Description

Technical Field

[0001] This disclosure relates to a joinery device including joinery components configured to lock into each other. The joinery device may be included in a joinery assembly such as a furniture assembly. This disclosure also relates to a joinery assembly including the joinery device and additional joinery components. Background Technology

[0002] WO 2023 / 191694 A1 discloses a locking device comprising a spring and a locking element, such as a locking pin or locking disc, for locking two elements, such as first and second panels, to each other. The first and / or second panel may be furniture components, which may be part of a furniture product. The locking pin may include a truncated conical end portion, which facilitates locking the two panels to each other.

[0003] Despite the advantages of the aforementioned technologies, some products, such as those including furniture components, may require better locking performance. Summary of the Invention

[0004] Therefore, at least the purpose of the embodiments of this disclosure is to provide a joinery device whose locking configuration is more resistant to high loads, especially high impact forces.

[0005] At least one other object of the embodiments of this disclosure is to provide a joinery device that maintains the possibility of disassembling the joinery device without damaging the joinery components.

[0006] Another object of at least the embodiments of this disclosure is to provide a corresponding joinery assembly including such joinery device.

[0007] These and other objects and advantages, which will become apparent from the description, have been achieved through the various aspects, embodiments, and examples described below.

[0008] According to a first aspect of this disclosure, a joinery device is provided, comprising a first joinery component and a second joinery component, the first joinery component and the second joinery component being configured to lock together to obtain a locked state. The first joinery component includes: at least one cavity disposed in a mounting side of the first joinery component and extending along a cavity direction at a cavity angle relative to a first plane extending along the mounting side of the first joinery component; and a recess disposed in the mounting side of the first joinery component. The second joinery component includes: at least one protrusion disposed in a mounting region of the second joinery component and extending along a protrusion direction at a protrusion angle relative to a second plane extending along the mounting region of the second joinery component; and an insert disposed in the mounting region of the second joinery component, wherein the insert is displaceable and / or compressible along its primary direction. The at least one cavity and the at least one protrusion are configured to engage with each other for locking the first and second joinery components together in a first direction perpendicular to the first plane. The recess and the insert are configured to engage with each other for locking the first and second joinery components together in a second direction along the first plane. The insert includes a retaining member comprising at least one protrusion, such as multiple protrusions. The retaining member is configured to engage with the recess wall of the recess in a locked state. Alternatively or additionally, the insert is disposed in an insertion groove of a second joinery, and the retaining member is configured to engage with the groove wall of the insertion groove in a locked state.

[0009] By means of the retaining member according to this disclosure, higher friction can be provided between the insert and the recess and / or the insertion groove, thereby better securing the position of the insert in the recess and / or the insertion groove. For example, the insert can be prevented from slipping out of the recess and / or the insertion groove to a greater extent. Therefore, higher locking strength can be obtained, and when the first joinery component is subjected to high loads, especially high impact forces, along the first direction, unlocking of the joinery can be hindered or even prevented.

[0010] Joinery can be included in joinery components such as furniture components. For example, a furniture component can be a cabinet component or a shelf component. It should be emphasized that the embodiments of the first and second aspects described herein are particularly applicable to wall-mounted cabinet components, especially those including a first joinery component forming the bottom, such as the bottommost joinery component of the wall-mounted cabinet component.

[0011] The joinery components mentioned in this article can be furniture components, such as cabinet components or shelf components. For example, joinery components can be paneling.

[0012] The joinery components described herein can be wood-based joinery components, preferably including a core and optionally including decorative structures, such as decorative layers attached (e.g., adhered) to the core. For example, the core can be high-density fiberboard (HDF), medium-density fiberboard (MDF), particleboard, or plywood. Furthermore, the decorative structure can be or may include decorative layers, such as foil, paper, polymer base layer, laminate, or wood veneer. Alternatively or additionally, the decorative structure may include a painted surface layer. Cavities, recesses, and insertion grooves (defined below) may be arranged in the core.

[0013] The engagement between the cavity and the protrusion, and between the recess and the insert, defines the locked state of the first and second joinery components. Furthermore, an unlocked state of the joinery components can be obtained when there is no engagement between the cavity and the protrusion and / or the recess and the insert.

[0014] The lateral direction of the insert can be perpendicular to the main direction.

[0015] To simplify the description here, we will usually refer to “protrusion” (or “cavity” or “projection”) rather than “at least one protrusion (or cavity or projection)”, but it is important to emphasize that “at least one protrusion (or cavity or projection)”, “at least two protrusions (or cavities or projections)” and “multiple protrusions (or cavities or projections)” are all included in the concept of “protrusion” (or “cavity” or “projection”).

[0016] Generally, in this document, mating objects such as surfaces, portions, components, or elements can be mated by direct or indirect engagement. Examples of mating objects include cavities and protrusions, as well as recesses and inserts. In any of the embodiments described herein, a sealant, such as wax or adhesive, may be present between the mating objects, thereby providing an example of indirect engagement.

[0017] The retaining member can be a friction element used to increase friction between the insert and the recess.

[0018] The protrusions may be spaced apart from each other by a distance along the main direction of the insert. For example, the protrusions may form corrugations on the insert. Thus, localized pressure can be provided from the abutment recess of the retaining member.

[0019] In some embodiments, the protrusions may be evenly spaced. This may be advantageous when the first joinery component comprises high-density fiberboard such as high-density laminate (HPL) and / or substantially homogeneous boards.

[0020] The level of friction can be further fine-tuned by adjusting the spacing between the protrusions to suit the material composition of the joinery component, such as its density distribution. Typically, the spacing between different pairs of adjacent protrusions can vary.

[0021] In some embodiments, the spacing between a first pair of adjacent protrusions may be smaller than the spacing between a second pair of adjacent protrusions, wherein the first pair is arranged closer to the end section of the insert compared to the second pair. Smaller and larger spacing between the protrusions can provide lower and higher pressure (and / or force) and friction, respectively, on the core of the joinery. Therefore, higher friction and higher pressure (and / or force) can be provided between the insert and the recess in the outer region of the joinery compared to the inner region located inside the outer region of the joinery along its thickness direction. For example, a wood-based first joinery (preferably comprising a core in the form of HDF board, MDF board, particleboard, or plywood, and a wood-based first joinery with a decorative structure such as a decorative layer comprising a polymer base layer, laminate, or wood veneer) may have a higher density in the outer region than in the inner region. Therefore, varying spacing can be particularly suitable for use with such a wood-based first joinery, as higher friction can be provided in the high-density region.

