Description

Technical Field

[0001] This utility model relates to the field of home customization and furniture design technology, specifically to a cuttable two-way pull-out slide rail device and a home customization assembly drawer using the same. Background Technology

[0002] Whole-house custom furniture is a user-centric model that fully customizes all furniture for the entire house. It coordinates the relationship between furniture and interior decoration through design, and utilizes factory production to achieve style unity and craftsmanship. It encompasses vertical alliances (home decoration companies collaborating with manufacturers to customize materials) and horizontal alliances (integrating the furniture, home appliance, and other industry chains to form a one-stop service). Designers are involved throughout the process to ensure a consistent home style. This model originated from the industrialization of home decoration and is gradually replacing traditional decoration methods. In the application of customized home design, side-mounted drawers with sliding rails are common storage products. While they allow for easy access, they waste space, require drawer fronts and handles, are unsightly when the rails are exposed, and cannot be cut to length or pulled out in both directions.

[0003] In the prior art, Chinese invention patent with publication number CN101530263A discloses a bidirectional pull-out slide rail, including two fixed rails, two slide rails fixed to both sides of the shelf and capable of bidirectional pull-out along the fixed rails, and a locking mechanism. The locking mechanism consists of a pair of locking members arranged in opposite directions at both ends of the same side of the bidirectional pull-out slide rail. Each locking member includes a stop block installed on the fixed rail, a fixed seat fixedly installed on the slide rail, a locking hook with an operating handle, a locking pin, and a torsion spring. The locking hook is movably mounted on the fixed seat through the locking pin, and its lower end is hooked onto the stop block. The torsion spring is sleeved on the locking pin, with one end fixed to the fixed seat and the other end fixed to the operating handle. The two-way pull-out slide rail of this invention patent is commonly used in iron drawer cabinets in factories or laboratories. It has the disadvantages of having many parts, complex structure, high manufacturing and installation costs, inconvenient on-site installation, and poor compatibility with the main frame of the drawer made of wood. It is not suitable for application scenarios such as customized home decoration and rapid renovation of old houses where the installation size needs to be adjusted on-site.

[0004] In addition, Chinese utility model patent CN213306021U discloses a bidirectional pull-out slide rail, which can achieve bidirectional pull-out and lock and maintain the extended state when the slide rail is pulled out to a designated position. It includes a first track, a second track, and a ball retainer. A front locking plate and a rear locking plate are installed on the first track. The locking plate includes an unlocking part, a snap-fit ​​part, a guide part, and an installation part. An elastic component is also provided between the locking plate and the first track. The front part of the second track has a snap-fit ​​block 1 corresponding to the snap-fit ​​part of the rear locking plate, and the rear part of the second track has a snap-fit ​​block 2 corresponding to the snap-fit ​​part of the front locking plate. The snap-fit ​​block 1 and the snap-fit ​​block 2 are located at different heights. When the slide rail is opened forward, the front locking plate is located on the movement path of the snap-fit ​​block 2. When the slide rail is opened backward, the rear locking plate is located on the movement path of the snap-fit ​​block 1. The locking of the first track and the second track is achieved by the cooperation of the snap-fit ​​block 1, the snap-fit ​​block 2, and the snap-fit ​​part. Both rails 1 and 2 are stamped sheet metal parts with fixed transverse lengths and non-cuttable longitudinal stamping structures. This utility model patent's bidirectional pull-out slide rail still suffers from drawbacks such as numerous parts, complex structure, high manufacturing and installation costs, and inconvenient on-site installation. Therefore, it is not suitable for applications requiring on-site adjustments for customized home renovations or rapid remodeling of old houses.

[0005] Furthermore, the whole-house custom furniture industry faces multiple challenges in the on-site construction phase, leading to significant delays in the construction period. The specific manifestations and reasons are as follows:

[0006] I. Issues related to the integration of design and production:

[0007] High error rate in order splitting: Errors in size or structural calculations lead to mismatched parts, requiring rework and directly affecting the installation schedule;

[0008] Missing or incorrect parts: Manual sorting is prone to missing parts. If missing or incorrect parts are found during installation, they need to be reissued, which will extend the construction period.

[0009] Installation diagrams do not match the actual product: Detailed installation instructions are lacking or the drawings are not standardized, requiring workers to make adjustments or even redo the work on-site.

