Description

Technical Field

[0001] Embodiments of the present invention relate to a joinery component configured to be interlocked via a mechanical locking device to form a joinery product / jointed woodwork / mortise and tenon joint / jointed woodwork. The joinery product can be, for example, furniture components such as bookshelves, cabinets, wardrobes, boxes, and drawers, and can be subsequently disassembled. Background Technology

[0002] Traditionally, furniture components such as drawers and cabinets are assembled using screws. However, in recent years, screwless assembly technology has been gradually developing in several directions.

[0003] Prior art, such as WO 2015 / 038059, discloses furniture products equipped with mechanical locking elements. These furniture products include a first panel and a second panel connected by a mechanical locking element, which includes a rod-shaped element, an insertion groove, a locking groove, and a locking element.

[0004] There is a need for a locking device for joinery products that has an optimized and improved locking effect. Summary of the Invention

[0005] The purpose of at least some embodiments of the present invention is to provide improvements over the above-described techniques and prior art.

[0006] Another object of at least some embodiments of the present invention is to provide a locking device that facilitates the production of joinery and the disassembly of joinery.

[0007] Previously, existing technology assembled joinery (such as furniture or furniture parts) using compressible locking elements and two or more tenons / pins. To ensure the stability of the joinery, the compressible locking elements prevent the assembled elements from moving relative to each other within a plane. The tenons are configured to prevent the assembled elements from moving in a direction perpendicular to said plane. Furthermore, by providing two spatially separated attachment points, the tenons also prevent the assembled elements from rotating relative to each other.

[0008] In some joinery products, space is limited for arranging compressible locking elements and at least two tenons. This is particularly true for joinery products such as shallow drawers, like various kitchen drawers. Drawers designed to hold, for example, cutlery are typically shallow so that users can easily see the items stored inside. It can be difficult to install a mechanical locking system in such shallow drawers while simultaneously achieving a stable joinery product that can withstand harsh environments (e.g., in a kitchen) and high-frequency use. Therefore, an improved joinery product is needed.

[0009] On one hand, a joinery is provided. The joinery includes a first joinery member having a first edge surface, a second edge surface, and a first joinery member surface. The second edge surface is adjacent to the first edge surface, and a first attachment surface is at least a portion of either the first edge surface or the second edge surface.

[0010] The joinery also includes a second joinery component having a second joinery component surface, a third joinery component surface, a third edge surface, and a fourth edge surface. The second attachment surface is at least a portion of the second joinery component surface, the third edge surface, or the fourth edge surface. The first attachment surface faces the second attachment surface and is configured to lock onto the second attachment surface.

[0011] The joinery also includes a third joinery component positioned in a joinery component groove, the joinery component groove being formed in a surface including a second attachment surface and an adjacent surface of the first joinery component.

[0012] The joinery also includes a mechanical locking device comprising a tenon protruding / extending from a first attachment surface at a tenon angle and an insertion groove extending into a second attachment surface. The insertion groove is configured to receive the tenon.

[0013] The mechanical locking device also includes a compressible locking element and a locking groove, the compressible locking element being partially positioned in a first woodworking groove on a first attachment surface, and the locking groove located in a second attachment surface being configured to receive the compressible locking element.

[0014] The locking surface of the locking groove is configured in the locking position to engage with a compressible locking element for locking the first joinery member relative to the second joinery member in one or more directions in the plane of the first attachment surface.

[0015] The inclination / slope of the tenon can suppress the displacement of the first joinery member relative to the second joinery member along the normal direction of the first attachment surface.

[0016] The mechanical locking device also includes a locking member disposed in a groove in the joinery member. The third joinery member is locked in the groove of the joinery member by the locking member to suppress rotational displacement of the first joinery member relative to the second joinery member in multiple directions in the plane of the first attachment surface.

[0017] The first, second, and third joinery components of this joinery are locked together by a mechanical locking device. The components of the mechanical locking device interact with each other, locking the joinery components in three dimensions.