[0022] Another effect of the smaller spacing between adjacent protrusions is that an adjustable pressure distribution (and / or force distribution) can be achieved, thus providing sufficient locking strength while maintaining the possibility of disassembling the joinery components without damaging them. This may be particularly important for wood-based first joinery components that include the varying density distributions described above (e.g., cores in the form of HDF, MDF, particleboard, or plywood, and wood-based first joinery components with decorative structures as described above).

[0023] In some embodiments, the protrusions may be spaced apart from each other by a distance along the circumferential direction of the insert.

[0024] The protrusion can extend around the entire circumference of the retaining member. Therefore, the insert can be positioned more easily into the insertion groove. Furthermore, at least in some applications, the manufacture of the insert, for example, by injection molding, can be simplified.

[0025] The retaining member may generally / approximately taper towards the end section of the insert in the longitudinal direction. For example, the lateral extension range / length of the protrusion may decrease towards the end section. Alternatively or additionally, the recess wall may taper in the depth direction of the recess. For example, the end portion of the insert and / or the recess wall may have a truncated conical shape. Therefore, a larger contact area can be provided between the insert including the protrusion and the recess, particularly for low-density core materials such as particleboard, thereby achieving higher locking strength along the first direction. Furthermore, wear on the recess can be reduced during disassembly of the joinery.

[0026] The corresponding protrusions in the protrusions may extend from the base surface of the retaining member at different heights.

[0027] At least some of the protrusions may extend from the base surface of the retaining member to a virtual truncated conical surface that forms a non-zero angle with respect to the base surface.

[0028] The lateral extension of the protrusion can decrease along the main direction of the insert toward the end section of the insert.

[0029] In the locked state, the locking portion of the insert, such as the locking portion of the retaining member, can engage with the locking surface of the recess, and optionally, a clearance may exist between the head surface of the head portion of the insert and the recess wall arranged opposite to / opposite to the engaging recess wall of the recess.

[0030] The mounting side of the first joinery component may be located in the first surface of the first joinery component. The mounting area may be located in the first side edge of the second joinery component.

[0031] During the locking process, the insert can be configured to be compressed, thus presenting a compressed state, and subsequently, the insert can be at least partially extended towards an extended state for locking the second joinery to the first joinery. For example, the insert can be locked by pre-stretching against a recess.

[0032] The second joinery component can be configured to lock onto the first joinery component by relatively displacing the second joinery component relative to the first joinery component in a locking direction that extends substantially parallel to at least one of the cavity direction and the protrusion direction.

[0033] The insert can be formed separately from the second joinery component. For example, an insert including a retaining member and / or a main body and a serpentine element (as defined below) can be formed by injection molding.

[0034] The insert can be arranged in the insertion groove of the second joinery component.

[0035] The insert and / or the insertion groove therein may extend substantially along the normal direction of the second plane. Therefore, the insertion groove can be formed more easily, for example, by drilling.

[0036] The retaining member may include an external retaining member and / or an internal retaining member. The external (or internal) retaining member may be configured to engage with a recess (or insertion groove) in a locked state. It should be emphasized that, in some embodiments, the retaining member may consist only of an internal retaining member.

[0037] The at least one protrusion may be disposed in the body portion of the insert, wherein the body portion is configured to engage with the groove wall of the insertion groove in the locked state. Therefore, higher locking strength can be provided, and unlocking of the joinery can be further impeded or even prevented when the first joinery component is subjected to high loads, particularly high impact forces, along the first direction. Furthermore, the insert is better secured in the insertion groove during the high load.

[0038] The insert may include a spring, such as a static load spring.

[0039] The insert may include multiple connected serpentine elements. The serpentine elements may be flexible and may enable compressibility of the insert along a primary direction (e.g., the axial direction).

[0040] In the unlocked state of the first and second joinery components, the protrusion angle can be smaller than the cavity angle. Therefore, the first and second joinery components can be locked together by pre-tensioning. In the unlocked state, the protrusion angle can differ from the cavity angle by 0.5° to 6°, for example, 2° to 4°. For example, as described above, the protrusion angle can be smaller than the cavity angle.

[0041] Generally, in this document, the cavity angle and / or the protrusion angle can be acute angles, for example, acute angles relative to the first and / or second planes. In a non-limiting example, the cavity angle can be in the range of 20° to 75°, for example, in the range of 30° to 60°, such as about 45°, and / or the protrusion angle can be in the range of 20° to 75°, for example, in the range of 30° to 60°, such as about 42°.

[0042] Generally, in this paper, the protrusion angle and cavity angle can be measured by a CT scanner in both the unlocked and locked states.

[0043] The opposing walls of each cavity may be substantially parallel. The cross-section of the cavity and / or recess may be circular.

[0044] According to a second aspect of this disclosure, a joinery assembly is provided, comprising a joinery device according to any embodiment of the first aspect, and further comprising at least one additional joinery component, such as a plurality of additional joinery components. Embodiments of the second aspect are substantially similar to embodiments of the first aspect, and particularly embodiments of the joinery device, which are thus referenced.

[0045] Joinery components can be furniture components, such as cabinet components or shelf components.

[0046] Generally, unless otherwise expressly defined, all terms used herein, such as those used in the claims, will be interpreted according to their ordinary meaning in the art. Unless otherwise expressly stated, all references to “a / an / the / described [element, device, component, mechanism, step, etc.]” ​​shall be publicly interpreted as referring to at least one instance of said element, device, component, mechanism, step, etc. References to one or more “at least one element”, etc., may be simply referred to as “element”.

[0067] Next, we will refer to, for example Figures 1a-1c Various embodiments of the joinery device 10 and the corresponding joinery components 20 are described in 2a-2d, 3a-3b, 4a-4f, 5a-5f, 6a-6f, 7a-7h, 8a-8j, 9a-9b and 10a-10c.

