Description
Technical Field
[0001] This utility model relates to the field of kitchen furniture technology, specifically to a barrier-free kitchen wall cabinet pull-out device. Background Technology
[0002] In the field of kitchen design, wall cabinets, as core facilities for storing tableware, food, and kitchen utensils, directly impact user experience due to their ease of use. Traditional wall cabinets generally adopt a fixed-height installation mode, with a cabinet depth typically 50-60cm and an installation height of 1.6-1.8m from the ground. This design presents significant usage obstacles for the elderly, disabled, or those of short stature: users need to tiptoe, lean out, or use assistive tools to reach items deep inside the cabinet, which is not only cumbersome but also poses safety hazards such as items falling and loss of balance.
[0003] While some height-adjustable wall cabinet designs exist in the current technology, these solutions are generally complex in structure. For example, designs using gear racks or electric lifting mechanisms require complex components such as motors, steel wires, and controllers, which increases production costs by 30%-50% compared to traditional wall cabinets. They are also difficult to install and maintain, and are cumbersome and costly to operate, making it difficult to promote and apply them widely in the market.
[0004] Chinese Patent Publication No. CN208064842U discloses an intelligent kitchen lifting cabinet that requires a motor, a steel wire system, and a controller. It uses an electric lifting mechanism to move the cabinet up and down. However, this design relies on electric drive, which not only increases the complexity of installation and maintenance, but also has the limitation of not being usable during power outages. The operation method is not intuitive, and the rope components are prone to wear, posing certain safety hazards.
[0005] Existing solutions mostly only achieve vertical lifting function, which cannot meet the combined needs of "horizontal pull-out + angle rotation" for retrieving items, and it is still difficult to efficiently store and retrieve items deep inside the cabinet; moreover, they lack a multi-level height adjustment mechanism, which cannot adapt to the usage scenarios of users of different heights.
[0006] In summary, existing kitchen wall cabinet technology has significant shortcomings in terms of accessibility design: the fixed height structure makes it inconvenient to retrieve items, and the adjustable solution is difficult to promote due to its complex structure, high cost and reliability issues. There is an urgent need for an accessible wall cabinet pull-out device that is simple in structure, easy to operate and suitable for multiple user groups. Utility Model Content
[0007] Therefore, this utility model provides a barrier-free kitchen wall cabinet pull-out device to solve the problems of existing wall cabinets being unable to be moved to retrieve items and inconvenient storage and retrieval of items deep inside.
[0008] To achieve the above objectives, this application provides the following technical solution:
[0009] A barrier-free kitchen wall cabinet pull-out device includes a cabinet body, and also includes: a guide rail assembly, a rotating groove, a limiting block, a connecting rod assembly, and a handle;
[0010] The guide rail assembly is located on one side of the cabinet and includes at least two parallel horizontal slide rails and one vertical slide rail. The horizontal slide rails extend horizontally and are located at different heights. The vertical slide rails extend vertically and communicate with the horizontal slide rails to form a multi-level height-adjustable linkage path.
[0011] The rotating grooves are respectively disposed on the upper and lower sides of the middle of each of the transverse sliding grooves. The rotating grooves are fan-shaped, and the fan shape is part of the circumcircle of the cross section of the limiting block and the central angle of the fan shape is an acute angle. The two rotating grooves are symmetrically distributed with respect to the center of the circumcircle.
[0012] One end of the limiting block is slidably disposed in the guide rail assembly, and the limiting block can only rotate at the rotating groove;
[0013] The linkage group includes a four-bar linkage mechanism and an elastic reset device. The upper end of the four-bar linkage mechanism is slidably connected to a third slide groove parallel to the transverse slide groove, and the lower end is connected to the top of the cabinet. The elastic reset device is connected to the four-bar linkage mechanism to retract and reset the four-bar linkage mechanism.
[0014] A handle, which is located on the outer surface of the cabinet, is used to receive the pulling force applied by the user to control the translation, lifting and rotating movements of the cabinet.
[0015] Furthermore, the four-bar linkage includes an upper connecting part, a lower connecting part, four first connecting rods, and two second connecting rods. The upper connecting part is slidably connected to the third sliding groove via a third slider. The lower connecting part is located on the top of the cabinet. The four first connecting rods are arranged in two groups in a cross-symmetrical manner. The upper ends of the two first connecting rods in the first group are hinged to the upper connecting part. The lower ends of the two first connecting rods in the second group are hinged to the lower connecting part, and their upper ends are hinged to the lower ends of the two first connecting rods in the first group to form a floating hinge point. The two second connecting rods are arranged parallel between the two groups of first connecting rods, with one end hinged to the floating hinge point and the other end hinged to the first connecting rod of the adjacent group, forming a deformable parallelogram linkage mechanism.