[0018] Existing locking systems use two or more tenons to prevent two adjacent joinery components from rotating relative to each other. In shallow joinery, such as shallow drawers, there may not be enough space to accommodate at least two tenons. This disclosure uses a locking member to lock a third joinery component relative to the first and second joinery components. Therefore, rotation of the first and second joinery components is prevented due to the mutual locking with the third joinery component. This solution eliminates the need for one or more tenons, replacing them with a locking mechanism that locks the third joinery component.

[0019] This makes it possible to produce stable, durable light-finish woodwork. This is particularly advantageous for items such as kitchen drawers that are subject to high wear and tear and may be exposed to harsh environments.

[0020] In one embodiment, the locking device includes two locking components.

[0021] In one embodiment, the locking device includes more than two locking members.

[0022] In one embodiment, the third joinery member interacts with the inner surface of the joinery member groove to suppress rotational displacement of the first joinery member relative to the second joinery member in a direction within the plane of the first attachment surface. In this embodiment, a locking mechanism may not be necessary. Instead, the third joinery member can be locked in the joinery member groove by friction or by the complementary shape of the groove relative to the third joinery member.

[0023] In one embodiment, the joinery groove includes a locking member groove configured to receive a locking member. This provides reliable positioning of the locking member. The locking member groove may have the same longitudinal extension as the joinery groove. This allows for longitudinal adjustability of the locking member within the locking member groove.

[0024] In one embodiment, the locking member groove may be provided along a portion of the extension of the joinery member groove.

[0025] In one embodiment, the length of the locking member groove can approximately correspond to the length of the locking member. This facilitates the placement of the locking member.

[0026] In one embodiment, the locking member is an elongated / long flexible tenon. The elongated shape of the flexible tenon means that it requires less installation space compared to other types of locking members, such as circular or semi-circular locking members, or locking members that include a cam-shaped surface.

[0027] In one embodiment, the locking member is arranged in a locking member groove provided in a joinery member groove.

[0028] The flexible tenon is configured to apply pressure to the third joinery by abutting against the joinery groove. The flexible tenon can be configured to bend / bend / flex into the locking member groove when the third joinery is inserted into the joinery groove. Once the third joinery is positioned in the joinery groove, the flexible tenon can be configured to bend backward, partially disengaging from the locking member groove, and pressing against the third joinery, thus allowing the third joinery to press against the side surface of the joinery groove. The advantage of an elongated flexible tenon is that it can apply pressure distributed over a larger surface area or a larger longitudinal extension of the third joinery. Therefore, it provides an optimized and improved locking effect compared to single-point locking methods or locking methods without a large longitudinal extension.

[0029] The advantage of a slender locking tongue is that its design can provide a constant locking force over time.

[0030] In one embodiment, the flexible tenon can be glued to the locking member groove. In another embodiment, the flexible tenon can be fixed to the locking member groove via a friction connection. In one embodiment, the friction connection may include protrusions disposed on the upper and / or lower surfaces of the tenon.

[0031] In one embodiment, the mechanical locking device may include only one tenon at the first attachment surface. This is particularly advantageous for shallow joinery, where there may not be enough space to accommodate several tenons to secure adjacent joinery components relative to each other.

[0032] In one embodiment, the compressible locking element may be positioned closer to the third joinery component than the tenon.

[0033] In one embodiment, the tenon can be positioned further away from the third joinery component than the compressible locking element.

[0034] In joinery comprising only one tenon, it is advantageous to position the compressible locking element closest to the third joinery member, thus keeping the tenon away from the third joinery member. Since the tenon prevents the first joinery member from shifting relative to the second joinery member along the normal direction of the first attachment surface, this placement of the tenon can suppress or prevent the formation of a gap between the first and second joinery members at an attachment point away from the third joinery member.

[0035] In one embodiment, the compressible locking element in its uncompressed state protrudes partially from the first attachment surface. The protruding portion of the compressible locking element may be configured to be received by a locking groove to lock the first and second joinery members together.

[0036] In one embodiment, the compressible locking element in a compressed state is configured to be substantially received within a groove in the first joinery member.