[0068] This disclosure relates to a joinery device 10 comprising a first joinery component 1 and a second joinery component 2. Joinery components 1 and 2 may be furniture components, such as cabinet components or shelf components. For example, joinery components may be paneling, such as furniture paneling.

[0069] The first (or second) joinery component 1 (or 2) may include a first surface 1b (or 2b) and a second surface 1c (or 2c) opposite to the first surface 1b (or 2b).

[0070] The first joinery component 1 and / or the second joinery component 2 may be wood-based joinery components, preferably comprising a core 18, and optionally including a decorative structure 19 such as a decorative layer attached to the core 18. For example, the core 18 may be HDF board, MDF board, particleboard, HPL board, or plywood. Furthermore, the decorative layer may be or may include foil, paper, a polymer base layer, a laminate, or wood veneer. For example, the polymer base layer may include thermosetting resins such as melamine-formaldehyde resin, or thermoplastic polymers such as polyvinyl chloride (PVC). Alternatively or additionally, the decorative structure 19 may include a painted surface layer.

[0071] The first joinery component 1 includes at least one cavity 3, such as a plurality of cavities 3, and a recess 4. The cavity 3 is arranged in the mounting side 1a of the first joinery component 1 and at a cavity angle preferably acute relative to a first plane M1 extending along the mounting side 1a. Extending along the cavity direction P1. The mounting side 1a can be disposed in the first surface 1b. The recess 4 is arranged in the mounting side 1a. Cavity angle. It can be in the range of 20° to 75°, for example, in the range of 30° to 60°, for example, about 45°.

[0072] The second joinery component 2 includes at least one protrusion 5, or a plurality of protrusions 5, and an insert 6. The protrusions 5 are arranged in the mounting area 2a of the second joinery component 2 and are positioned at a protrusion angle, preferably an acute angle, relative to a second plane M2 extending along the mounting area 2a. Extending along the protrusion direction P2. The mounting area 2a can be located within the first side edge 2d. Protrusion angle. It can be in the range of 20° to 75°, for example, in the range of 30° to 60°, for example, about 42°.

[0073] Each protrusion 5 can be axially rigid. Therefore, the protrusion is substantially incompressible along its axial direction. Each protrusion 5 can be a rod-shaped element, such as a cylindrical element. The protrusion 5 is preferably disposed in the hole 5c by press fitting and / or adhesive. The hole 5c can be formed by drilling and can be tilted corresponding to the angle of the protrusion. The angle. Along the protrusion direction P2, the cross-section of each protrusion 5 is preferably circular. Preferably, the protrusions 5 are formed separately from the second joinery component 2. For example, they can be plugs or tenons, preferably polymer-based tenons or wooden tenons.

[0074] The insert 6 is disposed in the mounting area 2a, and preferably in the insertion groove 9 of the second joinery 2. The insert 6 can be displaced and / or compressed along its principal direction A, for example by spring loading. The principal direction A can be the axial direction of the insert.

[0075] The length K of the protrusion 5 is preferably a maximum length and / or the depth L of the cavity 3 can be 20-60 mm, for example 30-40 mm. The widths W1 and W3 of the cavity 3 and / or the protrusion 5 are preferably a maximum width of 5-10 mm, preferably about 8 mm. The widths W4 and W5 of the insert 6 and / or the insertion groove 9 are preferably a maximum width of 5-12 mm, for example 5-10 mm or 8-12 mm. Similarly, the width W2 of the recess 4 is preferably a maximum width of 5-12 mm, for example 7-11 mm or 8-12 mm.

[0076] Cavity 3 and protrusion 5 are configured to engage with each other, for example, to lock the first joinery component 1 and the second joinery component 2 together in a first direction D1 perpendicular to the first plane M1. Each protrusion 5 can be received in a corresponding cavity 3 for engagement between them. Furthermore, recess 4 and insert 6 are configured to engage with each other, for example, to lock the first joinery component 1 and the second joinery component 2 together in a second direction D2 along the first plane M1. Thus, a locked state of the first joinery component 1 and the second joinery component 2 in the first direction D1 and the second direction D2 can be obtained, see, for example... Figure 2b ,3a -3b, 6a-6c, 6f, 7b, 7e, 7h, 8c, 8f-8g, 8j, and 9b. Preferably, the first direction D1 and the second direction D2 are perpendicular to each other. Obviously, the cavity 3 and the protrusion 5 can also optionally help to lock the second joinery 2 to the first joinery 1 in the second direction D2. In addition, the cavity 3 and the protrusion 5 and / or the recess 4 and the insert 6 can help to lock the second joinery 2 to the first joinery 1 in a third direction D3, which is perpendicular to the first direction D1 and the second direction D2. The cavity 3 and the protrusion 5, as well as the recess 4 and the insert 6, can provide a locking device for the joinery.

[0077] A third plane M3 extending along surfaces 2b and / or 2c can be configured to be arranged perpendicular to the first plane M1 in the locked state.

[0078] The protrusion 5 may mate with the corresponding cavity 3 at the connecting surfaces 3b and 5b, which may be arranged in the wall 3a of the cavity 3 and the wall 5a of the protrusion. The connecting surfaces 3b and 5b may extend around a portion of the circumference of the protrusion and the cavity, for example, around their entire circumference.

[0079] The insert 6 may include a head portion 6g, which is preferably generally tapered. The insert 6 may include a locking portion 6h configured to engage with a locking surface 4c of the recess 4 for locking the joinery parts 1 and 2 in the second direction D2. The locking surface 4c is preferably disposed in the recess wall 4a, see, for example... Figure 3b , 6a 6c and 10a. Preferably, the transversely positioned inner head portion 6j (or outer head portion 6i) facing the opposite recessed wall 4b and opposite / opposite to the locking portion 6h is spaced apart from the opposite recessed wall 4b by a clearance 15. The locking portion 6h and the inner head portion 6j (or outer head portion 6i) may be disposed within the head portion 6g. For example, in the locked state, the inner head portion 6j (or outer head portion 6i) may be closer to the cavity 3 and / or the protrusion 5 along the D2 direction than the locking portion 6h. For example, the head length HL of the head portion 6g may be 3-7 mm, for example 4-6 mm.

[0080] In the locked state, the insert 6, for example, the topmost portion 6k along the main direction A, can be spaced apart from the bottom wall 4d of the recess 4.