[0010] II. Weaknesses in Supply Chain and Resource Management:

[0011] Material supply delays: Untimely delivery or substandard quality of materials such as boards and installation accessories leads to construction stagnation;

[0012] Shortage of skilled workers: Skilled installers are highly mobile, and when coordination is not smooth, it is necessary to wait for reassignment;

[0013] Low utilization rate of CNC equipment and automated production equipment: Reliance on operation by experienced technicians, and the efficiency of automated production is not fully realized;

[0014] Third, a short on-site construction period is required:

[0015] Difficulties in coordinating multiple job types: increased rework or waiting time;

[0016] IV. Systemic Pain Points in the Industry:

[0017] Lack of standardization: Customized products lack unified production standards, rely on manual experience, and have a high error rate.

[0018] Currently, the publicly disclosed patented technologies mentioned above are insufficient to simultaneously address most of the technical challenges in the overall home furnishing customization industry. Utility Model Content

[0024] Furthermore, the locking end cap is also used to cooperate with other locking end caps to lock the drawer when it is pushed back to its original position after the drawer has been reset in the cabinet / counter; that is, when the drawer is pushed back to its original position after the drawer has been reset in the cabinet / counter, the first sliding locking mechanism of the first locking end cap and the second sliding locking mechanism of the third locking end cap are elastically engaged, and the first sliding locking mechanism of the second locking end cap and the second sliding locking mechanism of the fourth locking end cap are elastically engaged.

[0025] Furthermore, the ball assembly includes a plurality of steel balls and at least one strip-shaped ball holder for embedding each steel ball; the strip-shaped ball holder is fixedly mounted on the inner slide rail.

[0026] Furthermore, the first sliding locking mechanism includes a spring and a top ball connected to one end of the spring; both the first locking end cover and the second locking end cover are provided with a first mounting cavity; the other end of the spring presses against an inner wall of the first mounting cavity, and a first through hole is opened in the other inner wall. When the first sliding locking mechanism and the corresponding second sliding locking mechanism are elastically engaged, the top ball elastically protrudes out of the first through hole.

[0027] Furthermore, the second sliding locking mechanism is a locking notch provided on the third or fourth locking end cover for locking the top ball.

[0028] Furthermore, the guide groove of the outer slide rail is located on one longitudinal side of the outer slide rail, and the bottom surface of the guide groove of the outer slide rail is parallel to the side surface on the other longitudinal side of the outer slide rail.

[0029] An extension plate is provided on the other side of the longitudinal direction of the outer slide rail, facing away from the guide groove. The extension plate is used to support the bottom plate of a drawer.

[0030] This utility model discloses a customizable assembled drawer for home use, employing the cuttable bidirectional pull-out slide rail device as described in any of the preceding claims. The drawer is designed for bidirectional pull-out within a cabinet / counter.

[0046] Example 1

[0047] like Figures 1-7 As shown:

[0048] This embodiment proposes a cutable bidirectional pull-out slide rail device as a slide rail device for supporting a drawer between a cabinet / counter 100 and a drawer that is pulled out bidirectionally. The cutable bidirectional pull-out slide rail device includes an inner slide rail 1 and an outer slide rail 2 that slide and fit together. A ball bearing assembly 9 is provided between the guide groove walls of the inner slide rail 1 and the outer slide rail 2. Both the inner slide rail 1 and the outer slide rail 2 are made of aluminum. Two locking end caps are detachably installed at both ends of the inner slide rail 1, namely a first locking end cap 11 and a second locking end cap 12. Similarly, two locking end caps are detachably installed at both ends of the outer slide rail 2, namely a third locking end cap 21 and a fourth locking end cap 22. Cover 22; the first locking end cover 11 and the second locking end cover 12 are each provided with a first sliding locking mechanism, and the third locking end cover 21 and the fourth locking end cover 22 are each provided with a second sliding locking mechanism; when the cuttable bidirectional pull-out slide rail device is pulled out from the forward direction and is in a limit extension state, the first sliding locking mechanism of the second locking end cover 12 and the second sliding locking mechanism of the third locking end cover 21 are elastically engaged; when the cuttable bidirectional pull-out slide rail device is pulled out from the reverse direction and is in another limit extension state, the first sliding locking mechanism of the first locking end cover 11 and the second sliding locking mechanism of the fourth locking end cover 22 are elastically engaged.

[0049] The locking end cap is used to protect the end of the corresponding slide rail, and also to cooperate with other locking end caps to lock the drawer back when it is pulled out and in its maximum extension position.