[0016] Furthermore, the lower connecting part is hinged to the top of the cabinet via a second pivot. The second pivot is located inside the top of the cabinet and at the bottom of the lower connecting part, so that the four-bar linkage mechanism and the cabinet form a rotatable connection structure.
[0017] Furthermore, the limiting block is square.
[0018] Furthermore, the number of the transverse grooves is three.
[0019] Furthermore, the vertical spacing between adjacent transverse grooves is 30mm-50mm.
[0020] Furthermore, each of the transverse sliding grooves is provided with a transverse guide rail, and each of the transverse guide rails is slidably provided with a first slider. A through groove is provided between adjacent transverse sliding grooves, and the through groove communicates with the longitudinal sliding groove. A longitudinal guide rail is installed on the outward side of each of the first sliders. The longitudinal guide rail can slide laterally along the through groove. A second slider is slidably provided on the longitudinal guide rail, and the second slider is connected to the limiting block through a first rotating shaft.
[0021] Furthermore, the cabinet can be rotated by a predetermined angle of 15°-30°.
[0022] Furthermore, the elastic reset device is a spring, and there are two springs. The two springs are symmetrically arranged and their tops are respectively fixed to the upper connecting part, and their bottoms are fixed to the top of the cabinet.
[0023] Compared with the prior art, the present invention has at least the following beneficial effects:
[0024] 1. This application adopts a multi-level height-adjustable guide rail group design with multi-level horizontal slide rails and vertical slide rails linked together. It does not require electric drive. It can switch to different heights of the horizontal slide rails by simply sliding the limit block vertically in the vertical slide rail, forming a multi-level height adjustment position to adapt to different usage scenarios such as standing and sitting postures, meet the needs of barrier-free use, and has a simple structure and lower cost.
[0025] 2. This application features a "horizontal sliding track + rotating track" design. The horizontal sliding track enables the cabinet to be pulled out horizontally, overcoming space limitations. Simultaneously, a rotating track is located in the middle of the horizontal sliding track. When the limiting block slides into the rotating track, the cabinet can rotate at a predetermined angle, ensuring that items deep inside are directly facing the user for easy viewing and retrieval. This design achieves a combined "horizontal pull-out + directional rotation" motion through purely mechanical means. Operation can be completed using only a handle, significantly reducing the difficulty of storage and retrieval, and is superior to existing single-function wall cabinet structures.
[0026] 3. The four-bar linkage in the linkage group is slidably connected to the third slide rail on the ceiling, achieving stable extension and retraction as the cabinet moves horizontally. The elastic reset device provides automatic lifting force, eliminating the need for manual lifting. The cooperation between the limit block and the guide rail group achieves precise switching between "vertical locking - horizontal sliding - rotational positioning" through mechanical constraints, avoiding the risk of failure of the electric system. At the same time, it is not dependent on electricity and can still be used normally during power outages, resulting in lower maintenance costs and higher reliability.
[0027] 4. Users only need to pull the handle to control the cabinet to rise and fall in the longitudinal slide, slide horizontally in the transverse slide, and rotate in the rotary slide. All actions are naturally connected through the mechanical structure, without the need for complicated operation logic. It is especially suitable for users with weak physical strength or mobility difficulties, truly achieving "barrier-free operation".

[0038] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.
[0039] Example 1
[0040] like Figures 1 to 6 As shown, a barrier-free kitchen wall cabinet pull-out device includes a cabinet body 1, a guide rail assembly, a rotating groove 3, a limiting block 4, a connecting rod assembly, and a handle 8.
[0041] Cabinet 1 is used to store kitchen utensils.
[0042] The guide rail assembly is located on one side of the cabinet 1, including at least two parallel horizontal slide rails 21 and one vertical slide rail 22. The horizontal slide rails 21 extend horizontally and are located at different heights. The vertical slide rail 22 extends vertically and connects with the horizontal slide rails 21 to form a multi-level height-adjustable linkage path. The vertical slide rail 22 is located to the left or right of the horizontal slide rails 21. Preferably, there are three horizontal slide rails 21 and the vertical spacing between adjacent horizontal slide rails 21 is 30mm-50mm.