[0081] Preferably, the cavity 3 and / or recess 4 are blind holes. Alternatively, the cavity 3 and / or recess 4 can be externally cut holes, such that they have extension lengths H1, H2, H1', ​​H2' in the mounting region 2a along a pair of non-parallel (e.g., perpendicular) horizontal directions, and these extension lengths are substantially the same. For example, they can be substantially circular or elliptical holes, preferably formed by drilling. Along the cavity direction P1, the cross-section of each cavity 3 is preferably circular, preferably such that the cavity inlet into the mounting side 1a is elliptical. Alternatively or additionally, for example along the first direction D1, the cross-section of the recess 4 is preferably circular. Optionally, the cavity inlet 3c is wider than the cavity interior portion 3d, for example, formed by a countersunk drill bit.

[0082] As in Figure 1b-1c As most clearly shown in 2a-2c, 3a, 6c, and 9a, the recess 4 may be arranged in the edge portion 11a of the joinery 1, and / or the insert 6 may be arranged in the edge portion 11b of the second joinery 2. For example, along the second direction D2, the recess 4 may be arranged outside each cavity 3, and along the second direction D2, the insert 6 may be arranged outside each protrusion 5. Thus, as Figure 3b As shown, the unlocking hole 22 in the first joinery component 1, which communicates with the recess 4 and is configured to provide access to the insert 6 (e.g., the unlocking hole shown and discussed in WO 2024 / 019644 A1, for example, on page 17, lines 1-24, regarding FIG. 10), can be more easily concealed; see [link to relevant documentation]. Figures 9a-9b However, as Figure 6a As shown, in some embodiments, the recess 4 may be arranged between a pair of cavities 3. This is also shown and discussed with reference to, for example, Figures 4-10 in WO 2024 / 019644 A1, the contents of which are expressly incorporated herein by reference.

[0083] In some embodiments, with the joinery components 1 and 2 in the unlocked state, the angle of the protrusion... It can be smaller than the cavity angle For example, in the unlocked state, the angle of the protrusion. Can be used with cavity angle The difference is 0.5° to 6°, for example, 2° to 4°.

[0084] However, in some embodiments, the protrusion angle Can be used with cavity angle They are essentially the same, for example, differing by less than 0.5°, or by approximately 0°.

[0085] In several preferred embodiments, the insert 6 is formed separately from the second joinery component 2, for example, by injection molding. The insert 6 may comprise a polymer-based material such as a thermoplastic polymer. For example, the polymer-based material may comprise polyoxymethylene (POM) or polypropylene (PP), and optionally also include reinforcing fillers such as glass fiber.

[0086] The protrusion 5 and the insert 6 can be at different angles relative to the second plane M2. and The insert 6 may extend substantially along the normal direction N2 of the second plane M2, preferably such that the insert angle between the principal direction (e.g., axial direction) A of the insert 6 and the direction along the second plane M2 (e.g., along the second direction D2) is... 75°≤ ≤105°, for example, about 90°. However, in some embodiments, the insert angle is... It can deviate from the normal direction N2 by ±15°, for example, 75°≤ ≤105° or 80°≤ ≤100°. The insertion groove 9 may extend in the same direction as the insert 6, thus referring to the above values.

[0087] For example, Figures 4a-4f As shown in 5a-5f, 6d-6f, 7a-7h and 8a-8j, the insert 6 and / or its main body portion 16, such as its envelope, may have a substantially cylindrical shape, although other shapes are equally conceivable.

[0088] Generally, in this document, insert 6 may be displaced and / or compressed along its axial direction A, see [reference needed]. Figure 2a , 2d Arrows C1 and C2 in 3a and 4a respectively indicate inward and outward displacement and / or compression (decompression). For example, the insert can be axially flexible along the axial direction A. The insert 6 can present an extended state S1 and a compressed state S2. For example, in the extended state S1, the insert can be at least partially compressed, e.g., completely uncompressed. The insert 6 can be configured to return towards the extended state S1 when compressed by means of a biasing force, e.g., fully returned. Thus, it can act as a compression spring. The extension lengths F1 and F2 of the insert 6 along the axial direction A can be less in the compressed state S2 than in the extended state S1. The maximum extension length F1 is preferably 30-60 mm, e.g., 45-55 mm. The maximum extension length F2 is preferably 25-55 mm, e.g., 40-50 mm. Alternatively or additionally, the compression amount F1-F2 can generally be 3-8 mm, e.g., 4-6 mm herein.

[0089] The insert may include a spring, such as a static load spring. (As in...) Figures 4a-4c As most clearly seen in 5a, 5d, 6d, 7c, 8a, 8d, 8e, and 8h, the insert 6 may include a flexible, compressible member 6b, preferably in the form of a plurality of interconnected serpentine elements 6c, for example, the serpentine elements 6c may be S-shaped elements. The serpentine elements 6c may be connected to the body portion 16 of the insert 6, preferably integrally (i.e., as a single piece). At least a portion, for example integrally, of the body portion 16 may be configured to be arranged in the insertion groove 9 in a locked state, preferably engaging with the groove walls 9a and / or 9b of the insertion groove 9. Preferably, the serpentine elements 6c are flexible. Furthermore, the insert 6 may be configured to return toward the extended state S1 when compressed by the biasing force through the serpentine elements 6c. The serpentine elements may thus include alternating crests 6d and troughs 6e arranged along the axial direction A.

[0090] At least in the extended state S1, but preferably also in the compressed state S2, adjacent serpentine elements 6c positioned along the same lateral side of the insert 6 can be separated by space 6f along the axial direction A.

[0091] In several preferred embodiments, the width W2 of the recess 4, which is preferably the maximum width, may be greater than the widths W4 and W5 of the insert 6 and / or the insertion groove 9, which are preferably the maximum widths. For example, the width W4 of the insert 6 may be determined at the location of the protrusion 8 (further defined below). The widths W2, W4, and W5 may be determined along the second direction D2. Therefore, in the locked state, the insert 6 and / or the insertion groove 9 may be offset / misaligned relative to the recess 4. For example, the centerline CL1 of the insert 6 and / or the insertion groove 9 may be spaced apart from the centerline CL2 of the recess 4 along the second direction D2, wherein the centerlines CL1 and CL2 extend along the first direction D1.