[0050] Ideally, the structural projection outer contour of a first cross-section at the left end of the outer slide rail 2, the structural projection outer contour of a second cross-section at the middle of the outer slide rail 2, and the structural projection outer contour of a third cross-section at the right end of the outer slide rail 2 are the same, and the first cross-section, the second cross-section, and the third cross-section are all perpendicular to the virtual center line of the length direction of the outer slide rail 2; the structural projection outer contour of a fourth cross-section at the left end of the inner slide rail 1, the structural projection outer contour of a fifth cross-section at the middle of the inner slide rail 1, and the structural projection outer contour of a sixth cross-section at the right end of the inner slide rail 1 are the same, and the fourth cross-section, the fifth cross-section, and the sixth cross-section are all perpendicular to the virtual center line of the length direction of the inner slide rail 1.

[0051] Optimally, the locking end cover is also used to cooperate with other locking end covers to lock the drawer when it is pushed back to its original position after the drawer is reset in the cabinet / counter 100; that is, when the drawer is pushed back to its original position after the drawer is reset in the cabinet / counter 100, the first sliding locking mechanism of the first locking end cover 11 and the second sliding locking mechanism of the third locking end cover 21 are elastically engaged, and the first sliding locking mechanism of the second locking end cover 12 and the second sliding locking mechanism of the fourth locking end cover 22 are elastically engaged.

[0052] As an optional optimized implementation, the ball assembly 9 includes multiple steel balls and at least one strip ball holder for embedding each steel ball to achieve the slide rail limiting and sliding functions; the strip ball holder is fixedly installed on the inner slide rail 1; furthermore, steel column bars can be used to replace the steel balls, which can prevent the steel balls from colliding and generating noise, and at the same time facilitate assembly; in addition, the strip ball holder can be cut according to the length of the guide rail.

[0053] As an optional optimized implementation, the first sliding locking mechanism includes a spring member 6 and a top bead 7 connected to one end of the spring member 6; both the first locking end cover 11 and the second locking end cover 12 are provided with a first mounting cavity; the other end of the spring member 6 presses against one inner wall of the first mounting cavity, and a first through hole is opened in the other inner wall. When the first sliding locking mechanism and the corresponding second sliding locking mechanism are elastically engaged, the top bead 7 elastically protrudes out of the first through hole.

[0054] Further optimized, the second sliding locking mechanism is a locking notch 8 (which can be optimized as a recessed structure) for engaging the top ball 7, located on the third locking end cover 21 or the fourth locking end cover 22. Specifically, when the slide rail is closed, the top ball 7 of the locking end cover corresponding to the inner slide rail 1 is pushed into the recessed structure of the locking end cover corresponding to the outer slide rail 2 by the spring member 6, thereby realizing the sliding locking function. Thus, by simply installing the corresponding locking end covers at both ends of the inner slide rail 1 and the outer slide rail 2, the limit locking and bidirectional pull-out functions of the drawer slide rail can be easily realized. This greatly facilitates maintenance or replacement of parts. The slide rail device in this embodiment also simplifies the complex functional structure of the existing guide rail, improves its complex structure design, and transfers the relevant simple functional structure to the locking end cover. Thus, the inner slide rail 1 and outer slide rail 2, which account for most of the overall material weight, can be mass-produced by an aluminum profile extrusion press and can also be cut according to the specific dimensions of the installation site. This solves the industry pain point of home customization, reduces production and installation costs, and plays an important role in popularizing cost-saving and efficiency-enhancing home customization decoration to thousands of households.

[0055] Further optimized, the guide groove of the outer slide rail 2 is located on one longitudinal side of the outer slide rail 2, and the bottom surface of the guide groove of the outer slide rail 2 is parallel to the side surface of the other longitudinal side of the outer slide rail 2.

[0056] Further optimized, an extension plate 23 is provided on the other side of the longitudinal direction of the outer slide rail 2, facing away from the guide groove. The extension plate 23 is used to support a drawer bottom plate 3. This increases the structural strength of the outer slide rail 2, improves the load-bearing capacity of the outer slide rail 2 on the drawer bottom plate 3, and facilitates the quick on-site installation of a drawer that can be pulled out in both directions.

[0057] Preferably, the drawer bottom plate 3 is a wood board, a wood-based engineered wood panel, or a veneered honeycomb panel.