[0037] In one embodiment, in the locked position, the compressible locking element is configured to partially shift into the locking recess.

[0038] The compressible locking element can be configured to be compressed into a groove in the first joinery during the assembly of the first and second joinery components. When the first and second joinery components are correctly positioned relative to each other, the compressible locking element can be configured to partially release from the groove in the first joinery component and partially enter the locking groove.

[0039] In one embodiment, the compressible locking element and the tenon are positioned on a straight line extending within the longitudinal extension range of the first attachment surface.

[0040] In one embodiment, the compressible locking element and the tenon are arranged at a different perpendicular distance from a straight line extending within the longitudinal extension range of the first attachment surface. The corresponding distance from this straight line can be less than 30 mm, for example less than 20 mm, for example less than 10 mm, for example less than 5 mm. The placement of the tenon and the compressible locking element can improve the interlocking between the first and second joinery components, which can improve the stability of the joinery.

[0041] In one embodiment, the tenon angle relative to the first attachment surface is in the range of 20°-75°, for example, in the range of 35°-55°, for example, in the range of 40°-50°, for example, approximately 45°. The tenon angle can improve the interlocking between the first and second joinery components, which can improve the stability of the joinery.

[0042] In one embodiment, the insertion groove extends into the second attachment surface at a groove angle relative to the second attachment surface, and the difference between the tenon angle and the groove angle is in the range of 0°-6°, for example, in the range of 1°-5°, for example, in the range of 2°-4°, for example, about 3°. A smaller difference between the tenon angle and the groove angle can facilitate the assembly of the first and second joinery components.

[0043] In one embodiment, one side of the joinery recess (which is adjacent to the first attachment surface) extends relative to the first attachment surface at the joinery recess angle.

[0044] In one embodiment, the groove angle of the joinery component is in the range of 70°-110°, for example, in the range of 80°-100°, for example, in the range of 85°-95°, for example, approximately 90°. When the groove angle of the joinery component is close to 90°, it facilitates the assembly of the first joinery component and the second joinery component.

[0045] In one embodiment, the difference between the tenon angle and the joinery recess angle is 10°-100°, for example 20°-70°, for example 30°-60°, for example 40°-50°, for example approximately 45° or approximately 42°.

[0046] In one embodiment, the locking member has a longitudinal shape, the length of which is parallel to the length direction of the groove in the joinery member. The longitudinal shape of the locking member allows for a more uniform distribution of pressure applied to the third joinery member.

[0047] In one embodiment, the locking member is configured to be compressed toward the bottom surface of the locking member groove. When the locking member is compressed into the locking member groove, a third joinery member may be allowed into the joinery groove. When the third joinery member is received in the joinery groove, the locking member may be configured to release the compression and pressure may be applied to the third joinery member, pressing it against the side surface of the joinery groove.

[0048] In one embodiment, the flexible tenon is made of a polymer material.

[0049] In one embodiment, the joinery is either a cabinet or a drawer, optionally a kitchen drawer. The joinery may include two first joinery members and two second joinery members. The joinery may include a locking device disposed at each intersection between the first and second joinery members. The joinery may include a total of four locking devices.

[0050] In one embodiment, the height of the joinery, corresponding to the length of the long side of the third edge surface, is 30-120 mm, for example 50-100 mm, such as approximately 90 mm. The height of the joinery may complicate or prevent the accommodation of more than one tenon. Joinery with the aforementioned height can be stabilized by a locking device as described above.

[0051] In one embodiment, the core material of one or more of the first, second, and third joinery components includes wood fiberboard (optionally one of HDF, MDF, plywood, solid wood, or particleboard), reinforced plastic board, and wood fiber composite board.

[0052] In one embodiment, the core material is provided with a decorative layer.

[0053] The stability of joinery is achieved through the engagement of each of the compressible locking elements, tenons, and elongated locking members with the first, second, and third joinery members that will lock together. Each compressible locking element, tenon, and elongated locking member ensures stability between the joinery members to be locked in one or more dimensions. This ultimately results in a stable connection between the joinery members, producing a stable joinery product.