[0092] The first joinery component 1 and the second joinery component 2 can be locked to each other by relative displacement in a locking direction 17, which extends substantially parallel to the cavity direction P1 and / or the protrusion direction P2, preferably in the final stage of locking. Referring to the first joinery component 1, one component of the locking direction 17 may include a first direction D1, and another component of the locking direction 17 may extend along a first plane M1, for example, along a second direction D2, such as... Figure 2a As shown. Preferably, during the locking process, the third plane M3 is arranged substantially perpendicular to the first plane M1. Locking can be completed without the use of a separate assembly tool.

[0093] During the locking process, the insert 6 can be compressed to a compressed state S2, and subsequently, the insert 6 can at least partially expand towards an expanded state S1 for locking the joinery components 1 and 2. For example, the insert 6 can be fully expanded to the expanded state S1. The insert 6 can be compressed during the locking process by means of the engagement between the insert 6 and the preferred mounting side 1a of the first joinery component 1, see, for example... Figure 2a .

[0094] During the locking process into the insertion groove 7, the insert 6 can be displaced, preferably by being compressed to present a compressed state S2. Subsequently, the insert 6 can be removed from the insertion groove 7, such that it expands at least partially toward the expanded state S1, for example, fully presenting the expanded state S1.

[0095] Each of the protrusions 5 can be received in its respective cavity 3 for locking the joinery parts 1 and 2.

[0096] Generally, in this document, the joinery device 10 can extend along a primary direction X, a secondary direction Y, and a tertiary direction Z that are perpendicular to each other. At least in the locked state, the primary direction X and the tertiary direction Z can extend along a first plane M1 and a second plane M2, and the secondary direction Y can extend along the thickness direction of the first joinery component 1 and along a third plane M3.

[0097] Cavity 3 may be tilted relative to a second direction D2, which may, for example, be parallel to the main direction X. For example, the main direction X and / or the tertiary direction Z may be configured to extend parallel to the subfloor 30, in which the joinery 10 or joinery assembly 20 will be installed. See [reference needed] Figures 9a-9b Although other configurations are equally conceivable.

[0098] In some embodiments, the preferred outer portion of the protrusion 5 may be inclined in a direction away from the insertion groove 9, see, for example... Figures 1a-1c 2a-2c, 3a, and 6c. In some embodiments, the protrusion 5 may be inclined in the direction toward the insertion groove 9, see, for example... Figure 9a . Figures 9a-9b The tilting in the middle can provide improved locking of the joinery by means of an inward force toward the mounting wall 32 generated by the downward gravity on the joinery assembly 20, see the discussion below. In any of these cases, the cavity 3 may tilt corresponding to the tilting of the protrusion 5. In yet another embodiment, some protrusions 5 may tilt in a direction away from the insertion groove 9, and some protrusions 5 may tilt in a direction toward the insertion groove 9, see, for example Figure 6a .

[0099] Generally, in this document, joinery components 1, 2, such as faces 1b, 2b, 1c, 2c and / or side edges 1d, 2d, 1e, 2e and / or sides 1f, 2f, 1g, 2g, can be rectangular or square, although other shapes are equally conceivable. In a non-limiting example, the thicknesses T1, T2 of joinery components 1, 2, such as along the secondary direction Y or the tertiary direction Z, can be 10-32 mm, preferably 12-19 mm. Furthermore, in a non-limiting example, the dimensions of faces 1b, 2b, 1c, 1c, such as along both the primary direction X and the tertiary direction Z, or along both the primary direction X and the secondary direction Z, can range from 300 mm to 1000 mm.

[0100] The insert 6 includes a retaining member 7, which includes at least one protrusion 8, such as two protrusions 8 or even more protrusions 8, such as three to ten protrusions or four to eight protrusions (excluding the end section). The retaining member 7, preferably in the form of an external retaining member 7', is configured to engage with the recess wall 4a in a locked state. At least one protrusion 8, such as at least two protrusions 8, is configured to engage with the recess wall 4a in a locked state (e.g., see...). Figure 3b Therefore, the mating portion of the protrusion 8 can be part of the locking portion 6h, and the locking surface 4c can be part of the mating recess wall 4a.

[0101] In the locked state, the locking portion 6h can mate with the locking surface 4c, and the head surface 8d and the recessed wall 4b of the head portion 6g can be separated by a clearance 15. For example, in the locked state along the second direction D2, the recessed wall 4b can be arranged opposite to the mating recessed wall 4a. The head surface 8d can be arranged in the inner head portion 6j (or the outer head portion 6i). Preferably, the recessed walls 4a and 4b are planar.

[0102] A retaining member 7 may be disposed in an end portion 14 of the insert 6, the end portion 14 being configured to face outward from the insertion groove 9. The retaining member 7 and / or the end portion 14 may extend from the body portion 16, preferably integrally. Along the main direction A, a protrusion 8 may be disposed between a preferably disc-shaped longitudinal end section 6a and the body portion 16. The longitudinal extension of the retaining member 7 may be parallel to the main direction A of the insert 6. In some embodiments, the protrusion 8 may be corrugated on the insert 6.

[0103] Generally, in this document, the protrusion 8 may extend laterally outward from the base surface 7a of the retaining member 7, for example, radially outward. The base surface 7a may include the innermost laterally portion of the retaining member 8. In a non-limiting example, the height Q of the protrusion 8, preferably from the base surface 7a, may be at least 0.3 mm, preferably 0.3-1.0 mm, for example 0.4-0.8 mm. Furthermore, the thickness G of the protrusion 8, preferably the maximum thickness, may be at least 0.1 mm, preferably 0.1-0.8 mm, for example 0.2-0.6 mm. Additionally, the protrusion angle of the top surface 8e of the protrusion 8 relative to the principal axis A... It can be 100°-125°, such as 105°-115°.

[0104] In some embodiments, the height Q along the main direction A of the insert 6 can be constant, see, for example Figures 5a-5f 6d-6f, 7a-7h, and 8h-8j. In some embodiments, the corresponding protrusions in protrusion 8 may extend from the base surface 7a along the main direction A of the insert 6 to different heights Q, see, for example... Figure 3b , 4a -4f, 6d-6f, 7a-7h, and 8a-8c. For example, the height Q gradually increases in the direction towards the topmost portion 6k and gradually decreases in the direction towards the main body portion 16. Generally, here, the height Q can be determined along the transverse (radial) direction TD of the insert 6.