[0058] Specifically, an extension plate 23 and a lower flange portion respectively extend from a side surface of the bottom of the outer slide rail 2 facing the drawer bottom plate 3 and another side surface of the bottom of the outer slide rail 2 facing away from the drawer bottom plate 3, and an upper flange portion extends from another side surface of the top of the metal profile member structure facing away from the laminate; one inner slide rail 1 is correspondingly mounted on a first middle side surface of the outer slide rail 2 facing away from the drawer bottom plate 3, and the first middle side surface (that is, the groove bottom surface of the guide groove of the outer slide rail 2 on the left side of the drawer) is located between the lower flange portion and the upper flange portion of the outer slide rail 2 on the left side of the drawer; another inner slide rail 1 is correspondingly mounted on a second middle side surface of the outer slide rail 2 on the right side facing away from the drawer bottom plate 3, and the second middle side surface (that is, the groove bottom surface of the guide groove of the outer slide rail 2 on the right side of the drawer) is located between the lower flange portion and the upper flange portion of the outer slide rail 2 on the right side of the drawer; the lower flange portion cooperates with the upper flange portion to be supported and guided by the corresponding inner slide rail 1; the extension plate 23 is configured to carry the edge portion of the drawer bottom plate 3.

[0059] Further, as Figure 2 shown, the outer slide rail 2 on the left side of the drawer is sequentially divided into a first upper half portion and a first lower half portion in the up-down direction, and the outer slide rail 2 on the left side of the drawer is sequentially divided into a first left side portion and a first right portion in the left-right direction (the length direction of the outer slide rail 2 is the Figure 2 front-back direction), when viewed from the front toward the end of the outer slide rail 2, the cross-sectional structure of the first upper half portion and the cross-sectional structure of the first lower half portion are respectively in a reversed L shape and an inverted T shape, that is, the cross-sectional structure of the first left side portion and the cross-sectional structure of the first right portion are respectively in a ] shape and an L shape;

[0060] the outer slide rail 2 on the right side of the drawer is sequentially divided into a second upper half portion and a second lower half portion in the up-down direction, and the outer slide rail 2 on the right side of the drawer is sequentially divided into a second left side portion and a second right portion in the left-right direction (the length direction of the outer slide rail 2 is the Figure 2 front-back direction), when viewed from the rear toward the end of the outer slide rail 2, the cross-sectional structure of the second upper half portion and the cross-sectional structure of the second lower half portion are respectively in a reversed L shape and an inverted T shape, that is, the cross-sectional structure of the second left side portion and the cross-sectional structure of the second right portion are respectively in a ] shape and an L shape.

[0061] According to further optimization, the inner groove wall of the guide groove of the inner slide rail 1 and / or the inner groove wall of the guide groove of the outer slide rail 2 is provided with a ball groove.

[0062] According to further optimization, the surfaces of the inner slide rail 1 and the outer slide rail 2 are further provided with an aluminum oxide anticorrosive layer, which is not only decorative, but also can prevent the problem of surface layer falling off of the slide rail during the drawing process.

[0063] As Figure 4As shown, as an optional optimized implementation, the locking end cap installed at the end of the inner slide rail 1 is cuboid in shape and has an inner cavity. The inner cavity is open on one side facing the end face of the inner slide rail 1, and the spring member 6 is arranged perpendicular to the length direction of the inner slide rail 1. The upper part of the inner cavity of the inner slide rail 1 is provided with a first screw fixing structure, which is screwed into a screw for threaded connection with the end of the inner slide rail 1. The lower part of the inner cavity of the inner slide rail 1 is provided with a second screw fixing structure, which is screwed into another screw for threaded connection with the end of the inner slide rail 1. The inner wall of the inner cavity pressed by the other end of the spring member 6 is provided with a fixing step structure for installing and fixing the other end of the spring member 6.

[0064] like Figure 5 As shown, as an optional optimized implementation, the locking end cap installed at the end of the outer slide rail 2, when viewed from the end face of the outer slide rail 2, has a U-shaped structure rotated 90 degrees counterclockwise. A third screw fixing structure is provided at the top of this U-shaped structure, into which a third screw is screwed for threaded connection with the end of the outer slide rail 2. A fourth screw fixing structure is provided at the bottom of this U-shaped structure, into which a fourth screw is screwed for threaded connection with the end of the outer slide rail 2. The snap-fit ​​notch 8 is located on one side of the middle of the U-shaped structure, parallel to the length direction of the outer slide rail 2. This side also has a clearance notch to avoid the fifth self-tapping screw, thus preventing interference and making the installation space more compact. Figure 5 As shown, the fifth self-tapping screw is used to fix the end of the outer slide rail 2 to one end face of the drawer front panel 4.

