inclined surface with a higher top and a lower bottom. This design provides a more stable thrust and further improves the stability of the mechanism.

[0038] Furthermore, the oblique push block 41 is made of wear-resistant rubber and designed in a trapezoidal shape, narrow at the top and wide at the bottom. This allows for closer contact with the guide slider 63 and moderate friction, thereby reducing wear and tear during long-term use and extending the service life of the mechanism. Furthermore, the lifting slider 4 is connected to the power mechanism 7 via a rearwardly extending lug 42, ensuring that the lifting slider's trajectory is always controlled, preventing accidental derailment or jamming.

[0039] When the cabinet door is pushed outwards into position, the power mechanism continues to pull the lifting slider upwards, which drives the horizontal slider and horizontal bracket to continue to lift upwards, thereby fully opening the cabinet door. When the user needs to close the door, the power mechanism lifts the cabinet upwards while releasing the lifting slider. The lifting slider returns to its original position under the weight of the cabinet door, thus closing the cabinet door.

[0040] Among them, in order to facilitate the installation and removal of the cabinet door, a connecting seat 9 is provided on the top of the horizontal bracket 6 in this case, and a hanging slot 91 extending vertically is provided on the connecting seat. A base 92 is installed on the back of the cabinet door 11, and a hook 93 extends backward from the base. The hook is embedded in the hanging slot by a hook to ensure that the cabinet door is firmly installed. At the same time, a safety buckle 94 is designed on the back of the hanging slot to prevent the hook from accidentally separating from the hanging slot, thereby improving the safety of the cabinet door. When the user needs to remove the cabinet door, he only needs to pry open the safety buckle to make it out of the range of the hanging slot, and then lift the cabinet door upward to separate the hook from the hanging slot.

[0041] Unlike traditional lifting wall cabinets, the cabinet doors installed at the front end of the cabinet in this case are divided into two parts, the upper part is a fixed cabinet door, and the lower part is a movable cabinet door connected to this mechanism. This mechanism needs to push the movable cabinet door outward while the wall cabinet is lowered, so that it leaves the plane of the fixed cabinet door. Then, as the wall cabinet descends, the movable cabinet door is lifted upward so that the movable cabinet door covers the outside of the fixed cabinet door, thereby opening the movable cabinet door space that is originally closed, making it easier for users to take things from the top layer of the wall cabinet. Therefore, compared with traditional technology, the cabinet installed with this mechanism only needs to lower its wall cabinet part a lower distance to achieve the removal and placement of double-layer items in the wall cabinet. There is no need to completely lower the wall cabinet to the bottom, which affects the placement of items on the cabinet surface. While making it convenient for users to take and place items in the wall cabinet, it does not affect the use of the bottom cabinet, greatly improving the utilization rate of space, so it can be widely promoted and used.

[0042] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements shall fall within the scope of the present invention as claimed.