[0054] The joinery may include two first elongated joinery members and two second elongated joinery members, as well as a third joinery member. The first and second joinery members may be arranged in a frame-like manner, with the first joinery members facing each other and the second joinery members facing each other. The joinery may also include a locking device, which may include a tenon, a compressible locking element, a tenon locking groove for receiving the tenon in the locked state of the joinery, and a locking groove for the compressible locking element for receiving the compressible locking element in the locked state of the joinery. The tenon and the compressible locking element may be arranged in one of the first joinery members or in one of the second joinery members. The tenon locking groove and the locking groove for the compressible locking element may be arranged in another first joinery member or another second joinery member.

[0055] The locking device may also include joinery grooves. Joinery grooves may be provided in each first joinery and each second joinery. The joinery grooves may be configured to receive a third joinery. The joinery grooves may be configured to receive the circumferential edge portion of the third joinery. The ends of the first joinery can be attached to the corresponding ends of the second joinery by means of the locking device. Attached Figure Description

[0071] Specific embodiments of the invention will now be described with reference to the accompanying drawings. However, this disclosure may be implemented in many different forms and should not be construed as limiting it to the embodiments of joinery presented herein; rather, these embodiments are provided to make the disclosure exhaustive and to fully convey the scope of the disclosure to those skilled in the art. The terminology used in the detailed description of the embodiments shown in the drawings is not intended to limit the disclosure. In the drawings and description, the same numerals denote the same elements.

[0072] Figures 1A-1D Different views of a joinery product according to one embodiment are shown. The joinery product may be part of furniture or furniture components, such as bookshelves, cabinets, wardrobes, chests, drawers, or furniture parts.

[0073] Because joinery has a relatively small height H, there may not be enough space to accommodate a traditional locking system that includes two tenons. There may not be enough space to accommodate two tenons, or the two tenons may be too close together, thus reducing the stability and / or strength of the joinery. Therefore, an improved locking system suitable for shallow joinery is needed.

[0074] The surface described herein extends in two directions, which can be referred to as a first extension range and a second extension range perpendicular to the first range (or a first extension direction and a second extension direction). Both can also be referred to as a longitudinal extension range and an extension range perpendicular to it, the longitudinal extension range being along the main extension direction of the surface.

[0075] The joinery includes a first joinery component 10, a second joinery component 20, and a third joinery component 30. The first joinery component 10 may have a first principal plane, the second joinery component 20 may have a second principal plane, and the third joinery component 30 may have a third principal plane. When the first joinery component 10, the second joinery component 20, and the third joinery component 30 are assembled onto the joinery, the first principal plane, the second principal plane, and the third principal plane are substantially perpendicular to each other.

[0076] The joinery is provided with a mechanical locking system configured to lock the first joinery component 10, the second joinery component 20, and the third joinery component 30 together. This mechanical locking device will be described further below.

[0077] The first joinery member 10 has a first edge surface 11, a second edge surface 12, and a first joinery member surface 13. The second edge surface 12 is disposed adjacent to the first edge surface 11. The first joinery member 10 also includes a first attachment surface 15. The first attachment surface 15 is at least a portion of the first edge surface 11 or the second edge surface 12.

[0078] The second joinery component 20 has a second joinery component surface 22, a third joinery component surface 23, a third edge surface 21, and a fourth edge surface 24. The second joinery component 20 also includes a second attachment surface 25. The second attachment surface 25 is at least a portion of either the second joinery component surface 22 or the third edge surface 21. In the installed state of the joinery, the first attachment surface 15 faces the second attachment surface 25 and is configured to lock with the second attachment surface 25.

[0079] Including one of the second joinery surface 22 or the third edge surface 21 of the second attachment surface 25 (in Figures 1A-1D The surface 22 of the joinery component is provided with joinery component grooves 29, for example... Figures 2A-2D As shown.