[0105] For example, such as Figures 4a-4f As shown in 5a-5c, 6d-6e, 7a-7h, 8a-8c, and 8h-8j, at least some (e.g., all) of the protrusions 8 may extend around the entire circumference of the retaining member 7, preferably along the circumferential direction C of the insert 6. For example, the protrusions 8 may be annular or disc-shaped. However, in some embodiments, at least one or at least some (e.g., all) of the protrusions 8 may extend around a portion of the circumference of the retaining member 7, see, for example... Figures 5d-5f And 8a-8g. In a non-limiting example, as shown in the figure, the protrusions 8 can be arranged in a raster pattern or a grid pattern.

[0106] The protrusion 8 may be formed of the same material as the insert 6, and preferably is formed integrally with the insert. This material may include a polymer-based material. The protrusion 8 may be rigid, preferably making them substantially non-deformable, especially during the locking process. For example, the material of the protrusion 8 may be more rigid than, for example, the material of the core 18 of the first joinery 1 and / or the second joinery 2, which are wood-based joinery components.

[0107] The protrusions 8 can be separated from each other along the main direction A by spacings U, U1, U2. In some embodiments, and as... Figures 4d-4fAs shown in 5a-5f, 6d-6f, 7a-7h, and 8h-8j, the protrusions 8 can be uniformly spaced such that the spacing U between all adjacent pairs of protrusions 8 can be the same. In some embodiments, the spacings U1 and U2 can vary between different pairs of adjacent protrusions 8. For example, as... Figures 4a-4c As shown in 6d-6f, 7a-7h, and 8a-8c, the spacing U1 between the first pair of adjacent protrusions 8a can be smaller than the spacing U2 between the second pair of adjacent protrusions 8b. The first pair of 8a can be arranged closer to the end segment 6a than the second pair of 8b. It will be apparent to those skilled in the art that there can be more than two pairs, such as multiple pairs, of adjacent protrusions 8, whose spacing U gradually decreases toward the end segment 6a.

[0108] In yet other embodiments, the protrusions 8 may be spaced apart from each other by a distance V along the circumferential direction C of the insert 6, see, for example Figures 5d-5f Figures 8d-8f illustrate the spacing V together with the spacing U. The circumferential direction C may be perpendicular to the principal direction A.

[0109] In a non-limiting example, the spacing U, U1, U2 and / or V can be 0.3-1.5 mm, for example 0.4-1.0 mm.

[0110] The lateral extension length / lateral extension range E of the protrusion 8 can generally vary along the main direction A, for example, decreasing towards the end segment 6a. Preferably, the member 7 is generally tapered in the direction towards the end segment 6a. The end portion 14 may have a frustoconical shape. For example, the envelope 7b of the lateral extension range E (which is a virtual surface) can be arranged along a straight line, for example, such that the total envelope rotating about the main direction A is arranged along the frustoconical surface, see [reference needed]. Figure 4b In some embodiments, such as Figure 4d As shown, the envelope 7b of the lateral extension range E can be arranged along a concave curve, for example, such that the entire envelope is arranged along a curved truncated conical surface.

[0111] For example, such as Figures 4a-4c As shown in 5a-5f, for example, the lateral extension range E of the topmost protrusion 8c arranged in the end section 6a may be smaller than the lateral extension range E of the protrusion 8 arranged longitudinally inside the topmost protrusion 8c along the main direction A. However, in some embodiments, such as Figures 4d-4f As shown, the topmost protrusion 8c may have a larger lateral extension range E than the protrusion 8 arranged longitudinally inside the topmost protrusion 8c along the main direction A.

[0112] Furthermore, the recess wall 4a preferably tapers in the depth direction 12 of the recess 4. The depth direction 12 may extend perpendicular to the first plane M1. For example, the recess wall 4a may have a truncated conical shape.

[0113] In some embodiments, at least some (e.g., all) of the protrusions 8 may extend from the base surface 7a of the retaining member 7 to a virtual truncated conical surface, which forms a non-zero angle with respect to the base surface 7a. .

[0114] In a non-limiting example, the angle of inclination between the generally tapered retaining member 7 (e.g., the envelope 7b of the lateral extension E of the protrusion 8) and the principal direction A. It can be 5°≤ ≤20°, for example, about 10°. Alternatively or additionally, in a non-limiting example, the wall angle between the recess wall 4a and the normal direction N1 of the first plane M1. It can be 5°≤ ≤20°, for example, about 10°. Furthermore, the base surface 7a may be at an angle of, for example, 5°-20° relative to the principal direction A. Extended. Therefore, the angle relative to the base surface 7a It can correspond to the difference. .

[0115] However, in some embodiments, the recessed wall 4a may extend along the first direction D1, preferably this is achieved by having parallel recessed walls 4a, 4b, see [reference needed]. Figure 6b For example, the recess 4 may be formed as a cylinder and / or the insert 6 may be substantially cylindrical. In any embodiment herein, for example in Figures 1a-1c Such a configuration is conceivable in any of the following: 2a-2d, 3a-3b, 4a-4f, 5a-5f, 6a-6f, 7a-7h, 8a-8g, and 9a-9b.

[0116] According to some embodiments, and for example as Figure 6c-6f As shown in 7a-7h and 8a-8g, at least one protrusion 8, such as multiple protrusions 8, of the retaining member 7 preferably in the form of an internal retaining member 7” may be arranged in the body portion 16. In particular, the protrusion 8 may be arranged in an axially outer segment 16a of the body portion 16, which is configured to face and / or engage with the groove walls 9a, 9b of the insertion groove 9 in the locked state. For example, the axially outer segment 16a may be configured to be located near the entrance of the insertion groove 9 into the mounting area 2a. The body portion 16 may mate with, for example, each of the first groove wall 9a and the oppositely arranged second groove wall 9b.