[0065] Example 2

[0066] like Figure 1 , Figure 6 , Figure 7 As shown:

[0067] This embodiment proposes a customizable assembled drawer for home use, employing the cuttable bidirectional pull-out slide rail device as described in any of the technical solutions of Embodiment 1. The drawer is designed for bidirectional pulling within a cabinet / counter 100. The cabinet / counter 100 has two opposing inner cavity side panels equipped with the inner slide rail 1 of the cuttable bidirectional pull-out slide rail device. The drawer includes a drawer bottom plate 3, a drawer front baffle 4, a drawer rear baffle 5, and two outer slide rails 2 of the cuttable bidirectional pull-out slide rail device; one outer slide rail 2 serves as the drawer left baffle, and the other outer slide rail 2 serves as the drawer right baffle.

[0068] As an optional optimized implementation, the drawer bottom plate 3, the drawer front baffle 4, and the drawer back baffle 5 are all made of wood, wood-based engineered wood, or veneered honeycomb board.

[0069] Ideally, the outer slide rail 2 serving as the left drawer baffle is the first outer slide rail, and the outer slide rail 2 serving as the right drawer baffle is the second outer slide rail. The two ends of the first outer slide rail are respectively connected and fixed to the left end face of the front drawer baffle 4 and the left end face of the rear drawer baffle 5 using self-tapping screws. The two ends of the second outer slide rail are respectively connected and fixed to the right end face of the front drawer baffle 4 and the right end face of the rear drawer baffle 5 using self-tapping screws. In this way, the drilling action of the self-tapping screws on the aluminum profile can be used to achieve quick installation without the need for precise stamping in the factory.

[0070] Specifically, the drawer bottom plate 3 (i.e., shelf) is connected to the drawer front baffle 4 (i.e., front stop) and the drawer rear baffle 5 (i.e., rear stop) so that it can be connected to the two external slide rails 2 later.

[0071] The installation process of the customized modular drawer in this embodiment is as follows:

[0072] On-site, the drawer bottom plate 3 (i.e., shelf) is connected and assembled with the drawer front baffle 4 (i.e., front baffle) and the drawer rear baffle 5 (i.e., rear baffle). Then, one end of the two outer slide rails 2 is aligned with the front and rear baffles and connected with self-tapping screws. The other end of the two outer slide rails 2 is connected in the same way, thereby realizing the assembly of the outer slide rails 2 with the shelf and the front and rear baffles.

[0073] Place the ball assembly 9 into the ball groove of the inner slide rail 1, and then insert the inner slide rail 1 and the ball assembly 9 together into the outer slide rail 2 along the ball groove of the outer slide rail 2.

[0074] Place the corresponding locking end caps on the cross-sections at both ends of the corresponding slide rail;

[0075] The corresponding locking end caps are fixed by screwing self-tapping screws into the pre-drilled holes at both ends of the corresponding slide rail.

[0076] The spring 6 pushes the top ball 7 out from the first through hole (i.e., end cap hole) of the corresponding inner slide rail 1;

[0077] The top bead 7 is pushed into the locking notch 8 (or recess) of the corresponding outer slide rail 2 by the spring member 6, thereby realizing the sliding locking function; after the drawer is installed, the trolley or other cabinets that need to be pulled out in both directions will be more convenient to take out items, the cost will be lower, the installation efficiency will be higher, and the maintenance will be easier.

[0078] The customizable, modular drawer with a cutable two-way pull-out slide rail device in this embodiment also has the following advantages:

[0079] ① The baffle strip is connected to the shelf, which effectively enhances the load-bearing capacity of the shelf, prevents items from falling during the pull-out process, and facilitates the pull-out process;

[0080] ② Both the inner slide rail 1 and the outer slide rail 2 are extruded and integrally formed aluminum profiles, which can not only be cut according to the required length, but also facilitate drilling and connection;

[0081] ③ Several locking end caps located at both ends of the inner slide rail 1 and the outer slide rail 2 cover the cut sections of the corresponding slide rails, which serve a decorative purpose while blocking the ball assembly 9 and preventing the inner slide rail 1 from disengaging from the outer slide rail 2 during the pulling process.

[0082] ④ The outer slide rail 2 is consistent with the front and rear stop bars, serving as both a slide rail and a drawer side, increasing usable space and making it more simple and aesthetically pleasing;

[0083] ⑤ The locking end cap corresponding to the inner slide rail 1 adopts a top ball design, which cooperates with the recessed structure of the locking end cap corresponding to the outer slide rail 2 to generate a locking force when the inner slide rail 1 and the outer slide rail 2 are closed, thus solving the problem that the inner slide rail 1 and the outer slide rail 2 are easy to slide out after they are closed.