[0043] Rotating grooves 3 are respectively disposed on the upper and lower sides of the middle of each transverse slide groove 21. The rotating grooves 3 are fan-shaped, and the fan shape is part of the circumcircle of the cross-section of the limiting block 4, with the central angle of the fan shape being an acute angle. The two rotating grooves 3 are symmetrically distributed with respect to the center of the circumcircle. The rotating groove 3 located above the transverse slide groove 21 is relatively forward than the rotating groove 3 located below the transverse slide groove 21. This ensures that when the limiting block 4 is in this position, the front end of the cabinet 1 (referring to the end with the handle 8) can swing downward at a certain angle. Preferably, the cabinet 1 can rotate at a predetermined angle of 15°-30°.
[0044] One end of the limiting block 4 is fixed in the wall, and the other end extends into the guide rail assembly and can slide relative to the horizontal slide groove 21 or the vertical slide groove 22. The limiting block 4 can only rotate at the rotating groove 3. Preferably, the limiting block 4 is square, and its edge slides against the edge of the horizontal slide groove 21 or the vertical slide groove 22. This ensures that the front end of the cabinet 1 can swing downward only when the limiting block 4 is located at the rotating groove 3 (i.e., the limiting block 4 rotates relative to the cabinet 1 at the rotating groove 3).
[0045] The linkage assembly includes a four-bar linkage and an elastic reset device. The upper end of the four-bar linkage is slidably connected to a third slide groove 6 parallel to the transverse slide groove 21, and the lower end is connected to the top of the cabinet 1. The elastic reset device is connected to the four-bar linkage to retract and reset the four-bar linkage.
[0046] Handle 8 is provided on the outer surface of cabinet 1 and is used to receive the pulling force applied by the user to control the translation, lifting and rotating movements of cabinet 1.
[0047] The working principle of this embodiment is as follows:
[0048] Taking the longitudinal slide 22 located on the right side of the transverse slide 21 as an example, push the handle 8 to the left to make the cabinet 1 slide to the left. When the limiting block 4 is located in the longitudinal slide 22, the user can pull the handle 8 on the outer surface of the cabinet 1 to make the limiting block 4 slide along the longitudinal slide 22, pull down or push the cabinet 1, and the four-bar linkage extends (expands) or retracts to adjust the cabinet 1 to the target height of the transverse slide 21. Then, pull the cabinet 1 horizontally along the transverse slide 21 to complete the height adjustment. When the limiting block 4 is located in the rotating groove 3 in the middle of the transverse slide 21, the cabinet 1 can rotate 10°-30° to retrieve items deep inside. After retrieving the items, reverse the operation to make the limiting block 4 return to the transverse slide 21. Push the cabinet 1 horizontally to make the limiting block 4 slide into the longitudinal slide 22, so as to prevent the cabinet 1 from tilting or rotating unexpectedly due to uneven weight of the items inside. The vertical slide 22 and the multi-level horizontal slide 21 work together to achieve barrier-free height adjustment, adapting to different user needs. It does not require electric drive and the pure mechanical structure is more reliable. The fan-shaped rotating slide 3 is designed for easy operation and solves the problem of storing and retrieving items deep inside. The four-bar linkage mechanism works with the third slide 6 to ensure smooth movement of the cabinet. The elastic reset device reduces physical exertion. The overall structure is simple and low-cost. The pull-out device in this application lowers the threshold for use and is suitable for widespread promotion.
[0049] Example 2
[0050] like Figure 5The second embodiment is basically the same as the first embodiment, with the main difference being that the four-bar linkage includes an upper connecting part 51, a lower connecting part 52, four first connecting rods 53 and two second connecting rods 54. The upper connecting part 51 is slidably connected to the third sliding groove 6 through a third slider 511. The lower connecting part 52 is located on the top of the cabinet 1. The four first connecting rods 53 are arranged in two groups in a cross-symmetrical manner. The upper ends of the two first connecting rods 53 in the first group are hinged to the upper connecting part 51. The lower ends of the two first connecting rods 53 in the second group are hinged to the lower connecting part 52, and their upper ends are hinged to the lower ends of the two first connecting rods 53 in the first group to form a floating hinge point. The two second connecting rods 54 are arranged in parallel between the two groups of first connecting rods 53. One end of one of them is hinged to the floating hinge point, and the other end is hinged to the first connecting rod 53 of the adjacent group, forming a deformable parallelogram linkage mechanism.
[0051] The lower connecting part 52 is hinged to the top of the cabinet 1 via the second rotating shaft 7. The second rotating shaft 7 is located inside the top of the cabinet 1 and at the bottom of the lower connecting part 52, so that the four-bar linkage mechanism and the cabinet 1 form a rotatable connection structure.