[0117] It needs to be emphasized that, Figures 7a-7b 7c-7e, 7f-7h or 8a-8c Figure 8d as well as Figure 8e-8f or Figure 8g or Figure 8h-8g Any of the embodiments can be used in, for example Figures 1a-1c In the joinery parts 1 and 2 shown in 2a-2c, 3a-3b and 6c.

[0118] The protrusion 8 can be configured to mate with at least one of the groove walls 9a, 9b, for example, each of the oppositely arranged groove walls 9a, 9b, and optionally configured to mate with a locking surface 4c, which is preferably arranged in the recessed wall 4a. In the first example, as Figure 8g-8j As shown, the at least one protrusion 8 may be arranged only in the body portion 16. Here, the head surface 8d of the preferably generally tapered head portion 6g may be, for example, substantially flat and / or smooth. This insert 6 provides smoother, more gentle unlocking of the joinery parts 1, 2, while providing a more secure arrangement of the insert 6 in the insertion groove 9. Note that Figure 8d Insert 6 in the middle can represent Figure 8g The front perspective view of insert 6 in the middle, where the corresponding one is similar to Figure 8e The rear perspective view does not include the protrusion 8 in the end portion 14. In the second example, as... Figure 6c-6f As shown in 7a-7h and 8a-8f, at least two, for example, multiple protrusions 8 may be arranged in the main body portion 16 and the end portion 14, which is configured to mate with the recess 4. As described elsewhere herein, the end portion 14 may generally be tapered, and a portion of the retaining member 7 of the protrusions 8 is arranged in the end portion 14.

[0119] The outer retaining member 7' and / or the inner retaining member 7" may extend only around a portion of the circumference of the retaining member 7, for example, extending along the circumferential direction C, see example Figure 6d , 8a And 8d-8e. Alternatively, the outer retaining member 7' and / or the inner retaining member 7" may extend around the entire circumference of the retaining member 7, see, for example Figure 6d , 7c 7f, 8a and 8h.

[0120] The protrusion 8 arranged in the axially outer segment 16a can extend laterally to the outside of the axially inner segment 16b of the main body 16, see, for example Figure 6c-6f 7a-7b, 7f-7h, and 8a-8g. Alternatively, the protrusion 8 arranged in the axially outer segment 16a may extend into the axially inner segment 16b, or laterally extend into the inner side of the axially inner segment 16b, see, for example... Figures 7c-7eAnd 8h-8j. The lateral extension range may extend along the lateral direction TD of the insert 6. For example, any of the above relationships may be specified in the front view and / or side view of the insert 6. In any of these embodiments, the axial outer segment 16 and the axial inner segment 16b may be located on the same lateral side of the insert 6.

[0121] Generally, in this paper, the effect of retaining member 7 can increase as the load increases. For example... Figure 6c As shown, when the first joinery component 1 (e.g., the first surface 1b) is loaded, a force F pointing along the first direction D1 is generated, causing the first joinery component 1 to shift relative to the second joinery component 2 in a direction opposite to the first direction D1 and along the second direction D2 due to the inclined protrusion 5 arranged in the inclined cavity 3. The outer retaining member 7' can be activated by increasing the engagement strength with the recess wall 4a due to the resultant force RF acting on the insert 6 along the second direction D2 from the recess 4. The force RF also presses the insert 6 against the insertion groove 9, thereby activating the inner retaining member 7' by increasing the engagement strength with the second groove wall 9b through the opposite force RF' in the insertion groove 9. Activating the outer retaining member 7' and the inner retaining member 7' by load can counteract the unlocking of the joinery components 1 and 2.

[0122] The quantities specified here, especially the angles The extension amount / extension range / extension length E, F1, F2, G, HL, K, L, Q, T1, T2, U, U1, U2, V, W1-W5 can be determined by, for example, a profile projector from Mitutoyo or Dravitec AB. The joint gap J can be measured with a digital dial indicator.

[0123] Figures 9a-9b An embodiment of the joinery component 20 is shown, which includes, for example, according to Figures 1a-1c The joinery 10 and / or insert 6 of any embodiment shown in 2a-2d, 3a-3b, 4a-4f, 5a-5f, 6a-6f, 7a-7h, and 8a-8j, and further include at least one additional joinery component 1', 2, 2', such as multiple additional joinery components. In fact, this particular embodiment includes two joinery components 10, wherein two second joinery components 2 are locked to the same first joinery component 1. The mounting side 1a may be the inner first surface 1b of the joinery assembly 20. The joinery assembly 20 may be a furniture assembly. For example, the furniture assembly may be a cabinet assembly or a shelf assembly. Figure 9bA wall-mounted cabinet assembly is shown, comprising a first joinery component 1 that forms the bottom joinery component of the wall-mounted cabinet assembly, for example, a bottom joinery component located at the bottom along the secondary direction Y. The wall-mounted cabinet assembly is arranged at a vertical distance 31 from the underlying floor 30 and is secured to the mounting wall 32 by any means known to those skilled in the art, such as by screws and / or brackets.

[0124] For example, the additional joinery components 1', 2, 2' may be selected from the group consisting of the side joinery component 2, the top joinery component 1', and the rear joinery component 2'. The additional joinery components 1', 2, 2' may be selected from any of the embodiments described herein, such as... Figures 1a-1c 1, 2a-2b, and 3a-3b, or by any means known in the art, such as by screws or by inclined rod-like elements and insert recesses and compressible locking elements and recesses (e.g., disclosed in WO2023 / 143756 A1), are connected to each other and / or connected to the joinery device 10. Optionally, one or more joinery components 1, 1', 2 may include a connecting channel 21 for connecting the rear joinery component 2'.

[0125] In any embodiment herein, the end portion 14 may include an indicator 14a, such as a notch, for indicating the rotational position of the insert 6 about the main axis A, see [reference]. Figure 8h-8i .