[0080] Any surface (e.g., any flat surface) of each joinery component 10, 20 may constitute an attachment surface 15, 25, although for transport purposes (e.g., to achieve flat packaging), the first attachment surface 15 may be an edge surface (or may be part of an edge surface).

[0081] The joinery includes two first joinery members 10 and two second joinery members 20. The first joinery members 10 are arranged opposite each other, and the two second joinery members 20 are arranged opposite each other. Thus, one first joinery member 10 is arranged adjacent to two second joinery members 20, and one second joinery member 20 is arranged adjacent to two first joinery members 10. When attached to each other to form the joinery, the two first joinery members 10 and the two second joinery members 20 are arranged in a frame-like manner.

[0082] The second edge surface 12 of each first joinery component 10 is also provided with joinery component grooves 29, for example, Figure 2A-2D As shown.

[0083] When installed in a frame-like manner, the second edge surfaces 12 of the corresponding first joinery members 10 face each other.

[0084] The joinery groove 29 is provided in surfaces 22, 21, and 24. Surfaces 22, 21, and 24 include a second attachment surface 25 and a surface of the first joinery 10. In the assembled state of the first joinery 10 and the second joinery 20, the surface is adjacent to surfaces 22, 21, and 24 in the second joinery 20.

[0085] When the first joinery component 10 and the second joinery component 20 are attached to each other in a frame-like manner, the joinery component grooves 29 of the first joinery component 10 and the second joinery component 20 form continuous / connected grooves along the inner periphery of the joinery.

[0086] The height H of the joinery corresponding to the long side length of the third edge surface 21 is preferably 30-120 mm, for example 50-100 mm, for example about 90 mm.

[0087] Refer to Figure 2- Figure 4 The joinery also includes a mechanical locking device 60. In Figures 2-3, joinery components 10 and 20 and the mechanical locking device 60 are shown in an assembled state of the joinery. Figure 4 In the image, joinery components 10 and 20 and mechanical locking device 60 are shown in an unassembled state of the joinery.

[0088] The mechanical locking device 60 includes a tenon 31 projecting from the first attachment surface 15 of the first joinery member 10 at a tenon angle a1. The mechanical locking device 60 also includes a compressible locking element 40, which is partially positioned in a first joinery member recess 41 on the first attachment surface 15. The compressible locking element 40 protrudes partially from the first attachment surface 15 in its uncompressed state. The uncompressed state can be, for example, the locked state.

[0089] The mechanical locking device 60 also includes an insertion groove 32 disposed in the second attachment surface 25. The insertion groove 32 extends into the second joinery member 20. The insertion groove 32 extends into the second attachment surface 25 of the second joinery member 20 at an angle approximately corresponding to the tenon angle α1. When the first joinery member 10 and the second joinery member 20 are attached to each other, the insertion groove 32 is configured to receive a tenon 31. When the tenon 31 extends into the insertion groove 32, it interacts with the inner peripheral surface of the insertion groove 32. The engagement between the tenon 31 and the insertion groove 32 inhibits displacement of the first joinery member 10 relative to the second joinery member 20 along the normal direction N1 of the first attachment surface 15.

[0090] The mechanical locking device 60 also includes a locking groove 50 disposed in the second attachment surface 25. The locking groove 50 extends into the second joinery member 20. The locking groove 50 extends into the second joinery member 20 in the normal direction N2 of the second attachment surface 25. The locking groove 50 is configured to receive a compressible locking element 40 when the first joinery member 10 and the second joinery member 20 are attached to each other.

[0091] The locking recess 50 includes a locking surface 51. The locking surface 51 is the peripheral surface of the locking recess 50. The locking surface 51 is configured to interact with the compressible locking element 40 when the compressible locking element 40 extends into the locking recess, such that the first joinery member 10 is locked relative to the second joinery member 20 in a direction in the plane of the first attachment surface 15.

[0092] The third joinery component 30 is arranged in the joinery groove 29 of the corresponding joinery components 10 and 20. The circumferential edge portion of the third joinery component 30 is configured to be received by the joinery groove 29.