[0052] The working principle of this embodiment is as follows:
[0053] The four-bar linkage mechanism forms a floating hinge point through two sets of cross-symmetrical first links 53, which, together with the parallel second links 54, constitute a deformable parallelogram linkage mechanism. This improves the stability and load-bearing capacity of the cabinet 1 during horizontal movement and rotation. Simultaneously, the lower connecting part 52 connects to the second pivot 7 of the cabinet 1, allowing the four-bar linkage mechanism to adaptively adjust its angle as the cabinet 1 rotates, reducing motion interference and further optimizing operational smoothness. This better meets the needs of people with mobility impairments for smooth cabinet movement and flexible item retrieval. By setting up the four-bar linkage mechanism and the elastic reset device, the elastic reset device can offset part of the weight of the items stored inside the cabinet 1, making height adjustment easier. The third slide 6 and the third slider 511 ensure that the linkage group moves horizontally synchronously with the cabinet 1.
[0054] Example 3
[0055] like Figure 6The third embodiment is basically the same as the second embodiment, with the main difference being: each transverse slide groove 21 is provided with a transverse guide rail 211, and each transverse guide rail 211 is slidably provided with a first slider 212. A through groove 213 is provided between adjacent transverse slide grooves 21, and the through groove 213 is connected to the longitudinal slide groove 22. A longitudinal guide rail 214 is installed on the outward side of each first slider 212. The longitudinal guide rail 214 can slide laterally along the through groove 213. A second slider 215 is slidably provided on the longitudinal guide rail 214. The sliding of the second slider 215 along the longitudinal guide rail 214 is restricted by the linkage path. It can only slide along the longitudinal guide rail 214 when the second slider 215 is in the longitudinal slide groove 22. The second slider 215 is connected to the limiting block 4 through the first rotating shaft.
[0056] In this embodiment, when the user adjusts the height of the cabinet 1 by pushing the handle 8, the first slider 212 slides on the horizontal guide rail 211, and the vertical guide rail 214 slides along the through groove 213 with the first slider 212. When the vertical guide rail 214 slides into the vertical slide groove 22, the second slider 215 can slide along the vertical guide rail 214. At this time, the limiting block 4 moves synchronously with the second slider 215 until the limiting block 4 slides into the horizontal slide groove 21 at the target height. Then, the handle 8 is pulled to make the second slider 215 and the limiting block 4 slide into the horizontal slide groove 21, thus completing the height adjustment. When the cabinet 1 is pushed and pulled horizontally, the first slider 212 slides along the horizontal guide rail 211, and the limiting block 4 and the second slider 215 cooperate with the horizontal slide groove 21 to achieve smooth movement. When rotating to pick up items, the limiting block 4 rotates relative to the second slider 215 through the first rotating shaft to ensure that the cabinet 1 can rotate relative to the limiting block 4. While retaining all the advantages of Embodiment 2, the cooperation of the transverse guide rail 211, the first slider 212, the through groove 213 and the longitudinal guide rail 214 makes the longitudinal movement during height adjustment smoother and avoids jamming. The combination design of the second slider 215 and the first rotating shaft further optimizes the linkage accuracy between the limit block 4 and the cabinet 1, reduces structural interference during rotation and horizontal movement, and improves the load-bearing stability and smoothness of the overall mechanism, making it more suitable for the needs of people with mobility impairments for labor-saving operation and structural reliability.
[0057] Example 4
[0058] like Figure 5 The fourth embodiment is basically the same as the third embodiment, the main difference being that the elastic reset device is a spring 9. Preferably, there are two springs 9, which are symmetrically arranged and their tops are fixed to the upper connecting part 51, and their bottoms are fixed to the top of the cabinet 1.
[0059] In this embodiment, when the cabinet 1 rises and falls along the longitudinal slide 22, two symmetrically arranged springs 9 are simultaneously subjected to force to assist the four-bar linkage mechanism in driving the cabinet 1 to move smoothly. The symmetrical layout makes the elastic tension more balanced, avoiding the cabinet 1 from tilting due to uneven force during the rising and falling process, thus improving the stability of movement. At the same time, the double spring design ensures that the cabinet is more effortless and responds more quickly when it rises automatically in the longitudinal slide, further optimizing the operating experience for people with mobility impairments. Moreover, the spring structure is simple, low in cost, and easy to maintain and replace.
[0060] The technical features of the above embodiments can be combined in any way (as long as there is no contradiction in the combination of these technical features). For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described; these embodiments not explicitly written should also be considered to be within the scope of this specification.