[0126] Example

[0127] The reference group R0, which includes reference samples tested according to the peak load test method and the impact load test method, and three groups R1, R2, and R3, which include samples comprising joinery devices or joinery components. Each sample in each group R0, R1, R2, and R3 includes first and second joinery components in the form of panels, with dimensions of 130 mm × 16 mm × 60 mm and 180 mm × 300 mm × 16 mm in the X, Y, and Z directions, respectively, and has a core in the form of particleboard and a decorative layer comprising melamine-formaldehyde resin. The first joinery component includes a recess with a wall angle. The conical recess wall has a 10° truncated cone shape. The maximum width W2 corresponding to the diameter of the recess is 11.2 mm. Groups R0, R1-R3 also include inserts made of pure POM without any filler, and are identical in design except for the head portion. The inserts have truncated conical end portions and a maximum extension length F1 of approximately 51 mm, and each head portion has a minimum lateral extension length / lateral extension range E of 4 mm, a head length HL of 5.3 mm, and a 10° tilt angle. Reference group R0 includes an insert without any protrusions, having the features specified in WO 2023 / 191694 A1. Figures 1a-1c The embodiment in the text has a generally smooth head portion and a surface roughness of 27 according to standard VDI (Verein Deutscher Ingenieure). All projections of R1-R3 are perpendicular to the base plane with G=0.3 mm. The first group R1 comprises six evenly spaced protrusions (see...). Figures 5a-5c ), where U = 0.8 mm, Q = 0.7 mm. The second group R2 includes five along concave curves (see...). Figures 4d-4f The third group R3 consists of four protrusions whose spacing gradually decreases towards the end section (see [reference]). Figures 4a-4c ), where 0.9 mm ≤ U ≤ 1.3 mm, 0.5 mm ≤ Q ≤ 1.0 mm, and the base surface at an angle =16° extension.

[0128] The strength of the locking device was estimated based on the peak load test method when an excessive load was applied to a sample of the bottom panel of a joinery assembly, for example, when configured for wall mounting. Samples in groups R0, R1-R3 were treated for at least 24 hours at a temperature of 23±2°C and a relative humidity of 50±5% RH. Similar to... Figures 9a-9b The joinery components 1 and 2 in the sample assemble the two side panels onto the bottom panel, similar to... Figure 9b The top joinery component 1' assembles a sample of a top panel onto the side panels (without using a back panel). A hole is drilled at the geometric center of the top panel so that the pressure bar can pass freely through it. A hole is drilled at 100% depth and 75% width (centered) of the bottom panel (corresponding to, for example...). Figures 9a-9b Loads were applied along the principal direction X and the tertiary direction Z. Then, in each of groups R0, R2, and R3, the arithmetic mean static load in the form of the peak fracture load of three samples of the joinery assembly was measured, and the results are shown in... Figure 11a (See shaded bar). From Figure 11a It is clear that the samples in the second group R2 and the third group R3 resisted higher loads compared to the samples in the reference group R0.

[0129] The other samples in groups R0', R1', R2', and R3' were also tested according to the peak load test method and the impact load test method. The samples in groups R0', R1', R2', and R3' are identical to those in groups R0, R1, R2, and R3, respectively, except that the concave portion is cylindrical, thus possessing a wall angle. The concave wall is approximately 0°. The maximum width W2 corresponding to the diameter of the concave portion is 11 mm. Therefore, this cylindrical concave portion has a smaller contact area than a conical concave portion.

[0130] Then, for three joinery component samples in each group R0', R2', and R3', the arithmetic mean static load in the form of the peak load at fracture was measured, and the results are shown in... Figure 11a (See solid line in the middle). From Figure 11a It can be inferred that the samples in the second group R2' (or the third group R3') resist higher (or lower) loads than the samples in the reference group R0'. It can also be inferred that while the samples in the second group R2 and R2' can withstand approximately the same load, the samples in the third group R3 can withstand a higher load than the samples in the third group R3'. In other words, the conical recess performs better than the cylindrical recess.

[0131] According to the impact load test method, and referring to Figures 10a-10c The accompanying diagram shows in detail the relevant test equipment, in which the effects of drop weight on the five assembled samples of each of groups R0, R1-R3 arranged in the equipment along the first direction D1 are measured using a digital dial indicator. Figure 2a The engagement gap J is determined by the test method. The results show the mechanical durability of the locking device under impact load.

[0132] After adjustments as described above, the method includes the following steps for each assembled sample in groups R0, R1-R3: The sample is placed on the equipment, and the joint gap J is measured. (Example...) Figures 10a-10c As shown, a uniform counterweight element 40, in the form of a vertically aligned disc with a mass of 0.740 kg, having a diameter of 80 mm and a width of 9.3 mm, was repeatedly dropped and impacted the first surface of the side panel at a vertical distance of 100 mm from the bottom panel sample. The joint gap J generated in the joint was measured after each impact, and the arithmetic mean was summarized in... Figure 11b In the middle. When the topmost part of the insert is located at or above the first surface extending along the mounting side of the bottom panel, for example when the bottom panel breaks and / or when the insert is completely dislodged from the recess, the counterweight is dropped repeatedly until the release state is achieved. Figure 11c The arithmetic mean of the impacts that reach the release state is summarized.

[0133] Based on the above, it can be deduced that for any given number of impacts, the arithmetic mean joint gap J of the samples in the second group R2 (or each of the first group R1 and the third group R3) is less than (or greater than) the arithmetic mean joint gap in the reference group R0. Therefore, the samples in the second group R2 (or the first group R1 and the third group R3) generate the highest (or lowest) average friction between the insert and the recess. Furthermore, while the samples in the second group R2 and the third group R3 experience an average of more impacts than the samples in the reference group R0, the samples in the first group R1 experience fewer impacts.

[0134] In fact, it was found that the friction of the second set of R2 samples was too high for some applications involving particleboard as the core, as unlocking some of these samples resulted in their breakage, such as fragmentation. As mentioned above, the samples are unlocked through unlocking hole 22. On the other hand, it was found that unlocking the third set of R3 samples was less destructive and generally did not cause any damage to the samples. Therefore, the inventors were surprised to find that, at least for some applications, such as those involving particleboard as the core, the third set of R3 samples could constitute a balanced compromise for providing sufficiently high locking strength while maintaining the possibility of disassembling the joinery components with little or no damage.

[0135] Several different aspects of this disclosure have been described above with reference to several embodiments. However, as will be readily understood by those skilled in the art, other embodiments besides those disclosed above are also possible within the scope of this disclosure. For example, it is clear that in some embodiments, the outer head portion 6i and / or the inner head portion 6j may mate with the recess wall 4b such that there is no clearance 15.