[0093] like Figure 5 As shown, each joinery groove 29 includes a bottom surface 44, an upper surface, and a lower surface 45.

[0094] In one embodiment, the joinery groove 29 is configured to receive a locking member 33 (e.g., a rod or tenon) configured to lock a third joinery member 30 against the side surface 45 and bottom surface 44 of the joinery groove 29. Preferably, the locking member 33 is received in a locking member groove 28 disposed in the joinery groove 29. The locking member 33 (e.g., a rod or tenon) may have a longitudinal shape. The longitudinal length of the locking member may be parallel to or substantially parallel to the longitudinal length of the locking member groove 28. Other embodiments of the locking member 33 will be further explained below.

[0095] In one embodiment, the locking member includes a flexible tongue 33 disposed in a locking member groove 28. The locking member groove 28 is preferably disposed in the side surface 45 of the joinery member groove 29, for example... Figure 3A , Figure 3B and Figure 5 As shown. The flexible tenon 33 can mate with the tenon groove 27 in the third joinery, for example as shown in Figures 10A-10F, to lock the first joinery 10 and / or the second joinery 20 onto the third joinery 30.

[0096] One or more of the tenon groove 27, locking member groove 28 and joinery member groove 29 may be formed by mechanical cutting (e.g., milling).

[0097] In one embodiment, the third joinery member 30 is locked against the side surface 45 and bottom surface 44 of the joinery member groove 29 by means of complementary shapes or by friction.

[0098] When the third joinery member 30 is locked in the joinery member groove 29, it is configured to interact with the surfaces 44, 45 of the joinery member groove 29 to suppress rotational displacement of the first joinery member 10 relative to the second joinery member 20 in a direction in the plane of the first attachment surface 15.

[0099] The fit between the tenon 31 and the insertion groove 32, the locking surface 51 and the compressible locking element 40, and the surfaces 44, 45 of the third joinery member 30 and the joinery member groove 29 results in the joinery requiring only one tenon 31 at each joint between the two joinery members. For example, the mechanical locking device 60 includes only one tenon 31 at the first attachment surface 15.

[0100] Figures 6A-6D A locking member 33 in the form of a flexible tenon is shown according to one embodiment. The flexible tenon 33 has a longitudinal or elongated shape.

[0101] The flexible tenon 33 is configured to be movably arranged in the joinery groove 29, preferably in the locking element groove 28 within the joinery groove 29. The length direction of the flexible tenon 33 is configured such that when the flexible tenon 33 is arranged in the locking element groove 28, it is parallel to the length direction of the joinery groove 29 and the locking element groove 28.

[0102] Figures 6A-6B The flexible tenon 33 is shown in the locked position. Figures 6C-6D The flexible tenon 33 is shown in the assembly process of joinery products. Figure 6B It shows Figure 6A Cross-sectional view of the flexible tenon 33. Figure 6D It shows Figure 6C A cross-sectional view of the flexible tenon 33 is shown. The flexible tenon 33 includes a bendable protrusion 34. A groove 36 is preferably arranged at each bendable protrusion 34 of the flexible tenon 33. A space 35 is provided between the flexible tenon 33 and the bottom surface of the locking member groove 28.

[0103] Figure 6C The diagram illustrates the pushing of a flexible tenon 33 into a locking member groove 28 during the assembly of a joinery. The flexible tenon 33 is configured to be pressed against the bottom surface of the locking member groove 28 during the assembly of the joinery. The flexible tenon 33 is configured to spring back toward its initial position when the component to be connected has reached the locking position.

[0104] The flexible tenon 33 may have a first displacement surface 37 and an opposing second displacement surface 38 configured to shift along the respective side surface 45 of the locking member groove 28.

[0105] Figures 7A-7E and Figure 8 An embodiment is shown that is configured to insert a flexible tenon 33 into a locking member groove 28.

[0106] Figures 7A-7E Different views of an embodiment of the flexible tenon are shown. Figures 8-9B It shows Figures 7A-7E An enlarged view of the cross-section AA of the embodiment shown.
